kale fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include compact structure, rapid, convenient, and labor-saving operation, ensuring high machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes obsolete and is scrapped due to inability to reuse. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning datum of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the correct relative position of the workpiece with respect to the cutting tool and the machining motion of the machine tool. It usually consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

kale fixture types

1) Standard rectangular electromagnetic chuck Application: Rectangular table surface grinders. 2) High-power electromagnetic chuck Application: Milling machines, planers, machining centers. 3) Fine-pole electromagnetic chuck Application: Rectangular table surface grinders, milling machines. 4) Multi-functional high-power electromagnetic chuck Application: Rectangular table surface grinders. 5) Rotary electromagnetic chuck Application: Various surface grinders. 6) Electromagnetic chuck for cutter grinding Application: Cutter grinders. 7) Circular electromagnetic chuck (concentric type) Application: Circular table surface grinders. 8) Circular electromagnetic chuck (radial pole type) Application: Circular table surface grinders. 9) Circular electromagnetic chuck (plum blossom pole type) Application: Circular table surface grinders. An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being machined by the suction force generated by the chuck body after the electromagnetic coil is energized. The electromagnetic chuck consists of several parts including an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

kale fixture features

Mechanical grippers commonly use compressed air as the power source, achieving finger movement through a transmission mechanism. Based on the different motion trajectories of the fingers when clamping the workpiece, mechanical grippers are divided into: 1) Arc opening/closing type: Driven by the transmission mechanism, the motion trajectory of the finger tips is an arc. This type of gripper has strict requirements on the dimensions of the clamped part of the workpiece; otherwise, it may cause abnormal workpiece status. 2) Arc parallel opening/closing type: In this type of gripper, the two fingers perform parallel opening and closing movements during operation, while the motion trajectory of the finger tips is an arc. The illustrated gripper shows two cases where a parallelogram transmission mechanism drives the parallel opening and closing of the fingers. 3) Linear parallel opening/closing type: The motion trajectory of the two fingers of this type of gripper is linear, and the clamping surfaces of the two fingers remain parallel at all times. A cam mechanism is used to achieve parallel opening and closing of the two fingers. Inclined cam slots are machined on the sliding blocks of each finger. When the piston rod moves up and down, rollers mounted on its end move within the cam slots, achieving parallel clamping motion of the fingers. Alternatively, a rack-and-pinion mechanism is used; when the rack at the end of the piston rod drives the gear to rotate, the racks on the fingers move linearly, causing the two fingers to open and close in parallel to clamp the workpiece.

kale fixture applications

1) Can stably ensure the machining accuracy of the workpiece: When clamping a workpiece with a fixture, the positional accuracy of the workpiece relative to the cutting tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, making the machining accuracy of a batch of workpieces consistent. 2) Can reduce auxiliary time and improve labor productivity: Using fixtures to clamp workpieces is convenient and fast; workpieces do not require scribing and alignment, significantly reducing auxiliary time; clamping workpieces in fixtures increases their rigidity, allowing for increased cutting parameters; fixtures capable of clamping multiple workpieces or at multiple stations can be used, and high-efficiency clamping mechanisms can be adopted to further improve labor productivity. 3) Can expand the usage range of machine tools and achieve multi-functionality: According to the forming motion of the machining machine tool, attaching different types of fixtures can expand the original process range of the machine tool. For example, installing a boring template on the carriage of a lathe or on the worktable of a radial drilling machine allows for boring processing of box-type parts. 4) Ensure machining accuracy: Using fixture installation can accurately determine the mutual position between the workpiece, machine tool, and cutting tool. The positional accuracy of the workpiece is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Improve productivity and reduce costs: Clamping workpieces with fixtures allows for rapid positioning and clamping without alignment, significantly reducing auxiliary time; clamping workpieces with fixtures increases workpiece rigidity, allowing for increased cutting parameters; fixtures can clamp multiple workpieces or at multiple stations, and high-efficiency clamping mechanisms can be adopted. These factors are all beneficial for improving labor productivity. Additionally, using fixtures stabilizes product quality, reduces scrap rates, allows for the assignment of workers with lower technical grades, and significantly reduces production costs. 6) Expand the process range of machine tools: Using special fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality. For example, after installing boring template fixtures on lathes or radial drilling machines, boring processing can be performed on hole systems of box-type parts; through special fixtures, lathes can also be converted for use as broaching machines, fully leveraging the role of general-purpose machine tools. 7) Reduce workers' labor intensity: Clamping workpieces with fixtures is convenient and fast. When using pneumatic, hydraulic, or other clamping devices, workers' labor intensity can be reduced.
