[0002] Lathe fixtures are devices used to clamp workpieces for processing on lathes. When processing on lathes, workpieces usually need to be clamped in a fixed position to ensure processing accuracy and safety. The design and selection of fixtures are crucial to processing quality and efficiency.
[0003] The design and selection of lathe fixtures have an important impact on processing quality and efficiency. Appropriate fixtures can improve processing accuracy, reduce processing time and cost, and ensure processing safety. Therefore, when selecting lathe fixtures, it is necessary to consider the characteristics of the workpiece, processing requirements, and the specifications and performance of the lathe to ensure that the appropriate fixture is selected to meet the processing needs.
[0004] At present, the clamps for lathes are usually composed of the clamp body, clamp seat, clamp base, clamp clamping device, etc. The design of the clamp needs to take into account the shape, size and processing requirements of the workpiece to ensure that the workpiece can be firmly clamped in the correct position. However, the clamping device needs to rotate the threaded rod when adjusting. However, when the adjustment range is large, the adjustment is very time-consuming and inefficient. Secondly, it cannot be disassembled, and damage to a single component may require the replacement of the entire device. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Reference Figure 1-Figure 3 The utility model provides an embodiment: it includes a workbench 1, a cylindrical block 2 is fixedly connected to the bottom end of the workbench 1, a disc 8 is rotatably connected to the outer wall of the cylindrical block 2, a handle 10 is fixedly connected to the side wall of the disc 8, and the handle 10 can be dragged to drive the disc 8 to rotate with the cylindrical block 2 as the center of the circle, a slider a5 is slidably connected to the inner wall of the workbench 1, a clamping block 6 is fixedly connected to the top of the slider a5, the slider a5 slides along the inner wall of the workbench 1 to drive the clamping blocks 6 to move closer or separate from each other to clamp the workpiece, a slider b7 is arranged in the central area of the slider a5, a slide groove 9 is provided on the inner wall of the disc 8, the outer wall of the slider b7 is slidably connected to the inner wall of the slide groove 9, when the disc 8 rotates, the slider b7 is driven to slide along the inner wall of the slide groove 9, and at the same time, the slider a5 slides along the inner wall of the workbench 1, driving the four groups of clamping blocks 6 to move closer or separate from each other to clamp the workpiece, and the outer wall of the cylindrical block 2 is slidably connected to the bottom plate 14 The inner wall of the handle 10 is slidably connected with a buckle assembly, which includes two groups of blocks a12. The interval between the two groups of blocks a12 is elastically connected by a reset spring a11. The two ends of the reset spring a11 are respectively fixedly connected to the inner ends of the two groups of blocks a12. Pressing the block a12 inward can squeeze the reset spring a11 into the groove of the handle 10. At the same time, the elastic force generated by the deformation of the reset spring a11 gives the block a12 an outward thrust. The side walls of the workbench 1 and the bottom plate 14 are both provided with a slot 13. The outer wall of the block a12 is engaged with the inner wall of the slot 13. After the block a12 is completely pressed into the groove of the handle 10, the engagement with the slot 13 is released. At this time, the handle 10 can be turned to rotate the disc 8, and the clamping block 6 is controlled to clamp. The outer wall of the slider a5 is slidably connected to the inner wall of the bottom plate 14, and the slider b7 is relatively thick and clamped between the workbench 1 and the bottom plate 14.
[0027] Reference Figure 2 and Figure 3The inner wall of the cylindrical block 2 is slidably connected with a card block b4, and the interval between the two groups of card blocks b4 is elastically connected by a reset spring b3. The two ends of the reset spring b3 are respectively fixedly connected to the inner ends of the two groups of card blocks b4. The bottom of the card block b4 is set as an inclined surface, which is squeezed by the inner wall of the central circular groove of the disc 8 or the bottom plate 14, which will squeeze the reset spring b3 inward to retract. After the bottom plate 14 is installed, the reset spring b3 will push out the two groups of card blocks b4, and the top of the card block b4 will be clamped with the outer wall of the bottom of the bottom plate 14, thereby fixing the clamp components such as the disc 8 and the bottom plate 14 together. When they need to be removed, they can be removed one by one by manually pressing the card block b4. If any parts are damaged or severely worn, only the parts can be replaced, saving costs.
[0028] Working principle: When it is necessary to clamp the workpiece, press the block a12 inward until it is disengaged from the upper and lower groups of slots 13, then turn the handle 10 to drive the disc 8 to rotate with the cylindrical block 2 as the center, so that the slider b7 slides along the inner wall of the slot 9, and the slider a5 slides along the inner wall of the workbench 1 and the bottom plate 14, so that the four groups of clamping blocks 6 are close to each other to clamp the target workpiece. After the adjustment is completed, release the block a12, and the reset spring a11 will push the two groups of blocks a12 into the slot 13 to fix the device. When a part of the device is damaged and needs to be replaced, press the block b4 inward until it is completely received in the slot of the cylindrical block 2. At this time, the bottom plate 14 and the disc 8 can be removed one by one, and the clamping block 6 can be slid out from the edge of the workbench 1. The slider b7 is thick and cannot be pulled out from the slots of the workbench 1 and the bottom plate 14. In this way, only some parts can be replaced according to the damage, saving costs.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
