Description

Technical Field

[0001] This utility model relates to the field of machining irregularly shaped copper cutting blocks, and in particular to an adaptive guiding and positioning structure for curved surfaces of irregularly shaped copper cutting blocks. Background Technology

[0002] Irregularly shaped copper cutting blocks are copper cutting tool components with special shapes. Copper itself has excellent electrical and thermal conductivity. The former gives it an advantage in applications involving current conduction, while the latter helps dissipate heat during machining, reducing problems such as tool deformation due to overheating. Its "irregular" characteristic lies in its shape, which is not a conventional geometric shape but a complex shape customized to specific machining needs. This allows it to better conform to the machined surface, enabling precise cutting, engraving, and other operations.

[0003] Because irregularly shaped copper cutting blocks have curved surfaces, it is difficult for workers to accurately process the same curved surface of the raw material based on the existing curved surface of the irregularly shaped copper cutting blocks. The existing processing method usually involves workers placing the irregularly shaped copper cutting block on the surface of the raw material and then drawing the curved surface outline of the irregularly shaped copper cutting block on the raw material with a scribing pen. This scribing method relies on manual operation, which is not only inefficient, but also makes it difficult to guarantee the accuracy and consistency of the scribing curve. In order to address this technical problem, this application proposes an adaptive guiding and positioning structure for the curved surface of irregularly shaped copper cutting blocks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a curved surface adaptive guiding and positioning structure for irregularly shaped copper cutting blocks. This structure involves bringing the ball bearing at the rear end of a reference rod into contact with the curved surface of the irregularly shaped copper cutting block, and moving the reference rod via a sliding block. A movable telescopic rod then moves the fixed rod, achieving synchronous movement between the reference rod and the fixed rod. A scribing pen marks the movement trajectory onto the raw material, ensuring the accuracy of the scribing lines and facilitating processing, thus significantly improving processing efficiency. Furthermore, by using clamping plates and adjusting the clamping force with bolts and nuts, the height of the scribing pen can be easily adjusted to accommodate raw materials of varying heights. This ensures that the bottom of the scribing pen contacts the top of the raw material, guaranteeing a clear curve at the marked area.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adaptive guiding and positioning structure for a non-circular copper knife block includes a base plate. A slide rail is fixedly connected to the top of the base plate. Two sliders are slidably connected to the top of the slide rail. Mounting blocks are bolted to the top of the sliders. The top midpoints of the two mounting blocks are connected by a telescopic assembly. A fixed telescopic rod is fixedly connected to the rear end of the top of the mounting block. A reference rod is slidably connected to the right end of the fixed telescopic rod. A movable rod is slidably connected to the left end of the fixed telescopic rod. A clamping assembly is provided at the rear end of the movable rod. A bidirectional lead screw is threadedly connected to the middle of the mounting block. A rotating sleeve is fixedly connected to the middle of the bidirectional lead screw. Limit blocks are provided at both ends of the rotating sleeve. The limit blocks are rotatably connected to the bidirectional lead screw. The bottom of the limit blocks is fixedly connected to the slide rail.

[0007] Furthermore, the telescopic assembly includes a groove located at the middle of the top of the two mounting blocks, a movable block is slidably connected in the groove, and a movable telescopic rod is fixedly connected to the top of the movable block.

[0008] Furthermore, springs are provided at the rear of both ends of the movable telescopic rod, with one end of the spring connected to the movable telescopic rod and the other end of the spring connected to the fixed telescopic rod.

[0009] Furthermore, the clamping assembly includes a clamping piece located at the rear end of the movable rod, a fixing strip is fixedly connected to the outer wall of the clamping piece, the front end of the clamping piece is connected to the movable rod by bolts and nuts, and a scribing pen is provided at the rear end of the movable rod.

[0010] Furthermore, the front end of the movable rod is fixedly connected to the left end of the movable telescopic rod, and a fixing strip is fixedly connected to the inner wall of the rear end of the movable rod.

[0011] Furthermore, a placement platform is fixedly connected to the top rear end of the base plate.

[0012] Furthermore, the front end of the reference rod is fixedly connected to the right end of the movable telescopic rod, and a ball bearing is provided at the rear end of the reference rod.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the ball bearing at the rear end of the reference rod contacts the curved surface of the irregular copper blade block, and the reference rod is moved by moving the slider. Then, the fixed rod is moved by the movable telescopic rod, thereby realizing the synchronous movement of the reference rod and the fixed rod. The motion trajectory is engraved on the raw material by the engraving pen, ensuring the accuracy of the engraving pen, thus facilitating the processing of the raw material by the staff and greatly improving the processing efficiency of the raw material.

[0015] 2. In this utility model, by setting a clamping piece and adjusting its clamping force with bolts and nuts, the height of the scribing pen can be easily adjusted by the staff to adapt to raw materials of different heights, so that the bottom of the scribing pen can contact the top of the raw material, thereby ensuring that the curve at the scribing point is clear.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figs. 1-3This utility model provides an embodiment of an adaptive guiding and positioning structure for a shaped copper knife block, comprising a base plate 1, a slide rail 2 fixedly connected to the top of the base plate 1, two sliders 3 slidably connected to the top of the slide rail 2, the sliders 3 being able to slide on the top of the slide rail 2, mounting blocks 4 being bolted to the top of the sliders 3, a groove being formed at the middle of the top of the two mounting blocks 4, a moving block 14 being slidably connected in the groove, a movable telescopic rod 7 being fixedly connected to the top of the moving block 14, the movable telescopic rod 7 being able to move on the top of the mounting block 4 by setting the moving block 14, a fixed telescopic rod 6 being fixedly connected to the rear end of the top of the mounting block 4, a reference rod 9 being slidably connected to the right end of the fixed telescopic rod 6, by contacting the ball bearing at the rear end of the reference rod 9 with the curved surface of the shaped copper knife block, when the reference rod 9 moves along the curved surface of the shaped copper knife block, the reference rod 9 can be pushed forward, and the movable rod 10 can be moved by the movable telescopic rod 6, thereby realizing the synchronous movement of the reference rod 9 and the movable rod 10, and thus positioning the shaped copper knife block... The curved shape is drawn on the raw material using a scribing pen 13. A movable rod 10 is slidably connected to the left end of the fixed telescopic rod 6. A clamping piece 15 is provided at the rear end of the movable rod 10. The clamping piece 15 has a certain elasticity, and a fixing strip 17 is fixedly connected to the outer wall of the clamping piece 15. The front end of the clamping piece 15 is connected to the movable rod 10 via bolts and nuts. A scribing pen 13 is provided at the rear end of the movable rod 10. When installing the clamping piece 15, it is inserted into the rear end of the movable rod 10, and then the movable rod is secured using bolts and nuts. The rear end of 10 clamps the clamping plate 15, and then the scribing pen 13 is installed on the rear of the clamping plate 15. After that, the bolt and nut are tightened, so that the scribing pen 13 is clamped by the clamping plate 15. The middle of the mounting block 4 is threaded with a double screw 5, and the middle of the double screw 5 is fixedly connected with a rotating sleeve 8. By rotating the rotating sleeve 8, the double screw 5 can be rotated. Limit blocks are provided at both ends of the rotating sleeve 8. The limit blocks are rotatably connected to the double screw 5, and the bottom of the limit blocks is fixedly connected to the slide rail 2.

[0025] Springs 11 are installed at the rear of both ends of the movable telescopic rod 7. One end of the spring 11 is connected to the movable telescopic rod 7, and the other end is connected to the fixed telescopic rod 6. The springs 11 ensure that the ball bearing at the rear end of the reference rod 9 is always in contact with the curved surface of the irregularly shaped copper blade block. The front end of the movable rod 10 is fixedly connected to the left end of the movable telescopic rod 7. A fixing strip 16 is fixedly connected to the inner wall of the rear end of the movable rod 10. When the clamping piece 15 is inserted into the rear end of the movable rod 10, the fixing strip 16 and fixing strip 17 limit the clamping piece 15 to prevent it from being inserted too deeply. A placement platform 12 is fixedly connected to the top rear end of the base plate 1. Universal clamps are installed on the left and right sides of the top of the placement platform 12. The universal clamps are usually composed of a base, positioning elements, clamping elements, and other basic parts. The base provides stable support for the entire clamp and generally has good rigidity. Positioning elements, such as positioning pins and positioning blocks, can be combined and adjusted according to the shape and processing requirements of different workpieces to achieve workpiece positioning. Clamping elements such as bolts and pressure plates can firmly clamp the workpiece onto the fixture. The universal fixture on the left is used to hold the raw material to be processed, and the universal fixture on the right is used to hold the existing irregularly shaped copper cutting blocks. The front end of the reference rod 9 is fixedly connected to the right end of the movable telescopic rod 7. The rear end of the reference rod 9 is equipped with ball bearings, which contact the curved surface of the irregularly shaped copper cutting block and can roll on its surface.

[0026] Working principle: First, the irregular copper knife block and the raw material are clamped by the clamps at the top left and right ends of the placement table 12. The irregular copper knife block is located at the right end of the placement table 12, and the outer wall of the irregular copper knife block is in contact with the ball at the rear end of the reference rod 9. The raw material is located at the left end of the placement table 12 and at the bottom of the scribing pen 13. Then, by moving the mounting block 4, the ball can roll on the curved surface of the irregular copper knife block. The irregular copper knife block applies a forward pushing force to the reference rod 9 through the ball and stretches the spring 11. By setting the spring 11, the ball can always be in contact with the curved surface of the irregular copper knife block. When the reference rod 9 moves forward, the movable telescopic rod 7 can move the movable rod 10 forward to achieve synchronous movement of the reference rod 9 and the movable rod 10. Then, the movable rod 10 moves the scribing pen 13. The scribing pen 13 draws the movement trajectory of the ball, that is, the curved shape of the irregular copper knife block, on the top of the raw material, so as to facilitate the workers to process the raw material into irregular copper knife blocks.

[0027] When the distance between the two mounting blocks 4 needs to be adjusted, rotating the rotating sleeve 8 can rotate the bidirectional lead screw 5, which in turn moves the two mounting blocks 4, thereby adjusting the distance between them. By setting the fixed telescopic rod 6 and the movable telescopic rod 7, the distance between the two mounting blocks 4 can be adjusted without interfering with the synchronous movement of the movable rod 10 and the reference rod 9. When the height of the scribing pen 13 needs to be adjusted, the clamping force of the clamping piece 15 on the scribing pen 13 is reduced by loosening the nut, thereby adjusting the height of the scribing pen 13 to accommodate raw materials of different heights.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
