[0011] The effect achieved by the above components is that the directional bolts can prevent the relative rotation of the copper rod and ensure stable contact with the workpiece.
[0012] This utility model provides an improved conductive device for a planar electrolytic grinding fixture, which has the following improvements and advantages compared with the prior art:
[0013] Firstly, this utility model uses a pusher to drive a clamping component to move towards the clamping component on the clamping seat, thereby achieving the purpose of clamping and positioning the workpiece. During the clamping process, the workpiece pushes the telescopic conductive component and causes it to be compressed and retracted into the clamping component. When the workpiece is clamped or released, the telescopic conductive component is always in close contact with the workpiece to conduct electricity, which replaces the power supply method of the traditional brush, ensures the stability of the conductivity, and improves the problem of the potential risks of the traditional brush being exposed.
[0014] Secondly, this utility model enables the sliding installation of copper rods through stepped holes. Springs and spring seats can be sleeved on the terminals of copper rods. Copper rods, in conjunction with convex rings, are pre-tightened by the springs, ensuring that the end of the copper rod in contact with the workpiece protrudes from the outer wall of the clamping block. The spring seats are fixed to the stepped holes via threaded connections. When the workpiece is clamped, the copper rod is subjected to pressure and retracts into the stepped holes, compressing the springs and ensuring close contact between the copper rod and the workpiece, thus achieving electrical conductivity.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0021] This utility model provides an improved conductive device for a planar electrolytic grinding fixture. The technical solution of this utility model is as follows:
[0022] In embodiments of this utility model, such as Figures 1-2 As shown, a conductive device for a planar electrolytic grinding fixture includes a clamp 1 made of nylon, which insulates the workpiece from the machine tool while clamping it. The clamp 1 is fixed to the fixture base by bolts. A pusher 2 is fixed to one end of the clamp 1. The pusher 2 includes a screw 21 threaded into the end of the clamp 1. A handle 22 is fixed to one end of the screw 21. The end of the screw 21 away from the handle 22 is rotatably connected to a slide 23 that slides with the clamp 1. One of the clamping parts 3 is fixed to the slide 23. By rotating the handle 22, the screw 21 can be rotated, thereby driving the slide 23 to slide along the clamp 1, realizing the movement of the two clamping parts 3 towards or away from each other. For the purpose of operation, both the moving end of the pusher 2 and the other end of the clamping seat 1 are fixed with clamping components 3. The clamping component 3 includes a clamping block 31, and multiple positioning holes 32 are provided on the clamping block 31. Positioning bolts 33 for connection are inserted into the internal threads of the positioning holes 32. The telescopic conductive component 4 is installed in the clamping block 31. The two clamping blocks 31 can achieve the clamping function of the workpiece. The positioning bolts 33 can facilitate the disassembly and assembly of the clamping block 31. A silicone plug 34 is embedded at the top of the positioning hole 32. The silicone plug 34 can seal the positioning hole 32 to prevent electrolyte from entering the positioning hole 32 and corroding the internal components. The clamping component 3 located on the end side of the clamping seat 1 is equipped with a retractable telescopic conductive component 4.
[0023] The telescopic conductive component 4 includes a stepped hole 41 extending through the clamping block 31. A copper rod 42 protruding from the outer wall of the clamping block 31 is inserted into the stepped hole 41. One end of the copper rod 42 contacts the workpiece, and the other end is directly connected to the positive terminal of the power supply, thus achieving the purpose of connecting the workpiece to electricity. A convex ring 43 is fixed on the copper rod 42. A spring seat 44 is threadedly connected to one end of the stepped hole 41 and sleeved on the copper rod 42. A spring 45 is provided between the spring seat 44 and the convex ring 43 and sleeved on the outside of the copper rod 42. The stepped hole 41 enables the sliding installation of the copper rod 42. The spring 45 and the spring seat 44 can be sleeved on the copper rod 42. The copper rod 42, in conjunction with the protruding ring 43, is pre-tightened by the spring 45, ensuring that the end of the copper rod 42 that contacts the workpiece is extended from the outer wall of the clamping block 31. The spring seat 44 is fixed to the stepped hole 41 by a threaded connection. When the workpiece is clamped, the copper rod 42 is subjected to pressure and retracts into the stepped hole 41, compressing the spring 45. This ensures that the copper rod 42 is in close contact with the workpiece and provides electrical conductivity. A guide slot is provided on the copper rod 42, and a directional bolt 5 fixed to the clamping block 31 is inserted into the guide slot. The directional bolt 5 prevents the relative rotation of the copper rod 42 and ensures stable contact with the workpiece.
[0024] The working principle of the conductive device for a planar electrolytic grinding fixture provided by this utility model is as follows: By rotating the handle 22, the screw 21 can be driven to rotate, which in turn drives the slide 23 to slide along the clamp seat 1, driving a clamping block 31 to move towards the clamping block 31 on the clamp seat 1, thereby achieving the purpose of clamping and positioning the workpiece. When the workpiece is clamped, the copper rod 42 is subjected to pressure and retracts into the stepped hole 41, compressing the spring 45. When the workpiece is clamped or released, the copper rod 42 is in close contact with the workpiece, thus achieving the function of conducting electricity.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
