Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and in particular to a positioning fixture for electrode screw connection. Background Technology

[0002] like Figure 1 As shown, one of the assembly procedures for the electrode is to fix stainless steel spring plates to both sides of the brass sheet along the axial direction using nuts and bolts. The current difficulty in this assembly procedure lies in aligning the screw holes of the brass sheet and the stainless steel fin one-to-one, inserting bolts into the screw holes of the brass sheet and the stainless steel fin respectively, and tightening nuts to achieve a fixed connection between the brass sheet and the stainless steel fin. Although this assembly procedure is simple in content, the process of aligning the screw holes and sequentially inserting bolts and tightening nuts is time-consuming, inefficient, and easily causes fatigue and frustration among workers. Based on this, the inventor proposes the technical solution of this application. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a electrode screw-in positioning fixture that can quickly realize the correspondence and fastening connection of the screw holes of brass sheets and stainless steel spring sheets, thereby greatly improving assembly efficiency.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] A electrode screw-in positioning fixture, comprising:

[0006] The first plane has a number of square holes corresponding to the number of brass sheet screw holes for inserting and placing nuts along both sides of the first plane, and a cylindrical hole is opened from the center of the bottom surface of the square hole to allow the shank of the bolt to pass through.

[0007] The second plane is higher than both ends of the first plane to form a step with the first plane. The brass sheet is placed on the first plane and its two ends abut against the side of the second plane that is higher than the first plane.

[0008] To achieve the above technical solution, firstly, a nut is placed in the square hole. Then, a brass sheet is placed on the first plane, with both ends of the brass sheet abutting against the side of the second plane that is higher than the first plane. Next, a stainless steel spring cover with a bolt inserted is placed on the brass sheet. At this time, the shank of the bolt is inserted into the cylindrical hole. Finally, the bolt is tightened to make the bolt and nut threaded together, thus achieving the fixed connection between the brass sheet and the stainless steel spring. The entire assembly process overcomes the cumbersome process of the original one-to-one correspondence, greatly improves work efficiency, and reduces the workload of the staff.

[0009] Furthermore, it also includes a positioning groove on the axial side of the first plane for placing a stainless steel spring, the positioning groove corresponding to the square hole.

[0010] To achieve the above technical solution, the positioning groove facilitates the initial positioning of the stainless steel spring cover when it is fastened to the brass sheet.

[0011] Furthermore, the bottom surface of the positioning groove is provided with a bottom groove for the bottom end of the stainless steel spring to be inserted.

[0012] To achieve the above technical solution, the bottom groove is designed to allow the bottom end of the stainless steel spring to be inserted so that the stainless steel spring and the brass sheet can fit together.

[0013] Furthermore, the width of the two sides of the positioning groove is greater than the width of the stainless steel spring sheet.

[0014] To achieve the above technical solution, the width of both sides of the positioning groove is greater than the width of the stainless steel spring sheet, which makes it easier for the stainless steel spring sheet cover to be fastened to the brass sheet.

[0015] As described above, the electrode screw-in positioning fixture provided by this utility model has the following beneficial effects:

[0016] 1. The electrode screw-connection positioning fixture provided in this application can overcome the most cumbersome multi-part correspondence work in the original assembly process by using a simple structural design, which simplifies the work content, improves work efficiency, and also reduces the workload of the staff.

[0025] Please see Figure 2-3 This utility model provides a screw-on positioning fixture for an electrode 100, including: a first plane 11 and a second plane 12, wherein the second plane 12 is higher than both ends of the first plane 11 and forms a step with the first plane 11, and when the brass sheet 101 is placed on the first plane 11, both ends abut against the side 13 of the second plane 12 that is higher than the first plane 11.

[0026] The first plane 11 has square holes 111 on both sides, corresponding to the screw holes of the brass sheet 101, for inserting and placing nuts 103. A cylindrical hole 112 is opened from the center of the bottom surface of the square hole 111 to allow the shank of the bolt 105 to pass through. During assembly, the nut 103 is first placed into the square hole 111, and then the brass sheet 101 is placed on the first plane 11. At this time, the nut 103 in the square hole 111 corresponds to the screw hole of the brass sheet 101.

[0027] See Figure 3 A positioning groove 131 is provided on the side 13 along the axial side of the first plane 11. The width of the two sides of the positioning groove 131 is greater than the width of the stainless steel spring sheet 102. The positioning groove 131 corresponds one-to-one with the square hole 111. A bottom groove 132 is provided on the bottom surface of the positioning groove 131.

[0028] A bolt 105 with a washer 104 is inserted into the screw hole of the stainless steel spring 102 and fastened to the brass sheet 101 already placed on the first plane 11 according to the initial positioning cover of the positioning groove 131. At the same time, the bottom end of the stainless steel spring 102 is inserted into the bottom groove 132 so that the stainless steel spring 102 and the brass sheet 101 are in contact. At this time, the shank of the bolt 105 is inserted into the cylindrical hole 112. The bolt 105 is tightened to fix the bolt 105 and the nut 103, thus completing the assembly process of the brass sheet 101 and the stainless steel spring 102.

[0029] The electrode 100 screw-in positioning fixture provided in this application has the advantage of overcoming the most cumbersome multi-part correspondence work in the original assembly process by utilizing a simple structural design, simplifying the work content of the staff, reducing the workload of the staff, and at the same time greatly improving work efficiency.
