[0032] The cross-section of the base plate 1 is circular; the clamping piece 31, the first limiting pin 21 and the second limiting pin 22 are located on the same radius of the base plate 1; the first limiting pin 21 is located between the second limiting pin 22 and the clamping piece 31; the second limiting pin 22 is close to the center of the circle of the base plate 1; the clamping piece 31 is close to the edge of the base plate 1; the clamping piece 31 is located above the first limiting pin 21 and the second limiting pin 22; the clamping piece 31 can clamp the top plane of the coupling in the vertical direction.

[0033] When using the tooling for machining the coupling in the high-voltage switch provided in Example 1 of the utility model, the base plate 1 is fixed to the worktable of the vertical boring machine, so that the center of the base plate 1 coincides with the center of the spindle of the vertical boring machine, and a boring cutter with a large head diameter and a small shank diameter is used. This tooling can be applied to a vertical boring machine disclosed in the Chinese patent application No. 201720362533.3;

[0034] After the base plate 1 is fixed to the workbench of the vertical boring machine, the two first circular holes 03 of the coupling are matched with the first limiting pin 21 and the second limiting pin 22 respectively, so that the lower surface of the base 01 of the coupling contacts the upper plate surface of the base plate 1, and the horizontal movement of the coupling is constrained by the first limiting pin 21 and the second limiting pin 22; the pressing member 31 applies pressure in the direction of the base plate 1 to press the top plane of the fixing member 02 of the coupling, and the vertical movement of the coupling is constrained by the pressing member 31;

[0035] Lower the bottom end of the boring tool head to the level with the upper surface of the base 01 of the coupling, rotate the spindle of the vertical boring machine, drive the boring tool installed on the spindle to rotate, and bore the arc surface on the front end face or the rear end face of the fixing part 02 on the coupling; when the arc surface processing on the front end face or the rear end face of the fixing part 02 on the coupling is completed, remove the clamping part 31, turn the coupling 180°, and then clamp the coupling with the clamping part 31 again, and bore the arc surface on the other end face of the fixing part 02 on the coupling.

[0036] The tooling for processing the coupling in the high-voltage switch provided in Example 1 of the utility model comprises a base plate 1, a first limiting nail 21, a second limiting nail 22 and a clamping member 31; the first limiting nail 21 and the second limiting nail 22 are fixed to the upper plate surface of the base plate 1, and the two first circular holes 03 of the coupling are respectively matched with the first limiting nail 21 and the second limiting nail 22, so that the lower surface of the base 01 of the coupling is in contact with the upper plate surface of the base plate 1, and the horizontal movement of the coupling is constrained by the first limiting nail 21 and the second limiting nail 22; and the clamping member 31 applies pressure in the direction of the base plate 1 to clamp the coupling. The top plane of the fixing member 02, the vertical movement of the coupling is constrained by the clamping member 31; the coupling is subjected to uniform force in the horizontal and vertical directions, so that the coupling and the base plate 1 are relatively fixed, and the base plate 1 is fixed on the workbench of the vertical boring machine, which effectively solves the problem that when processing the arc surface of the groove 05 on the coupling for high-voltage switches, the accuracy of the arc surface of the groove 05 on the coupling cannot be affected due to the inability to fix the coupling and the lathe relatively. When processing the coupling for high-voltage switches, the coupling is stably fixed relative to the lathe, thereby improving the accuracy of the arc surface of the groove 05 on the coupling.

[0037] The tooling for processing the coupling in the high-voltage switch provided in Example 1 of the utility model has a circular cross-section of the base plate 1, and the clamping piece 31, the first limit pin 21 and the second limit pin 22 are located on the same radius of the base plate 1, so that the center of the base plate 1 coincides with the center of the main shaft of the vertical boring machine. When it is necessary to bore the arc surface on the front end face or the rear end face of the fixing piece 02 on the coupling, the other end of the base plate 1 relative to the clamping piece 31 is unobstructed, so that the boring tool on the vertical boring machine can be easily lowered to the position where the coupling needs to be processed, and the center of the base plate 1 coincides with the center of the main shaft of the vertical boring machine. The boring tool can directly process the coupling fixed on the base plate 1, reducing the time cost of positioning the boring tool to the required processing position of the coupling, improving the efficiency of the coupling processing, and at the same time improving the accuracy of the arc surface of the groove 05 on the coupling.

[0038] like Figures 1-2 As shown, in the tooling for machining the coupling in the high-voltage switch provided in Example 1 of the utility model, preferably, in order to make the coupling more stably fixed on the base plate 1, it is necessary to increase the force points between the coupling and the tooling fixture, so that when the boring tool bores the coupling, the force on the coupling is more stable, and the influence of the force applied by the boring tool on the coupling is reduced; to this end, the clamping member 31 includes a base plate 311, a first clamping block 312 and a second clamping block 313, and the direction of the first limiting pin 21 relative to the second limiting pin 22 is taken as the rear, the base plate 311 is horizontally arranged, the first clamping block 312 is vertically fixed to the front end of the base plate 311, the upper surface of the first clamping block 312 is higher than the upper plate surface of the base plate 311, and the lower surface of the first clamping block 312 is flush with the lower plate surface of the base plate 311, and the second clamping block 313 is horizontally fixed to the front end of the first clamping block 312, and the upper surface of the second clamping block 313 is flush with the upper plate surface of the first clamping block 312 The surfaces are flush, and the lower surface of the second clamping block 313 is higher than the lower surface of the first clamping block 312, so that the angle formed by the first clamping block 312 and the second clamping block 313 is a right angle; when the lower surface of the second clamping block 313 presses the top plane of the coupling in the vertical direction, the front end face of the first clamping block 312 contacts the front end face or the rear end face of the fixing part 02 in the coupling. At this time, if the boring tool is boring the arc surface on the front end face of the fixing part 02 in the coupling, it will give the coupling a force in the direction of the first clamping block 312, and the front end face of the first clamping block 312 contacts the rear end face of the fixing part 02 in the coupling, which can give the coupling a reaction force in the direction of the boring tool, thereby maintaining the force stability of the coupling, so that the coupling can be more stably fixed on the base plate 1, avoiding the problem of inaccurate arc surface processing accuracy due to coupling shaking, and improving the accuracy of the arc surface of the groove 05 on the coupling.

[0039] like Figures 1-2As shown, the tooling for processing the coupling in the high-voltage switch provided by Example 1 of the utility model, preferably, in order to support the clamping piece 31 and enable the clamping piece 31 to apply force to the bottom plate 1 in the vertical direction, so that the coupling is fully stressed in the vertical reverse direction, the second limiting assembly 3 also includes a supporting bolt 32 for supporting the clamping piece 31 and a limiting bolt 33 for limiting the displacement direction of the clamping piece 31 on the horizontal plane; the limiting bolt 33, the supporting bolt 32, the first limiting nail 21 and the second limiting nail 22 are located on the same straight line, and the supporting bolt 32 is located on the same straight line. The support bolt 32 is closer to the center of the bottom plate 1 than the limiting bolt 33. The limiting bolt 33 is located below the base plate 311. When the coupling is placed on the bottom plate 1 and the first limiting nail 21 and the second limiting nail 22 are respectively inserted into the first circular hole 03 on the coupling, the base plate 311 is located on the limiting bolt 33, and the first clamping block 312 and the second clamping block 313 fixed to the base plate 311 act on the coupling together to keep the base plate 311 in a horizontal state, so that the base plate 311 can apply force toward the bottom plate 1, thereby clamping the coupling in the vertical direction.

[0040] In order to adjust the height of the limit bolt 33 so that the base plate 311 can maintain a horizontal state when it is located on the top plane of the limit bolt 33 and the coupling, a first screw hole 11 matching the limit bolt 33 is opened on the bottom plate 1, and the limit bolt 33 is rotatably fixed to the first screw hole 11; similarly, in order to adjust the height of the support bolt 32, a second screw hole 12 matching the support bolt 32 is opened on the bottom plate 1, and the support bolt 32 is rotatably fixed to the second screw hole 12;

[0041] The base plate 311 is provided with a fixing hole 3111 for the support bolt 32 to pass through. The diameter of the head of the support bolt 32 is larger than the diameter of the fixing hole 3111. The support bolt 32 passes through the fixing hole 3111 so that the support bolt 32 is sleeved in the base plate 311. A spring 321 is arranged on the periphery of the support bolt 32. The spring 321 is located below the base plate 311. When there is no coupling on the other side except the limiting bolt 33, the spring 321 can prop up the base plate 311 so that the base plate 311 and the bottom plate 1 always maintain a relatively parallel state, which is convenient for installing the coupling to be processed on the bottom plate 1, thereby improving the efficiency of the coupling processing; further, when the base plate 311 is located on the limiting bolt 33 and the first clamping block 312 and the second clamping block 313 are in contact with the coupling, the support bolt 32 is tightened downward, and the head of the support bolt 32 is in contact with the base plate 311, thereby forming a downward pressure, so that the second clamping block 313 relatively fixed to the base plate 311 can clamp the coupling through the bottom plate 1;

[0042] In order to limit the rotation of the substrate 311 on the horizontal plane, a frame 3112 is provided on the bottom edge of the substrate 311, and the limiting bolt 33 can be partially located in the frame 3112 area, so that the top of the limiting bolt 33 can clamp the frame 3112 to prevent the substrate 311 from rotating on the horizontal plane, thereby preventing the coupling from rotating at an angle on the horizontal plane when the boring tool applies force, affecting the arc surface of the coupling processed by the boring tool, thereby improving the processing accuracy of the arc surface of the groove 05 on the coupling.

[0043] like Figures 1-2 As shown, the tooling for processing the coupling in the high-voltage switch provided by Example 1 of the utility model, preferably, in order to make the supporting bolt 32 and the limiting bolt 33 more stably rotatably fixed on the base plate 1, a limiting nut 13 is fixed above the first screw hole 11, and a supporting nut 14 is fixed above the second screw hole 12, the screw hole diameter of the limiting nut 13 is the same as the diameter of the first screw hole 11, the center of the screw hole of the limiting nut 13 coincides with the center of the first screw hole 11, the screw hole diameter of the supporting nut 14 is the same as the diameter of the second screw hole 12, the center of the screw hole of the supporting nut 14 coincides with the center of the second screw hole 12, the screw rod of the limiting bolt 33 is rotatably fixed in the limiting nut 13, the screw rod of the supporting bolt 32 is rotatably fixed in the supporting nut 14, and the limiting nut 1 The height adjustment space of the limit bolt 33 is increased, and the height adjustment space of the support nut 14 is increased, so as to adapt to the processing of the upper arc surface of the coupling of different sizes, and the limit nut 13 can facilitate the installation and disassembly of the limit bolt 33, and the support nut 14 can facilitate the installation and disassembly of the support bolt 32, which is conducive to the storage of the tooling; the spring 321 is located above the support nut 13, and the cross section of the support nut 13 is larger than the cross section of each circle of the spring 321. The center of the support nut 13 coincides with the center of each circle of the spring 321, so that the spring 321 will not slide off the top of the support nut 13, so that the spring 321 can stably support the base plate 311 and maintain a relatively stable state with the bottom plate 1, which is convenient for loading and unloading the coupling to be processed on the tooling.

[0044] like Figure 2As shown, the tooling for machining the coupling in the high-voltage switch provided by Example 1 of the utility model is preferably provided with a first clip 322 between the spring 321 and the base plate 311 in order to maintain the spring 321 and the base plate 311 and to improve the service life of the tooling. The cross section of the first clip 322 is larger than the cross section of each coil of the spring 321. The support bolt 32 is sleeved in the first clip 322. The base plate 311 can transmit the support force of the spring 321 to the base plate 311 through the first clip 322, so that the base plate 311 can be completely supported by the spring 321. 1; in order to maintain the support bolt 32 and the base plate 311 and improve the service life of the tooling, a second clamping piece 323 is arranged between the head of the support bolt 32 and the base plate 311, and the support bolt 32 is sleeved in the second clamping piece 323. The second clamping piece 323 avoids direct friction contact between the head of the support bolt 32 and the upper plate surface of the base plate 311. At the same time, the base plate 311 can transfer the pressure generated when tightening the support bolt 32 to the base plate 311 through the second clamping piece 323, so that the base plate 311 can be completely subjected to the pressure from the support bolt 32.

[0045] like Figures 1 to 3 As shown, the tooling for processing the coupling in the high-voltage switch provided in Example 1 of the utility model, preferably, in order to facilitate the adjustment of the height of the limit bolt 33, when the coupling is processed, the base plate 311 is maintained in a horizontal state, and further, the fixing hole 3111 is made into a waist hole, and the support bolt 32 passes through the fixing hole 3111 and is rotated and fixed in the second screw hole 12, and the fixing hole 3111 is opened in the front-to-back direction, and the base plate 311 can be displaced forward and backward along the direction of the straight line where the first limit pin 21 and the second limit pin 22 are located. When the first limit pin 21 and the second limit pin 22 are respectively inserted into the two first circular holes 03 on the coupling, the position of the base plate 311 can be continuously adjusted, and the height state of the limit bolt 33 can be judged from the right angle formed by the first clamping block 312 and the second clamping block 313 and the contact angle of the coupling, and then the height of the limit bolt 33 can be adjusted to keep the base plate 311 in a horizontal state. The cam 311 is provided with a plurality of projections on the top of the base plate 312, and the projections on the bottom of the base plate 312 are provided with projections on the top of the base plate 312.
