[0001] The utility model relates to the technical field of polytetrafluoroethylene guide ring processing, in particular to a PTFE guide ring cutting tooling fixture. Background Technique

[0002] A PTFE guide ring is a component made of polytetrafluoroethylene material. The polytetrafluoroethylene guide ring is a key component commonly used between the metal guide rod and the metal contact seat inside the GIS high-voltage switch, which plays the roles of installation guidance, buffering and wear resistance, and insulation protection.

[0003] When the polytetrafluoroethylene guide ring is installed inside the metal contact seat, a cutter is needed to cut a certain width to facilitate insertion.

[0025] Please refer to Figures 1-8 , a PTFE guide ring cutting tooling, including a bottom plate 1, an adjusting mechanism 2 and a positioning mechanism 3 are arranged on the top of the bottom plate 1, and a driving mechanism 4 is arranged on one side of the adjusting mechanism 2;

[0026] The adjusting mechanism 2 can quickly adjust the cutting width of the guide ring and can store multiple common cutting widths. The positioning mechanism 3 is used to fix the guide ring, and the driving mechanism 4 drives the internal components of the adjusting mechanism 2 to rotate at a fixed angle.

[0027] The adjusting mechanism 2 includes a first bracket 201, the first bracket 201 is fixedly connected to the top of the bottom plate 1, a first cylinder 202 is fixed on the top of the first bracket 201, one end of the first cylinder 202 penetrates through the first bracket 201 and is fixed with an installation shell 203, a fixed blade 204 is fixed at the bottom of the installation shell 203, a movable blade 205 is arranged on one side of the fixed blade 204, the movable blade 205 is slidably connected to the inner wall of the installation shell 203, two slide bars 207 are fixed on the surface of the movable blade 205, two U-shaped frames 206 are fixed on the surface of the installation shell 203, a reset structure is installed on the surface of the slide bar 207, the slide bar 207 slidably penetrates through the installation shell 203 and the U-shaped frame 206, a second cylinder 210 is fixed on the surface of the installation shell 203, the number of the second cylinders 210 is two, one end of the second cylinder 210 penetrates through the installation shell 203 and is fixed with a connecting frame 211, two side plates 212 are fixed on the surface of the connecting frame 211, a transmission shaft 213 is rotatably connected to the surface of the side plate 212, two mounting plates 214 are fixed on the surface of the transmission shaft 213, a plurality of grooves 215 are formed on the surface of the mounting plate 214, cushion blocks 218 are detachably arranged on the surface of the grooves 215, and a limiting structure is arranged inside the grooves 215;

[0028] When the first cylinder 202 starts, it can adjust the height position of the mounting shell 203, and can also cut the guide ring with the fixed blade 204 and the movable blade 205. When it is necessary to adjust the cutting width, first start the second cylinder 210 to drive the connecting frame 211 to drive the side plate 212 to move downward, and take out the spacer block 218 from the inside of the movable blade 205 and the fixed blade 204. The movable blade 205 can be reset to fit the surface of the fixed blade 204 through the reset structure. Then, the drive mechanism 4 can be used to rotate the transmission shaft 213 at a fixed angle, so that the positions of different spacer blocks 218 can be exchanged. The spacer block 218 can be fixed or unfixed through the limiting structure, so as to replace the spacer blocks 218 with different thicknesses and achieve the storage effect of the predetermined cutting width. After rotating the spacer block 218 with the required thickness vertically upward, the second cylinder 210 resets and drives the baffle 208 to move upward, so that the baffle 208 can push open the movable blade 205 and enter between the movable blade 205 and the fixed blade 204, thereby realizing the rapid adjustment of the distance between the movable blade 205 and the fixed blade 204 and achieving the rapid adjustment effect of the cutting width, improving the processing efficiency.

[0029] Further, the reset structure on the surface of the sliding rod 207 includes a baffle 208, the baffle 208 is fixedly connected to the surface of the sliding rod 207, and a spring 209 is fixedly arranged on the surface of the baffle 208, and one end of the spring 209 is fixedly connected to the inner wall of the U-shaped frame 206;

[0030] After the spacer block 218 enters the inside of the movable blade 205 and the fixed blade 204, the movable blade 205 will drive the sliding rod 207 to move towards the direction of the U-shaped frame 206, so that the baffle 208 approaches the inner wall of the U-shaped frame 206 and compresses the spring 209. When the spacer block 218 is taken out from the inside of the movable blade 205 and the fixed blade 204, the spring 209 can rebound, so that the movable blade 205 can move back to fit the surface of the fixed blade 204.

[0031] Further, the limiting structure inside the groove 215 includes a positioning plate 216, the positioning plate 216 is fixedly connected to the surface of the groove 215, and a first screw rod 217 is threadedly penetrated through the surface of the positioning plate 216, and a limiting plate 222 is fixed to one end of the first screw rod 217;

[0032] After the spacer block 218 is placed inside the groove 215, the first screw rod 217 can be rotated so that the limiting plate 222 can move towards the surface of the spacer block 218, so that the spacer block 218 can be clamped and fixed, and the fixation can be released by rotating the first screw rod 217, so as to facilitate the replacement of the spacer blocks 218 with different thicknesses.

[0033] Further, two first guide rods 219 penetrate through the surface of the positioning plate 216. One end of each first guide rod 219 is fixedly connected to the surface of the limiting plate 222, and a card slot for cooperating with the limiting plate 222 is formed on the surface of the cushion block 218.

[0034] The first guide rods 219 can provide a linear guiding effect for the positioning plate 216 to prevent the positioning plate 216 from shifting. The design of the card slot enables the limiting plate 222 to enter the card slot on the surface of the cushion block 218, making the limiting effect on the cushion block 218 better.

[0035] Further, the positioning mechanism 3 includes a second bracket 301. An adjusting shell 302 is fixed to the top of the second bracket 301. A cutting groove 303 is formed on the surface of the second bracket 301. A bidirectional lead screw 304 is rotatably connected to the inner wall of the adjusting shell 302. Two sliding sleeves 305 are threadedly connected to the surface of the bidirectional lead screw 304. A chute 307 is formed on the surface of the bidirectional lead screw 304. The sliding sleeves 305 are slidably connected to the surface of the chute 307. A first clamping plate 306 is fixed to the surface of the sliding sleeves 305. One end of the bidirectional lead screw 304 penetrates through the adjusting shell 302 and is fixed with a hand wheel.

[0036] The guiding ring can be placed on the surface of the second bracket 301. Due to the design of the cutting groove 303, the fixed blade 204 and the movable blade 205 can pass through the guiding ring and fit with the surface of the cutting groove 303. When the bidirectional lead screw 304 is rotated through the hand wheel, the two sliding sleeves 305 will move towards each other or in the opposite direction under the influence of the thread, and the first clamping plate 306 can move together with the sliding sleeves 305, enabling the first clamping plate 306 to clamp and fix the guiding ring to prevent the guiding ring from shifting during the cutting process.

[0037] Further, a top plate 308 is fixed to the top of the adjusting shell 302. A second screw rod 309 threadedly penetrates through the surface of the top plate 308, and a second clamping plate 310 is fixed to the bottom of the second screw rod 309.

[0038] After the guiding ring is placed between the two first clamping plates 306, by rotating the second screw rod 309, the second clamping plate 310 can move downward, so that the second clamping plate 310 can clamp and fix the top of the guiding ring, further improving the limiting effect on the guiding ring.

[0039] Further, the driving mechanism 4 includes a reduction motor 401. The reduction motor 401 is fixedly connected to the surface of one side side plate 212. The output shaft of the reduction motor 401 penetrates through the side plate 212 and is fixed with a driving disc 402. A positioning disc 403 and a push rod 404 are fixed to the surface of the driving disc 402. A driven disc 405 is fixed to the surface of the transmission shaft 213. The driven disc 405 is slidably connected to the surface of the positioning disc 403. A plurality of driving grooves 406 are formed on the surface of the driven disc 405.

[0040] When the reduction motor 401 starts, it can drive the driving disk 402 to rotate. When the driving disk 402 rotates, it will drive the positioning disk 403 to move together on the surface of the driven disk 405. When the surface of the positioning disk 403 no longer contacts the surface of the driven disk 405, the push rod 404 will be able to enter the inside of the driving groove 406, so that the driving groove 406 can drive the driven disk 405 to rotate, so that the driven disk 405 can obtain a fixed-angle rotation effect, thereby realizing that the driven disk 405 drives the transmission shaft 213 to rotate at a fixed angle.

[0041] Furthermore, guiding plates 220 are fixed to the bottoms of the movable blade 205 and the fixed blade 204. The guiding plates 220 are designed in an inclined structure. One end of the surface of the cushion block 218 is designed in a semi-circular structure. Two second guide rods 221 penetrate through the surface of the first bracket 201. The bottoms of the second guide rods 221 are fixedly connected to the top of the mounting shell 203.

[0042] Through the design of the guiding plates 220 and the cushion block 218, when the cushion block 218 moves upward, the cooperation between the semi-circular structure at its top and the inclined guiding plate 220 can make it easier for the cushion block 218 to enter between the two guiding plates 220, so that the cushion block 218 can normally enter between the fixed blade 204 and the movable blade 205. When the mounting shell 203 moves, the second guide rods 221 can slide on the surface of the first bracket 201, so that the mounting shell 203 can obtain a guiding effect.

[0043] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
