Description

Technical Field

[0001] This invention relates to the field of product testing technology, and in particular to a testing fixture and processing equipment for production. Background Technology

[0002] In the new energy industry, the safety of lithium batteries has attracted widespread public attention. The last line of defense for the safety of a single battery is the lithium battery cover in the structural components. The lithium battery cover connects the cell pack and the external power system. Once this last line of defense is breached, the safety performance of the battery cannot be guaranteed. Therefore, it is particularly important to conduct scientific testing on the cover. Among them, the torque value parameter of the terminals on the cover is the key to ensuring the ability of the single battery pack to resist external mechanical vibration.

[0003] Currently, most battery manufacturers do not have a standardized testing standard for torque testing, nor a complete set of testing fixtures. The testing methods are also varied. In particular, for the cylindrical terminals on the lithium battery cover, a square aluminum part needs to be welded to the cylindrical terminal before a torque wrench can be used for torque testing, which is cumbersome. Summary of the Invention

[0004] This invention provides a testing fixture and a processing equipment for production, which can solve the problem in the prior art that the operation is relatively cumbersome when performing torque testing on the cylindrical terminals on the lithium battery cover.

[0005] A testing fixture includes a fixing block, flat-jaw pliers, and a torque wrench. The fixing block has a central placement slot on one side, and a lower threaded slot is formed through the bottom of the central placement slot. A lower steel column is threadedly connected to the lower threaded slot. An upper threaded slot is formed on the upper end face of the fixing block, extending into the central placement slot. An upper steel column is threadedly connected to the upper threaded slot. A knob block is fixed to the upper end of the upper steel column. Multiple contact teeth are formed on the opposite surfaces of the upper and lower steel columns.

[0007] As a further technical solution of the present invention, the clamping assembly includes a side groove formed on one side of the lifting seat, and two movable blocks are symmetrically and movably arranged in the side groove. Each movable block has a clamping block fixed on the side near the grinding wheel. The lifting seat is provided with a translation drive mechanism II that works in conjunction with the two movable blocks.

[0008] As a further technical solution of the present invention, the translation drive mechanism II includes a threaded rod rotatably disposed in the side groove, the threaded rod threaded through two moving blocks, an extension column rotatably fixed at one end of the threaded rod, and a handwheel rotatably fixed at one end of the extension column rotatably passing through the lifting seat. Two guide rods rotatably fixed on the inner wall of the side groove are symmetrically fixed, and the guide rods rotatably pass through the two moving blocks.

[0010] As a further technical solution of the present invention, the translation drive mechanism includes two translation slides opened on the upper surface of the worktable, each translation slide has a translation slider slidably arranged in each translation slide, and each translation slide has a lead screw 2 rotatably arranged in each translation slide, the lead screw 2 threaded through the translation slider, the worktable is provided with a drive box 2 for cooperating with the rotation of the lead screw 2, and the translation seat is fixed to the upper surface of the two translation sliders.

[0011] As a further technical solution of the present invention, the debris collection assembly includes a receiving plate movably disposed on one side of the translation seat, a collection box is placed on the upper surface of the receiving plate, a limiting unit for use with the collection box is provided on the receiving plate, and a lifting unit for use with the receiving plate is provided on the translation seat.

[0012] As a further technical solution of the present invention, the lifting unit includes a lifting slide groove opened on one side of the translation seat, a lifting plate is slidably arranged in the lifting slide groove, a plurality of springs are fixed between the upper end surface of the lifting plate and the top of the lifting slide groove, a receiving plate is fixed on one side of the lifting plate, and limit sliders are fixed on both sides of the lifting plate. Limiting slide grooves are symmetrically opened on the inner wall of the lifting slide groove to cooperate with the limit sliders.

[0013] As a further technical solution of the present invention, the limiting unit includes a right fixing plate and a left fixing plate fixed to the upper surface of the receiving plate. An abutment plate is movably provided on the upper surface of the receiving plate. A threaded rod II is rotatably provided on one side of the abutment plate. One end of the threaded rod II is threaded through the left fixing plate and fixed with a handwheel II. Two guide rods II are symmetrically fixed on one side of the abutment plate. Each guide rod II movably passes through the left fixing plate.

[0014] As a further technical solution of the present invention, a mounting plate is detachably provided on one side of the upper surface of the collection box, and a brush layer is fixed on the upper surface of the mounting plate.

[0015] The beneficial effects of this invention are: 1. In the initial state, there is a large gap between the upper and lower steel columns on the fixing block, which facilitates placing the lithium battery cover to be tested between the upper and lower steel columns. Then, rotate the upper steel column to move it downwards and closer to the terminal of the lithium battery cover until the upper and lower steel columns cooperate to clamp and fix the terminal of the lithium battery cover (the upper and lower steel columns act on the upper and lower end faces of the lithium battery cover terminal respectively). During this process, the contact teeth are directly screwed into and fixed to the entire lithium battery cover. Then, the fixing block is clamped and fixed on the flat-jaw pliers. Then, the working end of the torque wrench is placed on the knob block, and the torque can be measured by the torque wrench. It is convenient to use.

[0016] 2. In the initial state, the lifting seat is in a high position, and the translation seat, drive seat, and grinding wheel are positioned away from the vertical mounting frame. This facilitates the placement of the fixed block to be processed onto the clamping assembly. The clamping assembly holds and fixes the fixed block (with the surface to be processed facing the grinding wheel). Then, the lifting drive mechanism causes the lifting seat, along with the clamping assembly and the fixed block, to move downwards until the fixed block is on the translation path of the grinding wheel. The movement then stops. At this point, the translation seat, drive seat, and grinding wheel, under the action of the translation drive mechanism, move towards the vertical mounting frame. The grinding wheel continues until its outer surface adheres to the side wall of the fixed block. Then, the drive box drives the grinding wheel to rotate clockwise, allowing it to grind the side wall of the fixed block. During this process, the lifting drive mechanism causes the lifting seat, along with the clamping assembly and the fixed block, to move up and down repeatedly, working in conjunction with the grinding wheel to grind the side wall of the fixed block. Once the grinding is complete, the grinding wheel stops rotating. Under the action of the translation drive mechanism, the translation seat, drive seat, and grinding wheel move away from the vertical mounting frame again. Then, the lifting drive mechanism causes the lifting seat, along with the clamping assembly and the fixed block, to move upward, facilitating the unloading of the processed fixed block.

[0017] 3. When the grinding wheel grinds the side wall of the fixed block near the lower end, the side wall of the fixed block cannot guide the metal debris generated during grinding downwards. To facilitate the collection of metal debris in this state, the collection box and the receiving plate are positioned at a higher height on the sliding seat, making it easier for the collection box to collect the metal debris generated during grinding. When the fixed block moves downwards, the lower end face of the fixed block is lower than the horizontal height of the center of the grinding wheel. The lower side wall of the fixed block will block the metal debris generated during grinding and guide the metal debris downwards, thus facilitating the metal debris to fall into the collection box. During the downward movement of the fixed block, its lower end face will abut against the upper end face of the collection box. With the cooperation of the lifting unit, the collection box and the receiving plate can move downwards together, avoiding obstruction to the downward movement of the fixed block.

[0018] 4. When the lower end face of the fixing block does not contact the upper end face of the collection box, the collection box and the receiving plate are at a higher position on the sliding seat. At this time, the upper end face of the brush layer abuts against the lower surface of the grinding wheel to clean the grinding debris adhering to the surface of the grinding wheel. When the fixing block presses down on the upper end face of the collection box and moves downward together, the mounting plate and the brush layer also move downward with the collection box. During this process, the brush layer moves away from the surface of the grinding wheel, so that the brush layer will not be in continuous contact with the rotating grinding wheel, thereby extending the service life of the brush layer.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] Reference Figures 1-17A testing fixture includes a fixing block 100, a flat-jaw pliers 500, and a torque wrench 501. The flat-jaw pliers 500 are fixed to an external testing platform. A central placement through groove 101 is provided on one side of the fixing block 100. A lower threaded through groove 103 is provided through the bottom of the central placement through groove 101. A lower steel column 102 is threadedly connected to the lower threaded through groove 103. An upper threaded through groove 104 is provided on the upper end face of the fixing block 100. The upper threaded through groove 104 extends into the central placement through groove 101. An upper steel column 105 is threadedly connected to the upper threaded through groove 104. A knob block 106 is fixed to the upper end of the upper steel column 105. Multiple contact teeth 107 are provided on the opposite surfaces of the upper steel column 105 and the lower steel column 102.

[0023] In use, initially, there is a large gap between the upper steel column 105 and the lower steel column 102 on the fixing block 100, which facilitates placing the lithium battery cover 503 to be tested between the upper steel column 105 and the lower steel column 102. Then, the upper steel column 105 is rotated, causing it to move downwards closer to the terminals of the lithium battery cover 503, until the upper steel column 105 and the lower steel column 102 cooperate to clamp and fix the terminals of the lithium battery cover 503. The upper steel column 105 and the lower steel column 102 act on the upper and lower end faces of the lithium battery cover plate 503 terminals, respectively. During this process, the contact teeth 107 are directly screwed into and fixed to the entire lithium battery cover plate 503. Then, the fixing block 100 is clamped and fixed on the flat-jaw pliers 500 (the method of using the flat-jaw pliers 500 is the prior art). Then, the working end of the torque wrench 501 is sleeved on the knob block 106. Then, the torque can be measured by the torque wrench 501, which is convenient to use.

[0024] Considering the possibility of surface contact between the products, which could lead to significant differences in torque test results, a lower steel column 102 and an upper steel column 105 are provided. Multiple contact teeth 107 are also provided on the opposite surfaces of the lower steel column 102 and the upper steel column 105, thereby changing the surface contact into a line contact.

[0025] A processing equipment for producing inspection tooling, applied to the production and processing of the aforementioned inspection tooling, includes a workbench 200. A vertical mounting frame 221 is fixed to one side of the upper surface of the workbench 200. A lifting seat 201 is movably arranged on one side of the vertical mounting frame 221. A clamping assembly is provided on the lifting seat 201. A translation seat 202 is movably arranged on the other side of the upper surface of the workbench 200. A drive seat 203 is fixed to the upper surface of the translation seat 202. A grinding wheel 204 is rotatably arranged on the drive seat 203. A drive box 205 for use with the grinding wheel 204 is provided on one side of the drive seat 203. The drive box 205 is prior art. A debris collection assembly is provided on the translation seat 202. A translation drive mechanism for use with the translation seat 202 is provided on the workbench 200. A lifting drive mechanism for use with the lifting seat 201 is provided on the vertical mounting frame 221.

[0026] In order to ensure that the fixing block 100 can be placed horizontally on the flat-jaw pliers 500 during use, the lower end surface of the fixing block 100 needs to be ground during production and processing to ensure that the lower end surface of the fixing block 100 is flat enough and free of burrs.

[0027] In the initial state, the lifting seat 201 is in a higher position, and the translation seat 202, drive seat 203, and grinding wheel 204 are located away from the vertical mounting bracket 221. This facilitates the placement of the fixed block 100 to be processed onto the clamping assembly. The clamping assembly clamps and fixes the fixed block 100 (with the surface of the fixed block 100 to be processed facing the grinding wheel 204). Then, the lifting drive mechanism causes the lifting seat 201, along with the clamping assembly and the fixed block 100, to move downwards until the fixed block 100 moves onto the translation path of the grinding wheel 204, and then stops moving. At this time, the translation seat 202, drive seat 203, and grinding wheel 204, under the action of the translation drive mechanism, move towards the vertical mounting bracket 221 until... The outer surface of the grinding wheel 204 is attached to the side wall of the fixed block 100. Then, the drive box 205 drives the grinding wheel 204 to rotate clockwise, so that the grinding wheel 204 can grind the side wall of the fixed block 100. During this process, the lifting drive mechanism causes the lifting seat 201 to move up and down with the clamping component and the fixed block 100, which works with the grinding wheel 204 to grind this side wall of the fixed block 100. When the grinding operation is completed, the grinding wheel 204 stops rotating. The translation seat 202, the drive seat 203 and the grinding wheel 204 move away from the vertical mounting frame 221 again under the action of the translation drive mechanism. Then, the lifting drive mechanism causes the lifting seat 201 to move upward with the clamping component and the fixed block 100, which facilitates the unloading of the processed fixed block 100.

[0028] The clamping assembly includes a side groove 206 opened on one side of the lifting seat 201. Two moving blocks 207 are symmetrically and movably arranged in the side groove 206. Each moving block 207 has a clamping block 208 fixed on the side near the grinding wheel 204. The lifting seat 201 is provided with a translation drive mechanism II that works in conjunction with the two moving blocks 207.

[0029] In the initial state, the two moving blocks 207 are far apart from each other. When the worker places the fixed block 100 to be processed between the two clamping blocks 208, the translation drive mechanism 2 drives the two moving blocks 207 to move closer to each other, thereby bringing the two clamping blocks 208 closer to each other and clamping and fixing the fixed block 100. At this time, the worker can release the fixed block 100.

[0030] The translation drive mechanism 2 includes a threaded rod 209 rotatably disposed in the side groove 206. The threaded rod 209 is threaded through two moving blocks 207. One end of the threaded rod 209 is fixed with an extension column 210. One end of the extension column 210 rotatably passes through the lifting seat 201 and is fixed with a handwheel 211. Two guide rods 212 are symmetrically fixed on the inner wall of the side groove 206. The guide rods 212 movably pass through the two moving blocks 207.

[0031] When the operator rotates the handwheel 211 forward, it causes the extension column 210 and the threaded rod 209 to rotate forward, thereby causing the two moving blocks 207 to move closer to each other.

[0032] When the operator rotates the handwheel 211 in the opposite direction, it causes the extension column 210 and the threaded rod 209 to rotate in the opposite direction, thereby causing the two moving blocks 207 to move away from each other.

[0033] The lifting drive mechanism includes a side slide groove 213 on one side of the vertical mounting frame 221. A lifting slider 214 is movably disposed in the side slide groove 213. One side of the lifting slider 214 is fixedly connected to the lifting seat 201. A lead screw 215 is rotatably disposed in the side slide groove 213. The lead screw 215 is threaded through the lifting slider 214. A working motor 216 for rotating with the lead screw 215 is fixed on the upper end face of the vertical mounting frame 221. Limit sliders 217 are fixed on both sides of the lifting slider 214. Two limit slide grooves are symmetrically provided on the inner wall of the side slide groove 213 for use with the limit sliders 217.

[0034] When the lifting seat 201 needs to move downward, the working motor 216 drives the lead screw 215 to rotate in the forward direction, thereby causing the lifting slider 214 to move downward, which in turn drives the lifting seat 201 to move downward.

[0035] When the lifting seat 201 needs to move upward, the working motor 216 drives the lead screw 215 to rotate in the opposite direction, so that the lifting slider 214 moves upward, thereby driving the lifting seat 201 to move upward.

[0036] The translation drive mechanism includes two translation slides 218 formed on the upper surface of the worktable 200. Each translation slide 218 has a translation slider 219 slidably disposed therein, and each translation slide 218 has a lead screw 220 rotatably disposed therein. The lead screw 220 is threaded through the translation slider 219. The worktable 200 is provided with a drive box 2 that is used to rotate in conjunction with the lead screw 220. The drive box 2 is existing technology. The translation seat 202 is fixed to the upper surface of the two translation sliders 219.

[0037] When the translation seat 202 needs to move toward the direction of the vertical mounting bracket 221, the second drive box drives the second drive screw 220 to rotate in the forward direction, thereby driving the translation slider 219 to move toward the direction of the vertical mounting bracket 221, thereby moving the drive seat 203 and the grinding wheel 204 toward the fixed block 100 to be processed.

[0038] The debris collection assembly includes a receiving plate 300 movably disposed on one side of the translation seat 202, a collection box 301 placed on the upper surface of the receiving plate 300, a limiting unit for use with the collection box 301 provided on the receiving plate 300, and a lifting unit for use with the receiving plate 300 provided on the translation seat 202.

[0039] When the grinding wheel 204 grinds the side wall of the fixed block 100 near its lower end, the side wall of the fixed block 100 cannot guide the metal debris generated during grinding downwards. To facilitate the collection of metal debris in this state, the collection box 301 and the receiving plate 300 are positioned at a higher height on the translation seat 202, making it easier for the collection box 301 to collect the metal debris generated during grinding. When the fixed block 100 moves downwards, its lower end face is lower than the horizontal height of the center of the grinding wheel 204. The lower side wall of the fixed block 100 will block the metal debris generated during grinding and guide it downwards, thus facilitating the metal debris to fall into the collection box 301. During the downward movement of the fixed block 100, its lower end face will abut against the upper end face of the collection box 301. With the cooperation of the lifting unit, the collection box 301 and the receiving plate 300 can move downwards together, avoiding obstruction to the downward movement of the fixed block 100.

[0040] The lifting unit includes a lifting slide 302 opened on one side of the translation seat 202. A lifting plate 303 is slidably arranged in the lifting slide 302. Multiple springs 304 are fixed between the upper end face of the lifting plate 303 and the top of the lifting slide 302. A receiving plate 300 is fixed to one side of the lifting plate 303. Limiting sliders 305 are fixed on both sides of the lifting plate 303. Limiting slides 2 are symmetrically opened on the inner wall of the lifting slide 302 to cooperate with the limiting sliders 2 305.

[0041] In the initial state, the lifting plate 303 is at a higher position in the lifting slide 302, which in turn causes the receiving plate 300 and the collection box 301 to also be at a higher position. As the fixing block 100 continues to move downward, the lower end face of the fixing block 100 will abut against the upper end face of the collection box 301, moving the collection box 301, the receiving plate 300 and the lifting plate 303 downward together. During this process, the spring 304 is stretched and deformed, storing elastic potential energy. After the surface to be processed of the fixing block 100 is polished, the fixing block 100 moves upward with the lifting seat 201. During this process, the spring 304 slowly recovers its deformation, causing the lifting plate 303, the receiving plate 300 and the collection box 301 to move upward.

[0042] The limiting unit includes a right fixing plate 306 and a left fixing plate 307 fixed to the upper end face of the receiving plate 300. A contact plate 308 is movably provided on the upper end face of the receiving plate 300. A threaded rod 309 is rotatably provided on one side of the contact plate 308. One end of the threaded rod 309 is threaded through the left fixing plate 307 and a handwheel 310 is fixed thereon. Two guide rods 311 are symmetrically fixed on one side of the contact plate 308. Each guide rod 311 movably passes through the left fixing plate 307.

[0043] When installing and assembling the collection box 301 and the receiving plate 300, the contact plate 308 is positioned away from the right-side fixing plate 306. Then, the worker places the empty collection box 301 between the contact plate 308 and the right-side fixing plate 306, and rotates the second handwheel 310 in the forward direction, thereby driving the second threaded rod 309 to rotate in the forward direction. This causes the second threaded rod 309 and the contact plate 308 to move towards the collection box 301 until the contact plate 308 is tightly pressed against the outer wall of the collection box 301, thus limiting and fixing the collection box 301.

[0044] A mounting plate 400 is detachably installed on one side of the upper surface of the collection box 301, and a brush layer 401 is fixed on the upper surface of the mounting plate 400.

[0045] When the lower end face of the fixing block 100 is not in contact with the upper end face of the collection box 301, the collection box 301 and the receiving plate 300 are at a higher position on the translation seat 202. At this time, the upper end face of the brush layer 401 abuts against the lower surface of the grinding wheel 204 to clean the grinding debris adhering to the surface of the grinding wheel 204. When the fixing block 100 presses down on the upper end face of the collection box 301 and moves downward together, the mounting plate 400 and the brush layer 401 also move downward together with the collection box 301. During this process, the brush layer 401 moves away from the surface of the grinding wheel 204, so that the brush layer 401 will not be in continuous contact with the rotating grinding wheel 204, thereby extending the service life of the brush layer 401.

[0046] The mounting plate 400 and the collection box 301 can be installed with bolts, and the specific installation method is not limited.

[0047] In use, in the initial state, there is a large gap between the upper steel column 105 and the lower steel column 102 on the fixing block 100, which facilitates placing the lithium battery cover plate 503 to be tested between the upper steel column 105 and the lower steel column 102. Then, the upper steel column 105 is rotated, causing it to move downwards and closer to the terminals of the lithium battery cover plate 503, until the upper steel column 105 and the lower steel column 102 cooperate to clamp the terminals of the lithium battery cover plate 503. The upper steel column 105 and the lower steel column 102 act on the upper and lower end faces of the terminals of the lithium battery cover plate 503, respectively. During this process, the contact teeth 107 are directly screwed into and fixed to the entire lithium battery cover plate 503. Then, the fixing block 100 is clamped and fixed on the flat-jaw pliers 500 (the method of using the flat-jaw pliers 500 is the prior art). Then, the working end of the torque wrench 501 is sleeved on the knob block 106. Then, the torque can be measured by the torque wrench 501, which is convenient to use.

[0048] During the production and processing of the fixed block 100, when the lower end face of the fixed block 100 needs to be ground, the fixed block 100 to be processed is clamped and fixed by the clamping assembly (with the surface of the fixed block 100 to be processed facing the grinding wheel 204). Then, the lifting drive mechanism causes the lifting seat 201 to move downward with the clamping assembly and the fixed block 100 until the fixed block 100 moves into the translation path of the grinding wheel 204, and then stops moving. At this time, the translation seat 202, the drive seat 203 and the grinding wheel 204 move towards the vertical mounting bracket 221 under the action of the translation drive mechanism until the outer surface of the grinding wheel 204 is in contact with the side wall of the fixed block 100. Then, the drive box 205 drives the grinding wheel 204 to rotate clockwise, so that the grinding wheel 204 can grind the side wall of the fixed block 100. During this process, the lifting drive mechanism causes the lifting seat 201 to move up and down with the clamping component and the fixed block 100, and to grind the side wall of the fixed block 100 with the grinding wheel 204. When the grinding operation is completed, the grinding wheel 204 stops rotating. The translation seat 202, the drive seat 203 and the grinding wheel 204 move away from the vertical mounting frame 221 again under the action of the translation drive mechanism. Then, the lifting drive mechanism causes the lifting seat 201 to move upward with the clamping component and the fixed block 100, so as to facilitate the unloading of the processed fixed block 100. When the grinding wheel 204 grinds the side wall of the fixed block 100 near the lower end, the side wall of the fixed block 100 cannot guide the metal debris generated during grinding downwards. In order to facilitate the collection of metal debris in this state, the collection box 301 and the receiving plate 300 are at a higher position on the translation seat 202, so that the collection box 301 can collect the metal debris generated during grinding. When the fixed block 100 moves downwards, the lower end face of the fixed block 100 is lower than the horizontal height of the center of the grinding wheel 204. The lower side wall of the fixed block 100 will block the metal debris generated during grinding and guide the metal debris downwards, so that the metal debris generated during grinding can fall into the collection box 301. During the downward movement of the fixed block 100, its lower end face will abut against the upper end face of the collection box 301. With the cooperation of the lifting unit, the collection box 301 and the receiving plate 300 can move downwards together, avoiding obstruction to the downward movement of the fixed block 100. When the lower end face of the fixing block 100 is not in contact with the upper end face of the collection box 301, the collection box 301 and the receiving plate 300 are at a higher position on the translation seat 202. At this time, the upper end face of the brush layer 401 abuts against the lower surface of the grinding wheel 204 to clean the grinding debris adhering to the surface of the grinding wheel 204. When the fixing block 100 presses down on the upper end face of the collection box 301 and moves downward together, the mounting plate 400 and the brush layer 401 also move downward together with the collection box 301. During this process, the brush layer 401 moves away from the surface of the grinding wheel 204, so that the brush layer 401 will not be in continuous contact with the rotating grinding wheel 204, thereby extending the service life of the brush layer 401.
