Description
Technical Field
[0001] This invention relates to the field of testing fixture technology, and in particular to a battery cover plate terminal torque testing fixture and its processing equipment. Background Technology
[0002] The cover plate and terminals of new energy batteries (especially lithium-ion power batteries) are the core components connecting the internal cells of the battery with the external circuit. Their torque performance directly affects the battery's sealing performance (the insulating sealing ring between the terminal and the cover plate needs to be kept in a compressed state under a specific torque to prevent electrolyte leakage) and electrical reliability (loosening of the terminal threaded connection will lead to increased contact resistance, causing overheating or even fire).
[0003] During the production and R&D process of new energy battery covers, it is necessary to conduct torque tests on the terminals of the battery cover. When existing testing equipment performs torque tests, the smooth surface of the terminals is prone to circumferential slippage during the test, which affects the accuracy of the test results. Summary of the Invention

[0010] As a further technical solution of the present invention, the clamping mechanism includes a placement seat fixed to the upper surface of the workbench, a positioning block and a fixing seat fixed to the upper surface of the placement seat, an abutment block movably disposed between the positioning block and the fixing seat, a lead screw rotatably disposed on one side of the abutment block, one end of the lead screw threaded through the fixing seat and fixed with a handwheel, two guide posts 1 fixed to one side of the abutment block, each guide post 1 movably passing through the fixing seat, and a U-shaped protective cover fixed to the side wall of the abutment block.
[0011] As a further technical solution of the present invention, a movable seat is movably provided on the upper end surface of the workbench, a recessed groove is opened on the upper end surface of the movable seat, an electric push rod is fixed in the recessed groove, a lifting plate is fixed at the end of the telescopic end of the electric push rod, an air blowing hood is fixed on the upper end surface of the lifting plate, an air pump is provided on one side of the workbench, a telescopic hose is provided between the air outlet end of the air pump and the air blowing hood, a translation mechanism I is provided on the workbench to cooperate with the movable seat, a waste collection assembly is provided on the workbench, a U-shaped baffle is fixed on the upper end surface of the workbench, and two guide posts II are symmetrically fixed on the lower end surface of the lifting plate, each guide post II movably penetrating into the movable seat.
[0012] As a further technical solution of the present invention, the waste collection assembly includes a discharge trough opened on the upper surface of the workbench, a side passage trough extending through the discharge trough on one side of the workbench, a collection frame placed in the side passage trough, and a guide plate fixed at an inclination in the discharge trough.
[0013] As a further technical solution of the present invention, the translation mechanism includes a sliding groove on the upper surface of the worktable, a sliding block is slidably disposed in the sliding groove, a drive unit is disposed in the sliding groove to cooperate with the sliding block, and a moving seat is fixed to the upper surface of the sliding block.
[0014] As a further technical solution of the present invention, the translation mechanism 2 includes a sliding groove 2 opened on the upper surface of the worktable, a sliding block 2 slidably disposed in the sliding groove 2, a drive unit 2 used in conjunction with the sliding block 2 disposed in the sliding groove 2, and a multi-axis robotic arm fixed to the upper surface of the sliding block 2.
[0015] The beneficial effects of this invention are: 1. In use, the operator can manually push the upper T-shaped pressure block upwards, then insert the end of the battery cover body with the terminal body into the U-shaped block. After releasing the upper T-shaped pressure block, the upper conical protrusion at the lower end of the upper T-shaped pressure block presses against the upper surface of the terminal body. At this time, the lower surface of the terminal body contacts the multiple lower conical protrusions on the lower T-shaped pressure block. Then, the locking screw is rotated and tightened. During this process, the locking screw will move downwards relative to the U-shaped block until the lower end of the locking screw abuts against the upper T-shaped pressure block. The pressure blocks move downwards together, causing the upper conical protrusion to engage with the lower conical protrusion to lock the terminal body, thus completing the limiting and fixing of the battery cover body. Then, the working end of the torque wrench (equipped with a directional locking block) is inserted into the square groove. One hand holds the torque wrench while the other hand rotates the battery cover body, allowing the torque wrench to detect the assembly torque of the terminal body. During this process, the upper conical protrusion engages with the lower conical protrusion to lock the terminal body, preventing circumferential slippage during testing.
[0016] 2. When machining the test fixture, the multi-axis robotic arm is positioned near the lubrication mechanism. The lubrication mechanism applies tapping oil to the working end surface of the tap. The operator places the drilled U-shaped block on the clamping mechanism, which limits and fixes the U-shaped block. Then, the multi-axis robotic arm moves with the working motor and the tap closer to the U-shaped block and processes threads in the through hole of the U-shaped block. During this process, because the working end surface of the tap is coated with tapping oil, the friction between the tap and the U-shaped block is reduced, the cutting force is lowered, and the tap is prevented from jamming or breaking.
[0017] 3. During use, the multi-axis robotic arm is positioned close to the solution cylinder. The working end of the tap is inserted into the tapping oil inside the solution cylinder. After the U-shaped block is clamped and fixed on the clamping mechanism, the multi-axis robotic arm drives the working motor and the tap to move upward, thereby moving the tap upward away from the solution cylinder. During this process, the brush ring will scrape off the excess tapping oil on the surface of the tap, preventing the tapping oil on the tap from dripping onto the upper surface of the worktable and wasting resources while the multi-axis robotic arm drives the working motor and the tap to move.

[0020] 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.
[0021] Reference Figures 1-19A torque testing fixture for battery cover terminals includes a torque wrench and a U-shaped block 100. One side of the U-shaped block 100 has an upper mounting notch 101 and a lower mounting notch 102. An upper T-shaped pressure block 103 is movably mounted within the upper mounting notch 101. Multiple upper conical protrusions 104 are fixed to the lower surface of the upper T-shaped pressure block 103. Two upper pins 105 are fixedly disposed through the upper end face of the U-shaped block 100. The end face has a threaded hole 106 that extends through to the upper mounting notch 101. A locking screw 107 is threaded into the threaded hole 106. A lower T-shaped pressure block 108 is provided in the lower mounting notch 102. Multiple lower conical protrusions 109 are fixed on the upper surface of the lower T-shaped pressure block 108. Two lower pins 110 are fixedly provided through the lower end face of the U-shaped block 100. A square groove 111 for use with a torque wrench is provided on the lower end face of the U-shaped block 100.
[0022] Torque wrenches are existing technology.
[0023] By setting two upper pins 105, the upper T-shaped pressure block 103 is limited so that it can only move up and down and cannot move horizontally, thus preventing the upper T-shaped pressure block 103 from falling out of the upper mounting notch 101.
[0024] The lower T-shaped pressure block 108 is limited by the two lower pins 110. Since the size of the lower mounting notch 102 and the lower T-shaped pressure block 108 are matched, the lower T-shaped pressure block 108 is first limited and fixed. The lower T-shaped pressure block 108 cannot move up and down or translate in the left and right directions.
[0025] In the initial state, the locking screw 107 does not engage with or lock the upper T-shaped pressure block 103, so the upper T-shaped pressure block 103 can move up and down, making it convenient for the staff to insert the end of the battery cover body 700 with the terminal body 701 into the U-shaped block 100.
[0026] During use, the operator can manually push the upper T-shaped pressure block 103 upwards, then insert the end of the battery cover body 700 with the terminal body 701 into the U-shaped block 100. Then, release the upper T-shaped pressure block 103. At this point, the upper conical protrusion 104 at the lower end of the upper T-shaped pressure block 103 presses against the upper surface of the terminal body 701. Simultaneously, the lower surface of the terminal body 701 contacts the multiple lower conical protrusions 109 on the lower T-shaped pressure block 108. Then, rotate and tighten the locking screw 107. During this process, the locking screw 107 will move downwards relative to the U-shaped block 100 until the lower end of the locking screw 107 abuts against... The upper T-shaped pressure block 103 moves downward together, so that the upper conical protrusion 104 and the lower conical protrusion 109 engage and lock the terminal body 701, thus completing the limiting and fixing of the battery cover body 700. Then, the working end of the torque wrench (with a directional locking block) is inserted into the square groove 111. Then, one hand holds the torque wrench and the other hand rotates the battery cover body 700, so that the torque wrench can detect the assembly torque of the terminal body 701. During this process, the upper conical protrusion 104 and the lower conical protrusion 109 engage and lock the terminal body 701, and there will be no circumferential slippage during the test.
[0027] The tightening of the locking screw 107 can also be achieved using tools such as wrenches, which is an existing technology.
[0028] A processing device for a battery cover terminal torque testing fixture, used to produce the aforementioned battery cover terminal torque testing fixture, includes a worktable 200. A multi-axis robotic arm 201 is movably mounted on the upper surface of the worktable 200. A working motor 202 is fixed to one end of the multi-axis robotic arm 201. A tap 203 is detachably mounted on the end of the drive shaft of the working motor 202. The installation and removal of the tap 203 is prior art. A clamping mechanism is provided on the upper surface of the worktable 200. A lubrication mechanism for use with the tap 203 is provided on the upper surface of the worktable 200. A translation mechanism for use with the multi-axis robotic arm 201 is provided on the worktable 200.
[0029] The multi-axis robotic arm 201 is existing technology. It can drive the working motor 202 to lift and translate, and cooperate to perform tapping operations. It is a conventional technical means in this field.
[0030] When manufacturing the U-shaped block 100, a through hole matching the size of the threaded hole 106 needs to be drilled on the upper end face of the U-shaped block 100 first, and then threads are machined on the inner wall of the through hole using a tapping machine or other equipment.
[0031] In use, the multi-axis robotic arm 201 is positioned near the lubrication mechanism. The lubrication mechanism coats the working end of the tap 203 with tapping oil. The operator places the drilled U-shaped block 100 onto the clamping mechanism, which then limits and fixes the U-shaped block 100. The multi-axis robotic arm 201, along with the working motor 202 and the tap 203, moves closer to the U-shaped block 100 and processes threads in the through hole of the U-shaped block 100. During this process, because the working end of the tap 203 is coated with tapping oil, the friction between the tap 203 and the U-shaped block 100 is reduced, the cutting force is lowered, and the tap 203 is prevented from jamming or breaking.
[0032] The lubrication mechanism includes a pad 204 fixed to the workbench 200, a solution cylinder 205 fixed to the upper end of the pad 204, the upper end of the solution cylinder 205 being open, the solution cylinder 205 containing tapping oil, an upper mounting ring 206 provided at the upper end of the solution cylinder 205, and a brush ring 207 fixed on the inner wall of the upper mounting ring 206.
[0033] During use, the multi-axis robotic arm 201 is positioned close to the solution cylinder 205. The working end of the tap 203 is inserted into the tapping oil inside the solution cylinder 205. After the U-shaped block 100 is clamped and fixed on the clamping mechanism, the multi-axis robotic arm 201 drives the working motor 202 and the tap 203 to move upward, thereby moving the tap 203 upward away from the solution cylinder 205. During this process, the brush ring 207 scrapes off the excess tapping oil on the surface of the tap 203, preventing the tapping oil on the tap 203 from dripping onto the upper surface of the worktable 200 during the movement of the multi-axis robotic arm 201 and the working motor 202, thus avoiding resource waste.
[0034] A lower mounting ring 208 is provided below the upper mounting ring 206. Multiple connecting plates 209 are fixed between the upper mounting ring 206 and the lower mounting ring 208. Multiple lower engaging balls 210 are fixed on the outer surface of the solution cylinder 205 near the lower section. Multiple engaging grooves for use with the lower engaging balls 210 are provided on the inner wall of the lower mounting ring 208. Multiple guide slots 211 for use with the connecting plates 209 are provided on the outer surface of the solution cylinder 205.
[0035] In use, the lower mounting ring 208 engages with the surface of the lower engaging ball 210, thereby limiting and fixing the lower mounting ring 208, which in turn limits and fixes the connecting plate 209 and the upper mounting ring 206, allowing the brush ring 207 to perform oil scraping operation on the tap 203.
[0036] A drain pipe 300 is connected to one side of the solution cylinder 205. A valve 301 is installed on the drain pipe 300. An internal ring 302 is installed inside the solution cylinder 205. A filter layer 303 is fixed on the inner wall of the internal ring 302. Multiple connecting posts 304 are fixed between the upper end face of the internal ring 302 and the upper mounting ring 206. Multiple upper locking balls 305 are fixed on the outer surface of the solution cylinder 205 near the upper section.
[0037] In the initial state, the built-in ring 302 and the filter layer 303 are located at the inner bottom of the solution cylinder 205.
[0038] After the processing equipment of this application has finished processing a batch of U-shaped blocks 100, the multi-axis robotic arm 201 can be moved away from the solution cylinder 205 with the working motor 202 and the tap 203, and then the tap 203 can be removed and maintained. This part is prior art.
[0039] Then, pull the lower mounting ring 208 upwards, causing the connecting plate 209 and the upper mounting ring 206 to move upwards together. The upper mounting ring 206 then moves the connecting column 304, the inner ring 302, and the filter layer 303 upwards together until the lower mounting ring 208 engages with the upper engaging ball 305. The upper engaging ball 305 limits and fixes the lower mounting ring 208. Then, the external container can be placed at the lower end of the drain pipe 300, and the valve 301 can be opened to discharge and collect the remaining tapping oil in the solution container 205 for the next use. During this process, the filter layer 303 adsorbs and collects the iron filings in the tapping oil. At this time, because the lower mounting ring 208 is... The upper locking ball 305 is engaged, so there is a certain distance between the inner ring 302 and the filter layer 303 and the bottom of the solution cylinder 205. Therefore, it will not affect the drainage of the drain pipe 300. When the tapping oil in the solution cylinder 205 is basically drained, there will not be too much tapping oil adhering to the inner ring 302 and the filter layer 303 (excess tapping oil drips to the bottom of the solution cylinder 205). When the upper mounting ring 206, connecting plate 209, lower mounting ring 208, connecting column 304, inner ring 302 and filter layer 303 are removed from the solution cylinder 205 together, there is no excess tapping oil dripping from the inner ring 302 and the filter layer 303 onto the upper surface of the workbench 200.
[0040] The clamping mechanism includes a placement seat 400 fixed to the upper surface of the worktable 200. A positioning block 401 and a fixed seat 402 are fixed to the upper surface of the placement seat 400. An abutment block 403 is movably arranged between the positioning block 401 and the fixed seat 402. A lead screw 404 is rotatably arranged on one side of the abutment block 403. One end of the lead screw 404 is threaded through the fixed seat 402 and a handwheel 405 is fixed thereon. Two guide posts 406 are fixed to one side of the abutment block 403. Each guide post 406 movably passes through the fixed seat 402. A U-shaped protective cover 407 is fixed on the side wall of the abutment block 403.
[0041] When in use, the U-shaped block 100 to be processed can be placed between the positioning block 401 and the abutment block 403, and then the handwheel 405 can be turned to drive the abutment block 403 to move closer to the U-shaped block 100, so as to clamp and fix the U-shaped block 100 in conjunction with the positioning block 401.
[0042] The upper surface of the positioning block 401 may be provided with scale lines, etc., for use in coordinating the placement and positioning of the workpiece. This part is a conventional technical means in this field.
[0043] A movable seat 500 is movably mounted on the upper surface of the workbench 200. A recessed groove is formed on the upper surface of the movable seat 500. An electric push rod 501 is fixed in the recessed groove. A lifting plate 502 is fixed to the end of the telescopic end of the electric push rod 501. An air blowing hood 503 is fixed on the upper surface of the lifting plate 502. An air pump 504 is provided on one side of the workbench 200. A telescopic hose 505 is provided between the air outlet of the air pump 504 and the air blowing hood 503. A translation mechanism 1 that works with the movable seat 500 is provided on the workbench 200. A waste collection assembly is provided on the workbench 200. A U-shaped baffle 506 is fixed on the upper surface of the workbench 200. Two guide posts 507 are symmetrically fixed on the lower surface of the lifting plate 502. Each guide post 507 movably extends into the movable seat 500.
[0044] In the initial state, the movable seat 500, electric push rod 501, lifting plate 502, and air blowing hood 503 are positioned close to the solution cylinder 205. Each time the operator removes the processed U-shaped block 100 from the clamping mechanism, the movable seat 500 drives the electric push rod 501, lifting plate 502, and air blowing hood 503 to move horizontally. During this process, the air pump 504 blows the debris located on the clamping mechanism into the waste collection assembly, eliminating the need for manual cleaning.
[0045] The electric actuator 501 can be used to push the lifting plate 502 and the air blowing cover 503 to move up and down, in order to help clean the processing debris on the placement seat 400, the positioning block 401, and the U-shaped protective cover 407.
[0046] After the tap 203 finishes machining the U-shaped block 100, machining debris will adhere to the surface of the tap 203. When the multi-axis robotic arm 201 drives the tap 203 into the solution cylinder 205, the tap 203 will pass through the brush ring 207. The brush ring 207 can scrape off most of the machining debris adhering to the surface of the tap 203. At this time, the still-unmoving moving seat 500, electric push rod 501, lifting plate 502 and air blowing hood 503 can blow air on the upper surface of the tap 203 and the brush ring 207 to clean the debris.
[0047] The waste collection assembly includes a discharge trough 508 on the upper surface of the workbench 200, a side passage 509 extending through the discharge trough 508 on one side of the workbench 200, a collection frame 510 placed in the side passage 509, and a guide plate 511 fixed at an inclination in the discharge trough 508.
[0048] The airflow from the air blower 503 blows the processing debris located on the placement seat 400, positioning block 401, and U-shaped protective cover 407 into the discharge chute 508, and then guides the processing debris into the collection frame 510 through the guide plate 511.
[0049] The translation mechanism includes a sliding groove 600 formed on the upper surface of the worktable 200, a sliding block 601 slidably disposed in the sliding groove 600, and a drive unit 500 used in conjunction with the sliding block 601 disposed in the sliding groove 600. The moving seat 500 is fixed to the upper surface of the sliding block 601. The drive unit 500 is prior art, and the displacement of the sliding block 601 is a conventional technical means in the field.
[0050] The drive unit 1 causes the sliding block 601 to move horizontally within the sliding groove 600, thereby driving the moving seat 500, electric push rod 501, lifting plate 502 and air blowing cover 503 to move.
[0051] The translation mechanism 2 includes a sliding groove 2 602 formed on the upper surface of the worktable 200, a sliding block 2 603 slidably disposed in the sliding groove 2 602, and a drive unit 2 used in conjunction with the sliding block 2 603 disposed in the sliding groove 2 602. The multi-axis robotic arm 201 is fixed to the upper surface of the sliding block 2 603. The drive unit 2 is prior art, and the displacement of the sliding block 2 603 is a conventional technical means in this field.
[0052] The second driving unit causes the second sliding block 603 to move within the second sliding groove 602, thereby driving the multi-axis robotic arm 201 to move.
[0053] In use, the operator can manually push the upper T-shaped pressure block 103 upwards, then insert one end of the battery cover body 700 with the terminal body 701 into the U-shaped block 100. After releasing the upper T-shaped pressure block 103, the upper conical protrusion 104 at the lower end of the upper T-shaped pressure block 103 presses against the upper surface of the terminal body 701. At this time, the lower surface of the terminal body 701 contacts the multiple lower conical protrusions 109 on the lower T-shaped pressure block 108. Then, the locking screw 107 is rotated and tightened. During this process, the locking screw 107 moves downwards relative to the U-shaped block 100 until the lower end of the locking screw 107 abuts against... The upper T-shaped pressure block 103 moves downward together, so that the upper conical protrusion 104 and the lower conical protrusion 109 engage and lock the terminal body 701, thus completing the limiting and fixing of the battery cover body 700. Then, the working end of the torque wrench (equipped with a directional locking block) is inserted into the square groove 111. Then, one hand holds the torque wrench and the other hand rotates the battery cover body 700, so that the torque wrench can detect the assembly torque of the terminal body 701. During this process, the upper conical protrusion 104 and the lower conical protrusion 109 engage and lock the terminal body 701, and there will be no circumferential slippage problem during the test. When processing the aforementioned battery cover terminal torque testing fixture, the multi-axis robotic arm 201 is positioned near the lubrication mechanism. The lubrication mechanism applies tapping oil to the working end surface of the tap 203. The operator places the drilled U-shaped block 100 onto the clamping mechanism, which limits and fixes the U-shaped block 100. Then, the multi-axis robotic arm 201, along with the working motor 202 and the tap 203, moves closer to the U-shaped block 100 and processes threads in the through hole of the U-shaped block 100. During this process, because the working end surface of the tap 203 is coated with tapping oil, the friction between the tap 203 and the U-shaped block 100 can be reduced during tapping, thus reducing the cutting force and preventing the tap 203 from jamming or breaking. During use, the multi-axis robotic arm 201 is positioned close to the solution cylinder 205. The working end of the tap 203 is inserted into the tapping oil inside the solution cylinder 205. After the U-shaped block 100 is clamped and fixed on the clamping mechanism, the multi-axis robotic arm 201 drives the working motor 202 and the tap 203 to move upward, thereby moving the tap 203 upward away from the solution cylinder 205. During this process, the brush ring 207 scrapes off the excess tapping oil on the surface of the tap 203, preventing the tapping oil on the tap 203 from dripping onto the upper surface of the worktable 200 during the movement of the multi-axis robotic arm 201 and the working motor 202, thus avoiding resource waste.
