Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a quick-clamping fixture for battery cover manufacturing with a quick-locking buckle. Background Technology

[0002] Battery covers are protective and sealing components of battery packs, typically made of materials such as plastic or metal. They are used to cover the battery body, prevent foreign objects from entering, and ensure safe use. Battery cover production quick-clamping fixtures are specialized tooling used in battery cover processing (such as injection molding, stamping, and grinding). Their core function is to quickly position and clamp the battery cover to be processed. By simplifying operations and shortening clamping time, they adapt to the needs of mass production, while ensuring the stability and accuracy of the workpiece during processing, thus helping to improve production efficiency and product consistency.

[0003] When spraying antistatic coatings on the inner wall of a battery cover, the battery cover needs to be clamped stably without affecting the uniformity and integrity of the coating. However, existing fixtures, such as those using motor extrusion, are prone to causing excessive local stress on the battery cover, leading to deformation and uneven coating. Therefore, manual locking is used to lock the battery cover to improve production quality and efficiency. However, the commonly used manual locking process is cumbersome, and after locking, the elasticity is poor, which can easily lead to over-locking or under-locking. This can cause gaps between the fixture and the battery cover or cause stress concentration, affecting the coating quality. In addition, after the coating is completed, the battery cover is embedded in the fixture due to the fixing effect, making disassembly difficult.

[0004] Therefore, we provide a quick-clamping fixture for battery cover production with a quick-locking buckle to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a quick-clamping fixture for battery cover production with a quick-locking buckle, aiming to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: It includes a fixed substrate, a battery cover fixing groove welded to the upper side of the fixed substrate, a battery cover production auxiliary component disposed on the inner side of the battery cover fixing groove, the battery cover production auxiliary component including a vacuum generator installed on the lower side of the fixed substrate, vacuum suction ports disposed in the middle of the inner side of the battery cover fixing groove, a battery cover body fitted into the inner side of the battery cover fixing groove, a battery cover quick-locking structure disposed on the outer side of the battery cover fixing groove, the battery cover quick-locking structure including a battery cover pressure frame installed on the outer side of the battery cover fixing groove, a pressure frame buckle plate welded to the right side of the battery cover pressure frame, a locking pad welded to the right side of the fixed substrate, a locking bracket welded to the right side of the locking pad, a pressure buckle installed on the inner side of the locking bracket, and a locking buckle installed on the inner side of the pressure buckle.

[0007] Preferably, the outer pipe of the vacuum generator is connected to a vacuum tank, and a foot pedal control button is electrically connected to one side of the vacuum generator. The vacuum inlet and the vacuum tank form a vacuum adsorption structure through the vacuum generator. A negative pressure pad is provided on the outer surface of the vacuum inlet, and the negative pressure pad works with the vacuum inlet to assist in adsorption.

[0008] Preferably, hydraulic pump bodies are provided on both the left and right sides of the vacuum suction port, and hydraulic columns are installed on the inner side of the hydraulic pump bodies. The hydraulic pump bodies are arranged symmetrically in two groups on the left and right sides, and the hydraulic pump bodies and the battery cover body form a hydraulic lifting structure through the hydraulic columns.

[0009] Preferably, the battery cover pressure frame and the left side of the battery cover fixing groove are axially connected, the outer diameter of the battery cover pressure frame and the battery cover fixing groove are the same, and the four corner pressure pads of the battery cover pressure frame are bonded to the four corners of the inner corners of the pressure frame, and the four corner pressure pads of the pressure frame are made of elastic rubber.

[0010] Preferably, the buckle and the locking bracket are connected by a shaft, and the lock and the buckle are connected by a shaft. A locking head is installed at the top of the lock. The buckle drives the lock to rotate downward, so that the locking head engages with the buckle plate.

[0011] Preferably, a release counterweight is welded to the outer side of the locking head. The release counterweight drives the locking buckle to rotate outward along the locking frame and release the pressure frame buckle plate through the locking head.

[0013] This invention provides a quick-clamping fixture for manufacturing battery caps with a quick-locking buckle. Compared with the prior art, it has the following advantages:

[0014] 1. This is a quick-clamping fixture for battery cover production with a quick-locking buckle. When needed, the operator places the battery cover into the battery cover fixing slot, presses the foot pedal control button, and the vacuum generator starts. The vacuum tank, together with the vacuum suction port, extracts the air between the battery cover and the negative pressure pad to create negative pressure, achieving stable adsorption of the battery cover. After the internal coating of the battery cover is sprayed, the operator releases the foot pedal control button, the vacuum generator cancels the vacuum adsorption, and the two sets of hydraulic pumps on the left and right start simultaneously. The hydraulic columns extend synchronously, pushing the battery cover to rise smoothly and detach from the battery cover fixing slot, making it easy for the operator to quickly remove the processed battery cover.

[0015] 2. This quick-clamping fixture for battery cover manufacturing with a quick-locking buckle is used when the operator flips the battery cover frame above the battery cover fixing slot. The operator then lifts the buckle upwards, aligning the locking head with the upper edge of the frame buckle plate. The buckle is then pressed down, causing the locking head to engage with the frame buckle plate, thus firmly fixing the battery cover frame to the battery cover fixing slot. When the locking head is locked in the frame buckle plate, the auxiliary damping is compressed synchronously with the downward pressure of the locking head, producing a slight deformation to reinforce the locking stability of the battery cover frame and prevent the contact surface between the locking head and the frame buckle plate from loosening due to vibration or external force.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This utility model provides a technical solution: a quick clamping fixture for producing battery covers with quick-locking buckles, including a fixed base plate 1, a battery cover fixing groove 2 welded to the upper side of the fixed base plate 1, a battery cover production auxiliary component 3 provided inside the battery cover fixing groove 2, the battery cover production auxiliary component 3 including a vacuum generator 301 installed on the lower side of the fixed base plate 1, a vacuum suction port 304 provided in the middle of the inner side of the battery cover fixing groove 2, a battery cover body 4 fitted inside the battery cover fixing groove 2, a battery cover quick-locking structure 5 provided outside the battery cover fixing groove 2, the battery cover quick-locking structure 5 including a battery cover pressure frame 501 installed outside the battery cover fixing groove 2, a pressure frame buckle plate 503 welded to the right side of the battery cover pressure frame 501, a locking pad plate 504 welded to the right side of the fixed base plate 1, a locking bracket 505 welded to the right side of the locking pad plate 504, a buckle 506 installed inside the locking bracket 505, and a locking buckle 507 installed inside the buckle 506.

[0026] The vacuum generator 301 has an outer pipe connected to a vacuum tank 302. A foot pedal control button 303 is electrically connected to one side of the vacuum generator 301. The vacuum suction port 304 and the vacuum tank 302 form a vacuum adsorption structure through the vacuum generator 301. A negative pressure pad 305 is provided on the outer surface of the vacuum suction port 304. The negative pressure pad 305 works with the vacuum suction port 304 to assist in adsorption.

[0027] When needed, the operator places the battery cover 4 into the battery cover fixing slot 2, presses the foot pedal control button 303, and the vacuum generator 301 starts. The vacuum tank 302, together with the vacuum suction port 304, extracts the air between the battery cover 4 and the negative pressure pad 305 to form a negative pressure, thereby achieving stable adsorption of the battery cover 4.

[0028] Hydraulic pump bodies 306 are provided on both the left and right sides of the vacuum suction port 304. Hydraulic columns 307 are installed on the inner side of the hydraulic pump bodies 306. The hydraulic pump bodies 306 are arranged symmetrically in two groups on the left and right. The hydraulic pump bodies 306 and the battery cover 4 form a hydraulic lifting structure through the hydraulic columns 307.

[0029] After the coating inside the battery cover 4 is sprayed, the operator releases the foot pedal control button 303, the vacuum generator 301 cancels the vacuum adsorption, the two sets of hydraulic pumps 306 start at the same time, the hydraulic column 307 extends synchronously, pushing the battery cover 4 to rise smoothly and get off the battery cover fixing groove 2, so that the operator can quickly remove the processed battery cover 4.

[0030] The battery cover pressure frame 501 is axially connected to the left side of the battery cover fixing groove 2. The outer diameter of the battery cover pressure frame 501 and the battery cover fixing groove 2 are the same. The four corner pressure pads 502 are bonded to the four corners of the battery cover pressure frame 501 and are made of elastic rubber.

[0031] After the battery cover 4 is placed into the battery cover fixing groove 2, the operator flips the battery cover pressing frame 501 downwards so that the outer frame of the battery cover pressing frame 501 is locked onto the outer edge of the battery cover fixing groove 2. The four corner pressing pads 502 of the pressing frame are tightly attached to the four corners of the upper surface of the battery cover 4, thereby applying uniform pressure to the battery cover 4 from the top. The four corner pressing pads 502 of the pressing frame are small in size and the surface is made of elastic rubber material, which can effectively provide clamping force and reduce the obstruction area during the spraying process.

[0032] The buckle 506 and the locking bracket 505 are connected by a shaft, and the lock 507 and the buckle 506 are connected by a shaft. The top of the lock 507 is equipped with a locking head 508. The buckle 506 drives the lock 507 to rotate downward, so that the locking head 508 engages with the buckle plate 503.

[0033] When needed, the operator flips the battery cover frame 501 over the battery cover fixing groove 2, then lifts the latch 507 upwards so that the locking head 508 is aligned with the upper edge of the frame buckle 503. Then, the operator presses down the latch 506, which causes the latch 506 to move the latch 507 downwards, so that the locking head 508 engages and locks the frame buckle 503, thus firmly fixing the battery cover frame 501 to the battery cover fixing groove 2.

[0034] A release counterweight 509 is welded to the outside of the locking head 508. The release counterweight 509 drives the latch 507 to rotate outward along the locking bracket 505 and disengage from the pressure frame buckle 503 through the locking head 508.

[0035] When it is necessary to release the battery cover pressure frame 501, the operator lifts the pressure buckle 506 upwards. At this time, the locking head 508 will disengage from the pressure frame buckle plate 503. The counterweight 509 will then fall rapidly due to its own gravity, causing the locking head 508 and the latch 507 to flip outwards, thereby achieving a rapid release effect.

[0036] An auxiliary damper 510 is installed in the middle of the locking head 508. The auxiliary damper 510 is arranged in two sets, and the end of the auxiliary damper 510 abuts against the pressure frame buckle plate 503.

[0037] When the locking clip 508 is locked onto the pressure frame plate 503, the auxiliary damper 510 will be compressed synchronously as the locking clip 508 is pressed down, producing a slight deformation to strengthen the locking stability of the battery cover pressure frame 501 and prevent the contact surface between the locking clip 508 and the pressure frame plate 503 from loosening due to vibration or external force.

[0038] Working principle: When needed, the fixing base plate 1 is fixed on the processing table, and then the battery cover 4 is embedded in the battery cover fixing groove 2. At this time, the operator rotates the battery cover pressing frame 501 so that the battery cover pressing frame 501 covers the outer edge of the battery cover fixing groove 2, and the pressing frame corner pads 502 at the four corners of the battery cover pressing frame 501 press against the four corners of the battery cover 4. Through the flexible rubber material of the pressing frame corner pads 502, the pressing force on the four corners of the battery cover 4 is elastically supplemented.

[0039] Once ready, the operator attaches the locking head 508 at the top of the latch 507 to the pressure frame plate 503. By pressing down the buckle 506, the latch 507 pulls the locking head 508 downward, allowing the locking head 508 to engage with the pressure frame plate 503. On this basis, the auxiliary damper 510 will be compressed synchronously due to the downward pressure of the locking head 508, thereby further enhancing the stability of the locking structure through elastic deformation.

[0040] After it is fixed, the operator steps on the foot pedal control button 303 to start the vacuum generator 301. Air is drawn into the vacuum tank 302 through the vacuum suction port 304. With the help of the negative pressure pad 305, the contact surface between the battery cover fixing groove 2 and the battery cover body 4 forms a negative pressure adsorption, which further fixes the bottom of the battery cover body 4.

[0041] Finally, after the coating spraying operation is completed, the operator releases the foot pedal control button 303, the vacuum generator 301 stops working, and then the operator lifts the pressing buckle 506 upward, driving the locking buckle 507 upward, so that the locking head 508 disengages from the pressure frame buckle plate 503. At this time, due to the influence of the disengaged counterweight 509, the top is heavy and the bottom is light, causing the locking head 508 to tilt outward, achieving the effect of complete release. Finally, the operator lifts the battery cover pressure frame 501, controls the hydraulic pump body 306 to start, drives the hydraulic column 307 upward, and smoothly pushes the battery cover 4 out of the battery cover fixing groove 2, making it easy for the operator to take out. This completes the use of a quick clamping fixture for battery cover production with a quick locking buckle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
