Description

Technical Field

[0001] This utility model belongs to the field of current collector processing technology, specifically, it relates to a processing fixture for current collectors. Background Technology

[0002] Current collectors are components used in batteries and other fields to collect and conduct current, playing a crucial role in the normal operation and performance of the equipment. In Kirin batteries, current collectors are closely integrated with water-cooling plates, with 36 water-cooling plates paired with 72 current collectors per group. Current collectors are located on both sides of the water-cooling plate. Currently, the common method for processing current collectors is to clamp the blank material with bolts and clamps, then use bolts to mount the clamps on a machine tool, and finally mill the blank material. When processing a large number of blanks, this clamping process is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to provide a processing fixture for current collectors, which uses a rotating cylinder piston rod to drive a clamping head to fix the carrier plate, replacing the bolt fixing method. On the one hand, this increases the convenience of installation and improves efficiency; on the other hand, the carrier plate can be replaced according to the shape of the workpiece, thereby increasing the range of applicable processing methods.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] A machining fixture for current collectors includes a base and a carrier plate. A rotary cylinder is provided on the base, and a clamping head is provided on the piston rod of the rotary cylinder. A slot is provided on the carrier plate, and a through hole is provided on the bottom wall of the slot for the clamping head to pass through. The clamping head passes through the through hole and clamps the bottom wall of the slot.

[0006] During processing, the base is first installed on the machine tool, the blank is installed on the carrier plate, the carrier plate is placed on the base, the clamping head is fitted into the through hole, and the rotating cylinder drives the clamping head to rotate and press down. The clamping head presses against the bottom wall of the slot, thereby fixing the carrier plate on the base. This allows for convenient and quick fixing of the carrier plate, improving installation efficiency. Moreover, different carrier plates can be installed according to the shape of the blank, which helps to increase the applicability of the processed parts.

[0007] In one specific implementation, the carrier plate has an installation notch on one side, the installation notch communicates with the slot, the installation notch has a locking plate, the locking plate fits into the installation notch, and the locking plate and the carrier plate are connected by bolts.

[0008] When installing the blank, first insert the blank into the slot, then fit the locking plate against the installation notch, and use bolts to lock the locking plate in place. This can enhance the stability of the blank installation.

[0009] In one specific implementation, the height of the locking plate is lower than the maximum height of the carrier plate, and the distance between the two is 3~5mm.

[0010] By positioning the highest point of the locking plate below the maximum height of the carrier plate, machining clearance space can be provided, facilitating machining and avoiding interference with the installation of the blank; in addition, it also helps with chip removal.

[0011] In one specific implementation, the card slots are provided with clearance arc-shaped notches on the opposite slot walls.

[0012] Since the clamping head needs to rotate in the slot, a clearance arc notch is provided on the side wall of the slot to avoid interference and ensure smooth rotation of the clamping head.

[0013] In one specific implementation, a clearance notch is provided at the corner of the card slot.

[0014] When the blank is installed in the slot, the clearance notch is used to avoid the right angle of the blank, thus preventing the accumulation of profit and damage to the blank. Moreover, it is more convenient and faster for the operator to load the blank into the slot, and the blank can be placed in the correct position more smoothly, reducing clamping time and improving processing efficiency.

[0015] In one specific implementation, the locking plate has several protrusions on the side near the slot.

[0016] The protrusions increase the friction between the locking plate and the workpiece, making the workpiece less prone to displacement during machining and thus improving machining accuracy. The protrusions can also compensate for any gaps that may exist between the workpiece and the locking plate, providing good fixation for workpieces of different sizes or with slightly different surfaces, thus improving the versatility and adaptability of the fixture.

[0017] In one specific implementation, on the side away from the locking plate, the top wall of the carrier plate is provided with a machining clearance notch, the height of which is specified.

[0018] When machining the current collector blank, the cutting tool needs to perform cutting operations on the blank. Machining a clearance notch provides sufficient space for the cutting tool, preventing it from colliding or interfering with the carrier plate during machining, ensuring smooth machining, avoiding damage to the cutting tool and carrier plate, and also ensuring machining accuracy. It also facilitates chip removal, keeps the machining area clean, reduces the impact of chips on machining accuracy, and makes cleaning easier.

[0019] In one specific implementation, the clamping head has a through hole for a bolt to pass through, the bottom wall of the clamping head has a positioning notch, and the head of the rotary cylinder piston rod has a boss for inserting into the positioning notch.

[0020] During installation, first insert the boss into the positioning notch, then pass the bolt through the through hole and thread it onto the piston rod. This allows the clamping head to be installed on the piston rod. The boss abuts against the positioning notch, which prevents slippage when tightening the bolt.

[0021] This invention utilizes a rotating cylinder piston rod to drive a clamping head to fix the carrier plate, replacing the traditional bolt fixing method. This allows for quick and easy fixation of the carrier plate on the base, simplifying operation, effectively saving clamping time, and significantly improving installation efficiency. Furthermore, the carrier plate can be replaced according to the shape of the workpiece, adapting to different sizes and shapes of current collector workpieces to meet diverse processing requirements, thus enhancing the versatility and adaptability of the fixture in the field of current collector processing.
