Description

Technical Field

[0001] This utility model patent relates to the field of current collector processing technology, and in particular to a positioning tool for processing the side groove of a current collector. Background Technology

[0002] The current collector is a core component in a battery system, responsible for current collection and conduction. Its conductivity and structural stability directly affect the battery's charge-discharge efficiency and operational reliability. In the Kirin battery structure, the current collector and the water-cooling plate form a synergistic unit, employing a configuration of one water-cooling plate for two current collectors, with the current collectors located on opposite sides of the water-cooling plate. This dual-sided layout design not only increases the current collection area to improve conductivity but also optimizes the heat conduction path through close cooperation with the water-cooling plate, which is of great significance for enhancing the overall performance of the battery.

[0003] In the machining process of manifolds, one step requires machining the side grooves of the manifold. Currently, the existing positioning machining method uses multiple spacers and bolts to position and install the manifold. After machining, it needs to be disassembled and repositioned for the next manifold, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] To improve processing efficiency, this utility model patent provides a positioning fixture for processing the side groove of a fluid collector.

[0005] This utility model patent provides a positioning fixture for machining the side groove of a fluid collector, which adopts the following technical solution:

[0006] A positioning fixture for machining a side groove of a collector includes a mounting plate. The mounting plate is provided with at least one set of positioning components. The positioning components include two fixing parts and a positioning part. The positioning part is located between the two fixing parts. The collector is located between the fixing parts and the positioning part. The mounting plate is provided with a driving part for driving the positioning part to move. The driving part drives the positioning part to move, and the positioning part clamps the collector onto the fixing parts.

[0007] By adopting the above technical solution, when processing the current collector, at least two current collectors are first placed on corresponding fixed parts, and the positioning parts are moved by the driving parts. One positioning part clamps and fixes the two current collectors at the same time. In this way, at least two current collectors can be processed in one clamping, thus improving processing efficiency.

[0008] Optionally, the fixing member includes a fixing seat, the fixing seat is provided with two blocks, the fixing seat is provided with a relief groove between the two blocks, the fixing seat is provided with at least two top blocks, the top blocks are used to support the two shoulders of the collector, and the side of the top block contacts the side wall of the collector.

[0009] By adopting the above technical solution, when installing the collector, the shoulder of the collector is first placed on the top block, and its larger side abuts against the stop block. The side of the top block contacts the side of the collector, and the clearance groove can accommodate the ring of the collector. This allows the collector to be installed on the fixed base conveniently and quickly.

[0010] Optionally, in order to match the profile of the current collector, one of the top blocks is provided with a positioning notch for contact with the current collector profile.

[0011] By adopting the above technical solution, the positioning notch provides further support for the manifold, which helps to improve the support effect and increase the installation stability of the manifold.

[0012] Optionally, the mounting base is provided with an installation notch for placing the top block.

[0013] By adopting the above technical solution, the top block is supported by the installation notch, which helps to increase the installation stability of the top block.

[0014] Optionally, since the current collectors come in different models with varying lengths and widths, several connecting holes are provided on the sidewall of the mounting notch to match current collectors of different shapes, and a waist-shaped hole for bolts to pass through is provided on the sidewall of the top block. The top block connects to different connecting holes, allowing its position to be adjusted to accommodate current collectors of different lengths, thereby increasing the types of parts that can be processed.

[0015] By adopting the above technical solution, the top block is installed on the fixed base with bolts, so that top blocks of different shapes can be installed to adapt to different models of manifolds.

[0016] Optionally, the side wall of the top block is provided with a recessed groove that communicates with the waist-shaped hole.

[0017] By adopting the above technical solution, the head of the bolt can be sunk into the slotted hole using the countersink, thus avoiding affecting the clamping block's clamping of the collector.

[0018] Optionally, the positioning element includes a pushing block disposed on the mounting plate, the pushing block having a sliding groove, a dovetail block slidingly disposed in the sliding groove, the trajectory of the dovetail block sliding in the dovetail groove being parallel to the axis of the tool for machining the side groove, a pushing plate connected to the pushing block, and two abutting blocks disposed on the pushing plate, the abutting blocks being correspondingly disposed with the stop blocks;

[0019] The driving component includes a cylinder mounted on a mounting plate, the cylinder being connected to a dovetail block, and the axis of the cylinder being parallel to the axis of the tool used for machining the side groove.

[0020] By adopting the above technical solution, the dovetail block is moved by the cylinder, and the dovetail block moves down along the dovetail groove. The dovetail block drives the push plate and the pressing block to move towards the fixed seat, so that the collector can be pressed against the top block and the fixed seat.

[0021] In summary, this utility model patent includes at least one of the following beneficial technical effects: By using a driving component to move the positioning component, at least two current collectors can be clamped onto the fixing component simultaneously, allowing for the processing of multiple workpieces in a single clamping operation. This avoids the cumbersome operation of repeated disassembly and installation in traditional positioning methods using multiple pads and bolts, significantly saving labor time. Simultaneously, the fixing component, through structures such as stops, top blocks, and positioning notches, can accurately match the contour of the current collector, ensuring its stability during processing in conjunction with the clamping action of the positioning component. The top block, with the cooperation of the oblong hole and the connecting hole, can adapt to the positioning requirements of different types of current collectors, enhancing the versatility of the tooling. In conclusion, this tooling significantly improves the processing efficiency of the side groove of the current collector while ensuring processing accuracy. Attached Figure Description

The collector 5 is located between the fixing parts 3 and the positioning part 4. The mounting plate 1 is provided with a driving part 6 for driving the positioning part 4 to move. The driving part 6 drives the positioning part 4 to move, and the positioning part 4 clamps the collector 5 onto the fixing parts 3.

[0028] The positioning component 4 includes a pad 7 set on the mounting plate 1. The pad 7 is provided with a pushing block 8. The pad 7 is used to raise the height of the pushing block 8 so that its height matches the height of the collector 5. The pushing block 8 is provided with a sliding groove 9. The sliding groove 9 is a dovetail groove. The width of the sliding groove 9 increases from the side closer to the mounting plate 1 to the side farther away from the mounting plate 1. A dovetail block 10 is slidably provided in the sliding groove 9. The trajectory of the dovetail block 10 sliding in the dovetail groove is parallel to the axis of the tool for machining the side groove. A pushing plate 11 is connected to the pushing block 8. The pushing plate 11 is provided with two abutting blocks 12. A space is left between the two abutting blocks 12 for the ring of the collector 5 to be placed.

[0029] The drive unit 6 includes a cylinder 13 mounted on the bottom wall of the mounting plate 1. The piston rod of the cylinder 13 passes through the mounting plate 1 and is connected to the dovetail block 10. The axis of the cylinder 13 is parallel to the axis of the tool for machining the side groove.

[0030] The fixing member 3 includes a fixing base 14, on which two stops 15 are provided. The stops 15 are correspondingly arranged with the abutting block 12. A relief groove 16 is provided on the fixing base 14 and between the two stops 15. In this embodiment, the relief groove 16 is an arc-shaped groove. The relief groove 16 is used for placing the annular current collector 5. The fixing base 14 is provided with at least two top blocks 17. The top blocks 17 are used to support the two shoulders of the current collector 5. The side of the top block 17 contacts the side wall of the current collector 5.
