Description

Technical Field

[0001] The utility model relates to the technical field of grinding tools, in particular to a simple grinding tool. Background Art

[0002] During the assembly of steering motors for new energy vehicles, the chamfering of the straight copper busbar heads is a critical step in ensuring assembly accuracy and consistency. As a crucial component of electrical connections, the quality of the straight copper busbar machining directly impacts the performance and reliability of the motor.

[0003] Traditionally, during the mass production stage, manufacturers usually use a stamping process to directly perform chamfering in the mold. Although this method is suitable for large-scale production, it is often not economical during the R&D stage due to the small number of samples, high stamping costs and long production cycles. In addition, the stamping process has high requirements for mold design and manufacturing, which increases initial investment and production risks. In the sample proofing process, manual proofing has become a common choice. However, the accuracy and consistency of manual proofing are difficult to meet the requirements of modern production, especially when there are strict requirements on chamfer angles and dimensions. Manual operation will lead to errors, affecting the quality of subsequent assembly, and even causing the motor performance to substandard, thereby affecting the safety and reliability of the entire vehicle. Therefore, in response to the above shortcomings, a simple grinding tool is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a simple grinding tool, which aims to improve the problems of low processing efficiency of copper bars by some grinding tools in the prior art and inability to adapt to copper bars of different specifications.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] As a further description of the above technical solution:

[0008] The elastic component includes a plurality of sliding sleeves, the tops of the plurality of sliding sleeves are fixedly connected to the bottom of the extrusion plate, the exteriors of the plurality of sliding sleeves are slidably connected to sleeves, the exteriors of the plurality of sliding sleeves are fixedly connected to limit rings, and the interiors of the plurality of sliding sleeves are provided with springs;

[0009] As a further description of the above technical solution:

[0010] The outer portion of the copper busbar is slidably connected to the inner portion of the fixing groove, and the outer portion of the copper busbar is in contact with the top of the extruded plate;

[0011] As a further description of the above technical solution:

[0012] The bottom of the sleeve is fixedly connected to the interior of the positioning block, and the outer portion of the limiting ring is slidably connected to the interior of the sleeve;

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inner top side of the sliding sleeve, and the other end of the spring is fixedly connected to the inner bottom side of the sleeve;

[0015] As a further description of the above technical solution:

[0016] A hand-cranked grinder is arranged outside the grinding block, and the fixing fixture and the positioning block can be adsorbed on the platform of the hand-cranked grinder.

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, by designing multiple consistent tooling grooves, the copper busbar can be tightly clamped to ensure the stability of the relative position of the copper busbar and the tooling. The accuracy of the chamfer is ensured by the inclination angle of the tooling. At the same time, multiple copper busbars can be processed by a manual grinder at the same time, which significantly improves production efficiency and reduces production cycle.

[0019] 2. In the present invention, the tooling can adapt to the processing requirements of various copper bars by adjusting the length of the copper bar extending from the tail end of the slot. Compared with the stamping process, the cost of using this tooling for sample proofing is lower, which is suitable for small-batch production in the research and development stage. It only requires two wire cuttings from different directions with one steel block to form it, reducing manufacturing complexity and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figures 1 to 3 The present invention provides an embodiment of a simple grinding tool, comprising a fixed tool 1 and a grinding block 11. A hand-cranked grinder is provided on the outside of the grinding block 11. A plurality of tool slots 2 are provided inside the fixed tool 1. The tool slots 2 are designed to tightly clamp the copper bar 3, ensuring that the relative position of the copper bar 3 and the fixed tool 1 is stable. The accuracy of the chamfer is ensured by the inclination angle of the fixed tool 1. The tool slots 2 are used to accommodate and position the copper bar 3, ensuring that the position of the copper bar 3 is stable during the processing. Copper bars 3 are provided inside the plurality of tool slots 2. Positioning blocks 4 are slidably connected to the right sides of the plurality of copper bars 3. The fixed tool 1 and the positioning block 4 can be adsorbed on the platform of the hand-cranked grinder. A plurality of fixed slots 5 are provided inside the positioning block 4. The outside of the copper bar 3 is slidably connected to the inside of the fixed slots 5. The positioning block 4 cooperates with the fixed tool 1 to further fix the position of the copper bar 3 and ensure processing accuracy. The copper bar 3 can also be adjusted by sliding along the fixed slots 5 to accommodate copper bars 3 of different lengths. The interior of the positioning block 4 is slidably connected to a squeeze plate 6, which applies pressure to the copper busbar 3, keeping it snugly in the fixing slot 5 and preventing it from moving. The exterior of the copper busbar 3 contacts the top of the squeeze plate 6, and the bottom of the squeeze plate 6 is provided with an elastic component for providing squeezing force.

[0029] Reference Figures 3 to 5The elastic component includes a plurality of sliding sleeves 7, the tops of the plurality of sliding sleeves 7 are fixedly connected to the bottom of the extrusion plate 6, and the outsides of the plurality of sliding sleeves 7 are slidably connected to sleeves 8, which provide guidance for the sliding sleeves 7 and limit their range of motion. The bottom of the sleeve 8 is fixedly connected to the inside of the positioning block 4, and the outsides of the plurality of sliding sleeves 7 are fixedly connected to a limiting ring 9, which limits the maximum range of movement of the sliding sleeves 7 and prevents them from escaping from the sleeve 8. The outside of the limiting ring 9 is slidably connected to the inside of the sleeve 8, and a spring 10 is provided inside the plurality of sliding sleeves 7, one end of the spring 10 is fixedly connected to the internal top side of the sliding sleeve 7, and the other end of the spring 10 is fixedly connected to the internal bottom side of the sleeve 8. The spring 10 stores energy and generates elastic force when released, pushing the extrusion plate 6 to apply pressure to the copper busbar 3.

[0030] Working principle: First, insert the copper busbar 3 into the tooling slot 2 inside the fixed tooling 1, and then insert it into the fixed slot 5. At this time, the extrusion plate 6 will be squeezed and displaced, and the sliding sleeve 7 will slide on the outside of the sleeve 8. Then the spring 10 will be compressed and rebounded. Then, the elastic force of the spring 10 can be used to fix and position the copper busbar 3. Then, the exposed amount of the tail end of the copper busbar 3 can be calculated, and the steel tooling can be adsorbed on the platform of the hand grinder to ensure its stability to ensure fixation during processing. Then, use the grinding block 11 on the hand grinder to cut the head of the copper busbar 3 to ensure the chamfering effect. After the processing is completed, the copper busbar 3 is turned over and inserted into the tooling slot 2 and the fixed slot 5 to continue processing the other side.
