Description

Technical Field

[0001] This utility model relates to the field of copper busbar processing technology, specifically to a fixture for removing burrs from copper busbars. Background Technology

[0002] Copper busbars, as an important conductive material, are widely used in power systems, new energy equipment, and precision electronic components. During the stamping, shearing, or milling process of copper busbars, burrs and flash are often generated on their edges. These burrs not only affect the appearance quality of the workpiece but may also reduce conductivity and even cause short circuits or equipment damage during use due to burr detachment. Therefore, for copper busbar workpieces with high-quality requirements, burr and flash removal is an essential process.

[0003] Currently, the main method for removing burrs from copper busbars in the industry still relies on traditional manual cutting or filing. However, manual burr removal depends on the operator's experience and skill level, and processing a single piece takes a long time, making it difficult to meet the needs of mass production. Manual trimming is prone to uneven edges of the copper busbars due to uneven force or operational errors, which may even cause secondary damage, affecting the consistency of the workpieces and the yield rate. Furthermore, manual operation is difficult to automate, which restricts the improvement of production efficiency. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a fixture for cutting off the burrs of copper busbars.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A fixture for removing burrs from copper busbars includes a table, on which a placement plate is slidably disposed. The placement plate forms a positioning groove for placing a workpiece. Copper busbars are exposed on both sides of the workpiece, and a limiting groove for inserting the copper busbars is formed in the positioning groove. A mounting bracket is disposed on the table, and the mounting bracket is provided with a clamping and positioning component for clamping the workpiece, and a cutting component for cutting the burrs from the copper busbars. The clamping and positioning assembly includes a first driving unit, a clamping and positioning plate connected to the output unit of the first driving unit, and a positioning unit disposed on the clamping and positioning plate. The cutting assembly includes a second driving unit, a mounting plate connected to the output unit of the second driving unit, and a plurality of cutting blocks disposed on the mounting plate. The cutting blocks move up and down in conform to the outer contour of the copper busbar.

[0006] Preferably, the positioning unit includes a positioning rod, and an insertion groove for inserting the positioning rod is formed on the workpiece. With the above improvements, when performing burr trimming, the first driving unit drives the clamping positioning plate to descend, so that the positioning rod is inserted into the positioning groove of the workpiece, thereby ensuring the stability of the workpiece during the trimming process and avoiding workpiece displacement during the trimming process.

[0007] Preferably, the positioning unit further includes an elastic element, which abuts against the surface of the workpiece. Through the above improvements, the elastic element abuts against the surface of the workpiece during cutting, further improving the stability of the workpiece placement.

[0008] Preferably, the cutting block includes a clamping part and cutting parts disposed on both sides of the clamping part. The second drive unit drives the mounting plate to descend so that the clamping part abuts against the surface of the copper busbar and forces the cutting parts to slide downward in accordance with the contour of the copper busbar. With the above improvements, when the workpiece is placed in place, it will be clamped and positioned by the clamping and positioning assembly, and the second drive unit will drive the entire cutting block to descend. The clamping part of the cutting block will press against the upper end face of the copper busbar, and the burrs on both sides of the copper busbar will be removed by the descent of the cutting parts.

[0009] Preferably, the cutting part is detachably disposed on both sides of the clamping part, and the clamping part has threaded connection holes on both sides, and the cutting part has mounting holes that are opposite to the threaded connection holes. With the above improvements, the cutting part will wear out after long-term use. The threaded connection holes and mounting holes are used to make the cutting part quick to disassemble and replace.

[0010] Preferably, a guide block is provided on the table surface, and a sliding groove is formed on the guide block for the placement plate to slide. A positioning switch is provided at the end of the sliding groove opposite to the material discharge direction of the placement plate. When the cutting component performs burr removal, the placement plate abuts against the positioning switch. Through the above improvements, by using the cooperation between the placement plate and the guide block, the placement plate can slide within the sliding groove of the guide block, improving the stability of the placement plate during movement. Furthermore, cutting is only performed when the placement plate abuts against the positioning switch, ensuring the position of the placement plate and improving the burr removal quality.

[0011] Preferably, the sliding groove is provided with travel limit blocks at both ends, and the placement plate abuts against the travel limit blocks to restrict the placement plate from continuing to slide. With the above improvement, when the placement plate slides to a certain travel distance, the placement plate will abut against the travel limit blocks, thereby limiting the sliding travel of the plate, preventing the placement plate from leaving the sliding groove, and ensuring the cutting position of the placement plate.

[0012] Preferably, the two sides of the limiting groove form a collection channel for the flash of the workpiece to fall into, and the collection channel is arranged opposite to the cutting part. With the above improvement, the flash that falls off during cutting will fall into the collection channel, thereby collecting and cleaning the flash.

[0013] Preferably, a sliding guide block is provided on the platform, and the bottom of the placement plate forms a guide groove for the sliding guide block to be inserted. Through the above improvements, the stability of the placement plate during the sliding process is further improved by using the sliding guide block and the guide groove to cooperate, and the placement plate is prevented from deviating during the sliding process.

[0014] Preferably, a positioning sensor is embedded in the side wall of the guide groove, and a release groove is formed on the sliding guide block for releasing the control end of the positioning sensor. The placement plate has a cutting position and a sliding position. When the placement plate is in the cutting position, the positioning sensor is placed in the release groove. When the placement plate is in the sliding position, the control end of the positioning sensor abuts against the sliding guide block. Through the above improvements, the flash will only be cut when the positioning sensor is placed in the release groove, so as to ensure the accuracy of flash cutting.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: By setting a placement plate on the table, and forming a positioning groove for placing the workpiece and a limiting groove for inserting the copper busbar on the placement plate, and setting a mounting bracket on the table, with a clamping and positioning component for clamping the workpiece and a cutting component for trimming the burrs of the copper busbar, the workpiece is simply placed into the positioning groove and clamped by the clamping and positioning component, while the cutting component trims the burrs of the copper busbar. Compared with manual cutting, this method not only greatly increases cutting efficiency and cutting quality, but also reduces labor costs. Attached Figure Description

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.

These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0019] like Figure 1-10 As shown, a fixture for removing the burrs of a copper busbar 3 includes a table 1, a placement plate 2 slidably disposed on the table 1, a positioning groove 4 formed on the placement plate 2 for placing the workpiece, copper busbars 3 exposed on both sides of the workpiece, and a limiting groove 5 for inserting the copper busbars 3 within the positioning groove 4, a mounting bracket 6 disposed on the table 1, and a clamping and positioning component 7 for clamping the workpiece and a cutting component 8 for cutting the burrs of the copper busbar 3 on the mounting bracket 6.

[0020] Specifically, the clamping and positioning assembly 7 includes a first driving unit 1.1, a clamping and positioning plate 1.2 connected to the output unit of the first driving unit 1.1, and a positioning unit 1.3 disposed on the clamping and positioning plate 1.2. The cutting assembly 8 includes a second driving unit 1.4, a mounting plate 1.5 connected to the output unit of the second driving unit 1.4, and a plurality of cutting blocks 1.6 disposed on the mounting plate 1.5. The cutting blocks 1.6 move up and down in conform to the outer contour of the copper busbar 3.

[0021] During the entire flash trimming process, the placement plate 2 can be pulled out, and the workpiece can be placed into the positioning groove 4 so that the copper busbar 3 on the workpiece is placed into the limiting groove 5. Then, the placement plate 2 is pushed into the designated position, and the workpiece is pressed by the clamping positioning component 7. The trimming component 8 trims the flash of the copper busbar 3. Compared with manual trimming, not only is the trimming efficiency greatly increased, but the trimming quality is also greatly increased, and the labor cost is reduced.

[0022] Preferably, a pull handle 6.1 is connected to the placement plate 2 to improve the convenience of use.

[0023] Preferably, a lifting guide rod 6.2 is provided on the platform 1, and the pressing positioning plate 1.2 and the mounting plate 1.5 slide up and down along the lifting guide rod 6.2 to ensure the stability of the pressing positioning plate 1.2 and the mounting plate 1.5 during the up and down movement.

[0024] like Figures 1 to 5 As shown, as a further explanation of the embodiment of the positioning unit 1.3, the positioning unit 1.3 includes a positioning rod 2.1, and an insertion groove 2.2 is formed on the workpiece for the positioning rod 2.1 to be inserted. When the flash is cut, the first driving unit 1.1 drives the clamping positioning plate 1.2 to descend, so that the positioning rod 2.1 is inserted into the positioning groove 4 of the workpiece, thereby ensuring the stability of the workpiece during the cutting process and avoiding the workpiece from shifting during the cutting process.

[0025] Furthermore, the positioning unit 1.3 also includes an elastic element 2.3. During the cutting process, the elastic element 2.3 abuts against the surface of the workpiece to prevent the workpiece from shifting during the cutting process, thereby further improving the stability of the workpiece placement.

[0026] like Figures 1 to 8 As shown, in a further explanation of the embodiment of the cutting block 1.6, the cutting block 1.6 includes a clamping part 3.1 and cutting parts 3.2 disposed on both sides of the clamping part 3.1. When the workpiece is placed in place, the second drive unit 1.4 drives the mounting plate 1.5 to descend, so that the clamping part 3.1 abuts against the surface of the copper busbar 3 and forces the cutting part 3.2 to slide downward in line with the contour of the copper busbar 3. The workpiece will be clamped and positioned under the action of the clamping and positioning assembly 7, and the second drive unit 1.4 drives the entire cutting block 1.6 to descend, and the cutting part 3.2 descends to remove the burrs on both sides of the copper busbar 3.

[0027] During the flash removal process, the clamping part 3.1 of the cutting block 1.6 will press against the upper end face of the copper busbar 3 to ensure the stability of the copper busbar 3.

[0028] Furthermore, the cutting part 3.2 is detachably provided on both sides of the clamping part 3.1, and the clamping part 3.1 has threaded connection holes 3.3 on both sides, and the cutting part 3.2 has mounting holes 3.4 that are opposite to the threaded connection holes 3.3.

[0029] After prolonged use, the cutting part 3.2 will wear out. By using the threaded connection hole 3.3 and the mounting hole 3.4, the cutting part 3.2 can be quickly disassembled and replaced.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, a further explanation of the sliding implementation of the placement plate 2 is provided: a guide block 4.1 is provided on the table surface 1, and a sliding groove 4.2 is formed on the guide block 4.1 for the placement plate 2 to slide. A positioning switch 4.3 is provided at the end of the sliding groove 4.2 opposite to the material discharge direction of the placement plate 2. When the cutting component 8 performs burr removal, the placement plate 2 abuts against the positioning switch 4.3. By cooperating with the guide block 4.1, the placement plate 2 can slide within the sliding groove 4.2 of the guide block 4.1, improving the stability of the placement plate 2 during movement. Cutting is only performed when the placement plate 2 abuts against the positioning switch 4.3, ensuring the position of the placement plate 2 and improving the cutting quality of the burr.

[0031] Furthermore, travel limit blocks 4.4 are provided at both ends of the sliding groove 4.2. The placement plate 2 abuts against the travel limit blocks 4.4 to restrict the placement plate 2 from continuing to slide. When the placement plate 2 slides to a certain travel distance, the placement plate 2 will abut against the travel limit blocks 4.4, thereby limiting the sliding travel of the plate, preventing the placement plate 2 from leaving the sliding groove 4.2, and ensuring the cutting position of the placement plate 2.

[0032] Furthermore, the limiting groove 5 forms a collection channel 4.5 on both sides for the flash to fall into, and the collection channel 4.5 is set opposite to the cutting part 3.2. The flash that falls off during cutting will fall into the collection channel 4.5, thereby collecting and cleaning the flash.

[0033] The collection channel 4.5 is connected to a suction unit, which can remove the cut-off burrs from the placement plate 2, thereby ensuring that the placement plate 2 is clean and tidy.

[0034] Preferably, the platform 1 has a connecting hole 6.3 that forms a connecting collection channel 4.5.

[0035] In addition, a sliding guide block 4.6 is provided on the platform 1, and the bottom of the placement plate 2 is formed with a guide groove 4.7 for the sliding guide block 4.6 to be inserted. By using the sliding guide block 4.6 and the guide groove 4.7 to cooperate, the stability of the placement plate 2 during the sliding process is further improved, and the placement plate 2 is prevented from deviating during the sliding process.

[0036] like Figure 9 , Figure 10 As shown, in some other embodiments, a position sensor 5.1 is embedded in the side wall of the guide groove 4.7, and a release groove 5.2 is formed on the sliding guide block 4.6 for releasing the control end of the position sensor 5.1. The placement plate 2 has a cutting position and a sliding position. When the placement plate 2 is in the cutting position, the position sensor 5.1 is placed in the release groove 5.2. When the placement plate 2 is in the sliding position, the control end of the position sensor 5.1 abuts against the sliding guide block 4.6. Only when the position sensor 5.1 is placed in the release groove 5.2 will the flash be cut to ensure the accuracy of the flash cutting.

[0037] Preferably, a sliding ramp 53 is formed within the release groove 5.2, thereby improving the smoothness of the control end of the positioning sensor 5.1 during the sliding process.

[0038] Preferably, the actuating end of the position sensor 5.1 is fitted with a sliding sleeve, and the sliding sleeve is made of wear-resistant material.

[0039] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
