Description

Technical Field

[0001] This utility model relates to the field of copper electrode processing technology, specifically to a device for coaxial processing of inner and outer holes of copper electrodes. Background Technology

[0002] Copper terminals are core conductive connection components in fields such as new energy vehicle battery packs and energy storage systems. They are usually made of high-purity copper (T2, TU2) or copper alloys (such as copper-chromium-zirconium alloy). Their function is to realize electrical connection, current transmission and mechanical fixation between battery modules through the internal and external hole structure.

[0003] In the current processing of copper poles, the clamping fixtures are limited and cannot be well adapted to clamping copper poles of different sizes, models, and shapes. Existing three-jaw chucks or V-blocks require adjustment of the clamping point position or clamping components for each model, which is inconvenient due to frequent changes and long processing times.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a device for coaxial machining of inner and outer holes of copper pole posts, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a coaxial machining device for inner and outer holes of copper pole posts, including a housing 10 and a plurality of guide channels 101 arranged in a ring array about its axial direction, extending radially and vertically through it. The housing 10 is provided with a driving mechanism and a filtering mechanism, and the guide channels 101 are provided with a sealing mechanism. The driving mechanism includes:

[0007] Multiple guide channels 2 102 are formed on the bottom inner wall of the housing 10. The multiple guide channels 2 102 correspond one-to-one with the multiple guide channels 101 and are parallel to each other. The same scissor lift 13 slides in the multiple guide channels 2 102. A vertical fixing post 20 is rotatably set at the top of the scissor lift 13 corresponding to the position of the guide channel 2 102. The end of the fixing post 20 away from the scissor lift 13 extends into the guide channel 101.

[0008] The limiting block 11 is fixed to the top of the fixing column 20, and its length direction is consistent with the radial direction of the housing 10. A parting vise is fixed to one end of the limiting block 11 near the axis of the housing 10. A fixing tube 12 is fixed to the top of the limiting block 11. A liquid storage tank 14 is fixed at the center of the housing 10. A telescopic hose is connected to the outer arc wall of the liquid storage tank 14. The end of the telescopic hose away from the liquid storage tank 14 is fixed to the side wall of the fixing column 20. The fixing column 20 has a hollow structure inside. The fixing column 20 connects the fixing tube 12 and the telescopic hose. The liquid storage tank 14 is filled with cutting fluid.

[0009] Furthermore, a guide block slides within the second guide channel 102, and an electric push rod is fixed to the side wall of one of the guide blocks. The electric push rod is embedded within the second guide channel 102. Multiple vertically penetrating drainage grooves are provided at the center of the top of the housing 10. Storage grooves are provided on both sides of the first guide channel 101 along the circumference of the housing 10. The sealing mechanism includes multiple sealing blocks 21 that are linearly distributed at equal intervals along the length of the first guide channel 101 within the storage grooves. The horizontal cross-section of the sealing block 21 is a right trapezoid, and the inclined surface faces the inside of the storage groove. A guide groove is provided at the corner of the sealing block 21 away from the inner wall of the storage groove. The guide groove penetrates the sealing block 21 along the length of the first guide channel 101.

[0010] Furthermore, at the horizontal height position corresponding to the guide channel 101, the fixed column 20 has two wedge blocks 23 with the same structure fixed at both ends along the length of the guide channel 101. The end of the wedge block 23 away from the fixed column 20 is an inclined surface. A wedge block 22 is fixed in the storage groove. The horizontal cross section of the wedge block 22 is an isosceles right triangle. The inclined surface of the wedge block 22 and the inclined surface at the end of the wedge block 23 slide against each other. A return spring 211 is fixed on the side wall of the sealing block 21 near the storage groove. The end of the return spring 211 away from the sealing block 21 is fixed to the inner wall of the storage groove.

[0011] Furthermore, a sliding channel is radially provided on the outer arc wall of the liquid storage tank 14 along the shell 10. A horizontal baffle 30 is fixed on the inner wall of the bottom of the sliding channel. A vertically penetrating placement channel one is provided at the center of the baffle 30.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The drive mechanism drives multiple fixed columns to move synchronously in a centripetal or centrifugal motion, achieving stepless adjustment of the clamping diameter without the need for additional fixture replacement. When the fixed column moves, the wedge block pushes the sealing block to compress the reset spring, so that the sealing block fits tightly against the outer wall of the pole post, preventing flying debris from entering the housing.

[0014] 2. By delivering the cutting fluid from the storage tank through the hollow fixed column to the fixed pipe, it is directly sprayed onto the contact area between the drill bit and the pole post. The cutting fluid carrying copper chips flows from the drain trough into the storage tank, where it is intercepted by the filter screen. The second baffle placement channel is aligned with the chip discharge trough of the shell, and the copper chips are discharged under gravity. The filter screen is automatically switched for cleaning by rotating rollers. Attached Figure Description

[0025] 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.

[0026] Please see the appendix Figure 1 To be continued Figure 6This utility model provides a coaxial machining device for inner and outer holes of copper pole posts: it includes a housing 10 and multiple guide channels 101 arranged in a ring array about its axial direction, extending radially and vertically through it. The housing 10 is provided with a driving mechanism and a filtering mechanism, and the guide channels 101 are provided with a sealing mechanism. The driving mechanism includes:

[0027] Multiple guide channels 2 102 are formed on the bottom inner wall of the housing 10. The multiple guide channels 2 102 correspond one-to-one with the multiple guide channels 101 and are parallel to each other. The same scissor lift 13 slides in the multiple guide channels 2 102. A vertical fixing post 20 is rotatably set at the top of the scissor lift 13 corresponding to the position of the guide channel 2 102. The end of the fixing post 20 away from the scissor lift 13 extends into the guide channel 101.

[0028] A limiting block 11 is fixed to the top of the fixing column 20, and its length direction is consistent with the radial direction of the housing 10. A parting vise is fixed to one end of the limiting block 11 near the axis of the housing 10. A fixing tube 12 is fixed to the top of the limiting block 11. A liquid storage tank 14 is fixed at the center of the housing 10. A telescopic hose is connected to the outer arc wall of the liquid storage tank 14. The end of the telescopic hose away from the liquid storage tank 14 is fixed to the side wall of the fixing column 20. The fixing column 20 has a hollow structure inside. The fixing column 20 connects the fixing tube 12 and the telescopic hose. The liquid storage tank 14 is filled with cutting fluid.

[0029] A guide block slides in the second guide channel 102, and an electric push rod is fixed on the side wall of one of the guide blocks. The electric push rod is embedded in the second guide channel 102. Multiple vertically penetrating drainage grooves are opened at the center of the top of the housing 10.

[0030] The guide channel 101 has storage slots on both sides of the housing 10 circumferentially. The sealing mechanism includes multiple sealing blocks 21 that are linearly distributed at equal intervals along the length of the guide channel 101 in the storage slots. The horizontal cross section of the sealing block 21 is a right trapezoid, and the inclined surface is set towards the inside of the storage slot. A guide groove is provided at the corner of the sealing block 21 away from the inner wall of the storage slot. The guide groove is set through the sealing block 21 along the length of the guide channel 101.

[0031] It should be noted that the scissor lift 13 is annular. When the electric push rod is started, the guide block moves along the guide channel 102 toward the axis of the housing 10, pushing the scissor lift 13 to extend or retract. The extension and retraction of the scissor lift 13 adjusts the position of multiple fixed columns 20 to accommodate copper poles of different diameters or shapes. A drilling device is coaxially provided at the top of the housing, which will not be described in detail here.

[0032] The parting vise is an existing technology designed to better limit the movement of copper poles of different shapes. When the fixed pole 20 moves, the inclined surfaces of the two wedge blocks 23 at both ends slide against the inclined surfaces of the first wedge block 22 in the storage groove, pushing the sealing block 21 to overcome the elastic force of the return spring 211 and slide into the storage groove. The sealing block 21 closes the guide channel 101 to prevent flying debris from entering.

[0033] The cutting fluid in the storage tank 14 is sprayed out through the telescopic hose, the fixed column 20 and then through the fixed pipe 12. The outlet of the fixed pipe 12 is aligned with the contact area between the drill bit and the copper electrode post, directly cooling the cutting point and flushing away copper chips. The drain trough set at the center of the top of the housing 10 allows the cutting fluid to flow into the storage tank 14 through it.

[0034] Please see the appendix Figure 1 To be continued Figure 6 The present invention provides a technical solution: at the horizontal height position of the fixed column 20 corresponding to the guide channel 101, both ends of the guide channel 101 are fixed with the same structure of wedge block 23. The end of the wedge block 23 away from the fixed column 20 is an inclined surface. A wedge block 22 is fixed in the storage groove. The horizontal cross section of the wedge block 22 is an isosceles right triangle. The inclined surface of the wedge block 22 and the inclined surface at the end of the wedge block 23 slide against each other. A return spring 211 is fixed on the side wall of the sealing block 21 near the storage groove. The end of the return spring 211 away from the sealing block 21 is fixed to the inner wall of the storage groove.

[0035] A sliding channel is provided on the outer arc wall of the liquid storage tank 14, which runs radially through the shell 10. A horizontal baffle 30 is fixed on the inner wall of the bottom of the sliding channel. A vertically penetrating placement channel is provided at the center of the baffle 30. The placement channel is coaxially arranged with the drain groove on the inner wall of the top of the shell 10.

[0036] The baffle 30 has inclined surfaces at both ends along its length direction, the inclined surfaces are inclined toward the liquid storage tank 14, and a vertical through-hole storage channel 2 is opened on the side of the inclined surface near the liquid storage tank 14. The bottom of the shell 10 is provided with a chip removal groove at the position corresponding to the storage channel 2 on the outside of the liquid storage tank 14. The top of the baffle 30 is provided with a horizontal filter screen 31, and rotating rollers are sleeved on both ends of the filter screen 31 along the length direction of the baffle 30.

[0037] It should be noted that: the cutting fluid flows through the filter screen 31 at the top of the baffle 30 to intercept copper shavings. The rotating roller can be driven by an external motor, which in turn drives the filter screen 31 to rotate and dynamically replace the filter screen 31, preventing copper shavings from accumulating and clogging the mesh. When the filter surface rotates to the bottom, the copper shavings naturally fall to the top of the baffle 30 and slide down the inclined surface of the top of the baffle 30 with the assistance of the filter screen 31 from the second storage channel to the chip discharge trough for discharge.

[0038] It is understandable that the baffle 30 is positioned to avoid the fixed post 20.

[0039] Working principle:

[0040] The electric push rod drives the guide block to move along the guide channel 102, which in turn causes the scissor lift 13 to extend or retract, and adjusts the position of the fixed column 20 to adapt to different copper poles. When the fixed column 20 moves, its wedge block 23 slides against the inclined surface of the wedge block 22 in the storage slot, pushing the sealing block 21 to overcome the elastic force of the return spring 211 and slide into the storage slot, thus closing the guide channel 101 to prevent flying debris.

[0041] After the parting vise limits the copper electrode, the drilling equipment performs the machining. The cutting fluid in the storage tank 14 is sprayed through the telescopic hose and the hollow channel of the fixed column 20, and then sprayed through the fixed pipe 12 onto the contact area between the drill bit and the copper electrode to cool and flush away copper chips. The cutting fluid flows into the outer cavity of the storage tank 14 through the drain trough, and flows through the filter screen 31 at the top of the baffle 30 to intercept copper chips. The rotating roller drives the filter screen 31 to rotate to prevent blockage. The copper chips slide down the inclined surface of the baffle 30 through the second placement channel to the chip discharge trough and are discharged, realizing the recycling of the cutting fluid.
