Description

Technical Field

[0001] This invention relates to the field of copper rod processing technology, and in particular to a device for in-situ chamfering and grinding of copper rods after cutting. Background Technology

[0002] After the copper rod is cut, its end needs to be chamfered and ground before it can be finished. Most existing traditional equipment sets the copper rod cutting and end chamfering and grinding as separate workstations. After the workpiece is cut, it needs to be transferred to the grinding station for clamping and processing, which results in a dispersed process.

[0003] Currently, many integrated processing equipment uses pneumatic and electrical components such as cylinders and electromagnets to open and close the bar clamps. These electrical components have a high failure rate, and conventional clamps only achieve single-clamping. Under grinding vibration, copper bars are prone to slight slippage, leading to unstable processing quality. Adding auxiliary clamping mechanisms often requires additional drive sources, increasing the number of parts, complicating the overall machine structure, and raising manufacturing costs. Therefore, there is an urgent need for an integrated device that enables continuous operation of in-situ clamping, chamfering, grinding, and unloading of copper bars after cutting. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a copper rod cutting and in-situ chamfering and grinding device, which effectively solves the industry problems of dispersed processing steps, high failure rate of electrical and pneumatic clamps, poor clamping stability, and complex and costly addition of stabilization structures in traditional copper rod processing.

[0005] The present invention also provides a copper rod cutting and in-situ chamfering and grinding unloading device, comprising: a frame, a chamfering and grinding mechanism, a conveying and unloading mechanism, and a guide plate. The conveying and unloading mechanism is located inside the frame, the chamfering and grinding mechanism is fixedly connected to the side surface of the frame and located on one side of the conveying and unloading mechanism, and the guide plate is fixedly connected to the side surface of the frame. The conveying and unloading mechanism includes multiple sprockets, which are arranged in pairs inside the frame. The outer walls of each pair of corresponding sprockets are hinged together with a chain plate. The chain plate is assembled by hinged ends of multiple chain plates. Each chain plate is provided with a stabilizing clamping mechanism. The stabilizing clamping mechanism can automatically clamp and release the copper rod by relying on position linkage, and can further strengthen the clamping effect on the copper rod through secondary linkage during the clamping process.

[0006] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the conveying and blanking mechanism further includes two transmission rollers, which are rotatably connected side by side to the inner surface of the frame, and multiple sprockets are divided into two groups and fixedly connected to the outer wall of the transmission rollers respectively.

[0007] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the conveying blanking mechanism further includes two pulleys and a belt. The two pulleys are respectively fixedly connected to the outer walls of two transmission rollers, and the belt is sleeved on the outside of the two pulleys to realize transmission cooperation.

[0008] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, a motor is fixedly installed on the side surface of the frame, and one of the transmission rollers is connected to the output end of the motor and driven to rotate by the motor.

[0009] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the stabilizing clamping mechanism includes a through groove, two sliding blocks, and two clamping blocks. The through groove is opened on the chain plate, the two sliding blocks are respectively slidably assembled inside the through groove, and the two clamping blocks are respectively fixedly connected to the upper surface of the two sliding blocks. A return spring is fixedly connected between the two sliding blocks. The two sets of clamping blocks arranged on adjacent chain plates are positioned corresponding to each other and are used to clamp different parts of the copper rod respectively.

[0010] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the stabilizing clamping mechanism further includes a sliding groove, two sliders, and four cranks. The sliding groove is opened on the inner wall of the through groove, and the two sliders are symmetrically slidably arranged inside the sliding groove. The cranks are hinged to the top surfaces of the two sliders in pairs, and the four cranks together form a rhomboid connecting rod transmission structure. The ends of the two cranks on the same side are hinged to the bottom surfaces of the corresponding sliding blocks. By moving the two sliders towards or away from each other, the cranks can be driven to drive the transmission, thereby adjusting the opening and closing of the clamping blocks.

[0011] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the stabilizing clamping mechanism further includes a traction plate, which is disposed on the inner side of the chain belt. The traction plate has two traction grooves arranged side by side, the ends of the two traction grooves are close to each other, and the middle section of the traction grooves branches outward along the width direction of the traction plate. Multiple connecting frames are provided on the inner side of the frame, and each traction plate is fixedly connected between adjacent connecting frames. The two connecting frames located on both sides are respectively fixedly connected to the inner side wall of the frame.

[0012] According to the copper rod cutting and in-situ chamfering and grinding device of the present invention, the stabilizing clamping mechanism further includes two traction blocks, which are respectively fixedly connected to the lower surfaces of two sliders and are respectively slidably disposed inside two traction grooves. In the initial state, the two sliders are close to each other and the two sets of clamping blocks are in an open state. When the chain belt moves and drives the traction blocks to move synchronously, the groove wall of the traction groove guides the traction blocks to separate the two sliders from each other, and the crank drive drives the two clamping blocks to move towards each other to clamp the copper rod.

[0013] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the stabilizing clamping mechanism further includes a slot, a sliding frame, and two auxiliary clamping plates. The slot is opened inside the clamping block, the sliding frame is slidably assembled inside the slot, and the two auxiliary clamping plates are respectively hinged to the upper and lower sides of the sliding frame and arranged outside the slot. When the sliding frame slides into the slot, the back of the auxiliary clamping plates abuts against the outer wall of the slot, forcing the angle between the two auxiliary clamping plates to narrow, thereby achieving secondary clamping of the copper rod.

[0014] According to the copper rod cutting and in-situ chamfering and grinding blanking device of the present invention, the stabilizing clamping mechanism further includes a second return spring and a steel wire rope. The two ends of the second return spring are respectively fixedly connected to the sliding frame and the bottom of the slot. One end of the steel wire rope is fixedly connected to the back of the sliding frame, and the other end of the steel wire rope passes through the inside of the clamping block and is fixedly connected to the inner wall of the through slot. During the clamping action of the clamping block, the steel wire rope is pulled and drives the sliding frame to slide into the slot.

[0015] Beneficial effects: The copper rod cutting and in-situ chamfering and grinding unloading device of this technical solution has a stabilizing clamping mechanism that forms a purely mechanical position linkage structure with the help of traction groove, traction block and diamond crank connecting rod. When the chain belt moves, the clamping block is automatically opened and closed by the trajectory guide. There is no need for pneumatic and electrical actuators. The overall structure is simple and reliable, avoids the hidden dangers of electrical control and pneumatic circuit failures, and can be adapted to the harsh working conditions with a lot of iron filings in the grinding workshop, improving the stability of the mechanism operation. When the clamping block clamps the copper rod, the sliding frame moves through the steel wire rope, which drives the auxiliary clamping plate to deform and achieve secondary clamping. The double clamping suppresses the slight slippage of the copper rod during grinding, ensures the coaxial accuracy of the chamfer, reduces the number of parts, and lowers the overall manufacturing cost. The entire clamping and stabilization action is triggered by the same mechanical motion chain. The clamping action and the secondary clamping of the auxiliary clamping plate are synchronized, and there is no need to add an independent drive source. Attached Figure Description

[0018] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0019] Reference Figure 1-11 An embodiment of the present invention provides a device for in-situ chamfering and grinding of copper rods after cutting, comprising: Reference Figure 1 , Figure 2 , Figure 3Considering that after the copper rod is cut, the blanking and chamfering grinding stations are separated, and the secondary transfer of the workpiece is prone to positioning errors and poor continuity of processing, this overall device is set up. It includes: frame 3, chamfering grinding mechanism 1, conveying blanking mechanism, and guide plate 2. The conveying blanking mechanism is located inside the frame 3. The chamfering grinding mechanism 1 is fixedly connected to the side surface of the frame 3 and located on one side of the conveying blanking mechanism. The guide plate 2 is fixedly connected to the side surface of the frame 3. The conveying blanking mechanism includes multiple sprockets 13, which are arranged in pairs inside the frame 3. The outer walls of each pair of corresponding sprockets 13 are hinged together with a chain plate belt 12. The chain plate belt 12 is assembled by hinged assembly of multiple chain plates 11. Each chain plate 11 is equipped with a stabilizing clamping mechanism. The stabilizing clamping mechanism can realize the automatic clamping and releasing of the copper rod by relying on position linkage. In addition, it can be linked twice during the clamping process to strengthen the clamping effect of the copper rod.

[0020] Specifically: The existing chamfering and grinding mechanism 1 is mainly composed of a grinding motor, a grinding wheel and a grinding wheel feed adjustment assembly, and is used for chamfering and grinding of the end of the bar. In this device, the chamfering and grinding mechanism 1 can be equipped with MQ-60 or M3025 bar chamfering and grinding head, or a suitable model can be selected according to the specifications of the copper bar.

[0021] After the copper rod is cut, it falls into the stabilizing clamping mechanism via the guide plate 2. The copper rod is then driven by the conveying and unloading mechanism to the chamfering and grinding mechanism 1 to complete the processing. After the processing is completed, the unloading is completed. The unloading and chamfering and grinding processes are integrated into one, eliminating the need for workpiece transfer, reducing positioning deviation, and realizing continuous operation of copper rod cutting-clamping-grinding-unloading.

[0022] Reference Figure 2 , Figure 3 Considering that the chain belt 12 needs to be stably circulated and requires reliable power input, and that a simple single roller drive is prone to transmission slippage, a transmission structure of transmission roller 6, pulley 7 and belt 8 is set up; the transmission and feeding mechanism also includes two transmission rollers 6, which are connected to the inner surface of the frame 3 in parallel rotation, and multiple sprockets 13 are divided into two groups and fixedly connected to the outer wall of the transmission rollers 6 respectively; the transmission and feeding mechanism also includes two pulleys 7 and belt 8, with the two pulleys 7 fixedly connected to the outer wall of the two transmission rollers 6 respectively, and the belt 8 sleeved on the outside of the two pulleys 7 to achieve transmission cooperation; a motor 4 is fixedly installed on the side surface of the frame 3, and one of the transmission rollers 6 is connected to the output end of the motor 4 and driven to rotate by the motor 4.

[0023] Motor 4 drives one of the transmission rollers 6 to rotate, which in turn drives the other transmission roller 6 to rotate synchronously via pulley 7 and belt 8. The transmission roller 6 drives sprocket 13 to drive the chain plate belt 12 to rotate in a cycle. The two transmission rollers 6 drive the chain plate belt 12 synchronously, which ensures smooth transmission, reduces the risk of slippage, and provides stable power for the cyclic conveying of the clamping mechanism.

[0024] Reference Figure 3 , Figure 5 , Figure 6 Considering that the clamping block 9 needs to open and close, and that the copper rod is a long bar, single-point clamping is prone to swaying. Therefore, a through groove 10, a sliding block 14, a clamping block 9, and a return spring 17 are provided. The stabilizing clamping mechanism includes a through groove 10, two sliding blocks 14, and two clamping blocks 9. The through groove 10 is opened on the chain plate 11. The two sliding blocks 14 are slidably assembled inside the through groove 10. The two clamping blocks 9 are fixedly connected to the upper surface of the two sliding blocks 14. A return spring 17 is fixedly connected between the two sliding blocks 14. The two sets of clamping blocks 9 set on adjacent chain plates 12 are positioned corresponding to each other and are used to clamp different parts of the copper rod respectively.

[0025] The sliding block 14 can slide relative to the through groove 10, driving the clamping block 9 to open and close; the return spring 17 provides the opening and returning force, and the two sets of clamping blocks 9 clamp the copper rod at different positions; the copper rod is constrained at multiple points, reducing deflection and shaking during processing, and the return spring 17 ensures that the clamping block 9 can automatically spring back and open, which is convenient for loading and unloading.

[0026] Reference Figure 6 , Figure 9 Considering the high sliding resistance of the direct-drive sliding block 14, it is necessary to convert the displacement of the slider 15 into the opening and closing action of the clamping block 9. Therefore, a sliding groove 19, slider 15, and a rhomboid connecting rod transmission structure composed of four cranks 18 are provided. The stabilizing clamping mechanism also includes a sliding groove 19, two sliders 15, and four cranks 18. The sliding groove 19 is opened on the inner wall of the through groove 10, and the two sliders 15 are symmetrically slidably arranged inside the sliding groove 19. The cranks 18 are hinged to the top surfaces of the two sliders 15 in pairs. The four cranks 18 together form a rhomboid connecting rod transmission structure. The ends of the two cranks 18 on the same side are hinged to the bottom surface of the corresponding sliding block 14. By moving the two sliders 15 towards or away from each other, the cranks 18 can be driven to drive the transmission, thereby adjusting the opening and closing of the clamping block 9.

[0027] The two sliders 15 undergo relative displacement within the slide groove 19, and the motion is converted through the rhomboid crank 18 connecting rod, driving the sliding block 14 and the clamping block 9 to complete the opening and clamping actions; the rhomboid connecting rod mechanism has smooth transmission and good displacement amplification effect, efficiently converting the horizontal motion of the slider 15 into the clamping motion of the clamping block 9, thus improving the stability of the action response.

[0028] Reference Figure 4Considering that if the trajectory component moves cyclically with the chain belt 12, it will increase the number of follower parts and aggravate wear, a fixed traction plate 24 and traction groove 23 are set. The traction plate 24 is fixed to the inner side of the frame 3 by the connecting frame 5. The stabilizing clamping mechanism also includes a traction plate 24, which is located inside the chain belt 12. The traction plate 24 has two traction grooves 23 arranged side by side. The ends of the two traction grooves 23 are close to each other, and the middle section of the traction groove 23 branches outward along the width direction of the traction plate 24. Multiple connecting frames 5 are set on the inner side of the frame 3. Each traction plate 24 is fixedly connected between adjacent connecting frames 5. The two connecting frames 5 located on both sides are fixedly connected to the inner side wall of the frame 3.

[0029] The traction plate 24 is fixed and kept stationary by the connecting frame 5, and the predetermined trajectory of the traction groove 23 provides positional constraints for the movement of the clamp. The trajectory component is fixed and does not move with the clamp in a cyclical manner, reducing the number of moving parts, reducing wear, and simplifying the overall structure of the machine.

[0030] Reference Figure 6 , Figure 9 Considering the need for purely mechanical position triggering clamping without electrical or pneumatic components, a traction block 16 is designed to cooperate with the traction groove 23. The stabilizing clamping mechanism also includes two traction blocks 16, which are fixedly connected to the lower surfaces of the two sliders 15 and slidably disposed inside the two traction grooves 23. In the initial state, the two sliders 15 are close to each other, and the two sets of clamping blocks 9 are in an open state. When the chain belt 12 moves and drives the traction blocks 16 to move synchronously, the groove wall of the traction groove 23 guides the traction blocks 16 to separate the two sliders 15 from each other. The crank 18 drives the two clamping blocks 9 to move towards each other to clamp the copper rod.

[0031] The chain belt 12 moves and drives the traction block 16 to slide along the fixed traction groove 23. The traction groove 23 forces the two sliders 15 to produce relative displacement, and drives the clamping block 9 to clamp the copper rod through the diamond crank 18 connecting rod. Pure mechanical automatic clamping is achieved by relying on the position trajectory, eliminating the need for cylinders and electromagnets, adapting to grinding conditions with a lot of iron filings, and reducing the probability of failure.

[0032] Reference Figure 10 , Figure 11Considering that the copper rod is prone to slight slippage under grinding vibration due to only a single clamping, a secondary clamping is required on the basis of the initial clamping. Therefore, a slot 20, a sliding frame 22, and auxiliary clamping plates 21 are set. The stabilizing clamping mechanism also includes a slot 20, a sliding frame 22, and two auxiliary clamping plates 21. The slot 20 is opened inside the clamping block 9. The sliding frame 22 is slidably assembled inside the slot 20. The two auxiliary clamping plates 21 are respectively hinged to the upper and lower sides of the sliding frame 22 and arranged outside the slot 20. When the sliding frame 22 slides into the slot 20, the back of the auxiliary clamping plate 21 abuts against the outer wall of the slot 20, forcing the angle between the two auxiliary clamping plates 21 to narrow, thereby achieving a secondary clamping of the copper rod.

[0033] The sliding frame 22 retracts into the slot 20, and the back of the auxiliary clamping plate 21 is squeezed by the side wall of the slot 20, causing the included angle to narrow and deform, further tightening the copper rod; a second clamping is achieved on the basis of the initial clamping, increasing the clamping force, suppressing the slippage of the copper rod caused by grinding vibration, and improving the coaxial accuracy of chamfering.

[0034] Reference Figure 8 Considering that the secondary clamping action needs to be linked with the clamping action of the fixture, no additional drive source is added. At the same time, the auxiliary clamping plate 21 can automatically reset after processing. Therefore, a second reset spring 26 and a steel wire rope 25 are set. The stabilizing clamping mechanism also includes a second reset spring 26 and a steel wire rope 25. The two ends of the second reset spring 26 are fixedly connected to the sliding frame 22 and the bottom of the slot 20, respectively. One end of the steel wire rope 25 is fixedly connected to the back of the sliding frame 22, and the other end of the steel wire rope 25 passes through the inside of the clamping block 9 and is fixedly connected to the inner wall of the through groove 10. During the clamping action of the clamping block 9, the steel wire rope 25 is pulled and drives the sliding frame 22 to slide into the slot 20.

[0035] The clamping block 9 clamps and displaces, causing the wire rope 25 to be pulled, dragging the sliding frame 22 to compress the reset spring 26 and slide inward; after the clamp is released, the reset spring 26 drives the sliding frame 22 to reset, and the auxiliary clamping plate 21 opens accordingly; the clamping action triggers the secondary clamping, requiring no additional drive source, with fewer parts, low cost, and automatic reset cycle operation.

[0036] In summary, the improvement of this embodiment lies in: The stabilizing clamping mechanism uses the traction groove 23, traction block 16 and diamond crank 18 to form a purely mechanical position linkage structure. When the chain belt 12 moves, the clamping block 9 is automatically opened and closed through the trajectory guide. There is no need for pneumatic or electrical actuators. The overall structure is simple and reliable, avoiding the potential faults of electrical control and pneumatic circuits. It can adapt to the harsh working conditions with a lot of iron filings in the grinding workshop and improve the stability of the mechanism. When clamping block 9 clamps the copper rod, it drives the sliding frame 22 to move through wire rope 25, which in turn drives the auxiliary clamping plate 21 to deform and achieve secondary clamping. The double clamping suppresses the slight slippage of the copper rod during grinding, ensures the coaxial accuracy of the chamfer, reduces the number of parts, and lowers the overall manufacturing cost. The entire clamping and stabilization action is triggered by the same mechanical motion chain. The clamping action is synchronized with the secondary clamping of the auxiliary clamping plate 21, so there is no need to add an independent drive source.

[0037] Working principle: When the copper rod is cut and then beveled and ground in place, the motor 4 drives the transmission roller 6 to rotate, and through the pulley 7 and belt 8, it drives the two sets of sprockets 13 to rotate, so that the chain plate belt 12 carries the stabilizing clamping mechanism on each chain plate 11 to continuously circulate. After the copper rod is cut, it falls between the open clamping blocks 9 through the guide plate 2 and moves with the chain belt 12. The traction block 16 at the bottom of the slider 15 slides along the trajectory of the traction groove 23 on the fixed traction plate 24 inside the frame 3. The trajectory guides the two sets of sliders 15 to move in opposite directions. Through the diamond-shaped connecting rod structure composed of four sets of cranks 18, the sliding block 14 is driven to slide in the through groove 10. Overcoming the elastic force of the return spring 17, the clamping blocks 9 on both sides close together to complete the initial clamping. During the clamping process, the displacement of the clamping block 9 pulls the steel wire rope 25, causing the sliding frame 22 to compress the reset spring 26 and slide into the slot 20, forcing the auxiliary clamping plate 21 to be pressed against the slot wall and narrow the included angle, achieving synchronous secondary clamping and stabilization, and effectively fixing the copper rod. Subsequently, the chamfering and grinding mechanism 1 completes the end grinding operation of the copper rod. After the processing is completed, the traction block 16 is removed from the limit track, and the first reset spring 17 and the second reset spring 26 rebound in sequence. The clamping block 9 and the auxiliary clamping plate 21 open synchronously to complete the automatic unloading. The entire process relies on pure mechanical position linkage to realize continuous automated clamping, grinding and unloading operations.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
