Description

Technical Field

[0001] The invention belongs to the technical field of burr cleaning, in particular to a device for cleaning burr of copper alloy welding parts. Background Art

[0002] The copper alloy welding burr cleaning device is a device specially used to remove burrs, flash and other defects on the surface of copper alloy welding parts. Its function is to clean the burrs around the weld to ensure the dimensional accuracy and surface quality of the parts and improve the performance and reliability of the parts.

[0003] In the prior art, a rectangular copper block is formed after two rectangular copper plates are welded. When cleaning the burrs at the welding place of the copper block, the copper block is first placed on a workbench, and then the motor is started to drive the sanding belt driving wheel to rotate through the transmission device, so that the sanding belt moves at a certain linear speed, and the copper block is pressed against the high-speed moving sanding belt through a mechanical device. The abrasive grains on the surface of the sanding belt rub against the surface of the welding place of the copper block, and the surface of the welding place of the copper block is cut, ground and polished to remove the burrs on the surface of the welding place of the copper block, so that the welding surface of the copper block reaches the required smoothness and precision.

[0004] The prior art still has some deficiencies in actual use. The burrs at the welding joints of the copper block are removed by sanding with a sanding belt. Since the length and width of the rectangular copper block are different, in order to completely grind the burrs at the welding joints, it is necessary to move the sanding belt grinding device during grinding. However, during the movement, the device will inevitably vibrate, causing the distance of the sanding belt grinding welding joint to fluctuate, resulting in excessive grinding, thereby causing the non-target area near the welding joint of the copper block to be over-ground, thereby destroying the original dimensional accuracy and surface integrity of the copper block.

[0005] To this end, the present invention provides a device for cleaning welding burrs of copper alloy parts. Summary of the invention

[0013] Preferably, a first motor is fixedly connected to the top of the displacement plate. The displacement plate is in threaded connection with the lead screw and slides on two guide rods, enabling the displacement plate to move only linearly.

[0014] Preferably, the output end of the first motor is fixed to the second rotating shaft. The second rotating shaft slides in the first guide groove, and the slider slides in the second guide groove. The top of the connecting plate abuts against the bottom of the displacement plate, enabling the connecting plate to move only horizontally.

[0015] Preferably, a distance-determining assembly is provided at the top of each fixed rod. The distance-determining assembly includes a fixed plate. One side of the fixed plate is fixedly connected to a telescopic rod. One end of the telescopic rod is slidably connected to a telescopic sleeve. A second spring is fixedly connected between the telescopic rod and the telescopic sleeve. One end of the telescopic sleeve is fixedly connected to a distance-determining block.

[0016] Preferably, the first contact is on the movement track of the second contact. When the telescopic sleeve slides, the first contact and the second contact will abut against each other.

[0017] The beneficial effects of the present invention are as follows: 1. By clockwise rotation of the guide post, the first rotating sleeve is relatively fixed under the action of the rotating plate, causing the copper block to rotate by 90 degrees, so that the other half of it is in the grinding position, completing its rotation. At the same time, through the rotation of the multiplier rod, the gear rod drives the rack to move synchronously, enabling the sand belt on the displacement box to quickly move away from the copper block, preventing the problem that the copper block collides with the grinding device during its rotation due to different copper block sizes. By reverse movement of the guide post, when the copper block is stationary, the displacement box moves in the reverse direction, making the sand belt on it fit the welding joint of the copper block, realizing the fit of the sand belt to the welding joint of the copper block after its rotation.

[0018] 2. By rotation of the lead screw to drive the displacement plate to move, under the action of the connecting plate, when the displacement plate moves, the displacement plate drives the second rotating shaft to move towards the direction close to the second guide groove, and the slider moves away from the lead screw under the action of the connecting plate, thereby adjusting the length of the sand belt between the two second rotating sleeves, making the length of the sand belt greater than the side length of the rectangle with which it abuts, facilitating the one-time grinding of the welding burrs of the copper block, and thus improving the grinding effect.

[0019] 3. When the sand belt approaches the welding position of the copper block, the distance - determining block will first abut against the surface of the copper block. As the sand belt continues to move, the telescopic sleeve slides towards the fixed plate and elastically compresses the second spring until the first contact point abuts against the second contact point, keeping a distance between the sand belt and the copper block to prevent direct contact, which may cause friction with the welding position of the copper block when adjusting the length of the sand belt. Along with the adjustment of the length of the sand belt, the distance - determining assembly is driven to move synchronously. When the distance - determining block no longer abuts against the surface of the copper block, the distance - determining block resets under the action of the elastic release of the second spring, achieving precise positioning of the side length of the copper block and also clamping both sides of the copper block, further improving the grinding effect.

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] Embodiment 1 As Figures 1 to 8 shown, a copper alloy part welding burr cleaning device according to an embodiment of the present invention includes a support frame 1. A rotating sleeve 12 is rotatably connected to the support frame 1. One end of the rotating sleeve 12 is rotatably provided with a rotating shaft 11. A tray 13 is fixedly connected to the rotating sleeve 12. A displacement box 48 is provided at one end of the support frame 1. A grinding device is provided on the displacement box 48. The grinding device includes a rotating shaft 22. Fixed rods 23 are symmetrically arranged on one side of the rotating shaft 22. A rotating sleeve 24 is rotatably connected to the surface of each fixed rod 23. A sand belt 25 is drivingly connected between the two rotating sleeves 24 and the rotating shaft 22; An adjusting component is provided below the grinding device. The adjusting component includes a one-way rotating component and a distance adjusting component. The one-way rotating component includes an intermittent gear 33. A transmission gear 34 is fixedly connected to the surface of the rotating shaft 11. The intermittent gear 33 meshes with the transmission gear 34. When the intermittent gear 33 rotates clockwise, the rotating sleeve 12 is driven to rotate by the rotation of the rotating shaft 11, so that the copper plate on the tray 13 rotates. When the intermittent gear 33 rotates counterclockwise, the rotating sleeve 12 remains stationary; The grinding device is arranged on the top of the displacement box 48. The distance adjusting component is arranged in the displacement box 48. The distance adjusting component includes a displacement plate 53. The rotating shaft 22 is rotatably arranged on the top of the displacement plate 53. Two sliders 57 are slidably arranged on the top of the displacement box 48. One fixed rod 23 is fixed on the top of one slider 57. By moving the displacement plate 53, the slider 57 slides, so as to change the distance between the rotating shaft 22 and the fixed rod 23, and further adjust the length of the sand belt 25 between the two fixed rods 23.

[0025] Specifically, a suction nozzle is provided on the tray 13 for fixing the copper block; There are still some deficiencies in the prior art during actual use. The burrs at the welding joints of the copper blocks are removed by grinding with the sand belt 25. Since the length and width of the rectangular copper blocks are different, in order to completely grind the burrs at the welding joints, it is necessary to move the grinding device during grinding. However, during the moving process, this device will inevitably vibrate, causing the distance between the fixed rod 23 and the welding joint to fluctuate, resulting in excessive grinding, and thus causing the non-target area near the welding joint of the copper block to be over-ground, damaging the original dimensional accuracy and surface integrity of the copper block.

[0026] Therefore, the present invention solves this problem by setting a corresponding structure. When it is necessary to clean the burrs of the copper block welding, the copper block is first placed on the tray 13 so that one side of the copper block is parallel to the abrasive belt 25, and then the gear rod 44 is rotated counterclockwise so that the abrasive belt 25 abuts against the welding part of the copper block, and the length of the abrasive belt 25 is made greater than the side length of the rectangle abutting against the abrasive belt 25 by the distance adjustment component, so that the burrs of the copper block welding can be polished at one time. After grinding one side, the intermittent gear 33 is rotated clockwise for one circle to rotate the rotating sleeve 12 ninety degrees, thereby rotating the copper plate on the tray 13 so that the other side is in the grinding position. Through the above operation, the welding burrs are ground, and this reciprocating process is repeated to grind the welding burrs of the copper block.

[0027] Embodiment 2 like Figures 2 to 8 As shown, compared with Example 1, another implementation of the present invention is: like Figures 2 to 5 As shown, the one-way rotating component of this embodiment also includes a motor 2 31, the output end of the motor 2 31 is fixedly connected to a guide column 32, an intermittent gear 33 is fixed on the guide column 32, a rotating sleeve 12 is provided with an abutment groove 1 35, a rotating shaft 11 is provided with an abutment groove 2 36, a fixed shaft 37 is fixedly connected to the abutment groove 2 36, a rotating plate 38 is rotatably connected to the surface of the fixed shaft 37, and a spring 1 39 is fixedly connected between the rotating plate 38 and the abutment groove 2 36; the ratio of the number of teeth of the intermittent gear 33 to the number of teeth of the transmission gear 34 is one to four, when the intermittent gear 33 rotates one circle, the transmission gear 34 only rotates ninety degrees, which is used for the steering of the copper block; The adjustment assembly also includes a moving part, which includes a multiplier rod 41, which is located on one side of the motor 2 31, and a belt 1 42 is connected to the multiplier rod 41 and the guide column 32 for transmission. Two racks 46 are fixedly connected to the bottom of the displacement box 48, and two gear rods 44 are rotatably arranged on one side of the rack 46, and one rack 46 is meshed with a gear rod 44. A belt 2 43 is connected to the multiplier rod 41 and a gear rod 44 for transmission, and a belt 3 45 is connected between the two gear rods 44. A guide block 47 is fixedly arranged under the displacement box 48, and the displacement box 48 slides on the guide block 47.

[0028] Specifically, the circumference ratio of the guide column 32 to the multiplier rod 41 is three to one. When the guide column 32 rotates one circle, the multiplier rod 41 rotates three circles. The circumference of the multiplier rod 41 is the same as that of the rotating rod on the gear rod 44. Initially, the intermittent gear 33 is meshed with the transmission gear 34; When grinding is required, the sand belt 25 needs to be attached to the welding joint of the copper block. At this time, start the second motor 31 so that its output end drives the guide post 32 to rotate counterclockwise. Through the intermittent gear 33, the transmission gear 34 drives the first rotating shaft 11 to rotate by 90 degrees. During this process, as the first rotating shaft 11 rotates, one side of the rotating plate 38 abuts against the inner wall of the first abutting groove 35 and rotates with it. The rotating plate 38 rotates around the fixed shaft 37 as the axis, thereby pressing the rotating plate 38 into the second abutting groove 36 and elastically compressing the first spring 39 until it rotates to the next first abutting groove 35 and then resets under the elastic release of the first spring 39. This process is repeated, so that when the first rotating shaft 11 rotates, the first rotating sleeve 12 remains stationary; During the rotation of the guide post 32, when the guide post 32 rotates one circle, the multiplying rod 41 rotates three circles through the transmission of the first belt 42, so that the gear rod 44 rotates counterclockwise three circles; At this time, through the rotation of the guide post 32, one gear rod 44 drives another gear rod 44 to rotate synchronously through the third belt 45 during rotation, so that the two racks 46 drive the displacement box 48 to slide, making the displacement box 48 move more stably, and making the sand belt 25 on it approach the copper block until it is attached to the welding joint of the copper block. At this time, turn off the second motor 31; When the copper block needs to be turned, start the second motor 31 so that its output end drives the guide post 32 to rotate clockwise by one circle. Through the intermittent gear 33, the transmission gear 34 drives the first rotating shaft 11 to rotate by 90 degrees. During this process, as the first rotating shaft 11 rotates, one side of the rotating plate 38 abuts against the inner wall of the first abutting groove 35 and rotates with it. The rotating plate 38 rotates around the fixed shaft 37 as the axis, so that the other side of the rotating plate 38 abuts against the inner wall of the second abutting groove 36 and elastically stretches the first spring 39, thereby keeping the first rotating shaft 11 and the first rotating sleeve 12 relatively fixed, making the first rotating sleeve 12 rotate by 90 degrees, and further making the copper block rotate by 90 degrees so that the other side is in the grinding position; During the clockwise rotation of the guide post 32, through the above operations, the sand belt 25 on the displacement box 48 quickly moves away from the copper block to prevent the problem of collision with the grinding device during the rotation of the copper block due to different sizes of the copper block. Subsequently, through the above steps, the sand belt 25 is attached to the welding joint of the copper block.

[0029] In the present invention, through the clockwise rotation of the guide post 32, 11 is relatively fixed with the first rotating sleeve 12 under the action of the rotating plate 38, so that the copper block rotates by 90 degrees and the other half is in the grinding position to complete its turning. At the same time, through the rotation of the multiplying rod 41, the gear rod 44 drives the rack 46 to move synchronously, so that the sand belt 25 on the displacement box 48 quickly moves away from the copper block to prevent the problem of collision with the grinding device during the rotation of the copper block due to different sizes of the copper block. Through the reverse movement of the guide post 32, when the copper block is stationary, the displacement box 48 moves in the reverse direction, and the sand belt 25 on it is attached to the welding joint of the copper block, realizing the attachment of the sand belt 25 to the welding joint after the copper block is turned.

[0030] like Figure 7 and Figure 8 As shown, in the present embodiment, a distance component is arranged on the top of each fixed rod 23, and the distance component includes a fixed plate 61, a telescopic rod 62 is fixedly connected to one side of the fixed plate 61, a telescopic sleeve 63 is slidably connected to one end of the telescopic rod 62, a spring 2 64 is fixedly connected between the telescopic rod 62 and the telescopic sleeve 63, a distance block 65 is fixedly connected to one end of the telescopic sleeve 63, a contact 1 66 is fixedly connected to one end of the telescopic rod 62, a contact 2 67 is fixedly connected to the inner wall of one end of the telescopic sleeve 63, the contact 1 66 is on the movement trajectory of the contact 2 67, and when the telescopic sleeve 63 slides, the contact 1 66 and the contact 2 67 will abut against each other.

[0031] Specifically, the distance block 65 is hollow inside and has low weight, so it does not affect the sliding of the telescopic sleeve 63; Initially, the second spring 64 is not deformed. When the abrasive belt 25 approaches the welding position of the copper block, the distance block 65 will first contact the surface of the copper block. As the abrasive belt 25 continues to move, the telescopic sleeve 63 slides toward the direction close to the fixed plate 61 and elastically compresses the second spring 64 until the first contact 66 contacts the second contact 67. When the fixing rod 23 moves toward the direction away from the middle of the guide groove 2 56, the distance assembly moves synchronously until the distance block 65 no longer abuts against the surface of the copper block. Under the elastic release of the spring 2 64, the distance block 65 is reset. At this time, the distance block 65 clamps both sides of the copper block.

[0032] like Figures 4 to 7 As shown, the pitch adjustment component of this embodiment also includes a screw rod 51, which rotates in the displacement box 48, and a guide rod 52 is symmetrically fixedly connected in the displacement box 48. A motor 3 54 is fixedly connected to one end of the displacement box 48. A guide groove 1 55 is opened at the top of the displacement box 48, and a guide groove 2 56 is opened at one end of the top of the displacement box 48. Two limit rods 1 58 are fixedly connected to the bottom of the displacement plate 53, and a limit rod 2 59 is fixedly connected to the bottom of each slider 57. A connecting plate 510 is rotatably connected between a limit rod 1 58 and a limit rod 2 59, and a motor 21 is fixedly connected to the top of the displacement plate 53. The displacement plate 53 is threadedly connected to the screw rod 51, and the displacement plate 53 slides on the two guide rods 52, so that the displacement plate 53 can only move in a straight line. The output end of the motor 1 21 is fixed to the rotating shaft 22 , the rotating shaft 22 slides in the guide groove 1 55 , the slider 57 slides in the guide groove 2 56 , and the top of the connecting plate 510 abuts against the bottom of the displacement plate 53 , so that the connecting plate 510 can only move horizontally.

[0033] Specifically, when the first contact 66 abuts against the second contact 67, the third motor 54 is started. The rotation of the lead screw 51 drives the displacement plate 53 to move. Under the action of the connecting plate 510, when the displacement plate 53 moves, the displacement plate 53 drives the second rotating shaft 22 to move towards the direction close to the second guiding groove 56. Under the action of the connecting plate 510, the slider 57 moves away from the lead screw 51, so as to adjust the length of the abrasive belt 25 between the two second rotating sleeves 24, making the length of the abrasive belt 25 greater than the side length of the rectangle it abuts against, facilitating the one-time grinding of the welding burrs of the copper block, and thus improving the grinding effect.

[0034] Working principle: When it is necessary to clean the welding burrs of the copper block, first place the copper block on the tray 13 so that one side of it is parallel to the abrasive belt 25. At this time, start the second motor 31, and its output end drives the guiding column 32 to rotate counterclockwise. Through the intermittent gear 33, the driving gear 34 drives the first rotating shaft 11 to rotate by 90 degrees. During this process, when the first rotating shaft 11 rotates, one side of the rotating plate 38 abuts against the inner wall of the first abutting groove 35 and rotates along with it. The rotating plate 38 rotates around the fixed shaft 37 as the axis, so as to press the rotating plate 38 into the second abutting groove 36 and elastically compress the first spring 39 until it rotates to the next first abutting groove 35, and then resets under the elastic release of the first spring 39. In this way, when the first rotating shaft 11 rotates, the first rotating sleeve 12 remains stationary; During the rotation of the guiding column 32, when the guiding column 32 rotates one circle, the multiplying lever 41 rotates three circles through the transmission of the first belt 42, so that the gear rod 44 rotates counterclockwise three circles; At this time, through the rotation of the guiding column 32, one gear rod 44 drives another gear rod 44 to rotate synchronously when rotating through the third belt 45, so that the two racks 46 drive the displacement box 48 to slide, making the displacement box 48 move more stably, and making the abrasive belt 25 on it approach the copper block until it fits against the welding part of the copper block. At this time, turn off the second motor 31; When the abrasive belt 25 approaches the welding part of the copper block, the fixed-distance block 65 will first abut against the surface of the copper block. As the abrasive belt 25 continues to move, the telescopic sleeve 63 slides towards the direction close to the fixed plate 61 and elastically compresses the second spring 64 until the first contact 66 abuts against the second contact 67; When the first contact 66 abuts against the second contact 67, the third motor 54 is started. The rotation of the lead screw 51 drives the displacement plate 53 to move. Under the action of the connecting plate 510, when the displacement plate 53 moves, the displacement plate 53 drives the second rotating shaft 22 to move towards the direction close to the second guide groove 56. The slider 57 moves away from the lead screw 51 under the action of the connecting plate 510, so as to adjust the length of the abrasive belt 25 between the two second rotating sleeves 24. At the same time, the distance-determining assembly moves synchronously with the fixed rod 23. Until the distance-determining block 65 no longer abuts against the surface of the copper block, the distance-determining block 65 resets under the elastic release of the second spring 64. At this time, the distance-determining block 65 clamps both sides of the copper block. Subsequently, the second motor 31 is continuously started to make its output end rotate counterclockwise until the abrasive belt 25 abuts against the welding part of the copper block. At this time, the second motor 31 is turned off. After one side of the copper block is polished, when the copper block needs to be turned, the second motor 31 is started to make its output end drive the guide post 32 to rotate clockwise for one circle. Through the intermittent gear 33, the transmission gear 34 drives the first rotating shaft 11 to rotate by 90 degrees. During this process, when the first rotating shaft 11 rotates, one side of the rotating plate 38 abuts against the inner wall of the first abutting groove 35 and rotates along with it. The rotating plate 38 rotates around the fixed shaft 37 as the axis, so that the other side of the rotating plate 38 abuts against the inner wall of the second abutting groove 36 and elastically stretches the first spring 39, so as to keep the first rotating shaft 11 and the first rotating sleeve 12 relatively fixed, making the first rotating sleeve 12 rotate by 90 degrees, and then making the copper block rotate by 90 degrees, so that the other side of the copper block is at the polishing position. During the clockwise rotation of the guide post 32, through the above operations, the abrasive belt 25 on the displacement box 48 quickly moves away from the copper block, preventing the problem that the copper block collides with the polishing device during the rotation due to different copper block sizes. Subsequently, through the above steps, the abrasive belt 25 is attached to the welding part of the copper block, and so on, so as to polish the welding burrs of the copper block.
