Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a device for removing burrs from the ends of pipe fittings. Background Technology

[0002] In existing technologies, pipe fittings are typically placed and fixed on a clamp manually. Then, a linear drive module moves a grinding device closer to the end of the pipe fitting, and the grinding head of the grinding device is used to remove burrs from the end face of the pipe fitting. However, there are drawbacks in existing technologies, namely, the clamping force of the clamp on the pipe fitting is too large. When the extension length of the pipe fitting is not appropriate, the grinding head can easily cause over-grinding of the end face of the pipe fitting, resulting in a shortening of the pipe fitting length. If the clamp is unlocked to adjust the extension length of the pipe fitting, it will increase the time cost. At the same time, the manual alignment adjustment method is not precise enough and urgently needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a device for removing burrs from the ends of pipe fittings, which can improve the processing efficiency of pipe fitting end faces, enhance the processing accuracy of pipe fittings, and save labor costs.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pipe fitting end burr removal device, including a clamping mechanism and a positioning and leveling mechanism, wherein the clamping mechanism includes a pre-clamping module and a clamping module, the pre-clamping module is used to clamp the pipe fitting and allow the pipe fitting to slide along the axial direction, and the clamping module is used to clamp and fix the pipe fitting clamped by the pre-clamping module.

[0005] The positioning and leveling mechanism includes a multi-axis drive module, a length positioning module and a deburring module located at the output end of the multi-axis drive module. The multi-axis drive module is used to drive the length positioning module and the deburring module to move closer to or away from the clamping mechanism. The length positioning module includes a linear drive unit and a push rod located at the output end of the linear drive unit. The linear drive unit drives the push rod to engage with the pipe to adjust the extension length of the pipe relative to the pre-clamping module. The deburring module includes a rotary drive unit and an end face leveling cutter head located at the output end of the rotary drive unit.

[0006] By adopting the above technical solution, the pipe is first clamped by the pre-clamping module before grinding. Then, the multi-axis drive module drives the length positioning module to approach the end of the pipe. When the push rod is aligned with the pipe, the linear drive extends the push rod and pushes the pipe to move axially. The push rod extends a preset length and drives the pipe to retract the same stroke relative to the pre-clamping module, so that the extension length of the pipe relative to the pre-clamping module is kept uniform. Then, the clamping module clamps and fixes the pipe to prevent the pipe from moving relative to the clamping mechanism. At the same time, the clamping module releases the clamping of the pipe to avoid interference between the deburring module and the clamping module during operation. Afterward, the multi-axis drive module drives the deburring module to approach the pipe, and the rotary drive unit drives the end face flattening cutter to cut and flatten the end face of the pipe, while removing the burrs on the end face of the pipe. This utility model, through the cooperation of the positioning and flattening mechanism and the clamping mechanism, unifies the extension length of the pipe and reduces labor costs. This utility model has the effects of improving the processing efficiency of the pipe end face, improving the processing accuracy of the pipe, and saving labor costs.

[0007] A further feature of this invention is that the multi-axis drive module includes an X-axis translation structure and a Y-axis translation structure located at the output end of the X-axis translation structure. The output end of the Y-axis translation structure is provided with a mounting bracket, and the linear drive unit and the rotary drive unit are mounted on the mounting bracket.

[0008] By adopting the above technical solution, the linear drive unit and the rotary drive unit can move at any position on the horizontal plane with the cooperation of the X-axis translation structure and the Y-axis translation structure.

[0009] A further feature of this invention is that the mounting bracket is provided with a plurality of linear bearings, and the push rod slides through the linear bearings.

[0010] By adopting the above technical solutions, linear bearings can improve the consistency and smoothness of the push rod's translation direction.

[0011] A further feature of this invention is that a protective cover is fixed on the mounting bracket, and a receiving cavity is formed between the protective cover and the mounting bracket, wherein the linear drive unit and the rotary drive unit are built into the receiving cavity.

[0012] By adopting the above technical solution, the protective cover can prevent external dust and impurities from adhering to the linear drive unit and the rotary drive unit, thus avoiding a reduction in the heat dissipation performance of the linear drive unit and the rotary drive unit.

[0013] A further feature of this invention is that it also includes a purging mechanism, which includes a purging device and a purging nozzle connected to the purging device via a connecting pipe. The purging nozzle is mounted on the protective cover, and the purging port of the purging nozzle faces the flat end face of the blade.

[0014] By adopting the above technical solution, when the end face flattening cutter head grinds the end face of the pipe fitting, the blowing nozzle can continuously blow the processing position of the end face of the pipe fitting, thereby reducing the temperature of the end face flattening cutter head and preventing the end face flattening cutter head from reducing its cutting performance due to high temperature.

[0015] A further feature of this invention is that a hand valve is provided on the connecting pipe of the blowing nozzle.

[0016] By adopting the above technical solution, the operator can use the manual valve to quickly close or open the purge nozzle.

[0017] A further feature of this invention is that the pre-clamping module includes a first driving structure, a first gripper, and a second gripper, wherein the first driving structure drives the first gripper and the second gripper to clamp the pipe and allow the pipe to slide axially.

[0018] By adopting the above technical solution, the first driving structure can drive the first gripper and the second gripper to clamp or move away from each other, thereby clamping or releasing the pipe. At the same time, when the first gripper and the second gripper clamp each other, the pipe can move axially relative to the pre-clamping module, so as to cooperate with the push rod of the length positioning module to push the pipe to move.

[0019] A further configuration of this utility model is: the clamping module includes a fixed clamping component, a movable clamping component, and a second driving structure, wherein the second driving structure drives the movable clamping component to approach the fixed clamping component and clamp the pipe, or the second driving structure drives the movable clamping component to move away from the fixed clamping component and release the pipe.

[0020] A further feature of this invention is that the clamping mechanism is mounted on the support body, the support body is inclined below the pre-clamping module and has a material dropping plate, and the clamping mechanism is provided with a receiving frame below it.

[0021] By adopting the above technical solution, the blanking plate can slide the debris generated during the grinding of pipe fittings into the receiving frame for collection.

[0022] A further feature of this invention is that a push block is installed at the end of the push rod, and the end face of the push block facing the pipe is a plane.

[0023] By adopting the above technical solution, the push rod does not need to be completely aligned with the axial direction of the pipe fitting, and the push rod can still push the pipe fitting to move through the push block.

[0024] In summary, this utility model has the following beneficial effects:

[0025] The system employs a combination of a clamping mechanism and a positioning and leveling mechanism. The clamping mechanism includes a pre-clamping module and a clamping module. The positioning and leveling mechanism includes a multi-axis drive module, a length positioning module located at the output end of the multi-axis drive module, and a deburring module. The multi-axis drive module drives the length positioning module and the deburring module to move closer to or away from the clamping mechanism. The length positioning module includes a linear drive unit and a push rod located at the output end of the linear drive unit. The deburring module includes a rotary drive unit and an end-face leveling cutter located at the output end of the rotary drive unit. Before grinding, the pre-clamping module clamps the pipe. Then, the multi-axis drive module drives the length positioning module to move closer to the end of the pipe. When the push rod is aligned with the pipe, the linear drive extends the push rod and pushes the pipe to move axially. The push rod extends for a preset length. The system moves the pipe fitting back the same distance from the pre-clamping module, ensuring a uniform extension length. The clamping module then secures the pipe fitting, preventing movement relative to the clamping mechanism. Simultaneously, the clamping module releases its grip on the pipe fitting, avoiding interference between the deburring module and the clamping module during operation. The multi-axis drive module then moves the deburring module closer to the pipe fitting, while the rotary drive unit drives the end-face flattening cutter to cut and flatten the end face of the pipe fitting, removing burrs. This invention, through the cooperation of the positioning and flattening mechanism and the clamping mechanism, unifies the extension length of the pipe fitting and reduces labor costs. Therefore, this invention improves the efficiency of pipe fitting end-face processing, enhances processing accuracy, and saves labor costs. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] A device for removing burrs from the ends of pipe fittings, such as Figure 1-3 As shown, the device includes a clamping mechanism 1 and a positioning and leveling mechanism 5. The clamping mechanism 1 includes a pre-clamping module 2 and a clamping module 3. The pre-clamping module 2 is used to clamp the pipe fitting 10 and allow the pipe fitting 10 to slide axially. The clamping module 3 is used to clamp and fix the pipe fitting 10 clamped by the pre-clamping module 2. The positioning and leveling mechanism 5 includes a multi-axis drive module 6, a length positioning module 7 located at the output end of the multi-axis drive module 6, and a deburring module 8. The multi-axis drive module 6 is used to drive the length positioning module 7 and the deburring module 8 to move closer to or away from the clamping mechanism 1. The length positioning module 7 includes a linear drive unit 71 and a push rod 72 located at the output end of the linear drive unit 71. The linear drive unit 71 drives the push rod 72 to engage with the pipe 10 to adjust the extension length of the pipe 10 relative to the pre-clamping module 2. The deburring module 8 includes a rotary drive unit 81 and an end face flattening cutter head 82 located at the output end of the rotary drive unit 81. In this embodiment, the clamping mechanism 1 is used to clamp the pipe 10 and align the pipe 10 along the Y-axis direction. The axial direction of the push rod 72 is parallel to the Y-axis direction.

[0033] like Figure 2-4As shown, the multi-axis drive module 6 includes an X-axis translation structure 61 and a Y-axis translation structure 62 located at the output end of the X-axis translation structure 61. A mounting bracket 621 is provided at the output end of the Y-axis translation structure 62. A linear drive unit 71 and a rotary drive unit 81 are mounted on the mounting bracket 621, allowing the linear drive unit 71 and the rotary drive unit 81 to move at any position on the horizontal plane with the cooperation of the X-axis translation structure 61 and the Y-axis translation structure 62. The mounting bracket 621 is provided with several linear bearings 611, and the push rod 72 slides through the linear bearings 611. The linear bearings 611 improve the consistency and smoothness of the translation direction of the push rod 72. A protective cover 612 is fixed on the mounting bracket 621, forming a receiving cavity 6121 between the protective cover 612 and the mounting bracket 621. The linear drive unit 71 and the rotary drive unit 81 are housed within the receiving cavity 6121, providing protection against damage. The protective cover 612 can prevent external dust and impurities from adhering to the linear drive unit 71 and the rotary drive unit 81, thus reducing the heat dissipation performance of the linear drive unit 71 and the rotary drive unit 81. It also includes a blowing mechanism 4, which includes a blowing device and a blowing nozzle 41 connected to the blowing device through a connecting pipe 42. The blowing nozzle 41 is installed on the protective cover 612, and the blowing port of the blowing nozzle 41 faces the end face flattening cutter head 82. When the end face flattening cutter head 82 grinds the end face of the pipe fitting 10, the blowing nozzle 41 can continuously blow the processing position of the end face of the pipe fitting 10, thereby reducing the temperature of the end face flattening cutter head 82 and preventing the end face flattening cutter head 82 from reducing its cutting performance due to high temperature. A hand valve 421 is provided on the connecting pipe 42 of the blowing nozzle 41, which the operator can use to quickly close or open the blowing nozzle 41.

[0034] like Figure 1 and Figures 3-4As shown, the pre-clamping module 2 includes a first drive structure 21, a first gripper 22, and a second gripper 23. The first drive structure 21 drives the first gripper 22 and the second gripper 23 to clamp the pipe 10 and allow the pipe 10 to slide axially. The first drive structure 21 can drive the first gripper 22 and the second gripper 23 to clamp or move away from each other, thereby clamping or releasing the pipe 10. At the same time, when the first gripper 22 and the second gripper 23 clamp each other, the pipe 10 can move axially relative to the pre-clamping module 2 to cooperate with the push rod 72 of the length positioning module 7 to push the pipe 10 to move. The clamping module 3 includes a fixed clamping assembly 31, a movable clamping assembly 32, and a second drive structure 33. The second drive structure 33... The movable clamping assembly 32 is driven to approach the fixed clamping assembly 31 and clamp the pipe 10, or the second driving structure 33 drives the movable clamping assembly 32 away from the fixed clamping assembly 31 and releases the pipe 10; the clamping mechanism 1 is set on the support body 9, and the support body 9 is inclinedly provided with a dropping plate 91 below the pre-clamping module 2. A receiving frame 92 is provided below the clamping mechanism 1. The dropping plate 91 can slide the debris generated when the pipe 10 is polished into the receiving frame 92 for collection; a push block 721 is installed at the end of the push rod 72. The end face of the push block 721 facing the pipe 10 is set as a plane, so that the push rod 72 does not need to be completely aligned with the axial direction of the pipe 10, and the push rod 72 can also push the pipe 10 to move through the push block 721.

[0035] The basic working principle of this utility model is as follows: By simultaneously setting a clamping mechanism 1 and a positioning and leveling mechanism 5, the clamping mechanism 1 includes a pre-clamping module 2 and a clamping module 3. The positioning and leveling mechanism 5 includes a multi-axis drive module 6, a length positioning module 7 located at the output end of the multi-axis drive module 6, and a deburring module 8. The multi-axis drive module 6 is used to drive the length positioning module 7 and the deburring module 8 to move closer to or away from the clamping mechanism 1. The length positioning module 7 includes a linear drive unit 71 and a push rod 72 located at the output end of the linear drive unit 71. The deburring module 8 includes a rotary drive unit 81 and an end face leveling cutter head 82 located at the output end of the rotary drive unit 81. Before grinding, the pre-clamping module 2 clamps the pipe 10. Then, the multi-axis drive module 6 drives the length positioning module 7 to move closer to the end of the pipe 10. When the push rod 72 is aligned with the pipe 10, the linear drive push rod 72 extends and pushes the pipe 10 axially. The push rod 72 extends to a preset length and drives the pipe 10 to retract by the same stroke relative to the pre-clamping module 2, thereby keeping the extension length of the pipe 10 relative to the pre-clamping module 2 uniform. Then, the clamping module 3 clamps and fixes the pipe 10 to prevent the pipe 10 from moving relative to the clamping mechanism 1. At the same time, the clamping module 2 releases its clamping of the pipe 10 to avoid interference between the deburring module 8 and the clamping module 2 during operation. Afterward, the multi-axis drive module 6 drives the deburring module 8 to approach the pipe 10, and the rotation drive unit 81 drives the end face flattening cutter head 82 to cut and flatten the end face of the pipe 10, while removing the burrs on the end face of the pipe 10. This utility model, through the cooperation of the positioning and flattening mechanism 5 and the clamping mechanism 1, unifies the extension length of the pipe 10 and reduces labor costs. This utility model has the effects of improving the processing efficiency of the pipe end face, improving the processing accuracy of the pipe, and saving labor costs.
