Description

Technical Field

[0001] This utility model relates to the field of chamfering device technology, and in particular to a chamfering device for a brake tube. Background Technology

[0002] The brake pipe needs to be chamfered during processing. During the chamfering process, a clamping device is needed to hold and fix the brake pipe. However, because the brake pipe is hollow inside, it is easy for the brake pipe to deform during the clamping process, which affects the product quality.

[0003] Existing technology CN218224951U discloses a chamfering device for brake pipes, including a chamfering machine. A fixing plate is bolted to the clamp mounting point of the chamfering machine. A fixing pipe is positioned above the fixing plate. Several support rings are fixedly sleeved on the outer periphery of the fixing pipe. The support rings are fixedly connected to the fixing plate by several support rods. A pipe positioning assembly is provided inside the fixing pipe, and the pipe positioning assembly is connected to the fixing pipe by a support assembly. By simultaneously pressing the brake pipe wall from both the inside and outside through the support assembly and the pipe positioning assembly, the position of the brake pipe is clamped and fixed, preventing excessive pressure between the clamp and the brake pipe from causing deformation. This avoids subsequent processing and correction of the brake pipe, and improves the production rate of brake pipe chamfering.

[0004] The aforementioned device uses the expansion of the air bladder to drive the first and second sliders to move, thereby clamping the inner and outer walls of the brake tube. However, air is easily compressed, and the brake tube is prone to shifting during clamping, affecting the chamfering. Utility Model Content

[0005] The purpose of this utility model is to provide a chamfering device for a brake tube, which solves the problem that the existing chamfering device for a brake tube uses the expansion of an air bladder to drive the movement of the first and second sliders to clamp the inner and outer walls of the brake tube. However, the air is easily compressed, and the brake tube is prone to displacement and shaking during the clamping process.

[0006] To achieve the above objectives, this utility model provides a chamfering device for a brake pipe, including a worktable and a chamfering assembly. The chamfering assembly is disposed on one side of the worktable, and a fixing assembly is also included. The fixing assembly includes a housing, a slider, an inner clamping plate, a moving component, an outer clamping plate, and a rotating component. The housing is fixedly connected to the worktable and located on one side of the worktable. The slider is slidably connected to the housing and disposed on the housing. The inner clamping plate is fixedly connected to the slider and located on one side of the slider. The moving component is disposed inside the housing. The outer clamping plate is slidably connected to the housing and disposed on the housing. The rotating component is disposed on the housing.

[0007] The fixing assembly further includes a first guide rod and a second guide rod. The first guide rod is fixedly connected to the housing and to the slider, and passes through the slider. The second guide rod is fixedly connected to the housing and slidably connected to the outer clamping plate.

[0008] The movable component includes a threaded rod, a movable plate, and a connecting rod. The threaded rod is rotatably connected to the housing and is located inside the housing. The movable plate is threadedly connected to the threaded rod and is sleeved on the threaded rod. The two ends of the connecting rod are rotatably connected to the movable plate and the slider, respectively.

[0009] The rotating component includes a drive disk, a worm gear, and a worm wheel. The drive disk is rotatably connected to the housing and slidably connected to the outer clamping plate, and is located inside the housing. The worm wheel is fixedly connected to the drive disk and is located on one side of the drive disk. The worm gear is rotatably connected to the housing and meshes with the worm wheel.

[0010] The drive disk has a drive groove, which is located on the side of the drive disk near the outer clamping plate, and the drive groove cooperates with the outer clamping plate.

[0011] This utility model discloses a chamfering device for a brake pipe. In use, the brake pipe to be processed is fitted onto multiple inner clamping plates. The moving component is then activated to open the inner clamping plates, allowing them to abut against the inner wall of the brake pipe. Next, the rotating component is activated to move multiple outer clamping plates, allowing them to contact the outer wall of the brake pipe. The inner and outer clamping plates apply clamping force from both the inside and outside of the brake pipe. Because the outer and inner clamping plates are positioned in a one-to-one correspondence, the pressure is evenly distributed across the brake pipe wall, effectively preventing deformation caused by uneven local force and ensuring the brake pipe maintains a stable position and shape during processing. Once the brake pipe is securely clamped, the operator can activate the chamfering assembly to chamfer the brake pipe opening. The multiple inner and outer clamping plates clamp the brake pipe, preventing deformation and improving the stability of the brake pipe fixation. Attached Figure Description

[0021] This utility model provides a chamfering device for a brake pipe, including a worktable 101, a chamfering assembly 102, and a fixing assembly 103.

It can be understood that the above solution can be used to improve the stability of clamping the brake tube.

[0022] In this specific embodiment, the chamfering component 102 is disposed on one side of the workbench 101. The chamfering component 102 adopts a chamfering device in the prior art. The chamfering component 102 is used to chamfer the brake pipe. The chamfering component 102 is the prior art, and its structure and working principle will not be described in detail here.

[0023] The housing 104 is fixedly connected to the worktable 101 and located on one side of the worktable 101. The slider 105 is slidably connected to the housing 104 and disposed on the housing 104. The inner clamping plate 106 is fixedly connected to the slider 105 and located on one side of the slider 105. The moving member 107 is disposed inside the housing 104. The outer clamping plate 108 is slidably connected to the housing 104 and disposed on the housing 104. The rotating member 109 is disposed on the housing 104. Multiple sliders 105, multiple inner clamping plates 106, and multiple outer clamping plates 108 are provided. The moving member 107 is used to drive multiple sliders 105 to move. The rotating member 109 is used to drive multiple outer clamping plates 108 to move. The positions of the outer clamping plates 108 and the inner clamping plates 106 correspond one-to-one.

[0024] In use, the brake tube to be processed is fitted onto the multiple inner clamping plates 106. Then, the moving component 107 is activated to drive the multiple sliders 105 to move, thereby causing the multiple inner clamping plates 106 to open, allowing them to abut against the inner wall of the brake tube. Next, the rotating component 109 is activated to drive the multiple outer clamping plates 108 to move, allowing them to contact the outer wall of the brake tube. The inner clamping plates 106 and the outer clamping plates 108 apply clamping force from both the inside and outside of the brake tube. The outer clamping plate 108 and the inner clamping plate 106 are positioned one-to-one, which can evenly distribute the pressure on the brake pipe wall, effectively avoiding the problem of brake pipe deformation caused by uneven local force, and ensuring that the brake pipe maintains a stable position and shape during processing. After the brake pipe is firmly clamped, the operator can start the chamfering assembly 102 to perform chamfering operation on the brake pipe opening. The brake pipe is clamped by multiple inner clamping plates 106 and multiple outer clamping plates 108, which not only prevents the brake pipe from deforming, but also improves the stability of fixing the brake pipe.

[0025] Secondly, the first guide rod 110 is fixedly connected to the housing 104 and the slider 105, and passes through the slider 105; the second guide rod 111 is fixedly connected to the housing 104 and slidably connected to the outer clamping plate 108; the first guide rod 110 guides the movement of the slider 105, thereby guiding the movement of the inner clamping plate 106 and improving the stability of the inner clamping plate 106 during movement; the second guide rod 111 guides the movement of the outer clamping plate 108, improving the stability of the outer clamping plate 108 during movement.

[0026] Meanwhile, the threaded rod 112 is rotatably connected to the housing 104 and located inside the housing 104; the movable plate 113 is threadedly connected to the threaded rod 112 and sleeved on the threaded rod 112; both ends of the connecting rod 114 are rotatably connected to the movable plate 113 and the slider 105 respectively; multiple connecting rods 114 are provided and are respectively connected to multiple sliders 105; a first rotary motor 119 is also installed on one side of the housing 104, and the output end of the first rotary motor 119 passes through the housing 104 and is connected to the threaded rod 112. The operation of the first rotary motor 119 drives the threaded rod 112 to rotate, causing the threaded rod 112 to drive the movable plate 113 to move, the movable plate 113 to drive the connecting rod 114 to move, and the connecting rod 114 to drive the slider 105 to move, thereby causing the slider 105 to drive the inner clamping plate 106 to move.

[0027] In addition, the drive disk 115 is rotatably connected to the housing 104 and slidably connected to the outer clamping plate 108, and is located inside the housing 104; the worm gear 117 is fixedly connected to the drive disk 115 and is located on one side of the drive disk 115; the worm 116 is rotatably connected to the housing 104 and meshes with the worm gear 117; a second rotary motor 120 is also installed on the housing 104, and the output end of the second rotary motor 120 passes through the housing 104 and is connected to the worm 116.

[0028] Finally, the drive groove 118 is disposed on the side of the drive disk 115 near the outer clamping plate 108, and the drive groove 118 cooperates with the outer clamping plate 108.

[0029] Multiple drive grooves 118 are provided, and the end of the outer clamping plate 108 extends into the drive groove 118. The drive groove 118 is inclined. The second rotary motor 120 drives the worm gear 116 to rotate, which in turn drives the worm wheel 117 to rotate. The worm wheel 117 drives the drive disk 115 to rotate, thereby causing the drive groove 118 on the drive disk 115 to perform circumferential motion. This allows the outer clamping plate 108 to move along the second guide rod 111 under the action of the drive groove 118, thus achieving the purpose of driving the outer clamping plate 108 to move.

[0030] When using the chamfering device for the brake tube of this utility model, the brake tube to be processed is fitted onto multiple inner clamping plates 106. The first rotary motor 119 is started to drive the threaded rod 112 to rotate. The threaded rod 112 drives the moving plate 113 to move. The moving plate 113 drives the connecting rod 114 to move. The connecting rod 114 drives the slider 105 to move. The slider 105 drives the inner clamping plates 106 to move, so that the multiple inner clamping plates 106 can contact the inner wall of the brake tube. Then the second rotary motor 119 is started. The rotary motor 120 drives the worm gear 116 to rotate, which in turn drives the worm wheel 117 to rotate. The worm wheel 117 then drives the drive disk 115 to rotate, causing the drive groove 118 on the drive disk 115 to rotate. This rotation drives the outer clamping plate 108 to contact the outer wall of the brake tube. The inner clamping plate 106 and the outer clamping plate 108 exert force simultaneously from both the inner and outer sides of the brake tube, forming a uniform and stable clamping force. This achieves the purpose of stably clamping the brake tube and prevents it from shifting during processing.
