Description

Technical Field

[0001] This utility model relates to the technical field of pipe processing equipment, and in particular to a device for removing burrs from the ends of stainless steel pipes. Background Technology

[0002] After stainless steel pipes are cut or processed, sharp burrs inevitably form at their ends. These burrs not only affect the quality of subsequent welding or connection but also pose safety hazards. Therefore, removing burrs from the ends of stainless steel pipes is an essential step in pipe fitting processing.

[0003] Existing pipe deburring tools typically require the tool to be inserted into the pipe before use. The operator needs to perform a clamping action, such as by rotating the handle to open certain parts, to secure the tool to the inner wall of the pipe and prevent it from wobbling during deburring.

[0004] After the tool is fixed in place, the operator needs to perform a second separate action: manually adjusting the position of the grinding head to ensure it fits precisely against the end face of the pipe. This step-by-step process is not only cumbersome but also relies entirely on the operator's experience, making it difficult to guarantee quick and accurate positioning each time, thus resulting in low overall processing efficiency.

[0005] Therefore, this utility model proposes a burr removal device for stainless steel pipe ends to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing stainless steel pipe end burr removal devices, such as the need for separate clamping and grinding positioning, poor linkage, and cumbersome operation, this utility model aims to provide a stainless steel pipe end burr removal device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a burr removal device for stainless steel pipe ends, including: a handle, a clamping assembly mounted on the handle, and a grinding assembly mounted on the handle; the clamping assembly includes a plurality of clamping blocks for clamping the pipe wall, and a screw for driving the clamping blocks; the grinding assembly includes a grinding frame for grinding.

[0008] The front end of the handle is fixedly connected to a threaded ring and a ring holder; the screw is threadedly connected to the threaded ring.

[0009] The grinding assembly also includes a ring rotatably connected to the outside of the screw; the grinding assembly also includes a rotating ring rotatably connected to the outside of the ring frame.

[0010] The grinding assembly further includes a telescopic rod, the base end of which is fixedly connected to the rotating ring, and the grinding frame is fixedly connected to the telescopic end of the telescopic rod.

[0011] The grinding assembly also includes a connecting rod, one end of which is rotatably connected to the outside of the ring, and the other end of which is rotatably connected to the telescopic rod.

[0012] Preferably, a handwheel is fixedly connected to one end of the screw to facilitate the operator to rotate the screw; a pressing block is fixedly connected to the other end of the screw to transmit the axial thrust of the screw.

[0013] Preferably, as a specific assembly relationship, the plurality of clamping blocks are movably connected between the ring and the extrusion block, so that the axial movement of the extrusion block can be converted into the radial movement of the clamping blocks.

[0014] Furthermore, the extrusion block has a conical structure. When the inclined surface of the conical structure moves axially under the drive of the screw, it pushes the clamping block to move radially outward, thereby achieving reliable internal support clamping.

[0015] Preferably, the polishing assembly further includes a hand handle, which is rotatably connected to the opposite side of the fixed connection between the telescopic rod and the polishing frame, allowing the operator to rotate the polishing frame via the hand handle.

[0016] Preferably, the polishing assembly further includes sandpaper, which is wrapped around the outside of the polishing frame and serves as an abrasive medium for directly contacting and removing burrs from the nozzle.

[0017] Preferably, in order to achieve linkage, the ring can slide axially on the screw. When the screw rotates and moves axially, the ring moves axially synchronously, thereby driving the connecting rod.

[0018] Preferably, in order to achieve a more stable structure and more uniform force distribution, multiple connecting rods, telescopic rods, and grinding frames are provided.

[0019] As a further preferred embodiment of the above scheme, the plurality of connecting rods are evenly distributed along the circumference of the ring, ensuring a uniform distribution of thrust.

[0020] As a further preferred embodiment of the above scheme, the plurality of telescopic rods are evenly distributed along the circumference of the rotating ring, ensuring the stability of the grinding frame during the extension process.

[0021] This utility model has the following beneficial effects: 1. This utility model, by setting up a linkage mechanism composed of a ring, connecting rod, telescopic rod and rotating ring, links the axial movement of the screw driving the clamping block with the movement of the telescopic rod driving the grinding frame to extend. This solves the problem that clamping and positioning and grinding positioning need to be performed step by step in the prior art, which is cumbersome and inefficient. It achieves the technical effect of simultaneous automatic completion of clamping and positioning, convenient operation and accurate positioning.

[0022] 2. In this utility model, the screw is driven by a handwheel, and the screw drives the extrusion block to open the clamping block outward, forming a stable support inside the tube, which provides a solid foundation for subsequent grinding. The clamping structure is simple and reliable.

[0023] 3. This utility model uses an independent hand lever to drive the grinding frame to rotate, and a rotating ring cooperates with the ring frame to separate the grinding action from the clamping action, making the operation flexible, the grinding uniform, and ensuring the grinding effect on the pipe opening.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example: Please refer to Figures 1 to 4 This utility model provides a burr removal device for stainless steel pipe ends, which aims to solve the problems of the prior art where clamping and positioning and grinding positioning need to be performed in separate steps, have poor linkage, and are cumbersome to operate.

[0028] like Figure 1 As shown, the stainless steel pipe end burr removal device includes a handle 105, a clamping assembly 1 installed on the handle 105, and a grinding assembly 2 installed on the handle 105. The clamping assembly 1 is used to clamp the pipe wall, and the grinding assembly 2 is used to grind the pipe end.

[0029] The specific structure of this embodiment is as follows: a threaded ring 106 and a ring frame 107 are fixedly connected to the front end of the handle 105; the clamping assembly 1 includes a screw 103, which is threadedly connected to the threaded ring 106; the clamping assembly 1 also includes multiple clamping blocks 102 for clamping the pipe wall; the grinding assembly 2 includes a grinding frame 206 for grinding; the core linkage structure of this solution is that the grinding assembly 2 also includes a circular ring 201, which is rotatably connected to the outside of the screw 103; the grinding assembly 2 also includes a rotating ring 207, which is rotatably connected to the outside of the ring frame 107; the grinding assembly 2 also includes a telescopic rod 203, the base end of which is fixedly connected to the rotating ring 207; the grinding frame 206 is fixedly connected to the telescopic end of the telescopic rod 203; the grinding assembly 2 further includes a connecting rod 202, one end of which is rotatably connected to the outside of the circular ring 201, and the other end of which is rotatably connected to the telescopic rod 203.

[0030] For details, please refer to Figure 3 One end of the screw 103 is fixedly connected to a handwheel 104, and the other end of the screw 103 is fixedly connected to a pressing block 101. Multiple clamping blocks 102 are movably connected between the ring 201 and the pressing block 101. The pressing block 101 is preferably a conical structure. When the handwheel 104 is rotated, the screw 103 moves axially inside the threaded ring 106, and the pressing block 101 moves accordingly and pushes the multiple clamping blocks 102 to move radially outward to achieve clamping. The ring 201 can slide axially on the screw 103. During the axial movement of the screw 103, the ring 201 moves synchronously and drives the telescopic rod 203 to extend through the connecting rod 202. Please refer to Figure 1 The polishing assembly 2 also includes a hand handle 204, which is rotatably connected to the opposite side of the fixed connection between the telescopic rod 203 and the polishing frame 206. The polishing assembly 2 also includes sandpaper 205, which is wrapped around the outside of the polishing frame 206. To ensure structural stability and uniform stress distribution, multiple connecting rods 202, telescopic rods 203, and grinding frames 206 are provided. Multiple connecting rods 202 are evenly distributed along the circumference of the ring 201, and multiple telescopic rods 203 are evenly distributed along the circumference of the rotating ring 207.

[0031] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 3 A handwheel 104 is fixedly connected to one end of the screw 103, and an extrusion block 101 is fixedly connected to the other end of the screw 103.

[0032] In a preferred embodiment, a plurality of clamping blocks 102 are movably connected between the ring 201 and the extrusion block 101.

[0033] In a preferred embodiment, the extrusion block 101 has a conical structure, which pushes a plurality of clamping blocks 102 to move radially outward when the extrusion block 101 moves axially.

[0034] In a preferred embodiment, the polishing assembly 2 also includes a hand handle 204, which is rotatably connected to the opposite side of the fixed connection between the telescopic rod 203 and the polishing frame 206.

[0035] In a preferred embodiment, the polishing assembly 2 also includes sandpaper 205, which is wrapped around the outside of the polishing frame 206.

[0036] In a preferred embodiment, the ring 201 can slide axially on the screw 103.

[0037] In one preferred embodiment, multiple connecting rods 202, telescopic rods 203, and grinding frames 206 are provided.

[0038] As a preferred embodiment, and following the above scheme, multiple connecting rods 202 are evenly distributed along the circumference of the ring 201.

[0039] As a preferred embodiment, and following the above scheme, multiple telescopic rods 203 are evenly distributed along the circumference of the rotating ring 207.

[0040] The working principle of this stainless steel pipe end burr removal device is as follows: When deburring the ends of a stainless steel pipe is required, the device is inserted into the pipe by holding the handle 105. Turning the handwheel 104 causes the screw 103 to rotate within the threaded ring 106, resulting in axial movement. The pressing block 101, fixedly connected to the other end of the screw 103, moves axially accordingly. Because the pressing block 101 has a conical structure, its movement pushes multiple clamping blocks 102, movably connected between it and the ring 201, to move radially outward until the clamping blocks 102 press against the inner wall of the stainless steel pipe, thus firmly clamping and fixing the entire device.

[0041] Simultaneously with the aforementioned clamping action, the linkage mechanism begins to operate. The ring 201, rotatably connected to the outside of the screw 103, is also driven to move axially in sync with the axial movement of the screw 103. The ring 201, through the connecting rod 202 rotatably connected to its outside, exerts a force on the telescopic rod 203. Since the base end of the telescopic rod 203 is fixedly connected to the rotating ring 207, this force causes the telescopic rod 203 to stretch. The grinding frame 206, fixedly connected to the telescopic end of the telescopic rod 203, is then pushed out until the sandpaper 205 wrapped around the outside of the grinding frame 206 is precisely positioned and adheres to the end face of the stainless steel tube.

[0042] After automatic clamping and positioning are completed, the operator holds the hand lever 204 and rotates it. Since the hand lever 204 is rotatably connected to the connection between the telescopic rod 203 and the grinding frame 206, the rotation of the hand lever 204 will drive the grinding frame 206 to rotate at high speed. Simultaneously, the rotating ring 207 is rotatably connected to the outside of the ring frame 107, allowing the grinding structure composed of the grinding frame 206, telescopic rod 203, etc., to rotate around the device's axis. The rotating sandpaper 205 grinds the nozzle opening, thereby efficiently removing burrs.

[0043] By linking the axial movement of the screw 103 with the stretching action of the telescopic rod 203, this utility model achieves the synchronous and automatic completion of the two actions of clamping the pipe wall and positioning the grinding frame 206, solving the problems of step-by-step operation, cumbersome positioning and low efficiency in the prior art.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
