Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a tooling for grinding the ends of pipes. Background Technology

[0002] As one of the most commonly used components in mechanical equipment, steel pipes require different adaptive processing depending on the specific application. For example, to facilitate assembly, avoid burr scratches, and ensure a good seal, both the inner and outer sides of the steel pipe are chamfered. In existing technology, the steel pipe is usually placed in a clamping fixture, and then the two ends of the steel pipe are chamfered using grinding equipment. Since both the inner and outer sides of the steel pipe need to be chamfered, and the position of the steel pipe is fixed, the chamfering operation is usually completed in two processes. This prolongs the production sequence and affects production efficiency. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a tooling for grinding pipe ends, which can simultaneously complete the chamfering of the inner and outer sides of the pipe in one tooling, shorten the time sequence, improve production efficiency, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology: A tooling for grinding the end of a pipe includes: a base, a clamping assembly, and a limiting assembly.

[0005] The base has a through groove running vertically through its top surface. The clamping assembly includes two support rings positioned above the through groove and rotating around their own axes. The axis of the support rings is parallel to the length of the base, and multiple equally spaced clamping blocks are arranged on their outer sides along their circumference. The clamping blocks are V-shaped and move synchronously along the radial direction of the support rings to clamp the pipe. The limiting assembly includes two first limiting plates, respectively positioned on the outer sides of the support rings and arranged coaxially. The first limiting plates are arc-shaped, and the angle between their two ends and the center of the circle is greater than 180 degrees. An arc-shaped second limiting plate is provided between the two ends of the first limiting plate. A notch is formed between the two ends of the second limiting plate and the two ends of the first limiting plate. One of the notches is located in the through groove for the pipe to pass through. In application, the inner walls of the first and second limiting plates contact the side walls of the pipe.

[0006] Furthermore, the support ring is mounted on the rotating shaft, which is rotatably mounted on the side plate, and one end of the shaft is connected to the output end of the rotating motor. The rotating motor is mounted on the side plate, and the side plate is mounted on the base.

[0007] Furthermore, a sliding rod is provided at the bottom of the clamping block. The sliding rod passes through the support ring and is rotatably connected to one end of the connecting rod. The other end of the connecting rod is rotatably connected to the rotating ring, and the rotating ring is rotatably mounted on the support ring.

[0008] Furthermore, the rotating ring has multiple threaded holes spaced apart along its circumference on its side, and screws are inserted into the threaded holes. The screws are threadedly connected to the support ring to lock the rotating ring.

[0009] Furthermore, a bracket is provided on the outer side of the first limiting plate, and a telescopic rod is installed on the bracket. The moving end of the telescopic rod is connected to a horizontal plate, and pressure blocks are provided at both ends of the horizontal plate. The pressure blocks are V-shaped and, in application, cooperate with the clamping blocks to clamp the pipe.

[0010] Furthermore, a connecting plate is provided on the outer side of the first limiting plate. The connecting plate is sleeved on the arc-shaped rod, and arc-shaped baffles are provided at both ends. The arc-shaped rod is installed on the first limiting plate, and the baffles are coaxial and of the same diameter as the first limiting plate, which are used to seal the gap at a higher position.

[0011] The advantages of this utility model are as follows: the clamping component can clamp multiple pipes at the same time, which facilitates the simultaneous chamfering of the inner and outer sides of the pipes, shortens the time sequence, and improves production efficiency; both the clamping block and the pressure block adopt a V-shaped structure, and the clamping block is movable. The pipes are limited by the limiting plate, which can also adapt to pipes of different sizes, enhance versatility, and reduce tooling costs. Attached Figure Description

[0016] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figures 1-3 As shown, this example provides a tooling for grinding pipe ends, including: a base 100, a clamping assembly 200, and a limiting assembly 300.

[0018] The base 100 has a through groove 101 extending vertically on its top surface. The clamping assembly 200 includes two support rings 201 positioned above the through groove 101 and rotating around their own axes. The axes of the support rings 201 are parallel to the length of the base 100, and multiple equally spaced clamping blocks 202 are arranged on their outer sides along their circumference. The clamping blocks 202 are V-shaped and move synchronously along the radial direction of the support rings 201 to clamp the pipe. The limiting assembly 300 includes two first limiting plates 301 respectively positioned on the outer sides of the support rings 201 and arranged coaxially. The first limiting plates 301 are arc-shaped, and the angle between their two ends and the center is greater than 180 degrees. An arc-shaped second limiting plate 302 is provided between the two ends of the first limiting plate 301. A notch is formed between the two ends of the second limiting plate 302 and the two ends of the first limiting plate 301. One notch is located in the through groove 101, and the other notch... Located on one side of the base 100 along its length, the clamping block 202 is used to pass through the pipe. When the clamping block 202 holds the pipe, the inner walls of the first limiting plate 301 and the second limiting plate 302 contact the side wall of the pipe. During processing, the pipe is placed into the clamping block 202 from the higher notch. Then, the support ring 201 is rotated, and the pipe is manually limited until the outer wall of the pipe contacts the inner wall of the first limiting plate 301 to prevent the pipe from slipping. After the support ring 201 has rotated to a predetermined angle, the two grinding heads of the grinding equipment grind the ends of the two pipes simultaneously. The outer wall of one pipe is ground, and the inner wall of the other pipe is ground. After grinding, the pipe can fall into the through groove 101 from the lower notch and be collected. Thus, the grinding of the inner and outer walls of the pipe is completed in one tooling, shortening the production time and improving production efficiency.

[0019] Specifically, the support ring 201 is mounted on the rotating shaft 203, which is rotatably mounted on the side plate 102, and one end of the shaft is connected to the output end of the rotating motor. The rotating motor is mounted on the side plate 102, which is mounted on the base 100. By driving the rotating shaft 203 to rotate through the rotating motor, the support ring 201 can be rotated, causing the pipe to make a circular motion.

[0020] Specifically, the bottom end of the clamping block 202 is provided with a sliding rod 204, which passes through the support ring 201 and is rotatably connected to one end of the connecting rod 205. The other end of the connecting rod 205 is rotatably connected to the rotating ring 206, which is rotatably mounted on the support ring 201. When it is necessary to perform end grinding operations on pipes of different diameters, the rotating ring 206 is rotated. Under the pull of the connecting rod 205, the sliding rod 204 will move radially along the support ring 201, thereby adjusting the distance between the clamping block 202 and the first limiting plate 301 to ensure that when the pipe is placed in the clamping block 202, the pipe can contact the inner wall of the first limiting plate 301 and prevent the pipe from falling off.

[0021] Specifically, the rotating ring 206 has a plurality of threaded holes 207 arranged at intervals along its circumference on its side. Screws are inserted into the threaded holes 207 and are threaded to the support ring 201 to lock the rotating ring 206. When it is necessary to rotate the rotating ring 206, the screws are removed from the threaded holes 207 to release the fixation of the rotating ring 206. Then the rotating ring 206 is rotated by a predetermined angle, and then the screws are inserted into the threaded holes 207.

[0022] Specifically, to prevent the pipe from rotating with the grinding head due to friction during the grinding process, a bracket 303 is provided on the outside of the first limiting plate 301. A telescopic rod 304 is installed on the bracket 303. The moving end of the telescopic rod 304 is connected to a horizontal plate 305. Pressure blocks 306 are provided at both ends of the horizontal plate 305. The pressure blocks 306 are V-shaped. When the pipe end needs to be ground, the telescopic rod 304 drives the horizontal plate 305 to move toward the central axis of the support ring 201. The pressure blocks 306 cooperate with the clamping block 202 to clamp the pipe, thereby preventing the pipe from rotating.

[0023] Specifically, to facilitate the placement of the pipe on the clamping block 202, a connecting plate 307 is provided on the outside of the first limiting plate 301. The connecting plate 307 is sleeved on the arc-shaped rod 308, and arc-shaped baffles 309 are provided at both ends. The arc-shaped rod 308 is installed on the first limiting plate 301. The baffles 309 are coaxial and of the same diameter as the first limiting plate 301 and are used to seal the gap at a higher position. When it is necessary to place the pipe on the clamping block 202, the connecting plate 307 is pushed upward to expose the gap at a higher position. Then the pipe is placed on the clamping block 202, and then the connecting plate 307 is pushed downward. The baffles 309 block the gap, and the inner wall of the baffles 309 contacts the pipe, thereby preventing the pipe from slipping. There is no need for the staff to manually limit the pipe.

[0024] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
