Description

Technical Field

[0001] The present application relates to the technical field of chuck clamping devices, and in particular to an auxiliary tool for clamping and centering a pipe for stability. Background Art

[0002] With the advancement of science and technology, more and more pipes are used in industrial production. In the processing operations such as cutting, bending or welding of pipes, in order to improve the processing quality of pipes and reduce the possibility of uneven cutting surface, inaccurate bending angle or rough welding points caused by shaking of pipes during processing, the pipes need to be clamped in a clamping device.

[0003] The existing clamping device is usually configured as a clamping jaw, into which the pipe is inserted, and the clamping jaw clamps the pipe so that the pipe can be cut, bent or welded under the stable clamping action of the clamping jaw. However, in actual operation, the end of the pipe away from the clamping jaw is prone to vibration under the processing action, which reduces the clamping stability of the pipe by the clamping jaw, resulting in poor processing quality of the pipe. Utility Model Content

[0004] In order to improve the stability of pipe clamping, the present application provides an auxiliary tool for pipe clamping and centering stability.

[0005] The present application provides an auxiliary tool for pipe clamping and centering stability, which adopts the following technical solution:

[0006] An auxiliary tool for clamping and centering a pipe stably comprises a base, the base is provided with a pipe insertion port, the base is slidably connected with a plurality of chucks, the chucks are circumferentially arranged around the pipe insertion port, the clamping direction of the chucks is toward the pipe insertion port, and the clamping end of the chuck is rotatably connected with a rotating part.

[0007] By adopting the above technical solution, the pipe clamped in the clamping jaws is inserted into the pipe insertion port, and the chuck slides on the base toward the pipe insertion port until the rotating member abuts against the pipe wall of the pipe, so that the pipe clamped in the clamping jaws is processed while the rotating members abut against each other, and the pipe is doubly clamped, which reduces the possibility of the pipe swaying during processing and improves the clamping stability of the pipe. At the same time, the rotating member is rotatably connected to the chuck, which facilitates the removal of the processed pipe from the auxiliary tool and speeds up the speed at which pipes of the same specification are stabilized in the auxiliary tool.

[0008] Optionally, the clamps are equidistantly arranged around the insertion opening.

[0009] By adopting the above technical solution, the chucks are evenly distributed around the pipe, so that the pipe is subjected to uniform force during the clamping process, the stability of the pipe clamping is improved, and the processing requirements of pipes of different specifications are met.

[0010] Optionally, the number of the chucks is four, and the four chucks are symmetrically arranged in pairs in a cross shape.

[0011] By adopting the above technical solution, the stability of pipe clamping is further enhanced, so that the pipe can be stably and reliably fixed on the clamping jaws during processing. When cutting, bending and other operations are performed on the pipe, the possibility of horizontal or vertical swinging of the pipe is reduced, thereby improving the processing quality of the pipe.

[0012] Optionally, adjacent rotating members are arranged in a staggered manner.

[0013] By adopting the above technical solution, the clamping area gradually decreases during the sliding of the chuck toward the pipe insertion port, and the adjacent rotating parts are staggered. In the process of the gradual reduction of the clamping area, the adjacent clamping parts will not be blocked, and the clamping area range of the clamping claws is expanded, thereby reducing the possibility that the rotating parts cannot contact the pipe due to the small size of the pipe, thereby improving the applicability of the auxiliary tool.

[0014] Optionally, the chuck includes a sliding member and a clamping member, the sliding member and the clamping member are detachably connected, the sliding member is slidingly connected to the base, and the clamping member is rotatably connected to the rotating member.

[0015] By adopting the above technical solution, it is convenient to regularly check the wear of the rotating parts and perform necessary replacement or maintenance, so that the clamping force of the rotating parts is always kept in the best state, thereby ensuring stability during the processing.

[0016] Optionally, a locking piece is provided on one side of the clamping piece, the locking piece is inserted into the clamping piece, the locking piece abuts against the clamping piece, and the locking piece is threadedly connected to the sliding piece.

[0017] By adopting the above technical solution, the clamping member is fixed on the sliding seat under the action of the locking member, which provides a reliable and stable fixing method for the installation of the clamping member, reduces the possibility of movement or vibration of the clamping member during the pipe processing, and further improves the clamping stability of the pipe.

[0018] Optionally, the base is provided with mounting openings, and the mounting openings are equidistantly arranged circumferentially around the insertion opening.

[0019] By adopting the above technical solution, the installation openings are equidistantly arranged in the circumferential direction, so that the load can be evenly distributed during the installation of the base, reducing local stress concentration, thereby improving the durability and life of the base. At the same time, the possibility of swaying of the base due to uneven force is reduced, the installation stability of the base is improved, and the stability of the auxiliary tool in clamping the pipe is improved.

[0020] Optionally, the base is connected to a length measuring device, which is located on one side of the clamping direction of the chuck and is used to measure the sliding distance of the chuck on the base.

[0021] By adopting the above technical solution, the length measuring device accurately measures the sliding distance of the chuck to ensure that the position of the chuck on the base is accurate. By using the length measuring device, it can be ensured that the sliding distance of the chuck is consistent each time, thereby improving the consistency and predictability of the production process.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The pipe clamped in the clamp is inserted into the pipe insertion port, and the chuck slides on the base toward the pipe insertion port until the rotating part abuts against the pipe wall of the pipe, so that the pipe clamped in the clamp is processed under the condition that the rotating parts abut against each other, and the pipe is double clamped, which reduces the possibility of the pipe swinging during processing and improves the clamping stability of the pipe. At the same time, the rotating part is rotatably connected with the chuck, which facilitates the removal of the processed pipe from the auxiliary tool and speeds up the stabilization of the pipes of the same specification in the auxiliary tool;

[0024] 2. As the chuck slides toward the pipe insertion port, the clamping area gradually decreases. Adjacent rotating parts are staggered. As the clamping area gradually decreases, adjacent clamping parts will not block each other. The clamping area of ​​the clamping jaws is expanded, which reduces the possibility that the rotating parts cannot contact the pipe due to small pipe size specifications, and improves the applicability of the auxiliary tool.

[0025] 3. The length measuring device accurately measures the sliding distance of the chuck to ensure that the position of the chuck on the base is accurate. By using the length measuring device, it can be ensured that the sliding distance of the chuck is consistent each time, thereby improving the consistency and predictability of the production process.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses an auxiliary tool for clamping and centering a pipe to stabilize the pipe.

[0033] Reference Figure 1 and Figure 2 A tool for clamping and centering a pipe, comprising a base 1, a pipe insertion port 11 is formed through one side of the base 1, a plurality of chucks 2 are slidably connected to the base 1, the chucks 2 are circumferentially arranged around the pipe insertion port 11, the clamping direction of the chucks 2 is toward the pipe insertion port 11, a chuck slot is formed at the clamping end of the chuck 2, a fixed rod 21 is arranged in the chuck slot, the fixed rod 21 is fixed to the chuck 2, a plurality of fixed rings 22 are arranged on the outer wall of the fixed rod 21, and the side wall of the fixed ring 22 is rolled. The movable connection is provided with a plurality of balls 23 which are equidistantly arranged circumferentially. A rotating part 3 is matched on the outer side of each fixed ring 22. The rotating part 3 is annular and concentric with the fixed ring 22. An annular groove 31 is provided on the inner wall of the rotating part 3. The balls 23 are located in the annular groove 31 and roll with the rotating part 3. Adjacent rotating parts 3 abut against each other. The rotating parts 3 located at both ends abut against the chuck 2 respectively. The chuck 2 is rotatably connected to the rotating part 3 through the fixed rod 21 and the balls 23.

[0034] When the pipe clamped in the clamping jaws is inserted into the pipe insertion port 11, the chuck 2 slides on the base 1 toward the pipe insertion port 11 until the rotating member 3 abuts against the pipe wall of the pipe, so that the pipe clamped in the clamping jaws is processed under the abutment state of the rotating member 3, and the pipe is double-clamped, which reduces the possibility of the pipe swaying during processing and improves the clamping stability of the pipe. At the same time, when the pipe moves, the pipe can drive the rotating member 3 to move under the rotation of the ball 23, so that the rotating member 3 and the chuck 2 rotate relative to each other, which is convenient for removing the processed pipe from the auxiliary tool and speeding up the speed at which the pipes of the same specification are stabilized in the auxiliary tool.

[0035] Reference Figure 3 A length measuring device 4 is fixedly connected to one side of the base 1 close to the rotating member 3. The length measuring device 4 is located on one side of the clamping direction of the chuck 2 and is used to measure the sliding distance of the chuck 2 on the base 1. In this embodiment, the length measuring device 4 is a ruler.

[0036] When the rotating member 3 abuts against the pipe, the sliding distance of the chuck 2 on the base 1 is measured by the length measuring device 4. According to the distance movement measurement value of each chuck 2, it can be judged whether the position of the pipe in the clamp and the position in the auxiliary tool are aligned. If the measured values ​​are consistent, the pipe is centered; if not, it is offset.

[0037] The chucks 2 are equidistantly arranged around the pipe insertion opening 11 , and are evenly distributed around the pipe, so that the pipe is subjected to uniform force during the clamping process, thereby improving the stability of the pipe clamping and meeting the processing requirements of pipes of different specifications.

[0038] In this embodiment, four chucks 2 are provided, and the four chucks 2 are symmetrically arranged in a cross shape. When processing the pipe, the rotating member 3 limits the position of the pipe in the vertical and horizontal directions, further enhancing the stability of the pipe clamping.

[0039] The chuck 2 includes a sliding member 24 and a clamping member 25, the sliding member 24 and the clamping member 25 are detachably connected, one end of the sliding member 24 away from the clamping member 25 is slidingly connected to the base 1, one end of the clamping member 25 away from the sliding member 24 is fixed to the fixed rod 21, and the clamping member 25 is rotatably connected to the rotating member 3 through the fixed rod 21 and the ball 23.

[0040] When the rotating part 3 is damaged, the clamping part 25 is disassembled from the sliding part 24, which is convenient for regular inspection of the wear of the rotating part 3 and necessary replacement or maintenance, so that the clamping force of the rotating part 3 is always maintained in the best state, thereby ensuring stability during the processing.

[0041] A locking member 26 is disposed on one side of the clamping member 25 away from the base 1 . The locking member 26 is inserted into the clamping member 25 , the locking member 26 abuts against the clamping member 25 , and the locking member 26 is threadedly connected to the sliding member 24 .

[0042] When the clamping member 25 is installed on the sliding member 24, the locking member 26 is inserted into the clamping member 25, and the locking member 26 screws the clamping member 25 onto the sliding member 24. The clamping member 25 is fixed on the sliding seat under the action of the locking member 26, which provides a reliable and stable fixing method for the installation of the clamping member 25, reduces the possibility of movement or vibration of the clamping member 25 during the pipe processing, and further improves the clamping stability of the pipe.

[0043] During the sliding process of the sliding member 24 toward the insertion port 11, the clamping area of ​​the clamping member 25 gradually decreases. In order to improve the applicability of the auxiliary tool, the lengths of adjacent clamping members 25 are inconsistent, and the distances from adjacent rotating members 3 to the base 1 are inconsistent, and they are staggered. In the process of gradually reducing the clamping area, the adjacent clamping members 25 will not be blocked, and the clamping area range of the clamping claws is expanded, thereby reducing the possibility that the rotating member 3 cannot contact the pipe due to the small size of the pipe.

[0044] The base 1 is provided with a mounting opening 12 for mounting the base 1 on the clamping jaws, and the mounting openings 12 are equidistantly arranged circumferentially around the insertion opening 11. By equidistantly arranging the mounting openings 12 circumferentially, the load can be evenly distributed on the base 1 during the installation process of the base 1, thereby reducing local stress concentration and improving the durability and life of the base 1.

[0045] The implementation principle of the auxiliary tool for clamping and centering the pipe in the embodiment of the present application is as follows: when the pipe clamped in the clamping jaws is inserted into the pipe insertion port 11, the sliding member 24 slides on the base 1 toward the pipe insertion port 11 until the rotating member 3 abuts against the pipe wall of the pipe, so that the pipe clamped in the clamping jaws is processed in the abutting state of the rotating member 3, and the pipe is double clamped, which reduces the possibility of the pipe swaying during processing and improves the clamping stability of the pipe; the clamping member 25 is rotatably connected to the rotating member 3 under the action of the fixed rod 21 and the ball 23, so that it is convenient to remove the processed pipe from the auxiliary tool, and when the pipe is inserted into the pipe insertion port 11, the speed of stabilizing the pipe of the same specification in the auxiliary tool is accelerated; a length measuring device 4 is provided, and whether the pipe is centered is judged by the sliding distance of the sliding member 24, so that the pipe is stably centered under the action of the rotating member 3 and the length measuring device 4, and the clamping stability of the pipe is improved.

[0046] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
