Description

Technical Field

[0001] This utility model relates to an adaptive pipe stabilizer for pressing down pipe fittings, mainly used for pressing down pipe fittings during the grooving process. Background Technology

[0002] During the grooving process, in addition to the pipe rotating around its own axis, it is necessary to keep the pipe stable in order to effectively complete the grooving process. However, there is currently no pipe stabilizer that can effectively hold the pipe in place during the grooving process, which causes inconvenience to the pipe grooving process. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the existing technology and to provide an adaptive pipe stabilizer for pressing down pipes that has a reasonable structural design and is easy to use.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The structural features of the adaptive pipe stabilizer for pressing down pipes are: it includes clamping rollers, a left clamping arm, a movable support arm, a drive device, a right clamping arm, a support pin, and a housing. The housing is a hollow structure, and the housing is provided with a set of left limiting grooves and a set of right limiting grooves. The lower ends of the left and right clamping arms are both connected to clamping rollers. The upper ends of the left and right clamping arms are respectively provided with left and right limiting protrusions. The left clamping arm rotates through the support pin. The left clamping arm is connected to the left side of the housing, with its left limiting protrusion located in the left limiting groove. The right clamping arm is rotatably connected to the right side of the housing via a support pin, with its right limiting protrusion located in the right limiting groove. The movable support arm is located inside the housing, with horizontal sliding grooves at both its left and right ends. The left limiting protrusion in the left clamping arm and the right limiting protrusion in the right clamping arm are located in the sliding grooves at the left and right ends of the movable support arm, respectively. The drive device is mounted on the housing and connected to the movable support arm.

[0005] Preferably, both the left clamping arm and the right clamping arm of this invention are arc-shaped structures.

[0006] Preferably, the left and right limiting grooves on the housing of this utility model are both arc-shaped structures, and the left and right limiting grooves form an inverted figure-eight shape.

[0007] Preferably, the connection between the left clamping arm and the housing is located near the upper end of the left clamping arm, and the connection between the right clamping arm and the housing is located near the upper end of the right clamping arm.

[0008] Preferably, the clamping rollers located at the lower end of the left clamping arm and the clamping rollers located at the lower end of the right clamping arm are flush.

[0009] Compared with the prior art, this utility model has the following advantages and effects: it can conveniently and effectively stabilize the pipe during the grooving process. The drive device drives the movable support arm to move up and down, so that the clamping rollers at the lower ends of the left and right clamping arms can move closer or further apart. That is, the distance between the clamping rollers at the lower ends of the left and right clamping arms can be adjusted to adapt to pipes of different diameters. When the distance between the clamping rollers at the lower ends of the left and right clamping arms matches the diameter of the pipe to be processed, the pipe to be processed is pressed down by the clamping rollers at the lower ends of the left and right clamping arms. Since the clamping rollers at the lower ends of the left and right clamping arms are rotatable, they do not affect the rotation of the pipe to be processed. Thus, the pipe to be processed can be pressed down during the grooving process to stabilize the pipe and improve processing stability. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0017] Example

[0018] See Figures 1 to 4 The adaptive pipe stabilizer for pressing down the pipe in this embodiment includes a clamping roller 1, a left clamping arm 2, a movable support arm 3, a drive device 4, a right clamping arm 5, a support pin 6, and a housing 7. The left clamping arm 2 and the right clamping arm 5 are both arc-shaped structures.

[0019] In this embodiment, the shell 7 is a hollow structure. The shell 7 is provided with a set of left limiting grooves 8 and a set of right limiting grooves 9. The left limiting grooves 8 and right limiting grooves 9 on the shell 7 are both arc-shaped structures, and the left limiting grooves 8 and right limiting grooves 9 form an inverted V-shape.

[0020] In this embodiment, the lower ends of the left clamping arm 2 and the right clamping arm 5 are both connected to clamping rollers 1. The clamping rollers 1 are rotatable, and the clamping rollers 1 located at the lower ends of the left clamping arm 2 and the right clamping arm 5 are flush.

[0021] In this embodiment, the upper end of the left clamping arm 2 is provided with a left limiting protrusion 11. The left clamping arm 2 is rotatably connected to the left part of the housing 7 via a support pin 6, and the connection between the left clamping arm 2 and the housing 7 is close to the upper end of the left clamping arm 2. The left clamping arm 2 can rotate around the connected support pin 6. The left limiting protrusion 11 on the left clamping arm 2 is located in the left limiting groove 8. When the left limiting protrusion 11 on the left clamping arm 2 moves along the left limiting groove 8, the left clamping arm 2 will rotate accordingly.

[0022] In this embodiment, the upper end of the right clamping arm 5 is provided with a right limiting protrusion 12. The right clamping arm 5 is rotatably connected to the right side of the housing 7 via a support pin 6, and the connection between the right clamping arm 5 and the housing 7 is near the upper end of the right clamping arm 5. The right clamping arm 5 can rotate around the connected support pin 6. The right limiting protrusion 12 on the right clamping arm 5 is located in the right limiting groove 9. When the right limiting protrusion 12 on the right clamping arm 5 moves along the right limiting groove 9, the right clamping arm 5 will rotate accordingly.

[0023] In this embodiment, the movable support arm 3 is located inside the housing 7. Both the left and right ends of the movable support arm 3 are provided with horizontal grooves. The left limiting protrusion 11 in the left clamping arm 2 and the right limiting protrusion 12 in the right clamping arm 5 are respectively located in the grooves at the left and right ends of the movable support arm 3. That is, the groove fork at the left end of the movable support arm 3 rests on the left limiting protrusion 11 of the left clamping arm 2, and the groove fork at the right end of the movable support arm 3 rests on the right limiting protrusion 12 of the right clamping arm 5. On the protrusion 12, when the movable support arm 3 moves up and down, the slide groove at the left end of the movable support arm 3 will push the left limiting protrusion 11 of the left clamping arm 2 to move along the left limiting groove 8, and the slide groove at the right end of the movable support arm 3 will push the right limiting protrusion 12 of the right clamping arm 5 to move along the right limiting groove 9, thereby realizing the rotation of the left clamping arm 2 and the right clamping arm 5, and achieving the purpose of adjusting the distance between the clamping roller 1 at the lower end of the left clamping arm 2 and the clamping roller 1 at the lower end of the right clamping arm 5.

[0024] In this embodiment, the drive device 4 is mounted on the housing 7. The drive device 4 is connected to the movable support arm 3, and the movable support arm 3 can be controlled to move up and down through the drive device 4.

[0025] Clamping rollers 1 are respectively installed in the left clamping arm 2 and the right clamping arm 5. The drive device 4 drives the movable support arm 3 to move up and down. The movable support arm 3 drives the left clamping arm 2 and the right clamping arm 5 to rotate, so that the two clamping rollers 1 are close to the pipe to be processed 10 according to the pipe diameter, so that the pipe to be processed 10 remains stable during the grooving process. Figure 3 and Figure 4 It can be seen that by adjusting the distance between the clamping roller 1 at the lower end of the left clamping arm 2 and the clamping roller 1 at the lower end of the right clamping arm 5 through the drive device 4, it is possible to adapt to pipe fittings 10 with different diameters. It is convenient to use and can effectively stabilize the pipe fittings 10 during the grooving process.
