Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a pipe punching device. Background Technique

[0002] In the field of pipe processing, it is often necessary to punch holes in pipes to meet different usage requirements.

[0003] At present, there are some deficiencies in the existing pipe punching devices during use. For example, the clamping mechanism has poor stability and is difficult to adapt to pipes of different lengths and specifications; the adjustment of the punching angle is not flexible enough to meet the multi-angle punching requirements; at the same time, the working efficiency of the device also needs to be improved.

[0004] Therefore, we propose a pipe punching device. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a pipe punching device. In order to prevent problems such as unstable clamping, difficulty in adapting to pipes of different lengths and specifications, inflexible adjustment of the punching angle, and low working efficiency in the existing pipe punching devices during use, the stability and applicability of clamping are improved, the flexibility of angle adjustment is enhanced, and at the same time, the working efficiency is greatly improved, and the problems in the background technique can be effectively solved.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A pipe punching device includes a workbench. Two groups of relatively parallel triangular brackets are fixedly connected to the top end of the workbench. One end of the two groups of triangular brackets is rotationally connected to a rotating plate through a rotating shaft. A cross bar is provided at one end of the two groups of rotating plates away from the triangular brackets. A clamping mechanism is provided on the cross bar. The clamping mechanism includes an upper clamp and a lower clamp. The upper clamp and the lower clamp are rotationally connected through a rotating shaft, and one end of the lower clamp is inserted into the inside of a first installation groove at one end of the upper clamp. A fixing member is threadedly connected to one side of the upper clamp close to the first installation groove;

[0008] Threaded holes for installing adjusting bolts are respectively opened inside the upper clamp and the lower clamp. One end of the bolt passes through the threaded hole and is rotationally connected to an arc-shaped clamping plate. Second installation grooves which are relatively parallel are respectively opened on the inner sides of the upper clamp and the lower clamp. The second installation grooves are communicated with the threaded holes, and the arc-shaped clamping plate is adapted to the second installation grooves in size.

[0009] By adopting the above technical solution, the pipe to be punched is placed on the lower clamp, and then the upper clamp is closed, so that one end of the lower clamp is inserted into the first installation groove at one end of the upper clamp. By rotating the fixing member, the upper clamp and the lower clamp are fixed together, thus preliminarily fixing the pipe; Rotate the adjusting bolt, and the bolt rotates and advances forward in the threaded hole. Since one end of the bolt is rotatably connected to the arc-shaped clamping plate, and the arc-shaped clamping plate is installed in the second installation groove communicated with the threaded hole, the advancement of the bolt will cause the arc-shaped clamping plate to move in the second installation groove, and the arc-shaped clamping plate gradually approaches the surface of the pipe until it is in close contact with the pipe. The pipe is firmly clamped from both sides by the arc-shaped clamping plates in the upper clamp and the lower clamp;

[0010] After fixing the pipe with the clamping mechanism on the cross bar, since the rotating plate is rotatably connected to the triangular bracket through the rotating shaft, the angle of the rotating plate can be adjusted according to the punching requirements, and then the angle of the pipe can be adjusted, and the punching device is aligned with the clamped pipe for punching operation.

[0011] Further, the rotating plate is a vertically arranged disc structure, the cross bars are arranged in pairs symmetrically, the lower clamps are arranged in pairs symmetrically, and both groups of lower clamps are slidably connected to the outside of the two groups of cross bars. The clamping mechanisms and the cross bars are arranged in a plurality of groups in a circular array centered on the center of the rotating plate.

[0012] By adopting the above technical solution, the rotating plate is a vertically arranged disc structure, and this disc structure provides a stable support and rotation basis for the whole device. Since its shape is a disc, it has good stability and symmetry, can evenly bear the forces from all directions, and ensures that the device will not tilt or shake during the working process;

[0013] The cross bars are arranged in pairs symmetrically, and the lower clamps are also arranged in pairs symmetrically. This symmetrical arrangement enables the device to be more balanced in force when clamping the pipe, improving the stability of clamping; At the same time, both groups of lower clamps are slidably connected to the outside of the two groups of cross bars. This design enables the lower clamps to slide on the cross bars to adjust the position. In this way, in actual operation, according to the length and size of different pipes, the position of the lower clamps can be flexibly adjusted to adapt to the clamping requirements of different specifications of pipes;

[0014] The clamping mechanisms and the cross bars are arranged in a plurality of groups in a circular array centered on the center of the rotating plate. This circular array design has multiple advantages; First of all, it increases the number of pipes that the device can clamp at the same time, improving the working efficiency; Secondly, the circular array makes the clamping mechanisms evenly distributed on the rotating plate. When the rotating plate rotates, the pipes on each clamping mechanism can be adjusted at the same angle, ensuring the consistency of the punching angle; In addition, the circular array also provides more choices for punching at different angles, and the appropriate clamping mechanism can be selected for punching operation according to actual needs, improving the flexibility and applicability of the device.

[0015] Furthermore, a driving motor is fixedly installed on one side of one of the triangular brackets, and the output shaft of the driving motor penetrates through the triangular bracket and is fixedly connected to the center of the rotating plate.

[0016] By adopting the above technical solution, the driving motor is fixedly installed on one side of one of the triangular brackets. When it is necessary to adjust the angle of the pipe for drilling, the driving motor is started. The output shaft of the driving motor penetrates through the triangular bracket, and the output shaft is fixedly connected to the center of the rotating plate. When the driving motor works, its output shaft rotates. Since the output shaft is fixedly connected to the center of the rotating plate, it will drive the rotating plate to rotate around the center; and the rotating plate is a vertically arranged disc structure, the cross bar, the lower clamp and the clamping mechanism are all connected to the rotating plate, and the rotation of the rotating plate will drive the cross bar, the lower clamp and the pipe clamped on the clamping mechanism to rotate together, so as to realize the adjustment of the angle of the pipe, so as to drill the pipe at different angles.

[0017] Furthermore, limiting rods are fixedly connected to the opposite sides of the two arc-shaped clamping plates, and limiting grooves for slidably connecting the limiting rods are opened inside the upper clamp and the lower clamp.

[0018] By adopting the above technical solution, on the one hand, the limiting groove provides a specific moving track for the limiting rod, ensuring that the arc-shaped clamping plate maintains a stable direction during the moving process, without deviation or shaking, so that it can accurately move towards the pipe direction and uniformly apply a clamping force, ensuring that the pipe is firmly clamped between the arc-shaped clamping plates; on the other hand, the combination of the limiting rod and the limiting groove limits the moving range of the arc-shaped clamping plate, preventing the arc-shaped clamping plate from moving excessively and damaging the pipe, and also ensuring the reliability and safety of the clamping mechanism during use.

[0019] Furthermore, a support frame is fixedly installed at the top of the workbench, a sliding groove is opened at the top of the support frame, and a sliding seat is slidably connected inside the sliding groove.

[0020] By adopting the above technical solution, the sliding groove opened at the top of the support frame provides a specific moving track for the sliding seat, and the sliding seat can slide inside the sliding groove; during the working process of the pipe drilling device, the sliding of the sliding seat can realize different functions. For example, a drilling device can be installed on the sliding seat, and by adjusting the position of the sliding seat in the sliding groove, the drilling device can be moved to a suitable position to drill the pipe clamped on the clamping mechanism, making the position adjustment of the drilling device more flexible and convenient, and capable of adapting to different sizes of pipes and different drilling requirements.

[0021] Furthermore, a cylinder is fixedly installed at the top of the sliding seat, and the output end of the cylinder penetrates through the sliding seat and is fixedly installed with a drill bit.

[0022] By adopting the above technical solution, when it is necessary to punch holes in the pipe, the cylinder is activated, and its output end extends downward. Since the output end of the cylinder penetrates through the sliding seat and is fixedly installed with a punch head, the output end of the cylinder pushes the punch head downward. The punch head approaches and contacts the pipe clamped on the clamping mechanism under the push of the cylinder, and then punches the pipe under a certain pressure. By controlling the telescopic length and speed of the cylinder, the punching depth and punching efficiency of the punch head can be adjusted to meet different punching requirements.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] (1) For a pipe punching device of the utility model, the clamping mechanism of the pipe punching device includes an upper clamp and a lower clamp. After initially fixing the pipe through the rotating fixing member, the arc-shaped clamping plate is pushed by the adjusting bolt to firmly clamp the pipe from both sides. At the same time, the limiting rod on the arc-shaped clamping plate cooperates with the limiting grooves in the upper and lower clamps to ensure the stability and non-deviation of the clamping process, preventing damage to the pipe. In addition, the lower clamp can slide on the cross bar, which can adapt to pipes of different lengths and specifications, greatly improving the applicability of the device.

[0025] (2) For a pipe punching device of the utility model, the rotating plate in the device is a vertical disc structure. The rotating plate can be driven to rotate by the driving motor, thereby adjusting the angle of the pipe clamped on the clamping mechanism to meet the punching requirements at different angles. Moreover, there are multiple groups of clamping mechanisms and cross bars arranged in a circular array centered on the center of the rotating plate, which can clamp multiple pipes at the same time for punching operations, greatly improving the working efficiency. At the same time, the circular array design ensures the consistency of the punching angles, providing more choices for punching at different angles and making the device more flexible and practical.

Specific implementation manner

[0031] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0032] In order to prevent problems such as unstable clamping, difficulty in adapting to pipes of different lengths and specifications, inflexible adjustment of punching angles, and low work efficiency during the use of existing pipe punching devices, the stability and applicability of clamping are improved, the flexibility of angle adjustment is enhanced, and at the same time, the work efficiency is greatly improved. As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, a pipe punching device includes a workbench 1, two groups of relatively parallel triangular brackets 2 are fixedly connected to the top end of the workbench 1, one ends of the two groups of triangular brackets 2 are rotatably connected to a rotating plate 3 through a rotating shaft, a cross bar 12 is arranged at one end of the two groups of rotating plates 3 away from the triangular brackets 2, a clamping mechanism 4 is arranged on the cross bar 12, the clamping mechanism 4 includes an upper fixture 5 and a lower fixture 6, the upper fixture 5 and the lower fixture 6 are rotatably connected through a rotating shaft, and one end of the lower fixture 6 is inserted into the inside of a first installation groove 7 at one end of the upper fixture 5, and a fixing piece 8 is threadedly connected to one side of the upper fixture 5 close to the first installation groove 7;

[0033] Threaded holes for installing adjusting bolts 11 are respectively formed in the upper fixture 5 and the lower fixture 6, one end of the bolt 11 passes through the threaded hole and is rotatably connected to an arc-shaped clamping plate 9, second installation grooves 10 which are relatively parallel are respectively formed on the inner sides of the upper fixture 5 and the lower fixture 6, the second installation grooves 10 are communicated with the threaded holes, and the arc-shaped clamping plate 9 is adapted to the second installation grooves 10 in size.

[0034] During use, place the pipe to be punched on the lower clamp 6, then close the upper clamp 5, insert one end of the lower clamp 6 into the first installation groove 7 at one end of the upper clamp 5, and fix the upper clamp 5 and the lower clamp 6 together by rotating the fixing member 8, thereby initially fixing the pipe; rotate the adjusting bolt 11, the bolt 11 rotates and advances forward in the threaded hole. Since one end of the bolt 11 is rotatably connected to the arc-shaped clamping plate 9, and the arc-shaped clamping plate 9 is installed in the second installation groove 10 communicating with the threaded hole, the advancement of the bolt 11 will cause the arc-shaped clamping plate 9 to move in the second installation groove 10, and the arc-shaped clamping plate 9 gradually approaches the surface of the pipe until it is in close contact with the pipe. The pipe is firmly clamped from both sides by the arc-shaped clamping plates 9 in the upper clamp 5 and the lower clamp 6;

[0035] After fixing the pipe with the clamping mechanism 4 on the cross bar 12, since the rotating plate 3 is rotatably connected to the triangular bracket 2 through a rotating shaft, the angle of the rotating plate 3 can be adjusted according to the punching requirements, and then the angle of the pipe can be adjusted, and the punching device is aligned with the clamped pipe for punching operation.

[0036] Exemplarily, as Figure 2 shown, the present utility model further includes that the rotating plate 3 is a vertically arranged disc structure, the cross bars 12 are arranged in pairs symmetrically, the lower clamps 6 are arranged in pairs symmetrically, and both groups of lower clamps 6 are slidably connected to the outside of both groups of cross bars 12, and the clamping mechanism 4 and the cross bars 12 are both provided with multiple groups in a circular array centered on the center of the rotating plate 3.

[0037] During use, the rotating plate 3 is a vertically arranged disc structure, and this disc structure provides a stable support and rotation basis for the whole device. Due to its disc shape, it has good stability and symmetry, can evenly bear the forces from all directions, and ensures that the device will not tilt or shake during the working process;

[0038] The cross bars 12 are arranged in pairs symmetrically, and the lower clamps 6 are also arranged in pairs symmetrically. This symmetrical arrangement enables the device to be more balanced in force when clamping the pipe, improving the clamping stability; at the same time, both groups of lower clamps 6 are slidably connected to the outside of both groups of cross bars 12. This design enables the lower clamps 6 to slide and adjust their positions on the cross bars 12.

Second, the circular array makes the clamping mechanisms 4 evenly distributed on the rotating plate 3. When the rotating plate 3 rotates, the pipes on each clamping mechanism 4 can be adjusted at the same angle, ensuring the consistency of the drilling angle. In addition, the circular array also provides more options for drilling at different angles. The appropriate clamping mechanism 4 can be selected for drilling operations according to actual needs, improving the flexibility and applicability of the device.

[0040] Exemplarily, as Figure 1 shown, the present invention further includes that a driving motor 20 is fixedly installed on one side of one of the triangular brackets 2. The output shaft of the driving motor 20 penetrates through the triangular bracket 2 and is fixedly connected to the center of the rotating plate 3.

[0041] During use, the driving motor 20 is fixedly installed on one side of one of the triangular brackets 2. When it is necessary to adjust the angle of the pipe for drilling, the driving motor 20 is started. The output shaft of the driving motor 20 penetrates through the triangular bracket 2, and the output shaft is fixedly connected to the center of the rotating plate 3. When the driving motor 20 works, its output shaft rotates. Since the output shaft is fixedly connected to the center of the rotating plate 3, it will drive the rotating plate 3 to rotate around the center. The rotating plate 3 is a vertically arranged disc structure, and the crossbar 12, the lower clamp 6, and the clamping mechanism 4 are all connected to the rotating plate 3. The rotation of the rotating plate 3 will drive the crossbar 12, the lower clamp 6, and the pipe clamped on the clamping mechanism 4 to rotate together, so as to realize the adjustment of the angle of the pipe for drilling operations at different angles.

[0042] Exemplarily, as Figure 4 shown, the present invention further includes that limiting rods 19 are fixedly connected to the opposite sides of the two arc-shaped clamping plates 9, and limiting grooves 18 for slidably connecting the limiting rods 19 are formed inside the upper clamp 5 and the lower clamp 6.

On the other hand, the combination of the limiting rod 19 and the limiting groove 18 limits the moving range of the arc-shaped clamping plate 9, preventing the arc-shaped clamping plate 9 from moving excessively and damaging the pipe, and also ensuring the reliability and safety of the clamping mechanism 4 during use.

[0047] During use, when punching the pipe is required, the cylinder 16 is started, and its output end extends downward. Since the output end of the cylinder 16 penetrates through the sliding seat 15 and is fixedly installed with the punching head 17, the output end of the cylinder 16 pushes the punching head 17 to move downward.
