Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a clamp. Background Art

[0002] Pipe fittings have the characteristics of light weight, corrosion resistance, high compressive strength, long service life, and easy installation, and are favored by the pipeline engineering industry. In actual projects, in order to facilitate installation, special equipment is usually required to punch holes in pipe fittings. For example, the authorization announcement number CN220373423U is a utility model patent for a punching device for pipe fitting processing, including a base, a door frame is fixedly installed on the base, a slide groove is opened on the top of the door frame, a cylinder is slidably installed on the door frame, the driving end of the cylinder slides in the slide groove, the driving end of the cylinder is fixedly connected to a connecting seat, a small motor is fixedly installed in the connecting seat, and two clamps are slidably installed in the rectangular groove. A driving assembly is provided on the door frame for driving the cylinder to slide, and a transmission assembly is provided on one side of the base for driving the clamp to slide. When the utility model is in use, the two clamps are close to each other to clamp and fix pipe fittings of different diameters to prevent the pipe fittings from shaking during the punching process and affecting the punching effect. By controlling the driving motor, the spacing of the openings can be controlled.

[0003] However, when processing other sides of the pipe fitting, the above-mentioned equipment needs to first release the clamping block, then manually rotate the pipe fitting, and finally fix the pipe fitting with the clamping block. During the rotation process, since there is no support point, the pipe fitting is easy to deviate along its own axial direction, which can easily cause the hole position to shift, so that the hole positions are not on the same cross section, which is not conducive to subsequent installation. Utility Model Content

[0004] In view of this, it is necessary to provide a clamp to solve the technical problem that the clamp in the prior art cannot ensure that the pipe will not deviate along its own axis during rotation.

[0005] The utility model provides a clamp, comprising:

[0006] A base, wherein a clearance hole is formed on the top of the base;

[0007] A rotating tube, the outer wall of which is rotatably sleeved on the clearance hole, and a blind hole is opened on the outer wall of the rotating tube;

[0008] A clamping member connected to one end of the rotating tube and used to fix the tube;

[0009] A fastener is detachably connected to the blind hole and is used to fix the rotating tube.

[0010] In one embodiment, a first threaded hole and a second threaded hole are respectively formed in the top end and the side wall of the base, and both the first threaded hole and the second threaded hole communicate with the relief hole.

[0011] In one embodiment, the number of the blind holes is more than two, and the blind holes are arranged at equal intervals around the cross section of the rotating tube, and each blind hole and the first threaded hole are located in the same cross section.

[0012] In one embodiment, a plurality of platforms are formed at positions adjacent to each of the blind holes, and the platforms are arranged at equal intervals around the cross section of the rotating tube, and each platform and the second threaded hole are located in the same cross section.

[0013] In one embodiment, the fastener includes a first screw and a second screw. The first screw is threadedly connected to the first threaded hole and abuts against any one of the platforms, and the second screw is threadedly connected to the second threaded hole and inserted into any one of the blind holes.

[0014] In one embodiment, the clamping member includes a first clamping block, a second clamping block and a bolt. The second clamping block is fixedly connected to the end of the rotating tube, and the first clamping block is connected to the second clamping block through the bolt.

[0015] In one embodiment, a limiting ring is provided at the end of the rotating tube away from the clamping member.

[0016] In one embodiment, a slideway and a limiting rod are provided below the relief hole. The slideway is fixedly connected to the base, one end of the limiting rod is slidably sleeved in the slideway, and the other end of the limiting rod abuts against the end of the pipe fitting.

[0017] In one embodiment, a third threaded hole is formed in the side wall of the slideway, and a third screw is threadedly connected to the third threaded hole. The third screw is used to abut against the side wall of the limiting rod.

[0018] In one embodiment, reinforcing ribs are fixedly connected to opposite sides of the base.

[0019] Compared with the prior art, a fixture provided by the utility model has the following beneficial effects:

[0020] On the one hand, by rotatably sleeving the rotating tube in the relief hole, connecting the clamping member to one end of the rotating tube, and detachably connecting the fastener to the blind hole, the pipe fitting can rotate along with the rotation of the rotating tube and is fixed by the fastener.

[0021] On the other hand, by respectively engaging the two ends of the rotating tube with the two ends of the clearance hole, the rotating tube will not move along its own axis when driving the pipe to rotate, thus avoiding deviation in the punching position;

[0022] To sum up, when it is necessary to punch holes on different sides of a pipe fitting, the worker does not need to release the clamping parts. The worker can directly adjust the angle of the rotating pipe, which effectively avoids the position deviation caused by manual rotation and re-fixing of the pipe fitting, ensures that each hole is located in the same cross-section, and effectively improves the quality of the punching of the pipe fitting.

[0030] The preferred embodiments of the present utility model will be specifically described below in conjunction with the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principles of the present utility model, rather than to limit the scope of the present utility model.

[0031] Please refer to Figures 1 - 4 , the present utility model provides a fixture, including:

[0032] A base 1, with a relief hole 11 opened at the top of the base 1;

[0033] A rotating tube 2, the outer wall of the rotating tube 2 is rotatably sleeved in the relief hole 11, and a blind hole 21 is opened on the outer wall of the rotating tube 2;

[0034] A clamping member 3, the clamping member 3 is connected to one end of the rotating tube 2 and is used to fix the pipe fitting 5;

[0035] A fastener 4, the fastener 4 is detachably connected to the blind hole 21 and is used to fix the rotating tube 2.

[0036] Specifically, on the one hand, by rotatably sleeving the rotating tube 2 in the relief hole 11, connecting the clamping member 3 to one end of the rotating tube 2, and detachably connecting the fastener 4 to the blind hole 21, the pipe fitting 5 can rotate with the rotation of the rotating tube 2 and is fixed by the fastener 4;

[0037] On the other hand, by clamping the two ends of the rotating tube 2 to the two ends of the relief hole 11 respectively, the rotating tube 2 will not displace along its own axis direction during the process of driving the pipe fitting 5 to rotate, avoiding the deviation of the punching position;

[0038] In summary, when it is necessary to punch different sides of the pipe fitting 5, the staff does not need to release the fixation of the clamping member 3. The staff can directly adjust the angle of the rotating tube 2, effectively avoiding the position deviation caused by re-fixing after manually rotating the pipe fitting 5, ensuring that each hole position is located in the same cross-section, and effectively improving the punching quality of the pipe fitting 5.

[0039] First, the end of the pipe fitting 5 is inserted into the rotating tube 2; then, the staff adjusts the clamping member 3 to make the pipe fitting 5 fixed; finally, the rotating tube 2 is rotated until the pipe fitting 5 rotates into a preset state, and the rotation of the rotating tube 2 is restricted by connecting the fastener 4 to the blind hole 21 to ensure that the pipe fitting 5 is stable during the punching process.

[0040] It should be noted that the base 1 is fixedly connected to the working platform of the punching device through bolts 33.

[0041] Furthermore, in order to improve the stability of the pipe fitting 5 during the punching process, there are two of this utility model, which are respectively connected to the two ends of the pipe fitting 5.

[0042] Further, in this embodiment, a first threaded hole 111 and a second threaded hole 112 are respectively formed at the top end and the side wall of the base 1, and both the first threaded hole 111 and the second threaded hole 112 communicate with the relief hole 11.

[0043] Further, in this embodiment, the number of the blind holes 21 is more than two, and the blind holes 21 are arranged at equal intervals around the cross section of the rotating pipe 2, and each blind hole 21 and the first threaded hole 111 are located in the same cross section.

[0044] Further, in this embodiment, a plurality of platforms 22 are formed at the adjacent positions of the blind holes 21, and the platforms 22 are arranged at equal intervals around the cross section of the rotating pipe 2, and each platform 22 and the second threaded hole 112 are located in the same cross section.

[0045] Further, in this embodiment, the fastener 4 includes a first screw 41 and a second screw 42. The first screw 41 is threadedly connected to the first threaded hole 111 and abuts against any one of the platforms 22, and the second screw 42 is threadedly connected to the second threaded hole 112 and inserted into any one of the blind holes 21. Specifically, on the one hand, through the threaded connection of the first screw 41 with the first threaded hole 111, when the rotating pipe 2 rotates to any direction, the rotating pipe 2 can be fixed by the first screw 41 abutting against the platform 22. On the other hand, through the threaded connection of the second screw 42 with the second threaded hole 112, when the rotating pipe 2 rotates to any direction, the rotating pipe 2 can also be fixed by the second screw 42 inserted into the blind hole 21. The above two fixing methods jointly limit the rotation of the rotating pipe 2 and ensure that the pipe fitting 5 does not shift during the punching process.

[0046] Even further, in order for the first screw 41 to better abut against any one of the platforms 22, the end of the first screw 41 facing the platform 22 is a flat surface.

[0047] Even further, in order to strengthen the connection between the second screw 42 and the blind hole 21, the blind hole 21 also adopts a threaded hole consistent with the second threaded hole 112, so that the second screw 42 and the blind hole 21 form a threaded connection, and the rotation of the rotating pipe 2 is more stably restricted.

[0048] Even further, in order to facilitate the operation of the staff, a handle is provided at the end of the second screw 42 away from the rotating pipe 2, and the staff can manually rotate the second screw 42 through the handle.

[0049] Further, in this embodiment, the clamping member 3 includes a first clamping block 31, a second clamping block 32 and a bolt 33. The second clamping block 32 is fixedly connected to the end of the rotating pipe 2, and the first clamping block 31 is connected to the second clamping block 32 through the bolt 33. Specifically, by adjusting the bolt 33, the distance between the first clamping block 31 and the second clamping block 32 can be changed, so that the clamping member 3 is applicable to pipe fittings 5 with different diameters.

[0050] Furthermore, in this embodiment, a stop ring 23 is provided at the end of the rotating tube 2 away from the clamping member 3. Specifically, the stop ring 23 prevents the rotating tube 2 from being separated from the clearance hole 11, so that the rotating tube 2 cannot move along its own axis during the rotation process, thereby ensuring the positioning of the pipe 5.

[0051] Furthermore, in this embodiment, a slideway 12 and a stopper rod 13 are provided below the positioning hole 11, the slideway 12 is fixedly connected to the base 1, one end of the stopper rod 13 is slidably sleeved in the slideway 12, and the other end of the stopper rod 13 abuts against the end of the pipe 5. Specifically, under the effect of the abutment between the end of the stopper rod 13 and the end of the pipe 5, it is further ensured that the pipe 5 cannot move along its own axial direction.

[0052] Furthermore, a limiting plate 131 is provided at the end of the limiting rod 13 abutting against the pipe 5 , so as to facilitate the limiting rod 13 to limit the movement of the pipe 5 along the axial direction.

[0053] Further, in the present embodiment, a third threaded hole 121 is provided on the side wall of the slideway 12, and a third screw 122 is threadedly connected to the third threaded hole 121, and the third screw 122 is used to abut against the side wall of the limiting rod 13. Specifically, when the limiting rod 13 needs to be moved, the third screw 122 is rotated to move the third screw 122 in a direction away from the limiting rod 13, and when the limiting rod 13 needs to be fixed, the third screw 122 is rotated to move the third screw 122 toward the limiting rod 13 until the third screw 122 abuts against the side wall of the limiting rod 13, so that the limiting rod 13 cannot move.

[0054] Furthermore, in this embodiment, two opposite sides of the base 1 are fixedly connected with reinforcing ribs 14. Specifically, the function of the reinforcing ribs 14 is to improve the stability of the base 1.

[0055] The specific working process of the utility model is as follows: first, determine that the positions of the two relative bases 1 are stable and immovable; then, insert the two rotating tubes 2 at the two ends of the pipe fitting 5 respectively; then, the staff adjusts the bolt 33 so that the first clamping block 31 and the second clamping block 32 clamp the pipe fitting 5 to make it immovable; secondly, rotate the rotating tube 2 until the pipe fitting 5 is rotated into a preset state, and then the first screw 41 abuts against any platform 22 and the second screw 42 is threadedly connected with any blind hole 21 to limit the rotating tube 2 from continuing to rotate, so as to ensure that the pipe fitting 5 is stable and immovable during the punching process; finally, adjust the limiting rod 13 so that the two limiting plates 131 abut against the two ends of the pipe fitting 5 respectively, and rotate the third screw 122 to make the limiting rod 13 immovable, that is, fix the pipe fitting 5, and start punching;

[0056] When it is necessary to punch holes in different sides of the pipe fitting 5, release the restrictions of the first screw 41 and the second screw 42, rotate the rotating pipe 2, and the pipe fitting 5 will rotate along with the rotation of the rotating pipe 2 under the action of the clamping member 3.

[0057] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
