Description

Technical Field

[0001] The utility model relates to the technical field of processing reducer pipes, in particular to a groove clamp for processing the end faces of reducer and reducer pipes. Background Art

[0002] A reducer is a type of pipe fitting used at the point where the pipe changes diameter. The commonly used forming processes are reducing and pressing, expanding and pressing, or reducing and expanding. For reducers of certain specifications, stamping can also be used.

[0003] When the existing reducer is processed, it needs to be clamped. Since the reducer has two ends, a large end and a small end, the existing clamp usually clamps the small end first and then the large end when clamping it. Moreover, when clamping, the screw is usually rotated manually to drive the clamping plates to approach each other for clamping. This clamping method wastes manpower and wastes time when clamping and removing.

[0004] Based on this, we propose a beveling fixture for processing the end faces of reducers. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 4 A groove fixture for processing the end surface of the reducer head of a reducer comprises a base 1, and a workbench 2 is fixedly connected to the upper end of the base 1;

[0027] The clamping mechanism includes a slide groove 3, a slider 4, a mounting rod 5, a fixing rod 6, a mounting block 7, a vertical groove 8, a vertical rod 9, an arc block 10, a groove 11, an arc fixing plate 12 and an air pump component. A slide groove 3 is provided at the upper end of the workbench 2. Two slide blocks 4 are symmetrically and slidably connected to the inner wall of the slide groove 3. The upper ends of the two slide blocks 4 are fixedly connected with the mounting rod 5. The side wall of the mounting rod 5 is fixedly connected with the fixing rod 6. The side wall of the fixing rod 6 is fixedly connected with the mounting block 7. The side wall of the mounting block 7 is symmetrically provided with two vertical grooves 8. The inner walls of the two vertical grooves 8 are sealed and slidably connected with the vertical rod 9. The end of the vertical rod 9 away from the mounting block 7 is fixedly connected with the arc block 10. The side wall of the arc block 10 is provided with a groove 11. The inner wall of the groove 11 is slidably connected with the arc fixing plate 12. A air pump component is installed on the base 1.

[0028] The clamping mechanism also includes a plurality of first springs 13 fixedly connected to the inner wall of the groove 11, and the other ends of the plurality of first springs 13 are fixedly connected to the arc-shaped fixing plate 12. When the arc-shaped fixing plate 12 clamps the inner wall of the reducer, the first springs 13 will be compressed first, thereby providing a buffer to prevent the inner wall of the reducer from being suddenly stressed and causing the reducer to be squeezed and deformed.

[0029] The driving assembly includes a box body 14 fixedly connected to the upper end of the base 1, and a sliding plug 15 is sealingly and slidably connected to the inner wall of the box body 14. A cavity 141 is opened in the mounting block 7, and the vertical grooves 8 are connected to the cavity 141. The box body 14 is connected to the two cavities 141 respectively through branch pipes 16, and the branch pipes 16 are made of hoses.

[0030] The driving assembly further includes an electric push rod 17 fixedly connected to the side wall of the box body 14 , and a movable end of the electric push rod 17 penetrates the side wall of the box body 14 and is fixedly connected to the sliding plug 15 .

[0031] It should be noted that a through hole is opened on the inner wall of the box body 14 close to the electric push rod 17. When the sliding plug 15 slides in a sealed manner, the through hole can balance the pressure inside the box body 14 to ensure that the sliding plug 15 can slide normally.

[0032] A limiting ring 22 is fixedly connected to the inner wall of the vertical groove 8 , and a second spring 23 is fixedly connected between the limiting ring 22 and the vertical rod 9 .

[0033] The inner wall of the slide groove 3 is rotatably connected with a bidirectional screw 18, and the side wall of the bidirectional screw 18 is threadedly connected with the two sliders 4. One end of the bidirectional screw 18 passes through the side wall of the workbench 2 and is fixedly connected with a hand 19, on which a limit position assembly is installed.

[0034] The limit assembly includes a threaded rod 20 threadedly connected to the side wall of the handle 19, and a plurality of thread grooves 21 are opened on the side wall of the workbench 2, and the plurality of thread grooves 21 are symmetrically arranged along the axis of the bidirectional lead screw 18. By rotating the threaded rod 20 into the thread groove 21, the rotation position of the bidirectional lead screw 18 is limited, thereby preventing the bidirectional lead screw 18 from rotating, driving the arc-shaped fixed plate 12 to move, and causing the clamping of the reducer to fail.

[0035] In the utility model, the small end of the reducer is firstly sleeved on the arc-shaped fixed plate 12, and then the handle 19 is rotated to drive the bidirectional lead screw 18 to rotate, drive the two sliders 4 to slide close to each other, and then drive the two mounting rods 5 to approach each other, drive the arc-shaped fixed plate 12 to approach each other, so that the large end of the reducer is also sleeved on the arc-shaped fixed plate 12 on the other side, and then the threaded rod 20 is turned into the corresponding threaded groove 21 to limit the rotation position of the bidirectional lead screw 18.

[0036] Then, the electric push rod 17 is driven to extend, driving the sliding plug 15 to slide in a sealed manner in the box body 14, and the air in the box body 14 is squeezed into the cavity 141 through the branch pipe 16, and then the air will enter the vertical groove 8, pushing the vertical rod 9 to slide outward, and then the arc-shaped fixing plate 12 will approach the inner wall of the reducer and fit with the inner wall of the reducer, thereby tightly clamping the reducer, and then the reducer can be processed.

[0037] After the processing is completed, it is only necessary to drive the electric push rod 17 to retract and drive the sliding plug 15 to reset, and then the air in the vertical groove 8 will be drawn back into the box body 14 through the branch pipe 16, and then the arc-shaped fixing plate 12 will be reset under the action of the second spring 23, and will no longer fit the inner wall of the reducer, so that the reducer can be removed.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
