[0001] The utility model relates to the technical field of mechanical processing brackets, and specifically relates to a bracket for mechanical processing. Background Art

[0002] Mechanical processing is a step in workpiece or part manufacturing and processing. Using mechanical processing methods to directly change the shape, size, surface quality, etc. of the blank, and the process of making it into a part is called the mechanical processing technological process. When processing pipe fittings, a roller support bracket is usually required for support. The existing roller support bracket includes a bottom plate, a height adjustment member, and two groups of rollers.

[0003] According to the above, the existing roller support bracket has the following deficiencies when in use:

[0004] Although the bracket can meet height adjustment, when the distance between the two rollers needs to be adjusted, the movement of the two rollers needs to be carried out individually. At the same time, there are many bolts. When fixing the rollers, several bolts need to be screwed, resulting in increased operation repetition, increased operation time, and inconvenience. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a bracket for mechanical processing, which is convenient for adjusting the distance between the rollers.

[0006] To achieve the above object, the utility model provides the following technical solution: A bracket for mechanical processing includes a bracket body and two rollers connected to the top of the bracket body. A U-shaped plate is fixedly connected to the top surface of the top plate of the bracket body. The bottom plates of the two rollers are slidably connected to the top surface of the U-shaped plate. A chute is opened on the U-shaped plate. A fixing plate fixedly connected to the roller bottom plate is slidably connected in the chute. A wedge block is slidably connected between the two fixing plates. The two inclined sides of the wedge block are in contact with the outer wall of the fixing plate. The bottom surface of the wedge block is slidably connected to the top surface of the top plate of the bracket body, and the top surface is slidably connected to the bottom surface of the U-shaped plate. And a limiting member is arranged on the top surface of the wedge block. A fastening member is connected inside the U-shaped plate at the bottom surface of the roller.

[0007] Further, the fastening member includes a lower threaded rod, the lower threaded rod is fixedly connected to the bottom surface of the roller bottom plate, and the outer side of one end of the lower threaded rod passing through the chute is threadedly connected with a lower threaded ring, and the top surface of the lower threaded ring is in contact with the bottom surface of the U-shaped plate.

[0008] Further, the limiting member includes an upper threaded rod. A moving groove is opened on the top surface of the wedge block. A moving block is slidably connected in the moving groove. The top surface of the moving block is fixedly connected to the bottom surface of the upper threaded rod. The outer side of one end of the upper threaded rod passing through the U-shaped plate is threadedly connected with an upper threaded ring, and the bottom surface of the upper threaded ring is in contact with the top of the U-shaped plate.

[0009] Further, a spring is fixedly connected to the outer wall of the fixed plate on the side away from the wedge block, and the other end of the spring is fixedly connected to the inner wall of the vertical plate of the U-shaped plate.

[0010] Further, a limiting rod is fixedly connected to the outer wall of the fixed plate. The limiting rod is arranged inside the spring, and the limiting rod penetrates through the vertical plate of the U-shaped plate and is slidably connected to it.

[0014] In the utility model, two rollers are arranged on the U-shaped plate and move by means of the fixed plate. When the distance between the two rollers needs to be adjusted, only the wedge block needs to be pushed or pulled, so that the two inclined sides of the wedge block push the two fixed plates, causing the two fixed plates to move to the two sides or approach each other. The two fixed plates will drive the two rollers to slide on the upper surface of the U-shaped plate, thereby realizing the approach and separation of the two rollers. With this setting, it is convenient for the rollers to move to the two sides or approach the middle at the same time. Compared with the traditional adjustment with multiple bolts, the adjustment efficiency is improved and the operation complexity is reduced. The structure is simple, the operation is convenient, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] As Figures 1 to 5 shown, a bracket for machining includes a bracket body 1 and two rollers 2 connected to the top of the bracket body 1. A U-shaped plate 3 is fixedly connected to the top surface of the top plate of the bracket body 1. The bottom plates of the two rollers 2 are slidably connected to the top surface of the U-shaped plate 3. A chute 31 is opened on the U-shaped plate 3. A fixing plate 7 fixedly connected to the bottom plate of the roller 2 is slidably connected in the chute 31. A wedge block 4 is slidably connected between the two fixing plates 7. The two inclined sides of the wedge block 4 are in contact with the outer walls of the fixing plates 7. The bottom surface of the wedge block 4 is slidably connected to the top surface of the top plate of the bracket body 1, and the top surface is slidably connected to the bottom surface of the U-shaped plate 3. And a limiting member is provided on the top surface of the wedge block 4, and a fastening member is connected inside the U-shaped plate 3 at the bottom surface of the roller 2.

[0024] As Figures 1 to 5 shown, when the bracket for machining in the present invention is in use, when a worker needs to adjust the distance between the two rollers 2, only the limiting member on the wedge block 4 and the fastening member at the bottom of the roller 2 need to be opened. Then, push or pull the wedge block 4 so that the two inclined sides of the wedge block 4 abut against the two fixing plates 7, so that the two fixing plates 7 are pushed or brought closer to both sides. The two fixing plates 7 will drive the two rollers 2 to slide on the upper surface of the U-shaped plate 3, thereby realizing the approach and separation of the two rollers 2;

[0025] By arranging the two rollers 2 on the U-shaped plate 3 and moving them by the fixing plate 7, when the distance between the two rollers 2 needs to be adjusted, only the wedge block 4 needs to be pushed or pulled so that the two inclined sides of the wedge block 4 push the two fixing plates 7, so that the two fixing plates 7 are pushed or brought closer to both sides. The two fixing plates 7 will drive the two rollers 2 to slide on the upper surface of the U-shaped plate 3, thereby realizing the approach and separation of the two rollers 2. With this setting, it is convenient for the rollers 2 to move towards both sides or approach each other in the middle at the same time. Compared with the traditional adjustment with multiple bolts, the adjustment efficiency is improved and the operation complexity is reduced.

[0026] As Figure 3 、 Figure 4 and Figure 6 shown, the fastening member includes a lower threaded rod 8. The lower threaded rod 8 is fixedly connected to the bottom surface of the bottom plate of the roller 2. The lower threaded rod 8 passes through the outer side of one end of the chute 31 and is threadedly connected with a lower threaded ring 9. The top surface of the lower threaded ring 9 abuts against the bottom surface of the U-shaped plate 3.

[0027] Specifically, when the position of the roller 2 needs to be fixed after adjustment, just rotate the lower threaded ring 9 to increase the friction between the lower threaded ring 9 and the U-shaped plate 3 and make them press tightly, so that the position of the roller 2 can be limited. Although the lower threaded ring 9 is threadedly connected and matched with the lower threaded rod 8 here, only one bolt needs to be rotated for each roller 2, reducing the rotation frequency.

[0028] As Figure 2 , Figure 4 and Figure 5 shown, the limiting member includes an upper threaded rod 6. A moving groove 41 is formed in the top surface of the wedge-shaped block 4. A moving block 61 is slidably connected in the moving groove 41. The top surface of the moving block 61 is fixedly connected to the bottom surface of the upper threaded rod 6. The top surface of the upper threaded rod 6 penetrates through the outside of one end of the U-shaped plate 3 and is threadedly connected with an upper threaded ring 10. The bottom surface of the upper threaded ring 10 abuts against the top of the U-shaped plate 3.

[0029] Specifically, when the wedge-shaped block 4 slides in the U-shaped plate 3, the moving groove 41 on the top surface of the wedge-shaped block 4 will move outside the moving block 61. When the position of the wedge-shaped block 4 needs to be fixed, just rotate the upper threaded ring 10 to move the upper threaded rod 6 upward, increasing the friction between the top surface of the moving block 61 and the ground of the U-shaped plate 3, so that the friction between the moving block 61 in the moving groove 41 is increased, making the moving block 61 unable to move in the moving groove 41, and thus the position of the wedge-shaped block 4 can be fixed. This fixing method also only requires rotating one upper threaded ring 10 to achieve fixation, which is simple and convenient.

[0030] As Figure 3 , Figure 4 and Figure 6 shown, a spring 71 is fixedly connected to the outer wall of the fixed plate 7 on the side away from the wedge-shaped block 4. The other end of the spring 71 is fixedly connected to the inner wall of the vertical plate of the U-shaped plate 3.

[0031] Specifically, when the wedge-shaped block 4 moves, the spring 71 will give a certain force to the fixed plate 7 to prevent the fixed plate 7 from moving too much.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, a limiting rod 5 is fixedly connected to the outer wall of the fixed plate 7. The limiting rod 5 is arranged in the spring 71, and the limiting rod 5 penetrates through the vertical plate of the U-shaped plate 3 and is slidably connected thereto.

[0033] Specifically, when the spring 71 is squeezed, in order to prevent the spring 71 from deforming and bending, the limiting rod 5 can be used to prevent the spring 71 from deforming.

[0034] As Figure 3 , Figure 4 and Figure 6As shown, handles are fixedly connected to the outer walls of the upper threaded ring 10 and the lower threaded ring 9. The provision of the handles enables the rotation of the three bolts to be simpler and more convenient.

[0035] As Figure 5 shown, the cross-sections of the moving groove 41 and the moving block 61 are one of T-shaped or wedge-shaped. The T-shaped or wedge-shaped provision ensures that the moving block 61 does not disengage from the moving groove 41, and at the same time, the two options facilitate more choices for manufacturers.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
