Description

Technical Field

[0001] This utility model belongs to the field of steel bar processing technology, and specifically relates to a steel bar processing clamping structure. Background Technology

[0002] In the field of steel bar processing, the stability and flexibility of the clamping structure are key factors in ensuring processing accuracy and efficiency. Most existing clamping structures adopt a fixed clamping method, that is, clamping the steel bar with a clamp. In actual operation, this clamping structure requires corresponding adjustments according to the steel bar of different sizes, which is time-consuming and labor-intensive. At the same time, after the steel bar is processed, the clamp needs to be disassembled again to remove the steel bar. This not only increases the complexity of operation, but also reduces the processing efficiency. Therefore, this utility model proposes a clamping structure for steel bar processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1 to 3 This is an embodiment of the present utility model, which provides a technical solution: a steel bar processing clamping structure, including...

[0021] Two cylindrical bases 1 are welded and fixed to the top of the processing table 6. A top base block 2 is rotatably installed on the top of the cylindrical base 1. A telescopic column 3 is movably installed at the end of the top base block 2. A clamping block 4 is fixed to the front end of the telescopic column 3. The steel rod 7 is clamped between the two symmetrical clamping blocks 4. Under the clamping action of the two clamping blocks 4, the steel rod 7 can be effectively clamped, which makes it convenient for subsequent operators to process the surface of the steel rod 7, such as sandblasting, spraying, etc.

[0022] The top base block 2 has an inner sliding groove 22 inside, and a spring 23 and an inner slider 24 are installed inside the inner sliding groove 22. The rear end of the telescopic column 3 passes through the inner sliding groove 22 and is fixed to the inner slider 24. Under the pushing of the spring 23, the clamping block 4 can stably clamp the steel rod 7 during daily use.

[0023] A rotation limiting structure is also provided between the top base block 2 and the cylindrical base 1.

[0024] In this embodiment, preferably, an anti-slip inner pad 41 is glued to the inner surface of the clamping block 4. The anti-slip inner pad 41 is made of rubber and is pressed into contact with the steel rod 7. This can further improve the clamping stability of the clamping block 4 on the steel rod 7, play a certain anti-slip role, and prevent the steel rod 7 from rotating during subsequent clamping and processing.

[0025] In this embodiment, preferably, a cylindrical mounting groove is formed on the inner wall of one end of the inner slide groove 22, one end of the spring 23 is installed in the cylindrical mounting groove, and the other end of the spring 23 is in close contact with the inner slider 24. The cylindrical mounting groove can ensure the installation stability of the spring 23 and prevent the spring 23 from deviating.

[0026] In this embodiment, preferably, a shaft block 5 is fixed on the top surface of the cylindrical base 1, and the top base block 2 is rotatably sleeved on the shaft block 5, so that the top base block 2 can rotate on the top of the cylindrical base 1. When the steel rod 7 is processed later and needs to be removed, the operator does not need to disassemble this clamping structure. He only needs to push the clamping block 4 towards the top base block 2, so that the telescopic column 3 pushes the inner slider 24 and the spring 23 is gradually compressed, causing the clamping block 4 to move away from the steel rod 7. Then, the top base block 2 is rotated, and the clamping block 4 can be rotated and moved away directly without obstructing the steel rod 7. At this time, the steel rod 7 can be quickly removed, improving the convenience of picking up and putting down.

[0027] In this embodiment, preferably, the rotation limiting structure includes a rubber positioning seat 21 glued to the bottom surface of the top base block 2, multiple positioning protrusions 11 provided on the surface of the cylindrical base 1, and positioning holes 25 opened on the surface of the rubber positioning seat 21 and corresponding to the positioning protrusions 11. One of the positioning protrusions 11 is inserted into the positioning hole 25 for limiting the top base block 2 during daily use, so that the top base block 2 will not easily rotate. The rubber positioning seat 21 is made of rubber material and will undergo elastic deformation when squeezed. When it is necessary to rotate the top base block 2, the top base block 2 can be pushed forcefully, so that the rubber positioning seat 21 is squeezed by the positioning protrusions 11 and undergoes elastic deformation, so that the positioning protrusions 11 in the initial position are squeezed out of the positioning hole 25, realizing the smooth rotation of the top base block 2. As the top base block 2 rotates, other positioning protrusions 11 will be squeezed into the positioning hole 25 to achieve auxiliary limiting after the top base block 2 rotates.

[0028] In this embodiment, preferably, the cross-section of the rubber positioning seat 21 is L-shaped, the top of the rubber positioning seat 21 is fixed to the bottom surface of the top base block 2, and the bottom side of the rubber positioning seat 21 is in sliding contact with the cylindrical base 1.

[0029] In this embodiment, preferably, the end surface of the top base block 2 is provided with a through hole for the telescopic column 3 to pass through, and the through hole is connected to the inner sliding groove 22.

[0030] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
