Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically a seamless steel pipe feeding clamp. Background Technology

[0002] Seamless steel pipe feeding fixtures are tools used to assist in feeding seamless steel pipes during processing. They are mainly used to fix and clamp seamless steel pipes to ensure their stability and accuracy during processing.

[0003] Patent CN210557905U discloses a seamless steel pipe feeding clamp, which includes a base, a fixed plate fixedly installed on the top of the base, a fixed rod fixedly installed on the bottom left end of the fixed plate, a groove provided on the right end of the fixed plate, a rectangular opening on the top wall of the groove, and an internal threaded ring fixedly installed on the right end of the inner side wall of the groove. The device completes the limiting operation of another clamping ring by providing a groove on the right end of the fixed plate, a rectangular opening on the top wall of the groove, a screw in the groove, and a cylindrical block installed on the left end of the screw. A slider is connected to the cylindrical block through a rotating part. Compared with the traditional two-rod limiting method, it is simpler, has a simpler structure, is easy to install, and has a lower cost.

[0004] However, the existing device directly places the seamless steel pipe to be processed between two clamping rings and uses a motor, crossbar, and other structures to clamp and limit the steel pipe. Due to the presence of the rubber layer, the relative position of the steel pipe and the clamping rings cannot be adjusted after the steel pipe is clamped, thus making it impossible to adjust and process the seamless steel pipe. To address this issue, a seamless steel pipe feeding fixture is proposed to solve the problem that existing feeding fixtures are difficult to adjust according to processing requirements after use.

[0015] (III) Beneficial Effects

[0016] 1. This seamless steel pipe feeding fixture places the seamless steel pipe to be clamped and limited in the U-shaped clamping seat. Then, the hydraulic telescopic column is activated to drive the control plate in the U-shaped linkage frame to rotate clockwise and compress the left U-shaped limiting frame. This, in turn, drives the arc-shaped clamping block along with the first ball bearing to clamp and limit the steel pipe. At this time, the position of the steel pipe can be adjusted. Then, the control plate is rotated in the opposite direction. With the help of the spring, the left arc-shaped clamping block is reset, and the right arc-shaped clamping block drives the anti-slip pad to stably clamp and limit the steel pipe. This solves the problem that existing feeding fixtures are difficult to adjust the steel pipe itself according to processing requirements after use.

[0017] 2. This seamless steel pipe feeding fixture, based on the length of the steel pipe, adjusts the position of the support seat by cooperating with the T-shaped slider in the T-shaped groove, and then tightens the limiting bolt on the limiting block to fix the position of the support seat in conjunction with the limiting groove. Then, the steel pipe is placed on the third ball in the support arc groove, and then the electric telescopic rod is activated to drive the top support seat to move down, which can further clamp and limit the steel pipe. At the same time, the third ball does not affect the adjustment of the steel pipe, thus improving the stability of the steel pipe during the use of this seamless steel pipe feeding fixture.

[0025] Furthermore, the two ends of the spring 5 are fixedly connected to the U-shaped linkage frame 4 and the U-shaped clamp 2 respectively. When the arc-shaped clamp 3 is in the initial position, the spring 5 is in the normal state.

[0026] Furthermore, both ends of the hydraulic telescopic column 8 are rotatably connected to the U-shaped clamp 2 and the control plate 7.

[0027] Furthermore, when the arc-shaped clamping block 3 is in the initial position, the control plate 7 is in contact with the surface of the U-shaped linkage frame 4, and the surface of the control plate 7 facing the U-shaped linkage frame 4 is smooth.

[0028] Furthermore, the support mechanism 13 includes two support seats 131 symmetrically arranged on the top of the fixture table 1. The top of the bottom support seat 131 is provided with a support arc groove 132. The inner cavity of the support arc groove 132 is rotatably provided with a third ball 133. The inner wall of the bottom support seat 131 is symmetrically provided with an electric telescopic rod 139. The top of the bottommost third ball 133 and the top of the second ball 11 are located on the same horizontal plane.

[0029] Furthermore, the top of the fixture table 1 is symmetrically provided with T-shaped grooves 134, and T-shaped sliders 135 are slidably arranged in the inner cavity of the T-shaped grooves 134. The T-shaped sliders 135 are fixedly connected to the support base 131, and the top of the electric telescopic rod 139 is fixedly connected to the upper support base 131.

[0030] Furthermore, the two ends of the support base 131 are fixedly connected to limit blocks 136, and the top of the clamping table 1 is symmetrically provided with limit grooves 138. The top of the limit block 136 is threaded through and screwed with a limit bolt 137. The bottom of the limit bolt 137 extends into the inner cavity of the limit groove 138.

Then, the limit bolt 137 on the limit block 136 is tightened to fix the position of the support base 131 in conjunction with the limit groove 138. Then, the steel pipe is placed on the third ball 133 in the support arc groove 132. Then, the electric telescopic rod 139 is turned on to drive the top support base 131 to move down, which can further clamp and limit the steel pipe. At the same time, the adjustment of the steel pipe is not affected by the third ball 133, thus improving the stability of the steel pipe during the use of this seamless steel pipe feeding clamp.

[0031] Working principle: When using this seamless steel pipe feeding fixture, after placing the seamless steel pipe to be clamped and limited in the U-shaped clamp 2, the hydraulic telescopic column 8 is activated, which drives the control plate 7 in the U-shaped linkage frame 4 to rotate clockwise and compress the left U-shaped limiting frame 6. This, in turn, drives the arc-shaped clamping block 3 together with the first ball bearing 9 to clamp and limit the steel pipe. At this time, the position of the steel pipe can be adjusted. Then, the control plate 7 is rotated in the opposite direction. With the help of the spring 5, the left arc-shaped clamping block 3 is reset, and the right arc-shaped clamping block 3 drives the anti-slip pad 10 to stably clamp and limit the steel pipe. This solves the problem that existing feeding fixtures are difficult to adjust the steel pipe itself according to processing requirements after use. When the seamless steel pipe is placed in the U-shaped clamp 2 and clamped and limited by the arc-shaped clamping block 3 with the first ball bearing 9, the lateral position or angle of the steel pipe can be adjusted while limiting the steel pipe, thus improving the practicality of this seamless steel pipe feeding fixture.
