Description

Technical Field

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

[0002] During the processing of steel structures, such as drilling and polishing, it is necessary to use fixtures to hold the steel structure to ensure stability during processing. Current fixtures mainly rely on friction to hold hollow steel structures from the outside. This processing method applies a large force to the surface of the steel structure, which can easily damage the outer surface of the steel structure. Therefore, it is necessary to design a steel structure processing fixture. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel structure processing fixture to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a steel structure processing fixture, including a fixture body, the fixture body including a base, a static fixing plate fixedly installed at a first end along the length direction of the base, and a movable fixing plate installed at a second end via a cylinder, clamping assemblies provided on the sides of the static fixing plate and the movable fixing plate that are close to each other, the clamping assemblies including static clamping plates fixedly installed on the sides of the static fixing plate and the movable fixing plate that are close to each other, and mounting plates fixedly installed on the sides of the static fixing plate and the movable fixing plate that are far from each other, a lead screw mounted on the top of the mounting plate via a bearing, and a movable seat mounted on the outside of the lead screw via a thread, the static fixing plate... Both the fixed plate and the movable fixed plate have through slots on their adjacent sides. The movable seat is slidably installed inside the through slots. A movable clamp is fixedly installed on the adjacent side of the movable seat. The movable clamp is located at the bottom of the fixed clamp and is parallel to the fixed clamp. It also includes a support assembly located at the center of the top of the base. The open ends of the steel structure are inserted into the outside of the fixed clamp and the movable clamp on the fixed plate and the movable fixed plate, respectively. By rotating the drive screw, the fixed clamp and the movable clamp press and limit the upper and lower ends of the inner wall of the steel structure. This fixing method avoids the possibility of external damage caused by external positioning and clamping.

[0005] Furthermore, each of the moving and stationary clamping plates is equipped with a clamping plate at its far end, and the corners of the insertion end of the clamping plate are designed with rounded chamfers to facilitate the connection of the steel structure.

[0006] Furthermore, the clamping plate is detachably connected to the stationary clamping plate and the moving clamping plate respectively by screws, which is convenient for the shape of the steel structure. The moving clamping plate or the stationary clamping plate can be connected by screws in either a flat or arc shape.

[0007] Furthermore, a stabilizing plate is fixedly installed at the bottom end of the movable fixed plate, and the stabilizing plate and the top end of the base slide against each other to increase the stability of the movable fixed plate's movement.

[0008] Furthermore, the support assembly includes an electric telescopic rod located at the top of the base. The telescopic end of the electric telescopic rod is equipped with a support plate. Through the operation of the electric telescopic rod, the support plate and the bottom of the steel structure are supported, thereby increasing the stability of the steel structure support.

[0009] Furthermore, a groove is provided at the top of the base along the movement direction of the movable fixed plate, and a slider is slidably installed inside the groove. The top of the slider is connected to the bottom of the electric telescopic rod, which facilitates the adjustment of the position of the electric telescopic rod at the top of the base and the adjustment of the support position for the steel structure.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model adopts a design in which the openings at both ends of the steel structure are respectively inserted into the outside of the static clamping plate and the moving clamping plate on the static fixed plate and the moving fixed plate. By driving the lead screw to rotate, the static clamping plate and the moving clamping plate press and limit the upper and lower ends of the inner wall of the steel structure. This fixing method avoids the situation that external positioning and clamping can easily lead to external damage.

[0012] 2. This utility model adopts this design so that after the steel structure is fixed, the electric telescopic rod is driven to extend, causing the support plate to move upward until the support plate supports the bottom of the steel structure, thus increasing the stability during fixing.

Clamping assemblies 200 are provided on the sides of the static fixing plate 111 and the movable fixing plate 113 that are close to each other. Each clamping assembly 200 includes a static clamping piece 210 fixedly installed on the side of the static fixing plate 111 and the movable fixing plate 113 that are close to each other. Mounting plates 211 are fixedly installed on the sides of the static fixing plate 111 and the movable fixing plate 113 that are far apart from each other. A lead screw 212 is mounted on the top of the mounting plate 211 via a bearing, and a movable seat 213 is threaded onto the outside of the lead screw 212. The static fixing plate 111... A through slot 214 is provided on the side of the movable fixing plate 113 that is close to each other. The movable seat 213 is slidably installed inside the through slot 214. A movable clamping plate 215 is fixedly installed on the side of the movable seat 213 that is close to each other. The movable clamping plate 215 is located at the bottom of the stationary clamping plate 210 and is parallel to the stationary clamping plate 210. A support component 300 is also provided at the center of the top of the base 110. A clamping plate 216 is installed on the side of the movable clamping plate 215 and the stationary clamping plate 210 that are far from each other. The corners of the insertion end of the clamping plate 216 are all designed with rounded chamfers. The clamping plate 216 is detachably connected to the stationary clamping plate 210 and the movable clamping plate 215 respectively by screws. A stabilizing plate 114 is fixedly installed on the bottom of the movable fixing plate 113. The stabilizing plate 114 and the top of the base 110 are slidably attached.

[0019] The working principle of Embodiment 1 of this utility model is as follows: In use, the open end of the steel structure is aligned with the outside of the movable clamping piece 215 and the stationary clamping piece 210 on the stationary fixed plate 111 and the movable fixed plate 113, and then inserted. After insertion, the screw 212 is rotated to make the movable clamping piece 215 move away from the stationary clamping piece 210 until the stationary clamping piece 210 and the movable clamping piece 215 support the inner wall of the steel structure, thereby restricting and fixing the end of the steel structure. By driving the cylinder 112, the distance between the movable fixed plate 113 and the stationary fixed plate 111 can be adjusted to accommodate steel structures of different lengths. Then, the positioned steel structure is processed by equipment such as an angle grinder.

[0020] Example 2:

[0021] The difference between Embodiment 2 and Embodiment 1 is that the support assembly 300 includes an electric telescopic rod 312 located at the top of the base 110.

A support plate 313 is installed at the telescopic end of the electric telescopic rod 312. A groove 310 is provided at the top of the base 110 along the movement direction of the movable fixed plate 113. A slider 311 is slidably installed inside the groove 310. The top of the slider 311 is connected to the bottom of the electric telescopic rod 312. After the steel structure is fixed, the electric telescopic rod 312 is driven to extend, causing the support plate 313 to move upward until the support plate 313 supports the bottom of the steel structure, increasing the stability during fixing.
