Description

Technical Field

[0001] The utility model relates to a clamp, in particular to a clamp used for processing angle steel components, and belongs to the technical field of clamping tooling. Background Art

[0002] Angle steel components are commonly used in the manufacture of engineering machinery and equipment, such as standard fishplate sections for tower cranes. During the mass production of angle steel components, fixtures are required to secure the angle steel, and then various functional structures such as connecting plates, slots, and holes are welded onto them.

[0003] The commonly used fixtures currently used for processing angle steel components all have a flat plate to support the angle steel, and two sets of clamping assemblies are set on the flat plate to clamp the angle steel from opposite sides of the angle steel. The clamping assemblies generally use two telescopic cylinders to drive the clamping blocks to move toward and away from each other to achieve clamping and loosening of the angle steel. This fixture has the advantages of simple structure, low cost and easy implementation. However, the clamping assembly uses two telescopic cylinders to drive the clamping blocks to move toward and away from each other to achieve clamping and loosening of the angle steel, which cannot effectively clamp the edge of the angle steel. There are problems that the angle steel is easy to deform and the clamping reliability is low. In addition, the two telescopic cylinders are set on both sides to move toward and away from each other, and the installation space requires at least twice the telescopic stroke of the telescopic cylinder plus the space required for clamping and loosening the angle steel, resulting in a larger space occupied by the fixture as a whole.

[0006] Preferably, the base of the utility model is also equipped with a positioning assembly for positioning the angle steel in the length direction of the angle steel. The positioning assembly includes a push-out member and a positioning block installed on the base for abutting against one end of the angle steel.

[0010] Preferably, the clamping drive member and the pushing drive member of the present invention are both telescopic drive members.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] Example

[0021] See also Figures 1 to 5 The fixture for processing angle steel components in this embodiment includes a base 1 and one or more clamping components installed on the base 1 for clamping and fixing the angle steel. The base 1 is provided with a support component for contacting the inner side surfaces of the two edges of the angle steel and supporting the angle steel. The clamping component includes two clamping members 2 for respectively contacting the outer side surfaces of the two edges of the angle steel and cooperating with the support component for clamping. Each clamping member 2 is respectively connected to a clamping driving member 3 for driving the clamping member 2 to reciprocate along a set direction to clamp and release the corresponding edge. The set direction is a direction perpendicular to the outer side surfaces of the two edges of the angle steel.

[0022] This embodiment uses a support assembly to contact the inner side surfaces of the two sides of the angle steel and support the angle steel. The clamping drive 3 drives the clamping member 2 to reciprocate perpendicular to the outer side surfaces of the two sides of the angle steel to clamp and release the corresponding sides. That is, the support assembly and the clamping member 2 directly clamp the angle steel from the inner and outer sides of each side respectively. The angle steel will not be deformed, which can improve the reliability of clamping and reduce the space required for the clamping drive 3 to drive the clamping member 2 to move in the directions on both sides of the angle steel, thereby reducing the overall space occupied by the fixture and improving the compactness of the structure.

[0023] The base 1 in this embodiment is also equipped with a positioning assembly for positioning the angle steel in the longitudinal direction of the angle steel. The positioning assembly includes a push-out member 4 installed on the base 1 for contacting a positioning block 5 at one end of the angle steel. The push-out member 4 is connected to a push-out drive member 6 for driving the clamping member 2 toward and away from the positioning block 5. The positioning assembly can control the position of the angle steel in the longitudinal direction of the angle steel, thereby ensuring the accurate position of the angle steel. In addition, the positioning assembly adopts a structural form in which the positioning block 5 and the push-out drive member 6 drive the clamping member 2 toward and away from the positioning block 5. When the clamping member 2 approaches the positioning block 5, it can push the angle steel against the positioning block 5, thereby determining the position of the angle steel in the longitudinal direction of the angle steel. After the push-out is in place, the push-out drive member 6 drives the clamping member 2 away from the positioning block 5, and the angle steel is clamped and fixed by the clamping assembly. At this time, the clamping member 2 is also away from the end of the angle steel, providing a processing avoidance space, which facilitates the use of equipment to perform processing operations on the end of the angle steel.

[0024] The support assembly in this embodiment includes two or more support members 7 that are sequentially spaced apart along a straight line, thereby achieving the goals of simple structure and low cost while ensuring stable and reliable support.

[0025] like Figure 2 and Figure 3As shown, the support member 7 in this embodiment is a roller that can support the angle steel to move along the length direction of the angle steel, so as to facilitate the angle steel to move along the length direction of the angle steel to adjust its position.

[0026] The roller in this embodiment has two tapered surfaces 71 that are in surface contact with the inner side surfaces of the two sides of the angle steel, which can improve the support stability and reduce the possibility of deformation of the angle steel.

[0027] The clamping drive member 3 and the ejecting drive member 6 in this embodiment are telescopic drive members, which can be telescopic air cylinders, telescopic oil cylinders, electric push rods, etc.

[0028] The positioning block 5 in this embodiment is detachably mounted on the base 1 , which facilitates replacement of positioning blocks 5 of different thicknesses and shapes to meet the clamping requirements of angle steels at different positions, thereby improving applicability.

[0029] Through the above description, those skilled in the art can already implement it.
