Description

Technical Field

[0001] This utility model relates to the field of positioning frame welding, and in particular to a positioning frame welding fixture. Background Technology

[0002] When welding the positioning frame, it is necessary to fix the positioning frame to prevent it from shifting during the welding process and causing welding deformation.

[0003] Therefore, it is necessary to design a welding fixture for a positioning frame that is easy to fix. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the positioning frame needs to be fixed during the welding process to prevent it from shifting and causing welding deformation.

[0005] To solve the above-mentioned technical problems, the present invention provides a positioning frame welding fixture, which includes a welding fixture table, a cylinder installed at the bottom of the welding fixture table, a clamping plate provided at the top of the welding fixture table, the clamping plate being fixedly connected to the output shaft of the cylinder, a plurality of bolt holes being opened on the surface of the welding fixture table, a pad being provided on the surface of the welding fixture table, the pad being at the same horizontal position as the clamping plate, and the pad being fixedly installed to the welding fixture table by bolts passing through the bolt holes.

[0006] A top block is fixedly installed on the welding fixture table by bolts passing through bolt holes. The top block is located at the left and right center positions of the welding fixture table, and a pad is fixedly installed on the top block.

[0007] Several pairs of transverse limiting blocks are fixedly installed on the welding fixture by bolts passing through bolt holes. Several pairs of longitudinal limiting blocks are also fixedly installed on the welding fixture by bolts passing through bolt holes.

[0008] A clamping block is installed at the lower part of the clamping plate.

[0009] The lower part of the welding fixture table is equipped with a storage platform.

[0010] The beneficial effects of this utility model are as follows:

[0011] Equipped with clamping plates, lateral limiting blocks, and longitudinal limiting blocks, the positioning frame to be welded is placed on the welding fixture, positioned on the pad below the clamping plates. Then, a controlled cylinder moves the clamping plates downwards, clamping and fixing the positioning frame for easy welding. When the positioning frame is placed on the pad, its center is on the pad, which provides excellent support and stability. The positions of the lateral and longitudinal limiting blocks are determined according to the size of the positioning frame, and bolts are used for fixing. When the pad is placed on the positioning frame, the horizontal and vertical directions of the positioning frame are limited by the horizontal and vertical limiting blocks to prevent movement during clamping or welding. The clamping blocks come in various specifications to fit different positioning frames. When the clamping plate moves downward to clamp the positioning frame, the matching clamping block contacts the positioning frame, making the clamping more stable. The storage platform is used to place clamping blocks of various specifications, making it easy to pick up and replace the clamping blocks. All cylinders of this fixture are installed at the bottom of the welding fixture table, which solves the problems of cylinders or mounting plates blocking the gun during welding and welding slag burning the air pipes or cylinders during welding.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] Please see Figure 1-3The welding fixture includes a welding fixture table 1, a cylinder 2 installed at the bottom of the welding fixture table 1, and a clamping plate 3 installed at the top of the welding fixture table 1. The clamping plate 3 is fixedly connected to the output shaft of the cylinder 2. Several bolt holes are opened on the surface of the welding fixture table 1, and a pad 4 is installed on the surface of the welding fixture table 1. The pad 4 is at the same horizontal position as the clamping plate 3. The pad 4 is fixedly installed to the welding fixture table 1 by bolts passing through the bolt holes. The positioning frame to be welded is placed on the welding fixture table 1, so that it is on the pad 4 below the clamping plate 3. Then, the cylinder 2 is controlled to drive the clamping plate 3 to move downward, so that the positioning frame can be clamped and fixed, which facilitates the welding of the positioning frame.

[0018] A top block 5 is fixedly installed on the welding fixture 1 by bolts passing through bolt holes. The top block 5 is located at the left and right center of the welding fixture 1. A pad 6 is fixedly installed on the top block 5. When the positioning frame to be welded is placed on the pad 4, its center is on the pad 6. The pad 6 can play a good supporting role, making the positioning frame more stable.

[0019] Several pairs of transverse limiting blocks 7 and several pairs of longitudinal limiting blocks 8 are fixedly installed on the welding fixture 1 by bolts passing through bolt holes. The positions of the transverse limiting blocks 7 and the longitudinal limiting blocks 8 are determined according to the different sizes of the positioning frame and fixed by bolts passing through bolt holes. When the pad block 4 is placed on the positioning frame, the transverse and longitudinal directions of the positioning frame will be limited by the transverse limiting blocks 7 and the longitudinal limiting blocks 8 to prevent movement during clamping or welding.

[0020] A clamping block 9 is installed at the lower part of the clamping plate 3. The clamping block 9 comes in various specifications to fit various positioning frames. When the clamping plate 3 moves downward to clamp the positioning frame, the matching clamping block 9 contacts the positioning frame, making the clamping more stable.

[0021] The lower part of the welding fixture table 1 is provided with a storage platform 10; the storage platform 10 is used to place clamps 9 of various specifications, so as to facilitate the removal and replacement of clamps 9.

[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
