Description

Technical Field

[0001] The utility model relates to the technical field of rectangular frame clamps, in particular to a clamp for welding a rectangular frame. Background Art

[0002] During the welding process of the rectangular frame, the four frame plates to be welded need to be fixed first. The four frame plates are in contact with each other and enclose a rectangular space. During the process of fixing the four frame plates, it is necessary to ensure that the width of the weld formed between two adjacent frame plates is stable.

[0003] During the welding process of the existing rectangular frame, a clamp is often required to stably clamp the four frame plates. However, the clamp used for the rectangular frame plates is often a clamp for a fixed size. Therefore, when the size of the rectangular frame to be produced changes, the clamp used also needs to be replaced accordingly. Based on the above situation, a clamp for rectangular frame welding needs to be designed to solve the above problem. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0025] Reference Figure 1-Figure 5 , a rectangular frame welding fixture, comprising

[0026] A slide rail group, wherein the number of the slide rail groups is two, and the two slide rail groups are arranged perpendicular to each other on the workbench 1 on a horizontal projection plane;

[0027] A sliding block 3, wherein the sliding block 3 is slidably connected to the slide rail group, and each of the slide rail groups is provided with two sliding blocks 3;

[0028] A positioning member, which is arranged on the sliding block 3 and is used to lock the sliding block 3 on the slide rail assembly;

[0029] The clamping assembly 6 is installed on the sliding block 3 and is used to clamp the frame plate 7 to be welded on the sliding block 3 .

[0030] The main inventive point of the utility model is that a clamping assembly 6 capable of clamping a frame plate 7 is arranged on a sliding block 3, and the sliding block 3 can be moved by a slide rail group and a positioning member, so that rectangular frames of different sizes can be clamped stably.

[0031] Specifically, the positioning member can be a positioning bolt 5 including a vertical thread penetrating the sliding block 3. When the sliding block 3 needs to be locked on the slide rail group, the positioning bolt 5 is rotated until its bottom is tightly pressed against the workbench 1 to achieve locking. When the bottom of the positioning bolt 5 is tightly pressed against the surface of the workbench 1, the pressure between the sliding block 3 and the slide rail group increases, and the static friction between the two also increases, so that the sliding block 3 is stabilized on the slide rail group. The positioning bolt 5 is rotated in the opposite direction so that the bottom of the positioning bolt 5 is disengaged from the surface of the workbench 1, thereby relieving the pressure between the sliding block 3 and the slide rail group. At this time, the sliding block 3 can move smoothly on the slide rail group. By setting the positioning member formed by the positioning bolt 5, the sliding block 3 can be locked at any position of the slide rail group.

[0032] Specifically, the clamping assembly 6 can include a fixed clamping plate 601 fixed at the end of the sliding block 3, a movable clamping plate 602 that can move along the surface of the sliding block 3, a guide rod 603 fixedly connected to the fixed clamping plate 601 and slidingly passing through the movable clamping plate 602, a boss 605 formed at the end of the guide rod 603, and a spring 604 that is sleeved on the outer surface of the guide rod 603 and is between the boss 605 and the movable clamping plate 602.

[0033] By setting up a clamping assembly 6 consisting of a movable clamp 602, a fixed clamp 601, a guide rod 603 and a spring 604, the frame plate 7 can be stably clamped by the movable clamp 602 and the fixed clamp 601. The clamping force between the two is achieved by compressing the spring 604. At the same time, the spring 604 is used to provide the clamping force, and the distance between the movable clamp 602 and the fixed clamp 601 can be adjusted to achieve clamping of frame plates 7 of different widths.

[0034] Specifically, the slide rail assembly may include two slide rail rods 2 in an inverted U shape, and the sliding block 3 is provided with through holes through which the two slide rail rods 2 can pass.

[0035] By providing a slide rail group consisting of two slide rail rods 2, the slide block 3 can slide smoothly on the slide rail group, and the slide block 3 is provided with a through hole for the slide rail rod 2 to pass through, so that the slide block 3 can slide smoothly.

[0036] Specifically, the two slide rail groups are staggered in the height direction, the upper surfaces of the sliding blocks 3 on the two slide rail groups are coplanar, and the upper surface of the slide rail rod 2 is provided with scale lines 4.

[0037] The two slide rail groups are staggered in the height direction, and the upper surfaces of the sliding blocks 3 on the two slide rail groups are coplanar, which can prevent the scales of the slide rail rods 2 on the two slide rail groups from affecting each other. At the same time, the four clamped frame plates 7 can be stably clamped in the same plane. The scale lines 4 can assist in more accurate positioning of the sliding blocks 3 on the slide rail groups, ensuring that the welds 701 formed between the four frame plates 7 are smoother.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
