Description

Technical Field

[0001] The utility model relates to the technical field of hangers, in particular to a hook-type workpiece rack for a shot blasting machine. Background Art

[0002] The hook-type shot blasting machine is a kind of equipment used for surface treatment. The workpiece is suspended in the cleaning chamber by a hook and a workpiece rack. At the same time, the strong shot blasting flow generated by the high-speed shot blasting wheel is used to clean, remove rust, deoxidize, increase the roughness of the workpiece surface, etc.

[0003] In the prior art, most workpiece racks are welded in a fixed structure, which is suitable for processing workpieces with regular shapes, relatively uniform sizes and low surface treatment requirements. However, in some special application scenarios or when the workpiece surface quality requirements are high, the angle of the workpiece rack needs to be adjusted to ensure comprehensive and uniform cleaning of the workpiece surface.

[0004] Therefore, in order to solve the defect that most workpiece racks have fixed structures and cannot adjust the angle, it is necessary to propose a workpiece rack for a hook-type shot blasting machine. Utility Model Content

[0005] The purpose of the utility model is to provide a workpiece rack for a hook-type shot blasting machine. By rotating the movable bracket, the angle of the workpiece hoisted at its lower end can be adjusted, so that the coverage of the shot blasting flow on the surface of the workpiece is more uniform, avoiding missed or excessive shot blasting, improving the uniformity and integrity of shot blasting cleaning, and solving the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A workpiece frame for a hook-type shot blasting machine, comprising a main frame and a movable bracket hinged to the side end of the main frame, positioning plates are symmetrically welded at the left and right ends of the main frame, a movable groove is opened on the positioning plate, and a plurality of adjustment holes are equidistantly opened at the position of the positioning plate located at the upper end of the movable groove;

[0008] The movable bracket is hinged at the lower end of the positioning plate, a movable plate is welded on the upper surface of the movable bracket, the movable plate is fixedly connected to the limit plate through a movable rod, the movable rod is movably arranged in the movable groove, and the limit plate is fixedly connected to the positioning plate through a positioning pin.

[0009] Preferably, a lifting ring is welded on the top of the main frame.

[0010] Preferably, a hanging plate is welded to the lower surface of the movable bracket, and a plurality of hanging hook holes are equidistantly provided on the hanging plate.

[0011] Preferably, the positioning plate, the movable groove and the movable plate are all arranged in an arc shape.

[0012] Preferably, the positioning pin is detachably connected to the limiting plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The workpiece rack of the hook-type shot blasting machine rotates the movable bracket to make the movable rod slide in the movable groove and drive the limit plate to rotate until it is rotated to the required angle, and then the limit plate and the positioning plate are fixedly connected by the positioning pin, thereby fixing the entire movable bracket. The shot of the shot blasting machine is generally projected at the upper end and the side end inside the shot blasting machine. When the shot at the side end is projected onto the surface of the workpiece, the angle of the bracket is adjusted to make the shot blasting flow contact with the surface of the workpiece more widely, improve the uniformity of the shot material covering the workpiece surface, avoid missed or excessive projection, and ensure that the workpiece surface is fully cleaned.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] To solve the technical problem of how to adjust the angle of the workpiece holder, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0021] A workpiece rack for a hook-type shot blasting machine includes a main frame 1 and a movable bracket 2 hinged to the side end of the main frame 1, positioning plates 12 are symmetrically welded on the left and right ends of the main frame 1, and a movable groove 122 is opened on the positioning plate 12. The positioning plate 12 is located at the upper end of the movable groove 122 and has multiple adjustment holes 121 equidistantly opened.

[0022] The movable bracket 2 is hinged to the lower end of the positioning plate 12, and a movable plate 23 is welded on the upper surface of the movable bracket 2. The movable plate 23 is fixedly connected to the limit plate 25 through a movable rod 24. The movable rod 24 is movably arranged in the movable groove 122. The limit plate 25 is fixedly connected to the positioning plate 12 through a positioning pin 26, and the positioning pin 26 is detachably connected to the limit plate 25.

[0023] The positioning plate 12 , the movable groove 122 and the movable plate 23 are all arranged in an arc shape.

[0024] Specifically, when it is necessary to adjust the angle of the movable bracket 2, the positioning pin 26 on the limit plate 25 is removed, and then the movable bracket 2 is rotated. The movable bracket 2 drives the movable plate 23 fixed thereto to rotate. At this time, the movable rod 24 moves in the movable groove 122 and drives the limit plate 25 to rotate until it is rotated to the desired angle. The positioning pin 26 is inserted into the corresponding adjustment hole 121 to fix the limit plate 25, so that the movable bracket 2 is fixed, thereby realizing the adjustment of the angle of the movable bracket 2.

[0025] In order to solve the technical problem of how to hoist the workpiece on the workpiece rack, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0026] A lifting ring 11 is welded to the top of the main frame 1 , a lifting plate 21 is welded to the lower surface of the movable bracket 2 , and a plurality of lifting hook holes 22 are equidistantly provided on the lifting plate 21 .

[0027] Specifically, the workpiece is lifted by a hook, and the other end of the hook is hung in the hook hole 22, and finally the main frame 1 is hung in the cleaning chamber of the shot blasting machine through the lifting ring 11 to realize the lifting of the workpiece.

[0028] Working principle: When using the workpiece rack for the hook-type shot blasting machine, first connect the workpiece rack to the hook of the shot blasting machine through the lifting ring 11, then adjust the angle of the movable bracket 2 according to the size of the workpiece, remove the positioning pin 26 on the limit plate 25, and rotate the movable bracket 2. The movable bracket 2 drives the movable plate 23 fixed thereto to rotate, so that the movable rod 24 moves in the movable groove 122, and the movable rod 24 drives the limit plate 25 fixed thereto to rotate until it reaches the required angle, insert the positioning pin 26 into the corresponding adjustment hole 121, fix the movable bracket 2, and finally hang the hook in the hook hole 22 in turn, and then hang the workpiece on the other end of the hook to realize the lifting of the workpiece.
