Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to the technical field of jacquard shedding equipment. Background Art

[0002] The common cam jacquard machine box setting form on the market is to set an open box on the wall panel, and combine it with the cover plate to form a closed box. Its structural form can be found in the following two patent application publications CN105483895A and CN117364324A. Specifically, bearing mounting holes are respectively set on the wall panel and the cover plate, and the bearings at both ends of the camshaft are supported on the wall panel and the cover plate respectively. Since there is lubricating oil in the box formed by the wall panel and the cover plate, the wall panel and the cover plate are installed in an end-face contact manner, and the relative position depends on the positioning of the pin holes respectively set on the wall panel and the cover plate.

[0003] In view of the above, there are processing errors between the bearing hole on the wall panel and its pin hole and between the bearing hole on the cover plate and its pin hole, and there are also assembly errors in the pin assembly. The accumulated errors will cause a large coaxial error between the bearing hole on the wall panel and the bearing hole on the cover plate, thereby affecting the structural stability and strength of the entire box.

[0022] The utility model is described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] A cam box base structure of a cam jacquard machine includes a wall panel 1 and a cover plate 2 mounted on the wall panel 1. The wall panel 1 is protruded along one side where the cover plate 2 is installed to form a semi-enclosed box structure 13. The wall panel 1 and the semi-enclosed box structure 13 are both made of cast iron and are an integral structure formed in one piece.

[0025] The portion of the wall panel 1 covered by the semi-enclosed box structure 13 is defined as the bottom surface 13a of the semi-enclosed box structure 13 in this embodiment, and the side of the semi-enclosed box structure 13 combined with the cover plate 2 is used as the cover plate mounting surface 13b of the semi-enclosed box structure 13 in this embodiment. The bottom surface 13a and the cover plate mounting surface 13b are arranged facing each other in space and parallel to each other, and the cover plate 2 is assembled on the cover plate mounting surface 13b of the semi-enclosed box structure 13.

[0026] A bearing hole 11 is provided on the bottom surface 13a of the semi-enclosed box structure 13, and a cover mounting hole 12 is provided on the cover mounting surface 13b of the semi-enclosed box structure; the bearing hole 11 and the cover mounting hole 12 are coaxial holes formed by one-time clamping processing, and the cover mounting hole 12 is circular.

[0027] The cover plate 2 is assembled on the cover plate mounting surface 13b of the semi-enclosed box structure 13 through a connector. An outer cylindrical mating surface 22 is formed on the cover plate 2. The outer cylindrical mating surface 22 is adapted to be inserted into the cover plate mounting hole 12, and there is a transition fit between the two. The cover plate 2 is provided with a second bearing hole 21. The second bearing hole 21 is coaxial with the first bearing hole 11 on the wall panel 1 and has the same aperture. The second bearing hole 21 and the outer cylindrical mating surface 22 are coaxial structures formed by one-time clamping processing. The corresponding connecting parts of the cover plate mounting surface 13b and the cover plate 2 are provided with connecting screw holes 3 for connecting bolts to fix the two.

[0028] The cam box base structure of a cam jacquard machine in this embodiment, the structural design and assembly connection process are as follows:

[0029] The wall panel and cover plate are cast from grey cast iron blanks and processed step by step according to the processing technology. To ensure the coaxial accuracy of the bearing hole of the wall panel and the mounting hole of the cover plate, the two holes need to be clamped and processed at one time; the bearing hole and the outer cylindrical surface of the cover plate are also processed by clamping at one time. The assembled camshaft part is installed inside the box of the wall panel, and then the cover plate is installed on the wall panel to form a closed box. To prevent oil leakage, necessary sealing measures are used between the cover plate and the wall panel.
