[0001] The utility model relates to a novel positioning structure for riveting pulley combinations for electronic jacquard machine components, belonging to the technical field of electronic jacquard machine assembly. Background Art

[0002] The pulley assembly is a crucial component of an electronic jacquard machine. Its primary function is to control the movement of the jacquard machine, thereby enabling its various functions. By rotating and adjusting the pulleys, the pulley assembly enables various motion modes, thereby controlling the pattern and design of the fabric. The quality of the pulley assembly is directly related to the production efficiency and fabric quality of the electronic jacquard machine, thus highlighting its importance.

[0003] The positioning mechanism used in the existing pulley combination automatic riveting production line is positioned through the arc surface of the pulley bracket hole. However, under this positioning method, the equipment alarms frequently and the defective rate of the pulley combination products after riveting is high. Therefore, it is very necessary to develop a new positioning structure for the riveting of pulley combinations for electronic jacquard machine components. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a novel positioning structure for riveting pulley combinations for electronic jacquard machine components.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A new positioning structure for riveting a pulley combination for an electronic jacquard machine assembly includes a main body, a left positioning block and a right positioning block connected to the front side of the main body, the positions of the right positioning block and the left positioning block are adapted to the tops on both sides of the bearing pulley bracket hole, and the main body is provided with a mounting hole and a positioning hole.

[0007] The lower end surface of the body is provided with a lower mounting surface.

[0008] The lower mounting surface is a groove structure.

[0009] The left positioning block is L-shaped.

[0010] A cover plate is provided on the left positioning block.

[0011] The right positioning block is in the shape of a cuboid.

[0012] The body, the left positioning block and the right positioning block are integrally formed.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the setting of the new positioning structure greatly reduces the alarm frequency of the pulley assembly equipment during the assembly process, reduces the defective rate of the assembled pulley assembly products, has high work efficiency, and has good practicality and adaptability; by setting the left positioning block and the right positioning block, precise positioning is achieved on both sides of the bearing pulley bracket hole, avoiding the problem of frequent alarms of the equipment and a high defective rate of the assembled product when positioning with the arc surface of the bearing pulley bracket hole, thereby reducing the overall work efficiency.

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figure 1-Figure 3 As shown, a new positioning structure for riveting a pulley combination for an electronic jacquard machine assembly includes a main body 1, a left positioning block 2 and a right positioning block 3 are provided on the front side of the main body 1, and the positions of the right positioning block 3 and the left positioning block 2 are adapted to the tops on both sides of the bearing pulley bracket hole, and the main body 1 is provided with a mounting hole 4 and a positioning hole 5.

[0020] The lower end surface of the body 1 is provided with a lower mounting surface 6 .

[0021] The lower mounting surface 6 is a groove structure.

[0022] The left positioning block 2 is L-shaped.

[0023] A cover plate is provided on the left positioning block 2 .

[0024] The right positioning block 3 is in the shape of a cuboid.

[0025] The body 1 , the left positioning block 2 and the right positioning block 3 are integrally formed.

[0026] When in use, the positioning structure is installed on the pulley combination assembly line, the groove part of the lower mounting surface 6 cooperates with the base plate, and is connected to the assembly line mounting base plate through the mounting hole 4; when loading, first use air to blow the bearing pulley bracket hole workpiece to the position of the new positioning structure, and the two sides of the bearing pulley bracket hole are respectively contacted and positioned with the left positioning block 2 and the right positioning block 3. During this process, the cover plate is in an extended state to prevent the workpiece from being blown away during the movement. After the workpiece is in place, the cover plate returns to its position, and the robot takes the workpiece away for subsequent work.

[0027] By setting up a new positioning structure, the alarm frequency of the equipment during the pulley assembly process is greatly reduced, the defective rate of the pulley assembly after assembly is reduced, the work efficiency is high, and the practicality and adaptability are good; by setting the left positioning block 2 and the right positioning block 3, precise positioning is achieved on both sides of the bearing pulley bracket hole, avoiding the problem of frequent alarms of the equipment and a high defective rate of the assembled product when positioning with the arc surface of the bearing pulley bracket hole.
