At the end of the 19th century, the principle of gear cutting and special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation has received attention.

[0003] For example, a gear processing positioning platform is disclosed in the Chinese utility model patent publication number (CN218946541 U), which includes a positioning platform body and a positioning column. A positioning column for passing through the center hole of the gear is vertically fixed on the surface of the positioning platform body. Two clamping plates for clamping the gear are slidably connected to the surface of the positioning platform body. The two clamping plates are symmetrical to each other. A reset mechanism is connected between the clamping plates and the positioning platform body. A lifting mechanism is provided under the positioning platform body. Two inclined blocks for pushing the clamping plates are installed on the lifting mechanism. An ejection mechanism for ejecting the gear out of the positioning column is installed on the lifting mechanism. This utility model solves the problem that the existing gear positioning mechanism requires multiple sets of power mechanisms to clamp the gear, has a complex structure, is costly, and requires manual removal of the gear. However, the position and size of the positioning column in this patent are fixed, and only gears of a specific size can be positioned, and gears of different inner diameters cannot be positioned. The clamping plates on both sides can only position the left and right positions of the gear, resulting in reduced processing efficiency of the gear, affecting practicality. Utility Model Content

DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1 A gear processing positioning table in this embodiment includes a processing table 1, a connecting box 2 is fixed to the lower surface of the processing table 1, and a positioning mechanism 3 for positioning and fixing the gear is provided on the connecting box 2, so that the equipment can adapt to gears of different inner diameters. A material taking mechanism 4 for removing the processed gears is provided on the processing table 1, which is convenient for the staff to take away the processed gears.

[0024] Among them, four brackets 5 are fixed to the lower surface of the processing table 1 and are evenly distributed at the four corners of the lower surface of the processing table 1, so that the processing table 1 can maintain stability during gear processing.

[0025] See also Figure 2-3In order to make the device adaptable to gears of different inner diameters, the positioning mechanism 3 in this embodiment includes a motor 301, which is fixed to the lower surface of the connection box 2. The output shaft of the motor 301 penetrates and extends into the interior of the connection box 2, and a rotating plate 302 is fixed thereto. The output shaft of the motor 301 drives the rotating plate 302 to rotate. A sliding opening 303 is provided on the upper surface of the rotating plate 302. The rotating plate 302 drives the sliding opening 303 to rotate. A connecting rod 304 is provided inside the sliding opening 303. The sliding opening 303 rotates to squeeze the connecting rod 304, so that the connection The rod 304 is pushed to move, a slider 305 is fixed to the lower surface of the connecting rod 304, a slide rail 306 is fixed to the inner bottom wall of the connecting box 2, and the slider 305 is slidably connected to the inner side of the slide rail 306. Since the connecting rod 304 is connected to the slider 305, the slider 305 slides on the slide rail 306, so the slide 303 rotates to make the connecting rod 304 move linearly along the direction of the slide rail 306. The top end of the connecting rod 304 passes through and extends to the upper side of the processing table 1, and is fixed with a fixed block 307. The connecting rod 304 drives the fixed block 307 to move.

[0026] In this example, the number of the slides 303 is not less than two, and they are symmetrically distributed around the central axis of the rotating plate 302. The number of connecting rods 304 is equal to the number of the slides 303, and the positions correspond one to one, so that the fixing block 307 is opened outward on the inner side of the gear to be processed, so that the position of the gear to be processed can be positioned and fixed. The outer diameter of the connecting rod 304 is adapted to the width of the slide 303, so that the connecting rod 304 can be pushed a certain distance every time the slide 303 rotates a certain angle, thereby facilitating the movement of the connecting rod 304. A plurality of first connecting ports are provided on the upper surface of the processing table 1, and the number of the first connecting ports is equal to the number of the connecting rods 304, and the positions correspond one to one. The width of the first connecting port is adapted to the outer diameter of the connecting rod 304, so that the connecting rod 304 can move on the processing table 1.

[0027] See also Figure 4-5 In order to facilitate the staff to take away the processed gears, the material taking mechanism 4 in this embodiment includes an electric push rod 401, which is fixed to the lower surface of the processing table 1. The output shaft of the electric push rod 401 passes through and extends to the upper side of the processing table 1, and is fixed with a support rod 402. The output shaft of the electric push rod 401 drives the support rod 402 to move, and a placement plate 403 is fixed to the other end of the support rod 402. The support rod 402 drives the placement plate 403 to move, and the placement plate 403 drives the processed gear to move, so that the gear moves to the top of the fixed block 307, which is convenient for the staff to take away the gears. A second connecting port 404 is opened on the upper surface of the placement plate 403, and the fixed block 307 is located on the inner side of the second connecting port 404. The number of the second connecting ports 404 is equal to the number of the fixed blocks 307, and the positions correspond one to one. The width of the second connecting port 404 is adapted to the width of the fixed block 307.

[0028] In this example, there are two electric push rods 401 , which are symmetrically distributed about the central axis of the processing table 1 , so that the placement plate 403 maintains stability when moving.

[0029] The working principle of the above embodiment is:

[0030] (1) First, place the gear to be processed on the placement plate 403, and make the fixed block 307 located on the inner side of the gear to be processed. At this time, turn on the motor 301, and the output shaft of the motor 301 drives the rotating plate 302 to rotate, and the rotating plate 302 drives the sliding mouth 303 to rotate. The sliding mouth 303 rotates to squeeze the connecting rod 304, so that the connecting rod 304 is pushed to move. Since the connecting rod 304 is connected to the slider 305, the slider 305 slides on the slide rail 306, the sliding mouth 303 rotates to make the connecting rod 304 move linearly along the direction of the slide rail 306, and the connecting rod 304 drives the fixed block 307 to move, so that the fixed block 307 opens outward on the inner side of the gear to be processed, so that the position of the gear to be processed can be positioned and fixed.

[0031] (2) After the position of the gear to be processed is located and fixed, the gear can be processed. When the gear is processed, it is not convenient to take out the gear because one side of the gear is in contact with the placement plate 403 and the fixing block 307 passes through the inner side. Therefore, it is necessary to turn on the motor 301 again to control the rotating plate 302 to rotate in the opposite direction so that the fixing block 307 returns to the initial position. Then, the electric push rod 401 is turned on. The output shaft of the electric push rod 401 drives the support rod 402 to move, and the support rod 402 drives the placement plate 403 to move. The placement plate 403 drives the processed gear to move, so that the gear is moved to the top of the fixing block 307, which is convenient for the staff to take out the gear.
