DETAILED DESCRIPTION

[0026] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] As attached Figure 1 To Attachment Figure 5 As shown:

[0028] Embodiment 1: The utility model provides a gear processing fixture, including a support plate 1 for supporting a turntable 23 , wherein a fixing frame 11 for fixing a motor 21 is fixedly connected to the bottom of the support plate 1 .

[0029] As can be seen from the above, the motor 21 can be fixed by the fixing bracket 11 , thereby ensuring the stable output of the motor 21 .

[0030] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the rotating unit 2 includes a motor 21 disposed at the bottom of the support plate 1 for driving the rotating shaft 22 to rotate, and the motor 21 is fixedly installed in the fixing frame 11.

[0031] Furthermore, a rotating shaft 22 for driving the turntable 23 to rotate is fixedly connected to the output end of the motor 21 , and one end of the rotating shaft 22 vertically penetrates the support plate 1 , and the rotating shaft 22 is rotatably connected to the support plate 1 .

[0032] Furthermore, a rotating disk 23 for driving the engaging unit 3 to work is fixedly connected to one end of the rotating shaft 22 penetrating the supporting plate 1 , and the rotating disk 23 is rotatably connected to the supporting plate 1 .

[0033] Furthermore, a plurality of limiting sliding grooves 24 for accommodating the sliding rods 38 are evenly arranged vertically downward on the top of the rotating disk 23 .

[0034] As can be seen from the above, by starting the motor 21, the motor 21 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the turntable 23 to rotate. During the rotation of the turntable 23, the position of the limiting slide groove 24 moves, and the limiting slide groove 24 pushes the slide rod 38 to move when moving, thereby allowing the locking unit 3 to work.

[0035] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the locking unit 3 includes slide rails 31 arranged at the four corners of the top of the support plate 1 to facilitate the movement of the slider 32, and the slide rails 31 are slidably connected to the slider 32 to facilitate the movement of the fixed plate 33.

[0036] Furthermore, a fixing plate 33 is fixedly connected to the top of the slider 32 for driving the clamping block 34 to move, a clamping block 34 for clamping the inner ring of the gear is arranged on the top of one end of the fixing plate 33, and a receiving groove 35 for accommodating the first rubber block 36 is horizontally opened on one side of the clamping block 34, and the first rubber block 36 for protecting the contact surface of the inner ring of the gear is embedded in the receiving groove 35.

[0037] Furthermore, a second rubber block 37 for supporting one side of the gear is disposed on one side of the clamping block 34 . The second rubber block 37 is fixedly connected to the fixing plate 33 . The height of the second rubber block 37 is higher than the bottom of the first rubber block 36 .

[0038] Furthermore, a sliding rod 38 is fixedly connected to the bottom of the fixing plate 33 for driving the fixing plate 33 to move, and one end of the sliding rod 38 is located in the limiting sliding groove 24 .

[0039] As can be seen from the above, when the gear needs to be processed, the motor 21 is started first to reverse the motor 21, and the motor 21 drives the rotating shaft 22 and the turntable 23 to reverse. When the turntable 23 reverses, the limiting slide groove 24 drives the slide rod 38 to move, and the slide rod 38 drives the fixed plate 33 to move toward the center of the turntable 23 along the direction of the slide rail 31 under the action of the slider 32 and the slide rail 31, so that the block 34 is at the center of the turntable 23.

[0040] Furthermore, when the slider 32 slides to the end of the travel of the slide rail 31, the motor 21 is stopped. At this time, the gear is put on the block 34 so that the block 34 is inside the inner ring of the gear. At this time, the top of the second rubber block 37 can support one side of the gear, and the height of the second rubber block 37 is higher than the height of the bottom of the first rubber block 36. Therefore, the inner ring of the gear can be prevented from contacting the surface of the block 34, thereby protecting the contact surface of the inner ring of the gear and preventing the block 34 from causing wear when contacting the inner ring of the gear.

[0041] Furthermore, when the gear is placed, the motor 21 is started to make the motor 21 rotate forward. Similarly, when the turntable 23 rotates forward, the limiting slide groove 24 drives the slide rod 38 to move. The slide rod 38 drives the fixing plate 33 to move away from the center of the turntable 23 along the direction of the slide rail 31 under the action of the slider 32 and the slide rail 31. As the slider 32 continues to move, the clamping block 34 slowly drives the first rubber block 36 to contact and squeeze the inner ring of the gear, thereby fixing the gear. When the first rubber block 36 contacts the inner ring of the gear, it not only protects the outer ring of the gear, but also increases the friction with the inner ring of the gear, so that the gear is not easy to shift when the gear is processed.

[0042] Through the above operations, the gear processing fixture can clamp the gear from the inner ring of the gear to avoid damage to the gear teeth. The first rubber block 36 can avoid wear of the inner ring of the gear when clamping the inner ring of the gear. The second rubber block 37 can avoid wear on the side of the gear. At the same time, through the setting of the card and the unit, the gear clamp can clamp gears of different sizes, greatly improving the application range of the gear processing fixture.

[0043] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
