Technical Field

[0001] The utility model relates to the technical field of mechanical fixture tables, in particular to a mechanical fixture table for machining mechanical parts. Background Art

[0002] Mechanical parts, also known as mechanical elements, are the basic components of machinery and are inseparable individual parts that make up machinery and machines. Mechanical parts are both a discipline that studies and designs the basic mechanical parts of various equipment and a general term for parts and components. Since the emergence of machinery, there have been corresponding mechanical parts, and mechanical fixtures are used in the process of processing parts.

[0003] In order to accommodate a variety of mechanical parts, traditional mechanical clamps generally clamp the parts by moving two clamping plates towards each other. Since there is a circle of tooth blocks on the outer wall of the gear, the stability of the gear clamping cannot be guaranteed when the clamping plates support the gear internally. When the clamping plates clamp the outer wall of the gear, the tooth blocks will be worn. The above clamping method is not applicable to clamping gears. Utility Model Content

[0024] 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.

[0025] See also Figure 1-4 The utility model provides a technical solution: a mechanical fixture table for machining mechanical parts, comprising a workbench 1, a cross 101 connected to the workbench 1, two support rods connected to the workbench 1, the other ends of the two support rods connected to the outer wall of the cross 101, and a gear 2 slidably connected to the cross 101;

[0026] A reverse screw rod 3 is rotatably connected to the cross 101, and a motor is connected to the top of the cross 101. The output end of the motor is sleeved with the top of the reverse screw rod 3. Two screw blocks 301 are threaded on the outer wall of the reverse screw rod 3, and the outer wall of each screw block 301 is connected to a support block 302. Workers hang the gear 2 on the outer wall of the support block 302, and drive the reverse screw rod 3 to rotate through the motor, so that the reverse screw rod 3 drives the screw block 301 to move on the reverse screw rod 3, and then the two support blocks 302 move towards each other, so that the two support blocks 302 have an internal support effect on the gear 2.

[0027] Two sliding rods 4 are fixedly connected to the cross 101, and each sliding rod 4 is slidably connected to a tooth block 403. A spring 402 is arranged outside each tooth block 403, and each tooth block 403 is meshed with the outer wall of the gear 2. After the gear 2 is supported by the two support blocks 302, the tooth block 403 is pushed to be inserted into the tooth block on the outer wall of the gear 2. Under the elastic action of the spring 402, the tooth block 403 can be stably meshed with the tooth block outside the gear 2, thereby further limiting the gear 2.

[0028] Each slider 401 is slidably connected with a baffle 404 . The baffle 404 moves inside the slider 401 to limit the outer wall of the gear 2 , thereby reducing the risk of the gear 2 falling off the support block 302 .

[0029] The outer wall of each support block 302 is connected to a connecting plate 303, and the outer wall of the connecting plate 303 is provided with anti-slip grooves. Under the action of the connecting plate 303, when a worker hangs the gear 2 on the support block 302, the outer wall of the gear 2 can be directly abutted against the connecting plate 303, thereby positioning the placement of the gear 2. By setting the anti-slip grooves, the friction between the connecting plate 303 and the gear 2 is increased, thereby improving the stability of the gear 2 after placement.

[0030] The outer wall of each support block 302 is arranged to be arc-shaped, and the outer wall of each support block 302 is in close contact with the inner wall of the gear 2. The arc-shaped arrangement can make the outer wall of the support block 302 fit more closely to the inner wall of the gear 2, further increasing the contact area between the support block 302 and the gear 2, thereby increasing the friction force and further improving the stability of the gear 2 on the outer wall of the support block 302.

[0031] The outer wall of each slide rod 4 is slidably connected with a slider 401, each slider 401 is connected to the outer wall of the tooth block 403, the outer wall of each slider 401 is connected to a spring 1 402, and the other end of each spring 1 402 is connected to the cross 101. Under the elastic action of the spring 1 402, the slider 401 moves on the slide rod 4 until the end of the tooth block 403 meshes with the outer wall of the gear 2, thereby improving the positioning effect of the support block 302 on the gear 2.

[0032] Each slider 401 is slidably connected to a T-shaped block 405, and the outer wall of each T-shaped block 405 is connected to a baffle 404. Each slider 401 is connected to a spring 2 406, and the other end of each spring 2 406 is connected to the outer wall of the T-shaped block 405. Under the action of the spring 2 406, when the baffle 404 is pulled and then released, the T-shaped block 405 can drive the baffle 404 to quickly return to its original position, so that the side of the baffle 404 close to the tooth block 403 can be attached to the outer wall of the gear 2, further limiting the gear 2.

[0033] A water tank is provided inside the workbench 1, and a filter screen 5 is connected to the inner wall of the water tank. The bottom end of the workbench 1 is in contact with the surface of the filter screen 5. When the gear 2 is processed on the support block 302, debris will fall onto the surface of the filter screen 5. When water is used to flush the gear 2, the filter screen 5 can separate the debris and water.

[0034] A water pump 501 is connected to the inside of the water tank, and the water outlet end of the water pump 501 is connected and fixedly connected to a water pipe 502. The other end of the water pipe 502 is connected to the top of the cross 101. By starting the water pump 501, the water pump 501 can draw water from the water tank into the water pipe 502 and spray it out, thereby cleaning the gear 2, allowing water resources to be recycled and reducing water resource waste.

[0035] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
