DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0026] Reference Figure 1-Figure 6 A clamping tool for machining shaft parts, comprising a body 1, a placement opening 2 is provided on the upper surface of the body 1, a mounting cavity is provided in the body 1, a rotating rod 3 is rotatably installed in the mounting cavity, a first gear 4 is fixedly sleeved on the rotating rod 3, through openings are provided on both left and right side walls of the body 1, a first rack rod 5 is slidably inserted in the through openings, two first rack rods 5 are meshed and connected with the first gear 4, and a pressing block 7 is fixedly installed on one end of the first rack rod 5 located outside the mounting cavity through a connecting rod 6;

[0027] One end of the rotating rod 3 passes through the body 1 and is fixedly sleeved with the second gear 8. A placement plate is fixedly installed on the surface of the body 1. A first threaded rod 9 is rotatably installed on the surface of the placement plate. A slider 10 is threadedly sleeved on the first threaded rod 9. A second rack rod 11 meshingly connected with the second gear 8 is fixedly installed on the top of the slider 10. The slider 10 is restricted in rotation by a restriction component. The restriction component includes a restriction groove 12 horizontally opened on the body 1 and a restriction rod 13 fixedly installed on the surface of the slider 10. One end of the restriction rod 13 is slidably arranged in the restriction groove 12. The first rack rod 5 is horizontally slidably arranged in the installation cavity through a sliding component. The sliding component includes a slide groove 22 horizontally opened on the wall of the installation cavity and a sliding rod 23 with one end slidably arranged in the slide groove 22. The two sliding rods 23 are fixedly connected to the two first rack rods 5 respectively.

[0028] First, place the shaft part to be processed in the placement port 2, and then by rotating the first threaded rod 9, the slider 10 threadedly sleeved on the first threaded rod 9 will move horizontally with the second rack rod 11 under the limiting action of the limiting groove 12 and the limiting rod 13. During the movement, the second gear 8 meshing with the second rack rod 11 will rotate with the rotating rod 3 and the first gear 4, so that the two first rack rods 5 meshing with the first gear 4 will move relative to each other in the horizontal direction, until the two pressing blocks 7 are in contact with the shaft part, the shaft part can be pressed and clamped in the placement port 2.

[0029] The surface of the pressing block 7 is bonded with an anti-skid layer made of rubber. The rubber anti-skid layer has good elasticity and viscosity, thereby increasing the friction between the pressing block 7 and the contact surface of the shaft parts.

[0030] A second threaded rod 14 is rotatably mounted on the back of the machine body 1, and a slide plate 15 is threadedly sleeved on the second threaded rod 14. An adsorption assembly is provided on the surface of the slide plate 15, and the adsorption assembly is used to adsorb the ends of shaft parts. A slide bar 16 is provided on the back of the machine body 1, and the slide plate 15 is slidably sleeved on the slide bar 16. The adsorption assembly includes a hollow rod 17 fixedly mounted on the surface of the slide plate 15 and a suction cup 18 fixedly mounted on the end of the hollow rod 17. A through hole connected to the hollow rod 17 is opened on the surface of the slide plate 15, and a rotating shaft 19 is sealed and rotatably mounted in the through hole. One end of the rotating shaft 19 located in the hollow rod 17 is fixedly mounted with a covering plate 20 through a connecting rod. A vent 21 is opened on the surface of the hollow rod 17, and a magnet is arranged in the covering plate 20. The vent 21 is made of magnetic material;

[0031] When the two pressing blocks 7 press the shaft part into the placement opening 2, the second threaded rod 14 is rotated, and the slide plate 15 threadedly sleeved on the second threaded rod 14 will move the hollow rod 17 and the suction cup 18 toward the end of the shaft part under the restriction of the slide rod 16, until the suction cup 18 contacts the shaft part. At this time, since the cover plate 20 covers the vent 21, the gas in the hollow rod 17 will slip out from the gap between the suction cup 18 and the contact surface of the shaft part, thereby completing the fixation of the end of the shaft part and improving the stability of fixing the shaft part.

[0032] When the adsorption needs to be released, the cover plate 20 can be controlled to no longer cover the vent 21 by rotating the rotating shaft 19. At this time, the gas in the outside will enter the hollow rod 17 from the vent 21, thereby releasing the adsorption of the suction cup 18 on the shaft parts.

[0033] In the utility model, the shaft parts to be processed are first placed in the placement port 2, and then by rotating the first threaded rod 9, the slider 10 threadedly sleeved on the first threaded rod 9 will move the second rack rod 11 in the horizontal direction under the limiting action of the limiting component. During the movement, the second gear 8 meshing with the second rack rod 11 will rotate with the rotating rod 3 and the first gear 4, so that the two first rack rods 5 meshing with the first gear 4 will move relative to each other in the horizontal direction, until the two pressing blocks 7 are both against the shaft parts, the shaft parts can be pressed and clamped in the placement port 2, and shaft parts of different sizes can be clamped quickly. The clampable shaft parts are no longer of a certain size, which improves the practicality of the device.

[0034] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
