DETAILED DESCRIPTION
[0015] The utility model will be further described below with reference to the drawings.
[0016] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following will be further detailed with reference to the drawings and specific embodiment. It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
[0017] Reference Figs. 1-2 A jig for shaft machining, comprising a base 1, the base 1 is U-shaped structure, the middle is a slide groove 2, and strip guide slots 3 are formed in the left and right side walls, a pair of stand 4 is slidably arranged in the slide groove 2, guide blocks 5 are arranged on the left and right sides of the stand 4, the guide blocks 5 are arranged through the strip guide slots 3, support plates 6 are transversely arranged on the top of the stand 4, and the two support plates 6 extend in opposite directions, the support plate 6 is arc-shaped structure, and a plurality of rollers 7 are arranged in the inside. Specifically, since the support plate 6 can slide in the slide groove 3 through the stand 4, the distance between the support plates 6 can be adjusted, and the support plate 6 extends outward, thereby extending the supporting range, so that the different shafts within a certain length range can be used for auxiliary machining. At the same time, since the support plate 6 extends outward, the length of the base 1 can be shortened, so that the volume of the whole jig can be reduced for easy storage. When the stand 4 moves, the guide blocks 5 slide in the guide slots 3, improving the stability of the stand movement. The support plate 6 and the roller 7 are used for supporting the shaft.
[0018] In the embodiment, the chute 3 is provided with an upward protruding guide rail 8 at the bottom, and the upright column 4 is provided with a guide chute 9 at the bottom, and the guide chute 9 cooperates with the guide rail 8. The guide chute 9 cooperates with the guide rail 8, which not only limits the upright column 4, but also improves the stability of movement.
[0019] In the embodiment, a pair of slide rails 10 are arranged outside the left and right side walls of the base 1, and the slide rails 10 are arranged above and below the strip-shaped guide chute 3, respectively. The outer end of the guide block 5 is provided with a sliding block 11, and the sliding block 11 cooperates with the upper and lower slide rails. When the guide block 5 moves, the sliding block 11 and the slide rail 10 cooperate with each other, which improves the stability of movement.
[0020] In the embodiment, a handle 12 is arranged on the outer wall of the sliding block 11. The handle 12 is convenient for holding the upright column 4 to move.
[0021] In the embodiment, the upright column 4 is a split structure, including a lower upright column 41 and an upper upright column 42. An installation groove is arranged in the center of the lower upright column 41, and a motor 43 is arranged in the installation groove. The output shaft of the motor 43 is provided with a screw rod 44, and the screw rod 44 is provided with a nut 45. The lower upright column 41 and the upper upright column 42 are slidingly connected. A guide groove 46 is arranged in the center of the lower upright column 41, and a guide column 47 is arranged below the upper upright column 42. The guide column 47 is inserted into the guide groove 46. A through hole 48 is arranged in the guide column 47, and the nut 44 is fixed in the through hole 48. In order to adapt to different specifications of the shaft for processing, the upright column 4 can be lifted. Specifically, after the motor 43 is started, the screw rod 44 is rotated to drive the nut 45 to lift. The upper upright column 42 is lifted under the action of the guide column 47 and the guide groove 46, that is, the supporting plate 6 is lifted, so as to meet the use of different specifications of the shaft.
