[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a fixture for machining sliding cylinders, comprising a main body 1, a first clamping plate 2 disposed at one upper end of the main body 1, a slide rail 3 disposed inside the main body 1, a support column 4 disposed on the side wall of the main body 1, a connecting rod 5 penetrating through the inner wall of the support column 4, a first handle 6 fixed to one end of the connecting rod 5, a first support rod 7 disposed at the other end of the connecting rod 5, a first bearing 8 disposed on the outer surface of the first support rod 7, a second support rod 9 disposed on the outer surface of the first bearing 8, a second bearing 10 disposed at one end of the second support rod 9, and a third support rod 10 disposed on the outer surface of the second bearing 10. The support rod 11 has a third bearing 12 inside it, a fourth support rod 13 on the inner wall of the third bearing 12, a support plate 14 at one end of the fourth support rod 13, an arc-shaped friction plate 15 fixed below the third support rod 11, an internal threaded plate 16 fixed above the support column 4, a threaded column 17 internally threaded to the internal threaded plate 16, a second handle 18 at one end of the threaded column 17, a fourth bearing 19 at the other end of the threaded column 17, a second clamping plate 20 on the outer surface of the fourth bearing 19, and a rubber pad 21 at one end of the second clamping plate 20.

[0020] The support column 4 and the connecting rod 5 form a pull-out structure, and the first handle 6 forms a fixed structure between the connecting rod 5 and the first support rod 7, which makes the operation of fixing the slide table simpler.

[0021] The first support rod 7 forms a movable structure with the second support rod 9 through the first bearing 8, the second support rod 9 forms a movable structure with the third support rod 11 through the second bearing 10, and the third support rod 11 forms a movable structure with the fourth support rod 13 through the third bearing 12, thereby providing the advantage of convenient control over the arc-shaped friction plate 15.

[0022] The fourth support rod 13 forms a fixed structure with the support plate 14 and the support column 4, so that the arc-shaped friction plate 15 can reciprocate in an arc with the fourth support rod 13 as the center, which achieves the benefit of fixing the slide table when it reaches a specific position.

[0023] The built-in threaded plate 16 and the threaded post 17 form a threaded connection. The threaded post 17 forms a rotating structure with the second clamping plate 20 through the fourth bearing 19, thereby securing the material on the main body 1.

[0024] Working principle: For this type of fixture used for machining sliding cylinders, when working on the main body 1, firstly, slide the slide rail 3 inside the main body 1 to the required position and pull the first handle 6. Since the first handle 6 controls the arc-shaped friction plate 15 to move in an arc shape with the fourth support rod 13 as the center, the slide rail 3 is fixed by the friction between the arc-shaped friction plate 15 and the slide rail 3. Then, place the production material on the main body 1, and then rotate the second handle 18, so that the second handle 18 drives the threaded column 17 to rotate. Since the fourth bearing 19 is provided at the connection between the threaded column 17 and the second clamping plate 20, the second clamping plate 20 is driven to move horizontally, and the rubber pad 21 on the surface of the second clamping plate 20 will reduce the damage to the material. When the clamping force required by the operator is reached, the rotation stops and the work begins.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
