[0001] The utility model belongs to the technical field of bench vises, and in particular relates to a bench vise which can be opened and closed quickly. Background Art

[0002] Bench vises are frequently used in the mechanical processing industry. They serve as a clamping tool for workpieces to fix the workpieces. They are generally composed of a base, a top plate, a screw and other structures. They have a simple structure and good stability. They can also be assembled on the processing table of machine tools for use. The general control method of bench vises is to use a wrench to drive the screw to rotate to achieve clamping of the workpiece.

[0003] Since the bench vise can be used for larger or smaller workpieces, if a larger workpiece is to be fixed, it needs to be opened to the appropriate distance before the workpiece can be placed. In order to maintain the stability and accuracy of the workpiece after clamping, the operator is generally required to hold and support the workpiece, and the bench vise needs to be rotated multiple times to fix it. During this process, the operator's hands bear the weight for a long time, and there is oil on some workpieces, so the workpiece is prone to falling. Utility Model Content

[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0021] like Figure 1-Figure 4As shown, a bench vise that can be opened and closed quickly includes a base 1, the base 1 is L-shaped, the top surface of the base 1 is slidably connected to a top plate 2, the end surface of the base 1 is provided with a T-shaped slot 19, and the top plate 2 is slidably connected to the T-shaped slot 19. A support ring 3 is fixedly connected to the top surface of the base 1 near the right end, a sleeve 4 is arranged in the support ring 3, the left end of the sleeve 4 is fixedly connected to the top plate 2, a push rod 5 is arranged in the sleeve 4, and a plurality of positioning components are arranged on the side wall of the sleeve 4, a screw rod 6 is threadedly connected to the right end of the sleeve 4, the left end of the screw rod 6 is rotatably connected to the end surface of the push rod 5, a connecting rod 7 is fixedly connected to the right end of the screw rod 6, and a rocker 8 is assembled on the side wall of the connecting rod 7.

[0022] like Figure 2 and Figure 4 As shown, the positioning assembly includes a groove 9 opened on the side wall of the sleeve 4, the side wall of the groove 9 is fixedly connected with a spring 10, the other end of the spring 10 is fixedly connected with a clamping block 11, the inner wall of the support ring 3 is opened with a plurality of clamping grooves 14, the clamping block 11 is adapted to the clamping groove 14, the side wall of the clamping block 11 close to the center of the sleeve 4 is fixedly connected with a movable rod 12, the other end of the movable rod 12 passes through the sleeve 4 and is movably connected thereto, and the side wall of the push rod 5 is fixedly connected with a plurality of conical blocks 13.

[0023] Specifically, the corners of the block 11 are all inclined, and the width of the block 11 and the slot 14 can be set between 1-5 mm. When fixing the top plate 2, if there is a positional deviation between the block 11 and the slot 14, the inclined surface of the block 11 can also be accurately inserted into the slot 14, thereby achieving the purpose of limiting. The block 11 located on the inner side of the support ring 3 can play a fixing role, and the blocks 11 located on both sides of the support ring 3 can play a limiting role.

[0024] like Figure 4 As shown, the end surface of the movable rod 12 is equipped with a ball 15, and the ball 15 abuts against the side wall of the tapered block 13.

[0025] Among them, the contact method of the ball 15 can reduce the friction between the movable rod 12 and the conical block 13. When the workpiece needs to be loosened, the rocker 8 is reversed, and the force of the spring 10 can be used to drive the block 11 to reset, thereby releasing the fixing operation of the top plate 2.

[0026] like Figure 2 and Figure 4 As shown, a circular hole is formed in the inner wall of the sleeve 4, and the push rod 5 extends into the circular hole. Two sliders 16 are symmetrically fixedly connected to the side wall of the push rod 5 near the left end, and two sliding grooves 17 are formed in the side wall of the circular hole. The sliders 16 are slidably connected to the sliding grooves 17.

[0027] Among them, the push rod 5 and the sleeve 4 are matched with the slider 16 and the slide groove 17, so that the push rod 5 can be kept in a horizontal movement state, ensuring that the clamping block 11 and the clamping groove 14 are always in an aligned state.

[0028] like Figure 1 and Figure 2 As shown, the side walls of the base 1 and the top plate 2 are respectively fixedly connected with anti-skid pads 18, and the side walls of the anti-skid pads 18 are provided with anti-skid patterns. On the one hand, the anti-skid pads 18 are made of rubber material, which has good elasticity, can increase the friction between the workpiece and further improve the fixing effect. On the other hand, they can also protect the surface of the workpiece and reduce the adhesion of iron filings and impurities on the top plate 2, which may cause scratches on the workpiece when subjected to force.

[0029] The working principle of the utility model is as follows: when the workpiece needs to be fixed, the workpiece is first placed between the base 1 and the top plate 2, and then the sleeve 4 is quickly pushed to move, and the sleeve 4 drives the top plate 2 to press against the side wall of the workpiece, and then the rocker 8 is rotated to drive the screw 6 to rotate through the connecting rod 7, and the screw 6 pushes the push rod 5 to move to the left, and the inclined surface of the conical block 13 is used to drive the movable rod 12 to move outward, and the movable rod 12 drives the clamping block 11 to be clamped into the clamping groove 14, and at the same time the spring 10 is stretched to fix the top plate 2, thereby achieving the purpose of quickly fixing the workpiece.

[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
