Description

Technical Field

[0001] This utility model relates to the field of bench vise technology, specifically to a convenient bench vise. Background Technology

[0002] A bench vise, also known as a bench clamp, is a general-purpose clamping tool used to hold workpieces. A bench vise consists of a fixed jaw and a movable jaw. The movable jaw is slidably inserted into the fixed jaw via guide rails. The workpiece is clamped by closing the fixed and movable jaws. Since the fixed jaw is typically fixed to the base, the workpiece clamping direction of existing bench vises is fixed. When the workpiece is tilted, it is difficult to clamp it, affecting the clamping effect. Furthermore, when using a bench vise outdoors, the guide rails of the movable jaw are prone to rust, affecting the smoothness of the movable jaw's operation and shortening the service life of the bench vise.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A bench vise includes a support base, a vise body assembly and a connector. The vise body assembly is rotatably mounted on the support base. A locking screw is installed on the support base. The locking screw is used to lock the vise body assembly. The vise body assembly includes a first vise body and a second vise body. The first vise body and the second vise body cooperate to form a first clamping part. The second vise body passes through the support base and is connected to the connector.

[0005] Based on the above technical solution, the present invention can be further improved as follows:

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figures 1 to 5As shown, this utility model discloses a bench vise, including a base 1, a support 2, a vise body assembly, and a connector 8. The support 2 is mounted on the base 1, and the vise body assembly is rotatably mounted on the support 2. The support 2 is provided with a locking screw 10 for locking the vise body assembly. The vise body assembly includes a first vise 3 and a second vise 4. The second vise 4 passes through the support 2 and is connected to the connector 8. Specifically, the second vise 4 is connected to the connector 8 by two screws 13 arranged symmetrically to ensure the firmness of the connection between the connector 8 and the second vise 4 and to prevent the second vise 4 from detaching from the support 2, thus ensuring the stability of the installation of the second vise 4. The first vise 3 and the second vise 4 cooperate to form a first clamping part 5, which includes a flat jaw and a pipe jaw formed by two V-grooves. The V-grooves are provided on the flat jaw for clamping workpieces of different shapes. The support base 2 is provided with a receiving cavity through which the second clamp body 4 passes. The locking screw 10 is installed on the side wall of the receiving cavity. According to the shape of the workpiece to be clamped, the clamp body assembly is rotated to a certain angle, and the locking screw 10 is screwed inward so that the end of the locking screw 10 abuts against the outer wall of the second clamp body 4, thereby locking the clamp body assembly and ensuring the stability when clamping the workpiece.

[0021] Furthermore, a rotating handle is installed on the outside of the locking screw 10 to facilitate the rotation of the locking screw 10 and improve the ease of operation.

[0022] In this embodiment, specifically, the support base 2 is provided with multiple scales 11, which are adjacent to the second clamp body 4. The multiple scales 11 are evenly arranged along the circumference of the support base 2. This allows users to intuitively understand the rotation angle, enabling them to quickly rotate the clamp body assembly to a specified angle and improving operating efficiency.

[0023] In this embodiment, specifically, the connector 8 includes an inner connecting sleeve 8.2. A lead screw 7 is installed on the first clamp body 3, and a handle is installed on the lead screw 7 to facilitate rotation of the lead screw 7. The lead screw 7 is threadedly connected to the inner connecting sleeve 8.2. The first clamp body 3 is inserted into the second clamp body 4 through a slide rail 12. The first clamp body 3 and the slide rail 12 are an integral structure, reducing the number of parts and ensuring the structural strength of the first clamp body 3. The end of the lead screw 7 is connected to the slide rail 12 through a washer and a nut. Therefore, when the lead screw 7 is rotated, it can drive the first clamp body 3 to move synchronously, realizing the closing and separation of the first clamp body 3 and the second clamp body 4, thereby realizing the clamping or releasing of the workpiece.

[0024] Furthermore, one end of the connector 8 is provided with a positioning block 8.1, and the second clamp body 4 is provided with a corresponding positioning groove. Through the cooperation of the positioning block 8.1 and the positioning groove, the positions of the connector 8 and the second clamp body 4 are limited, reducing the difficulty of installing the screw 13 and improving the convenience of operation.

[0025] In this embodiment, specifically, an outer connecting sleeve 8.3 is provided on the outside of the inner connecting sleeve 8.2, and a space for the slide rail 12 to pass through is provided between the inner connecting sleeve 8.2 and the outer connecting sleeve 8.3. The inner connecting sleeve 8.2 is connected to the outer connecting sleeve 8.3 by a radially arranged connecting rib. The slide rail 12 has an arc-shaped cross-section, and an avoidance groove 14 is provided on the slide rail 12 for the connecting rib to pass through. The avoidance groove 14 is arranged along the length direction of the slide rail 12 to ensure that the slide rail 12 can move normally.

[0026] Furthermore, a protective cover 9 is installed on the outer connecting sleeve 8.3, and the protective cover 9 covers the outside of the slide rail 12. The protective cover 9 protects the slide rail 12 and the lead screw 7, solving the problem of corrosion affecting the normal use of the bench vise and improving the service life of the bench vise. Specifically, the protective cover 9 is connected to the external thread of the outer connecting sleeve 8.3 through its internal thread. The connection between the protective cover 9 and the outer connecting sleeve 8.3 is coated with locking adhesive to further ensure the firmness of the connection.

[0027] Furthermore, the protective cover 9 is made of metal, such as stainless steel, which improves the service life of the protective cover 9, prevents the protective cover 9 from being bumped and broken, and ensures the protective effect.

[0028] The bench vise also includes a second clamping part 6, which includes two mating clamping slots, respectively mounted on the first clamping body 3 and the second clamping body 4. The second clamping part 6 and the first clamping part 5 are located on both sides of the lead screw 7, enabling simultaneous clamping of workpieces of different shapes, or separate clamping of workpieces of different shapes, further improving ease of use and reducing operating costs.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
