Description

Technical Field

[0001] This utility model relates to the field of clamping tool technology, and in particular to a bench vise. Background Technology

[0002] Existing pneumatic vises have several shortcomings in structure and use. First, most of their key load-bearing components are directly fixed to the base plate, and there are no precise positioning elements at the connection points. During prolonged use, these key load-bearing components are prone to displacement due to frequent clamping, a phenomenon known as "misalignment," which affects the machining accuracy of the clamped parts. Second, the adjustment mechanism of the movable vise body usually slides and locks directly on the base plate, resulting in high sliding friction, uneven adjustment, and difficulty in achieving fast and precise positioning.

[0003] Furthermore, in terms of fixing methods, traditional vises mostly use clamps on both sides for fixation. This structure has a large lateral dimension, and when multiple units are used side by side, this method not only results in a loose structure and large cumulative errors, but also further increases the overall space occupied. Finally, the air pipeline layout of traditional pneumatic vises is relatively random and messy, which not only occupies extra space, but may also interfere with the operation process and pose safety hazards. Utility Model Content

[0004] Therefore, in response to at least one of the above problems, this utility model provides a bench vise.

[0005] This utility model is achieved using the following solution:

[0006] This utility model proposes a bench vise, including a base plate, a stop block assembly, and a sliding block assembly. The stop block assembly is fixed on the base plate, and the sliding block assembly is displaceably disposed on the base plate. The base plate is provided with a sliding groove, and a slider is slidably engaged in the sliding groove. The sliding block assembly and the slider can be brought close to each other by a connecting member to clamp the base plate, thereby locking the sliding block assembly on the base plate. An elastic member is provided between the sliding block assembly and the slider.

[0007] In one embodiment, the elastic element is a hollow ring structure, the connecting element is rod-shaped, and the elastic element is circumferentially arranged around the connecting element.

[0008] In one embodiment, the elastic element is a spring, the connecting element is a bolt, and the elastic element is circumferentially arranged around the bolt; and / or,

[0009] The slider is a T-shaped slider, and the groove is a T-shaped groove.

[0010] In one embodiment, the sliding block assembly includes a sliding connecting block and a first clamping block, and the stop block assembly includes a positioning stop and a second clamping block; a first positioning element is provided between the first clamping block and the sliding connecting block; and / or,

[0011] A second positioning element is provided between the second clamping block and the positioning stop; and / or,

[0012] A third positioning element is provided between the positioning block and the base plate.

[0013] In one embodiment, the first positioning element, the second positioning element, and the third positioning element are all positioning sleeves, and are respectively coaxially arranged with each bolt hole. The bolt holes are used to pass bolts through to realize the connection of adjacent elements.

[0014] In one embodiment, the number of the first positioning element, the second positioning element, and the third positioning element is at least two.

[0015] In one embodiment, the sliding connecting block is locked onto the guide slider; a guide rail is installed on the base plate, and the guide slider is slidably engaged with the guide rail.

[0016] In one embodiment, there are two guide sliders, two guide rails, two sliders and two slide grooves. The two guide rails are located on the outside of the two slide grooves, and a base plate mounting groove is provided in the middle of the two slide grooves.

[0017] In one embodiment, the bench vise is a pneumatic bench vise, and the sliding block assembly further includes an adjusting block and a cylinder. The cylinder is mounted on the adjusting block, the upper end of the elastic element abuts against the adjusting block, and the lower end of the elastic element abuts against the slider.

The pressure regulating valve and the manual control valve are mounted on the tail of the cylinder via an L-shaped mounting bracket, and the pressure regulating valve and the manual control valve are mounted on the inner side of the L-shaped mounting bracket.

[0019] The technical solution provided by this utility model has the following technical effects:

[0020] 1. This utility model provides a bench vise, including a base plate, a stop block assembly, and a sliding block assembly. The stop block assembly is fixed to the base plate, and the sliding block assembly is displaceably disposed on the base plate. The base plate has a sliding groove, and a slider is slidably engaged with the sliding groove. The sliding block assembly and the slider can be brought close to each other by a connecting member to clamp the base plate, thereby locking the sliding block assembly on the base plate. An elastic member is provided between the sliding block assembly and the slider. When the connecting member between the sliding block assembly and the slider is released, the elastic potential energy stored in the elastic member is released, thereby pushing the slider to separate from the sliding groove and create a gap. This greatly reduces the sliding friction between the slider and the base plate, making the adjustment of the sliding block assembly smoother and easier to achieve fast and accurate positioning.

[0021] 2. A first positioning element is provided between the first clamping block and the sliding connecting block; a second positioning element is provided between the second clamping block and the positioning stop; and a third positioning element is provided between the positioning stop and the base plate. This makes it difficult for the force-bearing element to be displaced under frequent force clamping, which greatly improves the positioning accuracy of the clamped part and thus indirectly improves the processing accuracy of the clamped part.

[0022] 3. The air pressure regulating valve and the manual control valve are mounted at the tail of the cylinder via an L-shaped mounting bracket, and the air pressure regulating valve and the manual control valve are mounted on the inside of the L-shaped mounting bracket, making the overall air circuit neater, not affecting the operation process, and the overall device more compact.

[0030] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figures 1-7 As shown, this embodiment provides a bench vise 1, which can be a pneumatic bench vise, including a base plate 10, a stop block assembly 20, a sliding block assembly 30, and a pneumatic control assembly 40. The stop block assembly 20 is fixed on the base plate 10, and the sliding block assembly 30 is displaceably disposed on the base plate 10. The base plate 10 is provided with a sliding groove 16, and a slider 14 is slidably engaged in the sliding groove 16. The sliding block assembly 30 and the slider 14 can be brought close to each other by a connecting member (not shown) to clamp the base plate 10, thereby locking the sliding block assembly 30 on the base plate 10; the connecting member can be, for example, a bolt.

[0033] However, in existing technologies, the slider 14 is in direct contact with the groove 16, and the slider 14 slides and locks directly on the base plate 10. This results in high sliding friction between the slider 14 and the base plate 10, making adjustment difficult and hindering rapid and precise positioning. Therefore, in this solution, an elastic element 15 is provided between the slider assembly 30 and the slider 14. When the slider assembly 30 and the slider 14 are close together and locked, the elastic element 15 is elastically compressed between them. When the connecting piece between the slider assembly 30 and the slider 14 is released, the elastic potential energy stored in the elastic element 15 is released, thereby pushing the slider 14 and causing it to separate from the groove 16, creating a gap. This significantly reduces the sliding friction between the slider 14 and the base plate 10, making the adjustment of the slider assembly 30 smoother and facilitating rapid and precise positioning.

[0034] The elastic element 15 has a hollow ring structure, and the connecting member is rod-shaped. The elastic element 15 is circumferentially arranged around the connecting member, thereby providing better limiting of the elastic element 15 and enabling it to be positioned more effectively. In this embodiment, the elastic element 15 is a spring, and the connecting member is a bolt. In other embodiments, the elastic element 15 can also be an elastic tube, etc. The connecting member between the sliding block assembly 30 and the slider 14 does not have to be a bolt; the connecting member can be a telescopic rod, etc.

[0035] In this embodiment, slider 14 is a T-shaped slider and groove 16 is a T-shaped groove, which enables better guidance; however, it is not limited to this. In some other embodiments, slider 14 may also be a flat slider.

[0036] In this embodiment, the sliding block assembly 30 is movable on the base plate 10 so that the telescopic pressing block assembly 30 approaches or moves away from the stop block assembly 20. The clamped object (not shown) is disposed between the stop block assembly 20 and the sliding block assembly 30, and the position of the sliding block assembly 30 can be manipulated to bring the sliding block assembly 30 closer to the clamped object.

[0037] The sliding block assembly 30 includes a sliding connecting block 31, a first clamping block 32, an adjusting block 34, and a cylinder 35. The cylinder 35 is mounted on the adjusting block 34, the upper end of the elastic member 15 abuts against the adjusting block 34, and the lower end of the elastic member 15 abuts against the slider 14.

[0038] The piston rod of cylinder 35 is connected to sliding connecting block 31, and the first clamping block 32 is fixedly connected to sliding connecting block 31. Cylinder 35 can drive sliding connecting block 31 to move, so that after the sliding block assembly 30 is close to the object being clamped, the action of cylinder 35 will finally clamp the object being clamped. The first clamping block 32 is in direct contact with the object being clamped.

[0039] A first positioning element 33 is provided between the first clamping block 32 and the sliding connecting block 31. The first positioning element 33 cooperates with both the first clamping block 32 and the sliding connecting block 31 for positioning, thereby improving the positioning accuracy between the first clamping block 32 and the sliding connecting block 31. The first clamping block 32, as a force-bearing component, is in direct contact with the clamped object. Due to the provision of the first positioning element 33, it is not prone to displacement even under frequent force clamping, which greatly improves the positioning accuracy of the clamped component, thereby indirectly improving the processing accuracy of the clamped component.

[0040] The stop assembly 20 includes a positioning stop 21 and a second clamping block 22. The second clamping block 22 is fixedly installed on the positioning stop 21. A second positioning element 23 is provided between the second clamping block 22 and the positioning stop 21. Furthermore, a third positioning element 24 is provided between the positioning stop 21 and the base plate 10. The second positioning element 23 and the third positioning element 24 can improve the positioning accuracy, similar to the first positioning element 33. The first positioning element 33, the second positioning element 23, and the third positioning element 24 can be selectively provided, or all three can be provided.

[0041] The first positioning element 33, the second positioning element 23, and the third positioning element 24 can be positioning pins or other elements that can perform positioning functions. In this embodiment, the first positioning element 33, the second positioning element 23, and the third positioning element 24 are all positioning sleeves, and are respectively coaxially arranged with each bolt hole. The bolt holes are used to pass bolts to connect adjacent elements. For example, the first positioning element 33 is a positioning sleeve and is coaxially arranged with the first bolt hole, which is used to connect the first clamping block 32 and the sliding connecting block 31. The second positioning element 23 and the third positioning element 24 are similar. Since the first positioning element 33, the second positioning element 23, and the third positioning element 24 are all positioning sleeves and are coaxially arranged with the bolt holes, space is fully utilized for arrangement, making the overall structure more compact and simplifying the processing of positioning holes. The number of the first positioning element 33, the second positioning element 23, and the third positioning element 24 can be set to one or more, for example, at least two each, thereby further improving positioning accuracy.

[0042] In this embodiment, the sliding connecting block 31 is locked onto the guide slider 13. A guide rail 12 is mounted on the base plate 10, and the guide slider 13 slides along the guide rail 12, thereby improving the movement accuracy of the sliding connecting block 31 and further improving the positioning accuracy of the clamped component. In this embodiment, two guide sliders 13 and two guide rails 12 are provided, but this is not a limitation. The number of guide sliders 13 and guide rails 12 can be set according to actual conditions.

[0043] The pneumatic control assembly 40 includes a pressure regulating valve 41 and a manual control valve 42. The pressure regulating valve 41 and the manual control valve 42 are mounted on the tail of the cylinder 35 via an L-shaped mounting bracket 43. The pressure regulating valve 41 and the manual control valve 42 are mounted on the inner side of the L-shaped mounting bracket 43, which makes the overall air circuit cleaner, does not affect the operation process, and makes the overall device more compact.

[0044] In this embodiment, two sliders 14 and two slide grooves 16 are provided. Two guide rails 12 are located on the outer sides of the two slide grooves 16. A base plate mounting groove 17 is provided in the middle of the two slide grooves 16 for mounting and fixing the base plate 10 to the worktable. Compared with the traditional method of using clamps for fixing, this solution occupies less space. Especially when multiple positions are used simultaneously, such as... Figure 7 As shown, the overall layout is more compact, and the air passages are cleaner and more aesthetically pleasing.

[0045] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
