Description

Technical Field

[0001] This application relates to the field of vises, and in particular to bidirectional flexible vises. Background Technology

[0002] A bench vise is an essential tool for fitters, and the very reason for the name "fitter," as most of their work is done in a bench vise, such as sawing, filing, chiseling, and assembling and disassembling parts. Mounted on a workbench, the vise is standardized by the width of its jaws, with common sizes ranging from 75mm to 300mm. The purpose of a bench vise is to securely clamp workpieces on a workbench. When installing a bench vise, the working surface of the fixed jaws must be outside the edge of the workbench to ensure that the lower end of long, narrow workpieces is not obstructed by the edge. The center hole of the swivel base should face inwards to allow for better load distribution on the workbench and prevent damage. The ideal working height for the operator is when the jaws are level with the elbow, with the elbow resting at the highest point of the vise and the fist just touching the chin. The length and width of the workbench are determined by the specific work being done.

[0003] Existing bidirectional flexible vises have difficulty clamping two workpieces of different sizes at the same time, which reduces their applicability. Utility Model Content

[0004] To address the aforementioned issues, this application provides a bidirectional flexible vise.

[0005] The bidirectional flexible vise provided in this application adopts the following technical solution:

[0006] A bidirectional flexible vise includes a vise body. A groove is formed on the upper surface of the vise body. Two sliders are slidably connected within the groove. A fixing block is fixedly connected to one end of the groove. A bidirectional lead screw is provided within the groove. Both ends of the bidirectional lead screw pass through the sidewall of the groove and are respectively connected to the fixing block, forming a rotatable arrangement. Connecting blocks threaded onto the bidirectional lead screw are fixedly connected to the lower surface of each slider. A fixing sleeve is fixedly connected to one side of the fixing block within the groove. A movable sleeve is threadedly connected to the fixing sleeve. A limit block is fixedly connected to one end of the bidirectional lead screw passing through the fixing block. The limit block is slidably disposed within the movable sleeve. Abutment components are provided on the groove and the bidirectional lead screw to prevent movement of the bidirectional lead screw.

[0007] By adopting the above technical solution, in use, the fixed jaws are installed in the middle of the clamp body, and the movable jaws are installed on the sliders respectively. By rotating the bidirectional lead screw, the bidirectional lead screw drives the two connecting blocks to move closer to each other, and the two sliders drive the movable jaws to move closer to the fixed jaws to clamp the workpiece. When clamping two workpieces of different sizes, by rotating the movable sleeve, the movable sleeve moves within the fixed sleeve, pushing the limit block closer to the fixed block. The limit block drives the bidirectional lead screw to move, adjusting the distance between the two movable jaws and the fixed jaws. This allows for different distances between the two movable jaws and the fixed jaws, enabling the clamping of workpieces of different sizes. This avoids the problem of difficulty in clamping two workpieces of different sizes simultaneously, which reduces applicability.

[0008] Preferably, the abutting assembly includes a rotating disk rotatably connected to one side wall of the slide groove, a fixed disk is fixedly connected to one end of the bidirectional lead screw near the rotating disk, a spring is fixedly connected between the rotating disk and the fixed disk, and one end of the bidirectional lead screw passes through the rotating disk and forms a sliding arrangement.

[0009] By adopting the above technical solution, when the limiting block is brought close to the fixed block, the spring contracts. When the limiting block moves away from the fixed block, the spring rebounds and the limiting block is pressed against the moving sleeve, preventing the limiting block from moving between the moving sleeve and the fixed block, thus preventing the bidirectional lead screw from moving.

[0010] Preferably, the sidewalls of the slide groove are provided with limiting grooves, and the sidewalls of the slider are respectively slidably disposed in the limiting grooves.

[0011] By adopting the above technical solution, the limiting groove can improve the stability of the slider sliding in the groove and prevent the slider from shaking.

[0012] Preferably, a first dustproof plate is fixedly connected to both ends of the slide groove below the limiting groove, and a second dustproof plate is fixedly connected between the two first dustproof plates inside the slide groove. Both the first dustproof plate and the second dustproof plate are located on the lower surface of the slider.

[0013] By adopting the above technical solution, when the connecting block drives the slider to move, the two ends of the lower surface of the slider are continuously in contact with the first dustproof plate and the second dustproof plate to block the slide groove, which can prevent dust and other debris from falling into the slide groove and affecting the bidirectional lead screw.

[0014] Preferably, a connecting shaft is fixedly connected to the side wall of the limiting block away from the bidirectional lead screw, and the end of the connecting shaft away from the limiting block passes through the movable sleeve and is fixedly connected to a knob.

[0015] By adopting the above technical solution, the toggle handle can be used to easily drive the bidirectional lead screw to rotate, so that the slider can move in the groove.

[0016] Preferably, the end of the movable sleeve away from the fixed block has a plurality of annular arrayed rotating holes.

[0017] By adopting the above technical solution, the rotating hole allows for easy rotation of the movable sleeve using external tools, enabling the movable sleeve to move within the fixed sleeve and drive the bidirectional lead screw to move.

[0018] Preferably, the upper surface of the slider and the upper surface of the clamp body are provided with a plurality of mounting holes for mounting the moving jaws and the fixed jaws.

[0019] By adopting the above technical solution, the moving jaws and fixed jaws can be easily installed on the slider or jaw body through the mounting holes.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the cooperative arrangement of structures such as a fixed block, a fixed sleeve, and a movable sleeve. In use, the fixed jaws are installed in the middle of the clamp body, and the movable jaws are respectively installed on the sliders. By rotating the bidirectional lead screw, the bidirectional lead screw drives the two connecting blocks closer to each other, causing the two sliders to move the movable jaws closer to the fixed jaws, thus clamping the workpiece. When clamping two workpieces of different sizes, by rotating the movable sleeve, the movable sleeve moves within the fixed sleeve, pushing the limiting block closer to the fixed block. The limiting block then drives the bidirectional lead screw to move, adjusting the distance between the two movable jaws and the fixed jaws. This allows for different distances between the two movable jaws and the fixed jaws, enabling the clamping of workpieces of different sizes. This avoids the problem of difficulty in simultaneously clamping two workpieces of different sizes, which reduces applicability.

[0022] 2. By using the first and second dustproof plates, when the connecting block drives the slider to move, the two ends of the lower surface of the slider are continuously in contact with the first and second dustproof plates, which shields the slide groove and prevents dust and other debris from falling into the slide groove and affecting the bidirectional lead screw.

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a bidirectional flexible vise.

[0030] Reference Figure 2 , Figure 3 and Figure 4 A bidirectional flexible vise includes a vise body 1. A groove 2 is provided on the upper surface of the vise body 1. Two sliders 3 are slidably connected in the groove 2. A moving component for driving the sliders 3 to slide is provided in the groove 2. The moving component includes a fixed block 4, a bidirectional lead screw 5 and a connecting block 6.

[0031] The fixed block 4 is fixedly connected inside the slide groove 2. The bidirectional screw 5 is set inside the slide groove 2. The two ends of the bidirectional screw 5 pass through the side wall of the slide groove 2 and the fixed block 4 respectively, forming a rotatable arrangement. There are two connecting blocks 6, which are fixedly connected to the lower surface of the slider 3 and threadedly connected to the bidirectional screw 5. A fixed sleeve 7 is fixedly connected to one side of the fixed block 4 inside the slide groove 2. A movable sleeve 8 is threadedly connected inside the fixed sleeve 7. A limit block 9 is fixedly connected to one end of the bidirectional screw 5 that passes through the fixed block 4. The limit block 9 is slidably set inside the movable sleeve 8. The slide groove 2 and the bidirectional screw 5 are provided with abutment components to prevent the bidirectional screw 5 from moving.

[0032] Reference Figure 3 The abutting component includes a rotating disk 10 rotatably connected to one side wall of the slide groove 2. A fixed disk 11 is fixedly connected to one end of the bidirectional lead screw 5 near the rotating disk 10. A spring 12 is fixedly connected between the rotating disk 10 and the fixed disk 11. One end of the bidirectional lead screw 5 passes through the rotating disk 10 and forms a sliding arrangement. When the limiting block 9 is brought close to the fixed block 4, the spring 12 is contracted. When the limiting block 9 is moved away from the fixed block 4, the spring 12 rebounds and can abut the limiting block 9 in the moving sleeve 8, preventing the limiting block 9 from moving between the moving sleeve 8 and the fixed block 4, which would cause the bidirectional lead screw 5 to move.

[0033] Reference Figure 1 and Figure 2 Limiting grooves 19 are provided on both sides of the slide groove 2. The two sides of the slider 3 are slidably disposed in the limiting grooves 19. The limiting grooves 19 can improve the stability of the slider 3 sliding in the slide groove 2 and prevent the slider 3 from shaking.

[0034] Reference Figure 1 The two ends of the slide groove 2 are fixedly connected to the first dustproof plate 13 below the limiting groove 19. The two ends of the slide groove 2 are fixedly connected to the second dustproof plate 14 between the two first dustproof plates 13. The first dustproof plate 13 and the second dustproof plate 14 are both located on the lower surface of the slider 3. When the connecting block 6 drives the slider 3 to move, the two ends of the lower surface of the slider 3 are continuously in contact with the first dustproof plate 13 and the second dustproof plate 14 to block the slide groove 2 and prevent dust and other debris from falling into the slide groove 2 and affecting the bidirectional lead screw 5.

[0035] Reference Figure 3 and Figure 4 A connecting shaft 15 is fixedly connected to the side wall of the limiting block 9 away from the bidirectional lead screw 5. The end of the connecting shaft 15 away from the limiting block 9 passes through the movable sleeve 8 and is fixedly connected to the handle 16. The handle 16 facilitates the rotation of the bidirectional lead screw 5, so that the slider 3 moves in the slide groove 2.

[0036] Reference Figure 4 The movable sleeve 8 has multiple annular array rotating holes 17 at the end away from the fixed block 4. Through the rotating holes 17, it is convenient to use external tools to rotate the movable sleeve 8, so that the movable sleeve 8 can move in the fixed sleeve 7 and drive the bidirectional lead screw 5 to move.

[0037] Reference Figure 1 The upper surface of the slider 3 and the upper surface of the clamp body 1 are provided with multiple mounting holes 18 for mounting the moving jaws and the fixed jaws. The moving jaws and the fixed jaws can be easily mounted on the slider 3 or the clamp body 1 through the mounting holes 18.

[0038] The implementation principle of the bidirectional flexible vise in this embodiment is as follows: In use, the fixed jaws are installed in the middle of the vise body 1, and the movable jaws are respectively installed on the sliders 3. The bidirectional lead screw 5 is rotated via the knob 16, causing the two connecting blocks 6 to move closer together. This causes the two sliders 3 to move the movable jaws closer to the fixed jaws, clamping the workpiece. When clamping two workpieces of different sizes, the movable sleeve 8 is rotated via the rotating hole 17, causing the movable sleeve 8 to move within the fixed sleeve 7. This pushes the limiting block 9 closer to the fixed block 4, causing the limiting block 9 to move the bidirectional lead screw 5, adjusting the two... The distance between the moving jaws and the fixed jaws is adjusted so that the distances between the two moving jaws and the fixed jaws are different, allowing for the clamping of workpieces of different sizes. At the same time, when the limiting block 9 is brought close to the fixed block 4, the spring 12 contracts. When the limiting block 9 moves away from the fixed block 4, the spring 12 rebounds and abuts the limiting block 9 inside the moving sleeve 8, preventing the limiting block 9 from moving between the moving sleeve 8 and the fixed block 4, which would cause the bidirectional lead screw 5 to move. This minimizes the problem of difficulty in clamping two workpieces of different sizes at the same time, thus avoiding the problem of reduced applicability.

[0039] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
