Description

Technical Field

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

[0002] A bench vise is a general-purpose clamping tool used to hold workpieces. It is usually mounted on a workbench and is an essential tool in a fitter's workshop. It is used to hold various metal workpieces for fitter operations such as sawing, filing, drilling, and tapping, keeping the workpiece stable during processing. In woodworking, bench vises are often used to process wood and other materials.

[0003] A search revealed that the announcement number is CN215318127U, and the name is "A Multifunctional Bench Vise". It includes movable jaws, vertical ribs, and guide rods. Research and analysis showed that the integrated structure reduces casting defects, improves the yield of castings, and reduces casting costs. By setting V-grooves on the fixed jaws, the clamping function of the jaws for round parts is increased. However, it still has the following disadvantages to some extent.

[0004] For example, while the V-grooves can clamp round parts, when clamping square wood, the multiple V-grooves in different directions will reduce the clamping force on the wood, causing it to loosen. At the same time, it is inconvenient to replace the clamping parts according to the needs, and it cannot adapt to workpieces other than round and square, thus having a limited range of applications. Using special equipment will also increase costs. In order to solve the above technical problems, we have designed a bench vise for woodworking. Utility Model Content

[0005] The purpose of this utility model is to provide a bench vise for woodworking, which has the advantages of easy adjustment and replacement of clamping parts. It solves the problems that when clamping square wood, the multiple V-grooves in different directions will reduce the clamping force on the wood, causing the wood to loosen. At the same time, it is inconvenient to replace the clamping parts according to the needs, and it cannot adapt to workpieces other than round and square, thus having a limited range of applications.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bench vise for woodworking, comprising a mounting plate, a mounting bracket fixedly welded to the left side of the bottom of the mounting plate, a bolt 1 installed at the bottom of the mounting bracket, a mounting seat fixedly welded to the top of the mounting plate, a rotating column penetrating through the inner cavity of the mounting seat, bolts 2 installed on both the front and rear sides of the mounting seat, a threaded ring fixedly welded to the left end of the rotating column, and movable through holes penetrating the left sides of both the front and rear sides of the rotating column, a clamping assembly fixedly mounted on the surface of the rotating column, the clamping assembly comprising a fixed clamping plate and a threaded column, the fixed clamping plate fixedly sleeved on the right side of the surface of the rotating column, the threaded column threadedly connected to the inner cavity of the threaded ring, the right end of the threaded column penetrating into the inner cavity of the rotating column and rotatably connected to a connecting slider via a bearing, a movable clamping plate sleeved on the left side of the surface of the rotating column, upper clamping blocks installed on the top left side of the fixed clamping plate and the top right side of the movable clamping plate, and lower clamping blocks installed on the bottom left side of the fixed clamping plate and the bottom right side of the movable clamping plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides two sets of different upper and lower clamping blocks above and below the fixed and movable clamping plates. The two types of clamping blocks can adapt to square and round timber respectively. By rotating the column inside the mounting base, the upper and lower clamping blocks can be interchanged. Then, the rotating column is fixed with bolts, allowing workers to quickly switch the appropriate clamping blocks according to the timber requirements.

[0015] 2. This utility model uses the rotation of the threaded column and the threaded action with the threaded ring to drive the connecting slider to move, so that the moving clamping plate moves to the side of the fixed clamping plate, thereby causing the clamping blocks on both sides to move towards each other and clamp the wood, achieving a fast clamping effect. It can effectively ensure that the wood will not slip during processing, and the upper and lower clamping blocks can be disassembled and replaced from the mounting groove through the mounting block as needed, which can adapt to wood of different shapes.

[0022] Please see Figures 1-5A bench vise for woodworking includes a mounting plate 1. A mounting bracket 2 is fixedly welded to the left side of the bottom of the mounting plate 1. A bolt 3 is installed at the bottom of the mounting bracket 2. A mounting seat 8 is fixedly welded to the top of the mounting plate 1. A rotating column 5 is provided through the inner cavity of the mounting seat 8. Bolts 4 are installed on both the front and rear sides of the mounting seat 8. A threaded ring 7 is fixedly welded to the left end of the rotating column 5. By setting the threaded ring 7, the threaded column 64 can move inside the rotating column 5 under the action of the thread. A moving through hole 9 is provided through the left side of both the front and rear sides of the rotating column 5. By setting the moving through hole 9, a connecting slider 68 can be connected to a moving clamping plate 63 from the inside, thereby driving the moving clamping plate 63 to move through its own movement. A clamping assembly 6 is fixedly installed on the surface of the rotating column 5. The clamping assembly 6 includes a fixed clamping plate 61 and the threaded column 6. 4. The fixed clamping plate 61 is fixedly sleeved on the right side of the surface of the rotating column 5. The threaded column 64 is threadedly connected to the inner cavity of the threaded ring 7. The right end of the threaded column 64 passes through the inner cavity of the rotating column 5 and is rotatably connected to the connecting slider 68 through the bearing. After the connecting slider 68 passes through the movable through hole 9 and is connected to the movable clamping plate 63, it can ensure the stability of the movement of the movable clamping plate 63 and limit the connecting slider 68. Through the bearing movable connection between it and the threaded column 64, the threaded column 64 will not drive the connecting slider 68 to rotate together during the rotation, but can move together with the threaded column 64. The movable clamping plate 63 is sleeved and installed on the left side of the surface of the rotating column 5. The top left side of the fixed clamping plate 61 and the top right side of the movable clamping plate 63 are both equipped with upper clamping blocks 65. The bottom left side of the fixed clamping plate 61 and the bottom right side of the movable clamping plate 63 are both equipped with lower clamping blocks 62.

[0023] Please see Figure 1 and Figure 2 The surface of bolt 3 is threadedly connected to the bottom of mounting bracket 2. A rotating handle is fixedly welded to the bottom of bolt 3. The rotating handle allows the worker to easily rotate bolt 3 and press it against the workbench. The mounting plate 1 and mounting bracket 2 are then used to fix the device in the installation position.

[0024] Please see Figure 1 , Figure 4 and Figure 5 A faceted groove 10 is provided on the right side of the surface of the rotating column 5. By setting the faceted groove 10, the mating surface of the bolt 2 4 can be made flat, which can stably mat the rotating column 5 and prevent it from rotating. The connection between the surface of the bolt 2 4 and the mounting base 8 is threaded. One end of the bolt 2 4 penetrates into the inner cavity of the mounting base 8 and is in close contact with the surface of the faceted groove 10. The other end of the bolt 2 4 is fixedly welded with a rotating handle 2. The rotating handle 2 allows the worker to easily rotate the bolt 2 4, thereby enabling the bolt 2 4 to firmly mat the rotating column 5.

[0025] Please see Figure 4 and Figure 5 A cavity is provided on the left side of the inner cavity of the rotating column 5. A rotating handle 3 is fixedly welded to the left end of the threaded column 64. The rotating handle 3 allows the worker to easily rotate the threaded column 64, thereby easily controlling the moving clamp 63 to move towards the fixed clamp 61, achieving the effect of saving physical strength and making it easier for the worker to fix the workpiece. The surface of the connecting slider 68 is in sliding contact with the inner wall of the cavity. The front and rear sides of the connecting slider 68 are both through the moving through hole 9 and fixedly connected to the inner wall of the moving clamp 63.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The upper clamping block 65 has anti-slip grooves on its opposite side. By setting anti-slip grooves, the friction when in contact with the workpiece can be increased, ensuring that the upper clamping block 65 can stably clamp the workpiece. The top and bottom of the opposite side of the lower clamping block 62 are fixedly connected with semi-circular protrusion structures. The semi-circular protrusion structures can limit the circular wood. When the lower clamping block 62 clamps the wood, the four semi-circular protrusion structures are used to clamp the surface of the wood to achieve a stable clamping effect and prevent the pipe from rotating.

[0027] Please see Figure 4 and Figure 5 Mounting slots 66 are provided on the top and bottom of the left side of the fixed clamping plate 61 and the top and bottom of the right side of the movable clamping plate 63. Mounting blocks 67 are fixedly connected to the side of the upper clamping block 65 and the lower clamping block 62 near the mounting slots 66.

[0028] Please see Figure 4 and Figure 5 The front side of the mounting groove 66 is an open structure, and the rear side of the mounting groove 66 is a closed structure. Both the mounting groove 66 and the mounting block 67 are "T" shaped structures. The surface of the mounting block 67 matches the inner wall of the mounting groove 66. By setting the mounting groove 66 and the mounting block 67, the upper clamping block 65 and the lower clamping block 62 can be easily replaced. The appropriate size of the fixture can be customized to clamp the workpiece according to the requirements, thereby improving the clamping adaptability.

[0029] In use, place the mounting plate 1 on top of the edge of the worktable, so that the mounting bracket 2 is below the worktable. Then tighten bolt 3 so that its top is pressed against the bottom of the worktable, thus fixing the mounting plate 1 to the worktable. Then select the appropriate clamping block according to the type of board to be fixed. When processing square timber, there is no need to adjust the position of the clamping block. Figure 1 and Figure 2As shown in the diagram; when processing round timber, loosen bolt 24 to separate it from the rotating column 5, then rotate the rotating column 5 half-shaft so that the lower clamping block 62 rotates to the position of the original upper clamping block 65. At this time, tighten bolt 24 so that it abuts against the cut groove 10 on the surface of the rotating column 5, thereby preventing the rotating column 5 from continuing to rotate. After adjustment, place the timber between the upper clamping blocks, then rotate the threaded column 64. Using the thread action with the threaded ring 7, drive the connecting slider 68 to move, thereby driving the moving clamping plate 63 to move towards the fixed clamping plate 61. This causes the clamping blocks on both sides to move towards each other and clamp the timber, achieving a fixing effect. When it is necessary to replace the upper clamping block 62 and the lower clamping block 65, pull the upper clamping block 62 and the lower clamping block 65 forward to remove the mounting block 67 from the inside of the mounting groove 66. Then replace it with a custom clamping block that matches the shape of the timber, and then fix it inside the mounting groove 66 through the mounting block 67 to achieve the replacement effect.

[0030] In summary, this bench vise for woodworking, through the cooperation of bolt 3, bolt 4, rotating column 5, clamping assembly 6, threaded ring 7, and mounting base 8, solves the problems of reduced clamping force and loosening of square timber caused by multiple V-grooves, inconvenience in replacing clamping components as needed, and limited applicability to workpieces other than round and square.
