DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Combination Figure 1As shown, a support mechanism for increasing the workpiece clamping capacity of a bench vise jaws includes a horizontal fixed hanger plate 1, and a first contact piece 2 and a second contact piece 3 are fixedly connected to the lower middle end of the fixed hanger plate 1. In the present embodiment, the first contact piece 2 is a polyurethane block, and the second contact piece 3 is a steel plate 5. The first contact piece 2 and the second contact piece 3 are fixed together, and the sum of the thicknesses of the two contact pieces is less than the width of the fixed hanger plate 1, so as to avoid interference when the fixed hanger plate 1 clamps a higher workpiece. The two contact pieces are used to abut between two side-by-side workpieces, and the polyurethane block undergoes elastic deformation when pressed, which can effectively clamp the workpiece, and also ensures the stable clamping of the side-by-side workpieces, effectively solving the problem of bulge in the middle when tightening side by side.

[0025] Combination Figure 2 , Figure 3 As shown, an extension piece 12 is connected below both ends of the fixed hanging plate 1 through a height adjustment component 4 (i.e., a stud and a nut), and the other end of the extension piece 12 is fixedly connected to the sliding sleeve 6. The first fixed seat 8 and the second fixed seat 9 are fixedly connected through a connecting plate 10, and an opening 11 is provided in the middle of the connecting plate 10. The lower end of the height adjustment component 4 is fixedly connected to the sliding sleeve 6 through the extension piece 12, and the extension piece 12 passes through the opening 11 in the middle of the connecting plate 10.

[0026] A support shaft 7 is slidably connected inside the sliding sleeve 6 , and two ends of the support shaft 7 are fixedly connected to a first fixing seat 8 and a second fixing seat 9 respectively.

[0027] The two first fixed seats 8 are fixedly connected by a plate 5 to keep the two ends of the fixed hanger plate 1 relatively stable, enhance the frame strength of the entire mechanism, and avoid deformation of the fixed hanger plate 1 and the first contact piece 2 and the second contact piece 3. Through holes are provided on the first fixed seat 8 and the second fixed seat 9, which are convenient for using fasteners to fix the first fixed seat 8 and the second fixed seat 9 on the vise frame.

[0028] In this embodiment, the sliding sleeve 6 is preferably a linear bearing, and the surface of the support shaft 7 is polished to enable the fixed hanging plate 1 to move more smoothly relative to the support shaft 7.

[0029] When the sliding sleeve 6 moves to the side close to the plate 5, the side surface of the first contact member 2 is higher than the plate 5, so as to prevent the plate 5 from interfering with the clamping of the workpiece.

[0030] The height adjustment assembly 4 includes an adjustment rod 401 and a stopper 402 . The lower end of the adjustment rod 401 is slidable up and down and connected to the sliding sleeve 6 . The relative positions of the adjustment rod 401 and the sliding sleeve 6 are kept unchanged by the stopper 402 .

[0031] The adjusting rod 401 is a stud, and the limiting member 402 is a nut. The upper end of the stud cooperates with the nut to fix it on the fixed hanging plate 1, and the lower end of the stud cooperates with the nut to connect it to the sliding sleeve 6 in a height-adjustable manner.

[0032] When the utility model is implemented, the first contact member 2 and the second contact member 3 are placed between two parallel workpieces to be clamped, the second contact member 3 is close to the fixed end of the vise jaws, and the first contact member 2 is close to the movable end of the vise jaws. After the vise is pre-tightened to clamp the workpieces, the first fixed seat 8 and the second fixed seat 9 are fixed on the vise frame.

[0033] Adjust the clamping force of the vise to clamp the two workpieces. Avoid over-clamping to avoid excessive deformation of the polyurethane block. Then process the workpieces.

[0034] When the clamping height needs to be adjusted, the lower limiting member 402 (ie, the nut) is rotated counterclockwise to raise the fixed hanging plate 1. Similarly, the lower limiting member 402 can be rotated clockwise to lower the height of the fixed hanging plate 1, thereby adjusting the two contact members.

[0035] When replacing the workpiece, first loosen the bench vise, take out the processed workpiece, and then put the two workpieces in order. The horizontally movable fixed hanging plate 1 is convenient for leaving a loading gap when clamping the workpiece. After loading, clamp the bench vise.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
