Description

Technical Field

[0001] The utility model relates to the technical field of bench vises, in particular to a bench vise with self-adaptive jaw adjustment. Background Art

[0002] Bench vise, also known as a vice or a vise, is a commonly used tool for fitters. It is usually installed on a workbench and is mainly used to clamp workpieces for assembly, repair and processing by fitters. There are many types of bench vises, which are divided into fixed and rotary types according to the fixing method. When using a bench vise, you need to ensure that it is firmly and safely mounted on the workbench, and adjust the clamping force according to the size and material of the workpiece. At the same time, you need to choose a suitable clamping position to avoid affecting the workpiece during the clamping process. Bench vise is usually equipped with different types of clamps, and you need to choose a suitable clamp according to the shape and size of the workpiece. In general, bench vise is an indispensable tool in a bench workshop, which can greatly improve work efficiency and processing accuracy. The jaws of the bench vise are a necessary structure for the bench vise to clamp the workpiece.

[0003] According to the patent with application number 202122619241.2, a bench vise is disclosed, including a base plate fixed on the top of a workbench, two support rods fixedly connected to the two ends of the top of the seat plate, two guide rods fixedly connected to the top of the seat plate, a lead screw with two ends rotatably connected to the two support rods, a sliding seat arranged on the two guide rods and capable of sliding on the two guide rods along the length direction of the seat plate, a clamping platform fixedly connected to the top of the sliding seat and the top of one of the support rods, and a clamping block arranged on the side where the two clamping platforms are close to each other.

[0004] By adopting the above scheme, the clamping block can be replaced conveniently and quickly after being damaged, so that it is not easy to affect the clamping accuracy or clamp the workpiece due to the damage of the clamping block. However, the above scheme still has certain defects when used. When the above scheme is used, the working surface of the jaws is a plane, which cannot be fitted with the surface of the irregular workpiece according to the actual situation, resulting in the clamping of the irregular workpiece being unreliable. If the workpiece is clamped forcibly, it is easy to cause damage to the surface or body of the workpiece. For this reason, we provide a bench vise with adaptively adjustable jaws to solve the above problems. Utility Model Content

[0025] The moving block 5 can slide on the inner wall of the moving groove 4, and can drive the jaw seat 6 to move, so that the jaw seat 6 on the right side can be moved closer to the jaw seat 6 on the left side, so as to facilitate clamping and fixing the workpiece.

[0026] The inner wall of the moving groove 4 is provided with two symmetrical sliding grooves 10 , and the inner walls of the two sliding grooves 10 are both slidably connected with a sliding block 11 , and the sliding block 11 is connected to the moving block 5 .

[0027] When the moving block 5 slides on the inner wall of the moving groove 4, it can drive the slider 11 to slide on the inner wall of the sliding groove 10, guide and limit the moving block 5, and ensure the stability of the moving block 5 when moving.

[0028] An adaptive component 7 is installed inside the two jaw seats 6. The adaptive component 7 includes a group of equidistantly arranged sealing cavities 701 and a group of equidistantly arranged ventilation grooves 702 opened inside the jaw seats 6. Every two sealing cavities 701 are connected through the ventilation grooves 702. The inner wall of each sealing cavity 701 is slidably connected with a piston plate 703. The piston plate 703 and the sealing cavity 701 are in a sealed state. A clamping column 704 is installed on the outer surface of each piston plate 703, and the end of the clamping column 704 away from the piston plate 703 passes through the inner wall of the sealing cavity 701 and extends to the outside of the sealing cavity 701. The penetration point of the clamping column 704 and the sealing cavity 701 is slidably connected.

[0029] When clamping and fixing an irregular workpiece, one of the rubber pads 705 first contacts the outer surface of the irregular workpiece, so that the piston plate 703 moves inside the sealing chamber 701, and the air inside the sealing chamber 701 enters the other sealing chambers 701 through the ventilation groove 702, so that the air inside the other sealing chambers 701 can push the piston plate 703 to move outward, and the other clamping columns 704 can extend to contact the outer surface of the irregular workpiece, so that the irregular workpiece can be clamped and fixed conveniently.

[0030] A rubber pad 705 is installed at one end of each clamping column 704 away from the piston plate 703 , and a group of anti-skid grooves 706 arranged at equal distances are formed on the outer surface of each rubber pad 705 .

[0031] The rubber pad 705 is connected to the clamping column 704 by screws. The provided rubber pad 705 and anti-slip groove 706 can increase the friction force at the end of the clamping column 704, thereby ensuring the clamping effect of the device on the workpiece.
