Description

Intelligent bench vise based on hydraulic system

technical field

The invention relates to the technical field of fitter clamps, in particular to an intelligent bench vise based on a hydraulic system.

Background technique

Bench vise is a commonly used clamping workpiece in the field of mechanical processing. It usually includes a base, a clamp body, a fixed jaw, a movable jaw and a screw. During the application process, the screw is turned to adjust the gap between the movable jaw and the fixed jaw. The distance to achieve workpiece clamping.

At present, the commonly used bench vise requires manual operation, and the screw rod is driven to rotate by turning the handle, so that the jaw screwed on the screw rod moves closer to the other jaw to realize the clamping and fixing function. The above-mentioned manual operation is inefficient and cannot accurately control the clamping force between the two jaws, which seriously affects the processing speed and quality of the workpiece.

Contents of the invention

The invention proposes an intelligent bench vise based on a hydraulic system, which can solve the problems of low clamping efficiency and inability to accurately control clamping force of existing bench vise equipment.

In order to achieve the above-mentioned technical purpose and achieve technical effects, the present invention solves the above-mentioned problems through the following technical solutions:

The intelligent bench vise based on the hydraulic system includes a bottom plate, a fixed tong body and a movable tong body arranged on the bottom plate, a guide chute is provided on the upper surface of the bottom plate, and a hydraulic cylinder and a fixed tong are respectively fixedly connected to the two ends of the guide chute body; the movable tong body is connected with the piston rod of the hydraulic cylinder, and is slidably connected in the guide chute; the guide shaft in the same direction as the movable tong body is set in the guide chute, and the bottom of the movable tong body is provided for guiding A through hole through which the shaft passes; jaws are provided on the gripping surfaces of the fixed tong body and the movable tong body.

In the above solution, the movable tong body is driven to slide in the guide chute through the movement of the hydraulic cylinder piston, and then the jaws of the moving fixed tong body and the movable tong body move toward each other to clamp the workpiece. Through the cooperation of the guide chute and the guide shaft, a better guiding effect can be achieved to ensure the smooth operation of the pliers.

In order to be suitable for clamping workpieces with different structures and improve the practicability of the device, cross V-shaped grooves are provided on the opposite contact surfaces of the jaws.

Further, for the disassembly and replacement of the surface and the jaws, the jaws are detachably connected to the fixed jaw body and the movable jaw body through threaded fasteners, and the gripping surfaces of the jaws, the fixed jaw body, and the movable jaw body are set corresponding screw holes.

In order to control the movement of the movable tong body through the liquid-driven piston, the piston rod of the hydraulic cylinder is rigidly connected to the movable tong body, and the cylinder body is provided with an oil inlet and an oil outlet. The expansion and contraction of the piston rod is controlled by controlling the oil flow at the inlet and outlet, and then the smooth and efficient reciprocation of the movable clamp body is controlled.

Advantage and effect of the present invention are:

1. The present invention replaces manual operation by setting a hydraulic cylinder, controls the expansion and contraction of the piston rod by controlling the oil flow at the inlet and outlet, and drives the movable clamp body to slide in the guide chute through the piston rod, so that the control is more stable and efficient;

2. Through the dual guidance of the guide chute and the guide shaft, it is beneficial to improve the stability of the movement of the movable clamp body;

3. The jaws can be detachably mounted on the body of the jaws, and cross-shaped V-shaped grooves with better adaptability are provided on the opposite contact surfaces of the jaws, which are beneficial to improving the gripping adaptability of the device and improving the clamping efficiency.

detailed description

The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

The intelligent bench vise based on the hydraulic system described in this embodiment, its main body includes a bottom plate 1 with a guide chute 4, a fixed tong body 2 fixed to one end of the guide chute 4 by threaded fasteners, and a sliding connection to the groove The movable clamp body 3 inside; the movable clamp body 3 is connected with the hydraulic cylinder 5 that is arranged on the other end of the guide chute 4, as shown in accompanying drawing 1.

The middle part of the guide chute 4 is provided with a guide shaft 6 arranged along the moving direction of the movable tong body 3 , and the bottom of the movable tong body 3 is provided with a through hole to cooperate with the guide shaft 6 to be fixed on the guide chute 4 . Jaws 7 are provided on the opposite surface of the movable clamp body 3 and the fixed clamp body 2, and the jaws 7 are still connected with the movable clamp body 3 and the fixed clamp body 2 by means of screws, which is convenient for disassembly and replacement; the relative contact of the jaws 7 Offer cross V-shaped groove 7-1 on the face, can further improve the scope of application of device, as shown in accompanying drawing 1.

The hydraulic cylinder 5 described in the embodiment is a single-rod hydraulic cylinder, including a piston rod 5-1, an oil outlet 5-2, a cylinder body 5-3, and an oil inlet 5-4. The cylinder body 5-3 cooperates with the top hole of the guide chute 4 through the threaded hole at the bottom to fix the hydraulic cylinder 6 on the guide chute 4, and the piston rod 5-1 is rigidly connected with the movable clamp body 3 to control the oil inlet 5- 4. The oil flow at the oil outlet 5-2 causes the piston rod 5-1 to do telescopic movement, so that the distance between the movable tong body 3 and the fixed tong body 2 changes, and the purpose of controlling the clamping force of the jaw 7 is achieved . The structure has no transmission gap, the speed of movement can be adjusted and controlled, and it runs smoothly, reducing manual intervention, which can further improve work efficiency and realize intelligence.

The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and modifications to these embodiments still fall within the protection scope of the present invention.
