Example 1

Referring to fig. 1 to 4, the present embodiment provides a four-leg clamping mechanism for a machine tool, including a bottom plate 10 and a workpiece 30, a fixing rod 11 for fixing the position of the workpiece 30 is symmetrically welded on the upper surface of the bottom plate 10, and a clamping slot 12 for clamping the workpiece 30 is formed on the upper surface of the fixing rod 11, which aims to clamp both sides of the workpiece 30 and also to raise the height of the workpiece 30 by clamping the workpiece 30 in the clamping slot 12, so as to facilitate drilling of the workpiece 30, and a clamping assembly 20 for welding on the bottom plate 10 is symmetrically arranged on one side of the fixing rod 11, which aims to clamp the workpiece 30, so as to temporarily fix the position of the workpiece 30, wherein:

the clamping assembly 20 comprises a supporting column 21 and a pressing rod 22, wherein the pressing rod 22 is connected inside the supporting column 21 in a sliding mode, the purpose is to facilitate the upward movement of the pressing rod 22, for taking and placing of the workpiece 30, one end above the pressing rod 22 is connected with the fixing rod 11 in a rotating mode through a stabilizing rod 24, and the purpose is to fix the moving position of the pressing rod 22, so that the workpiece 30 is clamped in the clamping groove 12 of the fixing rod 11, and the phenomenon that the drilling efficiency is affected due to the fact that the workpiece 30 moves randomly is avoided.

The working principle is as follows: firstly, one end of the stabilizer bar 24 is pushed, the stabilizer bar 24 rotates anticlockwise, meanwhile, the pressing rod 22 moves upwards, then the workpiece 30 is placed between the two fixing rods 11, two sides of the workpiece 30 are fixed through the clamping grooves 12, the position of the workpiece 30 is stabilized, then the stabilizer bar 24 rotates clockwise, the pressing rod 22 is pressed downwards by the stabilizer bar 24 until the lower surface of one end of the pressing rod 22 is tightly attached to the upper surface of the workpiece 30, and therefore the workpiece 30 is temporarily fixed in position, at this moment, the workpiece 30 can be drilled, and the clamping work of the workpiece 30 can be completed.

In order to raise the pressing rod 22 upwards, an elastic member 23 is provided inside the supporting column 21 for connecting the other end of the pressing rod 22, and the purpose is to fix the stabilizing rod 24 inside the rod 11 by rotating the stabilizing rod 24 counterclockwise, and at this time, the pressing rod 22 is sprung upwards by the resilience of the elastic member 23, and the elastic member 23 is preferably a spring, and can also be an air bag to achieve the above purpose, thereby facilitating the operation of the clamping assembly 20 and improving the working efficiency.

Considering that stabilizer bar 24 does not facilitate the movement of stabilizer bar 24 when the longer ends of the upper surface of lever 22 are depressed during rotation, stabilizer bar 24 takes on an L-shape in which: the upper end of the stabilizer bar 24 is used for rotation, the lower end is used for connecting the fixing rod 11, and a backing plate 25 for raising the upper end of the stabilizer bar 24 is arranged below the upper end of the stabilizer bar 24, so that the rotation of the stabilizer bar 24 is facilitated, and the working speed is increased.

In order to facilitate the movement of the plunger 22, the plunger 22 therefore assumes an L-shape, in which: the lower end of the pressing rod 22 is used for connecting the elastic part 23 to move inside the supporting column 21, and the upper end of the pressing rod 22 is used for clamping the workpiece 30, so that the height of the pressing rod 22 can be adjusted, and the clamping effect can be realized.

When the four-leg clamping mechanism of the machine tool in the embodiment is used specifically, firstly, one end of the stabilizer bar 24 is pushed, the stabilizer bar 24 rotates anticlockwise, the press rod 22 is bounced upwards through the resilience force of the elastic piece 23, then the workpiece 30 is placed between the two fixing rods 11, two sides of the workpiece 30 are fixed through the clamping groove 12, the position of the workpiece 30 is stabilized, then the upper surface of the press rod 22 is pressed downwards firstly, then the stabilizer bar 24 rotates clockwise, the press rod 22 is pressed downwards through the stabilizer bar 24 until the lower surface of one end of the press rod 22 is tightly attached to the upper surface of the workpiece 30, so that the workpiece 30 is temporarily fixed in position, at the moment, the workpiece 30 can be drilled, and the clamping work of the workpiece 30 can be completed.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
