What the utility model aims to solve is the single-function problem of the existing clamping device in processing, and provides a clamping method with more complete functions, convenient use and simpler structure.

In order to achieve the above object, the utility model provides a multifunctional clamping device, including a base, which is characterized in that two guide rails parallel to each other are respectively provided on both sides of the base, and one end of one guide rail is fixedly arranged There is a main column, and the guide rail is equipped with a secondary column 1 that can move along the direction of the guide rail; the other guide rail is equipped with 2 secondary column 2 that can move along the direction of the guide rail; the main column and the secondary column 2 that is close to it On the upper side, as well as on the first auxiliary column and the second auxiliary column adjacent to it, mutually cooperating clamping structures are respectively provided.

Preferably, the clamping structure is two V-shaped jaws with opposite openings, and one of the V-shaped jaws can move along a horizontal plane and in a direction perpendicular to the guide rail.

Further, a ball lock is provided on the contact surface between the V-shaped jaw and the workpiece.

Preferably, the clamping structure is two mutually matching rectangular jaws, one of which can move along the horizontal plane and in a direction perpendicular to the guide rail.

The ball blocks are installed on the V-shaped jaws. When the ball blocks need to be installed, one ball block can be installed on the top and bottom of each V-shaped jaw. The ball blocks are installed in the form of threads. When the installation is not required, the ball block can be removed.

The utility model can realize the clamping of various workpieces, and can also realize the function that the workpieces can still be rotated after clamping the tubular workpieces. The device can adapt to the clamping of various workpieces by changing the jaws, and the use of the ball block also increases the function of rotating the tubular object. The utility model provides new convenience, reasonable and concise structure, convenient operation, long service life, strong practicability, and has broad application prospects.

Detailed ways

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

Example

As shown in Figure 1-4, the structure diagram of the multifunctional clamping device provided by the utility model includes a base 8, two sides of the base 8 are respectively provided with two guide rails 5 parallel to each other, and one of the guide rails 5 One end is fixed with a main column 1, and the guide rail 5 is provided with a secondary column 1 21 that can move along the direction of the guide rail 5; the other guide rail 5 is provided with 2 secondary columns 2 2 that can move along the direction of the guide rail 5 The main column 1 and the secondary column 22 close to it, as well as the secondary column 1 21 and the secondary column 22 close to it are provided with clamping structures that cooperate with each other. The clamping structure is two V-shaped jaws 3 with opposite openings, and one of the V-shaped jaws 3 can move along the horizontal plane and in the direction perpendicular to the guide rail 5, which is realized by passing through the shaft pin 9 of the second auxiliary column 22 , A handle 4 is installed at the end of the shaft pin 9, which is convenient for holding. A ball fast 6 is arranged on the contact surface between the V-shaped jaw 3 and the workpiece. After adjusting the positions of main column 1, auxiliary column one 21, and auxiliary column two 22, advancing the V-shaped jaw 3 can realize the clamping of the tubular workpiece. Ball blocks 6 can be installed on the upper and lower sides of the opening of the V-shaped jaw 3, and the tubular workpiece can rotate after the ball blocks 6 are installed. Secondary column one 21 and two secondary column two 22 are installed on two guide rails 5 respectively, can realize the adjustment of position. Axle pin 9 adopts cylindrical pin, and when turning handle 4, V-shaped jaw 3 can not rotate. The ball block 6 is installed on the contact surface between the V-shaped jaw 3 and the tubular workpiece. When the ball block 6 needs to be installed, a ball block 6 can be installed on the top and bottom of each V-shaped jaw 3. The ball block 6 is threaded. It can be installed in the form, and can be removed when it is not required to be installed.

V-shaped jaw 3 is installed on main column 1 and auxiliary column one 21, auxiliary column two 22, and the V-shaped jaw 3 on main column 1 and auxiliary column one 21 is fixedly installed. The V-shaped jaws 3 on the two secondary columns 22 can realize feeding after installation. Move the two secondary columns 22 to the positions corresponding to the main column 1 and the secondary column 1 21, place the tubular workpiece between the V-shaped jaws 3, turn the handle 4, drive the shaft pin 9, and push the V-shaped jaws 3 , and clamp the workpiece, as shown in Figure 6.

The clamping structure can also adopt two mutually matching rectangular jaws 7, as shown in FIG. The rectangular jaw 7 can realize the clamping of workpieces such as flat parts.

When the utility model is in use, first select the required jaw shape, and the jaw is installed on the four columns, if it is a V-shaped jaw 3, it should be selected whether the ball block 6 needs to be installed. Adjust the distribution position of auxiliary column one 21 and auxiliary column two 22 by guide rail 5 again, and fix. Put the workpiece to be clamped, and turn the handle 4 to realize the clamping of the workpiece. If you want to clamp workpieces such as flat pieces, you can unload the V-shaped jaw 3 and replace it with a rectangular jaw 7.
