Embodiment 1

[0029] Embodiment one, see appendix figure 1 - attached Figure 8 , the embodiment of the present invention provides an adjustable clamp, including a mounting frame 2, a fixing part 3, a chuck 4 and a rotating part 5; the fixing part 3 is fixedly connected to the first end of the mounting frame 2; the chuck 4 can be slidably set On the first end of the fixed part 3; the rotating part 5 is rotatably arranged on the mounting frame 2, and the rotating part 5 is arranged close to the second end of the fixing part 3, and the rotating part 5 is driven and connected with the chuck 4, and the rotating part is adjusted by rotation 5. The chuck 4 can slide on the fixing part 3.

[0030] In this embodiment, the mounting frame 2 can be installed on a machine tool, such as a lathe, a drilling machine, etc., and the parts to be processed can be fixed through the chuck 4, so as to meet its processing requirements. The chuck 4 is a prior art, and will not be repeated here. repeat. The fixi...

Embodiment 2

[0044] Embodiment 2, only the differences from Embodiment 1 will be described in detail below in conjunction with the accompanying drawings.

[0045] See attached Image 6 , in this embodiment, in order to make the driving groove 51 drive the driving member 6 more smoothly and conveniently, the driving groove 51 is designed as a heart-shaped structure, and the driving groove 51 includes a first driving part and a second driving part arranged symmetrically to each other The distance from each position on the first driving part to the rotation center of the rotating member 5 is different, and the distance from one end to the other end of the first driving part to the rotating center of the rotating member 5 increases or decreases gradually.

[0046] In this embodiment, when the scale pointer on the chuck 4 indicates the initial state at the zero scale line of the scale value of the fixed part 3, one end of the drive part 6 extending into the drive groove 51 is placed in the firs...

Embodiment 3

[0049] Embodiment 3, only the differences from Embodiment 1 will be described in detail below in conjunction with the accompanying drawings.

[0050] See attached Figure 7 , in this embodiment, in order to make the driving groove 51 drive the driving member 6 more smoothly and conveniently, the driving groove 51 is designed in an elliptical structure.

[0051] In this embodiment, when the scale pointer on the chuck 4 indicates the initial state at the zero scale line of the fixed member 3 scale value, the end of the drive member 6 extending into the drive groove 51 is placed at the corresponding position of the small diameter of the ellipse, and then passes By adjusting the rotation of the rotating member 5, the eccentricity of the parts to be processed can be increased, then decreased, and increased again, so as to realize the adjustment of different eccentricities of the parts to be processed. Simultaneously, it is a process of gradually increasing from the small diameter ...

Abstract

The invention relates to the technical field of mechanical processing, in particular to an adjustable fixture, comprising a mounting frame, a fixing part, a chuck and a rotating part; the fixing part is fixedly connected to the first end of the mounting frame; the chuck is slidably arranged on the fixing part On the first end of the first end; the rotating part can be rotatably arranged on the mounting frame, and the rotating part is arranged close to the second end of the fixed part, and the rotating part is connected to the chuck by driving, and the rotating part can be adjusted by turning to make the chuck slide on the fixing part . When it is necessary to process the eccentric structure of the part, there is no need to remove the part, just rotate and adjust the rotating part according to the size of the eccentricity, and drive the chuck to drive the part to move to the required position, and then the eccentric processing of the part can be carried out. At the same time, It can also facilitate multiple eccentric adjustments and eccentric processing, without the need to correct the position of the parts before each adjustment.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an adjustable clamp. Background technique [0002] A fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position for construction or inspection. In the field of machining, eccentric shaft parts, such as crankshafts, are often encountered. The traditional machining method is usually to pad the jaws of the chuck with a gasket with a certain thickness calculated from the eccentricity to meet the machining needs. At the same time, in order to ensure the accuracy of the eccentricity, the thickness of the gasket must be adjusted several times to find the position of the workpiece. Since the processing of eccentric parts requires secondary clamping, it is easy to increase the clamping error and prolong the clamping time, so that the final processing error of the part is large and the processing efficiency i...
