Embodiment 1

[0035] refer to figure 2 and image 3 , the cardan includes a cam mechanism 201, a first bracket 203, a second bracket 204 and a cam adjustment mechanism. Both the first bracket 203 and the second bracket 204 are "L" shaped, and the first bracket 203 is inserted into the second bracket 204 horizontally. The cam mechanism 201 is installed in the groove 2035 on the upper part of the first bracket 203 through the connecting bolt 202 . The cam mechanism 201 includes a cam 2011 and a handle 2012 . A cam adjustment mechanism is arranged in the groove 2035 to adjust the opening of the cam. The cam adjustment mechanism in this embodiment adopts an adjustment screw 211, and the adjustment screw 211 is installed at the bottom of the groove 2035. When the opening of the cam needs to be adjusted , just adjust the screw-in depth of the screw 211.

[0036] refer to figure 1 , the first bracket 203 includes a first bracket body and a cam mounting plate 2033 . The first bracket main bo...

Embodiment 2

[0042] refer to Figure 7 and Figure 8, Embodiment 2 is similar in structure to Embodiment 1, the only difference is that the cam adjustment mechanism in Embodiment 2 uses an adjustment block 212, and the adjustment block 212 is fixed on the inner wall of the groove 2035 by screws.

Abstract

The invention relates to a clamp, in particular to an adjustable eccentric clamp. The technical problems that existing clamps are poor in universality, low in efficiency and are prone to damaging workpiece surfaces are solved. According to the technical scheme, the adjustable eccentric wheel clamp includes a cam mechanism, a first supporting frame, a second supporting frame and a cam regulating mechanism; the first supporting frame and the second supporting frame are both L-shaped; the first supporting frame is transversely inserted into the second supporting frame; the cam mechanism is installed in a groove of the upper part of the first supporting frame; the cam regulating mechanism is arranged in the groove; a first kidney-shaped hole is formed in the first supporting frame; a fourth kidney-shaped hole is formed in the second supporting frame; a first bolt penetrates through the first kidney-shaped hole and the fourth kidney-shaped hole in sequence and is connected with a first nut;and the first supporting frame and the second supporting frame are connected slidably.

Description

technical field [0001] The invention relates to a collar, in particular to an adjustable eccentric wheel collar. Background technique [0002] In mechanical processing, Kalan is an important fixture, which is used to clamp the workpiece to complete the milling, drilling, tapping and other processes of the workpiece. refer to figure 1 , the existing Kalan includes a main body 101, a compression screw 102 and a reinforcing rod 103. The main body 101 is generally a monolithic structure, and the compression screw 102 compresses the workpiece through the threads on the main body 101. This structure has the problems of poor versatility, low efficiency and easy damage to the surface of the workpiece. Contents of the invention [0003] In order to solve the technical problems of poor versatility, low efficiency and easy damage to the surface of the workpiece in the prior art collar, the present invention provides an adjustable eccentric wheel collar. [0004] Technical solution...
