[0002] A workpiece with the axes of its outer circles parallel but not coincident is called an eccentric shaft. The eccentric shaft is generally fixed on the motor rotating shaft through an eccentric hole and performs a cam motion when the motor starts. Therefore, it is widely used in automobiles, engines, pumps, etc. The eccentric turntable is similar to the eccentric shaft, that is, a turntable is eccentrically installed on the rotating shaft.

[0003] When the existing device conducts experiments through the eccentric turntable, a fixture needs to be installed on the eccentric turntable. However, during the clamping and adjustment process of the fixture, if the adjusting part is damaged, it will cause inability to clamp, directly affecting the experimental progress; currently, during experiments, it is not convenient to quickly adjust the eccentricity of the eccentric turntable. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an eccentric turntable to solve the problems that when the existing device conducts experiments through the eccentric turntable, a fixture needs to be installed on the eccentric turntable. However, during the clamping and adjustment process of the fixture, if the adjusting part is damaged, it will cause inability to clamp, directly affecting the experimental progress; currently, during experiments, it is not convenient to quickly adjust the eccentricity of the eccentric turntable.

[0005] The purpose and efficacy of an eccentric turntable of the utility model are achieved by the following specific technical means:

[0006] An eccentric turntable includes a base; a test component is installed on the base.

[0007] Further, the test component is composed of a mounting rod, a connecting seat, a first connecting block, a seat body, a locking screw, and an auxiliary groove. A mounting rod rotates on the top end surface of the base, and a connecting seat is welded to one end above the mounting rod. Two first connecting blocks with a T-shaped block structure slide on the connecting seat, and the top end surfaces of the two first connecting blocks are welded to the bottom end surface of the seat body, and the bottom end surface of the seat body contacts the bottom end surface of the connecting seat.

[0008] Further, a locking screw is threadedly connected to the connecting seat, and the upper end of the locking screw passes through the connecting seat.

[0009] Further, an auxiliary groove is opened on the bottom end surface of the seat body. The auxiliary groove is a rectangular groove structure and is aligned with the locking screw.

[0010] Further, a clamping assembly is installed on the seat body. The clamping assembly is composed of a second connecting block, a guide rod, a threaded rod, a clamping block and an electric cylinder. Two second connecting blocks are welded to the top end surface of the seat body. Two guide rods are slidably arranged on each second connecting block. The right ends of the two guide rods on the left are welded to a clamping block respectively, and the right ends of the two guide rods on the right are welded to another clamping block respectively.

[0011] Further, a threaded rod is threadedly connected to each of the two second connecting blocks. One end of each of the two threaded rods is rotatably provided with an electric cylinder, and the extending ends of the two electric cylinders are respectively fixed on the two clamping blocks.

[0012] Further, a switch is fixed to the top end surface of the base. The switch is electrically connected to an external power supply and is also electrically connected to the two electric cylinders.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In this application, through the arrangement of the clamping assembly, on the one hand, when the two electric cylinders are controlled to extend, the two clamping blocks move inwards when the two electric cylinders extend, and the clamping of parts can be completed by the two clamping blocks. On the other hand, when the electric cylinder is damaged, rotate the threaded rod, and under the thread drive of the threaded rod, the movement of the clamping block can be realized. Compared with the existing device, this device can not only realize electric clamping, but also realize manual clamping when the electric cylinder is damaged and electric clamping cannot be realized, and has high practicability.

[0015] In this application, through the arrangement of the test assembly, on the one hand, when adjusting the eccentric angle of the seat body, loosen the locking screw, adjust the position of the seat body left and right by hand, and then tighten the locking screw after adjustment. On the other hand, after the locking screw is tightened, the top end of the locking screw abuts against the top end surface of the inner wall of the auxiliary groove. Even if the top end surface of the auxiliary groove is worn, it does not affect the normal sliding of the seat body. Compared with the existing device, this device can quickly realize the adjustment of the eccentric angle and has high adjustability. BRIEF DESCRIPTION OF THE DRAWINGS
