As an optimal technical solution, the motor is fixed on the slider of the cylinder platform through a spring and an adjusting screw, and the adjusting screw adjusts the elastic force of the spring, and at the same time adjusts the friction between the rubber wheel and the eccentric shaft part through the adjusting screw.

As a preferred technical solution, a safety grating is also included, and the safety grating is installed on opposite surfaces of the vertical plate, which are arranged symmetrically.

As a preferred technical solution, the eccentric shaft part is placed on the detection jig of the CCD measuring instrument, and the detection jig is controlled by a foot switch.

Detailed ways

All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and/or steps.

Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "central", "end The orientation or positional relationship indicated by "part", "length", "outer end", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying No device or element must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the invention.

In addition, in the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

Terms such as "upper", "above", "under", "below" used in the present invention to indicate relative positions in space are for the purpose of description to describe a unit or feature as shown in the drawings relative to A relationship to another cell or feature. The terms of spatial relative position may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or in other orientations) and spatially relative descriptors used herein interpreted accordingly

In this utility model, unless otherwise clearly specified and limited, terms such as "setting", "socketing", "connecting", "through", and "inserting" should be understood in a broad sense, for example, it can be a fixed connection , can also be detachable connection, or integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediary, can be the internal communication of two components or the mutual connection of two components Functional relationship, unless expressly defined otherwise. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present utility model according to specific situations.

As shown in Figure 1, it includes a table 1, a vertical plate 2, a cylinder 3, a slider 4, a motor 5, a CCD measuring instrument 6, an electric control box 7, a display 8, a safety grating 9, and a foot switch 10.

After starting up, the operator puts the eccentric shaft parts on the detection fixture 6-1 of the CCD measuring instrument 6, and after the manual withdrawal, step on the foot switch 10, the machine can run automatically: the motor 5 drives the rubber wheel 5-1 at a constant speed Rotate, the cylinder 3 drives the motor 5 to move downward, and the rubber wheel 5-1 on the motor 5 shaft is pressed on the eccentric shaft parts, and the eccentric shaft parts are driven to rotate at a uniform speed for more than one circle by friction. The CCD measuring instrument 6 takes pictures and measures in real time, and can measure the eccentricity, diameter, length and other dimensions. Display 8 can show the numerical value of measured size and the prompt of qualified or unqualified. After the measurement is completed, the motor 5 stops rotating, and the cylinder 3 drives the motor 5 to move upward. The operator removes the measured eccentric shaft parts from the testing jig 6-1, and then puts the eccentric shaft parts to be tested. After the operator withdraws, he depresses the foot switch 10, and then the next cycle operation.

The motor 5 is fixed on the slide block 4 of the cylinder platform, and is connected with the adjustment screw 4-2 by the spring 4-1. When the cylinder 3 drives the motor 5 and the rubber wheel 5-1 on the motor 5 shaft is pressed on the eccentric shaft part, the spring 4-1 can be compressed and buffered to avoid impacting the eccentric shaft part. The adjusting screw can adjust the elastic force of the spring 4-1, thereby adjusting the frictional force between the rubber wheel 5-1 and the eccentric shaft parts, ensuring that the eccentric shaft parts rotate smoothly, and the safety grating 9 can prevent the hands from entering and pinching.

The beneficial effects of the utility model are: the utility model effectively improves efficiency, reduces labor intensity, and reduces labor; the operation is simple, and the operator does not need special skills.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
