[0023] Example 1

[0024] Provided is an automatic alignment device for processing eccentric bolts, comprising a platform 20, a cover plate 30 and an alignment assembly 60.

[0025] The platform 20 is supported by the support frame 10. The platform 20 is provided with a socket 21 for placing the head of the eccentric bolt. The socket 21 is provided with an axial hole 22 which passes through the platform 20 vertically downward. The axial hole 22 is used to pass the eccentric bolt screw.

[0026] The cover plate 30 is connected to the platform 20 through a pin 31, and the pin 31 is rotatably inserted into the platform 20. The cover plate 30 can be pivoted to above the socket 21. A limiting portion 40 is installed on the cover plate 30 to prevent the eccentric bolt head from tilting, that is, the eccentric bolt head is placed in the socket 21 and remains horizontal.

[0027] The alignment component 60 includes a first arc plate 61 fixedly connected to the lower end of the axial hole 22 and a first telescopic source 62 installed at the bottom of the platform 20. The movable end of the first telescopic source 62 is connected to the second arc plate 63. The second arc plate 63 and the first arc plate 61 can be spliced ​​to form a clamping cavity. The clamping cavity clamps the eccentric bolt screw and is collinear with the center line of the eccentric bolt screw. The first telescopic source 62 is preferably a hydraulic cylinder, which can drive the second arc plate 63 to be close to the first arc plate 61 to form a clamping cavity. The clamping cavity clamps the eccentric bolt screw by pushing it to move. The eccentric bolt screw after clamping is collinear with the center line of the clamping cavity and can be processed after alignment is completed. The clamping cavity formed by the second arc plate 63 and the first arc plate 61 does not contact the eccentric part on the eccentric bolt screw, that is, the eccentric part is located below the formed clamping cavity.

[0028] Example 2

[0029] On the basis of Example 1, the lower end of the second arc plate 63 is connected to a fixed plate 65, and a guide rod 66 is arranged at the bottom of the platform 20. The guide rod 66 is passed through the fixed plate 65, so that the first telescopic source 62 drives the second arc plate 63 to move laterally along the guide rod 66, and has good stability; the inner walls of the second arc plate 63 and the first arc plate 61 are both provided with protrusions 64 that can contact the eccentric bolt screw. The protrusions 64 are provided to improve the clamping effect of the eccentric bolt screw, and it is not easy to shake during processing, which effectively ensures the processing accuracy.

[0030] In this embodiment, the limiting portion 40 includes a second telescopic source 41, and the movable end of the second telescopic source 41 is connected to a pressure plate 42, on which a plurality of upper balls 421 are arranged, and a plurality of lower balls 211 are arranged on the bottom wall of the socket 21. The second telescopic source 41 is preferably a micro-electric cylinder. When aligning the eccentric bolt, the cover plate 30 pivots to the top of the socket 21, and the pressure plate 42 is driven downward by the second telescopic source 41, so that the upper and lower sides of the eccentric bolt head are limited, and the eccentric bolt head will not be deflected. After the screw is pushed by the second arc plate 63, the eccentric bolt is moved laterally as a whole, and the friction force on the movement of the eccentric bolt head is reduced by the plurality of lower balls 211 and the plurality of lower balls 211.

[0031] In this embodiment, the pin 31 is wrapped with a torque spring 32, and a power source 50 is installed on the platform 20. The output shaft of the power source 50 is connected to a cam 51, and the cam 51 is in contact with the cover plate 30. The power source 50 is preferably a motor, which can drive the cam 51 to rotate, so as to push the cover plate 30 to move above the socket 21. There is no need to manually rotate the cover plate 30, thereby further improving the automation of eccentric bolt alignment. At the same time, the cover plate 30 is reset to leave the socket 21 by the torque spring 32, which facilitates the processing and placement of the eccentric bolt.

[0032] Working principle:

[0033] The eccentric bolt head is placed in the socket 21, the eccentric bolt screw is passed through the axial hole 22, and then the cover plate 30 is pivoted to above the socket 21. The eccentric bolt head is placed in the socket 21 and kept horizontal through the limiting part 40. The first telescopic source 62 is controlled to drive the second arc plate 63 to approach the first arc plate 61 to form a clamping cavity. The clamping cavity is clamped by pushing the eccentric bolt screw to move. The clamped eccentric bolt screw is aligned with the center line of the clamping cavity to complete the alignment. The aligned eccentric bolt can be processed, and the eccentric bolt can be automatically aligned and clamped. Only the eccentric bolt needs to be taken and placed. The operation is simple and convenient, which effectively improves the efficiency of alignment.
