Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings by way of examples.

The utility model provides a precision equipment leveling, measurement, inspection universal mechanism in narrow and small space, as shown in figure 1, including rotating member 1, screw rod 2, mounting 3 and jackscrew 4.

The screw 2 is provided with a scale 8 for the dimensional reference of the position of the rotary member 1. One end of the screw rod 2 is fixedly connected with the fixed part 3 and is used as a reference end, the other end of the screw rod 2 is in threaded connection with the rotating part 1, and the outer side end face of the rotating part 1 is always parallel to the outer side end face of the fixed part 3.

The height of the whole universal mechanism is adjusted by manually screwing the rotary piece 1 so as to meet the requirement of a preset size which is not more than 10 cm. The rotating piece 1 is locked and limited by the jackscrew 4 after rotating in place.

The rotary part 1 and the fixing part 3 are both provided with knurls 5, so that the operation is convenient. The rotating part 1 and the fixing part 3 are of boss structures, and knurling 5 is arranged on the outer circumference of the large-diameter part, so that manual operation is facilitated. When installed, the small diameter portion of the rotary member 1 and the small diameter portion of the stationary member 3 face inward.

When leveling and checking are carried out, more than one, preferably three can be adopted according to the actual installation situation.

According to the actual conditions, the screw rod 2 can replace the middle shaft with fixed size to meet various requirements, namely, the whole height of the universal mechanism is not required to be adjusted through the rotating part 1. For mass-produced plants, the spacing is constant, and this can be used.

When leveling and mounting:

step one, selecting the size of the screw rod 2 according to the installation height requirement of the parts to be installed.

And step two, finishing the assembly of the rotating part 1, the screw rod 2 and the fixing part 3.

And thirdly, screwing the rotating piece 1 according to the installation size requirement, adjusting the height size according to the size on the screw rod 2, and fixing the jackscrew 4.

And step four, after the universal mechanism is placed on one side of the installation part I6, assembling a part II 7 which needs to be kept horizontal with the part I6 by taking the upper end face of the universal mechanism rotating piece 1 as a reference.

Three general mechanisms may be employed in step four.

When in detection:

step one, selecting the size of the screw rod 2 according to the installation height requirement of the parts to be installed.

And step two, finishing the assembly of the rotating part 1, the screw rod 2 and the fixing part 3.

And thirdly, screwing the rotating piece 1 according to the installation size requirement, adjusting the height size according to the size on the screw rod 2, and fixing the jackscrew 4.

And step four, placing the universal mechanism between the component I6 and the component II 7, pushing the universal mechanism in all directions, and if the universal mechanism is blocked or has a gap, indicating that the two components are not parallel.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
