Description

Ball socket type end face leveling device

technical field

The invention belongs to the technical field of parallelism adjustment, in particular to a ball-and-socket type end surface leveling device.

Background technique

In many test bench equipment, there are often multiple planes or components whose relative positions need to be limited. In order to ensure the installation accuracy of the test bench equipment, the requirements for parallelism will be very high. For example, when installing a solid rocket motor push force test bench , it is necessary to increase the parallelism between the end face of the moving frame and the end face of the thrust pier in order to ensure accurate test results. In the installation and adjustment process of these high-precision test bench equipment, the traditional gasket adjustment method is difficult to meet the design requirements.

Contents of the invention

The object of the present invention is to provide a ball-and-socket type end face leveling device with simple structure, convenient adjustment and high adjustment accuracy.

The technical solution that realizes the object of the present invention is:

A ball-and-socket type end face leveling device, comprising an adjusting rod with a ball head at one end and an external thread at the other end, a base threaded with the adjusting rod, a ball socket matched with the ball end of the adjusting rod, and one end threaded with the ball socket , the other end is a connecting nut that is positioned in the vertical direction by the annular boss in the circumferential direction of the adjusting rod.

Compared with the prior art, the present invention has significant advantages:

The invention has a simple structure and is easy to assemble. During the process of height adjustment by rotation, due to the cooperation of the ball socket and the ball head, the upper and lower end faces remain stationary, which ensures the stability of the adjustment and has high adjustment accuracy.

The present invention will be described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of the overall structure of the ball-and-socket type end surface leveling device of the present invention.

Detailed ways

Combined with Figure 1:

The present invention is a ball-and-socket type end face leveling device, comprising an adjusting rod 2 with a ball head at one end and an external thread at the other end, a base 1 threaded with the adjusting rod 2, and a ball socket 4 matched with the ball end of the adjusting rod 2 , one end is threadedly matched with the ball socket 4, and the other end is a connecting nut 3 that is limited in the vertical direction by an annular boss in the circumferential direction of the adjusting rod 2.

Two symmetrical planes are arranged between the ball end and the threaded end of the adjusting rod 2 .

The base 1 is composed of a flat plate and a cylinder on the flat plate. The cylindrical barrel has an internally threaded hole, and the central axis of the internally threaded hole is perpendicular to the flat plate.

The connecting nut 3 is a cylindrical structure, one end has an internal thread, and the other end has an inwardly extending annular step surface, the internal thread cooperates with the thread on the outside of the bottom of the ball socket 4, and the annular boss in the circumferential direction of the adjusting rod 2 is on the connecting screw. The inside of the cap 3 is in contact with the inwardly extending annular step surface of the connecting nut 3 .

Example:

A ball-and-socket type end surface leveling device, comprising an adjusting rod 2 with a ball head at one end and an external thread at the other end, a base 1 threaded with the adjusting rod 2, a ball socket 4 matched with the ball end of the adjusting rod 2, and one end Cooperate with the ball socket 4 threads, the other end is the connecting nut 3 that is upper-limited in the vertical direction by the annular boss in the circumferential direction of the adjusting rod 2; two symmetrical planes are arranged between the ball end and the threaded end of the adjusting rod 2, and the base 1. It consists of a flat plate and a cylindrical tube on the flat plate. The cylindrical tube has an internally threaded hole. The central axis of the internally threaded hole is perpendicular to the flat plate. The connecting nut 3 is a cylindrical structure with internal threads at one end and an inwardly extending On the annular step surface, the internal thread cooperates with the thread on the outside of the bottom of the ball socket 4, and the circumferential annular boss of the adjusting rod 2 is in the connection nut 3 and contacts with the inwardly extending annular step surface of the connection nut 3.

The two planes arranged symmetrically between the ball end and the threaded end of the adjustment rod 2 can facilitate the use of a wrench to rotate the adjustment rod, and the rotation of the adjustment rod can adjust the distance that the adjustment rod protrudes from the base, thereby controlling the distance between the end surface of the ball socket and the bottom surface of the base.

The cooperation between the ball head and the ball socket 4 can make the ball head rotate in the ball socket 4, and the annular step surface on the connecting nut 3 contacts and cooperates with the ring-shaped boss on the connecting rod 2, so that the ball socket 4 and the adjusting rod 2 can be put on the ball. The heads are in close contact and ensure that their central axes coincide, so that the end face of the ball socket 4 is parallel to the ground of the base, and on the other hand, the ball socket 4 can also be prevented from sliding down.
