The aligning component 3 comprises a first vice seat 30 and a second vice seat 31 which are arranged adjacently, an upper vice jaw 32 which is in sliding fit on the first vice seat 30 and a lower vice jaw 33 which is in sliding fit on the second vice seat 31, ball head adjusting pins 34 are respectively arranged on the upper vice jaw 32 and the lower vice jaw 33, the ball head adjusting pins 34 of the upper vice jaw 32 are abutted with the outer conical surface of the upper half-ring part, the ball head adjusting pins 34 of the lower vice jaw 33 are abutted with the outer conical surface of the lower half-ring part, and the driving component 4 is respectively in power connection with the upper vice jaw 32 and the lower vice jaw 33 of the two groups of aligning components 3. The positioning assembly 2 comprises a positioning pin 20 and a positioning seat 21 which are arranged on the base 1, an adjusting rod 22 vertically arranged on the positioning seat 21, a pressing plate 23 rotatably arranged at the end part of the adjusting rod 22, and a locking cap 24 arranged at the end part of the adjusting rod 22 and used for locking the rotating position of the pressing plate 23, wherein the pressing plate 23 is in compression joint with the upper end of the upper half-ring part. The adjusting rod 22 is connected with the positioning seat 21 through threads, and the stability of support is improved through the self-locking performance of the threads. The locking cap 24 is a screw cap. When the automatic positioning device is used, the upper half ring part and the lower half ring part are positioned together through the upper positioning pin 20 of the clamp and the upper half ring positioning hole, so that the parts can only swing left and right, then the synchronous rotating screw rod is rotated to enable the lower jaw 32 and the upper jaw 32 to synchronously move until the ball head adjusting pin 34 is contacted with the outer conical surface of the parts, and the automatic positioning is completed.
The driving assembly 4 comprises an upper base body 40, a lower base body 41, a positioning roller 42 arranged on the upper base body 40, an upper synchronous rotating screw 43 penetrating through the positioning roller 42, and a lower synchronous rotating screw 44 arranged on the lower base body 41, wherein two ends of the upper synchronous rotating screw 43 are respectively in threaded connection with the upper jaws 32 of the two sets of alignment assemblies 3, and two ends of the lower synchronous rotating screw 44 are respectively in threaded connection with the lower jaws 33 of the two sets of alignment assemblies 3. In order to ensure the rigidity of the rotary screw and the concentricity of the left-handed thread 431 and the right-handed thread 432, the rotary screw can be equally divided into two equal parts and connected by adopting the annular positioning roller 42, so that the requirement on the concentricity of the threads is ensured, the manufacturing difficulty is reduced, a certain supporting effect is realized on the rotary screw, and the rigidity of the screw is increased.
As shown in fig. 3, each of the upper synchronous rotation screw 43 and the lower synchronous rotation screw 44 includes a rod 430, a left-handed thread 431 disposed at one end of the rod 430, and a right-handed thread 432 disposed at the other end of the rod 430, and the rod 430 is connected to the positioning roller 42 in a matching manner and is in rotational fit with the positioning roller 42. The left-handed thread 431 and the right-handed thread 432 are both T-shaped threads, so that in order to avoid the phenomenon of axial movement of the screw rod, a fixed groove in the positioning roller 42 is matched, and a unilateral gap of 0.005-0.01 is ensured, so that the axial movement of the rotating screw rod is eliminated, and the synchronous movement effect of the adjusting pin is improved. In order to avoid damage to the semi-ring parts, when the rotating screw rod is twisted, the distance between the adjusting pin and the conical surface of the part is adjusted by using a 0.02 feeler gauge on the outer conical surface of the part until the feeler gauge can be pulled out just enough to finish the positioning requirement.
