Problems solved by technology

[0003] In the prior art, during the conveying process of the workpiece on the pallet, the positioning accuracy between the pallet and the conveying equipment is not high, and since the workpiece is specifically a conical shell workpiece, it is difficult to accurately locate the workpiece on the positioning tool of the pallet. There will be a certain positioning deviation between
When press-fitting in this state, there will be misalignment between the pressure head of the press-fitting equipment and the pin shaft hole of the workpiece, resulting in difficulty in press-fitting. The workpiece is deformed and damaged, which is not conducive to the rapid assembly of the automated production line

Embodiment Construction

[0035] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0036] This embodiment provides a positioning device, which is mainly aimed at the positioning difficulty of some conical shell workpieces 500 when pressing parts such as the positioning pin shaft 501. Parts such as the positioning pin 501 to be pressed are smoothly and accurately pressed into the pin hole of the workpiece 500 .

[0037] This embodiment provides a positioning device, such as Figure 1-2 As shown, the positioning device includes: a positioning base assembly 1, a positioning mechanism 2, and a tapered roller bearing assembly 3. The upper end of the positioning mechanism 2 can be coaxially passed through the workpiece 500 and set opposite to the pin hole of the workpiece 500, and the positioning The lower end of the mechanism 2 runs through the positioning base assembly 1 coaxially, a...

Abstract

The invention belongs to the technical field of press-fitting, and discloses a positioning device. The positioning device comprises a positioning base assembly, a positioning mechanism and a conical roller bearing assembly; the upper end of the positioning mechanism can be coaxially arranged on a workpiece in a penetrating manner and is right opposite to a pin shaft hole of the workpiece to be arranged; the lower end of the positioning mechanism coaxially penetrates through the positioning base assembly, and meanwhile, the conical roller bearing assembly is coaxially arranged on the positioning mechanism in a sleeving manner and arranged between the positioning mechanism and the positioning base assembly; and the positioning mechanism is rotationally connected with the positioning base assembly through the conical roller bearing assembly. According to the positioning device, the positioning mechanism can perform automatic alignment for centering, so that the workpiece and a pressing head of a press-fitting device can be in accurate alignment, the deviation of upper and lower alignment can be reduced, and therefore damage caused by the fact that the workpiece deforms in the press-fitting process is reduced.

Description

technical field [0001] The invention relates to the technical field of press-fitting, in particular to a positioning device. Background technique [0002] For some conical shell workpieces, in the actual assembly process, the workpiece is usually conveyed to the position directly facing the pressure head of the press-fitting equipment through the pallet, and then the positioning pin shaft and other parts are pressed into the workpiece through the pressure head. middle. [0003] In the prior art, during the conveying process of the workpiece on the pallet, the positioning accuracy between the pallet and the conveying equipment is not high, and since the workpiece is specifically a conical shell workpiece, it is difficult to accurately locate the workpiece on the positioning tool of the pallet. There will be a certain positioning deviation between them. When press-fitting in this state, there will be misalignment between the pressure head of the press-fitting equipment and t...
