Fixture with functions of locating detection and clamping expansion

Abstract

The invention discloses a fixture with the functions of locating detection and clamping expansion. The fixture comprises an up-and-down telescopic mechanism comprising a sliding shaft vertically arranged, a first spring and a first limit bolt component, and a workpiece to be installed can be arranged at the bottom end of the sliding shaft in a sleeving mode; the sliding shaft is internally provided with the first spring, and the sliding shaft is provided with a vertical straight slot; and the first end of the first limit bolt component is connected with the bottom end of the first spring, and the second end of the first limit bolt component penetrates through the straight slot horizontally, and extends outside. According to the fixture, a needle bearing is located and clamped through a locating contact, and whether the needle bearing is located correctly or not is judged through a proximity switch secondarily; it is ensured that the needle bearing is not twisted in the pressing process through an anti-rotating guide mechanism, and it is ensured that an outer ring hole of the needle bearing is aligned to a workpiece hole; the needle bearing is installed at the pressing position of a press, and both hands are far away from the press; the extrusion risk is avoided; and the perpendicularity is high for ensuring that the press mounting of the bearing can be finished quickly, and the press mounting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of automatic assembly, and in particular relates to a clamp with position detection and capable of clamping and stretching. Background technique [0002] When high-speed rolling and heavy load are required, the needles of needle roller bearings need to be lubricated with oil to improve their life. This needle roller bearing needs to be specially customized and has holes on its outer rolling surface. Needle bearings need to be pressed into the workpiece with the hole aligned with the oil hole. The current assembly method is that the worker holds the needle roller bearing, visually checks the alignment of the outer rolling surface of the needle roller bearing with the hole of the workpiece, and presses it in with a manual pressing tool. This assembly method has the following disadvantages, namely: [0003] 1. It is difficult to ensure that the outer rolling surface of the needle roller bearing can be accurately aligne...

AI Technical Summary

Problems solved by technology

[0003] 1. It is difficult to ensure that the outer rolling surface of the needle roller bearing can be accurately aligned with the oil injection hole by manual hand-held pressing. If the deviation is too large, the oil injection cannot be lubricated;

[0004] 2. Pressing in manually cannot free your hands. If there is improper operation, there is a risk of squeezing your hands;

[0005] 3. Manual hand-held press-in, it is difficult to ensure that the bearing is pressed vertically into the fitting hole, resulting in difficulty in press-fitting, and in severe cases, the needle roller and cage will be damaged; and the press-in needs to be pressed in slowly, making the press-fitting efficiency low
