Abstract

The utility model relates to a bearing fit press-in device, which belongs to the field of mechanical processing equipment. The bearing fit press-in device is characterized by comprising a press-in head (1) connected with an air pressure device, and a base (2) corresponding to the press-in head (1), wherein a pressure sensor (3) and a displacement sensor (4) are arranged in the front end of the press-in head (1), the pressure sensor (3) and the displacement sensor (4) are connected with a pressure and displacement monitoring device (5), and a pressure signal and a corresponding displacement signal are transmitted to the pressure and displacement monitoring device (5). The bearing fit press-in device increases pressure and displacement detection, measures the actual pressure and displacement in the process of pressing in the bearing, carries out storing and alarming via the monitoring device, completely eliminates the situation of bearing damage or drop caused by too large or small pressure due to the instability of an air pressure source, and ensures the consistency of quality and production.

Description

A kind of bearing cooperates press-in device

Technical field

The utility model relates to a kind of press-in device, relates in particular to a kind of bearing and cooperates press-in device.

Background technology

In the process of component of machine, the operation that often has bearing to be pressed into.Carry out bearing when being pressed into operation, adopt the method that manually adds machine tool the earliest, but strength is often not enough, and the special equipment that is pressed into has been arranged afterwards, equipment generally adopts air pressure as pressure source.By setting the value of air pressure, realize the control of pressure.

But add man-hour at some parts that the bearing quality of fit is had relatively high expectations, as the accessory that uses on some automobiles, see shown in the accompanying drawing 1, it is that the precision that need depend on the bearing cooperation could have good completeness in use that several places are arranged in the fork assembly of gear shift, and since when being pressed into bearing the value as the air pressure of pressure source wayward stable, the power that bearing is pressed into has skew, the excessive part of bearing or cooperation that may cause of strength sustains damage, may cause bearing to be pressed into tightly and easily to get loose inadequately, cause whole part not use and strength is too small.Though air pressure has been done corresponding voltage stabilizing control, still can't guarantee the consistency problem in a large amount of production processes.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of bearing and cooperates press-in device, solves the restive and definite defective that therefore can't determine the conformity of production of precision bearing mating parts of pressure that existing apparatus is pressed into.

Technical scheme

A kind of bearing cooperates press-in device, it is characterized in that: comprise the indenter that connects pneumatic compression devices and the base of indenter correspondence, pressure sensor and displacement transducer are housed in the front end of described indenter, described pressure sensor is connected pressure and displacement monitoring equipment with displacement transducer, send pressure signal and corresponding displacement signal to pressure and displacement monitoring equipment.

Described pressure and displacement monitoring equipment comprise memory and display screen, show the corresponding curve of pressure and displacement.

Described pressure and displacement monitoring equipment comprise comparator and alarm, when the pressure that comparator comparative pressure sensor transmits is greater than or less than setting pressure, output signal to alarm equipment alarm.

Beneficial effect

Bearing of the present utility model cooperates press-in device to increase pressure and displacement detecting, in the process that bearing is pressed into, record actual pressure and displacement, and store and report to the police by watch-dog, may or too smallly cause bearing is impaired or come off situation because of the unstable build-up of pressure overvoltage of pneumatic supply thereby thoroughly eliminated, and can be beneficial to subsequent analysis after the storage of pressure displacement data.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.

A kind of bearing cooperates press-in device, comprise the indenter 1 that connects pneumatic compression devices and the base 2 of indenter 1 correspondence, pressure sensor 3 and displacement transducer 4 are housed in the front end of described indenter 1, described pressure sensor 3 is connected pressure and displacement monitoring equipment 5 with displacement transducer 4, send pressure signal and corresponding displacement signal to pressure and displacement monitoring equipment 5.

Described pressure and displacement monitoring equipment 5 comprise memory and display screen, show the corresponding curve of pressure and displacement.

Described pressure and displacement monitoring equipment 5 comprise comparator and alarm, when the pressure that comparator comparative pressure sensor transmits is greater than or less than setting pressure, output signal to alarm equipment alarm.

As shown in Figure 1 be unkitted the 1/2 grade of fork assembly for preparing, need be pressed into bearing processing in the position shown in the dotted line up and down, accompanying

drawing

3 and 4 is depicted as and carries out the schematic diagram that bearing 6 is pressed into respectively in both sides, in finishing the process that bearing is pressed into, pressure sensor 3 and displacement transducer 4 are sent to pressure and displacement monitoring equipment 5 with pressure and displacement signal, demonstrate the pressure displacement curve, should then in scope, all not send chimes of doom at 1000N to 5000N as the setting pressure scope.

Bearing of the present utility model cooperates press-in device to increase pressure and displacement detecting, in the process that bearing is pressed into, record actual pressure and displacement, and store and report to the police by watch-dog, may or too smallly cause bearing is impaired or come off situation because of the unstable build-up of pressure overvoltage of pneumatic supply thereby thoroughly eliminated, guarantee the uniformity of quality and production, and can will be beneficial to subsequent analysis after the storage of pressure displacement data.
