Abstract

The utility model discloses a flexibility detection device of a needle bearing. The flexibility detection device comprises a base seat, wherein a roll shaft is rotatably disposed on the base seat and used for fixing bearing retainers, a fixing seat is slidably disposed at one side of the roll shaft, and a motor is disposed in the fixing seat, and the roll shaft is provided with a fixing hole matched with the output shaft of the motor; the fixing seat is connected with a driving device used for driving the fixing seat to slide, and a position of the base seat where the roll shaft is positioned is provided with a clamping block set used for serving as an outer ring of the bearing retainers; and the flexibility detection device also comprises a sensor used for detecting rotation turns of the roll shaft. The flexibility detection device has the advantages that flexibility of the needle bearing can be detected automatically, and detection efficiency is high and detection effect is accurate.

Description

A kind of pick-up unit of needle bearing dirigibility

Technical field

The utility model relates to a kind of checkout equipment of needle bearing, more specifically, relates to a kind of pick-up unit of needle bearing dirigibility.

Background technology

Needle bearing is the roller bearing with cylindrical roller, and its diameter relatively, roller are not only carefully but also long.This roller is called needle roller.Although have less cross section, bearing still has higher load-bearing ability, therefore, is specially adapted to the restricted occasion of radial space.

Need all generally that dirigibility detects to bearing, conventional method is that bearing is installed on roll shaft, manually stir bearing, because the inertia roll shaft can stop after rotating a fixing turn, the number of turns of according to roll shaft, rotating judges whether bearing meets standard, this mode detection efficiency is low, and detection is not accurate, therefore is necessary to make improvements.

Summary of the invention

For the deficiencies in the prior art, the utility model provides a kind of pick-up unit of needle bearing dirigibility, can automatically detect the bearing dirigibility and whether meet standard.

the utility model is achieved by the following technical solution: a kind of pick-up unit of needle bearing dirigibility, comprise base, rotate the roll shaft that is provided for the solid bearing retainer on described base, a Slideslip at described roll shaft arranges holder, in described holder, motor is set, offer the fixed orifice with described motor output shaft coupling on described roll shaft, described holder connects with the drive unit that is connected the holder slip, the position that described base is positioned at described roll shaft is provided be used to the clamp group of serving as the retainer outer ring, also comprise the sensor that rotates the number of turns for detection of roll shaft.

In technique scheme, the drive unit that drives described holder slip is cylinder.

The utlity model has following beneficial effect: can realize the automatic detection of needle bearing dirigibility, detection efficiency is higher and the detection effect is more accurate.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 4, a kind of pick-up unit of needle bearing dirigibility, comprise base 1, described base 1 has the first plate body 10 and the second plate body 11 that vertically is oppositely arranged, and at the first plate body 10 and the second plate body 11 lower horizontal, is fixedly installed the 3rd plate body 12.Be horizontally disposed with guide pole 13 between described the first plate body 10 and the second plate body 11.

be positioned on the second plate body 11 and rotate the roll shaft 2 that is provided for the solid bearing retainer at described base 1, a side at described roll shaft 2 arranges holder 3, described holder 3 slides and is arranged on described guide pole 13, be fixedly installed motor 30 in described holder 3, offer the fixed orifice (accompanying drawing does not mark) with described motor output shaft coupling on described roll shaft 2, described holder 3 connects with the drive unit that is connected holder 3 slips, preferred described drive unit is cylinder 5, described cylinder is fixed on described holder 3, the to-and-fro movement of the cylinder rod by described cylinder, the output shaft that promotes described motor 30 enters or leaves described fixed orifice.

The position that described base 1 is positioned at described roll shaft 2 is provided be used to the clamp group 4 of serving as the retainer outer ring, described clamp group 4 comprises and is arranged at the described clamp 40 that is arranged on roll shaft 2 both sides, has the semicircle opening 400 that coordinates with the retainer size in clamp 40, when described motor 30 output shafts entered described fixed orifice, the clamp 40 of both sides was drawn close and is clamped retainer (i.e. the outer ring that bearing is served as in the mutual amalgamation of semicircle opening 400 of clamp 40 at this moment) to roll shaft 2.

Also comprise the sensor (accompanying drawing does not mark) that rotates the number of turns for detection of roll shaft 2.

During use, mechanical arm by automatic feeding is sent into retainer on roll shaft 2, cylinder 5 promotes holders 3 at this moment, make the output shaft of the motor 30 in holder 3 enter in the fixed orifice of roll shaft 2 one sides, clamp 40 is drawn close the clamping retainer to roll shaft 2 simultaneously, at this moment after the electric machine rotation certain hour, cylinder pushing motor output shaft leaves fixed orifice, rotate the sensor effect of the number of turns this moment for detection of roll shaft, detection due to inertia effect after the number of turns that is rotated further of roll shaft, the number of turns of according to roll shaft, rotating judges whether the bearing flexibility ratio meets the requirements.

Claims
