Described detection platform is also provided with a lift cylinder vertically arranged, the output terminal of described lift cylinder is connected with an elevator, described elevator is provided with the compact heap suitable with the inner ring of workpiece to be detected, and described compact heap is positioned at the top of described work piece platform;
Described elevator is also provided with a rear push cylinder horizontal along the longitudinal direction, the output terminal of described rear push cylinder is connected with pushing block after;
The detection platform at described work piece platform rear is also provided with a front push cylinder horizontal along the longitudinal direction, pushing block before the output terminal connection one of described front push cylinder, described front pushing block is provided with displacement transducer; The front end of this front pushing block is provided with the sliding front-slider established into this front pushing block, and this front-slider is corresponding with described displacement transducer.
Further, the frame in described work piece platform front is provided with the slide rail of fore-and-aft direction, and described slide rail is slidably equipped with slide unit, described frame is also provided with passing cylinder horizontal along the longitudinal direction, and the output terminal of this passing cylinder is connected with described slide unit;
Described slide unit is provided with gripping cylinder horizontal in left-right direction, and described gripping cylinder is connected with the mechanical arm for gripping workpiece.
Further, be also connected by spring between described front-slider and described front pushing block.
The utility model also has following additional technical feature:
Described front-slider is also provided with front top arm.
Described detection platform is provided with a lifting support, and described lift cylinder is located on described lifting support; Push away support before described detection platform is also provided with, described front push cylinder be located at described before push away on support.
Workpiece to be detected (i.e. the combination of the retainer of taper roll bearing, roller, inner ring) in use, is placed in work piece platform by the utility model, and then lift cylinder drives elevator and compact heap to decline, and the band inner ring that detects workpiece compresses by compact heap; Then front pushing block pushes away forward by front push cylinder, that is drives front-slider to push away forward, until front-slider is touched mutually with the retainer that band detects workpiece, now the distance between the rear end face of front-slider and displacement transducer recorded by displacement transducer; Push cylinder action afterwards, after driving, pushing block pushes away backward, rear pushing block promotes retainer and moves backward, retainer is by front-slider to pusher, and the distance between the rear end face of front-slider and displacement transducer recorded again by displacement transducer, by the difference of the rear end face of front-slider and the spacing of displacement transducer under calculating two states, the play of retainer can be learnt, if play is excessive, then shows that the riveting of retainer is fixed defective or it is fixed not carry out riveting at all, thus judge defective.
The beneficial effects of the utility model are: provide a kind of taper roll bearing retainer pick-up unit, can detect, substantially increase detection efficiency, reduce loss and false drop rate whether the installation of taper roll bearing retainer is qualified.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of taper roll bearing retainer pick-up unit, comprises frame 1, and described frame 1 has a detection platform 2, and described detection platform 2 is provided with the work piece platform 4 for placing workpiece 3 to be detected.
Described detection platform is also provided with a lift cylinder 5 vertically arranged, the detection platform described in the present embodiment is provided with a lifting support 6, and described lift cylinder 5 is located on described lifting support 6, simple installation.The output terminal of described lift cylinder 5 is connected with an elevator 7, and described elevator 7 is provided with the compact heap 8 suitable with the inner ring of workpiece to be detected, and described compact heap 8 is positioned at the top of described work piece platform 4.
Described elevator 7 is also provided with a rear push cylinder 9 horizontal along the longitudinal direction, the output terminal of described rear push cylinder 9 is connected with pushing block 10 after.
The detection platform at described work piece platform 4 rear is also provided with a front push cylinder 11 horizontal along the longitudinal direction, in the present embodiment, before described detection platform is also provided with, pushes away support 12, described front push cylinder 11 be located at described before push away on support 12, simple installation.Pushing block 13 before the output terminal connection one of described front push cylinder, described front pushing block 13 is provided with displacement transducer 14; The front end of this front pushing block 13 is provided with the sliding front-slider 15 established into this front pushing block, and this front-slider 15 is corresponding with described displacement transducer 14.
In use, the combination by the retainer of workpiece 3(to be detected and taper roll bearing, roller, inner ring) be placed in work piece platform 4, then lift cylinder 5 drives elevator 7 and compact heap 8 to decline, and the band inner ring that detects workpiece compresses by compact heap 8; Then front pushing block 13 pushes away forward by front push cylinder 11, that is drive front-slider 15 to push away forward, until front-slider 15 is touched mutually with the retainer that band detects workpiece, in the present embodiment, described front-slider 15 is also provided with front top arm 16, touch mutually with the retainer of workpiece to be detected by front top arm 16, touching area is less, reacts sensitiveer.Now the distance between the rear end face of front-slider 15 and displacement transducer 14 recorded by displacement transducer 14; Push cylinder 9 action afterwards, after driving, pushing block 10 is to pusher, rear pushing block 10 promotes retainer and moves backward, retainer by front-slider 15 to pusher, the distance between the rear end face of front-slider 15 and displacement transducer 14 recorded again by displacement transducer 14, by the difference of the rear end face of front-slider 15 and the spacing of displacement transducer 14 under calculating two states, the play of retainer can be learnt, if play is excessive, then show that the riveting of retainer is fixed defective or it is fixed not carry out riveting at all, thus judge defective.Read the numerical value of displacement transducer and the process of carrying out data calculating can be established outside on computer equipment and carried out, these realize by existing ripe software engineering.
Also be connected by spring 17 between front-slider 15 described in the present embodiment and described front pushing block 13, after front push cylinder 11 resets, front-slider 15 can automatically reset by spring.
In the present embodiment, the frame in described work piece platform front is provided with the slide rail 18 of fore-and-aft direction, described slide rail 18 is slidably equipped with slide unit 19, described frame is also provided with passing cylinder 20 horizontal along the longitudinal direction, the output terminal of this passing cylinder 20 is connected with described slide unit 19; Described slide unit is provided with gripping cylinder 21 horizontal in left-right direction, and described gripping cylinder 21 is connected with the mechanical arm 22 for gripping workpiece.The meaning of design said mechanism is, by mechanical arm 22 gripping workpiece to be detected, by gripping cylinder 21, workpiece to be detected is moved to the dead ahead of compact heap 8, then by passing cylinder 20, workpiece to be detected is moved to immediately below compact heap 8, thus realize self-feeding.
