Description

A kind of guide rod type assembling device for snap spring

Technical field

The present invention relates to a kind of assembling device of axle jump ring, specially a kind of guide rod type assembling device for snap spring.

Background technology

Axle is a kind of part for being arranged on axial trough, being axially moved for limiting parts with jump ring, is led in mechano-electronic Domain is widely used.

In all kinds of jump ring applications of in the market, its assembly method is to be completed by hand with Circlip tongs or jump ring tool mostly.Hand Work installation is wasted time and energy, and expends substantial amounts of human cost, production efficiency, while it is difficult to ensure that the stability of product quality.Other Some assembly methods also all automaticity is relatively low, or cannot be guaranteed that jump ring opening is accurately positioned, influence assembly yield, Or automatic assembling process complexity is, it is necessary to which the cooperation of multiple motions, production efficiency are relatively low.

The content of the invention

It is an object of the invention to provide a kind of guide rod type assembling device for snap spring, is that a kind of structure is simpler, the motion of cooperation Number is less, and jump ring positions more accurately axle assembling device for snap spring, so as to improve efficiency of assembling and the degree of accuracy.

The purpose of the present invention can be realized by following technical scheme:

A kind of guide rod type assembling device for snap spring, including feed mechanism, delivery device and detent mechanism;The feed mechanism bag Storing bar and feeding blade are included, the section of the storing bar is that circle adds sector structure, 3/4ths circular diameters of side More smaller than jump ring internal diameter, the sector region of storing bar bottom has the platform of protrusion, and a piece of jump ring thickness of thickness ratio is bigger, described to send Expect that a piece of jump ring of thickness ratio of blade is thin, front end is V-arrangement opening;The delivery device includes push blade and adjustable push rod, The push blade front end is also V-arrangement opening, is fixed with adjustable push rod on the center line of lower end, adjustable push rod by screw and nut and Insert bottom connection is pushed, length can finely tune, and be hemispherical anti-abrasive material at the top of adjustable push rod;The detent mechanism includes Back-moving spring and guide rod, the guide rod are formed by three sections, and first paragraph is connected by back-moving spring with operating desk, second segment and the 3rd Section upper surface and ejector pin contact, the angle rotated by the contact control guide rod of diverse location, the 3rd section of upper surface of guide rod by Narrow to broaden, embedded jump ring inner ring ensures positioning precision more and more higher, and widest portion is less than the width of jump ring open front.

Using technical scheme, following effect can be obtained:

The present invention is coordinated by horizontal and vertical two motions completes assembling, and motion process is simple, and productivity ratio is higher;Pass through Guide rod is progressively positioned to jump ring, ensures positioning precision more and more higher.

Embodiment

The invention will be further described with example below in conjunction with the accompanying drawings.

With reference to Fig. 1 and Fig. 2, a kind of guide rod type assembling device for snap spring, including feed mechanism 1, delivery device 2, detent mechanism 3.The feed mechanism 1 includes storing bar 11 and feeding blade 12.The section of storing bar 11 is circular plus sector structure, side 3/4ths round diameters are more smaller than jump ring internal diameter, so as to ensure that jump ring can freely move up and down along storing bar 11.Storing bar 11 The sector region of bottom has the platform of protrusion, and a piece of jump ring thickness of thickness ratio is bigger, so that the cylinder for being cased with a string of jump rings hangs Sky, and then when storing bar 11 and fixed operating desk contact, lowermost a piece of jump ring drops out, and is prepared for feeding.It is described to send It is above V-arrangement opening to expect blade 12, can be contacted well with jump ring, a piece of jump ring of thickness ratio is thin, so as to storing bar 11 nethermost a piece of jump rings are released, without being collided with second from the bottom jump ring.

With reference to Fig. 1 and Fig. 3, Fig. 4, the delivery device 2 includes push blade 21 and adjustable push rod 22.Before pushing blade 21 End and V-arrangement opening, it is responsible for jump ring being pushed in assembled shaft.Adjustable push rod is fixed with the push lower end center line of blade 21 22, adjustable push rod 22 is connected by screw and nut with push blade 21 bottom, and length can finely tune, and the adjustable top of push rod 22 is half The upper surface of guide rod 32 in spherical anti-abrasive material, and detent mechanism 3.When pushing blade 21 and moving forward and backward, by can Adjust push rod 22 to press guide rod 32 to rotate.

The detent mechanism 3 includes back-moving spring 31 and guide rod 32.Guide rod 32 is formed by three sections, and first paragraph is by resetting bullet Spring 31 connects with operating desk, and second segment and the 3rd section of upper surface contact with adjustable push rod 22, is controlled by the contact of diverse location The angle that guide rod 32 rotates.3rd section of upper surface of guide rod 32 is broadened by narrow, and embedded jump ring inner ring ensures positioning precision increasingly Height, widest portion are less than the width of jump ring open front.Back-moving spring 31 can ensure that adjustable push rod 22 and the upper surface of guide rod 32 are tight Contiguity is touched.

The use process of apparatus of the present invention is as follows:

With reference to Fig. 1 to Fig. 6, when assembling process starts, the lengthwise movement of feeding blade 12, a piece of jump ring is delivered into pusher The front end of structure 2, push blade 21 laterally travel forward, and control guide rod 32 to rotate up by adjustable push rod 22, the insertion card of guide rod 32 In spring endoporus.Push blade 21 move forward, due to the change of contact surface, guide rod 32 is rotated down, the front end of guide rod 32 compared with Width, the guide rod 32 being embedded in jump ring broaden, so as to progressively adjust jump ring opening direction.When jump ring is close to assembled shaft, guide rod 32 Under rotation to operating desk, jump ring opening face assembled shaft, ensure the accuracy assembled.Assembling is completed, and push blade 21 is retracted, and is led Bar 32 first rotates up, and when the contact surface of adjustable push rod 22 and guide rod 32 changes, guide rod 32 starts to be rotated down, and is sent for jump ring Material is prepared, and prevents the collision of jump ring and guide rod 32.
