Description

Small length-diameter ratio roller vibration feeding mechanism

Technical Field

The utility model belongs to little draw ratio roller processing technology especially relates to a little draw ratio roller vibration feed mechanism.

Background

The small and medium-sized cylindrical rollers are generally fed by a vibration hopper when the outer diameter and the end surface of the roller are ground, and the roller enters a machine tool for grinding in a way of connecting the head and the tail of the roller by utilizing a component force generated by vibration, so that the small and medium-sized cylindrical rollers have the advantage of high feeding efficiency. However, when a cylindrical roller with the length-diameter ratio less than or equal to 1.2 is machined, most of the roller is erected on a guide trough of a vibrating disc due to small difference between the diameter and the length, and cannot smoothly enter a machine tool for grinding, so that the feeding efficiency is low. In order to ensure the feeding progress, only a specially-assigned person needs to be responsible for removing the standing workpiece, so that the processing cost is obviously increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a little draw ratio roller vibration feed mechanism to there is the problem of material loading inefficiency in the time of solving among the prior art little draw ratio roller vibration material loading.

To achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a little draw ratio roller vibration feed mechanism, its includes the vibration hopper main part, the top of vibration hopper main part is provided with the vibration hopper dish, the inner wall of vibration hopper dish is provided with the guide silo, wherein, the guide silo is convex and its radian matches with the radius of waiting to process the roller, the outside terminal surface of guide silo with contained angle theta has between the horizontal center line of guide silo.

Further, the included angle θ is 13 ° to 17 °.

Preferably, the angle θ is any one of 13 °, 14 °, 15 °, 16 °, or 17 °.

Furthermore, a spring pipe located on the outer side of the vibrating hopper disc is arranged at the discharge port of the guide trough, and the arranged rollers to be processed are input into the grinding machine tool through the spring pipe.

Furthermore, a material baffle is vertically arranged at the position, close to the discharge port of the guide trough, of the inner side of the vibrating hopper disc, and the rollers to be machined, which are individually erected, are removed through the material baffle.

The beneficial effects of the utility model are that, compare with prior art the radian of little draw ratio roller vibration feed mechanism's guide silo is close with the radius of waiting to process the roller, and under the combined action of theta angle in addition for erect automatic sliding in vibration hopper dish bottom on the guide silo, vibrate again upwards, the roller of crouching in the guide silo then continues to advance and send to the lathe grinding region. Not only the structure is simple, but also the design is ingenious; but also ensures the feeding efficiency and reduces the processing cost to a certain extent.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a single embodiment. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, in the present embodiment, a small-aspect-ratio roller vibration feeding mechanism is suitable for automatically feeding cylindrical rollers with an aspect ratio of less than or equal to 1.2, and includes a vibration hopper main body 1, a vibration hopper disc 2 is disposed at the top of the vibration hopper main body 1, a guide trough 3 is disposed on an inner wall of the vibration hopper disc 2, a spring tube 4 located at an outer side of the vibration hopper disc 2 is disposed at a discharge port of the guide trough 3, and a discharged roller 5 to be processed is input into a grinding machine tool through the spring tube 4.

The guide trough 3 is arc-shaped, the radian R of the guide trough 3 is matched with the radius of the roller 5 to be machined, an included angle theta is formed between the end face of the outer side of the guide trough 3 and the horizontal central line of the guide trough 3, and theta =15 degrees, so that the roller 5 to be machined, which is erected on the guide trough 3, automatically slides into the bottom of the vibrating hopper disc 2 in the vibrating feeding process under the combined action of the angle theta and the radius of the roller 5 to be machined, vibrates upwards again, and the roller 5 to be machined, which is laid in the guide trough 3, continues to move forwards and enters the spring tube 4 to the grinding area of the machine tool.

In order to ensure that the extremely individual vertical rollers to be processed 5 can be eliminated, a baffle plate 6 is vertically arranged at the position, close to the discharge port of the guide trough 3, of the inner side of the vibrating hopper disc 2, and the extremely individual vertical rollers to be processed 5 conveyed to the discharge port of the guide trough 3 are blocked and fall to the bottom of the vibrating hopper disc 2 through the baffle plate 6.

Above-mentioned small draw ratio roller vibration feed mechanism can reject the roller 5 of treating of standing on guide silo 3 automatically to make the inslot treat that processing roller 5 homoenergetic end to end, uninterrupted, smoothly get into the grinding region in succession, reduce the pay-off personnel of special nurse, reduce cost guarantees the dimensional stability after the product processing simultaneously.
