Description

Device for preventing workpiece from being damaged by squeezing

Technical Field

The application relates to the field of roller processing equipment, in particular to a device for preventing a workpiece from being damaged by extrusion.

Background

The roller belongs to a rolling body, the roller and the steel ball are the most important components of the bearing and are the most used rolling bodies in the bearing industry, and the quality of the roller directly influences the quality and the service life of the bearing. The basic processing process of the roller comprises rough grinding. The roller is used for polishing and roughly processing the outer peripheral wall and the double end faces of the roller through a grinding device such as a centerless grinding machine or a roller double-end-face grinding machine, and in the process, the roller firstly enters a material arranging mechanism through a feeding device and then is sent into the grinding machine through the material arranging mechanism.

Referring to fig. 7, the feeding device comprises a hopper 1 for placing rollers and a conveying channel for conveying the rollers, wherein the conveying channel is communicated with a material arranging mechanism.

The material arranging mechanism comprises two rotating rollers 2 arranged in parallel, a material arranging wheel 4 positioned above the rotating rollers 2 and a supporting plate 31 for mounting the rotating rollers 2, two baffle plates 3 are further arranged above the rotating rollers 2, and the two baffle plates 3 are clamped on two sides of the conveying channel and used for limiting the rollers to move along the extending direction of the rotating rollers 2. The baffle 3 is positioned at the previous station of the material arranging wheel 4. The feeding device and the material arranging mechanism are obliquely arranged, so that the roller can roll into the space between the two rotating rollers 2 through the conveying channel from the hopper 1 by means of self gravity, the two rotating rollers 2 rotate towards the direction of being away from each other, the rotating rollers 2 are matched with the material arranging wheel 4, the posture of the roller is adjusted, and the roller sequentially enters the grinding machine from the material arranging mechanism.

In view of the above-mentioned related art, in an actual situation, when the roller is located in the through groove formed by the rotating roller and the baffle and waits for the material arranging wheel to process, the roller is stacked at the material inlet of the material arranging mechanism, so that part of the roller falls into the gap formed between the material arranging wheel and the baffle, and at this time, the outer end surface of the roller abuts against the baffle and the material arranging wheel respectively. Because the baffle is static and the reason material wheel rotates, and the roller that falls into the space receives other accumulations roller pushes for the roller receives the extruded power towards reason material wheel side, and then makes the roller surface receive reason material wheel friction and impaired, influences product quality.

SUMMERY OF THE UTILITY MODEL

In order to reduce the probability that the friction of a material receiving wheel on the outer surface of a roller is damaged, the application provides a device for preventing a workpiece from being extruded.

The application provides a prevent crowded device that hinders of work piece adopts following technical scheme:

the utility model provides a prevent crowded device that hinders of work piece, is including setting up the nylon piece on the terminal surface that two baffles are close to each other respectively, nylon piece butt is close to in reason material wheel the terminal surface of baffle, just the terminal surface that the live-rollers was kept away from to the nylon piece is higher than the baffle is kept away from the terminal surface of live-rollers.

Through adopting above-mentioned technical scheme, the roller relies on self gravity to fall into the conveying way from the hopper, then gets into two live-rollers of reason material mechanism and press from both sides the passageway of establishing the formation, and two live-rollers are towards the direction circumferential direction of keeping away from each other for the roller keeps the trend of upward movement, and reason material wheel is located the passageway top simultaneously, stirs the roller and carries out the gesture correction, realizes the roller material loading and puts the effect of position. Because there is the space between reason material wheel and the baffle, the roller material loading in-process exists and pushes the condition that gets into the space. Through filling the nylon piece in gap department, when the roller moved towards former gap department, blockked by the nylon piece, the roller also can't block in gap department even by pushing, continues to carry towards the reason material wheel along the live-rollers. The probability of damage caused by friction of the material receiving wheel on the outer surface of the roller is reduced.
