Description

Columnar part grinding device

Technical Field

The utility model belongs to the technical field of auto parts makes, a column part grinding device is related to.

Background

With the development of society, the technology is continuously improved, the economic level is continuously improved, the living conditions of people are better and better, more and more automobiles are used for walking instead of walk, and the automobile part processing market competition is intensified along with the civilization of automobiles.

Automotive parts are typically made by casting, stamping, etc. because of the high temperatures involved in operation, the parts will be molten during processing and then solidify. Therefore, the part is after processing is accomplished, and the unsmooth burr of unevenness can appear on the cylindrical surface of part, and the column part also can produce corrosion or unsmooth burr in long-term use simultaneously.

Traditional car axle class part is polished mostly hand-held type and is polished, and when hand-held part polished, long-time work, arm ache made the part take hold between the fingers insecure, influence the work of polishing, and the while manpower is polished wayward dynamics, causes part surface unevenness, and it is inhomogeneous to polish. Secondly, use mechanical assistance's semi-automatic grinding device to carry out the part and polish, current column part grinding device is often fixed with the part through the tight mode of clamp to the part outer wall, the in-process of polishing like this, for avoiding the clamping part of part not polished, need incessantly alternate the clamping part of part, the centre gripping has increased operating procedure repeatedly, the process velocity that also slows down, and still need control part or the piece transform direction of polishing, just can guarantee polishing to each position of part surface, only can polish a part on the surface of part like this, can not once only accomplish the work of polishing to the part surface, waste time and energy.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a column part grinding device accomplishes the location to the part, solves the problem that need relapse the centre gripping and the area of polishing is little when polishing to the part, realizes evenly polishing to the part surface simultaneously.

In order to achieve the above object, the basic scheme of the utility model is: the utility model provides a column part grinding device, includes at least one board of polishing and to the positioning mechanism of part location, the face of polishing of one board of polishing is up for place the part, and the board of polishing is connected with control its actuating mechanism around part surface pivoted, and the board of polishing and the laminating of part surface, positioning mechanism includes ejector pin and baffle, the ejector pin is located the board one side of polishing, and the ejector pin is connected with the control mechanism who controls its sharp intermittent type nature reciprocating motion, the baffle is located the one side that the ejector pin was kept away from to the board of polishing.

The working principle and the beneficial effects of the basic scheme are as follows: the part can be placed to the board of polishing self, need not to set up and places the device that the part was placed to platform etc. simplifies the device structure, has practiced thrift manufacturing cost. The drive mechanism can order about the board of polishing and rotate, fixes a position the back at the mechanism to the part, and the board of polishing rotates and the part is fixed, and the part surface laminating when polishing board and location in addition can produce relative friction with the board of polishing, accomplishes the abundant polishing to the whole axle body of part. The position relation between board and the part of polishing is unchangeable all the time, and the effect dynamics of each other is unchangeable, compares with manpower control dynamics of polishing or the angle of polishing, polishes more evenly. Meanwhile, the shaft body of the part can be comprehensively polished without changing the angle of the polishing plate or the position of the moving part, so that the operation is simpler, and the polishing speed is accelerated.

The ejector pin is controlled by control mechanism and follows straight line intermittent type nature reciprocating motion, and control mechanism control ejector pin removes to baffle place one side, accomplishes the location until the part, and control mechanism control ejector pin keeps this state for a certain time this moment, then just drives the ejector pin and resets, is so for at the in-process of polishing, makes the ejector pin offset with the part all the time, guarantees that the location is stable, provides abundant polishing time and after polishing the completion, the ejector pin just controlled by control mechanism and reset.

Furthermore, the baffle is located between the grinding plates, one side of the baffle, which is far away from the ejector rod, is connected with a supporting piece for keeping the baffle moving linearly between the grinding plates, and an elastic piece is arranged between the baffle and the supporting piece.

The supporting piece ensures that the baffle and the ejector rod are always in relative positions, and the supporting force of the elastic piece on the baffle is avoided being insufficient. The elastic piece can play the cushioning effect, produces hard collision and causes the damage when avoiding part and baffle to offset. Simultaneously, different extrusion degrees of the elastic part have different displacements, so that the device can position and polish parts with different lengths in a certain range on the premise of not moving other devices. And after polishing, the elastic part resets to drive the baffle to reset, thereby pushing the part to the polishing plate for a certain distance, and facilitating the taking out of an operator. Simultaneously, the elastic part can apply reaction force to the part through the baffle plate to limit when being extruded, so that the baffle plate and the part are extruded more tightly when being positioned, and the stability when being positioned is enhanced.

Furthermore, the supporting piece is far away from one end of the baffle and is fixedly connected with a clamping block, the side edge of the supporting piece is provided with a plurality of clamping grooves clamped with the clamping block, and when the clamping is carried out, the clamping block is attached to the inner wall of each clamping groove.

The fixture block on the support piece is connected with the clamping grooves in different positions, the position of the support piece can be moved, the support piece is connected with the baffle, the baffle can be driven to move simultaneously, the distance between the baffle and the ejector rod is controlled, the distance between the ejector rod and the baffle plate is adjusted and positioned, the length of the part to be polished is determined, and polishing of the part with different lengths in a larger range is achieved.

Further, actuating mechanism includes second power supply and connecting rod, the second power supply is located the baffle and keeps away from the one side of accepting the board, connecting rod one end is connected with the output of second power supply, and the other end can be dismantled with the board one side of being close to the baffle of polishing and be connected.

The second power supply can be through connecting rod control board rotation of polishing, and the board of polishing can be dismantled with the connecting rod and be connected, when the board damage of polishing or the board of polishing and part size mismatch, is convenient for dismantle the change to the board of polishing.

Furthermore, the push plate is fixedly connected with one end, close to the rotating shaft, of the ejector rod, the push plate is opposite to the baffle, and the length and the width of the push plate are both smaller than the diameter of the part.

The area that the face and part contacted is bigger, more does benefit to and promotes the part, avoids causing the roof pressure damage to the part terminal surface. The size of the push plate is limited so as to avoid the situation that the push plate cannot extend into the polishing plate and cannot push and position the part.
