Abstract
The utility model provides a centerless location terminal surface closing device not only can satisfy the centerless location of work piece, is implementing under the stable effectual location of work piece moreover, and is minimum to the loading power of work piece. The device comprises an upper roller, a lower roller, a workpiece, a supporting block and a positioning plate, and is characterized in that the workpiece 3 is arranged between a pressing rotor 6 and the positioning plate 5, the pressing rotor 6 is positioned in a cylinder body 8, and an opening is formed in the cylinder body 8.
Description
The utility model relates to a kind of workpiece loading positioner, and what be particularly useful for the bearing ring grinding is not in the mood for locating the end face hold down gag.
At present, grinding bearing rings, the mode of workpiece loading location has several, and end face magnetic force loads the location and the workpiece outside loads location etc.After the workpiece loading, yielding, stay residual magnetism and roll the roller marks mark, the accuracy of form and position of workpiece is poor, road processing of influence back and end product quality.
For example: existing 3MZ201,3MZ143 bearing ring grinding out and mill ditch lathe, the location structure that has adopted second wheel one to support exactly, as shown in Figure 1, the last bottom roller of existing structure not only plays the radial location effect, also will play the axial thrust effect.For workpiece spindle to being positioned on the location-plate, special axis and axis of workpiece with second wheel is the β angle, when making the pair of rollers workpiece make radial loaded, produces an axial thrust load, the promotion workpiece relies on location-plate, finishes axial location.Because roller and workpiece axle center are not parallel, cause the side bus of roller and the side bus of workpiece not to coincide, and are a contact condition, the stability of its location must be lower than the line stability in contact.Especially when the inner ring grinding out, existing structure can not be implemented the Zhigou location, causes the hole of inner ring and inner ring outer fissure wall thickness deflection big.Because workpiece will obtain axial location component, it is making a concerted effort of radial component and axial thrust load that workpiece is subjected to the loading force of roller again, and it must want big with joint efforts, cause the workpiece discontinuity, yielding, the stress point place produces tangible impression, the accuracy of form and position of workpiece after the difficult raising grinding.
The purpose of this utility model is, a kind of end face hold down gag of not being in the mood for locating is provided, and not only can satisfy the location of not being in the mood for of workpiece, and implement under the stabilizing effective location of workpiece, to the loading force minimum of workpiece.
The purpose of this utility model can reach by following measure:
A kind ofly be not in the mood for locating the end face hold down gag, comprise upper roller, bottom roller, workpiece, rest pad, location-plate, it is characterized in that workpiece 3 between compressing between rotor 6 and the location-plate 5, compresses rotor 6 and is positioned at cylinder body 8, perforate on the cylinder body 8.
The purpose of this utility model can also reach by following measure:
Compress rotor 6 and in cylinder body 8, make axial back and forth movement;
At least have two holes on the cylinder body 8.
The utility model has the advantages that:
The axis of bottom roller is all parallel with the bistrique axis with workpiece on the utility model, the side bus of roller and the side bus of workpiece in the same way, and two buses can fit like a glove, and make that outer garden of workpiece or the outer trench culture of workpiece location baseline stability are reliable.Compress rotor under the effect of hydraulic pressure, it is constant and stressed evenly to make axial loading force to workpiece.Workpiece is subjected under the constraint of the utility model structure, and rotation is steady, the location is constant, provides good condition for emery wheel enters the grinding state.Make the inner ring endoporus of grinding and outer ring septal fossula not garden degree, wall thickness difference and with the end face vertical difference, can be reduced to minimum.
From the advantage of above-mentioned analysis the utility model structure, apparently higher than existing structure, the grinding accuracy new construction of workpiece is higher than old structure.
Fig. 1 is the axial positioning structure schematic diagram of existing apparatus to workpiece.
What Fig. 2 was the utility model to workpiece radially is not in the mood for locating schematic diagram.
Fig. 3 is the axial positioning structure schematic diagram of device of the present utility model to workpiece.
The utility model is described in further detail below in conjunction with accompanying drawing:
When 1 pair of workpiece 3 of upper roller adds load.Workpiece 3 is by upper and lower roller 1,2 radial locations, and rotation is synchronously done in drive.After workpiece 3 has been finished radial location and grinding rotation, hydraulic pressure is imported and exported to cylinder body 8 and is acted on F1, F2 respectively, when the F1 supercharging, during the F2 decompression, hydraulic pressure F1 promotes to compress rotor 7 and does axially-movable, compresses 7 pairs of workpiece 3 of rotor and axially loads, and makes workpiece 3 abut against on the location-plate 4, workpiece 3 is finished axial location, compresses rotor 7 simultaneously and is also driven do rotation synchronously by workpiece 3.Like this, workpiece 3 is rotated by comprehensive location and grinding, and loading force invariable after, emery wheel 6 advances level and enters the grinding state.Grinding finishes, and by the above-mentioned counteragent of doing successively, workpiece 3 withdraws from from station, finishes the grinding actuation cycle of a workpiece.Owing to adopt such scheme, the radial loaded power of workpiece 3 is exceeded to drive workpiece 3 rotations, axially loading force exceeds near location-plate 4 with workpiece 3.Therefore, loading force can be accomplished minimum, keeps constant, and control is convenient, removes a year back workpiece 3 is not stayed surplus energy.
Claims (3)
1, a kind ofly is not in the mood for locating the end face hold down gag, comprise upper roller, bottom roller, workpiece, rest pad, location-plate, it is characterized in that workpiece (3) between compressing between rotor (6) and the location-plate (5), compresses rotor (6) and is positioned at cylinder body (8), cylinder body (8) is gone up perforate.
2, according to claim 1ly be not in the mood for locating the end face hold down gag, it is characterized in that compressing rotor (6) and in cylinder body (8), make axial back and forth movement.
