Abstract
The invention discloses a reverse assembly detection device and a reverse assembly detection method for a conical roller bearing inner ring assembly. The reverse assembly detection device comprises a base, a columnar core shaft with an annular step, and one or two groups of adjusting stop block and bolt combinations; the columnar core shaft comprises an upper small core shaft, a lower large core shaft and the middle annular step; the lower end of the columnar core shaft is fixedly connected with the base, and the columnar core shaft and the base are mutually vertically arranged; and the adjusting stop block is positioned on one side of the columnar core shaft with the step and connected with the base by bolts in a proper distance. The small end of a product to be detected is put on the annular step of the columnar core shaft, and an operator rotates the product by hand; if the product can rotate in a whole ring, the assembly of the product is normal; if the product collides with the large end of the conical roller and is blocked by the adjusting stop block so as not to rotate in the whole ring, the conical roller is reversely assembled. The reverse assembly detection device has the advantages of simple structure, convenient debugging and operation, strong practicability and high detection efficiency, ensures full reliable detection, and ensures the quality of the product.
Description
Technical field
The present invention relates to a kind of conical roller bearing inner ring assembly pick-up unit and detection method, particularly relate to anti-pick-up unit and the detection method adorned of a kind of conical roller bearing inner ring assembly.
Background technology
Conical roller bearing inner ring assembly is made up of conical inner ring, retainer and conical roller, shown in Fig. 3 (A), (B).In the cone assembly assembling process, because factors such as lathe frock or workmans, the possibility of the anti-dress of conical roller can appear inevitably, the big end of just conical roller and small end is counter adorns is shown in Fig. 4 (A), (B).So conical roller bearing inner ring assembly must have the detection operation one after assembling, the anti-conical roller bearing inner ring assembly of adorning all must be checked.
At present, the detection means of the most of Production of bearing of China producer is that naked eyes detect.But whether anti-naked eyes detect conical roller dress, omission easily.Because in hand-turning, may rotate not exclusively at conical roller bearing inner ring assembly; Or the operation in night, light is bad, or because range estimation for a long time causes operator's visual fatigue, or certain situation takes place on every side, the negligence between new line all may cause omission, thereby has a strong impact on product quality.In case this type of situation occurs, the quality accident that causes is fatal often, not only influences the reputation of enterprise, and may bring irremediable loss to the client.
Summary of the invention
The objective of the invention is in the above-mentioned prior art, whether anti-naked eyes detect conical roller dress, omission easily, have a strong impact on the defective of product quality, a kind of pick-up unit of simple in structure, easy to operate, practicality and high efficiency is provided, has guaranteed to detect reliable fully, guaranteed product quality.
The technical scheme taked of the present invention is to achieve these goals: the anti-pick-up unit of adorning of a kind of conical roller bearing inner ring assembly, comprise base, the right cylinder core axle that also comprises a band shape step, and 1 or 2 group regulated block and screw combination, right cylinder core axle comprises the top small core shaft, the big mandrel in bottom and a circular step, the inner ring diameter of bore of top small core shaft diameter and detected taper roll bearing inner ring assembly is complementary, the inner ring endoporus of taper roll bearing inner ring assembly can be enclosed within on the small core shaft of top, be rotationally connected with the top small core shaft, circular step is between the big mandrel of top small core shaft and bottom, fixedly connected with base in the lower end of right cylinder core axle, orthogonal installation, regulate the side of block at the right cylinder core axle of band shape step, with base is that screw is connected, distance between the right cylinder core axle of described adjusting block and band shape step, should be greater than the contact point of the normal component location guide conical roller of its top and detected position distance to the right cylinder core axle of band shape step, less than the contact point of the conical roller of anti-dress of its top and detected position distance to the right cylinder core axle of band shape step.So the moving range L of adjusting block equals the distance between above-mentioned two contact points.
Comprise that 2 groups are regulated block and screw combination, in the right cylinder core axle symmetria bilateralis setting of band shape step.
Make up corresponding place with adjusting block and screw on the described base screw hole is arranged, adjusting block middle part is provided with two ends has elongate slot with the level for semicircle, middle part, screw is through regulating the elongate slot of block, is connected with screw hole screw on the base.
The height of described adjusting block should make the contact point of the conical roller of its top and detected position, at the 1/3-1/4 place of conical roller by the bottom.
The height of described adjusting block should make the contact point of the conical roller of its top and detected position, at 1/4 place of conical roller by the bottom.
Distance between the right cylinder core axle of described adjusting block and band shape step ", equal the intermediate value of " regulating the distance of the contact point of block top and the normal component location guide conical roller of detected position " and " contact point of the conical roller of anti-dress of adjusting block top and detected position is to the distance of the right cylinder core axle of band shape step " to the right cylinder core axle of band shape step.
The shape at described adjusting block top can be rectangle, half round post or prismatic.
Described adjusting block top be shaped as rectangle.
The anti-pick-up unit detection method of adorning of a kind of conical roller bearing inner ring assembly, this technology comprises the steps:
(1) equipment is installed: the right cylinder core axle of a band shape step is fixed on the base, and orthogonal installation is regulated block to 2 and tentatively is installed on the base of right cylinder core axle both sides by screw, is symmetrical arranged;
(2) equipment debugging: slightly unclamp screw; Model according to conical roller; Regulate block respectively on its elongate slot with the level for 2; Adjust to suitable position; Make regulate block and with the distance between the cylindrical mandrel of ring-type step "; Equal the median of " contact point of regulating block top and the normal component location guide conical roller of detected position is to the distance with the cylindrical mandrel of ring-type step " and " contact point of the conical roller of anti-dress of adjusting block top and detected position is to the distance with the cylindrical mandrel of ring-type step "
Screw is fixing slightly;
(3) unit check: test with the normal conical roller bearing inner ring assembly of 2-5 spare, its small end is put into the top small core shaft of right cylinder core axle, to circular step, rotate product by hand, can put in order circle and rotate, test with the conical roller bearing inner ring assembly of the anti-dress of 2-5 spare again, its small end is put into the top small core shaft of right cylinder core axle, to circular step, rotate product by hand, can not put in order circle and rotate;
(4) equipment is fixed: the screw-driving of both sides, regulate block to 2 and pass through screw, the distance between the last right cylinder core axle on request and band shape step is installed on the base of right cylinder core axle both sides;
