Abstract
A shock absorber wheel hub axle journal burnishing device processing has protruding step on the excircle of wheel hub left side, wheel hub with the inertia ring with the rubber ring assembles an organic whole through pressure equipment mould and constitutes a rubber shock absorber, the rubber shock absorber pass through the bolt with the belt pulley axial is installed and is become a whole at the bent axle front end. The axial movement of the inertia ring is limited on the product assembly by a hub and a pulley, which is independent from the inertia ring as a separate component.
Description
Technical Field
The utility model relates to an automobile manufacturing technical field, in particular to shock absorber wheel hub axle journal burnishing device.
Background
The shaft neck of the shock absorber is matched with an oil seal, the surface roughness requirement is within Ra0.4, the technical requirement can be met only by machining and then polishing, and the currently adopted process method is as follows: after the vibration absorber is clamped on the power head, the polishing belt is held by a hand to perform high-speed relative motion with a shaft neck part to achieve the polishing purpose (as shown in figure 1), and the following problems exist:
1. the operator holds the shaft neck part, and the fatigue or the careless operation under the high-speed rotation condition easily causes the personal safety problem.
2. When an operator holds the oil seal, the finger is pressed by the hand to exert uneven force, the consistency of the overall polishing quality of the matching surface of the shaft neck and the oil seal is not easy to guarantee, and the problem of local oil leakage can be caused by the part which is not polished well.
3. The strip-shaped polishing belt has the problem of waste because the strip-shaped polishing belt cannot be separately utilized by holding.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a shock absorber wheel hub axle journal burnishing device, require the polishing belt of customization standard width according to the width that shock absorber axle journal fitting surface needs polishing, install the polishing belt on the support frame and the axle journal polished surface forms the cornerite, it produces relative motion polishing axle journal surface with it to recycle the high-speed rotation of unit head, the rethread cam device realizes the quickly separating and the laminating of polishing belt and shock absorber axle journal, staff direct contact has both been avoided, the quality homogeneity of the whole polished surface of axle journal has also been guaranteed, and then local oil leak problem behind the installation oil blanket is avoided appearing.
In order to solve the technical problem, the utility model discloses a realize according to following mode: a shock absorber hub journal polishing device comprises a shock absorber driving device (1), a polishing belt driving device (2), a shock absorber (3), a polishing belt (4), a polishing belt and journal clutch device (5) and a polishing belt wrap angle adjusting device (6);
the shock absorber driving device (1) is connected with a central hole of the shock absorber (3) in a positioning mode through a motor mandrel and rotates at a high speed under the driving of motor power; the shaft neck of the vibration absorber (3) and the polishing belt (4) rotate reversely to achieve the polishing purpose; a motor spindle of the polishing belt driving device (2) is matched with a belt wheel to drive the polishing belt (4) to rotate at a uniform speed; the polishing belt and the shaft neck clutch device (5) are connected with a spring device through a cam and move in the horizontal direction to control the polishing belt (4) to be separated from or attached to the shaft neck of the vibration absorber (3); the polishing belt wrap angle adjusting device (6) is connected with a shaft neck of the vibration absorber (3) through the polishing belt (4).
The utility model has the advantages that: 1. the parts are prevented from being directly contacted with the high-speed rotating part by hands, and potential safety hazards are reduced. 2. The consistency of the overall polishing quality of the polished surface is improved. 3. The use efficiency of the polishing belt is improved, and the cost is reduced.
Drawings
FIG. 1 is a schematic view of a prior art machine vibration damper journal burnishing apparatus.
Fig. 2 is a schematic view of an engine damper journal polishing device provided by an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, a shock absorber wheel hub axle journal burnishing device, including shock absorber drive arrangement 1, polishing belt drive arrangement 2, shock absorber (containing the axle journal) 3, polishing belt 4, polishing belt and axle journal clutch 5, polishing belt cornerite adjusting device 6.
Damper drive device 1: the motor core shaft and the central hole of the shock absorber are positioned and driven by the power of the motor to rotate at a high speed.
Polishing belt drive device 2: the polishing belt is driven to rotate at a uniform speed through the matching of the motor spindle and the belt wheel.
3 damper (including journal): the journal and the polishing belt rotate reversely to achieve the polishing purpose.
4, polishing belt: the width of the matching surface of the absorber journal to be polished is required to be customized.
5, a polishing belt and a shaft neck clutch device: the polishing belt is controlled to be separated from or attached to the shaft neck of the vibration absorber through the horizontal movement of the cam and the spring device.
6, polishing belt wrap angle adjusting device: the wrap angle of the polishing belt and the shaft neck part of the shock absorber is controlled by the adjusting device so as to adjust the polishing pressure to be proper.
The present invention is not limited to the above-mentioned preferred embodiments, and any person can obtain other products in various forms under the teaching of the present invention, but any change in shape or structure is made, and all the technical solutions identical or similar to the present invention are within the protection scope of the present invention.
