Abstract
The utility model discloses a static balance detection device of a brake drum and a wheel hub, aiming at solving the technical problems of complicated operation of the detection device and low detection efficiency of the existing equipment. The static balance detection device of the brake drum and the wheel hub comprises a bracket (5) and bearings (7), wherein the two bearings (7) are internally and movably provided with main shafts (6) along the horizontal direction; the two ends of the main shafts (6) respectively extend outside the outer side of the bracket (5); the left ends of the main shafts (6) are fixedly connected with a rotary disc (18), a flange plate (2) and a chuck (1); the chuck (1) is blocked and connected with the measured brake drum; a shaft at the right ends of the main shafts (6) is movably sheathed and connected with a measuring rod (14); the middle part of the measuring rod (14) is fixed at the right ends of the main shafts (6) by a puller bolt (12); and one end of the measuring rod (14) is provided with a balance weight block (11), and the other end thereof is provided with a balance block (13). The utility model provides an accurate detection method for detecting whether the blank casting of the automobile brake drum is even or not.
Description
Technical field
The present invention relates to a kind of balance detecting device that detects heavy castings, particularly a kind of to circular casting workpiece, as the static balance testing device of the brake drum of automobile, wheel hub, brake disc, spoke wheel spray.
Background technology
Existing static balance testing device is guide tracked static equilibrium instrument, roller type static equilibrium instrument, be earlier workpiece to be placed on the equilibristat, rotate gently, when being in extreme lower position, its barycenter just can stop, again rotate in the opposite direction correction up balance mass of barycenter this moment again, increases and decreases balance mass repeatedly, until being the indifferent equilibrium state, promptly rotor reaches static equilibrium.There is the shortcoming of the loaded down with trivial details and counterweight complicated operation of clamping workpiece in prior art.
Summary of the invention
The static balance testing device of brake drum provided by the invention, wheel hub has solved the pick-up unit complicated operation that existing equipment exists, the technical matters that detection efficiency is low.
The present invention overcomes the above problems by following scheme:
Brake drum, the static balance testing device of wheel hub, comprise support, the bearing that two ends on the same surface level of support are provided with respectively, in bearing, be provided with bearing holder (housing, cover), in two bearings, be movably set with the main shaft of horizontal direction, the two ends of main shaft reach the outside of support respectively, the left end of main shaft is fixed with rotating disk, rotating disk is fixed together by first bolt and ring flange, ring flange is fixed together by second bolt and chuck, on chuck, be connected with tested brake drum, movable sleeve is connected to sounding rod on the axle of the right part of main shaft, and the middle part of sounding rod is provided with the hole that the right part axle for main shaft passes, and puller bolt is fixed on sounding rod the right-hand member of main shaft, end at sounding rod is provided with balancing weight, is provided with counterbalance weight at the other end of sounding rod.Chuck is provided with backstay, and backstay is fixed on the chuck by the 3rd set bolt, and tested brake drum is connected on the backstay.
Whether the present invention evenly provides accurate test method to the rough-cast of automobile brake drum, guarantees that the blank of automobile brake drum is produced turning quality, and mechanism is simple to operate, changes easy to maintenance.

Embodiment
Brake drum, the static balance testing device of wheel hub, comprise support 5, the bearing 7 that two ends are provided with respectively on the same surface level of support 5, in bearing 7, be provided with bearing holder (housing, cover) 8, in two bearings 7, be movably set with the main shaft 6 of horizontal direction, the two ends of main shaft 6 reach the outside of support 5 respectively, the left end of main shaft 6 is fixed with rotating disk 18, rotating disk 18 is fixed together with ring flange 2 by first bolt 4, ring flange 2 is fixed together with chuck 1 by second bolt 3, on chuck 1, be connected with tested brake drum, movable sleeve is connected to sounding rod 14 on the axle of the right part of main shaft 6, and the middle part of sounding rod 14 is provided with the hole that the right part axle for main shaft 6 passes, and puller bolt 12 is fixed on sounding rod 14 right-hand member of main shaft 6, end at sounding rod 14 is provided with balancing weight 11, is provided with counterbalance weight 13 at the other end of sounding rod 14.Chuck 1 is provided with backstay 16, and backstay 16 is fixed on the chuck 1 by the 3rd set bolt, and tested brake drum is connected on the backstay 16.
The present invention has mainly utilized the steelyard principle.Arrive clamping workpiece above the scroll chuck of static equilibrium cubing earlier during operation, with the light turning of work piece of have gentle hands, when its barycenter is in extreme lower position and stops operating, the end that counterbalance weight 13 is housed above the sounding rod 14 is forwarded on the phase places that become 180 degree with the workpiece barycenter, lock puller bolt 12 again.Forward the workpiece barycenter to horizontal level with hand, it is the opposite that sounding rod 14 and counterbalance weight 13 forward workpiece barycenter horizontal level to, adjust the position of the counterbalance weight 13 above the sounding rod 14, if workpiece barycenter and sounding rod can both continue to keep horizontal level, just then above the sounding rod 14 scale display positions at counterbalance weight 13 places numerical value be the static equilibrium amount of workpiece.
The production scene is not owing to there is suitable blank static balance testing device, spray is not often done static equilibrium and is detected and proofread and correct, only start balance detection and correction after machining, aequum can not be proofreaied and correct by mechanical processing process, causes a part of product to scrap because aequum is overproof; And the blank that does not pass through balance detection and correction is easy to generate vibration and noise when machining, and is bigger to equipment and operator's harm.
