Abstract
The invention discloses a drum brake and hub static balance testing device and solves the technical problems of complex operation and low test efficiency of the test device of the conventional equipment. The device comprises a bracket (5) and bearings (7), wherein horizontal main shaft (6) is arranged in the two bearings (7); both ends of the main shaft (6) extend to the outer side of the bracket (5); the left end of the main shaft (6) is fixedly connected with a rotating disc (18), a flange plate (2) and a chuck (1) which is connected with a tested drum brake; the right end part of the main shaft (6) is movably sleeved with a measuring rod (14); the middle part of the measuring rod (14) is fixed at the right end of the main shaft (6) by a pressing bolt (12); and one end of the measuring rod (14) is provided with a counterweight (11), while the other end is provided with a balance weight (13). The device provides an accurate test method for the casting uniformity of the blank of the automotive drum brake.
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, like 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 appearance, roller type static equilibrium appearance, is earlier workpiece to be placed on the equilibristat, rotates gently;, its barycenter just can stop when being in extreme lower position; 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 through following scheme:
The static balance testing device of brake drum, wheel hub comprises support, the bearing that the 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, and rotating disk is fixed together through first bolt and ring flange, and ring flange is fixed together through 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 that supplies 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 through 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
The static balance testing device of brake drum, wheel hub comprises 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, and rotating disk 18 is fixed together with ring flange 2 through first bolt 4, and ring flange 2 links together together through second bolt 3 and chuck 1 surely; 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 that supplies 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 through 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 place that becomes 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; The position of the counterbalance weight 13 above the adjustment 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 place 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 through 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.
