Abstract
The invention discloses a brake shoe circular run-out and perpendicularity comprehensive gauge which can measure the circular run-out and the perpendicularity of brake shoes comprehensively. The comprehensive gauge comprises a rack, a workpiece support and a gauge holder. The workpiece support is connected to the rack rotationally horizontally through a thrust bearing; the workpiece support is provided with a positioning datum plane which is matched with two profiles which are used for matching with the lateral profiles of two brake shoes combined; the gauge holder is detachably connected to the rack and longitudinally provided with at least two dial gauges arranged horizontally; measuring heads of the dial gauges are disposed on arc surfaces of to-be-measured workpieces; the dial gauges are detachably connected to the gauge holder through lock bolts, and horizontal axial displacement of the dial gauges relative to the gauge holder can be regulated through the lock bolts. During use of the comprehensive gauge, the pair of brake shoes is held and fixed to the workpiece support, and then the arc surfaces of the brake shoes can be subjected to comprehensive measurement in terms of circular run-out and perpendicularity through the dial gauges on the gauge holder.
Description
Technical field
The present invention relates to a kind of cubing for automobile brake shoe brake-shoe.
Background technology
Brake-shoe refers to action by brake cam or push rod and is pushed to the outer accessory that braking action is heaved in compacting brake that launches, and is installed on brake drum, is one of breaking piece crucial in brake system of car.Brake-shoe shape is as semilune, and when touching on the brake, the semi-moon shaped brake-shoe of two panels is just lower outside of the effect of wheel cylinder, props up the rub inwall of brake drum of brake-shoe and plays the effect of slowing down or stopping.
Brake-shoe is the vitals of the detents such as motor vehicle, right alignment, the depth of parallelism to automobile normal running and stable braking affect very large.Because brake-shoe is two semicircular body assemblings, do not have appropriate reference face, location, hole after assembling, beating to the circle of brake-shoe and often needing artificial repeated detection in measuring for verticality work, comprehensive detection is more difficult.
Summary of the invention
The invention is intended to provide a kind of brake-shoe circle to beat and verticality comprehensive check tool, to beat to the circle of brake-shoe and verticality carries out the cubing of comprehensive detection to provide a kind of.
Patent formula: the brake-shoe circle in this programme is beated and verticality comprehensive check tool, comprise frame, workpiece support and dial framework, workpiece support is connected in frame by thrust bearing horizontal rotation, workpiece support is provided with the positioning reference plane for coordinating with the two shape faces of filling the span of a man's arms brake-shoe side, dial framework is detachably connected in frame, dial framework is longitudinally provided with the dial gauge of more than two horizontal positioned, the detection head of dial gauge is positioned at the cambered surface of detected workpiece, dial gauge is detachably connected on dial framework by lock-screw, regulate dial gauge relative to the horizontal axis displacement of dial framework by lock-screw.
The feature of technique scheme is: actual and Product processing, assembling handling characteristics according to production line, using the hole of positioning disk φ 192mm bottom brake-shoe, face as positioning datum, design and produce rotary brake-shoe assembling comprehensive check tool.For motor vehicle brake shoe general assembly, detection provide new cubing.During use, a pair brake-shoe workpiece being filled the span of a man's arms is fixed on workpiece support, then can justify brake-shoe curved surface with the dial gauge on dial framework and beat and the comprehensive detection of verticality.
Further, dial framework comprises dial framework guide rail and dial framework montant, and the dial framework guide rail of level is by bolt-connection in frame side, and dial framework montant to be slidably connected on dial framework guide rail and to be fixed by lock-screw.This scheme can unify the transversal displacement regulating multiple dial gauge, is convenient to adapt to difform workpiece.
Further, described workpiece support is the thick middle thin column in perpendicular two up and down of putting.This shape is suitable for coordinating with the intrados of brake-shoe.
Further, dial framework is provided with the equidistant dial gauge of three levels.Middle dial gauge, for detecting the data in the middle part of brake-shoe extrados, coordinates other two dial gauges can complete most of workpiece up and down circle to beat and the comprehensive detection of verticality.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the embodiment of the present invention;
Fig. 2 is the schematic top plan view of the embodiment of the present invention;
Fig. 3 is the partial schematic sectional view of the embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: l-base, 2-workpiece support, 3-dial framework montant, 4-dial framework fastening bolt, 5-dial framework guide rail, 6-guide rail trip bolt, 7-dial gauge, 8-dial gauge trip bolt, 9-bearing locating shaft, 10-thrust bearing, 16-brake-shoe positioning disk, 17-brake-shoe assembly.
Embodiment is substantially as shown in Figure 1, Figure 2 and Figure 3: cubing is connected in the upper surface of base 1 by bearing locating shaft 9 and thrust bearing 10 horizontal rotation by base 1, workpiece support 2, workpiece support 2 and upper brake-shoe assembly 17 to be detected thereof can carry out the revolution of 360 °.
The side of base 1 is connected with the horizontal dial framework guide rail 5 of level by guide rail trip bolt 6, and dial framework montant 3 bottom is provided with the chute mated with dial framework guide rail 5, and dial framework montant 3 to be slidably connected on dial framework guide rail 5 and to be fixed by dial framework fastening bolt 4.The top of dial framework montant 3 is provided with the equidistant slide opening of three levels and wears three dial gauges 7, and the horizontal axis displacement of dial gauge regulates by the dial gauge trip bolt 8 on dial framework.
Brake-shoe assembly 17 loads the round boss that workpiece support mates by φ 192mm hole bottom it, round boss is also diametrically outward 192mm.Be contained in and the dial framework montant 3 on base 1 is equipped with three centimeter check different parts beats, radial run-out and the error of perpendicularity can be read.
In concrete base process, base central bore dress bearing locating shaft, dumpling threaded hole dress dial framework guide rail is bored in milling face, right side, and periphery bores dumpling lifting threaded hole.Workpiece support endoporus dress thrust bearing, head is φ 192mm and processes 30 degree of conical surfaces, is convenient to workpiece loading and unloading.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in instructions etc. record the content that may be used for explaining claim.
