Abstract
Mar measuring apparatu relates to a measured depth's precision instruments, belongs to the degree of depth and measures the field. When measuring the workpiece surface mar degree of depth, arouse operate miss and reading error's problem easily. Mar measuring apparatu, it includes amesdial, fixing base and contact pilotage, the fixing base is hollow cylinder, and the hollow cylinder bottom surface is the opening side, and the center department of hollow cylinder top surface opens there is the centre bore, the amesdial is fixed on the top surface of fixing base, the one end of contact pilotage is fixed on the measuring stick of amesdial, and the other end of contact pilotage passes behind the centre bore flaggingly naturally. The beneficial effects of the utility model are that this mar measuring apparatu can the completed workpiece surface scratch high precision measurement, measurement accuracy can reach 0.01mm, this mar measuring apparatu simple structure, convenient to use, amesdial can direct readout numerical value, reduce measuring error, be applicable to the measurement to the mar degree of depth.
Description
Technical field
The utility model relates to a kind of precision instrument measuring the degree of depth, belongs to depth survey field.
Background technology
Current equipment manufacture is constantly in development, and process for processing level constantly promotes, and the precision of product is progressively improving; The roughness of accurate equipment Requirement part machined surface is extremely high, the scratch depth of machined surface directly affects the accuracy of assembling entirety, so the measurement of scratch depth, the evaluation of final cut is very important, the proposition of process cut scheme there is is great meaning. Prior art Problems existing: when using screw micrometer to measure scratch depth, need measurement twice, first time measures the thickness that workpiece does not have cut position, second time measures the thickness at cut position, after twice measuring result does difference, drawing scratch depth, screw micrometer reading is inconvenient, and easily produces operate miss and reading error.
Practical novel content
When the purpose of this utility model is to measure workpiece surface scratch depth, it is easy to cause the problem of operate miss and reading error, it is proposed to a kind of cut survey meter.
Cut survey meter described in the utility model, it comprises dial indicator, permanent seat and contact pilotage;
Permanent seat is open circles cylinder, and open circles cylinder bottom surface is open side, and the center of open circles cylinder end face has centre hole;
Dial indicator is fixed on the end face of permanent seat;
One end of contact pilotage is fixed on the thief rod of dial indicator, and the other end of contact pilotage naturally droops after centre hole.
Cut survey meter using method described in the utility model is: be placed on horizontal plane by workpiece, the cut measured is needed to be positioned at workpiece surface, then this cut survey meter is lain in a horizontal plane on workpiece, ensure that the lower surface of contact pilotage and permanent seat is in same level, dial indicator pointer is regulated to return " 0 ", mobile cut survey meter is to cut place, due to the gravity of contact pilotage self, pull thief rod, dial indicator is made to have certain reading, dial indicator reading is the distance that dial indicator thief rod moves, and is the degree of depth of workpiece cut.
The beneficial effects of the utility model are the high precision measurements that this cut survey meter can complete workpiece surface cut, and measuring accuracy can reach 0.01mm; This cut survey meter structure is simple, it may also be useful to convenient, can reduce operate miss during measurement, dial indicator can direct readout value, minimizing measuring error; It is applicable to the measurement to scratch depth.
Accompanying drawing explanation
Fig. 1 is the cut survey meter structural representation described in embodiment one;
Fig. 2 is the structural representation during measurement of the cut survey meter described in embodiment one;
Fig. 3 is the structural representation of permanent seat in embodiment two.
Embodiment
Embodiment one: composition graphs 1 and Fig. 2 illustrate present embodiment, the cut survey meter described in present embodiment, it comprises dial indicator 1, permanent seat 2 and contact pilotage 3;
Permanent seat 2 is open circles cylinder, and open circles cylinder bottom surface is open side, and the center of open circles cylinder end face has centre hole 5;
Dial indicator 1 is fixed on the end face of permanent seat 2; It is convenient to dial indicator 1 is carried out reading operation;
One end of contact pilotage 3 is fixed on the thief rod of dial indicator 1, and the other end of contact pilotage 3 naturally droops after centre hole 5; Ensure being " 0 " to the reading of dial indicator during plane surveying 1.
Time unmeasured as shown in Figure 1, the other end of contact pilotage 3 is positioned on open circles cylinder bottom surface, and the reading of dial indicator 1 is zero; During measurement as shown in Figure 2, workpiece 4 is placed on horizontal plane, the cut measured is needed to be positioned at workpiece 4 upper surface, then this cut survey meter is lain in a horizontal plane on workpiece 4, ensure that the lower surface of contact pilotage 3 and permanent seat 2 is in same level, dial indicator pointer is regulated to return " 0 ", mobile cut survey meter is to cut place, due to the gravity of contact pilotage 3 self, pull thief rod, making dial indicator 1 have certain reading, dial indicator 1 reading is the distance that dial indicator thief rod moves, and is the degree of depth of workpiece 4 cut.
Embodiment two: composition graphs 3 illustrates present embodiment, present embodiment is limited further by the cut survey meter described in embodiment one, in the present embodiment, the lower end of permanent seat 2 sidewall has N number of observation port 6, and N number of observation port 6 is uniformly distributed along permanent seat 2 sidewall; Observation port 6 is for observing the position residing for contact pilotage 3.
Described N >=2.
Embodiment three: present embodiment is limited further by the cut survey meter described in embodiment two, in the present embodiment, N=4. Observed by four observation ports, it is possible to from four different angles observation contact pilotages 3, observation angle more comprehensively, not easily produces error.
