Abstract

The utility model relates to a workpiece detecting device, in particular to a detecting device used for detecting ball diameter of a spherical gasket. The device comprises a framework which is composed by a bottom plate, a middle plate, an upper plate and two side guide pillars, wherein the middle plate is in sliding connection with the guide pillars; the middle part of the upper plate is in threaded connection with a threaded pressing head, the middle part of the middle plate is provided with a pressure sensor with a digit display meter, the bottom plate is fixed with a concave die, a convex die with the same ball diameter is arranged above the concave die, the lower end of the threaded pressing head is pressed on a pressure-bearing surface of the pressure sensor, the lower end of the pressure sensor is in contact with the upper surface of the convex die, and the upper surface of the convex die is provided with a dial indicator used for measuring the height of the convex die. The ball diameter detecting device utilizes the pressure sensor to apply a standard load on the workpiece, fully simulates the application state, is accord with test specifications of standard requirements, and ensures the conformity and stability of test qualified products; and the ball diameter detecting device has the advantages of being simple in structure and convenient in operation, and being easy to master by the operator, and lays the foundation for ensuring the normal batch production of products.

Description

Spherical pad sphere diameter pick-up unit

Technical field

The utility model relates to Workpiece detecting device, is specifically related to a kind of pick-up unit for detection of spherical pad sphere diameter.

Background technology

Spherical pad (planetary gear pad) is widely used on automobile differential, coordinate with planet wheel, after need to processing, surface has high-wearing feature, its sphere diameter size is used most important for assembling, present stage, its detection means mainly contained two kinds-three-dimensional coordinates measurement and red powder polishing, and the former cost-effective rate is low, was unfavorable for batch production, the latter and standard compliance are poor and operator's technical ability is had relatively high expectations, also non-optimum way.

Summary of the invention

The problem existing for above-mentioned two kinds of measuring methods, the utility model provides a kind of spherical pad spherical diameter measurement device, utilizes pressure head and pressure transducer to apply normal loading to workpiece, and simulation detects workpiece with state, easy to operate.

The spherical pad sphere diameter pick-up unit that the utility model provides, comprise by base plate, in the framework that forms of plate, upper plate and both sides guide pillar, middle plate and guide pillar are slidably connected; Upper plate intermediate thread is connected with band silk pressure head, in the middle of middle plate, be provided with the pressure transducer with registration table, on base plate, be fixed with die, die top is provided with the punch identical with its sphere diameter, band silk pressure head lower end withstands on pressure transducer pressure-bearing surface, pressure transducer lower end contacts with punch upper surface, and punch upper surface place is provided with for measuring the dial gauge of punch height.Workpiece for measurement is put in the middle of die and punch, rotating band silk pressure head, pressure transducer and punch are exerted pressure, by pressure transducer, observe the value of exerting pressure, until reach normal loading, by dial gauge record exert pressure before and after the difference in height of punch upper surface, and with setting value comparison, know whether the sphere diameter of workpiece for measurement meets standard.If workpiece for measurement and standard sphere diameter meet substantially, before and after exerting pressure, dial gauge registration is substantially constant; Otherwise dial gauge registration changes greatly.

In order to make this device can be applicable to the detection of the spherical pad of various sphere diameters, described die and punch are provided with multipair, have different sphere diameters, select the die and the punch that match with it according to the sphere diameter of tested pad.

The utility model utilizes pressure transducer to apply normal loading to workpiece, simulates use state completely, meets the test specification of standard-required, accordance and the stability of the product that guarantees to be up to the standards; The utility model is simple in structure, easy to operate, and the easy left-hand seat of operator, for the normal batch production of assurance product is laid a good foundation.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment;

In figure, 1, base plate, 2, bolt, 3, die, 4, punch, 5, guide pillar, 6, middle plate, 7, pressure transducer, 8, registration table, 9, upper plate, 10, a band silk pressure head, 11, dial gauge.

Embodiment

A sphere diameter pick-up unit, as shown in Figure 1, comprise by base plate 1, in the framework that forms of plate 6, upper plate 9 and both sides guide pillar 5, middle plate 6 is slidably connected with guide pillar 5; Upper plate 9 intermediate thread are connected with band silk pressure head 10, in the middle of middle plate 6, are provided with the pressure transducer 7 with registration table 8, are fixed with die 3 on base plate 1, and die 3 bottoms are provided with threaded hole, and base plate 1 is provided with bolt 2, is bolted die 3.Die 3 tops are provided with the punch identical with its sphere diameter 4, and band silk pressure head 10 lower ends withstand on pressure transducer 7 pressure-bearing surfaces, and pressure transducer 7 lower ends contact with punch 4 upper surfaces, and punch 4 upper surface places are provided with for measuring the dial gauge 11 of punch height.Described die and punch are provided with multipair, have different sphere diameters, select the die and the punch that match with it according to the sphere diameter of tested pad.

During use, according to the sphere diameter of pad to be measured, select corresponding die and punch, die is contained on base plate, pad to be measured is placed in die, punch is contained between die and pressure transducer, in adjustment, plate height makes pressure transducer contact with punch upper surface, reads the registration of dial gauge again.Rotating band silk pressure head, observes pressure sensor reading until reach normal loading, now reads dial gauge registration again.If twice of front and back numerical difference between is in range of set value, pad sphere diameter to be measured meets standard, otherwise, do not meet.
