Abstract
The utility model relates to a multipurpose thread surveying instrument which comprises a vernier caliper with a dial indicator and comprehensive measuring heads with the standard tooth pattern. The utility model is characterized in that two external measuring jaws of the vernier caliper are respectively fixed to a measuring base used for clamping the comprehensive measuring heads. At the time of measurement, the utility model is like the vernier caliper to ensure that two measuring heads are tightly engaged by the screw thread measured. Then the indicated value of the ruler plus a constant number is the numerical value of the virtual pitch diameter of the screw thread measured. The utility model has the advantages of simple structure, multiple uses, convenient operation, accuracy of reading and low cost.
Description
This is suitable for novel a kind of instrument of measuring screw thread that relates to.
In whorl work piece was measured, the measurement of screw thread was a difficult point, particularly internal thread at present.In order to address this problem, measure internal thread at known a kind of employing plug thread gauge, but it is to be difficult to realize when measuring the screw thread of large-size, and can not measures the concrete numerical value of footpath on, be not easy on production line, adjust cutter, improve machining precision.
In order to address this problem, the internal thread general measuring instrument that another kind of known employing capacitive displacement transducer is made (" tool technique " that Chengdu Tool Research Institute of dynamo-electric portion edits and publishes 89 years the 9th phase the 38th page), though solved the problem that footpath numerical value shows in the tested threaded function, but because this instrumentation complexity, the cost height, volume and weight is still very big, still can not be used by the workman is on-the-spot on production line, thereby limit its range of application.
The purpose of this utility model is to provide a kind of instrument of measuring screw thread, it is characterized in that it not only can directly read the numerical value of footpath on of tested screw thread, and volume is little, and in light weight, cost is low, and is simple in structure, and workman's execute-in-place is simple and convenient.
The purpose of this utility model is achieved in that a side of measuring jaw outside two of the vernier caliper that has clock gauge, fixes an amount seat respectively, and this amount seat is used for the comprehensive gauge head that clamping has basic-profile.During measurement, as long as the method for using the inside and outside garden of vernier caliper measurement, make two comprehensive gauge heads and tested screw thread tight engagement, this moment, the indicating value of chi added a fixed number, promptly was the numerical value in footpath in the tested threaded function.
This amount seat can be fixed on the outside of the outer measuring jaw of vernier caliper, also can be fixed on the inboard of the outer measuring jaw of vernier caliper.
Above-mentioned amount seat preferably adopts the method for mechanical clamping to come clamping to have the comprehensive gauge head of basic-profile, uses so that accomplish a chi more.
The utility model because only need is fixed an amount seat that can clamping has the comprehensive gauge head of basic-profile on two outer measuring jaws of the vernier caliper of band table, can measure the numerical value directly on of tested screw thread, so simple in structure, easy to use; Simultaneously since clamping to have an amount seat of comprehensive gauge head of basic-profile very easy to use, and owing to have the comprehensive gauge head manufacturing accuracy height of basic-profile, but also can make variety classes, different size, so when measuring the screw thread of variety classes or specification, can realize as long as change corresponding comprehensive gauge head.So the utility model applied range, cost is low, satisfies the requirement of measuring accuracy.
Fig. 1 is the front elevation of screw thread general measuring instrument.
The sectional view of the comprehensive gauge head of Fig. 2 amount of being seat clamping.
Below in conjunction with details and the method for work of accompanying drawing detailed description according to the screw thread general measuring instrument that the utility model proposes.
With reference to Fig. 1: the screw thread general measuring instrument is fixed on amount seat (3) and comprehensive gauge head (4) formation with basic-profile of clamping in amount seat (3) on the outer measuring jaw (2) by the vernier caliper that has clock gauge (1).For guaranteeing the precision of screw thread general measuring instrument, this amount seat is to adopt two outer measuring jaws of adhering method and vernier caliper to be fixed together.As can be seen from Figure 2, the amount seat of present embodiment is fixed together with screw and Γ type link stopper by a rigidity pressing plate and elastic pressing plate and is formed.So not only can clamp comprehensive gauge head, and can also change comprehensive gauge head very easily with basic-profile.During measurement, as long as the method for using the inside and outside garden of vernier caliper measurement, make two gauge heads (4) and tested screw thread tight engagement, this moment, the indicating value of chi added that a fixed number sum promptly is the numerical value of footpath on of tested screw thread.This fixed number is determined after implementing the utility model.That is: comprehensive gauge head (4) clamping that will have a basic-profile is behind amount seat (3), when the indicating value that makes chi is zero, this moment in two comprehensive gauge heads (4) through between distance be the fixed number of this screw thread general measuring instrument.
Claims (3)
1, a kind of screw thread general measuring instrument, it comprises the vernier caliper that has clock gauge, has the comprehensive gauge head of basic-profile, it is characterized in that fixing one on the measuring jaw respectively outside two of vernier caliper is used for the amount seat that clamping has the comprehensive gauge head of basic-profile.
2, screw thread general measuring instrument according to claim 1 is characterized in that being fixed on the outside or the inboard amount seat of outer measuring jaw.
3, screw thread general measuring instrument according to claim 1 and 2 is characterized in that adopting the mechanical means clamping to have the amount seat of the comprehensive gauge head of basic-profile.
