The utility model discloses an internal diameter plug can examine internal diameter size and straightness accuracy simultaneously, and the effectual problem of avoiding prior art existence only examines once and just can judge whether internal diameter size and straightness accuracy meet the regulation requirement, has greatly shortened check-out time.
Description
Technical Field
The utility model relates to an automobile engine pipe fitting technical field, concretely relates to internal diameter plug for automobile engine pipe fitting.
Background
In the prior art, each customer has different requirements on products, some customers require straightness inspection, some customers require inner diameter dimension inspection, and some customers require both inner diameter dimension and straightness inspection.
The existing solution is to check the inner diameter size and then check the straightness. In actual production, if a large quantity of products adopt the inner measuring micrometer to measure the inner diameter one by one and the marble platform and the feeler gauge to measure the linear one by one, manpower, material resources and financial resources are wasted.
In the prior art, the inner diameter size and the straightness of a product are inspected by two procedures, so that certain time and labor are wasted, and the problem of missed inspection is easily caused due to the fact that the speed is too high when the straightness is inspected.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model aims to provide an automobile engine is internal diameter plug for pipe fitting to reach quick effectual detection purpose.
In order to realize the utility model discloses an aim, the technical scheme who adopts is:
the utility model provides an internal diameter plug for automobile engine pipe fitting, includes one and detects handheld end, detect handheld end with detect plug integrated into one piece, the external diameter that detects the plug is less than the internal diameter of the product that awaits measuring, the length that detects the plug is greater than the length of the product that awaits measuring, detect the plug with the external diameter that detects the junction of handheld end is less than the internal diameter of detecting the plug.
In a preferred embodiment of the present invention, the joint between the detection core rod and the detection handheld end is concave and frosted.
In a preferred embodiment of the present invention, the inner diameter mandrel is made of Cr12Mov and has a hardness in the range of HRC 52-56 °, and the inner diameter mandrel is formed by vacuum heat treatment.
The beneficial effects of the utility model reside in that:
the utility model discloses an internal diameter plug can examine internal diameter size and straightness accuracy simultaneously, and the effectual problem of avoiding prior art existence only examines once and just can judge whether internal diameter size and straightness accuracy meet the regulation requirement, has greatly shortened check-out time.
Drawings
Fig. 1 is a schematic structural diagram 1 of the present invention.
Fig. 2 is a schematic structural diagram 2 of the present invention.
Detailed Description
The structure and operation of the present invention will be further explained by the following embodiments.
The inner diameter mandrel 100 for the automobile engine pipe fitting shown in fig. 1 comprises a detection mandrel 110 and a detection handheld end 120 which are connected together and are convenient to operate during detection, wherein the detection handheld end 120 and the detection mandrel 110 are integrally formed, and the section 111 of the connection part of the detection mandrel 110 and the detection handheld end 120 is concave and is subjected to sanding treatment, so that a better limiting effect is achieved. The inner diameter core rod 100 is made of Cr12Mov, the hardness range is HRC 52-56 degrees, and the inner diameter core rod 100 is formed through vacuum heat treatment.
The outer diameter 110b of the detection core rod 110 is smaller than the inner diameter 200a of the product 200 to be detected, the length 110c of the detection core rod 110 is larger than the length 200b of the product 200 to be detected, and the outer diameter 111a of the joint 111 is smaller than the inner diameter 110a of the detection core rod 110.
The utility model discloses an internal diameter core rod 100 internal diameter size and straightness accuracy examine simultaneously, can effectually avoid the problem that prior art exists, the utility model discloses only examine once just can judge whether internal diameter size and straightness accuracy meet the regulation requirement, greatly shortened check-out time.
The utility model discloses an internal diameter plug 100 is applicable to pipe (external diameter phi 8 to phi 38), square pipe (external diameter 12 phi 12 to 20), rectangular pipe (external diameter 18 phi 12 to 25.4 15.88) etc. and can make suitable internal diameter plug according to the internal diameter size of product and the length of product to thereby can not because the operation is too fast the hourglass scheduling problem that examines that causes.
Because of possessing the above structure, the utility model discloses an operating principle as follows:
when the inner diameter core rod 100 is used, the inner diameter core rod 100 penetrates from one end of the product 200 to be tested to the other end, the inner diameter core rod 100 is ensured to penetrate through the whole product 200 to be tested, and the inner diameter size and the straightness of the product 200 to be tested can be judged to be qualified. And (3) the rest conditions are as follows: if the inner diameter core rod 100 can not penetrate through the whole product 200 to be measured or can not penetrate into the inner hole of the product, the inner diameter size and the straightness of the product are judged to be unqualified.
The product inspection method of the utility model can help the manufacturers using the inner diameter core rod to save time and cost. In the age of this efficiency, it is the maximum profit of this enterprise to practice thrift for the enterprise, so this patent can help the enterprise to improve efficiency, reduces unnecessary inspection process, reduces the waste for the enterprise. And can meet the requirements of customers.
The basic principles and main features of the present invention and the advantages of the product inspection method of the present invention have been shown and described above. It should be understood by those skilled in the art that the product inspection method of the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the product inspection method of the present invention, and the product inspection method of the present invention can have various changes and improvements, which fall within the scope of the product inspection method of the present invention. The scope of the claimed product inspection method is defined by the appended claims and equivalents thereof.
