Background
The tripod universal joint is mainly used for inner ball cage of four-wheel driven vehicle and consists of outer sleeve, tripod, ball ring and rolling needle. As shown in figure 1, the distance (dimension L in figure 2) from the specified position (the position of dimension phi A in figure 2) of the inner hole opening part to the end face of the tripod is not detected by the universal gauge due to special structure, and the distance needs to be converted after being detected by a precision profilometer.
The prior art scheme has the following defects: (1) the detection mode is indirect measurement, and the operation is complex; (2) in the production and processing process, a contourgraph first piece is required to be used for measuring the distance size from a specified position of an inner orifice part to an end face during processing every day, and the size is required to be rechecked after a blade is replaced or a tool is adjusted; (3) the contourgraph is a precision measurement device, needs professional personnel to operate, can not be operated by general field operators, can only be carried out by means of submission, has long detection time and low detection efficiency, and is not beneficial to production field control.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the background, solve the problems that the distance dimension from the specified position of the orifice part in the tripod to the end surface is inconvenient to detect, the detection time is long, and the field production control is not facilitated, and provide a solution for the distance dimension detection tool from the specified position of the orifice part to the end surface, which is beneficial to the field control of batch production, realizes direct measurement, and has convenient, accurate and efficient detection.
The technical scheme adopted by the utility model is as follows:
a checking fixture for measuring the distance from a specified position of an opening part of a tripod to an end face comprises a base, a step and a mold core, wherein the step is cylindrical and is vertically fixed on the top surface of the base, and the outer diameter of the step is the same as the standard diameter of the specified position of the opening part of the tripod; the mold core is cylindric, vertically fixes at the top surface of step, and the external diameter of mold core and the bore internal diameter clearance fit of three round pin framves, and the axial height of mold core equals the standard distance of three round pin frame oral area assigned position to the terminal surface.
Preferably, the outer diameter of the mold core is smaller than the inner diameter of an inner hole of the tripod head by 0.05-0.20 mm.
The utility model has the beneficial effects that: this technical scheme has solved the problem that current precision measurement is unfavorable for production site process control to the realization becomes direct measurement by indirect measurement, detects the contourgraph that to change complicacy and inefficiency into audio-visual detection of beating the table, and is efficient and more convenient. The worker can detect and confirm the actual value of the size and whether the actual value is qualified or not on the site at any time on the station of the worker, the operation is convenient and fast, the detection efficiency is greatly improved, and the quality of the product processing process can be effectively controlled.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, but the present invention is not limited to the following examples, so that the objects, solutions and advantages of the present invention can be more clearly understood by those skilled in the art.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified and limited, specific meanings of the general terms in the present invention may be specifically understood by those skilled in the art.
As shown in fig. 1 to 4, the gauge for measuring the distance from the specified position of the mouth of the tripod rest to the end surface provided by the utility model comprises a base 3, a step 4 and a mold core 5.
The step 4 is cylindrical and vertically fixed on the top surface of the base 3, and the outer diameter (the dimension phi A1 in figures 3 and 4) of the step is the same as the standard diameter (the dimension phi A in figure 2) of the specified position of the opening of the tripod 1. The edge of the top surface of the step 4 is a right-angle edge, so that the step can be ensured to be completely contacted with the designated position of the opening part of the tripod during detection.
The mold core 5 is cylindrical and vertically fixed on the top surface of the step 4, the outer diameter (the size phi C in figure 3) of the mold core 5 is in clearance fit with the inner diameter (the size phi B in figures 2 and 4) of the inner hole 2 of the tripod 1, generally, the outer diameter of the mold core 5 is 0.05-0.20 mm smaller than the inner diameter of the inner hole 2 of the tripod 1, and the mold core can be inserted into the inner hole 2 of the tripod. The axial height of the mold core 5 (dimension L1 in fig. 3) is equal to the standard distance from the specified position of the mouth of the tripod 1 to the end face.
The detection mode of the utility model is as follows:
as shown in fig. 4, a mold core 5 of the checking tool is inserted into an inner hole 2 of the tripod 1, the mouth of the tripod 1 faces downwards and contacts with the edge of the step 4, and thus the designated position of the mouth is determined. A height gauge making method is adopted, the gauge 6 is installed on the clamping frame, the gauge is moved to enable pointers of the gauge 6 (generally a dial indicator) to be in contact with the end face of the three-pin frame 1 and the top face of the mold core 5 respectively, and changes of the pointers of the gauge are observed. For example, if the pointer of the equivalent gauge 6 is displayed as 0 on the top surface of the core 5 (left gauge in fig. 4) and the pointer of the gauge 6 is displayed as +0.05mm on the end surface of the tripod 1 (right gauge in fig. 4), the dimension L of the distance from the specified position of the mouth portion of the tripod to the end surface is 0.05mm larger than the dimension L1 of the axial height of the core, and the actual dimension L of the distance from the specified diameter of the mouth portion of the tripod to the end surface can be easily obtained.
The above description is only a preferred embodiment of the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
