Technical Field
The utility model relates to the technical field of steering systems, in particular to a tool for measuring the stiffness force value of a middle shaft spring.
Background
The intermediate shaft of the steering machine is a very important safety part of an automobile, and the main effect is that the angle of the steering wheel is transmitted to the steering machine so as to drive the tire to steer, therefore, in the production process, the precision requirement on parts of the intermediate shaft is very high, one part of the intermediate shaft is a spring, the spring is an arc spring, and the spring is formed by stamping and then is subjected to heat treatment, so that the stamping consistency is stable in size, the most critical evaluation of the spring is a spring stiffness force value, and the measurement position and positioning are not quasi-effective on the measurement stiffness force value.
Disclosure of Invention
The utility model provides a tool for measuring the spring stiffness force value of an intermediate shaft to overcome the defects of the prior art, which can ensure that the contact position of a spring and an actual part is basically consistent, and the stress state of the spring can be simulated through the tool, so that the spring stiffness force value can be objectively tested.
A frock for jackshaft spring rigidity value measurement, includes frock benchmark body, its characterized in that: the tool datum body is of a semicircular cylinder structure, the rear end of the tool datum body is connected with a spring hook positioning block, and a spring hook positioning groove is formed in the spring hook positioning block; left and right positioning blocks are respectively arranged on the left and right sides of the upper part of the tool reference body.
The front end face of the tool reference body is provided with a semicircular groove.
The spring hook positioning block is of a semicircular cylinder structure, and the radius of the spring hook positioning block is larger than that of the tool datum body.
The spring hook positioning groove is a rectangular groove, and the bottom of the spring hook positioning groove is flush with the top of the spring hook positioning block.
One side of the left positioning block and one side of the right positioning block are connected with the upper part of the tool datum body, and the left positioning block and the right positioning block are in fan-shaped arrangement.
The inner side end surfaces of the left positioning block and the right positioning block are curved surfaces, and the outer side end surfaces of the left positioning block and the right positioning block are bevel planes.
Compared with the prior art, the tool for measuring the spring stiffness force value of the intermediate shaft can ensure that the contact position of the spring and an actual part is basically consistent, and the spring stress state can be simulated through the tool, so that the spring stiffness force value can be objectively tested.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 2, the tool reference body 1 is of a semicircular cylinder structure, the rear end of the tool reference body 1 is connected with a spring hook positioning block 2, and the spring hook positioning block 2 is provided with a spring hook positioning groove 3; left locating blocks 5 and right locating blocks 6 are respectively arranged on the left side and the right side of the upper portion of the tool datum body 1.
The front end face of the tool datum body 1 is provided with a semicircular groove 4.
The spring hook positioning block 2 is of a semicircular cylinder structure, and the radius of the spring hook positioning block 2 is larger than that of the tool datum body 1.
The spring hook positioning groove 3 is a rectangular groove, and the bottom of the spring hook positioning groove 3 is flush with the top of the spring hook positioning block 2.
One side of the left positioning block 5 and one side of the right positioning block 6 are connected with the upper part of the tool datum body 1, and the left positioning block 5 and the right positioning block 6 are in fan-shaped unfolding arrangement.
The inner side end surfaces of the left positioning block 5 and the right positioning block 6 are curved surfaces, and the outer side end surfaces of the left positioning block 5 and the right positioning block 6 are bevel planes.
As shown in FIG. 1, the spring to be tested has six spring plates, which can be tested independently or synchronously.
As shown in fig. 3 to 5, the tested spring is mounted on the tool of the utility model, and the hooks at the front and rear section ends of the tested spring are respectively clamped in the semicircular groove 4 and the spring hook positioning groove 3 at the front end of the tool reference body 1, and the bottom of the tested spring is attached to the arc surface at the top of the tool reference body 1. The tool is fixed through the V-shaped magnet block, and the V-shaped magnet block is a conventional auxiliary detection tool and has the functions of attaching and sucking the plane of the tool to keep stability; and then the spring plate on the tested spring is tested for force value through the spring stiffness instrument.
Each elastic piece on the measured spring can ensure that each measurement is on the same reference, the consistency of the measured parts is good, and the time is saved.
The tool has a guiding thought for the special-shaped part measuring method, the high-precision measuring requirement can be met through matching of the tool and the part, and the die debugging and detecting time is saved.
