Example Embodiment

[0020] Example 1: see figure 1 , figure 2 with image 3 , The measuring device for the height from the apex of the spherical seat of the tappet of the automobile fuel injection system to the highest point of the roller includes a measuring stand 30, a positioning reference assembly 31, a measuring rod assembly 32, a standard measuring tool 33 and a clamp to be measured The positioning fixture 14 of the tappet assembly 13. The positioning fixture 14 holding the tappet assembly 13 to be tested is fixedly installed on the table surface of the measuring bench 30; the positioning reference assembly 31 is installed on the table surface of the measuring bench 30 through a lower frame 23 Below, the positioning reference assembly 31 has a positioning cylinder 22 that pushes a lower positioning rod 16 and a measurement reference rod 15 through the transmission mechanism. The lower positioning rod 16 abuts against the apex of the spherical surface of the tested tappet assembly 13 13- 2....

Example Embodiment

[0021] The second embodiment: this embodiment is basically the same as the first embodiment, and the differences are as follows: the positioning cylinder 22 in the positioning reference assembly 31 is vertically fixed to the lower frame 23 through a cylinder mounting seat 24, which is different from the A cylinder connecting seat 21 connected to the piston of the positioning cylinder 22 is connected. Both sides of the cylinder connecting seat 21 are fixed with a pull plate 20 by screws, and a spring seat 18 is tightened. The spring seat 18 is installed on a reference connecting plate 17 , A compression spring 19 is installed between the spring seat 18 and the cylinder connecting seat 21; the lower positioning rod 16 and the measurement reference rod 15 are fixedly mounted on the reference connecting plate 17; the reference connecting plate 17 passes through a slider 26 is in sliding fit with a linear guide 25 fixed on the lower frame 23.

Abstract

The invention designs a device for measuring the height from the vertex of a spherical seat of a tappet body assembly of an automobile fuel injection system to the highest point of a roller. The structure of the device mainly comprises a positioning reference assembly and a measuring bar assembly; a lower positioning bar of the positioning reference assembly rises along with a positioning cylinder; the vertex of the spherical seat of the tappet body assembly is positioned by means of a spring force; the upper end face of a follow-up measuring reference bar is a measuring reference; an incision measuring head of the measuring bar assembly drops along with a lifting cylinder, and is acted on the roller by means of the spring force; and a follow-up digital indicator measuring head drops to contact the measuring reference, and the indicating height is a deviation value relative to a standard measuring tool. The device used in an automatic production line can quickly detect the height between the vertex of the spherical seat of the tappet body assembly and the highest point of the roller, improve the detection efficiency, reduce the influence of human factors in the detection process, and improve the quality of a product.

Description

technical field [0001] The device of the present invention is used in the automatic assembly line of the tappet assembly (13) in the fuel injection system of an automobile, and completes the measurement of the height H from the apex of the tappet spherical seat (13-2) to the highest point of the roller (13-1). . Background technique [0002] For the measurement of the height from the top of the spherical seat to the highest point of the roller after the tappet assembly is assembled, the manual measurement method was originally used. The manual measurement method not only has low production efficiency, but also has large uncertainties, and cannot meet the requirements of automatic detection on the automated assembly line. The measuring device is an automatic device for on-line height measurement using a relative measurement method. Contents of the invention [0003] The object of the present invention is to provide a measuring device for the height from the apex of the sp...
