Embodiment Construction
[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.
[0020] Taking the distance from the measuring tube nozzle 12 to the axis of the cylinder body 11 as an example, the present invention has designed a set of measuring devices, such as Figure 2 ~ Figure 4 , the device consists of a measuring disc 1, a support body 2, a positioning block 3, a positioning bolt 4, and a measuring pin shaft 5 components. There are 7 size measuring holes and positioning holes on the end surface of the measuring disc 1 parallel to its axial direction; the supporting body 2 includes a base, and two positioning pins are arranged on the upper end surface of the base, and the supporting body 2 is connected with the measuring disc 1 through the positioning pins. Connected, the lower end surface of the base has a hole with an inner diameter equal to the ou...

The invention discloses a measuring device and method for the spatial dimensions of a hydraulic actuating cylinder. The measuring device comprises a measuring disc (1), a supporting body (2), positioning blocks (3) and a measuring pin (5). Multiple dimension measuring holes and positioning holes are arranged parallel to the axis direction in the end face of the measuring disc (1). The supporting body (2) comprises a base, and a positioning pin is arranged on the upper end face of the base. The supporting body (2) is connected with the measuring disc (1) through the positioning pin. A hole withthe inner diameter equal to the outer diameter of the upper end of an actuating cylinder body (11) is arranged in the lower end face of the base. The device comprises two positioning blocks (3), andeach positioning block (3) is provided with a positioning plane. The upper ends of the two positioning blocks (3) are connected with the lower end of the supporting body (2), and the two positioning planes are parallel to each other. The measuring pin (5) is a cylinder movably connected with the dimension measuring holes and a pipe nozzle (12). By using the measuring device and method of the invention, the labor intensity of workers is reduced, and the production efficiency of parts is improved.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a measuring device and method for the space dimension of a hydraulic cylinder. Background technique [0002] Hydraulic actuator (see sketch for parts figure 1 and Figure 1a ) is made up of cylinder 11, pipe joint 12 and ring 13. The angles between two pipe joints 12 and the positioning datum on cylinder 11 are 10° and 30°, and the four parts are made of manual argon Arc welding is done. After welding, check the space dimensions L±0.3 and (L+3)±0.3 from the center of the two pipe joints to the center of the cylinder, and the measurement error is 0.05. At present, the method of checking the size is to measure the size of each part by three-coordinate measurement. Using this method, the labor intensity of workers is high and the production efficiency is low. Contents of the invention [0003] The present invention aims to provide a measuring device and method ...
