Detailed Description
The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.
As shown in fig. 1 to 3, the present invention provides a cylinder head valve spring mounting tool for a gas engine, which includes a positioning sleeve 1, and a thrust member 2 and a pressing sleeve 3 provided on the positioning sleeve 1. The positioning kit 1 comprises a positioning screw 10, and the positioning kit 1 is used for fixedly mounting the tool on a specific part of a gas engine shell integrally, preferably on an insert 5 (see fig. 4 and 5) of a cylinder cover 4 which is located at a central position where a plurality of springs are to be mounted. The pressing kit 3 comprises a sleeve 30 and a pressing plate 31, the sleeve 30 is rotatably sleeved on the positioning screw 10 in a vertically movable manner, one end of the pressing plate 31 is connected with the sleeve 30, and the other end of the pressing plate 31 extends outwards and then bends downwards. The pressing member 3 is mainly used for pressing the spring down to a specified position. The pushing element 2 is arranged above the sleeve 30, sleeved on the positioning screw rod 10 and in threaded fit with the positioning screw rod 10, and the sleeve 30 is forced to generate displacement change on the positioning screw rod 10 by rotating the pushing element 2, so that the pressing plate 31 presses the spring down or disengages from the spring.
The positioning kit 1 further comprises a fixing seat 11 connected with the lower end of the positioning screw 10. The fixing seat 11 is integrally of a cylindrical structure with a downward opening, internal threads are arranged on the inner wall of the fixing seat, and the positioning sleeve 1 is integrally positioned and fixed through threaded connection of the internal threads and the insertion sleeve of the cylinder cover. The lower end of the positioning screw rod 10 is connected with the top of the fixed seat 11.
The lower end of the pressing plate 31 is provided with an annular pressing ring 32, and when the pressing plate is used, the pressing ring 32 is in contact fit with the top of the spring to press the spring downwards. The size and dimensions of the pressure ring 32 can be specifically selected and designed according to the type of the spring.
The limiting part 33 protruding downwards is arranged on the outer edge of the pressing ring 32 along the circumferential direction, and a space for accommodating the top of the spring is formed by the limiting part 33 and the bottom surface of the pressing ring 32, so that the stability of pressing is guaranteed. For further facilitating better installation, a position yielding opening is arranged in the middle of the lower end of the pressing plate 31 corresponding to the opening of the pressing ring 32.
