Abstract
The utility model relates to a universal type air valve mounting and dismounting tool which comprises a U-shaped arm, adjusting sliding blocks, a jack-prop and a threaded rod. The tool is characterized in that the middle section and the upper and lower ends of the U-shaped arm are connected with the adjusting sliding blocks, the adjusting sliding block at the lower end of the U-shaped arm is fixedly connected with the jack-prop, and the adjusting sliding block at the upper end of the U-shaped arm is connected with the threaded rod. The positive effects are that the tool can not be limited by the shape of a cylinder cover of an engine and the size and the position of an air valve spring plate, solves the air valve mounting and dismounting problem of a new developed engine mode and a foreign model machine, and saves a large amount of time for tests. In addition, the tool is simple in structure, and convenient for mounting and carrying, and saves manpower cost, with only one to two persons needed, so that the tool is simple in structure and easy to know. In a word, the tool can be time-saving and labor-saving, can save a large amount of developing cost, and can be suitable for engine cylinder covers with different shapes by adjusting the sliding blocks at different positions. Connecting pieces of the tool can be universal for all air valves and air valve seats.
Description
Technical field
The utility model relates to a kind of universal valve mounting and dismounting tool, belongs to engine mechanical developing instrument technical field.
Background technology
In the engine development process, the special-purpose mounting and dismounting tool of valve is of a great variety at present, and each of exploitation type all needs special a kind of valve mounting and dismounting tool.Because the difference of multiple factors such as engine valve layout, initial tension of spring, valve spring dish, cause the valve mounting and dismounting tool of various types basically can not be general, so just increased development cost.Particularly when making external model machine and analyze owing to there is not specific purpose tool, the type that has dismounting not valve spring, promptly enabling of having disassembles, and also has no idea to install.Brought very big inconvenience for follow-up test.In order to address the above problem, through long-term improvement, test in a large number and manufacture experimently, develop universal valve mounting and dismounting tool.At exploitation of engine new architecture and external model machine timestamp has all been obtained extensive use.
Summary of the invention
The utility model provides a kind of universal valve mounting and dismounting tool.This universal instrument can adapt to difform engine cylinder cover through regulating the slide block of diverse location; General all valves of its connector and valve seating.
The technical scheme of the utility model is achieved in that universal valve mounting and dismounting tool; By U type arm, adjusting slider, fore-set; Screw rod is formed; It is characterized in that: U type arm stage casing is connected with adjusting slider with two ends up and down, and U type arm lower end adjusting slider is fixedly connected with fore-set, and U type arm upper end adjusting slider is connected with screw rod.
The good effect of the utility model is the restriction that does not receive engine cylinder cover shape and valve spring dish size and position, has solved the valve installing/dismounting problem of engine model newly developed and external model machine, for the plenty of time has been saved in test.In addition, this tool construction is simple, be convenient to install and carry, and saved human cost, only needs 1-2 people, and is simple in structure understandable.In a word, universal valve mounting and dismounting tool can accomplish to save time, laborsaving, and can practice thrift very big development cost.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further: as shown in Figure 1, universal valve mounting and dismounting tool is by U type arm 1; Adjusting slider 2; Fore-set 3, screw rod 4 is formed, and it is characterized in that: U type arm 1 stage casing is connected with adjusting slider 2 with two ends up and down; U type arm 1 lower end adjusting slider is fixedly connected with fore-set 3, and U type arm 1 upper end adjusting slider is connected with screw rod 4.
During use, as shown in Figure 1, valve is placed on the fore-set 3, regulate adjusting slider 2; Make valve 8, fore-set 3, screw rod 4 point-blank, be placed on connector 5 on the valve seating 7, with holding tight U type arm 1, with hand or spanner to screw rod 4 application of forces; Screw rod 4 underspins drive connector 5 and move down, because fore-set 3 withstands valve 8; Valve 8 is motionless all the time, and at this moment valve seating 7 leaves valve 8, till exposing lock dog 6 fully.Install or take out lock dog 6 with the magnetic screwdriver, to screw rod 4 application of force counter-forces, valve seating 7 resets with hand or spanner.
