Abstract
The utility model relates to a screw type hand-operated air door mounting or detaching tool. The utility model mainly solves the problem that an existing female cone is difficult to match with a drilling head, and the salvage efficiency is low. The utility model is characterized in that a seating shoe (1) is provided with an n-shaped support (2); the middle part of the beam (3) of the support (2) is drilled with a rotary screw rod (5) whose lower part is hinged with an x-shaped pressboard (4). The screw type hand-operated air door mounting or detaching tool has a plurality of characteristics that the female cone is quick to match with the drilling head; the simple structure; the efficiency of salvage is high.
Description
Technical field:
The utility model relates to the used spiracle disassembling and assembling instrument of field of internal combustion engine, especially spiral manual valve dismounting facility.
Background technology:
In internal combustion engine reconditioning work process, often need carry out dismounting to valve, and present spiracle disassembling and assembling its originally be manual carrying out, earlier valve spring is depressed during the dismounting valve, take off button watt, spring base, behind the retracting spring, take off valve; When valve was installed, the dress valve spring was enclosed within on the valve earlier, and the mounting spring seat presses down spring, loaded onto button watt, and retracting spring gets final product.In disassembly process, valve spring will be under the compressive state always, spring easily jumps out and hurts sb.'s feelings during operation, so just exist potential safety hazard, large combustion machine valve reaches dozens of simultaneously, and by manual dismounting time and effort consuming, labor strength is big, make the internal combustion engine repair cost increase, reduce dismounting efficient.
The utility model content:
In order to overcome existing low, the inefficient deficiency of dismounting of manual dismounting valve safety coefficient, the utility model provides a kind of spiral manual valve dismounting facility, and these spiral manual valve dismounting facility have handling safety, characteristics that dismounting efficient is high.
The technical solution of the utility model is: these spiral manual valve dismounting facility comprise base, and " door " font support is arranged on the base, are installed with the rotating threaded shaft that the lower end is hinged with " ten " font pressing plate on the crossbeam of support between two parties.
Above-mentioned crossbeam two ends are the hinged and bolting with column respectively, and the rotating threaded shaft upper end has boosting-rod, and pressing plate has through hole respectively for four jiaos, and the base upper surface is connected with locating piece.
The beneficial effect that the utlity model has is: these spiral manual valve dismounting facility are owing to be fixed with support on base, be installed with rotating threaded shaft on the crossbeam of support, the rotating threaded shaft lower end is hinged with pressing plate, like this when the dismounting valve, valve spring can be compressed by rotating rotating threaded shaft, thereby the phenomenon generation that spring easily jumps out and hurts sb.'s feelings when having solved operation, eliminated potential safety hazard, dismounting is time saving and energy saving, reduced labor strength, make the internal combustion engine repair cost increase reduction, improve dismounting efficient, and simple in structure.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is vertical views of Fig. 1.
1-base among the figure, 2-support, 3-crossbeam, 4-pressing plate, 5-rotating threaded shaft, 6-boosting-rod, 7-hole, 8-locating piece.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Figure 2, these spiral manual valve dismounting facility comprise base 1, " door " font support 2 is arranged on the base 1, crossbeam 3 one ends and column on the support 2 are hinged, and the other end is by bolting, when the dismounting valve, earlier bolt is unclamped, crossbeam 3 rotations are opened, cylinder head is lifted on base 1, make cylinder head be convenient to lift from top; Be installed with rotating threaded shaft 5 on the crossbeam 3 between two parties, rotating threaded shaft 5 lower ends are hinged with " ten " font pressing plate 4, pressing plate has through hole 7 respectively for 4 four jiaos, rotating threaded shaft 5 upper ends have boosting-rod 6, can rotate rotating threaded shaft 5 by boosting-rod 6 moves up and down, driving pressing plate 4 moves up and down, make pressing plate 4 compressions or unclamp valve spring, thereby realize the dismounting of valve, potential safety hazard has been eliminated in the phenomenon generation that spring easily jumps out and hurts sb.'s feelings when having solved operation, dismounting is time saving and energy saving, reduce labor strength, made the internal combustion engine repair cost increase reduction, improved dismounting efficient; Base 1 upper surface is connected with locating piece 8, is used to limit cylinder head, and the valve on the cylinder head can be aligned with pressing plate 4.
Claims (5)
1, a kind of spiral manual valve dismounting facility comprise base (1), it is characterized in that: " door " font support (2) is arranged on the base (1), be installed with the rotating threaded shaft (5) that the lower end is hinged with " ten " font pressing plate (4) on the crossbeam (3) of support (2) between two parties.
2, spiral manual valve dismounting facility according to claim 1, it is characterized in that: crossbeam (3) two ends are the hinged and bolting with column respectively.
