Abstract
The invention relates to a dedicated clamp for the oil pump of an engine. The dedicated clamp comprises a base, wherein a front bracket and a rear bracket are fixed on the base; a positioning column matched with the rear part of the oil pump is arranged on the rear bracket; a support is fixed on the front bracket; a rotating shaft penetrates the support; a cam is arranged on the rotating shaft; a positioning pin is movably arranged in the support; a pressing block is arranged at the rear end of the positioning pin, and is jointed with the cam; a spring is sleeved on the positioning pin; and the two ends of the spring are propped against the pressing block and the support respectively. The dedicated clamp is suitable for reliable fixation of the oil pump of the engine of a motorcycle.
Description
Technical field
The present invention relates to a kind of special fixture of engine oil pump of motorcycle.
Background technology
The structure of the engine oil pump of motorcycle is big, the anterior less type shape in rear portion usually; When it is cleaned; Usually it is fixing to adopt its front and rear portions of clamp to realize; But because its front portion is less, thus common anchor clamps be difficult to realize reliable fixation, thereby cause engine oil pump in cleaning process, to come off and impaired.
Summary of the invention
Technical problem to be solved by this invention is: a kind of special fixture that can realize secure fixation to engine oil pump is provided.
For addressing the above problem, the technical scheme that the present invention adopts is: the special fixture of engine oil pump comprises base; Be fixed with fore-stock and after-poppet on the base, after-poppet is provided with the reference column that matches with the engine oil pump rear portion, is fixed with bearing on the said fore-stock; Be equipped with rotating shaft in the bearing, rotating shaft is provided with cam, is movably set with alignment pin in the bearing; The rear end of alignment pin is provided with briquetting; Briquetting and cam fit, and the outer cover of alignment pin is provided with spring, and the two ends of spring are inconsistent with briquetting and bearing respectively.
Be provided with the cam stop surface in the said fore-stock, when the wheel limit of cam and this cam stop surface were inconsistent, the far point of cam was positioned at the below of alignment pin central axis.
Said rotating shaft is provided with handle.
The invention has the beneficial effects as follows: the special fixture of above-mentioned engine oil pump, it is simple in structure, easy to use.It is through the rotation of cam, thereby can realize the anterior secure fixation of engine oil pump, can prevent effectively that engine oil pump from coming off and impaired in cleaning process.

Among the figure: 1, base, 2, fore-stock, 3, after-poppet, 4, reference column, 5, bearing, 6, rotating shaft, 7, cam, 8, alignment pin, 9, briquetting, 10, spring, 11, the cam stop surface, 12, the far point of cam, 13, the alignment pin central axis, 14, handle.
The specific embodiment
Through specific embodiment the special fixture of engine oil pump of the present invention is done further to describe in detail below.
Like Fig. 1, shown in Figure 2, the special fixture of engine oil pump comprises base 1; Be fixed with fore-stock 2 and after-poppet 3 on the base 1, after-poppet 3 is provided with the reference column 4 that matches with the engine oil pump rear portion, is fixed with bearing 5 on the said fore-stock 2; Be equipped with rotating shaft 6 in the bearing 5, rotating shaft 6 is provided with cam 7, is movably set with alignment pin 8 in the bearing 5; The rear end of alignment pin 8 is provided with briquetting 9; Briquetting 9 fits with cam 7, and the outer cover of alignment pin 8 is provided with spring 10, and the two ends of spring 10 are inconsistent with briquetting 9 and bearing 5 respectively.
As preferred version, be provided with cam stop surface 11 in the said fore-stock 2, when the wheel limit of cam 7 and this cam stop surface 11 were inconsistent, the far point 12 of cam was positioned at the below of alignment pin central axis 13.
Said rotating shaft 6 is provided with handle 14.
Operation principle of the present invention is: as shown in Figure 3 during use, through the reference column on the after-poppet 34 rear portion of engine oil pump is fixed; Then turning handle 14 makes rotating shaft 6 and cam 7 rotate, and this moment is along with the rotation of cam 7; The far point 12 of cam turns to briquetting 9 and fits, thereby alignment pin 8 is released, and through alignment pin 8 front portion of engine oil pump is fixed; When cam 7 turns to position shown in Figure 4, stop, this moment, the wheel limit and the cam stop surface 11 of cam 7 were inconsistent, thereby restriction cam 7 further turns clockwise; Because the far point 12 of cam is positioned at the below of alignment pin central axis 13 at this moment, under the effect of spring 10 elastic force, briquetting 9 is pushed down cam 7; Limit cam 7 and be rotated counterclockwise, thereby can realize the rotation of cam 7, and then realized the secure fixation of engine oil pump.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
