Description
Technical field
The utility model relates to high-pressure fuel pump of diesel engine parts machining apparatus field, is specifically related to a kind of fixture device for injection pump support drill hole.
Background technology
At present, diesel engine for automobile high-pressure pump timing driving system type of drive majority adopts geartransmission or chain gear. On the one hand, traditional geartransmission becomes a kind of main type of drive with advantages such as the transmitting ratio of its stability, higher transmission efficiency, higher reliability and longer work-ing lifes thereof; On the other hand, when the between centers of grit one's teeth oil pump and bent axle is bigger, simultaneously for meeting the requirement of diesel engine to lightweight, lower noise, the development of high rotary speed direction, with the develop rapidly of chain gear technology, chain gear is applied in the formal transmission system of injection pump more and more.
Certainly, the injection pump of diesel engine is as accurate component, unavoidably have the part of many abnormity, such as the chain connecting bracket of injection pump inside, although this support size is less but complex-shaped, prior art alignment carries out adding man-hour, often adopt many traditional fixture actings in conjunction that support is carried out clamping, although support can be clamped, but traditional mode not only operates trouble, and clamping efficiency is not high yet, many times volume production support just can only ensure output by increasing skilled skilled worker, the manpower that this kind of mode of production not only expends are more, and the technical ability of skilled worker is required also higher, traditional mode of production far can not meet the production requirement of modern society.
Practical novel content
The utility model is intended to provide a kind of fixture device for injection pump support drill hole, it is to increase the clamping efficiency of support.
For solving the problem, there is provided following base case: a kind of fixture device for injection pump support drill hole, comprise frame, permanent seat, supporting member, guiding seat, depression bar, wabble wheel, permanent seat is fixedly mounted in frame, the right side of permanent seat has a square step, supporting member has three, wherein two supporting members are fixedly mounted on the right side of fixed support seat, guiding seat is fixedly mounted in frame, guiding seat has the through hole of a transverse direction, depression bar through guiding seat on through hole and with through hole sliding connection, the right side of wabble wheel has a hand handle, wabble wheel is movably articulated in frame, wabble wheel has an annular groove, the right-hand member of depression bar and annular groove are slidably matched and can slide along annular groove.
The lower left side of support is supported and fixes by the square step of permanent seat, and supporting and fixedly mounting supporting member on seat is to coordinate the shape of support so that support can have good impetus on support seat. Cross through hole on guiding seat passes for depression bar, and depression bar and being slidably matched of through hole limit the movable direction of depression bar, make supporting member that the left end of depression bar installs can with the supporting member acting in conjunction of installation on permanent seat, support is clamped.
Chute on the right-hand member of depression bar and wabble wheel is slidably matched, and the both sides of annular groove have one section of asymptotic line similar with cam. Hand handle on pendulum rotating driving wheel, along with wabble wheel rotates in frame, the both sides asymptotic line of annular groove impels depression bar to move forward, and is clamped the both sides of support by supporting member gradually, then completes lower one drilling operating of support. After support drill hole, only need reverse rotation hand just can releases clamp, it is to increase the working (machining) efficiency of support, simple to operation, save the support clamping time, it is to increase the clamping efficiency of support.
Prioritization scheme one: as the further optimization to base case, buffering mechanism also it is provided with between depression bar and guiding seat, buffering mechanism comprises compression spring and gland, the inner left end of the through hole having on guiding seat is formed with ring-shaped step, depression bar is also formed with annular flange flange, annular flange flange and right section of through hole are slidably matched, and are provided with compression spring between the right side of ring-shaped step and the left side of annular flange flange, and compression spring is sleeved on depression bar. The right side of annular flange flange is provided with gland, and depression bar is fixedly connected on the right side of guiding seat through gland, gland by bolt or screw. Support is in the process of boring, sometimes unavoidably because boring resistance is excessive, the sliding position of depression bar and annular groove can be changed, thus loosening because of support, by arranging buffering mechanism, it is supplied to depression bar preliminary tension by compression spring, the clamped position that compression spring ensures support even if support send director also to have once in a while in clamping process, it is possible to make depression bar clamp more firm by supporting member to support, thus effectively ensure that the drilling quality of support.
Prioritization scheme two: as the further optimization to prioritization scheme one, the both sides of annular groove have one section of Locking arc similar with cam. After support is clamped, the Locking arc of chute both sides contacts with the right-hand member of depression bar, even if pendulum rotating driving wheel again, the Locking arc of the right-hand member of depression bar in chute slides, depression bar is appointed so by support clamping together with supporting member, can so just be possible to prevent support when carrying out drilling operating, can not be lived by effective clamping due to, vibration excessive by power suddenly or other reason, support is stabilized on processing stations always, ensure that the processing quality of support drill hole.
Prioritization scheme three: as the further optimization to prioritization scheme two, frame is also provided with hydro-cylinder, and hydro-cylinder is movably hinged and is arranged in frame, and piston rod and the wabble wheel of hydro-cylinder are movably hinged. Drive wabble wheel rotation by hydro-cylinder thus support is clamped, not only reduce the workload of people, and the clamping efficiency making cam have also been obtained higher.
