Abstract
The utility model discloses a kind of clutch housing dilating fixture, comprise die combination and lower die combination, described upper die combination comprises upper plate, pressing plate and pressure head; The alignment pin that described lower die combination comprises lower shoe, is fixed on the expansion block on lower shoe and is arranged in the middle part of expansion block, described expansion block is provided with the taper seat coordinated with outer cover oral area, is provided with top and spring in axially directed hole.Lower die combination is fixed on the workbench of hydraulic press, upper die combination is fixed on the main shaft of hydraulic press, being buckled by underproof for oral area geomery outer cover is placed in expansion block, alignment pin and outer cover inner hole are to locate housing position, during work, pressure head promotes outer cover and overcomes spring thrust and move down, when the oral area of outer cover moves along the taper seat in expansion block, outer cover oral area shape is corrected, and makes finish dimensional reach regulation requirement; After expansion terminates, come directly towards and upwards ejected by outer cover under spring thrust effect, can take out outer cover easily, operating efficiency is high.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of external diameter expansion frock of outer cover of clutch.
Background technology
Clutch of motorcycle comprises the outer cover composition of outputting power and the center composition of input power, and outer cover composition comprises again outer cover, and the part such as gear, damping spring, cover plate of outer cover riveting.
Wherein outer cover is circumferentially provided with some grooves, the latch of clutch friction plate edge is placed in a groove, thus heavily realizes the power transmission between outer cover and friction plate at rotation process.
But difference problem and in outer cover process may be there is during fabrication due to outer cover mouth diameters, also outer cover oral area shape problem on deformation may be there is, this makes when friction plate is assembled into after on outer cover, clamping stagnation problem is there is because the reasons such as outer cover distortion or dimension overproof can cause friction plate to slide up and down in a groove, and friction plate clamping stagnation can cause clutch to occur the problems such as power can not cut off immediately making the functional reliability of clutch reduce in separation process.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of clutch housing dilating fixture, with solve existing clutch housing because of the reasons such as oral area distortion cause friction plate can not be free to slide and then cause in outer cover clutch functional reliability reduce problem.
The utility model clutch housing dilating fixture, comprise die combination and lower die combination, described upper die combination comprises upper plate, pressing plate and pressure head, and described pressure head is vertically fixed on upper plate by pressing plate; The alignment pin that described lower die combination comprises lower shoe, is fixed on the expansion block on lower shoe and is arranged in the middle part of expansion block, described expansion block is provided with the taper seat coordinated with outer cover oral area, the upper surface of described expansion block is also provided with and axially directed hole, is provided with the top be slidably matched with it and promotes the spring of top upward sliding in described axially directed hole.
Further, be also provided with backing plate between described upper plate and pressing plate, the end of described pressure head withstands on backing plate.
The beneficial effects of the utility model:
The utility model clutch housing dilating fixture, lower die combination is fixed on the workbench of hydraulic press, upper die combination is fixed on the main shaft of hydraulic press, being buckled by underproof for oral area geomery outer cover is placed in expansion block, alignment pin and outer cover inner hole are to locate housing position, during expansion, upper die combination moves down with hydraulic press main shaft, and then pressure head promotes outer cover and overcomes spring thrust and move down, when the oral area of outer cover moves along the taper seat in expansion block, outer cover oral area shape is corrected, and makes finish dimensional reach regulation requirement; After expansion terminates, come directly towards and upwards ejected by outer cover under spring thrust effect, can take out outer cover easily, operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of clutch housing dilating fixture.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment clutch housing dilating fixture, comprise die combination and lower die combination, described upper die combination comprises upper plate 1, pressing plate 2 and pressure head 3, and described pressure head is vertically fixed on upper plate by pressing plate; The alignment pin 6 that described lower die combination comprises lower shoe 4, is fixed on the expansion block 5 on lower shoe and is arranged in the middle part of expansion block, described expansion block is provided with the taper seat 61 coordinated with outer cover oral area, the upper surface of described expansion block is also provided with and axially directed hole 7, is provided with the top 8 be slidably matched with it and promotes the spring 9 of top upward sliding in described axially directed hole.
The present embodiment clutch housing dilating fixture, lower die combination is fixed on the workbench of hydraulic press, upper die combination is fixed on the main shaft of hydraulic press, being buckled by underproof for oral area geomery outer cover 10 is placed in expansion block 5, alignment pin and outer cover inner hole are to locate housing position, during expansion, upper die combination moves down with hydraulic press main shaft, and then pressure head promotes outer cover and overcomes spring thrust and move down, when the oral area of outer cover moves along the taper seat in expansion block, outer cover oral area shape is corrected, and makes finish dimensional reach regulation requirement; After expansion terminates, come directly towards and upwards ejected by outer cover under spring thrust effect, there will not be outer cover to be stuck in problem in expansion block, can take out outer cover easily, operating efficiency is high.
As the improvement to the present embodiment; backing plate 11 is also provided with between described upper plate and pressing plate; the end of described pressure head withstands on backing plate; backing plate can protect upper plate can not damage in riveting process; make in Long-Time Service; can change easily after pressure head and backing plate wearing and tearing, be conducive to reducing frock maintenance cost.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
