Abstract
The invention relates to a camshaft straightener, and belongs to the field of machinery. The main characteristic is that two leveled fixed-distance templates can move in a mutual motion to drive the cam shaft between the two templates to roll in opposite directions, and the cam shaft can be straightened in the rolling process. The invention can simplify and batch the alignment of the camshaft, greatly reduce the labor intensity and improve the working efficiency. The invention is also suitable for straightening bars.
Description
Technical field
The invention belongs to the mechanical technique territory, particularly a kind of cam axle straightening machine.
Background technology
Camshaft is an important spare part in the engine air distribution system, be responsible for driving valve opening and closing on time, can regularly suck fresh air when cooperating engine operation, and in time waste gas after burning be discharged, require camshaft should have certain toughness that very high wearability is arranged again.
The camshaft alignment is a requisite important procedure in the camshaft process.The tradition straightener is the centre bore location with the camshaft both ends of the surface, and is middle with the V-block support, in the outer radius of different bearing guards or axle journal one dial gauge is installed.Press with pressure head at bearing guard or axle journal peak place with hand rotating cam moving axis, the rotating cam axle is located axial runout in the technological requirement scope until this again.Change a place then, finish until whole camshaft alignment.Whole alignment process at least will the school be surveyed three times, operates complicatedly, and labour intensity is big, inefficiency.
Summary of the invention
Purpose of the present invention puts forward at the present situation of present camshaft alignment, and to be camshaft rolled between the spacing template of alignment at two principal character, thereby reaches the requirement of camshaft alignment.Concrete technical scheme is as follows:
1, the portal frame base is established rail plate, is slide unit on the guide rail, and alignment template down is installed on the slide unit.
2, set firmly the alignment template under the portal frame crossbeam, the described alignment template inlet of going up has constant slope.
3, described slide unit provides the slip required drive by hydraulic jack.
When cam axle straightening machine involved in the present invention was worked, camshaft was put the straightener porch, and the alignment template was slided to the oil cylinder direction under hydraulic jack work traction slide unit drove, the relative motion of upper and lower alignment template, and the drive camshaft rolls.Because the bolster spacing is constant, in the camshaft rolling process promptly by alignment.
As improvement of the present invention, the required power of described slide unit slip can be motor, by gear and tooth bar transmission.Described cope match-plate pattern links by at least one hydraulic cylinder and portal frame, uses to be fit to the alignment of different-diameter camshaft.
The present invention can make camshaft alignment simplification, mass, reduces labor intensity greatly, increases work efficiency.

Fig. 2 is that length center line plane of the present invention is looked schematic diagram
Among the figure: 1-base, 2-guide rail, 3-slide unit, 4-lower bolster, 5-camshaft, 6-cope match-plate pattern curved surface, 7-cope match-plate pattern, 8-portal frame, 9-hydraulic jack
The specific embodiment
The present invention relates to a kind of cam axle straightening machine, mainly comprise base 1, guide rail 2, slide unit 3, lower bolster 4, cope match-plate pattern 7, portal frame 8 and hydraulic jack 9.The described upper and lower plate of touching is installed in respectively on portal frame crossbeam and the slide unit, and cope match-plate pattern curved surface 6 is positioned at camshaft 5 porch.Described slide unit places on two guide rails that are installed on the base, and slide unit provides mobile required drive by the hydraulic jack that is installed on the base one end center line.
When the present invention worked, camshaft 5 deposited 6 on template 4 and cope match-plate pattern curved surface, and hydraulic jack 9 work drive slide unit 3 and lower bolster 4 slides, and the relative motion of upper and lower alignment template drives camshaft 5 and rolls round about between upper and lower template.Because the bolster spacing is constant, promptly obtains alignment in camshaft 5 rolling processes.
As improvement of the present invention, the required power of described slide unit slip can be motor, and by gear and tooth bar transmission.Described cope match-plate pattern links by at least one hydraulic cylinder and portal frame, uses to be fit to the alignment of different-diameter camshaft.
Claims (5)
1, the present invention relates to a kind of cam axle straightening machine, belong to mechanical field.Principal character is that two set a distance templates of having smoothed can be moved mutually and move, and drives to place two camshafts between template to roll round about, and rolling process convexity wheel shaft is able to alignment.
2, according to claim 1, two templates can take wherein one to move, and also can take two whiles to move round about.Embodiment takes cope match-plate pattern motionless, and lower bolster slides.
3, according to claim 1, the present invention can be provided with and regulate bolster spacing device or system, to adapt to the alignment of different-diameter camshaft.
4, according to claim 1,2, template moves used power can be hydraulic drive (present embodiment employing hydraulic cylinder), also can be with other power modes such as motor.
5, according to claim 1, the present invention can be used for the bar alignment.
