Description
Technical field
The utility model relates to machining equipment field, is specifically related to a kind of gear rolling machine.
Background technology
Along with the develop rapidly of industry, all trades and professions all achieve semi-mechanization or even full mechanical automation, and spline uses widely in plant equipment, nearly all machinery, mechanism all will use, it is all to be distributed processing by some simple lathes that traditional spline is produced, processed complex, labor strength is large, and efficiency is very low.
Gear rolling machine is the special purpose machine tool of the various gear of processing, spline, and its application changes the complexity of conventional method machine tool processing.The spline tooth broaching board that tradition gear rolling machine is arranged, its flank of tooth is type of facing directly the flank of tooth that each teeth portion is identical, but along with the develop rapidly of industry, constantly requiring the operating efficiency improving the machining equipments such as gear rolling machine while, more and more higher to the machining accuracy of product, existing gear rolling machine is difficult to be issued to required precision in the condition of high speed.
Utility model content
The purpose of this utility model be for solve above-mentioned in technical problem, provide a kind of while guarantee process velocity, the gear rolling machine of machining accuracy when can also improve gear rolling machine machining gears, spline greatly
For achieving the above object, the technical solution adopted in the utility model is:
A kind of gear rolling machine, comprise fuselage, servomotor, gear rolling mechanism, described driven by servomotor gear rolling mechanism action, described gear rolling mechanism is fixedly installed on fuselage, described gear rolling mechanism comprises slide unit and lower slide unit, and the two is connected to spline tooth broaching board and lower spline tooth broaching board respectively, it is characterized in that: described upper spline tooth broaching board is the spline tooth broaching board that the flank of tooth is identical with lower spline tooth broaching board, the flank of tooth of upper spline tooth broaching board from bottom to up and the flank of tooth of lower spline tooth broaching board from top to bottom by preparation tooth, molding gear and exit tooth composition, the profile of tooth of the flank of tooth in these three sections of regions is all identical with the size of tooth; Meanwhile, the flank of tooth in described molding gear region is the flat flank of tooth, and described preparation tooth region is recurvate cambered surface with the flank of tooth exiting tooth region, and namely the equal stage casing of the flank of tooth of upper and lower spline tooth broaching board (4) is smooth, and upper/lower terminal is recurvate cambered surface.
Described preparation tooth, molding gear and exit tooth respectively residing for the length in three sections of regions than being 1:3:1.
The precision of the teeth portion in described molding gear region, higher than the teeth portion precision in preparation tooth region, makes gear rolling machine add the effect reaching " roughing-fine finishining " man-hour to light material.
The technique effect of the utility model gear rolling machine is:
1, compare the flank of tooth of traditional spline tooth broaching board, the preparation tooth that the spline tooth broaching board two ends of the utility model gear rolling machine increase and exit tooth region, machining accuracy and working (machining) efficiency can be improved, also can reduce after machining and again reconditioning process is carried out to the gear processed or spline;
2, spline tooth broaching board preparing the setting of tooth, first can carry out roughing to light material, avoiding light material because being damaged the interior tissue of light material by directly carrying out the higher fine finishining of intensity, increase shaping after gear or service life of spline.
Accompanying drawing explanation
Fig. 1 is the structural representation of the gear rolling mechanism of the utility model gear rolling machine.
Illustrate: 1, upper slide unit 2, lower slide unit 3, upper spline tooth broaching board 4, lower spline tooth broaching board 5, preparation tooth 6, molding gear 7, exit tooth 8, light material.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Gear rolling machine comprises fuselage, servomotor, gear rolling mechanism, and wherein, described driven by servomotor gear rolling mechanism action, gear rolling mechanism is fixedly installed on fuselage.
As shown in Figure 1, gear rolling mechanism comprises slide unit (1) and lower slide unit (2), and upper slide unit (1) and lower slide unit (2) surface are connected to spline tooth broaching board (3) and lower spline tooth broaching board (4) respectively, on this, spline tooth broaching board (3) is identical with the flank of tooth of lower spline tooth broaching board (4), the flank of tooth is relative, operationally do the middle part line position between tooth plate face that light material (8) that move toward one another need process then needs to deliver to upper spline tooth broaching board (3) and lower spline tooth broaching board (4) by feed mechanism, namely the distance of light material (8) the distance two ends flank of tooth is all identical.
In gear rolling machine of the present utility model, upper spline tooth broaching board (3) is identical with the flank of tooth of lower spline tooth broaching board (4), the flank of tooth of upper spline tooth broaching board (3) from the bottom to top and the flank of tooth of lower spline tooth broaching board (4) be divided into three sections of regions from top to bottom, namely tooth (5) is prepared, molding gear (6) and exit tooth (7), wherein prepare tooth (5) region and be trickle bending cambered surface backward with the flank of tooth exiting tooth (7) region, make, the flank of tooth of lower spline tooth broaching board (4) is all smooth in stage casing as shown in Figure 1, on, lower two ends are recurvate cambered surface, and preparation tooth (5), molding gear (6) and exit the spline tooth broaching board flank region shared by tooth (7) three length than being 1:3:1, the precision of the teeth portion in molding gear (6) region is higher than the teeth portion precision of preparing tooth (5) region, .
When gear rolling machine carries out processing work, light material (8) uniform rotation, open servomotor, spline tooth broaching board (3) and lower spline tooth broaching board (4) is made to do direction at the uniform velocity moving in opposite directions, the preparation tooth (5) of the two flank of tooth touches the left and right sides of light material (8) all simultaneously and carries out roughing to light material (8), due to prepare the flank of tooth in tooth (5) region be interior curved differential of the arc face and machining accuracy lower than the machining accuracy of molding gear (6), the processing intensity of preparation tooth (5) is made to be less than the processing intensity of molding gear (6), make the internal organizational structure of light material (8) can adapt to gradually in advance process intensity, namely avoid direct high-strength fine and process the destruction may caused light material (8) internal organization, also owing to carrying out roughing in preparation tooth (5) region, light material (8) is made to accelerate speed when fine finishining is carried out in molding gear (6) region, after molding gear (6) region completes fine finishining, upper spline tooth broaching board (3) and lower gear rolling exit, now owing to exiting the design of tooth (7), can avoid occurring, the afterbody accident collision of lower spline tooth broaching board (4) is in type gear or spline, unnecessary damage is brought to gear or spline.
The above only have expressed preferred embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion, improvement and substitute, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
