Abstract
The utility model discloses a gear spherical surface rolling depression head. A bracket is Y-shaped, and two rolling wheels are symmetrically installed on a spindle which is fixed on the front fork portion of the bracket. Circular arc segments in the axial section of the spindle are positioned in a same circumference, and the end surfaces of the rolling wheels are provided with plane bearings. An inner hole is provided with a rolling bearing, and the inner portion of the spindle is provided with an oil feed hole. The end surface of the spindle is provided with an oil nozzle, and the stalk portion of the bracket is provided with a sheath. A butterfly spring is arranged between the sheath and the front fork of the bracket. The gear spherical surface rolling depression head is used for rolling, squeezing and processing spherical surface, in particular to the gear spherical surface of the automobile differential mechanism. Since the two rolling wheels roll symmetrically, work pieces are pressed equably. The gear spherical surface rolling depression head has simple installation. The gear spherical surface rolling depression head can improve production efficiency and ensure the product quality. Meanwhile, since the spring has buffer function, the gear spherical surface rolling depression head avoids the rolling wheels butting the work pieces. Additionally, the gear spherical surface rolling depression head is provided with the bearings and the oil hole to cause the gear spherical surface rolling depression head to be flexible, safe, reliable and long in service life.
Description
Technical field
The utility model relates to a kind of sphere machining tool, presses the milled head of processing especially for automobile differential gear sphere edging.
Background technology
The automobile differential gear is used for realizing differential motion when vehicle travels turning, and is most important to traffic safety.The centre of this gear is the hole, and an end is a sphere.Traditional sphere processing method is the Vehicle Processing made allowance, behind heat-treatment quenching, and grinding again, this method production efficiency is low, the cost height, surface roughness and wear resistence are difficult to reach requirement.Advanced processing method is to press processing with carrying out edging with rolling tools behind the sphere finish turning, and existing rolling tools are made of support and a roller usually, and the outer rim of roller is an arc surface, add man-hour, workpiece rotation, roller traverse feed, with the workpiece rotation, carry out edging and press.Because the lateral compression of single roller, the workpiece discontinuity equalization requires height to clamping, and quality be cannot say for sure to demonstrate,prove, and efficient is not high yet; Roller does not have buffer gear simultaneously, and feeding sometimes is careless, answers back to, and causes the damage of workpiece, instrument easily, even has an accident.
The utility model content
The technical problems to be solved in the utility model is to overcome the weak point that existing gear sphere edging is pressed machining tool, provide a kind of and can guarantee crudy, enhance productivity, and avoid answering back to, safe and reliable The gear inner hole squeezer clamp.
The technical solution of the utility model is: The gear inner hole squeezer clamp, comprise roller, support, improvements are that support is " Y " shape, roller has two, two rollers are installed on the mandrel that is fixed in the support front fork part symmetrically, arc section in the two roller axial sections is positioned on the same circumference, and the roller end face is provided with plane bearing.
Further scheme is: the roller endoporus is provided with rolling bearing; Have in the mandrel axially and tank filler sleeve radially, an end of mandrel has the oil nozzle that is connected with tank filler sleeve; The shank of support is provided with the slidingtype sheath, between the front fork of sheath and support butterfly spring is arranged.
Adopt above technical scheme, because roller has two, arc surface is symmetrical, and the no axial float in back is installed, and jointly the gear sphere is carried out edging and presses, and not only raises the efficiency, and also makes the workpiece stress equalization, eliminates the moment of flexure influence, and clamping becomes simply, and quality can guarantee.Owing to the cushioning effect of spring, just in case feeding is too quickly, support can slide in sheath backward, avoids answering back to simultaneously, and the setting of bearing and oilhole in addition guarantees the flexible, reliable, safe, long-acting of this device.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, front fork part at " Y " shape support 1 is being fixed mandrel 2, one pair roller 4 is housed on the mandrel, arc section 5 in the roller axial section is positioned on the same circumference, the roller end face is provided with three plane bearings 3, the roller endoporus is provided with needle bearing 9, by the pad on the adjustment mandrel or the thickness of plane bearing base plate, makes roller not have axial float during installation.There are axial oilhole 7 and radial direction oil hole 6 in mandrel inside, and mandrel one end has oil nozzle 8.The shank of support has sheath 12, and both are sliding to join, and the straight pin 11 that is contained in shank can slide in the groove of sheath, between sheath and the support front fork butterfly spring 10 is arranged.
Claims (4)
1, a kind of The gear inner hole squeezer clamp comprises roller, support, it is characterized in that support is " Y " shape, roller has two, two rollers are installed on the mandrel that is fixed in the support front fork part symmetrically, and the arc section in the two roller axial sections is positioned on the same circumference, and the roller end face is provided with plane bearing.
2, by the described The gear inner hole squeezer clamp of claim 1, it is characterized in that the roller endoporus is provided with rolling bearing.
3, by the described The gear inner hole squeezer clamp of claim 1, it is characterized in that having in the mandrel axially and tank filler sleeve radially, an end of mandrel has the oil nozzle that is connected with tank filler sleeve.
