Description
Technical Field
The utility model relates to a drilling frock, concretely relates to special frock of wheel oil filler point processing.
Background
The wheel filler point is a deep hole in the wheel camber, and is typically used as a lubrication filler point. Because the central line and the axial direction of the wheel form an included angle of 45 degrees, the wheel is difficult to process by adopting a common drilling machine. For example mine is with 2.4m dustpan wheel, 3m dustpan wheel and 10T balanced wheel, their appearance is approximate, and drilling process, technology are the same, owing to relate to 45 inclined hole processing, and the marking off, location accuracy are difficult to guarantee, often because location accuracy causes positional deviation inadequately during drilling, and then the condition such as lead to the drill bit rupture takes place, seriously influences drilling safety and product quality. On the other hand, by adopting the existing common drilling machine, over 80% of products after the oil filling hole is processed need to be added with a process of manually chiseling an oil groove, so that not only is the labor intensity increased, but also the production efficiency is severely restricted.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a wheel oil filler point processing frock is provided, can conveniently carry out 45 jiaos of drilling processing of wheel to alleviate intensity of labour, provide finished product quality and work efficiency.
The technical scheme of the utility model as follows:
The wheel oil filling hole machining tool comprises a workbench and a clamp base fixedly arranged on the workbench, wherein a support body is fixedly arranged on the clamp base; the upper end of the supporting body is provided with an upper cover plate, the upper cover plate is provided with a sliding chute which runs in the left-right direction, and the upper cover plate is fixed on the supporting body through a positioning bolt which penetrates through the sliding chute and extends into an inner screw hole of the supporting body; the upper cover plate is also provided with a longitudinal through hole, and a drill bushing of which the center line forms an included angle of 90 degrees with the upper surface of the workbench is arranged in the longitudinal through hole; the tool further comprises a center bolt for penetrating through the center hole of the wheel, the lower end of the center bolt is connected with a fixing screw hole, and the fixing screw hole is formed in the right side portion of the support body and located below the inclined plane of the support body, or formed in the right side portion of the support body on the clamp base, or formed in the joint portion of the support body and the clamp base.
Preferably, the tool further comprises a limiting groove formed in the workbench, and the limiting groove is upward in opening and located on the lower right of the inclined plane of the base.
The utility model has the advantages of:
One, the utility model discloses a bolt is fixed in the drilling machine workstation with the wheel on to through 45 backup pad location wheels, utilize lock nut locking wheel. The upper cover plate can be horizontally used along the upper end surface of the support body to adjust the relative positions of the drill bit and the wheel, and is positioned by fastening the positioning bolt after sliding in place. Has the characteristics of good rigidity and convenient accurate positioning. The quality of finished products and the drilling efficiency are greatly improved. The clamping device has the advantages of reliable clamping, safety and high efficiency, the one-time qualification rate of the product is 100% after trial, and the processing efficiency is improved by about 40%.
And secondly, the workbench is provided with a limiting groove for supporting the wheel from the lower end, and the partial stress of the wheel is dispersed to the workbench through the lower end during machining, so that the wheel is ensured to be more stable, the stress of the workbench is more balanced, and the stress deformation of the central bolt is effectively reduced.
Drawings
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, the embodiment of the present invention includes a workbench 1 and a fixture base 2 fixedly installed on the workbench 1, and a support body 3 is fixedly installed on the fixture base 2. The right end of the clamp base 2 is provided with a base inclined plane 11 which forms an included angle of 45 degrees with the upper surface of the workbench 1, and the right side part of the support body 3 is provided with a support body inclined plane 13 which forms an included angle of 45 degrees with the upper surface of the workbench 1. The base inclined plane 11 and the support inclined plane 13 are in the same plane.
an upper cover plate 4 is installed at the upper end of the supporting body 3, a sliding groove 5 with a left-right trend is formed in the upper cover plate 4, and the upper cover plate 4 is fixed on the supporting body 3 through a positioning bolt 6 which penetrates through the sliding groove 5 and extends into a threaded hole in the supporting body 3. The nut at the upper end of the positioning bolt 6 is loosened, the upper cover plate 4 can move left and right, and the nut is fastened after the upper cover plate moves in place. The right end of the upper cover plate 4 is provided with a longitudinal through hole, and a drill bushing 7 with a central line forming an included angle of 90 degrees with the upper surface of the workbench 1 is arranged in the longitudinal through hole.
