Abstract
The utility model discloses a pneumatic drilling machine. The pneumatic drilling machine comprises a pedestal and a drilling bit, wherein a rack is mounted at the upper end of the pedestal in a slide manner; a pressing wheel is mounted on the rack in a rotary manner; the drilling bit is fixed at the lower end of the rack; a motor is connected with the drilling bit in a transmission manner; a cylinder is fixed at the lower end of the pedestal; a wire rope is fixed on the piston rod of the cylinder; the other end of the wire rope is connected with the pressing wheel through a reset spring; an air pipe is connected with the cylinder; and a switch is arranged for controlling the air intake of the air pipe. The pneumatic drilling machine has the advantages of simple structure, low manufacture cost, reliable performance, practical use and high safety, and can reduce the labor intensity.
Description
Technical field
The utility model relates to the equipment of boring, mainly is a kind of pneumatic drilling machine.
Background technology
At present, such work of holing all is to adopt hand processing mostly, but so not only labour intensity is big, wastes time and energy, and production cost is also higher, and drilling depth is manually wayward, makes the yield rate of product of production low.In addition, manually hole knockout easily causes operating personnel injured.
The utility model content
Technical problem to be solved in the utility model provides a kind of pneumatic drilling machine, with pneumatic replacement hand processing, reduces labor intensity, and reduces production cost, improves the yield rate of finished product.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of pneumatic drilling machine includes support, drill bit, and the support upper end is slidingly fitted with tooth bar, is rotatablely equipped with pinch roller on the tooth bar, and the lower end of tooth bar is fixed with drill bit, and drill bit is connected with motor; The lower end of described support is fixed with cylinder, is fixed with steel wire rope on the piston rod of cylinder, and the other end of steel wire rope is connected on the pinch roller by back-moving spring, is connected with tracheae on the described cylinder, and the air inlet of tracheae is controlled by contactor.
The below of described drill bit is provided with support, and anchor clamps are installed on the support, and anchor clamps are the products that need boring in order to lay.Drill bit is connected with motor, thereby drill bit is rotated.
Operation principle of the present utility model is:
The utility model is with the inflation of switch control cylinder, thereby pulling rope belt dynamic pressure wheel rotates, and makes the rack drives drill bit to lower slider, finishes boring.
The utility model has the advantages that:
The utility model is simple in structure, and cost of manufacture is low, and dependable performance, and practical safety can reduce labor intensity simultaneously.
Description of drawings
Fig. 1 is the enough schematic diagrames of knot of the present utility model.
The specific embodiment
Referring to Fig. 1, a kind of pneumatic drilling machine includes support 7, drill bit 5, and support 7 upper ends are slidingly fitted with tooth bar, are rotatablely equipped with pinch roller 1 on the tooth bar, and the lower end of tooth bar is fixed with drill bit 5, and drill bit 5 is connected with motor 6; The lower end of described support 7 is fixed with cylinder 4, is fixed with steel wire rope 2 on the piston rod of cylinder 4, and the other end of steel wire rope 2 is connected on the pinch roller 1 by back-moving spring, is connected with tracheae on the described cylinder 4, and the air inlet of tracheae is by switch 3 controls.
The below of described drill bit 5 is provided with support 8, and anchor clamps 9 are installed on the support 8.
