Abstract
The utility model designs an adjustable beating device used for boring and enlarging the bottom of a hole, which essentially comprises a beating mechanism, an adjusting mechanism, a gas cylinder and an aiguille located at the bottom. The aiguille is an aiguille used for boring special holes; the beating mechanism comprises a beating rod and a beating connecting plate which is movably connected with the beating rod; the adjusting mechanism comprises a gear spline housing, an internal threaded spline shaft, an external threaded shaft and an adjusting gear; the adjusting gear is in transmission connection with the gear spline housing inside which the internal threaded spline shaft is arranged; the internal threaded spline shaft is connected with the external threaded shaft; a self-aligning bearing which serves as an eccentric fulcrum is arranged above the aiguille; and a single-key positioning plate is connected on the external threaded shaft. The beating device is convenient to adjust, simple to operate, easy to control and large in adjusting range; and the aiguille can rotate annularly to enlarge the bottom of the hole.
Description
Technical field
The design relates to a kind of back of the body bolt that bores the deflection device in special type hole is installed on plate.
Background technology
Present brill, open up the hole machine exist unreasonable structure, regulate inconvenient, adjustable range is narrow and defective wayward, that operation is difficult.
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of easy to adjust, simple to operate, adjustable range are big, the adjustable drilling that is easy to control, open up the deflection device at the bottom of the hole.
The technical scheme that the utility model technical solution problem is adopted is: a kind of adjustable drilling, open up the deflection device at the bottom of the hole, it mainly comprises beat mechanism, governor motion, cylinder and the drill bit that is positioned at the bottom, drill bit is the drill bit that bores extraordinary hole, swinging mechanism comprises beat bar and beat brace, beat bar and beat brace flexibly connect, described governor motion comprises the gear spline cover, the internal thread splined shaft, external screw thread axle and adjusting gear, adjusting gear and gear spline cover are in transmission connection, be provided with the internal thread splined shaft in the gear spline cover, the internal thread splined shaft is connected with the external screw thread axle, described drill bit top has been provided with the self-aligning bearing of eccentric point action, is connected with the singly-bound spacer on the described external screw thread axle.Described beat mechanism is in transmission connection by decelerator and motor.Be provided with the external screw thread axle in the described internal thread splined shaft, internal thread splined shaft and external screw thread axle are by being threaded.Described cylinder is connected with the beat brace with the beat bar by governor motion.Be dynamically connected till described singly-bound spacer and the external screw thread axle.
The beneficial effects of the utility model are: easy to adjust, simple to operate, adjustable range is big, be easy to control, but the rotation of drill bit ring-type realizes opening up at the bottom of the hole big.
Description of drawings
Fig. 1 is this adjustable drilling, the schematic diagram when opening up the deflection device boring fine setting at the bottom of the hole;
Fig. 2 is this adjustable drilling, open up deflection device at the bottom of the hole opens up schematic diagram when regulating at the bottom of the hole;
Among the figure: beat bar 1, beat brace 2, gear spline cover 3, internal thread splined shaft 4, external screw thread axle 5, adjusting gear 6, cylinder 7, self-aligning bearing 8, clutch shaft bearing 8.1, second bearing 8.2, the 3rd bearing 8.3, singly-bound spacer 9, decelerator 10, motor 11.
The specific embodiment
As shown in Figure 1, the described adjustable drilling of the utility model, open up the deflection device at the bottom of the hole, it mainly comprises beat mechanism, governor motion, cylinder 7 and the drill bit 12 that is positioned at the bottom, beat mechanism comprises beat bar 1 and beat brace 2, beat bar 1 and beat brace 2 flexibly connect, governor motion comprises gear spline cover 3, internal thread splined shaft 4, external screw thread axle 5 and adjusting gear 6, adjusting gear 6 and gear spline cover 3 are in transmission connection, be provided with internal thread splined shaft 4 in the gear spline cover 3, the gear spline cover 3 outer clutch shaft bearings 8.1 that are provided with, internal thread splined shaft 4 is connected with external screw thread axle 5, external screw thread axle 5 is located in the screw thread splined shaft 4, internal thread splined shaft 4 and external screw thread axle 5 are provided with clutch shaft bearing 8.1 by being threaded in the internal thread splined shaft 4, external screw thread axle 5 is provided with second bearing 8.2.Drill bit 12 tops have been provided with the self-aligning bearing 8 of eccentric point action, be connected with singly-bound spacer 9 on the described external screw thread axle 5, be dynamically connected till singly-bound spacer 9 and the external screw thread axle 5, beat mechanism is in transmission connection by decelerator 10 and motor 11, and cylinder 7 is connected with beat brace 2 with beat bar 1 by governor motion.
During use, governor motion makes internal thread splined shaft 4 and 5 specific elongations of external screw thread axle by adjusting gear 6 clockwise direction rotating band moving gear spline housing 3 rotations counterclockwise, otherwise shorten, the beat bar 1 of deflection swinging mechanism and the angle of beat brace 2 diminish, main shaft departs from the low-angle in center, realize the fine setting of boring, see Fig. 1.
When executing agency's cylinder 7 down promotes, with internal thread spline housing 4 with external screw thread axle 5 directly by spline housing down mobile significantly after, the angle of beat bar 1 and beat brace 2 is become more hour, main shaft departs from the wide-angle in center, the adjusting at the bottom of the hole is opened up in realization, sees Fig. 2.
The setting of singly-bound spacer 9 is in order to prevent the rotation of external screw thread axle 5.
