Abstract
The utility model discloses a porous brill drill bit, including having drive gear's final drive shaft and a plurality of drill bit, the drill bit includes drive end gear and drill lip end, the drill lip end stretches out the transmission case, and the drive end gear is located transmission case and final drive shaft's gear engagement, its characterized in that: the both ends of final drive shaft's the gear both ends and the drive end gear of drill bit are all overlapped and are equipped with thrust ball bearing to still be provided with the skeleton oil blanket outside stretching out transmission case end thrust ball bearing, and install the oil blanket board outside the skeleton oil blanket. Through using thrust ball bearing, the axial strength of drilling rod has been improved, adopt the skeleton oil blanket, improved leakproofness and lubricity in the porous brill drill bit transmission case, improved heat -sinking capability and cleanliness in the transmission case simultaneously, reduced porous brill drill bit's the frequency of maintaining.
Description
Technical field
The utility model belongs to a kind of machining tool, and relating to one concretely can as required, can the drill bit in the multiple hole of disposable processing.
Background technology
In order to improve crudy and working (machining) efficiency in existing machining tool, design various different process equipment, in rig, be designed with multi-hole drill drill bit, the such as patent No. is 201420035597.9, patent name is the patent of multi-hole drill drill bit connection structure, but this class formation is owing to being all enclosed in power transmission shaft and travelling gear in transmission case, do not consider the lubricant heat dissipation problem of gear and bearing, and space is narrower and small, lubricating system cannot design at inwall, drill lip and transmission case contact position are without oil sealing, lubricating oil cannot be preserved, dust is easily entered in inside.Drilling rod top adopts nut to lock simultaneously, rotates to produce to loosen, and cause bearing displacement, operating mode is poor, needs to carry out clean and maintenance simultaneously, add maintenance cost within the use short period.
Summary of the invention
In view of there is above problem, the utility model provides a kind of multi-hole drill drill bit, has structure simple, sealing and high lubricating effect and the feature of good heat dissipation effect.
A kind of multi-hole drill drill bit, comprise the final drive shaft with travelling gear and multiple drill bit, drill bit comprises drive end gear and drill lip end, described drill lip end stretches out transmission case, drive end gear is positioned at the gears meshing of transmission case and final drive shaft, it is characterized in that: the two ends of the gear two ends of described final drive shaft and the drive end gear of drill bit are all set with thrust ball bearing, and be also provided with outside framework oil seal stretching out outside transmission case end thrust ball bearing, and outside outside framework oil seal, oil seal plate is installed.The advantage of the technical program is exactly by arranging at the two ends of travelling gear and driven wheel the axial strength that thrust ball bearing improves power transmission shaft and drill bit, ensure that the perpendicularity of boring and datum plane; Simultaneously by arranging outside framework oil seal, more lubricant grease can be preserved, ensure that the lubricant effect of rotatable parts.Lubricant grease can be taken away because rotate the heat produced simultaneously, and radiating effect is relatively good, and by adding oil seal plate, improves the effect of blocking dust, ensure that the cleannes in transmission case.
Further: the upper and lower two ends of described transmission case are provided with upper cover and lower cover, described final drive shaft also and upper cover is provided with oil seal plate through upper cover, the drill lip end of described drill bit stretches out lower cover and also and between lower cover is provided with oil seal plate, and described oil seal plate is fixed by crossed countersunk head screw.The technical program structure is simple, ensure that the sealing in transmission case.
Further: the drive end gear two-wheeled of described drill bit and the two ends of main drive gear are detachable connection with being coordinated the drive end of described drill bit and drill lip end by needle bearing and transmission case body.The advantage of the technical program is by using needle bearing, improve its bearing capacity, take radial dimension little.
Further: the oil seal plate of described lower cover lower end is enclosed in down to cover through drill bit and is fixed by crossed countersunk head screw, prevent dust from entering possibility in transmission case further, ensure that the cleannes in transmission case.
beneficial effect
The beneficial effects of the utility model are: by using thrust ball bearing and outside framework oil seal, improve the axial strength of multi-hole drill drill bit, and sealing in transmission case and lubricity, improve the heat-sinking capability in transmission case and cleannes simultaneously, reduce the frequency of maintenance of multi-hole drill drill bit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model multi-hole drill drill bit.
Detailed description of the invention
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of multi-hole drill drill bit, comprise the final drive shaft 5 with travelling gear and multiple drill bit 6, drill bit comprises drive end gear and drill lip end, described drill lip end stretches out transmission case 1, drive end gear is positioned at the gears meshing of transmission case and final drive shaft, it is characterized in that: the two ends of the gear two ends of described final drive shaft and the drive end gear of drill bit are all set with thrust ball bearing 11, and be also provided with outside framework oil seal 4 stretching out outside transmission case end thrust ball bearing, and oil seal plate 8 is installed outside outside framework oil seal.The advantage of the technical program is exactly by arranging at the two ends of travelling gear and driven wheel the axial strength that thrust ball bearing improves power transmission shaft and drill bit, ensure that the perpendicularity of boring and datum plane, simultaneously by arranging outside framework oil seal, more lubricant grease can be preserved, ensure that the lubricant effect of rotatable parts, lubricant grease can be taken away because rotate the heat produced simultaneously, radiating effect is relatively good, and by adding oil seal plate, improve the effect of blocking dust, ensure that the cleannes in transmission case.
In the present embodiment: the upper and lower two ends of described transmission case are provided with upper cover 2 and lower cover 3, described final drive shaft also and upper cover is provided with oil seal plate 8 through upper cover, upper cover and lower cover are fixed on transmission case by soket head cap screw 12, the drill lip end of described drill bit stretches out lower cover and also and between lower cover is provided with oil seal plate 7, and described oil seal plate is fixed by crossed countersunk head screw.The technical program structure is simple, ensure that the sealing in transmission case.
In the present embodiment: the drive end gear two-wheeled of described drill bit and the two ends of main drive gear are detachable connection with being coordinated the drive end of described drill bit and drill lip end by needle bearing 9 and transmission case body.The advantage of the technical program is by using needle bearing, improve its bearing capacity, take radial dimension little.
In the present embodiment, the oil seal plate 7 of described lower cover lower end is enclosed in down to cover through drill bit to be fixed by crossed countersunk head screw.By arranging oil seal plate, preventing dust from entering possibility in transmission case further, ensure that the cleannes in transmission case.
