Technical Field

[0001] The utility model relates to the technical field of transmission shafts, in particular to a drilling device used for producing a steering transmission shaft of a harvester. Background Art

[0002] The drive shaft is a rotating body with high speed and few supports, so its dynamic balance is very important. Generally, the drive shaft must be subjected to dynamic balancing test and adjusted on a balancing machine before leaving the factory. For front-engine rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be composed of several sections, and the sections can be connected by universal joints.

Through the reinforcing plates 4, the support frames 208 and the bottom plate 1 can be fixed, enhancing the stability of the device and preventing it from shifting and becoming unstable during use.

[0028] See Figure 1 , Figure 2 and Figure 3 , the telescopic end of the first electric telescopic rod 210 is fixedly connected to a first drill bit 211. Fixed rings 212 are fixedly connected to the outer surfaces of each group of support frames 208. Three fixed shafts 213 are fixedly connected to the inner walls of each fixed ring 212. A first sliding groove 205 is formed on the upper surface of the fixed frame 207. A protective seat 5 is fixedly connected to the outer surface of the first electric telescopic rod 210. The right side surface of the protective seat 5 is fixedly connected to the left side surface of the support block 204. Through the protective seat 5, the first electric telescopic rod 210 can be protected, having a strong protective effect and preventing it from being damaged during use.

[0029] See Figure 4 , Figure 5 and Figure 8 , two groups of second sliding grooves 217 are formed at one end of the rotating disk 206 away from the driving motor 209. Two first sliding blocks 218 are slidably connected to the inside of each group of second sliding grooves 217.

Through the protective shell 7, the second electric telescopic rod 221 can be protected, effectively avoiding the problem of being damaged by the outside during its working process.

[0031] Working principle: When in use, first pass the transmission shaft through the two fixing rings 212, then fix one end of the transmission shaft on the rotating disk 206, and make the first sliding block 218 slide in the second sliding groove 217 through the threaded rod 216, so that the clamping plate 219 clamps and fixes the transmission shaft. When drilling the axis of the transmission shaft is required, by making the output end of the driving motor 209 rotate, the rotating disk 206 is driven to rotate, so that the transmission shaft can be driven to rotate. Then, by making the telescopic end of the first electric telescopic rod 210 extend, the first drill bit 211 can be driven to move, so that the axis of the transmission shaft can be drilled, enhancing the practicability of the device. When drilling the surface of the transmission shaft is required, only need to make the telescopic end of the third electric telescopic rod 222 extend, driving the second drill bit 223 to move downward, so that the surface of the transmission shaft can be drilled. And by making the telescopic end of the second electric telescopic rod 221 contract, the second sliding block 220 can be made to move in the first sliding groove 205, thereby driving the second drill bit 223 to move, enhancing the use effect of the device. And during drilling, the generated debris will fall into the debris collection box 203 below the transmission shaft. Then, by using the pulling handle 215, the drawer 214 can be opened, so that the debris generated by drilling can be recycled. It can effectively avoid the problems that when drilling the transmission shaft, the fixation is not firm, which is likely to cause the transmission shaft to shake, resulting in unstable drilling work and inaccurate drilling, and a large amount of impurities are generated during the drilling work, accumulating in the equipment, leading to a reduction in the service life of the equipment and a reduction in the processing quality.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
