Problems solved by technology
[0002] At present, the drill bit is directly installed on the drill rig during use; the drill bit is directly connected to the motor shaft, and the speed of the drill bit is adjusted through the transmission; thus adapting to the hardness of the drilled object; but this kind of drill has a small adjustment range. ;It is inconvenient to use; the drill bit is often burned because the drill bit is too hard and the drill bit rotates too fast; it brings a lot of inconvenience to the user; so it is very necessary to design a drilling rig with a large adjustment range

specific Embodiment approach
[0053] The specific embodiment: when people use the drilling rig designed by the present invention, the driving motor 4 is controlled to make the driving motor 4 work; when the driving motor 4 works, the driving motor 4 can make the second rotating shaft 15 rotate; the second rotating shaft 15 rotates to drive the first The rotation of the bevel gear 5; the rotation of the first bevel gear 5 drives the rotation of the second bevel gear 6; the rotation of the second bevel gear 6 will drive the rotation of the first shaft 14; the rotation of the first shaft 14 drives the spherical friction ring 11 around the first shaft 14 The axis rotates; at this time, people adjust the relative position of the first installation shell 10 and the second installation shell 12 according to the hardness of the object to be drilled; that is, adjust the diameter of the matching position of the spherical friction ring 11 and the third gear 7; and then adjust the transmission to the speed and torque o...

The invention belongs to the technical field of drilling machines, and in particular, relates to an impact drilling machine capable of adjusting rotating speed. The drilling machine comprises a drillbit, a transmission mechanism and a driving mechanism; when people use the drilling machine, a driving motor is controlled to work to rotate a spherical friction ring; at this time, the people adjustrelative positions of a first mounting shell and a second mounting shell according to the hardness of drilled objects, so that the rotating speed and the torque of the drill bit achieve a matching state with the drilled objects; after adjustment is finished, users press the most front end of the drill bit to the drilled objects, so that a smooth surface of a third gear is contacted with the spherical friction ring; at this time, the spherical friction ring is rotated to drive rotation of the third gear through friction; the third gear is rotated to drive rotation of the drill bit for drilling;and the drilling machine adjusts the rotating speed and the torque transferred to the drill bit to enable the rotating speed and the torque of the drill bit to achieve the matching state with the drilled objects, so that overburning of the drill bit due to higher hardness of the drilled objects and higher rotating speed of the drill bit is prevented.
Description
technical field [0001] The invention belongs to the technical field of drilling rigs, in particular to an impact-type drilling rig with adjustable rotational speed. Background technique [0002] At present, the drill bit is directly installed on the drill rig during use; the drill bit is directly connected to the motor shaft, and the speed of the drill bit is adjusted through the transmission; thus adapting to the hardness of the drilled object; but this kind of drill has a small adjustment range. It is inconvenient to use; the drill bit is often burned because the drill bit is too hard and the drill bit rotates too fast; it brings a lot of inconvenience to the user; so it is very necessary to design a drilling rig with a large adjustment range. [0003] The present invention designs an impact-type drilling rig with adjustable rotating speed to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned defects in the prior art, the ...
