Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, an embodiment of the present invention is shown: a straight shank alloy drill bit comprises a drill bit 3, a fixed rod 1 is installed at the upper end of the drill bit 3, an adjusting and blocking mechanism 2 is fixedly installed on the outer wall of the fixed rod 1, the adjusting and blocking mechanism 2 comprises a bearing 4, an adjusting device 5, a measuring plate 6 and a connecting disc 7, the connecting disc 7 is rotatably installed on the outer portion of the bearing 4, the measuring plate 6 is fixedly installed on the edge of the bottom end face of the connecting disc 7 in a circular distribution manner, the adjusting device 5 is fixedly installed in the middle of the bottom end face of the connecting disc 7 in a circular distribution manner, length indications 8 are arranged on the side end faces of the measuring plate 6, the adjusting device 5 comprises a threaded rod 9, a threaded ring 10, a pointer 11 and a support rod 12, the threaded ring 10 is rotatably installed on the threaded rod 9, the pointer 11 is fixedly installed on the edge of the bottom end face of the threaded ring, the bottom end face of the shock absorption column 13 is fixedly provided with a mounting sleeve 14, the inside of the mounting sleeve 14 is rotatably provided with a ball 15, the drill bit 3 is quickly and fixedly connected with a drilling device through the fixing rod 1, the position of the screw thread ring 10 on the threaded rod 9 is quickly adjusted according to the drilling depth in the process of drilling by using the drill bit 3, the indication number of the pointing length of the pointer 11 on the indication number 8 is the length difference between the end of the drill bit 3 and the end ball 15 of the support rod 12, the pointer 11 can be correspondingly pointed on the indication number 8 by screwing the screw thread ring 10 up and down, when the drill bit 3 drills a slotted hole with the specified depth, the ball 15 arranged at the bottom end of the support rod 12 is in rotating contact with the outer edge face of a workpiece, and because the connecting disc 7 is rotatably arranged on the outer wall of the bearing 4, the rotating speed of the connecting disc 7 is greatly reduced when the inner, and the ball 15 rotatably mounted at the bottom end of the support rod 12 can effectively prevent the bottom end of the support rod 12 from rigidly colliding with the surface of the workpiece.
The measuring plate 6 is located the outside of pointer 11 and bracing piece 12, and pointer 11 horizontal directional length registration 8, the material of shock attenuation post 13 is rubber, the draw-in groove has been seted up to the inside of installation sleeve 14, and ball 15 rotates the inside of joint at the draw-in groove, pointer 11 directional length registration 8 goes up is the length difference of the end of drill bit 3 and the end ball 15 department of bracing piece 12, the drill center of the drill bit 3 working part should be even 1 direction bodiness to dead lever, every 100mm bodiness 1.4-1.8mm, there is great extrusion force between the surface of big crescent bracing piece 12 and work piece along with pressing in the process of punching, consequently bracing piece 12 and connection pad 7 can stall, bracing piece 12 plays spacing effect to drill bit 3 this moment, just can not continue the drilling downwards again after the slotted hole 3 drills out the appointed degree of depth promptly.
The working principle is as follows: the drill bit 3 is fast and fixedly connected with the drilling equipment through the fixed rod 1, the position of the screw thread ring 10 on the threaded rod 9 is fast adjusted according to the drilling depth in the process of drilling by using the drill bit 3, the pointer 11 is correspondingly pointed on the length indication 8 because the indication number on the indication 8 of the pointing length of the pointer 11 is the length difference between the end of the drill bit 3 and the end ball 15 of the supporting rod 12, the pointer 11 is correspondingly pointed on the indication number 8 by screwing the screw thread ring 10 up and down, when the drill bit 3 drills a groove hole with the specified depth, the ball 15 arranged at the bottom end of the supporting rod 12 is in rotational contact with the outer edge surface of a workpiece, and the connecting disc 7 is rotationally arranged on the outer wall of the bearing 4, so that the rotating speed of the connecting disc 7 is greatly reduced when the inner ring of the bearing 4 rotates at high speed, and the ball 15 rotationally arranged at the bottom end of the supporting rod 12, and along with the pressing force which is increased gradually in the punching process, a larger extrusion force exists between the supporting rod 12 and the outer surface of the workpiece, so that the supporting rod 12 and the connecting disc 7 stop rotating, at the moment, the supporting rod 12 plays a limiting role in the drill bit 3, namely, the drill bit 3 can not drill downwards any more after drilling a slotted hole with a specified depth.
