Description

Technical Field

[0001] This utility model relates to a novel high-efficiency drilling device for machining, belonging to the field of machining technology. Background Technology

[0002] Drill bits, as the most common cutting tools in hole machining, are widely used in mechanical manufacturing, especially for machining holes in parts such as cooling devices, tube sheets of power generation equipment, and steam generators, where their application is particularly extensive and important. In semi-automatic drilling equipment, the traditionally designed and installed speed stabilizer lacks structural buffering devices for the machining travel distance, and the drill bit lacks a cooling structure. Utility Model Content

[0003] The purpose of this invention is to provide a new type of high-efficiency drilling device for machining, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A novel high-efficiency drilling device for machining, comprising a main body, a stroke guide rod, a motor, a transmission box, a buffer-type speed stabilizer, a drive module, an external coolant bracket, and a drill bit. The stroke guide rods installed on both sides of the main body are synchronously positioned and installed with the drive module. The motor is connected to the drill bit shaft through the transmission box. The drive module frame is embedded in the main body and connected to the drill bit module. The external coolant bracket is positioned and installed on the outer diameter of the drill bit housing.

[0005] Preferably, the external coolant bracket consists of a sleeve, an L-shaped bracket, an inlet pipe, and a V-shaped outlet pipe. The L-shaped bracket is vertically welded to the outer diameter of the sleeve, and the inlet pipe and the V-shaped outlet pipe at the end of the crossbar of the L-shaped bracket are connected and positioned.

[0006] Preferably, the inlet pipe is connected to external coolant via a pipeline.

[0007] Preferably, the buffer-type speed stabilizer consists of a speed-stabilizing hydraulic rod, a positioning block, a buffer spring assembly, and a rubber pad. Positioning blocks are fixedly installed on both sides of the front end of the speed-stabilizing hydraulic rod frame, and the positioning blocks are positioned and installed by the buffer spring assembly and the rubber pad.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The buffer-type speed stabilizer consists of a speed-stabilizing hydraulic rod, a positioning block, a buffer spring assembly, and a rubber pad. The positioning block, which is set at the front of the buffer-type speed stabilizer, works with the buffer spring assembly and the rubber pad to provide structural buffering during the movement of the drive module frame. The drive module frame first contacts the rubber pad and then moves to the depth position set by the top rod of the speed-stabilizing hydraulic rod, thus completing the elastic buffering of the entire stroke.

[0010] The external coolant rack consists of a sleeve, an L-shaped bracket, an inlet pipe, and a V-shaped outlet pipe. The inlet pipe, together with the V-shaped outlet pipe, supplies coolant from both sides of the drill bit, reducing irregular splashing. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4 As shown, a novel high-efficiency drilling device for machining includes a main body 1, a stroke guide rod 2, a motor 3, a transmission box 4, a buffer-type speed stabilizer 5, a drive module 6, an external coolant bracket 7, and a drill bit 8. The stroke guide rods 2 installed on both sides of the main body 1 are synchronously positioned and installed with the drive module 6. The motor 3 is connected to the rotating shaft of the drill bit 8 through the transmission box 4. The drive module 6 is embedded in the frame and installed inside the main body 1 and is connected to the drill bit 8 module. The external coolant bracket 7 is positioned and installed on the outer diameter of the drill bit 8 housing.

[0018] The external coolant support 7 consists of a sleeve 9, an L-shaped bracket 10, an inlet pipe 11, and a V-shaped outlet pipe 12. The L-shaped bracket 10 is vertically welded to the outer diameter of the sleeve 9. The inlet pipe 11 and the V-shaped outlet pipe 12 at the end of the crossbar of the L-shaped bracket 10 are connected and positioned. The inlet pipe 11 and the V-shaped outlet pipe 12 supply coolant at an angle from both sides of the drill bit. During the rotation of the drill bit, some of the cutting fluid impact force is buffered, reducing irregular splashing.

[0019] The inlet pipe 11 is connected to external coolant via a pipeline.

[0020] The buffer-type speed stabilizer 5 consists of a speed-stabilizing hydraulic rod 13, a positioning block 14, a buffer spring assembly 15, and a rubber pad 16. The positioning block 14 is fixedly installed on both sides of the front end of the speed-stabilizing hydraulic rod 13. The positioning block 14 is positioned by the buffer spring assembly 15 and the rubber pad 16. The positioning block 14, in conjunction with the buffer spring assembly 15 and the rubber pad 16, provides structural buffering for the drive module 6 frame during its movement. The drive module 6 frame first contacts the rubber pad 16 and then moves to the depth position set by the top rod of the speed-stabilizing hydraulic rod 13, thus completing the elastic buffering of the entire stroke.

[0021] Specific usage: A new type of high-efficiency drilling device for machining. This device is designed to provide structural buffering and cooling for the drilling process during the drilling depth stroke. The positioning block set in front of the buffer-type speed stabilizer, together with the buffer spring group and the rubber pad, provides structural buffering for the drive module frame during its movement. The drive module frame first contacts the rubber pad and then moves to the depth position set by the speed stabilizing hydraulic rod, completing the elastic buffering of the entire stroke. The inlet pipe and the V-shaped outlet pipe supply coolant from both sides of the drill bit to reduce irregular splashing.

[0022] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
