Description

Technical Field

[0001] This invention relates to the field of polishing machine technology, specifically to a multi-axis linkage drill bit edge polishing integrated machine and its control method. Background Technology

[0002] Multi-axis linkage drill bit edge polishing integrated machine is a high-precision processing equipment that integrates multiple functions. Through the coordinated movement of multiple axes, it can perform all-round and multi-angle polishing of drill bit edges. This equipment usually adopts CNC technology to realize automated operation and improve polishing efficiency and quality. The cutting edge of a drill bit is the cutting part of the drill bit, usually located at the front end of the drill bit. It has a sharp edge and a specific geometry, used to drill or cut in materials. The design and quality of the cutting edge directly affect the cutting efficiency, accuracy and service life of the drill bit. A good cutting edge design can reduce cutting force, increase cutting speed, and at the same time ensure the roundness and surface finish of the drilled hole. In the operation of a multi-axis linkage drill bit edge polishing machine, in order to ensure the quality and efficiency of polishing, it is usually necessary to precisely fix each drill bit and ensure that the position and height of each drill bit are consistent.

[0013] A control method for a multi-axis linkage drill bit edge polishing integrated machine; Step 1: When feeding the drill bit body, the second servo motor is started to drive the transmission column to rotate. The transmission column is connected to the inside of the lug. The rotation of the transmission column drives the clamping block and the fixing assembly to rotate as a whole. The fixing assembly faces downward. The linear motor is started to drive the transmission block, the position control assembly and the fixing assembly to move downward. The transmission block slides on the outside of the guide column. After the permanent magnet column is aligned with the electromagnet, the electromagnet is started to generate magnetic force. The electromagnet and the permanent magnet column repel each other magnetically, and the permanent magnet column moves backward. The permanent magnet column drives the ring plate to move. The permanent magnet column slides inside the sleeve. The ring plate stretches the spring. The fixing clamping plate moves away from the clamping block. The position control assembly and the fixing assembly move downward. The drill bit body inside the insertion sleeve will enter between the fixing clamping plate and the clamping block.

Step 2: When fixing multiple drill bit bodies, start the linear motor to continue driving the position control component and the fixing component to move upward simultaneously. The drill bit body is close to the polishing machine. Insert the insert block into the interior of multiple slots. The rear end of the frame plate is fixedly connected to the transmission block by bolts. The fixing clamping plate presses tightly against the drill bit body. The arc-shaped clamping grooves opened on both the fixing clamping plate and the clamping block adjust the position of the drill bit body. An extension seat is fixedly connected to the lower part of the rear end of the frame plate. Step 3: To achieve continuous processing of the drill bit body, remove multiple insert blocks. The second servo motor controls the entire drill bit body to face downwards. Start the first servo motor to drive the threaded rod to rotate. The threaded rod drives the internal threaded block to move. The internal threaded block slides inside the rail groove. After the unloaded insert is aligned with the drill bit body, the permanent magnet column is aligned with the electromagnet. Start the electromagnet, and the fixed clamping plate and clamping block move away. Under the action of gravity, the drill bit body falls into the unloaded insert. Control the first servo motor to align the insert with the arc-shaped clamping groove.

[0020] As a further implementation of this solution, the machine tool assembly 1 includes a base 11, a frame 12 fixedly connected to the top of the base 11, a horizontal plate 13 fixedly connected to the rear end of the frame 12, and multiple electromagnets 14 fixedly connected to the rear end of the horizontal plate 13. Through the above settings, the drill bit is stably fixed and multi-point magnetic control is achieved, while simplifying the operation and reducing the difficulty and time cost. As a further implementation of this solution, the material transfer assembly 2 includes a rail plate 21 with a rail groove 22 at the upper end. A first servo motor 23 is fixedly connected to the right side of the rail plate 21. A threaded rod 24 is fixedly connected to the end of the main shaft of the first servo motor 23. The threaded rod 24 is rotatably connected to the inner side of the rail plate 21. The bottom end of the rail plate 21 is fixedly connected to the upper end of the base 11.

The first servo motor 23 drives the threaded rod 24 to rotate, thereby controlling the movement of the internal threaded block 25, thus achieving the effect of rapid and continuous processing, significantly improving production efficiency, reducing downtime during processing, and improving ease of use. As a further implementation of this solution, the polishing assembly 3 includes a linear motor 31, with a transmission block 32 fixedly connected to the front end of the linear motor 31. A guide column 33 is slidably connected to the inner side of the transmission block 32.

A top block 34 is fixedly connected to the upper end of the guide column 33. A polishing machine 35 is fixedly connected to the front end of the top block 34. The polishing machine 35 is located above the second servo motor 41. An ear seat 38 is fixedly connected to the front end of the transmission block 32. A rotating hole is opened on the inner side of the ear seat 38. The rotating hole of the ear seat 38 is rotatably connected to the transmission column 42 through a bearing. The right side of the right ear seat 38 is fixedly connected to the housing of the second servo motor 41. Through the above settings, multi-axis linkage control of the drill bit is realized. By rotating the transmission column 42, the drill bit is driven to perform all-round and multi-angle polishing treatment, which further improves the precision and quality of polishing, and at the same time improves the flexibility and response speed of the equipment.

As a further implementation of this solution, the front end of the clamping block 43 is tightly attached to the rear end of the fixed clamping plate 51, and the inner side of the clamping block 43 and the inner side of the sleeve 44 are slidably connected to the permanent magnet column 53. The inner side of the sleeve 44 is fixedly connected to the rear end of the spring 54. Through the above settings, the positional stability of the drill bit during the polishing process is ensured, further improving the precision and quality of polishing, while also improving the stability and reliability of the equipment.

[0021] Workflow: When feeding the drill bit body 6, the second servo motor 41 is activated to drive the transmission column 42 to rotate. The transmission column 42 is rotatably connected to the inner side of the lug 38. The rotation of the transmission column 42 drives the clamping block 43 and the fixing component 5 to rotate as a whole. When the fixing component 5 faces downward, the linear motor 31 is activated to drive the transmission block 32, the position control component 4, and the fixing component 5 to move downward. The transmission block 32 slides on the outside of the guide column 33. The design of the guide column 33 can improve the stability of the support for the position control component 4 and the fixing component 5. When the permanent magnet column 53 is aligned with the electromagnet 14, the electromagnet 14 is activated to generate magnetic force, causing the electromagnet 14 and the permanent magnet column 53 to repel each other magnetically. Under the action of the repulsive force, the permanent magnet column 53 moves backward, driving the ring plate 55 to move. The permanent magnet column 53 slides on the sleeve. Inside 44, the ring plate 55 stretches the spring 54. At this time, the fixed clamping plate 51 and the clamping block 43 move away from each other. The control component 4 and the fixed component 5 move downward in the control position. Since there are multiple electromagnets 14 moving downward, the fixed clamping plate 51 and the clamping block 43 remain far apart when moving downward. At this time, the drill bit body 6 inside the insertion cylinder 26 will enter between the fixed clamping plate 51 and the clamping block 43 until the top of the drill bit body 6 is in close contact with the plane of the top of the clamping block 43. Then the electromagnet 14 is de-energized. Under the elastic force of the spring 54, the fixed clamping plate 51 is reset. The drill bit body 6 is clamped between the fixed clamping plate 51 and the clamping block 43, thereby achieving the effect of temporarily positioning the drill bit body 6. The second servo motor 41 is started to drive the transmission column 42 to rotate, so that the fixed component 5 faces upward, thereby achieving the effect of feeding. When fixing multiple drill bit bodies 6, the linear motor 31 is started to drive the position control component 4 and the fixing component 5 to move upward simultaneously, so that the drill bit body 6 is close to the polishing machine 35. The insert block 37 is inserted into the interior of multiple slots 56. Then, the rear end of the frame plate 36 is fixedly connected to the transmission block 32 by bolts. During the fixing process, the permanent magnet column 53 drives the fixing clamp plate 51 to move backward through the pressing of the bolts, so that the fixing clamp plate 51 presses tightly against the drill bit body 6. The arc-shaped clamping grooves 52 opened on both the fixing clamp plate 51 and the clamping block 43 automatically adjust the position of the drill bit body 6. The lower part of the rear end of the frame plate 36 is fixedly connected to the extension seat, so as to achieve the effect of fixing multiple drill bit bodies 6 at the same time. This can prevent the fixing clamp plate 51 and the clamping block 43 from moving away from each other when processing the drill bit body 6, thereby improving the accuracy of processing the drill bit body 6. At the same time, this fixing method can ensure the positional accuracy of the drill bit body 6 and ensure the quality of subsequent processing. When continuously processing the drill bit body 6, after the drill bit body 6 is processed by the polishing machine 35, multiple insert blocks 37 are removed. The second servo motor 41 controls the entire drill bit body 6 to face downwards. The first servo motor 23 is started to drive the threaded rod 24 to rotate. The threaded rod 24 drives the internal threaded block 25 to move. The internal threaded block 25 slides inside the rail groove 22. When the unloaded insert 26 is aligned with the drill bit body 6, the permanent magnet column 53 is aligned with the electromagnet 14. The electromagnet 14 is started. Under the action of magnetic repulsion, the fixed clamping plate 51 is controlled to move away from the clamping block 43. Under the action of gravity, the drill bit body 6 falls into the unloaded insert 26. The first servo motor 23 is then controlled to align the insert 26 containing the drill bit body 6 with the arc-shaped clamping groove 52. The same process of moving away is repeated to reload the drill bit body 6, thereby achieving a rapid and continuous processing effect and improving the convenience of use.
