[0002] Drill bit automatic processing equipment is a machine that can automatically complete the grinding and grinding of drill bits. These devices play a vital role in the manufacturing industry, especially in production lines that require a large number of drilling operations.

[0003] At present, when the drill bit is rotating, the drill bit may not be able to drill normally due to the hardness of the material, resulting in wear of the drill bit. Generally, the drill rod and the Z-axis may bend, causing serious accidents to the machine itself and effectively reducing the service life of the drill bit. In particular, after the drill bit is stuck on the sheet material, it takes a long time to separate the drill bit and the sheet material. Moreover, the power of the machine itself cannot be used to assist manual separation of the drill bit and the sheet material, which reduces the functionality of the machine, increases manual labor, and wastes a lot of time.

[0016] Furthermore, the lower end of the soft scraper is pressed against one side of the upper end surface of the processed sheet material.

[0017] A method for using a drill bit automated processing device, the specific method steps are as follows:

[0018] S1, drilling: start the Y-axis moving device 11, move the X-axis moving device to the position where the drilling is required, then start the Z-axis moving device to drive the drill bit to move downward, and then start the driving device to drive the drill bit to rotate, so that the rotating drill bit gradually drills a hole on the upper end surface of the processed sheet;

[0019] S2. Fixation: The scraper plate and the soft scraper member are used as bearing points, so that the scraper rod can slide upward inside the through hole, and the scraper plate and the soft scraper member are tightly pressed against the upper end surface of the processed sheet material by the rebound force of the third spring body, which can effectively increase the fixation of the processed sheet material;

[0020] S3, detection: when the drill bit moves downward, the detection rod slides upward in the sliding hole at a uniform speed. At the same time, the limit plate 25 drives the pressure sensor upward to contact the lower end surface of the pressure rod. Under the uniform pressure, the pressure sensor forces the pressure rod to slide upward inside the sliding hole and presses the second spring body upward. When the drill bit cannot drill, the pressure value remains unchanged or the pressure change is not large. The dwell time is 3 to 5 seconds. When the controller receives a signal, the Z-direction moving device and the driving device are stopped;

[0021] S4, iron chips collection: start the hydraulic cylinder to drive the transmission plate to press downward against the rack plate, and the rack plate meshes with the gear to one side, so that the gear drives the rotating shaft and the pressing plate to rotate downward clockwise. As the rotating shaft rotates gradually, one side of the soft scraper contacts the upper end surface of the processed sheet material, and then gradually rotates, one side of the soft scraper gradually pushes the iron chips generated by processing to the middle and collects them;

[0022] S5. Assistance: Continuing with the working movement of the fourth step, the rounded corner of one side of the pressure plate contacts the upper end surface of the processed sheet. At this time, start the Z-axis moving device to move the L-shaped moving plate upward. At the same time, one side of the pressure plate presses downward, thereby pushing the processed sheet and the drill bit downward. This step can be performed manually, and the force of the machine itself can be used to assist the manual work.

[0023] Beneficial effects:

[0024] In the present invention, the scraper and the soft scraper are tightly pressed against the upper end surface of the processed sheet material by the resilience of the third spring body, which can effectively increase the fixity of the processed sheet material and avoid the loosening of the processed sheet material due to excessively high drill speed.

[0025] In the present invention, when the drill bit cannot drill again, the pressure value generated by the pressure sensor remains unchanged or the pressure fluctuation is small. The pressure value at this time is transmitted to the controller. The controller receives the signal and stops its Z-axis moving device and driving device, which can automatically protect the drill bit, avoid jamming, avoid major damage to the processed sheet material, and avoid Z-axis bending due to excessive pressure in the Z-axis movement. Therefore, the service life of the drill bit is increased, the protection is improved, and the functionality is improved.

[0026] In the present invention, one side of the soft scraper gradually pushes and concentrates the iron chips generated by processing to the middle, so there is no need to manually clean the upper end surface of the processed sheet material. The soft scraper concentrates the iron chips in the middle of the processed sheet material, which can reduce workload and time and improve convenience.

[0027] In the present invention, the force of the machine itself can be used to assist manual labor through the pressing of the pressing plate, which can save a lot of time, reduce work labor, and improve the functionality of the machine. BRIEF DESCRIPTION OF THE DRAWINGS

When the drill bit moves downward, the detection rod 252 and the V-shaped plate 28 first press against the upper end surface of the processing sheet 5, and the drill bit performs drilling work under the uniform movement of the L-shaped moving plate 151, wherein the detection rod 252 and the V-shaped plate 28 are subjected to the resistance of the upper end surface of the processing sheet 5, so that the detection rod 252 slides upward in the sliding hole 22 at a uniform speed, and at the same time, the limit plate 25 slides upward inside the limit hole 22 and stretches upward on the first spring body 251, and the pressure sensor 252 on the limit plate 25 contacts the lower end surface of the pressing rod 27, and the pressure sensor 252 is pressed at a uniform speed. , so that the pressure rod 28 is forced to slide upward inside the sliding hole 22 and press upward on the second spring body 26. When the drill bit cannot drill again, the pressure value generated by the pressure sensor 252 remains unchanged or the pressure fluctuation is small. The pressure value at this time is transmitted to the controller. The controller receives the signal and stops the Z-direction moving device 14 and the driving device 15. It can automatically protect the drill bit, avoid jamming, avoid major damage to the processed sheet 5, and avoid Z-axis bending due to excessive pressure of Z-direction movement, thereby increasing the service life of the drill bit, improving protection, and improving functionality.

[0041] In this embodiment, a V-shaped plate 28 is fixedly connected to the outer side of the lower end surface of the detection rod 24, and the lower end surface of the V-shaped plate 28 is pressed against the upper end surface of the processed sheet 5, and the lower end surface of the V-shaped plate 28 is lower than the lower end surface of the drill bit. The pressure value can be accurately detected by the area of ​​the detection rod and the V-shaped plate 28.

[0042] In this embodiment, the extension mechanism 3 includes a placement groove 152 fixedly opened at the lower part of one side of the L-shaped movable plate 151, and a hydraulic cylinder 31 is fixedly connected to the upper part of the placement groove 152. The output end of the hydraulic cylinder 31 is connected to the telescopic rod 32, and the lower end of the telescopic rod 32 is fixedly connected to a transmission shell 33. The transmission shell 33 is transmission-connected to a first transmission assembly 34 and a second transmission assembly 35 through a first fixed rod and a second fixed rod. The second transmission assembly 35 includes a transmission plate 351 transmission-connected to the second fixed rod, and the lower part of the transmission plate 351 is connected to a rack plate 352 through a third fixed rod. A sliding plate 353 is fixedly connected to one side of the rack plate 352, and the sliding plate 353 is slidably fitted in a transmission groove 354 opened at the lower part of one side of the L-shaped movable plate 151, and the rack plate 352 is meshed with a gear 355. The hydraulic cylinder 31 is started to drive the telescopic rod 32 to move downward, and the transmission housing 33 is forced to press downward on the two transmission plates 351, and the transmission plate 351 is forced to press downward on the rack plate 352. The rack plate 352 is forced to slide to one side inside the transmission groove 354 through the sliding plate 353, and its rack plate 352 is engaged with the gear 355, so that the gear 355 drives the rotating shaft 356 to rotate clockwise in the rotating holes of the first support plate 3561 and the second support plate 3562, and the rotating shaft 356 drives the pressing plate 357 to rotate downward clockwise, which can realize the transformation of working action, from up and down motion to linear reciprocating motion, and reciprocating motion to circular rotation motion.

[0043] In this embodiment, a rotating shaft 356 is sleeved inside the gear 355, and both ends of the rotating shaft 356 are rotatably matched with a first support plate 3561 and a second support plate 3562, and a pressure plate 357 is fixedly connected in the middle of the rotating shaft 356, and one side of the pressure plate 357 is rounded. As the rotating shaft 356 gradually rotates, one side of the soft scraper 47 abuts against the upper end surface of the processed sheet 5. During the gradual rotation, one side of the soft scraper 47 gradually pushes and concentrates the iron filings generated by the processing to the middle, so that the upper end surface of the processed sheet 5 can be completely cleaned without manual work, until the rounded corner on one side of the pressure plate 357 abuts against the upper end surface of the processed sheet 5. At this time, the Z-direction moving device 14 is started to allow the L-shaped moving plate 151 to move upward. At the same time, one side of the pressure plate 357 is pressed downward, thereby pushing the processed sheet 5 and the drill bit downward. This step can be performed manually, and the power of the machine itself can be used to assist manual work, which can save a lot of time and reduce labor.

[0044] In this embodiment, one side of the pressing plate 357 presses against one side of the upper end surface of the processing plate 5, and the first transmission assembly 34 and the second transmission assembly 35 have the same structural position, which is beneficial to assist manual work with the power of the machine itself.

[0045] In this embodiment, the scraper mechanism 4 includes a fixed plate 41 fixedly connected to one side of the pressure plate 357, a through hole 42 is opened in the middle of the fixed plate 41, a scraper rod 43 is slidably fitted inside the through hole 42, the upper end surface of the scraper rod 43 is fixedly connected to a pressure plate 44, the lower end surface of the pressure plate 44 is fixedly connected to a third spring body 45, the lower end surface of the third spring body 45 is fixed to the upper end surface of the fixed plate 41, the lower end surface of the scraper 43 is fixedly connected to a scraper 46, and the lower end surface of the scraper 46 is provided with a soft scraper 47. The soft scraper 47 first presses against the upper end surface of the processing sheet 5, and the drill bit continues to drill downward. The soft scraper 47 gradually bends, allowing the scraper 46 to contact the processing sheet 5, and then continues to drill downward, so that the scraper 46 and the soft scraper 47 are subjected to force as bearing points, allowing the scraper rod 43 to slide upward inside the through hole 42 under the reverse force, and be stretched upward to the third spring body through the pressure plate 4. The scraper 46 and the soft scraper 47 are tightly pressed against the upper end surface of the processing sheet 5 through the rebound force of the third spring body 45, which can effectively increase the fixity of the processing sheet 5 and avoid the loosening of the processing sheet 5 due to the excessively high rotation speed of the drill bit.

[0046] In this embodiment, the lower end of the soft scraper 47 is pressed against one side of the upper end surface of the processing sheet 5. This is beneficial for not only pressing the processing sheet, but also pushing the iron chips for concentration.

[0047] A method for using a drill bit automated processing device, the specific method steps are as follows:

[0048] S1, drilling: start the Y-axis moving device 11 and the X-axis moving device 13 to move to the position where the drilling is required, then start the Z-axis moving device 14 to drive the drill bit to move downward, and then start the driving device 15 to drive the drill bit to rotate, so that the rotating drill bit gradually drills a hole on the upper end surface of the processed sheet 5;

[0049] S2. Fixation: The scraper plate 46 and the soft scraper member 47 are used as bearing points, so that the scraper rod 43 can slide upward inside the through hole 42, and the scraper plate 46 and the soft scraper member 47 are tightly pressed against the upper end surface of the processed sheet material 5 by the resilience of the third spring body, which can effectively increase the fixation of the processed sheet material 5;

[0050] S3, detection: when the drill bit moves downward, the detection rod 252 slides upward in the sliding hole 22 at a uniform speed. At the same time, the limit plate 25 drives the pressure sensor 252 upward to contact the lower end surface of the pressure rod 27. The pressure sensor 252 presses the pressure rod 28 upward in the sliding hole 22 under the uniform pressure, and presses the second spring body 26 upward. When the drill bit cannot drill, the pressure value remains unchanged or the pressure amplitude is not large, and the dwell time is 3 to 5 seconds. When the controller receives the signal, the Z-direction moving device 14 and the driving device 15 are stopped, which can automatically protect the drill bit to avoid jamming and avoid serious damage to the processed sheet material 5.

[0051] S4, iron filings collection: start the hydraulic cylinder 31 to drive the transmission plate 351 to press downward against the rack plate 352, and the rack plate 352 meshes with the gear 355 to one side, so that the gear 355 drives the rotating shaft 356 and the pressing plate 357 to rotate downward clockwise, and as the rotating shaft 356 gradually rotates, one side of the soft scraper 47 contacts the upper end surface of the processed sheet material 5, and as the rotating shaft 356 gradually rotates, one side of the soft scraper 47 gradually pushes and concentrates the iron filings generated by the processing to the middle, so that the upper end surface of the processed sheet material 5 can be fully cleaned without manual work, which can reduce workload and time and improve convenience;

[0052] S5. Assistance: Continuing with the working movement of the fourth step, the rounded corner of one side of the pressure plate 357 contacts the upper end surface of the processed sheet 5. At this time, start the Z-axis moving device 14 to move the L-shaped moving plate 151 upward. At the same time, one side of the pressure plate 357 is pressed downward, thereby pushing the processed sheet 5 and the drill bit downward. This step can be performed manually, and the power of the machine itself can be used to assist the manual work, which can save a lot of time and reduce labor.

[0053] The specific working principle of the present invention includes the following process:

[0054] First, when drilling, the processing sheet material 5 is placed on the workbench, then the Y-direction moving device 11 and the X-direction moving device 13 are started to move to the position where the hole needs to be drilled, and then the Z-direction moving device 14 is started to drive the L-shaped moving plate 151 to drive the drill bit to move downward, and then the driving device 15 is started to drive the drill bit to rotate. As the Z-direction moving device 14 gradually moves downward, the rotating drill bit gradually drills a hole on the upper end surface of the processing sheet material 5. At the same time, the soft scraper 47 first presses against the upper end surface of the processing sheet material 5 (the stretching mechanism 3 is in the original state, as shown in FIG. 1 ). Figure 5As shown), the drill bit continues to drill downward, and the soft scraper 47 gradually bends, causing the scraper 46 to contact the processing sheet 5. The drill bit continues to drill downward, so that the scraper 46 and the soft scraper 47 are subjected to force as bearing points, allowing the scraper rod 43 to slide upward inside the through hole 42 under the reverse force, and be stretched upward to the third spring body through the pressure plate 4. The scraper 46 and the soft scraper 47 are tightly pressed against the upper end surface of the processing sheet 5 by the rebound force of the third spring body 45, thereby increasing the fixing effect of the processing sheet 5.

[0055] For example, when the drill bit is drilling, due to the high hardness of the material, the drill bit itself may be severely damaged or stuck. In order to avoid this phenomenon, a pressure detection mechanism 2 is provided. When the drill bit moves downward, the detection rod 252 and the V-shaped plate 28 are first pressed against the upper end surface of the processed sheet material 5, and the drill bit performs the drilling work under the uniform movement of the L-shaped moving plate 151. Among them, the detection rod 252 and the V-shaped plate 28 are subjected to the resistance of the upper end surface of the processed sheet material 5, so that the detection rod 252 slides upward in the sliding hole 22 at a uniform speed. At the same time, the limit plate 25 slides upward inside the limit hole 22 and stretches upward to The first spring body 251, the pressure sensor 252 on its limit plate 25 contacts the lower end surface of the pressure rod 27. The pressure sensor 252 forces the pressure rod 28 to slide upward inside the sliding hole 22 under the uniform pressure, and presses the second spring body 26 upward. When the drill bit cannot be drilled again, the pressure value generated by the pressure sensor 252 remains unchanged or the pressure fluctuation is small (when this happens, it will stay for about 3 to 5 seconds and then transmit the signal to the controller). The pressure value at this time is transmitted to the controller, and the controller receives the signal to stop the Z-axis moving device 14 and the driving device 15.

[0056] When the drill bit is stuck in the processing sheet 5, the hydraulic cylinder 31 can be started to drive the telescopic rod 32 to move downward, and the transmission housing 33 is forced to press downward on the two transmission plates 351, and the transmission plates 351 are forced to press downward on the rack plate 352. The rack plate 352 is forced to slide to one side inside the transmission groove 354 through the sliding plate 353, and the rack plate 352 is meshed with the gear 355, so that the gear 355 drives the rotating shaft 356 to rotate clockwise in the rotating holes of the first support plate 3561 and the second support plate 3562, and the rotating shaft 356 drives the pressing plate 357 to rotate downward in the clockwise direction. As the rotating shaft 356 gradually rotates, the soft scraper One side of 47 abuts against the upper end surface of the processing sheet material 5 (during drilling, the soft scraper 47 has abutted against the upper end surface of the processing sheet material 5), and then during gradual rotation, one side of the soft scraper 47 gradually pushes and concentrates the iron chips generated by the processing to the middle (it can also push the iron chips separately) until the rounded corner on one side of the pressure plate 357 abuts against the upper end surface of the processing sheet material 5. At this time, start the Z-direction moving device 14 to allow the L-shaped moving plate 151 to move upward. At the same time, one side of the pressure plate 357 is pressed downward, thereby achieving the goal of pushing the processing sheet material 5 and the drill bit downward. This step can be performed manually, and the force of the machine itself can be used to assist manual work.

9. A method using the drill bit automated processing device according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, drilling: start the Y-direction moving device (11) and the X-direction moving device (13) to move to the position where the drilling is required, then start the Z-direction moving device (14) to drive the drill bit to move downward, and then start the driving device (15) to drive the drill bit to rotate, so that the rotating drill bit gradually drills a hole on the upper end surface of the processed plate (5); S2, fixation: by using the scraper (46) and the soft scraper (47) as bearing points, the scraper rod (43) can slide upward inside the through hole (42), and the rebound force of the third spring body can be used to tightly press the scraper (46) and the soft scraper 47 (47) against the upper end surface of the processed sheet material (5), which can effectively increase the fixation of the processed sheet material (5); S3, detection: when the drill bit moves downward, the detection rod (252) slides upward in the sliding hole (22) at a uniform speed. At the same time, the limit plate (25) drives the pressure sensor (252) upward to contact the lower end surface of the pressure rod (27). Under the pressure of the uniform speed, the pressure sensor (252) causes the pressure rod (28) to slide upward in the sliding hole (22) and press upward on the second spring body (26). When the drill bit cannot drill, the pressure value remains unchanged or the pressure change amplitude is not large. The dwell time is 3 to 5 seconds. When the controller receives the signal, the Z-direction moving device (14) and the driving device (15) are stopped; S4, collecting iron chips: starting the hydraulic cylinder (31) to drive the transmission plate (351) to press downward against the rack plate (352), and the rack plate (352) is meshed with the gear (355) to one side, so that the gear (355) drives the rotating shaft (356) and the pressing plate (357) to rotate downward clockwise, and as the rotating shaft (356) gradually rotates, one side of the soft scraper (47) contacts the upper end surface of the processed sheet material (5), and as the processing gradually rotates, one side of the soft scraper (47) gradually pushes the iron chips generated by the processing to the middle and collects them; S5, auxiliary: Continuing with the working movement of the fourth step, the rounded corner of one side of the pressure plate (357) contacts the upper end surface of the processing sheet (5). At this time, the Z-direction moving device (14) is started to allow the L-shaped moving plate (151) to move upward. At the same time, one side of the pressure plate (357) is pressed downward, thereby pushing the processing sheet (5) and the drill bit downward. This step can be coordinated manually.
