Description

Technical Field

[0001] This invention relates to the field of equipment for drill bit inspection, and more particularly to a multi-dimensional online inspection device for drill bit machining holes. Background Technology

[0002] Drill bits are widely used impact drilling tools in mining, tunneling, and civil engineering. They are primarily connected to the drilling rig or drill rod via a mounting structure at the tail. The machining of drill bits involves threading and tapping or creating a slot at the tail. Since the tapping accuracy and slotting clearance are highly dependent on the inner diameter of the machined hole, the machining accuracy of this hole directly determines the stability of subsequent assembly operations and the lifespan of the drill bit, ensuring connection reliability and uniform stress distribution. Therefore, before tapping or slotting, the inner diameter of the drill bit's machined hole must be rigorously inspected to ensure that its accuracy meets process requirements.

[0003] However, the current method for inspecting drill bit machining holes is still mainly manual. Operators use measuring tools to measure, read, and record each machining hole one by one to determine whether the dimensions are up to standard. Obviously, this process involves a high degree of manual intervention, requiring operators to repeatedly position and operate the drill bit, resulting in a slow inspection speed. At the same time, manual measurement is prone to subjective operational errors, leading to insufficient reliability of the inspection results. Summary of the Invention

[0010] Furthermore, the device also includes: a mounting frame, fixedly connected to the side of the testing table; and a control board, fixedly connected to the mounting frame.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example: A multi-dimensional online inspection device for drill bit machining holes, see reference. Figures 1-4The device includes: a testing table 101; a mounting ring 102 rotatably mounted on the outer ring of the top surface of the testing table 101; a drive assembly located inside the testing table 101 and connected to the mounting ring 102 for driving the mounting ring 102 to rotate around its own axis; a material cylinder 103 fixedly mounted on the mounting ring 102, with six sets of material cylinders 103 equidistantly arranged along the circumference of the mounting ring 102 for holding the drill bit 001; a mounting frame 104 fixedly mounted on the top center of the testing table 101; a control console 105 fixedly mounted on the mounting frame 104 for operating the device; in this embodiment, the control console 105 integrates a Siemens S7-1200 PLC and a data acquisition card; and an electric push rod 106 fixedly mounted on the mounting frame 104, whose control module is signal-connected to the control console 105; in this embodiment, a Thomson EL100 push rod is used. An ectrakHD electric actuator is used to ensure the smoothness and accuracy of the lifting and lowering of the detection unit; a mounting sleeve 107 is fixedly installed on the end of the electric actuator 106, and is driven to lift and move by the electric actuator 106; a rotating shaft 108 is rotatably installed on the lower end of the mounting sleeve 107; a first motor 109 is fixedly installed inside the mounting sleeve 107, and its output end is coaxially fixedly connected to the rotating shaft 108 to drive the rotating shaft 108 to rotate around its own axis. The control module of the first motor 109 is signal-connected to the control console 105. In this embodiment, a Panasonic MINASA6 series servo motor is used, which is connected to the rotating shaft 108 through a precision reducer; a detection unit is located at the lower end of the rotating shaft 108 and is used to detect the inner diameter of the drill bit 001. The detection unit is located directly above the moving trajectory line of the barrel 103.

[0029] See Figure 2 , Figure 4 , Figure 5 and Figure 10 The detection unit includes: a hydraulic actuator 201, fixedly mounted on the lower end of the rotating shaft 108, whose control module is signal-connected to the control console 105; a mounting shaft 202, slidably mounted on the hydraulic actuator 201 in the horizontal direction, with four sets of mounting shafts 202 evenly arranged around the circumference of the hydraulic actuator 201, and capable of controlling all mounting shafts 202 to move synchronously along their own axes. In this embodiment, a Bosch Rexroth electro-hydraulic servo cylinder is used, which can precisely control the extension displacement according to the control console command; and a top shaft 203, slidably mounted on the mounting shaft 202. The outer end; a first return spring 204, fixedly installed between the mounting shaft 202 and the top shaft 203; a pressure sensing module 205, fixedly installed on the mounting shaft 202, the end of the first return spring 204 is in contact with the sensing area of ​​the pressure sensing module 205, the pressure sensing module 205 is signal connected to the control console 105, and a miniature pressure sensor from MEGGITT is used in this embodiment; a ball bearing 206, embedded in the outer end of the top shaft 203, is used to contact the inner wall of the machining hole of the drill bit 001.

[0030] The electric push rod 106 of this device is activated, driving the mounting sleeve 107 and the detection unit below it to descend as a whole, sending the detection unit into the machining hole of the drill bit 001; subsequently, the hydraulic device 201 is activated, controlling each mounting shaft 202 to extend outward synchronously, so that the circumference radius of the outermost end point of the ball 206 on the top shaft 203 is adjusted to the theoretical inner radius of the machining hole of the drill bit 001. In the initial state of the mounting shaft 202, this circumference radius is a fixed value. In actual operation, it is only necessary to control the extension distance of the mounting shaft 202 to be the difference between the theoretical inner radius of the drill bit 001 and this circumference radius; in the above process, if the size of the machining hole of the drill bit 001 is accurate, the ball 206 will just contact the inner wall of the hole. At this time, the first return spring 204 is in a naturally extended state without compression deformation.

[0031] Subsequently, the hydraulic actuator 201 continues to push the mounting shaft 202 outward by a preset fixed stroke, causing the first return spring 204 to compress. If the machining hole size is accurate, the pressure feedback values ​​measured by the pressure sensing modules 205 on each mounting shaft 202 should be consistent. If a pressure sensing module 205 does not receive pressure feedback or receives feedback with a delay, it indicates that there is a deviation in the inner diameter at that location. Next, the first motor 109 starts, driving the rotating shaft 108 and its detection unit to rotate as a whole, with the ball bearing 206 rolling along the inner wall of the machining hole. If the feedback values ​​of each pressure sensing module 205 remain constant during rotation, it indicates that the inner diameter of the machining hole is uniform and the size is accurate. If the values ​​change, it indicates that the drill bit 001 has roundness or coaxiality defects. After the inspection is completed, the first motor 109 is turned off, the hydraulic actuator 201 controls the mounting shaft 202 and the top shaft 203 to retract, and the first return spring 204 automatically returns the top shaft 203 to its initial position.

[0032] The drive assembly drives the mounting ring 102 to rotate, sequentially conveying each material cylinder 103 and its loaded drill bits 001 to the area directly below the testing unit for inspection. During this process, the operator can simultaneously unload the inspected drill bits 001 and load the drill bits 001 to be inspected, thereby shortening the operation cycle and improving testing efficiency.

[0033] This equipment uses a hydraulic actuator 201 to drive multiple mounting shafts 202 to extend synchronously, and a pressure sensing module 205 provides real-time feedback of contact pressure, enabling quantitative detection of the inner diameter. Combined with a first motor 109 driving ball bearings 206 to roll along the hole wall, it can continuously monitor pressure changes and accurately identify uneven inner diameter and roundness errors. Simultaneously, the drive assembly drives the mounting ring 102 for automatic cyclic feeding, supporting parallel loading and unloading operations, significantly improving detection efficiency and automation. Therefore, this equipment solves the problems of low accuracy, slow speed, and easy omissions in manual inspection.

[0034] See Figure 2 and Figure 6The drive components include: a second motor 301, which is fixedly installed inside the testing table 101, and its control module is connected to the control console 105 via signal. In this embodiment, a Panasonic MINASA6 series servo motor is used; a drive gear 302, which is rotatably installed inside the testing table 101 and is coaxially fixedly connected to the output end of the second motor 301; a driven gear 303, which is rotatably installed inside the testing table 101, and three sets of driven gears 303 are evenly arranged circumferentially inside the testing table 101, all of which mesh with the drive gear 302; and a gear ring 304, which is fixedly installed on the inner ring of the mounting ring 102, and all of which mesh with the gear ring 304.

[0035] During operation, the second motor 301 starts, driving the drive gear 302 to rotate. The drive gear 302 drives the three sets of driven gears 303 meshing with it to rotate synchronously. The driven gears 303 then drive the gear ring 304 and the mounting ring 102 fixed to it to rotate smoothly. Therefore, through the three-stage transmission structure consisting of the drive gear 302, driven gears 303, and gear ring 304, this equipment can ensure uniform power transmission, avoid damage to components due to excessive local torque, and thus ensure the long-term normal operation of this equipment.

[0036] See Figure 1 , Figure 2 , Figure 7 and Figure 8 The equipment also includes: a fixing component, which is located in each material cylinder 103 and is used to fix the drill bit 001 in the center; a fixing frame 401, which is fixedly installed on the side of the testing table 101; and a control board 402, which is detachably fixedly installed on the fixing frame 401. The fixing frame 401 is located below the mounting ring 102 and its position corresponds to the setting of the testing unit. Both ends of the control board 402 are provided with inclined structures. Each material cylinder 103 has a hydraulic chamber 403 inside its side wall, and the hydraulic chamber 403 is filled with hydraulic fluid. Each set of fixing components includes: a fixing shaft 404, which is slidably installed on the side wall of each material cylinder 103, with its outer end located inside the material cylinder 103 and its inner end located in the hydraulic chamber 403. The fixing shaft 404 is evenly arranged along the inner circumference of the material cylinder 103 to center and fix the drill bit 001 by moving synchronously towards the center; and a piston plate 405, which is slidably installed on each material cylinder 103, with its outer end located inside the hydraulic chamber 403. Below the cylinder 103, its inner end is located in the hydraulic chamber 403, and it changes the pressure of the hydraulic fluid in the hydraulic chamber 403 by displacement; the connecting plate 406 is fixedly installed at the bottom of the outer end of all piston plates 405; the second return spring 407 is fixedly installed between the cylinder 103 and the connecting plate 406; the top column 408 is fixedly installed at the bottom of the connecting plate 406, and can contact the control plate 402 and cooperate with the inclined structure of the control plate 402 during the movement of the cylinder 103.

[0037] During the process of the installation ring 102 driving the barrel 103 to move, when the barrel 103 enters the detection work area of ​​the detection unit and moves to the corresponding position of the control plate 402, the top column 408 at the bottom of the barrel 103 contacts and engages with the control plate 402 through the inclined structure; as the barrel 103 continues to move, the top column 408 is squeezed upward by the inclined surface and moves upward, driving the piston plate 405 to slide into the hydraulic chamber 403, thereby squeezing the hydraulic fluid, so that all the fixed shafts 404 slide synchronously towards the center line of the barrel 103, thereby centering and fixing the drill bit 001, ensuring that the subsequent detection unit can stably detect the drill bit 001; at the same time, during this process, the connecting plate 406 moves closer to the barrel 103, and the second return spring 407 is compressed. After the drill bit 001 completes the inspection and is carried away from the inspection area by the material cylinder 103, the top column 408 gradually separates from the control plate 402, the second return spring 407 resets, pushing the piston plate 405 and connecting plate 406 back to their original positions, reducing the pressure in the hydraulic chamber 403, and the fixed shaft 404 automatically releases the drill bit 001. Thus, the fixing assembly automatically fixes and unlocks the drill bit 001, requiring only the operator to perform loading and unloading actions, significantly improving the ease of operation of this equipment. When it is necessary to inspect drill bits 001 of different sizes, only the control plate 402 of the corresponding height needs to be replaced, effectively expanding the applicability of this equipment.

[0038] See Figure 1 , Figure 2 and Figure 9 The device also includes: a first camera module 501, fixedly mounted on the mounting frame 104, with two sets arranged on both sides of the detection station of the detection unit, used to record the detection data of the drill bit 001. The first camera module 501 is connected to the control console 105 via signal. An LED ring 502 is fixedly mounted on the top surface of the material cylinder 103, and its control module is connected to the control console 105 via signal. A second camera module 503 is fixedly mounted on the mounting frame 104, used for visual detection of whether the drill bit 001 exists in the material cylinder 103. The second camera module 503 is connected to the control console 105 via signal. In this embodiment, both the first camera module 501 and the second camera module 503 use Hikvision MV-CA016-10GM industrial cameras.

[0039] During the inspection process, the two sets of first recording modules 501 record the inspection data and corresponding results of each drill bit 001 to enable product quality traceability. When the inspection unit detects a defective drill bit 001, it sends a feedback signal to the control console 105, which then controls the corresponding light ring 502 on the material cylinder 103 to illuminate, prompting the operator to handle the problematic drill bit 001 separately. The second recording module 503 is used to detect whether the drill bit 001 has been removed. When it detects that the material cylinder 103 is empty, the control console 105 automatically controls the light ring 502 to turn off. The above structural design effectively improves the ease of operation of this equipment and facilitates on-site operation management.
