Description

Technical Field

[0001] This invention relates to a drilling device, and more specifically, to a multi-station drilling processing device and its control method. Background Technology

[0002] In the production and processing of various workpieces, it is usually necessary to drill holes on the surface of the finished workpiece so that the finished workpiece can be positioned and installed through the machined holes. The drilling method usually involves clamping the finished workpiece on a drilling machine and drilling the workpiece with the drill bit of the drilling machine. In actual processing, based on production needs, the workpiece needs multiple holes. However, due to the fixed clamping position and drill bit position of the drilling machine, a single drilling machine can only perform drilling processing on a single workpiece at a single position. Therefore, if it is necessary to perform drilling processing on a workpiece with multiple holes, it is necessary to frequently switch the drill bit position of the drilling machine, or to set up multiple drilling machines to process the workpiece. The above solutions have low processing efficiency, require frequent manual adjustment of drill bit position or clamping and unloading, and result in a heavy workload for workers, making it difficult to adapt to the mass production of multiple holes.

[0003] Currently, there is a workpiece drilling equipment on the market that can perform multiple drilling operations at different positions in a single clamping by clamping the workpiece once and moving it between different drilling devices, which greatly improves the efficiency of drilling. The operator only needs to perform loading and unloading operations, reducing the labor intensity of the operator. However, the above drilling process can only process horizontally set workpieces. If the processing end face of the workpiece is tilted, it is difficult to process and the operator needs to intervene and perform manual processing. The overall operation is difficult. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multi-station drilling equipment and its control method that has a high degree of automation, can process multiple holes simultaneously, and can perform inclined hole processing on workpieces with a certain angle.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-station drilling processing equipment, including a processing chassis, a rotating shaft on the processing chassis, a plurality of processing devices evenly arranged along the circumference of the processing chassis, a locking device matching each processing device on the processing chassis, the locking device being configured to lock the workpiece disposed therein and to perform drilling processing through the processing device, and an indexing plate inside the processing chassis, the rotation angle of the processing chassis being limited by the indexing plate to achieve processing station switching.

[0006] The present invention is further configured such that: the processing device includes a slanted hole processing component and an internal hole processing component, the slanted hole processing component includes drill rods symmetrically arranged at the upper and lower ends of the processing chassis with the horizontal plane of the processing chassis as a reference, and a drive cylinder arranged on each drill rod, the drive cylinder also being provided with an angle adjustment component.

[0007] The present invention is further configured such that: the locking device includes a mounting component disposed on the processing chassis, a material placement groove disposed within the mounting component, and an abutting cylinder disposed within the mounting component; the workpiece is inserted into the material placement groove and fixed by the abutting cylinder; each of the abutting cylinders has an abutting portion that can extend into the material placement groove and a driving portion disposed outside the mounting component.

[0008] Preferably, the mounting component is further provided with a processing opening, which is configured to form a straight line with the workpiece to be drilled position and the drill rod after the workpiece is inserted into the material placement groove and fixed. The mounting component is also provided with a clamping groove at a position away from the workpiece insertion end. The clamping groove is provided on the surface of the mounting component and extends at least to the material placement groove position in the mounting groove. The top of the clamping groove is also provided with a pressing cylinder. The top of the pressing cylinder is provided with a pressing plate that matches the width of the clamping groove and a stop block provided in the pressing plate for extending into the material placement groove.

[0009] Preferably, the mounting assembly is further provided with a snap-fit ​​cylinder on the side near the workpiece insertion end. The snap-fit ​​cylinder is rotatably provided with a snap-fit ​​baffle. A locking element is also provided between the snap-fit ​​baffle and the snap-fit ​​cylinder. The snap-fit ​​baffle is configured to rotate to a position facing away from the workpiece when the workpiece is inserted, and to rotate to a position facing the workpiece after the workpiece is inserted to abut against the workpiece.

[0010] Preferably, the angle adjustment assembly includes a cylinder mounting plate disposed between the drive cylinders, and a rotating bearing is provided in the middle of the cylinder mounting plate. The rotating bearing is configured to adjust the tilt angle of the cylinder mounting plate so that the drill rod connecting line disposed opposite to the hole to be processed remains parallel.

[0011] This application also discloses a control method for a multi-station drilling processing equipment, including the following steps: S1, based on the number and location of the workpiece to be drilled, the processing device in the processing equipment is adjusted in advance to form a station for drilling processing at various positions of the workpiece. S2. After the processing device is adjusted, adjust the snap-fit ​​baffle so that the snap-fit ​​baffle does not block the insertion path of the workpiece. At the same time, the abutment cylinder and the pressing cylinder move away from the material placement groove so that the workpiece is not blocked during the insertion of the material placement groove. S3. After the workpiece is inserted, the lower cylinder drives the lower platen to move towards the clamping groove and the material placement groove. During the movement, the pressure on the abutment block on the lower platen is detected. The detection value is P1. If P1 > 0, it is determined that the abutment block is pressing the workpiece tightly, and the process jumps to S4 for horizontal locking. Otherwise, it is determined that the current workpiece has not been inserted completely or the size of the material placement groove is too large. The locking device is adjusted, and the detection is repeated after the adjustment is completed. S4. After the pressing cylinder has finished abutting the workpiece, the clamping baffle is adjusted so that the clamping baffle rotates to the position where the workpiece is inserted into the material slot. At the same time, the clamping cylinder drives the clamping baffle to move towards the workpiece and abut against it. S5. After the workpiece is installed, the machining chassis rotates at a fixed angle via the rotating shaft and indexing plate, so that the mounting component with the workpiece to be processed moves to the position of the next sequential inclined hole machining component. S6. At the current workpiece position that needs to be processed, the opening angle of the workpiece to be processed is detected. The detection value is the offset angle of the opening to be processed relative to the central axis of the processing chassis after connecting the midpoint of the opening to be processed. S7. The transmission bearing adjusts the angle of the cylinder mounting plate so that after adjustment, the tilt angle of the drill rod on the cylinder mounting plate matches the opening tilt angle of the workpiece to be processed. S8. The drive cylinder drives the drill rod to move closer to the workpiece, thereby forming a slanted hole on the workpiece surface at a corresponding angle. S9. After the oblique hole is machined, the machining base rotates at a fixed angle through the rotating shaft and the indexing plate, so that the mounting component moves to the position of the next sequential inner hole machining component. S10. The internal hole machining assembly adjusts the position of the drill rod so that the position of the drill rod and the machining hole are on the same vertical plane. After the position of the drill rod is adjusted, the drill rod is driven to drill the workpiece. S11. After drilling is completed, the machining chassis rotates again, causing the mounting assembly to rotate to the starting position for mounting the workpiece. The machined workpiece is then removed and the workpiece to be machined is reinstalled.

[0012] Preferably, the oblique hole angle detection method in step S6 includes the following steps: S61, the locking device is provided with a plurality of tilt detection components, including a plurality of position sensors arranged in sequence in the horizontal direction, the height of the position sensors being matched with the height of both ends of the workpiece respectively; S62. The position sensors at both ends detect the corresponding positions of the two ends of the workpiece within the position sensors, and record the positions of the two ends of the workpiece after tilting and shifting. S63. The workpiece offset angle is detected by taking the vertical line at the midpoint of the virtual connection line corresponding to both ends of the workpiece as a reference, and the corresponding position sensor as the reference for offset detection. S64. Detect the offset position of the workpiece relative to the reference position, and calculate the offset angle and offset direction of the inclined hole on the workpiece based on the offset position; S65. Based on the offset angle and offset direction of the inclined hole, adjust the rotation of the cylinder mounting plate so that the tilt angle and tilt direction of the cylinder mounting plate match the workpiece.

[0013] Preferably, the starting position for installing the workpiece is configured as a loading station, which is configured to unload the finished workpiece and place the workpiece to be processed when the processing chassis rotates.

[0014] By adopting the above technical solution, the following beneficial effects are achieved: 1. This application achieves precise switching of processing stations by using a processing chassis in conjunction with a rotating shaft and an indexing plate. Several processing devices are evenly arranged along the circumference of the processing chassis, allowing the workpiece to sequentially complete the continuous processing of multiple holes through different processing stations after a single clamping. Simultaneously, by setting a slanted hole processing component as a station for processing slanted holes and an internal hole processing component for processing the workpiece positioned inside the clamping structure, the slanted hole processing component is equipped with an angle adjustment component, enabling the equipment to process the end face of a horizontally positioned workpiece. It also allows for adaptive adjustment of the drilling angle of the drill rod according to the actual inclination angle of the slanted hole to be processed on the workpiece. This design achieves automated machining of inclined holes on inclined end faces. Furthermore, the locking device uses a material placement groove, abutment cylinder, pressing cylinder, and clamping cylinder to lock the workpiece in multiple directions, ensuring that the workpiece maintains a stable machining position even under the force of the drill rod in different directions during machining. This further guarantees the accuracy and reliability of the drilling process. In the control method of this application, automated control of inclined holes at different angles is achieved through indexing, angle detection of the inclined hole, and adaptive matching of the drill rod angle. This significantly improves the production efficiency of machining multi-position irregular holes, eliminating the need for precise adjustments to angles and workpiece positions by operators, thus reducing the labor intensity and technical threshold for workers.

[0015] 2. Furthermore, the inclined hole machining assembly of this application symmetrically arranges drill rods at the upper and lower ends of the machining chassis with the horizontal plane of the machining chassis as the reference, and a drive cylinder is arranged on each drill rod. The drive cylinder is equipped with an angle adjustment assembly, which includes a cylinder mounting plate arranged between the relative drive cylinders and a rotating bearing arranged in the middle of the cylinder mounting plate. During the machining process, the control system first detects the offset angle of the midpoint connecting line of the hole to be machined relative to the central axis of the machining chassis. Then, the tilt angle of the cylinder mounting plate is precisely adjusted by the rotating bearing, so that after the adjustment, the connecting line of the drill rods arranged relative to each other is parallel to the connecting line of the hole to be machined. After the angle adjustment is completed, the drive cylinder can drive the drill rod to feed along the adjusted angle direction, so that the inclined hole can be formed on the surface of the workpiece at an angle that perfectly matches the tilt angle of the inclined hole to be machined. This angle adjustment matching mechanism can effectively avoid hole position deviation caused by the mismatch between the machining angle and the tilt angle of the workpiece, and greatly improve the yield and machining quality of the inclined hole machining.

[0016] 3. Simultaneously, this application utilizes a multi-locking device comprised of a material placement groove, an abutment cylinder, a pressing cylinder, and a clamping cylinder, along with a corresponding pressure feedback detection mechanism, to achieve reliable locking of the workpiece and automatic verification of its clamping status. This effectively ensures the positional stability of the workpiece during multi-station continuous processing. Specifically, the locking device includes a mounting assembly mounted on the processing chassis, a material placement groove within the mounting assembly, and an abutment cylinder within the mounting assembly. After the workpiece is inserted into the material placement groove, it is initially fixed by the abutment cylinder. The mounting assembly also features a processing opening and a clamping groove. A pressing cylinder is installed at the top of the clamping groove. A pressing plate matching the width of the clamping groove is installed at the top of the pressing cylinder, along with a stop block extending into the material placement groove. The pressing cylinder drives the pressing plate to move closer to the clamping groove and the material placement groove, achieving secondary clamping of the workpiece. A snap-fit ​​cylinder is also installed on the side of the mounting assembly near the workpiece insertion end. A snap-fit ​​baffle is rotatably mounted on the snap-fit ​​cylinder, and a locking element is provided between the snap-fit ​​baffle and the snap-fit ​​cylinder. After the workpiece is inserted, the snap-fit ​​baffle rotates to face the workpiece and abuts against it, achieving tertiary locking of the workpiece. At the control method level, step S3 detects the pressure value P1 on the stop block on the pressing plate and determines whether P1 > 0, achieving quantitative detection and automatic verification of the workpiece clamping state. If the detected value is abnormal, the locking device is automatically adjusted and re-detected, ensuring that each workpiece is reliably locked before entering the processing station, effectively avoiding processing accidents and product scrap caused by improper clamping.

[0017] 4. Furthermore, during actual processing, this application precisely controls the rotation angle of the processing chassis via an indexing plate, ensuring that the processing device matches the locking device after each rotation operation. This enables precise completion of the machining of inclined and straight holes, forming an efficient, continuous, and automated multi-hole machining process. This significantly shortens the process interval and allows for unified management through a single operating station. The overall machining process is as follows: The processing chassis is equipped with an indexing plate. The rotation angle of the processing chassis is limited by the indexing plate to achieve precise switching between machining stations. This allows the mounting assembly with the workpiece to sequentially pass through the inclined hole machining station and the inner hole machining station, completing the inclined hole machining and straight hole machining respectively. After the inclined hole machining is completed, the processing chassis rotates to a fixed angle via the rotating shaft and the indexing plate, moving the mounting assembly to the next sequential inner hole machining station. The hole machining component positions itself so that the drill rod is aligned with the machining hole on the same vertical plane, then drives the drill rod to drill the workpiece. After all machining operations are completed, the machining chassis rotates again to return the mounting components to the initial loading position. The operator can unload the finished workpiece and load the workpiece to be machined from the same position. Furthermore, the number of machining devices can be dynamically adjusted based on the number and position of the holes to be machined, achieving complete machining after a single loading. The above-mentioned workstation layout and process design enable the equipment to complete multi-position sequential machining of inclined and straight holes under a single clamping condition. At the same time, only one operator is needed to complete the loading and unloading operations at the same workstation, which greatly shortens the process interval time, reduces the manpower configuration requirements, and realizes efficient, continuous, automated mass production.

After the oblique hole is machined, the machining base rotates at a fixed angle through the rotating shaft and the indexing plate, so that the mounting component moves to the position of the next sequential inner hole machining component. S10. The internal hole machining assembly adjusts the position of the drill rod so that the position of the drill rod and the machining hole are on the same vertical plane.

After drilling is completed, the machining chassis rotates again, causing the mounting assembly to rotate to the starting position for mounting the workpiece. The machined workpiece is then removed and the workpiece to be machined is reinstalled.

[0029] Preferably, the oblique hole angle detection method in step S6 includes the following steps: S61, the locking device is provided with a plurality of tilt detection components, including a plurality of position sensors arranged in sequence in the horizontal direction, the height of the position sensors being matched with the height of both ends of the workpiece respectively; S62.

[0031] This application achieves precise switching of machining stations through a machining chassis 1, a rotating shaft 11, and an indexing plate. Several machining devices 2 are evenly arranged along the circumference of the machining chassis 1, allowing the workpiece to sequentially pass through different machining stations after a single clamping to complete continuous machining of multiple holes. Simultaneously, by setting a slanted hole machining component 21 as a station for machining slanted holes and an inner hole machining component 22 within the machining device 2 to machine the workpiece positioned inside the clamping structure, the slanted hole machining component 21 is equipped with an angle adjustment component 25.

Then, the tilt angle of the cylinder mounting plate 251 is precisely adjusted by rotating shaft 11, so that the connecting line of the drill rod 23 and the connecting line of the hole to be processed are parallel after the adjustment. After the angle adjustment is completed, the drive cylinder 24 can drive the drill rod 23 to feed along the adjusted angle direction, so that the inclined hole can be formed on the workpiece surface at an angle that is completely matched with the tilt angle of the inclined hole to be processed. This angle adjustment and matching mechanism can effectively avoid hole position deviation caused by mismatch between the processing angle and the workpiece tilt angle, and greatly improve the yield and processing quality of the inclined hole processing.

At the control method level, in step S3, the pressure value P1 of the block 38 on the lower pressure plate 37 is detected and it is determined whether P1 > 0, thereby realizing the quantitative detection and automatic verification of the workpiece clamping state. If the detected value is abnormal, the locking device 3 is automatically adjusted and re-detected, thus ensuring that each workpiece is in a reliable locking state before entering the processing station, effectively avoiding processing accidents and product scrap caused by improper clamping.

[0034] Furthermore, during actual processing, this application precisely controls the rotation angle of the processing chassis 1 using an indexing plate, ensuring that the processing device 2 matches the locking device 3 after each rotation operation. This enables precise completion of the machining of inclined and straight holes, forming an efficient, continuous, and automated multi-hole machining process.

The machining component 22 adjusts the position of the drill rod 23 so that it is on the same vertical plane as the machining hole, and then drives the drill rod 23 to drill the workpiece. After all machining processes are completed, the machining chassis 1 rotates again to return the mounting component 31 to the initial loading position. The operator can unload the finished workpiece and load the workpiece to be processed in the same position. The number of machining devices 2 can be dynamically adjusted based on the number and position of the holes to be processed, so as to achieve complete processing after a single loading. The above-mentioned station layout and process design enable the equipment to complete multi-position sequential processing of inclined holes and straight holes under a single clamping condition. At the same time, only one operator is needed to complete the loading and unloading operations in the same station, which greatly shortens the process interval time, reduces the manpower configuration requirements, and realizes efficient and continuous automated batch production.
