Description

Technical Field

[0001] This invention relates to a drilling and cutting composite equipment, specifically an intelligent drilling and cutting equipment based on automotive windshield grid processing. Background Technology

[0002] The windshield grille is a core functional and aesthetic component of the car's front fascia assembly. It primarily serves for air intake and heat dissipation, front fascia decoration, and protection. It is typically made of thin-walled engineering plastics or aluminum alloys, featuring an irregularly shaped curved surface with densely packed grille cutouts and multiple mounting points. Post-processing involves several steps, including drilling mounting holes and trimming the inner and outer contours. As an aesthetic component, it demands high standards for surface quality, hole precision, and dimensional tolerances.

[0003] Referring to the heat sink fin drilling and cutting equipment disclosed in patent application CN116604347A, by sequentially arranging drilling and cutting devices inside the machine casing, the entire heat sink fin is fed into the machine casing and passes through the drilling and cutting stations in sequence, forming a processing line, thereby shortening the processing cycle of the heat sink fin and improving the processing efficiency of the heat sink fin; by setting a partition in the blanking frame, the blanking frame can be divided into several storage areas for storing heat sink fins, thereby making full use of the space inside the blanking frame and facilitating the neat placement of the heat sink fins. The drilling and cutting equipment described above has the following drawbacks in practical use: 1) Existing equipment clamping mechanisms mostly adopt rigid single-point pressure block structures. The contact area of ​​a single clamping point is small and stress is concentrated. For the curved outer wall of the car windshield, it cannot adapt to the irregular contour to form a uniform clamping. It is very easy to cause indentation, dents or even cracks in thin-walled areas, making it difficult to meet the quality standards of appearance parts. Moreover, the contours of windshields vary greatly between different car models. Changeover production requires the customization and replacement of a whole set of special fixtures, resulting in high tooling costs, long debugging cycles, and difficulty in ensuring clamping efficiency and clamping consistency in batch processing.

[0004] 2) Existing equipment mainly adopts a simple structure for waste chip collection, which is an open bottom chute. The drill chips and cutting chips generated during processing tend to accumulate in the gaps between the workpiece support table and the fixture. This not only easily scratches the appearance of the workpiece, but also requires frequent machine stops for manual cleaning of the gaps in the equipment table, interrupting the continuous processing flow and increasing the difficulty of waste chip cleaning.

[0005] Therefore, this invention proposes an intelligent drilling and cutting device based on automotive windshield grid processing to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an intelligent drilling and cutting device based on automotive windshield grille processing. It solves the problems of existing equipment's clamping mechanism being a rigid single-point pressure block, which has a small contact area, stress concentration, and difficulty in adapting to the curved surface of automotive windshield grilles. Thin-walled parts are prone to indentation and cracking, failing to meet the quality requirements of appearance parts. Moreover, drilling and cutting waste is only collected by the bottom open groove, and the debris easily accumulates in the gaps of the table, scratching the workpiece. Frequent and long-term machine shutdowns for manual cleaning are required, increasing the difficulty of waste cleaning.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an intelligent drilling and cutting device based on automotive windshield grille processing, comprising a gantry frame, and further comprising: The base, located inside the gantry and extending through the interior and outwards at both ends, serves as an operating platform for processing automotive windshield grilles. A horizontal linear module is fixedly installed on the front of the gantry, and a vertical linear module is also fixedly installed on the moving end of the horizontal linear module. The moving end of the vertical linear module is fixedly installed with a tool for drilling and cutting the windshield grille of the car. The drilling mechanism is controlled to perform drilling and cutting operations in the horizontal and vertical directions through the cooperation of the horizontal linear module and the vertical linear module. The automotive windshield grille positioning mechanism is movably mounted on the top of the base for clamping the automotive windshield grille to be processed, thereby stabilizing the position of the automotive windshield grille. The automotive windshield grille positioning mechanism can simulate and conform to the irregular outer wall shape of the automotive windshield grille, forming a multi-point clamping effect at a single clamping point to disperse the stress at the clamping point. It can also automatically collect drilling and cutting waste after completing a single operation, avoiding the impact of waste on subsequent operations. The control box is fixedly mounted on the side wall of the base and is used to control the operation of all electrical equipment.

[0008] Furthermore, long racks are fixedly installed on both sides of the outer wall of the base to cooperate with the car front windshield grille positioning mechanism to reciprocate on the top of the base, so as to cooperate with the horizontal linear module and the vertical linear module to perform drilling and cutting operations on multiple positions of the car front windshield grille surface.

[0009] Furthermore, the automotive front grille positioning mechanism includes a support seat slidably disposed on the top of the base. A first servo motor is fixedly disposed at a relative position on each of the two bottom sides of the support seat. A drive gear is fixedly disposed on the output shaft of each of the two first servo motors. The two drive gears are respectively meshed with long racks at corresponding positions. The interior of the support seat is a hollow structure. An inverted V-shaped drilling waste guide plate is fixedly disposed in the middle of the hollow structure. The top of the inverted V-shaped drilling waste guide plate is high in the middle and low on both sides. Waste collection grooves are opened on both sides of the interior of the support seat. The height of the two waste collection grooves is much lower than the lowest point of the surface of the inverted V-shaped drilling waste guide plate.

[0010] Furthermore, multiple metal vibrating plates are evenly fixedly installed on the top of the inverted V-shaped drilling waste guide plate. Vibration is generated by moving the metal vibrating plates to slide the waste chips falling on the top of the inverted V-shaped drilling waste guide plate into the waste chip collection grooves on both sides. A scraper is slidably installed at one end of the inside of the waste chip collection groove. A pull rod is also fixedly installed on the side wall of the scraper. The pull rod slides through the bearing seat and is fixedly installed with a pull ring. A waste chip drop outlet is opened on the bottom of the waste chip collection groove away from the scraper. A chip discharge pipe is fixedly installed at the bottom of the waste chip drop outlet.

[0011] Furthermore, a waste transfer mechanism is also provided above the cavity structure at the top of the support base. The waste transfer mechanism includes transmission rollers rotatably disposed on both sides inside the cavity structure. Toothed rings are fixedly sleeved on both sides of the outer wall of each transmission roller. Toothed belts are sleeved on both sides of the outer wall of two adjacent toothed rings. Multiple trays are uniformly fixed on the outer wall of two adjacent toothed belts. The top of each tray is recessed inward to form a waste storage groove. A second servo motor is fixedly disposed on the side wall of the support base. The output shaft of the second servo motor rotates through the support base and is connected to one of the transmission rollers. The toothed belts drive the multiple trays to move synchronously, dumping the waste in the waste storage groove of the trays. At the same time, the trays actuate the metal vibrating plate to generate vibration.

[0012] Furthermore, the top of the waste transfer mechanism is also provided with a positioning execution component for contour clamping and positioning the windshield grille of a car. The positioning execution component includes a base plate, and a plurality of windshield grille brackets for lifting the windshield grille from multiple points at the bottom are uniformly fixed on the top of the base plate. The top of the base plate is also provided with a plurality of contour clamping units that apply clamping force to the top of the windshield grille. A support plate is fixedly provided on the inner wall of the bearing seat and between the two transmission rollers for lifting up the plurality of trays that are in contact with the bottom of the positioning execution component.

[0013] Furthermore, the contour clamping unit includes a cylinder fixedly mounted on the top of the substrate. A clamping arm is fixedly sleeved on the output of the cylinder. A mounting base is also fixedly mounted on the bottom of the clamping arm. A plurality of clamping posts are evenly arranged on the top of the mounting base. The bottom ends of the plurality of clamping posts slide through a limiting plate and are fixedly mounted with rubber clamping heads. A limiting plate is fixedly mounted on the top end of the clamping posts. Rubber clamping heads are slidably sleeved on the outer wall of the clamping posts and located between the rubber clamping heads and the mounting base. The clamping posts and the mounting base are locked in position by fastening bolts.

[0014] Furthermore, the drilling mechanism includes an integrated mounting base, a drilling spindle unit, and a cutting execution unit. The drilling spindle unit and the cutting execution unit are fixed side by side on the integrated mounting base, which is fixedly installed on the moving end of the longitudinal linear module. The drilling spindle unit is used to perform drilling operations on the windshield grille of an automobile, and the cutting execution unit is used to perform contour cutting operations on the windshield grille of an automobile.

[0015] Furthermore, at least two parallel guide rails are fixedly provided on the top of the base along its own length direction, and a matching sliding block is fixedly provided on the bottom of the support seat corresponding to the position of the guide rails. The support seat realizes reciprocating movement on the top of the base through the sliding cooperation of the sliding block and the guide rails. The guide rails are arranged in the inner area of ​​the two long racks.

[0016] Furthermore, each of the aforementioned car windshield grille brackets is fixedly provided with a contoured support pad on its top. The top contour of the contoured support pad is adapted to the shape of the bottom outer wall of the corresponding support position of the car windshield grille, in order to increase the support contact area and disperse the local stress at the support point of the car windshield grille.

[0017] This invention provides an intelligent drilling and cutting device for processing automotive windshield grilles. Compared with existing technologies, it has the following advantages: 1. An intelligent drilling and cutting device for automotive windshield grid processing. Addressing the characteristics of the irregular curved surface and thin-walled, easily deformable nature of automotive windshield grids, the device utilizes a contour-following clamping unit in conjunction with a windshield grid bracket to achieve multi-point flexible clamping with upper and lower clamping. The contour-following support pad of the bottom bracket perfectly conforms to the bottom contour of the workpiece, dispersing lifting stress through surface contact. Multiple independently sliding clamping columns at the top, combined with rubber clamping heads, adapt to the irregular curved surface of the workpiece top, forming multi-point contact at a single clamping point. This significantly reduces compressive stress per unit area, fundamentally avoiding indentations, dents, and deformation problems during the clamping process of thin-walled grids, ensuring the appearance and structural accuracy of the workpiece.

[0018] It also supports the clamping mode of "simulation contouring - parameter memory - batch reuse": new model workpieces only need to be contoured and adjusted once. After locking the position of the clamping column by tightening the bolts, the control box records the downward stroke of the cylinder. Workpieces in the same batch can be clamped with one click by directly calling the parameters, which not only ensures the consistency of clamping, but also greatly improves the clamping efficiency of batch processing.

[0019] 2. An intelligent drilling and cutting equipment based on automotive windshield grid processing, which integrates a full-chain waste chip treatment system to realize the automatic transfer, guiding collection and centralized discharge of processing waste chips, solving the problems of waste chip accumulation affecting processing accuracy and frequent manual cleaning in existing equipment.

[0020] During processing, waste chips fall directly into the waste chip storage tank of the pallet through the cutouts in the substrate. After each processing cycle, routine chip cleaning can be performed: with the positioning actuator component still in place, the second servo motor drives the transmission roller to deflect at a set angle, causing the pallets on both sides to tilt and dump the waste chips. With the vibration assistance of the metal vibrating plate, the waste chips are guided into the waste chip collection tank through the inverted V-shaped drilled waste chip guide plate. Daily chip cleaning can be completed without stopping the machine, ensuring the cleanliness of the worktable during continuous processing and shortening downtime. Thorough chip cleaning can be performed during regular maintenance: after disassembling the positioning actuator component, the toothed belt is driven to run in full circulation, completing a comprehensive cleaning of all pallets and guide plates. This balances daily processing efficiency with the cleaning needs of in-depth maintenance. After the waste chips are collected, they can be discharged through scrapers, pull rods, and chip removal pipes. The cleaning operation is simple and efficient.

[0021] 3. An intelligent drilling and cutting device for automotive windshield grid processing, employing a linked design for waste chip transfer and vibration-based chip removal, eliminates the need for an additional vibration drive device: A second servo motor drives a toothed belt to transfer waste chips via a pallet, while the pallet simultaneously actuates a metal vibrating plate to generate high-frequency vibration, assisting in the sliding of waste chips on the inverted V-shaped guide plate. By achieving both "waste chip transfer" and "vibration-based anti-accumulation" functions with a single power source, the internal structure of the equipment is simplified, reducing the need for additional drive components. This lowers manufacturing costs and failure rates, reduces energy consumption, and improves structural integration and operational reliability.

[0022] 4. An intelligent drilling and cutting device for automotive windshield grid processing can clean up accumulated processing debris on the substrate surface of the positioning execution component, in the gaps of the automotive windshield grid bracket, and around the contour clamping unit without disassembling the entire positioning execution component fixture. Specifically, air is blown onto the surface of the positioning execution component using an air blowing device, directly sweeping residual debris into the debris storage grooves on both sides of the fixture. Subsequent conventional debris removal processes can then complete the transfer, guidance, and centralized discharge of the debris. This method eliminates the tedious processes of fixture disassembly, resetting, and recalibration, significantly shortening the daily table cleaning operation time and effectively improving debris cleaning efficiency. Simultaneously, it avoids positioning accuracy deviations caused by frequent fixture disassembly and assembly, ensuring long-term consistency and processing accuracy of the clamping and positioning.

[0023] 5. An intelligent drilling and cutting device based on automotive windshield grid processing, which adopts a three-axis linkage architecture of "workpiece longitudinal movement combined with processing end horizontal and vertical bidirectional movement": the carrier seat realizes long-stroke longitudinal feed through the cooperation of the first servo motor, drive gear and long rack, the horizontal linear module and the vertical linear module on the gantry realize the horizontal positioning and vertical feed of the processing end, and the linkage of the three can cover the entire processing area of ​​the workpiece without the need for multiple repositioning and clamping.

[0024] The drilling mechanism integrates a drilling spindle unit and a cutting execution unit. It can automatically switch between drilling and cutting processes by lateral translation, eliminating the need for manual tool changing and secondary clamping. This shortens the processing cycle and avoids positioning errors caused by multiple clamping, enabling integrated continuous processing of drilling and contour cutting, and significantly improving processing accuracy and production efficiency.

[0025] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention provides two technical solutions: an intelligent drilling and cutting device based on automotive windshield grille processing, specifically including the following embodiments: like Figures 1-2 The first embodiment is shown: an intelligent drilling and cutting device based on automotive windshield grid processing, including a gantry 2, and further comprising: The base 1 is located inside the gantry 2 and extends through the inside of the gantry 2 to the outside at both ends, serving as an operating platform for processing automotive windshield grilles; A horizontal linear module 3 is fixedly installed on the front of the gantry 2, and a vertical linear module 4 is also fixedly installed on the moving end of the horizontal linear module 3. A tool for drilling and cutting the front windshield grille of the car is fixedly installed on the moving end of the vertical linear module 4. The drilling mechanism 5 is controlled to perform drilling and cutting operations in the horizontal and vertical directions through the cooperation of the horizontal linear module 3 and the vertical linear module 4. The car windshield grille positioning mechanism 6 is movably mounted on the top of the base 1 for clamping the car windshield grille to be processed, so as to stabilize the position of the car windshield grille. The car windshield grille positioning mechanism 6 can simulate and conform to the irregular outer wall shape of the car windshield grille, forming a multi-point clamping effect at a single clamping part to disperse the stress at the clamping point. It can also automatically collect drilling and cutting waste after completing a single operation to avoid the impact of waste on subsequent operations. The control box 8 is fixedly installed on the side wall of the base 1 and is used to control the operation of all electrical equipment.

[0030] In this embodiment, the gantry 2 adopts a portal frame structure and is vertically fixed to the middle of the base 1. Its crossbeams are arranged horizontally along the width direction of the base 1, providing a stable rigid mounting reference for the transverse linear module 3. The transverse linear module 3 and the longitudinal linear module 4 together constitute a two-dimensional planar motion mechanism. The movement direction of the transverse linear module 3 is parallel to the width direction of the base 1, and the movement direction of the longitudinal linear module 4 is parallel to the vertical direction. The transverse linear module 3 drives the drilling mechanism 5 to complete the horizontal coordinate adjustment, and the longitudinal linear module 4 drives the drilling mechanism 5 to complete the precise control of the processing feed depth. The two work together to realize the drilling point positioning and cutting path planning under any planar coordinate.

[0031] The moving direction of the automotive windshield grille positioning mechanism 6 is consistent with the length direction of the base 1, forming a three-axis linkage machining system with the two-dimensional movement of the drilling mechanism 5, which can cover the entire machining area of ​​the automotive windshield grille. Its contour clamping function adapts to the arc, curved surface and other irregular outer walls of the grille through a multi-point contact structure, avoiding deformation and crushing of thin-walled grilles caused by stress concentration from single-point clamping; the waste chip collection function is integrated inside the positioning mechanism, and the drill chips and cutting chips generated during the machining process can fall directly into the collection channel below, eliminating the need for frequent manual cleaning of the table and ensuring the efficiency of continuous machining and the cleanliness of the machined surface.

[0032] The control box 8 has a built-in PLC control unit and motion control module, and an external operation display screen. It can preset processing programs and adjust processing parameters to realize automatic switching of drilling and cutting processes and fully automated operation of the entire process.

[0033] In this embodiment, long racks 7 are fixedly provided on both sides of the outer wall of the base 1, which are used to drive the car front windshield grille positioning mechanism 6 to move back and forth on the top of the base 1, so as to cooperate with the horizontal linear module 3 and the vertical linear module 4 to perform drilling and cutting operations on multiple positions of the car front windshield grille surface.

[0034] like Figures 3-12 The second embodiment is shown, which differs from the first embodiment in that: the car front grille positioning mechanism 6 includes a support seat 61 slidably disposed on the top of the base 1. A first servo motor 62 is fixedly disposed on the opposite positions on both sides of the bottom of the support seat 61. A drive gear 63 is fixedly disposed on the output shaft of each of the two first servo motors 62. The two drive gears 63 are respectively meshed with the long rack 7 at the corresponding positions. The interior of the support seat 61 is a cavity structure. An inverted V-shaped drilling waste guide plate 64 is fixedly disposed in the middle of the cavity structure. The top of the inverted V-shaped drilling waste guide plate 64 is high in the middle and low on both sides. Waste chip collection grooves 66 are opened on both sides of the interior of the support seat 61. The height of the two waste chip collection grooves 66 is much lower than the lowest point of the surface of the inverted V-shaped drilling waste guide plate 64.

[0035] In this embodiment, the support base 61 adopts a box-shaped structure formed by welding or casting, and is generally rectangular in shape. Its top surface is hollow, and the waste generated during processing can fall into the internal cavity through the hollow area. Two first servo motors 62 are symmetrically arranged on the left and right sides of the bottom of the support base 61, with the output shafts extending vertically downward. The drive gear 63 is fixed to the end of the output shaft by a key connection. The two first servo motors 62 drive synchronously to ensure that the force on both sides of the support base 61 is balanced, and there is no deviation or jamming during the movement process.

[0036] The inverted V-shaped drilling waste guide plate 64 has a apex angle ranging from 120° to 150°. Its surface is a smooth, wear-resistant metal plate. The top of the plate corresponds to the center of the hollowed-out area on the top surface of the support base 61. The two inclined sides extend towards the waste collection grooves 66 on both sides. After the waste falls onto the guide plate surface, it can slide down the inclined surface under its own weight and eventually flow into the waste collection grooves 66 on both sides. The waste collection grooves 66 are set along the length of the support base 61. The bottom of the groove is a flat structure used to temporarily store the sliding waste. The groove depth is not less than 50mm, providing sufficient waste storage capacity.

[0037] In this embodiment, a plurality of metal vibrating plates 65 are uniformly fixedly arranged on the top of the inverted V-shaped drilling waste guide plate 64. Vibration is generated by moving the metal vibrating plates 65 to slide the waste chips falling on the top of the inverted V-shaped drilling waste guide plate 64 into the waste chip collection grooves 66 on both sides. A scraper 67 is slidably arranged at one end of the inside of the waste chip collection groove 66. A pull rod 68 is also fixedly arranged on the side wall of the scraper 67. The pull rod 68 slides through the bearing seat 61 and is fixedly arranged with a pull ring 69. A waste chip drop opening is opened on the side of the bottom of the waste chip collection groove 66 away from the scraper 67. A chip discharge pipe 610 is fixedly arranged at the bottom of the waste chip drop opening.

[0038] The metal vibrating plate 65 is made of elastic manganese steel sheet and is installed vertically in a thin sheet shape. The bottom is fastened to the top edge of the inverted V-shaped drilling waste guide plate 64 by screws. The metal vibrating plates 65 are arranged at equal intervals along the length of the guide plate. When it is moved by an external force, the metal vibrating plate 65 generates high-frequency elastic vibration and transmits the vibration to the surface of the guide plate, causing the fine waste debris attached to the plate surface to fall off and slide, avoiding the accumulation and jamming of waste debris.

[0039] The scraper 67 is shaped to match the cross-sectional profile of the waste collection trough 66, and its bottom and side edges are tightly fitted to the trough wall. The pull rod 68 is horizontally inserted into the guide hole in the side wall of the bearing seat 61. Pulling the pull ring 69 will cause the scraper 67 to slide back and forth along the waste collection trough 66, pushing the temporarily stored waste in the trough to the waste drop outlet at the end. The waste drop outlet is a rectangular through hole. The chip discharge pipe 610 is made of rigid plastic or metal and is inserted and fixed to the bottom of the drop outlet from top to bottom. Its lower end can be connected to a waste collection box. The waste is discharged to the outside of the equipment through the chip discharge pipe 610, realizing the fixed-point collection and unified treatment of waste.

[0040] In this embodiment, a waste transfer mechanism is also provided above the cavity structure at the top of the support 61. The waste transfer mechanism includes a transmission roller 611 rotatably disposed on both sides inside the cavity structure. A toothed ring 612 is fixedly sleeved on both sides of the outer wall of the transmission roller 611. A toothed belt 613 is sleeved on both sides of the outer wall of two adjacent toothed rings 612. A plurality of pallets 614 are evenly fixedly disposed on the outer wall of two adjacent toothed belts 613. The top of the pallet 614 is recessed inward to form a waste storage groove. A second servo motor 616 is fixedly disposed on the side wall of the support 61. The output shaft of the second servo motor 616 rotates through the support 61 and is connected to one of the transmission rollers 611. The toothed belt 613 drives the plurality of pallets 614 to move synchronously, dumping the waste in the waste storage groove of the pallet 614. At the same time, the pallet 614 actuates the metal vibrating plate 65 to generate vibration.

[0041] The pallet 614 is vertically fixed to the surface of two toothed belts 613, with equal spacing between each pallet 614. The length of the pallet 614 is adapted to the width of the grid processing area. During processing, waste chips falling through the workpiece's cutouts fall directly into the waste chip storage groove of the pallet 614 and are conveyed to the end by the toothed belt 613. When the pallet 614 rotates with the belt to the turning point of the drive roller 611, the pallet 614 flips with the belt, and the waste chips in the storage groove are poured onto the inverted V-shaped drilling waste slag guide plate 64 below, completing the transfer of waste chips. At the same time, the pallet 614 will successively pass over the top of the metal vibrating plate 65 on the moving path, causing the metal vibrating plate 65 to vibrate through physical contact. Without the need for additional vibration drive components, the linkage between waste chip transfer and vibration chip removal is realized, simplifying the structure and reducing energy consumption.

[0042] The second servo motor 616 can be set to start and stop its cycle through the control box 8. After a single processing operation is completed, it will automatically run a chip removal program to achieve automatic chip removal.

[0043] In this embodiment, the top of the waste transfer mechanism is also provided with a positioning execution component 615 for contour clamping and positioning the windshield grille of a car. The positioning execution component 615 includes a base plate 6151. Multiple windshield grille brackets 6152 for lifting the windshield grille from multiple points at the bottom are uniformly fixed on the top of the base plate 6151. Multiple contour clamping units 6153 for applying clamping force to the top of the windshield grille are also provided on the top of the base plate 6151. A support plate 617 is fixedly provided on the inner wall of the bearing seat 61 and between the two transmission rollers 611 for lifting upward and contacting multiple trays 614 that are in contact with the bottom of the positioning execution component 615.

[0044] In this embodiment, the contour clamping unit 6153 includes a cylinder 61531 fixedly mounted on the top of the substrate 6151. A clamping arm 61532 is fixedly sleeved on the output of the cylinder 61531. A mounting base 61533 is also fixedly mounted on the bottom of the clamping arm 61532. A plurality of clamping posts 61534 are evenly arranged on the top of the mounting base 61533. The bottom ends of the plurality of clamping posts 61534 slide through the limiting plate 61535 and are fixedly mounted with rubber clamping heads 61536. The top end is fixedly mounted with the limiting plate 61535. A rubber clamping head 61536 is slidably sleeved on the outer wall of the clamping post 61534 and located between the rubber clamping head 61536 and the mounting base 61533. The clamping posts 61534 and the mounting base 61533 are locked in position by fastening bolts 61537.

[0045] The limiting plate 61535 is fixed to the top of the clamping column 61534 to limit the downward stroke of the clamping column and prevent the clamping column from falling out of the mounting base 61533. The fastening bolt 61537 is radially inserted through the side wall of the mounting base 61533, with its end abutting against the side wall of the clamping post 61534. For different types of grid workpieces, the fastening bolt 61537 can be released from locking the position of each clamping post 61534 first. Then, the output end of the cylinder pulls the clamping arm 61532 downward, so that the ends of multiple clamping posts 61534 contact the top of the grid and all clamping posts 61534 move upward a certain distance. Then, the fastening bolt 61537 is used to lock the position of the clamping posts 61534 to achieve simulated clamping and contouring. Then, the downward movement distance of the output shaft of the cylinder 61531 is recorded by the control box 8. For the clamping of the same batch of grids, the output shaft of the cylinder 61531 can be controlled to move downward by the same distance as the simulated contouring clamping by the control box 8, thereby completing the contouring clamping operation of the same batch of grids.

[0046] In this embodiment, the drilling mechanism 5 includes an integrated mounting base, a drilling spindle unit, and a cutting execution unit. The drilling spindle unit and the cutting execution unit are fixed side by side on the integrated mounting base, which is fixedly installed on the moving end of the longitudinal linear module 4. The drilling spindle unit is used to perform drilling operations on the windshield grille of the car, and the cutting execution unit is used to perform contour cutting operations on the windshield grille of the car.

[0047] The integrated mounting base is an L-shaped vertical mounting plate, whose back is fastened to the sliding slider of the longitudinal linear module 4 by bolts, and rises and falls synchronously with the longitudinal linear module 4. The drilling spindle unit and the cutting execution unit are fixed side by side in the transverse direction on the front of the integrated mounting base, with a fixed center distance between them. The processing position can be changed by switching the position of the transverse linear module 3, eliminating the need for manual tool changing and improving processing efficiency.

[0048] The drilling spindle unit includes a high-speed drilling spindle, drill chuck, and drilling tools. The spindle speed is adjustable from 1000 to 6000 rpm, adapting to drilling requirements for grids made of different materials such as plastic and aluminum alloy. It can complete various hole types, including round holes and countersunk holes. The cutting execution unit uses a high-speed milling spindle with a milling cutter. Through three-axis linkage, it achieves curve cutting and trimming of the outer and inner contours of the grid. Both units share the same motion control system, and the machining path can be pre-programmed. After completing the drilling process, they automatically switch positions to execute the cutting process, achieving integrated drilling and cutting machining.

[0049] In this embodiment, at least two parallel guide rails are fixedly provided on the top of the base 1 along its own length direction. A matching sliding block is fixedly provided on the bottom of the support seat 61 at the position corresponding to the guide rails. The support seat 61 realizes reciprocating movement on the top of the base 1 through the sliding cooperation between the sliding block and the guide rails. The guide rails are arranged in the inner area of ​​the two long racks 7.

[0050] The guide rail adopts a linear ball bearing guide with a precision grade of not less than IT6. It is fastened to the mounting groove on the top surface of the base 1 by bolts. The two guide rails are symmetrically distributed on the left and right sides of the base 1, located inside the long rack 7, forming a "two-sided transmission and inner-side guidance" layout, which makes the load on the bearing seat 61 more balanced and the operation more stable.

[0051] Each guide rail is equipped with at least two sliding blocks, each with an internal ball bearing circulation structure, enabling high-precision, low-friction linear motion. The top of the slider is fixedly connected to the bottom surface of the support seat 61, jointly bearing the entire weight of the support seat 61 and the workpiece. Simultaneously, it restricts the movement freedom of the support seat 61, retaining only the degree of freedom of movement along the length of the guide rail. This prevents the support seat 61 from swaying left or right or bouncing up or down during movement, ensuring the correct meshing clearance of the gears and racks, and improving machining positioning accuracy and equipment lifespan.

[0052] In this embodiment, a contoured support pad is fixedly provided on the top of each windshield grille bracket 6152. The top contour of the contoured support pad is adapted to the shape of the bottom outer wall of the corresponding support position of the windshield grille, which is used to increase the support contact area and disperse the local stress at the support point of the windshield grille.

[0053] The contoured support pad is made of wear-resistant and elastic materials such as nylon or polyurethane, and is fixed to the top support surface of the bracket by adhesive or screw fastening. Its top surface is contoured according to the bottom curved surface of the grid at the corresponding lifting position, forming a surface contact with the outer wall of the workpiece. Compared with point contact or line contact lifting methods, it can significantly increase the contact area and evenly distribute the lifting force across the entire contact surface.

[0054] Addressing the thin-walled and easily deformable characteristics of automotive windshield grilles, contoured support pads prevent workpiece dents and cracks caused by excessive localized stress. Furthermore, the flexible material avoids scratching the workpiece's surface, ensuring product surface quality. Different grille models can be fitted with contoured support pads of varying profiles, adapting to the processing needs of diverse workpieces and enhancing the equipment's versatility.

[0055] In use, the car windshield grille to be processed is first placed on the base plate 6151 of the positioning execution component 615. The workpiece is lifted from multiple points at the bottom by the contour support pads on the top of the multiple car windshield grille brackets 6152, so that the top surface of the contour support pads is completely in contact with the bottom outer wall of the workpiece at the corresponding position, thus completing the initial positioning of the workpiece. When performing contour pre-adjustment for a new type of grille workpiece, the fastening bolts 61537 are first released to lock the position of each clamping column 61534. Then, the control box 8 controls the cylinder 61531 to start, and its output end drives the clamping arm 61532 to move down, so that the multiple clamping columns 61534 on the mounting base 61533 fall synchronously until the rubber clamping head 61 at the bottom of each clamping column 61534 is engaged. 536 All abuts against the irregular surface of the top of the workpiece; the clamping arm 61532 continues to descend a preset distance, so that all clamping columns 61534 slide upward adaptively relative to the mounting base 61533 to adapt to the contour of the workpiece. The sliding limit of the clamping columns 61534 is limited by the limiting plate 61535. At this time, tighten the fastening bolt 61537 to lock the relative position of all clamping columns 61534, and complete the simulated contouring and shaping of a single clamping point; at the same time, the control box 8 records the downward stroke parameters of the output shaft of the cylinder 61531. When performing batch clamping for the same batch of grid workpieces, the control box 8 directly calls the stroke parameters and controls the output shaft of the cylinder 61531 to move down the same distance, so as to quickly complete the contouring clamping and fixing of the workpiece; Next, the control box 8 controls the equipment to enter the processing state. First, it drives the two first servo motors 62 to start synchronously, driving the drive gears 63 to mesh and transmit along the long racks 7 on both sides of the base 1, so that the bearing seat 61 moves longitudinally along the guide rail at the top of the base 1, and transports the clamped workpiece to the processing area below the gantry 2. Then, the transverse linear module 3 drives the longitudinal linear module 4 and the drilling mechanism 5 to move horizontally to position the processing coordinates. The longitudinal linear module 4 drives the drilling mechanism 5 to feed vertically. First, the drilling spindle unit of the drilling mechanism 5 completes the drilling operation of all points of the workpiece. After the drilling process is completed, the transverse linear module 3 changes position laterally to switch the processing station. Through the cutting execution unit of the drilling mechanism 5, in conjunction with the longitudinal feed of the bearing seat 61 and the transverse cutting of the transverse linear module 3, the cutting operation of the inner and outer contours of the workpiece is completed according to the preset path. Next, the drill chips and shavings generated during the processing pass through the hollow area of ​​the substrate 6151 and fall into the waste chip storage groove of the support plate 614 on the toothed belt 613 below. After a single processing cycle, routine chip removal is performed: the control box 8 controls the second servo motor 616 to start, driving the transmission roller 611 to rotate at a set angle. Under the premise that the positioning execution component 615 is kept in the installed state, the movement stroke of the support plate 614 is ensured not to exceed the coverage area of ​​the positioning execution component 615. Only the support plates 614 on both sides of the positioning execution component 615 are deflected to an inclined state with the toothed belt 613, and the waste chips in the corresponding waste chip storage groove of the support plate 614 are poured onto the inverted V-shaped drilling waste guide plate 64 below. At the same time, during the deflection movement, the support plate 614 sequentially actuates the metal vibrating plate 65 to generate high The high-frequency vibration accelerates the sliding of the waste chips on the surface of the inverted V-shaped drilling waste guide plate 64 to both sides, where they are temporarily stored in the waste chip collection grooves 66 on both sides of the bearing seat 61. When a thorough cleaning and maintenance is required, the positioning execution component 615 is first removed from the top of the bearing seat 61, and then the second servo motor 616 is started to drive the transmission roller 611 to rotate continuously. Through the meshing transmission of the toothed ring 612 and the toothed belt 613, all the pallets 614 are driven to rotate synchronously, completing the comprehensive chip removal of the entire path of the pallets and guide plate surfaces. After the waste chips are collected in the waste chip collection groove 66, the pull ring 69 is pulled to drive the scraper 67 to slide along the waste chip collection groove 66 through the pull rod 68, pushing the waste chips in the groove to the waste chip drop outlet at the end, and finally discharged to the outside of the equipment through the chip discharge pipe 610, completing the entire process of chip removal.
