Description

Technical Field

[0001] This invention relates to the technical field of grinding and cutting gantry machining centers, specifically to a multi-angle grinding precision gantry guideway grinding machine. Background Technology

[0002] In the field of modern mechanical manufacturing, precision machining of metal workpieces has become a core process. High-end manufacturing industries, such as aerospace, automobile manufacturing, and mold processing, place stringent demands on the surface accuracy and machining of complex angles. Traditional single-function grinding and cutting equipment suffers from low processing efficiency and large footprint due to its independent functions and dispersed equipment. For example, the cylinder head plane and side chamfer of an automobile engine block need to be machined on flat grinding equipment and oblique grinding equipment respectively. This not only requires frequent equipment changes but also introduces positioning errors due to multiple clamping operations, affecting the accuracy of the workpiece.

[0003] While early gantry machining centers possessed multi-axis linkage capabilities, most could only perform single functions such as flat grinding or slant grinding. This was insufficient for slant surface machining requirements, necessitating the use of specialized slant grinding equipment and increasing production line investment costs. Furthermore, traditional slant grinding structures often employed fixed-angle grinding wheel sets, with adjustments for the wheel tilt angle via mechanical forks offering low precision, making it difficult to meet the high-precision slant surface machining requirements. Moreover, grinding depth adjustment relied on manual hand-cranked screws, which was unsuitable for the depth control demands of precision mold machining.

[0004] Furthermore, it is not convenient to maintain. The drive structure is integrated with the main frame design. For example, the spindle drive group is fixed on the gantry frame. During maintenance, the entire frame structure needs to be disassembled, which takes a long time for each maintenance and seriously affects production efficiency. Summary of the Invention

[0005] To achieve flexible and high-precision grinding and easy maintenance, this application provides a multi-angle grinding precision gantry guideway grinding machine.

[0006] This invention is implemented as follows:

[0007] A multi-angle precision gantry grinding machine includes a machine tool and a gantry. The gantry is vertically mounted above the machine tool. A moving beam is slidably mounted on the gantry, and two sets of servo motors are fixedly mounted on both sides of the upper end face of the gantry. The output ends of the servo motors are connected to worm gears that drive the moving beam to rise and fall. A first movable seat and a second movable seat are slidably mounted on both sides of the front end face of the moving beam. A first driving component that drives the first movable seat to rise and fall and a second driving component that drives the second movable seat to rise and fall are vertically mounted on the upper end of the moving beam. A set of flat grinding wheels is fixedly mounted on the front end face of the first movable seat, and a flat grinding spindle motor that drives the set of flat grinding wheels to rotate is also fixedly mounted on the first movable seat. A set of slant grinding wheels is fixedly mounted on the front end face of the second movable seat.

[0008] By adopting the above technical solution, and by setting up a moving beam, a servo motor, a first movable seat, a second movable seat, a flat grinding wheel set, and an oblique grinding wheel set, the lifting and lowering of the moving beam, as well as the integration of flat grinding and oblique grinding functions, are achieved. The servo motor drives the moving beam to lift and lower via a worm gear, enabling precise control of the beam's height to adapt to the processing requirements of workpieces of different heights. The first and second movable seats can be raised and lowered independently on the moving beam, allowing the flat grinding wheel set and the oblique grinding wheel set to flexibly adjust their heights for flat grinding and oblique grinding operations, respectively, greatly improving processing flexibility and efficiency. The flat grinding spindle motor drives the flat grinding wheel set to rotate, providing power for the flat grinding process and ensuring the accuracy and quality of the flat grinding.

[0009] Furthermore, the machine tool includes a bed and foot supports. The foot supports are evenly installed on both sides of the lower end face of the bed and are fixedly connected to the bed. A worktable is installed above the bed, and a hydrostatic guide rail for sliding installation of the worktable is also provided on the upper end face of the bed.

[0010] By adopting the above technical solution, the machine tool employs a bed and foot support structure. The foot supports are evenly installed on both sides of the lower end face of the bed and fixedly connected, which effectively distributes the weight of the machine tool, improves its stability, and reduces vibration during operation. A worktable is mounted above the bed, and a hydrostatic guide rail is provided on the upper end face of the bed. The hydrostatic guide rail features high precision, high rigidity, and low friction, ensuring the stability and accuracy of the worktable during sliding, thereby improving the precision of workpiece machining.

[0011] Furthermore, the gantry frame includes gantry uprights and crossbeams. The gantry uprights are in two sets, and the two sets of gantry uprights are vertically fixed on both sides of the bed. The crossbeams are fixedly installed between the two sets of gantry uprights.

[0012] By adopting the above technical solution, the gantry frame consists of gantry uprights and crossbeams. Two sets of gantry uprights are vertically fixed on both sides of the machine bed, and the crossbeams are fixedly installed between the two sets of gantry uprights, forming a stable frame structure. This structural design can provide stable support for the moving beam, ensuring the smoothness and accuracy of the moving beam during lifting, while also enhancing the structural strength and stability of the entire gantry machining center.

[0013] Furthermore, the slanted grinding wheel assembly includes a rotatable seat assembly, an integrated housing, a grinding component, and a spindle drive assembly for driving the grinding component to rotate. The rotatable seat assembly is fixedly installed on the front end face of the second movable seat. The integrated housing is rotatably installed on the rotatable seat assembly, and a first drive component for driving the rotatable seat assembly to rotate is provided in the integrated housing. The grinding component is slidably installed at the lower end of the integrated housing, and a second drive component for driving the grinding component to extend and retract within the integrated housing is provided in the integrated housing. The spindle drive assembly is fixedly installed on the integrated housing, and the output end of the spindle drive assembly is slidably connected to the grinding component.

[0014] By adopting the above technical solution, the combined design of the rotatable seat assembly, integrated housing, grinding component, and spindle drive assembly of the slant grinding wheel set achieves adjustable slant grinding angle and telescopic function of the grinding component. The rotatable seat assembly is fixed to the front end face of the second movable seat, and the integrated housing is rotatably mounted on the rotatable seat assembly. Driven by drive component one, the integrated housing can be rotated, enabling precise adjustment of the slant grinding angle to meet the slant grinding requirements of different workpieces. The grinding component is slidably mounted on the lower end of the integrated housing. Drive component two can drive the grinding component to telescopically extend and retract within the integrated housing, facilitating adjustment of the grinding depth and improving the flexibility and precision of slant grinding. The spindle drive assembly provides rotational power to the grinding component, ensuring the efficiency and quality of slant grinding. By integrating rotation, telescopic, and various drive structures into the slant grinding wheel set, installation and maintenance are more convenient. In case of problems, the entire slant grinding wheel set can be easily disassembled for repair, making operation much more convenient compared to traditional structures integrated into gantry machining centers.

[0015] Furthermore, the rotatable seat assembly includes a connecting plate seat and a connecting shaft. The connecting shaft is fixedly installed at the center of the connecting plate seat and rotatably installed on the integrated housing. The connecting plate seat is evenly provided with a plurality of stepped holes connected to the second movable seat along the circumferential direction. The first drive assembly includes a first motor, a drive worm, and a drive worm wheel that cooperates with the drive worm. The first motor is fixedly installed on the inner side of the integrated housing. One end of the drive worm is connected to the output end of the first motor. The drive worm wheel is sleeved and fixed on the connecting shaft.

[0016] By adopting the above technical solution, the structural design of the connecting disc and connecting shaft of the rotatable seat assembly allows the integrated shell to rotate around the connecting shaft. The stepped hole on the connecting disc facilitates connection with the second movable seat, ensuring the stability of the connection. The drive assembly adopts a transmission method of motor, drive worm gear, and drive worm wheel, which features high transmission efficiency, high transmission accuracy, and good self-locking properties. It can precisely control the rotation angle of the integrated shell and achieve precise adjustment of the skew grinding angle.

[0017] Furthermore, the integrated shell includes a main frame shell and an outer cover for installing the second drive component. The inner side of the main frame shell is provided with a guide groove for sliding installation of the grinding component. The outer cover includes a cover plate and a right-angle frame. The right-angle frame is evenly installed on the four corners of the inner side of the cover plate and is fixedly connected to the cover plate. A guide rail is also fixedly installed on the inner side of the cover plate.

[0018] By adopting the above technical solution, the integrated design of the main frame and outer cover provides installation space and protection for the grinding assembly and drive assembly II within the main frame. The guide groove on the inner side of the main frame guides the sliding of the grinding assembly, ensuring its smoothness and precision. The combination of the cover plate and right-angle frame of the outer cover enhances its strength and stability. The guide rail on the inner side of the cover plate provides sliding guidance for the moving seat plate of drive assembly II, ensuring its operational accuracy.

[0019] Furthermore, a stabilizing bearing is slidably mounted on the lower end of the main frame shell. The stabilizing bearing includes a bushing and side wing plates. The side wing plates are symmetrically mounted on both sides of the bushing and are integrally formed with the bushing. Two sets of concave clamps for sliding mounting of the side wing plates are symmetrically mounted on the inner side of the main frame shell. The concave clamps are fixedly connected to the main frame shell.

[0020] By adopting the above technical solution, the concave clamp on the inner side of the main frame provides a sliding track for the side wing plate, allowing the stabilizing bearing to slide smoothly within the main frame. The stabilizing bearing supports and stabilizes the grinding rod, reducing vibration and shaking during grinding, improving grinding accuracy and quality. Furthermore, the stabilizing bearing extends and retracts synchronously during the extension and retraction of the grinding assembly, ensuring stable grinding regardless of its length.

[0021] Furthermore, the grinding assembly includes a rotating roller, a limiting block, a grinding rod, and a grinding disc. The limiting block is installed on both sides of the rotating roller and is rotatably connected to the rotating roller. The head of the grinding rod is fixedly installed at the center of the lower end face of the rotating roller and is rotatably installed in the bushing. The grinding disc is fixedly installed at the outer end of the grinding rod.

[0022] By adopting the above technical solution, the structural design of the grinding assembly's rotating roller, limiting block, grinding rod, and grinding disc effectively integrates the grinding function. The limiting block is rotatably connected to the rotating roller, ensuring its flexible rotation. The grinding rod head is fixed at the center of the lower end face of the rotating roller and rotatably mounted in a bushing, allowing the grinding rod to rotate stably. The grinding disc is fixedly mounted on the outer end of the grinding rod, enabling effective grinding of the workpiece.

[0023] Furthermore, the second drive assembly includes a second motor, a drive screw, a movable seat plate, and a limiting clamping plate for clamping the rotating roller. The drive screw is rotatably mounted on the inner side of the cover plate, the second motor is fixedly mounted on the inner side of the cover plate, and the second motor is used to drive the drive screw to rotate. The movable seat plate is slidably mounted on the guide rail, and the side of the movable seat plate is provided with a threaded sleeve that cooperates with the drive screw. The limiting clamping plate is fixedly mounted on both ends of the movable seat plate.

[0024] By adopting the above technical solution, the structural design of the second motor, drive screw, moving base plate, and limiting clamping plate in drive component two enables the grinding component to extend and retract within the integrated housing. The second motor drives the drive screw to rotate, and the drive screw engages with the threaded sleeve on the side of the moving base plate, converting the rotational motion into linear motion, allowing the moving base plate to slide on the guide rail. The limiting clamping plate is fixedly installed at both ends of the moving base plate, clamping the rotating roller, thereby driving the grinding component to extend and retract, precisely controlling the grinding depth, and improving processing accuracy and efficiency.

[0025] Furthermore, the spindle drive assembly includes an angle grinder spindle motor, a transmission rod, and a connector plate. The angle grinder spindle motor is fixedly installed on the upper end face of the main frame. One end of the transmission rod is connected to the output end of the angle grinder spindle motor, and the connector plate is fixedly installed on the other end of the transmission rod. A limiting groove is provided at the upper center of the roller section for the transmission rod and the connector plate to be inserted and installed.

[0026] By adopting the above technical solution, the structural design of the angle grinder spindle motor, transmission rod, and connector plate in the spindle drive assembly provides rotational power for the grinding components. The angle grinder spindle motor transmits power to the rotating roller section through the transmission rod and connector plate, which in turn engage with the limiting groove of the rotating roller section, driving the grinding components to rotate. This connection method ensures the stability and reliability of power transmission, while also facilitating installation and disassembly, and simplifying equipment maintenance and repair.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) By setting up a flat grinding wheel set and an oblique grinding wheel set, the present invention can simultaneously realize flat grinding and oblique grinding operations, integrating the functions of flat grinding and oblique grinding into one, and can perform efficient and precise grinding and cutting processing on workpieces of different shapes and angles, meeting diverse processing needs, reducing the number of processing equipment and the floor space occupied, and reducing production costs. The moving beam can be raised and lowered on the gantry, and the first movable seat and the second movable seat can be raised and lowered independently on the moving beam, so that the grinding and cutting tools can be flexibly adjusted to adapt to workpieces of different sizes and shapes.

[0029] (2) This invention designs the slant grinding wheel assembly into a structure that combines a rotatable base assembly, an integrated shell, a grinding component, and a spindle drive assembly, thereby achieving adjustable slant grinding angles and telescopic functionality of the grinding component. It adds a telescopic structure to the traditional grinding angle adjustment, further improving the flexibility of grinding. The integrated shell is designed as a structure that combines a main frame shell and an outer cover, and the openable outer cover facilitates better maintenance later. During maintenance, the slant grinding wheel assembly can be disassembled as a whole, eliminating the need to operate on a large machining center, effectively reducing maintenance difficulty. Furthermore, the various components are reasonably distributed on the main frame shell and the outer cover, ensuring that there is no mutual interference between the components during use, and also making it easy to perform maintenance operations separately.

A limiting groove 811 is provided at the center of the upper end of the roller section 81 for the transmission rod 92 and the connector plate 93 to be inserted and installed. The structural design of the angle grinder spindle motor 91, transmission rod 92, and connector plate 93 in the spindle drive assembly 9 provides rotational power for the grinding assembly 8. The angle grinder spindle motor 91 transmits power to the roller section 81 through the insertion and cooperation of the transmission rod 92 and the connector plate 93 with the limiting groove 811 of the roller section 81, driving the grinding assembly 8 to rotate. This connection method can ensure the stability and reliability of power transmission, and also facilitates installation and disassembly, making it convenient for equipment maintenance and repair.

[0052] Working principle: The multi-angle grinding gantry machining center includes the following steps in actual use.

[0053] Overall Structure and Basic Motion: The gantry 2 consists of two sets of gantry uprights 21 and crossbeams 22 forming a stable frame, vertically mounted above the machine tool 1, providing solid support for the moving beam 3. The machine tool 1 adopts a structure with a bed 11 and foot supports 12. The foot supports 12 are evenly distributed on both sides of the lower end face of the bed 11, distributing the weight of the machine tool 1 and enhancing stability. The hydrostatic guide rails 111 on the bed 11 support the sliding of the worktable 13, ensuring the smooth operation of the worktable 13 with high precision and low friction characteristics, laying a foundation for the accuracy of workpiece processing. The moving beam 3 is raised and lowered by two sets of servo motors 20 driven by worm gears, which can accurately position the height to meet the processing requirements of different workpieces. At the same time, the first movable seat 31 and the second movable seat 32 are raised and lowered independently on both sides of the front end face of the moving beam 3, respectively driving the flat grinding wheel set 4 and the slant grinding wheel set 5 to flexibly adjust their height, realizing the integration of flat grinding and slant grinding functions, improving processing flexibility and efficiency.

[0054] During the surface grinding process, the surface grinding wheel assembly 4 is fixed to the front end face of the first movable seat 31 and is driven to rotate by the surface grinding spindle motor 30 to provide power for the surface grinding process and ensure the accuracy and quality of the surface grinding process.

[0055] During slant grinding, the rotatable seat assembly 6 of the slant grinding wheel assembly 5 is fixed to the front end of the second movable seat 32. The integrated shell 7 is rotatably mounted on the connecting plate seat 61 of the rotatable seat assembly 6 via the connecting shaft 62. The motor 601 in the first drive assembly 60 drives the drive worm gear 602 to rotate. The drive worm wheel 603 cooperates with the drive worm gear 602, driving the integrated shell 7 to rotate around the connecting shaft 62, thereby achieving precise adjustment of the slant grinding angle. The grinding assembly 8 is slidably mounted on the lower end of the integrated shell 7. The motor 801 in the second drive assembly 80 drives the drive screw 802 to rotate. Through cooperation with the threaded sleeve 805 of the movable seat plate 803, the rotational motion is converted into linear motion, causing the movable seat plate 803 to slide along the guide rail 723, which drives the grinding assembly 8 held by the limit clamping plate 804 to extend and retract, thereby adjusting the grinding depth. The angle grinding spindle motor 91 of the spindle drive assembly 9 is connected to the limiting slide groove 811 of the roller section 81 via the transmission rod 92 and the plug plate 93, transmitting power to the grinding assembly 8 to drive the grinding disc 84 to rotate and complete the oblique grinding process. In addition, the stabilizing bearing 73 slides at the lower end of the main frame shell 71, and its side wing plate 732 cooperates with the concave clamp 712 to support the grinding rod 83 during the grinding process, reduce vibration, ensure grinding accuracy and stability, and can extend and retract synchronously with the grinding assembly 8 to adapt to different grinding depth requirements.
