Description

Technical Field

[0002] Gantry linear guide grinding machines, as large-scale high-precision grinding equipment, are mainly used for the grinding and finishing of flat, inclined, and bottom surfaces of workpieces such as machine tool guideways, beds, templates, and plates. These machines typically employ a closed frame structure or a fixed-beam double-column structure. The worktable is driven by a double-rod hydraulic cylinder and equipped with a servo motor-driven ball screw system for both horizontal and vertical feed. Some models also integrate hydraulic-mechanical valve reversing and digital display devices. With its stable structural rigidity and precise feed control, it plays an irreplaceable role in the field of precision machining.

[0003] However, existing gantry linear guideway grinding machines still have key technological shortcomings in practical applications, making it difficult to adapt to diverse processing needs. Specifically, when grinding workpieces of different specifications, not only do the workpieces themselves have different angles, but different processing scenarios also place personalized requirements on the grinding angle. Existing equipment's angle adjustment mechanisms lack flexibility, failing to achieve precise and rapid adaptation between the grinding mechanism and the workpiece angle. This deficiency directly leads to poor adaptability of the equipment to multi-angle processing needs, limiting the processing range. This not only affects processing accuracy and workpiece pass rate but also necessitates changing tooling or adjusting the overall equipment layout to meet different angle processing requirements, significantly increasing processing costs and time consumption, and hindering the improvement of production efficiency. Therefore, this paper proposes a gantry linear guideway grinding machine that can solve the above problems. Summary of the Invention

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This invention provides a gantry linear guide grinding machine, such as... Figures 1-4 As shown, it includes: main body 11, which serves as the supporting foundation for the entire device. The system includes a gantry frame body 2, which is connected to the main body 11 via a first guide rail 3; a transport plate 4, which is mounted on the main body 11 and used to transport the processed materials, and is connected to the main body 11 via a second guide rail 5; a grinder 6, which is connected to the gantry frame body 2 via a first adjustment unit, and has a grinding head 7 at its output end, which can be replaced with different types of grinding wheels or grinding tools according to processing requirements; the first adjustment unit is used to adjust the grinding angle of the grinding head 7; and a second adjustment unit, which is mounted on the transport plate 4, is used to adjust the placement angle of the transported materials.

[0018] The first adjustment unit includes a first threaded rod 8 rotatably connected to the main body 11. A first knob 9 is fixedly connected to the end of the first threaded rod 8. A rotating block 10 is fixedly connected to the outside of the first threaded rod 8. An opening 11 is provided on the rotating block 10. The rotating block 10 is connected to the grinding machine 6 through a third adjustment unit. The first adjustment unit is the core mechanism for achieving precise adjustment of the grinding head 7 angle. It ensures the matching accuracy of the grinding angle through a two-level adjustment logic of coarse adjustment + fine adjustment.

[0019] The third adjustment unit includes a first connecting plate 12 fixedly connected to the rotating block 10. A second threaded rod 13 is threadedly connected to the first connecting plate 12. A second knob 14 is fixedly connected to the end of the first threaded rod 13. A first adjustment block 15 is fixedly connected to the upper end of the grinder 6. The side of the first adjustment block 15 is rotatably connected to the rotating block 10 via a first rotating shaft. A first inclined surface 16 is provided on the first adjustment block 15. A second adjustment block 17 is sleeved on the outer side of the second threaded rod 13. A first snap-fit ​​plate 18 is fixedly connected to the end of the second threaded rod 13. A first snap-fit ​​groove 19 is provided on the second adjustment block 17. A second inclined surface 20 is provided on the second adjustment block 17. A first snap-fit ​​protrusion 21 is provided on the first inclined surface 16. A second snap-fit ​​groove 22 that mates with the first snap-fit ​​protrusion 21 is provided on the second inclined surface 20. When it is necessary to adjust the angle of the grinding head 7, firstly by... The coarse adjustment operation adapts to the approximate angle—the operator rotates the first knob 9, causing the first threaded rod 8 to rotate, which in turn drives the rotating block 10 to rotate around the axis of the first threaded rod 8, causing the entire grinding machine 6 to rotate around the horizontal direction, thus achieving the initial coarse adjustment of the grinding head 7 angle; then, the fine adjustment operation ensures the angle is accurate—rotating the second knob 14 drives the second threaded rod 13 to move up and down along the first connecting plate 12, causing the second adjusting block 17 to rise and fall. Since the second inclined surface 20 of the second adjusting block 17 is in contact with the first inclined surface 16 of the first adjusting block 15, the rise and fall of the second adjusting block 17 will generate a lateral thrust on the first adjusting block 15, forcing the first adjusting block 15 to rotate slightly around the first rotating axis, thus achieving the fine adjustment of the grinding head 7 angle; when adjusted to the target angle, the first locking protrusion 21 and the second locking groove 22 precisely engage, using the self-locking characteristics of the thread and the limiting effect of the locking structure to ensure the stability of the grinding angle and avoid angle deviation caused by vibration during the grinding process.

[0020] The second adjustment unit includes a third threaded rod 23 threadedly connected to the transport plate 4. A third knob 24 is fixedly connected to the end of the third threaded rod 23. The transport plate 4 has a placement groove 25, and a third adjustment block 26 is disposed within the placement groove 25. The third adjustment block 26 is rotatably connected to the placement plate via a second rotating shaft 27. A fourth adjustment block 28 is sleeved on the outside of the third knob 24. A second snap-fit ​​plate 29 is fixedly connected to the end of the third threaded rod 23. A third snap-fit ​​groove 30 is provided on the third adjustment block 26. A third inclined surface 31 is provided at the lower end of the third adjustment block 26, and a fourth inclined surface 32 is provided at the upper end of the fourth adjustment block 28. The transport plate 4 has a moving groove 33. Rotating the third knob 24 drives the third threaded rod 23 to move axially along the threaded sleeve, thereby pushing the fourth adjusting block 28 to move horizontally along the moving groove 33. Since the fourth inclined surface 32 of the fourth adjusting block 28 is in close contact with the third inclined surface 31 of the third adjusting block 26, the horizontal movement of the fourth adjusting block 28 will be converted into a vertical pushing force on the third adjusting block 26, forcing the third adjusting block 26 to rotate around the second rotating shaft 27, thereby realizing the angle adjustment of the material placed on the third adjusting block 26. After the adjustment is completed, the thread self-locking characteristic of the third threaded rod 23 is used to ensure the stability of the angle of the third adjusting block 26 and avoid the angle deviation of the material during the processing.

[0021] The transport plate 4 is provided with a clamping part for clamping materials, and the clamping unit includes a power unit and a clamping unit.

[0022] The power unit includes a power motor 34, which is fixedly connected to the transport plate 4. The power motor 34 is a bidirectional motor. A reciprocating lead screw 35 is fixedly connected to the output end of the power motor 34. A reciprocating slider 44 is sleeved on the outer side of the reciprocating lead screw 35. A second connecting plate 36 is fixedly connected to the transport plate 4. The end of the reciprocating lead screw 35 is rotatably connected to the second connecting plate 36. A limit rod 37 is fixedly connected between the second connecting plate 36 and the power motor 34. The limit rod 37 passes through the reciprocating slider 44.

[0023] The clamping unit includes a third connecting plate 38 fixedly connected to the reciprocating slider 44. The third connecting plate 38 has a plurality of arrayed clamping rods 39. A guide plate 40 is fixedly connected to the end of each clamping rod 39. A fourth locking groove 41 is formed on the third connecting plate 38. A guide rod 42 is fixedly connected to the fourth locking groove 41. The guide plate 40 is connected to the fourth locking groove 41 via a spring 43 providing elasticity. When the material is adjusted to the target angle by the second adjusting unit, the clamping unit is activated. The motor 34 drives the reciprocating screw 35 to rotate forward, causing the reciprocating slider 44 to move along the reciprocating screw 35 towards the material, which in turn causes the third connecting plate 38 and the clamping rod 39 to move synchronously until the guide plate 40 is in contact with the side of the material. The reciprocating screw 35 continues to rotate, the spring 43 is compressed and generates reverse elastic pressure, so that the guide plate 40 is tightly in contact with the surface of the material, realizing flexible clamping of the material. After processing is completed, the motor 34 is started to rotate in reverse, the reciprocating slider 44 drives the clamping rod 39 to reset, and the material is released.

[0024] 1. Material preparation: The operator places the material to be processed (such as machine tool guide rail surface, bed, template, etc.) on the second adjustment unit of the transport plate 4, starts the power motor 34 of the clamping part, and initially fixes the material through the clamping unit; 2. Angle Adaptation Adjustment: According to processing requirements, the placement angle of the material is first adjusted through the second adjustment unit—rotating the third knob 24 drives the fourth adjustment block 28 to move, and the tilting surface drives the third adjustment block 26 to flip until the material reaches the target placement angle, and is fixed by thread self-locking; then the grinding angle of the grinding head 7 is adjusted through the first adjustment unit—first rotating the first knob 9 for coarse adjustment, and then rotating the second knob 14 for fine adjustment, and the grinding angle is locked by the cooperation of the first locking protrusion 21 and the second locking groove 22, thus completing the precise adaptation of "material angle - grinding angle"; 3. Processing Implementation: Start the drive mechanism of the gantry frame body 2 to move it along the first guide rail 3 to the processing area; start the drive mechanism of the transport plate 4 to move it along the second guide rail 5 to accurately transport the material to the bottom of the grinding head 7; start the grinding machine 6, and drive the grinding head 7 through the horizontal and vertical feed system to achieve precise feeding and grind the material. 4. Material unloading completed: After processing is completed, the grinding machine 6 is turned off, the clamping unit is reset, the transport plate 4 moves the processed material to the unloading area, the operator completes the unloading, and the equipment enters the next processing cycle.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
