[0002] Grinding is a key process in precision manufacturing. To meet the demands for machining accuracy, efficiency, and versatility in the manufacturing of electric spindles, the applicant has developed a grinding machine primarily for machining electric spindle parts. During the development of this grinding machine, a stone bed was used as the foundation to achieve good temperature stability and vibration reduction performance. Simultaneously, to achieve one-time machining of the inner and outer surfaces of the electric spindle parts, a layout scheme with multiple moving tables working in tandem was designed. In the development of the aforementioned grinding machine, the applicant discovered that traditional grinding equipment is typically designed for a single machining task, such as external cylindrical grinding or internal hole grinding. With increasing demands for machining efficiency, grinding equipment needs to be able to complete multiple machining tasks in a single setup. However, conventional multi-functional grinding equipment designs still suffer from the problem of a separate wheel dredging device, requiring additional movement or adjustment during the wheel dredging process, thus reducing machining efficiency. How to rationally arrange the wheel dredging device within the grinding equipment and optimize the overall layout design to improve operational convenience while maintaining equipment compactness is a pressing technical problem that needs to be solved. Summary of the Invention

A grinding wheel dressing assembly is mounted side-by-side with the workpiece mounting assembly on the first motion table in the horizontal X-axis direction. The motion stroke of the first motion table in the horizontal X-axis direction can support the workpiece mounted on the workpiece mounting assembly to be processed by the outer grinding wheel mounted on the outer grinding wheel mounting assembly and the inner grinding wheel mounted on the inner grinding wheel mounting assembly, respectively. It can also support the grinding wheel dressing assembly to grind the outer grinding wheel mounted on the outer grinding wheel mounting assembly and the inner grinding wheel mounted on the inner grinding wheel mounting assembly, respectively.

[0005] As an optimization and / or instantiation of the above-mentioned multifunctional composite grinding equipment, further: the grinding wheel mounting assembly for inner machining simultaneously has an inner roughing grinding wheel mounting joint and an inner finishing grinding wheel mounting joint; the inner roughing grinding wheel mounting joint and the inner finishing grinding wheel mounting joint are arranged side by side along the horizontal X-axis; the movement stroke of the first motion table in the horizontal X-axis direction can also support the grinding wheel draughter mounted on the grinding wheel draughter mounting assembly to draught the inner roughing grinding wheel mounted on the inner roughing grinding wheel mounting joint and the inner finishing grinding wheel mounted on the inner finishing grinding wheel mounting joint, respectively.

[0006] As an optimization and / or instantiation of the aforementioned multi-functional composite grinding equipment, further: the travel of the first, second, and third motion tables is all within the range defined by the edge of the bed; the bed is designed with a corner, and the inside corner formed by this corner is set as the worker's operating area. When viewed from the worker's operating area along the horizontal X-axis towards the multi-functional composite grinding equipment, the first motion table is located to the left or right of the worker's operating area, and the second and third motion tables are located in front of the worker's operating area.

[0010] As an optimization and / or instantiation of the above-mentioned multifunctional composite grinding equipment, further: the sidewall of the outer housing is arranged around the outer edge of the bed to form a corner sidewall.

[0011] As an optimization and / or instantiation of the above-mentioned multifunctional composite grinding equipment, further: the inner corner portion of the corner-shaped sidewall is provided with an arc-shaped sliding door that is recessed into the multifunctional composite grinding equipment.

Detailed Implementation

[0020] The present invention will now be clearly and completely described in conjunction with the accompanying drawings.

Before describing the present invention in conjunction with the accompanying drawings, it should be particularly noted that:

[0021] The technical solutions and features provided in the various sections, including the following description, can be combined with each other without conflict. Furthermore, where possible, these technical solutions, features, and related combinations can be given specific technical subject matter and protected by relevant patents.

[0022] The embodiments of the present invention described below are generally only some embodiments and not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of patent protection.

[0023] The terms "comprising," "including," "having," and any variations thereof in this specification, the corresponding claims, and related sections are intended to cover non-exclusive inclusion. Other related terms and units can be reasonably interpreted based on the relevant content provided in this specification.

[0024] This invention provides a multifunctional composite grinding device, mainly used for precision grinding of electric spindle parts. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a three-dimensional view of the grinding equipment (with the top transparent) according to an embodiment of the present invention. Figure 2 for Figure 1 The view of the grinding equipment shown after removing the outer casing. Figure 3 for Figure 1 A top view of the grinding equipment shown. Figures 1-3 As shown, the grinding equipment is a multi-functional composite grinding equipment, mainly used for precision grinding of electric spindle parts.

[0026] The grinding equipment includes: a bed 1; a motion table 2 mounted on the bed 1, the motion table 2 being mounted on the bed 1 via a guide and drive mechanism with linear guides and ball screw pairs; and functional components 3 mounted on the motion table 2 (including the following workpiece mounting assembly 31, outer side grinding wheel mounting assembly 33, inner side grinding wheel mounting assembly 34, and grinding wheel dressing assembly 32).

[0027] In addition, the grinding equipment is equipped with an external lubrication station 5, which can supply lubricating oil to the guide and drive mechanisms of each moving table 2. Waste lubricating oil is collected through the lubricating oil return pipeline in the bed 1 and returned to the lubrication station 5 for filtration and reuse.

[0028] The machine bed 1 is equipped with three sets of motion tables 2, namely a first motion table 21, a second motion table 22, and a third motion table 23. The first motion table 21 is configured to move along the horizontal X-axis and is equipped with a workpiece mounting assembly 31 and a grinding wheel dressing assembly 32 parallel to the workpiece mounting assembly 31 in the horizontal X-axis direction. The second motion table 22 is configured to move along the horizontal Y-axis and is equipped with an outer grinding wheel mounting assembly 33. The third motion table 23 is arranged parallel to the second motion table 22 in the horizontal X-axis direction, and is also configured to move along the horizontal Y-axis and is equipped with an inner grinding wheel mounting assembly 34.

[0029] By employing a coordinated layout of three sets of motion tables (first motion table 21, second motion table 22, and third motion table 23) on the bed 1, this multi-functional composite grinding equipment achieves the technical goal of completing multiple grinding processes in a single setup. The design of setting the first motion table 21 to move along the horizontal X-axis, while setting the second and third motion tables 22 and 23 to move along the horizontal Y-axis, allows the grinding equipment to simultaneously support precise positioning in two directions, significantly improving processing flexibility. In particular, the structure of mounting the workpiece assembly 31 and the grinding wheel dressing assembly 32 side-by-side on the first motion table 21 fully utilizes the movement trajectory of a single motion table, improving space utilization efficiency and simplifying the equipment structure.

[0030] The first motion table 21's travel in the horizontal X-axis direction can support the workpiece mounted on the workpiece mounting assembly 31 to be processed by the outer grinding wheel mounted on the outer grinding wheel mounting assembly 33 and the inner grinding wheel mounted on the inner grinding wheel mounting assembly 34, respectively. It can also support the grinding wheel drier mounted on the grinding wheel drier mounting assembly 32 to dredge the outer grinding wheel mounted on the outer grinding wheel mounting assembly 33 and the inner grinding wheel mounted on the inner grinding wheel mounting assembly 34, respectively.

[0031] The design of the first motion table 21 in the horizontal X-axis direction cleverly solves the problem that traditional grinding equipment requires different devices or switching processes for workpiece processing and grinding wheel dredging. Through the reciprocating motion of a single motion table, the workpiece can be sent to different grinding wheels for processing, and the grinding wheel dredging device can be sent to each grinding wheel for dredging, significantly improving processing continuity and efficiency.

[0032] The inner grinding wheel mounting assembly 34 includes both an inner roughing grinding wheel mounting joint 341 and an inner finishing grinding wheel mounting joint 342. The inner roughing grinding wheel mounting joint 341 and the inner finishing grinding wheel mounting joint 342 are arranged side by side along the horizontal X-axis. The movement stroke of the first motion table 21 in the horizontal X-axis direction can also support the grinding wheel draughter mounted on the grinding wheel draughter mounting assembly 32 to draught the inner roughing grinding wheel mounted on the inner roughing grinding wheel mounting joint 341 and the inner finishing grinding wheel mounted on the inner finishing grinding wheel mounting joint 342, respectively.

[0033] This internal grinding wheel mounting assembly 34, which integrates both an internal roughing grinding wheel mounting joint 341 and an internal finishing grinding wheel mounting joint 342, further enhances the equipment's process integration. By integrating internal roughing and finishing functions into a single assembly, the number of steps involved in replacing, clamping, and adjusting the internal roughing and finishing grinding wheels during machining is reduced, thus lowering cumulative errors and improving machining accuracy. Simultaneously, the grinding wheel drinder mounting assembly 32's function of dredging both internal roughing and finishing grinding wheels ensures the machining performance and geometric accuracy of each wheel, extends wheel life, and guarantees consistent machining quality. This highly integrated functional layout significantly improves the equipment's machining capacity and efficiency.

[0034] The travel of the first motion table 21, the second motion table 22, and the third motion table 23 is all within the range defined by the edge of the bed 1. The bed is designed with a corner, and the inside corner formed by the corner is set as the worker's operating area W. When viewed from the worker's operating area W along the horizontal X-axis towards the multi-functional composite grinding equipment, the first motion table 21 is located on the left or right side of the worker's operating area W, and the second motion table 22 and the third motion table 23 are located on the front side of the worker's operating area W.

[0035] This structure, combining the corner design of the bed 1 with the layout of the motion tables, fully considers ergonomic principles and provides a more rational operating space. By designating the inner corner as the worker's operating area W and rationally arranging the motion tables around it, operators can complete the operation and monitoring of each functional unit 3 within the shortest possible travel distance. In particular, placing the first motion table 21 (responsible for workpiece clamping and grinding wheel dressing) on ​​the left or right side of the worker's operating area W, while placing the second motion table 22 and the third motion table 23, which perform grinding operations, on the front side of the worker's operating area W, ensures both operator convenience and safety during the machining process. Simultaneously, the design that the travel stroke of each motion table is within the edge range of the bed 1 ensures the compactness of the equipment and efficient space utilization.

[0036] The workpiece mounting assembly 31 is closer to the worker's operating area W than the grinding wheel dressing assembly 32. Furthermore, the inner grinding wheel mounting assembly 34 is closer to the worker's operating area W than the outer grinding wheel mounting assembly 33.

[0037] The layout design of this functional component 3 further optimizes operational convenience and processing efficiency. The workpiece mounting assembly 31 is positioned closer to the operator's work area W, facilitating workpiece loading, unloading, and inspection by the operator, reducing operator movement distance and work time, and improving work efficiency. Simultaneously, the grinding wheel mounting assembly 34 for internal machining is positioned closer to the operator's work area W than the grinding wheel mounting assembly 33 for external machining. Considering that internal machining typically requires more precise adjustments and more frequent observation, this layout allows the operator to more easily monitor the internal machining process and promptly detect and handle any machining abnormalities.

[0038] In addition, the aforementioned grinding equipment also includes an outer housing 4, which is mounted above the bed 1. The side walls of the outer housing 4 are arranged around the outer edge of the bed 1 to form corner-shaped side walls. The inner corner of the corner-shaped side wall is provided with an arc-shaped sliding door 41 that is recessed into the multi-functional composite grinding equipment. The arc-shaped sliding door 41 corresponds to the position of the worker's operating area W.

[0039] The design of this outer casing 4 balances ease of operation with safety protection. Installed above the machine bed 1, the outer casing 4 effectively prevents the splashing of cutting fluid and debris during machining, maintaining a clean working environment. The corner-shaped sidewalls match the corner shape of the machine bed 1, resulting in a harmonious and aesthetically pleasing overall design. In particular, the recessed, curved sliding door 41 at the inner corner corresponding to the worker's operating area W saves operating space while providing excellent visibility and access. The curved sliding door 41's opening and closing does not occupy space in the worker's operating area W, avoiding the spatial interference problems that may arise from traditional sliding or hinged doors. Simultaneously, the curved trajectory provides a larger opening range, increasing the usable area of ​​the worker's operating area W.

[0040] The bed frame 1 is made of stone, and the outer edge of the stone bed frame has spaced-apart mounting holes for the outer casing 4, which is bolted onto these mounting holes. The stone bed frame is made of marble, granite, or mineral castings. In this embodiment, the stone bed frame is made of marble.

[0041] The design of the stone bed 1 significantly improves the stability and precision of the equipment. The marble bed possesses excellent vibration absorption, thermal stability, and high rigidity, effectively suppressing vibrations generated during processing, reducing thermal deformation, and ensuring machining accuracy. The spaced mounting holes for the outer housing 4 on the outer edge of the stone bed 1 provide a reliable mounting method, and bolt connections ensure a secure connection between the outer housing 4 and the bed 1. Compared to traditional cast iron or steel bed structures, the marble bed offers better vibration damping and thermal stability, making it particularly suitable for the requirements of high-precision grinding. Furthermore, the marble material's corrosion resistance ensures long-term stable operation and precision maintenance of the equipment.

[0042] The foregoing has described the relevant content of this utility model. Those skilled in the art will be able to implement this utility model based on these descriptions. All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of this utility model.
