Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a batch grinding device for upper and lower plates of a displacement table. Background Technology

[0002] As a core component of a precision displacement stage, the upper and lower plates of the displacement stage directly affect the positioning accuracy and operational stability of the entire stage. They are widely used in high-end fields such as precision manufacturing, semiconductor packaging, medical equipment testing, and optical instrument assembly. With the rapid development of manufacturing technology, the market has placed higher demands on the precision, efficiency, and mass production capabilities of displacement stage upper and lower plate grinding devices to meet the ever-increasing demand for high-precision components.

[0003] In existing technologies, grinding devices for upper and lower plates of a displacement table typically employ a single-part processing mode, where parts are positioned and ground one by one manually or through simple mechanical means. While this method achieves basic processing functions to some extent, it has significant shortcomings. For example, single-part processing results in longer processing times for each part, extending the overall production cycle and failing to meet the demand for rapid delivery. Furthermore, due to design limitations, mass production is difficult to achieve, requiring frequent part replacements and adjustments, leading to high labor and equipment maintenance costs. In addition, existing devices have low positioning accuracy, easily accumulating errors during multiple clamping processes, resulting in unstable precision of the machined parts, making them unsuitable for high-precision applications.

[0006] In a preferred embodiment of this utility model, the grinding machine worktable is provided with a magnetic attraction mechanism, which is used to attract and fix the end face positioning plate and the side positioning plate to the installation area.

[0007] In a preferred embodiment of this utility model, the grinding diamond wheel is mounted above the worktable of the grinding machine via a bracket and can move along the inner cavity direction to grind the upper and lower plates of the displacement table inside the inner cavity.

[0008] In a preferred embodiment of this utility model, the grinding diamond wheel is a customized structure based on the structure and material of the upper and lower plates of the displacement table, and its end shape is adapted to the grinding part of the upper and lower plates of the displacement table.

[0013] In a preferred embodiment of the present invention, the cross-section of the inner cavity is rectangular, and the length and width of the inner cavity are adapted to the length and width of the upper and lower plates of the displacement stage to be processed, respectively, for accommodating at least two parallel displacement stage upper and lower plates.

[0014] In a preferred embodiment of this invention, the size of the inner cavity is configured to accommodate several displacement stage upper and lower plates arranged in a linear array.

[0015] This utility model solves the defects existing in the background technology, and has the following beneficial effects: (1) This utility model provides a batch grinding device for upper and lower plates of a displacement table. The inner cavity is formed by the combination of the end face positioning plate, the side positioning plate and the handle, and the batch positioning mechanism is formed by the end face baffle, the side baffle and the adjusting screw.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, a batch grinding device for upper and lower plates of a displacement table includes a grinding diamond wheel 1, a grinding table 3, an end face baffle 4, a side baffle 5, an end face positioning plate 6, a side positioning plate 7, a handle 8, and adjusting screws 9. The surface of the grinding table 3 is provided with a mounting area for fixing workpieces, and this area is a flat table surface.

[0022] It should be noted that the end face positioning plate 6 and the side positioning plate 7 are fixedly connected by bolts or welding to form an inner cavity with a rectangular cross-section. The length and width of the inner cavity are adapted to the length and width of the upper and lower displacement plates 2 to be processed, respectively, and the bottom of the inner cavity is in contact with the mounting area of ​​the grinding machine worktable 3. This inner cavity can simultaneously accommodate multiple upper and lower displacement plates 2 arranged in a linear array. It is understood that the bottom of the inner cavity is completely in contact with the mounting area of ​​the grinding machine worktable 3 to ensure overall stability.

[0023] In this embodiment, the end face baffle 4 and the side face baffle 5 are respectively disposed within the inner cavity and are fitted with the inner cavity wall with a clearance, allowing them to slide along the inner cavity wall. Specifically, the end face baffle 4 abuts against the end face of the upper and lower displacement platform 2, and the side face baffle 5 abuts against the side of the upper and lower displacement platform 2. The adjusting screw 9 includes an end face adjusting screw and a side face adjusting screw. The end face adjusting screw passes through the end face positioning plate 6 horizontally and abuts against the end face baffle 4, while the side face adjusting screw passes through the side positioning plate 7 vertically and abuts against the side face baffle 5. The nut end of the adjusting screw 9 is provided with anti-slip grooves to facilitate the application of torque during manual adjustment. By rotating the adjusting screw 9, the baffle can be moved within the inner cavity, thereby pressing the arranged upper and lower displacement platform 2.

[0024] Preferably, the handle 8 is fixed to the outer wall of the side positioning plate 7 by welding, and its position facilitates the operator to move and position the entire component.

[0025] Specifically, the internal cavity structure formed by the end face positioning plate 6 and the side positioning plate 7 neatly arranges multiple displacement stage upper and lower plates 2. Then, the end face baffle 4 and the side baffle 5 are placed on the end face and side of the workpiece, respectively. By tightening the end face adjusting screw and the side adjusting screw, the baffle is pushed to move towards the workpiece until all the displacement stage upper and lower plates 2 are tightly fitted against the inner cavity wall without gaps. Finally, the grinding diamond wheel 1 is started and moved along the length of the inner cavity to perform batch processing on the part of the workpiece to be ground. Thus, by fixing multiple workpieces in one clamp, batch processing can be achieved, significantly improving production efficiency. At the same time, it avoids the accumulation of positioning errors caused by multiple clamping, thereby ensuring the consistency of processing accuracy.

[0026] In this embodiment, the grinding machine worktable 3 is equipped with a magnetic attraction mechanism. This magnetic attraction mechanism can be implemented using a permanent magnet or an electromagnet, with its magnetic pole distribution corresponding to the mounting area. Specifically, magnetically conductive material is embedded in the bottom of the end face positioning plate 6 and the side positioning plate 7. When the positioning plate assembly is placed in the mounting area, the magnetic attraction mechanism generates an attractive force to firmly fix it in place. It is understood that the strength of the magnetic attraction force should be sufficient to resist the cutting forces and vibrations generated during the grinding process. Optionally, the magnetic attraction mechanism can be equipped with an on / off control to facilitate quick installation and removal of the positioning plate assembly.

[0027] Specifically, the positioning plate assembly that forms the inner cavity is quickly fixed on the grinding machine worktable 3 by using magnetic attraction, which can replace the traditional mechanical clamping method and achieve non-contact rapid positioning. This avoids the deformation or displacement of the positioning plate caused by uneven clamping force, improves positioning accuracy and consistency of repeated positioning, and at the same time greatly shortens the tooling change time and improves equipment utilization.

[0028] In this embodiment, the grinding diamond wheel 1 is mounted above the grinding machine worktable 3 via a bracket. It should be noted that the bracket typically includes longitudinal and transverse slide rails, allowing the grinding diamond wheel 1 to move along the X, Y, and Z directions to cover the grinding surfaces of all workpieces within the cavity. The grinding diamond wheel 1 is customized based on the specific structure and material of the upper and lower plates 2 of the displacement table, and its end shape is adapted to the part to be ground (such as a plane or Goethe groove).

[0029] Furthermore, the drive motor of the grinding diamond wheel 1 can be a servo motor to achieve precise control of the feed speed and position.

[0030] Specifically, the custom-made grinding diamond wheel 1, under program control, can simultaneously grind multiple workpieces fixed in the inner cavity along a preset path. Since its shape is perfectly matched with the surface to be processed on the workpiece, it can achieve full coverage processing in one go, thereby avoiding the problem of multiple passes required by general tools. Effective grinding can be completed in a single stroke, which not only improves processing efficiency, but also reduces the problem of inconsistent surface quality caused by multiple feeds, thereby reducing tool wear and equipment energy consumption.

[0031] In this embodiment, the end face positioning plate 6, the side face positioning plate 7, the end face baffle 4, and the side face baffle 5 are all made of metal through high-precision machining and heat treatment processes. It should be noted that the optional metal materials include tool steel or mold steel. Specifically, precision machining ensures the flatness, perpendicularity, and other dimensional and positional tolerances of each plate, while subsequent heat treatment processes (such as quenching and low-temperature tempering) impart high hardness and wear resistance. Furthermore, the mating surfaces of the plates can be ground to further reduce the coefficient of friction and ensure the smooth movement of the baffles.

[0032] In this embodiment, the operator places the rectangular inner cavity assembly, formed by the fixed connection of the end face positioning plate 6 and the side positioning plate 7, into the mounting area of ​​the grinding machine worktable 3 using the handle 8. The magnetic attraction mechanism of the grinding machine worktable 3 uses magnetic attraction to firmly attach and fix the positioning assembly, ensuring that the bottom of the inner cavity is completely in contact with the mounting area without relative displacement. Then, multiple workpieces to be processed, such as the upper and lower displacement plates 2, are neatly arranged in a linear array in the inner cavity, so that the sides of the workpieces are close to the inner cavity wall. Next, the end face baffle 4 and the side baffle 5 are placed into the inner cavity, respectively, so that they correspondingly abut against the end face and side of the workpiece. Then, by rotating the end face adjusting screw and the side adjusting screw, the end face baffle 4 and the side baffle 5 are pushed to slide along the inner cavity wall, applying pressure towards the workpiece until all workpieces are tightly in contact with the inner cavity wall and the gaps are eliminated, achieving precise positioning and fixing of batch workpieces. After clamping is completed, the grinding diamond wheel 1 is started and moved to the top of the inner cavity along the XYZ direction by the bracket. According to the preset program, the end of the custom-shaped grinding diamond wheel 1 is aligned with the part of the workpiece to be ground. Then, it moves at a constant speed along the length of the inner cavity to perform one-time synchronous grinding on multiple workpieces arranged in the inner cavity until the grinding surface of all workpieces reaches the accuracy requirements.

[0033] Example 2: This example is basically the same as Example 1, except that the driving method of the grinding diamond wheel 11 and the control mechanism of the adjusting screw 9 are different.

[0034] In this embodiment, the grinding diamond wheel 11 is driven by a servo motor and uses a linear encoder to achieve closed-loop control of the feed rate, achieving a feed accuracy of 0.001 mm. The adjusting screw 9 is replaced by an electric push rod, the end of which is connected to the baffle via a ball joint. The push rod stroke is uniformly scheduled by a PLC controller, and the baffle position can be automatically adjusted by preset workpiece quantity and size parameters via a touch screen. It should be noted that the thrust of the electric push rod is set to 50~100 N to avoid excessive pressure causing damage to the workpiece surface.

[0035] Specifically, the operator inputs the model and quantity of the upper and lower plates 22 of the displacement table via a touchscreen. The system automatically calculates the required space in the inner cavity and drives the electric push rod to adjust the position of the baffle. After the workpiece is placed in the inner cavity, the electric push rod advances the baffle at a speed of 0.5 mm / s until the pressure sensor detects the preset pressure value and stops. During the grinding process, the grating ruler provides real-time feedback on the position of the diamond wheel, and the servo motor automatically compensates for the grinding allowance according to the preset program, achieving unmanned processing. This mechanism can reduce manual intervention, further shorten the processing time per batch, and avoid the loss of accuracy caused by workpiece over-positioning through pressure closed-loop control.

[0036] Based on the above description and the preferred embodiments of this utility model, it will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.

No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
