Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting aids technology, specifically a guide mechanism for a silicon carbide superhard material cutting machine. Background Technology
[0002] In the cutting process of silicon carbide superhard materials, the workpiece stage, guide rail, fixture, and tooling together constitute a key support and guiding system to ensure high precision and high efficiency in cutting. The workpiece table, as the basic platform, is mainly responsible for supporting and fixing the material to be processed, providing a stable support surface and positioning reference to ensure that the material does not shift or deform during cutting. The guide rail is installed on the workpiece table and plays a role in guiding the tool to move linearly along a predetermined path, ensuring the smoothness, straightness and accuracy of the movement, reducing deviation and improving cutting quality. In this process, it is combined with a high-precision drive device (such as a motor, lead screw or belt drive system) and an advanced CNC control system, and closed-loop adjustment is performed through real-time feedback (such as position sensors or encoders) to ensure that the movement of the fixture and workpiece conforms to the predetermined path and requirements each time. However, in order to ensure that the guide rail can be installed horizontally on the upper surface of the workpiece table, the upper surface of the workpiece table is usually designed to be horizontal, so that the guide rail can remain flat during processing or assembly, thereby ensuring the straightness of movement and the accuracy of positioning. However, if no special measures are taken to remove waste from the upper surface of the workpiece table, the chips, dust and residues generated during cutting or processing will naturally remain on the table. At this time, without special chip removal or waste removal design on the horizontal surface, it is difficult to effectively clean up the waste during processing. Utility Model Content
[0003] The purpose of this utility model is to provide a guide mechanism for a silicon carbide superhard material cutting machine. The bottom of the upper worktable is provided with a sloped surface for discharging waste material downwards, while a concave double rail seat is horizontally installed at the bottom of the upper worktable. The concave double rail seat guides the clamps on the two-column integrated table and the clamped silicon carbide workpiece to move horizontally and linearly, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a guide mechanism for a silicon carbide superhard material cutting machine, comprising a base, an upper worktable integrally formed at the top of the base, a sloped surface at the bottom of the upper worktable for downward conveying, and a concave double rail seat horizontally fixedly installed at the bottom of the upper worktable. A double-column integrated platform is slidably installed on the upper surface of the concave double rail seat, and clamps are installed at the front and rear positions of the top of the double-column integrated platform.
[0005] Preferably, the front, rear, and left sides of the upper worktable are all provided with edging.
[0006] Preferably, an opening is provided on the right outer wall of the upper worktable, and a chamfer is provided on the top edge of the upper worktable on one side of the opening.

[0009] Preferably, rectangular rubber protrusions are fixed on the left and right outer walls of the two-column integrated platform, and the gap allows the rectangular rubber protrusions to slide into.
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This silicon carbide superhard material cutting machine guide mechanism, through a structure consisting of an upper worktable, a sloped surface, a concave double-rail seat, a double-column integrated platform, and a clamp, etc., works together.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0017] Please see Figure 1-4 An embodiment of this utility model is provided: a guide mechanism for a silicon carbide superhard material cutting machine, including a base 1, an upper worktable 2 integrally formed at the top of the base 1, a sloped surface 202 at the bottom of the upper worktable 2 that is inclined downward to convey the material, and a concave double rail seat 3 horizontally fixedly installed at the bottom of the upper worktable 2. A double column integrated platform 4 is slidably installed on the upper surface of the concave double rail seat 3, and clamps 7 are installed at the front and rear positions of the top of the double column integrated platform 4.
[0018] The front, rear, and left sides of the upper worktable 2 are all provided with a surrounding edge 201. The surrounding edge 201 raises the front, rear, and left sides of the upper worktable 2 to reduce the splashing of waste materials during processing.
[0019] An opening is provided on the right outer wall of the upper workbench 2, and a chamfer is provided on the top edge of the upper workbench 2 on the side of the opening, so that the right side of the upper workbench 2 is designed as an opening, which makes it convenient for workers to use cleaning tools to discharge the residual waste in the upper workbench 2 through the slope 202 and the opening.
[0020] Two first step portions 5 are provided on one side of the top of the two-column integrated platform 4. A second step portion 6 with downward indentation is provided on the top of the two-column integrated platform 4 between the two first step portions 5. The first step portion 5 provides a retention area for the silicon carbide workpiece, so that the clamp 7 can press the silicon carbide workpiece at the first step portion 5.
[0021] Two blocks 8 are fixed on the left and right sides of the bottom of the upper worktable 2. A gap 801 is provided between the two blocks 8. Rectangular rubber protrusions 9 are fixed on the outer walls of the left and right sides of the double column integrated table 4. The gap 801 allows the rectangular rubber protrusions 9 to slide in. The gap 801 between the two blocks 8 allows the rectangular rubber protrusions 9 to pass through. When the double column integrated table 4 and the clamp 7 move to the position of the two blocks 8, the blocks 8 are used to block the rectangular rubber protrusions 9 from moving further, so as to prevent the double column integrated table 4 and the clamp 7 from disengaging from the guide stroke of the concave double rail seat 3.
[0022] In this embodiment, the two integrated column platform 4 is first slidably mounted on the top of the concave double-track seat 3. The concave double-track seat 3 guides the two integrated column platform 4 and the workpiece 7 to move linearly in the horizontal direction. The concave structure of the concave double-track seat 3 provides a precise guiding channel, ensuring that the two integrated column platform 4 and the workpiece 7 remain stable during movement and do not deviate from the trajectory. Furthermore, the rigidity and smooth guide surface of the concave double-track seat 3 reduce vibration and impact, further ensuring the smoothness of movement. The base platform 1 and the upper worktable 2 serve as the basic platform of the entire mechanism, with a robust structure and good bottom flatness, and provide a support for the concave double-track seat 3 and the two integrated column platform 7. The table 4 and the fixture 7 provide sufficient space. When the cutting machine cuts the workpiece fixed by the fixture 7, the bottom surface of the upper worktable 2 is designed as a slope 202. Gravity guides the debris, dust and other waste materials to flow along the slope 202 to the collection port on the outer wall of the upper worktable 2, effectively preventing the accumulation of waste materials inside the upper worktable 2 and ensuring the cleanliness of the working area and the smooth movement of the machine. The double-column integrated table 4, together with the concave double rail seat 3, allows the fixture 7 and the workpiece to move smoothly along the predetermined path, ensuring the accuracy and repeatability of the workpiece position during the processing. The fixture 7 is used to fix the workpiece, ensuring the stability of the workpiece during processing and movement.
[0023] It will be apparent to those skilled in the art that this invention 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 invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
