[0027] The accompanying drawings are provided to further understand this application and form part of the specification. They are used together with the following detailed description to explain the invention, but do not constitute a limitation on the invention.

[0028] Figure 1 This is a schematic diagram of the slide clamp provided in Embodiment 1 of this application;

[0029] Figure 2 A schematic diagram of the structure of the slide clamp provided in Embodiment 1 of this application;

[0030] Figure 3 This is a cross-sectional structural diagram of the slide clamp provided in Embodiment 1 of this application. Detailed Implementation

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] Example 1

[0033] This embodiment provides a slide holder for clamping rock blocks or thin rock sheets. The slide holder is mounted on a machine tool used for cutting or milling the rock blocks or thin rock sheets. The slide holder is driven, and the cutting blade or grinding cup rotates, enabling the cutting or milling of the rock blocks or thin rock sheets.

[0034] like Figures 1 to 3 As shown, the slide clamp includes:

[0035] The fixture body 5 and the fixture base 6 can be adjusted relative to each other using shims. Besides, the fixture body 5 and the fixture base 6... Figure 1 The shape shown can also be a cylinder, i.e., a disk;

[0036] The backing is set on the fixture body and protrudes from the upper surface of the fixture body 5; the upper surface refers to the surface facing the cutting disc or grinding cup, and protruding from the upper surface of the fixture body 5 means that the upper surface of the outer edge backing is not in the same plane as the upper surface of the body.

[0037] A groove 505 is provided on the upper surface of the fixture body 5, and a through hole 506 is provided at the bottom of the groove 505, which is connected to the vacuum cavity 500 inside the fixture body 5.

[0038] The backrest can define the position of the rock block or rock sheet on the upper surface of the clamp body 5, while the groove 505 communicating with the vacuum cavity 500 can use the pressure difference to fix the rock block or rock sheet on the clamp body 5.

[0039] In this embodiment, the position of the fixture body 5 can be adjusted between the fixture body 5 and the fixture seat 6 via a shim. This allows for adjustment of the perpendicularity between the glass slide mounted on the fixture body 5 and the spindles of the slicing and grinding tools, thus improving machining accuracy. In a preferred embodiment, the shim has a hollow inner cavity and a thin wall. When adjusting the position of the fixture body 5, the shim can deform under the pressure of the fixture body, thereby adapting to a position or angle where the upper surface of the fixture body 5 is perpendicular to the spindle, further enhancing the technical effect of improving machining accuracy.

[0040] In this embodiment, the groove 505 is located within the area enclosed by the support. In this structure, the vacuum negative pressure acts on the center or near the center of the slide, which can more stably fix the slide.

[0041] In a preferred embodiment, the groove 505 is cross-shaped, and a through hole 506 is provided at the center of the bottom of the groove 505. When the glass slide is covered on the groove 505, the groove 506 is a negative pressure environment. The cross-shaped groove 505 with the through hole 506 in the center has a more uniform adsorption force on the glass slide.

[0042] In this embodiment, the vacuum chamber 500 is formed by the recessed cavity on the lower surface of the fixture body 5 and the bottom cover plate 509. The through hole 506 at the bottom of the groove 505 is connected to the vacuum chamber 500. An external vent hole 508 connected to the vacuum pump is provided on the side wall of the fixture body 5. In this embodiment, the processing of the fixture body 5 is simpler and more controllable.

[0043] The preferred embodiment provided in this example is that the support and the clamp body 5 are detachably connected. Specifically, the external support and the body are detachably connected, for example, by screws or bolts, thus facilitating adjustment of the support's position to allow the slide clamp to accommodate slides of various sizes. In this embodiment, the clamp body 5 is provided with several rectangular grooves for inserting the support. In this embodiment, the support is hexahedral, and the dimensional relationship between the support and the rectangular grooves ensures that the position of the support is fixed after insertion. In one embodiment, refer to... Figure 2 The rectangular groove includes:

[0044] Four cross-shaped central slots 501;

[0045] 4 pairs of inner layer grooves 502, each pair of inner layer grooves 502 is perpendicular to each other in length direction and forms a rectangle with two mutually perpendicular central grooves 501. A groove 505 is set in the rectangular area formed by a pair of inner layer grooves 502 and two mutually perpendicular central grooves.

[0046] Eight outer layer grooves 503 are located around the inner layer grooves 502, with two outer layer grooves 503 in each direction;

[0047] Two side slots 504 are positioned opposite each other and located around the outer slot 503.

[0048] By inserting a backing into several different rectangular grooves, the slide clamp can accommodate slides of different sizes, thus expanding the scope of application of the slide clamp provided in this embodiment.

[0049] Furthermore, multiple rock blocks or thin slices can be clamped on a single slide fixture simultaneously. After processing one rock block or thin slice, the next rock block or thin slice can be processed directly, eliminating the need to disassemble the fixture and improving processing efficiency.

[0050] In this embodiment, a replacement layer is provided on the upper surface of the fixture body 5. The replacement layer is adhesively or electrostatically attached to the upper surface of the fixture body 5. Milling processes generate many extremely fine rock powders. These powders enter the glass slide (during milling, the rock slices are adhered to the glass slide) and come into direct contact with the fixture, quickly causing wear on the upper surface of the fixture. The worn upper surface of the fixture reduces the reliability of the clamping. Therefore, providing a replacement layer allows for timely replacement of the worn replacement layer, ensuring the flatness of the upper surface of the fixture.

[0051] Example 2

[0052] This embodiment provides a cutting and grinding machine, including:

[0053] The spindle end includes a spindle and a spindle motor. One end of the spindle is connected to the spindle motor, and the other end is used to mount a grinding cup or a cutting disc. Cutting is performed by mounting the cutting disc, and milling is performed by mounting the grinding cup.

[0054] The mounting end includes the slide clamp provided in Embodiment 1 of this application, a mounting end moving unit that moves the slide clamp, and a motor mounted on the mounting end moving unit that drives the clamp body 5 to rotate. The motor is mounted on the clamp base 6.

[0055] In this embodiment, as Figure 1As shown, the clamping end moving unit (including a second-direction slider structure 701, a second-direction track device 702, a first-direction slider structure 703, and a first-direction track device 704) drives the clamp seat 6 to move in two mutually perpendicular directions in the horizontal plane. In this embodiment, the first-direction slider structure 703 and the first-direction track device 704, and the second-direction slider structure 701 and the second-direction track device 702, each include two parallel tracks and a power mechanism for linear displacement output by a lead screw nut. During the cutting or milling process, the workpiece feed speed is stable, thereby improving control accuracy.

[0056] This embodiment provides a cutting and grinding machine that can both cut rock blocks into thin rock sheets and mill the thin rock sheets to make their surface roughness meet the test requirements.
