[0030] 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.

[0031] Example 1

[0032] Reference Figures 1 to 4 The dual-purpose machine tool for cutting and grinding thin rock sections provided in this embodiment includes:

[0033] The spindle end 100 includes a spindle 101 and a spindle motor. One end of the spindle 101 is connected to the spindle motor via six axial spindle fixing bolts 3. The other end of the spindle 101 is connected to a cutting disc clamping flange or a grinding cup clamping flange. The ends of the cutting disc clamping flange and the grinding cup clamping flange connected to the spindle are the same. The clamping end of the cutting disc clamping flange is used to connect the cutting disc, and the clamping section of the grinding cup clamping flange is used to connect and clamp the grinding cup.

[0034] The tool clamping end includes a clamp 5 for clamping the workpiece, a clamping seat 6 connecting the clamp 5, a 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) that drives the clamping seat 6 to move, and a clamping motor 601 mounted on the clamping end moving unit that drives the clamp 5 to rotate.

[0035] The clamp 5 is provided with multiple first grooves with rectangular cross sections, and the first grooves include:

[0036] The four center slots 501 are arranged in a cross shape at the center of the working surface of the fixture 5.

[0037] The inner layer groove 502 consists of four pairs of inner layer grooves 502. The length directions of the two grooves in each pair of inner layer grooves 502 are perpendicular to each other and form a rectangle with two mutually perpendicular central grooves 501. A groove 505 is provided in the rectangular area formed by a pair of inner layer grooves 502 and two mutually perpendicular central grooves 501. The bottom of the groove is connected to a vacuum source.

[0038] Before processing, adjust the six spindle fixing bolts 3 between the spindle 101 and the spindle motor. At the same time, continuously measure the parallelism between the plane A where the spindle end face is located and the plane B where the working surface of the fixture 5 is located, so that the spindle 101 is parallel to the surface of the rock sample to be cut or polished, thereby improving the processing accuracy.

[0039] Furthermore, in this embodiment, multiple rock blocks or rock slices can be clamped on a single glass slide fixture simultaneously. By clamping multiple rock blocks or rock slices at the same time, the processing of the next rock block or rock slice can be carried out directly after processing one rock block or rock slice, eliminating the need to disassemble the fixture and improving processing efficiency.

[0040] To reduce the cost of the cutting and grinding machine tool, the first groove on the fixture 5 provided in this embodiment further includes:

[0041] Eight outer grooves 503 are located around the inner grooves 502, so a support can be inserted in the outer grooves 503 and not inserted in the inner grooves 502, thus accommodating rock slices of other sizes. In the preferred technical solution, two outer grooves 503 are provided in each direction, which can more stably fix larger rock slices.

[0042] Furthermore, the first groove also includes:

[0043] Two side grooves 504 are set opposite each other and located on the periphery of the outer groove 503, increasing the applicability of the fixture 5.

[0044] In addition to fixing the rock sheet by leaning against the mountain, this embodiment also uses negative pressure to fix it in order to increase the reliability of the clamping. Therefore, in the preferred embodiment, the groove 505 is cross-shaped and a first vent 506 is provided at the center of the bottom of the groove 505.

[0045] In the above embodiment, the first groove is used to insert the backing, and the backing is inserted into the first groove and protrudes from the upper surface of the clamp 5 to achieve positioning of the rock sheet.

[0046] In the preferred embodiment provided in this example, the backing is a regular hexahedron, and the backing and the first groove are in a transition fit, so the position is fixed after the backing is inserted into the first groove.

[0047] In this embodiment, a hollow shim with an inner cavity is provided between the clamp 5 and the clamp seat 6. The position of the clamp 5 can be adjusted by placing the shim between the clamp 5 and the clamp seat 6, thus adjusting the perpendicularity between the rock slice loaded on the clamp 5 and the spindle of the slicing and grinding tools, further improving processing accuracy. In a preferred embodiment, the shim has a hollow inner cavity and a thin wall. When adjusting the position of the clamp 5, the shim can deform under the pressure of the clamp 5 and the clamp seat 6, thereby adapting to a position or angle where the upper surface of the clamp 5 is perpendicular to the spindle, better achieving the technical effect of improving processing accuracy.

[0048] In this embodiment, the clamping end moving unit of the cutting and grinding machine tool includes a first direction track device 704 arranged along a first direction, a first direction slider structure 703 slidably engaged with the first direction track device 704, a second direction track device 702 in a second direction on the upper surface of the first direction slider structure 703, and a second direction slider structure 701 slidably engaged with the second direction track device 702 above it. A clamping seat 6 is mounted on the top surface of the second direction slider structure 701. The second direction is perpendicular to the first direction, and both the first and second directions are in a 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 cutting or milling, the workpiece feed speed is stable, thereby improving control accuracy.

[0049] In this embodiment, a clamp motor that drives the clamp 5 to rotate is installed on the clamp base 6, and the clamp motor and the spindle motor output coaxial rotary motion.

[0050] During the cutting process, after the first cutting stroke, the rock sheet rotates 180 degrees around the spindle before the second cutting stroke. For example, when cutting a rock sample, the sample is clamped, and the clamping end moving unit is adjusted to move the sample to a suitable position. The Y-axis cutting length is set to 52.00 mm, the Y-axis feed speed is 0.10 mm / s, and the rotation speed is 3500 r / min. After starting, the cutting blade will rotate at 3500 r / min and travel at a constant speed of 0.10 mm / s along the Y+ axis. After the cutting blade has traveled 26.00 (52 / 2 = 26) mm, it will return to the initial Y-axis position at 10.00 mm / s. During the return process, the cutting blade rotation speed remains unchanged. After returning to the initial Y-axis position, the sample rotates 180 degrees around the main axis, and the cutting blade travels at a constant speed of 0.10 mm / s along the Y+ axis again. After the sample has traveled another 26.0 + Q, the cutting is complete. Then the cutting blade automatically resets to the initial Y-axis position at a reset speed of 10.00 mm / s. During the reset process, the cutting blade still maintains a speed of 3500 r / min. After the reset is complete, the cutting blade stops rotating.

[0051] In this embodiment, the clamp motor on the moving unit at the mounting end, which drives the clamp 5 to rotate, enables the rock slice to rotate 180 degrees around the main shaft after the first cutting stroke, and then perform the second cutting stroke. This cutting method ensures that the sample's cross-section can be completely cut, reducing the contact area between the cutting blade and the rock slice. Furthermore, the overall working space of the machine can be reduced, which is beneficial for reducing the overall size and weight of the machine.

[0052] The cutting process is complete when the spindle rotates 180 degrees and the rock slice travels another 26.0+Q. Q can be 2-8 mm to ensure that the rock slice is completely cut through.

[0053] This embodiment provides a cutting and grinding machine tool for producing rock thin slices, which can both cut rock blocks into rock thin slices and mill the rock thin slices to make their surface roughness meet the test requirements.
