Description

Technical Field

[0001] This utility model relates to the field of rock sample preparation technology, and in particular to an auxiliary device for grinding thin rock sections. Background Technology

[0002] Rock thin section preparation is a common experimental technique in geology and petrology, serving as an important tool for observing and studying the structure, texture, mineral composition, and associated relationships of rocks. To better observe and analyze rocks under a microscope, rock thin sections typically need to be ground to a thickness of only 0.03 mm. First, the rock is cut into sections approximately 3 cm x 2 cm x 0.6 cm in length, width, and thickness using a slicer. One side of the section is then ground smooth on a grinding machine and adhered to a glass slide with uniform dimensions of 76.5 mm x 25.5 mm x 1.2 mm. Once the rock sections are firmly bonded, grinding the adhered sections on the slide is crucial for producing qualified thin sections. Current techniques typically use a grinding machine to grind the rock sections on the slide. A grinding machine usually consists of a frame and a motor mounted on the frame driving a horizontally positioned circular grinding disc. The motor drives the circular grinding disc to rotate rapidly, grinding the slide. For safety reasons, operators are not allowed to wear gloves when grinding thin rock slices attached to a glass slide, as the grinding disc is rotating rapidly during the process. They must hold the slide by hand to grind the rock slices. This method of grinding rock slices by hand has several drawbacks: directly pinching and pressing the slide with the hands can easily cut the operator's fingers due to the edges of the slide; because the slide is thin and difficult to grip, fingers can easily come into contact with the rapidly rotating grinding disc and get abraded; if the slide is accidentally dropped on the rapidly rotating grinding disc, it can easily shatter and scatter, causing injury; because various abrasive materials of different grit sizes are sprinkled onto the grinding disc during grinding, the fingers will be in a wet environment for a long time, which may lead to excessive moisture in the hands, increasing the risk of skin infections, eczema, dermatitis, and other skin diseases; and manual grinding by hand can only grind one rock slice at a time, resulting in low grinding efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an auxiliary device for grinding thin rock sheets, so as to solve the problem that the fingers of workers are easily scratched by the glass slide and abraded by the grinding wheel when grinding thin rock sheets by hand.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an auxiliary device for grinding thin rock sections, comprising an adsorption seat for adsorbing glass slides, a vacuum pump, and a support for supporting the adsorption seat. The adsorption seat includes a horizontally arranged mounting plate and an adsorption plate disposed on the lower surface of the mounting plate. The adsorption plate is provided with adsorption holes, which are connected to the vacuum pump through air pipes for adsorbing glass slides. The support includes a support rod connected to a grinding machine and a connecting rod elastically connected to the support rod. The connecting rod is vertically arranged, with its lower end fixedly connected to the mounting plate and its upper end elastically connected to the support rod through an elastic element.

[0005] In the above scheme, initially, under the elastic force of the elastic element, the adsorption seat is positioned above the grinding disc at a certain distance from the upper surface of the grinding disc. The side of the glass slide without the attached rock sheet is pressed against the adsorption plate. The vacuum pump is run to adsorb the glass slide onto the adsorption plate. By holding the connecting rod and overcoming the elastic force of the elastic element, the adsorption seat is moved downwards so that the rock sheet on the lower surface of the glass slide contacts the rotating grinding disc, thus allowing the rock sheet to be ground. During the grinding process, because the operator's fingers do not directly pinch the glass slide near the grinding disc, the glass slide will not scratch the operator when grinding the rock sheet. The rotating grinding wheel will not injure the operator's fingers. Because the connecting rod is a certain distance from the grinding wheel, the operator's fingers will not be in contact with the sand and water mixture used to grind the rock slabs for a long time. This will prevent the skin on the hands from becoming too wet and increasing the risk of skin infections, eczema, dermatitis and other skin diseases. If the operator accidentally causes the suction seat to detach from their hand during the grinding process, the elasticity of the elastic element will prevent the suction seat from falling and contacting the rotating grinding wheel, and prevent the glass slide with the rock slab attached from being knocked away by the rotating grinding wheel and causing injury.

[0006] Furthermore, the lower surface of the adsorption plate is recessed with a limiting groove adapted to the shape of the glass slide. The depth of the limiting groove is less than half the thickness of the glass slide, and the adsorption hole is disposed on the bottom wall of the limiting groove. The limiting groove limits the glass slide on all four sides, preventing the glass slide from being pushed and sliding off the adsorption plate during the grinding of the rock thin section.

[0007] Furthermore, to ensure the slide is horizontal for easy absorption by the adsorption plate, the auxiliary device also includes a slide pre-positioning seat. The slide pre-positioning seat includes an outer frame with an upper opening and a slide placement plate disposed within the outer frame. The opening of the outer frame is adapted to the shape of the mounting plate so that the mounting plate can be slidably inserted into the outer frame from the open end. The slide placement plate is correspondingly positioned to the adsorption plate. The upper surface of the slide placement plate is recessed with a first groove adapted to the shape of the slide. The first groove contains a second groove corresponding to a thin rock sheet adhered to the slide. The depth of the first groove is less than half the thickness of the slide, and the depth of the second groove is greater than the thickness of the thin rock sheet to be polished adhered to the slide.

[0008] Place the glass slide to be ground, with the rock flakes bonded to it, in the first groove with the rock flakes facing down. Hold the connecting rod and move the mounting plate so that the mounting plate aligns with the opening of the outer frame of the seat and slides into the outer frame. Then, the adsorption plate aligns with the glass slide placement plate so that the upper surface of the glass slide is in contact with the inner bottom wall of the limiting groove on the lower surface of the adsorption plate. Then, start the vacuum pump to adsorb the glass slide with the rock flakes bonded to it onto the adsorption plate. Hold the connecting rod and move the mounting plate to the rotating grinding disc to grind the rock flakes on the glass slide.

[0009] Furthermore, the bottom wall of the limiting groove is recessed with intersecting adsorption grooves, which communicate with the adsorption holes. This design disperses the adsorption force of the vacuum pump, ensuring uniform force on the glass slide and preventing deformation of the glass slide that could lead to uneven thickness of the polished rock slices.

[0010] Furthermore, multiple adsorption plates are evenly distributed on the lower surface of the mounting plate, and multiple glass slide placement plates are correspondingly arranged inside the outer frame of the base. This allows for the simultaneous grinding of multiple thin rock slices in one operation, improving rock grinding efficiency.

[0011] Furthermore, a buffer layer is provided at the bottom of the slide placement plate to buffer the force when the adsorption plate contacts the slide, while ensuring that the upper surface of the slide on each placement plate can be tightly attached to the bottom wall of the upper positioning groove of the corresponding adsorption plate.

[0012] Furthermore, the support rod includes a vertically arranged upright and a horizontally arranged telescopic rod. The lower end of the upright is rotatably connected to the frame of the grinding machine, one end of the telescopic rod is fixedly connected to the upper end of the upright, and the other end of the telescopic rod is fixedly connected to the elastic element. The rotatable upright and the horizontally arranged telescopic rod allow the adsorption seat to be moved freely in the horizontal direction.

[0013] Furthermore, a control switch for controlling the operation of the vacuum pump is provided on the connecting rod.

[0014] Furthermore, the side wall of the outer frame of the seat is provided with a vent hole one that connects the inner cavity of the outer frame of the seat with the outer space of the outer frame of the seat, and the glass slide placement plate is provided with a vent hole two that connects the second groove with the outer space of the placement plate.

[0015] Furthermore, the elastic element includes a vertically arranged spring, the upper end of which is fixedly connected to the telescopic rod, and the lower end of which is fixedly connected to the connecting rod.

[0016] Compared with the existing technology of directly handling and polishing glass slides with both hands, this solution has at least the following advantages:

[0017] 1. This solution effectively prevents the operator's fingers from being scratched by the glass slide;

[0018] 2. This solution effectively prevents the operator's fingers from being injured by the grinding wheel;

[0019] 3. This solution effectively prevents the operator's fingers from becoming excessively moist due to prolonged contact with the sand and water-mixed abrasive on the grinding wheel used to grind thin rock sheets, which can increase the risk of skin infections, eczema, dermatitis, and other skin diseases.

[0020] 4. In this solution, if the operator accidentally causes the adsorption seat to detach from the operator's hand during the grinding process, the spring force can prevent the adsorption seat from falling and contacting the rotating grinding disc, thus preventing the glass slide with the rock sheet attached from being knocked away by the rotating grinding disc and causing injury.

[0021] 5. Using this solution, at least two rock slabs can be ground simultaneously, improving the efficiency of rock slab grinding. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0041] The present invention will be further described below with reference to the accompanying drawings:

[0042] This utility model relates to an auxiliary device for grinding thin rock sheets, such as... Figures 1-6As shown, it includes an adsorption seat 10 for adsorbing a glass slide 50, a vacuum pump 80, a glass slide pre-positioning seat 40 for keeping the glass slide 50 in a horizontal state to facilitate the adsorption seat 10 adsorbing the glass slide 50, and a support member for supporting the adsorption seat 10.

[0043] Combination Figure 1 , Figure 2 As shown, the adsorption base 10 includes a horizontally arranged mounting plate 101 and a plurality of adsorption plates 102 evenly arranged on the lower surface of the mounting plate 101. Both the mounting plate 101 and the adsorption plates 102 are square plates. The adsorption plates 102 are fixedly connected to the lower surface of the mounting plate 101. In this embodiment, a total of three adsorption plates 102 are provided. In other feasible embodiments, other numbers of adsorption plates 102 can be reasonably provided, which will not be elaborated here. Figure 3 , Figure 4 As shown, the lower surface of the adsorption plate 102 is recessed with a limiting groove 1022 that matches the shape of the glass slide 50. The depth of the limiting groove 1022 is less than 1 / 2 the thickness of the glass slide 50. The bottom wall of the limiting groove 1022 is recessed with intersecting adsorption grooves 1023. The adsorption grooves 1023 are distributed on the bottom wall of the limiting groove 1022 within the area covered by the glass slide 50. The adsorption plate 102 is vertically provided with an adsorption hole 1021 that runs through the top and bottom of the adsorption plate 102. The adsorption hole 1021 is provided on the bottom wall of the limiting groove 1022 and communicates with the adsorption grooves 1023.

[0044] like Figure 2 As shown, the slide holder 40 includes an outer frame 401 with an opening at the top and slide placement plates 402 corresponding to the three adsorption plates 102, which are disposed within the outer frame 401. The outer frame 401 is a box with an opening at the top, and the opening of the outer frame 401 is adapted to the shape of the mounting plate 101. A vent hole 4011 is provided in the side wall of the outer frame 401 to connect the inner cavity of the outer frame 401 with the external space of the outer frame 401. When the mounting plate 101 is slidably inserted into the outer frame 401 from the open end, the slide placement plate 402 aligns with the adsorption plate 102. Figure 5 , Figure 6As shown, the upper surface of the slide placement plate 402 is recessed with a first groove 4021 that matches the shape of the slide 50. The bottom wall of the first groove 4021 is recessed downward with a second groove 4022 corresponding to the rock sheet 51 bonded to the slide 50. The depth of the first groove 4021 is less than 1 / 2 the thickness of the slide 50, and the depth of the second groove 4022 is greater than the thickness of the rock sheet 51 to be polished bonded to the slide 50. The placement plate is provided with a second vent hole 4023 that connects the second groove 4022 with the external space of the placement plate. The bottom of the slide placement plate 402 is provided with a buffer layer 403 made of elastic rubber. The buffer layer 403 is used to buffer the force when the adsorption plate 102 contacts the slide 50, and at the same time, it can ensure that the upper surface of the slide 50 on each placement plate can be tightly attached to the bottom wall of the upper limit groove 1022 of the corresponding adsorption plate 102.

[0045] In this embodiment, the vacuum pump 80 is mounted on the connecting rod 22. The vacuum pump 80 is connected to an external power source. A control switch 70 for controlling the operation of the vacuum pump 80 is mounted on the connecting rod 22. The vacuum pump 80 is connected to the adsorption hole 1021 through the air pipe 103. One end of the air pipe 103 is connected to the vacuum pump 80, and the lower end of the air pipe 103 passes through the mounting plate 101 and is sealed and connected to the adsorption hole 1021.

[0046] The support component includes a support rod 21 connected to the grinding mill 60 and a connecting rod 22 elastically connected to the support rod 21. The connecting rod 22 is vertically arranged, with its lower end fixedly connected to the mounting plate 101, and its upper end elastically connected to the support rod 21 via an elastic element 30. Figure 1 As shown, the support rod 21 includes a vertically arranged upright rod 211 and a horizontally arranged telescopic rod 212. A bearing seat 90 is fixedly connected to the outer wall of the frame 602 of the grinding machine 60. The upright rod 211 is vertically arranged, and the lower end of the upright rod 211 is inserted into the bearing seat 90 and rotatably connected to the bearing seat 90. One end of the telescopic rod 212 is fixedly connected to the upper end of the upright rod 211, and the other end of the telescopic rod 212 is fixedly connected to the elastic element 30. Specifically, the elastic element 30 includes a vertically arranged spring. The upper end of the spring is fixedly connected to the end of the telescopic rod 212 away from the upright rod 211, and the lower end of the spring is fixedly connected to the upper end of the connecting rod 22.

[0047] In the initial state of use, under the elastic force of the elastic member 30, the adsorption seat 10 is positioned above the grinding disc 601 and at a certain distance from the upper surface of the grinding disc 601. The glass slide 50 with the adhered rock sheet 51 is placed in the first groove 4021 with the rock sheet 51 facing downwards. Figure 6As shown, by holding the connecting rod 22, the mounting plate 101 is moved so that it aligns with the opening of the outer frame 401 and slides into the outer frame 401. Then, the adsorption plate 102 is aligned with the slide placement plate 402 so that the upper surface of the slide 50 is in contact with the inner bottom wall of the limiting groove 1022 on the lower surface of the adsorption plate 102. Then, by controlling the switch 70 to start the vacuum pump 80, the slide 50 with the attached rock slab 51 can be adsorbed onto the adsorption plate 102. By holding the connecting rod 22, the mounting plate 101 is moved onto the rotating grinding disc 601 to grind the rock slab 51 on the slide 50. After grinding, the vacuum pump 80 is stopped by controlling the switch 70 to remove the slide 50.

[0048] During the grinding process, since the operator's fingers do not directly hold the glass slide 50 close to the grinding disc 601, the glass slide 50 will not scratch the operator's fingers when grinding the rock slab 51, and the rotating grinding disc 601 will not abrade the fingers. Since the connecting rod 22 is a certain distance from the grinding disc 601, the operator's fingers will not be in contact with the sand and water mixed abrasive on the grinding disc 601 for a long time, thus preventing the skin of the hands from becoming excessively moist and increasing the risk of skin infections, eczema, dermatitis and other skin diseases. During the grinding process, if the operator accidentally causes the suction seat 10 to detach from the operator's hand, the elastic force of the elastic element 30 can prevent the suction seat 10 from falling and contacting the rotating grinding disc 601, preventing the glass slide 50 with the rock slab 51 attached from being knocked away by the rotating grinding disc 601 and causing injury.

[0049] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
