Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to an ore surface grinding device. Background Art

[0002] Diamond is a mineral composed of carbon. It is an allotrope of graphite with a chemical formula of C. It is also the original form of common diamond. Diamond is the hardest substance that exists naturally in nature. Graphite can form artificial diamond under high temperature and high pressure. When processing diamond, it is necessary to perform rough grinding to improve its surface quality.

[0003] Due to the high hardness of diamond, greater pressure needs to be applied to it during grinding to ensure the quality and efficiency of grinding. Therefore, the following problems exist in the grinding process: 1. The greater grinding pressure will cause greater force on one side of the grinding disc, and the spindle of the grinding disc will be subjected to greater deflection force, which is easy to deform and damage the grinding device; 2. During the grinding process, the diamond usually slides on the grinding disc along the radial direction of the grinding disc for grinding. The closer the diamond is to the edge of the grinding disc, the greater the torque between the diamond grinding position and the spindle, and the grinding disc is prone to deformation.

[0031] like Figures 1 to 7 As shown, an ore surface grinding device provided by an embodiment of the present invention includes a frame 100, a spindle 101, a grinding disc 102, a pressurizing mechanism, a clamping mechanism and a supporting mechanism. The frame 100 is horizontally arranged, and the spindle 101 is rotatably arranged on the frame 100 around its own axis, and the axis of the spindle 101 extends in a vertical direction.

[0032] The pressure mechanism includes a horizontal plate 201, a pressure roller, a first pressure regulating assembly and a second pressure regulating assembly. The horizontal plate 201 is slidably disposed on the frame 100 along one radial direction of the grinding disc 102. The sliding direction of the horizontal plate 201 is the first direction (i.e. Figure 1 In the left and right directions), the pressure roller is slidably arranged on the frame 100 along the vertical direction and the first direction respectively, and the pressure roller is slidably connected to the upper surface of the grinding disc 102, the first pressure regulating component and the second pressure regulating component are both arranged on the frame 100, the first pressure regulating component adjusts the pressure of the pressure roller on the grinding disc 102 by sliding the transverse plate 201 on the frame 100, and the second pressure regulating component adjusts the position of the pressure roller on the grinding disc 102 by sliding the transverse plate 201 on the frame 100.

[0033] The clamping mechanism is installed on the horizontal plate 201. The clamping mechanism is used to clamp the ore and place the ore on the grinding disc 102. The position of the ore on the grinding disc 102, the axis of the mandrel 101 and the connection position between the pressure roller and the grinding disc 102 are all located on the same straight line, and the mandrel 101 is located between the ore and the pressure roller.

[0034] The support mechanism is installed on the spindle 101 , and the support mechanism is located below the grinding disc 102 , and is used to buffer the grinding disc 102 when the grinding disc 102 slides along the spindle 101 .

[0035] When the ore moves away from the spindle 101, the pressure between the grinding disc 102 and the ore remains unchanged, the pressure between the pressure roller and the grinding disc 102 increases, and the distance between the grinding disc 102 and the supporting mechanism decreases.

[0036] The ore to be ground is mounted on the clamping mechanism, and the clamping mechanism brings the ore into contact with the grinding disc 102, and the grinding disc 102 rotates to grind the ore. By arranging a pressure roller on one side of the spindle 101, when the ore is being ground, the grinding discs 102 on both sides of the spindle 101 are simultaneously subjected to pressure with the spindle 101 as the center, thereby reducing the deflection force of the spindle 101 caused by the pressure between the ore and the grinding disc 102, slowing down the deformation of the spindle 101, and increasing the service life of the spindle 101. At the same time, the pressure roller can also The abrasive grains added to the surface of the grinding disc 102 are pressed into the grinding disc 102 to improve the grinding quality; the grinding disc 102 is slidably arranged relative to the spindle 101 along the axial direction of the spindle 101 to avoid the change of the torque between the spindle 101 and the ore affecting the stability of the grinding disc 102, thereby improving the service life of the grinding disc 102, and setting a second pressure regulating component to balance the forces on both sides of the grinding disc 10, thereby reducing the friction generated when the grinding disc 102 slides along the spindle 101, so that the sliding of the grinding disc 102 is smoother.

[0037] In this embodiment, a support plate 103 is fixedly installed on the frame 100, and a second slide groove 213 is provided on the support plate 103. The pressure roller includes a slide bar 212, a mounting frame 203, a rotating drum 202 and a telescopic rod 204. The slide bar 212 is slidably arranged in the second slide groove 213 along the vertical direction and the first direction. The mounting frame 203 is fixedly installed on the bottom end of the slide bar 212. The rotating drum 202 is rotatably arranged on the mounting frame 203. The axis of the rotating drum 202 extends along the radial direction of the grinding disc 102. The rotating drum 202 abuts against the grinding disc 102. There is friction between the rotating drum 202 and the grinding disc 102, so that the rotating drum 202 cannot slide relative to the grinding disc 102 in the first direction. The telescopic rod 204 is slidably arranged on the support plate 103 along the vertical direction, and the telescopic rod 2 04 passes through the support plate 103, a third slide groove 214 is provided on the mounting frame 203, the bottom end of the telescopic rod 204 is slidably arranged in the third slide groove 214 along the vertical direction, a baffle 205 is installed on the telescopic rod 204, the baffle 205 is located below the support plate 103, a spring 206 is sleeved on the telescopic rod 204, both ends of the spring 206 are slidably connected with the baffle 205 and the mounting frame 203 respectively, the baffle 205 and the support plate 103 are abutted under the action of the spring 206, the spring 206 is in a compressed state, there is pressure between the rotating drum 202 and the grinding disc 102, the length of the rotating drum 202 is adapted to the radius of the grinding disc 102, the rotating drum 202 can squeeze the abrasive particles sprinkled on the grinding disc 102 into the gap on the grinding disc 102, thereby improving the grinding quality of the ore.

[0038] In this embodiment, the first pressure regulating assembly includes a first wedge plate 207 and a second wedge plate 208. The first wedge plate 207 and the second wedge plate 208 are both provided with inclined surfaces. The first wedge plate 207 is fixedly mounted on the cross plate 201, and the second wedge plate 208 is slidably arranged on the support plate 103 along the second direction. The second wedge plate 208 contacts the baffle plate 205, and the second wedge plate 208 is located between the support plate 103 and the baffle plate 205. The second direction is perpendicular to the sliding direction of the cross plate 201 in the same horizontal plane. The inclined surface of the first wedge plate 207 faces the direction in which the clamping mechanism drives the ore away from the spindle 101. The first wedge plate 207 can contact one end of the second wedge plate 208 through its inclined surface. The inclined surface of the second wedge plate 208 faces downward, and the baffle plate 205 is in contact with the second wedge plate 20 8 is provided with an inclined surface matched with the second wedge plate 208, and the inclined surface of the second wedge plate 208 faces away from the first wedge plate 207. When the second wedge plate 208 slides on the support plate 103 along the second direction, it pushes the baffle plate 205 through its own inclined surface to drive the telescopic part to slide, thereby changing the elastic potential energy of the spring 206, and then changing the pressure between the pressure roller and the grinding disc 102. After the first wedge plate 207 no longer applies a force to the second wedge plate 208, the second wedge plate 208 slides under the pressure of the spring 206 and always fits with the first wedge plate 207. The pressure of the pressure roller and the ore on the grinding disc 102 makes the grinding disc 102 located in the horizontal plane, ensuring the smoothness of the sliding of the grinding disc 102 along the spindle 101 and avoiding the tilting of the spindle 101.

[0039] In this embodiment, a first sliding groove 209 is opened on the inclined surface of the second wedge plate 208, and the first sliding groove 209 passes through the second wedge plate 208. The telescopic part of the telescopic rod 204 is slidably set in the first sliding groove 209. The force applied by the second wedge plate 208 to the baffle plate 205 is evenly distributed to avoid obstruction of movement between the second wedge plate 208 and the baffle plate 205.

[0040] In this embodiment, the second pressure regulating assembly includes a mounting plate 210, a first hydraulic cylinder 211, a second hydraulic cylinder and a push rod 215. The mounting plate 210 is fixedly mounted on the frame 100. The first hydraulic cylinder 211 is horizontally mounted on the frame 100, and one end of the first hydraulic cylinder 211 is connected to the cross plate 201. When the cross plate 201 slides on the frame 100, it can push the first hydraulic cylinder 211 to extend and retract. The second hydraulic cylinder is fixedly mounted on the mounting plate 210. The first hydraulic cylinder 211 and the second hydraulic cylinder are connected by an oil pipe. When the cross plate 201 drives the ore away from the spindle 101, the hydraulic oil in the first hydraulic cylinder 211 is transported to the second hydraulic cylinder through the oil pipe. The contraction of the second hydraulic cylinder drives the push rod 215 to move in the direction away from the spindle 101. The push rod 21 The push rod 215 is slidably arranged on the mounting plate 210 along the first direction, and the push rod 215 is connected to the second hydraulic cylinder. The push rod 215 is slidably connected to the slide bar 212, and there is friction between the push rod 215 and the slide bar 212. When the push rod 215 slides in the first direction, the friction between the push rod 215 and the slide bar 212 can drive the rotating drum 202 to move. The friction between the rotating drum 202 and the grinding disc 102 is greater than the friction between the push rod 215 and the slide bar 212. The rotating drum 202 provides a force opposite to the sliding direction of the ore on the grinding disc 102 to the grinding disc 102 through the friction between the rotating drum 202 and the grinding disc 102, so that the friction between the grinding disc 102 and the spindle 101 is balanced, and the grinding disc 102 slides on the spindle 101 more smoothly.

[0041] In this embodiment, the supporting mechanism includes a fixed disk 401 and an airbag 402.

[0046] The working principle and working method of an ore surface grinding device provided in this embodiment are as follows:

[0047] (Take diamond as an example, ore is replaced by diamond in the following text) First, the diamond is fixed to the end of the output shaft of the first motor 302 by yellow glue, and then the third motor 104 is started. The third motor 104 drives the third rotating wheel 105 to rotate. The third rotating wheel 105 drives the fourth rotating wheel 106 to rotate through the second belt 107. The fourth rotating wheel 106 drives the spindle 101 to rotate. The rotation of the spindle 101 drives the grinding disc 102 to rotate. Then the second motor 303 is started. The second motor 303 drives the first rotating wheel 304 to rotate. The first rotating wheel 304 drives the second rotating wheel 305 to rotate on the positioning plate 301 through the first belt 306. The second rotating wheel 305 drives the output shaft of the first motor 302 to approach the grinding disc 102 through the connecting frame 308 and the sleeve 307 until the diamond contacts the grinding disc 102, so that the grinding disc 102 grinds the diamond.

[0048] Then the fourth motor 109 is started, and the fourth motor 109 drives the gear to rotate. The gear drives the horizontal plate 201 to slide on the slider 108 by meshing with the horizontal plate 201. After sliding, the horizontal plate 201 can drive the positioning plate 301 to move, and the positioning plate 301 can drive the diamond to slide on the grinding disk 102. During the diamond grinding process, the first motor 302 is started, and the first motor 302 drives the diamond to rotate, thereby changing the grinding position of the diamond on the grinding disk 102.

[0049] During the rotation of the spindle 101, the spindle 101 drives the fixed disk 401 to rotate. When the cross plate 201 drives the positioning plate 301 to move away from the spindle 101, the abutment pressure between the first wedge plate 207 and the second wedge plate 208 increases. The first wedge plate 207 pushes the second wedge plate 208 to slide on the support plate 103 through its inclined surface. When the second wedge plate 208 slides, it pushes the baffle plate 205 downward through its own inclined surface. The baffle plate 205 compresses the spring 206, and the spring 206 applies pressure to the mounting frame 203. The mounting frame 203 can apply pressure to the grinding disk 102 through the rotating drum 202. Conversely, the cross plate 201 drives the positioning plate 301 to move towards the spindle 101, and the pressure between the rotating drum 202 and the grinding disk 102 decreases.

[0050] At the same time, when the cross plate 201 drives the positioning plate 301 to move away from the spindle 101, the cross plate 201 pushes the first hydraulic cylinder 211, and the hydraulic oil in the first hydraulic cylinder 211 is transported to the second hydraulic cylinder through the oil pipe. The second hydraulic cylinder drives the push rod 215 to move away from the spindle 101. The push rod 215 drives the slide bar 212 to move away from the spindle 101 through the friction between the push rod 215 and the slide bar 212. The slide bar 212 drives the rotating drum 202 to apply a force on the grinding disc 102 away from the spindle 101 to offset the force generated by friction when the diamond moves from the position of the spindle 101 to the edge of the grinding disc 102 on the grinding disc 102, thereby avoiding an increase in the contact pressure between the grinding disc 102 and the spindle 101, facilitating the sliding of the grinding disc 102 on the spindle 101, and thereby reducing the deformation of the grinding disc 102.

[0051] When the diamond moves to the edge of the grinding disc 102, the fourth motor 109 reverses to make the horizontal plate 201 slide in the opposite direction, driving the diamond to move toward the center axis 101. The diamond continuously changes its contact position with the grinding disc 102 under the rotation of the first motor 302 until the grinding is completed.

[0052] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
