[0002] When processing a hollow pressure transmission block for artificial diamond, it is necessary to grind the six surfaces of the block of the hollow pressure transmission block to obtain a hollow pressure transmission block with smaller dimensional tolerance, smaller shape and position tolerance and higher surface quality. In the prior art, the block is directly processed automatically by a grinding mechanism set on a workbench, but when the block is ground, very serious dust pollution will be generated, causing the operator to inhale dust when taking out the processed hollow pressure transmission block from the machine tool, standing near the machine tool waiting for the grinding mechanism to process the hollow pressure transmission block, and placing the next hollow pressure transmission block to be processed on the machine tool, which will harm the life and health of the operator. Utility Model Content

[0003] The purpose of the utility model is to provide a grinding device to solve the technical problem that the grinding mechanism in the prior art will generate very serious dust pollution when automatically processing a block, causing the operator to inhale dust when taking out the processed hollow pressure transmission block from the machine tool, standing near the machine tool waiting for the grinding mechanism to process the hollow pressure transmission block, and placing the next hollow pressure transmission block to be processed on the machine tool, thereby damaging the life and health of the operator.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the grinding device provided by the utility model is:

[0005] A grinding device comprises a workbench and a grinding mechanism arranged on the workbench. A dust cover is provided on the workbench to prevent dust generated by the grinding mechanism from escaping to the outside. The grinding device also comprises a dust suction structure. The dust suction structure comprises a dust suction port connected to the internal space of the dust cover and a dust outlet connected to the external space of the dust cover. The dust suction port and the dust outlet are connected to allow dust in the dust cover to be discharged from the dust cover. A connecting structure for connecting a dust treatment system is provided on the dust outlet.

[0006] Beneficial effects are as follows: the utility model is an improved invention. A dust cover is provided on the workbench to prevent dust generated when grinding the workpiece to be processed from escaping to the outside, thereby protecting the health of the operator; at the same time, a dust suction structure is provided to suck away the dust in the dust cover, thereby preventing the operator from opening the dust cover when he wants to take or put the workpiece, and the dust adhering to the inner surface of the dust cover or the grinding mechanism becomes floating dust under the action of wind, causing the operator to inhale the dust, thereby endangering the life and health of the operator. When in use, the operator opens the dust cover and places the workpiece to be processed on the grinding mechanism; then closes the dust cover, opens the grinding mechanism and the dust suction structure, and the dust generated when the workpiece to be processed is sucked away through the dust cover and the dust suction structure. By providing a connecting structure at the dust suction port, the sucked dust can be discharged from the dust outlet to the dust treatment system, so that the dust coming out of the dust outlet is prevented from being sprayed near the operator, thereby protecting the operator standing near the grinding device; finally, close the grinding mechanism and the dust suction structure, open the dust cover, and take out the processed workpiece.

[0007] Furthermore, the dust suction structure also includes a first dust suction hood for covering the grinding disc of the grinding mechanism to absorb floating dust during the grinding process, and the air outlet of the first dust suction hood is connected to the dust suction port.

[0008] The beneficial effect is that by providing the first dust hood, the lighter floating dust generated during the grinding process can be better able to reach the dust suction port, thereby improving the dust suction efficiency of the dust suction structure.

[0009] Furthermore, the dust suction structure also includes a second dust suction hood for being arranged under the grinding disc of the grinding mechanism to absorb dust falling under the workpiece to be processed, and the air outlet of the second dust suction hood is connected to the dust suction port.

[0010] The beneficial effect is that by setting the second dust hood, the heavier dust generated during the grinding process and sinking below the workpiece to be processed can better reach the dust suction port, thereby improving the dust suction efficiency of the dust suction structure.

[0011] Furthermore, the dust suction structure also includes a dust suction duct, which includes a suction section arranged in the dust cover and a discharge section extending from the dust cover, the dust suction port is arranged on the suction section, and the dust outlet is arranged on the discharge section.

[0012] The beneficial effects are: by setting up a dust suction duct, the dust suction port and the dust outlet can be easily connected, and the dust suction port can also be set at different positions in the dust cover, so that the dust in the dust cover can be conveniently discharged outside the dust cover; the position of the dust outlet can also be changed through the duct, and the dust outlet can be conveniently connected to the dust treatment system.

[0013] Furthermore, at least two grinding mechanisms are arranged at intervals, a conveyor belt for conveying the workpiece to be processed is arranged between each grinding mechanism, and a rotating mechanism for rotating the workpiece to be processed is arranged between adjacent grinding mechanisms so that different grinding mechanisms grind different surfaces of the workpiece to be processed.

[0014] The beneficial effect is that by setting at least two grinding mechanisms and a rotating mechanism, the grinding mechanism can process multiple surfaces of the workpiece to be processed at one time, thereby improving the processing efficiency of the grinding mechanism. For example, when the grinding device has only one grinding mechanism, one surface of a hexahedron can be processed at one time, which requires six processing times; and when the grinding device has two grinding mechanisms and a rotating mechanism, two surfaces of the same hexahedron can be processed at one time, which requires only three processing times.

[0015] Furthermore, the grinding mechanisms are provided with six, including two top grinding mechanisms and four side grinding mechanisms, and the rotating mechanism includes a vertical rotating mechanism located between the two top grinding mechanisms, so that the two top grinding mechanisms are respectively used to grind the top surface and the bottom surface of the workpiece to be processed; a horizontal rotating mechanism is provided between two adjacent side grinding mechanisms, so that the four side grinding mechanisms are respectively used to grind the four side surfaces of the workpiece to be processed.

[0016] The beneficial effect is: by setting two top grinding mechanisms and four side grinding mechanisms, and setting corresponding vertical rotation mechanisms and horizontal rotation mechanisms, all surfaces of the hexahedral workpiece to be processed can be processed at one time, reducing the number of times the operator opens and closes the dust cover, and improving the processing efficiency of the grinding device.

[0017] Furthermore, the grinding device also includes a conveyor belt, a feed conveyor belt and a discharge conveyor belt located on the workbench. The feed conveyor belt is used to convey the workpiece to be processed to the conveyor belt, the conveyor belt is used to convey the workpiece to be processed to the grinding mechanism, and convey the processed workpiece from the grinding mechanism to the discharge conveyor belt, and the discharge conveyor belt is used to transfer the processed workpiece out of the dust cover; an avoidance opening is opened on the dust cover, and one end of the feed conveyor belt and the discharge conveyor belt extend from the avoidance opening of the dust cover to facilitate the operator to take and place the workpiece outside the dust cover.

[0018] The beneficial effect is that the feed conveyor belt and the discharge conveyor belt enable the operator to take and place the workpiece without opening the dust cover, thereby reducing the operation steps of opening and closing the dust cover, saving time, and improving the processing efficiency of the grinding device.

[0019] Furthermore, the workbench is also provided with a mechanical arm for moving the workpiece to be processed on the feed conveyor belt to the conveyor belt, and / or moving the workpiece that has been processed on the conveyor belt to the discharge conveyor belt.

[0020] The beneficial effect is that the workpiece can be conveniently transferred on the feed conveyor belt, the conveyor belt and the discharge conveyor belt through the robot arm, so that the shape of the conveyor belt is not restricted by the feed conveyor belt and the discharge conveyor belt, and thus the arrangement of multiple grinding mechanisms is not restricted.

[0021] Furthermore, the feed conveyor belt and the discharge conveyor belt are both arranged at one end of the workbench.

[0022] The beneficial effect is that by arranging both the feed conveyor belt and the discharge conveyor belt at one end of the grinding mechanism, only one operator is required to complete the work of taking and placing the workpiece, thus saving labor costs.

[0023] Furthermore, the workbench includes a frame and a bearing plate connected to the frame and used for bearing the grinding mechanism, the dust cover is simultaneously arranged above the bearing plate and around the sides of the frame, and the dust suction port is arranged below the bearing plate.

[0024] The beneficial effect is that the dust suction port is arranged below the carrying plate, so that the dust generated by the workpiece being ground above the carrying plate can naturally fall to the dust suction port. BRIEF DESCRIPTION OF THE DRAWINGS
