Description

Technical Field

[0001] This invention relates to the field of machining tools for mechanical parts, and more specifically to grinding apparatus. Background Technology

[0002] The grinding device includes a grinding head. When in use, the grinding head acts on the surface of the workpiece to grind the surface of the workpiece.

[0003] The grinding head has a grinding shank on top, a mounting plate below the grinding shank, and multiple sets of grinding bodies mounted below the grinding plate. Each set of grinding bodies includes one or more grinding bodies. Each grinding body includes a mounting base, a grinding body frame, and a grinding block. The mounting base is mounted below the mounting plate, and the grinding block is mounted below the mounting base.

[0004] In the existing technology, the coarseness of the grinding block acting on the surface of the workpiece cannot be adjusted. If different grinding blocks with different coarseness are used, the grinding head must be replaced, which is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a grinding device that can automatically change the coarseness of the grinding head during the grinding process, thereby meeting certain usage requirements.

[0006] The technical solution adopted by this invention is as follows: a grinding device includes a grinding head, a grinding handle on top of the grinding head, a mounting plate below the grinding handle, and multiple sets of grinding bodies mounted below the grinding plate. Each set of grinding bodies includes one or more grinding bodies. Each grinding body includes a mounting base, a grinding body frame, and a grinding block. The mounting base is mounted below the mounting plate. The device is characterized by: a vertically oriented sliding groove below the mounting base, in which a spring is installed; a sliding head mounted in the sliding groove on top of the grinding body frame; and the grinding block mounted below the grinding body frame. A first electromagnet A connected to a control device is also installed in the mounting base, and a first electromagnet B connected to a control device is installed inside the sliding head. The grinding blocks in different sets of grinding bodies have different roughnesses. Adjusting the force intensity of the first electromagnet A and the first electromagnet B in different sets of grinding bodies can adjust the degree of contact between the grinding blocks and the grinding surface in different sets of grinding bodies.

[0007] Furthermore, when each group of grinding media contains multiple grinding media, these multiple grinding media are arranged in an array around the mounting plate.

[0008] Furthermore, the control device has a first signal transceiver and a second signal transceiver that matches the first signal transceiver.

[0009] Furthermore, a suction cup is connected below the mounting plate via a connecting rod. The connecting rod includes an upper section and a lower section, which are connected by a rotating sleeve.

[0010] Furthermore, a top spring is also installed inside the rotating sleeve, which presses against the lower end of the upper section of the connecting rod and the upper end of the lower section of the connecting rod.

[0011] Furthermore, a second electromagnet A, connected to a control device, is installed inside the upper section of the connecting rod, and a second electromagnet B, also connected to a control device, is installed inside the lower section of the connecting rod. Adjusting the force intensity of the second electromagnet A and the second electromagnet B can adjust the tightness of the contact between the grinding block and the workpiece.

[0012] Furthermore, the grinding head is a grinding roller or a flat grinding disc.

[0013] Furthermore, the control device is a PLC control device, which has multiple grinding modes. According to the roughness of the grinding blocks, the grinding body groups with different roughness from coarse to fine are the first grinding body group, the second grinding body group, and the third grinding body group. One grinding mode is to turn on the first grinding body group, the second grinding body group, and the third grinding body group in sequence. When one grinding body group is turned on, the other grinding body groups are turned off. Turning on a grinding body group means reducing the attractive force of the first A electromagnet and the first B electromagnet in this grinding body group or increasing the repulsive force, so that the grinding blocks in this grinding body group can better contact the workpiece for grinding.

[0014] Furthermore, when a grinding body assembly is used to grind a workpiece, it is a grinding stage. The grinding mode also includes: in a grinding stage, the attractive force between the second A electromagnet and the second B electromagnet gradually decreases or the repulsive force gradually increases.

[0015] Furthermore, the device also includes a grinder, on which the grinding head is mounted.

[0016] The beneficial effects of this invention are: such a grinding device can automatically change the working state of grinding heads with different coarseness during the grinding process, that is, change the working state of the grinding head, which meets some usage requirements.

Detailed Implementation

[0022] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0023] As shown in the figure, a grinding device includes a grinding head 1, a grinding handle 11 on top of the grinding head, a mounting plate 12 below the grinding handle, and multiple sets of grinding bodies mounted below the grinding plate. Each set of grinding bodies includes one or more grinding bodies 13. Each grinding body includes a mounting base 131, a grinding body frame 132, and a grinding block 133. The mounting base is mounted below the mounting plate. The device is characterized by having a vertically oriented sliding groove 1311 below the mounting base, within which a spring 134 is installed. The grinding body frame has a mounting... The sliding head 1321 is installed in the chute, and the grinding block 133 is installed below the grinding body frame. A first A electromagnet 1351 connected to the control device 14 is also installed in the mounting base, and a first B electromagnet 1352 connected to the control device is also installed in the sliding head. The grinding blocks in different grinding body groups have different roughnesses. By adjusting the force intensity of the first A electromagnet and the first B electromagnet in different grinding body groups, the degree of contact between the grinding blocks and the grinding surface in different grinding body groups can be adjusted.

[0024] The above-described configuration of this invention allows for the adjustment of grinding blocks with different roughnesses. Specific adjustments can be made via a control device. For example, if a coarser grinding block is to be used, it can be moved downwards. This can be achieved by activating the first A electromagnet and the first B electromagnet, increasing the repulsive force between them or decreasing the attractive force. Since the sliding head 1321 is installed in the groove, the grinding block can be moved upwards. During adjustment, only the control device needs to be adjusted; the grinding head does not need to be replaced, thus achieving the purpose of this invention.

[0025] The grinding blocks in the different grinding media groups have different roughnesses. In each embodiment, the grinding blocks are 100 grit, 150 grit, and 200 grit, respectively.

[0026] Furthermore, when each group of grinding media contains multiple grinding media, these multiple grinding media are arranged in an array around the mounting plate.

[0027] The above-mentioned settings of the present invention can ensure better stability when using this grinding media.

[0028] Furthermore, the control device has a first signal transceiver and a second signal transceiver that matches the first signal transceiver.

[0029] The above-mentioned settings of the present invention can be switched at any time during the grinding process to achieve seamless connection, and can also be remotely controlled.

[0030] Furthermore, a suction cup 16 is connected below the mounting plate via a connecting rod 15. The connecting rod includes an upper section 151 and a lower section 152, and the upper and lower sections are connected by a rotating sleeve 153.

[0031] The above-mentioned configuration of the present invention can also achieve positioning of the grinding part, that is, the grinding part is around the suction cup, and the suction cup can be, for example, a hemispherical rubber cup; the upper section and the lower section of the connecting rod are connected by a rotating sleeve 153, which ensures that the rubber cup is fixed during use and the mounting plate can rotate.

[0032] Furthermore, a top spring 154 is also installed inside the rotating sleeve, which presses against the lower end of the upper section of the connecting rod and the upper end of the lower section of the connecting rod.

[0033] Furthermore, a second electromagnet 1551 connected to a control device is installed in the upper section of the connecting rod, and a second electromagnet 1552 connected to a control device is installed in the lower section of the connecting rod; adjusting the force intensity of the second electromagnets 1551 and 1552 can adjust the tightness of the contact between the grinding block and the workpiece.

[0034] The above-mentioned settings of the present invention can also adjust the distance between the mounting plate and the workpiece grinding surface, that is, adjust the force exerted by the grinding block on the workpiece grinding surface.

[0035] Furthermore, the control device has a first signal transceiver and a second signal transceiver that matches the first signal transceiver.

[0036] Furthermore, the grinding head is a grinding roller or a flat grinding disc.

[0037] Furthermore, the control device is a PLC control device, which has multiple grinding modes. According to the roughness of the grinding blocks, the grinding body groups with different roughness from coarse to fine are the first grinding body group, the second grinding body group, and the third grinding body group. One grinding mode is to turn on the first grinding body group, the second grinding body group, and the third grinding body group in sequence. When one grinding body group is turned on, the other grinding body groups are turned off. Turning on a grinding body group means reducing the attractive force of the first A electromagnet and the first B electromagnet in this grinding body group or increasing the repulsive force, so that the grinding blocks in this grinding body group can better contact the workpiece for grinding.

[0038] The above-mentioned settings of the present invention can also automatically complete the entire process of grinding a workpiece from coarse to fine, making it more convenient to use and with a higher degree of automation.

[0039] Furthermore, when a grinding body assembly is used to grind a workpiece, it is a grinding stage. The grinding mode also includes: in a grinding stage, the attractive force between the second A electromagnet and the second B electromagnet gradually decreases or the repulsive force gradually increases.

[0040] The above-mentioned settings of the present invention can also achieve a gradual reduction in the pressing pressure on the workpiece during a certain stage, resulting in a smoother grinding surface.

[0041] Furthermore, the device also includes a grinder 2, on which the grinding head is mounted.

[0042] For example, the grinding machine has a grinding machine frame 21, on which a grinding motor 22 is mounted. The grinding motor has a mounting sleeve 23 for mounting a grinding head. The grinding machine frame has a grinding station 24. The grinding head faces the grinding station, which can grind the workpiece.

[0043] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
