Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, and more specifically to a grinding device for machining a motor spindle. Background Art

[0002] The motor spindle refers to the rotating shaft installed on the motor. It is used to support and rotate the motor's rotor and transmit power. The motor spindle is usually made of high-quality metals, such as steel or aluminum alloy, and is precision machined to ensure balance and stability. The design of the spindle depends on the type and purpose of the motor to ensure that it can withstand the expected load and speed. In industrial and mechanical applications, the design and material selection of the spindle are crucial to the performance and life of the motor. Therefore, the production quality requirements for the motor spindle are high. Therefore, in order to improve the surface quality of the spindle during the spindle production process, the surface of the spindle needs to be polished.

[0003] However, the currently available grinding device will peel off tiny particles on the surface of the spindle during the grinding process, and the peeled particles will be mixed with debris of the abrasive material and residues of the lubricant to form dust. The generation of this dust may have a certain impact on the working environment and the health of the operator. In addition, when the motor spindle is ground, it needs to be clamped and fixed first, and the transmission clamping device cannot accurately clamp at the center position of the spindle, which may cause the grinding spindle to deviate during grinding, thereby affecting the quality of the spindle grinding. In addition, the structure of the traditional spindle grinding device is relatively complicated, which leads to an increase in the cost of device maintenance and repair, which is very inconvenient.

The adjusting screw 12 is movably sleeved in an internal position of the adjusting support leg 1302.

[0038] In this embodiment, by adjusting the screw rod 12 and moving the slide rail 13, it is beneficial to evenly grind the surface of the clamped motor spindle body 7, while ensuring that dust is blocked during grinding.

[0042] In the present embodiment: through the mounting plate 20, the rotating fan 21, the filter screen 22, and the filter through hole 2201, the rotating fan 21 inside the mounting plate 20 is facilitated to rotate, so that the air inside the second dust removal mechanism 16 is discharged, thereby forming a negative pressure inside the second dust removal mechanism 16, so that the second dust removal mechanism 16 absorbs the dust through the dust suction hose 6 into the filter screen 22 for filtering and collection, thereby preventing the dust from dispersing and affecting the environment and the staff.

[0043] Reference Figure 8 As shown, the electromagnetic telescopic assembly 3 includes a telescopic tube 301, a telescopic slot 302 is opened inside the telescopic tube 301, an electromagnetic plate 24 is fixedly connected to the top position inside the telescopic slot 302, a telescopic shaft 303 is movably sleeved inside the telescopic slot 302, and one end of the telescopic shaft 303 inside the telescopic slot 302 is fixedly connected to a magnetic block body 304.

[0047] The working principle of the present invention is as follows: first, when in use, the power supply assembly 2 is turned on so that the electromagnetic plate 24 inside the telescopic groove 302 is energized to generate magnetism, and then the magnetic block body 304 on the top of the telescopic shaft 303 is adsorbed through the electromagnetic plate 24, so that the telescopic shaft 303 drives the first dustproof box 4 to rise close to the telescopic tube 301, and then the motor spindle body 7 to be polished is placed in the arc-shaped limit groove 802 position opened in the second dustproof box 8. At this time, the polishing block 23 inside the second dustproof groove 801 and the arc-shaped limit groove 802 support the motor spindle body 7, and then the second clamping assembly 14 and the first clamping assembly 9 are rotated respectively, and then the second clamping assembly 14 drives the clamping screw 1401 to rotate and drives the clamping gasket 1402 to the motor spindle body. When the second clamping assembly 14 and the first clamping assembly 9 clamp and fix the motor spindle body 7, the power supply assembly 2 is turned off at this time so that the first dustproof box 4 drives the telescopic shaft 303 to approach the top of the second dustproof box 8 due to gravity. At this time, the columnar docking rod 403 at the bottom of the first dustproof box 4 enters the circular docking hole 803 opened in the second dustproof box 8. At this time, the grinding block 23 inside the first dustproof box 4 and the first dustproof box 4 sleeve the motor spindle body 7 into the internal position of the first dustproof box 4 and the second dustproof box 8, and then pull out the limit rod 15, so that the limit rod 15 is away from the internal position of the limit column groove 104 and the movable shaft 19, and then turn on the second dust removal mechanism 16 and the first dust removal mechanism 5, and then turn on the grinding. The grinding motor 10 and the regulating motor 11 make the grinding motor 10 drive the micro gear 18 to rotate, and then the micro gear 18 drives the mutually meshing transmission gear 1701 to rotate, at this time the transmission gear 1701 drives the transmission shaft 17 to rotate, and then the rotation of the transmission shaft 17 drives the first clamping assembly 9 and the motor spindle body 7 clamped by the first clamping assembly 9 and the second clamping assembly 14 to rotate, and then the rotation of the motor spindle body 7 makes the grinding block 23 grind the surface of the motor spindle body 7, and then the dust generated by the grinding enters the first dustproof groove 401 and the second dustproof groove 801, and then due to the operation of the second dust removal mechanism 16 and the first dust removal mechanism 5, the rotating fan 21 inside the mounting plate 20 will be the second dust removal mechanism 16 and the air inside the first dust removal mechanism 5 is discharged, and then a negative pressure is formed inside the second dust removal mechanism 16, so that the dust inside the first dust box 4 and the second dust box 8 enters the dust suction hose 6 through the first dust suction hole 402 and the second dust suction hole 804, and then enters the second dust removal mechanism 16 through the dust suction hose 6, and then blocks the filter screen 22 inside the second dust removal mechanism 16, so that the dust is intercepted and collected by the filter screen 22, and then the operation of the adjustment motor 11 drives the adjustment screw 12 and the limiting round block 1201 to rotate inside the adjustment support leg 1302 and the grinding box 1. At this time, the rotation of the adjustment screw 12 drives the adjustment support leg 1302 and the moving slider 1301 to slide inside the moving slide groove 103.At this time, the sliding of the movable slide rail 13 drives the second dustproof box 8 and the first dustproof box 4 to move, and when the first dustproof box 4 moves, it drives the electromagnetic telescopic component 3 and the power supply component 2 to slide inside the rectangular slide groove 102, so that the grinding block 23 inside the first dustproof box 4 and the second dustproof box 8 evenly grinds the surface of the motor spindle body 7, and because the device itself is driven by mechanical operation, the overall structure of the device is simple, reducing the subsequent maintenance cost expenditure of the device.
