Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and more specifically, to a grinding wheel that is easy to assemble and disassemble. Background Technology

[0002] In the field of machining, grinding wheels are the core tool for grinding and polishing the surfaces of metal and non-metal parts. During grinding, the abrasive grains on the surface of the grinding wheel rub intensely against the parts, converting a large amount of mechanical energy into heat energy, causing a sharp rise in the temperature of the processing area. When the temperature exceeds a certain threshold, it will cause thermal deformation of the workpiece surface material, reducing machining accuracy and even causing changes in the metallographic structure, affecting the mechanical properties of the parts. On the other hand, high temperatures will accelerate the wear and shedding of the grinding wheel abrasive grains, shortening the service life of the grinding wheel and increasing production costs. In the processing of parts such as aero-engine blades and precision molds, due to the special materials (such as titanium alloys and high-temperature alloys) or complex structures of the workpieces, directly spraying coolant on the surface can easily lead to material corrosion, water stains, or coolant seepage into the workpiece, causing potential problems for subsequent use. In addition, in the processing of precision parts such as electronic components and optical glass, the use of coolant may contaminate the product surface, affecting its optical or electrical performance. Currently, traditional grinding wheel heat dissipation mainly relies on direct external coolant cooling, but this method is not suitable for the above-mentioned conditions where coolant use is limited. In view of this, we propose a grinding wheel that is easy to disassemble and assemble. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a grinding wheel that is easy to disassemble and assemble, so as to solve the technical problem that the current grinding wheel heat dissipation method cannot adapt to the production of workpieces.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding wheel that is easy to assemble and disassemble, comprising a grinding wheel body, with fixed disc teeth installed at the center of both sides of the grinding wheel body, and concave and convex retaining teeth opened at the outer ends of the fixed disc teeth, a liquid storage tank opened on the outer side of the grinding wheel body, and a return liquid tank connected to the inner end of the liquid storage tank, and an outer liquid storage ring surrounding the outer periphery of the grinding wheel body, the return liquid tank being connected to the outer liquid storage ring, and a squeezing head provided inside the liquid storage tank, the squeezing head including an elastic clamp, the elastic clamp being made of elastic material, a squeezing sleeve installed at one end of the elastic clamp, and one-way valve heads respectively provided at the inner and outer positions of the squeezing sleeve inside and outside the liquid storage tank, the inlet and outlet ends of the one-way valve heads at the two positions being arranged in opposite directions.

[0005] Preferably, the outer liquid storage ring includes an upper shell and a lower shell, which together form a complete annular shell. The upper shell, the lower shell, and the outer periphery of the grinding wheel body are sealed. A positioning rod is connected to the bottom of the lower shell, and a stop rod is connected to the inner wall of the upper shell and the lower shell.

[0006] Preferably, the extrusion head includes a protruding head, which is a semi-circular spherical head body. The protruding head is connected to an elastic chuck. The outer periphery of the protruding head is arc-shaped and contacts a stop bar. A telescopic rod is connected between one side of the protruding head and the grinding wheel body. A spring is provided around the telescopic rod.

[0007] Preferably, the elastic clamp has an inner hollow shell on one side and a curved surface on the outer periphery of the elastic clamp, which is squeezed and deformed during the process of extending into and out of the liquid storage tank.

[0008] Preferably, the extrusion sleeve is made of a flexible and recoverable material, and a connecting rigid rod that penetrates the extrusion head is connected to the center of the extrusion sleeve.

[0009] Preferably, the one-way valve head includes a pipe head, on both sides of the inside of the pipe head are a flow-through plate and a flow-stop plate, a flow-through ball is provided between the inside of the flow-through plate and the flow-stop plate, and multiple limit rods are connected to the inside of the flow-through plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model establishes an internal cooling system by setting up a liquid storage tank, a liquid return tank, and an outer liquid storage ring on the grinding wheel body. This avoids direct contact between the coolant and the workpiece, effectively solving problems such as material corrosion, water stains, and product contamination caused by coolant spraying. It is particularly suitable for high-precision machining conditions where the use of coolant is limited, such as for aero-engine blades, precision molds, electronic components, and optical glass. It ensures the machining quality and performance of the workpiece and solves the problem that the cooling method of the grinding wheel cannot adapt to the production of the workpiece.

[0012] 2. This utility model also utilizes the coordinated operation of the extrusion head, one-way valve head, and elastic chuck. When the grinding wheel rotates, the extrusion head contacts the stop bar, driving the elastic chuck and extrusion sleeve to squeeze the coolant into the storage tank. After disengaging, the coolant returns to its original position and draws back into the tank, forming an automatic circulation of coolant. This circulating cooling method can promptly remove the heat generated by the friction between the grinding wheel and the workpiece, reduce the temperature of the processing area, reduce workpiece thermal deformation, and at the same time slow down the wear and shedding rate of the grinding wheel abrasive grains, extend the service life of the grinding wheel, reduce production costs, and further solve the problem that the heat dissipation method of the grinding wheel cannot adapt to workpiece production.

[0013] 3. This utility model also uses the fixed disc teeth on both sides of the grinding wheel body to cooperate with the externally adapted fixed teeth through the concave and convex teeth. It can be quickly installed and disassembled using a single bolt or elastic buckle similar to a folding umbrella. Compared with the traditional complicated fixing method, it greatly shortens the time for changing the grinding wheel, reduces the downtime of the equipment, and significantly improves the working efficiency of machining. It is especially suitable for machining scenarios that require frequent grinding wheel changes. Attached Figure Description

[0023] like Figures 1 to 6 As shown, this utility model relates to an easy-to-disassemble grinding wheel, including a grinding wheel body 1. Fixed disc teeth 2 are installed at the center of both sides of the grinding wheel body 1. The outer ends of the fixed disc teeth 2 are provided with concave and convex locking teeth. The concave and convex locking teeth cooperate with the external fixed locking teeth that are adapted to them to achieve convenient constraint and fixation. It can be easily disassembled and assembled by using a bolt or by using the elastic buckle of a folding umbrella, making disassembly and assembly more convenient.

[0024] A liquid storage tank 3 is provided on the outer side of the grinding wheel body 1. A return liquid tank 4 is connected to the inner end of the liquid storage tank 3. An outer liquid storage ring 5 surrounds the outer periphery of the grinding wheel body 1. The return liquid tank 4 is connected to the outer liquid storage ring 5. The outer liquid storage ring 5 includes an upper shell 501 and a lower shell 502. The upper shell 501 and the lower shell 502 form a complete ring shell. The upper shell 501, the lower shell 502 and the outer periphery of the grinding wheel body 1 are sealed. A positioning rod 503 is connected to the bottom of the lower shell 502. A stop rod 504 is connected to the inner wall of the upper shell 501 and the lower shell 502. The outer liquid storage ring 5 is filled with coolant.

[0025] Working principle: When the grinding wheel body 1 rotates at high speed to process the parts, it will come into contact with the coolant during the rotation. With the help of the coolant storage tank 3 and the coolant return tank 4, some of the coolant will enter the tank, thereby improving the cooling effect. Moreover, the cooling is an internal cooling method, which will not affect the processing of the parts.

[0026] While the above methods can achieve cooling, the coolant entering the internal tank during high-speed rotation of the grinding wheel undergoes centrifugal motion, thus the cooling effect cannot be guaranteed.

[0027] To achieve circulating cooling, a compression head 6 is installed inside the coolant storage tank 3. The compression head 6 includes a protruding head 601 and an elastic clamp 602. The protruding head 601 is a semi-circular spherical head body, connected to the elastic clamp 602. The outer periphery of the protruding head 601 is arc-shaped and contacts the stop rod 504. When it rotates, the arc of the protruding head 601 contacts the stop rod 504, thereby achieving inward contraction and displacement. A telescopic rod 9 is connected between one side of the protruding head 601 and the grinding wheel body 1. The telescopic rod 9 consists of a sleeve and a rod that are tenoned together, and it positions the protruding head 601 to prevent it from rotating. The telescopic rod 9 is surrounded by... The device includes a spring 10 and an elastic clamp 602 made of elastic material, preferably elastic metal. An inner shell 6021 is provided on one side of the elastic clamp 602, and a curved surface 6022 is provided on the outer periphery of the elastic clamp 602. The curved surface 6022 deforms during insertion and removal from the liquid storage tank 3. The maximum diameter of the outer arc end of the elastic clamp 602 is larger than that of the liquid storage tank 3, and the minimum diameter is smaller than that of the liquid storage tank 3, allowing it to compress and reset. A compression sleeve 7 is installed at one end of the elastic clamp 602. The compression sleeve 7 is made of a flexible and recoverable material, such as the material used in medical inflatable balls. A connecting rigid rod 11, penetrating the compression head 6, is connected to the center of the compression sleeve 7.

[0028] To facilitate circulation, the extrusion sleeve 7 is equipped with one-way valve heads 8 at both the inside and outside of the liquid storage tank 3. The inlet and outlet ends of the two one-way valve heads 8 are arranged in opposite directions. The one-way valve head 8 includes a pipe head 801. A flow-through plate 802 and a flow-stop plate 803 are installed on both sides inside the pipe head 801. A flow-stop ball 804 is provided between the flow-through plate 802 and the flow-stop plate 803. Multiple limiting rods 805 are connected to the inside of the flow-through plate 802. Through the suction and discharge forces of the extrusion sleeve 7, the flow-stop ball 804 can be moved. Thus, when the flow-stop ball 804 contacts and fits with the center hole of the flow-through plate 802, a seal is achieved. When it moves in the opposite direction, the flow-stop plate 803 will not seal due to its multiple holes, thus allowing flow.

[0029] Working principle: When the grinding wheel body 1 rotates, the arc-shaped protrusion 601 contacts the stop bar 504 and contracts. Simultaneously, the elastic chuck 602 contracts and is squeezed by the liquid storage tank 3, pressing the squeezing sleeve 7 to discharge the internal coolant into the liquid storage tank 3. After the arc-shaped protrusion 601 disengages from the stop bar 504, the squeezing sleeve 7 resets, and the one-way valve head 8 on the outside draws in liquid, causing the squeezing sleeve 7 to be refilled with coolant. This process can be repeated to input into the liquid storage tank 3 and return from the return tank 4, thus completing the cycle.

[0030] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
