Description

Technical Field

[0001] The utility model relates to a magnetic suction auxiliary device for underwater grinding, relates to transformer manufacturing, and particularly relates to a transformer air gap grinding process. Background Art

[0002] The existing magnetic meter base shell consists of two magnetic conductive parts separated by a non-magnetic copper plate. Inside is a rotatable magnet with north and south poles along the diameter. The principle is common knowledge.

[0003] At present, the existing technology uses a general hexagonal wrench to directly rotate the switch hexagonal hole of the disk. During the rotation process, the rotating tool and the operator are inevitably contaminated with grinding fluid, which is detrimental to pollution control and the health of the operator.

[0004] How to improve the sealing performance and avoid the grinding fluid from contaminating the operator and affecting his health has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The technical problem to be solved by this utility model is generally to provide a magnetic suction auxiliary device for underwater grinding. This utility model can operate the magnetic switch through the isolated glass, which is convenient to operate and does not come into contact with the grinding fluid during operation, thus protecting the operator more effectively. This solves the technical problem of the prior art that the grinding fluid may contaminate the wrench during operation, which is detrimental to the maintenance of the operating environment and has a certain impact on the health of the workers.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is:

[0007] In order to prevent the tool from entering the water, the magnetic base body is switched on and off. A magnetic suction auxiliary device for underwater grinding includes a magnetic base body arranged in a water tank;

[0008] The magnetic base body is provided with a horizontal knob switch hole;

[0009] A front baffle is sealed and installed on the front face of the water tank;

[0010] The front baffle is provided with a process perforation;

[0011] A water collector is sealed on the outer side wall of the front baffle;

[0012] A transverse through hole coaxial with the knob switch hole is provided on the water collector;

[0013] A manipulation handle is installed in the knob switch hole, the process through hole and the transverse through hole.

[0014] As a further improvement of the above technical solution:

[0015] For easy observation, the front baffle is a transparent glass plate.

[0016] A water separator is provided in the water tank; a process sink for installing tool setting instruments is provided in the water separator; a drainage hole is provided at the bottom of the process sink;

[0017] A circulating liquid tank is connected below the drainage through hole.

[0018] In order to facilitate the installation of the carrier, the upper surface of the magnetic base is used to attract the hollow carrier part.

[0019] In order to isolate the grinding fluid, it is avoided to provide a supporting flange at the end of the knob switch hole;

[0020] The operating handle includes a handle, a connecting shaft, a rotating shaft shoulder and a knob head which are connected in sequence;

[0021] The handle is a petal-shaped knob and is exposed on the water collector;

[0022] The connecting shaft passes through the transverse through hole and the process through hole;

[0023] The rotating shoulder is in the supporting flange;

[0024] The knob head is located in the knob switch hole;

[0025] A sealing ring is provided on the connecting shaft body.

[0026] In order to realize the circulation of grinding fluid, the front baffle has a liquid through hole;

[0027] The water collector includes a shell; a communicating inner cavity is provided in the shell; a water discharge nozzle is connected to the lower end of the shell;

[0028] The lower end of the discharge nozzle is connected to a circulating liquid tank.

[0029] A water inlet nozzle connected to the circulating liquid tank is provided in the water tank;

[0030] A petal opening is provided at the upper end of the water inlet;

[0031] The water inlet nozzle is connected to the circulating liquid tank pump.

[0032] To achieve smooth circulation, a pressure cap is placed on the petal opening;

[0033] The magnetic base separates the water inlet nozzle from the water collector.

[0034] The utility model has the advantages of reasonable design, low cost, durability, safety and reliability, simple operation, time and labor saving, money saving, compact structure and easy use.

[0035] One of the practical innovations of this device is the water collector. The operating handle of the disk switch is sealed by a shaft seal, which passes through the hole in the glass and rotates the hexagonal hole of the disk. The shaft seal itself cannot seal high pressure differentials for a long time, so the water collector adds another oil discharge channel, making the pressure in the water collector cavity close to atmospheric pressure. Therefore, the pressure distribution is: the pressure in the water tank (the pressure generated by the depth of the liquid surface on the disk side) > the pressure inside the water collector cavity (connected to the atmosphere through the discharge channel) ≈ the pressure of the environment in which the operating handle is located (atmospheric pressure). This design makes the working pressure difference of the shaft seal of the operating handle close to zero, so the grinding fluid will not seep out of the shaft seal, but will be relieved through the discharge channel of the water collector. This design eliminates the need to contact the grinding fluid during the operation of the disk switch, avoiding contamination and spillage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] like Figure 1-4 As shown, the magnetic suction auxiliary device for underwater grinding of this embodiment includes a magnetic base body 303 disposed in the water tank 101, which is attracted by an externally purchased magnetic suction base. Since it is purchased externally, this part of the accompanying drawing is a schematic diagram;

[0042] The magnetic base body 303 has a horizontal knob switch hole 306, which is convenient for inserting a plug and driving the rotation to achieve engagement or release.

[0043] A front baffle 302 is sealed and installed on the front end surface of the water tank 101. The front baffle 302 is separate from the water tank body and is a transparent glass plate.

[0044] Adopt transparent plate to achieve sealing and fit, which is convenient for observation;

[0045] The front baffle 302 is provided with a process perforation; a water collector 311 is sealed and provided on the outer side wall of the front baffle 302; and the water collector 311 can be sealed and bonded.

[0046] A transverse through hole 312 is provided on the water collector 311 and is coaxial with the knob switch hole 306;

[0047] An operating handle is installed in the knob switch hole 306, the process through hole, and the transverse through hole 312. Compared with immersing the hexagonal wrench in grinding fluid, it does not cause contamination of the wrench and avoids operator contact.

[0048] To reduce liquid splashing and resonance and prevent liquid contamination of the tool setting instrument, a water block 201 is provided in the water tank 101. A process sink 207 for mounting tool setting instrument components is provided in the water block 201. A drainage hole 301 is provided at the bottom of the process sink 207. Even if grinding fluid occasionally enters the process sink 207, it will naturally drain through the drainage hole 301.

[0049] A circulating liquid tank is connected below the drainage through hole 301 and is provided with a pump for settling and filtering the grinding fluid.

[0050] The upper surface of the magnetic base 303 is used to attract the hollow carrier portion 304 to facilitate carrying the workpiece.

[0051] A supporting flange 305 is provided at the end of the knob switch hole 306, which realizes sealing and isolation of the knob switch hole, preventing debris and grinding fluid from entering the hole and causing contamination; a connecting sleeve of the rotating shaft of the magnetic base body 303 is provided in the knob switch hole 306; the connecting sleeve is an inner hexagonal sleeve or a spline hole, etc.

[0052] As a specific explanation, the operating handle includes a handle 310, a connecting shaft 309, a rotating shaft shoulder 308 and a knob head 307 connected in sequence;

[0053] The handle 310 is a petal-shaped knob and is exposed outside the water collector 311, thereby facilitating the rotation operation.

[0054] The connecting shaft 309 passes through the transverse through hole 312 and the process through hole to achieve the transmission of rotational force;

[0055] The rotating shoulder 308 is in the supporting flange 305; a sealed connection is achieved, thereby isolating.

[0056] The knob head 307 is located in the knob switch hole 306; through transmission cooperation, the driven rotation is achieved.

[0057] A sealing ring is provided on the connecting shaft 309, which does not have a pressure difference, thereby ensuring that the grinding fluid does not leak out and ensuring the durability of the sealing ring.

[0058] The front baffle 302 has a liquid passage 314 to achieve the circulation of the grinding fluid;

[0059] The water collector 311 includes a shell; a communicating inner cavity 313 is provided in the shell to realize the downward flow of the grinding fluid at the connection shaft 309; a water discharge nozzle 315 in the communicating inner cavity is connected to the lower end of the shell;

[0060] In the intercommunication inner cavity 313, free communication between the water tank and the circulating liquid tank is achieved;

[0061] The lower end of the discharge nozzle 315 is connected to a circulating liquid tank to achieve liquid sedimentation and filtration.

[0062] A water inlet 316 connected to the circulating liquid tank is provided in the water tank 101 to return the filtered grinding fluid;

[0063] A petal opening 317 is provided at the upper end of the water inlet nozzle 316 ; a pressure cap is placed on the petal opening 317 ; and the water inlet nozzle 316 is connected to a circulating liquid tank pump, so that the grinding fluid can return to the water tank through the gap of the petal opening 317 .

[0064] The magnetic base 303 separates the water inlet 316 from the water collector 311, thereby extending the distance of the grinding fluid and achieving better circulation of the grinding fluid.

[0065] The water collector has an additional oil drain channel, bringing the pressure inside the collector chamber close to atmospheric pressure. This design allows the operating handle, which acts as a disk switch, to be operated without contact with the grinding fluid, preventing contamination from spilling.

[0066] like Figure 1-4 As shown in the figure, in practice, the seal between the control handle and the manifold is achieved through two oil seals. The disk side serves as a grinding fluid reservoir, so the grinding fluid enters the cavity between the manifold and the glass through the gap between the control handle and the glass hole and another drain hole in the glass. The manifold's drain nozzle directs any leaked grinding fluid into the open circulating fluid tank. Therefore, the pressure in the cavity between the manifold and the glass is very close to atmospheric pressure. However, the control handle with a five-pointed handle is exposed to the atmosphere, which greatly reduces the operating pressure of the oil seal sealing the gap between the control handle and the manifold, eliminating the possibility of grinding fluid leakage through the oil seal.

[0067] The present invention is fully described for the purpose of clearer disclosure, and the prior art will not be listed one by one.
