Description

Technical Field

This type of flange not only needs to withstand extreme temperature conditions, but also ensure a high degree of sealing in a vacuum environment to maintain the stable operation of the system. Therefore, drilling of high temperature resistant vacuum flange is a precise and demanding task.

[0003] Flange processing equipment is required when drilling holes in high-temperature resistant vacuum flanges.

[0022] The present invention provides a high temperature resistant vacuum flange processing equipment and processing technology. Compared with the prior art, it has the following beneficial effects:

[0023] 1. The present invention provides a high-temperature resistant vacuum flange processing equipment. The operator can control the uniform speed motor to be powered on and run through the controller to drive the turntable to rotate according to the processing requirements. The rotating turntable can drive the idle speed motor to rotate to a specified position, so that the drill bit of the specified specification rotates to the top of the high-temperature resistant vacuum flange to be processed. The operator then controls the electric push rod to be powered on to a specified stroke through the controller, thereby driving the idle speed motor to move to the specified position, which plays a role in adjusting the drilling position of the high-temperature resistant vacuum flange to be processed, and then drives the drill bit to rotate by powering on the idle speed motor, and drives the idle speed motor to move the vertical position by powering on the electric rod, so that the rotating drill bit contacts the top of the high-temperature resistant vacuum flange to be processed for drilling processing, which plays a role in adjusting the processing aperture of the high-temperature resistant vacuum flange to be processed. The electric push rod and the uniform speed motor are used in combination to realize the function of adjusting the processing aperture and position of the high-temperature resistant vacuum flange to be processed, thereby avoiding the device being easily restricted by the specifications of the high-temperature resistant vacuum flange to be processed, expanding the scope of application of the device, providing compatibility of the device, and facilitating the popularization and use of the device.

[0024] 2. The present invention provides a high-temperature resistant vacuum flange processing equipment, which forms a passage between the three-way pipe and the first filter box by energizing the first solenoid valve tube, and then generates suction to absorb the air inside the first filter box by energizing the air pump, so that the interior of the first filter box is in a negative pressure state. The first filter box in the negative pressure state can absorb the air inside the box through the three-way pipe, so that the interior of the device is in a vacuum state, which is convenient for suppressing the oxidation reaction when processing the high-temperature resistant vacuum flange, avoiding the generation of reddish-brown iron oxide smoke due to oxidation of steel when drilling the high-temperature resistant vacuum flange, and can maintain the purity of the material at the drilling site, avoiding the oxide layer from having adverse effects on subsequent processing or use.

[0025] 3. A high-temperature resistant vacuum flange processing equipment provided by the present invention drives the pressure sensor to move horizontally by energizing the electric cylinder. The pressure sensor that moves horizontally can drive the clamp to clamp and fix the high-temperature resistant vacuum flange to be processed. The clamping force on the high-temperature resistant vacuum flange can be monitored in real time by energizing the pressure sensor, and the monitoring electromagnetic signal is transmitted to the controller for calculation through conduction. When the controller calculates that the monitoring value of the pressure sensor reaches a preset value, the electric cylinder is energized and stopped by the wire, thereby realizing the function of safety protection for the high-temperature resistant vacuum flange to be processed, avoiding the problem that excessive clamping force may easily cause slight deformation of the local part of the high-temperature resistant vacuum flange, resulting in reduced sealing when the high-temperature resistant vacuum flange is used subsequently, and excessively small clamping force may easily cause the high-temperature resistant vacuum flange to be processed to move in position under force, thereby improving the intelligent effect of the device.

[0036] The adjustment mechanism 2 includes an electric rod 201, a uniform speed motor 202 is fixedly installed at the output end of the electric rod 201, a turntable 203 is fixedly installed at the output end of the uniform speed motor 202, a plurality of electric push rods 204 are equidistantly installed inside the turntable 203, an idle speed motor 205 is fixedly installed at the output end of the electric push rod 204, and a drill 206 for processing a high temperature resistant vacuum flange is fixedly installed at the output end of the idle speed motor 205;

[0037] The negative pressure mechanism 3 includes a three-way pipe 301, a first electromagnetic valve pipe 302 is fixedly installed at one end of the three-way pipe 301, and a second electromagnetic valve pipe 303 is fixedly installed at the other end of the three-way pipe 301. A hinge is fixedly installed on one side of the front of the box body 1, and a box door 101 is movably installed on one side of the hinge.

[0038] A first filter box 304 is fixedly installed at one end of the first solenoid valve tube 302, an air pump 305 is fixedly installed at the bottom of the first filter box 304 through a pipe, and a second filter box 306 is fixedly installed at one end of the second solenoid valve tube 303, and two sets of nanoporous plates 307 are fixedly installed inside the first filter box 304 and the second filter box 306;

[0039] A protection box 5 is fixedly installed on the outside of the adjustment mechanism 2, and one side of the protection box 5 is fixedly connected to one side of the box body 1. A controller 6 is fixedly installed on the top of the front of the box body 1, and a display screen is fixedly installed on one side of the front of the controller 6.

[0040] A fixed block is fixedly installed on one side of the top of the box body 1 close to the negative pressure mechanism 3, and a pressure gauge 7 for real-time monitoring of the internal pressure of the box body 1 is fixedly installed on the top of the fixed block, two sets of threaded foot sleeves are fixedly installed on both sides of the bottom of the box body 1, and threaded foot rods 8 are threadedly installed inside the threaded foot sleeves, and a synchronous motor 9 is fixedly installed at the center of the bottom of the box body 1, and the output end of the synchronous motor 9 is fixedly connected to the bottom of the fixed disk 401.

[0041] By opening the box door 101, it is convenient for maintenance personnel to perform maintenance operations on the electrical equipment inside the device, avoiding the problem of needing to disassemble the device before performing maintenance operations on the electrical equipment inside the device, providing convenience for subsequent maintenance personnel, increasing the convenience effect of using the device, and facilitating the placement and removal of the high-temperature resistant vacuum flange to be processed;

[0042] The high temperature resistant vacuum flange to be processed can be clamped and fixed by the driving mechanism 4, and then the driving mechanism 4 can be driven to rotate by the synchronous motor 9. The rotating driving mechanism 4 can drive the high temperature resistant vacuum flange to be processed to rotate, thereby achieving the purpose of adjusting the processing position of the high temperature resistant vacuum flange and increasing the automation effect of the device;

[0043] The first solenoid valve tube 302 is powered on to form a passage between the three-way pipe 301 and the first filter box 304, and then the air pump 305 is powered on to generate suction to absorb the air inside the first filter box 304, so that the first filter box 304 is in a negative pressure state. The first filter box 304 in a negative pressure state can absorb the air inside the box body 1 through the three-way pipe 301, so that the inside of the device is in a vacuum state, which is convenient for inhibiting the oxidation reaction when processing the high-temperature vacuum flange. In a vacuum environment, due to the lack of oxygen, the high temperature generated by the friction between the high-temperature vacuum flange and the drill bit 206 is difficult to induce an oxidation reaction. Therefore, compared with drilling in the air, in a vacuum environment, almost no smoke formed by material oxidation will be generated;

[0044] When the vacuum state inside the device needs to be released, the second solenoid valve tube 303 is powered on to open, and the outside air is filtered through the second filter box 306 and then enters the device, thereby releasing the vacuum state inside the device;

[0045] According to the processing requirements, the operator can control the uniform speed motor 202 through the controller 6 to drive the turntable 203 to rotate, and the rotating turntable 203 can drive the idle speed motor 205 to rotate to the specified position, so that the drill bit 206 of the specified specification rotates to the top of the high temperature resistant vacuum flange to be processed;

[0046] The operator then controls the electric push rod 204 to be energized to the specified stroke through the controller 6, thereby driving the idle motor 205 to move to the specified position, which plays a role in adjusting the drilling position of the high-temperature resistant vacuum flange to be processed, and then drives the drill bit 206 to rotate by energizing the idle motor 205, and drives the electric rod 201 to drive the idle motor 205 to move the vertical position, so that the rotating drill bit 206 contacts the top of the high-temperature resistant vacuum flange to be processed to perform the drilling operation, which plays a role in adjusting the processing aperture of the high-temperature resistant vacuum flange to be processed. The electric push rod 204 and the uniform speed motor 202 are used in conjunction to realize the function of adjusting the processing aperture and position of the high-temperature resistant vacuum flange to be processed;

[0047] The protective box 5 can provide an installation position for the adjustment mechanism 2, provide a moving space for the adjustment mechanism 2, and facilitate the safety protection of the adjustment mechanism 2, thereby ensuring the safety effect of the use of the adjustment mechanism 2;

[0048] The controller 6 is electrically connected to the internal electrical equipment of the device through a wire, so that the operator can intelligently control the internal electrical equipment of the device through the controller 6 to power on and run. The operator can understand the running status of the internal electrical equipment of the device through the display screen, so as to control the power on and running status of the internal electrical equipment of the device according to the use requirements, thereby increasing the intelligent effect of the device.

[0049] The fixing block can provide an installation position for the pressure gauge 7, and the pressure gauge 7 can facilitate the operator to intuitively understand the negative pressure state inside the device. The operator can rotate the threaded foot rod 8 to extend the threaded foot rod 8 out of the threaded foot sleeve until it contacts the ground, thereby realizing the function of adjusting the use height of the device, which is convenient for adjusting the use height of the device according to usage requirements.

[0050] The second embodiment is mainly different from the first embodiment in that: the driving mechanism 4 includes a fixed plate 401, two sets of fixed frames 402 are fixedly installed on the top of the fixed plate 401, an electric cylinder 403 is fixedly installed on one side of the fixed frame 402, a pressure sensor 404 for real-time monitoring of the clamping force of the high-temperature resistant vacuum flange is fixedly installed on the output end of the electric cylinder 403, and a clamp 405 for clamping and fixing the high-temperature resistant vacuum flange is fixedly installed on one side of the pressure sensor 404.

[0051] The electric cylinder 403 is powered on to drive the pressure sensor 404 to move horizontally, so that the clamp 405 clamps and fixes the high-temperature resistant vacuum flange. The pressure sensor 404 can monitor the clamping force on the flange in real time and transmit the monitoring electromagnetic signal to the controller 6 for calculation. When the controller 6 determines that the monitoring value of the pressure sensor 404 reaches the preset value, the electric cylinder 403 is controlled to stop running, thereby realizing the safety protection function of the high-temperature resistant vacuum flange.

[0052] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0055] S2: The electric cylinder 403 is powered on to drive the pressure sensor 404 to move horizontally, so that the fixture 405 clamps and fixes the high-temperature resistant vacuum flange. Then, the pressure sensor 404 cooperates with the controller 6 to intelligently control the electric cylinder 403 to stop running, thereby realizing the safety protection function of the high-temperature resistant vacuum flange.

[0056] S3: The first solenoid valve tube 302 is powered on to form a passage between the three-way tube 301 and the first filter box 304, and then the air pump 305 is powered on to generate suction to absorb the air inside the first filter box 304, so that the first filter box 304 is in a negative pressure state, and then the air inside the box body 1 is absorbed through the three-way tube 301, so that the inside of the device is in a vacuum state. This vacuum environment is convenient for inhibiting oxidation reactions when processing high-temperature resistant vacuum flanges;

[0057] S4: The controller 6 controls the uniform speed motor 202 to be powered on and drive the turntable 203 to rotate, so that the idle speed motor 205 and the drill bit 206 of the specified specification rotate to the top of the high temperature resistant vacuum flange to be processed, and then controls the electric push rod 204 to be powered on to the specified stroke to drive the idle speed motor 205 to move and adjust the drilling position. The idle speed motor 205 is powered on to drive the drill bit 206 to rotate, and the electric rod 201 is powered on to drive the idle speed motor 205 to move vertically to adjust the processing aperture. The electric push rod 204 cooperates with the uniform speed motor 202 to achieve the function of adjusting the processing aperture and position of the high temperature resistant vacuum flange to be processed.
