Description

However, since both ends of the petroleum valve body need to be drilled, and the workbench in the traditional machine tool usually does not have a flipping function, the machine tool can only drill one end of the valve body after the petroleum valve body is fixed to the workbench. After completing the drilling of one end, the worker needs to manually adjust the position of the valve body and re-fix it so as to drill the other end of the valve body. This operation not only increases the labor intensity of the workers, but also may lead to a decrease in processing accuracy, because each time the valve body is re-fixed, new errors may be introduced, and this method also reduces the overall processing efficiency; Although there are machine tools in the prior art that can drill holes at both ends at the same time without manually adjusting the position of the valve body, such machine tools need to be equipped with more spindles and complex control systems, and the manufacturing and maintenance costs are higher; Therefore, it is necessary to design a flange hole processing device specifically suitable for petroleum valve bodies in view of the defects of the two machine tools, which can not only realize automatic adjustment of the valve body position, but also reduce manufacturing and maintenance costs.

[0026] Embodiment 1: A device for machining flange holes of a petroleum valve body, such as Figure 1-Figure 4 As shown, the machine table 1 includes an electric turntable 101, a reversing shaft 102, a processing seat 103, a motorized frame 104, an electric slide seat 105, a drill 106, a first rack 107 and a reversing gear 108.

The technician can drive the drills 106 on the lathe turret to rotate by installing a driving source. This is a conventional technical means and will not be described here. A first rack 107 is fixedly connected to the front side of the electric slide 105. Figure 3 It can be seen that the reversing shaft 102 is rotatably connected to the reversing gear 108 through a one-way bearing, the first rack 107 cooperates with the reversing gear 108, and only when the electric slide 105 is reset in a direction away from the electric turntable 101, the first rack 107 can drive the reversing shaft 102 to rotate through the reversing gear 108.

[0027] like Figure 3 As shown, it also includes a fixing clamp 2 and an electric push rod 201 for fixing the valve body. Each processing seat 103 is symmetrically slidably connected with two fixing clamps 2. The shapes of the opposite ends of the two fixing clamps 2 match the outer surface of the valve body. Each processing seat 103 is fixedly connected with an electric push rod 201. Both ends of the electric push rod 201 are provided with telescopic shafts, and the telescopic shafts are fixedly connected to the fixing clamp 2 on the same side.

[0028] When drilling is required for the valve body, the valve body is intermittently placed on the processing seat 103 on the left, and then the electric push rod 201 is controlled to drive the fixing clamp 2 to clamp the valve body on the processing seat 103, and the electric turntable 101 will intermittently rotate counterclockwise by 90 degrees, so that the processing seat 103 on the left is rotated to face the electric slide 105, and then the electric slide 105 is controlled to move in the direction close to the electric turntable 101, and the drill bit 106 is controlled to rotate, so that the flange hole is drilled on the valve body by the drill bit 106, and then the electric slide 105 is controlled to reset in the direction away from the electric turntable 101, and the electric When the movable slide 105 is reset, the drill hole will first withdraw from the flange hole, and then the first rack 107 and the reversing gear 108 will mesh and drive the reversing shaft 102 to rotate 180 degrees. The reversing shaft 102 will drive the electric slide 105 to rotate synchronously to adjust the direction of the valve body, and then the electric slide 105 will be controlled to move toward the electric turntable 101 again, so as to drill the other end of the valve body. The electric slide 105 reciprocates twice to complete the drilling of the two ends of the valve body, and then the electric turntable 101 is controlled to rotate counterclockwise 90 degrees to rotate the next valve body to be drilled to the drilling processing position.

[0029] Embodiment 2: Based on embodiment 1, Figure 4 and Figure 5 As shown, it also includes a feeding mechanism for placing the valve body on the processing seat 103. The feeding mechanism is installed on the machine table 1. The feeding mechanism includes a feeding rack 3, a feeding frame 301, a support block 302 and a clamping claw 303. A feeding rack 3 is arranged on the left side of the machine table 1. Two feeding frames 301 are symmetrically fixedly connected to the feeding rack 3. The valve bodies are stacked and placed between the two feeding frames 301. A support block 302 is fixedly connected to each feeding frame 301. There are four support blocks 302 in total. Each support block 302 is rotatably connected to a clamping claw 303. The clamping claw 303 is used to control the valve body to fall onto the processing seat 103 below.

[0030] like Figure 3 , Figure 5 and Figure 6 As shown, it also includes a control mechanism for driving the clamping claw 303, the control mechanism is connected to the fixing clamp 2, the control mechanism includes a torsion spring 304, a material release buckle 305, a plug rod 306, an unlocking plate 307, a small spring 308, an external rod 309, a top block 310 and a top rod 311, a torsion spring 304 is sleeved on the rotating shaft of the clamping claw 303, one end of the torsion spring 304 is fixedly connected to the clamping claw 303, and the other end of the torsion spring 304 is fixedly connected to the supporting block 302, and a material release buckle 305 is fixedly connected to the rotating shaft of the clamping claw 303. When the two clamping claws 303 are in Figure 4 and Figure 5 When the valve body is in the closed state to prevent the valve body from falling, the discharge buckle 305 is tilted, and the support block 302 is slidably connected with the insertion rod 306 in the vertical direction. Figure 6It can be seen that the rotating shaft of the claw 303 is provided with a socket 312 for inserting the plug rod 306, the plug rod 306 is fixed with an unlocking plate 307, and the plug rod 306 is sleeved with a small spring 308, when the plug rod 306 moves upward, the small spring 308 is compressed, Figure 3 It can be seen that an external rod 309 is fixedly connected to the fixing clamp 2, and a top block 310 is fixedly connected to the external rod 309. The upper end of the top block 310 is provided with an arc surface. The top block 310 is used to squeeze the discharge buckle 305 to drive the claw 303 to rotate. A top rod 311 is fixedly connected to the top block 310, and an inclined surface is provided on the top rod 311. The top rod 311 is used to squeeze the unlocking plate 307 upwards to drive the insertion rod 306 to withdraw from the insertion hole 312.

[0031] like Figure 2 and Figure 3 As shown, it also includes a guide plate 404 and a material picking seat 405. Four guide plates 404 are fixedly connected to the circumference of the electric turntable 101. A material picking seat 405 is slidably connected between two adjacent guide plates 404. The material picking seat 405 slides in the vertical direction. There are four material picking seats 405 in total, and the material picking seat 405 is slidably connected to the electric turntable 101. The reversing shaft 102 is rotatably connected to the material picking seat 405. The material picking seat 405 is used to drive the processing seat 103 to move upward to facilitate receiving the valve body.

[0032] like Figure 2 and Figure 5 As shown, it also includes a transfer mechanism for driving the material picking seat 405 to rise and fall, the transfer mechanism is connected to the electric slide 105, the transfer mechanism includes a slide bar 4, a hinged rod 401, a slider 402, a side bracket 403, a protrusion 406 and a recessed block 407, the electric slide 105 is fixedly connected to the slide bar 4, the lower end of the slide bar 4 is slidably connected to the motor frame 104, the end of the slide bar 4 away from the electric slide 105 is rotatably connected to the hinged rod 401, the end of the hinged rod 401 away from the slide bar 4 is rotatably connected to the slide bar 4, the side bracket 403 is fixedly connected to the machine 1, the slider 402 is slidably connected to the side bracket 403 in the vertical direction, the slider 402 is fixedly connected to one side of the bracket away from the side, each of the material picking seats 405 is fixedly connected to a protrusion 406, and each time the electric turntable 101 stops, the recessed block 407 will be clamped together with the protrusion 406 on one of the material picking seats 405.

[0033] The initial position of the insertion rod 306 is located in the insertion hole 312. At this time, the claw 303 cannot rotate. The valve body to be drilled is stacked and placed in the discharge frame 301 in advance. The claw 303 that cannot rotate will prevent the valve body from falling downward. When the electric slide seat 105 moves in the direction close to the electric turntable 101, the slider 402 slides upward along the side bracket 403. The slider 402 drives the left material picking seat 405 to move upward through the protrusion 406 and the concave block 407, thereby driving the processing seat 103 upward and close to the discharge frame 301. In this process, the electric push rod 201 is controlled to drive the two fixing clamps 2 to move relative to each other. The push rod 311 will first contact the unlocking plate 307 and squeeze the unlocking plate 307 upward. The unlocking plate 307 will drive the insertion rod 306 to withdraw from the insertion hole 312 and compress the small spring 308, so that the insertion rod 306 no longer restricts the rotation of the claw 303. Figure 5 The cam 306 is pressed against the top of the workpiece 307 and the cam 308 is pressed against the top of the workpiece 307, thereby releasing the cam 306 and releasing the cam 308. Figure 1 and Figure 4 It can be seen that the blocking position of the claws 303 is located on both sides of the valve body, and a protruding pipe is provided on the upper side of the valve body, which will press against the lower end of the upper valve body. Therefore, during the downward movement of the processing seat 103, the valve body in the discharge frame 301 can only move downward synchronously with the processing seat 103, and during this process, the claws 303 have been able to complete the reset, so the upper valve body will not be stuck between the two claws 303, resulting in the claws 303 being unable to reset normally; since the electric slide 105 needs to move back and forth twice, the electric push rod 201 of the device will not drive the fixing clamp 2 to move relative to each other when the electric slide 105 moves for the first time, that is, the electric slide 105 will not place the valve body on the processing seat 103 when it reciprocates for the first time, so as to prevent the valve body on the processing seat 103 from colliding with the valve body in the discharge frame 301 when the processing seat 103 moves upward for the second time.

[0034] Embodiment 3: Based on embodiment 2, Figure 1 , Figure 4 and Figure 7As shown, it also includes a material taking mechanism for taking the valve body out of the processing seat 103, the material taking mechanism is installed on the motorized frame 104, the material taking mechanism includes a material taking frame 5, a material taking clamp 501, a material taking spring 502, a driven block 503, a material unloading frame 504, an active block 505 and a conveyor 506, and the machine table 1 is fixedly connected with two motorized frames 104 arranged symmetrically in front and back, the electric slide seat 105 is installed on the motorized frame 104 on the rear side, and the motorized frame 104 on the front side is also slidably connected with a slide bar 4, the slide bar 4 and the slider 402 are also connected by a hinged rod 401, and the two slide bars 4 of the motorized frame 104 on the front side are fixedly connected with the material taking frame 5, combined with Figure 1 and Figure 7 It can be seen that there are two material picking clamps 501 slidably connected to the material picking frame 5 in the vertical direction. The two material picking clamps 501 are arranged opposite to each other, and the opposite ends of the two material picking clamps 501 are arc-shaped. The material picking clamps 501 are used to clamp the valve body to remove the valve body from the processing seat 103. The material picking clamps 501 are both sleeved with material picking springs 502. When the two material picking clamps 501 move in opposite directions, the material picking springs 502 will be compressed. Two driven blocks 503 arranged in opposite directions are fixedly connected to the material picking clamps 501. Figure 4 It can be seen that a material unloading rack 504 is fixedly connected to the front motorized rack 104, and two active blocks 505 are fixedly connected to the material unloading rack 504. The active blocks 505 are used to squeeze the driven blocks 503 to drive the material picking clamps 501 to move in opposite directions. A conveyor 506 for conveying the valve body to the next process is installed on the machine platform 1, and the conveyor 506 is located below the material unloading rack 504.

[0035] When the slider 402 moves upward, it will drive the material picking frame 5 to move toward the direction of the electric turntable 101 through the hinge rod 401 and the slide rod 4, and the material picking frame 5 will drive the material picking clamp 501 to move synchronously. When the driven block 503 and the active block 505 are out of contact, the material picking spring 502 will push the two material picking clamps 501 to move relative to each other. When the motorized frame 104 moves forward, the two material picking clamps 501 will contact the protruding edge of the front side of the valve body, thereby Figure 7 It can be seen that one side of the material picking clamp 501 is provided with an arc surface, and the valve body will squeeze the arc surface to make the material picking clamps 501 move in opposite directions. When the material picking clamps 501 move to the inner side of the protruding edge of the valve body, they will reset under the action of the material picking spring 502, and the two material picking clamps 501 will be clamped on the front side of the valve body, and then the corresponding fixing clamp 2 of the valve body is controlled to release the clamping of the valve body. During the movement of the material picking rack 5 away from the electric turntable 101, the material picking clamp 501 will drive the valve body to move synchronously, and then the active block 505 contacts and squeezes the driven block 503, so that the driven block 503 drives the two material picking clamps 501 to move in opposite directions, so that the material picking clamps 501 release the clamping of the valve body, and the valve body falls downward onto the conveyor 506 for transportation to the next process.

[0038] like Figure 8 As shown, a rubber block 8 is also included. The end of the brush roller 605 away from the translation seat 604 is fixedly connected with the rubber block 8. The rubber block 8 is cylindrical, and the diameter of the rubber block 8 matches the inner diameter of the flange hole.

[0039] When the slider 402 moves upward, it will drive the vertical slide 6 to move upward. Since the power guide rail 602 is inclined, when the vertical slide 6 moves upward, the power guide rail 602 will drive the translation seat 604 to slide in the direction of the electric turntable 101 through the transmission shaft 7, so that the brush roller 605 can enter the flange hole, and the transmission rack 603 will drive the transmission shaft 7 to rotate through the No. 1 gear 701, and the transmission shaft 7 will drive the brush roller 605 to rotate through the No. 2 gear 702, the No. 3 gear 703 and the No. 4 gear 704, so as to grind the inside of the flange hole and And because the diameter of the brush roller 605 is larger than the inner diameter of the flange hole, the brush roller 605 can contact the edges and corners of the outer end of the flange hole to grind the burrs on the edges and corners smooth; when the slider 402 is reset downward, the vertical slide seat 6 will also slide downward, and the translation seat 604 will reset in the direction away from the electric turntable 101. When the brush roller 605 withdraws from the flange hole, the second gear will engage with the reversing gear 108, and the processing seat 103 will be driven to rotate one hundred and eighty degrees through the reversing gear 108, thereby adjusting the direction of the valve body to facilitate the grinding of the flange hole at the other end.

[0040] Since the rubber block 8 is elastic and the outer diameter of the rubber block 8 matches the inner diameter of the flange hole, the rubber block 8 can fit in contact with the inner wall of the flange hole. Before the brush roller 605 enters the flange hole, the rubber block 8 will first enter the flange hole to push out the debris remaining in the flange hole to prevent the debris from affecting the grinding. In the process of the brush roller 605 withdrawing from the flange hole, the rubber block 8 will scrape out the crushed or debris ground out of the flange hole.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
