Technical Field

[0001] This invention relates to the field of flange drilling technology, specifically to a drilling machine tool for processing flanges. Background Technology

[0002] Flanges are parts that connect pipes to each other. Flanges have holes that allow bolts to connect two flanges. The main function of a drilling machine that processes flanges is to drill holes in the flanges. By using a rotating drill bit to cut the flange surface, the diameter of the holes in the flanges is made uniform, thereby improving the sealing performance and service life of the flanges.

[0003] Patent CN220093820U discloses a drilling machine tool for processing flanges, including a base, a fixed plate, a support frame, and a pad, as well as a drilling assembly. The drilling assembly includes a rotating shaft, a servo motor, a worm gear, a worm wheel, a disc, a mounting frame, an electric push rod, a drilling motor, a vertical plate, a hydraulic rod, and a clamping block. This utility model belongs to the field of flange processing technology, specifically a drilling machine tool for processing flanges that can quickly clamp and fix flanges of different sizes and thicknesses, and can perform drilling operations on flanges of different diameters by adjusting the mounting frame at different installation positions. It also precisely rotates the disc to the appropriate angle, improving the processing effect and efficiency of flange processing.

[0004] However, the drilling machine tools currently used for processing flanges have the following problems: during the drilling process, the flange position may shift, which can easily cause inaccurate hole positions on the flange surface, leading to the problem of hole position shift on the flange surface. Therefore, we propose a drilling machine tool for processing flanges. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a drilling machine tool for processing flanges, which addresses the shortcomings of the prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a drilling machine tool for processing flanges, comprising a bottom shell, a top shell fixed to the top surface of the bottom shell, a square opening inside the top shell, a base plate fixed to the bottom inside the top shell, a square opening in the middle of the top surface of the base plate, the square opening of the base plate being aligned with the square opening of the top shell, a frame plate fixed to the top surface of the base plate, two sliding grooves and four slots on the top surface of the frame plate, an annular hole in the middle of the top surface of the frame plate, cross blocks slidably mounted on the inner walls of the sliding grooves of the frame plate, arc blocks fixed to the top surfaces of the cross blocks respectively, U-shaped blocks fixed to the bottom of the opposite sides of the arc blocks, L-shaped rods hinged to the inner walls of the U-shaped blocks, and the top of the bottom shell being... A long frame is fixed, with an electric telescopic rod extending through and fixed to the bottom of the frame. A long block is fixed to the top surface of the telescopic end of the electric telescopic rod. The long block is located inside the square opening of the base plate. A notch is opened on the top surface of the long block. The inner wall of the notch of the long block is hinged to the end of the L-shaped rod away from the U-shaped block. The arc block is used to clamp the two sides of the flange. The long block drives the L-shaped rod to move downward. Under the restriction of the cross block, the L-shaped rod rotates upward in the notch of the long block. The L-shaped rod rotates downward in the U-shaped block. The U-shaped block pushes the arc block to move towards the middle. The arc block drives the cross block to move towards the middle. The cross block slides towards the middle in the groove of the frame plate. During the process of moving towards the middle, the arc block clamps the two sides of the flange. The arc block pushes the flange to the middle of the frame plate.

[0007] According to the above technical solution, the frame plate is provided with four support columns, which are located on the side of the arc blocks that are far apart from each other. The L-shaped rods are located inside the two sliding grooves of the frame plate, and are located on the side of the cross blocks that are far apart from each other.

[0008] According to the above technical solution, the arc block is located on the left and right sides of the annular hole, the long block is located below the annular hole, and the electric telescopic rod is located on the left side inside the long frame.

[0009] According to the above technical solution, a frame is fixed at the top inside the bottom shell, a servo electric cylinder is fixedly installed on the inner wall of the frame, a plate is fixed on the bottom surface of the telescopic end of the servo electric cylinder, four motors are fixed on the bottom surface of the plate, and a drill bit is fixed on the bottom surface of the rotating shaft of each motor. The drill bit is located above the slot hole of the frame plate and is used to drill open the flange surface.

[0010] According to the above technical solution, an outer cover is fixed to the bottom edge of the plate, and holes are provided in the middle of the left and right sides of the outer cover. Two cylinders are fixed to the top surface of the bottom plate. The cylinders pass through and are fixed to the bottom surface of the frame plate. The outer wall of the cylinder is slidably connected to the inner wall of the hole block of the outer cover. The outer cover is used to limit the downward movement of the drill bit.

[0011] According to the above technical solution, a cooling device is provided on the top of the outer wall of the long block. The cooling device is used to cool the surface of the drill bit. A vibration damping device is provided on the front of the cooling device. The vibration damping device is used to reduce the vibration when the long block moves.

[0012] According to the above technical solution, the cooling device includes a U-shaped frame, which is fixed to the top of the outer wall of the long block. A cross-shaped nozzle is fixedly installed through the middle of the top surface of the U-shaped frame. A laser sensor is fixedly installed on the top surface of the cross-shaped nozzle. A flexible hose is installed at the bottom front of the cross-shaped nozzle. The cross-shaped nozzle is used to spray coolant onto the surface of the drill bit. The cross-shaped nozzle drives the laser sensor to move downward. When the cross-shaped nozzle moves above the annular hole, the laser emitted by the laser sensor senses the drill bit, and the cross-shaped nozzle sprays out coolant.

[0013] According to the above technical solution, a vertical plate is fixed to the front of the U-shaped frame, and several sets of rubber supports are fixed to the front of the vertical plate. The rubber supports are used to hold the hose. An L-shaped plate is fixed to the bottom of the back of the vertical plate. The vertical plate drives the rubber supports to move downward, and the vertical plate drives the L-shaped plate to move downward. The L-shaped plate lifts the hose, and the rubber supports drive the hose to move downward. The rubber supports limit the hose. The L-shaped plate is used to restrict the hose so that the hose will not wrap around the surface of the electric telescopic rod.

[0014] According to the above technical solution, the vibration damping device includes an L-shaped slip ring, which is fixed on both sides of the front of the L-shaped plate. Vertical frames are fixed on the left and right sides of the inner wall of the square opening of the base plate. The top surface of each vertical frame has a notch. A round rod is fixed at the bottom of each vertical frame. The inner wall of the L-shaped slip ring is slidably connected to the outer wall of the round rod. A spring is provided between the L-shaped slip ring and the vertical frame. The spring is sleeved on the round rod. The L-shaped slip ring slides downward on the round rod. The L-shaped slip ring drives the spring to move downward. Under the restriction of the vertical frame, the spring begins to contract. The elastic force of the spring compression is used to reduce the vibration when the long block moves.

[0015] According to the above technical solution, a convex plate is fixed on each of the L-shaped slip rings on opposite sides. The outer wall of the convex plate is slidably connected to the inner wall of the recess of the vertical frame. A pad is fixed on the top surface of the convex plate, and an arc-shaped rubber block is fixed on the bottom surface of the pad. The convex plate drives the pad to move downward, and the pad drives the arc-shaped rubber block to move downward. The arc-shaped rubber block contacts the vertical frame during the downward movement. The arc-shaped rubber block is used to prevent the L-shaped rod from hitting the top surface of the base plate.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0017] (1) The present invention uses a bottom shell, top shell, bottom plate, frame plate, annular hole, cross block, arc block, U-shaped block, L-shaped rod, long block and long frame in conjunction with an electric telescopic rod. The long block drives the L-shaped rod to move downward. Under the restriction of the cross block, the L-shaped rod rotates upward in the recess of the long block. The L-shaped rod rotates downward in the U-shaped block. The U-shaped block pushes the arc block to move towards the middle. The arc block drives the cross block to move towards the middle. The cross block slides towards the middle in the groove of the frame plate. During the process of moving towards the middle, the arc block clamps the two sides of the flange. The arc block pushes the flange to the middle of the frame plate. The arc block clamps and positions the flange to prevent the flange from shifting on the frame plate and causing the flange surface hole position to shift.

[0018] (2) By setting up a cooling device, the U-shaped frame, the cross nozzle and the laser sensor work together with the hose. The cross nozzle drives the laser sensor to move downward. When the cross nozzle moves above the annular hole, the laser emitted by the laser sensor senses the drill bit. The cross nozzle sprays out coolant to cool the drill bit and prevents the drill bit from overheating and being easily damaged by the drill bit of the drilling machine.

[0019] (3) The present invention uses a cooling device to make the vertical plate and the rubber support cooperate with the L-shaped plate. The vertical plate drives the rubber support to move downward, and the vertical plate drives the L-shaped plate to move downward. The L-shaped plate lifts the hose, and the rubber support drives the hose to move downward. The rubber support limits the hose and prevents the hose from getting tangled on the electric telescopic rod, which would cause the hose to be easily bent and damaged.

[0020] (4) By setting up a vibration damping device, the L-shaped slip ring, the vertical frame and the round rod cooperate with the spring. The L-shaped slip ring slides downward on the round rod. The L-shaped slip ring drives the spring to move downward. Under the restriction of the vertical frame, the spring begins to contract. The elastic force of the spring compression reduces the shaking when the long block moves downward. The spring limits the downward movement of the long block to prevent the arc block from excessively clamping the flange and causing damage to the flange surface.

[0021] (5) The present invention uses a vibration damping device to make the convex plate and the pad cooperate with the arc-shaped rubber block. The convex plate drives the pad to move downward, and the pad drives the arc-shaped rubber block to move downward. The arc-shaped rubber block contacts the vertical frame during the downward movement, preventing the L-shaped rod from hitting the bottom plate and causing the L-shaped rod to be easily deformed and damaged.

The support columns of the frame plate 4 are located on the side of the arc block 7 away from each other. The L-shaped rod 9 is located inside the two sliding grooves of the frame plate 4. The L-shaped rod 9 is located on the side of the cross block 6 away from each other. The arc block 7 is located on the left and right sides of the annular hole 5. The long block 10 is located below the annular hole 5. The electric telescopic rod 12 is located on the left side inside the long frame 11.

[0032] A frame 201 is fixed to the top of the bottom shell 1. A servo cylinder 202 is fixed to the inner wall of the frame 201. A plate 203 is fixed to the bottom surface of the telescopic end of the servo cylinder 202. Four motors 206 are fixed to the bottom surface of the plate 203. A drill bit 207 is fixed to the bottom surface of the shaft of each motor 206. The drill bit 207 is located above the slot of the frame plate 4. The drill bit 207 is used to drill open the flange surface. An outer cover 204 is fixed to the bottom edge of the plate 203. Holes are provided in the middle of the left and right sides of the outer cover 204. Two cylinders 205 are fixed to the top surface of the bottom plate 3. The cylinders 205 penetrate and are fixed to the bottom surface of the frame plate 4. The outer wall of the cylinder 205 is slidably connected to the inner wall of the hole of the outer cover 204. The outer cover 204 is used to limit the downward movement of the drill bit 207.

[0033] The bottom shell 1 supports the top shell 2, the top shell 2 supports the bottom plate 3, and the bottom plate 3 supports the frame plate 4. The operator places the flange onto the annular hole 5. The frame plate 4 supports the flange. The operator activates the electric telescopic rod 12 on the long frame 11. The telescopic end of the electric telescopic rod 12 begins to move downward, driving the long block 10 downward. The long block 10 moves downward in the square opening of the bottom plate 3, driving the L-shaped rod 9 downward. Under the constraint of the cross block 6, the L-shaped rod 9 rotates upward in the recess of the long block 10. The L-shaped rod 9 rotates downward in the U-shaped block 8, pushing the arc block 7 towards the center. The arc block 7 drives the cross block 6 towards the center. The cross block 6 slides towards the center in the groove of the frame plate 4. As the arc block 7 moves towards the center, it clamps both sides of the flange. The arc block 7 pushes the flange to the center of the frame plate 4. At the same time, the top shell 2 supports... The operator starts the servo cylinder 202 on the frame 201. The telescopic end of the servo cylinder 202 begins to move downward. The telescopic end of the servo cylinder 202 drives the plate 203 to move downward. The plate 203 drives the outer cover 204 to move downward. The outer cover 204 moves downward on the cylinder 205. At the same time, the plate 203 drives the motor 206 to move downward. The motor 206 drives the drill bit 207 to move downward. The operator starts the motor 206 on the plate 203. The shaft of the motor 206 begins to rotate. The shaft of the motor 206 drives the drill bit 207 to rotate. The drill bit 207 drills through the flange surface. During the flange processing process of the drilling machine, the arc block 7 clamps and positions the flange, preventing the flange from shifting on the frame plate 4. This avoids the problem of flange surface hole position shifting due to flange shifting on the frame plate 4 during flange processing.

[0034] A cooling device 13 is provided on the top of the outer wall of the long block 10. The cooling device 13 is used to cool the surface of the drill bit 207. A vibration damping device 14 is provided on the front of the cooling device 13. The vibration damping device 14 is used to reduce the vibration when the long block 10 moves.

[0035] Working principle: The flange is fitted onto the annular hole 5, and the support plate 4 supports the flange. The telescopic end of the electric telescopic rod 12 drives the long block 10 to move downward. The long block 10 moves downward in the square opening of the base plate 3. The long block 10 drives the L-shaped rod 9 to move downward. Under the constraint of the cross block 6, the L-shaped rod 9 rotates upward in the recess of the long block 10. The L-shaped rod 9 rotates downward in the U-shaped block 8. The U-shaped block 8 pushes the arc block 7 to move towards the center. The arc block 7 drives the cross block 6 to move towards the center. The cross block 6 slides in the groove of the support plate 4. The flange slides towards the center, and the arc block 7 clamps both sides of the flange as it moves towards the center. The arc block 7 pushes the flange to the center of the frame plate 4.

The shaft of the motor 206 drives the drill bit 207 to rotate. The drill bit 207 drills open the flange surface.

[0036] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the cooling device 13 includes a U-shaped frame 131, which is fixed to the top of the outer wall of the long block 10. A cross nozzle 132 is fixedly installed through the middle of the top surface of the U-shaped frame 131. A laser sensor 133 is fixedly installed on the top surface of the cross nozzle 132. A hose 134 is installed at the bottom of the front side of the cross nozzle 132. The cross nozzle 132 is used to spray coolant onto the surface of the drill bit 207.

[0037] As the long block 10 moves the L-shaped rod 9 downwards, the long block 10 moves the U-shaped frame 131 downwards, the U-shaped frame 131 moves the cross nozzle 132 downwards, the cross nozzle 132 moves the hose 134 downwards, the hose 134 is connected to the liquid storage tank, the cross nozzle 132 moves the laser sensor 133 downwards, and the cross nozzle 132 moves above the annular hole 5. When the drill bit 207 rotates and moves downwards, the laser emitted by the laser sensor 133 senses the drill bit 207, and the cross nozzle 132 sprays coolant to cool the drill bit 207, thereby avoiding the problem of the drill bit 207 being easily damaged due to overheating when the drilling machine is processing flanges.

[0038] A vertical plate 135 is fixed to the front of the U-shaped frame 131. Several sets of rubber supports 136 are fixed to the front of the vertical plate 135. The rubber supports 136 are used to hold the hose 134. An L-shaped plate 137 is fixed to the bottom of the back of the vertical plate 135. The L-shaped plate 137 is used to restrict the hose 134 so that the hose 134 will not wrap around the surface of the electric telescopic rod 12.

[0039] While the U-shaped frame 131 moves the cross nozzle 132 downward, the U-shaped frame 131 moves the vertical plate 135 downward, the vertical plate 135 moves the rubber support 136 downward, the vertical plate 135 moves the L-shaped plate 137 downward, the L-shaped plate 137 lifts the hose 134, the rubber support 136 moves the hose 134 downward, and the rubber support 136 limits the hose 134, thereby avoiding the problem that the hose 134 is easily bent and damaged when the drilling machine tool processes the flange and gets wrapped around the electric telescopic rod 12.

[0040] The vibration damping device 14 includes an L-shaped slip ring 141, which is fixed on both sides of the front of the L-shaped plate 137. Vertical frames 142 are fixed on the left and right sides of the square inner wall of the bottom plate 3. The top surface of the vertical frames 142 is provided with a notch. A round rod 143 is fixed at the bottom of the interior of the vertical frame 142. The inner wall of the L-shaped slip ring 141 is slidably connected to the outer wall of the round rod 143. A spring 144 is provided between the L-shaped slip ring 141 and the vertical frame 142. The spring 144 is sleeved on the round rod 143. The elastic force of the spring 144 is used to reduce the vibration when the long block 10 moves.

[0041] As the vertical plate 135 moves the L-shaped plate 137 downward, the L-shaped plate 137 moves the L-shaped slip ring 141 downward. The vertical frame 142 supports the round rod 143, and the L-shaped slip ring 141 slides downward on the round rod 143. The L-shaped slip ring 141 moves the spring 144 downward. Under the restriction of the vertical frame 142, the spring 144 begins to contract. The elastic force of the spring 144 reduces the shaking when the long block 10 moves downward. At the same time, when the spring 144 is compressed, it limits the downward movement of the long block 10, so that the arc block 7 does not excessively clamp the flange, thereby avoiding the problem of the arc block 7 excessively clamping the flange and causing damage to the flange surface when the drilling machine is processing the flange.

[0042] On the opposite sides of the L-shaped slip rings 141, a protruding plate 145 is fixed. The outer wall of the protruding plate 145 is slidably connected to the inner wall of the recess of the vertical frame 142. A pad 146 is fixed on the top surface of the protruding plate 145, and an arc-shaped rubber block 147 is fixed on the bottom surface of the pad 146. The arc-shaped rubber block 147 is used to prevent the L-shaped rod 9 from hitting the top surface of the base plate 3.

[0043] While the L-shaped slip ring 141 drives the spring 144 to move downward, the L-shaped slip ring 141 drives the convex plate 145 to move downward, the convex plate 145 drives the pad 146 to move downward, and the pad 146 drives the arc-shaped rubber block 147 to move downward. During the downward movement, the arc-shaped rubber block 147 contacts the vertical frame 142, so that the L-shaped rod 9 will not hit the base plate 3, thereby avoiding the problem that the L-shaped rod 9 is easily deformed and damaged when the drilling machine tool hits the base plate 3 during flange processing.

[0044] Working principle: The long block 10 drives the U-shaped frame 131 to move downward, the U-shaped frame 131 drives the cross nozzle 132 to move downward, the cross nozzle 132 drives the hose 134 to move downward, the hose 134 is connected to the liquid storage tank, the cross nozzle 132 drives the laser sensor 133 to move downward, the cross nozzle 132 moves above the annular hole 5, the laser emitted by the laser sensor 133 senses the drill bit 207, and the cross nozzle 132 sprays coolant onto the surface of the drill bit 207;

[0045] The U-shaped frame 131 drives the vertical plate 135 to move downward, the vertical plate 135 drives the rubber support 136 to move downward, the vertical plate 135 drives the L-shaped plate 137 to move downward, the L-shaped plate 137 lifts the hose 134, and the rubber support 136 drives the hose 134 to move downward.

[0046] L-shaped plate 137 drives L-shaped slip ring 141 to move downward. L-shaped slip ring 141 slides downward on round rod 143. L-shaped slip ring 141 drives spring 144 to move downward. Under the restriction of vertical frame 142, spring 144 begins to contract.

[0047] L-shaped slip ring 141 drives convex plate 145 to move downward, convex plate 145 drives pad 146 to move downward, pad 146 drives arc-shaped rubber block 147 to move downward, and arc-shaped rubber block 147 contacts vertical frame 142 during the downward movement.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
