Description

Technical Field

[0001] The invention relates to the technical field of drilling, in particular to an automatic flange drilling machine. Background Art

[0002] Flange is also called flange or flange. Flange is a part that connects pipes to pipes and valves. It is connected to the pipe end. There are holes on the flange. Bolts connect the two flanges tightly. Gaskets are used to seal the flanges. Flanges are divided into threaded flanges, welding flanges and ferrule flanges.

[0008] As a preferred solution of the present invention, springs are fixedly installed at both ends of the lightweight scraper, and one end of the spring away from the lightweight scraper is fixedly connected to an inner wall of one side of the storage groove.

[0009] As a preferred solution of the present invention, a triangular plate is fixedly mounted on the middle part of the inner side surface of the chuck.

[0010] As a preferred solution of the present invention, a spring support plate is fixedly mounted on one end of the clamping slide bar away from the slide pin, and a return spring is fixedly mounted between the spring support plate and the guide pile seat.

[0011] As a preferred solution of the present invention, a pouring cavity is opened at the right end of the bottom wall of the narrow groove, and the pouring cavity passes through the interior of the guide frame and extends to the periphery of the bottom thereof.

[0012] As a preferred solution of the present invention, a drilling component is provided on the top of the guide frame, and the drilling component includes a drill platform. The drill platform is fixedly mounted on the periphery of the guide frame, and a downward pressure cylinder is fixedly installed on the top of the drill platform. The output shaft of the downward pressure cylinder is movably extended to the interior of the drill platform, and a multi-axis drilling rig is fixedly installed on the bottom of the output rod of the downward pressure cylinder. Twist drill bits are fixedly installed on the bottom output shaft ends of the multi-axis drilling rig, and a plurality of the twist drill bits are located at the middle upper end of the guide frame.

[0013] As a preferred solution of the present invention, the front and rear parts of the guide frame are fixedly installed with two left and right distributed support plates, and the bottoms of the support plates are fixedly installed with supporting square tubes, wherein the bottoms of the two front and rear supporting square tubes are jointly fixedly installed with a supporting bottom beam, and there are two supporting bottom beams in total, and the two supporting bottom beams are distributed left and right.

[0015] As a preferred solution of the present invention, a rubber buffer gasket is provided on the inner wall of the chuck.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the two sliding pins are moved closer to each other through the wedge force of the fishtail groove wall until the two sliding pins move from the inside of the fishtail groove to the inside of the narrow groove. During the movement of the two sliding pins closer to each other, the two clamping slides drive the two chucks to move closer to each other, and the flange blank located between the two chucks is firmly clamped, which can ensure that the flange will not shake laterally during the drilling process, thereby improving the accuracy of the drilling position, and the two triangular plates also apply a downward thrust to the flange, so that the bottom surface of the flange is tightly attached to the top of the front and rear two clamping slides, ensuring that the flange is in a completely flat state, so that multiple twist drill bits are at a vertical angle to the top surface of the flange, and the drilling is prevented from tilting.

[0018] 2. In the present invention, during the movement of the front and rear sliding pins toward each other, the front and rear receiving grooves approach each other together. Since the top walls of the receiving grooves are arranged in an angle, when the two receiving grooves approach each other, the top walls of the receiving grooves exert a downward wedge force on the top corners of the lightweight scraper, causing the lightweight scraper to slide downward along the inner walls of the receiving grooves. The two parts connected to the lightweight scraper are compressed and elastically bent downward. When the two sliding pins approach each other to the stop position, the bottom of the lightweight scraper just contacts the bottom wall of the narrow groove, so that the iron filings that fall into the narrow groove during the drilling process can be scraped away by the lightweight scraper. When the iron filings are scraped to the top of the pouring cavity, the iron filings fall off to the bottom of the guide frame through the pouring cavity under the action of gravity. This can avoid the accumulation of iron filings inside the narrow groove and the obstruction of the movement of the sliding pin.

[0019] 3. In the present invention, the front and rear sliding pins move away from each other and reset under the action of the rebound force of the two reset springs, resulting in the disappearance of the wedge force of the top wall of the storage groove on the top corner of the lightweight scraper. The rebound force generated by the bending action drives the lightweight scraper to move upward. It should be noted that the lightweight scraper is supported by a lightweight plastic part. Due to the upward movement of the lightweight scraper, the bottom of the lightweight scraper will not always contact with the inner wall of the wide groove or the narrow groove. In other words, the bottom of the lightweight scraper will not always contact and rub against the inner wall of the narrow groove or the inner wall of the wide groove, thereby avoiding excessive consumption of the lightweight scraper.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8 The technical solution provided by the present invention specifically includes the following embodiments: Embodiment 1

[0032] The feeding component includes two driving shafts 201 distributed on the left and right, and the driving shafts 201 are rotatably installed in the bearing hole 104. Two synchronous wheels 202 distributed front and back are fixedly installed on the outer walls of the two driving shafts 201, wherein a synchronous belt 203 is commonly sleeved between the two synchronous wheels 202 at the left and right positions, and the number of synchronous belts 203 is two, and the two synchronous belts 203 are respectively located at the front part of the guide frame 1 and the rear part of the guide frame 1, and a plurality of equally distributed guide pile seats 204 are fixedly installed on the outer surface of the synchronous belt 203, and a guide square groove 205 is penetrated through the side of the guide pile seat 204 close to the guide frame 1, and a clamping slide 206 is slidably installed in the guide square groove 205, and a sliding pin 208 is fixedly installed at the bottom of the clamping slide 206 close to the end of the guide frame 1, and the sliding pin 208 is slidably located in the wide groove 101 and the narrow groove 102, and a chuck 207 is fixedly installed on the top of the clamping slide 206, and a rubber buffer gasket is provided on the inner wall of the chuck 207;

[0033] A drilling component is provided on the top of the guide frame 1, and the drilling component includes a drilling platform 301, and the drilling platform 301 is fixedly mounted on the periphery of the guide frame 1, and a downward pressure cylinder 302 is fixedly installed on the top of the drilling platform 301, and the output shaft of the downward pressure cylinder 302 is movably extended to the inside of the drilling platform 301, and a multi-axis drilling machine 303 is fixedly installed at the bottom of the output rod of the downward pressure cylinder 302, and twist drill bits 304 are fixedly installed at the bottom output shaft ends of the multi-axis drilling machine 303, and multiple twist drill bits 304 are located at the middle upper end of the guide frame 1;

[0034] Two left and right supporting foot plates 106 are fixedly installed at the front and rear of the guide frame 1, and a supporting square tube 601 is fixedly installed at the bottom of each supporting foot plate 106, wherein a supporting bottom beam 602 is fixedly installed at the bottom of the two front and rear supporting square tubes 601, and there are two supporting bottom beams 602, and the two supporting bottom beams 602 are distributed left and right;

[0035] A protective cover 5 is fixedly provided on the periphery of the synchronous belt 203. The protective cover 5 is directly fixedly installed on the periphery of the supporting square tube 601. There are two protective covers 5, and the two protective covers 5 are symmetrically distributed front and back. A stepper motor 2011 is fixedly installed on the front left end of one of the protective covers 5. The output shaft end of the stepper motor 2011 is fixedly connected to the shaft end of one of the driving shafts 201 through a coupling.

[0036] Specifically, the output shaft of the stepper motor 2011 drives the drive shaft 201 connected thereto to rotate, further driving the two synchronous wheels 202 connected to the drive shaft 201 to rotate, and cooperates with the connection between another drive shaft 201 and the other two synchronous wheels 202 and two synchronous belts 203, resulting in the operation of the two synchronous belts 203. The rotation of the synchronous belt 203 drives the multiple guide pile seats 204, the clamping slide bar 206, the clamp head 207 and the sliding pin 208 connected thereto to rotate around the periphery of the guide frame 1. At this time, one of the flange blanks is positioned at The flange blank is placed on the top of the two front and rear clamping slides 206 in operation in sequence at the left part of the guide frame 1, and the flange blank is located between the two clamping heads 207 at the top of the two clamping slides 206, and moves to the right along the top of the guide frame 1 with the two clamping slides 206 and the clamping heads 207 in operation. At the same time, the two clamping heads 207 with the flange blank placed also drive the two sliding pins 208 to move together. At first, the two sliding pins 208 slide along the inner wall of the wide groove 101. When the two sliding pins 208 slide to the inside of the fishtail groove 103, the two sliding pins 208 continue to Move rightward, under the action of the wedge force of the groove wall of the fishtail groove 103, the two sliding pins 208 approach each other, until the two sliding pins 208 move from the inside of the fishtail groove 103 to the inside of the narrow groove 102. During the movement of the two sliding pins 208 approaching each other, the two clamping slides 206 drive the two clamping heads 207 to approach each other, and the flange blank located between the two clamping heads 207 is firmly clamped. During this period, the clamping slides 206 can ensure the stability of the movement of the two clamping slides 206 through the sliding installation effect with the guide square groove 205. The front and rear clamping of the flange blank by 207 can ensure that the flange will not shake sideways during the drilling process, thereby improving the accuracy of the drilling position. That is to say, when the clamped flange blank moves to the position directly below the multi-axis drilling rig 303, people turn off the stepper motor 2011, and start the downward pressure cylinder 302 and the multi-axis drilling rig 303 in succession. The multi-axis drilling rig 303 is pushed downward by the output rod of the downward pressure cylinder 302. The downward movement of the multi-axis drilling rig 303 drives multiple twist drill bits 304 to move downward together, and the flange blank directly below it is drilled.

[0037] Furthermore, a spring support plate 209 is fixedly installed at one end of the clamping slide 206 away from the sliding pin 208, and a return spring 2010 is fixedly installed between the spring support plate 209 and the guide pile seat 204. When the two clamping slides 206 move closer to each other, the two spring support plates 209 are also driven to move together, resulting in the two return springs 2010 being compressed and storing force. After the drilling is completed, the multi-axis drilling machine 303 is driven to move upward by the output rod of the downward-pressing cylinder 302, and the twist drill bit 304 is reset upward, and then the stepping motor 2011 is started again to make the multi-axis drilling machine 303 move upward. The flange with the drilled hole continues to move to the right along with the chuck 207 and the clamping slide 206. When it moves to the inside of the fishtail groove 103 located on the right part of the guide frame 1, the elasticity of the two return springs 2010 in the compressed state is gradually released, pushing the two spring support plates 209 to move away from each other. The two spring support plates 209 drive the two clamping slides 206 together with the two chucks 207 and the sliding pin 208 to move away from each other. The two chucks 207 move away from each other, thus releasing the clamping effect on the flange with the drilled hole, so that the processed flange can be taken out. Embodiment 2

[0038] The cleaning component includes a receiving groove 2081 provided inside the sliding pin 208, the top wall of the receiving groove 2081 is set as a 45° inclined surface, and the receiving groove 2081 runs through the bottom of the sliding pin 208, wherein a light scraper 2082 is slidably installed inside the two receiving grooves 2081 located at the front and rear;

[0039] Springs 2083 are fixedly installed at both ends of the light scraper 2082, and one end of the spring 2083 away from the light scraper 2082 is fixedly connected to an inner wall of one side of the receiving groove 2081;

[0040] A pouring channel 105 is formed at the right end of the bottom wall of the narrow groove 102. The pouring channel 105 penetrates the interior of the guide frame 1 and extends to the periphery of the bottom thereof.

[0041] Specifically, in this embodiment, when the front and rear sliding pins 208 move toward each other, the front and rear receiving grooves 2081 move toward each other. Since the top walls of the receiving grooves 2081 are set at 45 degrees, when the two receiving grooves 2081 move toward the middle, the top walls of the receiving grooves 2081 exert a downward wedge force on the top corners of the light scraper 2082, causing the light scraper 2082 to slide downward along the inner wall of the receiving groove 2081 and move with the light scraper 2082. The two connected 2023 are compressed and elastically bent downward. When the two sliding pins 208 approach each other to the stop point position, the bottom of the light scraper 2082 just contacts the bottom wall of the narrow groove 102, so that the iron filings that fall into the narrow groove 102 during the drilling process can be scraped away by the light scraper 2082. When the iron filings are scraped to the top of the pouring cavity 105, the iron filings fall off to the bottom of the guide frame 1 through the pouring cavity 105 under the action of gravity. In this way, it can be avoided that the iron filings accumulate inside the narrow groove 102 and cause the movement of the sliding pin 208 to be blocked. When the sliding pin 208 moves from the inside of the narrow groove 102 to the inside of the wide groove 101 located at the top right end of the guide frame 1, the front and rear sliding pins 208 move away from each other under the action of the rebound force of the two reset springs 2010 and reset, resulting in the wedge force of the top wall of the receiving groove 2081 on the top angle of the light scraper 2082 disappearing, and the bending effect of 223 produces The rebound force drives the lightweight scraper 2082 to move upward. It should be noted that the lightweight scraper 2082 is supported by a lightweight plastic part. Due to the upward movement of the lightweight scraper 2082, the bottom of the lightweight scraper 2082 will not always be in contact with the inner wall of the wide groove 101 or the narrow groove 102. In other words, the bottom of the lightweight scraper 2082 will not always be in contact and friction with the inner wall of the narrow groove 102 or the inner wall of the wide groove 101, thereby avoiding excessive consumption of the lightweight scraper 2082. Embodiment 3

[0042] A triangle plate 2012 is fixedly mounted on the middle part of the inner side surface of the clamp 207;

[0043] Specifically, in this embodiment, due to the triangular setting of the triangular plate 2012, when the chuck 207 clamps the flange, it drives the front and rear triangular plates 2012 to approach each other, causing the bottom inclined surfaces of the two triangular plates 2012 to abut against the upper outer wall of the flange, thereby generating a downward wedge force on the flange. While the two chucks 207 apply front and rear clamping forces to the flange, the two triangular plates 2012 also apply a downward thrust to the flange, so that the bottom surface of the flange is tightly attached to the top of the front and rear clamping slides 206, ensuring that the flange is in a completely flat state, so that the multiple twist drill bits 304 are at a vertical angle to the top surface of the flange, avoiding tilting of the drilling holes.

[0044] When the flange automatic drilling machine of the present invention is working, the stepper motor 2011 is started, and the output shaft of the stepper motor 2011 drives the drive shaft 201 connected thereto to rotate, further driving the two synchronous wheels 202 connected to the drive shaft 201 to rotate, and cooperates with the connection between another drive shaft 201 and the other two synchronous wheels 202 and the two synchronous belts 203, so that the two synchronous belts 203 are in operation;

[0045] The synchronous belt 203 rotates and drives the multiple guide pile seats 204, clamping slides 206, chucks 207 and sliding pins 208 connected thereto to rotate around the periphery of the guide frame 1. At this time, one of the flange blanks is located at the left part of the guide frame 1 and is placed on the top of the two front and rear clamping slides 206 that are in operation. At the same time, the flange blank is located between the two chucks 207 on the top of the two clamping slides 206, and moves to the right along the top of the guide frame 1 with the two running clamping slides 206 and chucks 207. At the same time, the two chucks 207 with the flange blanks placed also drive the two sliding pins 208 to move together. At first, the two sliding pins 208 slide along the inner wall of the wide groove 101. When the two The two sliding pins 208 slide into the inside of the fishtail groove 103, and the two sliding pins 208 continue to move to the right. Under the wedge force of the groove wall of the fishtail groove 103, the two sliding pins 208 approach each other until the two sliding pins 208 move from the inside of the fishtail groove 103 to the inside of the narrow groove 102. During the movement of the two sliding pins 208 approaching each other, the two clamping slides 206 drive the two clamping heads 207 to approach each other, and the flange blank located between the two clamping heads 207 is firmly clamped. During this period, the clamping slides 206 can ensure the stability of the movement of the two clamping slides 206 through the sliding installation effect with the guide square groove 205, and when the two clamping slides 206 approach each other, they also drive the two The spring support plate 209 moves together, causing the two return springs 2010 to be compressed and accumulate force. Since the two chucks 207 clamp the flange blank front and back, it can ensure that the flange will not shake sideways during the drilling process, thereby improving the accuracy of the drilling position. That is to say, when the clamped flange blank moves to the position directly below the multi-axis drilling rig 303, people turn off the stepper motor 2011, and start the downward pressure cylinder 302 and the multi-axis drilling rig 303 in succession, and the multi-axis drilling rig 303 is pushed downward by the output rod of the downward pressure cylinder 302. The downward movement of the multi-axis drilling rig 303 drives multiple twist drill bits 304 to move downward together, and the flange blank directly below it is drilled. After the drilling is completed, the downward pressure cylinder 302 is used to push the multi-axis drilling rig 303 downward. The output rod of the air pressure cylinder 302 drives the multi-axis drilling machine 303 to move upward, resets the twist drill bit 304 upward, and then starts the stepper motor 2011 again, so that the flange with the completed hole continues to move to the right along with the chuck 207 and the clamping slide 206. When it moves to the inside of the fishtail groove 103 located on the right part of the guide frame 1, the elasticity of the two return springs 2010 in the compressed state is gradually released, pushing the two spring support plates 209 to move away from each other. The two spring support plates 209 drive the two clamping slides 206 together with the two chucks 207 and the sliding pin 208 to move away from each other. The two chucks 207 move away from each other, and the clamping effect on the flange with the completed hole is released, so that the processed flange can be taken out;

[0046] As the front and rear sliding pins 208 move toward each other, the front and rear receiving grooves 2081 approach each other together. Since the top walls of the receiving grooves 2081 are set at 45 degrees, when the two receiving grooves 2081 approach the middle, the top walls of the receiving grooves 2081 exert a downward wedge force on the top angle of the lightweight scraper 2082, causing the lightweight scraper 2082 to slide downward along the inner wall of the receiving groove 2081, and the two 2023 connected to the lightweight scraper 2082 are compressed and elastically bent downward. When the two sliding pins 208 approach each other to the stop point position, the bottom of the lightweight scraper 2082 just contacts the bottom wall of the narrow groove 102, so that the iron filings that fall into the narrow groove 102 during the drilling process can be scraped away by the lightweight scraper 2082. When the iron filings are scraped to the top of the pouring cavity 105, the iron filings fall off to the bottom of the guide frame 1 through the pouring cavity 105 under the action of gravity. This can avoid Iron filings accumulate inside the narrow groove 102, causing the movement of the sliding pin 208 to be blocked. When the sliding pin 208 moves from the inside of the narrow groove 102 to the inside of the wide groove 101 located at the top right end of the guide frame 1, the front and rear sliding pins 208 move away from each other and reset under the action of the rebound force of the two reset springs 2010, resulting in the wedge force of the top wall of the storage groove 2081 on the top corner of the lightweight scraper 2082 disappearing. The rebound force generated by the bending action of 2023 drives the lightweight scraper 2082 to move upward. It should be noted that the lightweight scraper 2082 is supported by a lightweight plastic part. Due to the upward movement of the lightweight scraper 2082, the bottom of the lightweight scraper 2082 will not always contact with the inner wall of the wide groove 101 or the narrow groove 102. In other words, the bottom of the lightweight scraper 2082 will not always contact and rub against the inner wall of the narrow groove 102 or the inner wall of the wide groove 101, thereby avoiding excessive consumption of the lightweight scraper 2082.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
