Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and in particular, to a numerical control machine tool for pipe thread processing. Background Art

[0002] In the manufacturing of industrial instruments or industrial devices, connecting pipes are required to connect different components. When connecting pipes, pipe threads are needed to ensure the sealing performance of the connection.

[0003] When workers process pipe threads for pipes, they need to select a suitable tool bit according to the diameter of the pipe and the processing standard of the thread, and install the tool bit on the tool disc of the cutting machine. Subsequently, the cutting machine is used to drive the pipe to rotate and cooperate with the tool bit to process the pipe thread. Since the diameters of the pipes are different and there are different size standards, there are numerous tool bits for processing pipe threads. When processing different pipe threads, workers need to continuously replace the tool bits with corresponding specifications or corresponding thread size standards. On the premise that different pipes need to be manually installed on the numerical control machine tool, installing the tool bit again will affect the efficiency of pipe thread processing. Moreover, the tool bit is usually installed on the tool disc with bolts, and removing and installing the tool bit will also consume a certain amount of time, further affecting the efficiency of pipe thread processing and being unfavorable to the economic benefits of pipe processing.

A chuck is rotatably connected to the side of the fixed box close to the bed body. A first pulley is fixedly connected to the outer arc surface of the chuck. A second motor is fixedly installed on the top of the fixed box. A second pulley is fixedly connected to the output shaft of the second motor. A belt is sleeved on the first pulley and the second pulley. A plurality of jaws are slidably connected to the chuck at equal intervals in the circumferential direction.

[0018] As described above, the characteristics and advantages of a pipe thread processing numerical control machine tool in the present invention are:

[0019] By providing a plurality of jacks on the tool disc, the pin at one end of the cutting tool is aligned with the jack and inserted, so that the second block and the inclined surface of the first block cooperate to push the sliding plate until the pin contacts the inner wall of the jack and cannot be pushed further, and the cutting tool is installed, achieving the effect of rapid installation of the cutting tool. And a plurality of tool heads can be installed to install the required tool heads on the tool disc at one time according to the corresponding specifications and dimensional standards during this pipe thread processing, without frequently disassembling and assembling the tool heads, saving time and effort;

[0020] Through the cooperation of the jaws driving the push plate and the arc-shaped plate, when the jaws slide towards the inside of the chuck, several press switches are sequentially ejected during the process of the sliding rod sliding out of the fixed cylinder. The smaller the diameter of the pipe, the more press switches are ejected. The corresponding number of press switches is ejected according to the diameter of the pipe, and according to the number of ejected press switches, the first motor drives the disc to rotate a corresponding number of turns to rotate the cutting tool corresponding to the pipe diameter to be perpendicular to the pipe, achieving the effect of tool head self-adaptation. There is no need for workers to manually switch the corresponding tool head to the tool disc after comparing the cutting specifications, improving the efficiency of tool head switching;

[0021] Through the cooperation of the shifting groove and the shifting rod, the sliding rod slides out of the fixed cylinder so that the push-type switches pop out one by one. Every time a push-type switch pops out, the motor 1 drives the wheel on the output shaft to rotate one circle, and the action of the shifting fixed pin 2 drives the fixed disk and the turntable to rotate 22.5 degrees. The fixed pin 1 cooperates with the limit of the shifting groove to make the turntable rotate 22.5 degrees again. At this time, the shifting rod has not yet touched the fixed pin 2, and the turntable has rotated 45 degrees. Therefore, the slide 2 drives the cutter disc to rotate 45 degrees, so that different cutting knives are switched to be perpendicular to the pipe.

[0022] Through the cooperation of clamp block one and clamp block two, when the cutting knife needs maintenance and replacement, the worker pinches the cutting knife and pulls the cutting knife toward the outside of the cutter disc. As the cutting knife is pulled outward, clamp block two repeatedly squeezes clamp block one until the pin slides out of the socket, thereby realizing the rapid disassembly of the cutting knife. It is convenient for the worker to quickly remove the cutting knife and perform the operation of sharpening or changing the knife, thereby improving the efficiency of daily maintenance and the efficiency of replacing multiple cutting knives of corresponding specifications after switching to pipes of different specifications.

[0042] Further, as Figure 1 、 Figure 2 、 Figures 8 to 10 ​As shown, an induction component is provided on the top side of the bed 1, and the induction component includes a fixed box 601 fixedly connected to one side of the bed 1, and a chuck 602 is rotatably connected to the side of the fixed box 601 close to the bed 1. A through hole is opened on the fixed box 601 and aligned with the middle of the chuck 602. The outer arc surface of the chuck 602 is fixedly connected to the pulley 1 603, and the top of the fixed box 601 is fixedly installed with the motor 2 604. The output shaft of the motor 2 604 is fixedly connected to the pulley 2 605. The pulley 1 603 and the pulley 2 605 are provided with a belt, and the two are in transmission cooperation. A plurality of claws 606 are equidistantly connected to the chuck 602 in an annular manner. An adjusting bolt for controlling the movement of the claw 606 is provided on the chuck 602. The adjusting bolt drives the threaded disk in the chuck 602 to rotate, and then the threaded disk cooperates with the teeth on the claw 606 to drive the plurality of claws 606 to slide synchronously in the sliding groove of the chuck 602. This is a prior art and is not repeated here. As described above, a push plate 607 is fixedly connected to the side of the multiple claws 606 away from the chuck 602, and a fixing ring 608 is fixedly connected to the fixing box 601. Sliding rods 609 are slidably connected to both sides of the fixing ring 608. An arc plate 610 is fixedly connected to the end of the sliding rod 609 close to the chuck 602.

A plurality of chip grooves 8 are equidistantly provided on the top of the bed 1, and the bottom ends of the plurality of chip grooves 8 lead to the side of the bed 1 away from the linear module 2. The metal chips cut off by the cutting tool 406 can be discharged to the side of the bed 1 through the chip groove 8 to avoid the accumulation of metal chips.

[0044] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0045] The initial state is:

[0046] The pins 405 fixedly connected to eight cutting tools 406 of different specifications are respectively inserted into the jacks 404. The first spring 412 is in a stretched state. The sliding plate 409 is located on the side of the second sliding groove 408 close to the jack 404. The second catch 411 abuts against the first catch 410 adjacent to it. The first motor 505 and the second motor 604 are not powered on. The jaw 606 is located on the side of the chuck 602 groove close to the fixed ring 608. The push plate 607 abuts against the arc-shaped plate 610. The second spring 611 is in a compressed state. The end of the sliding rod 609 close to the fixed cylinder 612 abuts against the inner wall of the fixed cylinder 612. All the push-button switches 613 are in a compressed state.

[0047] The working state is as follows:

[0048] Install the pipe:

[0049] After inserting the pipe into the fixed box 601 from the center of the chuck 602, the worker uses a T-shaped wrench to turn the adjusting bolt on the chuck 602, causing the jaw 606 to slide towards the middle of the chuck 602, gradually approaching the pipe, and clamping the pipe between the fixed box 601 and the middle of the chuck 602 with the cooperation of multiple jaws 606. Subsequently, the worker rotates the handle on the tailstock 7 to move it towards the direction close to the fixed box 601, so that the tailstock 7 abuts against one end of the pipe, thus realizing the installation of the pipe.

[0050] Adaptive adjustment:

[0051] When the jaw 606 slides towards the center point of the chuck 602, the push plate 607 on one side of the chuck 602 synchronously approaches the center point of the chuck 602 driven by the jaw 606. During this process, the distance that the push plate 607 presses the arc-shaped plate 610 gradually decreases, causing the second spring 611 to stretch and continuously push the arc-shaped plate 610 towards the push plate 607. Thus, the inner arc surface of the arc-shaped plate 610 continues to abut against the outer arc surface of the push plate 607. When the arc-shaped plate 610 gradually approaches the chuck 602, the sliding rod 609 gradually slides out of the fixed cylinder 612 driven by the arc-shaped plate 610, causing several push-button switches 613 to pop out in sequence during the process of the sliding rod 609 sliding out of the fixed cylinder 612. Subsequently, after the jaw 606 compresses the pipe and stops sliding, the push plate 607, the arc-shaped plate 610, and the sliding rod 609 stop synchronously. The smaller the diameter of the pipe, the more push-button switches 613 pop out. Thus, the corresponding number of push-button switches 613 is popped out according to the diameter of the pipe, achieving the adaptive effect.

[0052] Tool head self-adaptation:

[0053] When the sliding rod 609 slides out of the fixed cylinder 612 and the push-type switches 613 pop out one by one, each time a push-type switch 613 pops out, the controller controls the motor 1 505 to drive the wheel disc 506 on the output shaft to rotate one circle, so that the wheel disc 506 drives the dial rod 508 to rotate one circle. During this process, the dial rod 508 first contacts the fixed pin 2 504 under the drive of the wheel disc 506, and then drives the fixed disc 503 and the turntable 501 to rotate 22.5 degrees under the action of the dial fixed pin 2 504. Then, the dial rod 508 rotates in the direction away from the fixed pin 2 504 under the drive of the wheel disc 506 and no longer contacts the fixed pin 2 504. The wheel disc 506 continues to rotate, and then the dial slot 507 first contacts the fixed pin 1 502. Under the limit cooperation between the fixed pin 1 502 and the dial slot 507 , the wheel 506 continues to drive the turntable 501 to rotate until the driving slot 507 is driven by the wheel 506 to gradually rotate away from the fixed pin 1 502 and disconnect them from each other, so that the turntable 501 rotates 22.5 degrees again. At this time, the lever 508 has not yet contacted the fixed pin 2 504, and the turntable 501 rotates forty-five degrees, so that the slide 2 401 drives the cutter disc 403 to rotate forty-five degrees, thereby achieving the effect of switching different cutting knives 406 to be perpendicular to the pipe, and according to the number of pop-up push-type switches 613, the motor 1 505 drives the wheel 506 to rotate the corresponding number of circles, so as to rotate the cutting knife 406 corresponding to the pipe diameter to be perpendicular to the pipe, so as to achieve the effect of self-adaptation of the cutter head, and there is no need for workers to manually switch the corresponding cutter head to the cutter disc 403 after checking the cutting specifications, which saves time and effort.

[0054] Rotary thread processing:

[0055] When the pipe is installed and the corresponding cutting tool 406 is perpendicular to the pipe, motor 2 604 is started, and motor 2 604 drives pulley 2 605 to rotate. Pulley 2 605 rotates through belt drive pulley 1 603, thereby driving chuck 602 to rotate, and then driving the pipe fixed in the middle of chuck 602 to rotate. Then, with the cooperation of linear module 2 and slide 1 3, the cutting tool 406 on the top of slide 1 3 is controlled to translate and feed, so that chuck 602 rotates with the pipe and cooperates with the cutting tool 406 on the top of slide 1 3 to process the pipe thread. In the process of chuck 602 rotating to drive pulley 1 603 and push plate 607 to rotate, since there are multiple push plates 607, push plate 607 always has a resistance effect on arc plate 610 when rotating, so it does not affect the sliding of sliding rod 609, thereby ensuring that the cutting tool 406 is adaptively aligned with the pipe while not interfering with the operation of rotating chuck 602 to process the thread.

[0056] Quick disassembly of the cutter head:

[0057] When processing threads of uncommon specifications or when the cutting tool 406 needs to be maintained or replaced, the worker pinches the cutting tool 406 and pulls the cutting tool 406 outward from the cutter head 403, causing the cutting tool 406 to drive the plug 405 to slide outward from the jack 404. As a result, the inclined surface of the second block 411 continuously pushes the first block 410, causing the first block 410 to push the sliding plate 409 to slide towards the side away from the jack 404 in the second sliding groove 408 and compress the first spring 412. Subsequently, when the second block 411 slides between the two first blocks 410, the first spring 412 extends again to push the sliding plate 409 towards the jack 404, causing the first block 410 to reset and catch the second block 411 again. Subsequently, under the action of the worker pulling the cutting tool 406 outward, the second block 411 repeatedly squeezes the first block 410 until the plug 405 slides out of the jack 404, realizing the quick disassembly of the cutting tool 406. During installation, the plug 405 at one end of the cutting tool 406 to be replaced is aligned with the jack 404 and inserted, causing the second block 411 to cooperate with the inclined surface of the first block 410 to push the sliding plate 409 until the plug 405 contacts the inner wall of the jack 404 and cannot be pushed further, and the cutting tool 406 is installed, achieving the effect of quick installation of the cutting tool 406, thereby facilitating the replacement and maintenance of the cutting tool 406 and making it more convenient to use.

[0058] The above are only embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
