DETAILED DESCRIPTION

[0032] 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.

[0033] For example, see Figure 1-Figure 4 The present invention provides a technical solution: a CNC drilling machine for pipe processing, comprising a work box 1, a mounting seat 2 is fixedly connected to the top of the work box 1, a CNC box 3 is fixedly connected to the top of the mounting seat 2, a telescopic frame 4 is slidably connected to the inner wall of the CNC box 3, a telescopic column is fixedly connected to the bottom of the telescopic frame 4, and the model of the telescopic column is a corrugated telescope, which is mainly used to compensate for axial displacement, has a relatively simple structure, and is composed of a corrugated tube and a connecting end. The cutting tool can be driven to move downward to the surface of the pipe through the telescopic column, a slide 5 is fixedly connected to the right side of the inner wall of the work box 1, and a mounting mechanism 6 is arranged on the surface of the slide 5, and also includes:

[0034] One end of the telescopic rod 602 away from the mounting plate 601 is fixedly connected to one end of the mounting plate 601 and the bottom of the transmission block 608. A magnetic ring is installed on the top of the transmission block 608. The telescopic rod 602 is used to pull the transmission block 608. First, one end of the pipe is placed on the inner wall of the mounting plate 601. By pushing the mounting plate 601, one end of the telescopic rod 602 on the surface of the mounting plate 601 is extended and retracted on the inner wall of the mounting pad 603. When the end of the pipe away from the mounting plate 601 contacts the surface of the clamping plate 604.

[0035] Inside the offset plate 6073, there is an expander. The model of the expander is a corrugated expander, which is mainly used to compensate for axial displacement. It has a relatively simple structure and consists of a bellows and a connection end. The offset plate 6073 can drive the compression rod 6074 to slide inward. The extrusion rod 6076 has the property of expansion and contraction. This offset plate 6073 is used to fix the inner wall of the pipe. One end of the inner wall of the pipe will come into contact with the surface of the resistance block 6075. Then, by remotely starting the expander inside the inner wall of the offset plate 6073 to drive the compression rod 6074 to slide inward. When the compression rod 6074 drives the offset plate 6073 to expand and contract inward to the surface of the pipe, the offset plate 6073 and the resistance block 6075 are used to clamp and fix one end of the pipe, and different models of pipes can be fixed first to meet the cutting conditions.

[0036] The installation mechanism 6 includes an installation disk 601. The installation disk 601 is slidably connected to the surface of the sliding table 5. A telescopic rod 602 is fixedly connected to the left side of the installation disk 601. The bottom of the inner wall of the working box 1 is fixedly connected with an installation pad 603. The top of the installation pad 603 is fixedly connected with a clamping disk 604. An expansion mechanism 7 is arranged inside the inner wall of the clamping disk 604. An installation ring 605 is fixedly connected to the surface of the clamping disk 604. One end of the transfer pipe 801 far from the transfer frame 802 is fixedly connected to the inner wall of the installation ring 605. A transmission ring 606 is fixedly connected to the inner wall of the installation ring 605. A clamping assembly 607 is arranged at one end of the transmission ring 606 far from the installation ring 605. The end of the telescopic rod 602 far from the installation disk 601 is slidably connected to the inner wall of the installation pad 603. A transmission block 608 is slidably connected to the top slot of the installation pad 603. This installation disk 601 is used to push the telescopic rod 602. When the offset plate 6073 drives the compression rod 6074 to slide inward, it will compress one end of the extrusion rod 6076, so that the compression rod 6074 compresses inward and generates air pressure and discharges it into the folding ring 6071. Then, the air pressure inside the folding ring 6071 is introduced into the installation ring 605 through the transmission ring 606, and the air pressure is discharged into the transfer pipe 801 through the installation ring 605.

[0037] The clamping assembly 607 includes a folding ring 6071, which is fixedly connected to one end of the transmission ring 606. Both ends of the folding ring 6071 are fixedly connected to sliding tubes 6072. One end of the sliding tube 6072 is slidably connected to the surface slot of the clamping disk 604. The end of the sliding tube 6072 away from the clamping disk 604 is fixedly connected to a bias plate 6073. The right side of the bias plate 6073 is fixedly connected to an extrusion rod 6076. The top of the bias plate 6073 is fixedly connected to a compression rod 6074, and the compression rod 6074 is away from the bias plate. One end of 6073 is fixedly connected to a resistance block 6075, and one end of an extrusion rod 6076 away from the biasing plate 6073 is fixedly connected to the surface of the resistance block 6075. The extrusion rod 6076 is used to transmit the air pressure to the outside. When the wall thickness of the pipe changes, the degree of bending and stretching of the extrusion rod 6076 inward will also change, so that the amount of air pressure generated inside the extrusion rod 6076 will also change. The cutting radius of the cutting tool can be set and adjusted according to the pipes with different wall thicknesses to meet the cutting conditions of different types of pipes.

[0038] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6 The telescopic mechanism 7 includes a telescopic disc 701, which is fixedly connected to the inner wall of the clamping disc 604. The inner wall of the clamping disc 604 is fixedly connected to a support rod 702. The end of the support rod 702 away from the telescopic disc 701 is fixedly connected to a telescopic cavity 703. The support rod 702 is used to support the telescopic cavity 703. When the model of the pipe is changed and the length of the pipe is increased, the mounting disc 601 needs to be pulled outward, and the telescopic rod 602 is pulled out from the inside of the mounting pad 603 during the pulling process. The transmission will be driven during the pulling process. Block 608 slides outward at the top slot of the mounting pad 603, and the transmission block 608 generates a magnetic attraction effect with the adsorption block 7043 on the inner wall of the tube during the sliding process, thereby pulling the connecting frame 7042 outward through the magnetic effect generated between the adsorption block 7043 and the transmission block 608. When the connecting frame 7042 is pulled outward, the telescopic tube 7041 is pulled out from the inner wall of the telescopic cavity 703. When the telescopic tube 7041 slides from the inner wall of the telescopic cavity 703, the support arm 7046 on its surface is extended and retracted outward.

[0039] The support film 7044 has the property of being able to expand and contract inside and outside. A magnetic block is installed at the bottom of the adsorption block 7043. The support film 7044 is used to push the support arm 7046. Since a plurality of support arms 7046 are installed on the inner wall of the telescopic cavity 703, after the support arm 7046 is pulled out from the inside of the telescopic cavity 703 through the telescopic tube 7041, the support film 7044 on the surface of the support arm 7046 will expand and contract outward due to the external pulling, thereby supporting and fixing the plurality of support arms 7046. Since the plurality of support films 7044 expand and contract outward, the support film 7044 will discharge the internal compressed gas into the internal transmission hole of the support arm 7046 due to the external stretching, thereby pushing the support ring 7045.

[0040] The support assembly 704 includes a telescopic tube 7041 slidably connected to the inner wall of the telescopic cavity 703, a support arm 7046 is fixedly connected to the surface of the telescopic tube 7041, a support ring 7045 is slidably connected to the surface of the support arm 7046, a support membrane 7044 is fixedly connected to the left side of the support arm 7046, a connecting frame 7042 is provided at the end of the telescopic tube 7041 away from the telescopic cavity 703, an adsorption block 7043 is fixedly connected to the bottom of the connecting frame 7042, and the adsorption block 7043 is used to generate a magnetic attraction reaction with the transmission block 608, driving the support ring 7045 to extend and retract outward from the surface slot of the support arm 7046, and the inner wall of the pipeline is fixed by multiple support rings 7045. When replacing different types of pipes for processing and cutting, the inside of different types of pipes can be fixed in a targeted manner to improve the stability of the surface cutting of the pipe.

[0041] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8 The transmission mechanism 8 includes a connecting seat 803 fixedly connected to the bottom of the telescopic column, and the two sides of the connecting seat 803 are fixedly connected to the transmission frame 802. The inner wall of the transmission frame 802 is fixedly connected to the transmission tube 801, and the transmission tube 801 is used to transmit the air pressure into the transmission frame 802. When the extrusion rod 6076 moves inward and the air pressure is introduced into the interior of the transmission frame 802 through the transmission tube 801, the air pressure will be discharged into the cutting disk 8041 through the transmission frame 802.

[0042] The cutting assembly 804 includes a cutting disk 8041 which is rotatably connected to the inner walls of the connecting seat 803 on both sides through a rotating shaft. The inner wall of the cutting disk 8041 is slidably connected to a stretching bar 8042 through a slider. The stretching bar 8042 is arranged on both sides of the inner wall of the cutting disk 8041. The surface of the stretching bar 8042 is fixedly connected to an expansion plate 8043. The bottom of the inner wall of the expansion plate 8043 is fixedly connected to a cutting tooth 8044. The expansion plate 8043 is used to increase the contact surface of the cutting disk 8041 with the pipe. The air pressure flows into the air pressure groove on the inner wall of the cutting disk 8041, thereby pushing the stretching bar 8042, so that the stretching bar 8042 slides outward from the inner wall of the cutting disk 8041. When the stretching bar 8042 slides outward, it will drive the expansion plate 8043 to retract outward from the inner wall of the cutting disk 8041, and the expansion plate 8043 will increase the contact surface of the cutting disk 8041 with the pipe when it retracts outward.

[0043] An air pressure groove is provided on the inner wall of the cutting disk 8041, and the air pressure groove is slidably connected to the surface of the stretching bar 8042. The stretching bar 8042 is used to push the expansion plate 8043. The pipe is cut by multiple cutting teeth 8044 on the inner wall of the cutting disk 8041. When cutting pipes of different types, the cutting radius of the cutting disk 8041 can be automatically adjusted to adapt to the cutting of pipes with different wall thicknesses. There is no need to change the pipe model and the cutting tool needs to be replaced in time to improve processing efficiency.
