Description

Technical Field

[0001] The present disclosure relates to the technical field of pipe processing, and particularly relates to a punching auxiliary device and a laser punching device. Background Art

[0002] In the photovoltaic industry or the semiconductor industry, it is necessary to perform deposition coating or other processes through a chemical vapor deposition furnace. In order to ensure that special gases inside can quickly diffuse to all regions of the furnace cavity, a plurality of air holes need to be processed on the gas transmission pipes inside the furnace. The cleanliness requirements of the air holes are high, and there should be no any residue inside the pipes.

[0003] In the related art, a drill press or a milling machine is usually used for drilling. During the drilling process, cutting fluid needs to be continuously sprayed on the drill bit. On the one hand, it flushes and discharges chips, and on the other hand, it cools the drill bit. And later, manual processing of the residue inside is required, which is very time-consuming and laborious. Moreover, when drilling small holes, the drill bit is extremely easy to break, and the processing speed is slow. For this reason, laser cutting is also used for punching in the related art. However, the waste residues generated by punching in the way of laser cutting are likely to remain in the gas transmission pipes and must be manually processed and then undergo multiple processes such as pickling and degreasing.

[0040] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present disclosure.

[0041] Figure 1 The figure shows a schematic diagram of a laser drilling device in the prior art in the working state. A drill press or a milling machine is used to drill holes in the pipe 100 to be processed. During the drilling process, cutting fluid needs to be continuously sprayed on the drill bit. On the one hand, it flushes and discharges chips, and on the other hand, it cools the drill bit. And later, manual treatment of the residues inside is required, which is very time - consuming and labor - intensive. Although laser drilling is also used in the prior art, the same slag discharge problem still exists. The drilling auxiliary device and the laser drilling device provided in this embodiment are intended to solve the above problems.

[0042] Next, a description will be given of the drilling auxiliary device in the embodiments of the present disclosure in conjunction with Figures 2 to 11 Among them,Figure 3 and Figure 4 The arrows of Figure 4 indicate the air flow direction.

[0043] The punching auxiliary device of this embodiment is applied to the punching process of the pipe 100 to be processed by a laser punching device. The pipe 100 to be processed has a plurality of punching positions 101 to be punched. For example, the plurality of punching positions 101 to be punched are arranged at intervals along the axial direction of the pipe 100 to be processed. Punching operations need to be performed at each punching position 101 to be punched.

[0044] Combined with Figure 2 and Figure 3 The punching auxiliary device includes an auxiliary pipe 200. The auxiliary pipe 200 is detachably inserted into the pipe 100 to be processed. At least one end of the auxiliary pipe 200 extends to the outside of the pipe 100 to be processed. Preferably, the length of the auxiliary pipe 200 is greater than the length of the pipe 100 to be processed, so that one end of the auxiliary pipe 200 is flush with one end of the pipe 100 to be processed, and the other end extends to the outside of the pipe 100 to be processed. Or, both ends of the auxiliary pipe 200 extend to the outside of the pipe 100 to be processed.

[0045] The auxiliary pipe 200 is provided with a plurality of auxiliary holes 201. The plurality of auxiliary holes 201 are respectively aligned with the plurality of punching positions 101 to be punched. The alignment direction is the radial direction of the pipe 100 to be processed and the auxiliary pipe 200. The aperture of the auxiliary hole 201 is slightly larger than the aperture of the hole to be punched, or the aperture of the auxiliary hole 201 is equal to the aperture of the hole to be punched. When the auxiliary pipe 200 is inserted into the pipe 100 to be processed, the outer wall of the auxiliary pipe 200 fits with the inner wall of the pipe 100 to be processed, or there is a small gap between the outer wall of the auxiliary pipe 200 and the inner wall of the pipe 100 to be processed. Optionally, the inner diameter φA of the pipe 100 to be processed and the outer diameter φB of the auxiliary pipe 200 satisfy: φA - φB = -0.1 mm - 0.5 mm.

[0046] In this embodiment, by setting the auxiliary pipe 200, the waste residue generated by punching the pipe 100 to be processed can enter the auxiliary pipe 200 through the auxiliary holes 201, and will not remain in the pipe 100 to be processed. Therefore, the difficulty of cleaning the pipe 100 to be processed can be effectively reduced. The auxiliary pipe 200 and the pipe 100 to be processed can be disassembled, which can facilitate the removal of the auxiliary pipe 200 for repeated use. When there is a large amount of waste residue in the auxiliary pipe 200, it is also convenient to clean the auxiliary pipe 200.

[0047] Combined with Figure 3 and Figure 4The punching auxiliary device also includes a purge mechanism 600, which has an air outlet end. The purge mechanism 600 supplies airflow to the auxiliary tube 200 through the air outlet end. Specifically, the air outlet end is aligned with one end of the auxiliary tube 200. The purge mechanism 600 supplies airflow to the inner hole of the auxiliary tube 200 through the air outlet end, so that the waste residue generated during the punching process of the tube 100 to be processed enters the auxiliary tube 200 and can be blown out under the action of the airflow supplied by the purge mechanism 600, thereby avoiding a large amount of waste residue remaining in the auxiliary tube 200 to affect the punching effect.

[0048] Combination Figure 4 Optionally, the purge mechanism 600 is also used to supply air flow into the tube to be processed 100 through the air outlet end. Specifically, after the auxiliary tube 200 is pulled out of the tube to be processed 100, the air outlet end can be aligned with the tube to be processed 100, so that the tube to be processed 100 can be purged by the purge mechanism 600.

[0049] Optionally, the purging mechanism 600 includes an air source (not shown in the figure), a connecting pipe 610 and a nozzle 620. The air source can be a compressor or a high-pressure gas storage tank, etc. In this embodiment, the gas pressure supplied by the air source is greater than or equal to 10 bar. One end of the connecting pipe 610 is connected to the air source, and the other end is connected to the nozzle 620. The gas supplied by the air source reaches the position of the nozzle 620 through the connecting pipe 610. The connecting pipe 610 is a flexible pipe, which can facilitate the arrangement of the air source position and the nozzle 620 position. The end of the nozzle 620 that is away from the connecting pipe 610 is the gas outlet end, and the outer diameter of the gas outlet end of the nozzle 620 is less than or equal to the inner diameter of the auxiliary pipe 200, so that the gas flowing out of the nozzle 620 is better gathered and enters the auxiliary pipe 200 or the pipe 100 to be processed. When purging, the nozzle 620 can be fixed in position by a structure such as a fixing clamp, or it can be fixed by plugging and matching with the auxiliary pipe 200 or the pipe 100 to be processed, which is not specifically limited here.

[0050] Combination Figure 5 The punching auxiliary device also includes a cleaning mechanism 700, which includes a rotary drive source 710 and a cleaning piece connected to the rotary drive source 710. The cleaning piece has a first state in which it is connected and matched with the tube 100 to be processed and a second state in which it is separated from the tube 100 to be processed. In the first state, the cleaning piece contacts and matches with the inner wall of the tube 100 to be processed, and the rotary drive source 710 is configured to drive the cleaning piece to rotate. The cleaning mechanism 700 is mainly used to clean a small amount of burrs in the tube 100 to be processed after the punching is completed. Specifically, after the auxiliary tube 200 is moved out of the tube 100 to be processed, the cleaning piece is switched to the first state. At this time, the cleaning piece is driven to rotate by the rotary drive source 710 to clean the inner wall of the tube 100 to be processed.

[0051] Optionally, the rotation driving source 710 includes a rotation motor, and the cleaning member includes a connecting handle 720 and bristles 730. One end of the connecting handle 720 is detachably connected to the output shaft of the rotation motor. For example, the output shaft of the rotation motor is provided with a drill chuck or a chuck to achieve the detachable connection between one end of the connecting handle 720 and the output shaft of the rotation motor. The bristles 730 are fixedly arranged at one end of the connecting handle 720 facing away from the rotation motor, and in the first state, the bristles 730 are in contact and cooperation with the inner wall of the pipe 100 to be processed.

[0052] The connecting handle 720 is preferably a rod-shaped structure with elasticity, for example, an elastic rod formed by two rods twisting and winding each other as shown in the figure. Thus, a good power transmission effect can be achieved during the cleaning process, and it has a certain deformation ability to adapt to different usage conditions.

[0053] Optionally, the material of the bristles 730 includes a metal material, which has a better cleaning effect and a longer service life.

[0054] Combined Figure 6 , in some embodiments of the present disclosure, the hole punching auxiliary device further includes a conveying mechanism 300. The conveying mechanism 300 is located below the execution end (such as a drill bit or a laser, etc.) of the laser hole punching device. The conveying mechanism 300 is configured to adjust the positions of the pipe 100 to be processed and the auxiliary pipe 200 along the axial directions of the pipe 100 to be processed and the auxiliary pipe 200. By adjusting the positions of the pipe 100 to be processed and the auxiliary pipe 200 through the conveying mechanism 300, when performing the hole punching operation for a plurality of holes 101 to be punched, the alignment between the holes 101 to be punched and the laser hole punching device can be achieved, which is convenient for operation and is beneficial to improving the processing accuracy.

[0055] Optionally, the conveying mechanism 300 includes a support frame 310, a slide rail 320, a slider 330, and a driving assembly 340. The support frame 310 can be a support structure formed by components such as a rod or a plate. The support frame 310 is provided with a slide table 311, and the slide table 311 can be specifically arranged on the upper side of the support frame 310 and extends horizontally. The slide rail 320 is fixedly arranged on the upper side of the slide table 311, and the extending direction of the slide rail 320 is the same as the extending direction of the slide table 311. The slider 330 is slidably connected to the slide rail 320, and the slider 330 is configured to support the pipe 100 to be processed and the auxiliary pipe 200. When the slider 330 slides horizontally along the slide rail 320, it can drive the pipe 100 to be processed and the auxiliary pipe 200 located on the slider 330 to slide synchronously. The driving assembly 340 is located on the support frame 310 and is connected to the slider 330, and the driving direction of the driving assembly 340 is parallel to the extending direction of the slide rail 320.

[0056] The driving component 340 can be a cylinder, a hydraulic cylinder, a linear motor, a synchronous belt driving structure with a motor as the power source, a lead screw driving structure with a motor as the power source, etc. As long as it can realize the driving structure for reciprocating sliding of the slider 330 along the direction of the slide rail 320, it should be within the protection scope of this embodiment.

[0057] Optionally, the driving component 340 includes a servo motor, a lead screw and a nut. The servo motor is fixedly connected to the support frame 310. The lead screw is rotatably connected to the support frame 310 and connected to the motor shaft of the servo motor. The axial direction of the lead screw is parallel to the extension direction of the slide rail 320. The nut is in threaded cooperation with the lead screw and fixedly connected to the slider 330.

[0058] Optionally, a V-shaped groove is provided on the upper side of the slider 330. The extension direction of the V-shaped groove is parallel to the extension direction of the slide rail 320. The V-shaped groove can be used to limit the to-be-processed pipe 100 and the auxiliary pipe 200 to prevent the to-be-processed pipe 100 and the auxiliary pipe 200 from rolling.

[0059] Combined Figure 7 and Figure 8 , in some embodiments of the present disclosure, the hole punching auxiliary device further includes a first clamping component 400 and a second clamping component 500. The first clamping component 400 is arranged on the upper side of the slider 330. The first clamping component 400 is configured to clamp the to-be-processed pipe 100, form axial movement limitation and axial rotation limitation for the to-be-processed pipe 100, and keep the axis of the to-be-processed pipe 100 parallel to the extension direction of the slide rail 320. The second clamping component 500 is arranged on the upper side of the slider 330. The second clamping component 500 is configured to clamp the auxiliary pipe 200 and form axial movement limitation and axial rotation limitation for the auxiliary pipe 200.

[0060] Limiting the to-be-processed pipe 100 and the auxiliary pipe 200 respectively by using the first clamping component 400 and the second clamping component 500 can ensure the accuracy of the punching position, and there is no need to repeatedly calibrate the positions of the to-be-processed pipe 100 and the auxiliary pipe 200, effectively improving the processing efficiency.

[0061] Of course, in some embodiments, the first clamping component 400 and the second clamping component 500 can also be combined to form the same clamping component to simultaneously realize the clamping and limiting of the to-be-processed pipe 100 and the auxiliary pipe 200.

[0062] In some embodiments, the first clamping component 400 includes a first limiting clip 410 and a first elastic member 420.

[0063] There are two first limiting clips 410 symmetrically arranged. The two first limiting clips 410 are respectively slidably connected to the slider 330. The sliding directions of the two first limiting clips 410 are perpendicular to the extension direction of the slide rail 320. The two first limiting clips 410 are adapted to clamp on both sides of the workpiece pipe 100 to be processed. The sliding connection between the first limiting clip 410 and the slider 330 is realized, for example, by a sliding fit structure of a dovetail groove and a dovetail-shaped protrusion, etc., and no specific limitation is made here.

[0064] When the two first limiting clips 410 slide in the direction away from each other and the distance between the two first limiting clips 410 is increased, it is convenient to insert or remove the workpiece pipe 100 to be processed; when the two first limiting clips 410 slide in the direction close to each other and the distance between the two first limiting clips 410 is decreased, the clamping and fixing of the workpiece pipe 100 to be processed can be realized.

[0065] Optionally, the first limiting clip 410 includes a lateral limiting plate 411 and an end face limiting plate 412. The lateral limiting plate 411 is arranged vertically and is configured to abut against the side wall of the workpiece pipe 100 to be processed. The lateral limiting plate 411 can be a straight plate structure or an arc-shaped plate. Preferably, the lateral limiting plate 411 is an arc-shaped plate so that the lateral limiting plate 411 can better fit the workpiece pipe 100 to be processed. The end face limiting plate 412 is fixedly connected to the lateral limiting plate 411 and is configured to abut against the end of the workpiece pipe 100 to be processed. The end face limiting plate 412 is located at one end of the lateral limiting plate 411 facing the second clamping assembly 500 and on the side where the two first limiting clips 410 are close to each other. The end face limiting plate 412 is perpendicular to the lateral limiting plate 411.

[0066] When the two lateral limiting plates 411 of the two first limiting clips 410 are respectively in contact with the side wall of the workpiece pipe 100 to be processed, the two end face limiting plates 412 are in contact with the ends of the workpiece pipe 100 to be processed, and the auxiliary pipe 200 can pass through between the two end face limiting plates 412. Optionally, an arc-shaped surface is provided at one end where the two end face limiting plates 412 are close to each other, and the arc-shaped surface is in contact with the side wall of the auxiliary pipe 200.

[0067] There are two first elastic members 420 symmetrically arranged. The two first elastic members 420 are respectively connected to the two first limit clips 410. The two first elastic members 420 are configured to provide an elastic force to the two first limit clips 410 that makes the two first limit clips 410 tend to approach each other. The first elastic member 420 can be a tension spring, a compression spring, an elastic sheet, etc. For example, the first elastic member 420 is a compression spring. The two compression springs are respectively arranged on the sides where the two first limit clips 410 are away from each other. One end of the compression spring is fixed to the slider 330, and the other end faces the corresponding first limit clip 410 and abuts against the corresponding first limit clip 410. When the two first limit clips 410 move away from each other, the compression spring is compressed and deformed.

[0068] Under the action of the two first elastic members 420, the two first limit clips 410 can clamp and fix the workpiece tube 100 to be processed, thereby forming an axial movement limit and an axial rotation limit for the workpiece tube 100 to be processed, and keeping the axis of the workpiece tube 100 parallel to the extension direction of the slide rail 320.

[0069] For the convenience of clamping and positioning the workpiece tube 100, optionally, the two lateral limit plates 411 are respectively provided with inclined surfaces. The two inclined surfaces are inclined gradually in the direction away from each other from the end close to the end face limit plate 412 to the end far from the end face limit plate 412. When clamping and fixing the workpiece tube 100, the workpiece tube 100 can be inserted between the two inclined surfaces. The two first limit clips 410 automatically slide in the direction away from each other under the push of the workpiece tube 100.

[0070] In some embodiments, the second clamping assembly 500 includes an adjustment seat 510, a positioning bolt 520, a second limit clip 530, and a second elastic member 540.

[0071] The adjustment seat 510 is slidably connected to the slider 330. The sliding direction of the adjustment seat 510 is parallel to the extension direction of the slide rail 320. The adjustment seat 510 and the slider 330 are slidably connected, for example, by a sliding fit structure of a dovetail groove and a dovetail protrusion, etc., and no specific limitation is made here. The adjustment seat 510 is configured to abut against the end of the auxiliary tube 200, and adapt to different lengths of the tube part protruding by sliding the adjustment seat 510.

[0072] The adjustment seat 510 is provided with an air flow hole. The aperture of the air flow hole is equal to or slightly larger than the inner hole aperture of the auxiliary tube 200. In the state where the adjustment seat 510 abuts against the auxiliary tube 200, the air flow hole is communicated with the inner hole of the auxiliary tube 200, which can ensure that the air flow provided by the purging mechanism 600 smoothly passes through the auxiliary tube 200.

[0073] The positioning bolt 520 is vertically arranged and is threadedly connected to the adjusting seat 510 through the threaded hole provided in the adjusting seat 510. Moreover, the lower end of the positioning bolt 520 abuts against the slider 330.
