Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a full-protection laser tube cutting machine. Background Art

[0002] The chuck-type laser tube cutting machine has the characteristics of high precision and high efficiency. It is especially suitable for cutting large tubes. It is generally composed of a base frame, multiple chucks, and a laser cutting assembly. The multiple chucks are used to clamp the tubes and push the tubes in the direction of the laser cutting assembly. In addition, in order to improve the support effect for large tubes, a centering follower mechanism is generally set to support the tubes to ensure that the tubes do not shake during rotation. As we all know, the more automated the laser tube cutting machine is, the more transmission structures it involves. The exposed transmission structure is easy to cause harm to the operator, and the high-intensity laser beam emitted by the laser cutting assembly may also cause harm to the operator. Although some existing laser tube cutting machines are equipped with some basic protective measures, the protection range is limited and cannot completely cover areas where accidental touch may occur.

DETAILED DESCRIPTION

[0031] The present invention provides a fully protected laser tube cutting machine. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0032] See also Figure 1 and Figure 2 The present invention provides a full-protection laser tube cutting machine, comprising a side-mounted bed 1, a gantry 16 arranged on the side-mounted bed 1, a laser cutting assembly 2 arranged on the gantry 16, and a first chuck structure 41, a second chuck structure 42 and a third chuck structure 43 which are sequentially slidably arranged along the Y-axis direction of the side-mounted bed 1; a plurality of mounting side seats 13 are arranged on the left side of the side-mounted bed 1, and a centering follower mechanism 3 is arranged on the mounting side seat 13, and the centering follower mechanism 3 is used to clamp the pipe material to center the pipe material, and the outer portion of the centering follower mechanism 3 is arranged There is a centering follower mechanism protection structure 5; a plurality of reinforced side seats 14 are arranged on the right side of the side-hanging bed 1, and a material unloading mechanism is arranged between the reinforced side seats 14, and the material unloading mechanism is used to unload the pipe after cutting; a support seat 15 is arranged between the adjacent mounting side seats 13 and the reinforced side seats 14, and the front side of the gantry 16 is fixedly connected to the support seat 15; the outside of the support seat 15 and the gantry 16 is surrounded by a protective box 6, and the protective box 6 is used to enclose the laser cutting assembly 2 inside it; please refer to Figure 4 and Figure 5 The front of the protection box 6 is provided with a material unloading area 611 for unloading pipes, and the left and right sides of the protection box 6 are respectively provided with avoidance areas 612 for the second chuck structure 42 and the third chuck structure 43 to pass through; please refer to Figure 1 A first chuck protection structure 44 is disposed outside the first chuck structure 41 , a second chuck protection structure is disposed outside the second chuck structure 42 , and a third chuck protection structure 46 is disposed outside the third chuck structure 43 .

[0033] The pipe to be cut is loaded onto the centering follower mechanism 3, and then the centering follower mechanism 3 centers the pipe and lifts the pipe to be coaxial with the first chuck structure 41, the second chuck structure 42 and the third chuck structure 43. The pipe will be clamped by the first chuck structure 41 and the second chuck structure 42 and pushed toward the laser cutting assembly 2 by the first chuck structure 41 to achieve cutting feeding. Therefore, the avoidance area 612 is opened on the left and right sides of the protective box 6 to avoid the corresponding chuck structure, and the cut pipe section will be clamped by the third chuck structure 43 and unloaded with the cooperation of the unloading mechanism. Furthermore, since the second chuck structure 42 can move relative to the laser cutting assembly 2, when there is residual material left in the pipe, the laser cutting head of the laser cutting assembly 2 is vertically downward, the distance between the second chuck structure 42 and the laser cutting assembly 2 is reduced, and the remaining pipe is directly cut, thereby reducing the amount of residual material, and the residual material / short material is discharged from the discharge area 611, and the discharge area 611 can be placed in a discharge box for receiving materials. At the same time, the discharge area 611 is also convenient for operators to enter the interior of the protective box 6 from here during the non-operating time of the laser pipe cutting machine.

[0034] The above-mentioned laser tube cutting machine, by setting up a centering follower mechanism protection structure 5, multiple chuck protection structures, and a protection box 6, encloses the centering follower mechanism 3, the corresponding chuck drive mechanism, the gantry 16 and the laser cutting assembly 2 inside the corresponding structure. When the operator is located outside the protection structures and the protection box 6, it can effectively prevent the drive mechanisms from touching the operator, and can effectively prevent the scattering and reflection of the laser during the cutting process, thereby preventing the laser from escaping and causing harm to the operator.

[0035] Specifically, the laser cutting component 2 enables the laser cutting head to reciprocate along the X-axis and Z-axis directions through various driving mechanisms. The laser cutting component 2 cooperates with three chuck structures that can be pushed along the Y-axis direction to achieve multi-directional cutting of the pipe. The laser cutting component 2 and the laser cutting head are both existing technologies and will not be described here.

[0036] More specifically, the centering follower mechanism protection structure 5, the protection box 6, etc. are all made of sheet metal parts, and related components such as air source processing can be centrally installed thereon for easy adjustment.

[0037] See also Figure 3-Figure 5In some embodiments, a front protective curtain 68 is provided in front of the protective box 6, and the front protective curtain 68 is used to shield the unloading area 611; side protective curtains 69 are provided on the left and right sides of the protective box 6, respectively, and the side protective curtains 69 are used to shield the avoidance area 612. The protective box 6 cooperates with the front protective curtain 68 and the side protective curtains 69 to achieve all-round laser protection. Moreover, the front protective curtain 68 has a lower manufacturing cost than the protective door, and it is more convenient to enter and exit the protective box 6. Specifically, the front protective curtain 68 and the side protective curtain 69 are preferably black fireproof curtains. Black has a strong shielding ability for the light generated by the laser, and the fireproof curtains are made of fireproof materials, which can prevent the fireproof curtains from melting due to heat, thereby extending the service life of the fireproof curtains.

[0038] See also Figure 4 and Figure 6 In some embodiments, the lower surface of the protective box 6 is provided with a first clip 63 and a second clip 64, and the upper part of the front protective curtain 68 and the upper part of the side protective curtain 69 are clamped between the first clip 63 and the second clip 64 by fasteners. In actual application, the first clip 63, the second clip 64 and the front protective curtain 68 or the side protective curtain 69 are modularly designed. When assembling, the modular whole can be installed to the corresponding position of the protective box 6. When the front protective curtain 68 and the side protective curtain 69 need to be replaced, the corresponding locking parts can be removed and the new front protective curtain 68 and the side protective curtain 69 can be replaced, which is convenient for disassembly and assembly. In addition, the first clip 63 and the second clip 64 cooperate with the fasteners to clamp and fix the upper part of the front protective curtain 68 and the side protective curtain 69. This connection method can ensure that the front protective curtain 68 and the side protective curtain 69 are stably attached to the protective box 6 during use.

[0039] See also Figure 6 , see Figure 3 In some embodiments, the fasteners are screws / bolts / screws and nuts (not shown in the figure), and the first clamping piece 63 and the second clamping piece 64 are provided with a plurality of through holes 631 extending along the length direction thereof, and the fasteners are located in the corresponding through holes 631. The front protective curtain 68 and the side protective curtain 69 are both made of soft materials, so the screws / bolts / screws can be passed through the corresponding through holes 631 and through both sides of the front protective curtain 68 and the side protective curtain 69, and finally clamped in the gap between the first clamping piece 63 and the second clamping piece 64 by nuts to complete the assembly, and then the modular overall structure is installed at the corresponding position of the protective box 6.

[0040] See also Figure 3 and Figure 4In some embodiments, a viewing window 613 is provided in front of the protective box 6, and a transparent window 614 is provided in the viewing window 613. During the laser cutting operation, the operator needs to observe the situation in the cutting area in real time in order to timely understand the cutting progress, the pipe cutting status, and whether there are any abnormalities. The setting of the transparent window 614 enables the operator to clearly see the working conditions of the laser cutting assembly 2 in the protective box 6 through the viewing window 613 while ensuring his own safety, ensuring the smooth progress of the cutting work, while avoiding the risk of injury caused by direct exposure to laser radiation. Specifically, the transparent window 614 is preferably radiation-proof glass.

[0041] See also Figure 4 In some embodiments, the protective box 6 includes a lower box 61 and an upper box 62 connected to the lower box 61. The length of the upper box 62 along the Y-axis direction is less than the length of the lower box 61 along the Y-axis direction. The upper box 62 is used to accommodate the driving mechanism of the laser cutting assembly 2. The cutting area covers a wide range, so the volume of the lower box 61 needs to be designed to be larger, while the active area of ​​the laser cutting assembly 2 and the Z-axis drag chain installed on the gantry 16 is relatively small, so the volume of the upper box 62 is designed to be smaller. The above arrangement can avoid waste of space and make the spatial layout and volume of the protective box 6 more reasonable.

[0042] See also Figure 3-Figure 5 In some embodiments, a baffle 65 is further provided between the side-mounted bed 1 and the gantry 16. The baffle 65 is located in the avoidance area 612, and the lower surface of the baffle 65 is fixedly connected to the upper surface of the support seat 15. In practical applications, the lower surface of the front part of the gantry 16 is fixedly connected to the support seat 15, and the lower surface of the rear part is fixedly connected to the side-mounted bed 1. Since there is a certain distance between the support seat 15 and the laser cutting assembly 2, a baffle 65 is provided. The baffle 65 cooperates with the protective box 6 to further reduce the escape of the laser in the cutting area. In order to further enhance the shielding effect of the baffle 65 on the laser, an arc groove matching the curvature of the lower part of the chuck is also provided on the upper part of the baffle 65.

[0043] See also Figure 4 and Figure 5In some embodiments, the support base 15 is a hollow structure, and an exhaust pipe 66 is provided between the support base 15 and the side-mounted bed 1. The exhaust pipe 66 passes through the left and right sides of the support base 15 and the front and rear sides of the side-mounted bed 1; the air inlet of the exhaust pipe 66 is connected to the inner cavity of the protective box 6. The exhaust pipe 66 is connected to the exhaust device. The above arrangement can quickly absorb the dust generated in the cutting area to protect the working environment. In addition, the exhaust pipe 66 is short in length, which makes full use of the position of the side-mounted bed 1 and the support base 15, and the design is more reasonable.

[0044] See also Figure 4 In some embodiments, a shield 67 is provided on the side wall of the support base 15 facing the cutting area; the shield 67 is used to cover the air inlet of the exhaust pipe 66 inside the shield; and an exhaust hole 671 is also provided on the shield 67. The shield 67 covers the air inlet of the exhaust pipe 66, and can effectively guide the smoke and exhaust gas generated during the laser cutting process to flow toward the exhaust hole 671. In addition, the cutting area also involves the unloading area 611, so the setting of the shield 67 can also prevent the short tube / tail material from directly contacting the exhaust pipe 66 after falling and damaging the exhaust pipe 66.

[0045] See also Figure 4 In some embodiments, the side wall of the shield 67 is configured as an inclined surface; the inclined surface faces upward, and the air extraction hole 671 is disposed on the inclined surface. The configuration of the inclined surface can provide guidance for the tailings falling onto the shield 67, so as to prevent the tailings from falling onto the shield 67 and blocking the air extraction holes 671 on the shield 67, thereby affecting the air extraction effect.

[0046] See also Figure 2 and Figure 8 In some embodiments, a distance measuring mechanism 411 is disposed outside the first chuck structure 41, and the distance measuring mechanism 411 is used to measure the distance from the left end of the tube on the centering follower mechanism 3 to the feeding material; please refer to Figure 7 and Figure 8The first chuck protection structure 44 includes a first protective cover 441 for enclosing the first Y-axis side hanging plate 81, the first Y-axis side hanging plate driving mechanism 82, the first chuck driving mechanism and the distance measuring mechanism 411 therein; the first protective cover 441 is provided with an escape hole 442 on the side wall facing the laser cutting assembly 2 for evading the distance measuring mechanism 411. In this embodiment, the first Y-axis side hanging plate driving mechanism 82 can be driven by a motor, a gear and a rack, and the first chuck structure 41 is fixedly connected to the first Y-axis side hanging plate 81, so that the first Y-axis side hanging plate 81 can drive the first chuck structure 41 to move back and forth along the length direction of the side hanging bed 1. In actual application, the pipe loaded onto the centering follower mechanism 3 needs to be driven by the first Y-axis side hanging plate driving mechanism 82 to move the first chuck structure 41 toward the left end of the pipe. According to the program setting, after the first chuck structure 41 moves to the set position, it uses the distance measuring mechanism 411 to extend to the right and touch the left end of the pipe to measure the distance from the first chuck structure 41 to the left end of the pipe, so that the first chuck structure 41 can be firmly clamped to the left end of the pipe to avoid the occurrence of empty clamping of the pipe. Specifically, the distance measuring mechanism 411 is a cylinder, a movable plate, and a stroke sensor. The movable plate is extended from the avoidance hole 442 by extending the output end of the cylinder, and the moving stroke of the movable plate is measured by the stroke sensor. The above-mentioned first chuck protection structure 44 can enclose the first Y-axis side hanging plate driving mechanism 82 and the first chuck driving mechanism inside it to avoid exposure of the driving mechanism.

[0047] In some embodiments, the side walls of the gantry 16 in the front and rear directions are respectively provided with a through-beam sensor (not shown in the figure); the through-beam sensor is used to cooperate with the distance measuring mechanism 411 to sense the position of the right end of the pipe loaded on the centering follower mechanism 3 and measure the length of the pipe to be cut. The pipe clamped by the first chuck structure 41 is pushed to the right until the right end of the pipe blocks the two through-beam sensors, and the actual length of the pipe can be calculated by signal conversion, thereby achieving precise cutting.

[0048] See also Fig. 9 and Fig.10In some embodiments, the second chuck protection structure and the third chuck protection structure 46 both include a first protective cover 461 surrounding the second Y-axis side hanging plate, the second Y-axis side hanging plate driving mechanism / the third Y-axis side hanging plate 83, and the third Y-axis side hanging plate driving mechanism 84, a second protective cover 463 surrounding the second chuck driving mechanism / the third chuck driving mechanism, and a fixed cover 462 whose two ends are respectively connected to the side walls of the first protective cover 461 and the second protective cover 463; the fixed cover 462 is used to be fixedly connected to the outer side wall of the second chuck structure 42 / the third chuck structure 43. In practical applications, the first protective cover 461 is used to cover the second Y-axis side hanging plate and the driving mechanism thereon, the third Y-axis side hanging plate 83 and the driving mechanism thereon, and the second protective cover 4633 is used to cover the driving mechanism on the second chuck / the third chuck, which can effectively prevent the operator from contacting the driving mechanism, reduce the probability of safety accidents, and ensure the personal safety of the operator. In addition, it can prevent foreign matter from entering the driving mechanism and interfering with the operation of the driving mechanism; it can also make the appearance of the laser tube cutting machine more neat and beautiful. The fixed cover 462 is used to connect the first protective cover 461 and the second protective cover 463, so that the chuck protection structure forms a whole, which is convenient for installing the entire chuck protection structure on the laser tube cutting machine, or removing the entire chuck protection structure from the laser tube cutting machine.

[0049] Specifically, the second Y-axis side hanging plate driving mechanism and the third Y-axis side hanging plate driving mechanism 84 can be driven by a motor, a gear and a rack, and the driving mechanism is a prior art.

[0050] For more details, please refer to Figure 4 The second chuck structure 42 is provided with a group of four large rollers 431 arranged in the up-down and left-right directions, and a group of four small rollers 432 arranged in the up-down and left-right directions. Fig. 9 The third chuck structure 43 is provided with a group of four large rollers 431 arranged in the up-down, left-right and right directions, a group of two small rollers 432 arranged in the left-right direction, and a group of two clamps 433 arranged in the up-down direction. The chuck structure in which the clamps 433 and the rollers cooperate is adopted, so that the third chuck structure 43 can be moved to the left side of the laser cutting assembly 2, that is, the three chuck structures clamp the pipe at the same time. In addition, the multiple groups of roller groups are provided, so that the positions of the second chuck structure 42 and the third chuck structure 43 can remain unchanged, and the first chuck structure 41 can be used to push the pipe, and the sliding force provided by the roller group is used to provide avoidance for the advancement of the pipe. The cooperation of multiple groups of large rollers 431 and small rollers 432, as well as the clamps 433, enables the clamping method of the chuck structure to have a variety of combinations, which can be adapted to pipe cutting in more application scenarios.

[0051] In some embodiments, a chuck protection plate is disposed in the inner cavity in the middle of the second chuck structure 42 and the third chuck structure 43. The chuck protection plate is used to protect the inner cavity of the chuck structure.

[0052] See also Fig. 9 In some embodiments, the first protective cover 461 includes a first cover body 4611 and a first inspection plate 4612 detachably connected to the first cover body 4611 by bolts / screws / screws; the first cover body 4611 is provided with a first inspection opening that matches the shape of the first inspection plate 4612, and the first inspection plate 4612 is used to cover the first inspection opening. The first protective cover 461 is made of sheet metal, and the first inspection opening is formed on the first protective cover 461, so that the driving mechanism inside the first protective cover 461 can be inspected through the first inspection opening after the first inspection plate 4612 is removed.

[0053] See also Fig. 9 In some embodiments, the second protective cover 463 includes a second cover body 4631 and a second inspection plate 4633 detachably connected to the second cover body 4631 by bolts / screws / screws; the second cover body 4631 is provided with a second inspection opening that matches the shape of the second inspection plate 4633, and the second inspection plate 4633 is used to cover the second inspection opening. Similarly, the second protective cover 463 is made of sheet metal, and by forming the second inspection opening on the second protective cover 463, it is convenient to inspect the driving mechanism inside the second protective cover 463 through the second inspection opening after the second inspection plate 4633 is removed.

[0054] See also Fig. 9 In some embodiments, the side wall and the bottom of the second cover body 4631 are provided with heat dissipation holes 4632. During the operation of the device, the chuck drive mechanism generates heat. If the heat cannot be dissipated in time, the temperature inside the mechanism will rise. The heat dissipation holes 4632 provided on the side wall and the bottom can form a good heat dissipation channel, allowing the heat to be dissipated to the external environment in time, so that the chuck drive mechanism can continue to operate stably within a suitable temperature range. In this embodiment, the bottom of the first cover body 4611 is an open structure, so there is no need to set additional heat dissipation holes.

[0055] See also Fig. 9In some embodiments, the fixed cover 462 includes a first extension section 4621 fixedly connected to the side wall of the first protective cover 461, a second extension section 4623 fixedly connected to the side wall of the second protective cover 463, and an arc section 4622 for connecting the first extension section 4621 and the second extension section 4623; the arc section 4622 has an arc that is consistent with the arc of the second chuck structure 42 / third chuck structure 43, the lower surface of the arc section 4622 abuts against the outer peripheral wall of the upper part of the second chuck structure 42 / third chuck structure 43, and the arc section 4622 is fixedly connected to the second chuck structure 42 / third chuck structure 43. The above-mentioned fixed cover 462 is adapted to the shape of the second chuck structure 42 / third chuck structure 43. In practical applications, the first extension section 4621, the second extension section 4623 of different lengths or the arc section 4622 of different arcs can be designed to make the chuck protection structure adapt to chuck structures with different arc specifications. In addition, each part of the three-section fixed cover 462 is connected to other parts of the equipment, thereby ensuring that the chuck protection structure is firmly installed and easy to assemble, and the three parts of the fixed cover 462 can be fixed to the equipment in a distributed manner.

[0056] See also Figure 7 and Fig. 9 In some embodiments, the first chuck protection structure 44, the second chuck protection structure and the third chuck protection structure 46 are all provided with a Y-axis drag chain fixing seat 464 connected to the first chuck protection structure 44 / the second chuck protection structure / the third chuck protection structure 46 on the outside, and the Y-axis drag chain fixing seat 464 is used to be fixedly connected to the end of the Y-axis drag chain. The Y-axis drag chain is used to accommodate and protect various cables, air pipes and other pipelines so that they can follow and move in an orderly manner during the movement of the equipment. The setting of the Y-axis drag chain fixing seat 464 provides a special fixed position for the Y-axis drag chain, ensuring that the Y-axis drag chain can be accurately located on the predetermined path when the equipment is running, avoiding the Y-axis drag chain from swinging randomly or interfering with other components, and making the wiring inside the equipment more standardized and neat. In addition, the Y-axis drag chain fixing seat 464 provides a clear position and connection method for the installation of the Y-axis drag chain. The operator only needs to fix the end of the Y-axis drag chain on the Y-axis drag chain fixing seat 464 to complete the installation. The operation is simple and convenient; it is also conducive to regular maintenance and replacement.

[0057] See also Figure 5In some embodiments, the centering follower mechanism protection structure 5 includes a first protective plate 51 for being fixedly connected to the corresponding mounting side seat 13, and a second protective plate 53 for being fixedly connected to the front side wall of the side-mounted bed 1; a lap plate 52 is provided on the side wall of the first protective plate 51 facing the second protective plate 53, and the lap plate 52 and the inner side wall of the second protective plate 53 are abutted and fixed by bolts; the first protective plate 51, the second protective plate 53, the mounting side seat 13, and the side-mounted bed 1 form a space for installing the centering follower mechanism 3.

[0058] In actual application, the centering follower mechanism 3 is located at the front side of the side-mounted bed 1, that is, the front is the operating side. By enclosing the centering follower mechanism 3 in the space surrounded by the first protective plate 51, the second protective plate 53, the mounting side seat 13 and the side-mounted bed 1, it can effectively prevent the operator from accidentally contacting the centering follower mechanism 3, and avoid the risk of injury caused by the operator accidentally touching the running or stationary centering follower mechanism 3, such as mechanical injuries such as pinching and abrasion, thereby ensuring the personal safety of the operator. In addition, when installing the first protective plate 51 and the second protective plate 53, or when the centering follower mechanism 3 needs to be maintained or repaired, the protective structure can be relatively conveniently disassembled and installed through the connection method of the lap plate 52 and the bolts, which improves the disassembly and assembly speed and reduces the difficulty and time cost of maintenance work.

[0059] Furthermore, the structure is open at the top and bottom, which makes it easy to observe the operation of the centering follower mechanism 3 from the outside and is beneficial to heat dissipation.

[0060] See also Figure 1 and Figure 2 , Fig.11 and Fig.12In some embodiments, the side-hanging bed 1 is provided with a plurality of first wiring openings 11, a second wiring opening 12 and a third wiring opening 1811 arranged along its length direction; the plurality of first wiring openings 11 correspond to the centering follower mechanism 3, and are used to collect the corresponding lines of the centering follower mechanism 3 to the rear side of the side-hanging bed 1; the plurality of second wiring openings 12 correspond to the unloading mechanism, and are used to collect the corresponding lines of the unloading mechanism to the rear side of the side-hanging bed 1; the number of the third wiring openings 1811 is set to three, and the lines of the first chuck structure 41, the second chuck structure 42 and the third chuck structure 43 are collected to the rear side of the side-hanging bed 1 through the Y-axis drag chain respectively. In actual application, after the centering follower mechanism 3 is uniformly installed on the right side wall of the corresponding mounting side seat 13, the cables of the centering follower mechanism 3 can be guided to the rear of the side-mounted bed 1 through the nearest first wiring opening 11 on the side-mounted bed 1; similarly, after assembling the unloading mechanism, the cables of the unloading mechanism are guided to the rear of the side-mounted bed 1 through the nearest second wiring opening 12; the cables of the first chuck structure 41, the second chuck structure 42, and the third chuck structure 43 are guided to the corresponding third wiring opening 1811 via the corresponding Y-axis drag chain, and then gathered to the rear of the side-mounted bed 1.

[0061] See also Figure 1 In some embodiments, an electric control cabinet 7 is further provided behind the protection box 6; the electric control cabinet 7 is used to centrally manage the lines gathered to the rear side of the side-mounted bed 1 and the lines inside the protection box 6.

[0062] See also Fig.11 and Fig.12 In some embodiments, the side-mounted bed 1 includes a transverse tube group 17 formed by stacking and fixing a plurality of transverse tubes, and a reinforcing frame 18 disposed behind the transverse tube group 17. The transverse tube group 17 is formed by stacking a plurality of transverse tubes, and transverse tubes of different heights can be selected for stacking according to the height of the side-mounted bed 1. The preparation process is simple and can be completed without cutting large-format plates, which is conducive to reducing manufacturing costs. The setting of the reinforcing frame 18 is used to improve the structural rigidity of the side-mounted bed 1 on the one hand, and to provide a routing space for the direction of the cables on the other hand, so as to make full and reasonable use of the spatial layout of the chassis.

[0063] See also Fig.12In some embodiments, the reinforcement frame 18 includes a reinforcement upper cross beam 181, a reinforcement lower cross beam 182 disposed below the reinforcement upper cross beam 181, and a plurality of connecting vertical beams 183 for connecting the reinforcement upper cross beam 181 and the reinforcement lower cross beam 182; the bottom of the connecting vertical beam 183 is provided with a wiring notch 184 at a position close to the transverse tube group 17; the reinforcement upper cross beam 181, the reinforcement lower cross beam 182 and the connecting vertical beam 183 form a wiring cavity; the first wiring opening 11 and the second wiring opening 12 are disposed on the transverse tube group 17, and the third wiring opening 1811 is disposed on the reinforcement upper cross beam 181. The reinforcement upper cross beam 181 and the reinforcement lower cross beam 182 together with the connecting vertical beam 183 form a more stable frame structure, which significantly enhances the rigidity and anti-deformation ability of the entire side-mounted bed 1. By limiting the setting positions of the first wiring opening 11, the second wiring opening 12 and the third wiring opening 1811, it is adapted to the centering follower mechanism 3, the unloading mechanism, and the positions of the three chuck structures relative to the side-mounted bed 1, and the wiring notch 184 is designed to cooperate with the first wiring opening 11, the second wiring opening 12 and the third wiring opening 1811, so that the cables collected in the wiring cavity are uniformly processed through the wiring notch 184. The above setting provides a more convenient wiring channel, standardizes the line direction, is both beautiful and improves safety, and also simplifies the maintenance and inspection process. In addition, the rear side of the reinforcement frame 18 is also fixed with a sheet metal part. The wiring cavity surrounded by the sheet metal part and the reinforcement frame 18 can prevent the lines collected in the wiring cavity from being exposed, thereby improving the overall aesthetics of the equipment.
