Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting and welding, and particularly to a self-resetting multi-directional anti-collision protection device. Technical Background

[0002] With the development of technology and productivity, lasers have been widely used in industrial processing and other fields. In the processing industry, laser cutting technology has become one of the core processes of modern manufacturing due to its advantages of high precision and high efficiency. However, during laser cutting in complex working conditions, accidental collisions between the laser head and materials or tooling fixtures frequently occur, which may cause equipment damage, processing interruption, and even safety hazards.

[0003] In the current existing technologies, efforts are made to avoid the occurrence of collision accidents during the operation of the laser head. Due to the complex working environment, diverse working types, and manual operations of laser equipment, the occurrence of collision accidents is difficult to avoid. Moreover, the laser head, as the core component of the laser equipment, is extremely vulnerable to damage or even destruction in collision accidents. The cost of repairing or replacing the laser head is high. And if the laser machine tool supplier is far away from the equipment user, one can only wait for the engineer to come to repair and replace the parts, which greatly affects the accuracy of the laser machine tool and the normal production of the factory.

[0004] However, for the existing anti-collision protection technologies in the current industry, there is no device or apparatus that can protect the laser equipment during a collision accident. Based on this situation, the present invention proposes a self-resetting multi-directional anti-collision protection device for protecting the laser head during a collision accident that occurs during the operation of the laser equipment. Summary of the Invention

[0005] The purpose of the present invention is to fill the gap in the existing technology, that is, the protection technology during a collision accident, and thus propose a self-resetting multi-directional anti-collision protection device.

[0006] In order to protect the laser equipment during a collision accident, the present invention uses the following technical solutions:

[0007] The self-resetting multi-directional anti-collision protection device includes:

[0008] Inside the installation main body, there is a reset support seat. A plurality of corresponding uniformly distributed truncated cones are arranged between them to limit the installation of buffer springs. The outer cylindrical surface and the inner hole of the reset support seat are respectively grooved to install a first sealing ring and a second sealing ring. A copper triangular pressing block is installed on the front end face of the reset support seat. The copper triangular pressing block supports and jacks up the swing arm rocker. The rear large cylinder of the swing arm rocker is provided with three groups of flange platforms and a positioning module is installed. The spherical surface of the positioning module is in contact and cooperation with the V-shaped notch at the rear end of the limit sleeve. The limit sleeve is installed in the installation ring groove on the inner end face of the front end cover. The front end cover is provided with threaded holes and a end cover bushing is installed; The front round rod of the swing arm rocker extends out from the inner hole of the end cover bushing and installs a front mounting plate. The front end of the front round rod of the swing arm rocker is provided with a dust screen installation groove and a metal dust screen is installed. A dust screen cover plate is installed on the front end cover at the rear end of the metal dust screen;

[0009] A cylinder flush with the front end face is arranged at the center of the installation main body. There are threaded holes inside the cylinder, and a displacement detection switch assembly and a first switch trigger are installed; The first switch trigger is provided with an inner hole and a long slot for installing and limiting the second switch trigger; There is a hole for installing and fixing the trigger spring inside the second switch trigger; A counterbore is arranged at the bottom of the installation main body to install a fixing nut for fixing the displacement detection switch assembly, and a rear mounting plate is installed on the bottom end face; The outer cylindrical surface of the installation main body is provided with a cut surface and a circuit board mounting seat is installed; An induction circuit board is installed inside the circuit board mounting seat, and there are mounting holes on its side and a signal connector is installed; Mounting holes are arranged on the outer wall at the rear end of the installation main body, and an air pipe joint and a pressure relief valve are installed.

[0010] As a preferred embodiment of the present invention: There are three sections of uniformly distributed special-shaped cylindrical surfaces on the front end face of the reset support seat. There are guide grooves on the surface, and limit bolt mounting holes corresponding to the guide grooves of the reset support seat are arranged on the outer cylindrical surface of the main body.

[0011] As a preferred embodiment of the present invention: The triangular direction position of the copper triangular pressing block is the same as the direction position of the three groups of flange platforms on the rear large cylinder of the swing arm rocker.

[0012] As a preferred embodiment of the present invention: There are three groups of pressure relief grooves on the inner wall of the installation main body.

[0013] As a preferred embodiment of the present invention: The special-shaped cylindrical surface on the reset support seat is larger than the outer circle at the rear end of the limit sleeve, and the special-shaped cylindrical surface on the reset support seat and the V-shaped notch at the rear end of the limit sleeve are staggered in position to prevent interference with the positioning module.

[0014] As a preferred embodiment of the present invention: The mating surface between the V-shaped notch at the rear end of the limit sleeve and the spherical surface of the position ball block is provided with an inclined surface with an inward draft angle.

[0015] As a preferred embodiment of the present invention: The bottom end face of the end cover bushing and the end face of the front cover mounting ring groove are slightly higher than the lowest point of the V-shaped notch on the limit sleeve, so that it is in spherical contact with the positioning module for limit.

[0016] As a preferred embodiment of the present invention: The outer cylindrical surface at the bottom of the swing arm rocker is provided with an inclined surface that allows it to swing in any direction.

[0017] As a preferred embodiment of the present invention: The clearance between the front round rod of the swing arm rocker and the inner hole of the end cover bushing, and the clearance between the rear end face of the front mounting plate installed on the front end face of the front round rod of the swing arm rocker and the end face of the dust-proof net cover are greater than the distance when the swing arm rocker swings to the limit position.

[0018] As a preferred embodiment of the present invention: The spherical surface of the positioning module installed on the swing arm rocker slides along the V-shaped notch at the rear end of the limit sleeve (8) during impact, and is pushed back to the origin by air pressure and spring after the impact factor is eliminated to achieve automatic reset.

[0019] The beneficial effects of the present invention are as follows:

[0020] It can protect against impacts from various directions: The self-resetting multi-directional anti-collision protection device can handle impacts from all directions (such as left and right, front and back, up and down). By rotating, swinging or displacing the swing arm rocker, the air inside the 1-body and the 23-buffer spring are compressed to buffer the impact force, thereby reducing damage to the laser head and related mechanical components.

[0021] Automatic reset function: Through the contact and cooperation design between the 10-positioning module installed on the 9-swing arm rocker and the groove surface of the 8-limit sleeve, under the action of air pressure and spring, after the impact factor is eliminated, the 10-positioning module installed on the 9-swing arm rocker can slide along the V-shaped notch at the rear end of the 8-limit sleeve back to the origin for automatic reset, and the V-shaped notch at the rear end of the 8-limit sleeve is provided with an inclined surface with an inward draft to ensure the reset accuracy of the 9-swing arm rocker and the 10-positioning module, ensuring that the laser head can quickly return to the normal working state.

[0022] Impact alarm mechanism: The rapid collision detection time closes 2 wires, applicable to both DC and AC. When an impact occurs, the displacement detection switch will be triggered, sending a signal to the machine tool control system to immediately stop the machine and raise the laser head to avoid further damage.

[0023] Dust-proof design: The design of the dust-proof net and the dust-proof cover can prevent dust and smoke from entering the equipment interior, reduce pollution, delay equipment aging and reduce the maintenance frequency.

[0024] Strong adaptability: The front and rear mounting plates of the installation part can be adjusted according to the hole positions of different laser heads and machine tools to achieve the maximum degree of adaptability.

[0025] In summary, the present invention exhibits significant advantages in terms of anti-collision ability, high-precision self-resetting, structural design, and maintenance convenience, filling the gap in the protection device for laser equipment during collision accidents in the industry.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0040] The self-resetting multi-directional anti-collision protection device, as Figures 1 to 8 shown, includes: a mutually cooperating 1 - mounting main body and 2 - reset support base. Corresponding uniformly distributed convex platforms are provided on the inner bottom surface of the 1 - mounting main body and the lower end surface of the 2 - reset support base, and the 22 - buffer springs are mounted and limited on the convex platforms; grooves are provided on the inner hole and the outer cylindrical surface of the 2 - reset support base, and the 3 - first sealing ring and the 4 - second sealing ring are respectively mounted, so as to form a sealed space inside the 1 - mounting main body; three uniformly distributed special-shaped cylindrical surfaces are provided on the other end surface of the 2 - reset support base, guiding grooves are opened on the surfaces, and holes for mounting and limiting screws in cooperation therewith are provided on the outer cylindrical surface of the 1 - mounting main body to prevent the 2 - reset support base from rotating; the 5 - copper triangular pressing block is mounted on the front circular surface of the 2 - reset support base, and the 5 - copper triangular pressing block jacks up the 9 - swing arm rocker;

[0041] The interior of the 9 - swing arm rocker is hollow. The 5 - copper triangular pressing block contacts its first - stage step surface, and the depth of the first - stage step hole is less than the height of the 5 - copper triangular pressing block, that is, there is a gap between the rear end face of the 9 - swing arm rocker and the 2 - reset support seat. And the rear end face of the 9 - swing arm rocker is provided with an inclined surface, enabling it to swing in any direction. The rear - end large cylinder of the 9 - swing arm rocker is provided with three groups of flange platforms, and three 10 - positioning modules are installed on the platforms. The spherical surfaces of the 10 - positioning modules are matched with the V - shaped notch at the rear end of the 8 - limiting sleeve for positioning. And the 10 - positioning modules installed on the 9 - swing arm rocker can slide along the V - shaped notch at the rear end of the 8 - limiting sleeve under the action of impact force, air pressure and spring force to relieve the damage during impact or for automatic reset. The 8 - limiting sleeve is installed in the annular groove of the 6 - front end cover, and the installation direction is unique. And the 6 - front end cover is provided with a large threaded hole for installing the 7 - end - cover bushing, and the front - end face of the large cylinder of the 9 - swing arm rocker is matched with the rear - end face of the 7 - end - cover bushing. By adjusting the threaded installation depth of the 7 - end - cover bushing, the front - and - back movement of the 9 - swing arm rocker is adjusted to ensure the cooperation between the 10 - positioning module and the V - shaped notch at the rear end of the 8 - limiting sleeve. The bottom - end face of the 7 - end - cover bushing is slightly higher than the lowest point of the V - shaped notch on the 8 - limiting sleeve, making it contact and limit the spherical surface of the 10 - positioning module. And the end - face of the annular groove of the 6 - front end cover is slightly higher than the lowest point of the V - shaped notch on the 8 - limiting sleeve, making it contact and limit the spherical surface of the 10 - positioning module. The front - end round rod of the 9 - swing arm rocker extends out from the inner hole of the 7 - end - cover bushing. And the front - end face is provided with a threaded hole and installs the 25 - front mounting plate. The front - end of the front - end round rod of the 9 - swing arm rocker is provided with a dust - proof net mounting groove and installs the 20 - metal dust - proof net, which fits with the front - end face of the 6 - end cover. The 11 - dust - proof cover plate is installed on the 6 - end cover to prevent the 20 - dust - proof net from moving and to block the entry and accumulation of dust during operation to affect the normal operation of the equipment.

[0042] A cylinder flush with the front - end face is provided at the center of the 1 - installation main body part, which is matched with the inner holes of the 2 - seal seat and the 5 - copper triangular pressing block. And a threaded hole is provided inside the cylinder, and the 12 - displacement detection switch assembly and the 13 - switch trigger part one are installed. The 13 - switch trigger part one is provided with an inner hole and a long - strip notch for installing and limiting the 14 - switch trigger part two. A hole for installing and fixing the 23 - trigger spring is provided inside the 14 - switch trigger part two. The inner wall of the 1 - installation main body part is provided with three groups of pressure - relief grooves. And the bottom - end face is provided with a wire groove and a counterbore. The 19 - fixing nut for installing and fixing the 12 - displacement detection switch assembly is installed in the counterbore, and the 24 - rear mounting plate is installed on the bottom - end face. A mounting threaded hole is provided at the rear end of the outer cylindrical surface of the 1 - installation main body part, and the 16 - air - pipe joint and the 17 - pressure - relief valve are installed. A cut - surface is provided on the outer cylindrical surface of the 1 - installation main body part and the 15 - circuit - board mounting seat is installed. The 21 - induction circuit board is installed inside the 15 - circuit - board mounting seat, and a threaded hole is provided on its side and the 18 - signal joint is installed.

[0043] A counterbore is provided on the front end face of the 5-copper triangular pressing block to contact and cooperate with the bottom end face of the 14-switch trigger part II; and the impact induction sensitivity is adjusted by changing the distance between the switch and the bottom end face of the 14-switch trigger part II by adjusting the position of the 12-displacement detection switch assembly; and the clearance between the front round rod of the 9-rocker arm and the inner hole of the 7-end cap bushing is greater than the distance when the 9-rocker arm swings to the limit position; and the clearance between the rear end face of the 25-front mounting plate installed on the front end face of the front round rod of the 9-rocker arm and the end face of the 11-dust-proof net cover plate is greater than the distance when the 9-rocker arm swings to the limit position.

[0044] Working principle:

[0045] When the laser device is operating normally, the 16-air pipe joint connects the air pipe to introduce compressed gas into the 1-mounting main body, and the six 22-buffer springs are partially compressed. These two provide gas pressure and spring pressure for the bottom of the 2-reset support seat, so that the 2-reset support seat is pushed outwards, and the 5-copper triangular pressing block installed on the 2-reset support seat is also driven to push up the 9-rocker arm, so that the 10-positioning module installed on the 9-rocker arm moves to the lowest point of the 8-limit sleeve groove surface and contacts and cooperates with it to keep the laser head stable during operation and work.

[0046] When an impact accident occurs to the laser head, depending on the direction of the impact, the 9-rocker arm will rotate, swing or directly displace in the corresponding direction. These actions will drive the 2-reset support seat to move backward, and also drive the 5-copper triangular pressing block to move backward, no longer supporting the 14-switch trigger part II. The unsupported 14-switch trigger part II is ejected by the relaxation of the 23-trigger spring to contact and trigger the 12-displacement detection switch assembly. This signal is sent to the control system through a wire, and the device immediately stops running and quickly raises the laser head to avoid causing secondary damage. When the 2-reset support seat moves backward, the sealed gas inside the 1-mounting main body is quickly compressed, and at the same time the six 22-buffer springs are further compressed. The reaction force generated in this process effectively absorbs the impact energy and plays a buffering and protecting role. And because of the pressure relief groove provided on the inner wall of the 1-mounting main body and the 17-pressure relief valve installed on its outer cylindrical surface, it can prevent the pressure inside the 1-mounting main body from being greater than the impact force, resulting in the inability to play a buffering role.

[0047] In addition, due to the contact and fit design between the 10-positioning module installed on the 9-rocker arm and the groove surface of the 8-limit sleeve, and the limiting effect of the end face of the 6-front end cover mounting ring groove and the bottom end face of the 7-end cover bushing, when the impact factor is eliminated, under the action of air pressure and the spring, after the impact factor is eliminated, the 10-positioning module installed on the 9-rocker arm can slide back to the origin along the V-shaped notch at the rear end of the 8-limit sleeve for automatic reset. Moreover, the V-shaped notch at the rear end of the 8-limit sleeve is provided with an inclined surface for internal draft to ensure the reset accuracy of the 9-rocker arm and the 10-positioning module, ensuring that the laser head can quickly return to the normal working state, thus ensuring the stability and reliability of the equipment.

[0048] Embodiment 1

[0049] As Figure 9 shown, when a left-right direction impact accident occurs to the laser device, when encountering an up-down partial deflection impact, it will cause the 26-laser head to deflect. The deflection of the 26-laser head drives the 9-rocker arm to rotate. The 10-positioning module on the 9-rocker arm slides backward along the groove edge of the 8-limit sleeve. At the same time, it also presses the 2-reset support seat and the 5-copper triangular pressing block backward. The internal sealed gas of the 1-main body and the six 22-buffer springs are compressed to play a buffering role. And there are three pressure relief grooves inside the 1-main body. When the 2-reset support seat drops to a certain distance, the pressure relief grooves are exposed for exhaust, so as to prevent the internal reaction force from being too large to play a buffering role and damage the laser head. And the 14-switch trigger part two loses the support of the 5-triangular pressing block and is also pressed backward by the 23-trigger spring until it abuts against and triggers the switch on the 12-displacement detection switch assembly. The 12-displacement detection switch assembly sends an alarm signal, and the machine tool control system receives it and immediately stops running. When the impact factor is eliminated, under the action of air pressure and the 22-buffer springs, the 2-reset support seat is jacked up, driving the 9-rocker arm to move backward, and making the 10-positioning module on the 9-rocker arm slide into the bottom of the groove along the groove surface of the 8-limit sleeve. And the groove surface on the 8-limit sleeve is designed with internal draft to ensure that the 10-positioning module will not slide outwards. And the bottom end face of the 7-end cover bushing is slightly higher than the lowest point of the V-shaped notch on the 8-limit sleeve to cooperate with the 10-positioning module. This design can ensure that the 10-positioning module will not slide inwards. When the 26-laser head leaves the collision object, under the action of air pressure and the spring, after the impact factor is eliminated, the 10-positioning module installed on the 9-rocker arm can slide back to the origin along the V-shaped notch at the rear end of the 8-limit sleeve for automatic reset. Moreover, the V-shaped notch at the rear end of the 8-limit sleeve is provided with an inclined surface for internal draft to ensure the reset accuracy of the 9-rocker arm and the 10-positioning module, ensuring that the laser head can quickly return to the normal working state. Automatic reset is completed without manual reset, reducing manual intervention and reducing the number of operators entering the machine tool working area, greatly improving safety.

[0050] When the middle part is hit, it will cause the 9-arm rocker to swing left and right. Due to the inclined plane design at the bottom of the 9-arm rocker, when the left and right swing position of the 9-arm rocker exceeds the gap with the 2-reset support seat, it will cause the 2-reset support seat to press downwards. The sealed gas inside the 1-main body and the six 22-buffer springs are compressed to play a buffering role, and the rest of the components are also driven to move backward, triggering the 12-displacement detection switch assembly, and the device alarms and stops.

[0051] Embodiment 2

[0052] As Figure 10 shown, when a front-back direction impact accident occurs to the laser device, when the upper and lower parts are hit, it will drive the 9-arm rocker to swing up and down. When the up and down swing position exceeds the gap between the 9-arm rocker and the 2-reset support seat, it will cause the 2-reset support seat to press downwards. The sealed gas inside the 1-main body and the six 22-buffer springs are compressed to play a buffering role, and the rest of the components are also driven to move backward, triggering the 12-displacement detection switch assembly, and the device alarms and stops.

[0053] When the middle part is hit, the 9-arm rocker is directly driven to move backward by the impact, and the impact protection effect is the same as above.

[0054] Embodiment 3

[0055] As Figure 11 shown, when an up-down direction impact accident occurs to the laser device, it will drive the 9-arm rocker to swing up and down. When the up and down swing position exceeds the gap between the 9-arm rocker and the 2-reset support seat, it will cause the 2-reset support seat to press downwards. The sealed gas inside the 1-main body and the six 22-buffer springs are compressed to play a buffering role, and the rest of the components are also driven to move backward, triggering the 12-displacement detection switch assembly, and the device alarms and stops.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
