Description

Technical Field

[0001] This invention relates to a laser cutting machine tool for processing elevator door panels, belonging to the field of laser processing technology. Background Technology

[0002] An elevator is a vertical transportation device that transports people or goods. Elevators serve buildings with designated floors. A vertical elevator has a car that runs between at least two vertical or inclined rigid guide rails with an angle of less than 15°, facilitating passenger entry and exit or loading and unloading of goods. According to speed, elevators can be divided into low-speed elevators, fast elevators, and high-speed elevators.

[0003] Modern elevators mainly consist of a traction machine (winch), guide rails, counterweight, safety devices (such as speed governors, safety brakes, and buffers), signal control system, car, and landing doors. These components are installed in the building's hoistway and machine room, respectively. They typically use friction drive with steel wire ropes. The steel wire ropes pass around the traction sheave, with each end connected to the car and the counterweight, respectively. The motor drives the traction sheave to raise and lower the car. Elevators are required to be safe and reliable, have high transport efficiency, accurate leveling, and comfortable to ride in. The basic parameters of an elevator mainly include rated load capacity, passenger capacity, rated speed, car dimensions, and hoistway type.

[0004] Elevator doors are a very important part of an elevator. There are two types of doors: the one that can be seen from the outside of the elevator and is fixed to each floor is called the hall door, and the one that can be seen from the inside of the elevator and is fixed to the car and moves with the car is called the car door.

[0005] Elevator door panels are an important component of elevators. During production, elevator door panels require cutting. To ensure the flatness of the cut, laser cutting is usually used. However, due to the high precision requirements of elevator door panel cutting, it is not easy to quickly limit the elevator door panel during the cutting process. Elevator door panels are large and heavy, making them difficult to transport and accurately position during cutting, which can affect the processing accuracy and increase the processing difficulty. Odors generated during the cutting process can easily spread, and air circulation in the workshop may prevent the odors from being completely absorbed, thus affecting the air quality in the workshop. Furthermore, the cut parts are not easy to remove, affecting subsequent operations and reducing the efficiency of laser cutting elevator door panels. Summary of the Invention

[0042] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0043] like Figure 1-10 As shown, the laser cutting machine tool for processing elevator door panels includes:

[0044] A frame assembly 100 is composed of a machine tool 101. A frame 103 is fixedly installed on the top of the machine tool 101, and a conveying mechanism is provided inside the machine tool 101.

[0045] The positioning component 200 consists of a clamping mechanism and a pressing mechanism. The clamping mechanism is fixedly installed on the top surface of the frame 103, and the pressing mechanism is rotatably connected to the top surface of the frame 103. The machine tool 101 is equipped with a control mechanism, which is connected to the pressing mechanism.

[0046] Mounting assembly 300 is fixedly mounted to the middle side wall of machine tool 101. Mounting assembly 300 consists of a vertical plate 301 and a horizontal plate 303. The vertical plate 301 is fixedly connected to the outer wall of machine tool 101. The top of the vertical plate 301 is fixedly connected to the horizontal plate 303. A cutting device is movably sleeved on the surface of the horizontal plate 303. The cutting device includes a main body 305. The main body 305 slides against the bottom surface of the horizontal plate 303.

[0047] An air intake assembly 400 is fixedly installed on the side wall of the main body 305. The air intake assembly 400 is composed of a flow guide 401, which is symmetrically arranged on both sides of the main body 305. The interior of the flow guide 401 is connected to the ventilation structure, and the ventilation structure extends into the interior of the main body 305 and communicates with the annular pipe 411. The annular pipe 411 is fixedly installed inside the bottom end of the main body 305.

[0048] The material discharge assembly 500 is fixedly installed on the top surface of the frame 103. The material discharge assembly 500 is correspondingly arranged on one side of the installation assembly 300, and a feeding mechanism is slidably connected to the material discharge assembly 500.

[0049] The machine tool 101 has several evenly distributed support legs 102 at its bottom. The top edge of the machine tool 101 is wrapped with a frame 103, and both ends of the frame 103 are fixedly installed with placement plates 104 for placing door panels 108. The conveying mechanism is located between two placement plates 104. The inner wall of the machine tool 101 is rotatably connected with multiple evenly distributed support rollers 109, and each support roller 109 is located inside the conveying mechanism. The conveying mechanism consists of a drive device 105 and a drive shaft 106. The drive device 105 is fixedly installed to the outer wall of the frame 103. The output end of the drive device 105 passes through the frame 103 and the machine tool 101 and is fixedly connected to the drive shaft 106. The drive shaft 106 is rotatably connected to the inner wall of the machine tool 101. Both ends of the drive shaft 106 are fixedly installed with sprockets. The sprockets are driven by chains, and each independent block of the chain is fixedly connected to a support mesh chain 107. The surface of the support roller 109 is in contact with the support mesh chain 107.

[0050] In this technical solution, the placement plate 104 is used to place the door panel 108. After the conveying mechanism is started, the door panel 108 is pushed onto the support mesh chain 107. The door panel 108 is conveyed by the support mesh chain 107. When the drive device 105 is started, it drives the sprocket on the drive shaft 106 to rotate, which in turn drives the support mesh chain 107 on the chain to rotate synchronously, thereby realizing the conveying of the door panel 108. During the conveying process, the support mesh chain 107 is supported by the support roller 109 to ensure the stability of the conveying process. At the same time, it can ensure its effective fixation when pressed and limited in the future.

[0051] The clamping mechanism consists of a fixed base 201, which is fixedly installed on the top surface of the frame 103. The fixed base 201 is fixedly connected to a first electric push rod 202. A positioning plate 203 is fixedly connected to the telescopic end of the first electric push rod 202. There are two positioning plates 203, both L-shaped, which are correspondingly positioned on the surface of the support mesh chain 107. The pressing mechanism includes a rotating rod 204 and a pressure plate 205. The rotating rod 204 is rotatably connected to the top surface of the frame 103, and the other end of the rotating rod 204 is fixedly connected to the pressure plate 205. Rotating rods 204 are arranged on both sides of the clamping mechanism. Each rotating rod 204 has an elongated hole 206 in the middle. The control mechanism is arranged inside the elongated hole 206. The control mechanism consists of a first cylinder 207. The first cylinder 207 is fixedly installed inside the machine tool 101. The telescopic end of the first cylinder 207 is fixedly connected to the connecting rod 208. The connecting rod 208 is inserted through the machine tool 101 and the guardrail and extends into the elongated hole 206. Two ends 209 are fixedly connected to the top of the connecting rod 208, and the two ends 209 are located on both sides of the rotating rod 204.

[0052] In this technical solution, after the door panel 108 is transported to the bottom of the cutting device, the drive device 105 stops working, and then the first electric push rod 202 on the fixed base 201 is activated, which pushes the positioning plate 203 against both sides of the door panel 108. Then the first cylinder 207 is activated, and when it shortens, it drives the end 209 on the connecting rod 208 to move down. The end 209 presses the rotating rod 204 and drives the pressure plate 205 to press against the two sides of the door panel 108, thereby pressing the door panel 108 onto the support roller 109 to achieve stable fixation and provide accuracy for subsequent laser cutting.

[0053] The vertical plate 301 is fixedly connected to the horizontal plate 303 via reinforcing ribs 302. A rack 304 is provided on the top surface of the horizontal plate 303. A U-shaped sleeve plate 306 is fixedly installed on the top of the main body 305. The sleeve plate 306 is movably sleeved with the surfaces of the horizontal plate 303 and the rack 304. The top of the sleeve plate 306 is fixedly connected to a first motor 307. The output end of the first motor 307 is fixedly connected to a first gear 308. The first gear 308 meshes with the rack 304. A partition plate 309 is fixedly installed inside the main body 305. A laser device 310 and a housing 311 are respectively installed on both sides of the partition plate 309. Several openings are provided at the bottom of the main body 305. The annular structure of air holes 312 is evenly distributed, and the air holes 312 are distributed correspondingly to the annular tube 411. The bottom of the annular tube 411 is provided with a connecting nozzle 412 corresponding to the air holes 312, and the annular tube 411 is located outside the shell 311. A second electric push rod 409 is fixedly installed on the top of the main body 305. The telescopic end of the second electric push rod 409 is fixedly connected to an L-shaped movable plate 408. The movable plate 408 is movably sleeved with a limiting plate 407, and the limiting plate 407 is fixedly installed to the outer wall of the main body 305. The bottom of the movable plate 408 is fixedly connected to a bottom plate 410, and the bottom plate 410 is located below the main body 305.

[0054] In this technical solution, the cutting device can be moved on the horizontal plate 303 for position adjustment. It can be adjusted appropriately according to the cutting needs, and then a rectangular hole is cut out by the cutting device for installing the control panel. At the same time, the gas at the cutting position can be absorbed during the cutting process.

[0055] Specifically, such as Figure 9 As shown, in one embodiment, there are two vertical plates 301 and they are arranged on both sides of the machine tool 101. Both ends of the horizontal plate 303 are connected to the vertical plates 301 to ensure the stability of the laser device 310 when it moves on the horizontal beam 303.

[0056] Furthermore, when adjusting the cutting position, the first motor 307 is started to drive the first gear 308 to rotate. When the first gear 308 rotates on the rack 304, it drives the sleeve 306 to slide on the surface of the horizontal plate 303, thereby adjusting the position of the main body 305 to achieve precise cutting control.

[0057] The ventilation structure consists of a first air inlet pipe 402 and a second air inlet pipe 404. The first air inlet pipe 402 is a U-shaped structure and is disposed on the surface of the limiting plate 407. Both ends of the first air inlet pipe 402 are fixedly connected to the guide shroud 401. The middle part of the first air inlet pipe 402 is connected to the second air inlet pipe 404 through the connecting pipe 403. The second air inlet pipe 404 and the connecting pipe 403 are both fixedly connected to the control valve 406. One end of the second air inlet pipe 404 is fixedly connected to the negative pressure pump 405, and the negative pressure pump 405 is located on one side of the movable plate 408 and fixedly installed on the top of the main body 305. The other end of the second air inlet pipe 404 passes through the main body 305 and is fixedly connected to the annular pipe 411.

[0058] In this technical solution, the negative pressure pump 405 is started simultaneously with the cutting. When the negative pressure pump 405 is working, the gas in the annular pipe 411 enters the second air inlet pipe 404, thereby achieving gas discharge. At this time, the air below the main body 305 enters the air hole 312 and enters the annular pipe 411 through the connecting nozzle 412, thereby absorbing the air below the main body 305 and facilitating the subsequent collection and treatment of the discharged air. When the cutting speed is fast or the workshop air flow is large, it is difficult for all the gas generated by the cutting to be absorbed. At this time, the control valve 406 on the second air inlet pipe 404 is opened and closed, and the control valve 406 on the connecting pipe 403 is opened, so that the gas enters from the guide shroud 401, and enters the second air inlet pipe 404 through the first air inlet pipe 402 and the connecting pipe 403 before being discharged and collected. The guide shroud 401 can expand the absorption area around the main body 305, prevent the leakage of gas generated by the cutting, and improve the absorption effect.

[0059] The discharge assembly 500 consists of a crossbeam 501, which is U-shaped and fixedly connected to the top surface of the frame 103. A toothed plate 502 is fixedly installed on the top of the crossbeam 501 and located inside the crossbeam 501. A feeding mechanism is slidably connected to the surface of the crossbeam 501. The feeding mechanism consists of a slide block 503, which is slidably connected to the surface of the crossbeam 501. The slide block 503 has a gap separating it from the toothed plate 502. The sidewall of the slide block 503 is fixed. A second motor 504 is installed, and the output end of the second motor 504 is fixedly connected to a second gear 505. The second gear 505 is meshed with a toothed plate 502. A second cylinder 506 is fixedly installed on the other side wall of the slide block 503. The telescopic end of the second cylinder 506 is fixedly connected to a connecting plate 507. A suction cup 508 is fixedly connected to the bottom of the connecting plate 507. The suction cup 508 is connected to an exhaust pipe 509, and the exhaust pipe 509 is fixedly connected to the connecting plate 507.

[0060] In this technical solution, after the cutting is completed, the support chain 107 drives the door panel 108 to continue to be conveyed. At this time, the second motor 504 works to drive the second gear 505 to rotate. When the second gear 505 rotates on the toothed plate 502, it drives the slide 503 to adjust its position. When the cutting position is below the suction cup 508, the second cylinder 506 is activated to drive the suction cup 508 on the connecting plate 507 to contact the cutting position. After the air in the exhaust pipe 509 is discharged by the air pump, the negative pressure generated achieves the adsorption of the cutting part. The second cylinder 506 shortens and drives the cutting waste to be removed, which is convenient to separate from the door panel 108 and facilitates subsequent processing.

The protection scope of this invention is defined by the appended claims.
