Description

Technical Field

[0001] This utility model relates to the technical field of CNC large vertical lathe tools, specifically an automatic chip removal device for CNC large vertical lathes. Background Technology

[0002] Automatic chip removal devices for CNC large vertical lathes are auxiliary functional devices installed in the machining area of ​​CNC large vertical lathes (hereinafter referred to as "CNC large vertical lathes"). They automatically collect, transport and discharge metal chips generated during the machining process through mechanical transmission, fluid power or a combination of methods, so as to ensure the normal operation of the machine tool and improve machining accuracy and safety.

[0003] Existing automatic chip removal devices mostly discharge the collected chips directly into a small carriage during operation. However, this results in large gaps between the chips, causing the carriage to fill up easily. This necessitates changing the carriage, which is cumbersome and affects the working efficiency of large CNC vertical lathes, failing to meet user needs. To address these issues, we propose technological innovations based on existing chip removal devices. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic chip removal device for large CNC vertical lathes, so as to solve the problem mentioned in the background art that the general chip removal device cannot well meet people's needs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic chip removal device for a large CNC vertical lathe, comprising a transmission component, an extrusion component disposed on the upper right side of the transmission component, and a pushing component mounted on the left wall of the extrusion component, the pushing component comprising a telescopic plate, a pushing plate and multiple hydraulic cylinders, wherein the lower end of the telescopic plate is connected to the pushing plate, and the left side of the pushing plate is connected to multiple hydraulic cylinders.

[0006] Furthermore, a feeding component is installed on the right side of the extrusion component, and elastic traction reset components are installed at both the front and rear ends of the extrusion component.

[0007] Furthermore, the transmission component includes a wire mesh cage, a conveyor belt, and a spiral elevator, with the conveyor belt installed on the upper left side of the wire mesh cage and the spiral elevator installed on the upper right side of the wire mesh cage.

[0008] Furthermore, the extrusion assembly includes a receiving box, a weighing sensor, and an upper support plate, and the weighing sensor is installed on the lower inner wall of the receiving box, and the upper support plate is provided at the upper end of the weighing sensor.

[0009] Furthermore, the feeding assembly includes a feeding gate, an L-shaped metal plate, and an electromagnet, with the L-shaped metal plate connected to the right end of the feeding gate and the electromagnet connected to the upper end of the L-shaped metal plate.

[0010] Furthermore, the elastic traction reset assembly includes an air box, a spring, a piston plate, and an air pipe, with a spring installed inside the air box, the lower end of the spring connected to the piston plate, and the lower end of the air box connected to the air pipe.

[0011] Furthermore, the elastic traction reset assembly also includes an outer sleeve tube, a middle sleeve tube, an inner sleeve rod, and a connecting block. The end of the air pipe away from the air box is connected to the outer sleeve tube. The inner sleeve tube is connected to the inside of the outer sleeve tube, and the inner sleeve rod is connected to the inside of the middle sleeve tube. The right end of the inner sleeve rod is connected to the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the device has a chip pressurization effect, which compresses the chips into blocks, thereby reducing the space occupied by the chips and facilitating long-term operation of the device. The device can adjust the compressing force through magnetic force and automatically reset through the elastic structure, which facilitates the automated operation of the device.

[0013] 1. In this utility model, after a certain amount of material is stored inside the extrusion assembly, multiple hydraulic cylinders will push the push plate, thereby extruding the metal scraps and forming them into blocks, which then fall into the collection cart below. This extrusion reduces the space occupied by the scraps, avoiding the need for workers to frequently empty the scraps and waste time. At the same time, the blocky scraps are easy to place. The telescopic plate can act as a shield during the extrusion process, preventing the continuing to fall scraps from leaking out of the equipment. Thus, the CNC large vertical lathe does not need to be stopped during the extrusion process.

[0014] 2. This utility model uses the magnetic attraction force of an electromagnet to the L-shaped metal plate to control the extrusion force of the equipment, which makes it easier to form chips. At the same time, the elastic structure of the spring can pull back the piston plate, so that the discharge gate will be automatically reset after the material is discharged, which facilitates the continuous operation of the equipment.

Detailed Implementation

[0021] like Figure 1 and Figure 3 As shown, an automatic chip removal device for a large CNC vertical lathe includes a transmission component 1, an extrusion component 2 is provided on the upper right side of the transmission component 1, and a pushing component 4 is installed on the left wall of the extrusion component 2. The pushing component 4 includes a telescopic plate 401, a pushing plate 402 and a multi-section hydraulic cylinder 403, and the lower end of the telescopic plate 401 is connected to the pushing plate 402, and the left side of the pushing plate 402 is connected to the multi-section hydraulic cylinder 403.

[0022] The multi-section hydraulic cylinder 403 is connected to the screw conveyor 103 to facilitate the force distribution when the multi-section hydraulic cylinder 403 is working. The push plate 402 is rotatably connected to the telescopic plate 401, and the telescopic plate 401 is also rotatably connected to the receiving box 201. In this way, when the push plate 402 pushes, the lower end of the telescopic plate 401 will move with the push plate 402. This way, the telescopic plate 401 will block the falling debris and prevent the debris from falling to the left side of the push plate 402, thus preventing the debris from leaking out.

[0023] After a certain amount of material is stored inside the extrusion assembly 2, the multi-section hydraulic cylinder 403 pushes the push plate 402, thereby extruding the metal scraps into blocks, which then fall into the collection cart below. This extrusion reduces the space occupied by the scraps, avoiding the need for workers to frequently empty the scraps and waste time. At the same time, the blocky scraps are easy to place. The telescopic plate 401 can act as a shield during the extrusion process, preventing the continuing to fall scraps from leaking out of the equipment. Therefore, the CNC large vertical lathe does not need to be stopped during the extrusion process.

[0024] like Figure 1 As shown, the transmission component 1 includes a wire mesh box 101, a conveyor belt 102 and a spiral elevator 103, and the conveyor belt 102 is installed on the upper left side of the wire mesh box 101, and the spiral elevator 103 is installed on the upper right side of the wire mesh box 101.

[0025] The conveyor belt 102 is installed under the large CNC vertical lathe to collect debris. At the same time, the wire mesh box 101 is designed to be hollow so that water on the debris conveyed by the conveyor belt 102 can also be drained out, preventing the cutting fluid from leaking out and affecting the operation of the equipment.

[0026] like Figure 4 As shown, the extrusion assembly 2 includes a housing 201, a weighing sensor 202 and an upper support plate 203. The weighing sensor 202 is installed on the lower inner wall of the housing 201, and the upper support plate 203 is provided on the upper end of the weighing sensor 202.

[0027] The load cells 202 are arranged around the bottom of the upper support plate 203. This allows the load cells 202 to accurately weigh the debris above the upper support plate 203, thereby enabling intelligent control of the equipment and facilitating its operation.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, a feeding component 3 is installed on the right side of the extrusion component 2, and elastic traction reset components 5 are installed at both the front and rear ends of the extrusion component 2.

[0029] like Figure 4 As shown, the feeding assembly 3 includes a feeding gate 301, an L-shaped metal plate 302, and an electromagnet 303. The right end of the feeding gate 301 is connected to the L-shaped metal plate 302, and the upper end of the L-shaped metal plate 302 is connected to the electromagnet 303.

[0030] The magnetic force of electromagnet 303 can be adjusted according to the magnitude of the current. The magnetic force of electromagnet 303 can be adjusted according to the specific situation, thereby adjusting the magnetic attraction of electromagnet 303 to metal plate 302. This will adjust the squeezing force between the feeding gate 301 and the push plate 402, making it easier for the equipment to squeeze and shape the scrap.

[0031] The magnetic attraction of the electromagnet 303 to the L-shaped metal plate 302 can control the extrusion force of the equipment, making it easier to form chips. At the same time, the elastic structure of the spring 502 can pull back the piston plate 503, so that the discharge gate 301 will be automatically reset after the material is discharged, which facilitates the continuous operation of the equipment.

[0032] like Figure 5As shown, the elastic traction reset assembly 5 includes an air box 501, a spring 502, a piston plate 503, and an air pipe 504. The spring 502 is installed inside the air box 501. The lower end of the spring 502 is connected to the piston plate 503. The lower end of the air box 501 is connected to the air pipe 504. The elastic traction reset assembly 5 also includes an outer sleeve tube 505, a middle sleeve tube 506, an inner sleeve rod 507, and a connecting block 508. The end of the air pipe 504 away from the air box 501 is connected to the outer sleeve tube 505. The middle sleeve tube 506 is connected inside the outer sleeve tube 505. The inner sleeve rod 507 is connected inside the middle sleeve tube 506. The right end of the inner sleeve rod 507 is connected to the connecting block 508.

[0033] The piston plate 503 forms an elastic structure with the air box 501 through the spring 502. The elastic structure can automatically pull the piston plate 503 back to its original position when the discharge gate 301 is unobstructed. This will cause the air pressure inside the air box 501 to decrease, thereby sucking away the gas inside the outer sleeve 505, the middle sleeve 506 and the inner sleeve rod 507 through the air pipe 504. This will cause the inner sleeve rod 507 and the middle sleeve 506 to retract back into the outer sleeve 505. In this way, the connecting block 508 will drive the discharge gate 301 to reset. The outer sleeve 505, the middle sleeve 506 and the inner sleeve rod 507 form a multi-section telescopic rod structure, similar to the telescopic structure of a cylinder.

[0034] Working principle: When using this automatic chip removal device for CNC large vertical lathes, the conveyor belt 102 is first installed under the CNC large vertical lathe. The chips washed down by the cutting fluid will fall directly onto the conveyor belt 102, which then carries them to the mesh box 101. The screw conveyor 103 then lifts the chips into the receiving box 201 for collection. When the weighing sensor 202 detects that the chips have reached a certain weight, the multi-section hydraulic cylinder 403 pushes the push plate 402, thereby removing the chips. When the extrusion force reaches a certain level, it will push the discharge gate 301, thereby squeezing out the extruded fragments. At this time, the fragments will fall into the collection trolley below the receiving box 201 due to gravity. After the fragments fall, the discharge gate 301 is no longer under force, and the spring 502 will drive the piston plate 503 to reset, thereby causing the telescopic structure composed of the outer sleeve tube 505, the middle sleeve tube 506, and the inner sleeve rod 507 to retract, thus resetting the discharge gate 301 and facilitating the continued operation of the equipment.
