Specific embodiments

[0023] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0024] "Top surface", "bottom", and "bottom surface" are referenced based on the normal use state of the cutting device, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.

[0025] As Figure 1 and 2 shown, an electric vehicle frame pipe cutting device includes a workbench 1. A plurality of conveying rollers 2 are equally spaced along the first direction on the top surface of the workbench 1. The workbench 1 is provided with a return channel 3 that penetrates up and down. Above the top opening of the return channel 3, a housing 5 with an open bottom is arranged in a lifting manner. The vertical projection of the housing 5 is located inside the top opening of the return channel 3. There is a gap between the return channel 3 and the housing 5 for the pipe to pass through. A cutting mechanism is arranged inside the housing 5. The bottom end of the return channel 3 is communicated with a liquid storage tank 6. A nozzle 703 is arranged on the inner top wall of the housing 5. The liquid storage tank 6 is communicated with the nozzle 703 through a circulation mechanism.

[0026] The above cutting device can cut the pipes used for producing the electric vehicle frame. Two hydraulic cylinders 302 are vertically arranged on the workbench 1. The lifting end of the hydraulic cylinder 302 is fixedly connected to the housing 5, and the housing 5 is driven to lift by the hydraulic cylinder 302. During use, each conveying roller 2 is controlled by a motor to rotate. The pipe is placed on each conveying roller 2 along the first direction, and the conveying roller 2 drives the pipe to pass between the return channel 3 and the housing 5 along the first direction. The part of the pipe located between the return channel 3 and the housing 5 is completely within the coverage range of the opening at the top of the return channel 3 and the opening at the bottom of the housing 5. When the pipe moves to the set length, the conveying roller 2 stops rotating, and the housing 5 descends. The cutting mechanism inside the housing 5 cuts the pipe. During cutting, the circulating mechanism sends the cutting fluid inside the liquid storage tank 6 to the nozzle 703, and the cutting fluid is sprayed onto the cutting mechanism and the pipe through the nozzle 703 to achieve the lubrication and cooling effects on the cutting mechanism, improve the cutting effect and reduce the equipment wear. At the same time, the cutting fluid can also remove the debris generated during cutting, further improving the cutting effect. During the cutting process, the return channel 3 and the housing 5 simultaneously cover the cutting mechanism, thereby reducing the splashing of debris and cutting fluid, improving the cleanliness of the cutting device, and prolonging the service life of the cutting device. The used cutting fluid enters the return channel 3 with the debris and finally returns to the inside of the liquid storage tank 6, thereby realizing the recycling of the cutting fluid and the collection of the debris, and reducing the equipment usage cost.

[0027] A further improvement is that, as Figure 2 shown, the return channel 3 is located between two of the conveying rollers 2. A notch 301 for the pipe to pass through is provided at the top end of the return channel 3, and the horizontal height of the bottom end of the notch 301 is less than or equal to the horizontal height of the top end of the conveying roller 2. When the pipe moves, it can pass through the notch 301. The pipe can be positioned through the notch 301, thereby reducing the displacement of the pipe during cutting and improving the cutting accuracy of the pipe. A plurality of notches 301 are equally spaced along the direction perpendicular to the first direction, so that multiple pipes can be positioned at one time, and a gap can be maintained between adjacent pipes through each notch 301, thereby reducing the mutual wear between the pipes during processing and facilitating the discharge of the debris generated during cutting, and reducing the accumulation of debris on the pipes.

[0028] A further improvement is that, as Figure 4As shown, the cutting mechanism includes a cutting disc 805 rotatably arranged inside the housing 5, the lower part of the cutting disc 805 is located outside the housing 5, and the housing 5 is provided with a driving member connected to the cutting disc 805. The driving member includes a motor 801 fixed on the top of the housing 5, a driving wheel 802 connected to the motor 801 is arranged inside the housing 5, and the cutting disc 805 is coaxially fixedly connected to a driven wheel 804, and the driving wheel 802 is connected to the driven wheel 804 through a transmission belt 803; when working, the motor 801 drives the driving wheel 802 to rotate, and the driving wheel 802 drives the driven wheel 804 to rotate through the transmission belt 803, and then drives the cutting disc 805 to rotate through the driven wheel 804 to achieve cutting of the pipe; during the cutting process, the cutting disc 805 located outside the housing 5 enters the inner side of the top opening of the reflux channel 3 as the cutting proceeds, so it is always covered by the housing 5 and the reflux channel 3, which can effectively reduce the splashing of debris and cutting fluid.

[0029] A further improvement is, Figure 5 As shown, both side surfaces of the cover 5 parallel to the first direction have extension portions 503 extending vertically downward, and the extension portions 503 extend to the inner side of the reflux channel 3 and slide in cooperation with the reflux channel 3. The provision of the extension portions 503 can achieve a guiding effect between the cover 5 and the reflux channel 3, improve the stability of the cover 5 when it is lifted or lowered, and at the same time, the extension portions 503 can increase the shielding range of the cover 5, and improve the shielding effect of the cover 5 on debris and cutting fluid splashing.

[0030] A further improvement is, Figure 3 and 4As shown, on both side surfaces of the housing 5 perpendicular to the first direction, there are slidingly arranged pressing plates 4. The pressing plates 4 are arranged perpendicular to the first direction and are slidably connected to the housing 5. An elastic connecting member is arranged between the pressing plates 4 and the housing 5. The elastic connecting member includes a guide rod 401 vertically and fixedly connected to the pressing plate and a guide sleeve 501 fixedly connected to the top end of the housing. The guide rod 401 is slidably matched with the guide sleeve 501. A spring 402 is sleeved on the guide rod 401. The two ends of the spring 402 are respectively connected to the guide sleeve 501 and the pressing plate 4. In this cutting device, the pressing plate 4 can extend to the inside of the return channel 3 and is slidably matched with the return channel 3. The pressing plate 4 can further increase the coverage range of the housing 5 on the cutting disc 805. Moreover, the combination of the pressing plate 4 and the extension part 503 can achieve circumferential coverage of the cutting disc 805 to reduce the splashing of debris and cutting fluid. When the housing 5 is fully raised, the cutting disc 805 completely exits from the inside of the return channel 3, enabling the pipe to pass smoothly between the return channel 3 and the housing 5. At this time, the elastic force of the spring 402 causes the pressing plate 4 to drop to the lowest point, enabling the pressing plate 4 to completely cover the cutting disc 805 inside, playing a role in protecting the cutting disc 805 and preventing the cutting disc 805 from being damaged when the pipe moves. When cutting, the housing 5 and the cutting disc 805 descend simultaneously. The pressing plate 4 can contact the pipe before the cutting disc 805. Under the action of the elastic force of the spring 402, the pressing plate 4 fixes the pipe inside the notch 301, thereby realizing the clamping and fixing of the pipe. Then the cutting disc 805 continues to descend to cut the pipe. During this process, the pressing plate 4 always fixes the pipe to improve the cutting accuracy of the pipe groove. The guide sleeve 501 plays a guiding role for the guide rod 401, thereby improving the sliding stability of the guide rod 401 and the pressing plate 4. The spring 402 always applies a downward elastic force to the pressing plate 4, thereby realizing the downward reset of the pressing plate 4 and enabling the pressing plate 4 to apply a stable thrust to the pipe to realize the fixing of the pipe.

[0031] A further improvement is that, as Figure 3 shown, a notch 301 is provided at the bottom of the pressing plate 4. The notch 301 on the pressing plate 4 is arranged opposite to the notch 301 on the return channel 3. The setting of the notch 301 can realize the positioning of the pipe. At the same time, through the setting of the notch 301, a coincident part can be generated between the pressing plate 4 and the inner wall of the return channel 3, thereby reducing the gap remaining between the two during cutting, and further reducing the splashing of debris and cutting fluid.

[0032] A further improvement is that, as Figure 1 and 3As shown, the housing 5 has vertically distributed guide grooves 502. The side of the pressing plate 4 is slidably engaged with the guide grooves 502. There is a gap for accommodating the pressing plate 4 between the return channel 3 and the housing 5. The arrangement of the guide grooves 502 can guide the pressing plate 4 and further improve the stability of the pressing plate 4. When the pressing plate 4 is connected to the return channel 3, it is located inside the return channel 3, so that the cutting fluid can fall into the inside of the return channel 3 when sliding along the pressing plate 4, thereby reducing the loss of the cutting fluid.

[0033] A further improvement is that, as Figure 1 shown, the circulation mechanism includes a circulation pipe 702 with two ends respectively connected to the nozzle 703 and the liquid storage tank 6. A power pump 701 is installed on the circulation pipe 702, and a filter screen 601 is also arranged inside the liquid storage tank 6. The filter screen 601 can separate the debris in the cutting fluid, improve the cleanliness of the cutting fluid recovered into the liquid storage tank 6. The power pump 701 provides power to send the cutting fluid to the nozzle 703 through the circulation pipe 702, thereby realizing the circulation of the cutting fluid.
