Description

Technical Field

[0001] This utility model relates to the field of beveling technology, specifically a beveling cutting device. Background Technology

[0002] my country has abundant mineral resources. With the development and progress of science and technology, screening equipment is gradually developing towards higher quality and longer service life. Screening equipment has many complex parts, including a large number of welded parts. In order to ensure the quality requirements of the welded parts of screening equipment, beveling has always been an essential process step for large welded parts.

[0003] Current beveling methods include milling, flame cutting, and laser cutting. The problem with milling is the long processing time, which limits the milling machine's capacity. Flame cutting results in a rough cut, requiring secondary grinding with an angle grinder, which is cumbersome and time-consuming. Laser cutting is hampered by the high cost of laser cutting equipment, increasing processing costs. Therefore, a low-cost beveling device is needed on-site. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bevel cutting device with low manufacturing cost and good performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A bevel cutting device includes a platform support with a cutting platform on it. A trolley track is located on the right side of the cutting platform, and a cutting trolley is mounted on the trolley track via a support frame. The platform support also includes a vertical lifting mechanism with a support plate located below and parallel to the cutting platform. The support plate has several universal balls, and the cutting platform has several through holes corresponding to the universal balls. When the vertical lifting mechanism moves the support plate to the bottom surface of the cutting platform, the upper part of the universal balls protrudes through the through holes onto the top surface of the cutting platform. The platform support also includes an inclined lifting mechanism with a limiting plate.

[0007] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0008] After the upper part of the omnidirectional ball is exposed above the top surface of the cutting platform, it is easy to slide the workpiece to be worked to the limiting plate. After the workpiece is in place, the pallet is lowered and the working steel plate falls directly onto the cutting platform. The cutting trolley can then be used to process the bevel along the trolley track. This facilitates the movement and positioning of the workpiece, facilitates bevel processing, and the device has low manufacturing cost and wide applicability.

[0009] As a preferred embodiment, a further technical solution of this utility model is:

[0010] Preferably, the limiting plate includes an L-shaped corner plate with a length greater than or equal to the width of the cutting platform. A baffle is provided at each end of the corner plate, and a hinge hole is provided on the baffle. A hinge shaft is provided on the cutting platform corresponding to the hinge hole. The baffle is hinged to the cutting platform via the hinge shaft. The corner plate also has a connecting lug, and the output end of the inclined lifting mechanism is hinged to the corner plate via the connecting lug. When the inclined lifting mechanism rotates the corner plate around the hinge shaft, and the first side plate of the corner plate abuts against the bottom surface of the cutting platform, the second side plate of the corner plate is perpendicular to the cutting platform, and its upper edge extends above the top surface of the cutting platform. The second side plate serves to limit the movement of the workpiece.

[0011] Preferably, several sets of hinge shafts are symmetrically arranged on both sides of the cutting platform, with two in each set; this facilitates the adjustment of the end position of the workpiece to be operated, thereby playing the role of adjusting the beveling position.

[0012] Preferably, the second side plate is provided with a first magnet, which serves to limit the movement of the workpiece.

[0013] Preferably, a second magnet is provided on the cutting platform, and the top surface of the second magnet is not higher than the surface of the cutting platform.

[0014] Preferably, the second magnet is an electromagnet; when energized, it can fix the position of the workpiece to be worked on, preventing the workpiece from moving during the beveling process. Attached Figure Description

[0022] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, this embodiment provides a beveling cutting device, including a platform support 1, a cutting platform 2 mounted on the platform support 1, a trolley track 13 located on the right side of the cutting platform 2, the trolley track 13 being mounted on the cutting platform 2 via a support frame 3, and a cutting trolley 14 being mounted on the trolley track 13; the platform support 1 also includes a vertical lifting mechanism 4, with a support plate 5 located below and parallel to the cutting platform 2; the support plate 5 has several universal balls 6, and the cutting platform 2 has several through holes 201 corresponding to the universal balls 6; the platform support 1 also includes an inclined lifting mechanism 7, the lower end of which is hinged to the platform support 1, and the upper end is the output end, with a limit plate 8 hinged to the output end. The vertical lifting mechanism 4 and the inclined lifting mechanism 7 can be driven by hydraulic cylinders, pneumatic cylinders, electric actuators, etc.; appropriate devices can be purchased according to the output stroke requirements.

[0024] When the vertical lifting mechanism 4 outputs, it drives the support plate 5 to move until the support plate 5 abuts against the bottom surface of the cutting platform 2. At the same time, the upper part of the universal ball 6 protrudes from the top surface of the cutting platform 2 through the through hole 201. Simultaneously, when the inclined lifting mechanism 7 outputs, it drives the limiting plate 8 to rotate. In this embodiment, the side section of the limiting plate 8 is L-shaped. When the inclined lifting mechanism 7 drives the limiting plate 8 to rotate until the limiting plate 8 is right-angled and locked at the right side of the cutting platform 2, the second side plate 802 of the limiting plate 8 is perpendicular to the cutting platform 2. Figure 3 Place the workpiece to be processed on the cutting platform 2, and slide the ball of the universal ball 6 that is exposed on the table surface of the cutting platform 2 to the right until it abuts against the second side plate 802 of the limiting plate 8. Then the cutting trolley 14 can perform beveling cutting along the trolley track 13.

[0025] This embodiment discloses a specific connection structure for the limiting plate 8, such as... Figure 2 , Figure 3As shown, the limiting plate 8 includes an L-shaped corner plate with a side cross-section. The corner plate can be made of angle steel or welded from two long steel plates. The length of the corner plate is greater than or equal to the width of the cutting platform 2. A baffle 9 is provided at each end of the corner plate. The baffle 9 is provided with a hinge hole. A hinge shaft is provided on the cutting platform 2 corresponding to the hinge hole. The baffle 9 is hinged to the cutting platform 2 through the hinge shaft. The corner plate is also provided with a connecting ear 10. The output end of the inclined lifting mechanism 7 is hinged to the corner plate through the connecting ear 10. The inclined lifting mechanism 7 rotates the corner plate around the hinge shaft. When the first side plate 801 of the corner plate abuts against the bottom surface of the cutting platform 2, the second side plate 802 of the corner plate is perpendicular to the cutting platform 2 and its upper edge is higher than the top surface of the cutting platform 2. The second side plate 802 plays a limiting role for the workpiece 12 to be operated.

[0026] In this embodiment, several sets of hinge shafts are symmetrically arranged on both sides of the cutting platform 2, with two in each set; by connecting the baffle 9 to the hinge shafts at different positions, the distance between the second side plate 802 and the right side of the cutting platform 2 can be adjusted, which facilitates the adjustment of the end position of the workpiece 12 to be operated, thereby playing the role of adjusting the bevel processing position.

[0027] Furthermore, a first magnet is provided on the second side plate 802; it serves to limit the movement of the workpiece 12 to be worked on.

[0028] In this embodiment, a second magnet is also provided on the cutting platform 2. The top surface of the second magnet is not higher than the table surface of the cutting platform 2. The second magnet is an electromagnet. After the workpiece 12 to be worked is moved into place, the output end of the vertical lifting mechanism 4 retracts, and the universal ball 6 descends to the bottom of the cutting platform 2. When the workpiece 12 to be worked falls onto the cutting platform 2, the second magnet is energized to fix the position of the workpiece 12 to be worked, preventing the workpiece 12 to be worked from moving during the beveling process.

[0029] In this embodiment, guide holes 501 are also machined on the cutting platform 2 and the pallet 5. Guide pins 11 are installed through the guide holes 501 to connect the cutting platform 2 and the pallet 5 and to limit the movement of the pallet 5 up and down.

[0030] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
