Description

Technical Field

[0001] This utility model relates to a burr-cutting device for alloy castings, and specifically to a burr-cutting device for alloy castings. Background Technology

[0002] In many mechanical products, alloy castings need to be precisely assembled with other parts. If the casting has burrs, its dimensions will exceed the design requirements, resulting in reduced fitting accuracy with other parts. Burrs on alloy castings are equivalent to irregular structures. When the casting is subjected to external forces, stress concentration is likely to occur at the connection between the burrs and the main body of the casting. Removing burrs by using a burr side-cutting device can make the shape of the casting more regular, reduce stress concentration points, and thus improve the mechanical properties and service life of the casting.

[0003] The existing technology has the following problems:

[0004] In the manufacturing process of alloy castings, the deburring step is essential. Traditional methods for handling deburred irregular-shaped alloy castings mainly rely on manual operation, which is inefficient and makes it difficult to guarantee consistent quality. Existing mechanical side-cutting devices have limited mold change convenience, requiring frequent changes for different batches and shapes of castings. Furthermore, the cutting blades cannot be flexibly adjusted during side-cutting, making it difficult to adapt to different casting shapes and diverse deburring morphologies. This fails to meet the stringent requirements of modern industrial production for high precision, high capacity, and multi-variety processing. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-5 As shown, this utility model provides a burr side cutting device for alloy castings, including a device housing 1, a mold loading platform 3 is provided in the middle of the inner side of the device housing 1, and a movable side cutting device 2 is provided in the inner side of the device housing 1, with the movable side cutting device 2 located in front of the mold loading platform 3.

[0024] The outer casing 1 provides protection and support for the mold loading platform 3 and the mobile side-cutting device 2, ensuring the stable operation of the internal components. The mold loading platform 3 is responsible for firmly placing the alloy casting and maintaining the position of the casting during the burr side-cutting process, ensuring that the mobile side-cutting device 2 can accurately remove the burrs. The mobile side-cutting device 2 performs efficient side-cutting on the burrs of the casting fixed by the mold loading platform 3.

[0025] like Figure 2 As shown, this utility model provides a technical solution: Preferably, the mold loading platform 3 includes two mounting molds 33, which are parallel vertically and have opposite openings. Each of the four outer corners of the mounting mold 33 is provided with a mounting guide post 34. The top of the four upper mounting guide posts 34 is fixedly connected to a support base 32. A hydraulic column 31 is rotatably connected to the middle of the top of the support base 32. The top of the hydraulic column 31 is fixedly connected to the middle of the top of the inner side of the device housing 1. The bottom of the four lower mounting guide posts 34 is fixedly connected to a rotating base 37. The bottom of the lower mounting mold 33 is fixedly connected to two horizontally parallel magnetic strips 35. A magnetic guide groove 36 is opened at the top of the rotating base 37 at the corresponding position of the magnetic strips 35. The bottom of the rotating base 37 is rotatably connected to the bottom of the inner side of the device housing 1.

[0026] The mold loading platform 3 clamps the alloy casting through two mounting molds 33. The mounting guide column 34 provides guidance and support for the mold. The support base 32 and hydraulic column 31 assist the upper mold in lifting and lowering to adapt to castings of different heights. The rotating base 37, combined with the magnetic strip 35 and magnetic guide groove 36, realizes the rotation and positioning of the lower mold. Together, they provide stable clamping and precise positioning conditions for the burr side cutting of the alloy casting, ensuring accurate casting position and precise burr removal during the processing.

[0027] like Figure 3 As shown, this utility model provides a technical solution: Preferably, the installation guide post 34 includes a guide post body 343, the bottom end of the guide post body 343 is fixedly connected to the top end of the rotating base 37 or the bottom end of the support base 32, the installation mold 33 can be sleeved on the outer surface of the guide post body 343, the top end of the guide post body 343 is rotatably connected to a limiting turntable 342, and one end of the installation mold 33 has a rotating fixing groove 341 at the corresponding position of the guide post body 343.

[0028] like Figure 3 As shown, this utility model provides a technical solution: preferably, the guide post body 343 is an elliptical post, the limiting disc 342 has the same shape as the guide post body 343, and the rotating fixing groove 341 is circular so that the limiting disc 342 can rotate.

[0029] The installation mold 33 is fitted onto the outer surface of the guide post body 343. When the installation mold 33 is installed, it slides down along the guide post body 343 until it reaches the appropriate position. At this time, the installation mold 33 is initially positioned on the guide post body 343, preparing for further fixation and adjustment. The limiting turntable 342 rotates in the rotating fixing groove 341, so that the installation guide post 34 restricts the removal of the installation mold 33 for secondary fixation.

[0030] like Figure 4As shown, this utility model provides a technical solution: Preferably, the movable side-cutting device 2 includes a longitudinal guide post 28, which is located inside the outer casing 1 at the front right side and its upper and lower ends are fixedly connected to the inner side of the outer casing 1. A longitudinal drive threaded post 23 is provided on the left side of the longitudinal guide post 28. The longitudinal guide post 28 and the longitudinal drive threaded post 23 are parallel to each other. The longitudinal drive threaded post 23 is located inside the outer casing 1 at the front left side and its upper and lower ends are rotatably connected to the inner side of the outer casing 1. A longitudinal drive motor is provided at the bottom end of the longitudinal drive threaded post 23. A longitudinal moving beam 29 is threadedly connected to the outer surface of the longitudinal drive threaded post 23. The end of the longitudinal moving beam 29 away from the longitudinal drive threaded post 23 is slidably connected to the outer surface of the longitudinal guide post 28. A transverse drive threaded post 210 is provided in front of the longitudinal guide post 28 and the longitudinal drive threaded post 23. The transverse drive threaded post 210 is located on the lower front side inside the device housing 1 and its left and right ends are rotatably connected to the inside of the device housing 1. A transverse guide post 27 is provided above the transverse drive threaded post 210. The transverse guide post 27 is parallel to the transverse drive threaded post 210 vertically. The transverse guide post 27 is located on the upper front side inside the device housing 1 and its left and right ends are fixedly connected to the inside of the device housing 1. A transverse drive motor is provided at the left end of the transverse drive threaded post 210. A transverse moving beam 25 is threadedly connected to the outer surface of the transverse drive threaded post 210. The end of the transverse moving beam 25 away from the transverse drive threaded post 210 is slidably connected to the outer surface of the transverse guide post 27.

[0031] like Figure 4 As shown, this utility model provides a technical solution: Preferably, the longitudinal moving beam 29 and the transverse moving beam 25 are slidably connected to a connecting sliding block 26 on their outer surfaces. A hydraulic telescopic rod 24 is fixedly connected to the rear end of the connecting sliding block 26. A side cutting blade 22 is rotatably connected to the rear right end of the hydraulic telescopic rod 24. A cutting motor is provided at the left end of the side cutting blade 22. A positioning support assembly 21 is fixedly connected to the rear end of the hydraulic telescopic rod 24. The top end of the positioning support assembly 21 is located at the top end of the inner side of the device housing 1.

[0032] The longitudinal guide post 28 and the longitudinal drive threaded post 23, and the transverse guide post 27 and the transverse drive threaded post 210 work together. The motor drives the threaded post to rotate, which causes the longitudinal moving beam 29 and the transverse moving beam 25 to move precisely. This drives the connecting sliding block 26 and its hydraulic telescopic rod 24, side cutting blade 22 and other components to achieve three-dimensional spatial movement. The positioning support component 21 ensures the cutting accuracy, thereby efficiently and accurately side-cutting the burrs on the alloy casting on the mold loading table 3.

[0033] like Figure 5As shown, this utility model provides a technical solution: Preferably, the positioning support component 21 includes a guide moving groove 211, which is U-shaped and wraps around the upper mounting mold 33 on the left, right and front sides. A moving disk 212 is slidably connected to the inner side of the guide moving groove 211. A telescopic positioning column 213 is fixedly connected to the middle of the bottom end of the moving disk 212. A positioning connecting rod 214 is slidably connected inside the telescopic positioning column 213. The bottom end of the positioning connecting rod 214 extends to the outer side of the bottom end of the telescopic positioning column 213. A connecting frame 215 is fixedly connected to the bottom end of the positioning connecting rod 214. The bottom end of the connecting frame 215 is fixedly connected to the rear end of the hydraulic telescopic rod 24.

[0034] In the positioning support assembly 21, the guide moving groove 211 wraps around the upper mounting mold 33, enabling the side cutting blade 22 to cut along the left and right ends of the mounting mold 33, thus playing a guiding role. The moving disk 212 slides inside it, and the hydraulic telescopic rod 24 and the side cutting blade 22 are doubly positioned by the telescopic positioning column 213, the positioning connecting rod 214 and the connecting frame 215.

[0035] The working principle of a burr-cutting device for alloy castings will be explained in detail below.

[0036] like Figure 1-5 As shown, based on the shape and size of the alloy casting, a suitable mounting mold 33 is selected and placed over the guide post body 343 of the mounting guide post 34, allowing the mounting mold 33 to slide down to a suitable position for initial positioning. The limiting disc 342 is rotated until it engages with the rotating fixing groove 341, completing the fixing of the mounting mold 33. If the mold height needs to be adjusted, the hydraulic column 31 is controlled to extend and retract, driving the upper mounting mold 33 to rise and fall via the support base 32. For the lower mounting mold 33, the magnetic strip 35 engages with the magnetic guide groove 36 on the rotating base 37 to achieve rotation and positioning. The alloy casting is then placed between the two mounting molds 33 and clamped for fixation. Start the longitudinal drive motor and the transverse drive motor to drive the longitudinal drive threaded column 23 and the transverse drive threaded column 210 to rotate, thereby moving the longitudinal moving beam 29 and the transverse moving beam 25. Move the connecting sliding block 26 and its hydraulic telescopic rod 24 and the side cutting blade 22 to the appropriate initial position. Start the cutting motor to make the side cutting blade 22 rotate. According to the position and shape of the burr, further fine adjust the extension length of the hydraulic telescopic rod 24 to adjust the extension distance of the side cutting blade 22 to cut the left and right sides of the casting. Then, change the direction of the casting by rotating the base 37 so that the two ends that are not cut become the left and right ends for cutting.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
