[0020] The following is a clear and complete description of the edge grinding device for cable tray production according to the present invention, with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the present invention provides a grinding device for cable tray production, including a frame 1, a grinding platform 2 installed on the surface of the frame 1, and grinding components symmetrically arranged on both sides of the grinding platform 2; at the same time, a feeding component is arranged on one side of the frame 1; the feeding component uses a lifting platform 3 and a cylinder 4 in cooperation, the lifting platform 3 transports the cable tray to the feeding position, and then the cylinder 4 pushes the cable tray into the grinding platform 2 for grinding.

[0022] The polishing assembly is mounted on the movable frame 5, and the two movable frames 5 are connected by a connecting rod. The movable frame 5 is slidably connected to the connecting rod. At the same time, the bottom of the movable frame 5 is slidably connected to the ball screw 6. The two ends of the ball screw are respectively rotatably connected to the frame 1. A drive motor 7 is installed at one end of the ball screw 6, and the drive motor 7 is fixedly connected to the frame 1. The ball screw passes through the bottom of the polishing platform 2.

[0023] In use, the ball screw 6 can be driven to rotate by the drive motor 7, thereby driving the two moving frames 5 to slide horizontally, so as to adjust the distance between the two sets of grinding components and to grind the bridge frame of different widths; it should be noted that the threads of the two moving frames 5 are opposite, so they can move towards each other at the same time or move away from each other.

[0024] By setting up two sets of grinding components and a moving frame 5 that drives the grinding components to move, not only can the two sides of the cable tray be ground simultaneously, improving grinding efficiency, but it can also perform grinding work on cable trays of different specifications, making it widely applicable.

[0025] Meanwhile, a guide rail 8 is installed on the surface of the frame 1, and the bottom of the movable frame 5 is slidably connected to the guide rail 8. The guide rail 8 also passes through the bottom of the grinding platform 2. By setting the guide rail 8, it can play a guiding and supporting role for the movable frame 5 during its movement, thereby improving its movement stability and reducing the force on the ball screw 6, thus increasing its service life.

[0026] Meanwhile, a clamping cylinder 9 is installed on the side of the grinding platform 2, and a clamping plate 10 is installed at the end of the drive shaft of the clamping cylinder 9. Through the cooperation of the clamping cylinder 9 and the clamping plate 10, the cable tray can be corrected and clamped after loading, so as to prevent it from shifting during the grinding process.

[0027] It should be noted that the polishing assembly in this embodiment includes a mounting frame 11, a polishing motor 12, and a polishing wheel 13; the polishing motor 12 is mounted on the mounting frame 11, and the polishing wheel 13 is mounted on the end of the drive shaft of the polishing motor 12. The polishing motor 12 drives the polishing wheel 13 to rotate and polish the bridge frame; the mounting frame 11 is slidably connected to the movable frame 5.

[0028] Specifically, a servo motor 14 is installed on the top of the movable frame 5. A drive bevel gear 15 is installed on the drive shaft of the servo motor 14. The drive bevel gear 15 is meshed with a driven bevel gear 16. A screw is connected to the shaft of the driven bevel gear 16. The screw is rotatably connected to the mounting frame 11. The driven bevel gear 16 is rotatably connected to the movable frame 5. The servo motor 14 drives the drive bevel gear 15 to rotate, which in turn drives the driven bevel gear 16 to rotate, thereby driving the screw to rotate and causing the mounting frame 11 to slide vertically, so as to adjust the height of the grinding wheel 13.

[0029] The working principle of this device is as follows:

[0030] In use, the bridge frame is transported to the loading position by the lifting platform 3, and then the cylinder 4 pushes the bridge frame into the grinding platform 2. The clamping cylinder 9 drives the clamping plate 10 to clamp and position the bridge frame. Then, the drive motor 7 drives the ball screw 6 to move the moving frame 5 to adjust the distance between the two grinding wheels 13. Then, the servo motor 14 drives the active bevel gear 15 to rotate, which in turn drives the driven bevel gear 16 to rotate, thereby driving the screw to rotate and causing the mounting frame 11 to slide vertically to move the grinding wheel 13 to the grinding position. The grinding motor 12 drives the grinding wheel 13 to rotate for grinding.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] The various modifications described in these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
