DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-9 , the present application provides a kind of technical scheme: a sleeve hanger processing vertical milling machine with lifting adjustment function, according to Figure 1 , Figure 2 , Figure 3 , Figure 7 And Figure 9As shown, the middle of the lower end of the processing platform 1 is provided with a support box 2, and the middle of the two sides of the processing platform 1 is symmetrically provided with a feeding through hole 101 and a discharging through hole 102 about the support box 2. The processing platform 1 is provided with a discharging guide frame 20 below the discharging through hole 102, and the inner side of the discharging guide frame 20 is connected with the side of the support box 2 close to the discharging through hole 102. At the same time, a ventilation mesh plate 201 is installed at the lower end of the back of the support box 2. Through the ventilation mesh plate 201, the gas entering the inside of the support box 2 is easily discharged. The front of the support box 2 is connected with a protective box door 202 through a hinge. By opening the protective box door 202, it is convenient to clean the impurities and debris stored in the inside of the support box 2. At the same time, the first conveying assembly 3 and the second conveying assembly 4 are respectively arranged above and below the feeding through hole 101 of the processing platform 1. The first conveying assembly 3 and the second conveying assembly 4 constitute a feeding mechanism. By using the first conveying assembly 3 and the second conveying assembly 4 in combination, it is convenient to automatically convey and feed the processing, improve the feeding efficiency, and reduce the labor output.

[0031] Specifically, the first conveying assembly 3 includes a conveying chassis 301. The lower end of the conveying chassis 301 is connected with one side of the upper end of the processing platform 1 through a plurality of support columns 302. A positioning hole 303 is formed in one side of the conveying chassis 301 above the feeding through hole 101. At the same time, a positioning frame 304 is arranged at the outer side of the lower end of the positioning hole 303. Through the positioning frame 304, the position of the conveying falling is more accurate. The inner sides of the positioning hole 303 and the positioning frame 304 are provided with an elastic rubber pad 305. Through the elastic rubber pad 305, when the workpiece is conveyed to the positioning hole 303, it has a certain resistance. Under the action of no external force, the workpiece cannot automatically fall and convey, improving the accuracy and timing of conveying, avoiding too fast conveying, causing the processing feeding not in time, and affecting the feeding efficiency. The upper end of the conveying chassis 301 is symmetrically provided with a conveying baffle 306. The side of the two conveying baffles 306 close to the positioning hole 303 is connected with a mounting frame 307. At the same time, the mounting frame 307 is an L-shaped structure.

Due to the inclination of one end of the conveying chassis 301, the workpieces are conveyed downward to above the positioning hole 303. Under the action of the elastic rubber pad 305, the workpieces are clamped in the positioning hole 303. Then the electric push rod 308 is started to push the pressing seat 309 downward. The pressing seat 309 pushes the workpieces to move downward in the positioning hole 303 until the workpieces pass through the positioning frame 304 and are connected with the second conveying assembly 4 arranged below, thereby completing the conveying of the workpieces.
