Description

Technical Field

[0001] The utility model relates to bolt processing, in particular to a loading and unloading mechanism for punching holes for flat head bolts. Background Art

[0002] A flat-head bolt is a type of bolt. The main difference from an ordinary bolt is that the original nut position is stamped into a flat shape, and a hole is drilled in this flat position. When using a flat-head bolt, a rod is inserted into the hole in the flat position, and the flat-head bolt can be easily rotated using the principle of leverage. Currently, drilling holes for flat-head bolts is generally completed using a punching machine, and the loading and unloading process is generally done manually. That is, the flat-head bolt is manually placed in the corresponding position on the punching machine, and then manually removed after the hole is drilled. Problems with manual loading and unloading include: high workload, safety hazards, and relatively low efficiency. Utility Model Content

[0035] See also Figure 1 、 Figure 2 and Figure 4 A loading and unloading mechanism for punching holes for flat head bolts includes an equipment frame 1, a mounting portion 2, a first cylinder 3, a material receiving guide rail 4, a material discharging guide rail 5, a slider 6, a second cylinder 7, a telescopic portion 8 and a driving mechanism 9.

[0036] The equipment frame 1 is equipped with flush loading and unloading stations and a punching station. For ease of explanation, the direction between the loading and punching stations is set as the first horizontal direction. The equipment frame 1 is equipped with a feed rail 1a at the position corresponding to the loading and unloading station. Specifically, the feed rail 1a can be inclined, with the lower end fixedly connected to the equipment frame 1. The processed flat head bolts fall along the feed rail 1a.

[0037] The mounting portion 2 is slidably connected to the equipment rack 1 and passes through the loading and unloading stations and the punching station. That is, the direction in which the mounting portion 2 slides back and forth is along the first horizontal direction. Specifically, a linear guide rail can be set between the mounting portion 2 and the equipment rack 1.

[0038] The first cylinder 3 drives the mounting portion 2 to slide. That is, the two travel limits of the first cylinder 3 just correspond to the loading and unloading station and the punching station respectively.

[0039] The receiving guide rail 4 and the discharging guide rail 5 are both fixedly connected to the mounting portion 2. When the mounting portion 2 is in the loading and unloading position, the feeding guide rail 1a is connected to the receiving guide rail 4. Specifically, the receiving guide rail 4 is used to receive the flat head bolts dropped from the feeding guide rail 1a. The mounting portion 2 slides, allowing the receiving guide rail 4, carrying the flat head bolts, to enter the punching position. The punching machine completes the drilling. The mounting portion 2 slides, allowing the receiving guide rail 4, carrying the punched flat head bolts, to return to the loading and unloading position. The punched flat head bolts are then discharged from the discharging guide rail 5.

[0040] See also Figure 1 The equipment frame 1 is equipped with a limit module 1b at the position corresponding to the punching station. When the material receiving guide rail 4 with the flat head bolts enters the punching station, the limit module 1b is used to limit the flat head bolts in the material receiving guide rail 4 in a second horizontal direction perpendicular to the first horizontal direction. Accordingly, the two side walls of the material receiving guide rail 4 are used to limit the flat head bolts in the first horizontal direction.

[0041] Optionally, the limiting module 1b comprises two baffles 1b1 fixedly connected to the equipment frame 1 along the second horizontal direction, achieving a limiting effect while maintaining a simple structure and low cost. Specifically, a gap is left between the feed guide 1a and the receiving guide 4, and between the receiving guide 4 and the discharge guide 5, to accommodate one of the baffles 1b1. When the mounting portion 2 is in the loading and unloading stations, the two baffles 1b1 and the flat-head bolts in the receiving guide 4 are staggered. After the receiving guide 4 enters the punching station, the two baffles 1b1 respectively block the two ends of the receiving guide 4, fitting into the two side walls of the receiving guide 4, surrounding the flat-head bolts on all sides to limit its position.

[0042] The slider 6 is connected to the mounting portion 2 in a sliding manner along the second horizontal direction. Specifically, a linear guide rail may be provided between the two.

[0043] See also Figure 2 and Figure 4 , the second cylinder 7 drives the slider 6 to slide. That is, the two stroke limits of the second cylinder 7 just correspond to the unloading position of the slider 6 close to the feed guide rail 1a and the loading position of the slider 6 away from the feed guide rail 1a.

[0044] See also Figure 3 and Figure 5The telescopic portion 8 is connected to the slider 6 by sliding up and down. Specifically, the slider 6 may have an optical axis, and the telescopic portion 8 is slidably connected to the optical axis. Accordingly, the mounting portion 2 and the material guide rail 4 are both provided with a through groove for the telescopic portion 8 to pass through and slide.

[0045] The driving mechanism 9 acts on the telescopic portion 8, i.e., controls the up and down sliding of the telescopic portion 8. When the mounting portion 2 is in the loading and unloading station, the telescopic portion 8 is in an extended state beyond the material receiving guide rail 4; when the mounting portion 2 is in the punching station, the telescopic portion 8 is in a retracted state within the material receiving guide rail 4.

[0046] In this way, when the mounting part 2 is at the loading and unloading station, the slider 6 is in the loading position and the telescopic part 8 is in the extended state; the flat head bolt falls from the feeding guide rail 1a to the receiving guide rail 4 until it rests against the telescopic part 8; the receiving guide rail 4 with the flat head bolt enters the punching station, the telescopic part 8 turns to the retracted state, and the slider 6 moves to the unloading position; after the punching is completed, the mounting part 2 returns to the loading and unloading station, the telescopic part 8 returns to the extended state, the slider 6 returns to the loading position and pushes the punched flat head bolt out of the discharging guide rail 5.

[0047] A cylinder can be used as a driving mechanism 9 to control the up and down sliding of the telescopic part 8. A linkage assembly can also be set between the first cylinder 3 and the telescopic part 8 as the driving mechanism 9, and the first cylinder 3 is used to drive the movement of the mounting part 2 and complete the movement of the telescopic part 8 at the same time. Compared with directly using a cylinder, the cost is lower and the debugging and control are more convenient. Furthermore, the driving mechanism 9 includes an elastic member 9a and a stopper 9b. The elastic member 9a is arranged between the telescopic part 8 and the slider 6, so that the telescopic part 8 is in an extended state. Specifically, the elastic member 9a can be a compression spring, which is sleeved on the optical axis of the slider 6; the stopper 9b is fixedly connected to the equipment frame 1, and the side close to the telescopic part 8 is an inclined surface for telescopic support. Accordingly, the telescopic part 8 is provided with a universal ball 8a on the end close to the stopper 9b.

[0048] Optionally, the discharge guide rail 5 is tubular. During the punching process, cooling liquid is used for flushing, and the tubular discharge guide rail 5 is more convenient for the flushing liquid to flow out.
