DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1—5. A hole-expanding device for processing aluminum alloy automobile parts, comprising a conveying device, a clamping and positioning mechanism, and a hole-expanding mechanism, wherein the conveying device is used to convey the parts, so that the parts can be automatically loaded and unloaded. Specifically, the conveying device comprises a conveying frame 101 and a conveyor belt mechanism 102 arranged on the conveying frame 101. A detection sensor is fixedly connected to the conveying frame 101, that is, the parts are conveyed by the conveyor belt of the conveyor belt mechanism 102, and the conveying position is detected by the detection sensor. The detection sensor here can be a laser sensor;

[0022] Furthermore, a clamping and positioning mechanism for clamping and positioning spare parts is fixedly connected to the conveying device, and the clamping and positioning mechanism is matched with the detection sensor. Specifically, the clamping and positioning mechanism includes two sets of clamping tables 201 and a traction module 202 for controlling the movement of the two sets of clamping tables 201. To further explain, the traction module 202 includes a mounting frame 203, a first lead screw 204, a second lead screw 205, a traction table 206 and a servo motor 207. The mounting frame 203 is fixedly connected to the conveying frame 101, and a sliding column 208 is fixedly connected to the mounting frame 203. Two sets of traction tables 206 are slidably connected to the sliding column 208, and the two sets of traction tables 206 are respectively located on both sides of the conveyor belt mechanism 102. Each set of traction tables 206 is fixedly connected to the clamping table 201, one set of traction tables 206 is threadedly connected to the first lead screw 204, and the other set of traction tables 206 is threadedly connected to the second lead screw 20 5. The first lead screw 204 and the second lead screw 205 are fixedly connected by a transmission shaft 209, and a servo motor 207 is fixedly connected to the mounting frame 203. The servo motor 207 is connected to the first lead screw 204 or the second lead screw 205 by power, so that the servo motor 207 can drive the first lead screw 204 and the second lead screw 205 to rotate synchronously, so that the two groups of traction tables 206 drive the clamping tables 201 to move closer to or away from each other. When the two groups of clamping tables 201 move closer to each other, the parts on the conveyor belt mechanism 102 can be clamped, and the two groups of clamping tables 201 are provided with clamping grooves 2011 that match the contours of the parts to be processed. In this way, under the setting of the clamping grooves 2011, the two groups of clamping tables 201 can push the parts to be completely embedded in the clamping grooves 2011 to achieve positioning. Even when the conveyor belt mechanism 102 transports the parts with slight deviations, the parts can be accurately positioned.

[0023] In addition, a hole-expanding mechanism for expanding holes in spare parts is fixedly connected to the corresponding clamping and positioning mechanism on the conveying device. Specifically, the hole-expanding mechanism includes a lifting module 301 and a hole-expanding drill 302 arranged on the lifting module 301. A driving motor 303 for driving the hole-expanding drill 302 to rotate is also provided on the lifting module 301. The hole-expanding drill 302 corresponds to the hole-expanding part of the spare part to be processed. It is further described that the lifting module 301 includes a lifting frame 304, a servo lifting cylinder 305, a lifting platform 306 and a guide column 307. The lifting frame is fixedly connected to the mounting frame 203, the lifting frame is fixedly connected to the guide column 307, and the guide column 307 is slidably connected to the lifting platform 306. 06. A servo lifting cylinder 305 is fixedly connected to the lifting frame 304. The piston end of the servo lifting cylinder 305 is fixedly connected to the lifting platform 306. A drill bit mounting cylinder 308 is rotatably connected to the lifting platform 306. The drill bit mounting cylinder 308 is fixedly connected to the reaming drill bit 302. A driving motor 303 is fixedly connected to the lifting platform 306. The driving motor 303 is connected to the drill bit mounting cylinder 308 by power. In this way, the lifting platform 306 can be driven to rise and fall by the servo lifting cylinder 305. When the lifting platform 306 descends, the reaming drill bit 302 can be driven to descend. At this time, the driving motor 303 drives the reaming drill bit 302 to rotate, so that the reaming drill bit 302 can reame holes on the parts that have been positioned.

[0024] Furthermore, there are multiple groups of drill bit installation tubes 308, each group of drill bit installation tubes 308 is fixedly connected with a hole expansion drill 302, each group of hole expansion drill 302 corresponds to a group of hole expansion positions of the spare parts to be processed, and the multiple groups of drill bit installation tubes 308 are respectively connected by power through transmission members 309, and the driving motor 303 is connected to one group of drill bit installation tubes 308. In this way, multiple groups of required hole positions can be expanded on the spare parts at one time, reducing subsequent processing and thus improving efficiency. The above-mentioned transmission member 309 can be a combination of a synchronous belt and a synchronous wheel, and drills at different positions can use drills of different sizes according to needs;

[0025] In order to realize the automatic operation, a PLC controller is also included. The detection sensor, the motor in the conveyor belt mechanism, the servo motor 207, the drive motor 303 and the servo lifting cylinder 305 are connected to the PLC controller by signal connection. The specific connection method is an existing mature technology, so it is not repeated here. The following effects are achieved:

[0026] The spare parts are transported by a conveyor belt mechanism. When the detection sensor detects the spare parts, the PLC controller controls the conveyor belt mechanism to stop working. Then the PLC controller controls the servo motor 207 to work, so that the two sets of fixture tables 201 move closer to each other until the spare parts are clamped and positioned. Then the servo lifting cylinder 305 is controlled to descend, and the drive motor 303 is started at the same time. The reaming operation is performed on the spare parts by the rotating reaming drill bit 302. When the reaming is completed, the servo lifting cylinder 305 drives the reaming drill bit 302 to rise, and the servo motor 207 controls the two sets of fixture tables 201 to move away from each other. Finally, the conveyor belt mechanism outputs the processed spare parts. By continuously repeating the above work, the automatic reaming operation of the spare parts is realized.
