[0002] In the machinery manufacturing industry, the processing and production of parts typically involves multiple core processes such as drilling, tapping, and milling. Currently, ordinary machine tools are still widely used in actual production to complete these processing operations. However, the complete processing of a single workpiece requires different processes to be completed sequentially on different ordinary machine tools, which leads to frequent changes of equipment in the processing flow.

[0003] Frequent changes in equipment not only consume a lot of time and severely reduce overall production efficiency, making it impossible to meet the high-efficiency processing needs of large batches of parts; at the same time, multiple processes require multiple ordinary machine tools, which require a larger area, and each machine usually requires at least one operator, requiring more manpower and significantly increasing the company's labor costs, which is not conducive to the company controlling production costs and improving market competitiveness.

[0004] Based on this, a multi-station rotary automatic feeding device for drilling and tapping centers is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5 As shown, the multi-station rotary automatic feeding device for drilling and tapping centers includes a work platform 100, a controller 103, a fixed column 101 fixedly connected to the upper end of the work platform 100, a rotating disk 102 rotatably connected to the upper end of the fixed column 101, multiple clamping mechanisms for fixing workpieces on the rotating disk 102, an intermittent rotating component fixedly connected to the lower end of the rotating disk 102, an automatic feeding component on the work platform 100, and an automatic unloading component on the fixed column 101. The module uses an automatic feeding component to feed the workpiece, a clamping mechanism to hold the workpiece, and an intermittent rotating component to drive the workpiece to rotate intermittently, so that the workpiece is moved to different workstations for drilling, tapping, chamfering and other processes. After the process is completed, the clamping mechanism releases the workpiece, and the automatic unloading module pushes the workpiece out to complete the unloading, which greatly reduces the auxiliary processing time. The controller 103 adopts a PLC controller, which is electrically connected to the intermittent rotating component, the automatic feeding component, the automatic unloading module and the clamping mechanism to control the coordinated operation of each component.

[0023] In this embodiment, as Figure 3 As shown, the clamping mechanism includes a clamping base 201, on which a telescopic rod 202 is fixedly connected. The output rod of the telescopic rod 202 is fixedly connected to a moving plate 203. The moving plate 203 is slidably connected to a corresponding moving groove 207 on the clamping base 201. The moving plate 203 has two symmetrical inclined grooves 204, in which a moving rod 205 is slidably connected. The moving rod 205 is fixedly connected to a clamping block 206, and the clamping block 206 is slidably connected to the clamping base 201. When it is necessary to clamp the workpiece, the telescopic rod 202 extends its output rod, causing the moving plate 203 to slide within the moving groove 207. The inclined grooves 204 on the moving plate 203 cause the two moving rods 205 to move closer to each other, and the moving rods 205 cause the two clamping blocks 206 to move closer to each other, thus clamping the workpiece.

[0024] In one embodiment, such as Figure 5 As shown, the automatic feeding component includes a fixed frame 301, which is fixedly connected to the work platform 100. A conveyor belt 302 is fixedly connected to the fixed frame 301. A movable frame 303 is provided on the fixed frame 301 and is fixedly connected to the fixed frame 301. The movable frame 303 has an inlet 304 and an outlet 305. The inlet 304 corresponds to the position of the conveyor belt 302, and the outlet 305 corresponds to the position of the clamping seat 201. A movable block 306 is slidably connected in the movable frame 303. The movable block 306 is driven by a telescopic rod 307, which is fixedly connected to the movable frame. On the 303, the moving block 306 is provided with a placement slot, and the moving frame 303 is slidably connected to the push block 308. The push block 308 is driven by the telescopic rod 309, which is fixedly connected to the moving frame 303. The workpiece to be processed is placed on the conveyor belt 302. The workpiece moves with the conveyor belt 302 and moves from the feed port 304 to the placement slot on the moving block 306. Only one workpiece can be placed in the placement slot at a time. The telescopic rod 307 extends out as an output rod, driving the moving block 306 to the discharge port 305. The telescopic rod 309 drives the push block 308 to move and push the workpiece from the discharge port 305 to the clamping seat 201 for clamping.

[0025] In one embodiment, such as Figure 2 and Figure 3As shown, the automatic unloading module includes a telescopic rod 401, which is fixedly connected to the fixed column 101. The output rod of the telescopic rod 401 is fixedly connected to the push block 402. The clamping seat 201 is slidably connected to the push rod 403. One end of the push rod 403 is fixedly connected to the stop block 404, which corresponds to the position of the push block 402. The outer end of the push rod 403 is provided with a spring 405. The two ends of the spring 405 are respectively connected to the stop block 404 and the clamping seat 201. When the processed workpiece rotates to the unloading position with the rotating disk 102, the telescopic rod 202 retracts, the clamping blocks 206 move away from each other, and the workpiece is released. At the same time, the telescopic rod 401 extends its output rod, which drives the push block 402 to push the stop block 404. The stop block 404 drives the push rod 403 to move and compresses the spring 405. The push rod 403 pushes the workpiece out of the clamping seat 201.

[0026] In one embodiment, such as Figure 4 As shown, the intermittent rotating component includes a grooved wheel 501, which is fixedly connected to the lower end of the rotating disk 102. The grooved wheel 501 has multiple limiting grooves 502, and each limiting groove 502 contains a limiting rod 503. The limiting rod 503 is fixedly connected to a rotating disk 504. The rotating disk 504 is driven by a stepper motor 505, which is fixedly connected to the work platform 100. The stepper motor 505 drives the rotating disk 504 to rotate, and the limiting rod 503 on the rotating disk 504 enters the limiting groove 502 of the grooved wheel 501, causing the grooved wheel 501 to rotate synchronously with the rotating disk 102. This causes the clamping mechanism holding the workpiece to rotate to the drilling position. After the drilling equipment completes the drilling process on the workpiece, the rotating disk continues to rotate, sequentially transporting the workpiece to different processing positions to complete the corresponding processing steps.

[0027] In one embodiment, such as Figure 5 As shown, the movable frame 303 is equipped with a photoelectric sensor 600, which detects whether the workpiece has fallen into the placement slot of the movable block 306.

[0028] In one embodiment, such as Figure 2 and Figure 4 As shown, the number of limiting grooves 502 corresponds to the number of clamping mechanisms, so that the angle at which the rotating disk drives the clamping mechanism each time corresponds to the position of the processing station.

[0029] In one embodiment, such as Figure 3 As shown, the clamping block 206 is provided with a rubber pad 700 to increase the friction force when clamping the workpiece and ensure the stability of the workpiece clamping.

[0030] The above embodiment discloses a multi-station rotary automatic feeding device for drilling and tapping centers. The workpiece to be processed is placed on a conveyor belt 302. As the conveyor belt 302 moves, the workpiece moves from the inlet 304 to a placement slot on the moving block 306. Only one workpiece can be placed in the placement slot at a time. When the photoelectric sensor 600 detects that a workpiece has fallen into the placement slot of the moving block 306, the controller 103 controls the extension rod 207 to extend its output rod, moving the moving block 306 to the outlet 305. The extension rod 309 moves the push block 308, pushing the workpiece out of the outlet 305 and onto the clamping seat 201. The extension rod 202 extends its output rod, causing the moving plate 203 to slide within the moving slot 207. The inclined groove 204 on the moving plate 203 drives the two moving rods 205 to move together. As the two clamping blocks 206 move closer together, the moving rod 205 moves them closer together to clamp the workpiece. The stepper motor 505 drives the rotating disk 504 to rotate. The limiting rod 503 on the rotating disk 504 enters the limiting groove 502 of the grooved wheel 501, causing the grooved wheel 501 to rotate synchronously with the rotating disk 102. This causes the clamping mechanism with the workpiece to rotate to different processing positions in sequence to complete the corresponding processing steps. When the processed workpiece rotates to the unloading position with the rotating disk 102, the telescopic rod 1 202 retracts, the clamping blocks 206 move away from each other, and the workpiece is released. At the same time, the telescopic rod 401 extends the output rod, which drives the push block 2 402 to push the stop block 404. The stop block 404 drives the push rod 403 to move and compress the spring 405. The push rod 403 pushes the workpiece out of the clamping seat 201.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
