when the feeding slide block 19 pushes the part 21 to be processed to the drilling processing station, the main shaft 11 drives the positioning cam 25 of the positioning mechanism to rotate through the second belt pulley transmission system 8, the positioning cam 25 pushes the positioning connecting rod 27 to move along the fixing hole of the positioning connecting rod supporting frame 28 through the positioning cam roller 26, so that the positioning rod 31 connected to the end part of the positioning connecting rod 27 is pushed to move along the positioning hole 59 formed in the workbench 20, the positioning function is realized, and the feeding slide block 19 can accurately push the part 21 to be processed to the drilling processing station of the workbench. Meanwhile, in the positioning process, the first spring 29 arranged between the positioning link support 28 and the positioning link 27 is stretched, and when the positioning cam 25 returns, the first spring 29 pulls the positioning link 27 to realize the return function.
After the part 21 to be machined is accurately pushed to the drilling machining station, the feeding mechanism returns immediately, the main shaft 11 drives the clamping cam 35 of the clamping mechanism to rotate through the fourth belt wheel transmission system 4, the clamping cam 35 pushes the clamping connecting rod 32 to move along the fixing hole of the clamping connecting rod supporting frame 34 through the clamping cam roller 36, the clamp 39 fixedly connected with the top end of the clamping connecting rod 32 moves along the bottom surface of the workbench under the pushing action of the clamping connecting rod 32, the workpiece 21 to be machined is clamped when the clamping cam 35 reaches a far rest state, continuous clamping is realized by means of the pressure maintaining characteristic of the cam, meanwhile, in the clamping process, the second spring arranged between the middle part of the clamping connecting rod and the clamping connecting rod supporting frame is stretched, and when the clamping cam 35 returns, the second spring 33 pulls the clamping connecting rod 32 to realize the return function.
After the clamp 39 reaches the designated position, the positioning cam 25 drives the drilling cam 51 of the drilling mechanism to rotate through the third belt wheel transmission system 7, the middle fixing hole of the L-shaped connecting rod 41 is in clearance fit with the rotating shaft on the drilling mechanism baffle 52, the drilling cam 51 pushes the L-shaped connecting rod 41 to rotate around the rotating shaft on the drilling mechanism baffle 52 through the drilling cam roller, the L-shaped connecting rod 41 drives the drilling swing rod 43 to rotate, so as to drive the large tooth profile connecting rod 50 to rotate around the rotating shaft on the drilling mechanism baffle 52, the large tooth profile 49 arranged at one end of the large tooth profile connecting rod 50 is in meshing transmission with the gear rack mechanism 48, the gear rack mechanism 48 drives the power head 46 welded on the rack 47 to move up and down, and the cutter 45 arranged at the bottom of the power head 46 moves up and down along with the power head. In addition, the third spring 42 connected between one end of the L-shaped link 41 and the boss of the drilling mechanism baffle 52 is stretched in the process of rotation of the L-shaped link 41, the tension of the third spring 42 enables the drilling cam roller 40 to be always in contact with the drilling cam 51, and the rack positioning rod 44 is in clearance fit with the fixed hole in the rack 47 and used for preventing the rack 47 from moving in the drilling process and affecting the drilling precision.
After the part to be processed is processed, the drilling mechanism firstly returns, then the positioning mechanism returns, finally the clamping mechanism returns, the discharging mechanism utilizes the return of the clamping mechanism to discharge materials, when the clamping cam 35 enters a pushing process, namely the clamp 39 gradually approaches the workpiece 21 to be processed, the part 21 to be processed abuts against the discharging swing rod 58 so as to enable the discharging swing rod 58 to rotate, the discharging swing rod 58 drives the discharging connecting rod 57 to rotate so as to enable the discharging sliding block 53 to move along the guide column 55, the reset spring 56 sleeved on the guide column is compressed in the process, when the clamping mechanism clamps the workpiece (the clamping cam 35 reaches a far stop), the reset spring 56 releases elastic potential energy to enable the discharging swing rod 58 to return, and when the clamping mechanism returns, the discharging swing rod 58 pulls the processed workpiece 21 into the discharging chute 22 to realize an automatic discharging function.
