[0002] Parts processing is a process of converting raw materials into finished parts. It is one of the important links in the manufacturing industry. Parts processing involves steps such as cutting, milling and drilling. Drilling is a very important step in parts processing. In order to better assemble the corresponding machinery and machines, it is necessary to process some matching structures such as slots and holes on the corresponding parts so that the corresponding parts can achieve corresponding perfect matching. During the drilling process, the workpiece needs to be fixed on the operating platform to ensure the drilling accuracy of the workpiece.

[0003] Different fixing methods are required for parts with different shapes and hole position requirements. When drilling flat parts with a large number of holes, workers are required to hold the parts and place them on the workbench.

Anti-skid pads 6 are installed at the four corners of the bottom of the workbench 1. The anti-skid pads 6 can increase the friction between the workbench 1 and the ground to prevent the workbench 1 from shifting during the punching process. A clamping mechanism 3 for clamping and fixing parts is provided on the workbench 1, and an adjusting mechanism 5 for adjusting the punching position of parts is provided in the workbench 1. The clamping mechanism 3 includes a placement plate 31, an adjusting block 33, a clamping block 34, a spring A placing plate 31 is rotatably connected to the top of the workbench 1. Through holes 32 are evenly spaced along the circumference of the placing plate 31. Four guide grooves 36 are evenly spaced along the circumference of the placing plate 31. A slide rod 37 is slidably connected in the guide groove 36. An adjusting block 33 is connected to the slide rod 37. The adjusting block 33 is slidably connected to the placing plate 31. Two guide rods are slidably connected to the adjusting block 33. A clamping block 34 is connected between the two guide rods. The clamping block 34 is provided with anti-slip grooves on the side close to the parts, which can increase the friction between the clamping block 34 and the parts, so that the parts are clamped more firmly on the placing plate 31. The clamping block 34 is slidably connected to the placing plate 31. A spring 35 is sleeved on the guide rod. The spring 35 is connected to the adjusting block 33 and the clamping The adjusting mechanism 5 comprises an adjusting disk 51, a connecting block 53, a motor 54, a rotating disk 55, a threaded rod 56, a limiting plate 57 and a connecting ring 58. The motor 54 is installed at the lower part of the workbench 1. The output shaft of the motor 54 is connected with the rotating disk 55. The rotating disk 55 is located in the workbench 1. The rotating disk 55 is slidably connected to the workbench 1. Two connecting blocks 53 are symmetrically installed on the top of the rotating disk 55 along the circumferential direction. The connecting block 53 is fixedly connected to the placement disk 31. A connecting ring 58 is installed between the two connecting blocks 53. The adjusting disk 51 is rotatably connected in the connecting ring 58. The adjusting disk 51 is located between the placement disk 31 and the rotating disk 55. Four adjusting inclined grooves 52 are evenly spaced along the circumferential direction on the adjusting disk 51. The four sliding rods 37 are respectively located in the four adjusting inclined grooves 52. When the adjusting disk 51 rotates, the four sliding rods 37 are squeezed close to each other through the adjusting inclined groove 52. The adjusting disk 51 is connected with a threaded rod 56, and the threaded rod 56 is threadedly connected with a limit plate 57. The limit plate 57 is slidably connected with the connecting block 53. The right side of the workbench 1 is designed as an opening. The rotation of the threaded rod 56 can be conveniently controlled through the opening on the right side of the workbench 1. It also includes a pressing mechanism 4, which includes a mounting block 41, a connecting plate 42, a second spring 43, a third spring 44, a pressing plate 45 and a connecting sleeve 46. A mounting block 41 is installed on the top of the placement disk 31, and a connecting sleeve 46 is connected to the mounting block 41. A guide rod is connected inside the connecting sleeve 46, and a spring second 43 is sleeved on the guide rod of the connecting sleeve 46. The connecting plate 42 is slidably connected to the guide rod of the connecting sleeve 46.The second spring 43 is connected to the connecting plate 42 and the connecting sleeve 46. The connecting plate 42 is slidably connected with a sliding rod, and the lower part of the sliding rod is connected with a pressing plate 45. The sliding rod is sleeved with a third spring 44, and the third spring 44 is connected to the connecting plate 42 and the pressing plate 45.

[0020] The parts are placed on the placement plate 31, and then the threaded rod 56 is manually controlled to rotate forward to drive the adjusting plate 51 to rotate forward. Under the guidance of the adjusting inclined slot 52, the sliding rod 37 will slide in the direction close to the threaded rod 56, thereby driving the adjusting block 33, the spring 1 35 and the clamping block 34 to move in the direction close to the parts. When the clamping block 34 touches the parts, it stops moving. At this time, the spring 1 35 is gradually compressed, so that the parts can be clamped. In this process, the limit plate 57 will move upward with the rotation of the threaded rod 56. When the threaded rod 56 stops rotating, the threaded rod 56 can be locked through the limit plate 57 to prevent the threaded rod 56 and the adjusting plate 51 from rotating. Then, the piston rod of the hydraulic cylinder 21 is controlled to extend to drive the movable plate 22 and the drill bit 23 to move downward. When the movable plate 22 touches the connecting plate 42, it will drive the pressing plate 45 to move downward. At this time, the spring 2 43 is compressed. When the pressing plate 45 touches the parts, it will rebound. The spring 44 is gradually compressed, so that the parts can be fixed on the placement plate 31. As the drill bit 23 moves downward, the parts will be punched. The through hole 32 on the placement plate 31 can prevent the drill bit 23 from contacting the placement plate 31, thereby causing damage to the placement plate 31. After the processing of the current hole position of the part is completed, the piston rod of the hydraulic cylinder 21 is controlled to retract and drive the movable plate 22 and the drill bit 23 to reset upward to the initial position. Then the motor 54 is controlled to drive the turntable 55, the connecting block 53 and the placement plate 31 to rotate, thereby driving the parts on the placement plate 31 to rotate, so that the function of adjusting the punching position of the parts can be realized. At the same time, the limit plate 57, the threaded rod 56 and the adjustment plate 51 will rotate synchronously. When the placement plate 31 drives the parts to rotate to the next punching position, the above operation is repeated. In this way, multiple positions on the parts can be punched without manually holding the parts.
