During the contact process, the extrusion panel slides along the piston. Since the piston is fixed to the limit panel through a movable rod, as the extrusion panel moves, the piston generates suction in the inner cavity of the extrudable panel. The suction cup can generate suction when the piston contacts the product. The suction generated by the piston can conveniently limit the product to prevent displacement during the processing and affect the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 7A multi-station transfer device for mechanical processing comprises a transfer platform 1 and a groove 2 provided on the upper end surface of the transfer platform 1, a plurality of U-shaped frames 3 are fixedly installed on the upper end of the transfer platform 1, a drilling assembly 4 is arranged on the plurality of U-shaped frames 3, a transfer assembly 5 for transferring mechanical parts and a limiting assembly 6 for clamping and limiting the mechanical parts are arranged on the groove 2, the transfer assembly 5 comprises a mounting groove 502 connected to the groove 2 and a conveyor belt 51 arranged on the mounting groove 502, the inner ring of the conveyor belt 51 is meshedly connected with a first gear 52, the first gear 52 is rotatably arranged on the groove 2, a connecting shaft 57 is fixedly installed at one end of the first gear 52, a second gear 56 is fixedly installed on the axial side wall of the connecting shaft 57, with the cooperation of the conveyor belt 51, the first gear 52, the second gear 56 and the limiting assembly 6, the mechanical parts to be processed can be automatically transferred to the next station, and the parts can be clamped and limited when they are processed.

[0032] The drilling assembly 4 includes a cylinder 41 fixedly mounted on the U-shaped frame 3 and a motor 42 fixedly mounted at the lower end of the cylinder 41. A drill bit 43 is provided at the output end of the motor 42, which can conveniently process the parts to be processed.

[0033] The transfer assembly 5 also includes a connecting panel 53 fixedly installed at the telescopic end of the cylinder 41 and a fixed panel 54 fixedly installed on the bottom wall of the connecting panel 53. Limiting panels 55 are fixedly installed at both ends of the fixed panel 54. The limiting panel 55 is provided with a plurality of limiting grooves 58. Trapezoidal blocks 501 are slidably arranged on the plurality of limiting grooves 58. The trapezoidal blocks 501 are meshed with the corresponding second gears 56. With the cooperation of the limiting panels 55, the limiting grooves 58, the trapezoidal blocks 501 and the second gears 56, after the mechanical parts are processed, the conveyor belt 51 can transfer the parts to the next workstation, which is convenient to operate.

[0034] It should be noted that: according to Figure 3 It can be seen that the inclined surfaces of the trapezoidal block 501 are set in opposite directions, so that the second gear 56 can be rotated separately during the descent and ascent processes, which is convenient for the product to be in a moving state before and after processing.

[0035] There are two second gears 56 and two limiting panels 55, and the inclined surfaces of the trapezoidal blocks 501 on the limiting panel 55 are arranged in opposite directions. Due to the inclined surface directions of the two trapezoidal blocks 501, when the limiting panel 55 is descending and ascending, the trapezoidal blocks 501 can drive the corresponding second gear 56 to rotate. Due to the sliding arrangement of the trapezoidal blocks 501, the limiting panel 55 can respectively drive the second gears 56 during the process of descending and ascending, and the two second gears 56 will not repel each other in motion.

[0036] A first spring 59 is fixedly connected between the trapezoidal block 501 and the limiting groove 58. Through the arrangement of the first spring 59, the trapezoidal block 501 can be easily restored to its initial state after being squeezed.

[0037] In this embodiment, the product to be processed is first placed on the first conveyor belt 51, and then the cylinder 41 is turned on. The cylinder 41 drives the motor 42 and the drill bit 43 to move close to the product to be processed. During the movement, the cylinder 41 drives the fixed panel 54 to move downward through the connecting panel 53. During the downward displacement of the fixed panel 54, it will drive the two limiting panels 55 at both ends to move downward. The inclined surfaces of the trapezoidal blocks 501 on the two limiting panels 55 are in opposite directions. When one of them contacts the second gear 56, the trapezoidal block 501 will be squeezed by the tooth block of the second gear 56 and retracted into the limiting groove 58, and will not drive it to rotate. The other set of trapezoidal blocks 501 will drive the second gear 56 to rotate, and the second gear 56 drives the conveyor belt 51 to rotate through the first gear 52. With the transmission of the conveyor belt 51, the product to be processed can be transmitted to the bottom of the drill bit 43. After processing, the fixed panel 54 moves up, and one set of trapezoidal blocks 501 will drive the conveyor belt 51 to rotate, so that the processed product can be transmitted to the next one.

[0038] Reference Figure 2 , a transfer component 7 is provided on the transfer platform 1;

[0039] The transfer assembly 7 includes a movable groove 71 opened on the groove 2 and an electric wheel 72 rotatably arranged on the movable groove 71. The electric wheel 72 is arranged on one side of the conveyor belt 51. Through the arrangement of the electric wheel 72, the mechanical parts can be better transmitted after processing.

[0040] A set of transfer components 7 is arranged between each workstation, so that position transfer can be performed more quickly and conveniently.

[0041] In this embodiment, when the processed product is transferred by the conveyor belt 51, one end of the product will slide onto the electric wheel 72. Through the setting of the electric wheel 72, the processed product can be better and more conveniently transferred to the next workstation. A group of transfer components 7 are arranged between each workstation, which can perform position transfer more quickly and conveniently.

[0042] Reference Figure 3-7 The limiting assembly 6 includes an extrusion panel 61 slidably arranged on the groove 2 and a suction cup 62 connected to the extrusion panel 61. A piston 63 is slidably arranged on the inner cavity of the extrusion panel 61. The setting of the piston 63 and the extrusion panel 61 can limit the clamping of the mechanical parts to be processed. When the processing is completed, the clamping of the mechanical parts can be automatically released.

[0043] A limit panel 65 is fixedly installed on the upper end of the groove 2, and a movable rod 64 is fixedly installed on the side wall of the limit panel 65. The movable rod 64 is slidably set on the extrusion panel 61, and one end of the movable rod 64 is fixedly connected to the piston 63. A movable shaft 66 is slidably set on the side wall of the limit panel 65, and one end of the movable shaft 66 is fixedly connected to the side wall of the extrusion panel 61. The movable shaft 66 is slidably set on the groove 2, and one end of the movable shaft 66 is fixedly installed with a first triangular block 68. A second triangular block 69 is fixedly installed on the side wall of the fixed panel 54, and the second triangular block 69 is fitted with the inclined surface of the first triangular block 68. A second spring 67 is sleeved on the movable shaft 66, and the two ends of the second spring 67 are respectively fixedly connected to the axial side wall of the movable shaft 66 and the side wall of the limit panel 65. When drilling the mechanical parts, the first triangular block 68 and the second triangular block 69 cooperate, and the extrusion panel 61 can clamp the mechanical parts for easy later operation.

[0044] In this embodiment, when the fixed panel 54 moves downward, it will squeeze the first triangular block 68 through the second triangular block 69. Since the inclined surfaces of the two are in contact with each other, the second triangular block 69 can conveniently squeeze the first triangular block 68. The first triangular block 68 can drive the movable shaft 66 to slide along the movable shaft 66. The movable shaft 66 will move the extrusion panel 61 close to the product to be processed until it contacts it. During the contact process, the extrusion panel 61 slides along the piston 63. Since the piston 63 is fixed to the limiting panel 65 through the movable rod 64, as the extrusion panel 61 moves, the piston 63 generates suction in the inner cavity of the extrudable panel 61. The suction cup 62 can generate suction. When the piston 63 contacts the product, the suction generated by it can conveniently limit the product to prevent it from shifting during the processing and affecting the processing efficiency.

[0045] Therefore, with the cooperation of the cylinder 41, the motor 42 and the drill bit 43, the product can be processed conveniently. At the same time, with the cooperation of the cylinder 41, the connecting panel 53, the fixed panel 54, the limiting panel 55, the trapezoidal block 501, the second gear 56 and the limiting groove 58, a group of trapezoidal blocks 501 will drive the second gear 56 to rotate, and the second gear 56 drives the conveyor belt 51 to rotate through the first gear 52. With the transmission of the conveyor belt 51, the product to be processed can be transmitted to the bottom of the drill bit 43. After the processing is completed, the fixed panel 54 moves up, and one group of trapezoidal blocks 501 will drive the conveyor belt 51 to rotate, so that the processed product can be transmitted to the next workstation. One end of the product will slide onto the electric wheel 72. Through the setting of the electric wheel 72, the processed product can be better and more conveniently transmitted to the next workstation. A group of transfer components is set between each workstation. 7. It can transfer the position more quickly and conveniently. When the fixed panel 54 moves downward, it will squeeze the first triangular block 68 through the second triangular block 69. Because the inclined surfaces of the two are in contact, the second triangular block 69 can conveniently squeeze the first triangular block 68. The first triangular block 68 can drive the movable shaft 66 to slide along the movable shaft 66. The movable shaft 66 will move the extrusion panel 61 close to the product to be processed until it contacts it. During the contact process, the extrusion panel 61 slides along the piston 63. Since the piston 63 is fixed on the limiting panel 65 through the movable rod 64, as the extrusion panel 61 moves, the piston 63 generates suction in the inner cavity of the extrudable panel 61. Through the setting of the suction cup 62, it can generate suction. When the piston 63 contacts the product, the suction generated by it can conveniently limit the product to prevent it from shifting during the processing.
