[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1

[0024] Reference Figure 1 , Figure 2The present invention provides an automatic loading device for pulley production, comprising a transfer trolley 2 and a loading platform 1. The transfer trolley 2 is provided with a top plate 201, on which a pulley bracket 3 is mounted, and the pulley bracket 3 includes a rotatable tray 301, on which a C-shaped base 302 is arranged in a circular array, and on which a plurality of positioning support columns 303 are vertically mounted. In actual application, the positioning support columns 303 and the through holes on the pulley 10 are of the same number and arrangement, and the pulley 10 is sleeved on the positioning support columns 303. A material distribution trough 304 connected to the C-shaped base is also provided on the tray 301.

[0025] A lifting shaft 305 and a plurality of positioning pins 307 are installed at the bottom of the pallet 301. The lower end of the lifting shaft 305 passes through the top plate 201 and is equipped with a driven gear 306. A positioning hole matching the positioning pin 307 is opened on the top plate 201. During transportation, the positioning pin 307 is inserted into the positioning hole, so that the pulley 10 mounted on the pallet 301 and the positioning support column 303 remains stable during transportation.

[0026] A material distribution rack 6 is installed on the loading platform 1, a double-axis displacement mechanism 8 is installed on the top of the material distribution rack 6, a material distribution mechanism 9 is installed on the double-axis displacement mechanism 8, a vertical screw 601 and a guide rod 604 are installed on the material distribution rack 6, a lifting plate 602 is provided on the screw 601 and is threadedly matched with the lifting plate 602, the guide rod 604 passes through the lifting plate 602, a lifting plate 603 is provided on the lifting plate 602, and the lifting plate 603 is matched with the material distribution trough 304. A lifting motor 7 is installed on the loading platform 1 below the material distribution rack 6, and the output shaft of the lifting motor 7 is connected to the screw 601 to drive the lifting plate 603 to move vertically on the material distribution rack 6.

[0027] A lifting cylinder 4 and a rotating motor 5 are provided between the material distribution rack 6 and the transfer trolley 2, wherein the rotating motor 5 is provided between the lifting cylinder 4 and the material distribution rack 6, a support plate 401 is rotatably connected to the top of the lifting cylinder 4, and a driving gear 501 is installed on the output shaft of the rotating motor 5;

[0028] When loading, the transfer trolley 2 moves toward the material distribution frame 6, so that the lifting plate 603 is inserted into the material distribution trough 304. At this time, the lifting cylinder 4 is coaxial with the lifting shaft 305, and the driven gear 306 is below the driving gear 501. The lifting motor 7 drives the lifting plate 603 to rise, thereby lifting the pulley 10 on the positioning support column 303 upward. When the pulley 10 at the uppermost end is separated from the positioning support column 303, the feeding mechanism 9 grabs it and transfers it to the processing equipment by the dual-axis displacement mechanism 8; when the pulley 10 on a positioning support column 303 is transferred, the lifting plate 603 is reset to the lowermost end, and the piston rod of the lifting cylinder 4 extends to lift the tray 301, and the positioning pin 30 7 is disengaged from the positioning hole, at which time the driven gear 306 meshes with the driving gear 501, thereby driving the tray 301 to rotate, so that the next material distribution trough 304 is opposite to the lifting plate 603; in actual application, the teeth of the driven gear 306 and the driving gear 501 may be opposite to each other and cannot mesh, and another transmission scheme is proposed here: friction transmission is adopted between the two, that is, elastic friction material is set on the outer rings of the two, and when the driven gear 306 rises, it is pressed against the outer ring of the driving gear 501 to realize transmission, and at the same time, a locking and unlocking mechanism is set between the transfer trolley 2 and the loading platform 1, which connects the transfer trolley 2 with the loading platform 1 to maintain stability during transmission and in the loading process.

[0029] Embodiment 2,

[0030] Based on Example 1, Figure 3 , Figure 4 The dual-axis displacement mechanism 8 is mainly composed of a translation support rod 801 and a lifting support rod 802, forming a system that can perform precise movement in the X-axis and Y-axis directions. A slidable slide 803 is installed on the translation support rod 801, and the lifting support rod 802 is slidably connected to the slide 803. A translation rack 804 and a lifting rack 806 are respectively installed on the translation support rod 801 and the lifting support rod 802. A translation motor 805 and a lifting motor 807 that are respectively engaged with the translation rack 804 and the lifting rack 806 are installed on the slide 803. The movement of the translation support rod 801 and the lifting support rod 802 are respectively controlled by the translation motor 805 and the lifting motor 807.

[0031] The feeding mechanism 9 includes a feed support plate 901, on which a slidable connecting seat 902 is provided for connecting the lower end of the lifting support rod 802. The feed support plate 901 and the translation support rod 801 are arranged vertically in the horizontal direction. A feed cylinder 903 is installed on one side of the feed support plate 901, and its piston rod is connected to one end of the feed support plate 901. The cylinder body is connected to the connecting seat 902 for controlling the movement of the feed support plate 901 in the Z-axis direction.

[0032] A feeding cylinder 904 is installed below the feeding mechanism 9. The piston rod of the feeding cylinder 904 is perpendicular to the feed cylinder 903 and is used to install or remove the pulley 10 on the chuck of the processing equipment during feeding. An oblique support plate 905 is installed below the feeding cylinder 904. The oblique support plate 905 is connected to the piston rod of the feeding cylinder 904. The oblique support plate 905 forms an angle of 45° with the vertical direction. A rotating cylinder 906 is provided on the upper surface of the oblique support plate 905, and a clamping jaw bracket 907 is provided on the lower surface. The clamping jaw bracket 907 is connected to the rotating shaft of the rotating cylinder 906. Two mutually perpendicular mounting surfaces are provided on the clamping jaw bracket 907 with the rotating shaft of the rotating cylinder 906 as the center. The clamping jaw cylinder 908 is provided on both mounting surfaces. In this way, when the rotating cylinder 906 drives the clamping jaw bracket 907 to rotate, the clamping jaw cylinder 908 can switch between a vertical state and a horizontal state.

[0033] Before loading, the vertical clamping cylinder 908 grabs the pulley 10 from the transfer trolley 2, and is moved to the processing equipment by the double-axis displacement mechanism 8. The idle clamping cylinder 908 is in a horizontal state to remove the processed pulley 10 on the chuck of the processing equipment, and the rotating cylinder 906 drives the clamping bracket 907 to rotate to make the other clamping cylinder 908 turn to a horizontal state, and with the cooperation of the feeding cylinder 904, the unprocessed pulley 10 is sent to the chuck of the processing equipment, and the processed pulley 10 is sent to the next processing equipment or transfer equipment by the double-axis displacement mechanism 8. This reciprocating cycle realizes automatic loading and unloading of the pulley 10, effectively improving production efficiency.

[0034] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
