After the mechanical parts are processed in the smart factory, they need to be transferred to the subsequent processing preparation platform through the parts transfer vehicle. When the parts transfer vehicle is moving, the parts frame placed on the transfer vehicle may move on its surface and fall from above. When the transfer vehicle is bumped during movement, the center of gravity of the parts placed on the transfer vehicle is too high, which will cause the center of gravity of the parts placed on the transfer vehicle to be unstable when moving, resulting in a certain amount of sliding. Therefore, a fixed parts transfer vehicle is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] like Figure 1-6As shown, the utility model proposes a high-precision parts transfer vehicle for intelligent factories, comprising a transfer base plate 1, a plurality of universal wheels are evenly fixed on the lower end of the transfer base plate 1, a vertical fixed plate 2 is fixed on one side of the upper end of the transfer base plate 1, two storage components 4 for storing high-precision parts are arranged above the transfer base plate 1, and a lifting component 3 for adjusting the height of the storage component 4 is arranged inside the vertical fixed plate 2;

[0028] The lifting assembly 3 includes a lifting slot provided inside the vertical fixed plate 2, two guide rods 301 are symmetrically fixed inside the lifting slot, a sliding block 302 is slidably provided in the middle of the two guide rods 301, a lifting screw 303 is rotatably provided inside the lifting slot, an internal threaded hole is provided in the middle of the sliding block 302 for use with the lifting screw 303, a lifting motor 304 is fixedly provided in the middle of the upper end of the vertical fixed plate 2, and the output end of the lifting motor 304 is fixedly connected to the upper end of the lifting screw 303;

[0029] As can be seen from the above, the function of the lifting component 3 is to adjust the height of the two storage components 4. When the high-precision parts are processed and need to be transferred to the next process through the transfer vehicle, the lifting component 3 works, that is, the lifting motor 304 works, and the lifting motor 304 drives the lifting screw 303 to rotate, and the rotation of the lifting screw 303 can drive the sliding block 302 to move upward, and the sliding block 302 moves upward and then drives the four lateral guide blocks 401 to move upward, that is, drives the two storage components 4 to move upward; when the high-precision parts are stored in the storage transfer box 405, the lifting motor 304 works, and then drives the sliding block 302 to move downward, that is, drives the two storage components 4 to move downward, until the lower end surface of the lowest storage transfer box 405 contacts the upper end surface of the transfer bottom plate 1.

[0030] Further, the storage assembly 4 includes two transverse guide blocks 401 symmetrically fixedly arranged in the middle of the sliding block 302, a storage transfer box 405 is slidably arranged between the two transverse guide blocks 401, and two driving blocks 406 are symmetrically fixedly arranged on one side of the middle of the storage transfer box 405;

[0031] A driving screw 403 is rotatably provided inside the left lateral guide block 401, and a driving motor 402 is fixedly provided on one side of the middle of the left lateral guide block 401. The driving motor 402 is fixedly connected to one end of the driving screw 403, and an internal threaded through hole for matching the driving screw 403 is provided in the middle of the left driving block 406;

[0032] A fixing rod 404 is fixedly arranged inside the right lateral guide block 401, and a cylindrical through hole used to cooperate with the fixing rod 404 is opened in the middle of the right driving block 406; a limiting assembly 5 for limiting the position of high-precision parts is arranged inside the storage and transfer box 405, and the limiting assembly 5 includes a bidirectional screw rod 501 rotatably arranged at the lower part of the storage and transfer box 405, and two limiting plates 502 are symmetrically arranged in the middle of the bidirectional screw rod 501 through threaded connection, and a limiting sponge 503 is fixedly arranged on one side of the middle of the limiting plate 502;

[0033] Two driven gears 504 are fixedly provided at both ends of the bidirectional screw rod 501 outside the storage and transfer box 405, a driving rack 505 is fixedly provided at the middle of the lower end of the transverse guide block 401, the driving rack 505 and the driven gear 504 are meshed with each other, and a protective shell 506 is also fixedly provided at the lower end of the transverse guide block 401;

[0034] As can be seen from the above, when transferring high-precision parts to the storage and transfer box 405, the driving motor 402 needs to work first. The driving motor 402 can drive the driving screw 403 to rotate. The rotation of the driving screw 403 can drive the left driving block 406 to move. Since two driving blocks 406 are symmetrically fixed on one side of the middle part of the storage and transfer box 405, the storage and transfer box 405 can be extended in the two lateral guide blocks 401, thereby exposing the interior of the storage and transfer box 405.

[0035] When the storage transfer box 405 is extended, the two driven gears 504 at both ends of the two-way screw rod 501 will move forward as a whole. Since the driving rack 505 is fixed, the driven gear 504 will rotate, further driving the two-way screw rod 501 to rotate. The rotation of the two-way screw rod 501 can drive the two limit plates 502 to open, that is, when the storage transfer box 405 is extended, the two limit plates 502 inside the storage transfer box 405 are opened, and when the storage transfer box 405 is retracted, the two limit plates 502 inside the storage transfer box 405 move in the same direction, thereby clamping and limiting the high-precision parts placed inside the storage transfer box 405. The entire opening process is quick and convenient, and the operator only needs to transfer and carry it, which greatly speeds up the entire transportation process.

[0036] Furthermore, dust shields are fixedly provided at the upper ends of the two uppermost lateral guide blocks 401 , and the dust shields can effectively prevent foreign matter such as dust from entering the uppermost storage and transfer box 405 .

[0037] Furthermore, the length of the driving rack 505 is smaller than the length of the transverse guide block 401 . This arrangement can effectively ensure the normal use of the bidirectional screw rod 501 .

[0038] Furthermore, a rectangular groove for cooperating with the driving block 406 to slide is formed on the side wall of the transverse guide block 401 .

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
