DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-7 This application is described in further detail.

[0035] The present application embodiment discloses a three-dimensional multi-station warehouse processing machine tool, a three-dimensional multi-station warehouse and a station exchange platform. Figure 1 , the processing machine tool includes: A three-dimensional multi-station warehouse 100 is used to accommodate and operate multiple station boards 400, each of which can be installed with tooling or workpieces; The processing table 200 is used to fix a single work station plate 400, so that the machine tool can process the workpiece on the work station plate 400; The workstation exchange table 300 is located between the three-dimensional multi-station library 100 and the processing workbench 200 and is used to move the workstation plate 400 on the processing workbench 200 to the three-dimensional multi-station library 100 , and to move the workstation plate 400 on the three-dimensional multi-station library 100 to the processing workbench 200 .

[0036] The three-dimensional multi-station library 100 includes: The stand 110 is provided with two symmetrically arranged closed tracks 111, and the closed tracks 111 are vertically arranged in an elliptical or waist shape. In this embodiment, the closed tracks 111 are waist-shaped, that is, the upper and lower ends of the closed tracks 111 are semicircular arcs, and the middle part is a straight line; The station seat 120 has multiple and is slidably connected to the closed track 111. The sliding track of the station seat 120 has the same shape as the closed track 111. The station seat 120 is used to install the station plate 400, and the station plate 400 is used to install tooling or workpieces.

[0037] The circulating driving structure 130 is installed on the stand 110 and is used to drive the workstation seat 120 to move cyclically on the stand 110 .

[0038] Among them, two rollers 126 are rotatably connected on both sides of the workstation seat 120, and the connecting line of the two rollers 126 on the same side is perpendicular to the workstation plate 400. The two rollers 126 on the same side are placed in the same closed track 111, and the rollers 126 are used to reduce the friction between the workstation seat 120 and the stand 110.

[0039] The station seat 120 is fixedly connected with a first T-shaped block 121, and a T-shaped slot 401 adapted to the first T-shaped block 121 is provided at the bottom of the station plate 400. The station plate 400 is slidably connected to the station seat 120 through the T-shaped slot and the first T-shaped block 121. The first T-shaped block 121 is arranged along the horizontal direction and is arranged perpendicular to the closed track 111, so that the sliding direction of the station plate 400 relative to the station seat 120 is perpendicular to the sliding direction of the station seat 120. When the station seat 120 slides on the stand 110, the station plate 400 will not slide off the station seat 120, thereby improving safety.

[0040] In order to further improve safety, the station seat 120 is provided with a limiting structure 122 for limiting the movement of the station plate 400 relative to the station seat 120. The limiting structure 122 includes a positioning pin 123 slidably connected to the station seat 120, and the positioning pin 123 is sleeved with a spring 124. The station plate 400 is provided with a positioning hole 402, and the positioning pin 123 is inserted into the positioning pin 123 under the action of the spring 124. The sliding direction of the positioning pin 123 is perpendicular to the sliding direction between the station plate 400 and the station seat 120.

[0041] The station seat 120 moves on the stand 110. When the station seat 120 is located at one side of the stand 110, the station plate 400 of the station seat 120 faces upward, and the side where the station seat 120 is located is the front side of the stand 110. When the station seat 120 is located at the back side of the stand 110, the station plate 400 of the station seat 120 faces downward.

[0042] A pin block 112 is fixedly connected to the front position of the stand 110. The pin block 112 is a sheet metal part. An arc-shaped groove 113 is provided on the side of the pin block 112 facing the workstation seat 120. The arc-shaped groove 113 is vertically arranged, and its upper and lower ends penetrate the pin block 112. The horizontal cross-section of the arc-shaped groove 113 is T-shaped. An annular groove 125 is provided at one end of the positioning pin 123 so that one end of the positioning pin 123 is adapted to the arc-shaped groove 113. When the workstation seat 120 slides to the position of the pin block 112, one end of the positioning pin 123 is placed in the arc-shaped groove 113.

[0043] The side wall of the arc groove 113 away from the station seat 120 is arc-shaped, and the arc is bent in the direction away from the station seat 120. Under the action of the arc-shaped side wall, the positioning pin 123 moves away from the station plate 400 until it is disengaged from the positioning hole 402. At this time, the position of the station seat 120 is the station exchange position of the stand 110, and the station plate 400 on the station seat 120 at this position can be moved horizontally and thus removed. When the station seat 120 continues to move, under the action of the spring 124, the positioning pin 123 is reset, thereby locking the station plate 400.

[0044] The circulation drive structure 130 includes: There are two driving sprockets 131, both of which are rotatably connected to the upper end of the stand 110, and the two driving sprockets 131 are coaxially arranged; The transmission chain 133 is meshed with the driving sprocket 131 at the same time. The two driving sprockets 131 have two transmission chains 133. The station seat 120 is fixedly connected with the transmission chain 133. The movement of the transmission chain 133 drives the movement of the station seat 120. The circulating power member 134 is used to drive the driving sprocket 131 to rotate. In the embodiment of the present application, the circulating power member 134 is a hydraulic motor, and the circulating power member 134 drives the driving sprocket 131 to rotate through gear transmission, thereby driving the station seat 120 to move.

[0045] The circulating power member 134 drives the driving sprocket 131 to rotate and moves synchronously with the transmission chain 133 of the driving sprocket 131. The transmission chain 133 moves and drives the station seat 120 to slide along the closed track 111. When the station seat 120 moves to the station exchange position, under the action of the pull pin block 112, the positioning pin 123 no longer locks the station plate 400, and then the station exchange table 300 exchanges the station plate 400 with the station plate 400 on the processing workbench 200.

[0046] The processing workbench 200 includes a work plate 210 for clamping the work plate 400. The work plate 210 is fixedly connected with a second T-shaped block 211, which is adapted to the T-shaped slot 401, so that the work plate 400 is clamped to the work plate 210 through the second T-shaped block 211 and the T-shaped slot 401.

[0047] The station exchange station 300 includes: Exchange base 310; The exchange structure 320 is used to clamp the workstation plate 400 and drive the workstation plate 400 to rotate, so as to achieve the position exchange of the two workstation plates 400; The clamping structure 330 is disposed on the switching structure 320 and is used to drive the workstation plate 400 to move toward or away from the rotation center of the switching structure 320 .

[0048] The clamping structure 330 drives the work station plate 400 to move toward the center of the exchange structure 320 so that the work station plate 400 moves from the work station seat 120 or the work disk 210 to the exchange structure 320; the clamping structure 330 drives the work station plate 400 to move away from the rotation center of the exchange structure 320 and moves the work station plate 400 from the exchange structure 320 to the work station seat 120 or the work disk 210.

[0049] Specifically, the exchange structure 320 includes an exchange seat 321. The exchange seat 321 is rotatably connected to the exchange base 310, and its rotation axis is vertically arranged. The exchange seat 321 is fixedly connected to a third T-shaped block 322 arranged horizontally, and the third T-shaped block 322 is adapted to the T-shaped slot 401 of the station plate 400. The station plate 400 is slidably connected to the exchange seat 321 through the T-shaped slot and the third T-shaped block 322.

[0050] The height of the exchange seat 321 is the same as the height of the station seat 120 located at the station exchange position, and the height of the working disk 210 is the same as the height of the exchange seat 321. More specifically, the height of the third T-shaped block 322 and the height of the second T-shaped block 211 are the same as the height of the first T-shaped block 121 of the station seat 120 located at the station exchange position. The rotation of the exchange seat 321 drives the third T-shaped block 322 to rotate, so that the third T-shaped block 322 is aligned with the first and second T-shaped blocks. When the station is exchanged, the station plate 400 on the station seat 120 slides onto the exchange seat 321, and at the same time, the station plate 400 on the processing disk also slides onto the exchange seat 321, and then the exchange seat 321 rotates 180°, so that the positions of the two station plates 400 are swapped. Then push the two station plates 400 to slide off the exchange seat 321 to achieve the exchange of the station plates 400.

[0051] The exchange structure 320 also includes an exchange power member 323 that drives the exchange seat 321 to rotate. The exchange power member 323 can be a hydraulic motor, an electric motor, a cylinder, etc. In the embodiment of the present application, the exchange power member 323 adopts a hydraulic motor. The exchange power member 323 is fixedly connected to the exchange base 310, and its output shaft is coaxially fixedly connected with a first gear 324, and the exchange seat 321 is coaxially fixedly connected with a ring gear 325, and the first gear 324 meshes with the ring gear 325, thereby driving the exchange seat 321 to rotate.

[0052] The clamping structure 330 includes two pull blocks 331 slidably connected to the exchange seat 321. A clamping groove 332 is provided on the upper surface of the pull block 331. A clamping block 403 adapted to the clamping groove 332 is fixedly connected to the lower surface of one side of the work station plate 400. In this embodiment, the clamping block 403 is a cylindrical pin. When the pull block 331 is located at the edge of the exchange seat 321, the exchange seat 321 rotates to drive the pull block 331 to translate so that the clamping groove 332 is clamped with the clamping block 403, and the two pull blocks 331 are respectively clamped with the clamping blocks 403 of the two work station plates 400. The movement of the pull block 331 drives the work station plate 400 to move.

[0053] The clamping structure 330 also includes a translational force member 333, which is used to drive the two pull blocks 331 to move toward or away from each other. The translational force member 333 can be a hydraulic motor, an electric motor, a cylinder, etc. In the embodiment of the present application, the translational force member 333 adopts a hydraulic motor. Specifically, the translational force member 333 is fixedly connected to the exchange seat 321, and the exchange seat 321 is coaxially connected to the central transmission shaft 334. One end of the central transmission shaft 334 is coaxially fixedly connected to the output shaft of the translational force member 333, and the other end is coaxially fixedly connected to the second gear 335.

[0054] The exchange seat 321 is slidably connected to two racks 336 along the horizontal direction. The teeth of the two racks 336 are arranged to face each other. Each rack 336 is fixedly connected to one of the pulling blocks 331 . Both racks 336 are meshed with the second gear 335 .

[0055] The translation force member 333 drives the central transmission shaft 334 to drive the second gear 335 to rotate. The second gear 335 rotates to drive the two racks 336 to move, thereby causing the two pulling blocks 331 to slide.

[0056] The central transmission shaft 334 is threadedly connected with a contact plate 337, and the contact plate 337 is slidably connected to the exchange seat 321 along the axial direction of the central transmission shaft 334. When the central transmission shaft 334 rotates, the contact plate 337 moves upward or downward. Two limit switches 338 are installed on the exchange base 310, one limit switch 338 is located above the contact plate 337, and the other limit switch 338 is located below the contact plate 337. When the contact plate 337 moves upward to trigger the upper limit switch 338, the pull block 331 is located at the edge of the exchange seat 321, and when the contact plate 337 moves downward to trigger the lower limit switch 338, the pull block 331 is located at the center of the exchange seat 321.
