Detailed Implementation

[0028] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1 and Figure 2 As shown, a side-discharge workpiece exchange table includes an exchange table 1 with an internal lifting turntable, the lifting and rotating shaft of the lifting turntable extending to the upper surface of the exchange table 1 and having an installation plate 2.

[0030] The mounting plate 2 is provided with a double cantilever support plate 3, and a turntable door 4 is provided in the middle of the upper surface of the double cantilever support plate 3.

[0031] In this embodiment, the lifting turntable and the double cantilever support plate 3 are used to realize the interchange of internal and external workpieces. The feeding and picking process is as follows:

[0032] Feeding process: When the external drive motor moves in the forward direction, it realizes the upward movement of the double cantilever support. During this process, the double cantilever support does not rotate. Then the external drive motor continues to rotate in the same direction, realizing the double cantilever support plate 3 rotates 180° and then stops rotating. Then the drive motor continues to move in the same direction to realize the turntable descends into place.

[0033] Material handling: When the external drive motor moves in the opposite direction, it realizes the upward movement of the double cantilever support. During this process, the double cantilever support does not rotate. Then, the external drive motor continues to rotate in the opposite direction, realizing the double cantilever support plate 3 rotates 180° and then stops rotating. Then, the drive motor continues to move in the opposite direction to realize the turntable descending into place.

[0034] The two cantilever ends of the double cantilever support plate 3 are provided with axisymmetrically distributed openings 5;

[0035] A support member 6 is provided on one side of the exchange table 1. When the lifting turntable descends, the support member 6 can be inserted into the opening 5 at the cantilever end of the double cantilever support plate 3.

[0036] The cantilever end of the double cantilever support plate 3 is provided with a workpiece fixing fixture 7 located at the opening 5 and placed on the top of the support member 6.

[0037] After the workpiece is installed on the top of the support member 6 using the workpiece fixing fixture 7, the double cantilever support plate 3 is driven to rise by the lifting turntable and contact the bottom of the workpiece fixing fixture 7, so that the bottom of the workpiece fixing fixture 7 moves away from the support member 6. Then, the double cantilever support plate 3 is driven to rotate 180° by the lifting turntable to complete the loading. Conversely, the double cantilever support plate 3 is driven to fall by the lifting turntable and contact the bottom of the workpiece fixing fixture 7 with the support member 6, while the double cantilever support plate 3 moves away from the workpiece fixing fixture 7 to complete the unloading.

[0038] like Figure 1 and Figure 2 As shown, the support member 6 includes a support frame 61 whose side is connected to the side of the exchange table 1; the top of the support frame 61 is provided with a positioning support platform 62 that cooperates with the opening 5. When the lifting turntable descends, the positioning support platform 62 can be inserted into the opening 5 at the cantilever end of the double cantilever support plate 3.

[0039] like Figure 1 and Figure 3 As shown, the workpiece fixing fixture 7 includes an upper fixing plate 71 and a lower fixing plate 72 fixed to the bottom of the upper fixing plate 71; as Figure 4 As shown, an upper support column 73 is provided at the corner of the lower surface of the upper fixed plate 71; a lower support column 74 is provided at the corner of the lower surface of the lower fixed plate 72; an upper support seat 75 corresponding to the upper support column 73 is provided on the cantilever end of the double cantilever support plate 3; and a lower support seat 76 corresponding to the lower support column 74 is provided on the upper surface of the positioning support platform 62.

[0040] In order for the upper support column 73 and the lower support column 74 to cooperate with the upper support seat 75 and the lower support seat 76 respectively to play a supporting role, spherical grooves are provided on the lower end surfaces of the upper support column 73 and the lower support column 74, and spherical protrusions 77 that are adapted to the spherical grooves are provided on the upper end surfaces of the upper support seat 75 and the lower support seat 76.

[0041] like Figure 1 and Figure 2 As shown, an observation window is provided on the turntable door 4, and an observation window pressure plate 8 is provided inside the observation window.

[0042] like Figure 1 and Figure 2 As shown, in order to reduce the space occupied by the equipment structure while meeting the rotation range, the turntable door 4 adopts a Z-shaped structure.

[0043] like Figure 1 and Figure 2 As shown, in order to facilitate the adjustment of the height of the exchange station 1, an adjustment base 9 is provided on the lower surface of the exchange station 1.

[0044] In practical use, the operator connects the workpiece to the workpiece fixing fixture 7 and places the workpiece on top of the positioning support platform 62 through the workpiece fixing fixture 7. At this time, if there is a workpiece connected to the workpiece fixing fixture 7 at the other end of the double cantilever support plate 3, the lifting rotation shaft of the lifting turntable rises and simultaneously supports the workpieces on both sides of the double cantilever support plate 3. During the process of the lifting rotation shaft of the lifting turntable rising, the lower support column 74 of the workpiece fixing fixture 7 gradually disengages from the lower support seat 76, and the upper support column 73 gradually contacts the upper support seat 75, thereby lifting the workpiece.

[0045] After the lifting turntable rotates 180°, it descends. During the descent, the upper support column 73 of the workpiece fixing fixture 7 gradually detaches from the upper support seat 75, and the lower support column 74 gradually contacts the lower support seat 76, completing the position exchange of the workpieces on both sides of the double cantilever support plate 3.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
