[0050] Specifically, the turntable conveying device 4 also includes: a position detection mechanism, which is installed on the first base 401. The position detection mechanism includes: a first detection member and a second detection member. The first detection member is used to detect the first extreme position of the workbench 3, and the second detection member is used to detect the second extreme position of the workbench 3. The first detection member and the second detection member are connected to the electrical signal of the electrical control system of the production line, and the accuracy of the positioning of the workbench 3 is improved by the first detection member and the second detection member.

[0051] Specifically, Figure 5 As shown, the first detection member and the second detection member are installed on the upper end of the turntable 402 through a bracket, and the first detection member and the second detection member both use proximity switches. The second hook member 405 is installed with a first detection block 408 and a second detection block 409 arranged at intervals.

In the second conveying position 407, the first detection member and the second detection member are installed in a high position, and the first detection member and the second detection member in this position are used to sense the second detection block 409. By changing the height position, it is ensured that the hook mechanism 403 can work stably in the first conveying position 406 and the second conveying position 407.

[0052] Specifically, Figure 8 As shown, the first positioning mechanism 503 includes: a connector, there are multiple connectors and they are arranged in two rows, the upper end of the connector has a conical first plug-in end 505, the positioning hole 506 is a conical structure that matches the shape of the first plug-in end 505, and the conical positioning structure has good position adjustment capability, so that the workbench 3 can be accurately positioned on the tray 502.

The plug 507 has an inserting part at the upper and lower ends respectively. The lower inserting part is slidably inserted in the through hole correspondingly opened at the lower end of the cylinder body 508, and the upper inserting part is slidably inserted in the through hole correspondingly opened in the middle part of the tray 502. The lower end of the piston 507 is fixedly connected to a second rotating shaft 509 rotatably connected to the second base 501.

The second base 501 is equipped with a motor, and the motor is equipped with a second gear 512 meshing with the first gear 511. In this structure, since the height position of the piston 507 is fixed, when oil enters the first oil chamber or the second oil chamber, the overall structure formed by the driving cylinder body 508 and the tray 502 moves up and down. The downward movement of the piston 507 drives the movement of the tray 502, so that the workbench 3 can be moved downward, and the first plug-in end 505 is inserted into the positioning hole 506 to realize the positioning function. At the same time, the workbench 3 can be pressed against the first plug-in end 505 to improve the stability of positioning.

The second base 501 is slidably installed on the X-axis drive mechanism of the horizontal machining center through a slider guide mechanism, and the screw nut transmission mechanism of the X-axis drive mechanism transmits the power of the motor to the second base 501, so that the second base 501 drives the worktable 3 to move along the X-direction feed.

[0056] The working process of this kind of parts processing flexible production line is as follows:

[0057] (1) The workpieces to be processed are uniformly mounted on the workbench 3 in the loading and unloading area, and the workbench 3 is driven by the mobile pallet 201 to move toward the machining center 5 in sequence;

[0058] (2) When the first processing center 5 is reached, the turntable 402 rotates so that the second hooking member 405 forms a hook connection relationship with the first hooking member 301, and then the workbench 3 is dragged to the first conveying position 406 of the turntable 402 through the hooking mechanism 403. The turntable 402 rotates 180° so that the workbench 3 is transported to a position facing the processing center 5. At the same time, the hooking mechanism 403 at the second conveying position 407 forms a hook connection relationship with the second workbench 3.

[0059] (3) Oil is introduced into the second oil chamber, driving the tray 502 to move to the height corresponding to the insertion slot 302, and the hook mechanism 403 pushes the workbench 3 to move, so that the tray 502 enters the insertion slot 302 and moves into place. At the same time, the second workbench 3 is dragged into the second conveying position 407;

[0060] (4) The first oil chamber is filled with oil, and the second oil chamber is unloaded with oil, so that the tray 502 drives the workbench 3 to move downward, and the plug-in component is inserted into the positioning hole 506. The tray 502 applies downward pressure to the plug-in slot 302 to stably position the workbench 3 on the plug-in component;

[0061] (5) The machining center 5 performs corresponding machining operations on the workpiece on the workbench 3;

[0062] (6) The reverse process of the above process is adopted to move the workbench 3 back to the conveyor line 1. At this time, the second workbench 3 is simultaneously sent to the first machining center 5. The first workbench 3 moves along the conveyor line 1 to the position of the second machining center 5, and is transported to the second machining center 5 through the same conveying process mentioned above for processing until all processing steps are completed. The workbench 3 is then transported to the loading and unloading area for unloading.

[0063] This type of flexible production line for parts processing connects multiple processing centers 5 in series through a conveyor line 1 and a movable workbench 3. The parts can be processed in different steps in sequence according to the conveying order, thus forming a complete flexible production line. There is no need for manual transfer of parts between different processing centers 5, which can reduce labor costs and improve work efficiency.
