Detailed Implementation

[0032] Because existing technologies for carpal tunnel production workbenches are mainly suitable for manual assembly, it is difficult to integrate carpal tunnel production workbenches into automated production lines.

[0033] In view of this, this solution provides a workbench for the production of a wrist arm, including a circulating workstation mechanism 10.

[0034] The following combination Figures 1-9 The structure and shape of the workbench used in the production of the cantilever arm are described in detail:

[0035] The circulating station mechanism 10 includes a conveying structure 100 and a locking and positioning structure 200; the conveying structure 100 includes a conveying component 110; the locking and positioning structure 200 includes a locking component 210 and a positioning component 220; the conveying component 110 is configured to drive the locking component 210 to move along the length of the pipe, so that the locking component 210 moves to the pipe locking height, thereby locking and fixing the pipe; the conveying component 110 is configured to drive the positioning component 220 to move along the length of the pipe, so that the positioning component 220 moves to the fitting installation position, thereby locking and fixing the fitting.

[0036] In this embodiment, the conveying component 110 drives the locking component 210 to move along the length of the pipe, so that the locking component 210 moves to the pipe locking height, and then the locking component 210 locks and fixes the pipe. Then the conveying component 110 drives the positioning component 220 to move along the length of the pipe, so that the positioning component 220 moves to the accessory installation position, and then the positioning component 220 locks and fixes the accessory.

[0037] The first embodiment in which the positioning component 220 locks and secures the accessory in its mounting position is as follows:

[0038] In this embodiment, the accessory supply device fits the accessory onto the pipe and moves it to its installation position. At the same time, the transport component 110 drives the positioning component 220 to move towards the accessory installation position. After the accessory and the positioning component 220 move to the installation position, the positioning component 220 clamps and fixes the accessory. Then, the accessory supply device releases the accessory. This embodiment is applicable to accessory supply devices that can fit accessories onto pipes.

[0039] In a second embodiment, the positioning component 220 locks the accessory in place at its mounting position as follows:

[0040] In this embodiment, the accessory supply device sets the accessory onto the pipe, while the conveying component 110 moves the positioning component 220 toward the accessory set position. After the accessory and the positioning component 220 move to the junction position, the positioning component 220 clamps and fixes the accessory. Then the accessory supply device releases the accessory, and then the conveying component 110 moves the accessory to its installation position through the positioning component 220. This embodiment is applicable to accessory supply devices that can set accessories onto pipes.

[0041] The third embodiment in which the positioning component 220 locks and secures the accessory in its mounting position is as follows:

[0042] In this embodiment, the accessory supply device moves the accessory above the pipe, and at the same time, the conveying component 110 drives the positioning component 220 to move toward the accessory. After the positioning component 220 moves to the location of the accessory, it clamps and fixes the accessory. Then, the accessory supply device releases the accessory, and then the conveying component 110 drives the accessory to its installation position through the positioning component 220. This embodiment is applicable to accessory supply devices that can move accessories directly above the pipe.

[0043] Regarding the shape and structure of the conveying structure 100, specifically:

[0044] like Figures 2-3 As shown, the conveying structure 100 also includes a lifting component 120; the lifting component 120 includes a lifting circular rail 121, a lifting screw 122, and a lifting motor 123; the rotation shaft of the lifting motor 123 is connected to the lifting screw 122; the lifting circular rail 121 is inserted into the conveying component 110 and is slidably connected to the conveying component 110; the lifting screw 122 is inserted into the conveying component 110 and is threadedly connected to the conveying component 110; the lifting motor 123 drives the lifting screw 122 to rotate, so that the conveying component 110 moves along the lifting circular rail 121.

[0045] To enable the conveying component 110 to be connected to the locking component 210 or the positioning component 220:

[0046] like Figures 3-4 As shown, the conveying component 110 includes a conveying support 111, a conveying cylinder 112, and two conveying grippers 113; the conveying cylinder 112 is mounted on the conveying support 111 and is configured to drive the two conveying grippers 113 to move toward each other, thereby clamping the locking component 210 or the positioning component 220.

[0047] In this embodiment, the lifting motor 123 drives the lifting screw 122 to rotate, so that the transport support 111 moves along the lifting circular rail 121. The transport support 111 drives the transport gripper 113 to move through the transport cylinder 112. After the locking component 210 or the positioning component 220 is located between the two transport grippers 113, the transport cylinder 112 drives the two transport grippers 113 to move towards each other to clamp the locking component 210 or the positioning component 220. Then, the lifting motor 123 drives the lifting screw 122 to rotate, so that the transport support 111 moves along the lifting circular rail 121, thereby driving the locking component 210 or the positioning component 220 to move.

[0048] Regarding the shape and structure of the locking and positioning structure 200, specifically:

[0049] like Figure 2 , Figure 5 and Figure 6As shown, the locking component 210 includes a locking support 211, a locking cylinder 212, and two locking jaws 213; the locking cylinder 212 is mounted on the locking support 211 and configured to drive the two locking jaws 213 to move towards each other, thereby clamping the pipe; the positioning component 220 includes a positioning support 221, a positioning cylinder 222, and two positioning jaws 223; the positioning cylinder 222 is mounted on the positioning support 221 and configured to drive the two positioning jaws 223 to move towards each other, thereby clamping the fitting.

[0050] In order to fix the locking component 210 and the positioning component 220 at a set height:

[0051] like Figure 2 , Figure 5 and Figure 6 As shown, the locking and positioning structure 200 also includes a positioning slide rail 230; the locking component 210 also includes a locking electromagnet 214; the locking support 211 is fitted onto the positioning slide rail 230 and is slidably connected to the positioning slide rail 230; the locking electromagnet 214 is installed on the locking support 211; the telescopic end of the locking electromagnet 214 extends out to abut against the positioning slide rail 230, thereby fixing the locking component 210 to the positioning slide rail 230; the positioning component 220 also includes a positioning electromagnet 224; the positioning support 221 is fitted onto the positioning slide rail 230 and is slidably connected to the positioning slide rail 230; the positioning electromagnet 224 is installed on the positioning support 221; the telescopic end of the positioning electromagnet 224 extends out to abut against the positioning slide rail 230, thereby fixing the positioning component 220 to the positioning slide rail 230.

[0052] To improve the connection strength between the locking component 210 and the positioning component 220 and the positioning slide rail 230:

[0053] like Figure 2 As shown, the outer surface of the positioning slide rail 230 is provided with a reinforcing groove to increase the contact area between the telescopic ends of the locking electromagnet 214 and the positioning electromagnet 224 and the positioning slide rail 230.

[0054] To prevent the locking component 210 and the positioning component 220 from moving along the positioning slide rail 230:

[0055] like Figures 5-6 As shown, both the locking support 211 and the positioning support 221 are fitted with damping rings; the damping rings are fitted onto the positioning slide rail 230 and are slidably connected to the positioning slide rail 230, which increases the friction between the locking support 211 and the positioning support 221 and the positioning slide rail 230, thereby preventing the locking component 210 and the positioning component 220 from moving along the positioning slide rail 230.

[0056] In this embodiment, the conveying structure 100 drives the locking support 211 to move along the positioning slide rail 230. The locking support 211 drives the two locking jaws 213 to move to the pipe clamping position through the locking cylinder 212. Then, the locking cylinder 212 drives the two locking jaws 213 to move towards each other so that the two locking jaws 213 clamp and fix the pipe. At the same time, the telescopic end of the locking electromagnet 214 extends so that the telescopic end of the locking electromagnet 214 abuts against the positioning slide rail 230, thereby fixing the locking support 211 to the positioning slide rail 230. The locking electromagnet 214 is a push-pull type electromagnet.

[0057] The conveying structure 100 drives the positioning support 221 to move along the positioning slide rail 230. The positioning support 221 drives the two positioning jaws 223 to move to the pipe clamping position through the positioning cylinder 222. Then, the positioning cylinder 222 drives the two positioning jaws 223 to move towards each other so that the two positioning jaws 223 clamp and fix the pipe. At the same time, the telescopic end of the positioning electromagnet 224 extends so that the telescopic end of the positioning electromagnet 224 abuts against the positioning slide rail 230, thereby fixing the positioning support 221 to the positioning slide rail 230. The positioning electromagnet 224 is a push-pull type electromagnet.

[0058] To avoid damage to the pipes during the installation of accessories:

[0059] like Figure 1 , Figure 2 and Figure 7 As shown, the cyclic workstation mechanism 10 also includes an auxiliary structure 300; a positioning component 220 is disposed between the locking component 210 and the auxiliary structure 300; the auxiliary structure 300 includes a three-jaw chuck 310; one end of the pipe is fixed by the three-jaw chuck 310, and the other end is fixed by the locking component 210.

[0060] To accommodate the requirement of installing multiple fittings on pipes at different angles:

[0061] like Figure 7 As shown, the auxiliary structure 300 also includes an angle adjustment frame 320, an angle adjustment motor 330, and an angle adjustment turntable 340; the angle adjustment motor 330 is installed on the angle adjustment frame 320, and its rotating end is connected to the angle adjustment turntable 340; the three-jaw chuck 310 is installed on the angle adjustment turntable 340; the angle adjustment motor 330 drives the angle adjustment turntable 340 to rotate, so that the three-jaw chuck 310 drives the pipe to rotate.

[0062] To ensure stability during pipe rotation:

[0063] like Figure 5 As shown, the locking component 210 also includes two lubrication arc plates 215; the lubrication arc plates 215 are connected to the locking jaws 213 and are used to reduce the friction between the pipe and the locking jaws 213 during the pipe rotation process.

[0064] To reduce the frictional force experienced by the pipe during rotation, the lubricating arc plate 215 includes an arc-shaped plate and graphite columns embedded in the arc-shaped plate. The rotation of the pipe causes the graphite columns to wear, thereby forming a lubricating film between the pipe and the arc plate.

[0065] In this embodiment, the pipe supply equipment places the pipe into the clamping position, then the three-jaw chuck 310 clamps and fixes one end of the pipe. Next, the conveying structure 100 and the locking and positioning structure 200 cooperate to fix the fitting in the installation position. Then, the locking component 210 clamps and fixes the end of the pipe away from the three-jaw chuck 310, so that both ends of the pipe are supported during the installation of the fitting, avoiding the impact of the fitting installation on the pipe.

[0066] When multiple accessories need to be installed on the pipe at different angles, after the first accessory is installed, the handling structure 100 and the locking and positioning structure 200 cooperate to fix the second accessory in the installation position. Then, the locking cylinder 212 drives the two lubrication arc plates 215 to move towards each other through the locking jaws 213, so that the two lubrication arc plates 215 abut against the pipe. At this time, the air pressure input to the locking cylinder 212 is less than the air pressure input to the locking cylinder 212 when locking the pipe. Then, the angle adjustment motor 330 drives the three-jaw chuck 310 to rotate through the angle adjustment turntable 340. The three-jaw chuck 310 drives the first accessory to rotate through the pipe, so that the first accessory and the second accessory reach the installation angle. During this process, the lubrication arc plate 215 provides support for the end of the pipe away from the three-jaw chuck 310 while reducing the friction force borne by the pipe during rotation.

[0067] In order to move the circulating station mechanism 10 to different processes:

[0068] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a positioning mechanism 20; the positioning mechanism 20 includes a positioning bracket 21, a positioning motor 22, a positioning shaft 23, and a positioning turntable 24; the positioning motor 22 is mounted on the positioning bracket 21; one end of the positioning shaft 23 is connected to the rotating end of the positioning motor 22, and the other end is connected to the positioning turntable 24; the circulating station mechanism 10 is mounted on the positioning turntable 24; the positioning motor 22 drives the positioning shaft 23 to rotate, so that the positioning turntable 24 drives the circulating station mechanism 10 to rotate.

[0069] In this embodiment, the adjustment motor 22 drives the adjustment shaft 23 to rotate, so that the adjustment turntable 24 drives the circulating station mechanism 10 to rotate, thereby causing the circulating station mechanism 10 to pass through the pipe disassembly and assembly process, the accessory assembly process and the accessory installation process in the production line in sequence. The circulating station mechanism 10 first fixes the pipe, then sets the accessory onto the pipe and fixes it to the installation position, and then fixes the accessory to the pipe.

[0070] To accelerate the production speed of the wrist arm:

[0071] like Figure 1 As shown, it also includes multiple circulating workstation mechanisms 10; the multiple circulating workstation mechanisms 10 are all installed on the adjustment turntable 24, and the multiple circulating workstation mechanisms 10 are distributed in a ring array around the axis of the adjustment turntable 24; the adjustment turntable 24 drives the multiple circulating workstation mechanisms 10 to rotate, so that the multiple circulating workstation mechanisms 10 move to different processes to assemble pipes and fittings.

[0072] In this embodiment, multiple cyclic workstation mechanisms 10 enable the pipe disassembly and assembly process, the accessory assembly process, and the accessory installation process in the production line to be carried out simultaneously, thereby reducing the idle time of the process and speeding up the production speed of the cantilever arm.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
