DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 A flat and oblique arm assembly device for simplified arm processing is used to connect the flat arm 10 and the oblique arm 11 in the simplified arm. The flat arm 10 and the oblique arm 11 are connected by a pin shaft 3. The pin shaft 3 is detachably connected with a cotter pin 22. The device includes a pin shaft control mechanism and a cotter pin control mechanism.

[0022] The pin shaft control mechanism comprises a plurality of pin shaft transfer jaws 6 .

[0023] The cotter pin control mechanism includes a second cotter pin push rod 20 and a movably arranged cotter pin slide 18, wherein the second cotter pin push rod 20 faces below the connection between the flat arm 10 and the inclined arm 11, the cotter pin slide 18 and the second cotter pin push rod 20 are parallel to each other, and the cotter pin slide 18 corresponds to or is staggered with the second cotter pin push rod 20 during movement.

[0024] The specific connection method of the flat wrist arm 10 and the oblique wrist arm 11 is as follows: the flat wrist arm 10 is fixedly connected with two mutually parallel first connecting plates 8, and the first connecting plate 8 is provided with a first pin hole for penetrating the pin shaft 3; the oblique wrist arm 11 is fixedly connected with a second connecting plate 9, and the second connecting plate 9 is provided with a second pin hole for penetrating the pin shaft 3; one end of the pin shaft 3 is integrally connected with a head 23, and a cotter pin insertion hole 24 for penetrating the cotter pin 22 is provided near the other end of the pin shaft 3. When connecting, the second connecting plate 9 is inserted between the two first connecting plates 8, and the first pin hole and the second pin hole are aligned, and then the pin shaft 3 is passed through the first pin hole and the second pin hole, and finally the cotter pin 22 is inserted into the cotter pin insertion hole 24 to complete the connection between the flat wrist arm 10 and the oblique wrist arm 11.

[0025] When in use, the pin shaft 3 is transferred using the pin shaft transfer jaw 6 until the pin shaft 3 passes through the first pin hole and the second pin hole. At this time, the head 23 is located at the top and the cotter pin hole 24 is located at the bottom, and the cotter pin hole 24 extends out of a first connecting plate 8 located below. The cotter pin slide 18 is then used to transfer the cotter pin 22 to the position corresponding to the cotter pin hole 24. Finally, the second cotter pin push rod 20 is used to push the cotter pin 22 in the cotter pin slide 18 into the cotter pin hole 24.

[0026] The present invention can automatically complete the installation of the pin shaft 3 and the cotter pin 22, thereby realizing the assembly of the flat arm 10 and the oblique arm 11, thereby effectively improving the processing efficiency of the simplified arm.

[0027] In order to enable the pin transfer jaw 6 to complete the transfer of the pin 3 and the insertion of the pin 3 into the pin hole, the pin control mechanism includes a pin transverse conveying unit 4, which is driven and connected to a plurality of pin lifting slides 5, and the pin locking jaws 12 are fixedly connected to the pin lifting slides 5 one by one. The pin shaft lateral conveying unit 4 is used to drive the pin shaft lifting slide 5 to move, and then drive the pin shaft transfer jaw 6 to move through the pin shaft lifting slide 5. When the pin shaft transfer jaw 6 moves to the position corresponding to the first pin hole, the pin shaft lifting slide 5 can drive the pin shaft transfer jaw 6 to move toward the first pin hole until the pin shaft 3 is inserted into the first pin hole and the second pin hole. Considering that the pin shaft transfer jaw 6 needs to clamp a part of the pin shaft 3, it is difficult to install the pin shaft 3 in place. Therefore, in the present invention, the first connecting plate 8 and the second connecting plate 9 are both horizontally arranged. After the pin shaft transfer jaw 6 inserts the pin shaft 3 into the first pin hole, the pin shaft 3 is released and the pin shaft 3 can be installed in place with the help of the gravity of the pin shaft 3, thereby achieving the effect of simplifying the installation process.

[0028] The specific structure of the pin shaft transverse conveying unit 4 is as follows: the pin shaft transverse conveying unit 4 includes a fixedly connected transverse push cylinder 15 and a guide rail 16, the guide rail 16 is slidably connected with a mounting plate 17, the transverse push cylinder 15 is drivingly connected with the mounting plate 17, and the pin shaft lifting slide 5 is fixedly arranged on the mounting plate 17. When in use, the transverse push cylinder 15 pushes the mounting plate 17 to move, and then drives the pin shaft lifting slide 5 to move through the mounting plate 17, and the guide rail 16 is used to limit the mounting plate 17 to avoid deviation.

[0029] In order to prevent the cotter pin 22 from pushing the pin shaft 3 to rotate during the movement, so that the cotter pin 22 cannot be smoothly inserted into the cotter pin insertion hole 24, the pin shaft control mechanism includes a pin shaft locking jaw 12, which is arranged below the connection between the flat arm 10 and the oblique arm 11, and the second cotter pin push rod 20 faces the pin shaft locking jaw 12. After the pin shaft 3 passes through the first pin hole and the second pin hole, the pin shaft 3 is locked by the pin shaft locking jaw 12 to prevent the pin shaft 3 from rotating.

[0030] Taking into account that the pin shaft 3 itself is cylindrical, it is very likely to rotate during the transfer process, which will cause the direction of the cotter pin hole 24 to change, and ultimately cause the cotter pin 22 to be unable to be smoothly inserted into the cotter pin hole 24. In order to avoid this situation, the pin shaft control mechanism includes a motor 25 and a pin shaft adjustment clamp 7 driven by the motor 25, and the pin shaft adjustment clamp 7 is arranged in parallel with the pin shaft locking clamp 12, and at least one sleeve 27 is passed through the pin shaft adjustment clamp 7, and the sleeve 27 is connected to the cavity 26 of the pin shaft adjustment clamp 7, and a telescopic rod 28 is telescopically arranged in the sleeve 27, and the bottom of the pin shaft adjustment clamp 7 is fixedly connected to the motor 25. After obtaining the pin 3, the pin transfer jaw 6 first sends the pin 3 into the pin adjustment jaw 7. After the pin 3 enters the cavity 26, the pin transfer jaw 6 continues to clamp the pin 3, and then the motor 25 starts to drive the pin adjustment jaw 7 to rotate. During the rotation of the pin adjustment jaw 7, the telescopic rod 28 maintains a tendency to extend. When the telescopic rod 28 corresponds to the cotter pin socket 24, the telescopic rod 28 can smoothly enter the cotter pin socket 24, and then the pin transfer jaw 7 releases the pin 3, and then the motor 25 is reset, and the pin 3 is driven to rotate by using the telescopic rod 28 and the pin adjustment jaw 7. After the motor is reset 25, the direction of the cotter pin socket 24 is fixed, and then the pin transfer jaw 6 is used to clamp the pin 3 again and transfer it to the pin locking jaw 12. After adjustment by the pin shaft adjusting jaw 7, the directions of the cotter pin holes 24 on all the pin shafts 3 in the pin shaft locking jaw 12 transferred by the pin shaft transfer jaw 6 are the same. By controlling the motor 25, it can be ensured that the cotter pin hole 24 and the second cotter pin push rod 20 correspond to each other after the pin shaft 3 enters the pin shaft transfer jaw 12, thereby ensuring that the second cotter pin push rod 20 can smoothly insert the cotter pin 22 into the cotter pin hole 24.

[0031] The telescopic rod 28 is specifically arranged as follows: a connecting ring is fixedly arranged on the inner wall of the end of the sleeve 27 away from the cavity 26, the telescopic rod 28 passes through the connecting ring, the middle of the telescopic rod 28 is fixedly connected to a limiting block 29, and the limiting block 29 is connected to the connecting ring by a spring 30. In the initial state, the spring 30 remains original, and a part of the telescopic rod 28 is located in the cavity 26. When the pin 3 enters the cavity 26, the telescopic rod 28 is squeezed into the sleeve 27, and the spring 30 is compressed by the limiting block 29, so that the telescopic rod 28 can maintain the tendency to extend during the rotation of the pin adjustment jaw 7.

[0032] In order to ensure that the pin shaft 3 can smoothly enter into the cavity 26 and can be smoothly withdrawn from the cavity 26 , a hemispherical positioning plug 31 is fixedly connected to one end of the telescopic rod 28 facing the cavity 26 .

[0033] The structure of the cotter pin control mechanism further includes: the cotter pin control mechanism includes a slideway regulating cylinder 14, the slideway regulating cylinder 14 is driven and connected to the moving plate 13, the cotter pin slideway 18 is opened on the moving plate 13, and the moving plate 13 is also provided with a cotter pin material rack 21, and the cotter pin material rack 21 contains a plurality of cotter pins 22 distributed up and down. When in use, the slideway regulating cylinder 14 first drives the moving plate 13 to move the cotter pin slideway 18 to the bottom of the cotter pin material rack 21, so as to receive the cotter pin 22 dropped from the cotter pin material rack 21, and then the slideway regulating cylinder 14 drives the moving plate 13 to move until the cotter pin slideway 18 corresponds to the second cotter pin push rod 20, and the cotter pin 22 in the cotter pin slideway 18 can be pushed into the cotter pin insertion hole 24 by using the second cotter pin push rod 20.

[0034] In order to avoid the jamming of multiple cotter pins 22 entering the cotter pin slideway 18 at one time, the cotter pin control mechanism includes a first cotter pin push rod 19 parallel to the second cotter pin push rod 20, the first cotter pin push rod 19 faces the bottom of the cotter pin material rack 21, and the cotter pin slideway 18 corresponds to or staggers with the first cotter pin push rod 19 during movement. Accordingly, the cotter pin material rack 21 can be set to a structure similar to a clip, that is, a pushing component for outputting a downward thrust, such as a spring, is set at the top of the cotter pin material rack 21, and a limit plate is set at the bottom of the cotter pin material rack 21. The limit plate is used to prevent the cotter pins 22 from automatically falling. Only when one cotter pin 22 is pushed from the cotter pin material rack 21 to the cotter pin slideway 18 by the first cotter pin push rod 19 and the first cotter pin push rod 19 is retracted, the pushing component can push the remaining cotter pins 22 to move downward, thereby realizing the stable feeding of the cotter pins 22 and avoiding the jamming of the cotter pin slideway 22.

[0035] In order to achieve stable feeding of the pins 3, the device includes a horizontally arranged pin channel 1, which is fixedly arranged on a support seat 1, and contains a plurality of pins 3 arranged in parallel, and the pin channel 1 is lower than the pin transfer clamp 6. The pin channel 1 can adopt a structure similar to the open pin material rack 21.

[0036] In a specific embodiment of the present invention, two pin transfer jaws 6 are provided, and two corresponding pin lifting slides 5 are also provided. The two pin transfer jaws 6 move synchronously. When the first pin transfer jaw 6 sends the pin 3 in the pin adjustment jaw 7 into the first pin hole and the second pin hole and falls into the pin locking jaw 12, the second pin transfer jaw 6 can synchronously obtain a pin 3 from the pin material channel 1 and send it into the pin adjustment jaw 7, thereby avoiding the pin adjustment jaw 7 and the pin locking jaw 12 from being idle for a long time, thereby speeding up the assembly efficiency.

[0037] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
