It has a certain degree of automation and can rely on its own power and control capabilities to achieve various industrial processing and manufacturing functions. Robots are widely used in various industrial fields such as electronics, logistics, and chemicals. The robot arm needs to use a fixture in the assembly tooling.

[0003] Patent No.: CN217572559U, mentions a robot arm assembly fixture. When the robot arm needs to be flipped, the first gear drives the rotating rod to rotate through the transmission connection between the motor and the first gear, and the rotating rod drives the turntable to rotate, so that the turntable drives the clamping mechanism and the robot arm to flip as a whole. At the same time, the balance is maintained by the balance bar, which can facilitate the assembly of the robot arm, improve the assembly efficiency, and achieve the effect of flexible use. However, the device drives the clamping mechanism and the robot arm to flip as a whole by the turntable, which will cause the robot arm to move under the turntable and other equipment. If the arm is long, its two ends will collide with the support frame. The practicality needs to be improved. Now there is an urgent need for a robot arm transmission joint assembly seat to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a robot arm transmission joint assembly seat, including an assembly plate 4, a transmission spur gear 6, a mounting cylinder 8 and a small electric push rod 14, a slewing support bearing 9 is longitudinally fixed to the upper end of the assembly plate 4, a mounting cylinder 8 is fixed through the inner ring of the slewing support bearing 9, a spur gear ring 7 is fixed to the left end of the annular side of the mounting cylinder 8, a small reduction motor 5 is installed through the inside of the assembly plate 4, a transmission spur gear 6 is installed on the shaft end of the small reduction motor 5, a lower filling seat 10 is fixed to the lower end of the mounting cylinder 8, and the lower filling seat 10 is fixed on the upper end of the lower filling seat 10. The end is adhered with a lower anti-slip rubber 11 by epoxy resin glue, an upper filling seat 13 is installed at the upper end of the installation cylinder 8, and small electric push rods 14 are longitudinally installed on the left and right sides of the lower end of the upper filling seat 13. Push plates 15 are horizontally fixed to the movable ends of the two small electric push rods 14, and an upper anti-slip rubber sheet 16 is fixed to the lower end of the push plates 15. This design solves the problem that the original device causes the turntable to drive the clamping mechanism and the robot arm to flip as a whole, which will cause the robot arm to move under the turntable and other equipment. If the arm is long, its two ends will collide with the support frame, and its practicality needs to be improved.

[0020] As the first embodiment of the utility model: the lower end of the assembly plate 4 is connected to the movable ends of the two hydraulic rods 3, and the two hydraulic rods 3 are installed at the upper end of the inner part of the supporting base 1. By adding the two hydraulic rods 3, the assembly plate 4 can be driven to rise and fall, thereby changing the overall height of the device.

[0021] The left and right sides of the supporting base 1 are both tilted and fixed with reinforcement plates 2. The added reinforcement plates 2 can improve the supporting stability of the supporting base 1. The transmission spur gear 6 is meshed with the spur gear ring 7 for transmission. When the added transmission spur gear 6 is driven to rotate, the spur gear ring 7 can be driven to rotate. When the spur gear ring 7 rotates, the installation cylinder 8 is driven to rotate, so that the transmission joint of the robot arm clamped therein can also be driven to flip in place. The front and rear ends of the installation cylinder 8 are fixed with side protection pads 12 by epoxy resin glue. The added side protection pads 12 can prevent the front and rear positions of the robot arm transmission joint from directly contacting the inner wall of the installation cylinder 8 and causing wear.

[0022] The upper anti-skid rubber sheet 16 is located directly above the lower anti-skid rubber 11. The added upper anti-skid rubber sheet 16 and the lower anti-skid rubber 11 can prevent the push plate 15 and the lower filling seat 10 from directly contacting the robot arm transmission joint and causing wear. The upper filling seat 13 and the lower filling seat 10 are both made of the same PP plastic material. The added upper filling seat 13 and the lower filling seat 10 facilitate the installation of the small electric push rod 14 and the lower anti-skid rubber 11.

[0023] As a second embodiment of the present invention: when the assembler needs to assemble the transmission joint of the robot arm, the transmission joint of the robot arm is horizontally inserted into the installation tube 8 so that it is between the two side protection pads 12 and located on the upper side of the lower anti-slip rubber sheet 11, and then the two small electric push rods 14 are started, and the two small electric push rods 14 will drive the push plate 15 to move downward, thereby causing the upper anti-slip rubber sheet 16 to be driven downward until the upper anti-slip rubber sheet 16 is pressed against the transmission joint of the robot arm. At this time, the assembler can assemble the transmission joint of the robot arm, and at the same time start the two hydraulic rods 3 to change the assembly plate 4 and the robot The height of the arm transmission joint is so that assemblers of different heights can better assemble the robot arm transmission joint. When the rest of the robot arm transmission joint needs to be assembled and used, start the small reduction motor 5, and the shaft end of the small reduction motor 5 can drive the transmission spur gear 6 to rotate at a low speed, and the transmission spur gear 6 will drive the spur gear ring 7 to rotate in meshing toward each other. When the spur gear ring 7 rotates at a low speed, it will drive the installation cylinder 8 and the inner ring of the slewing support bearing 9 to rotate at a low speed, and then the robot arm transmission joint fixed on the inside of the installation cylinder 8 will also be driven to rotate at a low speed, so that the assembler can assemble and use the rest of the robot arm transmission joint.
