They are widely used in various production automation industries, reducing the labor intensity and working conditions of workers.

[0003] For example, a Chinese patent document with publication number CN217072364U discloses a single-axis horizontal servo robot, including a fixed plate, a moving mechanism is provided on the front side of the fixed plate, a mounting mechanism is provided on the moving mechanism, and a robot body is provided on the mounting mechanism; the moving mechanism includes a first connecting plate fixedly connected to the left side of the front side of the fixed plate, one side of the first connecting plate is rotatably connected to a screw rod, the outer surface of the screw rod is fixedly connected to a threaded block, the front side of the threaded block is fixedly connected to a moving plate, the back side of the moving plate is fixedly connected to two sliders, the inner side of the slider is slidably connected to a slide rod, and the right side of the two slide rods is fixedly connected to a second connecting plate.

[0004] It can be seen from the above disclosed content that in the above technical scheme, the one-axis horizontal walking servo manipulator is provided with a moving mechanism, and the moving mechanism can make the manipulator move more smoothly, which can greatly improve the production efficiency and has a wider range of applications than the traditional one-axis horizontal walking servo manipulator.

[0005] However, in the process of implementing the above technical solution, the inventors found that after adding the moving mechanism, friction would be generated between the slider and the slide rod as the robot moved, requiring the motor to have greater torque, resulting in higher requirements for the motor. Therefore, there would be certain inconveniences when driving the robot to move. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a one-axis manipulator that can move smoothly, which can drive the manipulator to move smoothly and make it more convenient to drive the manipulator to move.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a single-axis manipulator that moves smoothly, comprising a fixed plate, a front side of the fixed plate being rotatably connected to a lead screw, a connecting plate being mounted on the lead screw and capable of threadedly cooperating with the lead screw, slide rails being symmetrically arranged on the fixed plate along the setting direction of the lead screw, a pulley corresponding to the slide rail being arranged on the side of the connecting plate facing the fixed plate, a plurality of pulleys being arranged at intervals from each other, the pulleys being coupled to the slide rails and capable of slidingly cooperating therebetween, a mounting device being arranged on the connecting plate, the mounting device being connected to a manipulator body, and a motor being connected to one end of the lead screw, the motor being used to drive the lead screw to rotate.

[0008] The utility model is further configured as follows: the mounting device includes a mounting block, the mounting block is fixed to the connecting plate, the mounting block is provided with a mounting groove arranged toward the back connecting plate, the mounting groove is provided with a spring and a push plate that can slide in the mounting groove, one end of the spring is fixed to the bottom of the mounting groove, and the other end is fixedly connected to the push plate, the push plate is located on a side of the back spring and is provided with a first limit rod extending outside the mounting groove, the mounting block is provided with a second limit rod, the first limit rod and the second limit rod are slidably connected with the mounting plate together, the mounting plate is connected to the manipulator body, and a locking device is connected to the push plate, and the locking device is used to lock the position of the push plate.

[0009] The utility model is further configured as follows: the locking device includes a push rod, the push rod is connected to the push plate, a locking block is provided on the outer side of the mounting block, a locking hole is provided on the locking block, the push rod can be coupled to the locking hole, and a limiting fit is formed between the two.

[0010] The utility model is further configured as follows: a rotating part is rotatably connected to the pushing plate, and the pushing rod is connected to the rotating part.

[0011] The utility model is further configured as follows: the push rod is connected with a force-applying portion extending outward.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Since the slide rail and the pulley are provided, when the motor drives the lead screw to rotate, the pulley and the slide rail are coupled with each other, so that the connecting plate can move along the direction of the lead screw as the lead screw rotates. In the process of movement, the friction generated between the pulley and the slide rail is rolling friction, which is compared with the sliding friction generated between the slider and the slide rod in the prior art, so the friction encountered by the connecting plate when moving is reduced. Therefore, the technical problem in the prior art that the friction generated by the connecting plate is large due to the setting of the slider and the slide rod, and the torque generated by the motor is high is effectively solved. In addition, in the process of movement, the pulley and the slide rail can form a sliding fit, so as to smoothly drive the manipulator to move, making it more convenient to drive the manipulator to move.

The position of plate 84 is locked. When the mounting plate 82 is installed on the mounting block 81, the push plate 84 is first pushed toward the spring 83 to squeeze the spring 83. Then, the mounting plate 82 is inserted into the second limit rod 86 through the hole on the mounting plate 82 opposite to the second limit rod 86, and then the push plate 84 is released, so that the first limit rod 85 can penetrate into the hole on the mounting plate 82 opposite to the first limit rod 85, thereby limiting the mounting plate 82 under the joint action of the first limit rod 85 and the second limit rod 86. Moreover, through the provided locking device, the push plate 84 can be locked after being pushed toward the spring 83, so that there is no need to continue pushing the push plate 84 manually, thereby facilitating the installation of the mounting plate 82.
