Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a manipulator. Background Art

[0002] In the process of traditional injection molding machines, materials are usually unloaded manually. With the continuous development of technology, most manufacturers now use robots to unload materials from injection molding machines to improve processing efficiency. A robot is an automatic operating device that can imitate certain movements of human hands and arms to grab, move objects or operate tools according to a fixed program. It is characterized by being able to complete various expected operations through programming, and has the advantages of both human and mechanical machines in terms of structure and performance.

[0003] For example, in the manipulator with the prior art publication number CN205600550U, the steel ball of the utility model plays the role of clamping the workpiece, and the steel ball will not damage the workpiece due to the action of the limiting block of the cone rod and the cavity clamping column bracket, and the radius of the steel ball is larger than the radius of the ball-bearing hole, so the steel ball will not fall out of the hole. The sliding groove and the sliding block cooperate with each other, and when the limiting block fails, the sliding block and the sliding groove can also play a substitute role.

[0004] However, the above-mentioned prior art still has the following problems when in use: a hydraulic system is usually provided on an existing manipulator, and the hydraulic pipe is one of the components of the hydraulic system. When the manipulator makes a movement, the hydraulic pipe will move together and produce a large amplitude, which will affect the connection firmness at the hydraulic pipe interface. Based on this, the utility model provides a manipulator with a hydraulic pipe limiter. Utility Model Content

When the hydraulic pipe rotates with the second robot arm, the limiting ring can support and limit the hydraulic pipe, so as to avoid excessive shaking of the hydraulic pipe and affect the firmness of the interface between the hydraulic pipe and the hydraulic clamp, thereby ensuring the normal operation of the hydraulic clamp to solve the problems arising from the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manipulator, comprising a base, an electric slide is fixedly provided on the top of the base, a first mechanical arm is fixedly provided on the top of the electric slide, a second mechanical arm is provided at the front end of the first mechanical arm, a hydraulic clamp is provided at the front end of the second mechanical arm, a hydraulic pipe is fixedly provided on the top of the hydraulic clamp, a round rod is fixedly provided at the rear end of the second mechanical arm, a first threaded hole is opened at the rear end of the round rod, a first threaded rod is threadedly connected to the first threaded hole, a gooseneck is rotatably provided at the rear end of the first threaded rod, a second threaded rod is rotatably provided on the top of the gooseneck, a limiting ring is threadedly connected to the top of the second threaded rod, and the limiting ring is sleeved on the hydraulic pipe to limit the hydraulic pipe.

[0007] In a preferred embodiment, a second threaded hole is formed at the bottom end of the limiting ring, and the top end of the second threaded rod is disposed in the second threaded hole and threadedly connected to the second threaded hole, so that the staff can easily disassemble the limiting ring for replacement.

[0008] In a preferred embodiment, a contact switch is fixedly provided on one side of the base, and the contact switch is provided on one side of the second robotic arm for detecting the movement of the second robotic arm.

[0009] In a preferred embodiment, a first servo motor is fixedly embedded in the front end of the first robotic arm, and the front end of the output shaft of the first servo motor contacts the rear end of the second robotic arm. The second robotic arm is driven to rotate by the first servo motor, so as to drive the hydraulic clamp to move and clamp the workpiece in the injection molding machine.
