Description

Technical Field

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

[0002] The manipulator can imitate certain movements and functions of human hands and arms. It is an automatic operating device used to grab, move objects or operate tools according to a fixed procedure. It can operate in harmful environments to protect personal safety. Therefore, it is widely used in mechanical manufacturing, metallurgy, electronics, light industry, lathes and atomic energy departments. CNC turning most of the time needs to work with the manipulator. The manipulator can control the delivery of objects, such as the delivery and movement of workpieces such as DC150 stators.

[0003] For example, the Chinese patent number CN217433063U is a CNC turning center robot structure. In this utility model, a U-shaped frame, a third electric push rod, a pressure plate and a protective iron plate are designed to realize the transportation and movement of the object to be processed. However, the utility model adopts a plane pressure method for clamping, which causes the pressure plate to push the clamped object to move during the clamping process. When facing cylindrical workpieces such as stators, this type of operation will push the workpiece to move and affect the clamping stability, which is inconvenient for users. Therefore, a stator turning robot is proposed to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides a stator turning robot having the advantages of firm clamping, easy operation and convenient use, etc., which solves the problem in the comparative documents that the workpiece is easily moved due to force during clamping, affecting the clamping stability and being inconvenient for users to use.

[0006] (II) Technical solution

[0007] To achieve the above object, the utility model provides the following technical solution: a stator turning manipulator, comprising a rotating base, a mechanical arm connected to the top of the rotating base, a movable head connected to the left end of the mechanical arm, and a clamping assembly installed at the bottom of the movable head;

[0008] The clamping assembly includes a fixed frame, a first clamping arm, a driven gear, a stepping motor, a driving gear, a second clamping arm and a buffer pad. The bottom of the movable head is installed with a fixed frame, the inner rear wall of the fixed frame is connected with the first clamping arm, the interior of the fixed frame is provided with a driven gear, the inner front wall of the fixed frame is installed with a stepping motor, the rear end of the output shaft of the stepping motor is installed with a driving gear, the interior of the fixed frame is provided with a second clamping arm, and the first clamping arm and the second clamping arm are installed with buffer pads on opposite sides.

[0009] Furthermore, a support column is installed at the front end of the first clamping arm, and the rear end of the driven gear is connected to the front end of the support column.

[0010] Furthermore, a fixing column is installed at the rear end of the driving gear, and the front end of the second clamping arm is connected to the rear end of the fixing column.

[0011] Furthermore, the left side of the driven gear is meshed with the right side of the driving gear, and the rear end of the first clamping arm is rotatably connected to the inner front wall of the fixed frame through a rotating shaft.

[0012] Furthermore, the second clamping arm is located inside the fixing frame, and the second clamping arm extends to the outside of the fixing frame through openings at the bottom and left side of the fixing frame.

[0013] Furthermore, the first clamp arm extends to the outside of the fixing frame through the openings at the bottom and right side of the fixing frame, and the first clamp arm and the second clamp arm are staggered left and right.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The stator turning robot is provided with a first clamping arm and a second clamping arm which are arranged opposite to each other on the left and right sides. Under the transmission of the driving gear to the driven gear, the first clamping arm and the second clamping arm are relatively moved, thereby achieving a clamping effect on the stator. At the same time, the design of the first clamping arm and the second clamping arm being staggered can realize a continuous reduction in the clamping range of the two, thereby expanding the contraction clamping range of the first clamping arm and the second clamping arm, further ensuring the size of the clamping range interval, increasing the clamping range of the robot, making it more convenient to clamp stators of different sizes, thereby facilitating the operation and use of the staff. The covered buffer pad can effectively avoid clamping the stator, ensuring the safety and stability of the processing. The meshing of the driving gear and the driven gear can also facilitate the subsequent maintenance work of the staff, further reducing the maintenance cost and facilitating the use of the user.

[0028] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and detailed descriptions of known functions and known components are omitted. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0029] When implementing, follow these steps:

[0030] 1) First, start the output shaft of the stepper motor 404 to rotate, drive the driving gear 405 to start rotating, and use the meshing transmission to make the right driven gear 403 rotate in the opposite direction;

[0031] 2) Then, the second clamping arm 406 and the first clamping arm 402 are driven to move in an arc respectively;

At the same time, the design of the first clamping arm 402 and the second clamping arm 406 being staggered can realize the continuous reduction of the clamping range of the two, thereby expanding the contraction clamping range of the first clamping arm 402 and the second clamping arm 406, further ensuring the size of the clamping range interval, increasing the clamping range of the robot, and making it more convenient to clamp stators of different sizes, thereby facilitating the operation and use of the staff. The covering buffer pad 407 can effectively avoid clamping the stator, ensuring the safety and stability of the processing, and utilizing the meshing of the driving gear 405 and the driven gear 403 can also facilitate the maintenance work of the subsequent staff, further reducing the maintenance cost, facilitating the use of the user, and solving the problem in the comparative document that the workpiece is easily moved by force during clamping, affecting the clamping stability, and being not conducive to the use of the user.
