Description

Technical Field

[0001] The utility model relates to the technical field of robotic arms, and particularly to a fixing device for a moving platform of a robotic arm. Background Technique

[0002] A vulcanizer is a machine for vulcanizing various rubber and plastic products, with functions such as timing mold clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. Vulcanizers are divided into three forms: electric heating, steam heating, and heat-conducting oil heating. During the processing of vulcanizers, generally multiple processes such as feeding, removing the template, and scraping the material are required.

[0003] During the processing of vulcanizers, robotic arms are usually required for cooperation. The robotic arms perform monitoring, grasping, handling work, or operating tools according to set programs, trajectories, and requirements, replacing manual labor to complete a large number of operations, reducing labor costs, and meeting the production needs of large quantities. During the movement of the robotic arms, they are driven by universal wheels. When fixing is required, the device is usually fixed by relying on the locking function of the universal wheels themselves, and the stability is poor. During the operation of the robotic arms, they may come into contact with some heavy objects, increasing the overall weight of the upper part of the device, causing the center of gravity of the device to be unstable, and possibly causing the machine to tip over and be damaged. Moreover, on some uneven ground, the fixing effect after the universal wheels are locked is also relatively poor, easily causing accidents.

[0004] Based on this, a fixing device for a moving platform of a robotic arm is proposed to solve the problems raised above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a fixing device for a moving platform of a robotic arm, which has the advantages of improving the fixing effect, etc., and solves the problem that the existing robotic arms are usually fixed by relying on the locking function of the universal wheels themselves, with poor stability.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing device for a moving platform of a robotic arm, including a chassis, an installation frame is connected to the upper part of the chassis, a robotic arm is installed on the upper side of the installation frame, a moving wheel is rotatably installed at the lower part of the chassis, and a positioning component is further arranged at the lower part of the chassis;

[0007] The positioning component includes a positioning groove, hinge seats are fixedly connected to both the left and right ends of the positioning groove, extension rods are hinged to the outside of the hinge seats, a connecting frame is fixedly connected to the end of the extension rod away from the hinge seat, an installation block is fixedly connected to the end of the connecting frame away from the extension rod, an adjusting screw is threadedly connected to the inside of the installation block, and a positioning block is rotatably connected to the lower end of the adjusting screw.

[0008] Further, the positioning groove is fixedly installed on the lower outer wall of the chassis. The number of the positioning grooves is set to two, and they are respectively located on the front and rear sides of the chassis.

[0009] Further, the number of the moving wheels is set to four. The four moving wheels include two directional wheels and two universal wheels.

[0010] Further, an adjusting nut is fixedly connected to the upper end of the adjusting screw rod.

[0011] Further, a reinforcing rod is fixedly connected between the extension rod and the connecting frame.

[0012] Further, supporting plates are fixedly connected to the left and right sides of the lower part of the positioning groove.

[0013] Further, the inner wall of the positioning groove is adapted to the extension rod.

[0014] Compared with the prior art, the present utility model provides a fixing device for a manipulator mobile gantry, having the following beneficial effects:

[0015] For this fixing device of the manipulator mobile gantry, the moving wheels are provided to facilitate the movement of the chassis to a specified position. When fixing, the extension rod is rotated along the hinge seat to an appropriate angle, and the positioning block is adjusted to a position around the chassis. By rotating the adjusting screw rod, the positioning block is driven to move downward to contact the ground, thereby increasing the contact area between the lower part of the chassis and the ground, keeping a stable center of gravity, not being prone to tipping over, reducing accidents, and solving the problem that the existing manipulator usually relies on the locking function of the universal wheels themselves to fix the device, resulting in poor stability.

A moving wheel 4 is rotatably installed at the lower part of the chassis 1. The number of the moving wheels 4 is set to four. The four moving wheels 4 include two directional wheels and two universal wheels.

[0022] In this embodiment, a positioning component is further provided at the lower part of the chassis 1. The positioning component includes a positioning groove 5. The positioning groove 5 is fixedly installed on the outer wall of the lower part of the chassis 1. Hinge seats 6 are fixedly connected to both the left and right ends of the positioning groove 5. An extension rod 7 is hinged to the outside of the hinge seat 6. A connecting frame 8 is fixedly connected to the end of the extension rod 7 away from the hinge seat 6.
