Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic retarder production, in particular to a manipulator used for hydraulic retarder production. Background Art
[0002] A hydraulic retarder is a type of vehicle retarder that reduces the speed of a vehicle through a hydraulic device, also known as a hydraulic deceleration device. It is a type of vehicle auxiliary braking device, used in conjunction with engine braking and exhaust braking. The working principle of a hydraulic retarder is mainly based on the retarding effect produced by liquid damping. The advantage of a hydraulic retarder is its strong braking torque, which can undertake 80% to 90% of the driving braking tasks, and is particularly suitable for large vehicles, such as mining dump trucks.
[0003] As competition in the current automotive manufacturing industry intensifies and consumer market demand upgrades, low cost, high quality and fast delivery have undoubtedly become the goals pursued by major automobile manufacturers and parts companies in their transformation and upgrading.
[0004] In the traditional processing of hydraulic retarder housing, rear cover and other parts, the retarder is placed inside the material frame during the production process. When in use, the material frame and retarder parts need to be sorted and destackered separately. Traditional sorting and destacking requires manual handling, loading and unloading of parts in each process. However, due to the large size of retarder machined parts, the labor intensity of workers is high and there are safety hazards.
[0005] The Chinese utility model patent application with the authorization publication number CN213976027U discloses a robot sorting and destacking unit for retarder parts, including a movable part and a grasping part. The movable part includes a mounting seat, on which a freely movable mechanical arm is mounted, and a first connecting flange is provided at the end of the mechanical arm; the grasping part includes an industrial camera, the front side of the industrial camera is a camera, and the rear side is provided with a second connecting flange that cooperates with the first connecting flange, and the left and right sides of the industrial camera are respectively provided with two hand grasps and three hand grasps. The material frame and the retarder parts are grasped by two hand grasps and three hand grasps respectively, with a high degree of automation, replacing manual sorting and destacking, saving human resources, and high efficiency, greatly improving the sorting and destacking efficiency.
[0006] However, when the above-mentioned hand gripper grabs the material box, due to the large size and mass of the retarder machined parts inside the parts box, the manipulator is not accurately positioned with the parts box when grabbing the parts box, and the parts box is prone to tilting forward or moving back and forth, causing the parts box to fall off, creating certain safety hazards.
