Description

Technical Field

[0001] The utility model relates to the technical field of bearing assembly, in particular to a workpiece multi-bearing fixed-angle installation device. Background Art

[0002] Bearings are an important component in mechanical equipment. Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings. Daily maintenance and care of bearings include lubrication, cleaning, installation and disassembly, operation monitoring, storage and protection. The causes of bearing wear include peeling, burning, crack defects, cage damage, etc. The treatment method is to check the machining accuracy of the shaft and bearing box, check the type of lubricant to ensure the injection amount, set appropriate interference and check the material, etc. Therefore, bearings are one of the indispensable parts in the modernization process. How to maintain the accuracy of the bearing itself when installing it and how to install the bearing without damage in the required component position are both difficult problems in the use of bearings. In the existing technology, most of them are installed in the corresponding position by overheating or overcooling to make the bearing itself expand and contract. However, it is not easy to use this method when automatically installing multiple bearings on a part, so it is generally assembled by pressing. The positioning accuracy and intelligence of the existing assembly device are not enough to meet the needs of large-scale industrial production. Utility Model Content

[0021] Embodiment 1:

[0022] like Figure 1-2As shown, a workpiece multi-bearing fixed-angle installation device includes a workbench 1, a mechanical arm 2, a feeding device 3 and a positioning device 4. The feeding device is arranged on one side of the top of the workbench 1, the positioning device 4 is arranged on the top of the workbench 1, the mechanical arm 2 is arranged on one side of the workbench 1, the feeding device 3 includes a cylinder 31, a linear guide 32 and a hydraulic cylinder 33, a bracket 6 is arranged on the top of the workbench 1, a slide plate 7 is arranged horizontally on the top of the bracket 6, and limit baffles 8 are arranged at opposite ends of the slide plate 7. The cylinder 31 is fixedly installed at one end of the top of the slide plate 7, and a circular tube 9 with a vertical axis is arranged in the middle position of the slide plate 7. There is a gap between the bottom end surface of the circular tube 9 and the top surface of the slide plate 7, and the push rod of the cylinder 31 is used to push the object away from the circular tube 9 from the gap. The linear guide 32 is arranged on the workbench 1, and the linear guide 32 is arranged on the linear guide 32. A slider 10 is slidably installed, and a fixing plate 11 is arranged on the slider 10. A positioning through hole with a vertical axis is opened at one end of the fixing plate 11. The sliding direction of the slider 10 is perpendicular to the movement direction of the push rod of the cylinder 31. A plurality of blind holes are evenly arranged axially on the inner wall of the positioning through hole. Return springs are arranged in the blind holes. A ball is arranged at one end of the return spring. When the cylinder 31 pushes the bearing to the top of the positioning through hole, the bearing falls into the positioning through hole. In order to prevent the bearing from falling directly, a protrusion that can be automatically retracted is formed by the return spring and the ball. The bearing is pressed by the hydraulic cylinder, so that the bearing can be pressed on the rotating shaft of the workpiece through the positioning through hole normally. The ball is located in the positioning through hole. A fixed frame is arranged on the top of the workbench 1. The hydraulic cylinder 33 is vertically fixedly installed at the bottom of the fixed frame. A storage bin is arranged on the top of the round tube.

[0023] like Figure 1-2 As shown, the positioning device 4 includes a fixed base 41, a servo motor 42 and a stop ring 43. The servo motor 42 is fixedly mounted on the fixed base 41, and the stop ring 43 is sleeved on the rotating shaft of the servo motor 42. The periphery of the stop ring 43 is provided with an acute-angled blunt shape. The stop ring is used to stop the bearing at a fixed point after reaching a specified position when the bearing is sleeved on the robot arm net, so as to increase the positioning accuracy and reduce the error of the positioning installation. The acute-angled blunt shape is convenient for guiding the positioning during installation. An angle limiting device 5 is provided on the base, and an angle controller is provided on the clamping jaws of the robot arm 2. A pressure plate is fixedly installed on the pressure rod of the hydraulic cylinder 33, and the pressure plate is clearance-matched with the positioning through hole.

[0024] Specific implementation process: When in use, the bearing is clamped by the robotic arm, and then the bearing is installed on the stop ring. The robotic arm does not directly release the bearing. The robotic arm and the servo motor cooperate with each other to complete the precise positioning of the bearing. During the installation process, it is necessary to complete the positioning of the bearing at multiple angles. Therefore, the angle control module provided by the robotic arm and the servo motor can avoid the problem of positioning offset.

[0025] In the embodiments disclosed in the present invention, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connect" can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the embodiments disclosed in the present invention can be understood according to specific circumstances.

[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
