Description

Technical Field

[0001] The utility model relates to the technical field of bearing copper sleeve processing, in particular to a positioning mechanism for processing self-lubricating bearing copper sleeves. Background Art

[0002] Self-lubricating bearings are mechanical devices with good wear resistance, low friction coefficient, and long service life. In addition, self-lubricating bearings have appropriate elasticity and plasticity, which can distribute stress on a wider contact surface and improve the bearing's load-bearing capacity. For the processing of self-lubricating bearings, the most critical part is the processing of the sleeve. Copper is currently widely used as the processing material. The processing of the copper sleeve structure is usually carried out in multiple steps. First, the copper tube is cut into bearing copper sleeves of equal size according to size, and then the bearing copper sleeves are drilled. During the drilling process, since there are many drilling positions, the position of the copper sleeve needs to be adjusted. Currently, there is no multi-directional positioning device dedicated to bearing copper sleeves on the market. For this reason, the utility model proposes a positioning mechanism for processing self-lubricating bearing copper sleeves. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0017] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] See also Figure 1-3In this embodiment, a positioning mechanism for processing a self-lubricating bearing copper sleeve is provided, including a processing body 1, the processing body 1 including a processing table 11, a support seat 12 installed on the lower surface of the processing table 11, a rotating mechanism 7 is provided on the processing table 11, and a positioning mechanism 8 is installed on the processing body 1 below the rotating mechanism 7. A through hole is opened in the center of the processing table 11, and the rotating mechanism 7 includes a rotating table 70 arranged in the through hole. A positioning groove 72 is opened on the upper surface of the rotating table 70, and a rotating motor 71 is installed on the lower surface of the rotating table 70 to drive it to rotate. A fixing member 4 is provided on the upper surface of the rotating table 70, and limiting balls are movably installed on both sides of the fixing member 4. The fixing member 4 includes a fixing cylinder fixed to the upper surface of the rotating table 70, and an articulated frame 481 is hinged on the outer side wall of the fixing cylinder. A rotating rod 482 is rotatably installed on the upper side of the articulated frame 481. The limiting ball is an eccentric ball 483, and the eccentric ball 483 is rotatably installed on the rotating rod 482. First, the shaft The copper sleeve 3 is placed on the rotating table 70 and is arranged on the outside of the eccentric ball 483 of the fixing part 4. When the copper sleeve 3 is located above the eccentric ball 483 and moves downward, the inner wall of the copper sleeve 3 contacts and rubs against the outer surface of the eccentric ball 483, causing the eccentric ball 483 to rotate on the rotating rod 482. Rotating the eccentric ball 483 can gradually increase the distance between the rotating rod 482 and the inner wall of the copper sleeve 3. When the copper sleeve 3 is completely moved down and falls into the positioning groove 72, the copper sleeve 3 will be tightened by the eccentric ball 483 inside, thereby fixing the position of the copper sleeve 3, preventing the copper sleeve 3 from moving during subsequent processing, and improving the stability during processing. After drilling at the same position is completed, the rotating table 70 is driven to rotate by driving the rotating motor 71, thereby driving the copper sleeve to rotate, thereby facilitating the drilling of other positions on its surface and realizing drilling of different positions on the same horizontal plane of the copper sleeve.

[0019] In this embodiment, the positioning mechanism 8 includes a sliding limit frame 84 installed on the lower surface of the processing table 11, and a base plate 85 is fixedly installed at the lower end of the sliding limit frame 84. A threaded rod 81 is rotatably installed on the upper end of the base plate 85, and the threaded rod 81 and the sliding limit frame 84 are arranged parallel to each other. A positioning motor 80 for driving the rotation of the threaded rod 81 is installed on the upper end of the threaded rod 81. The outer surface of the threaded rod 81 is threadedly connected to a threaded sleeve 82, and one side of the threaded sleeve 82 is fixedly connected to a horizontally arranged sliding bracket 83, and the sliding bracket 83 is slidably installed on the sliding limit frame 84. In order to perform drilling processing at different height positions of the bearing copper sleeve, the threaded rod 81 is driven to rotate by the positioning motor 80, which can drive the threaded sleeve 82 to be vertically moved. The displacement in the direction of rotation drives the sliding bracket 83 to move up and down on the sliding limit frame 84, and then drives the rotating table 70 to rise or fall, thereby completing the adjustment of the height position of the copper sleeve on its surface. The positioning mechanism 8 can not only be used to adjust the processing height as needed, so that holes can be drilled at different height positions on its surface, but also the direction of the bearing copper sleeve can be arbitrarily rotated by setting the rotating table and rotating motor of the rotating mechanism. The vertical position of the bearing copper sleeve can be adjusted by setting the positioning motor, threaded rod, threaded sleeve, sliding bracket and sliding limit frame of the positioning mechanism, so that the bearing copper sleeve can be adjusted at any position, thereby facilitating the drilling process at different positions on its surface.

[0020] It is worth noting that the entire device is controlled by a master control button. Since the devices matched with the control button are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
