Description

A copper sleeve tooling for preventing errors and omissions Technical Field

[0001] This utility model relates to the field of tooling equipment technology, specifically to a copper sleeve tooling for preventing errors and omissions. Background Technology

[0002] Copper bushings are common mechanical parts, typically used to reduce friction between shafts and holes. They are characterized by wear resistance, corrosion resistance, and self-lubrication. Careful installation of copper bushings is required to ensure a tight fit between the bushing and the base material (such as bearing housings or casings), preventing loosening or deformation. This process is usually done manually, demanding high levels of skill from workers. Large-scale assembly is extremely time-consuming and labor-intensive, and human errors such as misplacement or omission of bushings frequently occur, impacting assembly efficiency and easily leading to part scrap. An automated tooling solution is needed to address these issues. Summary of the Invention

[0003] To solve the above problems, this utility model proposes a copper sleeve tooling to prevent errors and omissions, including a fixed base. The top plate of the fixed base has a number of lifting holes in the center ring. A sensing component is provided between adjacent lifting holes. The lifting holes are vertically slidably connected to the lifting column. The lifting column passes through the lifting holes through the lifting mechanism and is inserted into the copper sleeve. The inner diameter of the copper sleeve is clearance-fitted with the outer diameter of the push rod in the sleeve removal claw. The lower end of the push rod is slidably connected to the sleeve. A number of ball springs are provided radially around the inner arc surface of the sleeve. A claw spring is provided between the push rod body and the sleeve.

[0004] Furthermore, the lifting mechanism includes a lifting cylinder, which is installed on the bottom surface of the top plate. The vertical channel opened inside the lifting cylinder is directly opposite the lifting hole. The inner wall of the vertical channel is slidably connected to the limiting plate in the middle of the lifting column. The lower end of the lifting column is inserted into the lifting spring, which is located between the limiting plate and the bottom surface of the vertical channel.

[0005] Furthermore, the sensing component includes a sensing base, which is installed in a recessed groove on the top surface of the top plate. The recessed groove is located between adjacent lifting holes. The sensing base has two photoelectric probes built in it, and the two photoelectric probes are respectively facing the adjacent lifting column. Each photoelectric probe is connected to a series circuit, and the series circuit is electrically connected to the alarm device.

[0006] Furthermore, the sleeve neck ring is provided with a stroke rod, which is slidably connected to the vertical waist hole opened in the top rod body. The inner arc surface of the sleeve base is provided with two layers of threaded through holes, with the upper and lower layers of threaded through holes arranged alternately, and the threaded through holes are threadedly connected to the ball springs.

[0007] Furthermore, the push rod has an air blowing channel at its center, the upper end of which is connected to an air passage, and the lower end of which passes through a circumferential branch pipe to the outer surface of the push rod.

[0008] The beneficial effects of this utility model are as follows: This utility model identifies the copper sleeve placed on the lifting column through the sensing component. When the worker misplaces or misses the copper sleeve, the photoelectric probe cannot sense the part, the series circuit short-circuits, and thus an alarm is issued, avoiding human error in the assembly process; the gripper in the tooling can grip and install the copper sleeve under the control of the robot arm, and can remove scattered debris through the air blowing channel. It has the characteristics of being automatic and controllable, and is suitable for mechanized production and precision installation of equipment. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] As shown in Figures 1 to 5, a copper sleeve anti-misalignment fixture includes a fixed base 1. The top plate 101 of the fixed base 1 has a plurality of lifting holes 102 in the center ring. The diameter of the lifting holes 102 is smaller than the outer diameter of the copper sleeve 3 to be installed. The lifting holes 102 are vertically slidably connected to the lifting column 2. The lifting column 2 passes through the lifting holes 102 through the lifting mechanism and is inserted into the copper sleeve 3. The lifting mechanism includes a lifting cylinder 8, which is installed on the bottom surface of the top plate 101. The vertical channel 801 opened in the lifting cylinder 8 is directly opposite to the lifting holes 102. The inner wall of the vertical channel 801 is slidably connected to the limiting plate 201 in the middle of the column body of the lifting column 2. The lower end of the lifting column 2 is inserted into the lifting spring 9, which is located between the limiting plate 201 and the bottom surface of the vertical channel 801. A sensing component is provided between adjacent lifting holes 102. The sensing component includes a sensing base 10. The sensing base 10 is installed in the recess 103 on the top surface of the top plate 101. The recess 103 is located between adjacent lifting holes 102. The sensing base 10 has two photoelectric probes 11 built in it. The two photoelectric probes 11 are respectively facing the adjacent lifting column 2. Each photoelectric probe 11 is connected to a series circuit. The series circuit is electrically connected to an alarm device.

[0019] In this embodiment, the inner diameter of the copper sleeve 3 is clearance-fitted with the outer diameter of the push rod 4 in the sleeve clamp. The push rod 4 has an air blowing channel 402 at its center. The upper end of the air blowing channel 402 is connected to an air passage, and the lower end of the air blowing channel 402 passes through the outer surface of the push rod 4 through a circumferential branch pipe. The lower end of the push rod 4 is slidably connected to the clamp 5. The neck ring of the clamp 5 is provided with a stroke rod 501. The stroke rod 501 is slidably connected to the vertical waist hole 401 opened in the push rod 4. The inner arc surface of the clamp 5 base is radially provided with two layers of threaded through holes 502. The upper and lower layers of threaded through holes 502 are arranged at intervals. The threaded through holes 502 are threadedly connected to ball springs 6. The steel balls of the ball springs 6 pass through the inner arc surface of the clamp 5. A clamp spring 7 is provided between the push rod 4 body and the top surface of the neck of the clamp 5.

[0020] The working principle of this utility model is as follows:

[0021] The copper sleeves 3 are placed sequentially onto each lifting column 2 for positioning. The photoelectric probe 11 detects the copper sleeves 3. When a copper sleeve 3 is misplaced or missing, the photoelectric probe 11 cannot detect the correct part, the circuit connected in series with the photoelectric probe 11 is de-energized, and the alarm device issues a self-test alarm. After all the copper sleeves 3 are correctly positioned, the robotic arm moves the gripper directly above the copper sleeve 3 and the gripper descends to pick up the copper sleeve 3. As shown in Figure 4, during the descent, the airflow from the robotic arm's air passage continuously blows out from the air blowing channel 402. The push rod 4 pushes the lifting column 2 downward against the elastic force of the lifting spring 9. When the bottom surface of the clamp 5 plate contacts the top surface of the sensing seat 10, the copper sleeve 3 is completely embedded in the gap between the push rod 4 and the clamp 5, and the steel balls in the ball spring 6 press against the outer wall of the copper sleeve 3. Subsequently, the gripper moves the copper sleeve 3 upward and horizontally above the workpiece to be assembled, driven by the robot arm. The gripper then moves downward again, as shown in Figure 5. When the bottom surface of the sleeve 5 contacts the top surface of the workpiece, the robot arm continues to push the push rod 4 downward against the gripper spring 7, pressing the copper sleeve 3 into the cavity of the workpiece. The pressing depth can be precisely adjusted according to the downward pressure of the robot arm.

[0022] This invention uses a sensing component to identify the copper sleeve 3 placed on the lifting column 2, preventing workers from misplacing or omitting it, thus avoiding human error during assembly. The grippers in the tooling can clamp and install the copper sleeve 3 under the control of the robotic arm, which is automatic and controllable, and is suitable for mechanized production and precision installation of equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
