Description

Technical Field

[0001] This utility model relates to the field of spindle production and processing equipment, specifically to an automatic screw alignment mechanism for spindle assembly. Background Technology

[0002] Spindles are key equipment components used in the textile industry for processes such as spinning and winding. Spindles are mainly used to support yarn tubes (yarn packages) and control yarn tension, thereby ensuring the smooth operation of the yarn during unwinding or winding.

[0003] The pendant mainly consists of a main support frame, pins, pendant cap, screw, nut, and other components. During processing, the pendant cap and screw need to be assembled together at a specified angle, and the nut needs to be locked onto the screw. The screw has anti-foolproof protrusions, and the pendant cap has grooves corresponding to the anti-foolproof protrusions. Existing assembly equipment requires manual alignment of the pendant cap and screw before the automated locking of the nut can be performed, so production efficiency and quality still need to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic screw alignment mechanism for assembling hanging spindles, which can adapt to the fully automatic alignment and assembly of the hanging spindle cap and screw and the feeding and locking of the nut, thereby improving the production efficiency and quality of hanging spindles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic screw alignment mechanism for assembling a lifting spindle, comprising an XYZ moving component, a bracket, a positioning seat, and a loading robot. A base plate is fixedly connected to the moving platform of the XYZ moving component. A first gripper cylinder and a second gripper cylinder are fixedly connected to the upper and lower sides of the base plate. A lifting cylinder is fixedly connected to the bracket. A first motor is fixedly connected to the slide of the lifting cylinder. A pneumatic gripper is fixedly connected to the rotating shaft of the first motor. A second motor is fixedly connected to the output end of the loading robot. A nut collet is fixedly connected to the output end of the second motor.

[0006] Furthermore, the bracket and the loading robot are located on both sides of the XYZ moving assembly, and the positioning seat is provided with a positioning groove.

[0007] Furthermore, a first contouring clamping plate is detachably connected to the two jaws of the first gripper cylinder, and a second contouring clamping plate is detachably connected to the two jaws of the second gripper cylinder.

[0008] Furthermore, light-shielding plates are fixedly connected to the base of the pneumatic gripper and the nut collet, and photoelectric sensors are fixedly connected to the slide of the lifting cylinder and the slide of the loading robot.

[0009] Furthermore, the nut collet includes a collet body, the bottom of which is provided with a hexagonal groove, and collet plates are hinged to both sides of the hexagonal groove on the collet body. A torsion spring is provided at the connection between the collet plates and the collet body.

[0010] Furthermore, a silicone tube is fitted onto the collet body, and the collet plate is in contact with the inner wall of the silicone tube.

[0011] The beneficial effects of this utility model are as follows: by using the XYZ moving component, the first gripper cylinder, the second gripper cylinder in conjunction with the first motor and the pneumatic gripper, it is possible to rotate the screw while the lifting cap is pressed down so that the protrusion of the screw matches the groove of the lifting cap to achieve alignment.

[0012] By using a robotic arm, a second motor, and a nut clamp, the nut can be automatically attached to the screw and the lifting cap, improving the production efficiency and quality of the lifting load. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] refer to Figures 1-4The automatic alignment mechanism for screw assembly shown includes an XYZ moving component 1, a support 2, a positioning seat 6, and a loading robot 7. A base plate 3 is fixedly connected to the moving platform of the XYZ moving component 1. A first gripper cylinder 4 and a second gripper cylinder 5 are fixedly connected to the upper and lower sides of the base plate 3. A lifting cylinder 201 is fixedly connected to the support 2. A first motor 202 is fixedly connected to the slide of the lifting cylinder 201. A pneumatic gripper 203 is fixedly connected to the rotating shaft of the first motor 202. A second motor 701 is fixedly connected to the output end of the loading robot 7. A nut collet 9 is fixedly connected to the output end of the second motor 701.

[0020] In one embodiment of this solution, the support 2 and the loading robot 7 are located on both sides of the XYZ moving assembly 1, and the positioning seat 6 is provided with a positioning groove for positioning and placing the main support pre-installed with the lifting cap and screw, as can be seen from the following. Figure 1 The positioning seat has 6 structural features.

[0021] In one embodiment of this solution, a first contouring clamping plate 401 is detachably connected to the two jaws of the first jaw cylinder 4. The first contouring clamping plate 401 can be replaced according to actual processing needs. A second contouring clamping plate 502 is detachably connected to the two jaws of the second jaw cylinder 5. The second contouring clamping plate 502 can be replaced according to actual processing needs. The contouring structure is used to improve the clamping effect.

[0022] In one embodiment of this solution, a light-shielding plate 204 is fixedly connected to the base of the pneumatic gripper 203 and the nut collet 9. A photoelectric sensor 205 is fixedly connected to both the slide of the lifting cylinder 201 and the slide of the loading robot 7. The light-shielding plate 204 is used to cooperate with the photoelectric sensor 205 for angle positioning.

[0023] In one embodiment of this solution, a hexagonal groove at the bottom of the collet body 901 is used to position and load the nut. Collet plates 902 on both sides of the hexagonal groove are used to clamp the nut after it has been placed. A torsion spring is provided at the connection between the collet plates 902 and the collet body 901. The silicone tube 8 fitted on the collet body 901 can further improve the clamping effect of the collet plates 902 on the nut. The silicone collet plates 902 are in close contact with the inner wall of the silicone tube 8.

[0024] The working principle of this utility model is as follows: The positioning seat 6 can be fixed on the external circulating conveyor line for conveying. When the semi-finished product to be processed, the ingot, arrives at the screw alignment station, the XYZ moving component 1 first drives the first gripper cylinder and the second gripper cylinder 5 to the screw alignment station. The first gripper cylinder and the second gripper cylinder 5 clamp the ingot cap and press it down. At the same time, the piston rod of the lifting cylinder 201 extends, and the pneumatic gripper 203 descends to clamp the screw. Then, the first motor 202 drives the pneumatic gripper 203 to rotate. During the rotation of the screw, when the groove of the ingot cap matches the protrusion on the screw... After the angle is adjusted, under the action of downward pressure, the lifting cap will descend relative to the screw to complete the alignment and assembly. Then, the positioning seat 6 will move to the nut locking station, where the external feeding mechanism will feed the nut into the positioning groove on the collet body 901. Under the action of the silicone tube 8 and the torsion spring, the collet plate 902 will clamp the nut. Then, the feeding robot 7 will transfer the nut to the top of the screw and lower it vertically. During the descent, the second motor 701 will drive the nut collet 9 to rotate, thereby locking the nut onto the screw (the collet body 901 has a clearance hole corresponding to the screw to avoid interference during the nut locking and descent).

[0025] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
