Description

Technical Field

[0001] The utility model relates to the technical field of servo motor processing, in particular to a device for installing a servo motor rotor. Background Art

[0002] When a servo motor is produced, the stator and rotor of the servo motor need to be assembled, but the fitting clearance between the stator and the rotor is very small. The stator is an iron silicon steel sheet, and the rotor is affixed with a permanent magnet with strong magnetism. When the rotor is manually placed into the stator, a strong suction force is generated, causing the rotor to rush toward the stator quickly, causing a collision and causing damage to the stator and rotor. Utility Model Content

[0003] The purpose of the utility model is to provide a device for installing a servo motor rotor to overcome the above-mentioned defects in the prior art.

[0004] A device for installing a servo motor rotor comprises a workbench, a clamping mechanism and an assembly mechanism, wherein the workbench is provided with a positioning seat for placing a casing, the clamping mechanism is arranged on the workbench and used to fix the casing, and the assembly mechanism is arranged on the workbench and used to assemble the rotor into the stator of the casing.

[0005] Preferably, the clamping mechanism comprises a double-axis cylinder, a connecting plate and clamping claws, and two piston rods on the same side of the double-axis cylinder are connected to the same connecting plate, and a clamping claw is provided on the inner side of each connecting plate.

[0006] Preferably, a soft patch is provided on the inner side of the clamping jaw.

[0007] Preferably, the assembly mechanism includes a servo electric cylinder, a linear bearing and a guide rod, the servo electric cylinder is installed on a support at the bottom of the workbench, the linear bearing is installed on the workbench in the positioning seat and its lower end is inserted into the support, the guide rod is installed on the cylinder rod of the servo electric cylinder and inserted into the linear bearing and the positioning seat, and the guide rod is provided with an inner hole for inserting the shaft end of the rotor.

[0008] Preferably, the positioning seat is connected to the workbench by screws.

[0009] The utility model has the following advantages:

[0010] When the utility model is in use, the casing is clamped and fixed by the double-axis cylinder of the clamping mechanism and the clamping claws thereon, and then the rotor is transferred to the stator in the casing by the guide rod of the servo electric cylinder of the assembly mechanism. Since the guide rod is inserted in the linear bearing, the rotor will not produce any swing in the downward process even if there is strong magnetic interference, thereby improving the assembly quality of the servo motor, and after the transfer, the assembled stator and rotor are pushed out from the positioning seat again by the guide rod, which is convenient for workers to remove.

DETAILED DESCRIPTION

[0016] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0017] like Figure 1-4 As shown, the utility model provides a device for installing a servo motor rotor 51, including a workbench 1, a clamping mechanism 3 and an assembly mechanism 4. The workbench 1 is provided with a positioning seat 2 for placing a housing 5, and the positioning seat 2 is connected to the workbench 1 by screws, so as to facilitate the disassembly and assembly of the positioning seat 2. The clamping mechanism 3 is arranged on the workbench 1 and used to fix the housing 5. The assembly mechanism 4 is arranged on the workbench 1 and used to assemble the rotor 51 into the stator 52 of the housing 5.

[0018] It should be noted that the clamping mechanism 3 includes a double-axis cylinder 31, a connecting plate 32 and a clamping claw 33. The two piston rods on the same side of the double-axis cylinder 31 are connected to the same connecting plate 32. A clamping claw 33 is provided on the inner side of each connecting plate 32. A soft patch 34 is provided on the inner side of the clamping claw 33 to prevent the clamping claw 33 from causing damage to the casing 5 when clamping it.

[0019] In addition, the assembly mechanism 4 includes a servo electric cylinder 41, a linear bearing 43 and a guide rod 44. The servo electric cylinder 41 is installed on a support 42 at the bottom of the workbench 1. The linear bearing 43 is installed on the workbench 1 in the positioning seat 2 and its lower end is inserted into the support 42. The guide rod 44 is installed on the cylinder rod of the servo electric cylinder 41 and is inserted into the linear bearing 43 and the positioning seat 2. The guide rod 44 is guided by the linear bearing 43, and the guide rod 44 is provided with an inner hole for inserting the shaft end of the rotor 51.

[0020] Specific implementation and principle:

[0021] In the initial state, the piston rod of the double-axis cylinder 31 drives the connecting plate 32 and the clamping claw 33 to extend outward, and at this time they are in a loose state, and the cylinder rod of the servo electric cylinder 41 drives the guide rod 44 to extend upward, and at this time they are in a predetermined high position; the housing 5 equipped with the stator 52 is manually placed into the positioning groove of the positioning seat 2, and the shaft end of the rotor 51 is inserted into the inner hole of the guide rod 44; then the piston rod of the double-axis cylinder 31 is controlled to retract, and the clamping claws 33 on both sides move toward the housing 5 to tightly clamp the housing 5, and then the guide rod 44 on the cylinder body of the servo electric cylinder 41 is controlled to drive the rotor 5 1 continuously moves downward. Since the guide rod 44 is inserted in the linear bearing 43, the rotor 51 will not swing in the downward process even if there is strong magnetic interference. The cylinder rod of the servo electric cylinder 41 retracts to a predetermined position, and the rotor 51 and the stator 52 are attracted together. At this time, the double-axis cylinder 31 drives the connecting plate 32 and the clamping claw 33 to extend outward, and is in a loose state. The cylinder rod of the servo electric cylinder 41 extends, driving the guide rod 44 to move upward, and the attracted stator and rotor 51 are pushed out together, and the attracted stator and rotor 51 are manually removed.

[0022] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
