Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This embodiment provides a special tooling for adding pins to shaft-shaped workpieces, used to add pins 20 to shaft-shaped workpieces 10.

[0024] Please see Figure 1 In this embodiment, the shaft-shaped workpiece 10 is the rotating shaft of the motor 30 (especially the brushless DC motor). The shaft-shaped workpiece 10 is provided with a plug hole 10a suitable for inserting the pin 20. In fact, the plug hole 10a is a circular hole opened in the radial direction on the shaft-shaped workpiece 10.

[0025] It should be noted that the pin 20 is a metal pin-shaped workpiece, which can be hollow to provide a certain deformation, so that the pin 20 can easily be interference-fitted with the insertion hole 10a of the shaft-shaped workpiece 10.

[0026] Please see Figure 2 and Figure 3 The special tooling for attaching pins to shaft-shaped workpieces includes a tooling fixture 40 and a pressing device 50.

[0027] The tooling fixture 40 includes a support base 40a, which is actually a metal base.

[0028] A shaft-shaped workpiece insertion hole 40b is provided at the support base 40a along the first direction. The shaft-shaped workpiece insertion hole 40b is suitable for inserting the shaft-shaped workpiece 10 into it along the first direction. That is, the shaft-shaped workpiece insertion hole 40b is a circular hole that matches the shape of the shaft-shaped workpiece 10 and can be obtained by machining.

[0029] The support base 40a is also provided with a pin placement groove 40c along the second direction, which communicates with the shaft-shaped workpiece insertion hole 40b. The pin placement groove 40c is suitable for the pin 20 to be inserted into it along the second direction / first direction. Furthermore, the pin 20 can also be withdrawn from the pin placement groove 40c along the first direction. That is, the pin placement groove 40c is a square groove that passes through the two mutually perpendicular sides of the support base 40a and communicates with the shaft-shaped workpiece insertion hole 40b. The pin placement groove 40c can also be obtained by machining.

[0030] The pressing device 50 is equipped with a pressing shaft 50a that can move horizontally.

[0031] The pressing shaft 50a of the pressing device 50 can move in the direction of the pin placement groove 40c to press the pin 20 into the insertion hole 10a of the shaft workpiece 10.

[0032] Specifically, the first direction is horizontal and the second direction is vertical; or, the first direction is vertical and the second direction is horizontal.

[0033] In this embodiment, the first direction is horizontal and the second direction is vertical; the pressing device 50 is supported above the pin placement groove 40c of the tooling fixture 40 by a bracket, and the pressing shaft 50a of the pressing device 50 is arranged along the second direction.

[0034] Furthermore, the special tooling for attaching pins to shaft-shaped workpieces in this embodiment also includes an interactive device 60, which is used to control the operating state of the pressing device 50; when the interactive device 60 is triggered, the pressing shaft 50a of the pressing device 50 translates in the direction of the pin placement groove 40c; when the interactive device 60 is triggered again, or after a time delay, the pressing shaft 50a of the pressing device 50 retracts.

[0035] Specifically, the pressing device 50 is any of the following: a cylinder, an electric cylinder, a linear slide rail, or a telescopic shaft motor.

[0036] In this embodiment, the pressing device 50 is a cylinder, which has an extension port and a retraction port. When compressed gas is introduced into the extension port, the pressing shaft 50a extends; when compressed gas is introduced into the retraction port, the pressing shaft 50a retracts. A solenoid valve is configured between the pressing device 50 and the air source. Specifically, this solenoid valve is a dual-way single-pass solenoid valve. One path of the solenoid valve is connected between the extension port of the pressing device 50 and the air source, and the other path of the solenoid valve is connected between the retraction port of the pressing device 50 and the air source. Interaction device 60 is a switch, specifically a push-button mechanical switch; interaction device 60 is electrically connected and / or signal connected to the solenoid valve (specifically, it can be directly connected through a signal wire, or indirectly connected through a main control device such as a PLC). Pressing interaction device 60 can switch the solenoid valve's path state (i.e., switch the solenoid valve's dual-path on / off state), thereby switching the operating state of pressing device 50 (i.e., pressing shaft 50a moves horizontally towards pin placement groove 40c, or pressing shaft 50a retracts).

[0037] In this embodiment, a special tooling for attaching pins to the shaft-shaped workpiece is used, following these steps:

[0038] S1, such as Figure 4 As shown, the shaft-shaped workpiece 10 is inserted into the shaft-shaped workpiece insertion hole 40b of the tooling fixture 40 along the first direction (i.e., the horizontal direction), and the insertion hole 10a of the shaft-shaped workpiece 10 is aligned with the pin placement groove 40c of the tooling fixture 40; then, the pin 20 is inserted into the pin placement groove 40c of the tooling fixture 40 along the second direction / first direction; after this step, the relative positions of the tooling fixture 40, the shaft-shaped workpiece 10, and the pin 20 are as follows. Figure 5 As shown;

[0039] S2. Press the interactive device 60 to switch the solenoid valve's access state, allowing compressed gas to be supplied from the air source to the extended interface of the pressing device 50. At this time, the pressing shaft 50a of the pressing device 50 moves in the direction of the pin placement groove 40c, applying axial force to the pin 20 to press the pin 20 into the insertion hole 10a of the shaft-shaped workpiece 10. Subsequently, press the interactive device 60 again, or after a time delay, the solenoid valve's access state is switched, allowing compressed gas to be supplied from the air source to the retraction interface of the pressing device 50. At this time, the pressing shaft 50a of the pressing device 50 retracts.

[0040] S3, such as Figure 6 As shown, the assembly of the shaft-shaped workpiece 10 and the pin 20 is removed from the shaft-shaped workpiece insertion hole 40b and the pin placement groove 40c of the tooling fixture 40 along the first direction; thus, the process of installing the pin 20 at the shaft-shaped workpiece 10 is completed.

[0041] In this embodiment, a special tooling for attaching a pin to a shaft-shaped workpiece is provided. The support base 40a has a shaft-shaped workpiece insertion hole 40b along the first direction, and the support base 40a also has a pin placement groove 40c along the second direction that connects to the shaft-shaped workpiece insertion hole 40b. The pressing shaft 50a of the pressing device 50 can move in the direction of the pin placement groove 40c to press the pin 20 into the insertion hole 10a of the shaft-shaped workpiece 10. This allows for the quick and efficient completion of the process of attaching the pin 20 to the shaft-shaped workpiece 10, saving labor costs in the motor assembly process and improving the efficiency and yield of motor assembly.
