Description

Technical Field

[0001] This utility model belongs to the field of motor processing technology, and specifically relates to a tooling for inserting cylindrical pins into the stator plate of a push-button linear motor. Background Technology

[0002] Linear motors are currently widely used in industrial automation, medical equipment, aerospace, and smart homes. The structure of a linear motor consists of a mover and a stator, with the stator being the primary source of the magnetic field. The stator comprises a stator plate, magnets, and cylindrical pins. The magnets are positioned using the cylindrical pins and are glued to the surface of the stator plate. The cylindrical pins prevent magnet displacement, which could affect electromagnetic performance and appearance.

[0003] like Figure 1 As shown, currently, the insertion of cylindrical pins 12 into the stator plate 10 of a linear motor is mainly done manually. The stator plate 1 has multiple cylindrical pin holes 11, each requiring the insertion of cylindrical pins 12. Existing methods for installing cylindrical pins into the linear motor stator plate have the following problems: 1. Due to the small diameter and short length of the cylindrical pins used on the stator plate, manual insertion requires high levels of concentration, eyesight, and finger dexterity from the operator. During prolonged work, operators are prone to fatigue, eye strain, finger pain, and reduced work efficiency. 2. Currently, there are no auxiliary fixtures for inserting cylindrical pins into the linear motor stator plate. Utility Model Content

[0004] This invention provides a tooling for inserting cylindrical pins into the stator plate of a push-button linear motor, which can solve the problems existing in the prior art.

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0006] This utility model embodiment provides a tooling for inserting cylindrical pins into the stator plate of a push-button linear motor, including a cylindrical pin storage chamber (1), a channel tube (2), a spring (3), a chuck (4), a claw (5), and a guard (6); the cylindrical pin storage chamber (1) is connected to the channel tube (2) through a first groove on its inner surface; the chuck (4) includes a ring structure (4-1) and a second spring limiting post (4-3) located inside the ring structure (4-1), the ring structure (4-1) is provided with a second groove (4-2) on the side facing the guard (6), and the ring structure (4-1) is connected to the channel tube (2) through a first groove on its inner surface; A third slot (4-4) is formed between the second spring limiting posts (4-3); one end of the spring (3) is connected to the first slot of the cylindrical pin storage chamber (1), and the other end is connected to the third slot (4-4) of the chuck (4); the top of the claw (6) is provided with a plurality of toothed structures (6-1), a fourth slot (6-2) is provided between the plurality of toothed structures (6-1), and the plurality of toothed structures (6-1) are connected to the second slot (4-2); the flower claw (5) includes a plurality of petal-shaped structures (5-1), and the petal-shaped structures (5-1) are placed in the fourth slot (6-2);

[0007] Before inserting the cylindrical pin (12) into the stator plate (10), the cylindrical pin (12) is inserted into the cylindrical pin storage chamber (1). At this time, the cylindrical pin (12) falls into the channel tube (2) along the cylindrical pin storage chamber (1). Align the claw (6) with the cylindrical pin hole (11) on the stator plate (10), place the thumb and forefinger on the boss (1-1) of the cylindrical pin storage chamber (1), and press down until the first spring limiting post on the cylindrical pin storage chamber (1) and the second spring limiting post (4-3) on the chuck (4) come into contact. The spring (3) is in a compressed state. During this process, the channel tube (2) moves downward with the cylindrical pin storage chamber (1). When the channel tube (2) contacts the claw (5), the claw (5) changes from a closed state to an open state due to the downward force. At this time, the cylindrical pin (12) in the channel tube (2) falls into the cylindrical pin hole (11) on the stator plate (10). When the spring (3) rebounds, the claw (5) slowly closes as the force decreases. The first spring limiting post on the cylindrical pin storage chamber (1) and the second spring limiting post (4-3) on the chuck (4) gradually move away from each other, and the cylindrical pin (12) can no longer fall. Each time the cylindrical pin storage chamber (1) is pressed down, a cylindrical pin (12) falls into a cylindrical pin hole (11).

[0008] In one optional embodiment of this utility model, the second slot (4-2) is a groove that fits into the convex tooth structure (6-1).

[0009] In one optional embodiment of this utility model, a through hole is provided inside the second spring limiting post (4-3).

[0010] Compared with the prior art, this utility model provides a tooling for inserting cylindrical pins into the stator plate of a push-button linear motor, which has the following advantages: (1) With the tooling of this utility model, inserting cylindrical pins into the stator plate no longer requires high attention, vision, and finger dexterity from the operator, thus reducing the labor intensity of the operator. (2) The entire tooling has a simple structure and is easy to operate. (3) Through the cooperation of the spring with the cylindrical pin storage chamber, the channel tube, the chuck, and the claw, each time the operator presses down on the cylindrical pin storage chamber, a cylindrical pin will fall down. (4) The entire tooling does not require screw connection; it is connected by the transition fit of the slot and the tooth. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this utility model embodiment provides a tooling for inserting cylindrical pins into the stator plate of a push-button linear motor, including a cylindrical pin storage chamber 1, a channel tube 2, a spring 3, a chuck 4, a claw 5, and a guard 6. The cylindrical pin storage chamber 1 is connected to the channel tube 2 through a first groove on its inner surface. The spring 3 is used to connect the cylindrical pin storage chamber 1 and the chuck 4. The claw 5 is placed in a fourth groove on the guard 6. The guard 6 and the chuck 4 are connected through a toothed structure 6-1 on the guard 6 and a second groove 4-2 on the chuck 4.

[0020] Specifically, the chuck 4 includes a circular ring structure 4-1 and a second spring limiting post 4-3 located inside the circular ring structure 4-1. A second groove 4-2 is provided on the side of the circular ring structure 4-1 facing the claw 6, and a third groove 4-4 is formed between the circular ring structure 4-1 and the second spring limiting post 4-3. One end of the spring 3 is connected to the first groove of the cylindrical pin storage chamber 1, and the other end is connected to the third groove 4-4 of the chuck 4. The claw 6 has multiple toothed structures 6-1 on its top, and a fourth groove 6-2 is provided between the multiple toothed structures 6-1, with the multiple toothed structures 6-1 connected to the second groove 4-2. The claw 5 includes multiple petal-shaped structures 5-1, which are placed in the fourth groove 6-2. Preferably, the second groove 4-2 is a recess that fits into the toothed structures 6-1. A through hole is provided inside the second spring limiting post 4-3.

[0021] like Figures 1-6As shown, before inserting the cylindrical pin 12 into the stator plate 10, the cylindrical pin 12 is inserted into the cylindrical pin storage chamber 1. At this time, the cylindrical pin 12 falls into the channel tube 2 along the cylindrical pin storage chamber 1. The guard 6 is aligned with the cylindrical pin hole 11 on the stator plate 10, and the thumb and forefinger are placed on the boss 1-1 of the cylindrical pin storage chamber 1. The pressure is pressed down until the first spring limiting post on the cylindrical pin storage chamber 1 and the second spring limiting post 4-3 on the chuck 4 come into contact. The spring 3 is in a compressed state. During this process, the channel tube 2 moves downward with the cylindrical pin storage chamber 1. When the channel tube 2 contacts the claw 5, the claw 5 changes from a closed state to an open state due to the downward force. At this time, the cylindrical pin 12 in the channel tube 2 falls into the cylindrical pin hole 11 on the stator plate 10. When the spring 3 rebounds, the claw 5 slowly closes as the force decreases. The first spring limiting post on the cylindrical pin storage chamber 1 and the second spring limiting post 4-3 on the chuck 4 gradually move away from each other, and the cylindrical pin 12 can no longer fall. Each time the cylindrical pin storage chamber 1 is pressed down, a cylindrical pin 12 falls into a cylindrical pin hole 11.

[0022] In this embodiment, the number of cylindrical pins falling into the cylindrical pin holes is adjusted by a spring, a claw, and a limiting post, thus controlling the number of cylindrical pins falling into the holes. The structure is simple. The entire tooling is connected by a transition fit between a slot and a boss, and the petal-shaped structure of the claw is connected to the guard claw.

[0023] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
