Abstract
Description
Technical Field
[0001] This application relates to the field of motor technology, for example to a motor quick-change structure. Background Technology
[0002] As a power output mechanism, the motor's output end is connected to the interface of the driven component (a device component that relies on the motor's output to achieve movement), thereby transmitting the motor's output to the driven component. Generally, the motor's output shaft is directly connected to the external driven component. The motor is usually positioned along the axial direction of the driven component. Therefore, when setting up the driven component, a motor mounting position needs to be reserved along its axial direction. This greatly limits the installation position of the driven component, especially in certain environments, such as glove boxes, where space is limited, restricting the installation position of the driven component, greatly reducing the flexibility of the installation position, and making it difficult to achieve a reasonable layout.
[0003] In implementing the embodiments of this disclosure, it has been found that at least the following problems exist in the related art: the installation position of existing driven components is limited, and the installation flexibility is low. Summary of the Invention
[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.
[0005] This disclosure provides a quick-change structure for a motor to solve the problem of limited installation position and low installation flexibility of existing driven components.
[0006] In some embodiments, the motor quick-change structure, used at the motor end, includes: a base plate; a transmission mechanism movably mounted on the base plate, the first end of which can be connected to the output end of the motor, and the second end of which is provided with an output structure, the output structure including a shaft hole or an output shaft, for connecting with a driven component, thereby translating the output of the motor; a first connection structure including a first locking structure, the first locking structure being disposed on the base plate for positioning and connecting with the driven component; wherein, the first locking structure includes a locking pin; the locking end of the locking pin protrudes from the side of the base plate connected to the driven component; the locking pin includes: a pin shaft, with a shaft hole provided axially, and a pin being provided on its side wall. It has a locking port; a mandrel, movably disposed within the shaft hole of the pin, and having a receiving groove on its side wall; a locking structure disposed within the locking port; the mandrel is axially movable, allowing the locking structure to switch between an unlocked state and a locked state; a damping structure disposed between the pin and the mandrel, limiting the relative displacement between the pin and the mandrel; and a handle disposed on the pin; wherein, when the receiving groove of the mandrel coincides with the locking hole of the pin, the locking structure is in an unlocked state; when the side wall of the mandrel is opposite to the locking hole of the pin, the locking structure is in a locked state and partially protrudes from the outer side wall of the pin.
[0007] In some embodiments, the motor quick-change structure, for the driven end, includes: an input structure that can be connected to the second end of the transmission mechanism in the aforementioned motor quick-change structure; and a second connection structure that cooperates with the first connection structure in the aforementioned motor quick-change structure for positioning and connection with the motor.
[0008] The quick-change structure for motors provided in this disclosure can achieve the following technical effects:
[0009] The quick-change structure for motors in this embodiment utilizes a transmission mechanism to translate the motor's output. Therefore, the motor does not necessarily need to be positioned axially on the driven component, allowing it to be moved to the side of the driven component. Thus, only space is needed axially on the driven component to accommodate the quick-change structure, eliminating the axial space limitations on driven component installation. Motor removal and replacement are also easier. It is suitable for specific environments such as glove boxes. Furthermore, the quick-change structure integrates the transmission mechanism and the first connecting structure onto a base plate, forming a single module. This facilitates connection and removal of the quick-change structure, simplifying operation. Moreover, it features a simple structure, high efficiency, strong versatility, and no impact on other operations within glove boxes or other special environments.

[0036] Combination Figure 1-13 As shown, this embodiment of the present disclosure provides a quick-change structure for a motor 10, including a base plate 11, a transmission mechanism 12, and a first connecting structure. The transmission mechanism 12 is movably mounted on the base plate 11, with its first end 121 connected to the output end of the motor, and its second end 122 having an output structure 123 for connecting to a driven component 20, thereby translating the output of the motor 10. The first connecting structure is mounted on the base plate 11 and is used for positioning and connecting with the driven component 20.
[0037] The quick-change structure for motors in this embodiment utilizes the transmission mechanism 12 to translate the output of the motor 10. Therefore, the motor does not necessarily need to be positioned axially on the driven component 20, allowing it to be moved to the side of the driven component 20. Thus, only space is needed axially on the driven component 20 to accommodate the quick-change structure, eliminating the limitation of axial dimensions on the installation of the driven component 20. This also facilitates the removal and replacement of the motor. It is suitable for specific environments such as glove boxes. Furthermore, the quick-change structure integrates the transmission mechanism 12 and the first connecting structure onto the base plate 11, forming an independent module, which facilitates the connection and removal of the quick-change structure and makes operation convenient.

In this embodiment, the length of the transmission member 124 can be adjusted according to actual needs, and the output speed of the motor 10 can also be adjusted by adjusting the different transmission ratios of the first end 121 and the second end 122.

For example, a second gear with a shaft hole, a second pulley with a shaft hole; or a second gear with a shaft, a second pulley with a shaft, etc. The output speed of the motor 10 is adjusted by adjusting the size or gear ratio on the first and second rotating members.
[0044] Optionally, the transmission component 124 may be a conveyor belt or a conveyor rack.

[0049] Optionally, the second end 122 (the second gear or the second pulley) is rotatably disposed on the second through hole.

That is, the first positioning structure 13 is coaxially disposed with the output structure 123 of the second end 122 of the transmission mechanism 12, so that the positioning is accurate.
[0053] In this embodiment, the specific shape of the first positioning structure 13 is not limited, as long as it is a structure capable of positioning. Optionally, the first positioning structure 13 includes a positioning boss and / or a positioning hole. Optionally, as...

[0054] Optionally, the first locking structure 14 includes a locking pin; the locking end 141 of the locking pin protrudes from the side of the base plate 11 that connects to the driven assembly 20, so as to extend into the motor quick-change structure provided at the driven end to achieve connection.

[0061] In some embodiments, the input structure 21 includes an input shaft or an input shaft hole. The specific form of the output structure 123 is determined based on the configuration of the second end 122 of the transmission mechanism 12.
[0062] Optionally, if the output structure 123 includes an output shaft hole, then the input structure 21 includes an input shaft. Optionally, the output shaft hole at the motor end is a hexagonal hole, and the input structure 21 at the driven end is a hexagonal shaft.

Optionally, the second positioning structure 22 is a positioning hole, which is coaxially arranged with the input structure 21 for precise positioning.
[0065] Optionally, the second locking structure 23 is a locking sleeve. The inner wall of the locking sleeve is provided with a locking platform structure, which cooperates with the locking structure of the locking end 141 of the aforementioned first locking structure 14 to achieve locking.
[0066] In this embodiment of the disclosure, combined with Figures 5 to 14 The diagram illustrates a specific spring-locking pin structure that can be used in the quick-change motor structure of this embodiment. The spring-locking pin 30 includes a pin 31, a spindle 32, a locking structure 33, and a damping structure 36. The pin 31 has an axial hole 311 and a locking opening 312 on its sidewall. The spindle 32 is movably disposed within the pin hole 311 and has a receiving groove 321 on its sidewall. The locking structure 33 is disposed within the locking opening 312, and the spindle 32 can move axially, allowing the locking structure 33 to switch between an unlocked and locked state. The damping structure 36 is disposed between the pin 31 and the spindle 32, limiting the relative displacement between them. When the receiving groove 321 of the spindle 32 coincides with the locking port 312 of the pin 31, the locking structure 33 is in the unlocked state; when the side wall of the spindle 32 is opposite to the locking port 312 of the pin 31, the locking structure 33 is in the locked state and partially protrudes from the outer side wall of the pin 31. Furthermore, when the locking structure 33 is in the locked state, the side wall portion of the locking structure 33 that contacts the spindle 32 is inclined, serving as an ejection inclined surface 320. The pin 31 is fixedly mounted on the base plate 11, with the locking end protruding from the side of the base plate 11 connected to the driven assembly 20.
[0067] The spring locking pin of this embodiment splits the locking pin structure into two parts: a spindle 32 and a pin 31 with a shaft hole 311. This allows the spindle 32 and the pin 31 to move relative to each other axially. Furthermore, a receiving groove 321 is designed on the spindle 32 to release the locking structure 33 from its locked state, allowing the locking structure 33 to retract into the receiving groove 321 and thus unlock. This facilitates the insertion or withdrawal of the locking pin into the second locking structure 23 (locking sleeve) of the driven end motor quick-change structure. A damping force is formed between the pin 31 and the spindle 32, limiting their relative displacement and improving the stability of the locking pin to prevent failure. Simultaneously, the ejector ramp on the spindle 32 makes the locking structure 33 more stable and less prone to failure.
[0068] When using locking pins to lock the quick-change structure of the motor end and the driven end, the output structure 123 of the motor end is aligned with the input structure 21 of the driven end. At the same time, the first positioning structure 13 (positioning protrusion ring), the second positioning structure 22 (positioning hole), the first locking structure 14 (spring locking pin), and the second locking structure 23 (locking sleeve) are aligned. The spindle 32 is controlled to move axially so that the locking structure 33 of the spring locking pin is in the unlocked state. After the two are engaged and in place, the spindle 32 is released. The restoring force of the damping structure 36 causes the spindle 32 to reset, so that the locking structure 33 moves out of the receiving groove 321 and is pushed into the locking port 312, switching to the locked state. The locking structure 33 is locked and partially protrudes from the outer wall of the pin 31. The protruding part of the locking structure 33 is locked on the locking platform structure in the second locking structure 23 of the locking sleeve, thus realizing the docking and locking of the quick-change structure of the motor end and the driven end. When unlocking is required, the control spindle 32 moves axially upwards, causing the locking structure 33 of the spring locking pin to be in the unlocked state, thus disengaging the motor quick-change structure from the driven end, thereby completing the quick removal of the motor 10. Therefore, the spring locking pin structure of this embodiment is simple, easy to operate, highly efficient, highly stable, does not fail, and has strong versatility. It can be used inside a glove box without affecting other work activities inside the glove box.
[0069] In the spring locking pin of this embodiment, optionally, when the damping structure 36 is not deformed, the locking structure 33 is in a locked state; when the operating spindle 32 moves axially and causes the damping structure 36 to deform to a certain extent, the locking structure 33 can be switched to an unlocked state. That is, when the locking pin locks the motor end and the driven end, the damping structure 36 is not deformed, avoiding the instability of the spindle 32 caused by the elastic restoring force of the damping structure 36, ensuring the stability of the locking, and improving the connection effectiveness.
[0070] In this embodiment, when switching the locking structure 33 from the locked state to the unlocked state, the spindle 32 can be pressed inward to move the receiving groove 321 axially inward until it coincides with the locking port 312, thus unlocking the locking structure 33. This type of spring locking pin is defined as a press-type locking pin (see...). Figures 5-7 (As shown). Alternatively, the mandrel 32 can be pulled outwards, causing the receiving groove 321 to move axially outwards until it coincides with the locking port 312, thus unlocking the locking structure 33. This type of spring locking pin is defined as a pull-out locking pin (see...). Figures 8-13 (As shown). The device can be pulled out or pushed in depending on the position of the receiving slot 321. Furthermore, depending on the arrangement of the damping structure 36 between the pin 31 and the spindle 32, the deformation of the damping structure 36 when pulling out or pressing the spindle 32 may be either compression or stretching, and is not limited to this.
[0071] In some embodiments, combined with Figure 9 As shown, the damping structure 36 is connected to the spindle 32 at its end 323, and to the pin 31 at its first shaft end 313. Here, the end 323 of the spindle 32 is the opposite end to the operating end 322 of the spindle 32, which is the end used to operate (pull or press) the spindle 32 along its axial direction. The first shaft end 313 of the pin 31 is the end of the pin 31 on the same side as the operating end 322 of the spindle 32. When the spindle 32 is pulled, the damping structure 36 deforms into compression; when the spindle 32 is pressed, the damping structure 36 deforms into tension.
[0072] In some embodiments, combined with Figure 5 As shown, the damping structure 36 is connected to the spindle 32 at the operating end 322 of the spindle 32, and to the pin 31 at the second end 314 of the pin 31. Here, the second end 314 of the pin 31 refers to one end of the pin 31 on the same side as the end 323 of the spindle 32. When the spindle 32 is pulled, the damping structure 36 deforms in a stretching manner; when the spindle 32 is pressed, the damping structure 36 deforms in a compressive manner.
[0073] Whether the spring locking pin is unlocked by stretching the spindle 32 or by pressing the spindle 32 depends on the relative position of the receiving groove 321 on the spindle 32 and the locking port 312 on the pin 31, as well as the way the damping structure 36 is set between the pin 31 and the spindle 32.
[0074] like Figures 5 to 7As shown, the damping structure 36 is connected to the spindle 32 at the operating end 322 of the spindle 32, and connected to the pin 31 at the second shaft end 314 of the pin 31. When the spring locking pin is in the locked state, the receiving groove 321 is located on the side of the locking port 312 near the first shaft end 313. When the spindle 32 is pressed, the damping structure 36 is compressed, and the receiving groove 321 moves towards the second shaft end 314, approaching the locking port 312. When it coincides with the locking port 312, it is unlocked. In this embodiment, the spring locking pin is defined as a push-button type locking pin (e.g., a button-type locking pin).
[0075] like Figures 8 to 13 As shown, the damping structure 36 is connected to the spindle 32 at the end 323 of the spindle 32, and to the pin 31 at the first shaft end 313 of the pin 31. When the spring locking pin is in the locked state, the receiving groove 321 is located at the second shaft end 314 of the locking port 312. When the spindle 32 is pulled out, the damping structure 36 is compressed, and the receiving groove 321 moves towards the first shaft end 313, approaching the locking port 312. When it coincides with the locking port 312, it is unlocked. In this embodiment, the spring locking pin is defined as a pull-out locking pin.
[0076] In some embodiments, the damping structure 36 includes a spring; one end of the spring is connected to a pin 31, and the other end is connected to a spindle 32. A damping force is formed between the pin 31 and the spindle 32, limiting the relative displacement between them.
[0077] Optionally, such as Figure 5 and Figure 11 As shown, the spring is a compression spring, sleeved on the spindle 32; one end is connected to the pin 31, and the other end is connected to the spindle 32. It has a simple structure, uniform damping force, and good damping effect.
[0078] Optionally, a first retaining ring structure 324 is provided on the peripheral wall of the spindle 32, and one end of the damping structure 36 (spring) is disposed on the first retaining ring structure 324, limiting the displacement of one end of the damping structure 36 (spring). Figure 5 As shown, the first retaining ring structure 324 is attached to the end face of the operating structure 325 of the operating end 322 of the spindle 32, which is connected to the spindle 32. Figure 11 and Figure 12 As shown, the first retaining ring structure 324 is disposed on the outer wall of the end 323 side of the mandrel 32 to form a stop platform.
[0079] Optionally, a second retaining ring structure 315 is provided on the inner wall of the shaft hole 311 of the pin 31, and the other end of the damping structure 36 (spring) is provided on the second retaining ring structure 315. This limits the displacement of the other end of the damping structure 36 (spring). Optionally, as... Figure 5As shown, a shoulder is formed on the inner wall of the shaft hole 311 of the pin 31, and the shoulder serves as the second retaining ring structure 315. Optionally, as... Figure 12 and Figure 13 As shown, the second retaining ring structure 315 can be attached to the end face of the connecting portion 341 of the handle 34 described below. The connecting portion 341 extends into the shaft hole 311 of the pin 31, and the outer wall of the connecting portion 341 is threadedly connected to the inner wall of the shaft hole 311. At this time, the end face of the connecting portion 341 can serve as the second retaining ring structure 315.
[0080] In some embodiments, the spring locking pin further includes a handle 34 disposed on the pin 31. The handle 34 is disposed on the first shaft end 313 of the pin 31 to facilitate operation and realize the relative movement between the pin 31 and the spindle 32, and can be adapted to mechanical control operation, using a robot to complete the connection and locking action.
[0081] In some embodiments, the spring locking pin further includes an operating structure 325, which is disposed at the operating end 322 of the spindle 32. When the locking structure 33 switches from the locked state to the unlocked state, the operating structure 325 moves closer to the handle 34. Adding the operating structure 325 facilitates control of the relative movement between the spindle 32 and the pin 31. By clamping the operating structure 325 and the handle 34 and bringing them closer together, the movement of the spindle 32 can be controlled, completing the unlocking process. The clamping action is simple and easy to implement, suitable for mechanical control, for example, for robotic arms. In particular, when applied to confined spaces such as glove boxes, it facilitates the locking operation of the locking pin by a robotic arm.
[0082] Optionally, the distance between the operating structure 325 and the handle 34 is consistent with the movement displacement of the spindle 32 when the locking structure 33 switches from the locked state to the unlocked state. This allows for precise control of the extension / pressing length of the spindle 32, making operation more convenient. During operation, the operator does not need to judge the displacement of the spindle 32, making it suitable for robotic arm operation. The handle 34 can be integrally formed or separately, without limitation.
[0083] Optionally, the operating structure 325 protrudes from the first shaft end 313 of the pin 31, facilitating operation of the spindle 32.
[0084] Optionally, such as Figure 5 As shown, the operating mechanism 325 is cylindrical. It is a button type, for example, suitable for a push-button locking pin.
[0085] Optionally, such as Figure 8As shown, the operating structure 325 is ring-shaped. This facilitates operation and is suitable for gripping operations by robotic arms. When used in special environments such as glove boxes, the ring-shaped operating structure 325 easily cooperates with the handle 34 to perform pull-out or press-out operations on the spindle 32. For example, it can be used with pull-out locking pins.
[0086] In some embodiments, the operating structure 325 and the operating end 322 of the spindle 32 are connected by a spring pin 326. This ensures a stable connection while also allowing for disassembly.
[0087] In some embodiments, a handle 34 is disposed at the first shaft end 313 of the pin 31. This facilitates the insertion and locking of the locking pin, as well as its removal and release, and also facilitates operation in conjunction with the operating structure 325. The structure of the handle 34 is not limited, as long as it has a structure capable of being gripped / clamped / held. It can be directly disposed on the outer wall of the pin 31.
[0088] Optionally, the handle 34 includes a connecting portion 341 and a gripping portion 343. The connecting portion 341 has a through hole 342, which is coaxial with the shaft hole 311 to connect the connecting portion 341 to the first shaft end 313 of the pin 31. The gripping portion 343 is disposed on the connecting portion 341. The spindle 32 passes through the through hole 342 and is movably disposed within the shaft hole 311 of the pin 31. While ensuring connection strength, it also allows for the detachment of the handle 34 and the pin 31, facilitating disassembly and maintenance, and is suitable for some special environments. By positioning the handle 34 axially on the pin 31, the movement direction of the operating spindle 32 is ensured to be axially on the pin 31, ensuring smooth operation. In this embodiment, the shape of the gripping portion 343 is not limited, and the design is based on ease of clamping.
[0089] Optionally, the holding part 343 is symmetrically arranged on the connecting part 341.
[0090] Optionally, such as Figure 11 and Figure 12 As shown, the gripping part 343 includes an annular gripping part. That is, the handle 34 includes an annular gripping part and a connecting part 341. The connecting part 341 is disposed on the annular gripping part and has a through hole 342. The connecting part 341 is connected to the first shaft end 313 of the pin 31 in a manner coaxial with the shaft hole 311. The through hole 342 connects the shaft hole 311 of the pin 31 with the hollow area 344 of the annular gripping part. The spindle 32 passes through the through hole 342 and is movably disposed in the shaft hole 311 of the pin 31. This facilitates gripping the handle, controlling the operating structure 325 on the spindle 32, and effectively controlling the axial movement of the spindle 32. Moreover, it facilitates unlocking by using clamping.
[0091] In this embodiment, the relative position of the operating structure 325 on the operating end 322 of the spindle 32 and the holding part 343 (annular holding part) is not limited. It can be determined by whether the locking pin pulls the spindle 32 to complete the unlocking or presses the spindle 32 to complete the unlocking.
[0092] Optionally, the operating structure 325 is housed in the hollow region 344 of the annular grip. During clamping, the operating structure 325 moves outward along the axial direction and approaches one side wall of the annular grip, stretching the spindle 32 and unlocking. In this embodiment, by designing the size of the hollow region 344, the distance between the operating structure 325 and the inner wall of the hollow region on the direction of movement (i.e., the aforementioned distance between the operating structure 325 and the handle 34) can be controlled, making it consistent with the movement displacement of the spindle 32 during unlocking, thereby improving unlocking efficiency.
[0093] Optionally, the operating structure 325 is located on the outer side of the annular grip in the axial direction. During clamping, the operating structure 325 moves inward along the axial direction and approaches one side wall of the annular grip, pressing the spindle 32 to unlock. In this embodiment, by setting the distance between the operating structure 325 and the opposite side wall of the annular grip (i.e., the aforementioned distance between the operating structure 325 and the handle 34), it is made consistent with the movement displacement of the spindle during unlocking, thereby improving unlocking efficiency.
[0094] The operating end 322 of the spindle 32 is located in the hollow area 344 of the annular gripping part, which can limit the axial displacement of the spindle 32. By designing the size of the hollow area 344, the axial displacement of the spindle 32 can be limited to match the displacement of the unlocking and locking structure 33, thereby improving unlocking efficiency. Furthermore, during operation, the operator does not need to judge the displacement of the spindle 32, making it suitable for robotic arm operation. The handle 34 can be integrally formed or separately provided; there is no limitation.
[0095] Optionally, the outer wall of the connecting part 341 is threaded to the inner wall of the shaft hole 311 of the pin 31 (e.g., Figure 12 (as shown), or the inner wall of the connecting part 341 is threaded to the outer wall of the pin 31, which is not limited.
[0096] Optionally, the shape of the hollow region 344 of the annular grip portion matches the shape of the operating structure 325.
[0097] Optionally, the hollow area 344 of the annular grip is square, and the operating structure 325 is square-ringed.
[0098] Optionally, the square annular operating structure 325 is adapted to the hollow area 344 of the annular gripping part, and a displacement space for the square annular operating structure 325 is reserved in the axial direction.
[0099] Optionally, an operating structure 325 is provided on the operating end 322 of the spindle 32, and the operating structure 325 is located in the hollow area 344 of the gripping part 343 (annular gripping part).
[0100] Optionally, the hollow area 344 of the gripping part 343 (annular gripping part) is square, and the operating structure 325 is square annular.
[0101] Optionally, the square annular operating structure 325 is adapted to the hollow area 344 of the gripping part 343 (annular gripping part), and a displacement space for the square annular operating structure 325 is reserved in the axial direction.
[0102] Optionally, a stop 345 is provided on the edge of the handle 34, and the stop 345 protrudes from the side where it is located. This facilitates the operation of the robot arm, such as facilitating the gripping and positioning of the robot arm.
[0103] In some embodiments, combined with Figure 10 , Figure 12 and Figure 13 As shown, the spring locking pin also includes a housing 35, which is fitted onto the handle 34 to protect the handle.
[0104] Optionally, the stop 345 is disposed on the housing 35. It can be integrally formed with the housing 35.
[0105] In this embodiment, the number of locking holes 312 on the pin 31 is not limited; it can be one or more, determined according to actual needs. Optionally, as... Figure 5 and Figure 8 As shown, there are multiple locking ports 312. Optionally, the multiple locking ports 312 are evenly distributed on the side wall of the pin 31. Optionally, there are three locking ports 312, evenly distributed on the side wall of the pin 31. The number of locking structures 33 is the same as the number of locking ports 312, and the number of receiving grooves 321 is also the same as the number of locking ports 312.
[0106] In this embodiment, the shape of the receiving groove 321 on the mandrel 32 is not limited, as long as it can accommodate the locking structure 33 so that the locking structure 33 does not extend beyond the outer wall of the pin 31 after it is retracted. At the same time, during the process of the mandrel 32 moving axially to push out the locking structure 33, the shape of the receiving groove 321 does not restrict the movement of the mandrel 32.
[0107] In some embodiments, combined with Figure 5 and Figure 6 , Figure 12 and Figure 13As shown, when the locking structure 33 is in the locked state, the side wall portion of the spindle 32 that abuts against the locking structure 33 is inclined, serving as the ejection inclined surface 3210. The ejection inclined surface 3210 facilitates the ejection of the locking structure 33, does not impede the movement of the spindle 32, and can buffer the radial external force on the locking pin to a certain extent, reducing the probability of damage. In this embodiment, the shape of the second side wall of the receiving groove 321 away from the locking structure 33 is not limited, as long as the locking structure 33 is accommodated in the groove and does not fall out of the receiving groove 321.
[0108] Optionally, the second sidewall 3212 of the receiving groove 321 on the side away from the locking structure 33 is also inclined, and the angle between the second sidewall 3212 and the axial direction is greater than the angle between the ejection inclined surface 3210 and the axial direction.
[0109] Optionally, the ejector ramp 3210 is stepped, and the stepped surface 3211 is inclined. This not only limits the displacement of the locking structure 33 but also facilitates its ejection without hindering the movement of the mandrel 32. It also limits the magnitude of the mandrel 32's displacement to a certain extent, buffering radial external forces. This stepped ramp assists in locking the locking structure 33, buffering even large pressure applied to the second shaft end 314 of the pin 31 and reducing the likelihood of damage to the mandrel 32.
[0110] In some embodiments, combined with Figures 5 to 7 ,as well as Figure 11 and Figure 12 As shown, the receiving groove 321 is a receiving annular groove provided along the peripheral wall of the mandrel 32. It is simple to form and has an effective structure. The receiving annular groove ensures that the end of the mandrel 32 includes a funnel-shaped receiving portion.
[0111] Optionally, one side wall of the receiving annular groove is inclined; when the locking structure 33 is in the locked state, the inclined surface of the receiving annular groove abuts against the locking structure 33, that is, the inclined surface serves as the ejection inclined surface.
[0112] Optionally, the ejector ramp 3210 of the receiving annular groove is stepped, and the stepped surface 3211 is inclined. This stepped ramp can help to lock the locking structure 33, and even if a large pressure is applied to the second shaft end 314 of the pin 31, the pressure will be buffered and the probability of damage to the spindle 32 will be reduced.
[0113] In some embodiments, the angle between the stepped surfaces of the ejector inclined surface 3210 and the axial direction is reduced along the direction from the bottom to the edge of the receiving groove 321 (receiving annular groove). This results in better locking and buffering effects.
[0114] Combination Figure 11As shown, the ejector ramp 3210 includes two steps, and the angle between the stepped surface near the groove edge (i.e., the outer wall of the mandrel) and the axial direction is smaller than the angle between the stepped surface near the bottom of the groove and the axial direction.
[0115] In some embodiments, the locking structure 33 includes a locking portion and a protrusion, the shape of the connection between the protrusion and the locking portion being consistent with the shape of the locking opening 312; and the size of the protrusion is smaller than the size of the locking portion. That is, when the locking structure 33 is in the unlocked state, the protrusion can retract into the receiving groove of the spindle 32, and when the locking structure 33 is pushed out, the locking structure 33 can be locked between the pin 31 and the spindle 32, with the protrusion protruding from the outer side wall of the pin 31 to achieve the locking function.
[0116] Optionally, the end face of the locking part that contacts the spindle 32 is curved, facilitating the movement of the spindle 32.
[0117] Optionally, the locking structure 33 includes a spherical locking structure or an umbrella-shaped locking structure. In the umbrella-shaped locking structure 33, the umbrella portion serves as a locking portion, and the handle portion serves as a protruding portion.
[0118] Below, in conjunction with Figures 5 to 7 The diagram illustrates the process of locking and disassembling the quick-change motor structure at the motor end and driven end using a press-type spring pin. Align the output structure 123 at the motor end with the input structure 21 at the driven end. Simultaneously align the first positioning structure 13 (positioning protrusion ring), the second positioning structure 22 (positioning hole), the first locking structure 14 (spring locking pin), and the second locking structure 23 (locking sleeve). Press the spindle 32 to unlock the locking structure 33. After engaging and positioning both, release the spindle 32. The spindle 32 resets, and the locking structure 33 is pushed out into the locking port 312, switching to the locked state. This achieves the docking and locking of the quick-change motor structure at the motor end and driven end (e.g., ...). Figure 6 (As shown). To unlock, press spindle 32 (as shown). Figure 7 (As shown by the "downward arrow"), the locking structure 33 is in the unlocked state, disengaging the motor end from the driven end of the motor quick-change structure (as shown by the "downward arrow"). Figure 7 (As shown by the "upward arrow"), this completes the quick removal of motor 10.
[0119] Below, in conjunction with Figures 12 to 14 The diagram illustrates the process of locking and disassembling the quick-change motor structure at the motor end and driven end using a pull-out spring pin. The output structure 123 at the motor end is aligned with the input structure 21 at the driven end. Simultaneously, the first positioning structure 13 (positioning protrusion ring), the second positioning structure 22 (positioning hole), the first locking structure 14 (spring locking pin), and the second locking structure 23 (locking sleeve) are aligned. Pulling out the spindle 32 unlocks the locking structure 33 (as shown). Figure 14(As indicated by the middle arrow), after the two are engaged and in place, release the spindle 32. The spindle 32 resets, and the locking structure 33 is pushed out into the locking port 312, switching to the locked state. This allows for the docking and locking of the quick-change structure between the motor end and the driven end. To unlock, pull out the spindle 32 (as shown by the middle arrow). Figure 14 Pulling in the direction indicated by the middle arrow puts the locking structure 33 in the unlocked state, disengaging the motor end from the driven end of the motor quick-change structure, thus completing the quick removal of the motor 10.
