Description

Technical Field

[0001] This application relates to the field of household equipment manufacturing technology, specifically to a docking device and a docking method for controlling the relative position of two workpieces. Background Technology

[0002] Many products require strict control over the relative positions of two components, such as maintaining a fixed gap. If these two components need to maintain a relative gap while docking with the product's mounting body—for example, the first component docks with a fixed part on the mounting body, and the second component docks with a movable part on the mounting body—and after both are installed, maintaining the required gap becomes difficult to guarantee in terms of dimensional accuracy. For instance, the impeller cover of a mixed-flow fan (referring to a fan with a three-dimensional impeller) needs to abut against the outer shell of the fan body, while the impeller needs to be mounted on the fan's shaft. When the impeller cover is installed in a fixed abutment position, it also needs to maintain a gap with the top arc edge of the impeller blades.

[0003] Since the first component, such as the impeller cover, and the second component, such as the impeller, are installed in different positions, and the installation position of one component is movable, such as rotatable, relative to the installation position of the other component, it is difficult to guarantee the installation gap between the two components during production. Summary of the Invention

[0004] In view of this, this application aims to provide a docking device and a docking method for controlling the relative position of two workpieces, which can accurately control the distance between the two workpieces, ensure dimensional accuracy, ensure product performance, and improve the dimensional consistency of products manufactured in the same batch and between different batches, so as to solve the above problems to a certain extent.

[0005] This application provides a docking device, comprising: a first support for fixing a first workpiece; a second support for fixing an installation body, disposed opposite to the first support; and a first pusher disposed opposite to the second support, having a first docking limiting surface that abuts against a second workpiece pre-installed on the installation body; wherein the second support and the first support are movable relative to each other; the first pusher is movable along the docking direction, capable of changing and locking the distance between the first docking limiting surface and the first workpiece, and capable of pushing the second workpiece to move on the installation body.

[0006] In one possible implementation, in the docking direction, the first support is provided with a second docking limiting surface for limiting the first workpiece; the second support is provided with a third docking limiting surface for limiting the mounting body.

[0007] In one possible implementation, the first support is provided with a first circumferential limiting surface for circumferentially limiting the first workpiece; the second support is provided with a second circumferential limiting surface for circumferentially limiting the mounting body.

[0008] In one possible implementation, when the second workpiece is connected to one end of the first connecting portion of the mounting body, the first workpiece is connected to the second connecting portion of the mounting body, and the first connecting portion is movably disposed relative to the second connecting portion, the docking device includes a second pushing member that abuts against the other end of the first connecting portion.

[0009] In one possible implementation, the second pusher is configured to be movable or floating relative to the second support.

[0010] In one possible implementation, the system further includes: a first power member that drives the first support to move along the docking direction; and a second power member that drives the first pusher to move along the docking direction.

[0011] In one possible implementation, the first pusher is movably disposed on the first support, and the first support is provided with a first locking assembly for locking the first pusher.

[0012] In one possible implementation, a plurality of top cylinders with different lengths are provided, and any one of the top cylinders can be detachably connected to the end of the first push member near the second support. The free end face of the top cylinder connected to the first push member forms the first docking limiting surface.

[0013] In one possible implementation, the system further includes: a first pressure sensor for detecting the docking pressure on the first workpiece; a second pressure sensor for detecting the docking pressure on the first pusher; and a controller that is communicatively connected to the two pressure sensors and electrically connected to each power component.

[0014] In one possible implementation, the system further includes: a first support body for fixing the first support; a second support body for fixing the second support; and a guide post for being arranged along the docking direction, wherein the first support body is slidably disposed on the guide post.

[0015] In one possible implementation, a third power source is provided to move the second push member relative to the second support; or, the second push member is floatable relative to the second support, and the second support is provided with a second locking component for locking the second push member.

[0016] This application also provides a docking method for controlling the relative position of two workpieces, applicable to the docking device as described in any of the preceding claims, the docking method comprising the following steps:

[0017] Fix the first workpiece onto the first support;

[0018] The second workpiece is pre-installed onto the first connecting part of the mounting body;

[0019] Secure the mounting body to the second support;

[0020] Both the first workpiece and the first pusher are brought into contact with the second workpiece on the mounting body;

[0021] Increase the distance between the first pusher and the first workpiece along the direction closer to the mounting body, and lock the distance so that the first pusher and the first workpiece are linked.

[0022] The first workpiece and the first pusher are brought close to the mounting body simultaneously, and the second workpiece is pressed to move on the first connecting part until the first workpiece abuts against the second connecting part of the mounting body.

[0023] In one possible implementation, the following steps are also included:

[0024] After the first workpiece and the first pusher have both come into contact with the second workpiece, the first support and the first pusher move in opposite directions synchronously, so that the first workpiece and the first pusher are separated from the second workpiece.

[0025] The distance between the first mating limiting surface and the first workpiece is increased by moving the first pusher relative to the first support, or by replacing the first pusher.

[0026] The docking device provided in this application fixes the product mounting body with a second support, fixes a first workpiece that needs to dock with the mounting body with a first support, and abuts against a second workpiece with a first docking limiting surface of a first pushing member. The second workpiece is a workpiece that has been pre-installed on the mounting body and needs to maintain a target distance from the first workpiece. The first support and / or the second support are movable along the docking direction; the first pushing member is movable, capable of adjusting the distance between the first docking limiting surface and the first workpiece, and locking the distance value after adjustment, so that the first docking limiting surface and the first workpiece are linked, and also capable of pushing the second workpiece, causing the second workpiece to move relative to the mounting body.

[0027] Thus, by adjusting the distance between the first docking limiting surface and the first workpiece, the first docking limiting surface can be made closer to the main body than the first workpiece. When the first docking limiting surface contacts the second workpiece, there is a gap between the first workpiece and the second workpiece. During the synchronous movement of the first workpiece and the first pusher towards the installation body, this gap can always be maintained with the second workpiece. This allows the second workpiece to move to the final installation position after the first workpiece is docked with the installation body, and the first workpiece and the second workpiece have the required target gap.

[0028] This setup, using the docking device provided in this application, allows for precise control of the installation dimensions through adjustments to the device's components during the docking process. It enables accurate control of the distance or relative position between the two workpieces and facilitates adjustment of the distance value as needed. Furthermore, it not only ensures high dimensional accuracy, improving product performance, but also enhances production consistency, increasing the dimensional uniformity between products manufactured in the same batch and between different batches. Moreover, the two workpieces are simultaneously docked and installed onto the mounting body, achieving the required distance at the same time, resulting in a smooth process and improved production efficiency.

[0038] The embodiments of this application aim to provide a docking device. During the docking process, the distance between two workpieces to be docked is precisely controlled by adjusting the components of the docking device, and the two workpieces are simultaneously installed onto the docking mounting body. This ensures that after the workpieces are docked, they have the required target distance, i.e., the relative position of the two workpieces can be controlled. This device can improve the accuracy of the distance or relative position of the two workpieces, the ease of distance adjustment, the dimensional consistency of products manufactured in the same batch and different batches, and production efficiency. It solves the problem in the prior art that it is difficult to guarantee a fixed distance between two workpieces that are docked onto relatively movable parts of the mounting body during product manufacturing.

[0039] The embodiments of this application also aim to provide a docking method for controlling the relative position of two workpieces. This method belongs to the same inventive concept as the docking device described above, and achieves the technical effect of synchronously installing two workpieces to different connection parts on the mounting body, and precisely controlling the distance between the two workpieces during the docking process, thereby improving product performance and production efficiency.

[0040] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Please refer to the attached document. Figure 1-7This application provides a docking device for docking a first workpiece 13, a second workpiece 14, and a mounting body 15, and for achieving a target distance between the first workpiece 13 and the second workpiece 14. The mounting body 15 can be the main body of a product or other types of mounting bodies, such as a mounting support, a mounting frame, or a mounting structure composed of several components. The docking device includes a first support 1, a second support 2, and a first pusher 3. The first support 1 and the second support 2 are positioned opposite each other and spaced apart, and the first pusher 3 is also positioned opposite and spaced apart from the second support 2, meaning the first support 1 and the first pusher 3 are located on the same side. The first support 1 is used to fix the first workpiece 13, and the second support 2 is used to fix the mounting body 15. The first workpiece 13 needs to dock with the second connecting portion 152 on the mounting body 15. The second workpiece 14 is pre-installed onto the mounting body 15; pre-installation means that the second workpiece 14 is connected to the first connecting portion 151 on the mounting body 15, but is not fully installed. The first pushing member 3 has a first docking limiting surface 301, which abuts against the second workpiece 14 pre-installed on the mounting body 15. The first support 1 and / or the second support 2 are movable along the docking direction to allow the first workpiece 13 and the mounting body 15 to move closer or further apart. The movable first pushing member 3 can, on the one hand, move away from or closer to the mounting body 15 to contact the second workpiece 14, and also push against the second workpiece 14, allowing it to move within the mounting body 15. On the other hand, it can also move or adjust the position of the first docking limiting surface 301 along the docking direction, thereby adjusting the relative position of the first docking limiting surface 301 and the first workpiece 13. For example, it can increase the distance between the first docking limiting surface 301 and the first workpiece 13, and after adjusting the distance, lock this distance value so that the first docking limiting surface 301 and the first workpiece 13 maintain this distance value and move synchronously (without relative displacement during movement).

[0042] The following explanation is based on actual usage. In actual use, firstly, move the first support 1 or the second support 2 so that the first workpiece 13 comes into contact with the second workpiece 14 pre-installed on the mounting body 15. After contact, maintain the contact state, and then, or simultaneously, move the first pressing member so that the first mating limiting surface 301 also comes into contact with the second workpiece 14 on the mounting body 15. This step is equivalent to zeroing, which can accurately determine the initial relative position of the first mating limiting surface 301 and the first workpiece 13. Then, the first pushing member 3 pushes the second workpiece 14 while the first workpiece 13 remains stationary, or the first workpiece 13 and the first pushing member 3 are kept at zero. The first workpiece 13 moves away from the second workpiece 14 in a synchronous manner, and then gradually moves closer to the second workpiece 14 in the docking direction. This increases the distance between the first docking limiting surface 301 and the first workpiece 13, causing the first docking limiting surface 301 to move closer to the mounting body 15, making it closer to the mounting body 15 relative to the first workpiece 13. The increased distance is the same as the target distance required between the first workpiece 13 and the second workpiece 14. This distance is then locked, i.e., the relative positions of the first workpiece 13 and the first docking limiting surface 301 are locked, maintaining this distance and linking the first docking limiting surface 301, the first pusher 3, and the first support 1. Thus, when the first docking limiting surface 301 contacts the second workpiece 14, there is a distance between the first workpiece 13 and the second workpiece 14, and this distance is maintained throughout the synchronous movement of the first workpiece 13 and the first pusher 3 towards the mounting body 15.

[0043] Subsequently, the first support 1 and the first pusher 3 move synchronously (taking the movement of the first support 1 and the first pusher 3 relative to the second support 2 as an example, or the movement of the second support 2 relative to the first support 1 and the first pusher 3), and the first mating limiting surface 301 and the first workpiece 13 move synchronously and continue to approach the mounting body 15. During this process, the first mating limiting surface 301 pushes against the second workpiece 14, causing the second workpiece 14 to move relative to the mounting body 15. Thus, the first workpiece 13 will always maintain a distance from the second workpiece 14 (this distance is the distance value that the first mating limiting surface increases relative to the first workpiece in the direction of approaching the mounting body), until the first workpiece 13 moves to the mating surface 1521 on the mounting body 15 (the mating surface is as follows). Figure 3 As shown, the first workpiece 13 is installed in place, the first support 1 and the first pusher 3 stop moving, and the second workpiece 14 also moves from the pre-installed position to the final installation position and achieves docking. The first workpiece 13 and the second workpiece 14 have a target distance and a high-precision relative distance.

[0044] In short, the docking device provided in this application first zeroes the distance between the first docking limiting surface 301 and the first workpiece 13, and then increases the distance value to be the same as the target distance between the first workpiece 13 and the second workpiece 14. Then, the distance value is locked and the first pusher 3 and the first workpiece 13 are linked together. During the process of approaching the mounting body 15, the distance value is kept moving synchronously, and the first pusher 3 pushes the second workpiece 14 to move relative to the mounting body 15. Thus, after the first workpiece 13 is docked with the mounting body 15, it has the required target distance with the second workpiece 14, thereby achieving the purpose of synchronous installation of the two workpieces and controlling the relative installation position of the two workpieces.

[0045] It can be seen that after zeroing, increasing and locking the distance between the first docking limiting surface 301 and the first workpiece 13 can accurately control the spacing size after the first workpiece 13 and the second workpiece 14 are installed in place; adjusting the increased distance value can match different ranges of spacing size; the two workpieces are pressed in simultaneously, and the relative installation position of the two workpieces is controlled, with high precision and high efficiency.

[0046] This configuration, using the docking device provided in this application, allows for docking and control of the installation dimensions of the docking workpieces through adjustments to the device's components during the docking process. This enables precise control of the distance between the two workpieces and facilitates adjustment of the distance value as needed. Furthermore, it not only ensures high dimensional accuracy, improving product performance, but also enhances production consistency, increasing the dimensional uniformity of products manufactured in the same batch and between different batches. Moreover, during the docking process, the first workpiece 13 and the second workpiece 14 are simultaneously assembled onto the mounting body 15, meeting the docking position requirements of both workpieces concurrently. This eliminates the need for post-installation adjustments, resulting in a smooth and efficient installation process that improves production efficiency, especially for mass-produced products, significantly increasing the overall efficiency of batch assembly.

[0047] The docking device provided in this application embodiment is suitable for controlling the relative position of two components that need to be installed on the same mounting body 15, and is also suitable for controlling the distance between two docking components.

[0048] For example, when assembling a fan, the mounting body 15 can specifically be the fan body including components such as the casing, rotor, and stator. The first workpiece 13 is an impeller cover, and the second workpiece 14 is an impeller. The attached diagram shows the case where the first workpiece 13 is the impeller cover and the second workpiece 14 is the impeller. The impeller cover needs to be mated with the casing of the mounting body 15, and the impeller is mounted on the shaft of the mounting body 15. The first support 1 is used to fix the impeller cover, and the second support 2 is used to fix the fan body pre-installed with the impeller. The first mating limiting surface 301 of the first pushing member 3 is used to abut against the top end of the impeller. The first support 1 has a through hole opposite to the cover opening of the impeller cover. The first pushing member 3 passes through the through hole on the first support 1 and the cover opening of the impeller cover, and can abut against the end face of the impeller.

[0049] In the first state, the impeller cover is in contact with the impeller blades on the main body of the fan, and the first docking limiting surface 301 is in contact with the top of the impeller, realizing zero operation;

[0050] In the second state, the first pusher 3 pushes the impeller to move closer to the fan body, thereby increasing the distance between the first mating limiting surface 301 and the impeller cover. Alternatively, the impeller cover and the first pusher 3 maintain a zero relative position and move synchronously in the opposite direction away from the fan body. Then, the distance between the first mating limiting surface 301 and the impeller cover in the direction of gradually approaching the fan body is increased, so that the first mating limiting surface 301 moves a certain distance relative to the impeller cover in the direction of approaching the fan body. This increased distance is the same as the required spacing between the impeller and the impeller cover.

[0051] In the third state, the relative position of the first docking limiting surface 301 and the impeller cover is locked. The first pushing member 3 and the first support 1 are linked and move towards the fan body simultaneously. When the first docking limiting surface 301 contacts the impeller, there is a gap between the impeller cover and the impeller. During the movement, the first pushing member 3 pushes the impeller to move on the rotating shaft of the fan body. In this way, the impeller cover abuts against the casing of the fan body, the impeller moves to the final installation position, and the impeller cover and the impeller have the target gap.

[0052] By assembling the impeller cover of the fan using the docking device provided in this application, the blade tip clearance of the 3D impeller electric fan for vacuum cleaners can be precisely adjusted. It is applicable to electric fans with two different main body structures: cantilever structure and two-end support structure. It is easy to use and has good feasibility, ensuring precise control of key dimensions without excessive cost.

[0053] The following description continues with other embodiments of the docking device provided in this application. In some embodiments, such as... Figure 2As shown, the first support 1 is provided with a second docking limiting surface 101 that limits the docking direction of the first workpiece 13; and the second support 2 is provided with a third docking limiting surface 201 that limits the docking direction of the mounting body 15. When the first workpiece 13 is fixed to the first support 1, a local area, or end face or step surface, on it will abut against the second docking limiting surface 101, thereby limiting and fixing the docking direction. Similarly, when the mounting body 15 is installed on the second support 2, a local area abuts against the third docking limiting surface 201, thereby limiting and fixing the docking direction. In this way, on the one hand, the first workpiece 13 and the mounting body 15 can be stably docked and limited, preventing unnecessary movement in the docking direction and affecting the dimensional accuracy after docking; on the other hand, when adjusting the distance between the first docking limiting surface 301 and the first workpiece 13, the relative distance between the first docking limiting surface 301 and the second docking limiting surface 101 can be adjusted with the second docking limiting surface 101 as a reference surface, which is more conducive to precise control of dimensions.

[0054] like Figures 3 to 5 As shown, when the fan body and the impeller cover are docked, the first support 1 has an axial limiting surface that abuts against the outer end face of the impeller cover, namely the second docking limiting surface 101, and the second support 2 has an axial limiting surface that abuts against the end face of the casing, namely the third docking limiting surface 201.

[0055] In some embodiments, the first support 1 is provided with a first circumferential limiting surface 102 for circumferentially limiting the first workpiece 13, and the first circumferential limiting surface 102 abuts against the outer circumferential surface of the first workpiece 13; and the second support 2 is provided with a second circumferential limiting surface 202 for circumferentially limiting the mounting body 15, and the second circumferential limiting surface 202 abuts against the outer circumferential surface of the mounting body 15. This further enhances the stability of the first workpiece 13 and the mounting body 15, preventing shaking or misalignment.

[0056] The docking device provided in this application is applicable to the assembly of two components respectively installed on relatively fixed parts of the mounting body 15, and is also applicable to the assembly of two components respectively installed on different relatively movable parts of the mounting body 15.

[0057] In some embodiments, when the second workpiece 14 is connected to one end of the first connecting portion 151 of the mounting body 15, and the first workpiece 13 is used to mate with the second connecting portion 152 of the mounting body 15, and the first connecting portion 151 is movably (movement includes rotation and sliding, etc.) relative to the second connecting portion 152, the docking device further includes a second pusher 12 that abuts against the other end of the first connecting portion 151 to limit the docking direction. Thus, when the mounting body 15, pre-installed with the second workpiece 14, is installed onto the second support 2, the fixed part of the mounting body 15, i.e., the first connecting part 151 that docks with the first workpiece 13, is limited and supported by the third docking limiting surface 201. The movable part of the mounting body 15, i.e., the second connecting part 152 that installs the second workpiece 14, is limited and supported by the second pushing member 12. The two relatively movable mounting parts are respectively limited and supported, which enhances the fixation of the relative position of the two parts. In this way, the double limiting support and the synchronous pressing of the two workpieces ensure the stability of the docking installation of the two workpieces. It can also prevent the movement dimension of the second workpiece 14 during the docking process from being inconsistent with the expected dimension, thus affecting the dimensional accuracy of the final relative position of the two workpieces.

[0058] like Figure 3 As shown, when assembling the fan body and impeller cover, a second pusher 12 is also provided on the second support 2, which is used to abut against the end face of the shaft away from the impeller.

[0059] In some embodiments, the second pusher 12 is movable or floating relative to the second support 2. Thus, the second pusher 12 is adjustable relative to the second support 2, and can provide close support for the second connecting part 152 (e.g., the housing) and the first connecting part 151 (e.g., the shaft) fixed to the mounting body 15, thus avoiding suspension.

[0060] The first pushing member 3 can be rod-shaped, with the end face of the rod forming the first mating limiting surface 301. Alternatively, the first pushing member 3 can include a rod and a pushing head, such as a pushing cylinder 31, connected to the rod, with the first mating limiting surface 301 formed by the end face of the pushing head, such as the pushing cylinder 31. The second pushing member 12 can be rod-shaped, with its end face abutting against the first connecting portion 151 of the mounting body 15 to limit and support the first connecting portion 151.

[0061] In the above embodiments, the movement of the first support 1 and the first pushing member 3 can be achieved manually or by being driven by a power device. Similarly, when the second pushing member 12 is moved, it can also be achieved by being driven by a power device.

[0062] When the first pusher 3 is moved by the power device, the distance between the first docking limiting surface 301 and the second docking limiting surface 101 can be adjusted directly by moving the first pusher 3.

[0063] For example, in some embodiments, the docking device is further provided with a first power member and a second power member. The first power member drives the first support 1 or the second support 2 to move along the docking direction to get closer to or away from the other support. The second power member drives the first pusher 3 to move along the docking direction to adjust the distance between the first docking limiting surface 301 and the second docking limiting surface 101, and can push the second workpiece 14 to move in conjunction with the first workpiece 13.

[0064] like Figure 5 As shown, taking the movement of the first support 1 as an example, the first support 1 and the first pusher 3 are driven by two independent power components, and can move relative to each other to contact the second workpiece 14 for zeroing operation. They can also adjust the distance between the first docking limiting surface 301 and the second docking limiting surface 101, or move synchronously to lock the adjusted relative position of the first docking limiting surface 301 and the second docking limiting surface 101, that is, the relative position of the first support 1 and the first pusher 3. Then, while pushing the second workpiece 14 to move, they simultaneously approach the mounting body 15 until the first workpiece 13 docks with the mounting body 15.

[0065] In some embodiments, the docking device is further provided with a third power component to drive the second pusher 12 to move along the docking direction.

[0066] When the first support 1, the first pusher 3, and the second pusher 12 are moved by the power component, it is necessary to accurately determine the stopping point. For example, during zeroing operations, it is necessary to stop the movement of the first support 1 and the first pusher 3 in a timely manner. Therefore, in a further embodiment, the docking device is also equipped with a controller, a first pressure sensor, and a second pressure sensor. The first pressure sensor is installed on the first support 1 or the first power component to detect the docking pressure on the first workpiece 13; the second pressure sensor is installed on the first pusher 3 or the second power component to detect the docking pressure on the first pusher 3; the controller is communicatively connected to the two pressure sensors and electrically connected to each power component. When the first support 1 moves the first workpiece 13 to the point where the first workpiece 13 contacts the second workpiece 14, the first pressure sensor feeds back different pressure signals, and the controller stops the first power component in a timely manner to prevent the first workpiece 13 from continuing to move downward and pushing the second workpiece 14. When the first pusher 3 moves to the first docking limit surface 301 and comes into contact with the second workpiece 14, the second pressure sensor feeds back different pressure signals, and the controller stops the second power component in time to prevent it from continuing to move downward and push the second workpiece 14.

[0067] Similarly, in some embodiments, the docking device is also provided with a third pressure sensor, which is installed on the second push member 12 or the third power member, to detect the pressure on the second push member 12. In this way, when the second push member 12 contacts the first connecting part 151 of the mounting body 15 and provides limiting support for the first connecting part 151, such as the rotating shaft on the fan body, the third pressure sensor feeds back a signal, and the third power member stops driving the second push member 12 in time.

[0068] The aforementioned power components can be cylinders or motors. The motor converts rotational power into kinetic power through a lead screw module-like transmission structure.

[0069] When the first support 1 and the first pusher 3 are moved manually, the first pusher 3 can be movably mounted on the first support 1, and the first support 1 is also provided with a first locking component 8 for locking the first pusher 3. Thus, after zeroing, the first pusher 3 can be locked to maintain the relative position of the first mating limiting surface 301 and the second mating limiting surface 101 at the time of zeroing. Then, moving the first support 1 will simultaneously move the first support 1 and the first pusher 3 away from the second workpiece 14. Then, the first pusher 3 can be unlocked to adjust the distance between the first mating limiting surface 301 and the second mating limiting surface 101. After adjustment, the first positioning component is relocked, and the first mating limiting surface 301 and the second mating limiting surface 101 maintain a fixed distance, with the first support 1 and the first pusher 3 linked together.

[0070] Specifically, the arrangement of the first pusher 3 on the first support 1 can be as follows: Figure 1 and Figure 2 As shown, the first support 1 is provided with a through hole for the end of the first pusher 3 near the second support 2 to pass through, and for the first pusher 3 to move relative to the first support 1. The other end of the first pusher 3 is provided with an anti-detachment boss or other anti-detachment structure to prevent the first pusher 3 from detaching from the through hole.

[0071] The first locking component 8 is mounted on the first support 1 and can be a clamp-like structure (such as...). Figure 1 and 2 As shown), it has a ring body for clamping the first pushing member 3 and an adjusting member, such as a bolt, for adjusting the tightness of the ring body. The first locking assembly 8 can also be an expansion screw type structure, such as... Figure 7As shown, an expansion tube is sleeved outside the first pusher 3. The expansion tube is fixedly connected to the first support 1. The tail of the first pusher 3 is conical, and the inner diameter of the cone is larger than the inner diameter of the expansion tube. When the first pusher 3 is turned, it moves outward from the expansion tube and closer to the mounting body 15. The axial movement of the thread causes the conical part to move, thereby forming a large positive pressure on the outer circumferential surface of the expansion tube. In addition, the angle of the cone is very small, thus forming a frictional self-locking between the expansion tube and the cone, thereby achieving the function of locking the first pusher.

[0072] To enhance the driving force of docking, a pressure cylinder 11 can be provided. The pressure cylinder 11 is movably positioned above the first support 1. After the adjustment is completed, the pressure cylinder 11 presses down on the first support 1, causing the first support 1 and the first pusher 3 to move synchronously. The pressure cylinder 11 can be a counterweight or can be moved by a power component.

[0073] In manual movement, the distance between the first docking limiting surface 301 and the second docking limiting surface 101 can be adjusted by manually moving the first pushing member 3 relative to the first support 1. Alternatively, in some embodiments, to ensure the accuracy of the adjusted distance, the docking device is further provided with multiple top cylinders 31 with different lengths. Any one of the top cylinders 31 can be detachably connected to the end of the first pushing member 3 near the second support 2, and the free end (the end near the second support 2) of the top cylinder 31 connected to the first pushing member 3 forms the aforementioned first docking limiting surface 301. With this configuration, after zeroing, the first pushing member 3 can be directly locked, and then a longer top cylinder 31 can be installed or replaced to adjust the distance between the first docking limiting surface 301 and the second docking limiting surface 101. In embodiments where the first support 1 and the first pushing member 3 are moved by a power member, the aforementioned top cylinder 31 can also be provided.

[0074] In the manual embodiment, the second pusher 12 is buoyantly mounted on the second support 2. For example, one end of the second pusher 12 is used to abut against the mounting body 15, and the other end is elastically connected to the second support 2 via an elastic element, such as elasticity. In this way, the second pusher 12 can conform to the actual position of the first connecting portion 151 of the mounting body 15 for limiting support. At the same time, the second support 2 is provided with a second locking assembly 9 for locking the second pusher 12. Thus, after the second pusher 12 abuts against the first connecting portion 151 of the mounting body 15, locking the second pusher 12 can prevent the active first connecting portion 151 of the mounting body 15 from moving during the docking process, for example, when the first pusher 3 pushes the second workpiece 14 to move relative to the mounting body 15, thus affecting the final docking dimensional accuracy.

[0075] The second locking component 9 is mounted on the second support 2 and can be a clamp-like structure (such as...). Figure 1 and 2As shown), it has a ring for clamping the second pusher 12 and an adjusting element, such as a bolt, for adjusting the tightness of the ring. The first locking assembly 8 can also be an expansion screw type structure, such as... Figure 7 As shown.

[0076] When manually moving the first support 1, to ensure the coaxiality of the first support 1 and the second support 2, as follows: Figure 1 As shown, the docking device also includes a first support body 4, a second support body 5, and a guide post 6. The first support body 4 fixes the second support 2; the second support body 5 fixes the first support 1; the first support body 4 and the second support body 5 are arranged opposite to each other and spaced apart; the guide post 6 is arranged along the direction from the first support body 4 to the second support body 5; the first support body 4 is slidably mounted on the guide post 6 and moves along the guide post 6 to approach or move away from the second support 2. This arrangement can ensure high coaxiality between the first support 1 and the second support 2, maintaining high coaxiality during workpiece fixing, zeroing operations, and docking operations.

[0077] like Figure 1 As shown, a stop plate 7 is also provided above the first support body 4 to prevent the first support body 4 from falling off the guide post 6. A third locking assembly 10 is provided on the guide post 6 to lock the first support body 4, so that the first support body 4 can be fixed on the guide post 6 when needed. The third locking assembly 10 is provided on the guide post 6 and can be a clamp-like structure.

[0078] The first support 4 and the second support 5 can be arranged vertically. In this way, the first support 4 can move downwards under gravity, bringing the first support 1 closer to the second support 2. Alternatively, an elastic element can be provided between the first support 4 and the stop plate 7. When the first support 1 on the first support 4 is close to the second support 2, for example, when the first workpiece 13 is in contact with the mounting body 15, the elastic element is in its original state. When the first support 4 moves away from the second support 2, the elastic element is compressed and undergoes elastic deformation. Thus, under the action of the elastic element, the first support 4 can bring the first support 1 closer to the mounting body 15 on the second support 2 for docking, increasing the docking pressure.

[0079] like Figure 1 and Figure 6 As shown, the first support 1 may have a partial cavity to accommodate the first workpiece 13. The second mating limiting surface 101 is formed by a stepped surface on the side wall of the cavity, and the first circumferential limiting surface 102 is formed by the side wall of the cavity. The first circumferential limiting surface 102 may be a complete annular surface, as shown in the figure, or it may be formed by two, three, or more side wall surfaces arranged circumferentially. When the outer circumferential surface of the first workpiece 13 is an arc-shaped surface, the first circumferential limiting surface 102 is also a matching arc-shaped limiting surface.

[0080] Similarly, the second support 2 may also have a partial cavity to accommodate the mounting body 15, with the third mating limiting surface 201 formed by a stepped surface on the side wall of the cavity, and the second circumferential limiting surface 202 formed by the side wall of the cavity. The second circumferential limiting surface 202 may be a complete annular surface, or it may be formed by two, three, or more side wall surfaces arranged circumferentially. When the outer circumferential surface of the mounting body 15 is an arc-shaped surface, the first circumferential limiting surface 102 is also a matching arc-shaped limiting surface.

[0081] This application also provides a docking method for controlling the relative position of two workpieces, applicable to the docking device described in any of the above embodiments, the method comprising the following steps:

[0082] Fix the first workpiece 13 to the first support 1;

[0083] The second workpiece 14 is pre-installed onto the first connecting part 151 of the mounting body 15;

[0084] Fix the main body 15 to the second support 2;

[0085] Move the first support 1 and the first pusher 3 so that the first workpiece 13 and the first pusher 3 both come into contact with the second workpiece 14 on the mounting body 15;

[0086] Along the moving direction of the first support 1, increase the distance between the first pusher 3 and the first workpiece 13, and lock the distance so that the first pusher 3 and the first workpiece 13 are linked together.

[0087] The first workpiece 13 and the first pusher 3 are brought close to the mounting body 15 simultaneously, and the second workpiece 14 is pressed to move on the first connecting part 151 until the first workpiece 13 abuts against the second connecting part 152 of the mounting body 15.

[0088] With this setup, the above method, using a docking device, can achieve the technical objective of simultaneously installing two workpieces onto different parts of the mounting body 15, and accurately controlling the relative positions of the two workpieces.

[0089] In some embodiments, the following steps are also included:

[0090] After the first workpiece 13 and the first pusher 3 come into contact with the second workpiece 14, the first support 1 and the first pusher 3 move in opposite directions and synchronously, so that the first workpiece 13 and the first pusher 3 are separated from the second workpiece 14.

[0091] By moving the first pusher 3 relative to the first support 1, or by replacing the first pusher 3, the distance between the first docking limiting surface 301 and the first workpiece 13 can be changed, for example, by increasing the distance between the first docking limiting surface 301 and the docking limiting surface on the first workpiece 13, so as to adjust the distance between the first workpiece 13 and the second workpiece 14.

[0092] Alternatively, in some embodiments, after the first workpiece 13 and the first pusher 3 have both come into contact with the second workpiece 14, the first pusher 3 pushes the second workpiece 14 to move a preset distance value toward the mounting body 15. This distance value is the same as the target distance required between the first workpiece 13 and the second workpiece 14.
