Description

Technical Field

[0001] This application relates to the field of machining positioning technology, and in particular to a positioning and clamping mechanism. Background Technology

[0002] In the field of machining and manufacturing, the precise positioning and reliable fixing of perforated parts (such as round holes or U-shaped elongated hole components) are key processes to ensure the quality of subsequent processing or assembly. During processing, the perforated parts need to be aligned with the center first to ensure accurate positioning, and then fixed to facilitate subsequent processing.

[0003] However, currently, the center alignment and clamping of perforated parts can only be completed separately. That is, the center alignment or internal hole clamping of perforated parts can only be performed separately. It is not possible to fix them by clamping them through the internal hole after center alignment. Alternatively, external auxiliary devices can be used, which has the problems of large space occupation and high cost. Utility Model Content

[0004] Therefore, it is necessary to provide an alignment and clamping mechanism to address the current problem that it is impossible to simultaneously achieve center alignment and inner hole clamping and fixation of perforated parts. This mechanism can achieve center alignment and clamping and fixation of perforated parts without the need for separate alignment and clamping, thus improving efficiency. At the same time, it eliminates the need for external auxiliary devices, thereby saving costs and space.

[0005] A positioning and clamping mechanism is used for positioning and clamping parts with holes, the positioning and clamping mechanism comprising:

[0006] Alignment assembly, including alignment drive and alignment component, wherein the alignment component is disposed on the alignment drive and the alignment drive is capable of driving the alignment component to move, such that the alignment component extends into or exits from the alignment hole of the perforated part; and

[0007] A clamping assembly includes a clamping drive and a locking member. The clamping drive is disposed on the alignment member, and the locking member is movably disposed on the alignment member. The clamping drive can drive the locking member to rotate so that the locking member extends out of the outer wall of the alignment member and abuts against the inner wall of the alignment hole.

[0008] In one embodiment of this application, the alignment component includes an alignment shaft and a guide shaft. One end of the alignment shaft is connected to the alignment drive, and the guide shaft is disposed at the other end of the alignment shaft and guides the alignment shaft to move into the alignment hole.

[0009] And / or, the longitudinal cross-sectional shape of the alignment component is adapted to the longitudinal cross-sectional shape of the alignment hole, and there is a micro gap between the outer wall of the alignment component and the inner wall of the alignment hole;

[0010] And / or, one end of the alignment component is detachably connected to the alignment drive.

[0011] In one embodiment of this application, the alignment drive includes an alignment cylinder, an alignment piston, and an alignment piston rod. The alignment piston is disposed in the alignment cylinder, and one end of the alignment piston rod is connected to the alignment piston, while the other end extends through the alignment cylinder and is connected to the alignment component.

[0012] In one embodiment of this application, the alignment piston divides the alignment cylinder into a first cavity and a second cavity. The alignment drive further includes a first connector communicating with the first cavity and a second connector communicating with the second cavity. The first connector or the second connector is supplied with driving fluid, which can drive the alignment piston to move the alignment component into or out of the alignment hole through the alignment piston rod.

[0013] In one embodiment of this application, the alignment member has a mounting cavity and a locking hole extending radially into the mounting cavity, the clamping drive and the locking member are located in the mounting cavity, and the locking member is capable of extending or retracting from the locking hole to abut or disengage from the inner wall of the alignment hole.

[0014] In one embodiment of this application, the locking member includes a driving body and a locking body. The driving body is rotatably disposed in the mounting cavity, and the locking body is disposed at one end of the driving body and protrudes from the driving body. The pressing driving member can push the driving body to make the locking body extend out of the locking hole and abut against the inner wall of the alignment hole.

[0015] In one embodiment of this application, the driving body has a driving ramp, and the locking body protrudes from the driving body and has a locking arc surface;

[0016] Alternatively, the driving body and the locking body may be locking cams.

[0017] In one embodiment of this application, the alignment component further has a reset hole extending into the mounting cavity, and the clamping assembly further includes a reset member disposed in the reset hole and extending into the mounting cavity. The reset member can abut against the locking member to retract the locking member into the locking hole.

[0018] In one embodiment of this application, the clamping drive includes a clamping cylinder, a clamping piston, and a clamping piston rod. The clamping cylinder is disposed in the mounting cavity, the clamping piston is disposed in the clamping cylinder, one end of the clamping piston rod is connected to the clamping piston, and the other end can extend through the clamping cylinder and abut against or disengage from the locking member.

[0019] In one embodiment of this application, the clamping drive further includes a third connector located outside the alignment drive and passing through the alignment drive to the clamping cylinder. The third connector can allow or discharge driving fluid to drive the clamping piston to abut or disengage the clamping piston rod from the locking member.

[0020] By adopting the above technical solution, this application has at least the following technical effects:

[0021] When the alignment and clamping mechanism of this application aligns and clamps a perforated part, the alignment drive drives the alignment component to extend, so that the alignment component extends into the alignment hole of the perforated part, and the perforated part is centered and aligned through the alignment component. Subsequently, the clamping drive drives the locking component to extend out of the alignment component and abut against the inner wall of the alignment hole. The clamping and fixing of the perforated part is achieved by the alignment component and the locking component abutting against the inner wall of the alignment hole. This alignment and clamping mechanism sets the clamping drive and the locking component on the alignment component. After the alignment drive and the alignment component are centered and aligned with the perforated part, the clamping drive and the locking component clamp and fix the perforated part. In this way, the alignment and clamping mechanism can achieve center alignment and clamping fixation of the perforated part, which is convenient for subsequent production and processing of the perforated part. It eliminates the need for separate alignment and clamping, improving efficiency. At the same time, the alignment and clamping mechanism has a simple structure and does not require external auxiliary devices, thus saving costs and space. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] In the field of machining and manufacturing, the precise positioning and reliable fixing of perforated parts (such as round holes or U-shaped elongated hole components) are key processes to ensure the quality of subsequent processing or assembly. During processing, the perforated parts need to be centered and aligned first to ensure accurate positioning, and then fixed to facilitate later processing. However, currently, the center alignment and clamping of perforated parts can only be completed separately. That is, the perforated parts can only be centered and aligned or clamped internally separately. It is not possible to fix them by clamping internally after center alignment, or to use external auxiliary devices, which has the problems of large space occupation and high cost.

[0036] For this purpose, please refer to Figures 1 to 3 This application provides a positioning and clamping mechanism 10, which is used to position and clamp a perforated part 30 so that the perforated part 30 can be processed later, including but not limited to machining. Figure 1This is a schematic diagram of a perforated part 30 according to an embodiment of this application. Figure 2 Ten pairs of alignment and clamping mechanisms according to an embodiment of this application Figure 1 The diagram shown illustrates the alignment and clamping of the perforated part 30. Figure 3 for Figure 2 The perspective view shown shows the alignment and clamping mechanism 10 clamping the perforated parts 30.

[0037] like Figure 1 As shown, the perforated part 30 has a positioning hole 301. The positioning and clamping mechanism 10 can extend into the positioning hole 301 to center-align the perforated part 30, making the central axis of the positioning hole 301 coincide with the central axis of the positioning and clamping mechanism 10. Subsequently, the positioning and clamping mechanism 10 can abut against the inner wall of the positioning hole 301 to clamp and fix the perforated part 30. In this way, the positioning and clamping mechanism 10 completes the positioning and clamping of the perforated part 30, realizing the mechanical positioning of the perforated part 30. Then, the perforated part 30 can be machined using machining equipment.

[0038] It is worth noting that the type and size of the perforated part 30 are not limited in principle, as long as the perforated part 30 has alignment holes 301. In this embodiment, the perforated part 30 is a liquid crystal glass substrate. Of course, in other embodiments of this application, the perforated part 30 can also be other structural forms that require alignment and clamping. For example... Figure 1 As shown, in this embodiment, the alignment hole 301 is a circular hole. Of course, in other embodiments of this application, the alignment hole 301 may also be a hole of other shapes.

[0039] The alignment and clamping mechanism 10 of this application can achieve center alignment and clamping fixation of the perforated part 30, which facilitates the subsequent production and processing of the perforated part 30. It eliminates the need for separate alignment and clamping, thereby improving efficiency. At the same time, the alignment and clamping mechanism 10 has a simple structure and does not require external auxiliary devices, thus saving costs and space. The following describes the specific structure of the alignment and clamping mechanism 10 in some embodiments.

[0040] See Figures 2 to 4In one embodiment, the alignment and clamping mechanism 10 includes an alignment assembly 100 and a clamping assembly 200. The alignment assembly 100 includes an alignment drive 110 and an alignment member 120. The alignment member 120 is disposed on the alignment drive 110, and the alignment drive 110 can drive the alignment member 120 to move, so that the alignment member 120 extends into or exits the alignment hole 301 of the perforated part 30. The clamping assembly 200 includes a clamping drive 210 and a locking member 220. The clamping drive 210 is disposed on the alignment member 120, and the locking member 220 is movably disposed on the alignment member 120. The clamping drive 210 can drive the locking member 220 to rotate, so that the locking member 220 extends out of the outer wall of the alignment member 120 and abuts against the inner wall of the alignment hole 301. Figure 4 for Figure 3 The enlarged view of the alignment and clamping mechanism 10 shown is used to align and clamp the perforated parts 30 at point A.

[0041] The alignment assembly 100 is a structure for aligning the alignment and clamping mechanism 10 with the perforated part 30, and the clamping assembly 200 is a structure for clamping the alignment and clamping mechanism 10 with the perforated part 30. When the alignment and clamping mechanism 10 is in use, the alignment assembly 100 is installed on a support component of the processing equipment, such as a support plate, support base, or support frame, and the clamping assembly 200 is movably disposed on the alignment assembly 100.

[0042] When the perforated part 30 is aligned and pressed, the alignment component 100 extends axially and drives the pressing component 200 to extend into the alignment hole 301. At this time, the alignment component 100 and the alignment hole 301 cooperate to center-align the perforated part 30, so that the central axis of the alignment component 100 coincides with the central axis of the alignment hole 301. After alignment, the pressing component 200 moves relative to the alignment component 100 and extends out of the side of the alignment component 100. The pressing component 200 can abut against the inner wall of the alignment hole 301. At the same time, the alignment component 100 also fits against the inner wall of the alignment hole 301, realizing the pressing and fixing of the perforated part 30.

[0043] In the alignment assembly 100, the alignment drive 110 is the power source of the alignment assembly 100, and the alignment component 120 is the main component for aligning the perforated part 30. The alignment component 120 is disposed at the output end of the alignment drive 110, and the alignment drive 110 can output linear motion to drive the alignment component 120 to move axially, so that the alignment component 120 can extend or retract relative to the alignment drive 110.

[0044] When the alignment drive 110 drives the alignment component 120 to extend, the end of the alignment component 120 away from the alignment drive 110 can gradually extend into the alignment hole 301. The outer wall of the alignment component 120 is positioned opposite to the inner wall of the alignment hole 301, and the alignment component 120 and the alignment hole 301 cooperate to center the part 30 with the hole. When the alignment drive 110 drives the alignment component 120 to retract, the alignment component 120 can gradually move out of the alignment hole 301.

[0045] A clamping assembly 200 is disposed on an alignment member 120, which can drive the clamping assembly 200 to move into or out of the alignment hole 301. In the clamping assembly 200, a clamping drive member 210 serves as the power source and is disposed on the alignment member 120. A locking member 220 is a component for locking or unlocking the part 30 with the hole. The locking member 220 is rotatably disposed on the alignment member 120, and the clamping drive member 210 can output linear motion to abut or disengage from the locking member 220, causing the locking member 220 to abut or disengage from the inner wall of the alignment hole 301.

[0046] When the clamping drive 210 extends, it abuts against the locking member 220 and pushes the locking member 220 to move relative to the alignment member 120, so that one end of the locking member 220 extends out of the alignment member 120 and abuts against the inner wall of the alignment hole 301. At this time, the force of the locking member 220 abutting against the alignment hole 301 can push the alignment member 120 against the inner wall of the alignment hole 301. Through the abutment of the alignment member 120 and the locking member 220 against the inner wall of the alignment hole 301, the perforated part 30 is locked. When the clamping drive 210 retracts, the locking member 220 can be reset to disengage from the inner wall of the alignment hole 301, thereby unlocking the perforated part 30.

[0047] When the alignment and clamping mechanism 10 of this application aligns and clamps the perforated part 30, the alignment drive 110 drives the alignment component 120 to extend the clamping assembly 200. The end of the alignment component 120 away from the alignment drive 110 can gradually extend into the alignment hole 301. The outer wall of the alignment component 120 is opposite to the inner wall of the alignment hole 301. The alignment component 120 and the alignment hole 301 cooperate to center the perforated part 30. After alignment, when the clamping drive 210 extends, the clamping drive 210 can abut against the locking component 220 and push the locking component 220 to move relative to the alignment component 120, so that one end of the locking component 220 extends out of the alignment component 120 and abuts against the inner wall of the alignment hole 301. At this time, the force of the locking member 220 abutting against the alignment hole 301 can push the alignment component 120 against the inner wall of the alignment hole 301. By the alignment component 120 and the locking member 220 abutting against the inner wall of the alignment hole 301, the holed part 30 is locked.

[0048] In this way, the alignment and clamping of the perforated part 30 can be completed, and the processing equipment can process the perforated part 30. After the perforated part 30 is processed, the alignment and clamping mechanism 10 needs to release the perforated part 30. Specifically, the clamping drive 210 retracts to push the locking member 220. At this time, the locking member 220 can reset to disengage from the inner wall of the alignment hole 301, thereby unlocking the perforated part 30. Subsequently, the alignment drive 110 drives the alignment component 120 to retract the clamping assembly 200, and the alignment component 120 can gradually move out of the alignment hole 301, completing the release of the perforated part 30. That is, when the perforated part 30 is aligned and pressed, the perforated part 30 is first aligned with the center by the alignment component 100, and then the perforated part 30 is pressed and fixed by the pressing component 200. When the perforated part 30 is released, the perforated part 30 is first released by the pressing component 200, and then the alignment component 100 moves out of the alignment hole 301.

[0049] In the alignment and clamping mechanism 10 of the above embodiment, the clamping drive member 210 and the locking member 220 are disposed on the alignment component 120. After the alignment drive member 110 and the alignment component 120 are aligned with the center of the perforated part 30, the clamping drive member 210 and the locking member 220 clamp and fix the perforated part 30. In this way, the alignment and clamping mechanism 10 can realize the center alignment and clamping fixation of the perforated part 30, which is convenient for the subsequent production and processing of the perforated part 30. There is no need for separate alignment and clamping, which improves efficiency. At the same time, the alignment and clamping mechanism 10 has a simple structure and does not require external auxiliary devices, thus saving costs and space.

[0050] See Figure 3 and Figure 4 In one embodiment, the alignment component 120 includes an alignment shaft 121 and a guide shaft 122. One end of the alignment shaft 121 is connected to the alignment drive component 110, and the guide shaft 122 is disposed at the other end of the alignment shaft 121 and guides the alignment shaft 121 into the alignment hole 301. The alignment shaft 121 is the main shaft for the alignment component 120 to achieve alignment, and the guide shaft 122 is the structure for guiding the alignment component 120. One end of the alignment shaft 121 is connected to the output end of the alignment drive component 110, and the other end of the alignment shaft 121 is connected to the guide shaft 122.

[0051] When the alignment drive 110 drives the alignment component 120 to extend into the alignment hole 301, the guide shaft 122 acts as a guide, guiding the alignment shaft 121 into the alignment hole 301, facilitating the alignment of the alignment shaft 121 with the alignment hole 301. The clamping drive 210 is disposed on the alignment shaft 121, and the locking component 220 is movably disposed on the alignment shaft 121 and / or the guide shaft 122. After the alignment shaft 121 is aligned with the center of the perforated part 30, the locking component 220 abuts against the inner wall of the alignment hole 301. At this time, the force exerted by the locking component 220 against the inner wall of the alignment hole 301 can push the outer wall of the alignment shaft 121 to conform to the inner wall of the alignment hole 301. The clamping and fixing of the perforated part 30 is achieved through the locking component 220 and the alignment shaft 121 abutting against the inner wall of the alignment hole 301.

[0052] Optionally, the guide shaft 122 is tapered and has a large-diameter end and a small-diameter end. The large-diameter end of the guide shaft 122 is connected to the alignment shaft 121, and the small-diameter end is away from the alignment shaft 121, allowing the guide shaft 122 to easily extend into the alignment hole 301. Optionally, the alignment shaft 121 and the guide shaft 122 are an integral structure. Of course, in other embodiments of this application, the alignment shaft 121 and the guide shaft 122 can also be separately configured. Optionally, the edge of the guide shaft 122 away from the alignment shaft 121 is rounded.

[0053] See Figure 3 and Figure 4 In one embodiment, the longitudinal cross-sectional shape of the alignment component 120 is adapted to the longitudinal cross-sectional shape of the alignment hole 301, and a micro-gap exists between the outer wall of the alignment component 120 and the inner wall of the alignment hole 301. That is, the longitudinal cross-sectional shape of the alignment shaft 121 is adapted to the longitudinal cross-sectional shape of the alignment hole 301 to ensure the alignment effect of the perforated part 30. Here, the micro-gap refers to the small gap between the outer wall of the alignment shaft 121 and the inner wall of the alignment hole 301 after the alignment shaft 121 extends into the alignment hole 301.

[0054] Generally, after the alignment shaft 121 extends into the alignment hole 301, the outer wall of the alignment shaft 121 can contact the inner wall of the alignment hole 301. However, due to machining errors and assembly requirements, there is a certain gap between the outer wall of the alignment shaft 121 and the inner wall of the alignment hole 301. This gap will not affect the center alignment of the alignment shaft 121 with the hole part 30. Furthermore, after alignment, the locking member 220 abuts against the inner wall of the alignment hole 301. The force of the locking member 220 abutting against the alignment hole 301 can push the alignment shaft 121 in the opposite direction. The alignment shaft 121 can abut against the inner wall of the alignment hole 301 by moving a small distance, which will not affect the center alignment effect of the hole part 30.

[0055] In this embodiment, the longitudinal cross-sectional shape of the alignment shaft 121 is circular, and correspondingly, the longitudinal cross-sectional shape of the alignment hole 301 is also circular. Of course, in other embodiments of this application, the longitudinal cross-sectional shape of the alignment shaft 121 may also be elliptical or other shapes, and the longitudinal cross-sectional shape of the alignment hole 301 may be adapted to the longitudinal cross-sectional shape of the alignment shaft 121.

[0056] See Figure 3 and Figure 4 In one embodiment, one end of the alignment component 120 is detachably connected to the alignment drive component 110. That is, the alignment shaft 121 and the output end of the alignment drive component 110 are detachably connected. It is understood that the shape and / or size of the alignment hole 301 of different perforated parts 30 may differ. After the alignment drive component 110 and the alignment component 120 are detachably connected in this application, the alignment component 120 that matches the shape and / or size of the alignment hole 301 can be selected, and the alignment component 120 can be installed on the output end of the alignment drive component 110 to achieve the alignment of the corresponding perforated parts 30.

[0057] See Figures 2 to 5 In one embodiment of this application, the alignment drive 110 includes an alignment cylinder 111, an alignment piston 112, and an alignment piston rod 113. The alignment piston 112 is disposed in the alignment cylinder 111. One end of the alignment piston rod 113 is connected to the alignment piston 112, and the other end extends through the alignment cylinder 111 and is connected to the alignment component 120. Figure 5 for Figure 2 The diagram shows the alignment and clamping mechanism 10 aligning and clamping the perforated part 30, removing part of the part. In this embodiment, the alignment drive 110 is an alignment cylinder. The alignment cylinder is connected to the alignment component 120 to drive the alignment component 120 to move axially, so that the alignment component 120 can extend into or move out of the alignment hole 301 of the perforated part 30.

[0058] Specifically, the alignment cylinder 111 is the outer shell of the alignment drive 110, the alignment piston 112 is the sealing component in the alignment drive 110, and the alignment piston rod 113 is the output shaft of the alignment drive 110. One end of the alignment piston rod 113 is connected to the alignment drive 110, and the other end is connected to the alignment component 120. When the alignment piston 112 moves in the alignment cylinder 111, it can drive the alignment piston rod 113 to move axially, which in turn can drive the alignment component 120 to move axially, so that the alignment component 120 can extend into or move out of the alignment hole 301 of the perforated part 30, thereby realizing the center alignment operation of the perforated part 30.

[0059] See Figures 2 to 5In one embodiment, the alignment piston 112 divides the alignment cylinder 111 into a first chamber (not shown) and a second chamber (not shown). The alignment drive 110 further includes a first connector 114 communicating with the first chamber and a second connector 115 communicating with the second chamber. The first connector 114 or the second connector 115, through which driving fluid is introduced, can drive the alignment piston 112 to move the alignment component 120 into or out of the alignment hole 301 via the alignment piston rod 113. Optionally, the driving fluid is air, and the first connector 114 and the second connector 115 are air inlet and outlet connectors.

[0060] When the alignment clamping mechanism 10 performs the alignment operation, driving fluid is introduced into the first cavity through the first connector 114. The driving fluid can push the alignment piston 112 towards the second cavity to increase the volume of the first cavity. At this time, the alignment piston 112 drives the alignment component 120 to extend through the alignment piston rod 113. The alignment component 120 can gradually extend into the alignment hole 301 and cooperate with the alignment hole 301 to perform the alignment operation, realizing the alignment of the perforated part 30. After the clamping assembly 200 releases the perforated part 30, driving fluid is introduced into the second cavity through the second connector 115. The driving fluid can push the alignment piston 112 towards the first cavity to increase the volume of the second cavity. At this time, the alignment piston 112 drives the alignment component 120 to retract through the alignment piston rod 113. The alignment component 120 can gradually move out of the alignment hole 301.

[0061] Of course, in other embodiments of this application, the alignment drive 110 may also be an alignment hydraulic cylinder, or the alignment drive 110 may be a linear motor, the output shaft of which is connected to the alignment component 120. The linear motor can output linear motion to drive the alignment component 120 to extend into or move out of the alignment hole 301. Furthermore, a reducer is integrated into the linear motor.

[0062] See Figures 2 to 6 In one embodiment, the alignment member 120 has a mounting cavity 123 and a locking hole 124 extending radially into the mounting cavity 123. The pressing drive member 210 and the locking member 220 are located in the mounting cavity 123. The locking member 220 can extend or retract into the locking hole 124 to abut or disengage from the inner wall of the alignment hole 301. Figure 6 for Figure 3 A schematic diagram of the locking element 220 in the alignment and clamping mechanism 10 shown.

[0063] In other words, the alignment component 120 is hollow, and its internal cavity is the mounting cavity 123, in which the clamping drive component 210 and the locking component 220 are located. Thus, when the alignment component 120 drives the clamping assembly 200 to extend into or exit the alignment hole 301, the clamping assembly 200 will not touch the perforated part 30. Simultaneously, the outer wall of the alignment component 120 can align with the inner wall of the alignment hole 301, ensuring the alignment effect of the alignment component 120 on the perforated part 30.

[0064] Furthermore, the outer wall of the alignment component 120 also has a locking hole 124, which extends into the mounting cavity 123. When the locking member 220 moves in the mounting cavity 123, it can extend or retract through the locking hole 124. When the output end of the pressing drive member 210 extends, it can abut against the locking member 220 and push it to move, causing the locking member 220 to extend through the locking hole 124 and abut against the inner wall of the alignment hole 301, thereby locking the perforated part 30. After the pressing drive member 210 retracts, the locking member 220 can reset to disengage from the inner wall of the alignment hole 301 and retract into the locking hole 124.

[0065] It is worth noting that the locking hole 124 is an opening adapted to the shape of the locking member 220, or it can be an opening on the side of the aligning member 120. In this embodiment, the locking member 220 is rotatably disposed in the mounting cavity 123. The pressing drive member 210 abuts against or disengages from one end of the locking member 220, and the locking member 220 rotates so that its other end can extend or retract into the locking hole 124. Of course, in other embodiments of this application, the locking member 220 may also be slidably disposed in the mounting cavity 123. The locking member 220 is inclined relative to the central axis of the aligning member 120. The pressing drive member 210 abuts against or pushes one end of the locking member 220, and can push the locking member 220 to move, so that the other end of the locking member 220 abuts against or disengages from the inner wall of the aligning hole 301. This application only describes the locking member 220 as rotatably disposed as an example.

[0066] See Figures 2 to 6 In one embodiment, the locking element 220 includes a driving body 221 and a locking body 222. The driving body 221 is rotatably disposed in the mounting cavity 123, and the locking body 222 is disposed at one end of the driving body 221 and protrudes from the driving body 221. The pressing driving element 210 can push the driving body 221 to make the locking body 222 extend out of the locking hole 124 and abut against the inner wall of the alignment hole 301. Optionally, the driving body 221 is rotatably mounted in the mounting cavity 123 via a rotating shaft 250, and the locking body 222 is disposed at the end of the driving body 221 away from the pressing driving element 210, that is, the locking element 220 has a lever structure.

[0067] After the alignment component 120 aligns with the perforated part 30, the clamping drive component 210 extends and abuts against the drive body 221. The clamping drive component 210 continues to push the drive body 221, allowing the drive body 221 to rotate around the rotating shaft 250. This, in turn, causes the drive body 221 to rotate the locking body 222, enabling the locking body 222 to extend out of the locking hole 124 and abut against the inner wall of the alignment hole 301, thus locking the perforated part 30. When releasing the perforated part 30, the clamping drive component 210 retracts and disengages from the drive body 221. The drive body 221 then rotates the locking body 222 to reset, causing the locking body 222 to disengage from the inner wall of the alignment hole 301 and retract into the locking hole 124, thus unlocking the perforated part 30.

[0068] Optionally, the driving body 221 and the locking body 222 are an integral structure. Of course, in other embodiments of this application, the driving body 221 and the locking body 222 may also be separately configured.

[0069] See Figures 2 to 6 In one embodiment, the driving body 221 has a driving ramp 2211. The driving body 221 has the driving ramp 2211 at one end facing the pressing driving member 210. After the pressing driving member 210 abuts against the driving ramp 2211, the pressing driving member 210 continues to extend. Due to the action of the driving ramp 2211, the pressing driving member 210 can push the driving body 221 to rotate around the rotating shaft 250. As a result, when the driving body 221 rotates, it can drive the locking body 222 to extend out of the locking hole 124 to abut against the inner wall of the alignment hole 301.

[0070] See Figures 2 to 6 In one embodiment, the locking body 222 protrudes from the driving body 221 and has a locking arc surface 2221. That is, the surface of the locking body 222 protrudes from the surface of the driving body 221. Thus, when the driving body 221 drives the locking body 222 to rotate, the locking body 222 can easily extend out of the locking hole 124 through the protruding portion and abut against the inner wall of the alignment hole 301. Furthermore, the surface of the locking body 222 protruding from the driving body 221 is the locking arc surface 2221. The locking body 222 abuts against the inner wall of the alignment hole 301 through the locking arc surface 2221, facilitating the engagement of the locking body 222 with the inner wall of the alignment hole 301 to achieve the clamping and fixing of the perforated part 30.

[0071] Of course, in other embodiments of this application, the driving body 221 and the locking body 222 are locking cams. That is, the locking member 220 can also be a cam structure. In the locking member 220, the small end of the cam cooperates with the pressing driving member 210, and the large end can extend out of the locking hole 124 and abut against the inner wall of the alignment hole 301.

[0072] See Figures 2 to 6In one embodiment, the alignment component 120 further has a reset hole 125 extending into the mounting cavity 123. The clamping assembly 200 also includes a reset member 230, which is disposed in the reset hole 125 and extends into the mounting cavity 123. The reset member 230 can abut against the locking member 220, causing the locking member 220 to retract into the locking hole 124. After the clamping drive member 210 retracts, the reset member 230 can automatically reset the locking member 220, causing the locking member 220 to disengage from the inner wall of the alignment hole 301 and retract into the locking hole 124, thereby unlocking the perforated part 30.

[0073] Specifically, the reset member 230 is disposed in the reset hole 125 and connected to the drive body 221. When the pressing drive member 210 pushes the drive body 221, the drive body 221 can overcome the elastic force of the reset member 230 and rotate around the rotating shaft 250. This allows the drive body 221 to drive the locking body 222 to rotate, so that the locking body 222 can extend out of the locking hole 124 and abut against the inner wall of the alignment hole 301, thereby locking the perforated part 30. When the perforated part 30 is released, the alignment drive member 110 retracts and disengages from the drive body 221. The elastic force of the reset member 230 allows the drive body 221 to drive the locking body 222 to rotate and reset, so that the locking body 222 disengages from the inner wall of the alignment hole 301 and retracts into the locking hole 124, thereby unlocking the perforated part 30.

[0074] Optionally, the reset member 230 is a spring. In one embodiment, the clamping assembly 200 further includes a fixing member 240 disposed in the reset hole 125 to fix one end of the reset member 230 to the alignment member 120. This ensures that the reset member 230 accurately drives the locking member 220 to reset. Optionally, the fixing member 240 includes, but is not limited to, a locking screw.

[0075] See Figures 2 to 6 In one embodiment, the clamping drive 210 includes a clamping cylinder 211, a clamping piston (not shown), and a clamping piston rod 212. The clamping cylinder 211 is disposed in the mounting cavity 123, the clamping piston is disposed in the clamping cylinder 211, one end of the clamping piston rod 212 is connected to the clamping piston, and the other end can extend through the clamping cylinder 211 and abut against or disengage from the locking member 220. In this embodiment, the clamping drive 210 is a clamping cylinder. The extension and retraction movement of the clamping cylinder drives the locking member 220 to rotate, so that the locking body 222 can extend or retract the locking hole 124.

[0076] Specifically, the clamping cylinder 211 is the outer shell of the clamping drive 210, the clamping piston is the sealing component in the clamping drive 210, and the clamping piston rod 212 is the output shaft of the clamping drive 210. One end of the clamping piston rod 212 is connected to the clamping drive 210, and the other end of the clamping piston rod 212 can abut against or disengage from the locking component 220. When the clamping piston moves in the clamping cylinder 211, it can drive the clamping piston rod 212 to move axially, thereby pushing or disengaging the locking component 220, causing the locking body 222 to extend or retract into the locking hole 124, thus achieving the clamping and fixing of the perforated part 30.

[0077] Of course, in other embodiments of this application, the clamping drive 210 may also be a clamping hydraulic cylinder, or the clamping drive 210 may be a linear motor. The output shaft of the linear motor may abut or disengage from the locking member 220. The linear motor may output linear motion to drive the locking member 220 to rotate so that the locking body 222 extends or retracts from the locking hole 124. Furthermore, a reducer may be integrated into the linear motor.

[0078] See Figures 2 to 6 In one embodiment, the clamping drive 210 further includes a third connector 213, which is located outside the alignment drive 110 and passes through the alignment drive 110 to communicate with the clamping cylinder 211. The third connector 213 can allow or discharge driving fluid to drive the clamping piston to move the clamping piston rod 212 to abut against or disengage from the locking member 220. Optionally, the driving fluid is air, and the third connector 213 is an air inlet / outlet connector.

[0079] When the positioning and clamping mechanism 10 performs a clamping operation, driving fluid is introduced into the clamping drive 210 through the third connector 213. The driving fluid can push the clamping piston to move. At this time, the clamping piston drives the clamping piston rod 212 to extend. The end of the clamping piston rod 212 can abut against and push the locking member 220. The locking member 220 rotates so that the locking body 222 extends out of the locking hole 124 and abuts against the inner wall of the positioning hole 301, thereby clamping and fixing the perforated part 30. When releasing the perforated part 30, the driving fluid in the clamping drive 210 is discharged through the third connector 213. At this time, the clamping piston drives the clamping piston rod 212 to disengage from the locking member 220. The reset member 230 drives the locking member 220 to reset, so that the locking body 222 disengages from the inner wall of the positioning hole 301 and retracts into the locking hole 124.

[0080] During alignment and clamping, the alignment and clamping mechanism 10 of this application introduces driving fluid into the alignment drive member 110 through the first connector 114. The alignment piston 112 drives the alignment component 120 to extend through the alignment piston rod 113. The alignment component 120 gradually extends into the alignment hole 301. The alignment shaft 121 engages with the alignment hole 301 to center-align the perforated part 30, aligning the central axis of the alignment shaft 121 with the central axis of the alignment hole 301, thus achieving alignment of the perforated part 30. Subsequently, driving fluid is introduced into the clamping drive member 210 through the third connector 213. The clamping piston drives the clamping piston rod 212 to extend and abut against the locking member 220, pushing the locking member 220 to rotate. This causes the locking body 222 to extend out of the locking hole 124 and abut against the inner wall of the alignment hole 301, thus clamping and fixing the perforated part 30. At this time, the perforated part 30 can be processed.

[0081] After the perforated part 30 is processed, when the alignment clamping mechanism 10 needs to release the perforated part 30, the driving fluid in the clamping drive 210 is discharged through the third connector 213. At this time, the clamping piston drives the clamping piston rod 212 to disengage from the locking member 220, and the reset member 230 drives the locking member 220 to reset, so that the locking body 222 disengages from the inner wall of the alignment hole 301 and retracts into the locking hole 124, thereby unlocking the perforated part 30. Subsequently, driving fluid is introduced into the alignment drive 110 through the second connector 115, and the alignment piston 112 drives the alignment component 120 to retract through the alignment piston rod 113. The alignment component 120 gradually moves out into the alignment hole 301.

[0082] The alignment and clamping mechanism 10 of this application integrates the alignment component 100 and the clamping component 200, which can realize the center alignment and clamping fixation of the perforated part 30, which facilitates the subsequent production and processing of the perforated part 30. It eliminates the need for separate alignment and clamping, thus improving efficiency. At the same time, the alignment and clamping mechanism 10 has a simple structure and does not require external auxiliary devices, thereby saving costs and space.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
