Description

Technical Field

[0001] This application relates to the field of tooling positioning technology, and in particular to a positioning structure and positioning method. Background Technology

[0002] Currently, positioning structures typically install positioning elements on the side of the carrier that needs positioning to achieve subsequent machining positioning. However, when machining on both sides is required, positioning elements must be installed on the other side of the carrier, resulting in slow operation and low accuracy. Summary of the Invention

[0003] To address the issues of slow repositioning speed and low accuracy, embodiments of this application provide a positioning structure and method with fast positioning speed and high accuracy.

[0004] This application provides a positioning structure, which includes a mounting component, two positioning components, a clamping component, and a connecting assembly. The mounting component has a through hole. Along a first direction, the two positioning components are respectively connected to both sides of the mounting component, and a portion of the positioning components can extend into the through hole. The clamping component is used to clamp either of the two positioning components to define the position of that positioning component. The connecting assembly is disposed within the through hole, and along the first direction, both ends of the connecting assembly are respectively connected to the two positioning components.

[0005] Understandably, a positioning element is provided at both ends of the mounting component so that both sides of the mounting component can be used for subsequent mating and positioning with the clamping element. When double-sided quick positioning is required, simply flip the mounting component over; there is no need to reinstall the positioning elements, saving time and ensuring high positioning accuracy.

[0006] In one embodiment, the connecting assembly includes two connectors, one end of which is connected to each other, and the other end of which is respectively connected to two positioning members. Thus, along a first direction, one end of the two connectors is connected to a positioning member, and the other end is connected to each other, enabling the two positioning members to connect and to be coaxial in the first direction, resulting in identical positioning with high accuracy.

[0007] In one embodiment, the connecting assembly further includes a guide member. Along the first direction, the guide member has a first end and a second end disposed opposite to each other. The first end of the guide member is connected to one of the two connecting members, and the second end of the guide member is connected to the other of the two connecting members. Thus, the connecting assembly with the guide member not only connects the two positioning members but also ensures that both positioning members are parallel to the first direction, resulting in higher accuracy and reliability for the two positioning members during subsequent positioning processes.

[0008] In one embodiment, the guide member is located within the through hole and extends along the first direction. A first end and a second end of the guide member are coaxially arranged. The first end is coaxially connected to one of the two connecting members, and the second end of the guide member is coaxially connected to the other of the two connecting members. Thus, the coaxial arrangement of the first and second ends ensures good coaxiality of the guide member. Simultaneously, the connecting members coaxially connected to the first and second ends also exhibit good coaxiality relative to the guide member, and the coaxiality between the two connecting members is also relatively good, thereby resulting in good coaxiality between the positioning members connected to the two connecting members.

[0009] In one embodiment, the guide member abuts against the wall of the through hole along a second direction, which intersects with the first direction. This restricts the displacement of the guide member in the second direction to prevent movement during use that could lead to inaccurate guidance and consequently, low positioning accuracy of the positioning member. Therefore, restricting the displacement of the guide member in the second direction improves the positioning accuracy of the positioning member.

[0010] In one embodiment, the connecting component can restrict the displacement of the positioning element in the first direction, the second direction, and the third direction, where the first direction, the second direction, and the third direction intersect each other. This restriction of the positioning element's displacement prevents it from moving during subsequent operations, ensuring accurate positioning and improving positioning precision.

[0011] In one embodiment, the positioning member is threadedly connected to the connecting assembly. Thus, the positioning member, threadedly connected to the connecting assembly, can be adjusted in the first direction according to actual conditions, while ensuring a good connection between the positioning member and the connecting assembly, resulting in a robust and reliable overall structure.

[0012] In one embodiment, the positioning member can be displaced by the mounting member along the first direction. Thus, when the positioning member is not connected to the connecting assembly, it can move along the first direction and connect to the connecting assembly. After the positioning member is connected to the connecting assembly, its displacement in the first direction can be further restricted by the mounting member, thereby ensuring the stability of the positioning member during subsequent use and improving its positioning accuracy.

[0013] In one embodiment, the positioning member includes a protrusion that abuts against the surface of the mounting member along the first direction. Thus, the protrusion of the positioning member abuts against the surface of the mounting member to limit the displacement of the positioning member in the first direction. After the positioning member is connected to the connecting assembly, the protrusion abuts against the surface of the mounting member, thereby limiting the displacement of the positioning member in the first direction, thereby improving the stability of the positioning member during subsequent use and improving the positioning accuracy of the positioning member.

[0014] This application also provides a positioning method, implemented using the positioning structure described above, which includes the following steps: The two positioning elements are connected to the mounting element via the connecting assembly, and the coaxiality between the two positioning elements is detected.

[0015] Connect one of the positioning elements to the clamping element.

[0016] When it is necessary to position the other side of the mounting component, the mounting component is flipped over and the other side is positioned.

[0017] Understandably, by connecting the two positioning components to the mounting component and checking their coaxiality, high positioning accuracy on both sides of the mounting component is ensured. Simultaneously, the positioning method allows the mounting component to be flipped for rapid positioning of the other side, improving positioning efficiency. Attached Figure Description

[0027] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a positioning structure 100, which includes a mounting component 1, two positioning components 2, a clamping component 3, and a connecting assembly 4. The mounting component 1 has a through hole 10.

[0028] For ease of reading, this application introduces the terms first direction Z, second direction X, and third direction Y to describe the embodiments of this application. The first direction Z, second direction X, and third direction Y can be three non-parallel straight lines in space; further, the first direction Z, second direction X, and third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Y as the Y-axis direction of the three-dimensional coordinate system.

[0029] Along the first direction Z, two positioning elements 2 are respectively connected to both sides of the mounting element 1, and part of the positioning element 2 can extend into the through hole 10. The clamping element 3 is used to clamp either of the two positioning elements 2 to limit the position of the positioning element 2. The connecting component 4 is disposed in the through hole 10, and along the first direction Z, both ends of the connecting component 4 are respectively connected to the two positioning elements 2.

[0030] In this embodiment, the mounting component 1 can be a carrier plate for supporting the workpiece to be processed. In actual production, the structural strength and rigidity of the mounting component 1 must be considered to ensure good performance during subsequent use. The positioning component 2 can be a positioning tie rod for zero-point positioning. The clamping component 3 can be a pneumatic chuck for clamping the positioning component 2 effectively. The clamping force applied by the clamping component 3 to the positioning component 2 must ensure that the position of the positioning component 2 clamped by the clamping component 3 does not change relative to the clamping component 3. When the position of the clamping component 3 itself is limited, the position of the positioning component 2 clamped by the clamping component 3 is also limited. A through hole 10 is provided on the mounting component 1 so that the positioning component 2 can extend into the through hole 10 and connect to both sides of the mounting component 1 along the first direction Z. The connecting assembly 4 is used to connect the two positioning components 2 and make them coaxial in the first direction Z, thereby making the double-sided positioning more accurate.

[0031] It is understandable that a positioning element 2 is provided at both ends of the mounting component 1 so that both sides of the mounting component 1 can be used for subsequent positioning with the clamping element 3. When double-sided quick positioning is required, simply flip the mounting component 1; there is no need to reinstall the positioning element 2, saving time and ensuring high positioning accuracy.

[0032] like Figures 3 to 5 As shown, in one embodiment, the connecting component 4 includes two connectors 41, one end of the two connectors 41 is connected to each other, and the other end of the two connectors 41 is respectively connected to two positioning members 2.

[0033] In this embodiment, the connector 41 can be a double-headed locking screw. Along the first direction Z, one end of each connector 41 is connected to another connector 41, and the other end is connected to the positioning member 2, so that the two positioning members 2 are connected by the connecting assembly 4.

[0034] It is understandable that, along the first direction Z, one end of the two connecting pieces 41 is connected to the positioning piece 2, and the other end is connected to each other, so that the two positioning pieces 2 can be connected, and the two positioning pieces 2 can be coaxial in the first direction Z, so that the two are positioned in the same way and with high accuracy.

[0035] In one embodiment, the positioning element 2 is threadedly connected to the connecting component 4.

[0036] In this embodiment, the connector 41 in the connecting assembly 4 can be a screw so that it can be threadedly connected to the positioning member 2. In this way, the positioning member 2, which is threadedly connected to the connecting assembly 4, can be adjusted in the first direction Z according to the actual situation. At the same time, the positioning member 2 and the connecting assembly 4 are well connected, and the whole is firm and reliable.

[0037] It is understandable that, along the first direction Z, the end faces of the two positioning parts 2 that are close to each other can be provided with threaded holes, and the two ends of the two connecting parts 41 that are far apart are respectively threaded into the threaded holes provided by the two positioning parts 2.

[0038] In one embodiment, the connecting component 4 further includes a guide 42 along a first direction Z. The guide 42 has a first end 420 and a second end 421 disposed opposite to each other. The first end 420 of the guide 42 is connected to one of the two connecting components 41, and the second end 421 of the guide 42 is connected to the other connecting component 41.

[0039] In this embodiment, the guide member 42 can be a guide sleeve, and its structure is generally a hollow cylindrical structure with open ends. The inner circumferential surface of the guide member 42 is threaded so that the ends of the two connecting members 41 away from the positioning members 2 they are connected to can extend into the guide member 42, and the portion of the connecting member 41 extending into the guide member 42 is threadedly connected to the guide member 42, so as to lock the two connecting members 41 through the guide member 42. The guide member 42 can improve the coaxiality of the two positioning members 2 connected to the connecting assembly 4, and no further restrictions are imposed here. Along the first direction Z, the two ends of the guide member 42 are respectively the first end 420 and the second end 421, and the two ends are respectively connected to the two connecting members 41 to guide the two connecting members 41, thereby guiding the positioning members 2 connected to the two connecting members 41.

[0040] It is understandable that the connecting assembly 4 with the guide 42 can not only connect the two positioning pieces 2, but also make the two positioning pieces 2 parallel to the first direction Z, so that the two positioning pieces 2 have high accuracy and reliability in the subsequent positioning process.

[0041] In one embodiment, the guide member 42 is located inside the through hole 10. The guide member 42 extends along the first direction Z. The first end 420 and the second end 421 of the guide member 42 are coaxially arranged. The first end 420 is coaxially connected to one of the two connectors 41, and the second end 421 of the guide member 42 is coaxially connected to the other connector 41.

[0042] In this embodiment, the guide member 42 can be connected to the mounting member 1 to fix the guide member 42. The guide member 42 extends along the first direction Z and is parallel to the first direction Z as a whole. At the same time, its first end 420 and second end 421 are coaxially arranged. The two connecting members 41 are also coaxially connected to the guide member 42, so that the two positioning members 2 connected to the two connecting members 41 respectively can also be coaxial, thereby enabling the positioning of the two positioning members 2 to be the same and have good accuracy.

[0043] It is understandable that the coaxial arrangement of the first end 420 and the second end 421 ensures good coaxiality of the guide member 42. At the same time, the connector 41 coaxially connected to the first end 420 and the second end 421 also has good coaxiality relative to the guide member 42, and the coaxiality between the two connectors 41 is also relatively good, thereby making the coaxiality between the positioning member 2 connected to the two connectors 41 good.

[0044] In one embodiment, along the second direction X, the guide 42 abuts against the wall of the through hole 10.

[0045] In this embodiment, the sidewall of the guide member 42 along the second direction X can abut against the wall of the through hole 10 so that the displacement of the guide member 42 in the second direction X is restricted.

[0046] Understandably, the displacement of the guide member 42 in the second direction X is restricted to prevent the guide member 42 from moving during use and causing inaccurate guidance, thereby resulting in low positioning accuracy of the positioning member 2. Therefore, restricting the displacement of the guide member 42 in the second direction X can improve the positioning accuracy of the positioning member 2.

[0047] In addition, the guide member 42 can be fixed in the through hole 10 by welding or interference fit to ensure that the position of the guide member 42 relative to the mounting member 1 will not shift during the product processing.

[0048] In one embodiment, the connecting component 4 can limit the displacement of the positioning member 2 in the first direction Z, the second direction X, and the third direction Y.

[0049] In this embodiment, the connecting component 4 is fixedly connected to the positioning component 2 to limit the displacement of the positioning component 2 in the first direction Z, the second direction X, and the third direction Y, thereby further improving the positioning accuracy of the positioning component 2. The connecting component 41 in the connecting component 4 can be a screw, which is threadedly connected to the positioning component 2, thereby enabling a fixed connection and limiting the displacement of the positioning component 2.

[0050] It is understandable that limiting the displacement of positioning component 2 ensures that it will not move during subsequent operations, thereby guaranteeing accurate positioning and improving positioning precision.

[0051] In one embodiment, the positioning member 2 can be displaced by the mounting member 1 along the first direction Z.

[0052] It is understandable that when the positioning element 2 is not connected to the connecting component 4, the positioning element 2 can move along the first direction Z and connect to the connecting component 4. After the positioning element 2 is connected to the connecting component 4, the positioning element 2 can be further restricted by the mounting element 1 to the displacement in the first direction Z, thereby ensuring the stability of the positioning element 2 during subsequent use and thus improving the positioning accuracy of the positioning element 2.

[0053] In one embodiment, the positioning member 2 includes a protrusion 20 along a first direction Z, the protrusion 20 being able to abut against the surface of the mounting member 1.

[0054] In this embodiment, the outer contour of the projection of the protrusion 20 of the positioning member 2 onto the projection plane parallel to the second direction X and the third direction Y exceeds the outer contour of the through hole 10 on the projection plane. Therefore, the protrusion 20 of the positioning member 2 cannot extend into the through hole 10, and it can abut against the surface of the mounting member 1 along the first direction Z.

[0055] Understandably, the protrusion 20 of the positioning member 2 can abut against the surface of the mounting member 1 to limit the displacement of the positioning member 2 in the first direction Z. After the two positioning members 2 are connected to the connecting assembly 4, the two protrusions 20 of the two positioning members 2 abut against the two opposite surfaces of the mounting member 1 in the first direction Z, thereby completely limiting the positioning member 2 in the first direction Z, thereby improving the stability of the positioning member 2 in subsequent use and improving the positioning accuracy of the positioning member 2.

[0056] like Figure 6 As shown, this application embodiment also provides a positioning method 200, implemented using the positioning structure 100 described above, which includes the following steps: S1: Connect the two positioning parts 2 to the mounting part 1 through the connecting component 4, and check the coaxiality between the two positioning parts 2.

[0057] S2: Connect one of the positioning parts 2 to the clamping part 3.

[0058] S3: When it is necessary to position the other side of the mounting part 1, flip the mounting part 1 and position the other side.

[0059] In this embodiment, when detecting the coaxiality between the two positioning members 2, the coaxiality between the two positioning members 2 is within 0.002~0.003. After connecting the positioning member 2 to the clamping member 3, quick positioning and locking can be achieved through the positioning structure 100. The clamping member 3 can also be connected to or not connected to the positioning member 2 depending on the actual situation. When multi-face positioning is required, it is only necessary to flip the mounting member 1.

[0060] Understandably, by connecting the two positioning components 2 to the mounting component 1 and checking their coaxiality, high positioning accuracy on both sides of the mounting component 1 can be ensured. Simultaneously, the positioning method allows the mounting component 1 to be flipped over for rapid positioning of the other side, improving positioning efficiency.

[0061] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
