Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning technology, and in particular to an anti-rotation and alignment mechanism. Background Technology

[0002] In some machining processes, a positioning mechanism is generally used to fix the workpiece to be processed in order to facilitate subsequent processing. The positioning mechanism generally includes a frame and two sets of cylinders arranged opposite each other. The moving ends of the two sets of cylinders are equipped with components for fixing the workpiece to be processed. The two sets of cylinders move towards each other until the workpiece to be processed is clamped, thus completing the positioning.

[0003] However, if the workpiece to be processed is a cylinder or other easily rotatable workpiece, and the machining process has high requirements for the angle of the workpiece, the existing positioning mechanism cannot meet the requirements. This is because when the two sets of cylinders move in opposite directions, the workpiece to be processed will inevitably rotate or be displaced, and cannot enter the processing state at a specific angle. Even if the two sets of cylinders clamp the workpiece to be processed, the workpiece to be processed may still be displaced, resulting in the angle not being able to be fixed accurately, which in turn reduces the processing accuracy and may even require rework, which is a great waste of manpower and resources.

[0004] Therefore, it is urgent to propose a solution to the above problems. Utility Model Content

One end of the alignment part away from the limiting part can extend into the guide groove and can be engaged in the alignment groove. The limiting part is connected to the elastic element, and the threaded hole is provided at one end of the limiting part away from the alignment part.

[0012] In some embodiments, the actuating element includes a threaded rod portion and a mounting portion connected together, the diameter of the threaded rod portion being smaller than the diameter of the mounting portion, the mounting portion being rotatably mounted in the third cavity portion, and the threaded rod portion being located in the second cavity portion and engaging with the threaded hole.

[0013] In some embodiments, a handwheel is provided at the end of the operating member away from the alignment pin, and the handwheel is coaxially connected to the alignment pin.

[0017] In some embodiments, the guide member has a notch along the moving direction of the alignment pin, and the notch is connected to the guide groove.

[0018] The beneficial effects of this utility model are:

[0019] This utility model proposes an anti-rotation alignment mechanism for positioning a workpiece. The workpiece has an alignment groove along its length. The anti-rotation alignment mechanism includes a mounting frame, a first cylinder, and a second cylinder. The first and second cylinders are mounted at both ends of the mounting frame. The movable end of the first cylinder is used to fix the workpiece, and the movable end of the second cylinder has a fastener. The movable ends of the first and second cylinders can move towards each other so that the fastener presses against the workpiece. The anti-rotation alignment mechanism also includes an alignment component, which is mounted on the movable end of the second cylinder and located on the side of the fastener closest to the workpiece. The aligning component includes a guide, a aligning pin, and an operating component. The guide has a guide groove along the direction of movement of the movable end of the second cylinder, which is used for the workpiece to be processed to pass through. A movable cavity is provided on one side of the guide and is connected to the guide groove. The aligning pin is movably disposed in the movable cavity, and an elastic element is also provided in the movable cavity. The first end of the aligning pin can enter the guide groove and can be engaged in the aligning groove. The second end of the aligning pin is connected to the elastic element and has a threaded hole. The operating component is rotatably disposed in the movable cavity and has an external thread at one end. The external thread cooperates with the threaded hole. Rotation of the operating component can cause the aligning pin to enter or exit the guide groove.

[0020] The movable end of the second cylinder has a fastener, and the movable end of the first cylinder is fitted with a workpiece to be processed. When the movable ends of the first and second cylinders move towards each other, the fastener can press against the workpiece to be processed for fixation. In this embodiment, a alignment component is provided. The guide member of the alignment component has a guide groove along the movement direction of the movable end of the second cylinder. When the first cylinder drives the workpiece to be processed to move, the workpiece can pass through the guide groove. The guide groove provides a general guiding effect on the workpiece. Furthermore, a movable cavity is opened on one side of the guide member, and an alignment pin is movably installed in the movable cavity. When the operating member rotates, the alignment pin... The alignment pin can extend into the guide groove and engage with the alignment groove. This design ensures that the alignment pin engages with the workpiece before the fastener contacts it. Since the alignment groove extends along the length of the workpiece, the workpiece will not rotate as it continues to move towards the fastener after the alignment pin engages, maintaining a fixed angle. Once the fastener presses against the workpiece, rotating the control element causes the alignment pin to continue moving towards the workpiece, further securing it and preventing rotation during processing. This further ensures the accuracy and stability of the workpiece's positioning. Furthermore, this embodiment also incorporates an elastic element connected to the second end of the alignment pin. This elastic element generates a preload force on the alignment pin after it moves, improving its movement stability and positioning stability. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This embodiment proposes an anti-rotation and alignment mechanism to solve the problem of inaccurate positioning of the workpiece in the prior art.

[0033] like Figures 1-3As shown, an anti-rotation alignment mechanism is used to position a workpiece 100 to be processed. The workpiece 100 to be processed has an alignment groove along its own length. The anti-rotation alignment mechanism includes a mounting frame, a first cylinder 1 and a second cylinder 2. The first cylinder 1 and the second cylinder 2 are mounted at both ends of the mounting frame. The movable end of the first cylinder 1 is used to fix the workpiece 100 to be processed. The movable end of the second cylinder 2 has a fastener 3. The movable ends of the first cylinder 1 and the second cylinder 2 can move towards each other so that the fastener 3 presses against the workpiece 100 to be processed.

[0034] The anti-rotation alignment mechanism also includes an alignment component 4, which is installed on the movable end of the second cylinder 2 and located on the side of the fastener 3 near the workpiece 100 to be processed. The alignment component 4 includes a guide 41, an alignment pin 42, and an operating component 44. The guide 41 has a guide groove 411 along the movement direction of the movable end of the second cylinder 2, which is used for the workpiece 100 to be processed to pass through. A movable cavity 412 is provided on one side of the guide 41, which communicates with the guide groove 411. The alignment pin 42 is movably disposed in the movable cavity 412, and the movable cavity 412 is also provided with an elastic element 43. The first end of the alignment pin 42 can enter the guide groove 411 and can be locked into the alignment groove. The second end of the alignment pin 42 is connected to the elastic element 43. The second end of the alignment pin 42 is also provided with a threaded hole. The operating element 44 is rotatably disposed in the movable cavity 412 and has an external thread at one end. The external thread cooperates with the threaded hole. The rotation of the operating element 44 can cause the alignment pin 42 to enter or exit the guide groove 411.

[0035] Understandably, the movable end of the second cylinder 2 has a fastener 3, and the movable end of the first cylinder 1 is fitted with a workpiece 100 to be processed. When the movable ends of the first cylinder 1 and the second cylinder 2 move toward each other, the fastener 3 can press against the workpiece 100 to be processed for fixation. In this embodiment, a alignment component 4 is provided. The guide member 41 of the alignment component 4 has a guide groove 411 along the movement direction of the movable end of the second cylinder 2. When the first cylinder 1 drives the workpiece 100 to be processed to move, the workpiece 100 can pass through the guide groove 411. The guide groove 411 provides a general guiding effect on the workpiece 100. Furthermore, a movable cavity 412 is provided on one side of the guide member 41. An alignment pin 42 is movably disposed in the movable cavity 412. When the operating member 44... During rotation, the alignment pin 42 can extend into the guide groove 411 and engage with the alignment groove. With this setting, before the fastener 3 contacts the workpiece 100 to be processed, the alignment pin 42 extends into the guide groove 411 and engages with the alignment groove. Since the alignment groove extends along the length of the workpiece 100 to be processed, the workpiece 100 to be processed will not rotate itself when it continues to move toward the fastener 3 after the alignment pin 42 engages with the alignment groove, thus ensuring that its angle is fixed. When the fastener 3 presses against the workpiece 100 to be processed, the operating member 44 is rotated to make the alignment pin 42 continue to move toward the workpiece 100 to be processed, thereby pressing the workpiece 100 to be processed against it, preventing the workpiece 100 to be processed from rotating during processing, and further ensuring the positioning accuracy and firmness of the workpiece 100 to be processed. In addition, this embodiment also provides an elastic element 43, which is connected to the second end of the alignment pin 42. After the alignment pin 42 moves, it can generate a certain preload force on the alignment pin 42, thereby improving the movement stability and positioning stability of the alignment pin 42.

[0036] For example, the elastic element 43 is a spring, which is sleeved on the second end of the alignment pin 42. The spring is inexpensive and has a long-lasting elastic force, which improves the reliability of the anti-rotation alignment mechanism.

[0037] In some optional embodiments, the alignment component 4 further includes a mounting member 47, which is mounted on the movable end of the second cylinder 2, and a guide member 41 is mounted on the mounting member 47. This arrangement, by mounting the guide member 41 on the movable end of the second cylinder 2 through the mounting member 47, improves the structural rationality of the anti-rotation alignment mechanism.

[0038] In some optional embodiments, the movable cavity 412 includes a first cavity, a second cavity, and a third cavity connected in sequence. The first cavity is connected to the guide groove 411, and the third cavity is connected to the outside of the movable cavity 412. The diameter of the second cavity is larger than the diameters of the first and third cavities. The elastic element 43 is disposed in the second cavity, and the operating element 44 is rotatably disposed in the third cavity. This arrangement optimizes the spatial layout of the movable cavity 412, ensuring the stable installation of the alignment pin 42, the elastic element 43, and the operating element 44, while also improving the space utilization of the guide element 41, thereby enhancing the structural rationality of the anti-rotation alignment mechanism.

[0039] In some optional embodiments, the alignment pin 42 includes an alignment part and a limiting part connected together. The diameter of the limiting part is larger than the diameter of the alignment part. The alignment part is located in the first cavity, and the limiting part is located in the second cavity. The end of the alignment part away from the limiting part can extend into the guide groove 411 and can be engaged in the alignment groove. The limiting part is connected to the elastic member 43, and the end of the limiting part away from the alignment part has a threaded hole. This arrangement restricts the alignment part from disengaging from the movable cavity 412 through the limiting part, and the larger diameter of the limiting part improves the connection stability with the elastic member 43 and the operating member 44, thereby improving the structural rationality of the anti-rotation alignment mechanism.

[0040] In some optional embodiments, the operating member 44 includes a threaded rod portion and a mounting portion connected together. The diameter of the threaded rod portion is smaller than the diameter of the mounting portion. The mounting portion is rotatably mounted in the third cavity, and the threaded rod portion is located in the second cavity and mates with the threaded hole. The smaller diameter of the threaded rod portion reduces the opening size of the threaded hole, thereby avoiding affecting the structural strength of the alignment pin 42. A larger diameter mounting portion makes rotation easier, improving the user experience of the anti-rotation alignment mechanism.

[0041] In some optional embodiments, a handwheel 45 is provided at the end of the operating member 44 away from the alignment pin 42, and the handwheel 45 is coaxially connected to the alignment pin 42. This arrangement improves the effort-saving nature of the operating member 44 through the handwheel 45, thereby improving the user experience of the anti-rotation alignment mechanism.

[0042] In some alternative embodiments, the rim of the handwheel 45 is provided with a grip 46 for rotation. This arrangement further enhances the ease of operation of the control member 44, thereby improving the usability of the anti-rotation and alignment mechanism.

[0043] In some optional embodiments, the radial cross-section of the guide groove 411 is circular, and the guide member 41 is provided with a plurality of through holes 413 spaced apart, all of which communicate with the guide groove 411. This arrangement improves the fit between the guide groove 411 and the workpiece 100 to be processed, and the through holes 413 facilitate observation from different angles to see whether the alignment pin 42 is properly engaged with the workpiece 100 to be processed, thereby improving the reliability of the anti-rotation alignment mechanism.

[0044] In some alternative embodiments, the multiple through holes 413 are elongated holes that extend along the direction of movement of the movable end of the second cylinder 2. This arrangement widens the field of view of the through holes 413, making it easier to observe whether the alignment pin 42 is properly engaged with the workpiece 100 to be processed.

[0045] In some optional embodiments, the guide member 41 has a notch 414 along the direction of movement of the alignment pin 42, and the notch 414 is connected to the guide groove 411. This arrangement not only reduces the weight of the guide member 41, but also facilitates observation of the shape of the workpiece 100 to be processed through the notch 414 to determine whether the alignment pin 42 is properly engaged with the workpiece 100 to be processed.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
