Description

Technical Field

[0001] This utility model belongs to the field of process equipment technology, and in particular relates to a guide and limiting mechanism. Background Technology

[0002] Limiting mechanisms are widely used in process equipment manufacturing, primarily to control or restrict the range or position of an object's movement. However, existing limiting mechanisms suffer from several problems, such as complex structures, insufficient precision, and high costs. These issues not only increase manufacturing and maintenance costs but may also lead to higher system failure rates. Complex limiting mechanisms consist of multiple parts, making their structure difficult to simplify, while simpler limiting mechanisms have limitations in terms of precision and versatility, thus restricting their widespread application in industrial automation production.

[0003] Traditional closed-loop limit mechanisms typically require complex sensor systems and sophisticated control algorithms, which undoubtedly increases the cost and complexity of the system, thereby affecting its stability and reliability. Utility Model Content

[0004] This invention provides a guide and limiting mechanism to solve existing technical problems.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: A guide limiting mechanism includes a guide block and a contact block. The guide block is provided with a limiting screw and at least two guide posts. The limiting screw and guide posts both extend along the limiting direction. The limiting screw abuts against the contact block and can be adjusted to push the contact block. The contact block is connected to a plurality of guide posts and can move along the limiting direction.

[0006] As a further improvement to the above technical solution: The guide block is provided with a groove, which extends along the vertical limiting direction, and the contact block is movably inserted into the groove.

[0007] The groove is provided in two places and is located on both sides of the limiting screw. The contact block is movably inserted into the groove on both sides along the vertical limiting direction.

[0008] Each of the guide posts is respectively located in the grooves on both sides.

[0009] Each of the guide posts is provided with a spring, which is located on the side of the contact block away from the limiting screw. One end of the spring abuts against the contact block, and the other end of the spring abuts against the guide block.

[0010] The contact block is provided with multiple guide holes, and each guide hole is movably fitted onto a corresponding guide post.

[0011] The contact block is also provided with mounting holes, and a proximity switch is installed in the mounting holes.

[0012] The guide block is also provided with a clearance hole, through which the proximity switch passes.

[0013] The contact block is also provided with a limiting protrusion, which is located on the side close to the limiting fixture.

[0014] The limiting protrusion is located in the extending direction of the limiting screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By rationally configuring guide blocks, contact blocks, limit screws, and at least two guide posts, the advantages of simple structure, high precision, and low cost are achieved.

[0016] The limit screw and guide post extend along the limiting direction, enabling the contact block to move stably and accurately along the limiting direction, thus ensuring the accuracy and stability of the limiting.

[0017] The limit screw abuts against the contact block. By adjusting the position of the limit screw, the position of the contact block can be flexibly adjusted, thereby achieving precise positioning of the tooling.

[0018] The use of multiple guide posts ensures that the contact block is subjected to uniform force during movement, avoiding the problem of uneven force distribution caused by a single guide post, and further improving the stability and reliability of the limiting mechanism.

However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0027] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0028] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this invention can be purchased from the market or prepared by existing methods.

[0029] Example: Figures 1-4 As shown, the guide limiting mechanism of this embodiment includes a guide block 1 and a contact block 2. The guide block 1 is equipped with a limiting screw 3 and at least two guide posts 4. Both the limiting screw 3 and the guide posts 4 extend along the limiting direction. The limiting screw 3 abuts against the contact block 2 and can be adjusted relative to the guide block 1 to push the contact block 2. The contact block 2 is connected to multiple guide posts 4 and can move along the limiting direction. Through the reasonable configuration of the guide block 1, contact block 2, limiting screw 3, and at least two guide posts 4, the advantages of simple structure, high precision, and low cost are achieved. The limiting screw 3 and guide posts 4 extend along the limiting direction, enabling the contact block 2 to move stably and accurately along the limiting direction, ensuring the accuracy and stability of the limiting. The limiting screw 3 abuts against the contact block 2, and by adjusting the position of the limiting screw 3, the position of the contact block 2 can be flexibly adjusted, thereby achieving precise limiting of the tooling. The use of multiple guide posts 4 ensures that the contact block 2 is subjected to uniform force during movement, avoiding the problem of uneven force distribution caused by a single guide post, further improving the stability and reliability of the limiting mechanism. In addition, the entire mechanism has a simple structural design, few parts, and low manufacturing and maintenance costs. It is suitable for various limit requirements in industrial automation production. It not only has significant advantages in performance, but also has high economic benefits and application prospects.

[0030] In this embodiment, the guide block 1 is provided with a groove 5, which extends along the vertical limiting direction, and the contact block 2 is movably inserted into the groove 5. This design further enhances the stability and accuracy of the limiting mechanism. The groove 5 provides a fixed moving path for the contact block 2, ensuring that the contact block 2 will not deviate during its movement in the limiting direction. By inserting the contact block 2 into the groove 5, deviation of the movement trajectory caused by external forces or vibrations can be effectively avoided, thereby improving the accuracy and reliability of the limiting mechanism. The overall design is simple and has few parts, which helps to reduce manufacturing and maintenance costs, while improving the service life and durability of the mechanism. This structure is suitable for applications requiring high precision and can operate stably in complex industrial environments, possessing broad application prospects.

[0031] In this embodiment, two grooves 5 are provided, located on both sides of the limiting screw 3. The contact block 2 is movably inserted into the grooves 5 on both sides along the perpendicular limiting direction. This design allows the contact block 2 to move more stably under the push of the limiting screw 3. The two grooves 5, located on both sides of the limiting screw 3, provide double guidance for the contact block 2, ensuring that it does not deviate during movement. This not only improves the accuracy of the limiting but also enhances the stability of the overall structure. Through this design, the contact block 2 experiences more uniform force when moving in the grooves 5, reducing wear and friction and improving the durability and service life of the mechanism. The double groove 5 structure enables the limiting mechanism to maintain efficient operation in complex environments and is suitable for various industrial automation production scenarios. This design simplifies the structure and effectively improves performance and reliability, offering significant application advantages.

[0032] In this embodiment, each guide post 4 is disposed in the groove 5 on both sides. This design further improves the stability and accuracy of the limiting mechanism. Distributing the guide posts 4 in the grooves 5 on both sides makes the movement of the contact block 2 in the vertical limiting direction smoother and more precise. The distribution of multiple guide posts 4 in the grooves 5 ensures that the contact block 2 maintains a stable posture when pushed by the limiting screw 3, avoiding the uneven force distribution problem caused by a single guide post. This design not only enhances the structural stability of the limiting mechanism but also improves its durability, reduces wear and friction, and extends its service life. Furthermore, the combination of the double grooves 5 and the guide posts 4 makes the force on the contact block 2 more uniform during movement, further improving the limiting accuracy and reliability. This structural design is simple and efficient, suitable for various industrial automated production environments, and has significant application advantages and economic benefits.

[0033] In this embodiment, each guide post 4 is equipped with a spring 41. The spring 41 is located on the side of the contact block 2 away from the limiting screw 3. One end of the spring 41 abuts against the contact block 2, and the other end abuts against the guide block 1. This design allows the contact block 2 to return to its initial position more smoothly through the reaction force provided by the spring 41 while being pushed by the limiting screw 3. The spring 41 enhances the flexibility and response speed of the limiting mechanism, ensuring the accuracy and stability of the contact block 2 during the limiting process. In this way, the limiting mechanism can not only accurately control the movement range of the object, but also automatically reset after the external force disappears, improving the automation level and reliability of the system. This design simplifies the structure, reduces the wear and maintenance costs of parts, and improves the overall durability and service life. At the same time, the reaction force of the spring 41 makes the force on the contact block 2 more uniform during movement, effectively avoiding deviation and jamming. In summary, the design of this embodiment combines high efficiency, stability, and economy, and is suitable for various industrial automation application scenarios.

[0034] In this embodiment, the contact block 2 is provided with four guide holes 21, which are respectively located at the four corners of the contact block 2. Each guide hole 21 is movably fitted onto the corresponding guide post 4. This design further enhances the stability and accuracy of the limiting mechanism. The cooperation between the four guide holes 21 and the four guide posts 4 allows the contact block 2 to slide stably and accurately in the vertical limiting direction. By providing multiple guide holes 21 on the contact block 2 and movably fitting them onto the guide posts 4, the smoothness and consistency of the contact block 2 during movement are ensured. This design effectively avoids offset and swaying when the contact block 2 is pushed by the limiting screw 3, thereby improving the limiting accuracy. The tight cooperation between the guide holes 21 and the guide posts 4 not only enhances the stability of the mechanism but also reduces friction and wear, extending the service life of the equipment. This structural design is simple and efficient, reducing manufacturing and maintenance costs while improving the reliability and durability of the limiting mechanism, making it very suitable for various application scenarios in industrial automation production.

[0035] In this embodiment, the contact block 2 is also provided with a mounting hole 22, on which a proximity switch 221 is installed. This design allows the limiting mechanism to not only physically restrict the target position, but also to accurately detect and provide feedback on the target position through the proximity switch 221. The mounting hole 22 allows the proximity switch 221 to be securely fixed to the contact block 2, so that when the contact block 2 moves to a specific position, the proximity switch 221 can accurately detect and output a signal. This design greatly improves the automation and intelligence level of the limiting mechanism, enabling it to not only have physical limiting functions, but also monitor the target position in real time and provide feedback, which helps to improve the accuracy and reliability of the entire system. Through the signal output of the proximity switch 221, further control and adjustment of the equipment can be achieved, ensuring precise positioning and operation during the production process. This design, which combines mechanical limiting and electronic detection, maintains the simplicity of the structure while enhancing the functionality and adaptability of the system, making it suitable for various industrial automation production scenarios and possessing significant application value and prospects.

[0036] In this embodiment, the guide block 1 is also provided with a clearance hole 11, through which the proximity switch 221 passes. This design allows the proximity switch 221 to pass smoothly through the guide block 1 and be installed in the mounting hole 22 on the contact block 2. The clearance hole 11 provides a channel for the proximity switch 221, ensuring that the proximity switch 221 can accurately detect the position of the contact block 2 without being obstructed by the guide block 1. In this way, the proximity switch 221 can monitor and provide feedback on changes in the target position in real time during the coordinated movement of the guide block 1 and the contact block 2. Through the design of the clearance hole 11, the limiting mechanism not only achieves physical limiting but also enables position detection and signal feedback through the proximity switch 221, thereby improving the automation and intelligence level of the system. The clearance hole 11 ensures that the proximity switch 221 can be stably installed and operated without affecting the normal operation of other components. The overall design is both simple and efficient, helping to reduce manufacturing and maintenance costs while enhancing the functionality and reliability of the system, making it suitable for various industrial automation production environments.

[0037] In this embodiment, the proximity switch 221 passes through the clearance hole 11 of the guide block 1 and is fastened to the contact block 2. The contact block 2 is made to contact the tooling by the limit screw 3. The proximity switch 221 can detect and provide feedback on whether the contact block is clamped on the tooling. It has low cost and can provide feedback on the limit status.

[0038] In this embodiment, the contact block 2 is further provided with a limiting protrusion 23, which is located near the limiting fixture. The design of the limiting protrusion 23 enables the contact block 2 to more accurately perform the limiting function when in contact with the fixture. By providing a prominent contact point, the limiting protrusion 23 ensures that the contact block 2 has a more stable and reliable contact with the fixture when pushed to the designated position. This not only improves the accuracy of the limiting but also enhances the overall stability of the mechanism. By adding the limiting protrusion 23, the contact block 2 can more effectively transmit the force of the limiting screw 3, avoiding slippage or misalignment of the contact surface, thereby ensuring that the position of the fixture remains within the predetermined range. The limiting protrusion 23 cooperates with other parts of the contact block 2, making the entire limiting process smoother and more efficient. This design further improves the performance of the limiting mechanism, especially in industrial automation applications with high precision and high stability requirements, where it has significant advantages. The combination of structural simplicity and functional versatility makes the guide limiting mechanism of this embodiment not only easy to manufacture and maintain but also adaptable to various complex working environments and needs, with broad application prospects.

[0039] In this embodiment, the limiting protrusion 23 is located in the extending direction of the limiting screw 3. This design ensures that the contact block 2 can accurately engage with the limiting screw 3 during the limiting process, while the limiting protrusion 23 is stably positioned under the support of multiple guide posts 4. The placement of the limiting protrusion 23 in the extending direction of the limiting screw 3 helps to accurately transmit the force to the tooling when the limiting screw 3 pushes the contact block 2. In this way, the limiting protrusion 23 can effectively apply the necessary limiting pressure to the tooling, ensuring that the contact block 2 remains stable in the predetermined position. The support of multiple guide posts 4 keeps the contact block 2 stable during movement, avoiding skewing or vibration caused by uneven force. The accurate positioning design of the limiting protrusion 23 further enhances the limiting accuracy, making the limiting mechanism perform excellently in demanding industrial automation applications. This design combines precise positioning and stable support, improving the overall performance and reliability of the system.
