Description

Technical Field

[0001] This utility model belongs to the field of quick replacement technology for precision hole guide sleeves, and in particular relates to a quick replacement guide sleeve device for precision hole machining of hardware parts. Background Technology

[0002] Quick-change precision hole guide sleeves are a common requirement in industrial equipment, especially in high-precision machining processes, to improve production efficiency and reduce equipment downtime. The quick-change design allows the production line to complete the task rapidly and efficiently when replacement is needed, reducing human intervention time and errors.

[0003] According to the published quick-change guide device (Announcement No.: CN201012453Y), its main structure is as follows: a quick-change guide plate is added to a fixed guide plate. The quick-change guide plate is mounted on the fixed guide plate via a support and a cylindrical pin. A cotter pin is fitted on the cylindrical pin, and one end of the quick-change guide plate forms a small angle. In use, simply flipping or lowering the quick-change guide plate allows for switching the guide for the parts. When the quick-change guide plate is flipped up, the small angle at the contact point with the fixed guide plate ensures that it will not fall down on its own during use, ensuring the reliability of the quick-change guide device. The cotter pin on the cylindrical pin prevents it from dislodging. This utility model is simple, quick, and labor-saving to operate.

[0004] The aforementioned patent achieves the effect of quick-change guide plate not falling down by the cooperation of components such as fixed guide plate and quick-change guide plate, which is simple, fast and labor-saving. However, it cannot achieve the effect of one-click quick disassembly and assembly of guide sleeve, and solve the problem of the traditional need to use additional tools and the time and downtime of a lot of replacement operations. Therefore, we have proposed a quick-change guide sleeve device for precision hole machining of hardware parts. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-change guide sleeve device for precision hole machining of hardware parts. The quick-change guide sleeve device solves the problems of the traditional method that requires additional tools and a large number of replacement operations, as well as the time and downtime.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a quick-change guide sleeve device for precision hole machining of hardware parts, including a base, an operating table fixedly connected to the top of the base, a sliding frame fixedly connected to the top of the operating table, a fixed frame slidably connected to the side of the sliding frame, a rotating mechanism fixedly connected to the side of the fixed frame, a control area provided on the side of the base, an on / off switch provided on the side of the control area, an adjustment key provided on the side of the control area, a connecting end fixedly connected to one end of the rotating mechanism, and a quick-change guide sleeve device provided on the inner side of the connecting end.

[0008] The quick-change guide sleeve device includes a slot formed on the circumferential surface of the connecting end. A push rod is slidably connected to the inner side of the slot, and a connecting sleeve is slidably connected to the inner side of the connecting end. A guide sleeve is fixedly connected to one end of the connecting sleeve. A groove is formed on the circumferential surface of the connecting sleeve, and a compression spring is fixedly connected to the inner side of the groove. A locking pin is fixedly connected to one end of the compression spring. This quick-change guide sleeve device, through the cooperation of sliding, compression spring, and locking pin, ensures that the guide sleeve can be replaced quickly and effectively, reducing equipment downtime and improving maintenance efficiency.

[0009] Furthermore, the inner surface of the slot is located on the displacement trajectory of the locking post, and one end of the locking post is located on the displacement trajectory of the top rod. The design of the slot and the displacement trajectories of the locking post and top rod ensures the coordinated cooperation between the components, enabling the guide sleeve to complete the replacement operation smoothly and quickly, increasing the stability of the device and the accuracy of operation.

[0010] Furthermore, the diameter of the retaining pin is the same as the diameter of the slot. This design, where the retaining pin and slot diameters are the same, ensures precise fit between components, smooth operation, and long-term stability of the device.

[0011] Furthermore, the initial state of the compression spring is relaxed. This relaxed initial state design allows the device to remain stable when not in operation, reducing unnecessary stress and wear, while providing a smooth mechanical transition during startup, ensuring the efficiency and long-term reliability of the device during operation.

[0012] Furthermore, a quick-release device is provided on the inner side of the connecting end. The quick-release device includes a return spring, one end of which is fixedly connected to the top inner side of the connecting end, and the other end of which is fixedly connected to a circular push plate. This quick-release device design ensures smooth, automated, and safe operation of the equipment, reduces the complexity of manual operation, and improves overall efficiency and long-term stability of the equipment.

[0013] Furthermore, the circumferential surface of the circular push plate is slidably connected to the inner surface of the connecting end. The main function of the slidable connection between the circular push plate and the connecting end is to provide smooth movement and precise guidance.

[0014] Furthermore, one end of the connecting sleeve is located on the displacement trajectory of the circular push plate. The main function of this connection sleeve being located on the displacement trajectory of the circular push plate is to push the connecting sleeve out through the circular push plate, thereby causing the guide sleeve to pop out.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves one-click quick installation and removal of guide sleeves through a quick guide sleeve replacement device. When installing a new guide sleeve, it can be directly inserted and automatically locked by compression springs and locking pins. The entire process requires no additional tools, significantly reducing the steps and time of replacement operations, effectively reducing equipment downtime, and improving the production efficiency of precision hole machining for hardware parts.

[0017] 2. This utility model, through the cooperation of components such as a reset spring and a circular push plate, enables the old guide sleeve to be automatically ejected by simply triggering the locking pin with a push rod during replacement, driven by the reset spring. This reduces the reliance on specialized tools and complex skills, thereby lowering labor costs and operational difficulty.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a quick-change guide sleeve device for precision hole machining of hardware parts, including a base 1, an operating table 2 fixedly connected to the top of the base 1, a sliding frame 3 fixedly connected to the top of the operating table 2, a fixed frame 4 slidably connected to the side of the sliding frame 3, a rotating mechanism 5 fixedly connected to the side of the fixed frame 4, a control area 6 provided on the side of the base 1, an on / off switch 7 provided on the side of the control area 6, an adjustment key 8 provided on the side of the control area 6, a connecting end 9 fixedly connected to one end of the rotating mechanism 5, and a quick-change guide sleeve device 10 provided on the inner side of the connecting end 9.

[0029] The guide sleeve quick-change device 10 includes a slot 101 formed on the circumferential surface of the connecting end 9. A push rod 102 is slidably connected to the inner side of the slot 101, and a connecting sleeve 103 is slidably connected to the inner side of the connecting end 9. A guide sleeve 104 is fixedly connected to one end of the connecting sleeve 103. A groove 105 is formed on the circumferential surface of the connecting sleeve 103, and a compression spring 106 is fixedly connected to the inner side of the groove 105. A locking post 107 is fixedly connected to one end of the compression spring 106. This guide sleeve quick-change device 10, through the cooperation of sliding, compression spring 106, and locking post 107, ensures that the guide sleeve 104 can be replaced quickly and effectively, reducing equipment downtime and improving maintenance efficiency.

[0030] The inner side of the slot 101 is located on the displacement trajectory of the locking post 107, and one end of the locking post 107 is located on the displacement trajectory of the push rod 102. The design of the displacement trajectories of the slot 101, locking post 107, and push rod 102 ensures the coordinated cooperation between the components, enabling the guide sleeve 104 to complete the replacement operation smoothly and quickly, increasing the stability of the device and the accuracy of operation.

[0031] The diameter of the locking post 107 is the same as the diameter of the slot 101. The design that the diameters of the locking post 107 and the slot 101 are the same ensures the precise fit of the components, smooth operation, and long-term stability of the device.

[0032] The initial state of the compression spring 106 is relaxed. This relaxed initial state design allows the device to remain stable when not in operation, reducing unnecessary stress and wear, while providing a smooth mechanical transition during startup, ensuring the efficiency and long-term reliability of the device during operation.

[0033] A quick ejection device 11 is provided on the inner side of the connecting end 9. The quick ejection device 11 includes a return spring 111, one end of which is fixedly connected to the top inner side of the connecting end 9, and the other end of which is fixedly connected to a circular push plate 112. This quick ejection device 11 design ensures smooth operation, automation, and safety of the equipment, reduces the complexity of manual operation, and improves overall efficiency and long-term stability of the equipment.

[0034] The circumferential surface of the circular push plate 112 is slidably connected to the inner surface of the connecting end 9. The main function of the sliding connection between the circular push plate 112 and the connecting end 9 is to provide smooth movement and precise guidance.

[0035] One end of the connecting sleeve 103 is located on the displacement trajectory of the circular push plate 112. The main function of the connecting sleeve 103 is to push the connecting sleeve 103 out through the circular push plate 112, thereby pushing the guide sleeve 104 to pop out.

[0036] A specific application of this embodiment is as follows: Before the device is started, the guide sleeve 104 is fixed in the connecting end 9 by the connecting sleeve 103. At this time, the compression spring 106 is in a relaxed state, and the locking pin 107 is partially embedded in the groove 105 of the connecting sleeve 103 under the action of the compression spring 106. At the same time, one end of the locking pin 107 is located in the slot 101, thereby locking the connecting sleeve 103 and the guide sleeve 104 in the connecting end 9. The operator manually operates the push rod 102, pushing the push rod 102 to slide inward along the slot 101. The push rod 102 pushes the locking pin 107, causing the locking pin 107 to overcome the elastic force of the compression spring 106 and move into the groove 105, thereby completely exiting the slot 101. The separation of the locking pin 107 from the slot 101 releases the locking of the connecting sleeve 103. At the same time, the device is quickly ejected. 11. Automatic activation: The reset spring 111 is released from the compressed state, pushing the circular push plate 112 to slide along the inner side of the connecting end 9. The displacement of the circular push plate 112 directly acts on one end of the connecting sleeve 103, pushing the connecting sleeve 103 and the guide sleeve 104 outward, realizing the rapid ejection of the guide sleeve 104. After the operator assembles the new guide sleeve 104 with the connecting sleeve 103, it is inserted along the inner side of the connecting end 9. The insertion of the connecting sleeve 103 will push the circular push plate 112 to move backward, compressing the reset spring 111 until the groove 105 of the connecting sleeve 103 is aligned with the slot 101. At this time, the compression spring 106 relaxes from the compressed state, pushing the locking post 107 to move outward. One end of the locking post 107 is re-embedded in the slot 101 and the groove 105, thereby locking the connecting sleeve 103.
