Description

Technical Field

[0001] This utility model relates to the field of guiding devices, specifically a guide shaft that is easy to position. Background Technology

[0002] In the field of mechanical transmission, the guide shaft is a key component that guides the precise movement of moving parts. The accuracy and convenience of its positioning directly affect the operating efficiency and reliability of the equipment.

[0003] Currently, traditional guide shafts often use fixed blocks or nuts to limit the stroke of moving parts. While fixed blocks provide reliable physical limits, their fixed position after installation makes it difficult to adapt to stroke adjustment requirements under different working conditions. Nut limits require repeated tightening and adjustment, which is cumbersome and has low precision. They also fail to meet the demands of modern industrial equipment for efficient, flexible, and reliable transmission. Utility Model Content

[0004] The purpose of this invention is to provide a guide shaft that is easy to position, so as to solve the problem of cumbersome positioning operation of the traditional positioning shaft limiting device mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide shaft for easy positioning, comprising a shaft body with a rack, and a limiting member assembled from a sliding sleeve and a pair of side plates. The limiting member is sleeved on the shaft body. A gear is rotatably installed inside the sliding sleeve, and the gear meshes with the rack. A pair of swing arms are rotatably installed on the side wall of the sliding sleeve. An elastic member connects the pair of swing arms so that the swing arms can rotate around the shaft through the elastic member until their ends abut against the gear and restrict the rotational displacement of the gear.

[0006] Preferably, the side wall of the shaft is provided with a groove for accommodating the rack, and the rack is fixedly installed in the groove by bolts.

[0007] Preferably, each of the sidewalls of the pair of swing arms is fixedly fitted with a pressure plate, and the elastic member is a spring sheet disposed between the pair of pressure plates, with the two torsion arms of the spring sheet respectively connected to the pressure plate.

[0008] Preferably, the sidewall of the sliding sleeve is provided with a groove for accommodating the side plate.

[0009] Preferably, friction rings are fixedly installed on the sidewalls of the gears, and the end of the swing arm extends to abut against the friction rings.

[0010] Preferably, the corners of the sliding sleeve and the side plate are rounded for a smooth transition.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a rack, a sliding sleeve, a gear, a swing arm, and an elastic component to form a limiting assembly on the shaft that can be quickly positioned. The limiting assembly can be quickly adjusted and fixed in position. Compared with the traditional limiting structure that requires repeated adjustments with tools, this application can complete the positioning with simple operation, which greatly shortens the equipment debugging and workstation switching time. Through the precise cooperation of each component, the travel of the moving parts on the shaft can be accurately limited, meeting the requirements of high-precision operation and thus improving production efficiency.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a guide shaft for easy positioning, including a shaft body 1 with a rack 2, the side wall of the shaft body 1 having a groove for accommodating the rack 2, the rack 2 being fixedly installed in the groove by bolts, wherein the rack 2 is an oblique rack, and a limiting member consisting of a sliding sleeve 3 and a pair of side plates 5, the side wall of the sliding sleeve 3 having a groove for accommodating the side plates 5, the corners of the sliding sleeve 3 and the side plates 5 being rounded for smooth transition, the advantage of this design is to avoid sharp corners scratching the skin, the limiting member being sleeved on the shaft body 1, and a gear 6 being rotatably installed inside the sliding sleeve 3, the gear 6 meshing with the rack 2. The corresponding gear 6 is a helical gear. A pair of swing arms 7 are rotatably mounted on the side wall of the sliding sleeve 3. Friction rings 9 are fixedly mounted on the side wall of the gear 6. The end of the swing arm 7 extends to abut against the friction ring 9, so that the gear 6 can be locked at any position by adjusting the pressure of the swing arm 7 on the friction ring 9. An elastic member is connected between the pair of swing arms 7 so that the swing arm 7 can rotate around the axis through the elastic member to abut against the gear 6 at the end and limit the rotational displacement of the gear 6. A pressure plate 4 is fixedly mounted on the side wall of each pair of swing arms 7. The elastic member is a spring plate 8 located between the pair of pressure plates 4. The two torsion arms of the spring plate 8 are respectively connected to the pressure plate 4.

[0020] When the position of the sliding sleeve 3 needs to be adjusted, by pressing and engaging a pair of pressure plates 4, the pressure plates 4 are forced to compress the spring plate 8 and drive the swing arm 7 to rotate around the axis away from the friction ring 9, thereby releasing the constraint on the gear 6. At this time, the position of the sliding sleeve 3 can be adjusted by sliding on the shaft 1. After adjusting to the specified position, the pressure plates 4 are released, the spring plate 8 releases its own elastic potential energy and drives the swing arm 7 to rotate to the end and contact the friction ring 9, thereby achieving rapid braking.

[0021] This application uses a rack 2, a sliding sleeve 3, a gear 6, a swing arm 7, and an elastic component to form a quick-positioning limiting assembly on the shaft 1. The limiting assembly can be quickly adjusted and fixed in position. Compared with the traditional limiting structure that requires repeated adjustments with tools, this application can complete the positioning with simple operation, which greatly shortens the equipment debugging and workstation switching time. Through the precise cooperation of each component, the stroke of the moving parts on the shaft 1 can be accurately limited, meeting the requirements of high-precision operation and thus improving production efficiency.
