Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically to an arc guide rail with a buffer function. Background Technology

[0002] As the name suggests, a circular arc guide rail is a guide rail system with a circular arc shape. It guides and supports moving parts through a circular arc trajectory to achieve precise positioning and motion control. Its working principle is mainly based on the principles of rolling friction and sliding friction. In a circular arc guide rail, there is rolling friction between the slider and the track, while there is sliding friction between the balls or rollers inside the slider and the slider.

[0003] Most current circular arc tracks do not have a buffer function. Since some mobile platforms still have a high speed when entering the circular arc guide rail, the object will generate a large impact and vibration after directly entering the circular arc guide rail. This impact will not only cause potential damage to the object itself, but may also damage the guide rail system and other related components, thus reducing the service life of the circular arc guide rail. Utility Model Content

[0004] The purpose of this invention is to provide a circular arc guide rail with a buffer function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an arc guide rail with a buffer function, comprising a fixed platform, an arc guide rail fixedly connected to the top of the fixed platform, and multiple buffer seats fixedly connected to the top of the fixed platform near the inlet position. A buffer platform is slidably connected inside the buffer seat, and three return springs are fixedly connected to the bottom surface inside the buffer seat. The two ends of the three return springs are respectively fixedly connected to the bottom end of the buffer platform and the bottom surface inside the buffer seat.

[0006] As a further preferred embodiment of this technical solution, an adjustment rail is fixedly connected to the bottom of the fixed platform, and multiple fixed seats are slidably connected to the outer surface of the adjustment rail. An adjustment groove is opened on the bottom surface of the fixed seat, and a shaped disk is rotatably connected inside the adjustment groove. The outer surface of the shaped disk abuts against the bottom of the adjustment rail.

[0007] As a further preferred embodiment of this technical solution, one end of the irregularly shaped disk is fixedly connected to a polygonal adjusting column through one side wall of the adjusting groove, an adjusting ring is slidably connected to the outer surface of the polygonal adjusting column, a fixing sleeve is inserted into one end of the adjusting ring, and one end of the fixing sleeve is fixedly connected to one side of the fixing seat.

[0008] As a further preferred embodiment of this technical solution, a connecting column is fixedly connected to the bottom end of the fixed base, and a fixed base is slidably connected to the outer surface of the connecting column.

[0009] As a further preferred embodiment of this technical solution, the outer surface of the fixed base is provided with a threaded through hole, and a fixing bolt is threadedly connected inside the threaded through hole. The outer surface of the connecting column is provided with multiple slots, and one end of the fixing bolt is inserted into any one of the slots.

[0010] As a further preferred embodiment of this technical solution, a positioning post is slidably connected inside the buffer seat and at the positions of the three reset springs, and the top end of the positioning post is fixedly connected to the bottom end of the buffer platform.

[0011] As a further preferred embodiment of this technical solution, the bottom end of the positioning column is fixedly connected to a limiting cap through the bottom end of the fixing platform, and the top end of the buffer platform is fixedly connected to a rubber pad.

[0012] This utility model provides a circular arc guide rail with a buffer function, which has the following beneficial effects:

[0013] (1) When the mobile platform passes through the buffer platform, the buffer platform is pushed into the buffer seat by the mobile platform. During the entry process, the buffer platform provides flexible blocking to achieve initial buffering. After the buffer platform enters the buffer seat, the reaction force generated by the elastic deformation of the return spring pushes the buffer platform to fit tightly with the bottom of the mobile platform. Secondary buffering is achieved through the friction force generated by the rubber pad and the mobile platform. After the mobile platform passes through multiple buffer platforms, its speed is greatly reduced when it enters the arc guide rail, which greatly reduces the impact force on the arc guide rail and improves its service life.

[0014] (2) This utility model moves the fixed seat on the adjustment rail to a fixed position, then pulls the adjustment ring out of the fixed sleeve, rotates the polygonal adjustment column to drive the irregular disk to rotate, so that the surface of the irregular disk is tightly pressed against the bottom of the adjustment rail, thereby achieving rapid fixation of the fixed seat, making the fixed position of the arc track more flexible and improving the installation efficiency.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1-3 As shown in this embodiment, an arc-shaped guide rail with a buffer function includes a fixed platform 1, an arc-shaped guide rail 2 fixedly connected to the top of the fixed platform 1, and multiple buffer seats 3 fixedly connected to the top of the fixed platform 1 near the inlet position. A buffer platform 4 is slidably connected inside the buffer seat 3, and three return springs 6 are fixedly connected to the bottom surface inside the buffer seat 3. The two ends of the three return springs 6 are respectively fixedly connected to the bottom surface inside the buffer seat 3 at the bottom of the buffer platform 4. By setting the return springs 6, the pressure generated when the buffer platform 4 retracts can be converted into thrust, making the buffer platform 4 fit more tightly with the moving platform, increasing the friction between the two, and improving the buffering effect of the buffer platform 4 on the moving platform. By setting the buffer seats 3, the buffer platform 4 can be positioned. By setting the buffer seats 4, the moving platform can be flexibly blocked, so that the moving platform decelerates before entering the arc-shaped guide rail 2, thus achieving a buffering effect.

[0022] like Figure 1 and Figure 4 As shown, an adjusting rail 9 is fixedly connected to the bottom of the fixed platform 1. Multiple fixed seats 10 are slidably connected to the outer surface of the adjusting rail 9. An adjusting groove 11 is opened on the bottom surface of the fixed seat 10. A shaped disk 12 is rotatably connected inside the adjusting groove 11. The outer surface of the shaped disk 12 abuts against the bottom of the adjusting rail 9. The adjusting rail 9 can guide and limit the fixed seat 10. The shaped disk 12 can fix the fixed seat 10 by the compression between the shaped disk 12 and the adjusting rail 9.

[0023] like Figure 4As shown, one end of the irregularly shaped disk 12 passes through the inner side wall of the adjustment groove 11 and is fixedly connected to a polygonal adjustment column 13. An adjustment ring 14 is slidably connected to the outer surface of the polygonal adjustment column 13. A fixing sleeve 15 is inserted into one end of the adjustment ring 14. One end of the fixing sleeve 15 is fixedly connected to one side of the fixing seat 10. By setting the polygonal adjustment column 13, the irregularly shaped disk 12 can be rotated. By setting the adjustment ring 14, the polygonal adjustment column 13 can be fixed by cooperating with the fixing sleeve 15, so that the fixing seat 10 is fixed more stably.

[0024] like Figure 4 As shown, a connecting column 16 is fixedly connected to the bottom of the fixed base 10, and a fixed base 17 is slidably connected to the outer surface of the connecting column 16, which can adjust the height to adapt to different installation environments.

[0025] like Figure 4 As shown, a threaded through hole 18 is provided on the outer surface of the fixed base 17, and a fixing bolt 19 is threadedly connected inside the threaded through hole 18. Multiple slots 20 are provided on the outer surface of the connecting column 16. One end of the fixing bolt 19 is inserted into any one of the slots 20. By setting the slots 20, a fixing effect can be achieved by cooperating with the fixing bolt 19.

[0026] like Figure 3 As shown, a positioning post 7 is slidably connected inside the buffer seat 3 and at the position of the three return springs 6. The top of the positioning post 7 is fixedly connected to the bottom of the buffer platform 4. By setting the positioning post 7, the buffer platform 4 can be positioned to prevent it from tilting during the squeezing process.

[0027] like Figure 2 and Figure 3 As shown, the bottom end of the positioning column 7 passes through the bottom end of the fixed platform 1 and is fixedly connected to a limiting cap 8. The top end of the buffer platform 4 is fixedly connected to a rubber pad 5. The limiting cap 8 can limit the buffer platform 4 and prevent it from falling off. The rubber pad 5 can increase the friction between the buffer platform 4 and the moving platform, thereby improving the buffering effect.

[0028] This utility model provides a circular arc guide rail with a buffer function, and its specific working principle is as follows:

[0029] During the installation of the arc guide rail 2, the fixed seat 10 is moved on the adjusting rail 9 to a fixed position. Then, the adjusting ring 14 is pulled out from the fixed sleeve 15, and the polygonal adjusting column 13 is rotated to drive the irregular disk 12 to rotate, so that the surface of the irregular disk 12 is tightly pressed against the bottom of the adjusting rail 9, and the fixed seat 10 is quickly fixed. Then, the adjusting ring 14 is inserted back into the fixed sleeve 15 to complete the adjustment and subsequent fixation. When the moving platform passes the buffer platform 4, the buffer platform 4 is pushed into the buffer seat 3 by the moving platform. During the entry process, the buffer platform 4 provides flexible blocking to achieve initial buffering. After the buffer platform 4 enters the buffer seat 3, the reaction force generated by the elastic deformation of the return spring 6 pushes the buffer platform 4 to fit tightly against the bottom of the moving platform. Secondary buffering is achieved by the friction generated between the rubber pad 5 and the moving platform. After the moving platform passes through multiple buffer platforms 4, its speed is greatly reduced when it enters the arc guide rail 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
