Technical Field

[0001] The utility model relates to the field of planing tools, in particular to a precision planing tool for elevator solid guide rails. Background Art

[0002] The car elevator realizes stable vertical lifting by sliding up and down along the solid guide rail. When machining the solid guide rail, planing is required. The precision machining of the elevator solid guide rail usually requires special planing tools to ensure the dimensional accuracy, surface finish and running smoothness of the guide rail. Such planing tools are designed for machining the special profiles and materials of elevator guide rails.

[0003] Generally, the planer blades on the existing planing tools for solid guide rails are integral high-speed steel material planer blades with the cutter heads formed directly at the front ends of the tool bars. The planing surface of the planer blade is used to plane the surface of the guide rail. However, since the solid guide rail needs to be planed on multiple surfaces, and the existing planer blades use single-sided planing, the planing efficiency is slow.

[0004] Therefore, it is necessary to provide a new precision planing tool for elevator solid guide rails to solve the above technical problems. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a precision planing tool for elevator solid guide rails.

[0006] The precision planing tool for elevator solid guide rails provided by the utility model includes a top planing seat and two opposite side planing seats.

The driving plate and the two second supporting plates are respectively fixedly installed on the outer side wall of the side planing seat. The two first supporting plates are respectively fixedly installed on the outer side walls of the first connecting plate and the second connecting plate. The adjusting rod is rotatably connected to the first supporting plate and the second supporting plate respectively, and the adjusting rod is threadedly connected to the driving plate. One end of the second guiding rod is fixedly connected to the first supporting plate, and the other end of the second guiding rod is slidably connected to the second supporting plate.

[0009] Further, two opposite dovetail grooves are formed in the bottom of the top planing seat, and the tops of the two first connecting plates and the two second connecting plates are respectively slidably installed in the two dovetail grooves.

[0021] In the specific implementation process, as Figures 1 - 4 shown, the precision machining planer for elevator solid guide rails includes a top planing seat 1 and two opposite side planing seats 2. Planing tools 3 are provided at the centers of the top planing seat 1 and the two side planing seats 2. The three sides of the elevator solid guide rail are simultaneously planed by the three planing tools 3. Two first connecting plates 4 and two second connecting plates 5 are respectively provided at the tops of the two side planing seats 2. A first driving mechanism is provided on one side of the top planing seat 1. The first driving mechanism is used to drive the two first connecting plates 4 and the two second connecting plates 5 to move towards or away from each other. A second driving mechanism for driving the two side planing seats 2 to slide along their surfaces is further provided on the outer sides of the two first connecting plates 4;

[0022] Two opposite dovetail grooves 15 are opened at the bottom of the top planing seat 1. The tops of the two first connecting plates 4 and the two second connecting plates 5 are respectively slidably installed in the two dovetail grooves 15.

[0023] The first driving mechanism includes a bidirectional threaded rod 6 and a first guiding rod 7. A first supporting plate 8 is rotatably mounted on the outer surface of the bidirectional threaded rod 6. The two ends of the bidirectional threaded rod 6 are respectively threadedly connected to two first connecting plates 4. A second supporting plate 9 is fixedly connected to the outer surface of the first guiding rod 7. The outer surface of the first guiding rod 7 is respectively slidably connected to two second connecting plates 5. The first supporting plate 8 and the second supporting plate 9 are respectively fixedly mounted on one side of the top planing seat 1;

[0024] It should be noted that the two ends of the bidirectional threaded rod 6 are respectively left-handed and right-handed threads. The two ends of the bidirectional threaded rod 6 are respectively threadedly connected to two first connecting plates 4. When the bidirectional threaded rod 6 rotates, it drives the two first connecting plates 4 to move towards or away from each other along the direction of the dovetail groove 15.

[0025] The second driving mechanism includes a driving plate 10, an adjusting rod 11, a second guiding rod 12, two opposite first supporting plates 13 and two opposite second supporting plates 14. The driving plate 10 and the two second supporting plates 14 are respectively fixedly mounted on the outer side wall of the side planing seat 2. The two first supporting plates 13 are respectively fixedly mounted on the outer side walls of the first connecting plate 4 and the second connecting plate 5. The adjusting rod 11 is respectively rotatably connected to the first supporting plate 13 and the second supporting plate 14. The adjusting rod 11 is threadedly connected to the driving plate 10. One end of the second guiding rod 12 is fixedly connected to the first supporting plate 13, and the other end of the second guiding rod 12 is slidably connected to the second supporting plate 14;

[0026] By turning the adjusting rod 11 to drive the driving plate 10 to move, and then the driving plate 10 drives the side planing seat 2 to move along the direction of the first connecting plate 4 and the second connecting plate 5, so as to adjust the height of the two side planing seats 2.

[0027] On the inner side walls of the two side planing seats 2, there is also a telescopic support member. The telescopic support member includes a fixed seat 16 fixedly mounted on the inner side wall of the side planing seat 2 and a movable rod 17. One end of the movable rod 17 is slidably mounted inside the fixed seat 16. An elastic member 18 is also provided inside the fixed seat 16. The elastic member 18 is in contact with one end of the movable rod 17. A universal ball 19 is embedded at the other end of the movable rod 17. When the universal ball 19 is in contact with the surface of the side planing seat 2, the elastic member 18 contracts, and the universal ball 19 moves in line contact with the side planing seat 2, avoiding large surface contact friction and affecting the sliding effect;

[0028] In a specific embodiment, the elastic member 18 is preferably a compression spring, and the elastic force of the compression spring drives the movable rod 17 to expand and contract.

[0029] The working principle provided by the present utility model is as follows: When the planing tool is in use, the two ends of the bidirectional threaded rod 6 are respectively left-handed threads and right-handed threads. The two ends of the bidirectional threaded rod 6 are respectively threadedly connected to the two first connecting plates 4. When the bidirectional threaded rod 6 rotates, it drives the two first connecting plates 4 to move towards or away from each other along the direction of the dovetail groove 15. The two first connecting plates 4 and the two second connecting plates 5 drive the two side planing seats 2 to move, for adjusting the distance between the two side planing seats 2. The driving mechanism II drives the two side planing seats 2 to slide along the surfaces of the two first connecting plates 4, for adjusting the height of the two side planing seats 2 and the top planing seat 1. The present utility model can perform planing on three sides simultaneously, improving the planing efficiency. Each planing tool can also move and adjust its position in the direction of approaching or departing from the end face to adapt to the processing of solid guide rails of different sizes. When the universal ball 19 is in contact with the surface of the side planing seat 2, the elastic member 18 contracts, and the movement of the universal ball 19 and the side planing seat 2 is in line contact, avoiding the large frictional force in surface contact and affecting the sliding effect.
