Embodiment 1
[0040] Such as figure 1 As shown, Embodiment 1 of the present invention provides a rail fine grinding machine, including a moving frame 1; a lifting mechanism, placed on the moving frame 1, which can move vertically relative to the moving frame 1; fine grinding The mechanism 3 is connected to the lifting mechanism in a swinging manner, and moves vertically with the lifting mechanism relative to the moving frame; the power mechanism 4 is connected to the fine grinding mechanism 3 in transmission.
[0041] The rail fine grinding machine described in the embodiment of the present invention, when applied, realizes the horizontal orientation adjustment of the fine grinding mechanism through the horizontal movement of the moving frame, and realizes the vertical orientation adjustment of the fine grinding mechanism through the up and down movement of the lifting mechanism. It can be seen that the above-mentioned rail fine grinding machine can realize the multi-point positioning of th...
Embodiment 2
[0052] Embodiment 2 of the present invention discloses a rail fine grinding machine. This embodiment adds a locking device on the basis of Embodiment 1. The locking device includes a limiting plate and a locking mechanism; One end is fixedly connected with the guide post 22, and a limiting groove is arranged on the limiting plate; the locking mechanism is connected with the limiting plate through the limiting groove, so as to limit the movement of the limiting plate.
[0053] Specifically, the limiting plate can be a semi-fan-shaped structure, and the two ends of the semi-fan-shaped limiting plate are respectively an A end and a B end, and the longer side of the A and B ends is fixed to the guide post 22 The middle part of the half-sector limiting plate is provided with the limiting slots extending to the A end and the B end.
[0054] Further, the locking mechanism includes a locking nut, a locking screw, and a locking wrench, the locking wrench is threadedly connected to one ...
Embodiment 3
[0057] Such as Figure 6A , 6B As shown, Embodiment 3 of the present invention discloses a rail refiner, which adds a rotating mechanism on the basis of Embodiment 1, and the rotating mechanism includes a rotating shaft 61, a rack 62, and a gear 63; the gear 63 is sleeved on the rotating shaft 61; one end of the rack 62 is fixedly connected with the guide post 22, and the other end is engaged with the gear 63; the rotating mechanism drives the guide post 22 around the pin shaft 221 rotate.
[0058] Specifically, a wheel 611 can be provided at the end of the rotating shaft 61, and the rotating shaft 61 can be driven to rotate by rotating the wheel 611, and then the guide post 22 can be driven around the pin shaft 221 through the rack 62. rotate. In addition, a telescopic dustproof cover 66 may be provided outside the rack 62 to protect the rack 62 .
[0059] In addition, a buffer spacer 67 may also be provided on the rack 62 to relieve vibration during movement. The rack 6...

Abstract
The embodiment of the invention discloses a steel rail refiner. The steel rail refiner comprises a movable framework, a lifting mechanism, a refining mechanism, and a power mechanism, wherein the lifting mechanism is arranged on the movable framework, and can move up and down in the vertical direction of the movable framework; the refining mechanism is in swing connection to the lifting mechanism,and can move up and down along with the lifting mechanism; and the power mechanism is connected to the refining mechanism for driving the refining mechanism to work. While the steel rail refiner provided by the embodiment of the invention is applied, the movable framework horizontally moves to realize direction regulation in the horizontal direction of the refining mechanism, and the lifting mechanism moves up and down to realize direction regulation in the vertical direction of the refining mechanism, and therefore, the steel rail refiner can realize multi-point positioning, on a steel rail,of the refining mechanism in a mode that the movable framework is matched with the lifting mechanism. The steel rail refiner is simple in structure, is convenient in operation and is low in cost. Moreover, the refining mechanism is in swing connection to the lifting mechanism, so that point contact between the refining mechanism and the steel rail is realized, the grinding effect is good, and efficiency is high.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a rail fine grindingmachine. Background technique [0002] With the leap-forward development of national railways, the speed of trains continues to increase, and the requirements for the appearance quality of seamless railways are also getting higher and higher. Especially the quality of the appearance quality of the seamless railway welded joint directly affects the service life of the seamless railway and the running speed of the train. Therefore, improving the appearance quality of welded joints is an urgent problem to be solved at this stage. [0003] There are mainly two types of existing grinding tools: (1) integrated equipment with a high degree of automation. This type of grinding tool has a complex structure, which is difficult for on-site grinding workers to use, and the cost is very high. (2) Multiple pieces of scattered tools are used in combination. Although thi...
