Description

Technical Field

[0001] The utility model belongs to the field of rail production, and in particular relates to a rail sizing device. Background Art

[0002] At present, a certain rail processing line completes the rail sizing by installing a sizing baffle. After the sizing baffle of the sizing machine is extended and positioned, it is sent to the sawing and drilling combination machine tool for sawing to meet the conventional sizing production of 25 meters and 100 meters. Export rails require multiple sizing specifications, such as: 11m, 12m, 12.5m, 18m, 24m, 24.38mm, 25m, 50m, 75m, 100m, 24.96m, 24.92m, 24.84m, etc. The existing rail processing line cannot meet the sizing requirements of multiple specifications. There are two ways to use. One is to use manual measurement to locate the position, and then send it to the sawing and drilling combination machine tool for sawing by the swing roller and hoisting device. Due to the large error in manual measurement and marking, the measurement efficiency is low. The other is to move the sizing baffle and make adjustments. Changing the sizing work is difficult and time-consuming. The failure to meet the export rail requirements has caused serious constraints on the execution of product contracts. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model aims to provide a rail sizing device to meet the production requirements of rails of any sizing specifications.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A rail sizing device comprises a base, a gantry frame, a lifting hydraulic cylinder, a lifting bracket, a lifting roller, a reduction motor, a main bearing seat, an active roller, an active roller bearing seat, and a lifting roller bearing seat.

[0018] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0019] Example 1

[0020] See Figure 1 , Figure 2A rail sizing device is installed on both sides of the saw-drill combination machine tool, and is about 5m away from the saw-drill combination machine tool. It can be directly modified on the transport roller, and the rail sizing device is used to replace a set of transport rollers on both sides of the saw-drill combination machine tool. The rail sizing device includes a base 1, a gantry frame, a lifting hydraulic cylinder 7, a lifting bracket 6, a lifting roller 4, a reduction motor 9, a main bearing seat, an active roller 3, an active roller bearing seat 2, and a lifting roller bearing seat 5. The gantry frame is fixedly connected to the base 1 by fixing bolts, and both ends of the active roller 3 are installed on the active roller bearing seat 2. The bearing seat is connected to the base 1. The output shaft of the reduction motor 9 is connected to the active roller 3 through a coupling 8, and the coupling 8 can be supported by a bracket fixed on the base 1. The reduction motor 9 is fixedly connected to the base 1, and the reduction motor 9 is a servo reduction motor 9. A lifting roller 4 is provided directly above the active roller 3. The lifting roller 4 is installed on a lifting roller bearing seat 5. The lifting roller bearing seat 5 is fixed on a lifting bracket 6. A lifting hydraulic cylinder 7 is fixedly connected to a gantry bracket 10 by connecting bolts. The lifting bracket 6 is connected to a piston rod of the lifting hydraulic cylinder 7. The lifting bracket 6 is slidably connected to the gantry frame.

[0021] The rail sizing device further comprises a slideway 15 and a slider 12 . The slideway 15 is fixed on the gantry frame. The slideway 15 is slidably connected to the slider 12 . The slider 12 is fixedly connected to the lifting bracket 6 .

[0022] Example 2

[0023] See Figure 1-Figure 3 , which is different from Example 1, is that the rail sizing device further includes an adjustable baffle 11, a lead screw 13, a nut 14, and a bearing. The lead screw 13 is connected to the top of the gantry frame through the bearing, the lead screw 13 is threadedly connected to the nut 14, and the adjustable baffle 11 is fixedly connected to the nut 14. A slideway 15 is fixedly connected to the adjustable baffle 11, the slideway 15 is slidably connected to the slider 12, and the slider 12 is fixedly connected to the lifting bracket 6. The height of the adjustable baffle 11 is adjusted by rotating the lead screw 13, thereby adjusting the working position of the lifting bracket 6. There is no need to replace the gantry bracket 10, which reduces the workload of on-site debugging.

[0024] The 100-meter rail runs on the processing line transport roller until the fixed-length detection signal is triggered. When the fixed-length length of the rail minus the actual length of the rail = 1m, the transport roller stops running, and the automatic fixed-length device of the rail starts working. The actual length of the rail can be measured by the laser rangefinder. The lifting and lowering rollers are driven by the lifting hydraulic cylinder 7 to descend from the original position until the lifting roller 4 contacts and sticks to the rail head and stops descending. Then the active roller 3 starts to rotate under the drive of the servo reduction motor 9, driving the rail to continue running. When the actual length of the rail is equal to the fixed-length length of the rail, the active roller 3 stops rotating, and the lifting roller 4 is lifted to the original position. The fixed-length sawing of the rail is completed by the saw-drill combination machine tool, and the transport roller transports the fixed-length rail to the rail collection area.

[0025] The utility model adopts a lifting roller 4 that can be lifted and lowered to cooperate with the driving roller 3 to transport the rails, which can meet the sizing requirements of rails of different specifications and models. At the same time, when the lifting roller 4 is close to the rail head, the driving roller 3 and the rail can be prevented from slipping. The rail sizing device provided by the utility model can reduce the manual participation in sizing work, improve work efficiency, increase product yield, and meet the production needs of rails of any sizing specifications.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Through the above specific implementations, those skilled in the art can easily implement the utility model. However, it should be understood that the utility model is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
