Abstract
Description
Technical Field
[0001] The utility model relates to the technology of rail processing, in particular to a complete set of automatic clamping and grinding equipment for the root end of the forging section of a rail. Background Art
[0002] At present, rail production companies manually load, clamp, adjust and position rails. The bottom forming section of the forked rail forging section is milled by a milling head on a milling machine. Then the rail is unclamped and removed from the machine tool bed and moved to another area where the flash on the transition section is ground manually, and the wheels are chamfered and deburred manually around the processed surface. This results in low production efficiency, a large number of workers, a poor environment and is not friendly to human health. Summary of the Utility Model
[0003] The utility model provides a complete set of automatic clamping and grinding equipment for the root end of the forging section of a rail, aiming to solve the above problems.
[0004] The technical solution of the utility model is as follows:
[0005] A complete set of automatic clamping and grinding equipment for the root end of the forging section of a rail, the complete set of equipment includes a gantry milling machine, and the complete set of equipment further includes a clamping, flash grinding / burring device. The clamping is installed on the workbench of the gantry milling machine, and the flash grinding / burring device is installed on the side or above the machine tool bed of the gantry milling machine, behind the milling mechanism of the gantry milling machine; a rail, the root end of its forging section is fixed on the clamping and moves with the workbench of the gantry milling machine together with the clamping. The root end of the forging section of the rail sequentially passes through the milling mechanism and the flash grinding / burring device of the gantry milling machine, and is milled by the milling mechanism of the gantry milling machine and ground / burred by the flash grinding / burring device.
[0006] Further refining the above technical solution, the complete set of equipment further includes an auxiliary automatic roller table frame, and the auxiliary automatic roller table frame is installed in front of the gantry milling machine; the rail is supported on the auxiliary automatic roller table frame; this makes the movement of the rail stable and avoids the rail from being bent.
[0007] Further refining the above technical solution, the clamping device includes three jacking mechanisms and a clamping main body. The three jacking mechanisms are distributively installed on the workbench of the gantry milling machine, and the clamping main body is supported and fixed on the three jacking mechanisms. A cavity is provided thereon. The three jacking mechanisms are Jacking Mechanism I, Jacking Mechanism II, and Jacking Mechanism III. Jacking Mechanism I and Jacking Mechanism II are located at the front points of the clamping main body and are separated on both sides, and Jacking Mechanism III is located at the rear point of the clamping main body and is centered. The clamping main body is of the side-clamping fixed type; the root end of the rail forging section is placed in the upper cavity of the clamping main body and is fixed by side-clamping of the clamping main body. The fixation is carried out in two steps. First, pre-press and fix. The operator operates according to the existing milling requirements of the rail forging section, using the "I"-shaped calibration tool and the scribing height scale. During the calibration process, if it is found that the placement position of the rail is skewed, it is adjusted through the three jacking mechanisms. After all the rails are adjusted to meet the milling requirements, the rails are locked and fixed again.
[0008] Further refining the above technical solution, the flash grinding / burr removing device includes a grinding mechanism and a deburring mechanism. The grinding mechanism and the deburring mechanism share a gantry. The gantry is mounted on the bed of the gantry milling machine. The grinding mechanism and the deburring mechanism are both floating types; the overall layout is reasonable. The floating grinding mechanism and deburring mechanism enable the tool head to float and press-fit against the end face of the rail forging section during grinding and deburring, resulting in better grinding and deburring effects.
[0009] Further refining the above technical solution, there are n clamping devices in total. The n clamping devices are arranged side by side and are Clamping Device X; synchronous processing of the root ends of multiple rail forging sections can be achieved simultaneously.
[0010] Further refining the above technical solution, there are n milling mechanisms in total for the gantry milling machine, which are Milling Mechanism X. The Milling Mechanism X are arranged side by side. There are n flash grinding / burr removing devices in total. The n flash grinding / burr removing devices are arranged side by side and are Flash Grinding / Burr Removing Device X. The Clamping Device X, the Milling Mechanism X, and the Flash Grinding / Burr Removing Device X are in a line; the root end of the rail forging section fixed on the Clamping Device X moves with the workbench of the gantry milling machine and passes through the Milling Mechanism X and the Flash Grinding / Burr Removing Device X in sequence. The Milling Mechanism X mills it, and the Flash Grinding / Burr Removing Device X grinds / removes burrs.
