Description
Technical Field
[0001] The utility model relates to the technical field of small-sized railway track maintenance equipment, in particular to a weld overflow flash grinding machine. Background Art
[0002] With the development of seamless railways, thermite welding joints of rails have replaced the original ordinary joints, and the quality of thermite welding seams has become the key to the safety of seamless railways. During the welding process, when the sand mold is not sealed tightly or the weld is not straight, the molten steel overflows from the gap between the sand mold and the rail during casting, forming overflow flash connected to the parent material on the rail surface at the edge of the weld. The root of the overflow flash is prone to casting defects, and interferes with the flaw detection wave, which is easy to cause stress concentration and damage leakage, and easily cause rail breakage, affecting driving safety.
[0003] At present, the commonly used methods for dealing with weld overflow flash are: hand hammer and flat shovel, handheld grinder and angle grinder. The grinding standard is: the parent material must not be damaged when grinding the overflow flash, the grinding surface contour should be smooth, without pits, no obvious micro-cracks, peeling, sharp tool cuts and other traces, and the grinding edges must be eliminated after grinding to prevent stress concentration. When grinding after welding is completed, use a flat shovel and a small hammer to remove the root connection of the overflow flash. After removal, use an angle grinder or a rod grinder to grind the burrs on the rail waist and weld ribs. Due to the complex contour of the rail itself, these tools will not be able to be accurately positioned during operation, which may cause damage to the parent material or unclean grinding of the flash during the grinding process.

[0071] In an alternative embodiment of the present example, the first connecting arm 402 is provided with a sleeve portion that cooperates with the connecting shaft 413.

[0076] See Figure 1 As shown, in an alternative embodiment of the present example, the clamping device 400 and the grinding head 303 are located on both sides of the gearbox 309. Further, the connecting shaft 413 and the grinding head 303 are located on both sides of the gearbox 309.
[0077] See Figures 1-5 As shown, in an alternative embodiment of the present example, the driving device 100 and the clamping device 400 are located on both sides of the gearbox 309; the grinding head 303 and the driving device 100 are located on the same side of the gearbox 309; to balance the weld overflow flash grinding machine.

[0079] Specifically, see Figures 1-3As shown in the figure, in an alternative solution of this embodiment, the number of the limiting members 306 is multiple; one of the limiting members 306 is located between the grinding head 303 and the housing of the gearbox 309.

[0084] In an alternative solution of this embodiment, a driving handle 200 is connected to the driving device 100. The driving handle 200 can be installed above or below the relative position of the driving device 100 by threaded connection according to actual needs.
[0085] Due to the relatively complex contour of the rail itself, there is no effective tool in the prior art that can achieve full-section grinding of the rail, including the tread, gauge corner, head side, jaw, web, triangular area, and bottom surface, etc. Moreover, accurate positioning cannot be achieved during the operation process, which may cause damage to the base material or incomplete grinding of the burrs during the grinding process. The weld overflow burr grinding machine described in this embodiment can quickly and accurately locate the grinding position, and can achieve grinding of the rail, including the tread, gauge corner, head side, jaw, web, triangular area, and bottom surface, without damaging the base material, with a reasonable structural design, simple operation, and easy to carry.
[0086] To understand this embodiment more clearly, the following briefly describes the operation steps of the weld overflow flash grinding machine according to this embodiment:
[0087] 1. According to the actual operation requirements, select whether to install the drive handle 200. If it is necessary to install the drive handle 200, install it at the relative upper or lower position of the drive device 100 according to the requirements.
[0088] 2. Remove the locking bolt 301 and the grinding head cover 302, install the first flat key 304 onto the keyway of the output shaft of the gearbox 309, then align the keyway on the grinding head 303 with the first flat key 304, and insert it onto the output shaft so that one end face of the grinding head 303 fits against the step of the output shaft. Install the locking bolt 301 and the grinding head cover 302 back to their original positions and lock them.
[0089] 3. Place the clamping device 400 on the rail 500 so that the rail tread fits against the clamping base 411. Open the measuring scale 403, adjust the position of the clamping base 411 on the rail 500 according to the part to be ground, and after adjustment, tighten the locking handle 410 to fix the clamping base 411 on the rail 500. Close the measuring scale 403 after adjustment. Specifically, after the measuring scale 403 is rotated and opened, since the end face of the measuring scale 403 coincides with the end face of the grinding head 303, make the end face of the measuring scale 403 abut against the grinding position for quick and accurate positioning. Then adjust the clamping device 400, and after it reaches the appropriate position, rotate the locking handle 410 to fix the clamping device 400 on the rail 500.
[0090] 4. After aligning the connecting shaft 413 of the clamping device 400 with the connecting block 311 of the grinding device 300, rotate the rotating handle 415 on the clamping device 400 so that the connecting shaft 413 is installed onto the connecting block 311 by means of the threaded structure.
[0091] 5. Turn on the switch of the drive device 100 and grind along the contour of the rail 500. During the operation, hold the drive device 100 with both hands or hold the drive device 100 with one hand and the drive handle 200 with the other hand. During the grinding process, when the grinding device 300 makes a circular motion relative to the rail end face, make the two limit pieces 306 fit against the rail 500 so that the limit pieces 306 and the grinding head 303 will not damage the base material during the grinding process. After grinding to a certain position, rotate the weld overflow flash grinding machine, and according to the above method, grind the weld overflow flash on the opposite side of the rail. Compared with similar products, the weld overflow flash grinding machine according to this embodiment can effectively grind the entire cross-section of the rail tread, gauge corner, rail head side, jaw, rail web, triangular area, and bottom surface.

[0093] 7. Release the driving handle 200 and remove the clamping device 400.
[0094] 8. The grinding is completed.
[0095] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
