Description

Technical Field

[0001] This utility model relates to the field of wheel processing technology, and in particular to a cutting iron cleaning device for wheel processing. Background Technology

[0002] Currently, during the machining of railway wheels, when the tool holder slide is in operation, a certain amount of metal chips are generated between the cutting tool and the wheelset. When these chips fall off the tool, they accumulate at the tool tip, posing a safety hazard during machining. This accumulation of chips can scratch the already turned tread surface. If this continues for a long time, it will also increase the load on the tool holder slide, shorten the service life of the lathe, and affect the normal turning and maintenance of the rolling stock.

[0003] Therefore, there is an urgent need for a device for cleaning up cutting iron in wheel machining. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for cleaning up cutting iron in wheel processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting iron cleaning device for wheel processing includes a tool holder. The upper part of the tool holder has a pair of mounting slots. A flap is rotatably mounted inside one side of the slot. One end of the flap is equipped with an air jet block. The air jet block is supplied with air by an air cylinder set inside the mounting slot. The air cylinder is equipped with a piston rod inside. One end of the piston rod is connected to the bottom side of the flap through a push block. An air pipe is provided on the side of the cylinder wall away from the piston rod. The air pipe is connected to the air jet block.

[0007] Furthermore, in a preferred configuration, the tool holder is mounted on the slide saddle via a slide block.

[0008] Furthermore, a preferred configuration is that the flap fits snugly within the mounting groove in its natural state.

[0009] In addition, a preferred structure is that an air inlet is installed on the outer side of the knife holder, the air inlet is connected to the air inlet of the air cylinder, and the air cylinder is installed on the inner bottom side of the mounting groove.

[0010] In addition, a preferred structure is that the air cylinder has an air chamber inside, and a piston rod is slidably installed in the air chamber. One end of the piston rod extends out of the air cylinder and is connected to the push block. A limit plate is provided on the upper part of the push block. A rectangular slot is provided in the middle of the limit plate. A limit pin is slidably installed in the slot through a finger-shaped rocker arm. The other end of the finger-shaped rocker arm is connected to the bottom side of the flip plate.

[0011] In addition, a preferred structure is that an air pipe is installed on one side of the outer wall of the air cylinder, the air pipe is connected to the inside of the air cylinder, and the other end of the air pipe is connected to the jet block.

[0012] Furthermore, in a preferred configuration, a spring is connected between the piston rod and the inner wall of the cylinder.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, an external air source mechanism supplies air to the air cylinder. The air cylinder drives the flap to rotate via a pusher block, and in the process, the air is delivered to the air jet block. The air jet block sprays air synchronously as the flap rotates, which can not only remove long iron filings that fall on the cutter head, but also blow away small fragments, reducing the accumulation of iron filings on the cutter head and avoiding unnecessary serious losses and safety hazards.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A wheel machining cutting iron cleaning device includes a tool holder 3. The upper part of the tool holder 3 is provided with a pair of mounting slots 6. A flap 5 is rotatably installed inside one side of the slot. One end of the flap 5 is provided with an air jet block 51. The air jet block 51 is supplied with air by an air cylinder 7 provided inside the mounting slot 6. The air cylinder 7 is provided with a piston rod 8. One end of the piston rod 8 is connected to the bottom side of the flap 5 through a push block 9. An air pipe 52 is provided on the side of the cylinder wall away from the piston rod 8. The air pipe 52 is connected to the air jet block 51.

[0023] Furthermore, the tool holder 3 is mounted on the slide saddle 1 via the slide block 2.

[0024] Furthermore, the flap 5 is naturally fitted into the mounting slot 6.

[0025] Furthermore, an air inlet 4 is installed on the outer side of the knife holder 3. The air inlet 4 is connected to the air inlet end of the air cylinder 7, and the air cylinder 7 is installed on the inner bottom side of the mounting groove 6.

[0026] Furthermore, an air chamber is provided inside the air cylinder 7, and a piston rod 8 is slidably installed in the air chamber. One end of the piston rod 8 extends out of the air cylinder 7 and is connected to the push block 9. A limit plate 11 is provided on the upper part of the push block 9. A rectangular slot is provided in the middle of the limit plate 11. A limit pin 101 is slidably installed in the slot through a finger-shaped rocker arm 10, and the other end of the finger-shaped rocker arm 10 is connected to the bottom side of the flip plate 5.

[0027] Furthermore, an air pipe 52 is connected to one side of the outer wall of the air cylinder 7. The air pipe 52 is connected to the inside of the air cylinder 7, and the other end of the air pipe 52 is connected to the jet block 51.

[0028] Furthermore, a spring 12 is connected between the piston rod 8 and the inner wall of the air cylinder 7, and the piston rod 8 is automatically reset through the spring 12.

[0029] In this embodiment, the external air source mechanism is connected to the air inlet 4 provided on the tool holder 3. The gas is delivered into the air cylinder 7 and moves the piston rod 8. The piston rod 8 moves and the push block 9 moves synchronously. When the push block 9 moves, it guides and deflects the finger rocker arm 10 through the rectangular slot opened in the limiting plate 11. Then the flip plate 5 is pushed and flipped, and the iron filings that fall off during processing are removed.

[0030] Synchronously, when the piston rod 8 travels to half of the working stroke in the air cylinder 7, the piston part in the piston rod 8 passes the air inlet of the air pipe 52. At this time, while the piston rod 8 is being pushed synchronously, part of the gas is delivered to the air pipe 52 and ejected by the jet block 51 to blow off the waste.

[0031] In actual use, gas is input by an external gas source mechanism, and the piston rod 8 is pushed forward by the gas. Conversely, the spring 12 returns the piston rod 8 to its original position. This mechanism is the same as that of a single-acting cylinder, and will not be elaborated on here.

[0032] Of particular note is the special shape of the finger-shaped rocker arm 10, which causes the finger-shaped rocker arm 10 to deflect under the pushing and guiding action of the push block 9, thereby causing the flap 5 to deflect around the axis.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
