Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a chip removal device used in machine tools. Background Art

[0002] Machine tools are machines used to manufacture machines and machinery.

[0003] There are fixtures inside the machine tool for fixing the workpiece. The most common fixture is the chuck. The workpiece is fixed by the fixture, and then the workpiece can be processed according to the requirements of the workpiece. For example, during high-temperature processing such as welding and cutting, smoke and dust will be generated inside the machine tool, and dust extraction equipment is needed to remove the smoke and dust inside the machine tool in time.

[0004] The common dust extraction equipment now is to connect the exhaust fan with the inside of the machine tool through a connecting pipe. When the exhaust fan is working, negative pressure is generated inside the connecting pipe, so that the smoke generated inside the machine tool can be discharged through the connecting pipe. However, the high-temperature smoke generated by welding and cutting will contain some solid debris. The method of directly extracting it through the exhaust fan will cause the solid debris to directly contact the impeller inside the exhaust fan, causing the exhaust fan to be damaged, thereby causing the dust extraction mechanism to fail to work normally. For this reason, we propose a chip removal device for machine tools. Utility Model Content

[0005] The utility model aims to provide a chip removal device for a machine tool to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-3 The chip removal device shown is used for a machine tool, comprising a machine tool body 101 and a dust extraction mechanism. The dust extraction mechanism extracts the smoke and dust generated by the operation inside the machine tool body 101, and collects the solid debris inside the smoke and dust.

[0023] In a preferred embodiment, a dust extraction mechanism is arranged outside the machine tool body 101, and the dust extraction mechanism is used to discharge the smoke generated by the internal operation of the machine tool body 101. The dust extraction mechanism includes an exhaust fan 201 installed on one side of the machine tool body 101, and a connecting pipe 202 is arranged at one end of the exhaust fan 201, and one end of the connecting pipe 202 is fixedly connected with the top of the machine tool body 101. An opening 203 is opened on the outer wall of the connecting pipe 202, and a filtering mechanism is arranged inside the opening 203. The operation of the exhaust fan 201 generates a negative pressure inside the connecting pipe 202. Since the connecting pipe 202 is connected to the inside of the machine tool body 101, the smoke generated inside the machine tool body 101 can be sucked into the connecting pipe 202, and then the solid debris in the smoke is filtered through the cooperation of the filtering mechanism inside the connecting pipe 202, thereby completing the collection of the solid debris, so that the solid debris will not contact the exhaust fan 201, thereby ensuring the stable operation of the dust extraction mechanism.

[0024] Among them, the filtering mechanism includes an insert ring 301, which is inserted and arranged inside the opening 203. The middle part of the inner wall of the insert ring 301 is fixedly connected with a filter screen 302. The gas part in the smoke can directly pass through the filter holes on the filter screen 302, but the solid debris cannot pass through the filter holes on the filter screen 302. That is, when the smoke passes through the insert ring 301, the solid debris therein can be left on the top of the filter screen 302. Through the setting of the opening 203, the filtering mechanism and the connecting pipe 202 are separately set, which is convenient for removing the insert ring 301 from the opening 203 and removing the debris collected on the filter screen 302.

[0025] Among them, rubber rings 303 are attached to the top and bottom ends of the plug ring 301, and the rubber ring 303 and the opening 203 are set with interference fit. Through the setting of the rubber ring 303, the plug ring 301 is inserted more tightly into the opening 203, and there will be no air leakage between the plug ring 301 and the connecting pipe 202, thereby improving the stability of the dust extraction mechanism.

[0026] The outer wall of the machine tool body 101 is symmetrically fixedly connected with connecting strips 402, one side of the two connecting strips 402 is fixedly connected with a fixing strip 401, one side of the fixing strip 401 is provided with a slide groove 403, the inner wall of the slide groove 403 is slidably connected with a slider 404, a connecting mechanism is provided between the slider 404 and the insert ring 301, the connecting mechanism includes a rotating hole 501 provided on one side of the slider 404, the inner wall of the rotating hole 501 is rotatably connected with a rotating rod 502, one end of the rotating rod 502 is fixedly connected with the outer wall of the insert ring 301, the other end of the rotating rod 502 is fixedly connected with a handle 503, which slides in the slide groove 403 through the slider 404, and With the connection of the rotating rod 502, the plug ring 301 can move synchronously with the slider 404. That is, when it is necessary to take out the debris collected in the plug ring 301, you only need to hold the handle 503 to move the rotating rod 502, so that the slider 404 and the plug ring 301 can move together, until the plug ring 301 is completely separated from the opening 203. At this time, rotating the rotating rod 502 can rotate the plug ring 301 until the plug ring 301 rotates 180 degrees. At this time, the debris in the plug ring 301 is poured out, and a collection frame is hung on one side of the machine tool body 101, and the poured debris falls directly into the collection frame, further improving the convenience of debris collection.

[0027] Among them, the bottom end of the slider 404 is fixedly connected to the limiting block 602, and the bottom end of the inner wall of the slide groove 403 is provided with a limiting groove 601, and the outer wall of the limiting block 602 is slidably connected to the inner wall of the limiting groove 601. The limiting block 602 and the limiting groove 601 limit each other, so that the slider 404 can slide stably in the slide groove 403, and the slider 404 will not be separated from the slide groove 403, so that when the slider 404 is against the inner wall of the slide groove 403, the plug ring 301 is just inserted into the opening 203, which ensures the stability of the operation of the filtering mechanism.

[0028] Among them, a threaded hole 701 is opened at the top of the fixing strip 401, and the interior of the threaded hole 701 is connected to the interior of the slide groove 403. The inner wall of the threaded hole 701 is connected to the locking bolt 702. When the slider 404 moves to abut against the inner wall of the slide groove 403, the plug ring 301 is just stuck in the opening 203. Then, by screwing the locking bolt 702 in the threaded hole 701, the locking bolt 702 moves down and abuts against the top of the slider 404, the slider 404 can be positioned, thereby positioning the plug ring 301, so that the plug ring 301 will not move automatically, further improving the stability of the filter mechanism.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
