Description

Technical Field

[0001] The utility model relates to the technical field of chip processing, in particular to a purging device for cutting waste of automobile parts. Background Technique

[0002] Cutting processing refers to a machining method that uses a tool with a regular shape to remove excess material from the surface of a workpiece, so as to ensure that the geometric shape, dimensional accuracy, surface roughness, and surface layer quality meet the design requirements. The workpiece may be a blank or a semi-finished product. During the production of automobile parts, the blank or semi-finished parts need to be finely processed by cutting.

[0003] For example, the existing patent publication number CN217254868U provides a purging device for cutting of automobile parts, including a box body. A fixed plate is fixedly arranged inside the box body. A first motor is fixedly connected to the upper surface of the fixed plate. One end of the first motor is fixedly connected to a rotating shaft. A rocker is arranged on the outer surface of the rotating shaft. One end of the rocker is provided with a push rod. One end of the push rod is connected with a push block. The rotating shaft is movably connected with the rocker. The rocker is movably connected with the push rod. The push rod is movably connected with the upper surface of the fixed plate. By starting the set first motor to rotate, the rotating shaft rotates, the rotating shaft drives the rocker to rotate, the rocker drives the push rod to move, the push rod drives the push block to move, and the push block moves back and forth on the surface of the fixed plate to drive the purging device to move back and forth, so that the processing part of the parts is kept clean, and the waste is discharged into the collection box through the purging device for centralized treatment of the waste.

[0004] In the above device, the purged chips are finally discharged into the collection box for collection. The form of the chips generated during the cutting process of the parts is affected by various factors such as the tool tip and the feed rate. When the cutting feed rate is large, the chips are extremely easy to separate from the parts in the form of strip-shaped twist. The long strip-shaped chips may be horizontally placed above the feed port of the collection box under the action of the purging device, and a certain blockage of the feed port of the collection box is generated. The generation of this blockage will increase the difficulty of the waste during the purging process to enter the collection box, and then cause the chips to splash in the processing space, affecting the purging quality of the purging device for the chip device.

[0005] Therefore, a purging device for cutting waste of automobile parts is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the problem that when the cutting feed rate is large, the debris is extremely likely to appear in the shape of a strip and separate from the part. This long strip of debris may be horizontally placed above the feed port of the collection box under the action of the purging device, and will block the feed port of the collection box to a certain extent. The generation of this blockage will increase the difficulty of the waste during the purging process to enter the collection box, and then cause the debris to splash in the processing space, affecting the purging quality of the purging device for the chip device. A purging device for cutting waste of automotive parts is proposed.

[0025] The following gives specific embodiments.

[0026] Please refer to Figure 1 - Figure 4 , the present utility model provides a purging device for cutting waste of automotive parts, including a part table 1. At the center of one side of the bottom surface of the part table 1, a guide rod sleeve 11 is fixedly connected. One end of the part table 1 is provided with a purging assembly 2. The purging assembly 2 includes a lead screw main body 21. Both ends of the lead screw main body 21 are installed with lead screw brackets 22 through bearings. The bottom surfaces of the two lead screw brackets 22 are vertically and fixedly connected to the top surface of the part table 1. A threaded sleeve 23 is externally threaded on the lead screw main body 21. A purging head 24 is installed on the outer wall of the threaded sleeve 23. The other end of the part table 1 is provided with a collection assembly 3. The collection assembly 3 includes a collection box 31. The collection box 31 is located below the part table 1. A limit rod 311 is fixedly connected to the center of the side wall of the collection box 31 close to the purging assembly 2. The limit rod 311 is slidably installed between the inner walls of the guide rod sleeve 11. A material scraping assembly 32 is installed inside the collection box 31. When cutting and processing automotive parts, the part to be processed is placed on the top of the part table 1, and the part is squeezed and fixed under the cooperation of the clamping plate and its upper track. Then, it is cut and processed by a cutting device. After debris is generated during the processing, the purging assembly 2 is activated to purge the debris into the range of action of the collection assembly 3. Among them, the lead screw main body 21 and the lead screw brackets 22 cooperate to be relatively fixed to the part table 1, and the lead screw main body 21 installs the threaded sleeve 23 and the purging head 24. An air pump is connected to the purging head 24 to provide purging air for it. The relative positions of the threaded sleeve 23 and the purging head 24 can be adjusted within a certain range by rotating the lead screw main body 21. The collection box 31 is linked with the part table 1 through the mutual cooperation of the limit rod 311 and the guide rod sleeve 11. Before the part is placed on the part table 1, the entire collection assembly 3 can be pulled outwards to prevent the protruding side wall of the collection assembly 3 from hindering the installation of the part. And the twist-shaped debris can be scraped into the inside of the collection box 31 under the cooperation of the material scraping assembly 32;

[0027] Such as Figure 1 、 Figure 2 and Figure 3As shown, the material scraping assembly 32 includes a rotating shaft rod 321. Both ends of the rotating shaft rod 321 are perpendicularly and fixedly connected to the inner walls on both sides of the collection box 31 through bearings. A plurality of scraping claws 322 are installed on the outer wall of the rotating shaft rod 321. The plurality of scraping claws 322 are equidistantly installed along the axial direction of the rotating shaft rod 321. A plurality of material discharging inclined plates 323 are fixedly connected to the side wall of the collection box 31 away from the part table 1. The plurality of material discharging inclined plates 323 are coplanar. The plurality of material discharging inclined plates 323 are respectively located between the adjacent side walls of two adjacent scraping claws 322. A first motor 33 is installed on one end side wall of the collection box 31. The output shaft of the first motor 33 is connected to the axis of the rotating shaft rod 321. A draw box 34 is slidably installed between the inner walls of the open end of the collection box 31. The debris entering the collection box 31 is collected by the draw box 34. The first motor 33 provides a rotational output force for the rotating shaft rod 321 and the scraping claws 322. During the rotation process, the scraping claws 322 can scrape the strip-shaped debris into the interior of the collection box 31. The material discharging inclined plates 323 can push out the debris that may be wound around the outer wall of the scraping claws 322 during the overall rotation of the rotating shaft rod 321 and the scraping claws 322, increasing the rationality of the material scraping of the material scraping assembly 32. Moreover, the inclined structure feature of the material discharging inclined plates 323 prevents the debris from accumulating on its top surface, increasing the rationality of the device structure;

[0028] As Figure 2 shown, a second motor 4 is installed on the side wall of one of the screw rod brackets 22. The output shaft of the second motor 4 is connected to the axis of the screw rod body 21. By controlling the opening and closing of the second motor 4, the screw rod body 21 rotates, thereby controlling the relative positions of the threaded sleeve 23 and the blowing head 24 on the screw rod body 21;

[0029] As Figure 1 、 Figure 2 and Figure 4 shown, a rotating guide rod 25 is installed through the outer wall of the threaded sleeve 23 through a bracket. One end of the rotating guide rod 25 is fixedly connected with a limiting circular plate 251. An arc-shaped limiting frame 221 is sleeved on the outer wall of the limiting circular plate 251. The arc-shaped limiting frame 221 is fixedly connected with one of the screw rod brackets 22. An arc-shaped opening 222 is formed on the side wall of the other screw rod bracket 22. An extrusion nut 26 is installed on the outer thread of one end of the rotating guide rod 25. The extrusion nut 26 contacts the screw rod bracket 22. The threaded sleeve 23 is linked with the rotating guide rod 25. The rotating guide rod 25 is linked with the screw rod bracket 22 and the threaded sleeve 23 under the cooperation of the limiting circular plate 251, the arc-shaped limiting frame 221 and the arc-shaped opening 222. When the spiral extrusion nut 26 squeezes the outer wall of the arc-shaped opening 222, the relative position of the rotating guide rod 25 is fixed. At this time, during the process of hanging on the screw rod body 21, the relative positions of the threaded sleeve 23 and the blowing head 24 are fixed. When it is necessary to change the blowing angle of the blowing head 24, flip the extrusion nut 26 to release its extrusion force on the screw rod bracket 22. At this time, the relative position of the whole rotating guide rod 25 can be changed, thereby changing the blowing angle of the blowing head 24;

[0030] Working principle: When machining automotive parts, the part to be machined is placed on the top of the part table 1 and is squeezed and fixed by the cooperation of the clamping plate and its upper track. Then, the cutting device is used to machine it. After debris is generated during the machining process, the purging assembly 2 is activated to purge the debris into the range of the collection assembly 3. The lead screw body 21 and the lead screw bracket 22 cooperate to be relatively fixed to the part table 1, and the lead screw body 21 mounts the threaded sleeve 23 and the purging head 24. The air pump is connected to the purging head 24 to provide purging air for it. The relative positions of the threaded sleeve 23 and the purging head 24 can be adjusted within a certain range by rotating the lead screw body 21. The collection box 31 is linked to the part table 1 through the mutual cooperation of the limit rod 311 and the guide rod sleeve 11. The debris entering the collection box 31 is collected by the pull box 34. The first motor 33 provides a rotational output force for the rotating shaft rod 321 and the claw 322. The twist-shaped debris can be scraped into the interior of the collection box 31 by the cooperation of the material scraping assembly 32. The strip-shaped debris is scraped into the interior of the collection box 31. The material discharging inclined plate 323 can push out the debris that may be wound around the outer wall of the claw 322 during the overall rotation of the rotating shaft rod 321 and the claw 322. By opening and closing the second motor 4, the lead screw body 21 is rotated, and thus the relative positions of the threaded sleeve 23 and the purging head 24 on the lead screw body 21 are controlled. The threaded sleeve 23 is linked to the rotating guide rod 25. The rotating guide rod 25 is linked to the lead screw bracket 22 and the threaded sleeve 23 through the cooperation of the limit circular plate 251, the arc-shaped limit frame 221, and the arc-shaped opening 222. When the spiral extrusion nut 26 squeezes the outer wall of the arc-shaped opening 222, the relative position of the rotating guide rod 25 is fixed. At this time, during the process of hanging on the lead screw body 21, the relative positions of the threaded sleeve 23 and the purging head 24 are fixed. When it is necessary to change the purging angle of the purging head 24, the flipping extrusion nut 26 releases its extrusion force on the lead screw bracket 22. At this time, the relative position of the entire rotating guide rod 25 can be changed, and thus the purging angle of the purging head 24 can be changed.
