Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing production, in particular to an automatic chip sweeping device and a processing production line using the device. Background Art

[0002] In modern mechanical processing production lines, the operation of machine tools will inevitably generate a large amount of iron chips. These iron chips are generated by the relative movement between the tool and the workpiece during the metal cutting process. As the processing continues, the amount of iron chips will continue to accumulate. If they are not cleaned up in time, they may have a negative impact on the normal operation of the machine tool and the quality of the processed products. Therefore, the cleaning of iron chips occupies an important position in the processing production line.

[0003] At present, the existing technology mainly relies on manual cleaning of iron filings generated on the processing production line. Specifically, when the machine tool workbench moves to a certain position, the production line needs to be suspended, and then the worker will hold a cleaning tool to clean the iron filings on the workbench.

[0004] The inventors found during implementation that the above-mentioned prior art has at least the following defects: since the manual cleaning of iron filings requires stopping the production line, the production efficiency of the processing production line will be affected. Summary of the invention

[0005] The embodiment of the present application solves the technical problem that the iron chips in the processing production line need to be manually cleaned by providing an automatic chip sweeping device and a processing production line using the device, thereby improving the production efficiency of the processing production line.

[0006] In order to solve the above technical problems, the present invention adopts the following technical scheme: an automatic chip sweeping device, comprising a cleaning bracket, a track bracket and a flip guard plate installed on a workbench B, wherein the cleaning bracket and the track bracket are respectively fixed on the edges of the machine pit on both sides of the moving direction of the workbench B, the outer side of the flip guard plate is located outside the edge of the workbench B, a connecting rod is fixed on the flip guard plate, one end of the connecting rod extends out of the flip guard plate and extends in a direction perpendicular to the moving direction of the workbench B, the end of the connecting rod extending out of the flip guard plate can contact the bottom of the track bracket, and the track bracket is inclined along the moving direction of the workbench B. Since the cleaning bracket and the track bracket inclined along the moving direction of the workbench B are fixed on the edge of the machine pit, the flip guard plate is installed on the workbench B, the connecting rod is fixed on the flip guard plate, and the end of the connecting rod can contact the bottom of the track bracket, so as the workbench B moves, the flip guard plate will be driven by the connecting rod to flip relative to the table surface of the workbench B, and the iron chips above it will be cleaned to the bottom of the workbench B. At the same time, when the workbench B passes, the cleaning bracket can also sweep the iron chips on the other side of the surface of the workbench B. The device can clean up the iron filings on the production line in time without stopping the production line, thereby improving production efficiency.

[0007] As a further improvement of the above scheme, the cleaning bracket includes a supporting part and a cleaning part, the lower end of the supporting part is fixed to the edge of the machine tool pit, the cleaning part is arranged horizontally and one end of the cleaning part is fixed to the supporting part, when the workbench B passes by, the cleaning part can contact with the table surface of the workbench B; the cleaning bracket can effectively utilize the space at the edge of the machine tool pit, by fixing the supporting part and the horizontally arranged cleaning part, it is ensured that when the workbench B moves by, the cleaning part can automatically contact and clean the table surface of the workbench B, which saves space and realizes real-time cleaning and maintenance.

[0008] As a further improvement of the above solution, the flip guard plate is hinged to the edge of the workbench B.

[0009] As a further improvement of the above scheme, the flip guard plate includes a horizontal section and an inclined section. When the horizontal section is parallel to the plane of the workbench B, the inclined section tilts downward from the top of the workbench B, and the edge of the workbench B is hinged to the bottom of the inclined section; thus, the inclined section provides a downward inclined guide for the edge of the workbench B, which can facilitate the sliding of iron filings.

[0010] As a further improvement of the above scheme, a connecting seat is fixed to the edge of the workbench B, a pin shaft runs through the connecting seat, and the pin shaft is connected to the bottom of the inclined section of the flip guard plate; thereby, the stability of the flip guard plate can be improved, and at the same time, it is convenient to flip and tilt as needed.

[0011] As a further improvement of the above solution, a roller is installed on the outside of the connecting rod; when the roller contacts the bottom of the track bracket, it can roll instead of slide, which is conducive to the flipping of the flip guard plate.

[0012] As a further improvement of the above scheme, the track bracket is in the shape of a slide, the head end of the track bracket is higher than the end of the track bracket, and the end of the track bracket is fixed to the edge of the machine tool pit; the slide-shaped track bracket can help guide the connecting rod to slide from a high place to a low place, thereby achieving smooth displacement control.

[0013] As a further improvement of the above scheme, the rail bracket is fixed to the edge of the machine tool pit through a corner-shaped fixed bracket, the side of the fixed bracket is fixed to the side wall of the edge of the machine tool pit, and the top of the fixed bracket is fixed to the bottom of the end of the rail bracket; thereby, a stable supporting structure can be formed to increase the service life of the device.

[0014] As a further improvement of the above solution, the cleaning bracket and the track bracket are both located at one end of the moving direction of the workbench B.

[0015] The invention also discloses a processing production line, which adopts the automatic chip sweeping device as described above.

[0016] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: Since a cleaning bracket and a track bracket tilted along the moving direction of workbench B are fixed on the edge of the machine pit, a flip guard plate is installed on workbench B, a connecting rod is fixed on the flip guard plate, and the end of the connecting rod can contact the bottom of the track bracket, so as workbench B moves, the flip guard plate will be driven by the connecting rod to flip relative to the table of workbench B, and the iron filings above it will be cleaned to the bottom of workbench B. At the same time, when workbench B passes by, the cleaning bracket can also sweep the iron filings on the other side of the surface of workbench B. The device can clean the iron filings on the production line in time without stopping the production line, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments of the present invention.

DETAILED DESCRIPTION In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] In order to better understand the improvements made by the present invention relative to the prior art, before describing the two specific implementation modes of the present invention in detail, the prior art mentioned in the background technology section is first described.

[0020] During the operation of the machine tool, the tool and the workpiece move relative to each other, and the excess material on the workpiece is removed through the principle of cutting processing. For example, during turning, the workpiece rotates and the tool cuts; during milling, the milling cutter rotates and the workpiece feeds; during drilling, the drill bit rotates and feeds axially. During the material removal process, due to the different characteristics of the materials, soft materials are mainly sheared and deformed under the action of the tool. For example, when cutting soft steel, the iron chips are relatively continuous; brittle materials such as cast iron will be broken and removed because they cannot withstand large plastic deformation, resulting in broken iron chips. These removed materials form the iron chips during the operation of the machine tool.

[0021] Figure 1 FIG. 1 shows a partial structural schematic diagram of a processing production line in the prior art, such as Figure 1 As shown, the workbench A13 moves on the machine tool, and a chip conveyor is provided below the workbench A13. When there are many iron chips above the workbench A13, the line needs to be stopped and then manually cleaned to clean the iron chips into the chip conveyor below. In this process, since the line needs to be stopped and then manually cleaned, the production efficiency is affected.

[0022] The three specific embodiments of the present invention are improvements made to solve the problem that the processing production line in the prior art cannot automatically clean up the iron chips. The three specific embodiments are described in detail below.

[0023] Example 1 Figure 2For the sake of simplicity, the figure only shows the foundation of the processing production line, the workbench B10 and the automatic chip sweeping device that cooperates with the two, and omits the guide rails and other structures below the workbench B10. Figure 3 It is also a schematic diagram of the structure of the present invention, and its viewing angle is a side view along the moving direction of the workbench B10. Figure 4 Yes means Figure 3 A is an enlarged schematic diagram of the structure within the circle.

[0024] For the convenience of description, the "left" and "right" referred to below are consistent with the left and right directions of the drawings themselves, but do not limit the structure of this embodiment. In addition, for the sake of simplicity, in this embodiment, Figure 2 The direction of the middle arrow is defined as the moving direction of workbench B10, i.e., the direction of trolley exchange.

[0025] like Figures 2 to 4 As shown, this embodiment discloses an automatic chip sweeping device, which includes a cleaning bracket 8, a track bracket 5, and a flip guard plate 2 installed on a workbench B10. The cleaning bracket 8 is used to clean the iron chips on one side of the workbench B10, and the flip guard plate 2 can cooperate with the track bracket 5 to clean the iron chips on the other side of the workbench B10. When the workbench B10 moves along its moving direction, the table surface on one side passes under the cleaning bracket 8. During this process, the cleaning bracket 8 can sweep the iron chips on the workbench B10 into the chip conveyor below the workbench B10. In addition, during the operation of the machine tool, a part of the iron chips will fall onto the flip guard plate 2. When the workbench B10 moves to one end along its moving direction, the flip guard plate 2 will flip around the edge of the other side of the workbench B10, so that the iron chips above it slide into the chip conveyor below the workbench B10.

[0026] like Figure 2 and Figure 3 As shown, the cleaning bracket 8 and the track bracket 5 are respectively fixed on the edges of the machine pit 11 on both sides of the movable workbench B10. The outer side of the flip guard plate 2 protrudes out of the edge of the workbench B10 so that it can be flipped relative to the table top of the workbench B10, thereby achieving the sliding of iron filings. After the outer side of the flip guard plate 2 protrudes out of the edge of the workbench B10, it is also connected to the roller 4, which is used to cooperate with the track bracket 5, wherein the track bracket 5 is set at an angle. Figure 2 As shown, the left end of the track bracket 5 is high and the right end is low. When the workbench B10 moves to this position, on the one hand, the cleaning bracket 8 sweeps off the iron filings on the table surface on one side thereof; on the other hand, the roller 4 connected to the flip guard plate 2 contacts the track bracket 5, and the roller 4 moves along the track bracket 5 and its height gradually decreases, thereby driving the flip guard plate 2 to flip relative to the table surface of the workbench B10, thereby achieving the sliding of the iron filings on the flip guard plate 2.

[0027] The cleaning bracket 8 includes a supporting portion 7 and a cleaning portion. The supporting portion 7 is used to fix the cleaning bracket 8 itself to the edge of the machine pit 11, and the cleaning portion is used to clean the iron filings on the workbench B10. Figure 2 , Figure 3 As shown, the lower end of the support portion 7 can be fixed to the edge of the machine pit 11 by bolts or other methods such as pre-embedding, and the upper end of the support portion 7 is fixedly connected to the cleaning portion. The cleaning portion is arranged horizontally, and its height is slightly higher than the table surface of the workbench B10, so that when the workbench B10 passes under the cleaning bracket 8, the cleaning portion can sweep away the iron filings on the table surface. In addition, the support portion 7 and the cleaning portion of the cleaning bracket 8 can both be made of angle steel.

[0028] The cleaning bracket 8 is used to clean the iron filings on one side above the workbench B10, while the iron filings on the other side of the workbench B10 fall on the flip guard plate 2, and the iron filings slide down by flipping the flip guard plate 2. The flip guard plate 2 is hinged to the edge of the workbench B10, wherein a connecting seat 3 is fixed at the edge of the workbench B10, and a pin shaft 9 is passed through the connecting seat 3, and the pin shaft 9 is connected to the bottom of the flip guard plate 2. The bottom of the flip guard plate 2 can also be provided with a mounting seat for the pin shaft 9 to pass through, so that the flipping of the flip guard plate 2 relative to the workbench B10 can be achieved through the cooperation of the connecting seat 3 and the mounting seat.

[0029] like Figure 3 As shown, the flip guard plate 2 includes a horizontal section and an inclined section. The horizontal section is located above the workbench B10. The bottom of the inclined section is hinged to the edge of the workbench B10 and the inclined section extends out of the edge of the workbench B10. The angle between the horizontal section and the inclined section is an obtuse angle. When the horizontal section is parallel to the table surface of the workbench B10, the inclined section tilts downward from the top of the workbench B10 to a certain slope. During the operation of the machine tool, most of the iron filings generated by the tool cutting fall on the horizontal section of the flip guard plate 2. When the flip guard plate 2 flips, a certain slope is formed between the horizontal section and the table surface of the workbench B10, so that the iron filings above it slide down along the slope to the inclined section. Since the inclined section and the horizontal section themselves have a certain angle, the iron filings above the inclined section will slide down to the chip conveyor below the workbench B10 at a faster speed. It can be seen that the setting of the inclined section can make the iron filings above the flip slide slide faster, which is conducive to cleaning the iron filings on the flip guard plate 2 more cleanly.

[0030] The bottom of the flip guard plate 2 is connected with a connecting rod 12, one end of the connecting rod 12 extends out of the flip guard plate 2, and the roller 4 is installed outside the connecting rod 12, and the outer periphery of the roller 4 can contact the bottom of the track bracket 5. Since the track bracket 5 is inclined, the position of the roller 4 and the connecting rod 12 will be lowered with the track bracket 5, thereby driving the flip guard plate 2 to flip.

[0031] Example 2 See also Figures 2 to 5 ,in Figure 5 It is a three-dimensional structural schematic diagram of the present invention. For the sake of simplicity, Figure 5 Similarly, only the foundation of the processing production line, the workbench B10 and the automatic chip sweeping device that cooperates with the two are shown, and the guide rails and other structures under the workbench B10 are also omitted.

[0032] For the convenience of description, the "left" and "right" referred to below are consistent with the left and right directions of the drawings themselves, but do not limit the structure of this embodiment. In addition, for the sake of simplicity, in this embodiment, Figure 2 The direction of the middle arrow is defined as the moving direction of workbench B10, i.e., the direction of trolley exchange.

[0033] The present embodiment discloses an automatic chip sweeping device, which includes a cleaning bracket 8, a track bracket 5, and a flip guard plate 2 installed on a workbench B10. The cleaning bracket 8 is used to clean the iron chips on one side of the workbench B10, and the flip guard plate 2 can cooperate with the track bracket 5 to clean the iron chips on the other side of the workbench B10. When the workbench B10 moves along its moving direction, the table surface on one side passes under the cleaning bracket 8. During this process, the cleaning bracket 8 can sweep the iron chips on the workbench B10 into the chip conveyor below the workbench B10. In addition, during the operation of the machine tool, a part of the iron chips will fall onto the flip guard plate 2. When the workbench B10 moves to one end along its moving direction, the flip guard plate 2 will flip around the edge of the other side of the workbench B10, so that the iron chips above it slide into the chip conveyor below the workbench B10.

[0034] like Figure 2 and Figure 3 As shown, the cleaning bracket 8 and the track bracket 5 are respectively fixed on the edges of the machine pit 11 on both sides of the movable workbench B10. The outer side of the flip guard plate 2 protrudes out of the edge of the workbench B10 so that it can be flipped relative to the table top of the workbench B10, thereby achieving the sliding of iron filings. After the outer side of the flip guard plate 2 protrudes out of the edge of the workbench B10, it is also connected to the roller 4, which is used to cooperate with the track bracket 5, wherein the track bracket 5 is set at an angle. Figure 2 As shown, the left end of the track bracket 5 is high and the right end is low. When the workbench B10 moves to this position, on the one hand, the cleaning bracket 8 sweeps off the iron filings on the table surface on one side thereof; on the other hand, the roller 4 connected to the flip guard plate 2 contacts the track bracket 5, and the roller 4 moves along the track bracket 5 and its height gradually decreases, thereby driving the flip guard plate 2 to flip relative to the table surface of the workbench B10, thereby achieving the sliding of the iron filings on the flip guard plate 2.

[0035] The cleaning bracket 8 includes a supporting portion 7 and a cleaning portion. The supporting portion 7 is used to fix the cleaning bracket 8 itself to the edge of the machine pit 11, and the cleaning portion is used to clean the iron filings on the workbench B10. Figure 2 , Figure 3 As shown, the lower end of the support portion 7 can be fixed to the edge of the machine pit 11 by bolts or other methods such as pre-embedding, and the upper end of the support portion 7 is fixedly connected to the cleaning portion. The cleaning portion is arranged horizontally, and its height is slightly higher than the table surface of the workbench B10, so that when the workbench B10 passes under the cleaning bracket 8, the cleaning portion can sweep away the iron filings on the table surface. In addition, the support portion 7 and the cleaning portion of the cleaning bracket 8 can both be made of angle steel.

[0036] The cleaning bracket 8 is used to clean the iron filings on one side above the workbench B10, while the iron filings on the other side of the workbench B10 fall on the flip guard plate 2, and the iron filings slide down by flipping the flip guard plate 2. The flip guard plate 2 is hinged to the edge of the workbench B10, wherein a connecting seat 3 is fixed at the edge of the workbench B10, and a pin shaft 9 is passed through the connecting seat 3, and the pin shaft 9 is connected to the bottom of the flip guard plate 2. The bottom of the flip guard plate 2 can also be provided with a mounting seat for the pin shaft 9 to pass through, so that the flipping of the flip guard plate 2 relative to the workbench B10 can be achieved through the cooperation of the connecting seat 3 and the mounting seat.

[0037] like Figure 3 As shown, the flip guard plate 2 includes a horizontal section and an inclined section. The horizontal section is located above the workbench B10. The bottom of the inclined section is hinged to the edge of the workbench B10 and the inclined section extends out of the edge of the workbench B10. The angle between the horizontal section and the inclined section is an obtuse angle. When the horizontal section is parallel to the table surface of the workbench B10, the inclined section tilts downward from the top of the workbench B10 to a certain slope. During the operation of the machine tool, most of the iron filings generated by the tool cutting fall on the horizontal section of the flip guard plate 2. When the flip guard plate 2 flips, a certain slope is formed between the horizontal section and the table surface of the workbench B10, so that the iron filings above it slide down along the slope to the inclined section. Since the inclined section and the horizontal section themselves have a certain angle, the iron filings above the inclined section will slide down to the chip conveyor below the workbench B10 at a faster speed. It can be seen that the setting of the inclined section can make the iron filings above the flip slide slide faster, which is conducive to cleaning the iron filings on the flip guard plate 2 more cleanly.

[0038] The bottom of the flip guard plate 2 is connected with a connecting rod 12, one end of the connecting rod 12 extends out of the flip guard plate 2, and the roller 4 is installed outside the connecting rod 12, and the outer periphery of the roller 4 can contact the bottom of the track bracket 5. Since the track bracket 5 is inclined, the position of the roller 4 and the connecting rod 12 will be lowered with the track bracket 5, thereby driving the flip guard plate 2 to flip.

[0039] like Figure 5 As shown, the track bracket 5 is in the shape of a slide, and the first end of the track bracket 5 (corresponding to Figure 2 The left end of the middle track bracket 5) is higher than the end of the track bracket 5 (corresponding to Figure 2 The right end of the middle track bracket 5), the end of the track bracket 5 is fixed to the edge of the machine pit 11. In this embodiment, the track bracket 5 is fixed to the edge of the bed pit by fixing the bracket 1 (such as Figure 2 As shown), specifically, the fixed bracket 1 is corner-shaped, the side of the fixed bracket 1 is fixed to the side wall of the edge of the machine tool pit 11, and the top of the fixed bracket 1 is fixed to the bottom of the end of the track bracket 5 by screws 6, thereby improving the reliability between the tracks.

[0040] It should be understood that when the flip guard plate 2 is not in a flipping state, the roller 4 does not contact the bottom of the track bracket 5, and the height of the head end of the track bracket 5 is slightly higher than the height of the roller 4. When the workbench B10 moves to a position close to the end of its track, the roller 4 begins to contact the bottom of the head end of the track bracket 5, and as the workbench B10 continues to move forward, the roller 4 or the connecting rod 12 contacts the bottom of the track bracket 5. The setting of the roller 4 enables it to cut into the bottom of the track bracket 5 more smoothly, but as the flip guard plate 2 flips, the connecting rod 12 will tilt accordingly, so the roller 4 can be set on the side of the outer periphery of the connecting rod 12 relatively close to the flip guard plate 2, thereby effectively avoiding friction between the connecting rod 12 and the track bracket 5, making the flip of the flip guard plate 2 smoother.

[0041] Example 3 This embodiment discloses a processing production line, which adopts the automatic chip sweeping device as described in Example 1 or Example 2.

[0042] The terms "connected" and "connected" in the present invention should be understood in a broad sense. For example, it can be a connection or a detachable connection; it can be a direct connection or an indirect connection through an intermediate component. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in their embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novelties disclosed herein.
