Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, and specifically to a precision grinding machine with air drying function. Background Technology

[0002] Grinding machines play an important role in the processing and manufacturing process. When using a CNC indexable insert grinder to grind carbide CNC inserts, the parts inside need to be replaced and cleaned every once in a while due to long-term wear.

[0003] Most existing grinding machines use cutting fluid to cool the machine during the grinding process. However, the high speed of grinding causes the coolant to splash onto various parts of the machine. As a result, after each machining operation, the operator needs to clean the inside of the grinding machine and the cutting tools. Since the cutting fluid itself has a certain corrosive effect, if it is not cleaned for a long time, it will reduce the accuracy of the cutting tools and even affect the overall processing capacity of the machine tool. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precision grinding machine with air drying function. This addresses the technical problem that the high-speed machining of the grinding machine causes coolant to splash onto various parts of the machine, requiring operators to clean the interior of the grinding machine and the cutting tools after each machining operation. Since the cutting coolant itself has a certain corrosive effect, prolonged neglect of cleaning can reduce the precision of the cutting tools machined on the grinding machine, and even affect the overall machining capacity of the machine tool.

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

[0006] A finishing grinding machine with air drying function includes a worktable with a groove on its upper surface. An isolation box for preventing chip ejection is fixed above the groove. A horizontal first elongated groove is provided on each of the inner walls of the groove, with the two first elongated grooves at the same height and opening opposite each other. A work plate is slidably connected within the two first elongated grooves. A first motor is mounted on the rear wall of the worktable, and a first rotating shaft with a lead screw structure is fixed to the output end of the first motor. The first rotating shaft passes through the rear wall of the worktable, enters one of the first elongated grooves, and is screwed to the work plate. The portion of the first rotating shaft that contacts the worktable is a smooth circular section, and the portion that contacts the work plate is a lead screw structure. The worktable is equipped with a clamping assembly for fixing the workpiece to be processed. The inner wall of the isolation box is equipped with a second translation assembly, which is connected to a third translation assembly. The third translation assembly is equipped with a grinding assembly and is used to drive the grinding assembly to move along the length of the worktable. The second translation assembly drives the third translation assembly to move along the width of the isolation box. The isolation box is also equipped with a spraying assembly for cooling the workpiece, which is used to spray cutting fluid onto the tool of the grinding assembly. An extension plate is fixedly installed on one side of the worktable, and a water tank is also provided on the extension plate. A squeezing mechanism is provided between the water tank and the third translation assembly to spray clean water from the water tank into the isolation box.

[0007] Working principle:

[0008] When it is necessary to remove the processed isolation box and cutting fluid, the operator first places the workpiece into the clamping assembly for secure clamping. Then, the operator starts the first motor, which drives the first rotating shaft to rotate. The first rotating shaft moves the workplate back and forth, and the workplate moves the workpiece on the clamping assembly. Next, the operator starts the second translation assembly, which moves the third translation assembly and the grinding assembly to a suitable position. At this time, the third translation assembly is started, which moves the grinding assembly to the side of the workpiece to be processed. Simultaneously, the grinding assembly is started to process the workpiece. During the processing, the operator starts the fluid spraying assembly. The cutting fluid sprayed by the fluid spraying assembly cools the cutting tool of the grinding assembly. During the cooling process... The cutting fluid will splash into the isolation box and the worktable. After the workpiece is finished, it is removed from the clamping assembly. At this time, the tool on the grinding assembly needs to be returned to its original position. The operator simultaneously starts the second and third translation components. The second translation component drives the third translation component to move. Then, the third translation component drives the grinding assembly to move. When the third translation component drives the grinding assembly back to its original position, the grinding assembly applies pressure to the extrusion mechanism. At this time, the extrusion mechanism sprays clean water from the water tank into the grooves of the isolation box and the worktable until the cutting fluid splashed into the grooves of the worktable and the isolation box during processing is diluted. Finally, when the grinding assembly returns to its original position, the clean water in the water tank has been sprayed out. Then, the operator heats and dries the space inside the isolation box and the worktable.

[0009] The beneficial effects of this invention are as follows:

[0010] Compared to existing technologies, when it is necessary to clean the isolation box and cutting fluid after machining, the operator only needs to retract the grinding assembly back to its original position. The operator then simultaneously activates the second and third translation components. The second translation component moves the third translation component, which in turn moves the grinding assembly. When the grinding assembly returns to its original position, it applies pressure to the extrusion mechanism. At this time, the extrusion mechanism sprays clean water from the water tank into the grooves of the isolation box and the worktable, until the cutting fluid splashed into the grooves of the worktable and the isolation box during machining is diluted. Finally, when the grinding assembly returns to its original position, the clean water in the water tank has been sprayed out. Then, the operator heats and dries the space inside the isolation box and the worktable. This method effectively cleans the tools and the inside of the grinding machine, reducing the waste of manpower and resources. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1As shown, a precision grinding machine with air drying function includes a worktable 1. The upper surface of the worktable 1 has a groove 3. An isolation box 2 for preventing chip ejection is fixed above the groove 3. A horizontal first elongated groove 4 is provided on each of the inner walls of the groove 3. The two first elongated grooves 4 are at the same height and their openings face each other. A work plate 5 is slidably connected within the two first elongated grooves 4. A first motor 6 is provided on the rear wall of the worktable 1. A first rotating shaft 7, which is a lead screw structure, is fixed to the output end of the first motor 6. The first rotating shaft 7 passes through the rear wall of the worktable 1. The first rotating shaft 7 is inserted into one of the first elongated grooves 4 and screwed to the work plate 5. The part of the first rotating shaft 7 that contacts the worktable 1 is a smooth circular section, and the part of the first rotating shaft 7 that contacts the work plate 5 is a lead screw structure. The work plate 5 is provided with a clamping assembly for fixing the workpiece to be processed. The clamping assembly includes a clamping seat 46 with a clamping groove, a bolt 47 and a clamping plate 48. The clamping seat 46 is fixedly installed on the work plate 5. The bolt 47 passes through the clamping seat 46. The clamping plate 48 is fixedly installed on the bolt 47 and located in the clamping groove. The first rotating shaft 7 is divided into a smooth circular section and a lead screw section.

[0018] When it is necessary to remove the finished isolation box 2 and cutting fluid, the operator first places the workpiece into the clamping slot in the clamping seat 46. Then, the operator rotates the bolt 47, which moves the clamping plate 48 within the clamping slot until the clamping plate 48 secures the workpiece. Next, the operator starts the first motor 6, which drives the first rotating shaft 7 to rotate. The first rotating shaft 7 moves the work plate 5 back and forth, causing the workpiece on the clamping assembly to move. Then, the operator starts the second translation assembly, which moves the third translation assembly and the grinding assembly to a suitable position. At this point, the third translation assembly is started, moving the grinding assembly to the side of the workpiece to be processed. Simultaneously, the grinding assembly is started, and it processes the workpiece. During processing, the operator starts the spraying assembly, which sprays cutting fluid onto the rotating workpiece. The cutting tool of the grinding assembly is cooled down. During the cooling process, the cutting fluid splashes into the isolation box 2 and the worktable 1. At this time, after the workpiece is finished, it is removed from the clamping assembly. The cutting tool on the grinding assembly needs to be returned to its original position. The operator simultaneously starts the second translation assembly and the third translation assembly. The second translation assembly drives the third translation assembly to move. Then, the third translation assembly drives the grinding assembly to move. When the third translation assembly returns to its original position, the grinding assembly applies pressure to the extrusion mechanism. At this time, the extrusion mechanism sprays clean water from the water tank 43 into the groove 3 of the isolation box 2 and the worktable 1 until the cutting fluid splashed into the groove 3 of the worktable 1 and the isolation box 2 during processing is diluted by the clean water. Finally, when the grinding assembly returns to its original position, the clean water in the water tank 43 has been sprayed out. Then, the operator heats and dries the space inside the isolation box 2 and the worktable 1.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, a second translation component is provided on the inner wall of the isolation box 2. The second translation component includes a second motor 10, a first guide rail 11, a second rotating shaft 12 with a lead screw structure, and a first guide block 13.

An extension plate 8 is fixedly installed on one side of the worktable 1. A water storage tank 43 is also provided on the extension plate 8. A squeezing mechanism for spraying clean water from the water storage tank 43 into the isolation box 2 is provided between the water storage tank 43 and the third translation assembly. The squeezing mechanism includes a squeezing rod 26, a crossbar 27, a rotating shaft 28, a collar 29, a first rack 30, a second rack 31, a first gear 32, a spray ball head 33, a transmission pipe 34, and a second gear. One end of the squeezing rod 26 is fixedly mounted on one side of the fourth motor 18, and a collar 29 is fixedly fitted on the other end. A second elongated groove 44 is provided on one side of the crossbar 27, and the squeezing rod 26... The other end of 6 is slidably installed in the second elongated groove 44, and a third elongated groove 45 is provided along the side wall of the second elongated groove 44. The collar 29 is slidably installed in the third elongated groove 45. The isolation box 2 has a through hole 49 and also includes a slide rail 54, a moving plate 55 and a sliding groove 50. The slide rail 54 is laid longitudinally in the through hole 49. The moving plate 55 is slidably installed on the slide rail 54, and the moving plate 55 has a sliding groove 50. The first rack 30 is slidably installed in the sliding groove 50. The first rack 30 is slidably installed on the sliding groove 50 and passes through the water storage tank 43. The first rack 30 is fixed to the crossbar 27. The rotating shaft 28 The two ends of the shaft 28 are rotatably connected to the two side walls of the water storage tank 43. The first gear 32 is fixedly sleeved at one end of the shaft 28 and meshes with the first rack 30. The second gear is fixedly sleeved at the other end of the shaft 28. A vertical groove 42 is provided in the side wall of the water storage tank 43. The second rack 31 is vertically slidably disposed in the vertical groove 42, and the second gear meshes with the second rack 31. One end of the transmission pipe 34 is connected to the water storage tank 43, and the other end passes through the isolation box 2 and is located behind the grinding tool 20. The jet ball head 33 is fixedly installed on the other end of the transmission pipe 34. The device also includes a heating source 36, a self-resetting switch 37, a pressure plate 38, and a first connecting rod. The first connecting rod 9 is fixedly connected to the top of the second rack 31. The second connecting rod 51 is fixedly installed on the first connecting rod and is located outside the water storage tank 43. The pressure plate 38 is fixedly installed on the second connecting rod 51. The self-resetting switch 37 is fixedly installed on the expansion plate 8 and is located on one side of the water storage tank 43. The pressure plate 38 is located directly above the self-resetting switch 37. Several heating sources 36 are installed on the isolation box 2, and the self-resetting switch 37 is electrically connected to the heating source 36. The rear of the workbench 1 is provided with a hinged door 52 for easy access to workpieces. It also includes a pressure valve 53, which is fixed on the transmission pipe 34 and located below the pressure plate 38.

[0020] When the grinding tool 20 needs to be adjusted in terms of its forward / backward and left / right positions, the operator starts the second motor 10. The second motor 10 drives the second rotating shaft 12 to rotate, which in turn moves the first guide block 13. This movement of the first guide block 13 then drives the third motor 14 to move, thus enabling the grinding tool 20 to move forward / backward. Next, the operator starts the third motor 14, which drives the third rotating shaft 16 to rotate. This movement of the third rotating shaft 16 then moves the second guide block 17 left / right. The second guide block 17 then drives the fourth motor 18, the fourth rotating shaft 19, and the grinding tool 20 to rotate, thus enabling the grinding tool 20 to move left / right. When machining a workpiece, the operator starts the fourth motor 18, which drives the fourth rotating shaft 19 to rotate. The fourth rotating shaft 19 drives the grinding cutter 20 to rotate, and the grinding cutter 20 begins to machine the workpiece held in the clamping slot. In this way, the workpiece is ground in all directions. After machining is completed, the operator turns off the fourth motor 18, then opens the door 52 at the rear of the worktable 1, and then rotates the bolt 47 to remove the workpiece held in the clamping seat 46. Then the door 52 is closed. At this time, the operator begins the push-back process. First, the second motor 10 is started, which drives the second rotating shaft 12 to rotate. The second rotating shaft 12 drives the first guide block 13 to move. The first guide block 13 moves while also... The fourth motor 18 moves back and forth, causing the pressing rod 26 to move within the second elongated groove 44 and the third elongated groove 45 of the crossbar 27 until the first guide block 13 is returned to its original position. Then, the third motor 14 is activated, causing the third rotating shaft 16 to rotate. The third rotating shaft 16 then moves the second guide block 17 back to its original position. The second guide block 17 then moves the fourth motor 18 back to its original position, and the fourth motor 18 moves the pressing rod 26 left and right. The pressing rod 26 presses against the crossbar 27, causing the first rack 30 to move left and right. The first rack 30 then drives the first gear 32 to rotate, which in turn drives the rotating shaft 28 to rotate. The rotating shaft 28 then drives the second gear to rotate. The second rack 31 rotates, causing the first connecting rod 9 and the second connecting rod 51 to move vertically in opposite directions. The second connecting rod 51 causes the pressure plate 38 to press against the self-resetting switch 37 on the expansion plate 8 and the pressure valve 53 on the transmission pipe 34. At this time, the pressure valve 53 releases, spraying the clean water in the water tank 43 out from the spray ball head 33. The water pipe of the transmission pipe 34 is located on one side of the water tank 43 and turns to the rear of the workbench 1 until it is connected to the spray ball head 33. At the same time, the pressure plate 38 presses against the self-resetting switch 37. Since the clean water in the water tank 43 is drained, the cutting fluid splashed in the isolation box 2 and the groove 3 of the workbench 1 is diluted and finally heated by the heating source 36 located on the isolation box 2.The purified water and the mixture of purified water and cutting fluid located in isolation chamber 2 are desalinated and dried to reduce corrosion of the internal components of the grinding machine.

[0021] like Figure 1 As shown, it also includes a water pump 39, a circulation pipe 40, and a filter screen 41. The two ends of the circulation pipe 40 are respectively connected to the bottom of the workbench 1 and the coolant tank 21. The filter screen 41 is located in the circulation pipe 40 near the side of the workbench 1. After the previous complete workflow is completed, the mixture of clean water and cutting fluid flows to the bottom of the workbench 1 and into the circulation pipe 40. Because the cutting fluid can be reused, it can be diluted with clean water and reused. The filter screen 41 isolates the iron wire or waste chips processed by the grinding tool 20. It also includes a slide rail 54, a moving plate 55, and a sliding groove 50. The slide rail 54 is laid longitudinally in the through hole 49. The moving plate 55 is slidably mounted on the slide rail 54, and the moving plate 55 has a sliding groove 50. The first rack 30 is slidably mounted in the sliding groove 50. Through the slide rail 54 and the sliding groove 50 on the moving plate 55, the grinding tool 20 can move the first rack 30 in the same direction during the retraction process.

[0022] Working principle:

[0023] When it is necessary to remove the finished isolation box 2 and cutting fluid, the operator first places the workpiece into the clamping slot in the clamping seat 46. Then, the operator rotates the bolt 47, which moves the clamping plate 48 within the clamping slot until the clamping plate 48 secures the workpiece. Next, the operator starts the first motor 6, which drives the first rotating shaft 7 to rotate. The first rotating shaft 7 moves the work plate 5 back and forth, causing the workpiece on the clamping assembly to move. Then, the operator starts the second translation assembly, which moves the third translation assembly and the grinding assembly to the appropriate position. At this point, the third translation assembly is started, moving the grinding assembly to the position to be processed. While the workpiece is being processed, the grinding assembly is simultaneously activated. During the processing, the operator activates the liquid spraying assembly, which sprays cutting fluid to cool the cutting tool of the grinding assembly. During this cooling process, the cutting fluid splashes into the isolation chamber 2 and the worktable 1. Once the workpiece is finished, it is removed from the clamping assembly. When the cutting tool on the grinding assembly needs to be returned to its original position and the grinding tool 20 needs to be adjusted in both forward / backward and left / right positions, the operator activates the second motor 10. The second motor 10 drives the second rotating shaft 12 to rotate, which in turn moves the first guide block 13. This movement of the first guide block 13 then drives the third motor 14 to move... The movement of the first guide block 13, which drives the grinding tool 20, allows it to move back and forth. Then, the operator starts the third motor 14, which drives the third rotating shaft 16 to rotate. The third rotating shaft 16 drives the second guide block 17 to move left and right. The second guide block 17 drives the fourth motor 18, the fourth rotating shaft 19, and the grinding tool 20 to rotate, thus enabling the second guide block 17 to drive the grinding tool 20 to move left and right. When starting to process the workpiece, the operator starts the fourth motor 18, which drives the fourth rotating shaft 19 to rotate. The fourth rotating shaft 19 drives the grinding tool 20 to rotate, and the grinding tool 20 begins to process the workpiece held in the clamping slot. In this way, the workpiece is ground in all directions (back, front, left, and right). When processing is complete... Afterwards, the operator shuts off the fourth motor 18, opens the hatch 52 at the rear of the worktable 1, rotates the bolt 47 to remove the workpiece clamped on the clamping seat 46, and then closes the hatch 52. At this point, the operator begins the pushing process, first starting the second motor 10. The second motor 10 drives the second rotating shaft 12 to rotate, and the second rotating shaft 12 drives the first guide block 13 to move. As the first guide block 13 moves, it also drives the fourth motor 18 to move back and forth. At this time, the fourth motor 18 drives the pressing rod 26 to move within the second elongated groove 44 and the third elongated groove 45 in the crossbar 27 until the first guide block 13 is returned to its position. Then, the third motor 14 is started, and the third motor 14 drives the third rotating shaft 16 to rotate.The third rotating shaft 16 drives the second guide block 17 to return to its original position. At this time, the second guide block 17 drives the fourth motor 18 to return to its original position. The fourth motor 18 drives the extrusion rod 26 to move left and right. At this time, the extrusion rod 26 extrudes the crossbar 27. The crossbar 27 drives the first rack 30 to move left and right. At this time, the first rack 30 drives the first gear 32 to rotate. The first gear 32 drives the rotating shaft 28 to rotate. The rotating shaft 28 drives the second gear to rotate. The second gear drives the second rack 31 to rotate. The second rack 31 drives the first connecting rod 9 and the second connecting rod 51 to move vertically in opposite directions. The second connecting rod 51 drives the pressure plate 38 to press against the self-resetting switch 37 on the expansion plate 8 and the pressure valve 53 on the transmission pipe 34. At this time, the pressure valve 53 releases, and the clean water in the water tank 43 is sprayed out from the spray ball head 33. The water pipe of the transmission pipe 34 is located on one side of the water tank 43. The transmission pipe 34 turns to the rear of the worktable 1 until it connects with the spray ball head 33, and the pressure plate 38 simultaneously presses against the self-reset switch 37. At this time, after the clean water in the water tank 43 is drained, the cutting fluid splashed in the isolation box 2 and the groove 3 of the worktable 1 is diluted. Finally, it is heated by the heating source 36 located on the isolation box 2 to dilute and dry the clean water and the mixture of clean water and cutting fluid in the isolation box 2, reducing corrosion to the internal machinery of the grinding machine. This method protects the maintenance of the grinding machine and improves the work efficiency of the operator. It also avoids the step of the operator having to put their body part into the grinding machine to wipe off the cutting fluid after the workpiece is finished. This method also reduces the need for the operator to repeatedly wipe the cutting fluid inside the grinding machine after the workpiece is finished, reducing a lot of manpower and material resources.

[0024] After the previous complete workflow is completed, the mixture of clean water and cutting fluid flows to the bottom of the workbench 1 and into the circulation pipe 40. Because the cutting fluid can be reused, it can be diluted with clean water and reused. The filter screen 41 isolates the iron wire or waste chips processed by the grinding tool 20. In this way, the iron wire and cutting fluid can be isolated. The system also includes a slide rail 54, a moving plate 55 and a sliding groove 50. The slide rail 54 is laid in the through hole 49 along the width direction of the isolation box 2. The moving plate 55 is slidably installed on the slide rail 54 and has a sliding groove 50. The first rack 30 is slidably installed in the sliding groove 50. The slide rail 54 and the sliding groove 50 on the moving plate 55 enable the grinding tool 20 to move in the same direction as the first rack 30 during the retraction process.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
