Description

Technical Field

[0001] This utility model belongs to the field of grinding technology, specifically relating to a carbide CNC grinding machine that is easy to adjust. Background Technology

[0002] Carbide is widely used as a cutting tool material, such as turning tools, milling cutters, planing tools, drills, and boring tools, for cutting cast iron, non-ferrous metals, plastics, synthetic fibers, graphite, glass, stone, and ordinary steel. It can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, high-manganese steel, and tool steel. Various mechanical equipment is required in the machining of carbide, one of which is the CNC grinding machine. CNC grinding machines are machine tools that use CNC technology to grind the surface of workpieces using grinding wheels. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other grinding wheels and free abrasives such as oilstones, abrasive belts, honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines. CNC grinding machines include CNC surface grinders, CNC centerless grinders, CNC internal and external cylindrical grinders, CNC vertical universal grinders, CNC coordinate grinders, and CNC profile grinders, among others.

[0003] On existing CNC grinding machines, the clamping plates for holding and fixing alloy workpieces are of a fixed shape. That is, flat clamping plates are required for alloy workpieces with flat surfaces, and curved clamping plates are required for alloy workpieces with curved surfaces. Flat clamping plates and curved clamping plates need to be repeatedly disassembled, installed and replaced, which is inconvenient and reduces work efficiency. In addition, the chips generated during the grinding process are easy to accumulate and disperse inside the grinding machine, which will affect the normal operation. Utility Model Content

[0004] The purpose of this invention is to provide an easily adjustable CNC grinding machine for cemented carbide, to solve the problem mentioned in the background art that the clamping and fixing of alloy workpieces on existing CNC grinding machines is of a fixed shape. That is, for alloy workpieces with flat surfaces, a flat clamping plate needs to be installed, and for alloy workpieces with curved surfaces, a curved clamping plate needs to be installed. The flat clamping plate and the curved clamping plate need to be repeatedly disassembled and installed, which is inconvenient to operate, reduces work efficiency, and the chips generated during the grinding process are easy to accumulate and disperse inside the grinding machine, thus affecting the normal operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable carbide CNC grinding machine, comprising a grinding machine body, a support platform movably disposed inside the grinding machine body, a motor fixedly mounted on the side of the support platform, a bidirectional screw rotatably mounted inside the support platform, the output shaft of the motor being fixedly connected to one end of the bidirectional screw, threaded plates threaded onto the outer surfaces of both ends of the bidirectional screw, a push rod fixedly mounted on the side of the threaded plate, the push rod slidingly extending through the support platform and fixedly mounted with a push frame, and so on. An adjusting plate is slidably mounted on the push frame. A support plate is fixedly installed at one end of the adjusting plate. A rotating shaft is rotatably mounted on the surface of the support plate. An mounting plate is fixedly installed at the top of the rotating shaft. An arc-shaped clamping plate and a flat clamping plate are fixedly installed on opposite sides of the mounting plate, respectively. A collection box is fixedly installed on the side of the grinding machine body. An exhaust fan is fixedly installed on the upper surface of the collection box. The exhaust fan's outlet extends into the inside of the collection box. The exhaust fan's inlet extends into the inside of the grinding machine body and is fixedly fitted with a dust extraction hood. A filter screen is detachably installed on the side of the collection box.

[0006] The above solution utilizes a support platform in conjunction with flat and curved clamping plates. These plates are positioned opposite each other and their positions can be interchanged via a rotating shaft. This allows for the selection of either a suitable flat or curved clamping plate based on the surface shape of the alloy workpiece. Furthermore, an adjustment plate can slide on the push frame to adjust the initial position of the flat or curved clamping plate, significantly expanding its applicability. A collection box, along with an exhaust fan and filter, extracts and transports debris generated during the grinding process to the collection box. The debris is then filtered through the filter, preventing it from accumulating and scattering, thus ensuring smooth operation. The filter is also easily removable and hygienic for cleaning.

[0007] In the above scheme, it should be noted that the motor is electrically connected to an external power supply.

[0008] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the bearing platform, and the end of the threaded plate is provided with a guide groove for cooperating with the guide bars.

[0009] Using the above scheme, when the threaded plate is driven to move during the rotation of the bidirectional screw, the threaded plate will slide on the surface of the guide bar through the guide groove. Therefore, the stable movement of the threaded plate can be ensured by the cooperation of the guide bar and the guide groove.

[0010] In a preferred embodiment, a limiting piece is fixedly installed at the other end of the adjusting plate.

[0011] By adopting the above solution, the setting of the limiting plate can play a limiting role, preventing the adjustment plate from detaching from the push frame when it slides for adjustment.

[0012] In a preferred embodiment, an adjusting rod is slidably mounted on the push frame, an adjusting plate is fixedly mounted on the top of the adjusting rod, a spring is fixedly mounted between the adjusting plate and the push frame, and a plurality of adjusting grooves are formed on the surface of the adjusting plate to cooperate with the adjusting rod.

[0013] Using the above solution, the adjusting rod is used in conjunction with spring one. When the adjusting rod is disengaged from the adjusting groove, the spring deforms, and the adjusting plate can slide to adjust the position. After adjustment, the elastic force of spring one drives the adjusting rod to quickly insert into the adjusting groove, improving the convenience of operation and adjustment.

[0014] In a preferred embodiment, two sliding columns are slidably mounted on the support plate. The two sliding columns are symmetrically arranged at 180 degrees with the axis of rotation as the axis. An operating plate and a locking plate are fixedly mounted at the bottom and top of the sliding columns, respectively. A spring is fixedly mounted between the locking plate and the support plate. Two locking grooves are formed on the lower surface of the mounting plate. The locking plate and the locking grooves are used in conjunction.

[0015] Using the above scheme, the sliding column is used in conjunction with spring two and the locking plate. When the locking plate is disengaged from the lock groove, the mounting plate is unlocked. At this time, spring two is deformed, and the flat plate and the curved plate can be rotated and swapped. After the swapping is completed, the elastic force of spring two is used to drive the locking plate to quickly insert into the lock groove, thereby improving the convenience of locking operation.

[0016] In a preferred embodiment, anti-slip pads are affixed to the sides of both the flat card plate and the curved card plate.

[0017] By adopting the above solution, the use of anti-slip pads can improve the fixing effect on alloy workpieces and prevent slippage during fixing.

[0018] In a preferred embodiment, a plurality of fixing blocks are fixedly installed on the side of the filter screen, and fixing bolts are threaded onto the fixing blocks. The side of the collection box is provided with a fixing thread groove for the fixing bolts to be screwed into.

[0019] By using the above solution, and by combining fixing blocks and fixing bolts, a stable installation of the filter screen can be achieved. The installation structure is simple and the operation is convenient.

[0020] In a preferred embodiment, a number of alignment blocks are fixedly installed on the side of the collection box, and a number of alignment holes are provided on the filter screen for the alignment blocks to be inserted.

[0021] By using the above solution, the alignment blocks and alignment holes can be used together to align and assemble the filter screen, improving the ease of assembly.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This easily adjustable carbide CNC grinding machine is equipped with a support table and uses a flat chuck and an arc chuck. The flat chuck and the arc chuck are set opposite each other and their positions can be changed by rotating the spindle. Thus, the appropriate flat chuck or arc chuck can be selected according to the surface shape of the carbide workpiece. The adjustment plate can slide on the push frame to adjust the position, thereby adjusting the initial position of the flat chuck or arc chuck, which greatly improves the applicability.

[0024] This easily adjustable carbide CNC grinding machine is equipped with a collection box that works in conjunction with an exhaust fan and a filter. During the operation of the grinding machine, the debris generated is drawn by the exhaust fan and transported to the collection box, where it is filtered by the filter to prevent debris from accumulating and scattering, thus avoiding disruption to normal operation. The filter can also be easily disassembled and cleaned. Attached Figure Description

[0034] Please see Figure 1-8 This utility model provides an easily adjustable carbide CNC grinding machine, including a grinding machine body 1. A support platform 2 is movably disposed inside the grinding machine body 1. A motor 3 is fixedly mounted on the side of the support platform 2. A bidirectional screw 4 is rotatably mounted inside the support platform 2. The output shaft of the motor 3 is fixedly connected to one end of the bidirectional screw 4. Threaded plates 5 are threaded onto the outer surfaces of both threads of the bidirectional screw 4. A push rod 6 is fixedly mounted on the side of the threaded plate 5. The push rod 6 slides through and extends out of the support platform 2 and is fixedly mounted on a push frame 7. An adjusting plate 8 is slidably disposed on the push frame 7. A support plate 9 is fixedly installed at one end of the section plate 8. A rotating shaft 10 is rotatably installed on the surface of the support plate 9. An mounting plate 11 is fixedly installed at the top of the rotating shaft 10. An arc-shaped clamping plate 12 and a flat clamping plate 13 are fixedly installed on opposite sides of the mounting plate 11, respectively. A collection box 14 is fixedly installed on the side of the grinding machine body 1. An exhaust fan 15 is fixedly installed on the upper surface of the collection box 14. The air outlet of the exhaust fan 15 extends into the inside of the collection box 14. The air inlet of the exhaust fan 15 extends into the inside of the grinding machine body 1 and is fixedly installed with a dust extraction hood 16. A filter screen 17 is detachably installed on the side of the collection box 14.

[0035] By setting up a support platform 2 in conjunction with a flat clamping plate 13 and an arc-shaped clamping plate 12, the flat clamping plate 13 and the arc-shaped clamping plate 12 are arranged opposite each other and their positions can be changed by rotating the rotating shaft 10. Thus, a suitable flat clamping plate 13 or arc-shaped clamping plate 12 can be selected according to the surface shape of the alloy workpiece. The adjusting plate 8 can slide and adjust its position on the push frame 7, thereby adjusting the initial position of the flat clamping plate 13 or the arc-shaped clamping plate 12, greatly improving the applicability. By setting up a collection box 14 in conjunction with an exhaust fan 15 and a filter screen 17, the debris generated during the operation of the grinding machine body 1 is extracted by the exhaust fan 15 and transported to the collection box 14. After being filtered by the filter screen 17, the debris is prevented from accumulating and scattering, which would affect the normal operation. The filter screen 17 can be easily disassembled and cleaned.

[0036] Several guide bars 18 are fixedly installed on the inner wall of the bearing platform 2. The end of the threaded plate 5 is provided with a guide groove that cooperates with the guide bars 18. When the threaded plate 5 is driven to move during the rotation of the bidirectional screw 4, the threaded plate 5 will slide on the surface of the guide bars 18 through the guide groove. Therefore, the stable movement of the threaded plate 5 can be ensured by the cooperation of the guide bars 18 and the guide groove.

[0037] A limiting piece 19 is fixedly installed at the other end of the adjusting plate 8. The limiting piece 19 can play a limiting role to prevent the adjusting plate 8 from detaching from the push frame 7 when it slides for adjustment.

[0038] An adjusting rod 20 is slidably mounted on the push frame 7. An adjusting pull plate 21 is fixedly mounted on the top of the adjusting rod 20. A spring 22 is fixedly mounted between the adjusting pull plate 21 and the push frame 7. Several adjusting grooves are opened on the surface of the adjusting plate 8 to cooperate with the adjusting rod 20. When the adjusting rod 20 is used in conjunction with the spring 22, the spring deforms when the adjusting rod 20 is disengaged from the adjusting groove. At this time, the adjusting plate 8 can slide to adjust the position. After adjustment, the elastic force of the spring 22 drives the adjusting rod 20 to quickly insert into the adjusting groove, improving the convenience of operation and adjustment.

[0039] Two sliding columns 23 are slidably mounted on the support plate 9. The two sliding columns 23 are symmetrically arranged at 180 degrees with the pivot 10 as the axis. An operating plate 24 and a locking plate 25 are fixedly mounted at the bottom and top of the sliding columns 23, respectively. A second spring 26 is fixedly mounted between the locking plate 25 and the support plate 9. Two locking grooves are opened on the lower surface of the mounting plate 11. The locking plate 25 and the locking grooves are used in conjunction. The sliding columns 23 are used in conjunction with the second spring 26 and the locking plate 25. When the locking plate 25 is disengaged from the locking groove, the mounting plate 11 is unlocked. At this time, the second spring 26 is deformed, and the flat plate 13 and the curved plate 12 can be rotated and swapped. After the swap, the elastic force of the second spring 26 drives the locking plate 25 to quickly insert into the locking groove, improving the convenience of locking operation.

[0040] Anti-slip pads 27 are attached to the sides of both the flat plate 13 and the curved plate 12. The anti-slip pads 27 can improve the fixing effect on the alloy workpiece and prevent slippage.

[0041] Several fixing blocks 28 are fixedly installed on the side of the filter screen 17. Fixing bolts 29 are threaded on the fixing blocks 28. The side of the collection box 14 has a fixing thread groove for the fixing bolts 29 to be screwed in. By using the fixing blocks 28 and fixing bolts 29 together, the filter screen 17 can be stably installed. The installation structure is simple and the operation is convenient.

[0042] Several alignment blocks 30 are fixedly installed on the side of the collection box 14. Several alignment holes are opened on the filter screen 17 for the alignment blocks 30 to be inserted. By using the alignment blocks 30 and the alignment holes together, the filter screen 17 can be aligned and assembled, improving the convenience of assembly operation.

[0043] In use, the initial position of the mounting plate 11 is adjusted according to the size of the alloy workpiece. During adjustment, pulling the adjusting plate 21 drives the adjusting rod 20 to move out of the adjusting groove. At this time, spring 22 deforms and the adjusting plate 8 unlocks. The adjusting plate 8 slides on the push frame 7 until it reaches the appropriate position. Then, the adjusting plate 21 is released, and the elastic force of spring 22 drives the adjusting rod 20 back into the adjusting groove, thus adjusting the initial position of the mounting plate 11. Next, the alloy workpiece is placed on the surface of the bearing platform 2. Depending on the surface shape of the alloy workpiece, either the curved clamping plate 12 or the flat clamping plate 13 is selected. During adjustment, pulling the operating plate 24 drives the sliding column 23 to move. The sliding column 23 drives the locking plate 25 to move out of the locking groove. At this time, spring 26 unlocks, and the mounting plate 11 unlocks. The mounting plate 11 can then be moved via the rotating shaft 10. The rotation causes the arc-shaped clamping plate 12 and the flat clamping plate 13 to rotate and flip to change their positions. After the position is changed, the operating plate 24 is released. At this time, the elastic force of the second spring 26 drives the locking plate 25 to move and engage in the locking groove to achieve locking. Then, the motor 3 is started to drive the bidirectional screw 4 to rotate, which in turn drives the threaded plate 5 to drive the push rod 6 to move. This drives the push frame 7, the adjusting plate 8, the support plate 9, and the mounting plate 11 to move the arc-shaped clamping plate 12 or the flat clamping plate 13 to achieve clamping of the alloy workpiece. Then, the motor 3 is stopped, and the grinding machine body 1 is started to perform grinding operations. The exhaust fan 15 is started to extract the debris generated during the grinding process. The debris is extracted and transported to the collection box 14 and filtered and collected by the filter screen 17. When it is necessary to clean the filter screen 17 and the collection box 14, the fixing bolt 29 is unscrewed. At this time, the filter screen 17 is unlocked and can be removed for cleaning.
