Description

Technical Field

[0001] This utility model belongs to the field of cemented carbide processing technology, specifically relating to a cemented carbide CNC grinding equipment that facilitates tool head replacement. Background Technology

[0002] Hard alloy is an alloy material made by powder metallurgy of hard compounds of refractory metals and binder metals.

[0003] Hard alloys possess a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, their high hardness and wear resistance remain essentially unchanged even at 500℃, and they still have very high hardness at 1000℃.

[0004] Carbide is widely used as a cutting tool material, such as turning tools, milling cutters, planing tools, drills, boring tools, etc. It is used to cut cast iron, non-ferrous metals, plastics, chemical 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.

[0005] In the production and processing of cemented carbide, a variety of processing equipment is required, one of which is grinding equipment. Grinding equipment is used to grind alloy workpieces. However, the cutting heads on existing grinding equipment are all threaded. During the grinding process, the threads of the cutting head are prone to breakage, which can lead to the cutting head getting stuck and difficult to disassemble. Therefore, we propose a cemented carbide grinding equipment that facilitates the replacement of cutting heads. Utility Model Content

[0006] The purpose of this utility model is to provide a CNC grinding equipment for carbide that facilitates the replacement of cutting heads, in order to solve the problem mentioned in the background art that the cutting heads on existing grinding equipment are all installed by thread, and the thread of the cutting head is easily damaged during the grinding process, which will lead to the cutting head getting stuck and difficult to disassemble.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a CNC grinding machine for easy tool replacement of cemented carbide, comprising a base plate, a cylinder one and a machining frame mounted on the upper surface of the base plate, a fixed frame fixedly mounted on the piston rod end of the cylinder one, and a plurality of fixing screws threaded onto the fixed frame, a cylinder two fixedly mounted on the side of the machining frame, a sliding plate fixedly mounted on the piston rod end of the cylinder two, a sliding seat slidably disposed on the side of the sliding plate, limit tracks are provided on both the upper and lower sides of the machining frame, and limit blocks are slidably mounted within the limit tracks, a motor one fixedly mounted on the surface of one of the limit blocks, and a screw rotatably mounted between the two limit blocks. The threaded rod is fixedly connected to one end of the output shaft of motor one. A sliding seat is threaded onto the outer surface of the threaded rod. A mounting seat is fixedly mounted on the side of the sliding seat. Motor two is fixedly mounted on the side of the mounting seat. A rotating seat is fixedly mounted on the end of the output shaft of motor two. A rotating shaft is rotatably mounted on the rotating seat. A tool holder is fixedly mounted on the outer surface of the rotating shaft. A tool head is provided on one side of the tool holder. A insertion post is fixedly mounted on one end of the tool head. A groove for inserting the insertion post is opened on the side of the tool holder. An operating pull plate is slidably mounted on the tool holder. An insertion rod is fixedly mounted on the surface of the operating pull plate. The insertion rod is slidably mounted on the tool holder. A rod groove for inserting the insertion rod is opened on the insertion post.

[0008] The above scheme uses a plunger inserted into a groove and a rod inserted into a groove to achieve stable locking of the cutting head. Compared with threaded connections, this prevents the cutting head from getting stuck and difficult to disassemble due to thread breakage. The structure is simple and facilitates the disassembly and replacement of the cutting head. A second cylinder works with a sliding plate to achieve horizontal movement of the sliding seat, which in turn achieves horizontal movement of the cutting head. A first motor works with a threaded rod to achieve vertical movement of the sliding seat, which in turn achieves vertical movement of the cutting head. A rotating shaft is used to adjust the angle of the cutting head, making it suitable for grinding operations at different positions and angles.

[0009] In the above scheme, it should be noted that cylinder one, cylinder two, motor one and motor two are all electrically connected to an external power supply.

[0010] In a preferred embodiment, a plurality of sliding guide rods are slidably mounted on the side of the processing card frame, and one end of each sliding guide rod is fixedly connected to the side of the sliding plate.

[0011] By adopting the above scheme, the movement of the sliding plate can be guided by the sliding guide rod, so that the sliding plate can move stably under the drive of the cylinder.

[0012] In a preferred embodiment, the sliding plate has a trapezoidal groove on its side, and the sliding seat has a trapezoidal slider fixedly installed on its side, with the trapezoidal slider slidably installed on the inner wall of the trapezoidal groove.

[0013] By adopting the above scheme, the sliding block can slide in the trapezoidal groove, which can ensure that the up and down movement of the sliding seat is stable, and can also ensure that the sliding plate can drive the sliding seat to move synchronously when it moves.

[0014] In a preferred embodiment, a fixing guide rod is fixedly installed on the inner wall of the upper limit channel of the processing card frame, and the limiting block is slidably installed on the outer surface of the fixing guide rod at the same position.

[0015] By adopting the above scheme, the setting of the fixed guide rod one plays a role in limiting and guiding the limit block, making the movement of the limit block more stable.

[0016] In a preferred embodiment, a plurality of fixed guide rods are fixedly installed between the two limiting blocks, and the sliding seat is slidably installed on the outer surface of the plurality of fixed guide rods.

[0017] Using the above scheme, when the screw rod rotates and drives the sliding seat to move up and down, the sliding seat will slide on the surface of the fixed guide rod two. Therefore, the setting of the fixed guide rod two can ensure the smooth movement of the sliding seat.

[0018] In a preferred embodiment, an adjusting rod is fixedly mounted on the surface of the tool holder, and an arc-shaped slide is provided on the rotating seat. The adjusting rod passes through the arc-shaped slide, and the surface of the adjusting rod has threads on which an adjusting nut is threaded and installed. The adjusting nut is fitted and positioned on the surface of the rotating seat.

[0019] Using the above scheme, the adjusting rod is used in conjunction with the arc-shaped slide and the adjusting nut. When the adjusting nut is unscrewed, the tool holder is unlocked. At this time, the tool holder can be rotated through the rotating shaft. After rotating, tightening the adjusting nut can achieve position compression locking, thereby realizing the angle adjustment of the tool head.

[0020] In a preferred embodiment, a guide block is fixedly installed on the side of the tool holder, a guide rod is slidably installed on the guide block, one end of the guide rod is fixedly connected to the operating pull plate, a limit plate is fixedly installed on the other end of the guide rod, and a spring is fixedly installed between the limit plate and the guide block.

[0021] By adopting the above scheme, the guide block and guide rod work together to ensure the stable movement of the operating plate and avoid deviation. The setting of the limit plate can prevent the guide rod from slipping off the guide block. The spring force can drive the insertion rod to quickly insert into the rod groove, improving the convenience of locking operation.

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

[0023] This carbide CNC grinding equipment, which facilitates tool head replacement, uses a plunger inserted into a groove and a rod inserted into a groove to achieve stable locking of the tool head. Compared with threaded connections, it can prevent tool head jamming and difficulty in disassembly caused by thread breakage. The structure is simple and facilitates tool head disassembly and replacement.

[0024] This carbide CNC grinding machine, which facilitates tool head replacement, uses a cylinder two in conjunction with a sliding plate to achieve horizontal movement of the sliding seat, thereby achieving horizontal movement of the tool head. A motor one in conjunction with a threaded rod achieves vertical movement of the sliding seat, thereby achieving vertical movement of the tool head.

[0033] By inserting the insert post 18 into the post groove and using the insert rod 24 into the rod groove, the cutter head 17 is stably locked. Compared with threaded connection, this can prevent the cutter head 17 from getting stuck and difficult to disassemble due to thread breakage. The structure is simple and easy to disassemble and replace the cutter head 17. The cylinder 2 6 is used in conjunction with the sliding plate 7 to realize the horizontal movement of the sliding seat 8, thereby realizing the horizontal movement of the cutter head 17. The motor 10 is used in conjunction with the threaded rod 11 to realize the vertical movement of the sliding seat 8, thereby realizing the vertical movement of the cutter head 17. The rotating shaft 15 is used to realize the angle adjustment of the cutter head 17, which is suitable for grinding operations at different positions and angles.

[0034] Several sliding guide rods 19 are slidably installed on the side of the processing frame 4. One end of the sliding guide rod 19 is fixedly connected to the side of the sliding plate 7.

One end of the guide rod 26 is fixedly connected to the operating pull plate 23, and a limit plate 27 is fixedly installed on the other end of the guide rod 26. A spring 28 is fixedly installed between the limit plate 27 and the guide block 25. The guide block 25 and the guide rod 26 work together to ensure the stable movement of the operating pull plate 23 and avoid deviation. The limit plate 27 can prevent the guide rod 26 from detaching from the guide block 25 when sliding. The elastic force of the spring 28 can drive the insertion rod 24 to quickly insert into the rod groove, improving the convenience of locking operation.

[0040] In use, place the alloy workpiece to be ground in the fixed frame 3, and tighten the fixing screws 5 to secure the workpiece. Check if the cutter head 17 needs to be replaced. If so, pull the operating plate 23. The movement of the operating plate 23 drives the insertion rod 24 to move, causing the insertion rod 24 to disengage from the rod groove. At this time, the insertion post 18 is unlocked and the cutter head 17 can be removed. Insert the new cutter head 17 into the groove through the insertion post 18. Release the operating plate 23. At this time, the insertion rod 24 will be inserted into the rod groove under the action of the spring 28, locking the cutter head 17. Then, start the cylinder 6 to drive the sliding plate 7 to move the sliding seat 8 horizontally, thereby moving the cutter head 17 horizontally. The position is adjusted by moving the cylinder 6, then stopping the cylinder and starting the motor 10. The motor 10 drives the threaded rod 11 to rotate, which in turn drives the sliding seat 8 to move up and down, thereby driving the cutter head 17 to move up and down to adjust its position. Then, the adjusting nut 30 is unscrewed, at which point the cutter holder 16 is unlocked. The shaft 15 drives the cutter holder 16 to rotate the cutter head 17. After adjusting to the appropriate angle, the adjusting nut 30 is screwed on to lock the position. Then, the motor 13 is started to drive the rotating seat 14 to rotate, which in turn drives the cutter head 17 to rotate through the cutter holder 16. At the same time, the cylinder 2 is started, which drives the fixed frame 3 to move the alloy workpiece to be ground toward the cutter head 17 to achieve grinding.
