Description

Technical Field

[0001] The invention relates to the technical field of cylinder groove forming machines, in particular to a cylinder groove rapid forming machine. Background Art

[0002] Reference Figure 12 , is a schematic diagram of the cylinder structure of the compressor in this application. The compressor is provided with a through groove connected to the center hole on the cylinder. In the prior art, two devices are usually required to process the groove respectively for grooving and polishing.

[0003] However, cylinders produced using this method require transfer from the slotting equipment to the grinding equipment, a process that involves workpiece disassembly, transfer, and re-clamping and positioning. For batch production, this transfer time accumulates for each batch, significantly reducing output per unit time. Furthermore, during the second clamping process, the workpiece's positioning on the grinding equipment is difficult to completely align with the datum used during slotting, potentially causing deviations in the slot's positional accuracy. Summary of the Invention

[0004] In order to facilitate the processing and forming of the cylinder groove, the present application provides a cylinder groove rapid prototyping machine.

[0005] The present application provides a cylinder groove rapid prototyping machine that adopts the following technical solutions: A cylinder groove rapid prototyping machine includes a machine body, a clamp, a plurality of saw blades, a plurality of grinding heads, a switching mechanism and a driving mechanism. The machine body is respectively movably connected to a first seat and a second seat, the clamp is rotatably connected to the first seat, the switching mechanism includes a rotating seat and a plurality of driving rods, the rotating seat is rotatably connected to the first seat, a plurality of slide rails are provided on the rotating seat, a plurality of the driving rods respectively correspond to the plurality of slide rails, a plurality of the driving rods are respectively movably connected to the corresponding slide rails, and a plurality of the driving rods can be detached from the corresponding slide rails, a plurality of the saw blades and a plurality of grinding heads are respectively installed on the corresponding driving rods, and the driving mechanism is used to drive the rotation of the driving rods and the rotation of the rotating seat.

[0006] By adopting this technical solution, the fixture secures the workpiece, while the saw blade and grinding head can be used for cutting and grinding, respectively. A switching mechanism enables switching between the saw blade and grinding head to meet diverse processing needs. A drive mechanism provides power for switching and processing. The movable connection between the first and second seats allows for the adjustment of the positions of various components, facilitating the processing of cylinder slots of varying sizes and shapes. This improves the versatility and flexibility of the equipment and facilitates the processing and shaping of cylinder slots.

[0007] Preferably, the driving mechanism includes a solid plug rod, a hollow plug rod and a servo motor, the hollow plug rod is rotatably connected to the second seat, the solid plug rod is threadedly connected to the hollow plug rod, and the rotating seat is provided with a first plug groove that can be plugged into and matched with the solid plug rod. The servo motor is used to drive the rotation of the hollow plug rod. When the rotating seat needs to be driven to rotate, the servo motor drives the hollow plug rod to rotate in the opposite direction, so that the solid plug rod is extended to be plugged into and matched with the first plug groove.

[0008] By adopting this technical solution, a servo motor drives the hollow plunger, which is then engaged with the first slot on the swivel base to control its rotation. This structural design is simple and provides reliable transmission, enabling tool changes without the need for an additional motor. This provides stable power transmission for switching between saw blades and grinding heads, as well as for subsequent machining operations.

[0009] Preferably, several of the driving rods are respectively provided with a plug connector that can cooperate with the hollow plug rod, and the plug connector is provided with a second plug groove. When the driving rod needs to be driven to rotate, the plug connector cooperates with the hollow plug rod, and the solid plug rod moves to cooperate with the second plug groove. The rotation of the hollow plug rod drives the driving rod to rotate synchronously through the solid plug rod.

[0010] By adopting the above technical solution, the plug connector on the drive rod mates with the hollow plug rod, and the solid plug rod mates with the second plug slot on the plug connector, enabling the drive rod to rotate. This design enables the drive mechanism to accurately drive the rotating seat and the drive rod separately, facilitating the rotation of the rotating seat during different processing stages, such as when switching tools, and rotating the drive rod to rotate the saw blade or grinding head during processing, ensuring smooth processing.

[0011] Preferably, a limit member is also included, which is used to limit the rotation of the rotating seat. The limit member includes a limit column, a position sensor and a number of signal devices. A number of limit slots are opened on the circumferential side of the rotating seat, and the number of signal devices respectively corresponds to the number of limit slots. The first seat is rotatably connected to a turntable, and the rotating seat drives the turntable to rotate. The limit column is slidably connected to the turntable, and the position sensor is installed on the limit column. When the turntable rotates one circle, the limit column cooperates with different limit slots, and the position sensor abuts against the corresponding signal device. When the position sensor abuts against the specified signal device, the position sensor transmits a signal to the servo motor to stop the servo motor from rotating.

[0012] By adopting the above technical solution, the number of rotations and position of the rotating base can be precisely controlled through the coordination of the limit post, position sensor, and signal indicator. When the rotating base drives the turntable to the specified position, the position sensor contacts the corresponding signal indicator, causing the servo motor to stop, ensuring that the rotating base stops accurately at the required position, ensuring that the saw blade or grinding head can be accurately switched to the working position, and improving the processing accuracy and reliability.

[0013] Preferably, the turntable is provided with a first gear, the rotating seat is provided with a second gear, and the first gear and the second gear are meshed and connected.

[0014] By adopting the above technical solution, the turntable can accurately follow the rotation of the rotating seat, thereby ensuring that the limit column can accurately cooperate with the limit slot, and the position sensor can accurately abut the signal device, further improving the accuracy of the rotating seat rotation angle control.

[0015] Preferably, a limit assembly is also included, which is used to limit the position of the saw blade and the grinding head on the rotating seat. The limit assembly includes an arc-shaped rotating block, a limit block and an elastic sheet. A limit slot is provided in the slide rail, and the driving rod drives the saw blade or the grinding head to be slidably connected in the slide rail. The arc-shaped rotating block is rotatably connected in the limit slot, and the limit block is fixedly connected to the arc-shaped rotating block. The elastic sheet is bent in an arc shape, and the two ends of the elastic sheet in the bending direction are respectively fixedly connected in the limit slot. When the arc-shaped rotating block rotates to either side to the limit position, the limit block moves between the elastic sheet and the side wall of the limit slot on the other side.

[0016] By adopting the above technical solution, the combination of the arc-shaped rotating block, the limit block and the elastic sheet can prevent the saw blade and the grinding head from excessive movement or shaking in the slide rail, ensuring that they maintain a stable position on the rotating seat, which helps to improve processing accuracy, while also protecting the saw blade and the grinding head and extending their service life.

[0017] Preferably, the clamp includes a mounting seat, a positioning plate and a clamping block, the mounting seat is rotatably connected to the first seat, the positioning plate is fixedly connected to the mounting seat, a first avoidance groove for the tool to pass through is provided on the positioning plate, a second avoidance groove for the driving rod to move is provided on the positioning plate, the clamping block is movably connected to the positioning plate, a third avoidance groove for the tool to pass through is provided on the clamping block, and the first avoidance groove and the third avoidance groove are arranged opposite to the slide rail on one side of the clamp.

[0018] By adopting the above technical solution, the design of the mounting base, positioning plate, and clamping block facilitates workpiece positioning and clamping. The first and third clearance grooves are positioned directly opposite the slide rail, allowing the tool to directly contact the target position on the workpiece, improving machining accuracy. The second clearance groove provides ample space for the saw blade and grinding head to operate, preventing interference between the tool and the fixture, ensuring smooth machining and improving machining accuracy and quality.

[0019] The technical effects of the present invention are mainly reflected in the following aspects: 1. The fixture of the present invention is used to secure a workpiece. The saw blade and grinding head can be used for cutting and grinding, respectively. A switching mechanism enables switching between the saw blade and grinding head to meet different processing requirements. The drive mechanism provides power for switching and processing. The movable connection between the first and second seats allows the position of each component to be adjusted, facilitating the processing of cylinder slots of different sizes and shapes. This improves the versatility and flexibility of the equipment and facilitates the processing and shaping of cylinder slots. 2. The present invention uses a servo motor to drive a hollow plunger, which is then engaged with a solid plunger in a first slot on the swivel base to control the swivel base's rotation. This structural design is simple and reliable, and tool changes can be completed without an additional motor. This reduces the number of motors and spindle boxes required for tool changes, thus reducing the production budget of the grinder and providing stable power transmission for switching between saw blades and grinding heads, as well as subsequent processing operations. 3. The plug connector on the drive rod of the present invention mates with the hollow plug rod, while the solid plug rod mates with the second plug slot on the plug connector, enabling rotation of the drive rod. This design enables the drive mechanism to precisely drive the rotating seat and drive rod separately, facilitating rotation of the rotating seat during different processing stages, such as when switching tools, and rotating the drive rod to drive the saw blade or grinding head during processing, ensuring smooth processing.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-12 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0034] The embodiment of the present application discloses a cylinder groove rapid prototyping machine.

[0035] Reference Figure 1A cylinder groove rapid prototyping machine of this embodiment includes a body 1, a clamp 2, a saw blade 3, a grinding head 4, a switching mechanism 5 and a driving mechanism 6. A first seat 7 and a second seat 8 are movably connected to the body 1, and the first seat 7 slides in a horizontal direction, and the second seat 8 slides in a moving direction perpendicular to the first seat 7. The first seat 7 and the second seat 8 are respectively controlled to move by a combination of a lead screw and a motor.

[0036] Reference Figure 1 and Figure 2 The clamp 2 is rotatably connected to the first seat 7. The switching mechanism 5 includes a rotating seat 9 and two driving rods 37. The rotating seat 9 is rotatably connected to the first seat 7. Two slide rails 10 are provided on the rotating seat 9. The two slide rails 10 are evenly distributed on the circumferential side of the rotating seat 9. The two driving rods 37 correspond to the two slide rails 10 respectively. The two driving rods 37 are movably connected to the corresponding slide rails 10 respectively, and the two driving rods 37 can be moved away from the corresponding slide rails 10. The saw blade 3 and the grinding head 4 are respectively installed on the corresponding driving rods 37. The driving mechanism 6 is used to drive the rotation of the driving rod 37 and the rotation of the rotating seat 9.

[0037] Reference Figure 1 The fixture 2 is used to secure the workpiece. The saw blade 3 and grinding head 4 can be used for cutting and grinding, respectively. The switching mechanism 5 enables switching between the saw blade 3 and grinding head 4 to meet different processing requirements. The drive mechanism 6 provides power for switching and processing. The movable connection between the first seat 7 and the second seat 8 allows the position of each component to be adjusted, facilitating the processing of cylinder 20 slots of different sizes and shapes. This improves the versatility and flexibility of the equipment and facilitates the processing and forming of cylinder 20 slots.

[0038] Reference Figure 6 、 Figure 8 and Figure 9 The driving mechanism 6 includes a solid plug rod 11, a hollow plug rod 12 and a servo motor 13. The hollow plug rod 12 is rotatably connected to the second seat 8. A plurality of threads are provided in the hollow plug rod 12, that is, a plurality of spiral slideways 42 are evenly distributed around the circumferential inner wall of the hollow plug rod 12. A plurality of sliding heads 43 are fixedly connected to one end of the axial direction of the solid plug rod 11. The plurality of sliding heads 43 correspond to the plurality of spiral slideways 42 respectively. The plurality of sliding heads 43 are respectively slidably connected in the plurality of spiral slideways 42, so that the solid plug rod 11 is threadedly connected to the hollow plug rod 12, and a plug block 41 with a counterweight effect is fixedly connected to the end of the solid plug rod 11 away from the hollow plug rod 12. A first plug slot 15 is provided on the rotating seat 9, which can be plugged into and matched with the plug block 41 on the solid plug rod 11. The servo motor 13 is used to drive the rotation of the hollow plug rod 12. When the rotating seat 9 needs to be driven to rotate, the servo motor 13 drives the hollow plug rod 12 to rotate in the opposite direction, so that the solid plug rod 11 is extended to make the plug block 41 plug into and match with the first plug slot 15.

[0039] Reference Figure 7 and Figure 10 The servo motor 13 reversely drives the hollow plunger 12, utilizing centrifugal force to extend the solid plunger 11 and engage with the first insertion slot 15 on the rotating seat 9, thereby controlling the rotation of the rotating seat 9. Reverse rotation causes the solid plunger 11 to retract into the hollow plunger 12 when not in operation. This structural design is simple and reliable, and tool changing can be completed without an additional motor. This can reduce the number of motors and spindle boxes used for tool changing, thereby reducing the production budget of the grinding machine. It also provides stable power transmission for switching between the saw blade 3 and the grinding head 4 and subsequent processing operations.

[0040] Reference Figure 2 and Figure 3 The two drive rods 37 are each fixedly connected to a plug connector 16 that can mate with the hollow plug rod 12. The plug connector 16 is provided with a second plug slot 17 that can mate with the plug block 41 on the solid plug rod 11. When the drive rod 37 needs to be driven to rotate, the plug connector 16 mates with the hollow plug rod 12, and the plug block 41 on the solid plug rod 11 mates with the second plug slot 17. The plug connector 16 on the drive rod 37 mates with the hollow plug rod 12, and the solid plug rod 11 mates with the second plug slot 17 on the plug connector 16, thereby realizing the rotation of the drive rod 37. This design enables the drive mechanism 6 to accurately drive the rotating base 9 and the drive rod 37 separately, facilitating the rotation of the rotating base 9 during different processing stages, such as when switching tools, and rotating the drive rod 37 during the processing to drive the saw blade 3 or the grinding head 4 to rotate, ensuring smooth processing.

[0041] Reference Figure 6 and Figure 7 The hollow plug rod 12 is provided with an air hole 38, and a vacuum pump is installed on the body 1. The air hole 38 is connected to the vacuum pump. When the plug connector 16 is matched with the hollow plug rod 12 and the solid plug rod 11 is matched with the second plug slot 17, the vacuum pump vacuums the hollow plug rod 12, so that the driving rod 37 is adsorbed on the hollow plug rod 12 by air pressure, reducing the possibility of the driving rod 37 falling off.

[0042] Reference Figure 2 、 Figure 3 and Figure 5, also includes a limit member 18, the limit member 18 is used to limit the rotation of the rotating seat 9, the limit member 18 includes a limit column 19, a position sensor 40 and two signal devices 39, two limit slots 22 are provided on the circumferential side of the rotating seat 9, the two signal devices 39 correspond to the two limit slots 22 respectively, the first seat 7 is rotatably connected to the turntable 23, the rotating seat 9 can drive the turntable 23 to rotate, that is, the turntable 23 is coaxially and fixedly connected with a first gear 24, the rotating seat 9 is coaxially and fixedly connected with a second gear 25, and the first gear 24 and the second gear 25 are meshed and connected. The limit column 19 is slidably connected to the turntable 23 along a direction perpendicular to the rotation direction of the turntable 23. The position sensor 40 is installed on the limit column 19. When the turntable 23 rotates one circle, the limit column 19 cooperates with different limit slots 22, and the position sensor 40 abuts against the corresponding signal device 39. When the position sensor 40 abuts against the designated signal device 39, the position sensor 40 transmits a signal to the servo motor 13, causing the servo motor 13 to stop rotating.

[0043] Reference Figure 2 、 Figure 3 and Figure 5 The coordination of the limit post 19, the position sensor 40, and the signal indicator 39 allows for precise control of the number of revolutions and position of the rotating base 9. When the rotating base 9 drives the turntable 23 to a desired position, the position sensor 40 contacts the corresponding signal indicator 39, causing the servo motor 13 to stop, ensuring that the rotating base 9 stops precisely at the desired position and that the saw blade 3 or grinding head 4 can be accurately switched to the working position, thereby improving machining accuracy and reliability.

[0044] Reference Figure 3 and Figure 4 , also includes a limit assembly 26, which is used to limit the position of the saw blade 3 and the grinding head 4 on the rotating seat 9. The limit assembly 26 includes an arc-shaped rotating block 27, a limit block 28 and an elastic piece 29. A limit slot 30 is provided in the slide rail 10. The driving rod 37 drives the saw blade 3 or the grinding head 4 to be slidably connected in the slide rail 10. The arc-shaped rotating block 27 is rotatably connected in the limit slot 30. The limit block 28 is fixedly connected to the arc-shaped rotating block 27. The elastic piece 29 is bent in an arc shape. The two ends of the elastic piece 29 in the bending direction are respectively fixedly connected to the limit slot 30. When the arc-shaped rotating block 27 rotates to either side to the limit position, the limit block 28 moves between the elastic piece 29 and the side wall of the limit slot 30 on the other side. The combination of the arc-shaped rotating block 27, the limit block 28 and the elastic sheet 29 can prevent the saw blade 3 and the grinding head 4 from excessive movement or shaking in the slide rail 10, ensuring that they maintain a stable position on the rotating seat 9, which helps to improve processing accuracy. At the same time, it can also protect the saw blade 3 and the grinding head 4 and extend their service life.

[0045] Reference Figure 1 and Figure 11The fixture 2 includes a mounting base 31, a positioning plate 32, and a clamping block 33. The mounting base 31 is rotatably connected to the first base 7 and driven to rotate by a motor. The positioning plate 32 is fixedly connected to the mounting base 31. The positioning plate 32 is provided with a first avoidance groove 34 for the tool to pass through. The positioning plate 32 is provided with a second avoidance groove 35 for the drive rod 37 to move. The clamping block 33 is movably connected to the positioning plate 32. The clamping block 33 is provided with a third avoidance groove 36 for the tool to pass through. The first avoidance groove 34 and the third avoidance groove 36 are arranged opposite to the slide rail 10 on one side of the fixture 2. The fixture 2 also includes two bolts, which are respectively passed through the clamping block 33 and threadedly connected to the positioning plate 32. The two bolts are rotated to achieve the purpose of moving the clamping block 33 and loosely clamping the workpiece. The design of the mounting base 31, the positioning plate 32, and the clamping block 33 facilitates the positioning and clamping of the workpiece. The first avoidance groove 34 and the third avoidance groove 36 are arranged opposite to the slide rail 10, so that the tool can directly act on the target position of the workpiece, thereby improving the processing accuracy. The setting of the second avoidance groove 35 provides sufficient space for the processing operations of the saw blade 3 and the grinding head 4, avoiding interference between the tool and the fixture 2, ensuring the smooth progress of the processing process, and also helping to improve the processing accuracy and quality.

[0046] Reference Figure 1 In summary, the working process of the cylinder 20-slot forming machine according to the embodiment of the present application is as follows: S1 Workpiece Fixing: Place the cylinder 20 to be processed on the positioning plate 32 of the fixture 2 and clamp the workpiece by moving the clamping block 33. The first avoidance groove 34 of the positioning plate 32 and the third avoidance groove 36 of the clamping block 33 are aligned with the corresponding slide rail 10; S2 position adjustment: Use the lead screw and motor to control the sliding of the first seat 7 and the second seat 8 to adjust the relative positions of the clamp 2, saw blade 3, grinding head 4 and driving mechanism 6; S3 Tool Switching: Move the second seat 8 to the designated position, the servo motor 13 drives the hollow rod 12 to rotate rapidly in the opposite direction, and uses centrifugal force to extend the solid rod 11, and move the second seat 8 to the designated position, so that the plug-in block 41 on the solid rod 11 is plugged into the first plug-in slot 15 of the rotating seat 9; the servo motor 13 drives the hollow rod 12 to rotate slowly, driving the rotating seat 9 to rotate; The rotating seat 9 drives the turntable 23 to rotate via the second gear 25, and the limit post 19 moves with the turntable 23. When the position sensor 40 abuts against the corresponding signal device 39, a signal is transmitted to the servo motor 13 to stop it, ensuring the precise positioning of the rotating seat 9 and switching the saw blade 3 or the grinding head 4 to the working position. The servo motor 13 drives the hollow rod 12 to rotate forward quickly, so that the solid rod 11 moves into the hollow rod 12, and the second seat 8 is moved to the specified position again. Through the movement of the first seat 7 and the second seat 8, the hollow rod 12 is matched with the driving rod 37, and the second seat 8 moves to make the driving rod 37 disengage from the slide rail 10; S4 processing operation: After the tool switching is completed, the connector 16 corresponding to the drive rod 37 is axially connected to the hollow plug rod 12, and the solid plug rod 11 is plugged into the second plug slot 17 of the connector 16; the servo motor 13 drives the hollow plug rod 12 to rotate forward. Since the hollow plug rod 12 has been fixed to the connector 16 by air pressure adsorption, and the spiral slide 42 limits the axial movement of the solid plug rod 11, the solid plug rod 11 rotates synchronously with the hollow plug rod 12, thereby driving the drive rod 37 to rotate, so that the saw blade 3 or the grinding head 4 processes the through groove 21 on the cylinder 20.

[0047] During the processing, the fixture 2 rotates 180° to the other side of the hollow insert rod 12 , so that the saw blade 3 or the grinding head 4 processes both sides of the workpiece to ensure the perfection of the through groove 21 on the cylinder 20 .

[0048] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
