Description

Technical Field

[0001] This invention relates to the field of cylinder groove forming machine technology, and in particular to a cylinder groove rapid forming machine. Background Technology

[0002] Reference Figure 12 This is a schematic diagram of the cylinder structure of the compressor in this application. The compressor has a through groove on the cylinder that is connected to the center hole. In the prior art, to process this groove, two machines are usually required to perform grooving and grinding respectively.

[0003] However, cylinders produced using this method require transfer from the grooving equipment to the grinding equipment, involving steps such as workpiece disassembly, transport, and re-clamping. For mass production, the transfer time for each batch of workpieces accumulates, significantly reducing output per unit time. Furthermore, during the secondary clamping, the workpiece's positioning on the grinding equipment is difficult to perfectly match the datum used during grooving, potentially leading to deviations in the groove's positional accuracy. Summary of the Invention

[0004] To facilitate the machining and forming of cylinder grooves, this application provides a rapid prototyping machine for cylinder grooves.

[0005] The cylinder groove rapid prototyping machine provided in this application adopts the following technical solution:

[0006] A cylinder groove rapid forming machine includes a machine body, a fixture, several saw blades, several grinding heads, a switching mechanism, and a driving mechanism. A first seat and a second seat are movably connected to the machine body. The fixture is rotatably connected to the first seat. The switching mechanism includes a rotating seat and several driving rods. The rotating seat is rotatably connected to the first seat. Several slide rails are provided on the rotating seat. Several driving rods correspond to several slide rails and are movably connected to their respective slide rails. Several driving rods can disengage from their respective slide rails. Several saw blades and several grinding heads are respectively mounted on their respective driving rods. The driving mechanism is used to drive the rotation of the driving rods and the rotation of the rotating seat.

[0007] By adopting the above technical solution, the fixture is used to fix the workpiece, and the saw blade and grinding head can be used for cutting and grinding processes respectively. The switching mechanism can switch between the saw blade and the grinding head to meet different processing needs. 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, which is convenient for processing cylinder grooves of different sizes and shapes, improving the versatility and flexibility of the equipment and facilitating the forming of cylinder grooves.

[0008] Preferably, the driving mechanism includes a solid insert rod, a hollow insert rod, and a servo motor. The hollow insert rod is rotatably connected to the second seat, and the solid insert rod is threaded onto the hollow insert rod. The rotating seat has a first insertion slot that can be inserted and engaged with the solid insert rod. The servo motor is used to drive the rotation of the hollow insert rod. When it is necessary to drive the rotating seat to rotate, the servo motor drives the hollow insert rod to rotate in the opposite direction, so that the solid insert rod extends out and engages with the first insertion slot.

[0009] By adopting the above technical solution, a servo motor drives the hollow insert rod, and the solid insert rod engages with the first insertion slot on the rotating seat to achieve rotation control of the rotating seat. This structural design is simple and reliable in transmission, and can complete the blade changing operation without the need for an additional motor, providing stable power transmission for the switching of saw blades and grinding heads as well as subsequent processing operations.

[0010] Preferably, each of the driving rods is provided with a connector that can mate with a hollow rod, and the connector is provided with a second insertion slot. When the driving rod needs to be driven to rotate, the connector mates with the hollow rod, and the solid rod moves to mate with the second insertion slot. The rotation of the hollow rod drives the driving rod to rotate synchronously through the solid rod.

[0011] By adopting the above technical solution, the connector on the drive rod mates with the hollow insert rod, and the solid insert rod mates with the second insertion slot on the connector, thus enabling the drive rod to rotate. This design allows the drive mechanism to precisely drive the rotating seat and the drive rod separately, facilitating the rotation of the rotating seat at different processing stages, such as when switching tools, and rotating the drive rod during processing to drive the saw blade or grinding head to rotate, ensuring smooth processing.

[0012] Preferably, it also includes a limiting component, which is used to limit the rotation of the rotating seat. The limiting component includes a limiting post, a position sensor, and several signal devices. Several limiting slots are opened on the circumferential side of the rotating seat, and several signal devices correspond to several limiting slots respectively. The first seat is rotatably connected to a turntable, and the rotating seat drives the turntable to rotate. The limiting post is slidably connected to the turntable, and the position sensor is installed on the limiting post. When the turntable rotates once, the limiting post engages with different limiting slots, and the position sensor abuts against the corresponding signal device. When the position sensor abuts against the designated signal device, the position sensor transmits a signal to the servo motor, causing the servo motor to stop rotating.

[0013] By adopting the above technical solution, and through the cooperation of limit posts, position sensors, and signal devices, the number of rotations and position of the rotary seat can be precisely controlled. When the rotary seat drives the turntable to the designated position, the position sensor and the corresponding signal device abut against each other, causing the servo motor to stop rotating, ensuring that the rotary seat stops accurately in the required position, and guaranteeing that the saw blade or grinding head can accurately switch to the working position, thereby improving the processing accuracy and reliability.

[0014] Preferably, the turntable is provided with a first gear, and the rotating seat is provided with a second gear, and the first gear and the second gear are meshed together.

[0015] By adopting the above technical solution, the turntable can accurately follow the rotation of the rotating seat, thereby ensuring that the limit post can accurately engage with the limit slot and the position sensor can accurately contact the signal device, further improving the accuracy of the rotation angle control of the rotating seat.

[0016] Preferably, it also includes a limiting component, which is used to limit the position of the saw blade and grinding head on the rotating seat. The limiting component includes an arc-shaped rotating block, a limiting block, and an elastic plate. A limiting groove is formed in the slide rail. The drive rod drives the saw blade or grinding head to be slidably connected in the slide rail. The arc-shaped rotating block is rotatably connected in the limiting groove. The limiting block is fixedly connected to the arc-shaped rotating block. The elastic plate is curved in an arc shape. The two ends of the bending direction of the elastic plate are respectively fixedly connected in the limiting groove. When the arc-shaped rotating block rotates to the limit position on either side, the limiting block moves between the elastic plate and the side wall of the limiting groove on the other side.

[0017] By adopting the above technical solution, the combination of arc-shaped rotating block, limiting block and elastic plate can prevent the saw blade and grinding head from moving or shaking excessively in the slide rail, ensuring that they maintain a stable position on the rotating seat, which helps to improve processing accuracy, and at the same time protects the saw blade and grinding head and extends their service life.

[0018] Preferably, the fixture includes a mounting base, a positioning plate, and a clamping block. The mounting base is rotatably connected to a first base, and the positioning plate is fixedly connected to the mounting base. The positioning plate has a first clearance groove for the tool to pass through and a second clearance groove for the drive rod to move. The clamping block is movably connected to the positioning plate and has a third clearance groove for the tool to pass through. The first clearance groove and the third clearance groove are arranged opposite to the slide rail facing the fixture.

[0019] By adopting the above technical solution, the design of the mounting base, positioning plate, and clamping block facilitates the positioning and clamping of the workpiece. The first and third clearance grooves are positioned directly opposite the slide rail, allowing the cutting tool to directly act on the target position of the workpiece, improving machining accuracy. The second clearance groove provides sufficient space for the machining operations of the saw blade and grinding head, avoiding interference between the cutting tool and the fixture, ensuring smooth machining, and also contributing to improved machining accuracy and quality.

[0020] The main technical effects of this invention are reflected in the following aspects:

[0021] 1. The fixture of this invention is used to fix the workpiece. The saw blade and grinding head can be used for cutting and grinding processes, respectively. The switching mechanism can switch between the saw blade and the grinding head to meet different processing needs. 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, which is convenient for processing cylinder grooves of different sizes and shapes, improving the versatility and flexibility of the equipment and facilitating the forming of cylinder grooves.

[0022] 2. This invention uses a servo motor to drive a hollow insert rod, and utilizes the insertion and engagement of the solid insert rod with the first insertion slot on the rotating seat to achieve rotation control of the rotating seat. This structural design is simple and reliable in transmission, and it can complete the tool changing operation without the need for an additional motor. It can reduce the use of motors for tool changing and supporting equipment such as spindle boxes, thereby reducing the production budget of the grinding machine. It also provides stable power transmission for the switching of saw blades and grinding heads and subsequent processing operations.

[0023] 3. In this invention, the connector on the drive rod engages with the hollow insert rod, and the solid insert rod engages with the second insertion slot on the connector, enabling the drive rod to rotate. This design allows the drive mechanism to precisely drive the rotating seat and the drive rod separately, facilitating different processing stages, such as rotating the rotating seat when switching tools, and rotating the drive rod during processing to drive the saw blade or grinding head to rotate, ensuring smooth processing.

[0037] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0038] This application discloses a cylinder groove rapid prototyping machine.

[0039] Reference Figure 1The cylinder groove rapid forming machine of this embodiment includes a machine body 1, a fixture 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 machine body 1. The first seat 7 slides in the horizontal direction, and the second seat 8 slides in the direction perpendicular to the movement of the first seat 7. The first seat 7 and the second seat 8 are controlled to move by a combination of a lead screw and a motor.

[0040] 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 drive 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 drive rods 37 correspond to the two slide rails 10 respectively. The two drive rods 37 are movably connected to the corresponding slide rails 10 respectively, and the two drive rods 37 can move away from the corresponding slide rails 10. The saw blade 3 and the grinding head 4 are respectively installed on the corresponding drive rods 37. The driving mechanism 6 is used to drive the rotation of the drive rods 37 and the rotation of the rotating seat 9.

[0041] Reference Figure 1 The clamp 2 is used to fix the workpiece. The saw blade 3 and grinding head 4 can be used for cutting and grinding processes, respectively. The switching mechanism 5 can switch between the saw blade 3 and the grinding head 4 to meet different processing needs. 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, which is convenient for processing cylinder 20 slots of different sizes and shapes, improving the versatility and flexibility of the equipment and facilitating the processing and forming of cylinder 20 slots.

[0042] Reference Figure 6 , Figure 8 and Figure 9 The drive mechanism 6 includes a solid insert rod 11, a hollow insert rod 12, and a servo motor 13. The hollow insert rod 12 is rotatably connected to the second base 8. Multiple threads are formed inside the hollow insert rod 12, meaning multiple spiral slides 42 are evenly distributed around the circumferential inner wall of the hollow insert rod 12. Multiple sliding heads 43 are fixedly connected to one end of the solid insert rod 11 along its axial direction. Each sliding head 43 corresponds to one of the multiple spiral slides 42, and the sliding heads 43 are slidably connected within the multiple spiral slides 42, causing the solid insert rod... 11 is threaded onto the hollow insert rod 12. A counterweight block 41 is fixedly connected to the end of the solid insert rod 11 away from the hollow insert rod 12. The rotating seat 9 has a first insertion slot 15 that can be inserted and engaged with the insertion block 41 on the solid insert rod 11. The servo motor 13 is used to drive the rotation of the hollow insert rod 12. When the rotating seat 9 needs to be driven to rotate, the servo motor 13 drives the hollow insert rod 12 to rotate in the opposite direction, so that the solid insert rod 11 extends out to allow the insertion block 41 to be inserted and engaged with the first insertion slot 15.

[0043] Reference Figure 7 and Figure 10 The servo motor 13 reverses to drive the hollow insert rod 12, using centrifugal force to extend the solid insert rod 11 and engage with the first insertion slot 15 on the rotating seat 9, thus controlling the rotation of the rotating seat 9. Reversing the rotation causes the solid insert rod 11 to retract into the hollow insert rod 12 when not in operation. This design is simple and reliable, and it eliminates the need for an additional motor to change tools, reducing the need for motors and spindle boxes used for tool changing, thereby reducing the production budget of the grinding machine. Furthermore, it provides stable power transmission for switching between the saw blade 3 and the grinding head 4, as well as for subsequent processing operations.

[0044] Reference Figure 2 and Figure 3 Each of the two drive rods 37 has a connector 16 fixedly connected to it, which can mate with the hollow insert rod 12. The connector 16 has a second insertion slot 17 that can mate with the insertion block 41 on the solid insert rod 11. When the drive rod 37 needs to be rotated, the connector 16 mates with the hollow insert rod 12, and the insertion block 41 on the solid insert rod 11 mates with the second insertion slot 17. The engagement of the connector 16 on the drive rod 37 with the hollow insert rod 12 and the engagement of the solid insert rod 11 with the second insertion slot 17 on the connector 16 enables the rotation of the drive rod 37. This design allows the drive mechanism 6 to precisely drive the rotating seat 9 and the drive rod 37 separately, facilitating the rotation of the rotating seat 9 during tool switching and the rotation of the drive rod 37 during processing to drive the saw blade 3 or grinding head 4, ensuring smooth processing.

[0045] Reference Figure 6 and Figure 7 The hollow insert rod 12 has an air hole 38. A vacuum pump is installed on the body 1. The air hole 38 is connected to the vacuum pump. When the connector 16 is engaged with the hollow insert rod 12 and the solid insert rod 11 is engaged with the second insertion slot 17, the vacuum pump evacuates the hollow insert rod 12, so that the drive rod 37 is adsorbed onto the hollow insert rod 12 by air pressure, reducing the possibility of the drive rod 37 falling off.

[0046] Reference Figure 2 , Figure 3 and Figure 5It also includes a limiting member 18, which is used to limit the rotation of the rotating seat 9. The limiting member 18 includes a limiting post 19, a position sensor 40 and two signal devices 39. Two limiting slots 22 are opened on the circumferential side of the rotating seat 9. The two signal devices 39 correspond to the two limiting slots 22 respectively. A turntable 23 is rotatably connected to the first seat 7. The rotating seat 9 can drive the turntable 23 to rotate. That is, a first gear 24 is coaxially and fixedly connected to the turntable 23, and a second gear 25 is coaxially and fixedly connected to the rotating seat 9. The first gear 24 and the second gear 25 are meshed together. The limiting post 19 is slidably connected to the turntable 23 along the rotation direction perpendicular to the turntable 23. The position sensor 40 is installed on the limiting post 19. When the turntable 23 rotates once, the limiting post 19 engages with different limiting 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.

[0047] Reference Figure 2 , Figure 3 and Figure 5 Through the cooperation of the limit post 19, position sensor 40, and signal device 39, the number of rotations and position of the rotating seat 9 can be precisely controlled. When the rotating seat 9 drives the turntable 23 to rotate to the designated position, the position sensor 40 abuts against the corresponding signal device 39, causing the servo motor 13 to stop rotating, ensuring that the rotating seat 9 stops accurately at the required position, and ensuring that the saw blade 3 or grinding head 4 can accurately switch to the working position, thus improving the processing accuracy and reliability.

[0048] Reference Figure 3 and Figure 4 It also includes a limiting component 26, which is used to limit the position of the saw blade 3 and the grinding head 4 on the rotating seat 9. The limiting component 26 includes an arc-shaped rotating block 27, a limiting block 28 and an elastic plate 29. A limiting groove 30 is opened in the slide rail 10. The drive 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 limiting groove 30. The limiting block 28 is fixedly connected to the arc-shaped rotating block 27. The elastic plate 29 is bent into an arc shape. The two ends of the bending direction of the elastic plate 29 are respectively fixedly connected in the limiting groove 30. When the arc-shaped rotating block 27 rotates to the limit position on either side, the limiting block 28 moves between the elastic plate 29 and the side wall of the limiting groove 30 on the other side. The combination of the arc-shaped rotating block 27, the limiting block 28, and the elastic plate 29 can prevent the saw blade 3 and the grinding head 4 from moving or shaking excessively within the slide rail 10, ensuring that they maintain a stable position on the rotating seat 9, which helps to improve processing accuracy, while also protecting the saw blade 3 and the grinding head 4 and extending their service life.

[0049] 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 is driven to rotate by a motor. The positioning plate 32 is fixedly connected to the mounting base 31 and has a first clearance groove 34 for the tool to pass through and a second clearance groove 35 for the drive rod 37 to move. The clamping block 33 is movably connected to the positioning plate 32 and has a third clearance groove 36 for the tool to pass through. The first clearance groove 34 and the third clearance groove 36 are positioned opposite the slide rail 10 facing the fixture 2. The fixture also includes two bolts, which pass through the clamping block 33 and are threaded onto the positioning plate 32. Rotating the two bolts moves the clamping block 33 and tightens or loosens the workpiece. The design of the mounting base 31, positioning plate 32, and clamping block 33 facilitates the positioning and clamping of the workpiece. The first clearance groove 34 and the third clearance groove 36 are set directly opposite the slide rail 10, so that the cutting tool can directly act on the target position of the workpiece, improving the machining accuracy. The setting of the second clearance groove 35 provides sufficient space for the machining operation of the saw blade 3 and the grinding head 4, avoids interference between the cutting tool and the fixture 2, ensures the smooth progress of the machining process, and also helps to improve the machining accuracy and quality.

[0050] Reference Figure 1 In summary, the working process of the cylinder 20-groove forming machine according to the embodiments of this application is as follows:

[0051] 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 clearance groove 34 of the positioning plate 32 and the third clearance groove 36 of the clamping block 33 are aligned with the corresponding slide rail 10;

[0052] S2 Position Adjustment: The first seat 7 and the second seat 8 are controlled to slide using a lead screw and a motor, thereby adjusting the relative positions of the clamp 2, saw blade 3, grinding head 4 and drive mechanism 6.

[0053] S3 Tool Switching: Move the second seat 8 to the designated position, the servo motor 13 drives the hollow insert rod 12 to rotate rapidly in the opposite direction, using centrifugal force to extend the solid insert rod 11, move the second seat 8 to the designated position, so that the insertion block 41 on the solid insert rod 11 is inserted into the first insertion slot 15 of the rotating seat 9; the servo motor 13 drives the hollow insert rod 12 to rotate slowly, causing the rotating seat 9 to rotate;

[0054] The rotating seat 9 drives the turntable 23 to rotate via the second gear 25. The limit post 19 moves with the turntable 23. When the position sensor 40 comes into contact with the corresponding signal device 39, the signal is transmitted to the servo motor 13 to stop it, ensuring that the rotating seat 9 is accurately positioned and that the saw blade 3 or grinding head 4 is switched to the working position.

[0055] Servo motor 13 drives hollow insert rod 12 to rotate rapidly in the forward direction, causing solid insert rod 11 to move into hollow insert rod 12. Then, the second seat 8 is moved to the designated position. Through the movement of the first seat 7 and the second seat 8, the hollow insert rod 12 engages with the drive rod 37. The movement of the second seat 8 causes the drive rod 37 to disengage from the slide rail 10.

[0056] S4 processing operation: After the tool switching is completed, the connector 16 of the corresponding drive rod 37 is axially connected with the hollow rod 12, and the solid rod 11 is inserted into the second insertion slot 17 of the connector 16; the servo motor 13 drives the hollow rod 12 to rotate forward. Since the hollow rod 12 has been fixed to the connector 16 by air pressure adsorption, and the spiral slide 42 restricts the axial movement of the solid rod 11, the solid rod 11 rotates synchronously with the hollow 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.

[0057] 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 can process both sides of the workpiece to ensure the perfection of the through groove 21 on the cylinder 20.

[0058] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
