Description

Technical Field

[0001] This utility model relates to the technical field of boring fixtures, and in particular to a camshaft boring device. Background Technology

[0002] Boring is a further processing step for forged, cast, or drilled holes. Boring can enlarge the hole diameter, improve accuracy, reduce surface roughness, and also effectively correct the misalignment of the original hole axis. The camshaft is a component in a piston engine, controlling the opening and closing of valves; boring is required during its production. Existing technology publication number CN219852205U discloses a boring device comprising: a hollow boring bar with a boring tool mounted at its front end; and multiple positioning devices distributed on the boring bar for abutting against the inner wall of a cylindrical workpiece. The hollow design of the boring bar reduces its weight; when the boring bar extends into the cylindrical workpiece, the positioning devices are activated and abut against the inner wall of the workpiece, thereby improving the stability of the boring bar, reducing vibration amplitude, and thus improving the boring accuracy of the cylindrical workpiece. However, the clamping effect is poor during the clamping process, and deviations are prone to occur, reducing clamping efficiency. After fixing, it is not easy to adjust the position of the workpiece, resulting in repeated clamping and positioning of the workpiece, which affects the processing efficiency of the workpiece and increases the labor intensity of the operator. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a camshaft boring device that facilitates workpiece position adjustment, avoids misalignment during movement, and ensures stable clamping.

[0004] This utility model discloses a camshaft boring device, comprising a base, an adjusting plate, a placement plate, a position adjusting component, a height adjusting component, a clamping and fixing component, and a clamping component. The adjusting plate is mounted on the top of the base via the position adjusting component, and the placement plate is mounted on the top of the adjusting plate via the height adjusting component. The clamping and fixing component is mounted on the placement plate, and the clamping component is mounted on the left and right sides of the base. When the workpiece is placed on the placement plate, it is limited and fixed by the clamping and fixing component. Simultaneously, the position adjusting component adjusts the position of the workpiece, and the height adjusting component adjusts the height of the workpiece, eliminating the need for repeated clamping and positioning. The clamping component clamps and fixes the end of the workpiece, further ensuring stability during processing, improving work efficiency, and reducing labor intensity.

[0005] Preferably, the position adjustment component includes a precision lead screw, a servo motor, a moving block, two support rods, and two guide blocks. An adjustment groove is formed at the center of the top of the base. The precision lead screw is rotatably installed within the adjustment groove, and its input end is connected to the output end of the servo motor. The moving block is screwed onto the outer wall of the precision lead screw, and its top end is connected to the bottom of the adjustment plate. Support grooves are symmetrically formed on the top of the base about the adjustment groove, and two support rods are respectively installed within these support grooves. The guide blocks are slidably installed on the outer wall of the support rods, and their top ends are connected to the bottom of the adjustment plate. Starting the servo motor drives the precision lead screw to rotate, causing the moving block to move within the adjustment groove, thereby moving the adjustment plate back and forth on the top of the base to adjust the workpiece position. When the adjustment plate moves, it causes the guide blocks to slide on the support rods, increasing structural strength and ensuring stability.

[0006] Preferably, the height adjustment component includes two mounting brackets, two electric telescopic rods, and two sets of limiting rods. The two mounting brackets are symmetrically mounted on the top of the adjustment plate, and the electric telescopic rods are mounted on the top of the mounting brackets. The top telescopic end of the electric telescopic rod is connected to the bottom of the placement plate. Limiting rods are slidably mounted on the left and right sides of the mounting brackets, and the top of the limiting rods is connected to the bottom of the placement plate. Activating the electric telescopic rods can push the placement plate to move up and down, adjusting the height of the workpiece without repeated clamping and positioning. When the placement plate moves, it drives the limiting rods to slide on the mounting brackets, limiting and guiding them to ensure stability.

[0007] Preferably, the clamping and fixing assembly includes multiple support blocks, two sets of extension plates, two sets of second electric telescopic rods, and two sets of clamping blocks. The multiple support blocks are installed on the top of the placement plate, and extension plates are symmetrically installed on the left and right sides of the front and rear end side walls of the placement plate. The second electric telescopic rods are installed on the top of the extension plates, and clamping blocks are installed on the telescopic ends of the second electric telescopic rods. When the workpiece is placed on the top of the placement plate, it is supported by the support blocks. The second electric telescopic rods are activated to push the clamping blocks closer together, so that they can cooperate with the support blocks to clamp and fix the workpiece, prevent movement, ensure stability during boring, and improve machining accuracy.

[0008] Preferably, it also includes two guide frames and two limiting slide rods. The two guide frames are symmetrically installed on the left and right sides of the top of the adjustment plate, and the limiting slide rods are symmetrically installed on the left and right sides of the bottom of the placement plate. The limiting slide rods are slidably installed on the guide frames. When the placement plate moves up and down, it drives the limiting slide rods to slide on the guide frames to limit and guide them, increase the connection strength, and ensure stability.

[0009] Preferably, the clamping component includes two columns, two lead screws, two connecting plates, two sets of support slides, two mounting plates, two clamping heads, and two rotating wheels. The two columns are located on the left and right sides of the base, respectively. Lead screws are screwed onto the columns, with the outer end of the lead screw rotatably connected to the connecting plate and the other end of the lead screw rotatably connected to the mounting plate. Support slides are symmetrically slidably mounted on the columns about the lead screws, with the outer end of the support slides connected to the connecting plate and the other end of the support slides connected to the mounting plate. Clamping heads are mounted on the mounting plates, and rotating wheels are mounted on the input end of the lead screws. After the workpiece is adjusted, rotating the rotating wheels drives the lead screws to move on the columns, causing the clamping heads to clamp the workpiece, further ensuring stability. When the mounting plates move, they drive the support slides to slide on the columns, increasing structural strength and ensuring stability.

[0010] Preferably, it also includes a cartridge holder, a cartridge block, and a locking bolt. The cartridge holder is installed at the bottom of the right column, and the cartridge block is installed at the bottom of the cartridge holder. The top of the base has a cartridge hole that matches the cartridge holder, and the locking bolt is installed on the right side wall of the cartridge holder. Moving the cartridge holder allows the cartridge block to be inserted into the cartridge hole, and tightening the locking bolt fixes the cartridge holder, which can tighten and fix both ends of the workpiece. Loosening the locking bolt allows the right column to be removed for easy processing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the workpiece is placed above the placement plate, and the workpiece is limited and fixed by the clamping and fixing component. At the same time, the position adjustment component can adjust the position of the workpiece, and the height adjustment component can drive the workpiece to adjust the height. There is no need for repeated clamping and positioning. The end of the workpiece can be tightened and fixed by the clamping component, which further ensures the stability during processing, which is conducive to improving work efficiency and reducing labor intensity.

Two columns 18 are located on the left and right sides of the base 1, respectively. A screw rod 19 is screwed onto the column 18. The outer end of the screw rod 19 is rotatably connected to the connecting plate 20, and the other end of the screw rod 19 is rotatably connected to the mounting plate 22. The column 18 has... A support slide rod 21 is symmetrically slidably installed on the lead screw 19. The outer end of the support slide rod 21 is connected to the connecting plate 20, and the other end of the support slide rod 21 is connected to the mounting plate 22. A tightening head 23 is installed on the mounting plate 22. A rotating wheel 24 is installed on the input end of the lead screw 19.

[0020] The workpiece is placed on top of the placement plate 10 and supported by the support block 14. Activating the second electric telescopic rod 16 pushes the clamping blocks 17 closer together, allowing them to cooperate with the support block 14 to clamp and fix the workpiece, preventing movement and ensuring stability during boring, thus improving machining accuracy. Activating the servo motor 3 drives the precision lead screw 2 to rotate, causing the moving block 4 to move within the adjusting groove, thereby moving the adjusting plate 5 back and forth on the top of the base 1 to adjust the workpiece position.

During operation, the workpiece is placed on top of the placement plate 10 and supported by the support block 14. Activating the second electric telescopic rod 16 pushes the clamping blocks 17 closer together, allowing them to cooperate with the support block 14 to clamp and fix the workpiece, preventing movement. Activating the servo motor 3 drives the precision lead screw 2 to rotate, causing the moving block 4 to move within the adjusting groove. This, in turn, moves the adjusting plate 5 back and forth on the top of the base 1, adjusting the workpiece position. As the adjusting plate 5 moves, it causes the guide block 7 to slide on the support rod 6. Activating the electric telescopic rod 9 pushes the placement plate 10 up and down, adjusting the workpiece position. The height of the workpiece does not require repeated clamping and positioning.
