Description

Technical Field

[0001] This utility model belongs to the field of reamer technology, and in particular relates to a hard reamer production device with adjustable processing position. Background Technology

[0002] Carbide reamers are high-precision hole-making tools made of cemented carbide. They are mainly used for finishing machined holes to improve hole diameter accuracy and surface finish. Their core advantages lie in the material's high hardness, wear resistance, and good thermal stability. They are suitable for machining difficult-to-cut materials such as alloy steel, stainless steel, cast iron, and titanium alloys, and are widely used in automotive manufacturing, aerospace, and mold processing.

[0003] Chinese patent application CN219881827U discloses an adjustable machining fixture for high-strength precision reamer machining, comprising: a protective shell, an L-shaped fixing plate at the upper end of the protective shell, a motor on one side of the protective shell, a threaded rod at the output end of the motor, a threaded block at the upper end of the threaded rod, a slider at the upper end of the threaded block, and a symmetrical outer shell at the upper end of the slider; a clamping block inside the outer shell, several telescopic rods at the lower end of the clamping block, each telescopic rod having a spring on its outer side, and a limiting plate on one side of the outer shell; the fixture is adjusted by a hydraulic cylinder to clamp the reamer in the outer shell, and the position of the reamer is adjusted by the motor to facilitate machining; the limiting plate and support block on the slider prevent the reamer from shifting during machining, simplifying operation and effectively ensuring efficient reaming operations.

[0004] Although this patented device can move the reamer left and right, it requires the clamping and fixing structure at the top to be released before it can move. It also cannot be rotated. After the current working surface is finished, the operator needs to manually remove it and flip the working surface for installation. This method is not only inefficient, but also increases labor costs.

[0005] To address these issues, we provide a hard reamer production apparatus with adjustable machining position. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Please see Figure 1-6This utility model relates to a production device for a hard reamer with adjustable processing position. It includes a base 1, a drive assembly 2 fixedly connected to one side of the base 1, and a rotary clamping assembly 3 threadedly connected to the surface of the drive assembly 2. The drive assembly 2 includes a moving groove 21 and a sliding groove 22 formed on the top of the base 1. A lead screw 23 is fixedly connected to the inner cavity of the moving groove 21 via a bearing. One end of the lead screw 23 extends through to the outside of the base 1 and is fixedly connected to a servo motor 24. The rotary clamping assembly 3 includes a moving block 31 threadedly connected to the surface of the lead screw 23. A moving seat 32 is fixedly connected to the top of the moving block 31. A moving groove 33 is formed on one side of the top of the moving seat 32. A lead screw 34 is movably connected to the inner cavity of the moving groove 33 via a bearing. The other end of rod 34 extends through to the outside of movable seat 32 and is fixedly connected to worm gear 35. Worm gear 36 is engaged at the bottom of worm gear 35. Servo motor 37 is fixedly connected to one end of worm gear 36. Movable block 38 is threadedly connected to the surface of screw 34. Mounting seat 39 is fixedly connected to the top of movable block 38. Mounting seat 310 is fixedly connected to the other side of the top of movable seat 32. Fixing ring 311 is movably connected to the inner cavity of mounting seat 39 through bearing. Receiving seat 312 is movably connected to the inner cavity of mounting seat 310 through bearing. Worm gear 313 is fixedly connected to one end of receiving seat 312. Worm gear 314 is engaged at the bottom of worm gear 313. Servo motor 315 is fixedly connected to one end of worm gear 314.

[0029] Specifically: When the servo motor 37 is working, it can drive the worm wheel 35 to rotate through the worm gear 36, which in turn drives the lead screw 34 to rotate. The lead screw 34 drives the mounting base 39 to move through the moving block 38. Since the fixing ring 311 is installed in the inner cavity of the mounting base 39, the mounting base 39 can drive the fixing ring 311 and the clamping plate 317 and hydraulic telescopic rod 318 in its inner cavity to move. This allows the clamping position of the hard reamer to be selected according to the processing needs, avoiding processing interference.

[0030] Example 2

[0031] Please see Figure 1-6Based on Embodiment 1, a support base is fixedly connected to the bottom of servo motor 24. One side of the support base is fixedly connected to the base 1. Reinforcing ribs are fixedly connected to both the front and rear ends of the bottom of the support base. Slider 316 is fixedly connected to both the front and rear ends of the bottom of the movable base 32. The slider 316 is slidably connected to the slide groove 22. The rotating clamping assembly 3 also includes a clamping plate 317 disposed in the inner cavity of the fixed ring 311 and the receiving seat 312. A hydraulic telescopic rod 318 is fixedly connected to the top of the clamping plate 317. The other end of the hydraulic telescopic rod 318 is fixedly connected to the surface of the fixed ring 311 and the receiving seat 312 through a connecting seat. One side of servo motor 37 is fixedly connected to the surface of the movable base 32. A protective cover 319 is provided on the surface of servo motor 37. The protective cover 319 is fixedly connected to the surface of the movable base 32 through bolts. The bottom of servo motor 315 is fixedly connected to the movable base 32. A rubber pad is bonded to the side of the clamping plate 317 that contacts the surface of the hard reamer with adhesive. The surface of the rubber pad is provided with anti-slip texture.

[0032] Specifically: the support base and reinforcing ribs enhance the stability of the servo motor 24 installation, reduce the impact of vibration generated by the servo motor 24 during operation on the device, and ensure the stability of the drive assembly 2. The slider 316 is slidably connected to the slide groove 22, guiding the movement of the moving seat 32, making the moving seat 32 more stable during movement, avoiding deviation, and ensuring the accuracy of position adjustment. The clamping plate 317 and hydraulic telescopic rod 318 can firmly clamp hard reamers of different specifications, improving the versatility of the device, while ensuring the reamer is properly clamped. The protective cover 319 will not loosen during the operation, and it can protect the servo motor 37, preventing damage to the servo motor 37 from debris, liquids, etc. generated during the processing, thus extending the service life of the servo motor 37. This design enhances the stability of the installation of the servo motor 315, ensuring stable power transmission when driving the bearing 312 to rotate, and ensuring the accuracy of rotation adjustment. The rubber pad and anti-slip texture increase the friction between the servo motor and the hard reamer, preventing the reamer from slipping during processing or adjustment, and further ensuring the stability of the clamping.

[0033] The working principle of this utility model is as follows: First, the hard reamer is passed through the inner cavity of the fixing ring 311. Then, one end of the hard reamer contacts the inner wall of the receiving seat 312. Then, the hydraulic telescopic rod 318 on the surface of the receiving seat 312 is activated to push the clamping plate 317 to clamp the reamer in the inner cavity of the receiving seat 312. Then, the servo motor 37 is activated, which drives the worm gear 36 to rotate. The worm gear 36 drives the worm wheel 35 to rotate, which in turn drives the lead screw 34 to rotate. This causes the moving block 38 to move along the lead screw 34 in the moving groove 33, which in turn moves the mounting seat 39, the fixing ring 311, the clamping plate 317, and the hydraulic telescopic rod 318. A suitable clamping position is selected according to the processing requirements. After moving to the designated position, the servo motor 37 is turned off. Then, the servo motor 37 is activated again. The hydraulic telescopic rod 318 on the surface of the fixed ring 311 pushes the clamping plate 317 to clamp the other end of the reamer in the inner cavity of the fixed ring 311. When the horizontal position needs to be adjusted, the servo motor 24 starts, driving the lead screw 23 to rotate, causing the moving block 31 to move along the lead screw 23 in the moving groove 21, thereby driving the moving seat 32 and the rotating clamping assembly 3 above and the reamer to adjust their horizontal position. When the reamer needs to be rotated to change the machining surface, the servo motor 315 starts, driving the worm gear 314 to rotate. The worm gear 314 drives the worm wheel 313 to rotate, thereby driving the receiving seat 312 to rotate. The receiving seat 312 drives the reamer and the fixed ring 311 to rotate, realizing the rotation adjustment of the reamer. The machining surface can be switched without releasing the clamp.
