Description

[0002] Reaming is a processing method, specifically referring to the process of using a tool to cut a micro layer from the hole wall of a workpiece to improve its dimensional accuracy and hole surface quality. At present, there are usually two processing methods for reaming. The first method is to fix the tool, use a clamping device to clamp the workpiece to be processed, and then drive the workpiece to rotate through a driving device. As the workpiece gradually approaches the tool, the tool cuts the workpiece to complete the reaming operation; the second method is to fix the workpiece on the workbench, drive the tool to rotate through a driving device, and as the rotating tool gradually approaches the workpiece to be processed, the tool cuts the workpiece to complete the reaming operation.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] A reaming tool, such as Figures 1 to 6As shown, it includes a support frame 1, on which a power head 2 is slidably arranged, and an output end of the power head 2 is connected to a tool 4. Specifically, a slide seat 7 is slidably arranged on the support frame 1, on which a mounting seat 9 is mounted, and the power head 2 is mounted on the mounting seat 9. It should be noted that the slide seat 7 is slidably arranged on the support frame 1 through the cooperation of a slider and a slide rail, and the mounting seat 9, the power head 2 and the tool 4 are driven to slide by the sliding of the slide seat 7, thereby realizing the change of the position of the tool 4.

[0026] A clamping seat 3 for clamping the workpiece is provided on the support frame 1, and the tool 4 is aligned with the workpiece on the clamping seat 3. The power head 2 is used to drive the tool 4 to rotate and perform reaming processing on the workpiece on the clamping seat 3. A driving member 8 is provided on the support frame 1, and the output end of the driving member 8 is connected to the slide 7. The driving member 8 is used to drive the slide 7 to approach or move away from the clamping seat 3. The driving member 8 is preferably a cylinder, which drives the slide 7 to slide and drives the mounting seat 9, the power head 2 and the tool 4 to approach or move away from the workpiece on the clamping seat 3 through the driving member 8, so that the rotating tool 4 completes the reaming processing on the workpiece on the clamping seat 3.

[0027] A shock-absorbing buffer 14 is arranged on the support frame 1, a limit block 15 corresponding to the shock-absorbing buffer 14 is arranged on the slide 7, a shock-absorbing block 16 is arranged on the limit block 15, and when the slide 7 slides, the output end of the shock-absorbing buffer 14 can abut against the shock-absorbing block 16; a limited position seat 17 is arranged on the support frame 1, a limited position block 2 18 is arranged on the slide 7, a shock-absorbing block 2 19 is arranged on the limit block 2 18, and when the slide 7 slides, the limit seat 17 can abut against the shock-absorbing block 2 19, so as to limit the slide 7, and further limit the stroke of the tool 4.

[0028] It should be noted that when the slide seat 7 slides to the corresponding position, the shock-absorbing buffer 14 absorbs the impact force and provides buffering, thereby reducing vibration. The shock-absorbing block 16 and the shock-absorbing block 2 19 are both made of rubber material, and the elastic properties of rubber can effectively reduce impact and vibration.

[0029] A support seat 5 is provided on the support frame 1, and a bearing 6 is provided on the support seat 5. The tool 4 is passed through the bearing 6 and the two are coaxially arranged.

The seat body 2 32 and the seat body 1 31 can be assembled to form a clamping port 29 adapted to the workpiece. The driving member 3 28 drives the seat body 2 32 to move toward the seat body 1 31 and gradually approach it, so that the seat body 2 32 and the seat body 1 31 are assembled to clamp the workpiece. When the workpiece needs to be removed, the driving member 3 28 drives the seat body 2 32 to move toward the seat body 1 31 and gradually move away from it, so that the seat body 2 32 is separated from the seat body 1 31.

[0038] A positioning protrusion 30 is provided on the seat body 1 31, and a positioning groove 33 is opened on the seat body 2 32. When the seat body 1 31 and the seat body 2 32 are assembled, the positioning protrusion 30 is inserted into the positioning groove 33. The positioning protrusion 30 cooperates with the positioning groove 33 to ensure the relative stability of the seat body 1 31 and the seat body 2 32, thereby ensuring that the seat body 1 31 and the seat body 2 32 cooperate to stably clamp the workpiece, thereby ensuring the stability of the workpiece.
