Description

Technical Field

[0001] This utility model relates to the field of milling cutter production and processing technology, specifically a clamping device for high-precision milling cutter grinding. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling. During operation, each cutting tooth sequentially and intermittently removes the excess material from the workpiece. It is mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces. There are many types of milling cutters with different structures and a wide range of applications, including automotive parts, aircraft parts, molds, shipbuilding, and many other fields.

[0003] According to the authorization announcement number CN218575082U, a high-precision clamping device for graphite end mill production is disclosed, including a worktable; a support frame is fixedly connected to the top of the worktable; a grinding device is fixedly connected to the side wall of the support frame; a support base is fixedly connected to the top of the worktable; a rotating wheel is rotatably connected to the side wall of the support base; a pair of connecting plates are fixedly connected to the side wall of the rotating wheel; a telescopic electric cylinder is fixedly connected to the side wall of each pair of connecting plates that are close to each other; a cylinder is fixedly connected to the end of the telescopic electric cylinder; and multiple fixed blocks are slidably connected to the middle of the cylinder. By providing a cylinder on the worktable, it can adapt to end mills of different sizes, perform high-precision clamping of end mills of different sizes, thereby reducing the offset problem caused by different specifications of end mills during clamping, improving the accuracy of end mill clamping, reducing defects generated in the end mill production process, and improving the production quality of end mills.

[0004] However, the above-mentioned device still has shortcomings. It uses a cylinder to drive a fixed block to clamp milling cutters of different sizes, thereby ensuring the stability of the milling cutter during the machining process. However, the clamped milling cutter body is difficult to rotate or adjust, which means that the milling cutter needs to be adjusted during the machining process to ensure the completion of the milling. Frequent adjustment of the milling cutter affects the machining efficiency. Utility Model Content

The clamping block is pneumatically connected to one end of the cylinder. The second motor is fixedly connected to the bottom of the mounting plate. The waste residue box is installed below the mounting plate. The output shaft of the first motor passes through the fixed support frame and is fixedly connected to the mounting plate. Similarly, the output shaft of the second motor passes through the mounting plate and is fixedly connected to the bottom of the clamping cylinder. The first motor can drive the mounting plate to rotate, thereby adjusting the machining position of the milling cutter. In conjunction with the second motor driving the clamping cylinder to rotate, the machining surface of the milling cutter can be rotated and adjusted.

The snap-fit ​​rod is fixedly connected to the top of the outer side of the box body and snap-fitted into a slot, so that the box body can be placed under the clamping cylinder, ensuring that the waste residue after grinding can fall into the box body, reducing the work of manually cleaning the table.

[0010] Preferably, the top of the clamping plate is set as an inclined surface, which facilitates the insertion of the milling cutter bar.

[0011] Preferably, there are three sets of mounting slots, each located below the cylinder, to ensure stable clamping of the milling cutter rod and to ensure the clamping effect of the cylinder driving the clamping block.

[0012] Preferably, the size of the waste residue box is larger than the size of the mounting plate to ensure the effective collection of waste residue.

[0013] Preferably, one end of the clamping block is provided with a rubber pad to increase the friction between the clamping block and the milling cutter, ensuring the effective fixation of the milling cutter.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This high-precision milling cutter grinding clamping device uses a first motor to drive the mounting plate to rotate, thereby adjusting the milling cutter's machining position. In conjunction with a second motor to drive the clamping cylinder to rotate, the machining surface of the milling cutter can be adjusted by rotation. This reduces the need to handle the milling cutter during use and improves the efficiency of milling cutter grinding.

[0016] 2. This high-precision milling cutter grinding clamping device is installed inside the cylinder by springs and clamping plates. During the placement of the milling cutter, the bottom milling cutter shank can be inserted into the clamping plate and then clamped by clamping blocks. This avoids the need for manual hand support during the clamping process and ensures the stability of the milling cutter. Attached Figure Description

The first motor 3 can drive the mounting plate 2 to rotate, thereby adjusting the machining position of the milling cutter. In conjunction with the second motor 7 driving the clamping cylinder 4 to rotate, the machining surface of the milling cutter can be rotated and adjusted. During use, the milling cutter needs to be removed, improving the working efficiency of milling cutter grinding. One end of the clamping block 6 is provided with a rubber pad to increase the friction between the clamping block 6 and the milling cutter, ensuring the fixing effect of the milling cutter.

[0024] The clamping cylinder 4 includes a cylinder body 401, a mounting groove 402, a spring 403, and a clamping plate 404.
