Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings.
[0028] Please see Figure 1-4 As shown, this embodiment provides a universal fixture for clamping CNC grinding machines, including a base 1. A dust-collecting rotating assembly 2 is fixedly installed on the inner wall of the bottom of the base 1, with a portion of the dust-collecting rotating assembly 2 located above the base 1. A vertical plate 3 is fixedly installed on the top of the base 1, which can fix an electric push rod 4, so that the electric push rod 4 is placed at a certain height. An electric push rod 4 is fixedly installed on one side of the vertical plate 3, and an adjustable clamping assembly 5 is fixedly installed on the other end of the electric push rod 4. CNC grinding machine interfaces 6 are fixedly installed on both sides of the base 1, which can connect the base 1 and the CNC grinding machine.
[0029] One application of this embodiment is as follows: the part to be ground is placed manually on top of the dust-collecting rotating assembly 2. The dust-collecting rotating assembly 2 can not only adjust the position of the part to facilitate grinding at different positions, but also adjust the adjustable clamping assembly 5 according to the shape of the part to stably clamp irregularly shaped parts. The extension of the electric push rod 4 can drive the adjustable clamping assembly 5 to move, which is convenient for clamping parts of different sizes and improves the applicability of the fixture. During grinding, the dust-collecting rotating assembly 2 can also absorb the waste generated during processing, reducing environmental pollution.
[0030] The vacuum-type rotating assembly 2 includes a rotating motor 201 and a placement tray 202. The bottom of the rotating motor 201 is fixedly mounted on the inner wall of the bottom of the base 1. The bottom of the placement tray 202 is fixed on the output shaft of the rotating motor 201. The placement tray 202 is located above the base 1 and has an opening 203. A support column 204 is fixed to the inner wall of the bottom of the base 1, which supports the vacuum cleaner frame 205. The other end of the support column 204 is fixed to the vacuum cleaner frame 205, which is located on the placement tray 202. Below the opening 203, the top of the vacuum cleaner frame 205 contacts the inner wall of the top of the base 1. A connecting pipe 206 is fixed to the bottom of the vacuum cleaner frame 205. The connecting pipe 206 can connect the vacuum cleaner frame 205 and the vacuum cleaner 207 together. The vacuum cleaner 207 is fixedly installed at the other end of the connecting pipe 206. The bottom of the vacuum cleaner 207 is fixedly installed on the inner wall of the bottom of the base 1. The vacuum cleaner 207 consists of a vacuum box and an exhaust fan. One side of the exhaust fan is located on the outside of the base 1 to facilitate the exhaust of the filtered air.
[0031] In this embodiment, the rotating motor 201 drives the placement tray 202 to rotate, allowing adjustment of the position of the parts placed on top of the placement tray 202. This facilitates grinding at different positions of the parts. Simultaneously, the vacuum cleaner 207 extracts air from the vacuum cleaner frame 205 and the top of the placement tray 202, thereby processing the waste generated during grinding on the top of the placement tray 202. The waste falls into the vacuum cleaner 207 through the vacuum cleaner frame 205 and the connecting pipe 206, reducing air pollution caused by grinding.
[0032] The adjustable clamping assembly 5 includes a fixed frame 501 and a mounting shaft 502. The fixed frame 501 is fixedly mounted on one side of the electric push rod 4 and the mounting shaft 502 is rotatably mounted on the inner side walls of the fixed frame 501. The mounting shaft 502 can fix and adjust the mounting block 503. The mounting block 503 is fixed on the outer side of the mounting shaft 502. The mounting block 503 is provided with a socket. The first rubber clamp 504 and the second rubber clamp 505 are fixedly mounted on both sides of the mounting block 503, respectively. A spring 506 is fixed on one side wall of the fixed frame 501. A pull bracket 507 is fixed on the other end of the spring 506. A plug rod 508 is fixed on one side of the pull bracket 507. The other end of the plug rod 508 is engaged in the socket, which improves the stability of the mounting block 503.
[0033] In this embodiment, when the pull bracket 507 is pulled manually, the spring 506 is in a stretched state. The spring 506 has the ability to return to its original state, and the insertion rod 508 separates from the mounting block 503. Then, by rotating the mounting block 503, the positions of the first rubber clamp 504 and the second rubber clamp 505 can be adjusted, which facilitates clamping parts of different shapes and improves the applicability of the clamp. After the adjustment is completed, the pull bracket 507 is released. Under the action of the spring 506, the other end of the insertion rod 508 can move into the insertion hole, so that the mounting block 503 can be fixed. The adjustment process is simple and easy to operate.
[0034] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
