Description

Technical Field

[0001] The utility model relates to the technical field of CNC machining, in particular to a quick-changing fixture for CNC machining tools. Background Art

[0002] CNC is the abbreviation of computer numerical control machine tool, which is an automated machine tool controlled by a program. The control system can logically process programs specified by control codes or other symbolic instructions, decode them through a computer, and enable the machine tool to perform the specified actions, and process the blank into semi-finished finished parts through tool cutting.

[0003] Existing technologies using screw fixation, magnetic table fixation, or pressure plate fixation cannot achieve the function of repeated clamping zero point positioning. Each time the workpiece is loaded on the machine, manual calibration and centering are required, which increases the operator's labor intensity and also causes human errors.

[0004] At present, the Chinese utility model with the publication number CN218746270U discloses a zero-point quick mold change fixture for a CNC machining center, including a fixture base, a right-angle positioning block fixedly arranged on the fixture base and corresponding to two adjacent right-angled sides of the workpiece, and an inclined squeezing block adjustably arranged on the fixture base and corresponding to the other two adjacent right-angled sides of the workpiece. The fixture base is provided with positioning holes corresponding to the positioning pins on the workbench. The utility model uses the right-angle positioning edges formed by the two right-angle positioning blocks to level the two horizontal straight lines X and Y, and then uses the inclined squeezing blocks to cooperate with the right-angle positioning blocks from the other two sides to clamp the workpiece. In this way, before batch processing of the same workpiece, it is only necessary to find the coordinates once. Subsequently, it is only necessary to replace the same workpiece and lock it to reprocess it. It can not only reduce the operator's workload, avoid human errors and smooth the cutting, but also achieve high surface finish and processing accuracy of the workpiece. Workpieces of various sizes can be quickly and repeatedly clamped and the processing coordinates will not shift.

[0005] In response to the above problems, the existing patent provides a solution. When the staff replaces the fixture, the staff needs to reach into the CNC machine tool to disassemble and replace the fixture. Due to the limited internal space, it is more troublesome for the staff to disassemble, which wastes a lot of time of the staff and easily causes damage to the staff's hands. Therefore, it is not conducive to the staff to disassemble and replace the fixture. At the same time, waste chips will be generated during the CNC machine tool processing process. These waste chips usually need to be manually cleaned and collected by the staff, thereby increasing the staff's workload and reducing the staff's work efficiency. Manual cleaning can easily lead to incomplete cleaning of waste chips, so it cannot meet the staff's usage needs.

[0006] Therefore, a quick-change fixture for CNC machining tools is proposed. Utility Model Content

After the CNC machine tool processing is completed, the staff starts the electric telescopic rod 501 to drive the cleaning plate 502 to push the waste chips, so that the waste chips fall through the drop port 503 to the inside of the collection box 505 inside the collection box 504. After the CNC machine tool processing is completed, the generated waste chips can be effectively cleaned and collected, so there is no need for the staff to manually clean and collect them, thereby reducing the staff's workload and improving the staff's work efficiency. It also avoids the problem of incomplete waste chip cleaning, so it can meet the staff's usage needs.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
