Technical Field

[0001] The utility model relates to the technical field of workpiece fixing devices, in particular to a workpiece fixing device for a vertical machining center machine tool. Background Art

[0002] A machining center is a highly automated, multifunctional CNC machine tool equipped with a tool magazine and automatic tool changer. A vertical machining center is one in which the spindle axis is perpendicular to the worktable. It is primarily suitable for machining complex parts such as plates, discs, molds, and small housings. A vertical machining center can perform milling, boring, drilling, tapping, and thread cutting. Compared to horizontal machining centers, it has a simpler structure, smaller footprint, and lower price. A workpiece fixture is a component of a vertical machining center that is used to secure the workpiece in place.

[0003] At present, the workpiece fixing device is usually composed of a fixed plate supporting the workpiece and a strip hollow groove opened on the fixed plate, and the strip hollow groove is used to limit the position of the workpiece on the fixed plate; although the strip hollow groove can limit the position of the workpiece, the debris generated by the workpiece during processing will accumulate in the strip hollow groove. If the debris in the strip hollow groove accumulates too much, it will cause the strip hollow groove to be blocked, which will affect the problem that the subsequent workpiece needs to be connected to the fixed plate through the strip hollow groove.

[0004] Therefore, we proposed a workpiece fixing device for vertical machining center machine tools to solve the above problems. Utility Model Content

[0028] A cleaning push block 6 is fixedly provided on the movable plate 50, one end of which is inserted into the connecting groove 3 on the workpiece fixing plate 2, and a slider 7 is fixedly provided on the lower end surface of the movable plate 50, which is slidably provided in the slide groove 5 on the connecting plate 4, and a threaded rod 8 is rotatably provided in the slide groove 5, and the slider 7 in the slide groove 5 is sleeved on the threaded rod 8 in the slide groove 5;

[0029] A fixing frame 9 is fixedly provided on one end face of the guide rail 1, a servo motor 10 is fixedly provided on the fixing frame 9, a first transmission member 11 is rotatably provided inside the fixing frame 9, the first transmission member 11 is connected to two second transmission members 12 through a belt, and the two second transmission members 12 are respectively docked with one end of the two threaded rods 8.

[0030] By setting up the cleaning component, the processing debris in the connecting groove 3 on the workpiece fixing plate 2 can be cleaned, so as to avoid the accumulation of processing debris in the connecting groove 3. The accumulated processing debris will cause blockage of the connecting groove 3, making it inconvenient for subsequent processing parts to be connected to the workpiece fixing plate 2 through the connecting groove 3.

[0031] The upper end surface of the guide rail 1 is provided with a socket 13 , and there are four sockets 13 arranged in a rectangular shape. First locking blocks 14 are fixedly provided at the four corners of the lower end surface of the workpiece fixing plate 2 , and the four first locking blocks 14 are respectively inserted into the four sockets 13 .

[0032] The socket 13 is provided with a receiving groove 15, in which a second locking block 16 is rotatably mounted. The locking catch of the second locking block 16 interlocks with the locking catch of the first locking block 14. The arrangement of the second locking block 16 and the first locking block 14 facilitates fixing the workpiece fixing plate 2 to the guide rail 1.

[0033] A compression spring 17 is fixedly disposed in the receiving groove 15, one end of which is fixedly connected to the second locking block 16. The provision of the compression spring 17 not only facilitates restoring the second locking block 16 to its original position after rotation, but also allows the lock catch of the second locking block 16 to be positioned against the first locking block 14, thereby locking the lock catch of the second locking block 16 with the lock catch of the first locking block 14.

[0034] The second locking block 16 is provided with a guide groove 18, in which a push rod 19 is slidably disposed. One end of the push rod 19 passes through the guide rail 1, and a pressing block 20 is fixedly disposed on the other end of the push rod 19 passing through the guide rail 1. The guide groove 18 serves to guide the sliding movement of the push rod 19 on the second locking block 16.

[0035] A coil spring 21 is fixedly mounted on the pressing block 20 , and one end of the coil spring 21 is fixedly connected to the guide rail 1 .

[0036] The arrangement of the first locking block 14 , the second locking block 16 , the extrusion spring 17 , the push rod 19 , the pressing block 20 , and the coil spring 21 makes it easier and more convenient to disassemble and install the workpiece fixing plate 2 on the guide rail 1 .

[0037] This utility works as follows:

[0038] When the workpiece fixing plate 2 needs to be cleaned, the servo motor 10 is started. The start of the servo motor 10 drives the first transmission member 11 to rotate. The first transmission member 11 drives the second transmission member 12 to rotate through the belt. The rotation of the second transmission member 12 drives the threaded rod 8 to rotate. The rotation of the threaded rod 8 drives the movable plate 50 to move toward the workpiece fixing plate 2. The movement of the workpiece fixing plate 2 drives the cleaning push block 6. The movement of the cleaning push block 6 will push out the processing debris in the connecting groove 3 on the workpiece fixing plate 2. When the processing debris in the connecting groove 3 is pushed out, the servo motor 10 is started in the reverse direction to restore the cleaning push block 6 to its original position. When the workpiece fixing plate 2 needs to be replaced, the workpiece fixing plate 2 is moved to the workpiece fixing plate 2. The pressing block 20 is pressed in the direction of the fixed plate 2. The pressing block 20 is subjected to force to push the second locking block 16 to rotate in the accommodating groove 15. The rotation of the second locking block 16 will cause the lock catch of the second locking block 16 to be staggered with the lock catch of the first locking block 14. At this time, the workpiece fixing plate 2 is lifted upward to pull the first locking block 14 on the workpiece fixing plate 2 out of the socket 13 on the workpiece fixing plate 2. Then, the new workpiece fixing plate 2 is inserted into the socket 13 on the guide rail 1 through the first locking block 14. The first locking block 14 inserted in the socket 13 will be staggered with the second locking block 16, and the staggered second locking block 16 will cause the lock catch on the second locking block 16 to be locked with the lock catch on the first locking block 14 under the thrust of the extrusion spring 17, so that the replacement of the workpiece fixing plate 2 can be completed.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
