[0001] The utility model relates to the technical field of mechanical processing, in particular to a numerically controlled milling and boring machine for processing double-headed studs. Background Art

[0002] When processing double-headed studs on a CNC milling and boring machine, a pad plate is usually installed on the top of the moving plate of the milling and boring machine. A clamping device is placed on the top of the pad plate to clamp the studs. Two studs are placed symmetrically on both sides of the clamping device, and thread processing is performed on one end of the studs at the same time.

[0003] When the clamping device is in use, the lower clamp is fixedly installed on the raising plate, and the upper clamp is fixedly clamped on the stud by inserting the screw and squeezing the upper clamp with the nut. Therefore, when the stud is turned and the thread on the other end is processed, the nut needs to be removed in the direction away from the upper clamp, and the upper clamp needs to be moved away from the screw. The upper clamp needs to be placed on a movable plate or other position before the stud can be moved. After the stud is changed, the upper clamp needs to be moved back to the top of the lower clamp, and this process is repeated. When a large number of double-headed studs are processed, a lot of workers' physical strength will be consumed, which is not convenient for the use of the clamping device. Utility Model Content

[0022] Furthermore, the movable plate of the existing CNC milling and boring machine is fixedly connected to the movable telescopic device inside the milling and boring machine, so that the movable plate 1 can be driven to move left and right through the movable telescopic device. A plurality of grooves are evenly spaced at the top of the movable plate 1, and the grooves are in an inverted T shape. The pad plate 5 is fixedly connected to the movable plate 1 through a pressing device provided on the movable plate 1. The pressing device can be composed of a pressing plate, a screw and a nut. The side of the pad plate 5 is pressed and fixed by the pressing plate. The upper clamp 4 and the lower clamp 3 have clamping grooves for clamping the processing studs 2 at opposite ends respectively, and the clamping grooves are isosceles trapezoids. The lower clamp 3 is fixedly connected to the top of the pad plate 5 by bolts.

[0023] Specifically, a groove is provided at the top of the movable plate 1 for inserting the threaded rod 71, and a positioning nut 74 is threadedly sleeved on the outer wall at the bottom of the threaded rod 71 for fixing the position of the threaded rod 71. The two ends of the connecting plate 62 are respectively fixedly connected to one side of the rotating cylinder 61 and one side of the upper clamp 4. The bottom end of the connecting plate 62 is fixedly connected to a reinforcing member for strengthening the strength of the connecting plate 62. The reinforcing member includes a reinforcing rib 63, the top of the reinforcing rib 63 is fixedly connected to the top of the connecting plate 62, and the two ends of the reinforcing rib 63 are respectively fixedly connected to one side of the rotating cylinder 61 and one side of the upper clamp 4.

A threaded groove is provided at the top of the support block 72, and the support block 72 is threadedly sleeved on the outer wall of the threaded rod 71. The vertical cross-section of the support block 72 is T-shaped.

[0024] Furthermore, the threaded rod 71 is composed of a screw and a nut. The threaded rod 71 is in an inverted T shape. The size of the bottom of the threaded rod 71 corresponds to the size of the groove. By rotating the positioning nut 74, the nut is continuously lifted and fits with the top of the inner wall of the groove, thereby realizing the clamping of the nut and the positioning nut 74 with the top of the movable plate 1, and fixing the position of the threaded rod 71 to ensure that the position of the upper clamp 4 is directly above the lower clamp 3. The two ends of the connecting plate 62 are fixedly connected to the outer wall of the rotating cylinder 61 and the side wall of the upper clamp 4 by welding, and the right-angle sides of the reinforcing rib 63 are respectively connected to the connecting plate 62, the rotating cylinder 61, and the upper clamp 4 The contact parts are connected by welding.

At this time, when the stud 2 needs to be processed, by rotating the upper clamp 4, the upper clamp 4 drives the rotating cylinder 61 to rotate through the connecting plate 62, so that the lower clamp 3 and the upper clamp 4 are opened, the processing stud 2 is placed, and then the upper clamp 4 is rotated back to the top of the lower clamp 3. When the upper clamp 4 is lifted due to the height of the processing stud 2, the support block 72 is rotated to make the support The top of block 72 fits with the bottom of rotating cylinder 61, and the pressing nut 73 is rotated at this time to make the pressing nut 73 continuously squeeze the rotating cylinder 61, so that the rotating cylinder 61 cannot rotate under the action of the supporting block 72 and the pressing nut 73, thereby achieving the fixation of the upper clamp 4. When the position of the processing stud 2 needs to be changed, the upper clamp 4 can be lifted and rotated by rotating the pressing nut 73 away from the rotating cylinder 61 to move the processing stud 2. In this way, when the upper clamp 4 is moved, the moving distance of the upper clamp 4 is short, which saves the time and physical strength of the staff in disassembling and installing the upper clamp 4.
