Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a numerically controlled fraise machine work piece clamping device, including numerically controlled fraise machine platform 1, work piece platform 2, centre gripping adjustment mechanism 6 and grip block 7, work piece platform 2 is installed at the top of numerically controlled fraise machine platform 1, install curb plate 3 on the numerically controlled fraise machine platform 1 of 2 one sides of work piece platform, curb plate 3 is provided with two, two rotate between the curb plate 3 and install two-way screw rod 4, two first swivel nut 5 that two symmetries set up are installed to the screw thread on the two-way screw rod 4, two first swivel nut 5 has grip block 7 through 6 fixed mounting of centre gripping adjustment mechanism, grip block 7 is provided with two, two grip block 7 symmetry sets up in work piece platform 2 both sides, 8 output shafts fixed mounting of servo motor on the one end of two-way screw rod 4 and the curb plate 3.
Centre gripping adjustment mechanism 6 includes regulating plate 61 and adjusting screw 63, regulating plate 61 has been close to one side of grip block 7 and has been seted up adjustment tank 62, adjusting screw 63 is installed to the adjustment tank 62 internal rotation, adjusting screw 63 goes up the cover and establishes and install second swivel nut 64, fixed mounting has grip block 7 on the second swivel nut 64, two equal fixed mounting has rubber pad 71 on one side that grip block 7 is close to mutually, regulating plate 61 and regulation bull stick 65 fixed mounting are passed to adjusting screw 63's one end, it is the setting of Z type structure to adjust bull stick 65, the height that highly is higher than two-way screw rod 4 of work piece platform 2, just two-way screw rod 4 screw thread central symmetry sets up, the bottom fixed mounting of numerical control milling bed platform 1 has support frame 9.
The working principle is as follows: when the clamping device is used, the height of the clamping plates 7 is adjusted according to the size and height of workpieces to be processed in batch, during adjustment, the adjusting rotating rod 65 is rotated, the rotation of the adjusting rotating rod 65 drives the adjusting screw 63 in the adjusting groove 62 to rotate, so that the second screw sleeve 64 moves up and down on the adjusting screw 63 to drive the clamping plates 7 to lift up and down on the adjusting plate 61, namely, the height of the two clamping plates 7 is effectively and flexibly adjusted, the two clamping plates 7 are suitable for stably clamping the workpieces with different heights, when a workpiece with larger height is clamped, the clamping plates 7 move up to realize the middle clamping of the workpiece, the instability of bottom clamping is avoided, meanwhile, the clamping plates 7 with large width are suitable for clamping the workpieces with smaller height through the reduction of the height of the clamping plates 7, the clamping plates 7 with large width are prevented from being higher than the workpiece to block the processing of the corners of the workpieces by the milling machine, the workpieces to be processed in batch by the numerical control milling, under the drive of two-way screw rod 4, two first swivel nuts 5 are close to each other for two grip blocks 7 are close to the work piece centre gripping on the work piece platform 2, drive two-way screw rod 4 again after the processing and rotate, two first swivel nuts 5 keep away from the motion each other, the centre gripping is loosened, two-way screw rod 4 driven centre gripping, dismantle easy operation, it is stable, realize numerically controlled fraise machine work piece centre gripping fixed processing, the efficiency and the product quality of processing are improved, and fixed mounting's rubber pad 71 carries out the centre gripping protection to the work piece on grip block 7, greatly reduce the centre gripping and lead to the fact the double-layered trace loss to the work piece.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
