The application provides a multistation flexible clamp cooperation numerical control machining center, vice, locator use. In actual operation, the vice is placed at the center of a workbench of a machining center and is pressed and fixed by a pressing plate; installing a positioner on the side surface of the vice; the jig body 11 is placed on the table. Then, the two positioning blocks 2 and the spring 3 are combined and placed in the same positioning groove 11 together. Then, the assembled multi-station flexible fixture is integrally placed in a vice, so that one surface (i.e. the first clamping surface 13) in the width direction of the fixture body 1 needs to be attached to a fixed jaw of the vice, and one surface in the length direction needs to be attached to a positioner. Then an operator controls the vice wrench to slowly rotate to push the movable jaw of the vice to move, in the process that the two jaws of the vice are continuously tightened, the movable jaw pushes the workpiece 4 and the positioning block 2 to be continuously close to each other, the positioning block 2 transmits force to the spring 3, after the other surface (namely, the second clamping surface 13) in the width direction of the clamp body 1 is tightly pressed on the movable jaw, the spring 3 in a compression state tightly presses the positioning block 2 on the movable jaw of the vice by using elastic force.
Firstly, because locating hole 21 and work piece 4 clearance fit of locating piece 2, the lateral wall of the two is in laminating state roughly, consequently, compares the mode that the work piece 4 was directly held to the vice among the prior art, has reduced the impaired risk of work piece 4.
Secondly, because the distance of keeping silent of vice is certain, and controllable, and locating piece 2 adopts flexible location mode, fixes a position locating piece 2 through elastic component and vice jointly promptly for locating piece 2 can hug closely the surface at the vice jaw of vice at last. In actual processing, the multi-station flexible clamp can be used for multiple times and can clamp workpieces 4 of different batches. After the first clamping is completed, the machining center can automatically detect the position of the inner hole of the workpiece 4 through the equipped detection equipment and record the position. The operator can keep the position of the fixed jaw of the vise constant during the subsequent processing of other batches of workpieces 4, thereby positioning each batch of workpieces 4 in the same position. Therefore, even if repeated clamping is carried out, and even if errors exist in the actual sizes of the positioning blocks 2 arranged on the clamp body 1, the center distances of the workpieces 4 after clamping are always the same, so that the problems that the sizes of the positioning blocks 2 are inconsistent and the sizes of the center distances of the positioning holes 21 are inconsistent are solved, and the consistency of the machining sizes of the workpieces 4 is ensured. Therefore, the inner hole positions of the first batch of workpieces 4 can be detected only during machining, and the later batches of workpieces 4 do not need to be repeatedly aligned, so that the problems of repeated alignment and low repeated positioning precision during clamping at each time are solved, the alignment difficulty is reduced, and the alignment efficiency is improved.
Thirdly, as the multi-station flexible fixture is provided with at least two positioning blocks 2, for example, in the scheme shown in fig. 1, the multi-station flexible fixture can finish the processing of 6 workpieces 4 by one-time clamping without independently positioning each workpiece 4, thereby effectively reducing the clamping time, reducing the labor intensity of workers and further greatly reducing the total processing time.
Further, for the circular workpiece 4 with the flat surface, the circumferential direction of the workpiece 4 has a C-shaped arc-shaped side wall and a flat surface, in a preferred embodiment provided by the present application, the side wall of the positioning hole 21 includes a C-shaped positioning surface 25 for clearance-fitting with the outer circle of the workpiece 4, the C-shaped positioning surface 25 has two parallel edges 26 distributed at a preset distance, and when the clamping surface 13 is clamped by the vise, the edges 26 contact with the movable jaw of the vise, so that the vise pushes the flat surface of the workpiece 4 to a state coplanar with the clamping surface 13.
Specifically, the side wall of the positioning block 2, which is used for contacting with a vice, is a clamping side wall 24, the clamping side wall 24 is a planar structure parallel to the clamping surface 13, and the positioning hole 21 is formed by inward recessing of the clamping side wall 24.
In practice, when assembling the positioning block 2 and the workpiece 4, the workpiece 4 is placed in the positioning hole 21 of the positioning block 2, and it should be noted that the flat surface of the outer circle of the workpiece 4 needs to be exposed and substantially parallel to the clamping sidewall 24. When the movable jaw of the vice is controlled to move, the workpiece 4 can be automatically leveled after being lightly touched, and after the movable jaw moves in place, the elastic piece presses the workpiece 4 and the positioning block 2 on the surface of the movable jaw together. This is more remarkable in processing advantage for ensuring stability of processing quality and high efficiency of processing of the large-batch workpieces 4.
Optionally, in practical use, because the specifications of the workpieces 4 are different, the positioning holes 21 can be set to be stepped holes capable of accommodating the workpieces 4 of different specifications, so that the workpieces 4 of different specifications can be machined.
Optionally, in order to facilitate installation of the spring 3, the positioning block 2 may further include an installation hole 23, an end of the elastic member is disposed in the installation hole 23, and a gap between the installation hole 23 and the large diameter of the spring 3 is within 1 mm. In order to prevent the center of gravity of the positioning block 2 from being unstable due to the resilience of the spring 3, the mounting hole 23 should be formed at the center of the end surface of the positioning block 2.
Optionally, in order to ensure that the positioning block 2 slides freely in the positioning groove 11 and does not move in the vertical direction, corresponding limiting structures may be disposed in the positioning block 2 and the positioning groove 11, for example, the bottom of the positioning block 2 is provided with a limiting protrusion 22, the bottom of the positioning groove 11 is provided with a limiting groove 12, the limiting protrusion 22 is in clearance fit with the limiting groove 12, and the clearance is controlled within 0.02 mm. The limiting protrusion 22 and the limiting groove 12 are beneficial to accurate positioning and movement of the positioning block 2, and can play a role in guiding during sliding and also play a role in limiting the positioning block 2 from moving up and down. In practical use, the cross section of the positioning groove 11 is preferably in a T shape, and at this time, the positioning groove 11 includes an upper groove body and a lower groove body which are distributed up and down, and the width of the upper groove body is smaller than that of the lower groove body. In order to prevent the intersection right angle of the upper groove body and the lower groove body from interfering with the root of the limiting protrusion 22, a chamfer C1 at the intersection right angle of the upper groove body and the lower groove body is preferred.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The multi-station flexible clamp provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
