SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a high-efficient boring and milling anchor clamps immediately adds under the condition of minimum investment, increases substantially work efficiency and product quality.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the efficient vertical drilling and milling fixture comprises a bottom plate, support plates, positioning plates, a cylinder and a pressing plate, wherein the support plates are vertically fixed on the bottom plate, the front ends of workpieces are fixed on the two sides of the support plates through the positioning plates and are symmetrical relative to the support plates, the rear ends of the workpieces are pressed by the pressing plate, the pressing plate is connected onto the cylinder through a connecting shaft, and two pressing heads symmetrical relative to the connecting shaft are arranged on the pressing plate.
Furthermore, a spherical contact part is arranged at the joint of the connecting shaft and the pressing plate, and the height difference between the workpiece and the workpiece can be offset by connecting the connecting shaft and the spherical surface of the pressing plate; the height difference between two pressure points of the same piece is eliminated by the rotation of the pressure head.
Further, the press head is connected to the press plate through a pin shaft in clearance fit, so that the press head can rotate around the pin shaft. When the workpiece is clamped, if the heights of the workpiece pressing points are different, the pressing head can generate a certain corner, and the workpiece can be pressed by two points.
Furthermore, in order to offset the clamping force more accurately, air paths are designed, and air inlet and air outlet of the air paths of all the cylinders are in the same loop, so that the consistency of air pressure is ensured. The speed regulating valves are arranged on the air inlet branch and the air outlet branch of each air cylinder to ensure that the pressing speeds of the air cylinders are consistent.
The utility model has the advantages that: the workpiece is tightly arranged by utilizing the structural characteristics of the workpiece, so that the milling of a small end face is finished by one-time machining, and the machining time is greatly reduced; in order to arrange the workpieces closely, the number of the cylinders is reduced as much as possible, so that the purpose of reducing the processing stroke is achieved; the workpieces are oppositely arranged, so that the clamping forces are offset, the problem that the support plate is easy to incline is solved, and the product quality is improved; the suspension pressing mechanism solves the problems that the height of the blank surface is changed greatly and the blank surface is not easy to clamp.

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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 3-8, a support plate 4 is vertically fixed on a bottom plate 7, the front ends of workpieces 3 are fixed on two sides of the support plate 4 through positioning plates 5 and are symmetrical relative to the support plate, 8 workpieces 3 are positioned in pairs through the positioning plates 5 on the support plate 4, the rear ends of the workpieces 3 are pressed by a pressing plate 2, the pressing plate 2 is connected to a cylinder 1 through a connecting shaft 10, and two pressing heads 8 symmetrical relative to the connecting shaft 10 are arranged on the pressing plate 2, so that each cylinder 1 simultaneously presses two adjacent workpieces 3.
The thicknesses of the small end faces of the support plate 4, the positioning plate 5 and the workpiece 4 are controlled to be equal to 80 in sum, and the heights of the positioning plate 5 and the support plate 4 are lower than the small end face of the workpiece 4, so that the small end faces of 8 workpieces are machined by one-time feed machining through the phi 100 disc milling, and the machining time is further shortened.
A spherical contact part 11 is arranged at the joint of the connecting shaft 10 and the pressing plate 2, and the height difference between the workpiece and the workpiece can be offset by connecting the connecting shaft 10 and the spherical surface of the pressing plate; the height difference between two pressure points of the same piece is eliminated by the rotation of the pressure head 8.
The ram 8 is connected to the platen 2 by a pin 9 which is a clearance fit so that the ram 8 can rotate about the pin 9. When the workpiece is clamped, if the heights of the workpiece pressing points are different, the pressing head can generate a certain corner, and the workpiece can be pressed by two points.
