Detailed Description

The utility model will be further described with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1-2, a steel anchor clamp comprises a machine tool workbench 1, a pair of heightening blocks 2 are arranged on the machine tool workbench 1, a hydraulic equal dividing head 3 and a disc tailstock 4 are respectively arranged on the heightening blocks 2, a bridge plate 5 is arranged between the hydraulic equal dividing head 3 and the disc tailstock 4, a plurality of chucks 6 are arranged on the bridge plate 5, bearing seats 7 are arranged on the same side of each heightening block 3, a rotating shaft 8 is arranged between the bearing seats 7, a pair of rocker arms 9 and a push rod 10 are arranged on the rotating shaft 8, axial positioning blocks 11 are arranged between the rocker arms 8, a driving cylinder 12 is hinged to the inner side of each heightening block 2, and a piston rod of the driving cylinder 12 is hinged to the push rod 10.

Specifically, the method is divided into three working state flows:

1. when a workpiece is clamped, the axis of the chuck is in a horizontal state, the axial positioning block 11 is installed on the rocker arm 9, the rocker arm 9 is driven by the driving cylinder 12 to move to a horizontal position (see fig. 4), the chuck clamping jaw is in a loosening state, the workpiece is plugged in from the bottom of the chuck at the moment until the end face of the workpiece abuts against the axis positioning block 11, and the workpiece is sequentially loaded;

2. after a workpiece is plugged and positioned, a machining program is started, the electromagnetic valve acts to drive chuck jaws to clamp the workpiece, then the axial positioning block 11 is far away from the workpiece under the action of the driving cylinder 12 (see fig. 5), preparation is made for rotation of the hydraulic equal division head 3, and collision between the chuck 6 and the axial positioning block 11 is avoided in the rotation process;

3. the hydraulic equal dividing head 3 is driven by hydraulic pressure to rotate 90 degrees, the chuck axis is rotated to a vertical processing position (see figure 6), after the rotation to the position, the locking oil cylinder acts, the toothed disc is meshed, the dividing head is locked, the clamp is ready, and the processing program is executed.

In this embodiment, the jaw height of the chuck is adjustable: the jack catch with high and low specifications is matched randomly. A height clamping device is selected according to the length of the machined workpiece for installation, so that the clamping length is ensured, and the clamping stability is improved.

In this embodiment, the clamping diameter is adjustable: the clamping stroke of the clamping jaws on the chuck is 5mm, and when the diameter of a workpiece to be clamped is smaller than or exceeds a clamping range, the positions of the clamping jaws on the chuck are adjusted to be suitable for clamping workpieces with different diameters.

Referring to fig. 3, a plurality of mounting grooves 51 are formed in the surface of the bridge plate 5, a through hole 52 for the steel anchor to pass through is formed in the center of each mounting groove 51, and a ring of positioning spigots 53 are formed outside the through hole 52. When the chuck 6 needs maintenance, in order to operate conveniently, the chuck 6 can be taken off from the bridge plate 5, and the bridge is installed after the maintenance is finished, and on 5, the positioning spigot 53 of the spigot of the bottom plate of the chuck is matched with the positioning spigot 53 of the bridge plate during installation, so that the accuracy of the position of the chuck on the bridge plate is ensured.

In the embodiment, the hydraulic equal dividing head 3 adopts a quartering dividing head, the three-piece toothed disc is hydraulically locked, the circumferential positioning precision is 4 ", and the repeated positioning precision is 2", so that the precision during rotation is improved, namely the machining precision is improved.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
