Abstract
The utility model discloses a hydraulic clamping device of a machine tool workbench, which comprises an oil cylinder, a pin shaft, a pin post, an annular pressing sheet, a fixed support, a press plate, a tension spring and a wedge. The oil cylinder is arranged between the workbench and a sliding seat; the pin shaft is fixed onto the lateral surface of the workbench; the pin post is fixed onto the sliding seat; the annular press sheet is fixed to the lower portion of the workbench; the fixed support is arranged below the annular press sheet; the press plate, the tension spring and the wedge rotate around the pin shaft; one end of the tension spring is connected to the pin post; the other end of the tension spring is connected with the wedge fixedly connected to the end of a piston rod of the oil cylinder; and when the press plate is positioned at a pressing position, one end of the press plate is in pressed fit with the annular press sheet, and the lower surface of the other end of the press plate is attached to the inclined surface of the wedge. The hydraulic clamping device of the machine tool workbench adopting the structure uses the space between the workbench and the sliding seat reasonably, facilitates operation of workers, can ensure reliability of the workbench when in work, can reduce working capacity of installation and maintenance, and increase working efficiency.
Description
Technical field
The utility model relates to lathe, relates in particular to the platen hydraulic clamp.
Background technology
The dividing movement of platen rotation is at present generally driven by ring gear, and Tischarretierungsvorrichtung is generally on four angles of slide and is provided with four clamping points, uses for clamping at the outside of workbench design annulus; And work as workbench by the external toothing driven rotary, then be subjected to other factors restrictions such as structure, space, the clamping device of outside clamping mode can't use, and has to adopt at its clamping device of workbench internal placement the inside clamping mode of existing workbench, be on workbench, to punch, clamping device is installed one by one, has not only been destroyed the integrality of workbench, cause the rigidity of workbench to descend, and installation is inconvenient, maintenance is more difficult, and operating efficiency is lower.
The utility model content
Technical problem to be solved in the utility model is: a kind of platen hydraulic clamp is provided, and this kind platen hydraulic clamp can guarantee the workbench reliability during operation, has reduced the workload of installing and keeping in repair, and increases work efficiency.
Solve this technical problem, the technical solution of the utility model is: a kind of platen hydraulic clamp, it comprises the oil cylinder between workbench and the slide, be fixed in the bearing pin of workbench side, be fixed in the pin on the slide, be fixed in the annular clamping piece of workbench bottom, the hold-down support of annular clamping piece below, pressing plate around the bearing pin rotation, extension spring and voussoir, one end of described extension spring is connected in pin, the other end of extension spring is connected with voussoir, described voussoir is fixed in the oil cylinder piston boom end, when described pressing plate is in compacted position, one end of pressing plate and annular clamping piece pressing, fit in the inclined-plane of pressing plate other end lower surface and voussoir.
Described oil cylinder comprises cylinder body and dismountable oil cylinder cover, and described oil cylinder piston bar passes oil cylinder cover.
The utility model platen hydraulic clamp adopts such structure, reasonably use the space between workbench and the slide, made things convenient for staff's operation, can guarantee the workbench reliability during operation, can reduce the workload of installing and keeping in repair, increase work efficiency.

Structural representation when Fig. 2 is the utility model platen hydraulic clamp relaxation state;
Fig. 3 is a B-B schematic diagram shown in Figure 1;
In Fig. 1, Fig. 2, Fig. 3,1, pin; 2, extension spring; 3, workbench; 4, belt clamp clip; 5, hold-down support; 6, bearing pin; 7, pressing plate; 8, voussoir; 9, oil cylinder piston bar; 10, oil cylinder cover; 11, oil cylinder; 12, slide.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the platen hydraulic clamp comprises the oil cylinder 11 between workbench 3 and the slide 12, be fixed in the bearing pin 6 of workbench 3 sides, be fixed in the pin 1 on the slide 12, be fixed in the annular clamping piece 4 of workbench 3 bottoms, be positioned at the hold-down support 5 of annular clamping piece 4 belows, pressing plate 7 around bearing pin 6 rotations, extension spring 2 and voussoir 8, one end of extension spring 2 is connected in pin 1, the other end of extension spring 2 is connected with voussoir 8, voussoir 8 is fixed in oil cylinder piston bar 9 ends, when pressing plate 7 is in compacted position, one end of pressing plate 7 and annular clamping piece pressing, fit in the inclined-plane of pressing plate 7 other end lower surfaces and voussoir 8.Oil cylinder 11 comprises cylinder body and dismountable oil cylinder cover 10, and described oil cylinder piston bar 9 passes oil cylinder cover 10.Operation principle is: it is flexible that the pressure oil in the oil cylinder 11 promotes oil cylinder piston bar 9 levels, oil cylinder piston bar 9 pulling voussoirs 8 overcome extension spring 2 pulling force and move to the workbench center, driving pressing plate 7 rotates counterclockwise around bearing pin 6, push down the annular clamping piece 4 that is fixed on below the panoramic table until pressing plate 7, thereby evenly, clamping table automatically; During oil cylinder 11 oil returns, extension spring 2 resets by the pulling force of self, moves behind the extension spring 2 pulling voussoirs 8, and pressing plate 7 clockwise rotates around bearing pin 6, and workbench loosens.The utility model platen hydraulic clamp adopts such structure, reasonably used the space between workbench and the slide, made things convenient for staff's operation, can guarantee workbench reliability during operation, security and precision, can reduce the workload of installing and keeping in repair, increase work efficiency.
