Abstract
A hydraulic fastener for a vacuum furnace comprises a fastener fixing seat, a fastening handle, a triangular connecting rod and a hydraulic cylinder. The fastener fixing seat is fixed on the outer wall of the vacuum furnace, a fastener which can be compressed on a furnace cover of the vacuum furnace is arranged at one end of the fastening handle, the other end of the fastening handle is connected on the fastener fixing seat through a second shaft A2, one end point of the triangular connecting rod is connected on the fastener fixing seat through a first shaft A1 while a second end point of the same is connected with one end of a connecting rod through a fourth shaft A4, the other end of the connecting rod is connected on the fastening handle through a third shaft A3, two ends of the hydraulic cylinder are movably connected with the fastener fixing seat and a third end point of the triangular connecting rod respectively, and the fastener fixing seat, the triangular connecting rod, the connecting rod and the fastening handle form a rocking handle four-rod mechanism to enable the fastening handle to swing around the second shaft A2 when the hydraulic cylinder actuates. By adopting the four-rod mechanism, a relationship of size interlocking of a crank of the four-rod mechanism and a rocker rod is utilized for locking, and the hydraulic cylinder is adopted as driving power of the fastener, and the hydraulic fastener is simple to manufacture, strong in clamping force and capable of meeting automatic clamping requirements of round and square furnace-profile furnace covers.
Description
Technical field
The utility model relates to a kind of vacuum furnace hydraulic pressure fastener.
Background technique
Connection, the locking usual way of vacuum furnace bell mainly contain: bolt connection, C clamp, three kinds of modes of turn buckle, wherein bolt and C clamp are hand-operated clamping mode.Turn buckle (structure and household pressure-cooker pot cover locking mechanism are similar) conventionally adopts motor, cylinder or Driven by Hydraulic Cylinder thereby can realize auto lock.Hand-operated clamping fastener structures simpler production cost is low, is applicable to mini-plant.Turn buckle is that a kind of automatic structure is applicable to large-scale, cylindrical device, but fabricating cost is high.
Model utility content
The purpose of this utility model is to provide a kind of vacuum furnace hydraulic pressure fastener simple, that chucking power strong, can be satisfied with circular and the Automatic-clamping of square type of furnace bell requires of making for the deficiencies in the prior art.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of vacuum furnace hydraulic pressure fastener, comprise fastener fixed base, Button Handle, triangular coupling rod and oil hydraulic cylinder, described fastener fixed base is fixed on vacuum furnace outer wall, one end of described Button Handle is provided with the fastener that can be pressed on vacuum furnace bell, the other end is connected on described fastener fixed base by the second axle A2, an end points of described triangular coupling rod is connected on described fastener fixed base by the first axle A1, second end points of described triangular coupling rod is connected with one end of connecting rod by the 4th axle A4, the other end of described connecting rod is connected on described Button Handle by the 3rd axle A3, the two ends of described oil hydraulic cylinder are flexibly connected with the 3rd end points of described fastener fixed base and described triangular coupling rod respectively, described fastener fixed base and triangular coupling rod, when connecting rod and rocking handle fourbar linkage of Button Handle composition make described oil hydraulic cylinder action, described Button Handle swings around the second axle A2.
Described the first axle (A1) is A1A2 to the distance between the second axle (A2), described the second axle (A2) is A2A3 to the distance between the 3rd axle (A3), described A1A2=A2A3, described the first axle (A1) is A1A4 to the distance between the 4th axle (A4), described the 3rd axle (A3) is A3A4 to the distance between the 4th axle (A4), described in
Owing to adopting said structure, the utility model adopts a fourbar linkage, utilize the relation of fourbar linkage crank and rocking bar size interlocking to lock, fastener adopts oil hydraulic cylinder as driving power, make simple, chucking power is strong, can be satisfied with the Automatic-clamping requirement of circular and square type of furnace bell.
Brief description of the drawings
Fig. 1 is the plan view of the utility model at vacuum furnace bell closed state.
Fig. 2 is the plan view of the utility model in vacuum furnace bell opening state.
Fig. 3 is that the utility model is arranged on the structural representation in vacuum furnace body.
Embodiment
Below in conjunction with accompanying drawing, further describe the embodiment of this patent.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of vacuum furnace hydraulic pressure fastener, comprise fastener fixed base 2, Button Handle 3, triangular coupling rod 4 and oil hydraulic cylinder 1, described fastener fixed base 2 is fixed on vacuum furnace 6 outer walls, one end of described Button Handle 3 is provided with the fastener that can be pressed on vacuum furnace bell 5, the other end is connected on described fastener fixed base by the second axle A2, fastener comprises with externally threaded screw rod and is arranged on the nut on screw rod, described screw rod spinning is in Button Handle 3 ends, stretch out the length of Button Handle by nut adjusting screw rod, thereby regulate the compaction degree between vacuum furnace bell, an end points of described triangular coupling rod 4 is connected on described fastener fixed base 2 by the first axle A1, second end points of described triangular coupling rod is connected with one end of connecting rod 41 by the 4th axle A4, the other end of described connecting rod 41 is connected on described Button Handle 3 by the 3rd axle A3, the two ends of described oil hydraulic cylinder 1 are flexibly connected with the 3rd end points of described fastener fixed base 2 and described triangular coupling rod 4 respectively, described fastener fixed base 2 and triangular coupling rod 4, when connecting rod 41 and Button Handle 3 form a rocking handle fourbar linkage described oil hydraulic cylinder 1 are moved, described Button Handle 3 swings around the second axle A2.As shown in Figure 1, 2, the distance between distance=the second axle A2 and the 3rd axle A3 between the first axle A1 and the second axle A2; Distance between distance=three axle A3 and the 4th axle A4 between the first axle A1 and the 4th axle A4
the doubly distance between the first axle A1 and the second axle A2.
As shown in Figure 1, H0 represents that maximum can lock thickness, when locking thickness < H0, can, by regulating adjusting bolt adjust, eliminate locking gap.
Locking principle: when locking, oil hydraulic cylinder 1 promotes triangular coupling rod 4, drives Button Handle 3 closures, and Button Handle 3 position that is up to the standard is maximum fastening position, now hinge point A1, the A3 of four bars, A4 point-blank, fastening fastening.Hinge point A1, A2, A3 are a right-angled triangle and distribute, the now self-locking of force direction formation downwards of Button Handle.
