Abstract
The utility model relates to mechanical machining technical field and in particular relates to a large-stroke hydraulic self-locking clamping mechanism which essentially comprises a pressure plate, a cylinder sleeve, a piston, a mandril and a cylinder body. The tail part of the pressure plate and the front end of the piston are fabricated to be a 12-degree self-locking structure; a hole on the pressure plate, connected with a pin, is processed to be a flume; a spring is arranged in a guide column on the pressure plate; and the mandril, freely moveable, is installed inside the piston. The large-stroke hydraulic self-locking clamping mechanism has the advantage that the large-stroke hydraulic self-locking clamping mechanism is suitable for a workpiece which requires large compressed cutting force, has a complicated shape and limited spatial room and demands the stroke of the pressure plate to be large. Meanwhile, the clamping mechanism is compact in structure, reliable in clamping, centralized in function and low in cost and can be widely used as a single clamping unit in heavy cutting processes.
Description
Technical field:
The utility model relates to the Machining Technology field, be specially big stroke hydraulic self-locking clamp mechanism.
Background technology:
Mechanical processing industry needs to be equipped with a large amount of hydraulically operated fixtures in process of production on the equipment.Needing to use a large amount of hydraulic jacks, corner cylinder on the hydraulically operated fixture is a kind of forms of anchor clamps with hydraulic jack, and frequency of utilization is higher.The used corner cylinder of anchor clamps mainly relies on import now, its swivelling chute adopts the steel ball helicla flute, and steel ball is fixed on the piston, during the piston motion, steel ball drives piston and moves up and down along the spiral fluted track that designs, and rotates stuck problem but oil cylinder often appears in this structure.This kind corner cylinder stroke is less simultaneously, does not float in the compaction process, and thrust is less, is not suitable for the clamping of large-scale workpiece.
Summary of the invention:
The utility model provides a kind of big stroke hydraulic self-locking clamp mechanism, thereby has overcome the deficiency of existing clamp mechanism.
Technical solution of the present utility model is: big stroke hydraulic self-locking clamp mechanism, mainly form by pressing plate, cylinder sleeve, piston, push rod, cylinder body, pressing plate afterbody and piston nose are made 12 degree self-locking structures, the skewed slot form is processed in the hole that is connected with pin on the pressing plate, in the lead on the pressing plate spring is housed, the while internal piston is equipped with can free-moving push rod.
The beneficial effects of the utility model are that the suitable cutting force that compresses is very big, row shape complexity, and the locus is limited, requires the bigger workpiece of stroke of pressing plate simultaneously again.While this clamp mechanism compact conformation, reliable clamping, function is concentrated, and cost is low, can be used as single clamping unit and obtains more application at heavy cutting.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the utility model structural representation
Among the figure 1, pressing plate, 2, pin, 3, lead, 4, spring, 5, cylinder sleeve, 6, back-up ring, 7, piston, 8, push rod, 9, the cylinder body flange, 10, cylinder body.
The specific embodiment:
In Fig. 1, pressing plate (1) afterbody and piston (7) front end are made 12 degree self-locking structures, pressing plate (1) is gone up the hole that is connected with pin (2) and is processed into the skewed slot form, realize lifting and falling of pressing plate (1), spring (4) is housed in the lead on the pressing plate (3), and the while internal piston is equipped with can free-moving push rod (8).
In the operating process of reality, in the proal process of pressing plate (1), push rod (8) travels forward with the less dynamic pressure plate of trying hard to recommend, realize falling automatically by the skewed slot that is connected with pin (2) simultaneously, the front end of the afterbody of pressing plate and piston (7) is made the self-locking structures of 12 degree, pressing plate is compressed put in place the back to realize self-locking; Spring (4) is equipped with in lead (3) inside, and this structure can realize free floating when playing guiding and pressing plate workpiece pressing hair side, and the structure that piston, pressing plate are formed is contained in the inherent cylinder body of cylinder sleeve (5) slides.When clamp loose, piston and pressing plate self-locking structure unclamp, and push rod drives pressing plate and moves backward, adopt the suitable cutting force that compresses of this mechanism very big, row shape complexity, and the locus is limited, requires the bigger workpiece of stroke of pressing plate simultaneously again.While this clamp mechanism compact conformation, reliable clamping, function is concentrated, and cost is low, can be used as single clamping unit and obtains more application at heavy cutting.
Claims (1)
1. big stroke hydraulic self-locking clamp mechanism, mainly form by pressing plate, cylinder sleeve, piston, push rod, cylinder body, it is characterized in that: pressing plate afterbody and piston nose are made 12 degree self-locking structures, the skewed slot form is processed in the hole that is connected with pin on the pressing plate, in the lead on the pressing plate spring is housed, the while internal piston is equipped with can free-moving push rod.
