Abstract
The utility model relates to a clamping cylinder and particularly relates to a lever type clamping cylinder. The technical scheme includes that the cylinder comprises a cylinder body, a cylinder cover, a lever, a bolt, an upper spherical washer, a lower spherical washer, a disk spring, a piston rod, a cushion block and a piston, wherein the piston rod is fixed inside the cylinder body, the piston is arranged at the top of the piston rod, the lever is connected to the bottom of the piston rod horizontally, the outer end of the lever is connected with the bolt, the upper spherical washer and the lower spherical washer are arranged between the lever and the bolt, the lever can rotate round the upper spherical washer and the lower spherical washer, the disk spring is fixed to the inside of the cylinder body and the cylinder cover is arranged at the top of the cylinder body. The cylinder has the advantages that the structure is simple, the cost is low, a lever mechanism can enlarge the prior small clamping force of the disk spring, requirements for clamping force of the clamping cylinder are met and the loosening force of the cylinder is not increased.
Description
Technical field
The utility model relates to a kind of clamping cylinder, particularly a kind of lever type clamping oil cylinder.
Background technique
Vertical lathe, the moving beam of large-sized gantry milling-boring machine all needs to adopt fastening device to clamp adding, to guarantee machining accuracy man-hour.Fastening device is generally the clamping cylinder of hydraulic clamp or the clamping cylinder that dish spring clamping hydraulic unclamps.The clamping cylinder of hydraulic clamp need be considered the pressurize under the powering-off state, needs the configuration accumulator, and hydraulic system is required height, and cost is higher.The clamping cylinder that the dish spring clamps adopts the dish spring that clamping force is provided, and is subject to the Dimensions of dish spring, and the clamping force that can provide is less.Needing in the situation of larger clamping force, needing to increase the quantity of using oil cylinder.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of lever type clamping oil cylinder is provided, and simple in structure, cost is low.
Its technological scheme is: be comprised of cylinder body, oil cylinder cover, lever, bolt, upper spherical washer, lower peripheral surface packing ring, dish spring, piston rod, cushion block, piston, the inside fixed piston rod of cylinder body, the top of piston rod is provided with piston, the bottom level of piston rod connects lever, the outer end connecting bolt of lever, be provided with spherical washer and lower peripheral surface packing ring between lever and the bolt, lever can rotate around upper spherical washer and lower peripheral surface packing ring, the dish spring is fixed on the inside of cylinder body, the top of cylinder body is provided with oil cylinder cover, and the end of lever is provided with cushion block.
The upper end portion of above-mentioned lever is provided with cushion block.
The beneficial effects of the utility model are: simple in structure, cost is low, is beneficial to leverage original very less dish spring clamping force is amplified, and to satisfy the clamping force requirement of clamping cylinder, does not increase the Song Kali of oil cylinder simultaneously.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the upper figure: cylinder body 1, oil cylinder cover 2, lever 3, bolt 4, upper spherical washer 5, lower peripheral surface packing ring 6, dish spring 7, piston rod 8, cushion block 9, piston 10.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model is by cylinder body 1, oil cylinder cover 2, lever 3, bolt 4, upper spherical washer 5, lower peripheral surface packing ring 6, dish spring 7, piston rod 8, cushion block 9, piston 10 forms, the inside fixed piston rod 8 of cylinder body 1, the top of piston rod 8 is provided with piston 10, the bottom level of piston rod 8 connects lever 3, the outer end connecting bolt 4 of lever 3, be provided with spherical washer 5 and lower peripheral surface packing ring 6 between lever 3 and the bolt 4, lever 3 can rotate around upper spherical washer 5 and lower peripheral surface packing ring 6, dish spring 7 is fixed on the inside of cylinder body 1, the top of cylinder body 1 is provided with oil cylinder cover 2, and the upper end portion of lever 3 is provided with cushion block 9.
Use the utility model, in the situation that does not increase the cylinder sizes specification, utilize leverage, amplify the clamping force of belleville spring, to satisfy the requirement that clamps.Anticipate as shown, lever 3 forms a fulcrum by bolt 4 and upper spherical washer 5, lower peripheral surface packing ring 6, dish spring 7 is contained in the fixed oil cylinder body 1, utilize the downward push piston bar 8 of deformation force of self, piston rod 8 is threaded connection with lever 3, promotes lever 3 left ends and moves down, because the existence of fulcrum, lever 3 right-hand members move upward, and make the cushion block 9 that is installed in lever 3 terminations produce clamping force upwards.When needs unclamp, injection liquid force feed in the Seal cage of piston 10 lower ends, piston 10 moves up under the effect of hydraulic coupling, drives the piston rod 8 compact disc spring 7 that moves up, thereby cancels the clamping force of oil cylinder.Utilize lever principle, can adjust lever augmented ratio by changing the position of bolt 4 on lever 3, can realize that the dish spring clamping force about 2-8 is doubly amplified.
