Description
Technical field
The utility model relates to the auxiliary clamp of machine components processing, particularly needs the car hydraulically operated fixture to opposite face clamping.
Background technology
Along with enterprise constantly develops, the application of a large amount of NC postprocessing process equipment and specialized carrying out of producing in enormous quantities, existing frock clamp is constantly brought forth new ideas and improvement.The developing direction of frock clamp abandons the frock clamp of highly energy-consuming in the past, high consumptive material, high labour intensity and poor efficiency, and positive searching is saved energy and reduce the cost, the Novel fixture that uses manpower and material resources sparingly.
In turnery processing for GPC4 series gear pump protecgulum, whole employing is installed by the mode of craft and bolt clip plate, production efficiency is lower, labor strength is large, is difficult to the demand meeting the large production of modernization, has seriously fettered the production capacity of enterprise, and for needing when machining gears pump protecgulum, two parallel end faces are clamped simultaneously now, and require that workpiece can not produce the changing of the relative positions, in turnery processing, make merely the clamping force clamping uncontrollable device needs by hand.
Utility model content
The purpose of this utility model is to provide a kind of fixture that can be used in gear pump protecgulum lathe process.
In order to solve the problem, the lathe hydraulic fixture that the utility model provides, comprise hydraulic pressure end cap, bidirectional piston, first hydraulic cylinder, second hydraulic cylinder and moveable platen, it is the U-shaped chamber of indent above described moveable platen, bidirectional piston and indent U-shaped cavity wall are slidably matched, bidirectional piston upper part indent, and edge is fixedly connected with hydraulic pressure end cap and forms described first hydraulic cylinder, bidirectional piston lower part and moveable platen form described second hydraulic cylinder, described first hydraulic cylinder and the second hydraulic cylinder communicate, former dynamic piston is provided with in described first hydraulic cylinder, first hydraulic cylinder is divided into first cylinder and second cylinder by described former dynamic piston, first cylinder described is communicated with hydraulic power source, second cylinder described is communicated with the second hydraulic cylinder, offset below described moveable platen and be provided with upper gripper jaw, it is pitch brace below described bidirectional piston, the lower jaw relative with upper gripper jaw is fixedly connected with below described pitch brace.
The lathe hydraulic fixture of this programme when in use, in second cylinder of the second hydraulic cylinder and the first hydraulic cylinder, be full of hydraulic oil in advance, first cylinder feed flow of first hydraulic cylinder of this fixture is given by hydraulic power source, now piston is moved to the second hydraulic cylinder activity in source, because the hydraulic fluid pressure in second cylinder of the first hydraulic cylinder increases, hydraulic oil is flowed to continue to flow in the second hydraulic cylinder, the hydraulic oil of the second hydraulic cylinder upwards provides pressure to bidirectional piston simultaneously and provides pressure to moveable platen downwards, moveable platen promotes the downward jaw of upper gripper jaw and moves, meanwhile, the pitch brace of bidirectional piston pulls upper gripper jaw on lower jaw to move, by upper, lower jaw clamps workpiece.
The utility model has the advantage of: this hydraulically operated fixture carries out the adjustment of fixture by hydraulic pressure, what increase fixture steps up flexibility, by the needs stepped up workpiece, pressurize targetedly to first cylinder of the first hydraulic cylinder, in general hydraulic circuit, be provided with Pressure gauge, by the change of observed pressure table, control the clamping force to drive end bearing bracket, carry out power transmission by hydraulic pressure between jaw, reduce the mechanical loss to fixture itself in transmission process, improve the durability of fixture.
As preferred scheme, in order to prevent the pressure direction of former dynamic piston from offseting, described former dynamic piston centre is fixedly installed guide post, and bidirectional piston inside is provided with the inner chamber for guide post activity, guide post is constrained in vertical direction motion by inner chamber, and former dynamic piston can not be offset.
Preferably, described upper and lower jaw is provided with the fixture block with absorption surface, and this fixture block is connected on jaw by dormant bolt, because jaw often needs and absorption surface, easily cause the wearing and tearing of fixture block, change fixture block by demounting bolt, thus realize the durability of jaw.
Preferably, for the ease of changing and the control of pressure, described second hydraulic cylinder is connected with overflow control valve, by the adjustment of overflow control valve to maximum pressure.
Accompanying drawing explanation
Fig. 1: the structural representation of lathe hydraulic fixture in the present embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Lathe hydraulic fixture as shown in Figure 1, comprise hydraulic pressure end cap 1, bidirectional piston 7 and moveable platen 8, it is the U-shaped chamber of indent above described moveable platen 8, bidirectional piston 7 and indent U-shaped cavity wall are slidably matched, bidirectional piston 7 upper part indent, and edge is fixedly connected with hydraulic pressure end cap 1 and forms described first hydraulic cylinder, bidirectional piston 7 lower part and moveable platen 8 form described second hydraulic cylinder 4, former dynamic piston 2 is provided with in described first hydraulic cylinder, first hydraulic cylinder is divided into first cylinder 5 and second cylinder 6 by former dynamic piston 2, first cylinder 5 described is communicated with hydraulic power source, second cylinder 6 described is communicated with the second hydraulic cylinder 4, guide post 3 is fixedly connected with below former dynamic piston 2, the below of guide post 3 is cushioned by spring, offset below moveable platen 8 and be provided with upper gripper jaw 9, moveable platen 8 envisaged underneath has groove, upper gripper jaw 9 is produced to the stress extruded for reducing moveable platen, be pitch brace 13 below described bidirectional piston 7, described pitch brace 13 is fixedly connected with the lower jaw 12 mated with upper gripper jaw 9, on, lower jaw is provided with dismountable fixture block, described fixture block is connected with the body of jaw by bolt, fixture block can be changed upon wear, the place be slidably matched is needed to be provided with sealing ring at fixture, lathe hydraulic fixture when in use, petrolatum liquid is full of in advance in the second hydraulic cylinder 4, vaseline also can flow in second cylinder 6 of the first hydraulic cylinder by passage simultaneously, first cylinder 5 feed flow of the first hydraulic cylinder is given by hydraulic power source, now former dynamic piston 2 is movable to the second hydraulic cylinder 7 direction, because the hydraulic fluid pressure in second cylinder 6 of the first hydraulic cylinder increases, hydraulic oil is made to continue to flow in the second hydraulic cylinder 4, the hydraulic oil of the second hydraulic cylinder 4 provides pressure and provides pressure to moveable platen 8 downwards upwards to bidirectional piston 7 simultaneously, moveable platen 8 promotes upper gripper jaw 9 and moves in jaw 12 direction downwards, meanwhile, the pitch brace 13 of bidirectional piston 7 pulls lower jaw 12 to move to upper gripper jaw 9, by upper, the protecgulum 11 of lower jaw to gear pump clamps.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
