Abstract
The utility model relates to a supporting arrangement for milling process, specifically a long travel floating support. The technical solution of the utility model is characterized in that a guiding base is provided on a frame, a mounting hole is provided on the guiding base, a cylinder is provided on the rear part of the guiding base, the piston rod of the cylinder is inserted in the mounting hole on the guiding base, a push pin with a stopper ring arranged thereon is connected on the front end of the piston rod, a push rod with a pressure head provided in the front end thereof is slidingly inserted in the mounting hole before the push pin, a spring is compressed between the installation blind hole on the rear end of the push rod and the stopper ring, and a guide bush for radial positioning of the push rod and a clamping bush which is elastically deformable in radial direction are provided on the external of the push rod and inside the guiding base. The floating support effectively prevents a workpiece from deformation when the load is void, and facilitates adjusting supporting force. A large gap is arranged between a workpiece and the floating support in operation, so that loading and unloading workpieces is much easier.
Description
Technical field
Supporting arrangement when the utility model relates to a kind of Milling Process, especially a kind of long-stroke floating support.
Background technology
When the big plane of machining large workpiece, in order to improve the rigidity of workpiece, reduce the milling vibration, guarantee crudy, often need to be provided with floating support, require designed unsteady support to satisfy simultaneously: 1, supporting force can not be too big, bigger distortion occurs to prevent workpiece profile under the state of virtual pressure.2, behind the push rod contact workpiece, should have bigger support force, make workpiece have enough rigidity man-hour, the stronger ability of resisting vibration adding.3, push rod should have bigger flexible stroke, is convenient to workpiece loading and unloading.Select existing over draft oil cylinder for use,, make that distance is too small between over draft oil cylinder and the workpiece though can satisfy above-mentioned the 1st, the 2nd requirement, sometimes can not workpiece loading and unloading.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of long-stroke floating support is provided, and this floating support can effectively be avoided the workpiece distortion that profile occurs under the virtual pressure state, makes things convenient for the adjusting of support force size; And the distance between when work and workpiece is bigger, therefore is convenient to workpiece loading and unloading.
The technical scheme that provides according to the utility model, on frame, fixedly install guide holder, offer installing hole in the guide holder, be provided with oil cylinder at the guide holder rear portion, the piston rod of oil cylinder is plugged in the installing hole of guide holder, front end at piston rod is connected with ejector pin, on ejector pin, be provided with baffle ring, sliding plug has push rod in the installing hole of ejector pin front end, the leading section of push rod is connected with pressure head, between the rearward end of push rod and baffle ring, be compressed with spring, but in the guide holder of push rod outside, be provided with the pilot bushing of push rod radial location and the clamp sleeve of radial elastic distortion.
Offer installing blind along its axis direction in the rearward end of push rod, the spring front end embeds in the installing blind, and the rear end of spring is socketed in outside the ejector pin, and the rear end of spring is against on the baffle ring.Leading section at guide holder is provided with the dust cap that is socketed in the push rod outer wall.Be provided with gasket ring in the installing hole of guide holder, described ejector pin inserts in the gasket ring and relies on the gasket ring inwall.
When the utility model uses, can avoid workpiece profile under the state of virtual pressure distortion to occur, the adjusting of support force size is also more convenient; And the distance between when work and workpiece is bigger, therefore is convenient to workpiece loading and unloading.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: on frame 1, fixedly install guide holder 2, offer installing hole 12 in the guide holder 2, be provided with oil cylinder 3 at guide holder 2 rear portions, the piston rod 4 of oil cylinder 3 is plugged in the installing hole 12 of guide holder 2, front end at piston rod 4 is connected with ejector pin 5, on ejector pin 5, be provided with baffle ring 6, sliding plug has push rod 7 in the installing hole 12 of ejector pin 5 front ends, the leading section of push rod 7 is connected with pressure head 8, between the rearward end of push rod 7 and baffle ring 6, be compressed with spring 9, but in the guide holder 2 of push rod 7 outsides, be provided with the pilot bushing 15 of push rod radial location and the clamp sleeve of radial elastic distortion.
Offer installing blind 11 along its axis direction in the rearward end of push rod 7, spring 9 front ends embed in the installing blind 11, and the rear end of spring 9 is socketed in outside the ejector pin 5, and the rear end of spring 9 is against on the baffle ring 6.Leading section at guide holder 2 is provided with the dust cap 13 that is socketed in push rod 7 outer walls.Be provided with gasket ring 14 in the installing hole 12 of guide holder 2, described ejector pin 5 inserts in the gasket ring 14 and relies on gasket ring 14 inwalls.
Operation principle of the present utility model is: start oil cylinder 3, make oil cylinder 3 promote piston rod 4, ejector pin 5, spring baffle ring 6, spring 9, push rod 7, pressure head 8 is to left movement, and rapid contact workpiece, under the pressure oil effect, continue to promote piston rod 4 to left movement, up to whole strokes of covering piston rod 4, piston rod 4 is through ejector pin 5, spring baffle ring 6 and then compression spring 9, at this moment, the supporting force of 8 pairs of workpiece of pressure head is decided by the stiffness coefficient of spring 9 and the product of deflection, irrelevant with the pressure size of oil cylinder 3 oil suction chambers, when the thrust of pressure head 8 reaches requirement, starting clamp sleeve 10 makes clamp sleeve 10 (power of holding tightly also claims support force to hold push rod 7 tightly along the radial contraction of push rod 7, relevant with the geometric parameter of oil cylinder working-pressure and oil pressure clamp sleeve), to improve the rigidity of work mounting s point.After the completion of processing, piston rod 4 moves to right, and pulling ejector pin 5, gasket ring 14, push rod 7, pressure head 8 move to right, and this moment, spring 9 decrements were replied, and pressure head 8 rollbacks distance should be oil cylinder 3 strokes and deducts spring 9 compression and back complexors.
