Summary of the invention
the object of this invention is to provide a kind of stretching and push against device, it has two-stage and stretches, and adds the scope of application.
for solving the problems of the technologies described above, the present invention adopts following technical scheme:
a kind of stretching pushes against device, comprise base plate, rotate the screw mandrel be arranged on described base plate, the nut assembly coordinated with described screw rod transmission, described nut assembly is fixed on the side of one piece of installing plate, the urceolus of a cylinder is fixedly mounted on the opposite side of described installing plate, described base plate is provided with a pair guide pillar, guide pillar described in a pair is mounted slidably a leading truck, the outer end of the piston rod of described cylinder is fixed on described leading truck, described leading truck is provided with can with the flexible of described piston rod the head that pushes against for pushing against workpiece of movement, the direction of axis line of described screw mandrel, the bearing of trend of described guide pillar is identical with the telescopic direction of described piston rod.
preferably, described nut assembly comprises and is threaded onto the nut on described screw mandrel and two clamping plate for the nut described in clamping position, and the Boards wall described in two is on described installing plate.
preferably, described lead is fixed on described base plate by the mount pad at two ends.
preferably, described push against head comprise be arranged on the support on described leading truck by securing member, the flexibility be arranged on described support pushes against sheet.
it is preferably, described that what push against sheet is a cambered surface for pushing against the face that pushes against of workpiece.
it is preferably, described that what push against sheet is two coaxial cambered surfaces for pushing against the face that pushes against of workpiece.
preferably, described leading truck is U-shaped, and it is enclosed within the guide pillar described in a pair respectively slidably with both sides.
preferably, described installing plate parallels with described base plate.
beneficial effect of the present invention is: adopt feed screw nut and cylinder two-stage can realize the mechanism of stretching, expand the scalable scope pushing against head, the size range of the workpiece that can apply is wider, the telescoping mechanism of two-stage: one-level adopts feed screw nut, another level adopts cylinder, and deficiency of cancelling out each other, makes structure more stable, save and wait for clamping time, easy and simple to handle, the face that pushes against pushing against head can be the various different forms matched with workpiece wall, and practicality is wider.
