Abstract
The invention discloses a machine tool pressure plate, mainly comprising a screw rod hinged on a T-shaped draw bar, and a pressing plate and a cylinder body which are arranged on the screw rod. The machine tool pressure plate is suitable for clamping work-pieces with different heights by virtue of the characteristic that the T-shaped draw bar and the screw rod can rotate at hinge parts, and can fulfill the purpose of clamping the work-pieces in a manner that liquid plastic in the cylinder body expands to push a piston and generate large clamping force. The machine tool pressure plate has the advantages of being convenient to install and use as well as store and manage, being capable of generating large clamping force and ensuring reliability of clamping.
Description
Technical field
The present invention relates to a kind of lathe pressing plate, belong to Metal Cutting Machine Tool attachment technique field.
Background technology
At present, the employed pressing plate of Metal Cutting Machine Tool is the T connector bolt by general point, pressing plate and some the cushion blocks that highly do not wait form, in use, the T connector of T connector bolt partly assigns in the T-shaped groove of platen, pressing plate is arranged on T-shaped slot bolt bar position, the two ends of pressing plate respectively be installed in platen on workpiece and cushion block contact, screw thread position at T-shaped slot bolt is provided with nut, thereby will reach the purpose of workpiece pressing, form structure and working method can be found out by existing pressing plate, because the compression position height of workpiece is generally different, so, must change with the workpiece corresponding height cushion block, so, this just causes the quantity of cushion block more, is unfavorable for the keeping and management of workpiece, also exists simultaneously installation cumbersome, the defective that the reliability of workpiece pressing is relatively poor; In addition, this pressing plate is when workpiece pressing, and its thrust provides common nut, so, also there is the defective that thrust is less, be difficult for compressing larger workpiece.
Summary of the invention
The object of the invention is to: for the existing defects of existing lathe pressing plate, the invention provides a kind of novel lathe pressing plate, overcome the existing existing defects of lathe pressing plate.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of lathe pressing plate, it is by pressure strip, annular is lived and is matched, cylinder body, screw mandrel, the tensioner screw, liquid plastics, cushion block, bearing pin; T " type head pull bar forms, it is characterized in that: the bar section upper end of T connector pull bar is hinged actively with bearing pin with the lower end of screw mandrel, be provided with pressure strip at screw mandrel, cylinder body is installed on the screw mandrel on pressure strip top by screw thread in the middle of it, lower position at cylinder body is shaped with annular space, in annular space, be provided with annular piston, in the space of annular piston and cylinder body sealing, be filled with liquid plastics, be provided with the tensioner screw on the top of cylinder body, described tensioner screw bottom enters in the space of annular piston and cylinder body sealing, and described cushion block is an independently common block object.
The course of work of the present invention is: before work, the prime minister patches the T connector position of T connector pull bar in the T-shaped groove of platen, workpiece to be processed and cushion block are set respectively on the platen of T connector pull bar both sides, and the two ends that make pressure strip are overlapped on respectively above cushion block and the workpiece to be processed, at this moment, turn the cylinder body rotation, make cylinder part contact and produce in advance certain thrust with pressure strip, at this moment, turn the tensioner screw, liquid plastics is expanded, the liquid plastics pushing piston of expansion moves downward, thereby pressure strip is produced larger thrust, and with Work-sheet pressing.
Beneficial effect: can be found out by structural principle of the present invention and the course of work, the present invention compared with prior art, owing to just will arrive a cushion block, the needs that just can adapt to the differing heights Workpiece clamping, simultaneously, because the mode that clamping force mainly relies on the tensioner screw to make liquid plastics expansion and pushing piston move the larger thrust of generation is come clamping work pieces, so, that the present invention has advantages of is easy to install, clamping force is large, reliable clamping, and has advantages of convenient keeping and management.
Description of drawings
Accompanying drawing is structure principle chart of the present invention;
Shown in the figure: 1, pressure strip; 2, annular is lived and is matched; 3, cylinder body; 4, screw mandrel; 5, tensioner screw; 6, liquid plastics; 7, cushion block; 8, bearing pin; 9, T connector pull bar; 10, platen; 11, workpiece.
The specific embodiment
A kind of lathe pressing plate, comprise pressure strip 1, annular is lived and is matched 2, cylinder body 3, screw mandrel 4, tensioner screw 5, liquid plastics 6, cushion block 7, bearing pin 8, T connector pull bar 9, bar section upper end at T connector pull bar 9 is hinged actively with bearing pin 8 with the lower end of screw mandrel 4, be provided with pressure strip 1 at screw mandrel 4, cylinder body 3 is installed on the screw mandrel 4 on pressure strip 1 top by screw thread in the middle of it, lower position at cylinder body 3 is shaped with annular space, in the annular space of cylinder body 3 bottoms, be provided with annular piston 2, in the space that annular piston 2 and cylinder body 3 seal, be filled with liquid plastics 6, be provided with tensioner screw 5 on the top of cylinder body 3, tensioner screw 5 bottoms enter in the space of annular piston 2 and cylinder body 3 sealings, and cushion block 7 is independently common block objects.
Before work, the prime minister patches the T connector position of T connector pull bar 9 in the T-shaped groove of platen 10, workpiece to be processed 11 and cushion block 7 are set respectively on the platen 10 of T connector pull bar 9 both sides, and the two ends that make pressure strip 1 are overlapped on respectively cushion block 7 with above the workpiece 11 to be processed, at this moment, turn cylinder body 3 rotations, make cylinder body 3 parts contact and produce certain thrust with pressure strip 1 in advance, at this moment, turn tensioner screw 5, liquid plastics 6 is expanded, liquid plastics 6 pushing pistons 2 of expansion move downward, thereby pressure strip 1 is produced larger thrust, and workpiece 11 is compressed.
