Description
Technical field
The present invention relates to a kind of bent axle bracing or strutting arrangement, specifically a kind of bent axle centre of support frame support force self-checking device.
Background technology
We know that bent axle, camshaft etc. is a kind of special-shaped slender axles, and intensity is low relatively, cause the cutter that shakes easily like no centre frame support during turning, and roughness does not reach technological requirement, and the general rule cylinder axis can use follow-rest.Therefore, during bent axle turning, must there be centre frame to support.And traditional centre frame adopts hard the support, and rigidity is very strong, and complex structure, and during adjustment centre frame support force, difficulty or ease are grasped the size of power, and it is overproof very easily to cause crankshaft journal to beat.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of rational in infrastructure, makes simply bent axle centre of support frame support force self-checking device easy to use.It is used for a non-rule axle type turning process support and uses with cutter.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of bent axle centre of support frame support force self-checking device; It comprises V-type back-up block, adjustable plate, connecting bolt, cylinder contiguous block; Two connecting bolt that laterally arranges one ends are connected fixing with adjustable plate; It is fixing that the other end is connected with the cylinder contiguous block, and it is characterized in that: said V-type back-up block rear portion is provided with groove, and adjustable plate is regulated in the removable groove that is installed in the V-type back-up block of bolt through two; Regulate in the groove on the bolt and be set with the dish spring, regulate bolt and pass the screwed hole that adjustable plate, dish spring and V-type back-up block be provided with and be fixedly connected.Be installed in the decrement of dish spring in the groove of V-type back-up block rear end through adjusting, automatically the size of adjustable support power.
Also be provided with guide post between V-type back-up block according to the invention, adjustable plate and the cylinder contiguous block; Guide post one end is threaded and is connected fixing through nut with the cylinder contiguous block; The other end passes adjustable plate and inserts in the pilot hole that the V-type back-up block is provided with, and on the guide post between V-type back-up block and the adjustable plate adjusting, is set with the dish spring.Like this, V-type back-up block relative adjustment plate moves forward and backward along guide post.The dish spring of suit plays the size of auxiliary adjustment support force on the guide post.
Also be axially arranged with guide protrusions on the V-type back-up block groove inwall of the present invention, correspondingly be provided with gathering sill on the said adjustable plate perimeter wall.Like this, adjustable plate has limited the rotation of V-type back-up block, and the V-type back-up block can only move forward and backward along guide post.
The present invention regulates in V-type back-up block rear end the dish spring is installed on bolt and the guide post, and during use, the V-type back-up block is resisted against on the crankshaft journal that turning cutting tool will process, and utilizes cylinder (or oil cylinder) strength, supports corresponding crankshaft journal through the V-type back-up block.Crankshaft journal rotation, the beating of crankshaft journal itself cause advancing of V-type back-up block or retreat, and the dish spring is realized the automatic adjusting that support force is big or small along with the V-type back-up block advances or retreat the decrement of automatic adjusting dish spring.Against existing technologies, the present invention is rational in infrastructure, makes simply, and easy to use, support force can be regulated automatically, is a kind of desirable bent axle centre of support frame support force self-checking device.It is used for a non-rule axle type turning process support and uses with cutter.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further description.
Fig. 1 is a structural representation of the present invention.
Label among the figure is: 1.V type back-up block, 2. dish spring, 3. adjustable plate, 4. connecting bolt, 5. guide post, 6. adjusting bolt, 7. cylinder contiguous block.
The specific embodiment
As can be seen from Figure 1; A kind of bent axle centre of support frame support force self-checking device; It is fixing that it comprises that V-type back-up block 1, adjustable plate 3, connecting bolt 4,7, two connecting bolt that laterally arranges 4 one ends of cylinder contiguous block are connected with adjustable plate 3, and the other end is connected fixing with cylinder contiguous block 7.Said V-type back-up block 1 rear portion is provided with groove, and adjustable plate 3 is regulated in the removable groove that is installed in V-type back-up block 1 of bolts 6 through two.Like this, V-type back-up block 1 is connected with cylinder contiguous block 7 with connecting bolt 4 through adjustable plate 3, cylinder contiguous block 7 again with the centre of support frame on cylinder be connected.
Regulate on the bolt 6 in said V-type back-up block 1 rear groove and be set with dish spring 2, adjusting bolt 6 passes adjustable plate 3, dish spring 2 is fixedly connected with the screwed hole that V-type back-up block 1 is provided with.Be installed in the decrement of dish spring in the groove of V-type back-up block rear end through adjusting, automatically the size of adjustable support power.In addition, the degree of depth that bolt gets into screwed hole is regulated in adjustment, can adjust the size of support force pretightning force.
Also be provided with guide post 5 between V-type back-up block according to the invention 1, adjustable plate 3 and the cylinder contiguous block 7; Guide post 5 one ends are threaded and are connected fixing through nut with cylinder contiguous block 7; The through hole that the other end passes adjustable plate 3 inserts in the pilot hole that V-type back-up block 1 is provided with, and on the guide post 5 between V-type back-up block 1 and adjustable plate 3 adjustings, is set with dish spring 2.Like this, V-type back-up block 1 relative adjustment plate 3 moves forward and backward along guide post 5.The dish spring 2 of suit plays the size of auxiliary adjustment support force on the guide post 5.
Also be axially arranged with guide protrusions on the V-type back-up block 1 groove inwall of the present invention, correspondingly be provided with gathering sill on said adjustable plate 3 perimeter walls.Like this, adjustable plate 3 has limited the rotation of V-type back-up block 1, and V-type back-up block 1 can only move forward and backward along guide post 5.
The present invention is installed in the V-type back-up block 1 rear end groove or adjusting bolt 6, adjustable plate 3, the guide post 5 at groove rear portion, protects because of V-type back-up block 1 is arranged, and the iron filings of having avoided producing in the process are to the adverse effect of centre of support frame.
The present invention is at V-type back-up block rear end guide post and regulate the dish spring is installed on the bolt, and during use, the V-type back-up block is resisted against on the crankshaft journal that turning cutting tool will process, and utilizes cylinder (or oil cylinder) strength, supports corresponding crankshaft journal through the V-type back-up block.Crankshaft journal rotation, the beating of crankshaft journal itself cause advancing of V-type back-up block or retreat, and the dish spring is along with the V-type back-up block advances or retreat the decrement of automatic adjusting dish spring; Realize the automatic adjusting of support force size; It is rational in infrastructure, makes simple, easy to use; Support force can be regulated automatically, is a kind of desirable bent axle centre of support frame support force self-checking device.It is used for a non-rule axle type turning process support and uses with cutter.
