Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to operate, reliable operation, adjustable for height V-type back-up block.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of adjustable for height V-type back-up block, it is provided with base, V-block, two wedge slide blocks, leading screw, it is characterized in that: on described base, be arranged with two inclined-planes, V-block is positioned at top, two inclined-planes of base, and a centration axis is installed between described base and V-block up and down; Described two wedge slide block symmetries are arranged between two inclined-planes and V-block of base, in two wedge slide blocks, be provided with the tapped through hole that direction of rotation is contrary, described leading screw is arranged in the tapped through hole of two wedge slide blocks, rotational lead screw drives two wedge slide blocks whiles laterally or medial movement, support V-block and move downward or upward relative to base, realize V-block height adjustable.
A circulator is installed in described leading screw one end.Drive leading screw rotation by turning rotator.
Described centration axis upper end is fixed in the hole of V-block bottom surface, and centration axis bottom is through the centre bore of base, and bottom is fixed by nut, is also arranged with spring in the centration axis between base and nut.
The middle part of described centration axis is provided with a central through hole, and leading screw is through the central through hole of centration axis.
The present invention adopts above-mentioned composition structure, drives two wedge slider support V-blocks to move downward or upward relative to base by leading screw, realizes V-block height adjustable.Against existing technologies, the present invention is simple in structure, easy to operate, reliable operation, adjustable for height V-type back-up block.Be applicable to support various accurate axial workpieces, while measuring part, can adjust part to suitable height, make parts measurement more convenient.
Brief description of the drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is that the present invention forms structural representation.
1. bases in figure, 2. wedge slide block, 3. leading screw, 4.V type piece, 5. circulator, 6. spring, 7. centration axis, 8. nut.
Detailed description of the invention
As can be seen from Figure 1, a kind of adjustable for height V-type back-up block, it is provided with base 1, V-block 4, two wedge slide blocks 2, leading screw 3, also has a centration axis 7 and a circulator 5.Base and wedge slide block are made after by the modifier treatment of 42CrMo material, carry out surface hardening processing after machining, and ensure enough hardness and wearability.V-block and circulator are made after by 45 Steel material modifier treatment.Centration axis and leading screw are made after by the modifier treatment of 40Cr material, and modified rear hardness, between HRC50-55, ensures enough hardness and intensity.After machining, carry out surface gas nitrogen treatment, ensure enough wearabilities.
On described base 1, be arranged with two inclined-planes, V-block 4 is positioned at top, two inclined-planes of base, and centration axis 7 is installed between described base and V-block up and down; Described two wedge slide block 2 symmetries are arranged between two inclined-planes and V-block 4 of base 1, in two wedge slide blocks 2, be provided with the tapped through hole that direction of rotation is contrary, described leading screw 3 is arranged in the tapped through hole of two wedge slide blocks, and the hand of spiral at leading screw 3 two ends is contrary.Rotational lead screw 2 drives 2 whiles of two wedge slide blocks laterally or medial movement, supports V-block 4 and moves downward or upward relative to base 1, realizes V-block height adjustable.
Circulator 5 is installed in described leading screw 3 one end.Drive leading screw 3 to rotate by turning rotator 5.
Described centration axis 7 upper ends are fixed in the hole of V-block 4 bottom surfaces, and centration axis 7 bottoms are through the centre bore of base 1, and bottom is fixing by nut 8, in the centration axis 7 between base 1 and nut 8, is also arranged with spring 6.Ensure that V-block only moves up and down at above-below direction.
The middle part of described centration axis 7 is provided with a central through hole, and leading screw 3 is through the central through hole of centration axis.
When installation first, together with wedge slide block 2 is screwed in by screw thread with leading screw 3.Carve on two inclined-planes that type slide block 2 is placed in base 1 mounted.One end of centration axis 7 is fixed in the hole of V-block 4 bottom surfaces, with hole interference fit.The middle part of centration axis 7 is provided with a central through hole, and leading screw 3 is through the central through hole of centration axis 7.Centration axis 7 bottoms are through the centre bore of base 1, and fixing by spring 6 and nut 8, now the bottom surface of V-block 4 contacts completely with the upper surface of wedge slide block 2.Circulator 5 is arranged on leading screw 3 to interference fit between the external diameter of leading screw 3 and circulator 5.Like this, drive leading screw 3 to rotate by circulator 5, two wedge slide blocks 2 laterally or medial movement simultaneously, support V-block 4 and steadily move downward or upward relative to base 1, and V-block height declines or rising.
The present invention drives two wedge slider support V-blocks to move downward or upward relative to base by leading screw, realizes V-block height adjustable.It is simple in structure, easy to operate, reliable operation, adjustable for height V-type back-up block.Be applicable to support various accurate axial workpieces, in the time measuring part, can adjust part to suitable height, make parts measurement more convenient.
