Abstract
The utility model discloses a kind of blank compensation apparatus, including block, spring, adjustment bolt, adjusting seat, adjusting nut and gland, one end of one end connection adjustment bolt of the block, the other end of adjustment bolt sets gradually adjusting seat, adjusting nut, gland and spring from outside to inside, the adjusting seat, gland and spring are nested with adjustment bolt, and adjusting nut coordinates with adjustment bolt screw thread.The utility model is simple in construction, reasonable in design, can compensate the backlash of wheel and rack, reaches the purpose for improving transmission accuracy and repetitive positioning accuracy.
Description
Technical field
The utility model belongs to rack-and-pinion technical field, more particularly to a kind of blank compensation apparatus.
Background technology
At present in many mechanical structures, in order to realize mutual linear motion, much all matched somebody with somebody by wheel and rack
Close and realize.But backlash be present during wheel and rack cooperation, therefore reduce transmission accuracy and repetitive positioning accuracy.
Therefore, how to solve the defects of above-mentioned prior art is present becomes the direction that art personnel make great efforts.
Utility model content
The purpose of this utility model is just to provide a kind of blank compensation apparatus, can be fully solved above-mentioned the deficiencies in the prior art
Part.
The purpose of this utility model is realized by following technical proposals：
A kind of blank compensation apparatus, including block, spring, adjustment bolt, adjusting seat, adjusting nut and gland, the gear
One end of one end connection adjustment bolt of block, the other end of adjustment bolt set gradually adjusting seat, adjusting nut, pressure from outside to inside
Set and spring, the adjusting seat, gland and spring are nested with adjustment bolt, and adjusting nut coordinates with adjustment bolt screw thread.
Further, the adjustment bolt is mutually perpendicular to block.
Further, the adjusting nut has 2.
Compared with prior art, the beneficial effects of the utility model are：It is simple in construction, it is reasonable in design, tooth can be compensated
The backlash of wheel and rack, reach the purpose for improving transmission accuracy and repetitive positioning accuracy.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model；
Fig. 3 is the A-A cross-sectional views in Fig. 2.
Embodiment
The utility model is further described with reference to specific embodiments and the drawings.
As shown in Figure 1 to Figure 3, a kind of blank compensation apparatus, including block 1, spring 2, adjustment bolt 3, adjusting seat 4, tune
Whole nut 5 and gland 6, one end of one end connection adjustment bolt 3 of the block 1, the other end of adjustment bolt 3 from outside to inside according to
Secondary setting adjusting seat 4, adjusting nut 5, gland 6 and spring 2, the adjusting seat 4, gland 6 and spring 2 are nested with adjustment bolt 3
On, adjusting nut 5 coordinates with the screw thread of adjustment bolt 3.
The adjustment bolt 3 is mutually perpendicular to block 1.The adjusting nut 5 has 2, and one of them is used to adjust gland 6
The compression degree of spring 2 between block 1, another is used to contact with adjusting seat 4 so as to fixed adjustment bolt 3.
Referring to Fig. 2 and Fig. 3, when in use, this blank compensation apparatus is applied to the fortune coordinated by rack-and-pinion
On dynamic component.Motor 7 is arranged on installing plate 8 by bolt, and the installing plate 8 tightens screw 9 and one by three
Positioning screw 10 is fastened on slide plate 11.Tighten screw 9 for described three and be configured with fixed cover 12 respectively, the positioning screw 10 is matched somebody with somebody
Positioning sleeve 13 is cased with, needs to ensure that the installing plate 8 is active after fixed cover 12 and positioning sleeve 13 installation.It is sliding
Plate 11 is slidably fitted on a pedestal, and rack is installed on pedestal, the output end installation gear of motor 7, gear and tooth
Bar engages.One end of the block 1 is fastened on the installing plate 8 by soket head cap screw, other end connection adjustment bolt 3,
The adjusting seat 4 is fastened by bolts in the slide plate 11, during the wheel and rack engaged transmission, the installation
Plate 8 can be acted on around the axis minor rotation of the positioning sleeve 13, while by block 1 and the reciprocating compression of spring 2, can be compensated
The effect of the wheel and rack backlash, reaches the purpose being driven in high precision, also improves repetitive positioning accuracy.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
