Description
Technical Field
The utility model relates to a mechanical fixture technical field, in particular to automatic aligning chuck of lever.
Background
At present, clamping used for product detection in the whole mechanical industry mostly adopts a diaphragm type, an elastic chuck, a hydraulic chuck, a pneumatic chuck and the like. Some clamping devices have large volume and poor clamping precision, have long clamping time in the production process, and can be used only by being matched with auxiliary equipment. The clamping and the concentricity are difficult to ensure, and the use is very inconvenient.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art existence, the utility model discloses a main aim at provides one kind and ensures concentric automatic aligning chuck of product internal diameter and rotation axis.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an automatic aligning chuck of lever, includes the base, the base center is provided with the fixed pipe of cavity, be provided with drive gear on the fixed pipe of cavity, be provided with 4 supporting parts around the equidistant base center on the base, form between two adjacent supporting parts and stretch out the groove, the meshing is connected with 4 jack catchs on the drive gear, the jack catch includes rack portion that can mesh with drive gear and the butt piece of being connected with rack portion, the butt piece sets up in stretching out the groove, drive gear can drive 4 rack portion simultaneously when rotating and rotate, still be provided with the limiting plate that can cover drive gear and jack catch on 4 supporting parts, be provided with in the fixed pipe of cavity can with drive gear fixed connection's drive shaft.
Preferably, the height of the support part is greater than that of the jaw.
Preferably, the abutting block is provided with a limiting block which can abut against the inner wall of the supporting part.
The utility model discloses have following advantage for prior art, because there is tolerance about the product internal diameter among the prior art, can have various clamping time errors when the chuck is installed to the product, lead to the product not on the concentric shaft, can automatic adjustment product and rotation axis concentricity after the chuck of this scheme is adorned. The chuck of this scheme mainly relies on gear lever principle, and 4 jack catchs open simultaneously during the clamping, ensure that product internal diameter and rotation axis are concentric, and its drive is realized through the drive shaft that sets up in the fixed pipe of cavity, and the drive shaft is not drawn in the drawing, has seted up the shape groove on the fixed pipe of cavity, is provided with the lug on the drive shaft and passes shape groove and drive gear fixed connection. Wherein when drive gear is rotatory, 4 jack catchs and stretches out or stretch into the groove of stretching out simultaneously, and 4 jack catchs stretch into inside the product and carry out the centre gripping. The chuck clamping of this scheme is convenient, fix a position accurate and small. The device is suitable for being used on an automatic production line which requires product clamping for accurate centering without resistance rotation, and the repeated clamping concentricity is within 0.005-0.01.
Drawings
Fig. 1 is a schematic view of the overall structure of a lever type automatic aligning clamp of the present invention;
fig. 2 is an exploded view of the lever type automatic aligning clamp of the present invention.
In the figure: 1. a base; 2. a hollow fixed tube; 3. a drive gear; 4. a support portion; 5. extending out of the groove; 6. a claw; 7. a rack portion; 8. a butting block; 9. a limiting plate; 10. and a limiting block.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, a lever type automatic aligning chuck comprises a base 1, a hollow fixing tube 2 is arranged in the center of the base 1, the hollow fixed tube 2 is provided with a driving gear 3, the base 1 is provided with 4 supporting parts 4 at equal intervals around the center of the base 1, a protrusion groove 5 is formed between two adjacent supporting parts 4, the driving gear 3 is engaged with 4 claws 6, the claws 6 comprise rack parts 7 capable of being engaged with the driving gear 3 and abutting blocks 8 connected with the rack parts 7, the abutting block 8 is arranged in the extending groove 5, the driving gear 3 can simultaneously drive the toothed bar part 7 to rotate when rotating, still be provided with the limiting plate 9 that can cover drive gear 3 and jack catch 6 on 4 supporting parts 4, be provided with in the fixed pipe 2 of cavity and can with drive gear 3 fixed connection's drive shaft.
This scheme's automatic aligning chuck of lever for among the prior art because there is tolerance about the product internal diameter, can have various clamping time errors when the chuck is installed to the product, lead to the product not on the concentric shaft, can automatic adjustment product and rotation axis concentricity after the dress arrives the chuck of this scheme. The chuck of this scheme mainly relies on gear lever principle, and 4 jack catchs 6 open simultaneously during the clamping, ensure that product internal diameter and rotation axis are concentric, and its drive is realized through the drive shaft that sets up in the fixed pipe 2 of cavity, and the drive shaft is not drawn in the drawing, has seted up the groove on the fixed pipe 2 of cavity, is provided with the lug on the drive shaft and passes groove and drive gear 3 fixed connection. Wherein when drive gear 3 was rotatory, 4 jack catchs 6 stretch out simultaneously or stretch into and stretch out groove 5, and 4 jack catchs 6 stretch into inside the product and carry out the centre gripping. The chuck clamping of this scheme is convenient, fix a position accurate and small. The device is suitable for being used on an automatic production line which requires product clamping for accurate centering without resistance rotation, and the repeated clamping concentricity is within 0.005-0.01.
Preferably, the height of the support 4 is greater than the height of the jaws 6. The advantage of this arrangement is that the jaws 6 are relatively smooth when extended or retracted.
Preferably, the abutting block 8 is provided with a limit block 10 which can abut against the inner wall of the supporting portion 4. This arrangement prevents the claw 6 from coming off the base 1.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
