The advantages are that: rational in infrastructure, convenient to use, location ring gear can mesh with the bidentate stick simultaneously, and is fixed with bidentate stick relative position, will disappear the keyway that the clearance key inserted the serrated stick again, and the driving chain clearance is eliminated to the location serrated stick, has improved work efficiency.
Description
Technical Field
The utility model relates to a frock for assembly of numerical control boring revolving stage.
Background
The transmission mechanism of the numerical control boring turntable mostly adopts single motor double-tooth bar transmission to eliminate gaps, when the equipment has gaps, a positioning key needs to be reconfigured and grinding is carried out, and the tooth bars need to be repeatedly taken out, ground and debugged. The side length of the table top of the numerical control boring turntable is at least 2 meters, the relative position between the double tooth rods must be a fixed position, otherwise the turntable cannot be installed in place, namely, the turntable can be effectively ground by blind adjustment for dozens of times on the premise that the actual condition of internal assembly cannot be seen by a worker, so that time is consumed, and the precision cannot be guaranteed.
Disclosure of Invention
For overcoming the not enough of prior art, the utility model aims at providing a frock for assembly of numerical control boring revolving stage conveniently eliminates the excellent transmission clearance of double rack of numerical control boring revolving stage, improves work efficiency.
In order to achieve the above object, the utility model discloses a following technical scheme realizes:
a tool for assembling a numerical control boring turntable comprises a positioning gear ring and an anti-backlash key, wherein the positioning gear ring is of a fan-shaped sheet structure, the outer arc of the fan-shaped sheet structure is provided with teeth, and the outer arc of the fan-shaped sheet structure is meshed with a double-tooth rod; the anti-backlash key can be inserted into a key groove of the gear rod, the anti-backlash key is a cuboid, and inclined stepped structures are arranged on two sides of the anti-backlash key.
The inclined angles of the steps at the two sides of the anti-backlash key are the same.
The anti-backlash key is divided into two parts.
Compared with the prior art, the beneficial effects of the utility model are that:
a frock for assembly of numerical control boring revolving stage is rational in infrastructure, and convenient to use, location ring gear can mesh with the bidentate stick simultaneously, and is fixed with the bidentate stick relative position, inserts the keyway of bar gear with the gap elimination key again, and the drive chain clearance is eliminated to the location bar gear, has improved work efficiency. The positioning gear ring adopts a fan-shaped structure, so that the positioning is convenient, and the weight is reduced.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.
Referring to fig. 1-5, the tool for assembling the numerical control boring turntable comprises a positioning gear ring 1 and an anti-backlash key 2, wherein the positioning gear ring 1 is of a fan-shaped sheet structure, the outer arc of the fan-shaped sheet structure is provided with teeth 4, and the outer arc of the fan-shaped sheet structure is meshed with a double-tooth rod 6; the anti-backlash key 2 can be inserted into a key groove 5 of the gear rod, the anti-backlash key 2 is a cuboid, and two sides of the anti-backlash key are provided with inclined step structures 3. Wherein, the ladder inclination angles of the two sides of the anti-backlash key 2 are the same. The anti-backlash key 2 comprises two parts and can simultaneously position the double-tooth rod 6.
After the double-tooth bar 6 is fixed through the positioning gear ring 1, the stepped structure 3 of the anti-backlash key 2 is connected with the key groove 5, the other side of the anti-backlash key 2 is connected with the inner side bevel gear shaft, and the more the anti-backlash key slides downwards, the smaller the corresponding mechanical clearance at the motor end is until the proper clearance is reached. The positioning of the ring gear 1 with the double toothed bar 6 must always remain in a fixed position during this process. After the positioning gear ring 1 is removed, the turntable is placed into the turntable for continuous use.
The positioning gear ring 1 can accurately position the double-tooth bar 6 and provides a basis for assembling a numerical control boring turntable. The anti-backlash key 2 is used for eliminating the transmission chain clearance and ensuring that the equipment meets the requirement of a servo drive system to reach the running precision.
When the device is used, the position of the positioning gear ring 1 is determined by scribing, the positioning gear ring 1 is installed according to the scribing position, an operator pulls out two positioning tooth bars, the anti-backlash key 2 is assembled, and the positioning gear ring 1 is used for ensuring the positions of the double tooth bars 6. After repeated grinding, an ideal transmission gap is achieved, and then the combined assembly is carried out, so that the device can be installed in place at one time.
