Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a bolt anti-deviation device. Background Art

[0002] Bolts are a type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. Currently, when tightening a bolt, if the position of the bolt is offset, it is easy to cause the bolt to get stuck.

[0003] Patent document CN 213165183 U discloses a bolt anti-deviating device, including a support frame, an adjusting mechanism fixedly connected to the inner wall of the support frame, a limiting mechanism fixedly connected to the left side of the adjusting mechanism, sliding holes opened on both the front and rear sides of the support frame, the inner wall of the sliding hole is slidably connected to the surface of the limiting mechanism, a first limiting block fixedly connected to the left side of the inner wall of the support frame, a first arc groove opened on the right side of the first limiting block, and a locking mechanism fixedly connected to the upper surface of the limiting mechanism. This device is relatively cumbersome to use, and the device itself is not fixed, and it is still easy to be misaligned, which causes the position of the bolt to be offset, affecting the installation of the bolt. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a bolt anti-deviation device, which can effectively limit the bolt and prevent the bolt from deviating and getting stuck.

[0005] To this end, the technical solution of the utility model is: a bolt anti-deviation device, including a base, a mounting slot is provided in the middle of the base, and a bolt limit block is provided in the mounting slot; a plurality of suction cups are provided under the base, and the middle of the suction cups is connected with the internal air duct of the base; a vacuum assembly is provided above the base, and the vacuum assembly includes a vacuum cylinder, a piston rod and a support block, the vacuum cylinder is fixed on the base, a piston is provided at the bottom of the piston rod, the piston is placed in the vacuum cylinder, and an extended top plate is provided on the top of the piston rod, which is placed above the vacuum cylinder; a rotatable support block is provided on the side of the vacuum cylinder, and the support block can be inserted under the top plate.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the lower part of the vacuum cylinder is connected with the airway inside the base, and the upward movement of the piston rod can suck the air in the suction cup, and the suction cup is in a negative pressure state.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: an extended mounting plate is provided on the side of the vacuum cylinder, and the support block is rotatably mounted on the mounting plate via a rotating shaft.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the bolt limiting block is inserted into the installation slot, and a hexagonal limiting hole is provided in the middle of the bolt limiting block.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the internal airway of the base includes an annular main airway and multiple branch airways, one end of the branch airway is connected to the inside of the suction cup, and the other end is connected to the annular main airway; the annular main airway is connected to the inside of the vacuum cylinder through an exhaust airway.

[0010] When in use, select a suitable bolt limit block according to the specifications of the bolt, so that the bolt head is fixed by the limit hole of the bolt limit block; put the bolt into the hole to be screwed, press the base on the bolt installation surface, so that the bolt head is inserted into the limit hole, and the suction cup is tightly fitted with the bolt installation surface. The suction cup will discharge some air during the fitting process, and in order to increase the adsorption force of the suction cup, pull out the piston rod, and the piston rod drives the piston to move upward, thereby sucking more air inside the suction cup, and then turn the support block to the bottom of the piston rod top plate, which can prevent the piston rod from moving downward due to the action of air pressure, so that the base maintains a high suction state, ensuring that the bolt will not deviate during the installation process, thereby ensuring the installation quality of the bolt.

[0011] After the bolts are installed, turn the support block out from under the piston rod top plate to move the piston downward, and inject some gas into the suction cup again to reduce the suction force of the suction cup, making it easier to pull out the base and continue to install the next bolt.

[0012] Compared with the prior art, the beneficial effects of the utility model are: a pluggable bolt limit block is arranged on the base, which can limit bolts of different specifications; a suction cup is arranged under the base, and an exhaust assembly is also arranged, which can manually suck out part of the air in the suction cup to increase the suction force of the suction cup, so that the base can be adsorbed on the bolt installation surface, avoiding the bolt from being offset due to the displacement of the base, and ensuring the smooth assembly of the bolt.
