Problems solved by technology

[0002] At present, the assembly of the tire bolts of our military equipment vehicles under field conditions mainly relies on the use of a simple wrench. This traditional manual tightening method has many disadvantages: only one bolt can be tightened at a time, which is inefficient; the torque during the tightening process cannot be adjusted. , The tightening sequence is precisely controlled, the randomness is large, and the assembly accuracy is low
However, the single-axis tightening machine, like the traditional manual tightening method, can only tighten one bolt at a time, and cannot control the stress interaction between the bolts during the tightening process, so it is not suitable for vehicle tire repair and assembly under field conditions.
Multi-axis tightening machines are often used to assemble automobile tires because they can tighten multiple bolts at the same time, but multi-axis tightening machines are expensive and have fixed tightening heads, so they can only repair and assemble one type of vehicle tires; There are various types of vehicles, and the tires are also of different sizes. If the troops are equipped with a variety of multi-axis tightening machines, the maintenance cost will inevitably be too high
Some multi-axis tightening mechanisms can realize the adjustment of the tightening head, but due to the disadvantages of complex structure, troublesome operation, and high cost, they cannot be widely used in the maintenance and assembly of vehicle tires

Abstract

The invention discloses a multi-axis synchronous tightening device for wheel bolts, comprising a deceleration mechanism whose input end is connected to a motor or a shaking handle, a reciprocating mechanism connected to the output end of the deceleration mechanism, and a tightening mechanism connected to the output end of the reciprocating mechanism; its features That is, the tightening mechanism includes a chute disc, a circumferential adjustment slider mounted on the chute disc, a detachable disc with a hinge shaft on the surface, a top cover covering the chute disc, and a sleeve at one end. The tightening connecting rod on the hinge shaft, the tightening crank hinged with the tightening connecting rod, the ratchet mechanism arranged on the upper surface of the tightening crank end, the bolt sleeve assembled on the ratchet mechanism, the chute disc is covered on the detachable circular On the periphery of the disk, the radial adjustment slider and the tightening connecting rod are hinged at the position corresponding to the center of the bolt sleeve on the tightening connecting rod; the surface of the top cover is provided with a plurality of evenly distributed circumferentially corresponding to the radial chute. A rectangular hole through which the sleeve fitted on the ratchet mechanism protrudes.

Description

technical field [0001] The invention relates to vehicle maintenance equipment, in particular to a multi-axis synchronous tightening equipment for wheel bolts. Background technique [0002] At present, the assembly of the tire bolts of our military equipment vehicles under field conditions mainly relies on the use of a simple wrench. This traditional manual tightening method has many disadvantages: only one bolt can be tightened at a time, which is inefficient; the torque during the tightening process cannot be adjusted. , The tightening sequence is precisely controlled, with large randomness and low assembly accuracy. For this reason, it is necessary to introduce a bolt tightening device capable of simultaneously accurately and efficiently assembling tire bolts of equipped vehicles. [0003] Electric wrenches and pneumatic wrenches are often used for maintenance and assembly because they can control the torque and realize automatic tightening. However, the single-axis tigh...
