Multi-shaft synchronous tightening equipment for wheel bolts

Abstract

The invention discloses multi-shaft synchronous tightening equipment for wheel bolts. The multi-shaft synchronous tightening equipment for the wheel bolts comprises a speed reducing mechanism, a reciprocating rotating mechanism and a tightening mechanism, wherein the input end of the speed reducing mechanism is connected with a motor or a shaking handle; the reciprocating rotating mechanism is connected with the output end of the speed reducing mechanism; and the tightening mechanism is connected with the output end of the reciprocating rotating mechanism. The multi-shaft synchronous tightening equipment is characterized in that the tightening mechanism comprises a chute disc, a peripheral adjusting sliding block, a detachable disc, a top cover, a tightening connecting rod, a tightening crank, a ratchet mechanism and bolt sleeves, wherein the peripheral adjusting sliding block is arranged on the chute disc; a hinged shaft is arranged on the surface of the detachable disc; the top cover covers the chute disc; one end of the tightening connecting rod is sleeved on the hinged shaft; the tightening crank is hinged to the tightening connecting rod; the ratchet mechanism is arranged on the upper surface of the tail end of the tightening crank; the bolt sleeves are arranged on the ratchet mechanism; the chute disc is sleeved on the periphery of the detachable disc; the radial adjusting sliding block and the tightening connecting rod are hinged to each other at a position corresponding to the circle center of the bolt sleeves; a plurality of rectangular holes which are uniformly distributed in the peripheral direction and correspond to radial chutes are formed in the surface of the top cover; and the sleeves arranged on the ratchet mechanism extend out from the rectangular holes.

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...

[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
