Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific examples, and the examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement between the various components in a certain posture. Situations, etc., if the specific posture changes, the directional indication also changes accordingly.

[0026] In addition, in the present invention, descriptions such as "first", "second" and so on are used for description purposes only, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly incl...

Abstract

The invention belongs to the technical field of automobile mechanical equipment, and particularly relates to a tire bolt demounting and tightening device. The tire bolt demounting and tightening device comprises four or more wrenches. The wrenches are driven by an input shaft via a power transmission system to rotate. The power transmission system is arranged on a fixed plate. Sliding grooves areformed in the fixed plate, cooperating barrel-shaped sliding blocks are arranged in the sliding grooves, and limiting clamp sheets are formed at the middle positions of the sliding blocks. A center gear ring is arranged on the outer portion of the input shaft in a sleeving manner and is engaged with planet gear rings, and the planet gear rings are arranged on first universal rods in a sleeving manner. The first universal rods are connected with second universal rods, the second universal rods are connected with third universal rods, the third universal rods penetrate through the sliding blocksand cooperate with the inner walls of the sliding blocks, and the third universal rods are sleeved with the wrenches. A telescopic rod is arranged at the circle center position of the fixed plate, the tail end of the telescopic rod is connected with the input shaft through clutches, and the two ends of push rods are hinged to the telescopic rod and the sliding blocks. The defects that at present,the work efficiency of demounting tires and fixing bolts by manpower is low, and the degrees of tightening force of manually tightening the tires and fixing the bolts are different are remedied.

Description

technical field [0001] The invention belongs to the technical field of vehicle mechanical equipment, and in particular relates to a tire bolt dismounting and tightening device. Background technique [0002] At present, tire disassembly and tightening in the automobile maintenance industry is mainly completed by manpower, which has low work efficiency, high labor intensity, and no guarantee of operation safety. Therefore, an automatic tire disassembly machine is needed. Due to the different diameters of existing tires, the distance between the bolts used to fix the tire is also different. In order to make the tire automatic disassembly system automatically adjust the distance between the wrenches to deal with the disassembly of different types of tires, it is necessary to provide an adjustable wrench. distance between tire removal and tightening devices. During the tire tightening process, if it is done manually, there may be different pre-tightening forces between different...
