Abstract
The invention discloses a universalized spiral scissors type jack for three-top parts and tools. The universalized spiral scissors type jack comprises a base and a jack head, wherein the base is integrally forged and formed by box iron; the jack head is forged and formed by a U-shaped piece; the base is hinged to a left lower support and a right lower support; forward teeth and reverse teeth which are meshed with each other are respectively arranged at the lower end of the left lower support and the lower end of the right lower support; a left upper support and a right upper support are hinged to the lower portion of the jack head; forward teeth and reverse teeth which are meshed with each other are respectively arranged at the upper end of the left upper support and the upper end of the right upper support; and the upper end of the left lower support and the lower end of the left upper support are respectively hinged to two ends of a nut. Two upper supports which serve as jack upper supports are hinged to the jack head, two jack lower supports which serve as jack lower supports are hinged to the base, so that the spiral double-scissors type jack is formed in a combined manner, and the universalization degree is high.
Description
Technical field
The present invention relates to jack field, specifically belong to three top parts and frock universalization spiral shearing jack.
Background technology
Scissor-like jack is bracket jack again, light and fast, be domestic each large automotive plant with car product, principle is had nothing in common with each other.The upper rack posts be made up of sheet metal and lower fulcrum bar form.The cross-sectional plane of upper rack posts and lower fulcrum bar teeth portion and near the cross-sectional plane of part be the rectangle of openings at one side, the metal sheet on opening both sides bends inwards.Tooth on upper rack posts and lower fulcrum bar is that the metal sheet that bent by opening both sides is made, and this kind of jack generalization degree is not high, uses inconvenience.
Summary of the invention
The object of this invention is to provide a kind of three top parts and frock universalization spiral shearing jacks, adopt two upper brackets as the hinged top of jack upper bracket, select two jack lower brackets as jack lower bracket articulated base, combine the two scissor-like jack of a spiral, generalization degree is high.
Technical scheme of the present invention is as follows:
Three top parts and frock universalization spiral shearing jacks, the base of channel-section steel one forging molding, the top of U-shaped part forging molding, base is hinged with a left side, right lower bracket, left, right lower bracket lower end is respectively equipped with just intermeshing, anti-tooth, top lower hinge has a left side, right upper bracket, left, right upper bracket upper end is respectively equipped with just intermeshing, anti-tooth, left lower bracket upper end and upper left pedestal lower end are articulated with the two ends of nut respectively, right lower bracket upper end and right upper bracket lower end are articulated with the two ends of pivot shaft respectively, described nut radial direction is provided with tapped through hole, pivot shaft radial direction is provided with pivot shaft through hole, screw mandrel is successively through surface bearing, pivot shaft through hole, fixed cover, screw through tapped through hole, jack is placed in minimum altitude.
The profile of tooth of described left and right lower bracket unanimously engages each other, carrier openings consistent size, hinged through hole and rotational axis hole consistent size, and the profile of tooth of left and right upper bracket is consistent, carrier openings is consistent, hinged through hole and rotational axis hole consistent size.
The positive and negative tooth of described left and right lower bracket is identical with the tooth profile parameter of the positive and negative tooth of left and right upper bracket, and rush tooth mould, whole tooth mould, piercing die are general.
The pin shaft hole of described left lower bracket, upper left support with rotational axis hole apart from equal, the pin shaft hole of right lower bracket, right upper bracket with rotational axis hole apart from equal.
The present invention adopts two upper brackets as the hinged top of jack upper bracket, selects two jack lower brackets as jack lower bracket articulated base, and combine the two scissor-like jack of a spiral, generalization degree is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the positive and negative tooth mesh schematic representation of support of the present invention.
Detailed description of the invention
See accompanying drawing, three top parts and frock universalization spiral shearing jacks, the base 1 of channel-section steel one forging molding, the top 2 of U-shaped part forging molding, base 1 is hinged with a left side, right lower bracket 3, 4, left, right lower bracket 3, 4 lower ends are respectively equipped with just intermeshing, anti-tooth 5, 6, come directly towards 2 lower hinge and have a left side, right upper bracket 7, 8, left, right upper bracket 7, 8 upper ends are respectively equipped with just intermeshing, anti-tooth 9, 10, left lower bracket 3 upper end and upper left support 7 lower end are articulated with the two ends of nut 11 respectively, right lower bracket 4 upper end and right upper bracket 8 lower end are articulated with the two ends of pivot shaft 12 respectively, nut radial direction is provided with tapped through hole, pivot shaft radial direction is provided with pivot shaft through hole, screw mandrel 13 is successively through surface bearing, pivot shaft through hole, fixed cover, screw through tapped through hole, jack is placed in minimum altitude.
The profile of tooth of left and right lower bracket unanimously engages each other, carrier openings consistent size, hinged through hole and rotational axis hole consistent size, and the profile of tooth of left and right upper bracket is consistent, carrier openings is consistent, hinged through hole and rotational axis hole consistent size.The positive and negative tooth of left and right lower bracket is identical with the tooth profile parameter of the positive and negative tooth of left and right upper bracket, and rush tooth mould, whole tooth mould, piercing die are general.The pin shaft hole of left lower bracket, upper left support with rotational axis hole apart from equal, the pin shaft hole of right lower bracket, right upper bracket with rotational axis hole apart from equal.
Rated load: 1000Kg
Maximum lift height 420 ± 2mm
Minimum fold height 105 ± 2mm
Maximum overall length 467 ± 5mm.
