Detailed description of the invention
Describe the technical solution of the utility model in detail by the following examples, following embodiment is only exemplary, only can be used for explaining and the technical solution of the utility model being described, and can not be interpreted as being the restriction to technical solutions of the utility model.
As shown in Figure 1, dynamometer positioner forms primarily of two parts, and namely strut 2 and base 1 form, and during use, dynamometer is placed into the upper surface of base 1.
As shown in Figures 2 and 3, strut includes strut body 21, and strut body 21 is slab structure, and one end of strut body 21 is vertically bent to form kink 23, and kink 23 is provided with V-type opening 24; The pull bar (hook) of dynamometer stretches out from the U-shaped opening 104 base 1, vehicle body or other permanent plants withstand in V-type opening 24 place of kink 23, the part needing to apply pulling force to be connected with dynamometer pull bar (hook) by the V-type opening 24 of kink or pull bar passes V-type opening 24 and is connected with part, pull dynamometer base and dynamometer, pulling force can be applied to part.
Dynamometer pull bar (hook) and need to apply the parts of pulling force can by this V-type opening 24, vehicle body or permanent plant can be withstood when dynamometry in this position simultaneously; Strut 2 afterbody has the chamfering of certain angle, is convenient to base 1 and its assembling; Strut 2 upper surface has a ratchet bar 22, under itself and the acting in conjunction of base 1 positioned internal card 1071, base 1 can be made rearwardly to move, and to head movement, can not be mainly used in positioning base and prevent base from returning because of the effect of dynamometer spring force.
As shown in Figures 4 to 7, base 2 includes upper bed-plate 101 and lower bottom base 102; The upper surface of upper bed-plate 101 is for placing dynamometer, and the lower surface of upper bed-plate 101 is provided with convex groove 106, and the upper surface of lower bottom base 102 is provided with groove 1021; Convex groove 106 and groove 1021 are combined into convex endoporus; Strut body 21 penetrates described convex endoporus, ensure that and the coordinating of strut 2.Why whole base is made up of upper bed-plate 101 and lower bottom base 102 two parts, mainly considers the assembling of the location control mechanism 107 of chassis interior.
As shown in Figure 5, be provided with protuberance 103 upwards in one end of upper bed-plate 101, protuberance 103 be provided with U-shaped opening 104; At the first side wall of upper bed-plate 101, one end of protuberance is provided with installing hole, installing hole is communicated with convex groove; Location control mechanism 107 is also provided with near protuberance one end at convex groove 106; Location control mechanism 107 and the ratchet snap-fit engagement on ratchet bar 22.The lower surface both sides of described upper bed-plate 101 are respectively provided with at least two and install groove 105, and in the present embodiment, the lower surface both sides of upper bed-plate 101 are respectively provided with two and install groove 105, are altogether four and install groove, to assemble with the boss of lower bottom base; It is inner that location control mechanism 107 is positioned at upper bed-plate 101.
Lower bottom base 102 structure as shown in Figure 7, its inside dimension and strut measure-alike, be convenient to and the coordinating of strut 2, it has four boss 1022, installs groove 105 and coordinates, connected by Up/down base in aggregates by screw with four of upper bed-plate 101.
As shown in Figure 8 and Figure 9, described location control mechanism 107 includes return knob 1074, return bar 1072, positioning cards 1071 and return torsion spring 1073; Described return knob 1074 is structure as a whole with described return bar 1072; Described return bar 1072 penetrates described installing hole, and return torsion spring 1073 and positioning cards 1071 are installed on described return bar 1072 successively; Return knob 1074 and return bar 1072 are an entirety, and return knob 1074 is positioned on the right side of upper bed-plate, meet right-hand operated custom.
The surface that second sidewall of described upper bed-plate 101 is relative with described installing hole is provided with return bar fixing hole; The end of described return bar is stretched in described return bar fixing hole, can play like this and support the end of return bar, improves the stability of location control mechanism.
Part through described positioning cards 1071 on described return bar 1072 is non-circular structure; Described positioning cards 1071 penetrates the through hole 1075 of described return bar 1072 for non-circular; The area of described through hole 1075 is greater than the cross-sectional area of described return bar through the part of described positioning cards.In the present embodiment, part through described positioning cards on return bar is waist type structure, the through hole that positioning cards penetrates described return bar is waist type structure, main purpose prevents relatively rotating of positioning cards and return bar, can ensure that positioning cards is followed return bar and rotated when rotating return knob.
Wherein positioning cards is matched in clearance with coordinating of return bar, as shown in Figure 9, when mainly considering that dynamometer stretches, locator card sector-meeting because with the change of ratchet contact position and fluctuating up and down, drive the rotation fluctuation of return knob, after adopting matched in clearance, the gap of positioning cards and return bar makes the minor fluctuations of positioning cards can not cause the rotation of return bar and return knob, also can not produce larger idle stroke because of little gap on the contrary when rotating return knob.
Described return one end is butted on the bottom surface of described convex groove, and the other end is butted in described positioning cards; Under the effect of torsion spring, positioning cards remains and to contact with ratchet bar, blocks base, base can only be moved along a direction (dynamometer draw direction), and all can not return because of the effect of dynamometer spring force when moving to optional position.When rotating return knob, positioning cards is rotated along with return bar, and just can cancel the contact with ratchet bar, now base just can bidirectional-movement, to unclamp dynamometer, makes dynamometer return.
Can ensure accuracy when using dynamometer and convenience by the utility model, improve the efficiency in vehicle trial-manufacturing process, simple and practical, adaptability is comparatively strong, goes for all kinds of drawing dynamometer.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalency thereof.
