Existing apparatus is a kind of cuniform increase power mechanism, relies on the support by mechanical axis, utilizes the feature of cuniform increase power, apply pressure by wedge shape part to workpiece.Its shortcoming is obvious: 1, function singleness.Device only can complete the compression to workpiece 2; 2, impact location.Wedge shape part and workpiece 2 contact surface are comparatively large, the large end of wedge shape part are being knocked in afterburner process to the slippage very easily causing workpiece 2 and workpiece 1 relative position, are changing the former position location of workpiece 2, bring uncertain factor to assembling; 3, not easily real-time inspection.After workpiece 2 positioning compression, because of the restriction by the larger profile of wedge shape part, inconvenience is checked in time to the relative position of the workpiece 2 after positioning compression and workpiece 1; 4, produce noise.The compression of workpiece 2 must knock wedge shape part end, produces larger knock thus, adds Production Regional noise, the occupational health of unfavorable operating personnel.
Utility model content
The utility model mainly solves the technical problem existing for prior art; Provide a kind of mechanism calmness, without impacting, not destroying by the pressure fixed position location of workpiece, ensure that a kind of V-type eccentric wheel positioning compression device of accurate positioning.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of V-type eccentric wheel positioning compression device, for by the manufacture of rolling stock, maintenance, assembling and positioning between two connectors of machine-building, two connectors are respectively the first workpiece and second workpiece, wherein, second workpiece upper surface is an isosceles triangle, needs second workpiece is compacted to the first Workpiece fixing and prevents compaction process to be shifted; It is characterized in that, comprise an eccentric wheel, described eccentric wheel is provided with the contact surface of second workpiece the V-shaped groove coordinated with it, and the isosceles triangle part of second workpiece is positioned at V-shaped groove placement compaction process eccentric wheel and second workpiece generation relative displacement causes second workpiece to be shifted; Described eccentric wheel circumference is inserted with a locating shaft; Described locating shaft two ends are positioned at the original chute of the first workpiece; Described eccentric wheel excircle radial direction has at least one and inserts for little crow bar and the rotary bar jack rotated with movable eccentric wheel.
At above-mentioned a kind of V-type eccentric wheel positioning compression device, described locating shaft one end is fixed with the spacing shelves of locating shaft, described locating shaft is also provided with axial location labeled slots between the spacing shelves of locating shaft and locating shaft center, and compaction process shows second workpiece accurate positioning when locating shaft inserts eccentric wheel and exposes axial location labeled slots.
At above-mentioned a kind of V-type eccentric wheel positioning compression device, described rotary bar jack is for being four, and even branch is on eccentric wheel excircle.
Therefore, the utility model tool has the following advantages: 1. reasonable in design, and structure is simply and completely practical; 2. mechanism calmness, nothing are impacted, and do not destroy by the pressure fixed position location of workpiece, ensure that accurate positioning, improve working environment; 3. utilize the isoceles triangle external surface of workpiece back projection to be locating surface, coordinated with it by V-arrangement eccentric wheel, the stressed s function of original device is expanded, increase telltale mark groove thereon, check whether eccentric wheel end face is in telltale mark groove, achieve the location of workpiece 2 assembling process and the position location checking function after compressing, location, compression, inspection are integrated, improve operating efficiency.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
First, introduce structure of the present utility model, the utility model is used for the manufacture of rolling stock, maintenance, assembling and positioning between two connectors of machine-building, two connectors are respectively the first workpiece 7 and second workpiece 6, wherein, second workpiece 6 upper surface is an isosceles triangle, needs second workpiece 6 to be compacted to the first workpiece 7 and locates and prevent compaction process to be shifted; Comprise an eccentric wheel 2, described eccentric wheel 2 is provided with the contact surface of second workpiece 6 V-shaped groove coordinated with it, and the isosceles triangle part of second workpiece 6 is positioned at V-shaped groove and places compaction process eccentric wheel 2 and with second workpiece 6, relative displacement occurs and cause second workpiece 6 to be shifted; Described eccentric wheel 2 circumference is inserted with a locating shaft 1; Described locating shaft 1 two ends are positioned at the original chute of the first workpiece 7; Described eccentric wheel 2 excircle radial direction has at least one and inserts for little crow bar and the rotary bar jack 3 rotated with movable eccentric wheel; Rotary bar jack 3 is four, and even branch is on eccentric wheel excircle.
Locating shaft 1 one end is fixed with the spacing shelves 5 of locating shaft, described locating shaft 1 is also provided with axial location labeled slots 4 between the spacing shelves 5 of locating shaft and locating shaft 1 center, and compaction process shows second workpiece 6 accurate positioning when locating shaft 1 inserts eccentric wheel 2 and exposes axial location labeled slots 4.
During use, locating shaft 1 determines position by the sidewall of the spacing shelves 5 of the locating shaft on it and the first workpiece 7, and second workpiece 6 determines position by V-arrangement eccentric wheel 2 according to the axial location labeled slots 4 on locating shaft 1.Once behind second workpiece 6 location, rotate V-arrangement eccentric wheel 2, thus the location realized second workpiece 6 and compression.Location groove width on locating shaft 1 is the mobility scale that second workpiece 6 allows.V-arrangement eccentric wheel 2 rotation urging process is tranquil without impacting, and noiseless produces.Second workpiece 6 by after tight also by position that whether the axial location labeled slots 4 on locating shaft 1 check second workpiece 6 position location requiring.
