Description
Technical field
The utility model relates to clamping tool for machine work field, especially relates to a kind of novel one side two pin positioning structure.
Background technology
Clamping tool for machine work guarantees that workpiece obtains the required equipment of one of certain machining accuracy in machine tooling process by clamping device and location facilities.Because test specimen has 6DOF, in order to ensure that machining accuracy meets design tolerance requirement, one side and two finger settings are usually adopted to obtain machining benchmark.In batch production process, especially for large-scale workpiece, in test specimen and Fixture assembly, position fixing process, locating hole and alignment pin are difficult to realize dynamic auto cooperation assembling, in pin of being everlasting, hole cooperation assembling process, occur that alignment pin fractures, if coordinated by human assistance calibration, labour intensity is large, production efficiency is low, so just causes larger impact to clamping positioning technology in System for Large-scale Specimen process.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses the reciprocal transmission system of a kind of vehicle body soldering [application number: 2014105012753], in order to the orientation problem of reciprocal guide rail mechanism in the repeat system that realizes being welded, system utilizes controller control electronic control cylinder to make its telescopic alignment pin insert in guide, and be mated, ensure that guide rail rests on initial position, after having welded, controller controls electronic control cylinder makes its telescopic alignment pin retract, be separated with set pin sleeve, realize guide rail and welding work pieces moves to next station under motor drives.Such scheme to some extent solve in the finger setting of existing one side two sell, hole assembly difficulty is large, easily occur to sell the problem fractureed, but the program still also exists: auxiliary body is too much, the problems such as position stability is poor, and precision is low.
Summary of the invention
In order to overcome the deficiency of existing one side two pin positioning structure, the utility model provides novel one side two pin positioning structure that a kind of stability is better, Position location accuracy is higher.
The utility model solves the technical scheme that its technical problem adopts:
A kind of novel one side two pin positioning structure, described location structure comprises by positioning workpieces, pedestal and alignment pin, describedly be positioned on described pedestal by positioning workpieces, the described bottom surface by positioning workpieces is provided with the locating hole with described detent fit, the epimere of described locating hole is cylindrical hole, the hypomere of described locating hole is the conical bore in order to alignment pin guiding, described conical bore is communicated with described cylindrical hole, described alignment pin comprise in order to by the straight pin of positioning workpieces located lateral and in order to by positioning workpieces circumference location rhombus pin, the bottom of described straight pin and the bottom of described rhombus pin are all fixed on described pedestal, the top of described straight pin and the top of described rhombus pin are spherical.
The beneficial effects of the utility model are mainly manifested in: alignment pin can centering rectification within the specific limits when pressure effect, and prevent from being occurred in positioning workpieces and Fixture assembly offseting, fracture alignment pin, and meanwhile, stability is better, and Position location accuracy is higher.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of novel one side two pin positioning structure.
Fig. 2 is the structural representation of straight pin.
Fig. 3 is the structural representation of rhombus pin.
Fig. 4 is by the locating hole structural representation of positioning workpieces.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 4, a kind of novel one side two pin positioning structure, described location structure comprises by positioning workpieces 3, pedestal 4 and alignment pin, describedly be positioned on described pedestal 4 by positioning workpieces 3, the described bottom surface by positioning workpieces 3 is provided with the locating hole 5 with described detent fit, the epimere of described locating hole 5 is cylindrical hole 51, the hypomere of described locating hole 5 is the conical bore 52 in order to alignment pin guiding, described conical bore 52 is communicated with described cylindrical hole 51, described alignment pin comprise in order to by the straight pin 2 of positioning workpieces 3 located lateral and in order to by positioning workpieces 3 circumference location rhombus pin 1, the bottom of described straight pin 2 and the bottom of described rhombus pin 1 are all fixed on described pedestal 4, the top of described straight pin 2 and the top of described rhombus pin 1 are spherical.
In the present embodiment, the end face of described pedestal 4 is plane and is fitted by the bottom surface of positioning workpieces 3.
As shown in Figure 1, positioning workpieces 3 is had the locating hole 5 of band conical surface guiding, the conical surface generation linear contact lay of the spherical head of alignment pin and the conical bore 52 of locating hole 5 hypomere when practical set.Along with moving down by positioning workpieces 3 under the effect of pressure (weight) power, in certain deviation region, the spherical head of alignment pin can along the conical surface slippage of linear contact lay, final alignment pin slides in the locating hole of cooperation completely, thus realize by the transverse direction of positioning workpieces 3 and circumference location, prevent from being occurred offseting by positioning workpieces 3 and Fixture assembly, fracture alignment pin.
As shown in Figure 2, it is spherical that straight pin 2 in the utility model and general cylindrical pin difference are that its head is processed into, when practical set and the conical surface of locating hole 5 match, because the conical surface of sphere and conical bore 52 is linear contact lay, at the centering rectification that certain pressure (weight) power effect is carried out to a certain extent.
As shown in Figure 3, rhombus pin 1 is divided into three parts, and bottom 13 is column type, and middle part 12 is rhombus, and top 11 is spherical.Be spherical top with common rhombus pin difference, when practical set and the conical surface of the conical bore 52 of locating hole 5 hypomere match, and form linear contact lay, can by applying the centering rectification that certain pressure effect is carried out to a certain extent, meanwhile, good stability, Position location accuracy is high.
Specific embodiment described in the utility model is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.Although more employ by terms such as positioning workpieces 3, straight pin 2, rhombus pins 1, do not get rid of the possibility using other term herein.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
