Abstract
The utility model discloses a car door crashproof rod straightness detection apparatus, comprising a workbench and a position-restricted testing fixture. The workbench is slantly arranged, and the position-restricted testing fixture is arranged on the workbench; the workbench and the position-restricted testing fixture form a detection channel for rolling a crashproof rod. The bottom surface of the position-restricted testing fixture and the workbench are parallelly arranged. The height of the detection channel is the sum of a diameter and a straightness tolerance of the crashproof rod; the width of the detection channel is greater than the length of the crashproof rod so that the crashproof rod can roll across the detection channel smoothly. According to the utility model, a height per unit length is restricted so that products with undesirable straightness can be conveniently filtered; a height difference in a diameter direction in a rolling process is straightness; detection processes are convenient, fast and visual, and production efficiency can be raised.
Description
Technical field
The utility model discloses a kind of sedan door crash bar linearity testing apparatus, by International Patent Classification (IPC) (IPC), divides and belongs to Linearity surveying frock class
skillart field.
Background technology
In existing GB or the method for traditional test linearity, generally need to find benchmark, use the round direct or indirect test products of the modes such as projection (as bar or the column) linearity of beating, arrange, method of testing is complicated, testing tool does not have mobility etc., and error is larger, in production scene, be difficult to easy to use.
China document CN201310625957.0 discloses a kind of efficient cylinder Linearity surveying frock, comprise the first slide block, the second slide block and operator's console, on operator's console, arrange and detect seat, on detection seat, design the chute that can cooperatively interact and slide with two slide blocks, by the top two ends from cylinder part on slide block, it is clamped, and can make part with slide block translation, this scenario-frame is relatively simple, but need clamping product and adjust and process, operating more complicated.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of sedan door crash bar linearity testing apparatus, and testing process easily and fast, intuitively, is enhanced productivity.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of sedan door crash bar linearity testing apparatus, comprise workbench and spacing cubing, workbench wherein tilts to put, spacing cubing is placed on workbench and both form the sense channel that crash bar rolls across, bottom surface and the workbench of spacing cubing be arranged in parallel, the height of sense channel is diameter and the linearity tolerance sum of crash bar, wherein the width of sense channel be greater than crash bar length so that crash bar roll across smoothly.
Further, described spacing cubing two ends are connected with workbench assembling by regulating block, regulating block wherein can change to adjust the channel height between spacing cubing and workbench, and wherein passage is greater than 1.5 times of crash bar girth along the length of crash bar rotating direction.
Further, described spacing cubing can be limited block or position-limited rack, and its bottom surface is the plane parallel with worktable.
Further, described position-limited rack is to consist of cubing frame by front and back support and some limiting plates being connected, the bottom surface of each limiting plate is in the same plane and form sense channel with workbench, and front and back support two ends are installed in the draw-in groove arranging on regulating block and position.
Further, mounting seat under described workbench, this base makes pick-up unit be oblique structure to the other end by reducing gradually by one end.
The utility model is to utilize the limitation in height of per unit length (i.e. length between two limited blocks) conveniently to screen the undesirable product of linearity, product need be between spacing cubing and workbench rolling distance be greater than 1.5 times of girth, rolling process diametric(al) difference in height is linearity, has rational in infrastructure, detection efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model vertical view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 to Fig. 3, a kind of sedan door crash bar linearity testing apparatus, comprise workbench 1 and spacing cubing 2, workbench 1 wherein tilts to put, spacing cubing 2 is placed on workbench and both form the sense channel 100 that crash bar rolls across, bottom surface and the worktable of spacing cubing 2 be arranged in parallel, the diameter that the height of sense channel 100 is crash bar and linearity tolerance sum, wherein the width of sense channel be greater than crash bar length so that crash bar roll across smoothly.Spacing cubing of the present utility model 2 two ends are connected with workbench 1 assembling by regulating block 3, regulating block 3 wherein can change to adjust the channel height between spacing cubing and workbench, and wherein passage is greater than 1.5 times of crash bar girth along the length of crash bar rotating direction.Described spacing cubing 2 can be limited block or position-limited rack, and its bottom surface is the plane parallel with worktable.
Refer to Fig. 1 to Fig. 3, position-limited rack of the present utility model is to consist of cubing frame by front and back support 21,22 and some limiting plates being connected 23, the bottom surface of each limiting plate is in the same plane and form sense channel 100 with workbench, and front and back support 21,22 two ends are installed in the draw-in groove arranging on regulating block 3 and position.1 time mounting seat of workbench of the present utility model or cushion block, can be by connections such as bolts, and base makes pick-up unit be oblique structure to the other end by reducing gradually by one end.
The linearity that the utility model can complete before and after the thermal treatment of all length bar series products is confirmed, it is the limitation in height with per unit length (i.e. length between two limited blocks), confirm whether product meets the structure of the requirement of linearity, testing process easily and fast, intuitively, is enhanced productivity.
Part reprocessing after the utility model completes each welding by drawing, assembling, by upper and lower two assemblies (spacing cubing 2 and workbench 1), upper and lower two assemblies are gone up respectively to three coordinate measuring accuracies, confirm that cubing equipment meets after accuracy requirement, in production scene, upper and lower two assemblies and cushion block (regulating block) are assembled again by bar footpath and linearity requirement, got final product the linearity of reference test bar series products.
The utility model job description:
According to the different size of product and for tolerance different cushion block (regulating block 3) install.As 30 crash bar M, linearity tolerance is 1.0, selects suitable cushion block to make height control from base plate to limited block to 31mm, and limited block (limiting plate 23) shortest length is crash bar girth twice.After installation, can test product linearity.Crash bar after thermal treatment is completed is from a Free-rolling of limited block (retrieval path 10 0) to other end, and in process, crash bar blocks without limited, illustrates that product linearity meets the requirements.
