Description

Automotive back door is measured cubing

Technical field

The utility model relates to a kind of cubing, the particularly cubing of measured automobiles back door assembly in the component of machine field of measuring technique.

Background technology

Along with the competition of automobile industry constantly aggravates, each automobile vendor constantly releases new model, and " face " changes the fastest before and after the automobile.At present, the detection method of measurement bracket retaining element+large-scale three coordinate measuring machine is generally adopted in the detection of automotive back door, about more than 200 ten thousand yuan of disposable input, annual about 100,000 yuan of maintaining expense, this mode measuring period is long, cost is high, and can't realize the instant detection of production line, can't immediately monitoring to part quality.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of automotive back door to measure cubing, detects cost to reduce, and guarantees that production line back door assembly detects and the promptness of feedback.

The technical scheme that the utility model is dealt with problems is: on the base plate of Tape movement wheel the cubing body is housed, cubing body upper surface is the detection reference face, locating piece and rest pad are equipped with in the inboard of detection reference face, locating shaft is housed on the locating piece, dial gauge detects packaged on the detection reference face, and can move thereon, dial gauge sealing surface measuring mechanism is housed on the cubing body.

The bearing of the said dial gauge sealing surface of the utility model measuring mechanism is connected with protective cover plate by web joint, swing arm can be dynamically connected with swing arm pin and protective cover plate, spring is positioned in the hole of protective cover plate, push rod is contained in the upper surface of swing arm, the bottom contacts with swing arm, and it is outstanding outside it to pass protective cover plate, and the bottom of dial gauge contacts with swing arm.

During detection, automotive back door is positioned on the cubing body, detects the data difference of piece detection back door profile and detection reference face with dial gauge and judge whether back door is qualified; The utilization lever principle adopts dial gauge sealing surface measuring mechanism, by the fabricating quality of dial gauge reading change-detection back door sealing surface, with the purpose that realizes product being carried out quality control at production line in real time.

The utility model compared with prior art has the following advantages:

Whether qualified, the detection efficiency height if 1, on same cubing, can detect the profile and the sealing surface of back door assembly quickly and easily simultaneously;

2, the disposable input of cubing of manufacturing a back door only needs about 200,000 yuan, and the maintaining expense is also lower;

3, part is measured on realization line limit at any time, can reduce cost greatly, and quality testing and feedback are in time;

4, the utility model also extends to the detection of full-sized car parts such as other four-door two-lids and gusset.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a stereographic map of the present utility model;

Fig. 2 is the structural principle sketch of dial gauge sealing surface measuring mechanism 9 among Fig. 1.

Embodiment

As shown in Figure 1, base plate 10 has to move takes turns, and can conveniently detect in real time in the production scene; Be welded with cubing body 7 on the base plate 10, cubing body 7 upper surfaces are detection reference face 6, utilize the part digital-to-analogue, use part bound edge face tangent plane method, and measure the reference field of face type with part surface extension face as cubing to the reference field of skew certain distance as the cubing measurement clearance; One side of detection reference face 6 inboards is equipped with locating piece 2 and locating piece 4, and dismountable locating shaft 1 and locating shaft 3 are housed respectively on locating piece 2 and the locating piece 4; Respectively 1 of

rest pad

8 and 12 is equipped with in the corner of the inboard of detection reference face 6, and a rest pad 11 is equipped with at the inside lower end middle part of detection reference face 6; Dial gauge detects piece 5 and is contained on the detection reference face 6, and can move thereon, is used to detect the total forming surface of back door; According to back door assembly structure shape, 8 dial gauge sealing surface measuring mechanisms 9 are housed on the cubing body 7, these 8 dial gauge sealing surface measuring mechanisms 9 are distributed in 8 corners of back door assembly.

When measuring the back door assembly, locating shaft 1 and 3 is taken off in the pan that pierces into assembly, then assembly is placed on location on

cubing locating piece

2 and 4 with locating shaft 1 and 3, can begin to detect assembly after utilizing the deadweight of back door assembly to fit with

rest pad

8,11,12, the gap available gap chi survey measurements and the record of assembly and cubing reference field 6 sides, the available dial gauge detection of the face difference of assembly and cubing piece 5 moves on cubing detection reference face 6 to be measured and record, can judge whether assembly is qualified according to the acceptance criteria of assembly after measuring.

As shown in Figure 2, the bearing 13 of dial gauge sealing surface measuring mechanism 9 is connected with protective cover plate 15 by web joint 14, swing arm 19 usefulness swing arm pins 17 can be dynamically connected with protective cover plate 15, push rod 16 is contained in the upper surface of swing arm 19, the bottom contacts with swing arm 19, and it is outstanding outside it to pass protective cover plate 15, swing arm 19 can be rotated around swing arm pin 17 under push rod 16 effects, spring 18 is positioned in the hole of protective cover plate 15, the bottom of dial gauge 21 contacts with swing arm 19, and dial gauge 21 is connected on the protective cover plate 15 by adjustable nut 20, spring 23, packing ring 22.

Utilize swing arm pin 17 that the profile of sealing surface is changed and be reflected to reading on the dial gauge 21, design, process and to adjust this mechanism very crucial by push rod 16 and swing arm 19 etc.Push rod 16 extreme positions need be offset assembly sealing surface theoretical position during design, and push rod 16 can be sensitive flexible with imitation part deformation trend.This mechanism can be widely used in the face that inconvenience is directly measured on the measured automobiles part.

During measurement locating shaft among Fig. 11 and 3 is taken off in the pan that pierces into assembly, then assembly is placed on location on

cubing locating piece

2 and 4 with locating shaft 1 and 3, utilize the back door assembly to conduct oneself with dignity with beginning to detect assembly after

rest pad

8,11,12 applyings.When sealing surface deviation theory face is following, the assembly bar 16 that down bears down on one, swing arm 19 will be gone up sled, and dial gauge 21 readings are for just; When sealing surface departs from the reason face when above, push rod 16 will be gone up the top assembly, and swing arm 19 will be sunk, and dial gauge 21 readings are for negative.Wherein, spring 18 is given pretightning force of mechanism all the time, the related no gap of assurance mechanism.
