In the technical scheme, a laser device and a laser target which are fixedly connected with measured points of the left and right longitudinal beams are adopted, and the coaxiality situation of the left and right longitudinal beams is detected by measuring a target spot position of the laser device. The device is characterized by consisting of a transmitting unit and a display unit, wherein the transmitting unit consists of a magnetic seat and a laser transmitter fixed on the magnetic seat, and the display unit consists of a magnetic seat and a laser display plate fixed on the magnetic seat. The method and the device can conveniently and effectively achieve the detection of the coaxiality of the left and right longitudinal beams of the automobile frame assembly, detection of different hole diameters can be achieved by replacing a measuring-positioning pin, the universality is achieved, manpower and material resources are reduced, and an assembly process and the product quality of a finished automobile are ensured.
Description
?
Technical field
The online test method and the device that the invention discloses a kind of frame assembly left-right longeron right alignment of heavy truck, belong to vehicle frame production testing technical field.
Background technology
The vehicle frame of heavy-duty car is one of assembly of car load most critical.It is the general assembly benchmark such as engine, pilothouse, vehicle bridge, front and back leaf spring, fuel tank, battery box, is again the supporting body of bending stress and the twisting stress that brake hard occurs of vertical direction, is commonly called as " iron and steel spine ".The structure of car load and stress in service have determined that frame assembly will have the reliability of the accurate accuracy of form and position and height.But frame assembly self integrates left-right longeron, crossbeam assembly, by somely rushing weldment, rivet welding part is combined, the factors such as stress, cumulative errors and distortion have wherein affected frame assembly total quality.
For promoting quality, heavy truck general dress that uses when Frame Assembling closes mold, while assembling on mold, can to frame assembly left-right longeron, force to proofread and correct by mold, guarantees accuracy requirement.But after frame assembly rolls off the production line, due to factors such as the resilience of rivet welding part, the internal stresses releases of left-right longeron, cause the frame assembly right alignment after rolling off the production line to occur subtle change, need to the vehicle frame left-right longeron right alignment that roll off the production line be inspected by random samples and be followed the tracks of, to guarantee the quality index of frame assembly.But traditional measuring equipment and method, cannot detect the right alignment of frame assembly.Therefore, for the vehicle frame left-right longeron right alignment that rolls off the production line, inspect by random samples and follow the tracks of, be industry technical task to be solved and that never solve in mid-term always.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of detection method and device of automobile frame left-right longeron right alignment is provided.
Technical scheme of the present invention is to adopt the laser instrument and the laser target that are fixedly connected with left and right longeron measured point, by measuring the target position of laser instrument, detects the right alignment situation of left and right longeron.
A pick-up unit for the left and right longeron right alignment of automobile frame, is characterized in that being comprised of transmitter unit and display unit two parts.
Transmitter unit is comprised of magnet base and the generating laser being fixed on magnet base.
The laser beam of generating laser and the dead in line of magnet base.
Above magnet base, there is the pin-and-hole being connected with measurement and positioning pin.
The axle of pin-and-hole and the dead in line of magnet base.
Display unit is comprised of magnet base and the laser display dish being fixed on magnet base.
The concentric circles scale that laser display Pan Shangyouyi laser display disk center is the center of circle.
The centres of laser display Pan center and magnet base.
Above magnet base, there is the pin-and-hole being connected with measurement and positioning pin.
The axle of pin-and-hole and the dead in line of magnet base.
When this pick-up unit is used, behind the Kong Weiyong canonical measure register pin location that transmitter unit and vehicle frame right vertical beam need be detected, with magnet base absorption clamping, generating laser Emission Lasers ray, measurement and positioning finger setting is also used in the position, hole that display unit is corresponding with left longeron, after magnet base absorption, according to laser beam, be irradiated to the position of laser display dish, the deviation before and after record.Convenient, fast, only need 1 people to operate.Meanwhile, be not subject to the impact of longeron length, height and environment, all can measure at any time, be convenient to the case study of rear operation assembling.Meanwhile, the standard setting pin of A1 size can be changed according to the size in measured aperture, is adapted to the measurement of different pore size.
In sum, the detection method of the left and right longeron right alignment of a kind of automobile frame, is characterized in that:
In the measured hole of left and right longeron, lay measurement and positioning pin, measurement and positioning pin coordinates with the pin-and-hole of the magnet base of transmitter unit and display unit respectively, and transmitter unit and display unit are positioned on the measured hole of left and right longeron;
Transmitter unit gives off laser beam to display unit, on the laser display dish of display unit, forms luminous point;
Measure the distance of luminous point and laser display disk center, obtain the result of left-right longeron right alignment.
The present invention can make easily and effectively the right alignment of the left and right longeron of frame assembly detect and obtain realization, and the detection for different pore size can realize by changing part measurement and positioning pin, reach versatility, reduced human and material resources, guarantee assembly technology and the product quality of car load.
