Problems solved by technology

[0003] At present, most domestic turbocharger bonnet shafts and crank joints are welded by manual positioning tooling for argon arc welding. The automation efficiency is low and the welding quality is not high.
At the same time, because the workpiece needs to be manually clamped, there are certain safety hazards. With the continuous increase of labor costs and the continuous strengthening of safety production requirements, the above-mentioned welding processing scheme is no longer suitable for modern auto parts production, and more efficient and safe processing needs to be explored. method

Embodiment 1

[0044] First, a necessary introduction to the workpiece component 1 to be processed is given, see Figure 10 As shown, the workpiece assembly includes a volute body 12 , a valve cover shaft 13 , and a crank 14 . The valve cover rotating shaft 13 is installed in the bushing hole of the volute body, and the crank 14 is installed on the head of the valve cover rotating shaft 13 and is flush.

[0045] likefigure 1 As shown, an automatic positioning tool for the rotating shaft and crank of a turbocharger mainly includes: a tooling table assembly 2, a main positioning assembly 3, a rotary positioning and pressing assembly 4, a body pressing assembly 5, a rotating shaft jacking assembly 6, a rotating shaft pressing Tightening assembly 7, crank positioning assembly 8, crank pressing assembly 9, crank pressing assembly 10;

[0046] Combined with removal part assembly Figure 4 , 6 As shown, the tooling table assembly 2 includes a tooling table; preferably, the surface contour of the...

Embodiment 2

[0057] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that the structure of the shaft jacking assembly 6 is an auxiliary support block 20, the structure is an inverted T shape, the bottom edge is in contact with the outer surface of the workpiece assembly 1, the upper part is bent inward, and the The top end is in contact with the lower end surface of the valve cover rotating shaft 13 to complete the positioning of the valve cover rotating shaft 13 in the vertical direction.

[0058] Installation process

[0059] Firstly, the volute body 12 is axially positioned by the main positioning assembly 3, secondly, the angular positioning and placement is carried out by the rotating positioning and pressing assembly 4, and then the volute body 12 is pre-compressed by manually pushing the body pressing assembly 5, and then the drive unit makes The body pressing component 5 is pressed, and finally the cylinder is pressed by the rotating positioning...

Abstract

The invention discloses an automatic positioning tool for a rotating shaft and a crank of a turbocharger. , crank pressing component, crank pressing component; all components are installed on the tooling table component, and the workpiece component to be processed is sleeved on the main positioning component; the rotating positioning pressing component abuts the circumference of the workpiece component the side surface of the body pressing component against the side surface of the workpiece component; the rotating shaft jacking component, the rotating shaft pressing component, and the rotating shaft pressing component fix the position of the valve cover rotating shaft; the crank positioning component, the crank pressing component The assembly and the crank pressing assembly fix the position of the crank; the advantage of the invention is that it realizes rapid automatic positioning and clamping of the workpiece, which not only reduces the labor intensity, but also improves the production efficiency, and the operation is simple, convenient, safe and practical, and is more suitable for the production of modern auto parts. .

Description

technical field [0001] The invention relates to the technical field of automatic tooling, in particular to an automatic positioning tooling for a rotating shaft and a crank of a turbocharger. Background technique [0002] The turbocharger is an air compressor, which increases the intake air volume of the engine by compressing the air, which can significantly improve the engine performance. The common form is to use the inertial impulse of the exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to pressurize it into the combustion chamber. In actual operation, the supercharged intake is not performed when the engine is started, so the turbocharger needs to be equipped with a regulating device to directly remove the exhaust gas when supercharging is not required (for example, in the idling stage). The common regulating device is the intake air. A ven...
