Problems solved by technology

The sensor shaft is used not only as a rotating connection but also as a signal output, and the structure is more complicated
[0003] The existing suspended accelerator pedal sensor shaft is assembled manually. During the assembly process, because the throttle spring acts on the head of the throttle connecting rod, it takes a lot of effort to put the sensor of the throttle connecting rod into place during manual assembly. The shaft hole is aligned with the upper hole and the lower hole of the base, and the operation is difficult; in addition, during the press-fitting process, since the throttle base has two layers of holes, when the sensor shaft passes through the upper hole of the base and the sensor shaft hole of the throttle connecting rod, the spring Under the action of force, the sensor shaft is in a tilted state. Manually, the tilted sensor shaft needs to be pulled hard to align it with the bottom hole of the base before it can be pressed into it. Assembly is more difficult, and the sensor shaft is easily broken.

Embodiment approach 1

[0040] see figure 1 , this embodiment provides a suspension type accelerator pedal sensor shaft installation device for press-fitting the sensor shaft 5 into the accelerator pedal (the accelerator base 6 and the accelerator link 7), including a base plate 3, a pressing mechanism 1, a placement device Mechanism 2 and side push mechanism 4.

[0041] see Figure 2 to Figure 4 , the pressing mechanism 1 includes a servo electric cylinder 10 , a gantry, a floating head 13 , an L-shaped plate 14 , a pressing head seat 15 , a pressing head 16 , a linear guide 19 and a guide plate 18 .

[0042] The gantry frame is composed of a gantry board 11, a profile 12 and a profile seat 17. The two profiles 12 are arranged in parallel under the two sides of the gantry board 11, and the lower ends are respectively inserted into the slots of the profile seat 17; the servo electric cylinder 10 is installed vertically Just above the gantry plate 11 , the extension rod of the electric cylinder goes...

Embodiment approach 2

[0056] see figure 1 and Figure 12 , this embodiment provides a method for using the accelerator sensor shaft installation device as described in Embodiment 1, which is characterized in that it includes the following steps:

[0057] The first step is to place the loose electronic throttle assembly into the product positioning device 2, so that the lower side of the throttle base 6 fits the contoured surface 2130, the lower hole 64 of the throttle base 6, the sensor shaft hole of the throttle link 7, the throttle The upper hole 63 of the base 6 passes through the positioning post 210 in turn, and the technological hole 70 of the accelerator connecting rod 7 is inserted into the rotating pin 22; the compression cylinder 21 is activated, the cylinder piston rod retracts, and the pressure head 22 moves downward to contact the throttle base 6. On the upper side, press the throttle base 6 on the profiling surface 2130;

[0058] The second step is to start the dual-axis cylinder 46...

Abstract

The invention discloses a suspension type accelerator pedal sensor shaft mounting device and method. The suspension type accelerator pedal sensor shaft mounting device comprises a base plate, a press fitting mechanism, a placing mechanism and a side pushing mechanism. The press-fitting mechanism is arranged right above the base plate, is in a portal frame form and is used for press-fitting the sensor shaft; the placing mechanism is arranged above the base plate and in the middle of the press-fitting mechanism and is used for fixing the electronic throttle bulk parts; the side pushing mechanism is arranged on the front portion of the upper portion of the placing plate and used for pushing a pedal below the electronic accelerator spare parts. The accelerator sensor shaft can be conveniently, efficiently, stably and safely mounted, the product quality is effectively improved, the workload of workers is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic accelerator pedal installation, in particular to a suspension type accelerator pedal sensor shaft installation device and method. Background technique [0002] A displacement sensor is installed on the accelerator pedal of the electronic accelerator. When the driver steps on the accelerator pedal, the ECU will collect the opening change and acceleration of the displacement sensor on the pedal, judge the driver's driving intention according to the built-in algorithm, and then send the throttle valve to the engine. The control motor sends corresponding control signals to control the power output of the engine. The sensor shaft serves as both a rotating connecting piece and a signal output piece, and the structure is relatively complicated. [0003] The existing suspended accelerator pedal sensor shafts are all assembled manually. During the assembly process, since the accelerator spring acts on ...
