Problems solved by technology

[0003] 1. Each type of pedal requires a special fixture, and the versatility of the test device is poor, thus increasing the test cycle and cost
[0004] 2. The loading force of the universal testing machine is relatively large, and the load required for the lateral static strength of the pedal is small, generally below 50KG, which feels like a big horse-drawn cart, which not only wastes power, but also has accurate test results Poor degree

Embodiment 1

[0042] like image 3 As shown, the cylinder 6 of the present invention is located on the cylinder mounting plate 7, and is connected by a threaded coupling; the piston movement direction of the cylinder 6 is the transverse direction of the described automobile pedal; the cylinder mounting plate 7 The upper hole for installing the cylinder 6 is a waist-shaped hole, and the length direction of the waist-shaped hole is perpendicular to the moving direction of the piston of the cylinder 6 .

[0043] Two long waist-shaped holes have been opened on the cylinder mounting plate 7, so that the size of the cylinder block of the cylinder 6 can be adjusted perpendicular to the moving direction of the cylinder 6 pistons. The direction is figure 1 in the horizontal direction, in figure 2 Middle is the up and down direction.

[0044] The piston stroke of the cylinder 6 realizes the size adjustment in its direction of motion. exist figure 2 and image 3 Both are left and right directi...

Embodiment 2

[0046] like Figure 4 As shown, the test piece 8 of the present invention is arranged on the test piece mounting plate 1, and is connected by a threaded coupling; hole.

[0047] Mounting holes for various pedals are drilled on the test piece mounting plate 1 for adjusting the height direction dimensions of various pedals.

[0048] The test piece 8 is directly fixed on the test piece mounting plate 1 with hexagonal bolts, and no special fixtures need to be designed and manufactured.

[0049] Through the above embodiment, the size of the test piece 8 in three directions of space can be adjusted, and can adapt to the geometric dimensions of different pedals, that is to say, the test device provided by the present invention can be suitable for the transverse static strength test of a series of pedals.

Embodiment 3

[0051] like figure 1 As shown, the pneumatic device of the present invention is provided with a pressure gauge 4 .

[0052] Setting the pressure gauge 4 can monitor the working pressure of the air pressure system, and adjust the pressure of the system according to the indication of the pressure gauge.

[0053] Below is the test method of automobile pedal static strength testing device of the present invention, and its purpose of the invention is identical with above-mentioned technical scheme. The procedure for this test method is:

[0054] like Figure 1 to Figure 4 Shown:

[0055] Install the test piece 8 on the test device, adjust the position of the test piece 8 on the test piece mounting plate 1, and when adjusted to a suitable position, fasten the test piece 8;

[0056] Adjust the position of the cylinder 6, and tighten the cylinder 6 when the position is appropriate;

[0057] Turn on the air source 10, adjust the pressure to a specified value according to the specifi...

Abstract

The present invention discloses a test device for static strength of automobile pedal, implementing a static strength test to a test piece (8) which is an automobile pedal by setting a frame (5), the test device is pneumatic and includes an air source (10), a pneumatic triple member (3), an electromagnetic valve (2), an air cylinder (6) and a restrictive valve (9), and the members are connected with each other through gas tube (11). The invention also discloses a test method for the test device. By means of employing the technical scheme, the structure of the device is compact, and the manufacture and usage are all convenient; the test piece is fixed on the device directly by hexagon bolts without design and production of special fixture; the dimension of each direction is adjustable, thus the test device is capable of adapting the physical dimension of different pedal, namely the test device is capable of being suitable for the transversal static strength test of series pedals; the application range is wide and the test device is suitable for various series automobile pedals; the consumed power is small, and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing technology of automobile parts, and relates to the test technology of automobile pedals, more specifically, the invention relates to a static strength test device of automobile pedals. In addition, the present invention also relates to a testing method of the testing device. Background technique [0002] Automobile pedals need to carry out transverse static strength test. At present, the tests for this project generally use special fixtures to fix the pedals on the universal testing machine. Its disadvantages are: [0003] 1. Each type of pedal requires a special fixture, and the universality of the test device is poor, thus increasing the test cycle and cost. [0004] 2. The loading force of the universal testing machine is relatively large, and the load required for the lateral static strength of the pedal is small, generally below 50KG, which feels like a big horse-drawn cart, which no...
