Description

Technical Field

[0001] The invention relates to the technical field of automobile gap detection, and more specifically to a vehicle chassis moving parts gap measuring device. Background Art

[0002] Among the many structural systems of a car, the vehicle chassis transmission system, driving system, steering system and braking system are important components of the vehicle. The entire chassis system has many parts, which are often connected by bolts, rubber and other means. In addition, many parts such as the triangular arm, half shaft, steering gear and other parts are moving parts, and the chassis moving parts belong to spatial movement. During the operation of the vehicle, if there is interference with each other, it will cause abnormal noise at the least, and even breakage in severe cases. Many factors such as unreasonable chassis design, loose connection of parts, insufficient clamping force, increased gap after aging, and wear of parts may cause collision or friction between chassis parts, resulting in abnormal noise.

[0003] However, in the process of automobile development, common verification methods for spatial motion components include simulation software verification and vehicle verification; simulation software verification can quickly and conveniently verify the motion between components, but it only simulates mechanical motion and cannot simulate the actual deformation of components under stress, such as the deformation of rubber parts and wiring harnesses. Vehicle verification can accurately verify the motion between components, but due to space limitations, the gaps between some components can only be visually observed and cannot be accurately measured; if the status of a component changes, it must be replaced on the vehicle for verification, which has poor operational convenience and timeliness, and occupies R&D vehicle resources and is costly.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0030] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] like Figures 1 to 5 As shown, an embodiment of the present invention provides a vehicle chassis moving parts clearance measuring device, comprising: a workbench 1, a positioning assembly 2 and a lifting assembly 3. The workbench 1 has sufficient rigidity to support the entire chassis component 5 to be measured and the positioning assembly 2.

[0032] The positioning assembly 2 is arranged on the workbench 1, and the positioning assembly 2 is used to fix the chassis component 5 to be tested. The chassis component 5 to be tested is assembled from real vehicle chassis parts, and parts can be added or reduced according to measurement requirements.

[0033] The lifting assembly 3 includes a lifting mechanism 31 and a connecting mechanism 32. The lifting mechanism 31 is arranged on both sides of the workbench 1. The connecting mechanism 32 is connected to the lifting mechanism 31, and the connecting mechanism 32 is used to fix both sides of the chassis component 5 to be tested. The connecting mechanism 32 includes a connecting plate 321, a first fixing plate 322 and a second fixing plate 323. The connecting plate 321 is connected to the lifting mechanism 31, the first fixing plate 322 is fixed on the connecting plate 321, the second fixing plate 323 is vertically connected to the first fixing plate 322, and the second fixing plate 323 is connected to the wheels of the chassis component 5 to be tested. In the working state, the lifting assembly 3 drives the connecting plate 321 to rise or fall, so that the wheels of the chassis component 5 to be tested rise to the highest position, or fall to the lowest position, and measure the gaps between the various components in the chassis component 5 to be tested.

[0034] Specifically, the first fixing plate 322 and the second fixing plate 323 form an L-shaped structure.

[0035] During operation, the operator first places the chassis component 5 to be tested on the fixing assembly, and limits the chassis component 5 to be tested by the fixing assembly.

[0036] Next, the second fixing plate 323 is connected to the wheel of the chassis component 5 to be tested, and the lifting mechanism 31 drives the connecting plate 321 to rise or fall, so that the connecting plate 321 drives the first fixing plate 322 and the second fixing plate 323 to rise or fall, thereby driving the wheel of the chassis component 5 to be tested to rise to the highest position, or to fall to the lowest position, so as to simulate the operating state of the chassis component 5 to be tested during vehicle driving.

[0037] Next, the operator visually determines the gap state between the components in the current state, measures the gaps between the components in the chassis component 5 to be tested, and records the measurement data. The present invention enables the operator to quickly measure the gaps between the components in the chassis component 5 to be tested during the research and development process, and provides a basis for the lean measurement of the boundary design of the components in the chassis component 5 to be tested. The structure is simple and easy to operate, and the gaps between the components in the chassis component 5 to be tested can be quickly measured, and the structural strength and stiffness of the components of the chassis component 5 to be tested can also be detected when the chassis component 5 to be tested is rising or falling.

[0038] The present invention arranges the positioning assembly 2 on the workbench 1, the lifting mechanism 31 is arranged on both sides of the workbench 1, the connecting mechanism 32 is connected to the lifting mechanism 31; the connecting plate 321 is connected to the lifting mechanism 31, the first fixing plate 322 is fixed on the connecting plate 321, the second fixing plate 323 is vertically connected to the first fixing plate 322, and the second fixing plate 323 is connected to the wheel of the chassis component 5 to be tested; when working, the operator first places the chassis component 5 to be tested on the fixing assembly, and limits the chassis component 5 to be tested by the fixing assembly; then, the second fixing plate 323 is aligned with the wheel of the chassis component 5 to be tested. The lifting mechanism 31 is connected and drives the connecting plate 321 to rise or fall, so that the connecting plate 321 drives the first fixing plate 322 and the second fixing plate 323 to rise or fall, thereby driving the wheels of the chassis component 5 to be tested to rise to the highest position, or fall to the lowest position, so that the operator can quickly measure the gaps between the various components in the chassis component 5 to be tested during the research and development process, providing a basis for the lean measurement of the boundary design of the various components in the chassis component 5 to be tested, avoiding the problem of abnormal noise caused by excessive or small gaps between the chassis components during driving of the vehicle, and improving the research and development efficiency and accuracy.

[0039] In one embodiment of the vehicle chassis moving parts clearance measuring device of the present invention, as Figures 1 to 4 As shown, a plurality of waist-shaped holes 324 are provided on the second fixing plate 323 , and the plurality of waist-shaped holes 324 are arranged in a circumference. Fastening bolts are installed in the plurality of waist-shaped holes 324 so that the wheel of the chassis component 5 to be tested is fixed on the second fixing plate 323 .

[0040] Specifically, the waist-shaped hole 324 can be used to match the wheel rim pitch circle and wheelbase of different vehicle models. The diameter of the adapted pitch circle range is 100-140 mm, and the adapted wheelbase range is 1500-1800 mm, thereby being able to fix chassis components 5 to be tested of different models.

[0041] The present invention provides a plurality of waist-shaped holes 324 on the second fixing plate 323, and arranges the plurality of waist-shaped holes 324 in a circular arrangement, and installs fastening bolts in the plurality of waist-shaped holes 324, so that the wheel of the chassis component 5 to be tested is on the second fixing plate 323, and the second fixing plate 323 can be stably connected to the wheel of the chassis component 5 to be tested, so that the second fixing plate 323 can stably drive the chassis component 5 to be tested to rise or fall when rising or falling.

[0042] In one embodiment of the vehicle chassis moving parts clearance measuring device of the present invention, as Figures 1 to 4As shown, the lifting mechanism 31 includes a base 331, a handle 332, a screw rod 333, a worm gear and an outer tube 334.

The handle 332 is arranged outside the outer tube 334, and the handle 332 is connected to the worm gear.

[0043] Specifically, when the lifting mechanism 31 is required to drive the chassis component 5 to be tested to rise or fall, the operator first acts on the handle 332, and rotates the handle 332 to drive the worm gear to rotate. The rotation of the worm gear drives the screw rod 333 engaged therewith to move upward or downward, and then drives the connecting plate 321 connected to the screw rod 333 to move upward or downward, thereby driving the chassis component 5 to be tested to rise or fall.

[0044] The present invention converts circular motion into linear motion by designing the structure of the handle 332, the screw rod 333, and the worm gear, so that the operator can use a relatively small force to drive the chassis component 5 to be tested to rise or fall.

[0045] In one embodiment of the vehicle chassis moving parts clearance measuring device of the present invention, as Figures 1 to 4 As shown, in order to accurately control the movement of the chassis component 5 to be tested, a scale 335 is provided on the outer wall of the outer tube 334 so that the operator can accurately read the scale 335 to improve the accuracy of the displacement of the screw rod 333.

[0046] In one embodiment of the vehicle chassis moving parts clearance measuring device of the present invention, as Figures 1 to 5 As shown, the positioning assembly 2 includes a third fixing plate 21, a positioning pin 22 and a support block 23. The third fixing plate 21 is arranged on the workbench 1. The positioning pins 22 are respectively arranged on both sides of the first end of the third fixing plate 21, and the positioning pins 22 are inserted into the chassis component 5 to be tested. The first end of the support block 23 is arranged on the second end of the third fixing plate 21, and the second end of the third fixing plate 21 abuts against the chassis component 5 to be tested.

[0047] Specifically, the positioning pin 22 is rotatably disposed on the third fixing plate 21 so as to be able to be laid down when not in use.

[0048] The third fixing plate 21 is provided with two mounting holes 24 , and the workbench 1 is correspondingly provided with convex bodies, which are inserted into the mounting holes 24 to fix the third fixing plate 21 .

[0049] The present invention arranges the locating pins 22 on both sides of the first end of the third fixing plate 21 respectively, and the locating pins 22 are inserted into the chassis component 5 to be tested, and the first end of the support block 23 is arranged on the second end of the third fixing plate 21, and the second end of the third fixing plate 21 abuts against the chassis component 5 to be tested, so that the chassis component 5 to be tested is positioned by the locating pins 22, thereby avoiding the situation that the two sides of the chassis component 5 to be tested move when being lifted or lowered, and the chassis component 5 to be tested is supported by the support block 23, thereby ensuring the stability of the chassis component 5 to be tested placed on the third fixing plate 21.

[0050] In one embodiment of the vehicle chassis moving parts clearance measuring device of the present invention, as Figures 1 to 5 As shown, the support block 23 includes a first fixing rod 231, a second fixing rod 232 and a support plate 233. The first end of the first fixing rod 231 is connected to the third fixing plate 21, the second end of the first fixing rod 231 is rotatably connected to the first end of the second fixing rod 232, the second end of the second fixing rod 232 is connected to the support plate 233, and the support plate 233 abuts against the chassis component 5 to be tested.

[0051] Specifically, the second fixing rod 232 can be placed vertically or horizontally, and when the support plate 233 does not need to support the chassis component 5 to be tested, the first end of the second fixing rod 232 rotates along the second end of the first fixing rod 231 and is in a flat state. When the second fixing rod 232 is placed vertically, it is fixed by a pin to prevent the support plate 233 from rotating when supporting the chassis component 5 to be tested.

[0052] In one embodiment of the vehicle chassis moving parts clearance measuring device of the present invention, there are a plurality of support blocks 23 , and the plurality of support blocks 23 are arranged at intervals at the second end of the third fixing plate 21 .

[0053] The present invention arranges a plurality of support blocks 23 at intervals at the second end of the third fixing plate 21, and the support block 23 is located on one side of the third fixing plate 21, so that the two ends of the third fixing plate 21 are supported and limited by the support blocks 23 and the positioning pins 22 respectively, thereby effectively ensuring the stability of the placement of the chassis component 5 to be tested.

[0054] In addition, by disposing a plurality of support blocks 23 at intervals at the second end of the third fixing plate 21 , different chassis components 5 to be tested can be matched.

[0055] In one embodiment of the vehicle chassis moving parts gap measuring device of the present invention, the positioning assembly 2 also includes a connecting rod and a fixed block, the connecting rods are respectively arranged on the side walls of the third fixed plate 21, and the connecting rods are connected to the fixed block, and the fixed block has a card interface, which is card-connected to the chassis component 5 to be measured.
