Description

Technical Field

[0001] The utility model relates to the technical field of automobile tooling, and more specifically to an air tightness measuring and oiling tooling. Background Art

[0002] The torsion beam components of the automobile chassis are relatively large, which can be simply described in three sections, namely the left trailing arm semi-assembly, the right trailing arm semi-assembly, and the middle crossbeam. NVH is the abbreviation of noise, vibration, and harshness (Noise, Vibration, Harshness), which is a comprehensive issue to measure the quality of automobile manufacturing. It gives the most direct and superficial experience to automobile users. The NVH problem of vehicles is one of the issues that major vehicle manufacturers and parts companies in the international automobile industry are concerned about. In order to optimize NVH, it is necessary to inject anti-wear oil into the inner cavity of the middle automobile torsion beam and the crossbeam to reduce friction noise during use. Before oiling, in order to prevent leakage due to poor sealing performance of the oil filling port, it is also necessary to test the air tightness.

[0003] In the prior art, both the air tightness detection and oil filling processes are done manually. This is inefficient and the workload on workers is heavy. Since both the air tightness detection and oil filling processes are manually operated by operators without automatic equipment, and the process is guaranteed to be confirmed as Class B, there will be the following two problems: 1. There are missed detections during the air tightness detection process, and defective parts may not be detected, which eventually leads to the outflow of defective parts and oil leakage; 2. There are missed fillings in the oil filling process, which eventually leads to market complaints about abnormal noises in the whole vehicle, affecting the quality of the product. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an air tightness measuring and oil filling tool, which is provided with a movable air tightness detection mechanism and an oil filling mechanism. When the automobile cross beam and the torsion beam are fixed, the air tightness detection mechanism and the oil filling mechanism can automatically complete the two processes of air tightness detection and oil filling in sequence.

First, the moving mechanism moves the airtight detection mechanism so that the airtight detection mechanism is aligned with the oil filling port of the automobile torsion beam and crossbeam, and the airtight detection mechanism extends into the oil filling port.

[0022] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0023] Example 1

[0024] like Figure 1As shown, a gas tightness measuring and oil filling tool is characterized in that it includes a base plate 1, a clamping assembly 2 for clamping a car cross beam and a torsion beam, a moving mechanism 3 moving in the XY direction, an airtightness detection mechanism 4 moving in the Z direction, and an oil filling device 5 moving in the Z direction, wherein the clamping assembly is mounted on the base plate 1; the moving mechanism 3 is mounted on the base plate 1, and the airtightness detection mechanism 4 and the oil filling mechanism 5 are respectively mounted on the moving mechanism 3. The automobile torsion beam and the cross beam are fixed to the base plate by the clamping assembly 2 to ensure that the automobile torsion beam and the cross beam are in a suitable position and will not be offset, so as not to affect other processes. The moving mechanism 3 moves the airtightness detection mechanism 4 and the oil filling mechanism 5 to a suitable position. First, the moving mechanism 3 moves the airtightness detection mechanism 4 so that the airtightness detection mechanism 4 is aligned with the oil filling port of the automobile torsion beam and the cross beam, and the airtightness detection mechanism 4 extends into the oil filling port. When the airtightness detection mechanism 4 detects that the oil filling port meets the airtightness standard, the airtightness detection mechanism 4 extends from the oil filling port, and the moving mechanism 3 moves so that the oil filling mechanism 5 is aligned with the oil filling port, and then the oil filling and structure 5 extends into the oil filling port to fill the oil. When the oil filling is completed, the oil filling mechanism 5 closes the oil circuit and extends from the oil filling port, thereby completing the two processes of airtightness detection and oil filling. In the two processes of airtightness detection and oil filling, the airtightness detection and oil filling tooling are completely completed automatically, and no manual operation is required, which ensures the quality of the process while reducing the labor burden of workers.

[0025] like Figure 2 As shown, the moving mechanism 3 includes an X-direction moving component 31 and a Y-direction moving component 32, the X-direction moving component 31 is mounted on the base plate 1, the Y-direction moving component 32 is mounted on the X-direction moving component 31, and the airtight detection mechanism 4 and the oil filling mechanism 5 are mounted on the Y-direction moving component 32. When the automobile cross beam and the torsion beam are fixed, the moving mechanism 3 moves the airtight detection mechanism 4 and the oil filling mechanism 5 to align with the oil filling port. The X-direction moving component 31 can drive the Y-direction moving component 32 and the airtight detection mechanism 4 and the oil filling mechanism 5 to move in the X direction. When the X-direction moving component 31 moves to a suitable position, the Y-direction moving component 32 drives the airtight detection mechanism 4 and the oil filling mechanism 5 to move in the Y direction, so that the airtight detection mechanism 4 and the oil filling mechanism 5 are aligned with the oil filling port.

[0026] like Figure 2As shown, the X-direction moving assembly 31 includes a first slide rail 311, a first telescopic member 312 and a first slide plate 313. The first slide rail 311 is mounted on the bottom plate 1 and arranged along the X direction. The first slide plate 313 is mounted on the first slide rail 311 and is slidably connected to the first slide rail 311. The first telescopic member 312 is mounted on the bottom plate 1 and is parallel to the first slide rail 311. The telescopic end of the first telescopic member 312 is connected to the first slide plate 313. The Y-direction moving assembly 32 is mounted on the first slide plate 313. The first slide plate 313 is slidably connected to the first slide rail 311, and the first slide plate 313 can only move along the length direction of the first slide rail 311, that is, the X direction. The telescopic end of the first telescopic member 312 is connected to the first slide plate 313 to drive the first slide plate 313 to move, thereby realizing the automatic movement in the X direction. The Y-direction moving component 32 is installed on the first slide plate 313 , so that the Y-direction moving component 32 can move in the Y direction based on the X-direction movement of the X-direction moving component 31 , thereby realizing the combination of the X-direction movement and the Y-direction movement.

[0027] like Figure 2 As shown, the Y-direction moving mechanism 32 includes a second slide rail 321, a second telescopic member 322 and a second slide plate 323. The second slide rail 321 and the second telescopic member 322 are arranged in parallel and are installed on the first slide plate 313 along the Y direction. The second slide plate 323 is installed on the second slide rail 321 and is slidably connected with the second slide rail 321. The second slide plate 323 is connected to the telescopic end of the second telescopic member 322. A mounting plate 324 is connected to the second slide plate 323 along the Z direction. The airtight detection mechanism 4 and the oil filling mechanism 5 are installed on the mounting plate 324 along the Z axis. The second slide plate 323 is slidably connected to the second slide rail 321, which limits the second slide plate 323 to move only along the length direction of the second slide rail 321, that is, the Y direction. The telescopic end of the second telescopic member 322 is connected to the second slide plate 323 to drive the second slide plate 323 to move, thereby realizing the automatic movement in the Y direction. The second slide plate 323 is connected with a mounting plate 324 along the Z direction to ensure that the airtight detection mechanism 4 and the oil filling mechanism 5 mounted on the mounting plate 324 can be extended and retracted in the Z direction to ensure that they are aligned with the oil filling port.

[0028] like Figure 2As shown, the airtight detection mechanism 4 includes a third telescopic member 41 and an airtight detection head 42. The airtight detection head 42 is installed at the telescopic end of the third telescopic member 41. The third telescopic member 41 is installed on the mounting plate 324 along the Z direction. The airtight detection head 42 can detect the sealing of the oil filling port of the automobile torsion beam and the cross beam. When detection is required, after the moving mechanism 3 moves to a suitable position, the third telescopic member 41 can extend or withdraw the airtight detection head 42 from the oil filling port. When detecting the airtightness of the oil filling port, the telescopic end of the third telescopic member 41 is extended, and the airtight detection head 42 is inserted into the oil filling port, pressurized to above 0.3MP for 20s and detect the leakage rate. The test results can be recorded by relevant programs to ensure that the test process is not missed and can be traced later; when the test is completed, the telescopic end of the third telescopic member 41 is retracted, and the airtight detection head 42 is pulled out from the oil filling port to prevent the airtight detection head 42 from colliding with the automobile cross beam and torsion beam when the airtight detection mechanism 4 and the oil filling mechanism 5 are switched.

[0029] like Figure 2 As shown, the oil filling mechanism 5 includes a fourth telescopic member 51 and an oil filling head 52, the oil filling head 52 is installed at the telescopic end of the fourth telescopic member 51, and the fourth telescopic member 51 is installed on the mounting plate 324 along the Z direction. After completing the airtightness detection process, the Y direction of the moving mechanism 3 moves the moving mechanism so that the oil filling mechanism 5 is aligned with the oil filling port, and then the telescopic end of the fourth telescopic member 51 is extended, and the oil filling head 52 is inserted into the oil filling port to fill the oil. A flow meter is also provided on the oil filling head 52, and the flow meter ensures that 200 ml of oil is filled, while ensuring the efficacy of the anti-wear oil and preventing the anti-wear oil from being wasted or leaking out of the oil. The flow meter can be connected to an external computer for recording to ensure that the filling process is not missed and can be traced later.

[0030] Example 2

[0031] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, the clamping assembly 2 includes a positioning frame 21 and a positioning fixture 22, wherein the positioning frame 21 is mounted on the base plate 1, and the positioning fixture 22 is mounted on the base plate 1. The positioning frame 21 and the positioning fixture 22 clamp the automobile torsion beam and the cross beam from the upper and lower sides to ensure that the automobile torsion beam and the cross beam are always in a suitable position and will not move during the two processes of air tightness detection and oil filling.

[0032] like Figure 1As shown, the positioning fixture 22 includes a fifth telescopic member 221 and a clamping plate 222. The fifth telescopic member 221 is installed on the bottom plate 1. The clamping plate 222 is connected to the telescopic end of the fifth telescopic member 221. The fifth telescopic member 221 can drive the clamping plate 222 to clamp or loosen the automobile cross beam and the torsion beam. When the telescopic end of the fifth telescopic member 221 is extended, the clamping plate 222 can be driven to clamp the automobile torsion beam and the cross beam. When the telescopic end of the fifth telescopic member 221 is retracted, the clamping plate 222 can be driven to release the automobile torsion beam and the cross beam, so that the automobile torsion beam and the cross beam can be taken and replaced.

[0033] Example 3

[0034] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, the base plate 1 is provided with a first mounting surface 11 and a second mounting surface 12, and the first mounting surface 11 and the second mounting surface 12 are arranged in parallel and back to back. The clamping assembly 2 is installed on the first mounting surface 11, and the moving mechanism 3 is installed on the second mounting surface 12. The base plate 1 is provided with a hollow structure for the airtightness detection mechanism 4 and the oil filling mechanism 5 to extend into the part close to the oil filling port of the automobile cross beam and the torsion beam. Since there are many parts in the airtightness measurement and oil filling tooling, installing all parts on a single mounting surface will lead to a complex structure, and different parts may interfere with each other during the installation process, which puts forward higher requirements for the layout design of each part. By setting the two opposite surfaces of the base plate 1 as the first mounting surface 11 and the second mounting surface 12, the parts that were originally arranged on only one mounting surface can be arranged on two three-dimensional mounting surfaces, and the original two-dimensional arrangement is upgraded to a three-dimensional arrangement, providing a larger arrangement space for the parts arrangement, making the arrangement more scientific and reasonable. In the two processes of air tightness detection and oil filling, the parts of the air tightness detection and oil filling tooling are mainly divided into two categories, one is the parts that remain static, including the clamping assembly 2 and the automobile torsion beam and cross beam, and the other is the parts that need to move, including the moving mechanism 3, the air tightness detection mechanism 4 and the oil filling mechanism 5. The parts that remain static are integrated and installed on the first mounting surface 11, and the parts that need to move are integrated and installed on the second mounting surface 12 to ensure that the parts that need to move will not be disturbed by the static parts during the movement. The air tightness detection mechanism 4 and the oil filling mechanism 5 need to be inserted into the oil filling port of the automobile torsion beam and cross beam to work. The air tightness detection mechanism 4 and the oil filling mechanism 5 need to be extended from the second mounting surface 12 into the first mounting surface. Therefore, the bottom plate 1 is a hollow structure at the part close to the oil filling port of the automobile cross beam and torsion beam to leave space for the air tightness detection mechanism 4 and the oil filling mechanism 5 to be inserted.

[0035] like Figure 1As shown, the two ends of the base plate 1 are also provided with connecting members 6, which are connected to the flipping mechanism to drive the air tightness test and oil filling tooling to flip. The flipping mechanism includes a bracket, a motor and a connecting plate. The motor is installed on the bracket, located at the two ends of the base 1, and is erected in the air by the bracket to prevent the base 1 from colliding with other structures due to lack of space during flipping. The connecting plate is fixed on the output shaft of the motor, and the connecting member 6 is fixed on the connecting plate. When the motor is started, the output shaft of the motor rotates to drive the connecting plate to rotate, and the connecting member 6 is fixed on the connecting plate. The connection plate rotates to drive the connecting member 6 to rotate and then drive the chassis 1 to rotate. When placing and removing the automobile torsion beam and cross beam, the main operation is on the first mounting surface 11. When performing the two processes of air tightness detection and oil filling, the main operation is on the second mounting surface 12. When the worker is operating, it is more convenient to operate the mounting surface facing upward. Therefore, when placing and removing the automobile torsion beam and cross beam, the flipping mechanism is started so that the first mounting surface 11 faces upward. When the airtightness test and oil filling processes are performed, the flipping mechanism is activated so that the second mounting surface 12 faces upward.

[0036] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
