Description

Technical Field

[0001] This utility model relates to the field of automotive engine bracket testing technology, specifically a testing structure for automotive engine brackets. Background Technology

[0002] The engine mount is a key component of the car engine system. Its main function is to fix the engine to the frame and to absorb shock, preventing engine vibration from being transmitted into the vehicle.

[0003] When car engine mounts leave the factory, their dimensions, hole spacing, and hole positions need to be inspected. The existing inspection method is to use vernier calipers. However, since the position of the mount cannot be fixed, the inspection cannot be controlled, which reduces the reliability of the inspection results.

[0004] An existing authorized patent describes a detection structure for an automotive engine mount, patent number CN202022163713.3. It places the engine mount on a base, activates an electric push rod to move a movable plate to the right, and clamps and fixes the engine mount between the movable plate and the fixed plate, thereby achieving a stable effect when the device detects the engine mount.

[0005] When inspecting an automotive engine mount, the aforementioned utility model requires the use of electronic plug gauges, positioning rods, and laser emitters to inspect its dimensions, hole positions, and shape. During inspection, the automotive engine mount needs to be moved to a specific position according to different inspection requirements, which is cumbersome and affects inspection efficiency.

[0006] Therefore, we have made improvements to this and proposed a detection structure for an automotive engine mount. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This utility model discloses a testing structure for an automotive engine bracket, comprising a testing platform.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1 to 3 As shown, the present invention discloses a testing structure for an automobile engine bracket, including a testing platform 1. A magnetic levitation ring rail 2 is fixedly installed on the top surface of the testing platform 1. A slider 4 is slidably arranged on the magnetic levitation ring rail 2, and a laser emitter 5 is fixedly arranged on the slider 4. The laser emitter 5 can move on the magnetic levitation ring rail 2 through the slider 4.

[0023] A cavity 11 is provided on one side of the testing platform 1. Two electric push rods 10 and one electric push rod 18 are fixedly installed in the cavity 11. A connecting plate 7 is fixedly installed at the telescopic end of the electric push rod 10. A connecting block 9 is fixedly connected to the top surface of the connecting plate 7. A top plate 8 is fixedly connected to the top surface of the connecting block 9. A telescopic rod 17 is hinged to the side of the connecting block 9. The height of the connecting plate 7, the connecting block 9 and the top plate 8 can be adjusted by the electric push rod 10, so as to facilitate the limiting of the car engine bracket by the telescopic rod 17. When the laser emitter 5 is being tested, the connecting plate 7, the connecting block 9 and the top plate 8 can be moved into the testing platform 1 to prevent interference with the laser emitter 5.

[0024] The telescopic end of the electric push rod 18 is fixedly connected to the mounting plate 12, and three positioning rods 6 are fixedly installed on the top surface of the mounting plate 12. The electric push rod 18 can drive the mounting plate 12 to move, thereby driving the positioning rods 6 to move. The height of the positioning rods 6 can be adjusted to facilitate the detection of the hole position on the car engine bracket. After the detection is completed, the electric push rod 18 will drive it to move into the testing table 1. A storage frame 3 is installed on one side of the testing table 1. An electronic plug gauge 14 is placed in the storage frame 3, and the size of the hole can be detected by hand using the electronic plug gauge 14.

[0025] The structure and working principle of the laser emitter 5 and the electronic plug gauge 14 are the same as those of the laser emitter and electronic plug gauge 14 described in the prior art. They will not be described in detail here. The laser emitter 5 moves on the magnetic levitation ring rail 2 via the slider 4 to detect whether the shape structure of the car engine bracket meets the requirements. The laser emitter 5 is used in conjunction with the existing light guide plate (not shown in the figure). Its detection results can be displayed on the light guide plate. If the light cannot be displayed on the light guide plate, it means that the shape dimension detection is not up to standard. The electronic plug gauge 14 is used to detect the aperture size.

[0026] The top surface of the testing platform 1 has two symmetrically formed square slots that communicate with the cavity 11, and the dimensions of the square slots match those of the top plate 8 and the connecting plate 7. The top surface of the testing platform 1 also has three circular slots that communicate with the cavity 11, and these circular slots correspond to the positions of the positioning rods 6, and are matched with the positioning rods 6. When scanning is required by the laser emitter 5, the top plate 8 needs to be moved until its top surface is flush with the square slots, and the top surface of the positioning rods 6 is flush with the top surface of the circular slots.

[0027] Mounting seats 16 are symmetrically installed on opposite surfaces of the connecting block 9. One end of the telescopic rod 17 is hinged to the mounting seat 16. The telescopic rod 17 consists of a fixed end and a telescopic end. The telescopic end is slidably sleeved on the surface of the fixed end, and the telescopic end and the fixed end are limited by fastening bolts. A rubber pad is sleeved on the end of the telescopic end. Fixing holes that mate with the fastening bolts are opened on the telescopic end and the fixed end, and the position of the telescopic end on the fixed end can be adjusted as needed. In use, the telescopic rod 17 is moved so that its end faces the car engine bracket. A limiting plate (not shown in the figure) that fits against the surface of the car engine bracket can be placed on the telescopic rod 17 and the car engine bracket. The telescopic end 17 presses against the limiting plate and fits against the car engine bracket. When not in use, the limiting plate can be placed in the storage box 3.

[0028] The front of the testing platform 1 is detachably equipped with a baffle 13 for sealing the cavity 11 opening. The top surface of the storage frame 3 is open, and a sliding groove 15 is provided on one side of the top surface of the storage frame 3. A sliding plate is slidably mounted on the top surface of the storage frame 3. A square block is provided at the bottom of the sliding plate and slidably connected to the sliding groove 15. The sliding plate is slidably mounted in the sliding groove 15 through the square plate, which can play a guiding role when the sliding plate is moved.

[0029] During operation, the position of the holes in the car engine bracket can be detected first. After the detection is completed, the positioning rod 6 is moved down by the electric push rod 18, and the connecting plate 7 is moved up by the electric push rod 10, which facilitates the positioning of the car engine bracket. After positioning, the hole diameter is detected by the electronic plug gauge 14. After the detection is completed, the electric push rod 10 moves the connecting plate 7 down, and the car engine bracket is scanned by the laser emitter 5. During the operation, it is not necessary to frequently move the car engine bracket, which improves the detection efficiency.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
