Description

Technical Field

[0001] The present invention relates to the field of automobile manufacturing, and in particular to an automobile hood lock installation and positioning device. Background Art

[0002] The clearance and flushness of a car's hood refers to the gap between the hood and surrounding components (such as the vehicle body, headlights, and fenders). This gap must meet design standards to ensure the vehicle's overall appearance and functional performance. Excessively large or small gaps can affect the vehicle's aesthetics, airtightness, and overall performance. Too small a gap can cause friction damage, while too large a gap can affect aerodynamic performance and sealing. Newly developed models have stricter requirements for the clearance and flushness between the hood and surrounding parts.

[0003] However, the installation of the hood lock affects the clearance and flushness between the hood and surrounding parts. Installing the hood lock without dedicated positioning tooling can result in poor clearance and flushness between the hood and surrounding parts after assembly, frequently requiring repairs. This is not only time-consuming and labor-intensive, but can also easily damage the paint finish. Summary of the Invention

[0004] In view of the defects in the prior art, the purpose of the present invention is to provide a vehicle hood lock installation and positioning device, which can increase the positioning accuracy of the vehicle hood lock and improve the installation efficiency.

[0005] In order to achieve the above technical effects, the present invention adopts the following technical solutions:

[0006] The present invention provides a vehicle hood lock installation and positioning device, comprising: a first vehicle body positioning pin, a second vehicle body positioning pin, a hood lock body positioning pin, a hood lock body pressing and positioning arm, a transfer block, a rotating mechanism, and a tooling beam;

[0007] The first body positioning pin and the second body positioning pin are respectively located at both ends of the tooling crossbeam, and a pin body is provided at the lower part. The pin body can be inserted into the hole on the body crossbeam to play a positioning role;

[0008] The adapter block is fixed to the middle of the tooling crossbeam, and the lower part is connected to the hood lock body positioning pin, and the hood lock body positioning pin is used to clamp the hood lock body;

[0009] The rotating mechanism is connected to the tooling beam, and the hood lock body pressing and positioning arm is connected to the rotating mechanism. Through the rotation of the rotating mechanism, the hood lock body pressing and positioning arm can be moved toward the tooling beam to press the hood lock body.

[0010] Preferably, it further comprises a first vehicle body positioning block and a second vehicle body positioning block, which are fixed on the tooling crossbeam and are adjacent to the first vehicle body positioning pin and the second vehicle body positioning pin respectively, and are used for limiting the position in the direction of the pin body.

[0011] Preferably, a handle is further provided on the top of the tooling crossbeam for lifting and placing the automobile hood lock installation and positioning device.

[0012] Preferably, guide blocks are installed on both sides of the first vehicle body positioning block and the second vehicle body positioning block to enhance stability.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention accurately installs the lock body at the designed position of the vehicle body by positioning the lock body and the vehicle body. Failure to use positioning tooling results in a deviation between the installation of the lock body and the designed position, and an excessive gap between the hood and surrounding parts after the hood is closed. The present invention ensures the gap between the hood and surrounding parts.

[0015] 2. When the present invention is positioned on the vehicle body, it can be kept stably positioned on the vehicle body without the help of human hands, so that one person can complete the entire process of positioning and tightening the hood lock body, thereby improving work efficiency.

Specific embodiments

[0037] The technical solutions of the present invention are described in detail below through examples. The following examples are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and are not to be construed as limiting the technical solutions of the present invention.

[0038] like Figure 1As shown, this embodiment provides a car hood lock installation and positioning device, including: a first body positioning pin 101, a second body positioning pin 102, a first body positioning block 201, a second body positioning block 202, a hood lock body positioning pin 3, a hood lock body clamping positioning arm 4, an adapter block 5, a guide block 601, a rotating mechanism 7, a tooling beam 8, and a handle 9.

[0039] Among them, the first body positioning pin 101 and the second body positioning pin 102 are respectively located at the two ends of the tooling beam 8, with a pin body at the lower part. The shape of the pin body matches the hole position on the actual body beam, and plays a positioning role after insertion.

[0040] The first body positioning block 201 and the second body positioning block 202 are adjacent to the first body positioning pin 101 and the second body positioning pin 102 respectively, and are fixed to the lower side of the tooling beam 8 to limit the position in the vertical direction when the device provided in this embodiment is used.

[0041] Guide blocks 601 are installed on both sides of the first vehicle body positioning block 201 and the second vehicle body positioning block 202 to make the connection between the device and the actual vehicle body cross beam more stable.

[0042] The adapter block 5 is fixed to the middle of the tooling beam 8, and the lower part is connected to the hood lock body positioning pin 3. When the device provided by this embodiment is used, it plays a role of limiting the lock body in the vertical direction.

[0043] The handle 9 is located on the top of the tooling beam 8, which is convenient for the operator to pick up and place the device provided by this embodiment.

[0044] The hood lock body locating pin 3 is connected to the adapter block 5 and is used to lock the hood lock body. The rotating mechanism 7 is connected to the tooling crossbeam 8, and the hood lock body pressing and positioning arm 4 is connected to the rotating mechanism 7. The rotating mechanism 7 is rotatable, and when the handle on the top of the rotating mechanism 7 is pressed down, the rotating mechanism 7 rotates, causing the hood lock body pressing and positioning arm 4 to move toward the tooling crossbeam 8. When the handle on the top of the rotating mechanism 7 is lifted, the rotating mechanism 7 rotates and opens the hood lock body pressing and positioning arm 4, making it easier to insert the lock body and position it.

[0045] The following describes in detail the method for using the automobile hood lock installation and positioning device provided in this embodiment. Figure 2As shown. When using the positioning device provided in this embodiment for positioning, first hold the handle 9 and lift the tooling to the vehicle body cross beam 11, and insert the first vehicle body positioning pin 101 and the second vehicle body positioning pin 102 from top to bottom into the square holes on the vehicle body cross beam 11 until the first vehicle body positioning block 201 and the second vehicle body positioning block 202 contact the upper surface of the vehicle body cross beam 11, and the positioning of the tooling and the vehicle body is completed. Then, turn the handle of the rotating mechanism 7 to rotate and open the hood lock body pressing and positioning arm 4, take the hood lock body 10 and align its groove with the hood lock body positioning pin 3 to snap it in, turn the handle of the rotating mechanism 7 to rotate and press the hood lock body pressing and positioning arm 4 downward, and the lower part of the hood lock body pressing and positioning arm 4 pushes the hood lock body 10 upward until it contacts the hood lock body positioning pin 3 and the adapter block 5, completing the positioning of the hood lock body 10. Finally, tighten it using a tightening tool.

[0046] The automobile hood lock positioning mechanism of the present invention accurately positions the hood lock on the vehicle body, ensuring the required clearance between the hood and surrounding parts. Furthermore, the first and second body locating pins 101, 102, and the first and second body locating blocks 201, 202 are used to position the tooling and the vehicle body crossbeam 11. This eliminates the need for manual stabilization, freeing workers to tighten the hood lock, enabling single-person positioning and assembly of the hood lock.

[0047] The above describes the specific embodiments of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the scope of the technical concept of this invention.
