Description

Technical Field

[0001] This utility model belongs to the technical field of positioning fixtures for vehicle frame painting, and specifically relates to a positioning fixture for elevated painting. Background Technology

[0002] The positioning fixture for overhead painting of vehicle frames is one of the most crucial pieces of equipment in the automotive manufacturing and repair industries. It is primarily used to precisely position the vehicle frame during the painting process to ensure the uniformity and accuracy of the paint application. The base of the positioning fixture is typically made of a robust material, such as steel, to ensure the fixture's stability and load-bearing capacity.

[0003] During the overhead painting process on the vehicle frame, workers first place the frame on a positioning fixture and secure it in place using clamping devices and a rotating disc. Then, the painting assembly begins operation, evenly spraying paint onto the frame. Throughout the process, the positioning fixture ensures the stability and accuracy of the frame, thereby improving the quality and efficiency of the painting process.

[0004] Existing positioning fixtures for spraying are extremely inconvenient during the positioning of tricycle frames due to the limitations of their structural design. The weight of the tricycle frame also increases the labor intensity of the operators during the fixing process, requiring them to spend more physical strength and time to cope with these challenges. This also directly leads to a significant decrease in work efficiency and a prolonged production cycle. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for overhead spraying, which aims to solve the problem that the positioning fixture is extremely inconvenient during the positioning of a tricycle frame due to the limitations of its structural design. The weight of the tricycle frame also increases the labor intensity of the operators during the fixing process, requiring them to spend more physical strength and time to cope with these challenges. In addition, it directly leads to a significant decrease in work efficiency and a prolonged production cycle.

A slide cylinder 12 is sleeved on the surface of the guide rod 11. A connecting plate 13 is connected between the slide cylinder 12 and the fixture base frame 1.

[0024] First, fix the tricycle frame on the surface of the positioning fixture. Then, the surface of the tricycle frame can be painted by the spraying mechanism. After the painting is completed, the tricycle frame is pushed away from the painting workshop by the casters at the bottom of the fixture base 1.

[0025] Preferably, the threaded tube 302 and the screw 303 are connected by a thread;

[0026] In practical use, the screw 303 can rotate inside the threaded tube 302 and move laterally. When the screw 303 drives the extrusion block 304 to move to the surface of the tricycle frame inside it, the position of the tricycle frame can be fixed.

[0027] Preferably, the positioning bracket 2 and the telescopic rod 10 form a lifting structure;

[0028] In actual use, the telescopic rod 10 can drive the positioning bracket 2 to rise and fall when it runs, so that the height of the positioning bracket 2 can be adjusted.

[0029] Preferably, the guide rod 11, the slide cylinder 12 and the connecting plate 13 are symmetrically arranged on both sides of the tooling base frame 1, and the slide cylinder 12 and the guide rod 11 are slidably connected;

[0030] In practical use, when the positioning bracket 2 is subjected to a force, it can drive the guide rod 11 to slide inside the slide cylinder 12, which can limit the movement direction of the positioning bracket 2.

[0031] Preferably, a bearing 4 is fitted onto the side surface of the positioning bracket 2, a rotating shaft 5 is connected through the inside of the bearing 4, one end of the rotating shaft 5 is connected to the clamping mechanism 3, the other end of the rotating shaft 5 is connected to the driven bevel gear 6, a drive motor 7 is mounted on the side surface of the positioning bracket 2, and the output end of the drive motor 7 is connected to the driving bevel gear 8.

[0032] Preferably, the rotating shaft 5 forms a rotating structure with the positioning bracket 2 via the bearing 4;

[0033] In practical use, when the rotating shaft 5 is subjected to a force, it can drive the clamping mechanism 3 to rotate inside the bearing 4.

[0034] Preferably, the driving bevel gear 8 and the driven bevel gear 6 form a meshing structure;

[0035] In practical use, when the drive motor 7 is running, it can drive the active bevel gear 8 to rotate.

The rotation of the driven bevel gear 6 can drive the rotating shaft 5 to rotate, thus realizing the transmission between the drive motor 7 and the rotating shaft 5.

[0036] The working principle of this utility model in specific use is as follows: When using this high-rise spraying positioning fixture, first insert the tricycle frame into the inner wall of the two limiting shells 9 on the same side. Then, the telescopic rod 10 can be operated. When the telescopic rod 10 is running, it can retract. When the telescopic rod 10 retracts, it can drive the positioning bracket 2 to move downward. When the positioning bracket 2 moves downward, it can drive the clamping mechanism 3 to move downward through the bearing 4 and the rotating shaft 5. When the clamping bracket 301 moves downward to the middle position of the tricycle frame, the screw 303 can be rotated. When the screw 303 rotates inside the threaded tube 302, it can move laterally. When the screw 303 drives the extrusion block 304 to the surface of the tricycle frame, the tricycle frame can be fixed. Then, when the telescopic rod 10 extends, it can drive the positioning bracket 2 to move upward. When the positioning bracket 2 moves upward, it can drive the clamping mechanism 3 to move upward through the bearing 4 and the rotating shaft 5.

[0037] Next, the tricycle frame can be sprayed using a spraying mechanism. After one side of the tricycle frame is sprayed, the drive motor 7 can be run. When the drive motor 7 is running, it can drive the active bevel gear 8 to rotate. The rotation of the active bevel gear 8 can drive the rotating shaft 5 to rotate through the driven bevel gear 6. When the rotating shaft 5 rotates, it can drive the tricycle frame to rotate through the clamping mechanism 3. After the tricycle frame rotates, the other side can be sprayed, thus facilitating multi-angle spraying.
