Description

Technical Field

[0001] This utility model relates to the field of chassis workstation transfer technology, and in particular to a workstation transfer device for chassis welding. Background Technology

[0002] Currently, after the chassis is welded, it needs to be transferred via conveyor belt. During the transfer, it is transported to the transfer position via a conveyor belt on one side, and then transferred to a conveyor belt facing the opposite direction by steering, thus achieving a change in the conveying direction. However, traditional transfer devices use a fixed steering structure, which leads to: 1. Flexibility deficiency: The direction of frame conveying is limited by a preset angle, which cannot adapt to the needs of mixed production lines for multiple models; 2. Secondary positioning cost: requires manual intervention or the addition of transfer equipment, increasing production cycle time by 15%-20%.

[0003] To address this issue, we propose a station transfer device for chassis welding. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-4A workstation transfer device for vehicle frame welding includes a support seat 101, a fixed seat 102 connected to one side of the support seat 101, the support seat 101 and the fixed seat 102 are welded from high-strength steel and are hollow inside to reduce weight. A support shaft 403 is rotatably connected to the bottom of the support base 101, and a turntable 301 is installed on the upper end of the support shaft 403; A first servo motor 201 is installed on one side of the upper end of the fixed base 102. A sprocket 204 is fixedly mounted on both the output shaft and the support shaft 403 of the first servo motor 201. A chain 202 meshes between the two sprockets 204. Three mounting plates 302 are fixed at equal intervals on the upper end of the turntable 301. Support wheels 304 are rotatably connected to both sides of the upper end of the mounting plates 302. A second servo motor 303 is mounted on one side of the upper end of the mounting plate 302. One end of the second servo motor 303 is connected to one side of one of the support wheels 304. The surface of the support wheel 304 is covered with a polyurethane coating to provide high friction to prevent the frame from sliding and reduce noise. A mounting bracket 501 is fixed to one side of the bottom inside the support 101. An angle sensor 502 is installed on one side of the upper end of the mounting bracket 501. A sensing block 503 is fixedly mounted on the support shaft 403. The sensing block 503 corresponds to the angle sensor 502. The sensing block 503 is made of magnetic material. The angle sensor 502 can capture minute angle changes of 0.1° in real time and transmit data to the control system through the CAN bus to form a high-response closed loop. The upper end of the support shaft 403 passes through the side wall of the bearing seat 101 and extends to the upper end of the bearing seat 101. A connecting plate 401 is fixed to the upper end of the support shaft 403. The connecting plate 401 is connected to the lower end of the turntable 301 by multiple screws 402. The screws 402 are M12 high-strength bolts. The pre-tightening force design eliminates the connection gap and improves the overall rigidity. A tension wheel 203 is rotatably connected to one side of the bottom of the bearing seat 101. The tension wheel 203 meshes with one side of the chain 202. The sprocket 204 is made of wear-resistant alloy material to ensure a transmission efficiency of over 95%. Multiple pads 103 are fixed at equal intervals at the lower ends of the bearing seat 101 and the fixed seat 102. The multiple pads 103 can level the ground and adapt to uneven workshop environments. The rubber damping layer of the pads 103 can absorb vibration and improve the life of the device. One end of the carrier 101 and the fixed base 102 are connected to each other, which facilitates centralized cable management and reduces the risk of external interference.

[0016] In this utility model, when transferring the chassis: Phase 1: Chassis Receiving and Positioning The upstream conveyor belt transports the vehicle frame to the surface of turntable 301, and the angle sensor 502 and control system monitor the initial angle of the support shaft 403 in real time. Phase 2: Dynamic Angle Adjustment (1) Issuance of instructions The control system calculates the required rotation angle, for example, 60°, based on the coordinates of the target workstation. (2) Precision rotary drive The first servo motor 201 drives the support shaft (403) to rotate to the corresponding angle through the sprocket 204 and the chain 202. The tension wheel 203 compensates for the chain tension and eliminates the transmission gap. The angle sensor 502 and the sensing block 503 form a closed-loop feedback to correct the angle deviation to within ±0.5° in real time. (3) Structural reinforcement The support shaft 403 rigidly fixes the turntable 301 through the connecting plate 401 and screws 402, increasing the torsional strength by 40%. Phase 3: Targeted Output Once the turntable is in position, the second servo motor 303 starts, and the support wheel 304 rotates synchronously, sliding the frame into the downstream conveyor belt at a set angle.

[0017] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
