Description

Engine assembly line ground chain conveyer belt stop block structure

Technical Field

The utility model relates to the technical field of engine assembly equipment, in particular to a stop block structure of a ground chain conveyor belt of an engine assembly line.

Background

The engine assembly ground chain conveyor brakes the engine carrying tray by means of the stop for operation. Since the layout limiting part has 1 stopper to stop a plurality of trays, the following disadvantages are caused: 1. the load is large: the tray of dog braking is in large quantity, therefore whole quality is big, simultaneously because the dog is the design of cut-in, so braking time is short, so to sum up the momentum of whole impact huge. 2. The action is frequent: the transmission beat of the conveyor belt is 54s, and the production requirement is increased to 50s after 18 years and 5 months. By combining the two points, the repeated impact of large load is about 1226 times per day, and the weak link of the stop block connection is easy to cause metal fatigue to cause fracture.

SUMMERY OF THE UTILITY MODEL

In order to effectively solve the problems in the background technology, the utility model provides a stop block structure of a ground chain conveyor belt of an engine assembly line, and the specific technical scheme is as follows;

the utility model provides an engine assembly line ground chain conveyer belt dog structure which characterized in that: the device comprises a bearing bracket, a left guide block, a right guide block, a wheel support block, a roller, a lifting plate and a transmission shaft; the left guide block and the right guide block are fixed on one side of the bearing support respectively, a sliding groove is formed in one side, corresponding to the left guide block and the right guide block, of the lifting plate, the two sides of the lifting plate are arranged in the sliding groove and are in sliding fit with the sliding groove, the upper portion of the lifting plate is fixedly connected with the wheel supporting block, the idler wheel is installed on the upper portion of the wheel supporting block through a rotating shaft, an oval hole is formed in the lifting plate, a cam and a brake block are arranged at the front end of the transmission shaft, the cam is matched with the oval hole, and the brake block is matched with a stop block fixed on one side of the right guide block.

Preferably, the drive shaft passes through the bearing bracket and is connected with an internal bearing.

Preferably, an adjusting groove is formed in the lifting plate in the vertical direction, and the wheel supporting block is fixed with the adjusting groove through an adjusting bolt.

Preferably, the upper part of the lifting plate is provided with a U-shaped opening, and the two sides of the wheel supporting block are provided with clamping grooves which are connected with the side wall of the U-shaped opening.

Compared with the prior art, the utility model has the beneficial effects that: the device drives the lifting plate to lift up and down by changing the end part of the transmission shaft into the structure of the cam, and is applied to the conveyor belt braking stop block with higher load, so that the reliability of the stop block mechanism is improved.

Detailed Description

The following detailed description of the preferred embodiments will be made with reference to the accompanying drawings. As shown in fig. 1-3, a stop block structure of a ground chain conveyor belt of an engine assembly line comprises a bearing bracket 1, a left guide block 2, a right guide block 3, a wheel support block 4, a roller 5, a lifting plate 6 and a transmission shaft 7; the left guide block and the right guide block are respectively fixed on one side of the bearing support, sliding grooves 8 are respectively formed in one corresponding side of the left guide block and the right guide block, two sides of the lifting plate are arranged in the sliding grooves and are in sliding fit with the sliding grooves, the upper portion of the lifting plate is fixedly connected with the wheel support block, as shown in fig. 4, an adjusting groove 13 is formed in the lifting plate in the vertical direction, and the wheel support block is fixed with the adjusting groove through an adjusting bolt. The upper part of the lifting plate is provided with a U-shaped opening 14, the two sides of the wheel supporting block are provided with clamping grooves 15 which are connected with the side wall of the U-shaped opening, and the roller is arranged on the upper part of the wheel supporting block through a rotating shaft. Have elliptical hole 9 on the lifter plate, the front end of transmission shaft is provided with cam 10 and brake pads 11, the cam with elliptical hole cooperation, cam rotation drive elliptical hole rotate to drive the lift about the lifter plate, drive the gyro wheel and reciprocate and shelter from, for making the lifter plate have extreme position, the brake pads cooperates with the dog 12 of fixing on one side of the right guide block, and after the brake pads contacted the dog, the lifter plate rose to the highest, for the position of limit, the gyro wheel was in and shelters from the state. In order to make the rotation of the transmission shaft more smooth, the transmission shaft passes through the bearing bracket and is connected with an inner bearing.

This device sets up the cam structure with the transmission shaft to the utensil resists horizontal force and the intensity of vertical force, or eliminates the atress of connecting portion. The transmission mode is changed, and the cam piece is removed, so that no connecting diameter of 6mm exists.
