Description

Technical Field

[0001] The utility model discloses a novel practical conveying roller for conveying workpieces of a cleaning machine, and relates to the technical field of conveying devices, in particular to a workpiece conveying mechanism of a car engine cleaning machine, and in particular to a pallet conveying mechanism and a workpiece conveying mechanism in a humid and corrosive environment. Background Art

[0002] The degree of automation on the production line of engine assembly is getting higher and higher. Roller conveyor is particularly common, but the cost of machined rollers is high, the processing and assembly time is long, and the maintenance is complicated. Ordinary stamping rollers have the limitations of low precision and small conveying load.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new practical conveying roller for conveying workpieces of a cleaning machine, so as to overcome the problems existing in the prior art. Summary of the invention

[0004] According to the machined rollers proposed in the above-mentioned prior art, the processing materials are expensive, the processing technology is complicated, the wastewater and waste after the surface treatment required for corrosion prevention pollute the environment, the assembly is troublesome and laborious, and the maintenance and replacement of a single roller requires the disassembly and assembly of the entire roller, which consumes a lot of manpower, material resources and time, greatly affecting production efficiency. Although the existing ordinary stamping rollers shorten the processing, assembly and maintenance time, due to their low processing and assembly accuracy, they can only be used in conveying occasions with low precision requirements, and the conveying load is small. Their limitations cause technical problems such as low practicality in the field of engine assembly and cleaning, and provide a new practical conveying roller for conveying workpieces of cleaning machines. The utility model mainly utilizes the cooperation of the positioning screws with the stoppers on the two end faces of the core shaft and the inner hole of the roller beam to improve the assembly accuracy, increase the force-bearing area, and thus enhance the strength of the roller.

[0005] The technical means adopted by the utility model are as follows:

[0006] A new practical conveyor roller for conveying workpieces of a cleaning machine comprises a conveyor roller, both ends of which are mounted on a roller beam; two adjacent conveyor rollers are connected by a chain; a driving wheel mounted on a reducer is connected to the conveyor roller through one of the chains, and drives the conveyor roller to rotate to convey goods;

[0007] Further, the conveying roller comprises: a core shaft, a roller, a sprocket, a bearing and an end cap;

[0008] Further, each end of the mandrel is equipped with a bearing;

[0009] Furthermore, the inner hole and outer circle are directly processed on the sprocket, and fixedly assembled with the outer ring of the bearing at one end of the mandrel;

[0010] Furthermore, the end cover is directly punched with an inner hole and a reverse edge, and fixedly assembled with the outer ring of the bearing at the other end of the core shaft;

[0011] Furthermore, the roller is installed on the outside of the mandrel, one end of the roller is welded and assembled with the sprocket, and the other end of the roller is welded and assembled with the end cover;

[0012] Further, the sprockets on two adjacent conveying rollers are connected by a chain;

[0013] Furthermore, both ends of the conveying roller are assembled on the roller beam by means of positioning screws.

[0014] Furthermore, a stopper and an internal threaded hole used in conjunction with the outer diameter of the positioning screw are respectively processed on both end surfaces of the core shaft.

[0015] Furthermore, the outer diameter of the positioning screw matches the assembly through hole on the roller beam, which ensures the conveying accuracy while greatly improving the roller strength and increasing the conveying load.

[0016] Furthermore, the bearing is encapsulated inside the roller through the sprocket and the end cover and is not easily corroded.

[0017] The action process of the utility model is:

[0018] Each conveyor roller is assembled on the roller beams on both sides with two positioning screws, and every two adjacent conveyor rollers are connected with a chain, and two conveyor rollers are connected to the driving sprocket with a chain, and the driving sprocket is driven to rotate by the reduction motor. The chain drives the conveyor rollers of the entire roller to rotate, so as to achieve the purpose of conveying workpieces.

[0019] The stoppers at both end faces of the conveyor roller are installed on the rollers on both sides at the same height on the roller beam by means of positioning screws. The height tolerance of the inner hole of the roller beam, the verticality of the center line of the inner hole and the inner wall of the roller beam, the concentricity of the stopper on the end face of the mandrel and the center line of the threaded hole with the outer diameter of the mandrel, and the verticality of the end face of the mandrel ensure that each roller is at the same height, thereby ensuring that the working generatrix of each roller is in the same plane.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] 1. The utility model provides a new practical conveying roller for conveying workpieces of a cleaning machine, which has a large load-bearing capacity, is light in weight, is easy to install and disassemble, and has a wide range of applications;

[0022] 2. The new practical conveying roller for conveying workpieces of the cleaning machine provided by the utility model has high precision, corrosion resistance, small size, smooth movement, high long-term working stability, and good maintenance and replacement interchangeability;

[0023] 3. The new practical conveying roller for conveying workpieces of the cleaning machine provided by the utility model has simple processing technology, short processing time, few processing parts, simple assembly, high assembly accuracy, short debugging time and stable structure;

[0024] 4. The utility model provides a new practical conveying roller for conveying workpieces of a cleaning machine, which solves the problem of difficulty in replacing and disassembling the roller in a humid and narrow environment and long downtime.

[0025] In summary, the technical solution of the utility model solves the problems in the prior art of high cost, long processing and assembly time, and complex maintenance of machined rollers; low precision of stamping rollers, small conveying load, and easy damage.
