Description

Technical Field

[0001] The invention relates to a chip conveyor rear shaft and belongs to the technical field of machine tool waste chip conveying. Background Art

[0002] The chip conveyor is mainly used to collect various metal or non-metal waste chips generated by machine tools and transport the waste chips to the chip collection box. The transmission of the existing chip conveyor is mainly through a conveyor chain, which is wrapped around the front drive shaft and the rear shaft of the chip conveyor. The front drive shaft is provided with a transmission sprocket that cooperates with the conveyor chain, and the rear shaft of the chip conveyor is installed on the rear side of the chip conveyor housing.

[0003] The support part of the existing chip conveyor rear axle is mostly an integrated part made of round steel bars, and a guide wheel for supporting the conveyor chain is fixedly installed on the support part. The guide wheel mainly supports the chain roller part of the chain so that the chain roller runs on the guide wheel, and the end of the integrated part is a flat structure. The mounting shells at both ends of the shaft are respectively provided with mounting holes that match the ends of the integrated part, and the two ends of the integrated part are respectively installed on the mounting holes of the shells on both sides. When the chip conveyor is used in a wet processing environment and does not have an additional water tank, after the chip conveyor rear axle is installed, the chip conveyor shell needs to be fully welded to prevent leakage of the shell. In this case, after the conventional rear axle is installed, the space of the rear axle part is very tight. When maintenance is required in the future, the rear axle is difficult to remove and often requires destructive dismantling.

[0004] Since the chain roller of the conveyor chain runs on the guide wheel of the chip conveyor rear shaft, the guide wheel will wear out after long-term use. Or during the production process, iron chips accumulate on the rear shaft end, causing the chain to get stuck, and the rear shaft needs to be replaced or disassembled. When replacing, the integrated part needs to be removed, and then the worn guide wheel is removed and replaced with a new one, and then the chip conveyor rear shaft is installed on the chip conveyor housing. From the perspective of the disassembly and assembly of the chip conveyor rear shaft, each disassembly and assembly requires the integrated part to be removed before the guide wheel can be replaced, resulting in a cumbersome disassembly and assembly process, and low efficiency in the installation and disassembly process of the chip conveyor rear shaft, which affects the operating efficiency of the chip conveyor.

[0005] In addition, after the chip conveyor rear shaft is installed, the shell needs to be sealed. When disassembling the chip conveyor rear shaft, it is necessary to first disassemble the mounting parts used to seal the shell, and then the chip conveyor rear shaft can be disassembled. After the guide wheel of the chip conveyor rear shaft is replaced and installed, the shell needs to be sealed again, which affects the disassembly and assembly efficiency of the chip conveyor rear shaft and seriously affects the production efficiency of the chip conveyor.

[0006] In addition, after the chip conveyor rear shaft is installed and the shell is sealed, due to the limited space in the chip conveyor shell, the sealed shell often becomes a non-removable structure, making the installation and disassembly of the chip conveyor rear shaft even more difficult.

[0007] Therefore, there is an urgent need for a chip conveyor rear axle with a simple structure, easy replacement when worn, low replacement cost, no restrictions on installation space, easy and quick installation and disassembly, and improved chip conveyor production efficiency. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a chip conveyor rear axle with a simple structure, low guide wheel wear and maintenance cost, and the guide wheel can be disassembled and assembled in a limited space. The guide wheel can be disassembled and assembled conveniently and quickly, thereby improving the production efficiency of the chip conveyor.

[0009] The technical solution of the present invention for solving the above-mentioned technical problems is as follows: a rear shaft of a chip conveyor, comprising a support shaft and guide wheel assemblies respectively arranged at both ends of the support shaft, the guide wheel assembly comprising a guide wheel and a fixed seat, the fixed seat is installed on the chip conveyor housing, the guide wheel is arranged between the fixed seat and the support shaft, a positioning boss for positioning the guide wheel is provided on the inner end surface of the fixed seat, a positioning groove for engaging with the positioning boss is provided on the outer end surface of the guide wheel, a mounting hole is provided on the guide wheel, a mounting window for connecting the support shaft with the guide wheel assembly is provided on the support shaft, and the support shaft is connected to the fixed seat.

[0010] The beneficial effects of the present invention are as follows: the traditional one-piece rear axle structure inserted into the shaft hole is changed into a segmented detachable structure, and the installation method of the rear axle assembly and the chip conveyor housing is changed. During installation, the fixed seat is first fixedly installed on the inner wall of the chip conveyor housing, and then the guide wheel is engaged with the fixed seat through the cooperation of the positioning groove and the positioning boss, and then the support shaft is installed between the guide wheel assembly, and the end of the support shaft is connected to the fixed seat. The guide wheel is used to carry the conveying chain. The guide wheel is worn after long-term use. The support shaft can be removed in the limited rear axle installation space, and then the guide wheel is removed and replaced with a new guide wheel and installed on the fixed seat. The guide wheel can be disassembled and assembled in the limited space of the chip conveyor housing, and the disassembly and assembly are convenient and fast, which improves the installation and disassembly efficiency of the guide wheel. In short, the rear axle assembly of the present invention adopts a segmented detachable structure, which is simple in structure, easy to maintain, and has low maintenance cost. The installation and disassembly are not limited by space. The guide wheel can be installed and disassembled conveniently and quickly in the limited installation space, and it is easy to replace, which improves the disassembly and assembly efficiency of the rear axle of the chip conveyor, thereby improving the production efficiency of the chip conveyor.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, two positioning planes are arranged in parallel on the positioning boss, and two engaging bosses are arranged on the outer end surface of the guide wheel. The inner surface of the engaging boss is a planar structure matched with the positioning plane, and the positioning groove is formed between the two engaging bosses.

[0013] The beneficial effect of adopting the above further scheme is that the positioning boss is inserted into the positioning groove between the two engaging bosses, the planar structures of the two engaging bosses are in contact with the two corresponding positioning planes respectively, and the stable positioning of the guide wheel is achieved through the positioning boss of the fixed seat.

[0014] Furthermore, an annular boss is provided on the outer end surface of the guide wheel, and the engaging boss is arranged on the annular boss.

[0015] The beneficial effect of adopting the above further solution is that the design of the annular boss increases the distance between the engagement position of the guide wheel and the fixed seat and the guide wheel on the one hand to avoid affecting the transmission of the chain, and on the other hand to stably support the engagement boss.

[0016] Furthermore, the fixing seat is also provided with a mounting boss which is inserted and matched with the mounting hole of the guide wheel, and the mounting boss is arranged on the positioning boss.

[0017] The beneficial effect of adopting the above further scheme is that the mounting boss is inserted into the inside of the guide wheel, which can not only stably support the guide wheel, but also facilitate the connection between the end of the support shaft and the fixed seat, making the connection more stable.

[0018] Furthermore, the support shaft is connected to the mounting boss via bolts.

[0019] The beneficial effects of adopting the above further solution are that materials are easy to obtain and the cost is low, and assembly and disassembly are quick and convenient.

[0020] Furthermore, the outer diameter of the annular boss is smaller than the outer diameter of the guide wheel.

[0021] The beneficial effect of adopting the above further solution is that the chain roller of the chain runs on the outer circle of the guide wheel. If the outer diameter of the annular boss is equal to or greater than the outer diameter of the guide wheel, it will affect the transmission action of the conveyor chain.

[0022] Furthermore, the two sides of the two positioning planes are respectively connected by positioning arc surfaces, the outer surface of the engaging boss is the engaging arc surface, and the positioning arc surface cooperates with the engaging arc surface to form a circular structure.

[0023] The beneficial effect of adopting the above further scheme is that after the outer end surface of the guide wheel is engaged with the fixed seat, a cylindrical structure is formed. On the one hand, the position is easy to adjust when engaged and the outer surface is easy to clean and maintain; on the other hand, the appearance is beautiful and the engagement is convenient.

[0024] Furthermore, the outer diameter of the circular structure is consistent with the outer diameter of the annular boss.

[0025] The beneficial effect of adopting the above-mentioned further scheme is that the outer diameter of the engaging boss and the annular boss is the same, which is convenient for the processing of the boss on the one hand, and on the other hand, the guide wheel and the fixed seat form an outer circle structure with the same outer diameter after engaging with each other, which is not only convenient for engaging and beautiful in appearance, but also convenient for maintenance of the rear axle assembly.

[0026] Furthermore, the support shaft is a hollow shaft structure.
