[0001] This utility model relates to the field of lawnmower parts processing technology, specifically a hollow shaft cutting device. Background Technology

[0002] Hollow shafts are mainly used for power transmission and blade connection in lawnmowers, and are an important component of lawnmowers. Hollow shafts can be directly connected to blades via bolts or keyways, and disassembly does not require disassembling complex parts. In the manufacturing process of hollow shafts for push-type fuel-powered lawnmowers, hollow steel pipes with a diameter of 40mm are required as raw materials. After the process documents are formulated, the raw materials are cut into blanks of specified lengths using a cutting device. Then, the outer circle and inner hole are ground to ensure accuracy, and surface treatments such as electroplating and anodizing are performed to enhance rust resistance and wear resistance.

[0003] Currently, the hollow shaft processing still requires operators to move the steel pipe under the cutting machine for cutting. During cutting, the steel pipe needs to be manually pressed to improve the cutting accuracy, which is somewhat dangerous and requires a lot of labor for the operators. Existing technology has not solved this problem. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 and Figure 3 This utility model provides a technical solution:

[0029] A hollow shaft cutting device includes a cutting assembly, which includes a cutting machine body 1. The cutting machine body 1 is fixedly installed on the bottom side of a lifting platform 3 via a mounting bracket 2. The top center of the lifting platform 3 is fixedly connected to the telescopic end of a hydraulic cylinder 4. The hydraulic cylinder 4 is fixedly installed at the top center of a top plate 10. The bottom periphery of the top plate 10 is fixedly connected to one side of the top surface of a processing table 12 via four sets of guide support rods 11. A passage groove is provided on one side of the lifting platform 3 to facilitate the rotation of the cutting machine saw blade. The four sets of guide support rods 11 slide around the lifting platform 3. The bottom of the processing table 12 is fixed. The control box is equipped with a control unit for controlling the main body 1 of the cutting machine, the hydraulic cylinder 4, and the motor 22. The control box uses a PLC as the control core, and is equipped with an HMI to realize logic processing and parameter setting. It also integrates a switching power supply to provide power for the machine, a circuit breaker to ensure circuit safety, a driver adapted to the type of motor 22, and a distance sensor. It uses relays to isolate high and low voltage circuits to control the conveying distance. It also includes components such as an electromagnetic reversing valve and a pressure sensor to control the hydraulic cylinder 4, and uses buttons, indicator lights, and sensors to realize signal input and status feedback.

[0030] By setting up a cutting component, the function is to drive the lifting platform 3 to move up and down through the hydraulic cylinder 4, thereby moving the cutting machine body 1, which is fixed at the bottom of the lifting platform 3, closer to or away from the steel pipe, thus realizing the automatic cutting operation of the steel pipe. The lifting platform 3 and the guide support rod 11 slide together to ensure the stability and smoothness of the cutting process.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, it also includes a clamping assembly, which includes two sets of symmetrically arranged clamping plates 5. Two sets of inclined push blocks 6 are fixedly installed on the top of the clamping plates 5. The inclined push blocks 6 are located on both sides below the shrink sleeve 7. The inclined surfaces of the inclined push blocks 6 abut against the inner wall of the shrink sleeve 7. The shrink sleeve 7 is fixedly installed on the other side of the bottom of the lifting platform 3. The inner side of the clamping plates 5 abuts against both sides of the steel pipe. The outer side of the clamping plates 5 is fixedly connected to one end of two sets of sliding guide rods 13. The other end of the sliding guide rods 13 is fixedly installed with a limit plate 14. The sliding guide rods 13 are slidably installed on the mounting plate 15. The mounting plate 15 is fixedly installed on the processing table 12. A first spring 16 is slidably sleeved on the surface of the sliding guide rods 13. One end of the first spring 16 abuts against the limit plate 14, and the other end of the first spring 16 abuts against the mounting plate 15.

[0032] By setting up a clamping assembly, its function is to automatically clamp and release the steel pipe by raising and lowering the lifting platform 3 in the cutting assembly. When the lifting platform 3 is driven by the hydraulic cylinder 4 to descend, the shrink sleeve 7 moves down accordingly, squeezing the inclined push block 6 on the top of the clamping plate 5, so that the clamping plate 5 moves towards the sliding guide rod 13 to clamp the steel pipe, ensuring the stability of the steel pipe during cutting and improving the cutting accuracy. When the cutting is completed and the lifting platform 3 rises, under the action of the first spring 16, the clamping plate 5 automatically releases the steel pipe, and the steel pipe falls into the inclined channel 9 under gravity and is automatically discharged.

[0033] In a further preferred embodiment, such as Figure 1 and Figure 2 As shown, it also includes a discharge assembly, which includes a discharge trough 8. A ramp channel 9 is provided below the discharge trough 8. The discharge trough 8 is located directly below the lifting platform 3. The discharge trough 8 is opened on the surface of the processing table 12. The ramp channel 9 is fixedly connected to one side of the bottom of the processing table 12. A receiving box 17 is provided on one side of the bottom of the ramp channel 9.

[0034] By setting up the discharge component, its function is to provide an automated collection path for the cut steel pipe. After the cutting is completed, when the lifting platform 3 rises and the clamping component releases the steel pipe, the steel pipe falls into the discharge trough 8 on the surface of the processing table 12 by its own gravity. Then, it automatically slides down the inclined channel 9 into the receiving box 17 on the bottom side, realizing the automatic transfer of the steel pipe from the cutting station to the collection station without manual handling. This reduces the labor intensity of the operators and improves the continuity of the processing flow and production efficiency.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, two sets of support seats 18 are fixedly installed on the top of the processing table 12. One set of support seats 18 is located on one side of the discharge chute 8, and the other set of support seats 18 is located on the other side of the top of the processing table 12. A conveying assembly is also included, positioned between the two sets of support seats 18. The conveying assembly includes symmetrically arranged drive conveying wheels 19 and abutment conveying wheels 20. The drive conveying wheels 19 are rotatably mounted inside the fixed frame 21 and are connected to the output end of the motor 22. The motor 22 is fixedly mounted on the top of the fixed frame 21. The bottom of the fixed frame 21 is fixedly connected to the processing table 12. A connecting frame 23 is rotatably installed on the top and bottom of the conveyor wheel 20. The connecting frame 23 is slidably engaged with the fixed plate 24. Two sets of limiting rings 25 are fixedly installed on both sides of the fixed plate 24. A second spring 26 is slidably sleeved on the side of the connecting frame 23 near the conveyor wheel 20. One end of the second spring 26 abuts against the limiting ring 25, and the other end of the second spring 26 abuts against the fixed plate 24. The fixed plate 24 is fixedly installed on the processing table 12.

[0036] By setting up a conveying component, the steel pipe is automatically conveyed to the bottom of the cutting component. The motor 22 drives the active conveying wheel 19 to rotate, and the conveying wheel 20 is tightly attached to the active conveying wheel 19 under the elastic force of the second spring 26. The two work together to clamp the steel pipe and drive the steel pipe to be conveyed smoothly through friction. No manual handling is required, which provides continuous and precise feeding support for the subsequent cutting process and improves the overall processing efficiency.

[0037] In practical use, the device is moved to the designated position. First, the cutting parameters are set in the control box via PLC and HMI. Then, the motor 22 is started to drive the active conveyor wheel 19 to rotate. The clamping conveyor wheel 20, under the action of the second spring 26, clamps the steel pipe between the clamping conveyor wheel 20 and the active conveyor wheel 19 and conveys it to the bottom of the cutting assembly. When the steel pipe is in place, the hydraulic cylinder 4 drives the lifting platform 3 to descend, bringing the cutting machine body 1 closer to the steel pipe for cutting. At the same time, the shrink sleeve 7 squeezes the inclined push block 6 on the top of the clamping plate 5, so that the clamping plate 5 clamps the steel pipe to ensure stable cutting. After cutting, the lifting platform 3 rises, and the clamping plate 5 releases the steel pipe under the action of the first spring 16. The steel pipe falls into the discharge chute 8 and slides into the receiving box 17 along the inclined channel 9 to complete collection. The whole process is automatic and continuous, reducing the intensity and cost of manual operation and improving processing efficiency.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
