Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a cutting machine for processing mechanical parts. Background Technology

[0002] With the progress and development of society, more and more machines are used in life. Machines are assembled from a large number of parts. In order for the various parts of the machine to work together perfectly, cutting machines are needed to process and cut the machine parts.

[0003] Chinese utility model patent CN214023740U discloses a cutting device for machining mechanical parts. In use, the lower leg presses against the side plate of a sliding shaft plate, causing the connecting shaft to move on a locking block. This brings the other side plate of the sliding shaft plate into contact with the mechanical part, securing it to the cutting device. After the lower leg separates from the sliding shaft plate, the mechanical part can be easily removed, saving cutting time and facilitating adjustment of the cutting position. A scratch-prevention plate is moved downwards on the fixed plate, bringing it into contact with the top surface of the mechanical part. The palm of the hand presses down on the top surface of the scratch-prevention plate to prevent the mechanical part from jumping. The cutting blade rotates, cutting the mechanical part and preventing accidental injury to the operator, ensuring operator safety. However, this solution has the following shortcomings:

[0004] Operators need to be close to the equipment to fix the workpiece, and the cutting disc frame needs to be manually driven to rotate and cut. The debris generated during cutting is easy to splash, making the whole process time-consuming, labor-intensive, and unsafe. Summary of the Invention

[0005] The present invention aims to address the shortcomings of the prior art by providing a cutting machine for machining mechanical parts.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: A cutting machine for machining mechanical parts includes a cutting worktable and a workpiece positioning table arranged adjacent to each other.

One end of the top of the first sliding plate 4 is provided with a support column 5, and the top of the support column 5 is rotatably connected to a support plate 6 through a hinge. The other end of the top of the first sliding plate 4 is rotatably connected to a first hydraulic cylinder 7 through a hinge. The telescopic end of the first hydraulic cylinder 7 is rotatably connected to the bottom of the support plate 6.

[0028] like Figure 2As shown, the top of the support plate 6 is provided with a cutting mechanism. The cutting mechanism includes a motor 14 installed on the top of the support plate 6 away from the workpiece positioning table 2, and a bearing seat 15 fixed to the other end of the top of the support plate 6. A rotating shaft 16 is rotatably connected inside the bearing seat 15. A blade 17 is fixed to one end of the rotating shaft 16, and the other end is connected to the main shaft of the motor 14 by a belt drive. A second protective cover 18 is sleeved on the upper part of the blade 17. A bracket 19 is provided between the outer wall of the second protective cover 18 and the top of the support plate 6.

[0029] The workpiece positioning table 2 is provided with a pair of second guide rails 8 on the top, and a pair of second sliding plates 9 are slidably mounted on the second guide rails 8. Several second sliders 20 are provided at the bottom of the second sliding plates 9. The second sliders 20 are slidably mounted on the second guide rails 8, and the outer side of the second sliders 20 is threaded with clamping bolts 21. The top of the two second sliding plates 9 is detachably equipped with a workpiece fixing mechanism. A first protective cover 10 is slidably mounted on the side of the workpiece positioning table 2 away from the cutting table 1. A third guide rail 24 is provided on the side of the workpiece positioning table 2 away from the cutting table 1. The first protective cover 10 slides along the third guide rail 24.
