Description

Technical Field

[0001] This utility model relates to the industrial and mining fields, specifically a clamping fixture for processing large motors. Background Technology

[0002] In the machining of motor parts such as motor shafts and end caps, the bottlenecks faced by low-precision machine tools in repair workshops or small production lines are: the fixed main cutting edge angle of traditional tool holders cannot be adapted to the stress concentration areas of non-standard chamfers of 15° and 20°, resulting in frequent tool breakage; sand holes and irregular surfaces of cast iron end cap blanks cause intermittent cutting, which aggravates wear and lacks high-pressure internal cooling to remove chips, and long chips entanglement further reduces machining stability; low work efficiency and reliance on experience, the complex tool changing mechanism of existing machine tools is costly and structurally redundant, making it difficult to promote on simple machine tools. There is an urgent need for a precision machining fixture with a simplified structure, supporting stepless adjustment of the main cutting edge angle and integrating directional internal cooling.

[0017] 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.

[0018] A main cutting edge angle adjustment fixture for turning motor parts includes a main cutting body 1 and a rotating body 6. The rotating body 6 has cutting edge grooves at both ends, and the cutting edge is fixed in the cutting edge grooves by locking screws 10. A cylinder 61 at the bottom of the rotating body 6 forms a clearance fit with a hole inside the main cutting body 1. The cylinder 61 is cylindrical inside the main cutting body 1, and a locking nut 9 is located below the cylinder 61, screwed to the bottom of the cylinder 61. The main cutting body 1 includes an upper spray pipe 3 at the top and a lower spray nozzle 8 at the front. The upper spray pipe 3 communicates with a horizontal channel 32 inside the main cutting body. One end of the horizontal channel 32 is connected to a connecting pipe 33, and the other end is connected to a vertical channel 31. The vertical channel 31 is arranged horizontally below, passing around the cylinder 61 at the bottom of the rotating body 6 and extending to the outer wall of the main cutting body 1, forming the lower spray nozzle 8 on the main cutting body 1.

[0019] There are two lower nozzles 8, which are respectively located on adjacent surfaces at the front end of the main cutter body 1, with the water outlet direction facing the cutting edge of the lathe tool.

[0020] The upper nozzle 3 has a C-shaped structure, and its lower end is connected to the horizontal channel 32 by a thread.

[0021] The two blade slots of the rotating body 6 are respectively equipped with obtuse-angled blade tip 7 and acute-angled blade tip 5, and the blade tips of the two are located at the outermost edge of the corresponding blade slot.

[0022] The coolant spray direction of the upper nozzle 3 and the lower nozzle 8 can be finely adjusted by the nozzle diameter or spray angle to adapt to the cutting requirements of different materials.

[0023] The locking nut 9 at the bottom of the rotating body 6 has a sawtooth thread, which engages with the external thread of the cylinder 61 for locking.

[0024] The working principle of this utility model is as follows:

[0025] The rotating body 6 rotates freely through the clearance fit between the bottom cylinder 61 and the main cutter body 1. After adjusting the main cutting edge angle, the bottom sawtooth thread locking nut 9 is tightened to directly press the end face of the cylinder 61 to achieve rigid fixation. The coolant is split through the horizontal channel 32: one path flows horizontally around the cylinder 61 base through the vertical channel 31 and is then precisely sprayed from the double lower nozzles 8 at the front end of the main cutter body 1 to the cutting edge tip. The other path covers the cutting area of ​​the front cutter face through the C-shaped upper nozzle 3. Obtuse-angle cutting edge inserts 7 and acute-angle cutting edge inserts 5 are respectively installed on the outermost side of the blade grooves at both ends of the rotating body 6. The cutting edge is maximized under the stepless adjustment of the main cutting edge angle. The integrated locking mechanism and directional cooling work together to overcome the bottleneck of high-flexibility machining in low-precision machine tools. After the stepless adjustment of the main cutting edge angle is achieved, the radial force can be further reduced by using obtuse-angle and acute-angle cutting edge inserts, thereby further reducing vibration.
