Description

Technical Field

[0001] The utility model belongs to the technical field of cutting mechanisms and relates to a four-knife continuous motor housing end face cutting mechanism. Background Art

[0002] The outer shell end face of the motor housing will be fine-machined by a professional cutting mechanism during the subsequent processing. The cutting work is mainly carried out by the CNC tool holder in the cutting mechanism. A cutting knife is installed on each side of the CNC tool holder. The CNC tool holder refers to a tool holder installed on a power turret and can be driven by a servo motor. The CNC tool holder is equipped with a servo motor to allow it to rotate accordingly according to the set program, and adjust the position of the cutting knife according to processing requirements. With the increasing complexity of the workpiece, the improvement of the precision level and processing efficiency, multi-axis and high-speed have become necessary conditions for machine tools. In addition to the functional complexity of machining centers, many new processing forms have been developed from early horizontal lathes to meet the needs of new era processing methods.

[0003] The existing cutting mechanism is equipped with corresponding moving parts, which can allow the CNC tool holder to move on the XY axis according to the set degree, and adjust the position in time to cut the end face of the motor housing. However, since the cutting position of the CNC tool holder will change during the movement, the contact point with the motor housing will also be different. The mechanism responsible for spraying coolant in ordinary lathes is fixed and cannot always move with the cutting tool, resulting in damage to the tool during the cutting period and reducing its service life.

[0028] In this embodiment, the CNC tool holder 2 is an existing technical equipment, which is mainly used in the processing of the machine tool 1. A corresponding servo motor is installed in the CNC tool holder 2, which can make it rotate regularly according to the set program. There are generally four cutting knives installed in the CNC tool holder 2, and each tool has a corresponding number. The device responsible for spraying coolant in the ordinary machine tool 1 is fixed and cannot be aligned with the working cutting knife at all times. Therefore, the working life of the cutting knife is greatly reduced. How the CNC tool holder 2 rotates and the technology of its movement along the XY direction in the machine tool 1 is not described.

[0029] Combination Figure 1 , Figure 2 As shown, the bolts 24 are installed through the edge of the top seat 23, and the top seat 23 is provided with threaded holes 33 at the places where the bolts 24 pass through. The bolts 24 are arranged regularly, and the housing 25 is located on the inner side of the bolts 24.

[0030] Furthermore, a total of twelve bolts 24 are installed through the top seat 23, so there are four bolts 24 on each side of the top seat 23. A cutting knife is installed on each side between the top seat 23 and the base 21, and the upper bolts 24 are against the cutting knife to fix it here.

[0031] Combination Figure 2 , Figure 6 As shown, the middle of the cylinder 31 is hollow, the cylinder 31 and the ring 32 are interconnected, and the diameter of the cylinder 31 is smaller than the ring 32. The housing 25 is inserted in the middle of the base 3, and the top height of the housing 25 is higher than the base 3.

[0032] Furthermore, the base 3 can be installed on the top base 23 by welding or the like, and the casing 25 passes through the base 3 . The height of the base 3 is lower than the casing 25 , and will not affect the assembly and disassembly of the casing 25 .

[0033] Combination Figure 1 , Figure 2 , Figure 3 As shown, the cavity 41 is connected to the outside by setting a hose at the injection port 43, and the limit grooves 42 are located on the upper outer wall of the cavity 41, and the limit grooves 42 are symmetrically arranged. The pipeline 5 is connected to the cavity 41, and the solenoid valve 51 is electrically connected to the central component 22, and the metal bellows 52 is connected to the pipeline 5.

[0034] Furthermore, a device for loading coolant is installed in the machine tool 1, and the cavity 41 is connected to the device for loading coolant by installing a hose in the injection port 43, so that the cavity 41 will be filled with coolant. When the central component 22 drives the CNC tool holder 2 to rotate, the corresponding cutting knife will also be aligned with the motor housing, and then the solenoid valve 51 here is opened, and the solenoid valves 51 at the other three locations are closed, and the coolant is sprayed on the cutting knife through the metal bellows 52 here, and the metal bellows 52 can be bent and deformed at will.

[0035] Combination Figure 2 , Figure 3 As shown, the limit plate 62 is inserted into the limit groove 42, and the size of the limit plate 62 is smaller than the limit groove 42, and the threaded hole 33 on the ring 32 corresponds to the limit groove 42. The bottom plate 63 is located on the ring 32, and the outer wall of one side of the bottom plate 63 is set to be arc-shaped. The bottom plate 63 is provided with a threaded hole 33, and the bottom plate 63 is mounted on the base 3 by bolts 24.

[0036] Furthermore, the limiting plate 62 is placed in the limiting groove 42, the bottom plate 63 falls on the ring 32, the threaded holes 33 on the bottom plate 63 and the ring 32 are aligned and fixed with bolts 24, and the outer wall of one side of the bottom plate 63 is set to an arc shape, so the bottom plate 63 and the outward end of the ring 32 will be flush without affecting the appearance.

[0037] The working principle of the utility model is:

[0038] Install the cavity 41 in the cooling component 4 with the injection port 43 facing upwards, place the cavity 41 on the casing 25, and then align the limit plate 62 with the limit groove 42 and insert it. At this time, the outer wall of the cavity 41 is tightly attached to the support rod 61, and then the bottom plate 63 falls on the ring 32. At this time, the threaded holes 33 on the ring 32 and the bottom plate 63 are aligned with each other, and then fixed by bolts 24, so that the bracket 6 is fixed on the base 3, and the cavity 41 is limited and fixed by the bracket 6 at four places to ensure its stability, and then a hose is used to install it on the injection port 43, and the other end of the hose is connected to the device for loading coolant on the machine tool 1, so that the inside of the cavity 41 will be filled with coolant.

[0039] The solenoid valve 51 is electrically connected to the central component 22. When the central component 22 drives the CNC tool holder 2 to make corresponding turns, so that different tools are aligned with the motor housing, the solenoid valves 51 at the corresponding positions of the corresponding tools will open, and the coolant inside the cavity 41 will flow to the metal bellows 52 through the pipe 5, and finally sprayed on the contact area between the cutting tool and the motor housing for cooling.

[0040] At the same time, the electromagnetic valves 51 at the other three locations will be closed. Only when the tool cuts the motor housing will the electromagnetic valves 51 at the corresponding locations work. The electromagnetic valves 51 work along with the numerical control tool holder 2.
