Description
Technical Field
[0001] The utility model relates to the technical field of air-cooled electric spindles, in particular to a fast-cooling air-cooled electric spindle. Background Art
[0002] An electric spindle combines the spindle motor and the machine tool spindle into one. This involves using a housingless motor whose hollow rotor is directly mounted on the machine tool spindle with an interference fit. The stator, which has a cooling jacket, is installed in the housing of the spindle unit, forming a built-in motor spindle, also known as an electric spindle. Most electric spindles use air-cooled electric spindles for heat dissipation. This process typically involves high-pressure gas generated by an air pump or compressor. After filtering and drying, the gas is steadily pumped into the top of the electric spindle. Inside the electric spindle, the air flows through components such as air bearings, removing the heat generated by high-speed rotation and flowing out from the bottom of the electric spindle, thereby achieving effective heat dissipation. The air-cooling system is relatively simple. Air-cooled electric spindles play an important role in modern machining due to their unique heat dissipation method, high speed, high precision, and stability. However, the heat dissipation effect may be affected by factors such as ambient temperature and wind speed, resulting in reduced performance, system stability, and work efficiency. Utility Model Content
[0003] The purpose of the present utility model is to provide a fast-cooling air-cooled electric spindle, which reasonably solves the problem that the heat dissipation effect may be affected by factors such as ambient temperature and wind speed, resulting in performance degradation, system stability degradation, and work efficiency degradation, so as to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a fast-cooling air-cooled electric spindle, comprising an electric spindle, a protective shell with a cooling circulation effect fixedly installed on the electric spindle, a piston assembly with an air-cooling ratio adjustment effect fixedly installed on the protective shell, a fan with an air-cooling heat dissipation effect fixedly installed on the electric spindle, the protective shell comprising an outer shell, a threaded groove provided inside the outer shell, a nozzle pipe fixedly installed on one side of the lower end of the outer shell; the piston assembly comprising an access pipe, an A pipe and a B pipe installed on one side of the access pipe, a piston pipe being connected to one side of the A pipe and the B pipe, an A piston being installed inside the piston pipe, an A piston rod being fixedly installed on the A piston, a B piston being installed inside the piston pipe, a B piston rod being installed on the B piston, a B pipe being fixedly installed on one side of the piston pipe, and a C pipe being fixedly installed on one side of the B pipe.

[0006] Optionally, the B piston and the B piston rod pass through the A piston rod and move on the A piston rod.
[0007] Optionally, both the A piston rod and the B piston rod are fixedly mounted with an A handle and an access pipe for pulling.
[0008] Optionally, the A piston is arranged on the air outlet of the A pipe and the piston pipe to adjust the air outlet size of the two.
[0009] Optionally, the B piston is arranged between the access pipe and the b pipe to adjust the air outlet size of the two.
[0010] Optionally, a fan is provided on the electric spindle, and the fan transmits electric energy through a power supply interface and rotates to dissipate heat inside the electric spindle.
[0011] Optionally, the fan is connected to a C-pipe, which provides cold air to the fan to assist in dissipating heat inside the electric spindle.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the cold air is connected to the pipe and is divided into two parts through the A pipe and the B pipe. The cold air outlet ratio of the A pipe 302 and the piston pipe 304 is adjusted through the A piston. The cold air outlet ratio between the B piston adjustment pipe 301 and the b pipe 311 is adjusted. A part of the cold air enters the electric spindle through the rotation of the fan to assist in heat dissipation of the interior of the electric spindle, and the other part of the cold air is transported to the outer shell and circulated through the outer shell to dissipate heat to the outer surface of the electric spindle. After the circulating cold air is discharged through the nozzle pipe, it can also dissipate heat for the rotor head that is cutting during work and clean the dust generated by the rotor head and objects during work, which reasonably solves the problem that the heat dissipation effect may be affected by factors such as ambient temperature and wind speed, resulting in performance degradation, system stability degradation, and work efficiency degradation.

[0020] The protective shell 2 includes a shell 201 with a protective effect to protect the internal device. The shell 201 is provided with a threaded groove 202 with a cold air circulation effect to dissipate heat from the outer surface of the electric spindle 1. A nozzle pipe 203 is fixedly installed on one side of the lower end of the shell 201 to discharge the circulating cold air. At the same time, it dissipates heat to the cutting rotor during operation and cleans the dust generated by the rotor and objects during operation.
[0021] The piston assembly 3 includes an access pipe 301 for connecting cold air and transmitting cold air. A pipe 302 and B pipe 303 are installed on one side of the access pipe 301 to transmit cold air. Pipe A 302 and pipe B 303 are connected to one side of the piston pipe 304 to transmit cold air. It is a piston adjustment place. A piston 305 is installed inside the piston pipe 304 to adjust the size ratio of cold air output relative to the pipe. The A piston 305 is arranged on the air outlet of the A pipe 302 and the piston pipe 304 to adjust the size of cold air output from the two. The A piston rod 306 is fixedly installed on the A piston 305 to pull the piston to operate. The B piston 308 is installed inside the piston pipe 304 to adjust the size ratio of cold air output relative to the pipe. A pipe b 311 is fixedly installed on one side of the piston pipe 304. A pipe c 312 is fixedly installed on one side of the b pipe 311 to transmit cold air. The B piston 308 is arranged between the access pipe 301 and the b pipe 311 to adjust the size of cold air output from the two. The B piston A B piston rod 309 is installed on 308 to pull the piston to operate. The B piston 308 and the B piston rod 309 pass through the A piston rod 306 and move on the A piston rod 306 without interfering with each other, while adjusting the desired cooling air ratio. The A handle 307 and the access pipe 301 are fixedly installed on the A piston rod 306 and the B piston rod 309 for pulling, thereby driving the A piston 305 and the A piston rod 306 to adjust the proportion of cold air delivered by the pipe respectively. The piston pipe 304 is fixedly installed on the shell 201, and delivers cold air to the inside of the shell 201 to dissipate heat on the outer surface of the electric spindle 1. At the same time, a fan 4 is provided on the electric spindle 1. The fan 4 transmits electrical energy through the power interface 401, drives the rotation, and dissipates heat inside the electric spindle 1. The fan 4 is connected to the c pipe 312 for delivering cold air. The c pipe 312 provides cold air to the fan 4. When the cold air rotates with the fan 4, it enters the electric spindle 1 to assist in dissipating heat inside the electric spindle 1.
[0022] Working principle: The cold air is connected to the pipe 301 and is divided into two parts through the A pipe 302 and the B pipe 303. The two parts of cold air pass through the A piston 305, respectively, on the air outlet of the A pipe 302 and the piston pipe 304, to adjust the ratio of the cold air output of the two. The B piston 308 adjusts the pipe 301 and the B pipe 311, to adjust the ratio of the cold air output of the two. A part of the cold air enters the electric spindle 1 through the rotation of the fan 4 to assist in the heat dissipation of the internal part of the electric spindle 1, and the other part of the cold air is transported to the shell 201 and passes through the shell 2 01 circulates to dissipate heat from the outer surface of the electric spindle 1. After the circulated cold air is discharged through the nozzle pipe 203, it can also dissipate heat from the cutting rotor during operation and clean the dust generated by the rotor and the object during operation.
