[0031] The processing equipment of the present invention is used for processing new energy vehicles. The processing equipment includes a support frame 10 and a plurality of processing mechanisms 20. The plurality of processing mechanisms 20 are arranged at intervals on the support frame 10. Each processing mechanism 20 includes a spindle 21 and a processing head 22 arranged on the spindle 21. Each processing mechanism 20 can be set to work independently. Since the processing equipment includes a plurality of processing mechanisms 20 that can work independently, the plurality of processing mechanisms 20 can process different features of parts at the same time, greatly improving the processing efficiency.

[0032] It should be noted that the plurality of processing mechanisms 20 includes two or more processing mechanisms 20 .

[0033] Specifically, the machining head 22 is a five-axis head.

[0034] In this embodiment, each processing mechanism 20 includes: a beam 23, which is slidably connected to the support frame 10; a first linear motor 24, which is driven and connected to the beam 23 to drive the beam 23 to move along a first preset direction; a first sliding part, which is slidably connected to the beam 23; a second linear motor 26, which is driven and connected to the first sliding part to drive the first sliding part to move along a second preset direction; a second sliding part, which is slidably connected to the first sliding part, and the spindle 21 is arranged on the second sliding part; a third linear motor 28, which is driven and connected to the second sliding part to drive the second sliding part to move along a third preset direction; wherein any two of the first preset direction, the second preset direction and the third preset direction are arranged perpendicularly to each other. It should be noted that the first preset direction, the second preset direction and the third preset direction can also be described as three axes of X, Y and Z.

[0035] In specific implementation, the spindle 21 is driven by a linear motor in the first preset direction, the second preset direction and the third preset direction. The linear motor can achieve high-speed propulsion. Compared with the screw drive or the gear rack drive, the moving speed is greatly improved, thereby improving the processing efficiency.

[0036] Optionally, the first sliding part is a saddle, and the second sliding part is a ram.

[0037] In this embodiment, each processing mechanism 20 includes a guide rail and a slider assembly, which includes a guide rail and a slider slidably connected to the guide rail; a guide rail and a slider assembly is arranged between the crossbeam 23 and the support frame 10, so that the crossbeam 23 slides relative to the support frame 10; a guide rail and a slider assembly is arranged between the first sliding part and the crossbeam 23, so that the first sliding part slides relative to the crossbeam 23; a guide rail and a slider assembly is arranged between the second sliding part and the first sliding part, so that the second sliding part slides relative to the first sliding part.

[0038] In this embodiment, each processing mechanism 20 includes multiple cooling members 29, and the multiple cooling members 29 include a first cooling member, a second cooling member and a third cooling member.

[0039] In specific implementation, the higher the linear motor movement speed, the greater the current required and the greater the heat generated. If the internal cooling efficiency cannot keep up, the high-speed motion state will be difficult to maintain. The speed needs to be reduced to lower the temperature of the linear motor, and the processing efficiency is correspondingly reduced. This problem can be solved by providing the above-mentioned external cooling component.

[0040] Specifically, the first linear motor 24 is connected to the cross beam 23 through the first cooling member, so that the first cooling member is in contact with the first linear motor 24 for heat exchange; the second linear motor 26 is connected to the first sliding part through the second cooling member, so that the second cooling member is in contact with the second linear motor 26 for heat exchange; the third linear motor 28 is connected to the second sliding part through the third cooling member, so that the third cooling member is in contact with the third linear motor 28 for heat exchange.

[0041] Specifically, the cooling member 29 includes a main body 291 , in which a cooling channel 292 is disposed. The cooling channel 292 is used for passing a coolant.

[0042] In specific implementation, since the linear motor is directly connected to the main body 291, a cooling channel 292 is arranged inside the main body 291 to cool the main body 291, which is equivalent to adding an external cooling source for the linear motor. The cooling efficiency of the linear motor is improved, so that it can maintain a high-speed motion state for a longer time, and the processing efficiency can also be improved.

[0043] Specifically, the main body 291 is a plate-like structure; the cooling channel 292 includes a plurality of first cooling passages 293 , which are arranged at intervals along a first arrangement direction, and both ends of each first cooling passage 293 extend to the end of the main body 291 .

[0046] In this embodiment, each processing mechanism 20 includes a tool magazine 30, and the tool magazine 30 is arranged on the support frame 10. In this way, multiple processing heads 22 process different features of parts at the same time, and multiple tool magazines are equipped at the same time, which greatly improves the processing efficiency.

[0047] Specifically, the support frame 10 includes a base 11, a column 12, a base cross beam 13 and a connecting beam 14. The base 11 is used to be set on the installation foundation and is an integrated casting, which is used to support the entire support frame 10. Optionally, there are two processing mechanisms 20, and there are four columns 12, and the four columns 12 are installed at the four corners of the base 11; two tool magazines 30 are respectively installed in the upper hollows of the two columns 12 on the same side; the two base cross beams 13 are respectively connected and fixed by the two columns 12 on the same side; the parallelism of the base cross beams 13 is ensured by connecting the two connecting beams 14 of the columns 12; and the two cross beams 23 span between the two base cross beams 13.

[0048] The processing equipment of the present invention uses a linear motor drive to increase the spindle acceleration and moving speed, thereby improving processing efficiency; however, the linear motor generates a lot of heat when running at high speed, and the internal cooling efficiency is insufficient, which is transmitted to the installation surface to cause thermal deformation, affecting the processing accuracy, so a cooling part is provided to solve this problem.

[0049] The present invention solves the following technical problems: 1. Single beam single spindle structure, screw drive or gear rack drive, low processing efficiency. 2. High heat generated by linear motor at high speed, insufficient internal cooling efficiency, thermal deformation caused by heat transfer to the installation surface, affecting processing accuracy.

Specifically, multiple processing mechanisms are adopted, multiple spindles and processing heads are processed simultaneously, shortening the processing cycle; linear motor drive is adopted to increase acceleration and moving speed, and improve processing efficiency; adds cooling parts at the installation of the linear motor, and the synchronous action of internal cooling and external cooling improves cooling efficiency, while reducing the influence of thermal deformation and ensuring processing accuracy.
