The terminology used in the description herein is for describing the specific embodiments only and is not intended to be limiting of the application.

[0028] At present, when a machining center processes a product by using a tool, a spraying device is needed to spray cutting fluid to the tool for lubrication, cooling, cleaning and removing chips, etc. The liquid spraying pipe of the existing spraying device moves up and down along the axial direction of the main shaft of the fixed tool to spray the tool.

[0029] However, since the up-and-down movement position displacement of the liquid spraying pipe is limited, the spraying position of the cutting fluid is fixed. If the length of the tool exceeds the spraying position, the part exceeding the spraying position cannot be sprayed with the cutting fluid. If the length of the tool does not reach the spraying position, the position without the tool is sprayed, resulting in poor spraying effect, and different lengths of tools cannot be compatible, which leads to the inability to meet the existing processing requirements. In addition, under the combined operation of the vibration of each component in the machining center and the flow of the cutting fluid, the spraying pipe of the spraying device often deviates from the correct spraying position, so it is necessary to frequently manually adjust the spraying angle of the spraying pipe, resulting in high maintenance cost.

[0032] The embodiment of the present application also provides a machining system, which comprises the spraying device, a rack and a cutter arranged on the rack. The spraying device is arranged on one side of the cutter, and the liquid spraying direction of the liquid spraying pipe of the spraying device is perpendicular to the length direction of the cutter. The controller is used for controlling the driving member of the spraying device to drive the transmission mechanism to move according to the length of the cutter, so as to drive the liquid spraying pipe to rotate around the liquid spraying direction by a set angle to spray liquid towards the cutter.

[0033] During the machining of the product by the machining system, the controller controls the driving member to drive the transmission mechanism to move according to the length of the cutter, so as to drive the liquid spraying pipe to rotate around the liquid spraying direction by a set angle, so that the spraying direction of the liquid spraying pipe can be aligned with the tip of the cutter to spray liquid, and the debris generated during machining can be removed in time, and the machining efficiency of the machining system is improved.

[0040] Exemplarily, the first transmission member 141 can be a first gear, and the second transmission member 142 can be a second gear, wherein the second gear is a driving gear, and the first gear is a driven gear, the modulus of the first gear and the second gear is the same, and the pressure angle is equal. By meshing the second gear with the first gear, the torque can be efficiently transmitted, the energy loss can be reduced, and the transmission efficiency can be improved, so as to ensure the accuracy of the rotation of the liquid spraying pipe 161.

[0041] In some embodiments of the present application, in order to adapt to different application scenarios, the number of teeth of the first gear and the second gear can be the same or different. By reasonable gear design, the load can be evenly distributed to the first driving shaft 12 and the second driving shaft 13, so as to prolong the service life of the first driving shaft 12 and the second driving shaft 13, and then reduce the maintenance cost of the spraying device 100.

[0042] Meanwhile referring to Figure 3 As shown, the bottom of the accommodating cavity 111 is provided with a fixed plate 1111. The fixed plate 1111 separates the accommodating cavity 111 into a first accommodating cavity 1112 and a second accommodating cavity 1113. The transmission mechanism 14 is arranged in the first accommodating cavity 1112. The driving member 15 is arranged in the second accommodating cavity 1113.

Specifically, the first driving shaft 12 is rotatably connected to the fixing plate 1111 by the first bearing 124, and the second driving shaft 13 is rotatably connected to the fixing plate 1111 by the second bearing 131, which is conducive to reducing vibration and unbalanced force, ensuring that the first driving shaft 12 and the second driving shaft 13 can operate smoothly, and further ensuring the stability of the connection between the first driving shaft 12 and the first transmission member 141 and the connection between the second driving shaft 13 and the second transmission member 142.

[0044] In some embodiments of the present application, the bottom of the accommodating cavity 111 is further provided with a limiting plate 1114. The limiting plate 1114 is located between the driving member 15 and the inner wall of the shell 11 and abuts against the driving member 15.

[0045] In some embodiments of the present application, the driving member 15 is fixed by abutting against the limiting plate 1114, which prevents the driving member 15 from loosening during operation and ensures the stability of the position of the driving member 15.

[0046] In some embodiments of the present application, in order to further ensure the stability of the position of the driving member 15, the limiting plate 1114 can be fixedly connected to the bottom of the accommodating cavity 111 to prevent the limiting plate 1114 from moving. At the same time, in order to avoid the problem that the limiting plate 1114 collides with the inner wall of the shell 11 due to loosening of the driving member 15, there is a gap between the end face of the end of the limiting plate 1114 away from the driving member 15 and the inner wall of the shell 11.

[0047] In some embodiments of the present application, the liquid spraying mechanism 16 is provided with a moving groove 162. The length direction of the moving groove 162 is perpendicular to the axial direction of the center axis of the liquid spraying pipe 161. The moving groove 162 is used to accommodate the liquid spraying pipe 161.

[0048] In some embodiments of the present application, by setting the liquid spraying pipe 161 to move in the moving groove, the movement range of the liquid spraying pipe 161 is limited.

[0049] At the same time, referring to Figure 4 As shown in the drawings, the liquid spraying mechanism 16 is further provided with a first channel 163 and a second channel 164.

[0057] In some embodiments of the present application, the first limiting groove 123, the limiting member 18 and the second limiting groove 1411 cooperate to prevent the first transmission member 141 from being misaligned to cause the angle of rotation of the spray pipe to be inaccurate, and the spray direction of the liquid spray pipe 161 can be accurately aligned with the tip of the tool 22 to spray liquid, thereby improving the spraying effect of the spraying device 100.

[0058] In some embodiments of the present application, the spraying device 100 further comprises a cover plate 19. The cover plate 19 is buckled to the shell 11 to block the accommodation cavity 111.

[0059] In some embodiments of the present application, the cover plate 19 blocks the accommodation cavity 111 of the shell 11, which can effectively prevent dust, moisture and the like from entering the shell 11, thereby protecting the internal components of the accommodation cavity 111 from being contaminated or corroded, and reducing the maintenance cost of the spraying device 100.
