Description

Technical Field

[0001] The invention belongs to the field of processing equipment, and in particular relates to a cutting fluid spraying structure. Background Art

[0002] Cutting fluid is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and workpieces. Cutting fluid is scientifically compounded from a variety of super-functional additives. It has good cooling, lubrication, rust prevention, oil removal and cleaning, anti-corrosion, and easy dilution properties.

[0003] Most of the existing cutting fluid spraying structures for spraying cutting fluid are fixed, and the spraying direction of the cutting fluid is fixed; when the tool structure is moving for processing, the tool structure needs to move up and down, and the cutting fluid sprayed by the fixed cutting fluid spraying structure cannot cool and lubricate the tool structure well. In response to this situation, the prior art solves the problem of timely cooling and lubricating the tool structure to a certain extent by setting the cutting fluid spraying structure to be rotatable, so that the cutting fluid spraying structure can rotate synchronously with the up and down movement of the tool structure. However, the amount of cutting fluid sprayed by the existing cutting fluid spraying structure is insufficient, and the cooling and lubrication effects are still relatively poor. And when the cutting fluid spraying structure needs to move to avoid based on processing requirements, the existing cutting fluid spraying structure cannot move in the up and down directions and the front and back directions. Summary of the invention

[0004] The primary purpose of the present invention is to provide a nozzle swing device with adjustable position, the nozzle of which can swing and rotate synchronously with the up and down movement of the tool structure to timely cool and lubricate the tool structure; and the device has two nozzles, and the cutting fluid sprayed out has a better effect when used for cooling and lubrication.

[0005] Another object of the present invention is to provide a nozzle swing device with adjustable position, which can move in the up and down directions and the front and back directions.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows.

[0007] A nozzle swing device with adjustable position, characterized in that the device includes a nozzle mechanism and a two-axis motion mechanism for driving the nozzle mechanism to move in the up and down directions and the front and back directions, and the nozzle mechanism is arranged on the two-axis motion mechanism; the nozzle mechanism includes two nozzle assemblies for spraying cutting fluid, and a driving assembly for driving the nozzle assembly to rotate; the driving assembly is connected to any one of the nozzle assemblies, a transmission assembly is arranged between the two nozzle assemblies, and the two nozzle assemblies are connected to each other through the transmission assembly, and a nozzle for spraying cutting fluid is arranged on the nozzle assembly, and the extension lines of the nozzles of the two nozzle assemblies always intersect.

[0008] In the device, the drive assembly can be used to drive the nozzle assembly connected to the drive assembly to rotate, and when the nozzle assembly rotates, the transmission assembly drives another nozzle assembly to rotate at the same time, that is, the drive assembly controls the two nozzle assemblies to rotate at the same time; therefore, the nozzles of the two nozzle assemblies can follow the up and down movement of the external tool structure to rotate synchronously and adjust the position, so as to cool and lubricate the tool structure in time. And the two nozzles have better effect when spraying cutting fluid for cooling and lubrication.

[0009] Specifically, the extension lines of the two nozzles always intersect on the motion trajectory of the external tool structure; here, the external tool structure only moves in the up-and-down direction (Z axis) relative to the nozzle, because the device and the external tool structure move in other directions at the same time (XY axis); so when the two nozzles follow the up-and-down movement of the external tool structure to rotate synchronously to adjust their positions, the intersection of the cutting fluids sprayed by the two nozzles is always on the tool structure. And based on the setting of the two-axis motion mechanism, the nozzle mechanism can be driven to move in the up-and-down direction and the front-and-back direction, making it more convenient for the nozzle mechanism to avoid when it needs to (such as when the tool structure is changing the tool).

[0010] Furthermore, an angle less than 180° is formed between the two nozzle assemblies.

[0011] Furthermore, the transmission assembly includes a first bevel gear and a second bevel gear, one end of the two nozzle assemblies is connected to the first bevel gear and the second bevel gear respectively, and the first bevel gear and the second bevel gear are meshed. Through the transmission of the first bevel gear and the second bevel gear, the two nozzle assemblies can be arranged at an angle.

[0012] Furthermore, the transmission assembly includes a coupling. The principle of the coupling is the prior art. By setting the coupling, there is no rotation error.

[0013] Furthermore, the nozzle assembly includes a nozzle shaft, the nozzle is arranged on the nozzle shaft, the driving assembly is drivingly connected to any one of the nozzle shafts; and the transmission assembly is respectively connected to both ends of the two nozzle shafts.

[0014] Furthermore, the driving assembly is a servo motor, and the output shaft of the servo motor is drivingly connected to one end of any nozzle shaft.

[0015] Furthermore, the nozzle mechanism also includes a shell, the two nozzle shafts and the transmission assembly are arranged in the shell, and the shell is provided with two rotation avoidance grooves corresponding to the two nozzles for the rotation of the nozzles, and the nozzles extend outward through the corresponding rotation avoidance grooves; the driving assembly is arranged at one end of the shell and is connected to the corresponding nozzle shaft driving connection; the shell is also connected to two water inlet interfaces for inputting cutting fluid, and the two water inlet interfaces for inputting cutting fluid are respectively connected to the two nozzle shafts.

[0016] Furthermore, a flow channel is arranged in the nozzle shaft, the nozzle is fixedly arranged on the corresponding nozzle shaft, and the nozzle is connected to the flow channel; a liquid inlet ring groove is arranged around the nozzle shaft, a liquid inlet hole connected to the flow channel is arranged in the liquid inlet ring groove, and the water inlet interface is connected to the liquid inlet ring groove. The cutting fluid enters the housing and the liquid inlet ring groove through the water inlet interface, enters the flow channel through the liquid inlet hole, and is sprayed out from the nozzle through the flow channel.

[0017] Furthermore, the nozzle shaft is provided with sealing ring grooves on both sides of the liquid inlet ring groove, and the sealing ring grooves are provided with sealing rings for preventing leakage of cutting fluid.

[0018] Furthermore, the nozzle shaft is provided with sealing ring grooves at both sides of the nozzle, and sealing rings are provided in the sealing ring grooves for preventing leakage of cutting fluid.

[0019] Furthermore, the two-axis motion mechanism includes a movable plate, a connecting plate and a mounting bracket, the nozzle mechanism is arranged at the lower side of the mounting bracket, the connecting plate is movably connected to the upper side of the mounting bracket through a guide rail structure, so that the connecting plate and the mounting bracket can move relative to each other in the front-rear direction; an oblique groove is arranged on the movable plate, and the mounting bracket is movably connected to the movable plate through the oblique groove. The oblique groove here refers to a groove inclined relative to the horizontal plane. Specifically, based on the setting of the oblique groove, the mounting bracket can only make oblique movements when in the oblique groove, that is, it moves in the up-down direction and the front-rear direction at the same time; and the connecting plate can be connected to an external driving structure, and the connecting plate is driven to move up and down by the external driving structure; when the connecting plate moves up and down, it drives the mounting bracket to move up and down, and at the same time, the mounting bracket and the connecting plate move relative to each other in the front-rear direction through the guide rail structure to realize the oblique movement of the mounting bracket.

[0020] Furthermore, a sliding member is fixed to the side end of the mounting bracket, a cam roller is arranged on the sliding member, and two straight grooves are also arranged on the movable plate, and the two straight grooves are respectively arranged at the upper and lower ends of the oblique groove to connect with the oblique groove; the cam roller is movably arranged in the two straight bars and the oblique groove. When the cam roller moves in the two straight grooves, the mounting bracket only moves in the up and down directions, and when the cam roller moves in the oblique groove, the mounting bracket moves obliquely. The two-axis motion mechanism has a simple structure and low cost, fast movement speed, and is safe and reliable; there will be no problem that other actuators such as motors and cylinders need to be controlled and confirmed to be safely in place, which will cause pauses.

[0021] Furthermore, the mounting bracket is provided with two nozzle mechanisms, the two nozzle mechanisms are arranged opposite to each other, and the extension lines of the four nozzles on the two nozzle mechanisms always intersect, specifically, the extension lines of the four nozzles on the two nozzle mechanisms always intersect on the motion trajectory of the external tool structure.

[0022] The beneficial effect of the present invention is that, in the present invention, through the setting of the driving assembly, the nozzle assembly connected to the driving assembly can be driven to rotate, and when the nozzle assembly rotates, the transmission assembly drives another nozzle assembly to rotate at the same time, that is, the driving assembly controls the two nozzle assemblies to rotate at the same time; therefore, the nozzles of the two nozzle assemblies can follow the up and down movement of the external tool structure to rotate synchronously and adjust the position, and cool and lubricate the tool structure in time. And the two nozzles have better effects when spraying cutting fluid for cooling and lubrication. Specifically, the extension lines of the two nozzles always intersect on the motion trajectory of the external tool structure; here, the external tool structure only moves in the up and down direction (Z axis) relative to the nozzle, because the device and the external tool structure move in other directions at the same time (XY axis); therefore, when the two nozzles follow the up and down movement of the external tool structure to rotate synchronously and adjust the position, the intersection and convergence of the cutting fluid sprayed by the two nozzles is always on the tool structure. And based on the setting of the two-axis motion mechanism, the nozzle mechanism can be driven to move in the up and down direction and the front and back direction, so that the nozzle mechanism is more convenient when it needs to avoid (such as when the tool structure is changing the tool).
