Description

Technical Field

[0001] The present application relates to the field of nozzles, and in particular to a swing chip removal nozzle. Background Art

[0002] The machine tool nozzle is an important component of machine tool equipment. Its main function is to accurately spray cutting fluid or coolant to the contact area between the workpiece and the tool. The design and performance of the nozzle directly affect the efficiency of the cutting process, the durability of the tool, the surface quality of the workpiece and the processing accuracy.

[0003] Machine tool nozzles are mostly designed with fixed or simple adjustable structures. Fixed nozzles have fixed spray angles and ranges, which are suitable for simple processing scenarios. Adjustable nozzles, on the other hand, adjust the spray angle and range by changing the nozzle structure or adding an adjustment mechanism to meet different processing requirements.

[0004] At present, conventional swing nozzles all require a power source to drive the nozzle to achieve swinging, and the power source is a machine or a cylinder, which leads to a complex overall structure and high cost. Utility Model Content

[0011] The length of the hose is Xa, the distance between the fixed connection part and the nozzle is Xb, Xa is greater than Xb, and the hose is in a bent state so that the nozzle direction forms an angle with the length direction of the swing link.

[0012] By adopting the above technical solution, because the length of the hose is greater than the distance between the fixed connector and the nozzle, the hose is bent, so that the nozzle direction forms an angle with the length direction of the swing link. When the nozzle sprays oil (coolant), a reaction force is generated, causing the nozzle to deflect in the opposite direction.

[0013] The reaction force of the sprayed liquid is used to change the angle of the nozzle, thereby achieving fan-shaped spraying, increasing the spraying area, and improving the chip flushing effect. The present application uses the reaction force of the sprayed liquid to change the angle of the nozzle, without using other power sources (motor or cylinder), realizes the swing of the nozzle, simplifies the structure, and reduces the production cost of the swing nozzle.

[0014] Optionally, there are two swing links and they are symmetrically arranged.

[0015] By adopting the above technical solution, the swing link serves to limit the nozzle, and the symmetrical setting is more stable.

[0016] Optionally, the swing connecting rod is connected to the fixed connecting piece and the nozzle through a shoulder bolt, the shoulder bolt passes through the swing connecting rod, and the unthreaded shoulder portion of the shoulder bolt contacts the hole wall of the swing connecting rod.

[0017] By adopting the above technical solution, the structure is simple and the installation and disassembly are convenient.

[0018] Optionally, the shoulder bolt sleeve is provided with a gasket, which is located on the side of the swing link facing away from the shoulder bolt head.

[0019] Optionally, the threaded portion of the shoulder bolt is coated with an adhesive.

[0024] By adopting the above technical solution, the swing amplitude of the nozzle can be adjusted by adjusting the length of the swing connecting rod.

[0025] Optionally, the swing connecting rod includes an upper connecting rod connected to a fixed connecting member, a lower connecting rod connected to the nozzle, and a locking bolt fixing the upper connecting rod and the lower connecting rod. The upper connecting rod is provided with a plurality of threaded holes, and the locking bolt passes through the lower connecting rod and is threadedly connected to the upper connecting rod.

[0026] By adopting the above technical solution, the locking bolt is connected to different threaded holes, thereby achieving adjustable length of the swing connecting rod.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The swing link is used to limit the distance between the fixed connector and the nozzle, and the length of the hose is greater than the distance between the fixed connector and the nozzle.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] The embodiment of the present application discloses a swinging chip removal nozzle.

[0037] Example 1: Reference Figure 1 , the oscillating chip removal nozzle includes:

[0038] The fixed connection member 100 is used to be fixed to the machine tool and is also used to be connected to an oil circuit connected to a pressure source. The pressure source is an oil pump or other device for increasing liquid pressure. The liquid delivered is a coolant or a cutting fluid.

[0039] Nozzle 200;

[0040] A hose 300, one end of which is connected to the fixed connection member 100, and the other end of which is connected to the nozzle 200, and the hose 300 connects the fixed connection member 100 and the nozzle 200;

[0041] A swing link 400, wherein there are two swing links 400 and they are symmetrically arranged, one end of the swing link 400 is hinged to the fixed connection member 100, and the other end is hinged to the nozzle 200;

[0042] Reference Figure 2 and Figure 3 , wherein the length of the hose 300 is Xa, the distance between the fixed connector 100 and the nozzle 200 is Xb, and Xa is greater than Xb. Because the length of the hose 300 is greater than the distance between the fixed connector 100 and the nozzle 200, the hose 300 is in a bent state, so that the nozzle 200 forms an angle a with the length direction of the swing link 400. When the nozzle 200 sprays oil (coolant), a reaction force F is generated, and the reaction force F is decomposed into Fx and Fy. Under the action of one of the component forces Fx, the nozzle 200 deflects in the opposite direction.

[0043] Reference Figure 3 After the deflection is completed, the nozzle 200 faces the other side, and the nozzle 200 also forms an angle a with the length direction of the swing connecting rod 400. Under the action of the reaction force component Fx, it deflects again to achieve reciprocating swing. The nozzle 200 swings back and forth to achieve fan-shaped spraying, increase the spraying area, and improve the chip flushing effect. The reaction force of the sprayed liquid is used to change the angle of the nozzle 200, without the need to use other power sources (motor or cylinder), so that the nozzle 200 can be swung, the structure is simplified, and the manufacturing cost of the swing nozzle is reduced. In addition, by replacing hoses 300 of different lengths, different swing angles of the nozzle 200 can be obtained, thereby adjusting the range of the fan-shaped spraying area.

[0044] Reference Figure 1 The fixed connector 100 includes a hose connector 101 and an adapter 102. One end of the hose connector 101 is used to connect with the hose 300. The hose connector 101 is threadedly connected with the adapter 102. The adapter 102 is used to communicate with the oil circuit.

[0045] Reference Figure 1 The swing link 400 is connected to the hose connector 101 and the spray head 200 through the shoulder bolt 500. The shoulder bolt 500 is threadedly connected to the side wall of the swing link 400 and the hose connector 101. The shoulder bolt 500 is threadedly connected to the side wall of the spray head 200. The shoulder portion of the shoulder bolt 500 without threads contacts the hole wall of the swing link 400. The shoulder bolt 500 is sleeved with a gasket 501, and the gasket 501 is located on the side of the swing link 400 facing away from the head of the shoulder bolt 500.

[0046] In order to prevent loosening, the thread of the bolt portion of the shoulder bolt 500 is coated with adhesive to increase the stability between the shoulder bolt 500 and the fixed connection member 100 and between the shoulder bolt 500 and the nozzle 200.

[0047] The implementation principle of the swing chip removal nozzle disclosed in Example 1 of the present application is: because the length of the hose 300 is greater than the distance between the fixed connector 100 and the nozzle 200, the hose 300 is in a bent state, which causes the nozzle 200 to form an angle with the length direction of the swing connecting rod 400. When the nozzle 200 sprays oil (coolant), a reaction force is generated, causing the nozzle 200 to deflect in the opposite direction. The present application uses the reaction force of the sprayed liquid to change the angle of the nozzle 200, without the need to use other power sources (motor or cylinder), thereby achieving the swing of the nozzle 200, simplifying the structure, and reducing the manufacturing cost of the swing nozzle.

[0048] Embodiment 2: The difference from Embodiment 1 is: Figure 4 The swing link 400 is a lockable telescopic rod, and the swing amplitude of the nozzle 200 can be adjusted by adjusting the length of the swing link 400.

[0049] Specifically, the swing link 400 includes an upper link 401, a lower link 402 and a locking bolt 403. The upper link 401 is connected to the side wall of the hose connector 101 through a shoulder bolt 500. The lower link 402 is connected to the side wall of the spray head 200 through a shoulder bolt 500. The upper link 401 is provided with a plurality of threaded holes 404 along the length direction, and the locking bolt 403 passes through the lower link 402 and is threadedly connected to the upper link 401, thereby fixing the two. By connecting the locking bolt 403 with different threaded holes 404, the length of the swing link 400 can be adjusted.

[0050] In order to further improve the stability of the swing link 400, a through hole is opened in the length direction of the lower link 402, and a positioning pin 406 is provided at one end of the upper link 401. The positioning pin 406 is inserted into the through hole, thereby improving the firmness of the swing link 400 after adjusting the length.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
