Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a diverting capillary tube. Background Technology

[0002] Existing low-temperature micro-cooling and lubrication systems mostly employ vortex tube single-stage cooling devices. When this device is used alone for cooling tools and workpieces, if a lower temperature is required, the exhaust volume at the hot end of the compressed air must be increased, resulting in a very small usable cold air flow. This makes it impossible to achieve the desired cooling effect in metal cutting or product cooling. When using vortex tube single-stage cooling devices, existing vortex tube devices suffer from exhaust and heat dissipation problems at the hot end, preventing the cold end air temperature from dropping rapidly enough to achieve the goal of rapid product cooling within a limited processing time. In summer, as the ambient temperature rises, the compressed air temperature also rises, resulting in a relatively high cold air temperature obtained using vortex tube single-stage cooling, which is far from meeting the temperature requirements for low-temperature cooling.

[0003] As attached Figure 1 The existing cooling device, as shown, has a nozzle assembly that, depending on the actual working conditions, is attracted or installed near the machine tool cutting tool or processed parts by a strong magnetic base assembly; the air inlet pipe is connected to the cooling air outlet pipe through a connector; the capillary assembly is connected to the tank assembly and the main nozzle seat through fittings and connectors; and the temperature sensor assembly is connected to the digital display controller through wires. However, the above structure has the following problems: the capillary and the main nozzle seat are directly connected through a quick-connect air pipe. However, after the capillary is inserted, the quick-connect air pipe clamps the capillary with its internal spring plate to achieve connection and sealing. The capillary located at the outer end of the quick-connect air pipe is easily pulled and tilted by external force, which will cause the internal spring plate of the quick-connect air pipe to be subjected to external tensile force. After a long time, leakage is likely to occur at the connection between the capillary and the quick-connect air pipe. Utility Model Content

[0004] The purpose of this invention is to provide a diversion capillary that can improve the stability of the connection between the capillary body and the main nozzle seat and reduce liquid leakage.

[0005] To achieve the above objectives, this utility model provides a diversion capillary, including a capillary body, which is detachably connected to a main nozzle seat, and also includes a stabilizing mechanism;

[0006] The stabilizing mechanism includes a snap ring seat, a lower support seat, an upper support seat, a threaded cap, an abutment ring, a limiting snap ring, a first positioning element, and a second positioning element. The snap ring seat is detachably mounted on the main nozzle seat. The abutment ring is integrally provided on the lower support seat. The first positioning element is symmetrically provided on the abutment ring. The first positioning element is slidably inserted into the mating hole on the main nozzle seat. The second positioning element is provided at the bottom of the upper support seat. The second positioning element is slidably inserted into the mating hole on the lower support seat. The threaded cap is threadedly connected to the lower support seat and the upper support seat respectively, and the capillary body passes through the center hole of the threaded cap. The limiting snap ring is detachably connected to the snap ring seat and abuts against the abutment ring.

[0007] The first positioning element is a cylindrical pin, which is symmetrically arranged on the abutment ring during installation and can be installed or removed by rotating it with an Allen wrench.

[0008] The second positioning element is a positioning cylinder, which is integrally and symmetrically arranged at the bottom of the upper support base. During installation, it can be slidably inserted into the positioning mating hole on the lower support base.

[0009] The main nozzle seat is equipped with multiple main output nozzles via a universal tube mechanism.

[0010] The diversion capillary also includes an isolation mechanism, which includes a mating seat and a rubber ring. The mating seat is detachably connected to the threaded cap and is located on the side of the threaded cap away from the limiting snap ring. The rubber ring is disposed in a mounting groove in the inner hole of the mating seat and is slidably connected to the capillary body.

[0011] This utility model discloses a diversion capillary tube. When connecting the capillary tube body to the quick-connect duct connector on the main nozzle seat, the threaded cap and lower support seat are first sequentially fitted onto the outer side of the connecting end of the capillary tube body. Then, the end of the capillary tube body is inserted into the quick-connect duct connector on the main nozzle seat. Further, the lower support seat is positioned by a first positioning member and limited by a limiting spring. The upper support seat is then installed by a second positioning member. Finally, the threaded cap is installed on the external threaded end formed on the lower and upper support seats. In this application, after the capillary tube body is connected to the quick-connect duct connector on the main nozzle seat, a limiting structure is formed on the outer side of the quick-connect duct connector, ensuring that the connection between the capillary tube body and the quick-connect duct connector is always in a collinear mating position, avoiding pulling and tilting caused by external force. The connection between the capillary tube body and the main nozzle seat is more stable, thereby improving the stability of the connection between the capillary tube body and the main nozzle seat and reducing liquid leakage.

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1:

[0024] like Figures 2 to 5 As shown, where Figure 2 This is a schematic diagram of the overall structure of the shunt capillary. Figure 3 This is a structural schematic diagram of the lower support 104. Figure 4 This is a structural schematic diagram of the first positioning component 109. Figure 5 This is a schematic diagram of the upper support seat 105. This utility model provides a diversion capillary tube: including a capillary body 101, a main nozzle seat 102, and a stabilizing mechanism. The stabilizing mechanism includes a snap ring seat 103, a lower support seat 104, an upper support seat 105, a threaded cap 106, an abutment ring 107, a limiting snap ring 108, a first positioning element 109, and a second positioning element 110. The aforementioned solution can improve the stability of the connection between the capillary body 101 and the main nozzle seat 102, reducing liquid leakage. It is understood that the aforementioned solution can improve the stability of the connection between the capillary body 101 and the main nozzle seat 102.

[0025] In this embodiment, the capillary body 101 is detachably connected to the main nozzle seat 102. A quick-connect air hose connector is installed on the liquid inlet of the main nozzle seat 102 for connecting and installing the capillary body 101.

[0026] The retaining ring seat 103 is detachably mounted on the main nozzle seat 102. The lower support seat 104 is integrally provided with the abutment ring 107. The abutment ring 107 is symmetrically provided with the first positioning member 109. The first positioning member 109 is slidably inserted into the mating hole on the main nozzle seat 102. The bottom of the upper support seat 105 is provided with the second positioning member 110. The second positioning member 110 is slidably inserted into the mating hole on the lower support seat 104. The threaded cap 106 is threadedly connected to the lower support seat 104 and the upper support seat 105 respectively, and the capillary body 101 passes through the center hole of the threaded cap 106. The limiting retaining ring 108 is detachably connected to the retaining ring seat 103 and abuts against the abutment ring 107. The snap ring seat 103 is fixed by bolts, and a snap ring groove is provided in the internal cavity for the installation of the limiting snap ring 108. The lower support seat 104 and the upper support seat 105 are made of threaded cylindrical tubes. After the external thread ends are machined, they are separated into two uniform halves by wire cutting. Finally, they are processed accordingly. The first positioning member 109 is used to prevent the lower support seat 104 from rotating after installation. The second positioning member 110 is used for positioning and fitting the upper support seat 105 after installation. The threaded cap 106 is used to connect and retain the lower support seat 104 and the upper support seat 105.

[0027] Secondly, the first positioning element 109 is a cylindrical pin, which is symmetrically arranged on the abutment ring 107 during installation, and can be installed or removed by rotating it with an Allen wrench. The external thread end of the first positioning element 109 directly mates with the threaded hole on the abutment ring 107, and the cylindrical end is inserted into the positioning hole on the main nozzle seat 102.

[0028] Then, the second positioning element 110 is a positioning cylinder, which is integrally and symmetrically arranged at the bottom of the upper support 105. During installation, it can be slidably inserted into the positioning mating hole on the lower support 104.

[0029] Finally, the main nozzle holder 102 is equipped with multiple main output nozzles via a universal joint mechanism. These main output nozzles are used to spray out coolant. The main nozzle holder 102 in this application has the same structure as in the prior art, and the corresponding working components are positioned and connected in the same way.

[0030] When using this utility model to improve the stability of the connection between the capillary body 101 and the main nozzle seat 102, when connecting the capillary body 101 and the quick-connect fitting on the main nozzle seat 102, firstly, the threaded cap 106 and the lower support seat 104 are sequentially fitted onto the outside of the connecting end of the capillary body 101. Then, the end of the capillary body 101 is inserted into the quick-connect fitting on the main nozzle seat 102. Further, the lower support seat 104 is positioned by the first positioning member 109 and limited by the installation of the limiting snap ring 108. Further, the upper support seat 105 is installed by the second positioning member 110. Finally, the threaded cap 106 is installed... On the external threaded end formed after the lower support 104 and the upper support 105 are fitted together, after the capillary body 101 is connected to the quick-connect fitting on the main nozzle seat 102, a limiting structure is formed on the outside of the quick-connect fitting. This ensures that the connection between the capillary body 101 and the quick-connect fitting is always in a collinear mating position, avoiding external pulling that could cause the capillary body 101 to be pulled and tilted, resulting in uneven stress on the internal spring sheet of the quick-connect fitting, damage, or even leakage. The connection between the capillary body 101 and the main nozzle seat 102 is more stable, thereby improving the stability of the connection between the capillary body 101 and the main nozzle seat 102 and reducing liquid leakage.

[0031] Example 2:

[0032] like Figure 6 and Figure 7 As shown, where Figure 6 This is a schematic diagram of the overall structure of the shunt capillary. Figure 7 This is a schematic diagram of the structure of the mating seat 201. Based on the first embodiment, this utility model provides a diversion capillary tube, which further includes an isolation mechanism, including the mating seat 201 and a rubber ring 202.

[0033] The mating seat 201 is detachably connected to the threaded cap 106 and is located on the side of the threaded cap 106 away from the limiting snap ring 108. The rubber ring 202 is disposed in the mounting groove in the inner hole of the mating seat 201 and is slidably connected to the capillary body 101. The mating seat 201 is fixed by bolts, and the rubber ring 202 is disposed in the through hole inside the mating seat for the capillary body 101 to slide, so that the threaded cap 106 has a buffer mechanism against the outer surface of the capillary body 101 when sliding, so as to avoid damage to the capillary body 101.

[0034] In this embodiment, by providing the mating seat 201 and the rubber ring 202, a buffer mechanism is provided between the threaded cover 106 and the outer surface of the capillary body 101 when the threaded cover 106 slides, so as to avoid damage to the surface of the capillary body 101.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
