Description

Technical Field

[0001] This application belongs to the field of drilling technology, and particularly relates to a cooling device for a radial drilling machine. Background Technology

[0002] A radial drilling machine, also known as a radial drill, is a hole-making machine that can be used for various machining operations such as drilling, reaming, boring, tapping, and end-face finishing. A radial drilling machine consists of a base, a radial arm that rotates and moves up and down around a column on the base, a spindle head that moves horizontally on the radial arm, and a drill rod mounted on the spindle. Radial drilling machines are easy and flexible to operate, have a wide range of applications, and are particularly suitable for machining holes in large parts with multiple holes, whether in single-piece or batch production. They are common machine tools in general machining workshops.

[0003] During the production process, both the cutting tools and the workpieces are prone to high temperatures. Existing cooling methods usually involve spraying coolant directly onto the machining area. However, a large amount of coolant is often required to achieve effective cooling during drilling. Therefore, this issue needs to be addressed. Utility Model Content

[0004] The purpose of this application is to address the aforementioned technical problems by providing a cooling device for a radial drilling machine that improves the cooling efficiency of the coolant.

[0005] This application provides a cooling device for a radial drilling machine, including a radial drilling machine body and a spindle box disposed on the radial drilling machine body, wherein the radial drilling machine body includes:

[0006] The liquid storage tank is placed on the spindle box;

[0007] The first cooling pipe is connected to the liquid storage tank;

[0008] The vortex tube includes a first connection port, a second connection port, and a third connection port. The first connection port is connected to an air source, the second connection port ejects cold air, and the third connection port ejects hot air.

[0009] The second cooling pipe is connected to the second connection port;

[0010] The nozzle assembly includes an inner nozzle body and an outer nozzle body. The inner nozzle body is connected to a second cooling pipe, and the outer nozzle body is connected to a first cooling pipe. The inner nozzle body and the outer nozzle body are installed and connected together, and a flow channel is provided between the inner nozzle body and the outer nozzle body.

[0011] The reservoir stores coolant, which provides cooling and lubrication to the cutting tool and workpiece during drilling. The first cooling pipe, made of universal bamboo tube or flexible hose, delivers coolant to the nozzle assembly. The vortex tube connects to an air source through the first connection port. After the air source enters the vortex tube, cool air is ejected from the second connection port, and hot air is ejected from the third connection port. The second connection port connects to the second cooling pipe, which also uses universal bamboo tube or flexible hose. The second cooling pipe delivers cold air to the nozzle assembly. The cold air mixes with the coolant and acts simultaneously on the drilling location, improving cooling efficiency, reducing coolant consumption, and ensuring cooling effect. In the nozzle assembly, the second cooling pipe connects to the inner nozzle body, through which cold air is ejected. The first cooling pipe connects to the outer nozzle body, connecting it to the flow channel. The coolant and cold air mix at the nozzle opening of the outer nozzle body, further enhancing the cooling effect of the coolant.

[0012] Furthermore, the nozzle assembly includes:

[0013] The first insertion hole is located on the inner nozzle body and is adapted to the second cooling pipe;

[0014] The second insertion hole is located on the outer nozzle body and is adapted to the first cooling pipe.

[0015] Furthermore, the nozzle assembly includes:

[0016] The seal is placed between the inner and outer nozzle bodies.

[0017] Furthermore, the liquid storage tank includes:

[0018] The first piston body is placed inside the liquid storage tank;

[0019] The drive mechanism is connected to the first piston body.

[0020] Furthermore, the drive mechanism includes:

[0021] The drive cavity is connected to the third connection port;

[0022] The second piston body is placed inside the drive chamber;

[0023] The connecting rod is positioned between the second piston body and the first piston body.

[0024] Furthermore, the drive mechanism also includes:

[0025] The pressure relief valve is located on the drive chamber.

[0026] Furthermore, the liquid storage tank includes:

[0027] The filter element is installed in the liquid storage tank and corresponds to the first cooling pipe.

[0028] Furthermore, it also includes:

[0029] The movable bracket is movably installed between the liquid storage tank and the spindle box.

[0030] The beneficial effects of this application are:

[0031] 1. Cold air and coolant are mixed and sprayed out through the nozzle assembly. The cold air and coolant then act simultaneously on the drilling location, improving cooling efficiency, thereby reducing the amount of coolant used while ensuring the cooling effect.

[0032] 2. Cold air is ejected through the inner nozzle, and coolant flows through the flow channel, where the coolant and cold air are mixed at the nozzle opening of the outer nozzle.

[0033] 3. The first piston body is moved by the drive mechanism to provide pressure for the coolant in the reservoir to be discharged outward. Attached Figure Description

[0041] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.

[0042] Example 1:

[0043] like Figures 1-4 As shown, this application embodiment provides a cooling device for a radial drilling machine, including a radial drilling machine body 100 and a spindle box 110 disposed on the radial drilling machine body 100. The radial drilling machine body 100 includes:

[0044] The liquid storage tank 200 is placed on the spindle box 110;

[0045] The first cooling pipe 210 is connected to the liquid storage tank 200;

[0046] The vortex tube 300 includes a first connection port 310, a second connection port 320, and a third connection port 330. The first connection port 310 is connected to an air source, the second connection port 320 ejects cold air, and the third connection port 330 ejects hot air.

[0047] The second cooling pipe 400 is connected to the second connector 320;

[0048] The nozzle assembly 500 includes an inner nozzle body 510 and an outer nozzle body 520. The inner nozzle body 510 is connected to a second cooling pipe 400, and the outer nozzle body 520 is connected to a first cooling pipe 210. The inner nozzle body 510 and the outer nozzle body 520 are installed and connected together, and a flow channel 530 is provided between the inner nozzle body 510 and the outer nozzle body 520.

[0049] The coolant is stored in the reservoir 200 and is used to cool and lubricate the cutting tool and workpiece during drilling. The first cooling pipe 210, which is made of a universal bamboo tube or a flexible hose, is used to deliver the coolant to the nozzle assembly 500. The vortex tube 300 is connected to an air source through the first connection port 310. After the air source is introduced into the vortex tube 300, coolant is sprayed out from the second connection port 320 and hot air is sprayed out from the third connection port 330. The second connection port 320 is connected to the second cooling pipe 400, which is also made of a universal bamboo tube or a flexible hose. Pipes and other fittings are connected to the nozzle assembly 500 through the second cooling pipe 400. The cold air is transported to the nozzle assembly 500 by mixing with the coolant. The cold air and coolant act simultaneously on the drilling position, which improves the cooling efficiency, thereby reducing the amount of coolant used and ensuring the cooling effect. The second cooling pipe 400 in the nozzle assembly 500 is connected to the inner nozzle body 510. The cold air is sprayed out through the inner nozzle body 510. The first cooling pipe 210 is connected to the outer nozzle body 520, so that the first cooling pipe 210 is connected to the flow channel 530. The coolant and cold air are mixed at the nozzle opening of the outer nozzle body 520 to improve the cooling effect of the coolant.

[0050] The inner nozzle body 510 and the outer nozzle body 520 are connected by threaded installation or by fasteners such as bolts. There is a valve body between the first cooling pipe 210 and the liquid storage tank 200 to control the opening and closing of the connection between the first cooling pipe 210 and the liquid storage tank 200.

[0051] Example 2:

[0052] like Figures 1-3 As shown, this application embodiment provides a cooling device for a radial drilling machine. In addition to the above-mentioned technical features, the nozzle assembly 500 further includes:

[0053] The first insertion hole 511 is placed on the inner nozzle body 510 and is adapted to the second cooling pipe 400.

[0054] The second insertion hole 521 is placed on the outer nozzle body 520 and is adapted to the first cooling pipe 210.

[0055] The first insertion hole 511 facilitates the insertion and connection of the second cooling pipe 400 and the inner nozzle body 510, and the second insertion hole 521 facilitates the insertion and connection of the first cooling pipe 210 and the outer nozzle body 520. The axes between the first insertion hole 511 and the second insertion hole 521 are parallel or perpendicular to each other. If the axes between the first insertion hole 511 and the second insertion hole 521 are parallel, the first insertion hole 511 and the second insertion hole 521 are located at the same end of the nozzle assembly 500. If the axes between the first insertion hole 511 and the second insertion hole 521 are perpendicular to each other, the second insertion hole 521 is placed on the outer wall surface of the outer nozzle body 520.

[0056] Furthermore, the nozzle assembly 500 includes:

[0057] The seal 540 is placed between the inner nozzle body 510 and the outer nozzle body 520.

[0058] The sealing performance between the inner nozzle body 510 and the outer nozzle body 520 is improved by the seal 540, so that when the coolant flows in the flow channel 530, it is not easy to leak from the connection between the inner nozzle body 510 and the outer nozzle body 520, thereby improving the practical stability of the nozzle assembly 500.

[0059] Example 3:

[0060] like Figure 2 , Figure 4 As shown, this application embodiment provides a cooling device for a radial drilling machine. In addition to the above-mentioned technical features, the liquid storage tank 200 further includes:

[0061] The first piston body 220 is placed inside the liquid storage tank 200;

[0062] The drive mechanism 600 is connected to the first piston body 220.

[0063] The first piston body 220 is movably placed inside the liquid storage tank 200. The first piston body 220 is adapted to the inner wall surface of the liquid storage tank 200. The first piston body 220 is pushed to move by the drive mechanism 600 to provide pressure for the coolant in the liquid storage tank 200 to be discharged outward. The drive mechanism 600 is installed on the liquid storage tank 200 or the spindle box 110. The drive mechanism 600 provided in this application is installed on the spindle box 110.

[0064] Furthermore, the drive mechanism 600 includes:

[0065] The drive cavity 610 is connected to the third connection port 330;

[0066] The second piston body 620 is placed inside the drive chamber 610;

[0067] The connecting rod 630 is positioned between the second piston body 620 and the first piston body 220.

[0068] The second piston body 620 is installed in the drive chamber 610. The drive chamber 610 is connected to the third connection port 330 by a pipe. Hot air generated through the third connection port 330 is introduced into the drive chamber 610 to provide pressure to push the second piston body 620 to move. The drive chamber 610 isolates it from the liquid storage tank 200, so that the heat of the hot air introduced into the drive chamber 610 is not easily transferred to the coolant in the liquid storage tank. The connecting rod 630 is connected to the first piston body 220 and the second piston body 620 by bolts or other fasteners. The second piston body 620, the connecting rod 630, and the first piston body 220 are driven to move by the hot air generated by the third connection port 330. This reduces the installation of one power source and improves the utilization rate of energy resources.

[0069] Furthermore, the drive mechanism 600 also includes:

[0070] The pressure relief valve 640 is located on the drive chamber 610.

[0071] The pressure in the drive chamber 610 is controlled by the pressure relief valve 640, so that the movement of the second piston body 620 has appropriate stability, and the flow rate stability of the coolant is further guaranteed.

[0072] Furthermore, the liquid storage tank 200 includes:

[0073] The filter element 230 is installed in the liquid storage tank 200 and corresponds to the first cooling pipe 210.

[0074] The filter element 230 is a filter screen or filter element, etc. The filter element 230 is installed at the connection between the corresponding liquid storage tank 200 and the first cooling pipe 210, and the coolant passing through is filtered by the filter element 230.

[0075] Example 4:

[0076] like Figure 1 , Figure 2 As shown, this application embodiment provides a cooling device for a radial drilling machine, which, in addition to the above-mentioned technical features, further includes:

[0077] The movable bracket 700 is movably installed between the liquid storage tank 200 and the spindle box 110.

[0078] The movable bracket 700 is installed between the liquid storage tank 200 and the spindle box 110. The movable bracket 700 is driven by a cylinder connected to an air source or a hydraulic cylinder connected to a hydraulic source, or by a motor, screw structure, or other driving power connected to a power source. The movable bracket 700 controls the movement of the liquid storage tank 200, so that the liquid storage tank 200 can be separated from the first piston body 220, which facilitates the addition of coolant to the liquid storage tank 200. Even if the drive mechanism 600 is not used to drive the first piston body 220, the movable bracket 700 can still move to realize the relative movement between the liquid storage tank 200 and the first piston body 220.

[0079] The vortex tube 300 is mounted on the movable bracket 700 by bolts or other fasteners.
