Description
Technical Field
[0001] This utility model relates to the technical field of cooling devices for machining centers, and specifically to a cooling device for a machining center. Background Technology
[0002] Machining centers evolved from CNC milling machines. The biggest difference between them and CNC milling machines is that machining centers have the ability to automatically change machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed in a single setup via an automatic tool changer, thus achieving multiple machining functions.
[0003] When a machining center mills a part using a milling cutter, a large amount of heat is generated at the contact point between the milling cutter and the part. Excessive heat can damage the surface of both the milling cutter and the part, affecting the subsequent use of the milling cutter. Therefore, it is necessary to cool the contact point between the milling cutter and the part using a cooling device. Generally, the cooling device cools the contact point by spraying water.
[0004] Since machining centers switch cutting tools during use, and different tools produce different milling effects, it is necessary to adjust the amount of water sprayed by the cooling device to avoid the water spray being too large or too small, which would affect the accuracy of the milling cutter during machining. However, existing cooling devices cannot adjust the amount of water sprayed by the nozzle, which hinders the widespread use of cooling devices in machining centers.
[0005] Therefore, it is necessary to propose a cooling device for machining centers to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a cooling device for machining centers. Through the cooperation of the internal parts of the cooling mechanism, it is convenient to cool the milling cutters and workpieces inside the machine tool. By adjusting the cooperation of the internal parts, the amount of water sprayed from the internal parts of the cooling mechanism can be adjusted. This solves the problem in the prior art that, because machining centers switch machining tools during use, and different tools have different milling effects, it is necessary to adjust the amount of water sprayed by the cooling device to avoid the milling cutter's accuracy being affected by excessive or insufficient water spray. Existing cooling devices cannot adjust the amount of water sprayed from the nozzle, which makes it difficult to promote the use of cooling devices in machining centers.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for a machining center, comprising a cooling device base, a machine tool assembly fixedly mounted on the top of the cooling device base, a cooling mechanism mounted on the top of the cooling device base and extending through the cooling device base into the interior of the machine tool assembly, and an adjustment mechanism mounted and connected on one side of the machine tool assembly, extending through the machine tool assembly into the interior of the cooling mechanism and located at one end of the cooling mechanism.
[0008] Preferably, the cooling mechanism includes a water-cooled box, which is installed and fixed at the top of the cooling device base and located on one side of the machine tool assembly. A connecting pipe is connected and fixed at the top of the water-cooled box and extends into the interior of the machine tool assembly. A water-cooling nozzle is connected and fixed at the end of the connecting pipe away from the water-cooled box and is located inside the machine tool assembly. A milling turntable is installed and fixed inside the machine tool assembly and located below the water-cooling nozzle. A scrap box is slidably connected to the side of the cooling device base away from the water-cooled box and extends into the interior of the cooling device base. A pull rod is connected and fixed to the side of the scrap box away from the cooling device base.
[0009] Preferably, the adjusting mechanism includes a connecting column, which is rotatably connected to one side of the machine tool assembly and located on one side of the connecting tube, penetrating into the interior of the machine tool assembly. A connecting end is fixedly connected to the side of the connecting column away from the machine tool assembly. Multiple scale blocks are installed and fixed on the outer wall of the machine tool assembly and distributed around the outer wall of the connecting column. A connecting ring is sleeved on the outer wall of the side of the connecting column that penetrates into the interior of the machine tool assembly and penetrates into the interior of the connecting tube. A limit block is fixedly connected to the side of the connecting column away from the connecting end and penetrates into the interior of the connecting ring. A retraction spring is fixedly connected to the side of the limit block away from the connecting ring and located inside the machine tool assembly. Multiple conveying holes are opened around the surface of the connecting ring and fit against the inner wall of the connecting tube.
[0010] Preferably, the machine tool as a whole has a collection groove inside that matches the waste box, the cooling device base has a sliding groove inside that matches the waste box, and the machine tool as a whole has a connecting groove inside that matches the connecting pipe.
[0011] Preferably, the connecting column is connected to the connecting ring via a bearing, the machine tool as a whole has an internal expansion groove that matches the limiting block, and one end of the connecting end is provided with a tapered end that matches the scale block.
[0012] Preferably, the inner wall of the connecting ring is provided with a limiting groove that matches the limiting block, the diameter of the multiple conveying holes is not the same, and sealing rings are installed on both sides of the connecting ring that contact the inner side of the connecting pipe.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] 1. By clamping and fixing the workpiece on the milling turntable, and then closing the cabinet door of the machine tool to complete the overall sealing of the machine tool, the water cooling box transports coolant to the water cooling nozzle through the connecting pipe during the milling process of the workpiece through the internal program of the machine tool. The water cooling nozzle cools the contact area between the workpiece and the milling cutter. At the same time, the waste material produced by milling flows into the waste box through the collection tank inside the cooling device base, which facilitates the collection of milling waste. The waste box can be easily moved out of the cooling device base by the pull rod, thus completing the water cooling operation of the contact area between the workpiece and the milling cutter.
[0015] 2. By pushing the connecting column, the connecting column compresses the spring through the limit block, causing the connecting column to move the limit block and move it out of the connecting ring, releasing the rotation limit on the connecting ring. Then, by rotating the connecting column, the connecting end aligns with the scale block, causing the connecting ring to rotate. After the connecting end aligns with the corresponding scale block, the connecting ring causes the corresponding sized delivery hole to fit into the connecting pipe, thus completing the adjustment of the water flow rate inside the connecting pipe.

[0027] Refer to the instruction manual appendix Figure 1-5The adjusting mechanism 3 includes a connecting column 301, which is rotatably connected to one side of the machine tool assembly 101 and located on one side of the connecting pipe 202, extending into the interior of the machine tool assembly 101.

A connecting ring 304 is sleeved on the outer wall of the connecting column 301 extending into the interior of the machine tool assembly 101, and extends through the machine tool assembly 101 to the connecting end 302. Inside the tube 202, a limiting block 305 is fixedly connected to the side of the connecting column 301 away from the connecting end 302, and passes through the machine tool assembly 101 to the inside of the connecting ring 304. A retraction spring 306 is fixedly connected to the side of the limiting block 305 away from the connecting ring 304, and is located inside the machine tool assembly 101.

[0032] Refer to the instruction manual appendix Figure 1-5 After the workpiece is clamped and fixed on the milling turntable 204 and the cabinet door of the machine tool 101 is closed to seal the machine tool 101, the water cooling box 201 transports coolant to the water cooling nozzle 203 through the connecting pipe 202 when the workpiece is being milled by the internal program of the machine tool 101.

The waste box 205 can be easily removed from the cooling device base 1 by the pull rod 206, thus completing the water cooling operation at the contact area between the workpiece and the milling cutter.
[0033] Refer to the instruction manual appendix Figure 1-5 By pushing the connecting column 301, the connecting column 301 compresses the contraction spring 306 through the limiting block 305, causing the connecting column 301 to move the limiting block 305, so that the limiting block 305 moves out of the connecting ring 304, releasing the rotation limit on the connecting ring 304.
