Technical Field

[0001] This utility model specifically relates to a spindle support device for CNC machining centers with automatic lubrication function, belonging to the technical field of CNC machining centers. Background Technology

[0002] The CNC machine tool spindle is the core component that drives the rotation of the workpiece or tool. It consists of a spindle, bearings, and transmission components, and is widely used in rotary machine tools such as lathes and milling machines. Its performance indicators mainly include rotational accuracy, dynamic / static stiffness, and speed adaptability. The spindle component achieves high-speed operation through bearing technology. Early spindles used sliding bearings, and later developed rolling bearings, hydrostatic bearings, etc. After the 1970s, electric spindles integrated the motor and spindle, incorporating composite ceramic bearings, oil-air lubrication, and circulating cooling technology. The speed can reach tens of thousands of revolutions per minute, and they are equipped with encoders and automatic tool changers.

[0003] In CNC machining centers, the spindle is a critical component, and the stability and lubrication of its support system directly affect machining accuracy and efficiency. Traditional spindle support systems often rely on manual, periodic lubrication. This method is not only cumbersome but also makes it difficult to ensure timely and even lubrication, which can easily lead to accelerated spindle wear and affect machining quality.

[0004] To address this, a spindle support device for CNC machining centers with automatic lubrication function is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a CNC machining center spindle support device with automatic lubrication function, which lubricates and supports the spindle simultaneously.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a CNC machining center spindle support device with automatic lubrication function, comprising: a spindle body, a support base, a mounting sleeve, and a mounting crossbar. The mounting sleeve consists of two semi-annular structures that can be installed on each other. The support base is fixedly installed at the bottom of the mounting sleeve. An oil injection pipe extending into the interior of the mounting sleeve is fixedly installed at the top of the mounting sleeve. A flow equalization pipe is fixedly installed at the bottom of the oil injection pipe. A nozzle is provided at the bottom of the flow equalization pipe. A cotton plate corresponding to the nozzle is provided inside the mounting sleeve. A filter screen is slidably installed inside the mounting sleeve. A brush plate extending into the mounting sleeve is fixedly installed at the top of the filter screen. Two sets of flipping plates are movably installed inside the mounting sleeve. A spring is movably connected between the two sets of flipping plates. A mounting bracket is movably installed at the top of each of the two support bases. A push plate is threaded inside the mounting bracket. A mounting crossbar is movably installed between the mounting brackets. The mounting crossbar is located on the outside of the two mounting sleeves.

[0007] Preferably, each of the two mounting sleeves has a mounting block fixedly mounted on its top, and the two mounting blocks are connected by a threaded bolt.

[0008] Preferably, the filter screen is slidably installed inside the mounting sleeve via a movable rod, the mounting sleeve is movably installed between the flip plate and the mounting base, and the top of the flip plate is rotatably mounted with a squeezing roller that cooperates with the bottom of the filter screen.

[0009] Preferably, the support base and the mounting frame are movably mounted via a rotating seat, and the mounting frame has a threaded rod installed on its internal threads.

[0010] Preferably, one end of the threaded rod is rotatably mounted to the push plate via a bearing, and a threaded sleeve that mates with the threaded rod is fixedly mounted on the mounting bracket.

[0011] Preferably, the mounting bracket is provided with a sliding groove that cooperates with the push plate, and the outer side of the mounting sleeve is provided with a limiting groove corresponding to the mounting crossbar.

[0012] Preferably, the two mounting brackets are provided with a docking block and a docking groove on their adjacent sides, and the docking block and the docking groove are connected and cooperate with each other.

[0013] The beneficial effects of this utility model are:

[0014] I. A CNC machining center spindle support device with automatic lubrication function, after being installed by two mounting sleeves, injects lubricating oil into the flow equalization pipe through an oil injection pipe. The nozzle at the bottom of the flow equalization pipe can distribute the lubricating oil onto the cotton plate, which then penetrates to the inside of the mounting sleeve. Rotating the spindle body allows lubricating oil to adhere to it. During rotation, the outside of the spindle body rubs against the surface of the brush plate, making the lubricating oil more even. The cavity at the bottom of the mounting sleeve can filter and collect excess lubricating oil through a filter screen. The tension of the spring causes the two flipping plates to press against each other, squeezing the bottom of the filter screen, allowing the filter screen to slide along the outside of the movable rod, and ensuring that the top of the brush plate fits tightly against the outside of the spindle body.

[0015] II. This CNC machining center spindle support device with automatic lubrication function, during the process of the support base and the mounting sleeve merging together, the two mounting frames are connected through the docking block and the docking groove. At the same time, the mounting block set on the top of the mounting sleeve is limited by the threaded bolt, and the mounting crossbar is installed on the outside of the mounting sleeve. At the same time, the mounting frame is flipped and installed on the outer end of the mounting crossbar. By rotating the threaded rod, the push plate slides along the inside of the sliding groove, so that the push plate can be used to squeeze the mounting crossbar, so that the mounting crossbar is installed into the inside of the limiting groove, and the two mounting sleeves are limited.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 6As shown, a CNC machining center spindle support device with automatic lubrication function includes: a spindle body 1, a support base 101, a mounting sleeve 102, and a mounting crossbar 3. The mounting sleeve 102 consists of two semi-annular structures that can be installed on each other. The support base 101 is fixedly installed at the bottom of the mounting sleeve 102. An oil injection pipe 105 extending into the interior of the mounting sleeve 102 is fixedly installed at the top of the mounting sleeve 102. A flow equalization pipe 2 is fixedly installed at the bottom of the oil injection pipe 105. A nozzle 201 is provided at the bottom of the flow equalization pipe 2. A cotton plate 202 corresponding to the nozzle 201 is provided inside the mounting sleeve 102. A filter is slidably installed inside the mounting sleeve 102. The top of the screen 204 is fixedly mounted with a brush plate 205 extending to the mounting sleeve 102. Inside the mounting sleeve 102, two sets of flip plates 207 are movably mounted. A spring 208 is movably connected between the two sets of flip plates 207. The top of each of the two support seats 101 is movably mounted with a mounting bracket 302. A push plate 306 is threaded inside the mounting bracket 302. A mounting crossbar 3 is movably mounted between the mounting brackets 302. The mounting crossbar 3 is located on the outside of the two mounting sleeves 102. The top of each of the two mounting sleeves 102 is fixedly mounted with a mounting block 103. The two mounting blocks 103 are limited and mounted by a threaded bolt 104.

[0025] After the two mounting sleeves 102 are installed together, lubricating oil is injected into the interior of the flow equalization pipe 2 through the oil injection pipe 105. The nozzle 201 at the bottom of the flow equalization pipe 2 can distribute the lubricating oil on the cotton plate 202. The lubricating oil penetrates into the inner side of the mounting sleeve 102 through the cotton plate 202. By rotating the main shaft body 1, lubricating oil can be adhered to the main shaft body 1. During the rotation, the outside of the main shaft body 1 is wiped with the surface of the brush plate 205, so that the lubricating oil can be more evenly distributed. The cavity at the bottom of the mounting sleeve 102 can filter the excess lubricating oil through the filter screen 204 and collect it.

[0026] Reference Figure 2 - Figure 5 The filter screen 204 is slidably installed inside the mounting sleeve 102 via the movable rod 203. The mounting sleeve 102 is movably installed between the flip plate 207 and the mounting base 206. The top of the flip plate 207 is rotatably installed with a squeezing roller 209 that mates with the bottom of the filter screen 204. The support base 101 is movably installed between the mounting frame 302 and the mounting bracket 302 via the rotating base 303. The mounting bracket 302 has a threaded rod 304 threaded inside.

[0027] The tension of the spring 208 causes the two flip plates 207 to press against each other, pressing the bottom of the filter screen 204, allowing the filter screen 204 to slide along the outside of the movable rod 203, and allowing the top of the brush plate 205 to fit tightly against the outside of the main shaft body 1.

[0028] Reference Figure 5 - Figure 6 One end of the threaded rod 304 is rotatably mounted to the push plate 306 via a bearing. A threaded sleeve 305 that mates with the threaded rod 304 is fixedly mounted on the mounting bracket 302. A sliding groove 307 that mates with the push plate 306 is provided on the mounting bracket 302. A limiting groove 301 corresponding to the mounting crossbar 3 is provided on the outer side of the mounting sleeve 102. A docking block 308 and a docking groove 309 are respectively provided on the adjacent side of the two mounting brackets 302. The docking block 308 and the docking groove 309 are docked and mated together.

[0029] During the process of merging the support base 101 and the mounting sleeve 102, the two mounting brackets 302 are connected through the docking block 308 and the docking groove 309. At the same time, the mounting block 103 set on the top of the mounting sleeve 102 is limited by the threaded bolt 104, and the horizontal bar 3 is installed on the outside of the mounting sleeve 102. At the same time, the mounting bracket 302 is flipped and installed on the outer end of the horizontal bar 3.

[0030] The implementation principle of this utility model of a CNC machining center spindle support device with automatic lubrication function is as follows: During use, two support seats 101 and mounting sleeves 102 are joined together. Two mounting frames 302 are connected via a mating block 308 and a mating groove 309. Simultaneously, the mounting block 103 on the top of the mounting sleeve 102 is limited by a threaded bolt 104. A horizontal bar 3 is mounted on the outer side of the mounting sleeve 102. The mounting frame 302 is then flipped to install the outer end of the horizontal bar 3. Rotating the threaded rod 304 causes the push plate 306 to slide along the sliding groove 307, thus facilitating the pressing of the horizontal bar 3 by the push plate 306, allowing it to be installed into the limiting groove 301. This limits the two mounting sleeves 102. After the two mounting sleeves 102 are installed together... Lubricating oil is injected into the flow equalization pipe 2 through the oil injection pipe 105. The nozzle 201 at the bottom of the flow equalization pipe 2 distributes the lubricating oil onto the cotton plate 202. The lubricating oil penetrates into the inner side of the mounting sleeve 102 through the cotton plate 202. By rotating the main shaft body 1, lubricating oil adheres to the main shaft body 1. During the rotation, the outer side of the main shaft body 1 rubs against the surface of the brush plate 205, making the lubricating oil more even. The cavity at the bottom of the mounting sleeve 102 allows excess lubricating oil to be filtered and collected through the filter screen 204. The tension of the spring 208 causes the two flipping plates 207 to press against each other, pressing the bottom of the filter screen 204, allowing the filter screen 204 to slide along the outer side of the movable rod 203, so that the top of the brush plate 205 can fit tightly against the outer side of the main shaft body 1.
