Description

Technical Field

[0001] The utility model belongs to the technical field of spindle lubrication, and particularly relates to a rotary guide spindle lubrication device. Background Art

[0002] During the use of the spindle, in order to extend the practical life of the spindle, a lubrication device is needed to lubricate the spindle to provide long-term protection.

[0003] After searching, in the prior art, Chinese patent application number: CN202322185622.3 discloses a spindle lubrication device for cutting in a gantry machining center. The spindle lubrication device for cutting in a gantry machining center can spray the lubricating oil in the oil storage tank onto the surface of the spindle through the oil spray plate to lubricate the spindle by setting an oil storage tank, a sealing plate, a weight sensor, an alarm light, an oil pump, a valve and an oil spray plate. At the same time, the weight of the lubricating oil is monitored by the weight sensor. When the amount of the lubricating oil gradually decreases, the alarm light flashes so that the lubricating oil can be added in time to make the lubricating device continuous when in use. By setting a dust suction pump, a connecting pipe and a collecting box for coordinated use, the dust attached to the surface of the spindle can be adsorbed by the dust suction pump and the connecting pipe and then the lubricating oil can be sprayed again to improve the lubrication effect on the spindle. At the same time, the collecting box can collect the fallen lubricating oil to improve the oil saving of the lubricating device when in use.

[0004] However, the device still has the following defects:

[0005] The device sprays lubricating oil onto the surface of the spindle through the oil spray plate. Since the lubricating oil sprayed onto the spindle will collide with the spindle, the lubricating oil is likely to splash and splash to the outside of the collection box, which is likely to cause waste of lubricating oil.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a rotary guide spindle lubrication device. It includes a base plate 110, a mounting frame 120 is mounted on the base plate 110, a recovery box 130 is mounted on the mounting frame 120, a fixing component for fixing the spindle is mounted on the mounting frame 120, a lubrication component for lubricating the spindle is mounted on the mounting frame 120, an adjustment component for adjusting the position of the lubrication component is mounted on the mounting frame 120, and a dust removal component for dust removal on the spindle is mounted on the adjustment component;

[0028] The lubrication assembly includes two groups of spray tanks 370, and the two groups of spray tanks 370 are installed in the mounting frame 120. Limit blocks 371 are installed on opposite sides of the two groups of spray tanks 370. One side of the two groups of limit blocks 371 is an arc-shaped structure. A brush plate 373 is installed on one side of the two groups of limit blocks 371. One side of the two groups of limit blocks 371 is provided with an oil outlet hole 372, and the two groups of oil outlet holes 372 are respectively connected to the two groups of spray tanks 370. A third transmission pipe 374 is installed in the two groups of spray tanks 370, and multiple groups of nozzles 375 are installed on the two groups of third transmission pipes 374. The multiple groups of nozzles 375 are located in the oil outlet hole 372.

[0029] When lubricating the spindle, the lubricating oil is sprayed onto the spindle through the nozzle 375 on the third transmission pipe 374. Due to the fit between the stop block 371 and the spindle, the stop block 371 limits the splashing lubricating oil, so that the lubricating oil is not easy to splash outside the recovery box 130. At the same time, the brush plate 373 on the stop block 371 smears the lubricating oil on the spindle so that the lubricating oil can be evenly attached to the spindle. The arc-shaped setting of the stop block 371 allows the stop block 371 to fit on the spindle.

[0030] The lubrication assembly also includes an oil storage tank 310, which is installed on the upper side wall of the mounting frame 120. An oil inlet pipe 311 and an oil pump 320 are installed on the oil storage tank 310. A first transmission pipe 330 is installed on the output end of the oil pump 320. A connecting pipe 340 is installed at one end of the first transmission pipe 330. The connecting pipe 340 is installed on the top of the mounting frame 120. Two groups of second transmission pipes 350 are installed on the connecting pipe 340. One ends of the two groups of second transmission pipes 350 pass through the mounting frame 120, and one ends of the two groups of second transmission pipes 350 are installed with bellows 360, and one ends of the two groups of bellows 360 are respectively installed on two groups of third transmission pipes 374.

[0031] When lubricating the main shaft, the oil pump 320 transfers the lubricating oil in the oil storage tank 310 to the connecting pipe 340 through the first transmission pipe 330, and the connecting pipe 340 transfers the lubricating oil to the two groups of spray tanks 370 through the two groups of second transmission pipes 350 and the bellows 360, respectively, so that the two groups of spray tanks 370 can lubricate the main shaft at the same time. The setting of the bellows 360 allows the lubricating oil to be continuously transferred to the spray tank 370 during the movement of the spray tank 370, so that the spray tank 370 can continuously lubricate the main shaft.

[0032] The fixing assembly includes a first motor 210, which is mounted on the top of the mounting frame 120. The output end of the first motor 210 passes through the mounting frame 120, and the output end of the first motor 210 is transmission-connected with a rotating rod 220, and an electromagnet 230 is installed at one end of the rotating rod 220.

[0033] When lubricating the spindle, the electromagnet 230 is energized to adsorb and fix the spindle, so that the lubricating device can fix and lubricate spindles of different sizes, thereby improving the flexibility of the lubricating device. The first motor 210 electrically rotates the rotating rod 220, so that the rotating rod 220 drives the electromagnet 230 to rotate, so that the spindle rotates, so that the spindle rotates in the limit block 371, so that the nozzle 375 can lubricate the entire spindle.

[0034] The adjustment assembly includes a mounting block 410, which is mounted on a mounting frame 120. A cylinder 420 is mounted on the mounting block 410. The output end of the cylinder 420 passes through the mounting block 410, and a moving block 440 is mounted on the output end of the cylinder 420. Two groups of guide rods 430 are mounted on the moving block 440, and both groups of guide rods 430 are slidably connected to the mounting block 410. A moving groove 510 is provided on the moving block 440, and a bidirectional threaded rod 520 is rotatably connected in the moving groove 510. Two groups of connecting blocks 540 are threadedly connected to the bidirectional threaded rod 520, and the two groups of connecting blocks 540 are respectively mounted on two groups of injection tanks 370. A second motor 530 is mounted on one end of the moving block 440, and the output end of the second motor 530 passes through the moving groove 510, and the output end of the second motor 530 is transmission-connected to one end of the bidirectional threaded rod 520.

[0035] During the lubrication of the spindle, the cylinder 420 drives the moving block 440 to move vertically, so that the moving block 440 drives the two sets of spray boxes 370 to move vertically, so that the spray boxes 370 can move vertically on the spindle, thereby lubricating the entire spindle, and lubrication of the spindle is not easily missed. The second motor 530 drives the bidirectional threaded rod 520 to rotate, so that the bidirectional threaded rod 520 drives the two sets of connecting blocks 540 to move, so that the two sets of spray boxes 370 are close to and away from each other, so that the two sets of spray boxes 370 can fit and lubricate spindles of different sizes.

[0036] The dust removal assembly includes a dust suction pump 610 , which is mounted on the moving block 440 , and a suction pipe 620 is mounted on the dust suction pump 610 .

[0037] Before lubricating the spindle, the dust suction pump 610 absorbs the dust on the spindle through the suction tube 620, and moves vertically under the action of the moving block 440, and drives the spindle to rotate through the first motor 210, so that the suction tube 620 can remove dust from the entire spindle, thereby preventing dust from affecting the lubrication of the spindle.

[0038] Specifically, the internal electrical connection structure of the first motor 210, the second motor 530, the cylinder 420, the oil pump 320 and the dust suction pump 610 is well known to those skilled in the art and will not be described in detail herein. The electrical components in this application are all connected to an external power source when in use.

[0039] The circuits, electrical components and modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to the software.

[0040] The control method of the present application document is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field, which is common knowledge in this field. In addition, the present application document is mainly used to protect mechanical devices, so the present application document will no longer explain the control method and circuit connection in detail.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
