Abstract
Description
Technical Field
[0001] The utility model relates to the field of linear guide rail pairs, in particular to a linear guide rail pair with multiple oil storages. Background Art
[0002] Linear guide pairs are common key components in the field of precision machinery, used to achieve high-precision linear motion. The stability of their performance, motion accuracy and lifespan depend to a large extent on the lubrication of moving parts such as balls. China has authorized a utility model patent (Announcement No.: CN218625074U) to disclose a multi-oil storage linear guide pair. By setting an oil storage mechanism, the setting of the oil storage tank greatly increases the oil storage capacity and reduces the number of refueling. When the balls need to be lubricated, twist the bolt to separate it from the threaded hole, pull the pull block to remove the movable block and baffle. During the normal operation of the slider, the lubricating oil stored in the oil storage tank will enter the interior of the movable tank through the oil guide hole, completing the lubrication of the balls without affecting the normal use of the slider.
[0003] However, the above device still has some shortcomings when in use: specifically, when the ball bearings in the slider need to be lubricated, the operator needs to first unscrew all the bolts on both sides of the slider, and then pull out the baffle to allow the lubricating oil in the oil storage box to flow to the oil guide hole, thereby completing the lubrication and oiling process. This operation method is not only complicated and cumbersome, but also takes a lot of time, which reduces work efficiency. Therefore, a multi-oil storage linear guide pair is proposed to address the above situation. Utility Model Content
[0004] In order to overcome the problem that the conventional technology is complicated in operation, takes a lot of time and reduces working efficiency, the utility model proposes a linear guide pair with multiple oil reservoirs.
[0005] The utility model solves the technical problem by adopting the following technical solution: a linear guide pair with multiple oil storages, comprising a guide rail, a slider slidably fitted on the guide rail, and an oil storage box fixed on the slider.
[0006] The oil storage box has an oil storage cavity, an oil outlet hole is opened at the bottom of the oil storage box, and the oil outlet hole is communicated with the oil storage cavity; the top of the oil storage box is opened with an assembly hole, and the assembly hole is communicated with the oil storage cavity.
[0007] A pull rod is loosely fitted on the assembly hole, one end of the pull rod that penetrates into the oil storage cavity is fixedly connected to a conical plate, and a spring is sleeved on the outer wall of the pull rod.
[0008] The bottom of the conical plate is fixedly connected with a connecting rod, the bottom of the connecting rod is fixed with a plugging head, and the plugging head is matched with the oil outlet hole.
[0009] Preferably, an oil guide hole is provided on the sliding block, and the oil guide hole is connected to the oil outlet hole.
[0010] Preferably, the pull rod is fixedly connected to a handle at one end located outside the oil storage box.
[0011] Preferably, an oil filling hole communicating with the oil storage cavity is provided on the top of the oil storage box, and a rubber sealing cover is provided on the oil filling hole.
[0012] Preferably, a trapezoidal block is fixed at the middle of the bottom surface of the inner wall of the oil storage cavity, and guide blocks are fixed at both ends of the bottom surface of the inner wall of the oil storage cavity.
[0013] Preferably, the plugging head is hemispherical, made of rubber material, and has a diameter that is the same as the maximum diameter of the oil outlet.
[0014] Preferably, the oil outlet hole is conical in shape.
[0015] Preferably, a circular ring is fixed to the top of the inner wall of the oil storage chamber, the pull rod is loosely fitted with the circular ring, a rubber pad is provided on the inner wall of the circular ring, the top of the spring is in contact with the bottom of the circular ring, and the bottom of the spring is in contact with the top of the conical plate.
[0016] The utility model is beneficial in that:
[0017] 1. The utility model adopts the structural design of the pull rod, tapered plate, spring, connecting rod and plugging head. When the ball inside the slider needs to be lubricated, the plugging head is raised by lifting the pull rod, and the lubricating oil flows into the slider through the oil outlet hole to complete the lubrication of the ball. This simplifies the lubrication operation process, reduces the operation steps and time cost, and thus significantly improves work efficiency.
[0018] 2. Through the structural design of the trapezoidal block and the guide block, the utility model can make the lubricating oil in the oil storage chamber flow to the oil outlet hole faster as the lubricating oil in the oil storage chamber gradually decreases, thereby improving the oil outlet efficiency of the lubricating oil.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] The following is combined with Figure 1-6 To further explain this application,
[0029] The embodiment of the present application discloses a linear guide pair with multiple oil reservoirs. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 A linear guide pair with multiple oil storages includes a guide rail 1, a slider 2 is slidably fitted on the guide rail 1, and an oil storage box 3 is fixed on the slider 2.
[0030] There are movable grooves on both the left and right sides of the inner side of the slider 2 , and a ball bearing with one end extending into the interior of the guide rail 1 is movably installed inside the movable groove.
[0031] Furthermore, the installation method of the ball is the same as that in the comparative patent (Announcement No.: CN218625074U), and will not be elaborated here.
[0032] The oil storage box 3 has an oil storage cavity 301 , an oil outlet hole 302 is provided at the bottom of the oil storage box 3 , and the oil outlet hole 302 is communicated with the oil storage cavity 301 , and an assembly hole 303 is provided at the top of the oil storage box 3 , and the assembly hole 303 is communicated with the oil storage cavity 301 .
[0033] A pull rod 4 is loosely fitted on the assembly hole 303 , one end of the pull rod 4 that penetrates into the oil storage cavity 301 is fixedly connected to a conical plate 5 , and a spring 6 is sleeved on the outer wall of the pull rod 4 .
[0034] The bottom of the conical plate 5 is fixedly connected to a connecting rod 7 , and the bottom of the connecting rod 7 is fixed to a plugging head 701 , which is fitted on the oil outlet hole 302 .
[0035] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 An oil guide hole 201 is provided on the slider 2 , and the oil guide hole 201 is connected to the oil outlet hole 302 .
[0036] The lubricating oil may flow out through the oil outlet hole 302 and enter the oil guide hole 201 , and the lubricating oil may be transported to the balls inside the slider 2 through the oil guide hole 201 for lubrication.
[0037] The number of the oil guide holes 201 and the oil outlet holes 302 is the same and corresponds one to one.
[0038] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The pull rod 4 is fixedly connected to a handle at one end outside the oil storage box 3. The top of the oil storage box 3 is provided with an oil filling hole connected to the oil storage cavity 301, and a rubber sealing cover is provided on the oil filling hole.
[0039] Among them, by providing a handle, it is convenient for the staff to operate. After removing the rubber sealing cover, lubricating oil can be added to the oil storage chamber 301 through the oil filling hole.
[0040] Reference Figure 4 and Figure 5 A trapezoidal block 8 is fixed at the middle of the bottom surface of the inner wall of the oil storage chamber 301, and guide blocks 9 are fixed at both ends of the bottom surface of the inner wall of the oil storage chamber 301. The guide blocks 9 are triangular.
[0041] Among them, the trapezoidal block 8 and the guide block 9 can play a guiding role on the lubricating oil. As the lubricating oil in the oil storage chamber 301 gradually decreases, the lubricating oil in the oil storage chamber 301 can still flow to the oil outlet 302 faster, thereby improving the oil outlet efficiency of the lubricating oil.
[0042] Reference Figure 3、 Figure 4 、 Figure 5 and Figure 6 The plugging head 701 is hemispherical and made of rubber material. The shape of the oil outlet hole 302 is conical. The diameter of the plugging head 701 is the same as the maximum diameter of the oil outlet hole 302.
[0043] When not in use, the sealing head 701 fits in the oil outlet hole 302 and is completely in contact with the inner wall of the oil outlet hole 302 , thereby sealing the oil outlet hole 302 and preventing the lubricating oil from flowing out of the oil outlet hole 302 .
[0044] Reference Figure 5 and Figure 6 A circular ring is fixed on the top of the inner wall of the oil storage chamber 301, the center hole of the circular ring is connected to the assembly hole, the pull rod 4 is gap-fitted with the circular ring, a rubber pad is provided on the inner wall of the circular ring, the rubber pad is fitted with the outer wall of the pull rod 4, the top of the spring 6 is in conflict with the bottom of the circular ring, and the bottom of the spring 6 is in conflict with the top of the conical plate 5.
[0045] Among them, by arranging a rubber pad on the inner wall of the ring, the sealing effect can be improved, the sealing performance can be further improved, and impurities such as dust can be prevented from entering the oil storage cavity 301.
[0046] Working principle: When the ball needs to be lubricated, the staff lifts the pull rod 4 upward, and the pull rod 4 moves upward to drive the conical plate 5 to move upward. During this process, the conical plate 5 squeezes the spring 6 to cause it to deform. At the same time, the sealing head 701 rises upward and leaves the oil outlet 302, so that the lubricating oil in the oil storage chamber 301 can flow through the oil outlet 302 to the oil guide hole 201, and then flows through the oil guide hole 201 to the movable groove in the slider 2, thereby lubricating the balls in the movable groove.
[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
