Description

Technical Field

[0001] The utility model relates to the field of ball screw lubrication, in particular to a dust-proof lubrication device. Background Art

[0002] A ball screw is a transmission element most commonly used in machine tools and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial repetitive force. At the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to its very small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.

[0003] A ball screw is a commonly used linear motion component, widely used in fields such as automation equipment and robots. However, during long-term use of the ball screw, a large amount of heat and wear will be generated due to the friction between the balls and the threads, thus affecting its normal operation and service life. Therefore, it is necessary to add lubricating oil to the ball screw for lubrication treatment. However, when the ball screw is lubricated at present, it is generally installed and fixed by bolts, and then the equipment drives it to rotate to add lubricating fluid. Installing the screw by bolts requires removing each bolt one by one during disassembly, which is time-consuming and laborious and affects the working efficiency of the screw.

[0004] Therefore, it is necessary to provide a new dust-proof lubrication device to solve the above technical problems. Summary of the Utility Model

Lubricating oil is injected into the lead screw nut 6 through the oil injection hole 9 to lubricate the lead screw 5; a clamping component 4 for limiting and fixing the lead screw 5 is arranged on the outer side of the fixing component 3, and the lead screw 5 is connected and fixed to the connection disk 2 by using the clamping component 4; a sliding rod 7 is arranged on the outer side of the support frame 1. A limiting component 8 for limiting the lead screw nut 6 is arranged on the outer side of the sliding rod 7. The lead screw nut 6 is connected to the sliding rod 7 by arranging the limiting component 8 to limit the lead screw nut 6.

[0023] In the specific implementation process, such as Figure 2 and Figure 3As shown in the figure, the fixing component 3 includes a fixing sleeve 301 arranged outside the connecting plate 2. The fixing sleeve 301 is fixedly installed on the connecting plate 2. A fixing bolt 302 is arranged inside the fixing sleeve 301, and the fixing bolt 302 is threadedly connected in the fixing sleeve 301; the clamping component 4 includes a screw rod 401 clamped inside the fixing sleeve 301. The screw rod 401 is inserted into the fixing sleeve 301 and fixed by the fixing bolt 302; a connecting sleeve 402 is arranged outside the screw rod 401, and the connecting sleeve 402 is threadedly connected to the screw rod 401; a connecting column 403 is arranged outside the screw rod 401, and the connecting column 403 is fixedly installed on the screw rod 401; a groove 404 is arranged inside the connecting column 403, and the groove 404 is opened on the connecting column 403. A clamping rod 405 is rotatably connected inside the connecting sleeve 402. The clamping rod 405 is rotatably connected in the connecting sleeve 402, and one end is clamped in the groove 404. By rotating the connecting sleeve 402 outside the screw rod 401 to drive the connecting column 403 to move leftward, the connecting column 403 drives the groove 404 to move leftward. During the leftward movement of the groove 404, one end of the clamping rod 405 clamped in the groove 404 is pressed down, driving the clamping rod 405 to rotate, and the other end contracts inward, clamping the lead screw 5 inside. When disassembling the lead screw, just rotate the connecting sleeve 402 in the reverse direction.

[0024] An anti-slip rubber strip 12 is arranged outside the clamping rod 405. The anti-slip rubber strip 12 is fixed on the clamping rod 405. By means of the anti-slip rubber strip 12, the friction between the clamping rod 405 and the lead screw 5 is increased, thereby improving the clamping firmness of the lead screw 5.

[0025] Two connecting plates 2 are symmetrically arranged, and a connecting rod 11 is arranged outside the right connecting plate 2. The connecting plate 2 is rotatably installed on the support frame 1. The connecting rod 11 passes through the right support frame 1 and is fixedly installed on the connecting plate 2.

A fastening bolt 803 is arranged inside the clamping pieces 802. The left end of the fastening bolt 803 is inserted into the left clamping piece 802, and the right end is threadedly connected to the right clamping piece 802. By rotating the fastening bolt 803, the two clamping pieces 802 are brought closer to clamp the lead screw nut 6. When the lead screw nut 6 moves, it drives the sliding sleeve 801 to move synchronously outside the sliding rod 7, performing a limiting process on the lead screw nut 6.

[0028] When lubricating the lead screw 5, first install the lead screw 5 on the connecting plate 2. During installation, insert the screw rod 401 into the fixed sleeve 301, and then use the fixing bolt 302 to fix the screw rod 401 in the fixed sleeve 301. Then, respectively clamp both ends of the lead screw 5 in the connecting sleeves 402 at both ends. By rotating the connecting sleeve 402 on the outside of the screw rod 401, drive the connecting column 403 to move leftward. The connecting column 403 drives the groove 404 to move leftward. During the leftward movement of the groove 404, press down one end of the clamping rod 405 clamped in the groove 404, drive the clamping rod 405 to rotate, and the other end moves inward to tighten, clamping the lead screw 5 inside.

The connecting rod 11 passes through the support frame 1 on the right side and is fixedly installed on the connecting plate 2. Connect the connecting rod 11 to the transmission device, which can drive the connecting plate 2 to rotate. The connecting plate 2 drives the lead screw 5 to rotate synchronously. The lead screw 5 drives the lead screw nut 6 to move on its outside. Inject lubricating oil into the lead screw nut 6 through the oil injection hole 9 to lubricate the lead screw 5. The sealing ring 10 in the lead screw nut 6 can play a role in dust prevention.
