Technical Field

[0001] This utility model belongs to the technical field of ball screw modules, specifically referring to a ball screw module that is easy to maintain quickly. Background Technology

[0002] A ball screw module is a high-precision, high-rigidity linear motion mechanism, mainly composed of a ball screw, linear guide, motor, etc. Its core component, the ball screw, is a transmission element that can convert rotary motion into linear motion or reverse motion.

[0003] However, most of the existing ball screw modules have the balls directly embedded in the grooves for rotation. Since it is inconvenient to apply oil for maintenance inside the balls and they do not have an oil storage structure, they need to be frequently lubricated. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model proposes a ball screw module that is easy to maintain quickly, which effectively solves the problem that it is inconvenient to apply oil for maintenance inside the ball screw module and that frequent application of lubricating oil is required.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a ball screw module that is easy to maintain quickly, including a guide rail body, a ball maintenance structure provided on the guide rail body, and a driving structure provided on the guide rail body, the driving structure driving the ball maintenance structure to move.

[0006] Preferably, the ball bearing maintenance structure includes a dovetail groove in the middle of the guide rail body, a sliding seat slidably disposed within the dovetail groove, a first track on the upper left and right sides of the guide rail body parallel to the dovetail groove, a ball bearing groove below the sliding seat containing a first ball bearing, an oil reservoir within the sliding seat, a rubber plug inserted into an oil filling hole above the oil reservoir, a second track on the guide rail body on the lower left and right sides of the dovetail groove, a second ball bearing groove on the lower left and right sides of the sliding seat containing a second ball bearing, an oil passage within the sliding seat communicating with the second ball bearing groove, an oil reservoir within the sliding seat communicating with the oil passage via an oil pipe, and a rubber plug inserted into an oil filling hole above the second oil reservoir.

[0007] To achieve a better driving effect, the driving structure includes a motor fixedly mounted on one end of the guide rail body, and a threaded rod fixedly mounted on the output shaft of the motor, with one end of the threaded rod threaded through the sliding seat and rotatably mounted on the other end of the guide rail body.

[0008] To achieve high-precision movement more quickly, the first ball is arranged to roll linearly within the first track, and the second ball is arranged to roll linearly within the second track.

[0009] Furthermore, the oil storage tank is provided with an oil pipe connected to a ball bearing groove at the bottom and an oil injection hole at the top.

[0010] To facilitate maintenance, the second rubber stopper can store lubricating oil for six sets of ball bearings, while the first oil reservoir stores lubricating oil for a single set of ball bearings.

[0011] The beneficial effects of this utility model using the above structure are as follows: The ball screw module proposed in this solution is easy to maintain quickly. By setting up oil storage tank 1 and oil storage tank 2 separately, lubricating oil can be added quickly and stored, thereby achieving quick maintenance and reducing the number of maintenance times.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 and Figure 3 As shown, the present invention proposes a ball screw module that is easy to maintain quickly, including a guide rail body 1, a ball maintenance structure 2 provided on the guide rail body 1, and a drive structure 3 provided on the guide rail body 1, the drive structure 3 driving the ball maintenance structure 2 to move.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ball bearing maintenance structure 2 includes a dovetail groove 4 formed in the middle of the guide rail body 1. A sliding seat 5 is slidably positioned within the dovetail groove 4. Tracks 6 are provided on the left and right sides above the guide rail body 1 and are parallel to the dovetail groove 4. A ball bearing groove 7 is formed below the sliding seat 5, and balls 8 roll within the ball bearing groove 7. The balls 8 roll linearly within the track 6. An oil reservoir 9 is formed within the sliding seat 5. An oil pipe is provided below the oil reservoir 9 and connects to the ball bearing groove 7, and an oil filling hole is provided above the oil reservoir 9. The oil reservoir 9 stores lubricating oil for use by a single set of balls 8. An oil filling hole is provided above the oil reservoir 9. The rubber plug 10 is inserted and removed. The guide rail body 1 on the left and right sides of the bottom of the dovetail groove 4 is provided with a second track 11. The ball groove 12 is provided on the left and right sides below the sliding seat 5. The ball 13 rolls in the ball groove 12 and rolls linearly in the track 11. The oil passage 14 is provided in the sliding seat 5 and is connected to the ball groove 12. The oil reservoir 15 is provided in the sliding seat 5 and is connected to the oil passage 14 through an oil pipe. The rubber plug 16 is inserted and removed on the oil filling hole above the oil reservoir 15. The rubber plug 16 can store the lubricating oil used by the six sets of balls 13.

[0021] like Figure 1 and Figure 2 As shown, the drive structure 3 includes a motor 17 fixedly mounted on one end of the guide rail body 1. A threaded rod 18 is fixedly mounted on the output shaft of the motor 17, and one end of the threaded rod 18 is threaded through the sliding seat 5 and rotatably mounted on the other end of the guide rail body 1.

[0022] In practical use, the motor 17 drives the threaded rod 18 to rotate, thereby driving the threaded rod 18 to repeatedly move the sliding seat 5 within the dovetail groove 4. After this, lubrication maintenance is required to ensure that the second ball 13 and the first ball 8 maintain good rolling action and avoid jamming, which would affect the precise movement effect. During maintenance, first open the rubber plug 10 on the oil filling hole connected to the first oil reservoir 9 and the rubber plug 16 on the oil filling hole connected to the second oil reservoir 15. Then, lubricate the oil through the oil filling hole above the first oil reservoir 9. Lubricating oil is injected into the oil reservoir 9, and at the same time, the oil pipe below the oil reservoir 9 guides the lubricating oil to the surface of the ball 8, so that the ball 8 can rotate on the ball groove 7 and the track 6, reducing friction. At the same time, lubricating oil is injected into the rubber plug 16 through the oil injection hole on the oil reservoir 15, and at the same time, the lubricating oil is guided to the surface of the ball 13 through the oil passage 14, so that the ball 13 can rotate on the ball groove 12 and the track 11, reducing friction and thus improving the accuracy of the ball screw module.
