Description

Technical Field

[0001] This utility model relates to the field of linear motion module technology, and in particular to a sealed motion mechanism. Background Technology

[0002] Ball screws are the most commonly used transmission components in machine tools and precision machinery. Their main function is to convert rotary motion into linear motion, or torque into axial reciprocating force, while also possessing the characteristics of high precision, reversibility, and high efficiency. Due to their very low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. However, existing ball screws are often directly exposed in the external working space. Larger debris generated during mechanical operations can fall onto the screw, affecting its operation and interfering with its normal operation. Summary of the Invention

[0003] In view of this, the present invention provides a sealed moving mechanism to solve the above problems.

[0004] A sealed moving mechanism includes a moving component, a dustproof sheet disposed on the moving component, and a dustproof cover assembly disposed on the dustproof sheet. The moving component includes a track, a drive motor disposed on one side of the track, a lead screw disposed on the track, and a nut seat disposed on the lead screw. A track groove is formed in the track, and the width of the dustproof sheet is greater than the width of the track groove opening. The nut seat is screwed onto the lead screw, and the end of the nut seat facing the dustproof cover assembly protrudes from the opening of the track groove, with an upper clamping block disposed on the protruding end. A T-slot is formed on the side of the upper clamping block facing the nut seat, and the opening of the upper clamping block is welded to the nut seat. The dustproof cover assembly includes a cover shell covering the upper clamping block, two rollers respectively disposed on both sides of the upper clamping block, and two pressure blocks respectively disposed on the opposing sides of the two rollers. The roller is rotatably mounted on the two inner sidewalls of the housing, and the tangent of the roller near the dustproof sheet is at the same horizontal line as the opening of the track groove. The ends of the two pressure blocks near the dustproof sheet are at the same horizontal line as the opening of the track groove.

[0005] Furthermore, a clamping piece is provided at each end of the track groove near the groove opening, and the dustproof piece is clamped between the two clamping pieces.

[0006] Furthermore, the two sides of the dustproof sheet abut against the surface of the track.

[0007] Furthermore, the nut seat has two smooth arc-shaped edges along the length of the dustproof sheet.

[0008] Furthermore, there is a gap between the upper clamping block and the nut seat that allows the dustproof sheet to pass through.

[0009] Furthermore, the two inner sidewalls of the cover are fixedly connected to the two sides of the upper clamping block, respectively.

[0010] Compared with the prior art, the sealed moving mechanism provided by this utility model uses two rollers to press the dustproof plates at both ends of the nut seat, avoiding excessive gaps caused by excessive bulging of the dustproof plates. This prevents debris from falling into the groove due to excessive gaps between the dustproof plates and the groove opening, ensuring the smooth operation of the lead screw. The two pressure blocks can keep the dustproof plates pressed against the groove opening, preventing the dustproof plates from shaking due to the movement of the cover, thus preventing gaps from forming between the dustproof plates and the groove opening, which would cause debris to fall into the groove and interfere with the operation of the lead screw.

[0012] Figure 2 for Figure 1 A cross-sectional schematic diagram of a closed moving mechanism. Detailed Implementation

[0013] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0014] like Figure 1 The diagram shown is a structural schematic of the sealed moving mechanism provided by this utility model. The sealed moving mechanism includes a moving component 10, a dustproof sheet 20 disposed on the moving component 10, and a dust cover assembly 30 disposed on the dustproof sheet 20. It is conceivable that the sealed moving mechanism also includes other functional modules, such as a power module, a screw module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0015] Please see Figure 2 The moving component 10 includes a track 11, a drive motor 12 disposed on one side of the track 11, a lead screw 13 disposed on the track 11, and a nut seat 14 disposed on the lead screw 13.

[0016] A track groove 15 is provided on the track 11. A clamping piece 16 is provided at each end of the track groove 15 near the groove opening. The two clamping pieces 16 clamp the two ends of the dustproof sheet 20, thereby laying the dustproof sheet 20 at the groove opening of the track groove 15.

[0017] The width of the dustproof sheet 20 is greater than the width of the groove of the track groove 15. When the dustproof sheet 20 is laid flat on the track groove 15, the two sides of the dustproof sheet 20 abut against the surface of the track 11. In this way, the dustproof sheet 20 can block the debris generated during operation, prevent the debris from entering the track groove 15 and interfering with the operation of the lead screw 13, thereby protecting the lead screw 13 and improving the service life of the moving mechanism.

[0018] The lead screw 13 is rotatably disposed in the track groove 15, and one end of the lead screw 13 is rotatably connected to the drive motor 12 via a belt, so that the lead screw 13 can rotate under the drive of the drive motor 12.

[0019] The nut seat 14 is screwed onto the lead screw 13. The end of the nut seat 13 facing the dust cover assembly 30 protrudes from the groove of the track groove 15, and an upper clamping block 17 is provided on the protruding end. The upper clamping block 17 has a T-shaped groove on the side facing the nut seat 14, and the groove of the upper clamping block 17 is welded and fixed to the nut seat 14, so that there is a gap between the upper clamping block 17 and the nut seat 14 that allows the dust cover 20 to move through. The two edges of the nut seat 14 along the length of the dust cover 20 are smooth arc-shaped so that the dust cover 20 can pass smoothly between the nut seat 14 and the upper clamping block 17.

[0020] The dust cover assembly 30 includes a cover 31 covering the upper clamping block 17, two rollers 32 respectively disposed on both sides of the upper clamping block 17, and two pressure blocks 33 respectively disposed on the opposite side of the two rollers 32.

[0021] The two inner sidewalls of the cover 31 are fixedly connected to the two sides of the upper clamping block 17, so that the cover 31 can move together with the upper clamping block 17.

[0022] The roller 32 is rotatably mounted on the two inner sidewalls of the cover 31 at both ends, and the tangent of the roller 32 near the dustproof sheet 20 is at the same horizontal line as the opening of the track groove 15. Since the nut seat 14 protrudes from the opening of the track groove 15, the dustproof sheet 20 will slightly bulge when it enters the gap between the nut seat 14 and the upper clamping block 17. During the movement of the nut seat 14, the upper clamping block 17, and the cover 31, the roller 32 can roll on the surface of the dustproof sheet 20, thereby pressing down on the dustproof sheet 20 and preventing excessive gaps caused by excessive bulging of the dustproof sheet 20. This also prevents debris from falling into the gap between the dustproof sheet 20 and the opening of the track groove 15, ensuring the smooth operation of the lead screw 13.

[0023] The ends of the two pressure blocks 33 near the dustproof sheet 20 are on the same horizontal line as the opening of the track groove 15. In this way, during the movement of the cover 31, the dustproof sheet 20 can always be pressed against the opening of the track groove 15, avoiding the dustproof sheet 20 from shaking due to the movement of the cover 31. This prevents gaps from forming between the dustproof sheet 20 and the opening of the track groove 15, which would cause debris to fall into the track groove 15 and interfere with the operation of the lead screw 13.

[0024] Compared with the prior art, the sealed moving mechanism provided by this utility model uses two rollers 32 to press the dustproof plates 20 at both ends of the nut seat 14, avoiding excessive gaps caused by excessive bulging of the dustproof plates 20, and preventing debris from falling into the groove 15 due to excessive gaps between the dustproof plates 20 and the groove, thus ensuring the smooth operation of the lead screw 13. The two pressure blocks 33 can keep the dustproof plates 20 pressed against the groove of the track 15 at all times, preventing the dustproof plates 20 from shaking due to the movement of the cover 31, thus preventing gaps from appearing between the dustproof plates 20 and the groove of the track 15, which would cause debris to fall into the track 15 and interfere with the operation of the lead screw 13.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
