Description

Airtight moving mechanism Technical Field The utility model relates to the technical field of linear movement modules, in particular to a closed movement mechanism. Background The ball screw is a transmission element most commonly used on tool machines and precision machines, and has the main function of converting rotary motion into linear motion or converting torque into axial repeated acting force, and simultaneously has the characteristics of high precision, reversibility and high efficiency. Ball screws are widely used in various industrial equipment and precision instruments due to their small frictional resistance. The existing ball screw is always directly exposed in an external working space, and some larger scraps generated in mechanical operation production can fall on the screw, so that the operation of the screw is influenced, and the normal operation of the screw is disturbed. Disclosure of Invention In view of the above, the present utility model provides a closed moving mechanism to solve the above-mentioned problems. A closed moving mechanism comprises a moving assembly, a dust-proof sheet arranged on the moving assembly and a dust-proof cover assembly arranged on the dust-proof sheet. The moving assembly comprises a track, a driving motor arranged on one side of the track, a screw rod arranged on the track and a nut seat arranged on the screw rod. The track is provided with a track groove, and the width of the dustproof sheet is larger than the width of the notch of the track groove. The nut seat is in the screw rod in a threaded connection mode, the end portion of the nut seat, which faces the dust cover component, protrudes out of the notch of the track groove, and an upper clamping block is arranged on the protruding end portion. One side of the upper clamping block, which faces the nut seat, is provided with a T-shaped groove, and the notch of the upper clamping block is welded and fixed with the nut seat. The dust cover assembly comprises a cover shell, two rollers and two pressing blocks, wherein the cover shell is covered on the upper clamping block, the two rollers are respectively arranged on two sides of the upper clamping block, and the two pressing blocks are respectively arranged on two opposite sides of the rollers. The two ends of the roller are rotatably arranged on the two inner side walls of the housing, and the tangent line of the roller, which is close to one end of the dust-proof sheet, and the notch of the track groove are positioned on the same horizontal line. The two pressing blocks are close to the end parts of the dustproof sheets and the notch of the track groove are positioned on the same horizontal line. Further, two ends of the track groove are respectively provided with a clamping piece close to the notch, and the dustproof sheet is clamped between the two clamping pieces. Further, both sides of the dust-proof sheet are abutted against the surface of the rail. Further, the nut seat is in a smooth arc shape along two edges of the dust-proof sheet in the length direction. Further, a gap which is movably penetrated through the dustproof sheet is arranged between the upper clamping block and the nut seat. Further, two inner side walls of the housing are fixedly connected with two sides of the upper clamping block respectively. Compared with the prior art, the sealed moving mechanism provided by the utility model has the advantages that the dust-proof sheets at the two ends of the nut seat are pressed by the two rollers, so that overlarge gaps caused by overlarge bulge of the dust-proof sheets are avoided, overlarge gaps between the dust-proof sheets and the notch of the track groove are avoided, fragments fall into the gaps, and smooth running of the screw rod is ensured. The two pressing blocks can always press the dustproof sheet at the notch of the track groove, so that shaking caused by movement of the housing due to the dustproof sheet is avoided, gaps are formed between the dustproof sheet and the notch of the track groove, and chips fall into the track groove to interfere with operation of the screw rod.
