[0025] Embodiment 1, as shown in the accompanying drawings Figure 1 - the accompanying drawings Figure 4The utility model provides a technical scheme: a motor special self -lubricating coating guide rail, including guide rail body 1, the inside wall fixedly connected with rack 2 of guide rail body 1 is equipped with the movable sleeve of slider 3 of guide rail body 1 outside wall, the top fixedly connected with two bearing seats 4 of slider 3, the inside fixed insertion of two bearing seats 4 is equipped with worm 5, the fixedly connected with drive motor 6 of one side of the outer wall of worm 5, the inside fixed insertion of slider 3 is equipped with first bearing 7, the inside fixed insertion of first bearing 7 is equipped with shaft 8, the fixed sleeve of the outer surface wall of shaft 8 is equipped with worm wheel 9, and the outer wall of worm wheel 9 is engaged with the outer wall of worm 5, and the bottom fixedly connected with first engagement disc 10 of shaft 8, the bottom fixedly connected with fixed frame 11 of slider 3, the inside wall fixed insertion of fixed frame 11 is equipped with second bearing 12, the inside fixed insertion of second bearing 12 is equipped with fixed screw 13, the fixed sleeve of the outer surface wall of fixed screw 13 is equipped with gear 14, and the outer wall of gear 14 is engaged with the outer wall of rack 2, and the outer wall of fixed screw 13 is engaged with fixed nut 15, and the top of fixed screw 13 is provided with two limit slots 16, and the inside of two limit slots 16 is movably inserted with limit rod 17, and the outer surface wall between two limit rods 17 is fixedly connected with rotating rod 18, and the top of rotating rod 18 is fixedly connected with second engagement disc 19, and the outer surface wall movable sleeve of fixed screw 13 is equipped with buffer spring 20.
[0026] The effect achieved by the whole embodiment 1 is that during the operation of the equipment, the drive motor 6 operates to drive the worm 5 to rotate, based on the meshing transmission principle of the worm wheel 9 and the worm 5, the shaft 8 is driven to rotate, because the first engagement disc 10 and the second engagement disc 19 are engaged with each other, the gear 14 is driven to rotate through the transmission between the two engagement discs, and the sliding block 3 is moved along the guide rail body 1 through the meshing transmission of the gear 14 and the rack 2, when the sliding block 3 is suddenly blocked by foreign matter or the load suddenly changes, because the transmission system suddenly bears a great resistance, the torque transmitted between the first engagement disc 10 and the second engagement disc 19 sharply increases, the increased torque then overcomes the elastic force of the buffer spring 20 at the bottom of the second engagement disc 19, the second engagement disc 19 is forced to move downward and compress, at this time, the first engagement disc 10 and the second engagement disc 19 are disengaged from the engagement state and are in the situation of slipping, thereby interrupting the power transmission path of the drive motor 6, preventing the drive motor 6 from being burned out due to the excessive current caused by overloading, in addition, the compression amount of the buffer spring 20 can be adjusted by rotating the fixed nut 15, so that the buffer spring 20 can provide the buffer spring force according to the actual working condition requirement.
[0027] Embodiment 2, as Figures 2-4As shown, the bottom of the driving motor 6 is fixedly connected with two embedded blocks 21, the outer wall of the two embedded blocks 21 is provided with a clamping groove 22, the inner wall of the two clamping grooves 22 is movably inserted with a clamping block 23, the outer wall of the two clamping blocks 23 is fixedly connected with a pull plate 24, and the outer wall of the pull plate 24 is fixedly connected with a reset spring 25.
[0028] The effect achieved by the whole embodiment 2 is that when the driving motor 6 needs to be maintained or replaced, first, the pull plate 24 is pulled, the pull plate 24 drives the two clamping blocks 23 to move outwardly against the elastic force of the two reset springs 25, so that the two reset springs 25 are stretched and store elastic potential energy, when the two clamping blocks 23 are completely moved out of the corresponding clamping grooves 22, the fixing constraint of the two embedded blocks 21 is released, then the driving motor 6 can be disassembled for subsequent maintenance or replacement, and when the driving motor 6 is installed, the elastic force of the reset spring 25 released to restore the original state can make the two clamping blocks 23 be clamped into the corresponding clamping grooves 22, so that the driving motor 6 and the sliding block 3 form a stable mortise and tenon connection, ensuring that the driving motor 6 is stable and reliable during operation, and will not be loose or displace.
[0029] The working principle of the whole device is as follows: in use, the driving motor 6 starts to operate to drive the worm 5 to rotate synchronously, according to the transmission principle of the worm 5 and the worm wheel 9, the worm wheel 9 starts to rotate under the driving of the worm 5, and then drives the rotating shaft 8 connected thereto to rotate, since the first engaging disc 10 and the second engaging disc 19 are in the state of mutual engagement, the rotation of the rotating shaft 8 drives the gear 14 to rotate through the transmission of the two engaging discs, the gear 14 and the rack 2 are in engagement with each other, in the rotating process of the gear 14, the sliding block 3 is driven to move along the guide rail body 1 through the engagement transmission of the two, when the sliding block 3 suddenly encounters foreign matter or load instantaneously changes during operation, the whole transmission system will instantaneously bear a great resistance, the resistance will cause the torque transmitted between the first engaging disc 10 and the second engaging disc 19 to increase sharply, the sharply increased torque then overcomes the elastic force of the buffer spring 20 at the bottom of the second engaging disc 19, and forces the second engaging disc 19 to move downward and compress the buffer spring 20, at this time, the first engaging disc 10 and the second engaging disc 19 are disengaged from the engagement state and enter the slipping state, which cuts off the power transmission path of the driving motor 6, effectively prevents the driving motor 6 from being burned due to the excessive current caused by overload, and protects the driving motor 6, and meanwhile, the compression amount of the buffer spring 20 can be adjusted by rotating the fixed nut 15, so that the buffer spring 20 can provide the buffer spring force according to the load change, the running speed and other factors of the actual working condition, so as to better cope with different working conditions, when the driving motor 6 needs to be maintained or replaced, first pull the pull plate 24, the pull plate 24 drives the two clamping blocks 23 to move outward to overcome the elastic force of the two return springs 25, so that the two return springs 25 are stretched and store elastic potential energy, when the two clamping blocks 23 are completely moved out of the corresponding clamping grooves 22, the fixing constraint of the two embedded blocks 21 is released, then the driving motor 6 can be disassembled for subsequent maintenance or replacement, when the driving motor 6 is installed, only need to insert the embedded blocks 21 on the driving motor 6 into the corresponding slot holes at the top of the sliding block 3, at this time, the elastic force of the two return springs 25 is released to restore the original state, so that the two clamping blocks 23 are clamped into the corresponding clamping grooves 22, so that the driving motor 6 and the sliding block 3 form a stable mortise and tenon connection, and the driving motor 6 is stable and reliable during operation, and will not be loose or displace.
