Description

Technical Field

[0001] This utility model relates to the field of reciprocating machine technology, and more specifically, to a smooth transmission device for the walking mechanism of a left and right mirror motor. Background Technology

[0002] In the automated powder coating process, a reciprocating machine is needed to control the spray gun, enabling it to move and be positioned for localized spraying of the workpiece. The reciprocating machine used for powder coating generally consists of a simple square guide rail, a load mechanism with pulleys, and a transmission mechanism. The pulleys drive the load mechanism to move up and down along the square guide rail. The stability of the reciprocating machine's lifting and traveling mechanism is crucial to the accuracy of automated powder coating production, especially for more precise spraying.

[0003] The existing reciprocating machine uses a square guide rail that only has one side in contact with the pulley block. This greatly affects the stability of the load mechanism during the lifting and lowering process. In addition, after long-term use, the stability of the entire lifting mechanism is easily reduced due to local wear.

[0004] A search revealed a Chinese patent with publication number CN206046346U that discloses a stable and efficient reciprocating machine lifting and traveling mechanism. This utility model uses a T-shaped guide rail and a first pulley group and a second pulley group that cooperate with it. The first pulley group clamps the middle protrusion of the T-shaped guide rail to achieve the load function; the second pulley group abuts against the T-shaped guide rail to achieve the limiting function. This double-sided abutment and sliding structure gives the entire reciprocating machine lifting and traveling mechanism excellent stability, while also having the advantages of efficient positioning and long service life.

[0005] However, in actual use, when the aforementioned reciprocating lifting and traveling mechanism is replaced with different types of guide rails, the pulley block of the traveling mechanism and the edge of the guide rail cannot fit well, which will reduce the transmission stability between the traveling mechanism and the guide rail and reduce the applicability of the traveling mechanism. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a smooth transmission device for the walking mechanism of a left and right mirror motor to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A smooth transmission device for the walking mechanism of a left-right mirror motor includes a guide frame with multiple toothed grooves on its inner side and a guide groove inside the guide frame. A sliding seat is slidably connected inside the guide frame, and a mounting bracket is fixedly connected to the upper surface of the sliding seat. A positioning mechanism is provided at the bottom of the sliding seat. The positioning mechanism includes two fixed brackets, the outer side of which is slidably connected to the inner side of the sliding seat. Multiple slots are provided on the inner side of the sliding seat, and bolts are inserted into the inner sides of the fixed brackets and slots. One end of each bolt is threaded to the inner side of the sliding seat. Multiple supports are fixedly connected to the bottom of the fixed brackets, and rollers are rotatably connected to the outer side of each support. Multiple fixed rings are fixedly connected to the bottom of the sliding seat, and an electric push rod is fixedly connected to the inner side of each fixed ring. One end of the electric push rod is fixedly connected to a second support, and two rollers are rotatably connected to the outer side of the second support. A transmission mechanism is provided on the outer side of the sliding seat.

[0009] By adopting the above technical solution: using multiple brackets and rollers to provide rolling support to the inner wall of the guide groove, and combining multiple electric push rods to provide telescopic support to the inner wall of different guide frames, the sliding seat can be installed inside different types of guide frames, ensuring that the sliding seat and the guide frame are symmetrically stressed, preventing unilateral overload of the sliding seat, and keeping the sliding seat stable in motion.

[0010] As a further description of the above technical solution: the transmission mechanism includes two cylinders, the outer side of the cylinder is fixedly connected to the inner side of the sliding seat, a connecting plate is fixedly connected to one end of the cylinder, the outer side of the connecting plate is slidably connected to the inner side of the sliding seat, two outer cylinders are fixedly connected to one side of the connecting plate, a push rod is slidably connected to the inner side of the outer cylinder, a spring is sleeved on the outer side of the push rod, one end of the spring is fixedly connected to one side of the outer cylinder, a second fixing frame is fixedly connected to one side of the push rod, one side of the second fixing frame is fixedly connected to the other end of the spring, a transmission gear is rotatably connected to the inner side of the second fixing frame, a variable frequency motor is fixedly connected to the top of the second fixing frame, and the output end of the variable frequency motor is fixedly connected to the inner side of the transmission gear.

[0011] By adopting the above technical solution, the connecting plate, outer cylinder, push rod, spring, and fixed frame driven by two sets of cylinders maintain strong elastic support for the two tooth grooves inside the two pairs of guide frames, so that the tooth grooves and transmission gears can maintain full meshing, and the sliding seat can maintain stable transmission operation.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a positioning mechanism, compared with the existing technology, multiple sets of rollers one and two are distributed along the walking direction to provide uniform support for different types of sliding seats, enhance the overall rigidity of the entire walking mechanism, and evenly transfer the load to the inner wall of the guide frame, avoid local stress concentration, prevent bending or torsional deformation under load, ensure symmetrical force, prevent unilateral overload, and improve the anti-eccentric load capacity and applicability of the walking mechanism in different types of sliding seats.

[0014] 2. By setting up a transmission mechanism, compared with the existing technology, the transmission gears on the left and right sides continuously press against the tooth surface of the guide frame and tooth groove under the elastic support, which can automatically compensate for the wear between the transmission gear and tooth groove, always maintain close contact, avoid idle stroke caused by gaps, eliminate transmission gaps, and maintain stability during frequent reversals.

Two rollers 14 are rotatably connected to the outer side of the bracket 13. A transmission mechanism is provided on the outer side of the slide seat 4. Multiple electric push rods 12 on the inner side of the slide seat 4 push the bracket 13 and rollers 14 to provide opposing support between the slide seat 4 and the guide frame 1, so that the slide seat 4 can be installed with guide frames 1 of different models. Two fixed frames 6 that can slide up and down can move up and down on the inner side of the slide seat 4. Multiple brackets 9 and rollers 10 on the bottom side of the fixed frames 6 roll and limit the inner side of the guide groove 3, so that the slide seat 4 evenly transmits the load to the inner wall of the guide frame 1 during operation, ensuring symmetrical force.

[0024] Reference Figure 1 and Figure 5As shown, the transmission mechanism includes two cylinders 15. The outer side of each cylinder 15 is fixedly connected to the inner side of the sliding seat 4. A connecting plate 16 is fixedly connected to one end of each cylinder 15. The outer side of the connecting plate 16 is slidably connected to the inner side of the sliding seat 4.

A second fixing frame 20 is fixedly connected to one side of each push rod 18. One side of the second fixing frame 20 is fixedly connected to the other end of the spring 19. The inner side of the second fixing frame 20 can rotate.

The groove 2 engages, and multiple springs 19 elastically push the inner wall of the guide frame 1 against the fixed brackets 20 on both sides and the transmission gears 21, so that the sliding seat 4 can maintain the stability of movement inside the guide frame 1. Then, two variable frequency motors 22 are started to drive the transmission gears 21 to rotate in opposite directions, so that the two transmission gears 21 engage with the tooth grooves 2 on both sides of the guide frame 1. Combined with the rolling support of multiple rollers 14 on the inner wall of the guide frame 1 and the rolling support of multiple rollers 10 on the inner wall of the guide groove 3, the sliding seat 4 can be installed in different types of guide frames 1 to maintain stable transmission.
