[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides an easily adjustable trimming device through improvement. The technical solution of the utility model is:

[0024] like Figure 1 and Figure 2 As shown, a trimming device that is easy to adjust includes a base 1, which is a hollow rectangular structure. A cylinder 2 is fixedly installed on the top wall of the base 1, and the output end of the cylinder 2 penetrates downwardly through the top wall of the base 1. A cutting knife 3 is fixedly installed on the output end of the cylinder 2. The cylinder 2 drives the cutting knife 3 to move downward to trim the motor housing. A positioning mechanism is provided on the base 1. A movable seat 9 is movably installed in the base 1 corresponding to the position of the cutting knife 3. The movable seat 9 is a block of a rectangular structure. An installation groove 10 is opened inside the movable seat 9. The installation groove 10 is a cylindrical groove. The installation groove 10 is fixedly installed inside the base 1. A limiting rod 11 is fixedly installed inside the base 1. The limiting rod 11 is a cylindrical structure. The top of the limiting rod 11 is located inside the installation groove 10. A reset spring 12 is movably sleeved on the limiting rod 11. A collecting mechanism is provided on the base 1.

[0025] like Figure 2 and Figure 3As shown, the collecting mechanism includes a stop block 13, a collecting box 14, a collecting slot 15, a guide block 16, a torsion spring shaft 17 and a movable plate 18. The stop block 13 is a rectangular block, which is fixedly mounted on the cutting knife 3. The top wall of the movable seat 9 is an inclined surface. The collecting box 14 is a hollow rectangular structure, which is embedded and movably mounted inside the front side of the base 1. The collecting slot 15 is a rectangular slot, which is opened on the top wall of the base 1 at a position corresponding to the collecting box 14. The collecting slot 15 penetrates downwardly through the top wall of the base 1 and is connected with the inside of the collecting box 14. The guide block 16 is a triangular block, which is fixedly mounted on the base 1 between the movable seat 9 and the collecting slot 15. The top of the guide block 16 is an inclined surface. The torsion spring shaft 17 is movably installed on the inner front side of the collecting groove 15, and the movable plate 18 is a rectangular structure plate. The movable plate 18 is fixedly sleeved on the torsion spring shaft 17. When trimming, the motor housing is first fixed by the positioning mechanism, and then the cylinder 2 is started. The cylinder 2 drives the cutting knife 3 downward to cut the corners of the motor housing. At the same time, the stop block 13 on the cutting knife 3 will squeeze the movable seat 9, and the movable seat 9 moves downward. The cut waste chips will move along the inclined surface of the movable seat 9 to the guide block 16, and then fall onto the movable plate 18. Under the action of gravity, the movable plate 18 will flip over. At this time, the waste chips on the movable plate 18 will be collected in the inside of the collecting box 14, thereby achieving the effect of collecting the generated waste chips at the same time during trimming.

[0026] like Figure 2 and Figure 4 As shown, in one embodiment, the positioning mechanism includes a push plate 4, a drive motor 5, a movable groove 6, a transmission shaft 7 and a transmission block 8. The push plate 4 is a rectangular plate, which is embedded in the side wall inside the base 1. The drive motor 5 is fixedly installed below the left outer wall of the base 1. The movable groove 6 is a rectangular groove, which is opened on the left side of the base 1. The transmission shaft 7 is a cylindrical structure with threads. The transmission shaft 7 is movably installed in the movable groove 6, and the transmission shaft 7 is fixedly connected to the output end of the drive motor 5. The transmission block 8 is a rectangular block with the same size as the inside of the movable groove 6. The transmission block 8 is movably installed in the movable groove 6. The transmission shaft 7 penetrates the side wall of the transmission block 8 and is threadedly connected to the transmission block 8, and the transmission block 8 is fixedly connected to the push plate 4, so that when the drive motor 5 is started to rotate the transmission shaft 7, the transmission block 8 will move inside the movable groove 6, thereby driving the push plate 4 to move. The movement of the push plate 4 can squeeze and position the motor housing on the base 1, thereby achieving the effect of easy adjustment and the effect of fixing motor housings of different sizes.

[0027] like Figure 1 or Figure 2As shown, in one embodiment, two fixed magnetic blocks 19 are embedded and installed on the push plate 4. The fixed magnetic blocks 19 are circular structures. When the motor housing is placed on the front side of the push plate 4, the fixed magnetic blocks 19 can adsorb the motor housing, thereby preventing the motor housing from being offset when the push plate 4 moves.

[0028] The specific working methods are:

[0029] When trimming, the motor housing is first fixed by the positioning mechanism, and then the cylinder 2 is started. The cylinder 2 drives the cutting knife 3 downward to cut the corners of the motor housing. At the same time, by providing a collecting mechanism, the stop block 13 on the cutting knife 3 will squeeze the movable seat 9, and the movable seat 9 moves downward. The cut waste chips will move along the inclined surface of the movable seat 9 to the guide block 16, and then fall onto the movable plate 18. Under the action of gravity, the movable plate 18 will flip over. At this time, the waste chips on the movable plate 18 will be collected in the collecting box 14, thereby achieving the effect of collecting the generated waste chips at the same time during trimming.
