Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing, and in particular to a screw tightening device for a flat knitting machine motor. Background Technology

[0002] Currently, in the field of motor manufacturing, various components of a motor are usually connected and assembled using screws, especially the motor rotor, which is typically assembled by tightening screws.

[0003] In the existing technology, screw tightening is mainly done manually. Specifically, as the production line moves, an electric screw tightening device is used manually to screw the screws into the fixing holes to make a fixed connection and tighten the parts together.

[0004] The current method of manually screwing screws on the assembly line is inefficient and the quality is difficult to guarantee. This affects the orderly production process and makes it difficult to meet the needs of modern motor manufacturing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a screw tightening device for the motor of a flat knitting machine, based on the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A screw tightening device for a flat knitting machine motor includes a tightening device body, which includes a bracket, a tightening part disposed on the bracket, and a placement part disposed at the lower end of the tightening part. The tightening part is equipped with a drive motor for vertical movement. The placement part is equipped with a push motor and a pre-installation position. After the user places a fixture in the pre-installation position, the push motor moves it below the tightening part to form a first stroke. The drive motor then drives the tightening part downwards to tighten the fixture, forming a second stroke. The drive motor then moves the tightening part upwards, and subsequently the push motor pushes the pre-installation position away from the tightening part, forming a third stroke.

[0008] The aforementioned components achieve the following effects: The main body of the tightening device enables the tightening of screws on the motor; the tightening section enables the tightening of screws on the motor; the placement section enables the placement of the motor; the pre-installation position limits the placement of the motor; the push motor limits and pushes the pre-installation position; and the first, second, and third strokes allow the screws to be tightened onto the motor within the main body of the tightening device, eliminating the need for manual tightening, reducing working time, and improving work efficiency.

[0009] Preferably, the tightening part includes at least one tightening head and a tightening motor disposed above the tightening head; a fixing plate is disposed between the tightening head and the tightening motor; a fixing piece is disposed on the fixing plate; the tightening motor is mounted on the fixing plate through the fixing piece.

[0010] The aforementioned components achieve the following effects: a tightening head is provided for tightening screws; a tightening motor is provided to drive the tightening head during tightening; and a fixing plate and a fixing piece are provided so that the tightening motor can be mounted on the fixing plate, thereby improving the stability of the structure.

[0011] Preferably, a hydraulic rod is provided between the bracket and the fixed plate; one end of the hydraulic rod is connected to the drive motor; the fixed plate is limited to move by the drive motor and the hydraulic rod.

[0012] The effect achieved by the above components is as follows: by setting up a hydraulic rod, and connecting one end of the hydraulic rod to the drive motor, after the drive motor drives the fixed plate to move up and down to the limit, the tightening head and the tightening motor can move up and down to the limit together.

[0013] Preferably, the placement part is further provided with a sliding part; the push motor is provided at the upper end of the sliding part; the pre-installation position is provided at the upper end of the push motor; the pre-installation position moves at the upper limit of the sliding part by the push motor.

[0014] The effect achieved by the above components is that by setting a sliding part, the push motor can move at the upper limit of the sliding part, and the pre-installed position slides at the limit on the sliding part along with the push motor.

[0015] Preferably, a sensing unit is provided below the tightening part; the sensing unit is connected to or separated from the push motor; the sensing unit is electrically connected to the push motor, the drive motor, and the tightening motor.

[0016] The effect achieved by the above components is that by setting up a sensing unit, the drive motor stops working when it comes into contact with the sensing unit, and then the drive motor and the tightening motor can work.

[0017] Compared with the prior art, the advantages of this utility model are as follows: The main body of the tightening device enables the tightening of screws on the motor; the tightening part enables the tightening of screws on the motor; the placement part enables the placement of the motor; the pre-installation position limits the placement of the motor; the push motor limits and pushes the pre-installation position; and the first, second, and third strokes allow the screws to be tightened onto the motor within the main body of the tightening device, eliminating the need for manual tightening, reducing working time, and improving work efficiency.
