Description

Spring pressure adjusting device
Technical Field
The invention relates to a spring pressure adjusting device, and belongs to the field of professional electric tools.
Background
Spring pressure adjustment of electric tools in the market at present shows the characteristics of easy operation and convenient adjustment, but for professional electric tools used in factory assembly lines, what is needed is that once the spring pressure adjustment is set, the spring pressure adjustment cannot be easily changed and adjusted. Therefore, the professional electric tool needs a device for adjusting the pressure of the spring in the whole machine, and the device is convenient for managers to adjust the pressure parameters on the premise that the pressure parameters cannot be changed when the workers operate the device.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: how to design the device of adjusting spring pressure in the complete machine, can't change pressure parameter when letting the workman operate promptly, can make things convenient for the device of managers adjustment pressure parameter again.
In order to solve the technical problem, the technical scheme of the invention is to provide a spring pressure adjusting device which is characterized by comprising a main shaft, wherein the front end of the main shaft is provided with a spring washer, the spring washer is connected with a compression spring, the other end of the compression spring is connected with a D-hole non-return pad, the D-hole non-return pad is connected with an end tooth nut, and a special adjusting rod is arranged and can be inserted into the D-hole non-return pad to adjust the end tooth nut.
Preferably, the D-hole check pad is provided with a jack which can be matched with the adjusting rod, and is also provided with a positioning round-head salient point matched with the end tooth nut and a D-shaped hole which is connected with the main shaft to prevent rotation.
Preferably, the end tooth nut is provided with a uniform tooth-shaped groove capable of matching with the adjusting rod adjusting teeth, and is also provided with an internal thread matched with the main shaft thread.
Preferably, the special adjusting rod is provided with adjusting teeth.
The invention has the characteristics that the device for adjusting the spring pressure is designed in the whole machine, so that the pressure parameter can not be changed when a worker operates the machine, and the manager can conveniently adjust the pressure parameter.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a detail view of the D-hole check pad of the present invention;
fig. 3 is a detail view of the end tooth nut of the present invention.
Detailed Description
In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the present invention relates to a spring pressure adjusting apparatus, characterized in that: the device includes: the device comprises a main shaft 1, a spring washer 2, a compression spring 3, a special adjusting rod 4, a D-hole check pad 5 and an end tooth nut 6. The D-hole check pad 5 is provided with a D-shaped inner hole 5-3 for preventing rotation, the outer circle is provided with an insertion hole 5-1 for propping against the adjusting rod 4, and the end surface is provided with a round head salient point 5-2 for positioning; the end face of the end tooth nut 6 is provided with a tooth-shaped groove 6-1, and the inner circle of the end tooth nut is provided with an internal thread 6-2 matched with the thread of the main shaft 1; the head of the special adjusting rod 4 is provided with adjusting teeth.
In the working process of the invention, the hole D check pad 5 can move back and forth on the main shaft 1, and the end tooth nut 6 can rotate back and forth on the main shaft 1 through threads. The special adjusting rod 4 is inserted into the D-hole check pad 5 to screw the end tooth nut 6, so that after the round head salient point 5-2 of the D-hole check pad 5 and the tooth-shaped groove 6-1 of the end tooth nut 6 are tripped, the end tooth nut 6 is rotated to move back and forth on the main shaft 1 according to the internal thread 6-2, and the D-hole check pad 5 is pushed and the compression spring 3 is adjusted. After the pressure of the spring is adjusted to be in place, the special adjusting rod 4 is taken out, the round-head salient points 5-2 of the hole D check pad 5 are meshed with the tooth-shaped grooves 6-1 of the end tooth nuts 6 again, and the positioning effect is achieved. Therefore, even if the machine shakes or the operator operates by mistake after the tightening, the adjusted torque force cannot be influenced.
