Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the first and fifth devices according to the embodiment of the present invention.

Detailed Description

The first embodiment is as follows:

the embodiment is an electric driving feeding device of a thread rolling machine, and is shown in figure 1. The embodiment comprises the following steps: the automatic thread rolling machine is characterized in that the automatic thread rolling machine comprises a feeding groove 1 arranged on one side of a thread rolling station on a thread rolling machine body, a push rod 3 for pushing a workpiece into the thread rolling station 2 is arranged at the outlet end of the feeding groove, the push rod is pushed by an electric driving component 4, and the electric driving component is electrically connected with a thread rolling monitoring sensor 5 through a thread rolling machine controller.

The thread rolling station described in this embodiment is composed of a sliding thread rolling support plate 6 and a fixed thread rolling support plate 7. The sliding thread rolling supporting plate is driven by a crank rocker mechanism (not shown in figure 1) to do reciprocating motion, so that thread rolling action is generated. The rotating wheel of the crank rocker mechanism is driven by a main motor through a gear box 8 and a belt pulley 9. The feeding device has the function that the workpiece 10 is pushed into the thread rolling station from the feeding groove by the push rod to perform thread rolling operation, and the push rod is driven by the electric driving component to do linear motion.

The electric driving component described in this embodiment can be various driving components that directly change the rotational motion of the motor into a linear motion. With the advancement of mechatronics, there are a number of members that directly change the rotational motion of a motor into linear motion. The components comprise various components directly driven by a motor, such as an electric push rod, an electric cylinder, an electric sliding table and the like, and the components can be driven by directly using electric power without using a driving station required by linear motion components such as an oil cylinder, an air cylinder and the like. The electric drive is used to make the start and stop very convenient, and no sensor is needed to transmit signals, thus greatly simplifying the control of the electric appliance. For example, in this embodiment, a thread rolling quality monitoring sensor may be disposed at a thread rolling station to perform online real-time monitoring on a thread rolling process, and once the thread rolling quality does not meet a requirement, the machine may be stopped to alarm, or defective products may be respectively output through a branch material passage controlled by a solenoid valve.

The push rod for conveying the work piece must be completely coordinated with the action of the sliding thread rolling pallet, otherwise a wrong action will occur. In the embodiment, the push rod is driven by the electric driving component, so that the sliding screw plate and the push rod can be coordinated by using electric signals, and the key point is how to transmit the action signals of the sliding screw plate to the electric driving workpiece for driving the push rod to move. In the embodiment, a mode of arranging a thread rolling monitoring sensor is adopted, namely, the motion process of the sliding thread rolling supporting plate is recorded by the thread rolling monitoring sensor and is transmitted to a thread rolling controller, and the thread rolling controller controls the action of the electric driving component according to the relative relation between the position of the sliding thread rolling supporting plate and the position of a workpiece, so that correct material conveying is realized.

The thread rolling monitoring sensor can be an encoder arranged on a transmission shaft of a rotating wheel which drives a sliding thread rolling supporting plate to do reciprocating motion, and the encoder is used for recording the rotation of the rotating wheel so as to determine the position of the sliding thread rolling supporting plate. The thread monitor sensor may also be a grating detector mounted on the sliding thread tray, which determines the position of the sliding thread tray by reading the grating. Or other sensors are adopted to detect the position of the sliding thread rolling supporting plate, such as a laser radar and the like, so that the function of monitoring the position of the sliding thread rolling supporting plate can be realized.

Example two:

the present embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding the electric driving member. The electric driving component described in this embodiment is one of an electric cylinder, an electric sliding table, and an electric push rod.

The electric sliding table has a high operation precision due to the guide rail, but the cost is high. The precision of the electric cylinder is moderate, the precision of the electric push rod is relatively low, the electric push rod can also be applied to a material conveying push rod, and the price of the two types of construction is relatively low.

Example three:

the present embodiment is a modification of the above-described embodiments, and is a refinement of the above-described embodiments with respect to the thread rolling monitoring sensor. The thread rolling monitoring sensor described in this embodiment is an encoder installed on a transmission shaft that drives a sliding thread rolling carriage to reciprocate.

The rotating wheel driving the sliding thread rolling carriage to reciprocate is a part directly driving the sliding thread rolling carriage to move, and the sliding thread rolling carriage reciprocates once when the rotating wheel rotates for one circle, so that a coder arranged on a transmission shaft of the rotating wheel can accurately record the motion track of the sliding thread rolling carriage. Due to the fact that the encoder is mature and low in cost, the encoder is used as a position sensor for recording the sliding thread rolling supporting plate and is a good choice.

Example four:

the present embodiment is a modification of the above-described embodiments, and is a refinement of the above-described embodiments with respect to the thread rolling monitoring sensor. The thread rolling monitoring sensor described in this embodiment is a grating detector installed on the sliding thread rolling carriage and the fixed thread rolling carriage.

The grating is a very accurate position sensor, the position accuracy of less than 1 mm can be obtained by reading the grating, but the grating is directly arranged on the sliding thread rolling supporting plate, the accuracy is very accurate, but the cost of the grating sensor is higher.

Finally, it should be noted that the above is only used for illustrating the technical solution of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred arrangement, it should be understood by those skilled in the art that the technical solution of the present invention (such as the form of thread rolling machine, the form of material conveying process and the form of push rod, etc.) can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
