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

Detailed Description

The first embodiment is as follows:

the present embodiment is an electric drive for a sliding thread rolling carriage of a thread rolling machine, as shown in figure 1. The embodiment comprises the following steps: and the sliding thread rolling carriage 3 is arranged on the lathe bed 1 and matched with the fixed thread rolling carriage 2, and the sliding thread rolling carriage is connected with an electric driving component 4 for driving the sliding thread rolling carriage to do reciprocating motion.

In the embodiment, the fixed thread rolling carriage and the sliding thread rolling carriage form a thread rolling station 5, and a workpiece 7 is pushed into the thread rolling station from a material tank 8 by a push rod 6 to be subjected to thread rolling processing. The conventional sliding thread rolling carriage usually adopts a crank-link mechanism to convert the rotary motion of a motor into the linear reciprocating motion of the sliding thread rolling carriage. The transmission crank connecting rod is provided with a flywheel and a crank connecting rod which are large in diameter generally for enabling the rotation to be stable, the whole system is complex and prone to failure, and due to the effect of the flywheel, after the motor is powered off, the flywheel can continue to rotate under the effect of inertia, and the thread rolling carriage cannot stop immediately. This inertia tends to affect the quality of the control thread. The embodiment eliminates the traditional crank connecting rod mechanism, replaces the traditional crank connecting rod mechanism by electric drive, greatly simplifies the structure and enhances the control capability of thread rolling quality.

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 drive motor of the electric drive means may be a servo motor or a stepping motor. The servo motor or the stepping motor is used for driving the electric driving component to enable the thread rolling process to be controlled accurately to be very simple, an electronic digital control device such as an industrial computer can be directly adopted for control, feedback control through sensors such as an encoder is not needed, an ideal effect can be achieved, and if the sensors are used for monitoring the sliding thread rolling carriage, more accurate control can be achieved through negative feedback.

When the sliding thread rolling carriage needs to be accurately controlled, the grating can be arranged on the sliding thread rolling carriage, the accurate position of the sliding thread rolling carriage is collected, the sliding thread rolling carriage is controlled to have the precision of less than 0.1 mm through a thread rolling machine controller, and high-precision thread machining is achieved.

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 embodiment, and is a refinement of the above-described embodiment with respect to the electric drive member. The driving motor used by the electric driving component in this embodiment is a stepping motor or a servo motor, and the stepping motor or the servo motor is electrically connected with the thread rolling machine controller.

Precise control can be achieved using servo motors or stepper motors. The thread rolling machine controller is not a common electric appliance controller, but an electronic device with digital storage and calculation capabilities, such as an industrial control computer, a single chip microcomputer, a single board computer, an embedded system or a PLC (programmable logic controller). If the feeding device is also electrically driven, the operation system and the control system of the whole thread rolling machine can be very simple, so that the complexity of the whole thread rolling machine is greatly reduced, the reduction of the complexity means the reduction of the fault probability, and the use cost and the maintenance cost of equipment are saved.

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 machine controller. The thread rolling machine controller described in this embodiment is connected to thread rolling monitoring sensors installed on the fixed thread rolling carriage and the sliding thread rolling carriage.

The thread rolling monitoring sensor is installed to monitor the accurate position or the processing state of the sliding thread rolling carriage. The thread rolling monitoring sensor can be one sensor or a sensor system consisting of a plurality of sensors, for example, a grating is adopted to monitor the position of the sliding thread rolling carriage, a strain sensor is utilized to monitor the stress state of the thread rolling carriage during processing, and the like, and then the obtained data is input into an electronic digital computing device to be analyzed and calculated to form the control of the sliding thread rolling carriage so as to control the whole machine.

Example five:

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.

Since the grating detector is a very accurate position sensor, the use of this sensor can achieve control accuracy below 0.1 mm.

Finally, it should be noted that the above is only used for illustrating the technical solutions 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 solutions of the present invention (such as the form of the thread rolling carriage, the form of the electric driving device, and the form of the thread processing process, etc.) can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
