Description

Vertical thread rolling machine

Technical Field

The invention belongs to the field of machining and manufacturing, and particularly relates to a vertical thread rolling machine.

Background

At present, the following three modes are mostly adopted for thread processing: the method comprises the steps of machining on a special thread rolling machine by adopting a thread rolling plate, rolling on the special thread rolling machine, and rolling on a numerical control or common lathe. The rolling machining on the thread rolling machine has the problems of complex machine tool adjustment and low machining precision, and the service life of the thread rolling plate is lower when high-strength threads are machined, so that the radial force applied to a workpiece during rolling is very large, and the rolling machine cannot be used for machining thin-wall parts. The special thread rolling machine has the advantages of large volume, complex structure maintenance, suitability for processing medium and large batch parts and low production efficiency compared with the thread rolling machine. The method has the advantages that the threads are rolled on the lathe, so that the method is rarely used in China at present, special rolling tools are needed, the production is rarely carried out in China, the limited processing range is limited by tools and materials, the cost is high, and the requirements on the skills of manufacturing workers are high. In conclusion, the parallelism requirements of the movable thread rolling plate and the fixed thread rolling plate are strictly ensured when the thread rolling machine is adjusted, and the thread rolling machine is basically applied to solid threads with lower precision under the influence of machining precision and radial force; after the mechanical and electrical integration of the thread rolling machine, the degree of automation is improved, the price is higher, and the thread rolling machine is more used in a large batch; the tool body used for lathe rolling is complex in manufacturing and debugging, and the imported products are poor after sale.

Disclosure of Invention

In view of the above, the invention provides a vertical thread rolling machine, which solves the problems of large volume and high processing cost of the existing equipment.

The technical scheme adopted for solving the technical problems is as follows: a vertical thread rolling machine comprises a cylindrical shell, wherein a motor, a speed changing device, an eccentric device, a disc, three cams, three universal joints and three rolling wheels are further arranged in the shell. The motor is connected with the speed changing device, the speed changing device is connected with the disc through the eccentric device, and the disc provides swing power for the three cams.

The three universal joints are arranged around the speed changing device, one end of each universal joint is arranged on the speed changing device, the rolling wheel is arranged at the other end of each universal joint, the cam can move along the inner wall of the shell, and a connecting shaft for driving the rolling wheel to move radially and back and forth is further arranged between the cam and the rolling wheel. When the motor drives the speed changing device to make the speed changing device drive the disc to swing back and forth through the eccentric device, the swing of the disc is transmitted to the cam, and under the action of the connecting shaft, the opening and closing actions of the three rolling wheels are completed, and the required threads are rolled out.

Further, still be equipped with the cooling liquid case in the casing, this cooling liquid case sets up between motor and speed change gear, still is equipped with a plurality of upwards extending cooling tube on the cooling liquid case, and the free end of this cooling tube is close to the rolling wheel and sets up.

Further, a button for controlling the motor to work is arranged outside the shell.

Further, the rolling wheel is detachable, so that the processing requirements of different thread types can be met.

The invention has the beneficial effects that:

1. The invention replaces partial thread rolling machine, thread rolling machine and special rolling tool, greatly reduces the volume of equipment, ensures the processing precision and efficiency, greatly reduces the processing cost, does not need other auxiliary tools, and is very convenient to debug.

2. The invention has a vertical structure, other thread rolling machines have a horizontal structure, the volume is greatly reduced, and the energy consumption and the weight are greatly reduced; in addition, the radial rolling pressure is small when the machine rolls, so that hollow threads which are difficult to process by other thread rolling machines can be rolled.

3. The invention has wide processing range, can clamp the workpiece manually, can process metric threads, english threads, pipe threads, american threads and the like by using one device, can manufacture rolling wheels with different sizes and specifications according to the requirements of different parts to match the processing sizes of the parts, and achieves the processing sizes and the functional requirements of the parts.

The invention will be described in more detail below with reference to the drawings and examples.
