Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass processing lathe, and more particularly to a one-side chuck glass processing lathe.

In general, glass processing lathes have very complex mechanisms and require precision due to their mechanical characteristics, so the main body of the machine tends to be large. Therefore, manufacturing and maintenance are difficult, operation is complicated, and manufacturing costs are high. With conventional glass processing lathes, large and expensive lathes had to be used even for very small-scale work, regardless of the type of work.

Further, although a typical glass processing lathe is equipped with chucks on both sides of the device as shown in FIG. 4, one chuck is sufficient for many operations depending on the type of lathe processing work.

Therefore, the purpose of this invention is to provide a one-sided chuck type glass processing lathe that solves the above problems without losing the original function of the lathe, is small, and prevents chuck rotational vibration, which is most important in glass lathe processing. shall be.

To achieve this objective, the glass processing lathe of the present invention has at least one bearing in the body,
It consists of a main shaft to which a tip chuck is attached, and a support stand equipped with a pair of shafts that can rotate horizontally and in parallel to rotatably support this main shaft, and one of the shafts is connected to a motor. The shaft has at least two pulleys that contact the main shaft, and a pulley that meshes with a guide groove at the tip of the main shaft, the other shaft has at least two pulleys that contact the main shaft, and the bearing in the body of the main shaft is an elastic body. It is characterized in that it is fixed to the bottom of the support base via.

Hereinafter, the present invention will be described in detail based on the embodiments shown in the accompanying drawings.

In FIG. 1, the glass processing lathe according to the present invention consists of a main shaft 1 and a support base 2 that supports and rotates the main shaft.

The main shaft 1 is installed horizontally in the axial direction between a pair of shafts 3 and 4 that are horizontally arranged in parallel on a support base 2.
It is held in contact with a total of four pulleys 6, 7, 9, and 10 that are spaced apart from each other on the shafts 3 and 4, and rotates as the rotational motion of the drive shafts 6 and 7 is transmitted via the pulleys 6 and 7. A bearing 11 that receives a radial load is attached to the body of the main shaft 1, and the bearing 11 is connected to an elastic body 12 fixedly installed on a support base 2 in order to adjust vibration in the radial direction.
Stable rotation of the main shaft is ensured. Furthermore, a guide groove 13 is formed at the tip of the main shaft 1 to receive a thrust load.
By fitting the pulley 8 of the shaft 3 into the shaft 3, vibration of the chuck 14 in the thrust direction is completely prevented.

As described above, a pair of horizontal shafts are rotatably arranged in parallel on the support base 2. A pulley 5 connected to a motor is fixed to the rear end of one shaft 3, and rotates the shaft 3. Main shaft 1
The pulleys 6 and 7, which abut and support the shaft 3 from the lower side, rotate as the shaft 3 rotates, causing the main shaft 1 to simultaneously rotate due to frictional action. The pulley 8 attached to the tip of the shaft 3 is an idle pulley,
Since it is fitted into a guide groove formed at the tip of the main shaft 1, it rotates as the main shaft 1 rotates.

A pulley 9 installed at a distance on the other shaft 4,
Reference numeral 10 denotes an idling pulley which abuts and supports the main shaft 1 from the lower side surface and rotates simultaneously with the main shaft 1, thereby smoothing the rotation of the main shaft 1.

The glass processing lathe of the present invention has the following effects.

Since the support base is structured to support the main shaft and also transmit power, the device can be made smaller and lighter, and is movable, that is, easily transported.

Since the structure of the support stand and the main shaft is simple, manufacturing and maintenance are easy, and costs thereof are reduced.

The idling pulley connected to the tip of the drive shaft engages with the groove formed at the tip of the main shaft and rotates at the same time, preventing the chuck from wobbling in the thrust direction, which is most important for glass processing. Since the bearing holding the chuck is fixed to the support base by an elastic body, stable rotation without waste is enabled to prevent the chuck from wobbling in the radial direction.

In this way, the mechanism of the device is simple and compact, and the shake prevention is ensured, making it easier to operate, improving work efficiency, and expanding the scope of use. For example, it can be used for glass flanges, glass duers, glass joints, etc. from small-scale glass processing to large-scale glass processing.
