Description

Foam model perforating device

Technical Field

The utility model relates to a foam model punching device, and belongs to the field of casting.

Background

In full mold casting, due to the shape and structure requirements of the casting, punching operations are required to be performed on the foam model. Because most castings are single-piece customized products, the requirements on hole positions, quantity and size on the foam model are different, the punching of the foam model is generally performed by manual operation, namely, workers hold electric drills to perform punching processing. The manual punching is easy to cause insufficient precision, such as deviation of hole position and hole depth, which can seriously cause the rejection of the model and even the casting, and has defects.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects, the utility model provides a foam model punching device, which adopts the technical scheme that:

the utility model provides a foam model perforating device, its includes the location cover and the pivot of punching, the interval is equipped with a plurality of location nails on the base of location cover, the top center department of location cover installs the bearing, the pivot of punching is installed on the bearing, the cutter installation head is installed to the bottom of the pivot of punching, install the tool bit on the cutter installation head, the depth control lock is installed to the upper segment of the pivot of punching, the upper end of the pivot of punching is installed on actuating mechanism.

Furthermore, the depth control lock comprises a locking sleeve and a locking bolt which are sleeved on the punching rotating shaft.

Furthermore, the driving mechanism is an electric drill, and the upper end of the punching rotating shaft is installed in a drill chuck of the electric drill.

Furthermore, a dial gauge is arranged on the punching rotating shaft.

Furthermore, the side wall of the positioning cover is provided with a perspective hole.

Compared with the prior art, the utility model has the beneficial effects that: the utility model carries out punching positioning and anti-slip through the positioning cover with the positioning nail, reduces the swing of the rotating shaft by installing the punching rotating shaft on the bearing, sets the punching depth through the depth control lock, and has the characteristics of high punching precision, good hole forming quality and high processing efficiency.

Drawings

FIG. 1 is a schematic structural view of the present invention, wherein the positioning cover is a half-sectional view.

Detailed Description

The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.

Example (b):

referring to fig. 1, a foam pattern perforating apparatus includes a positioning cover 1 and a perforating rotary shaft 2. A plurality of positioning nails 3 are arranged on the bottom edge of the positioning cover 1 at intervals, a bearing 4 is arranged at the center of the top of the positioning cover 1, and perspective holes 9 are formed in the side wall of the positioning cover 1. The utility model discloses a drilling machine, including drilling pivot 2, cutter installation head 5, cutter installation head 6, the upper segment of pivot 2 is installed and is controlled the lock to the upper segment of drilling, and the lock is controlled including the cover to the depth control lock, and the upper end of pivot 2 that punches is installed in the drill chuck (not shown) of electric drill, drilling pivot 2 is equipped with the graduation apparatus (not shown), cutter installation head 5 is installed to the bottom of pivot 2 that punches, cutter installation head 5 is last to install the tool bit 6, the depth control lock is installed to the upper segment of pivot 2 that punches, and the lock is controlled the lock and is established at the lock sleeve 7 and the locking bolt 8 of the epaxial of drilling, the drill chuck (not shown) of electric drill is installed to the upper end of the pivot 2 that punches.

According to hole site design requirement, select the locking height of suitable tool bit and regulation depth control lock when using, press the nail with the position fixing cover in the foam model position of punching, start the electric drill and can not end down to the pivot of punching, the device has the characteristics that the precision of punching is high, the pore-forming is of high quality, machining efficiency is high.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
