The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

After power comes out of the main motors 1-4, the effect of integral speed reduction is achieved through the transmission belts 1-6 and the transmission gears 1-7. When power comes to the main shafts 1-5, the power is divided into 2 directions by the transmission bevel gears 1-8, one is transmitted to the upper part along the shaft to drive the geneva gear to do intermittent motion and utilize a deformation cam fixed on the main shaft to press the upper pressure plate to make the part clamping assembly move, and the other is to make the drilling machine do reciprocating feeding motion by the crankshaft connecting rod.

The part transportation assembly comprises a material tray 1-1 and an intermittent mechanism 1-2 which are connected, and the intermittent mechanism 1-2 is connected with the power assembly. As shown in fig. 5-6, the intermittent mechanism is a novel buffer structure and comprises a driven wheel 1-2-1, a pin shaft 1-2-2, a sleeve 1-2-3, a deep groove ball bearing 1-2-4, an outer tongue stop washer 1-2-5, a hexagon nut 1-2-6 and a driving wheel 1-2-7, wherein the driven wheel 1-2-1 is fixedly connected with a material tray 1-1, one end of the pin shaft 1-2-2 is contacted with the driven wheel 1-2-1 through the sleeve 1-2-3 and the deep groove ball bearing 1-2-4 in sequence, the other end is connected with the driving wheel 1-2-7 and is fixed through the outer tongue stop washer 1-2-5 and the hexagon nut 1-2-6, the driving wheel 1-2-7 is connected with the power assembly, the driven wheel 1-2-1 is a grooved wheel, and the pin shaft 1-2-2 slides in a radial groove of the grooved wheel.

During the drilling process, the working time of the drilling machine is intermittent. If the conveying mechanism of the ball objects moves continuously, part of the parts are conveyed away without being processed, so that the processed parts and the unprocessed parts are mixed together, and the later sorting workload is increased. The intermittent conveying of parts is realized through the design of intermittent mechanism to this device, makes drilling and transportation reach the cooperation on the intermittent time. The intermittent mechanism of the device is a geneva mechanism, one or more pin shafts can be designed, so that the movement interval can be changed according to actual requirements, the intermittent mechanism has the advantages of simple structure, accurate turning and high mechanical efficiency, the processing speed is 20-50 times per minute, and the aim of continuous production can be fulfilled.

In the embodiment, the actual condition is considered to be the processing efficiency of 20 times per minute, the grooved wheel is designed to be of a one-pin four-groove type, before the pin shaft 1-2-2 connected with the driving wheel 1-2-7 enters the radial groove on the grooved wheel, the convex locking arc 1-2-9 locks the concave locking arc 1-2-8, and the grooved wheel is still; when the pin shaft 1-2-2 enters the radial groove, the convex locking arc and the concave locking arc are just separated, and the pin shaft 1-2-2 can drive the grooved pulley to rotate; when the pin shaft 1-2-2 is separated from the radial groove, the convex locking arc locks the concave locking arc, so that the grooved wheel is still. Therefore, when the driving dial rotates continuously, the grooved wheel is driven to rotate intermittently in a single direction, as shown in fig. 5, so as to drive the material disc 1-1 to rotate intermittently.

In order to ensure that the pin shaft 1-2-2 generates larger impact when contacting with the driven wheel 1-2-1, thereby prolonging the service life of the pin shaft, as shown in figure 6, the pin shaft 1-2-2 of the device utilizes a sleeve 1-2-3 to fix a deep groove ball bearing 1-2-4 at the position contacting with the driven wheel in the installation process, the contact of the pin shaft and the driven wheel is rolling friction, and the other end of the pin shaft is screwed by an outer tongue stop washer 1-2-5 and a hexagon nut 1-2-6, so that the falling and the deviation of the pin shaft can be prevented, and the expected movement target can be reached. If in the actual processing requirement, when the processing efficiency needs to be adjusted, the processing efficiency is realized by replacing driven wheels with different groove numbers and installing different numbers of shifting pins on the driving wheels (1-2-7).

The distance between the upper dead point and the lower dead point of the deformation cam 2-3 is smaller than the distance between the upper pressure plate and the material tray when the upper pressure plate does not work.

The upper pressing plate 2-1 and the material tray 1-1 are oppositely provided with a plurality of pairs of rubber gaskets for placing parts, and the function of guiding ball parts can be achieved. In this embodiment, the number of the rubber gaskets is 4.

The spring recovery structure 2-4 is provided in plurality, and each spring recovery structure 2-4 comprises a spring and an inner spring guide rail 2-6. When the spring recovery structure is designed, the material, the effective number of turns and the diameter of the spring steel wire of the spring are selected by calculating the dead weight of the upper pressure plate. Common spring materials include carbon spring steel, low manganese spring steel, silicon manganese spring steel, chrome vanadium steel, and the like. In the embodiment, the silicon-manganese spring steel is adopted, and the steel can obviously improve the elastic limit and improve the tempering stability due to the addition of silicon, so that the steel can be tempered at higher temperature to obtain good mechanical properties.

In order to conveniently carry out timely row material to the material bits at the drilling in-process, leave certain space between material dish and rubber gasket, the space communicates with external environment, no matter is through artifical clearance regularly or mechanical type gas-liquid wash all provides very big convenience.

When the ball body enters the step of drilling in the material tray, the ball body must be in a clamping and positioning state, and meanwhile, the clamping time and space are limited, so that the smooth drilling can be ensured. In the device, when the upper pressure plate 2-1 is pressed down, the ball parts are arranged between the gaskets, a certain friction force is generated under the action of pressure, and the size of the rubber gasket can be changed to meet the requirements of balls with different diameters. And the movement of the upper press plate 2-1 is realized by the movement of the deformation cam 2-3 above the upper press plate. When the deformed cam 2-3 moves to the top dead center, the pressure plate is pressed downwards, and the part is clamped; when the cam 2-3 moves to the bottom dead center, the pressure plate is lifted again under the action of the spring restoring structure 2-4. After a series of continuous movements, the parts are drilled, the upper pressure plate 2-1 is separated from the material tray 1-1, and then the next part is turned over. The upper pressure plate is enabled to be not closed up and down under the non-working state by means of the matching of the spring and the spline structure, so that parts can have enough space to enter the material tray from the material barrel, and when the upper deformation cam 2-3 rotates to the working area, the deformation cam 2-3 presses the upper pressure plate 2-1.
