Specifically, as shown in fig. 3, the sliding component 40 includes a slide way 41 fixed with the housing 11 and used for sliding a plastic cover 44, a blanking port 42 is formed on the inner wall of the slide way 41, and a collecting tray 43 is arranged below the blanking port 42.

Through setting up slide 41, slide 41 that the slope set up can keep the slip direction of plastic envelope lid 44, when drilling, can keep the drill bit 35 to run through the back and can not appear touching by blanking mouth 42 on the slide 41 to can drop the sweeps of drilling and collect in the tray 43 that gathers materials, the drilling can be with the sweeps discharge when reciprocal axial rapid movement, keeps downthehole smoother.

Because the plastic package is smaller, it is difficult to use the mode of drilling simultaneously with a plurality of drills 35 to process, therefore hole site calibration and drilling in proper order are required one by one, further reducing the processing efficiency and increasing the risk of mistakes. The displacement assembly 20 is driven to be pressed downwards through the deflection of the pull plate 14, so that the positioning assembly 50 is matched with the positioning cover 55 through the inserting rod 51 to fix and accurately position the plastic sealing cover 44. The drill bit 35 accurately completes machining of a first drilling position under the guidance of the path plate 12, and meanwhile, the drill bit is automatically adjusted to a second drilling position and a third drilling position, so that high-precision positioning of multi-hole site machining is realized, and deviation caused by manual multi-positioning is avoided.

The electric clamp 33 of the automatic equipment and the automatic drill can be coordinated to ensure the machining precision and efficiency, but in the manual operation, if clamping and drilling are controlled simultaneously, the coordination is difficult, the working strength of workers is obviously increased, and the operation efficiency and stability are reduced. In the scheme, after the plastic sealing cover 44 sliding in the slide way 41 is blocked by the positioning cover 55, the positioning is performed once, when the positioning cover 55 is pressed down, the positioning cover 55 is positioned twice under the action of the flaring at the lower part, so that the positioning cover is aligned with the inserted rod 51, the inserted rod 51 passes through the positioning cover for three times, the positioning accuracy is ensured, and after the positioning cover is positioned for three times, the positioning cover 55 presses the plastic sealing cover 44 under the pressure of the positioning spring 54, and the final pressing after the positioning cover is positioned for three times is kept.

When the plastic sealing cover 44 is used, firstly, the plastic sealing cover 44 is sequentially placed on the slide way 41 in a designated direction, the plastic sealing cover 44 slides down and is blocked by the inserting rod 51, after the plastic sealing cover 44 is sequentially placed, the pulling plate 14 is lifted, the pulling plate 14 is kept to move upwards along with the top plate 21, the top plate 21 is matched with the top head 314 with the displacement assembly 20 through the slide rail 26 and the sliding piece 312 to slide to the horizontal height of the reset groove 124, the inserting rod 51 is moved upwards at the moment, the plastic sealing cover 44 is blocked by the positioning cover 55, the driver 22 is started, the driver 22 is rotated along with the driven gear 34 through the driving gear 23 and the gear cylinder 53, the driven gear 34 is rotated along with the drill bit 35 through the clamp 33, when the pulling plate 14 deflects, the end part of the pressing plate 25 is moved transversely in the through hole 15, the pressing plate 25 is kept to only axially move along with the top plate 21, the top plate 21 is directly penetrated through the inserting rod 51 to penetrate the plastic sealing cover 44, the plastic sealing cover 44 is positioned, and the positioning spring 54 is continuously compressed and the positioning cover 55 is kept to press the plastic sealing cover 44;

In the pressing process, the top plate 21 slides in the rightmost guide groove 122 with the top 314, when the top 314 moves to a certain distance, the top 314 slides into the bottom of the displacement groove 123 under the action of the elasticity of the top spring 315, the depth of the bottom of the displacement groove 123 is larger than that of the guide groove 122, the top of the displacement groove is consistent with the depth of the guide groove 122 to form an inclined plane, and the displacement groove 123 is continuously blocked in the pressing process and then axially moves;

When the drill bit 35 is continuously pressed down, the drill bit 35 contacts the plastic cover 44 and drills holes in high-speed rotation, the drilling speed is different based on the thickness or the difference of materials of different plastic covers 44, if the materials are harder to penetrate, the greater the blocking force of the drill bit 35 is, the greater the resistance is, the greater the blocking force of the drill bit 35 is, the greater the deformation amount of the two retaining springs 324 is, the pressure on the drill bit 35 is increased, after the drill bit 35 penetrates, the instantaneously lost pressure enables the retaining springs 324 to rebound back and forth, the drill bit 35 reciprocates in a detection hole, the adaptation of the inner wall of the drill bit is maintained, and when the detection hole is separated from the drill bit 35, the pressure of the positioning spring 54 on the positioning cover 55 is also reduced.

When the top plate 21 is reset and moves, the top 314 slides in the displacement groove 123, firstly slides axially for a certain distance and then slides obliquely, and simultaneously slides on the slide rail 26 with the slide piece 312 on the connecting plate 311, so that the drill bit 35 slides out of the detection hole and then moves horizontally until being positioned in the other guide groove 122;

After the drilling is finished, the plug 314 slides into the reset groove 124, and at the moment, the plug 314 transversely slides in the reset groove 124 to realize reset based on the clockwise inertia force under the high-speed engagement of the rotation of the gear cylinder 53 and the driven gear 34;

Because a plurality of Hall elements are distributed in the plastic package body, a plurality of point positions with the same radius are required to be accurately perforated. However, the existing method mainly relies on manual cooperation with semi-automatic equipment to finish processing, and the mode is low in cost, but certain difficulties exist in maintaining accurate positioning when processing small plastic package bodies, deviation easily occurs in manual repeated positioning, and hole position deviation or inaccuracy is caused.

According to the scheme, through the fixed movement track of the path plate 12, the accurate positioning and drilling operation of a plurality of positions of the drill bit 35 are carried out, the problem that deviation occurs easily in positioning in the post-processing process, hole position deviation or inaccuracy is caused is solved, intelligent control is not needed in the whole, the requirement on operators is low, and the operation steps are simple and the operators get on hand faster.

Especially in the trompil processing of less body type plastic envelope body, manual positioning accuracy is difficult to ensure, shelters from hall element because of the hole site skew easily, influences detection accuracy and product yields. Furthermore, conventional approaches add to the complexity and uncertainty of the process by multiple manual positioning operations. The whole operation process of this scheme promotes the arm-tie 14 promptly for after the control personnel stimulate many times can realize the accurate location shaping of a plurality of detection holes, and easy and simple to handle, the processing precision is high, and efficiency is ensured.
