Description
Technical field
The present invention relates to printed circuit board (PCB) (PCB) boring machine, particularly relate to the cylinder buffering device of drilling machine of printed circuit board.
Background technology
As shown in Figure 1 to Figure 3, existing apparatus includes spindle assemblies 1 and presser foot component 2, and spindle assemblies 1 includes motor 11, is positioned at the cylinder 12 below motor 11 and main shaft 13.Main shaft 13 is connected with cutter 131.Presser foot component 2 includes presser feet cover 21, is positioned at the presser feet 22 below presser feet cover 21 and is positioned at the piston rod 23 coordinated with cylinder 12 above presser feet cover 21.Cutter 131 may pass through presser feet cover 21 and presser feet 22 thus sheet material 3 is holed.The effect of presser feet 22 be before boring compacting holed near sheet material 3, thus ensureing drilling quality.It is unlikely to time simultaneously for ensureing pressing plate to damage cutter 131, it is desirable to when presser feet 22 compacting sheet material 3, point of a knife indentation presser feet certain distance.When piston rod is positioned at cylinder bottom, this segment distance is to be determined by the physical dimension of piston rod 23, presser feet cover 21 and presser feet 22.When, after the processed sheet material 3 of presser feet 22 compacting, motor 11 continues to drop to drilling depth, now, motor 11 causes piston rod 23 upwards relative motion in cylinder 12 to bottom offset, so that piston rod 23 and cylinder bottom 121 produce certain distance.After being drilled the setting hole degree of depth, quickly upwards, now motor 11 downward force disappears motor 11, piston rod 23 moves relatively downward, comes back to cylinder bottom 121, and This move can make piston rod 23 clash into cylinder 12, produce the noise of relatively high-decibel, simultaneously shortening cylinder service life.And adopting the cylinder 12 with cushioning effect can increase cylinder dimensions, cylinder cost also can improve simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of cylinder buffering device that can relax when cylinder size is constant and clash between piston and cylinder.
Correspondingly, a kind of cylinder buffering device of the present invention, including spindle assemblies and presser foot component, described spindle assemblies includes motor, is positioned at the main shaft below motor and is positioned at the cylinder of main shaft both sides, described spindle assemblies is provided with the second Buffer Unit, has cutter below main shaft；Described presser foot component includes presser feet cover, is positioned at the piston rod above presser feet cover and is positioned at the presser feet below presser feet cover, at least one piston rod is provided with the first Buffer Unit, described first Buffer Unit can move axially along piston rod, the piston that described piston-rod end has is positioned at cylinder, when the point of a knife indentation presser feet of described cutter, the lower surface of described first Buffer Unit and the upper surface of the second Buffer Unit abut mutually, and the bottom surface that described piston and cylinder have keeps safe distance.
As a further improvement on the present invention, described second Buffer Unit is arranged on described main shaft.
As a further improvement on the present invention, described second Buffer Unit can move axially along main shaft.
As a further improvement on the present invention, the lower surface of at least the first Buffer Unit and the upper surface one of both of the second Buffer Unit are provided with cushion.
As a further improvement on the present invention, described cushion is nylon.
The invention has the beneficial effects as follows: reduce noise and extend the service life of cylinder.

Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments are not limiting as the present invention, those of ordinary skill in the art is all contained in protection scope of the present invention according to the made structure of these embodiments, method or conversion functionally.
As shown in Figure 4 and Figure 5, cylinder buffering device of the present invention includes spindle assemblies 10 and presser foot component 20.Described spindle assemblies 10 includes motor 101, is positioned at the main shaft 102 below motor 101 and is positioned at the cylinder 103 of main shaft 102 both sides.Cylinder 103 and main shaft 102 can move up and down with motor 101, spindle assemblies 10 is provided with the second Buffer Unit 105, preferably, second Buffer Unit 105 is arranged on main shaft 102, the lower end of main shaft 102 has cutter 104, second Buffer Unit 105 can move axially along main shaft on main shaft 102, after arriving a certain position, then tightens together with main shaft.
Described presser foot component 20 includes presser feet cover 201, is positioned at the piston rod 202 above presser feet cover 201 and is positioned at the presser feet 203 below presser feet cover 201.At least one piston rod 202 is provided with the first Buffer Unit 204, and similarly, the first Buffer Unit 204 can move axially along piston rod 202, after arriving a certain position, then tightens together with piston rod.After spindle assemblies 10 and presser foot component 20 assemble, the piston 205 of piston rod 202 end is positioned at cylinder 103；The lower surface 206 of the first Buffer Unit 204 and the upper surface 106 of the second Buffer Unit 105 abut against；Cutter 104 is positioned at presser feet 203 and point of a knife retraction presser feet 203 certain distance through presser feet cover 201.In the present embodiment, piston 205 and cylinder 103 bottom surface 1031 keep safe distance a.
When needing to hole, motor 101 moves downward, and band dynamic air cylinder 103, main shaft 102 move downwardly together, and the first Buffer Unit 204 and the second Buffer Unit 105 are separated from each other.Now, cutter 104 highlights presser feet 203 and begins at boring on sheet material 30；Piston 205 becomes big with the distance of cylinder 103 bottom surface 1031, causes that the air pressure above piston 205 becomes big.After boring, whole spindle assemblies 10 moves upward under driven by motor, until the first Buffer Unit 204 abuts again with the second Buffer Unit 105.Now, piston 205 returns to cylinder bottom surface 1031 apart from the position for a, and tool nose is retraction presser feet 203 certain distance again.
So, the distance of the point of a knife retraction presser feet that piston in prior art is determined by the present invention when cylinder basal surface position changes into the distance of the point of a knife retraction presser feet determined when mutually abutting when the first Buffer Unit and the second Buffer Unit, the shock of piston Yu cylinder is transferred on the first Buffer Unit and the second Buffer Unit, thus extending the service life of cylinder.
In present embodiment, the lower surface 206 of the first Buffer Unit and have cushion on the upper surface 106 of the second Buffer Unit, such as nylon, it is possible to absorbs and clashes into the impact produced, and reduces noise.Certainly, it is possible to only in the first Buffer Unit and the second Buffer Unit arranges cushion.
Meanwhile, for different demands, the distance of point of a knife retraction presser feet can change, now, at least one in removable first Buffer Unit, the second Buffer Unit, realize point of a knife retraction presser feet distance this function of adjustable.
It is to be understood that, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should be made as a whole by those skilled in the art, technical scheme in each embodiment through appropriately combined, can also form other embodiments that it will be appreciated by those skilled in the art that.
The a series of detailed description of those listed above is only for illustrating of the feasibility embodiment of the present invention; they also are not used to limit the scope of the invention, and all should be included within protection scope of the present invention without departing from the skill of the present invention equivalent implementations made of spirit or change.
