Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
Furthermore, in the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1, one of the purposes of the present invention is to provide an aluminum alloy punching device capable of adjusting the punching depth based on sliding, comprising a workbench 100 and a top plate 101 arranged on the top of the workbench 100 through a support column, wherein an air cylinder 102 is installed on the top of the top plate 101, and the movable end of the air cylinder 102 penetrates through the top plate 101 and is fixedly connected with a mounting plate 103; in the punching process, at least two tool bits 105 with different diameters are needed in the concentric hole, so that at least two driving pieces 104 are installed at the bottom of the mounting plate 103, the driving pieces 104 preferably adopt motors, and the output end of each motor is connected with the tool bit 105 with different diameters. When the cutter head is in operation, a workpiece is placed below the cutter head 105, and the movable end of the air cylinder 102 extends downwards to drive the mounting plate 103, the driving piece 104 and the cutter head 105 to move downwards, so that the cutter head 105 is in contact with the workpiece, and cutting of the workpiece is completed.
However, during the second perforation of the concentric holes, the chips generated during the perforation remain in the holes of the first perforation or remain between the two holes, which is not beneficial to subsequent processing. To this end, referring to fig. 1, the top of the table 100 is provided with a workpiece carrier 120 and a guide mechanism 110, wherein:
the workpiece carrier 120 is used for fixing a workpiece;
The guide mechanism 110 is located directly below the plurality of tool tips 105 for guiding the work carrier 120 under the plurality of tool tips 105; the portion of the guide mechanism 110 between each two tool tips 105 then has a guide portion that is angled such that when the work piece carrier 120 is moved to the guide portion, the work piece carrier 120 is flipped over to drive the work piece to eject debris from the hole due to the angled effect.
That is, during the process of moving the workpiece from the first tool bit 105 to the second tool bit 105, the guiding portion guides the workpiece to an inclined state, so that chips in the hole on the workpiece automatically fall off under the action of gravity, the hole is always in a cleaner state, and the subsequent processing efficiency is improved.
As shown in fig. 2, the guiding mechanism 110 includes side plates 111 fixedly disposed on two sides of the top of the guiding mechanism 110, the side walls of the side plates 111 are provided with rail grooves 130, the rail grooves 130 are in a state of being in a height fluctuation, and mainly comprise three parts, including a top rail 131 located above the side walls of the guiding mechanism 110, a bottom rail 132 located below the side walls of the guiding mechanism 110, and a guiding part located between the top rail 131 and the bottom rail 132; the guide portion is a ramp 133, and the connection between the end of the ramp 133 and the top rail 131 and bottom rail 132 is preferably filtered by an arc bend to allow smooth passage of the workpiece carrier 120. The bottom end of the inclined rail 133 is inclined toward the middle of the head rail 131. This way the hole is directed towards the bottom when the workpiece is located there. The side walls of the side plates 111 are then also provided with traction members for drawing the work piece carrier 120 under the plurality of tool tips 105.
As shown in fig. 3, the workpiece carrier 120 includes a carrier plate 121, rotating wheels 122 penetrating into the track grooves 130 are rotatably disposed on two sides of the carrier plate 121, and the diameter of the rotating wheels 122 is smaller than the height of the track grooves 130, so as to avoid the phenomenon that the rotating wheels 122 cannot rotate due to the fact that the top and the bottom of the rotating wheels 122 are simultaneously contacted with the top and the bottom of the track grooves 130. Secondly, the top of loading board 121 is provided with the fixed part, including fixing the locating plate 126 at loading board 121 top one end to and slide the push pedal 127 that sets up at loading board 121 top, the one side rotation that push pedal 127 kept away from locating plate 126 is connected with threaded rod 128, threaded rod 128 threaded connection is in one side of loading board 121. In this way, in the drilling process, the workpiece is placed on the top of the bearing plate 121, and then the threaded rod 128 is rotated, so that the threaded rod 128 pushes the push plate 127 to move towards the positioning plate 126, and the workpiece on the top of the bearing plate 121 is clamped, so that the fixing effect on the workpiece is realized.
In addition, for some highly precise work pieces, the work piece is held on top of the carrier plate 121, but the force generated by the rotation of the tool bit 105 is very likely to cause displacement of the carrier plate 121 at the top rail 131. For this purpose, in fig. 3, a slot 124 is formed at one end of the top of the carrier 121, and a positioning rod 125 is longitudinally inserted into the slot 124 in a sliding manner, and the positioning rod 125 is fixedly disposed on the top of the mounting plate 103. Meanwhile, the bottom end of the positioning rod 125 should be lower than the bottom end of the tool bit 105, so that the positioning rod 125 drills into the slot 124 before the tool bit 105 drills. Thus, when the mounting plate 103 drives the tool bit 105 to move downwards, the positioning rod 125 can also be inserted into the slot 124 along with the downward movement of the mounting plate 103, and at this time, the slot 124 cannot displace, so that the workpiece is sufficiently fixed in the punching process. The slot 124 is preferably a tapered structure with a large top opening and a small bottom opening, so that the positioning rod 125 guides the carrier plate 121 directly under the cutter head 105 through the inclined surface of the side wall of the slot 124 even when the carrier plate 121 is not directly under the cutter head 105.
As shown in fig. 4, the traction member includes a guide tube 140 fixedly disposed at one side of the side plate 111, the guide tube 140 has the same shape as the track groove 130, and the guide tube 140 is communicated with the track groove 130 through a channel formed in the side wall of the side plate 111, an elastic rope 141 is slidably disposed in the guide tube 140, a straight rod 123 connecting one end of the elastic rope 141 and the side wall of the bearing plate 121 is disposed between the two side walls, and the straight rod 123 is slidably disposed in the channel formed in the side wall of the side plate 111.
Working principle:
The work piece is fixed on the top of the bearing plate 121, the movable end of the air cylinder 102 extends downwards to drive the mounting plate 103, the driving piece 104, the tool bit 105 and the positioning rod 125 to move downwards, in the process, the positioning rod 125 is firstly inserted into the slot 124 to fix the bearing plate 121, and then the tool bit 105 moves downwards to the work piece on the top of the bearing plate 121 to drill the work piece.
After the first drilling is finished, one end of the elastic rope 141 is pulled, so that the other end of the elastic rope 141 pulls the bearing plate 121 to move in the track groove 130 through the straight rod 123, and then as shown in fig. 5, when the bearing plate 121 moves to the bottom rail 132, the bottom rail 132 is in an inclined state, so that the bearing plate 121 is forced to overturn, the hole on the surface of the workpiece is downward, and chips in the hole are poured out.
Furthermore, as shown in fig. 2, in the present embodiment, the heights between the plurality of head rails 131 are different from each other. When the bearing plate 121 is moved to each top rail 131, the distance between the workpiece at the top of the bearing plate 121 and the tool bit 105 is changed, so that the drilling of the depth of the workpiece at different positions is realized in the process that the tool bit 105 is also moved downwards.
Considering that some smaller chips are adsorbed to the side wall of the hole, it is difficult to pour out the adsorbed chips even if the work is tilted. To improve the efficiency of the falling of the chips from the holes, a shaking assembly for applying shaking force to the inclined carrier plate 121 is provided at the guide portion.
Fig. 2 illustrates one embodiment of a dithering assembly, as shown: the shaking unit is a plurality of protrusions 134 disposed at opposite sides of the ramp 133, and the protrusions 134 at one side are staggered with the protrusions 134 at the other side (particularly, as shown in fig. 2, the protrusions 134 at one side are located between the protrusions 134 at the other side), so that a moving channel for guiding the carrier plate 121 to perform an S-shaped movement is formed in the ramp 133. During the moving process, the bearing plate 121 makes frequent S-shaped movement in the inclined rail 133, so as to generate shaking, and the work piece on the surface of the bearing plate 121 is driven to shake by using the shaking force, so that the scraps in the hole are poured out under the dual actions of tilting and shaking.
Fig. 6 illustrates another embodiment of a dithering assembly, as shown: the shaking assembly is a bump 135 disposed at one side of the inclined rail 133, because the speed of the carrier 121 gradually increases when the carrier 121 moves from the top to the bottom of the inclined rail 133, so that the bump 135 is disposed near the bottom of the inclined rail 133, and when the carrier 121 moves to the bottom of the inclined rail 133, the bump 135 blocks the rotating wheel 122 moving at high speed, so that the rotating wheel 122 suddenly stops to drive the carrier 121 to vibrate, and chips in the hole are vibrated out. And a gap for passing the runner 122 is provided between one end of the projection 135 and the ramp 133, so that the decelerated runner 122 can continue to move through the gap.
Therefore, by applying shaking force to the rotating wheel 122 in the inclined state, the chips in the holes are shaken out under the shaking action, so that the phenomenon that some smaller chips are adsorbed on the side walls of the holes and are difficult to separate is avoided.
In the above, the pulling of the elastic cord 141 may be driven by a motor, and the motor rotates to wind the elastic cord 141, so that the other end of the elastic cord 141 moves, thereby pulling the carrier plate 121 to move. In addition, the following structure may be employed. As shown in fig. 7 and 8:
One end of the elastic rope 141 is wound with a winding roll 150, the winding roll 150 is fixed at the top of the guide mechanism 110 through a bracket 151 connected with the end in a rotating way, a clamping groove 152 is formed in one side of the winding roll 150, a bolt 153 penetrates through the side wall of the bracket 151 in a sliding way, and one end of the bolt 153 is obliquely arranged and can penetrate into the clamping groove 152. The end coaxial coupling of take-up reel 150 has connecting axle 154, and the outer lane of connecting axle 154 is connected with ratchet 155, and the outer lane of ratchet 155 is provided with lantern ring 156, and the inner circle rotation of lantern ring 156 is provided with pawl 157, is provided with elastic piece 158 between one side of pawl 157 and the lantern ring 156 inner circle, and the laminating of the outer lane of lantern ring 156 has drive strip 159, and drive strip 159 is fixed to be set up in the bottom of mounting panel 103.
Working principle: when the mounting plate 103 moves downwards, the mounting plate 103 drives the driving rod 159 to move downwards, the driving rod 159 drives the sleeve ring 156 to rotate through friction force, the sleeve ring 156 rotates to apply pushing force to the ratchet wheel 155 through the pawl 157, the ratchet wheel 155 is forced to drive the winding roll 150 to rotate through the connecting shaft 154, and the winding roll 150 rotates to wind the elastic rope 141. In addition, during the downward movement of the mounting plate 103, the positioning rod 125 is inserted into the slot 124 to fix the bearing plate 121, so that the elastic cord 141 is wound at this time, and only the elastic cord 141 can be elastically stretched.
When the mounting plate 103 moves upwards, under the action of the ratchet 155 and the pawl 157, the driving bar 159 moves upwards to drive the collar 156 to rotate reversely, so that the power is not transmitted to the pawl 157, and the bolt 153 is inserted into the clamping groove 152 to fix the winding roll 150. Thus, when the mounting plate 103 is moved up, the positioning rod 125 moves up and out of the slot 124, and the elastic cord 141 pulls the carrier plate 121 to move to the other top rail 131 by elastic contraction at the first time. Thereby performing a second drilling operation.
In summary, by the cooperation between the downward movement of the mounting plate 103 and the elastic cord 141, when the carrier 121 is detached from the fixing, the elastic cord 141 pulls the carrier 121 to move to the other top rail 131 by elastic contraction at the first time. And the speed block of elastic shrinkage of the elastic rope 141 can increase the speed of the bearing plate 121 passing through the inclined rail 133, thereby increasing the shaking force of the bearing plate 121 on the inclined rail 133 and increasing the falling effect of the scraps.
In addition, as shown in fig. 9, a scraper 160 is fixedly connected to the bottom of the carrier plate 121, and when the carrier plate 121 moves in the bottom rail 132, the scraper 160 can scrape the chips at the bottom of the table 100 to a uniform place.
