Fig. 1A and fig. 1A-1 are schematic perspective views of the hole forming device 5 of the present invention applied to a processing apparatus 1. As shown in fig. 1A and 1A-1, the processing apparatus 1 includes: a transportation device 1a, a milling height device 2, an edge milling device 3, a turnover device 4 and the hole forming device 5.

In the present embodiment, the processing apparatus 1 defines the direction of the production line as the left and right directions (as indicated by the arrow Y), the direction perpendicular to the production line as the front and rear directions (as indicated by the arrow X), and the height direction along the processing apparatus 1 as the up and down directions (as indicated by the arrow Z). It should be understood that this orientation is used to illustrate the configuration of the present embodiment, and is not particularly limited.

The transportation device 1a is used for transporting (e.g. clamping) the object 9 to a processing position of a desired production line, so that the transportation device 1a is disposed at a position above and around the object 9, such as the height milling device 2, the edge milling device 3, the turnover device 4 and the hole forming device 5, so as to facilitate the object 9 to be placed on the height milling device 2, the edge milling device 3, the turnover device 4 and/or the hole forming device 5.

In the present embodiment, as shown in fig. 1B, the transportation device 1a includes at least one pick-and-place assembly 10 and a supporting assembly 11 movably erecting the pick-and-place assembly 10, so that the pick-and-place assembly 10 is used for picking and placing the target 9, and the pick-and-place assembly 10 is moved to move the target 9 in cooperation with the supporting assembly 11. For example, the supporting assembly 11 is a frame structure having two sets of door-shaped frames 110 erected on two opposite sides of a base surface (e.g. a floor), and a cross beam 111 spanning between the frames 110, wherein the cross beam 111 is located above the milling height device 2, the edge milling device 3 and the turning device 4 to serve as a displacement path of the pick-and-place assembly 10.

Furthermore, the pick-and-place assembly 10 includes a clamping portion 10a having the clamping member 100 and a supporting portion 10b for supporting the clamping portion 10a. For example, the width D of the clamping unit 100 of the clamping unit 10a can be adjusted as required to clamp the target object 9 with different widths, the distance between the two clamping units 10a can be controlled by using a hydraulic cylinder or a pneumatic cylinder (which is used as a power source 10D) to clamp or release the target object 9, and the carrying unit 10B is a moving frame which is vertically mounted on the cross beam 111 (e.g. on the limiting unit 112 of the cross beam 111) and pivotally connected to a gear (not shown) which is engaged with a rack 112a (as shown in fig. 1B-1) and moves linearly on the rack 112a by a driving force, so that the pick-and-place assembly 10 can move linearly back and forth in the arrow direction Y on a sliding base (e.g. the carrying unit 10B) and a sliding rail assembly (e.g. the limiting unit 112 and the rack 112a and the gear thereon). Specifically, the clamping unit 10a drives the clamping members 100 to extend or retract (in the direction of arrow Y) by a plurality of power sources 10d (such as pneumatic or hydraulic cylinders shown in fig. 1B) to generate an opening or clamping action, and an extension structure 101 connected to the clamping unit 10a is disposed at the bottom of the carrying unit 10B to lift the clamping unit 10a. Preferably, a motor (not shown) for driving the carrying portion 10b to move is disposed above the carrying portion 10b, so as to drive the gear to move linearly on the rack 112 a.

In addition, the number of the pick-and-place assemblies 10 can be set according to the requirement. For example, the pick-and-place assemblies 10 are respectively disposed at the processing positions corresponding to the milling height device 2, the edge milling device 3 and the turnover device 4, so at least two groups of pick-and-place assemblies 10 are provided. Specifically, each of the pick-and-place assemblies 10 is respectively disposed between the milling height device 2 and the edge milling device 3, and between the milling height device 2 and the turning device 4, and the pick-and-place assemblies 10 can be additionally disposed between the rod frame 110 and the edge milling device 3 as required, so that the plurality of pick-and-place assemblies 10 serve as intermediate transfer assemblies for the target 9, and the target 9 is continuously picked and placed at each processing position, thereby completing the processing flow of the whole production line.

For example, the target 9 is substantially rectangular (e.g. square), the bottom of the target 9 (e.g. the side of the second surface 9b, which is the bottom of the raised floor) is honeycomb-shaped, and the four corners of the second surface 9b of the target 9 are formed with the foot seats 90, so that the four foot seats 90 are provided with openings 900 (as shown in fig. 1D), and the four foot seats 90 are fixed on the supporting feet of the raised floor respectively by using screws. Specifically, the end surface 9d of the base 90 slightly protrudes (by the height difference h shown in fig. 1C-2) from the second surface 9b of the target 9, and a flange 91 protruding from the side surface 9C is formed on the edge of the first surface 9a, where the flange 91 is the four edges of the edge milling device 3 where the raised floor is to be machined. Since the object 9 of the present embodiment is a raised floor, the object 9 will be referred to as a raised floor hereinafter.

The milling device 2 is disposed in the middle stage of the processing flow of the whole production line, and cooperates with the transportation device 1a to move for processing the end surface 9d of the foot seat 90, for example, removing burrs from the end surfaces 9d of the four foot seats 90 of the raised floor, so as to process the height dimension required by the raised floor.

For example, the first positioning member 22 is a frame (e.g., a parallel frame as shown in fig. 2B), and a plurality of the milling height components 2a are disposed on two opposite sides (e.g., front and rear sides) of the first positioning member 22, and at least one fixing portion 220 (e.g., a corner cylinder clamp) can be disposed on the outer side of the two opposite sides of the first positioning member 22 as required. When in use, the corner cylinder clamps can be used as the fixing parts 220, which are correspondingly arranged on two opposite sides of the first positioning member 22 to press the target object 9 on the first positioning member 22, so that the raised floor is fixed on the first base platform 21, and at least one corner cylinder clamp is respectively arranged on one side of each of the first positioning members 22 to limit the raised floor to move and avoid deviating from the first positioning member 22 in the milling process; further, at least one stopping portion 220a may be disposed outside the first positioning member 22 and on the other side perpendicular to the side of the first positioning member 22 where the corner cylinder clamp is disposed, the stopping portion 220a blocks the side surface 9c of the raised floor, so as to facilitate an operator to place the target object 9 on the first positioning member 22 (e.g. in the direction of arrow Y1). It should be understood that the pick-and-place assembly 10 can also pick up the object 9 to be processed from a feeding position (located near the left side rod rack 110, not shown) and place the object on the first positioning member 22 at a processing position.

For example, based on one side of the second positioning member 32, the displacement direction (the moving direction f2, B2 shown in fig. 3B) of the second supporting structure 33 is perpendicular to the displacement direction (the moving direction f1, B1 shown in fig. 3B) of the rack seat 34. Specifically, a ball nut (not shown) and a ball screw (not shown) engaged with the ball nut are fixed on the lower side of the frame 34, so that the second motor 38b rotates the ball screw, and the ball screw rotates and does not move, so that the ball screw actuates the ball nut to generate a linear displacement, so that the ball nut linearly drives the frame 34 to displace along the rail 35, and the second milling cutter tool 30 is linearly displaced to a desired processing position.

The turnover device 4 is disposed between the height milling device 2 and the hole forming device 5 and cooperates with the transportation device 1a to turn over the first surface 9a or the second surface 9b of the target 9, for example, the raised floor with the burrs on the end surfaces 9d of the pedestals 90 removed is turned over so that the first surface 9a faces upward.

In the present embodiment, as shown in fig. 4A or fig. 4B, the flipping device 4 includes a third base 41, a shaft structure 40 disposed on the third base 41, a third positioning member 42 disposed on the third base 41, a third supporting structure 43 disposed on the third base 41 in a displaceable manner, and a driving member 47 disposed on the third base 41, and one end of the third positioning member 42 is pivotally connected to the shaft structure 40 to flip with respect to the third base 41, and the driving member 47 drives the third positioning member 42, so that the third positioning member 42 is forced to flip and is located above the third supporting structure 43, so that after the picking and placing assembly 10 places the target 9 on the third positioning member 42, the third positioning member 42 rotatably supports the target 9 on the third supporting structure 43.

Furthermore, at least one fixing structure 42a can be disposed on the front and rear sides of the third positioning member 42 as required to limit the displacement of the target object 9 and avoid the deviation from the third positioning member 42, and a propping structure 44 can be disposed on the third base 41 as required to prop up the other end side of the third positioning member 42. Specifically, the fixing structure 42a is pushed or pulled by an oil pressure cylinder (not shown), so that the fixing structure 42a is engaged with or disengaged from the third positioning element 42, and the fixing structure 42a abuts against or disengages the target object 9.

In addition, the third supporting structure 43 is a feeding plate, and a set of guide rails 45 is disposed on the third base 41 corresponding to the third supporting structure 43, so that the third supporting structure 43 can move between the third positioning member 42 and the hole forming device 5 along the guide rails 45. For example, a plurality of displacement portions 430 (e.g., sliders) are disposed on the bottom side of the third supporting structure 43, so that the plurality of displacement portions 430 engage the guide rail 45, and the third supporting structure 43 can move linearly along the guide rail 45 to move the third supporting structure 43 closer to or farther away from the third positioning element 42. Specifically, the third supporting structure 43 is pulled by an oil pressure cylinder (not shown), so that the third supporting structure 43 moves linearly along the guide rail 45.

In addition, the third positioning element 42 is a turnover plate, and the driving element 47 (as shown in fig. 4A) is disposed on the front side or the rear side of the third base 41 to drive the third positioning element 42 to turn over. For example, the driving member 47 includes a gear 471 and a rack 470 (as shown in fig. 4B), the rack 470 engages with the gear 471, and the gear 471 is coupled to the shaft 401 of the axle structure 40, so that when the rack 470 moves linearly, the gear 471 is driven to rotate, such that the gear 471 rotates the shaft 401 to flip the third positioning member 42 over the third supporting structure 43. Specifically, a push-pull rod 480 of a power pack 48 (e.g., a pneumatic or hydraulic cylinder) drives the rack 470 to linearly advance and retract, so as to rotate the gear 471. Preferably, at least one limit switch 49 is disposed on the third base 41 to control the extension/contraction distance of the push-pull rod 480, so that the rack 470 drives the rotation range of the gear 471 to stably turn over the third positioning element 42.

The hole forming device 5 of the present invention cooperates with the turning device 4 to form at least one hole 900 (a counter bore as shown in fig. 1D) on the first surface 9a of the target 9, for example, a hole is drilled at the foot seat 90 of the raised floor to form a positioning hole of the raised floor.

In this embodiment, the turning device 4 and the hole forming device 5 are disposed at the same processing position, so that the turning device 4 and the hole forming device 5 cooperate with the operation of the same set of transporting devices 1 a.

As shown in fig. 4A and fig. 5A, the hole forming device 5 includes a fourth base platform 51 adjacent to the third base platform 41, at least one fourth positioning element 52 disposed on the fourth base platform 51, a fourth supporting structure 53 disposed on the fourth base platform 51, at least one hole forming element 50 disposed on the fourth supporting structure 53 for performing hole forming on the target 9, at least one power set 55 for rotating the hole forming element 50, and at least one third servo motor 56 for lifting the hole forming element 50, and by providing an oil pressure or air pressure component (such as another power set 48 a), the third supporting structure 43 is displaced relative to the third base platform 41 to transport the target 9 to the fourth base platform 51, so that the hole forming element 50 forms a hole 900 on the target 9.

In this embodiment, the fourth base 51 and the third base 41 may be disposed in a coplanar manner, and the fourth base 51 defines a processing area A1 and a discharging area A2, so that the fourth positioning element 52 is disposed at the edge of the processing area A1 to limit the target 9 in the processing area A1, and the fourth supporting structure 53 covers the processing area A1, so that the hole-forming element 50 is movably disposed above the processing area A1 to perform hole-forming on the base 90 of the target 9, thereby achieving drilling of the countersunk hole required at the base 90 of the target 9, and extending the guide rail 45 into the processing area A1 of the fourth base 51. For example, after the third supporting structure 43 conveys the raised floor along the guiding rail 45 to the processing area A1, the fourth positioning element 52 limits the target 9, so as to facilitate the positioning of the target 9 on the fourth base 51.

Furthermore, the fourth positioning element 52 is disposed corresponding to the edge of the fourth base 51 to limit the displacement of the target 9, so that the target 9 is not deflected in the processing area A1. Specifically, according to the path direction of the feeding (from the third base 41 to the processing area A1) or the guide rail 45, the fourth positioning element 52 is disposed at the end point of the feeding path, such as the rear side and the right side of the processing area A1, so as to achieve the purpose of limiting the displacement of the feeding plate. For example, the fourth positioning member 52 is provided with a buffer 520 (such as a wheel, a bearing or the like) at the top end thereof to contact the target 9 in a forward sliding manner, so that the feeding plate and the target 9 thereon are not strongly clamped when entering the processing area A1, thereby reducing the friction force.

In addition, the fourth supporting structure 53 is a frame body, which covers the processing area A1 corresponding to the range of the processing area A1, and at least one power set 55 and a third servo motor 56 (as shown in fig. 5A) can be disposed thereon according to requirements, and the hole forming member 50 is in the form of a step drill (as shown in fig. 5B) and is disposed at the corner of the fourth supporting structure 53, so as to drill a hole at the foot 90 of the raised floor to form a countersunk hole.

In addition, a fixing structure 54a may be disposed at a position corresponding to the fourth positioning member 52 to contact and resist the target 9. For example, the fixing structure 54a, such as a physical pressing head or a vacuum suction head, is disposed at the lower side of the fourth supporting structure 53, and an oil pressure or air pressure component (not shown) is disposed to drive the fixing structure 54a to press the target 9. Preferably, a rake-shaped actuating member 57 with a telescopic structure is disposed at the processing area A1 in a direction corresponding to the discharging area A2, and an oil pressure or air pressure assembly (not shown) is used to push the side surface 9c of the target object 9 in the processing area A1, so that the target object 9 is forced to move to the discharging area A2 after the processing of the processing area A1 is completed.

In another embodiment, as shown in the hole forming device 5a of FIG. 5C, the third servo motor 56 can lift the hole forming member 50 via a lifting mechanism 58. For example, the power unit 55 is a spindle head driving motor, and as shown in fig. 5D, the lifting structure 58 includes a plurality of rails 58a disposed on the foot rest of the fourth supporting structure 53 and a lifting plate 58b disposed in a displaceable manner in cooperation with the rails 58a, so that a slidable slider 580 is disposed on the rails 58a, and the lifting plate 58b is provided with a slide 581 corresponding to the slider 580, so that the lifting plate 58b can be lifted and lowered along the rails 58 a. Further, the third servo motor 56 can be fixed on the top of the fourth supporting structure 53 by a speed reducer 560 to operate a ball screw 561 and a nut seat 562, wherein the speed reducer 560 is connected to the ball screw 561, and the nut seat 562 is connected to the ball screw 561 and fixed on the lifting plate 58b, so that when the third servo motor 56 drives the speed reducer 560 to rotate the ball screw 561, the ball screw 561 can drive the lifting plate 58b at the bottom of the nut seat 562 to make a linear reciprocating motion for a certain distance when rotating.

Preferably, the power assembly 55 and the hole forming member 50 are respectively disposed on the upper and lower sides of the lifting plate 58b, and a fixing plate 59a connected to the lower end of the power assembly 55 is fixedly disposed on the upper side of the lifting plate 58b, and a joint plate 59b connected to the upper end of the hole forming member 50 is fixedly disposed on the lower side of the lifting plate 58b, so that when the power assembly 55 drives the hole forming member 50 to rotate, the hole forming member 50 is driven to perform a lifting linear motion perpendicular to the surface of the processing area A1 by the cooperation of the lifting structure 58, so as to drill holes on the foot seats 90 of the raised floor to form countersunk holes.

It should be understood that the relative arrangement of the hole forming member 50 and its surroundings can be designed according to the requirement, and is not particularly limited as long as the hole forming member 50 can be lifted and rotated (by the cooperation of the power unit 55 and the third servo motor 56) at the same time.

When the processing equipment 1 is used in a production line, a single object 9 is conveyed into the edge milling device 3 by one of the pick-and-place assemblies 10 of the conveying device 1a for edge milling operation, so that the edge milling device 3 mills burrs on the flanges 91 on the four side surfaces 9c of the object 9.

In the present embodiment, the design of the cyclic displacement (the moving directions f1, f2, B1, B2 shown in fig. 3B) of the edge milling unit 3a of the edge milling device 3 is used to prevent the edge milling unit 3a from repeatedly milling the flange 91 on the same side surface 9c, so as to prevent the flange 91 on the side surface 9c of the target 9 from being excessively milled and damaged or the edge milling unit 3a from generating mechanical noise.

After the edge milling operation is completed, the object 9 is transported from the edge milling device 3 to the milling height device 2 by another pick-and-place assembly 10 of the transportation device 1a, so that the milling height device 2 performs the milling height operation (i.e. milling burr) on the four footstands 90 of the object 9.

Since the front and middle milling processes are performed on the bottom of the raised floor (the second surface 9b of the target 9), and the later drilling process is performed on the top surface of the raised floor (the first surface 9a of the target 9), the raised floor must be turned over before the drilling process. Therefore, the target 9 is transported from the milling height device 2 to the third positioning element 42 of the turnover device 4 by the other pick-and-place component 10 of the transportation device 1a, and the shaft structure 40 is rotated by the driving element 47, so that the third positioning element 42 is turned over along the shaft structure 40, the target 9 is placed on the third supporting structure 43 after being turned over 180 degrees, and then the third supporting structure 43 is slid to the processing area A1 of the hole forming device 5,5a by the guide rail 45. It should be understood that the object 9 may also be turned over manually.

Finally, the drilling operation (the hole opening 900 shown in fig. 1D) of the countersunk hole required at the foot 90 of the target object 9 is performed by the hole forming device 5,5a, and after the drilling operation is finished, the target object 8 (shown in fig. 1D) which is finished with the processing is pushed to the discharging area A2 by the action piece 57, so as to complete the processing flow of the whole raised floor.

To sum up, the hole forming device 5,5a of the present invention is mainly integrated with the power unit 55 and the hole forming member 50 in a straight line, so as to reduce the volume, accelerate the production process and improve the production efficiency, and reduce the labor intensity. Therefore, the main feature of the present invention is to use the power unit 55 to directly drive the hole-forming member 50 to rotate, which not only reduces the volume of the hole-forming member 50, but also controls the rotation of the power unit 55 by digital control to improve the precision and processing speed of the processing, which is the efficiency that the prior art can not achieve by using the common motor drive.

Furthermore, the utility model discloses a pore-forming device 5a borrows and can go up and down a plurality of power packs 55 by single third servo motor 56, as shown in fig. 5C, can not only go up and down simultaneously and rotate a plurality of pore-forming pieces 50 to improve the efficiency of processing, and can save this pore-forming device 5 a's cost.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Those skilled in the art can modify the above embodiments without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be defined by the appended claims.
