Description

Technical Field

[0001] This application relates to a tool for processing burrs, particularly an automatic floor milling device. Background Art

[0002] Currently, raised floor devices are widely used in anti-static computer rooms or clean rooms. Among them, for existing raised floors made of aluminum alloy die-casting, generally, they need to go through five main processes: mold opening, aluminum melting, die-casting, forming, and trimming. Due to the forming process, there will be multiple burrs on the surface and bottom of the raised floor. During the installation process, on the one hand, these burrs will prevent the raised floors from fitting tightly together and also from fitting with the platform frame. On the other hand, it is not conducive to the installation by workers and there are certain safety concerns for the workers.

[0003] However, in the existing methods, it is necessary to manually remove the burrs on the four sides of the formed raised floor. This not only has low production efficiency, but also wastes a large amount of manpower and is time-consuming and laborious for each processing.

[0004] Therefore, how to overcome the above-mentioned deficiencies of the existing technology has actually become an urgent problem to be solved in the current industry. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the existing technology, this application provides an automatic floor milling device, including: a base having a working surface; a positioning structure disposed on the working surface for placing an object, wherein the object has opposite first and second surfaces, sides adjacent to the first and second surfaces, and a flange protruding from the sides, and there are four feet at the four corners of the second surface; a fixing part configured corresponding to the second positioning part to press the object onto the positioning structure; and a milling component disposed on the working surface in a displaceable manner and arranged on the side of the positioning structure to displace relative to the positioning structure to simultaneously complete the milling process of the four flanges of the object, and the milling component includes a milling tool, a support structure movably disposed on the base, and a carrying structure movably disposed on the support structure and carrying the milling tool to make the carrying structure and the milling tool approach or move away from the object, and a driving group is sleeved on a connecting part of the milling tool through a linkage part for linkage, wherein the milling tool includes a box body having an accommodation space, a main shaft passing through the accommodation space of the box body, a first bearing group and a second bearing group disposed in the box body and sleeved on the main shaft, and a tool structure disposed at one end of the main shaft.

[0006] In the aforementioned floor automatic milling edge device, the fixing part is disposed above and / or outside one of the diagonal corners of the positioning structure, and the fixing part generates a downward pressing or upward pulling movement through a power source. When the fixing part presses downward, it presses against the second surface of the target object, and when it pulls upward, it separates the target object.

[0007] In the aforementioned floor automatic milling edge device, a double-track structure is fixed on the base platform, and a sliding seat for mounting on the double-track structure is fixed at the bottom of the support structure, so that the sliding seat can slide on the double-track structure to drive the support structure to linearly displace, and the displacement direction of the support structure is perpendicular to the displacement direction of the bearing structure.

[0008] In the aforementioned floor automatic milling edge device, a ball nut is fixed on the support structure, and a ball screw is rotated by a motor to drive the ball nut to perform a linear motion, causing the support structure to linearly displace relative to the base platform along the edge of the positioning structure, so that the milling tool can linearly displace along the side surface of the target object to process the flange of the target object.

[0009] In the aforementioned floor automatic milling edge device, a limiting structure for guiding the displacement of the support structure is provided on the working surface of the base platform, and the limiting structure is a track structure, and at least one power group is provided on the base platform, and the power group includes a first motor for driving the support structure to displace and a second motor for driving the bearing structure to displace.

[0010] In the aforementioned floor automatic milling edge device, a track is configured on the support structure, and at least one slider matching the track is configured on the bearing structure, so that the slider moves on the track, causing the bearing structure to displace relative to the support structure.

[0011] In the aforementioned floor automatic milling edge device, a ball nut is fixed on the bearing structure, and a ball screw is rotated by a motor to drive the ball nut to perform a linear motion, so as to drive the bearing structure to linearly displace and displace the milling tool to a required position, and a driving group for actuating the milling tool is further configured on the bearing structure.

[0012] In the aforementioned floor automatic milling edge device, both the first bearing group and the second bearing group include two ball bearings and a bearing spacer ring disposed between the two ball bearings, and the ball bearings of the first bearing group are deep groove ball bearings, while the ball bearings of the second bearing group are angular contact ball bearings.

[0013] In the aforementioned floor automatic milling edge device, the tool structure includes a tool body, a tool joint seat and its tool shank, and the tool shank has a conical structure, and the tool body is joined to one end of the main shaft through the tool joint seat and its tool shank.

[0014] In the aforementioned floor automatic edge milling device, the milling cutter tool further includes a fixing base having a conical accommodating space, and the fixing base is formed at one end of the main shaft, and the tool shank is inserted through the conical accommodating space so that the tool structure is arranged at one end of the main shaft through the fixing base, thereby superimposing the tool body, the tool joint seat and the fixing base, and then combining them into one body.

[0015] In the aforementioned floor automatic edge milling device, the tool structure further includes a first bolt and a plurality of second bolts. The first bolt sequentially passes through the tool body, the tool joint seat, the fixing base, and the connecting member on the other end of the main shaft along the axial direction of the main shaft, and two nuts are used at both ends of the main shaft to lock the tool structure to the main shaft, and the connecting member is locked to the main shaft with another nut. The plurality of second bolts are arranged around the first bolt to lock the tool body and the tool joint seat to the fixing base.

[0016] In the aforementioned floor automatic edge milling device, a groove is formed on the surface of the tool joint seat, and a tenon is formed on the fixing base. After the tool joint seat is arranged on the fixing base, the tenon is clamped in the groove to fix the fixing base and the tool joint seat.

[0017] As can be seen from the above, the floor automatic edge milling device of the present application mainly uses the edge milling assembly to perform side burr milling treatment on objects such as raised floors, so as to speed up the production process and improve production efficiency, while reducing the manpower requirement.

[0122] The following illustrates the implementation modes of the present application through specific examples. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification.

[0123] It should be noted that the structures, ratios, sizes, etc. shown in the attached drawings of this specification are only used to cooperate with the content disclosed in the specification for the understanding and reading of those skilled in the art, and are not used to limit the implementation conditions of the present application. Therefore, they do not have technical essence. Any modification of the structure, change of the ratio relationship, or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present application. At the same time, the terms such as "upper", "lower", "front", "rear", "left", "right", and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the implementation scope of the present application. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope that the present application can implement.

[0124] Figure 1 This is a three-dimensional schematic diagram of the floor automatic milling edge device 3 of the present application applied to the production line. As Figure 1As shown, the production line further includes: a transport device 1, a floor automatic milling height device 2, a flipping device 4, and a hole-forming device 5.

[0125] In this embodiment, the transport direction of the transport device 1 according to the pre-treatment and post-treatment of the production line is defined as the left and right directions (such as the arrow direction Y), and the direction perpendicular to this transport direction is defined as the front and back directions (such as the arrow direction X), and the height direction along each device is defined as the up and down directions (such as the arrow direction Z). It should be understood that this orientation is used to illustrate the configuration of this embodiment and is not particularly limited.

[0126] Furthermore, the transport device 1 is used to transport (such as clamp) the target object 9 to the processing positions on the required production line. Therefore, the transport device 1 is arranged around the floor automatic milling height device 2, the floor automatic milling edge device 3, the flipping device 4, and the hole-forming device 5 to facilitate placing the target object 9 on the floor automatic milling height device 2, the floor automatic milling edge device 3, the flipping device 4, and / or the hole-forming device 5.

[0127] In addition, the target object 9 is an elevated floor, such as Figure 4A , Figure 4B and Figure 4C As shown, it has opposite first surface 9a (such as the floor surface) and second surface 9b (such as the bottom end side), and side surface 9c adjacent to the first and second surfaces 9a, 9b. For example, the target object 9 is generally in the shape of a rectangular body (such as a square plate), the bottom of the target object 9 (such as the side of the second surface 9b, which is the bottom of the elevated floor) is honeycomb-shaped, and pedestals 90 are formed at the four corners of the second surface 9b of the target object 9 to form openings at the four pedestals 90, and screws (not shown) are used to fix the four pedestals 90 to the support brackets for the elevated floor (not shown) respectively. Specifically, the end surface 9d of the pedestal 90 slightly protrudes (such as the height difference h shown in Figure 4C ) from the second surface 9b of the target object 9, and a flange 91 protruding from the side surface 9c is formed at the edge of the first surface 9a. Since the target object 9 in this embodiment is an elevated floor, the target object 9 will be referred to as an elevated floor hereinafter.

[0128] Figures 1A to 1C is a schematic diagram of the first embodiment of the floor automatic milling edge device 3 of the present application. In this embodiment, the described floor automatic milling edge device 3 operates in cooperation with the transport device 1 for processing such as Figure 1 and Figures 4A to 4CThe flange 91 on the side 9c of the target object 9 (raised floor) shown. The flange 91 enables the floor automatic milling device 3 to quickly process the four edges of the raised floor. For example, it removes the burrs on the four sides of the raised floor to process the dimensions of the four edges of the raised floor. Specifically, the processing values are input through the human-machine control interface in the form of a Programmable Logic Controller (PLC) to control the dimensions of the four edges of the raised floor to be processed.

[0129] As Figures 1A to 1C shown, the floor automatic milling device 3 includes a base 31, a positioning structure 32 provided on the base 31, and at least one milling component 3a provided on the base 31 and surrounding the positioning structure 32. The transportation device 1 places the target object 9 on the positioning structure 32, and the milling component 3a displaces relative to the positioning structure 32 to perform the milling process on the target object 9.

[0130] The base 31 is a machine tool workbench, which is generally in a rectangular shape, and its working surface S is also a rectangular plane.

[0131] In this embodiment, the base 31 can be configured with electromechanical components required for the production line, such as motors, wires, or other related units, without special restrictions.

[0132] The positioning structure 32 is configured at the middle of the working surface S of the base 31, as Figure 1A ’ shown, to position and carry the target object 9 as Figure 1 and Figures 4A to 4C shown.

[0133] In this embodiment, the positioning structure 32 is a multi-layer rectangular plate body, and it has a square placement platform 32a above it. The raised floor is placed on the placement platform 32a, and the milling components 3a are respectively arranged on the four sides of the placement platform 32a (a total of four milling components 3a are shown in this embodiment).

[0134] Furthermore, a plurality of fixing parts 320, 320’ can be configured on the outside of the placement platform 32a as required to limit the displacement of the target object 9 and avoid deviation. For example, a gantry-shaped support frame 39 is respectively provided on the front and rear sides of the base 31, as Figure 1A ” shown. The fixing part 320 is erected on the main frame 390 extending on the surface of the support frame 39. Therefore, after the target object 9 is placed on the placement platform 32a, the feet 90 of the target object 9 are clamped and fixed diagonally by these fixing parts 320 to prevent the target object 9 from deviating during the milling process.

[0135] In addition, the fixing part 320' can also be disposed above the placement platform 32a to restrict the displacement of the target object 9. For example, the support frame 39 is configured with a boom 391, as shown in Figure 1A ", which is pivotally connected to a bracket 392 to mount the fixing part 320' through the bracket 392. Therefore, after the target object 9 is placed on the placement platform 32a, by rotating the bracket 392, the fixing parts 320' are pressed down to fasten the second surface 9b of the target object 9 to prevent the target object 9 from being displaced during the milling edge process. Specifically, a rod 360' of a power source 36' (such as the hydraulic or pneumatic cylinder shown in Figure 2B ) is connected to the hole 320a of the bracket 392, so that when the rod 360' of the power source 36' performs a telescopic action to press down or pull up the fixing parts 320', the fixing parts 320' will press or separate the second surface 9b of the target object 9.

[0136] The milling edge assemblies 3a described above are multiple in number and are respectively disposed outside the respective sides (such as the front, rear, left, and right sides) of the positioning structure 32 (or the placement platform 32a).

[0137] In this embodiment, each of the milling edge assemblies 3a includes a milling tool 30, a support structure 33 provided on the base 31, and a carrier structure 34 provided on the support structure 33 to carry the milling tools 30. The milling tool 30 is configured with a milling cutter 300 at the top of its body 30a, and the carrier structure 34 is movably disposed on the support structure 33 to displace the milling tool 30 to a desired position. It should be understood that there are various types of milling cutters 300 and there is no special limitation.

[0138] Furthermore, the support structure 33 is a plate base body, which is disposed on the working surface S of the base 31 in a displaceable manner. For example, a position-limiting structure 37 for restricting the displacement direction of the support structure 33 and a power unit 38 for driving the support structure 33 and the bearing structure 34 to displace are provided on the working surface S of the base 31, and there are a total of four power units 38 respectively driving the support structure 33 and the bearing structure 34. Specifically, the position-limiting structure 37 is a double-rail structure, the double-rail structure is fixed on the base 31, and a sliding seat 330 for installing on the position-limiting structure 37 is fixed at the bottom of the support structure 33, so that the sliding seat 330 can slide on the position-limiting structure 37 to drive the support structure 33 to linearly displace. A ball nut (not shown) is fixed at the bottom of the support structure 33 and a ball screw 380 engaging with the ball nut (which is fixed on the working surface S of the base 31) is provided. The power unit 38 includes a first motor 38a, and there are a total of four power units 38, so as to respectively drive the ball screw 380 to rotate and drive the ball nut to perform linear motion through each first motor 38a at the same time, so that the support structure 33 linearly displaces along the edge of the positioning structure 32 relative to the base 31, so that the milling tool 30 can linearly displace along the side surface 9c of the object 9 to simultaneously machine the four flanges 91 of the object 9.

[0139] In addition, the bearing structure 34 is a frame base body, which is movably disposed on the support structure 33 to make the milling tool 30 approach or move away from the positioning structure 32, and the power unit 38 further includes a second motor 38b for driving the bearing structure 34 to displace. Among them, based on one side of the positioning structure 32, the displacement direction of the support structure 33 (such as Figure 1B the moving directions f2, b2 shown) and the displacement direction of the bearing structure 34 (such as Figure 1B the moving directions f1, b1 shown) are perpendicular to each other. For example, a track 35 is disposed on the upper side of the support structure 33 to make the slider 340 below the bearing structure 34 cooperate with the track 35, and the slider 340 moves on the track 35, so that the second motor 38b drives the bearing structure 34 to linearly displace relative to the support structure 33 along the track 35, so that the milling tool 30 can linearly displace to the required plane position or machining position to approach or move away from the positioning structure 32. Specifically, a ball nut (not shown) is fixed on the lower side of the bearing structure 34, and a ball screw (not shown) engaging with the ball nut is fixed on the support structure 33, so that the second motor 38b rotates the ball screw. Since the ball screw only rotates in place without moving, the ball screw actuates the ball nut to generate linear displacement, so that the ball nut linearly drives the bearing structure 34 to displace along the track 35, so that the milling tool 30 linearly displaces to the required machining position.

[0140] In addition, on the bearing structure 34, a driving group 36 and the milling tool 30 are respectively arranged on two brackets 34a, so as to actuate the milling tool 30 to rotate through the driving group 36, so that the milling cutter 300 removes the burrs on the flange 91 of the target object 9 at the target position (such as fitting the flange 91 on the side 9c of the target object 9). Specifically, the driving group 36 is, for example, a motor, which is connected to the milling tool 30 through a linkage 36a (such as a belt) via a connecting member 66 (such as a pulley), and when the driving group 36 is actuated, the milling tool 30 is linked to rotate through the linkage 36a.

[0141] Figures 2A to 2B FIG. is a schematic diagram of the second embodiment of the floor automatic milling edge device 3' of the present application. This embodiment is another mechanism design of the first embodiment, and the overall design is roughly the same, without adding or reducing the main components, so it will not be described in detail.

[0142] As Figure 3A and Figure 3B shown, taking the first embodiment as an example, when using the floor automatic milling edge device 3 on the production line, after the milling height operation is completed, the single target object 9 is transported from the floor automatic milling height device 2 to the placement platform 32a of the positioning structure 32 of the floor automatic milling edge device 3 through the transportation device 1, and the target object 9 is firmly abutted by the fixing parts 320, 320'. Among them, the first surface 9a of the target object 9 faces the placement platform 32a, and the second surface 9b faces upward.

[0143] Next, the bearing structure 34 is displaced close to (such as Figure 1B the moving direction f1 shown) the positioning structure 32 (or the placement platform 32a) through the second motor 38b, so as to displace the milling edge assembly 3a to the required position, and then the support structure 33 is linearly slid along the limiting structure 37 (such as Figure 1B the moving direction f2 shown) through the first motor 38a to move the milling tool 30, so that the driving group 36 is connected to the milling tool 30 through the linkage 36a (such as a belt) via the connecting member 66 (such as Figure 5 the pulley shown), so as to drive the milling cutter 300 of the milling tool 30 to mill the burrs on the flanges 91 of the four sides 9c of the target object 9, so that the milling edge assembly 3a performs the milling edge treatment on the target object 9 corresponding to each edge of the positioning structure 32 (or the placement platform 32a).

[0144] After that, the bearing structure 34 is displaced away from (such as Figure 1B the moving direction b1 shown) the positioning structure 32 (or the placement platform 32a) through the second motor 38b, so as to displace the milling tool 30 to the required position, and then the support structure 33 is linearly slid along the limiting structure 37 (such asFigure 1B The moving direction b2) as shown to move the edge milling assembly 3a back to the origin.

[0145] Figure 5 It is a sectional schematic view of a milling tool. As Figure 5 shown, the milling tool 30 includes a housing 60 having a receiving space S', a main shaft 61 passing through the receiving space S' of the housing 60, a first bearing set 62, a second bearing set 63 and a main shaft column 64 disposed in the housing 60 and sleeved on the main shaft 61.

[0146] Specifically, the housing 60 has corresponding first and second side surfaces 60a and 60b, and the main shaft 61 has corresponding milling cutter end 61a and linkage end 61b, and the main shaft 61 is a hollow shaft. After passing through the first side surface 60a of the housing 60 from the linkage end 61b into the receiving space S', it passes out of the second side surface 60b of the housing 60. Among them, a conical receiving space S1 in the shape of a conical hole is formed inside the milling cutter end 61a of the main shaft 61, thereby forming a fixing seat 610 for mounting a tool structure 65. The linkage end 61b is sleeved with the linkage member 36a to be coupled with the drive group 36 through the linkage member 36a. Thus, when the drive group 36 operates, the main shaft 61 and the tool structure 65 are linked to rotate through the linkage member 36a.

[0147] In one embodiment, the fixing seat 610 and the main shaft 61 are integrally formed, and a conical receiving space S1 in the shape of a conical hole is formed inside the fixing seat 610.

[0148] In one embodiment, the tool structure 65 includes a tool body 651, a tool joint seat 652 and a tool shank 653. The tool body 651 is disposed on the tool joint seat 652, and the tool joint seat 652 and the tool shank 653 are integrally formed. Thus, the tool body 651, the tool joint seat 652 and the fixing seat 610 are stacked and fixed together. Among them, the tool shank 653 has a conical structure, so that the outer shape of the tool shank 653 corresponds to the conical receiving space S1 in the fixing seat 610, and the tool shank 653 passes through the conical receiving space S1, and the tool joint seat 652 is joined to the fixing seat 610. In addition, a groove T is formed on the surface of the tool joint seat 652, and the fixing seat 610 is formed with a tenon 71. After the tool joint seat 652 is disposed on the fixing seat 610, the tenon 71 of the fixing seat 610 is used to clamp the groove T of the tool joint seat 652 to fix the fixing seat 610 and the tool joint seat 652.

[0149] In one embodiment, the linkage end 61b is provided with the connecting member 66, and the linkage member 36a is sleeved on the connecting member 66.

[0150] In one embodiment, the tool structure 65 further includes a first bolt 654 and a plurality of second bolts 655.
