Description

Technical Field

[0001] This utility model relates to the field of profile processing technology, specifically a four-sided drilling and milling machine for profile processing. Background Technology

[0002] Drilling and milling is a composite machining process that integrates the functions of "drilling" and "milling". It uses drilling and milling machine tools (such as vertical drilling and milling machines and CNC drilling and milling machines) to perform multiple processes such as hole processing, plane milling and contour forming on materials such as metal, plastic and wood. It is widely used in the fields of machinery manufacturing, mold making and automotive parts.

[0003] Some profiles, such as door and window profiles, require a large amount of drilling and milling operations. For example, drilling lock holes, handle holes, hardware notches, glue injection holes, corner bracket mounting holes, mullion mounting holes, drainage holes, frame mounting holes, mullion end face tenons, mullion connector holes, etc. Moreover, the structures that need to be drilled and milled are opened on different profile surfaces. Therefore, a four-sided drilling and milling device is needed to improve the drilling and milling efficiency of this type of profile.

[0004] In the prior art, Chinese Patent No. 201810139987.3 discloses a four-way drilling and milling processing device for glass window frame profiles, including a base, a lower drilling and milling mechanism on the base, the lower drilling and milling mechanism including a first transverse plate, a first lifting plate slidably connected to the first transverse plate, a rotary drilling and milling cutter on the first lifting plate, a movable frame above the base, a longitudinal groove on the movable frame, a mounting seat on the movable frame, an upper drilling and milling mechanism on the horizontal part of the mounting seat, the rotary drilling and milling cutter of the upper drilling and milling mechanism is set downwards, a left drilling and milling mechanism and a right drilling and milling mechanism are respectively set on the two vertical parts of the mounting seat, both the left drilling and milling mechanism and the right drilling and milling mechanism include a second lifting plate, a second transverse plate slidably connected to the second lifting plate, the second transverse plate is also set with a rotary drilling and milling cutter, the rotary drilling and milling cutters of the left drilling and milling mechanism and the right drilling and milling mechanism are set facing each other, and a profile positioning mechanism is provided on the movable frame.

[0005] According to its disclosed content, the four-way drilling and milling device for glass window frame profiles uses four drilling and milling motors with different orientations to perform four-sided drilling and milling operations on the profiles. Each of the four drilling and milling motors is equipped with an independent drive assembly to achieve the four-sided drilling and milling function; that is, four sets of drive assemblies are provided for the four drilling and milling motors to achieve the corresponding vertical and horizontal movement. Although the four-way drilling and milling device disclosed in this patent can achieve four-sided drilling and milling, the excessive use of drive assemblies results in a large investment in the device and a relatively complex structure, leading to high maintenance costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0022] like Figures 1 to 6 As shown, a four-sided drilling and milling machine for profile processing includes a bed frame 1. A base plate 201 is provided on the top of the bed frame 1. A vertical plate 202 is fixed on the top of the base plate 201. A vertical sliding plate 203 that can slide up and down is provided on the front side of the vertical plate 202, and a first driving device for driving the vertical sliding plate 203 to move. A horizontal sliding plate 204 that can slide left and right is provided on the front side of the vertical sliding plate 203, and a second driving device for driving the horizontal sliding plate 204 to move.

[0023] Furthermore, the base plate 201 is slidably connected to the bed frame 1 in the front-to-back direction, and the bed frame 1 is provided with a drive device 3 for driving the base plate 201 to move.

[0024] As one specific implementation method, such as Figures 2 to 4 As shown, the front side of the upright plate 202 is provided with at least two vertically extending front vertical extension plate seats 2021, and the rear side of the vertical sliding plate seat 203 is provided with a vertically extending rear vertical extension plate seat 2031 that corresponds one-to-one with the front vertical extension plate seats 2021. The front vertical extension plate seats 2021 and the corresponding rear vertical extension plate seats 2031 are connected by a linear guide rail and a slider in a sliding engagement.

[0025] Specifically, such as Figure 4 As shown, the driving device is a lead screw motor 231 fixed to the bottom of the base plate 201. The lead screw corresponding to the lead screw motor 231 passes through the base plate 201 and extends above the base plate 201 (i.e., the axis of the lead screw extends vertically). The lead screw corresponding to the lead screw motor 231 is located between the upright plate 202 and the vertical sliding plate seat 203. The suspended end of the lead screw is connected to the front surface of the upright plate 202 through a bearing seat. The rear surface of the vertical sliding plate seat 203 is provided with a lead screw slider that cooperates with the lead screw corresponding to the lead screw motor 231.

[0026] As one specific implementation method, such as Figures 2 to 4As shown, the front side of the vertical sliding plate seat 203 is provided with at least two horizontally extending front horizontal extension plate seats 2032, and the rear side of the horizontal sliding plate seat 204 is provided with a horizontally extending rear horizontal extension plate seat 2041 that corresponds one-to-one with the front horizontal extension plate seats 2032. The front horizontal extension plate seats 2032 and the corresponding rear horizontal extension plate seats 2041 are connected by linear guide rails and sliders in a sliding engagement.

[0027] Specifically, such as Figure 2 As shown, the second driving device is a lead screw motor 232 fixed to the front surface of the vertical sliding plate seat 203. The lead screw corresponding to the lead screw motor 232 extends between the vertical sliding plate seat 203 and the horizontal sliding plate seat 204. The axis of the lead screw extends horizontally, and the suspended end of the lead screw is connected to the front surface of the vertical sliding plate seat 203 through a bearing seat. The rear surface of the horizontal sliding plate seat 204 is provided with a lead screw slider that cooperates with the lead screw corresponding to the lead screw motor 232.

[0028] It should be noted that all the above-mentioned lead screw motors and lead screw sliders are conventional technologies, and the specific settings will not be elaborated on here.

[0029] Specifically in this embodiment, such as Figure 5 and Figure 6 As shown, the base plate 201 and the bed frame 1 are connected by a linear guide rail and a sliding block. A motor base 208 is located at the bottom of the base plate 201. The driving device is a drive motor 235 fixed to the motor base 208. The drive motor 235 is preferably a servo motor. A gear 241 is coaxially fixed on the power output shaft of the drive motor 235. A rack 242 extending along the front-back direction on the bed frame 1, meshing with the gear 241, is also provided. The drive motor 235 drives the gear 241 to rotate, and under the reaction force of the rack 242, the drive motor 235 moves the four-sided drilling and milling mechanism 2 along the front-back direction of the bed frame 1. The gear and rack driving method is a conventional technology, and its specific principle will not be elaborated further.

[0030] like Figures 2 to 4 , Figure 8As shown, the front side of the transverse sliding plate seat 204 is respectively provided with an upper drilling and milling motor 211, a lower drilling and milling motor 212, a first side drilling and milling motor 213, and a second side drilling and milling motor 214. The drill bit of the upper drilling and milling motor 211 is arranged downwards. The first side drilling and milling motor 213 and the second side drilling and milling motor 214 are located below the left and right sides of the upper drilling and milling motor 211, respectively. The two drill bits corresponding to the first side drilling and milling motor 213 and the second side drilling and milling motor 214 are arranged inwards (with the opposite side of the first side drilling and milling motor 213 and the second side drilling and milling motor 214 as the inner side). The lower drilling and milling motor 212 is located below the upper drilling and milling motor 211, and the corresponding drill bit is arranged upwards.

[0031] Specifically in this embodiment, such as Figure 8 As shown, the transverse sliding plate base 204 comprises, from top to bottom, an upper plate portion 204a, a middle plate portion 204b, a connecting portion 204c, and a lower plate portion 204d. Two middle plate portions 204b are designed and located on either side below the upper plate portion 204a. The lower plate portion 204d is connected to either middle plate portion 204b via the connecting portion 204c. The upper drilling and milling motor 211 is bolted to the upper plate portion 204a. Side drilling and milling motors 213 and 214 are bolted to their respective middle plate portions 204b. The lower drilling and milling motor 212 is bolted to the lower plate portion 204d.

[0032] It also includes at least two sets of clamping wheel sets located on the front and rear sides of all drilling and milling motors (upper drilling and milling motor 211, lower drilling and milling motor 212, side drilling and milling motor 213 and side drilling and milling motor 214). Since all drilling and milling motors are fixed on the transverse sliding plate seat 204, the clamping wheel sets are located on the front and rear sides of the sliding plate seat 204.

[0033] In this embodiment, the clamping wheel assembly includes a fixed horizontal limiting wheel 221 and a movable horizontal limiting wheel 222, both extending laterally in the axial direction. The fixed horizontal limiting wheel 221 is fixed to the top of the base plate 201 via a wheel axle seat. The movable horizontal limiting wheel 222 is vertically slidably disposed above the base plate 201, preferably directly above the fixed horizontal limiting wheel 221. The clamping wheel assembly also includes a fixed vertical limiting wheel 223 and a movable vertical limiting wheel 224, both extending vertically in the axial direction. The fixed vertical limiting wheel 223 and the movable vertical limiting wheel 224 are located on the left and right sides of the corresponding fixed horizontal limiting wheel 221, respectively. The fixed vertical limiting wheel 223 is fixed to the top of the base plate 201 via a wheel axle seat. The movable vertical limiting wheel 224 is horizontally slidably disposed above the base plate 201, preferably directly to the left or right of the fixed vertical limiting wheel 223. The clamping wheel assembly also includes a fourth drive device for driving the movable horizontal limit wheel 222 to move and a fifth drive device for driving the movable vertical limit wheel 224 to move.

[0034] Specifically, in this embodiment, the top of the base plate 201 is provided with an upwardly extending stand 205. One side of the stand 205 is connected to a rotating wheel seat 206 via a linear guide rail and a slider. The movable horizontal limiting wheel 222 is rotatably mounted on the rotating wheel seat 206 via a wheel axle seat. Since the axis of the fixed vertical limiting wheel 223 is arranged vertically, the fixed vertical limiting wheel 223 can be fixed to one side of the stand 205 according to the adaptive design.

[0035] Specifically, such as Figures 2 to 4 As shown, the fourth driving device is a cylinder 233 fixed to the bottom of the base plate 201. The driving arm of the cylinder 233 passes through the base plate 201 and extends to the top of the base plate 201. The driving arm of the cylinder 233 is fixedly connected to the wheel seat 206.

[0036] Specifically, in this embodiment, the top of the base plate 201 is connected to the second rotating wheel 207 via a linear guide rail and a slider, and the movable vertical limiting wheel 224 is rotatably mounted on the top of the second rotating wheel 207 via a wheel axle seat.

[0037] Specifically, such as Figure 2 As shown, the fifth driving device is a cylinder 234 fixed to the top of the base plate 201, and the driving arm of the cylinder 234 is fixedly connected to the wheel base 207.

[0038] It is important to note that, to ensure the profile can pass smoothly through the vertical plate 202 for normal processing and to prevent the vertical plate 202 from interfering with the outward movement of the processed profile from the four-sided drilling and milling mechanism 2, a profile outlet 2012 is provided on the vertical plate 202 for the processed profile to pass through. The design of the profile outlet also applies to the vertical sliding plate 203. That is, based on the actual shape of the vertical sliding plate 203 and its vertical movement, if the vertical sliding plate 203 would interfere with the movement of the profile, a profile outlet is also provided in the vertical sliding plate 203 through adaptive design. All the above profile outlet designs are adaptive adjustments; the specific setting method can be designed according to the structural adaptability of the actual sheet material, and the specific setting method will not be elaborated further.

[0039] In this embodiment, the transverse sliding plate base 204 comprises, from top to bottom, an upper plate portion 204a, a middle plate portion 204b, a connecting portion 204c, and a lower plate portion 204d to accommodate the installation of multiple drilling and milling motors. Therefore, in practical applications, the vertical height of the transverse sliding plate base 204 is higher than that of the vertical plate 202. To avoid interference between the transverse sliding plate base 204 and the base plate base 201 during movement, a laterally extending clearance opening 2011 is adaptively designed on the base plate base 201 for the lower plate portion 204d to pass through, ensuring the normal movement of the transverse sliding plate base 204. The design of the clearance opening 2011 is also an adaptive adjustment; the specific setting method will not be described in detail.

[0040] Working principle: The profile to be drilled and milled is fed into the machining range of the four-sided drilling and milling mechanism 2 through the profile feeder and clamping wheel set. By controlling cylinders 233 and 234, the movable horizontal limit wheel 222 and the movable vertical limit wheel 224 are moved respectively, so that the movable horizontal limit wheel 222 moves closer to the fixed horizontal limit wheel 221 and the movable vertical limit wheel 224 moves closer to the fixed vertical limit wheel 223, and finally the profile is clamped on each limit wheel (movable horizontal limit wheel 222, fixed vertical limit wheel 223, fixed vertical limit wheel 224, fixed vertical limit wheel 223). Between the limiting wheel 221, the movable vertical limiting wheel 224 and the fixed vertical limiting wheel 223, the four-sided drilling and milling mechanism 2 is driven by the drive motor 235 and moves along the front and rear direction of the bed frame 1, thereby driving the clamping wheel group (movable horizontal limiting wheel 222, fixed horizontal limiting wheel 221, movable vertical limiting wheel 224 and fixed vertical limiting wheel 223) to move with the four-sided drilling and milling mechanism 2 and keep following to the position where the profile needs to be processed; the clamping wheel group can always follow the drilling and milling motor to move, which can stably and effectively control the profiles of all sizes.

[0041] Subsequently, by controlling the lead screw motor 231, the vertical sliding plate seat 203 is moved vertically. Simultaneously, the vertical sliding plate seat 203 moves vertically, causing the horizontal sliding plate seat 204 and the various drilling and milling motors (upper drilling and milling motor 211, lower drilling and milling motor 212, side drilling and milling motor 213, and side drilling and milling motor 214) located on the horizontal sliding plate seat 204 to move vertically. The upper drilling and milling motor 211 moves downwards to perform drilling and milling operations on the upper surface of the profile, while the lower drilling and milling motor 212 moves upwards to perform drilling and milling operations on the bottom surface of the profile. By controlling the lead screw motor 232, the horizontal sliding plate seat 204 and the various drilling and milling motors located on the horizontal sliding plate seat 204 are moved left and right. The side drilling and milling motors 213 and 214 perform drilling and milling operations on the left and right sides of the profile, respectively. In this way, only two lead screw motors can drive four drilling and milling motors to move in four directions: up, down, left, and right. The drive motor 235 cooperates to drive each drilling and milling motor to move in the forward and backward directions. Within the movable range of the drilling and milling mechanism 2, it can continuously move to complete the four-sided drilling and milling processing of different positions of the profile.

[0042] After drilling and milling the profile on all four sides within the movable processing range of the drilling and milling mechanism 2, the profile can continue to be fed into the movable processing range of the four-sided drilling and milling mechanism 2 by the profile feeder to perform the above-mentioned four-sided drilling and milling processing.

[0043] It should be noted that profile feeders are a conventional technology. The profile feeders available on the market are typically fully automatic servo profile feeders. The appropriate profile feeder can be selected based on the specific processing needs of the drilling and milling products; specific models are not listed here. Naturally, the specific structure and operating principles will not be elaborated upon.

[0044] Furthermore, this embodiment also includes a PLC controller for controlling various motors (upper drilling and milling motor 211, lower drilling and milling motor 212, side drilling and milling motor 213, side drilling and milling motor 214, lead screw motor 231, lead screw motor 232, and drive motor 235) and cylinders (cylinder 233 and cylinder 234) to achieve automatic control of profile drilling and milling. Based on the shape of different profiles and drilling and milling requirements, automatic control programs for different profiles are obtained and saved after debugging. When processing the same type of profile subsequently, the corresponding automatic control program can be called from the PLC controller to achieve automated drilling and milling of the profile. PLC control technology is a conventional existing technology, and its specific principles will not be elaborated upon.

[0045] like Figures 8 to 12 As shown, Figures 8 to 12 The rectangular area directly opposite each of the drilling and milling motors shown (upper drilling and milling motor 211, lower drilling and milling motor 212, side drilling and milling motor 1 213 and side drilling and milling motor 2 214) is the profile drilling and milling processing area. When any one of the drilling and milling motors is working in the profile drilling and milling processing area, all other drilling and milling motors are kept away from the drilling and milling processing area to avoid interference between the drilling and milling motors and ensure production and processing safety.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
