Description

Technical Field

[0001] This invention relates to the field of drawer panel processing technology, and more specifically to a multi-axis drilling center for drawer panel processing. Background Technology

[0002] In the production of panel furniture, the drawer panel is one of the core components, and its processing precision directly affects the assembly quality and service life of the furniture. The drilling process is a key step in the processing of the drawer panel. Multiple mounting holes of the same specifications and in precise positions need to be processed in different positions such as the front and sides of the drawer panel for subsequent assembly of hardware connectors to meet the opening and closing function requirements of the drawer.

[0003] Currently, the drilling equipment used in the processing of drawer panels is mostly traditional single-axis drilling machines or ordinary multi-axis drilling equipment. Existing drilling equipment is mostly equipped with a drilling structure in only one direction, which cannot simultaneously realize vertical drilling on the front and horizontal drilling on the side of the drawer panel. The drawer panel needs to be clamped and flipped multiple times for processing, which not only greatly increases the operation process and reduces the processing efficiency, but also easily causes positioning deviations due to multiple clamping, resulting in the hole position accuracy failing to meet the assembly requirements, and problems such as hole position offset and inconsistent hole diameter, which affect the stability of subsequent hardware assembly. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a multi-axis drilling center for drawer panel processing. This effectively solves the problem that existing drilling equipment is mostly equipped with a single-direction drilling structure, which cannot simultaneously perform vertical drilling on the front and horizontal drilling on the side of the drawer panel. This requires multiple clamping and flipping of the drawer panel, which not only significantly increases the number of operation steps and reduces processing efficiency, but also easily causes positioning deviations due to multiple clamping, resulting in hole position accuracy failing to meet assembly requirements and problems such as hole position offset and inconsistent hole diameter.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a multi-axis drilling center for processing drawer panels, comprising:

[0007] frame;

[0008] The top of the frame is equipped with a drilling mechanism, the inside of the frame is equipped with a conveying mechanism for conveying the drawer plates to be processed, and the bottom of the frame is equipped with a return material conveyor belt, and there are two return material conveyor belts that are symmetrically distributed on the left and right sides along the center plane of the frame.

[0009] The drilling mechanism includes a mounting frame fixedly installed on the top of the frame, and there are two mounting frames that are symmetrically distributed on the left and right sides along the center plane of the frame. The top of the mounting frame is equipped with a vertical drilling tool and the side wall of the mounting frame is equipped with a horizontal drilling tool. The output ends of the vertical drilling tool and the horizontal drilling tool on the same side are arranged perpendicularly.

[0010] The frame is equipped with a conveying mechanism on its outer side, which is used to transfer the processed drawer plate to the return material conveyor belt.

[0011] Furthermore, a material storage bin for storing the drawer panels to be processed is fixedly connected to the side of the frame away from the conveying mechanism.

[0012] Furthermore, the mounting bracket is equipped with a pressure plate via a cylinder disposed inside it, and the top of the pressure plate is provided with positioning holes, which are provided in multiples and arranged in an array along the center surface of the pressure plate.

[0013] Furthermore, the conveying mechanism includes a fixed frame that is fixedly installed in the frame, and there are two fixed frames that are symmetrically distributed on the left and right sides along the center plane of the frame. The fixed frame is equipped with a moving plate by a translation unit provided inside it. The moving plate is equipped with a mounting plate by an adjustment unit provided outside it. The top of the mounting plate is equipped with a clamping unit for limiting the drawer plate. The top of the mounting plate is also fixedly connected with a push plate.

[0014] Furthermore, the conveying mechanism includes a fixed plate fixedly connected to the outside of the frame, and the fixed plate has two plates that are symmetrically distributed on the left and right sides along the center plane of the frame. The fixed plate is equipped with a support plate via an electric slide rail on its outside. The distance between the two support plates is greater than the distance between the two return conveyor belts.

[0015] Furthermore, the support plate is slidably connected to a correction plate through a guide hole on its top, and the correction plate is connected to the inner wall of the guide hole through a return spring disposed on its outer side. A roller is fitted on the outer side of the correction plate, and multiple rollers are arranged in an array along the center surface of the correction plate. A ball is fitted on the side of the correction plate away from the return spring.

[0016] Furthermore, the fixing plate has a contact surface on the side near the correction plate that fits against the spherical surface of the rolling ball;

[0017] The contact surface is arranged vertically from top to bottom as a low-position region, a high-position region, and a low-position region.

[0018] The technical solution provided by this invention has the following advantages compared with the prior art:

[0019] This invention includes a drilling mechanism and a conveying mechanism. The drilling mechanism has a vertical drilling kit mounted on top and a horizontal drilling kit mounted on the outside, with their output ends arranged vertically to meet the requirements of vertical drilling on the front and horizontal drilling on the side of the drawer panel, respectively. During processing, only one clamping and positioning is required, and both drilling kits can start operating simultaneously, completely eliminating the cumbersome process of traditional equipment that requires multiple clamping and flipping to complete drilling in different directions. This significantly reduces the number of steps in the process. Simultaneously, a correction plate is slidably connected to the top of the support plate via guide holes. A ball bearing is embedded on the outside of the correction plate, and the fixed plate has a contact surface distributed in a "low-high-low" pattern, with the high and low areas of the contact surface forming a gradual slope transition. When the electric slide rail moves the support plate downwards, the ball bearing slides along the contact surface from the lower to the higher position. The slope exerts a horizontal squeezing force on the ball bearing, pushing the correction plate towards one side of the drawer panel and tightly fitting it against the side of the workpiece, achieving precise positioning and preventing workpiece displacement due to center of gravity shift or pushing deviation.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Example:

[0031] Please see Figures 1-6 This invention provides a technical solution: a multi-axis drilling center for processing drawer panels, comprising:

[0032] Rack 1;

[0033] The top of the frame 1 is equipped with a drilling mechanism 2, the inside of the frame 1 is equipped with a conveying mechanism 3 for conveying the drawer plate to be processed, and the bottom of the frame 1 is equipped with a return material conveyor belt 4, and there are two return material conveyor belts 4, which are symmetrically distributed on the left and right sides along the center plane of the frame 1.

[0034] The drilling mechanism 2 includes a mounting frame 21 fixedly installed on the top of the frame 1. There are two mounting frames 21, which are symmetrically distributed on the left and right sides along the center plane of the frame 1. The top of the mounting frame 21 is equipped with a vertical drilling kit 22, and the side wall of the mounting frame 21 is equipped with a horizontal drilling kit 23. The output ends of the vertical drilling kit 22 and the horizontal drilling kit 23 on the same side are arranged perpendicularly.

[0035] The outer side of the frame 1 is equipped with a conveying mechanism 5, which is used to transfer the processed drawer plate to the return material conveyor belt 4.

[0036] A material storage bin 6 for storing the drawer panels to be processed is fixedly connected to the side of the frame 1 away from the conveying mechanism 5.

[0037] Mounting bracket 21 is fitted with pressure plate 25 via cylinder 24 located inside it, and the top of pressure plate 25 is provided with positioning holes 251, which are provided in multiple and arranged in an array along the center surface of pressure plate 25.

[0038] The conveying mechanism 3 includes a fixed frame 31 fixedly installed in the frame 1, and the fixed frame 31 has two fixed frames 31 and is symmetrically distributed on the left and right sides along the center plane of the frame 1. The fixed frame 31 is equipped with a moving plate 33 by a translation unit 32 provided inside it. The moving plate 33 is equipped with a mounting plate 35 by an adjustment unit 34 provided on its outside. The top of the mounting plate 35 is equipped with a clamping unit 351 for limiting the drawer plate. The top of the mounting plate 35 is also fixedly connected to a push plate 352.

[0039] The conveying mechanism 5 includes a fixed plate 51 fixedly connected to the outside of the frame 1. The fixed plate 51 has two plates and is symmetrically distributed on the left and right sides along the center plane of the frame 1. The fixed plate 51 is equipped with a support plate 53 via an electric slide rail 52 on its outside. The distance between the two support plates 53 is greater than the distance between the two return conveyor belts 4.

[0040] The support plate 53 is slidably connected to the correction plate 55 through the guide hole 54 on its top, and the correction plate 55 is connected to the inner wall of the guide hole 54 through the return spring 56 provided on its outer side. The outer side of the correction plate 55 is fitted with a roller 57, and multiple rollers 57 are provided and arranged in an array along the center surface of the correction plate 55. A ball 58 is fitted on the side of the correction plate 55 away from the return spring 56.

[0041] The fixing plate 51 has an abutment surface 511 on the side near the correction plate 55 that fits against the spherical surface of the rolling ball 58;

[0042] The contact surface 511 is arranged vertically from top to bottom as a low-position area, a high-position area, and a low-position area.

[0043] The working principle and advantages of the multi-axis drilling center used for processing drawer panels:

[0044] In the large-scale processing of drawer panels, the drilling equipment currently used in the industry is mostly traditional single-axis drilling machines or ordinary multi-axis drilling equipment. These machines generally have structural limitations, being equipped with only a single-degree-of-freedom drilling actuator, enabling drilling operations only in one direction. They cannot simultaneously complete vertical drilling on the front and horizontal drilling on the sides of the drawer panel. Due to this limitation, the processing requires multiple clamping and positioning operations and workpiece flipping, which significantly increases process complexity, prolongs production cycle time, and reduces overall processing efficiency. Furthermore, multiple clamping operations can easily lead to cumulative positioning errors, affecting hole machining accuracy and failing to meet the accuracy and efficiency requirements of large-scale production.

[0045] The multi-directional drilling equipment for drawer plates proposed in this invention has an overall structure with the frame 1 as the installation reference. The side of the frame 1 away from the conveying mechanism 5 is equipped with a feeding bin 6 (workpiece storage unit) for centralized storage of drawer plates to be processed, realizing batch storage and orderly supply of workpieces, and providing a stable source of workpieces for subsequent automated feeding processes.

[0046] When the equipment starts and enters the drilling operation process, the conveying mechanism 3 starts simultaneously. This conveying mechanism 3 includes two fixed frames 31 symmetrically arranged along the central plane of the frame 1. A translation unit 32 is installed inside the fixed frame 31, driving a moving plate 33 to feed horizontally towards the material unloading bin 6. After the moving plate 33 moves to the preset material handling position, a lifting adjustment unit 34 installed on the outside of the moving plate 33 drives a mounting plate 35 to rise and fall vertically, so that the pneumatic clamping unit 351 at the top of the mounting plate 35 matches the height of the drawer plate to be processed. Subsequently, the clamping unit 351 drives the grippers to close, completing the clamping and limiting of the drawer plate, ensuring that the workpiece does not loosen or shift during the material handling process. Immediately afterwards, the translation unit 32 and the adjustment unit 34 work together to accurately transport the drawer plate to be processed in the material unloading bin 6 to the preset drilling position at the top of the fixed frame 31, completing the automated feeding and preliminary workpiece positioning process.

[0047] Once the drawer plate is precisely conveyed to the preset drilling position, the drilling mechanism 2 starts working. This drilling mechanism 2 also includes two mounting brackets 21 symmetrically arranged along the center plane of the frame 1. The clamping cylinders 24 embedded inside the mounting brackets 21 are activated, driving the pressure plate 25 to move vertically downwards, stably pressing the drawer plate against the processing reference surface (a flexible pad, such as a rubber pad, is provided on the side of the pressure plate 25 that contacts the drawer plate to prevent excessive pressure from the pressure plate 25, which could cause deformation or damage to the drawer plate), achieving secondary positioning and locking of the workpiece. The top of the pressure plate 25 has an array of positioning holes 251 corresponding one-to-one with the drilling holes. Simultaneously, the clamping unit 351 of the conveying mechanism 3 maintains a clamping state, forming a "double positioning and locking" structure, further ensuring the accuracy and stability of the hole processing.

[0048] After the drawer panel is pressed and fixed, the vertical drilling head 22 and the horizontal drilling head 23 of the drilling mechanism 2 start synchronously. The vertical drilling head at the top of the mounting bracket 21 is arranged vertically to process the vertical holes on the front of the drawer panel; the horizontal drilling head on the outside of the mounting bracket 21 is arranged horizontally to process the horizontal holes on the sides of the drawer panel. The output shafts of the two power heads are spatially vertically distributed, enabling multi-directional synchronous drilling in a single clamping state. This completely eliminates the cumbersome process of multiple clamping and workpiece flipping in traditional machining, significantly shortening the processing cycle and improving processing efficiency. Simultaneously, it effectively avoids positioning deviations caused by multiple clamping, ensuring that the positional accuracy, coaxiality, and other precision indicators of each hole meet design requirements.

[0049] After the drilling process is completed, the vertical and horizontal drilling heads retract synchronously along the feed direction, leaving the processing area to avoid collision with the workpiece. Subsequently, the clamping cylinder 24 drives the pressure plate 25 to reset vertically, while the clamping unit 351 simultaneously releases its clamping limit on the drawer plate. At the same time, the lifting unit drives the clamping unit 351 to move vertically downwards until the entire clamping unit 351 is below the bottom plane of the drawer plate. This design effectively prevents the clamping unit 351 from interfering with the processed drawer plate during its return stroke with the translation drive unit, ensuring the stability and reliability of the equipment operation. At this point, the processed drawer plate remains in the preset processing position at the top of the fixed frame 31, providing a workstation base for subsequent cyclic loading processes.

[0050] With the cooperation of the translation unit 32, the clamping unit 351 moves horizontally back to the material retrieval position of the feeding bin 6, restarts, and grabs another drawer plate to be processed from the feeding bin 6. After completing the material retrieval, the translation unit 32 starts again, and the clamping unit 351 carries the other drawer plate to be processed to the preset processing position. During this process, the push plate 352 fixed on the top of the moving plate 33 contacts the end face of the processed drawer plate on the fixed frame 31. As the moving plate 33 continues to feed, the push plate 352 smoothly pushes the processed drawer plate to one side of the conveying mechanism 5 until the drawer plate to be processed accurately reaches the preset processing position. At this time, the drilling mechanism 2 starts again to drill holes in the new drawer plate to be processed in multiple directions simultaneously. Through the above cycle, the continuous automated processing of drawer plates is realized, which greatly improves the efficiency of large-scale production.

[0051] It is worth noting that, in the initial state, the top planes of the two support plates 53 and the top plane of the fixing frame 31 have a preset height difference (the top of the fixing frame 31 is slightly higher than the top of the support plates 53). This height difference design ensures that the processed drawer plate can smoothly transition onto the support plate 53 under the action of the push plate 352, avoiding workpiece jamming or collision damage. When the drawer plate to be processed is fed from the material pick-up position of the feeding bin 6 to the processing position, the push plate 352 simultaneously pushes the processed drawer plate to the bearing area of ​​the support plate 53, realizing the orderly transfer of workpieces.

[0052] By employing the drilling mechanism 2 and the conveying mechanism 3, the following advantages are achieved:

[0053] Firstly, the mounting bracket 21 of the drilling mechanism 2 is equipped with a vertical drilling kit 22 on top and a horizontal drilling kit 23 on the outside. The output ends of both are arranged vertically, corresponding to the vertical drilling requirements on the front and horizontal drilling requirements on the side of the drawer panel, respectively. During processing, only one clamping and positioning is required, and the two drilling kits can start working simultaneously, completely eliminating the cumbersome process of traditional equipment that requires multiple clamping and flipping to complete drilling in different directions, thus reducing the number of operation steps in the process.

[0054] Secondly, after the drawer plate is transported to the processing position, it is initially clamped and limited by the clamping unit 351 of the conveying mechanism 3. Then, the cylinder 24 of the drilling mechanism 2 drives the pressure plate 25 downward to press the workpiece against the processing reference surface, forming a double positioning and locking structure of "clamping unit 351 + pressure plate 25". At the same time, the top of the pressure plate 25 is provided with an array of positioning holes 251 that correspond one-to-one with the drilling position, which further calibrates the drilling position and avoids workpiece displacement during processing, fundamentally reducing problems such as hole position deviation and inconsistent hole diameter.

[0055] Once the processed drawer panel has been fully moved onto the support plate 53, the two electric slide rails 52 drive assemblies start synchronously, driving the support plate 53 on the same side to move smoothly downwards in the vertical direction until the bottom of the drawer panel is in close contact with the conveying surface of the return material conveyor belt 4. At this time, the return material conveyor belt 4 starts, conveying the processed drawer panel at a uniform speed to the subsequent process station (such as grinding or assembly station), achieving seamless connection between processing and conveying, and further improving the automation level of the production process.

[0056] During the process of the drawer panel being pushed from the processing position (fixed frame 31) to the conveying position (support plate 53) by the push plate 352, problems such as uneven pushing force, workpiece center of gravity shift, slight deviation of the drawer panel's own size, and slight deviation of the pushing path will inevitably occur. The offset drawer panel will exceed the effective bearing capacity of the support plate 53, causing the offset drawer panel to come into contact with other components during the downward movement of the support plate 53 and the conveying of the return material conveyor belt 4, causing the drawer panel to fall off and not be able to enter the next process normally, thus affecting the processing efficiency.

[0057] To ensure the positional accuracy of the processed drawer panel during transport and to prevent workpiece displacement due to center of gravity shift or pushing deviation, a workpiece correction plate 55 is slidably fitted onto the top of the support plate 53 through a guide hole 54. The correction plate 55 is elastically connected to the inner wall of the guide hole 54 by a return spring 56 (a compression spring with stable elastic recovery performance), enabling the correction plate 55 to be telescopically adjustable. In the initial state, the support plate 53 is in an initial position slightly lower than the top of the fixed frame 31. At this time, the ball 58 fixed on the correction plate 55 is in the upper low position area of ​​the contact surface 511 on the side of the frame 1. The contact surface 511 does not exert a squeezing force on the ball 58, and the return spring 56 is in a free telescopic state without elastic deformation.

[0058] As the electric slide rail 52 drives the support plate 53 to move downwards, the ball 58 on the correction plate 55 moves gradually from the lower upper region to the higher region along the contact surface 511. The lower and higher regions of the contact surface 511 are transitioned by a gradual slope, with the upper slope having a long stroke and a gentle angle, and the lower slope having a short stroke and a steeper angle. As the ball 58 slides along the upper inclined surface, the inclined surface exerts a progressive horizontal squeezing force on the ball 58. This force exceeds the elastic threshold of the return spring 56, forcing the correction plate 55 to move smoothly along the guide hole 54 towards the drawer panel. The return spring 56 is gradually compressed until the ball 58 slides to the flat section of the high position area. At this point, the correction plate 55 is in close contact with the side of the drawer panel, completing the precise alignment. (During the movement of the support plate 53 from top to bottom along the abutment surface 511, a reserved gap is provided between the support plate 53 and the fixed plate 51. This reserved gap ensures that when the support plate 53 moves to the maximum width position of the fixed plate 51, the support plate 53 and the fixed plate 51 do not contact each other, avoiding motion interference between them.) This correction process involves smooth feeding and sufficient stroke time, ensuring correction accuracy.

[0059] When the electric slide rail 52 drives the support plate 53 close to the return conveyor belt 4, the ball 58 moves rapidly from the high-position plane section to the lower low-position area of ​​the contact surface 511. Constrained by the lower short-stroke, large-angle inclined structure, the ball 58 slides rapidly, and the squeezing force of the lower inclined surface on the ball 58 decreases rapidly. The return spring 56 rebounds instantaneously under the action of elastic restoring force, driving the correction plate 55 to quickly return along the guide hole 54, releasing the lateral restriction on the drawer plate. The return stroke time of the correction plate 55 is much shorter than the correction operation stroke time, which can avoid motion interference with the workpiece and the conveying mechanism 5, shorten the discharge cycle, and improve the overall conveying efficiency. At this time, the bottom of the drawer plate is in complete contact with the return conveyor belt 4, ensuring that the return conveyor belt 4 can smoothly and efficiently transport the processed drawer plate to the next station, ensuring the continuity and stability of the entire processing flow.

[0060] By using the contact surface 511 and the correction plate 55, the following advantages are available:

[0061] Firstly, the top of the support plate 53 is slidably connected to the correction plate 55 through the guide hole 54. A ball bearing 58 is embedded in the outer side of the correction plate 55. The fixing plate 51 has a contact surface 511 distributed in a "low-high-low" pattern, with the high and low areas of the contact surface 511 forming a gradual slope transition. When the electric slide rail 52 moves the support plate 53 downwards, the ball bearing 58 slides along the contact surface 511 from the upper low position to the upper position. The slope exerts a horizontal squeezing force on the ball bearing 58, pushing the correction plate 55 towards the drawer side and tightly fitting it against the side of the workpiece, thus completing precise alignment and preventing positional shift of the workpiece due to center of gravity offset or pushing deviation.

[0062] Secondly, the lower part of the contact surface 511 adopts a short-stroke, large-angle inclined structure. When the support plate 53 moves down to near the return conveyor belt 4, the rolling ball 58 quickly slides from the high part to the lower part. The squeezing force of the inclined surface on the rolling ball 58 decreases rapidly, and the return spring 56 rebounds instantaneously under the action of elastic restoring force, driving the correction plate 55 to quickly reset and release the lateral limit on the workpiece. The correction and reset stroke time is much shorter than the correction operation time, which avoids interference between the correction plate 55 and the workpiece and the conveying mechanism 5, and also greatly shortens the discharge cycle.
