Description

Technical Field

[0001] This utility model relates to the field of mold machining equipment technology, and in particular to a drilling and positioning device for machining the right cover mold of an automobile. Background Technology

[0002] In the manufacturing process of automotive parts, the processing quality of the right-side cover mold directly determines the assembly accuracy and appearance quality of the final product. Drilling, as an indispensable process in mold processing, has extremely high requirements for positional accuracy and processing stability. Due to the irregular geometric shape and large self-weight of the right-side cover mold, it must be firmly fixed on the processing platform during drilling operations to prevent the cutting force generated at the moment of contact of the drill bit from causing the mold to shift.

[0003] To ensure the permeability of the drilled holes and facilitate the smooth removal of waste chips generated during processing, the mold needs to be raised to a certain height from the worktable so that it is suspended in the air for processing. At the same time, the mold also needs to be clamped and positioned horizontally. However, existing mold processing equipment often uses a separate drive structure to achieve this process. That is, it requires an independent lifting mechanism, such as a hydraulic jack, to lift the mold vertically, and an additional independent clamping mechanism, such as a manual screw and a pneumatic clamp, to fix it horizontally.

[0004] This separate structural design has significant drawbacks. First, it makes the internal structure of the equipment extremely bulky, with numerous power sources and transmission lines, increasing the manufacturing cost and maintenance difficulty. Second, in actual operation, workers need to control the lifting and clamping systems separately, which is not only cumbersome to operate, but also makes it difficult to ensure that the mold can be clamped synchronously and accurately when it is raised to the predetermined height. The coordination between processes is poor, reducing the overall processing efficiency.

[0005] Therefore, this utility model proposes a drilling and positioning device for processing the right cover mold of an automobile to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology, the automobile right cover mold processing equipment adopts a separate drive structure to control the lifting and horizontal clamping of the mold separately, which results in a bulky and complex internal structure, multiple power sources leading to high manufacturing costs, poor coordination between lifting and clamping actions during operation, and difficulty in automatically collecting processing waste. The present invention aims to provide an automobile right cover mold processing drilling and positioning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a drilling and positioning device for processing a right-side cover mold of an automobile, comprising: an operating table, a linear module fixedly connected to the top rear side of the operating table, a slide fixedly connected to the movable end of the linear module, an outer frame fixedly connected to the top of the slide, a cylinder fixedly connected to the inside of the outer frame, a slide fixedly connected to the output end of the cylinder, and a drilling machine fixedly connected to the top front side of the slide.

[0008] The operating platform is fixedly connected to the mounting plate inside, the bottom of the mounting plate is fixedly connected to the motor, the output end of the motor is fixedly connected to the rotating column, the top of the rotating column is provided with a threaded structure and threadedly connected to the lifting plate, the bottom of the lifting plate is fixedly connected to the limiting column, and the limiting column is slidably connected to the inside of the mounting plate.

[0009] Furthermore, the rotating block is fixedly connected to the outer wall of the rotating column, and the connecting rod is rotatably connected to both the front and rear sides of the rotating block. The end of the connecting rod away from the rotating block is rotatably connected to the movable platform. The slider is fixedly connected to both the front and rear sides of the top of the movable platform. The sliding column is slidably connected to the inside of the slider, and the top of the sliding column is fixedly connected to the top of the inside of the operating platform. The corner positioning wheel is fixedly connected to the top of the movable platform, and the waste bin is fixedly connected to the inside of the operating platform. The waste bin is located below the lifting plate.

[0010] Preferably, the top of the lifting plate has a waste hole that penetrates the plate body, and the position of the waste hole corresponds vertically to the top opening of the waste bin, so that the waste generated by drilling can directly enter the interior of the waste bin for collection through the waste hole.

[0011] Preferably, the number of movable platforms is set to two, the number of connecting rods is set to four, the rotating block is rotatably connected to the two movable platforms respectively through the connecting rods, and the two movable platforms are symmetrically distributed about the axis of the rotating column to achieve bidirectional synchronous clamping of the mold.

[0012] Preferably, the number of mounting plates is set to two, and the two mounting plates are respectively fixedly connected to the inner sides of the operating table. The motor is located between the two mounting plates, and the limiting column is slidably connected to the inside of the two mounting plates, thereby providing stable lifting guidance for the lifting plate.

[0013] Preferably, the side wall of the outer frame is provided with a vertical sliding groove, the slide is slidably connected to the inside of the vertical sliding groove, and the cylinder drives the slide and the drilling machine to reciprocate in the vertical direction along the vertical sliding groove through its piston rod, so as to ensure the verticality and stability of the drilling machine during the lifting process.

[0014] Preferably, the outer wall of the corner positioning wheel is provided with a rubber anti-slip layer. The corner positioning wheel is used to fit and conform to the corner and edge of the right cover mold of the car, providing flexible clamping while using friction to prevent the mold from shifting.

[0015] Preferably, the linear module specifically includes a guide rail base and a movable base slidably connected to the top of the guide rail base. The guide rail base is fixedly connected to the top of the operating table by bolts, and the slide is fixedly connected to the top of the movable base, for realizing the horizontal position adjustment of the drilling machine.

[0016] Preferably, the number of sliding columns is set to four, and the four sliding columns are distributed in a rectangle around the rotating column. The bottom end of the sliding column is suspended and fixedly connected to the bottom of the inner end of the operating table, providing stable guiding support for the horizontal movement of the movable table.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the lifting and fixing of molds and horizontal clamping often require multiple power sources to control them separately, resulting in complex equipment structure and poor coordination. It achieves the effect of automatic lifting and four-sided positioning and clamping of molds with only a single power source, which greatly simplifies the mechanical structure and reduces the manufacturing cost and energy consumption of the equipment.

[0018] 2. This utility model solves the problem that straight clamps in the prior art are difficult to adapt to the irregular corners and edges of the right cover mold of automobiles, and that rigid contact will damage the mold surface, by setting corner positioning wheels on the top of the movable table and wrapping the wheel body with a rubber anti-slip layer. It achieves the effect that the positioning wheels can closely fit the irregular contour of the mold for flexible fixation, and effectively protect the mold surface while increasing the clamping friction to prevent displacement, thereby improving the processing accuracy and yield.

[0019] 3. This utility model solves the problem in the prior art that metal shavings generated during drilling accumulate on the workbench by opening a through waste hole at the top of the lifting plate and setting a waste bin inside the operating table directly below the lifting plate. This not only makes the waste difficult to clean but may also affect the flatness of the subsequent mold placement. The invention achieves the effect of automatically collecting waste materials by having them fall directly into the waste bin through the lifting plate under gravity, keeping the processing area clean and reducing the burden of manual cleaning.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides a drilling and positioning device for processing automobile right cover molds, which aims to solve the problems in the existing automobile right cover mold processing equipment that lack a dedicated positioning mechanism for irregular corner parts, and that poor linkage between mold lifting and clamping leads to cumbersome operation and difficulty in collecting waste.

[0024] like Figure 1 and Figure 2As shown, the drilling and positioning device for processing the right cover mold of an automobile includes an operating table 1, a linear module 2 fixedly connected to the top rear side of the operating table 1, a slide 3 fixedly connected to the movable end of the linear module 2, an outer frame 4 fixedly connected to the top of the slide 3, a cylinder 5 fixedly connected to the inside of the outer frame 4, a slide 6 fixedly connected to the output end of the cylinder 5, and a drilling machine 7 fixedly connected to the top front side of the slide 6. The operating table 1 serves as the basic supporting component of the entire device and is used to place the right cover mold of the automobile to be processed. The linear module 2 specifically includes a guide rail seat and a movable seat slidably connected to the top of the guide rail seat. The guide rail seat is fixedly connected to the top of the operating table 1 by bolts, and the slide 3 is fixedly connected to the top of the movable seat. The linear module 2 is used to adjust the position of the drilling machine 7 in the horizontal direction to adapt to the needs of different processing coordinates. The side wall of the outer frame 4 is provided with a vertical slide groove, and the slide 6 is slidably connected to the inside of the vertical slide groove. The cylinder 5 drives the slide 6 and the drilling machine 7 to reciprocate in the vertical direction along the vertical slide groove through the piston rod, thereby adjusting the height of the drill bit and completing the feed action.

[0025] like Figure 2 and Figure 3 As shown, in order to construct the core power transmission and lifting execution system inside the device, two mounting plates 8 are fixedly connected inside the operating platform 1 and are respectively fixedly connected to the two side walls inside the operating platform 1. The motor 9 is installed in the space between the two mounting plates 8. The output end of the motor 9 is fixedly connected to the bottom end of the rotating column 10 to provide rotational torque. The rotating column 10 extends vertically upward as a transmission component. The top of the rotating column 10 is machined with an external thread structure. The lifting plate 11 is horizontally set above the rotating column 10 and has an internal thread hole at the center of its bottom. The threaded end of the rotating column 10 is screwed into the internal threaded hole of the lifting plate 11 to form a threaded transmission engagement. At the same time, multiple vertically downward limiting columns 12 are fixedly connected to the bottom edge of the lifting plate 11. The limiting columns 12 slide through the pre-set guide holes on the mounting plate 8. The sliding engagement between the limiting columns 12 and the mounting plate 8 can effectively restrict the lifting plate 11 from rotating with the rotating column 10, thereby converting the rotational motion of the rotating column 10 into the linear lifting motion of the lifting plate 11 in the vertical direction, providing the necessary space conditions for the subsequent lifting of the mold and the falling of the waste.

[0026] To achieve both vertical lifting and horizontal clamping, a rotating block 16 is fixedly mounted on the middle of the outer wall of the rotating column 10. The rotating block 16 rotates synchronously with the rotating column 10 and serves as the active component for horizontal drive. Connecting rods 17 are rotatably connected to the front and rear sides of the rotating block 16 via pins. A total of four connecting rods 17 are arranged in groups and connected to both sides of the rotating block 16. The end of each connecting rod 17 away from the rotating block 16 extends outward and is rotatably connected to two movable platforms 13 located on both sides of the rotating column 10. The movable platforms 13, serving as carriers for horizontal movement, are fixed on both the front and rear sides of their tops. A slider 14 is installed, and a vertical through hole is opened inside the slider 14. A sliding column 15 is slidably inserted into the through hole. The number of sliding columns 15 is set to four and they are arranged in a rectangular shape. The top end of the sliding column 15 is fixedly connected to the top wall inside the operating table 1 and the bottom end is fixedly connected to the bottom end inside the operating table 1 to form a stable guide rail. When the rotating block 16 rotates with the rotating column 10, it can drive the two movable tables 13 to move closer and further away from each other on the horizontal plane along the arrangement direction of the sliding columns 15 through the pulling and pushing action of the connecting rod 17 and the linear guiding constraint of the slider 14 on the sliding column 15.

[0027] To further improve the positioning stability of the irregular edges and corners of the right cover mold of the car, a corner positioning wheel 18 is fixedly connected to the top of the movable table 13. The corner positioning wheel 18 specifically includes a wheel axle and a rubber roller rotatably connected to the outer wall of the wheel axle. The bottom end of the wheel axle is fixedly connected to the top of the movable table 13. The outer wall of the rubber roller is provided with a rubber anti-slip layer to increase the friction with the mold surface and prevent rigid contact damage to the mold surface. The two movable tables 13 are symmetrically distributed about the axis of the rotating column 10 to ensure the force balance during clamping. In response to the problem of metal waste disposal generated during drilling, a waste hole penetrating the plate body is opened at the top of the lifting plate 11. The position of the waste hole corresponds vertically to the position of the top opening of the waste box 19. The waste box 19 is fixedly connected to the inside of the operating table 1 and located directly below the lifting plate 11. The waste generated during drilling can fall directly into the waste box 19 under the action of gravity through the waste hole for centralized collection.

[0028] Working Principle: Before using the equipment, the position of the operating table 1 must be determined and fixed securely to ensure processing accuracy. The operating table 1 serves as the basic load-bearing component of the entire device, used to stably place the right-side car cover mold to be processed. A linear module 2 is fixedly connected to the top rear side of the operating table 1. After the linear module 2 is powered on, it drives the moving seat to slide horizontally on the guide rail. The moving seat drives the slide table 3 fixedly connected to the top to move synchronously. The slide table 3 then drives the outer frame 4 fixedly connected to the top to move horizontally. Thus, by changing the horizontal position of the outer frame 4, the drilling machine located in front of the outer frame 4 can be adjusted. The horizontal machining coordinates of 7 meet the drilling requirements of different hole positions in the right cover mold of the car. After the horizontal position is adjusted, the cylinder 5 fixedly connected inside the outer frame 4 is started. The piston rod of the cylinder 5 extends and retracts, causing the slide 6 fixedly connected at the output end to slide in the vertical slide groove opened on the side wall of the outer frame 4, thereby driving the drilling machine 7 fixedly connected to the top front side of the slide 6 to move vertically up and down. By precisely controlling the stroke of the cylinder 5, the distance between the drill bit and the mold surface can be adjusted, so that the drill bit can be smoothly fed in for cutting during processing, and the drill bit can be quickly retracted after processing to improve processing efficiency. Meanwhile, to achieve automatic lifting and positioning clamping of the mold, two mounting plates 8 are fixedly connected inside the operating table 1. A motor 9 is fixedly connected to the bottom of the mounting plate 8. When the motor 9 starts, it drives the rotating column 10 fixedly connected to the output end to start rotating. The top of the rotating column 10 has a threaded structure and is connected to the threaded hole opened at the center of the bottom of the lifting plate 11. When the motor 9 starts, it drives the rotating column 10 to rotate. Since there is a threaded engagement between the rotating column 10 and the lifting plate 11, and multiple limiting posts 12 fixedly connected to the bottom edge of the lifting plate 11 are slidably inserted into the guide holes inside the mounting plate 8, the limiting posts 12 restrict the degree of freedom of the lifting plate 11 to follow the rotation of the rotating column 10, forcing the lifting plate 11 to only move upward in the vertical direction. During the upward movement of the lifting plate 11, it will push the steam placed on top. The right cover mold is lifted smoothly, so that it is suspended on the surface of the operating table 1 to facilitate subsequent drilling operations and waste discharge. While the rotating column 10 drives the lifting plate 11 to rise, the rotating block 16 fixedly connected to the middle of the outer wall of the rotating column 10 rotates synchronously. The rotating block 16 drives the connecting rod 17 connected to the front and rear sides to swing through the hinge shaft. The other end of the connecting rod 17 is rotatably connected to the two movable tables 13 respectively. Since the top of the movable table 13 is slidably connected to the vertically fixed sliding column 15 through the slider 14, the sliding column 15 restricts the rotational freedom and vertical displacement freedom of the movable table 13, so that the swinging force of the connecting rod 17 is converted into a horizontal linear motion that pushes the movable table 13 along the arrangement direction of the sliding column 15, thereby realizing the synchronous control of the lifting action and the horizontal driving action by a single motor 9. As the motor 9 continues to rotate, the two movable platforms 13 move closer to each other under the pull of the connecting rod 17. Corner positioning wheels 18 are fixedly connected to the front and rear sides of the top of each movable platform 13. As the movable platforms 13 approach, the multiple corner positioning wheels 18 gradually conform to the corners and irregular edges of the right-side car cover mold. The rubber anti-slip layer on the outer wall of the corner positioning wheels 18 can tightly adhere to the mold surface, both preventing mold displacement during drilling by limiting and fixing the mold's position, and avoiding damage to the mold surface by the rigid clamps. When the motor... When the rotation of motor 9 stops, the mold remains in a raised and clamped state. At this time, the drilling machine 7 performs drilling operations. After drilling, the waste material falls directly from the waste material hole at the top of the lifting plate 11 into the waste material box 19 fixedly connected inside the operating table 1. After processing, the motor 9 reverses, the lifting plate 11 descends and resets, and the two movable tables 13 separate to the sides to release the mold, so as to remove the finished mold. Through the synergistic effect of the above mechanisms, this device effectively solves the problems of difficult positioning of automobile right cover mold and cumbersome waste material cleaning in the prior art.
