Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically a gantry milling machine. Background Technology

[0002] A gantry milling machine, or simply gantry milling machine, is a type of milling machine with a gantry frame and a horizontal long bed. Due to its high rigidity and large machining range, gantry milling machines are widely used in the following fields: machinery manufacturing, aerospace, automotive industry, and mold manufacturing. Some existing gantry milling machines use a fixed cutter angle for workpiece milling, while others use a design without protective mechanisms to protect the workpiece during milling and prevent splashing. These latter types of gantry milling machines have some problems. For example, the fixed cutter angle limits the applicable range of workpiece milling and affects the milling effect. The lack of protective mechanisms means the working milling process is completely exposed, which may affect the safety of the equipment due to flying debris and also affect the service life of other mechanisms. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a gantry milling machine that can adjust the milling angle of the milling cutter and protect the milling process to avoid chip splashing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gantry milling machine, including a milling table and a retractable protective mechanism;

The lower end of the drive shaft is fixedly connected to a milling cutter. A working chamber is provided at the lower end of the milling table.

[0006] Retractable protective mechanism: It is located between the milling table and the working chamber, which can adjust the milling angle of the milling cutter and protect the milling process to prevent debris from flying.

[0007] Furthermore, a work frame is fixedly connected to the upper end of the milling table, and a controller is provided at the lower end of the left side surface of the work frame. The input end of the controller is electrically connected to an external power supply to control various electrical appliances.

[0008] Furthermore, the adjustable milling mechanism also includes a first motor, a drive wheel, a second motor, and a driven wheel. The first motor is located at the upper end of the bracket.

The lower end of the output shaft of the second motor is fixedly connected to the upper end of the drive shaft. The input ends of the first motor and the second motor are electrically connected to the output end of the controller to provide driving force for the rotation and angle adjustment of the milling cutter.

[0009] Furthermore, the retractable protective mechanism includes a protective plate, a threaded cylinder, a horizontal plate, and a screw. The threaded cylinder is rotatably connected to the lower end of the working chamber. Sliding openings are provided at both the front and rear ends of the milling table.

The middle part of the screw is threadedly connected to the inside of the threaded cylinder to realize the release and retraction of the protective plate.

[0010] Furthermore, the retractable protective mechanism also includes a worm gear, a worm, a motor, and guide posts. The worm gear is fixedly connected to the upper end of the outer surface of the threaded cylinder. The motor is located at the rear end of the bottom wall of the working chamber. The left end of the output shaft of the motor is fixedly connected to the worm, which meshes with the worm gear.

[0014] 1. Through the transmission belt, the drive wheel and driven wheel rotate synchronously, and then the adjusting disc rotates through the rotating shaft, ultimately realizing the lateral angle adjustment of the milling cutter. This allows the milling cutter to meet the different milling requirements of different workpieces at different positions, greatly improving the workpiece milling application range of the gantry milling machine.

[0015] 2. The screw moves upward by rotating the threaded cylinder, which in turn moves the protective plate upward. The protective plate slides out through the corresponding slide, thus protecting the milling area and preventing debris from flying. This effectively prevents debris from affecting the working coordination of other mechanisms and improves the milling safety of the gantry milling machine. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a gantry milling machine, including a milling table 1 and a retractable protective mechanism 5;

[0023] Milling table 1: An adjustable milling mechanism 4 is provided on its upper end. The adjustable milling mechanism 4 includes a bracket 44, an adjusting plate 45, and a milling cutter 47. The bracket 44 is located on the upper end of the milling table 1. The lower end of the bracket 44 is rotatably connected to symmetrically distributed rotating shafts. The adjusting plate 45 is fixedly connected between the two rotating shafts. The lower end of the adjusting plate 45 is rotatably connected to a drive shaft. The lower end of the drive shaft is fixedly connected to the milling cutter 47. The adjustable milling mechanism 4 also includes a first motor 41, a drive wheel 42, a second motor 43, and a driven wheel 46. The first motor 41 is located on the upper end of the bracket 1. At the upper end of the frame 44, a drive wheel 42 is fixedly connected to the front end of the output shaft of motor 1 41, and a driven wheel 46 is fixedly connected to the front end of the rotating shaft on the front side. The drive wheel 42 and the driven wheel 46 are connected by a transmission belt. A motor 2 43 is installed at the upper end of the adjusting disc 45. The lower end of the output shaft of motor 2 43 is fixedly connected to the upper end of the drive shaft. The input ends of motor 1 41 and motor 2 43 are electrically connected to the output end of controller 12. A working chamber 2 is installed at the lower end of the milling table 1, and a working frame 3 is fixedly connected to the upper end of the milling table 1. The left side of the working frame 3... A controller 12 is installed at the lower end of the side surface. The input terminal of the controller 12 is electrically connected to an external power supply. The controller 12 enables the operation of the motor 41. The output shaft of the motor 41 rotates, driving the drive wheel 42 to rotate. The drive wheel 42 drives the driven wheel 46 to rotate via a transmission belt. The driven wheel 46 rotates, driving the front shaft to rotate, thereby rotating the adjusting disc 45. The rotation of the adjusting disc 45 drives the milling cutter 47 to rotate, thereby adjusting the lateral angle of the milling cutter 47. When the milling cutter 47 reaches the desired position, the controller 12 shuts off. The motor 41 is shut down and the motor 43 is turned on. The output shaft of the motor 43 rotates and drives the drive shaft to rotate. The drive shaft rotates and the milling cutter 47 rotates. Then, the external air pump makes the pneumatic guide rail 6 run. The sliding seat of the pneumatic guide rail 6 moves laterally and drives the telescopic cylinder 7 to move laterally, which in turn drives the adjustable milling mechanism 4 to move laterally. At the same time, the external air pump makes the piston rod of the telescopic cylinder 7 extend. The extension of the piston rod of the telescopic cylinder 7 pushes the bracket 44 to move down, which in turn makes the milling cutter 47 move down, thus realizing the milling work of the workpiece.

[0024] Retractable protective mechanism 5: Located between milling table 1 and working chamber 2, retractable protective mechanism 5 includes protective plate 51, threaded cylinder 52, horizontal plate 54, and screw 58. Threaded cylinder 52 is rotatably connected to the lower end of working chamber 2. Sliding openings are provided at both the front and rear ends of milling table 1, and protective plates 51 are slidably connected inside the sliding openings. A horizontal plate 54 is fixedly connected to the lower end between two protective plates 51, and a screw 58 is fixedly connected to the lower end of the horizontal plate 54. The middle part of the screw 58 is threadedly connected to the inside of the threaded cylinder 52. Retractable protective mechanism 5 also includes worm gear 53, worm 55, motor 56, and guide post 57. Worm gear 53 is fixedly connected to the upper end of the outer surface of threaded cylinder 52. Motor 56 is located at the rear end of the bottom wall of working chamber 2, and the output shaft of motor 56... A worm 55 is fixedly connected to the left end, and the worm 55 and the worm wheel 53 are meshed together. Guide posts 57 are symmetrically fixedly connected to the front and rear ends of the horizontal plate 54. The lower end of the working chamber 2 is provided with symmetrically distributed guide ports. The guide posts 57 are all slidably connected to the interior of the vertically adjacent guide ports. The input end of the motor 3 56 is electrically connected to the output end of the controller 12. The controller 12 realizes the operation of the motor 3 56. The output shaft of the motor 3 56 rotates, which drives the worm 55 to rotate, thereby realizing the rotation of the worm wheel 53. The rotation of the worm wheel 53 drives the threaded cylinder 52 to rotate. The rotation of the threaded cylinder 52 causes the screw 58 to move upward, which in turn pushes the two protective plates 51 upward through the horizontal plate 54. The protective plates 51 slide out through the corresponding sliding ports, realizing the release of the protective plates 51 and protecting the milling area.

[0025] Among them: the upper end of the work frame 3 is provided with a pneumatic guide rail 6, the upper end of the sliding seat of the pneumatic guide rail 6 is provided with a telescopic cylinder 7, the lower end of the piston rod of the telescopic cylinder 7 is fixedly connected to the upper end of the bracket 44, the pneumatic guide rail 6 and the telescopic cylinder 7 are both connected to the air outlet of an external air pump through an air pipe, and the input end of the external air pump is electrically connected to the output end of the controller 12.

[0026] Among them: telescopic cylinders 2 and 9 are provided at both ends of the work frame 3. The piston rod of telescopic cylinder 2 and 9 is fixedly connected to a clamping plate 8 at the end near the center of the milling table 1. Telescopic cylinder 2 and 9 are connected to the air outlet of an external air pump through air pipe 2. The milling table 1 is provided with evenly distributed grooves 10 inside. The inside of each groove 10 is rotatably connected to an auxiliary wheel 11.

[0027] The working principle of the gantry milling machine provided by this utility model is as follows: During operation, the operator first places the milling table 1, the work chamber 2, and other mechanisms stably in the horizontal working area. After stable placement, the operator places the workpiece to be milled on the upper end of the milling table 1. With the assistance of the auxiliary wheel 11, the workpiece moves to the center position of the upper surface of the milling table 1. Then, the operator activates the external air pump through the controller 12. The external air pump activates two telescopic cylinders 9. The piston rods of the telescopic cylinders 9 extend, and the extension of the piston rods of the telescopic cylinders 9 pushes the corresponding clamping plates 8 to move towards the center of the milling table 1, thereby achieving stable clamping of the workpiece. After stable clamping, the operator activates the motor 41 through the controller 12. The output shaft of the motor 41 rotates, driving the drive wheel 42 to rotate. The drive wheel 42 drives the driven wheel 46 to rotate through the transmission belt. The rotation of the driven wheel 46 drives the front rotating shaft to rotate, thereby achieving the rotation of the adjusting plate 45. The rotation of the adjusting plate 45 drives the milling cutter 47 to rotate, thereby achieving the lateral angle adjustment of the milling cutter 47. After adjustment, when the milling cutter 47 reaches the desired position, the operator shuts off motor 1 41 and starts motor 2 43 via controller 12. The output shaft of motor 2 43 rotates, driving the drive shaft to rotate, which in turn drives the milling cutter 47 to rotate. Then, an external air pump starts the pneumatic guide rail 6. The sliding seat of the pneumatic guide rail 6 moves laterally, which drives the telescopic cylinder 1 7 to move laterally, which in turn drives the adjustable milling mechanism 4 to move laterally. At the same time, the external air pump extends the piston rod of the telescopic cylinder 1 7, which pushes the bracket 44 down, thus moving the milling cutter 47 down and completing the milling operation. Simultaneously, controller 12 starts motor 3 56. The output shaft of motor 3 56 rotates, driving the worm gear 55 to rotate, which in turn drives the worm wheel 53 to rotate. The worm wheel 53 rotates, driving the threaded cylinder 52 to rotate, which causes the screw 58 to move up. This, in turn, pushes the two protective plates 51 up through the horizontal plate 54. The protective plates 51 slide out through their corresponding slots, releasing the protective plates 51 and protecting the milling area.

[0028] It is worth noting that the controller 12 disclosed in the above embodiments controls the operation of motor 1 41, motor 2 43, motor 3 56 and external air pump using methods commonly used in the prior art.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
