Description

Technical Field

[0001] This application relates to the technical field of milling machine equipment, and in particular to a milling machine drilling device for mold processing. Background Technology

[0002] When using existing milling machine drilling devices for mold processing, the mold is usually fixed to the worktable of the drilling device, and the drilling head on the drilling device performs drilling processing on the mold.

[0003] The existing publication number CN202517276U, entitled "A Drilling and Milling Machine," describes a drilling and milling machine. A guide column is vertically installed between the machine frame and the crossbeam at the top of the frame. A slider is mounted on the guide column, and the slider is driven by a hydraulic cylinder fixed to the crossbeam to slide up and down along the guide column. A drilling and milling device is mounted on the slider, with a spindle rotatably connected to its center. A drill bit or milling cutter is mounted at the lower end of the spindle, and a pulley is fixed at the upper end. A first drive motor that outputs torque to the pulley is mounted on the slider on one side of the pulley. A worktable is rotatably mounted on the frame below the drill bit or milling cutter, and a workpiece fixture is fixed on the worktable. A second drive motor at the bottom of the worktable drives the worktable to rotate. The advantages are: when the drilling device of this invention is working, the worktable simultaneously causes the workpiece to rotate in the opposite direction, effectively preventing the hole position from deviating from the center of the drill bit; the speed of the drive motor is reduced by the pulley, resulting in low cost and suitability for drilling and milling operations on various types of steel.

[0004] Regarding the aforementioned technologies, the inventors discovered that when milling a grinding wheel to drill holes, the completed mold needs to be manually removed from the milling machine table. When removing the mold, it is located on the drilling station, and the presence of the drilling tool can cause injury to the person holding the mold, posing a safety hazard to the workers handling the material. Utility Model Content

[0005] In order to overcome the problem that when drilling molds on existing milling machines, the finished molds need to be manually removed from the milling machine table. When removing the molds, they are located at the drilling station, and the presence of the drilling tool can cause injury to the person holding the mold, posing a safety hazard to the workers. This application provides a milling machine drilling device for mold processing.

[0006] The milling machine drilling device for mold processing provided in this application adopts the following technical solution:

[0007] A milling machine drilling device for mold processing includes a worktable, a processing frame, a material support component, and a drilling component. The processing frame is vertically fixed on the top surface of the worktable, and the drilling component is vertically arranged on the upper part of the rear end face of the processing frame. The top surface of the processing frame has an opening for a material drop port, and hole frames are fixed on the symmetrical vertical end faces on both sides of the top surface of the processing frame. The material support component includes a material support plate, which is arranged on the side of the hole frame close to the processing frame and is used to support the mold. A slide bar frame is horizontally slidably assembled on the hole frame, and one end of the slide bar frame is fixed to the material support plate. Multiple rollers are horizontally rotatably connected to the lower inner side of the processing frame.

[0008] By adopting the above technical solution, the mold that needs to be drilled is placed above the processing frame. Then, the sliding rod frame on both sides of the top surface of the processing frame slides horizontally, driving the material support plate to move towards the mold, squeezing and clamping the mold to maintain stability during drilling. Then, the drilling tool is used to drill the mold downwards. After the drilling is completed, the sliding rod frame slides on the processing frame, so that the material support plate no longer supports the mold. The mold without support falls down from the material outlet. The mold is supported by multiple rollers at the bottom of the processing frame, pulling the mold to slide on the rollers. Thus, when the mold is unloaded, it moves horizontally from the bottom side of the processing frame, away from the drilling tool, avoiding injury to the person holding the mold and ensuring the safety of the material handling personnel.

[0009] Optionally, a dual-head motor is horizontally fixed to the top of the front end face of the frame, and the output ends of both motors are horizontally fixed with screws.

[0010] By adopting the above technical solution, in order to drive the material support plate to move laterally and support the mold, a dual-head motor is started to drive the screw to rotate, and the screw drives the material support plate to squeeze and clamp the mold to maintain stability.

[0011] Optionally, a screw hole block is vertically fixed to the other end of the slide block, and the screw hole block is assembled with the screw thread through it.

[0012] By adopting the above technical solution, the screw rotation thread drives the screw hole block at the end of the slide block, and the thread drives the slide block to slide on the hole frame, which drives the material support plate to squeeze and hold the mold to maintain stability for drilling processing.

[0013] Optionally, a spring is horizontally fixed on the slide bar bracket, and the two ends of the spring are fixed to the slide bar bracket and the hole frame, respectively.

[0014] By adopting the above technical solution, the slide bar frame moves laterally on the hole frame. Under the action of spring deformation force, the slide bar frame is moved laterally, which in turn drives the material support plate to support the mold and maintain the stability of the drilling process.

[0015] Optionally, a pusher frame is horizontally fixed to the bottom of the rear end face of the processing frame, a pusher hydraulic rod is horizontally fixed to the middle of the pusher frame, and a pusher plate is vertically fixed to the output end of the pusher hydraulic rod.

[0016] By adopting the above technical solution, the finished mold falls to the bottom of the rear end face of the processing frame, and the pusher hydraulic rod on the pusher frame is activated to extend, which drives the pusher plate to move laterally and push the mold to be supported by multiple rollers at the bottom of the processing frame, and slide out, which is convenient for material removal later.

[0017] Optionally, the drilling component includes a guide rod frame, a sliding frame, and a hole-opening slider. The guide rod frame is vertically fixed to the top of the rear end face of the machining frame, and a sliding frame is horizontally arranged at the front of the guide rod frame. The sliding frame is vertically slidably assembled on the guide rod frame, and a hole-opening slider is horizontally slidably assembled in the sliding frame.

[0018] By adopting the above technical solution, when the drilling part processes the mold, it drives the slide frame to slide vertically on the guide rod frame, which facilitates the vertical adjustment of the drilling position. The drilling slider is equipped with a drilling rod, and the drilling slider moves horizontally in the slide frame to adjust the drilling position of the mold.

[0019] Optionally, a perforated strip is horizontally fixed on the rear end face of the slide frame, and the perforated strip is vertically slidably assembled on the guide rod frame. A downward hydraulic rod is vertically fixed on the top surface of the guide rod frame, and the output end of the downward hydraulic rod is fixed to the perforated strip.

[0020] By adopting the above technical solution, the downward hydraulic rod is activated to extend and push the hole strip on the slide frame to slide vertically on the guide rod frame, which facilitates the adjustment of the drilling position in the vertical direction.

[0021] Optionally, a horizontally fixed transverse hydraulic rod is provided on the front end face of the slide frame.

[0022] By adopting the above technical solution, the horizontal hydraulic rod extends and pushes the opening slider to move horizontally in the slide frame, thereby adjusting the opening position of the mold.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the mold requiring drilling is placed above the processing frame, and then the sliding rod frame on both sides of the top surface of the processing frame slides horizontally, driving the material support plate to move towards the mold, squeezing and clamping the mold to maintain stability during drilling. Then, the drilling component is used to drill the mold downwards. After drilling is completed, the sliding rod frame slides on the processing frame, so that the material support plate no longer supports the mold. The mold without support falls downwards from the discharge port. The mold is supported by multiple rollers at the bottom of the processing frame, pulling the mold to slide on the multiple rollers. Thus, when the mold is unloaded, it moves horizontally from the bottom side of the processing frame, thereby moving away from the drilling tool, avoiding injury to the person holding the mold, and ensuring the safety of the material handling personnel.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a milling machine drilling apparatus for mold processing. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A milling machine drilling device for mold processing includes a worktable 1, a processing frame 2, a material support 3, and a drilling component 4. The processing frame 2 is vertically fixed on the top surface of the worktable 1, and the drilling component 4 is vertically arranged on the upper part of the rear end face of the processing frame 2. The top surface of the processing frame 2 has an opening for a material drop port 21, and hole frames 22 are fixed on the symmetrical vertical end faces on both sides of the top surface of the processing frame 2. The material support 3 includes a material support plate 31, which is arranged on the side of the hole frame 22 close to the processing frame 2 and is used to support the mold. A sliding rod frame 32 is horizontally slidably assembled on the hole frame 22, and one end of the sliding rod frame 32 is fixed on the material support plate 31. Multiple rollers 26 are horizontally rotatably connected to the lower side of the interior of the processing frame 2.

[0032] By adopting the above technical solution, the mold that needs to be drilled is placed above the processing frame 2. Then, the sliding rod frame 32 on the two side holes 22 on the top surface of the processing frame 2 slides horizontally, driving the material support plate 31 to move towards the mold, squeezing and clamping the mold to maintain stability during drilling. Then, the drilling part 4 drills the mold downwards. After the drilling is completed, the sliding rod frame 32 slides on the processing frame 2, so that the material support plate 31 no longer supports the mold. The mold without support falls down from the drop port 21. The mold is supported by multiple rollers 26 at the bottom of the processing frame 2, pulling the mold to slide on the multiple rollers 26. Thus, when the mold is unloaded, it moves horizontally from the bottom side of the processing frame 2, away from the drilling tool, avoiding injury to the person holding the mold and ensuring the safety of the material handling personnel.

[0033] Reference Figure 3 and Figure 4 A dual-head motor 23 is horizontally fixed to the top of the front end face of the hole frame 22, and screws 24 are horizontally fixed to the output ends of both motors 23. To drive the material support plate 31 to move laterally and support the mold, the dual-head motor 23 is started to drive the screws 24 to rotate. The screws 24 drive the material support plate 31 to press and clamp the mold to maintain stability. A screw hole block 34 is vertically fixed to the other end of the slide bar frame 32, and the screw hole block 34 is threadedly connected to the screw 24. The rotation of the screw 24 drives the screw hole block 34 at the end of the slide bar frame 32, which in turn drives the slide bar frame 32 to slide on the hole frame 22, causing the material support plate 31 to press and clamp the mold to maintain stability for drilling processing.

[0034] Reference Figure 3 and Figure 4 A spring 33 is horizontally fixed on the slide bar frame 32, with both ends of the spring 33 fixed to the slide bar frame 32 and the hole frame 22, respectively. The slide bar frame 32 moves laterally on the hole frame 22. Under the deformation force of the spring 33, the slide bar frame 32 slides laterally, which in turn drives the material support plate 31 to support the mold and maintain the stability of the drilling process. A pusher frame 25 is horizontally fixed at the bottom of the rear end face of the processing frame 2. A pusher hydraulic rod 251 is horizontally fixed in the middle of the pusher frame 25, and a pusher plate 252 is vertically fixed at the output end of the pusher hydraulic rod 251. After the mold is processed, it falls to the bottom of the rear end face of the processing frame 2. The pusher hydraulic rod 251 on the pusher frame 25 is activated to extend, which drives the pusher plate 252 to move laterally and push the mold to be supported by multiple rollers 26 at the bottom of the processing frame 2, and slide out for easy material removal later.

[0035] Reference Figure 5The drilling component 4 includes a guide rod frame 41, a sliding frame 44, and an opening slider 45. The guide rod frame 41 is vertically fixed to the top of the rear end face of the processing frame 2, and the sliding frame 44 is horizontally arranged at the front of the guide rod frame 41. The sliding frame 44 is vertically slidably assembled on the guide rod frame 41, and the opening slider 45 is horizontally slidably assembled in the sliding frame 44. When the drilling component 4 processes the mold, it drives the sliding frame 44 to slide vertically on the guide rod frame 41, which facilitates the vertical adjustment of the drilling position. A drilling rod is installed on the opening slider 45, and the opening slider 45 moves laterally in the sliding frame 44 to adjust the opening position of the mold. A perforated strip 43 is horizontally fixed on the rear end face of the sliding frame 44, and the perforated strip 43 is vertically slidably assembled on the guide rod frame 41. A downward hydraulic rod 42 is vertically fixed on the top surface of the guide rod frame 41, and the output end of the downward hydraulic rod 42 is fixed to the perforated strip 43. The downward hydraulic rod 42 extends and pushes the perforated strip 43 on the slide frame 44 to slide vertically on the guide rod frame 41, facilitating vertical adjustment of the drilling position. A horizontally fixed transverse hydraulic rod 46 is fixed on the front end face of the slide frame 44. The transverse hydraulic rod 46 extends and pushes the opening slider 45 to move laterally within the slide frame 44, adjusting the opening position of the mold.

[0036] The implementation principle of the milling machine drilling device for mold processing in this application embodiment is as follows: During use, the mold to be drilled is placed above the processing frame 2. Then, the slide rod brackets 32 on the two side hole frames 22 on the top surface of the processing frame 2 slide horizontally. To drive the material support plate 31 to move laterally and support the mold, the double-head motor 23 is started to drive the screw 24 to rotate, causing the material support plate 31 to move towards the mold. The screw 24 rotates, threadedly driving the screw hole block 34 at the end of the slide rod bracket 32. The threaded drive of the slide rod bracket 32 ​​slides on the hole frame 22, causing the material support plate 31 to press and clamp the mold to maintain stability. Pressing and clamping the mold maintains stability during drilling. Then, when the drilling part 4 processes the mold, the downward-pressing hydraulic rod 42 extends and pushes the hole strip 43 on the slide frame 44 to slide vertically on the guide rod bracket 41, facilitating vertical adjustment of the drilling position. A drilling rod is installed on the hole-opening slider 45. The horizontal hydraulic rod 46 extends and pushes the hole-opening slider 45 to move horizontally in the slide frame 44 to adjust the hole position of the mold. The drilling part 4 is used to drill the mold downward. After the drilling is completed, the slide rod frame 32 slides on the processing frame 2, so that the material support plate 31 no longer supports the mold. The mold without support falls down from the drop port 21. The mold is supported by multiple rollers 26 at the bottom of the processing frame 2. After the processing is completed, the mold falls to the bottom of the rear end face of the processing frame 2. The pusher hydraulic rod 251 on the pusher frame 25 extends and drives the pusher plate 252 to move horizontally and push the mold to be supported by multiple rollers 26 at the bottom of the processing frame 2. The mold slides out and pulls the mold to slide on the multiple rollers 26. Thus, when the mold is unloaded, it moves horizontally from the bottom side of the processing frame 2, thereby moving away from the drilling tool.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
