Description

Technical Field

[0001] This utility model belongs to the field of clamping equipment, and specifically relates to a CNC rotary clamping device for a machining center used in mold manufacturing. Background Technology

[0002] CNC clamping devices for mold manufacturing machining centers are important auxiliary equipment used in mold manufacturing machining centers. They are mainly used to fix the mold to ensure the accuracy and stability of the machining process. Currently, however, CNC clamping devices for mold manufacturing machining centers have certain limitations when dealing with complex machining needs. Due to their inherent structural characteristics, the devices are somewhat cumbersome in operation and have positioning limitations when performing multi-angle, multi-position machining adjustments on workpieces. This restricts the improvement of machining efficiency and accuracy when machining irregular molds or molds requiring multi-faceted machining. This mainly stems from the trade-off between the universality of machining scenarios and high efficiency in the device design. Some designs are conservative in integrating and expanding motion adjustment functions to ensure structural rigidity and stability. Conventional solutions involve pre-planning complex clamping processes and multiple clamping and positioning operations to achieve multi-faceted machining, or using tooling fixture combinations to complete positioning requirements for special angles. However, such methods inevitably introduce accumulated clamping errors, affecting machining accuracy. At the same time, multiple clamping and complex processes significantly extend the machining cycle, increase the uncertainty caused by frequent operations during machining, and reduce overall machining efficiency and quality stability. Therefore, a new structure is needed to solve the above technical problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a CNC rotary clamping device for machining centers used in mold manufacturing, so as to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a CNC rotary clamping device for a machining center for mold manufacturing, comprising: a rotating component, a shifting component, and a clamping component. The upper surface of the rotating component is provided with four sets of shifting components in a cross structure. The upper surface of the shifting component is provided with clamping components for clamping the mold. The number of clamping components matches the number of shifting components. The rotating component includes a rotating member for controlling the rotation of the rotating plate. The shifting component includes a moving member for controlling the movement of the slider.

The end of the rotating shaft away from the rotating seat is connected to the center of the lower surface of the rotating plate. The rotating plate has a disc structure. A triangular reinforcing plate is installed between the outer surface of the rotating shaft and the lower surface of the rotating plate. In use, the rotating component in the rotating assembly can control the rotation of the rotating plate, enabling the workpiece to quickly switch to different directions without re-clamping. This allows the machining center's cutting tools to process multiple surfaces of the workpiece, reducing clamping time and auxiliary time, thereby improving processing efficiency.

[0007] In a preferred embodiment, the moving component includes a base plate, a vertical plate, a limiting rod, a lead screw body, and a lead screw motor.

[0010] In a preferred embodiment, a drive motor is installed on the inner surface of the connecting plate and below the mounting block. The output shaft of the drive motor passes through the lower surface of the mounting block. A drive rod is rotatably mounted on the center of the upper surface of the mounting block through the output shaft of the drive motor. Connecting rods are hinged to the inner surfaces of the two clamping rods. In use, the four sets of shifting components mounted in a cross structure on the rotating assembly can move flexibly in two mutually perpendicular directions. This allows the mold to be adjusted in position on the horizontal plane, making it convenient to accurately move different parts of the mold under the processing tool without the need for frequent manual re-clamping and adjustment of the mold position, greatly improving the convenience and efficiency of processing.

[0011] In a preferred embodiment, the end of the connecting rod away from the clamping rod is hinged to the driving rod, and the inner surface of the clamping rod is bonded with anti-slip rubber.

[0023] 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.

[0024] Please see Figures 1 to 5 As the first embodiment of this utility model: a CNC rotary clamping device for a machining center for mold manufacturing, comprising: a rotary assembly 100, a shifting assembly 200 and a clamping assembly 300. The upper surface of the rotary assembly 100 is provided with four sets of shifting assemblies 200 in a cross structure. The upper surface of the shifting assembly 200 is provided with clamping assemblies 300 for clamping the mold. The number of clamping assemblies 300 matches the number of shifting assemblies 200. The rotary assembly 100 includes a rotating component for controlling the rotation of the rotary plate 110. The shifting assembly 200 includes a moving component for controlling the movement of the slider 260. The clamping assembly 300 includes a mounting block 330 for mounting the clamping rod 340.

[0025] The rotating component includes a mounting plate 130, a rotating seat 150, a rotating shaft 160, a reinforcing plate 120, and a rotating motor 140. A bolt is installed through each of the four corners of the upper surface of the mounting plate 130. A rotating seat 150 with a U-shaped structure is installed at the center of the upper surface of the mounting plate 130. The rotating motor 140 is installed on the lower surface of the rotating shaft 160 via the mounting plate 130.

[0026] A rotating shaft 160 is rotatably mounted on the upper surface of the rotating seat 150. The output shaft of the rotating motor 140 is connected to the rotating shaft 160. The end of the rotating shaft 160 away from the rotating seat 150 is connected to the center of the lower surface of the rotating plate 110. The rotating plate 110 has a disc structure. A reinforcing plate 120 with a triangular structure is installed between the outer surface of the rotating shaft 160 and the lower surface of the rotating plate 110.

[0027] In use, the user prepares the mold to be manufactured and then clamps and fixes the mold inside the clamping assembly 300. After the clamping assembly 300 fixes the mold, the user can adjust the position of the clamping assembly 300 using the shifting assembly 200 to place it in a suitable position for subsequent processing. After the mold is clamped and fixed, the user can then perform processing operations on the mold. During operation, after one side of the mold is processed, the user can start the rotary motor 140 on the upper surface of the mounting base, causing the output shaft of the rotary motor 140 to drive the rotating shaft 160 to rotate (the rotary motor 140 is a stepper motor, which is existing technology, and the specific rotation speed and number of revolutions are...). The specific working principle and structure will not be elaborated here, but can be selected according to the actual situation. When the rotating shaft 160 rotates, it will drive the rotating plate 110 connected to it to rotate, thereby rotating the clamping component 300 installed on the upper surface of the rotating plate 110, and finally achieving the effect of rotating the clamped mold. At this time, the position of the mold can be adjusted by the shifting component 200, and then the mold can be processed, which is convenient for users. Since the rotating component in the rotating component 100 can control the rotation of the rotating plate 110 during use, the workpiece can be quickly switched to different directions without re-clamping. This allows the tool of the machining center to process multiple sides of the workpiece, reducing clamping time and auxiliary time, thereby improving processing efficiency.

[0028] Please see Figures 1 to 5 As a second embodiment of the present utility model: based on the description in the above embodiments, the moving part further includes a base plate 210, a vertical plate 220, a limiting rod 240, a lead screw body 250 and a lead screw motor 230. The vertical plate 220 is installed on both sides of the upper surface of the base plate 210. Two limiting rods 240 are symmetrically installed between the two vertical plates 220. The lead screw body 250 is rotatably installed between the two limiting rods 240 through the vertical plate 220.

[0029] A lead screw motor 230 is installed on the rear surface of the rear upright plate 220. The output shaft of the lead screw motor 230 is rotatably connected to the lead screw body 250 through a coupling. A slider 260 is installed through the limit rod 240 and the outer surface of the lead screw body 250.

[0030] A connecting plate 310 is integrally formed on the lower surface of the mounting block 330. The side surface of the connecting plate 310 away from the mounting block 330 is connected to the upper surface of the slider 260. Slide grooves 331 are symmetrically opened on the upper surface of the mounting block 330. A clamping rod 340 is slidably installed in each of the two slide grooves 331.

[0031] A drive motor 320 is installed on the inner surface of the connecting plate 310 and below the mounting block 330. The output shaft of the drive motor 320 passes through the lower surface of the mounting block 330. A drive rod 321 is rotatably installed at the center of the upper surface of the mounting block 330 through the output shaft of the drive motor 320. A connecting rod 322 is hinged to the inner surface of the two clamping rods 340.

[0032] The end of the connecting rod 322 away from the clamping rod 340 is hinged to the drive rod 321, and the inner surface of the clamping rod 340 is glued with anti-slip rubber.

[0033] In use, when the mold is clamped by the clamping assembly 300 through the operation steps of the first embodiment, the drive motor 320 on the lower surface of the mounting block 330 is first started (the drive motor 320 is a forward and reverse motor, which is existing technology, and the model can be selected from existing market equipment; the specific working principle and structure are not described here). When the drive motor 320 rotates forward, the output shaft of the drive motor 320 will drive the drive rod 321 to rotate. Since the drive rod 321 is hinged to the connecting rod 322, the connecting rod 322 will be driven to rotate. Since the connecting rod 322 is hinged to the clamping rod 340, the connecting rod 322 will drive the clamping rod 340 to move along the slide groove 331 on the upper surface of the mounting block 330, thereby causing the two clamping rods 340 to move towards each other, thus clamping the mold. Similarly, by performing the above reverse operation, the two clamping rods 340 will move away from each other, thereby causing the mold to lose the clamping rods 340. The mold can be removed by clamping. After clamping, the user can start the lead screw motor 230 to drive the lead screw body 250 to rotate (the lead screw motor 230 drives the motor 320 in the same way). When the lead screw body 250 rotates, it will drive the slider 260 connected to its outer surface to move forward and backward. The slider 260 moves along the two limit rods 240 and the lead screw body 250, thereby driving the clamping assembly 300 on the upper surface of the slider 260 to move forward and backward. This allows the position of the clamping assembly 300 to be adjusted. Since the four sets of shifting assemblies 200 installed in a cross structure on the rotating assembly 100 can move flexibly in two mutually perpendicular directions, the position of the mold can be adjusted on the horizontal plane. This makes it easy to accurately move different parts of the mold to the underside of the processing tool without the need for frequent manual re-clamping and adjustment of the mold position, which greatly improves the convenience and efficiency of processing.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
