Description

Technical Field

[0001] This utility model relates to the field of servo press technology, specifically an intelligent servo press. Background Technology

[0002] In modern manufacturing, servo presses, as high-precision and intelligent pressure processing equipment, have been widely used in precision assembly and forming processes in fields such as automotive parts, electronic components, and medical devices.

[0003] According to CN202410950234.6, a high-precision servo press for metal stamping is disclosed. This technology discloses a technical solution including "a force-bearing frame, a conical self-centering press head device, and a reaction support device. The force-bearing frame serves as the base frame, and the conical self-centering press head device and the reaction support device are installed and fixed on the force-bearing frame to complete the stamping function. The conical self-centering press head device improves the repeatability accuracy of the servo press." It has the technical effects of "the servo press has a unique position when it resets, ensuring the positional accuracy at the start of stamping and preventing positional deviation during stamping contact. When the servo press moves downward, the reaction support device achieves relative movement between the reaction support point and the press head through mechanism transmission, ensuring stamping accuracy and improving equipment stability."

[0004] In existing servo presses, there is a problem of insufficient positioning accuracy in multi-station continuous pressing operations. Because traditional clamping mechanisms use a single drive source to control multiple fixed heads, it is difficult to achieve synchronous and accurate movement of multiple fixed heads, which makes it easy for the workpiece to have positional deviations during station transitions. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent servo press that achieves synchronous and precise positioning of multiple fixed heads, ensuring uniform distribution of clamping force; it completes complex motion trajectories through a single servo drive, improving positioning accuracy and production efficiency; its symmetrical layout eliminates eccentric forces, enhancing operational stability, and is suitable for continuous multi-station precision pressing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent servo press, comprising a frame, wherein a press mechanism is mounted on the frame for pressing workpieces, the press mechanism comprising:

[0007] The main components include a cam divider mounted on the front end of the top of the frame, with a turntable fixed to the output end above the cam divider;

[0008] The fixture assembly includes several positioning discs installed inside the outer edge of the turntable. Four circumferentially distributed sliders are fixed to the bottom of the positioning discs. A slide rail is slidably installed at the lower end of the sliders.

Four circumferentially distributed arc-shaped grooves are opened inside the disc, and the guide wheel is located inside the arc-shaped grooves. A drive assembly is provided on the positioning disc for driving the disc to rotate.

[0009] Preferably, the drive assembly further includes a mounting bracket fixed between the two ends of the bottom of the positioning disk, a servo motor is mounted on the bottom of the mounting bracket, and the output end of the servo motor is fixed to the disk.

[0010] Preferably, the main component further includes a frame fixed to the rear end of the top of the machine frame, an installation plate slidably installed inside the frame, a pressure head fixed at the lower end of the installation plate, a pressure sensor installed at the upper end of the installation plate, a servo press installed at the upper end of the frame, and the output end of the servo press fixed to the pressure sensor.

[0011] Preferably, the lower end of the fixing head and the upper end of the bracket are both provided with mounting holes, and the fixing head and the bracket are fixed together by bolts through the mounting holes.

[0014] Beneficial effects

[0015] This invention provides an intelligent servo press. Compared with the prior art, it has the following advantages:

[0016] 1. The servo motor drives the disc to rotate. The disc, through an arc-shaped groove, drives the guide wheel to slide along the inside of the arc-shaped groove. At the same time, the guide wheel also drives the slide rail to move radially along the slider. The slide rail, through the bracket, drives the fixed head to achieve a centrally symmetrical convergence or opening movement. The cam divider controls the rotation of the turntable and, in conjunction with the fixture assembly, ensures the positioning accuracy of multi-station conversion.

[0017] 2. The drive components are fully integrated into the bottom space of the positioning plate, which not only maintains the compactness of the fixture components, but also realizes precise adjustment of the rotation angle and speed of the disc through servo control, ensuring the smooth movement and repeatability of the workpiece positioning process. When it is necessary to change different models of fixed heads, the operation can be completed simply by loosening the bolts, which significantly improves the adaptability and flexibility of the fixture components.

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 Figure 1 - Figure 4 This utility model provides a technical solution: an intelligent servo press, including a frame 1, on which a press mechanism 2 is provided for pressing workpieces, the press mechanism 2 including:

[0025] The main component 21 includes a cam divider 211 mounted on the top front end of the frame 1, and a turntable 212 fixed at the output end above the cam divider 211;

[0026] The fixture assembly 22 includes several positioning disks 221 installed inside the outer edge of the turntable 212. Four circumferentially distributed sliders 222 are fixed to the bottom of the positioning disks 221. A slide rail 223 is slidably installed at the lower end of the sliders 222. A bracket 224 is fixed to the upper end of the slide rail 223. A fixing head 225 is installed at the upper end of the bracket 224. A guide wheel 226 is rotatably installed at the bottom of the slide rail 223. A disc 227 is rotatably installed in the middle of the lower end of the positioning disks 221. Four circumferentially distributed arc-shaped grooves 228 are opened inside the disc 227, and the guide wheel 226 is located inside the arc-shaped grooves 228. A drive assembly 229 is provided on the positioning disks 221 to drive the disc 227 to rotate.

[0027] In this embodiment, the output of the servo motor 2292 drives the disc 227 to rotate. The disc 227, through the arc groove 228, drives the guide wheel 226 to slide along the inside of the arc groove 228. At the same time, the guide wheel 226 also drives the slide rail 223 to move radially along the slider 222. The slide rail 223, through the bracket 224, drives the fixed head 225 to achieve a centrally symmetrical gathering or opening movement. The cam divider 211 controls the rotation of the turntable 212, and in conjunction with the fixture assembly 22, ensures the positioning accuracy of multi-station conversion. It is suitable for continuous pressing operations that require transfer between multiple stations, significantly improving production efficiency and positioning accuracy.

[0028] Specifically, the drive assembly 229 also includes a mounting bracket 2291 fixed between the two ends of the bottom of the positioning disk 221. A servo motor 2292 is mounted on the bottom of the mounting bracket 2291, and the output end of the servo motor 2292 is fixed to the disk 227.

[0029] In this embodiment, the drive component 229 is fully integrated into the bottom space of the positioning disk 221, which maintains the compactness of the fixture component 22 and achieves precise adjustment of the rotation angle and speed of the disk 227 through servo control, ensuring the smoothness of movement and repeatability of positioning during the workpiece positioning process.

[0030] Specifically, the main component 21 also includes a frame 213 fixed to the top rear end of the frame 1. An installation plate 214 is slidably installed inside the frame 213. A pressure head 215 is fixed to the lower end of the installation plate 214. A pressure sensor 216 is installed on the upper end of the installation plate 214. A servo press 217 is installed on the upper end of the frame 213, and the output end of the servo press 217 is fixed to the pressure sensor 216.

[0031] In this embodiment, the driving force of the servo press 217 is directly applied to the mounting plate 214 through the pressure sensor 216, forming a linear force transmission chain from power output to the working end of the press head 215.

[0032] Specifically, the lower end of the fixing head 225 and the upper end of the bracket 224 are both provided with mounting holes, and the fixing head 225 and the bracket 224 are fixed together with bolts through the mounting holes.

[0033] In this embodiment, when it is necessary to replace the fixing head 225 with a different model, the operation can be completed simply by loosening the bolts, which significantly improves the adaptability of the fixture assembly 22.

[0034] Specifically, the upper surface of the positioning disk 221 is provided with an anti-wear layer, and the anti-wear layer is a Teflon coating.

[0035] In this embodiment, the high lubricity of the Teflon coating significantly reduces the coefficient of friction between the workpiece and the positioning plate 221, preventing scratches from forming on the workpiece during the pressing process.

[0036] Specifically, a cover 3 is fixed to the upper end of the 1, and a control panel 4 is installed at the front end of the cover 3.

[0037] In this embodiment, the machine cover 3 effectively isolates the noise and splashes generated during the pressing process, while preventing operators from accidentally touching moving parts; the control panel 4 integrates a touch screen, an emergency stop button and status indicator lights, and is electrically connected to the servo press 217 and pressure sensor 216 via cables.

[0038] The working principle and usage process of this utility model are as follows: First, after the workpiece is placed on the positioning disk 221, the output end of the servo motor 2292 drives the disk 227 to rotate. The disk 227 drives the guide wheel 226 to slide along the inside of the arc groove 228 through the arc groove 228. At the same time, the guide wheel 226 also drives the slide rail 223 to move radially along the slider 222. The slide rail 223 drives the fixed head 225 to achieve a centrally symmetrical gathering or opening movement through the bracket 224. The cam divider 211 controls the rotation of the turntable 212 and, together with the fixture assembly 22, ensures the positioning accuracy of multi-station conversion. It is suitable for continuous pressing operations that need to be transferred between multiple stations, which significantly improves production efficiency and positioning accuracy.
