Description

Technical Field

[0001] This utility model relates to the field of CNC machining center technology, and in particular to a liquid forging automotive swing arm CNC machining center device. Background Technology

[0002] Liquid forged automotive control arms are key automotive components formed through liquid forging processes. Their design combines the advantages of both casting and forging, enabling the one-time forming of complex U-shaped structures. This significantly reduces material waste and improves mechanical properties. CNC machining centers can handle high-hardness materials and achieve micron-level precision through small-diameter tools and high feed rates, directly completing the finishing process after heat treatment and avoiding the inefficient steps of traditional electrical discharge machining or manual polishing.

[0003] Traditional CNC machining centers process liquid forged automotive swing arms by positioning the workpiece using fixtures and coordinate measuring systems, employing multi-axis linkage technology, and using carbide tools to complete roughing, semi-finishing, and finishing in stages. High-speed milling is used to eliminate local excess material in the liquid forgings, and the tools are then dressed.

[0004] When machining liquid forged automotive swing arms, traditional CNC machining centers often encounter problems with traditional fixtures due to the complex geometry of the liquid forgings. These fixtures are poorly adaptable, time-consuming to adjust, and have limited positioning repeatability. Furthermore, the high temperatures generated during machining can easily cause tool overheating, leading to micro-cracks on the workpiece surface. At the same time, high-temperature thermal stress can damage the dense grain structure of the liquid forgings, affecting fatigue life. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a CNC machining center device for liquid forged automotive swing arms, which aims to improve the problems of poor adaptability of traditional fixtures due to the complex geometric features of liquid forged parts, time-consuming adjustment and limited positioning repeatability when machining liquid forged automotive swing arms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid forging automotive swing arm CNC machining center device, including a base, a housing fixedly connected to the top of the base, and a clamping assembly disposed inside the housing;

[0007] The clamping assembly includes a clamp, inside which a rotating shaft is fixedly connected. A connecting rod and a connecting rod rotatably connect to the outer wall of the rotating shaft. A rotating shaft and a fixed post are fixedly connected to one end of each connecting rod. A slider is fixedly connected to the end of the fixed post. A limit block is slidably connected to the outer wall of the slider. A fixed plate is fixedly connected to the outer wall of the limit block. A post is fixedly connected to the bottom of the fixed plate. Two guide rails are slidably connected to the outer wall of the fixed plate. A base is provided between the two guide rails. A cylinder is fixedly connected to the upper surface of the base. A push rod is fixedly connected to the output end of the cylinder. A rotating shaft is fixedly connected to the inner wall of the base. A connecting rod is rotatably connected to the outer wall of the rotating shaft.

[0008] Furthermore, a motor is installed on the top of the housing, and a transmission module is installed at the output end of the motor. A blade is fixedly connected to one end of the transmission module, and a high-pressure nozzle is installed on one side of the outer wall of the blade. A water outlet pipe is fixedly connected to one end of the high-pressure nozzle, and a water pump is fixedly connected to one end of the water outlet pipe. A water inlet pipe is fixedly connected to the input end of the water pump, and a water tank is fixedly connected to one end of the water inlet pipe. A filter screen is slidably connected inside the water tank, and a guide pipe is installed above the water tank. One end of the guide pipe is fixedly connected to the outer wall of the base, and a guide groove is installed inside the base. A handle is fixedly connected to the outer wall of the filter screen, and a button is installed on one side of the outer wall of the water tank. A fixing post three is fixedly connected to the outer wall of the button, and a locking block is fixedly connected to one end of the fixing post three. The outer wall of the locking block is slidably connected to the inside of the filter screen, and a spring is installed inside the water tank.

[0009] Furthermore, the clamp is disposed inside the housing, one end of the push rod is fixedly connected to the outer wall of the connecting rod three, and two fixing columns one are fixedly connected to the outer wall of the connecting rod three. Connecting column two and connecting column three are respectively fixedly connected to the outer walls of the two fixing columns one, and the ends of connecting column two and connecting column three are fixedly connected to the outer wall of connecting column one.

[0010] Furthermore, one end of the spring is fixedly connected to the inner wall of the water tank, and the other end of the spring is fixedly connected to the outer wall of the locking block.

[0011] Furthermore, the bottom of the guide rail is fixedly connected to the upper surface of the base, and the clamp is disposed above the base.

[0012] Furthermore, the cylinder is disposed on one side of the outer wall of the base, and the outer walls of the second and third connecting columns are slidably connected to the inside of the base.

[0013] Furthermore, the water tank is located on one side of the outer wall of the base, and the outer wall of the fixing column is slidably connected to the inside of the water tank.

[0014] Furthermore, the connecting column is provided on both sides of the outer wall of the base, and the outer wall of the base is fixedly connected to the upper surface of the base.

[0015] This utility model has the following beneficial effects:

[0016] In this invention, a cylinder pushes a push rod to move horizontally, causing the connecting rod three to rotate around the rotating shaft three, which causes the connecting column two and the connecting column three to slide in opposite directions. This causes the fixed plate to contract or expand along the guide rail. The fixture, through the rotating shaft one, drives the connecting rod one and the connecting rod two to form a symmetrical linkage mechanism. The slider slides inside the limit block. This invention solves the problem that traditional CNC machining center devices have poor adaptability to liquid forged automotive swing arms due to the complex geometric features of the liquid forged parts, resulting in time-consuming adjustments and limited positioning repeatability. This invention achieves an adaptive clamping effect for liquid forged automotive swing arms.

[0017] In this invention, by starting the water pump, coolant in the water tank is drawn from the water tank through the inlet pipe and delivered to the high-pressure nozzle through the outlet pipe to form a directional high-pressure jet. This jet directly targets the area where the tool and workpiece are in contact, quickly reducing the cutting temperature and flushing away debris. This solves the problem that the high temperature generated during processing can easily cause the tool to overheat, and that high-temperature thermal stress can destroy the dense grain structure of the liquid forging. This invention achieves the effect of rapid cooling of the tool. Attached Figure Description

[0028] Reference Figure 1 - Figure 7 The present invention provides an embodiment of a liquid forging automotive swing arm CNC machining center device, including a base 2, which serves as the basic support structure of the device to ensure the structural stability of the entire device. A housing 1 is fixedly connected to the top of the base 2, and a clamping assembly is provided inside the housing 1.

[0029] The clamping assembly includes a clamp 6, with a rotating shaft 21 fixedly connected inside the clamp 6.

A rotating shaft 22 and a fixed post 29 are fixedly connected to one end of the connecting rod 23 and the connecting rod 24. The clamp 6 achieves adaptive clamping of irregularly shaped swing arm workpieces through the linkage of the internal rotating shaft 21 with the connecting rods 23 and 24. A slider 27 is fixedly connected to the end of the fixed post 29, and a limit block 25 is slidably connected to the outer wall of the slider 27.

A water tank 12 is fixedly connected to one end of the water inlet pipe 11. The water pump 10 draws coolant from the water tank 12 and delivers it to the high-pressure nozzle 8 through the water outlet pipe 9 to cool the contact area between the cutting tool 5 and the workpiece, reduce the cutting temperature, and flush away debris. A filter screen 34 is slidably connected inside the water tank 12. A guide pipe 14 is provided above the water tank 12. One end of the guide pipe 14 is fixedly connected to the outer wall of the base 2. A guide channel 16 is provided inside the base 2. The guide channel 16 and the guide pipe 14 collect wastewater on the processing table to realize the recycling of coolant and save resources.

The locking block 35 is slidably connected to the inside of the filter screen 34. A spring 36 is provided inside the water tank 12.

[0030] Reference Figure 1 - Figure 7The clamp 6 is located inside the housing 1. One end of the push rod 33 is fixedly connected to the outer wall of the connecting rod 32. Two fixed posts 28 are fixedly connected to the outer wall of the connecting rod 32. The connecting rod 32 rotates around the pivot 31, converting the linear motion of the push rod 33 into symmetrical reverse sliding, ensuring the symmetry of the clamping action. Connecting posts 20 and 36 are fixedly connected to the outer walls of the two fixed posts 28 respectively. The ends of connecting posts 20 and 36 are fixedly connected to the outer wall of connecting post 17. One end of the spring 36 is fixedly connected to the inner wall of the water tank 12. The other end is fixedly connected to the outer wall of the card block 35. The bottom of the guide rail 19 is fixedly connected to the upper surface of the base 2. The guide rail 19 provides sliding guidance for the fixing plate 7 to ensure that the clamp 6 moves symmetrically and synchronously. The clamp 6 is set above the base 30. The cylinder 18 is set on one side of the outer wall of the base 30. The outer walls of the connecting column 20 and the connecting column 36 are slidably connected to the inside of the base 30. The water tank 12 is set on one side of the outer wall of the base 2. The outer wall of the fixing column 37 is slidably connected to the inside of the water tank 12. The connecting column 17 is set on both sides of the outer wall of the base 30. The outer wall of the base 30 is fixedly connected to the upper surface of the base 2.

[0031] Working principle: First, the workpiece is placed on the upper surface of the base 30. Then, the cylinder 18 is activated, pushing the push rod 33 to move horizontally, causing the connecting rod 32 to rotate around the rotating shaft 31. Then, the power is synchronously transmitted to the connecting rod 20 and the connecting rod 36 through the fixed column 28, causing them to slide in opposite directions along the inside of the base 30. This drives the connecting rod 17 on both sides to move the fixed plate 7 to retract towards the center or expand outward along the guide rail 19. At the same time, the fixture 6 drives the connecting rod 23 and the connecting rod 24 through the rotating shaft 21 to form a symmetrical linkage mechanism, so that the rotating shaft 22 and the slider 27 move synchronously. The slider 27 slides along a specific trajectory under the constraint of the limit block 25, further adjusting the clamping surface posture of the fixture 6, realizing the self-adaptive clamping of the fixture 6 to the irregularly shaped workpiece, forming a multi-directional dynamic clamping force. In addition, when the motor 3 is started to drive the tool 5 to process the workpiece, The water pump 10 draws coolant from the water tank 12 through the inlet pipe 11 and delivers it to the high-pressure nozzle 8 through the outlet pipe 9 to form a directional high-pressure jet. This jet directly targets the contact area between the tool 5 and the workpiece, rapidly reducing the cutting temperature and flushing away debris to prevent thermal deformation and wear of the tool 5. Wastewater flows into the guide channel 16 inside the base 2 along with the processing table and returns to the water tank 12 through the guide pipe 14, forming a closed loop. When the returning liquid passes through the filter screen 34, metal debris and impurities are intercepted on the surface of the filter screen 34. The purified coolant settles at the bottom of the water tank 12 for reuse. To facilitate the maintenance of the filter screen 34, pressing the button 15 causes the fixing column 37 to push the locking block 35 to overcome the elastic force of the spring 36 and disengage from the slot of the filter screen 34. At this time, the filter screen 34 can be quickly pulled out and cleaned along the inner wall of the water tank 12 through the handle 13. After resetting, the spring 36 automatically rebounds, causing the locking block 35 to lock the filter screen 34.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
