Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic deburring equipment, specifically to an ultrasonic deburring device for valve islands in the thermal management system of new energy vehicles. Background Technology

[0002] As a core fluid control component, the valve island in the thermal management system of new energy vehicles integrates multiple precision valve holes, flow channels, and sealing surfaces. Its machining accuracy directly affects the heat exchange efficiency and operational stability of the thermal management system. During the valve island production process, tiny burrs and oil stains can easily remain on the inner wall of the valve holes, at the junctions of the flow channels, and in the assembly gaps of components. If these impurities are not thoroughly removed, they can lead to valve stem jamming, sealing failure, and even safety hazards such as system leakage. Therefore, deburring is a critical process in valve island manufacturing.

[0003] Currently, ultrasonic cleaning technology is widely used in the industry for deburring. The cavitation effect generated by ultrasonic vibration impacts the surface of the workpiece, achieving the removal of burrs and impurities. However, in traditional ultrasonic cleaning devices, valve island workpieces are usually placed statically in the cleaning frame. Due to the influence of ultrasonic field distribution characteristics, blind holes, deep cavities and gaps on the surface of the workpiece are prone to forming cleaning dead zones. In the static state, the adhesion between burrs and the workpiece surface is difficult to be effectively broken, resulting in some tiny burrs not being completely removed. Residual impurities will still affect the assembly accuracy and service life of the valve island. Therefore, we need to provide an ultrasonic deburring device for valve islands in the thermal management system of new energy vehicles. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic deburring device for valve islands in a thermal management system for new energy vehicles. In traditional static cleaning, blind holes, deep cavities, and flow channel gaps in valve islands are prone to forming cleaning blind spots due to uneven ultrasonic field coverage. The shaking state can drive the workpiece and the cleaning fluid to move relative to each other, allowing the cavitation effect to be precisely applied to the burr attachment point, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic deburring device for valve islands in a new energy vehicle thermal management system, comprising:

[0006] An ultrasonic cleaner, comprising an ultrasonic chamber and a placement frame disposed within the ultrasonic chamber.

[0007] The sliding component includes slide rails fixed on both sides of the ultrasonic chamber, and slide tracks are fixedly installed on both sides of the inner wall of the ultrasonic cleaning chamber. The slide rails are slidably installed on the top of the slide tracks.

[0008] A drive mechanism is installed on one side of the ultrasonic chamber and is used to drive the ultrasonic chamber to swing within the ultrasonic cleaning frame.

[0009] Preferably, a pusher seat is fixedly installed on the top of the slide rail, and the pusher seat is used in conjunction with the drive mechanism.

[0010] Preferably, the drive mechanism is detachably connected to the ultrasonic frame via bolts.

[0011] Preferably, the drive structure includes a bracket fixed to the surface of the ultrasonic chamber by bolts, a motor is fixedly installed on the top of the bracket, a disk is fixedly installed at the output end of the motor, a push rod is fixedly installed on one side of the disk, and a groove for the push rod to move is provided on one side of the push seat.

[0012] Preferably, the slide rail includes a frame fixed to the inner wall of the ultrasonic chamber, a plurality of rollers are rotatably mounted inside the frame, and a rectangular groove adapted to the rollers is provided at the bottom of the slide rail.

[0013] Preferably, the bottom and side walls of the placement frame are both embedded with filter screens.

[0014] Preferably, the ultrasonic chamber is provided with a drain valve pipe on one side.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In traditional static cleaning, blind holes, deep cavities, and flow channel gaps in the valve island of this utility model are prone to forming cleaning blind spots due to uneven coverage of the ultrasonic field. The shaking state can drive the workpiece and the cleaning fluid to move relative to each other, allowing the cavitation effect to act precisely on the burr attachment points, effectively removing tiny residual burrs. The reciprocating shaking of the placement frame can accelerate the flow of the cleaning fluid, promptly removing the detached burrs and oil stains, preventing impurities from re-attaching to the workpiece surface, while enhancing the transmission effect of ultrasonic vibration and shortening the cleaning cycle.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an ultrasonic deburring device for valve islands in a thermal management system of a new energy vehicle, comprising:

[0024] An ultrasonic cleaner 100 includes an ultrasonic chamber 110 and a placement frame 120 disposed inside the ultrasonic chamber 110.

[0025] The sliding component 200 includes slide rails 210 fixed on both sides of the ultrasonic box 110, and slide tracks 220 are fixedly installed on both sides of the inner wall of the ultrasonic cleaning box. The slide rails 210 are slidably installed on the top of the slide tracks 220.

[0026] Drive mechanism 300 is installed on one side of ultrasonic box 110 and is used to drive ultrasonic box 110 to swing within ultrasonic cleaning frame.

[0027] Specifically, in traditional static cleaning, blind holes, deep cavities, and flow channel gaps in valve islands are prone to forming cleaning blind spots due to uneven ultrasonic field coverage. The shaking motion allows the workpiece and cleaning fluid to move relative to each other, enabling the cavitation effect to precisely target the burr attachment points and effectively remove tiny residual burrs. The 120° reciprocating shaking of the placement frame accelerates the flow of the cleaning fluid, promptly removing the detached burrs and oil stains, preventing impurities from re-attaching to the workpiece surface, while also enhancing the transmission effect of ultrasonic vibration and shortening the cleaning cycle.

[0028] A pusher seat 4 is fixedly installed on the top of the slide rail 210, and the pusher seat 4 is used in conjunction with the drive mechanism 300.

[0029] Specifically, the side of the push seat 4 away from the groove is welded and fixed to the side wall of the placement frame 120. The groove is an arc-shaped groove, and the inner wall of the arc-shaped groove is covered with a polytetrafluoroethylene wear-resistant layer. The width of the arc-shaped groove is in clearance fit with the diameter of the push rod 340. The clearance fit between the arc-shaped groove and the push rod 340 and the wear-resistant layer reduce motion friction loss and improve transmission stability.

[0030] The drive mechanism 300 is detachably connected to the ultrasonic frame via bolts.

[0031] Furthermore, the support 310 of the drive mechanism 300 is an L-shaped stainless steel support 310. The vertical section of the support 310 is detachably connected to the threaded holes on the surface of the ultrasonic box 110 by at least two high-strength bolts. The top of the horizontal section of the support 310 is provided with a mounting base for fixing the motor 320. The mounting base and the base of the motor 320 are locked together by bolts. The surface of the bolt thread is coated with an anti-rust coating, and an elastic washer is provided between the bolt and the connection hole of the support 310.

[0032] The drive structure includes a bracket 310 fixed to the surface of the ultrasonic box 110 by bolts, a motor 320 fixedly mounted on the top of the bracket 310, a disc 330 fixedly mounted on the output end of the motor 320, a push rod 340 fixedly mounted on one side of the disc 330, and a groove for the push rod 340 to move on one side of the push seat 4.

[0033] It is worth noting that motor 320 is a stepper motor 320, and the output shaft of motor 320 is interference-fitted with the center hole of disk 330 via a flat key; push rod 340 is a cylindrical alloy steel part, one end of push rod 340 is fixedly connected to the edge of disk 330 by welding, and the other end of push rod 340 is a hemispherical structure with a polished surface. Stepper motor 320 can precisely control speed, and the interference fit with flat key ensures stable power transmission; the hemispherical structure and polished surface of push rod 340 reduce contact friction with the arc groove and improve transmission efficiency.

[0034] The slide rail 220 includes a frame 221 fixed to the inner wall of the ultrasonic box 110. Multiple rollers 222 are rotatably installed inside the frame 221. A rectangular groove 223 adapted to the rollers 222 is opened at the bottom of the slide rail 210.

[0035] It should be noted that the frame 221 is a one-piece aluminum alloy structure. At least four rollers 222 are evenly distributed along the length of the frame 221. The rollers 222 are made of nylon. The two ends of the central axis of the rollers 222 are rotatably connected to the side wall of the frame 221. The aluminum alloy frame 221 is lightweight and strong. The nylon rollers 222 have both wear resistance and cushioning performance, reducing noise and wear when the slide rail 210 moves.

[0036] The bottom and side walls of the placement frame 120 are both embedded with filter screens 5;

[0037] The filter section 5 is made of 304 stainless steel with a mesh size of 80-120. The filter is detachably connected to the frame of the placement frame 120 by a snap fastener. An elastic buffer pad is provided between the inner wall of the placement frame 120 and the filter. The edge of the filter is edged with rubber. The 304 stainless steel filter combines corrosion resistance and filtration accuracy. The 80-120 mesh size can effectively intercept burrs.

[0038] The ultrasonic box 110 is equipped with a drain valve pipe 6 on one side;

[0039] Specifically, the drain valve pipe 6 is made of stainless steel. The drain valve pipe 6 is detachably connected to the side wall of the ultrasonic box 110 via a flange. The drain valve pipe 6 is equipped with a ball valve, and the valve stem of the ball valve extends to the outside of the ultrasonic box 110. The outlet end of the drain valve pipe 6 is equipped with a splash guard.

[0040] This device places the valve island of the new energy vehicle thermal management system inside the placement frame 120. At the same time, the slide rails 210 on both sides of the placement frame 120 are located on the top of the two slides 220 respectively. The bracket 310 is fixed to one side of the ultrasonic box 110 with bolts. At the same time, the push rod 340 is inserted into the groove on one side of the push seat 4. At this time, the motor 320 is started to drive the disc 330 to rotate. The push rod 340 on one side of the disc 330 slides in the groove of the push seat 4, realizing the horizontal swing of the push seat 4, which in turn drives the entire placement frame 120 to reciprocate and shake. The rectangular groove 223 at the bottom of the slide rail 210 is located in the roller 222 at the top of the frame 221, driving multiple rollers 222 to rotate. When disassembling, the drive mechanism 300 is removed, and the entire placement frame 120 can be lifted.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
