Description

Technical Field

[0001] The invention relates to the technical field of header processing, in particular to a multi-component machine tool for fine processing of an air-conditioning header. Background Art

[0002] In the automobile air conditioning system, the high-temperature gas refrigerant discharged from the compressor first enters the condenser for cooling and heat dissipation. In order to improve the heat dissipation effect and reduce the pipe resistance of the pipeline, the condenser is usually designed with multiple shunts for cooling. After flowing through the condenser, these shunt refrigerants will enter a header, namely the automobile air conditioning header, for collection. Subsequently, the collected refrigerant enters the expansion valve, and after being reduced in pressure, it is sent to the evaporator for heat absorption and evaporation, thereby achieving cooling inside the car. The automobile air conditioning header is usually made of metal materials, such as copper, aluminum, etc., to ensure its strength and corrosion resistance.

[0003] The processing technology of manifold is a complex process involving multiple steps. It is usually processed by CNC machine tools and other equipment to ensure the accuracy of the manifold diameter and surface finish. During processing, it usually undergoes processes such as heat treatment, cooling, cutting, drilling and coating.

[0033] When the drill bit 160 moves downward, the moving plate 220 moves toward the standing plate 210 to clamp the manifold.

[0034] See Figure 1 and Figure 2 A slide groove 230 is provided on the processing platform 110, and the moving plate 220 is slidably installed with the slide groove 230. A driving gear 320 and a transmission gear 340 are rotatably installed on the side of the vertical plate 120. The driving gear 320 and the transmission gear 340 are jointly installed with a transmission belt 330. The telescopic end side of the lifting member 140 is connected with a driving tooth plate 310, and the driving tooth plate 310 is meshed with the driving gear 320. A connecting seat 350 is installed on the side of the moving plate 220, and a side of the connecting seat 350 adjacent to the vertical plate 210 is connected with a transmission tooth plate 360, and the transmission tooth plate 360 ​​is meshed with the transmission gear 340. When the driving tooth plate 310 moves downward, the transmission tooth plate 360 ​​moves toward the direction of the standing plate 210 .

[0035] The driving tooth plate 310 is configured as a straight plate with teeth on the side, the teeth of the driving tooth plate 310 are arranged at the bottom, and there are no teeth at the upper end of the driving tooth plate 310. A punching motor 150 is installed at the bottom of the telescopic end of the lifting member 140, and the drill bit 160 is connected to the motor shaft of the punching motor 150.

[0036] See Figure 7 The first centering rod 242 is coaxially mounted at the center of the first sleeve 241, and there is a gap between the first centering rod 242 and the first sleeve 241. The first centering rod 242 is configured as a rod body with a gradually changing diameter, and the diameter of one end of the first centering rod 242 adjacent to the standing plate 210 is larger than that of the other end. See Figure 8 The second centering rod 252 is coaxially installed at the center of the second sleeve 251. There is a distance between the second centering rod 252 and the second sleeve 251.

The second centering rod 252 is set as a truncated cone-shaped rod body, and the maximum diameter of the second centering rod 252 is the same as that of the first centering rod 242.

[0037] In this embodiment: through the cooperation between the lifting member 140 and the drill bit 160, the drill bit 160 can be driven to rotate and controlled to move downward to achieve the drilling of the collector. Through the setting of the first clamping assembly 240, when loading, it is only necessary to manually plug one end of the collector with the first clamping assembly 240, and then through the transmission cooperation of the driving tooth plate 310, the driving gear 320, the transmission gear 340 and the transmission tooth plate 360, during the operation of the lifting member 140, the driving tooth plate 310 moves downward to drive the driving gear 320 to rotate, so that the transmission tooth plate 360 ​​moves horizontally, so that when the drill bit 160 moves downward, the second clamping assembly 250 moves toward the standing plate 210 at the same time, and completes the clamping of the collector before drilling, so that the manual support can be released, and automatic clamping is achieved, ensuring the stability of the collector during drilling and improving the processing efficiency. In addition, by setting the first centering rod 242 and the second centering rod 252 to have a gradual diameter change, the docking of the two ends of the collecting pipe is facilitated. After clamping, the two ends of the collecting pipe are confined in the gap between the first centering rod 242 and the first sleeve 241 and the gap between the second sleeve 251 and the second centering rod 252, so that the collecting pipe is coaxial with the first clamping assembly 240 and the second clamping assembly 250, and the collecting pipe is punched in a horizontal state as much as possible, thereby improving the processing effect of the automobile air-conditioning collecting pipe.

[0038] Embodiment 2: This embodiment is intended to promote the solution of the problem that in order to facilitate the docking of the two clamping seats with the ends of the manifold, the first centering rod 242 and the second centering rod 252 are set to rods with varying diameters. When manually loading the material at the beginning, one end of the manifold is first plugged into the first clamping assembly 240, which may cause an inaccurate angle and the manifold is not horizontal. After the second clamping assembly 250 is close to clamp, the angle may not be able to return to the correct position. This embodiment is an improvement made on the basis of Embodiment 1, which improves the machine tool's ability to accurately clamp pipe fittings. For details, please refer to Figure 1-Figure 10An airbag ring 410 is installed on the first clamping component 240, a reciprocating component 420 is installed at one end of the transmission gear plate 360 ​​adjacent to the vertical plate 210, a first piston plate 430 is installed at the end of the reciprocating component 420, a pneumatic cavity 440 is opened in the vertical plate 120, the reciprocating component 420 is plugged into the pneumatic cavity 440, and the first piston plate 430 is slidably fitted with the inner wall of the pneumatic cavity 440, an end of the pneumatic cavity 440 away from the connecting seat 350 is connected to an air guide tube 450, and the other end of the air guide tube 450 is connected to the airbag ring 410.

[0039] The airbag ring 410 is configured as a rubber airbag with folds. A groove is provided at one end of the first centering rod 242 with a smaller diameter, and the airbag ring 410 is installed in the groove.

[0040] The reciprocating assembly 420 includes a fixed cylinder 421 connected to the connecting seat 350 , a moving rod 422 is inserted into the fixed cylinder 421 , a first piston plate 430 is installed at the end of the moving rod 422 , and a return spring 423 is installed between the moving rod 422 and the fixed cylinder 421 .

[0041] See Fig.10 The reciprocating assembly 420 is set as a combination of a fixed cylinder 421, a moving rod 422 and a return spring 423, so that the transmission gear plate 360 ​​can continue to move after the first piston plate 430 touches the top, thereby inflating the airbag ring 410 in advance, aligning the collecting pipe, and then clamping and stabilizing the collecting pipe.

[0042] See Figure 5 and Figure 6 The diameter of the airbag ring 410 after expansion is the same as the maximum diameter of the first centering rod 242.

[0043] In this embodiment: by installing the airbag ring 410 on the first centering rod 242, and setting the reciprocating assembly 420 and the first piston plate 430, when the moving plate 220 approaches the standing plate 210, the first piston plate 430 slides in the pneumatic chamber 440, so that the gas between the first piston plate 430 and the pneumatic chamber 440 is pushed into the air guide tube 450, causing the airbag ring 410 to expand. The diameter of the expanded airbag ring 410 is the same as the maximum diameter of the first centering rod 242. The maximum diameter of the first centering rod 242 is located at the end, and a straight line is determined with the two points of the expanded airbag ring 410, and the diameters are the same, so the formed straight line is horizontal. In this way, the placement angle of the collecting pipe can be adjusted before it contacts the second clamping assembly 250, further ensuring that the collecting pipe is in a horizontal state, ensuring the accuracy of the punching angle, and further improving the processing accuracy of the collecting pipe.

[0044] Embodiment 3: This embodiment is intended to solve the problem that after drilling, when the drill bit 160 moves upward, part of the powder generated by drilling will fall into the manifold, and the powder in the pipe is inconvenient to clean. This embodiment is an improvement made on the basis of embodiment 2, and realizes the function of cleaning the pipe by the machine tool. For details, please refer to Figure 1-Figure 10 A connecting rod 550 is connected to the side of the connecting seat 350, and a piston rod 560 is connected to the end of the connecting rod 550. The piston rod 560 is parallel to the transmission gear plate 360, and a second piston plate 561 is installed at the end of the piston rod 560. An air suction chamber 570 is opened in the vertical plate 120, and the piston rod 560 is plugged into the air suction chamber 570. The second piston plate 561 slides and fits with the inner wall of the air suction chamber 570. The end of the air suction chamber 570 away from the connecting rod 550 is connected to the ventilation pipe 540, and the second centering rod 252 is coaxially opened with an air suction channel 530. The other end of the ventilation pipe 540 is connected to the air suction channel 530, which is used to suck the powder generated by drilling inside the collecting pipe.

[0045] A collecting box 260 is installed on the back side of the moving plate 220, a placement plate 261 is installed inside the collecting box 260, the end of the ventilation pipe 540 is installed on the placement plate 261, a filter screen 590 is installed at the pipe mouth of the ventilation pipe 540 adjacent to the placement plate 261, a flared enclosure plate 262 is installed between the air intake duct 530 and the placement plate 261, a first one-way valve 263 is installed at the pipe mouth of the air intake duct 530 adjacent to the placement plate 261, and a second one-way valve 264 is arranged on the bottom side of the flared enclosure plate 262.

[0046] An air blowing channel 510 is opened at the center of the first centering rod 242, and the air blowing channel 510 is connected to an air blowing pipe 520. The other end of the air blowing pipe 520 is connected to the pneumatic cavity 440, and the pipe opening of the air blowing pipe 520 is arranged at the end of the pneumatic cavity 440 away from the air guide pipe 450.

[0047] A third one-way valve 580 is installed at the end of the pneumatic cavity 440 adjacent to the blowing pipe 520. When the moving plate 220 moves away from the standing plate 210, the gas on the side of the first piston plate 430 adjacent to the blowing pipe 520 is compressed into the blowing channel 510 and blown out.

[0048] In this embodiment: through the setting of the suction channel 530, and the cooperation between the piston rod 560 and the suction chamber 570, during the resetting process of the moving plate 220 after the drilling is completed, the second piston plate 561 slides synchronously, so that a negative pressure is generated between the second piston plate 561 and the ventilation pipe 540, so that the suction channel 530 has a suction effect, which can suck away the powder in the manifold, realize the cleaning of the manifold by the machine tool, improve the processing effect, and reduce the cost and steps of subsequent cleaning; Moreover, by configuring the collecting box 260, the placement plate 261, the expansion enclosure plate 262, the first one-way valve 263 and the second one-way valve 264, when the moving plate 220 moves away, the first one-way valve 263 opens, the second one-way valve 264 closes, and the powder sucked by the suction channel 530 is collected in the expansion enclosure plate 262. When the moving plate 220 approaches, the first one-way valve 263 closes, and the air pressure in the second one-way valve 264 increases, so that the second one-way valve 264 opens and blows the powder collected in the expansion enclosure plate 262 into the collecting box 260, effectively utilizing the air pressure effect brought by the movement of the second piston plate 561, and further improving the effect of collecting powder. Furthermore, by providing the blowing hole 510 and the blowing pipe 520, during the resetting process of the shift plate 220, the gas between the first piston plate 430 and the blowing pipe 520 will be compressed into the blowing pipe 520, thereby improving the utilization rate of the first piston plate 430 and making it move in different directions at different times to produce different effects. At this time, the blowing hole 510 produces a blowing effect, blowing the powder in the collecting pipe toward the direction of the suction hole 530, thereby further improving the effect of cleaning and collecting the powder in the collecting pipe.
