Description

Technical Field

[0001] This utility model relates to the field of cylinder block processing technology, specifically a coaxial positioning device for the cylinder block of an automotive air conditioning compressor. Background Technology

[0002] The automotive air conditioning compressor is the heart of the automotive air conditioning refrigeration system, playing the role of compressing and transporting refrigerant vapor. The compressor has a cylinder block, which needs to be polished by a grinding device during the manufacturing process to give it a better surface roughness.

[0003] In the prior art, patent announcement number CN219684942U discloses a grinding device for the cylinder block of an automotive air conditioning compressor, including a grinding assembly and a positioning device. The grinding assembly is disposed above the positioning device, and there are multiple sets of grinding assemblies arranged at intervals. The positioning device includes a positioning assembly and a driving component. The driving component is connected to multiple sets of positioning assemblies. The positioning assembly includes a rotating part, a guide part, and a positioning block. The driving component is connected to the rotating part and drives the rotating part to rotate. The rotating part has an arc-shaped hole and a through hole, and multiple arc-shaped holes are arranged around the through hole. The guide part is disposed above the rotating part and has a guide hole. The guide hole is positioned corresponding to the arc-shaped hole, and multiple guide holes are arranged radially from the center of the guide part. The positioning block has a mounting post, which passes through the guide hole and is disposed in the arc-shaped hole.

[0004] The aforementioned device positions the compressor cylinder using a positioning component. After the cylinder grinding is completed, workers must unload the material. Furthermore, during the grinding process, some debris inevitably falls into the cylinder's interior. If this debris is not cleaned promptly, it will not only affect the cylinder's surface quality but may also interfere with subsequent processing steps. Therefore, workers also need to thoroughly clean the inside of the cylinder. These additional steps undoubtedly consume time, thus impacting the overall processing speed. Utility Model Content

[0005] The purpose of this invention is to provide a coaxial positioning device for the cylinder block of an automotive air conditioning compressor to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coaxial positioning device for an automotive air conditioning compressor cylinder, comprising a servo motor, a positioning base fixedly mounted at the output end of the servo motor, a resistance rod fixedly mounted on the positioning base, a positioning slot provided on the positioning base, and a unloading mechanism mounted on the positioning base. The unloading mechanism includes a rotating plate rotatably mounted on the side wall of the positioning base, a positioning column fixedly mounted on the rotating plate, a base fixedly mounted on the positioning column, a first sleeve fixedly mounted at the bottom of the base, a first lead screw rotatably mounted inside the first sleeve, a first nut threaded onto the first lead screw, a first telescopic rod slidably mounted up and down inside the first sleeve, and the first nut fixedly mounted on the first telescopic rod. A purging mechanism is mounted on one side of the base.

[0007] Preferably, the unloading mechanism further includes a drive motor fixedly installed on one side of the base, a drive shaft fixedly installed at the output end of the drive motor, and helical gears fixedly installed on both the drive shaft and the first lead screw, with the two sets of helical gears meshing together.

[0008] Preferably, a coupling is installed at the output end of the drive motor, and the drive shaft is connected to the output end of the drive motor through the coupling.

[0009] Preferably, the positioning base is provided with a frame on its outer side, and the positioning base is rotatably mounted on the frame and the servo motor is fixedly mounted on one side of the frame.

[0010] Preferably, the purging mechanism includes a second sleeve fixedly installed on one side of the base, a second lead screw rotatably installed inside the second sleeve, and the end of the drive shaft fixedly installed on the second lead screw. A second nut is threaded onto the second lead screw. A second telescopic rod is slidably installed left and right inside the second sleeve. A coupling port is fixedly installed at the end of the second telescopic rod. A flexible corrugated pipe is connected to the coupling port, and an air inlet pipe is connected to the flexible corrugated pipe.

[0011] Preferably, the second lead screw is provided with a coupling, and the end of the drive shaft is connected to the second lead screw through the coupling.

[0012] Preferably, the second telescopic rod is slidably installed inside the second sleeve via the second nut, and the mating interface is movably installed inside the positioning base via the second telescopic rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, after the drive motor starts, the power it generates is transmitted to the drive shaft, which then rotates and drives the second lead screw to rotate. The rotational motion of the second lead screw is further converted into the linear motion of the second nut, causing it to move forward. The forward movement of the second nut causes the second telescopic rod to extend, thereby pushing the interface forward until it contacts the hole at the bottom of the positioning slot. Once the interface contacts the hole at the bottom of the positioning slot, gas is injected into the flexible bellows through the air inlet pipe. After entering the flexible bellows, the gas is discharged from the cylinder at high speed. This process effectively removes impurities from the cylinder, achieving rapid cleaning of the cylinder.

[0015] When the cylinder opening is facing downwards, the drive shaft can drive the first lead screw to rotate. Subsequently, the rotation of the first lead screw will cause the first nut to move forward, thereby pushing the first telescopic rod to extend. The extension of the first telescopic rod will cause the cylinder to disengage from the positioning slot, thus realizing the automatic unloading process of the cylinder. Attached Figure Description

[0021] 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.

[0022] like Figure 1and Figure 2 As shown, this utility model provides a technical solution for a coaxial positioning device for the cylinder of an automotive air conditioning compressor, including a servo motor 2, a positioning base 1 fixedly installed at the output end of the servo motor 2, a resistance rod 3 fixedly installed on the positioning base 1, a positioning slot 4 opened on the positioning base 1, a unloading mechanism 5 installed on the positioning base 1, and a blowing mechanism 6 installed on one side of the base 503. Through the cooperation of the unloading mechanism 5 and the blowing mechanism 6, the cylinder can be cleaned, and after the cylinder is cleaned, it will automatically detach from the positioning base 1 to realize automatic unloading of the cylinder.

[0023] like Figure 2 and Figure 3 As shown, the unloading mechanism 5 includes a rotating plate 501 rotatably mounted on the side wall of the positioning base 1, a positioning column 502 fixedly mounted on the rotating plate 501, a base 503 fixedly mounted on the positioning column 502, a first sleeve 509 fixedly mounted at the bottom of the base 503, a first lead screw 507 rotatably mounted inside the first sleeve 509, a first nut 508 threaded onto the first lead screw 507, a first telescopic rod 510 slidably mounted up and down inside the first sleeve 509, and the first nut 508 fixedly mounted on the first telescopic rod 510. The unloading mechanism 5 also includes a drive motor 506 fixedly mounted on one side of the base 503, a drive shaft 505 fixedly mounted at the output end of the drive motor 506, and helical gears 504 fixedly mounted on both the drive shaft 505 and the first lead screw 507, with the two sets of helical gears 504 meshing together.

[0024] Specifically, when the cylinder opening is placed downwards, the drive shaft 505 can effectively drive the first lead screw 507 to rotate. As the first lead screw 507 rotates, it further causes the first nut 508 to move forward along the direction of the lead screw. During the forward movement of the first nut 508, it applies a force to the first telescopic rod 510, allowing the telescopic rod to extend forward. When the first telescopic rod 510 extends forward, it applies a thrust to the cylinder, thereby pushing the cylinder out of the positioning slot 4. Through this series of mechanical actions, the automatic unloading process of the cylinder is realized.

[0025] like Figure 2 and Figure 4As shown, the purging mechanism 6 includes a second sleeve 604 fixedly installed on one side of the base 503. A second lead screw 605 is rotatably installed inside the second sleeve 604, and the end of the drive shaft 505 is fixedly installed on the second lead screw 605. A second nut 606 is threaded onto the second lead screw 605. A second telescopic rod 603 is slidably installed left and right inside the second sleeve 604. A coupling 601 is fixedly installed at the end of the second telescopic rod 603. A flexible bellows 602 is connected to the coupling 601. An air inlet pipe 607 is connected to the flexible bellows 602. A coupling is provided on the second lead screw 605, and the end of the drive shaft 505 is connected to the second lead screw 605 through the coupling.

[0026] Specifically, when the drive motor 506 is started, it will drive the drive shaft 505 to rotate. As the drive shaft 505 rotates, the second lead screw 605 also rotates. The rotation of the second lead screw 605 causes the second nut 606 to move forward. During this forward movement, the second nut 606 pushes the second telescopic rod 603 to extend forward. The extension of the second telescopic rod 603 causes the interface 601 to move forward until it abuts against the hole at the bottom of the positioning slot 4. Once the interface 601 abuts against the hole at the bottom of the positioning slot 4, compressed air can be introduced into the flexible bellows 602 through the air inlet pipe 607. After entering the flexible bellows 602, the compressed air is discharged at high speed through the cylinder body. This process effectively removes impurities from the cylinder body, thus achieving rapid cleaning of the cylinder body.

[0027] Working principle: During use, the cylinder body is first placed in the positioning slot 4. A certain resistance exists between the resistance rod 3 and the cylinder body, thus confining the cylinder body within the positioning slot 4. After the cylinder body is confined in the positioning slot 4, the servo motor 2 drives the positioning base 1 to rotate, causing the cylinder body opening to face upwards. Once the cylinder body opening is facing upwards, a grinding device can be used to grind the cylinder body. After grinding, the servo motor 2 drives the positioning base 1 to rotate 90°, causing the cylinder body opening to face one side. Once the cylinder body opening is facing one side, the drive motor 506 can be started. Starting the drive motor 506 will drive the drive shaft 505 to rotate, driving... After shaft 505 rotates, it will drive the second lead screw 605 to rotate. After the second lead screw 605 rotates, it will drive the second nut 606 to move forward. After the second nut 606 moves forward, it will cause the second telescopic rod 603 to extend. When the second telescopic rod 603 extends, it will drive the interface 601 to move forward and abut against the hole at the bottom of the positioning slot 4. After the interface 601 abuts against the hole at the bottom of the positioning slot 4, it can send air into the flexible bellows 602 through the air inlet pipe 607. The gas entering the flexible bellows 602 will eventually be discharged at high speed through the cylinder, thereby taking away impurities in the cylinder and quickly cleaning the cylinder. After cleaning is completed, the positioning base 1 can be rotated again so that the cylinder opening faces downward. When the cylinder opening faces downward, the drive shaft 505 can drive the first lead screw 507 to rotate. After the first lead screw 507 rotates, it will drive the first nut 508 to move forward. After the first nut 508 moves forward, it will drive the first telescopic rod 510 to extend. When the first telescopic rod 510 extends, it will push the cylinder to disengage from the positioning slot 4, thereby realizing automatic unloading of the cylinder.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
