Description

Technical Field

[0001] This application relates to the field of quick-connect coupling manufacturing, and in particular to a quick-connect coupling ball mounting device. Background Technology

[0002] A quick-connect coupling is a device for quickly connecting and disconnecting pipes or equipment. It is commonly used in hydraulic and pneumatic systems to allow for the rapid disconnection and connection of pipes when equipment needs to be replaced or repaired.

[0003] The female end of the quick-connect coupling needs to be inlaid with a number of steel balls, and the steel balls are limited in the steel ball hole of the female coupling by the telescopic sleeve. The steel balls are embedded in the mounting block. Before the telescopic sleeve is installed, they are easy to roll out of the steel ball hole. Therefore, the existing steel balls are coated with grease during installation. The grease will stick the steel balls to the steel ball hole and reduce the probability of the steel balls falling out of the steel ball hole before the telescopic sleeve is installed. However, the application of grease will affect the cleanliness of the quick-connect coupling. Summary of the Invention

[0004] To improve the cleanliness of quick-connect couplings, this application provides a quick-connect coupling steel ball installation device.

[0005] The quick-connect coupling ball bearing installation device provided in this application adopts the following technical solution: A quick-connect coupling ball mounting device includes a body, an mounting platform on the body, an mounting ring groove on the mounting platform for placing a female connector, an air extraction pipe on the body, an air extraction channel between the body and the mounting platform, an air extraction port at the center of the mounting ring groove on the mounting platform, and a pressure block on the body for pressing down the end of the female connector away from the mounting platform.

[0006] By adopting the above technical solution, the female connector is installed on the mounting platform and pressed by the pressure block to form a cavity inside the female connector. By connecting an air extraction device to the air extraction pipe to extract air from the cavity inside the female connector, when the steel ball is installed in the steel ball hole of the female connector, the suction of the air extraction device will adsorb the steel ball into the steel ball hole of the female connector, reducing the probability of the steel ball rolling off. There is no need to apply grease to the steel ball so that the steel ball can adhere through grease, which reduces the probability of grease contamination of the quick-connect connector and improves the cleanliness of the quick-connect connector.

[0007] Optionally, the machine body is provided with an installation mechanism, which includes a hopper, a feeding pipe and a feeding nozzle. The hopper is located on the top of the machine body, the feeding pipe is connected to and communicates with the hopper, and the feeding nozzle is installed at the end of the feeding pipe away from the hopper. One end of the feeding nozzle outlet faces the mounting platform, and the mounting platform rotates on the machine body.

[0008] By adopting the above technical solution, the hopper is used to store steel balls, and then the steel balls are fed into the steel ball hole of the female connector through the feeding pipe and feeding nozzle. The rotation of the mounting platform can transport steel balls to all mounting holes around the mounting platform.

[0009] Optionally, the machine body is provided with a drive mechanism, which drives the feeding nozzle to slide toward or away from the mounting platform.

[0010] By adopting the above technical solution, when feeding is required, the feeding nozzle is driven close to the female connector by the drive mechanism, which can reduce the probability of steel balls leaking out during installation. By driving the feeding nozzle away from the female connector by the drive mechanism, the impact of the feeding nozzle on the subsequent installation of the telescopic sleeve can be reduced after the steel balls are installed.

[0011] Optionally, the machine body is provided with a stamping mechanism, which includes a power component and a stamping head. The power component is installed directly above the mounting platform, and the stamping head is installed on the power component. The power component drives the stamping head to slide toward or away from the mounting platform.

[0012] By adopting the above technical solution, the stamping mechanism can easily install the retaining ring on the female connector, thereby restricting the telescopic sleeve and reducing the probability of the telescopic sleeve coming off.

[0013] Optionally, a truncated cone is fixed at one end of the pressure block, and when the pressure block is pressed onto the female connector, the side with the truncated cone faces the power component.

[0014] By adopting the above technical solution, the truncated cone can guide the expansion of the retaining ring, facilitating the installation of the retaining ring.

[0015] Optionally, the stamping head includes a mounting head and a plurality of stamping plates. The mounting head is fixed on the power component, and the stamping plates are slidably disposed on the mounting head. The plurality of stamping plates slide toward or away from the center of the mounting head.

[0016] By adopting the above technical solution, the stamping sheet can slide and abut against the truncated cone when it is stamped against the retaining ring, thereby improving the stamping effect in conjunction with the truncated cone.

[0017] Optionally, a turntable is rotatably mounted on the machine body, and there are two mounting platforms evenly distributed on the turntable. The mounting mechanism and the stamping mechanism are each configured to correspond to one mounting platform. By adopting the above technical solution, the turntable, together with two mounting platforms, achieves a dual-station setup, enabling the installation of ball bearings and telescopic sleeves to be carried out simultaneously at different stations, thereby improving production efficiency.

[0018] Optionally, a material receiving hopper is provided on the outside of the mounting platform.

[0019] By adopting the above technical solution, the receiving hopper can accept falling steel balls, reducing the probability of falling steel balls rolling around and affecting the factory environment, thus causing safety accidents.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By installing the female connector on the mounting platform and pressing it with a pressure block, a cavity is formed inside the female connector. By connecting an air extraction device to the air extraction pipe, the internal cavity of the female connector is evacuated. When the steel ball is installed in the steel ball hole of the female connector, the suction of the air extraction device will adsorb the steel ball into the steel ball hole of the female connector, reducing the probability of the steel ball rolling off. There is no need to apply grease to the steel ball so that the steel ball can adhere to the grease, which reduces the probability of grease contamination of the quick-connect connector and improves the cleanliness of the quick-connect connector. 2. The hopper is used to store steel balls, which are then fed into the steel ball holes of the female connector through the feeding pipe and feeding nozzle. The rotation of the mounting platform can transport steel balls to all mounting holes around the mounting platform. 3. When feeding is required, the feeding nozzle is driven close to the female connector by the drive mechanism, which can reduce the probability of steel balls leaking out during installation. The feeding nozzle is driven away from the female connector by the drive mechanism, which can reduce the impact of the feeding nozzle on the subsequent installation of the telescopic sleeve after the steel balls are installed. 4. The stamping mechanism allows for easy installation of the retaining ring on the female connector, thereby restricting the telescopic sleeve and reducing the probability of it coming off. 5. The turntable, together with two mounting tables, enables a dual-station setup, allowing the installation of ball bearings and telescopic sleeves to be performed simultaneously at different stations, thus improving production efficiency. 6. The receiving hopper is designed to accept falling steel balls, reducing the probability of these balls rolling around and causing safety accidents in the factory environment.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] Quick couplings include male and female couplings (refer to...). Figure 1 The female connector 0 includes a cylindrical body 01. The cylindrical body 01 has several steel ball holes 02 evenly distributed around its length. Steel balls 03 are embedded in the steel ball holes 02. After the steel balls 03 are covered by a spring 04 and a telescopic sleeve 05, the telescopic sleeve 05 is restricted and installed on the cylindrical body 01 by a retaining ring 06. When the male connector needs to be inserted into the female connector 0, the telescopic sleeve 05 is slid first. The telescopic sleeve 05 compresses the spring 04, allowing the steel balls 03 to slide slightly within the steel ball holes 02. At this time, the male connector is inserted into the female connector 0. Then, the telescopic sleeve 05 is released, allowing the telescopic sleeve 05 to return to its original position under the elastic force of the spring 04. The telescopic sleeve 05 abuts against the steel balls 03, causing the steel balls 03 to clamp the male connector.

[0029] This application discloses a quick-connect coupling ball bearing installation device, referring to... Figure 1The system includes a body 1, which comprises a rectangular platform 101 and a frame 102 mounted on the platform 101. A rotary motor 2 is installed inside the platform 101, and a turntable 3 is fixed to the rotary motor 2. The rotary motor 2 drives the turntable 3 to rotate on the platform 101. Two mounting platforms 4 are evenly arranged on the turntable 3 away from the platform 101. A mounting motor 5 is fixed to the side of the turntable 3 facing the platform 101 corresponding to the mounting platform 4. The mounting motor 5 drives the mounting platform 4 to rotate on the turntable 3. A motor annular groove 6 is installed on the platform 101 corresponding to the mounting motor 5, accommodating the mounting motor 5 when the turntable 3 rotates. A mounting annular groove 20 is formed at the end of the mounting platform 4 away from the turntable 3, for placing... The female connector 0 has a cylindrical body 01 and a platform 101 with an air extraction pipe 7 installed on one side. An air extraction channel 8 is provided between the platform 101 and the mounting platform 4. The mounting platform 4 has an air extraction port 9 at the center of the mounting ring groove 20. The air extraction pipe 7 is used to connect to an air extraction device to extract air from the inside of the cylindrical body 01 installed on the mounting platform 4, thereby adsorbing the steel ball 03 onto the cylindrical body 01 and reducing the probability of the steel ball 03 falling off. Two pressure blocks 15 are placed on the platform 101 corresponding to the mounting platform 4. The pressure blocks 15 are used to press the end of the female connector 0 away from the mounting platform 4. A receiving hopper 10 is sleeved on the outside of the mounting platform 4. The receiving hopper 10 is fixed to the mounting platform 4 by bolts and is used to catch the steel ball 03 that is accidentally dropped.

[0030] Reference Figure 1 Since the turntable 3 rotates on the platform 101 and the mounting platform 4 rotates on the turntable 3, in order to ensure that air can still be drawn while the turntable 3 and the mounting platform 4 are rotating, the air extraction channel 8 includes an inlet channel 81, a first annular channel 82, a turntable 3 channel, a second annular channel 84, and an outlet channel 85. The inlet channel 81 is located on the platform 101 and is connected to the air extraction pipe 7. The first annular channel 82 is located on the platform 101 and is a circular channel. The first annular channel 82 passes through the platform 101, abuts against one side of the turntable 3, and is sealed by the turntable 3. The first annular channel 82 is connected to the inlet channel 81. There are two turntable 3 channels, each corresponding to the mounting platform 4 located on the turntable 3. The second annular channel 84 has two... Two second annular channels 84 are respectively opened on two mounting platforms 4. The second annular channel 84 is a circular channel. The second annular channel 84 passes through the mounting platform 4 and abuts one end of the turntable 3. The mounting platform 4 is installed on the turntable 3 to seal the second annular channel 84. One end of the channel of the turntable 3 is connected to the first annular channel 82, and the other end is connected to the second annular channel 84. There are two exhaust channels 85. The two exhaust channels 85 are respectively opened on two mounting platforms 4. One end of the exhaust channel 85 is connected to the second annular channel 84, and the other end passes through the center of the mounting platform 4. The exhaust channels 85 are connected to the first annular channel 82 and the second annular channel 84 through the channel of the turntable 3 to ensure the connection of the exhaust channel 8 when the turntable 3 and the mounting platform 4 rotate, thereby reducing the impact of the rotation of the turntable 3 and the mounting platform 4 on the exhaust.

[0031] Reference Figure 1The machine body 1 is equipped with an installation mechanism 11, which is located around the turntable 3 and corresponds to one of the mounting platforms 4. The installation mechanism 11 includes a hopper 111 mounted on the top of the frame 102, a feeding pipe 112 connected to and communicating with the hopper 111, and a feeding nozzle 113 mounted on the end of the feeding pipe 112 away from the hopper 111. The hopper 111 is used to store steel balls 03. The steel balls 03 stored in the hopper 111 are fed into the feeding nozzle 113 through the feeding pipe 112. The feeding nozzle 113 is equipped with a power pump 12, which provides power to the steel balls 03, driving the steel balls 03 in the feeding nozzle 113 to leave the feeding nozzle 113 from the outlet of the feeding nozzle 113. One end of the outlet of the feeding nozzle 113 faces the mounting platform 4. The machine body 1 is equipped with a drive mechanism 13, which includes a mounting plate 131 mounted on the platform 101. A drive cylinder 132 and a fixed plate 133 are mounted on the mounting plate 131. A feeding nozzle 113 is mounted on the fixed plate 133. A flexible hose is used for the feeding pipe 112. The drive cylinder 132 drives the fixed plate 133 to slide towards or away from the mounting platform 4, thereby driving the feeding nozzle 113 to slide towards or away from the mounting platform 4. When it is necessary to install steel balls 03 for the female connector 0, the drive mechanism 13 drives the feeding nozzle 113 to slide, so that the outlet of the feeding nozzle 113 is close to the female connector 0 and aligned with the steel ball hole 02 on the female connector 0. Then the feeding nozzle 113 feeds the steel ball 03 into the steel ball hole 02. The mounting platform 4 drives the female connector 0 to rotate, so that another steel ball hole 02 is aligned with the feeding nozzle 113. After all the steel ball holes 02 are filled, the drive mechanism 13 drives the feeding nozzle 113 to slide away from the mounting platform 4.

[0032] Reference Figure 1The machine body 1 is provided with a stamping mechanism 14, which is located on the mounting platform 4 away from the mounting mechanism 11. The stamping mechanism 14 includes a power component 141 mounted on the frame 102 directly above the mounting platform 4 and a stamping head 142 mounted on the side of the power component 141 facing the mounting platform 4. In this embodiment, the power component 141 is an electric cylinder, which drives the stamping head 142 to slide towards or away from the mounting platform 4. A cone 19 is fixed at one end of the pressure block 15, and the pressure block 15 presses against the female... When the connector is 0, the side of the fixed conical truncated cone 19 faces the power component 141; the stamping head 142 includes a mounting head 1421 fixed on the power component 141 and several stamping plates 1422 slidably disposed on the mounting head 1421. In this embodiment, four stamping plates 1422 are provided. The stamping plates 1422 are arc-shaped pieces. All four stamping plates 1422 slide towards or away from the center of the mounting head 1421. Through the sliding of the stamping plates 1422, the four stamping plates 1422 can form a direct non-linear relationship. The mounting head 1421 has four T-shaped grooves 16 corresponding to the stamping plate 1422. T-shaped sliders 17 are fixed on the stamping plate 1422 and slide within the T-shaped grooves 16. A stamping spring 18 is placed within the T-shaped grooves 16, driving the stamping plate 1422 to slide towards the center of the mounting head 1421. When the retaining ring 06 needs to be installed, it is fitted onto the truncated cone 19 of the pressure block 15, and then driven by the power component 141. The stamping head 142 slides toward the mounting platform 4, and the stamping plate 1422 drives the retaining ring 06 toward the female connector 0. The retaining ring 06 deforms under the guidance of the conical truss 19, and the stamping plate 1422 also slides away from the center of the mounting head 1421 under the guidance of the conical truss 19. When the retaining ring 06 leaves the pressure block 15 and enters the mounting position of the female connector 0, the retaining ring 06 springs back and is fixed on the female connector 0. Then, the stamping head 142 is driven to slide away from the mounting platform 4, and the stamping plate 1422 is reset under the elastic force of the stamping spring 18.

[0033] The implementation principle of this application embodiment is as follows: The operator stands on the mounting platform 4 on the side where the stamping mechanism 14 is located, installs the female connector 0 cylinder 01 on the mounting platform 4, and presses the pressure block 15 on the cylinder 01. Then, the turntable 3 is driven to rotate, rotating the mounting platform 4 with the cylinder 01 and pressure block 15 installed to the mounting mechanism 11. The mounting mechanism 11 installs and embeds steel balls 03 into the steel ball holes 02 on the cylinder 01. While installing the steel balls 03, the inside of the cylinder 01 is evacuated to reduce the probability of the steel balls 03 falling out. During this period, the operator installs another cylinder 01 and pressure block 15 on another mounting platform 4. After the steel balls 03 are installed, the turntable 3 is rotated to install the steel balls 03. The cylinder 01 is rotated to the bottom of the stamping mechanism 14, and at the same time, the cylinder 01 on another mounting platform 4 is sent to the mounting mechanism 11 for the installation of steel balls 03. The operator observes whether steel balls 03 have fallen from the steel ball hole 02 on the cylinder 01 below the stamping mechanism 14. If they fall, steel balls 03 are manually added to the hole. If they do not fall, the spring 04 and the telescopic sleeve 05 are put on the outside of the cylinder 01, and the retaining ring 06 is placed on the pressure block 15. Then the power component 141 is started to drive the stamping head 142 to drive the retaining ring 06 to be installed on the cylinder 01, completing the installation of the female connector 0 steel ball 03 area. After that, the female connector 0 is removed and replaced with a new female connector 0 cylinder 01 and the pressure block 15 is installed.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
