Description

Technical Field

[0001] This application relates to the field of pipe fitting clamps, and in particular to quick-connect coupling disassembly clamps. Background Technology

[0002] Injection molding machines use the thrust of a screw (or plunger) to inject pre-plasticized molten plastic into a closed mold cavity. After solidification and shaping, hydraulic oil is introduced into the mold to provide hydraulic pressure to open the mold and obtain the product.

[0003] Most existing oil tank outlets are connected to molds via quick-connect couplings. These couplings consist of a detachable male and female connector. The female connector has a retractable ball bearing on its inner wall, while the male connector has a groove on its outer wall that matches the ball bearing. During assembly, the ball bearing extends and embeds itself in the groove. During disassembly, the female connector is manually pulled to spring the ball bearing back from the groove, thus separating the male and female connectors. When hydraulic oil operates at high temperatures for extended periods, impurities will precipitate. As the quick-connect coupling is used repeatedly, these impurities will adhere to the ball bearing on the female connector, easily causing the ball bearing to get stuck when disassembling the quick-connect coupling. This requires considerable effort from the operator to disassemble the quick-connect coupling.

[0004] The existing technical solutions mentioned above have the following drawbacks: when workers forcefully disassemble the quick-connect couplings, a small amount of high-temperature hydraulic oil is still sealed inside the quick-connect couplings. When operators directly touch and disassemble the male and female connectors, the high-temperature hydraulic oil is easily splashed out, causing burns to the workers. Utility Model Content

[0005] This application provides a quick-connect coupling disassembly fixture to improve the efficiency of quick-connect coupling disassembly, increase production efficiency and safety.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] The quick-connector disassembly fixture includes a first half-ring, one end of which is rotatably connected to a second half-ring. Clamping components are provided on both the second and first half-rings away from the rotatable connection. Ejection components are provided on both the first and second half-rings. Each ejection component includes a fixed tube, within which a rotating platform is slidably mounted. A push rod is fixed to one side of the rotating platform. A sliding platform is machined on the rotating platform, comprising a first inclined surface, a groove, and a second inclined surface. A rotating shaft passes through the rotating platform, and a sliding block is machined on the rotating shaft. One end of the rotating shaft is connected to a transmission component, which includes a cylindrical head rotatably connected to one end of the fixed tube and to one end of the rotating shaft. One end face of the cylindrical head is machined with a countersunk hexagonal hole that mates with an internal hexagonal wrench.

[0008] By adopting the above technical solution, an Allen wrench is inserted into the cylindrical head and rotated, causing the transmission component to drive the ejector rod in the ejector component to extend. The ejector rod can abut against the male end of the quick-connect coupling or the mold. The thrust when the ejector rod extends pushes the clamp to push the female end of the quick-connect coupling out of the male end, realizing the separation of the male and female ends of the quick-connect coupling. This reduces the direct contact between workers and the quick-connect coupling when disassembling it, reduces the risk of hot hydraulic oil splashing out and burning workers, improves the disassembly efficiency of the quick-connect coupling, and improves production efficiency and safety.

[0009] Optionally, a first keyway is machined on one side of the cylindrical head, and one end of the rotating shaft passes through the cylindrical head and is machined with a first sliding key that cooperates with the first keyway.

[0010] By adopting the above technical solution, the first keyway and the first sliding key cooperate to ensure a stable connection between the rotating shaft and the transmission component.

[0011] Optionally, two rotating platforms are symmetrically arranged and located at both ends of the sliding block, and a first elastic element is sleeved on the peripheral wall of the top rod. The first elastic element is located at the end of the rotating platform and the fixed tube connected to the top rod, near the top rod.

[0012] By adopting the above technical solution, the two rotating tables can increase the length of the push rod extending out of the fixed tube. The thrust of the first elastic element can assist in pushing the push rod to reset and ensure that the push rod is firmly fixed in the fixed tube after reset. The first keyway and the first sliding key cooperate to ensure a stable connection between the rotating shaft and the transmission assembly, reduce the risk of burns caused by hot hydraulic oil splashing when workers directly contact the quick connector, improve the disassembly efficiency of the quick connector, and improve production efficiency and safety.

[0013] Optionally, the slope of the first inclined plane is less than the slope of the second inclined plane.

[0014] By adopting the above technical solution, the first inclined surface with a smaller slope facilitates the ejection of the jacking rod and makes it easier for workers to reset the jacking rod. The second inclined surface with a larger slope can assist in pushing the jacking rod to reset and ensure that the jacking rod is firmly fixed in the fixed pipe after reset.

[0015] Optionally, the end face of the sliding block is machined to form an arc surface that fits into the groove.

[0016] By adopting the above technical solution, the push rod can be kept at the maximum distance extending out of the fixed tube. The two rotating tables can increase the length of the push rod extending out of the fixed tube, making it easier for workers to remove the female end of the quick connector from the male end.

[0017] Optionally, the clamping assembly includes a fixing rod, which is rotatably connected to the first half-ring. One end of the fixing rod passes through the second half-ring and is rotatably connected to an eccentric wheel. A handle is fixedly connected to the eccentric wheel, and a fixing seat that fits against the eccentric wheel is machined on the second half-ring.

[0018] By adopting the above technical solution, the number of operation steps when fixing and disassembling fixtures can be reduced, making it easier for workers to assemble and disassemble fixtures, improving fixture disassembly efficiency, and increasing production efficiency.

[0019] Optionally, a positioning block is machined on the first half-ring, and a positioning groove that mates with the positioning block is formed on the second half-ring.

[0020] By adopting the above technical solution, the positioning block and the positioning groove work together to ensure that the first half ring and the second half ring can be smoothly connected.

[0021] Optionally, silicone pads are fixed to both the first half-ring and the second half-ring.

[0022] By adopting the above technical solution, the friction between the first half-ring and the second half-ring and the quick-connect female head can be increased, ensuring that the clamping assembly can firmly fix the clamp on the quick-connect female head.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a first half-ring, a second half-ring, a transmission assembly, an ejection assembly, and an ejector rod, the thrust of the ejector rod when it extends will cause the clamp to push the female end of the quick connector out of the male end, realizing the separation of the male and female ends of the quick connector. This can reduce the direct contact between the workers and the quick connector when disassembling the quick connector, reduce the risk of hot hydraulic oil remaining in the quick connector splashing out and burning the workers, improve the disassembly efficiency of the quick connector, and improve production efficiency and safety.

[0025] 2. By setting up a rotating table, a sliding table, and a sliding block, the length of the push rod extending out of the fixed tube is increased. The thrust of the first elastic element can assist in pushing the push rod to reset and ensure that the push rod is firmly fixed in the fixed tube after reset. The first keyway and the first sliding key cooperate to ensure a stable connection between the rotating shaft and the transmission assembly, reduce the risk of burns caused by hot hydraulic oil splashing when workers directly contact the quick connector, improve the disassembly efficiency of the quick connector, and improve production efficiency and safety.

[0026] 3. By incorporating silicone pads, the friction between the first and second half-rings and the quick-connect female head is increased, ensuring that the clamping assembly can securely fix the clamp to the quick-connect female head. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a quick-connect coupling disassembly fixture, as shown in the embodiments below. Figure 1 and Figure 2 The clamp includes a first half-ring 1, one end of which is rotatably connected to a second half-ring 2. The first half-ring 1 and the second half-ring 2 can be spliced ​​into a ring. A clamping assembly 3 is provided on the side of the first half-ring 1 and the second half-ring 2 away from the rotatable connection. The clamping assembly 3 includes a fixing rod 31, which is rotatably connected to a section of the first half-ring 1 away from the rotatable connection with the second half-ring 2. The end of the fixing rod 31 away from the first half-ring 1 passes through the second half-ring 2, and the fixing rod 31 passes through the end face of the first half-ring 1 and the second half-ring 2 away from the rotatable connection. A positioning block 11 is machined on the end face of the first half-ring 1 through which the fixing rod 31 passes. Two blocks are symmetrically arranged. The second half-ring 2 has a positioning groove 21 that cooperates with the positioning block 11. The end of the fixing rod 31 away from the first half-ring 1 is rotatably connected to the eccentric wheel 32. The side of the eccentric wheel 32 away from the second half-ring 2 is welded with a handle 33. The part of the handle 33 away from the eccentric wheel 32 is curved into an arc shape and the end of the handle 33 away from the eccentric wheel 32 is located outside the first half-ring 1. The part of the second half-ring 2 near the fixing rod 31 is machined to form a fixing seat 22. The end face of the fixing seat 22 near the eccentric wheel 32 is in contact with the peripheral wall of the eccentric wheel 32. The inner walls of the first half-ring 1 and the second half-ring 2 are both glued with silicone pads 34.

[0032] When using this clamp, the silicone pad 34 increases the friction between the first half-ring 1 and the second half-ring 2 and the quick-connect female head, ensuring that the clamping assembly 3 can firmly fix the clamp onto the quick-connect female head. The positioning block 11 and the positioning groove 21 cooperate to ensure that the first half-ring 1 and the second half-ring 2 can be smoothly connected. Rotating the handle 33 causes the eccentric wheel 32 to rotate on the fixed seat 22, and pulling the fixing rod 31 towards the fixed seat 22 makes the first half-ring 1 and the second half-ring 2 closely fit together near the clamping assembly 3, so that the first half-ring 1 and the second half-ring 2 are spliced ​​into a ring and Fixed to the peripheral wall of the quick-connect female head, when it is necessary to remove the clamp from the quick-connect female head, the handle 33 is rotated in the opposite direction to make the eccentric wheel 32 rotate on the fixed seat 22, so that the distance between the fixed seat 22 and the rotation shaft 44 of the eccentric wheel 32 is reduced, and the fixed rod 31 is rotated to make the eccentric wheel 32 move away from the fixed seat 22. At this time, the first half ring 1 and the second half ring 2 can rotate freely, so as to remove the clamp from the quick-connect female head. The clamping assembly 3 can reduce the operation steps when fixing and disassembling the clamp, making it easier for workers to disassemble and assemble the clamp, improving the clamp disassembly efficiency and increasing production efficiency.

[0033] Reference Figure 2 Both the first half-ring 1 and the second half-ring 2 are provided with ejector components 4. The ejector components 4 include a fixed tube 41, one end of which is machined into a constriction 411. The fixed tube 41 is welded to the outer wall of the first half-ring 1 or the second half-ring 2. A rotating platform 42 is slidably arranged inside the fixed tube 41. A sliding platform 43 is machined on the end face of one end of the rotating platform 42. The sliding platform 43 includes a first inclined surface 431, a groove 432, and a second inclined surface 433. The first inclined surface 431, the groove 432, and the second inclined surface 433 are connected end to end along the peripheral wall of the rotating platform 42, and are connected during rotation. Two sliding platforms 43 are centrally symmetrically arranged on the platform 42. The two ends of the groove 432 are respectively connected to the top of the first inclined surface 431 and the second inclined surface 433. The slope of the first inclined surface 431 is less than that of the second inclined surface 433. A rotating shaft 44 is inserted inside the rotating platform 42. A sliding block 441 is formed on the peripheral wall of the rotating shaft 44. Two sliding blocks 441 are symmetrically arranged along the peripheral wall of the rotating shaft 44. The two sliding blocks 441 correspond one-to-one with the two sets of sliding platforms 43, and the end of the sliding block 441 near the rotating platform 42 is formed into an arc surface that fits with the groove 432.

[0034] Reference Figure 2Two rotating platforms 42 are provided and are symmetrically arranged at both ends of the sliding block 441 along its length. A top rod 45 is welded to the rotating platform 42 near the constriction 411 of the fixed tube 41. The end of the top rod 45 away from the rotating platform 42 extends out of the constriction 411 of the fixed tube 41. A first elastic element 46 is sleeved on the peripheral wall of the top rod 45. In this embodiment, the first elastic element 46 is a spring. The two ends of the first elastic element 46 abut against the constriction 411 of the fixed tube 41 and the rotating platform 42, respectively. The rotating platform 42 away from the constriction 411 of the fixed tube 41 is welded to the inner wall of the fixed tube 41. One end of the rotating shaft 44 extends out of the rotating platform 42 away from the constriction 411 of the fixed tube 41 and is connected to the transmission assembly 5.

[0035] When this fixture is used, the rotating shaft 44 drives the sliding block 441 to slide along the first inclined surface 431 on the rotating table 42, so as to push the rotating table 42 near the constriction 411 to move along the fixed tube 41 towards the constriction 411. At the same time, it drives the ejector rod 45 to extend out of the constriction 411, so that one end of the ejector rod 45 abuts against the male end of the quick connector or the mold, and pushes the fixture to drive the female end of the quick connector to disengage from the male end. When the rotating shaft 44 drives the slider to continue to rotate into the groove 432, one end face of the sliding block 441 fits against the inner wall of the groove 432. At this time, the ejector rod 45 reaches the maximum distance of extending out of the fixed tube 41. The groove 432 can keep the ejector rod 45 extending out of the fixed tube 41 at the maximum distance. The two rotating tables 42 can increase the length of the ejector rod 45 extending out of the fixed tube 41, making it easier for the operator to remove the female end of the quick connector from the male end.

[0036] After the male and female ends of the quick-connect coupling are separated, the rotating shaft 44 continues to rotate, causing the slider to disengage from the groove 432 and slide along the second inclined surface 433 to the connection point between the second inclined surface 433 and the first inclined surface 431. At this time, the push rod 45 is completely retracted into the fixed tube 41 and reset. The first inclined surface 431 with a smaller slope facilitates the push rod 45 to be pushed out, making it easier for the operator to reset the push rod 45. The second inclined surface 433 with a larger slope can assist in pushing the push rod 45 to reset and ensure that the push rod 45 is firmly fixed in the fixed tube 41 after reset. The rotating shaft 44 drives the slider to rotate and reset the push rod 45, reducing the operation steps of resetting the push rod 45 and making it easier for the operator to reset the push rod 45. The thrust of the first elastic element 46 can assist in pushing the push rod 45 to reset and ensure that the push rod 45 is firmly fixed in the fixed tube 41 after reset. The ejector assembly 4 pushes the ejector rod 45 to separate the male and female ends of the quick-connect coupling, reducing the risk of burns caused by hot hydraulic oil splashing when workers directly contact the quick-connect coupling, improving the disassembly efficiency of the quick-connect coupling, and increasing production efficiency and safety.

[0037] Reference Figure 2The transmission assembly 5 includes a cylindrical head 51, which is rotatably connected to the end of the fixed tube 41 away from the constriction 411. The end of the rotating shaft 44 away from the rotating table 42 is inserted into the cylindrical head 51 and is machined with a first sliding key 442. A first keyway 52 that mates with the first sliding key 442 is machined on the inner side of the cylindrical head 51. An internal hexagon countersunk hole 53 that mates with an internal hexagon wrench is machined on the end of the cylindrical head 51 away from the fixed tube 41.

[0038] When using this fixture, insert the Allen wrench into the countersunk hole 53 of the cylindrical head 51 and rotate it. At this time, the first keyway 52 of the cylindrical head 51 engages with the first sliding key 442. When the cylindrical head 51 rotates, it drives the rotating shaft 44 to rotate, causing the ejector rod 45 of the ejector assembly 4 to extend. The engagement of the first keyway 52 and the first sliding key 442 ensures a stable connection between the rotating shaft 44 and the transmission assembly 5. After the male and female ends of the quick-connect coupling are separated, rotating the Allen wrench drives the cylindrical head 51 to rotate, causing the ejector rod 45 to return to its original position. This facilitates the worker in resetting the ejector rod 45 of the ejector assembly 4, improving the disassembly efficiency of the quick-connect coupling and enhancing both production efficiency and safety.

[0039] When using this fixture, the fixture is placed on the female end of the quick-connect coupling. The clamping assembly 3 clamps and fixes the fixture to the peripheral wall of the female end of the quick-connect coupling. The Allen wrench is inserted into the countersunk hole 53 of the cylindrical head 51 and rotated. The transmission assembly 5 drives the ejector rod 45 in the ejector assembly 4 to extend. The ejector rod 45 can abut against the male end of the quick-connect coupling or the mold. The thrust when the ejector rod 45 extends pushes the fixture to push the female end of the quick-connect coupling out of the male end, realizing the separation of the male and female ends of the quick-connect coupling. This reduces the direct contact between the workers and the quick-connect coupling when disassembling the quick-connect coupling, reduces the risk of hot hydraulic oil splashing out and burning workers, improves the disassembly efficiency of the quick-connect coupling, and improves production efficiency and safety.
