The assembly machine ensures that the sealing ring is correctly installed during the drain valve assembly process through automated control, effectively avoiding the phenomenon of missing installation and improving product quality and production efficiency.

[0003] In the existing sealing ring assembly machine, during the sealing assembly, the drain valve is transferred to the turntable through the feeding device, the drain valves are transferred one by one to the bottom of the set device through the turntable, the sealing ring is set on the drain valve, and then the drain valve is rotated and discharged through the turntable.

[0021] 2. When the telescopic rod is pushed and squeezed, the angle between the two sides will increase, and the telescopic rod will drive the connecting piece to move, thereby pushing out the drain valve inside the clamp ring, and leading out the drain valve with the sealing ring installed;

[0022] 3.

[0024] 5. The strong magnetic plate is located directly below the sealing ring installation device. When the sealing ring is installed, the magnetic block will be attracted to the strong magnetic plate, thereby driving the shaft rod to move downward, causing the locking ring to move downward. The locking ring is clamped inside the two collars and the middle ring, thereby strengthening the locking of the two collars and the middle ring on the shaft rod, ensuring that the clamping assembly will not deviate or open and close during the installation of the sealing ring, thereby ensuring the position of the drain valve;

[0025] 6. The arc-shaped elastic strip can enhance the effective contact with drain valves of different specifications in the middle, thus avoiding the deformation of the side of the drain valve due to clamping. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0039] Reference Figure 1-Figure 10 , a drain valve sealing ring leak-proof assembly machine, comprising: an outer shell 1, a feed port and a discharge port opened on the outer shell 1, a fixing frame 2 fixed on the side of the outer shell 1, a sealing ring device for mounting on the fixing frame 2, a bottom plate 3 arranged in the middle of the outer shell 1 and a mounting plate 4 rotatably connected above the bottom plate 3, a plurality of U-shaped mounting ports opened on the mounting plate 4, a clamping assembly 5 arranged inside the mounting port, and the clamping assembly 5 is used to clamp the drain valve;

[0040] The clamping assembly 5 includes two clamping rings 51, a hinge 52, two connecting pieces 53 and a spring column 54. The two clamping rings 51 are symmetrically arranged and one end is rotatably connected through the hinge 52. An elliptical clamping space is formed between the two clamping rings 51, and an eight-shaped opening is formed at one end of the clamping ring 51 away from the hinge 52 for introducing a drain valve. The two connecting pieces 53 are respectively fixedly connected to both sides of the hinge 52. The two connecting pieces 53 and the clamping ring 51 form a scissor shape. The connecting piece 53 is used to drive the two clamping rings 51 to open and close. The two spring columns 54 are respectively fixedly connected to one end of the clamping ring 51 away from the hinge 52 and are fixedly connected to the inner side of the installation port.

[0041] A control component 6 is disposed between the connecting pieces 53 , and the control component 6 is used to control the angle between the two connecting pieces 53 .

[0042] In the embodiment of the application of the above technical solution, the drain valve to be processed is introduced into the installation port through the feed port. At this time, the drain valve will be clamped between the two clamping rings 51, and the drain valve is limited and clamped by the elliptical clamping space. The angle between the two connecting pieces 53 is adjusted by the control component 6. Since the connecting pieces 53 and the clamping rings 51 form a scissors shape, when the angle between the connecting pieces 53 becomes smaller, the spacing between the clamping rings 51 becomes smaller, and when the angle between the connecting pieces 53 becomes larger, the spacing between the clamping rings 51 becomes larger, and the drain valves of different diameters are effectively clamped and fixed, thereby ensuring the installation accuracy of the sealing ring and the installation efficiency of the sealing ring.

[0043] The preferred technical solution in this embodiment is:

[0044] Reference Figure 5 The hinge 52 includes two sleeve rings 521, a middle ring 522 and an axle rod 523. The two sleeve rings 521 are respectively fixedly connected to the upper and lower sides of a clamp ring 51, the middle ring 522 is fixedly connected to the middle part of the other clamp ring 51, and the axle rod 523 is inserted between the sleeve rings 521 and the middle ring 522.

[0045] The sleeve ring 521 and the middle ring 522 are both slidably mounted on the shaft 523, and the position of the shaft 523 is restricted, thereby ensuring that the clamping rings 51 on both sides can be opened and closed driven by the sleeve ring 521 and the middle ring 522, thereby clamping and fixing the drain valve.

[0046] Reference Figure 6-7 The control assembly 6 includes two sliding blocks 61, a fixed rod 62, two connecting rods 63 and a spring tube 64. A sliding groove is opened inside the side where the two connecting pieces 53 are close to each other. The two sliding blocks 61 are respectively slidably set inside the two sliding grooves. The two ends of the fixed rod 62 are elastically connected to the sliding blocks 61 respectively. The spring tube 64 is fixedly connected between the two connecting rods 63 to form a telescopic rod. The telescopic rod is vertically fixedly connected to the middle of the fixed rod 62.

[0047] The spring tube 64 is short in length and mainly plays a certain role of extension and buffering. When the telescopic rod is subjected to a pulling force toward the middle of the mounting plate 4, the entire telescopic rod will be driven to move, thereby driving the fixed rod 62 to move toward the middle of the mounting plate 4. During the movement of the fixed rod 62, the two sliding blocks 61 will be driven to slide inside the slide groove, thereby reducing the angle between the two connecting pieces 53. Since the connecting piece 53 and the clamping ring 51 form a scissor shape, the angle between the two clamping rings 51 will become smaller as the angle between the connecting pieces 53 becomes smaller, thereby clamping and fixing the drain valves of different diameters.

[0048] When the telescopic rod is pushed and squeezed, the angle between the two sides will increase, and at the same time, the telescopic rod drives the connecting piece 53 to move, thereby pushing out the drain valve inside the clamp ring 51, and leading out the drain valve with the sealing ring installed.

[0049] When the control component 6 is not squeezed or pulled by the linkage component 7 , the elasticity of the linkage component 7 will drive the control component 6 to reset.

[0050] Reference Figure 6-8 , the mounting plate 4 is provided with a plurality of sliding openings in an annular shape, one end of the sliding opening is communicated with the mounting opening, a linkage assembly 7 is arranged inside the sliding opening, the linkage assembly 7 comprises a sliding column 71, a bottom block 72, an extrusion block 73 and a pulling spring 74, the sliding column 71 is slidably arranged inside the sliding opening, one end of the telescopic rod is fixedly connected to the side of the sliding column 71, the extrusion block 73 is fixedly connected to the upper end of the sliding column 71, the bottom block 72 is fixedly connected to the bottom end of the sliding column 71, and is slidably arranged on the chassis 3, the pulling spring 74 is arranged horizontally, and one end is fixedly connected to the side of the sliding column 71, and the other end is fixedly connected to the middle of the mounting plate 4.

[0051] During the rotation of the mounting plate 4, the extrusion block 73 intermittently contacts the regulating component 8, thereby achieving the effect of moving the position of the control component 6. When the sliding column 71 is not affected by external force, it is located in the middle of the sliding mouth. The extrusion block 73 is squeezed to drive the sliding column 71 to slide back and forth inside the sliding mouth. When there is no external force, it will be reset under the action of the pull spring 74.

[0052] An arc-shaped depression is provided on one side of the bottom block 72 close to the drain valve, so that when the sliding column 71 moves toward the outside of the mounting plate 4, the drain valve can be pushed from multiple positions through the clamping assembly 5 and the bottom block 72, and the drain valve can be stably pushed onto the export conveyor belt, thereby preventing the drain valve from tipping over.

[0053] Reference Fig. 9 , a placement opening is provided in the middle of the chassis 3 and the mounting plate 4, and a regulating component 8 is provided inside the placement opening, and the regulating component 8 is used to control the position of the sliding column 71, and the regulating component 8 includes a telescopic column 81, a mounting frame 82, a pulling frame 83 and a pushing block 84, the telescopic column 81 is vertically fixedly connected inside the placement opening, the mounting frame 82 is a V-shaped frame, and is fixedly connected to the upper end of the telescopic column 81, one end of the mounting frame 82 is away from the feed port, and the other end is toward the discharge port, the pulling frame 83 and the pushing frame are respectively fixedly connected to the two ends of the mounting frame 82, the pulling frame 83 is used to pull the sliding column 71 to move toward the middle of the mounting plate 4, and the pushing frame is used to move the sliding column 71 to the edge of the mounting plate 4;

[0054] The pulling frame 83 is an arc-shaped bar frame and is arranged on a side away from the feed port. The pushing block 84 is a triangular block with its tip facing the discharge port.

[0055] A receiving block 10 is disposed on one side of the pulling frame 83 close to the center of the mounting plate 4 , and the extruding block 73 contacts the receiving block 10 during the rotation process.

[0056] The drain valve that enters the clamping assembly 5 from the feed port position is not stably clamped at first. When the linkage assembly 7 rotates with the mounting disk 4, the extrusion block 73 will first contact the pulling frame 83. Under the shape of the pulling frame 83, the extrusion block 73 will drive the sliding column 71 to move toward the middle of the mounting disk 4, thereby driving the control assembly 6 to move, so that the two clamping rings 51 are clamped to clamp drain valves of different diameters. When the drain valve moves to the position of the receiving block 10, the receiving block 10 is connected to the device signal of the sleeve sealing ring. When the receiving block 10 is squeezed, the sleeve sealing ring device is started. When the receiving block 10 is squeezed, it means that the drain valve has moved to the bottom of the sleeve sealing ring device, and the sleeve sealing ring can be processed, thereby improving the installation accuracy of the sealing ring.

[0057] After the sealing ring is installed, as the mounting plate 4 rotates, the extrusion block 73 is separated from the pulling frame 83, and the extrusion block 73 is reset under the action of the pulling spring 74. As the mounting plate 4 rotates, the extrusion block 73 will drive the clamping assembly 5 to be pushed toward the discharge port position under the action of the pushing block 84.

[0058] The same set of regulating components 8 is used to realize multiple position control changes of the rotating clamping component 5, thereby achieving the clamping and pushing out effects, optimizing the structure, and reducing the production cost of using sensors and motors.

[0059] Reference Fig.10 A locking assembly 9 is provided between the hinge 52 and the chassis 3, and the locking assembly 9 is used to fix the angle between the two clamp rings 51;

[0060] The locking assembly 9 includes a strong magnetic plate 91, a magnetic block 92 and a plurality of locking rings 93. The plurality of locking rings 93 are sleeved on the shaft 523, are made of elastic material, and are respectively located on the upper sides of the two sleeve rings 521 and the middle ring 522. The strong magnetic plate 91 is fixedly mounted on the chassis 3 and is close to the fixing frame 2. The magnetic block 92 is fixedly connected to the bottom end of the shaft 523.

[0061] The strong magnetic plate 91 is located directly below the sealing ring installation device. When the sealing ring installation begins, the magnetic block 92 will be magnetically attracted to the strong magnetic plate 91, thereby driving the shaft 523 to move downward, causing the locking ring 93 to move downward, and the locking ring 93 is clamped inside the two sleeve rings 521 and the middle ring 522, thereby strengthening the locking of the two sleeve rings 521 and the middle ring 522 on the shaft 523, ensuring that during the installation of the sealing ring, the clamping assembly 5 will not be offset and open and closed, thereby ensuring the position of the drain valve.

[0062] Reference Fig.10 The clamp ring 51 has two bayonet openings on its side, and an elastic strip 11 is disposed inside the bayonet opening. The elastic strip 11 is an arc-shaped strip made of elastic material.

[0063] The arc-shaped elastic strip 11 can enhance the effective contact with the drain valves of different specifications in the middle, thereby avoiding the clamping deformation of the side of the drain valve.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
