Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring sleeve cutting and positioning technology, specifically to rubber sealing ring sleeve cutting and positioning tooling. Background Technology

[0002] In the production process of rubber sealing rings, a slitting sleeve is a key tooling device commonly used to cut rubber tubing into sealing rings of a specified width. It is typically bolted to the output end of a drive unit, which drives it to rotate at high speed, thereby performing the slitting operation on the rubber tubing fitted onto its surface (the slitting sleeve is like...). Figure 10 (as shown);

[0003] Currently, the installation and replacement method for traditional slitting sleeves is as follows: When it is necessary to replace the slitting sleeve with one of a different diameter, the operator must first remove the multiple bolts (usually four) that secure the sleeve to the drive equipment. Only after disassembly can the original sleeve be removed and the new sleeve replaced. During installation, the bolts must be passed through the mounting holes on the new sleeve one by one and initially screwed into the threaded holes on the drive equipment end. Subsequently, the operator must use tools such as a torque wrench to tighten each bolt to the specified torque to ensure reliable connection.

[0004] As mentioned above, simply tightening the bolts does not guarantee the coaxiality between the slitting sleeve and the drive shaft. To avoid uneven slitting dimensions, reduced product quality, or equipment vibration due to excessive radial runout of the sleeve during the slitting process, dynamic alignment is necessary: ​​start the drive equipment to rotate the sleeve and observe for any runout. If the runout exceeds the allowable range, the machine must be stopped immediately, and the tightness of multiple fixing bolts must be readjusted. By repeatedly trying and correcting, the axial position of the sleeve is gradually adjusted until it is coaxial with the output shaft of the drive equipment.

[0005] However, this installation and commissioning method has the following drawbacks: First, the repeated disassembly and assembly of bolts and repeated start-up and shutdown of the equipment greatly reduces production efficiency and seriously affects the changeover speed; second, the coaxiality adjustment depends on the operator's experience, the accuracy is difficult to guarantee, and the process is cumbersome and labor-intensive. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rubber sealing ring sleeve cutting and positioning fixture, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rubber sealing ring sleeve cutting and positioning fixture includes a transmission box, in which a transmission motor is fixedly connected. A transmission rod is fixedly connected to the output end of the transmission motor. A docking assembly is rotatably connected to the surface of the transmission rod via a worm gear and worm wheel. An auxiliary cutting assembly is connected to one side of the docking assembly. A sealing ring sleeve is fitted onto the surface of the auxiliary cutting assembly. Positioning blocks are fixedly connected to the transmission box, and the transmission rod rotates within the positioning blocks. The auxiliary cutting assembly consists of an auxiliary replacement component and an auxiliary cutting component. One end of the docking assembly is connected to the auxiliary replacement component, and the auxiliary cutting component is mounted on the surface of the auxiliary replacement component. The sealing ring sleeve is fitted onto the surface of the auxiliary cutting component. The auxiliary cutting component includes a cutting cylinder, one end of which is fixedly connected to a blocking ring. The blocking ring has symmetrically arranged fixing holes on its surface and an internally threaded hole in its center.

[0009] Furthermore, the auxiliary replacement component includes a long rod, one end of which is fixedly connected to a connecting plate. The connecting plate has through holes spaced at equal intervals on one side, and there are four sets of through holes.

[0010] Furthermore, the auxiliary replacement component includes a blocking disc, the other end of the long rod is fixedly connected to the blocking disc, and a connecting stud is fixedly connected to the middle of one end of the blocking disc. The surface of the connecting stud is threadedly connected to the cutting cylinder through an internal threaded hole.

[0011] Furthermore, the auxiliary replacement component includes an annular groove, and the other end of the blocking disc is provided with an annular groove. An L-shaped ring is rotatably connected in the annular groove. One end of the L-shaped ring is fixedly connected to a long rod ring. A translation groove is symmetrically provided on one side of the long rod ring. An adjusting bolt is rotatably connected in the translation groove. The surface of the adjusting bolt is threaded with a hook.

[0012] Furthermore, the auxiliary replacement component includes an internally threaded cylinder, and the other end of the blocking disc is fixedly connected to the internally threaded cylinder inside the annular groove. An externally threaded cylinder is connected to the internal thread of the internally threaded cylinder, and an abutment nut is fixedly connected to one end of the externally threaded cylinder.

[0013] Furthermore, the docking assembly includes a rotating shaft, which is rotatably connected inside the transmission box. The surface of the transmission rod is rotatably connected to the rotating shaft via a worm gear and worm wheel.

[0014] This utility model provides a tooling for cutting and positioning rubber sealing ring sleeves. Compared with the prior art, it has the following advantages:

[0015] 1. When it is necessary to replace the slitting components (slitting cylinder and retaining ring) later, first tighten the adjusting bolt to disengage one end of the hook claw from the fixing hole. After disengagement, tighten the slitting cylinder. As the slitting cylinder rotates, it can be removed from the docking stud. This facilitates the replacement of slitting cylinders and retaining rings of different diameters later. At the same time, it can also prevent the replacement slitting cylinder from being out of concentricity with the auxiliary replacement components and docking components.

[0016] 2. The L-shaped ring can rotate freely in the ring groove, driving the long rod ring and hook to rotate synchronously, which facilitates quick alignment of the hook with the fixing hole and the mutual cooperation of the adjusting bolt and the translation groove. It can be accurately inserted into the fixing hole of the blocking ring to achieve secondary fixing of the slitting cylinder.

[0017] 3. A threaded connection is formed by connecting the stud and the internal threaded hole of the slitting cylinder, which not only ensures the connection between the slitting cylinder and the auxiliary replacement parts, but also realizes the convenient disassembly and assembly of the slitting cylinder, and can meet the replacement needs of slitting cylinders of different diameters.

[0038] Example

[0039] To address the technical problems in the background section, the following rubber sealing ring sleeve cutting and positioning fixture is provided:

[0040] Combination Figures 1-10As shown, the rubber sealing ring sleeve cutting and positioning fixture provided by this utility model includes a transmission box 100. A transmission motor 200 is fixedly connected inside the transmission box 100. A transmission rod 300 is fixedly connected to the output end of the transmission motor 200. A docking assembly 400 is rotatably connected to the surface of the transmission rod 300 through a worm gear and worm wheel. An auxiliary cutting assembly 500 is connected to one side of the docking assembly 400. A sealing ring sleeve 600 is fitted onto the surface of the auxiliary cutting assembly 500. Positioning blocks 700 are fixedly connected inside the transmission box 100. The moving rod 300 rotates within the positioning block 700; the auxiliary slitting assembly 500 consists of an auxiliary replacement component and an auxiliary slitting component, one end of the docking assembly 400 is connected to the auxiliary replacement component, the auxiliary slitting component is mounted on the surface of the auxiliary replacement component, and the sealing ring sleeve 600 is fitted onto the surface of the auxiliary slitting component; the auxiliary slitting component includes a slitting cylinder 501, one end of the slitting cylinder 501 is fixedly connected to a blocking ring 502, the surface of the blocking ring 502 is symmetrically provided with fixing holes 503, and the middle of the blocking ring 502 is provided with an internal threaded hole 504.

[0041] The transmission motor 200 drives the transmission rod to rotate, thereby driving the rotation of multiple sets of docking components and auxiliary cutting components to achieve synchronous cutting of multiple sets of sealing ring sleeves.

[0042] The internal threaded hole 504 and fixing hole 503 on the slitting cylinder 501 and the blocking ring 502 facilitate the later connection and fixing of the auxiliary slitting component and the auxiliary replacement component.

[0043] In this embodiment, the auxiliary replacement component includes a long rod 505, one end of which is fixedly connected to a connecting plate 506. A through hole 507 is provided at equal intervals on one side of the connecting plate 506, and four sets of through holes 507 are provided.

[0044] The auxiliary cutting assembly 500 and the docking assembly 400 can be easily connected together by four sets of through holes that are evenly spaced and multiple sets of screws.

[0045] In this embodiment, the auxiliary replacement component includes a blocking disc 508. The other end of the long rod 505 is fixedly connected to the blocking disc 508. A connecting stud 509 is fixedly connected to the middle of one end of the blocking disc 508. The surface of the connecting stud 509 is threadedly connected to the slitting cylinder 501 through an internal threaded hole 504.

[0046] By connecting the stud to the internal threaded hole of the slitting cylinder to form a threaded connection, the connection between the slitting cylinder and the auxiliary replacement parts is ensured, the slitting cylinder is easily disassembled and assembled, and the replacement needs of slitting cylinders of different diameters can be met (the internal threaded hole diameter is the same for all slitting cylinders of different diameters).

[0047] In this embodiment, the auxiliary replacement component includes an annular groove 510. The other end of the blocking disc 508 is provided with an annular groove 510. An L-shaped ring 511 is rotatably connected in the annular groove 510. One end of the L-shaped ring 511 is fixedly connected to a long rod ring 512. A translation groove 513 is symmetrically provided on one side of the long rod ring 512. An adjusting bolt 514 is rotatably connected in the translation groove 513. A hook 515 is threaded onto the surface of the adjusting bolt 514.

[0048] The hook can slide in the translation groove by adjusting the bolt, and can be precisely inserted into the fixing hole of the blocking ring to achieve secondary fixation of the slitting cylinder 501;

[0049] The L-shaped ring can rotate freely within the groove, causing the long rod ring and hook to rotate synchronously, making it easy for the hook to quickly align with the fixing hole.

[0050] In this embodiment, the auxiliary replacement component includes an internal threaded cylinder 516. The other end of the blocking disc 508 is fixedly connected to the internal threaded cylinder 516 inside the annular groove 510. An external threaded cylinder 517 is threadedly connected to the internal threaded cylinder 516. One end of the external threaded cylinder 517 is fixedly connected to an abutment nut 518.

[0051] By connecting the internal and external threaded cylinders, rotating the contact nut can push it towards the long rod ring until the contact nut and the long rod ring are in close contact. The friction between the two locks the long rod ring between the "blocking disc + contact nut", completely restricting the rotational freedom of the long rod ring and ensuring that the claw is always stably engaged in the fixed hole.

[0052] In this embodiment, the docking assembly 400 includes a rotating shaft 401. The rotating shaft 401 is rotatably connected inside the transmission box 100. The surface of the transmission rod 300 is rotatably connected to the rotating shaft 401 through a worm gear and worm wheel. One end of the rotating shaft 401 is fixedly connected to a docking plate 402. Four sets of threaded holes 403 are provided at equal intervals on one side of the docking plate 402.

[0053] By matching the four sets of equally spaced threaded holes on the mating plate with the four sets of through holes on the connecting plate, and symmetrically connecting them with four sets of screws—in conjunction with the operation of "adjusting the screw tightness with a torque wrench" during operation—the centers of the mating plate and the connecting plate can be completely aligned, thereby achieving concentricity of the entire "transmission rod-rotating shaft-auxiliary replacement parts-slitting cylinder" chain, minimizing eccentric vibration during slitting, and improving the slitting accuracy of the sealing ring sleeve.

[0054] Working principle and usage process of this utility model:

[0055] During installation,

[0056] The first step is to connect the auxiliary replacement component to the docking assembly 400:

[0057] During connection, firstly, one side of the connecting plate 506 is brought into contact with one side of the mating plate 402. After contact, the operator aligns the through hole 507 on the connecting plate 506 with the threaded hole 403. After alignment, the operator passes one end of the screw through the through hole 507 and threads it into the threaded hole 403. After connection, the operator uses a torque wrench to adjust the tightness of the four screws to ensure that the concentricity of the mating plate 402 and the connecting plate 506 is at the same point after connection. After connection, the connection between the mating assembly 400 and the auxiliary replacement component is completed.

[0058] The second step is to connect the auxiliary replacement component with the auxiliary cutting component and assemble them into an auxiliary cutting assembly:

[0059] During the docking process, firstly, align the end of the slitting cylinder 501 with the internal threaded hole 504 with the connecting stud 509 and screw it in, so that the connecting stud 509 forms a threaded connection with the blocking ring 502 and the slitting cylinder 501 through the internal threaded hole 504. When one side of the blocking ring 502 contacts one side of the blocking disc 508, it means that the slitting cylinder 501 cannot be screwed in. At this point, the initial connection is completed.

[0060] After connection, rotate the long rod ring 512. As the long rod ring 512 rotates, it will drive the L-shaped ring 511 to rotate within the ring groove 510. At the same time, the long rod ring 512 will drive the adjusting bolt 514 and the hook 515 to rotate. When one end of the hook 515 is aligned with the fixing hole 503, the rotation of the long rod ring 512 will stop. At the same time, rotate the adjusting bolt 514. As the adjusting bolt 514 rotates, it will drive the hook 515 to slide within the translation groove 513. Simultaneously, the hook 515 will also be inserted into the fixing hole 503, thus achieving secondary fixation of the slitting cylinder 501 and the blocking ring 502.

[0061] After fixing, rotate the abutment nut 518. As the abutment nut 518 rotates, it will drive the external threaded cylinder 517 to rotate. As the external threaded cylinder 517 rotates, it will be threadedly connected to the internal threaded cylinder 516. As the abutment nut 518 rotates, it will also move towards one side of the long rod ring 512. When one side of the abutment nut 518 comes into contact with one side of the long rod ring 512, the long rod ring 512 can be fixed between the blocking plate 508 and the abutment nut 518 by friction, thus preventing the long rod ring 512 from rotating.

[0062] When using the sealing ring sleeve 600, the following steps should be taken:

[0063] First, the worker inserts the sealing ring sleeve 600 into one end of the cutting cylinder 501. After insertion, when one end of the sealing ring sleeve 600 comes into contact with one side of the retaining ring 502, the installation of the sealing sleeve 600 is completed.

[0064] After installation, start the drive motor 200. As the drive motor 200 works, it will drive the drive rod 300 to rotate. When the drive rod 300 rotates, it will drive multiple docking components 400 and auxiliary cutting components 500 to rotate through the worm gear and worm wheel. When the auxiliary cutting components 500 rotate, it will drive the sealing ring sleeve 600 to rotate. At this time, the external cutting blade moves closer to the sealing ring sleeve 600, thereby cutting the sealing ring sleeve 600 into multiple sealing rings.

[0065] When it is necessary to replace the slitting components (slitting cylinder 501 and retaining ring 502) later, first tighten the adjusting bolt 514 so that one end of the hook 515 disengages from the fixing hole 503. After disengagement, tighten the slitting cylinder 501. As the slitting cylinder 501 rotates, it can be removed from the docking stud 509. This facilitates the replacement of slitting cylinders 501 and retaining rings 502 of different diameters later. At the same time, it can also prevent the replaced slitting cylinder 501 from being out of concentricity with the auxiliary replacement components and docking components.
