[0001] The present invention relates to the technical field of process tooling, and in particular to an assembly tool for conical and circular products and an assembly method thereof. Background Art

[0002] After a certain conical and circular thin-walled shell is filled with formed solid fuel, a pressure ring needs to be assembled to fix the fuel. The pressure ring is threadedly connected to the inside of the shell. It is necessary to fix and clamp the shell without damaging the surface of the conical and circular shell, and then screw the pressure ring in. To facilitate the operation of workers and ensure the assembly quality, special tools are required, namely a special wrench for the pressure ring and a tool that can fix and clamp the shell. Summary of the Invention

[0003] In view of this, the present invention designs a device that uses left and right claws similar to a split clamp with an eccentric wheel to clamp the outer shell of a conical and circular product, and then uses a special wrench to install the pressure ring into the product. Specifically, it is an assembly tool for conical and circular products and an assembly method thereof.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An assembly tool for conical and circular products includes a bracket. An eccentric adjustment wheel assembly is provided on one side of the bracket. An assembly hole is provided on the upper panel of the bracket. A clamping assembly is provided on the bracket above the assembly hole. One side of the clamping assembly is connected to the eccentric adjustment wheel assembly. The clamping distance of the clamping assembly is adjusted through the eccentric adjustment wheel assembly to clamp and release the workpiece.

[0006] It further includes a wrench assembly for assembling the pressure ring.

[0007] As a further improvement of the above technical solution:

[0008] As an optimized solution of the above technical solution, the clamping assembly includes a right claw fixedly provided on the bracket on the side away from the eccentric adjustment wheel assembly, a guide shaft provided on the side surface of the right claw close to the eccentric adjustment wheel assembly, a compression spring sleeved on the guide shaft, and a left claw slidably provided on the guide shaft. The other side of the left claw is in contact with the eccentric adjustment wheel assembly.

[0009] As an optimized solution of the above technical solution, both the guide shaft and the sliding hole of the left claw are stepped, and the compression spring is located between the opposite stepped surfaces of the guide shaft and the left claw.

[0010] As an optimized solution of the above technical solution, an arc-shaped claw groove is provided on the surface of the left claw opposite to the right claw, and a pressing rubber is provided on the inner wall of the arc-shaped claw groove.

[0011] As an optimized solution of the above technical solution, the eccentric adjustment wheel assembly includes an eccentric wheel rotatably arranged on the upper surface of the bracket through an eccentric shaft, and a handle rod arranged on one side of the eccentric wheel. The connection point between the eccentric shaft and the eccentric wheel is not the center of the circle.

[0012] As an optimized solution of the above technical solution, a stop screw is screwed on the side of the upper panel of the bracket. When the stop screw is screwed to the deepest position, it can contact the eccentric shaft.

[0013] As an optimized solution of the above technical solution, a ball head is arranged at the end of the handle rod.

[0014] As an optimized solution of the above technical solution, a rubber pad is arranged on the lower panel of the bracket, and the rubber pad is located below the assembly hole.

[0015] As an optimized solution of the above technical solution, the wrench assembly includes a wrench body and wrench handles symmetrically arranged on both sides of the wrench body. A matching convex block that matches the process groove of the pressure ring is arranged below the wrench body.

[0016] The present invention also provides an assembly method for an assembly tool for a conical circular product, including the following steps:

[0017] Step1. Place the bracket on the workbench and fix the bracket with screws;

[0018] Step2. Place the rubber pad on the upper surface of the lower panel of the bracket and below the assembly hole;

[0019] Step3. Drive the eccentric adjustment wheel assembly to increase the distance between the clamping assemblies, then pass the housing through the distance between the clamping assemblies and then through the assembly hole, and place the lower end of the housing on the rubber pad;

[0020] Step4. Drive the eccentric adjustment wheel assembly again to reduce the distance between the clamping assemblies, thereby clamping the housing;

[0021] Step5. Place the pressure ring into the upper end of the housing and screw the pressure ring to the housing through the wrench assembly to complete the assembly;

[0022] Step6. Drive the eccentric adjustment wheel assembly to increase the distance between the clamping assemblies and take out the assembled component.

[0023] Compared with the existing technology, the beneficial effects of the present invention are:

[0024] 1. The tool provided by the present invention has a compact structure, is simple and convenient to use, is easy to clamp and remove without damaging the housing, ensuring the assembly quality. The one-key adjustment of the eccentric wheel assembly enables rapid adjustment of the clamping distance, significantly shortening the time for fixing and removing the housing, improving the production efficiency. At the same time, the eccentric wheel adjustment mechanism allows the clamping assembly to adapt to conical and circular housings of different sizes, expanding the application range of the tool and reducing the cost of dedicated tools for multi-specification products.

[0025] 2. The arc-shaped claw groove designed for the claw of the present invention fits the shape of the conical and circular housing. Combined with the elastic buffer of the pressing rubber, it avoids direct contact between the metal claw and the housing surface, significantly reducing the risk of scratches, indentations or deformations. At the same time, the rubber pad provided at the bottom buffers and provides flexible support to prevent damage to the bottom of the housing due to rigid contact.

[0026] 3. The present invention provides reinforcement with a stop screw. By screwing the stop screw to limit the position of the eccentric shaft, it further ensures the reliability of the clamping state.

[0027] 4. For the wrench assembly provided by the present invention, the matching convex block provided at the lower end precisely fits the process groove of the pressure ring, ensuring uniform force when the pressure ring is screwed in, avoiding slipping or misalignment, reducing repeated adjustments, and improving the assembly speed.

[0028] In summary, the tool provided by the present invention solves the problems of easy damage, low efficiency, and poor quality consistency during the assembly process of conical and circular thin-walled housings, combines high efficiency, safety and economy, and reduces the rejection rate at the same time.

Detailed Description of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] As shown in the attached Figure 1 to the attached Figure 4 figures, the technical solution of this embodiment mainly includes two parts: 1. The clamping part of the housing 17; 2. The screwing part of the pressing ring 18.

[0038] As shown in the attached Figures 1 to 3 figures, for the clamping part of the housing 17, all components are installed on the bracket 1. The bracket 1 is mainly composed of a lower panel, an upper panel, and support plates provided at both left and right ends of the upper panel. An assembly hole 2 is provided on the upper panel of the bracket 1.

[0039] The parts provided on the upper panel of the bracket 1 include an eccentric adjustment wheel component and a clamping component. Waist-shaped holes are provided around the lower panel for fixing the whole on the workbench with screws.

[0040] For the clamping assembly, its structure specifically includes two claws, namely the left claw 6 and the right claw 3. Arc-shaped claw grooves are provided on the opposite surfaces of the two claws. By reducing and expanding the distance between the two arc-shaped claw grooves, the clamping and loosening of the housing 17 are realized. Therefore, in order to prevent damage to the housing 17 during the clamping process, a pressing rubber 7 is pasted on the inner wall of the arc-shaped claw groove with glue.

[0041] For the right jaw 3, it is arranged at the right end of the upper panel of the bracket 1 and fixed from bottom to top by screws. At the same time, a guiding shaft 4 is arranged on the left end face of the right jaw 3. The two guiding shafts 4 are located at both ends of the arc-shaped jaw groove. At the same time, the left end of the guiding shaft 4 is small and the right end is large, showing a stepped shape. A compression spring 5 is sleeved on the front end of the guiding shaft 4;

[0042] On the face of the left jaw 6 opposite to the right jaw 3, a through-hole is arranged. At the same time, the through-hole is also small at the left end and large at the right end, showing a stepped shape. The left jaw 6 is inserted into the guiding shaft 4 through the through-hole. The compression spring 5 is located between the relative stepped surfaces of the guiding shaft 4 and the through-hole, thereby limiting both ends of the compression spring 5 and making it compressible. Therefore, the left jaw 6 is slidably arranged compared with the right jaw 3.

[0043] At the same time, an eccentric adjustment wheel component is arranged on the left side of the left jaw 6. Its specific structure is as follows: the upper and lower ends of the eccentric shaft 8 have threads and are installed on the upper panel of the bracket 1. The lower end is locked with a nut and washer. The upper end of the eccentric shaft 8 is sleeved with an eccentric wheel 9 and then installed with a nut and washer. There is a gap between the lower plane of the washer at the upper end of the eccentric wheel 9 and the upper plane of the eccentric wheel 9, ensuring that the eccentric wheel 9 can rotate around the eccentric shaft 8;

[0044] The right side of the eccentric wheel 9 is in contact with the left side face of the left jaw 6. At the same time, the connection point between the eccentric wheel 9 and the eccentric shaft 8 is not at the center position of the eccentric wheel 9, so that the rotation of the eccentric wheel 9 cooperates with the compression spring 5 to realize the change of the distance between the left jaw 6 and the right jaw 3;

[0045] A handle rod 10 is also screwed on the side of the eccentric wheel 9. For the convenience of taking, a ball head 12 is screwed on the other end of the handle rod 10.

[0046] In order to fix the eccentric shaft 8 and prevent it from rotating, a set screw 11 is screwed on the side face of the upper panel of the bracket 1. The set screw 11 is screwed to the deepest position and can contact the eccentric shaft 8. By screwing the set screw 11, the eccentric shaft 8 is tightened to realize the fixation of the eccentric shaft 8 and prevent it from rotating, ensuring that there will be no loosening during the process of clamping the housing 17.

[0047] In order to prevent the bottom of the housing 17 from being damaged during the processing, a rubber pad 13 is installed and placed at the position of the lower panel of the bracket 1 below the assembly hole 2 to protect the lower end of the housing 17.

[0048] In the above position relationship, although the eccentric wheel 9, the left jaw 6 and the right jaw 3 are arranged from left to right respectively, the position can be reversed, that is, the right jaw 3, the left jaw 6 and the eccentric wheel 9 can be arranged from left to right. From this, it can be known that there is no special requirement for the position relationship, as long as the position that meets the above functions is the same as the technical solution of the present invention.

[0049] As shown in the appendix Figure 3As shown in the attached Figure 4 Shown in Figure 4 , it is the tightening part of the compression ring 18. Its main structure is the wrench body 14. In order to facilitate the rotation of the wrench body 14, wrench handles 15 are symmetrically arranged on the left and right sides of the wrench body 14.

[0050] In order to be able to match the compression ring 18, a matching convex block 16 that matches the process groove of the compression ring 18 is provided on the lower end surface of the wrench body 14 to ensure uniform force when the compression ring 18 is screwed in, avoid slipping or misalignment, reduce repeated adjustment, and improve the assembly speed.

[0051] As shown in the attached Figure 3 Shown in Figure 3 , the usage process of this technical solution is as follows:

[0052] Step 1: Place the bracket 1 on the workbench and fix the bracket 1 with screws.

[0053] Step 2: Place the rubber pad 13 on the upper surface of the lower panel of the bracket 1 and below the assembly hole 2.

[0054] Step 3: Grasp the handle rod 10 and rotate the eccentric wheel 9, so that the left claw 6 moves to the left under the action of the compression spring 5, increasing the distance between the left claw 6 and the right claw, and then passing the housing 17 through between the left claw 6 and the right claw 3, and then through the assembly hole 2, and placing the lower end of the housing 17 on the rubber pad 13 on the lower panel of the bracket 1.

[0055] Step 4: Grasp the handle rod 10 again and rotate the eccentric wheel 9, so that the left claw 6 moves to the right under the action of the eccentric wheel 9, reducing the distance between the left claw 6 and the right claw, thereby clamping the housing 17. At this time, the compression spring 5 is in a continuously compressed state.

[0056] Step 5: Put the compression ring 18 into the upper end of the housing 17, hold the wrench handles 15 on both sides with both hands, so that the matching convex block 16 is stuck into the process groove of the ring, and control the wrench handles 15 with both hands to rotate the wrench body 14 to complete the screwing connection between the housing 17 and the compression ring 18, thereby completing the assembly.

[0057] Step 6: Repeat the operation method in Step 3 to take out the assembled component.

[0058] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
