Abstract
Description
Technical Field
[0001] This utility model relates to the field of process tooling technology, and in particular to an assembly tool for conical products. Background Technology
[0002] After a certain conical thin-walled shell is filled with shaped solid fuel, a pressure ring needs to be installed to fix the fuel. The pressure ring is threaded to the inside of the shell. The shell needs to be fixed and clamped without damaging the surface of the conical shell before the pressure ring is screwed in. To facilitate worker operation and ensure assembly quality, special tools are required, namely a special wrench for the pressure ring and a tool that can fix and clamp the shell. Utility Model Content
[0003] In view of this, this utility model designs a device similar to a half-part, with left and right jaws equipped with an eccentric wheel to clamp the conical product shell, and then using a special wrench to install the pressure ring into the product. Specifically, it is an assembly tool for conical products.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An assembly tool for conical products includes a bracket, an eccentric adjusting wheel assembly on one side of the bracket, an assembly hole on the top plate of the bracket, a clamping assembly on the bracket above the assembly hole, and a clamping assembly on one side of the clamping assembly to adjust the clamping distance of the clamping assembly by means of the eccentric adjusting wheel assembly, thereby achieving clamping and releasing of the workpiece.
[0006] It also includes a wrench assembly for assembling a pressure ring.
[0007] As a further improvement to the above technical solution:
[0008] An optimized version of the above technical solution is that the clamping assembly includes a right jaw fixedly mounted on a bracket away from the eccentric adjusting wheel assembly, a guide shaft mounted on the side of the right jaw close to the eccentric adjusting wheel assembly, a compression spring sleeved on the guide shaft, and a left jaw slidably mounted on the guide shaft, with the other side of the left jaw in contact with the eccentric adjusting wheel assembly.
[0009] An optimized version of the above technical solution is that the sliding holes of the guide shaft and the left chuck are both stepped, and the compression spring is located between the opposite stepped surfaces of the guide shaft and the left chuck.
[0010] An optimized version of the above technical solution is that an arc-shaped claw groove is provided on the surface of the left claw and the right claw, and a pressing rubber is provided on the inner wall of the arc-shaped claw groove.
[0011] An optimized version of the above technical solution is that the eccentric adjustment wheel assembly includes an eccentric wheel rotatably mounted on the top of the bracket via an eccentric shaft, and a handle rod disposed on one side of the eccentric wheel. The connection point between the eccentric shaft and the eccentric wheel is not the center of a circle.
[0012] An optimized version of the above technical solution is that a stop screw is screwed to the side of the upper panel of the bracket, and the stop screw is screwed to its deepest point to contact the eccentric shaft.
[0013] An optimized version of the above technical solution is that the end of the handle is provided with a ball head.
[0014] An optimized version of the above technical solution is that a rubber pad is provided on the lower plate of the bracket, and the rubber pad is located below the assembly hole.
[0015] An optimized version of the above technical solution is that the wrench assembly includes a wrench body and wrench handles symmetrically arranged on both sides of the wrench body, and a matching protrusion that matches the process groove of the pressure ring is provided below the wrench body.
[0016] Compared with existing technologies, the beneficial effects of this utility model are:
[0017] 1. The tool provided by this utility model has a compact structure, is simple and convenient to use, is easy to clamp and remove without damaging the housing, and ensures assembly quality. The one-button adjustment of the eccentric wheel assembly enables rapid adjustment of the clamping distance, significantly shortening the time for fixing and removing the housing. This improves production efficiency. At the same time, the eccentric wheel adjustment mechanism allows the clamping assembly to adapt to conical housings of different sizes, expanding the tool's applicability and reducing the cost of special tools required for multi-specification products.
[0018] 2. The arc-shaped claw groove of the claw design provided by this utility model fits the conical shell shape, and combined with the elastic buffer of the pressing rubber, it avoids the metal claw from directly contacting the shell surface, which significantly reduces the risk of scratches, indentations or deformation. At the same time, the rubber pad at the bottom provides flexible support to prevent damage to the bottom of the shell due to rigid contact.
[0019] 3. The locking screw reinforcement provided by this utility model restricts the position of the eccentric shaft by screwing the locking screw, thereby further ensuring the reliability of the clamping state.
[0020] 4. The wrench assembly provided by this utility model has a matching protrusion at the lower end that precisely fits with the pressure ring process groove, ensuring that the pressure ring is evenly stressed when screwed in, avoiding slippage or misalignment, reducing repeated adjustments, and improving assembly speed.
[0021] In summary, the tool provided by this utility model solves the problems of easy damage, low efficiency, and poor quality consistency in the assembly process of conical thin-walled shells. It combines high efficiency, safety, and economy, while reducing the scrap rate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] In the description of this utility model, unless otherwise stated, "a plurality of" means 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, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] As attached Figure 1 To be continued Figure 4 As shown, the technical solution of this embodiment mainly includes two parts: 1. the clamping part of the housing 17; 2. the tightening part of the pressure ring 18;
[0031] As attached Figures 1 to 3 As shown, 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 set at the left and right ends of the upper panel. An assembly hole 2 is opened on the upper panel of the bracket 1.
[0032] The upper plate of bracket 1 includes an eccentric adjustment wheel assembly and a clamping assembly. The lower plate has waist holes around its perimeter for fixing the entire assembly to the workbench with screws.
[0033] The clamping assembly specifically includes two jaws, a left jaw 6 and a right jaw 3. Arc-shaped jaw grooves are provided on the opposite surfaces of the two jaws. By narrowing and widening the gap between the two arc-shaped jaw grooves, the housing 17 can be clamped and released. Therefore, in order to prevent damage to the housing 17 during the clamping process, a compression rubber 7 is glued to the inner wall of the arc-shaped jaw groove.
[0034] The right claw 3 is located on the right end of the upper panel of the bracket 1. The right claw 3 is fixed from bottom to top with screws. At the same time, a guide shaft 4 is provided on the left end face of the right claw 3. The two guide shafts 4 are located at both ends of the arc-shaped claw groove. The guide shaft 4 is stepped with the left end smaller than the right end. A compression spring 5 is sleeved at the front end of the guide shaft 4.
[0035] A through-hole is provided on the opposite surfaces of the left pawl 6 and the right pawl 3. The sliding hole is smaller at the left end and larger at the right end, forming a stepped shape. The left pawl 6 is inserted into the guide shaft 4 through the sliding hole. The compression spring 5 is located between the guide shaft 4 and the opposite stepped surface of the sliding hole, thereby limiting the compression spring 5 at both ends. It can be compressed, so the left pawl 6 is slidably set relative to the right pawl 3.
[0036] Meanwhile, an eccentric adjusting wheel component is provided on the left side of the left chuck 6. Its specific structure is as follows: the eccentric shaft 8 has threads at both the upper and lower ends, is installed on the upper plate of the bracket 1, and the lower end is locked with a nut and a washer. After the upper end of the eccentric shaft 8 is fitted into the eccentric wheel 9, the nut and washer are installed. 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, which ensures that the eccentric wheel 9 can rotate around the eccentric shaft 8.
[0037] The right side of the eccentric wheel 9 contacts the left side of the left pawl 6. At the same time, the connection point between the eccentric wheel 9 and the eccentric shaft 8 is not the center of the eccentric wheel 9. This causes the rotation of the eccentric wheel 9 to work with the compression spring 5 to change the distance between the left pawl 6 and the right pawl 3.
[0038] A handle rod 10 is screwed to the side of the eccentric wheel 9. For easy handling, a ball head 12 is screwed to the other end of the handle rod 10.
[0039] In order to fix the eccentric shaft 8 and prevent it from rotating, a stop screw 11 is screwed to the side of the upper panel of the bracket 1. The stop screw 11 is screwed to its deepest point and can contact the eccentric shaft 8. Through the screwing of the stop screw 11, the eccentric shaft 8 is tightened, thus fixing the eccentric shaft 8 and preventing it from rotating. This ensures that there will be no loosening during the clamping of the housing 17.
[0040] To prevent damage to the bottom of the housing 17 during processing, a rubber pad 13 is installed on the lower panel of the bracket 1 below the assembly hole 2 to protect the lower end of the housing 17.
[0041] In the above positional relationship, although from left to right they are eccentric wheel 9, left pawl 6 and right pawl 3, the positions can be reversed, and from left to right they are right pawl 3, left pawl 6 and eccentric wheel 9. Therefore, there are no special requirements for the positional relationship, and the positions that meet the above functions are the same as those in this technical solution.
[0042] As attached Figure 3 With appendix Figure 4 As shown, the tightening part of the pressure ring 18 has a main structure of a 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.
[0043] In order to match the pressure ring 18, a matching protrusion 16 is provided on the lower end face of the wrench body 14 to match the process groove of the pressure ring 18. This ensures that the pressure ring 18 is screwed in with uniform force, avoids slippage or misalignment, reduces repeated adjustments, and improves assembly speed.
[0044] As attached Figure 3 As shown, the usage process of this technical solution is as follows:
[0045] Step 1: Place bracket 1 on the workbench and fix bracket 1 with screws;
[0046] Step 2: Place the rubber pad 13 on the upper surface of the lower plate of the bracket 1 and below the mounting hole 2;
[0047] Step 3: Grasp the handle rod 10 and rotate the eccentric wheel 9 so that the left pawl 6 moves to the left under the action of the compression spring 5, thereby increasing the distance between the left pawl 6 and the right pawl 3, and then passing the housing 17 through the left pawl 6 and the right pawl 3, and then through the assembly hole 2, so that the lower end of the housing 17 is placed on the rubber pad 13 on the lower plate of the bracket 1.
[0048] Step 4: Grasp the handle lever 10 again and rotate the eccentric wheel 9, so that the left pawl 6 moves to the right under the action of the eccentric wheel 9, thereby reducing the distance between the left pawl 6 and the right pawl, thus clamping the housing 17. At this time, the compression spring 5 is in a continuously compressed state.
[0049] Step 5: Insert the pressure ring 18 from the top of the housing 17, hold the lever handles 15 on both sides with both hands, so that the matching protrusion 16 is engaged in the process groove of the ring, control the lever handles 15 with both hands, rotate the lever body 14 to complete the screw connection between the housing 17 and the pressure ring 18, thereby completing the assembly.
[0050] Step 6: Repeat the steps in Step 3 to remove the assembled components.
[0051] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
