Description

Technical Field

[0001] This utility model relates to a manual installation device for a pipe clamp of an automotive exhaust system connector, belonging to the field of automotive parts assembly technology. Background Technology

[0002] In the automotive manufacturing industry, the assembly process of exhaust system connecting pipes places stringent requirements on connection sealing and structural stability. Currently, pipe clamp installation is generally performed using integrated automated assembly equipment. This type of equipment achieves automated pressing, positioning, and fastening of pipe clamps through a pre-set mechanical transmission mechanism and control system, significantly improving production line assembly efficiency. However, such automated equipment has the following technical drawbacks:

[0003] 1. The integrated nature of the equipment makes its operation highly dependent on the standardized production environment. When rework is required, it is difficult to carry out local maintenance operations independently outside the production line due to the limited size of the equipment and the requirements of the working space. This results in a high degree of coupling between the rework process and the main production process. When dealing with small-batch rework needs, the energy consumption and equipment depreciation cost amortization ratio of traditional automated equipment are significantly higher than the cost of manual operation, resulting in deterioration of maintenance economy.

[0004] 2. Automated assembly processes require multiple operators to work together to complete tasks such as workpiece loading and unloading, parameter monitoring, and quality inspection. In non-standard maintenance scenarios, this multi-station collaboration mode directly leads to redundant human resources. Summary of the Invention

[0005] To address the problems existing in the background art, this utility model provides a manual installation device for the coupling of automotive exhaust system connectors.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a manual installation device for a connector clamp of an automotive exhaust system, comprising grippers, C-clamps, a contour mold, a fixing plate, a connecting shaft, a connecting rod, a movable block, and a rotating handle; the upper end of the movable block is fixed with a contour mold, the left and right sides of the movable block are symmetrically arranged inclined surfaces, the front and rear sides of the movable block are both provided with fixing plates, the front and rear surfaces of the movable block are both fixed with horizontally arranged connecting shafts, each fixing plate is provided with a vertical groove, and each connecting shaft is slidably arranged in the corresponding vertical groove; each inclined surface is slidably connected to the lower end of the corresponding C-clamp, the two C-clamps are symmetrically arranged, the two C-clamps are hinged to the corresponding ends of the two fixing plates, each connecting shaft is hinged to one end of the corresponding connecting rod, the other end of each connecting rod is hinged to the upper end of the corresponding rotating handle, and grippers are fixed to the relatively inner ends of the upper ends of the two C-clamps.

[0007] Furthermore, the length of the vertical section of each of the C-type clamps can be adjusted.

[0008] Furthermore, each of the C-clamps is equipped with a roller at its lower end, and each roller is rolledly connected to a corresponding inclined plane.

[0009] Furthermore, a spring is installed between the lower end of each of the C-clamps and the upper end of the corresponding rotating handle.

[0010] Furthermore, each of the C-clamps is fitted with an anti-slip pad on its clamping surface.

[0011] Furthermore, the movable block has a vertical groove in the middle, and the lower ends of the two fixed plates are fixedly connected by a fixed shaft, which is slidably disposed in the vertical groove.

[0012] Furthermore, the lower end of each of the rotating handles is detachably and fixedly connected to the corresponding extension rod.

[0013] Furthermore, each of the rotating handles has a gripping part with anti-slip texture.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model adopts a lever-type transmission structure combined with a contour mold. While ensuring the coaxiality of the installation and the pressing force of the sealing surface, it reduces the number of operators required from multiple people to a single person, significantly reducing the manpower intensity of the rework station. At the same time, it can be deployed independently of the automated production line, which is particularly suitable for small-batch rework scenarios, increasing convenience, avoiding the sharing of energy consumption and depreciation costs of traditional equipment, and optimizing the economic indicators of maintenance.

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0019] A manual installation device for a connector clamp of an automotive exhaust system includes a clamp 1, a C-clamp 2, a contour mold 3, a fixing plate 4, a connecting shaft 5, a connecting rod 8, a movable block 9, and a rotating handle 10. The upper end of the movable block 9 is fixed with the contour mold 3. The left and right sides of the movable block 9 are symmetrically arranged and inwardly tapering inclined surfaces, preferably an isosceles trapezoidal structure. Fixing plates 4 are provided on both the front and rear sides of the movable block 9. A horizontally arranged connecting shaft 5 is fixed to both the front and rear surfaces of the movable block 9. Each fixing plate 4 has a through-type connection along its thickness direction. Vertical groove 12, each of the connecting shafts 5 is slidably disposed in the corresponding vertical groove 12; each of the inclined surfaces is slidably connected to the lower end of the corresponding C-type clamp 2, the two C-type clamps 2 are symmetrically arranged, the corresponding ends of the two C-type clamps 2 and the two fixed plates 4 are hinged by corresponding pins, each connecting shaft 5 is hinged to one end of the corresponding connecting rod 8, and the other end of each connecting rod 8 is hinged to the upper end of the corresponding rotating handle 10 by corresponding pins, and the relative inner ends of the upper ends of the two C-type clamps 2 are fixed with grippers 1.

[0020] Furthermore, the length of the vertical section of each of the C-type clamps 2 can be adjusted. For example, the vertical section includes two sections that are detachably and fixedly connected by bolts. By changing the length of the vertical section, it can be adapted to the installation requirements of different products.

[0021] Furthermore, each of the C-type clamps 2 is rotatably mounted with a roller 6 at its lower end. Each roller 6 is connected to the corresponding inclined plane in a rolling manner, which changes sliding into rolling, reduces frictional resistance, and avoids wear and tear during use.

[0022] Furthermore, a spring 7 is installed between the lower end of each C-clamp 2 and the upper end of the corresponding rotating handle 10 to facilitate the quick reset of the C-clamp 2.

[0023] Furthermore, each of the C-clamps 2 is fitted with an anti-slip pad, such as rubber or silicone, on its clamping surface to increase friction with the pipe clamp, prevent the pipe clamp from slipping during installation, and improve installation accuracy.

[0024] Furthermore, the movable block 9 has a vertical groove 13 in the middle, and the lower ends of the two fixed plates 4 are fixedly connected by a fixed shaft 11. The fixed shaft 11 is slidably arranged in the vertical groove 13. The stability of the device is improved by using the principle that the connecting shaft 5 and the fixed shaft 11 determine a straight line.

[0025] Furthermore, the lower end of each of the rotating handles 10 is detachably and fixedly connected to the corresponding extension rod by bolts, thereby lengthening the rotating handle 10 to reduce torque and increase efficiency.

[0026] Furthermore, each of the rotating handles 10 has an anti-slip texture on its grip portion, which is an annular convex ridge structure used to improve grip stability during manual operation.

[0027] When using this invention to clamp the pipe clamp, rotating the two rotating handles 10 inwards pushes the connecting shaft 5 via the connecting rod 8, causing the movable block 9 to move upwards. Since the left and right sides of the movable block 9 are symmetrically arranged and have inwardly contracting slopes, when the movable block 9 moves upwards, the two C-shaped clamps 2 open. Then, the conforming mold 3 is aligned with the pipe fitting, the force on the two rotating handles 10 is released, and under the action of the spring 7, the two C-shaped clamps 2 return to their original position, thus achieving the clamping of the pipe clamp.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
