Description

Technical Field

[0001] This utility model relates to the field of carburetor throat processing technology, and in particular to a processing and shaping mechanism for carburetor throats. Background Technology

[0002] The carburetor throat is a key component of the carburetor, serving as the passageway for air and fuel mixing. Its shape is typically designed to be narrow in the middle and relatively wide at both ends, similar to a venturi tube. This unique shape alters the airflow velocity through the throat, significantly impacting fuel intake and mixing.

[0003] During use, a vacuum forming machine creates a negative pressure environment by extracting internal air. During the carburetor throat forming process, the throat blank is placed in the mold. When the vacuum forming machine is working, the throat blank is tightly attached to the mold wall under the action of external atmospheric pressure. This pressure difference ensures that the throat blank is formed according to the precise shape of the mold, effectively improving the accuracy of the throat shape.

[0004] Before processing, multiple sets of molds need to be installed in a vacuum forming machine. During installation, they are fixed by tightening the corresponding bolts or screws. When there are many molds, the labor cost of manually tightening the screws will increase. Manually installing multiple sets of molds by tightening screws is also time-consuming and laborious. In addition, some screw holes are hidden and the operating space is narrow. Operators often need to bend over, turn to the side, or even lie on the edge of the equipment to align the connectors with the holes in an awkward posture. The overall installation is quite troublesome. To solve the above problems, a processing and forming mechanism for carburetor throat pipes is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a processing and shaping mechanism for carburetor throat pipes, which aims to improve the problem of time-consuming and labor-intensive installation of multiple sets of molds by screwing screws in the prior art.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a processing and shaping mechanism for a carburetor hose, comprising a housing 1, which is a vacuum shaping box for processing and shaping the carburetor hose (this is prior art and will not be explained in detail here). A protective door 2 is rotatably connected to the front end of the housing 1, and the protective door 2 can be closed or opened as needed. A fixing mechanism is provided at the inner rear end of the housing 1; this fixing mechanism can then fix multiple sets of molds. The fixing mechanism includes a positioning plate 4, and a support plate 3 is rotatably connected to the bottom end of the inner wall of the positioning plate 4. The support plate 3 can support the mold. A positioning element is provided on the inner wall of the support plate 3, which can then fix the support plate 3 in a horizontal state. A fixing column 5 is fixedly connected to the outer wall of the positioning plate 4, and a movable plate 9 is slidably connected to the outer wall of the fixing column 5. Two sets of fixing columns 5 are provided, and the movable plate 9 is slidably connected to the outer wall of the fixing column 5. The movable plate 9 serves as a guide, allowing it to move only laterally. The positioning plate 4 is fixedly connected to a limiting plate 11 on the side near the fixed column 5. A gear 6 is rotatably connected to the inner wall of the top of the limiting plate 11. The limiting plate 11 provides support for the fixed column 5. Two sets of movable plates 9 are provided, located on the front and rear sides of the gear 6 respectively. The gear 6 drives the two sets of movable plates 9 to move laterally. A fixing clamp 10 is fixedly connected to the outer wall of the front movable plate 9, and the two move along the same trajectory. A sliding clamp 8 is slidably connected to the outer wall of the rear movable plate 9. The movement of the movable plate 9 drives the sliding clamp 8 to move. A limiting mechanism is provided at the right end of the sliding clamp 8, which limits and fixes the sliding clamp 8. A rack 7 is fixedly connected to the side of the front and rear movable plates 9 near the gear 6. The rotation of the gear 6 drives the rack 7 to move.

[0034] Reference Figures 2-4The positioning component includes a movable plate 12, the outer wall of which is slidably connected to the inner wall of the support plate 3. The movable plate 12 can move laterally. The inner wall of the gear 6 is threaded with a bolt 13, the bottom end of which is threadedly connected to the inner wall of the limiting plate 11. The bolt 13 can fix the gear 6 and prevent it from rotating. The outer wall of the gear 6 meshes with the outer tooth surface of the rack 7. The rear end of the positioning plate 4 is fixedly connected to the inner rear end of the housing 1. The outer wall of the movable plate 12 is slidably connected to the inner side wall of the bottom end of the positioning plate 4. A through guide groove is opened at the bottom end of the positioning plate 4 to support and position the movable plate 12.

[0035] Reference Figures 3-5 The limiting mechanism includes a fixed block 14, the left end of which is fixedly connected to the right end of the movable clamp 8. The two move along the same trajectory. The inner wall of the fixed block 14 is elastically connected to a positioning pin 15 via a connecting spring 16. The positioning pin 15 can limit and fix the fixed block 14. One end of the connecting spring 16 is fixedly connected to the inner wall of the fixed block 14, and the other end is fixedly connected to the outer wall of the positioning pin 15. The outer wall of the positioning pin 15 passes through and slides on the inner wall of the fixed block 14. The elasticity of the connecting spring 16 enables the positioning pin 15 to have reset and limiting functions. The top of the front movable plate 9 has an insertion hole, and the bottom end of the positioning pin 15 is inserted into the inner wall of the insertion hole. The insertion hole can adjust the position of the movable clamp 8 to use molds of different sizes.

[0036] Working principle: When personnel need to clamp and fix multiple sets of molds, first adjust the support plate 3 to a horizontal state, so that the moving plate 12 contacts and is positioned with the positioning plate 4. Then, place the relevant molds between the fixed clamp 10 and the moving clamp 8. After placement, release the limit of the bolt 13. At this time, the gear 6 can be rotated. When the gear 6 rotates, the rear moving plate 9 moves to the right and the front moving plate 9 moves to the left, so that the moving clamp 8 and the fixed clamp 10 come together to clamp and fix the molds simultaneously. After fixing, move the moving plate 12 forward to release the contact between the moving plate 12 and the positioning plate 4, and then flip the support plate 3 downward to make it vertical. Then, the housing 1 can be started to position the carburetor hose.

[0037] When multiple sets of molds of different models need to be fixed, the positioning pin 15 is moved upward to release the positioning pin 15 from the limit of the front movable plate 9, and then the moving clamp 8 can be moved laterally to adapt to different models of molds, thereby enhancing the overall practicality.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
