[0002] The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the working engine. As a precision mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to achieve gasoline atomization. Its important role in the engine can be called the "heart" of the engine. Its complete device should include a starting device, an idle device, a medium load device, a full load device, and an acceleration device. The carburetor will automatically proportion the corresponding concentration and output the corresponding amount of mixed gas according to the different working state requirements of the engine. In order to make the mixed gas mixed more evenly, the carburetor also has the effect of atomizing the fuel for the normal operation of the machine.

[0003] In order to ensure that the carburetor can be assembled accurately, workers often need to use fixing clamps during operation. Most of the existing carburetor assembly shell fixing clamps use two clamp plates to clamp and fix the carburetor from both sides.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4A carburetor assembly housing fixing fixture comprises a workbench 1 with multiple bases, a tool drawer is provided on the workbench 1, a pull ring is provided on the work drawer, and the worker can put the tools used in the work into the drawer for standby use. Two clamping assemblies are provided on the workbench 1, and the clamping assembly comprises a supporting pad 2 arranged on a side wall of the workbench 1 away from the base, and the supporting pad 2 is connected with an adjustment block 3 through a lifting assembly, and the lifting assembly comprises a lifting groove arranged on the supporting pad 2, and a lifting slide plate 14 is fixedly connected in the lifting groove, and a lifting slider 15 is slidably connected to the lifting slide plate 14, and a lifting pad 16 is fixedly connected to the lifting slider 15, and the lifting pad 16 and the adjustment block 3 are fixedly connected, so that the lifting pad 16 can drive the adjustment block 3 to rise or fall together;

[0023] A working rack 17 is provided on the lifting slide block 15, and a working shaft 18 is rotatably connected in the lifting groove. One end of the working shaft 18 close to the working rack 17 is fixedly connected to a working gear 19, and the working gear 19 is meshed with the working rack 17, so that when the working shaft 18 is rotated, the lifting slide block 15 can be driven to slide along the lifting slide plate 14 through gear transmission. A working groove 4 is provided on the adjustment block 3, and a working screw 5 is rotatably connected in the working groove 4. One end of the working screw 5 rotates and penetrates the adjustment block 3. The threads on both sides of the working screw 5 are in opposite directions. A rotating handle is provided on the working screw 5, and the rotating handle is set in a disc shape. The rotating handle and the working screw 5 are matched to be more convenient for the staff to rotate the working screw 5. Two working slide blocks 6 are threadedly connected to the working screw 5, and the two working slide blocks 6 are matched with the working screw 5, so that when the working screw 5 is rotated, the two working slide blocks 6 can be driven to move toward each other;

[0024] A working slide bar 7 is also fixedly connected in the working groove 4. Two working slide blocks 6 are slidably connected to the working slide bar 7. The working slide bar 7 runs through the two working slide blocks 6, thereby limiting the two working slide blocks 6 so that the two working slide blocks 6 can only slide along the working screw 5. One end of the two working slide blocks 6 away from the working screw 5 is fixedly connected with a clamping block 8. The two clamping blocks 8 are both arranged in an arc shape, so that the carburetor can be clamped and fixed in multiple directions of freedom, which greatly improves the fixing effect of the carburetor. A working spring 9 is arranged between the two clamping blocks 8, and multiple clamping blocks 8 are provided with protective pads. The multiple protective pads are respectively arranged in conjunction with the inner side walls of the multiple clamping blocks 8 to avoid damage to the carburetor housing.

[0025] The workbench 1 is also provided with a transverse adjustment component, which includes a working chamber 10 arranged in the workbench 1, a positioning plate is fixedly connected in the working chamber 10, and an auxiliary screw 11 is rotatably connected to the positioning plate, one end of the auxiliary screw 11 rotates and penetrates the workbench 1, an adjusting block 12 is threadedly connected to the auxiliary screw 11, and an auxiliary slide bar 13 is also fixedly connected to the positioning plate, the auxiliary slide bar 13 slides and penetrates the adjusting block 12, thereby limiting the adjusting block 12 so that the adjusting block 12 will only slide along the direction of the auxiliary screw 11, a working slide is provided on the workbench 1, and the working slide and the adjusting block 12 are slidably connected, and one end of the adjusting block 12 away from the auxiliary screw 11 is fixedly connected to one of the supporting pads 2, thereby ensuring that the adjusting block 12 can slide normally.

[0026] During the use of the utility model, the staff first preliminarily rotates the working screw 5 according to the size of the carburetor. Due to the characteristics of the threaded connection, the two working slide blocks 6 will move toward each other under the limiting action of the working slide bar 7, thereby driving the two clamping blocks 8 to move together, thereby adjusting the distance between the two clamping blocks 8. At this time, the staff places the carburetor between the two clamping blocks 8 and rotates the working screw 5 again for fine adjustment. When the two left clamping blocks 8 jointly form a preliminary fixation on the carburetor, the staff can stop rotating the working screw 5 and rotate the auxiliary screw 11 according to the lateral width of the carburetor. Due to the characteristics of the threaded connection, the adjusting slide block 12 will slide along the direction of the auxiliary screw 11 under the limiting action of the auxiliary slide bar 13, thereby driving a supporting pad block 2 fixedly connected thereto to move together, so that the other two clamping blocks 8 are also close to the carburetor;

[0027] At this time, the staff will rotate the working screw 5 according to the shape of the corresponding side of the carburetor, and then fix the other side of the carburetor. During the assembly of the carburetor, when the carburetor needs to be lifted, the staff only needs to rotate the two working shafts 18 to rotate the working gear 19 fixedly connected to it. Due to the characteristics of gear meshing, with the cooperation of the working rack 17, the lifting slider 15 will slide upward along the lifting slide plate 14, and then drive the adjustment block 3 to be lifted through the lifting pad 16, so that the height of the fixed carburetor can be adjusted, which is convenient for the staff to carry out related assembly work.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
