[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figure 1-Figure 7The assembly auxiliary device for carburetor production shown in the figure comprises a base 1, a first screw drive mechanism 2 and a second screw drive mechanism 4, wherein the first screw drive mechanism 2 is provided with two groups and symmetrically mounted on the upper surface of the base 1, a stand 3 is provided on the outer side of each of the first screw drive mechanisms 2, the second screw drive mechanism 4 is jointly arranged between the two stands 3, a slide 5 is provided on the outer side of the second screw drive mechanism 4, a welding mechanism is provided on the inner side of the slide 5, a storage platform 8 is provided on the upper surface of the base 1 and at one end away from the second screw drive mechanism 4, a round table 10 is fixedly provided on the upper surface of the storage platform 8, a positioning mechanism is provided on the outer side of the round table 10 and at equal distances along the circumferential direction, and a supporting rotation mechanism is provided in the middle of the inner side of the round table 10;

[0028] Reference Manual Attached Figure 1 and Figure 2 It can be seen that the first screw drive mechanism 2 and the second screw drive mechanism 4 are composed of a screw group, a slide rail group, a servo motor group and the like, which are existing drive mechanisms and will not be described in detail here.

[0029] The welding mechanism includes a lifting mechanism 6 disposed above the inner side of the slide 5, and a welding gun 7 is disposed at the telescopic end of the lifting mechanism 6;

[0030] Reference Manual Attached Figure 1 and Figure 2 It can be seen that, driven by the lifting mechanism 6, the up and down movement of the welding gun 7 can be automatically controlled to cooperate with workers in welding and assembly.

[0031] The positioning mechanism includes a strip frame 11 fixedly arranged on the outside of the truncated table 10, a round seat 17 is arranged at one end of the strip frame 11 away from the truncated table 10, a vertical rod 19 is fixedly connected to the upper surface of the round seat 17, and sliding elastic members are arranged at both ends of the inner side of the vertical rod 19, and the sliding elastic member includes a slide bar 18 slidably inserted inside the vertical rod 19, a spring 21 is arranged on the outer side of one end of the slide bar 18 away from the vertical rod 19, a U-shaped frame 20 is arranged at the end of the slide bar 18, and a rolling member is arranged inside the U-shaped frame 20;

[0032] Reference Manual Attached Figure 3 , Figure 4 and Figure 5 It can be seen that the strip frame 11 and the round seat 17 can set up the vertical rod 19 on one side of the round table 10, in order to assemble the sliding rod 18 that can slide elastically inside. When the rolling part is squeezed, it will squeeze the spring 21, causing the sliding rod 18 to automatically expand and contract horizontally inside the vertical rod 19.

[0033] The rolling member includes an elastic rod 23 inserted into the inner side of the U-shaped frame 20, and a plurality of polygonal sleeves 22 are rotatably mounted on the outer side of the elastic rod 23;

[0034] Reference Manual Attached Figure 5It can be seen that after the polygonal sleeve 22 is correspondingly squeezed, the elastic rod 23 can be squeezed and deformed by the polygonal sleeve 22. The different sides of the polygonal sleeve 22 can also fit correspondingly with the outer surface of the carburetor, thereby satisfying the positioning of special workpieces. Under the dual elastic pressure of the elastic rod 23 and the spring 21, when assembling the carburetor, it can be pressed against the outer surface of the carburetor in multiple directions. Each surface of the polygonal sleeve 22 is provided with an anti-slip pad.

[0035] The supporting rotation mechanism includes a tray 35 rotatably arranged in the middle of the inner side of the round table 10, a motor 16 is arranged at the bottom of the tray 35, and the motor 16 is located inside the storage table 8. Telescopic sleeves 27 are arranged at both ends of the inner side of the tray 35, and a telescopic rod 26 is slidably installed inside the telescopic sleeve 27. A plurality of positioning holes 30 are opened on the upper surface of the telescopic rod 26. A clamping rod 25 is vertically arranged on the inner side of one end of the telescopic rod 26 away from the telescopic sleeve 27. A brush roller 24 is rotatably sleeved on the outer side of the clamping rod 25. A fixing pin 28 is inserted into the inner side of the telescopic sleeve 27, and the lower end of the fixing pin 28 extends to the inner side of one of the positioning holes 30.

[0036] Reference Manual Attached Figure 4 , Figure 5 and Figure 6 It can be seen that the motor 16 can drive the upper tray 35 to rotate, so as to drive the brush roller 24 to rotate on the outer surface of the multiple polygonal sleeves 22 in the later stage, so as to make the polygonal sleeves 22 fit better when clamping the carburetor. The sliding cooperation of the telescopic rod 26 and the telescopic sleeve 27 can make the brush roller 24 close to the round table 10, thereby achieving the purpose of cleaning.

[0037] Support rods 13 are fixedly connected to the upper surface of the storage table 8 and near the edges on both sides. A fixing seat 9 is arranged above the outer sides of the two support rods 13. A material swinging table 14 is arranged inside the fixing seat 9. A clamping seat 15 is arranged at one end of the material swinging table 14 away from the fixing seat 9. The clamping seat 15 is movably clamped with the brush roller 24.

[0038] Reference Manual Attached Figure 3 and Figure 4 It can be seen that the material table 14 can be used to place assembled parts, which can facilitate the staff to take the parts. In this way, the assembly efficiency can be improved. An arc groove is provided inside the base 15, which can facilitate the clamping of the brush roller 24, so that the brush roller 24 can be located away from the vertical rod 19 to assist in positioning the carburetor.

[0039] The two vertical rods 19 are slidably mounted with clamping rods 29 on their outer sides, and the inner sides of the ends of the two clamping rods 29 that are close to each other are connected to the display mirror 12 through a rotating shaft 34. The ends of the two clamping rods 29 that are away from each other are fixedly mounted with connecting rods 31 on their outer sides, and the ends of the two connecting rods 31 that are away from the clamping rods 29 are both provided with cylinders 33, and the cylinders 33 are connected to the vertical rods 19 through a cross bar 32 that is fixedly mounted on the outer sides.

[0040] Reference Manual Attached Figure 7 It can be seen that the cylinder 33 can drive the connecting rod 31 to automatically rise and fall, so as to facilitate the adjustment of the height of the display mirror 12 so that the magnified welding points can be observed when the carburetor is assembled.

[0041] Working principle: the carburetor housing can be placed between multiple U-shaped frames 20. Due to the special shape of the carburetor itself, the multiple polygonal sleeves 22 at the U-shaped frame 20 can be sectionally attached to the outer surface of the carburetor. The polygonal sleeve 22 can stably clamp the carburetor housing on the outer surface of the tray 35 through the extrusion of the elastic rod 23 and the auxiliary elastic pressing of the spring 21, and multiple brush rollers 24 can also be at the interval separated from the vertical rod 19. Through the sliding cooperation of the telescopic sleeve 27 and the telescopic rod 26, the outer surface of the brush roller 24 is prompted to contact the outer surface of the carburetor. As a result, according to the shape of the carburetor itself, it can be flexibly clamped during assembly and welding, and the brush roller 24 can also be pushed by the telescopic rod 26 to one side of the truncated table 10. As a result, the polygonal sleeve 22 can be cleaned under the drive of the motor 16, and during the rotation process, the polygonal sleeve 22 can automatically change its surface, thereby reducing the extrusion loss of the anti-slip pad of the polygonal sleeve 22.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
