Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carburetor equipment, in particular to a positioning fixture for processing a carburetor float. Background Art
[0002] As a precision mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to realize the atomization of gasoline, which can convert liquid fuel (such as gasoline) into combustible gas so that it can enter the internal combustion engine for combustion. Its important role in the engine can be called the "heart" of the engine. The existing carburetor usually consists of a float chamber, an intake pipe and an oil intake pipe. By transporting air and fuel to the mixing chamber for mixing, the air and fuel are supplied to the internal combustion engine for combustion, so that the engine can operate normally.
[0003] Based on the above, a carburetor float is installed in the float chamber of the carburetor. The carburetor float is mainly used to control the oil level in the carburetor, and the accuracy of the carburetor float surface will directly affect the precise control of the oil level in the carburetor. After the existing carburetor float is produced, the float needs to be trimmed to make the carburetor float have more accurate accuracy, but the float needs to be fixed when the float is trimmed. The existing fixing fixture for the carburetor float usually uses a cylinder to drive the clamping plate to press down to fix the float, but this method is not only unstable for the fixation of the float, but the clamping plate will cause wear to the float when it is pressed down.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Example:
[0030] See also Figure 1-Figure 7 A positioning fixture for processing a carburetor float, the structure of which includes a base plate 1, a power part 2, a clamping plate part 3 and a cleaning part 4. The power part 2 is installed on the base plate 1, and the two ends of the power part 2 are slidably matched with the clamping plate parts 3, and the cleaning parts 4 are symmetrically installed on both sides of the base plate 1.
[0031] In this embodiment, a positioning groove 11 is provided on the bottom plate 1. The shape of the positioning groove 11 is the same as that of the float 5, and the float 5 can be installed and positioned. Fixed blocks 12 are installed on both sides of the bottom plate 1. The fixed blocks 12 can be fixed to the cleaning piece 4 through arc-shaped grooves.
[0032] In this embodiment, the power part 2 includes a dual-axis motor 21, a left screw rod 22 and a right screw rod 23. The dual-axis motor 21 is fixed on the base plate 1. The output shafts at both ends of the dual-axis motor 21 are respectively connected to the left screw rod 22 and the right screw rod 23. The thread directions on the left screw rod 22 and the right screw rod 23 are opposite and symmetrical to each other and both slide with the clamping plate part 3, so that when the dual-axis motor 21 drives the left screw rod 22 and the right screw rod 23 to rotate, it will drive the two groups of clamping plate parts 3 to move relative or in the same direction at the same time under the guidance of the screw guide.
[0033] In this embodiment, the clamping member 3 includes a moving seat 31, a connecting rod 32, a clamping claw 33 and a rubber pad 34. The moving seat 31 is slidably matched with the left screw rod 22 and the right screw rod 23 through a guide member. A connecting rod 32 is fixed to one side of the moving seat 31, and a clamping claw 33 is connected to one side of the connecting rod 32. A rubber pad 34 is installed on the inner side of the clamping claw 33. The rubber pad 34 can prevent the clamping claw 33 from causing damage to the float 5 when clamping and fixing the float 5, and the side of the rubber pad 34 close to the float 5 is a raised friction surface, which can increase the friction with the float 5 and thereby increase the degree of fixation of the float 5.
[0034] In this embodiment, the cleaning component 4 includes an air pump 41, a piston rod 42, a first air pipe 43 and a second air pipe 44. The air pump 41 is located on the fixed block 12. One end of the air pump 41 is slidably matched with the piston rod 42. The other end of the piston rod 42 is connected to the connecting rod 32, and the piston rod 42 can be driven to move together to perform an inflating movement through the movement of the connecting rod 32. The other end of the air pump 41 is rotatably matched with the first air pipe 43 and the second air pipe 44. The first air pipe 43 and the second air pipe 44 can rotate on the air pump 41 to adjust the blowing direction.
[0035] Working principle: when the carburetor float that has been produced needs to be trimmed, the float 5 is placed in the positioning groove 11 of the bottom plate 1, and the positioning groove 11 can install and position the float 5, and then the double-axis motor 21 is driven to rotate forward, and the left screw rod 22 and the right screw rod 23 at both ends are driven to rotate by the double-axis motor 21. With the help of the guiding effect of the guide member inside the moving seat 31, the rotation of the left screw rod 22 and the right screw rod 23 will drive the moving seat 31 thereon to slide toward each other, thereby driving the two sets of clamping claws 33 to approach each other, so as to clamp and position the float 5 in the positioning groove 11, so that the float 5 will not move in the positioning groove 11 when trimming;
[0036] Since one side of the connecting rod 32 is connected to the piston rod 42 on the cleaning piece 4, when the jaws 33 move to clamp the float 5, the piston rod 42 will be driven to move and extend together. Then, when the float 5 completes the trimming work, the dual-axis motor 21 drives the screw rods at both ends to move and reset the jaws 33. The connecting rod 32 will drive the piston rod 42 to reset together and move the internal piston in the air pump 41 to generate gas by pumping. The generated gas will be blown out from the first air pipe 43 and the second air pipe 44 at the other end to blow away and clean the debris remaining on the float 5 after the trimming is completed.
