Description

Technical Field

[0001] The utility model relates to the technical field of carburetor processing equipment, in particular to a processing device for a carburetor throttle shaft. Background Art

[0002] The carburetor, as the indispensable "heart" of the engine, has the outstanding function of using the vacuum effect generated when the engine is running to accurately mix gasoline and air and use the intake power to achieve fine atomization of gasoline. This process is not only the cornerstone of the efficient operation of the engine, but also the source of its surging power. In the manufacturing process of the throttle shaft, a key component of the carburetor, the processing of the long keyway is crucial. This detail is not only directly related to the throttle's fine control of air flow, but also has a profound impact on the engine's speed stability and overall performance. Therefore, extremely high requirements are placed on the processing accuracy of the throttle shaft, and any slight deviation may have a significant impact on the working efficiency of the engine.

[0003] However, the processing devices in the prior art are unable to cope with this high-precision requirement. The first is the lack of a stable and flexible fixing and adjustment mechanism, which makes it difficult for the throttle shaft to maintain the optimal posture during the processing, thus limiting the improvement of processing accuracy and efficiency.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The processing device of the carburetor throttle shaft according to the embodiment of the utility model will be described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the processing device for the carburetor throttle shaft according to the embodiment of the utility model may include a base plate 10 , a side plate 20 and a top plate 30 .

[0024] There are two side panels 20, which are symmetrically arranged at both ends of the base plate 10, and both ends of the top plate 30 are respectively connected to the ends of the two side panels 20 away from the base plate 10, so that the base plate 10, the side panels 20 and the top plate 30 are combined into a rectangular frame. It should be noted that the base plate 10, the side panels 20 and the top plate 30 are made of hard metal, such as metal iron.

[0025] The first driving component 11 is installed on the top surface of the base plate 10, and a lower limit plate 40 is installed on the output shaft of the first driving component 11. The output shaft of the first driving component 11 is vertically upward and is used to drive the lower limit plate 40 to rotate. The top surface of the lower limit plate 40 is provided with a limit groove 41. It should be noted that the material of the lower limit plate 40 is hard metal, such as metal iron.

[0026] It should be noted that the first driving component 11 drives the lower limit plate 40 to rotate, and may be a rotary motor.

[0027] A vertical telescopic component 31 is installed on the bottom surface of the top plate 30, and the vertical telescopic component 31 is located directly above the first driving component 11. The output end of the vertical telescopic component 31 is rotatably connected to a docking plate 32, and the docking plate 32 corresponds to the lower limit plate 40. The lower end of the vertical telescopic component 31 is a telescopic end. The throttle shaft is arranged between the limit groove 41 and the docking plate 32 during processing, and a corresponding punching component is provided on one side of the base plate 10. It should be noted that a docking groove corresponding to the limit groove 41 can be opened on the bottom surface of the docking plate 32 (not shown in the figure).

[0028] Specifically, the bottom end of the vertical telescopic component 31 may be connected to the docking plate 32 via a rotating shaft (not shown in the figure).

[0029] In one embodiment of the present invention, Figure 1 As shown, the punching assembly includes a screw rod 50 and a mounting block 60, a second driving component 33 is mounted on the top surface of one end of the side plate 20 away from the vertical telescopic component 31, the top end of the screw rod 50 passes through the top plate 30 and is connected to the driving end of the second driving component 33, the bottom end of the screw rod 50 is rotatably connected to the base plate 10, and the screw rod 50 is vertically arranged. It should be noted that the bottom end of the screw rod 50 can be rotatably connected to the base plate 10 through a bearing.

[0030] It should be noted that the second driving component 33 drives the screw 50 to rotate, and may be a rotary motor.

[0031] The mounting block 60 is located between the base plate 10 and the top plate 30, the screw rod 50 passes through the mounting block 60, and the screw rod 50 is engaged with the mounting block 60, so that when the screw rod 50 rotates, it can drive the mounting block 60 to move up and down, and the end of the mounting block 60 away from the vertical telescopic part 31 slides and abuts against the side plate 20, and the end of the mounting block 60 close to the vertical telescopic part 31 is installed with a horizontal telescopic part 61, and the end of the horizontal telescopic part 61 close to the vertical telescopic part 31 is installed with a puncher 62.

[0032] It should be noted that the vertical telescopic component 31 and the horizontal telescopic component 61 are automatic telescopic devices, such as telescopic cylinders.

[0033] Specifically, in the actual operation, the relevant personnel place the throttle shaft between the limit groove 41 and the docking plate 32, and adjust the height of the docking plate 32 by the vertical telescopic component 31 so that the throttle shaft is firmly clamped. The first driving component 11 is started, and the lower limit plate 40 is driven to rotate by the first driving component 11, so that the throttle shaft is rotated between the limit groove 41 and the docking plate 32 to the required processing angle. The second driving component 33 is started to drive the screw 50 to rotate. Since the screw 50 is engaged with the mounting block 60, the rotation of the screw 50 will drive the mounting block 60 to move up and down. At the same time, the mounting block 60 slides along the side plate 20 to ensure the stability of its movement. By adjusting the position of the mounting block 60, the height of the punch 62 can be changed. Under the push of the horizontal telescopic component 61, the punch 62 moves toward the throttle shaft to a predetermined position, and then performs the punching operation. After the punching is completed, the horizontal telescopic component 61 withdraws the punch 62 to the initial position.

[0034] The precise limit and rotation mechanism ensures the stability and accuracy of the throttle shaft during processing, thereby improving the processing accuracy. The cooperation of the vertical telescopic component 31 and the horizontal telescopic component 61 enables the punching machine 62 to move freely to meet different processing requirements.

[0035] In one embodiment of the present invention, Figure 2 As shown, an upper limit plate 80 is arranged above the lower limit plate 40, a support rod 70 is installed between the upper limit plate 80 and the lower limit plate 40, a limit opening 81 corresponding to the limit groove 41 is opened on the upper limit plate 80, and the bottom end of the throttle shaft passes through the limit opening 81 and abuts against the limit groove 41. It should be noted that the support rod 70 is vertically connected between the upper limit plate 80 and the lower limit plate 40, and the distance between the two can be controlled, and the support rod 70 and the throttle shaft will not touch each other during the processing.

[0036] It should be noted that if Figure 2 and Figure 3 As shown, the support rod 70 may be an automatic telescopic device, such as an electric telescopic rod, which can control the distance between the lower limit plate 40 and the upper limit plate 80.

[0037] It should be noted that the upper limit plate 80 in this embodiment has various specifications. The limit openings 81 on upper limit plates 80 of different specifications have different sizes. Different upper limit plates 80 are selected according to the size specifications of the throttle shaft to be processed, which will not be described in detail here.

[0038] Specifically, in the actual operation, the relevant personnel install a suitable upper limit plate 80 according to the size of the throttle shaft, and adjust the distance between the lower limit plate 40 and the upper limit plate 80 by controlling the extension and contraction of the support rod 70, so that the limit opening 81 and the limit groove 41 can accurately correspond to and clamp the throttle shaft. The bottom end of the throttle shaft passes through the limit opening 81 and contacts the limit groove 41. At this time, the throttle shaft is clamped by the upper limit plate 80 and the lower limit plate 40.

[0039] The double clamping mechanism of the upper limit plate 80 and the lower limit plate 40 reduces the vibration and deviation of the throttle shaft during processing, thereby improving the processing accuracy. The automatic telescopic function of the support rod 70 enables the device to adapt to throttle shafts of different lengths, improving the versatility and flexibility of the device.

[0040] Further, in one embodiment of the present invention, Figure 4 and Figure 5 As shown, the upper limit plate 80 is hollow inside, and the side wall of the limiting opening 81 is connected to the inside of the upper limit plate 80. A plurality of arc-shaped spring pieces 82 are provided inside the upper limit plate 80. The plurality of arc-shaped spring pieces 82 are arranged in a ring array. One end of the arc-shaped spring piece 82 is hinged on the inner wall of the upper limit plate 80, and the other end is bent inward and slides against the inner wall of the upper limit plate 80. The arc surface of the arc-shaped spring piece 82 faces the limiting opening 81. At this time, the middle positions of the plurality of arc-shaped spring pieces 82 extend out of the limiting opening 81 and are in contact with each other.

[0041] In one embodiment of the present invention, Figure 5 As shown, the material of the arc-shaped spring piece 82 can be spring steel.

[0042] Specifically, the number of the arc-shaped spring pieces 82 is 3 to 5, which can be selected according to actual usage and is not limited here.

[0043] It should be noted that the upper limit plate 80 in this embodiment can be of fixed specifications, and can be adapted to throttle shafts of different sizes and specifications through the arc-shaped spring piece 82 .

[0044] Specifically, during the actual operation, the relevant personnel pass the throttle shaft through the limit opening 81. As the throttle shaft enters the limit opening 81, the arc-shaped spring piece 82 is squeezed and opens outward until the top of the throttle shaft completely passes through the limit opening 81. At this time, the middle position of the arc-shaped spring piece 82 is in contact with the throttle shaft, forming a stable clamp for the throttle shaft. It can adaptively clamp throttle shafts of different sizes without replacing upper limit plates 80 of different specifications, thereby improving work efficiency and the versatility of equipment and reducing costs.

[0045] In summary, the carburetor throttle shaft processing device of the embodiment of the utility model can not only firmly fix the carburetor throttle shaft, but also easily adjust its processing angle, thereby improving the processing efficiency of the carburetor throttle shaft.
