Description

Technical Field

[0001] The invention relates to the field of chainsaw carburetor processing equipment, and in particular to chainsaw carburetor body processing equipment. Background Art

[0002] The chainsaw carburetor, also often referred to as the "vaporizer", is a key device in the chainsaw that is responsible for mixing gasoline and air in a certain proportion and delivering them into the engine combustion chamber in a mist form. Specifically, when the chainsaw is started, the carburetor begins to work, and through specific mechanical structures, such as oil-resistant rubber one-way valves, oil pump diaphragms, etc., the carburetor draws gasoline from the fuel tank and mixes it with the air entering through the air intake. This process is precisely controlled by adjusting devices such as the idle screw and high-speed screw to ensure that the concentration and proportion of the mixture are adapted to the current working state of the engine. The mixed atomized gasoline is then delivered to the engine combustion chamber to provide power for the operation of the chainsaw.

[0003] The carburetor body needs to go through a drilling process during the production process to form various functional small holes. These small holes play a vital role in the carburetor, such as adjusting the mixture ratio of air and fuel to ensure the normal operation of the engine. Specifically, the small holes in the carburetor, such as the throat measuring holes and nozzles, are all processed through the drilling process. The diameter and position of these holes are precisely designed to ensure that the fuel and air can be mixed in a predetermined ratio and burn inside the engine to generate power.

[0004] At present, in some semi-automated carburetor production workshops, the drilling process of the carburetor body still needs manual participation. That is, during the drilling process of the carburetor body, the carburetor body needs to be placed on the drilling equipment manually and fixed in the drilling position. After the drilling is completed, it is removed manually, and this cycle is repeated. The processing efficiency is affected by the workers' proficiency, the operation process is cumbersome, and the production efficiency is reduced.

[0037] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] Example: Please refer to Figures 1 to 7 A chain saw carburetor body processing equipment is used to improve the drilling efficiency of the chain saw carburetor body 100. Specifically, it includes a carburetor body 100, the carburetor body 100 has a through hole 101, and also includes a frame 200 and an annular base 300 rotatably mounted on the frame 200. A group of placement seats 301 and a clamping mechanism 400 are arranged on the annular base 300 in an annular shape and equidistantly. The clamping mechanism 400 includes a pair of clamping plates 401 that are symmetrical and independently rotatably arranged on both sides of the placement seat 301, and a driving component that drives the two clamping plates 401 to perform synchronous reverse rotation. The driving component includes a connecting pipe 402 coaxially mounted in the annular base 300, and the connecting pipe 402 A group of piston cylinders 403 are fixedly connected to the side, and a piston rod 404 is arranged on the piston cylinder 403. The piston rod 404 and the opposite ends of the two clamping plates 401 are hinged by connecting pieces 405 respectively. When the piston rod 404 moves outward, it pushes the two clamping plates 401 to expand. On the contrary, when the piston rod 404 moves inward, it pushes the two clamping plates 401 to close and clamp the carburetor body 100. Among them, a hollow rotating shaft 302 is arranged on the side of the annular base 300, and the connecting pipe 402 is coaxial with the rotating shaft 302 and is located inside the rotating shaft 302. The outer end of the connecting pipe 402 extends to the outside of the rotating shaft 302 and is connected to an external pneumatic device. The rotating shaft 302 is driven by an external driving device to perform intermittent rotation.

[0040] Preferably, please refer to Figure 1 and Figure 3 In this embodiment, the placement seat 301 and the clamping mechanism 400 are respectively arranged in three positions, and the three clamping mechanisms 400 correspond to the carburetor body 100 placed on the placement seat 301 respectively and independently. The positions of the three placement seats 301 correspond to the loading station, drilling station and unloading station of the carburetor body 100 in a clockwise direction. The annular base 300 is rotatably installed on the frame 200, and a group of placement seats 301 for placing the carburetor body 100 and the carburetor body 100 are arranged on the annular base 300. The clamping mechanism 400 for fixing the carburetor body 100 allows the loading and unloading operations of the carburetor body 100 to be carried out at the loading and unloading stations during the drilling process when drilling is being performed on the carburetor body 100 located at the drilling station, so that the loading and unloading process is synchronized with the drilling process. At the same time, after drilling a hole on the carburetor body 100, it is convenient to quickly rotate the loaded carburetor body 100 to the drilling station, thereby improving the continuity of the drilling process and correspondingly improving the processing efficiency of the carburetor body 100.

[0041] For further information, please refer to Figure 1 to Figure 2 The frame 200 includes a first L-shaped support frame 201 and a second L-shaped support frame 202. The second L-shaped support frame 202 is detachably mounted on the first L-shaped support frame 201 through fasteners. The annular base 300 rotates between the first L-shaped support frame 201 and the second L-shaped support frame 202, which facilitates the disassembly and assembly process of the annular base 300 and facilitates subsequent maintenance work related to the device.

[0042] For further information, please refer to Figures 4 to 7 The middle part of the clamping plate 401 has a columnar protrusion 4011, and the annular base 300 is provided with a mounting opening 303 matched with the protrusion 4011. The protrusion 4011 is rotatably set in the mounting opening 303. The protrusion 4011 and the side walls of the mounting opening 303 are penetrated by an axial hole, and the clamping plate 401 can rotate along the axial hole. Correspondingly, in a specific implementation, the clamping plates 401 located on both sides of the placement seat 301 rotate towards each other to clamp and fix the carburetor body 100 placed on the placement seat 301. Correspondingly, the columnar protrusion 4011 cooperates with the mounting opening 303, and can also reduce the probability of the coolant sprayed on the carburetor body 100 flowing into the inside of the annular base 300 during the drilling process.

[0043] For further information, please refer to Figure 3A pair of inner support seats 304 are provided in the middle of the annular base 300, one of which is fixed in the annular base 300, and the two inner support seats 304 are detachably connected by fasteners. The middle of the two inner support seats 304 has a connecting port 305 for the connecting pipe 402 to pass through, and the opposite sides thereof are provided with an arc-shaped groove 306 for the installation of the piston cylinder 403. By providing a detachable inner support seat 304, the disassembly and assembly process of the clamping mechanism 400 is facilitated, thereby further improving the practicality of the device.

[0044] Specifically, refer to Figure 2 and Figure 4 When assembling the device, first pass the connecting tube 402 through the hollow rotating shaft 302, and the corresponding piston cylinder 403 is located in the corresponding arc-shaped groove 306, and then fix the two inner support seats 304 by fasteners such as bolts and nuts, and then install the rotating shaft 302 on one side of the annular base 300 on the first L-shaped support frame 201 through a bearing member, wherein the rotating shaft 302 passes through the first L-shaped support frame 201, and the connecting tube 402 extends out of the outer end of the rotating shaft 302, which is convenient for connecting with an external pneumatic device to drive the piston rod 404 to work, and the second L-shaped support frame 202 is installed on the first L-shaped support frame 201 by bolts and nuts. The process is simple and easy to operate. Among them, a shaft body coaxial with the rotating shaft 302 can also be set on the side of the movable inner support seat 304, and the shaft body can be solid and can be installed on the second L-shaped support frame 202 through a bearing member to improve the rotation stability of the annular base 300.

[0045] For further information, please refer to Figures 3 to 5 The connecting tube 402 has a first channel 4021 and a second channel 4022, the first channel 4021 is located inside the second channel 4022, the second channel 4022 is annular, and a pair of annular tubes 406 are also provided on the connecting tube 402, the two annular tubes 406 are respectively connected to the corresponding first channel 4021 and second channel 4022, one of the annular tubes 406 is connected to the outer end of the piston cylinder 403, and the other annular tube 406 is connected to the inner end of the piston cylinder 403, the piston block at the inner end of the piston rod 404 is located in the middle of the piston cylinder 403, and the connecting tube 402 is connected to an external pneumatic device, such as Figure 2The pneumatic connector (not numbered in the figure) shown on the far right is fixed, and the connecting pipe 402 is rotatably connected to the connecting end of the pneumatic connector and keeps a seal. The pneumatic connector is provided with two connecting pipe openings, which are respectively connected to the first channel 4021 and the second channel 4022. In specific implementation, through the synchronous cooperation of the two connecting pipe openings, one of which is in an input state and the other is in an output state, the piston block located in the piston cylinder 403 can be stably moved in the piston cylinder 403, thereby providing a stable clamping force for the carburetor body 100 located on the placement seat 301, and maintaining the stability of the carburetor body 100 during the drilling process;

[0046] For corresponding Figures 2 to 3 The frame 200 is also provided with a limiter for limiting the displacement of the piston rod 404 at the non-processing position (i.e., the loading station and the unloading station). The limiter includes a pair of limit plates 500. The two limit plates 500 are detachably mounted on the corresponding first L-shaped support frame 201 and the second L-shaped support frame 202 through fasteners. An annular slide groove 501 is provided on the limit plate 500. A fixing rod 4041 is provided at the end of the piston rod 404. The outer end of the fixing rod 4041 is slidably arranged in the annular slide groove 501. An extension groove 502 is also provided on the annular slide groove 501 at the non-processing position. Through the annular slide groove 501 and the extension groove 502, a single pneumatic device is used to drive the three movable parts. The plug cylinder 403 makes corresponding movements synchronously. Specifically, the piston rod 404 at the drilling station is limited by the radial position of the fixed rod 4041 (that is, the annular groove 501 limits the fixed rod 4041). When the pneumatic device is working, the position of the piston rod 404 at the drilling station remains stationary, while the fixed rod 4041 at the loading station and the unloading station can move in the extension groove 502, that is, the piston rods 404 at the two locations are in a movable state. Correspondingly, the clamping plates 401 at the loading station and the unloading station can make synchronous reverse rotation movements accordingly, so that the workers can remove the carburetor body 100 after the drilling process, and the carburetor body 100 to be processed can be placed at the loading station.

[0047] For further information, please refer to Figures 3 to 5The placement seat 301 is also provided with a positioning column 307, the bottom of the positioning column 307 is adapted to the through hole 101 on the carburetor body 100, the upper part of the positioning column 307 is truncated, and the annular base 300 is also elastically provided with a blanking piece for pushing the carburetor body 100 placed on the positioning column 307 to detach. Through the provided positioning column 307, it is convenient to place the carburetor body 100 in the middle position of the placement seat 301, which is beneficial for the clamping plates 401 on both sides to clamp and fix it. At the same time, the upper part of the positioning column 307 is truncated, which is convenient for taking and placing the carburetor body 100. Correspondingly, the bottom of the positioning column 307 is adapted to the through hole 101 on the carburetor body 100, that is, the diameter is consistent, and it can also provide an internal support for the carburetor body 100, which is more conducive to ensuring the stability of the carburetor body 100 during the drilling process.

[0048] For further information, please refer to Figure 6 to Figure 7 In the specific drilling process, the carburetor body 100 will drill some working holes on the side that penetrate the carburetor body 100 and the middle through hole 101. Therefore, the positioning column 307 is also provided with an avoidance hole 3071 that is compatible with the drilling path of the carburetor body 100.

[0049] For further information, please refer to Figure 3 , Figure 6 to Figure 7 The blanking piece includes a push block 600 fixedly arranged on the inner side of the annular base 300 by an elastic piece 602, a set of push rods 601 surrounding the side of the positioning column 307 are fixed on the outer end of the push block 600, and a movable hole 603 for the push rod 601 to be inserted and connected is opened on the placement seat 301. Through the set blanking piece, the carburetor body 100 at the blanking station (i.e., the station after drilling is completed) can be smoothly separated from the positioning column 307. Specifically, the piston rod 404 is driven to move outward. In the embodiment, the fixing rod 4041 moves in the extension groove 502, and the end of the piston rod 404 squeezes the push block 600, so that the push rod 601 protrudes from the movable hole 603, and the carburetor body 100 is pushed away from the positioning column 307. It should be noted that since the upper part of the positioning column 307 is frustum-shaped, that is, it is separated from the through hole 101 on the carburetor body 100, it is only necessary that the part of the push rod 601 that is movable and protrudes from the placement seat 301 is greater than or equal to the height at which the bottom of the positioning column 307 contacts the through hole 101.

[0050] For further information, please refer to Figures 2 to 3 The length of the extension groove 502 below the limit plate 500 is greater than the length of the extension groove 502 above it, and a gap is left between the top end of the piston rod 404 and the push block 600. When the fixed rod 4041 located above abuts against the inner wall of the extension groove 502 located above, the end of the piston rod 404 located below abuts against the push block 600 located below.

[0051] In the specific implementation process, when the external pneumatic device is working, the fixed rod 4041 and the piston rod 404 at the drilling station are in a static state, that is, the clamping plate 401 remains fixed to the carburetor body 100, and the carburetor body 100 is in the drilling process. The fixed rods 4041 at the loading station and the unloading station move in the extension groove 502, so that the outer ends of the clamping plates 401 at the two stations are separated from the placement seat 301. When the fixed rod 4041 at the loading station abuts against the extension groove 502, the outer ends of the corresponding piston rods 404 are in contact with or separated from the push block 600. (the push block 600 is still in a stationary state), that is, the push rod 601 is located in the movable hole 603, which is convenient for placing the carburetor body 100 at the loading station. Correspondingly, the piston rod 404 at the unloading station continues to move along the extension groove 502, that is, squeezing the push block 600, so that the carburetor body 100 at the unloading station falls under the action of gravity and the push rod 601, completing the process of automatically unloading the carburetor body 100 with a hole drilled, so that there is no need to manually remove the carburetor body 100, providing workers with more time for loading and unloading, and further improving the practicality and convenience of the device.
