Description

Technical Field

[0001] This utility model relates to the technical field of carburetor fixing fixtures, and in particular to a quick-change fixture for automatic carburetor processing. Background Technology

[0002] The carburetor is a key component in a gasoline engine used to mix air and fuel, and is commonly found in traditional gasoline engines such as chainsaws.

[0003] Because of the complex internal structure of the carburetor, it is usually machined using CNC. In order to successfully machine the carburetor, a fixture is needed to clamp and fix it.

[0004] However, due to the large number of carburetor models and their different structures, designing a matching fixture for each carburetor model would mean that when a particular carburetor model is discontinued, the matching fixture would simply be stored in the warehouse and no longer used. This would result in excessive fixture investment costs. Therefore, to reduce the material cost of fixtures and improve their compatibility, this application proposes a quick-change fixture for automatic carburetor machining. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick-change fixture for automatic carburetor processing that can be used to fix different models of carburetors, thereby improving the compatibility of fixture components and reducing fixture costs.

Detailed Implementation

[0031] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0032] like Figure 1 and Figure 2 As shown, an automatic carburetor processing quick-change fixture 10 includes a base 100 and a clamping assembly 200. The clamping assembly 200 includes a material carrier block 210, a pusher drive 220, a pusher block 230, a pressure drive 240, and a pressure member 250. The material carrier block 210 is detachably mounted on the base 100 and is used to support the carburetor. The pusher drive 220 is mounted on the base 100, and the pusher block 230 passes through the material carrier block 210. The pusher block 230 and the pusher drive 220 are connected. The output shaft of 0 is connected, and the pusher drive 220 is used to drive the pusher block 230 to extend from the top surface of the load block 210 to push the carburetor away from the load block 210. The pressing drive 240 is set on the base 100. One end of the pressing member 250 is connected to the pressing drive 240, and the other end of the pressing member 250 extends to the top of the load block 210. The pressing drive 240 is used to drive the pressing member 250 close to the load block 210 so that the pressing member 250 and the load block 210 together clamp the carburetor.

[0033] It should be noted that the carrier block 210 is used to support and fix the carburetor. For different carburetor models, only the carrier block 210 needs to be replaced. Specifically, the carrier block 210 is mounted on the base 100 with screws. The pusher block 230 passes vertically through the carrier block 210. The pusher drive 220 is mounted on the base 100, and the output shaft of the pusher drive 220 is connected to the pusher block 230. Thus, the pusher drive 220 drives the pusher block 230 to move up and down relative to the carrier block 210. When the pusher block 230 rises, it can push the carburetor away from the carrier block 210. Furthermore, the pressure drive 240 is mounted adjacent to the load block 210 on the base 100, and the pressure member 250 is mounted on the output shaft of the pressure drive 240. The pressure drive 240 drives the pressure member 250 to move up and down, thereby enabling the pressure member 250 to press the carburetor onto the load block 210 or release the carburetor. In one embodiment, both the push drive 220 and the pressure drive 240 are cylinders. Thus, by mounting the load block 210 onto the base 100 with screws, different load blocks 210 can be installed and fixed according to different carburetors, making the remaining components reusable. Only the load block 210 needs to be replaced, which improves the reusability of components other than the load block 210, thereby reducing the overall cost of the fixture.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, there are two of each of the following components: a material carrier 210, a pusher drive 220, a pusher block 230, and a pressing component 250. The two material carriers 210 are detachably disposed on both sides of the pressing drive 240. The two pusher blocks 230 are respectively inserted through the two material carriers 210 and are respectively connected to the output shafts of the two pusher drives 220. One end of each of the two pressing components 250 is connected to the output shaft of the pressing drive 240, and the other end of each pressing component 250 extends above the two material carriers 210. The pressing drive 240 is used to simultaneously drive the two pressing components 250 to move closer to or further away from the two material carriers 210.

[0035] It should be noted that, in order to improve the efficiency of the automatic carburetor processing quick-change fixture 10, two of each are provided: the loading block 210, the pushing drive component 220, the pushing block 230, and the pressing component 250. This allows the pressing drive component 240 to simultaneously drive both pressing components 250 to descend, thereby clamping two carburetors at the same time. Thus, compared to existing fixtures that can only fix a single carburetor, the automatic carburetor processing quick-change fixture 10 of this application has two fixed stations, and therefore can fix two carburetors at a time.

[0036] like Figure 1As shown, in one embodiment, two spaced-apart support block groups are provided on the base 100, and the material pressing drive 240 is located between the two support block groups. The support block group includes two support blocks 110, and the two support blocks 110 jointly support the two ends of a material block 210.

[0037] It should be noted that the two support blocks 110 form a group to jointly support the material block 210. In one embodiment, the support block 110 and the base 100 are integrally formed to ensure sufficient structural strength between the support block 110 and the base 100.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, a positioning cone block 261 is provided on the support block 110, and a positioning cone sleeve 262 is provided on the material block 210. The positioning cone block 261 and the positioning cone sleeve 262 are appropriately matched.

[0039] It should be noted that the above structure is designed to enable the material carrier block 210 to be quickly and accurately positioned with the support block 110. Specifically, the outer wall of the positioning cone block 261 has an inverted conical outer wall, and the inner wall of the positioning cone sleeve 262 has an inverted conical inner wall, so that the positioning cone block 261 and the positioning cone sleeve 262 can be quickly and accurately fitted together. In one embodiment, a positioning cone block 261 is installed on each of the two support blocks 110 used to support the same material carrier block 210, and a positioning cone sleeve 262 is installed on each end of the bottom side surface of the material carrier block 210. In this way, the two positioning cone blocks 261 are fitted with the two positioning cone sleeves 262 respectively. When it is necessary to replace the material carrier block 210, the material carrier block 210 can be quickly and accurately positioned on the support block 110 through the fitted structure of the positioning cone block 261 and the positioning cone sleeve 262. Finally, after passing the screw through the material carrier block 210, the positioning cone sleeve 262, and the positioning cone block 261, it is directly screwed onto the support block 110, so that the material carrier block 210 can be fixedly installed on the support block 110.

[0040] like Figure 5 As shown, in one embodiment, a first air passage 111 is provided in the support block 110, and a second air passage 211 is provided in the material block 210. One end of the second air passage 211 is connected to the first air passage 111, and the other end of the second air passage 211 extends to the top surface of the material block 210.

[0041] It should be noted that the above structure is designed to ensure that the carburetor is reliably clamped and fixed to the carrier block 210 by the pressure member 250. Specifically, an air inlet is installed on the end of the first air passage 111 away from the second air passage 211, and the air inlet is connected to an external air source with a pressure sensor through a pipe. When the carburetor is reliably clamped and fixed to the carrier block 210 by the pressure member 250, the carburetor blocks the opening at the top surface of the second air passage 211 on the carrier block 210. Conversely, when the carburetor is not reliably clamped, there is a gap between the carburetor and the carrier block 210. Therefore, the air pressure sensor can be used to detect whether the carburetor is reliably clamped and fixed. In addition, it should be noted that when the carrier block 210 is replaced, the second air passage 211 can be quickly connected to the first air passage 111.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, two fixed feed columns 270 are detachably provided on the feed block 210, and the two fixed feed columns 270 are used to pass through the carburetor.

[0043] It should be noted that the feed post 270 is fixed to the feed block 210 by screws, so that the two feed posts 270 pass through the carburetor for fixation. In this way, when different feed blocks 210 are replaced, the feed posts 270 can be installed on different feed blocks 210 for reuse.

[0044] like Figure 1 and Figure 6 As shown, in one embodiment, the pressing component 250 includes a pressing block 251, a connecting block 252, a buffer block 253, a guide rod 254, and a spring 255. The guide rod 254 is vertically disposed on the base 100 or the pressing drive component 240, and the guide rod 254 passes through the buffer block 253. The spring 255 is sleeved on the guide rod 254, and both ends of the spring 255 abut against the buffer block 253 and the guide rod 254, respectively. The spring 255 is used to push the buffer block 253, which has a tendency to slide downward in the vertical direction. Both ends of the connecting block 252 are rotatably connected to the middle part of the pressing block 251 and the buffer block 253, respectively. One end of the pressing block 251 is rotatably connected to the output shaft of the pressing drive component 240, and the other end of the pressing block 251 extends above the loading block 210.

[0045] It should be noted that the guide rod 254 can be fixedly mounted on the base 100 or on the pressure drive component 240. Specifically, the pressure drive component 240 is fixedly mounted on the base 100 with screws. For example, if the pressure drive component 240 is a cylinder, the guide rod 254 can be fixedly mounted on the cylinder body using a plate. The guide rod 254 is arranged vertically. The guide rod 254 passes through the buffer block 253, allowing the buffer block 253 to move up and down along the axial direction of the guide rod 254. A spring 255 is sleeved on the guide rod 254, and the spring 255 abuts against both the buffer block 253 and the guide rod 254. The spring 255 pushes the buffer block 253, causing the buffer block 253 to tend to move downwards vertically. Furthermore, the adapter block 252 is rotatably connected to the middle positions of the buffer block 253 and the pressure block 251 via pins. Furthermore, one end of the pressure block 251 is rotatably connected to the output shaft of the pressure drive 240 via a pin, while the other end of the pressure block 251 extends above the load block 210. Thus, when the pressure drive 240 pushes one end of the pressure block 251 upwards, the middle of the pressure block 251 is connected by the adapter block 252, forming a lever. Therefore, the end of the pressure block 251 located on the load block 210 descends to press the carburetor firmly against the load block 210. When the pressure block 251 abuts against the carburetor, as the pressure drive 240 continues to push the pressure block 251, the adapter block 252 pulls the buffer block 253 upwards along the guide rod 254, compressing the spring 255. Finally, under the elastic pressure of the spring 255, the pressure block 251 reliably presses and fixes the carburetor onto the load block 210.

[0046] like Figure 1 As shown, in one embodiment, two guide rods 254 and two springs 255 are provided. The two guide rods 254 are both inserted through the buffer block 253, and the two springs 255 are respectively sleeved inside the two guide rods 254. In this way, it is ensured that the buffer block 253 can stably move up and down in the vertical direction.

[0047] like Figure 6 As shown, in one embodiment, the pressure block 251 has two pressure arms 2511 at one end near the material block 210, and the two pressure arms 2511 are used to jointly press the carburetor. In this way, the carburetor is reliably pressed and fixed on the material block 210 by the two pressure arms 2511 together.

[0048] like Figure 6 As shown, in one embodiment, a pressure pad 256 is provided on the side of the pressure arm 2511 near the material block 210.

[0049] It should be noted that the pressure block 251 is made of metal. To prevent the pressure block 251 from directly contacting the carburetor and scratching it, a pressure pad 256 is installed on the bottom side of the pressure arm 2511. In one embodiment, the pressure pad 256 is made of soft rubber.

[0050] like Figure 6 As shown, in one embodiment, the pressure arm 2511 has an arc groove 2511a, and the pressure pad 256 has a cylinder 2561, which is adapted to be rotatably disposed in the arc groove 2511a.

[0051] It should be noted that a clearance groove is provided in the middle of the cylinder 2561. The cylinder 2561 is inserted laterally into the arc groove 2511a. Then, a screw is inserted from the top of the pressure arm 2511, with the end of the screw located in the clearance groove. In this way, the pressure pad 256 can rotate within the arc groove 2511a but cannot slide out of it. This allows the pressure pad 256 to reliably press against the carburetor.

[0052] like Figure 7 As shown, in one embodiment, the pusher block 230 has a clearance hole 231 on one side near the pusher drive member 220. The output shaft of the pusher drive member 220 is provided with a height-adjustable clamping bolt 221. The inner diameter of the clearance hole 231 is larger than the outer diameter of the clamping bolt 221. The pusher block 230 is provided with two clamping screws in the horizontal direction. The clamping screws pass through the clearance hole 231 to clamp the clamping bolt 221.

[0053] It should be noted that when different material carrier blocks 210 are replaced, the pusher block 230 needs to be re-inserted onto the material carrier block 210 to adapt it. In order to avoid the problem of squeezing between the pusher block 230 and the material carrier block 210, that is, to ensure that the pusher block 230 can smoothly slide up and down relative to the material carrier block 210, the pusher block 230 is set to be a structure that is loose relative to the output shaft of the pusher drive 220 and the material carrier block 210. Therefore, a structure is set to use a material clamping screw to clamp the material clamping bolt 221, so that the pusher drive 220 can drive the pusher block 230 to move up and down relative to the material carrier block 210 through the material clamping bolt 221.

[0054] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
