This tool design aims to improve the processing quality and production efficiency of the scroll disk. It is an indispensable key component in the manufacturing of precision equipment such as scroll compressors.

During the spiral processing process, the tool is embedded in the material to be processed during the output and rotation process, and after embedding the material to be processed, the material is wrapped by a sealing sheet, an upper wrapping frame and a lower wrapping frame to wrap and prevent the splashing of debris. While collecting the debris, external gas is extracted from the air duct position. The gas can drive the debris to pass through the first filter and be uniformly stored in the storage barrel. The debris collected in the storage barrel can be uniformly processed and discharged. The problems raised in the above-mentioned background technology are solved.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a vortex equidistant tool processing tool, comprising a transmission mechanism, a tool is arranged at the lower end of the transmission mechanism, a base is arranged at the lower end of the tool, a lower wrapping frame is arranged around the outside of the base, an upper wrapping frame is arranged at the upper end of the outside of the lower wrapping frame, a sealing plate is arranged between the tool and the transmission mechanism, the middle position inside the sealing plate will be rotatably connected to the external connection position of the tool, and a first filter is arranged around the lower end of the base and the lower end of the lower wrapping frame.

[0007] Preferably, an air duct is sealed on one side of the outer side of the upper wrapping frame, and one end of the air duct is connected to a fan.

[0008] Preferably, a storage bucket is welded to the lower end of the lower wrapping frame, a second filter is provided on one side of the outer wall of the storage bucket, and the exterior of the second filter is an integral structure with the storage bucket.

[0009] Preferably, a filling plug is provided at the lower end of the storage bucket, and the upper end of the outside of the filling plug is connected to the lower end slot inside the storage bucket, and the four corners of the filling plug are fixedly connected to the lower end of the storage bucket by bolts.

[0010] Preferably, limiting frames are provided on both sides of the outside of the upper wrapping frame, and a threaded rod is longitudinally provided inside one of the limiting frames, and the outside of the threaded rod passes through one side of the outside of the upper wrapping frame and cooperates with the threaded position of the passing position, and the other side of the upper wrapping frame is embedded in the inside of another limiting frame and is slidably connected to the inside of the limiting frame.

[0011] Preferably, an adapting groove is provided inside the upper wrapping frame toward the lower wrapping frame, and the adapting groove is connected to the card slot of the lower wrapping frame.

[0012] Preferably, a clamping mechanism is provided on the inner wall of the lower wrapping frame toward the base.

[0013] Preferably, four clamping mechanisms are arranged around.

[0014] The vortex equidistant tool processing tool and method include the following steps:

[0015] Step 1: Place the material to be cut on the upper end of the base, and then clamp it with the clamping mechanism and fix it inside the lower wrapping frame;

[0016] Step 2: The tool is driven and pushed by the transmission mechanism to contact and embed the second processing point of the material to be cut, and the tool is driven and moved so that the tool moves from the second processing point to the first processing point;

[0017] Step 3: The transmission mechanism drives the tool so that the tool performs spiral cutting from the first processing point to the third processing point;

[0018] Step 4: The transmission mechanism drives the tool so that the tool rotates and cuts from the third processing point to the fifth processing point;

[0019] Step 5: The transmission mechanism drives the tool so that the tool rotates and cuts from the fifth processing point to the fourth processing point;

[0020] Step 6: The transmission mechanism drives the tool so that the tool finally rotates and cuts from the fourth processing point position to the second processing point position, thereby completing the cutting of the scroll disk inside the air-conditioning scroll compressor.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention sequentially arranges lower wrapping frames longitudinally outside the cutting position at the upper end of the clamping mechanism. When the tool performs spiral cutting, the upper end of the lower wrapping frame will be driven by the threaded rod to make the upper wrapping frame move longitudinally downward to further wrap the base position. Finally, when the tool contacts the material to be processed, the sealing sheet will fit on the upper end of the upper wrapping frame. The sealing sheet is larger than the groove exposed at the upper end of the upper wrapping frame. Through the wrapping of the sealing sheet, the transmission mechanism can be adapted to drive the tool and adjust the position of the tool, so that the sealing sheet can continuously wrap the upper end of the upper wrapping frame, so that the debris splashed by the tool cutting can be continuously wrapped and collected by the sealing sheet, the upper wrapping frame and the lower wrapping frame.

[0023] 2. The present invention has a fan connected to one side of the outer portion of the upper wrapping frame. The fan extracts external gas, so that when the sealing sheet, the upper wrapping frame and the lower wrapping frame wrap the processing position, the external gas can be transported to the wrapping position through the air duct. A first filter is provided between the base and the storage barrel at the lower end. The weight of the debris and the driving force generated by the air flow will push the debris to pass through the first filter and be uniformly stored inside the storage barrel, while the gas will pass through the second filter and be discharged. The debris can be uniformly collected, and the debris is prevented from being retained around the base after being wrapped and affecting the material on the upper end of the base to be processed by the tool.

[0024] 3. In the cutting process of the present invention, the inner line is cut first, and the second processing point is embedded in the material to be processed. The tool moves through the first processing point, the third processing point, the fifth processing point and the fourth processing point in sequence. After cutting to the fourth processing point, the fourth processing point moves along the previous cutting path after the first processing point, cuts the outer line, and cuts from the first processing point counterclockwise to the second processing point to complete the spiral processing, thereby reducing the overall length of the spiral cutting and reducing the damage to the tool during a single spiral cutting process. When the fourth processing point moves to the first processing point, the tool will not contact the material to be processed. The temperature of the tool can be reduced during the movement to avoid continuous contact between the tool and the high temperature at the cutting position, thereby providing the tool with an area for cooling down and improving the tool life.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with specific embodiments.

[0035] Example 1

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, a vortex equidistant tool processing tool of the present embodiment includes a transmission mechanism 1, and a tool 3 is arranged at the lower end of the transmission mechanism 1. The tool 3 can be driven to adjust its position by the push of the internal telescopic structure of the transmission mechanism 1 to achieve vortex cutting and processing, and the motor built into the transmission mechanism 1 can drive the tool 3 to rotate when it is started. The rotation of the tool 3 and the internal telescopic structure of the transmission mechanism 1 can achieve spiral cutting processing;

[0037] The lower end of the cutter 3 is provided with a base 9, and the material to be cut and processed needs to be placed on the upper end of the base 9 before processing, and the material is supported by the base 9. Figure 2 and Figure 3 As shown, a lower wrapping frame 5 is disposed around the outside of the base 9, and a clamping mechanism 7 is disposed on the inner wall of the lower wrapping frame 5 toward the base 9, and four clamping mechanisms 7 are disposed around the base 9. After the material to be cut and processed is placed on the upper end of the base 9, the clamping mechanisms 7 clamp and fix the four corners of the material to be cut and processed;

[0038] In addition, an upper wrapping frame 4 is provided at the upper end of the outer portion of the lower wrapping frame 5, and limiting frames 13 are provided on both sides of the outer portion of the upper wrapping frame 4, wherein a threaded rod 14 is longitudinally provided inside one of the limiting frames 13, and the outer portion of the threaded rod 14 passes through one side of the outer portion of the upper wrapping frame 4 and cooperates with the threaded portion of the passing position, and the other side of the upper wrapping frame 4 is embedded in another limiting frame 13 and is slidably connected to the inner portion of the limiting frame 13, and after the threaded rod 14 is output by the motor, the limiting frames 13 on both sides limit the two sides of the upper wrapping frame 4, so that the upper wrapping frame 4 can be converted from a rotational motion into a longitudinal linear motion, and the longitudinal linear motion of the upper wrapping frame 4 can move toward the upper end of the lower wrapping frame 5;

[0039] In order to improve the fit between the upper wrapping frame 4 and the lower wrapping frame 5, it is convenient to collect the cutting fragments later. Figure 3 As shown, an adapting groove 15 is provided inside the upper wrapping frame 4 facing the lower wrapping frame 5, and the adapting groove 15 is connected with the card slot of the lower wrapping frame 5. As the threaded rod 14 rotates, the upper wrapping frame 4 is pushed, and the upper wrapping frame 4 is pushed so that the lower wrapping frame 5 is embedded in the adapting groove 15. The depth of the lower wrapping frame 5 embedded in the adapting groove 15 can adapt to the cutting depth of the tool 3.

[0040] In order to prevent the debris wrapped in the upper wrapping frame 4 and the lower wrapping frame 5 from splashing when the cutter 3 rotates and cuts, Figure 1 and Figure 2As shown, a sealing sheet 2 is provided between the cutter 3 and the transmission mechanism 1. The sealing sheet 2 will move longitudinally downward together with the cutter 3, and the middle position inside the sealing sheet 2 will be rotatably connected with the external connection position of the cutter 3. When the cutter 3 moves longitudinally downward, the sealing sheet 2 will be precisely fitted with the upper wrapping frame 4, and the sealing sheet 2 can be prevented from rotating by fitting, and the sealing sheet 2 can wrap the upper end of the upper wrapping frame 4 to prevent the fragments from splashing;

[0041] Among them, a first filter screen 10 is arranged around the lower end of the base 9 and the lower end of the lower wrapping frame 5, and the two ends of the first filter screen 10 are respectively integrated with the outside of the base 9 and the inside of the lower wrapping frame 5. After the crushed powder is wrapped by the sealing sheet 2, the upper wrapping frame 4 and the lower wrapping frame 5, the crushed powder will pass through the first filter screen 10 and be discharged. Figure 2 and Figure 6 As shown, a storage bucket 6 is provided at the lower end of the lower wrapping frame 5, and the upper end of the storage bucket 6 is welded and fixed to the lower end of the lower wrapping frame 5, and the debris passing through the first filter 10 will be uniformly collected inside the storage bucket 6;

[0042] In order to prevent some debris from being unable to pass through the first filter screen 10 and enter the storage barrel 6 by its own weight, and to prevent the debris trapped around the lower wrapping frame 5 from affecting the cutting of the material, as shown in FIG. Figure 2 , Figure 4 and Figure 6 As shown, an air duct 8 is sealed on one side of the outer side of the upper wrapping frame 4, and one end of the air duct 8 is sealed and connected to the outer wall of the upper wrapping frame 4, and one end of the air duct 8 is connected to a fan, and the fan corresponding to the air duct 8 can blow gas toward the sealing sheet 2, the upper wrapping frame 4 and the lower wrapping frame 5 through the air duct 8, and the gas can actively drive the crushed powder to pass through the first filter screen 10, and a second filter screen 11 is provided on one side of the outer wall of the storage barrel 6, and the outer side of the second filter screen 11 is an integrated structure with the storage barrel 6. After the gas drives the crushed powder into the storage barrel 6, the gas will directly pass through the second filter screen 11 and be discharged, and the mesh number of the second filter screen 11 is much smaller than the size of the crushed powder;

[0043] Among them, a filling plug 12 is provided at the lower end of the storage bucket 6, and the upper end of the outer portion of the filling plug 12 is connected to the lower end slot of the storage bucket 6, such as Figure 4 and Figure 6 As shown, the four corners of the filling plug 12 are fixedly connected to the lower end of the storage barrel 6 by bolts. After the debris enters the storage barrel 6, it will continue to stay at the upper end of the outside of the filling plug 12. After the filling plug 12 is removed, the collected debris can be fully discharged.

[0044] The vortex equidistant tool processing tool and method include the following steps:

[0045] Step 1: Place the material to be cut on the upper end of the base 9, and then clamp it with the clamping mechanism 7 and fix it inside the lower wrapping frame 5;

[0046] Step 2: The tool 3 is driven and pushed by the transmission mechanism 1 to make it contact and embed into the second processing point 17 of the material to be cut, and the tool 3 is driven and moved so that the tool 3 moves from the second processing point 17 to the first processing point 16;

[0047] Step 3: The transmission mechanism 1 drives the tool 3 so that the tool 3 performs spiral cutting from the first processing point 16 to the third processing point 18;

[0048] Step 4: The transmission mechanism 1 drives the tool 3 so that the tool 3 rotates and cuts from the third processing point 18 to the fifth processing point 20;

[0049] Step 5: The transmission mechanism 1 drives the tool 3 so that the tool 3 rotates and cuts from the fifth processing point 20 to the fourth processing point 19;

[0050] Step 6: The transmission mechanism 1 drives the tool 3, so that the tool 3 finally rotates and cuts from the fourth processing point 19 to the second processing point 17, thereby completing the cutting of the scroll disk inside the air-conditioning scroll compressor.

[0051] Working principle: the material to be cut is placed on the upper end of the base 9, and the material to be cut is clamped by the four surrounding clamping mechanisms 7. After clamping and fixing, the threaded rod 14 is restricted by the limiting frame 13 after passing through the output of the motor, so that the limiting frame 13 is converted from rotational motion to longitudinal linear motion. The longitudinal linear motion of the limiting frame 13 can drive the upper wrapping frame 4 to move downward longitudinally, and the lower wrapping frame 5 will be embedded in the adapter groove 15 position inside the upper wrapping frame 4. The transmission of the internal transmission structure of the transmission mechanism 1 can push the tool 3 to pass through the upper wrapping frame 4 and approach the material to be cut clamped by the clamping mechanism 7. With the push and drive of the transmission mechanism 1, the rotating tool 3 can be driven to embed into the second processing point 17 position of the material to be cut. After embedding into the second processing point 17 position, with the transmission of the transmission mechanism 1, the second processing point 17 is sequentially moved along the pre-designed trajectory. After cutting toward the first processing point 16, the third processing point 18, the fifth processing point 20 and the fourth processing point 19, it finally returns to the second processing point 17 position, and vortex cutting is realized after the cycle is completed. The debris generated in the cutting process will first be blocked by the sealing sheet 2 at the upper end of the outer side of the tool 3 and then attached to the upper end of the upper wrapping frame 4. The fan will transmit gas to the upper wrapping frame 4 through the air duct 8. The gas will drive the internal splashing debris to flow toward the first filter 10. After passing through the first filter 10, the debris and gas will enter the storage barrel 6. After entering the storage barrel 6, the debris will accumulate at the upper end of the filling plug 12, and the gas will directly pass through the second filter 11 and be discharged. When cleaning the debris uniformly later, after rotating and removing the bolts that penetrate the filling plug 12 and are embedded in the storage barrel 6, remove the filling plug 12, and the debris can be taken out from the filling position of the filling plug 12.
