Description

Technical Field

[0001] The invention relates to the field of automatic tapping equipment, and in particular to a device and method for tapping a tapered workpiece. Background Art

[0002] Automatic tapping machines are used for tapping, threading, and other processing machinery for hardware parts such as nuts and other parts, to achieve automation, reduce labor and save costs. In the existing automatic tapping machines, during the tapping process, the processed parts are mixed with waste materials, which need to be separated by division of labor, increasing the workload. At the same time, the traditional tapping method is realized by clamping, with a cylinder in the middle as the tapping workpiece. The center positioning accuracy of the product mainly depends on the accuracy of the cylindrical workpiece being processed, which is relatively simple and easy to control. If the tapered workpiece is still implemented in the old-fashioned clamping method, it may cause center positioning deviation, because the deviation of the tapered workpiece may occur on the taper or in the parallel direction of the taper, which ultimately leads to inaccurate positioning of the clamping method and causes problems with product quality. Therefore, a device and method for tapping a tapered workpiece are proposed. Summary of the invention

[0014] A method for machining a tapered workpiece comprises the following steps:

[0015] Step 1: Place the original conical workpiece to be processed on the feed rack, and the feed rack transports the raw material to be processed to the feeding mechanism through the continuous vibration of the vibration motor;

[0016] Step 2: When the raw material to be processed is transported to the feeding mechanism, the raw material to be processed is pushed under the raw material clamping plate, and then the propulsion cylinder on the mounting table operates to push the feeding structure into the processing mechanism through the pushing column for processing;

[0017] Step 3: After the raw materials to be processed are pushed into the processing mechanism, the first hydraulic box and the second hydraulic box operate to lift the first hydraulic column and the second hydraulic column. The first hydraulic column and the second hydraulic column are lifted upward, thereby driving the lifting frame to rise from the inside of the first processing frame and the second processing frame. When the lifting frame is lifted, the raw materials to be processed pushed into the lifting frame will be lifted.

[0018] Step 4: When the lifting rack lifts the raw material to be processed, the propulsion cylinder operates to retract the push column, thereby driving the feeding mechanism to retract from the processing mechanism. During the retraction of the feeding mechanism, the lifting cylinder arranged in the clamping plate fixing frame operates to lift the raw material clamping plate through the push column, so that the raw material to be processed falls into the lifting rack. After the raw material to be processed falls into the lifting rack, it can be lifted by the lifting rack;

[0019] Step 5: The lifting frame is raised to lift the raw material to be processed and inserted into the processing hole inside the processing mold on the processing block. Then the tapping drill bit is inserted into the processing hole to perform tapping operation on the raw material to be processed. During the tapping operation, the tapping drill bit needs to be sprayed with water to cool it down.

[0020] Step 6: After the tapping is completed, the third hydraulic box in the material-returning mechanism operates, and the third hydraulic box operates to push the linkage rod, and the linkage rod then drives the material-returning block to press down through the transmission shaft, and presses the processed raw material embedded in the processing hole back to the lifting rack;

[0021] Step 7: After the processed raw materials are pressed back onto the lifting rack, the feeding mechanism operates again to drag the next raw material to be processed into the processing mechanism. The raw materials to be processed pushed into the processing mechanism again will push the processed raw materials out of the lifting rack and fall into the receiving box;

[0022] Step 8: The waste generated when tapping the raw material to be processed will fall into the waste hole on the waste discharge mechanism, and the waste will be discharged from the waste pipe through the waste hole.

[0023] Compared with the prior art, the present invention has the following advantages: the conical workpiece tapping device and method can transport the raw material to be processed from below to the processing hole pushed into the processing mold from below for tapping, which also avoids the occurrence of the situation that the center of circle positioning of the product is offset, thereby improving the quality of the product processed by the device, and the waste generated during the processing will fall from the waste hole into the waste pipe for discharge, and the iron chips are separated from the product through the waste pipe and the waste hopper, reducing the situation that the product and the iron chips are mixed together, which increases the labor cost of later separation and improves production efficiency.

DETAILED DESCRIPTION

[0029] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0030] like Figures 1 to 4As shown, this embodiment provides a technical solution: a taper workpiece tapping device, comprising a base plate 1, a feeding mechanism, a feeding mechanism, a processing mechanism, a material withdrawal mechanism and a waste material discharge mechanism, wherein the feeding mechanism is used to transport the raw material to be processed, the feeding structure is used to escort the raw material to be processed transported by the feeding structure into the device, the processing mechanism is used to process the raw material to be processed input into the device, the material withdrawal mechanism is used to withdraw the processed raw material, and the waste material discharge mechanism is used to discharge the waste generated during the processing;

[0031] The feeding mechanism is arranged above the bottom plate 1 near one side, the feeding mechanism is arranged above the bottom plate 1, the processing mechanism is arranged on the upper outer surface of the bottom plate 1, the material return mechanism is arranged above the processing mechanism, and the waste discharge mechanism is arranged inside the processing mechanism.

[0032] The feeding mechanism includes a feeding rack 9 and a supporting rack. The feeding rack 9 is fixed on the base plate 1 by the supporting rack. A feeding chute is provided on the outer surface of the upper end of the feeding rack 9. The feeding mechanism is arranged on one side of the feeding mechanism. The raw materials to be processed are placed in the feeding chute on the feeding rack 9. The feeding rack 9 continuously vibrates to transport the raw materials to be processed to the feeding mechanism. The arrangement of this mechanism facilitates feeding.

[0033] The feeding mechanism includes a processing table 18, a mounting table 19, a propulsion cylinder 20 and a clamping mechanism. The processing table 18 is fixedly installed at the middle position of the upper outer surface of the base plate 1. The processing table 18 is used to receive and process the raw materials. The mounting table 19 is fixedly installed at the front end of the processing table 18. The propulsion cylinder 20 is arranged at the front end of the mounting table 19. The mounting table 19 is used to fix the propulsion cylinder and provide space for the movement of the clamping mechanism. A pushing column is arranged inside the propulsion cylinder 20, and one end of the pushing column is in contact with the clamping mechanism. When the propulsion cylinder 20 is running, the pushing column will be pushed out, which will drive the clamping mechanism to slide into the inside of the device. When the propulsion cylinder 20 is running, the pushing column will be retracted, which will drive the clamping mechanism to retract from the inside of the device. The arrangement of this structure can better and more conveniently input the raw materials to be processed into the device for processing.

[0034] The clamping mechanism includes a base 21, a clamping plate fixing frame 22, a lifting cylinder 23 and a raw material clamping plate 24. The base 21 is slidably installed on the upper outer surface of the processing table 18 near the front end, the clamping plate fixing frame 22 is fixedly installed on the upper outer surface of the base 21, and the clamping plate fixing frame 22 is used to install the raw material clamping plate 24. The lifting cylinder 23 is arranged in two groups of clamping plate fixing frames 22. A raw material clamping plate 24 is arranged between the two groups of clamping plate fixing frames 22 near the top. The raw material clamping plate 24 is used to clamp and fix the parts to be processed. A clamping block is welded on one end of the raw material clamping plate 24 away from the clamping plate fixing frame 22. The setting of the clamping mechanism effectively avoids the situation that the raw material to be processed falls when it is transported to the device for processing. The setting of the clamping block can more effectively reduce the situation that the raw material falls when the raw material to be processed is transported.

[0035] A push column is arranged inside the lifting cylinder 23, and the top end of the push column contacts the raw material clamping plate 24. The lifting cylinder 23 drives the raw material clamping plate 24 to move up and down through the push column.

[0036] The processing mechanism includes a first processing frame 2, a second processing frame 3, a first hydraulic box 4, a second hydraulic box 5, a lifting frame 8, a positioning column 28 and a processing block 10. The first processing frame 2 and the second processing frame 3 are symmetrically arranged at the middle position of the upper outer surface of the bottom plate 1. The first hydraulic box 4 is arranged on one side of the first processing frame 2, and the second hydraulic box 5 is arranged on one side of the second processing frame 3. The lifting frame 8 is arranged inside the first processing frame 2 and the second processing frame 3. The first hydraulic box 4 is provided with a first hydraulic column 6 inside, and the second hydraulic box 5 is provided with a second hydraulic column 7 inside. The first hydraulic column 6 and the second hydraulic column 7 are connected to each other. The top of the column 7 is fixedly connected to the lifting frame 8, and a processing mold 11 is embedded in the middle position of the inner part of the processing block 10. A processing hole 12 is opened in the middle position of the inner part of the processing mold 11. The drill bit used for tapping the processing hole 12 passes through the processing hole 12 to tap the original workpiece to be processed. A material trough 25 is opened on the outer surface of the upper end of the lifting frame 8. The raw material to be processed moves in the material trough 25. The method of pushing the raw material to be processed from the bottom into the processing hole 12 on the processing mold 11 through the lifting frame 8 for processing also avoids the occurrence of the center positioning deviation of the product, thereby improving the quality of the product processed by the device.

[0037] There are two groups of positioning columns 28 . The positioning columns 28 are arranged between the first processing frame 2 and the second processing frame 3 . The positioning columns 28 penetrate the lifting frame 8 . The arrangement of the positioning columns 28 can prevent deviation in tapping caused by displacement of the lifting frame 8 .

[0038] The material-returning mechanism comprises a third hydraulic box 13, a third hydraulic column 14, a linkage rod 15, a transmission shaft 16 and a fixed seat 17. The fixed seat 17 is fixedly mounted on the upper outer surface of the processing block 10. The third hydraulic box 13 is arranged on the upper outer surface of the bottom plate 1 near the rear end. The third hydraulic column 14 is arranged inside the third hydraulic box 13. The top end of the third hydraulic column 14 is connected to the linkage rod 15. One end of the linkage rod 15 is fixedly connected to the transmission shaft 16. The transmission shaft 16 passes through the fixed seat 17. A lower portion is arranged between the two sets of fixed seats 17. The material block 29 and the lower material block 29 are fixedly connected to the transmission shaft 16, a first connecting rod is arranged at the upper end of the third hydraulic column 14, a second connecting rod is arranged on the outer surface of the lower end of the linkage rod 15, pin holes are provided inside the first connecting rod and the second connecting rod, a connecting pin passes through the inside of the pin hole, the third hydraulic column 14 and the linkage rod 15 are movably connected through the connecting pin, when the tapping is completed, the processed raw material will be stuck in the processing hole 12 on the processing mold 11, and the setting of the material return mechanism can remove the raw material stuck in the processing hole 12 on the processing mold 11.

[0039] The waste discharge mechanism includes a waste pipe 27 and a waste hole 26. The waste hole 26 is opened inside the base plate 1, and the waste pipe 27 is arranged inside the waste hole 26. The waste generated during the processing will first fall into the through hole on the lifting frame 8, and then fall from the through hole into the waste pipe 27 in the waste hole 26 to be discharged. The iron filings are discharged through the waste pipe 27, thereby achieving complete separation of the waste filings from the product, and will not cause the product and the iron filings to be mixed together, thereby increasing the labor cost of later separation and improving production efficiency.

[0040] A method for machining a tapered workpiece comprises the following steps:

[0041] Step 1: Place the original conical workpiece to be processed on the feed rack 9, and the feed rack 9 transports the raw material to be processed to the feeding mechanism through the continuous vibration of the vibration motor;

[0042] Step 2: When the raw material to be processed is transported to the feeding mechanism, the raw material to be processed is pushed under the raw material clamping plate 24, and then the propulsion cylinder 20 on the mounting table 19 operates to push the feeding structure into the processing mechanism through the pushing column for processing;

[0043] Step 3: After the raw materials to be processed are pushed into the processing mechanism, the first hydraulic box 4 and the second hydraulic box 5 operate to lift the first hydraulic column 6 and the second hydraulic column 7. The first hydraulic column 6 and the second hydraulic column 7 are lifted upward, thereby driving the lifting frame 8 to rise from the inside of the first processing frame 2 and the second processing frame 3. When the lifting frame 8 is lifted, it will drive the raw materials to be processed pushed into the lifting frame 8 to rise.

[0044] Step 4: When the lifting rack 8 lifts the raw material to be processed, the propulsion cylinder 20 operates to retract the push column, thereby driving the feeding mechanism to retract from the processing mechanism. During the retraction of the feeding mechanism, the lifting cylinder 23 arranged in the clamping plate fixing frame 22 operates to lift the raw material clamping plate 24 through the push column, so that the raw material to be processed falls into the lifting rack 8. After the raw material to be processed falls into the lifting rack 8, it can be lifted by the lifting rack 8;

[0045] Step 5: The lifting frame 8 is raised to lift the raw material to be processed and inserted into the processing hole 12 inside the processing mold 11 on the processing block 10, and then the tapping drill bit is inserted into the processing hole 12 to perform tapping operation on the raw material to be processed. During the tapping operation, the tapping drill bit needs to be sprayed with water to cool down.

[0046] Step 6: After the tapping is completed, the third hydraulic box 13 in the material-returning mechanism operates, and the third hydraulic box 13 operates to push the linkage rod 15, and the linkage rod 15 then drives the material-returning block 29 to press down through the transmission shaft 16, and presses the processed raw material embedded in the processing hole 12 back to the lifting frame 8;

[0047] Step 7: After the processed raw materials are pressed back onto the lifting rack 8, the feeding mechanism operates again to drag the next raw material to be processed into the processing mechanism. The raw materials to be processed pushed into the processing mechanism again will push the processed raw materials out of the lifting rack 8 and fall into the receiving box;

[0048] Step eight: The waste generated when tapping the raw material to be processed will fall into the waste hole 26 on the waste discharge mechanism, and the waste will be discharged from the waste pipe 27 through the waste hole 26.

[0049] In summary, the conical workpiece tapping device of this embodiment, when in use, places the original conical workpiece to be processed on the feed rack 9, and the feed rack 9 transports the raw material to be processed to the feeding mechanism through the continuous vibration of the vibration motor. When the raw material to be processed is transported to the feeding mechanism, the raw material to be processed is pushed under the raw material clamping plate 24, and then the propulsion cylinder 20 on the mounting table 19 operates to push the feeding structure into the processing mechanism for processing through the pushing column. After the raw material to be processed is pushed into the processing mechanism, the first hydraulic box 4 and the second hydraulic box 5 operate to lift the first hydraulic column 6 and the second hydraulic column 7, and the first hydraulic column 6 and the second hydraulic column 7 are lifted upward, thereby driving the lifting frame 8 to rise from the inside of the first processing frame 2 and the second processing frame 3, and the lifting frame 8 rises. When the material to be processed is pushed into the lifting rack 8, it will drive the raw material to be processed that is pushed into the lifting rack 8 to rise. In the process of the lifting rack 8 lifting the raw material to be processed, the propulsion cylinder 20 operates to retract the pushing column, thereby driving the feeding mechanism to retract from the processing mechanism. In the process of the feeding mechanism retracting, the lifting cylinder 23 arranged in the clamping plate fixing frame 22 operates to lift the raw material clamping plate 24 through the pushing column, so that the raw material to be processed falls into the lifting rack 8. After the raw material to be processed falls into the lifting rack 8, it can be lifted by the lifting rack 8. The lifting rack 8 is lifted to lift the raw material to be processed and clamp it into the processing hole 12 inside the processing mold 11 on the processing block 10. Then the tapping drill bit is inserted into the processing hole 12 to perform tapping operation on the raw material to be processed. During the tapping operation, it is necessary to spray the tapping drill bit with water to cool it down. After the tapping is completed. The third hydraulic box 13 in the material return mechanism operates, and the third hydraulic box 13 operates to push the linkage rod 15, and the linkage rod 15 then drives the unloading block 29 to press down through the transmission shaft 16, and presses the processed raw material embedded in the processing hole 12 back onto the lifting rack 8. After the processed raw material is pressed back onto the lifting rack 8, the feeding mechanism operates again to drag the next raw material to be processed into the processing mechanism. The raw material to be processed that is pushed into the processing mechanism again will push the processed raw material out of the lifting rack 8 and fall into the material receiving box. The waste generated when tapping the raw material to be processed will fall into the waste hole 26 on the waste discharge mechanism, and the waste will be discharged from the waste pipe 27 through the waste hole 26.

A method for processing a tapered workpiece, characterized in that: Using the tapered workpiece tapping device as claimed in any one of claims 1 to 7 comprises the following steps: Step 1: placing the original conical workpiece to be processed on the feed rack (9), and the feed rack (9) conveys the raw material to be processed to the feeding mechanism through the continuous vibration of the vibration motor; Step 2: When the raw material to be processed is transported to the feeding mechanism, the raw material to be processed is pushed under the raw material clamping plate (24), and then the propulsion cylinder (20) on the mounting table (19) operates to push the feeding structure into the processing mechanism through the pushing column for processing; Step 3: After the raw material to be processed is pushed into the processing mechanism, the first hydraulic box (4) and the second hydraulic box (5) operate to lift the first hydraulic column (6) and the second hydraulic column (7). The first hydraulic column (6) and the second hydraulic column (7) are lifted upward, thereby driving the lifting frame (8) to rise from the inside of the first processing frame (2) and the second processing frame (3). When the lifting frame (8) is lifted, it will drive the raw material to be processed pushed into the lifting frame (8) to rise; Step 4: When the lifting rack (8) is lifting the raw material to be processed, the propulsion cylinder (20) operates to retract the push column, thereby driving the feeding mechanism to retract from the processing mechanism. During the retraction of the feeding mechanism, the lifting cylinder (23) arranged in the clamping plate fixing frame (22) operates to lift the raw material clamping plate (24) through the push column, so that the raw material to be processed falls into the lifting rack (8). After the raw material to be processed falls into the lifting rack (8), it can be lifted by the lifting rack (8); Step 5: The lifting frame (8) is raised to lift the raw material to be processed and inserted into the processing hole (12) inside the processing mold (11) on the processing block (10); the tapping drill bit is inserted into the processing hole (12) to perform tapping operation on the raw material to be processed. During the tapping operation, the tapping drill bit needs to be sprayed with water to cool it down; Step 6: After the tapping is completed, the third hydraulic box (13) in the material-returning mechanism is operated, and the third hydraulic box (13) is operated to push the linkage rod (15), and the linkage rod (15) then drives the material-returning block (29) to press down through the transmission shaft (16), so as to press the processed raw material embedded in the processing hole (12) back to the lifting frame (8); Step 7: After the processed raw material is pressed back onto the lifting rack (8), the feeding mechanism operates again to drag the next raw material to be processed into the processing mechanism. The raw material to be processed pushed into the processing mechanism again will push the processed raw material out of the lifting rack (8) and fall into the receiving box; Step eight: The waste generated when tapping the raw material to be processed will fall into the waste hole (26) on the waste discharge mechanism, and the waste will be discharged from the waste pipe (27) through the waste hole (26).
