Description

Technical Field

[0001] This invention belongs to the field of tapping and milling technology, and more specifically, it relates to a dual-head tapping and milling integrated equipment and its usage method. Background Technology

[0002] Internal thread tapping equipment is a key tool for machining internal threads on workpieces. It is mainly used to quickly and accurately cut and form thread structures in pre-drilled holes. Compared with manual tapping, this equipment can significantly improve efficiency and ensure thread accuracy, and is especially suitable for mass production scenarios such as automotive parts and electronic components. After tapping, the workpiece usually needs to be milled.

[0003] The following problems still exist in the tapping and milling of workpieces:

[0004] 1. Generally, it does not have the function of dual-head tapping. When both ends of the workpiece need to be tapped, the workpiece needs to be processed twice, which affects the tapping efficiency of the workpiece. Moreover, the workpiece cannot be automatically milled after dual-head tapping.

[0005] 2. The clamping structure cannot automatically adjust according to the workpiece's processing status, and tapping operations can be performed even when the workpiece is not accurately placed in the positioning area, which can easily lead to processing errors in the workpiece.

[0006] 3. It is inconvenient for staff to intermittently check whether the tapped workpiece meets the machining accuracy requirements, and it cannot assist staff in changing the tapping milling cutter. Summary of the Invention

[0014] In at least some embodiments, the replacement auxiliary component includes: an inclined mounting plate, a V-shaped guide bracket, and a low-speed motor b; the inclined mounting plate is fixedly mounted on the front side of the tapping and milling seat; the V-shaped guide bracket is fixedly mounted on the top of the inclined mounting plate, and a circular hole is provided on the V-shaped guide bracket, the diameter of which is the same as the diameter of the workpiece; the low-speed motor b is fixedly mounted on the inclined mounting plate, and the low-speed motor b is electrically connected to the control panel.

[0015] In at least some embodiments, the replacement auxiliary component further includes: a circular mounting rod, a circular threaded tube, and mounting blocks; the circular mounting rod is fixedly mounted on the output shaft of the low-speed motor b; the circular threaded tube is rotatably mounted on the outside of the circular mounting rod, and the thread on the circular threaded tube matches the thread on the tapped workpiece; two mounting blocks are provided, and the two mounting blocks are fixedly mounted on the outer wall of the circular mounting rod, and the two mounting blocks are also inserted into the circular threaded tube.

[0017] In another aspect, this disclosure provides a method of using a dual-head tapping and milling integrated machine, comprising the following steps:

[0018] 1) Secure the tapping and milling base with bolts, and then install the external robot arm in front of the tapping and milling base;

[0019] 2) The workpiece to be tapped is placed in the positioning slot by an external robotic arm;

[0020] 3) Press the corresponding button on the control panel to extend the output shafts of the four electric telescopic rods a;

[0021] 4) When the four electric telescopic rods a do not work after the button on the control panel is pressed, the operator should manually adjust the position of the workpiece and then press the button on the control panel again.

[0022] 5) Wait for the workpiece to finish tapping, then press the corresponding button on the control panel to retract the output shafts of the four electric telescopic rods a, and then remove the tapped workpiece by the external robotic arm.

[0023] 6) When it is necessary to check the tapping accuracy of the workpiece, insert the tapped workpiece into the round hole on the V-shaped guide frame, then start the low-speed motor b through the control panel, and then the operator holds the workpiece and slowly moves the workpiece downward.

[0024] 7) When the staff hears an alarm sound from the control panel, they should promptly replace the two tapping and milling cutters.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. When the output shafts of the four electric telescopic rods a extend, the two rectangular mounting plates move inward; when the output shafts of the four electric telescopic rods a retract after extending, the two rectangular mounting plates move outward; when the two low-speed motors a are working, the output shafts of the two low-speed motors a drive the two tapping milling cutters to rotate, realizing simultaneous tapping of the workpiece from both ends, improving the tapping efficiency of the workpiece; when the tapped workpiece contacts the milling cutting edges on the two tapping milling cutters, the two tapping milling cutters can perform automatic double-head milling processing on the tapped workpiece.

[0027] 2. The V-shaped positioning seat and positioning slot of this invention serve to position the workpiece to be tapped, ensuring that different workpieces remain in the same position after placement. When the output shaft of the electric telescopic rod b extends, the arc-shaped pressing block moves downward, automatically pressing the workpiece to be tapped. When the output shaft of the electric telescopic rod b retracts after extending, the arc-shaped pressing block moves upward, creating a larger gap between the arc-shaped pressing block and the tapped workpiece. This facilitates the external robotic arm in gripping the tapped workpiece and also makes it easier for the external robotic arm to place the workpiece to be tapped into the positioning slot.

[0028] Furthermore, when the output shafts of the four electric telescopic rods a extend, the arc-shaped pressing plate can press the feedback button a first; when the feedback button a is pressed, the control panel controls the output shaft of the electric telescopic rod b to automatically extend, ensuring that the arc-shaped pressing block can press the workpiece before tapping; when the output shafts of the four electric telescopic rods a retract after extending, the arc-shaped pressing plate can press the feedback button a again; when the feedback button a is pressed again, the control panel controls the output shaft of the electric telescopic rod b to automatically retract, enabling the electric telescopic rod b to work automatically according to the processing status of the workpiece; when the workpiece to be tapped is accurately placed in the positioning slot, under the weight of the workpiece itself... The two hollow pressing tubes can be pushed downwards, causing the two feedback buttons b to be pressed. When the workpiece to be tapped is not accurately placed in the positioning slot, the workpiece cannot push the two hollow pressing tubes downwards simultaneously, causing one or both feedback buttons b to be unpressed. When both feedback buttons b are pressed, the four electric telescopic rods a will work when the operator presses the corresponding button on the control panel. When one or both feedback buttons b are unpressed, the four electric telescopic rods a will not work when the operator presses the corresponding button on the control panel, ensuring that no processing errors occur on the workpiece.

[0029] 3. The V-shaped guide frame of this invention guides the workpiece after tapping, so that the workpiece can be concentric with the circular threaded tube; when the low-speed motor b is working and the operator slowly moves the workpiece downward, the top of the circular threaded tube can be screwed into the workpiece.

[0030] In addition, when the workpiece after tapping is not very accurate, the resistance between the top of the circular threaded tube and the workpiece is large, which causes the corresponding return spring to be compressed. When one of the return springs is compressed, the mounting block can press the corresponding feedback button c, which will activate the alarm on the control panel, so that the staff can know that the two tapping milling cutters need to be replaced.

Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0051] Example: Please refer to Figures 1 to 10 As shown: This invention provides a dual-head tapping and milling integrated machine for processing workpiece 300; it includes: a tapping and milling part 100, a positioning and clamping part 200, and a replacement auxiliary part 400; the positioning and clamping part 200 is installed on the tapping and milling part 100, and the workpiece 300 to be tapped is disposed on the positioning and clamping part 200; the positioning and clamping part 200 is used to position the workpiece 300 to be tapped, and also to clamp the workpiece 300 to be tapped; the replacement auxiliary part 400 is installed on the front side of the tapping and milling part 100, and is used to detect the tapping accuracy of the workpiece 300; a control panel 500 is installed on the replacement auxiliary part 400, and the control panel 500 is used to control the tapping and milling part 100, the positioning and clamping part 200, and the replacement auxiliary part 400.

[0052] In this embodiment of the disclosure, such as Figure 1 As shown, the tapping and milling component 100 includes: a tapping and milling base 101, an electric telescopic rod a102, and a rectangular mounting plate 103; four electric telescopic rods a102 are provided, and the four electric telescopic rods a102 are fixedly mounted on the tapping and milling base 101, and the four electric telescopic rods a102 are electrically connected to the control panel 500; two rectangular mounting plates 103 are provided, and the two rectangular mounting plates 103 are fixedly mounted on the output shafts of the four electric telescopic rods a102; the tapping and milling component 100 also includes: a low-speed motor a104 and a tapping and milling cutter 105; two low-speed motors a104 are provided, and the two low-speed motors a104 are fixedly mounted on the two rectangular mounting plates 103, and the two low-speed motors a104 are electrically connected to the control panel 500; two tapping and milling cutters 105 are provided, and the two tapping and milling cutters 105 are fixedly mounted on the output shafts of the two low-speed motors a104;

[0053] Its specific function is as follows: Since four electric telescopic rods a102 are fixedly installed on the tapping and milling seat 101, and two rectangular mounting plates 103 are fixedly installed on the output shafts of the four electric telescopic rods a102, when the output shafts of the four electric telescopic rods a102 extend, the two rectangular mounting plates 103 move inward; when the output shafts of the four electric telescopic rods a102 extend and retract, the two rectangular mounting plates 103 move outward; and since two low-speed motors a104 are fixedly installed on the two rectangular mounting plates 103... Furthermore, the two tapping milling cutters 105 are fixedly mounted on the output shafts of the two low-speed motors a104. When the two low-speed motors a104 are working, the output shafts of the two low-speed motors a104 drive the two tapping milling cutters 105 to rotate, realizing simultaneous tapping of the workpiece 300 from both ends, thus improving the tapping efficiency of the workpiece 300. When the tapped workpiece 300 contacts the milling cutting edge on the two tapping milling cutters 105, the two tapping milling cutters 105 can perform automatic milling of the tapped workpiece 300 from both ends.

[0054] In this embodiment of the disclosure, such as Figure 2 , Figure 3 and Figure 5 As shown, the positioning clamping component 200 includes: a V-shaped positioning seat 201, an L-shaped mounting bracket 202, and an electric telescopic rod b203; the V-shaped positioning seat 201 is fixedly installed on the top of the tapping and milling seat 101, and a positioning slot 2011 is provided on the V-shaped positioning seat 201; the L-shaped mounting bracket 202 is fixedly installed on the top of the V-shaped positioning seat 201; the electric telescopic rod b203 is fixedly installed on the L-shaped mounting bracket 202, and the electric telescopic rod b203 is electrically connected to the control panel 500; the positioning clamping component 200 also includes: an arc-shaped pressing block 204, a feedback button a205, and a triangular mounting bracket 206; the arc-shaped pressing block 204 is fixedly installed on the output shaft of the electric telescopic rod b203; the feedback button a205 is fixedly installed on the L-shaped mounting bracket 202, and the feedback button a205 is electrically connected to the control panel 500; the triangular mounting bracket 206 is fixedly installed on the left side. The rectangular mounting plate 103 is used for positioning and clamping components. The positioning and clamping components 200 also include: an arc-shaped pressing plate 207, feedback buttons b208, and hollow pressing tubes 209. The arc-shaped pressing plate 207 is fixedly installed on the front side of the triangular mounting bracket 206, and the front side of the arc-shaped pressing plate 207 contacts the L-shaped mounting bracket 202. There are two feedback buttons b208, and the two feedback buttons b208 are fixedly installed inside the tapping and milling base 101, and the two feedback buttons b208 are electrically connected to the control panel 500. There are two hollow pressing tubes 209, and the two hollow pressing tubes 209 are slidably installed on the tapping and milling base 101 and the V-shaped positioning base 201. The top ends of the two hollow pressing tubes 209 contact the workpiece 300 to be tapped, and the bottom ends of the two hollow pressing tubes 209 contact the two feedback buttons b208, and the two feedback buttons b208 are in a pressed state.

[0055] Its specific functions are as follows: Because the V-shaped positioning seat 201 is fixedly installed on the top of the tapping and milling seat 101, and the V-shaped positioning seat 201 has a positioning slot 2011, it positions the workpiece 300 to be tapped, ensuring that different workpieces 300 are always in the same position after placement; Furthermore, because the L-shaped mounting bracket 202 is fixedly installed on the top of the V-shaped positioning seat 201, and the electric telescopic rod b203 is fixedly installed on the L-shaped mounting bracket 202, and the arc-shaped pressing block 204 is fixedly installed on the input of the electric telescopic rod b203... On the output shaft, when the output shaft of the electric telescopic rod b203 extends, the arc-shaped pressing block 204 moves downward, so that the arc-shaped pressing block 204 automatically presses the workpiece 300 to be tapped; when the output shaft of the electric telescopic rod b203 extends and retracts, the arc-shaped pressing block 204 moves upward, so that a larger gap is created between the arc-shaped pressing block 204 and the tapped workpiece 300, which is beneficial for the external robot to grasp the tapped workpiece 300, and also makes it easier for the external robot to place the workpiece 300 to be tapped in the positioning slot 2011;

[0056] Furthermore, since the feedback button a205 is fixedly mounted on the L-shaped mounting bracket 202, and the triangular mounting bracket 206 is fixedly mounted on the rectangular mounting plate 103 on the left side, and the arc-shaped pressing plate 207 is fixedly mounted on the front side of the triangular mounting bracket 206, when the output shafts of the four electric telescopic rods a102 extend, the arc-shaped pressing plate 207 can press the feedback button a205 first; when the feedback button a205 is pressed, the control panel 500 controls the output shaft of the electric telescopic rod b203 to automatically extend, ensuring that the workpiece 300 is tapped. Previously, the arc-shaped pressing block 204 could press the workpiece 300 first; when the output shafts of the four electric telescopic rods a102 extended and retracted, the arc-shaped pressing plate 207 could press the feedback button a205 again; when the feedback button a205 was pressed again, the control panel 500 controlled the output shaft of the electric telescopic rod b203 to automatically retract, so that the electric telescopic rod b203 could work automatically according to the processing status of the workpiece 300; and because the hollow pressing tube 209 was slidably installed on the tapping and milling seat 101 and the V-shaped positioning seat 201, The top ends of the two hollow pressing tubes 209 are in contact with the workpiece 300 to be tapped, and the bottom ends of the two hollow pressing tubes 209 are in contact with the two feedback buttons b208. When the workpiece 300 to be tapped is accurately placed in the positioning slot 2011, the weight of the workpiece 300 itself can push the two hollow pressing tubes 209 downward, so that the two feedback buttons b208 are in the pressed state. When the workpiece 300 to be tapped is not accurately placed in the positioning slot 2011, the workpiece 300 cannot push the two hollow pressing tubes 209 downward. The pressure tube 209 moves downwards simultaneously, so that one or two feedback buttons b208 are in an unpressed state; when both feedback buttons b208 are in the pressed state, the four electric telescopic rods a102 will work when the operator presses the corresponding button on the control panel 500; when one or two feedback buttons b208 are in the unpressed state, the four electric telescopic rods a102 will not work when the operator presses the corresponding button on the control panel 500, ensuring that the workpiece 300 will not have processing errors.

[0057] In this embodiment of the disclosure, such as Figure 6 , Figure 8 and Figure 10As shown, the replacement auxiliary component 400 includes: an inclined mounting plate 401, a V-shaped guide bracket 402, and a low-speed motor b403; the inclined mounting plate 401 is fixedly mounted on the front side of the tapping and milling seat 101; the V-shaped guide bracket 402 is fixedly mounted on the top of the inclined mounting plate 401, and a circular hole is provided on the V-shaped guide bracket 402, the diameter of which is the same as the diameter of the workpiece 300; the low-speed motor b403 is fixedly mounted on the inclined mounting plate 401, and is electrically connected to the control panel 500; the replacement auxiliary component 400 also includes: a circular mounting rod 404, a circular threaded tube 405, and a mounting block 406; the circular mounting rod 404 is fixedly mounted on the output shaft of the low-speed motor b403; the circular threaded tube 405 is rotatably mounted on the outside of the circular mounting rod 404, and the thread on the circular threaded tube 405 is aligned with the tapped workpiece. The threads on 300 are matched; there are two mounting blocks 406, which are fixedly installed on the outer wall of the circular mounting rod 404 and inserted into the circular threaded tube 405; the replacement auxiliary component 400 also includes: a feedback button c407, an arc-shaped reset rod 408, and a reset spring 409; there are two feedback buttons c407, which are fixedly installed inside the circular threaded tube 405 and electrically connected to the control panel 500; the arc-shaped reset rod 408 is fixedly installed on the circular threaded tube 405 and slidably connected to the mounting block 406; there are two reset springs 409, which are sleeved on the outside of the arc-shaped reset rod 408 and located on both sides of the mounting block 406;

[0058] Its specific functions are as follows: Since the V-shaped guide frame 402 is fixedly installed on the top of the inclined mounting plate 401, and the V-shaped guide frame 402 has a round hole with the same diameter as the workpiece 300, it guides the tapped workpiece 300 so that the tapped workpiece 300 can be concentric with the circular threaded tube 405; since the low-speed motor b403 is fixedly installed on the inclined mounting plate 401, and the thread on the circular threaded tube 405 matches the thread on the tapped workpiece 300, when the low-speed motor b403 is working and the operator slowly moves the tapped workpiece 300 downwards, the top end of the circular threaded tube 405 can be screwed into the workpiece 300.

[0059] Furthermore, since the arc-shaped reset rod 408 is fixedly installed on the circular threaded tube 405, and the two reset springs 409 are sleeved on the outside of the arc-shaped reset rod 408, and the two reset springs 409 are located on both sides of the mounting block 406, when the precision of the tapped workpiece 300 is not high, the resistance between the top of the circular threaded tube 405 and the workpiece 300 is large, causing the corresponding reset spring 409 to be compressed; and since the two feedback buttons c407 are fixedly installed inside the circular threaded tube 405, when one of the reset springs 409 is compressed, the mounting block 406 can press the corresponding feedback button c407, causing the alarm in the control panel 500 to work, so that the staff can know that the two tapping milling cutters 105 need to be replaced;

[0060] Among them, the rotation angle of the output shaft of the low-speed motor B403 needs to be controlled within a suitable angle range to ensure that the wires on the two feedback buttons C407 do not get tangled. After tapping, the workpieces are intermittently tested after a certain number of intervals, which serves as an auxiliary prompting function.

[0061] This invention provides a method for using a dual-head tapping and milling integrated machine, comprising the following steps:

[0062] 1) Secure the tapping and milling base 101 with bolts, and then install the external robot arm in front of the tapping and milling base 101;

[0063] 2) The workpiece 300 to be tapped is placed in the positioning slot 2011 by an external robotic arm;

[0064] 3) Press the corresponding button on the control panel 500 to extend the output shafts of the four electric telescopic rods a102;

[0065] 4) When the button on the control panel 500 is pressed and the four electric telescopic rods a102 do not work, the operator should manually adjust the position of the workpiece 300 and then press the button on the control panel 500 again.

[0066] 5) Wait for the workpiece 300 to finish tapping, then press the corresponding button on the control panel 500 to retract the output shaft of the four electric telescopic rods a102, and then remove the tapped workpiece 300 by the external robotic arm.

[0067] 6) When it is necessary to check the tapping accuracy of workpiece 300, insert the tapped workpiece 300 into the round hole on the V-shaped guide frame 402, then start the low-speed motor b403 through the control panel 500, and then the operator holds the workpiece 300 and slowly moves the workpiece 300 downward.

[0068] 7) When the staff hears the alarm sound from the control panel 500, the staff should promptly replace the two tapping and milling cutters 105.

[0069] The specific usage and function of this embodiment are as follows:

[0070] In use, the tapping and milling base 101 is first fixedly installed with bolts, and then an external robotic arm is installed in front of the tapping and milling base 101. The workpiece 300 to be tapped is placed in the positioning slot 2011 by the external robotic arm. Pressing the corresponding button on the control panel 500 causes the output shafts of the four electric telescopic rods a102 to extend. When the output shafts of the four electric telescopic rods a102 extend, the two rectangular mounting plates 103 move inward. When the output shafts of the four electric telescopic rods a102 retract after extending, the two rectangular mounting plates 103 move outward. When the two low-speed motors a104 are working, the output shafts of the two low-speed motors a104 drive the two tapping and milling cutters 105 to rotate, realizing the simultaneous tapping of the workpiece 300 from both ends. The tapping process improves the tapping efficiency of workpiece 300. When the tapped workpiece 300 contacts the milling edges on the two tapping milling cutters 105, the two tapping milling cutters 105 can perform double-head automatic milling on the tapped workpiece 300. When the output shaft of the four electric telescopic rods a102 extends, the arc-shaped pressing plate 207 can press the feedback button a205 first. When the feedback button a205 is pressed, the control panel 500 controls the output shaft of the electric telescopic rod b203 to automatically extend, ensuring that the arc-shaped pressing block 204 can press the workpiece 300 first before tapping. When the output shaft of the four electric telescopic rods a102 extends and retracts, the arc-shaped pressing plate 207 can press the feedback button a205 again first. When pressed again, the control panel 500 controls the output shaft of the electric telescopic rod b203 to automatically retract, enabling the electric telescopic rod b203 to work automatically according to the processing status of the workpiece 300. When the workpiece 300 to be tapped is accurately placed in the positioning slot 2011, the weight of the workpiece 300 itself can push the two hollow pressing tubes 209 downward, putting the two feedback buttons b208 in the pressed state. When the workpiece 300 to be tapped is not accurately placed in the positioning slot 2011, the workpiece 300 cannot push the two hollow pressing tubes 209 downward simultaneously, putting one or both feedback buttons b208 in the unpressed state. When both feedback buttons b208 are in the pressed state, the operator presses the control panel... When the corresponding button on the control panel 500 is pressed, the four electric telescopic rods a102 operate. When one or two feedback buttons b208 are not pressed, the four electric telescopic rods a102 do not operate when the operator presses the corresponding button on the control panel 500, ensuring that the workpiece 300 does not have processing errors. When the button on the control panel 500 is pressed and the four electric telescopic rods a102 do not operate, the operator manually adjusts the position of the workpiece 300 and then presses the button on the control panel 500 again. After the workpiece 300 has finished tapping, the corresponding button on the control panel 500 is pressed to retract the output shaft of the four electric telescopic rods a102, and then the tapped workpiece 300 is removed by an external robotic arm.When the tapping accuracy of workpiece 300 needs to be checked, the tapped workpiece 300 is inserted into the round hole on the V-shaped guide bracket 402. Then, the low-speed motor b403 is started via the control panel 500. The operator then grips the workpiece 300 and slowly moves it downwards. When the tapping accuracy of workpiece 300 is not high, the resistance between the top of the circular threaded tube 405 and the workpiece 300 is large, causing the corresponding return spring 409 to compress. When one of the return springs 409 is compressed, the mounting block 406 presses the corresponding feedback button c407, activating the alarm on the control panel 500. When the operator hears the alarm sound from the control panel 500, the operator promptly replaces the two tapping milling cutters 105.
