Description

Technical Field

[0001] The invention relates to the technical field of tapping machines, and in particular to a high-precision tapping machine based on clamp processing. Background Art

[0002] An anchor is an anchoring tool installed at the end of the prestressed tendon and can always keep the prestressed tendon in an anchored state during the tensioning process of the prestressed tendon. Among them, the clip-type anchor is used for tensioning prestressed steel strands. It is mainly composed of anchors and clips. It mainly relies on the retraction of the tensioned steel bars to drive the clips to clamp the steel bars and then anchor them. The importance of tapping in the manufacture of anchor clips lies in that it directly affects the fixing effect and service life of the clips. If the quality of tapping is not good, such as unclear or damaged threads, it may cause the bolts or screws to fail to be firmly fixed on the clips, thereby affecting the stability and safety of the entire structure. Therefore, in the tapping process, each link needs to be strictly controlled to ensure the quality and accuracy of the thread.

[0003] The existing clamps are mostly clamped by radial force through a clamping mechanism during the tapping process. In order to achieve automatic feeding, the bottom is usually in a suspended state. During the tap descending tapping process, since the clamp is a truncated cone with an upper area smaller than the lower area, the bottom of the clamp lacks support. When the clamping mechanism is loose, the clamp is easy to loosen and deviate during the tapping process, affecting the tapping accuracy of the clamp or even detaching from the fixture. If the clamping mechanism is clamped too tightly, it will cause indentations on the surface of the clamp, affecting the appearance and quality of the clamp. In addition, since the tapping depth of the clamp is deep, the tap will produce chips during the tapping process. When the chips are not discharged in time in the hole and accumulate, it is easy to increase the friction between the tap and the chips, thereby causing the tap to get stuck, resulting in damage to the tap and the clamp. In severe cases, it will cause the tap to break, which has certain adverse effects on people's use process. In order to address the deficiencies of the prior art, a high-precision tapping machine based on clamp processing is proposed. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, a discharge device is provided, and when the tapping clip to be tapped falls to the top of the discharge device, the coolant is filtered through the filter screen, so that the coolant passes through the filter screen into the interior of the operation panel and is circulated through the water pump inside the operation panel, while the chips and the cooling pipe are discharged through the inclined surface of the guide plate, thereby realizing the filtering and recycling of the coolant.

[0019] 2. In the present invention, when the bottom support block rises to the inside of the discharge port, the bottom of the clamp to be tapped is supported, and the clamp to be tapped is clamped by the first clamping block and the second clamping block. The shape of the clamp to be tapped is utilized to clamp the clamp to be tapped more firmly, thereby preventing the clamp to be tapped from loosening and deviating during the process of the tap head descending and ascending to tap, thereby affecting the tapping accuracy of the clamp to be tapped.

[0020] 3. In the present invention, a torque sensor is provided. When the torque sensor detects that the torque force between the clamping iron block and the torque sensor is too large, the torque sensor controls the electromagnet to stop working through an electrical signal, causing the electromagnet to lose its magnetism instantly. The clamping iron block falls into the movable groove under the influence of gravity, and the tap head inside the chuck shank stops rotating, the connecting shaft idles, and then stops working, so as to avoid the tap head being stuck and the tapping machine body continuing to control the tap head to rotate and press down, resulting in the breakage of the tap head and damage to the clamping piece to be tapped.

[0021] 4. In the present invention, the coolant of the cooling tube cools the tap head through the sleeve, so as to avoid splashing of coolant and debris during the rotation of the tap head, thereby making the working environment cleaner. At the same time, it is convenient for the coolant to flow into the hole of the clamping piece to be tapped, so that the chips in the hole of the clamping piece to be tapped flow out with the coolant, thereby avoiding the chips from accumulating in the hole, which leads to an increase in the friction between the tap and the chips, causing the tap head to get stuck, and affecting the tapping quality.

[0022] 5. In the present invention, a limiting swivel is used to limit and support the lower end of the clamping rod to avoid the clamping rod being too long, which causes the clamping rod and the tap head to shake when rotating, so that the tapping of the tap head at the lower end of the clamping rod is more stable, thereby improving the tapping effect and accuracy of the tap head.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 - Figure 4 As shown, a high-precision tapping machine based on clip processing includes a processing machine 1, a tapping assembly 2 is arranged on the top of the processing machine 1, a clamping device 3 is fixedly installed on the left side of the top of the processing machine 1, a clip 5 to be tapped is placed inside the clamping device 3, and a support assembly 4 is arranged on the left side inside the processing machine 1.

[0035] like Figure 2 - Figure 3As shown, the processing machine 1 includes a support frame 11, a workbench 12 is fixedly installed on the top of the support frame 11, an operation panel 13 is fixedly installed on the right side of the top of the workbench 12, a tapping machine body 14 is fixedly installed on the left side of the top of the workbench 12, the output end of the tapping machine body 14 is fixedly connected to the top of the connecting shaft 21, a discharge port 16 is opened on the left side of the workbench 12, and the discharge port 16 is located below the tapping assembly 2, an operation panel 13 is fixedly connected to the left side inside the support frame 11, a discharge device 17 is fixedly connected to the top of the operation panel 13, a water pump is arranged inside the operation panel 13, and a cooling pipe 15 is fixedly connected to one side of the water pump, and one end of the cooling pipe 15 is connected to the liquid outlet 2101.

[0036] The cooling tube 15 is connected to the liquid outlet 2101. During the tapping process of the clamp 5 to be tapped, the sleeve 29 is pressed on the top of the first clamping block 32 and the second clamping block 36, and covers the top of the clamp 5 to be tapped, so that the coolant of the cooling tube 15 cools the tap head 25 through the sleeve 29, avoiding the splashing of the coolant and debris during the rotation of the tap head 25. At the same time, it is convenient for the coolant to flow into the hole of the clamp 5 to be tapped, so that the chips in the hole of the clamp 5 to be tapped flow out with the coolant, avoiding the chips from accumulating in the hole, resulting in an increase in the friction between the tap and the chips, and causing the tap head 25 to get stuck, thereby affecting the tapping quality.

[0037] Embodiment 2, as Figure 1 - Figure 3 , Figure 7 - Fig. 9 As shown, a high-precision tapping machine based on clamp processing is provided, wherein the clamping device 3 includes a fixed plate 31, the fixed plate 31 is fixedly mounted on the left side of the top of the workbench 12, a blanking port 33 is provided inside the fixed plate 31, and the position of the blanking port 33 corresponds to the position of the discharge port 16, a first clamping block 32 is fixedly mounted on one side of the top of the fixed plate 31, and movable grooves 34 are provided on both sides of the inner side of one end of the fixed plate 31 away from the first clamping block 32, a sliding frame 35 is slidably mounted on the top of the fixed plate 31, the sliding frame 35 is slidably mounted inside the movable groove 34, and a second clamping block 36 is fixedly mounted on the top of the sliding frame 35, a clamping cylinder 37 is fixedly connected to the side of the fixed plate 31 away from the first clamping block 32, one end of the clamping cylinder 37 is connected to one side of the sliding frame 35, and a groove corresponding to the clamp 5 to be tapped is provided between the first clamping block 32 and the second clamping block 36.

[0038] like Figure 3As shown, the discharging device 17 includes a guide plate 171, which is fixedly installed on the top of the operation panel 13, and limit frames 174 are fixedly installed on both sides of the right end of the guide plate 171. The limit frame 174 has a limit groove 173 inside. The limit frame 174 is fixedly installed on the bottom of the workbench 12, and a support plate 175 is fixedly connected between the limit frames 174 at both ends. A pushing cylinder 176 is fixedly installed on the right side of the support plate 175, and a pushing plate 177 is fixedly connected to the left side of the pushing cylinder 176. A wiping cotton 178 is fixedly connected to the bottom of the pushing plate 177.

[0039] The push cylinder 176 is used to control the movement of the push plate 177. When the bottom support block 41 drops to the lower end of the support plate 175, the push cylinder 176 controls the movement of the push plate 177, so that the push plate 177 pushes the clip 5 to be tapped on the top of the bottom support block 41 to fall to the top of the filter screen 172, and when the push plate 177 moves, the top of the bottom support block 41 is pushed and wiped by the wiping cotton 178, and the chips on the top of the bottom support block 41 are pushed out by the wiping cotton 178 to prevent the chips from staying on the top of the bottom support block 41, causing the clip 5 to be tapped to be placed on the top of the bottom support block 41 and tilt.

[0040] The bottom surface of the material guide plate 171 is inclined, and the left side of the material guide plate 171 is lower than the right side of the material guide plate 171 . A filter screen 172 is fixedly connected to the inside of the right side of the material guide plate 171 , and the filter screen 172 is located on the top of the operation panel 13 .

[0041] By setting up the discharge device 17, when the tapping clip 5 that has been tapped falls to the top of the discharge device 17, the coolant is filtered through the filter screen 172, so that the coolant enters the interior of the operation panel 13 through the filter screen 172 and is circulated through the water pump inside the operation panel 13, while the chips and the cooling pipe 15 are discharged through the inclined surface of the guide plate 171.

[0042] like Figure 8 and Fig. 9 As shown, the support assembly 4 includes a bottom support block 41, and connecting frames 42 are fixedly installed on both sides of the bottom of the bottom support block 41, and the connecting frames 42 are slidably installed inside the limiting groove 173, and one end of the connecting frames 42 on both sides is fixedly installed with a support rod 43, and the lower ends of the support rods 43 at both ends are provided with a fixing groove 44 on the side away from the bottom support block 41, and the inside of the fixing groove 44 is fixedly connected with a fixed rack 48, and a bidirectional motor 45 is fixedly installed at the bottom of the workbench 12, and a rotating shaft 46 is arranged inside the bidirectional motor 45, and the outer surfaces of both ends of the rotating shaft 46 are fixedly sleeved with driving gears 47, and the outer surface of the driving gear 47 is meshed with one side of the fixed rack 48, and the support rod 43 is movably sleeved inside the workbench 12, and the bottom support block 41 is embedded at the bottom of the discharge port 16.

[0043] The driving gears 47 at both ends of the rotating shaft 46 are controlled to rotate by the bidirectional motor 45, so that the support rod 43 is lifted and lowered inside the workbench 12, and then the bottom support block 41 is lifted and lowered inside the discharge port 16. When the bottom support block 41 rises to the inside of the discharge port 16, the bottom of the clamp 5 to be tapped is supported to avoid the lack of support at the bottom of the clamp 5 to be tapped during the tap head 25 descending for tapping, resulting in the clamp 5 to be tapped being loosened and deviated during the tapping process, thereby affecting the tapping accuracy of the clamp 5 to be tapped.

[0044] like Fig. 9 As shown, the bottom support block 41 includes a support frame 411, a water leakage groove 412 is provided on the top of the support frame 411, and the wiping cotton 178 is slidably installed on the upper surface of the support frame 411. A slag discharge groove 413 is provided at the bottom of the support frame 411, and a fixed frame 414 is fixedly connected to the lower end of the slag discharge groove 413. The middle part of the fixed frame 414 is movably sleeved with a bottom rod 417, and the top of the bottom rod 417 is fixedly connected to a movable block 415. The top of the movable block 415 is rotatable. A pressing ball 416 is installed, and the pressing ball 416 is movably sleeved on the top of the support pad frame 411. Limiting rods 418 are fixedly installed around the bottom of the movable block 415. The limiting rods 418 are movably sleeved inside the fixed frame 414. A movable spring 419 is movably sleeved on the outer surface of the limiting rod 418. The bottom of the movable block 415 is located on both sides of the limiting rod 418 and a protective plate 421 is fixedly installed. The protective plate 421 is movably sleeved inside the fixed frame 414.

[0045] By utilizing the drain groove 412 on the top of the support cushion frame 411, the coolant and part of the chips flow into the inside of the slag discharge groove 413 through the drain groove 412 and fall into the inside of the discharge device 17. The coolant flows into the inside of the operation panel 13 through the filter screen 172 to achieve recycling. In addition, the pressing ball 416 rotates on the top of the movable block 415. When the tap head 25 taps the cooling pipe 15, it will contact the top of the pressing ball 416. As the tap head 25 descends, the movable spring 419 is compressed, the bottom rod 417 and the limit rod 418 move inside the fixed frame 414, and the movable block 415 descends to the inside of the support cushion frame 411. At this time, the pressing ball 416 is used to prevent the tap head 25 from descending and interfering with the top of the support cushion frame 411. The bottom of the tap head 25 is protected by the rolling of the pressing ball 416 to prevent damage to the bottom of the tap head 25.

[0047] The chuck shank 23 is well known to those skilled in the art, and the clamping rod 24 is fixed by an internal chuck structure. The chuck is a cylindrical component with a taper, and the shank of the tool is inserted into the chuck. When the chuck is subjected to axial pressure, its internal elastic structure will deform, thereby tightly clamping the clamping rod 24. The specific structure of the chuck shank 23 is not the main innovation of the present application, and will not be elaborated on here.

[0048] The limiting swivel 2100 is used to limit and support the lower end of the clamping rod 24 to prevent the clamping rod 24 from being too long, which would cause the clamping rod 24 and the tap head 25 to shake when rotating, so that the tap head 25 at the lower end of the clamping rod 24 can tap more smoothly, thereby improving the tapping effect and accuracy of the tap head 25.

[0052] When installing, the clamping block 233 is inserted into the interior of the support block 217 by using the inclined surfaces on the upper and lower sides of the clamping block 233, and the clamping ball 218 at the upper end of the support block 217 is moved outward by using the inclined surface on the upper end of the clamping block 233. When the clamping block 233 passes the top of the support block 217, the hydraulic telescopic rod 213 is extended, causing the pressing sleeve 214 to descend and be sleeved on the top of the support block 217. The inclined surface of the tapered groove 215 is used to push the clamping ball 218 to move inward, and the clamping ball 218 is clamped at the bottom of the clamping block 233 to clamp the chuck handle 23. When disassembling, the hydraulic telescopic rod 213 is contracted, and the pressing sleeve 214 moves out of the outer surface of the support block 217. At this time, the chuck handle 23 is pulled downward, and the inclined surface at the lower end of the clamping block 233 is used to push the clamping ball 218 to move outward, completing the disassembly between the chuck handle 23 and the connecting shaft 21.

[0053] In addition, by utilizing the functions of the torque sensor 220 and the electromagnet 219, when the torque sensor 220 detects the torque force when the clamping iron block 236 rotates, when the tap head 25 is tapping, a jam occurs, and the tap head 25 stops rotating. At this time, the fixed sleeve 211 drives the torque sensor 220 to rotate, and the torque force between the clamping iron block 236 and the torque sensor 220 is too large. At this time, the torque sensor 220 controls the electromagnet 219 to stop working through an electrical signal, causing the electromagnet 219 to lose its magnetism instantly. At this time, the clamping iron block 236 falls into the inside of the movable groove 235 under the influence of gravity, and the tap head 25 inside the chuck shank 23 no longer rotates, the connecting shaft 21 idles, and then stops working, to avoid the tap head 25 being stuck, and the tapping machine body 14 continues to control the tap head 25 to rotate and press down, resulting in the breakage of the tap head 25 and the damage of the clamping piece 5 to be tapped.

[0054] It should be noted that the present invention is a high-precision tapping machine based on clamp processing. During installation, the clamping block 233 is inserted into the interior of the support block 217, and the clamping ball 218 at the upper end of the support block 217 is moved outward by utilizing the inclined surface at the upper end of the clamping block 233. When the clamping block 233 passes the top of the support block 217, the hydraulic telescopic rod 213 is extended to make the pressing sleeve 214 descend and be sleeved on the top of the support block 217. The inclined surface of the conical groove 215 is utilized to push the clamping ball 218 to move inward, and the clamping ball 218 is clamped at the bottom of the clamping block 233 to clamp the chuck tool handle 23. Subsequently, the electromagnet 219 performs the operation. During operation, the electromagnet 219 generates magnetism, which absorbs the clamping iron block 236, causing the clamping iron block 236 to rise in the movable groove 235 and be clamped in the inside of the clamping groove 221 to complete the fixation. During disassembly, the hydraulic telescopic rod 213 contracts, and the pressing sleeve 214 moves out of the outer surface of the support block 217. The electromagnet 219 stops working and loses its magnetism. The clamping iron block 236 falls into the inside of the movable groove 235 under the influence of gravity and moves out of the inside of the clamping groove 221. At this time, the chuck handle 23 is pulled downward, and the inclined surface at the lower end of the clamping block 233 is used to push the clamping ball 218 to move outward to complete the disassembly between the chuck handle 23 and the connecting shaft 21.

[0055] When in use, the clamping piece 5 to be tapped is sent to the top of the fixed plate 31 by the automatic feeding device. At this time, the clamping cylinder 37 is extended to make the sliding frame 35 move inside the moving groove 34. The second clamping block 36 pushes the clamping piece 5 to be tapped to move to one side of the first clamping block 32 and fall into the inside of the blanking opening 33. The bottom of the clamping piece 5 to be tapped is supported by the bottom support block 41. The second clamping block 36 pushes the clamping piece 5 to be tapped to move to the side of the first clamping block 32, and the clamping piece 5 to be tapped is clamped by the first clamping block 32 and the second clamping block 36.

[0056] The tapping machine body 14 descends and controls the connection shaft 21 to rotate. The tap head 25 descends to the inside of the clamping piece 5 to be tapped. The sleeve 29 is pressed on the top of the first clamping block 32 and the second clamping block 36 and covers the top of the clamping piece 5 to be tapped. The water pump works to pass the coolant inside the operation panel 13 through the cooling pipe 15 from the inside of the liquid outlet 2101 into the sleeve 29. The coolant cools the tap head 25 through the sleeve 29. As the tap head 25 moves in the tapping position, the tap head 25 is cooled. The inside of the clip 5 rotates and descends to tap. At this time, the connecting shaft 21 descends, and the limiting ring 22 presses the top of the extrusion spring 2102, so that the extrusion spring 2102 is gradually compressed. When the tap head 25 taps the lower end of the clip 5 to be tapped, the bottom of the tap head 25 presses the top of the pressing ball 416. At the same time, the pressing movable block 415 descends inside the support cushion frame 411, and the bottom rod 417 and the limiting rod 418 descend inside the fixing frame 414.

[0057] After the tapping of the tapping clamp 5 is completed, the tapping machine body 14 controls the connecting shaft 21 to rotate in the opposite direction, and the ascending tap head 25 moves out of the interior of the tapping clamp 5, and the squeezing spring 2102 is reset. Subsequently, the bidirectional motor 45 controls the driving gear 47 to rotate through the rotating shaft 46, and the fixed rack 48 is meshed with the driving gear 47 to make the support rod 43 descend inside the workbench 12, and the bottom support block 41 moves out of the bottom of the discharge port 16, pushing the cylinder 176 to work, and controlling the pushing plate 177 to move on the top of the supporting pad frame 411, and the pushing plate 177 pushes the tapping clamp 5 on the top of the supporting pad frame 411 to make it fall to the top of the discharge device 17, and at the same time, when the wiping cotton 178 moves on the top of the bottom support block 41 , wipe the top of the support pad frame 411 to keep the top of the support pad frame 411 clean, and avoid the clip 5 to be tapped from being tilted when placed on the top of the support pad frame 411. The clip 5 to be tapped that falls into the discharge device 17 is filtered through the filter screen 172 to allow the coolant to pass through the filter screen 172 and enter the interior of the operating panel 13, and is circulated through the water pump inside the operating panel 13. The chips and the clip 5 to be tapped are discharged through the inclined surface of the guide plate 171, and then the bidirectional motor 45 controls the driving gear 47 to rotate in the opposite direction, causing the support rod 43 to rise, and the bottom support block 41 rises to the inside of the discharge port 16 to support the next clip 5 to be tapped.
