Description

Technical Field

[0001] This invention belongs to the field of bolt manufacturing and processing technology, specifically a bolt thread burr removal device and its usage method. Background Technology

[0002] In the machining industry, screws and bolts, widely used in aerospace, shipbuilding, automotive, and agricultural machinery, are processed in numerous specifications and in large quantities. Some categories of products used in aviation and aerospace, as well as national military standards, require the machining of fuse holes, but explicitly prohibit secondary threading. This makes burr removal after machining fuse holes difficult, and for particularly small products, machining is generally impossible.

[0003] Existing deburring methods mostly involve wrench backing and manual filing. Both methods require manual operation and do not remove burrs completely, failing to achieve high-precision deburring results. Some methods use fluid polishing and electrolytic polishing, but these methods can cause damage to the bolts during deburring. For example, fluid polishing grinds non-burr areas while removing burrs, affecting the nut's fit accuracy. Similarly, electrolytic polishing corrodes non-burr areas while removing burrs, also affecting the nut's fit accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a bolt thread burr removal device and its usage method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bolt thread burr removal device, comprising a clamping and conveying mechanism, a burr removal mechanism, an ultrasonic device, a barbed bolt, and a main body. The ultrasonic device is disposed at the bottom of the main body, the clamping and conveying mechanism is fixedly installed on the top of the ultrasonic device, the burr removal mechanism is disposed at the top of the clamping and conveying mechanism, and the barbed bolt is engaged with the inner wall of the clamping and conveying mechanism.

[0006] The clamping and conveying mechanism includes a first sliding plate, which is slidably connected to the inner wall of the main body. A rotating component is fixedly connected to the bottom of the first sliding plate. A second sliding plate is rotatably connected to the bottom of the rotating component, and both sides of the second sliding plate are slidably connected to the inner wall of the main body. A movable base is fixedly connected to the bottom of the second sliding plate. A sliding groove is formed on the inner wall of the main body. There are two movable bases and two sliding grooves. The outer wall of the movable base is slidably connected to the inner wall of the sliding groove. A conveying component is threadedly connected to the inner wall of the movable base. A clamping component is fixedly connected to the bottom of the second sliding plate, and there are two clamping components. A finished product outlet is formed on the outer wall of the main body.

[0007] The rotating assembly includes a second hollow turntable, which is rotatably connected to a second sliding plate. A hollow connecting cylinder is fixedly connected to the top of the second hollow turntable, and a first hollow turntable is fixedly connected to the top of the hollow connecting cylinder.

[0008] The clamping assembly includes a first telescopic cylinder, which is fixedly connected to the top of the second hollow turntable. A steel wire is fixedly connected to the output end of the first telescopic cylinder, and the number of steel wires is set to multiple. A merging platform is fixedly connected to the outer wall of the hollow connecting cylinder. A limiting cylinder is fixedly connected to the inner wall of the first hollow turntable. A limiter is fixedly connected to the top of the first hollow turntable, and the number of limiting cylinders and limiters is set to multiple. A clamping rod is slidably connected to the inner wall of the limiter. The steel wire is fixedly connected to the clamping rod by passing through the merging platform, the limiting cylinder, and the limiter.

[0009] The above structure serves to clamp the bolt. With the clamping assembly in the open state, the barbed bolt is engaged above the slot platform. The slot platform can be replaced with any size that matches the tail of the barbed bolt. Then, the first telescopic cylinder is activated. The first telescopic cylinder operates to release multiple steel wires at the output end. The steel wires pass through the closing platform, limiters, and limit cylinders to release the clamping rod. The springs in the multiple limiters press the clamping rod inward together, causing the barbed bolt to be stuck in the center of the first hollow turntable.

[0010] As a further technical solution of the present invention, a rotating motor is fixedly connected to the bottom of the first sliding plate, and a transmission spur gear is fixedly connected to the output shaft of the rotating motor, and the teeth of the transmission spur gear mesh with the teeth of the second hollow turntable.

[0011] As a further technical solution of the present invention, a hydraulic lifter is fixedly connected to the inner wall of the main body, and a slot platform is engaged at the output end of the hydraulic lifter. The slot platform is engaged with the barbed bolt by penetrating the hollow connecting cylinder through the hydraulic lifter.

[0012] The above structure serves as an auxiliary clamping mechanism. The clamping and conveying mechanism is located on the far left of the equipment. The hydraulic lifter pushes the slot platform to the top in the hollow connecting cylinder.

[0013] As a further technical solution of the present invention, the conveying assembly includes a conveying motor, which is fixedly installed on the inner wall of the main body. The output end of the conveying motor is fixedly connected to a transmission helical gear, and the teeth of the transmission helical gear mesh with a driven helical gear.

[0014] As a further technical solution of the present invention, the conveying assembly includes a screw rod, which is rotatably connected to the inner wall of the main body, and the outer wall of the screw rod is threadedly connected to the inner wall of the movable base. The number of screw rods is set to two, and a transmission belt is connected between the outer walls of the two screw rods. The outer wall of one of the screw rods is fixedly connected to the inner wall of the driven helical gear.

[0015] The above structure serves the function of conveying and operating. When the conveyor motor is started, the output shaft of the conveyor motor drives the driven helical gear to rotate through the transmission helical gear. The screw rod fixed on the driven helical gear also rotates accordingly. Due to the connection of the transmission belt, the two screw rods rotate together to the right, causing the clamping and conveying mechanism fixed on the moving base to slide to the right along the slide groove.

[0016] As a further technical solution of the present invention, the burr removal mechanism includes a screw head deburring component and a screw body deburring component, both of which are fixedly connected to the inner wall of the main body.

[0017] As a further technical solution of the present invention, the screw head deburring assembly includes a second telescopic cylinder, which is fixedly connected to the inner wall of the main body, and an inverted triangular file is fixedly connected to the output end of the second telescopic cylinder.

[0018] The above structure achieves the effect of deburring the bolt head. The second telescopic cylinder and the rotating motor are activated. The output shaft of the rotating motor drives the second hollow turntable to rotate through the transmission spur gear. The spiked bolt also rotates. The output end of the second telescopic cylinder presses down to press the inverted triangular file onto the top of the spiked bolt.

[0019] As a further technical solution of the present invention, the screw body deburring assembly includes a driven uniform speed gear, which is rotatably connected to the inner wall of the main body. A uniform speed motor is fixedly connected to the inner wall of the main body. The output shaft of the uniform speed motor is fixedly connected to a transmission uniform speed gear, and the teeth of the transmission uniform speed gear mesh with the teeth of the driven uniform speed gear. A third telescopic cylinder is fixedly connected to the bottom of the driven uniform speed gear. A rotary cylinder is fixedly connected to the output end of the third telescopic cylinder. A hard brush head is fixedly connected to the output end of the rotary cylinder.

[0020] The above structure achieves the effect of deburring the bolt body. The third telescopic cylinder, the rotary cylinder, and the constant speed motor are activated. The output end of the constant speed motor drives the driven constant speed gear to rotate through the transmission constant speed gear, causing the third telescopic cylinder, which is fixed on the driven constant speed gear, to rotate along the periphery of the burred bolt. The third telescopic cylinder and the rotary cylinder rotate simultaneously, causing the hard bristle brush head to perform deburring treatment around the burred bolt.

[0021] As a further technical solution of the present invention, the ultrasonic device includes an ultrasonic box, which is disposed at the bottom of the main body, a drop switch opening is provided on the top of the ultrasonic box, and a high-precision outlet is provided on the outer wall of the ultrasonic box.

[0022] The above structure enables high-precision deburring of bolts, achieving a better deburring effect. When performing high-precision deburring on burred bolts, the drop switch is in the open state. The clamping assembly is released, and the semi-finished product falls from the hollow connecting cylinder into the ultrasonic chamber for high-precision deburring. After completion, it is taken out from the high-quality product outlet. When high-precision deburring of burred bolts is not required, the drop switch is in the closed state, and the finished product falls above the drop switch and is taken out from the finished product outlet.

[0023] A method of using a bolt thread burr removal device includes the following steps:

[0024] S1. During operation, the clamping and conveying mechanism is located on the far left of the equipment. The hydraulic lifter pushes the slot platform to the top in the hollow connecting cylinder, and the clamping assembly is in the open state. The barbed bolt is clamped on the top of the slot platform. The slot platform can be replaced with any size that is the same as the tail of the barbed bolt. Then, the first telescopic cylinder is activated. The first telescopic cylinder releases multiple steel wires at the output end. The steel wires pass through the platform, limiters, and limit cylinder to release the clamping rod. The springs in the multiple limiters press the clamping rod inward together, so that the barbed bolt is clamped in the center of the first hollow turntable. Then, the hydraulic lifter is activated to lower the slot platform to the initial position.

[0025] S2. Start the second telescopic cylinder and the rotating motor. The output shaft of the rotating motor drives the second hollow turntable to rotate via the transmission spur gear. The barbed bolt also rotates. The output end of the second telescopic cylinder presses down to press the inverted triangular file onto the top of the barbed bolt, deburring the head of the barbed bolt. After the deburring is completed, start the conveyor motor. The output shaft of the conveyor motor drives the driven helical gear to rotate via the transmission helical gear. The spiral rod fixed on the driven helical gear also rotates. Due to the connection of the transmission belt, the two spiral rods rotate to the right together, causing the clamping and conveying mechanism fixed on the moving base to slide to the right along the slide groove, and finally slide to the bottom of the deburring assembly.

[0026] S3. Start the third telescopic cylinder, the rotary cylinder, and the constant speed motor. The output end of the constant speed motor drives the driven constant speed gear to rotate through the transmission constant speed gear, causing the third telescopic cylinder, which is fixed on the driven constant speed gear, to rotate along the periphery of the barbed bolt. The third telescopic cylinder and the rotary cylinder rotate simultaneously, causing the hard bristle brush head to deburr the barbed bolt around it. After the deburring is completed, the conveying assembly continues to run, conveying the clamping conveying mechanism to the top of the drop switch port.

[0027] S4. When high-precision deburring of the barbed bolts is required, the drop switch is in the open state, the clamping assembly is released, and the semi-finished product falls from the hollow connecting cylinder into the ultrasonic chamber for high-precision deburring. After completion, it is taken out from the high-precision product outlet. When high-precision deburring of the barbed bolts is not required, the drop switch is in the closed state, the finished product falls above the drop switch and is taken out from the finished product outlet.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. This invention uses a combination of steel wires and telescopic cylinders to clamp bolts with multiple clamping heads, which stabilizes rotation and transports the bolts in subsequent operations. The barbed bolt is clamped above the clamping platform, which can be replaced with any size that matches the tail of the barbed bolt. Then, the first telescopic cylinder is activated, which releases multiple steel wires at the output end. The steel wires pass through the clamping platform, limiters, and limit cylinders to release the clamping rods. The springs in the multiple limiters press the clamping rods inward together, so that the barbed bolt is clamped in the center of the first hollow turntable.

[0030] 2. This invention uses multiple cylinders and motors to comprehensively remove burrs from the details of the bolt head, body, and threads. It offers two deburring options: finished product and high-quality product. The third telescopic cylinder, rotary cylinder, and constant-speed motor are activated. The output of the constant-speed motor drives the driven constant-speed gear to rotate via a transmission gear. This causes the third telescopic cylinder, fixed to the driven constant-speed gear, to rotate around the burr-laden bolt. Simultaneous rotation of the third telescopic cylinder and the rotary cylinder allows the hard-bristled brush head to deburr the bolt. After deburring, the conveying assembly continues to operate, transporting the bolt to the area above the drop switch. Attached Figure Description

[0045] The clamping assembly 17 includes a first telescopic cylinder 171, which is fixedly connected to the top of the second hollow turntable 123. A steel wire 173 is fixedly connected to the output end of the first telescopic cylinder 171, and the number of steel wires 173 is set to be multiple. A merging platform 176 is fixedly connected to the outer wall of the hollow connecting cylinder 122. A limiting cylinder 175 is fixedly connected to the inner wall of the first hollow turntable 121. A limiter 174 is fixedly connected to the top of the first hollow turntable 121, and the number of limiting cylinders 175 and limiters 174 is set to be multiple. A clamping rod 172 is slidably connected to the inner wall of the limiter 174. The steel wire 173 is fixedly connected to the clamping rod 172 by penetrating the merging platform 176, the limiting cylinder 175 and the limiter 174.

[0046] During operation, the clamping and conveying mechanism 1 is located on the far left of the equipment. The hydraulic lift 127 pushes the slot platform 126 to the top in the hollow connecting cylinder 122, and the clamping assembly 17 is in the open state, clamping the barbed bolt 4 above the slot platform 126. The slot platform 126 can be replaced with any size that is the same as the tail of the barbed bolt 4. Then, the first telescopic cylinder 171 is activated. The first telescopic cylinder 171 releases multiple steel wires 173 at the output end. The steel wires 173 pass through the closing platform 176, the limiter 174 and the limit cylinder 175 to release the clamping rod 172. The springs in the multiple limiters 174 squeeze the clamping rod 172 inward together, so that the barbed bolt 4 is clamped in the center of the first hollow turntable 121. Then, the hydraulic lift 127 is activated to lower the slot platform 126 to the initial position.

[0047] like Figure 3 and Figure 5As shown, a rotary motor 125 is fixedly connected to the bottom of the first sliding plate 11. A transmission spur gear 124 is fixedly connected to the output shaft of the rotary motor 125, and the teeth of the transmission spur gear 124 mesh with the teeth of the second hollow turntable 123. A hydraulic lifter 127 is fixedly connected to the inner wall of the main body. A slot platform 126 is engaged at the output end of the hydraulic lifter 127, and the slot platform 126 is engaged with the barbed bolt 4 through the hollow connecting cylinder 122 via the hydraulic lifter 127. The conveying assembly 15 includes a conveying motor 151, which is fixedly installed on the inner wall of the main body. A transmission helical gear 152 is fixedly connected to the output end of the conveying motor 151, and the teeth of the transmission helical gear 152 mesh with a driven helical gear 153. The conveying assembly 15 includes a screw rod 155, which is rotatably connected to the inner wall of the main body. The outer wall of the screw rod 155 is threadedly connected to the inner wall of the movable base 14. The number of screw rods 155 is set to two, and a transmission belt 154 is connected between the outer walls of the two screw rods 155. The outer wall of one of the screw rods 155 is fixedly connected to the inner wall of the driven helical gear 153.

[0048] Start the conveyor motor 151. The output shaft of the conveyor motor 151 drives the driven helical gear 153 to rotate via the transmission helical gear 152. The spiral rod 155 fixed on the driven helical gear 153 also rotates. Due to the connection of the transmission belt 154, the two spiral rods 155 rotate to the right together, causing the clamping conveyor mechanism 1 fixed on the movable base 14 to slide to the right along the slide groove 16, and finally slide to the bottom of the screw body deburring assembly 22. After the screw body is processed, the conveyor assembly 15 continues to run to transport the clamping conveyor mechanism 1 to the top of the drop switch port 33.

[0049] like Figure 4 As shown, the deburring mechanism 2 includes a screw head deburring assembly 21 and a screw body deburring assembly 22. Both the screw head deburring assembly 21 and the screw body deburring assembly 22 are fixedly connected to the inner wall of the main body. The screw head deburring assembly 21 includes a second telescopic cylinder 211, which is fixedly connected to the inner wall of the main body. An inverted triangular file 212 is fixedly connected to the output end of the second telescopic cylinder 211. The screw body deburring assembly 22 includes a driven uniform speed gear 224, which rotates to connect... A constant speed motor 226 is fixedly connected to the inner wall of the main body.

[0050] The second telescopic cylinder 211 and the rotary motor 125 are activated. The output shaft of the rotary motor 125 drives the second hollow turntable 123 to rotate via the transmission spur gear 124. The barbed bolt 4 also rotates accordingly. The output end of the second telescopic cylinder 211 presses down to press the inverted triangular file 212 onto the top of the barbed bolt 4, deburring the head of the barbed bolt 4. The third telescopic cylinder 221, the rotary cylinder 222, and the constant speed motor 226 are activated. The output end of the constant speed motor 226 drives the driven constant speed gear 224 to rotate via the transmission constant speed gear 225, causing the third telescopic cylinder 221, which is fixed on the driven constant speed gear 224, to rotate around the barbed bolt 4.

[0052] When high-precision deburring of the barbed bolt 4 is required, the drop switch port 33 is in the open state, the clamping assembly 17 is released, and the semi-finished product falls from the hollow connecting cylinder 122 into the ultrasonic box 32 to perform high-precision deburring. After completion, it is taken out from the high-precision product outlet 31. When high-precision deburring of the barbed bolt 4 is not required, the drop switch port 33 is in the closed state, the finished product falls above the drop switch port 33 and is taken out from the finished product outlet 18.

[0053] A method of using a bolt thread burr removal device includes the following steps:

[0054] S1. During operation, the clamping and conveying mechanism 1 is located on the far left of the equipment. The hydraulic lifter 127 pushes the slot platform 126 to the top in the hollow connecting cylinder 122. The clamping assembly 17 is in the open state, and the barbed bolt 4 is clamped above the slot platform 126. The slot platform 126 can be replaced with any size that is the same as the tail of the barbed bolt 4. Then, the first telescopic cylinder 171 is activated. The first telescopic cylinder 171 operates to release multiple steel wires 173 at the output end. The steel wires 173 pass through the closing platform 176, the limiter 174 and the limit cylinder 175 to release the clamping rod 172. The springs in the multiple limiters 174 squeeze the clamping rod 172 inward together, so that the barbed bolt 4 is clamped in the center of the first hollow turntable 121. Then, the hydraulic lifter 127 is activated to lower the slot platform 126 to the initial position.

[0055] S2. Start the second telescopic cylinder 211 and the rotating motor 125. The output shaft of the rotating motor 125 drives the second hollow turntable 123 to rotate via the transmission spur gear 124. The barbed bolt 4 also rotates. The output end of the second telescopic cylinder 211 presses down to press the inverted triangular file 212 onto the top of the barbed bolt 4 to deburr the head of the barbed bolt 4. After the deburring is completed, start the conveyor motor 151. The output shaft of the conveyor motor 151 drives the driven helical gear 153 to rotate via the transmission helical gear 152. The spiral rod 155 fixed on the driven helical gear 153 also rotates. Due to the connection of the transmission belt 154, the two spiral rods 155 rotate to the right together, causing the clamping and conveying mechanism 1 fixed on the moving base 14 to slide to the right along the slide groove 16, and finally slide to the bottom of the deburring assembly 22.

[0056] S3. Start the third telescopic cylinder 221, the rotary cylinder 222 and the constant speed motor 226. The output end of the constant speed motor 226 drives the driven constant speed gear 224 to rotate through the transmission constant speed gear 225, so that the third telescopic cylinder 221 fixed on the driven constant speed gear 224 rotates along the periphery of the barbed bolt 4. The third telescopic cylinder 221 and the rotary cylinder 222 rotate at the same time, so that the hard bristle brush head 223 performs deburring treatment around the barbed bolt 4. After the treatment is completed, the conveying assembly 15 continues to run to convey the clamping conveying mechanism 1 to the top of the drop switch port 33.

[0057] S4. When high-precision deburring of the barbed bolt 4 is required, the drop switch port 33 is in the open state, the clamping assembly 17 is released, and the semi-finished product falls from the hollow connecting cylinder 122 into the ultrasonic box 32 to perform high-precision deburring. After completion, it is taken out from the high-precision product outlet 31. When high-precision deburring of the barbed bolt 4 is not required, the drop switch port 33 is in the closed state, the finished product falls above the drop switch port 33 and is taken out from the finished product outlet 18.

10. A method of using the bolt thread burr removal device according to any one of claims 1-9, characterized in that: Includes the following steps: S1. During operation, the clamping and conveying mechanism (1) is located on the far left of the equipment. The hydraulic lifter (127) pushes the slot platform (126) to the top in the hollow connecting cylinder (122). The clamping assembly (17) is in the open state, and the barbed bolt (4) is clamped on the top of the slot platform (126). The slot platform (126) can be replaced with any size that is the same as the tail size of the barbed bolt (4). Then, the first telescopic cylinder (171) is started. The cylinder (171) operates to release multiple steel wires (173) at the output end. The steel wires (173) pass through the merging platform (176), limiter (174) and limit cylinder (175) to release the clamping rod (172). The springs in the multiple limiters (174) press the clamping rod (172) inward together, so that the barbed bolt (4) is stuck in the center of the first hollow turntable (121). Then the hydraulic lifter (127) is started to lower the slot platform (126) to the initial position. S2. Start the second telescopic cylinder (211) and the rotating motor (125). The output shaft of the rotating motor (125) drives the second hollow turntable (123) to rotate via the transmission spur gear (124). The barbed bolt (4) also rotates. The output end of the second telescopic cylinder (211) presses down to press the inverted triangular file (212) onto the top of the barbed bolt (4) to deburr the head of the barbed bolt (4). After the deburring is completed, start the conveyor motor (151). The output shaft of the conveyor motor (151) drives the driven helical gear (153) to rotate via the transmission helical gear (152). The spiral rod (155) fixed on the driven helical gear (153) also rotates. Due to the connection of the transmission belt (154), the two spiral rods (155) rotate to the right together, causing the clamping conveyor mechanism (1) fixed on the moving base (14) to slide to the right along the slide groove (16) and finally slide to the bottom of the deburring assembly (22). S3. Start the third telescopic cylinder (221), the rotary cylinder (222) and the constant speed motor (226). The output end of the constant speed motor (226) drives the driven constant speed gear (224) to rotate through the transmission constant speed gear (225), so that the third telescopic cylinder (221) fixed on the driven constant speed gear (224) rotates along the periphery of the barbed bolt (4). The third telescopic cylinder (221) and the rotary cylinder (222) rotate at the same time, so that the hard bristle brush head (223) performs deburring treatment around the barbed bolt (4). After the treatment is completed, the conveying assembly (15) continues to run to convey the clamping conveying mechanism (1) to the top of the drop switch port (33). S4. When it is necessary to perform high-precision deburring on the barbed bolt (4), the drop switch (33) is in the open state, the clamping assembly (17) is released, and the semi-finished product falls from the hollow connecting cylinder (122) into the ultrasonic box (32) to perform high-precision deburring on the semi-finished product. After completion, it is taken out from the high-precision product outlet (31). When it is not necessary to perform high-precision deburring on the barbed bolt (4), the drop switch (33) is in the closed state, the finished product falls above the drop switch (33) and is taken out from the finished product outlet (18).
