Therefore, the processing accuracy and quality requirements for automotive locking bolts are also increasing day by day, which requires high-precision and high-performance thread processing devices for automotive locking bolts to meet the production needs.

[0003] However, when the existing thread processing devices for automotive locking bolts are in use, it is not convenient to center and fix the bolts to be processed, and it is difficult to ensure that the central axis of the bolt coincides with the rotation axis of the processing device, resulting in the uniformity of thread processing being affected and eccentric threads occurring. Summary of the Invention

[0004] The purpose of the present invention is to provide a thread processing device for automotive locking bolts. By setting a fixing part, the problem that when the existing thread processing devices for automotive locking bolts are in use, it is not convenient to center and fix the bolts to be processed, and it is difficult to ensure that the central axis of the bolt coincides with the rotation axis of the processing device, resulting in the uniformity of thread processing being affected and eccentric threads occurring is solved.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a thread processing device for automotive locking bolts, including a bottom plate. Above the bottom plate is provided a bolt to be processed. It further includes:

[0007] A rotating part, which is arranged on the bottom plate and is used to drive the bolt to be processed to rotate; a fixing part, which is installed on the bottom plate and is used to fix the bolt to be processed; and a cleaning part, which is arranged on the top of the bottom plate and is used to clean during and after thread processing. Among them, after the bolt to be processed is fixed on the fixing part, the rotating part drives the fixing part to drive the bolt to be processed to rotate, and the cleaning part completes self-cleaning while performing thread processing.

[0008] Furthermore, the rotating part includes a bracket fixedly connected to the top of the bottom plate. A hollow sleeve is rotatably connected to the bracket. A first gear is fixedly connected to the outer wall of the hollow sleeve. A first rotating shaft is rotatably connected to the right side of the bracket. A power member is arranged on the bracket. Among them, two cylindrical grooves are opened on the bracket. The upper cylindrical groove penetrates the bracket for connecting the hollow sleeve. The left side of the first rotating shaft extends into the lower cylindrical groove on the bracket.

[0009] Furthermore, the fixing part includes a fixing component arranged on the hollow sleeve for fixing the bolt to be machined; and a transmission component arranged on the fixing component for transmitting power to the fixing component. By rotating the transmission component, the fixing component clamps and fixes the bolt to be machined.

[0010] Furthermore, the cleaning part includes a feeding component installed on the top of the bottom plate for generating a feeding motion to cooperate with the fixing part for thread machining; and a cleaning component arranged on the feeding component for cleaning the feeding component. The feeding motion generated by the cleaning component also serves as the power source for the cleaning motion of the cleaning component while machining the thread.

[0011] Furthermore, the fixing component includes a cylindrical shell fixedly connected to the right side of the hollow sleeve. A worm gear is rotatably connected to the inner wall of the cylindrical shell. A number of clamping pieces are arranged on the worm gear, and the number of clamping pieces is circumferentially arrayed on the worm gear. The cylindrical shell is formed by opening an annular groove in a hollow disc, and a part of its outer wall is cut to expose the annular groove for connecting with the transmission component. The worm gear is of a hollow design, and its inner wall is rotatably connected to the inner wall of the cylindrical shell.

[0012] Furthermore, the transmission component includes a rectangular shell communicatively arranged on the cylindrical shell. A worm is rotatably connected to the inner wall of the rectangular shell. A second rotating shaft penetrates through the worm, and the outer wall of the second rotating shaft is fixedly connected to the worm. The worm meshes with the worm gear, and by driving the worm and the worm gear, a number of clamping pieces clamp and center the bolt to be machined. The second rotating shaft is rotatably connected to the cylindrical shell.

[0013] Furthermore, the feeding component includes a support frame fixedly connected to the top of the bottom plate. A threaded rod is rotatably connected to the inner wall of the support frame, and the right side of the threaded rod extends outside the support frame. A sliding rod is fixedly connected to the inner wall of the support frame. Two sliding blocks are slidably connected to the support frame. A cutting piece is arranged on the front sliding block. The threaded rod threadedly penetrates through the front sliding block, and the sliding rod slidably penetrates through the rear sliding block. The two sliding blocks are mirror-symmetrically arranged on the support frame.

[0014] Furthermore, the cleaning component includes a cleaning brush fixedly connected between the two sliding blocks. The bottom of the cleaning brush contacts the support frame. Two dirt collection ports are opened on the support frame. A dirt collection box is placed on the top of the bottom plate. A large-volume inner cavity is designed in the support frame for storing the dirt collection box, and this inner cavity communicates with the two dirt collection ports. The cleaning brush moves with the feeding component and scrapes the debris on the support frame into the dirt collection box through the two dirt collection ports.

[0015] Further, the clamping member includes an arc-shaped groove formed in the worm gear. A cylindrical limiting rod is arranged in the arc-shaped groove, and the outer wall of the cylindrical limiting rod is in contact with the arc-shaped groove. A rectangular slider is fixedly connected to the right side of the cylindrical limiting rod, and a clamping plate is fixedly connected to the right side of the rectangular slider. A rectangular sliding groove is formed in the right side of the cylindrical shell, and the inner wall of the rectangular sliding groove is slidably connected to the rectangular slider. Among them, the mutually approaching sides of the clamping plates of several clamping members are all in close contact with the bolt to be processed, so that it is fixed on the fixing part.

[0016] Further, the power member includes a gear two fixedly connected to the first rotating shaft. The gear two is meshed with the gear one, and a first motor is fixedly connected to the bracket; and a cutting member. The cutting member includes a threading tool fixedly connected to the rear side of the slider located at the front side. A second motor is fixedly connected to the right side of the support frame, and the output shaft of the second motor is fixedly connected to the right extended portion of the threaded rod through a coupling. Among them, the first motor is fixedly connected to the cylindrical groove located at the lower side of the bracket, and its output shaft is fixedly connected to the part of the first rotating shaft extending into this cylindrical groove through a coupling. The tip of the threading tool is in contact with the thread groove being opened on the bolt to be processed for threading.

[0017] The present invention has the following beneficial effects:

[0018] (1) By setting the fixing part, when in use, the bolt to be processed is passed through the hollow sleeve and the cylindrical shell, and then the second rotating shaft is rotated by the knob on the second rotating shaft. The second rotating shaft drives the worm gear to rotate on the cylindrical shell through the worm, so that the arc-shaped groove on the cylindrical shell rotates accordingly. The arc-shaped groove presses the cylindrical limiting rod, and the cylindrical limiting rod drives the rectangular slider to move towards the bolt to be processed under the limitation of the rectangular sliding groove, thereby driving the clamping plate to move towards the bolt to be processed. That is, at this time, the clamping plates of several clamping members all approach the bolt to be processed until the bolt to be processed is clamped. Stop rotating the second rotating shaft and start threading. Start the first motor on the bracket. The first motor drives the gear two to rotate through the first rotating shaft. The gear two drives the hollow sleeve to rotate on the bracket through the gear one. The hollow sleeve drives the bolt to be processed thereon to rotate through the fixing part, so that during the clamping process, the bolt can be automatically centered, and the central axis of the bolt coincides with the rotation axis of the processing device, thereby ensuring the uniformity of threading and avoiding eccentric threads, laying a foundation for the tight fit of bolts and nuts in subsequent automobile assembly.

[0019] (2) In the present invention, by providing a cleaning part, when the bolt to be processed rotates, the second motor is started. The second motor drives the slider on the front side to move leftward through the threaded rod, so that the threading tool on it contacts the rotating bolt to be processed. Since the threading tool always makes a feeding movement to the right, the tool tip cuts threads on the outer wall of the bolt to be processed. At this time, the cleaning brush will also slide to the right, thus scraping the inner wall of the support frame until the debris is hung on the dirt collection port on the left side. The debris falls into the dirt collection box below due to gravity. At this time, the processing of the threads is also completed. Reversing the second rotating shaft can loosen the bolt to be processed by the fixing part, and then the bolt to be processed can be removed. Then, control the second motor to reverse to reset the cleaning brush, so as to clean the support frame again, so that the debris is discharged into the dirt collection box through the dirt collection port on the right side. Then, clean the dirt collection box regularly, which enables automatic cleaning of the debris on the support frame, avoids the accumulation of debris in the processing area, thus preventing the situation where debris flies and mixes between the processing parts, and ensures the cleanliness of the processing environment;

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The cleaning unit 3 includes a feeding assembly 31 and a cleaning assembly 32. The feeding assembly 31 is installed on the top of the bottom plate 111 and is used to generate a feeding motion to cooperate with the fixing unit 2 for thread machining. The cleaning assembly 32 is arranged on the feeding assembly 31 and is used to clean the feeding assembly 31. Among them, the feeding motion generated by the cleaning assembly 32 also serves as the power source for the cleaning motion of the cleaning assembly 32 while machining the thread. The feeding assembly 31 includes a support frame 311 fixedly connected to the top of the bottom plate 111. A threaded rod 312 is rotatably connected to the inner wall of the support frame 311. The right side of the threaded rod 312 extends outside the support frame 311. A sliding rod 313 is fixedly connected to the inner wall of the support frame 311.

Among them, the tip of the threading tool 315 is in contact with the thread groove being opened on the bolt 112 to be machined for threading. By providing the cleaning unit 3, the debris on the support frame 311 can be automatically cleaned, avoiding the accumulation of debris in the machining area, thereby preventing the situation of debris flying and mixing between the machining parts, and ensuring the cleanliness of the machining environment.

[0036] During use, the bolt 112 to be processed is passed through the hollow sleeve 114 and the cylindrical shell 211, and then the second rotating shaft 223 is rotated by turning the knob on the second rotating shaft 223. The second rotating shaft 223 drives the worm gear 212 to rotate on the cylindrical shell 211 through the worm 222. As a result, the arc-shaped groove 213 on the cylindrical shell 211 rotates accordingly. The arc-shaped groove 213 presses the cylindrical limiting rod 214, and the cylindrical limiting rod 214 drives the rectangular slider 215 to move towards the bolt 112 to be processed under the limitation of the rectangular sliding groove 217, thereby driving the clamping plate 216 to move towards the bolt 112 to be processed. That is, at this time, the clamping plates 216 of several clamping members all move closer to the bolt 112 to be processed until the bolt 112 to be processed is clamped. Then, stop rotating the second rotating shaft 223, and then start the thread processing. Start the first motor 118 on the bracket 113. The first motor 118 drives the second gear 117 to rotate through the first rotating shaft 116. The second gear 117 drives the hollow sleeve 114 to rotate on the bracket 113 through the first gear 115. The hollow sleeve 114 drives the bolt 112 to be processed thereon to rotate through the fixing part 2. At this time, start the second motor 316. The second motor 316 drives the front slider 314 to move leftward through the threaded rod 312, so that the threading tool 315 thereon contacts the rotating bolt 112 to be processed. Since the threading tool 315 always makes a feeding movement to the right, its cutting edge cuts a thread on the outer wall of the bolt 112 to be processed. At this time, the cleaning brush 321 will also slide to the right accordingly, thereby scraping the inner wall of the support frame 311 until the debris is hung on the left sewage collection port 322, and the debris falls into the lower sewage collection box 323 under the action of gravity. At this time, the thread processing is also completed. Reverse the second rotating shaft 223 to release the bolt 112 to be processed by the fixing part 2, and then the bolt 112 to be processed can be removed. Then, control the second motor 316 to reverse to reset the cleaning brush 321, so as to clean the support frame 311 again, so that the debris is discharged into the sewage collection box 323 through the right sewage collection port 322, and then clean the sewage collection box 323 regularly.
