Industrial overhead door transmission reel machining all-in-one machine

Abstract

The present application relates to the technical field of shaft processing, and discloses an industrial lifting door transmission reel processing all-in-one machine, which comprises a workbench and matched drilling and tapping assemblies. Through the cooperation of the blocking sleeve and the bristles, when the two enter the drilling hole together, the blocking sleeve can effectively constrain the bristles, avoid pushing the debris to the top of the drilling hole due to excessive dispersion in the insertion process, and reduce the accumulation of debris from the source. After the blocking sleeve moves down along the downhill section of the lifting slope, the bristles rotate at high speed under the action of the friction wheel and the friction plate. The originally bent bristles in the blocking sleeve are unfolded by centrifugal force and elasticity, tightly fit the inner wall of the drilling hole, and realize 360° dead angle-free cleaning. Even the small debris in the deep drilling hole can be completely removed. This design not only solves the problem of debris residue in the traditional cleaning method, but also avoids the possible damage to the hole wall caused by manual cleaning, reduces the processing defects such as tapping jamming and insufficient thread accuracy caused by debris.

Description

Technical Field

[0001] This invention belongs to the field of shaft processing technology, specifically, it relates to an integrated machine for processing the drive shaft of an industrial lifting door. Background Technology

[0002] In the manufacturing process of the drive roller of an industrial overhead door, drilling and tapping are critical steps. Because industrial overhead doors require automated control and safety monitoring, components such as position sensors and torque sensors are typically installed on the drive roller. The installation of these components necessitates pre-drilling precise mounting holes on the roller, and the drilling process forms the basic structure for these holes. Tapping, on the other hand, creates internal threads on the inner wall of the drilled holes, allowing for the secure fixing of sensors and other components using bolts or other connectors. This ensures stable operation during the high-speed rotation of the roller. Therefore, the quality of drilling and tapping directly affects the installation accuracy and operational reliability of the sensors and other components, thus impacting the overall performance of the industrial overhead door. The effectiveness of cleaning residual debris after drilling directly affects the quality of subsequent tapping and product performance. Currently, the industry commonly uses a simple method of directly inserting a brush into the drill hole to clean debris after drilling into transmission reel shafts. Existing brushes, when inserted into a drill hole, tend to spread out excessively due to their elasticity, causing debris from the inner wall of the hole to accumulate at the bottom. If this accumulated debris is not completely cleaned, it will be squeezed between the thread and the hole wall during subsequent tapping processes as the tap rotates and feeds. This not only accelerates tap wear and may even cause it to break, but also results in insufficient thread precision and a rough surface. In severe cases, thread seizing may occur, affecting the assembly accuracy and service life of the drive shaft, and consequently, adversely impacting the installation stability of components such as sensors.

[0003] In view of this, the present invention is proposed. Summary of the Invention

The side wall of the plane is provided with a friction plate, and the friction plate corresponds to the friction wheel installed on the side wall of the push rod, so that the brush bristles rotate in the borehole to clean up debris.

[0006] In a preferred embodiment of the present invention, the workbench is provided with four support legs at the bottom, and the bottom of adjacent support legs is provided with reinforcing ribs of different heights. The bottom of each support leg is provided with an adjusting rod for easy height adjustment by screwing it in. The bottom of the adjusting rod is provided with a pad, which is in the shape of a boss and has an anti-slip pad at the bottom.

[0007] In a preferred embodiment of the present invention, the drilling assembly and the tapping assembly are symmetrically distributed and mounted on the top of the workbench. A PLC controller is mounted on the workbench and is electrically connected to the drilling assembly and the tapping assembly. An indicator light is also mounted on the workbench and is connected to the PLC controller.

[0008] In a preferred embodiment of the present invention, a pair of slide rails are installed on the workbench, and a connecting frame is installed at the bottom of the pair of slide rails. The connecting frame is installed on an inclined surface opened on the surface of the workbench, and the inclined surface facilitates the cleaning of debris. Connecting seats are installed at both ends of the slide rails, and the connecting seats are bolted to the workbench. The slide rails and the sliding seats are slidably connected.

[0009] In a preferred embodiment of the present invention, a three-jaw chuck is rotatably mounted on each of the pair of slides. The three-jaw chuck is used to clamp the workpiece. A shifting motor is mounted on one of the slides. The output end of the shifting motor is connected to the corresponding three-jaw chuck. The shifting motor is used to drive the drill to rotate so that its opening faces downward, which facilitates the removal of debris by gravity. The other slide has a through hole to facilitate the installation of the workpiece. A threaded rod is mounted on the side wall of the slide with the shifting motor. The threaded rod passes through the other slide and a first nut and a second nut are rotatably mounted on the threaded rod. The first nut and the second nut are screwed and pressed against the side wall of the slide with the through hole. The threaded rod is used to adjust the gap between the pair of slides.

[0010] In a preferred embodiment of the present invention, an L-shaped bracket is installed on the side wall of the slide where the shifting motor is installed. A sliding sleeve is installed at the end of the L-shaped bracket. A lead screw shaft is screwed into the sliding sleeve. Fixed seats are rotatably installed at both ends of the lead screw shaft. The bottom of the fixed seats is welded to the worktable. A drive motor is installed on the side wall of one of the fixed seats. The output end of the drive motor is connected to the lead screw shaft.

[0011] In a preferred embodiment of the present invention, a sleeve is installed at the bottom of the bending frame, and a ball is embedded inside the sleeve. The ball is in contact with the first bracket, and a ball is provided at the bottom of the push rod. The bottom of the ball is in contact with the second bracket.

[0012] In a preferred embodiment of the present invention, a pair of limiting rods are installed at the bottom of the synchronization frame. The heights of the pair of limiting rods are different. A limiting plate is installed at the bottom of the pair of limiting rods. The diameter of the limiting plate is larger than the diameter of the limiting rod. A first bracket is sleeved on the outer limiting rod. The first bracket is connected to the bending frame. A second bracket is sleeved on the inner limiting rod. The second bracket is rotatably connected to the push rod.

[0013] In a preferred embodiment of the present invention, a compression spring is sleeved on the outer limiting rod, one end of the compression spring is engaged with the first bracket, and the other end of the compression spring is engaged with the bottom of the synchronization frame. A reset spring is sleeved on the inner limiting rod, one end of the reset spring is engaged with the second bracket, and the other end of the reset spring is engaged with the bottom of the synchronization frame.

[0014] In a preferred embodiment of the present invention, a slope is installed at the bottom of the plane. The slope is used to guide the bristles to move downward and the drill hole to separate, thereby facilitating the drill hole to rotate back to directly below the tapping assembly.

[0015] Compared with the prior art, the present invention has the following advantages: This invention utilizes the interplay between a barrier sleeve and brush bristles. When both enter the borehole together, the barrier sleeve effectively restrains the brush bristles, preventing them from excessively spreading and pushing debris to the top of the borehole during insertion. This reduces the risk of debris accumulation at the source. As the barrier sleeve descends along the slope, the brush bristles rotate at high speed under the action of the friction wheel and friction plate. The bristles, originally bent within the barrier sleeve, unfold using centrifugal force and elasticity, tightly adhering to the inner wall of the borehole, achieving 360° cleaning without dead angles. Even fine debris deep within the borehole can be thoroughly removed. This design solves the problem of debris residue in traditional cleaning methods and avoids scratches on the borehole wall that may be caused by manual cleaning. It also reduces processing defects such as tapping jamming and insufficient thread precision caused by debris. At the same time, the cleaned debris can fall smoothly through the gap between the brush bristles and the barrier sleeve. Combined with the guidance of the inclined surface of the worktable, this further ensures the cleanliness of the borehole interior, providing a stable processing foundation for subsequent tapping processes and significantly improving the product qualification rate and service life of the transmission reel.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] Example 1: like Figures 1 to 8 As shown, an integrated machine for processing the drive roller of an industrial lifting door includes a worktable 1 and a suitable drilling assembly 16 and tapping assembly 17.

[0021] A pair of slide blocks 14 for driving workpiece switching positions are slidable on the worktable 1; A timing frame 23 is installed on the side wall of the slide block 14. A blocking sleeve 2 is slidably arranged on the timing frame 23. A side plate 21 is installed on the side wall of the blocking sleeve 2, and a bending frame 211 is installed at the bottom of the side plate 21. The bottom of the bending frame 211 is slidably connected to the first guide rail 24 provided on the worktable 1. A positioning shaft 22 is slidably arranged on the timing frame 23. A brush bristle 221 is installed on the positioning shaft 22, and the brush bristle 221 corresponds to the blocking sleeve 2. A push rod 222 is installed at the bottom of the positioning shaft 22, and the push rod 222 is slidably connected to the second guide rail 25 provided on the worktable 1. The second guide rail 25 is provided with an insertion slope 251. The front half of the insertion slope 251 is used to guide the brush bristles 221 to be inserted into the barrier sleeve 2. The first guide rail 24 is provided with a lifting slope 241. The rear half of the insertion slope 251 and the lifting slope 241 are used to lift the barrier sleeve 2 and the brush bristles 221 into the borehole. The lower slope of the lifting slope 241 is used to guide the barrier sleeve 2 to move down, and the brush bristles 221 slide along the plane 252 on the insertion slope 251. The side wall of the plane 252 is provided with a friction plate 31, and the friction plate 31 corresponds to the friction wheel 3 installed on the side wall of the push rod 222, so that the brush bristles 221 rotate in the borehole to clean up debris.

[0022] like Figures 1 to 8 As shown in the specific embodiment, the workbench 1 has four support legs 11 installed at its bottom. Adjacent support legs 11 have reinforcing ribs 111 of different heights installed at their bottoms. Adjustment rods 112, which are screwed onto the bottom of each support leg 11 for easy height adjustment, are installed at the bottom of each adjustment rod 112. The adjustment rods 112 have pads 113 in the shape of bosses, and anti-slip pads 114 are provided at their bottoms. The levelness of the workbench 1 can be flexibly adjusted using the adjustment rods 112, the reinforcing ribs 111 improve overall stability, and the anti-slip pads 114 increase friction to prevent equipment slippage, ensuring the smoothness of the processing.

[0023] like Figures 1 to 8 As shown, the drilling assembly 16 and tapping assembly 17 are symmetrically distributed and mounted on the top of the worktable 1. A PLC controller 12 is mounted on the worktable 1, and the PLC controller 12 is electrically connected to the drilling assembly 16 and tapping assembly 17. An indicator light 121 is also mounted on the worktable 1, and the indicator light 121 is interconnected with the PLC controller 12. The above structure illustrates the layout and control method of the drilling and tapping assemblies. The symmetrical distribution facilitates workstation switching, the PLC controller 12 enables automated control, and the indicator light 121 provides real-time status feedback, improving the convenience of equipment operation and the accuracy of processing.

[0024] like Figures 1 to 8 As shown, a pair of slide rails 13 are further installed on the worktable 1. A connecting bracket 131 is installed at the bottom of the slide rails 13. The connecting bracket 131 is installed on an inclined surface on the surface of the worktable 1, and the inclined surface facilitates the cleaning of debris. Connecting seats 132 are installed at both ends of the slide rails 13, and the connecting seats 132 are bolted to the worktable 1. The slide rails 13 are slidably connected to the slide blocks 14. This section describes the installation structure of the slide rails 13. The slide rails 13 provide a stable sliding path for the slide blocks 14, the inclined surface facilitates the sliding of debris, and the connecting seats 132 ensure that the slide rails 13 are firmly installed, reducing vibration interference during processing and facilitating debris cleaning.

[0025] like Figures 1 to 8As shown, furthermore, a three-jaw chuck 141 is rotatably mounted on each of the pair of slides 14. The three-jaw chuck 141 is used to clamp the workpiece. A shifting motor 142 is mounted on one of the slides 14. The output end of the shifting motor 142 is connected to the corresponding three-jaw chuck 141. The shifting motor 142 is used to drive the drill to rotate so that its opening faces downward, which is convenient for cleaning debris by gravity. The other slide 14 has a through hole 143 to facilitate workpiece installation. A threaded rod 144 is mounted on the side wall of the slide 14 with the shifting motor 142. The threaded rod 144 is interconnected with the other slide 14, and a first nut 145 and a second nut 146 are rotatably mounted on the threaded rod 144. The first nut 145 and the second nut 146 are screwed and pressed against the side wall of the slide 14 with the through hole. The threaded rod 144 is used to adjust the gap between the pair of slides 14. This section introduces the functions of the slide block 14 and related components. The three-jaw chuck 141 firmly clamps the workpiece, the shifting motor 142 enables the workpiece to be flipped and uses gravity to remove chips, and the threaded rod 144 adjusts the spacing to adapt to different workpieces, thus improving the versatility of the equipment and the cleaning effect.

[0026] like Figures 1 to 8 As shown, furthermore, an L-shaped bracket 154 is installed on the side wall of the slide 14, which is equipped with the shifting motor 142. A sliding sleeve 153 is installed at the end of the L-shaped bracket 154. A lead screw shaft 15 is screwed into the sliding sleeve 153. Fixed seats 151 are rotatably installed at both ends of the lead screw shaft 15. The bottom of the fixed seats 151 is welded to the worktable 1. A drive motor 152 is installed on the side wall of one of the fixed seats 151. The output end of the drive motor 152 is connected to the lead screw shaft 15. The drive motor 152 drives the lead screw shaft 15 to rotate, which drives the slide 14 to move smoothly through the sliding sleeve 153. The fixed seat 151 ensures the stable operation of the lead screw shaft 15, realizing the precise transfer of the workpiece between different workstations and improving processing efficiency.

[0027] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a sleeve 212 is installed at the bottom of the bending frame 211, and a ball bearing 213 is embedded inside the sleeve 212. The ball bearing 213 is in contact with the first support 233. A ball bearing 223 is provided at the bottom of the push rod 222, and the bottom of the ball bearing 223 is in contact with the second support 235. The ball bearing 213 and the ball bearing 223 reduce the friction when the bending frame 211 and the push rod 222 move, making the movement of the components smoother, reducing equipment wear, and extending service life.

[0028] like Figures 1 to 8As shown, in a specific embodiment, a pair of limiting rods 231 are installed at the bottom of the synchronization frame 23. The heights of the pair of limiting rods 231 are different. A limiting plate 232 is installed at the bottom of the pair of limiting rods 231. The diameter of the limiting plate 232 is larger than the diameter of the limiting rod 231. A first bracket 233 is sleeved on the outer limiting rod 231. The first bracket 233 and the bending frame 211 are connected to each other. A second bracket 235 is sleeved on the inner limiting rod 231. The second bracket 235 is rotatably connected to the push rod 222. A compression spring 234 is sleeved on the outer limiting rod 231. One end of the compression spring 234 is engaged with the first bracket 233, and the other end is engaged with the bottom of the synchronization frame 23. A return spring 236 is sleeved on the inner limiting rod 231. One end of the return spring 236 is engaged with the second bracket 235, and the other end is engaged with the bottom of the synchronization frame 23. Limiting rod 231 and limiting plate 232 restrict the movement range of the components, while compression spring 234 and return spring 236 enable automatic reset of the components, ensuring precise and controllable movement of the barrier sleeve 2 and brush bristles 221, and improving the reliability of the cleaning structure.

[0029] like Figures 1 to 8 As shown, furthermore, a slope 253 is installed at the bottom of the plane 252. The slope 253 is used to guide the brush bristles 221 to move downward and separate from the drill hole, thereby facilitating the re-rotation of the drill hole to directly below the tapping assembly 17. By guiding the brush bristles 221 to separate from the drill hole, it is convenient for the subsequent workpiece to rotate to the tapping station, ensuring the smoothness of the process connection.

[0030] The implementation principle of the integrated machine for processing industrial lifting door drive rollers according to the present invention is as follows: When the industrial lifting door drive roller processing integrated machine is in operation, the worktable 1 is first placed horizontally and stably by adjusting the adjusting rod 112 at the bottom of the support leg 11 and cooperating with the anti-slip pad 114 at the bottom of the pad block 113. The reinforcing rib 111 further enhances the load-bearing capacity of the overall structure. During operation, according to the length of the workpiece on the drive roller, the first nut 145 and the second nut 146 on the threaded rod 144 are rotated to adjust the gap between the pair of slide blocks 14. Then, one end of the workpiece is passed through the through hole 143 of one of the slide blocks 14, and the other end is clamped and fixed by the three-jaw chuck 141. The PLC controller 12 serves as the core control unit, coordinating the orderly operation of the drilling assembly 16, the tapping assembly 17, and various drive components. The indicator light 121 provides real-time feedback on the working status of the equipment. When the equipment is started, the drive motor 152 drives the lead screw shaft 15 to rotate. Through the screwing action of the sliding sleeve 153 and the lead screw shaft 15, the slide block 14, which is equipped with the L-shaped bracket 154, slides along the slide rail 13, thereby moving the workpiece to below the drilling assembly 16. At this time, the drilling assembly 16 starts under the precise control of the PLC controller 12. The drilling motor inside drives the drill bit to rotate at high speed, while the feed mechanism drives the drill bit to move slowly in a direction perpendicular to the workpiece surface. During the drilling process, the three-jaw chuck 141 firmly clamps the workpiece, ensuring that the workpiece will not be displaced or shaken under the action of the high-speed rotating drill bit, thus ensuring the accuracy and perpendicularity of the drilling. After the drilling depth reaches the preset value, the feed mechanism of the drilling assembly 16 drives the drill bit to move in the opposite direction, completing the retraction of the drill bit, and the drilling process ends. After drilling is completed, the shift motor 142 drives the three-jaw chuck 141 to rotate, so that the drill hole opening faces downward, and the debris inside the hole is initially cleaned by gravity. Subsequently, the slide 14 continues to move the workpiece, and the synchronous frame 23 moves synchronously with the slide 14. Under the guidance of the first guide rail 24 and the second guide rail 25, the ball bearing 213 at the bottom of the bending frame 211 rolls along the first support 233, and the ball bearing 223 at the bottom of the push rod 222 slides along the second support 235. When the push rod 222 enters the first half of the insertion slope 251, the positioning shaft 22 drives the bristles 221 to gradually insert into the barrier sleeve 2. Due to the size design of the barrier sleeve 2, the bristles 221 will naturally bend inside the barrier sleeve 2. This bending state not only prevents the bristles 221 from spreading out excessively during the movement, but also accumulates elastic potential energy for the subsequent cleaning action. At this time, the two remain relatively close, and the barrier sleeve 2 provides initial guidance and limit for the bristles 221, ensuring alignment with the drilled hole position to be cleaned. After entering the latter half of the insertion slope 251, under the lifting action of the lifting slope 241, the bending frame 211 drives the blocking sleeve 2 to move upward. At the same time, the push rod 222 pushes the positioning shaft 22 and the brush bristles 221 to rise synchronously under the guidance of the insertion slope 251. Because the size of the blocking sleeve 2 is smaller than the drilling size, the two are smoothly inserted into the drilling hole together, and the presence of the blocking sleeve 2 will not push the debris to the top of the drilling hole. After the barrier sleeve 2 and brush bristles 221 are fully inserted into the borehole, as the slide block 14 continues to move, the bending frame 211 slides along the lower section of the lifting slope 241. Under the elastic force of the compression spring 234, it drives the barrier sleeve 2 to move downward, creating a relative positional change with the brush bristles 221. At this time, the friction wheel 3 on the side wall of the push rod 222 just contacts the friction plate 31 on the plane 252, generating friction during relative motion, which drives the positioning shaft 22 and the brush bristles 221 to rotate. The brush bristles 221, which were originally bent inside the barrier sleeve 2, unfold under the action of rotational centrifugal force and their own elasticity, tightly adhering to the inner wall of the borehole, directly cleaning the residual debris. The barrier sleeve 2, after moving downward, forms a certain space below the borehole, facilitating the falling of debris from the gap between the brush bristles 221 and the barrier sleeve 2, achieving thorough cleaning. After cleaning, as the slide block 14 moves, the push rod 222 slides down the inclined plane 253. Under the elastic force of the return spring 236, the positioning shaft 22 drives the brush bristles 221 to move down and separate from the drill hole; at the same time, the bending frame 211 drives the blocking sleeve 2 to reset under the action of the compression spring 234. The workpiece finally moves to below the tapping assembly 17, and the tapping assembly 17 is then activated. The tapping motor in the tapping assembly 17 drives the tap to rotate, and its feed speed matches the tap pitch to ensure that the tap can smoothly tap into the drill hole. During the tapping process, the tapping assembly 17 will precisely control the number of rotations and feed depth of the tap according to the preset thread specifications to process the required internal thread. After tapping is completed, the tapping motor rotates in the opposite direction, driving the tap to retract, and the tapping process ends. The debris generated during the entire processing slides down the inclined surface of the worktable 1 for easy collection and cleaning. Through the coordinated operation of various components, the integrated processing of industrial lifting door drive shafts, from drilling and debris removal to tapping, has been achieved, effectively improving processing efficiency and workpiece quality.
