Description

Technical Field

[0001] This invention belongs to the field of seismic bracing processing technology, and specifically relates to a gear hobbing hole-making device for seismic bracing processing. Background Technology

[0002] Seismic bracing is an important component in electromechanical seismic bracing devices. It connects with vibration damping connectors and plays a role in seismic resistance and vibration damping.

[0003] Currently, Chinese invention patent CN109014949B discloses a gear hobbing device for seismic bracing, belonging to the field of seismic technology for building electromechanical engineering. It includes a calendering edge mechanism, a rib-pressing mechanism, and a gear hobbing mechanism. The calendering edge mechanism has two calendering edge components arranged side-by-side. The upper calendering block of the calendering edge component is coaxially mounted on the upper calendering edge roller, and the lower calendering block is coaxially mounted on the lower calendering edge roller. The rib-pressing mechanism has an upper rib block coaxially mounted on the upper rib-pressing roller, and a lower rib block coaxially mounted on the lower rib-pressing roller. The gear hobbing mechanism has a left gear hobbing component and a right gear hobbing component arranged symmetrically. The left hob of the left gear hobbing component is coaxially mounted on the left hob support shaft and secured by the upper and lower pressure rollers of the left hob. The right hob of the right gear hobbing component is coaxially mounted on the right hob support shaft and secured by the upper and lower pressure rollers of the right hob. This invention enables the rolling and pressing of seismic bracing, effectively improving the quality of gear hobbing of seismic bracing and increasing production efficiency.

[0004] Existing methods for drilling holes in seismic bracing systems typically involve punching machines and gear hobbing machines. However, during the drilling process, the gear hobbing machine's axial rotational motion, coupled with the smooth forward movement of the seismic bracing system on an assembly line, can lead to uneven stress on the bracing during drilling. This results in skewed holes and incompletely drilled holes, leading to poor hole quality and frequent rework, thus reducing efficiency. Furthermore, since different seismic bracing models require different hole sizes, existing gear hobbing machines generally require disassembling and replacing the gear hobbing disc to fit the required tooth diameter. This method necessitates manual assistance during replacement, and the sharp teeth on the gear hobbing disc can easily cause injury to workers, posing a significant safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a gear hobbing hole-making device for processing seismic bracing. Its advantages are that the gear hobbing disc vibrates up and down during the hobbing process to assist in punching holes and that it can quickly adjust gear hobbing discs of different tooth diameters to make holes.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a gear hobbing hole-making device for processing seismic bracing, comprising a protective shell, a rotating column rotatably connected inside the protective shell, a roller slidably sleeved on the surface of the rotating column, gear hobbing discs of different sizes sequentially opened on the surface of the roller, and second wheel discs fixedly sleeved at both ends of the surface of the rotating column, a gear hobbing mechanism and an adjustment mechanism respectively provided inside the protective shell, the rotating column and the roller being rotatably connected inside the protective shell through the gear hobbing mechanism, and the roller being slidably sleeved on the surface of the rotating column through the adjustment mechanism.

[0007] The above technical solution utilizes a first motor to drive a gear hobbing disc to rotate during the gear hobbing process of the seismic brace. Gravity-driven rolling balls roll downwards inside the cavity groove, generating a downward impact force on the gear hobbing disc, causing it to vibrate up and down. This continuous up-and-down vibration of the gear hobbing disc during the hobbing process impacts the holes formed by the gear hobbing, reducing hole misalignment and incomplete hole opening, thus improving the efficiency and quality of hole making in the seismic brace. By installing gear hobbing discs of different sizes on the surface of the roller, and then rotating the handle to engage the ring gear and the circular gear, the roller slides left and right on the surface of the rotating column after engaging with the rotating threaded rod. The gear hobbing disc of the required tooth diameter is moved to the center position, allowing for the creation of corresponding holes during subsequent gear hobbing operations. This eliminates the need for repeated replacement of the gear hobbing discs, improving practicality.

[0008] The invention is further configured such that: the gear hobbing mechanism includes a first motor fixedly connected to one side of the top of the protective shell; the adjusting mechanism includes a rotating handle rotatably connected to the other side of the top of the protective shell; a fixed sleeve is fixedly connected to the output end of the first motor and the bottom of the rotating handle; a sliding block is provided at the output end of the first motor and the bottom of the rotating handle, which is slidably fitted onto the surface of the fixed sleeve; a sliding sleeve is slidably connected inside the fixed sleeve; a first spring is fixedly connected to the top of the sliding sleeve and is fixedly connected to the fixed sleeve; a first bevel gear and a third bevel gear are fixedly connected to the bottom of the sliding sleeve; and the first motor and the rotating handle drive the first bevel gear and the third bevel gear to rotate inside the sliding block through the first spring and the sliding sleeve, respectively.

[0009] By adopting the above technical solution, when the rotating column vibrates up and down, the sliding sleeve can slide up and down back and forth inside the fixed sleeve with the rebound force of the first spring, so that the first motor can drive the rotating column to rotate during the vibration of the rotating column.

[0010] The invention is further configured such that: a second bevel gear meshing with a first bevel gear is fixedly connected to one end of the rotating column near the first motor; a first wheel is rotatably connected inside the second wheel; a cavity groove is opened inside the first wheel; a gravity ball is rotatably connected inside the first wheel; a second spring fixedly connected to a protective shell is provided at the top and bottom of both ends of the rotating column; and an arc-shaped push plate slidably connected to the rotating column is fixedly connected to one end of the second spring near the rotating column.

[0011] By adopting the above technical solution, the gear hobbing disc vibrates up and down continuously during the gear hobbing process, impacting the holes formed by the gear hobbing, reducing the phenomenon of hole skew and incomplete hole opening, and improving the efficiency and quality of hole making for seismic bracing.

[0012] The invention is further configured such that: a central shaft fixedly connected to the first wheel is rotatably connected inside the rotating column; a fourth bevel gear meshing with a third bevel gear is fixedly connected to one end of the central shaft near the rotating handle; a ring gear is fixedly sleeved on the surface of the first wheel; a circular gear meshing with the ring gear is rotatably connected inside the second wheel; a threaded rod threadedly connected to the roller is fixedly connected to one end of the circular gear near the roller; and a limiting groove slidably connected to the roller is provided on the surface of the rotating column.

[0013] By adopting the above technical solution, the gear hobbing disc of the required tooth diameter is moved and adjusted to the center position, so that the corresponding hole can be made when the gear hobbing disc is used again. This eliminates the need to repeatedly replace the gear hobbing disc, thus improving practicality.

[0014] The present invention is further configured such that: a fixed block is fixedly connected inside the sliding block, and the bottoms of the third bevel gear and the first bevel gear, as well as the ends of the fourth bevel gear and the second bevel gear that are far apart from each other, are all rotatably connected to a connecting rod that is rotatably connected to the fixed block.

[0015] By adopting the above technical solution, the fixed block is moved up and down by the connecting rod, so that the rotating column vibrates synchronously up and down during the vibration process, thereby improving the tightness of meshing and reducing vibration.

[0016] The present invention is further configured such that: the inside of the roller is rotatably connected to a sliding ball bearing that is slidably connected to the limiting groove.

[0017] By adopting the above technical solution, the frictional force of the roller sliding on the surface of the rotating column is reduced, and the sliding stability is improved.

[0018] The present invention is further configured such that: a positioning rod is fixedly connected inside the fixed sleeve and slidably connected to the sliding sleeve, and the first spring is sleeved on the surface of the positioning rod.

[0019] By adopting the above technical solution, the sliding of the sliding sleeve inside the fixed sleeve is limited, thereby improving the sliding stability.

[0020] The present invention is further configured such that: both sides of the top of the protective shell are open and fixedly installed with heat dissipation meshes that cooperate with the first motor.

[0021] The above technical solution facilitates ventilation and heat dissipation for the first motor, thereby improving its operational stability.

[0022] The present invention is further configured such that: a support frame is fixedly connected to the bottom of the protective shell, a second motor is installed on one side of the outside of the support frame, and a drive wheel that is rotatably connected to the support frame is fixedly connected to the output end of the second motor.

[0023] By adopting the above technical solution, the second motor is turned on to drive the drive wheel to rotate, thereby driving the anti-vibration bracket placed on the top of the drive wheel to move at a constant speed, which facilitates the gear hobbing and hole making of it.

[0024] The present invention is further configured such that: one end of the drive wheel passes through the inside of the support frame and is fixedly connected to a pulley, and a linkage belt is fixedly sleeved on the surface of the pulley.

[0025] By adopting the above technical solution, the second motor can synchronously drive all drive wheels to rotate using pulleys and linkage belts, thereby improving the stability of the seismic bracing movement.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The gear hobbing disc is driven by the first motor to rotate. During the gear hobbing process of the seismic support, the gravity rolling ball rolls downward inside the cavity groove, thereby generating a downward impact force on the gear hobbing disc. This causes the gear hobbing disc to vibrate up and down repeatedly. As a result, the gear hobbing disc vibrates up and down continuously during the gear hobbing process, impacting the holes formed by the gear hobbing. This reduces the phenomenon of hole skew and incomplete hole opening, and improves the efficiency and quality of hole making in the seismic support.

[0028] 2. By installing hobbing discs of different sizes on the surface of the roller, and then rotating the handle to drive the ring gear to mesh with the circular gear, the roller slides left and right on the surface of the rotating column after it meshes with the rotating threaded rod. The hobbing disc of the required tooth diameter is moved to the center position, so that the corresponding hole can be made when hobbing the tooth again. The hobbing disc needs to be replaced repeatedly to improve practicality. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Example 1:

[0039] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A gear hobbing hole-making device for seismic bracing processing includes a protective shell 1. A rotating column 6 is rotatably connected inside the protective shell 1. A roller 2 is slidably sleeved on the surface of the rotating column 6. Gear hobbing discs 3 of different sizes are sequentially opened on the surface of the roller 2. Second wheel discs 7 are fixedly sleeved at both ends of the surface of the rotating column 6. A gear hobbing mechanism 4 and an adjustment mechanism 5 are respectively arranged inside the protective shell 1. The rotating column 6 and the roller 2 are rotatably connected inside the protective shell 1 through the gear hobbing mechanism 4. The roller 2 is slidably sleeved on the surface of the rotating column 6 through the adjustment mechanism 5. During the gear hobbing process of seismic bracing, the gear hobbing discs 3 are rotated by a first motor 401. Gravity rolling balls 410 roll downward inside the cavity groove 409, thereby generating a downward impact force on the gear hobbing discs 3. The gear hobbing discs 3 are set to vibrate up and down repeatedly. Thus, the gear hobbing discs 3 continuously vibrate up and down during the gear hobbing process to impact the holes formed by the gear hobbing, reducing the phenomenon of hole skew and incomplete hole opening, and improving the efficiency of seismic bracing hole making.

[0040] refer to Figure 6 , Figure 7 The gear hobbing mechanism 4 includes a first motor 401 fixedly connected to one side of the top of the protective shell 1. The adjusting mechanism 5 includes a rotating handle 501 rotatably connected to the other side of the top of the protective shell 1. A fixed sleeve 402 is fixedly connected to the output end of the first motor 401 and the bottom of the rotating handle 501. A sliding block 405 is provided at the output end of the first motor 401 and the bottom of the rotating handle 501, which slides in contact with the surface of the fixed sleeve 402. A sliding sleeve 403 is slidably connected inside the fixed sleeve 402. A first spring 404 fixedly connected to the top of the sliding sleeve 403 is fixedly connected to the fixed sleeve 402. The bottom of the sliding sleeve 403 is fixedly connected to the first bevel gear 406 and the third bevel gear 502 respectively. The first motor 401 and the rotating handle 501 drive the first bevel gear 406 and the third bevel gear 502 to rotate inside the sliding block 405 through the first spring 404 and the sliding sleeve 403 respectively. When the rotating column 6 vibrates up and down, the sliding sleeve 403 can slide up and down with the rotating column 6 inside the fixed sleeve 402 through the rebound force of the first spring 404, so that the first motor 401 can drive the rotating column 6 to rotate during the vibration of the rotating column 6.

[0041] refer to Figure 4 , Figure 5 , Figure 6 , Figure 7The rotating column 6 is fixedly connected to a second bevel gear 407 that meshes with the first bevel gear 406 at one end near the first motor 401. The first wheel 408 is rotatably connected inside the second wheel 7. The first wheel 408 has a cavity groove 409 inside. A gravity ball 410 is rotatably connected inside the first wheel 408. The top and bottom of both ends of the rotating column 6 are provided with second springs 411 that are fixedly connected to the protective shell 1. The second spring 411 is fixedly connected to an arc-shaped push plate 412 that is slidably connected to the rotating column 6 at one end near the rotating column 6. This causes the gear hobbing disc 3 to vibrate up and down continuously during the gear hobbing process, impacting the holes formed by the gear hobbing, reducing the phenomenon of hole skew and incomplete hole opening, and improving the efficiency of hole making quality of the seismic support.

[0042] refer to Figure 6 , Figure 7 The sliding block 405 is internally fixedly connected to a fixed block 414. The bottom of the third bevel gear 502 and the first bevel gear 406, as well as the ends of the fourth bevel gear 503 and the second bevel gear 407 that are far apart from each other, are all rotatably connected to a connecting rod 413 that is rotatably connected to the fixed block 414. The connecting rod 413 drives the fixed block 414 to move up and down, so that the rotating column 6 vibrates synchronously up and down during the vibration process, thereby improving the tightness of meshing and reducing vibration.

[0043] refer to Figure 7 The fixed sleeve 402 is fixedly connected to the positioning rod 8 which is slidably connected to the sliding sleeve 403. The first spring 404 is sleeved on the surface of the positioning rod 8 to limit the sliding of the sliding sleeve 403 inside the fixed sleeve 402, thereby improving the sliding stability.

[0044] refer to Figure 1 , Figure 6 Both sides of the top of the protective shell 1 are opened and fixedly installed with heat dissipation mesh 9 for use with the first motor 401, so as to facilitate ventilation and heat dissipation of the first motor 401 and thus improve the working stability.

[0045] Brief description of the usage process: By turning on the first motor 401, the first spring 404 and the sliding sleeve 403 drive the first bevel gear 406 to rotate and mesh with the second bevel gear 407, thereby causing the rotating column 6 to rotate. Then, the second wheel 7 rotates under the drive of the rotating column 6, thereby causing the inner first wheel 408 to rotate. As the rotating column 6 drives the roller 2 to rotate, the gravity ball 410 is affected by gravity and rolls downward inside 109, thereby generating a downward vibration force in the rotating column 6, so that the gear hobbing disc 3 can move in tandem during the rolling process. The rotating column 6 moves downward to drill holes in the seismic brace. As it moves downward, the second spring 411 deforms, and the rebound force of the second spring 411 pushes the arc-shaped push plate 412, thereby resetting the rotating column 6. Finally, the gravity ball 410 rolls downward inside the cavity groove 409, causing the gear hobbing disk 3 to move downward. At the same time, the rebound force of the second spring 411 causes the gear hobbing disk 3 on the surface of the roller 2 to vibrate up and down during the hobbing process, impacting the holes formed by the hobbing and improving the quality of the holes in the seismic brace.

[0046] Example 2:

[0047] refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 A gear hobbing hole-making device for processing seismic bracing includes a protective shell 1. A rotating column 6 is rotatably connected inside the protective shell 1. A roller 2 is slidably sleeved on the surface of the rotating column 6. Gear hobbing discs 3 of different sizes are sequentially opened on the surface of the roller 2. Second wheel discs 7 are fixedly sleeved at both ends of the surface of the rotating column 6. A gear hobbing mechanism 4 and an adjusting mechanism 5 are respectively arranged inside the protective shell 1. The rotating column 6 and the roller 2 are rotatably connected inside the protective shell 1 through the gear hobbing mechanism 4. The roller 2 is slidably sleeved on the surface of the rotating column 6 through the adjusting mechanism 5. By installing gear hobbing discs 3 of different sizes on the surface of the roller 2, and then rotating the rotating handle 501 to drive the ring gear 505 to mesh with the circular gear 506, the roller 2 slides left and right on the surface of the rotating column 6 after being threaded with the rotating threaded rod 507. The gear hobbing disc 3 of the required tooth diameter is moved to the center position, so that the corresponding hole can be made when gear hobbing holes are made again. Therefore, the gear hobbing discs do not need to be replaced repeatedly, which improves practicality.

[0048] refer to Figure 3 , Figure 4 , Figure 6 , Figure 7The rotating column 6 has a central shaft 504 that is fixedly connected to the first wheel 408. The end of the central shaft 504 near the rotating handle 501 is fixedly connected to a fourth bevel gear 503 that meshes with the third bevel gear 502. The surface of the first wheel 408 is fixedly fitted with a ring gear 505. The interior of the second wheel 7 has a circular gear 506 that meshes with the ring gear 505. The end of the circular gear 506 near the roller 2 is fixedly connected to a threaded rod 507 that is threaded through the roller 2. The surface of the rotating column 6 has a limiting groove 508 that is slidably connected to the roller 2. By moving the gear hobbing disc 3 of the required tooth diameter to the center position, the corresponding hole can be made when hobbing the tooth again. This eliminates the need to repeatedly replace the gear hobbing disc, thus improving practicality.

[0049] refer to Figure 6 The inner rotating part of the roller 2 is connected to the sliding ball 10 that is slidably connected to the limiting groove 508, which reduces the friction of the roller 2 sliding on the surface of the rotating column 6 and improves the sliding stability.

[0050] refer to Figure 1 , Figure 2 The bottom of the protective shell 1 is fixedly connected to a support frame 11. A second motor 15 is installed on one side of the support frame 11. The output end of the second motor 15 is fixedly connected to a drive wheel 12 that is rotatably connected to the support frame 11. By turning on the second motor 15, the drive wheel 12 is driven to rotate, thereby driving the anti-vibration bracket placed on top of the drive wheel 12 to move at a constant speed, which is convenient for making gear holes on it.

[0051] refer to Figure 1 , Figure 2 One end of the drive wheel 12 passes through the inside of the support frame 11 and is fixedly connected to the pulley 13. The surface of the pulley 13 is fixedly sleeved with the linkage belt 14, so that the second motor 15 can use the pulley 13 and the linkage belt 14 to drive all the drive wheels 12 to rotate synchronously, thereby improving the stability of the seismic support movement.

[0052] Brief description of the usage process: By rotating the handle 501, the first spring 404 and the sliding sleeve 403 drive the third bevel gear 502 to rotate and mesh with the fourth bevel gear 503. This causes the fourth bevel gear 503 to drive the central shaft 504 to rotate inside the rotating column 6. Then, the rotating column 6 drives the first wheel 408 to rotate, causing the ring gear 505 on the surface of the first wheel 408 to mesh with the circular gear 506. This causes the circular gear 506 to drive the threaded rod 507 to rotate and engage with the inside of the roller 2. As a result, the roller 2, under the limit of the limiting groove 508, drives the gear hobbing disc 3 to slide left and right on the surface of the rotating column 6. Different sizes of gear hobbing discs 3 can be adjusted to the center position, so that the anti-vibration bracket can be made to the required size when the first motor 401 is turned on next time.

[0053] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
