Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment manufacturing technology, specifically a shower head drilling mechanism. Background Technology

[0002] Shower heads are bathroom products, and the drilling mechanism for shower heads is specifically designed for bathroom equipment manufacturing. This field focuses on the research, development, production, and manufacturing technology of bathroom products. Therefore, the drilling mechanism must not only meet the basic drilling function, but also adapt to the special requirements of bathroom products.

[0003] In the prior art, a precision servo-driven CNC drilling device for bathroom shower head processing, with publication number "CN216065650U", belongs to the field of bathroom product processing technology. Its key technical features include a drilling device body, a worktable fixedly connected to the front side of the drilling device body, a drainage groove on the top of the worktable, a side plate fixedly connected to the top of the drilling device body, a duct movably connected to the rear side of the inner wall of the side plate, a blower fixedly connected to the left side of the duct through the side plate, and a collection mechanism fixedly connected to the bottom of the worktable. During normal drilling operations, the drilling device body drills on the worktable, and the generated debris is blocked by the side plate, preventing it from splashing to the outside of the device, thus protecting the user and avoiding injury from debris or the hassle of cleaning after operation. The generated debris falls onto the worktable, and the blower blows airflow through the duct.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Traditional technologies use a greater number of linear modules, resulting in a more complex overall structure. This not only increases the manufacturing cost of the equipment but may also increase the difficulty and cost of installation, commissioning, and maintenance due to the structural complexity.

[0006] Traditional drilling devices lack automatic cleaning mechanisms, requiring manual cleaning of chips periodically. This not only increases the workload and time cost for operators, but may also affect the continuity of processing and product quality due to untimely cleaning. Even if a cleaning mechanism is installed, a separate prime mover is required to drive it, which also increases the manufacturing cost of the mechanism. Utility Model Content

[0007] The purpose of this invention is to provide a shower head drilling mechanism to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A protective frame is fixedly installed on the work platform, and a cleaning mechanism for cleaning the surface of the work platform is fixedly installed on the protective frame.

[0011] Preferably, the cleaning mechanism includes four pulley sets symmetrically arranged on the protective frame. Several brush rods are fixedly installed on the belts of every two pulley sets.

[0012] Preferably, driven bevel gears are fixedly installed on the axles of the two sets of pulleys, a transmission rod is rotatably installed on the protective frame, and driving bevel gears are fixedly installed at both ends of the transmission rod. The two driving bevel gears respectively mesh with the driven bevel gears on the axles of the two sets of pulleys.

[0013] When one of the pulley sets rotates, it drives the other pulley set to rotate in the opposite direction via the driven bevel gear and transmission rod.

[0014] Preferably, the rotating rod passes through the working platform, and a driving pulley is fixedly installed on the rotating rod. A driven pulley is fixedly installed at one end of one of the driven bevel gears, and a transmission belt is sleeved between the driven pulley and the driving pulley.

[0016] Preferably, the working platform has through slots at both ends, and a detachable chip collection hopper is provided at the position below the through slots on the working platform.

[0017] Preferably, a handle is fixedly installed on the chip collection hopper.

[0018] Preferably, a cooling turbine is fixedly mounted on the shaft of the main spindle motor, and a turbine housing is provided on the main spindle motor.

[0019] Preferably, a protective cover for protecting the spindle motor is fixedly installed on the lifting platform.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Using only two linear modules (Z-axis linear module and X-axis linear module) combined with the rotation of a three-jaw chuck, it is possible to perform hole machining tasks at different positions and angles on the shower head. Compared to traditional three-axis machining, which requires movement in the X, Y, and Z axes, this reduces the number of linear modules used, simplifies the structure, and lowers the manufacturing cost of the mechanism.

[0022] 2. The cleaning mechanism, linked with the drive motor, automatically cleans chips from the surface of the work platform, preventing excessive chip accumulation from affecting the normal operation of the device. In traditional linear modules, chips easily enter the transmission components during operation, affecting accuracy and lifespan. This cleaning mechanism, by promptly removing chips, prevents them from entering critical components such as the X-axis linear module, protecting the transmission components, improving the reliability and stability of the device, and reducing malfunctions and maintenance costs caused by chip issues.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-8 This utility model provides a technical solution:

[0034] Example 1:

[0035] A shower head drilling mechanism includes a base 1, which is the basic support component of the entire shower head drilling mechanism. On the upper surface of the base 1, relevant components of the Z-axis linear module 2 and the X-axis linear module 6 are fixedly installed.

[0036] The Z-axis linear module 2 is vertically mounted on the base 1 and consists of key components such as a motor, lead screw, guide rail, and slider. The motor, as the power source, is precisely connected to one end of the lead screw via a coupling, ensuring that the motor's rotational motion is stably and accurately transmitted to the lead screw. The lead screw is mounted on one side of the guide rail, arranged parallel to it. The slider is fitted onto the guide rail and can slide linearly up and down along it; the slider is fixedly connected to a nut on the lead screw.

[0037] The lifting platform 3 is fixed to the slider of the Z-axis linear module 2. This connection method ensures that the lifting platform 3 can move precisely and synchronously with the slider in the Z-axis direction, providing stable vertical displacement for subsequent drilling operations.

[0038] The lifting platform 3 is a rectangular metal platform whose main function is to support the spindle motor 4. The lifting platform 3 is tightly connected to the slider of the Z-axis linear module 2 to ensure that there is no loosening or displacement during movement. On the lifting platform 3, the spindle motor 4 is horizontally fixed to the lifting platform 3 by bolts through the bolt holes at the four corners, so that the axis of the spindle motor 4 is aligned with the Z-axis direction.

[0039] The spindle motor 4 provides the power for the high-speed rotation of the drill bit. Its housing is securely bolted to the lifting platform 3, and the motor's output shaft extends vertically downwards. A drill chuck 5 is mounted on the output shaft of the spindle motor 4 using a high-precision tapered fit or threaded connection. This connection method ensures a very high degree of concentricity between the drill chuck 5 and the output shaft of the spindle motor 4, thereby ensuring the stability and accuracy of the drill bit during high-speed rotation.

[0040] The drill chuck 5 is mounted on the output shaft of the spindle motor 4 and has an internal elastic jaw structure. When the drill bit needs to be clamped, the operator rotates the adjusting nut on the outside of the drill chuck 5 to retract the jaws inward, thereby tightly gripping the shank of the drill bit. The drill chuck 5 can accommodate drill bits of different diameters, and by adjusting the opening of the jaws, a firm grip on the drill bit is achieved, ensuring that the drill bit will not loosen or slip during drilling.

[0041] The X-axis linear module 6 is fixed to the base 1 in an inverted mounting manner. Unlike traditional linear modules, its sliding table is not a moving part, but is firmly fixed to one side of the base 1 by multiple bolts. The body of the X-axis linear module 6 is connected to the base 1 via a guide rail, and can move horizontally in a linear motion along the guide rail under the drive of a motor.

[0042] The X-axis linear module 6 also consists of components such as a motor, lead screw, guide rail, and slider. The motor is connected to the lead screw via a coupling, and the nut on the lead screw is fixed to the linear module body. When the motor starts, it drives the lead screw to rotate, and the nut moves along the guide rail as the lead screw rotates, thereby pushing the linear module body to move laterally along the guide rail.

[0043] The work platform 7 is fixedly mounted on the body of the X-axis linear module 6, forming an integral unit with the linear module. The work platform 7 is the carrier for placing the shower head workpiece to be processed. At the center of the work platform 7, a three-jaw chuck 8 is installed for clamping and positioning the workpiece.

[0044] The three-jaw chuck 8 is mounted on the work platform 7 via bearings and can rotate on the work platform 7. The three-jaw chuck 8 has a self-centering function. When the operator places the shower head workpiece on the three-jaw chuck 8 and rotates the adjusting nut of the chuck with a wrench, the three jaws will move inward or outward simultaneously, automatically centering the workpiece and clamping it in the center position of the chuck.

[0045] A worm gear 9 is fixedly installed on the side wall of the three-jaw chuck 8. The worm gear 9 rotates synchronously with the three-jaw chuck 8, providing a power transmission interface for the rotation of the three-jaw chuck 8.

[0046] The drive motor 10 is fixed to one side of the working platform 7, and its output shaft is connected to a rotating rod 11 via a coupling. As the power source for the rotation of the three-jaw chuck 8, the drive motor 10 can provide stable speed and torque output.

[0047] The rotating rod 11 is mounted on the working platform 7 via bearings and is connected to the output shaft of the drive motor 10 via a coupling. A worm gear 12 is fixedly sleeved in the middle part, and the other end passes through the side wall of the working platform 7. The rotating rod 11 rotates under the drive of the drive motor 10, thereby driving the worm gear 12 to rotate together.

[0048] The worm 12 and worm wheel 9 mesh with each other, forming a worm wheel 9-worm 12 transmission mechanism. The worm 12 is mounted on the rotating rod 11 and rotates with the rotation of the rotating rod 11. The worm wheel 9 is fixed to the side wall of the three-jaw chuck 8 and meshes tightly with the worm 12. When the worm 12 rotates, the rotational motion of the worm 12 is converted into the rotation of the worm wheel 9 through the meshing transmission between the worm wheel 9 and the worm 12, which in turn drives the three-jaw chuck 8 to rotate around its central axis, thereby realizing the angle adjustment of the shower head workpiece in the Z-axis direction.

[0049] The protective frame 13 is fixed to the work platform 7 by bolts and surrounds the three-jaw chuck 8 and the workpiece to be processed.

[0050] Its main function is to prevent chips generated during the drilling process from flying out, protecting the safety of operators, and also preventing chips from polluting surrounding equipment and the working environment.

[0051] In traditional linear module operation, the linear module is fixed to the equipment, and the sliding table drives the movement of other components. During the drilling process of the shower head, the generated chips fall due to gravity and can easily fall into the transmission components of the linear module (such as lead screws, guide rails, and sliders). The entry of chips increases wear between transmission components, reduces the accuracy and service life of the linear module, and may even cause the linear module to malfunction.

[0052] To address this issue, this drilling mechanism inverts the X-axis linear module 6. In this configuration, when the motor of the X-axis linear module 6 starts, it drives the lead screw to rotate. Since the sliding table is fixed to the base 1, the linear module body moves laterally along the guide rail under the push of the nut, thereby moving the work platform 7 and the workpiece on it together. This method makes it difficult for chips to enter the interior of the X-axis linear module 6 under gravity, effectively protecting the transmission components of the linear module and improving the reliability and stability of the mechanism.

[0053] Traditional three-axis machining typically utilizes movements along the X, Y, and Z axes to achieve omnidirectional machining of a product. However, for the small batches of custom shower heads processed by our facility, the hole machining requirements are relatively simple and do not require movement along the Y axis.

[0054] In this drilling mechanism, the Z-axis linear module 2 is responsible for controlling the lifting and lowering movement of the drill bit. When drilling is required, the Z-axis linear module 2 drives the lifting platform 3, the spindle motor 4, and the drill chuck 5 to descend together, so that the drill bit contacts and drills into the workpiece; after drilling is completed, the Z-axis linear module 2 drives them to rise again, and the drill bit is withdrawn.

[0055] The X-axis linear module 6 enables the lateral movement of the workpiece. By controlling the movement of the X-axis linear module 6, the horizontal position of the workpiece can be adjusted, thereby changing the drilling position.

[0056] The rotation of the three-jaw chuck 8 enables the workpiece to be adjusted in the Z-axis direction. When drilling is required at different angles, the drive motor 10 starts, which drives the worm gear 12 to rotate via the rotating rod 11. The worm gear 12 meshes with the worm wheel 9, thereby driving the three-jaw chuck 8 to rotate at a certain angle, so that the workpiece is rotated to the required angle position.

[0057] By coordinating the three movements of drill bit lifting in the Z-axis direction, workpiece lateral movement in the X-axis direction, and rotation of the three-jaw chuck 8, the task of machining holes at different positions and angles on the shower head can be completed using only two sets of linear modules (Z-axis linear module 2 and X-axis linear module 6), reducing the number of linear modules used and lowering the manufacturing cost of the mechanism.

[0058] During processing, the operator first places the shower head workpiece to be processed on the three-jaw chuck 8, using the self-centering function of the three-jaw chuck 8 to clamp the workpiece, ensuring that the center of the workpiece coincides with the center of the three-jaw chuck 8. Then, the Z-axis linear module 2, X-axis linear module 6, drive motor 10, and spindle motor 4 are connected to the digital controller (not shown in the figure) via signal lines, ensuring that each component can accurately receive control commands from the digital controller. The digital controller has a pre-programmed drilling program, which controls the movement of each component.

[0059] To help operators better understand how to use this mechanism, this embodiment provides one toolpath machining method:

[0060] S1: Under the control of the digital controller, the Z-axis linear module 2 begins to descend, driving the spindle motor 4, drill chuck 5, and drill bit downwards together. Once the drill bit is aligned with the center of the workpiece (due to the self-centering function of the three-jaw chuck 8, the center of the workpiece is the center of the three-jaw chuck 8), the spindle motor 4 starts, driving the drill bit to rotate at high speed and begin drilling the center hole. After drilling is complete, the Z-axis linear module 2 rises according to the program instructions, lifting the drill bit away from the workpiece.

[0061] S2: The digital controller issues a command to control the movement of the X-axis linear module 6, causing the work platform 7 to offset the workpiece a certain distance in the X-axis direction. After the offset is completed, the Z-axis linear module 2 descends again. Once the drill bit reaches the new position, the spindle motor 4 restarts to continue drilling. After drilling is completed, the Z-axis linear module 2 rises again. Then, the drive motor 10 starts according to the program settings, driving the worm gear 12 to rotate via the rotating rod 11. The worm gear 12 meshes with the worm wheel 9, thereby driving the three-jaw chuck 8 to rotate at a certain angle. After the three-jaw chuck 8 rotates to its position, the Z-axis linear module 2 descends, and the drill bit drills at the new angle position. By repeating the above steps, the second revolution of hole machining can be completed.

[0062] S3: The X-axis linear module 6 continues to offset according to the distance set in the program, repeating the steps in S2 to complete the third round of hole machining. This process is repeated continuously until the drilling process on the entire shower head is completed.

[0063] Example 2:

[0064] Based on Embodiment 1, a large amount of chips generated during processing will accumulate on the work platform 7. This chip accumulation not only affects the cleanliness of the work platform 7 but may also interfere with the workpiece positioning accuracy during the drilling mechanism's operation, and may even enter critical components of the device, affecting its normal use and lifespan. To solve this problem, this embodiment specifically provides a cleaning mechanism 14 on the protective frame 13, dedicated to cleaning the surface of the work platform 7 to ensure the continuous and stable operation of the drilling mechanism.

[0065] The cleaning mechanism 14 mainly consists of four pulley sets 15 symmetrically arranged on the protective frame 13. These four pulley sets 15 are respectively installed on the four side walls of the protective frame 13, with precise and symmetrical positions to ensure the uniformity of the cleaning work. Each pulley set 15 consists of two or more pulleys connected by a belt to form a transmission system.

[0066] Several brush rods 16 are fixedly installed on the belt of every two pulley sets 15. The brush rods 16 are usually made of materials with a certain degree of elasticity and wear resistance, such as nylon or steel wire, to ensure that they can effectively clean up chips without damaging the surface of the work platform 7. These brush rods 16 are evenly distributed along the length of the belt and maintain an appropriate contact distance with the surface of the work platform 7 so that the surface area of ​​the work platform 7 can be fully covered when the pulley set 15 rotates.

[0067] In this embodiment, in order to achieve coordinated movement between the pulley sets 15, driven bevel gears 17 are fixedly installed on the axles of the two pulley sets 15.

[0068] A transmission rod 18 is rotatably mounted on the protective frame 13, and drive bevel gears 19 are respectively installed at both ends of the transmission rod 18. The drive bevel gears 19 are fixed to the transmission rod 18 by welding or key connection to ensure that the drive bevel gears 19 can rotate synchronously when the transmission rod 18 rotates.

[0069] These two driving bevel gears 19 mesh with driven bevel gears 17 on the axles of the two pulley sets 15, forming a bevel gear transmission system. Through this meshing connection, when one pulley set 15 rotates, the driven bevel gear 17 on its axle rotates accordingly, which in turn drives the meshing driving bevel gear 19 to rotate. The driving bevel gear 19 then drives the other driving bevel gear 19 to rotate via the transmission rod 18, ultimately causing the other pulley set 15 to rotate in the opposite direction. This design allows the two opposing pulley sets 15 to work together to clean chips from the surface of the work platform 7.

[0070] To enable the cleaning mechanism 14 to work in coordination with the drive motor 10 of the drilling mechanism, the transmission system has been further optimized. The rotating rod 11 passes through the working platform 7, and a drive pulley 20 is fixed on the rotating rod 11 by a key connection or set screw.

[0071] A driven pulley 21 is fixedly installed at one end of one of the driven bevel gears 17. A transmission belt 22 is fitted between the driven pulley 21 and the driving pulley 20. The transmission belt 22 is usually made of high-strength, wear-resistant rubber material to ensure that it will not slip or break during long-term transmission.

[0072] When the drive motor 10 rotates, driving the rotating rod 11 to rotate, it drives the three-jaw chuck 8 to rotate. Simultaneously, the drive pulley 20 on the rotating rod 11 rotates accordingly. The drive pulley 20 drives the driven pulley 21 to rotate via the transmission belt 22. The driven pulley 21 then drives the driven bevel gear 17, which is coaxial with it, to rotate. In this way, the power of the drive motor 10 can be transmitted to each pulley group 15 through the pulley transmission system and the bevel gear transmission system, realizing the automatic operation of the cleaning mechanism 14.

[0073] It should be noted that since the rotating rod 11 and the three-jaw chuck 8 are connected by a worm gear 9 and a worm 12, although the three-jaw chuck 8 rotates at a relatively slow speed, the rotating rod 11 can rotate at a relatively fast speed, thereby driving the brush rod 16 to complete the cleaning of the work platform 7 at a relatively high speed.

[0074] To facilitate the collection of cleaned chips, through slots 23 are provided at both ends of the work platform 7. A detachable chip collection hopper 24 is installed below the through slots 23 on the work platform 7. The chip collection hopper 24 can be connected to the bracket below the work platform 7 via slots or other means, ensuring a secure installation and easy disassembly. A handle 25 is fixedly installed on the chip collection hopper 24, allowing operators to easily pick up and put down the chip collection hopper 24 when chips need to be cleaned.

[0075] Example 3:

[0076] To ensure effective heat dissipation during prolonged high-speed operation of the spindle motor 4, a cooling turbine 26 is fixedly installed on the other end of the spindle motor 4's shaft. The cooling turbine 26 is tightly connected to the shaft via a key or welding. When the spindle motor 4's shaft rotates, the cooling turbine 26 rotates at high speed, driving the surrounding airflow and creating a forced air cooling effect, effectively reducing the temperature of the spindle motor 4.

[0077] A turbine housing 27 is also provided on the main spindle motor 4. The turbine housing 27 encloses the cooling turbine 26, protecting it from external interference and guiding airflow to enhance heat dissipation. The turbine housing 27 is typically made of metal, which has good thermal conductivity and mechanical strength.

[0078] To further protect the spindle motor 4, a protective cover 28 is fixedly installed on the lifting platform 3. The protective cover 28 is connected to the lifting platform 3 by bolts or welding, and encloses most of the components of the spindle motor 4 to prevent chips, dust and other impurities from entering the spindle motor 4. At the same time, it can also play a certain role in sound insulation and protection, and extend the service life of the spindle motor 4.

[0079] Working principle: During use, the drive motor 10 rotates, which in turn drives the rotating rod 11 to rotate, and through the worm gear 9 and worm 12, drives the three-jaw chuck 8 to rotate. Simultaneously, the drive pulley 20 on the rotating rod 11 rotates accordingly. The drive pulley 20 drives the driven pulley 21 to rotate via the transmission belt 22. The driven pulley 21 is coaxial with one of the driven bevel gears 17, thereby driving the driven bevel gear 17 to rotate.

[0080] The driven bevel gear 17 meshes with the drive bevel gear 19 at one end of the transmission rod 18, causing the transmission rod 18 to rotate. The drive bevel gear 19 at the other end of the transmission rod 18 then drives another driven bevel gear 17 to rotate. These two driven bevel gears 17 are respectively mounted on the axles of two sets of pulleys 15, thus causing these two sets of pulleys 15 to start rotating. Since the four pulley sets 15 are interconnected through a belt and bevel gear transmission system, all four pulley sets 15 will rotate in a predetermined direction.

[0081] As the pulley assembly 15 rotates, the brush rod 16 fixed on the belt also moves. The brush rod 16 moves along the surface of the work platform 7, thoroughly cleaning the work platform 7 and pushing the accumulated chips towards both ends of the work platform 7.

[0082] The working platform 7 has through slots 23 at both ends. The chips pushed to both ends by the brush rod 16 fall into the detachable chip collection hopper 24 below through the through slots 23. The operator can easily pick up and put down the chip collection hopper 24 using the handle 25 on the chip collection hopper 24 for easy chip cleaning.

[0083] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
