Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, specifically a tapping device with a quick-release head. Background Technology

[0002] Tapping is a common machining process used to create internal threads in pre-drilled holes. With the increasing level of industrial automation, tapping operations have gradually shifted from traditional manual labor to mechanized and automated processes. Currently, most tapping equipment on the market is motor-driven, connected to the tapping head via a connector to achieve efficient workpiece machining.

[0003] However, in actual production, different workpieces have different requirements for thread specifications, standards, and precision, often necessitating the replacement of different models and specifications of tapping heads to adapt to varying processing needs. Existing tapping equipment has significant shortcomings in tapping head replacement: on the one hand, the replacement of traditional tapping heads is complex and cumbersome, usually requiring the use of special tools for disassembly and installation, which is time-consuming and reduces production efficiency; on the other hand, to adapt to different tapping needs, companies often need to equip themselves with multiple complete sets of tapping equipment, rather than just replacing tapping heads, which greatly increases equipment investment costs and space requirements.

[0004] Therefore, there is an urgent need for a tapping device with quick assembly and disassembly capabilities, which can conveniently and quickly replace tapping heads of different specifications, meet diverse thread processing needs, reduce equipment investment costs, improve production efficiency, and adapt to the flexibility requirements of modern industrial production.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1) This application achieves rapid disassembly and assembly of the tapping head through an innovatively designed bidirectional locking mechanism. The equipment adopts a cross-shaped double locking system composed of a central slider, an external control block, a vertical locking rod, and a horizontal insertion block, which firmly connects the tapping head to the connector. At the same time, the lock can be quickly released by a simple toggle operation. The operator only needs to toggle the lever and push the external control block to release the vertical and horizontal locks simultaneously, easily completing the disassembly of the tapping head. During installation, simply align the tapping head with the connector slot and insert it. The locking is automatically completed by utilizing the elasticity of the fastening spring and the auxiliary positioning of the magnetic connection. The entire process requires no special tools, greatly simplifying the tapping head replacement process and improving production efficiency.

[0020] 2) This application, through the standardized design of the tapping head and the quick-release connection mechanism, enables enterprises to meet various thread processing needs with only one set of basic equipment and multiple tapping heads of different specifications, which significantly reduces equipment investment costs.

[0038] Please see Figure 1-6 This utility model provides a technical solution: a tapping device with a quick-release head, comprising:

[0039] Fixed base 1;

[0040] Robotic arm 2 is mounted on fixed base 1;

[0041] The drive motor 3 is installed at the end of the robotic arm 2 away from the fixed base 1;

[0042] Connector 4 is fixedly connected to the motor shaft of drive motor 3. Connector 4 has a connecting groove 41 at the bottom and an inner groove 42 inside. A middle slider 6 is movably provided in the middle of the inner groove 42. An external control block 7 is fixed to one end of the middle slider 6. A horizontal insert block 71 is fixedly connected to one side of the bottom of the external control block 7. A T-shaped groove 61 is vertically opened through the inner side of the middle slider 6. A vertical locking rod 8 is movably passed through the inner side of the T-shaped groove 61. An auxiliary ring 81 is fixedly connected to the outer side of the vertical locking rod 8. A fastening spring 62 is fixedly connected between the top of the auxiliary ring 81 and the inner wall of the T-shaped groove 61. The vertical locking rod 8 passes through the inner side of the fastening spring 62. A lever 82 is fixedly connected to the top of the vertical locking rod 8 on the side away from the external control block 7. A limit block 83 is fixedly connected to the bottom of the lever 82 on the outer side of the connector 4.

[0043] The tapping head 5 is connected to the connector head 4. A first locking hole 51 is opened in the top of the tapping head 5, and a second locking hole 52 is opened in one side of the tapping head 5.

[0044] Specifically, this application achieves rapid disassembly and assembly of the tapping head through an innovatively designed bidirectional locking mechanism. The equipment adopts a cross-shaped double locking system composed of a central slider 6, an external control block 7, a vertical locking rod 8, and a horizontal insert block 71, which securely connects the tapping head 5 to the connector 4. At the same time, the lock can be quickly released by a simple toggle operation. The operator only needs to toggle the lever 82 and push the external control block 7 to simultaneously release the vertical and horizontal locks, easily completing the disassembly of the tapping head 5. During installation, simply align the tapping head 5 with the connector slot 41 and insert it. The locking is automatically completed by utilizing the elasticity of the fastening spring 62 and the auxiliary positioning of the magnetic connection. The entire process requires no special tools, greatly simplifying the tapping head 5 replacement process and improving production efficiency.

[0045] Reference manual attached Figure 2-3The top outer surface of the tapping head 5 has four sets of anti-deviation grooves 53 arranged in a regular annular array, and the connecting groove 41 is adapted to the shape of the top of the tapping head 5. Specifically, the middle part of the tapping head 5 has a cylindrical structure. Through the design of the anti-deviation grooves 53, the positioning accuracy and stability between the tapping head 5 and the connecting head 4 are effectively improved. The four sets of anti-deviation grooves 53 are precisely adapted to the shape of the connecting groove 41, forming a slot-type positioning structure, ensuring that the tapping head 5 can only mate with the connecting head 4 in the correct direction during installation, preventing installation errors. At the same time, the annular array distribution design of the anti-deviation grooves 53 provides multi-point support and constraint between the tapping head 5 and the connecting head 4, effectively preventing the tapping head 5 from shifting and loosening due to cutting force and vibration during the tapping process, ensuring the coaxiality and thread quality of the machining. This anti-deviation structure design also allows tapping heads 5 of different specifications to be quickly replaced through a unified interface standard, ensuring that the same positioning accuracy is maintained after each replacement, meeting the consistency requirements of high-quality thread machining, and improving the reliability and working efficiency of the entire tapping system.

[0046] Reference manual attached Figure 4 The upper and lower ends of the T-slot 61 are both cylindrical. The vertical locking rod 8 is fitted into the upper end of the T-slot 61 with a clearance fit, and the bottom of the vertical locking rod 8 is adapted to connect into the first locking hole 51. Specifically, the inner diameter of the upper end of the T-slot 61 is smaller than the inner diameter of the lower end of the T-slot 61, and the outer diameter of the auxiliary ring 81 is adapted to the inner diameter of the lower end of the T-slot 61. This design makes the movement trajectory of the vertical locking rod 8 in the T-slot 61 more stable and controllable, reducing the risk of jamming. When the bottom of the vertical locking rod 8 is inserted into the first locking hole 51, precise axial positioning is formed, ensuring the alignment and stability of the tapping head 5 and the connector head 4 in the vertical direction.

[0047] Reference manual attached Figure 5-6 The horizontal insert 71, located away from the external control block 7, is horizontally adapted and connected to the second locking hole 52. The horizontal insert 71 is perpendicular to the vertical locking rod 8. Specifically, the horizontal insert 71 and the second locking hole 52 form a lateral locking mechanism, complementing the vertical locking, significantly improving the safety and stability of the entire quick-release system. The perpendicular arrangement of the horizontal insert 71 and the vertical locking rod 8 creates a vertically intersecting bidirectional locking structure. This design effectively constrains the tapping head 5 in both horizontal and vertical directions, eliminating the risk of loosening or displacement during tapping. Especially under high-speed, high-torque tapping conditions, the lateral locking mechanism effectively resists radial forces and vibrations generated during cutting, maintaining the stability of the tapping head 5. Simultaneously, the horizontally movable connection makes the operation of the horizontal insert 71 more convenient and intuitive. Operators only need to push the external control block 7 to control the extension and retraction of the horizontal insert 71, achieving quick locking or unlocking, further improving the efficiency and convenience of tapping head 5 replacement.

[0048] Reference manual attached Figure 4 A first strong magnet 43 is fixedly embedded in the upper inner wall of the inner groove 42, and the lever 82 is magnetically connected to the first strong magnet 43 through vertical movement. Specifically, when the operator moves the lever 82 to disassemble the tapping head 5 and releases it, the lever 82 will automatically return to its original position under the magnetic force of the first strong magnet 43. In addition, when the lever 82 is magnetically connected to the first strong magnet 43, the connection stability of the vertical locking lever 8 is effectively improved. At the same time, the magnetic connection has a certain buffering capacity, which can absorb the impact and vibration during operation, reduce mechanical wear, and extend the service life of the components.

[0049] Reference manual attached Figure 4 A second strong magnet 44 is fixedly embedded in the inner wall of the inner groove 42 near the external control block 7. The external control block 7 magnetically engages with the second strong magnet 44 through horizontal movement. Specifically, this allows the horizontally placed insert 71 to automatically maintain its locked position under magnetic force. The operator only needs to gently push the external control block 7 to the magnetic attraction position to complete the locking, without the need for continuous force or precise positioning. (See attached instruction manual) Figure 6 During the disassembly of the tapping head 5, the height of the limiting block 83 is greater than the height of the leftmost side of the inner groove 42. The limiting block 83 has a limiting effect on the middle slider 6, the external control block 7, the horizontal insert block 71, and the lever 82.

[0050] The intermediate slider 6, external control block 7, horizontal insert block 71, and lever 82 all move within the connecting groove 41, and the widths of the intermediate slider 6, external control block 7, horizontal insert block 71, and lever 82 are all adapted to the width of the connecting groove 41. Specifically, all moving parts are located within the connecting groove 41, and their widths are adapted to the width of the connecting groove 41. This design firstly achieves efficient space utilization, making the entire quick-release mechanism compact and small in size, facilitating operation in limited spaces. Secondly, the precise dimensional fit ensures the accuracy and consistency of the movement trajectory of each component, avoiding problems such as jamming, offset, or loosening. Thirdly, since all moving parts are located within the connecting groove 41, a good protective effect is formed, reducing the impact of external environmental factors such as dust and chips on the movement of the mechanism, and improving the adaptability and reliability of the equipment under harsh working conditions. Furthermore, this compact and coordinated structural design reduces the risk of interference between components, reduces mechanical wear, and extends the service life of the equipment. At the same time, it ensures ease of operation and consistency, enabling different operators to easily master the replacement skills of tapping head 5, improving the standardization and efficiency of the production process, and meeting the comprehensive requirements of modern industry for equipment compactness, reliability, and ease of use.

[0051] When it is necessary to disassemble and replace tapping head 5, refer to the instruction manual attached. Figure 5The operator can push the vertical locking lever 8 upwards using the lever 82, causing the bottom of the vertical locking lever 8 to disengage from the first locking hole 51. At this time, the fastening spring 62 is compressed, and the first strong magnet 43 separates from the lever 82. (Refer to the attached instruction manual.) Figure 6 Next, the operator can push the lever 82 horizontally and pull the external control block 7 to disengage the horizontal insert 71 from the second locking hole 52. At this time, the second strong magnet 44 separates from the external control block 7, and the tapping head 5 can then be pulled out from the connecting groove 41 for replacement or disassembly. When the tapping head 5 needs to be installed, first insert the tapping head 5 into the connecting groove 41, then push the external control block 7 inward so that the horizontal insert 71 is inserted into the second locking hole 52. At this time, the vertical locking rod 8 corresponds vertically to the first locking hole 51. Under the elastic force of the fastening spring 62, the auxiliary ring 81 and the vertical locking rod 8 are synchronously reset, so that the vertical locking rod 8 is inserted downward into the first locking hole 51. At this time, the second strong magnet 44 is connected to the external control block 7, and the first strong magnet 43 is connected to the lever 82, thereby achieving the locking of the tapping head 5.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
