[0002] In the field of modern machining, planar drilling and tapping is an extremely common and critical machining process, widely used in the manufacturing process of various parts, aiming to provide precise threaded holes and other structures for subsequent assembly, use and other stages.

[0003] Existing planar drilling and tapping devices are mostly equipped with a rotary platform. Their working principle involves securely placing the part to be machined on the rotary platform. As the platform rotates, different parts of the part are sequentially moved to the machining positions, thus gradually completing precision machining operations such as drilling and tapping. The use of a rotary platform, to a certain extent, integrates the machining process, improves the space utilization efficiency of the equipment, and enables multi-station machining to be carried out in an orderly manner.

[0004] In the prior art, there is a drilling and tapping integrated machine disclosed in patent application publication number CN 114102147 A.

[0005] However, such devices have the following problems in actual production applications: Currently, the common method for fixing and unloading parts on a rotary platform is to use clamps to position and secure the parts, ensuring that they do not shift or loosen during rotation and processing, thus guaranteeing machining accuracy. However, using clamps to fix parts affects the loading and unloading speed of parts on the rotary platform, which is detrimental to continuous and efficient processing. Summary of the Invention

[0006] In view of the problems pointed out in the background art, this utility model proposes a rotary tooling and automatic planar drilling and tapping device to solve the above-mentioned technical problems and improve the speed of loading and unloading parts.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A rotary tooling includes a rotatable rotary table, from which mounting platforms extend radially. Multiple mounting platforms are provided and spaced circumferentially around the rotary table. The upper side of each mounting platform has a first bearing platform and a second bearing platform, which are radially spaced around the rotary table. Positioning posts are provided on the upper sides of both the first and second bearing platforms. The left and right sides of the upper side of the first bearing platform are respectively provided with upwardly protruding clamping clips. Two second clamping clips are provided on the upper side of the mounting platform, located on the left and right sides of the second bearing platform.

[0009] The present invention is further configured such that the height of the first support platform is greater than the height of the second support platform.

[0012] The present invention is further configured such that the two holding clips are arranged in a figure-eight shape.

[0013] The present invention is further configured such that the second holding clamp is spaced apart from the first bearing platform, and a clamping groove is formed between the second holding clamp and the first bearing platform.

[0014] The present invention is further configured such that the mounting platform has six units.

[0015] An automatic planar drilling and tapping device includes a frame, on which the aforementioned rotating fixture is mounted.

[0016] The present invention is further configured such that the frame is equipped with a drilling device, a tapping device, and a robotic arm that can move up and down.

[0017] The present invention is further configured such that a pressing mechanism is provided on the lower side of the drilling device and the tapping device respectively.

Detailed Implementation

[0025] 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.

[0026] The present invention will be described below with reference to Figures 1-3:

[0027] Example: A rotary tooling includes a rotatable rotary table 1, which is circular.

[0028] Six mounting platforms 2 extend radially from the rotary table 1 and are equidistantly spaced around the rotary table 1. The arrangement of six mounting platforms 2 enables simultaneous processing of multiple parts, significantly improving processing efficiency and enabling batch processing. Each mounting platform 2 serves as an independent part-bearing and processing unit, possessing complete fixing and positioning functional components.

[0029] The upper side of the mounting platform 2 is provided with a bearing platform 3 and a bearing platform 4. The bearing platform 3 and the bearing platform 4 are arranged radially at intervals on the rotating platform 1, and the height of the bearing platform 3 is greater than the height of the bearing platform 4.

[0030] Positioning posts 5 are respectively provided on the upper side of the support platform 3 and the support platform 4. When the part is loaded, the positioning posts 5 can accurately extend into the corresponding holes pre-machined on the part, restricting the planar movement of the part from below. This not only ensures the initial position accuracy of the part on the mounting platform, but also prevents the part from shifting due to factors such as rotational centrifugal force and processing vibration during subsequent rotation and processing, ensuring that each processing step can be carried out accurately in the predetermined position.

[0031] The upper side of the support platform 3 is provided with upward protruding clamps 7 on both the left and right sides. The clamps 7 are arc-shaped and the two clamps 7 are located on the same circumference. The arc-shaped design is adapted to the cylindrical shape of the part and can closely fit the circumferential surface of the larger end of the part in the circumferential direction, providing a reliable lateral clamping force.

[0032] The mounting platform 2 has two clamping clips 2 8 on its upper side. The two clamping clips 2 8 are located on the left and right sides of the support platform 2 4. The clamping clips 2 8 are set higher than the support platform 2 4 and are arranged in a V-shape. The V-shape layout allows the clamping clips 2 8 to clamp one end of the part from both sides at an angle. Together with the clamping clip 1 7, it achieves all-round circumferential constraint on both ends of the part.

[0033] The rotary tooling using the above-mentioned technical solution greatly facilitates parts loading. In the initial loading stage, since the parts are not completely rigidly fixed, the operator only needs to manually place both ends of the part onto support platform 3 and support platform 4 respectively, utilizing the height difference between the support platforms and the positioning pin 5 to quickly achieve initial positioning. At this time, the part is in a relatively stable but easily adjustable state; even if the placement is slightly off, it can be easily fine-tuned and corrected. Next, clamping clamps 7 and 8 clamp the two ends of the part circumferentially, fixing them in place. The entire process requires no complex fixture installation or debugging, greatly shortening the loading time. Moreover, this loading method is not only suitable for manual operation but also equally compatible with automated loading by robotic arms. The robotic arm can quickly and accurately place the parts on the support platform and trigger the clamping clamps according to a preset program, providing strong support for the efficient operation of automated production lines.

[0034] When the part is loaded and drilling and tapping begin, it is clamped and fixed on its upper side. Combined with the previous fixing effects of the lower support platform, positioning pins, and circumferential clamps, a comprehensive three-dimensional fixing system is formed. From below, support platforms 3 and 4 support the weight of the part, while positioning pins 5 limit planar displacement. From the circumferential perspective, clamps 7 and 8 prevent rotation. From above, the additional clamping and fixing counteracts vertical vibrations and cutting forces during processing, ensuring the part remains perfectly still during machining, meeting the requirements of high-precision drilling and tapping. Even under high-speed rotation and heavy cutting conditions, the part can still stably maintain its predetermined machining position, ensuring the dimensional and positional accuracy of each threaded hole and drilled hole, effectively reducing the scrap rate and improving product quality.

[0035] After processing, the parts enter the unloading stage. Since the parts are not completely confined by traditional complex fixtures during loading and processing, they can be picked up manually or by a robotic arm. Compared to parts fixed by traditional fixtures, there is no need for cumbersome fixture disassembly steps, avoiding scratches, bumps, and other damage to the surface of the processed parts that may be caused by disassembling the fixtures. At the same time, the unloading time is greatly shortened, further compressing the entire processing cycle and speeding up the production line. This creates favorable conditions for enterprises to improve production efficiency and reduce production costs.

[0036] The second clamp 8 and the first support platform 3 are spaced apart, forming a clamping groove 83 between them. The spaced area provides necessary space for subsequent operations.

[0037] The gripping slot 83 is designed to accommodate robotic arms, a key piece of equipment in modern automated production. In the automated unloading process, the robotic arm needs to precisely and efficiently grasp finished parts, and the gripping slot 83 provides the ideal operating space for this. Its width and depth are precisely designed to allow the robotic arm's two fingers to enter smoothly without being too large, which would cause the part to wobble within the slot and affect gripping accuracy. After drilling and tapping are completed on the part, the gripping slot 83 becomes the channel for the robotic arm to approach the part, allowing the robotic arm to quickly position itself and grip the part from both sides, initiating a rapid unloading process.

[0038] An automatic planar drilling and tapping device includes a frame 9, on which the aforementioned rotating fixture is mounted. The frame 9 provides a stable mounting platform for all components of the device.

[0039] The frame 9 is equipped with a drilling device 10, a tapping device 11, and a robot arm 14 that can move up and down. The drilling device 10, the tapping device 11, and the robot arm 14 are arranged circumferentially on the rotating fixture.

[0040] The drilling device 10 has a drill rod that can move up and down and rotate independently. When drilling is started, the drill rod first adjusts its vertical position precisely according to the material of the part, the hole diameter requirements, and the preset machining parameters, using an independent drive system to quickly position it above the starting position of the hole to be drilled. Then, the drill rod rotates at high speed, powered by a specially equipped power unit, ensuring stable speed and appropriate torque to meet the cutting requirements of materials with different hardness. During rotation, the drill rod gradually moves downwards, using its sharp cutting edge to gradually remove material from the part, forming a precise circular hole.

[0041] Similarly, the tapping rod of the tapping device 11 has similar independent up-and-down movement and rotation functions. After the part is drilled, the tapping rod moves above the corresponding hole, first starts to rotate with precise speed and torque matching, and then slowly moves downward, using its thread structure to cut threads in the drilled hole, transforming the blank hole into a threaded hole that meets the assembly requirements.

[0042] The vertical movement capability of the robotic arm 14 allows it to interact with rotating fixtures at different heights. For example, after part processing is completed, it can pick up the part from the rotating fixture and send it to the next process, or place the part to be processed into a suitable position on the rotating fixture during loading. Simultaneously, the robotic arm 14 also has the ability to move towards each other to grip parts and to move away from each other to release parts. This flexible gripping method can efficiently and accurately complete part handling tasks, regardless of the size of the parts or the complex production line layout, greatly improving the flexibility and adaptability of automated production.

[0043] The drilling device 10 and the tapping device 11 are respectively equipped with a pressure mechanism on the lower side, which is a key line of defense to ensure that the parts remain stable during the processing.

[0044] The clamping mechanism includes a clamping rod 12, with a spring 13 sleeved at the lower end of the clamping rod 12. In its natural state, the lower end of the spring 13 is positioned below the lower end of the clamping rod 12. When the drilling device 10 or tapping device 11 moves downward according to the machining command, the spring 13, due to its own elasticity, makes initial contact with the surface of the part. Because the spring 13 has a certain degree of flexibility, it can buffer the impact force of the downward movement of the device with a relatively gentle force at the initial contact moment, avoiding hard damage to the surface of the part. At the same time, it can also adapt to the slight unevenness of the surface of the part, ensuring the initial clamping effect. As the device continues to move downward, after the spring 13 is compressed to a certain extent, the lower end of the clamping rod 12 also gradually clamps the part. At this time, the spring 13 is still in a compressed state, continuously providing upward elastic force, which, together with the rigid clamping force of the clamping rod 12, firmly fixes the part on the rotating fixture. During the machining process of the drill rod and tapping rod rotating and gradually moving down to process the parts, this double clamping mechanism can effectively resist interference factors such as cutting force and vibration during the machining process, ensuring that the parts remain motionless under the high-precision machining requirements, and ensuring that each drilling and tapping operation can be completed accurately, laying a solid foundation for producing high-quality products.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
