Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "installation", "connection" should be broad sense understanding, for example, it can be fixed connection, also can be detachable connection, or integrally connected, it can be direct connection, also can be indirectly connected through intermediate medium, it can be two element internal communication, for ordinary skilled person in the art, the above-mentioned term can be understood as the specific meaning in the utility model according to specific circumstances.

[0032] Please refer to Figures 1-6 A kind of high-efficiency drilling device for hardware machining, including base 1, the upper end of base 1 is provided with vertical drilling drilling machine 2, and four square distribution pneumatic push rod 3 located at the front end of drilling machine 2, the upper end of four pneumatic push rod 3 is fixed with the frame 4 of square structure in common;

[0033] Frame 4 bottom end is attached to two mirror image clamping pieces 5, the first shaft 502 is installed in the opposite end of two clamping pieces 5;

[0034] The upper end of base 1 is also fixed with two second shafts 6, and the same side first shaft 502 and second shaft 6 are hingedly connected with a connecting plate 7;

[0035] The upper end of base 1 is also fixed with spring leaf 9 between first shaft 502 and second shaft 6 through rivet 10, and spring leaf 9 two sides are respectively elastically attached to the bottom of two different connecting plates 7.

[0036] In the embodiment, spring leaf 9 is composed of two parts, including horizontal end attached to base 1 in parallel, and inclined end located on both sides of horizontal end and extending along the upper side of horizontal end, the included angle between two inclined ends and horizontal end is the same.

[0037] It should be noted that such structure design makes spring leaf 9 be able to produce uniform elastic deformation when stressed, when connecting plate 7 drives clamping piece 5 to open and close under the drive of pneumatic push rod 3, the inclined end of spring leaf 9 will change the relative angle with horizontal end, and the force in vertical direction will be partially converted into horizontal direction elastic force to connecting plate 7, so as to provide stable support and rebound force for clamping piece 5, ensure that clamping piece 5 moves smoothly during opening and closing.

[0038] In the embodiment, the elastic deformation included angle of inclined end and horizontal end of spring leaf 9 is 30 ° to 60 °.

[0039] It should be noted that when the included angle is less than 30°, the spring piece 9 provides relatively small elastic force, which is easy to cause the clamping piece 5 to be unstable; and when the included angle is greater than 60°, the spring piece 9 is easy to produce excessive stress concentration in the deformation process, which may cause the spring piece 9 to fatigue and damage, shorten its service life, and also affect the flexibility of the opening and closing of the clamping piece 5. Therefore, the included angle range of 30° to 60° can balance the elastic force output and structural stability of the spring piece 9.

[0040] In this embodiment, the elastic deformation included angle of the spring piece 9 is 60°, and the two clamping pieces 5 are in the maximum opening and closing state, and the distance is greater than 10 cm.

[0041] It should be noted that the setting of the maximum opening and closing state is to meet the clamping needs of different specifications of hardware, when a larger size hardware needs to be clamped, the pneumatic push rod 3 pushes the frame 4 to rise, so that the elastic deformation included angle of the spring piece 9 reaches 60°, at this time the distance between the two clamping pieces 5 is greater than 10 cm, which can provide enough clamping space for large workpieces. At the same time, this maximum opening and closing state is also the limit that the spring piece 9 can reach under the premise of ensuring the structural integrity and elastic force performance of itself, which ensures that the device can operate stably under various working conditions.

[0042] In this embodiment, the upper end of the clamping piece 5 is provided with a T-shaped sliding block 503 on both sides, and the clamping piece 5 is slidably arranged at the bottom of the frame 4 through the sliding block 503.

[0043] It should be noted that the design of the T-shaped sliding block 503 can effectively prevent the clamping piece 5 from falling off the frame 4 during sliding, ensuring the reliability of the connection between the clamping piece 5 and the frame 4. At the same time, the sliding cooperation of the sliding block 503 and the bottom of the frame 4 makes the clamping piece 5 open and close smoothly under the drive of the pneumatic push rod 3, improves the response speed and operation accuracy of the device, and facilitates the rapid and accurate adjustment of the position of the clamping piece 5 to adapt to the clamping of different workpieces.

[0044] In this embodiment, the opposite ends of the two clamping pieces 5 are provided with stepped grooves 501 for placing workpieces.

[0045] It should be noted that the design of the stepped groove 501 can adapt to different shapes and sizes of hardware. For some workpieces with stepped structures or special-shaped structures, the stepped groove 501 can provide multiple positioning surfaces, so that the workpiece can be placed more stably during clamping, reducing the shaking of the workpiece during drilling. In addition, the stepped groove 501 can also play a certain pre-positioning role, which facilitates the operator to quickly and accurately place the workpiece to the appropriate position, improving the clamping efficiency.

[0046] It needs to be further explained that the stepped groove 501 set after placing the workpiece exerts a drilling force vertically downward on the workpiece, which makes the clamping piece 5 clamp tighter, so that it is not easy to loosen during drilling.

[0047] In this embodiment, two mirror-symmetrical telescopic clamping jaws 8 are also provided on the frame 4, and the telescopic direction of the telescopic clamping jaw 8 is perpendicular to the sliding direction of the clamping piece 5 at the bottom of the frame 4.

[0048] It needs to be explained that the design of the telescopic clamping jaw 8 provides auxiliary clamping force for the workpiece from another dimension. When the clamping piece 5 clamps the workpiece mainly, the telescopic clamping jaw 8 can be extended to exert additional pressure from the side or top of the workpiece, further enhancing the stability of the workpiece. This multi-directional clamping method can effectively resist various directional forces and vibrations generated during drilling, ensuring that the workpiece always maintains a stable position during drilling, improving drilling precision.

[0049] It needs to be further explained that the telescopic clamping is located above the clamping piece 5, and there is no motion interference between them.

[0050] In summary: The high-efficiency drilling device for hardware machining drives the frame 4 to rise and fall by the pneumatic push rod 3, drives the clamping piece 5 to open and close, and forms an elastic support structure with the spring sheet 9 and the connecting plate 7. When drilling is vibrating, the drilling machine 2 exerts a vertical downward drilling force, and the clamping force of the two clamping pieces 5 will undoubtedly be further increased under the drilling vibration, effectively avoiding the problem of loosening of traditional clamps due to vibration, greatly improving the stability of workpiece clamping in drilling operation, and further ensuring drilling precision and hardware machining quality.

[0051] The high-efficiency drilling device for hardware machining realizes quick opening and closing of the clamping piece 5 through the pneumatic push rod 3 and the frame 4, simplifies the workpiece clamping process, and improves the operation convenience; at the same time, the clamping piece 5 sliding design cooperates with the stepped groove 501, which can quickly position different specifications of workpieces; the telescopic clamping jaw 8 assists clamping from another direction, and multi-dimensionally ensures the stability of the workpiece. The overall design improves the drilling precision while significantly improving the production efficiency, meeting the needs of efficient batch production.

[0052] Working principle: the hardware machining high efficiency drilling device through pneumatic drive, elastic buffer and multidirectional clamping synergistic effect, realize high efficiency stable drilling operation. Clamping first to be workpiece first through elastic clamping jaw complete predetermined positioning, pneumatic push rod 3 downward force, frame 4 compression connecting plate 7 rotation, while clamping piece 5 along the frame 4 bottom slide rail in close clamping workpiece, while telescopic clamping jaw 8 from the side auxiliary pressure, through the ladder groove 501 carding effect and drilling machine 2 vertical downward pressure, form three-dimensional stable clamping system. Drilling, drill bit press and vibration impact through clamping piece 5, connecting plate 7 transmission to spring piece 9, it through dynamic deformation will vertical impact into horizontal elastic force, continuously offset vibration and maintain clamping force, while pneumatic push rod 3 further cooperate stable clamping force, avoid the precision decline caused by traditional fixture due to thread / push rod loosening, guarantee processing quality and efficiency, after processing is completed, two clamping piece 5 will rebound under the elastic action of spring piece 9, convenient to take out, use more convenient, simple structure and strong stability.

[0053] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
