Description

Technical Field

[0001] This utility model relates to the technical field of window frame profile processing equipment, specifically a window frame profile opening device. Background Technology

[0002] Window frame profiles are widely used in door and window manufacturing, curtain wall structures, and industrial lightweight frame structures. Their processing typically requires high-precision drilling to meet assembly requirements such as connector installation and drainage hole placement. Existing drilling processes mostly rely on manual positioning or simple fixing devices in conjunction with traditional drilling machines. This processing method has several problems: firstly, the clamping method is unstable, easily causing profile misalignment or damage; secondly, manual profile feeding is inefficient and cannot achieve continuous operation.

[0003] While some automated drilling devices incorporate conveying mechanisms, they often lack coordinated control with the clamping structure, leading to inconsistent pace or repetitive positioning during conveying and clamping. Furthermore, existing conveying structures often employ roller or chain-driven methods, resulting in uneven clamping and drive slippage when handling slender aluminum profiles, severely impacting processing accuracy and efficiency.

[0004] Therefore, there is an urgent need for an automated device with a reasonable structure, reliable clamping, precise conveying, and suitable for continuous drilling operations of window frame profiles, in order to improve the processing efficiency and product quality of drilling operations.

[0008] In a preferred embodiment, the present invention can be further configured such that: a tension spring is connected to the surface of the foot pedal, and the other end of the tension spring is fixed to the surface of the vertical rod.

[0009] Specifically, the foot pedal can be used to deflect the first and second links, which are then pulled by the lever and connecting lug.

[0014] Specifically, the eccentric rotation of the eccentric roller sleeve, driven by the motor, enables the eccentric oscillation of the creeping block, which, in turn, works with the clamping effect of the fixed clamping strip to achieve the creeping conveying motion of the window frame profile.

[0015] The beneficial effects achieved by this utility model are as follows:

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following is in conjunction with the appendix Figures 1-5 This invention describes a window frame profile opening device provided by some embodiments of the present invention.

[0030] As shown in the figure, this utility model provides a window frame profile drilling device, including a drill frame 100, a support platform 200, and a positioning mechanism 300. The drill frame 100 is an integral support structure, with a drill 110 fixedly installed on its top for drilling operations on the window frame profile. The support platform 200 is slidably mounted on the surface of the drill frame 100, and its height is adjusted by the engagement of a rack on the drill frame 100 with a key on the support platform 200, thereby adjusting the position of the drill 110 to adapt to processing requirements at different heights.

[0031] One end of the support platform 200 is connected to a fixed clamping bar 210 via an elastic element, and a vertical rod 220 is fixedly connected to its bottom surface. The vertical rod 220 extends vertically to support the positioning mechanism 300. The positioning mechanism 300 includes a movable clamping bar 310, a foot pedal 320, and a conveying assembly 330. The movable clamping bar 310 is slidably mounted on the top surface of the support platform 200. One side of the movable clamping bar 310 is rotatably connected to a first connecting rod 311, and the other end of the first connecting rod 311 is rotatably connected to a second connecting rod 312 and a connecting lug 313. The bottom end of the connecting lug 313 is movably connected to the foot pedal 320 via a pull rod 314. The foot pedal 320 is rotatably mounted on the vertical rod 220. When the foot pedal 320 is stepped on, the pull rod 314 pulls the connecting lug 313 downward, thereby causing the first connecting rod 311 and the second connecting rod 312 to deflect in conjunction, causing the movable clamping bar 310 to slide towards the fixed clamping bar 210, clamping the window frame profile located therein. A ball bearing structure is provided between the movable clamping bar 310 and the fixed clamping bar 210, which can reduce the frictional resistance between the window frame profile and the clamping bar during the clamping process and improve the smoothness of profile conveying.

[0032] A tension spring is connected to the surface of the foot pedal 320, and the other end of the spring is fixed to the surface of the vertical rod 220. After the foot pedal 320 is pressed to complete the clamping action, the tension spring automatically resets when the foot pedal is released, which drives the moving clamp bar 310 back to its original position, thereby realizing the clamping and releasing action.

[0033] The conveying assembly 330 is fixed to the foot pedal 320 and its structure includes a fixed base 331, a motor 332, an eccentric roller sleeve 333, and a creeping block 334. The motor 332 is mounted at the bottom of the fixed base 331, and its output shaft is connected to the eccentric roller sleeve 333. The creeping block 334 is rotatably fitted onto the outer surface of the eccentric roller sleeve 333. The outer side of the creeping block 334 has a rough conveying surface facing the fixed clamping bar 210 for contacting the surface of the window frame profile. Driven by the motor 332, the rotation of the eccentric roller sleeve 333 causes the creeping block 334 to oscillate eccentrically. Combined with the clamping action of the fixed clamping bar 210, the creeping conveying of the window frame profile is achieved.

[0034] During operation, the operator uses the foot pedal 320 to activate the clamping mechanism and secure the window frame profile. Then, the conveying component 330 intermittently advances the profile, moving it between positions on the drill rig 110 for continuous drilling. The entire operation eliminates the need for frequent clamping and repositioning, improving drilling efficiency and processing quality.

[0035] To accommodate different window frame sizes, the movable clamping strip 310 can be adjusted to its initial position on the surface of the support 200 via a structure with sliding grooves and positioning holes, thus enabling the clamping of window frame profiles of different widths. The creeping block 334 in the conveying assembly 330 can be replaced with materials of different surface friction coefficients, such as silicone layers, rubber granule layers, or toothed structures, to adapt to the conveying needs of aluminum alloy profiles, PVC profiles, and other materials with different surface characteristics.

[0036] In automation upgrade applications, the foot pedal 320 component can be replaced with an electric actuator, such as a linear motor or cylinder, to replace manual pedaling through buttons or programmed control. This allows the device to be integrated into the production line to achieve fully automated clamping, conveying, and drilling processes, further improving automation and processing efficiency.

[0037] The above describes the specific embodiments of this utility model. The claims are supported by the accompanying drawings and the structure of each component. The scalability and applicability of this utility model are illustrated through multiple embodiments to ensure that it has sufficient disclosure and implementation support, and meets the patent substantive examination standards.

[0038] Working principle and usage process of this utility model:

[0039] This device consists of a drill frame 100, a support platform 200, and a positioning mechanism 300. The support platform 200 can slide up and down along the surface of the drill frame 100 to adjust the opening height. The positioning mechanism 300 includes a movable clamping bar 310, a fixed clamping bar 210, a foot pedal 320, and a conveying assembly 330, which can perform clamping, releasing, and conveying operations on the window frame profile.

[0040] Clamping and positioning principle: The operator places the window frame profile on the surface of the support 200. One edge is positioned by the fixed clamping strip 210. By stepping on the foot pedal 320, the foot pedal 320 drives the pull rod 314 to pull the connecting lug 313, guiding the first connecting rod 311 and the second connecting rod 312 to deflect. This pushes the movable clamping strip 310 to slide closer to the fixed clamping strip 210, thus completing the clamping of the window frame profile. During the clamping process, the ball bearings between the fixed clamping strip 210 and the movable clamping strip 310 reduce friction, protect the profile surface, and improve clamping stability, thereby facilitating stable drilling.

[0041] The principle of peristaltic conveying: Under clamping conditions, after drilling is complete, the conveying assembly 330 is driven by the motor 332. The output end of the motor is connected to the eccentric roller sleeve 333, which drives the peristaltic block 334 mounted on it to oscillate eccentrically. The rough surface of the outer side of the peristaltic block 334 contacts the window frame profile, forming a frictional pushing force on the profile under clamping constraints, realizing the intermittent advancement of the profile under clamping conditions, i.e., "peristaltic conveying". This allows the window frame profile to be transversely conveyed to the next drilling position.

[0042] Automatic reset and cyclic operation: When the foot pedal 320 is released, the tension spring causes the foot pedal and the moving clamp 310 to automatically reset, releasing the profile.
