Description

Technical Field

[0001] The invention relates to the technical field of drilling machine tool structures, in particular to a multifunctional steering drilling machine tool for an aluminum alloy frame. Background Art

[0002] Aluminum alloy frames generally have various specifications of right-angled bent edge structures due to different installation purposes and requirements, forming a semi-enclosed shape with an opening. Therefore, most finished aluminum alloy frames have two layers of flat frames, upper and lower. In order to facilitate connection, holes need to be drilled on both layers of flat frames. The pain points in this type of drilling operation are: 1. The drilling positions on the upper and lower frames are not on the same plane and have different heights. Manual operation requires drilling one by one, and the range of manual movement is large, making it difficult to ensure the consistency of drilling requirements; 2. If the range of manual movement is reduced, it is necessary to design a relatively complex moving mechanism for the aluminum alloy frame workpiece, which is costly; 3. Since aluminum alloy frames are generally long strips, if both ends need to be drilled, two sets of drilling devices need to be arranged at the front and back ends of the machine tool, which is costly. If manual flipping is performed in the middle instead, multiple clamping and position change operations are required, which is inefficient; 4. The position of the drill hole during the drilling operation requires the assistance of additional tools such as a ruler, and it is difficult to ensure consistency during batch operations; 5. Since most aluminum alloy frames are the double-layer plane frame structure described above, the dust after drilling the upper layer is easy to stick to the edge of the hole or fall into the lower frame, resulting in dust residue inside the final aluminum alloy frame, which requires unified cleaning later, which is more troublesome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, a multifunctional steering drilling machine tool for an aluminum alloy frame is provided.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a multifunctional steering drilling machine for aluminum alloy frames, comprising a machine body, a top box arranged above the body, a fixture table arranged in the center of the body, a lifting table arranged on the right side of the fixture table, and a workpiece of the aluminum alloy frame to be drilled placed on the lifting table; A multifunctional elastic steering assembly is slidably connected to the left side of the front end of the fixture table through a slide rail A. An auxiliary side table with a slide rail B is provided on the right side of the lifting table. An insertable auxiliary block is slidably connected to the auxiliary side table. A drilling assembly is provided on the top box above the front end of the lifting platform; The multifunctional elastic steering assembly includes a column slidably connected to the slide rail A, a rotating sleeve connected to the column via a preloaded spring, a pressure plate connected to one end of the rotating sleeve, and a first guide through-hole group with a preset size and spacing formed on the pressure plate; when the workpiece is installed, the pressure plate is pressed against the upper support surface of the workpiece; the other end of the rotating sleeve is connected to the air nozzle via an elastic expansion and contraction device; The insertable auxiliary block includes a tightening head inserted into the workpiece, forming an inner concave cavity between the upper and lower end surfaces of the workpiece, and the tightening head presses the lower end surface of the workpiece against the lifting table surface, and the interior of the tightening head is a hollow structure; the auxiliary side platform is provided with an inner concave surface on one side of the tightening head, and the lower end of the inner concave surface is provided with a second guide through-hole group of preset spacing and size; A hoisting and steering clamping assembly is provided on the top box in the middle of the lifting platform. The hoisting and steering clamping assembly clamps the middle of the workpiece. The hoisting and steering clamping assembly includes two clamping jaws rotatably connected by a central connecting shaft and a torsion spring. The upper end of the central connecting shaft is rotatably connected to the hoisting terminal of the hoisting mechanism through a rotating shaft. When the workpiece is pressed down, the clamping claws are lowered into the corresponding clamping claw grooves on the left and right sides of the lifting table, and the workpiece is pressed against the lifting table at the same time; when the workpiece goes up and turns, the workpiece is lifted by the lifting mechanism and the workpiece can be manually turned forward and backward.

[0005] Furthermore, the drilling assembly described in the present invention includes a track column installed on the top box, a mounting plate is slidably connected to the track column, and drilling devices are installed on the left and right sides of the mounting plate through multi-slot connecting blocks, and the output ends of the drilling devices on the left and right sides respectively correspond to the first guide through hole group and the second guide through hole group.

[0006] Furthermore, the elastic expansion and contraction device of the present invention comprises a hollow tube connected to the rotating sleeve, a stretching rod is connected to the hollow tube via a spring, and the air nozzle is installed at the end of the stretching rod; By adopting the above technical solution, the operator can control the extension range by directly pulling out the air nozzle by holding it. After the blowing and cleaning is completed, the operator releases the nozzle, and the air nozzle retracts back to its original position under the action of the spring.

[0007] Furthermore, an air supply pump is installed on the top box of the present invention, and the air supply pump is connected to the air nozzle through an air pipe.

[0008] Furthermore, the lower end of the lifting platform of the present invention is provided with a hydraulic jacking device; By adopting the above technical solution, since the height of the workpiece sometimes varies slightly, setting the base as a lifting table with adjustable height is more conducive to fine-tuning during clamping, so that the workpiece can be clamped securely in all directions.

[0009] Furthermore, the fixture table of the present invention is provided with a torsion pressing block on one side of the slide rail A. When the workpiece is installed, the torsion pressing block rotates clockwise under the action of the torsion spring shaft inside it to press the workpiece; By adopting the above technical solution, the torsion clamping block realizes two functions: 1. When the bottom of the workpiece is placed with a longer side, the torsion clamping block rotates clockwise to the vertical direction to clamp and connect the side of the workpiece; 2. When the bottom of the workpiece is placed with a shorter side, under the action of the limiting column below, the torsion clamping block rotates clockwise to the horizontal direction and can also press and clamp the side of the workpiece in this state through the head end (the size of the torsion clamping block is preset according to the size of the commonly used workpieces).

[0010] Furthermore, a limiting column is provided on the fixture table of the present invention at the lower right side of the torsion pressing block, and the limiting column limits the torsion pressing block from rotating clockwise to a horizontal position.

[0011] Furthermore, the lower end of the lifting terminal of the present invention is provided with a connecting cavity, the upper end of the rotating shaft is provided with a convex edge, and the convex edge is rotationally limited in the connecting cavity; It can realize that the workpiece can be easily rotated and reversed when being hoisted.

[0012] Furthermore, in the present invention, a force-saving spring member is provided between the left and right clamping jaws; By adopting the above technical solution, since the two jaws tend to tighten inward under the pre-tightening force of the torsion spring, the force-saving spring component can prevent the two jaws from contacting and closing in the empty holding state before clamping, which can save effort for the operator when manually prying them open and clamping.

[0013] The beneficial effects of the present invention are: 1. The multifunctional steering drilling machine for aluminum alloy frames of the present invention improves the clamping of the aluminum alloy workpiece to be drilled in multiple directions and integrates detailed functions. This allows the workpiece to be mounted in place conveniently, quickly, stably and reliably, and can also achieve simultaneous drilling of double-layer frames. Furthermore, the machine is suitable for left-right and front-back steering of the workpiece, as well as drilling operations after steering. This significantly reduces the number of processes required by traditional methods, improves production efficiency, and enhances drilling consistency. 2. The multifunctional elastic steering assembly cleverly integrates the clamping function, drilling guide function, and air nozzle cleaning function, which can be easily achieved through spring and rotation operation; 3. The sliding auxiliary side table can not only press the head section of the workpiece, but also facilitate the simultaneous drilling of the bottom edge of the workpiece by setting a second guide through hole group that matches the drilling hole; 4. The hoisting and steering clamping assembly not only meets the needs of lifting and reversing the workpiece, but also can press the middle section of the workpiece against the lifting table through the cooperation of the clamping jaw groove when pressing down. Compared with the existing technology, it eliminates a lot of manual re-clamping and handling steps in the reversing operation; BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Working principle: 1. The aluminum alloy frame workpiece to be drilled is hoisted and pressed down. The middle part of the workpiece is clamped and connected to the clamping jaws of the hoisting and steering clamping assembly (the workpiece opening faces right, and the bottom is the longer side). The hoisting mechanism with a conventional lifting function is used to lower the clamping jaws until the workpiece is pressed against the lifting table. At this time, the left and right clamping jaws are placed in the corresponding clamping jaw slots, and the two clamping jaws also have a movable gap in the front and back of the clamping jaw slots to facilitate fine-tuning of the front and rear position of the workpiece (and, as needed, transverse rails can be arranged on the top box, and multiple hoisting and steering clamping assemblies can be arranged to achieve early hoisting and one-by-one processing of batch workpieces); 2. The torsion pressing block on the left side of the lifting table rotates clockwise under the action of its internal torsion spring shaft to press the side of the workpiece. The right end face of the workpiece is pressed against the left end face of the auxiliary side table (the upper and lower adaptation heights of the workpiece can be fine-tuned by the lifting function of the lifting table). The plug-in auxiliary block on the auxiliary side table is slid until the tightening head is inserted into the concave cavity of the workpiece. The tightening head presses the lower end face of the workpiece against the lifting table. Among them, such as Figure 4As shown, if the side of the workpiece needs to be drilled, the workpiece is clamped in the state that the opening of the workpiece faces upwards and the bottom is the shorter side. At this time, under the action of the limiting column below, when the torsion clamping block rotates clockwise to the horizontal direction, it can also press the side of the workpiece in this state through the head end (the size of the torsion clamping block can be preset according to the size of the commonly used workpieces); at this time, the pressure plate can also press the supporting end surface of the upper part of the workpiece and provide positioning guidance for the drilling operation in this state; 3. Manually lift the rotating sleeve and the pressing plate and rotate the pressing plate to one side of the workpiece so that the pressing plate is pressed against the upper support surface of the workpiece. Then, adjust the position on the slide rail A using the multifunctional elastic steering assembly so that the first guide hole group on the pressing plate is located at the preset position on the upper end surface of the workpiece. 4. According to the drilling requirements of the upper and lower sides of the workpiece, adjust the installation positions of the left and right drilling devices in the drilling assembly on the multi-slot connecting block, start the drilling devices, and press down the mounting plate so that the left and right drilling devices pass through the preset through-hole positions in the first guide through-hole group and the second guide through-hole group respectively, completing the simultaneous drilling work on the upper and lower sides of the workpiece; 5. After drilling is completed, rotate the rotating sleeve and hollow tube to rotate the elastic telescopic device to one side of the workpiece, pull out the air nozzle for blowing; 6. After the drilling operation is completed at the front end of the workpiece, after releasing the clamping operation at the front end of the workpiece, the operator can continue to lift the workpiece through the lifting mechanism. The operator can easily, safely, stably and quickly rotate the rear end of the workpiece to the front end and repeat the above operation.
