Description

Technical Field

[0001] This invention relates to the field of drilling machine tool structure technology, and in particular to a multi-functional steerable drilling machine tool for aluminum alloy frames. Background Technology

[0002] Aluminum alloy frames generally have various specifications of right-angle bent edge structures due to different installation purposes and requirements, forming a semi-enclosed shape similar to an opening. Therefore, most finished aluminum alloy frames have two layers of flat frames, and due to the need for convenient connection, holes need to be drilled on both layers of flat frames.

[0003] The pain points of this type of drilling operation are as follows: 1. The drilling positions on the upper and lower frame layers are not on the same plane and are at different heights. Manual operation requires drilling one hole at a time, which involves a large range of manual movement and makes it difficult to ensure the consistency of drilling. 2. If the range of manual movement is reduced, a relatively complex moving mechanism needs to be designed for the aluminum alloy frame workpiece, which is costly. 3. Since the aluminum alloy frame is generally long and narrow, if drilling is required at both ends, two sets of drilling devices need to be arranged at the front and rear of the machine tool, which is costly. If manual flipping is used instead, multiple clamping and repositioning operations are required, which is inefficient. 4. The drilling position needs to be assisted by additional measuring tools, and it is difficult to ensure consistency in batch operations. 5. Since most aluminum alloy frames are double-layer planar frame structures as described above, dust from 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 aluminum alloy frame, which requires unified cleaning later, which is quite troublesome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-functional steering drilling machine tool for aluminum alloy frames in order to overcome the shortcomings of the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a multi-functional steering drilling machine tool for aluminum alloy frames, including a machine tool body, a top box provided on the top of the body, a fixture table provided in the center of the body, a lifting platform provided on the right side of the fixture table, and a workpiece of aluminum alloy frame to be drilled placed on the lifting platform.

[0006] A multi-functional elastic steering component is slidably connected to the front left side of the fixture platform via slide rail A. An auxiliary side platform with slide rail B is provided on the right side of the lifting platform. An insertable auxiliary block is slidably connected to the auxiliary side platform.

[0007] A drilling assembly is provided on the top box above the front end of the lifting platform.

[0008] The multi-functional elastic steering assembly includes a column slidably connected to the slide rail A, a rotating sleeve connected to the column via a pre-tightening spring, a pressure plate connected to one end of the rotating sleeve, and a first set of guide through holes of a preset size and spacing on the pressure plate; when the workpiece is installed, the pressure plate presses against the upper support surface of the workpiece; the other end of the rotating sleeve is connected to an air nozzle via an elastic telescopic device.

[0009] The insertable auxiliary block includes a clamping head inserted into the workpiece, forming a concave cavity between the upper and lower end faces of the workpiece. The clamping head presses the lower end face of the workpiece against the lifting platform. The inside of the clamping head is a hollow structure. A concave surface is provided on one side of the clamping head on the auxiliary side platform. A second guide through hole group with a preset spacing and size is provided at the lower end of the concave surface.

[0010] The top box is provided with a hoisting and steering clamping assembly located 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 jaws that are 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.

[0011] When the workpiece is pressed down, the grippers are lowered into the corresponding gripper slots on the left and right sides of the lifting platform, and the workpiece is pressed onto the lifting platform at the same time; when the workpiece moves up and turns, the workpiece is lifted up by the hoisting mechanism and the workpiece can be manually turned forward and backward.

[0012] Furthermore, the drilling assembly of the present invention includes a track column installed on the top box, a mounting plate slidably connected to the track column, and drilling devices installed on both 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 and cooperate with the first guide through hole group and the second guide through hole group.

[0013] Furthermore, the elastic telescopic device of the present invention includes a hollow tube connected to the rotating sleeve, a tension rod connected inside the hollow tube by a spring, and an air nozzle installed at the end of the tension rod.

[0014] By adopting the above technical solution, the operator can directly pull out the nozzle by holding it, which can control the extension range. After blowing air to clean, the nozzle is released and retracted back into place under the action of the spring.

[0015] 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.

[0016] Furthermore, the lower end of the lifting platform described in this invention is provided with a hydraulic lifting device;

[0017] By adopting the above technical solution, since the height of the workpiece may sometimes vary slightly, setting the base as a height-adjustable lifting platform is more conducive to fine-tuning during clamping, so that the workpiece can be securely clamped in all directions.

[0018] Furthermore, a torque clamping block is provided on one side of the slide rail A on the fixture table of the present invention. When the workpiece is installed, the torque clamping block rotates clockwise under the action of its internal torsion spring shaft to clamp the workpiece.

[0019] By adopting the above technical solution, the torque clamping block achieves two functions: 1. When the bottom of the workpiece is the longer side, the torque clamping block rotates clockwise to the vertical direction to clamp the side of the workpiece; 2. When the bottom of the workpiece is the shorter side, under the action of the lower limiting post, the torque clamping block rotates clockwise to the horizontal direction, and the head end can also abut against and clamp the side of the workpiece in this state (the size of the torque clamping block is preset according to the size of commonly processed workpieces).

[0020] Furthermore, a limiting post is provided on the fixture table of the present invention at the lower right of the torque clamping block, and the limiting post restricts the torque clamping block from rotating clockwise to a horizontal position.

[0021] Furthermore, the lower end of the hoisting terminal of the present invention is provided with a connecting cavity, and the upper end of the rotating shaft is provided with a protruding edge, the protruding edge being rotatably limited within the connecting cavity;

[0022] It enables the workpiece to be easily rotated and reversed when it is lifted.

[0023] Furthermore, in this invention, a force-saving spring is provided between the left and right grippers;

[0024] By adopting the above technical solution, since the two grippers tend to tighten inward under the preload of the torsion spring, the force-saving spring component can prevent the two grippers from contacting and closing in the unloaded state before clamping, which can save effort for the operator when manually opening and clamping.

[0025] The beneficial effects of this invention are:

[0026] 1. The present invention provides a multi-functional directional drilling machine tool for aluminum alloy frames. By improving the clamping of the aluminum alloy workpiece to be drilled in multiple directions and integrating detailed functions, the workpiece can be installed in place conveniently, quickly, stably and reliably. It can also drill holes in double-layer frames at the same time. Furthermore, it is suitable for drilling operations when the workpiece is turned left and right, forward and backward, and after turning. This greatly reduces the number of steps in traditional methods, improves production efficiency, and improves the consistency of drilling.

[0027] 2. The multi-functional spring steering assembly cleverly integrates clamping, drilling guidance, and air nozzle cleaning functions, which can be easily achieved through spring and rotation operation;

[0028] 3. The sliding auxiliary side platform can not only press the head section of the workpiece, but also facilitate simultaneous drilling of the bottom edge of the workpiece by setting a second guide through hole group that matches the drilling.

[0029] 4. The lifting and steering clamping assembly can not only meet the lifting and forward and backward rotation of the workpiece, but also press the middle section of the workpiece onto the lifting platform through the cooperation of the clamping jaw groove when pressing down. Compared with the existing technology, it saves a lot of manual re-clamping and handling steps in the reversing operation. Attached Figure Description

[0043] The insertable auxiliary block 9 includes a clamping head 16 inserted into the workpiece 5. A concave cavity is formed between the upper and lower end faces of the workpiece 5.

[0049] A torque clamping block 30 is provided on one side of the slide rail A6 on the fixture table 3. When the workpiece 5 is installed, the torque clamping block 30 rotates clockwise under the action of its internal torsion spring shaft to clamp the workpiece 5.

[0050] A limit post 31 is provided on the fixture table 3 at the lower right of the torque clamping block 30. The limit post 31 restricts the torque clamping block 30 from rotating clockwise to a horizontal position.

[0051] The lower end of the lifting terminal 22 is provided with a connecting cavity 32, and the upper end of the rotating shaft 21 is provided with a protruding edge 33, which is rotatably limited within the connecting cavity 32. A force-saving spring 34 is provided between the left and right grippers 20.

[0052] Working principle:

[0053] 1. The hoisting and pressing of the aluminum alloy frame workpiece to be drilled involves clamping the middle of the workpiece onto the jaws of the hoisting and steering clamping assembly (the workpiece opening faces right, with the bottom being the longer side). A conventional lifting mechanism is used to lower the jaws until the workpiece is pressed against the lifting platform. At this point, the left and right jaws are placed in their corresponding jaw slots, and there is also a clearance between the front and back of the two jaws within the jaw slots, which facilitates fine-tuning of the workpiece's front and back position (and, as needed, a transverse track can be arranged on the top box, and multiple hoisting and steering clamping assemblies can be arranged to enable the pre-hoisting and individual processing of batch workpieces).

[0054] 2. The torque clamping block on the left side of the lifting platform rotates clockwise under the action of its internal torsion spring shaft to clamp the side of the workpiece. The right end face of the workpiece abuts against the left end face of the auxiliary side platform (the upper and lower adaptation height of the workpiece can be finely adjusted by the lifting function of the lifting platform). The insertable auxiliary block on the auxiliary side platform is slid until the clamping head is inserted into the concave cavity of the workpiece. The clamping head presses the lower end face of the workpiece against the lifting platform.

[0055] Among them, such as Figure 4 As shown, if drilling is required on the side of the workpiece, the workpiece is clamped in the following state: the workpiece opening faces upwards and the bottom is the shorter side. At this time, under the action of the lower limiting post, when the torque clamping block rotates clockwise to the horizontal direction, the head end can also press against the side of the workpiece in this state (the size of the torque clamping block can be preset according to the size of commonly processed workpieces); at this time, the pressure plate can also press against the upper support end face of the workpiece and provide positioning and guidance for the drilling operation in this state.

[0056] 3. By manually lifting the rotating sleeve and the pressure plate and rotating the pressure plate to one side of the workpiece, the pressure plate is pressed against the upper support surface of the workpiece. The position is adjusted on the slide rail A by the multi-functional elastic steering component, so that the first guide through hole group on the pressure plate is located at the preset position on the upper surface of the workpiece.

[0057] 4. According to the drilling requirements of the upper and lower sides of the workpiece, adjust the installation position of the drilling devices on the left and right sides of the drilling assembly on the multi-slot connecting block, start the drilling device, and by pressing down the mounting plate, make the drilling devices on the left and right sides pass through the preset through hole positions in the first guide through hole group and the second guide through hole group respectively, and complete the simultaneous drilling work on the upper and lower sides of the workpiece.

[0058] 5. After drilling is completed, rotate the rotating sleeve and hollow tube to rotate the elastic telescopic device to one side of the workpiece, and pull out the air nozzle to blow it out;

[0059] 6. After drilling is completed at the front end of the workpiece, and the clamping operation at the front end of the workpiece is released, the workpiece is lifted by the hoisting mechanism. The operator can then easily, safely, stably, and quickly rotate the rear end of the workpiece to the front end. The above operation can be repeated.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
