[0002] Thin-walled structural parts refer to lightweight structural parts composed of thin plates, thin shells and slender rods. Their wall thickness is usually thin and their appearance is usually complex, which requires precise design and processing technology to achieve. Thin-walled structural parts have the characteristics of light weight, good stress state, smooth geometric shape, etc. They can withstand large loads with less weight and less material. Therefore, they are widely used in aerospace, automobile, shipbuilding and other fields. Thin-walled structural parts play an important role in many fields. With the advancement of technology and the expansion of application fields, their application prospects will be broader.

[0003] When the existing thin-walled metal structural parts are subjected to chamfering machining on thin plates, it is not convenient to adjust according to the specifications of the thin plates, and only chamfering of thin plates of a single specification can be performed, which affects the benefits of the enterprise. Summary of the invention

[0004] The object of the present invention is to provide a device for chamfering thin-walled metal structural parts to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for mechanical chamfering of thin-walled metal structural parts, the device for mechanical chamfering of thin-walled metal structural parts comprises a table body, a base is installed on the table top of the table body, a storage block is installed on the base, two groups of first module guide rails are symmetrically installed on both sides of the storage block, a first slide seat is slidably installed on the two groups of the first module guide rails, a clamping plate is installed on the first slide seat, a second module guide rail is horizontally installed on the top of the table body, a second slide seat is slidably installed on the second module guide rail, an electric telescopic rod is installed on the second slide seat, and the electric telescopic rod is installed There is a first drive motor, on which a chamfering cutter head is installed. When the thin plate needs to be chamfered, the thin plate is placed on the storage block, and the first module guide rail is started, so that the first slide on both sides of the storage block can drive the clamping plate to move laterally, thereby being able to adjust the position of the clamping plate, which is convenient for clamping and fixing thin plates of different specifications. At the same time, the second module guide rail and the first drive motor are started, so that the first drive motor drives the chamfering cutter head to rotate, and the second slide drives the chamfering cutter head to move laterally through the electric telescopic rod, and then drives the chamfering cutter head to move longitudinally through the electric telescopic rod, so that it can be quickly adjusted according to the edges and corners of the thin plate.

[0006] Furthermore, a chamber is provided in the table body, a rotating hole is opened on the top of the chamber, a base is rotatably installed in the rotating hole, a second driving motor is installed at the bottom of the chamber, a transmission shaft is installed on the output shaft of the second driving motor, and the transmission shaft is connected to the bottom of the base. In an initial state, the center of the first driving motor, the placement block and the center of the base are on the same longitudinal central axis. When the thin plate is chamfered, the chamfering head moves to the processing position. At the same time, the second driving motor is started so that the second driving motor can drive the base to rotate through the transmission shaft, so that the base can drive the thin plate to rotate through the placement block, which is beneficial for the chamfering head to synchronously process and grind the four corners of the thin plate during the rotation process.

[0007] Furthermore, a rotating primary utilization component and a rotating secondary utilization component are arranged on the platform, and the operation of the second driving motor is utilized to provide operating driving force for the rotating primary utilization component and the rotating secondary utilization component.

[0008] Furthermore, the first-stage rotating utilization component includes a driving wheel, a first slideway, a first slider, a supporting spring, a connecting sleeve, a push-pull plate, a second slideway, a second slider, a traction plate and a positioning plate;

[0009] The transmission shaft is provided with a connecting sleeve, and the bottom of the connecting sleeve is connected to the first sliding block through a push-pull plate. The base is symmetrically provided with two sets of second sliding sleeves, and the second sliding block is slidably installed in the two sets of second sliding slides. The second sliding block is connected to the upper part of the connecting sleeve through a traction plate. A positioning plate is installed on the upper part of the second sliding block. The two sets of positioning plates and the two sets of clamping plates are cross-arranged. When the second driving motor is running, the high-speed rotation of the driving wheel disc is driven by the second driving motor, so that the first sliding block can compress the supporting spring under the centrifugal force to move horizontally in the first sliding block. During the horizontal movement, the first sliding block can drive the connecting sleeve to move downward along the driving shaft through the push-pull plate, and the connecting sleeve can drive the second sliding block to move horizontally in the second sliding block through the traction plate during the downward movement, so that the second sliding block can drive the positioning plate to position and fix the thin plate being processed, which can ensure the stability of the thin plate during chamfering.

When the driving wheel disc rotates, The driving wheel disc can drive the driven wheel disc to rotate through the transmission belt. At the same time, the driven wheel disc can drive the reciprocating screw to rotate synchronously through the rotating shaft during the rotation process, so that the moving seat can move back and forth longitudinally along the reciprocating screw. When the moving seat moves downward along the reciprocating screw, the moving seat can drive the sliding plug to move downward synchronously through the connecting rod, so that a suction effect is formed in the working cylinder, so that the working cylinder can adsorb the dust-containing gas formed in the chamfering process of the thin plate through the suction pipe and the dust collection pipe. When the moving seat moves upward along the reciprocating screw, the moving seat can drive the sliding plug to move upward through the connecting rod, so that an injection effect is formed in the working cylinder, which can enable the working cylinder to discharge the dust-containing gas into the gas purification device through the dust exhaust pipe, and realize the directional discharge of gas.
