DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example 1

[0022] In order to improve the drilling efficiency and drilling accuracy of steel components, an automatic positioning steel component drilling device is designed. The specific scheme is as follows:

[0023] like Figure 1-3 As shown, an automatic positioning steel component drilling device includes a machine platform 1 and a mechanical arm mechanism 2 arranged on the machine platform 1 and capable of realizing multi-axis movement, a clamping and positioning mechanism 4 and a drilling mechanism 3. The machine platform 1 is provided with a roller 102 type transmission mechanism, the mechanical arm mechanism 2 is a mechanical structure capable of realizing X-axis and Y-axis movement, the drilling mechanism 3 is installed on the mechanical arm mechanism 2, and laser projection and a camera are respectively provided on both sides of the drilling mechanism 3 to realize accurate positioning of the drilling position, the clamping and positioning mechanism 4 is arranged directly below the mechanical arm mechanism 2, and the clamping and positioning mechanism 4 includes a first clamping plate 401 that can be moved horizontally and a second clamping plate 403 that can be moved up and down, so as to adapt to the clamping and positioning of steel components of various shapes and structures.

[0024] The machine 1 is provided with a plurality of rollers 102 arranged along the front-rear direction of the machine 1. The plurality of rollers 102 are of a linkage structure. The rollers 102 are driven by a driving motor. The linkage structure of the rollers 102 can refer to the existing equipment structure and will not be described in detail.

[0025] The robotic arm mechanism 2 includes an X-axis arm 201 and a Y-axis arm 202. The lower end of the Y-axis arm 202 is fixedly mounted on the side of the machine platform 1. The X-axis arm 201 is slidably connected to the Y-axis arm 202. The drilling mechanism 3 is mounted on the X-axis arm 201. A turntable is provided between the drilling mechanism 3 and the X-axis arm 201 for rotating the drilling mechanism 3.

[0026] Specifically, the X-axis arm 201 and the Y-axis arm 202 both adopt a linear motor structure, and reference can be made to the existing linear motor robot arm. The X-axis direction is adjusted by the X-axis arm 201, and the Y-axis direction is adjusted by the Y-axis arm 202. When drilling from top to bottom, the X-axis arm 201 and the Y-axis arm 202 are used to adjust the horizontal adjustment and height adjustment of the drilling mechanism 3. During horizontal drilling operations, the drilling mechanism 3 is arranged horizontally, and the X-axis arm 201 can be used to control the advance and retreat of the drilling mechanism 3. Taking a square steel member as an example, the drilling mechanisms 3 on both sides can perform drilling operations at the same time, which improves the efficiency of the drilling operation and saves one-half of the original processing time. A fixed plate is also installed on the slider 502 of the X-axis arm 201 for installing a turntable. The turntable is a servo motor for adjusting the angle of the drilling mechanism 3.

[0027] The machine platform 1 is provided with two sets of mechanical arm mechanisms 2 symmetrically arranged on the left and right sides, and the two sets of mechanical arm mechanisms 2 are respectively a left arm and a right arm.

[0028] A connecting component 6 is provided at the front end of the left arm and the right arm to make the front end of the arms on both sides more stable to ensure the drilling accuracy. The connecting component 6 includes a telescopic cylinder, an insertion rod and a plug-in block. The telescopic cylinder is installed at the front end of the left arm or the right arm, the insertion rod is installed at the telescopic end of the telescopic cylinder, and the plug-in block is installed at the front end of the mechanical arm mechanism 2 opposite to the telescopic cylinder.

[0029] When the left and right arms are opposite to each other, the drilling mechanism 3 performs drilling operation at the front end of the arm. In order to reduce the vibration of the front end, the arms on both sides can be connected together through a connecting component 6 to improve stability. In this embodiment, a connecting component 6 is provided on the upper and lower parts of the left arm and the right arm. When connecting, the plug rod is inserted into the plug block through the telescopic cylinder to complete the connection.

[0030] The drilling mechanism 3 includes a mounting plate and a drilling head, a laser projection component, and a camera mounted on the mounting plate. A cooling pipe is fixedly mounted on the head, and the laser projection component and the camera are fixedly mounted on the lower end of the mounting plate.

[0031] Specifically, in this embodiment, the laser projection component can project a cross-shaped pattern on the steel component to mark the drilling position for the camera to collect images.

[0032] The clamping and positioning mechanism 4 includes a first clamping plate 401 component and a second clamping plate 403 component. The first clamping plate 401 component includes a first clamping drive 402 and a first clamping plate 401. The first clamping plate 401 is installed at the telescopic end of the first clamping drive 402. The second clamping plate 403 component is installed on the first clamping plate 401. The second clamping plate 403 component includes a second clamping plate 403 and a second clamping drive. The second clamping plate 403 is installed at the telescopic end of the second clamping drive. The second clamping drive is installed on the first clamping plate 401. Specifically, both sides of the first clamping plate 401 are L-shaped structures, which can be used to install the second clamping drive.

[0033] In this embodiment, the first clamping drive 402 and the second clamping drive both adopt a telescopic rod structure. In this embodiment, the telescopic rod structure is a hydraulic telescopic component. In the initial state, the first clamping plate 401 is located on both sides of the machine 1. When clamping and positioning is required, the first clamping drive 402 controls the clamping plate to clamp the steel member laterally, and then through the second clamping drive action, the second clamping plate 403 is lowered to clamp the top of the steel member. During the drilling operation, the clamping action is maintained. When the drilling position needs to be changed in the front and rear directions, the clamping is released, and the clamping and positioning is performed after the steel member moves. On the machine 1, it is not limited to one set of clamping drive components, and the steel member can be clamped more stably.

[0034] Installation boxes 101 are respectively provided on both sides of the machine platform 1 for installing and placing the main structure of the first clamping drive 402 .

[0035] The first clamping plate 401 is provided with an avoidance structure to avoid lateral interference and facilitate lateral drilling.

[0036] Specifically, in the present embodiment, the avoidance structure is a U-shaped avoidance opening, which is convenient for subsequent cleaning. In other schemes, the avoidance structure can be other shapes. When the drilling mechanism 3 performs transverse drilling, the avoidance structure will not be blocked, and the steel structure does not need to be clamped and positioned for the second time to complete the transverse drilling operation. On the descending path of the second clamping plate 403, the first clamping plate 401 is also provided with an avoidance opening to ensure that the second clamping plate 403 can be smoothly descended and clamped.

[0037] The two side edges of the machine platform 1 are also provided with a positioning assembly 5 that can be lifted and lowered, which can be used for front and rear positioning of the steel member. The positioning assembly 5 includes a positioning plate 501, a screw motor component and a lifting cylinder 504. The two ends of the positioning plate 501 are fixedly connected to the lifting cylinder 504, and the lifting cylinder 504 is slidably connected to the screw motor component.

[0038] Specifically, a slider 502 is provided on the screw motor, and a mounting base plate 503 is provided on the slider 502. The mounting base plate 503 is used to install a lifting cylinder 504. After the positioning plate 501 is raised, it can be moved back and forth through the screw motor component, so that the positioning plate 501 can be abutted against the front and rear ends of the steel component. It is mainly suitable for processing steel components with relatively short lengths. For steel components with longer lengths, the positioning plate 501 can be omitted.

[0039] Working principle:

[0040] Taking H-beam as an example, the H-beam moves on the conveying mechanism, and when the position where the hole needs to be drilled moves to directly below the drilling mechanism 3, it stops moving, and the first clamping plate 401 first clamps the H-beam, and then the second clamping plate 403 clamps the top of the H-beam.

[0041] After the H-shaped steel is clamped, the laser projection component will project a red cross mark on the H-shaped steel. The camera will collect the image of the marked part and compare the image with the preset image standard. If it meets the standard, the drilling mechanism 3 will start drilling downwards, and the cooling pipe will start spraying cooling water to ensure the normal use of the drill bit.

[0042] When horizontal drilling is required, the drilling mechanism 3 rotates 90 degrees and moves toward the Y-axis arm 202. The Y-axis arm 202 controls the X-axis arm 201 to move outward and at the same time lowers its height, so that the X-axis arm 201 is lowered to a suitable height. The X-axis arm 201 then controls the entire drilling mechanism 3 to move toward the H-shaped steel. After comparing and determining the drilling position, the drilling mechanism 3 starts horizontal drilling operations, which are repeated over and over again until the steel component is processed.

[0043] The automatic positioning steel component drilling device of the present scheme is provided with two symmetrical sets of mechanical arm mechanisms 2, each set of mechanical arms is provided with a drilling mechanism 3, which can drill two different positions on the steel component at the same time, and the drilling mechanism 3 can be controlled by the mechanical arm mechanism 2 to be located on the side of the steel component, which can be the same as drilling in the horizontal direction, and the drilling efficiency is higher. A clamping and positioning component 5 is provided on the machine table 1, which can clamp and position the steel component in multiple directions, and is suitable for steel components of various shapes, such as H-shaped steel, square steel, etc. The drilling mechanism 3 is provided with a laser projection component and a camera, which can realize accurate positioning of the drilling and ensure the processing accuracy. Example 2

[0044] In this embodiment, the device structure is basically the same as the device structure in Example 1, the difference is that the lower end of the Y-axis arm 202 is slidably connected to the machine platform 1, and the connecting part is a screw motor assembly, which can enable the entire robot arm mechanism 2 to move forward and backward, and the steel structure can be clamped once, and the drilling mechanism 3 can be moved to drill.

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
