Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of punching equipment, in particular to a punching equipment for manufacturing construction machinery. Background Art
[0002] In the field of construction machinery manufacturing, special-shaped curved steel plates (such as arched supports and curved connecting plates) are widely used due to their need to adapt to complex mechanical structures. However, drilling these workpieces has long faced two major technical bottlenecks: 1. Clamping adaptability defects: Conventional universal clamps such as flat-nose pliers and electromagnetic chucks can only clamp flat areas on the workpiece edge. For steel plates with variable curvature or non-standard arcs, a hanging section is easily formed between the clamping point and the processing area, resulting in severe cutting vibration during drilling, seriously affecting hole accuracy and wall thickness uniformity.
[0003] 2. Localized Lack of Rigidity: Due to the curved surface, the central area of the steel plate lacks effective support. This can easily cause plastic deformation of the plate under the axial pressure of the drill bit, increasing the scrap rate and potentially leading to safety hazards such as drill bit chipping.
[0004] Current improvement plans mostly use customized mold supports, but they have significant limitations: the mold manufacturing cost is high and the cycle is long, which cannot adapt to the needs of small-batch and multi-specification production; the contact area between the rigid support body and the workpiece curved surface is too large, and the support body surface is easily damaged during the drilling operation (especially when drilling through holes), causing equipment damage and processing interruption; the clamping mechanism lacks a pressure feedback mechanism, and excessive clamping will cause stress concentration and deformation of the curved plate.
[0005] Therefore, there is an urgent need to develop a special punching equipment with adaptive surface support, multi-point flexible clamping and anti-interference protection functions to solve the systematic technical problems in the processing of special-shaped arc steel plates. Summary of the Invention
[0006] In order to make up for the deficiencies in the prior art, the present invention provides a punching device for manufacturing construction machinery.
[0007] A punching device for manufacturing construction equipment, comprising a workbench, characterized in that: The workbench is equipped with a clamping support mechanism for clamping and supporting special-shaped arc-shaped steel plates. A manipulator is connected to one side of the workbench through a connecting arm. A drill bit is provided at the end of the manipulator. After the clamping support mechanism clamps the special-shaped arc-shaped steel plate, it supports the inner wall of the steel plate at multiple points, and then drilling can be performed at any position through the manipulator.
[0008] Furthermore, in order to better realize the present invention, the clamping support mechanism includes a base fixedly connected to the center of the workbench, and a number of round-head support columns are vertically connected above the base. The round-head support columns are a structure that can be telescoped up and down, and the top of the round-head support columns is telescoped up and down to rest against the inner wall of the special-shaped arc-shaped steel plate. A clamping mechanism is arranged around the base, and the clamping mechanism clamps the edge of the special-shaped arc-shaped steel plate.
[0009] Furthermore, in order to better implement the present invention, the top of the round-head support column is a spherical crown support end, and a pressure detection unit is provided inside the spherical crown support end.
[0010] Furthermore, in order to better realize the present invention, the clamping mechanism includes a first horizontal telescopic rod connected around the base, a limiting plate is fixedly connected above the end of the first horizontal telescopic rod, and a pressure detection unit is also provided on the limiting plate. The contraction of the first horizontal telescopic rod drives the limiting plate to clamp the special-shaped arc steel plate.
[0011] Furthermore, in order to better realize the present invention, several auxiliary support columns are also arranged around the base, and the auxiliary support columns include a second horizontal telescopic rod connected around the base, and a vertical telescopic rod is fixed to the end of the second horizontal telescopic rod. The structure of the vertical telescopic rod is the same as that of the round head support column. The auxiliary support column is used when the support point of the round head support column of the special-shaped arc steel plate is far from the clamping point of the limit plate, to fill the large gap and avoid deformation of the suspended part.
[0012] Furthermore, in order to better realize the present invention, an upward-facing camera is provided on the base, which collects images of the inner wall of the special-shaped arc-shaped steel plate, determines the position of the large gap through image recognition, and controls the corresponding auxiliary support column to support this place through the control chip.
[0013] The beneficial effects of the present invention are: 1. Adaptive curved surface clamping: Through the multi-point independent expansion and contraction and pressure feedback of the round head support column, it accurately adapts to the complex curvature of special-shaped curved steel plates, completely eliminates large-area overhangs, suppresses drilling vibration, and improves hole position accuracy.
[0014] 2. Rigid intelligent reinforcement: Auxiliary support columns dynamically fill support blind spots based on image recognition, and cooperate with the main support system to form a full-area rigid network, reducing the plastic deformation rate of the steel plate and eliminating the hidden dangers of drill bit chipping.
[0015] 3. Anti-overload protection: The limit plate and support column are equipped with built-in pressure detection units to adjust the clamping force and supporting force in real time to avoid permanent deformation of the workpiece caused by stress concentration and reduce the scrap rate.
[0016] 4. Cost and efficiency optimization: Abandoning customized molds, the universal support system is compatible with steel plates of different specifications, shortening equipment changeover time and adapting to small batch and multi-batch production needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0019] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0021] Figure 1-Figure 3 This is a specific embodiment of the present invention, which is a punching device for manufacturing construction machinery. The specific usage process of this embodiment is as follows: Initial clamping stage: The first horizontal telescopic rod 4031 of the clamping mechanism 403 is controlled to be fully extended, and the special-shaped arc-shaped steel plate 5 is placed on the base 401 , ensuring that the inner wall of the steel plate faces the round-head support column 402 .
[0022] The clamping process starts: the first horizontal telescopic rod 4031 retracts, driving the limit plate 4032 to clamp the edge of the steel plate. The pressure detection unit within the limit plate 4032 provides real-time pressure data to the control chip, which dynamically adjusts the stroke of the first horizontal telescopic rod 4031 to ensure uniform clamping force and prevent damage to the workpiece.
[0023] Adaptive support phase: The rounded support columns 402 extend and retract synchronously, their spherical caps adaptively contacting the inner curved surface of the steel plate. Each support column has a built-in pressure detection unit that feeds pressure data back to the control chip. This chip independently adjusts the extension and retraction of each support column to balance pressure at all support points, eliminating localized stress concentrations.
[0024] Intelligent reinforcement support: A camera on base 401 captures images of the steel plate's inner wall and uses an image recognition algorithm to analyze overhanging areas (such as sudden changes in curvature) not covered by round-headed support column 402. Based on this information, the control chip drives the second horizontal telescopic rod 4041 of auxiliary support column 404 to extend below the target area. The vertical telescopic rod 4042 extends and contacts the steel plate's inner wall. Its pressure detection unit simultaneously provides feedback to ensure that the reinforcement support pressure is consistent with that of the main support system.
[0025] Drilling operation stage: Robot 3 precisely positions the drill head to drill holes anywhere on the plate. The adaptive support system maintains plate rigidity throughout the process, suppressing cutting vibrations and ensuring hole accuracy and wall thickness uniformity.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
