Description

Technical Field

[0001] The invention relates to the technical field of welding piece leveling, in particular to an automatic fixed-point leveling device for welding deformation embedded parts. Background Art

[0002] In many fields such as construction, machinery manufacturing, and bridge construction, embedded parts play a vital role in connection and support. Embedded parts are usually composed of a plane plate and an embedded part fixed at the lower end of the plate. Since the welding process is a local heating process, when the embedded part is welded to the plane plate, the weld and its surrounding area will be rapidly heated, while the temperature of the surrounding material is relatively low. According to the principle of thermal expansion and contraction, the weld area will expand when heated and shrink when cooled. This uneven thermal change will cause deformation of the embedded parts, such as bending and twisting. This deformation will affect the subsequent installation accuracy and use function of the embedded parts.

[0003] At present, the industry widely uses hydraulic correction machines to level the deformed embedded parts to restore their proper shape accuracy and meet the subsequent installation and use requirements. However, the existing hydraulic correction technology has many disadvantages.

[0004] First, in the process of dealing with the deformation and protrusion of the embedded plate, it is necessary to find the highest point of the embedded part protrusion, and align the pressure center of the hydraulic cylinder of the hydraulic correction machine with the highest point of the embedded part protrusion to press down; the operator needs to use tools to find the protrusion of the plate deformation. There are usually multiple protrusions, and they need to be searched many times. This process not only takes a lot of time, but also is limited by the subjectivity of human judgment, which is very easy to miss or misjudge, and the overall correction efficiency is low; Secondly, every time a protrusion is found on the embedded part, the operator has to place a pad on the protruding position of the material deformation. Only after the preparation is complete can the hydraulic cylinder of the hydraulic correction machine be started to press down and level to achieve local precise correction. For embedded parts with more complex deformation and more protrusions, the operator needs to repeat this tedious process many times, which is very labor-intensive. As the working time increases, the probability of human error will also increase significantly. Third, from the perspective of the supporting structure, since the embedded part is composed of a flat plate and an embedded part fixed at the lower end of the plate, when the embedded part is corrected, the existing technology is to support the two ends of the flat plate of the embedded part through two brackets. This simple support method is inadequate when facing complex deformation. When the protrusion is far away from the center of the embedded part, the brackets at both ends cannot provide effective support force on both sides of the protrusion. In the process of the leveling hydraulic cylinder pressing down the protrusion for leveling, the embedded part plate is very likely to shake, displace, or even cause secondary damage due to excessive local force, which seriously affects the leveling effect and product quality.

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] See also Figures 1 to 8 The embodiment of the present application provides an automatic fixed-point leveling device for welding deformation embedded parts, including a base 1, a gantry 2, a leveling mechanism 3, a side support mechanism 4, an adjustment support mechanism 5, and a fixed-point mechanism 6. The gantry 2 is fixedly installed on the base 1; the leveling mechanism 3 includes a leveling hydraulic cylinder 31 and a pressure plate 32. The leveling hydraulic cylinder 31 is fixedly installed on the gantry 2, and a pressure plate 32 is installed at the output end of the leveling hydraulic cylinder 31.

[0020] Among them, the side support mechanism 4 is set to two, and the side support mechanism 4 includes a first linear drive mechanism and a side bracket 41. The side bracket 41 is slidably installed on the base 1. The side bracket 41 is used to support the deformable embedded part. The first linear drive mechanism drives the side bracket 41 to move linearly along the length direction of the base 1; the top of the side bracket 41 can be set to a round rod structure; The embedded parts to be leveled are placed on two side brackets 41, which support both ends of the embedded parts. The positions of the side brackets 41 can be adjusted by the first linear drive mechanism. The two side brackets 41 can move independently, that is, they can move in the same direction or in opposite directions, so as to adapt to embedded parts of different lengths and types. It is also convenient to move the deformed protrusions to be corrected of the embedded parts to the bottom of the pressure plate 32, so as to facilitate the pressure plate 32 to level them.

[0021] Among them, the adjustment support mechanism 5 includes a second linear drive mechanism, a middle bracket 51, a lifting hydraulic cylinder 52, and a movable support plate 53. The middle bracket 51 is slidably installed on the base 1. The second linear drive mechanism drives the middle bracket 51 to move linearly along the length direction of the base 1. The middle bracket 51 is located between the two side brackets 41. The lifting hydraulic cylinder 52 is fixedly installed on the middle bracket 51. The output end of the lifting hydraulic cylinder 52 is fixedly connected to the movable support plate 53. The movable support plate 53 is used to support the deformation embedded parts; the top of the movable support plate 53 can be set as a round rod structure; The movable support plate 53 specifically supports the position of the deformed embedded part close to the deformation area to be leveled. For example, the deformation area to be leveled is located far away from the center of the embedded part, which is close to one of the side brackets 41 and far away from the other side bracket 41. If the deformation position is leveled, the side bracket 41 far away from the deformation position cannot provide effective supporting force. During the leveling process, the embedded part plate body is very likely to shake, displace, or even cause secondary damage due to excessive local force, which seriously affects the leveling effect and product quality. Therefore, by setting an adjustable support mechanism 5, the support position can be flexibly adjusted, and the middle bracket 51 is driven by the second linear drive mechanism to move to a position close to the deformation area to be leveled. The movable support plate 53 is driven to rise by the lifting hydraulic cylinder 52, and the movable support plate 53 supports the bottom of the flat plate body of the embedded part.

[0022] Among them, the fixed-point mechanism 6 includes a third linear drive mechanism, a transverse frame 61, a distance sensor 62, a linear actuator 63, a longitudinal plate 64, a pressing piece 65, and an elastic piece 66. The third linear drive mechanism drives the transverse frame 61 to move linearly along the length direction of the base 1. The transverse frame 61 moves in the storage space formed between the pressure plate 32 and the side bracket 41. The distance sensor 62 and the linear actuator 63 are fixedly installed on the transverse frame 61. The distance sensor 62 is set to multiple and distributed along the width direction of the base 1. The longitudinal plate 64 is installed on the linear actuator 63. The output end is driven by the linear actuator 63 to move linearly along the width direction of the base 1. The lower pressing piece 65 is slidably connected with the longitudinal moving plate 64 and moves in the vertical direction. One end of the elastic piece 66 is connected to the longitudinal moving plate 64, and the other end is connected to the lower pressing piece 65. The upper end of the lower pressing piece 65 is used to contact and cooperate with the lower end of the pressure plate 32, and the lower end of the lower pressing piece 65 is used to contact and cooperate with the deformation protrusion at the upper end of the deformation embedded part; the top of the lower pressing piece 65 is higher than the top of the transverse moving frame 61. When the lower end of the lower pressing piece 65 contacts and cooperates with the deformation protrusion at the upper end of the deformation embedded part, the pressure plate 32 will not contact the transverse moving frame 61.

[0023] The distance sensor 62 is a laser distance sensor 62, or an ultrasonic distance sensor 62, an infrared distance sensor 62, or a millimeter wave radar sensor. The elastic member 66 is a compression spring. The pressing member 65 includes a columnar portion and a disc portion fixed to the top of the columnar portion. The elastic member 66 is sleeved on the columnar portion, and the upper end of the elastic member 66 is connected to the lower end of the disc portion. The distance sensor 62 determines the position of the highest point of the protrusion on the upper end surface of the embedded part by detecting the distance between it and the upper end surface of the embedded part placed on the side bracket 41. The linear actuator 63 is an electric slide that can drive the longitudinal plate 64 to accurately move the preset displacement.

[0024] The working steps of this embodiment are as follows: 1. Control and adjust the support mechanism 5 to work. According to the length of the embedded part, the first linear drive mechanism drives and adjusts the distance between the two side brackets 41. Then, the embedded part to be leveled is placed on the two side brackets 41. The side brackets 41 support both ends of the embedded part. 2. Control the fixed-point mechanism 6 to work. The third linear drive mechanism drives the transverse frame 61 to move linearly along the length direction of the base 1. The distance sensor 62 passes over the embedded part to detect the distance between it and the upper end face of the embedded part. Each distance sensor 62 is distributed at different positions in the width direction of the embedded part to detect the protrusions at different positions in the width direction of the embedded part. By arranging a plurality of distance sensors 62 in the width direction of the embedded part and driving each distance sensor 62 to move in the length direction of the embedded part by the third linear drive mechanism, the concave-convex information at different positions on the upper end face of the embedded part can be detected. By comparing the detection data of each distance sensor 62, the highest point position of the protrusion on the upper end face of the embedded part can be determined. 3. Manually determine whether the highest point of the protrusion is located directly below the pressing plate 32, that is, whether the vertical projection of the protrusion can be completely located in the vertical projection of the pressing plate 32; if the protrusion is not located directly below the pressing plate 32, the two first linear drive mechanisms work synchronously to drive the two side brackets 41 to move, so that the highest point of the protrusion moves to the position directly below the pressing plate 32; 4. Control and adjust the support mechanism 5 to work, drive the middle bracket 51 to move through the second linear drive mechanism, drive the movable support plate 53 to rise through the lifting hydraulic cylinder 52, and the movable support plate 53 supports the bottom of the plane plate body of the embedded part; specifically, if there is no embedded part below the deformation area to be leveled, the movable support plate 53 moves to the position directly below the deformation area to be leveled, and supports the deformation area to be leveled directly below; if there is an embedded part at the deformation area to be leveled, the movable support plate 53 moves to the position close to the deformation area to be leveled, and supports the vicinity of the deformation area to be leveled; if the deformation area to be leveled is far from the center of the embedded part, the distance between the movable support plate 53 and one of the side brackets 41 and the deformation area to be leveled is roughly the same as that of the side brackets 41, thereby improving the leveling effect; 5. The third linear drive mechanism drives the transverse frame 61 to move, and the linear actuator 63 drives the longitudinal plate 64 to move, so as to move the lower pressing member 65 to the highest point of the protrusion on the upper end surface of the embedded part; 6. The leveling hydraulic cylinder 31 drives the pressing plate 32 to descend, and the pressing plate 32 presses down the pressing member 65, the elastic member 66 is compressed, and the lower end of the pressing member 65 abuts against the protrusion of the embedded part. By controlling the extension length of the leveling hydraulic cylinder 31, the correction degree of the pressing member 65 to the protrusion of the embedded part is controlled; 7. After the first leveling is completed, the leveling hydraulic cylinder 31 drives the pressing plate 32 to rise. Under the elastic restoring force of the elastic member 66, the elastic member 66 drives the pressing member 65 to automatically rise and move away from the embedded parts. 8. Repeat steps 2 to 7 to level the multi-point deformation positions of the embedded parts.
