Description

Technical Field

[0001] The present invention relates to the technical field of forming processing, and particularly relates to a forming processing device for a metal bracket of a PU pulley. Background Art

[0002] The metal bracket of the PU pulley (as shown in Fig. 9 ) generally refers to a metal component that supports and fixes the pulley made of PU material (polyurethane), and is used in various mechanical equipment and systems; the structural design of this bracket aims to provide stable support and ensure good running performance of the pulley during use; the metal bracket mainly consists of two bases, a round rod connected between the two bases, and a support plate installed on the base in an isosceles trapezoid structure. Installation holes for fixing the pulley are provided on the support plate, and these three components are usually connected by welding.

[0003] However, the existing welding process of the metal bracket relies on manual adjustment or uses simple mechanical devices to perform positioning welding in sequence. Among them, manual operation is affected by human factors and operation skills, and errors are likely to occur. It depends on the skills and experience of the operator for positioning, and the operation process is complex and error-prone, resulting in unstable welding quality; secondly, by using simple mechanical devices to perform positioning welding in sequence, multiple docking operations are required to complete the assembly of the entire metal bracket, which affects the efficiency of the welding process of the metal bracket. Moreover, thermal stress and deformation will occur during the welding process, so a certain amount of deformation will occur during multiple disassembly and assembly of the metal bracket, affecting the docking of subsequent components. The accumulation of these factors will lead to the risk of unstable structure of the metal bracket. Summary of the Invention

A waist groove 2551 is opened at a position corresponding to the guide rod on the fixed plate 23, and the two guide rods on the same rectangular plate 2550 slide through the corresponding waist groove 2551 and are fixedly connected with the corresponding limiting plate 252. A push-pull rod 2552 is slidably installed in the middle part of the fixed plate 23, and a disc 2553 is installed after the upper end of the push-pull rod 2552 penetrates the fixed plate 23, and a connecting rod 2554 is hinged between the disc 2553 and the rectangular plate 2550, and the lower end surface of the push-pull rod 2552 slides through the round tube 2430.

[0041] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the pushing portion 27 includes a U-shaped groove, and two groups of limiting components are symmetrically opened on the supporting plate 12 front and back, each group of limiting components is composed of two U-shaped grooves symmetrically installed on the left and right, and a bottom plate 270 is slidably installed in the U-shaped groove, and the upper end surfaces of the bottom plates 270 are installed with L-shaped plates 271, and the lower end surfaces of the two bottom plates 270 in the same group are jointly installed with a connecting plate 272, and the connecting plate 272 is slidably connected to the supporting plate 12, and a push-pull member for driving the two connecting plates 272 to move toward each other is provided on the fixed plate 23.

[0042] like Figure 2 As shown, the push-pull member includes a turntable 273 , and the turntable 273 is installed after the round tube 2430 passes through the supporting plate 12 , and a second connecting rod 274 is correspondingly hinged between the lower end surface of the turntable 273 and the connecting plate 272 .

[0043] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the driving part 26 includes a sleeve 260, which is slidably mounted on the push-pull rod 2552, and the upper end of the sleeve 260 is fixedly connected to the fixed plate 23. A fixed tube 261 is coaxially installed on the lower end surface of the turntable 273. The lower end of the sleeve 260 slides through the fixed tube 261 and the circular tube 2430. A track groove 262 is provided on the inner wall of the fixed tube 261. A guide column 263 that slides with the track groove 262 is provided on the sleeve 260. A hydraulic cylinder 264 is installed on the lower end surface of the supporting plate 12 through a support. A connecting plate 265 is installed on the telescopic section of the hydraulic cylinder 264. The lower end of the push-pull rod 2552 slides through the sleeve 260 and is fixedly connected to the connecting plate 265.

[0044] During the specific operation, the bases of the two metal brackets are manually placed at the positions of the two corresponding pushing parts 27, and the round rods of the metal brackets are placed at the positions of the two corresponding clamping parts 24. Then, the mounting holes on the support plates of the metal brackets are docked with the cylinders 254, and the support plates of the metal brackets are moved into the support limit grooves 253. Then, the hydraulic cylinder 264 pulls the push-pull rod 2552 downward through the connecting plate 265, and the push-pull rod 2552 pulls the disc 2553 downward. The disc 2553 pushes the two rectangular plates 2550 away from each other through the No. 1 connecting rod 2554, and the rectangular plates 2550 drive the corresponding limit plates 252 to the corresponding blocking plates. The plate 250 moves to squeeze the support plate of the metal bracket into the corresponding limit groove 253 and fix it. As the push-pull rod 2552 continues to move downward, the limit plate 252 and the blocking plate 250 interfere with each other to limit the horizontal movement of the limit plate 252, and the push-pull rod 2552 drives the fixed plate 23, the support plate 21 and the guide column 22 to move downward. The downward movement of the fixed plate 23 drives the sleeve 260 to move downward, and the sleeve 260 drives the fixed tube 261 to rotate to drive the clamping part 24 to squeeze and fix the corresponding round rod of the metal bracket, and push the base of the corresponding metal bracket through the pushing part 27 to make it squeeze and dock with the round rod of the metal bracket.

[0045] like Figure 2 and Figure 5 As shown, the linkage member 242 includes a square groove, and a square groove is provided on the lower end surface of the supporting plate 12 at a position corresponding to the clamping assembly, a driving rod 2420 is rotatably installed in the square groove, and a No. 2 waist groove 2421 is provided at both ends of the driving rod 2420, and a No. 3 waist groove is provided on the supporting plate 12 at a position corresponding to the slide plate 240, and a column 2422 is installed on the lower end surface of the slide plate 240, which slides through the corresponding No. 3 waist groove and the corresponding No. 2 waist groove 2421.

[0046] like Figure 4 and Figure 8 As shown, the guide groove 2432 is a diamond-shaped structure, the four corners of the guide groove 2432 are arc segments, the middle part of the track groove 262 is an arc segment, and the upper and lower parts of the track groove 262 are vertical segments parallel to each other.

[0047] During specific operation, the downward movement of the sleeve 260 drives the guide column 263 to slide from the upper vertical section of the track groove 262 through the middle arc section to the lower vertical section, and at this time, it drives the fixed tube 261 to rotate, and the fixed tube 261 drives the turntable 273 to rotate, and the turntable 273 synchronously drives the driving disk 2431 to rotate through the round tube 2430, and the driving disk 2431 first pushes the two push-pull plates 2433 away from each other through the cooperation of the guide groove 2432 and the roller shaft 2434, and the push-pull plate 2433 pushes the corresponding slide plate 240 away from the driving disk 2431, and the slide plate 240 pushed by the push-pull plate 2433 pushes the corresponding slide plate 240 to move toward the round rod of the metal bracket through the driving rod 2420 to squeeze and fix the round rod of the metal bracket, and at the same time, the rotation of the turntable 273 pulls the corresponding two connecting rods through the No. 2 connecting rod 274 The plates 272 are close to each other, and the connecting plate 272 pushes the base of the metal bracket to fit tightly against the round rod of the metal bracket through the L-shaped plate 271. Then, as the fixing plate 23 moves downward, the sleeve 260 slides in the lower vertical section of the track groove 262 through the guide column 263, so that the base of the metal bracket and the round rod of the metal bracket are kept docked and fit. At the same time, the fixing plate 23 can move downward to drive the support plate of the fixed metal bracket to fit the base of the metal bracket. Then, the external welding robot arm welds the connection between the three components of the metal bracket, and the support frame 10 is equipped with an external No. 1 motor for driving the shaft column 11 to rotate. The operation of the external No. 1 motor drives the support plate 12 to rotate through the shaft column 11, thereby driving the three components of the metal bracket to rotate after docking, so as to ensure that the external welding robot arm completely welds the required welding position.

[0048] After welding is completed, the hydraulic cylinder 264 pulls the push-pull rod 2552 to move upward, and the push-pull rod 2552 drives the two rectangular plates 2550 to move closer to each other through the disc 2553 and the No. 1 connecting rod 2554, so that the limit plate 252 is away from the corresponding support plate of the metal bracket, and then the cylinder 254 is separated from the mounting hole on the support plate of the metal bracket. After that, the limit plate 252 moves into place and is limited by the No. 1 waist groove 2551 and cannot move again. At this time, as the push-pull rod 2552 moves upward, it will drive the fixed plate 23, the support plate 21 and the guide column 22 to move upward, and the fixed plate 23 will drive the sleeve 260 to move upward. The sleeve 260 cooperates with the guide column 263 and the guide groove 2432 to make the turntable 273, the round tube 2430 and the drive disk 2431 rotate in the opposite direction to release the limit on the base of the metal bracket and the round rod of the metal bracket. Then, the metal bracket is replaced, and the above operation is repeated to continue the welding process of the metal bracket.

They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0050] In addition, the terms "first", "second", "number one", "number two" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "number one", "number two" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
