Description

Technical Field

[0001] This utility model relates to the field of workpiece measurement technology, specifically a workpiece fixing and measuring device for stamping equipment. Background Technology

[0002] Stamping is one of the core processes in the field of metal forming. It uses dies to apply high pressure to sheet metal to achieve forming processes such as punching, bending, and stretching. In high-speed and high-precision stamping, it is necessary to measure the workpiece data and rely on mechanical fixtures to fix the workpiece.

[0003] A search of Chinese patent CN219444844U reveals a workpiece clamping and positioning fixture for measurement. The fixture includes a base with a rotating groove on its top surface. A rotating disk is rotatably connected to the inner wall of the rotating groove. A first support plate is fixedly connected to the top surface of the rotating disk. A rotating shaft is rotatably connected through the top of the first support plate. A threaded rod is fixedly connected to one end of the rotating shaft. A threaded sleeve is threaded onto the outer wall of the threaded rod. A pressure block is fixedly connected to one end of the threaded sleeve. In this invention, the workpiece is clamped between the pressure block and the rotating plate by rotating the threaded sleeve on the threaded rod. During workpiece measurement, the user can rotate the rotating shaft in conjunction with the rotating plate to fully display the workpiece, reducing obstruction and facilitating more comprehensive measurement. This makes the fixture more user-friendly.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. In the process of fixing the workpiece, the fixing device often needs to be adjusted accordingly for workpieces of different thicknesses. The adjustment is time-consuming and the adjustment accuracy is poor, which is not convenient for fixing work. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a workpiece fixing and measuring device for stamping equipment.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a workpiece fixing and measuring device for a stamping equipment, including a mounting plate, on which two placement platforms are fixedly mounted, and two measuring rulers are fixedly mounted. A workpiece plate is placed on both placement platforms. A clamping mechanism is provided on the mounting plate, and the clamping mechanism includes two hydraulic cylinders symmetrically arranged on the mounting plate. Each hydraulic cylinder has an adjustment component on its telescopic end.

[0008] The adjustment assembly includes a fixed shell fixedly installed on the telescopic end of the hydraulic cylinder, a circular shell fixedly installed on the fixed shell, a rotating block rotatably installed on the circular shell, a threaded shank fixedly installed on the rotating block, and a fixed frame threadedly installed on the threaded shank and slidably connected to the fixed shell. A scale assembly and a stabilizing assembly are provided between the fixed shell and the fixed frame.

[0009] Each of the placement platforms has two movable slots, and the inner wall of each movable slot is connected to a second spring. The end of the second spring is connected to a limiting block that is slidably connected to the movable slot.

[0010] Furthermore, the fixing frame is provided with a through hole that is compatible with the measuring ruler.

[0011] Furthermore, the scale assembly includes two marking rulers symmetrically fixedly mounted on the fixed housing.

[0012] Furthermore, the scale assembly also includes two arrows symmetrically fixedly mounted on the mounting bracket.

[0013] Furthermore, the stabilizing component includes two side shells symmetrically fixedly mounted on the fixed shell. Each side shell has a first spring connected to its inner wall. The end of the first spring is connected to a connecting frame that is slidably connected to the side shell. The end of the connecting frame is fixedly mounted with a pressure plate that abuts against the fixed frame.

[0014] Furthermore, the stabilizing component also includes a threaded rod fixedly mounted on the connecting frame, and a compression nut that abuts against the side shell is threaded onto the threaded rod.

[0015] Furthermore, each of the side shells has a circular hole at its bottom end that is adapted to the threaded rod.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] 1. In this utility model, the thickness of the workpiece plate is measured by observing the measuring ruler. The threaded handle is turned so that the threaded handle drives the fixing frame to move along the fixing shell by the thread action. When the fixing frame moves, it drives the arrow to move. According to the mark ruler pointed to by the arrow, the fixing frame is moved to the appropriate position. By turning the compression nut, the pressure plate compresses the fixing frame to fix it. This makes it easy to adjust the fixing device for workpiece plates of different thicknesses and improves the adjustment accuracy.

[0018] 2. In this utility model, by placing the workpiece plate between multiple limiting blocks, the multiple limiting blocks cooperate with each other to limit the workpiece plate, thereby preventing the workpiece plate from shifting during the stamping process. Attached Figure Description

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] like Figures 1 to 5 As shown, an embodiment of this utility model provides a workpiece fixing and measuring device for a stamping equipment, including a mounting plate 1, two placement platforms 2 fixedly mounted on the mounting plate 1, two measuring rulers 3 fixedly mounted on the mounting plate 1, a workpiece plate 4 placed on both placement platforms 2, and a clamping mechanism provided on the mounting plate 1. The clamping mechanism includes two hydraulic cylinders 5 symmetrically fixedly mounted on the mounting plate 1, and an adjustment component is provided on the telescopic end of each hydraulic cylinder 5.

[0028] The adjustment assembly includes a fixed housing 6 fixedly mounted on the telescopic end of the hydraulic cylinder 5. A circular housing 7 is fixedly mounted on the fixed housing 6. A rotating block 8 is rotatably mounted on the circular housing 7. A threaded shank 9 is fixedly mounted on the rotating block 8. A fixed bracket 10, which is slidably connected to the fixed housing 6, is threaded onto the threaded shank 9. A scale assembly and a stabilizing assembly are provided between the fixed housing 6 and the fixed bracket 10. The fixed bracket 10 has a through hole adapted to the measuring scale 3. The scale assembly includes two marking scales 11 symmetrically fixedly mounted on the fixed housing 6. The scale assembly also includes scales symmetrically fixedly mounted on the fixed bracket 10. The two arrows 12 indicate that the stabilizing component includes two side shells 13 symmetrically fixedly installed on the fixed shell 6. Each side shell 13 has a first spring 14 connected to its inner wall. The end of the first spring 14 is connected to a connecting frame 15 that is slidably connected to the side shell 13. The end of the connecting frame 15 is fixedly installed with a pressure plate 16 that abuts against the fixed frame 10. The stabilizing component also includes a threaded rod 17 fixedly installed on the connecting frame 15. A compression nut 18 that abuts against the side shell 13 is threaded on the threaded rod 17. Each side shell 13 has a round hole at its bottom that matches the threaded rod 17.

[0029] In this embodiment of the invention, the operator controls the conveying equipment to transport the workpiece plate 4 onto two placement platforms 2. The thickness of the workpiece plate 4 is measured using a measuring ruler 3. The threaded handle 9 is turned, causing it to move the fixing frame 10 along the fixing shell 6 using the threaded action. The threaded handle 9 can also drive the rotating block 8 to rotate along the inner side of the circular shell 7. As the fixing frame 10 moves, it moves the arrow 12. Based on the marker ruler 11 indicated by the arrow 12, the fixing frame 10 is moved to the appropriate position. Finally, the compression nut 18 is turned, causing it to move the screw using the threaded action. The threaded rod 17 moves, causing the threaded rod 17 to drive the pressure plate 16 to move through the connecting frame 15. The first spring 14 can use its own elasticity to provide stable support for the connecting frame 15, causing the pressure plate 16 to press and fix the fixing frame 10, thereby facilitating the adjustment of the fixing device for workpiece plates 4 of different thicknesses and improving the adjustment accuracy. By controlling the extension end of the hydraulic cylinder 5 to retract the fixing end, the extension end of the hydraulic cylinder 5 drives the fixing frame 10 through the fixing shell 6 to cooperate with the placement table 2 to fix the workpiece plate 4. The workpiece plate 4 is then stamped by the stamping equipment.

[0030] Figures 1 to 5 As shown, each placement platform 2 has two movable slots 19, and the inner wall of each movable slot 19 is connected to a second spring 20. The end of the second spring 20 is connected to a limiting block 21 that is slidably connected to the movable slot 19.

[0031] In this embodiment of the utility model, the worker places the workpiece plate 4 between multiple limiting blocks 21, so that the multiple limiting blocks 21 cooperate with each other to limit the workpiece plate 4, thereby preventing the workpiece plate 4 from shifting during the stamping process.

[0032] By pressing the limiting block 21 into the inner side of the movable groove 19, it is easy to move the workpiece plate 4 out. After releasing the limiting block 21, the second spring 20 can use its own elastic force to drive the limiting block 21 out of the inner side of the movable groove 19.

[0033] Working principle: The operator controls the conveying equipment to transport the workpiece plate 4 to the two placement platforms 2. The operator observes and measures the thickness of the workpiece plate 4 by measuring the ruler 3. The operator turns the threaded handle 9, which drives the fixing frame 10 to move along the fixing shell 6 by the thread action. When the fixing frame 10 moves, it drives the arrow 12 to move. According to the mark ruler 11 pointed to by the arrow 12, the fixing frame 10 is moved to the appropriate position. By turning the compression nut 18, the pressure plate 16 presses the fixing frame 10 to fix the fixing frame 10. By controlling the extension end of the hydraulic cylinder 5 to retract the fixing end, the extension end of the hydraulic cylinder 5 drives the fixing frame 10 through the fixing shell 6 to work with the placement platform 2 to fix the workpiece plate 4.

[0034] By placing the workpiece plate 4 between multiple limiting blocks 21, the multiple limiting blocks 21 cooperate with each other to limit the workpiece plate 4.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
