Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts, in particular to an automatic fixed positioning stamping device. Background Art

[0002] A car is made up of multiple components, many of which, including spring trays, spring bases and other parts, are mostly made by stamping;

[0003] According to the Chinese patent announcement number: CN216937987U, an automatic positioning device for stamping parts is disclosed. After the first stamping, the positioning guide post extends out of the outside of the positioning guide post to make the sleeve and the positioning guide post engage with each other. At the same time, the positioning guide post and the punching head are driven downward by the cylinder to perform a second stamping, so that the stamping part can be completely fitted with the mold to ensure that the quality of the stamping part can meet the standard. At the same time, the positioning guide post is not only a positioning element, but also a stamping element, combining the secondary stamping with the positioning, which ensures that the second stamping can be performed while saving costs. In this technical solution, the positioning guide post and the sleeve are initially arranged During installation, displacement may occur, resulting in a collision between the punch head and the positioning guide pin during the punching process, thereby causing the punch head's punching position to shift and affecting the accuracy of the punching shape. However, in the prior art, if a cylinder is used to drive the positioning guide pin to move upward to calibrate the sleeve position in advance, personnel may not be able to control the start and stop of the cylinder in a timely manner, and the force of the cylinder to drive the positioning guide pin to move upward is large. If there is a deviation in the position of the positioning guide pin and the calibration sleeve, a collision may occur between the positioning guide pin and the calibration sleeve, causing deformation, thereby affecting the subsequent normal fixing and positioning accuracy. For this reason, we propose an automatic fixing and positioning punching device. Utility Model Content

[0004] The utility model aims to provide an automatic positioning punching device to solve the problems in the background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an automatic fixed positioning punching device, comprising a punching rod and a static die assembly, wherein an upper end cover is fixedly installed at the bottom end of the punching rod, the static die assembly is arranged below the lower end cover, a base is fixedly installed at the bottom end of the static die assembly, a punching head is fixedly installed at the bottom end of the upper end cover, sleeves are fixedly installed on both sides of the punching head, and a positioning telescopic mechanism is arranged at the top end of the base;

[0006] The positioning and telescopic mechanism includes a rotating groove, a rotating shaft, a screw and a positioning guide column. The rotating groove is opened inside the base, the rotating shaft passes through one side of the inner wall of the rotating groove, and the outer wall of the rotating shaft is rotatably connected to the base through a bearing 1. A bevel gear 1 is fixedly installed at one end of the rotating shaft, the screw passes through the top end of the inner wall of the rotating groove, and the outer wall of the screw is rotatably connected to the base through a bearing 2. A bevel gear 2 is fixedly installed at the bottom end of the screw, and the bevel gear 1 is meshed with the bevel gear 2. The positioning guide column is threadedly sleeved on the outer wall of the screw, and a connecting plate is fixedly installed on the outer wall of the positioning guide column, and a limiting rod is fixedly installed on the bottom end of the connecting plate. A rod hole is opened between the top end of the base and the rotating groove, and the limiting rod movably passes through the rod hole.

[0007] Preferably, the number of the connecting plate and the rod hole are both two, and the limiting rod is adapted to the rod hole. By providing the limiting rod, a limiting effect can be exerted on the positioning guide column to prevent the positioning guide column from rotating with the screw rod, thereby ensuring the normal movement of the positioning guide column.

[0008] Preferably, the positioning guide column is matched with the sleeve.

[0009] Preferably, a groove is provided at the top of the base, and the groove is arranged around the static mold assembly.

[0010] Preferably, oil outlet pipes are provided on both sides of the base and connected to the groove.

[0011] Preferably, a rotating plate is fixedly mounted on the other end of the rotating shaft. By providing the rotating plate, it is convenient for personnel to rotate the rotating shaft through the rotating plate, thereby facilitating operation.

[0012] The utility model provides an automatic fixing and positioning punching device. The automatic fixing and positioning punching device has the following beneficial effects:

[0013] (1) The automatic fixing and positioning punching device can calibrate the position between the positioning guide column and the sleeve in advance by setting a positioning telescopic mechanism. If an offset occurs, the base is moved as a whole for adjustment to ensure the accuracy of the position of the positioning guide column, thereby ensuring the positioning and reinforcement effect of the positioning guide column on the punch head, avoiding the offset between the positioning guide column and the sleeve. The punch head drives the sleeve to collide with the positioning guide column during the punching process, resulting in the offset of the punching position of the punch head, affecting the accuracy of the punching shape. This solves the problem that in the prior art solution, if a cylinder is used to drive the positioning guide column to move upward to calibrate the sleeve position in advance, the personnel may not be able to control the start and stop of the cylinder in a timely manner, and the force of the cylinder to drive the positioning guide column to move upward is relatively large. If there is a deviation in the position of the positioning guide column and the calibration sleeve, it may cause a collision between the positioning guide column and the calibration sleeve, causing deformation, thereby affecting the subsequent normal fixing and positioning accuracy;

[0014] (2) The automatic fixed positioning punching device can collect the lubricating oil during the punching process by setting the groove, so as to prevent the lubricating oil from flowing under the base and making it difficult for personnel to clean it. In addition, by setting the oil outlet pipe, the lubricating oil collected in the groove can be taken out through the oil outlet pipe, which is convenient for personnel to operate.

[0023] Embodiment 1:

[0024] The automatic positioning punching device provided by the utility model is preferably implemented as follows Figures 1 to 4 As shown: the automatic fixed positioning punching device comprises a punching rod 1 and a static die assembly 6. An upper end cover 2 is fixedly mounted on the bottom end of the punching rod 1. The static die assembly 6 is arranged below the lower end cover. A base 5 is fixedly mounted on the bottom end of the static die assembly 6. A punching head 3 is fixedly mounted on the bottom end of the upper end cover 2. Sleeves 4 are fixedly mounted on both sides of the punching head 3. A positioning telescopic mechanism 7 is arranged on the top end of the base 5.

[0025] The static die assembly 6 is a patented device for automatically fixing and positioning stamping parts, and the patent number is CN216937987U, so it is not described and drawn in detail in this article and the drawings;

[0026] The positioning telescopic mechanism 7 includes a rotating groove 701, a rotating shaft 702, a screw rod 705 and a positioning guide column 706. The rotating groove 701 is arranged inside the base 5. The rotating shaft 702 passes through one side of the inner wall of the rotating groove 701, and the outer wall of the rotating shaft 702 is rotatably connected to the base 5 through a bearing 1. A bevel gear 1 703 is fixedly installed at one end of the rotating shaft 702. The screw rod 705 passes through the top of the inner wall of the rotating groove 701, and the outer wall of the screw rod 705 is rotatably connected to the base 5 through a bearing 2. A bevel gear 2 704 is fixedly installed at the bottom end of the screw 705. The bevel gear 1 703 is meshed with the bevel gear 2 704. The positioning guide column 706 is threadedly sleeved on the outer wall of the screw 705. A connecting plate 708 is fixedly installed on the outer wall of the positioning guide column 706. A limiting rod 709 is fixedly installed on the bottom end of the connecting plate 708. A rod hole 710 is provided between the top of the base 5 and the rotating groove 701, and the limiting rod 709 movably passes through the rod hole 710.

[0027] Specifically, the above technical solution is that when the automatic positioning punching device is in use, the rotating plate 707 can be rotated, the rotating plate 707 drives the rotating shaft 702 to rotate, the rotating shaft 702 drives the bevel gear 1 703 to rotate, the bevel gear 1 703 drives the bevel gear 2 704 to rotate, the bevel gear 2 704 drives the screw 705 to rotate, and the screw 705 drives the positioning guide column 706 to move upward, and the position between the positioning guide column 706 and the sleeve 4 is calibrated in advance. If an offset occurs, the mobile base 5 is adjusted as a whole to ensure the accuracy of the position of the positioning guide column 706, thereby ensuring the positioning and reinforcement effect of the positioning guide column 706 on the punching head 3, avoiding the positioning guide column 706 and the sleeve 4. The punch head 3 causes the sleeve 4 to collide with the positioning guide column 706 during the stamping process, resulting in a deviation in the stamping position of the punch head 3, affecting the accuracy of the stamping shape. This solves the problem that in the prior art solution, if a cylinder is used to drive the positioning guide column 706 to move upward to calibrate the position of the sleeve 4 in advance, the personnel may not be able to control the start and stop of the cylinder in a timely manner, and the force of the cylinder to drive the positioning guide column 706 to move upward is large. If there is a deviation in the position of the positioning guide column 706 and the calibration sleeve 4, a collision may occur between the positioning guide column 706 and the calibration sleeve 4, causing deformation, thereby affecting the subsequent normal reinforcement and positioning accuracy.

[0028] Furthermore, the number of the connecting plate 708 and the rod hole 710 are both two, and the limiting rod 709 is adapted to the rod hole 710;

[0029] The limiting rod 709 can limit the positioning guide post 706 , thereby preventing the positioning guide post 706 from rotating along with the screw rod 705 , thereby ensuring the normal movement of the positioning guide post 706 .

[0030] Furthermore, the positioning guide column 706 is adapted to the sleeve 4 .

[0031] Furthermore, a rotating plate 707 is fixedly mounted on the other end of the rotating shaft 702;

[0032] Among them, by providing the rotating plate 707, it is convenient for personnel to rotate the rotating shaft 702 through the rotating plate 707, thereby facilitating personnel operation.

[0035] Specifically, the above technical solution is that by setting the groove 8, it can collect the lubricating oil during the stamping process to a certain extent, preventing the lubricating oil from flowing under the base 5, which makes it difficult for personnel to clean, and by setting the oil outlet pipe 9, the lubricating oil collected in the groove 8 can be taken out through the oil outlet pipe 9, which is convenient for personnel to operate.
