Description

Technical Field

[0001] This utility model relates to the technical field of marking devices, and in particular to a bolt marking device. Background Technology

[0002] Bolts are threaded fasteners, and marking is required on their heads during manufacturing. Chinese utility model patent CN220995907U discloses a high-efficiency bolt marking device. This device includes a base plate, a placement plate, and a connecting block. Side plates are fixed to both ends of the top surface of the base plate, and a top plate is fixed to the top surface of each side plate. A hydraulic cylinder is fixedly mounted on the top surface of the top plate. One end of a connecting rod is fixed to the output end of the piston rod of the hydraulic cylinder, and the other end of the connecting rod is fixed to a connecting plate. A mounting plate is fixed to the bottom surface of the connecting plate, and multiple marking components are provided on the bottom surface of the mounting plate. The hydraulic cylinder drives these marking components to mark multiple bolt heads. After marking, the connecting block is disassembled, the placement plate is removed, and multiple bolts are taken out. Simultaneously, another placement plate with multiple bolts is placed in, and the connecting block is fixed in place for further marking. This allows for simultaneous marking or removal of multiple bolt heads, improving work efficiency and marking efficiency.

[0003] However, after the above-mentioned marking device marks the bolts, it is necessary to disassemble the connecting block and the limiting plate to remove the placement plate containing multiple bolts, and then remove all the bolts. The operation of picking up and putting down bolts is relatively complicated and is not conducive to improving work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bolt marking device that adopts dual-station loading and unloading, making bolt unloading operation simpler, faster, and improving work efficiency.

[0005] This utility model discloses a bolt marking device, comprising a base, a column, and a marking mold. The column is mounted on the base, and a hydraulic cylinder is installed on the column. The marking mold is installed at the lower end of the piston rod of the hydraulic cylinder, and multiple marking heads are provided on the lower end face of the marking mold. It also includes a slide, two positioning grooves, a support plate, and handles. The slide is horizontally slidably mounted on the base. Two positioning grooves are symmetrically arranged on the upper end face of the slide, and multiple spiral insertion components are arranged in each of the two positioning grooves. The multiple insertion components are respectively located below the multiple marking heads of the marking mold. At least two support plates are provided, and handles are provided on both sides of the support plates. The middle part of the support plate is engaged with the positioning groove, and multiple insertion holes are provided in the middle part of the support plate, which are respectively aligned with the multiple insertion components. During operation, multiple bolts are inserted into the multiple insertion holes in the middle part of the support plate. By holding the two handles, the middle part of the support plate is engaged into the positioning groove, and the multiple bolts are respectively inserted into the multiple insertion components. A sliding table moves the pallet below the marking mold. The hydraulic cylinder on the column actuates, causing the piston rod to push the marking mold downwards, allowing multiple marking heads to mark the bolt heads. During this process, another pallet filled with bolts is inserted into a positioning groove located outside the marking mold. After multiple bolts are marked, the marking mold rises and disengages from the bolts. The sliding table moves horizontally in the opposite direction, moving the marked bolts out of the marking mold. Holding two handles, the pallet containing the marked bolts is removed from the positioning groove, and the pallet is flipped over to unload the bolts quickly. New bolts are then reinstalled into the pallet's insertion holes. During this process, another positioning groove and multiple bolts on the pallet move below the marking mold for automatic marking, enabling continuous operation. Compared to existing technologies, this bolt unloading operation is simpler, faster, and improves work efficiency.

[0006] Preferably, the insertion assembly includes a square hole, a slot, a square post, and a support block. The square hole has a positioning groove at the bottom, and an outwardly expanding slot at the top. The square post is detachably inserted into the square hole, with an insertion hole in the middle and a support block at the top, which matches the slot. The square post is inserted into the square hole, and the support block is limited and supported by the slot. By setting insertion holes of different diameters on the square post, bolts of different diameters can be inserted, providing good versatility. The slot and support block work together to support the square post, improving its stability.

[0007] Preferably, it also includes a mounting frame, multiple sliders, and a slide rail. The mounting frame is mounted on the base, the multiple sliders are mounted on the mounting frame, and the slide rail is mounted on the slide table. The slide rail is slidably connected to the multiple sliders. The slidable connection between the slide rail and the multiple sliders enables the slide table to move smoothly horizontally.

[0008] Preferably, it also includes a rack, a motor, and a gear. The rack is mounted on the slide, the motor is mounted on the mounting frame, and the gear is concentrically mounted on the output shaft of the motor. The gear meshes with the rack. The motor drives the gear to rotate, and the meshing gear drives the rack to move horizontally. The rack drives the slide to move back and forth horizontally.

[0009] Preferably, it also includes multiple support blocks, with a clearance opening in the middle of the mounting frame, multiple support blocks installed on the base, multiple support blocks located in the clearance opening of the mounting frame, and multiple support blocks used to support the slide table; by setting multiple support blocks to provide auxiliary support for the slide table, the slide table is more stable and reliable when marking bolts.

[0010] Preferably, the slide also includes multiple sliding rods and multiple springs. The support block is located below the slide table and does not contact the slide table. The base is provided with multiple vertical sliding holes. The lower parts of the multiple sliding rods are slidably inserted into the multiple sliding holes of the base. The upper ends of the multiple sliding rods are connected to the mounting frame. The upper ends of the multiple springs are connected to the mounting frame, and the lower ends of the multiple springs are connected to the base. The multiple support blocks are located below the slide table and do not contact the slide table, so that the slide table slides without obstruction. When the marking mold descends to mark multiple bolts, the slide table is forced to descend, causing the mounting frame to descend, which causes the multiple sliding rods to descend into the multiple sliding holes of the base. The multiple springs are compressed, which causes the multiple support blocks to support the lower end face of the slide table. When the marking is completed, the marking mold rises and disengages from the slide table. The multiple springs return to their original position and lift the mounting frame, causing the slide table to disengage from the multiple support blocks again, so that the slide table slides without obstruction again.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, multiple bolts are inserted into multiple insertion holes in the middle of the pallet. Holding two handles, the middle of the pallet is inserted into the positioning groove, and the multiple bolts are inserted into multiple insertion assemblies. The horizontal sliding table moves the pallet below the marking mold. The hydraulic cylinder on the column actuates, causing the piston rod to push the marking mold downwards, allowing multiple marking heads of the marking mold to mark the heads of the bolts. During this process, another pallet filled with bolts is inserted into another positioning groove located outside the marking mold; once multiple bolts... After the bolts are marked, the marking mold rises and disengages from the bolts. The sliding table slides horizontally in the opposite direction, causing the multiple marked bolts to move out of the outside of the marking mold. Holding the two handles, the tray containing the marked bolts is removed from the positioning slot, and the tray is flipped over to dump out the multiple bolts together for quick unloading. Then, new bolts are reinstalled into the insertion holes of the tray. During this process, another positioning slot and multiple bolts on the tray move to the bottom of the marking mold for automatic marking, achieving continuous operation. Compared with existing technologies, the bolt unloading operation is simpler, faster, and improves work efficiency. Attached Figure Description

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a bolt marking device includes a base 1, a column 2, and a marking mold 3. The column 2 is mounted on the base 1, and a hydraulic cylinder is mounted on the column 2. The marking mold 3 is mounted on the lower end of the piston rod of the hydraulic cylinder, and multiple marking heads are provided on the lower end face of the marking mold 3.

[0021] The square column 10 is inserted into the square hole 8, and the support block 11 is limited and supported by the support groove 9. By setting different hole diameters on the square column 10, bolts of different diameters can be inserted, which has good versatility. The support groove 9 and the support block 11 work together to support the square column 10 and improve the stability of the square column 10.

[0022] During operation, multiple bolts are inserted into the holes in the center of the support plate 6. Holding the two handles 7, the center of the support plate 6 is inserted into the positioning groove 5, and the bolts are inserted into the holes of the square columns 10. The slide table 4 is slid horizontally, moving the support plate 6 below the marking mold 3. The hydraulic cylinder on the column 2 actuates, causing the piston rod to push the marking mold 3 downwards, allowing the multiple marking heads of the marking mold 3 to mark the bolt heads. During this process, another support plate 6 filled with bolts is inserted into another positioning groove 5 located outside the marking mold 3. After the multiple bolts are marked, The marking mold 3 is raised and disengaged from the bolts. The sliding table 4 slides horizontally in the opposite direction, causing the multiple bolts that have been marked to move out of the outside of the marking mold 3. Holding the two handles 7, the tray 6 containing the marked bolts is taken out from the positioning groove 5, and the tray 6 is flipped over to pour out the multiple bolts on it together for quick unloading. Then, the new bolts are reinstalled into the insertion hole of the tray 6. During this process, the other positioning groove 5 and the multiple bolts on the tray 6 move to the bottom of the marking mold 3 for automatic marking, realizing continuous operation. Compared with the existing technology, the bolt unloading operation is simpler and faster, improving work efficiency. Example 2

[0023] like Figures 1 to 5As shown, based on Embodiment 1, it further includes a mounting frame 12, multiple sliders 13, and a slide rail 14. The mounting frame 12 is mounted on the base 1, the multiple sliders 13 are mounted on the mounting frame 12, and the slide rail 14 is mounted on the slide table 4, with the slide rail 14 slidably connected to the multiple sliders 13. It also includes a rack 15, a motor 16, and a gear 17. The rack 15 is mounted on the slide table 4, the motor 16 is mounted on the mounting frame 12, and the output shaft of the motor 16 is concentrically mounted with the gear 17, which meshes with the rack 15. It also includes multiple support blocks 18, with a clearance provided in the middle of the mounting frame 12. The system includes multiple support blocks 18 mounted on the base 1, located in the clearance opening of the mounting frame 12, and used to support the slide table 4; it also includes multiple slide rods 19 and multiple springs 20. The support blocks 18 are located below the slide table 4 and do not contact the slide table 4. The base 1 is provided with multiple vertical sliding holes. The lower parts of the multiple slide rods 19 are slidably inserted into the multiple sliding holes of the base 1, the upper ends of the multiple slide rods 19 are connected to the mounting frame 12, the upper ends of the multiple springs 20 are connected to the mounting frame 12, and the lower ends of the multiple springs 20 are connected to the base 1.

[0024] The slide rail 14 is slidably connected to multiple sliders 13, allowing the slide table 4 to move smoothly horizontally. The motor 16 drives the gear 17 to rotate, and the gear 17 meshes with and drives the rack 15 to move horizontally. The rack 15 drives the slide table 4 to move back and forth horizontally. Multiple support blocks 18 are located below the slide table 4 and do not contact the slide table 4, so that the slide table 4 can slide without obstruction. When the marking mold 3 descends to mark multiple bolts, the slide table 4 is forced to lower the mounting frame 12, causing multiple slide rods 19 to descend into multiple sliding holes in the base 1. Multiple springs 20 are compressed, so that multiple support blocks 18 support the lower end face of the slide table 4. By setting multiple support blocks 18 to provide auxiliary support for the slide table 4, the slide table 4 is more stable and reliable when marking bolts. After the marking is completed, the marking mold 3 rises and disengages from the slide table 4. The multiple springs 20 return to their original state and support the mounting frame 12, so that the slide table 4 disengages from the multiple support blocks 18 again, so that the slide table 4 can slide without obstruction again.

Holding two handles 7, the center of the support plate 6 is inserted into the positioning groove 5, and the bolts are then inserted into the holes of multiple square columns 10. Next, a motor 16 drives a gear 17 to rotate. The gear 17 meshes with and drives a rack 15 to move horizontally. The rack 15 drives a slide table 4 to slide horizontally, moving the support plate 6 below the marking mold 3. The hydraulic cylinder on the column 2 actuates, causing the piston rod to push the marking mold 3 downwards, allowing multiple marking heads of the marking mold 3 to mark the bolt heads. During marking, multiple support blocks 18 support the slide table 4. Then, during this process, another tray 6 filled with bolts is inserted into another positioning groove 5 located outside the marking mold 3. After multiple bolts are marked, the marking mold 3 is raised to detach from the bolts, and the slide table 4 slides horizontally in the opposite direction, so that the multiple bolts that have been marked are moved out of the outside of the marking mold 3. Holding the two handles 7, the tray 6 containing the marked bolts is taken out from the positioning groove 5, and the tray 6 is flipped over to pour out the multiple bolts on it together for quick unloading. Finally, the new bolts are reinstalled into the insertion hole of the tray 6. During this process, the other positioning groove 5 and the multiple bolts on the tray 6 move to the bottom of the marking mold 3 for automatic marking, so as to achieve continuous operation.
