Description

Technical Field

[0001] This utility model relates to the field of marking machines, specifically a pressure bowl protective component for a straight tube pressure bowl marking machine. Background Technology

[0002] A steel stamping machine is a machine that uses mechanical means to replace manual pressing of steel stamps. It is generally used to stamp various numbers and marks on various steel workpieces and has a very wide range of applications.

[0003] The invention patent with publication number CN207072191U discloses a multi-functional integrated machine for stamping steel numbers on electric vehicle frames. This machine includes a clamping device, a lower bearing cup conveying device, a manual adjustment mechanism, a linear module, and a striking digital model assembly. The clamping device uses a pneumatic-hydraulic booster cylinder, reducing the size of the equipment and making maintenance convenient, clean, and safe. Its built-in grease injection mechanism can perform grease injection while positioning. Furthermore, the stamping method involves directly striking the digital model. The linear module and the striking digital model assembly are controlled by three servo motors, achieving functions such as digital alignment, automatic striking of the digital model, and automatic adjustment of the frame striking position, fully automating the digital model stamping process. The frame number printed by this device conforms to national standards in depth, is easy to trace, and cannot be altered. The deformation of the frame tube is minimal, not affecting the overall strength of the frame. It also allows for the entire frame to be sent to the factory before the frame number is stamped, avoiding problems such as sending the frame to the wrong manufacturer or mismatched barcodes and frame numbers.

[0004] In existing marking machines, the operator needs to hold the frame and use a hydraulic rod to press the fixed cup into the straight tube when the frame is in a vertical position. When the straight tube of the frame is tilted, the pressing head will not be able to accurately press the fixed cup into the straight tube, which will affect the pressing accuracy and also damage the fixed cup and the pressing head. To solve the above problems, this application proposes a pressing cup protection component for a straight tube pressing cup marking machine. Utility Model Content

[0031] The guide rod 8 is slidably provided with a protective sleeve 10, and the bottom of the protective sleeve 10 is threadedly connected to a top positioning bushing 12.

[0032] It should be noted that the bottom of the straight tube is inserted into the bottom positioning shaft 6 on the surface of the three-jaw chuck 4. When the clamping handwheel 5 is rotated, it can drive the jaws on the three-jaw chuck 4 to clamp the outer wall surface of the straight tube. The fixed cup is sleeved on the pressure head 9 through the placement groove 13. The lifting pedal switch 14 controls the extension of the hydraulic push rod 7. The bottom of the piston rod is connected to the guide rod 8. The guide rod 8 pushes the pressure head 9 down. The top positioning shaft sleeve 12 at the bottom of the protective sleeve 10 first contacts the top of the straight tube and puts the top positioning shaft sleeve 12 on the top of the straight tube. It can achieve precise positioning of the top and bottom of the straight tube at the same time during use. The piston rod continues to push the pressure head 9 down through the guide rod 8. At this time, the compression spring 11 is stretched. The pressure head 9 presses the fixed cup into the inner cavity of the straight tube, which can improve the pressing accuracy of the straight tube and improve the protection of the fixed cup and the pressure head 9.

[0033] In this embodiment, as Figure 3 As shown, the side wall of the three-jaw chuck 4 is connected to a clamping handwheel 5 via a drive shaft, and the clamping handwheel 5 is located on the side wall surface of the machine body 1.

[0034] It should be noted that when the clamping handwheel 5 is rotated, it can drive the jaws on the three-jaw chuck 4 to clamp onto the outer wall surface of the straight pipe, which can easily fix the bottom of the straight pipe.

[0035] In this embodiment, as Figure 4 As shown, rubber pads are provided on the surface of the jaws of the three-jaw chuck 4 and the inner wall surface of the top positioning bushing 12.

[0036] It should be noted that the gripper and top positioning bushing 12 can improve the protection of both ends of the straight tube when positioning them.

[0037] In this embodiment, as Figure 3 As shown, a compression spring 11 is sleeved on the surface of the guide rod 8.

[0043] The working principle and usage process of this utility model: The bottom of the straight pipe is inserted into the bottom positioning shaft 6 on the surface of the three-jaw chuck 4. When the clamping handwheel 5 rotates, it drives the jaws on the three-jaw chuck 4 to clamp onto the outer wall surface of the straight pipe. The fixing bowl is sleeved on the pressure head 9 through the placement groove 13. The lifting pedal switch 14 controls the extension of the hydraulic push rod 7. The bottom of the piston rod is connected to the guide connecting rod 8. The guide connecting rod 8 pushes the pressure head 9 down. The top positioning shaft sleeve 12 at the bottom of the protective sleeve 10 first contacts the top of the straight pipe and makes the top positioning shaft sleeve 12 sleeved on the top of the straight pipe. It can achieve precise positioning of the top and bottom of the straight pipe at the same time during use. The piston rod continues to push the pressure head 9 down through the guide connecting rod 8. When the compression spring 11 is stretched, the pressure head 9 presses the fixed cup into the inner cavity of the straight tube, which can improve the pressing accuracy of the straight tube and improve the protection of the fixed cup and the pressure head 9. The gripper surface of the three-jaw chuck 4 and the inner wall surface of the top positioning bushing 12 are provided with rubber pads. When the gripper and the top positioning bushing 12 are positioning the two ends of the straight tube, they can improve the protection of the two ends of the straight tube. The pressure head 9, the bottom positioning shaft 6 and the top positioning bushing 12 are fixed to the guide rod 8, the three-jaw chuck 4 and the protective sleeve 10 respectively by threaded connection, which can facilitate quick disassembly and assembly of the pressure head 9, the bottom positioning shaft 6 and the top positioning bushing 12 so as to meet the pressing operation of different models of straight tubes during use.
