Abstract
Description
Technical Field
[0001] This invention relates to the field of stamping equipment technology, and in particular to a filter cap stamping equipment. Background Technology
[0002] The oil filter is located in the engine lubrication system. Its function is to filter out harmful impurities from the engine oil coming from the oil pan, so that clean oil can be supplied to moving parts such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, thereby providing lubrication, cooling, and cleaning, and extending the life of these parts.
[0003] Among them, a filter cap stamping device with patent number CN222491668U is used to provide a stamping device that allows for easy replacement of the stamping head. However, this device has the following defects when in use: the box and ring and other components used to lock and fix the stamping head protrude from the outer side of the stamping head, making it easy for them to come into contact with the product or other components during subsequent stamping, thus affecting its safety or normal use. At the same time, the method of fixing the insert and stamping head by inserting multiple sets of rectangular blocks into the holes of the insert has a single contact point and a small contact surface, which cannot effectively ensure the connection stability between the outer shell and the insert and stamping head. Summary of the Invention
[0004] The purpose of this invention is to provide a filter cap stamping device.
[0005] The technical problem of this invention is mainly solved by the following technical solution:
[0006] A filter cap stamping device includes a base, a frame on top of the base, a hydraulic rod on the frame, a stud on the output shaft of the hydraulic rod, a stamping head movably mounted on the bottom of the stud, a screw hole on the top of the stamping head for insertion of the bottom end of the stud, a rectangular rod at the bottom center of the screw hole, a fixing channel at the bottom end of the stud for accommodating the rectangular rod, a magnetic connecting layer on the outer wall of the rectangular rod that is movably connected to the side wall of the fixing channel, and a screw tube located inside the screw hole fitted over the stud, with the inner and outer side walls of the screw tube respectively screwed and fixed to the corresponding stud and screw hole.
[0007] Preferably, the top end of the screw tube extends to the outer side of the top of the screw hole, and a handle is radially provided at the top end of the screw tube.
[0008] Preferably, the top of the rectangular rod is higher than the horizontal plane of the top of the stamping head, the size of the rectangular rod is adapted to the size of the fixed channel, and a plurality of receiving grooves for accommodating the corresponding magnetic connecting layer are provided on the side wall of the rectangular rod. The magnetic connecting layer is locked and fixed in the receiving groove by bolts, and one end face of the magnetic connecting layer is attached to the side wall corresponding to the fixed channel.
[0009] Preferably, the bottom of the hydraulic rod output shaft is provided with a mounting plate connected to the stud, the mounting plate is provided with a corrugated hose sleeved on the stud, and the bottom end of the corrugated hose is provided with a counterweight ring located at the top of the screw tube.
[0010] Preferably, the ratio between the length of the stud and the length of the tube is 2:1.
[0011] The beneficial effects of this invention are as follows: This invention uses a screw tube to screw the punch head and the stud together. At this time, since the side wall of the screw hole in the punch head and the stud are in large-area contact with the screw tube and are threadedly connected, the connection stability between the punch head and the stud and hydraulic rod is indirectly improved. At the same time, the screw tube and the handle are only exposed at the top of the punch head, so that they will not extend to the outside of the edge of the punch head to interfere with its normal use. Attached Figure Description

[0015] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0016] A filter cap stamping device includes a base 1, a frame 2 on the top of the base 1, a hydraulic rod 3 on the frame 2, a stud 4 on the output shaft of the hydraulic rod 3, a stamping head 5 movably mounted on the bottom of the stud 4, a screw hole 6 on the top of the stamping head 5 for inserting the bottom end of the stud 4, a rectangular rod 7 in the middle of the bottom of the screw hole 6, a fixing channel 8 at the bottom end of the stud 4 for accommodating the rectangular rod 7, and a magnetic connecting layer 9 on the outer wall of the rectangular rod 7 that is movably connected to the side wall of the fixing channel 8.
[0017] The stud 4 is also fitted with a threaded tube 10 located inside the threaded hole 6. The inner and outer side walls of the threaded tube 10 are respectively threaded and fixed to the corresponding stud 4 and threaded hole 6. The top end of the threaded tube 10 extends to the outer side of the top of the threaded hole 6, and a handle 11 is radially provided at the top end of the threaded tube 10.
[0018] like Figure 2 As shown, the top of the rectangular rod 7 is higher than the top of the stamping head 5, so that when the top of the rectangular rod 7 is inserted into the fixed channel 8 during assembly, the stamping head 5 is located below the stud 4, so that there is a gap between the stamping head 5 and the bottom of the stud 4 to provide workers with a field of vision, thereby facilitating the adjustment of the rectangular rod 7 to smoothly insert it into the fixed channel 8. The size of the rectangular rod 7 is adapted to the size of the fixed channel 8. Several receiving grooves for accommodating the corresponding magnetic connecting layer 9 are provided on the side wall of the rectangular rod 7. The magnetic connecting layer 9 is fixed in the receiving groove by bolts. One end face of the magnetic connecting layer 9 is attached to the side wall of the fixed channel 8.
[0019] In this embodiment, the bottom of the output shaft of the hydraulic rod 3 is provided with a mounting plate 12 connected to the stud 4. A corrugated hose (not shown) is provided on the mounting plate 12 and is sleeved on the stud 4. A counterweight ring (not shown) is provided at the bottom end of the corrugated hose and located at the top of the screw tube 10. The counterweight ring pulls the corrugated hose to make it expand, so that the corrugated hose covers the threads of the outer wall of the stud 4 to protect it. When it is necessary to rotate the screw tube 10 upward, the counterweight ring is slid upward on the stud 4 while compressing the corrugated hose, so that the screw tube 10 can move smoothly spirally upward on the stud 4.
[0020] In this embodiment, the ratio between the length of the stud 4 and the length of the screw tube 10 is 2:1. This ensures that when the screw tube 10 rotates upward within the screw hole 6 and on the stud 4, after the bottom end of the screw tube 10 slides out of the screw hole 6, it can be screwed onto the stud 4 above the stamping head 6. This prevents the stud 4 from being too short, which would prevent the screw tube 10 from rotating upwards sufficiently and exiting from the screw hole 6.
[0021] During installation, the rectangular rod 7 is inserted into the fixed channel 8, the bottom end of the stud 4 is inserted into the screw hole 6, and the screw tube 10 is located on the stud 4 above the stamping head 6. At this time, the magnetic connection layer 9 on the rectangular rod 7 is magnetically connected to the side wall of the fixed channel 8, preventing the rectangular rod 7 from sliding out of the fixed channel 8 without human intervention, and preventing the stamping head 6 from sliding off the bottom end of the stud 4. Furthermore, the way the side wall of the fixed channel 8 abuts against the side wall of the rectangular rod 7 prevents the stamping head 5 from rotating together with the screw tube 10 when the screw tube 10 is rotated downwards to connect with the screw hole 6 and the stud 4.
[0022] When the bottom end of the stud 4 is inserted into the screw hole 6, the screw tube 10 on the stud 4 is rotated downwards so that its bottom end is inserted into the screw hole 6 and continues to rotate downwards. At this time, the outer wall of the screw tube 10 is threaded to the inner wall of the screw hole 6, and the inner wall of the screw tube 10 is threaded to the outer wall of the stud 4. Finally, the bottom end of the screw tube 10 slides into the screw hole 6 and is threaded to both the screw hole 6 and the stud 4. This achieves the screw connection and fixation of the punch head 5 and the stud 4 through the screw tube 10. Since the side wall of the screw hole 6 in the punch head 5 and the stud 4 are in large-area contact with the screw tube 10 and are threadedly connected, the connection stability of the punch head 5, the stud 4, and the hydraulic rod 3 is indirectly improved. At the same time, the screw tube 10 and the handle 11 are only exposed at the top of the punch head 5, so that they do not extend to the outside of the edge of the punch head 5 to interfere with its normal use.
[0023] When replacing the stamping head 5, the screw tube 10 rotates upward on the stud 4 and rotates out from the screw hole 6. At this time, the screw hole 6 in the stamping head 5 can be slid off the bottom of the stud 4 by squeezing, and the rectangular rod 7 can be pulled out downward from the fixed channel 8. Then, the new stamping head 5 can be replaced according to the above steps.
[0024] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
