DETAILED DESCRIPTION

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of the application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0021] Reference Figure 1-Figure 3 A punching device for oil cylinder processing comprises a bottom plate 1, a fixing column 2 is fixed to the upper surface of the bottom plate 1 by bolts, a punching assembly is arranged on one side of the fixing column 2, two connecting plates 8 are fixed to the upper surface of the bottom plate 1 by bolts, springs 10 are welded to the opposite sides of the two connecting plates 8, a slide plate 14 is welded to one end of the spring 10, a clamping block 9 is fixed to one side of the slide plate 14 by bolts, a fixing assembly for limiting the slide plate 14 is arranged on the top of the two connecting plates 8, a telescopic component for horizontally moving the slide plate 14 is arranged on the opposite side of the two connecting plates 8, and a plug-in assembly is arranged on one side of the slide plate 14 so that the slide plate 14 can move horizontally. After the plate 14 moves, it is positioned so that the fixing component no longer limits the slide plate 14. Since the spring 10 is in an extruded state, when the slide plate 14 is no longer fixed, the spring 10 will cause the two slide plates 14 to move toward each other, thereby causing the two clamping blocks 9 to move toward each other to clamp and fix the cylinder to be processed. Since the elastic forces of the two springs 10 are equal, the clamping blocks 9 will move synchronously. If the position of the cylinder to be processed is offset, the position of the cylinder to be processed will be corrected so that the cylinder to be processed is in the center position, thereby clamping and positioning the cylinder to be processed, so that fast positioning and punching can be performed.

[0022] The fixing assembly includes two second multi-section telescopic rods 11, which are respectively fixed to the tops of the two connecting plates 8 by bolts. A latch 12 is fixed to one end of the telescopic portion of the two second multi-section telescopic rods 11 by bolts. A socket 13 is provided at the top of the slide plate 14, and the latch 12 is plugged into the socket 13. When the latch 12 is pulled upward, the latch 12 will lengthen the second multi-section telescopic rod 11 and disengage from the socket 13, and the slide plate 14 will no longer be fixed at this time.

[0023] In the utility model, the punching assembly includes a linear motor 3, which is arranged on one side of the fixed column 2, a fixed plate 4 is fixed to one side of the linear motor 3 by bolts, a motor is fixed to the upper surface of the fixed plate 4 by bolts, one end of the motor output shaft passes through the fixed plate 4 and is fixed to a drill bit 5 by bolts, the height of the drill bit 5 is adjusted by the linear motor 3, and then the drill bit 5 is driven by the motor to rotate to punch a hole in the oil cylinder to be processed;

[0024] In particular, the plug-in assembly includes a connecting block 17, which is welded to one side of the slide plate 14. A sliding hole is provided on the top of the connecting block 17, in which a sliding rod 16 is slidably connected. A wedge block 18 is welded to the bottom end of the sliding rod 16. A plurality of grooves 6 are provided on the upper surface of the bottom plate 1, and the wedge block 18 is plugged into the grooves 6. During the movement of the slide plate 14, the sliding rod 16 is driven to move by the connecting block 17, and the sliding rod 16 drives the wedge block 18 to move. During the movement of the wedge block 18, the groove 6, the inclined surface of the wedge block 18 and gravity cause the wedge block 18 to reciprocate up and down until the clamping block 9 clamps the oil cylinder, at which time the wedge block 18 is stuck. The slide bar 16 is inserted into the groove 6, thereby fixing the position of the slide plate 14, so that the clamping block 9 can stably clamp the oil cylinder, and a counterweight block 15 is welded to the top of the slide bar 16, and the counterweight block 15 can increase the weight of the wedge block 18. The telescopic component is two first multi-section telescopic rods 7, and the two first multi-section telescopic rods 7 are respectively fixed to the opposite sides of the two connecting plates 8 by bolts, and one end of the telescopic part of the two first multi-section telescopic rods 7 is fixed to the slide plate 14. The slide plate 14 will stretch the first multi-section telescopic rod 7 during the movement, so that the rod is moved horizontally under the action of the first multi-section telescopic rod 7, and the top of the latch 12 is fixed with a pull ring for pulling the latch 12 to move by bolts.

[0025] Working principle: when it is needed, place the oil cylinder to be processed between the two clamping blocks 9, and then pull the latch 12 to move upward, the latch 12 will lengthen the second multi-section telescopic rod 11 and disengage from the socket 13, and the slide plate 14 will no longer be fixed at this time. Since the spring 10 is in a squeezed state, when the slide plate 14 is no longer fixed, the spring 10 will make the two slide plates 14 move toward each other, so that the two clamping blocks 9 move toward each other to clamp and fix the oil cylinder to be processed. Since the elastic forces of the two springs 10 are equal, the clamping blocks 9 will move synchronously. If the position of the oil cylinder to be processed is offset, the position of the oil cylinder to be processed will be corrected. The oil cylinder to be processed is placed in the center position, so that the oil cylinder to be processed can be clamped and positioned, so that fast positioning and punching can be performed, which improves the punching accuracy of the punching device. During the movement of the slide plate 14, the connecting block 17 will drive the slide bar 16 to move, and the slide bar 16 will drive the wedge block 18 to move. During the movement of the wedge block 18, the groove 6, the inclined surface of the wedge block 18 and gravity will cause the wedge block 18 to reciprocate up and down until the clamp block 9 clamps the oil cylinder. At this time, the wedge block 18 is stuck in the groove 6, thereby fixing the position of the slide plate 14, so that the clamp block 9 can stably clamp the oil cylinder.
