Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of maintenance of numerical control turret punch press equipment, in particular to a pin sleeve disassembly device for a numerical control turret punch press. Background Art
[0002] CNC turret punch press is a machine tool that is widely used in the field of sheet metal processing. The turret is the component with the highest precision requirement on the CNC turret punch press. In order to ensure the durability of the turret, a steel sleeve is installed on the positioning hole (latch hole) of the turret, which is the latch sleeve. During long-term use, the latch sleeve will inevitably wear and damage, which will increase the positioning accuracy error of the turret, causing the mold and product to be scrapped during use, causing great economic losses to users.
[0003] When assembling the turret mechanism, the latch sleeve is glued to the positioning hole of the turret using Loctite 609 glue. After the high-strength glue is set, the turret and the latch sleeve are bonded together. The bonding strength is very high, and there is almost no good way to separate the two.
[0004] After nearly 30 years of development, there are a large number of punch press users in the market. Many punch presses have worn and damaged latch sleeves due to long service life, and there is a large demand for replacement of latch sleeves. Since the space of the turret positioning hole is very small, if the latch sleeve needs to be replaced, the current practice is generally to use a hammer and chisel to forcibly break the latch sleeve, and then take the fragments out of the positioning hole and clean them before installing a new latch sleeve. The process is time-consuming and labor-intensive, and it is easy to damage the turret, affecting the accuracy of the turret and causing irreparable losses. Summary of the invention
[0005] The purpose of the utility model is to solve the problems existing in the prior art and to provide a pin sleeve disassembly device for a CNC turret punch press.
[0006] The specific scheme of the utility model is: a pin sleeve disassembly device for a CNC turret punch press, comprising a support frame, a pull rod, a nut, two hooks and a connecting pin, a through hole is provided on the top of the support frame, a connecting portion is provided on the upper end of the hook, a pin hole is provided on the connecting portion, a slot is provided on the lower end of the hook, the length of the slot is greater than the length of the pin sleeve, and a stopper is provided on the bottom end of the slot; a plug plate is provided on the lower end of the pull rod, a pin hole matching the hook is provided on the plug plate, an external thread is provided on the upper end of the pull rod, the external thread matches the nut, and the diameter of the through hole is greater than the pull rod and smaller than the nut.
[0007] Furthermore, the shape of the slot is arc-shaped.
[0008] Furthermore, the support frame includes two support legs, a horizontal support plate is provided on the top of the two support legs, and the through hole is provided on the support plate.
[0009] Furthermore, the bottom end of the plug board is provided with a chamfer.

[0018] See also Figure 1-5 The present embodiment is a device for removing the latch sleeve 6 of a CNC turret punch press, comprising a support frame 3, a pull rod 1, a nut 2, two hooks 4 and a connecting pin 5. A through hole is provided on the top of the support frame 3, a connecting portion is provided on the upper end of the hook 4, and a pin hole 41 is provided on the connecting portion. A slot 42 is provided on the lower end of the hook 4, and the length of the slot 42 is greater than the length of the latch sleeve 6. A stopper 43 is provided on the bottom end of the slot 42; a plug plate 11 is provided on the lower end of the pull rod 1, and a pin hole 41 matching the hook 4 is provided on the plug plate 11; an external thread 12 is provided on the upper end of the pull rod 1, and the external thread 12 matches the nut 2. The diameter of the through hole is greater than the pull rod 1 and smaller than the nut 2.
[0019] Furthermore, the shape of the slot 42 is arc-shaped.
[0020] Furthermore, the support frame 3 includes two support legs, a horizontal support plate is provided on the top of the two support legs, and the through hole is provided on the support plate.
[0021] Furthermore, the bottom end of the plug board 11 is chamfered.
[0022] Furthermore, the hardness of the portion where the stopper 43 contacts the latch sleeve 6 is HRC62-64.
[0023] When the utility model is in operation, the operation method is as follows: first, clean the oil and debris on the inner wall of the latch sleeve 6 that needs to be disassembled, and then put the two hooks 4 symmetrically into the holes of the latch sleeve 6, so that the slots 42 of the two hooks 4 are pushed to the position of fitting the inner wall of the latch sleeve 6, and at this time there will be a gap between the two hooks 4; insert the plug plate 11 of the pull rod 1 into the gap until it is inserted to the bottom so that the pin hole 41 of the plug plate 11 is aligned with the pin holes 41 of the two hooks 4, and then insert the φ8×30 connecting pin 5 into the pin hole 41 to connect the two hooks 4 and the plug plate 11 together; place the support frame 3 from top to bottom just above the latch sleeve 6, the two supporting feet of the support frame 3 are in contact with the turret 7, and the pull rod 1 passes through the through hole of the support frame 3; put the nut 2 on the top of the pull rod 1, and rotate the nut 2 clockwise by hand. Using the principle of thread, when the two threads of the pull rod 1 and the nut 2 rotate relative to each other, they will advance or retreat along the axial direction of the thread.
[0024] Twist the nut 2 clockwise, and as the nut 2 is gradually tightened, the pull rod 1 will rise along the axis, and drive the hooks 4 on both sides to rise together through the connecting pin 5; the hooks 4 will gradually hook the two sides of the latch sleeve 6; finally, continue to tighten the nut 2 with an adjustable wrench, and the force applied by the wrench is transmitted to the latch sleeve 6 through the nut 2, the pull rod 1, and the hook 4, forcibly tearing the glue between the latch sleeve 6 and the turret 7; continue to tighten the nut 2 clockwise, and the latch sleeve 6 is pulled to continue to rise until the latch sleeve 6 and the turret 7 are completely separated. At this point, the work of quickly disassembling the latch sleeve 6 of the CNC turret 7 punch turret 7 is completed.
