Description

Technical Field

[0001] This utility model relates to the field of deep hole enlargement technology for parts, and in particular to a deep hole enlargement device for parts processing. Background Technology

[0002] In the machining process, workpieces that have already been drilled are often enlarged. Sometimes, it is necessary to enlarge the bottom of the deep hole to make the diameter at the bottom of the deep hole larger and the diameter at the top of the deep hole smaller.

[0003] The existing patent, CN110405281B, discloses a hole-reaming device for deep holes. This patent can directly ream holes in the deep holes of workpieces. The hole-reaming range is adjusted by pneumatic transmission, which is stable and does not affect the accuracy of the deep hole. During hole reaming, the rotation of the cutting tool and the workpiece are reversed, which increases the relative speed between the cutting tool and the workpiece and saves energy resources.

[0004] In their daily work, the inventors discovered that the aforementioned hole-reaming device for deep holes clamps and fixes the workpiece using a spring in conjunction with a clamping plate. However, using a spring for clamping and fixing results in the workpiece vibrating during hole reaming because the spring is a force-bearing component rather than an active force-applying component. It can only exert a reaction force along its axial direction and cannot apply a reaction force in the circumferential direction. This causes the clamping plate to loosen easily during hole reaming, further leading to workpiece displacement. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing deep hole reaming devices use springs and clamping plates to clamp and fix workpieces. However, using springs for clamping and fixing results in the workpiece vibrating during reaming because the spring is a force-bearing component rather than an active force-applying component. It can only exert a reaction force along its axis and cannot apply a reaction force in the circumferential direction. This causes the clamping plate to loosen easily during reaming, leading to workpiece displacement. Therefore, this invention proposes a deep hole reaming device for parts processing.

The mounting base 202 is driven to move inside the slide groove 201 through the hinge plate 210. The movement of the mounting base 202 inside the slide groove 201 drives the L-shaped plate 203 and the clamping plate 204 to move. Thus, the clamping plate 204 is used to clamp and fix the workpiece 6. No spring 36 is used during the clamping process, so that the clamping plate 204 can stably clamp the workpiece 6 and improve the clamping effect of the clamping plate 204.

[0032] Reference Figure 1-5 As shown in this embodiment: the mounting base 202 is slidably connected to the sliding groove 201 via the hinge plate 210, and the clamping plate 204 has a "U" shaped structure.

The setting of the cylinder 11 has the effect of driving the long strip plate 10 to move inside the strip groove 9.

[0034] Reference Figure 1-3 As shown in this embodiment: a second motor 12 is fixedly installed on the bottom surface of the long strip 10, a round rod 13 is fixedly installed on the output end of the second motor 12, a second electric telescopic rod 14 is fixedly installed on both sides of the outer wall surface of the round rod 13, and a cutter head 15 is fixedly installed on the output end of the second electric telescopic rod 14. The setting of the second electric telescopic rod 14 has the effect of driving the cutter head 15 to move.

[0035] Reference Figure 2-4 As shown in this embodiment: a limiting device 3 is provided on one side surface of the mounting base 202. The limiting device 3 includes a slide rod 31, which is fixedly installed on one side surface of the mounting base 202. A displacement plate 32 is slidably connected to the surface of the slide rod 31. The slide rod 31 allows the displacement plate 32 to move. A limiting rod 33 is fixedly installed on the surface of the displacement plate 32. A limiting hole 34 is opened on one side surface of the L-shaped plate 203. The limiting rod 33 and the limiting hole 34 limit the L-shaped plate 203 inside the mounting base 202. A limiting plate 35 is fixedly installed on the end surface of the slide rod 31 away from the mounting base 202. A spring 36 is fixedly installed between the limiting plate 35 and the displacement plate 32. The spring 36 limits the position of the displacement plate 32 on the surface of the slide rod 31.

[0036] Working principle: When the device is needed, first place the workpiece 6 on the surface of the support plate 5, then simultaneously activate the two first electric telescopic rods 209. The activation of the first electric telescopic rods 209 drives the moving plate 208 to move on the surface of the vertical rod 207. The movement of the moving plate 208 on the surface of the vertical rod 207 drives the hinge plate 210 to move. The movement of the hinge plate 210 pushes the mounting base 202 to move inside the slide groove 201. The movement of the mounting base 202 inside the slide groove 201 drives the L-shaped plate 203 to move. The movement of the L-shaped plate 203 drives the clamping plate 204 to move. The clamping plate 204 clamps and fixes the workpiece 6. After the workpiece 6 is clamped and fixed, The cylinder 11 is started, which drives the long strip 10 to move inside the slot 9. The movement of the long strip 10 inside the slot 9 drives the second motor 12 to move. The movement of the second motor 12 drives the round rod 13 to move. The movement of the round rod 13 drives the second electric telescopic rod 14 and the cutter head 15 to move. When the cutter head 15 moves to the bottom of the machining hole 7, the cylinder 11 is closed. Then the second electric telescopic rod 14 is started, which drives the cutter head 15 to move. When the cutter head 15 moves to a position that fits against the inner wall of the machining hole 7, the second electric telescopic rod 14 is closed. Then the first motor 4 and the second motor 12 are started. The two motors 12 drive in opposite directions. At this time, the first motor 4 starts, driving the round rod 13 to rotate. The rotation of the round rod 13 drives the cutter head 15 to rotate. Simultaneously, the first motor 4 starts, driving the support plate 5 to rotate. The rotation of the support plate 5 drives the workpiece 6 to rotate, thereby increasing the relative speed between the cutter head 15 and the workpiece 6, saving energy. During the rotation of the cutter head 15, the inner diameter of the machining hole 7 continuously increases, completing the corresponding hole enlargement operation. When it is necessary to change the clamping plate 204 to the appropriate size according to the size of the workpiece 6, firstly, the sliding displacement plate 32 is slid, causing the displacement plate 32 to move on the surface of the slide rod 31. The movement of the displacement plate 32 on the surface of the slide rod 31 will compress the spring 36. This causes the spring 36 to be compressed, and at the same time, the movement of the displacement plate 32 on the surface of the slide rod 31 also drives the limit rod 33 to move. The movement of the limit rod 33 causes it to move out of the limit hole 34. The separation of the limit rod 33 and the limit hole 34 causes the L-shaped plate 203 to lose its limit inside the mounting base 202. At this time, the L-shaped plate 203 can be pulled out from the inside of the mounting base 202, completing the disassembly of the clamping plate 204. Then, a new clamping plate 204 can be replaced. This allows the device to replace the clamping plate 204 of the corresponding size according to the size of the workpiece 6, so as to achieve the purpose of clamping and fixing different sizes of workpiece 6 and improving the adaptability of the device.
