DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described in conjunction with specific implementation manners.

[0022] Please refer to Figures 1 to 4 The utility model provides a technical scheme: a machining tool for hydraulic valve core handle part thread, including base 1, base 1 top end is provided with moving assembly 2, moving assembly 2 top end is provided with support frame 3, and support frame 3 side is provided with tool changing assembly 4;

[0023] Tool changing assembly 4 includes the tool changing motor 41 of fixed connection in one side of support frame 3, and the output end of tool changing motor 41 is fixedly connected with rotating rod 42, and rotating rod 42 surface is fixedly connected with tool changing disc 43, and tool changing disc 43 surface is provided with a plurality of guide holes 44, and guide hole 44 is slidably connected with mounting seat 45, and mounting seat 45 surface is sleeved with reset spring 46, and mounting seat 45 is screw connected with tool 47, and one side of support frame 3 is fixedly connected with electric push rod 48 below tool changing motor 41.

[0024] The handle of the hydraulic valve core can be machined by the tool 47. During the machining process, when the tool 47 needs to be switched, the corresponding tool 47 installed in the mounting seat 45 is rotated by the tool changing motor 41, the rotating rod 42 and the tool changing disc 43 until the tool changing disc 43 is at the bottom, and the switching of the tool 47 is completed. The length of the tool 47 extending out can be adjusted according to the length of the hydraulic valve core to be machined by the electric push rod 48, the guide hole 44 and the reset spring 46. The end of the tool 47 close to the mounting seat 45 is provided with a positive thread, and the tool 47 can be disassembled and replaced by rotating the tool 47 to completely separate the tool 47 from the mounting seat 45.

[0025] Further, the mounting seat 45 is provided with a slot 7 close to the support frame 3, and the output end of the electric push rod 48 extending out of the support frame 3 is fixedly connected with a plug 8. During the adjustment of the length of the tool 47 extending out, the electric push rod 48 will be started and drive the plug 8 connected thereto to be inserted into the slot 7 provided on one side of the mounting seat 45, thereby preventing the electric push rod 48 from slipping on the surface of the mounting seat 45.

[0026] Please refer to Figure 2 , as an embodiment of the utility model: the moving assembly 2 includes two fixed plates 21 fixedly connected to the top end of the base 1, the opposite sides of the two fixed plates 21 are rotatably connected with lead screws 22, one end of the lead screw 22 extending out of the fixed plate 21 is fixedly connected with a moving motor 23, the opposite sides of the two fixed plates 21 are fixedly connected with limit rods 24 on one side of the lead screw 22, the limit rod 24 is slidably connected with a moving seat 25 on the surface, the moving seat 25 is screwedly connected with the lead screw 22, and the moving seat 25 is fixedly connected with the support frame 3.

[0027] The support frame 3 connected to the top end of the moving seat 25 is driven to move by the moving motor 23, the lead screw 22, the fixed plate 21 and the limit rod 24, so that the tool 47 is close to the hydraulic valve core to be machined.

[0028] Please refer to Figures 1 to 3 , as an embodiment of the utility model: the support frame 3 is fixedly connected with a protective cover 5 close to the tool changing disc 43, the protective cover 5 is rotatably connected with the tool changing disc 43, the width of the protective cover 5 is greater than the length of the tool 47, and the protective cover 5 is provided with a tool outlet hole 6 on one side.

[0029] During the daily use of the tool 47, the tool 47 connected to the surface of the tool changing disc 43 can be shielded and protected by the protective cover 5. During the replacement of the tool 47, the tool changing disc 43 is rotated in the protective cover 5. When the corresponding tool 47 is rotated to the bottom of the tool changing disc 43 and faces the tool outlet hole 6, the electric push rod 48 drives the mounting seat 45 to extend out of the tool outlet hole 6, so that the protective cover 5 can provide protection for the tool 47 and will not hinder the switching of the tool 47.

[0030] Further, a plurality of guide holes 44 are arranged in a ring array around the tool changing disc 43, and the diameter of the tool outlet hole 6 is greater than that of the mounting seat 45. The arrangement of the plurality of guide holes 44 in a ring array around the tool changing disc 43 ensures that the corresponding tool 47 can be aligned with the tool outlet hole 6 when the tool changing disc 43 is rotated to the lowermost position. The diameter of the tool outlet hole 6 being greater than that of the mounting seat 45 ensures that the mounting seat 45 can be smoothly extended from the tool outlet hole 6.

[0031] Still further, the length of the rotating rod 42 is greater than that of the mounting seat 45, and the length of the mounting seat 45 is greater than the width of the protective cover 5. The length of the rotating rod 42 being greater than that of the mounting seat 45 ensures that there is a certain distance between the mounting seat 45 and the support frame 3, thereby avoiding the support frame 3 from obstructing the rotation of the tool changing disc 43. The length of the mounting seat 45 being greater than the width of the protective cover 5 ensures that the tool changing disc 43 can be smoothly rotated within the protective cover 5.

[0032] Specific implementation: the handle of the hydraulic valve core can be machined by the tool 47. In this process, when the tool 47 needs to be switched, the tool changing motor 41 will be started to rotate the rotating rod 42 connected thereto, thereby rotating the tool changing disc 43 connected to the surface of the rotating rod 42, and then rotating the corresponding tool 47 mounted in the mounting seat 45 connected to the surface of the tool changing disc 43 until the lowermost position of the tool changing disc 43, thereby completing the switching of the tool 47. Then the electric push rod 48 will be started to insert the block 8 connected thereto into the slot 7 opened on one side of the mounting seat 45, thereby pushing the mounting seat 45 to make the mounting seat 45 slide along the guide hole 44 opened on the surface of the tool changing disc 43 and press the return spring 46, so as to adjust the length of the tool 47 extending out according to the length of the hydraulic valve core to be machined. The end of the tool 47 close to the mounting seat 45 is provided with a positive thread, and the tool 47 can be disassembled and replaced by rotating the tool 47 to completely separate it from the mounting seat 45;

[0033] When the position of the tool 47 needs to be adjusted, the moving motor 23 will be started to rotate the lead screw 22 connected thereto between the two fixed plates 21 fixed to the top end of the base 1. The movement of the moving seat 25 along the surface of the lead screw 22 is limited by the limiting rod 24, thereby moving the tool 47 through the support frame 3 connected to the top end of the moving seat 25, so as to make the tool 47 close to the hydraulic valve core to be machined;

[0034] In the daily use of the tool 47, the tool 47 connected to the surface of the tool changer 43 can be shielded and protected by the protective cover 5. In the process of replacing the tool 47, the tool changer 43 will rotate inside the protective cover 5. When the corresponding tool 47 rotates to the lowermost part of the tool changer 43 and is opposite to the tool outlet hole 6 opened on the surface of the protective cover 5, the mounting seat 45 will be pushed to make the mounting seat 45 slide along the guide hole 44. Next, the mounting seat 45 will extend out of the tool outlet hole 6, so as to ensure that the protective cover 5 will not hinder the switching of the tool 47 while providing protection for the tool 47.

[0035] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
