DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0028] like Figure 1-6 As shown, the embodiment of the utility model provides a flexible hole-opening platform tooling for high-precision special-shaped parts, including a workbench 1, vertical rods 4 are fixedly installed on the four sides of the top of the workbench 1, a top plate 5 is fixedly installed on the top of the vertical rod 4, a punching device 6 is fixedly installed on the top of the top plate 5, a fixture body 9 is arranged on the top of the workbench 1, a socket 10 is opened on the outer side of the fixture body 9, and a mounting mechanism 3 is arranged on the top of the workbench 1, and the mounting mechanism 3 includes a mounting box 301;

[0029] A fixing mechanism 2 is provided on the top of the workbench 1, and the fixing mechanism 2 includes a box 201, which is fixedly installed on the top of the workbench 1, and a motor 202 is fixedly installed on the bottom of the workbench 1. The output end of the motor 202 is fixedly connected to a driving gear 203, and the bottom of the inner cavity of the box 201 is movably connected to a driven gear 204, and the right side of the driven gear 204 is meshed with the left side of the driving gear 203. A circular plate 205 is fixedly installed at the middle end of the inner cavity of the box 201, and the top of the driven gear 204 is fixedly connected to a punching device 6 through a rotating shaft, and a sliding groove 207 is opened on the top of the turntable 206, and a sliding rod 208 is movably connected in the inner cavity of the sliding groove 207, and a mounting block 209 is fixedly installed on the outer side of the sliding rod 208, and a connecting rod 210 is fixedly installed on the outer side of the mounting block 209.

[0030] By setting up the fixing mechanism 2, special-shaped parts of different sizes can be clamped and fixed, so as to avoid the situation that the special-shaped parts are easy to fall off from the inside of the clamp during the hole opening process due to the change of the size of the special-shaped parts and the lack of spacing adjustment of the clamp itself. By setting up the installation mechanism 3, the clamp can be disassembled and installed separately, so that the clamp matching the shape of the special-shaped parts can be installed conveniently, thereby improving the stability of the special-shaped parts when opening the hole, preventing the special-shaped parts from changing their position during the hole opening, thereby affecting the normal hole opening work. Example

[0031] In one embodiment, a movable groove 211 is provided at the middle end of the top of the circular plate 205, and a movable block 212 is fixedly installed at the bottom of the turntable 206. The bottom of the movable block 212 is movably connected to the inner cavity of the movable groove 211. Displacement grooves 213 are provided around the top of the circular plate 205, and the bottom of the mounting block 209 is slidably connected to the inner cavity of the displacement groove 213. The installation box 301 is fixedly installed on the inner side of the connecting rod 210, and a slot 302 is provided at the middle end of the front side of the installation box 301. The upper and lower sides of the inner surface of the installation box 301 are provided with a first cavity 303, and the top of the inner surface of the installation box 301 is provided with a second cavity 304. A driving shaft 305 is movably connected to the right side of the bottom of the second cavity 304, and a driven shaft 306 is movably connected to the left side of the bottom of the second cavity 304. A transmission belt 307 is movably connected between the driving shaft 305 and the driven shaft 306. A two-way threaded rod 308 is fixedly installed at the bottom of the driving shaft 305 and the driven shaft 306. The upper and lower sides of the outer surface of the two-way threaded rod 308 are threadedly connected to thread blocks 309, and a plug-in block 310 is fixedly installed on the inner side of the thread block 309. The outer side of the clamp body 9 is inserted into the inner cavity of the slot 302, and the top of the driving shaft 305 is fixedly connected to a handle 313.

[0032] By setting the movable block 212 and the movable groove 211, the turntable 206 can be limited to avoid deviation during movement, resulting in the inability to drive the clamp to clamp and fix the special-shaped part inward. By setting the displacement groove 213, the moving direction of the mounting block 209 can be fixed to avoid changes in direction when moving inward and outward, thereby preventing the special-shaped part from being fixed. By setting the bidirectional threaded rod 308, the threaded block 309 and the plug-in block 310, the clamp can be fixed to avoid the special-shaped part from shaking during opening due to its own looseness when fixing the special-shaped part, thereby affecting the normal opening work. Example

[0033] In one embodiment, plug-in slots 311 are provided on both the upper and lower sides of the inner cavity of the slot 302, the plug-in block 310 passes through the inner cavity of the plug-in slot 311 and is plugged into the inner cavity of the socket 10, and limiting slots 312 are provided on both the left and right sides of the inner cavity of the first cavity 303, the outer side of the threaded block 309 is slidably connected to the inner cavity of the limiting slot 312, and a movable slot 7 is provided on the top of the box 201, and a movable block 8 is fixedly installed on the bottom of the clamp body 9 by screws, and the bottom of the movable block 8 is slidably connected to the inner cavity of the movable slot 7.

[0034] By setting the plug-in slot 311, the moving direction of the plug-in block 310 can be limited to avoid deviation during movement, which would make it impossible to fix the clamp and make it impossible for the clamp to fix the special-shaped part when a hole is opened in the special-shaped part. By setting the limiting slot 312, the moving direction of the threaded block 309 can be limited to avoid synchronous rotation of the two-way threaded rod 308, which would make it impossible to fix the clamp normally. By setting the moving block 8 and the moving slot 7, the moving direction of the clamp body 9 can be limited to ensure that it can tightly clamp the special-shaped part and avoid position changes when a hole is opened in the special-shaped part.

[0035] When the utility model is working: after selecting a clamp that matches its appearance according to the shape of the special-shaped part, the clamp body 9 is inserted into the inner cavity of the slot 302, and then the handle 313 is grasped and rotated. At this time, the active shaft 305 cooperates with the driven shaft 306 and the transmission belt 307, and the two-way threaded rod 308 drives the threaded block 309 to move inward. At this time, the plug-in block 310 moves inward synchronously and is inserted into the inner cavity of the socket 10. After completing the installation of the clamp body 9, the special-shaped part is placed on the top of the box 201, and through the output of the motor 202, the active gear 203 drives the driven gear 204 to rotate, and through the mutual cooperation with the turntable 206, the sliding rod 208 drives the mounting block 209 to move inward along the inner cavity of the sliding groove 207, and then the connecting rod 210 drives the mounting mechanism 3 and the clamp body 9 to move inward synchronously, so as to realize the fixing of the special-shaped part.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
