[0002] During the manufacturing process of PCB milling cutters, the cutters are inspected, such as their outer diameter. This is typically done using laser diameter inspection equipment. Current methods involve mounting a jig containing several PCB milling cutters onto an inspection platform using fasteners such as screws, and then using laser inspection equipment. However, this approach has the following problems: 1. The loading fixture is inconvenient to fix and disassemble, which is not conducive to inspection. There is a lack of a device for limiting and fixing the loading fixture installed on the operating platform. 2. The loading fixtures need to be kept stable during testing. There is also a need to fix multiple loading fixtures at one time because the products to be inspected need to be sorted and collected after inspection. Therefore, multiple loading fixtures need to be fixed at the same time for sorting. Utility Model Content

Detailed Implementation

[0016] The embodiments will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-11 As shown in the preferred embodiment 1, the loading fixture clamping device for PCB milling cutter inspection includes an operating platform 1 mounted on the inspection device. The operating platform 1 is a hollow box structure. Several clamping units are arranged side by side on the top of the operating platform 1. Each clamping unit includes a mounting plate 3 that is detachably fixed on the operating platform 1. A limit component 4 is detachably mounted on one side of the mounting plate 3, and a rotating component 5 is detachably mounted on the other side of the mounting plate 3. All rotating components 5 are connected to the same rotating shaft 6 to form a rotating fit. A clamping component 7 corresponding to each clamping unit is linked on the rotating shaft 6. After the loading fixture body 2 is placed on the mounting plate 3, it is clamped between the corresponding clamping component 7 and the limit component 4. A telescopic component 9 is provided inside the operating platform 1. One end of the telescopic component 9 is linked to the rotating shaft 6 through a connecting rod assembly 8, and the other end of the telescopic component 9 is hinged to the side of the operating platform 1 away from the rotating shaft 6.

[0018] The mounting plate 3 has several concealed screw holes 302, and the operating platform 1 has screw holes that correspond one-to-one with the concealed screw holes 302 on the mounting plate 3. When the concealed screw holes 302 correspond to the screw holes, they are fixed in place by concealed screws 301. The mounting plate 3 is fixed by the concealed threaded engagement, making the surface of the mounting plate 3 flat and not affecting the placement of the loading fixture body 2.

[0019] The limiting component 4 includes an L-shaped limiting block 401. One right-angled side of the limiting block 401 is threadedly fixed to one side of the mounting plate 3 by a limiting screw 402. The limiting screw 402 passes through the top of the right-angled side and is threadedly engaged with the mounting plate 3, thereby pressing the limiting block 401 to form a fixed position. The loading fixture body 2 has a hollow groove 202 on one side, and the other right-angled side of the limiting block 401 is embedded in the hollow groove 202 to form a limiting fit, which forms a limiting with the end of the loading fixture body 2 away from the pressed end, thereby limiting the position of the loading fixture body 2 when clamping and maintaining the stability of the clamping.

[0020] Preferably, the loading fixture body 2 has a multi-layer hollow structure, with the layers cooperating to form a hollow groove 202. The right-angled side of the limiting block 401 can be selected from any hollow groove 202 for limiting, and the length of the right-angled side of the limiting side is controlled so as not to affect the normal placement of the milling cutter.

[0021] The loading fixture body 2 has four supporting columns 201 at its bottom corners. The mounting plate 3 has sliding grooves 304 corresponding to the supporting columns 201. When the loading fixture body 2 is supported on the mounting plate 3, the supporting columns 201 are embedded in the corresponding sliding grooves 304 and slide in the direction of clamping. The sliding grooves 304 ensure the clamping direction and limit, and provide a certain buffer path. In use, the loading fixture body 2 is placed on the mounting plate 3 so that the supporting columns 201 are in the corresponding sliding grooves 304. When clamping, the clamping assembly 7 pushes the loading fixture body 2 to slide along the sliding grooves 304. When it slides to the bottom, the supporting columns 201 are exactly at the end of the sliding grooves 304 to form a limit, and the hollow groove 202 is exactly at the right angle side of the limiting block 401 to form a limit.

[0022] The mounting plate 3 extends from the side away from the limiting component 4 in a direction away from the operating platform 1 to form an extension. The rotating component 5 is symmetrically arranged on both sides of the bottom of the extension about the middle position of the mounting plate 3. This ensures stable installation of the rotating shaft.

[0023] Each of the rotating components 5 includes an L-shaped rotating block 501. One right-angled side of the rotating block 501 is threadedly fixed to the bottom of the corresponding mounting plate 3 by mounting screws 503. The other right-angled side of the rotating block 501 is provided with an opening 502. All openings 502 are of the same size and are coaxially arranged. The rotating shaft 6 passes through all openings 502 and forms a coaxial rotational engagement with all openings 502. This ensures stable rotation of the rotating shaft 6 and facilitates easy installation and disassembly.

[0024] Each clamping unit corresponds to two clamping components 7. The clamping components 7 are symmetrically arranged about the middle position of the mounting plate 3 of the corresponding clamping unit, and all clamping components 7 overlap along the axis of the rotating shaft 6 and rotate synchronously through the rotating shaft 6.

[0025] Each clamping assembly 7 includes a clamping block 701. One end of the clamping block 701 is detachably fixed to the rotating shaft 6 and rotates synchronously with the rotating shaft 6. The other end of the clamping block 701 contacts the loading fixture body 2 circumferentially during rotation and cooperates with the limiting assembly 4 to clamp and fix the loading fixture body 2.

[0026] The linkage assembly 8 includes a linkage block 801. One end of the linkage block 801 is detachably fixed to the rotating shaft 6 and rotates synchronously with the rotating shaft 6. The other end of the linkage block 801 is hinged to one end of the telescopic assembly 9.

[0027] The telescopic assembly 9 includes a telescopic cylinder 901. The output end of the telescopic cylinder 901 is hinged to the linkage block 801, and the fixed end of the telescopic cylinder 901 is hinged to the side of the operating platform 1 away from the rotating shaft 6 via a hinge 903. When the telescopic cylinder 901 adjusts its length, the overall angular adaptability changes, thereby causing the hinged linkage block 801 to adapt and avoid conflict during movement.

[0028] The output state of the telescopic component 9 can be set to either a clamped state or an open state. When the telescopic component 9 is in the clamping state, the telescopic component 9 drives the rotating shaft 6 to rotate around the rotating component 5 through the connecting rod component 8, so that the clamping component 7 of each clamping unit rotates synchronously, and clamps and fixes each loading fixture body 2 between the corresponding clamping component 7 and the limiting component 4. When the telescopic assembly 9 is in the open state, the telescopic assembly 9 drives the rotating shaft 6 to rotate around the rotating assembly 5 through the connecting rod assembly 8, so that the clamping assembly 7 of each clamping unit rotates synchronously, opening each clamping assembly 7 away from the loading fixture body 2, thereby contacting the clamping limit.

[0029] The entire system can be connected to the existing control system of the corresponding detection device, and the switching of states can be controlled by the control system and control switches.

[0030] As a preferred embodiment 2, one end of the clamping block 701 is provided with a first fastening hole 702, and a first opening 703 extending radially through the clamping block 701 is provided on one side of the first fastening hole 702. The first opening 703 is provided on both sides of the first screw hole 704. A first fastener 705 is provided on the outside of the clamping block 701 to form a threaded engagement with the first screw hole 704 on both sides. After the rotating shaft 6 passes through the first fastening hole 702, the first fastener 705 tightens the first opening 703, thereby reducing the first fastening hole 702 to clamp and fix the rotating shaft 6 to form synchronous rotation, ensuring the fixed installation of the clamping block 701, and also facilitating adjustment and disassembly. The other end of the clamping block 701 contacts the loading fixture body 2 in the circumferential direction and cooperates with the limiting component 4 to clamp and fix the loading fixture body 2, ensuring the clamping fixture is secure.

[0031] As a preferred embodiment 3, the end of the clamping block 701 that contacts the loading fixture body 2 is provided with a pressure pad 706 with a certain elasticity, which is used to increase the degree of clamping and at the same time play a buffering role to prevent the clamping block 701 from damaging the loading fixture body 2.

[0032] As a preferred embodiment 4, one end of the linkage block 801 is provided with a second fastening hole 802, and a second opening 803 extending radially through the linkage block 801 is provided on one side of the second fastening hole 802. The second opening 803 is provided on both sides of the second screw hole 804. A second fastener 805 is provided on the outside of the linkage block 801 to form a threaded engagement with the second screw hole 804 on both sides. After the rotating shaft 6 passes through the second fastening hole 802, the second fastener 805 tightens the second opening 803, thereby reducing the size of the second fastening hole 802 and clamping and fixing the rotating shaft 6 to form synchronous rotation. The other end of the linkage block 801 is provided with a hinge seat 806, and the output end of the telescopic cylinder 901 is provided with a hinge joint 902. The hinge joint 902 corresponds to the hinge seat 806, and the hinge joint 902 forms a hinged engagement with the hinge seat 806 through the hinge shaft 807.

[0033] As a preferred embodiment 5, the hinge shaft 807 can be a bolt screw. The clamping degree of the hinge seat 806 on the hinge joint 902 can be changed by the tightening fit of the nuts on both sides of the bolt. This can control the flexibility of the hinge to a certain extent, avoid the hinge changing too flexibly during the extension and retraction process, and ensure the stability of the process.

[0034] In a preferred embodiment 6, the first opening 703 and the second opening 803 are arranged in opposite directions, and the clamping block 701 and the linkage block 801 are arranged in opposite directions. In the clamping state, the clamping block 701 is in a vertical position and is arranged upwards. The first opening 703 of the clamping block 701 extends downwards. The top of the clamping block 701 presses the loading fixture body 2 body through the pressure pad 706. Meanwhile, the linkage block 801 is in a vertical position and is arranged downwards. The second opening 803 of the linkage block 801 extends upwards. The bottom of the linkage block 801 is hinged to the telescopic component 9. The telescopic component 9 is in an extended state. When in the open state, the clamping block 701 is in an inclined state away from the operating platform 1 and is arranged upwards. The first opening 703 of the clamping block 701 extends downwards in an inclined state. The top of the clamping block 701 opens away from the operating platform 1 and leaves the loading fixture body 2. Meanwhile, the linkage block 801 is in an inclined state close to the operating platform 1 and is arranged downwards. The second opening 803 of the linkage block 801 extends upwards in an inclined state. The bottom of the linkage block 801 is hinged to the telescopic assembly 9, and the telescopic assembly 9 is in the retracted state.

[0035] As a preferred embodiment 7, each mounting plate 3 has an arc-shaped opening 303 on the side away from the limiting component 4, and the clamping components 7 corresponding to the mounting plate 3 are all located within the arc-shaped opening 303, providing more rotation space and facilitating adjustment.

[0036] As a preferred embodiment 8, each clamping unit has four concealed screw holes 302, and the concealed screw holes 302 are symmetrical about the middle position of the mounting plate 3; Each clamping unit has four sliding grooves 304, two on one side; Each limit block 401 is fixed by two limit screws 402; Each rotating block 501 is secured by two mounting screws 503.

[0037] In a preferred embodiment 9, the first fastener 705 can be a screw; The second fastener 805 can be a screw.

[0038] The working principle of this utility model: The output state of the telescopic component 9 can be set to either a clamped state or an open state. When the telescopic component 9 is in the clamping state, the telescopic component 9 drives the rotating shaft 6 to rotate around the rotating component 5 through the connecting rod component 8, so that the clamping component 7 of each clamping unit rotates synchronously, and clamps and fixes each loading fixture body 2 between the corresponding clamping component 7 and the limiting component 4. When the telescopic assembly 9 is in the open state, the telescopic assembly 9 drives the rotating shaft 6 to rotate around the rotating assembly 5 through the connecting rod assembly 8, so that the clamping assembly 7 of each clamping unit rotates synchronously, opening each clamping assembly 7 away from the loading fixture body 2, thereby contacting the clamping limit.
