[0049] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0050] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0051] Please see Figure 1 and Figure 2 This embodiment provides a clamping fixture that can be used for clamping and fixing products during internal cavity machining and external machining.

[0052] The clamping fixture provided in this embodiment includes a first clamping module 100 and a second clamping module 200. The first clamping module 100 includes a lifting component 120 and a first clamping component 130. The lifting component 120 is provided with a hollowed-out clearance opening 1220, which facilitates the loading and unloading of products and the entry and exit of cutting tools for processing.

[0053] Furthermore, the lifting assembly 120 is provided with a plurality of first clamping assemblies 130, which are arranged around the clearance opening 1220 to clamp and fix the product around its perimeter.

[0054] The second clamping module 200 includes a positioning plate 210 and a second clamping assembly 220. The positioning plate 210 is disposed in the clearance opening 1220, and the second clamping assembly 220 is disposed on the positioning plate 210. The positioning plate 210 is used to position the product to be processed, and the second clamping assembly 220 can clamp the product from the inner cavity of the product.

[0055] In some embodiments, the positioning plate 210 is provided with adsorption holes and connected to an external negative pressure device to perform preliminary positioning of the product by vacuum adsorption.

[0056] Therefore, it can be understood that the clamping jig provided by the embodiment can position the product on the positioning plate 210 during product processing, and the product is exposed in the avoiding opening 1220 at this time. When the inner cavity of the product needs to be processed (such as milling, drilling, or polishing), the plurality of first clamping assemblies 130 are first driven to rise by the lifting assembly 120 to clamp the periphery of the product by a preset stroke, and the second clamping assembly 220 does not participate in clamping, so that the machining tool can be inserted into the inner cavity of the product for machining, and the machining tool is prevented from interfering with the second clamping assembly 220. When the periphery of the product needs to be processed (such as milling, drilling, or polishing), the first clamping assembly 130 is released from clamping the product, and the plurality of first clamping assemblies 130 are driven to descend by the lifting assembly 120 by a preset stroke, so that the periphery of the product is exposed and is not blocked. At this time, the product can be fixed on the positioning plate 210 by the second clamping assembly 220, and the periphery of the product can be machined. In this way, the machining of the inner cavity and the periphery of the product is switched, and the product remains on the positioning plate 210 and needs to be positioned only once. On the one hand, the product does not need to be transported multiple times, reducing the labor intensity, reducing the risk of product damage, reducing the yield loss caused by external factors, and reducing the use of resources for repeated processes. On the other hand, the product positioning tolerance is accumulated by twice clamping and once positioning, thereby improving the machining precision and improving the production yield.

[0057] In order to more clearly describe the technical solutions of the present application, the clamping jig provided by the embodiment is described below as follows.

[0058] Please refer to Figure 3 and Figure 4 The lifting assembly 120 includes a lifting driving mechanism 121 and a lifting plate 122. The first clamping module 100 further includes a base 110, and the lifting driving mechanism 121 is arranged on the base 110, that is, the base 110 can provide support for the lifting driving mechanism 121. The lifting plate 122 is arranged above the base 110 and is connected to the driving end of the lifting driving mechanism 121.

[0059] In the embodiment, the middle part of the lifting plate 122 is provided with the avoiding opening 1220, and the first clamping assembly 130 is arranged on the lifting plate 122.

[0060] The lifting driving mechanism 121 can be provided in multiple numbers, and the plurality of lifting driving mechanisms 121 can be distributed at the four corners of the base plate, thereby providing stable support for the lifting plate 122 and ensuring that the lifting plate 122 can stably rise and fall in a direction perpendicular to the base plate.

[0061] Further, the side of the lifting plate 122 corresponding to the lifting driving mechanism 121 is provided with a connecting seat 123. The driving end of the lifting driving mechanism 121 is provided with a connecting rod 124, which is clamped in the clamping groove 1230 of the connecting seat 123 and is in clearance fit with the clamping groove 1230. In this way, the connecting rod 124 is clamped in the clamping groove 1230, which limits the connecting rod 124 from coming out of the clamping groove 1230 and limits the axial direction of the connecting rod 124. It can also be understood that the connecting rod 124 and the connecting seat 123 are in clearance fit, which prevents the lifting driving mechanism 121 from being tilted and stuck due to different steps.

[0062] In some embodiments, the top of the connecting rod 124 is spherical, which contacts at a point when rising, preventing large-area contact from causing the lifting mechanism to tilt and vibrate, thereby accelerating the wear of parts.

[0063] In some embodiments, referring to Figure 10 , the connecting rod 124 includes a head and a rod portion, and the rod portion is in threaded fit with the lifting shaft of the lifting driving mechanism 121. The connecting seat 123 is provided with two clamping grooves 1230, the head of the connecting rod 124 is in fit with the upper clamping groove 1230, the upper clamping groove 1230 limits the rotation of the connecting rod 124, and the lifting shaft of the lifting driving mechanism 121 is in fit with the lower clamping groove 1230, the lower clamping groove 1230 limits the rotation of the cylinder, preventing the connecting rod 124 from being pulled off due to intermittent force during the force process, thereby causing the movement mechanism to fail.

[0064] Optionally, the lifting driving mechanism 121 can be an oil cylinder, a gas cylinder, an electric cylinder or a lead screw motor. It should be understood that the above is only an example and does not limit the protection scope of the present application.

[0065] In the present embodiment, the side of the lifting plate 122 facing the base 110 is also provided with a plurality of limiting blocks 126 (as shown in Figure 4 , the limiting end of the limiting block 126 extends to the inner side of the avoiding opening 1220 and to the middle of the avoiding opening 1220. In this way, when the lifting plate 122 rises to a preset position (which is the position at which the first clamping assembly 130 can clamp the product), the limiting block 126 will rise by a preset stroke, and at this time, the limiting end of the limiting block 126 will abut against the positioning plate 210, thereby limiting the lifting plate 122 from continuing to rise, thereby achieving the height limiting of the lifting plate 122.

[0066] Please refer to Figure 4 and Figure 5, the first clamping assembly 130 comprises a rotating clamp 131 and a first rotating driving mechanism 132; the rotating clamp 131 is arranged above the lifting assembly 120, and the rotating clamp 131 comprises a rotatable switching compression state and a decompression state. The first rotating driving mechanism 132 is arranged on the lifting assembly 120 and is drivingly connected with the rotating clamp 131. In this way, the rotating clamp 131 can be driven by the first rotating driving mechanism 132 to rotate and switch between the compression state and the decompression state. It can be understood that, in the compression state, the rotating clamp 131 compresses the periphery of the product to prevent the product from moving during processing; in the decompression state, the rotating clamp 131 deviates from the product, that is, does not contact the product. Further, when the rotating clamp 131 compresses the periphery of the product, it can compress the skirt of the periphery of the product, which will be removed as waste in subsequent processing, avoiding direct compression of the product affecting the quality of the product.

[0067] In some embodiments, the switching angle of the compression state and the decompression state of the rotating clamp 131 is 90° or 180°. It should be understood that the above is only an example and is not a limitation of the protection scope of the present application.

[0068] Further, the rotating clamp 131 comprises a pressing part 1310, a connecting part 1311 and a limiting guide part 1312. The connecting part 1311 is drivingly connected with the output end of the first rotating driving mechanism 132, the pressing part 1310 and the limiting guide part 1312 are respectively formed at two ends of the connecting part 1311 along the radial direction of the rotating axis of the connecting part 1311, and the limiting guide part 1312 is provided with a limiting guide notch 1313. The lifting plate 122 of the lifting assembly 120 is provided with a guide column 125. When the rotating clamp 131 rotates to the compression state, the guide column 125 can be clamped in the limiting guide notch 1313. The provision of the guide column 125 can give a certain guiding effect when the rotating clamp 131 is pressed down, mainly to prevent the rotating clamp 131 from shaking too much and damaging the tool.

[0069] Please refer to Figure 2 In the present embodiment, the first clamping module 100 further comprises a guide assembly 140, which can guide the lifting of the lifting plate 122 to ensure that the lifting of the lifting plate 122 is more stable. The number of guide assemblies 140 can be set to multiple, and the multiple guide assemblies 140 can be arranged close to the two sides or two ends of the lifting plate 122.

[0070] In order to describe more clearly, the guide assembly 140 is described below. Specifically, the guide assembly 140 comprises a guide seat 141 and a guide shaft 142. The guide seat 141 is arranged on the base 110; one end of the guide shaft 142 is arranged on the lifting assembly 120, and the other end penetrates through the guide hole of the guide seat 141 and is in clearance fit with the guide hole. In this way, the guide shaft 142 is an optical axis and can slide in the guide seat 141 along the axial direction.

[0071] Optionally, a linear bearing is built in the guide seat 141 to further reduce the friction during the sliding of the guide shaft 142.

[0072] Please refer to Figure 1 and Figure 3 The second clamping assembly 220 includes a positioning cover plate 221, a second rotary driving mechanism 222, and a spinning pull rod 223. The positioning cover plate 221 is arranged above the positioning plate 210 and forms a clamping space with the positioning plate 210; the clamping space can accommodate products to be clamped by the positioning cover plate 221 and the positioning plate 210.

[0073] The second rotary driving mechanism 222 is arranged on the positioning plate 210. The spinning pull rod 223 is connected with the second rotary driving mechanism 222, and the positioning cover plate 221 is provided with a long hole through which the spinning pull rod 223 passes.

[0074] The spinning pull rod 223 includes a decompression state and a compression state which can be switched, and the second rotary driving mechanism 222 can drive the spinning pull rod 223 to switch between the decompression state and the compression state. In the decompression state, the compression end of the spinning pull rod 223 is aligned with the long hole on the positioning cover plate 221, so as to facilitate the disassembly of the positioning cover plate 221; after switching to the compression state, the compression end of the spinning pull rod 223 is rotated and then pulled down and abuts against the side of the positioning cover plate 221 away from the positioning plate 210.

[0075] Optionally, the switching angle of the compression state and the decompression state of the spinning pull rod 223 is 90° or 180°, and of course it can also be other angles. It should be understood that the above is only an example and does not limit the protection scope of the present application.

[0076] Further, the base 110 is provided with a support block 111, and the positioning plate 210 is arranged on the support block 111 and forms a receiving space with the base 110. The second rotary driving mechanism 222 is received in the receiving space.

[0077] Optionally, the second rotary driving mechanism 222 is a pneumatic cylinder, preferably a zero-degree rotary pneumatic cylinder. The spinning pull rod 223 is assembled on the zero-degree rotary pneumatic cylinder shaft through a round pin, can swing slightly left and right, and tightens the positioning cover plate 221. In this way, the spinning pull rod 223 also serves as a positioning auxiliary part for initially installing the product on the positioning plate 210.

[0078] Please refer to Figures 1 to 6 The present application also provides a machining device. As shown in Figure 6 The machining device includes the clamping jig provided according to the above embodiments. The clamping jig is installed on a multi-degree-of-freedom workbench 1000 (for example, a workbench with 4.5 axes) of the machining device.

[0079] Please see Figure 7 , Figure 8 and Figure 9 , in order to more clearly describe the technical solutions of the present application, the working process of the clamping fixture applied in the machining equipment is described below by taking the machining of a mobile phone frame as an example:

[0080] (1) Product inner cavity machining (as shown in Figure 7 ): The four-around lifting driving mechanism 121 drives the lifting plate 122 to descend (the rotary pressing jaw 131 is switched to the decompression state) → the product to be machined is placed on the positioning plate 210 for positioning → the four-around lifting driving mechanism 121 drives the lifting plate 122 to ascend to a preset position → the first rotary driving mechanism 132 drives the rotary pressing jaw 131 to rotate to the compression state to compress the product → the inner cavity of the product is machined;

[0081] (2) Product outer periphery machining (as shown in Figure 8 ): After the inner cavity machining is completed, the product is placed on the positioning cover plate 221 after blowing away the chips → the second rotary driving mechanism 222 drives the rotary pressing pull rod 223 to compress the positioning cover plate 221 → the first rotary driving mechanism 132 drives the rotary pressing jaw 131 to rotate to the decompression state to open → the four-around lifting driving mechanism 121 drives the lifting plate 122 to descend → the outer periphery machining is started;

[0082] (3) Machining conversion (as shown in Figure 9 ): After the outer periphery machining is completed, the machining spindle is replaced with a rough polishing tool handle → the product is rough polished around until the surface tool marks and defects are removed → the machining spindle is replaced with a milling cutter → the four-around side hole machining is performed → the machining spindle is replaced with a medium polishing tool handle → the product is medium polished around until the surface is reflective → the second rotary driving mechanism 222 drives the rotary pressing pull rod 223 to switch to the decompression state to open → the positioning cover plate 221 is removed → the product is taken out → the program ends and the machining is completed.

[0083] It can be understood that the clamping fixture provided in the embodiment can be reused by only replacing the lifting plate 122 and the positioning cover plate 221 according to different products, thereby saving the cost of the fixture.
