[0032] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0033] Please see Figures 1 to 7 The present invention provides a push-pull type feeding fixture for CNC, comprising a base 1, an upper fixed plate 2, a lifting plate 3, a fixture 4, and a driving component 5.

[0034] The lifting plate 3 is located between the upper fixed plate 2 and the base 1, and the driving component 5 is located on the base 1 and drives the lifting plate 3 to move towards or away from the upper fixed plate 2.

[0035] The fixture 4 includes a pressure plate 41 and a carrier plate 42. The pressure plate 41 is disposed on the upper fixed plate 2, and the carrier plate 42 is slidably connected to the lifting plate 3. The movement direction of the carrier plate 42 is intersected with the movement direction of the lifting plate 3.

[0036] The upper fixing plate 2 is provided with a through hole 21, which penetrates the upper fixing plate 2 along the thickness direction.

[0037] Specifically, in this embodiment, when the external workpiece 100 needs to be placed into the CNC equipment for processing, the drive component 5 first drives the lifting plate 3 to move downward. Simultaneously, the carrier plate 42 of the fixture 4 moves downward, and the carrier plate 42 disengages from the pressure plate 41. Then, the carrier plate 42 is pulled out, the external workpiece 100 is placed into the carrier plate 42, and then the carrier plate 42 is pushed back to its original position. The drive component 5 drives the lifting plate 3 to move upward, and the carrier plate 42 and the pressure plate 41 close together. The external processing head passes through the through hole 21 to process the external workpiece 100. After processing is completed, the drive component 5 drives the lifting plate 3 and the carrier plate 42 to move downward, the carrier plate 42 disengages from the pressure plate 41, the carrier plate 42 is pulled out, the processed workpiece 100 is removed, and the workpiece 100 to be processed is placed on the carrier plate 42. The above actions are repeated to complete the workpiece loading, processing, and unloading.

[0038] By setting up a base 1, an upper fixed plate 2, a lifting plate 3, a fixture 4, and a driving component 5, the fixture 4 includes a pressure plate 41 and a carrying plate 42. The carrying plate 42 is slidably connected to the lifting plate 3. The driving component 5 drives the lifting plate 3 to rise and fall, and the carrying plate 42 slides horizontally on the lifting plate 3, thereby achieving the purpose of rapid loading and unloading in the CNC machining center and improving production efficiency.

[0039] The number of perforations 21 is two, and the pressure plate 41 is located between the two perforations 21. The two perforations 21 are processed as needed, so that the external processing head can process two parts of the workpiece 100 at the same time, thereby improving production efficiency.

[0040] The push-pull type loading fixture for CNC also includes a guide post 6. The two ends of the guide post 6 are respectively connected to the base 1 and the upper fixed plate 2. The lifting plate 3 is slidably connected to the guide post 6. The guide post 6 ensures the stability of the installation structure of the base 1 and the upper fixed plate 2, and at the same time ensures the stability of the lifting process of the lifting plate 3, and ensures the controllability of the processing quality.

[0041] The carrier plate 42 includes a base plate 421, a hole positioning member 422, and a mold closing positioning block 423. The hole positioning member 422 is disposed on the base plate 421 and protrudes from the base plate 421. The mold closing positioning block 423 is disposed on the base plate 421 and protrudes from the base plate 421. The height of the mold closing positioning block 423 protruding from the base plate 421 is greater than the height of the hole positioning member 422 protruding from the base plate 421. Preferably, there are three hole positioning members 422. The external workpiece 100 is accurately placed on the carrier plate 42 through the hole positioning members 422. The upper positioning hole 411 is processed on the pressure plate 41. The upper positioning hole 411 is elongated. The mold closing positioning block 423 is also elongated. When the carrier plate 42 moves upward and approaches the pressure plate 41, the mold closing positioning block 423 first extends into the upper positioning hole 411, which plays a role in pre-positioning the pressure plate 41 and the carrier plate 42, ensuring accurate mold closing and improving the processing qualification rate.

[0042] The carrier plate 42 also includes a product fixing part 424, which protrudes from the upper surface of the substrate 421. The height of the product fixing part 424 protruding from the substrate 421 is less than the height of the hole positioning part 422 protruding from the substrate 421. The outer contour of the product fixing part 424 matches the external workpiece 100, thus pre-fixing the workpiece 100.

[0043] The hole positioning component 422 includes a mounting sleeve 4221 and a tapered portion 4222. The mounting sleeve 4221 is disposed on the substrate 421 or the product fixing portion 422. The tapered portion 4222 is disposed on the mounting sleeve 4221 and protrudes from the mounting sleeve 4221. The mounting sleeve 4221 is fixed to the substrate 421 and the product fixing portion 422. The tapered portion 4222 is fixed inside the mounting sleeve 4221. The tapered portion 4222 is provided to facilitate fine adjustment of the external workpiece 100. That is, the hole of the external workpiece 100 can be slightly adjusted relative to the tapered portion 4222 to achieve the purpose of static positioning.

[0044] The push-pull type loading fixture for CNC also includes a guide assembly 7, which includes a guide rail 71 and a slider 72. The guide rail 71 is located on the lifting plate 3, and the slider 72 is located on the material carrier plate 42. The slider 72 is slidably connected to the guide rail 71. The arrangement of the guide rail 71 and the slider 72 makes the material carrier plate 42 move more smoothly in the horizontal movement process and ensures the stability of the movement direction.

[0045] The guide assembly 7 also includes a baffle 73, which is disposed on the lifting plate 3 and located at both ends of the guide rail 71 along its length. The baffle 73 limits the horizontal movement of the material carrier plate 42, thereby improving production safety.

[0046] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
