The device for facilitating the installation of ceramic fixtures for powder metallurgy products, employing the above structure, uses a fixture pushing component to push a push rod into the through hole of the powder metallurgy product.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, when the aforementioned equipment is used, the product itself has several positioning holes, and the support fixture has several corresponding positioning pins. When the product is placed on the support fixture, the positioning holes and positioning pins must be matched one by one, which is inefficient. Moreover, when the workload is large and the device operates at a high speed, errors will inevitably occur during the process of aligning the positioning holes and positioning pins of the product when it is placed on the support fixture, which will slow down the product processing process and affect the product preparation efficiency.

[0005] Therefore, it is urgent to improve the automatic machining and assembly equipment for rotating shafts in order to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic processing and assembly device for rotating shafts. By enlarging the placement slots on the placement block for placing products, the device facilitates product placement and improves worker placement efficiency. Then, a pushing component and a straightening component are used to correct and limit the final position of the product. Finally, a power component drives the positioning column to stabilize the product. In this process, the efficiency is improved compared to existing technology structures, whether placing or picking up the product. It eliminates the need to deliberately engage the positioning hole with the positioning column, saving the trouble of manual calibration, greatly increasing the product preparation efficiency and accelerating the product preparation process.

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figure 1 - Figure 7 As shown in the background section, the prior art includes a jig pushing component, a jig ejection component, and related structural components for pushing ceramic jigs. These structures are used in conjunction with the related structures in this utility model. Since they are prior art features, they will not be described in detail here. Please refer to the prior art for details.

[0027] The automatic processing and assembly device for rotating shafts provided in this embodiment includes an operating table 1 and a frustum 2 rotating on the operating table 1, and a controller 19. The rotation of the frustum 2 is driven by a drive device on the device. At least two placement blocks 3 are equidistantly arranged around the central axis on the frustum 2. In the device structure of this utility model, four placement blocks 3 are provided, and four workstations are provided corresponding to the four placement blocks 3, namely the first workstation 24, the second workstation 25, the third workstation 26, and the fourth workstation 27. Placement slots 4 for placing products are opened on the placement blocks 3. In the existing technical structure, both sides of the placement slot 4 are equipped with correction components for aligning the product. The two correction components start and operate synchronously. One end of the placement slot 4 is equipped with a pushing component for moving the product. A positioning post 5 is slidably connected to the bottom wall of the placement slot 4. One end of the positioning post 5 penetrates the bottom wall of the placement slot 4 and extends into the positioning hole 6 opened on the product. The positioning post 5 is movably connected to the positioning hole 6 on the product. The placement block 3 is equipped with a power component for driving the positioning post 5 to slide. When the product is placed in the placement slot 4, it can be placed arbitrarily, as long as the product is not inverted. The product is positioned at both ends. Then, the correction component is used to push and calibrate the product from both sides, gradually aligning the product's side with the side wall of the placement slot 4 and positioning the product at the center line of the placement slot 4. During this process, the pushing component pushes one end of the product to the appropriate position. Through the cooperation between the pushing component and the correction component, the product is restricted to the appropriate position. At this point, the positioning hole 6 on the product corresponds to the position of the positioning post 5 on the placement block 3. Next, the power component drives the positioning post 5 to slide upward until one end of the positioning post 5 is inserted into the positioning hole 6. At this point, the product is restricted and the next operation can be performed. The pushing component and the correction component return to their initial positions. For specific operating procedures and equipment operation, please refer to the structural operation in the comparative document. Detailed descriptions are not provided here. During the product restriction process, the product can be placed freely without deliberately engaging the positioning hole 6 and the positioning post 5, eliminating the trouble of manual calibration, greatly increasing product preparation efficiency, and reducing the workload of workers. When the product is collected, it can be picked up directly, which is convenient and quick.

[0028] The correction component includes a correction plate 7 and a telescopic rod 8 set on the frustum 2. Sliding grooves 9 are provided on the side walls of the placement slot 4. The correction plate 7 is slidably connected to the sliding groove 9. The movable end of the telescopic rod 8 extends into the sliding groove 9 and is connected to the correction plate 7. The movable end of the telescopic rod 8 drives the correction plate 7 to slide in the sliding groove 9, thereby pushing and limiting the side position of the product.

[0029] Furthermore, the pushing component includes a pushing plate 10 and a telescopic rod 11 disposed on the frustum 2. A sliding groove 12 is provided at one end of the placement slot 4. The pushing plate 10 is slidably connected to the sliding groove 12. The movable end of the telescopic rod 11 is connected to the pushing plate 10. The movable end of the telescopic rod 11 drives the pushing plate 10 to slide in the sliding groove 12, thereby pushing and limiting the positions of both ends of the product. In order to cooperate with the use of the pushing component, a blocking protrusion 23 is provided at the end of the placement slot 4 away from the pushing plate 10, which plays a role in blocking and limiting the product.

[0030] Furthermore, the placement block 3 is equipped with a sliding chamber 13, and a lifting plate 14 is slidably connected inside the sliding chamber 13. The positioning column 5 is connected to the upper surface of the lifting plate 14. The power assembly includes a sliding tube 15 connected to the bottom wall of the sliding chamber 13, a top column 16 slidably connected to the sliding tube 15, an air pump 17 set on the frustum 2, and an air guide pipe 18 connecting the inside of the sliding tube 15 to the output end of the air pump 17. The end of the top column 16 away from the sliding tube 15 is connected to the lifting plate 14. In use, the air pump 17 is started, and the air pump 17 guides air into the sliding tube 15 through the air guide pipe 18, thereby increasing the internal air pressure. Then, it pushes the top column 16 to move upward, thereby driving the lifting plate 14 to move, and finally driving the positioning column 5 to move upward. When the positioning column 5 needs to move downward, it is only necessary to reduce the air pressure inside the sliding tube 15, which can be done by the air pump 17. The air pump 17 is an existing technology device and will not be described in detail.

[0031] Furthermore, telescopic rod 8, telescopic rod 11, and air pump 17 are electrically connected to the output of controller 19. A touch sensor 20 is installed on the bottom wall of the placement slot 4. After the touch sensor 20 senses the product, it generates a touch signal and transmits the touch signal to the input of controller 19. Controller 19 outputs a control signal, which controls the operation of telescopic rod 8, telescopic rod 11, and air pump 17. When the product is placed in the placement slot 4, the touch sensor 20 can sense the product. After the controller 19 receives the sensing signal transmitted by the touch sensor 20, it controls the telescopic rod 8, telescopic rod 11, and air pump 17 to operate, thereby limiting the position of the product and finally securing the product in the placement slot 4. After the product is removed, the controller 19 no longer receives the touch signal and will cause the power component to move the positioning column 5 down and return it to its initial position, ready for the next use.

[0032] Furthermore, in the existing technical equipment structure, there is a telescopic rod 28 and a pressure block 29. The shape of one end of the pressure block 29 has been adjusted to suit the structure of this utility model, but its function remains unchanged. When the ceramic fixture is ejected by the fixture ejection component, it falls into the receiving box 22. Due to the influence of the structure in this utility model, the position of the receiving box 22 has been adjusted. Specifically, a guide channel 21 is connected to the end of the placement slot 4 near the push plate 10. The output end of the guide channel 21 is provided with the receiving box 22, and the receiving box 22 is set on the frustum 2. After the ceramic fixture is ejected, it will slide into the receiving box 22 along the guide channel 21.
