Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and more specifically, to a universal telescopic processing positioning device and processing equipment. Background Technology

[0002] In the field of machining, positioning and clamping are crucial steps in ensuring machining accuracy and quality. While traditional side-push clamping methods are simple and effective, they have certain limitations in practical applications, especially in machining applications requiring high precision and high quality.

[0003] Side-clamping typically applies force parallel to the workpiece's sidewall to secure it. However, this clamping method is prone to friction with the workpiece's sidewall during extension and retraction, leading to scratches on the workpiece surface. Scratches not only affect the workpiece's appearance but may also weaken its structural strength and reduce its service life. Therefore, the presence of scratches increases the scrap rate and raises production costs. Utility Model Content

[0004] In view of this, the present invention provides a universal telescopic machining positioning device and machining equipment, which aims to solve the above-mentioned technical problems.

[0005] On one hand, the present invention proposes a universal telescopic processing positioning device, including a rotary table and a telescopic fixture disposed on the rotary table. The product to be processed is placed on the support component of the telescopic fixture, and the telescopic fixture positions the product to be processed by a plurality of height clamping components, a plurality of side-push telescopic components and a vacuum adsorption component. At least a portion of the side-push telescopic component is inclinedly disposed on the support component. The side-push telescopic component has a lateral pressing part that abuts against the side wall of the product to be processed. At least a portion of the side-push telescopic component tilts and drives the lateral pressing part to approach the side wall of the product to be processed.

[0006] In some embodiments of this application, the side-push telescopic assembly includes a telescopic driver 1 that is movably connected to the support assembly and is distributed at an acute angle to the sidewall of the product to be processed, and the telescopic rod of the telescopic driver 1 is connected to the lateral pressing part.

[0007] In some embodiments of this application, the support assembly is provided with an inclined hole, the telescopic rod of the telescopic driver is connected to a sliding part that slides with the inclined hole, the sliding part is provided with the lateral pressing part exposed in the inclined hole, and the telescopic driver is fixed to the support assembly by a flange.

[0008] In some embodiments of this application, the lateral clamping portion has a mating plane that matches and abuts against the sidewall of the product to be processed.

[0009] In some embodiments of this application, the lateral clamping portion has an arcuate convex surface that tangentially abuts against the sidewall of the product to be processed.

[0010] In some embodiments of this application, a material discharge hole is provided between the side-push telescopic component and the product to be processed.

[0011] In some embodiments of this application, the height clamping assembly includes a corresponding pressure claw and a height limiting block. At least a portion of the pressure claw is rotatably mounted on a rotating shaft on the outside of the support assembly. A telescopic driver second mounted on the support assembly is connected to one end of the pressure claw and drives the pressure claw to rotate around the rotating shaft and approach the height limiting block. The height limiting block is mounted on the top surface of the side wall of the support assembly.

[0012] In some embodiments of this application, the height limiting block includes a fixing block disposed on the top surface of the side wall of the supporting component and a limiting block at least partially disposed on the fixing block, and the remaining portion of the limiting block abuts against the top surface of the side wall of the product to be processed.

[0013] In some embodiments of this application, the vacuum adsorption assembly includes a gas storage tank and a vacuum suction pipe. The gas storage tank is disposed between the support assembly and the rotary table. One end of the vacuum suction pipe is connected to the internal gas storage space of the gas storage tank. The support assembly is provided with a plurality of suction holes that communicate with the internal gas storage space of the gas storage tank.

[0014] Compared with existing technologies, the advantages of this invention are that the rotary table enables multi-angle machining, and the adjustability of the telescopic fixture adapts to different workpieces. The height clamping assembly and the side-push telescopic assembly work together to fix the workpiece from the top, bottom, and sides, while the vacuum adsorption assembly provides additional fixing force to ensure the stability of the workpiece during machining. Furthermore, by tilting at least a portion of the side-push telescopic assembly onto the support assembly, this invention creates an angle between the side-push telescopic assembly and the side wall of the product to be processed. When clamping the product, it only contacts the side wall of the product through the lateral pressing part, avoiding the product scratches caused by side-push telescopic movements parallel to the side wall of the product.

[0015] On the other hand, the universal telescopic processing equipment proposed in this utility model includes the aforementioned universal telescopic processing positioning device.

[0016] It is understood that the universal telescopic processing equipment in this embodiment has the same beneficial effects as the universal telescopic processing positioning device described above, and will not be repeated here. Attached Figure Description

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Therefore, they should not be construed as limitations on this application.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] On one hand, combining Figure 1 and Figure 2 As shown, this embodiment provides a universal telescopic processing positioning device, including a rotary table 1 and a telescopic fixture 2 disposed on the rotary table 1. The product to be processed 3 is placed on the support component of the telescopic fixture 2, and the telescopic fixture 2 positions the product to be processed 3 through several height clamping components, several side push telescopic components and vacuum adsorption components. At least a portion of the side push telescopic component is inclinedly disposed on the support component. The side push telescopic component has a lateral pressing part 233 that abuts against the side wall of the product to be processed 3. At least a portion of the side push telescopic component tilts and drives the lateral pressing part 233 to approach the side wall of the product to be processed 3.

[0029] Understandably, in this embodiment, the rotary table 1 is used to support and rotate the product 3 to be processed, enabling it to be processed at multiple angles, thus improving processing flexibility and efficiency. The telescopic fixture 2 is adjustable to accommodate different workpieces. The telescopic fixture 2 is mounted on the rotary table 1 and is adjustable, capable of accommodating workpieces of different sizes and shapes. The telescopic fixture 2 includes a support assembly for supporting the product 3 to be processed, a height clamping assembly to ensure the stability of the workpiece in the vertical direction, a side-push telescopic assembly tilted on the support assembly, and a lateral pressing part 233 for fixing the workpiece from the side, while the vacuum adsorption assembly provides additional fixing force by generating negative pressure to adsorb the workpiece from below, ensuring the stability of the workpiece during processing. Furthermore, in this embodiment, the tilted arrangement of the side-push telescopic assembly effectively avoids surface scratches caused by movement parallel to the sidewall of the product 3 to be processed, improving workpiece quality and processing efficiency.

[0030] Combination Figure 5As shown, in one specific embodiment of this application, the side-push telescopic assembly includes a telescopic driver 23 that is movably connected to the support assembly and is distributed at an acute angle to the side wall of the product to be processed 3. A lateral pressing part 233 is connected to the telescopic rod of the telescopic driver 23.

[0031] Specifically, in this embodiment, several side-pushing telescopic components are located on three side walls of the workpiece to be processed and clamped therebetween, specifically one long side wall and two short side walls.

[0032] It is understood that the acute angle distribution design between the telescopic actuator 23 and the side wall of the product 3 to be processed in this embodiment ensures that the telescopic actuator 23 will not directly contact the side wall of the product 3 to be processed during the driving process. It only generates a lateral clamping force on the product 3 to be processed through the lateral clamping part when clamping. This not only improves the accuracy and stability of clamping, but also effectively avoids the surface damage problem that may be caused by traditional fixtures. It is suitable for precision machining occasions with high surface quality requirements.

[0033] Combination Figure 2 and Figure 4 As shown, in a specific embodiment of this application, the support component is provided with an inclined hole 221, and the telescopic rod of the telescopic driver 23 is connected with a sliding part 232 that slides with the inclined hole 221. The sliding part 232 is provided with a lateral pressing part 233 exposed in the inclined hole 221. The telescopic driver 23 is fixed to the support component by a flange 235.

[0034] It is understood that in this embodiment, the lateral pressing part 233 achieves lateral pressing of the object by being driven by the telescopic actuator 23. The lateral pressing part 233 is exposed in the inclined hole 221 through the sliding part 232. The sliding part 232 is connected to the telescopic rod of the telescopic actuator 23 and slides in cooperation with the inclined hole 221. Compared with the traditional telescopic actuator 23 being set on the outside of the support component, this can prevent debris from entering the telescopic actuator 23 and jamming the lateral push telescopic component.

[0035] Specifically, the support assembly in this embodiment includes a middle plate 22 and a main plate 21. The top surface of the main plate 21 is used to place the product 3 to be processed, and the bottom surface of the main plate 21 is connected to the middle plate 22. The middle plate 22 is mounted on the rotary table 1 via a shaft connecting block. At the same time, the support assembly provides support and fixation for several height clamping assemblies, several side-pushing telescopic assemblies, and vacuum adsorption assemblies.

[0036] In one specific embodiment of this application, the lateral clamping part 233 has a mating plane 234 that matches and abuts against the side wall of the product to be processed 3.

[0037] In one specific embodiment of this application, the lateral clamping part 233 has an arcuate convex surface that tangentially abuts against the side wall of the product 3 to be processed.

[0038] It is understood that in this embodiment, the lateral clamping part 233 clamps the side wall of the product to be processed 3 in two ways: one is to make contact through the mating plane 234, and the other is to make contact through the arc-shaped convex surface. The specific implementation method can be selected according to the actual situation.

[0039] It is understandable that when the contact is made through the mating plane 234, it is a surface contact, and the contact area reaches the theoretical maximum value, which is suitable for stable clamping. Increasing the contact area can reduce the unit pressure and prevent the workpiece sidewall from being deformed by force. When the contact is made through the arc-shaped convex surface, it is a narrow band contact, and the contact stress is lower than that of the surface contact, which can improve the service life of the equipment.

[0040] In one specific embodiment of this application, a material drop hole 24 is provided between the side-push telescopic component and the product 3 to be processed.

[0041] It is understood that in this embodiment, the material discharge hole 24 is provided to discharge waste or excess material generated during the processing, so as to prevent the accumulation of debris during the processing and affect the processing efficiency.

[0042] Combination Figure 2 , Figure 3 and Figure 4 As shown, in one specific embodiment of this application, the height clamping assembly includes a correspondingly arranged pressure claw 26 and a height limiting block. At least a portion of the pressure claw 26 is rotatably disposed on a rotating shaft 27 on the outside of the support assembly. A telescopic driver 25 disposed on the support assembly is connected to one end of the pressure claw 26 and drives the pressure claw 26 to rotate around the rotating shaft 27 and approach the height limiting block. The height limiting block is disposed on the top surface of the side wall of the support assembly.

[0043] It is understood that in this embodiment, the height clamping assembly achieves clamping of the product 3 to be processed through the synergistic action of the pressure claw 26 and the height limiting block. The telescopic actuator 25 is used to drive the pressure claw 26 to rotate around the rotating shaft 27, causing the pressure claw 26 to move closer to or away from the height limiting block, thereby achieving clamping or releasing of the product 3 to be processed. The height limiting block ensures that the clamping force will not exceed the set value.

[0044] In one specific embodiment of this application, the height limiting block includes a fixing block 281 disposed on the top surface of the side wall of the supporting component and a limiting block 282 at least partially disposed on the fixing block 281, and the remaining part of the limiting block 282 abuts against the top surface of the side wall of the product 3 to be processed.

[0045] Understandably, in this embodiment, the height limiting block is used to ensure that the horizontal height of different areas of the product 3 to be processed is consistent. The fixing block 281 provides stable support for the pressure limiting block 282, while the pressure limiting block 282 achieves precise control of the product height and the applied pressure through contact with the product 3 to be processed.

[0046] In one specific embodiment of this application, the vacuum adsorption assembly includes a gas storage tank and a vacuum suction pipe 292. The gas storage tank is disposed between the support assembly and the shaft turntable 1. One end of the vacuum suction pipe 292 is connected to the internal gas storage space of the gas storage tank, and the support assembly is provided with a plurality of suction holes 222 that communicate with the internal gas storage space of the gas storage tank.

[0047] It is understood that the gas storage tank in this embodiment is used to store gas. During product processing, the product 3 to be processed is clamped laterally and longitudinally by the high clamping assembly and the side-pushing telescopic assembly. The gas inside the gas storage tank is extracted through the vacuum suction pipe 292 connected to a vacuum pump or other suction equipment to form a vacuum environment. The vacuum environment inside the gas storage tank is transferred to the bottom surface of the product 3 to be processed through the suction port 222, thereby generating an adsorption force and realizing vacuum adsorption clamping.

[0048] Specifically, the specific working process of the universal telescopic machining positioning device provided in this embodiment is as follows:

[0049] First, the pressure claw 26 of the height clamping assembly is opened, and the side-push telescopic assembly is retracted, placing the product 3 to be processed into the supporting assembly. Second, the side-push telescopic assembly is controlled to clamp the three side walls of the product 3, while the pressure claw 26 of the height clamping assembly presses down to clamp the product 3. The vacuum adsorption assembly then vacuum-clamps the product 3, bringing the rotary table 1 horizontal for machining the inner cavity of the product 3. After machining the inner cavity, the short-side side-push telescopic assembly is retracted, and the rotary table 1 is rotated to the desired angle to machine the side walls of the product 3. After machining the side walls, the rotary table 1 is rotated to return the telescopic fixture 2 to its original position. The pressure claw 26 of the height clamping assembly is opened, the long-side side-push telescopic assembly is retracted, the vacuum adsorption assembly's vacuum force is disengaged, and the finished product is removed.

[0050] In another aspect, the present invention provides a universal telescopic processing equipment, including a universal telescopic processing positioning device.

[0051] It is understood that the universal telescopic processing equipment in this embodiment has the same beneficial effects as the universal telescopic processing positioning device, and will not be described in detail here.

[0052] It will be understood by those skilled in the art that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
