Description

Technical Field

[0001] This utility model relates to the field of stainless steel processing technology, specifically to a clamping device for processing stainless steel stamping parts. Background Technology

[0002] Stainless steel stampings are parts made by stamping stainless steel sheets into specific shapes and sizes. Currently, after the production of stainless steel stampings, they are usually ground or otherwise processed. Clamping equipment is used in the processing. However, when clamping rectangular stainless steel stampings, it is not possible to quickly complete the internal and external clamping, which affects the internal and external grinding operations of stainless steel stampings. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a clamping device for processing stainless steel stamping parts. The clamping plate that opens outward can press and position the inner side of the stamping part, and the clamping plate that moves inward can clamp and fix it on the outer side of the stamping part, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a clamping device for processing stainless steel stamping parts, including a panel and a stamping part to be processed. The stamping part is placed on the surface of the panel. Multiple positioning holes are distributed in a rectangular structure on the surface of the panel. Each positioning hole is vertically provided with a clamping plate. One end of each clamping plate extends into the interior of the stamping part and abuts against the inner side of the stamping part. The other end of each clamping plate is thickened to form an inclined guide portion. The guide portion is provided on the inner side of the clamping plate. A drive mechanism is provided between the multiple clamping plates to synchronously drive the multiple clamping plates to open outward. The end of each clamping plate away from the panel is inclinedly provided with a push plate. A fixing plate is installed on the multiple push plates.

[0005] As a preferred technical solution, the drive mechanism includes a ring body, a first cylinder, and multiple pressure plates. The ring body is disposed between multiple clamping plates. The piston rod of the cylinder extends into the central hole of the ring body and is equipped with multiple connecting rods. The other end of each connecting rod is mounted on the inner ring surface of the ring body. The pressure plates are rectangular in structure and mounted on the ring body. The pressure plates are all arranged perpendicularly to the guide section. A fixing frame is mounted on the outside of the first cylinder. The other end of the fixing frame is bent and mounted on the panel.

[0006] As a preferred technical solution, a second cylinder is installed on the panel, a connecting plate is installed on the piston rod of the second cylinder, and the other end of the connecting plate is installed on the fixed plate.

[0007] As a preferred technical solution, multiple support columns are installed on one side of the panel.

[0008] As a preferred technical solution, both sides of the positioning port are provided with sliding grooves, and both sides of the clamping plate are equipped with sliders directly opposite the sliding grooves, with the sliders slidably disposed in the sliding grooves.

[0009] As a preferred technical solution, compression springs are installed on the outer side of the clamping plate, and the other end of each compression spring is installed on the inner wall of the positioning port.

[0010] As a preferred technical solution, all corners of the clamping plate facing the push plate are chamfered.

[0011] The beneficial effects of this utility model are as follows: This utility model has a simple structure. After the stamped part is placed on the panel, the descending pressure plate can squeeze the guide part outward, so that the clamping plate can open outward at the same time until it abuts against the inner side of the stamped part, so that the outer surface of the stamped part is exposed, which facilitates the surface grinding operation. After the stamped part is flipped over, the rising push plate can squeeze the clamping plate inward, so that the clamping plate can move closer together at the same time and clamp on the outer side of the stamped part, so that the inner cavity of the stamped part is exposed, which facilitates the inner wall grinding operation.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping device for processing stainless steel stamping parts according to the present invention includes a panel 1 and a stamping part 2 to be processed. The stamping part 2 is placed on the surface of the panel 1. Multiple positioning holes 3 are distributed in a rectangular structure on the surface of the panel 1. Each positioning hole 3 is vertically provided with a clamping plate 8. One end of each clamping plate 8 extends into the interior of the stamping part 2 and abuts against the inner side of the stamping part 2. The other end of each clamping plate 8 is thickened to form an inclined guide portion 9. The guide portion 9 is provided on the inner side of each clamping plate 8. A drive mechanism is provided between the multiple clamping plates 8 to synchronously drive the multiple clamping plates 8 to open outward. The end of each clamping plate 8 away from the panel 1 is inclinedly provided with a push plate 7. A fixing plate 6 is installed on the multiple push plates 7.

[0022] This device is suitable for rectangular stamping parts of equal width, enabling simultaneous clamping and fixing of all four sides of such stamping parts in one operation.

[0023] In this embodiment, the driving mechanism includes a ring body 11, a first cylinder 14, and multiple pressure plates 10. The ring body 11 is disposed between multiple clamping plates 8. The piston rod of the cylinder extends into the central hole of the ring body 11 and is equipped with multiple connecting rods. The other end of each connecting rod is mounted on the inner ring surface of the ring body 11. The pressure plates 10 are rectangular and mounted on the ring body 11. The pressure plates 10 are all perpendicular to the guide portion 9. A fixing frame is mounted on the outside of the first cylinder 14. The other end of the fixing frame is bent and mounted on the panel 1.

[0024] In this embodiment, a second cylinder 12 is installed on the panel 1, and a connecting plate 13 is installed on the piston rod of the second cylinder 12. The other end of the connecting plate 13 is installed on the fixing plate 6.

[0025] In this embodiment, multiple support columns 5 are installed on one side of the panel 1.

[0026] In this embodiment, both sides of the positioning port 3 are provided with sliding grooves, and both sides of the clamping plate 8 are equipped with sliders directly opposite the sliding grooves. The sliders are slidably disposed in the sliding grooves. The clamping plate can be positioned by the sliders and the sliding grooves, so that the clamping plate can only move back and forth along the sliding grooves, thus preventing it from falling out of the positioning port.

[0027] In this embodiment, compression springs 4 are installed on the outer side of the clamping plate 8, and the other end of the compression springs 4 is installed on the inner wall of the positioning port 3. After the pressure plate and push plate are removed from the clamping plate, the compression springs can pull the clamping plate back to its original position, which facilitates the clamping plate to close or open again next time.

[0028] In this embodiment, the corners of the clamping plate 8 facing the push plate 7 are all chamfered. During the process of the push plate rising, the chamfering allows the push plate to press the clamping plate inward more smoothly, so that the clamping plate moves along the slide groove.

[0029] When in use, if the outer surface of the stamped part needs to be machined, the second cylinder is started first, causing the piston rod of the second cylinder to extend. The movement of the piston rod drives the fixed plate and the push plate. The push plate can squeeze the clamping plate, causing the clamping plate to move inward along the positioning hole. This makes the rectangular structure formed by the clamping plates smaller than the inner cavity of the stamped part, allowing the stamped part to be fitted over the outside of multiple clamping plates. After the fitting is completed, the push plate returns to its position, and the first cylinder is started, causing the piston rod of the first cylinder to extend. The movement of the piston rod drives the ring and the pressure plate. The descending pressure plate can squeeze the guide part, causing the clamping plate to move outward along the positioning hole until it contacts the inner side of the stamped part, exposing the outer surface of the stamped part for easy surface grinding.

[0030] Conversely, when grinding the inner cavity of a stamped part, the stamped part is flipped over so that the inner cavity faces upward. At this time, the clamping plate is first moved outward, and then the clamping plate is moved inward and clamped on the outer side of the stamped part, which facilitates the grinding operation of the inner cavity.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
