Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a punching positioning device for sheet metal parts. Background Technique

[0002] At present, in the field of sheet metal processing, punching operation is a common technological process. Traditional punching positioning devices for sheet metal mostly adopt methods such as panel positioning, die positioning or fixture positioning. Although these positioning methods can meet the basic punching positioning requirements, there are many deficiencies. Panel positioning is simple and easy to implement, but the positioning accuracy is low and it is easily interfered by external forces; die positioning has relatively high accuracy, but the design and processing costs of the die are high, and the die replacement is complex; fixture positioning can improve the positioning accuracy, but it also requires additional design and manufacturing costs. Therefore, the existing technology is difficult to meet the requirements of high-precision, high-efficiency and low-cost punching positioning for sheet metal. Content of the Utility Model

[0003] The purpose of the utility model is to provide a punching positioning device for sheet metal parts to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A punching positioning device for sheet metal parts, including an adjusting device, a top plate and a clamping assembly. One side of the top of the top plate is provided with a sliding groove. Two clamping assemblies are slidably installed on the top of the top plate through the sliding groove. A clamping plate is arranged inside the clamping assembly. A threaded sleeve is installed at the bottom of the clamping plate. Two knobs are installed through the top of the clamping plate in a threaded manner. A suction cup is installed at the bottom of the knob. A side frame is installed at the bottom of the top plate. An adjusting device is installed inside the side frame through a bearing.

[0005] During use, the workpiece to be punched is placed on the top plate. By adjusting the adjusting device, the relative positions of the two clamping assemblies can be adjusted to adapt to sheet metal parts of different sizes. When the two clamping assemblies clamp the sheet metal part, the staff can rotate the knob to make the suction cup clamp the sheet metal part, ensuring that the sheet metal part will not shift or shake during the punching process. When the device is in use, through the coordinated linkage of the adjusting device and the clamping assembly, the device can adapt to sheet metal parts of different sizes, improving the versatility and flexibility of the device. Moreover, the device has a simple structure and convenient operation, without complex die replacement or fixture adjustment, reducing the operation difficulty and cost, without designing and processing expensive dies or fixtures, reducing the manufacturing cost, and at the same time improving the production efficiency with low cost.

[0006] Preferably, the adjusting device is composed of a target lead screw and a turntable, and the target lead screw penetrates through the threaded sleeve.

[0007] The staff can rotate the object lead screw through the turntable, and by rotating the object lead screw, the position of the clamping assembly on the side frame can be adjusted to clamp the workpiece.

[0008] Preferably, a weight-reducing hole is provided inside the side frame, a bottom frame is installed at the bottom of the side frame, and bolts are installed through the outside of the bottom frame.

[0009] The weight of the side frame can be reduced through the weight-reducing hole, the manufacturing materials can be reduced, and the economic cost can be lowered.

[0018] The following specific embodiments are provided to assist the reader in obtaining a comprehensive understanding of the methods, apparatuses, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatuses, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein, but rather changes that will be apparent after understanding the disclosure of this application may be made, except for operations that must occur in a specific order. Additionally, descriptions of features known in the art may be omitted for increased clarity and conciseness.

[0019] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatuses, and / or systems described herein that will be apparent after understanding the disclosure of this application.

[0020] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, it can be directly "on," "connected to," "bonded to," "above," or "covering" the other element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on," "directly connected to," "directly bonded to," "directly above," or "directly covering" another element, there can be no other elements intervening therebetween.

[0021] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0022] Although terms such as "first," "second," and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another.
