Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a pressing plate used for positioning parts. Background Art
[0002] In part fixation, the pressure plate is the most commonly used fixing method. When the clamping screw is tightened, the traditional pressure plate will rub against the pressure plate to generate a torque force, which will drive the part and cause the part to deform. This deformation is not reflected in rough machining or relatively stable part processing, but it will affect the processing and inspection accuracy in thin-walled or inspection tooling. Moreover, in actual processing, the pressure plate is easy to be lost. Utility Model Content
[0003] In view of the above problems, the purpose of the present invention is to provide a pressing plate that can be quickly clamped, prevents the pressing plate from being lost, and avoids damage to parts.
[0004] The utility model is realized through the following technical solutions:
[0005] The cam is fixed on the workbench with a plurality of locking plates, the locking plates having the plurality of locking plates and the plurality of locking plates at the bottom.
[0006] Beneficial effects of the utility model:
[0007] The utility model has a simple structure. The pressure plate and the base are connected by a pin. The pressure plate is not separated from the fixture body when the parts are disassembled and assembled, which reduces the installation time of the pressure plate and prevents the pressure plate from being lost. The movement of the pressure plate when it is pressed is reduced by clearance fit, and a copper sheet is welded on the front end of the pressure plate to prevent scratches on the parts.

[0013] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0014] It should be noted that the structures, proportions, sizes, etc. depicted in the drawings of this specification are only used to match the contents disclosed in this specification for the understanding and reading of those familiar with this technology, and are not used to limit the conditions for the implementation of this utility model. Therefore, they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed in this utility model without affecting the efficacy and purpose of the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", etc. quoted in this specification are only for the convenience of description and are not used to limit the scope of the implementation of this utility model. Changes or adjustments in their relative relationships should also be considered as the scope of the implementation of this utility model without substantially changing the technical content.
[0015] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. It should be noted that the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device. Example 1
[0016] like Figure 1-Figure 3 The pressure plate for positioning parts shown in the figure comprises: a base 1, a pressure plate 2, a fixing screw 3, a tightening screw 4, a limiting device 5, a latch 6, a positioning pin 7 and a retaining ring 8.
[0017] The base 1 is provided with fixing screws 3 for fixing the base 1 on the workbench;
[0018] The front end of the pressure plate 2 extends out of the base 1 and is used to press the parts, and the rear end is rotatably connected to the top rear end of the base 1 through a pin 6; the pressure plate 2 is connected to the front end of the base 1 through a clamping screw 4, and the pin 6 only serves as a connection to prevent the pressure plate from being lost; a copper sheet is provided at the front end of the pressure plate 2 to prevent scratches on the parts; a protrusion is provided at the bottom of the pressure plate 2, and a groove is provided on the base 1 that is clearance-matched with the protrusion on the pressure plate 2 to limit the left and right displacement of the pressure plate 2.
[0019] The limiting device 5 is sleeved on the latch 6 , and the limiting device 5 is an E-shaped clip spring, which is used to limit the pressure plate 2 .
[0020] The positioning pin 7 is provided at the bottom of the base 1 and is used for positioning when the base 1 is installed.
[0021] The retaining ring 8 is arranged at the hole opening of the pressing plate 2 for installing the clamping screw 4 to prevent the clamping screw 4 from falling off and being lost when the pressing plate 2 is turned over.
[0022] Working principle:
[0023] When in use, the base 1 is positioned by the positioning pin 7 and installed on the workbench by the fixing screw 3, and then the pressure plate 2 is rotated to press the front end of the pressure plate 2 on the part, and then the clamping screw 4 is tightened to complete the part positioning; loosen the clamping screw 4, lift the pressure plate 2, and the part can be taken out. At the same time, the elastic retaining ring 8 installed at the hole where the clamping screw 4 is installed prevents the clamping screw 4 from popping out. Example 2
[0024] The only difference between Example 2 and Example 1 is that the limiting device 5 is a torsion spring. When the tightening screw 4 is loosened, the pressure plate 2 will bounce up due to the torsion spring, which is convenient for operators to use.
[0025] The protection scope of the present invention is not limited to the technical solutions disclosed in the specific implementation methods. Any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
