Description

Technical Field

[0001] The utility model belongs to the technical field of clamping equipment, and in particular relates to a fixing mechanism used for edge grinding. Background Art

[0002] In the metal processing industry, especially in the edge processing of metal materials, a fixed clamping mechanism is often needed to keep the workpiece stable for precise edge grinding. Traditional fixed clamping mechanisms usually use magnetic adsorption to fix the workpiece. This design has the following problems in actual operation:

[0003] 1. Material limitation: Since the magnetic attraction method depends on the magnetism of the material, it cannot effectively fix non-magnetic materials, such as 304 stainless steel. This greatly limits the scope of application of the clamping mechanism. For those applications that require non-magnetism, the traditional clamping mechanism cannot meet the needs.

[0004] 2. Low processing accuracy: During the edge grinding process, due to the uneven magnetic adsorption or the shape of the workpiece itself, the workpiece is prone to deflection or movement, resulting in reduced processing accuracy. Especially in high-precision processing, this deflection may lead to a decrease in yield and increase production costs.

[0005] 3. Low efficiency: Traditional magnetic clamping mechanisms can usually only fix one workpiece at a time, which means that in batch production, repeated clamping and adjustment take a long time, thereby reducing the overall processing efficiency.

[0006] In order to solve the above problems, it is necessary to design a new type of fixing mechanism that can adapt to workpieces of different materials, improve processing accuracy, and improve processing efficiency. Utility Model Content

[0007] In view of the deficiencies in the above prior art, the utility model provides a fixing mechanism for edge grinding, including a base, a pressure plate and a backrest. The base is provided with a placement groove, the pressure plate is assembled on the top of the base, the pressure plate and the placement groove cooperate to form a limiting cavity for placing the material, and one end of the material for processing is exposed outside the limiting cavity. The backrest is assembled on one side of the limiting cavity, and the backrest is provided with a positioning flange for axial positioning of the material. The base, the pressure plate and the backrest cooperate to fix the material, so as to facilitate the edge grinding equipment to perform edge grinding on the material.

[0008] Preferably, the bottom of the placement groove is provided with a plurality of positioning grooves for positioning the material, and the positioning grooves are V-shaped structures. The provision of the positioning grooves can strengthen the positioning of the material, and can ensure that the spacing between the material parts is equal, which is convenient for edge grinding.

[0009] Preferably, the ratio of the width of the placement groove to the maximum axial diameter of the workpiece is not greater than 25, so as to ensure the pressing force of the pressure plate on the workpiece and avoid the placement groove being too wide, resulting in insufficient pressing force on the workpiece located in the center of the placement groove, causing it to rotate during edging processing.

[0010] Preferably, the pressing plate is connected and fastened to the base by a plurality of vertical fastening screws, and the vertical fastening screws are arranged on both sides of the placement groove. A first adjustment groove is arranged on the pressing plate, and the head of the vertical fastening screw is located in the first adjustment groove. The arrangement of the first adjustment groove enables the pressing plate to be adjusted along the axial direction of the material, so that the fixing mechanism can be used to fix materials of different specifications.

[0011] Preferably, the backrest and the base are connected and fastened by a plurality of transverse fastening screws. A second adjustment slot is provided on the pressure plate, and the head of the transverse fastening screw is located in the second adjustment slot. The second adjustment slot enables the backrest to be adjusted in height to generate a radial force on the end of the material, so as to strengthen the fixation of the material and prevent the material from deflecting during the edge grinding process.

[0012] Preferably, a support column is installed at the bottom of the backrest, and an adjusting nut is installed at the bottom of the support column. The adjusting nut can cooperate with the second adjusting slot to adjust the height of the backrest.

[0013] Preferably, the height of the positioning flange is not greater than the maximum radius of the workpiece, so that the end portion of the workpiece is partially exposed, making it convenient for workers to observe the rotation of the workpiece during the edging process.

[0014] Preferably, the backrest is made of Cr12 alloy steel, which has good wear resistance and ensures the positioning accuracy of the positioning flange.

[0015] Compared with the prior art, the utility model has the following beneficial effects: it can effectively fix various workpieces including non-magnetic materials, ensure stability during the processing, thereby improving processing accuracy, and can clamp multiple workpieces at the same time, thereby improving processing efficiency.

The ratio of the groove width of the placement groove 11 to the maximum axial diameter of the material 40 is not greater than 25, so as to ensure the pressing force of the pressing plate 20 on the material 40, and avoid the placement groove 11 being too wide, and the material 40 located at the center of the placement groove 11 being insufficient in the pressing force, which causes it to rotate during edge grinding. The pressing plate 20 is assembled on the top of the base 10, and the pressing plate 20 and the placement groove 11 cooperate to form a limiting cavity for placing the material 40, and one end of the material 40 for processing is exposed outside the limiting cavity.
