Description

Technical Field

[0001] This invention relates to a side clamping device for machining the end face of support-type parts and its usage method, belonging to the field of fixture technology. Background Technology

[0002] In existing technologies, the end face (locating reference surface) of support-type parts (such as mounting section supports) is typically machined using a clamping plate. This method easily leaves tool marks on the machined surface (locating reference surface) during machining. These marks not only affect the appearance quality of the part but also impair the machining accuracy of the locating reference surface. Since the locating reference surface serves as a reference point for subsequent machining and assembly, its accuracy directly affects the positional accuracy of other parts machined based on it. Therefore, the presence of tool marks can lead to substandard machining quality of the entire part, thereby affecting the performance of the entire mechanical system.

[0003] Furthermore, if the machined surface (locating reference surface) is subjected to improper pressure or force during machining, it may cause a slight change in the position of the part in the fixture. Such a change is unacceptable in precision machining, thus increasing the risk of secondary positioning of the part. Secondly, since the pressure plate usually requires multiple clamping and adjustment, it not only increases the labor intensity of workers but also seriously wastes working time and reduces production efficiency. Summary of the Invention

[0004] To address the problems existing in the background art, the present invention provides a side clamping device for machining the end face of support-type parts and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a side-clamping device for machining the end face of a support-type part, comprising a clamping body, a horizontal pressure plate, clamping screws, springs, vertical supports, a vertical pressure plate, and a positioning block; the upper end of the clamping body is fixed with a positioning block, the upper surface of the positioning block is slidably limited to multiple vertical supports, each vertical support is fitted with a spring on its outer side, the upper end of each spring is respectively abutted to the upper end of the corresponding vertical support, and the lower end of each spring is abutted to the upper surface of the positioning block; the front of the clamping body is connected to the horizontal pressure plate and the vertical pressure plate; the left and right sides of the upper end of the clamping body are respectively threadedly connected to corresponding horizontally arranged clamping screws.

[0006] The clamping body includes an L-plate, a mounting part, and a support plate; the upper end of the horizontal plate of the L-plate is integrally formed and fixedly connected to the mounting part, and the upper surface of the mounting part is fixed with the support plate and a positioning block; the positioning block is set on the inner side of the support plate, and the upper end of the vertical plate of the L-plate and the upper end of the support plate are respectively threadedly connected to the corresponding clamping screws, and the two clamping screws are correspondingly set.

[0007] The positioning block includes a right positioning block and a left positioning block; the right positioning block and the left positioning block are arranged side by side, and the left positioning block is an inverted trapezoidal structure with a height higher than the right positioning block.

[0008] A method of using a side clamping device for machining the end face of a support-type part according to the present invention includes the following steps:

[0009] S1: Visually adjust until the upper surfaces of all vertical supports are on the same horizontal line;

[0010] S2: Align the end face of the part with the front face of the fixture body;

[0011] S3: Place the locating surface of the part on all vertical supports;

[0012] S4: Pre-tighten both sides of the part by using two clamping screws;

[0013] S5: Pre-tighten the lower end of the part by using horizontal and vertical pressure plates;

[0014] S6: In a machine tool, the scribing lines on a part are observed by using a dial indicator;

[0015] S7: Adjust the corresponding vertical support until the scribing line of the part is within 0.01;

[0016] S8: The lower end of the part is pressed by the horizontal and vertical pressure plates;

[0017] S9: The two sides of the part are tightened by two clamping screws;

[0018] S10: Double-check that the scribing lines on the part are within 0.01. Once you are sure that there are no errors, machine the positioning reference surface of the part.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention simplifies the adjustment and positioning process of the machined surface of a part by setting multiple vertical supports and springs, facilitating the alignment of the part's markings and ensuring precise relative positioning between the machined position and the casting structure. This improves the machining accuracy of the positioning reference surface and solves the problem of lack of top-mounted clamping in traditional clamping plate methods. It also avoids tool marks on the machined surface, ensuring the appearance quality of the part and the accuracy requirements of the positioning reference surface. Simultaneously, the double fixing method—using clamping screws on both sides of the part and a pressure plate at the bottom—ensures the stability of the machining process, effectively solving the problem of difficulty in clamping the positioning surface to the top surface and preventing joint marks caused by overlap between the machined and clamping surfaces. This not only improves the machining accuracy of the part but also reduces the labor intensity of workers and increases production efficiency. Attached Figure Description

[0025] A side-clamping device for machining the end face of a support-type part includes a clamping body 1, a horizontal pressure plate 4, clamping screws 9, springs 12, vertical supports 13, vertical pressure plates 14, and positioning blocks. A positioning block is fixed to the upper end of the clamping body 1. The upper surface of the positioning block slides with multiple vertical supports 13 and is limited by locking nuts. A spring 12 is fitted on the outer side of each vertical support 13. The upper end of each spring 12 abuts against the upper end of the corresponding vertical support 13, and the lower end of each spring 12 abuts against the upper surface of the positioning block. The front of the clamping body 1 is connected to the horizontal pressure plate 4 and the vertical pressure plate 14 respectively by corresponding fastening screws 2 and supports 3. The left and right sides of the upper end of the clamping body 1 are threadedly connected to corresponding horizontally arranged clamping screws 9.

[0026] The clamping body 1 includes an L-plate portion 101, a mounting portion 102, and a support plate 8.

The upper surface of the mounting portion 102 is fixed with the support plate 8 and a positioning block by corresponding positioning pins and screws. The positioning block is set on the inner side of the support plate 8. The upper end of the vertical plate of the L-plate portion 101 and the upper end of the support plate 8 are respectively threadedly connected to the corresponding clamping screws 9.

Distributing the positioning block into multiple parts reduces machining difficulty, makes it easier to ensure the machining accuracy of the positioning surface, facilitates positioning wear, and makes rework easier.
