[0002] like Figure 1 The connector shown includes a main body and extensions on both sides. The bottom of the main body is beveled, and the extensions have several through holes. To process the through holes, the main body of the connector needs to be fixed with a bench vise before drilling. The bench vise will cause wear on both sides of the main body during the clamping process, resulting in damage to the appearance of the connector. Therefore, there is an urgent need for a positioning fixture that changes the clamping method of the connector. Utility Model Content

[0023] Example
[0024] Reference Figure 2-4As shown, this utility model discloses a machining and positioning fixture for a connector 20, including a base plate 10, a clamping cylinder 103 mounted on the base plate 10, and a first positioning block 101 mounted on one side of the clamping cylinder 103. The first positioning block 101 includes an inclined surface 1011 and a top abutment 1012. When fixed, the connector 20 is fastened onto the first positioning block 101, so that the inclined surface at the bottom of the connector 20 is in contact with the inclined surface 1011 of the first positioning block 101, and the top abutment 1012 abuts against the lower end of the inclined surface of the connector 20, which plays a limiting role. The first positioning block 101 supports the main body 201 of the connector 20, and the extensions 202 on both sides of the connector 20 extend out of both sides of the first positioning block 101 to facilitate drilling.
[0025] Reference Figure 2-4 As shown, the piston rod of the clamping cylinder 103 is equipped with a pressure rod 1031, which is positioned above the inclined surface 1011. The top abutment 1012 is located at one end of the inclined surface 1011 along the inclined direction. The first positioning block 101 has a through first clearance hole 1013. Specifically, the pressure rod 1031 includes a horizontal connecting rod and a Y-shaped top pressure rod 1031. One end of the connecting rod is installed on the piston rod of the clamping cylinder 103, and the top pressure rod 1031 is connected and fixed to the other end of the connecting rod. When the connecting piece 20 is placed on the first positioning block 101, the clamping cylinder 103 is controlled to push the connecting rod to drive the top pressure rod 1031 to clamp the connecting piece 20 on the first positioning block 101, thereby clamping and fixing the connecting piece 20. The use of a Y-shaped top pressure rod 1031 can increase the clamping range.
[0026] Reference Figure 2-4 As shown, a second positioning block 102 is installed on the side of the first positioning block 101 away from the clamping cylinder 103. Two limiting blocks 1021 are further provided on both sides of the second positioning block 102. Specifically, the extensions 202 on both sides of the clamped connector 20 extend beyond the first positioning block. When drilling the extensions 202, the lack of support due to the extensions extending from the first positioning block 101 can easily lead to vibration and dimensional errors. The second positioning block 102 is placed between the two extensions 202, and the limiting blocks 1021 are used to abut against the inner side of the extensions 202 to prevent vibration. Furthermore, the limiting blocks 1021 have a second clearance hole 1022 and a mounting hole 1023. The second clearance hole 1022 provides clearance space to prevent the drilling tool from hitting the second positioning block 102 when drilling the extensions 202. The mounting hole 1023 is used to lock the limiting blocks 1021 on both sides of the second positioning block 102, facilitating the replacement and installation of the limiting blocks 1021.
[0027] In this embodiment, the clamping cylinder 103, the first positioning block 101, and the second positioning block 102 are respectively locked to the base plate 10 by bolts, and the assembly method facilitates the processing and assembly of each module.
[0028] In addition, the base plate 10 is I-shaped, and there are fixing holes at both ends of the base plate 10 to reduce the weight of the base plate 10. The base plate 10 is installed and fixed on the machine base through the fixing holes to increase the overall stability.
[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
