[0021] like Figures 1-3 As shown, a clamping fixture for manufacturing surgical light mounting brackets is used to mount a surgical light mounting bracket 100 onto a processing equipment. The fixture involves machining the upper surface S1 of the surgical light mounting bracket 100 and the stepped surface S2 surrounding the upper surface S1, and creating a through hole S3 on the stepped surface S2. The clamping fixture includes a mounting base 1, which is fixedly mounted on the processing equipment. A contour block 2 is fixedly mounted on the mounting base 1. The upper surface of the contour block 2 has a contour groove 21 that fits the lower surface of the surgical light mounting bracket 100. After the surgical light mounting bracket 100 is placed into the contour groove 21, the contour groove 21 supports the lower surface of the surgical light mounting bracket 100. The contour block 2 is provided with a first clamping block 3, which is detachably connected to the contour block 2. The first clamping block 3 is used to press down the stepped surface S2 of the surgical lamp mounting bracket 100 during processing so as to process the upper end surface S1 of the surgical lamp mounting bracket 100. The contour block 2 is provided with a second clamping block 4, which is detachably connected to the contour groove 21. The second clamping block 4 is used to press down the upper end surface S1 of the surgical lamp mounting bracket 100 during processing so as to process the stepped surface S2 of the surgical lamp mounting bracket 100 and the through hole S3 on the stepped surface S2.
[0022] In the specific processing, first, the surgical lamp mounting frame 100 is placed into the profiling groove 21, so that the profiling groove 21 supports the lower end surface of the surgical lamp mounting frame 100; then the first clamping block 3 is installed on the profiling block 2, the step surface S2 is pressed by the first clamping block 3, and then the upper end surface S1 of the surgical lamp mounting frame 100 is turned by the processing equipment; after the upper end surface S1 of the surgical lamp mounting frame 100 is processed, the second clamping block 4 is installed into the profiling groove 21, so that the second clamping block 4 abuts against the upper end surface S1 of the surgical lamp mounting frame 100, and the surgical lamp mounting frame 100 is pressed by the cooperation of the second clamping block 4 and the profiling block 2; then the first clamping block 3 is detached from the profiling block 2, and then the processing equipment can turn and drill the step surface S2 on the surgical lamp mounting frame 100.
[0023] When the clamping tool is used for processing, the direction of pressing the workpiece is adopted instead of the existing clamping mode, so that even if the width of the step surface S2 of the surgical lamp mounting frame 100 is smaller and the thickness of the upper end surface S1 is thinner, the clamping deformation does not occur, which guarantees the yield of the processing and is beneficial to the processing requirements of high quality and high efficiency.
[0024] In order to improve the stability of the processing, the number of the first clamping block 3 is two, and the two first clamping blocks 3 are symmetrically distributed on the left and right sides of the profiling groove 21; the step surface S2 of the surgical lamp mounting frame 100 is pressed by the two first clamping blocks 3 respectively, so that the two sides of the surgical lamp mounting frame 100 are stressed at the same time, which can improve the stability of the processing, improve the processing precision and the yield. In other embodiments, the number of the first clamping block 3 can also be any other number.
[0025] In order to facilitate the detachment of the first clamping block 3, the first fixing screw 5 is arranged on the first clamping block 3, and the first fixing screw 5 is screwed into the profiling block 2 after penetrating the first clamping block 3. By tightening the first fixing screw 5, the first clamping block 3 can abut against the upper end surface of the profiling block 2, so that the first clamping block 3 can press the surgical lamp mounting frame 100 in the profiling groove 21; after the upper end surface S1 of the surgical lamp mounting frame 100 is processed, the first clamping block 3 can be removed from the profiling block 2 by loosening the first fixing screw 5, so as to process the step surface S2 and the through hole S3 on the surgical lamp mounting frame 100.
[0026] In order to facilitate disassembly of the second clamp block 4, a second fixing screw 6 is arranged on the second clamp block 4, and the second fixing screw 6 is screwed with the profiling groove 21 after penetrating through the second clamp block 4. By tightening the second fixing screw 6, the second clamp block 4 can abut against the upper end surface S1 of the surgical lamp mounting frame 100 in the profiling groove 21, so that the second clamp block 4 can press the surgical lamp mounting frame 100 in the profiling groove 21; after processing is completed, the second fixing screw 6 can be loosened, and the second clamp block 4 can be taken off from the profiling block 2, so that the processed surgical lamp mounting frame 100 can be taken out from the profiling groove 21.
[0027] In order to facilitate machining of the through hole S3 on the stepped surface S2 of the surgical lamp mounting frame 100, an avoiding notch 41 is arranged at the corresponding position of the outer side wall of the second clamp block 4 and the through hole S3. By arranging the avoiding notch 41, the machining equipment can conveniently machine the through hole S3 on the stepped surface S2.
[0028] In order to facilitate assembly, in the embodiment, four positioning columns 22 are arranged on the lower end surface of the profiling block 2, and the four positioning columns 22 are distributed in a rectangular shape on the lower end surface of the profiling block 2. Corresponding positioning holes 11 are arranged at the corresponding positions of the positioning columns 22 on the upper end surface of the mounting base 1, and the positioning columns 22 are respectively inserted into the corresponding positioning holes 11. When the clamping tool is assembled, the positioning columns 22 and the positioning holes 11 can be aligned, so that the profiling block 2 and the mounting base 1 can be quickly aligned and assembled, and then the profiling block 2 and the mounting base 1 can be connected and fixed by screws. The cooperation of the positioning columns 22 and the positioning holes 11 can quickly align the profiling block 2 and the mounting base 1, and fix the cooperation position of the profiling block 2 and the mounting base 1, which can improve the assembly efficiency and save time on one hand, and on the other hand, the profiling block 2 and the mounting base 1 are aligned, that is, the machining origin of the profiling groove 21 and the machining origin of the mounting base 1 are aligned, so that the machine adjustment time before machining can be reduced, and the efficiency can be improved.
