This operation is relatively cumbersome, and the metal part is prone to positional deviation when clamping and positioning it again in subsequent operations, which affects the processing accuracy and quality of the metal part. To address these issues, we propose a metal part clamping fixture to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example: Figure 1-6As shown, this utility model provides a fixing fixture for metal part processing, including a fixing base 1. Two positioning mechanisms 2 are fixedly installed on the top of the fixing base 1. A limiting frame 3 is provided on the side of the top of the fixing base 1 away from the positioning mechanisms 2. Two support frames 4 are provided on the side of the limiting frame 3 close to the positioning mechanisms 2. Two first lifting cylinders 41 are provided at the bottom of the support frame 4. The first lifting cylinders 41 are fixedly installed on the top of the fixing base 1, and the driving end of the first lifting cylinders 41 is fixedly installed at the bottom of the support frame 4. A support pad 42 is fixedly installed on the upper surface of the support frame 4. By setting two support frames 4 and using the first lifting cylinders 41 to control the corresponding support frames 4 to lift and lower, the processing part of the metal part is supported, improving the stability of subsequent metal part processing.
[0028] The positioning mechanism 2 includes a mounting bracket 21, which is fixedly mounted on the top of the fixed base 1. A rotating ring frame 22 is fixedly mounted on the top of the mounting bracket 21. An auxiliary frame 221 is integrally formed on the top of the rotating ring frame 22. A rotating ring bracket 23 is rotatably mounted in the rotating ring frame 22. Multiple connecting brackets 24 arranged in a ring array are fixedly mounted on the inner side of the rotating ring bracket 23. Positioning ring brackets 25 are fixedly mounted on the opposite ends of the multiple connecting brackets 24. Multiple positioning slide rods 26 arranged in a ring array are slidably mounted on the positioning ring bracket 25. Positioning discs 28 are provided at opposite ends of the positioning slide rods 26. Positioning pads 29 are fixedly provided on the side of the positioning discs 28 away from the positioning slide rods 26. Telescopic cylinders 27 corresponding to the positioning slide rods 26 are fixedly installed on the rotating ring frame 23. The drive end of the telescopic cylinder 27 is fixedly installed with the corresponding positioning slide rod 26. In use, the metal part to be processed is passed through the positioning ring frame 25 and placed between multiple positioning slide rods 26. Then, multiple telescopic cylinders 27 are activated to drive the corresponding positioning slide rods 26 to slide until multiple positioning pads 29 contact the metal part, thereby positioning the metal part.
[0029] A geared ring is provided on the outer side of the rotating ring frame 23. A transmission gear 231 is movably mounted in the auxiliary frame 221. A transmission shaft 232 is fixedly installed in the middle of the transmission gear 231. The transmission shaft 232 is rotatably mounted on the auxiliary frame 221. The transmission gear 231 and the geared ring are meshed together. One end of the transmission shaft 232 extends out of the outer side of the auxiliary frame 221 and is fixedly mounted with a worm gear 233. A worm 234 is meshed on the outer side of the worm gear 233. The worm 234 is rotatably mounted on the outer wall of the auxiliary frame 221. The outer wall of the auxiliary frame 221 is close to... A first motor 235 is fixedly installed on one side of the worm 234. The drive end of the first motor 235 is fixedly installed on the shaft end of the worm 234. By turning on the first motor 235, the worm 234 is driven to rotate the worm wheel 233, the transmission shaft 232 and the transmission gear 231, thereby controlling the rotation of the gear ring and the rotating ring frame 23, and then controlling the rotation of the positioning ring frame 25 and the positioning metal part. This directly flips and adjusts the processing position of the metal part, preventing positional deviation of the metal part and affecting the processing accuracy and quality of the metal part.
[0030] A connecting shaft 281 is fixedly installed on the side of the positioning plate 28 near the positioning slide rod 26. The connecting shaft 281 is slidably engaged with the side of the positioning slide rod 26 near the positioning plate 28. A limit pin 282 is vertically installed on the side of the positioning slide rod 26 near the positioning plate 28. The limit pin 282 moves through the connecting shaft 281 to install the positioning plate 28, thereby facilitating the removal of the limit pin 282 to disassemble the positioning plate 28. Furthermore, positioning plates 28 of different shapes can be replaced and installed according to the shape of the metal parts to effectively contact and position the metal parts.
[0031] Both sides of the bottom end of the limiting frame 3 are fixedly installed with sliding blocks 31, which are slidably engaged with the top of the fixed base 1. A limiting pad 301 is fixedly installed on the side of the limiting frame 3 near the positioning mechanism 2. A drive slide 32 is fixedly installed in the middle of the bottom end of the limiting frame 3, which is slidably engaged with the top of the fixed base 1. A drive screw 33 is threadedly installed in the middle of the drive slide 32, and the drive screw 33 is rotatably mounted on the fixed base 1. A second motor 34 is fixedly installed on the side end of the fixed base 1. The drive end of the second motor 34 and the shaft end of the drive screw 33 are fixedly installed. By turning on the second motor 34... The drive screw 33 is rotated, which drives the drive slide 32 to control the limiting frame 3 to slide horizontally, thereby adjusting the distance between the limiting frame 3 and the support frame 4. When the metal part passes through the positioning ring frame 25, the processing end of the metal part contacts the limiting pad 301 on the limiting frame 3, which assists in limiting the processing end of the metal part, so that the processing part of the metal part is supported on the two support frames 4, so as to accurately process the processing part of the metal part and improve processing efficiency. Since the distance between the limiting frame 3 and the support frame 4 can be adjusted, the position of the processing end of the metal part can be flexibly limited according to different processing parts of the metal part.
[0032] Working principle: When in use, firstly, according to the position of the processing part of the metal part, the second motor 34 is turned on to control the drive screw 33 to rotate, thereby driving the drive slide 32 to control the limit frame 3 to slide horizontally, thereby adjusting the distance between the limit frame 3 and the support frame 4.
[0033] Subsequently, the metal part to be processed is passed through the positioning ring frame 25 and placed between multiple positioning slide rods 26, so that the processing end of the metal part contacts the limiting pad 301 on the limiting frame 3, and the processing end of the metal part is assisted in limiting it, so that the processing part of the metal part is supported on two support frames 4, so that the processing part of the metal part can be precisely processed.
[0034] Subsequently, multiple telescopic cylinders 27 are activated to drive the corresponding positioning slide rods 26 to slide until multiple positioning pads 29 contact the metal parts to position the metal parts. Then, the first lifting cylinder 41 is used to control the corresponding support frame 4 to rise, supporting the processing part of the metal parts and improving the stability of subsequent metal part processing.
[0035] Specifically, by activating the first motor 235 to drive the worm gear 234 to rotate the worm wheel 233, the transmission shaft 232 and the transmission gear 231, the gear ring and the rotating ring frame 23 are controlled to rotate, which in turn controls the positioning ring frame 25 and the positioned metal part to rotate, directly flipping and adjusting the processing position of the metal part, preventing the metal part from having positional deviations, which would affect the processing accuracy and quality of the metal part;
[0036] Before rotation, the first lifting cylinder 41 can be activated to control the corresponding support frame 4 to descend, making it easier for the metal parts to flip.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
