[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a five-axis machining center parts processing fixture, including a base 4, a clamping component 3 is provided inside the base 4, two clamping members 5 are connected to the side of the clamping component 3, a bracket 1 is installed on the top of the base 4, lighting mechanisms 2 are provided on both sides of the bracket 1, a moving component 7 is provided inside the bracket 1, a lifting mechanism 8 is embedded in the moving component 7, and a manipulator 6 is connected to the bottom end of the lifting mechanism 8.

[0023] Specifically, the clamping assembly 3 includes a support block 31, a slider 32, a screw 33, a slide groove 34 and a replacement assembly 35. The base 4 is provided with a slide groove 34, and the slide groove 34 is embedded with a screw 33. Two sliders 32 are sleeved on the surface of the screw 33. The top of the slider 32 is connected to the support block 31, and the surface of the support block 31 is connected to the replacement assembly 35. The threads on the surfaces at both ends of the screw 33 are in opposite directions.

[0024] By adopting the above technical solution, when the rotating screw 33 is meshed with the slider 32, the slide groove 34 limits the slider 32. Since the threads on the two end surfaces of the screw 33 are in opposite directions, the two sliders 32 can respectively drive the clamping members 5 on the side of the support block 31 to move toward each other to complete the clamping and fixing of the parts. The fixing operation is simple and the use effect is better.

[0025] Specifically, a positioning block 36 is sleeved on the surface of the screw rod 33 inside the base 4 . The positioning block 36 is in a circular ring structure. The surface of the slider 32 is tightly fitted with the inner wall of the slide groove 34 .

[0026] By adopting the above technical solution, the positioning block 36 plays a positioning role. Rotating the screw rod 33 can limit the rotation of the screw rod 33 and also make the control movement of the slider 32 more stable.

[0027] Specifically, the replacement component 35 includes a connecting sleeve 351, a connecting block 352, a fixing rod 353 and a spring 354. The surface of the support block 31 is connected to the connecting sleeve 351, the fixing rod 353 is embedded in the interior of the connecting sleeve 351, the spring 354 is connected between the fixing rod 353 and the connecting sleeve 351, the side of the clamping member 5 is connected to the connecting block 352, and the connecting block 352 and the connecting sleeve 351 are in a split structure.

[0028] By adopting the above technical solution, the fixing rod 353 is moved up and removed from the connecting block 352, and then the connecting block 352 is slid out of the connecting sleeve 351 to remove the clamping member 5. The appropriate clamping member 5 can be selected for use according to the shape of the part to make the device more applicable. Under the pulling force of the spring 354, the fixing rod 353 and the connecting block 352 are tightly plugged together to ensure that the clamping member 5 is firmly installed and positioned.

[0029] When the present embodiment is used, the part is placed on the base 4, and the positioning block 36 plays a positioning role. When the screw rod 33 is rotated and the meshing connection between the screw rod 33 and the slider 32 is connected, the slide groove 34 limits the slider 32. Because the thread directions of the surfaces at both ends of the screw rod 33 are opposite, the two sliders 32 can respectively drive the clamping members 5 on the side of the support block 31 to move toward each other to complete the clamping and fixing of the part. The fixing operation is simple and the use effect is better. The upward moving fixing rod 353 is moved out of the connecting block 352, and then the connecting block 352 is slid out of the connecting sleeve 351 to remove the clamping member 5. The appropriate clamping member 5 can be selected according to the shape of the part to use, so that the applicability of the device is higher. Under the pulling force of the spring 354, the fixing rod 353 and the connecting block 352 are tightly plugged together, so that the clamping member 5 can be installed and positioned firmly. The lifting mechanism 8 on the top of the bracket 1 can control the manipulator 6 to move down to grab the part. The lighting mechanism 2 improves the illumination to make the use effect of this five-axis machining center part processing fixture better.

[0033] By adopting the above technical solution, the motor 75 is started to drive the gear 73 to rotate. Under the meshing between the gear 73 and the rack 74, the limit block 71 and the limit groove 72 slide in a limited manner. The limit block 71 can drive the manipulator 6 at the bottom of the lifting mechanism 8 to move horizontally to adjust the position, which can make the use of the device better.

[0034] When this embodiment is used, the motor 75 is started to drive the gear 73 to rotate. Under the meshing between the gear 73 and the rack 74, the limit block 71 and the limit groove 72 slide in a limited manner. The limit block 71 can drive the manipulator 6 at the bottom of the lifting mechanism 8 to move horizontally to adjust the position, which can make the device more effective.

[0035] The motor 75 in the present invention is an existing disclosed technology, and the selected model is Z2D15W.

[0036] The structure and use principle of the bracket 1, lighting mechanism 2, base 4, clamping member 5, manipulator 6 and lifting mechanism 8 in the utility model have been disclosed in Chinese patent application No. 202221065179.5, which discloses a processing device for a five-axis machining center of complex parts. Its working principle is to place the parts on the base 4, and drive the clamping member 5 to clamp and fix the parts by rotating the rotating rods on both sides respectively. The lifting mechanism 8 on the top of the bracket 1 can control the manipulator 6 to move down to grab the parts.

Because the threads on the two end surfaces of the screw 33 are in opposite directions, the two sliders 32 can respectively drive the clamping members 5 on the side of the support block 31 to move toward each other to complete the clamping and fixing of the parts. The fixing operation is simple and the use effect is better. The fixing rod 353 is moved up and removed from the connecting block 352, and then the connecting block 352 is slid out of the connecting sleeve 351 to remove the clamping member 5. The appropriate one can be selected according to the shape of the part. The use of the clamping part 5 makes the device more applicable. Under the pulling force of the spring 354, the tight connection between the fixing rod 353 and the connecting block 352 can make the clamping part 5 installed and positioned firmly. The lifting mechanism 8 on the top of the bracket 1 can control the manipulator 6 to move down to grab the parts. The lighting mechanism 2 improves the illumination to make the use of this five-axis machining center part processing fixture better. The starting motor 75 drives the gear 73 to rotate.
