[0046] like Figure 3 , Fig. 9 and Fig.10 As shown, a fixture for processing non-standard parts for precision machine tools of the present invention, the connecting component 12 includes a vertical plate 1201 arranged on a fixed plate 1101, an electric push rod 3 1202 is installed on the vertical plate 1201, a mounting block 1203 is provided at the output end of the electric push rod 3 1202, a bearing on the mounting block 1203 is connected to a rotating rod 1204, a rotating gear 1205 meshing with a spur rack 1105 is fixedly sleeved on the rotating rod 1204, and the rotating rod 1204 is connected to the shaft 801 via a clamping component 13.
[0047] like Figure 7 and Fig.10 As shown, a fixture for non-standard parts processing for precision machine tools of the present invention, the clamping assembly 13 includes a clamping gear 1301 fixedly mounted on a rotating rod 1204, a turntable 1302 is provided at the end of the shaft 801, and a limiting gear ring 1303 meshing with the clamping gear 1301 is provided on the turntable 1302.
[0048] Working principle: Put the workpiece on the bearing plate 3. When clamping the workpiece, start the hydraulic push rod 401. The output end of the hydraulic push rod 401 pulls down to drive the movable plate 402 to move downward. The movable plate 402 drives one end of the connecting rod 501 to move downward, so that the other end of the connecting rod 501 drives the slider 502 and the T-block 503 to move inward on the bearing plate 3, so that the sliders 502 are close to each other.
[0049] The slider 502 drives the support block 6 to move, and the support block 6 drives the clamping assembly 7, the pressing assembly 8, the pressing assembly 9, the adjusting assembly 11, the connecting assembly 12 and the clamping assembly 13 to move synchronously, and the multiple clamping blocks 704 move synchronously to clamp the workpiece until the clamping blocks 704 tightly fit and clamp the sides of the workpiece and press the top of the workpiece. Since the spring 804 exerts a supporting force on the clamping block 802, when the height of the workpiece is lower than the height of the clamping block 802 in the natural state, the electric push rod 3 1202 is started, and the output end of the electric push rod 3 1202 drives the mounting block 1203 to move, and the mounting block 1203 drives the rotating rod 1204 and the rotating gear 1205 to move until the clamping gear 1301 on the rotating rod 1204 is separated from the limiting gear ring 1303, and the rotating gear 1205 is separated from the spur rack 1105;
[0050] Start the electric push rod 901, the output end of the electric push rod 901 drives the horizontal plate 902 to move, the horizontal plate 902 drives the connecting rod 903 to move, the connecting rod 903 drives the connecting frame 904 to move, the connecting frame 904 drives the lower pressing wheel 905 to move, when the lower pressing wheel 905 contacts the clamping block 802, a force is generated on the clamping block 802, the clamping block 802 rotates around the axis point of the shaft 801, the clamping block 802 drives the clamping wheel 803 to move until the clamping wheel 803 contacts the top of the workpiece, when the clamping block 802 rotates, the spring 804 is forced to compress, so as to achieve three-dimensional clamping of the workpiece;
[0051] The height of the workpiece is relatively high and the side cannot be fully clamped, so it is necessary to adjust the height of the clamping block 802 and the clamping block 704 at the same time; when the sides of the workpiece are clamped first, when the clamping blocks 704 are close to each other, one side needs to be fine-tuned, so the solenoid valve 1 706 is opened, the solenoid valve 2 1107 is closed, and the electric push rod 2 1001 is started. The output end of the electric push rod 2 1001 drives the lifting piston 1003 to move in the cylinder 3 1002, so that the gas in the cylinder 3 1002 enters the cylinder 1 701 through the connecting block 1004 and the conduit 1 705, so that the pressure in the cylinder 1 701 increases, so that the gas in the cylinder 1 701 drives the push piston 702 to move, and the push piston 702 drives the push rod 703 to move, so that the push rod 703 drives the clamping block 704 to move, until the clamping block 704 on one side contacts the side of the workpiece, so as to achieve fine-tuning clamping of the side of the workpiece;
[0052] When the height of the workpiece is high, that is, when the height of the workpiece exceeds the height of the clamping block 802 in the free state, it is necessary to adjust the height of the clamping block 802, and start the electric push rod 1202 in the reverse direction. The output end of the electric push rod 1202 drives the mounting block 1203 to move, and the mounting block 1203 drives the rotating rod 1204 and the rotating gear 1205 to move until the clamping gear 1301 on the rotating rod 1204 is meshed with the limiting gear ring 1303, and the rotating gear 1205 is meshed with the spur rack 1105.
[0053] Close the solenoid valve 1 706, open the solenoid valve 2 1107, so that the clamping block 704 is guaranteed to be in a certain position, and the fine-tuning clamping effect on the workpiece is realized, and the electric push rod 2 1001 is started. The output end of the electric push rod 2 1001 drives the lifting piston 1003 to move in the cylinder 3 1002, so that the gas in the cylinder 3 1002 enters the cylinder 2 1102 through the connecting block 1004 and the conduit 2 1106, so that the pressure in the cylinder 2 1102 increases, so that the gas in the cylinder 2 1102 drives the regulating piston 1103 to move, so that the regulating piston 1103 drives the regulating rod 1104 to move, and the regulating rod 1104 pushes the spur rack 1105 away from the cylinder 2 1102. At this time, the spur rack 1105 is meshed with the rotating gear 1205, and the movement of the spur rack 1105 drives the rotating gear 1205 to rotate clockwise. Since the clamping gear 1301 is meshed with the limiting gear ring 1303, the rotating gear 1205 drives the rotating rod 1204 to rotate, and the rotating rod 1204 drives the clamping gear 1301 and the rotating disk 1302 to rotate, so that the shaft 801 rotates, and the shaft 801 drives the clamping block 802 to rotate clockwise around the axis point of the shaft 801, so that the end of the clamping block 802 is away from the bearing plate 3, and the spring 804 is stretched, so that the distance between the bearing plate 3 and the end of the clamping block 802 is increased, so that the height adjustment of the clamping block 802 is realized, so that the clamping block 802 can adapt to the height of the workpiece;
[0054] Close the electromagnetic valve 1 706, close the electromagnetic valve 2 1107, so that the clamping block 802 is located at a certain height position, put the workpiece on the carrier plate 3, complete the clamping of the sides of the workpiece, at this time, the clamping block 802 is located above the workpiece, start the electric push rod 3 1202, the output end of the electric push rod 3 1202 drives the installation block 1203 to move, the installation block 1203 drives the rotating rod 1204 and the rotating gear 1205 to move, until the clamping gear 1301 on the rotating rod 1204 is separated from the limiting gear ring 1303, and the rotating gear 1205 is separated from the spur rack 1105; at this time, due to the stretching of the spring 804, the spring 804 needs to return to its original state, so that the spring 804 drives the clamping block 802 to move, so that The clamping block 802 rotates downward around the shaft 801 of the shaft 801, so that the clamping block 802 drives the clamping wheel 803 to move until the clamping wheel 803 fits with the top of the workpiece, and at the same time, the electric push rod 901 is started, and the output end of the electric push rod 901 drives the cross plate 902 to move, the cross plate 902 drives the connecting rod 903 to move, the connecting rod 903 drives the connecting frame 904 to move, and the connecting frame 904 drives the lower pressure wheel 905 to move. When the lower pressure wheel 905 contacts the clamping block 802, a force is applied to the clamping block 802, so that the clamping wheel 803 presses the top of the workpiece, thereby clamping the top of the workpieces of different heights, thereby completing the multi-dimensional and all-round fine-tuning of the fixture, and realizing the function of clamping different workpieces;
[0055] The setting of the driving mechanism 4 can provide power to realize the up and down movement of the movable plate 402, thereby moving the slider 502. When the movable plate 402 is driven to move downward, the side clamping and top clamping effect of the clamp on the workpiece are adjusted.
