DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-2 A positioning fixture for parts processing in this embodiment includes four support seats 1, and a conveyor platform 2 is fixed on the top of the four support seats 1. The conveyor platform 2 is composed of two sections of isolation belts and a transmission crawler. The transmission crawler is movably connected between the two sections of isolation belts. The bottoms of the two sections of isolation belts are fixed to the support seats 1. The setting of the isolation belt is beneficial to the safety of the fixture and on-site personnel, and plays an effective role in the stable operation of the fixture.

[0022] The top of the two telescopic rods 5 on the same side is fixed with a connecting plate 6. The telescopic rod 5 is composed of a sleeve rod and an inner rod. The top of the sleeve rod is fixed to the connecting plate 6, and the bottom of the sleeve rod is fixed to the supporting plate 4. The inner rod passes through the sleeve rod and is movably connected with the sleeve rod. Through the fixing effect of the connecting plate 6 and the telescopic rod 5, the connecting plate 6 moves in the direction of the telescopic rod 5. The telescopic rod 5 limits the movement of the clamp, thereby improving the stability of the clamp operation. The front and rear sides of the bottom of the connecting plate 6 are fixed with an outer shell 7. The outer shell 7 acts as a partition, which is beneficial to reducing the impact of the clamp device on on-site personnel and improving the safety of the clamp and on-site personnel. The interior of the outer shell 7 is provided with a positioning component 8 that passes through the outer shell 7 and is used to position square parts.

[0023] It should also be noted that a connecting rod 9 is movably connected to the top of the connecting plate 6, and a connecting shaft is fixed to the top of the connecting plate 6. The two ends of the connecting rod 9 are respectively sleeved on the outer surfaces of the connecting shaft and the round shaft. A movable block 10 is hinged between the two connecting rods 9. This design utilizes the movable block 10 to cooperate with the connecting rods 9 on the left and right sides. One cylinder 11 can drive the entire clamp device, reducing the use of power devices, simplifying the clamp structure, reducing the manufacturing cost of the clamp, and improving the convenience of the clamp. A cylinder 11 is fixed to the top of the support plate 4, and a sleeve block 12 is fixed to the movable shaft of the cylinder 11. A fixed column 13 is fixed to the top of the left connecting plate 6, and the sleeve block 12 is sleeved on the outer surface of the fixed column 13. The sleeve cooperation between the sleeve block 12 and the fixed column 13 is beneficial to the stability of the device during operation and improves the stability of the clamp.

[0024] Furthermore, the movable block 10 is composed of a rotating base and circular shafts on the left and right sides. A movable shaft is fixed at the axis of the rotating base, the movable shaft is movably connected to the support plate 4, and the top of the rotating base is fixed to the two circular shafts.

[0025] In this embodiment, a movable block 10 and a connecting rod 9 are provided, and the connecting rod 9 and the connecting plate 6 cooperate with each other. The cylinder 11 drives the connecting plate 6 on the left to displace, and the connecting plates 6 on both sides are relatively moved under the transmission of force, and finally the positioning components 8 on both sides effectively clamp the parts. At the same time, the positioning components 8 can self-adjust the fitting position between the parts, and the positioning effect is good, which is conducive to real-time adjustment of the positioning state and improves the positioning efficiency.

[0026] See also Figure 3In order to quickly position the parts, the positioning assembly 8 in this embodiment includes a limit plate 802 fixed to the inner bottom wall of the shell 7, and a movable column 801 extending to the outside of the shell 7 is movably connected to the axis of the limit plate 802, and a guide plate 803 is fixed to the bottom of the movable column 801.

[0027] It should also be added that the guide plate 803 is composed of an active plate and a driven plate, and the angle between the active plate and the driven plate is ninety degrees. This design is conducive to the fitting and positioning of the guide plate 803 to the square parts. The active plate and the driven plate are both fixed to the movable column 801. Pulleys 804 are fixed at both ends of the bottom of the guide plate 803. Pulleys 804 are conducive to reducing friction with the parts, reducing wear on the parts, and speeding up the positioning speed of the square parts. Pulley 804 is composed of a connecting column and a clamping disk. The axis of the clamping disk is movably connected to the connecting column. The connecting column passes through the guide plate 803 and is fixed to the guide plate 803.

[0028] It can be understood that by setting the guide plate 803 to ninety degrees, it is beneficial to the stability of the clamp's positioning of the square part. Setting the structure of the pulley 804 is beneficial to increasing the positioning rate of the clamp, speeding up the positioning speed of the clamp, and facilitating the convenient positioning of the clamp.

[0029] In this embodiment, the transmission track on the conveyor platform 2 moves forward, driving the parts to translate from back to front, and the parts contact the pulley 804 on the rear side. Through the transmission force of the transmission track and the contact force between the structures, the angle of the guide plate 803 together with the movable column 801 is adjusted, driving the pulley 804 to adjust the clamping surface in contact with the parts, thereby effectively positioning the parts, which is conducive to real-time adjustment of the positioning state, improving positioning efficiency, and thus improving working results.

[0030] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0031] The working principle of the above embodiment is:

[0032] After starting the conveyor 2, the square part moves to the clamp position along the transmission crawler. At this time, the cylinder 11 begins to shrink, and the sleeve block 12 fixed to the top of the cylinder 11 begins to move. The fixing column 13 fixed to the sleeve block 12 drives the connecting plate 6 fixed thereto to start moving. Under the fixing action of the telescopic rod 5, the connecting plate 6 will move along the direction of the telescopic rod 5, and the shell 7 fixed to the bottom of the left connecting plate 6 drives the positioning assembly 8 fixed thereto to move toward the middle. The connecting rod 9 on the left side will adjust the angle at the same time, and drive the movable block 10 to rotate at the same time. The other connecting rod 9 on the movable block 10 will drive the connecting plate 6, shell 7 and positioning assembly 8 on the other side to move closer to the middle under the action of traction, until the positioning assemblies on both sides are Part 8 contacts the transmitted part and realizes positioning. At this time, the pulley 804 on the rear side of each group of positioning components 8, due to its placement state, preferentially contacts the left and right sides of the square part. Since the guide plate 803 is fixed to the movable column 801, and the movable column 801 can rotate in the limit plate 802, the pulley 804 on the front side of each group of positioning components 8 will adjust its position under the action of force, and the pulley 804 on the front side will fit to the front and back sides of the square part, so that the pulley 804 fits the four sides of the square part, thereby positioning the entire square part, and then the transmission track can be closed. The overall structure is simple, and the positioning state can be adjusted in real time, which is beneficial to improving the positioning effect during processing and improving the positioning efficiency.
