DETAILED DESCRIPTION

[0021] Example

[0022] refer to Figures 1 to 4 The present embodiment describes a special positioning device for die casting processing, comprising a placing table 1, a groove 2 is provided at the upper end of the placing table 1, a vacuum suction cup 3 is fixedly connected inside the groove 2, suction components 4 are fixedly connected on both sides of the placing table 1, a support plate 5 is installed on one side of the vacuum suction cup 3 in the groove 2, which can support the middle of the die casting and disperse the pressure on the vacuum suction cup 3, a soft pad 7 is fixedly connected to the upper end of the support plate 5, the soft pad 7 is made of rubber to prevent the die casting from sliding on the support plate 5, a reset mechanism 6 is provided on the lower side of the support plate 5, and the upper end of the placing table 1 is located on the support plate Both sides of 5 are slidably connected with reinforcement plates 11, which are slightly higher than the upper plane of the placement table 1. Even if they come into contact with the die-casting, they will not cover too much area and will not affect the processing of the die-casting. When the suction component 4 is working, the air inside the vacuum suction cup 3 is extracted to form a low-pressure area. At this time, the atmospheric pressure outside the die-casting will be greater than the pressure inside the vacuum suction cup 3, thereby generating an inward suction force, so that the die-casting fits tightly on the vacuum suction cup 3. Most of the structure of the die-casting is exposed to the outside and is not covered, which is beneficial for operators to process the die-casting, reduces the difficulty of operation, and avoids errors in the processing process.

[0023] refer to Figure 1The suction assembly 4 includes a vacuum pump 41, which is fixedly connected to both sides of the placement table 1.

The side is magnetically connected to the electromagnet 632; by opening a first mounting groove 62 in the groove 2, a spring 61 is fixed in the first mounting groove 62, and the spring 61 is connected to the support plate 5. When the die-casting is placed on the support plate 5, the spring 61 is slowly deformed. At this time, the support plate 5 moves into the groove 2 and is flush with the vacuum suction cup 3, which can effectively prevent the die-casting from falling instantly and causing a large impact on the vacuum suction cup 3. When the die-casting is completely placed, the connecting rod 631 enters the first rod sleeve 633 and contacts the electromagnet 632. The power supply 634 supplies power to the electromagnet 632, so that the electromagnet 632 absorbs the connecting rod 631, thereby fixing the spring 61 and making it temporarily unable to deform, thereby avoiding micro-movement of the spring 61 that affects the die-casting processing and ensuring the stable placement of the die-casting.

[0025] refer to Figure 2 A second mounting groove 8 is provided on both sides of the first mounting groove 62 in the groove 2, a fixing rod 9 is fixedly connected inside the second mounting groove 8, a second rod sleeve 10 is slidably connected to one side of the fixing rod 9, and one end of the second rod sleeve 10 is fixedly connected to one end of the support plate 5; by means of the second mounting groove 8 in the groove 2, the fixing rod 9 is connected in the second mounting groove 8, the second rod sleeve 10 is fixed under the support plate 5 and slides on the fixing rod 9, the support plate 5 is guided to move in the groove 2, the deviation causing the die-casting to be placed unsteadily is avoided, and the stability of the die-casting during placement is improved.

By fixing the slide rod 15 in the slide groove 12, the reinforcement plate 11 can slide more stably in the slide groove 12.

[0027] Principle and advantages of use: Place the die casting on the support plate 5, and the spring 61 under the support plate 5 is deformed in the first mounting groove 62 under the force, so that the die casting on the support plate 5 moves slowly downward to prevent the die casting from falling instantly and contacting the vacuum suction cup 3 to cause a large impact. The connecting rod 631 under the support plate 5 is inserted into the first rod sleeve 633 and adsorbed by the electromagnet 632 to prevent the spring 61 from restoring its elasticity and causing the die casting to shake. The vacuum pump 41 generates negative pressure when it works, and the hose 42 is connected to multiple gas collecting pipes 43, which are connected to the air guide pipe 44, and the air guide pipe 44 is connected to the vacuum suction cup 3, so that The vacuum suction cup 3 generates suction, and multiple vacuum suction cups 3 cooperate with each other to position the die-casting, so that the die-casting can be fixed on the placement table 1. Since the bottom of the die-casting is adsorbed, most of the structure of the die-casting is exposed and not covered, which is beneficial for operators to process the die-casting, reduces the difficulty of operation, and avoids errors in the processing process. When the placement position of the die-casting needs to be reinforced, the handle 14 is turned to drive the screw 13 to rotate, so that the reinforcement plate 11 slides in the slide groove 12, and the two reinforcement plates 11 are in contact and clamped with the die-casting, which can further position the die-casting.
