Description

Technical Field

[0001] The utility model relates to the field of low-pressure casting, in particular to a piece-taking manipulator for low-pressure casting of a wheel hub. Background Art

[0002] A low-pressure casting machine is a device used for metal casting, usually to produce high-quality castings. During the low-pressure casting process, metal is usually injected into a mold in liquid form, which is usually located in a sealed container. Then, by applying moderate gas pressure, usually nitrogen or an inert gas, the metal is forced into the mold and maintained in its shape until solidified. Compared with high-pressure casting, low-pressure casting usually requires less equipment investment and it is easier to control bubbles and pores during the molding process, so it can produce higher-quality castings, especially automotive wheels, which are mostly molded by low-pressure casting.

[0003] After the wheel hub is formed by casting, it is necessary to take the formed wheel hub out of the mold. Generally, a picking robot or manual picking tools are used to pick it out. The problem with manual labor is that it requires labor costs, low automation efficiency, and low flexibility of the automatic robot for picking up parts. The traditional picking robot is a fixed-position picking and placing robot with poor height and rotation flexibility. In addition, the position of the picking robot is relatively fixed and cannot be flexibly changed according to the usage scenario. During casting, it will block the use of the low-pressure casting machine. At the same time, the temperature of the wheel hub is high after it is taken out of the mold. After the picking robot clamps the wheel hub, it needs to be placed in a receiving tray for cooling. The storage process can only be entered after the temperature drops. During this process, the process is slow and requires waiting, which lengthens the production cycle and reduces production efficiency. Summary of the invention

A picking robot assembly 8 is arranged below the rotating motor 7, and the picking robot assembly 8 includes a clamping claw 8a, a central seat 8b and a connecting arm 8c, and a heat dissipation assembly 9 is arranged on the central seat 8b.

[0027] See also Figure 1 The base 3 is arranged on the auxiliary pulley 2d, and a limit plate 10 is arranged between the auxiliary pulley 2d and the fixed base 1. The transverse motor 2a is arranged on the base 3. The rotating shaft of the transverse motor 2a passes through the base 3 and extends to the bottom of the base 3. A transverse driving wheel 2e is arranged at one end of the rotating shaft of the transverse motor 2a. The transverse driving wheel 2e is meshed with the transverse rack 2b. The base 3 is the main mobile supporting plate. When the picking robot assembly 8 is driven, the transverse motor 2a drives the transverse driving wheel 2e to rotate, and the transverse rack 2b is meshed and driven to move laterally, while the transverse crawlers 2c and the auxiliary pulleys 2d on both sides limit and assist the movement of the base 3.

[0028] See also Figure 3The longitudinal rack 4b is fixedly connected to the connecting spindle 5, and the connecting spindle 5 is in a rectangular square tube shape. A longitudinal driving wheel 4e is provided on the rotating shaft of the longitudinal motor 4a, and the longitudinal driving wheel 4e is meshed with the longitudinal rack 4b. The longitudinal slide assembly 4 and the transverse slide assembly 2 have basically the same structure and mode, and adopt the same method, that is, the longitudinal motor 4d drives the longitudinal driving wheel 4e to rotate and mesh with the longitudinal rack 4b to produce longitudinal displacement. Different from the transverse displacement, the Y-axis position of the base 3 is limited by the fixed base 1, so that the base 3 does not produce longitudinal movement. Therefore, when the longitudinal motor 4a rotates, the connecting spindle 5 is displaced in the Y-axis direction through the gear and rack transmission, thereby realizing the Y-axis movement of the picking robot 8.

[0029] Slide blocks 5a are provided on both sides of the connecting spindle 5, and the slide blocks 5a are engaged with the limiting slide rails 4d. The slide blocks 5a and the limiting slide rails 4d are used to assist the Y-axis displacement and limit the position.

[0030] See also Figure 5 The heat dissipation component 9 includes a cover plate 9a, a heat dissipation fan 9b, a filter 9c and a connecting frame 9d. The connecting frame 9d is connected to the central seat 8b by bolts. The heat dissipation component is an air cooling system, which is supported and fixed by the connecting frame 9d and is located above the clamping claw 8a. When the picking robot assembly 8 clamps the wheel hub, air cooling begins to be performed to blow away part of the heat for heat dissipation, and a filter 9c is placed above the air inlet of the heat dissipation fan 9b to filter dust in the air.

[0031] See also Figure 5 A circular cavity 9e is opened in the cover plate 9a, a cooling fan 9b is arranged in the circular cavity 9e, a placement seat 9f is provided above the cooling fan 9b, a filter 9c is arranged above the placement seat 9f, and the placement seat 9f is a circle of circular platform on the inner wall of the circular cavity 9e, the filter 9c can be placed on it, so that the filter 9c is easy to disassemble and clean.

[0032] Track grooves are provided on one side of the transverse track 2c and the longitudinal track 4c.

[0033] The specific working principle is as follows: this device is used in conjunction with a low-pressure casting machine and is mostly used for wheel hub injection molding. After being fixed at a suitable position of the low-pressure casting machine by a fixed base 1, when the wheel hub is demoulded after casting is completed, the XY axis position is adjusted through the transverse slide assembly 2 and the longitudinal slide assembly 4, and the reinforced connecting frame 6 is used to connect and rotate the rotating motor 7 to take out the parts. After taking out the parts, the heat dissipation assembly 9 performs air cooling to take away part of the heat to achieve rapid cooling and then discharge the material to complete the demoulding and clamping work.
