Embodiment 1

[0046] like figure 1 As shown, this embodiment provides an automated processing technology for a new energy vehicle brake caliper, which includes the following steps:

[0047] S1. Automatic core unloading: remove the sand core of the new energy vehicle brake caliper from the double-layer sand core table by the sand core robot and place it on the sand core mold of the gravity casting machine; among them, the specifications and models of the sand core robot It is R-2000IC / 165; the double-layer sand core table includes a double-layer shuttle table, and each layer of the shuttle table is placed with eight mold sand cores. The new energy vehicle brake caliper is a double-cylinder caliper;

[0048] S2. Pouring: A pouring robot equipped with a seven-axis pouring arm and a liquid taking and pouring mechanism is used to scoop the aluminum alloy melt from the crucible holding furnace, and pour it into the sand core mold of the gravity casting machine to obtain a semi-finished product; ...

Embodiment 2

[0058] like Figure 2-5 As shown, this embodiment provides a liquid-taking and pouring mechanism, which is used for liquid level detection and liquid-taking and pouring of aluminum alloy melt after being assembled with a seven-axis pouring arm of a pouring robot, including an assembly head 1, a sampling box 2 and a sampling Cover 3, the assembly head 1 is fixed on the top of the sampling box 2, the sampling cover 3 is covered on the outside of the sampling box 2 and is fastened by bolts 16, the sampling box 2 is rotated and connected with a ladle mechanism near the bottom, and the sampling box 2 The inner cavity is provided with two detection pipes 4 extending out of the bottom of the sampling box 2 .

[0059] The ladle mechanism includes a biaxial motor 5, a casing 6, a rotary shaft 7 and a stainless steel ladle 8. The biaxial motor 5 is located in the inner cavity of the sampling box 2 near the bottom, and the motor shaft of the biaxial motor 5 extends toward both sides and ...

Embodiment 3

[0063] like Figure 6-7 As shown in the figure, this embodiment provides a sand hammer, which is used for high-frequency hammering during doffing to separate the sand core from the surface of the brake caliper cooling semi-finished product, crack it into pieces, and remove it by collapsing, including a frame 17 and a hammer box 18 and the waste sand collection chamber 19, the hammer box 18 and the waste sand collection chamber 19 are respectively arranged at the top and bottom of the frame 17, the hammer box 18 is provided with a soundproof room 20 inside, and the outside of the soundproof room 20 is equipped with a soundproof door 21 . The hammering box 18 is provided with a high-frequency hammering mechanism and an oscillating positioning mechanism.

[0064] Through the high-frequency hammering of the high-frequency hammering mechanism and the positioning oscillation of the oscillating positioning mechanism, the sand core and the surface of the brake caliper cooling semi-fi...

Abstract

The invention discloses an automatic machining process for brake calipers of a new energy automobile, and relates to the technical field of automobile part machining. The automatic machining technology comprises the steps of automatic core setting, pouring, piece taking, cooling, defect detection, doffing, cutting, deburring and piece discharging and outputting, automatic core setting is completed through a sand core placing robot, liquid taking and pouring are completed through a pouring robot, and clamping and transferring in the cooling, defect detection, doffing, cutting, deburring and piece discharging and outputting processes are completed through a post-treatment robot. In the pouring step, a seven-axis pouring arm and a liquid taking and pouring mechanism are arranged, so that the liquid taking angle is conveniently adjusted in time or molten aluminum alloy is supplemented in time; in the doffing step, high-frequency hammering is matched with swinging oscillation, so that the sand core and the surface of a cooled semi-finished product are rapidly separated, cracked and collapsed, the sand core is not prone to remaining on the surface of the cooled semi-finished product, and the sand core removal rate reaches 95% or above; the automatic machining process is high in machining efficiency and high in sand core removal rate, and the quality of finished products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to an automatic processing technology of a new energy vehicle brake caliper. Background technique [0002] Automobile brake calipers are castings that require compactness. In practical applications, defects such as shrinkage cavities and porosity should not occur. It is necessary to comprehensively analyze various influencing factors on the basis of actual conditions, optimize the casting process and cast automobile brakes efficiently at the same time. The caliper controls the tensile strength, yield strength, elongation, etc. within the specified range, so as to maximize the function of the brake caliper and improve the safety, reliability and economy of automobile operation. The improvement of the casting process of automobile brake calipers can start from the two aspects of gating system and alloy composition. On the basis of analyzing the improvement results, the c...
