Description

Technical Field

[0001] The utility model relates to the technical field of casting detection, in particular to a casting hole detection device. Background Art

[0002] Castings refer to metal parts or products manufactured by casting processes, which are usually used to manufacture automotive parts and mechanical equipment. The holes on the castings are one of the key parts of the entire casting. Testing them can ensure that the quality of the castings meets the design requirements. If the size, shape or position of the holes does not meet the standards, it will cause problems in the assembly of the castings, affecting the performance and service life of the overall product. In the prior art, the inspector will hold a cylindrical rod for inspection, which is cylindrical and has a diameter equivalent to the standard hole diameter. The cylindrical rod will be inserted into multiple holes to be inspected on the castings in sequence. When the cylindrical rod can pass through the hole to be inspected, it means that the hole is qualified. When the cylindrical rod cannot pass through the hole to be inspected, it means that the hole is unqualified. At this time, the inspector needs to record the position of the unqualified hole so that the unqualified hole can be processed later. By analogy, until all the holes on the castings are inspected, the castings will proceed to the next step of processing. This method of inspection by inspectors holding cylindrical rods is inefficient and is not conducive to improving the inspection efficiency of casting holes. Utility Model Content

[0043] Rack 700;

[0044] A positioning assembly 500, the positioning assembly 500 is arranged on the frame 700, and the positioning assembly 500 is used to position the casting;

[0045] A fixing assembly 600, which is disposed on the frame 700 and is used to fix the casting on the positioning assembly 500;

[0046] A first linear drive assembly 100 and a plurality of first columnar rods 120, wherein the first linear drive assembly 100 is disposed on the frame 700, and the plurality of first columnar rods 120 are parallel to the up-down direction, and the first linear drive assembly 100 can drive the plurality of first columnar rods 120 to descend, so that the plurality of first columnar rods 120 can respectively pass through a plurality of through holes on the outer edge of the casting;

[0047] Multiple first pressure sensors and multiple first indicator lights 710, the multiple first indicator lights 710 are all arranged on the frame 700, the multiple first pressure sensors are respectively used to detect the pressure exerted on the multiple first columnar rods 120, and the multiple first pressure sensors are respectively electrically connected to the multiple first indicator lights 710, so that when any first pressure sensor detects that the first columnar rod 120 is subjected to pressure, the first indicator light 710 electrically connected to any first pressure sensor can light up.

[0048] It is understandable that the inspector can place the casting to be inspected on the positioning assembly 500 on the frame 700, and the positioning assembly 500 plays a positioning role on the casting, and then the fixing assembly 600 is started, and the fixing assembly 600 can fix the casting on the positioning assembly 500 to prevent the casting from shaking during the inspection. Then the first linear drive assembly 100 is started, and the first linear drive assembly 100 drives the multiple first columnar rods 120 to descend, so that the multiple first columnar rods 120 can pass through the multiple through holes on the outer edge of the casting respectively. The multiple first pressure sensors are respectively used to detect the pressure on the multiple first columnar rods 120, and the multiple first pressure sensors are respectively electrically connected to the multiple first indicator lights 710, that is, the multiple first columnar rods 120 are respectively set in a one-to-one correspondence with the multiple first indicator lights 710, that is, the multiple first indicator lights 710 are respectively set in a one-to-one correspondence with the multiple through holes on the outer edge of the casting. When any of the first columnar rods 120 cannot pass through the corresponding through hole on the outer edge of the casting, the first columnar rod 120 will be stuck on the hole wall of the through hole, so that the first columnar rod 120 will be under pressure. At this time, the first pressure sensor used to detect the pressure of the first columnar rod 120 will detect the pressure of the first columnar rod 120 and trigger, thereby making the first indicator light 710 electrically connected to the first pressure sensor light up. By observing that a certain first indicator light 710 is lit, the inspector can quickly know that a certain through hole on the outer edge of the casting corresponding to the currently lit first indicator light 710 is unqualified.

[0049] When any of the first columnar rods 120 can pass through the corresponding through hole on the outer edge of the casting, the first columnar rod 120 will not be subjected to additional pressure, and the first pressure sensor used to detect the pressure of the first columnar rod 120 will not be triggered, so that the first indicator light 710 electrically connected to the first pressure sensor will not light up. When the inspector observes that a certain first indicator light 710 is not lit, it can be quickly known that a certain through hole on the outer edge of the casting corresponding to the currently lit first indicator light 710 is qualified. The casting hole detection equipment can simultaneously detect whether the sizes of multiple through holes on the outer edge of the casting are qualified, which is conducive to improving the detection efficiency of the casting holes. On the other hand, the inspector can quickly know which of the multiple through holes on the outer edge of the casting corresponding to the multiple first indicator lights 710 are qualified and which are unqualified by observing whether the multiple first indicator lights 710 are lit, which is also conducive to improving the detection efficiency of the casting holes.

[0050] In the present invention, a plurality of first marks are provided on the area corresponding to the plurality of first indicator lights 710 on the rack 700, and the plurality of first marks are respectively provided in one-to-one correspondence with the plurality of first indicator lights 710, that is, the plurality of first marks are respectively corresponding to the plurality of through holes on the outer edge of the casting. The plurality of first marks are respectively used to identify the positions of the plurality of through holes on the outer edge of the casting, so that when a certain first indicator light 710 is on, the inspector can observe the first mark corresponding to the lit first indicator light 710 and know that the through hole on the outer edge of the casting corresponding to the first mark is unqualified, so that the inspector can quickly record the position of the unqualified through hole so as to process the unqualified through hole later.

[0051] refer to Figure 1 and Figure 2 The positioning assembly 500 includes a plurality of positioning columns 510, which are parallel to the up-down direction, the lower ends of which are connected to the frame 700, and the upper ends of which are used to abut against the casting. In the present invention, the upper ends of the plurality of positioning columns 510 can be inserted into the grooves on the casting, so that the upper ends of the plurality of positioning columns 510 can position the casting.

The output end of the lifting drive 610 is connected to the pressing plate 620. The lifting drive 610 can drive the pressing plate 620 to descend so that the pressing plate 620 presses against the casting on the positioning assembly 500. It can be understood that after the inspection personnel place the casting on the positioning assembly 500, the lifting drive 610 drives the pressing plate 620 to descend close to the casting on the positioning assembly 500, and then the pressing plate 620 presses against the casting on the positioning assembly 500, thereby fixing the casting on the positioning assembly 500.

The cylinder bodies of the plurality of first cylinders 110 are all disposed on the support plate 630. The plurality of first columnar rods 120 are respectively inserted into the plurality of first avoidance holes. The upper ends of the plurality of first columnar rods 120 are respectively connected to the piston rods of the plurality of first cylinders 110. The plurality of first cylinders 110 are respectively used to drive the plurality of first columnar rods 120 to move in the up and down directions. It can be understood that after the inspector places the casting on the positioning assembly 500, the lifting drive 610 drives the pressing plate 620 to descend close to the casting on the positioning assembly 500, and the pressing plate 620 drives the support plate 630, the plurality of first cylinders 110 and the plurality of first columnar rods 120 to descend. When the pressing plate 620 is pressed against the casting on the positioning assembly 500, the multiple first cylinders 110 respectively drive the multiple first columnar rods 120 to descend, so that the multiple first columnar rods 120 can detect the multiple through holes on the outer edge of the corresponding casting. In the present utility model, after the casting is placed on the positioning assembly 500, the multiple first avoidance holes on the pressing plate 620 correspond to the multiple through holes on the outer edge of the casting. As an embodiment of the present utility model, the fixing assembly 600 also includes a plurality of pressing blocks (not shown in the figure), and the multiple pressing blocks are all arranged on the lower surface of the pressing plate 620, and the multiple pressing blocks can extend into the casting cavity and abut against the casting.

[0054] refer to Figures 4 to 6 The casting hole detection equipment also includes a second linear drive component 200, a plurality of second columnar rods 220, a plurality of second pressure sensors and a plurality of second indicator lights 720.

[0055] It is understandable that after the inspector places the casting to be inspected on the positioning assembly 500 on the rack 700, the fixing assembly 600 is started to fix the casting on the positioning assembly 500. Then the first linear drive assembly 100 and the second linear drive assembly 200 are started at the same time, and the second linear drive assembly 200 drives the plurality of second columnar rods 220 to rise, so that the plurality of second columnar rods 220 can respectively pass through the plurality of through holes on the bottom wall of the casting cavity. The plurality of second pressure sensors are respectively used to detect the pressure exerted on the plurality of second columnar rods 220, and the plurality of second pressure sensors are respectively electrically connected to the plurality of second indicator lights 720, that is, the plurality of second columnar rods 220 are respectively arranged in a one-to-one correspondence with the plurality of second indicator lights 720, that is, the plurality of second indicator lights 720 are respectively arranged in a one-to-one correspondence with the plurality of through holes on the bottom wall of the casting cavity. When any of the second columnar rods 220 cannot pass through the corresponding through hole on the outer edge of the casting, the second pressure sensor for detecting the pressure of the second columnar rod 220 will detect the pressure of the second columnar rod 220 and trigger, so that the second indicator light 720 electrically connected to the second pressure sensor will light up. By observing that a certain second indicator light 720 lights up, the inspector can quickly know that a certain through hole on the bottom wall of the casting cavity corresponding to the currently lit second indicator light 720 is unqualified. Similarly, when any of the second columnar rods 220 can pass through the corresponding through hole on the bottom wall of the casting cavity, the second indicator light 720 corresponding to the second columnar rod 220 will not light up. When the inspector observes that a certain second indicator light 720 is not lit, it can be quickly known that a certain through hole on the bottom wall of the casting cavity corresponding to the currently lit second indicator light 720 is qualified.
