Description

Technical Field

[0001] The invention relates to a detection device, and in particular to a detection device and a detection method for grinding stone residue after polishing of an aluminum die casting. The device detects grinding stone particles remaining on the surface of the aluminum die casting after grinding stone polishing to meet the cleanliness requirements of the surface of the aluminum die casting. Background Art

[0002] Aluminum die castings present several surface finishing challenges during the manufacturing process, especially in terms of deburring and polishing.

[0003] Aluminum die castings often have complex geometries, including various curved and flat surfaces. Many aluminum die casting designs contain through holes or internal cavities, which increase the complexity of manufacturing and subsequent surface treatment.

[0004] After die casting, aluminum die castings undergo an initial rough trimming process to remove most of the burrs and irregular edges. Despite the rough trimming, burrs may still remain in the corners and through holes of aluminum die castings, which require further processing. In order to remove excess burrs on the surface and improve the surface finish, aluminum die castings need to be polished. The polishing process is as follows: the die casting is placed in a rolling grindstone for polishing to physically remove burrs and smooth the surface. During the polishing process, fine particles of the grindstone may adhere to the surface of the aluminum die casting, which will affect the polishing effect and may damage the surface of the product.

[0005] In order to solve the problem of grindstone adhesion, engineers in this field need to develop a set of targeted grindstone detection devices and detection methods. Summary of the invention

[0017] The preferred technical solution adopted by the present invention to solve the above technical problems is: the horizontal moving assembly includes a base, a guide rail and a slider; the guide rail is laid on the workbench and faces the second side of the positioning block; the slider can move on the guide rail, the base is fixed above the slider, and the second inner cavity profiling member is arranged on one side of the base.

[0018] The preferred technical solution adopted by the present invention to solve the above technical problem is: the pressing assembly is fixed on the base and is located above the second inner cavity profiling member;

[0020] A limiting portion is arranged on the top of the driving rod, a spring is sleeved on the driving rod, and the spring is fixed between the upper bottom plate and the limiting portion.

[0021] The preferred technical solution adopted by the present invention to solve the above-mentioned technical problem is: a damper is provided on the horizontal moving component, and after the horizontal moving component moves toward the second side of the positioning block and contacts the damper, the horizontal moving component slows down and moves. The horizontal moving component is also provided with a limiter, and the limiter is used to limit the movement of the horizontal moving component.

[0022] The preferred technical solution adopted by the present invention to solve the above technical problem is: comprising a controller, the controller is connected with the first sensor, the second sensor, the limiter, the driving mechanism of the horizontal moving component, and the driving mechanism of the pressing component;

[0023] When the controller determines that the first sensor sends a qualified signal indicating that the connection is being made, the controller sends a movement signal to the horizontal movement component;

[0024] When the controller determines that the first sensor sends a non-conforming signal indicating non-bonding, the controller sends a signal to the limiter; the limiter prevents the horizontal moving component from moving toward the positioning block.

[0025] Another technical solution adopted by the present invention to solve the above technical problem is: a method for detecting grindstone residue of aluminum die castings, which is detected by the grindstone residue detection device of aluminum die castings, and includes the following specific steps:

[0027] Step B: the first sensor performs induction detection to determine whether the longitudinal inner cavity of the aluminum die casting is in contact and outputs a detection signal;

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the invention product is usually placed when in use, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. "First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present invention.

[0043] The detection device provided in this embodiment is used to detect an aluminum die casting. The bottom of the first side of the aluminum die casting has a longitudinal inner cavity, and the second side of the aluminum die casting has a transverse inner cavity. After forming, the surface is deburred by a large number of small grinding stones. After the operation is completed, there may be grinding stone residues in the longitudinal inner cavity or the transverse inner cavity, so it needs to be detected.

[0044] like Figure 1 As shown, this embodiment provides a grinding stone residue detection device for aluminum die castings, including a workbench 1 as a support positioning block of the entire detection device, a positioning block 2, a horizontal moving component 30 and a pressing component 20.

[0045] The positioning block 2 is arranged on one side of the workbench 1, and the horizontal moving assembly 30 can move away from and approach the positioning block 2 in a straight line. A third sensor 3 is arranged on the side of the positioning block 2 facing the horizontal moving assembly 30. A first inner cavity profiling member 4 facing upward is arranged on the first side of the positioning block 2, and a first sensor 5 is arranged on the first inner cavity profiling member.

[0046] A second sensor 6 is provided on the second side of the positioning block. A second inner cavity profiling member 7 facing the second side of the positioning block 2 is provided on the horizontal moving assembly 30. An outer profiling member 8 is provided on the second side of the positioning block 2. The outer profiling member 8 includes a recessed portion 81 matching the second side of the aluminum die casting, and protrusions 82 are formed on both sides of the recessed portion 81, and the second sensor 6 is arranged on the protrusion 82.

[0047] The pressing assembly 20 is mounted on the horizontal moving assembly 30, and a lower base plate 9 is mounted on the lower end of the pressing assembly 20. The lower base plate 9 has a lower surface that matches the upper surface of the aluminum die casting.

[0048] When the aluminum die casting is placed on the positioning block 2, the first inner cavity profiling member 4 extends into the longitudinal inner cavity of the aluminum die casting. The first sensor 5 determines whether the longitudinal inner cavity of the aluminum die casting fits the positioning block 2 and whether the first side of the aluminum die casting is flat by contacting the top wall of the longitudinal inner cavity of the aluminum die casting.

[0049] When the second inner cavity profiling member 7 extends into the transverse inner cavity of the aluminum die casting driven by the horizontal moving assembly 30, the third sensor 3 determines whether the transverse inner cavity of the aluminum die casting fits the second inner cavity profiling member 7 by detecting the distance between the horizontal moving assembly 30 and the positioning block 2.

[0050] When the lower bottom plate 9 on the pressing assembly 20 is pressed on the upper surface of the second side of the aluminum die casting, the second sensor 6 determines whether the second side of the aluminum die casting is flat by contacting the lower bottom plate 9.

[0051] Of course, this sensing can be achieved through distance sensing in addition to contact sensing, and the first sensor and the second sensor can be single-point sensors or integrated sensors composed of multiple sensing points.

[0052] The grinding stone residue detection method of aluminum die castings is carried out by using the grinding stone residue detection device of the aluminum die castings, and comprises the following specific steps:

[0053] Step A: The aluminum die casting is placed on the positioning block 2 , and the first inner cavity contour piece 4 on the first side of the positioning block 2 is inserted into the longitudinal inner cavity of the aluminum die casting.

[0054] Step B: The first sensor 5 performs induction detection to determine whether the longitudinal inner cavity of the aluminum die casting is in contact and outputs a detection signal.

[0055] Step C: When the first sensor 5 detects a qualified signal indicating bonding, the horizontal moving assembly 30 moves to the second side of the positioning block 2. However, in the previous step, when the controller determines that the first sensor 5 sends a failed signal indicating non-bonding, the horizontal moving assembly 30 does not move to the second side of the positioning block 2, and determines that there is a grindstone residue in the longitudinal inner cavity, and the detection is terminated.

[0056] Step D: The second inner cavity profiling member 7 on the horizontal moving assembly 30 is inserted into the transverse inner cavity of the aluminum die casting, and the third sensor 3 detects the insertion status of the second inner cavity profiling member 7 .

[0057] Step E: When the third sensor 3 detects that the second inner cavity profiling member 7 is inserted into place, the pressing assembly 20 is pressed down, the spring 24 is compressed, and the lower surface of the lower base plate 9 is close to the upper surface of the aluminum die casting.

[0058] Step F: The second sensor 6 performs induction detection to determine whether the inside and outside of the transverse inner cavity of the aluminum die-casting are in contact with each other and outputs a detection signal. When the second sensor 6 outputs a qualified signal indicating contact, it is determined that there is no grinding stone residue on the aluminum die-casting.

[0059] Through the nesting of the first inner cavity profiling part 4 and the second inner cavity profiling part 7, the first sensor 5 determines the state of the longitudinal inner cavity of the aluminum die-casting, and continues to the next step of detection after passing the test, and then determines the transverse inner cavity and the overall condition of the aluminum die-casting through the second sensor 6 and the third sensor 3, so as to accurately determine whether there is grindstone residue inside the aluminum die-casting through the multi-angle and multi-directional placement of the aluminum die-casting, thereby greatly improving the accuracy of detection.

[0060] It should be noted that the condition of the second inner cavity profiling member 7 of the horizontal moving assembly 30 extending into the transverse inner cavity of the aluminum die casting itself depends on the state of the transverse inner cavity. When a grindstone is left in the transverse inner cavity, the second inner cavity profiling member 7 will not be inserted into place. The additional arrangement of the pressing assembly 20 further strengthens this detection, that is, the longitudinal inner cavity and the transverse inner cavity must be fitted and placed flat to pass the detection, avoiding the omission of the dead angle position detection and further improving the accuracy of the detection.

[0061] The horizontal moving assembly 30 is also provided with a stopper, which is used to limit the movement of the horizontal moving assembly 30. The entire device also includes a controller, which is connected to the first sensor 5, the second sensor 6, the stopper, the driving mechanism of the horizontal moving assembly 30, and the driving mechanism of the pressing assembly 20. When the controller determines that the first sensor 5 sends a qualified signal pointing to the bonding, the controller sends a movement signal to the horizontal moving assembly 30. When the controller determines that the first sensor 5 sends an unqualified signal pointing to the non-bonding, the controller sends a signal to the stopper. The stopper prevents the horizontal moving assembly 30 from moving in the direction of the positioning block 2.

[0062] Through the linkage of the controller, the controller is connected with various sensors and drive mechanisms, which can realize intelligent control of the entire detection process. No human intervention is required. The detection can be started by simply placing the aluminum die-casting on the positioning block 2, which greatly shortens the detection time, improves the detection efficiency, and makes the detection process more stable and reliable.

[0063] like Figure 1 As shown, a positioning column 11 protruding upward is provided at the center of the positioning block, and the positioning column 11 is inserted into the hole groove of the corresponding aluminum die casting. When the aluminum die casting is placed on the positioning block 2 on the workbench 1, the positioning column 11 can be firmly inserted into its hole groove, ensuring that the position of the aluminum die casting is accurate during the working process, making it less likely for the aluminum die casting to shake or move during the detection process, thereby improving the stability and reliability of the detection.

[0064] like Figure 1-2 As shown, the horizontal moving assembly 30 includes a base 31, a guide rail 32 and a slider 33. The guide rail 32 is laid on the workbench 1 and faces the second side of the positioning block. The slider 33 can move on the guide rail 32, the base 31 is fixed above the slider 33, and the second inner cavity profiling member 7 is arranged on one side of the base 31.

[0065] like Figure 3 As shown, the pressing assembly 20 is fixed on the base 31 and is located above the second inner cavity profiling member 7. The pressing assembly 20 includes an upper base plate 21 fixed on the base 31, two guide posts 22 and a driving rod 23. The driving rod 23 passes through the upper base plate 21, and its lower end is connected to the lower base plate 9. The guide posts 22 on both sides pass through the upper base plate 21 and are connected to both sides of the lower base plate 9. A limiting portion Z is provided on the top of the driving rod 23, and a spring 24 is sleeved on the driving rod 23. The spring 24 is fixed between the upper base plate 21 and the limiting portion Z. The design of the spring 24 not only provides the necessary buffer for the pressing process, but also allows the lower base plate 9 to be smoothly reset after the detection is completed, thereby avoiding damage or deformation to the aluminum die casting.

[0066] In addition, a damper 10 is provided on the horizontal moving component 30. After the horizontal moving component 30 moves toward the second side of the positioning block 2 and contacts the damper 10, the horizontal moving component 30 decelerates. By introducing the damper 10, the horizontal moving component 30 can decelerate when approaching the target position, avoiding the overshoot phenomenon caused by inertia, thereby improving the detection accuracy. At the same time, the decelerated movement also reduces the vibration caused by the emergency stop, further improving the stability of the detection.

[0067] In the present application, the first sensor 5 and the second sensor 6 are connected to the first indicator light and the second indicator light, respectively. When in step B, the first sensor 5 detects a qualified signal pointing to the fit, the first indicator light is on, and the display state of the first indicator light remains unchanged as the sensing state of the first sensor 5 remains unchanged. In step D, the lower surface of the lower base plate 9 matches the upper surface of the aluminum die casting. After the second sensor 6 detects a qualified signal pointing to the fit, the second indicator light is on. When the first indicator light and the second indicator light are on at the same time, it is determined that there is no grindstone residue on the aluminum die casting.

[0068] The above is an introduction to the grinding stone residue detection device and detection method provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
