Description

Technical Field

[0001] This application relates to a backplate inspection device, which belongs to the field of precision manufacturing. Background Technology

[0002] In the field of precision manufacturing, backplate components are core structural parts, and the quality of their threaded holes and the accuracy of their external contours directly determine the assembly reliability and operational safety of the final product. Especially in high-precision fields such as electronics, communications, and aerospace, failure of the backplate threaded holes can lead to fatal quality problems such as loosening of connectors and decreased sealing performance. Therefore, before backplate products are delivered for assembly, their threaded hole condition and external dimensions must be inspected in all dimensions.

[0003] In the backplate processing flow, the magnetic polishing process is a key step in improving surface quality, using high-speed rotating magnetic abrasives to perform micro-cutting on the processing surface. However, this process has an inherent technical contradiction: to ensure polishing efficiency, a large number of tiny magnetic needles (usually less than 0.3 mm in diameter) are required, but these magnetic needles are prone to embedding in the threaded grooves during polishing, causing hidden jamming and rendering the backplate unusable. Utility Model Content

[0004] The purpose of this invention is to provide a backplate detection device that can detect whether there is a magnetic needle-like object inside the threaded hole of the backplate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a backplate detection device, wherein a plurality of threaded holes are provided on the backplate, the backplate detection device comprising:

[0006] A support plate is provided with a plurality of pins, the positions of which correspond to the positions of the threaded holes on the back plate; and

[0007] A plurality of limiting blocks are arranged on the bearing plate, and the plurality of limiting blocks are arranged according to the outer contour dimensions of the back plate.

[0008] Furthermore, the carrier plate is provided with a plurality of mounting holes for mounting the card pins, and the number of mounting holes is greater than the number of card pins.

[0009] Furthermore, an annular groove is formed below the jack, and an elastic block is formed inside the mounting hole, with the elastic block being held in the annular groove.

[0010] Furthermore, the limiting block includes a block body and a locking block protruding downward from the bottom of the block body. The support plate has a plurality of mounting areas for matching and setting the limiting block. Each mounting area has at least two locking slots. The arrangement direction of the at least two locking slots in each mounting area is the same as the direction of the limiting block toward the back plate. The locking slots can match the locking block to fix the limiting block to the support plate.

[0011] Furthermore, a fixing hole is formed on the limiting block, and a locking member is provided on the limiting block. The locking member is inserted into the fixing hole, and the bottom of the locking member abuts against the bearing plate.

[0012] Furthermore, an airfoil groove is formed on the limiting block, and an airfoil block that is inserted into the airfoil groove is protruding from the bearing plate. The airfoil groove and the airfoil block extend in a direction toward the center of the bearing plate.

[0013] Furthermore, the support plate is also provided with a positioning post, the diameter of which is larger than the diameter of the chuck pin, and the back plate is provided with a positioning hole that matches the positioning post.

[0014] Furthermore, the back plate is provided with a number of positioning holes, and the number of positioning pins is less than the number of positioning blocks.

[0015] Furthermore, two of the oppositely arranged sides of the bearing plate are recessed inward to form clearance grooves.

[0016] The beneficial effects of this utility model are as follows: This application limits the placement space of the back plate by limiting the limit block to avoid misalignment between the caliper pin and the threaded hole. During the process of placing the back plate into the placement space, the caliper pin can be inserted into the threaded hole without a magnetic needle. In this way, it can be determined whether there is a magnetic needle in the threaded hole by whether the back plate can be placed into the placement space. The back plate detection device can easily and quickly detect whether there is a magnetic needle in the threaded hole of the back plate.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see Figure 1 The back panel detection device 10 shown in one embodiment of this application is used to detect a back panel (not shown), which has a plurality of threaded holes. The back panel detection device 10 includes a support plate 1 and a plurality of limiting blocks 2. The support plate 1 is provided with a plurality of pins 3, the positions of which correspond to the positions of the threaded holes on the back panel. The plurality of limiting blocks 2 are arranged on the support plate 1, and the plurality of limiting blocks 2 are arranged according to the outer contour dimensions of the back panel.

[0024] This application uses a limiting block 2 to limit the placement space of the back plate, thereby preventing misalignment between the chuck 3 and the threaded hole. During the placement of the back plate into the placement space, the chuck 3 can be inserted into the threaded hole, which does not contain a magnetic needle. Thus, the presence of a magnetic needle in the threaded hole can be determined by whether the back plate can be placed within the placement space. This back plate detection device 10 can easily and quickly detect the presence of a magnetic needle in the threaded hole of the back plate. Furthermore, since the placement space is limited by the limiting block 2, while detecting the magnetic needle, the limiting block 2 can also detect whether the dimensions of the back plate meet the design requirements.

[0025] To facilitate the placement and retrieval of the back panel, two of the oppositely arranged sides of the support plate 1 are recessed inward to form clearance grooves 4.

[0026] The method of using the back panel detection device 10 includes:

[0027] Step A: Adjust the position of the limiting block 2 on the support plate 1 according to the outer contour dimensions of the back panel to define the placement space that can accommodate the back panel.

[0028] Step B: Grab the backplate and place it parallel to the placement space. During placement, align the threaded holes with the pins 3. If any of the threaded holes contain magnetic needles, the pins 3 will not be able to be inserted into the threaded holes, preventing the backplate from being placed into the placement space. If there are no magnetic needles in any of the threaded holes, each pin 3 can be inserted into the corresponding threaded hole, and the backplate can be placed flat in the placement space.

[0029] In some alternative embodiments, a fixing hole 21 is formed on the limiting block 2, and a locking member (not shown) is provided on the limiting block 2. The locking member passes through the fixing hole 21, and the bottom of the locking member abuts against the bearing plate 1. The locking member can be a bolt. Figure 1 In the embodiment shown, the limiting block 2 is locked to the carrier plate 1 by two locking members. Specifically, the limiting block 2 has two fixing holes 21 for inserting the locking members. The two fixing holes 21 can further limit the limiting block 2 and prevent the limiting block 2 from deflecting.

[0030] To prevent the limiting block 2 from deflecting during its movement relative to the support plate 1, and to restrict the lateral movement of the limiting block 2, in one embodiment, a lateral limiting structure is provided between the limiting block and the support plate. Specifically, an airfoil groove is formed at the bottom of the limiting block, and an airfoil block protrudes from the support plate and can be inserted into the airfoil groove. The airfoil groove and the airfoil block extend in a direction toward the center of the support plate 1, and the direction of movement of the airfoil groove and the airfoil block is perpendicular to the side of the support plate. The airfoil groove and the airfoil block combine to form the lateral limiting structure.

[0031] In some alternative embodiments, the limiting block includes a block body and a locking block protruding downward from the bottom of the block body. The support plate has a plurality of mounting areas for matching and mounting the limiting block. Each mounting area has at least two locking slots, and the arrangement direction of the at least two locking slots in each mounting area is the same as the direction of the limiting block toward the back plate, which is oriented toward the side of the support plate. The locking slots can match the locking blocks to fix the limiting block to the support plate.

[0032] The support plate 1 is provided with a plurality of mounting holes for mounting the pins 3. The number of mounting holes is greater than the number of pins 3. The pins 3 are detachably mounted in the mounting holes. In this way, the position of the pins 3 can be adjusted according to the model of the back plate to adapt to different models of back plates. To facilitate the assembly and disassembly of the pins 3, in one embodiment, an annular groove is formed below the pin 3, and an elastic block is formed in the mounting hole. The elastic block is held in the annular groove and can be inserted into the end of the annular groove in a circular shape. The assembly method of the pin 3 and the mounting hole is as follows: When the pin 3 is inserted into the mounting hole, before the annular groove reaches the position of the elastic block, the elastic block is supported by the side wall of the pin 3 and is in a compressed state. When the annular groove reaches the position of the elastic block, the elastic block is no longer supported by the side wall, and the elastic block expands into the annular groove under the drive of its own elastic force, and its end enters the annular groove.

[0033] The support plate 1 is also provided with positioning posts 5, the diameter of which is larger than the diameter of the chuck pin 3. The back plate is provided with positioning holes that match the positioning posts 5. In order to facilitate the adaptation to different models of back plates, the positioning posts 5 can be moved according to different back plates. In one embodiment, the back plate is provided with a number of positioning holes, and the number of positioning posts 5 is less than the number of positioning holes.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
