Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a testing structure with a quick-change magnetic head. Background Technology

[0002] In existing technologies, the detection strips in magnetic head testing equipment are typically directly glued to the head mount. To ensure testing accuracy, the detection strip needs to be in close contact with the sensing surface of the magnetic head. These detection strips are mostly thin titanium alloy plates about 0.1mm thick, which need to be replaced due to wear during use. The existing replacement process is extremely cumbersome: the entire head housing needs to be removed from the equipment, and operators need to manually scrape off the remaining old detection strip from the mount using blades and other tools before re-attaching a new one. This process is not only time-consuming and labor-intensive, resulting in low replacement efficiency, but also easily causes irreversible damage to the delicate magnetic head when scraping off the residual strip and adjusting the head position, leading to product scrapping and increasing maintenance and time costs. Utility Model Content

[0003] Therefore, it is necessary to provide a detection structure that allows for rapid replacement of the magnetic head, in order to solve the problems of the existing technology, such as the cumbersome and inefficient replacement process of the detection plate, the easy damage to the precision magnetic head during the replacement process, and the need to readjust the position after replacement to ensure the fitting accuracy.

[0004] A quick-change magnetic head detection structure includes a magnetic head box, a magnetic head, a mounting base, and a detection plate. The mounting base is fixedly connected to the magnetic head box, the magnetic head is disposed inside the mounting base, a movable seat is disposed between the mounting base and the detection plate, and the detection plate is fixedly disposed on the movable seat. The movable seat is installed on the mounting base through a detachable connection structure, and when the movable seat is installed in place, the detection plate is in close contact with the sensing surface of the magnetic head.

[0005] As a preferred embodiment of the magnetic head replacement detection structure in this invention, the detachable connection structure is a bolt.

[0006] As a preferred embodiment of the magnetic head replacement detection structure in this invention, the movable seat is provided with a pry notch for assisting disassembly.

[0007] As a preferred embodiment of the magnetic head replacement detection structure in this utility model, a foolproof structure is provided between the movable seat and the fixed seat to prevent incorrect installation orientation.

[0008] As a preferred embodiment of the quick-change magnetic head detection structure in this utility model, the foolproof structure includes a foolproof hole disposed on the fixed base and a foolproof pin disposed on the movable base, wherein the foolproof pin and the foolproof hole are adapted to each other.

[0009] As a preferred embodiment of the quick-change magnetic head detection structure in this utility model, the bonding surface of the movable seat with the detection plate is a precision-machined plane.

[0010] As a preferred embodiment of the quick-change magnetic head detection structure in this utility model, the detection plate is a titanium alloy thin plate with a thickness of 0.1mm, which is glued to the movable seat.

[0011] The beneficial effects of this utility model are: This invention optimizes the replacement process of the test strip from "scraping-reattaching-adjusting" to "disassembly-installation" by setting an independent movable base. It eliminates the need to disassemble the magnetic head box and perform delicate and dangerous scraping operations in confined spaces, significantly improving replacement efficiency and reducing equipment downtime. By completely avoiding scraping operations near the precision magnetic head with a blade, the risk of physical damage to the magnetic head during replacement is fundamentally eliminated, protecting core components and reducing maintenance costs. The relative position of the magnetic head and the fixed base is fixed and calibrated at the factory, and the movable base, through precision machining and a foolproof structure, ensures that the installation position is unique and accurate each time. This guarantees that the adhesion accuracy between the test strip and the magnetic head can be automatically restored after each replacement, eliminating the need for manual adjustment and ensuring the stability and reliability of the test results. The foolproof structure effectively prevents product failures caused by incorrect installation direction, lowering the operational threshold and the skill requirements for personnel.

[0020] According to one aspect of this application, embodiments of this application provide a quick-change magnetic head detection structure, which can be referred to in conjunction with the following: Figures 1 to 5 The quick-change magnetic head detection structure includes a magnetic head box 1000, a magnetic head, a fixed base 2000, a detection plate 3000, and a movable base 4000. The fixed base 2000 is fixedly connected to the magnetic head box 1000, and the magnetic head is set inside the fixed base 2000. The movable base 4000 is set between the fixed base 2000 and the detection plate 3000. The detection plate 3000 is fixedly set on the movable base 4000. The movable base 4000 is installed on the fixed base 2000 through a detachable connection structure, and when the movable base 4000 is installed in place, the detection plate 3000 is in close contact with the sensing surface of the magnetic head.

[0021] In this embodiment, the quick-change magnetic head detection structure includes a magnetic head box 1000, a magnetic head, a fixing base 2000, a detection plate 3000, and a movable base 4000. The fixing base 2000 is fixedly installed on the magnetic head box 1000 at a designated position by bolts, and the relative positions of the two remain unchanged. The magnetic head is precisely installed and fixed inside the fixing base 2000. The movable base 4000 is an independent modular component, and its lower surface is a precision-machined plane with a flatness controlled within 0.02mm. The detection plate 3000 is flatly fixed on this plane by high-precision adhesive. During the pasting process, a heavy object can be used to press it to ensure that the adhesive layer is uniform and the detection plate 3000 does not deform. The modular structure replaces the original integrated structure, which greatly improves the replacement efficiency and fundamentally eliminates the risk of physical damage to the magnetic head during the replacement process, protects the core components, and reduces maintenance costs.

[0022] In one embodiment, please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 and Figure 3 The detachable connection structure is a bolt. Bolt holes are provided at corresponding positions on the sides of the fixed seat 2000 and the movable seat 4000. The movable seat 4000 is detachably connected to the fixed seat 2000 by bolts. When the bolts are tightened, the movable seat 4000 is tightly pressed onto the fixed seat 2000. At this time, the detection plate 3000 fixed on the movable seat 4000 and the sensing surface of the magnetic head achieve a preset tight fit, ensuring accurate detection signal.

[0023] In one embodiment, please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 5 The movable seat 4000 is provided with a pry notch 5000 for assisting disassembly. This structure is designed to facilitate the separation of the movable seat 4000 from the fixed seat 2000 during replacement. During replacement, after unscrewing the bolt, simply insert a flathead screwdriver or other thin tool into the pry notch 5000 and gently pry it to use the lever principle to detach the movable seat 4000. The operation is very labor-saving.

[0024] In one embodiment, please refer to [the relevant documentation / reference]. Figures 1 to 5 A foolproof structure is provided between the movable base 4000 and the fixed base 2000 to prevent incorrect installation orientation. This foolproof structure includes a foolproof hole 6000 in the fixed base 2000 and a foolproof pin 7000 in the movable base 4000, which are compatible with each other. The movable base 4000 can only be installed in place when the foolproof pin 7000 is aligned with the foolproof hole 6000, ensuring that the movable base 4000 is always installed in the correct orientation, thus effectively preventing misoperation. The fixed base 2000 and the movable base 4000 also have a locking pin structure for connection and fixation.

[0025] In one embodiment, please refer to [the relevant documentation / reference]. Figure 2 , Figure 3 and Figure 5 The bonding surface between the movable base 4000 and the detection plate 3000 is a precision-machined flat surface to ensure that the detection plate 3000 and the magnetic head sensing surface inside the fixed base 2000 are tightly fitted, so that the whole device can operate normally.

[0026] The replacement process for the quick-change magnetic head detection structure includes the following steps: Disassembly: Use a tool to unscrew the connecting bolts, insert the tool into any of the pry notches 5000, and gently pry to remove the movable seat 4000 along with the worn test piece 3000 as a whole.

[0027] Installation: Take a new movable seat 4000 with the test piece 3000 already pasted on it, align it with the fixed seat 2000 using the foolproof structure, and then push the movable seat 4000 into place.

[0028] Fixing: Install and tighten the bolts to complete the entire replacement process. Thanks to the foolproof structure and precision-machined surface, no adjustments are required after replacement, and the 3000 test piece will immediately achieve optimal contact with the magnetic head.

[0029] 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.

[0030] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
