Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a testing fixture for the aperture of an ultra-thin soft steel sheet. Background Technology

[0002] Ultra-thin soft steel sheets have a small thickness and high flexibility. To meet product requirements, several small holes need to be etched on the ultra-thin soft steel sheets. The diameter of the holes is in the micrometer range. To ensure product quality, the diameter of the holes on the ultra-thin soft steel sheets needs to be detected. The detection fixtures in the existing technology are usually complex in structure and have high equipment costs. Utility Model Content

[0003] The purpose of this utility model is to provide a fixture for detecting the aperture of ultra-thin soft steel sheets, which aims to solve the technical problems in the prior art.

[0004] To achieve the above objectives, this utility model provides an ultra-thin soft steel sheet aperture detection fixture, including a base and a fixed module and a movable module disposed on the top of the base. A push-pull force gauge is fixedly connected to the top of the fixed module, and a detection wire is installed on the detection shaft of the push-pull force gauge. The detection wire extends towards the movable module. The movable module includes a guide rail disposed on the base and a slide block that slides with the guide rail. The top of the slide block is provided with a fixing groove and at least two magnetic pressure blocks. The fixing groove is used to place the soft steel sheet, and the two magnetic pressure blocks are used to fix the two ends of the soft steel sheet respectively. The top of the slide block is also provided with a clearance groove to achieve clearance with the detection wire. The extension direction of the clearance groove is consistent with the extension direction of the guide rail.

[0005] Preferably, the fixing module includes a clamping base and two clamping plates, the two clamping plates being detachably connected to the top of the clamping base, and a clamping position being formed between the two clamping plates for clamping the push-pull force gauge.

[0006] Preferably, the top of the clamp is provided with a movable groove, and the bottom of the two clamps are detachably connected to the movable groove.

[0007] Preferably, the inner wall of the movable groove is provided with a flexible part, and the clamping plate is provided with screws that are threadedly connected to the flexible part.

[0008] Preferably, there are two fixing slots, which are symmetrically arranged on both sides of the clearance slot. One end of each fixing slot is connected to the inside of the clearance slot, and the other end is connected to the outside.

[0009] Preferably, the guide rail has two guide grooves symmetrically arranged on its two side walls, and the slide block has a guide part that is slidably connected to each of the guide grooves.

[0010] The above-mentioned technical solutions in the ultra-thin soft steel sheet aperture detection fixture provided in this embodiment of the utility model have at least one of the following technical effects:

[0011] In use, a soft steel sheet is placed in a fixed groove, and two magnetic blocks are magnetically connected to the corresponding positions at both ends of the soft steel sheet, thus fixing the soft steel sheet by pressing the two magnetic blocks against both ends. The detection wire installed on the push-pull force gauge passes through the small hole on the soft steel sheet, and the sliding block is driven to move along the guide rail by the moving module. At this time, if the diameter of the small hole on the soft steel sheet is too small, the reading on the push-pull force gauge will be too large, and if the diameter of the small hole on the soft steel sheet is too large, the reading on the push-pull force gauge will be too small, thus achieving the detection effect of the small hole on the soft steel sheet. The structure is simple and the accuracy is high. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0022] In one embodiment of this utility model, such as Figures 1-4 As shown, an ultra-thin soft steel sheet aperture detection fixture is provided, including a base 1 and a fixed module 2 and a movable module 3 disposed on the top of the base 1. A push-pull force gauge 20 is fixedly connected to the top of the fixed module 2. A detection wire 201 is installed on the detection shaft of the push-pull force gauge 20. The detection wire 201 extends towards the movable module 3. The movable module 3 includes a guide rail 31 disposed on the base 1 and a slide block 32 that slides with the guide rail 31. A mounting seat is slidably connected to the top of the slide block 32. The sliding direction of the mounting seat is perpendicular to the sliding direction of the slide block 32. The top surface of the mounting seat is provided with a fixing groove 321 and at least two magnetic pressure blocks 322. The fixing groove 321 is used to place the soft steel sheet 10, and the two magnetic pressure blocks 322 are respectively used to fix the two ends of the soft steel sheet 10.

[0023] Furthermore, the fixing module 2 includes a clamping base 21 and two clamping plates 22. The two clamping plates 22 are detachably connected to the top of the clamping base 21, and a clamping position 221 is formed between the two clamping plates 22 for clamping the push-pull force gauge 20. The top of the clamping base 21 is provided with a movable groove 211, and the bottom of the two clamping plates 22 is detachably connected to the movable groove 211. The inner wall of the movable groove 211 is provided with a flexible part 212, and the clamping plates 22 are provided with screws 222 that are threadedly connected to the flexible part 212. Specifically, when installing the push-pull force gauge 20, the push-pull force gauge 20 is installed on the top of the clamp 21, with the detection end of the push-pull force gauge 20 facing the direction of the moving module 3. The extension direction of the movable groove 211 is perpendicular to the orientation of the detection end of the push-pull force gauge 20. The two clamping plates 22 are placed on the top of the movable groove 211, with the two clamping plates 22 spanning across the top of the movable groove 211 and respectively attached to both sides of the push-pull force gauge 20. Screws 222 are inserted into the screw holes of the two clamping plates 22 respectively and threadedly connected to the flexible part 212 in the movable groove 211 to fix the two clamping plates 22 and achieve the clamping effect of the push-pull force gauge 20. By setting the movable groove 211, the position of the push-pull force gauge 20 can be adjusted within the length range of the movable groove 211, achieving a multi-position adjustment effect.

[0024] Furthermore, there are two fixing slots 321, which are symmetrically arranged on both sides of the clearance slot 323. One end of the fixing slot 321 is connected to the inside of the clearance slot 323, and the other end is connected to the outside. Specifically, after installing the push-pull force gauge 20 into the fixing module 2 and the soft steel sheet 10 into the fixing groove 321, the detection wire 201 is installed on the detection end of the push-pull force gauge 20. The detection wire 201 is then pulled toward the soft steel sheet 10 and passes through the small hole on the soft steel sheet 10 for detection. By setting the clearance groove 323, the detection wire 201 can extend into the clearance groove 323 after passing through the small hole on the soft steel sheet 10, thereby increasing the length of the detection wire 201 after it is inserted into the small hole on the soft steel sheet 10. This increases the length of the detection wire 201 and the small hole detection cooperation, achieving a more accurate detection effect. In addition, since the soft steel sheet 10 is relatively soft, in order to prevent the detection wire 201 from pulling the soft steel sheet 10 and causing displacement during detection, the position of the magnetic pressure block 322 can be moved closer to both sides of the clearance groove 323, thereby increasing the rigidity of the soft steel sheet 10 located above the clearance groove 323 and further improving the detection effect.

[0025] Furthermore, the guide rail 31 has two guide grooves 311 symmetrically arranged on its two side walls, and the slide block 32 is provided with a guide part 324 that is slidably connected to each of the guide grooves 311.

[0026] Working principle: In use, the soft steel sheet 10 is placed in the fixing groove 321 and magnetically connected to the top surface of the slide block 32 at the corresponding positions of the two ends of the soft steel sheet 10 by two magnetic pressure blocks 322, so that the two magnetic pressure blocks 322 press against the two ends of the soft steel sheet 10 to fix the soft steel sheet 10. The detection wire 201 installed in the push-pull force gauge 20 passes through the small hole on the soft steel sheet 10. The slide block 32 is driven to move along the guide rail 31 by the moving module 3. At this time, if the diameter of the small hole on the soft steel sheet 10 is too small, the reading on the push-pull force gauge 20 will be too large, and if the diameter of the small hole on the soft steel sheet 10 is too large, the reading on the push-pull force gauge 20 will be too small, thus realizing the detection effect of the small hole on the soft steel sheet 10.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
