Description

Technical Field

[0001] This utility model belongs to the field of precision parts testing technology, and in particular relates to a testing device for precision parts. Background Technology

[0002] Precision parts refer to parts with small tolerances in size, shape, and position, and high surface quality requirements. They are core basic components of high-end manufacturing industries, characterized by micron-level machining accuracy, complex geometric structures, and strict performance requirements. In order to ensure the quality of precision parts, the hardness of precision parts is usually sampled and tested, so testing equipment is required.

[0003] Most current hardness testing devices use Rockwell hardness testers. However, most existing Rockwell hardness testers lack protective mechanisms. In the hardness testing of precision parts, most of the precision parts are exposed. If the precision parts break during the test, fragments will fly everywhere, which is quite dangerous. Therefore, a testing device for precision parts is provided. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] In specific implementation, such as Figures 1-5 As shown, this utility model provides a technical solution: a testing device for precision parts, including a body 1, the body 1 being a Rockwell hardness tester as the main body; a positioning component 5, the positioning component 5 being disposed on the inner wall of the bottom surface of the body 1, used to fix the precision parts when the testing needle 4 tests the precision parts; and a protective component 6, the protective component 6 being disposed on the outer surface of the positioning component 5, used to shield the precision parts during the testing process; wherein, the protective component 6 includes a protective cover 61, the inner surface of the protective cover 61 being provided with a plurality of sliding grooves 62, a support spring 63 being fixedly installed on the inner wall of the bottom surface of the sliding grooves 62, a slider 64 being fixedly installed at one end of the support spring 63, the outer surface of the slider 64 being slidably connected to the inner wall of the sliding grooves 62, the protective cover 61 being annular and made of transparent material.

[0036] When the upper part of the protective cover 61 contacts the lower surface of the disk 2, a sealed space is formed inside the protective cover 61. As the support plate 58 continues to move upward, the support plate 58 will drive the slider 64 to move in the slide groove 62. At this time, the support spring 63 is in a stretched state. After the precision parts are inspected, the support plate 58 descends and the protective cover 61 loses its compression. Under the action of the support spring 63, the protective cover returns to its original position.

[0037] like Figures 2-4 As shown, the positioning component 5 includes a fixing ring 51. The lower surface of the fixing ring 51 is fixedly connected to the inner wall of the bottom surface of the machine body 1. A groove is provided on the inner wall of the bottom surface of the machine body 1. The fixing ring 51 corresponds to the groove. A threaded sleeve 52 is rotatably installed on the upper surface of the fixing ring 51. A threaded post 53 is threadedly installed on the inner surface of the threaded sleeve 52. One end of the threaded post 53 passes through the interior of the fixing ring 51 and extends into the groove. The other end of the threaded post 53 extends above the threaded sleeve 52 and is fixedly installed on a fixing cylinder 55. A through groove is provided on the inner wall of the threaded post 53. A limiting rod 54 is slidably installed on the threaded post 53 through the through groove. One end of the limiting rod 54 is fixedly connected to the inner wall of the bottom surface of the groove. The limiting rod 54 is square and plays a limiting role when the threaded post 53 moves up and down. A plurality of positioning holes 59 are provided on the outer surface of the fixing cylinder 55, and the positioning holes 59 surround the outer surface of the fixing cylinder 55. The inner wall of the top surface of the fixing cylinder 55 A rotating sleeve 56 is rotatably mounted on the upper part of the rotating sleeve 56. An installation hole 510 is provided on the inner surface of the rotating sleeve 56. A positioning spring 511 is fixedly mounted on the inner wall of the installation hole 510. A positioning bead 512 is fixedly mounted on one end of the positioning spring 511. The positioning bead 512 is compatible with the positioning hole 59. A scroll plate 57 is fixedly mounted on the upper surface of the rotating sleeve 56. Both the scroll plate 57 and the rotating sleeve 56 are provided with slots. A connecting block is fixedly mounted on the upper surface of the fixed cylinder 55. The block extends through the slot to the top of the volute 57 and is fixedly installed with a support plate 58. The upper surface of the support plate 58 is provided with a stroke groove, and a moving block 514 is slidably installed on the inner wall of the stroke groove. The lower surface of the moving block 514 is provided with a slot that matches the volute 57. A flexible clamp 513 is fixedly installed on the upper surface of the moving block 514. The inner wall of the protective cover 61 is in contact with the outer surface of the support plate 58, and the side wall of the slider 64 is fixedly connected to the outer surface of the support plate 58.

[0038] The precision part to be tested is placed on the support plate 58, and then the rotating sleeve 56 drives the scroll plate 57 to rotate. As the scroll plate 57 rotates, the moving block 514 will be displaced in the stroke groove under the action of the slot and the scroll plate 57, thereby driving the flexible clamp 513 to clamp the precision part. After the precision part is clamped stably, the positioning bead 512 is embedded in the positioning hole 59 under the action of the positioning spring 511, thereby fixing the scroll plate 57 by fixing the rotating sleeve 56, thus firmly clamping the precision part. Then the threaded sleeve 52 is rotated above the fixing ring 51. Under the action of the thread, the threaded column 53 will move upward under the limit of the limiting rod 54, thereby driving the fixing cylinder 55 to move upward synchronously. As the fixing cylinder 55 moves upward, it will drive the precision part to move upward synchronously. During the upward movement of the precision part, the detection needle 4 detects the hardness of the precision part.

[0039] like Figure 1 A disk 2 is fixedly installed on the inner wall of the top surface of the body 1 shown. A magnetic block 3 is magnetically installed on the lower surface of the disk 2. A detection needle 4 is fixedly installed on the lower surface of the magnetic block 3. A wire is fixedly installed at the input end of the detection needle 4. One end of the wire passes through the disk 2 and extends into the body 1 and is connected to the body 1.

[0040] Remove the magnetic block 3 from the disk 2, align one end of the detection needle 4 with the position of the precision part to be detected, and then fix the magnetic block 3 on the disk 2 to fix the detection needle 4. The detection needle 4 is electrically connected to the internal structure of the machine body 1 through the wire, which is the prior art in this field, and will not be described in detail.

[0041] Working principle: The precision part to be inspected is placed on the support plate 58. Then, the rotating sleeve 56 drives the scroll plate 57 to rotate. As the scroll plate 57 rotates, the moving block 514 will be displaced within the stroke groove under the action of the slot and the scroll plate 57, thereby driving the flexible clamp 513 to clamp the precision part. After the precision part is clamped stably, the positioning bead 512 is inserted into the positioning hole 59 under the action of the positioning spring 511, thereby fixing the scroll plate 57 by fixing the rotating sleeve 56, thus firmly clamping the precision part. Then, the magnetic block 3 is removed from the disk 2. After aligning one end of the detection needle 4 with the position of the precision part to be inspected, the magnetic block 3 is fixed on the disk 2, thereby fixing the detection needle 4. Then, the screw... The threaded sleeve 52 rotates above the fixed ring 51. Under the action of the thread, the threaded post 53 moves upward under the limit of the limiting rod 54, thereby driving the fixed cylinder 55 to move upward synchronously. As the fixed cylinder 55 moves upward, it drives the precision parts to move upward synchronously. During the upward movement of the precision parts, the detection needle 4 detects the hardness of the precision parts. When the upper part of the protective cover 61 contacts the lower surface of the disk 2, a sealed space is formed inside the protective cover 61. As the support plate 58 continues to move upward, the support plate 58 drives the slider 64 to move in the slide groove 62. At this time, the support spring 63 is in a stretched state. After the precision parts are detected, the support plate 58 descends and the protective cover 61 loses its compression. Under the action of the support spring 63, the protective cover returns to its original position.

[0042] 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.
