Description

Technical Field

[0001] This utility model relates to the field of mechanical testing, specifically to a thread testing device for screw components. Background Technology

[0002] Standard parts refer to commonly used components whose structure, dimensions, drawing methods, markings, and other aspects have been completely standardized and are produced by specialized factories, such as threaded parts, keys, pins, and rolling bearings. Currently, after the processing and production of screw parts, it is impossible to determine with the naked eye whether the threads produced meet the quality standards. The principle of screw thread inspection mainly relies on measuring the geometric parameters of the thread (such as thread angle, pitch, and pitch diameter) to determine whether it conforms to the standard. Therefore, a specialized thread inspection device is required. A search revealed a screw standard part production inspection device disclosed in application number CN202020888648.8, which describes a device including a base plate with an inspection mechanism on top of the base plate; the inspection mechanism includes a second tactile switch, an inspection box on top of the second tactile switch, and a first tactile switch fixedly installed at the bottom of the inspection box. The device has a horizontal plate at the top, with multiple second springs fixed at the bottom of the horizontal plate. A push plate is located at the top of the horizontal plate, and an electric push rod is fixed to one side of the push plate. The electric push rod is fixedly connected to the side wall of the testing box. Multiple first springs are fixed at the top of the testing box, with a top plate fixed to one end of each first spring. A buzzer is fixed at the top of the testing box. The weight of the screw is detected by using the testing box and a second tactile switch to select screws that are too heavy or too light, thus achieving the purpose of detecting the screw weight. However, the above description has the following defects in actual use: the device cannot detect the threads machined on the surface of the screw. Also, due to differences in manufacturing requirements, the thread lengths on the surface of the screw are different, resulting in a lack of positioning assistance function in the thread detection process. Therefore, it is necessary to design a more practical thread detection device for screws. Utility Model Content

[0021] Please see Figures 1-3 A thread testing device for screw components includes: a testing base 1, guide rods 11 on both sides of the top of the testing base 1, fixing rings 12 on the surface of the two guide rods 11, and a rotating groove 13 in the middle of the top of the testing base 1.

[0022] Please see Figure 2 The detection component 2 includes a forward and reverse motor 21 installed at the bottom of the inner wall of the rotating groove 13. The output shaft of the forward and reverse motor 21 is fixedly connected to the detection turntable 22. The top of the detection turntable 22 is provided with a support plate frame 23. The top of the support plate frame 23 is provided with a detection sleeve 24. The inner wall of the detection sleeve 24 is designed to correspond to the thread on the surface of the screw. The surfaces of the two guide rods 11 are slidably connected to the moving plate 25. Guide sleeves 26 are provided on both sides of the top of the moving plate 25. An installation plate 27 is provided in the middle of the top of the moving plate 25. A support sleeve 28 is rotatably connected to the middle of the top of the installation plate 27. The auxiliary block on the surface of the screw on the inner wall of the support sleeve 28 is engaged.

[0023] In practical use: The screw to be tested is inserted into the support sleeve 28, so that the bottom end contacts the inner wall of the test sleeve 24. The forward and reverse motor 21 drives the test turntable 22 to rotate. The test turntable 22, together with the support plate frame 23, drives the test sleeve 24 to rotate. The inner wall of the test sleeve 24 drives the screw to perform thread testing. The screw, together with the auxiliary block, drives the support sleeve 28 to move. The support sleeve 28, together with the mounting plate 27, drives the moving plate 25 to move on the surface of the two guide rods 11. The moving plate 25 drives the two guide sleeves 26 to move and limits their movement. At the same time, together with the test base 1, the two springs 16 are compressed to maintain the stability of the testing process. While the test sleeve 24 is rotating, together with the data processor in the test base 1, the test data is displayed on the surface of the display screen 18, thus facilitating the thread testing of the screw surface.

[0024] Please see Figure 3The positioning auxiliary component 3 includes two vertical rails 31 installed on the top two sides of the detection base 1. The top of each of the two vertical rails 31 is connected to the top of the two guide rods 11 through a connecting rod 32. The surfaces of the two vertical rails 31 on opposite sides are provided with scales 33. The surfaces of the two scales 33 are slidably connected to the positioning pointers 29 provided at both ends of the moving plate 25.

[0025] In practical use: the bottom of the two vertical rails 31 are fixed to the detection base 1 with two sets of limit pins 34. The top of the two vertical rails 31 has two connecting rods 32 inserted and engaged with the top of the two guide rods 11, and the two are fixed with two limit nuts 15. When the moving plate 25 moves, it drives the two positioning pointers 29 to slide on the surface of the two scales 33, thereby recording the detection length of the thread on the surface of the screw according to the scale of the moving position, which plays a positioning auxiliary role. At the same time, after the detection is completed and the rotation is completed, the elasticity of the two springs 16 can drive the moving plate 25 to reset, avoiding the safety hazards caused by the disengagement process.

[0026] Please see Figure 2 The top edge of the support plate 23 is provided with several snap-fit ​​connectors 210.

[0028] Please see Figure 2 A through groove 213 is provided in the middle of the top of the movable plate 25. A slot 214 is provided in the middle of both sides of the inner wall of the through groove 213. The inner walls of the two slots 214 are engaged with the slot blocks 215 provided on both sides of the mounting plate 27. The two slot blocks 215 are threadedly fixed to the movable plate 25 by connecting pins 216.

[0029] In practical use: the locking blocks 215 on both sides of the mounting plate 27 are engaged with the inner walls of the two slots 214, and the two locking blocks 215 are fixed to the moving plate 25 with the two connecting pins 216, so as to facilitate the installation and disassembly of the mounting plate 27, thereby adapting to the disassembly and assembly of screw parts of different specifications.

[0030] Please see Figure 3 Both fixing rings 12 have rubber washers 14 at their bottoms, and the diameter of the two rubber washers 14 is the same as the diameter of the two guide sleeves 26.

[0031] In practical use: the two rubber washers 14 have the same diameter as the two guide sleeves 26, which facilitates a buffering effect during reset.

[0032] Please see Figure 3 The surfaces at the bottom of the two vertical rails 31 are threaded to the edges of the top two sides of the detection base 1 via limit pins 34.

[0033] In practical use: the bottom of the two vertical rails 31 are fitted with two sets of limit pins 34 and fixed to the detection base 1, which facilitates the installation and disassembly of the positioning auxiliary structure and the detection base 1.

[0034] Please see Figure 3 Each of the two guide rods 11 has a limiting nut 15 on the top surface and a spring 16 on the bottom surface of each of the two guide rods 11.

[0035] In practical use: the two limit nuts 15 can limit and fix the two connecting rods 32 and the two guide rods 11, and the springs 16 on the bottom surface of the two guide rods 11 can ensure the stability of the detection movement process.

[0036] Please see Figure 3 An indicator light 17 is provided on one side corner of the top of the detection base 1, and a display screen 18 and a control panel 19 are provided on one side of the detection base 1.

[0038] In use, the screw to be tested is inserted into the support sleeve 28, so that its bottom end contacts the inner wall of the testing sleeve 24. The forward and reverse motor 21 drives the testing turntable 22 to rotate. The testing turntable 22, together with the support plate 23, drives the testing sleeve 24 to rotate. The inner wall of the testing sleeve 24 drives the screw thread to be tested. The screw, together with the auxiliary block, drives the support sleeve 28 to move. The support sleeve 28, together with the mounting plate 27, drives the moving plate 25 to move on the surface of the two guide rods 11. The moving plate 25 drives the two guide sleeves 26 to move and limits their movement. At the same time, the testing base 1 corresponds to the two springs 16. The extrusion process maintains stability during the testing process. As the testing sleeve 24 rotates, it works with the data processor inside the testing base 1 to display the testing data on the surface of the display screen 18, thus facilitating the thread testing of the screw component surface. When the moving plate 25 moves, it drives the two positioning pointers 29 to slide on the surfaces of the two scales 33, thereby recording the testing length of the screw component surface thread according to the scale of the moving position, which plays a role in positioning assistance. At the same time, after the test is completed and the plate rotates back, the elasticity of the two springs 16 can drive the moving plate 25 to reset, avoiding safety hazards caused by the disengagement process.
