Description

Technical Field

[0001] This utility model belongs to the field of raw ear production testing, specifically, it relates to a strength tester for raw ear production testing. Background Technology

[0002] Spring bars are steel bars that connect the watch strap to the watch dial. 90% of watches are secured by spring bars. Spring bars are a professional term for watch parts.

[0003] The strength of spring bars determines whether a watch strap will fall off when worn. Therefore, spring bars need to be sampled and tested after production to determine whether their strength meets the standards. Existing testing equipment cannot test multiple spring bars at the same time. Furthermore, when spring bars are deformed under stress, the internal spring components can easily cause the movable end to pop out, which can easily cause eye injury to the observer. In view of this, this utility model is proposed. Utility Model Content

The workbench is located above the base. A C-shaped frame is fixed at the top center of the workbench. Drive seats are symmetrically fixed at the bottom center of the C-shaped frame. The drive ends of the two drive seats are fixed to an alignment plate. The alignment plate is driven to move back and forth by the drive ends. A slide rail for multiple sliders to slide and connect is fixed at the upper end of the alignment plate. Each slider is fixed to the slide rail by a limiting bolt at its front end. A positioning post is fixed at the top of each slider. A groove for fixing the new ear is opened on the opposite face of every two adjacent positioning posts. A limiting hole for fixing the telescopic end of the new ear is provided on the side of the groove.

[0007] A tension plate is fixed in the middle of the C-shaped frame. The tension plate is installed at the top of the middle of the C-shaped frame via an electric push rod. Multiple transmission rods are evenly distributed at the bottom of the tension plate. A C-shaped block is fixed at the bottom of each transmission rod. The tension plate is located above and behind the alignment plate. Guide blocks for horizontal movement of the two frames are fixed on opposite sides of the bottom of the middle of the C-shaped frame. A tempered glass plate is fixed in the middle of each frame.

[0008] Optionally, the center of the C-shaped frame is symmetrically fixed with guide rods for installing guide sleeves, and the two guide sleeves are respectively fixed on both sides of the tension plate.

[0009] Optionally, a pressure block is movably connected to the lower center of the C-shaped block. Each pressure block has a clearance hole on its side for the imitation rod to pass through. The imitation rod is fixedly installed inside the C-shaped block. The bottom of the pressure block is provided with an abutment end for abutting the pressure sensor. The pressure sensor is connected to the display via a wire. The display is fixedly installed at the front end of the transmission rod.

[0010] Optionally, each of the simulated deflection rods is fitted with a return spring, and the two ends of the return spring abut against the inside of the pressure block and the C-shaped block, respectively. Rubber rings are fixed on the upper side of both ends of the pressure block.

[0011] Optionally, each of the frames has a guide groove at the upper center for mounting guide posts, and the guide posts are fixedly mounted in the middle of the steering frame. Each of the frames has equally spaced locking teeth for transmission gears at the top. The transmission gears are rotatably connected to the first frame via a shaft, and the first frame is fixedly mounted on the side of the shaped frame. The upper end of the transmission gear is meshed with a drive gear, which is fixedly sleeved on the outside of the output shaft of the drive motor.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] This invention uses multiple positioning posts to fix multiple spring ears for testing at once. After the spring ears are positioned, the extension end of the electric push rod drives the tension plate to rise, so that the C-shaped blocks at the bottom of multiple transmission rods apply tension to the spring ears corresponding to their positions simultaneously. In order to help users understand the tension value of the spring ears, the tension value of the spring ears is obtained through pressure sensors and then displayed on the display for the reference of the testing personnel. In the case that the internal springs may pop out after the spring ears are deformed by force, which may cause injury to the eyes of the testing personnel, this invention uses a sliding closed frame to protect the eyes of the testing personnel with tempered glass. Even if the deformed parts of the spring ears pop out in an emergency, they will be blocked by the tempered glass plate.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figures 1 to 8 This utility model provides a technical solution: a strength tester for testing new ear production, including a base 1, a workbench 2, a shaped frame 3, an electric push rod 14, a pressure sensor 24, and a tempered glass plate 19. The workbench 2 is provided above the base 1. The shaped frame 3 is fixed at the top center of the workbench 2. The drive seats 4 are symmetrically fixed at the bottom center of the shaped frame 3. The drive ends 5 of the two drive seats 4 are fixed to the alignment plate 6. The alignment plate 6 is driven to move back and forth through the drive ends 5. The upper end of the alignment plate 6 is fixed with a slide rail 8 for multiple sliders 7 to slide and connect. Each slider 7 is fixed to the slide rail 8 through a limit bolt 9 at the front end. The top of each slider 7 is fixed with a positioning post 10. A groove 11 for fixing the new ear is opened on the opposite face of every two adjacent positioning posts 10. A limit hole 12 for fixing the telescopic end of the new ear is provided on the side of the groove 11.

[0031] A tension plate 13 is fixed in the middle of the C-shaped frame 3. The tension plate 13 is installed at the top middle of the C-shaped frame 3 via an electric push rod 14. Multiple transmission rods 15 are evenly distributed at the bottom of the tension plate 13. A C-shaped block 16 is fixed to the bottom of each transmission rod 15. The tension plate 13 is located above and behind the alignment plate 6. Guide blocks 18 for horizontal movement of two frames 17 are fixed opposite each other at the front of the bottom middle of the C-shaped frame 3. A tempered glass plate 19 is fixed in the middle of each frame 17. Considering existing... The current testing equipment cannot simultaneously test multiple spring ears, resulting in low testing efficiency. This invention addresses this issue by using multiple positioning posts 10 to fix multiple spring ears at once. After the spring ears are positioned, the extension end of the electric push rod 14 drives the tension plate 13 to rise, causing the C-shaped blocks 16 at the bottom of multiple transmission rods 15 to simultaneously apply tension to the corresponding spring ears. Furthermore, to facilitate user understanding of the tension value borne by the spring ears, a pressure sensor 24 is used to obtain the tension value. The tension applied to the spring ear is then displayed on the monitor 26 for the inspector's reference. In cases where the internal spring mechanism can easily cause the movable end to pop out after the spring ear deforms under stress, potentially injuring the inspector's eyes, this invention uses a sliding closed frame 17 to protect the inspector's eyes with tempered glass. Even if the spring ear deforms and pops out in an emergency, the tempered glass plate 19 will prevent it from doing so. During inspection, the spring ear is first placed between two positioning posts 10. Then, the telescopic end of the spring ear is fixed by contacting the interior of the limiting hole 12. The driving end 5 of the drive seat 4 moves the alignment plate 6 backward, causing the spring ear to stop in the middle area of ​​the C-block 16. At this point, the telescopic rod of the electric push rod 14 retracts, causing the tension plate 13 to rise and contact the surface of the spring ear from the pressure block 22. The contact end 25 of the pressure block 22 presses down on the pressure sensor 24. The pressure sensor 24 then acquires the tension value and displays it on the monitor 26.

[0032] Among them, the middle part of the C-shaped frame 3 is symmetrically fixed with guide rods 21 for the installation of guide sleeves 20. The two guide sleeves 20 are respectively fixed on both sides of the tension plate 13. By setting the guide rods 21, it is ensured that the tension plate 13 will not shift its position when it is displaced.

[0033] Among them, a pressure block 22 is movably connected to the lower middle part of the C-shaped block 16. Each pressure block 22 has a clearance hole on its side end for the imitation rod 23 to pass through. The imitation rod 23 is fixedly installed inside the C-shaped block 16. The bottom of the pressure block 22 is provided with a contact end 25 for contacting the pressure sensor 24. The pressure sensor 24 is connected to the display 26 through a wire. The display 26 is fixedly installed at the front end of the transmission rod 15. By setting the pressure sensor 24 to apply the pulling force to the spring ear to the C-shaped block 16, it plays a detection role, which makes it convenient for the tester to know the pulling force applied to the spring ear when viewed from the side.

[0034] Each of the anti-deviation rods 23 is fitted with a return spring 27, and the two ends of the return spring 27 abut against the inside of the pressure block 22 and the C-shaped block 16, respectively. Rubber rings 28 are fixed on the upper side of both ends of the pressure block 22. By setting the anti-deviation rods 23, the pressure block 22 will not shift in position, which can ensure that the contact end 25 accurately abuts against the pressure measuring end of the pressure sensor 24.

[0035] Each frame 17 has a guide groove at the top center for the installation of guide posts 29, and the guide posts 29 are fixedly installed in the middle of the direction frame. Each frame 17 has equidistant locking teeth 31 fixed at the top for the transmission gear 30 to drive. The transmission gear 30 is rotatably connected to the first frame 32 via a shaft, and the first frame 32 is fixedly installed on the side of the C-shaped frame 3. The upper end of the transmission gear 30 is meshed with a drive gear 33, which is fixedly sleeved on the outside of the output shaft of the drive motor 35. The drive motor 35 is fixedly installed on the second frame 34 via a housing, and the second frame 34 is fixed on the top of the C-shaped frame. The drive motor 35 drives the drive gear 33 to rotate. When the drive gear 33 rotates, it drives the driven gear to rotate. The driven gear, through meshing with the locking teeth 31, drives the two frames 17 to perform horizontal displacement, thereby completing the opening and closing of the tempered glass plate 19. When closed, it forms a protective barrier without affecting the inspection personnel's penetration of the spring ear.

[0036] Among them, the bottom of the workbench 2 is symmetrically fixed with fixing plates 36. The lower side of the opposite surface of the two fixing plates 36 is provided with T-shaped grooves for the two ends of the collection drawer 37 to be inserted. By setting the collection drawer 37, the spring ears that cannot be used normally after deformation are collected, which facilitates centralized processing in the later stage.

[0037] The base 1 has self-locking casters 38 installed at the four corners of its bottom, and support columns 39 are fixed at the four corners of its upper end. Each support column 39 has an electric telescopic rod 40 fixed inside, and each electric telescopic rod 40 has a support block 41 fixed at its end. The support block 41 is fixedly installed at the bottom of the workbench 2. The self-locking casters 38 facilitate the user's later movement of the equipment. The electric telescopic rod 40 and the support block 41 are used to adjust the height of the workbench 2. The height of the workbench 2 can be changed according to the operating comfort of the testing personnel.

[0038] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
