Technical Field

[0001] This utility model relates to the field of jigs, specifically a jig for locking screws on a picture frame. Background Technology

[0002] During the screw fastening process of electronic glasses frames, the small size and simple structure of the frames make it difficult to align the screws with the screw holes in the semi-automatic screw fastening process, which greatly reduces the efficiency of screw fastening the frames.

[0003] Therefore, it is necessary to provide a fixture for locking screws in picture frames. Summary of the Invention

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown, the frame screw-locking fixture provided in the embodiment of this application includes a base 1, a support 2 disposed on the base 1, a side-pressing mechanism 3 disposed on the base 1 for laterally clamping the frame on the support 2, and a screw guide mechanism 4 disposed on the base 1. The screw guide mechanism 4 includes a mounting block 41 fixedly disposed on the base 1 and a cover plate 42 hinged to the mounting block 41. The lower end face of the cover plate 42 is provided with a contoured surface that contacts the support 2 and the product. The cover plate 42 is provided with a guide through hole 401, which corresponds to the screw hole of the screw to be locked on the frame.

[0018] In actual use, open the cover plate 42, place the product on the support 2, then press the frame onto the support 2 by the side pressing mechanism 3, then close the cover plate 42, insert the screw through the guide hole 401, and then use a screwdriver to pass through the guide hole 401 to lock the screw to the frame.

[0019] In the above design, the screw guide mechanism 4 can improve the efficiency of screw and screw hole alignment and fastening.

[0020] Specifically: the guide hole 401 includes a vertical hole and a tapered hole communicating with the vertical hole. The diameter of the vertical hole is not greater than the length of the screw to be fastened. The vertical hole is concentric with the screw hole of the screw to be fastened in the frame.

[0021] In actual use, the screw passes through the tapered hole and then through the vertical hole to correspond with the screw hole.

[0022] In the above design, the structural design and specific implementation of the guide hole 401 can effectively guide the screw quickly and improve the fastening efficiency.

[0023] Specifically: such as Figure 2 and Figure 3 As shown, the support base 2 is provided with an abutting surface that abuts against the outside of the frame. The side pressing mechanism 3 includes a pushing component 31 provided on the base 1 and a pressing component 32 symmetrically provided on the base 1 along the pushing component 31. The pushing component 31 is used to drive the pressing component 32 to press the frame. The axis of symmetry of the pushing component 31 when the frame is placed on the support base 2 coincides with the axis of symmetry of the frame.

[0024] In actual use, the frame is placed on the support 2 so that the mirror surface and the contact surface are facing each other. Then, the two pressing components 32 are driven by the pushing component 31 to move synchronously to the pre-pressing position until the pressing component 32 is pushed to the predetermined position to press the frame and then stops. The pressing component 32 is continuously pressed, so that the pressing component 32 continuously presses the frame.

[0025] In the above design, the structural design and specific implementation of the support seat 2 and the side pressure mechanism 3 can effectively apply equal pressure to the two side pressure positions of the frame at the same time, ensuring that the frame will not be damaged due to compression.

[0026] Specifically: such as Figure 2 and Figure 3As shown, the pushing assembly 31 includes a first linear guide rail 311 arranged on the base 1 along the Y-axis direction, a push block 312 slidably arranged on the first linear guide rail 311, a fixing block 313 fixedly arranged on the base 1, and a quick clamp 314 arranged on the fixing block 313 for driving the push block 312. The push block 312 has two inclined surfaces symmetrical about the linear guide rail on both sides, and the inclined surfaces are slidably connected to the clamping assembly 32.

[0027] In actual use, the push block 312 is driven by the quick clamp 314 to slide along the first linear guide rail 311, so that the push block 312 pushes the clamping assembly 32 to move towards one side of the frame through the inclined surface.

[0028] In the above design, the structural design and specific implementation of the pushing component 31 enable the pressing component 32 to be pushed synchronously and then kept locked by the quick clamp 314.

[0029] Specifically: such as Figure 3 As shown, the clamping assembly 32 includes a second linear guide rail 321 mounted on the base 1, a slider 322 slidably mounted on the second linear guide rail 321, a positioning block 323 fixedly mounted on the base 1 and located on the side of the second linear guide rail 321 away from the pushing assembly 31, a first compression spring 324 whose two ends respectively abut against the positioning block 323 and the slider 322, a plurality of guide posts 325 slidably mounted on the slider 322 and parallel to the second linear guide rail 321, a pressure block 326 fixedly connected to the ends of the plurality of guide posts 325, and a second compression spring 327 sleeved on the guide posts 325 and whose two ends abut against the pressure block 326 and the slider 322 respectively.

[0030] In actual use, when the clamping assembly 32 is pushed by the pushing assembly 31, the first compression spring 324 is compressed under force. After the pressure block 326 contacts the frame, the second compression spring 327 undergoes compression deformation as the slider 322 moves relative to the guide post 325. As the pushing assembly 31 disengages from the clamping assembly 32, the first compression spring 324 and the second compression spring 327 gradually return to their original positions. The elastic force of the first compression spring 324 drives the slider 322 to a position where the pressure block 326 will not interfere with the loading and unloading of materials.

[0031] In the above design, the structural design and specific implementation of the clamping component 32 can effectively achieve automatic reset and effective buffering when clamping the frame.

[0032] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
