[0005] The above-mentioned clamp cannot be adaptively adjusted according to the size of the eyeglass frame, which makes it very inconvenient for users to use it when processing eyeglass frames of different sizes. Utility Model Content

[0006] The utility model aims to solve or at least alleviate the problem that the existing clamp cannot be adaptively adjusted according to the size of the eyeglass frame, which causes great inconvenience to the user when processing eyeglass frames of different sizes.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] By adopting the above technical scheme, when using, the user first slides the adjustment seats provided at both ends of the beam along the length direction of the beam according to the size of the glasses frame to be processed, adjusts the two adjustment seats to appropriate positions, and then screws the limit bolts into the adjusting seats to squeeze the beam to increase the friction between the adjustment seats and the beam, thereby fixing the adjustment seats and the beam relatively. At this time, after opening the fixing clamp, the two sides of the glasses frame are respectively embedded in the inner cavities of the limit grooves opened on the two limit plates, and then the fixing clamp is loosened, and the opening of the limit groove is sealed by the fixing clamp, and the glasses frame is fixed in the limit groove, and the glasses frame can be processed. Since the spacing between the two limit plates can be adjusted according to the size of the glasses frame, the problem that the existing clamp cannot be adaptively adjusted according to the size of the glasses frame, which makes it very inconvenient for users to use when processing glasses frames of different sizes, is avoided as much as possible.

[0010] Optionally, the bottom plate is in a rectangular plate structure, and fixing holes are provided at both ends of the bottom plate for users to fix the bottom plate conveniently.

[0011] By adopting the above technical solution, a base plate is provided to lower the center of gravity of the entire device, improve the stability of the entire device, and fixing holes are provided to facilitate users to connect the base plate to the external frame after passing external bolts through the fixing holes.

[0012] Optionally, the support assembly is a support rod disposed between the base plate and the connecting seat, the support rod is divided into two sections, and the two support rods are slidably connected to each other.

[0013] By adopting the above technical solution, two sections of support rods that are slidably connected to each other are provided, so that the user can adjust the height of the connecting seat conveniently. After the two sections of the support rods slide to a suitable position, they are fixed by the damping effect between each other.

[0014] Optionally, the crossbeam is in a rectangular plate-like structure, a pin shaft rotatably connected to the crossbeam is passed through the middle section of the crossbeam, and the pin shaft passes through the crossbeam and is fixedly connected to the connecting seat.

[0015] By adopting the above technical solution, a pin is set to rotatably connect the crossbeam and the connecting seat. When the user has finished processing the upper surface of the eyeglass frame, the crossbeam can be rotated 180 degrees to rotate the lower surface of the eyeglass frame upward for processing.

[0016] Optionally, a sliding hole with an inner cavity cross-section size that matches the cross-section size of the end of the beam is opened on the adjustment seat, and the adjustment seat is sleeved on the beam through the sliding hole and is slidably connected to the beam.

[0017] By adopting the above technical solution, a sliding hole is provided for slidingly connecting the adjustment seat and the cross beam, and the cross-sectional size of the inner cavity of the sliding hole is adapted to the cross-sectional size of the end of the cross beam, so as to guide the moving path of the adjustment seat.

[0018] Optionally, a protective pad made of flexible material is bonded to the inner wall of the limiting groove and the side of the fixing clip close to the limiting groove.

[0019] By adopting the above technical solution, a protective pad is provided to protect the eyeglass frame, so as to avoid the eyeglass frame from vibrating frequently during processing and colliding with the inner wall of the limit groove or the fixing clip, which may easily cause damage and deformation of the eyeglass frame.

[0020] Optionally, two slide grooves are provided on the connecting seat below the cross beam, and a limit slider is slidably connected in the inner cavity of the two slide grooves, and one end of the limit slider located in the inner cavity of the slide groove is fixedly connected to a spring.

[0021] By adopting the above technical solution, when the spring is not under force, the limit slider extends away from the end of the spring to the bottom of the beam to support the beam and prevent the beam from rotating around the pin shaft. When the beam needs to be rotated, the limit slider can be squeezed into the slide groove, thereby squeezing the spring to contract and making the limit slider slide completely into the slide groove. At this time, the user can rotate the beam to turn over the glasses frame.

[0022] Optionally, the spacing between adjacent sides of two limit sliding blocks is equal to the width of the crossbeam.

[0023] By adopting the above technical solution, when the user needs to process both ends of the eyeglass frame, the crossbeam can be rotated so that the length direction of the crossbeam is flush with the height direction of the support rod. At this time, the two limit sliders can just clamp from both sides of the crossbeam to fix the crossbeam.

[0024] In summary, the beneficial effects of this application are as follows:

[0025] The present application achieves coordinated settings among structures such as a crossbeam, an adjustment seat, a sliding hole, a limit bolt and a limit plate. The adjustment seat is slidably connected to the crossbeam through the sliding hole. When in use, the user can adjust the distance between the adjustment seats at both ends of the crossbeam according to the size of the eyeglass frame, and then screw the limit bolt into the adjustment seat to squeeze the crossbeam to increase the friction between the adjustment seat and the crossbeam, thereby fixing the adjustment seat and the crossbeam relatively. The eyeglass frame can be clamped on the limit plate by a fixing clamp for processing, thereby avoiding as much as possible the problem that the existing clamp cannot be adaptively adjusted according to the size of the eyeglass frame, causing the user to be very inconvenient when processing eyeglass frames of different sizes.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] See also Figure 1-3 A glasses frame processing fixture comprises a base plate 1, and a connecting seat 4 is fixedly mounted on the upper surface of the base plate 1 through a supporting assembly.

[0032] A crossbeam 5 is installed on one side of the connecting seat 4, and a clamping device is connected to the crossbeam 5 through an adjusting component. When in use, the user can adjust the position of the clamping device through the adjusting component, so as to facilitate the clamping and fixing of eyeglass frames of different sizes.

[0033] The adjustment assembly includes two adjustment seats 7 slidably connected at both ends of the beam 5. The top walls of the two adjustment seats 7 are each provided with a limit bolt 9 screwed to the adjustment seat 7. When the user slides the adjustment seat 7 along the beam 5 to a suitable position, the limit bolt 9 can be screwed into the adjustment seat 7 to squeeze the beam 5 to increase the friction between the beam 5 and the adjustment seat 7, thereby fixing the adjustment seat 7 and the beam 5 relatively.

[0034] The clamping assembly includes a limit plate 10 fixedly connected to the adjacent sides of the two adjustment seats 7. The two limit plates 10 are each provided with a limit groove 11 for accommodating the eyeglass frame. The two adjustment seats 7 are also fixedly provided with a fixing clamp 12 for clamping and limiting the eyeglass frame. The user can open the fixing clamp 12 and then embed the two sides of the eyeglass frame into the inner cavity of the limit groove 11 provided on the two limit plates 10 respectively, and then release the fixing clamp 12 and use the fixing clamp 12 to seal the opening of the limit groove 11, thereby fixing the eyeglass frame in the limit groove 11, which is convenient for subsequent processing of the eyeglass frame.

[0035] Reference Figure 1 The bottom plate 1 is a rectangular plate structure, and fixing holes 2 are provided at both ends of the bottom plate 1 for users to fix the bottom plate 1 conveniently. The bottom plate 1 is provided to lower the center of gravity of the entire device and improve the stability of the entire device. The fixing holes 2 are provided so that users can conveniently connect the bottom plate 1 to the external frame after passing the external bolts through the fixing holes 2.

[0036] Reference Figure 1The supporting assembly is a supporting rod 3 disposed between the bottom plate 1 and the connecting seat 4. The supporting rod 3 is divided into two sections, and the two supporting rods 3 are slidably connected to each other. The two sections of the supporting rod 3 slidably connected to each other are provided to facilitate the user to adjust the height of the connecting seat 4. After the two sections of the supporting rod 3 slide to a suitable position, they are fixed by the damping effect between each other.

[0037] Reference Figure 3 The crossbeam 5 is a rectangular plate-shaped structure, and a pin 6 is provided in the middle section of the crossbeam 5 to be rotatably connected to the crossbeam 5. The pin 6 passes through the crossbeam 5 and is fixedly connected to the connecting seat 4. The pin 6 is provided to rotatably connect the crossbeam 5 to the connecting seat 4. When the user has finished processing the upper surface of the eyeglass frame, the crossbeam 5 can be rotated 180 degrees to rotate the lower surface of the eyeglass frame to the upper side for processing.

[0038] Reference Figure 2 The adjusting seat 7 is provided with a sliding hole 8 whose inner cavity cross-section size matches the cross-section size of the end of the beam 5. The adjusting seat 7 is sleeved on the beam 5 through the sliding hole 8 and is slidably connected to the beam 5. The sliding hole 8 is provided for slidably connecting the adjusting seat 7 with the beam 5. The inner cavity cross-section size of the sliding hole 8 matches the cross-section size of the end of the beam 5, and is used to guide the moving path of the adjusting seat 7.

[0039] Reference Figure 1 The inner wall of the limit groove 11 and the side of the fixing clip 12 close to the limit groove 11 are both bonded with a protective pad made of a flexible material. The protective pad is provided to protect the eyeglass frame and to avoid the eyeglass frame from vibrating frequently during processing and colliding with the inner wall of the limit groove 11 or the fixing clip 12, which may easily cause damage and deformation of the eyeglass frame.

[0040] Reference Figure 3 Two slide grooves 13 are provided on the connecting seat 4 below the cross beam 5. The inner cavities of the two slide grooves 13 are both slidably connected with limit sliders 14. One end of the limit slider 14 located in the inner cavity of the slide groove 13 is fixedly connected with a spring 15. When the spring 15 is not subjected to force, the limit slider 14 extends to the bottom of the cross beam 5 away from the spring 15 to support the cross beam 5 and prevent the cross beam 5 from rotating around the pin 6. When the cross beam 5 needs to be rotated, the limit slider 14 can be squeezed into the slide groove 13, thereby squeezing the spring 15 to contract and making the limit slider 14 completely slide into the slide groove 13. At this time, the user can rotate the cross beam 5 to turn over the eyeglass frame.

[0041] Reference Figure 1 and Figure 3 , the distance between the adjacent sides of the two limit sliders 14 is equal to the width of the beam 5. When the user needs to process the two ends of the eyeglass frame, the beam 5 can be rotated to make the length direction of the beam 5 flush with the height direction of the support rod 3. At this time, the two limit sliders 14 can just clamp the beam 5 from both sides to fix the beam 5.

[0042] When the eyeglass frame is in the working state, the user can first slide the adjusting seats 7 provided at the two ends of the cross beam 5 along the length direction of the cross beam 5 according to the size of the eyeglass frame to be processed, adjust the two adjusting seats 7 to the appropriate positions, and then screw the limiting bolts 9 into the adjusting seats 7 to squeeze the cross beam 5 to increase the friction between the adjusting seats 7 and the cross beam 5, so that the adjusting seats 7 and the cross beam 5 are relatively fixed. At this time, after opening the fixing clamp 12, the two sides of the eyeglass frame are respectively embedded in the inner cavities of the limiting grooves 11 opened on the two limiting plates 10, and then the fixing clamp 12 is loosened, and the opening of the limiting groove 11 is sealed by the fixing clamp 12, and the eyeglass frame is fixed in the limiting groove 11, and the eyeglass frame can be processed. Since the spacing between the two limiting plates 10 can be adjusted according to the size of the eyeglass frame, the problem that the existing clamp cannot be adaptively adjusted according to the size of the eyeglass frame, which makes it very inconvenient for users to use when processing eyeglass frames of different sizes, is avoided as much as possible.
