Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for micro-painted enamel processing, specifically a clamping device for micro-painted enamel. Background Technology

[0002] Miniature enamel painting is a technique that involves drawing intricate floral, bird, and decorative patterns on a thin enamel substrate. The process requires frequent adjustments to the workpiece's tilt and rotation angles to match the direction of the brush tip, demanding extremely high flexibility and stability in the clamping mechanism. Existing clamping devices for miniature enamel painting still have the following problems in use:

[0003] Existing clamps mostly adopt a fixed structure. Angle adjustment requires disassembling the workpiece and re-fixing it, which is cumbersome and easy to scratch and damage the fine details of the drawn pattern. At the same time, frequent adjustments will interrupt the drawing rhythm and affect the smoothness of the micro-painting operation.

[0004] Miniature enamel workpieces have a wide size range (such as enamel pendants with a diameter of 1cm to enamel plaques with a diameter of 5cm). The existing clamping devices are mostly adjustable by snap-on or simple sliding rails, which are not precise enough. After clamping, they are prone to loosening and shifting due to uneven force, resulting in misaligned lines, distorted patterns, and reduced quality of finished products. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a clamping device for micro-painted enamel, which is equipped with a rotatable clamping component and a precisely adjustable manual drive component, thus solving the problems of cumbersome angle adjustment and easy damage to the image, as well as inaccurate clamping spacing adjustment and easy loosening of existing clamping devices.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for micro-painted enamel, comprising a fixing component, wherein the fixing component is configured with a movable component, a manual drive component, and a clamping component; the fixing component includes a fixing base, wherein a sliding groove is formed between the two lower side walls of the fixing base, the sliding groove being used to provide stable sliding guidance for the movable component; support mounting components are provided on the front and rear sides of the fixing base to improve the overall placement stability of the device; the movable component includes a slider slidably connected within the sliding groove, the slider and the sliding groove being adapted to ensure smooth sliding, and a movable seat being fixedly connected to the end of the slider away from the fixing base; the manual drive component is disposed between the movable seat and the fixing base, and is used to precisely adjust the distance between the movable seat and the fixing base; the top ends of the fixing base and the movable seat are kept flush to ensure the coaxiality of the clamping component; the clamping component includes clamping seats rotatably disposed on the top ends of the fixing base and the movable seat, the two clamping seats being symmetrically arranged for clamping and fixing the two ends of the enamel piece.

[0009] As a further improvement of this utility model: the support and installation assembly includes a support frame fixedly connected to the lower middle part of the front and rear ends of the fixed base. The L-shaped support frame can increase the contact area between the device and the placement surface and improve the placement stability.

[0010] As a further improvement of this utility model: the support frame is an L-shaped frame, and a waist-shaped hole is provided between the upper and lower side walls of the support frame. The waist-shaped hole facilitates the use of fasteners to fix the device on the workbench, further improving the stability during use.

[0011] As a further embodiment of this utility model: the manual drive assembly includes a rotating support fixedly installed on the fixed base near the moving base. A screw is horizontally rotatably connected to the rotating support, and a crank is fixedly connected to the end of the screw away from the fixed base. By rotating the crank, the screw can be driven to rotate, thereby driving the moving base to move smoothly and achieving precise adjustment of the clamping distance.

[0012] As a further improvement of this utility model, a threaded hole is provided between the two side walls of the movable seat for threaded connection of the screw. The threaded hole and the screw are threaded together, which converts the rotation of the screw into the linear movement of the movable seat, ensuring the accuracy and stability of the adjustment.

[0013] As a further embodiment of this utility model: the top ends of both the fixed base and the movable base are fixedly connected to bearing seats, and the bearing seats are equipped with double ball bearings. The double ball bearings can reduce the frictional resistance when the connecting shaft rotates and improve the smoothness of rotation. The connecting shaft is installed inside the double ball bearings.

[0014] As a further embodiment of this utility model: the two connecting shafts are fixedly connected to the corresponding clamping base at one end facing each other, and a handwheel is fixedly connected to the end of one connecting shaft away from the clamping base. By rotating the handwheel, the connecting shaft and the clamping base can be rotated synchronously, thereby adjusting the angle of the enamel part after clamping, which is convenient for micro-painting operation.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by setting a clamping assembly with a handwheel and double ball bearings, rotating the handwheel can drive the connecting shaft and the clamping seat to rotate synchronously. The low friction characteristics of the double ball bearings enable angle adjustment without jamming. During micro-drawing, the drawing angle can be flexibly switched without disassembling the workpiece, which not only avoids the risk of damage to the drawn pattern, but also maintains the continuity of the drawing operation, effectively improving the efficiency of micro-drawing.

[0017] 2. In this utility model, the screw and threaded hole of the manual drive component are precisely matched, and the guide effect of the slide groove on the moving seat can be combined to accurately control the clamping distance to adapt to enamel workpieces of different sizes. At the same time, the self-locking characteristic of the thread drive and the close support of the slider make the workpiece evenly stressed after clamping and not easy to loosen, avoiding the misalignment of lines caused by workpiece offset during the drawing process, and improving the precision of the micro-drawing pattern and the finished product qualification rate.

The sliding groove 12 provides a stable sliding guide for the movable component 2. Support mounting components are provided on the front and rear sides of the fixing base 11 to improve the overall placement stability of the device. The movable component 2 includes a slider 21 slidably connected to the sliding groove 12. The slider 21 and the sliding groove 12 are connected to the movable component 21. The groove 12 is adapted to ensure smooth sliding. The slider 21 is fixedly connected to the movable seat 22 at the end away from the fixed base 11. The manual drive component 3 is set between the movable seat 22 and the fixed base 11 to precisely adjust the distance between the movable seat 22 and the fixed base 11. The tops of the fixed base 11 and the movable seat 22 are kept flush to ensure the coaxiality of the clamping component 4. The clamping component 4 includes a clamping seat 44 rotatably set at the tops of the fixed base 11 and the movable seat 22. The two clamping seats 44 are symmetrically arranged to clamp and fix the two ends of the enamel piece.

[0027] The support and installation components include a support frame 13 fixedly connected to the lower center of the front and rear ends of the fixed base 11. The L-shaped support frame 13 can increase the contact area between the device and the placement surface, thereby improving the placement stability.
