Description

Technical Field

[0001] The utility model relates to the technical field of glassware production and processing, and particularly relates to a general positioning tooling for engraving words on glassware. Background Art

[0002] During the laser engraving process, it is necessary to ensure the fixed position of the cup. Otherwise, the text or pattern will deviate, resulting in unqualified engraving and scrapping of the cup. Especially for special-shaped cups, due to their irregular shapes, conventional fixing methods may not be able to ensure the stability and positioning accuracy of the cup during the engraving process, thus affecting the engraving effect. Therefore, some fixtures that can position products of different shapes have been designed on the market. For example, the prior art "a profiling fixture" (publication number: CN218364176U) discloses a structure of a profiling fixture that can be based on the shape of the product. However, the prior art still has the following technical problems:

[0003] The prior art adopts a technical solution of multiple compression rods cooperating with springs. When the product is placed on multiple compression rods, the height of the compression rods will change according to the shape of the product, so that multiple compression rods form a shape that fits the outer shape of the product to achieve the support of the product. However, in order to keep the position of the compression rods fixed, the prior art uses pneumatic or hydraulic means to deform the serpentine spring piece, so as to tightly press each compression rod for fixation. The use of hydraulic pressure or pneumatic pressure requires the installation of a hydraulic pump or a pneumatic pump, as well as some devices such as a hydraulic cylinder or a cylinder. This not only requires additional facilities and high costs, but also pneumatic pressure or hydraulic pressure may fluctuate, resulting in insecure clamping and positioning of the compression rods, unstable support of the product, poor engraving effect, and scrapping of the cup. Content of the Utility Model

[0004] The utility model provides a general positioning tooling for engraving words on glassware, which can solve the problems of high cost consumption of the positioning fixture in the prior art, and easy poor stability of the product when supported by the fixture, resulting in poor engraving effect and even scrapping of the product.

[0005] The present application provides the following technical solution: A general positioning tooling for engraving words on glassware, comprising a base, an annular top seat detachably connected to the base, a plurality of profiling sleeves fixed on the base, and a locking mechanism for fixing the positions of the profiling sleeves;

[0006] The locking mechanism includes a frame plate slidably connected in the annular top seat, a plurality of abutting plates equally spaced and fixed on the frame plate, and a handle rotatably connected to one end of the frame plate; the plurality of abutting plates and the plurality of profiling sleeves are arranged at intervals;

[0007] One end of the handle close to the frame plate is fixed with a rotating rod. The rod part of the rotating rod is threadedly connected with the annular top seat. One end of the frame plate is fixedly connected with a bearing. The end of the rotating rod away from the handle extends into the inner ring of the bearing and is fixed. A pin is fixed at the end of the frame plate away from the handle, and the pin is slidably connected with the annular top seat.

[0008] Beneficial effects:

[0009] 1. Precise positioning and fixation: Due to the spaced arrangement of the frame plate and the pressing plate, by rotating the handle, the frame plate and the pressing plate can be driven to apply a pressing force to the side of the profiling sleeve, so as to achieve stable positioning of the profiling sleeve. This design ensures that during the engraving process, the glassware can be stably supported above the profiling sleeve, avoiding pattern or text engraving errors caused by unstable positioning of the glassware, thereby improving the engraving effect.

[0010] 2. Simple and efficient operation: Just turn the handle to easily move the frame plate, and then adjust the position of the pressing plate. Compared with the existing technology using hydraulic or pneumatic positioning drive methods, the operation process is simplified, time is saved, and work efficiency is improved, especially suitable for production environments that require frequent workpiece replacement.

[0011] 3. Adaptability and flexibility: This mechanism can adapt to profiling sleeves of different sizes and shapes, improving the versatility and flexibility of the tooling. The same set of tooling can be used to fix various types of glassware, reducing the need for special tooling and lowering production costs.

[0012] 4. Convenient maintenance and servicing: This locking mechanism has a relatively simple structure and is easy to maintain and service. Key components such as the handle, rotating rod, and pin are easy to inspect and replace, reducing the maintenance cost during long-term operation.

[0013] Furthermore, a groove is provided on the base. The opening of the groove is the same size as the inner hole of the annular top seat, and the profiling sleeve is located in the groove.

[0014] Beneficial effects: Since the size of the groove matches the inner hole of the annular top seat, it makes the loading and unloading of the profiling sleeve easier. That is, the profiling sleeve can be easily installed into the groove of the base, and the design of the groove provides additional support and protection for the profiling sleeve, reducing possible damage to the profiling sleeve during operation and extending its service life.

[0015] Furthermore, the profiling sleeves are fixed in the grooves of the base in an equidistant array.

[0016] Beneficial effects: The equidistant array layout ensures the uniformity of the supporting force of the glassware on the profiling sleeve. Regardless of its shape, the glassware can obtain balanced contact points, avoiding deformation or damage caused by excessive local pressure.

[0017] Further, the profiling sleeve includes a sliding column fixed to the bottom of the groove of the base, a compression spring sleeved on the rod portion of the sliding column, and a sliding sleeve slidably connected to the sliding column.

[0018] Beneficial effects: The top of the sliding sleeve is used to support the glassware. The compression spring enables the sliding sleeve to be compressed to different heights according to the different shapes of the glassware. Even for irregular glassware, the sliding sleeve can fit precisely, providing support and positioning for the glassware. At the same time, the compression spring is also used to enable the sliding sleeve to reset by relying on the elastic force of the compression spring after the glassware is taken away from the top of the sliding sleeve.

[0019] Further, a layer of rubber plate is also fixed on the pressing plate, and the rubber plate is located on the side where the pressing plate is in pressing contact with the sliding sleeve.

[0020] Beneficial effects: The rubber plate has a high coefficient of friction, which can increase the friction force between the pressing plate and the sliding sleeve, ensuring the stability of positioning during the process of fixing the position of the sliding sleeve by turning the handle, preventing the sliding sleeve from shifting due to external force or vibration, avoiding the movement of the support position of the glassware. At the same time, the rubber material is soft and elastic, which can effectively avoid scratching or damage to the sliding sleeve and extend the service life of the device.

[0028] Embodiment 1

[0029] As Figures 1 to 5As shown in the figure, a general positioning tooling for engraving words on glassware includes a base 3, an annular top seat 1 detachably connected to the base 3, a plurality of profiling sleeves fixed on the base 3, and a locking mechanism for fixing the positions of the profiling sleeves; as Figure 1 shown, protrusions are provided on both sides of the lower end of the base 3. The protrusions can be used to connect screws, and the base 3 is fixed on the working table of the laser engraving machine through the screws. A groove is provided on the base 3, and the notch of the groove is of a stepped shape. The lower port part of the annular top seat 1 is also of a stepped shape, so that the annular top seat 1 can be snapped into the stepped notch on the base 3, and the two are in transitional fit, which is convenient for disassembly and assembly.

[0030] The locking mechanism includes a frame plate 6 located in the deep groove formed after the annular top seat 1 and the base 3 are spliced, a plurality of abutting plates 4 equally spaced and fixed on the frame plate 6, and a handle 8 rotatably connected to one end of the frame plate 6; as Figure 1 and Figure 3 shown, a pin 2 is vertically fixed on the side wall of the left end of the frame plate 6. One end of the pin 2 extends from the inside to the outside of the annular top seat 1, and the pin 2 is slidably connected to the annular top seat 1; as Figure 5 shown, a bearing 11 is fixedly installed inside the side wall of the right end of the frame plate 6. A rotating rod 7 is fixed to the inner ring of the bearing 11. The rod part of the rotating rod 7 is Figure 1 threadedly connected to the side wall of the annular top seat 1 in Figure 1 、 Figure 3 and Figure 4 shown, the abutting plates 4 are vertically and equally spaced and fixed above the frame plate 6. A layer of rubber plate is also fixed on the abutting plates 4, and the rubber plate is located on the side where the abutting plates 4 need to abut and contact the sliding sleeve 5.

[0031] The plurality of abutting plates 4 are arranged at intervals from the plurality of profiling sleeves; as Figure 1 and Figure 2 shown, the profiling sleeve includes a sliding column 9 threadedly connected to the bottom of the groove of the base 3, a compression spring 10 sleeved on the rod part of the sliding column 9, and a sliding sleeve 5 slidably connected to the sliding column 9. And the maximum outer diameter of the compression spring 10 on each sliding column 9 is smaller than the minimum outer diameter of the corresponding sliding sleeve 5. The upper end of the sliding sleeve 5 extends out of the top of the annular top seat 1, and the plurality of abutting plates 4 are arranged at intervals from the plurality of sliding sleeves 5; the whole profiling sleeve is uniformly fixed in the groove of the base 3 in an equidistant array manner.

[0032] The usage method of this tooling is as follows:

[0033] Place the cup mouth of the glass to be engraved in a horizontal state on the top of the sliding sleeve 5, so that the outer circumferential surface of the cup contacts the top end of the sliding sleeve 5, and apply a certain downward pressure to the cup slightly. Then, under the action of the pressure, the sliding sleeve 5 slides downward along the sliding column 9. At the same time, due to the different shapes of each part of the cup, the sliding heights of the multiple sliding sleeves 5 are different, thus forming a supporting surface that fits the surface shape of the cup. The top of the sliding sleeve 5 forms a point support on the surface of the glass cup. At this time, rotate the handle 8 to make the rotating rod 7 move axially into the annular top seat 1, then Figure 1 the middle frame plate 6 and the pressing plate 4 will move leftward as a whole, and the rubber layer on the surface of the pressing plate 4 will press against the side walls of each column of sliding sleeves 5, thereby locking the positions of all sliding sleeves 5. At this time, the glass cup is stably supported on the top of the sliding sleeve 5, and the outer circumferential surface of the cup can be laser engraved; after engraving is completed, rotate the handle 8 in the reverse direction to make the rubber layer on the surface of the pressing plate 4 separate from the side wall surface of the sliding sleeve 5, and the elastic force of the compression spring 10 causes all sliding sleeves 5 to reset, and then the positioning and engraving of the next cup can be carried out.
