Description

Technical Field

[0001] This utility model relates to the field of glass mold clamping technology, and in particular to an adjustable glass mold clamping device. Background Technology

[0002] In the machining of glass molds, the stability and precision of the clamps directly affect the machining quality and efficiency. Traditional glass mold clamps mostly adopt a fixed jaw structure, achieving clamping through bolts or manual adjustment mechanisms, which has the following technical drawbacks:

[0003] (1) Low adjustment efficiency: When manually adjusting the jaw spacing, the bolts need to be tightened and loosened repeatedly, which is cumbersome and difficult to ensure symmetry, which seriously affects production efficiency, especially in mass production.

[0004] (2) Poor clamping adaptability: When the mold size changes, traditional clamps need to be replaced with corresponding jaws or pads, which cannot quickly adapt to the clamping requirements of workpieces of different specifications.

[0005] (3) Insufficient positioning accuracy: Fixed jaws are prone to uneven force when clamping irregular or curved molds, causing processing vibration or workpiece displacement, which affects dimensional accuracy;

[0006] (4) Low level of automation: Although hydraulic or pneumatic clamps can improve clamping efficiency, they lack coordinated design with mechanical adjustment mechanisms, making it difficult to balance coarse adjustment (rapid positioning) and fine adjustment (precise clamping) functions. Utility Model Content

[0017] Furthermore, the first jaw is mounted on the first jaw base via a slewing bearing for adaptive rotation.

[0018] Furthermore, a buffer elastic layer is provided on the clamping surfaces of both the first jaw and the second jaw.

[0019] Furthermore, it also includes a connecting piece. The base of the hydraulic cylinder has first fixing holes on both sides, and the side of the clamp body has several second fixing holes along the axial direction. One end of the connecting piece is connected to the first fixing hole through a fixing member, and the other end of the connecting piece is connected to any of the second fixing holes through a fixing member, so as to lock the hydraulic cylinder base and the clamp body together.

[0020] Furthermore, one end of the connecting piece connected to the second fixing hole has an elongated waist-shaped hole, and the fixing member passes through the elongated waist-shaped hole and connects to the second fixing hole. The axial position of the oil cylinder can be adjusted by sliding the elongated waist-shaped hole.

[0025] Furthermore, the coordinated operation of the guide groove and the slider ensures the stability of the jaw clamp during operation and prevents movement or swaying during operation.

[0026] Furthermore, the jaws feature a dual design of slewing bearings and a buffer elastic layer, enabling them to adapt to glass molds of different shapes, effectively protecting the workpiece surface and reducing the breakage rate during clamping.

[0027] Furthermore, by setting a connecting piece that cooperates with multiple sets of second fixing holes, the jaws can flexibly adapt to different working strokes, thus improving versatility.

[0028] Furthermore, the hinged cover assembly provides fully enclosed protection for critical transmission components, isolates metal debris, and significantly extends the service life of the lead screw. Attached Figure Description

[0044] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] See Figures 1 to 3 This utility model discloses an adjustable glass mold clamp, which includes a mounting plate 1, a clamp body 2, a first jaw assembly 3, a second jaw assembly 4, a hydraulic cylinder 5, and a lead screw 6. The clamp has a compact structure, is flexible in adjustment, and can adapt to the clamping requirements of glass molds of different sizes, while also possessing good stability and cushioning performance.

[0046] Specifically, mounting plate 1 is used to fix the fixture to the worktable of a machine tool. Its bottom can be connected to the machine tool table surface by bolts or other fasteners to ensure the stability of the overall fixture.

[0047] The clamp body 2 is fixedly connected to the mounting plate 1. Specifically, a fixing groove 202 is provided on the side of the clamp body 2, and a pressure block 7 is embedded in the fixing groove 202. A first positioning hole 101 is provided on the mounting plate 1 at the position corresponding to the pressure block 7. A second positioning hole 701 coaxial with the first positioning hole 101 is provided on the pressure block 7. By setting positioning pins or bolts or other positioning components through the first positioning hole 101 and the second positioning hole 701, the pressure block 7 can be pressed between the clamp body 2 and the mounting plate 1, thereby achieving precise positioning and firm fixation of the clamp body 2.

[0048] A guide groove 201 is provided inside the clamp body 2. The cross-sectional shape of the guide groove 201 can be T-shaped, dovetail-shaped, or other structures suitable for sliding, to ensure the smooth movement of the second jaw assembly 4.

[0049] The first jaw assembly 3 includes a first jaw base 301 and a first jaw 302. The first jaw base 301 is fixed to one end of the jaw body 2 and can be connected to the jaw body 2 by welding or bolts to ensure structural strength. The first jaw 302 is mounted on the first jaw base 301 via a slewing bearing 8, allowing the first jaw 302 to self-adaptively rotate around its axis, thereby automatically adjusting its angle when clamping the glass mold and improving the clamping fit and stability.

[0050] The second jaw assembly 4 includes a second jaw base 401 and a second jaw 402. The bottom of the second jaw base 401 is provided with a slider 403 adapted to a guide groove 201. The slider 403 can slide within the guide groove 201 to achieve axial movement of the second jaw assembly 4. The second jaw 402 is fixed to the second jaw base 401, and together with the first jaw 302, it forms a clamping area.

[0051] To improve clamping stability and prevent damage to the glass mold surface, buffer elastic layers (such as rubber pads, polyurethane pads, etc.) are provided on the clamping surfaces of the first jaw 302 and the second jaw 402 to absorb vibration and impact during the clamping process.

[0052] The cylinder body of hydraulic cylinder 5 is fixed on the clamp body 2, and its piston rod is connected to the second jaw base 401 to provide axial thrust, driving the second jaw assembly 4 to move along the guide groove 201, thereby realizing the clamping or releasing action. Hydraulic cylinder 5 can be hydraulically driven, or it can be replaced by a pneumatic cylinder, depending on the actual working conditions.

[0053] The lead screw 6 is supported on the jaw body 2 by a bearing seat and engages with a threaded hole on the slider 403. By rotating the lead screw 6, the position of the second jaw base 401 can be finely adjusted, thereby precisely controlling the jaw spacing to accommodate glass molds of different sizes. A handwheel or servo motor can be installed at the end of the lead screw 6 for manual or automatic adjustment.

[0054] In this example, a connecting piece 9 is also provided. The base of the hydraulic cylinder 5 has first fixing holes 501 on both sides. The side of the clamp body 2 has several second fixing holes 203 along the axial direction. One end of the connecting piece 9 is connected to the first fixing hole 501 by bolts or other fasteners. The other end of the connecting piece 9 is also connected to any of the second fixing holes 203 by bolts or other fasteners, thereby connecting and locking the base of the hydraulic cylinder 5 to the clamp body 2.

[0055] One end of the connecting piece 9 that connects to the second fixing hole 203 has an oblong hole 901. The fixing member passes through the oblong hole 901 and connects to the second fixing hole 203. When it is necessary to adjust the axial position of the hydraulic cylinder 5, the fixing member can be loosened so that the connecting piece 9 slides along the oblong hole 901, thereby adapting to the change in the installation position of the hydraulic cylinder 5. After the adjustment is completed, the fixing member is tightened again.

[0056] A cover plate assembly 10 is connected to the base end of the hydraulic cylinder 5 to protect the lead screw 6 and prevent metal shavings generated during machining from contaminating the lead screw 6 and affecting its adjustment accuracy. The cover plate assembly 10 includes a first cover plate 1001 and a second cover plate 1002, which are hinged together for easy opening and closing to maintain or adjust the lead screw 6.

[0057] In the actual operation, first fix the mounting plate 1 on the machine tool, then rotate the lead screw 6 according to the size of the glass mold to initially adjust the position of the second jaw assembly 4. Start the hydraulic cylinder 5 to push the second jaw 402 towards the first jaw 302 until it clamps the glass mold. After clamping, the first jaw 302 can rotate adaptively to ensure that the clamping surface is fully in contact with the mold surface. After processing is completed, the hydraulic cylinder 5 retracts, releasing the mold, and the next process can be carried out.

[0058] In summary, the adjustable glass mold clamp disclosed in this utility model optimizes the combination of core components such as mounting plate 1, clamp body 2, jaw assembly and drive mechanism, which not only enables quick disassembly and maintenance of each component, but also significantly improves the stability and service life of the overall system.

[0059] Specifically, a dual-drive mode is adopted, with the hydraulic cylinder 5 and the lead screw 6 working in tandem. This ensures a secure fixation during the machining process while allowing the fixture to be adapted to various sizes of glass molds. This guarantees both operational efficiency and meets the stringent positioning accuracy requirements of precision machining.

[0060] In addition, the first jaw 302 achieves deflection adjustment through the slewing bearing 8, and with the help of the buffer elastic layer, it can effectively reduce the mold damage rate during processing. At the same time, the design of the quick-opening and closing protective cover plate shortens the maintenance time of the lead screw 6; the structure of the connecting piece 9 and the waist-shaped adjustment hole position make the position adjustment of the hydraulic cylinder 5 more flexible.

[0061] In summary, the glass mold fixture disclosed in this utility model, while ensuring the reliability of fixture operation, achieves a comprehensive improvement in ease of operation, processing accuracy and service life.

[0062] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
