Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture for clamping glass molds for plasma spray welding. Background Technology

[0002] In the glass manufacturing industry, glass molds, as the core component for forming, directly determine the precision, appearance, and production stability of glass products through their surface quality and service life. Because glass molds operate in high-temperature, high-pressure environments and frequently come into contact with molten glass, their surfaces are prone to wear, corrosion, and cracking. This not only leads to defects such as scratches and deformation in glass products but also significantly shortens mold replacement cycles, increasing production costs for companies. Therefore, the industry commonly uses plasma spraying to strengthen the surface of glass molds. By fusing a high-hardness, high-wear-resistant alloy coating onto the mold surface, the surface performance of the mold is significantly improved, its service life is extended, and the risk of production interruptions due to mold wear is reduced. However, plasma spraying places extremely high demands on the clamping accuracy and stability of glass molds. On the one hand, glass molds have diverse structures; common cup molds and bottle molds not only differ in shape, but some also have complex cavities or curved surface structures. Traditional clamping fixtures often use a universal design, making it difficult to adapt to glass molds with different structures, resulting in inaccurate positioning during clamping. On the other hand, during plasma spraying, the spraying gun releases a high-temperature plasma arc and needs to move continuously along the mold surface. If the mold is not securely clamped, it is prone to displacement, shaking, or even slight rotation under the influence of high temperature or slight impact from the spraying gun. This can cause problems such as uneven coating thickness and insufficient bonding strength between the coating and the mold substrate. In mild cases, this can lead to localized coating peeling, requiring re-spraying and repair, increasing labor costs; in severe cases, it can cause defects such as incomplete or over-welded coatings on the mold surface, directly leading to the scrapping of the entire mold and causing unnecessary economic losses to the company.

[0003] In summary, the current field of plasma spraying for glass molds urgently needs a clamping fixture that can adapt to molds of different structures, achieve accurate positioning and stable clamping, and at the same time take into account ease of operation and mold protection, so as to meet the industry's high-quality production requirements for plasma spraying of glass molds. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a fixture for clamping glass molds during plasma spraying, which solves the technical problem of inaccurate positioning of glass molds during plasma spraying in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a clamping fixture for plasma spraying of glass molds, used for clamping glass molds, comprising: frame; Mounting bracket, which is rotatably mounted on the frame; Mounting base, detachably mounted on the mounting frame, the mounting base having an upward-facing receiving groove; A support member, which is elliptical and disposed within the receiving groove, and the support member has a placement groove for accommodating a glass mold; The mounting base includes at least two limiting plates. The two limiting plates are symmetrically arranged on the top of the mounting base. The limiting plates are used to limit the top and / or sidewalls of the glass mold. The limiting plates can cooperate with the support member to clamp and limit the glass mold.

[0006] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, the mounting frame is U-shaped, and two mounting rods are symmetrically arranged on the mounting frame. The two mounting rods are parallel to each other and the ends of the two mounting rods away from the mounting frame extend in the same direction. The mounting base has a through hole, and the mounting base is slidably connected to the mounting rod through the through hole.

[0007] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, a telescopic member is provided below the mounting base. The telescopic member has a fixed section and a movable section. The fixed section is fixedly disposed on the bottom surface of the mounting base, and the movable section penetrates the bottom surface of the mounting base and extends into the receiving groove. The support member is disposed on the movable section. The telescopic member is used to drive the support member to rise so as to cooperate with the limiting plate to limit the glass mold.

[0008] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, a rotation drive component is further included. The rotation drive component is fixedly mounted on the frame, and the drive end of the rotation drive component is connected to the mounting frame. The rotation drive component is used to drive the mounting frame to swing back and forth.

[0009] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, two sliding grooves are provided on the mounting base, the sliding grooves correspond one-to-one with the limiting plate, the length direction of the sliding groove is perpendicular to the axial direction of the mounting rod, and the limiting plate is slidably disposed in the sliding groove; The limiting plate has a threaded hole, which is arranged opposite to the slide groove. The limiting plate is provided with a locking bolt, which is threadedly connected to the threaded hole. The locking bolt can pass through the limiting plate and abut against the mounting base. The locking bolt can be inserted into the slide groove and can be loosened and slid in the slide groove. The mounting base is also provided with a guide rail, the guide rail extends in the same direction as the slide groove, and the guide rail has recesses on its two side walls that are perpendicular to the horizontal plane along its own extension direction. The limiting plate has a guide groove that matches the guide rail.

[0010] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, the placement groove is V-shaped.

[0011] For example, in at least one embodiment of this utility model, a clamping fixture for plasma spraying welding of a glass mold further includes a spraying device, which in turn includes: A bracket, which is mounted on the frame; A movable component is mounted on the support, and a welding gun is installed on the movable end of the movable component; the movable component is used to drive the welding gun to move.

[0012] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, the moving component includes: A lifting frame, which is lifted and mounted on the support; A transverse frame, which is movably mounted on the lifting frame; A longitudinal moving frame is movably mounted on the transverse moving frame, and the welding gun is mounted on the longitudinal moving frame.

[0013] For example, in a glass mold plasma spraying clamping fixture provided in at least one embodiment of the present invention, each of the limiting plates has two guide grooves, the two guide grooves are respectively engaged with two guide rails, and the two guide rails are respectively located at the two ends of the two slide grooves.

[0014] The beneficial effects of this utility model are as follows: In this invention, the cooperation between the support member and the limiting plate allows for the adaptation to glass molds of different sizes. The lower end face of the glass mold is placed in the receiving groove, and the limiting plate can abut against or clamp the two ends of the glass mold with the upper end face. The cooperation between the limiting plate and the support member ensures that the mold does not shift or shake during the spray welding process, avoiding defects such as uneven spray coating and insufficient bonding strength caused by displacement. At the same time, the detachable design of the mounting base facilitates the replacement of the mounting base with a suitable one according to the mold specifications, improving the versatility of the fixture.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0019] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0020] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-5 As shown, this invention illustrates a glass mold plasma spraying clamping fixture according to one embodiment of the present invention. The fixture is used to clamp glass molds and includes a frame 1, which serves as the basic support component of the entire fixture, providing an installation platform for other components. A mounting frame 2 is rotatably mounted on the frame 1. A mounting base 3 is detachably mounted on the mounting frame 2, and the mounting base 3 has an upward-facing receiving groove. A support member 4 is vertically mounted within the receiving groove, and the support member 4 has a placement groove for accommodating the glass mold. At least two limiting plates 5 are provided, symmetrically arranged on the top of the mounting base 3. The limiting plates 5 are used to limit the top or sidewalls of the glass mold, and can cooperate with the support member 4 to clamp and limit the glass mold.

[0025] The cooperation between the support member 4 and the limiting plate 5 allows for the adaptation of glass molds of different heights. It should be noted that in this example, one side of the glass mold is a continuously distributed arc surface along its length (defined as the lower end face), and the other side is a continuously distributed plane along its length (defined as the upper end face). The lower end face of the glass mold is used to place it in the receiving groove, and the limiting plate 5 can abut against or clamp the two ends of the glass mold with the upper end face. The cooperation between the limiting plate 5 and the support member 4 ensures that the mold does not shift or shake during the spray welding process, avoiding defects such as uneven spray coating and insufficient bonding strength caused by displacement. Furthermore, the detachable design of the mounting base 3 facilitates subsequent replacement with a suitable mounting base 3 according to the mold specifications, improving the versatility of the fixture.

[0026] Optionally, the mounting bracket 2 is U-shaped, and two mounting rods 18 are symmetrically arranged on the mounting bracket 2. The two mounting rods 18 are parallel to each other and the ends of the two mounting rods 18 away from the mounting bracket 2 extend in the same direction. The mounting base 3 has a through hole, and the mounting base 3 is slidably connected to the mounting rods 18 through the through hole.

[0027] The mounting base 3 is slidably connected to the mounting rod 18, allowing adjustment of its position on the mounting frame 2. This moves the glass mold closer to or further away from the spray welding device 11, adapting to the spray welding needs of molds of different sizes without requiring the spray welding device 11 to be moved. The U-shaped mounting frame 2 has two ends for mounting limit plates 5, and a receiving groove in the middle for accommodating the glass mold. The glass mold can be raised and lowered within the receiving groove. This structure prevents the mounting frame 2 itself from obstructing the spray welding operation, improving operational convenience.

[0028] Optionally, a telescopic component 6 is provided below the mounting base 3. The telescopic component 6 has a fixed section 61 and a movable section 62. The fixed section 61 is fixedly disposed on the bottom surface of the mounting base 3, and the movable section 62 penetrates the bottom surface of the mounting base 3 and extends into the receiving groove. The support component 4 is disposed on the movable section 62. The telescopic component 6 is used to drive the support component 4 to rise to cooperate with the limiting plate 5 to limit the glass mold. Specifically, in this example, the telescopic component 6 can be a miniature cylinder. It should be noted that the bottom of the telescopic component 6 is not connected to the frame 1, so the telescopic component 6 can swing with the mounting base 3.

[0029] When it is necessary to clamp the glass mold, the movable section 62 of the telescopic component 6 extends upward, driving the support component 4 to rise along the receiving groove until the top or side wall of the glass mold is tightly fitted with the limiting plate 5 to form a clamping limit; after the spray welding is completed, the movable section 62 retracts, the support component 4 descends, and the mold is removed.

[0030] Optionally, a rotation drive component 7 is also included. The rotation drive component 7 is fixedly mounted on the frame 1, and its drive end is connected to the mounting bracket 2. The rotation drive component 7 is used to drive the mounting bracket 2 to reciprocate. Specifically, in this example, the rotation drive component 7 can be a servo motor.

[0031] When the angle of the glass mold needs to be adjusted during the spray welding process, the rotating drive component 7 can drive the mounting frame 2 to swing back and forth around its rotating connection with the frame 1, thereby driving the mounting base 3, the support component 4, and the glass mold on the mounting frame 2 to adjust their angles synchronously. By rotating the drive component 7 to adjust the mold angle, the spray welding gun 17 can evenly cover the surface of the mold to be sprayed.

[0032] Optionally, the mounting base 3 has two sliding grooves 8, which correspond one-to-one with the limiting plate 5. The length direction of the sliding groove 8 is perpendicular to the axis of the mounting rod 18. The limiting plate 5 is slidably disposed in the sliding groove 8 and its position can be adjusted along the length direction of the sliding groove 8 to accommodate glass molds of different widths. The limiting plate 5 has threaded holes arranged opposite to the sliding grooves 8. The limiting plate 5 is provided with locking bolts 9, which are threadedly connected to the threaded holes. The locking bolts 9 can penetrate the limiting plate 5 and abut against the mounting base 3. The locking bolts 9 can be inserted into the sliding grooves 8 and can be loosened and slid within the sliding grooves 8. The mounting base 3 is also provided with guide rails 10, which extend in the same direction as the sliding grooves 8. The guide rails 10 have recesses 101 on their two side walls that are perpendicular to the horizontal plane along their extension direction. The limiting plate 5 has guide grooves that are adapted to the guide rails 10.

[0033] When the position of the limiting plate 5 needs to be adjusted, loosen the locking bolt 9 to allow the limiting plate 5 to slide on the mounting base 3. After sliding the limiting plate 5 to the appropriate position, tighten the locking bolt 9 so that it passes through the limiting plate 5 and abuts against the top surface of the mounting base 3. The friction force fixes the position of the limiting plate 5 in the horizontal direction, preventing it from sliding in the slide groove 8. The engagement between the recess 101 and the inner wall of the guide groove allows the limiting plate 5 to be limited in the vertical direction, preventing it from tilting or shifting in the vertical direction when pressing the glass mold.

[0034] Optionally, the placement groove is V-shaped. The included angle of the V-shaped placement groove can be adjusted according to the outer diameter of common glass molds (such as 60°, 90°, etc.). When the glass mold is placed in the V-shaped groove, the outer wall of the mold is in close contact with the two side walls of the V-shaped groove, forming a two-line support positioning.

[0035] Compared to traditional flat or curved placement slots, V-shaped placement slots can accommodate glass molds with curved outer walls, such as circular and cylindrical molds. They can automatically center the mold, and the V-shaped structure can accommodate circular molds of different diameters, eliminating the need for frequent replacement of the support component 4 and simplifying the operation. During clamping, the semi-cylindrical glass mold is first placed with its curved surface facing down in the V-shaped placement slot. At this point, the curved surface of the mold is tightly fitted to the two walls of the V-shaped slot, and the mold is initially positioned in the horizontal axial direction to prevent displacement. Then, the two limiting plates 5 are slid along the slide 8, aligning the flat sidewalls of the limiting plates 5 with the two edges of the upper end face of the mold. The locking bolts 9 on the limiting plates 5 are tightened to fix their position. Finally, the telescopic component 6 below the mounting base 3 is activated, driving the support component 4 to raise the mold along the receiving slot until the upper end face of the mold is fully abutted against the flat sidewalls of the two limiting plates 5.

[0036] Optionally, it also includes a spray welding device 11, which includes a bracket 12 and a moving component 13. The bracket 12 is mounted on the frame 1; the moving component 13 is disposed on the bracket 12, and a spray welding gun 17 is mounted on the movable end of the moving component 13; the moving component 13 is used to drive the spray welding gun 17 to move.

[0037] Optionally, the moving assembly 13 includes a lifting frame 14, a transverse frame 15, and a longitudinal frame 16. The lifting frame 14 is movably mounted on the support 12 and can move up and down along the height of the support 12, thereby adjusting the vertical position of the welding gun 17. The transverse frame 15 is movably mounted on the lifting frame 14 and can move laterally in the horizontal plane (i.e., along the width of the glass mold). The longitudinal frame 16 is movably mounted on the transverse frame 15 and can move vertically in the horizontal plane, thereby operating the welding gun 17 along the axis of the mold. The lifting frame 14, transverse frame 15, and longitudinal frame 16 form a three-dimensional moving structure, which allows adjustment of the movement path of the welding gun 17 according to the welding requirements, ensuring that all parts of the glass mold are evenly welded, avoiding missed welds or over-welding, and enabling adjustment of the welding gun 17 in three-dimensional space.

[0038] Optionally, each limiting plate 5 has two guide grooves, which are respectively matched with two guide rails 10, and the two guide rails 10 are located at the two ends of the two sliding grooves 8.

[0039] Compared to the cooperation between a single guide rail 10 and the guide groove, the double guide rail 10 structure can further improve the stability of the limiting plate 5 when sliding, prevent the limiting plate 5 from tilting or getting stuck on one side during the movement along the slide groove 8, ensure that the limiting plate 5 always remains horizontal, and fits more tightly with the side wall of the glass mold, avoiding uneven clamping force caused by the tilt of the limiting plate 5, and further ensuring the stability of the mold during the spray welding process.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
