Description

Technical Field

[0001] This utility model relates to the technical field of glass shelf processing equipment, and in particular to a drilling and positioning fixture for glass display cabinet shelves. Background Technology

[0002] In the field of modern commercial display, glass display cases have been widely used due to their transparency, aesthetic appeal, and ability to fully showcase products. As a key component for supporting and displaying products, the design and manufacturing quality of the glass display case's shelves directly affect the overall performance and display effect of the display case.

[0003] Existing glass display case shelves are mostly equipped with metal frames. The metal frames not only effectively distribute the pressure on the glass shelves and significantly reduce the risk of glass breakage, but also facilitate precise connection and fixation with components such as mounting brackets, making shelf installation more convenient and efficient.

[0004] However, in the processing of the metal frame, in addition to opening the buckle groove for connection with the mounting base, it is also necessary to drill holes specifically for the splicing of the frame. The accuracy of these holes is directly related to the accuracy and stability of the frame splicing, which in turn affects the quality and appearance of the entire glass display cabinet shelf. Therefore, when drilling, a fixture must be used to ensure the drilling accuracy.

[0005] Currently, most existing fixtures are pneumatic fixtures. When using these fixtures, to ensure processing efficiency, the usual operation method is to stack multiple sets of outer frames together and then place them between two sets of pneumatic sliders. The pneumatic sliders push the multiple sets of outer frames by pushing them unilaterally or bidirectionally. However, this operation method has obvious drawbacks. Because it is difficult to ensure that the force applied to each set of outer frames is completely uniform during the pushing process, especially when there are many stacked layers, the problem of uneven force is more prominent. Uneven force can cause the top of the outer frame to lift up, which changes the accuracy of the drilling plane. During the drilling process, this change in plane accuracy will directly cause the hole position to deviate, easily resulting in crooked holes. At the same time, the hole diameter may not meet the design requirements, seriously affecting the drilling quality. Poor drilling quality will lead to difficulties in splicing the outer frames, or even failure to splice them properly, requiring rework. This not only consumes a lot of time and labor costs, but also increases production costs, reduces production efficiency, and brings unnecessary economic losses to enterprises. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, the purpose of this utility model is to propose a drilling and positioning fixture for glass display cabinet shelves. This utility model has a reasonable structure and adopts a multi-directional limiting mechanism to accurately fix the shelf frame, effectively preventing displacement and warping, and providing a solid guarantee for high-precision drilling. Compared with traditional fixtures, which suffer from poor drilling quality and low efficiency due to uneven force, this utility model exhibits superior performance, ensuring the stability of drilling quality and the high efficiency of the production process, and its use effect is excellent.

[0008] To achieve the above objectives, this utility model proposes a glass display cabinet shelf drilling and positioning fixture, comprising:

[0009] Seat: Set on the surface of the workbench;

[0010] Cylinder base: evenly and symmetrically arranged on the bottom wall of the opening groove at the top of the base body, and a rotating pressing mechanism is provided at the top;

[0011] First limiting plate: integrally formed and disposed on the side surface of the cylinder seat facing the opening direction of the opening groove;

[0012] Second limiting plate: integrally formed on the inner wall of the opening groove on the side away from the opening direction, and at the same horizontal plane as the first limiting plate;

[0013] Elastic abutment seat and U-shaped part: respectively disposed at the bottom of the first limiting plate and the second limiting plate;

[0014] Plate base: It is vertically slidably connected to the inner side wall of the base body, driven by a cylinder fixedly connected to the bottom wall of the base body, and has a vertical shaft evenly threaded at the top, which is connected to the rotary pressing mechanism.

[0015] In addition, the glass display case shelf drilling and positioning fixture proposed in the above application may also have the following additional technical features:

[0016] Specifically, the cylinder base includes a cylinder portion and an L-shaped plate portion integrally formed on the top of the cylinder portion. The first limiting plate is integrally formed on the vertical section surface of the L-shaped plate portion and together with the L-shaped plate portion, forms a Z-shaped structure.

[0017] Specifically, the rotating pressing mechanism includes a shaft, a pressure plate, a lifting cylinder, a guide groove, and a limiting shaft. The shaft is slidably connected to the inner wall of the L-shaped plate. The pressure plate is threadedly connected to the top of the shaft. The lifting cylinder is slidably connected to the inner wall of the cylinder. The top of the lifting cylinder is fixedly connected to one end of the shaft that penetrates into the cylinder. The bottom of the lifting cylinder is rotatably connected to one end of the vertical shaft that penetrates into the cylinder. The guide groove is formed on the surface of the lifting cylinder. The limiting shaft is threadedly connected to the surface of the cylinder. One end of the limiting shaft penetrates into the cylinder and is slidably connected to the inner wall of the guide groove.

[0018] Specifically, a spherical rubber seat is provided at the bottom of the end of the pressure plate away from the shaft. The rotation angle range of the pressure plate is set between 0° and 180°. After the pressure plate rotates 180°, it is on the same horizontal plane as the top of the first limiting plate and the second limiting plate.

[0019] Specifically, a limiting groove and a limiting block are respectively provided at the corresponding positions on the surface of the plate base and the inner side wall of the base, and the limiting block is slidably connected to the inner wall of the limiting groove.

[0020] Specifically, the surface of the seat is provided with a quick-connect air hose connector, and the output end of the quick-connect air hose connector is connected to the input end of the cylinder.

[0021] Specifically, the bottom of the first limiting plate and the second limiting plate are provided with grooves corresponding to the positions of the elastic abutment seats. The elastic abutment seats are rotatably connected to the inner wall of the grooves and a torsion spring is provided between them. The elastic abutment seats are teardrop-shaped, and one end of the elastic abutment seats away from the central axis extends through the outside of the groove and abuts and is fixed to the top of the shelf frame.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. Ensure drilling accuracy and improve product quality: This fixture is designed for drilling holes in the metal outer frame of glass display cabinet shelves. It effectively avoids the problem of uneven force on the top of the outer frame when stacking and clamping multiple sets of outer frames, which causes changes in the drilling plane accuracy. Through a unique positioning and pressing structure, it ensures that the outer frame is fixed and accurate during the drilling process, making the drilling position accurate and the hole diameter meet the design requirements. This greatly improves the drilling quality, thereby ensuring the accuracy and stability of the outer frame splicing and improving the overall quality and appearance of the glass display cabinet shelves.

[0025] 2. Reasonable structure and stable support: The fixture's base is composed of a cylindrical part and an L-shaped plate integrally formed on the top of the cylindrical part. The first limiting plate is integrally formed on the vertical section surface of the L-shaped plate, forming a Z-shaped structure together with the L-shaped plate. This split-integrated design concept ensures overall strength while providing precise and stable support for the positioning of the shelf frame. During the drilling process, it can withstand the force generated by drilling, reduce the jig's own shaking and deviation, and ensure the stable operation of drilling.

[0026] 3. The ingenious design of the pressing mechanism enhances operational efficiency: The rotary pressing mechanism comprises several key components, including a shaft, pressure plate, lifting cylinder, guide groove, and limiting shaft, which work together to achieve the pressing function. The shaft is slidably connected to the inner wall of the L-shaped plate, and the pressure plate is threaded to the top of the shaft. The lifting cylinder is connected to the vertical shaft and driven by a cylinder to achieve the lifting motion. The cooperation of the guide groove and the limiting shaft restricts the movement trajectory of the lifting cylinder, ensuring the stable operation of the rotary pressing mechanism. The spherical rubber seat at the bottom of the pressure plate is made of highly elastic and wear-resistant rubber material. When it contacts the top of the shelf frame, it provides uniform and gentle pressure, avoiding damage to the top of the shelf frame and ensuring the surface quality of the shelf frame. At the same time, the rotation angle of the pressure plate is set between 0° and 180°. After rotating 180°, it is on the same horizontal plane as the top of the first and second limiting plates, enhancing the compactness and stability of the overall structure, making the fit between the components tighter, and reducing shaking and deviation during operation.

[0027] 4. Multi-directional limiting to ensure shelf frame fixation: The fixture ensures the shelf frame is fixed in position through multiple limiting methods. One side of the shelf frame is attached to the inner wall of the opening slot for lateral positioning. Pushing the shelf frame so that its top contacts the elastic abutment at the bottom of the first or second limiting plate provides stable limiting support as it moves continuously, pressing the elastic abutment into the internal space and maintaining tight contact. Simultaneously, the U-shaped part precisely embeds into the buckle groove of the shelf frame for lateral limiting. Vertical limiting is achieved using the surface of the cylindrical base or the inner wall of the opening slot. The elastic abutment, the first limiting plate, and the second limiting plate work together to limit the top of the shelf frame. This multi-faceted coordination effectively prevents shelf frame displacement and ensures its top does not tilt, providing favorable conditions for drilling operations.

[0028] 5. Easy to operate and improves production efficiency: During operation, the cylinder is driven by the foot control switch, which moves the plate base and the vertical shaft on the plate base vertically upward. At the same time, the rotating pressing mechanism is driven to press down on the top of the shelf frame away from the snap-on groove, further limiting and ensuring the flatness of the top of the shelf frame, improving the accuracy of the drilling plane. This operation method is simple and convenient, reducing the complexity and error of manual operation. It can quickly and accurately complete the positioning and fixing of the shelf frame, greatly shortening the production cycle, improving production efficiency and reducing production costs.

[0029] 6. Adaptable to different working conditions and reduced drill bit cost: The design that the pressure plate rotates to 180° and is on the same horizontal plane as the top of the first and second limiting plates can shorten the length of the drill bit during subsequent drilling operations. The shorter drill bit is more stable when clamped, reducing the possibility of the drill bit breaking during high-speed rotation due to excessive length, thereby reducing the wear cost of the drill bit. At the same time, this design also makes it easy to make flexible adjustments according to different working conditions, improving the versatility and adaptability of the fixture.

[0039] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] The following description, in conjunction with the accompanying drawings, describes the glass display cabinet shelf drilling and positioning fixture according to an embodiment of the present invention.

[0041] like Figures 1-6 As shown, an embodiment of the present invention provides a glass display case shelf drilling and positioning fixture, comprising:

[0042] Seat 1: Set on the surface of the workbench;

[0043] Cylinder base 2: It is evenly and symmetrically arranged on the bottom wall of the opening groove 11 at the top of the base body 1, and a rotating pressing mechanism 3 is provided at the top;

[0044] First limiting plate 4: integrally formed and set on the side surface of cylinder seat 2 facing the opening direction of opening slot 11;

[0045] Second limiting plate 5: integrally formed and disposed on the inner wall of the opening groove 11 away from the opening direction, and at the same horizontal plane as the first limiting plate 4;

[0046] Elastic abutment seat 6 and U-shaped part 7: respectively disposed at the bottom of the first limiting plate 4 and the second limiting plate 5;

[0047] Plate base 8: It is vertically slidably connected to the inner wall of the base body 1 and driven by the cylinder 9 which is fixedly connected to the bottom wall of the base body 1. The top is evenly threaded with a vertical shaft 10 and connected to the rotating pressing mechanism 3.

[0048] It should be noted that, in this embodiment, the height between the bottom of the first limiting plate 4 and the second limiting plate 5 and the inner bottom wall of the opening groove 11 is equal to the height of the shelf frame 500, and the length of the first limiting plate 4 and the second limiting plate 5 overlapping the top of the shelf frame 500 is less than half the width of the shelf frame 500.

[0049] It should also be noted that the U-shaped part 7 described in this embodiment corresponds to the position of the fastener groove on the shelf frame 500, and their external dimensions are compatible.

[0050] It should also be noted that the two sets of cylinder seats 2 near the opening direction of the opening slot 11 are not provided with the first limiting plate 4.

[0051] It should also be noted that the end of the opening slot 11 away from the opening direction is the work station end, and the end of the opening slot 11 facing the opening direction faces the inside of the worktable. This placement facilitates the subsequent blowing of waste into the machine, and the waste is collected uniformly by the waste collection mechanism inside the machine.

[0052] It should also be noted that cylinder 9 is driven by a foot-operated control switch (not shown in the figure).

[0053] Specifically, this utility model has a reasonable structure and adopts a multi-directional limiting mechanism to accurately fix the shelf frame 500, effectively preventing displacement and warping, providing a solid guarantee for high-precision drilling. Compared with the shortcomings of traditional fixtures, such as poor drilling quality and low efficiency caused by uneven force, this utility model exhibits excellent performance, ensuring the stability of drilling quality and the high efficiency of the production process, and the effect of use is excellent.

[0054] The operating steps of the glass display cabinet shelf drilling and positioning fixture are as follows: First, position and install the shelf frame 500 by attaching one side of the shelf frame 500 to the inner wall of one side of the opening groove 11, thereby achieving single-sided positioning of the shelf in the horizontal direction. Then, push the shelf frame 500 towards the side of the opening groove 11 away from the opening direction. When the shelf frame 500 abuts against the surface of the cylinder base 2, it is below the first limiting plate 4. If the shelf frame 500 abuts against the inner wall of the opening groove 11 away from the opening direction, it is below the second limiting plate 5. During the process of pushing the shelf frame 500, its top... It will first contact the elastic abutment seat 6 at the bottom of the first limiting plate 4 or the second limiting plate 5. As the shelf frame 500 continues to move, the elastic abutment seat 6 will be gradually pressed into the internal space of the first limiting plate 4 and the second limiting plate 5 due to the squeezing action of the shelf frame 500. Furthermore, throughout the entire subsequent operation, the elastic abutment seat 6 can always maintain close contact with the top of the shelf frame 500, providing stable and continuous limiting support for the shelf frame 500. Then, the U-shaped part 7 will be precisely embedded in the buckle groove of the shelf frame 500. When the shelf frame 500 is in contact with the surface of the cylinder seat 2 or the opening groove 1, When the inner wall away from the opening direction abuts against and stops moving, the multi-directional limiting operation is completed: the U-shaped part 7 and the fastener groove cooperate to limit the shelf frame 500 laterally; the surface of the cylindrical base 2 or the inner wall of the opening groove 11 is used to limit the shelf frame 500 vertically; and the top of the shelf frame 500 is limited by the coordinated action of the elastic abutment 6, the first limiting plate 4, and the second limiting plate 5. Through the coordinated action of the above multiple aspects, it can be ensured that the shelf frame 500 is fixed and accurate in position after being released from the hand, effectively preventing its displacement, while ensuring that its top does not tilt up, thus completing the shelf frame operation. After the frame 500 is positioned, the next step of pressing and fixing is performed. The cylinder 9 is driven by the foot control switch. After the cylinder 9 is started, it will drive the plate base 8 and the vertical shaft 10 on the plate base 8 to move vertically upward. Since the vertical shaft 10 is connected to the rotating pressing mechanism 3, when the vertical shaft 10 rises, it will drive the rotating pressing mechanism 3 to operate simultaneously, pressing down on the top of the shelf frame 500 away from the buckle groove. This operation not only further limits the shelf frame 500, but also effectively ensures the flatness of the top of the shelf frame 500, thereby further improving the accuracy of the drilling plane and achieving good results.

[0055] In one embodiment of this utility model, such as Figure 3 As shown, the cylinder base 2 includes a cylinder portion 21 and an L-shaped plate portion 22 integrally formed on the top of the cylinder portion 21. The first limiting plate 4 is integrally formed on the vertical section surface of the L-shaped plate portion 22 and together with the L-shaped plate portion 22, forms a Z-shaped structure.

[0056] Specifically, the cylinder base 2 adopts a split design concept, but is manufactured as a whole. It consists of a cylinder 21 and an L-shaped plate 22 integrally formed on the top of the cylinder 21. The first limiting plate 4 is also integrally formed on the vertical section surface of the L-shaped plate 22. The first limiting plate 4 and the L-shaped plate 22 cooperate with each other to form a Z-shaped structure. This structure ensures the overall strength while providing precise and stable support for the positioning of the shelf frame 500, resulting in good performance.

[0057] In one embodiment of this utility model, such as Figure 3 As shown, the rotating pressing mechanism 3 includes a shaft 31, a pressure plate 32, a lifting cylinder 33, a guide groove 34, and a limiting shaft 35. The shaft 31 is slidably connected to the inner wall of the L-shaped plate portion 22. The pressure plate 32 is threadedly connected to the top of the shaft 31. The lifting cylinder 33 is slidably connected to the inner wall of the cylinder portion 21. The top of the lifting cylinder 33 is fixedly connected to one end of the shaft 31 that penetrates into the cylinder portion 21. The bottom of the lifting cylinder 33 is rotatably connected to one end of the vertical shaft 10 that penetrates into the cylinder portion 21. The guide groove 34 is formed on the surface of the lifting cylinder 33. The limiting shaft 35 is threadedly connected to the surface of the cylinder portion 21. One end of the limiting shaft 35 penetrates into the cylinder portion 21 and is slidably connected to the inner wall of the guide groove 34.

[0058] It should be noted that when the pressure plate 32 described in this embodiment is not rotated, the end face of the end away from the shaft 31 does not exceed the end face of the first limiting plate 4 away from the shaft 31. This design facilitates the placement of the shelf frame 500.

[0059] Specifically, the rotary pressing mechanism 3 comprises several key components that cooperate to achieve the pressing function. The shaft 31 is mounted on the inner wall of the L-shaped plate 22 and can slide along the inner wall, providing basic support for the movement of the entire mechanism. The pressure plate 32 is fixed to the top of the shaft 31 by a threaded connection. When the shaft 31 moves, the pressure plate 32 moves accordingly, thereby pressing down on the top of the shelf frame 500. The lifting cylinder 33 is located inside the cylinder 21 and is slidably connected to the inner wall of the cylinder 21. Its top is connected to the end of the shaft 31 that extends into the cylinder 21, and its bottom is connected to the vertical shaft 10 that extends into the cylinder 21. One end of the cylindrical part 21 is rotatably connected, so that when the vertical shaft 10 moves up and down, it will drive the lifting column cylinder 33 to rise and fall together, thereby driving the shaft 31 and the pressure plate 32 to move. A guide groove 34 is provided on the surface of the lifting column cylinder 33. The limiting shaft 35 is threadedly connected to the surface of the cylindrical part 21, and one end extends into the cylindrical part 21 and slides in connection with the inner wall of the guide groove 34. The cooperation between the limiting shaft 35 and the guide groove 34 can limit the movement trajectory of the lifting column cylinder 33, prevent it from moving excessively or deviating, and at the same time ensure that the lifting column cylinder 33 can rotate according to the preset rotation angle, ensuring the stable operation of the rotating pressing mechanism 3.

[0060] In one embodiment of this utility model, such as Figures 1-2 and Figure 4 As shown, a spherical rubber seat 36 is provided at the bottom of the end of the pressure plate 32 away from the shaft 31. The rotation angle range of the pressure plate 32 is set between 0° and 180°. After the pressure plate 32 rotates 180°, it is on the same horizontal plane as the top of the first limiting plate 4 and the second limiting plate 5.

[0061] Specifically, a spherical rubber seat 36 is specially configured at the bottom of the end of the pressure plate 32 away from the shaft 31. This spherical rubber seat 36 is made of rubber material with high elasticity and good wear resistance. When it contacts the top of the shelf frame 500, it can provide uniform and gentle pressure due to its own elasticity, avoiding scratches, indentations, or other damage to the top of the shelf frame 500 caused by excessive or uneven pressure, thus ensuring the surface quality of the shelf frame 500. The rotation angle range of the pressure plate 32 is precisely set between 0° and 180°. When the pressure plate 32 rotates to 180°... When positioned, it will be on the same horizontal plane as the top of the first limiting plate 4 and the second limiting plate 5. This design has multiple advantages. From a structural point of view, it enhances the compactness and stability of the overall structure, makes the fit between various components tighter, and reduces shaking and deviation during operation. From a processing operation perspective, it can shorten the length of the drill bit during subsequent drilling operations, making the drill bit more stable when clamped, reducing the possibility of the drill bit breaking during high-speed rotation due to excessive length, thereby reducing the wear cost of the drill bit and improving the accuracy and quality of drilling.

[0062] In one embodiment of this utility model, such as Figure 1 As shown, a limiting groove 81 and a limiting block are respectively provided on the surface of the plate base 8 and the inner side wall of the base body 1, and the limiting block is slidably connected to the inner wall of the limiting groove 81.

[0063] Specifically, a limiting groove 81 and a limiting block are carefully set at the positions corresponding to the inner side wall of the base 1 on the surface of the plate base 8. The limiting block and the inner wall of the limiting groove 81 are slidably connected. This design can ensure that the plate base 8 moves smoothly and accurately along a predetermined trajectory inside the base 1, effectively avoiding the plate base 8 from deviating or shaking during the movement, thereby improving the stability and reliability of the entire device.

[0064] In one embodiment of this utility model, such as Figure 2 As shown, a quick-connector 100 for the air hose is provided on the surface of the seat 1, and the output end of the quick-connector 100 is connected to the input end of the cylinder 9.

[0065] Specifically, the surface of the base 1 is specially provided with a quick-connect air pipe 100. The output end of the quick-connect air pipe 100 is stably connected to the input end of the cylinder 9, thereby establishing a reliable gas transmission channel to ensure that the cylinder 9 can stably and accurately receive power from the air source, providing a strong guarantee for the normal operation of the entire device.

[0066] In one embodiment of this utility model, such as Figure 3 As shown, the bottom of the first limiting plate 4 and the second limiting plate 5 are respectively provided with grooves corresponding to the position of the elastic abutment seat 6. The elastic abutment seat 6 is rotatably connected to the inner wall of the groove, and a torsion spring 61 is provided between the elastic abutment seat 6 and the inner wall of the groove. The elastic abutment seat 6 is teardrop-shaped, and one end of the elastic abutment seat 6 away from the central axis passes through the outside of the groove and abuts and is fixed to the top of the layer plate frame 500.

[0067] Specifically, grooves (not shown in the figure) are opened at corresponding positions at the bottom of the first limiting plate 4 and the second limiting plate 5. The elastic abutment seat 6 is rotatably connected to the inner wall of the groove and is equipped with a torsion spring 61. This design allows the elastic abutment seat 6 to rotate flexibly. The teardrop-shaped appearance, combined with the elastic effect of the torsion spring 61, allows the end away from the central axis to pass through the groove tightly and stably, and abut against and fix to the top of the shelf frame 500. During drilling, it can effectively prevent the shelf frame 500 from shifting or lifting, greatly improve the drilling accuracy, efficiently solve the problem of poor drilling quality caused by uneven force in existing fixtures, improve production efficiency, and has a good effect.

[0068] In summary, the glass display cabinet shelf drilling positioning fixture of this utility model has a reasonable structure and adopts a multi-directional limiting mechanism to accurately fix the shelf frame by 500°, effectively preventing displacement and warping. It provides a solid guarantee for high-precision drilling. Compared with traditional fixtures, which suffer from poor drilling quality and low efficiency due to uneven force, this utility model exhibits superior performance, ensuring the stability of drilling quality and the high efficiency of the production process, and its use effect is excellent.
