Description
Technical Field
[0001] This utility model relates to the field of tilting tables, and in particular to a self-locking and durable tilting table structure. Background Technology
[0002] In the traditional die-forming industry, after the die is installed on the die-forming machine, it often needs to be repaired or replaced. Before repairing or replacing the die, the upper die needs to be opened, that is, the upper die needs to be rotated 180 degrees. Due to the large size of the upper die, weighing over 100 tons, lifting and rotating the upper die requires specialized die-turning equipment. To facilitate die repair, if the upper die is to be rotated 180 degrees, three mechanisms need to be added to the equipment: a hinge mechanism, a turning mechanism, and a locking mechanism. The traditional locking mechanism is similar to a door bolt. Because the upper worktable needs to be completely fitted with the slide, the drawbacks of the die-turning machines on the market that use hydraulic cylinder pins and guide sleeves to lock the upper worktable and slide have gradually become apparent. As the weight of the die increases and the size of the worktable increases, the hydraulic cylinder pin and guide sleeve structure for locking the upper worktable and slide is prone to wear of the guide sleeve and pin, resulting in the upper worktable and slide not being able to fit completely or a gap appearing after the upper worktable and slide are closed, making the upper worktable not horizontal, thus affecting the accuracy of die-forming. Furthermore, when a large mold is installed on the workbench, it is prone to deformation, resulting in the mechanism's movement being unsmooth. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a self-locking and durable structure for a tilting table.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The self-locking durable structure of the tilting table includes a slide table, on which a worktable tilting drive device is rotatably mounted. The bottom of the slide table is connected to and mounted on a worktable via a hinge. The output end of the worktable tilting drive device is rotatably connected to the top of the worktable. A first locking seat, a second locking seat, a locking mechanism, a third locking seat, and a fourth locking seat are sequentially provided on one side of the slide table. A first locking component and a second locking component are respectively installed on the top of one end of the worktable. Several parallel positioning grooves are provided on the bottom surface of the same end of the worktable. Several positioning grooves are perpendicular to one side of the worktable and penetrate one side of the worktable. Several upper mold sensing components and several side reference components are installed on the bottom of the worktable. Several upper mold sensing components and several side reference components are respectively installed on the corresponding positioning grooves.
[0005] Preferably, the first locking assembly includes a connecting screw, a hollow adjusting screw, a locking pad, a movable locking seat, and a first mounting seat. The movable locking seat is mounted on the top of the first mounting seat and has a first pin hole that extends laterally through the first mounting seat. The hollow adjusting screw extends longitudinally through the top of the movable locking seat and is threadedly connected to the top of the movable locking seat. The locking pad is slidably mounted in the first pin hole. The connecting screw is mounted in the hole of the hollow adjusting screw and is threadedly connected to the locking pad. The locking pad includes a pad body, with limiting blocks integrally formed extending upward from both ends of the pad body. Limiting grooves are recessed upward from both sides of the top wall of the first pin hole, and the shape of the limiting blocks matches the shape of the limiting grooves.
[0006] Specifically, the locking mechanism includes a first pin, a second pin, a first rod, a second rod, and a pin translation drive device. The first pin and the second pin are respectively connected and installed to the two output ends of the pin translation drive device through the first rod and the second rod.
[0007] Specifically, the first pin includes a pin body, the top of which is provided with an upper inclined surface, and the upper inclined surface is provided with a series of grooves for receiving grease. The structure of the second pin is the same as that of the first pin.
[0008] Specifically, the bottom of the locking pad has a downward slope, which is parallel to the upward slope of the first pin. The structure and working principle of the second locking assembly are the same as those of the first locking assembly.
[0009] Specifically, the first locking seat, the second locking seat, the third locking seat, and the fourth locking seat are all provided with a second pin hole. The second pin holes of the first locking seat and the second locking seat are for the first pin to pass through, and the second pin holes of the third locking seat and the fourth locking seat are for the second pin to pass through. The first locking seat and the fourth locking seat are respectively provided with a first mounting plate and a second mounting plate on their opposite sides. The first mounting plate and the second mounting plate are respectively equipped with a first photoelectric sensor and a second photoelectric sensor.
[0010] Specifically, a first sensing plate and a second sensing plate are respectively installed on the end of the first pin and the second pin near the pin translation drive device. A third mounting plate and a fourth mounting plate are installed on one side of the slide table. A third photoelectric sensor and a fourth photoelectric sensor are respectively installed on the third mounting plate and the fourth mounting plate. The third photoelectric sensor and the fourth photoelectric sensor are located between the first sensing plate and the second sensing plate. The third photoelectric sensor is opposite to the first sensing plate, and the fourth photoelectric sensor is opposite to the second sensing plate.
[0011] Preferably, the upper mold sensing assembly includes a second mounting base, a first hexagon socket screw, and a fifth photoelectric sensor. The second mounting base is fixedly mounted on the positioning slot of the worktable by the first hexagon socket screw, and the fifth photoelectric sensor is installed in the second mounting base and is used to sense whether the upper mold is installed in place.
[0012] Preferably, the side reference assembly includes a third mounting base, a second hexagon socket screw, and a third hexagon socket screw. The third mounting base is fixedly mounted on the positioning groove of the worktable by the second hexagon socket screw, and the third hexagon socket screw is horizontally mounted on the third mounting base and is used to adjust the lateral reference position of the upper mold.
[0013] Preferably, a controller is provided that is connected to the locking mechanism, the upper mold sensing component and the worktable flipping drive device, etc. The controller is a PLC programmable logic controller, which can be a programmable logic controller of model XDS-40T-D, but is not limited thereto.
[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. The mechanism comprises a first locking seat, a second locking seat, a locking mechanism, a third locking seat, and a fourth locking seat sequentially arranged on one side of the slide table, and a first locking assembly and a second locking assembly respectively installed on the top of one end of the worktable. When the worktable is driven by the worktable tilting drive device to fit against the slide table, the first locking assembly is embedded between the first and second locking seats, and the second locking assembly is embedded between the third and fourth locking seats. A first pin at one end of the locking mechanism passes sequentially through the first pin hole of the first locking assembly and the second pin hole of the first locking seat in the second pin hole of the second locking seat. A second pin at the other end of the locking mechanism passes sequentially through the first pin hole of the second locking assembly and the second pin hole of the fourth locking seat in the second pin hole of the third locking seat, ensuring a secure and tight fit between the worktable and the slide table. The locking mechanism adopts a wedge-shaped structure. Furthermore, by designing the structures of the first and second locking components separately, the height of the locking pad within the first pin hole can be adjusted by twisting the hollow adjusting screw. This allows for adjustable height of the locking pad, enabling the constant adjustment of the fit between the worktable and the slide to ensure mold closing accuracy. This not only improves assembly speed by over 30%, but also effectively solves the problems of existing mold-changing machines that use hydraulic cylinder pins and guide sleeves to lock the worktable and slide. These problems often result in wear and tear on the guide sleeves and pins, leading to incomplete fit between the worktable and slide, or gaps after closure, affecting mold closing accuracy. Additionally, existing mold-changing machines often experience deformation when large molds are installed on the worktable, causing uneven mechanism operation.
[0015] 2. By designing the structure of the locking pad and the first or second pin, the annular groove on the upper inclined surface of the first or second pin contains grease. The grease provides lubrication for the sliding of the first or second pin and the locking pad, avoiding dry friction damage between the first or second pin and the locking pad, and improving service life.
[0016] 3. To address the issue of insufficient preload when fixing the worktable and upper mold, several side reference components and several upper mold sensing components are installed on the bottom of the worktable. The side reference components can provide lateral restraint for upper molds of different sizes installed on the bottom of the worktable, and the upper mold sensing components can detect that the upper mold is in place before the equipment can start working. This prevents the worktable from flipping due to the upper mold not being securely installed on the worktable, thus greatly improving production safety. Attached Figure Description

[0028] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0030] Reference Figure 1 and Figure 2 As shown, this utility model discloses a self-locking and durable tilting table structure, including a slide table 1. A worktable tilting drive device 2 is rotatably mounted on the slide table 1. A worktable 4 is mounted on the bottom of the slide table 1 via a hinge 3. The output end of the worktable tilting drive device 2 is rotatably connected to the top of the worktable 4. One side of the slide table 1 is sequentially provided with a first locking seat 51, a second locking seat 52, a locking mechanism 6, a third locking seat 53, and a fourth locking seat 54. A first locking assembly 71 and a second locking assembly 72 are respectively mounted on the top of one end of the worktable 4. Several parallel positioning grooves 8 are provided on the bottom surface of the same end of the worktable 4. The positioning grooves 8 are perpendicular to one side of the worktable 4 and penetrate one side of the worktable 4. Several upper mold sensing components 9 and several side reference components 10 are mounted on the bottom of the worktable 4, and the upper mold sensing components 9 and the side reference components 10 are respectively mounted on the corresponding positioning grooves 8. Rollers 11 are respectively mounted on the two sides of the worktable 4.
[0031] By adopting the above technical solution, the worktable flipping drive device 2 drives the worktable 4 to flip upward around the hinge 3, and the worktable 4 closes with the slide 1. The first locking component 71 is inserted between the first locking seat 51 and the second locking seat 52, and the second locking component 72 is inserted between the third locking seat 53 and the fourth locking seat 54. The locking mechanism 6 locks the first locking component 71 on the first locking seat 51 and the second locking seat 52, and locks the second locking component 72 on the third locking seat 53 and the fourth locking seat 54, respectively, so as to firmly lock the worktable 4 to the bottom of the slide 1, so as to ensure high mold closing accuracy and that the worktable 4 will not deform when a large mold is installed. This solves the problem that the worktable and slide of the existing mold flipping machine on the market are prone to not being able to fit completely or there is a gap after the worktable and slide are closed, which affects the mold closing accuracy and causes deformation when a large mold is installed on the worktable, resulting in unsmooth mechanism operation. The side reference component 10 provides lateral positioning for the upper mold installed at the bottom of the workbench 4. The upper mold sensing component 9 detects whether the upper mold is properly installed at the bottom of the workbench 4. Only after the upper mold is properly installed on the workbench 4 and the upper mold sensing component 9 detects the upper mold can the mold be flipped, thus preventing the upper mold from falling off due to improper installation and ensuring production safety.
[0032] In this embodiment, the worktable tilting drive device 2 is preferably configured as a tilting hydraulic cylinder. The upper mold can be fixedly installed on the bottom of the worktable 4 by clamps or screws. In another embodiment, the worktable 4 can also be configured as an electro-permanent magnet chuck to fix the upper mold to its bottom by magnetic attraction, so it is not limited to this. The above-mentioned methods of fixing the upper mold are all common knowledge and will not be explained in detail here.
[0033] Reference Figures 3 to 5 As shown, the first locking assembly 71 includes a connecting screw 711, a hollow adjusting screw 712, a locking pad 713, a movable locking seat 714, and a first mounting seat 715. The movable locking seat 714 is mounted on the top of the first mounting seat 715 and has a first pin hole 716 extending laterally through the first mounting seat 715. The hollow adjusting screw 712 extends longitudinally through the top of the movable locking seat 714 and is threadedly connected to the top of the movable locking seat 714. The locking pad 713 is slidably mounted in the first pin hole 716. The connecting screw 711 is mounted in the hole of the hollow adjusting screw 712 and is threadedly connected to the locking pad 713.
[0034] Reference Figure 4 , Figures 6 to 7 As shown, the locking pad 713 includes a pad body 7131. Both ends of the pad body 7131 extend upward and are integrally formed with limiting blocks 7132. The two sides of the top wall of the first pin hole 716 are respectively provided with limiting grooves 717 recessed upward. The shape of the limiting block 7132 is adapted to the shape of the limiting groove 717.
[0035] By adopting the above technical solution, the locking washer 713 is installed at the bottom of the hollow adjusting screw 712 via the connecting screw 711. The hollow adjusting screw 712 is threadedly connected to the movable locking seat 714. Twisting the hollow adjusting screw 712 can adjust the height of the locking washer 713 within the first pin hole 716. Before adjusting the height, first twist the connecting screw 711 to loosen the tight contact between the locking washer 713 and the bottom of the hollow adjusting screw 712. Twisting the hollow adjusting screw 712 further adjusts the locking washer 713 to a suitable height. Then twist the connecting screw 711 to... The locking pad 713 is locked to the bottom of the hollow adjusting screw 712. The two limiting blocks 7132 of the locking pad 713 cooperate with the two limiting grooves 717 of the movable locking seat 714 to guide and limit the lifting and sliding of the locking pad 713. This not only prevents the locking pad 713 from shifting laterally during the lifting and sliding process, but also prevents the first pin 61 from being inserted into the first pin hole 716 and pushing the locking pad 713 out of the movable locking seat 714. This improves the quality stability of the first locking assembly 71 and also improves the stability of the slide 1 locking the worktable 4 through the locking mechanism 6.
[0036] Reference Figure 8 and Figure 9 As shown, the locking mechanism 6 includes a first pin 61, a second pin 62, a first pin 63, a second pin 64, and a pin translation drive device 65. The first pin 61 and the second pin 62 are respectively connected and installed to the two output ends of the pin translation drive device 65 through the first pin 63 and the second pin 64.
[0037] By adopting the above technical solution, the two output ends of the pin translation drive device 65 respectively drive the first pin 61 and the second pin 62 to move closer to or further away from each other.
[0038] In this embodiment, the pin translation drive device 65 is preferably configured as a hydraulic cylinder.
[0039] Reference Figure 4 and Figure 5 As shown, the first pin 61 includes a pin body 611, the top of the pin body 611 is provided with an upper inclined surface 612, and the upper inclined surface 612 is provided with a continuous groove 613 for accommodating grease; the structure of the second pin 62 is the same as that of the first pin 61.
[0040] By adopting the above technical solution, the entire locking mechanism 6 adopts a wedge-shaped structure and cooperates with the first locking component 71 and the second locking component 72, ensuring high mold closing accuracy. This solves the problem of poor mold closing accuracy caused by the easy wear of guide sleeves and pins in the hydraulic cylinder pin and guide sleeve structure used by the mold flipping machine on the market to lock the worktable and slide.
[0041] Reference Figure 4 As shown, the bottom of the locking pad 713 has a lower inclined surface 718, which is parallel to the upper inclined surface 612 of the first pin 61. The structure and working principle of the second locking assembly 72 are the same as those of the first locking assembly 71.
[0042] By adopting the above technical solution, the annular groove 613 of the upper inclined surface 612 of the first pin 61 contains grease. The first pin 61 is inserted into the first pin hole 716 of the movable locking seat 714. The upper inclined surface 612 of the first pin 61 abuts against the lower inclined surface 718 of the locking pad 713. The first pin 61 slides on the lower inclined surface 718 of the locking pad 713 and supports the locking pad 713. The grease provides lubrication for the first pin 61 and the locking pad 713, avoiding the problem that the first pin 61 and the locking pad 713 are damaged by dry friction, which would cause the worktable 4 and the slide table 1 to not fit completely or to form a gap after the worktable 4 and the slide table 1 are closed, thus affecting the mold closing accuracy. It also greatly improves the service life.
[0043] Reference Figure 8 and Figure 9 As shown, the first locking seat 51, the second locking seat 52, the third locking seat 53 and the fourth locking seat 54 are all provided with a second pin hole 511. The second pin hole 511 of the first locking seat 51 and the second locking seat 52 is for the first pin 61 to pass through, and the second pin hole 511 of the third locking seat 53 and the fourth locking seat 54 is for the second pin 62 to pass through. The first mounting plate 512 and the second mounting plate 513 are respectively provided on the two opposite sides of the first locking seat 51 and the fourth locking seat 54. The first photoelectric sensor 514 and the second photoelectric sensor 515 are respectively mounted on the first mounting plate 512 and the second mounting plate 513.
[0044] By adopting the above technical solution, when locking the worktable 4, the two output ends of the pin translation drive device 65 drive the first pin 61 and the second pin 62 to move respectively. The first pin 61 is in the second pin hole 511 of the second locking seat 52 and passes through the first pin hole 716 of the first locking assembly 71 and the second pin hole 511 of the first locking seat 51 in sequence. At the same time, the second pin 62 is in the second pin hole 511 of the third locking seat 53 and passes through the first pin hole 716 of the second locking assembly 72 and the second pin hole 511 of the fourth locking seat 54 in sequence. The first photoelectric sensor 514 and the second photoelectric sensor 515 detect the first pin 61 and the second pin 62 respectively. The first pin 61 and the second pin 62 lock the first locking assembly 71 and the second locking assembly 72 into place respectively, realizing the locking operation of the slide table 1 on the worktable 4.
[0045] Reference Figure 8 and Figure 9 As shown, a first sensing plate 516 and a second sensing plate 517 are respectively installed on one end of the first pin 61 and the second pin 62 near the pin translation drive device 65. A third mounting plate 518 and a fourth mounting plate 519 are installed on one side of the slide table 1. A third photoelectric sensor 510 and a fourth photoelectric sensor 5101 are respectively installed on the third mounting plate 518 and the fourth mounting plate 519. The third photoelectric sensor 510 and the fourth photoelectric sensor 5101 are located between the first sensing plate 516 and the second sensing plate 517. The third photoelectric sensor 510 is opposite to the first sensing plate 516, and the fourth photoelectric sensor 5101 is opposite to the second sensing plate 517.
[0046] By adopting the above technical solution, when unlocking the worktable 4, the first pin 61 sequentially exits the second pin hole 511 of the first locking seat 51 and the first pin hole 716 of the first locking component 71, while the second pin 62 sequentially exits the second pin hole 511 of the fourth locking seat 54 and the first pin hole 716 of the second locking component 72, thereby realizing the unlocking of the worktable 4 by the slide table 1.
[0047] Reference Figure 10 As shown, the upper mold sensing component 9 includes a second mounting base 91, a first hexagon socket screw 92, and a fifth photoelectric sensor 93. The second mounting base 91 is fixedly mounted on the corresponding positioning slot 8 of the worktable 4 by the first hexagon socket screw 92. The fifth photoelectric sensor 93 is installed in the second mounting base 91 and is used to sense whether the upper mold is installed in place.
[0048] By adopting the above technical solution, the mold flipping machine can start to flip the worktable 4 only after the fourth photoelectric sensor 5101 senses that the upper mold is installed in place, thus avoiding the occurrence of safety accidents caused by the upper mold not being installed securely on the worktable 4 and flipping the worktable 4.
[0049] Reference Figure 10 As shown, the side reference assembly 10 includes a third mounting base 101, a second hexagon socket screw 102, and a third hexagon socket screw 103. The third mounting base 101 is fixedly mounted on the corresponding positioning groove 8 of the worktable 4 by the second hexagon socket screw 102. The third hexagon socket screw 103 is horizontally mounted on the third mounting base 101 and is used to adjust the lateral reference position of the upper mold.
[0050] By adopting the above technical solution, the third internal hex screw 103 adjusts the upper mold to the lateral reference position of the worktable 4 and limits the upper mold to a lateral position, thus preventing the upper mold from slipping sideways on the worktable 4 and causing a safety accident.
[0051] The above embodiments are merely examples of this utility model and are not intended to limit the implementation and scope of this utility model. All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
