Description

Technical Field

[0001] This utility model belongs to the field of metering box manufacturing technology, and in particular relates to a limiting groove pad for one-time molding of metering boxes. Background Technology

[0002] As a key equipment enclosure in public utilities such as electricity, water, and gas, the structural strength, sealing performance, and positioning accuracy of internal components of the metering box directly affect the long-term stability and safety of the metering instruments. The limiting groove pad, as the core positioning structure inside the metering box, functions to provide precise installation reference positions for electrical components, sealing components, or sensor modules, while its groove design achieves mechanical limiting and stress dispersion. The metal pad, as a critical positioning component of the box structure, directly affects the assembly quality of the metering box due to its forming accuracy.

[0003] Traditional molds mostly use a fixed limiting groove structure, which has two major problems: First, the mold needs to be changed frequently for different specifications of pads, resulting in low production efficiency and increased costs; Second, the clamping mechanism with single-axis manual adjustment is difficult to achieve precise positioning in both XY directions, which can easily cause the sheet metal to shift during the pressing process, resulting in out-of-tolerance dimensions of the molded parts. Moreover, multiple sets of positioning pins need to be manually calibrated during the installation process, which is time-consuming and not conducive to large-scale production.

[0004] To address these issues, we provide a limiting groove pad for one-piece molding of a metering box. Utility Model Content

[0005] The purpose of this utility model is to provide a limiting groove pad for one-time molding of a metering box. By cooperating with the X-axis limiting mechanism and the Y-axis limiting mechanism, the problem of inconvenient installation and inability to adaptively limit the limiting groove pad for one-time molding of a metering box in the prior art is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model is a limiting groove pad for one-time molding of a metering box, including an upper mold and a lower mold. The lower mold has a groove on its top and a pad body is provided on its top.

[0008] The inner cavity of the groove is provided with an X-axis limiting mechanism, which includes a first threaded rod rotatably connected to the inner cavity of the groove through a bearing seat, a threaded sleeve threadedly connected to the surface of the first threaded rod, and a first clamping plate fixedly connected to the surface of the threaded sleeve.

[0009] The first clamping plate has a Y-axis limiting mechanism in its inner cavity. The Y-axis limiting mechanism includes a push plate disposed in the inner cavity of the first clamping plate, a fixing rod fixedly connected to one side of the push plate, and a second clamping plate fixedly connected to the other end of the fixing rod.

[0010] The present invention is further configured such that the surface of the first threaded rod is provided with positive and negative thread sections with opposite directions of rotation, and the other end of the first threaded rod extends through to the outside of the lower mold and is fixedly connected to a first bolt head. The clamping distance can be adjusted manually by rotating the first bolt head, and can be adjusted according to different sizes of the pad body. The design of the positive and negative thread sections of the first threaded rod can ensure that the two threaded sleeves move towards each other.

[0011] The present invention is further configured such that the first clamping plate is convex in shape, and the top of the lower mold is provided with a limiting groove adapted to the first clamping plate. The vertical part of the first clamping plate passes through the limiting groove at the top of the groove and is clearance-fitted with it to ensure the stability of the axial movement of the first clamping plate.

[0012] The present invention is further configured such that a spring is sleeved on the surface of the fixing rod, one end of the spring is fixedly connected to the inner side of the first clamping plate, and the other end of the spring is fixedly connected to one side of the push plate.

[0013] The present invention is further configured such that a threaded hole is provided on one side of the lower mold, and a second threaded rod is threadedly connected to the inner cavity of the threaded hole, and the threaded hole and the second threaded rod cooperate with each other.

[0014] The present invention is further configured such that a second bolt head is fixedly connected to one end of the second threaded rod, and a drive plate is rotatably connected to the other end of the second threaded rod through a bearing seat. The drive plate is axially fed by rotating the threaded rod. The drive plate drives the push plate to move through the slide frame. The push plate drives the second clamping plate to move through the fixed rod, thereby achieving secondary positioning.

[0015] The present invention is further configured such that sliding frames are slidably connected to both sides of the drive plate, and one side of the sliding frame is fixedly connected to one side of the push plate. During the movement of the two first clamping plates, the drive plate and the sliding frame drive the push plate on the same side to move, thereby realizing the linkage movement of the two second clamping plates on the same side and improving the limiting effect.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model achieves three-dimensional spatial positioning of the pad by cooperating with the X / Y axis linkage limiting mechanism and the bidirectional first threaded rod. In the X-axis direction, the positive and negative threads drive the synchronous movement of the two clamping plates. In the Y-axis direction, the threaded rod advances and the spring returns to form an elastic clamping system, which can quickly adapt to pads of different specifications, with low adjustment time. The sliding fit between the convex first clamping plate and the limiting groove has high precision. With the spring preload compensation mechanism, the clamping surface is evenly stressed.

[0018] 2. This utility model uses a sliding connection design between the drive plate and the slide frame to enable the second clamping plates on both sides to be driven simultaneously by a single tightening of the second bolt head, thus achieving rapid clamping.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1-5 This utility model is a limiting groove pad for one-time molding of a metering box, including an upper mold 1 and a lower mold 2. The lower mold 2 has a groove 3 on its top and a pad body 4 on its top. The groove 3 has an X-axis limiting mechanism, which includes a first threaded rod 5 rotatably connected to the groove 3 through a bearing seat, a threaded sleeve 6 threadedly connected to the surface of the first threaded rod 5, and a first clamping plate 7 fixedly connected to the surface of the threaded sleeve 6. The first clamping plate 7 has a Y-axis limiting mechanism, which includes a push plate 8 disposed in the first clamping plate 7, a fixing rod 9 fixedly connected to one side of the push plate 8, and a second clamping plate 10 fixedly connected to the other end of the fixing rod 9.

[0030] Further details: The groove 3 at the top of the lower mold 2 integrates an X / Y axis linkage limiting mechanism. The X-axis limiting mechanism is driven by a bidirectional first threaded rod 5. When the first bolt head 11 is rotated, the reverse thread causes the threaded sleeves 6 on both sides to retract synchronously, driving the convex first clamping plate 7 to move precisely along the limiting groove 12, achieving precise positioning in the X direction. The first clamping plate 7 has a Y-axis limiting component nested inside. When the second threaded rod 14 is screwed in, the drive plate 16 pushes the push plate 8 to compress the spring 13 through the slide frame 17, causing the second clamping plate 10 to generate a continuous clamping force. This design allows the Y-axis clamping force to be linearly adjusted. The length of the first clamping plate 7 and the second clamping plate 10 protruding from the lower mold 2 is less than the thickness of the pad body 4, avoiding interference.

[0031] Example 2

[0032] Please see Figures 1-5 Based on embodiment 1, the surface of the first threaded rod 5 is provided with positive and negative threaded sections with opposite directions of rotation. The other end of the first threaded rod 5 passes through to the outside of the lower mold 2 and is fixedly connected to the first bolt head 11. The first clamping plate 7 is shaped like a convex character. The top of the lower mold 2 is provided with a limiting groove 12 that is adapted to the first clamping plate 7. A spring 13 is sleeved on the surface of the fixing rod 9. One end of the spring 13 is fixedly connected to the inner side of the first clamping plate 7, and the other end of the spring 13 is fixedly connected to one side of the push plate 8. A threaded hole is provided on one side of the lower mold 2, and a second threaded rod 14 is threadedly connected to the inner cavity of the threaded hole. A second bolt head 15 is fixedly connected to one end of the second threaded rod 14. The other end of the second threaded rod 14 is rotatably connected to the drive plate 16 through the bearing seat. Sliding frames 17 are slidably connected to both sides of the drive plate 16. One side of the sliding frame 17 is fixedly connected to one side of the push plate 8.

[0033] Further details: The clamping distance can be easily adjusted manually by rotating the first bolt head 11, and can be adjusted according to different sizes of the pad body 4. The first threaded rod 5 with positive and negative thread sections ensures that the two threaded sleeves 6 move towards each other. The vertical part of the first clamping plate 7 passes through the limiting groove 12 at the top of the groove 3 and is clearance-fitted with it to ensure the stability of the axial movement of the first clamping plate 7. Through the engagement of the threaded hole and the second threaded rod 14, the axial feed of the drive plate 16 is achieved by rotating the threaded rod. The drive plate 16 drives the push plate 8 to move through the slide frame 17. The push plate 8 drives the second clamping plate 10 to move through the fixed rod 9, realizing secondary limiting. During the movement of the two first clamping plates 7, the drive plate 16 and the slide frame 17 drive the push plate 8 on the same side to move, realizing the linkage movement of the two second clamping plates 10 on the same side, improving the limiting effect.

[0034] The working principle of this utility model is as follows: During assembly, the pad body 4 is placed in the center of the groove 3, and the first bolt heads 11 on both sides are rotated clockwise to drive the first threaded rod 5 to rotate. Since the thread directions on both sides of the rod are opposite, the two threaded sleeves 6 move towards each other along the threaded rod, pushing the vertical end face of the first clamping plate 7 to be in close contact with the X-direction side of the pad, and completing the X-direction positioning.

[0035] Rotating the second bolt head 15 with a wrench drives the second threaded rod 14 to advance towards the center of the mold. When the drive plate 16 moves forward, the drive plate 16 drives the push plate 8 to move through the two sliding frames 17. The push plate 8 pushes the second clamping plate 10 to clamp the Y-direction end face of the pad. The pre-compression of the spring 13 ensures that the clamping force is evenly distributed, avoiding local stress concentration. The operation is simple. The mechanical transmission replaces the traditional multi-step adjustment, reducing the installation time of the pad body 4. It also supports the rapid positioning of pad bodies 4 of different sizes, significantly improving the flexible production capacity of the production line.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
