Abstract
Description
Technical Field
[0001] This application relates to the technical field of forging measurement, and more specifically, to a measuring tool for the diameter of forgings. Background Art
[0002] Forging is a processing process. A forging is an object in which metal is subjected to pressure and shaped into the required shape or a suitable compressive force through plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process creates a refined grain structure and improves the physical properties of the metal. Sometimes, the diameter of forged forgings needs to be measured.
[0003] When measuring the diameter of existing forgings, a caliper is required. Due to the different shapes and sizes of forgings and the limited measurement range of the caliper, a larger-sized caliper may be needed for larger-sized forgings, increasing the measurement cost and operation difficulty. For small-sized forgings, which are relatively delicate, the jaws of the caliper may cause unnecessary extrusion or scratching during operation, damaging the surface of the forging and affecting the quality of the forging.

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.
[0032] Referring to Figures 1 - 5 , a measuring tool for the diameter of a forging, comprising a first caliper 1 and a second caliper 2. The second caliper 2 is located on one side of the first caliper 1. Measuring components are provided inside both the first caliper 1 and the second caliper 2, and a storage component is provided on one side of the first caliper 1.
[0033] The measuring component includes a driving unit and a measuring unit. The driving unit includes a knob 3, and the measuring unit includes a fixed clamping plate 4 and a movable clamping plate 5. The knob 3 is used to drive the movable clamping plate 5 to move, and the fixed clamping plate 4 and the movable clamping plate 5 are used to measure the size of the forging.
[0034] Referring to Figures 1 - 4 , cavities 10 are respectively formed inside the first caliper 1 and the second caliper 2. A rotating shaft 8 is rotatably connected to one side of each cavity 10. The top end of each rotating shaft 8 is fixedly connected to the corresponding knob 3, and the bottom end of each rotating shaft 8 is fixedly connected to a second bevel gear 9. A threaded rod 6 is rotatably connected to the inside of each cavity 10. A first bevel gear 7 is fixedly connected to the outer wall of each threaded rod 6. Each first bevel gear 7 meshes with the corresponding second bevel gear 9. A chute is formed on one side of the first caliper 1 and the second caliper 2. Each movable clamping plate 5 passes through the corresponding chute and is threadedly connected to the corresponding threaded rod 6. Support rods 11 are fixedly connected to the bottoms of both the fixed clamping plate 4 and the movable clamping plate 5. A roller 12 is rotatably connected to one side of each support rod 11.
[0035] The overall applicable range can be increased by the first caliper 1 and the second caliper 2. The specific operation method is as follows: Since the size of the first caliper 1 is larger than that of the second caliper 2, for forgings with different sizes, the first caliper 1 and the second caliper 2 can be used in combination. When in use, first rotate the knob 3. By rotating the knob 3, the rotating shaft 8 fixedly connected thereto is driven to rotate. The knob 3 at the top of the rotating shaft 8 facilitates the operator to apply force, and the second bevel gear 9 at the bottom of the rotating shaft 8 rotates accordingly. Since the second bevel gear 9 meshes with the first bevel gear 7, the first bevel gear 7 is driven to rotate, and then the threaded rod 6 fixedly connected to the first bevel gear 7 rotates. After the threaded rod 6 rotates, the moving clamping plate 5 threadedly connected thereto starts to move under the restriction of the chute, adjusting the distance between the moving clamping plate 5 and the fixed clamping plate 4 to be slightly larger than the diameter of the forging. Then, place the forging between the fixed clamping plate 4 and the moving clamping plate 5, and rotate the knob 3 in the reverse direction again to make the moving clamping plate 5 approach the fixed clamping plate 4 until the moving clamping plate 5 and the fixed clamping plate 4 tightly clamp the forging. At this time, the diameter size of the forging can be determined by reading the scale on the caliper. During the measurement process, the support rods 11 and rollers 12 at the bottoms of the fixed clamping plate 4 and the moving clamping plate 5 can prevent the jaws from scratching the forging.
[0036] Through the first caliper 1 and the second caliper 2, the first caliper 1, the second caliper 2 or the combination of both can be flexibly selected according to the actual size of the forging. Whether it is a large forging or a small forging, a suitable measuring tool can be found, greatly increasing the overall applicable range, meeting the measurement requirements in different production scenarios, and the precise movement control of the moving clamping plate 5 can be achieved through the measuring assembly. The operator can rotate the knob 3 to precisely adjust the distance between the moving clamping plate 5 and the fixed clamping plate 4 to ensure that it can adapt to forgings of different sizes, improving the measurement accuracy, without a complex operation process, and improving the efficiency of the measurement work.
[0037] Refer to Figure 4 , limiting grooves 18 are provided on one side of both the first caliper 1 and the second caliper 2. A fixed wheel 17 is provided on one side of each knob 3. The structure of the fixed wheel 17 is adapted to the structure of the knob 3. A slider 19 is fixedly connected to the bottom of each fixed wheel 17, and each slider 19 is respectively slidably connected to the corresponding limiting groove 18. Friction blocks are provided on the inner wall of the limiting groove 18.
[0038] When adjusting the position of the moving clamping plate 5 and the fixed clamping plate 4 to measure the forging, the fixed wheel 17 can be slid along the limiting groove 18 to a position where it fits the knob 3. Since the structure of the fixed wheel 17 is adapted to the structure of the knob 3, it can fit tightly on the knob 3, playing a role in fixing the knob 3 and preventing the knob 3 from accidentally rotating during the measurement process, resulting in a change in the position of the moving clamping plate 5, thereby ensuring the stability and accuracy of the measurement result.
[0039] The fixed wheel 17 plays an effective role in fixing the knob 3, which can prevent the knob 3 from rotating due to accidental touch or other external force factors when measuring the diameter of the forging, thus avoiding the change of the position of the moving splint 5 and ensuring the stability and accuracy of the measurement result.
[0040] Referring to Figure 1 , the storage assembly includes a storage box 15 which is fixedly installed on one side of the first caliper 1. One side of the storage box 15 is rotatably connected with a rotating rod 16. One end of the second caliper 2 is fixedly connected with the rotating rod 16. The structure of the storage box 15 is adapted to the structure of the second caliper 2. Pointer 13 is provided on one side of each of the two moving splints 5, and scale 14 is provided on the outer walls of the first caliper 1 and the second caliper 2. The pointer 13 and the scale 14 are correspondingly arranged.
[0041] The provision of the storage box 15 provides a dedicated storage space for the second caliper 2. When the second caliper 2 is not needed for measurement, the second caliper 2 can be rotated and stored in the storage box 15 through the rotating rod 16. This can effectively prevent the second caliper 2 from being damaged or lost due to random placement, playing a good role in protection and organization. At the same time, the structure of the storage box 15 is adapted to the second caliper 2, which can ensure the stable storage of the second caliper 2 in the storage state, does not occupy too much space, is convenient for carrying and storing the entire measuring tool, and improves the portability and practicality of the measuring tool.
[0042] Working principle: For forgings of different sizes, the first caliper 1 and the second caliper 2 can be used in combination. When in use, first rotate the knob 3. By rotating the knob 3, the rotating shaft 8 fixedly connected thereto is driven to rotate. The knob 3 at the top of the rotating shaft 8 facilitates the operator to apply force, and the second bevel gear 9 at the bottom of the rotating shaft 8 rotates accordingly. Since the second bevel gear 9 meshes with the first bevel gear 7, the first bevel gear 7 is driven to rotate, and then the threaded rod 6 fixedly connected with the first bevel gear 7 rotates. After the threaded rod 6 rotates, the moving splint 5 threadedly connected therewith starts to move under the restriction of the chute, adjusting the distance between the moving splint 5 and the fixed splint 4 to be slightly larger than the diameter of the forging. Then, place the forging between the fixed splint 4 and the moving splint 5, and rotate the knob 3 in the reverse direction again to make the moving splint 5 approach the fixed splint 4 until the moving splint 5 and the fixed splint 4 tightly clamp the forging. At this time, the diameter size of the forging can be determined by reading the scale on the caliper. During the measurement process, the support rods 11 and the rollers 12 at the bottoms of the fixed splint 4 and the moving splint 5 can prevent the claws from scratching the forging.
[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
