Description

Technical Field

[0001] The utility model relates to the technical field of plug gauge equipment, and particularly relates to a taper plug gauge for alloy molds. Background Art

[0002] In the fields of mold manufacturing and precision machining, as an important inspection tool, plug gauges are widely used in the measurement of hole diameters, hole pitches, minor diameters of internal threads, and mold dimensions. With the continuous progress of industrial technology, the requirements for mold accuracy and inspection efficiency are increasing day by day, and the limitations of traditional plug gauges in design and use are gradually emerging. Especially in the process of mold manufacturing, due to the complexity and diversity of mold structures, higher requirements are put forward for the flexibility and durability of plug gauges.

[0003] At present, most of the common plug gauges on the market are made of a single material, such as white steel, tungsten steel, etc. Although these materials have high hardness and wear resistance, there are still many deficiencies when facing the complex and changeable mold inspection requirements. For example, the cone and the handle of the traditional plug gauge often adopt an integrated design. Once the cone part is worn or damaged, the entire plug gauge needs to be replaced, which not only increases the use cost but also affects the inspection efficiency. In addition, the disassembly and assembly process of some plug gauges is complicated, and it is not convenient to quickly replace the cone, making it difficult to meet the needs of high-efficiency production. Content of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a taper plug gauge for alloy molds that is convenient for connecting and replacing the cone.

[0005] The embodiment of the utility model specifically adopts the following technical solutions to achieve the above purpose: A standard plug gauge for alloy molds includes a handle and a cone. A connecting body is arranged between the handle and the cone. The connecting body includes a base plate. A screw rod connected to the cone is arranged on the base plate, and a threaded post connected to the handle is arranged on the side wall of the base plate.

[0006] As a further improvement of the above technical solution:

[0007] The number of the screw rods is multiple and they are evenly distributed along the circumferential direction of the base plate.

[0008] Through holes corresponding to the positions of the screw rods are arranged in the cone. A storage cavity coaxial with the through holes is arranged on the bottom surface of the cone. An internal hexagonal nut located in the storage cavity is arranged at the end of the screw rod.

[0009] A threaded sleeve connected to the threaded post is arranged at the end of the handle. A driving module is arranged in the middle of the handle. A driving rod connected to the threaded sleeve is arranged at the output end of the driving module.

[0010] The upper part of the threaded sleeve is provided with a transmission rod connected to the driving rod, and a positioning bearing sleeved outside the transmission rod is arranged inside the handle.

[0011] A limiting plate is arranged at the upper part of the transmission rod, and a compression spring sleeved outside the transmission rod is arranged between the limiting plate and the positioning bearing.

[0012] A plugging hole corresponding to the position of the driving rod is arranged at the top of the transmission rod, a positioning groove coaxially distributed with the plugging hole is arranged on the upper surface of the transmission rod, and a clamping convex rib matched with the positioning groove is arranged on the side wall of the driving rod.

[0013] The beneficial effects of the embodiment of the utility model are as follows: 1. The alloy die standard plug gauge includes a handle and a cone, and a connecting body is arranged between the handle and the cone. The connecting body includes a substrate, a screw rod connected to the cone is arranged on the substrate, and a threaded column connected to the handle is arranged on the side wall of the substrate. The design of the connecting body can realize the detachable connection between the handle and the cone, which is convenient for replacing the cone and subsequent maintenance.

[0014] 2. A threaded sleeve connected to the threaded column is arranged at the end of the handle, a driving module is arranged in the middle of the handle, and a driving rod connected to the threaded sleeve is installed at the output end of the driving module. The driving module adopts a driving motor, and the driving motor is used to drive the threaded sleeve to rotate, and then drive the cone to rotate, so as to replace the conventional manual rotation. Moreover, the handle does not need to rotate during rotation. Compared with the existing method of driving the cone to rotate by rotating the handle, the phenomenon that the cone is deflected due to the deflection of the handle during rotation can be effectively reduced, and the positioning effect of the cone is enhanced.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0022] As Figures 1-5 shown, the alloy die standard plug gauge of this embodiment includes a handle 1 and a cone 2. A connecting body is provided between the handle 1 and the cone 2. The connecting body includes a substrate 3. A screw 4 connected to the cone 2 is provided on the substrate 3. A threaded post 5 connected to the handle 1 is provided on the side wall of the substrate 3. The design of the connecting body can realize the detachable connection between the handle 1 and the cone 2, which is convenient for replacing the cone 2 and subsequent maintenance.

[0023] The number of screws 4 is multiple and they are evenly distributed along the circumferential direction of the substrate 3.

[0024] A through hole 6 corresponding to the position of the screw 4 is provided in the cone 2. A storage cavity 7 coaxial with the through hole 6 is provided on the bottom surface of the cone 2. An Allen nut 8 located in the storage cavity 7 is provided at the end of the screw 4. Connecting the cone 2 and the substrate 3 through multiple screws 4 can prevent the cone 2 from rotating during operation.

[0025] A threaded sleeve 9 connected to the threaded post 5 is provided at the end of the handle 1. A drive module is provided in the middle of the handle 1. The output end of the drive module is equipped with a drive rod 10 connected to the threaded sleeve 9. The drive module uses a drive motor. The drive motor is used to drive the threaded sleeve 9 to rotate, and then drive the cone 2 to rotate, so as to replace the conventional manual rotation. Moreover, the handle 1 does not need to rotate during rotation. Compared with the existing method of driving the cone 2 to rotate by rotating the handle 1, it can effectively reduce the phenomenon that the cone 2 is deflected due to the deflection of the handle 1 during rotation, and enhance the positioning effect of the cone 2.

[0026] The upper part of the threaded sleeve 9 is provided with a transmission rod 11 connected to the driving rod 10. A positioning bearing 12 sleeved outside the transmission rod 11 is arranged inside the handle 1. A limiting plate 13 is arranged at the upper part of the transmission rod 11. A compression spring 14 sleeved outside the transmission rod 11 is arranged between the limiting plate 13 and the positioning bearing 12. In the normal state, the compression spring 14 is in a compressed state under the influence of the gravity of the cone 2. At this time, the transmission rod 11 is not connected to the driving rod 10. When the cone 2 performs a detection operation and is placed in the hole to be measured, at this time, the compression spring is reset without being affected by gravity. After the transmission rod 11 moves upward and engages with the transmission rod 10, the driving motor drives the threaded sleeve 9 to rotate.

[0027] The top of the transmission rod 11 is provided with a plug hole 15 corresponding to the position of the driving rod 10. A counterpoint groove 16 coaxially distributed with the plug hole 15 is arranged on the upper surface of the transmission rod 11. A clamping convex rib 17 cooperating with the counterpoint groove 16 is arranged on the side wall of the driving rod 10. A buffer plate is arranged at the bottom of the plug hole 15, and a buffer spring is arranged below the buffer plate to provide an avoidance position for the insertion of the transmission rod 11.
