Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tool for three-dimensional angle measurement and length dimension conversion. Background Art

[0002] During mechanical assembly, Figure 1 The schematic diagram of the product to be measured requires that after the part 1 51 of the workpiece 5 is docked with the part 2 52, the nozzle of the part 1 51 and the flange of the part 2 52 are consistent in a certain hole direction. Since the part 1 51 and the part 2 52 are threaded, the uncertainty of the processing of the thread inlet end leads to the inconsistency of the thread inlet of each part. After the parts are docked, the nozzle direction and the flange hole direction are uncertain. It is usually necessary to repair the end face of the part 2 52 to ensure the consistency of the nozzle and flange direction. The amount of end face filing can only be adapted little by little through experience, resulting in a long filing process cycle.

[0003] In order to solve the problem of long filing cycle and determine the end face filing amount, a device for three-dimensional angle measurement and length dimension conversion was designed by using three-dimensional projection and pitch conversion. Utility Model Content

[0004] The utility model aims to provide a device for converting length dimensions into three-dimensional angle measurements, thereby shortening the processing cycle and improving the efficiency.

[0005] The technical solution of the utility model is as follows: a device for three-dimensional angle measurement conversion length dimension, comprising a base, a conversion dial, a pin and a pointer. The base is a hollow cylindrical structure as a whole, wherein one end face is provided with a groove along the circumferential direction, and the groove cooperates with the pin; the conversion dial is a circular ring structure provided with angle scale lines along the circumferential direction, and a hole is provided to avoid the angle scale lines, and the hole cooperates with the pin. The pin passes through the hole of the conversion dial and is fixed in the groove of the base, and the center axis of the workpiece passes through the hollow position of the conversion dial and the base, and is fixed above the conversion dial by the pin, and the nozzle direction of the workpiece is determined to be aligned with the angle scale area of ​​the conversion dial, and a positioning hole is provided at one end of the pointer and the other end is the pointer pointing end, and the positioning hole of the pointer is sleeved on the nozzle of the workpiece to ensure that the pointer pointing end is perpendicular to the conversion dial, thereby recording the angle difference between the nozzle and the flange. The projection method is used to measure the spatial three-dimensional angle between the nozzle and the flange through the pointer. Therefore, according to the pitch and angle difference of the thread of the part, the height required for filing is calculated. It is suitable for workpieces with different nozzle and flange angles. For a thread with a pitch of P, one thread is calculated for every 360° rotation, that is, the height dimension is P. When the angle difference between the nozzle and the flange is θ, the dimension that needs to be filed is h = θ*P / 360°.

[0006] Furthermore, the number of the grooves is 1 to 3.

[0007] Furthermore, 1 to 3 holes are provided.

[0008] When in use, the product is limited on the measuring device by a pin, the nozzle is inserted into the pointer, and the three-dimensional angle of the space is measured by projection. Then, according to the conversion of pitch and angle, the end face filing size is calculated. The measuring device is made into a modular type, which reduces the maintenance cost, and the conversion dial can be adjusted to adapt to products with different nozzle and flange angles.

[0009] Beneficial effects of the utility model:

[0010] (1) The tool can quickly and accurately calculate the amount of filing, shortening the processing cycle.

[0011] (2) The tools are modular, making processing, assembly and maintenance very convenient.

[0012] (3) Easy to operate and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the present invention will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0025] See also Figure 2-5 , the figure shows a schematic diagram of the structure of the device for three-dimensional angle measurement and conversion of length size provided by the utility model, including a base 1, a conversion dial 2, a pin 3 and a pointer 4, the base 1 is a hollow cylindrical structure as a whole, and a groove 11 is provided on one side end face of the base 1 along the circumferential direction, and the groove 11 cooperates with the pin 3; the conversion dial 2 is a circular ring structure with angle scale lines along the circumferential direction, and a hole 21 is provided to avoid the angle scale lines, and the hole 21 cooperates with the pin 3, and the pin 3 passes through the hole 21 of the conversion dial 2 and is fixed in the groove 11 of the base 1, and the center axis of the workpiece 5 passes through the hollow position of the conversion dial 2 and the base 1, and is fixed above the conversion dial 2 by the pin 3, and the nozzle direction of the workpiece 5 is determined to be aligned with the angle scale area of ​​the conversion dial 2, and the pointer 4 is provided with a positioning hole 41 at one end and a pointer pointing end 42 at the other end, and the positioning hole 41 of the pointer 4 is sleeved on the nozzle of the workpiece 5 to ensure that the pointer 4 pointing end 42 is perpendicular to the conversion dial 2, thereby recording the angle difference between the nozzle and the flange. The projection method enables the three-dimensional angle between the nozzle and the flange to be measured through the pointer. Therefore, the height that needs to be filed can be calculated based on the pitch and angle difference of the workpiece thread. For a thread with a pitch of P, the thread moves one thread per 360° rotation, that is, the height dimension is P. When the angle difference between the nozzle and the flange is θ, the dimension that needs to be filed is h = θ*P / 360°.

[0026] For example, if the pitch of the thread is P = 1.5mm, calculate that the thread moves one thread turn for every 360° rotation, pass the pin 3 through the conversion dial 2 and fix it on the chassis 1, pass the center axis of the workpiece 5 through the conversion dial 2 and the base 1, and fix it above the conversion dial 2 with the pin 3, and make sure that the nozzle direction of the workpiece 5 is aligned with the angle scale area of ​​the conversion dial 2, then make sure that the pointer 4 points to the end 42 perpendicular to the conversion dial 2, and record the angle difference between the nozzle and the flange as 10°. The size that needs to be filed is h = 10°*1.5mm / 360° = 0.042mm.

[0027] By analogy, the workpiece is fixed on the base and the conversion dial by pins, and the angle difference between the two corresponding threaded parts can be measured by the pointer, and the required adjustment size can be obtained according to the pitch of the thread. Products that adapt to different nozzle and flange angles.

[0028] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Any modification or equivalent substitution made to the technical solution of the utility model by ordinary technicians in this field shall be included in the scope of the claims of the utility model as long as it does not depart from the spirit and scope of the technical solution of the utility model.
