[0002] The bevel lining is a common machined product. The upper part is generally a sharp-angle structure consisting of two bevels. Under different product requirements, some products have high requirements for the angle and surface finish of each bevel, and need to be surface ground by a grinder. In the specific processing process, the two bevels of the upper plane need to be ground separately on an ordinary grinder in different processes. Generally, the grinding of the other bevel needs to be completed after the grinding of the first bevel is completed. Under the existing detection equipment, the angle accuracy can be guaranteed by angle ruler detection.

[0003] However, due to separate grinding, it is impossible to effectively control the grinding amount of each bevel by detecting the total height through existing equipment. That is, when processing the first bevel, it is necessary to control the grinding allowance of the second bevel. Otherwise, the upper sharp angle offset may be inconsistent with the design drawing due to poor control of the grinding depth of the first bevel, which will ultimately cause product size deviation.

DETAILED DESCRIPTION

[0025] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figure 1 、 Figure 2 、 Figure 3 As shown, Figure 1 A measurement diagram of the inclined lining plate measuring tool; Figure 2 A three-dimensional structural view of the inclined lining plate measuring tool; Figure 3 2 is a structural view of the clamping plate.

[0028] The bevel lining plate measuring tool of the present invention is used to detect the bevel machining allowance of the bevel lining plate. The bevel lining plate 1 includes a bevel surface 11 to be machined, a bottom plane 12 and a vertical surface 13. The bevel surface 11 to be machined is connected to the bottom plane 12 through the vertical surface 13. The bottom plane 12 is horizontally arranged, and the vertical surface 13 is perpendicular to the bottom plane 12. The bevel surface 11 to be machined is machined so that the bevel surface 11 to be machined forms a workpiece bevel surface 14 that meets the design requirements. Correspondingly, the height dimension of the vertical surface 13 is also reduced to the design height that meets the design requirements after machining.

[0029] The bevel lining measuring tool includes a clamping plate 2, a measuring groove is provided in the clamping plate 2, and the measuring groove includes a first measuring surface 21, a second measuring surface 22 and a third measuring surface 23. The first measuring surface 21 is connected to the third measuring surface 23 through the second measuring surface 22. The first measuring surface 21 is arranged perpendicular to the second measuring surface 22. The angle dimension between the first measuring surface 21 and the third measuring surface 23 is consistent with the angle dimension between the inclined surface 14 of the workpiece and the bottom plane 12.

[0030] Preferably, the extension length dimension of the second measuring surface 22 from the first measuring surface 21 to the third measuring surface 23 is consistent with the design height dimension of the vertical surface 13, so that after the processing of the inclined surface 11 to be processed is completed, when the second measuring surface 22 is aligned with the vertical surface 13, the third measuring surface 23 and the workpiece inclined surface 14 are in contact.

[0031] Preferably, the bevel lining measuring tool also includes a depth gauge 3, which is used to measure the distance between the vertical surface 13 and the second measuring surface 22. By detecting the distance between the vertical surface 13 and the second measuring surface 22, the machining allowance from the bevel surface 11 to be machined to the workpiece bevel surface 14 can be calculated, thereby facilitating the machining control operation of the bevel surface 11 to be machined.

[0032] Preferably, a placement hole 24 is provided on the second measuring surface 22, the depth gauge 3 is arranged in the placement hole 24, and the extension direction of the depth gauge 3 is arranged perpendicular to the second measuring surface 22. One end of the depth gauge 3 is placed in contact with the vertical surface 13, and then the position of the second measuring surface 22 on the depth gauge 3 can be used to intuitively detect the distance between the vertical surface 13 and the second measuring surface 22.

[0033] Generally, the cross-sectional shape and size of the placement hole 24 are consistent with the cross-sectional shape and size of the depth gauge 3 , thereby ensuring that the relative movement state of the depth gauge 3 and the second measuring surface 22 is stable.

[0034] Preferably, the end of the depth gauge 3 disposed in the measuring groove is the starting end of the depth gauge 3 , and the scale value of the starting end of the depth gauge 3 is 0 mm.

[0035] Specifically, the depth gauge 3 is provided with a cursor 4 that can slide freely along the depth gauge 3. The cursor 4 is fixed to the clamping plate 2 and is provided with a locking screw to secure the cursor 4 to the depth gauge 3. After the measurement is completed, the cursor 4 can be locked to the depth gauge 3, making it easier to read the corresponding position of the second measuring surface 22 on the depth gauge 3.

[0036] The present invention can effectively control the angular accuracy of the inclined surface of the inclined lining plate 1 and is used to control the machining allowance of the inclined surface of the inclined lining plate 1, thereby avoiding the calculation of the machining allowance of the inclined surface based on the total height in the prior art, and avoiding the problem of sharp angle offset caused by poor control of the grinding depth of the first inclined surface. At the same time, it can reduce the lengthening of the construction period caused by practical three-dimensional detection or other auxiliary means of detection, effectively save time costs, and improve work efficiency.

[0037] Example 2

[0038] In this embodiment, the extension length of the second measuring surface 22 from the first measuring surface 21 to the third measuring surface 23 may be smaller than the designed height dimension of the vertical surface 13. In this case, when the third measuring surface 23 and the workpiece inclined surface 14 are in contact, a reserved gap exists between the second measuring surface 22 and the vertical surface 13. When calculating the machining allowance, the reserved gap needs to be subtracted from the distance dimension between the vertical surface 13 and the second measuring surface 22 to obtain the correct machining allowance.

[0039] Correspondingly, the cursor 4 is not fixed to the clamping plate 2, and the cursor 4 is arranged in the measuring groove. In this embodiment, before detection, the cursor 4 is fixed and the distance between the cursor 4 and the starting end of the depth gauge 3 is set to the reserved gap, so that the machining allowance can be calculated by reading the size of the depth gauge 3 between the cursor 4 and the second measuring surface 22, that is, by using the cursor 4 as the initial zero point.

[0040] Example 3

[0041] like Figure 4 As shown, Figure 4Schematic diagram of the principle of the measurement method; the measurement method of the present invention adopts the inclined lining measuring tool, and the specific process is: after the first measuring surface 21 is fitted with the bottom plane 12, the inclined surface 11 to be processed and the third measuring surface 23 are fitted, the starting end of the depth gauge 3 is brought into contact with the vertical surface 13, so as to detect the distance between the vertical surface 13 and the second measuring surface 22, and the machining allowance of the inclined surface 11 to be processed is obtained by calculation.

[0042] Specifically, the calculation formula for the machining allowance of the inclined surface 11 to be machined is:

[0043] X1=X2×tanα×cosα=X2×sinα

[0044] Among them, X1 is the machining allowance size of the inclined surface 11 to be machined; X2 is the distance size between the second measuring surface 22 and the vertical surface 13; α is the angle between the workpiece inclined surface 14 and the bottom plane 12; when the inclined liner measuring tool and the inclined liner 1 are at X1=0, the measuring groove and the inclined liner 1 are fully fitted.

[0045] The present invention uses the simple structure of the inclined lining measuring tool and obtains the machining allowance size of the inclined surface 11 to be machined by calculation, which can reduce the lengthening of the construction period caused by practical three-dimensional detection or other auxiliary means of detection, effectively save time costs, and improve work efficiency.

[0046] The above description is merely a preferred embodiment of the present invention and is intended to be illustrative rather than restrictive of the present invention. Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the present invention within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
