The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

A measuring tool for reference marking of a casting of a speed reducer is structurally illustrated in FIGS. 1-5, and in the embodiment, as shown in the drawings, the measuring tool comprises: the bearing platform 1, a first measuring component and a second measuring component. The bearing platform 1 is used for bearing the casting, the first measuring component is used for detecting the height of the casting, and the second measuring component is used for detecting the length and the width of the casting.

As shown in fig. 3, a casting placing area 11 is provided on the carrying platform 1, and during operation, a worker can place a casting to be measured on the casting placing area 11 by means of a crane. Be equipped with the guide rail on casting placement area 11's week side, can restrict the motion route of first measuring component through the guide rail to make things convenient for the staff to measure along each angle of casting.

As shown in fig. 4, the first measurement assembly includes: a base 2, a first guide bar 3 and a first connecting block 4. The bottom of base 2 is equipped with guide post 21, guide post 21 slides and sets up inside the guide rail. First guide bar 3 sets up at 2 tops of base, and first guide bar 3 is mutually perpendicular with load-bearing platform 1, is equipped with first scale 31 on the lateral wall of first guide bar 3. The first connecting block 4 is slidably arranged on the first guide rod 3, a first observation window 41 is arranged on the side wall of the first connecting block 4, and the first observation window 41 is aligned with the first graduated scale 31.

In operation, the operator can slide the base 2 into proximity with the measurement location of the casting and then adjust the height of the first connecting block 4. When the height of the first connecting block 4 is level with the height of the casting, the worker reads the readings on the first scale 31 through the first observation window 41 to measure the height of the casting.

As shown in fig. 5, the second measurement assembly includes: a second guide bar 6, a second connecting block 7 and a probe 8. The second guide rod 6 is arranged on the side wall of the first connecting block 4, the second guide rod 6 is parallel to the bearing platform 1, and when the first connecting block 4 slides along the first guide rod 3, the second guide rod 6 can move synchronously. In addition, be equipped with second scale 61 on the lateral wall of second guide bar 6, second connecting block 7 slides and sets up on second guide bar 6, and is equipped with second observation window 71 on the lateral wall of second connecting block 7, second observation window 71 is aligned with second scale 61. A probe 8 is arranged below the second connecting block 7, and the top end of the probe 8 is hinged with the bottom surface of the second connecting block 7.

When the base 2 slides to the position near the measuring position of the casting and the height adjustment of the first connecting block 4 is completed, the worker can drive the second sliding block 7 to slide along the second guide rod 6. Before sliding, the probe 8 should be driven to rotate by taking the hinge point as an axis, so that the probe 8 is parallel to the second guide rod 6, and interference of the probe 8 in the sliding process of the second connecting block 7 is avoided. When the second connecting block 7 is slid near the edge of the casting, the probe 8 should be rotated again so that the probe 8 is perpendicular to the load-bearing platform 1. With the movement of the second connecting block 7, the probe 8 will come into contact with the casting, at which time the operator can read the reading of the second graduated scale 61 through the second observation window 71. And then, the worker can measure the other side of the casting according to the process, and after the measurement is finished, the difference value between the two readings is the size parameter of the casting.

Optionally, in order to facilitate the measurement of the length and the width of the casting by the staff using the device, the guide rail comprises a first sliding section 121, a connecting section 122 and a second sliding section 123 which are sequentially communicated, and the first sliding section 121 is perpendicular to the second sliding section 123. Since the first and second sliding

sections

121 and 123 are perpendicular to each other, the width dimension parameter of the casting can be measured by the second measuring assembly when the base 2 is located inside the first sliding section 121, and the length dimension parameter of the casting can be measured by the second measuring assembly when the base 2 is located inside the second sliding section 123.

In addition, in order to avoid the base 2 from being separated from the guide track in the sliding process, the bottom of the guide column 21 is provided with a limiting block 211, and the cross-sectional area of the limiting block 211 is larger than that of the guide column 21. Correspondingly, a limiting groove for accommodating the limiting block 211 is arranged below each of the first sliding section 121 and the second sliding section 123.

As shown in fig. 4, in order to prevent the first measuring assembly from rotating during sliding along the guide track, the limiting block 211 should be square. Since the orientation of the second measuring assembly inside the first sliding section 121 and the second sliding section 123 is different, the cross-sectional area of the connecting section 122 should be larger than that of the limiting block 211 for the convenience of adjustment. When the base 2 moves inside the connecting section 122, the operator can pull out the stopper 211 and adjust the orientation of the second measuring component.

Optionally, in order to improve the measurement efficiency of the apparatus, a third scale 13 and a fourth scale 14 may be disposed on the bearing platform 1. The third scale 13 is parallel to the first sliding section 121, and the fourth scale 14 is parallel to the second sliding section 123. The sliding distance of the base 2 can be measured by the third graduated scale 13 and the fourth graduated scale, so that the device can simultaneously obtain the length and the width of a casting in one measuring process.

Illustratively, the base 2 should be inside the first sliding section 121 when making a width measurement of the casting. The operator can drive the base 2 to slide from one end of the casting to the other and record the sliding distance of the base 2 through the third scale 13. At this time, the scale of the first scale 31 is the height of the casting, the scale of the second scale 61 is the width of the casting, and the sliding distance of the base 2 recorded by the third scale 13 is the length of the casting.

In order to improve the measurement accuracy of the device, the first measurement assembly described in this embodiment further includes a locking screw 5 and a fixing bolt 9. The position of the first connecting block 4 can be fixed by the locking screw 5, and the position of the base 2 can be fixed by the fixing bolt 9.

When the height of first connecting block 4 and the height looks parallel and level of foundry goods, staff's accessible first fixation nut 51 goes on going up spacingly to first connecting block 4 to carry out down spacingly through second fixation nut 52 to first connecting block 4, thereby avoid first connecting block 4 to take place the abnormal sliding.

The fixing bolt 9 is arranged on the base 2, specifically, a threaded hole 22 is arranged on the top surface of the base 2, the threaded hole 22 is perpendicular to the bearing platform 1, and the fixing bolt 9 is arranged inside the threaded hole 22. After the base 2 moves to the preset measuring position, the worker can rotate the fixing bolt 9 downwards, so that the bottom of the fixing bolt 9 abuts against the top surface of the bearing platform 1. The friction force between the base 2 and the bearing platform 1 can be improved through the abutting action, so that the base 2 is prevented from sliding abnormally.

Optionally, for improving the fixing effect of the fixing bolt 9, the bottom of the fixing bolt 9 is provided with an extrusion gasket 91, and the extrusion gasket 91 is rotatably connected with the fixing bolt 9. Correspondingly, the top surface of the bearing platform 1 is provided with an accommodating groove 15, the accommodating groove 15 is parallel to the guide rail, and the accommodating groove 15 is aligned with the fixing bolt 9. The anti-slip strip 151 is arranged inside the accommodating groove 15, and anti-slip stripes are arranged on the top surface of the anti-slip strip 151.

When the staff rotated set screw 9 downwards, extrusion gasket 91 will support with antislip strip 151 counterbalance, can further promote the frictional force between base 2 and the load-bearing platform 1 through the cooperation of extrusion gasket 91 and antislip strip 151 to promote fixing bolt 9's fixed effect.
