Description

Technical Field

[0001] The utility model belongs to the technical field of equipment and mainly relates to a three-dimensional marking instrument auxiliary device. Background Art

[0002] The 3D measuring and marking instrument is a highly efficient and multifunctional spatial three-coordinate measuring and marking device. Through three mutually perpendicular moving X-axis, Y-axis and Z-axis bodies, the measuring head or the marking needle head can simultaneously move in three coordinate directions for measurement and marking. It is widely used in many industries such as transportation equipment manufacturing, machinery manufacturing, electronic equipment manufacturing, steel, casting, etc., and can replace square boxes, marking needles, and height gauges for marking and testing equipment. It can quickly and efficiently complete the three-dimensional marking and detection of the spatial dimensions and curved surfaces of complex parts, components, and mold parts. Due to the large outline dimensions of large steel castings, the measurement range of the equipped three-dimensional marking instrument is 10m long, 3m wide and 4m high, and the extension dimension of its horizontal arm is about 3m. In the process of measuring castings, the inspection personnel need to frequently push and pull the marking instrument in the three directions of X\Y\Z. In particular, when measuring dimensions that are far away from the three-dimensional marking instrument, it is necessary to first push and pull the marking instrument at the vertical pull rod position next to the marking instrument column to displace it in the X direction to the position of the measured dimension, and then adjust and extend the horizontal arm up and down (displacement in the Z and Y directions) to make the probe close to the position of the measured point, and then the measurement personnel move to the probe position to measure the dimension. Generally, there are hundreds of measurement points on castings, and the measurement personnel need to go back and forth between the column and the probe position hundreds of times, which seriously affects the efficiency of casting dimension detection and increases the operation intensity of the measurement personnel. Utility Model Content

[0003] Based on the above problems, the utility model proposes a three-dimensional marking instrument auxiliary device to solve the problem that the large-scale reciprocating movement between the column and the probe during the measurement process seriously affects the efficiency of casting size detection and increases the operating intensity of the measurement personnel.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0022] like Figure 1-2 As shown, the embodiment of the utility model discloses a three-dimensional marking instrument auxiliary device, which is applied to the measurement process of the three-dimensional marking instrument. During the measurement process, the operator can push and pull the push-pull rod with one hand to move the machine body, and move the support rod with one hand to make the probe quickly contact the measured size. The disclosed three-dimensional marking instrument auxiliary device includes a push-pull device, a support rod, a fixing frame, a probe, a column and a base.

[0023] Specifically, the push-pull device includes a push-pull rod 1 and a bearing 2. The bearing 2 is arranged on a fixed frame 5. There is an axial hole on the bearing 2. The push-pull rod 1 passes through the axial hole of the bearing 2. The bearing 2 and the fixed frame 5 are fastened together by bolts and nuts; the mounting sleeve 4 is arranged on the fixed frame 5, the support rod 3 passes through the mounting sleeve 4, and the mounting sleeve 4 and the fixed frame 5 are fastened together by bolts and nuts; the column 7 is rotatably connected to the base 8, and a sliding track 9 is arranged under the base 8.

[0024] In one embodiment, if Figure 1-2 As shown, a lock is also provided on the bearing 2, and the probe 6 is provided on the support rod 3. The push-pull rod 1 can slide to a specific position along the Y-axis direction in the axial hole of the bearing 2 under the action of force, and is fixed by the lock on the bearing. When a marking instrument is needed, the push-pull rod 1 is extended. After the lock is fixed, the support rod 3 is extended or shortened, and the push-pull rod 1 is directly pushed to enable the probe 6 to mark or measure.

[0025] Furthermore, the push-pull rod 1 and the support rod 3 are in the same direction, and the push-pull rod 1 is directly pushed and pulled during the measurement and marking process, thereby ensuring that the support rod 3 is not subjected to force in the horizontal direction, eliminating the problem of low marking accuracy and inaccurate measurement due to bending of the horizontal arm.

[0026] Furthermore, the push-pull rod 1 is in the shape of a round rod and has a smooth surface, which ensures that the friction force is very small when pushing and pulling.

[0027] Furthermore, the push-pull rod 1 passes through the axial hole of the bearing 2, and there is a dimensional gap to ensure that the push-pull rod 1 moves forward and backward without resistance. Optionally, the dimensional gap is 0.2mm-0.8mm.

[0028] Furthermore, the support rod 3 passes through the mounting sleeve 4, and there is a size gap to ensure that the support rod 3 moves forward and backward without resistance. Optionally, the size gap is 0.2mm-0.8mm.

[0029] In one embodiment, if Figure 1-2 As shown, the fixing frame 5 is nested on the column 7 and is provided with a limiting device. By pushing and pulling the push-pull rod 1 in the Z-axis direction, the fixing frame 5 can slide in the Z-axis direction to the specific height required by the probe 6. The fixing frame 5 is fixed on the column 7 by the limiting device. When it is necessary to mark or measure, the push-pull rod 1 is pushed and pulled in the Y-axis direction to extend or shorten the push-pull rod 1. After the lock is fixed, the support rod 3 is extended or shortened to directly push the push-pull rod 1, and the probe 6 is used for marking or measurement.

[0030] Furthermore, the contact surface between the fixing frame 5 and the column 7 is convex, and the column 7 is concave. The fixing frame 5 and the column 7 cooperate with each other, and the fixing frame 5 can slide on the column 7 through the push-pull rod 1. Optionally, the column 7 can be dovetail groove-shaped, corrugated-shaped, or groove-shaped.

[0031] In one embodiment, if Figure 1-2 As shown, the column 7 and the base 8 are rotatably connected, and a fixing buckle is provided. The base 8 is nested on the slide rail 9 on the horizontal plane. By pushing the push-pull rod 1, the connection between the column 7 and the base 8 is pushed to rotate, and the probe 6 is rotated to the desired preset position. The fixing buckle between the base 8 and the column 7 is fastened to fix it. Then, by pushing the push-pull rod 1, the base 8 can be moved to the desired position along the X-axis direction of the slide rail 9 under the action of the thrust. When marking or measurement is required, the push-pull rod 1 is pushed and pulled in the Y-axis direction to extend or shorten the push-pull rod 1. After the lock is fixed, the support rod 3 is extended or shortened, and the push-pull rod 1 is directly pushed, and the probe 6 is used for marking or measurement.

[0032] From the above content, it can be seen that the three-dimensional marking instrument auxiliary device disclosed in the embodiment of the utility model pushes and pulls the push-pull rod 1 in the X\Y\Z axis direction to move the probe 6 to the required spatial position, so that the measurement personnel can directly push and pull the marking instrument at a distance from the marking instrument body by holding the horizontal push-pull rod 1, so that the measurement personnel do not need to walk back and forth over a large range, and can push and pull the added horizontal push-pull rod 1 with one hand to move the body as a whole, and move the cross arm with one hand, so that the probe can quickly contact the measured size and quickly confirm the accuracy of the measurement, thereby reducing the operation intensity while improving the measurement efficiency and accuracy.

[0033] Furthermore, the movement in the X-axis direction is horizontal left-right movement, the movement in the Y-axis direction is horizontal forward-backward movement, and the movement in the Z-axis direction is vertical up-and-down movement perpendicular to the X-axis. The three directions of X\Y\Z axes move perpendicular to each other.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
