[0036] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] This invention provides a mobile, rapid positioning spatial measurement device, comprising:

[0038] The vehicle frame has vertically retractable casters at its bottom.

[0039] At least one lateral V-shaped positioning component and at least one longitudinal V-shaped positioning component are disposed at the bottom of the vehicle frame. When the moving wheel retracts towards the vehicle frame, the vehicle frame is positioned and connected to the ground through the lateral V-shaped positioning component and the longitudinal V-shaped positioning component.

[0040] Multiple instrument support tilting platforms are set on the top of the vehicle frame in the circumferential direction;

[0041] Wireless pendulum angle measuring instrument, which can be detachably connected to the tilt table of the instrument stand;

[0042] An adjustable angle bracket is installed at the center of the top of the vehicle frame, and a spatial position measuring instrument is installed on the adjustable angle bracket;

[0043] The control unit connects to the wireless sway angle measuring instrument and the spatial position measuring instrument.

[0044] Specifically, the spatial measurement device places the wireless sway angle measuring instrument and the spatial position measuring instrument on the top of the vehicle frame. The device is moved quickly via wheels. When the device reaches the measurement position, the wheels are raised, and the vehicle frame is supported by the lateral and longitudinal V-shaped positioning components. This ensures that the vehicle frame is aligned with the reference direction of the object to be measured on the ground, achieving the positioning reference of the measurement device. The wireless sway angle measuring instrument and the spatial position measuring instrument are then adjusted via the control unit and manual adjustment to extend the measurement function of the device to compensate for any deficiencies in the moving axis spatial angle.

[0045] Optionally, the vehicle frame is provided with four support parts, with a support arm on one side of each support part. A transmission lifting screw is screwed vertically onto the support arm, the bottom of the transmission lifting screw is connected to a moving wheel, and an operating handle is provided on the top of the transmission lifting screw.

[0046] Specifically, the vehicle frame is a rectangular frame structure with four support parts at the bottom. Each support part has a support arm welded to its outer side, and a transmission lifting screw is screwed onto the support arm. By operating the operating handle, the moving wheels can be moved vertically. When it is necessary to fix the vehicle frame, the moving wheels are raised above the height of the V-shaped positioning components in the horizontal and vertical directions. The V-shaped positioning components ensure that the vehicle frame is in the reference direction, thus ensuring the accurate positioning of the space measuring device.

[0047] Optionally, two lateral V-shaped positioning components are provided, and the lateral V-shaped positioning components include:

[0048] The upper part of the lateral positioning is fixedly connected to the bottom of the support part, and the bottom surface of the upper part of the lateral positioning is provided with a first V-shaped groove.

[0049] A transverse positioning support is provided below the transverse positioning upper component. The top surface of the transverse positioning support is provided with a first protrusion, which is V-shaped and cooperates with a first V-shaped groove.

[0050] Specifically, the transverse V-shaped positioning assembly includes a transverse positioning upper component on the support and a transverse positioning support on the ground. A first V-shaped groove is formed in the middle of the lower surface of the transverse positioning upper component. The first V-shaped groove is an elongated groove, and its length direction is the transverse direction of the vehicle frame. A first V-shaped protrusion is formed in the middle of the upper surface of the transverse positioning support. The first protrusion is an elongated protrusion. The portions of the transverse positioning upper component located on both sides of the first protrusion are horizontal planes, and the height of the horizontal planes is lower than the inclined portion of the first protrusion. When a downward force is applied to the transverse positioning upper component under the gravity of the vehicle frame, the inner side of the first V-shaped groove fits against the outer side of the first protrusion, ensuring that the first protrusion can be completely embedded in the first V-shaped groove, so that the support is fixed in the reference direction and the vehicle frame is accurately positioned in the reference direction.

[0051] Optionally, two longitudinal V-shaped positioning components are provided, and the longitudinal V-shaped positioning components include:

[0052] The upper component is positioned longitudinally, and its top surface fits against the bottom of the support. The bottom surface of the upper component is provided with a second V-shaped groove, and the length direction of the first V-shaped groove is perpendicular to the length direction of the second V-shaped groove.

[0053] A longitudinal positioning support is provided below the longitudinal positioning upper component. The top surface of the longitudinal positioning support is provided with a second protrusion. The second protrusion is in the shape of a positive V and cooperates with the second V-shaped groove.

[0054] Specifically, the longitudinal V-shaped positioning component includes a longitudinal positioning upper part and a longitudinal positioning support. The longitudinal positioning upper part and the longitudinal positioning support are respectively provided with a second V-shaped groove and a second protrusion. The second V-shaped groove has the same structure as the first V-shaped groove, and the length directions of the grooves are perpendicular to each other. The second protrusion has the same structure as the first protrusion, and the length directions of the protrusions are perpendicular to each other. The longitudinal V-shaped positioning component ensures accurate positioning of the vehicle frame in the longitudinal direction. By setting two longitudinal V-shaped positioning components and a transverse V-shaped positioning component on the support, rapid positioning can be achieved after the vehicle frame is placed on the ground, saving preparation time for measurement. Existing measuring device frames achieve positioning by centering two through holes and inserting pins into the two through holes. Since the through holes need to be set with certain tolerances, positioning deviations are prone to occur. Furthermore, the pin installation operation is time-consuming and labor-intensive, failing to achieve the rapid positioning effect of the transverse V-shaped positioning component and the longitudinal V-shaped positioning component.

[0055] In one embodiment, at least one transverse V-shaped positioning component can be provided on the four support parts of the vehicle frame, and longitudinal V-shaped positioning components can be provided on the remaining legs. Alternatively, the number of positioning components in the two directions can be varied, and the positions of the transverse and longitudinal V-shaped positioning components are not restricted. V-shaped positioning components in the same direction can be arranged in a way that is cross or adjacent to each other. All of these methods can ensure that the vehicle frame can be quickly positioned when it lands on the ground through the V-shaped positioning components.

[0056] Optionally, the upper part for lateral positioning and the upper part for longitudinal positioning each have two bolt through holes. The bolt through holes are symmetrically arranged on both sides of the first V-shaped groove and the second V-shaped groove along the vertical direction. The upper part for lateral positioning is connected to the two support parts by the first set of bolts, and the upper part for longitudinal positioning is connected to the other two support parts by the second set of bolts.

[0057] Specifically, bolt through holes are provided on the lateral and longitudinal positioning components. The positioning components are connected to the support of the vehicle frame by bolts, ensuring that the bolts are not exposed on the protruding positions relative to the lower surface of the positioning components. This allows the V-shaped grooves and protrusions on the lateral and longitudinal sides to be fully engaged without affecting the positioning accuracy of the vehicle frame.

[0058] Optionally, the lateral positioning support and the longitudinal positioning support are respectively connected to the ground, and the combination of the first protrusion and the second protrusion can make the vehicle frame be in a specified spatial position.

[0059] Specifically, the lateral and longitudinal positioning supports are fixed on the ground, ensuring that the height of the first and second protrusions is set vertically and the width of the first and second protrusions is set horizontally. This ensures that the two positioning supports conform to the positioning reference. After the vehicle frame rests on the lateral and longitudinal positioning supports, a quick positioning effect can be achieved. The specified spatial position is the positioning coordinate reference of the object to be measured. For some objects to be measured, the positioning coordinate reference is consistent with the horizontal and vertical directions, while for others, it forms a certain angle with the horizontal and vertical directions, which can be 5°, 7°, or any angle. As long as the height and width directions of the vehicle frame are adjusted to be consistent with the positioning coordinate reference of the object to be measured, it is acceptable.

[0060] In another embodiment, the lateral positioning support and the longitudinal positioning support can be mounted on a support platform. The bottom of the support platform is provided with a device that can adjust the horizontal angle. When the space measuring device needs to work, the support platform is placed around the object to be calibrated, and the support platform is adjusted to be horizontal by the horizontal angle device. This enables the lateral positioning support and the longitudinal positioning support to be in the positioning reference. Then, the upper lateral positioning component and the upper longitudinal positioning component are placed on top, which enables the rapid positioning of the vehicle frame.

[0061] Optionally, four instrument bracket tilting platforms are provided. The fixed surface of the instrument bracket tilting platform is connected to the top of the vehicle frame. The mounting surface of the instrument bracket tilting platform forms a certain angle with the horizontal direction. A certain angle is formed between the instrument bracket tilting platforms. The mounting surface of the instrument bracket tilting platform is connected to the wireless swing angle measuring instrument through a quick-change connecting plate.

[0062] Specifically, the instrument bracket tilting platform is set on the vehicle frame, and a ring is set around the outer perimeter of the vehicle frame to ensure that the wireless swing angle measuring instrument installed on all instrument bracket tilting platforms covers an angle of 360°. When it is necessary to measure the object to be calibrated in a certain direction, the wireless swing angle measuring instrument is installed on the instrument bracket tilting platform facing that direction. Then, the probe of the wireless swing angle measuring instrument is adjusted by the control unit to adjust the probe to a suitable rotation angle for measurement compensation of the object to be calibrated.

[0063] In one embodiment, the wireless swing angle measuring instrument can be a wireless angle measuring instrument or a rotation angle measuring instrument.

[0064] Optionally, the quick-change connecting plate has multiple mounting holes and one positioning hole along its circumference. The quick-change connecting plate is connected to the mounting surface of the instrument bracket tilting stage through the mounting holes, and the quick-change connecting plate is positioned and connected to the mounting surface of the instrument bracket tilting stage through the positioning hole and the circumferential positioning pin.

[0065] Specifically, the quick-change connecting plate is connected to the instrument bracket tilting stage through mounting holes and bolts, enabling the wireless swing angle measuring instrument to quickly switch angle positions. The wireless swing angle measuring instrument can be quickly installed on the reference mounting angle through positioning holes and circumferential positioning pins, realizing rapid measurement and multiple measurements. This facilitates multiple measurements before and after use of the processing equipment, enabling measurement calibration compensation and improving the positioning accuracy of the processing equipment.

[0066] Optionally, the swingable support includes a base and a fixing plate. The base is connected to the top of the vehicle frame, and the base is rotatably connected to the lower side of the fixing plate via a pivot. The fixing plate rotates along the pivot. The base is provided with equally spaced connecting holes, and the base can be connected to change the angle direction through the equally spaced connecting holes. The upper side of the fixing plate is connected to a spatial position measuring instrument.

[0067] Specifically, the spatial position measuring instrument is used for spatial accuracy measurement and compensation of high-precision CNC equipment, such as high-precision multi-axis CNC machine tools. It solves the problem of expensive instruments for multiple devices requiring accuracy compensation and the need to share measuring instruments for transportation when the number of instruments is small. Compared with traditional CNC equipment using measurement calibration and compensation instruments that can only perform compensation once before leaving the factory, the spatial position measuring instrument and wireless tilt angle measuring instrument can perform measurement calibration and compensation multiple times before and after use of the processing equipment. The spatial position measuring instrument can perform spatial position measurement and compensation of the equipment under test, while the wireless tilt angle measuring instrument can measure the rotation angle of the processing equipment. By centrally arranging the spatial position measuring instrument and adjusting the tilt angle support as needed, and combining it with the wireless tilt angle measuring instrument that can flexibly adjust the measurement orientation, the function of expanding the spatial angle of the moving axis of the measuring device can be realized.

[0068] Optionally, a pair of trolley handles are provided on the vehicle frame.

[0069] Specifically, the vehicle frame can be moved using the trolley handle, making it easy to operate and control.
