Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to an adjustable supporting platform. Background Art

[0002] During the actual operation and application of vehicle-mounted laser turntables, a significant challenge is that the ground conditions at the vehicle's docking location are often less than ideally flat. Due to variations in natural topography, varying degrees of soil compaction, and the long-term pressure of the vehicle's weight on the ground, the surface often becomes uneven, or even partially concave due to the weight. This unstable ground surface directly impacts the laser turntable mounted on the vehicle, particularly the levelness of its base, which is easily disturbed.

[0003] Specifically, when the support surface at the bottom of the laser turntable is non-horizontal, the turntable's overall stability and accuracy are significantly compromised. During operation, this non-ideal state severely restricts the turntable's pitch angle, preventing it from freely adjusting to the preset calibration value. This limited pitch angle not only reduces the operating range but can also trigger a series of chain reactions, such as increased scanning blind spots and decreased data accuracy, ultimately affecting the performance and efficiency of the entire laser operation system. Utility Model Content

[0004] The utility model aims to provide an adjustable support platform to solve the problem in the prior art that the horizontal state of the bottom of a vehicle-mounted laser turntable is disturbed by external influences, which limits the working performance and efficiency of the laser turntable.

[0007] Preferably, a ball bearing is provided between the support member and the adjusting member, the ball bearing comprising an inner ring member and an outer ring member, the inner ring member having an outer wall with an arc surface, the inner side wall of the outer ring member having an arc surface matching the outer side wall of the inner ring member, the inner ring member being universally rotatably connected within the outer ring member, one of the inner ring member and the outer ring member being fixedly connected to the adjusting member, and the other being fixedly connected to the support member.

[0008] Preferably, a plurality of guide grooves are provided along the chassis, and the lengthwise extension lines of the plurality of guide grooves intersect at the center point of the chassis, and the bottom corner pieces are slidably connected to the guide grooves in a one-to-one correspondence.

[0009] Preferably, a limiting groove is provided at the bottom of the guide groove, and the limiting groove is arranged parallel to the guide groove.

[0023] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figure 1 As shown in the drawings, an adjustable support platform for adjusting the levelness of a vehicle-mounted laser turntable comprises an adapter disc 1, a base disc 2 and an adjusting assembly 3. The adapter disc 1 is movably connected to the base disc 2 through at least three groups of adjusting assemblies 3. The length of the adjusting assembly 3 is adjusted to adjust the inclination angle of the adapter disc 1 and the base disc 2. Even if the base disc 2 is in an inclined state, the adapter disc 1 can be adjusted to a horizontal state. A turntable base 4 is fixed on the top of the adapter disc 1 for carrying the vehicle-mounted laser, which ensures that the laser can be kept in a horizontal state for operation.

[0027] As shown in the drawings, Figure 2 and Figure 3 The adjusting assembly 3 comprises a support piece 31, an adjusting piece 32 and a bottom corner piece 33, which are movably connected in sequence along a first direction. In this embodiment, the first direction is the vertical direction, that is, the support piece 31, the adjusting piece 32 and the bottom corner piece 33 are movably connected in sequence from top to bottom along the vertical direction. One end of the support piece 31 is fixed to the adapter disc 1, and the other end of the support piece 31 is movably connected to the adjusting piece 32.

[0028] Specifically, the bottom of the adapter disc 1 is provided with a plurality of positioning discs 21, which are distributed in a circumferential array around the center of the adapter disc 1. The top of the support piece 31 is provided with a positioning groove 311, and the positioning disc 21 is connected to the positioning groove 311 of the support piece 31 in an interference fit. Through the above structure, the plurality of adjusting assemblies 3 can be positioned, that is, the plurality of adjusting assemblies 3 are distributed in a circumferential array around the center of the adapter disc 1. The plurality of adjusting assemblies 3 can jointly bear the weight of the adapter disc 1 and the objects carried thereby, thereby dispersing the pressure and reducing the situation of excessive stress on a single point, which helps to maintain the horizontal state of the adapter disc 1 and avoid tilting or shaking of the adapter disc 1, thereby improving the overall stability.

[0029] A ball bearing 34 is arranged between the support piece 31 and the adjusting piece 32, and the adjusting piece 32 is movably connected to the support piece 31 through the ball bearing 34. The ball bearing 34 comprises an inner ring 341 and an outer ring 342, the inner ring 341 is movably connected to the inner ring 341, the outer ring 342 has a circular arc outer side wall, and the inner side wall of the outer ring 342 has a circular arc surface matched with the outer side wall of the inner ring 341. The inner ring 341 is movably connected to the outer ring 342, preferably, the outer side wall of the inner ring 341 and the inner side wall of the outer ring 342 are spherical surfaces, so that the rotation of the outer ring 342 and the inner ring 341 is more flexible.

[0030] One of the inner ring member 341 and the outer ring member 342 is fixedly connected to the adjustment member 32, and the other is fixedly connected to the support member 31. Preferably, the inner ring member 341 is fixedly connected to the support member 31, and the outer ring member 342 is fixedly connected to the adjustment member 32. More preferably, the support member 31 is inserted into the inner ring member 341, and the inner side wall of the support member 31 is fixedly connected to the outer side wall of the inner ring member 341 by an interference fit, and the outer ring member 342 is inserted into the adjustment member 32, and the inner side wall of the adjustment member 32 is fixedly connected to the outer side wall of the outer ring member 342 by an interference fit. Since the support member 31 is fixedly connected to the adapter plate 1, that is, the inner ring member 341 is relatively stationary, the adjustment member 32 rotates relative to the inner ring member 341 via the outer ring member 342, thereby realizing a universal rotation connection between the support member 31 and the adjustment member 32.

[0031] The adjustment member 32 is threadedly connected to the bottom corner fitting 33 along a first direction. One of the adjustment member 32 and the bottom corner fitting 33 is provided with an internal thread, and the other is provided with an external thread corresponding to the internal thread. Preferably, the internal thread is provided in the bottom corner fitting 33, and the corresponding external thread is provided on the outer wall of the adjustment member 32. This allows an operator to rotate the adjustment member 32 by hand to adjust the depth of the threaded engagement between the adjustment member 32 and the bottom corner fitting 33. In other words, the operator can adjust the length of the connection overlap between the adjustment member 32 and the bottom corner fitting 33 in the first direction, thereby changing the total length of the adjustment member 32 and the bottom corner fitting 33 along the first direction to control the elevation angle of the adapter plate 1 relative to the chassis 2.

[0032] Several guide slots 22 are formed along the chassis 2. These slots 22 correspond one-to-one with the positioning plate 21 along the first direction, that is, the slots 22 are arranged in an array around the central circumference of the chassis 2. The longitudinal extensions of the slots 22 converge at the center point of the chassis 2. The bottom corner pieces 33 are slidably connected to the slots 22 in a one-to-one manner. Specifically, the slots 22 are waist-shaped slots, and the bottom corner pieces 33 abut against the inner walls of the slots 22 on both sides. That is, the bottom corner pieces 33 abut against the inner walls of the slots 22 in the width direction. The bottom corner pieces 33 only slide along the length of the slots 22, preventing the bottom corner pieces 33 from shaking during the sliding process. This reduces the adverse effects on the laser during the adjustment of the adapter plate 1.

[0033] like Figure 4As shown, the bottom of the guide groove 22 is formed with a plurality of limiting grooves 23 and a plurality of receiving grooves 24. The receiving grooves 24 are recessed inward from the bottom of the chassis 2, and the limiting grooves 23 connect the receiving grooves 24 and the guide groove 22. Both the limiting grooves 23 and the receiving grooves 24 are waist-shaped grooves and are arranged parallel to the guide groove 22. A bolt 35 is threadedly connected to the end face of the bottom angle fitting 33 facing away from the adjustment member 32. The bolt 35 includes a screw and a bolt head. The screw is threadedly connected to the bottom angle fitting 33 and slides within the limiting groove 23. The bolt head is located within the receiving groove 24, and the radial dimension of the bolt head is greater than the width of the receiving groove 24. When the bolt 35 is tightened, the bolt head abuts against the bottom surface of the receiving groove 24, and the bottom angle fitting 33 abuts against the bottom surface of the guide groove 22, thereby locking the bottom angle fitting 33 to the chassis 2.

[0034] In this embodiment, there are three groups of adjustment components 3, which are distributed in a circular array and fixedly connected to the bottom of the adapter plate 1. The three groups of adjustment components 3 cooperate to adjust the elevation angle of the adapter plate 1 relative to the chassis 2. Preferably, the three groups of adjustment components 3 form an equilateral triangle.

[0035] Principle: When the adapter tray 1 is tilted, the bolts 35 of two adjustment assemblies 3 are tightened, while the bolts 35 of one adjustment assembly 3 are loosened. The adjusting members 32 of the adjustment assemblies 3 with loose bolts 35 are rotated, gradually extending from the bottom corner fittings 33, thereby lifting the adapter tray 1 and causing it to rotate. During this process, the ball bearings 34 of the three adjustment members 32 rotate passively, causing the bottom corner fittings 33 to slide within the guide grooves 22. Subsequently, the bolts 35 are tightened, and the three adjustment assemblies 3 are adjusted sequentially, allowing the adapter tray 1 to be adjusted to a horizontal position.

[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
