Description

Technical Field

[0001] The utility model belongs to the technical field of jigs and relates to a clamping jig. Background Art

[0002] In modern manufacturing, product quality is regarded as one of the core elements of an enterprise's competitiveness. To ensure that the precision products produced can meet strict standards and specifications, almost all high-end products need to go through a series of inspections and verifications after the production process. This process is not only a confirmation of the product performance but also a test of the effectiveness of the production quality control system.

[0003] For example, a patent for invention with an application number of CN201810940518.1 provides a multi-axis detection platform, including an installation base. The upper surface of the installation base is movably connected with a slider. The top of the slider is installed with a main installation column. The outside of the main installation column is installed with a first adjustment component and a second adjustment component. The first adjustment component includes a bracket support plate, a lateral positioning plate, a triangular reinforcing rib, a V-shaped bracket, and a bracket mounting plate. The second adjustment component includes a dovetail seat, a horizontal beam, a mounting plate, and an adjustment table. The multi-axis detection platform proposed by the present invention can adjust the relative position of the slider by rotating the slider adjustment bolt. The auxiliary lifting component can be used to adjust the height of the V-shaped bracket. When the adjustment bolt is rotated, the height of the mounting plate can be adjusted within a certain range. There are many components that can be adjusted in the whole device, enabling the device to meet different usage environments. At the same time, the range that the V-shaped bracket can support can also be easily adjusted, greatly improving the applicable range and having good applicability.

[0004] In summary, although some existing technical solutions solve the problem of product detection, due to the fewer adjustment directions of the existing detection platforms, there is still a problem that the full-range precise movement of the product to be measured cannot be achieved, and there is a large room for improvement.

[0038] Among them, the second moving component 4 includes a second moving platform 41 and a second moving driving component 42. The second moving platform 41 is connected to the second moving driving component 42, and the second moving driving component 42 is connected to the first moving platform 31. The second moving driving component 42 can drive the second moving platform 41 to move, and the moving direction of the first moving platform 31 is perpendicular to the moving direction of the second moving platform 41.

[0039] Among them, the clamping component 5 includes a first clamping member 51 and a fixing member. The first clamping member 51 is connected to the fixing member, and the fixing member is connected to the second moving platform 41.

[0040] Specifically, the object to be measured is fixed on the first clamping member 51. The first clamping member 51 can achieve relative movement with respect to the second moving platform 41 through the clamping component 5. The second moving platform 41 moves relative to the first moving platform 31 through the second moving component 4. The first moving platform 31 moves relative to the lifting platform 21 through the first moving component 3. The moving directions of the first moving platform 31 and the second moving platform 41 are perpendicular to each other. The lifting platform 21 can adjust its height relative to the base 1 through the lifting component 2.

[0041] In this embodiment, after the object to be measured is fixed on the first clamping member 51, the clamping component 5, the second moving platform, the first moving platform, and the lifting platform 21 provide the object to be measured with comprehensive degrees of freedom of movement, ensuring that the required precise position control can be achieved in various testing and processing scenarios.

[0042] As Figures 1 - 3 shown, on the basis of the above embodiment, the lifting driving component 22 includes a first connecting portion 221, a second connecting portion 222, and a lifting driving element 223.

One end of the first connecting portion 221 is rotatably connected to the base 1. A first slider 224 is provided at the other end of the first connecting portion 221. The first slider 224 is slidably connected to the lifting platform 21. One end of the second connecting portion 222 is rotatably connected to the lifting platform 21. A second slider 225 is provided at the other end of the second connecting portion 222. The second slider 225 is slidably connected to the base 1. The lifting driving element 223 is connected to the first slider 224 and can drive the first slider 224 to approach or move away from the end of the second connecting portion 222 that is rotatably connected to the lifting platform 21.

[0043] Specifically, the first connecting portion 221 and the second connecting portion 222 are connected to form a scissor structure. When the lifting drive element 223 drives the first slider 224 to approach one end of the second connecting portion 222 that is rotatably connected to the lifting platform 21, the gap between the first connecting portion 221 and the second connecting portion 222 becomes smaller, thereby raising the height of the lifting platform 21. When the lifting drive element 223 drives the first slider 224 to move away from one end of the second connecting portion 222 that is rotatably connected to the lifting platform 21, the gap between the first connecting portion 221 and the second connecting portion 222 becomes larger, thereby lowering the height of the lifting platform 21.

[0044] In this embodiment, the stretching and folding process of the scissor structure is intuitive and easy to operate. By driving only one connecting rod, the entire structure can be unfolded or folded according to a predetermined path without a complex control program or additional auxiliary tools. When the structure is completely folded, all the connecting rods almost completely overlap, greatly reducing the occupied space.

[0046] In this embodiment, when the first slider 224 and the second slider 225 slide in the first sliding groove 2111 and the second sliding groove 111 respectively, they can contact both ends of the first fixing block 211 and the second fixing block 11, thereby preventing the first slider 224 and the second slider 225 from falling off and restricting the moving distance of the first slider 224 and the second slider 225, and further controlling the lifting range of the lifting platform 21.

[0047] As Figures 1 - 3 shown, based on the above embodiment, the lifting drive element 223 includes a first rotating shaft 2231 and a first handle 2232.

[0055] In this embodiment, the distance between the fourth fixing block 212 and the third fixing block 311 is controlled by means of a threaded connection. By utilizing the self-locking property and precision of the thread, a very high positioning accuracy can be achieved, and the overall distance between the fourth fixing block 212 and the third fixing block 311 will not change due to slight vibrations.

The second mobile driving assembly 42 can drive the fifth fixing block 411 to approach or move away from the sixth fixing block 312, thereby realizing the relative movement between the second mobile station 41 and the first mobile station 31.

[0058] In this embodiment, by precisely controlling the movement of the sixth fixing block 312 through the second mobile driving assembly 42, a smooth and controllable relative movement between the second mobile station 41 and the first mobile station 31 can be achieved.

[0059] As Figures 1 - 3 shown, based on the above embodiment, the second mobile driving assembly 42 includes a third rotating shaft 421 and a third handle 422.

[0060] Specifically, rotate the third handle 422 to drive the third rotating shaft 421 to rotate relative to the fifth fixing block 411. The fifth threaded portion 4211 on the third rotating shaft 421 is connected to the sixth threaded portion on the sixth fixing block 312, thereby driving the sixth fixing block 312 to approach or move away from the fifth fixing block 411.

[0061] In this embodiment, the distance between the sixth fixing block 312 and the fifth fixing block 411 is controlled by means of a threaded connection. By utilizing the self-locking property and precision of the thread, a very high positioning accuracy can be achieved, and the overall distance between the sixth fixing block 312 and the fifth fixing block 411 will not change due to slight vibrations.
