[0030] Embodiment 1:

[0031] like Figure 1-4 As shown, the utility model provides an αβ tilting platform for chip testing, including a plurality of adjustment devices; the plurality of adjustment devices are stacked and installed together in sequence; specifically, the number of adjustment devices is selected according to needs, and adjacent adjustment devices are detachably connected together by bolts; each adjustment device includes two adjustment units 100; the two adjustment units 100 are stacked and installed together in sequence; the two adjustment units 100 each include a fixing seat 110, an adjustment seat 120 and an adjustment assembly 130; the top of the fixing seat 110 has a fixing arc surface 111 running through both ends; in the two adjustment units 100, the adjustment seat 120 at the top is provided with a fixing arc surface 111 running through both ends; The top of the adjustment seat 120 in the unit 100 is used to install the chip; the bottom end of the adjustment seat 120 has a movable arc surface 121 running through both ends; the movable arc surface 121 is coaxial with the fixed arc surface 111; the adjustment seat 120 is slidably connected to the fixed arc surface 111 through the movable arc surface 121; the adjustment component 130 is arranged inside the fixed seat 110; wherein, the adjustment component 130 is used to drive the adjustment seat 120 to slide along the fixed arc surface 111 to tilt the adjustment seat 120; in the two adjustment units 100, the sliding directions of the two adjustment seats 120 are perpendicular to each other.

[0032] Specifically, among two adjacent adjustment units 100 , the upper adjustment unit 100 has a fixing seat 110 connected to the adjustment seat 120 of the lower adjustment unit 100 by means of bolts.

[0033] The principle and beneficial effects of the above technical solution:

[0034] In a specific implementation, the chip is installed on the adjustment seat 120 in the upper adjustment unit 100, and the adjustment component 130 in the lower adjustment unit 100 is adjusted first, so as to drive the adjustment seat 120 to slide along the fixed arc surface 111, and then drive the upper adjustment unit 100 to follow the movement, so that the chip is adjusted to a tilted state in one degree of freedom. Then, the adjustment component 130 is stopped and the adjustment component 130 in the upper adjustment unit 100 is adjusted, so that the adjustment seat 120 with the chip installed can slide along the fixed arc surface 111. Since the sliding directions of the two adjustment seats 120 are perpendicular to each other, the chip can be adjusted to a tilted state in another degree of freedom.

[0035] By adjusting the two adjustment components 130, the chip can be adjusted with two degrees of freedom to achieve a tilted state in two directions. This adjustment method is more flexible and can meet more testing requirements under tilted states. Through the staged adjustment process, the tilt angle of the chip can be more finely controlled, and the stability and accuracy of the adjustment process can be ensured. This helps to obtain accurate and reliable test results.

[0036] In this embodiment, Figure 3 As shown, the adjustment component 130 includes an adjustment shaft 131 and an adjustment tube 132; an adjustment groove 112 is opened inside the fixed seat 110 and penetrates to the fixed arc surface 111; the adjustment shaft 131 is rotatably connected in the adjustment groove 112; the adjustment shaft 131 is horizontally arranged along the sliding direction of the adjustment seat 120; the adjustment tube 132 is coaxially fixedly sleeved on the adjustment shaft 131; there is a gap between the adjustment tube 132 and the side wall of the adjustment groove 112, so as to ensure that when the adjustment shaft 131 rotates, the adjustment tube 132 can follow the rotation; the peripheral side of the adjustment tube 132 is threadedly connected to the movable arc surface 121; specifically, the peripheral side of the adjustment tube 132 and the movable arc surface 121 are both machined with threads; wherein, the adjustment shaft 131 is used to drive the adjustment tube 132 to rotate so as to slide along the fixed arc surface 111 with the adjustment seat 120.

[0037] Specifically, Figure 2 , 3 As shown, both ends of the adjustment slot 112 are provided with rotating holes that penetrate to both ends of the fixing seat 110; bearings are coaxially fixedly installed in the two rotating holes; both ends of the adjustment shaft 131 are coaxially fixedly connected to the inner rings of the corresponding bearings; both ends of the fixing seat 110 are respectively connected to the side seats 113 by screws; the two side seats 113 are provided with side holes coaxial with the rotating holes; both ends of the adjustment shaft 131 extend into the corresponding side holes; rotating handles 133 are installed at both ends of the adjustment shaft 131; the diameters of the two rotating handles 133 are larger than the diameter of the adjustment shaft 131, and the rotating handles 133 are used to facilitate the rotation of the adjustment shaft 131; at the same time, the rotating handles 133 can limit the position of the adjustment shaft 131 to prevent the adjustment shaft 131 from sliding in the horizontal direction and leaving the adjustment slot 112.

[0038] The principle and beneficial effects of the above technical solution:

[0039] During specific implementation, by twisting the rotating handle 133, the adjustment tube 132 can be driven to rotate through the adjustment shaft 131. Since the adjustment tube and the movable arc surface 121 are threadedly connected, the adjustment seat 120 can be driven to slide along the fixed arc surface 111, so that the adjustment seat 120 can be adjusted to a tilted state. By setting the adjustment component 130, the chip can be adjusted to a double degree of freedom, so that it can reach a tilted state in two directions. This adjustment method is more flexible and can meet more testing requirements under tilted states. Through the staged adjustment process, the tilt angle of the chip can be more finely controlled, and the stability and accuracy during the adjustment process can be ensured. This helps to obtain accurate and reliable test results.

[0040] Embodiment 2:

[0041] This embodiment is based on the first embodiment. Figure 3 , 4 As shown, a limiting arc groove 114 is formed on the fixed arc surface 111; the limiting arc groove 114 is coaxial with the fixed arc surface 111; a coaxial limiting arc strip 122 is integrally formed on the movable arc surface 121; the limiting arc strip 122 is slidably connected to the limiting arc groove 114.

[0042] Specifically, the number of the limiting arc grooves 114 and the limiting arc bars 122 are both two; the two limiting arc grooves 114 are respectively close to the two sides of the fixed seat 110. Through the setting of the two limiting arc grooves 114 and the limiting arc bars 122, double limiting can be provided, thereby enhancing the stability and safety of the fixed seat 110 and avoiding shaking or instability during sliding.

[0043] The principle and beneficial effects of the above technical solution:

[0044] In a specific implementation, when the adjustment shaft 131 is turned, the adjustment seat 120 will slide along the fixed arc surface 111, and the setting of the limiting arc groove 114 and the limiting arc strip 122 can limit the sliding direction of the adjustment seat 120, so that it can slide completely along the fixed arc surface 111, thereby preventing the adjustment seat 120 from leaving the fixed seat 110 during the sliding process.

[0045] The arrangement of the limiting arc groove 114 and the limiting arc strip 122 ensures the stability of the adjustment seat 120 during the sliding process. They can effectively limit the sliding range of the adjustment seat 120 and avoid deviation from the fixed arc surface 111, thereby ensuring the stability and accuracy of the adjustment process.

[0046] In this embodiment, Figure 4 As shown, a displacement arc bar 123 is coaxially fixed on the movable arc surface 121; the displacement arc bar 123 is integrally formed on the movable arc surface 121, and the integrally formed displacement arc bar 123 can maintain consistent materials and structures during the manufacturing process, thereby improving the stability of the entire component; the displacement arc bar 123 is located between the two limiting arc bars 122; the bottom side of the displacement arc bar 123 has a threaded arc groove 124; the threaded arc groove 124 is coaxial with the displacement arc bar 123; the threaded arc groove 124 has a threaded surface; the displacement arc bar 123 is threadedly connected to the adjustment tube 132 through the threaded arc groove 124.

[0047] The principle and beneficial effects of the above technical solution:

[0048] By providing a displacement arc strip 123 and opening a threaded arc groove 124 with threads, the adjustment seat 120 can be in a threaded connection with the adjustment tube 132 through the threaded arc groove 124 during the sliding process. At the same time, the adjustment tube 132 will not leave the threaded arc groove 124 during the rotation process, so that the movement of the adjustment seat 120 can be further guided, thereby enhancing the movement guidance of the adjustment seat 120 and making the adjustment process more stable and reliable.

[0049] The setting of the threaded arc groove 124 enables the adjustment seat 120 to form a threaded connection with the adjustment tube 132 during the sliding process, which can enhance the movement guidance of the adjustment seat 120, ensure that the adjustment seat 120 moves along a predetermined trajectory, and improve the stability and reliability of the adjustment; the threaded connection can effectively reduce the deviation and swing generated by the adjustment seat 120 during the sliding process, making the movement of the adjustment seat more stable and precise, helping to maintain the correct positional relationship between the adjustment seat and other components, and improving the accuracy of the adjustment.

[0050] Embodiment three:

[0051] This embodiment is based on the first or second embodiment. Figure 2 , 4 As shown, the adjustment unit 100 located at the top also includes a tightening assembly 140; specifically, the tightening assembly 140 is located on the adjustment unit 100 at the top; the tightening assembly 140 includes a tightening plate 141, a tightening block 142 and a tightening member 143; the tightening plate 141 is connected to the vertical side wall of the adjustment arc block; the tightening plate 141 is horizontally arranged along the sliding direction of the adjustment arc block; the tightening plate 141 is provided with a tightening arc groove 144 coaxial with the moving arc surface 121; there is a gap between the tightening plate 141 and the vertical side wall; the tightening block 142 is connected to the vertical side wall of the fixed seat 110; the tightening block 142 is located in the gap; the back of the tightening block 142 The side away from the fixed seat 110 contacts with the side of the clamping plate 141 close to the adjustment seat 120; the clamping piece 143 is threaded through the clamping block 142, and one end of the clamping piece 143 is clamped against the vertical side wall; a part of the clamping piece 143 is clamped against the side of the clamping plate 141 away from the adjustment seat 120; the clamping piece 143 is a three-step stepped screw; the screw includes three connecting ends with successively decreasing diameters; in the stepped screw, the connecting end with the smallest diameter is threadedly connected to the clamping arc groove 144 and threaded through the clamping block 142, and is clamped against the vertical side wall of the fixed seat 110; in the stepped screw, the connecting end close to the end with the smallest diameter is clamped against the clamping plate 141.

[0052] Specifically, two abutting tubes 145 are connected to the side wall of the adjustment seat 120; the abutting plate 141 is fixed by screws passing through the abutting plate 141 and being threadedly connected in the abutting tubes 145, and the abutting tubes 145 provide additional support points, so that the abutting plate 141 can be more firmly fixed to the side wall of the adjustment seat 120. The threaded connection between the screws and the abutting tubes 145 ensures that the connection between the abutting plate 141 and the adjustment seat 120 is firm and reliable, and is not easy to loosen or fall off.

[0053] The principle and beneficial effects of the above technical solution:

[0054] The abutting piece 143 is always connected to the abutting block 142. When the adjustment seat 120 moves to the predetermined position, the abutting plate 141 is driven to move synchronously through the abutting tube 145. Once the adjustment seat 120 reaches the predetermined position, the abutting piece 143 only needs to be turned, and the connection end of the end with the smallest diameter can abut against the adjustment seat 120. In this way, the adjustment seat 120 can maintain the tilted state after the adjustment position to avoid deviation or shaking.

[0055] In this embodiment, Figure 2 As shown, a side of the adjustment seat 120 close to the abutting plate 141 is in sliding contact with the abutting block 142 .

[0056] Specifically, the vertical side wall of the limiting arc strip 122 close to one side of the abutting plate 141 is in sliding contact with the side wall of the abutting block 142 .

[0057] The principle and beneficial effects of the above technical solution:

[0058] In specific implementation, the cooperation of the limiting arc strip 122 and the abutting block 142 ensures the stability of the adjustment seat 120 during the sliding process, prevents swinging or inaccurate position adjustment caused by unstable sliding, thereby enhancing the stability of the adjustment seat 120; the design of the limiting arc strip 122 and the abutting block 142 ensures that the adjustment seat 120 is effectively limited and fixed during the sliding process, preventing swinging or inaccurate position. In this way, the stability of the adjustment seat 120 can be maintained, ensuring that it remains stable in the predetermined position, and improving the reliability of the system.

[0059] Embodiment 4:

Figure 5-7As shown, in the adjustment unit 100 located below, a guide arc strip 150 is coaxially provided on the fixed arc surface 111 and is integrally processed; a guide arc groove 160 is coaxially opened on the movable arc surface 121; the guide arc strip 150 and the guide arc groove 160 are coaxial; in the guide arc groove 160, the angles between the two opposite side walls and the other side wall are both acute angles; the guide arc strip 150 is slidably connected in the guide arc groove 160; the upper part of the adjustment groove 112 passes through to the top side of the guide arc strip 150; the circumferential side of the adjustment tube 132 is located outside the adjustment groove 112; threads are processed on the circumferential side of the adjustment tube 132 and the movable arc surface 121; the adjustment tube 132 is threadedly connected to the movable arc surface 121; the rotating handle 133 at one end of the adjustment shaft 131 is cylindrical and is rotatably connected in the rotating hole; the other end of the adjustment shaft 131 is rotatably connected in another rotating hole, and a part of the rotating handle 133 is located outside the fixed seat 110.

[0061] The principle and beneficial effects of the above technical solution:

[0062] During specific implementation, the adjustment ring is driven to rotate by rotating the handle 133, thereby driving the adjustment tube 132 to rotate, and then the adjustment seat 120 can slide along the fixed arc surface 111 under the action of the thread, so that the adjustment seat 120 moves to an inclined state; at the same time, in the guide arc groove 160, the angles between the two opposite side walls and the other side wall are both acute angles, which enables the two sides of the guide arc bar 150 to be confined in the guide arc groove 160, so that the movement of the adjustment seat 120 can be guided, preventing swinging or inaccurate position adjustment caused by unstable sliding, thereby enhancing the stability of the adjustment seat 120.

[0063] In this embodiment, Figure 5-7 As shown, a tightening hole is opened on the vertical side wall of the adjustment seat 120; the tightening hole horizontally penetrates into the guide arc groove 160; a tightening member 170 is threadedly connected to the tightening hole; the arrangement direction of the tightening member 170 is perpendicular to the sliding direction of the adjustment seat 120; one end of the tightening member 170 extends into the guide arc groove 160 and is tightly pressed against the guide arc bar 150.

[0065] The principle and beneficial effects of the above technical solution:

[0066] In specific implementation, when the adjustment seat 120 moves to the predetermined position, the tightening piece 170 is screwed so that one end of the tightening piece 170 is threadedly connected to the tightening hole, thereby pushing the deformed arc plate 180 in the direction of the guide arc bar 150 until the deformed arc plate 180 is tightly pressed against the guide arc bar 150, so that the adjustment seat 120 can maintain the inclined state after the adjustment position to avoid displacement or shaking.

[0067] By tightening the tightening member 170, the deformable arc plate 180 can be firmly pressed against the guide arc bar 150, ensuring that the adjustment seat 120 maintains a predetermined tilt state. This mechanical locking method can effectively prevent the adjustment seat 120 from deflecting or shaking, thereby improving the stability and reliability of the entire system. At the same time, it is achieved by simply tightening the tightening member 170, which is easy and convenient to operate. No additional tools or complicated steps are required, and locking can be completed by simply turning the tightening member, saving operation time and labor costs.
