Description

Technical Field

[0001] The utility model relates to the technical field of crystal oscillator detection devices, in particular to a crystal oscillator performance detection device. Background Art

[0002] Crystal oscillators use a crystal that can convert electrical energy and mechanical energy into each other. When working in a resonant state, they can provide stable and accurate single-frequency oscillation. Crystal oscillators are often connected to circuits such as motherboards, south bridges, and sound cards. Crystal oscillators can be likened to the "heartbeat" generator of each board. If there is a problem with the "heartbeat" of the main card, it will definitely cause failures in other circuits.

[0003] The existing authorization announcement number CN212947381U belongs to the technical field of crystal oscillator detection devices, and in particular is a crystal oscillator high-efficiency detection device, including a base, the top of the base is fixedly connected to a side plate, the top of the side plate is fixedly connected to a top plate, the bottom of the top plate is fixedly connected to a hydraulic cylinder, and the bottom of the hydraulic cylinder is fixedly connected to a movable plate.

[0004] Although the above-mentioned patent has many advantages, in actual use, it is found that the detection needle can only move left and right above the crystal oscillator, but cannot move forward and backward, and the degree of freedom is limited. When the area that the crystal oscillator needs to detect is located in front of or behind the detection needle, the detection needle is not easy to move. Therefore, it is necessary to develop a crystal oscillator performance detection device. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-Figure 5 , which shows a schematic diagram of the structure of a crystal oscillator performance detection device of the utility model, please refer to Figure 1-Figure 5 , a crystal oscillator performance detection device is introduced in detail.

[0031] A crystal oscillator performance detection device includes a base 100, mounting plates 110 are arranged on both sides of the top of the base 100, a horizontal rotating drum 120 is arranged to rotate near one side of the two mounting plates 110, and a clamping assembly for mounting the crystal oscillator is symmetrically arranged at one end of the two rotating drums 120;

[0032] A worm gear 200 is arranged on the outer side of the rotating drum 120, and a side plate 210 is arranged on the side wall of the mounting plate 110 below the worm gear 200. A driving rod 220 is rotatably arranged on the side wall of the side plate 210, and a worm 230 meshing with the worm gear 200 is arranged on the rod body of the driving rod 220. The lead angle of the worm 230 is smaller than the equivalent friction between the meshing gear teeth of the worm gear 200, and reverse self-locking can be achieved, that is, only the worm 230 can drive the worm gear 200, and the worm 230 cannot be driven by the worm gear 200, so that the rotating drum 120 cannot rotate by itself, so that it is more stable after clamping the crystal oscillator, and a driving component that drives the two driving rods 220 to rotate in the same direction at the same time is arranged on the top of the base 100;

[0033] Above the clamping assembly is provided with a mounting frame 300 at the top of the base 100. On the bottom wall of the top of the mounting frame 300 is provided a longitudinal linear motor 310. The output seat of the linear motor 310 moves longitudinally and a transverse cross plate 320 is provided at the bottom. At the bottom of the cross plate 320 is provided a transverse linear motor 330. The output seat of the linear motor 330 moves transversely and a vertical electric lifting rod 340 is provided at the bottom. At the bottom end of the electric lifting rod 340 is provided a detection needle 350 for detecting the crystal oscillator. The linear motor 310 drives the cross plate 320 and the detection needle 350 to move in the front and back directions, and the linear motor 330 drives the detection needle 350 to move in the left and right directions. The electric lifting rod 340 is used to adjust the height of the detection needle 350.

[0034] Further, the clamping assembly includes a transverse threaded column 130 screwed through the inside of the rotating cylinder 120. At one end close to each other of the two threaded columns 130 are provided symmetric mounting brackets 140. The mounting brackets 140 are in a "C" shape. Vertically through the top of the mounting bracket 140 is screwed a vertical screw rod 150. At the bottom of the screw rod 150 is provided a clamping plate 160. At the inner bottom of the mounting bracket 140 and at the bottom of the clamping plate 160 are provided buffer pads. The surface of the buffer pads is provided with anti-slip lines. By rotating the threaded column 130, the distance between the two mounting brackets 140 can be adjusted to facilitate fixing crystal oscillators of different sizes. Place the two sides of the crystal oscillator to be detected at the inner bottom between the two mounting brackets 140, and then rotate the screw rod 150 to adjust the height of the clamping plate 160 so that the clamping plate 160 presses down to fix the two sides of the top of the crystal oscillator.

[0035] Further, the driving assembly includes two fixing plates 240 provided on the top of the base 100 and behind the mounting frame 300. Between the two fixing plates 240 is rotatably provided a transverse rotating rod 250. The rear ends of the two driving rods 220 are behind the mounting frame 300 and are provided with bevel gears 270. On the rod body of the rotating rod 250 is provided a bevel gear 260 meshing with the bevel gear 270. When multi-sided detection of the crystal oscillator is required, rotate the rotating rod 250. The two driving rods 220 are simultaneously driven to rotate through the bevel gear 260 and the bevel gear 270, and then the rotating cylinder 120 is rotated through the worm 230 and the worm gear 200 to realize the synchronous rotation of the two mounting brackets 140. And because the worm 230 and the worm gear 200 can be reversely self-locked, that is, only the worm 230 can drive the worm gear 200, and the worm gear 200 cannot drive the worm 230, the rotating cylinder 120 cannot rotate by itself, so that it is more stable after clamping the crystal oscillator.

[0036] Furthermore, a fixing block 360 is fixedly provided on the bottom wall of the top of the mounting frame 300 at the front and rear ends of the cross plate 320, and two longitudinal guide rods 370 are provided on the side walls of the four fixing blocks 360. The rod bodies of the two guide rods 370 slide through the side walls of the cross plate 320 respectively. When the cross plate 320 moves in the front and rear directions, the cross plate 320 slides along the rod bodies of the guide rods 370, thereby improving the displacement stability of the cross plate 320.

[0037] During specific use, the distance between the two mounting frames 140 can be adjusted by rotating the threaded column 130, which is convenient for fixing crystal oscillators of different sizes. The two sides of the crystal oscillator to be tested are placed at the inner bottom between the two mounting frames 140, and then the screw 150 is rotated to adjust the height of the clamping plate 160 so that the clamping plate 160 presses down and fixes the tops of both sides of the crystal oscillator.

[0038] The horizontal plate 320 and the detection needle 350 can be driven to move in the front-to-back direction by the linear motor 1 310, and the detection needle 350 can be driven to move in the left-to-right direction by the linear motor 2 330, and the electric lifting rod 340 is used to adjust the height of the detection needle 350, so that the detection needle 350 can detect the crystal oscillator below it;

[0039] When multi-faceted detection of the crystal oscillator is required, the detection needle 350 is reset first, and then the rotating rod 250 is rotated, and the two driving rods 220 are driven to rotate simultaneously through the bevel gear 1 260 and the bevel gear 2 270, and then the rotating drum 120 is rotated through the worm 230 and the worm wheel 200, so that the two mounting frames 140 rotate synchronously. In addition, since the worm 230 and the worm wheel 200 can be reversely self-locked, that is, only the worm 230 can drive the worm wheel 200, and the worm wheel 200 cannot drive the worm 230, the rotating drum 120 cannot rotate by itself, and is thus more stable after clamping the crystal oscillator.

[0040] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
