Description

Technical Field

[0001] This application relates to the field of clamping and positioning devices, for example, to a crystal oscillator clamping and positioning device. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] Crystal oscillators, as key components in electronic devices, are widely used in communications, computers, and consumer electronics. Precise positioning is crucial during crystal oscillator production and testing to ensure accurate testing and excitation. However, existing crystal oscillator positioning devices suffer from the following problems in practical applications: Crystals have dimensional tolerances during production, and existing clamping devices, typically with fixed structures, cannot accommodate these tolerances. When clamping multiple crystals simultaneously, ordinary clamping devices can only effectively clamp the largest crystal, failing to provide sufficient clamping force for smaller crystals. This uneven clamping force causes positioning deviations in some crystals during testing and excitation, affecting the accuracy of test results and the excitation effect. Existing positioning devices are mostly made of ordinary metal or plastic materials, which have poor wear resistance. Over prolonged use, the contact parts of the positioning device are prone to wear due to frequent friction, leading to a gradual decrease in positioning accuracy. This wear not only exacerbates crystal positioning deviations but may also cause poor contact, further affecting the stability of testing and excitation. Summary of the Invention

[0004] This application provides a crystal oscillator clamping and positioning device. The bottom and first side of the crystal oscillator are supported and positioned by the bottom side of the clamping groove and the first sidewall, respectively. Combined with the positioning groove at the front end of the straightening plate, adjacent and opposite surfaces of the crystal oscillator are positioned, achieving precise clamping and positioning of the three surfaces of the crystal oscillator. Driven by a linear drive mechanism, the straightening plate moves along a direction forming an angle S with the first sidewall, ensuring that the positioning groove first engages with the two sides of the crystal oscillator. After the first side of the crystal oscillator is tightly fitted against the first sidewall, the straightening plate stops moving, completing the clamping and positioning. This avoids the positioning deviation problems caused by wear or workpiece tolerances in traditional positioning devices.

[0017] In some embodiments, the linear drive mechanism further includes: a first slide rail;

[0018] The first slide rail is mounted on the fixed frame and slides in conjunction with the mounting plate, limiting the movement of the mounting plate in a direction that forms an angle S with the first side wall.

[0024] The vertical rod is connected to the mounting plate at the top and slidably set in the limiting groove at the bottom, sliding along the extension direction of the limiting groove.

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0052] The workpieces include crystal oscillators and similar shaped products, such as rectangular products or products with rectangular protrusions.

[0053] Combination Figure 1-10 As shown, this embodiment of the present disclosure provides a crystal oscillator clamping and positioning device, including: a clamping groove 12, a straightening plate 11, and a linear drive mechanism;

[0054] The clamping groove 12 includes a bottom side surface 121 and a first side wall 122. The bottom side surface 121 supports and positions the bottom of the crystal oscillator, and the first side wall 122 supports and positions the first side surface of the crystal oscillator. The bottom side surface 121 and the first side wall 122 are the inner sides of the clamping groove 12. The bottom side surface 121 is a plane, and the first side wall 122 is a plane perpendicular to the bottom side surface 121.

[0055] The corrector 11 slides in conjunction with the clamping groove 12, and has a positioning groove 13 at its front end. The positioning groove 13 positions the adjacent and opposite surfaces of the first side. The positioning groove 13 includes two mutually perpendicular second sidewalls 132 and third sidewalls 131, which intersect. A corner relief groove is provided at the intersection to provide space for the crystal oscillator's apex corner. The second sidewalls 132 and third sidewalls 131 position the adjacent and opposite surfaces of the first side.

[0056] A linear drive mechanism, connected to the corrector plate 11, drives the corrector plate 11 to move in a direction forming an angle S with the first sidewall 122. When the positioning groove 13 approaches the first sidewall 122, it cooperates with the corrector plate 11 to clamp and position the three surfaces of the crystal oscillator. When the groove moves away from the first sidewall 122, the clamping and positioning are released. The value range of the angle S is: 0° < S < 90°.

[0057] The crystal oscillator clamping and positioning device provided in this embodiment supports and positions the bottom and first side of the crystal oscillator via the bottom side 121 of the clamping groove 12 and the first sidewall 122, respectively. Combined with the positioning groove 13 at the front end of the straightening plate 11, adjacent and opposite surfaces of the crystal oscillator are positioned, achieving precise clamping and positioning of the three surfaces of the crystal oscillator. Driven by a linear drive mechanism, the straightening plate 11 moves along a direction forming an angle S with the first sidewall 122, ensuring that the positioning groove 13 initially engages with the two sides of the crystal oscillator. After the first side of the crystal oscillator is tightly fitted against the first sidewall 122, the straightening plate 11 stops moving, completing the clamping and positioning process. This avoids the positioning deviation problem caused by wear in traditional positioning devices. The clamping groove 12 and the straightening plate 11 can be made of high-hardness, wear-resistant materials (such as ceramics or special alloys), significantly improving the wear resistance of the device and extending its service life.

[0058] In some embodiments, the bottom side 121 of the clamping groove 12 is provided with a blow-suction hole 123, which is connected to a blow-suction device. When the blow-suction hole 123 is in the suction state, the provided negative pressure causes the crystal oscillator to be adsorbed at the bottom of the clamping groove 12, greatly increasing the friction between the crystal oscillator and the bottom side 121, preventing the corrector 11 from knocking the crystal oscillator away when it touches it. The blow-suction device is a negative pressure suction device.

[0059] In some embodiments, the included angle S ranges from 30° to 60°. The included angle S can be 30°, 45°, or 60°.

[0060] In some embodiments, the linear drive mechanism includes: a mounting plate 2, an excitation tray 1, an elastic element 14, a fixing frame 5, and an opening mechanism;

[0061] Mounting plate 2 is connected to the front end of the corrective piece 11; mounting plate 2 is a rectangular plate.

[0062] The excitation tray 1 has a first groove and a first slide 3 on the upper part. The first slide 3 is a rectangular slide 3. There are multiple first grooves and first slide 3. The first groove can accommodate and install the clamping groove 12. The first slide 3 is in sliding fit with the mounting plate 2.

[0063] The elastic element 14, with one end connected to the excitation tray 1 and the other end connected to the mounting plate 2, provides a force to move the straightening plate 11 toward the first sidewall 122; the elastic element 14 is a spring. Traditional clamping devices, due to their fixed structure, cannot adapt to dimensional tolerances between workpieces, typically only clamping the largest workpiece, while the remaining workpieces, being smaller, cannot be effectively clamped. This device solves this problem by providing clamping force through the elastic element 14. Each workpiece has a corresponding individual elastic element providing clamping force. The elastic element has a large stroke, enabling it to adapt to different workpiece tolerances, and is particularly suitable for scenarios where the workpiece's dimensional tolerance is within the range of 0–1 mm.

[0064] In some embodiments, the elastic element corresponds one-to-one with the mounting plate, and the mounting plate corresponds one-to-one with the straightening piece.

[0065] The fixing frame 5 is located below the excitation tray 1; the excitation tray is located on the fixing frame.

[0066] The opening mechanism, mounted on the fixed frame 5, provides a force that moves the corrective piece 11 away from the first sidewall 122.

[0067] In some embodiments, the opening mechanism includes a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0068] In some embodiments, the linear drive mechanism further includes: a first slide rail 16;

[0069] The first slide rail 16 is mounted on the fixed frame 5 and slides in conjunction with the mounting plate 2, limiting the movement of the mounting plate 2 in a direction forming an angle S with the first side wall 122. The first slide rail 16 is provided with a slider, which is connected to the mounting plate 2.

[0070] In some embodiments, the opening mechanism includes: a limiting plate 10, a cylinder 6, a second slide rail 4, a limiting groove 101, and a vertical rod 15; the cylinder 6 drives the opening of the corrective plate 11, and the elastic element 14 springs back to position the crystal oscillator.

[0071] Limiting plate 10 is positioned below excitation material tray 1;

[0072] Cylinder 6, mounted on fixed frame 5, drives limiting plate 10 to move in the X-axis direction;

[0073] The second slide rail 4 is mounted on the fixed frame 5 and slides in cooperation with the limiting plate 10 to limit the movement of the limiting plate 10 in the X-axis direction; the second slide rail 4 is provided with a slider, which is connected to the limiting plate 10.

[0074] A limiting groove 101 is provided on the upper part of the limiting plate 10, and its extension direction intersects with the movement direction of the mounting plate 2 as perpendicularly projected onto the limiting plate 10; the number and position of the limiting grooves 101 correspond one-to-one with the mounting plate 2. The limiting groove 101 is an elongated oval hole-shaped groove.

[0075] The vertical rod 15 is connected to the mounting plate 2 at its upper end and slidably disposed in the limiting groove 101 at its lower end, sliding along the extending direction of the limiting groove 101. The vertical rod 15 is cylindrical.

[0076] When the limiting plate 10 moves in the X-axis direction, the limiting groove 101 also moves synchronously. The sliding direction of the mounting plate 2 is different from the moving direction of the limiting plate 10. When the limiting plate 10 moves, it drives the vertical rod 15 to move. The vertical rod 15 moves in the sliding direction of the mounting plate 2 and slides in the limiting groove 101 at the same time.

[0077] In some embodiments, a crystal oscillator clamping and positioning device includes multiple sets of clamping slots and straightening plates, as well as corresponding linear drive mechanisms. For example, as shown in the figures, it has four sets of clamping slots, linear drive mechanisms, and straightening plates. However, there is only one set of excitation tray, opening mechanism, and fixing frame. The excitation tray is provided with a corresponding number and position of first grooves and first slides. The limiting plate is provided with a corresponding number of limiting slots that cooperate with the mounting plate. Each straightening plate has a separate mounting plate and elastic element for use. Therefore, the clamping force of each straightening plate is driven by a separate corresponding spring and is not affected by other springs, wear of the straightening plate, or workpiece tolerances.

[0078] In some embodiments, the crystal oscillator clamping and positioning device further includes: a needle 9, a retainer 7, and a quick-release connector 8;

[0079] Needle 9, the upper part of which is connected to the blow-suction hole 123;

[0080] The retainer 7 secures the needle 9 to the retainer 5.

[0081] The quick-release connector 8 is connected to the needle 9 at the top and to the blow-suction device at the bottom via a pipe.

[0082] In some embodiments, the lower part of the vertical rod 15 is connected to a bearing, which is disposed in and engages with a limiting groove. The bearing rolls within the limiting groove.

[0083] The foregoing description and accompanying drawings fully illustrate embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the order of operation may vary. Parts and features of some embodiments may be included or substituted for parts and features of other embodiments.
