Description

Technical Field

[0001] The utility model relates to a spherical transducer gluing and assembling technology, in particular to a spherical transducer gluing spring clamp. Background Art

[0002] The spherical transducer is made of ceramic balls, bakelite pillars and flanges connected and glued together. During the gluing process, the ceramic balls, bakelite pillars and flanges need to be positioned and clamped to ensure that the transducer is in a coaxial state and cannot be displaced. The external pressure during gluing must be consistent to ensure that the products of the same batch are highly uniform, so that the product parameters remain relatively consistent and the product appearance can also ensure a certain degree of beauty.

[0003] The existing spiral clamps do not have this function. The transducer that is initially clamped by the spiral clamp, once it enters the oven for curing, will have a certain gap between the various parts of the transducer due to the thinning of the colloid, and the spiral clamp cannot continuously output the same pressure to the outside of the transducer, so the ceramic ball and the flange will be slightly offset, resulting in misalignment. The final transducer has general quality control and uneven appearance. The transducers produced in the same batch have uneven overall heights due to uneven force, and the consistency deviation of indicator parameters seriously affects the reliability of the product.

[0004] Moreover, the existing fixtures are complicated to install, difficult to operate, and have poor versatility, which do not meet the requirements of large-scale production and greatly reduce work efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a spherical transducer gluing spring clamp, which is used for gluing and assembling the spherical transducer, so that the yield rate of the spherical transducer is greatly improved, and includes a pull head, a pull rod, an upper plate, a pressure plate, a pillar, a spring, a lower plate, and a pin. The lower plate is the reference of the spring clamp, and one end of the pillar is arranged on the lower plate. At the same time, the pillar is vertically assembled with the lower plate through a threaded structure, and the pillar passes through the optical port feature on the pressure plate, and the pressure plate is arranged at the optical axis part in the middle of the pillar, which is a movable structural component with a high degree of directional freedom;

[0006] The other end of the pillar is arranged in the positioning hole of the upper plate. At the same time, the pillar is vertically assembled with the upper plate through a nut. At the same time, a positioning hole is provided at the center of the upper plate. After the pull rod passes through the positioning hole, it is fastened and assembled between the external threaded end face and the threaded hole provided in the center of the pressure plate.

[0007] In one embodiment of the utility model, a spring is provided on a characteristic section between the upper plate and the pressure plate of the assembled pillar, and the spring is coaxially assembled with the pillar.

[0008] In one embodiment of the utility model, a pull head is provided at the other end of the pull rod, and the two are assembled and connected via a threaded structure.

[0009] In one embodiment of the utility model, a hollow characteristic structure is provided on the pull rod shaft, and a pin is provided in the hollow characteristic structure.

[0010] The above technical solution of the utility model has the following advantages over the prior art: the spring clamp described in the utility model is an overall upper and lower structure, and is assembled with stainless steel. Stainless steel has high hardness, good pressure resistance, is not easy to deform at high and low temperatures, has a smooth surface, is not easy to wear, is corrosion-resistant, and is easy to clean. After long-term storage, the structure of the entire clamp can still maintain good consistency, which is convenient for long-term continued use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1 As shown, this embodiment provides a spherical transducer gluing spring clamp, which is used for gluing and assembling the spherical transducer, so that the yield rate of the spherical transducer is greatly improved, including a pull head 1, a pull rod 2, an upper plate 3, a pressure plate 4, a pillar 5, a spring 6, a lower plate 7, and a pin 8. The lower plate 7 is a reference of the spring clamp, and one end of the pillar 5 is arranged on the lower plate 7. At the same time, the pillar 5 is vertically assembled with the lower plate 7 through a threaded structure, and the pillar 5 passes through the optical port feature on the pressure plate 4, and the pressure plate 4 is arranged at the optical axis part in the middle of the pillar 5, which is a movable structural component with a high degree of directional freedom;

[0016] The other end of the support 5 is arranged in the positioning hole of the upper plate 3. At the same time, the support 5 is vertically assembled with the upper plate 3 through a nut. At the same time, a positioning hole is provided at the center of the upper plate 3. After the pull rod 2 passes through the positioning hole, it is fastened and assembled between the external threaded end face and the threaded hole provided in the center of the pressure plate 4.

[0017] Specifically, first install the two pillars 5 into the lower plate 7 and tighten them with a wrench, insert the pressure plate 4 into the two pillars 5, then put the two 1.2*22*200 springs 6 into the pillars 5 on both sides, put the upper plate 3 into the pillars 5 on both sides, tighten them with M10 nuts, insert the pull rod 2 from the middle hole of the upper plate 3, tighten the threaded hole between the pull rod 2 and the pressure plate 4 with a wrench, and finally screw the pull head 1 into the upper end of the pull rod 2.

[0020] A hollow characteristic structure is provided on the axis of the pull rod 2, and a pin 8 is provided inside the hollow characteristic structure.

[0021] Specifically, the spring clamp of this embodiment only needs to pull up the pull rod 2 of the clamp from the top until it reaches the required position, and then insert the pin 8, so that the whole clamp is in a ready state. Put the glued spherical transducer with the PTFE ring and the stainless steel base into the middle position of the clamp, pull out the pin 8 on the top, and let the pressure plate 4 slowly press the transducer.
