[0039] The present invention provides an ultrasonic transducer pressing tool 100, which is used to press two or more separated parts to be pressed, so that the two or more parts to be pressed are connected and fixed. Specifically, in the present invention, the structure of the ultrasonic transducer pressing tool 100 will be described mainly by taking the ultrasonic transducer pressing tool 100 used to press the shell structure of the ultrasonic transducer as an example.

[0040] The ultrasonic transducer includes a shell structure, which includes a cable clamp assembly, a front shell assembly, a middle shell assembly and a tail shell assembly connected in sequence, wherein the cable clamp assembly includes a clamp tube and a cable structure, the front shell assembly includes a front shell, a plurality of first annular parts arranged in the front shell from back to front along the axial direction of the front shell, and a first kit arranged at the front end of the front shell, the middle shell assembly includes a middle shell, a plurality of second kits arranged in the middle shell from back to front along the axial direction of the middle shell, and a third kit arranged at the front end of the middle shell, the tail shell assembly includes a first tail shell, a second annular part sleeved in the tail shell, and a second tail shell connected to the tail shell, since the sizes and shapes of the first annular part, the first kit, the second kit, the third kit, and the second annular part may be inconsistent, different pressing parts are required for crimping during pressing. The ultrasonic transducer pressing tool 100 provided by the present invention can press the cable clamp assembly, the front shell assembly, the middle shell assembly and the tail shell assembly respectively, and then press the connections between the components.

[0041] Specifically, see Figures 1 to 4 In this embodiment, the ultrasonic transducer pressing tool 100 includes a base 1, an upper pressing assembly 2, and a lower pressing assembly 3; the upper pressing assembly 2 is arranged on the base 1, including an upper pressing piece that is movably arranged, and a pressing driving component 23 connected to the upper pressing piece, and the pressing driving component 23 can be adjusted to drive the upper pressing piece to move along the up and down direction of the base 1; the lower pressing assembly 3 is arranged on the base 1, including a lower pressing piece, and the lower pressing piece and the upper pressing piece are connected. The upper pressing parts are arranged relatively to each other along the up-down direction of the machine base 1, and have a movable stroke approaching and moving away from the lower pressing parts; wherein the upper pressing parts and the lower pressing parts are both detachably arranged on the machine base 1, at least one upper pressing part is provided, and at least one lower pressing part is also provided, one upper pressing part can be respectively pressed together with one or more of the multiple lower pressing parts, and one lower pressing part can be respectively pressed together with one or more of the multiple upper pressing parts.

[0042] In this embodiment, when pressing, the pieces to be pressed are stacked together in sequence and then placed on the lower pressing piece, and the upper pressing piece is driven to move in the direction of the lower pressing piece, so that the upper pressing piece and the lower pressing piece are pressed together on the pieces to be pressed, so that the two separable pieces to be pressed are pressed together; moreover, the movement of the upper pressing piece can be driven to move by the pressing driving component 23, so that the movement of the upper pressing piece is easier to control and will not be limited by the operating force of the operator, so that the pressing operation is more convenient, thereby achieving good pressing. The product rate is higher; moreover, at least one of the upper pressing piece and the lower pressing piece can be provided, so that different upper pressing pieces can be crimped with different lower pressing pieces correspondingly, so as to meet the pressing requirements of pressing pieces of different sizes or shapes. For example, the cable clamp assembly, the front shell assembly, the middle shell assembly and the tail shell assembly can be pressed, so that the ultrasonic transducer pressing tool 100 has a wider range of uses and can meet the pressing requirements of various components of the same workpiece, so that the pressing operation steps can be reduced and the operation is simpler, thereby effectively improving the processing efficiency.

[0043] As for the base 1, the specific shape and structure of the base 1 are not limited, as long as the upper pressing assembly 2 and the lower pressing assembly 3 can be installed thereon. Figures 1 to 4 As shown in the figure, the machine base 1 includes a top plate 12 and a bottom plate 11 which are arranged at a relative interval along the up and down directions, and a guide column 13 connected between the top plate 12 and the bottom plate 11, the upper pressing part and the lower pressing part are arranged in the interval area between the top plate 12 and the bottom plate 11, the upper pressing part can be connected to the top plate 12, and the lower pressing part is arranged on the bottom plate 11, so that a gap is formed between the upper pressing part and the lower pressing part, so as to facilitate the movement of the upper pressing part to be in a pressing state close to the lower pressing part, and in a waiting state away from the lower pressing part.

[0044] Specifically, combined Figures 1 to 4As shown, the upper pressing assembly 2 also includes a moving plate 25 and an upper mounting seat 26, wherein the moving plate 25 is slidably sleeved on the guide column 13 in the up-down direction; the upper mounting seat 26 is arranged on the moving plate 25; the pressing driving component 23 includes an adjusting nut 231 and an adjusting screw rod 232 screwed with the adjusting nut 231, the adjusting nut 231 is connected to the upper mounting seat 26, the adjusting screw rod 232 is extended in the up-down direction of the machine base 1, and is connected to the top plate 12; the upper pressing member is arranged on the moving plate 25, and the adjusting nut 231 is connected to the upper mounting seat 26, and ... The upper mounting seat 26 is arranged on the upper side of the movable plate 25, and the upper pressing piece is arranged on the lower side of the movable plate 25. The adjusting screw 232 is rotated by the external force, driving the adjusting nut 231 to move along the adjusting screw 232, driving the movable plate 25 and the upper pressing piece to move together along the up and down direction of the machine base 1. The upper pressing piece is driven by the matching screw nut, so that the upper pressing piece has higher precision when moving, thereby having higher pressing precision, and effectively controlling the pressing stroke to avoid damage to parts due to impact, and the pressing operation is safer.

[0045] Moreover, an adjustment handle 233 is provided at the upper end of the adjusting screw rod 232. The adjusting handle 233 is arranged in a ring shape. The adjusting screw rod 232 can be adjusted to rotate by rotating the adjusting handle 233, which is more labor-saving and convenient.

[0046] Preferably, if Figure 1 As shown in , the upper pressing part includes a first upper pressing column 21 and a second upper pressing column 22 which are detachably connected. The first upper pressing column 21 is connected to the movable plate 25. Specifically, the first upper pressing column 21 is connected to the movable plate 25 by screws; the second upper pressing column 22 is connected to the first upper pressing column 21, and at least part of it can protrude downward from the first upper pressing column 21 along the machine base 1. When the length of the workpiece to be pressed is small, the moving stroke of the first pressing part is larger. At this time, two upper pressing parts can be provided, that is, the second upper pressing column 22 is installed on the first upper pressing column 21, so that the length of the upper pressing part is longer, so that the moving stroke can be shorter and the pressing efficiency is higher; when the length of the workpiece to be pressed is relatively large, only one upper pressing part is required for pressing. The setting method of the upper pressing part is more flexible, so it can be suitable for pressing different workpieces to be pressed.

[0047] Further preferably, the first upper pressing column 21 and the second upper pressing column 22 are both extended in the up-down direction of the machine base 1, and the outer diameter of the second upper pressing column 22 is smaller than the outer diameter of the first upper pressing column 21. When the inner diameter of the workpiece to be pressed is small, the workpiece to be pressed cannot be pressed when the area of ​​the pressing hole of the upper pressing part is large. Therefore, the outer diameter of the first upper pressing column 21 and the outer diameter of the second upper pressing column 22 are set differently, so that workpieces to be pressed with different diameters can be pressed to ensure a better pressing effect. For example, when the ultrasonic transducer is pressing the cable structure into the inner side of the clamp tube, since the diameter of the cable structure is relatively small and smaller than the inner diameter of the first upper pressing column 21, the second upper pressing column 22 needs to be installed on the first upper pressing column 21, and then the cable structure is crimped through the second upper pressing column 22 with a smaller diameter. Moreover, a first avoidance hole is provided on the peripheral side wall of the second upper pressing column 22, through which the cable of the cable structure can pass through to avoid crushing the cable. When the front shell assembly is pressed, since the inner diameter of the front shell, the inner diameters of the multiple first annular parts and the first set are relatively large, and the outer diameter of the second upper pressing column 22 is relatively small and cannot act on the various components, at this time, the first upper pressing column 21 can be used for pressing to ensure that the various components can be evenly stressed and to ensure a better pressing effect.

[0048] Among them, combined Figure 1 , Figure 5 and Figure 6 As shown, the first upper pressing column 21 is hollow and has an open bottom. When pressing and discarding, the bottom end wall of the first upper pressing column 21 can be used to press the workpiece to be pressed, thereby pressing. Alternatively, a step portion is provided on the bottom end wall of the first upper pressing column 21, and the step portion is used to press the workpiece to be pressed. The second upper pressing column 22 is sleeved on the inner side of the first upper pressing column 21; the ultrasonic transducer pressing tool 100 also includes a connecting pin 24. A through hole is provided on the side wall of the first upper pressing column 21. The connecting pin 24 is inserted into the through hole and abuts against the outer peripheral side wall of the second upper pressing column 22. The second upper pressing column 22 is fixed to the first upper pressing column 21 through the connecting pin 24, and disassembly and assembly are relatively convenient.

[0049] Moreover, if Figure 6As shown in , the second upper pressing column 22 has an abutting surface 221 abutting against the connecting pin 24. The abutting surface 221 is arranged in a plane, and the end of the connecting pin 24 abutting against the abutting surface 221 is arranged in a spherical shape to ensure better pressing force. In addition, in the direction from top to bottom along the base 1, the abutting surface 221 is arranged to extend and tilt in a direction gradually approaching the center of the second upper pressing column 22 to form a local recessed area to prevent possible operation during pressing. Moreover, a step portion is formed between the inclined abutting surface 221 and the main body of the second upper pressing column 22 to limit the upper pressing part to prevent excessive pressing and damage to the cable clamp.

[0050] The lower pressing assembly 3 is used to place the workpiece to be pressed and cooperate with the upper pressing assembly 2 to form a pressing clamping force. Specifically, the lower pressing assembly 3 also includes a support seat 34 provided on the bottom plate 11. There are multiple lower pressing parts, and the multiple lower pressing parts can be connected and fixed to the support seat 34 respectively. By replacing different lower pressing parts, different types of workpieces to be pressed can be placed.

[0051] Preferably, combined Figure 1 and Figure 3 As shown, the plurality of lower pressing parts include a first lower pressing column 31 and a second lower pressing column 32, wherein the first lower pressing column 31 and the second lower pressing column 32 are both hollow, and the inner sides of the first lower pressing column 31 and the second lower pressing column 32 are both provided with a step portion, through which the workpiece to be pressed is limited on the first lower pressing column 31 or the second lower pressing column 32. Moreover, the length of the first lower pressing column 31 is consistent with the length of the second lower pressing column 32, and the inner diameter of the first lower pressing column 31 and the inner diameter of the second lower pressing column 32 are set differently, and the first lower pressing column 31 and the second lower pressing column 32 are used to allow the workpieces to be pressed with different outer diameters to be clamped therein, so that the ultrasonic transducer pressing tool 100 can press parts of different sizes.

[0052] More preferably, if Figure 2 As shown in , the plurality of lower pressing parts further include a third lower pressing column 33, wherein the length of the third lower pressing column 33 is greater than the length of the first lower pressing column 31 and the length of the second lower pressing column 32. When the length of the workpiece to be pressed is shorter, the third lower pressing column 33 can be installed on the support seat 34, so that the distance between the third lower pressing column 33 and the upper pressing part is smaller, thereby ensuring that the moving stroke of the upper pressing part is shorter and the pressing efficiency is higher. According to the height of the workpiece to be pressed, pressing parts of different heights are configured so that the pressing stroke of the upper pressing part is basically the same each time, reducing the idling distance of the rotating screw, thereby reducing the operation time.

[0053] There may be multiple third lower pressing columns 33, wherein the inner diameter of one of the third lower pressing columns 33 may be the same as the inner diameter of the first lower pressing column 31, or the inner diameter of another third lower pressing column 33 may be the same as the inner diameter of the second lower pressing column 32, or the inner diameters of the multiple third lower pressing columns 33 may be different. Reasonable settings may be made according to pressing requirements so that fewer pressing parts can be pressed while more parts to be pressed can be pressed.

[0054] The first lower pressing column 31 , the second lower pressing column 32 and the support seat 34 may all be provided with corresponding second avoiding holes, and the second avoiding holes may be used for allowing cables of the cable structure to pass through, so as to better protect the cables.

[0055] Since the outer diameter of the tail end of the tail housing is small and the length is long, a lower pressing piece with a shorter length is required for support and positioning. Figure 4 As shown in the figure, the multiple lower pressing parts also include a lower pressing ring 35, and the lower pressing ring 35 includes two symmetrically arranged pressing half rings. Since the length of the lower pressing ring 35 is relatively small, the lower pressing ring 35 is arranged as two pressing half rings, which makes it easier to place and fix the lower pressing ring 35 on the support seat 34 and also easier to take out the lower pressing ring 35.

[0056] The ultrasonic transducer pressing tool 100 provided by the utility model can be used to assemble various components of the shell structure of the same ultrasonic transducer, and can also be used to assemble shells of different ultrasonic transducers. It has a wider range of uses, greatly reduces the pressing operation steps, and effectively reduces the difficulty of the pressing operation, which can ensure a better pressing effect.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the specification and drawings of the present invention, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
