In this embodiment, the sleeve joint part 102a and the hollow barrel part 102b are made into an integral whole by injection molding process. When the transducer shell is assembled on the transducer 101, only the first shell 102 and the second shell 103 need to be respectively mounted on the transducer 101, and the first shell 102 and the second shell 103 are assembled and connected with each other, so that the assembly of the transducer shell on the transducer 101 can be completed.

[0059] Referring to Figures 6 to 16 The assembly equipment of the transducer assembly is shown, which specifically includes a rotating seat 1, a pushing seat 2, a mounting seat 4, and an elastic member 3. The rotating seat 1 is rotatably arranged about a first center line X1, and a connecting structure 13 is arranged on the rotating seat 1 to fixedly connect the transducer 101. When the transducer 101 is connected to the rotating seat 1, the transducer 101 extends in a first direction, and the axis line of the transducer 101 is co-linearly extended with the first center line X1. The pushing seat 2 is slidably arranged on the rotating seat 1 in the first direction, and when the transducer 101 is fixedly connected to the rotating seat 1, the pushing seat 2 can abut against the end face of the first shell 102 in the first direction. The mounting seat 4 has a mounting part for positioning and mounting the second shell 103, and the mounting seat 4 is rotatably arranged about a second center line X2, which is co-linearly extended with the first center line X1 and extends in the first direction. The mounting seat 4 and the pushing seat 2 are spaced apart from each other in the first direction. The elastic member 3 is arranged between the pushing seat 2 and the rotating seat 1 to provide the required force for the movement of the pushing seat 2 in the first direction towards the mounting seat 4.

[0060] Therefore, when the transducer assembly 10 is assembled, the first shell 102 is first mounted on the transducer 101, the pushing seat 2 is driven to move away from the mounting seat 4, so that the elastic member 3 is converted into an energy storage state, the transducer 101 is fixedly connected to the rotating seat 1 through the connecting structure 13, and the second shell 103 is mounted on the mounting part of the mounting seat 4, as shown in Figure 13 , Figure 14 Then, the mounting seat 4 with the second shell 103 is driven to move towards the rotating seat 1, so that the second shell 103 is sleeved on the rear part of the transducer 101 and abuts against the hollow barrel part 102b of the first shell 102 in the first direction, as shown in Figure 15 ,Figure 16 As shown in the drawings, the outer edge of the hollow cylinder part 102b is expanded by using a tool such as a wrench 9, and is sleeved to the front part of the second shell 103; after the rear part of the hollow cylinder part 102b is sleeved to the front part of the second shell 103, a ring of sealant is coated on the outer side of the circumference of the front part of the second shell 103; finally, the rotating seat 1 is driven to rotate around the first center line X1, and the sealant is continuously coated, so that the sealant is coated on the 360° of the outer side of the circumference of the front part of the second shell 103; then the pusher seat 2 is released, and the pusher seat 2 is pushed on the front end surface of the first shell 102 under the action of the elastic member 3; at this time, the transducer 101, the first shell 102 and the second shell 103 are rotated around the first center line X1, and the pusher seat 2 pushes the first shell 102 to move towards the second shell 103 under the lubrication of the sealant and the pushing action of the elastic member 3, so that the hollow cylinder part 102b is sleeved on the outer side of the circumference of the second shell 103 more and more, and is combined and fixed as a whole by the sealant, thereby realizing the assembly of the transducer shell on the transducer 101.

[0061] Specifically, referring to the drawings, the rotating seat 1 comprises a connecting disc 11, and the assembly device further comprises a driving mechanism 6, an output shaft 61 of the driving mechanism 6 is coaxially fixedly connected with the connecting disc 11; here, the driving mechanism 6 is a motor, and a fixed disc 62 is coaxially and fixedly arranged on the output shaft 61 of the motor, the size and shape of the fixed disc 62 are matched with the size and shape of the connecting disc 11, and the fixed disc 62 is used for coaxially and fixedly connecting with the connecting disc 11; in this way, when the motor works, the output shaft 61 of the motor can drive the rotating seat 1 to rotate around the first center line X1.

[0062] The rotating seat 1 further comprises a guide seat 12, the guide seat 12 is coaxial and fixed on one side of the connecting disc 11, and the pusher seat 2 is sleeved on the guide seat 12 in a sliding fit; the elastic member 3 is a spring, the spring is sleeved on the guide seat 12, and the spring abuts between the connecting disc 11 and the pusher seat 2, so as to drive the pusher seat 2 to move away from the connecting disc 11 by a required force.

[0063] Specifically, referring to the drawings, Figures 9 to 12 As shown in the drawings, the guide seat 12 is provided with a guide sliding groove 121 extending in the first direction; the pusher seat 2 is provided with a guide protrusion 24, and the guide sliding groove 121 and the guide protrusion 24 are both provided with two groups or more than two groups of protrusions or grooves arranged at intervals in the circumferential direction, and all the guide sliding grooves 121 and the guide protrusions 24 are in one-to-one sliding fit. Here, the guide sliding groove 121 and the guide protrusion 24 are provided with two groups of corresponding matching protrusions or grooves, and the two groups are distributed at an interval of 180° in the circumferential direction.

[0064] The guide seat 12 is also provided with a limiting groove 122 and a mounting groove 123. The length extension direction of the limiting groove 122 and the guide slide 121 is perpendicular to each other, and the length extension direction of the mounting groove 123 and the guide slide 121 is parallel to each other. The mounting groove 123 extends through the end of the guide seat 12 along the length direction. The guide protrusion 24 can slide and cooperate with the mounting groove 123 and the limiting groove 122 and can enter the guide slide 121 through the mounting groove 123 and the limiting groove 122.

[0065] In this embodiment, see Figure 12 As shown, a connecting shaft portion 125 is fixedly provided at one end of the guide seat 12 for coaxial fixed connection with the connecting disc 11; the other end of the guide seat 12 has an annular protrusion 124 for limiting the guide protrusion 24 at one end of the guide groove 121; the main body portion of the guide seat 12 located between the connecting shaft portion 125 and the annular protrusion 124 has a diameter larger than the diameter of the connecting shaft portion 125 and smaller than the diameter of the annular protrusion 124; the mounting groove 123, the limiting groove 122 and the guide groove 121 are sequentially arranged on the main body portion.

[0066] The push seat 2 includes a cylindrical sleeve 21 with a hollow cavity, and a push block 22 fixedly disposed at one end of the sleeve 21 and located in the sleeve 21. A limit ring 25 is provided at the other end of the sleeve 21. Two sets of guide protrusions 24 are disposed on the inner peripheral wall of the limit ring 25. When the push seat 2 is sleeved on the guide seat 12, the sleeve 21 is coaxially and slidably sleeved on the guide seat 12. Specifically, the annular protrusion 124 slides through the inner cavity of the sleeve 21 and is limited at both ends by the limit ring 25 and the push block 22.

[0067] When installing the pusher seat 2 onto the rotating seat 1, the pusher seat 2 can first be fitted onto the guide seat 12, so that the two sets of guide protrusions 24 correspond to and cooperate with the two sets of mounting grooves 123 respectively. Then, the two sets of guide protrusions 24 slide along the two sets of mounting grooves 123 to the corresponding limiting grooves 122. The pusher seat 2 is rotated at a certain angle, so that the two sets of guide protrusions 24 slide to the other end of the limiting grooves 122. Then, the pusher seat 2 is driven to slide relative to the guide seat 12, so that the two sets of guide protrusions 24 slide in the two sets of guide grooves 121 respectively.

[0068] The connecting structure 13 is disposed on the guide seat 12. After the transducer 10 is fixedly connected to the rotating seat 1 through the connecting structure 13, it can rotate synchronously with the rotating seat 1. Specifically, the connecting structure 13 is a threaded hole opened on the guide seat 12. The threaded hole is coaxially arranged with the guide seat 12, that is, the center line of the threaded hole extends collinearly with the first center line X1. A connecting screw 101c is also fixedly disposed on the front part 101a of the amplitude rod of the transducer 101. When the connecting screw 101c is threadedly connected to the aforementioned threaded hole, the transducer 101 can be fixedly connected to the rotating seat 1.

[0069] The pushing seat 2 has an avoiding structure which can be passed through by the front part 101a of the amplitude lever to be connected with the connecting structure 13, and here the avoiding structure is specifically an avoiding hole 23 which is opened on the pushing block 22 and axially penetrates through, and the front part of the front part 101a of the amplitude lever can axially pass through the avoiding hole 23 and be connected with the guide seat 12. Specifically, the avoiding hole 23 can be set as an inner hexagonal through hole, so as to be fixedly connected with the end of the sleeve 21 by a matching tool.

[0070] Referring to Figures 6 to 16 As shown, the mounting seat 4 includes a bottom plate (not shown in the figure), and a ring-shaped baffle 41 extending from the bottom plate to one side, and a mounting cavity is formed between the ring-shaped baffle 41 and the bottom plate, and the opening of the mounting cavity is towards the rotating seat 1, and the second shell 103 can be matched and clamped in the mounting cavity. Wherein, the ring-shaped baffle 41 is provided with a plurality of open grooves 42 which are circumferentially spaced, and the opening of each open groove 42 penetrates through the end of the ring-shaped baffle 41 away from the bottom plate, which makes the second shell 103 be clamped in the mounting seat 4 after entering the mounting cavity and can rotate with the mounting seat 4. At the same time, the open groove 42 can also provide the lead wire reserved on the transducer 10 to pass in, so as to be connected to the conductive plate subsequently.

[0071] The assembly device also includes a moving seat 5 which is translationally arranged on the machine base 8 along the first direction, and the mounting seat 4 is rotationally arranged on the moving seat 5 around the second center line X2, and specifically, a connecting shaft can be fixedly connected on the bottom plate of the mounting seat 4 and rotationally installed on the moving seat 5 through a rolling bearing.

[0072] The machine base 8 is also provided with a locking assembly 7 for locking the moving seat 5 on the machine base 8. Referring to the figures, in the embodiment, the machine base 8 is fixedly provided with a linear guide rail 81 which extends along the first direction, and the moving seat 5 is slidingly matched with the linear guide rail 81, and the locking assembly 7 includes a locking piece 71 and an operating piece 72 connected with the locking piece 71, and the length extension direction of the locking piece 71 is perpendicular to the first direction, and the locking piece 71 has a locking end 71a which can abut against the machine base 8, and the locking piece 71 is threadedly connected on the moving seat 5 to make the locking end 71a move close to or away from the machine base 8. Specifically, the operating piece 72 is specifically a handle which is rotationally connected on the upper end of the locking piece 71, and the locking end 71a is the lower end of the locking piece 71, and the locking piece 71 can be rotated by driving the operating piece 72 to rotate, so as to make it ascend or descend along the vertical direction relative to the moving seat 5, so that when the locking piece 71 moves downward to make the locking end 71a abut against the linear guide rail 81, the moving seat 5 is locked and cannot slide along the first direction; and when the locking piece 71 moves upward to make the locking end 71a abut against the linear guide rail 81, the moving seat 5 can move along the first direction.

[0073] The assembly equipment used in this embodiment is for example... Figures 1 to 5 When assembling the transducer assembly 10, first, refer to Figures 6 to 8 As shown, the pusher seat 2 is driven to move towards the connecting plate 11 of the rotating seat 1 against the force of the elastic element 3. When the guide protrusion 24 in the pusher seat 2 slides along the guide groove 121 to the limiting groove 122, the pusher seat 2 is rotated so that the guide protrusion 24 is locked in the limiting groove 122. At this time, the pusher seat 2 cannot slide relative to the rotating seat 1. This not only makes the elastic element 3 switch to an energy storage state, but also allows the threaded hole on the guide seat 12, which serves as the connecting structure 13, to expose the self-avoiding hole 23.

[0074] Next, the first housing 102 is fitted onto the transducer 101 from front to back. Then, the front part 101a of the amplitude transformer of the transducer 101 is inserted into the clearance hole 23 of the pusher seat 2, and threadedly connected to the threaded hole on the guide seat 12 by connecting screws 101c. This ensures that the transducer 101 is coaxially and fixedly connected to the rotating seat 1, with the first housing 102 located on one side of the pusher seat 2, allowing the pusher seat 2 to axially push against the end of the first housing 102. Simultaneously, one end of the second housing 103 is snapped into the mounting cavity of the mounting base 4, exposing the portion of the second housing 103 that needs to be covered by the hollow cylindrical portion 102b of the first housing 102, i.e., the exposed front adhesive portion 103a, forming a... Figure 13 , Figure 14 As shown in the structure, at this time, the first housing 102 has not yet been assembled to the corresponding position on the transducer 101, and the first housing 102 and the second housing 103 have a gap in the first direction.

[0075] Subsequently, the movable seat 5 is driven to slide along the linear guide rail 81, causing the movable seat 5, along with the mounting seat 4 and the second housing 103, to move towards the first housing 102 until the rear part 101b of the amplitude rod of the transducer 101 is inserted into the inner cavity of the second housing 102, so that the rear part 101b of the amplitude rod and the positioning part 103b on the second housing 102 are correspondingly engaged, realizing the installation of the transducer 101 and the second housing 103. At this time, the movable seat 5 is locked onto the base 8 by the locking assembly 7, so that the position of the mounting seat 4 in the first direction is fixed, forming as shown in the figure. Figure 15 , Figure 16 The structure shown.

[0076] Next, we can use methods such as Figure 17The wrench 9 shown is used to assist the engagement of the first shell 102 and the second shell 103. Specifically, the wrench 9 includes a grip portion 91 and a head portion 92. An operator holds the grip portion 91 and uses the head portion 92 to pry the outer periphery of the hollow cylindrical portion 102b of the first shell 102, so that the mouth portion expands and is sleeved onto the second shell 103. After the hollow cylindrical portion 102b is wrapped around the second shell 103 in one circumferential direction, at least the front end of the glue joint portion 103a is covered by the hollow cylindrical portion 102b.

[0077] Subsequently, the motor of the driving mechanism 6 operates, the output shaft 61 rotates with the rotating seat 1, and the transducer 101 and the first shell 102 and the second shell 103 are driven to rotate synchronously, so that the glue joint portion 103a is coated with a ring of sealant on the outer periphery. Then, the rotating pusher seat 2 is rotated, so that the guide protrusion 24 is returned to the guide sliding groove 121. Under the action of the elastic member 3, the pusher seat 2 pushes the first shell 102 to move towards the second shell 103, so that the hollow cylindrical portion 102b of the first shell 102 abuts against the second shell 103 in the axial direction. Under the elastic force of the elastic member 3 and the lubricating effect of the sealant, the first shell 102 moves relative to the second shell 103, so that the hollow cylindrical portion 102b of the first shell 102 is wrapped more and more onto the outer periphery of the glue joint portion 103a of the second shell 103, and the two are filled with sealant. After the sealant dries, the first shell 102 and the second shell 103 are connected in a mutually fixed and sealed manner, and the assembly of the transducer shell on the transducer 101 is completed.

[0078] In summary, the assembly equipment of the embodiment assists the installation of the first shell 102 and the second shell 103 of the transducer assembly 10 on the transducer 101 and the assembly of the first shell 102 and the second shell 103 relative to each other through the cooperation of the rotating seat 1, the pusher seat 2, the mounting seat 4, and the elastic member 3, which brings convenience to the overall assembly of the transducer assembly 10 and improves the assembly efficiency and quality. In the assembly process, the hollow cylindrical portion 102b does not need to be expanded as a whole, and the lubricating effect of the sealant is also ingeniously used, so that the hollow cylindrical portion 102b is more easily sleeved onto the second shell 103, and the assembly of the transducer shell is more convenient.
