Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, and specifically relates to tooling fixtures for loudspeaker production. Background Technology

[0002] In loudspeaker manufacturing, tooling fixtures are one of the core pieces of equipment ensuring product accuracy, stability, and production efficiency. The core components of a loudspeaker, such as the frame, diaphragm, and magnetic circuit system, typically have asymmetrical or complex geometries, and require extremely high assembly precision. Traditional fixtures mostly employ fixed positioning structures, requiring operators to precisely place the workpiece at the geometric center or a preset position of the fixture; otherwise, uneven clamping force distribution, workpiece misalignment, or even damage may occur.

[0003] For example, during the clamping process of the basin frame, if the workpiece is not aligned with the center of the clamping assembly, the clamping mechanism may cause the basin frame to deform or fail to position due to multi-directional thrust when applying force. Utility Model Content

[0004] This utility model addresses the problems of the prior art by providing a tooling fixture for loudspeaker production. The specific technical solution is as follows:

[0005] Tooling fixtures for loudspeaker manufacturing include:

[0006] Support base, used to support the entire fixture and place the workpiece;

[0007] A medium supply channel is used to supply gaseous or liquid media to the clamping assembly;

[0008] Multiple sets of clamping assemblies are circumferentially disposed on the support base, and the multiple sets of clamping assemblies form a clamping area for accommodating the workpiece; each set of clamping assemblies includes:

[0009] The fixing base is fixedly installed on the end face of the support base;

[0010] A clamping element is slidably connected to one end of the fixed base facing the clamping area;

[0011] The medium channel connects the fixed base and the medium supply channel, and is used to transport the medium into the fixed base and drive the clamping member to move toward the workpiece.

[0012] The output end of the clamping member is provided with a pressure feedback component, and the medium channel is provided with a control valve that is communicatively connected to the pressure feedback component.

[0013] When the clamping component contacts the workpiece, the pressure feedback component is pressed and sends a pressure signal. If the pressure signal reaches a preset threshold, the control valve closes to cut off the medium delivery and maintain the current pressure, so that multiple sets of clamping components work together to form a surrounding clamping force field on the workpiece.

[0014] As a further technical solution of this utility model, the preset pressure threshold is less than the thrust required to push the workpiece to slide.

[0015] As a further technical solution of this utility model, the output end of the clamping member is detachably connected to a clamping head adapted to the shape of the workpiece, and an elastic contact portion is provided on the end face of the clamping head facing the workpiece, and the pressure feedback component is disposed on the surface of the elastic contact portion.

[0016] As a further technical solution of this utility model, the detachable structure of the clamping member and the clamping head includes:

[0017] A slot is provided at the end of the clamping member;

[0018] An insert block is connected to the connecting end of the clamping head and mates with the slot;

[0019] And fastening screws, screwed to the side of the clamping member and pressing against the insert.

[0020] As a further technical solution of this utility model, multiple sets of clamping components are evenly distributed along the circumference of the clamping area, and the clamping force is adaptively adjusted by the medium pressure to achieve stable clamping of the eccentrically placed workpiece.

[0021] The beneficial effects of this utility model are as follows:

[0022] (1) In this application, an open clamping area is formed by circumferentially distributed clamping components, which eliminates the traditional clamping fixture's mandatory requirement for workpiece center positioning. Operators only need to place the workpiece into the clamping area to complete the clamping, which significantly shortens the clamping time and is especially suitable for rapid loading and unloading scenarios on assembly lines.

[0023] (2) In this application, the clamping components are linked by the medium pressure to form a surrounding clamping force field. Even if the workpiece is placed off-center, each clamping group can still adaptively adjust the clamping force through the pressure feedback mechanism to ensure that the workpiece maintains a high-precision fixed position during welding, assembly and other processes.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Figure 1 A schematic diagram of the overall structure of the tooling fixture used in loudspeaker production is shown; Figure 1 The speaker manufacturing fixture includes a support base 100, a medium supply channel 200, and a clamping assembly 300. The support base 100 supports the entire fixture and places the workpiece. The medium supply channel 200 supplies medium to the clamping assembly 300. Multiple sets of clamping assemblies 300 are arranged circumferentially, forming a clamping area 400. In this application, the workpiece only needs to be placed at any point in the clamping area 400, and the multiple sets of clamping assemblies 300 can cooperate to form a stable clamping mechanism for the workpiece. Fixed clamping eliminates the traditional requirement for workpiece center positioning. Operators only need to place the workpiece into the clamping area 400 to complete the clamping, shortening the workpiece clamping time. It is especially suitable for rapid loading and unloading in assembly line operations. Multiple clamping components 300, evenly distributed around the circumference, work together to form a surrounding clamping force field. Even if the workpiece is placed off-center, each clamping group can still adaptively adjust the clamping force through the medium pressure, ensuring that the workpiece maintains a high-precision fixed position during welding, assembly and other processes. The product defect rate can be reduced by more than 40%.

[0031] It should be noted that the medium supplied by the medium supply channel 200 is either gas or liquid.

[0032] Figure 2 A schematic diagram of the clamping assembly 300 is shown. Figure 2In the clamping assembly 300, a fixed base 310, a clamping member 320, and a media channel 330 are included. The fixed base 310 is fixedly mounted on the end face of the support base 100. The clamping member 320 is slidably connected to one end of the fixed base 310 facing the clamping area 400. The media channel 330 is connected between the fixed base 310 and the media supply channel 200. In actual use, the media is delivered to the fixed base 310 through the media channel 330 and drives the clamping member 320 to move toward the workpiece to clamp it. A pressure feedback assembly 342 is provided at the output end of the clamping member 320. A control valve 331 is provided on the media channel 330. The elastic contact part 341 and the control valve 331 communicate with each other. The communication connection means that when the clamping member 320 is driven by the medium to move towards the workpiece, as the output end of the clamping member 320 contacts the workpiece, the pressure feedback component 342 located between the output end of the clamping member 320 and the workpiece is pressurized and sends a pressure signal. When the pressure feedback of the pressure signal reaches the preset threshold, the control valve 331 closes to cut off the medium delivery and maintain the current pressure. At this time, the clamping component 300 of this group completes its work, but the clamping members 320 in other clamping components 300 continue to move towards the workpiece to form an eccentric clamping until all clamping components 300 have completed the workpiece. At this time, multiple clamping components 300 can form an eccentric clamping of the workpiece, and the clamping force in the circumferential direction is uniform.

[0033] It should be noted that the pressure feedback component 342 is a thin-film pressure sensor.

[0034] It should be noted that the preset pressure threshold must be less than the thrust required to slide the workpiece; for example, if the thrust required to slide the workpiece is 100N, then the preset pressure threshold is between 0-100N, but not including 100N; the specific setting can be customized according to the size and model of the workpiece, and this application does not impose too many restrictions.

[0035] Figure 3 A schematic diagram of the clamping head 340 is shown; Figure 3In this design, the clamping head 340 is detachably connected to the output end of the clamping member 320 to correspond to the shape of the workpiece. An elastic contact portion 341 is provided on the end face of the clamping head 340 facing the workpiece, and a pressure feedback component 342 is disposed on the surface of the elastic contact portion 341. By using the clamping head 340, different clamping heads 340 can be replaced for different workpieces, thereby forming a matching clamping surface. Furthermore, the design of the elastic contact portion 341 avoids rigid contact with the workpiece, protecting the contact surface from damage. The detachable structure of the clamping head 340 and the clamping member 320 includes a slot. 321, fastening screw 322 and insert 343, slot 321 is formed at the end of clamping member 320 and matches insert 343, insert 343 is connected to the connecting end of clamping head 340 and inserted into slot 321, fastening screw 322 is screwed to the side of clamping member 320 and presses against insert 343; in actual use, clamping head 340 and clamping member 320 are connected and disconnected by inserting and pulling insert 343 and slot 321, and after connection, fastening screw 322 rotates inward to apply a lateral pressure to insert 343 to ensure stable connection.

[0036] The elastic contact part 341 can be a soft structure such as rubber or silicone.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
