Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices, specifically relating to a grinding device for processing the housing of a power amplifier. Background Technology

[0002] Power amplifiers, as crucial modules for signal amplification and output in electronic devices, are widely used in broadcasting and communications, audio equipment, radar systems, and industrial automation control, among other fields. Their performance stability and heat dissipation capabilities have a decisive impact on the overall operation of the device. The power amplifier's housing not only provides support, protection, and structural integration but also undertakes important functions such as heat conduction and dissipation for core components, mechanical protection, and electromagnetic shielding. Therefore, the processing quality of the power amplifier housing, especially the smoothness and precision of its outer surface, requires extremely high standards. Typically, post-forming grinding is necessary to eliminate burrs, oxide layers, and machining textures, thereby improving overall assembly quality and performance.

[0003] However, in the existing technology, the grinding device for the power amplifier shell mostly adopts the manual loading and unloading method. Usually, the ground shell is manually removed from the processing station and replaced with a new unground shell. This operation is inefficient and affects the production speed.

This device can automatically transfer unprocessed amplifier housings to the processing position for automatic positioning, clamping, and grinding. After grinding, it can automatically unload the material. While the feeding and processing processes are in progress, the feeding guide groove, which has already released all the amplifier housings, can be loaded. The device has a high degree of automation, strong continuity of automatic feeding and processing actions, and effectively improves processing continuity and efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing the housing of a power amplifier, comprising a machine base, a roller mounting frame mounted on the top of the machine base, multiple equally spaced support rollers rotatably mounted on the inner side of the roller mounting frame, a first motor installed inside the roller mounting frame, a clamping device mounted on the top of the machine base, and an automatic feeding auxiliary device mounted on the top of the machine base.

Two sets of feeding guide grooves are connected to the outer side of the rotating bracket. A first electric telescopic rod is installed on the side of the feeding guide groove. The piston rod end of the first electric telescopic rod is connected to the bottom baffle. A discharge ramp runs through the top and bottom of the machine platform. A buffer baffle plate is provided at one end of the discharge ramp. A grinding device is provided on the top of the machine platform.

[0006] The beneficial effects of this utility model are as follows: This device is equipped with an automatic alternating feeding structure consisting of a third motor, a rotating bracket, and two feeding guide grooves.

After polishing, it can automatically unload the material. While the feeding and processing processes are in progress, the feeding guide grooves that have released all the amplifier shells can be loaded. The overall automation level is high, the automatic feeding and processing actions are highly continuous, and the processing continuity and efficiency are effectively improved.

The positioning device includes a second cylinder mounted on the bottom of the machine base via a bracket. The top of the piston rod of the second cylinder is connected to a positioning plate. A through groove is provided between the top and bottom of the machine base. The positioning plate is inserted into the through groove.

[0008] During the feeding process, the second cylinder at the bottom of the machine drives the positioning plate to pass through the lower through slot, which limits the amplifier housing pushed onto the support roller, preventing it from rolling out due to inertia and also serving a positioning function.

[0009] To secure the amplifier housing:

The piston rod end of the first cylinder is connected and fixed to the clamping plate.

[0011] After the amplifier housing is positioned on the support roller, the first cylinder drives the clamping plate to move toward the amplifier housing. The clamping operation is completed by the cooperation of the clamping plates on both sides to ensure that it does not shift during the grinding process.

[0012] To drive the amplifier housing to move into place before processing and to automatically unload it after processing:

[0013] As a further improvement to the above technical solution: the support rollers located near both ends and the middle of the roller mounting frame have one end connected to the output end of the first motor.

[0014] The beneficial effects of this improvement are as follows: the operation of the first motor can drive the support roller connected to its output end to rotate, thereby moving the amplifier housing located above the support roller, which is used to move the amplifier housing into place before processing and to automatically unload it after processing.

[0020] When polishing the top of the amplifier housing, the polishing motor is started to drive the polishing disc to rotate. The second electric telescopic rod, the first linear driver, and the second linear driver work together to drive the polishing motor to move and adjust in multiple directions in the Z, Y, and X directions, so that the polishing disc polishes the top of the amplifier housing according to the programmed path.

[0021] To limit the stacking of power amplifier housings in the feed chute:

[0022] As a further improvement to the above technical solution: a blocking frame is hinged to one side of the feed guide chute, and magnetic blocks are provided on one side of the blocking frame and one side of the feed guide chute.

A third motor 14 is installed inside the rotating shaft mounting base 13. A rotating bracket 15 is also rotatably installed on the inner side of the rotating shaft mounting base 13. The output end of the third motor 14 is connected to the rotating bracket 15. Two sets of feed guide grooves 16 are connected to the outer side of the rotating bracket 15. A first electric telescopic rod 19 is installed on the side of the feed guide groove 16. The piston rod end of the first electric telescopic rod 19 is connected to the bottom baffle 20. A discharge ramp 27 is provided between the top and bottom of the machine base 1. A buffer baffle plate 28 is provided at one end of the discharge ramp 27. A grinding device is provided on the top of the machine base 1.

[0033] This device is equipped with an automatic alternating feeding structure consisting of a third motor 14, a rotating bracket 15, and two feeding guides 16. It can automatically transfer unpolished amplifier housings to the processing position in sequence for automatic positioning, clamping, and polishing. After polishing, it can automatically unload the material. While the feeding and processing processes are in progress, the feeding guides 16, which have already released all amplifier housings, can be loaded. The overall automation level is high, and the continuity of automatic feeding and processing actions is strong, effectively improving the continuity and efficiency of processing.

[0034] A positioning device is installed at the bottom of the machine base 1. The positioning device includes a second cylinder 8 installed at the bottom of the machine base 1 via a bracket. The top of the piston rod of the second cylinder 8 is connected to the positioning plate 9. A through groove is provided between the top and bottom of the machine base 1. The positioning plate 9 is inserted into the through groove.

[0035] During the feeding process, the second cylinder 8 at the bottom of the machine base 1 drives the positioning plate 9 to pass through the lower through groove, which limits the amplifier housing pushed onto the support roller 3, preventing it from rolling out due to inertia and playing a positioning role.

[0036] The clamping device includes a fixed base 5 installed on the top of the machine base 1. A first cylinder 6 is installed on one side of the fixed base 5, and the piston rod end of the first cylinder 6 is connected and fixed to the clamping plate 7.

[0037] After the amplifier housing is positioned on the support roller 3, the first cylinder 6 drives the clamping plate 7 to move toward the amplifier housing. The clamping operation is completed by the cooperation of the clamping plates on both sides to ensure that it does not shift during the grinding process.

[0038] The support rollers 3, located near both ends and the middle of the roller mounting frame 2, have one end connected to the output end of the first motor 4.

[0039] The operation of the first motor 4 can drive the support roller 3 connected to its output end to rotate, thereby moving the amplifier housing located above the support roller 3, which is used to move the amplifier housing into place before processing and to automatically unload it after processing.

[0040] One end of the feeding base 10 is provided with an ejection port, and the top of the feeding base 10 is a feeding port.

[0041] The ejection port is used for the amplifier housing to exit from the feed base 10, and the feed port is used for the amplifier housing to enter the feed base 10 from the feed guide 16.

[0042] The grinding device includes a grinding device bracket 29 fixed to the top of the machine base 1. A second electric telescopic rod 21 is installed below the top of the grinding device bracket 29. A first linear driver 22 is installed at the bottom of the second electric telescopic rod 21.

A grinding motor 25 is installed inside the motor mounting compartment 24. The output end of the grinding motor 25 is connected to the grinding disc 26.

[0043] When polishing the top of the amplifier housing, the polishing motor 25 is started to drive the polishing disc 26 to rotate. The second electric telescopic rod 21, the first linear driver 22, and the second linear driver 23 work together to drive the polishing motor 25 to perform multi-directional movement adjustment in the Z, Y, and X directions, so that the polishing disc 26 polishes the top of the amplifier housing according to the programmed path.

[0044] A barrier frame 17 is hinged to one side of the feed guide 16, and magnetic blocks 18 are provided on one side of the barrier frame 17 and one side of the feed guide 16.

[0045] The feed guide 16 and the barrier frame 17 are magnetically fixed together by magnetic blocks 18, so that the barrier frame 17 can limit the power amplifier housing stacked in the feed guide 16 and prevent it from collapsing.

[0046] The working principle and usage process of this utility model: A control device is provided on the side of the machine base 1 for controlling this device. In use, multiple power amplifier housings to be ground are first stacked and placed into the feed guide 16. After feeding one feed guide 16 is completed, the barrier frame 17 can be closed. The barrier frame 17 and the feed guide 16 are magnetically fixed by magnetic blocks 18 to prevent the power amplifier housings from falling out. The bottom baffle 20 supports the stacked power amplifier housings. Then, the third motor 14 is controlled to drive the rotating bracket 15 to rotate, moving the fed feed guide 16 above the feed base 10 and aligning it with the feed inlet at the top of the feed base 10. Then, the other feed guide 16 can be processed. The feeding process involves positioning one of the two feeding guide troughs 16 in the feeding position and the other in the loading position. This allows for simultaneous feeding of one feeding guide trough 16 and loading of the other, ensuring continuous material supply and effectively improving processing continuity and efficiency. For the feeding guide trough 16 in the feeding position, the first electric telescopic rod 19 drives the bottom baffle 20 to move horizontally and retract into the space on the bottom side of the feeding guide trough 16. Under the influence of gravity, the lowest power amplifier housing falls into the feeding base 10 through the feeding port. Subsequently, the servo cylinder 11 drives the push plate 12 to push the housing along a horizontal path through the push port to the top of the support roller 3. Then, the push plate 12 retracts, and the next amplifier housing is then... The amplifier housing falls to the inner bottom of the feeding base 10, awaiting the next feeding. During this process, the second cylinder 8, located at the bottom of the machine base 1, drives the positioning plate 9 through the lower through slot to limit the amplifier housing pushed onto the support roller 3, preventing it from rolling out due to inertia and providing a positioning function. At the same time, the first motor 4 runs, helping the amplifier housing, which has moved onto the support roller 3, to contact the positioning plate 9. After the amplifier housing is positioned on the support roller 3, the first cylinder 6 drives the clamping plate 7 to move towards the amplifier housing. The clamping operation is completed by the cooperation of the clamping plates on both sides, ensuring that it does not shift during the grinding process. Then, the grinding motor 25 is started to drive the grinding disc 26 to rotate, and the second electric telescopic rod 21 and the first linear driver 2... 2. The second linear actuator 23 works in conjunction with the grinding motor 25 to move and adjust in multiple directions in the Z, Y, and X directions, so that the grinding disc 26 grinds the top of the amplifier housing according to the programmed path. After the processing is completed, the first cylinder 6 drives the clamping plate 7 to leave the amplifier housing, and at the same time the second cylinder 8 drives the positioning plate 9 to move downward, releasing the limitation on the amplifier housing. Then, the first motor 4 is controlled to run and drive the support roller 3 connected to its output end to rotate, which drives the amplifier housing to move towards the unloading ramp 27, so that the amplifier housing is transferred to the unloading ramp 27 and slides down the unloading ramp 27, and is limited by the buffer barrier plate 28 to prevent impact, waiting to be picked up. At this time, the grinding process of a single power amplifier housing is completed.In summary, this device is equipped with an automatic alternating feeding structure consisting of a third motor 14, a rotating bracket 15, and two feeding guides 16. It can automatically transfer unpolished amplifier housings to the processing position in sequence for automatic positioning, clamping, and polishing. After polishing, it can automatically unload the material. While the feeding and processing processes are in progress, the feeding guides 16, which have already released all amplifier housings, can be loaded. The overall automation level is high, and the continuity of automatic feeding and processing actions is strong, effectively improving the continuity and efficiency of processing.
