The utility model relates to the technical field of loudspeaker production, in particular to a voice coil positioning mechanism of a loudspeaker voice diaphragm assembly, which comprises a voice diaphragm seat and a voice coil seat, the voice diaphragm seat and the voice coil seat are connected through a support column, a groove is formed in the voice diaphragm seat, and an output shaft of a first cylinder penetrates through the bottom of the groove; a positioning column is arranged on the voice coil seat, and the top of the positioning column is driven by a second cylinder to lift on the voice coil seat; a voice diaphragm conveying belt and a voice coil conveying belt for feeding materials to the voice diaphragm base and the voice coil base are arranged between the voice diaphragm base and the voice coil base, a first containing groove and a first penetrating hole are formed in the voice diaphragm conveying belt at intervals, and a strip-shaped penetrating hole matched with the outer diameter of an output shaft of the first air cylinder is formed between the first containing groove and the first penetrating hole. The voice coil conveying belt is provided with a second placing groove and a second through hole. A rotating disc on the voice diaphragm base is used for bearing the assembled voice diaphragm assembly, mounting grooves are formed in the rotating disc in a circumferential array mode, third penetrating holes are formed in the bottoms of the mounting grooves, and a correcting mechanism is installed on the rotating disc. According to the invention, the bonding efficiency and bonding quality of the voice diaphragm and the voice coil are improved.

The utility model discloses a kind of adjustable stroke type battery box welding support device, it includes support rod, support head, inner hexagonal bolt and cushion block;The both ends of support rod are provided with threaded hole, support head is equipped with two groups, two groups of support head are respectively connected by its screw rod segment threaded matching support rod threaded hole;Threaded hole is opened in the rod body of support rod, and inner hexagonal bolt is spun into from the threaded hole of support rod and is connected cushion block after passing downwards.This new type of support rod and support head are all used screw joint, when two end support head is spun out and the support surface of battery box is pasted tightly, support stroke can be adjusted and fixed, and cannot occur because of the problem of support not or unable to place caused by too long or too short range distance.Support device height and length two directions stroke adjustable and flexible dismounting, so wood hammer is not needed to be used to knock, guarantee the placement precision of support device, and then make device both ends even stress.

The utility model relates to an eggplant seedling transplanter which comprises a movable rack, a clamping jaw structure and a ground breaking structure, the clamping jaw structure and the ground breaking structure are fixed on the movable rack, and a seedling picking structure, a seedling lifting structure and a tray telescopic structure are further arranged on the movable rack; the seedling picking structure comprises a lead screw lifting assembly and a first-stage inserting disc, and the lead screw lifting assembly is fixed to the bottom of the movable rack and is in driving connection with the first-stage inserting disc; the seedling lifting structure comprises a chain wheel lifting assembly and a second-stage inserting disc, the chain wheel lifting assembly is fixed to one side of the movable rack and is in driving connection with the second-stage inserting disc, and the second-stage inserting disc and the first-stage inserting disc are oppositely distributed; the tray telescopic structure comprises a lead screw horizontal telescopic assembly, an arc-shaped guide rail and a tray, the lead screw horizontal telescopic assembly is fixed to the top of the movable rack and rotatably connected with the tray, the tray is slidably connected with the arc-shaped guide rail, and the tray is located under the clamping jaw structure. Compared with the prior art, the device has the advantages of high automation degree, high transplanting efficiency, low cost and the like.

The invention relates to the technical field of milling equipment, and discloses a milling machine for machining mechanical equipment parts, which comprises a base, a milling mechanism is mounted at the top of the base, a moving table is arranged at the top of the base, and a moving seat is arranged at the top of the moving table. Pressing mechanisms are fixedly arranged at the positions, close to the middle portions, of the front face and the back face of the movable table correspondingly, and a clamping mechanism is arranged at the top of the movable base. The corresponding positions of the feeding station, the discharging station, the milling station and the cleaning station are switched through movement of the movable base, dynamic switching of the temporary clamping state of the clamping mechanism is matched, the adjusting mechanism drives the movable base to move to the cleaning station and drives the movable base to turn over, a cavity opening faces downwards while a workpiece moves, and the workpiece can be conveniently cleaned. And the recovered cooling liquid is matched to clean the inner cavity of the workpiece and the placement surface of the moving seat, so that the cleaning effect on the cavity of the workpiece is improved while the convenience of workpiece machining operation is ensured, the cleanliness of the placement surface of the moving seat is ensured, and the milling quality of the workpiece is ensured.
