Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1, the present embodiment provides a terminal crimping machine which is convenient to use, and includes a frame 1, a workbench 2 disposed on the frame 1, a mold 3 mounted on the workbench 2 for placing a terminal (in the prior art, the mold 3 is typically detachably mounted on the workbench 2 by screws or other components, so as to conveniently replace the corresponding mold 3 according to the size of the terminal), and a crimping component 5 driven by a driving component mounted on the frame 1 for crimping the terminal. The driving member may employ a cylinder 4.

The crimping component 5 comprises a connecting seat 51 fixedly mounted at the output end of the driving member, a disc-shaped cutter disc 52 is rotatably connected to the connecting seat 51, and a plurality of cutter dies 53 distributed along the circumferential direction of the cutter disc 52 are mounted on the circumferential surface of the cutter disc 52, preferably 6 cutter dies can be adopted, and certainly not limited to the number;

in order to adapt to production, a terminal crimping machine generally designs several commonly used dies 3 in a matching way, and each die 3 corresponds to one cutting die 53 for crimping a terminal; the connecting seat 51 is provided with the locking piece 6 for locking the cutter disc 52, so that the common cutting dies 53 can be installed on the cutter disc 52 at one time for convenience, and therefore, when a new die 3 is replaced in the later period, only the cutter disc 52 needs to be rotated, and the cutting die 53 corresponding to the die 3 on the cutter disc 52 is rotated to be right above the die 3 of the processing station.

In this embodiment, as shown in fig. 2 and 3, an annular mounting groove 521 is formed on the circumferential surface of the cutter disc 52 and is coaxial with the cutter disc 52; the cutter disc 52 is detachably mounted in the mounting groove 521; the cutting die 53 comprises a cutter handle 531 with a square cross section and a cutter head 532 arranged at the end part of the cutter handle 531; it should be noted that, in all the cutting dies 53 mounted on the cutter head 52, the tool bits 532 of the cutting dies 53 correspond to the specific die 3, and the tool shanks 531 are the same.

The groove walls on the two sides of the mounting groove 521 are provided with embedding grooves 522 for embedding the knife handle 531, and the embedding grooves 522 can play a role in positioning, so that the mounting position of the knife handle 531 can be conveniently found; the knife handle 531 is connected with the mounting groove 521 through a locking component.

The locking assembly comprises a bolt 71 and a nut 72, and a first through hole 523 horizontally penetrating through the caulking groove 522 is formed in the cutter disc 52; a second through hole 5311 is formed in the knife handle 531 at a position corresponding to the first through hole 523; the bolt 71 is threaded to the nut 72 after passing through the first through hole 523 and the second through hole 5311.

Through the above arrangement, the installation and the disassembly of the cutting die 53 can be facilitated.

In order to conveniently position the selected cutting die 53 to the processing station, the connecting seat 51 is provided with a locking piece 6 for locking the cutter disc 52, the locking piece 6 comprises a screw 61 and a hand wheel 62 fixedly connected to one end of the screw 61, and the hand wheel 62 is provided with two wing plates 63; the connecting seat 51 is in an inverted U-shaped structure, and the end part of a piston rod of the air cylinder 4 is fixedly connected to the upper end of the connecting seat 51; the center of the cutter disc 52 is rotationally connected to the middle of the connecting seat 51 through a rotating shaft 525; the screw rod 61 is horizontally screwed on the side wall of one side of the connecting seat 51; the side wall of the cutter disc 52 close to the screw 61 is provided with a plurality of positioning holes 524 distributed along the circumferential direction of the cutter disc 52 and allowing the inner end of the screw 61 to be inserted, wherein the positioning holes 524 are in one-to-one correspondence with the cutting dies 53, and since the number of the cutting dies 53 used in the present embodiment is 6 and the included angle between two adjacent cutting dies 53 is 60 degrees, the positioning holes 524 are also provided with 6 corresponding to each other, and the included angle between two adjacent positioning holes 524 is also 60 degrees.

The implementation principle is as follows: when a new mold 3 is replaced on the table 2, the screw 61 is rotated first to separate the inner end of the screw 61 from the positioning hole 524; then, the cutter disc 52 is rotated to enable the cutting die 53 matched with the die 3 on the cutter disc 52 to rotate to a processing station (right above the die 3), at the moment, the positioning hole 524 on the cutter disc 52 corresponds to the position of the screw 61, the screw 61 is rotated to enable the inner end of the screw 61 to be inserted into the positioning hole 524, so that the screw 61 has a limiting effect on the cutter disc 52, the cutter disc 52 cannot rotate, and at the moment, the crimping operation can be carried out; the air cylinder 4 drives the whole pressing plate to press down through the connecting seat 51, so that the cutter die 53 on the cutter disc 52 can press and connect the terminal placed in the die 3.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
