[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figure 1-2 A terminal crimping machine for automobile wiring harness processing includes a frame 1; a hydraulic cylinder 2, mounted on the frame 1; a mounting base 3, fixed to the telescopic end of the hydraulic cylinder 2; a top die 4, detachably mounted on the mounting base 3; a bottom die 5, fixed to the frame 1 and arranged opposite the top die 4; a mounting groove 6, provided on the side of the mounting base 3, the shape of the top die 4 being adapted to the shape of the mounting groove 6; two guide grooves 7, both provided on the groove wall of the mounting groove 6; and two guide blocks 8, both fixed to the top die 4.

[0037] The terminal crimping machine also includes a fixing structure, which is arranged on the mounting base 3. The fixing structure includes: two fixing frames 91, both of which are fixed to the side surfaces of the mounting base 3 and are respectively located on both sides of the mounting groove 6; two clamping blocks 92, which are respectively slidably arranged on the two fixing frames 91, and the ends of the two clamping blocks 92 close to each other are provided with inclined surfaces. The fixing frame 91 has a U-shaped structure, and the side surfaces of the fixing frame 91 and the side surfaces of the clamping blocks 92 fit together; two tension springs 93, one end of which is connected to the mounting base 3, and the other end is respectively connected to the two clamping blocks 92. When installing the top mold 4, the staff directly aligns the two guide blocks 8 on the top mold 4 with the two guide grooves 7, and inserts the top mold 4 into the mounting groove 6, so that the two guide blocks 8 are respectively inserted into the two guide grooves 7. In this During the process, the two guide blocks 8 will squeeze the inclined surfaces of the two clamping blocks 92. When the inclined surfaces of the clamping blocks 92 are squeezed, the clamping blocks 92 will move. Therefore, the two clamping blocks 92 will move away from each other under the squeezing action of the two guide blocks 8. When the two guide blocks 8 are fully inserted into the two guide grooves 7, the two clamping blocks 92 will be reset under the action of the two tension springs 93 and block the two guide grooves 7. At this time, the two clamping blocks 92 jointly fix the top mold 4 to prevent the top mold 4 from escaping from the mounting groove 6. In addition, when the top mold 4 is inserted into the mounting groove 6, the side surfaces of the two guide blocks 8 are respectively fitted with the groove walls of the two guide grooves 7, and the two guide blocks 8 are respectively fitted with the two clamping blocks 92, which can ensure the stability of the top mold 4 in the mounting groove 6.

[0038] The terminal crimping machine also includes a control structure, which is arranged on the mounting base 3. The control structure includes: a rotating shaft 101, which is rotatably mounted on the top surface of the mounting base 3, and a knob is fixed to the top of the rotating shaft 101; a gear 102, which is fixedly sleeved on the rotating shaft 101; two racks 103, which are respectively located on both sides of the gear 102, and the two racks 103 are engaged with the gear 102; two connecting rods 104, one end of which is fixedly connected to the two racks 103, and the other end of which is fixedly connected to the two blocks 92.

[0039] The specific working principle of this utility model is as follows:

[0040] When the terminal crimping machine for automobile wiring harness processing proposed by the present invention is in use and it is necessary to disassemble and maintain the top mold 4, the staff first turns the knob. When the knob is turned, it can drive the rotating shaft 101 to rotate, and the gear 102 thereon will also rotate accordingly. When the gear 102 rotates, it can drive the two racks 103 to move and move away from each other. When the two racks 103 move, they can drive the two clamping blocks 92 to move through the two connecting rods 104, so that the two clamping blocks 92 move away from each other. When the two clamping blocks 92 move away from each other, they no longer block the two guide grooves 7. Without the restriction of the two clamping blocks 92, the top mold 4 can fall off from the mounting groove 6. The staff can directly pull out the top mold 4 to achieve rapid disassembly of the top mold 4.

[0041] When the top mold 4 is installed, the staff directly aligns the two guide blocks 8 on the top mold 4 with the two guide grooves 7, and inserts the top mold 4 into the installation groove 6 so that the two guide blocks 8 are respectively inserted into the two guide grooves 7. In this process, the two guide blocks 8 will squeeze the inclined surfaces of the two clamping blocks 92. When the inclined surfaces of the clamping blocks 92 are squeezed, the clamping blocks 92 will move. Therefore, the two clamping blocks 92 will move away from each other under the squeezing action of the two guide blocks 8. When the two guide blocks 8 are fully inserted into the two guide grooves 7, the two clamping blocks 92 will be reset under the action of the two tension springs 93 and block the two guide grooves 7. At this time, the two clamping blocks 92 jointly fix the top mold 4 to prevent the top mold 4 from detaching from the installation groove 6. In addition, when the top mold 4 is inserted into the installation groove 6, the side surfaces of the two guide blocks 8 are respectively in contact with the groove walls of the two guide grooves 7, and the two guide blocks 8 are respectively in contact with the two clamping blocks 92, so that the stability of the top mold 4 in the installation groove 6 can be ensured.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
