Description

A terminal crimping machine

technical field

The utility model specifically relates to a terminal crimping machine.

Background technique

Terminal block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. At the same time, terminal crimping machines for terminal blocks have also developed rapidly. The existing terminal crimping machine includes a driving mechanism, two tooth plates, two fixed pieces, and is arranged on the jaws of the two tooth plates. However, due to the unreasonable structural design of the existing jaws, during processing, the jaws The processing is difficult, the yield rate is low, and the manufacturing cost is high, and the existing jaws are fixed on the dental plate by screws. When the jaws need to be replaced, the staff needs to remove multiple screws, so the terminal crimping machine has a clamp The defect that the port replacement is not convenient enough.

Contents of the invention

The purpose of the utility model is to overcome the defects of the prior art and provide a terminal crimping machine with simple structure, convenient jaw replacement and low production cost.

In order to achieve the above purpose, the utility model adopts a terminal crimping machine, which includes a driving mechanism and a pliers head linked with the driving mechanism. 1. The two jaws respectively arranged on the two tooth plates, the corresponding jaws on the tooth plates are provided with matching arc-shaped grooves, and the two ends of the arc-shaped grooves are each provided with a Semi-cylindrical bosses, matching grooves are provided on the jaws corresponding to the bosses, and the bosses are respectively snapped into the grooves to form a flexible connection between the tooth plate and the jaws , and the tooth plate is provided with a limit device for limiting the movement of the jaws. The limit device includes a sliding pin, a driving rod, and a spring. The sliding pin is arranged in a guide hole on the tooth plate, The spring is arranged in the guide hole, and the lower end of the spring is in contact with the upper end surface of the sliding pin, the lower end of the sliding pin is clamped in the clamping cavity on the jaw, and the driving rod passes through the sliding pin The mounting hole on the top is clamped in the through hole of the dental plate by the spring retaining ring, and the driving rod can drive the sliding pin to move up and down in the guide hole to realize the separation and connection of the sliding pin and the jaws.

In particular, the snap-in cavity is an arc-shaped slot or a circular blind hole, and the lower end of the sliding pin is snapped into the arc-shaped slot or the circular blind hole. By setting the snap-in cavity on the jaws as an arc-shaped slot or a circular blind hole, it is more convenient to process the arc-shaped slot and the round blind hole when processing the jaws, thereby improving the production efficiency of the jaws.

In particular, the drive mechanism is a cylinder or an electric mechanism.

The beneficial effect of the utility model is: the terminal crimping machine is provided with a semi-cylindrical boss and a limit device on the dental plate, and a groove matching the boss is arranged on the jaw, so that the jaw can be clamped On the boss, and the limit device can fix the jaws on the tooth plate, and the boss on the tooth plate is set in a semi-cylindrical shape, so that the processing of the tooth plate and jaws set by this structure is more convenient and the processing yield is high. High, saving production costs; when the jaw needs to be replaced, just move the lever on the limit device upward, the lever drives the sliding pin to move, and the sliding pin compresses the spring to move upward, so that the lower end of the sliding pin and the clamp The jaws are separated, that is, the jaws lose the restriction of the sliding pin, and the jaws can be disassembled from the dental plate; thus, the terminal crimping machine has the advantages of simple structure, convenient jaw replacement, and low production cost.

Detailed ways

As shown in Figures 1, 2, and 3, the embodiment of the utility model is a terminal crimping machine, which includes a driving mechanism 13 and a pliers head linked with the driving mechanism 13. Two tooth plates 14, two fixing pieces 15, and two jaws 16 respectively arranged on the two tooth plates 14. Corresponding jaws 16 on the dental plate 14 are provided with matching arc grooves 141, and both ends of the arc grooves 141 are respectively provided with a semi-cylindrical boss 142, the pliers Corresponding to each boss 142 place on the mouth 16 is all provided with the groove 161 that matches, and described each boss 142 is correspondingly clamped in each groove 161 respectively and forms the flexible connection of tooth plate 14 and jaw 16. And described dental plate 14 is provided with the limiting device 20 that is used to limit jaw 16 action, and described limiting device 20 all comprises sliding pin 21, driving lever 22, spring 23, and described sliding pin 21 is arranged on tooth. In the guide hole 143 on the plate 14, the spring 23 is arranged in the guide hole 143, and the lower end of the spring 23 is in contact with the upper end surface of the sliding pin 21, and the lower end of the sliding pin 21 is clamped on the jaw 16. In the clamping cavity 162 on the top, the clamping cavity is an arc-shaped slot or a circular blind hole, and the lower end of the sliding pin is clamped in the arc-shaped slot or the circular blind hole. By setting the snap-in cavity on the jaws as an arc-shaped slot or a circular blind hole, it is more convenient to process the arc-shaped slot and the round blind hole when processing the jaws, thereby improving the production efficiency of the jaws. The driving rod 22 passes through the mounting hole 211 on the upper part of the sliding pin 21 and is clamped in the through hole 144 on the dental plate 14 through the retaining ring 24, and the driving rod 22 can drive the sliding pin 21 in the guide hole. Movement up and down in 143 realizes the separation and connection of slide pin 21 and jaw 16. The driving mechanism is a cylinder or an electric mechanism. The terminal crimping machine is provided with a semi-cylindrical boss and a limiting device on the dental plate, and a groove matching the boss is provided on the jaw, so that the jaw can be clamped on the boss, and the limit The device can fix the jaws on the tooth plate, and the boss on the tooth plate is set in a semi-cylindrical shape, so that the tooth plate and jaws with this structure are more convenient to process, the processing yield is high, and the production cost is saved; when When the jaw needs to be replaced, just move the lever on the limit device upward, the lever drives the sliding pin to move, and the sliding pin compresses the spring to move upward, so that the lower end of the sliding pin is separated from the jaw, that is, the jaw is lost. The jaws can be disassembled from the dental plate due to the restriction of the sliding pin; thus, the terminal crimping machine has the advantages of simple structure, convenient jaw replacement, and low production cost.
