[0031] Embodiment, referring to Figures 1 - 2, which is an embodiment of the present utility model, proposes a positioning device for a housing crimping head, including a base 9, a positioning plate 2, and a support block 4. The positioning plate 2 is arranged above the base 9 and is used for positioning the housing 10; the support block 4 is arranged above the base 9 and on one side of the positioning plate 2 and is used for supporting the housing 10; it further includes an elastic member 7 and a limiting block 5. The elastic member 7 is arranged between the positioning plate 2 and the base 9; limiting blocks 5 are arranged at both ends of the base 9, and the positioning plate 2 forms a vertical sliding fit with the limiting blocks 5 for the housing 10 to descend and contact the support block 4.

[0032] Furthermore, it further includes a limit pin 6. A chute 14 is provided on the limiting block 5, and limit pins 6 are arranged at both ends of the positioning plate 2. The limit pins 6 form a sliding fit with the chute 14. As Figure 1 and Figure 2 shown, the positioning plate 2 is located between the left and right limiting blocks 5. Limit pins 6 are arranged on both the left and right sides of the positioning plate 2, and chutes 14 are provided on both the left and right limiting blocks 5. The left and right limit pins 6 respectively form a vertical sliding fit with the corresponding chutes 14. The cooperation between the limit pins 6 and the chutes 14 plays a role of guiding and limiting, which can prevent the positioning plate 2 from shifting in the front-back direction during the up and down movement, and the stability is better.

[0033] Furthermore, it further includes a guide pin 8. The guide pin 8 is arranged at the bottom of the positioning plate 2, and a guide groove 15 is provided on the upper end surface of the base 9. The guide pin 8 forms a sliding fit with the guide groove 15. As Figure 1 shown, during the lifting and lowering process of the positioning plate 2, the left and right guide pins 8 both lift and lower synchronously along the guide groove 15, which can play a role of guiding and limiting, making the positioning plate 2 more stable during the up and down movement.

[0034] Furthermore, the elastic member 7 is sleeved around the guide pin 8. As Figure 1 shown, the guide pin 8 can play a role of guiding and limiting for the elastic member 7, and prevent the elastic member 7 from bending during the telescopic process, resulting in the deviation of the positioning plate 2.

[0035] Furthermore, the connection between the limiting block 5 and the base 9 is detachable, which is convenient for the disassembly, installation and maintenance of the positioning plate 2, and also convenient for the disassembly and installation of the limiting block 5. It further includes a locking bolt 16. The screw rod of the locking bolt 16 passes through the limiting block 5 and is threadedly connected to the base 9. As Figure 1 and Figure 2 shown, each limiting block 5 is locked to the base 9 through two locking bolts 16. The connection is firm and reliable, the disassembly and installation are convenient, fast, time-saving and labor-saving.

[0036] Further, it further includes a locking screw 12 and a locking nut 13. The locking screw 12 is arranged on the positioning plate 2, and a through hole for passing through the locking screw 12 is formed on the housing 10; the locking nut 13 is threadedly connected to the locking screw 12 and is used to press the housing 10 against one side of the positioning plate 2. As Figure 1 and Figure 2 shown, the housing 10 is sleeved on the lifting screw 12, and the cooperation between the locking nut 13 and the locking screw 12 can clamp the housing 10 between the locking nut 14 and the positioning plate 2. The connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort.

[0037] Further, it further includes a positioning nut 17. The positioning nut 17 is threadedly connected to the locking screw 12, and the positioning plate 2 is clamped between the two positioning nuts 17. As Figure 2 shown, the two positioning nuts 17 lock the locking screw 12 and the positioning plate 2 together. The structure is simple, the connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort. By changing the positions of the two positioning nuts 17, the lengths of the locking screw 12 on both sides of the positioning plate 2 can be changed, which can better meet the use requirements.

[0038] Further, it further includes a positioning block 1. The positioning block 1 is arranged at the upper end of the positioning plate 2 and is used to press the joint 11 on the housing 10 against one side of the positioning plate 2. As Figure 1 shown, after the housing 10 is locked on the positioning plate 2, the joint 11 is placed on the housing 10 and abuts against the positioning plate 2. After the joint 11 is adjusted, the positioning block 1 can be used to press the joint 11 on the positioning plate 2, playing a positioning role for the joint 11. The structure is simple and the use is convenient.

[0039] Further, it further includes a positioning pin 3. The positioning pin 3 is arranged on the positioning plate 2, and a positioning hole for passing through the positioning pin 3 is formed on the housing 10. As Figure 1 and Figure 2 shown, there are two upper and lower positioning pins 3 arranged on the positioning plate 2, which are inserted into the two upper and lower positioning holes on the housing 10, so as to hang the housing 10 on one side of the positioning plate 2. The structure is simple and the disassembly and assembly are convenient.

[0040] In this embodiment, there are two elastic members 7, one on the left and the other on the right, between the positioning plate 2 and the base 9, enabling the positioning plate 2 to move up and down. Limit blocks 5 are provided at both the left and right ends of the base 9. The positioning plate 2 is located between the two limit blocks 5 on the left and right. The limit blocks 5 can play a role in guiding and limiting, so that the positioning plate 2 can only move up and down between the two limit blocks 5 on the left and right. Limit pins 6 are provided on both the left and right sides of the positioning plate 2. Chute grooves 14 are formed on the two limit blocks 5 on the left and right. The cooperation between the limit pins 6 and the chute grooves 14 can prevent the positioning plate 2 from shifting in the front-rear direction during the up and down movement. The positioning block 1 and the support block 4 are located on the same side of the positioning plate 2. The positioning block 1 is located at the upper end of the positioning plate 2. The positioning block 1 is installed on the positioning plate 2 by bolts, and the distance between the positioning block 1 and the positioning plate 2 can be changed according to actual needs to meet the positioning requirements of different types of connectors 11.

[0041] During use, first pass the positioning pin 3 through the positioning hole on the housing 10, and pass the locking screw 12 through the through hole on the housing 10. Then thread the locking nut 13 onto the locking screw 12 to clamp the housing 10 between the locking nut 14 and the positioning plate 2, thereby positioning the housing 10 on the positioning plate 2. Then install the connector 11 on the top of the housing 10, and use the positioning block 1 to press the connector 11 against the positioning plate 2. Then start the press. During the process of the press fitting the connector 11, the connector 11 pushes the housing 10 downward, the housing 10 drives the positioning plate 2 downward, and the elastic member 7 is compressed until the housing 10 contacts the support block 4, enabling the support block 4 to support the housing 10. When the press fits the connector 11 to the required position on the housing 10, the press moves upward to return to the initial position, and the elastic member 7 returns to its original state, and the positioning plate 2 moves upward to return to the initial position. During the process of press fitting the connector 11, the support block 4 below the housing 10 can effectively support the housing 10, reducing the bearing capacity of the positioning pin 3, thereby reducing the probability of the positioning pin 3 breaking, making the process of press fitting the connector 11 simpler.
