Description

Technical Field

[0001] This utility model relates to the field of terminal crimping machine technology, and in particular to an electric terminal crimping machine with adjustable pressure. Background Technology

[0002] Tubular terminal blocks belong to the category of cold-pressed terminals. Their main function is to conduct electricity and realize electrical connections. Industrially, they are classified as connectors.

[0003] As industrial automation increases and industrial control requirements become more stringent and precise, the use of tubular terminal blocks is gradually rising. Existing terminal crimping machines generally use a drive mechanism to drive crimping teeth to squeeze the terminal to connect it to the tube. However, the output of the drive mechanism is fixed. After long-term use, the spiral spring connecting the crimping teeth will become fatigued, resulting in unstable pressure. This leads to insufficient pressure applied by the crimping teeth to the terminal, reducing the terminal crimping effect and making it impossible to adjust the pressure applied by the crimping teeth to the terminal as needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the pressure applied to the terminals by the crimping teeth cannot be adjusted as needed, and to propose an electric terminal crimping machine with adjustable pressure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an adjustable pressure electric terminal crimping machine, including a base frame, a mounting plate fixedly connected to the base frame, a crimping mechanism connected to the base frame, a support plate fixedly connected to the upper end of the base frame, a first bearing seat fixedly connected to one side of the support plate, a T-shaped screw rotatably connected to the first bearing seat, a positioning mechanism for limiting the T-shaped screw connected to the first bearing seat, a slide rail fixedly connected to the mounting plate, a movable part slidably connected to the slide rail, the movable part cooperating with the T-shaped screw, a first switch fixedly connected to the movable part, a second fixing plate fixedly connected to the mounting plate, a second switch fixedly connected to the second fixing plate, and a screw head fixedly connected to the crimping mechanism near the first switch.

[0007] Preferably, the base frame is coated with an anti-corrosion layer.

[0008] Preferably, one end of the T-shaped screw is fixedly connected to an adjustment knob.

[0009] Preferably, the adjustment knob is a metal knob with anti-slip texture.

[0010] Preferably, the positioning mechanism includes an indexing turntable, which is fixedly connected to a T-shaped screw, and a positioning bead assembly is fixedly connected to the upper end of the first bearing seat, the positioning bead assembly cooperating with the upper end of the indexing turntable.

[0011] Preferably, the movable component includes a nut seat, which cooperates with a T-shaped screw. A first fixing plate is fixedly connected to the upper end of the nut seat. The first fixing plate is fixedly connected to a first switch component and is slidably connected to a slide rail.

[0012] The present invention provides an electric terminal crimping machine with adjustable pressure, which has the following advantages:

[0013] The screw head reciprocates horizontally between the second and first switching components. The position of the screw head is sensed by the sensing heads on the second and first switching components. When the position of the first switching component changes, the movement position of the screw head changes accordingly, thereby regulating the output pressure of the motor and adjusting the pressure of the pressure teeth on the tubular terminal. The output power of the motor can be adjusted as needed. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-5 An adjustable pressure electric terminal crimping machine includes a base frame 1 coated with an anti-corrosion layer, a mounting plate 2 fixedly connected to the base frame 1, a crimping mechanism connected to the base frame 1, a support plate 21 fixedly connected to the upper end of the base frame 1, a first bearing seat 22 fixedly connected to one side of the support plate 21, a T-shaped screw 23 rotatably connected to the first bearing seat 22, one end of the T-shaped screw 23 passing through the first bearing seat 22 and the support plate 21, and an adjusting knob 25 fixedly connected to one end of the T-shaped screw 23. The adjusting knob 25 is a metal knob with anti-slip texture. The other end is connected to the base frame 1 through the second bearing seat 24. The first bearing seat 22 is connected to a positioning mechanism 26 for limiting the T-shaped screw 23. The mounting plate 2 is fixedly connected to a slide rail 28. The slide rail 28 is slidably connected to a movable part 27. The movable part 27 cooperates with the T-shaped screw 23. The movable part 27 is fixedly connected to a first switch 29. The mounting plate 2 is fixedly connected to a second fixing plate 30. The second fixing plate 30 is fixedly connected to a second switch 31. The screw head 32 is fixedly connected to the side of the pressing mechanism near the first switch 29.

[0022] The crimping mechanism includes a mounting base 5, which is fixedly connected to the base frame 1. A nut 7 is rotatably connected inside the mounting base 5. A support base 6 is fixedly connected to the mounting plate 2. A screw 10 is threaded through the support base 6 and connected to the nut 7. One end of the screw 10 is connected to a screw head 32. A motor 3 is fixedly connected to the mounting plate 2. The output end of the motor 3 is connected to the nut 7 through a transmission mechanism. A protective mechanism is fixedly connected to the support base 6. One end of the screw 10 extends into the protective mechanism and is connected to a gear ring 14 through a pushing mechanism. The gear ring 14 is a spiral structure gear ring, which does not require adjustment when crimping terminals of different sizes, making it more convenient to use. A pressing tooth 15 is connected to the gear ring 14. Second clamping plates 20 are connected to both sides of the inner wall of the protective mechanism. The pressing tooth 15 is rotatably connected to the second clamping plates 20 through several sixth connecting shafts. A positioning protection plate 19 is connected to each second clamping plate 20. The positioning protection plate 19 facilitates terminal positioning and crimping, improving work efficiency.

[0023] The positioning mechanism 26 includes an indexing turntable 261, which is fixedly connected to a T-shaped screw 23. A positioning bead assembly 262 is fixedly connected to the upper end of the first bearing seat 22, and the positioning bead assembly 262 cooperates with the upper end of the indexing turntable 261.

[0024] The movable component 27 includes a nut seat 271, which cooperates with the T-shaped screw 23. The upper end of the nut seat 271 is fixedly connected to a first fixing plate 272, which is fixedly connected to a first switch component 29 and slidably connected to a slide rail 28.

[0025] Work process:

[0026] After the motor 3 is powered on and started, it drives the transmission mechanism to rotate. The transmission mechanism drives the nut 7 to rotate. After the nut 7 rotates, the screw 10 reciprocates in the horizontal direction. The screw 10 drives the push mechanism to move. After the push mechanism moves, it drives the gear ring 14 to rotate. The gear ring 14 drives the pressing tooth 15 to rotate to crimp the tubular terminal.

[0027] Initially, the side of the screw head 32 contacts the end of the second switch 31. After the screw 10 moves horizontally, it drives the screw head 32 to move. After the screw head 32 moves a certain distance, it contacts the first switch 29. At this time, the screw 10 drives the screw head 32 to move in the opposite direction to reset. The T-shaped screw 23 is rotated by adjusting the knob 25. After the T-shaped screw 23 rotates, the nut seat 271 moves horizontally. The nut seat 271 drives the first fixing plate 272 to move. The first fixing plate 272 moves smoothly under the guidance of the slide rail 28. The first fixing plate 272 drives the first switch 29 to move. After the first switch 29 moves, it measures the distance between itself and the screw head 32 in cooperation with the second switch 31. After the first switch 29 moves, the distance between itself and the screw head 32 changes.

[0028] The screw head 32 reciprocates horizontally between the second switch 31 and the first switch 29. The position of the screw head 32 is sensed by the sensing heads on the second switch 31 and the first switch 29. After the position of the first switch 29 changes, the movement position of the screw head 32 changes accordingly, thereby regulating the output pressure of the motor 3, and thus adjusting the pressure of the pressure tooth 15 on the tubular terminal. The output power of the motor 3 can be adjusted as needed.

[0029] After the T-screw 23 rotates, it also drives the indexing turntable 261 to rotate. After the T-screw 23 stops rotating, the positioning bead assembly 262 limits and fixes the indexing turntable 261, thereby limiting and fixing the T-screw 23 so that the T-screw 23 will not rotate.

[0030] Example 2: In Example 1, referring to Figure 3 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the transmission mechanism includes a first pulley 8, which is fixedly connected to the nut 7. A second pulley 9 is connected to the output end of the motor 3. The second pulley 9 is connected to the first pulley 8 through a belt 4. The output end of the motor 3 drives the second pulley 9 to rotate. The second pulley 9 drives the first pulley 8 to rotate through the belt 4. The first pulley 8 drives the nut 7 to rotate.

[0031] Example 3: In Example 1, when the gear ring 14 is rotated, the rotation of the gear ring 14 is not stable. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the pushing mechanism includes a first connecting piece 11. One side of the first connecting piece 11 is rotatably connected to the screw 10 via a first connecting shaft. The other side of the first connecting piece 11 is rotatably connected to a lever 12 via a second connecting shaft. The lever 12 is rotatably connected to the protective mechanism via a third connecting shaft. A second connecting plate 13 is rotatably connected to the lever 12 via a fourth connecting shaft. The second connecting plate 13 is connected to the gear ring 14 via a fifth connecting shaft. After the screw 10 moves in the horizontal direction, it drives the lever 12 to move via the first connecting piece 11. The lever 12 rotates around the third connecting shaft. The lever 12 drives the second connecting plate 13 to move. The second connecting plate 13 drives the gear ring 14 to rotate smoothly.

[0032] Example 4: In Example 1, the exposed toothed ring 14 and pressure tooth 15 reduce the aesthetics of the device. (Refer to...) Figure 4As another preferred embodiment of this utility model, the difference from embodiment 1 is that the protective mechanism includes two parallel first clamping plates 18, which are fixedly connected to the support base 6. The first clamping plates 18 are rotatably connected to the third connecting shaft. The first clamping plates 18 are fixedly connected to the second clamping plate 20. Two parallel support plates 17 are connected between the two first clamping plates 18. A protective cover 16 is fixedly connected between the two support plates 17. The protective cover 16 covers the toothed ring 14 and the pressure tooth 15, improving the aesthetics of the device.
