Description

Technical Field

[0001] This utility model relates to the field of terminal processing equipment technology, and in particular to a wire bar clamping fixture. Background Technology

[0002] A terminal wire is an electronic connector consisting of a wire and terminals. Terminals are typically a piece of metal or a tubular structure used to attach to one or both ends of the wire, facilitating a reliable electrical connection with other circuit components. Terminal wires are widely used inside and outside various electronic devices to transmit signals, data, or power.

[0003] Existing cold-pressed terminals for terminal wires are generally formed by crimping terminals using a terminal crimping machine. After wire feeding, bundling, stripping, and cutting, the terminal piece is directly riveted to the exposed wire core at the end of the wire and then cold-pressed. During processing, the cutting station and the cold-pressing station are not located together. The wire needs to be stripped and cut before it is transferred to the cold-pressing station. During processing, the wire core at the end of the wire should ideally be close to the upper surface of the terminal piece. In the existing technology, to prevent the wire from hitting the terminal piece during transfer, the wire is positioned a certain distance above the terminal piece. However, if the distance is too high, the wire will bend before crimping, and the end of the wire will also be displaced inward due to bending. This prevents the terminal piece from completely covering the end wire core, affecting the crimping quality and resulting in defective products. Therefore, the existing technology requires multiple adjustments to the height of the wire before processing and cannot completely avoid defective products, affecting processing efficiency and leaving room for further improvement. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a wire bar clamping fixture that solves the above-mentioned problem.

[0005] To achieve the above objectives, a wire bar clamping fixture is provided, including a slide block, a fixed sleeve fixedly connected to the upper center of the slide block, a lead screw nut fixedly connected to one side of the slide block, a rotating sleeve provided on the upper inner side of the fixed sleeve, a return spring provided on the inner side of the rotating sleeve, a rotating motor provided at the lower interior of the fixed sleeve, a transmission key provided at the center of the interior of the rotating sleeve, a wire inlet seat fixedly connected to the top of the rotating sleeve, a pressure seat fixedly connected above the wire inlet seat, and a pressure rod provided above the pressure seat.

[0006] The inlet seat has a fixed connection to the outlet seat at one end. A pressure groove is provided at the top of the inlet seat near the outlet seat. A fixed shaft is fixedly connected to the inside of the pressure groove. An L-shaped rotating pressure block is rotatably connected to the inside of the pressure groove through the fixed shaft.

[0007] According to the aforementioned wire rod clamping fixture, a lead screw passing through a lead screw nut is provided on the side of the slide block, and a servo motor is provided at the end of the lead screw. A slide rail corresponding to the lead screw is slidably connected to the bottom of the slide block.

[0008] According to the aforementioned wire rod clamping fixture, the top of the top pressure rod is fixedly connected to the lifting seat of the terminal crimping machine via a spring buffer, and a plastic buffer sleeve is fixedly sleeved on the bottom of the top pressure rod.

[0009] According to the aforementioned wire clamping fixture, the middle of both the inlet and outlet wire seats is provided with multiple wire bundling holes, and a wire bundling sleeve is fixedly connected to the outlet wire seat at a position corresponding to the multiple wire bundling holes.

[0010] According to the aforementioned wire rod clamping fixture, the output end of the rotating motor is slidably connected to the rotating sleeve via a transmission key.

[0011] According to the aforementioned wire rod clamping fixture, the output end of the clamping cylinder is rotatably connected to a transmission plate through a top pressure seat, and the end of the transmission plate away from the top pressure seat is rotatably connected to the top of an L-shaped rotating pressure block.

[0012] The above solution has at least one of the following beneficial effects:

[0013] 1. The present invention has a fixed sleeve and a rotating sleeve nested between the slide and the inlet seat. With the help of the transmission slide key and the return spring, the inlet seat can have a certain downward movement space without affecting the rotation. In addition, with the top pressure rod connected to the lifting seat of the terminal crimping machine, the terminal crimping machine can press the top pressure seat through the top pressure rod during operation, so that the fixed wire strip end falls directly onto the corresponding terminal piece, avoiding the defect problem caused by wire bending and enhancing the practicality of the device.

[0014] 2. The top of the top pressure rod of this utility model is equipped with a spring buffer, which, together with the plastic buffer sleeve at the bottom, can buffer the top pressure rod when it hits the top pressure seat, thereby reducing the noise and vibration intensity generated by the impact. At the same time, it retains a certain buffer margin so that the lifting seat of the terminal crimping machine will not be stuck and can continue to move downward to complete the remaining crimping work, thus enhancing the practicality of the device.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4This utility model provides a wire bar clamping fixture, including a slide block 1. A lead screw nut 3 is fixedly connected to one side of the slide block 1. A lead screw passing through the lead screw nut 3 is provided on the side of the slide block 1, and a servo motor is provided at the end of the lead screw. A corresponding slide rail is slidably connected to the bottom of the slide block 1, and the slide block 1 can be driven to slide by the servo motor. A fixed sleeve 2 is fixedly connected to the upper middle part of the slide block 1. A rotating sleeve 4 is provided on the upper inner side of the fixed sleeve 2. A return spring 6 is provided on the inner side of the rotating sleeve 4. A rotating motor 13 is provided inside the lower part of the fixed sleeve 2. A transmission key 5 is provided at the center of the rotating sleeve 4. The transmission key 5 has a maximum stroke limit. The output end of the rotating motor 13 is slidably connected to the rotating sleeve 4 through the transmission key 5. A wire inlet 7 is fixedly connected to the top of the rotating sleeve 4. A top pressure seat 15 is fixedly connected above the 7, and a top pressure rod 16 is provided above the top pressure seat 15. The top of the top pressure rod 16 is fixedly connected to the lifting seat of the terminal crimping machine through a spring buffer, and a plastic buffer sleeve is fixedly sleeved at the bottom of the top pressure rod 16. This utility model is provided with a nested fixed sleeve 2 and a rotating sleeve 4. With the help of the transmission slide key 5 and the return spring 6, the wire feed seat 7 can have a certain downward space without affecting the rotation. With the help of the top pressure rod 16 connected to the lifting seat of the terminal crimping machine, when the terminal crimping machine is working, the end of the wire is already above the terminal piece. Then, the descent of the lifting seat causes the top pressure rod 16 to press against the top pressure seat 15, so that the fixed end of the wire falls directly onto the corresponding terminal piece. The wire itself will not bend, avoiding the defect problem caused by the bending of the wire.

[0025] A wire feed seat 8 is fixedly connected to the discharge end of the wire feed seat 7. Multiple wire bundling holes are opened in the middle of both the wire feed seat 7 and the wire feed seat 8. Wire bundling sleeves 14 are fixedly connected to the end of the wire feed seat 8 away from the wire feed seat 7 at positions corresponding to the multiple wire bundling holes to stabilize the wire arrangement. A wire pressing groove 9 is opened at the upper end of the wire feed seat 7 near the wire feed seat 8. A fixed shaft 10 is fixedly connected to the inner side of the wire pressing groove 9. An L-shaped rotating pressing block 11 is rotatably connected to the inside of the wire pressing groove 9 through the fixed shaft 10. A clamping cylinder 12 is fixedly connected to the end of the top pressing seat 15 away from the wire feed seat 8. A transmission plate 17 is rotatably connected to the output end of the clamping cylinder 12 through the top pressing seat 15. The end of the transmission plate 17 away from the top pressing seat 15 is rotatably connected to the upper part of the L-shaped rotating pressing block 11. When the wire strip passes through the wire pressing groove 9, the L-shaped rotating pressing block 11 can be driven to rotate by the clamping cylinder 12 to press the wire strip below, thereby clamping and fixing the wire strip.

[0026] Working Principle: In operation, the fixed sleeve 2 and rotating sleeve 4 nested between the slide 1 and the inlet seat 7, along with the transmission key 5 and the return spring 6, allow the inlet seat 7 to have a certain downward movement space without affecting rotation. Combined with the top pressure rod 16 connected to the lifting seat of the terminal crimping machine, the wire end is positioned above the terminal piece during operation. The descent of the lifting seat causes the top pressure rod 16 to press against the top pressure seat 15, causing the fixed wire end to fall directly onto the corresponding terminal piece. This prevents the wire from bending, avoiding defects caused by wire bending. Simultaneously, the spring buffer above the top pressure rod 16, along with the plastic buffer sleeve at the bottom, cushions the impact of the top pressure rod 16 against the top pressure seat 15, reducing noise and vibration intensity. This also provides sufficient buffering margin, preventing the lifting seat of the terminal crimping machine from getting stuck and allowing it to continue moving downwards to complete the remaining crimping work.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
