Description

Technical Field

[0001] This utility model belongs to the field of automotive cable crimping technology, and in particular relates to an automotive cable crimping device. Background Technology

[0002] Automotive cables are cables used in automobiles. Their main structure includes the cable part and the terminal pressed at the end of the cable. Specifically, the terminal has a slot that snaps into the cable connector. After the terminal is fitted into the cable connector, it needs to be locked and tightened. Specifically, because the metal material of the terminal is locked, the terminal deforms regularly and is pressed tightly onto the cable without loosening.

[0003] In the manufacturing and processing of automotive cables, the small size of the terminals and the small diameter of the cables make the pressing process quite difficult, particularly in terms of ease of operation. Therefore, in actual practice, the terminals are pre-attached to the cable connectors, and then inserted into a pressing mold, where they are pressed in place by the protruding structures within the mold. During the pressing process, the operator needs to firmly grasp the small-diameter cable, and as the pressing head impacts the cable, the terminals at the cable ends are pressed in place.

[0004] However, in actual operation, it was found that when the hands are sweaty and wet, the cable end is easily slipped off the operator's hands when pressure is applied, resulting in a "slippage phenomenon". This leads to the terminal not being able to be tightly pressed and the pressing depth being insufficient, which can easily cause poor electrical contact between the terminal and the cable.

[0005] Therefore, in actual operation, operators need to wear gloves. However, wearing gloves reduces hand dexterity, and the terminals (which are small and difficult to handle) need to be pre-attached to the cable ends. As a result, in actual operation, wearing gloves makes crimping easier, but pre-attaching terminals is inconvenient. On the other hand, removing gloves makes hand dexterity higher, pre-attaching terminals is convenient, but crimping is not stable enough.

[0006] Therefore, the aforementioned technical defects are important factors leading to low efficiency and low pass rate of cable terminal pressing. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide an automotive cable crimping device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A car cable crimping device includes a track frame, one end of which is fitted with a cable end crimping structure, and the other end of which is fitted with a cable positioning structure for positioning cables.

[0010] The cable end pressing structure includes a pressing mold, which is pushed by a first pushing structure;

[0011] The cable positioning structure includes a positioning sleeve for positioning the cable, and a number of positioning structures for positioning and locking the cable are installed on the positioning sleeve. The cable positioning structure also includes a second pushing structure that pushes the positioning sleeve toward the pressing mold.

[0012] Preferably, the track frame includes track rods spaced apart at the front and rear, with end seats fixedly connected to the ends of the track rods, and a plurality of fasteners fixedly installed on the end seats, and the track frame is fixedly installed by means of fasteners.

[0013] Preferably, the pressing mold includes a pressing sleeve, and a plurality of sloped pressing plates with a sloping structure are fixedly connected inside the pressing sleeve, the slope height of the pressing plates gradually increasing from the outer end to the inner end;

[0014] The press-fit sleeve is fixedly connected to a slide plate that is slidably connected to the track rod.

[0015] Preferably, a first spring is sleeved on the left end of each track rod, and the two ends of the first spring are respectively fixedly connected to the side walls of the slide and the end seat facing each other.

[0016] Preferably, the first pushing structure includes a first cylinder that is fixedly installed at the top and bottom positions of the left end seat, and the piston rod of the first cylinder is fixedly installed on the slide plate.

[0017] Preferably, the two ends of the positioning sleeve are respectively fixedly connected to the protrusions that are slidably connected to the track rod, and the right end of the track rod is sleeved with a second spring, the two ends of the second spring being fixedly connected to the protrusion and the end seat respectively.

[0018] Preferably, the second pushing structure includes a second cylinder that is fixedly connected to the top and bottom positions of the right end seat respectively;

[0019] The piston rod of the second cylinder is fixedly connected to the positioning sleeve, and the positioning sleeve is fixedly connected to the fixing boss that is fixedly connected to the piston rod.

[0020] Preferably, the positioning structure includes a plurality of straight-arranged pressing wheels located inside the positioning sleeve, and a sliding rod that passes through the positioning sleeve is fixedly connected to the pressing wheel;

[0021] The positioning structure also includes a pusher fixedly connected between the tops of several slide rods; a pusher cylinder is mounted on the top of the pusher.

[0022] The cable positioning structure also includes an annular seat, and the cylinder of the push cylinder is fixedly installed on the inner side wall of the annular seat.

[0023] Preferably, the pressing wheel has a pressing groove.

[0024] This utility model has the following beneficial effects:

[0025] 1. During the operation, the cable is inserted into the positioning sleeve and positioned by the circumferentially distributed positioning structure, thereby facilitating the subsequent pressing.

[0026] Subsequently, under the push of the second pushing structure (second cylinder) and the first pushing structure, the positioning cable is pressed into the inside of the pressing sleeve. After pressing is completed, with the assistance of the elastic restoring force of the second spring and the first spring, the pressing sleeve and the positioning sleeve quickly move away, thus facilitating the release of the cable.

[0027] 2. The positioning structure includes a pusher fixedly connected between the tops of three slide rods. A pusher cylinder is mounted on the top of the pusher, creating channels between the pressure rollers in the circumferentially distributed positioning structure. The cable passes through these channels, and then, under the synchronous operation of the pusher cylinder, all the pressure rollers move closer together and press against the cable. Driven by the pusher cylinder, all the pressure rollers move closer together and press against the outer wall of the cable, causing the cable sheath to engage in the pressure grooves. This maintains high friction, preventing slippage and backing during the pressing process.

[0028] Because the cable is positioned by multiple segments of compression, it maintains high stability during the pressing process. This method not only greatly improves the pass rate of pressing, but also enhances the convenience and operability of cable pressing.

[0029] The aforementioned cable positioning structure also includes an annular seat, and the cylinder of the push cylinder is fixedly mounted on the inner side wall of the annular seat. Attached Figure Description

[0040] Example 1

[0041] like Figure 1-5 As shown, an automotive cable crimping device includes a track frame. The specific structure of the track frame is as follows: the track frame includes track rods 2 arranged at intervals in the front and rear, and end seats 3 are fixedly connected between the ends of the track rods 2. A pair of fasteners arranged at intervals in the front and rear are fixedly installed on the end seats 3, and the track frame is fixedly installed by the fasteners.

[0042] Specifically, the fastener includes a screw 31 fixed on the end seat 3, with a fastening sleeve threaded to the end of the screw 31, and a connecting screw 32 fixedly connected to the fastening sleeve. In the working process, according to the method disclosed in the prior art, the connecting screw 32 is fastened to the working frame by rotating the fastening sleeve, so that the entire device is suspended and installed.

[0043] In order to achieve efficient, flexible and precise cable and end pressing, the left end of the above-mentioned track frame is equipped with a cable end pressing structure 1, and the right end of the track frame is equipped with a cable positioning structure 4 for positioning cables.

[0044] During operation, the cable to be pressed is positioned by the cable positioning structure 4, and then the terminal is pressed onto the cable by the cable end pressing structure 1.

[0045] Specifically, the cable end pressing structure 1 includes a pressing mold, which is pushed by a first pushing structure.

[0046] Specifically, similar to existing press-fitting structures, the press-fitting mold includes a press-fitting sleeve 11, and a number of circumferentially distributed sloped plates 13 are fixedly connected inside the press-fitting sleeve 11. The slope height of the sloped plates 13 gradually increases from the outer end to the inner end (that is, the gap between the sloped plates 13 gradually decreases from the outer side to the inner side).

[0047] As the terminal penetrates into the pressing mold, and as it continues to enter the pressing sleeve 11, the gap between the pressing plates 13 gradually decreases, and then it is pressed against the outer shell of the terminal. Under the pressure, the terminal shell deforms and is locked at the end of the cable.

[0048] The aforementioned press-fit sleeve 11 is fixedly connected to a slide plate 12 that is slidably connected to the track rod 2.

[0049] Specifically, each of the left ends of the track rod 2 is fitted with a first spring 21, and the two ends of the first spring 21 are respectively fixedly connected to the side walls of the slide plate 12 and the end seat 3 facing each other.

[0050] The first pushing structure includes a first cylinder 14 (the cylinder barrel of the first cylinder 14 is fixedly installed at the top and bottom positions of the left end seat 3 respectively via connecting screw A) and the piston rod of the first cylinder 14 is fixedly installed on the slide plate 12.

[0051] During operation, the first pushing structure drives the slide plate 12, the pressing sleeve 11, and the cable positioning structure 4 to press each other closer together.

[0052] Example 2

[0053] like Figure 1-5As shown, this embodiment, based on the structure of embodiment 1, discloses the specific structure of the cable positioning structure 4 as follows:

[0054] The cable positioning structure 4 includes a positioning sleeve 41 for positioning the cable, and a plurality of positioning structures 42 for positioning and locking the cable are installed on the positioning sleeve 41. The cable positioning structure 424 also includes a second pushing structure that pushes the positioning sleeve 41 toward the pressing mold.

[0055] Specifically, the two ends of the positioning sleeve 41 are respectively fixedly connected to the protrusions 411 that are slidably connected to the track rod 2, and the right end of the track rod 2 is sleeved with a second spring 22. The two ends of the second spring 22 are respectively fixedly connected to the protrusions 411 and the end seat 3.

[0056] Meanwhile, the second pushing structure includes a second cylinder 43 that is fixedly connected to the top and bottom of the right end seat 3 respectively (similarly, the cylinder barrel of the second cylinder 43 is fastened to the top and bottom of the right end seat by connecting screw A respectively).

[0057] The piston rod of the second cylinder 43 is fixedly connected to the positioning sleeve 41. Correspondingly, the positioning sleeve 41 is fixedly connected to the fixing boss that is fixedly connected to the piston rod.

[0058] During operation, the cable is inserted into the positioning sleeve 41 and positioned by the circumferentially distributed positioning structure 42, thereby facilitating the subsequent pressing.

[0059] Subsequently, under the push of the second pushing structure (second cylinder 43) and the push of the first pushing structure, the positioning cable is pressed into the inside of the pressing sleeve 11. After pressing is completed, with the assistance of the elastic restoring force of the second spring 22 and the first spring 21, the pressing sleeve 11 and the positioning sleeve 41 quickly move away, thus facilitating the removal of the cable.

[0060] Example 3

[0061] like Figure 1-5 As shown, based on the structure of embodiment 2, the positioning structure 42 includes several straight-lined pressing wheels 423 located inside the positioning sleeve 41 (the pressing wheels 423 are not distributed, and three are provided, located near the two sides of the positioning sleeve 41 and in the middle of the inner side wall of the sleeve respectively). A sliding rod 4231 that penetrates the positioning sleeve 41 is fixedly connected to the pressing wheel 423 (the sliding rod 4231 is slidably connected to the positioning sleeve 41).

[0062] Meanwhile, the positioning structure 42 also includes a push seat 422 fixedly connected between the tops of the three slide rods 4231; a push cylinder 421 (piston rod fixed at the top center of the push seat) is installed on the top of the push seat 422.

[0063] In the circumferentially distributed positioning structure 42, a channel B is formed between the pressure rollers 423. The cable passes through the channel B, and then, under the synchronous operation of the push cylinder 421, all the pressure rollers 423 move closer to each other and press onto the cable. During operation, the wheel body of the pressure rollers 423 is preferably made of elastic rubber material.

[0064] In order to increase the friction between the cable and the pressure roller 423 (increase the contact area), a pressure groove is provided on the pressure roller 423. Under the push of the push cylinder 421, all the pressure rollers 423 move closer to each other and press against the outer wall of the cable. The sheath of the cable is inserted into the pressure groove, thus maintaining a large friction and preventing slippage during the pressing process.

[0065] Because the cable is positioned by multiple segments of compression, it maintains high stability during the pressing process. This method not only greatly improves the pass rate of pressing, but also enhances the convenience and operability of cable pressing.

[0066] The cable positioning structure 42 also includes an annular seat 4211, and the cylinder of the push cylinder 421 is fixedly installed on the inner side wall of the annular seat 4211.

[0067] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
