Description

Technical Field

[0001] This utility model relates to the field of wire harness processing and production technology, and in particular to a cutting device for power switch wire harness production. Background Technology

[0002] Wire harnesses are used to transmit signals and power between devices. They are mainly used to connect various electrical devices and consist primarily of wires and insulating wrapping materials. During production, wire harnesses are cut to a certain length according to the needs of use.

[0003] Currently, when cutting electronic wire harnesses, operators need to straighten the harness. When cutting the harness, the wires to be cut may be twisted due to pressure, resulting in inaccurate cutting and uneven cut ends of multiple wires.

[0004] In traditional cutting processes, the wire harness is placed on a cutting table. When the blade cuts the taut wire harness, it applies significant mechanical stress to the wires. The wire harness contains multiple wires. When the blade cuts the top wire first and then continues to move downwards, the subsequent wires to be cut are subjected to compressive force. Furthermore, the wire harness being cut may contract due to the lack of restraint, which could lead to twisting. This compressive force and twisting problem can cause inaccurate cutting positions, resulting in uneven cut ends and problems such as uneven cuts and uneven wire ends.

[0005] Therefore, it is necessary to provide a cutting device for the production of power switch wire harnesses to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a cutting device for power switch wire harness production, which solves the problem that when the blade cuts the wire at the top first and then continues to move downwards, the subsequent wires to be cut will be subjected to squeezing pressure, and the wire harness being cut will shrink due to the lack of restraint, which may cause twisting. This squeezing pressure and twisting problem may lead to inaccurate cutting position, resulting in uneven cutting ends and problems such as uneven cuts and uneven wire ends.

[0007] To solve the above-mentioned technical problems, this utility model provides a cutting device for power switch wire harness production, comprising: a shelf; Two vertical plates are respectively disposed on both sides of the top middle of the shelf.

The cutting device includes a first lifting member, a fixing plate, and a cutting blade. The first lifting member is fixedly installed in the middle of the top of the mounting plate. The fixing plate is fixedly installed on the outer surface of the output shaft of the first lifting member. The cutting blade is fixedly installed at the bottom end of the output shaft of the first lifting member. The limiting device comprises two slidably mounted on both sides of the surface of the cutting device. Each limiting device includes a sliding rod, a blocking block, an elastic element, a pressing block, and a first pressing pad. The sliding rod is slidably mounted on both sides inside the fixing plate. The blocking block is fixedly mounted on the top of the sliding rod. The elastic element is sleeved on the bottom of the outer surface of the sliding rod. The pressing block is fixedly mounted on the bottom of the sliding rod. The first pressing pad is disposed at the bottom of the pressing block.

[0008] Preferably, a pressing device is fixedly installed on one side of the top of the shelf. The pressing device includes a support plate, a horizontal plate, a second lifting member, a pressing block, and a second pressing pad. The two support plates are respectively fixedly installed on the front and rear sides of the top side of the shelf. The horizontal plate is fixedly installed on the top of the two support plates. The second lifting member is fixedly installed in the middle of the top of the horizontal plate.

[0014] Compared with related technologies, the cutting device for power switch wire harness production provided by this utility model has the following advantages: This utility model provides a cutting device for power switch wire harness production. By installing limiting devices on both sides of the cutting blade, when the cutting blade descends to cut the wire harness, the pressing block drives the first pressing pad to press the cutting blade against both sides of the cutting position of the wire harness.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

Figure 3 for Figure 1The diagram shows the structure of the pressing device.

[0019] A cutting device for manufacturing power switch wire harnesses includes: a shelf 1; Vertical plates 2 are respectively disposed on both sides of the top middle of the shelf plate 1. The top of the two vertical plates 2 is fixedly connected to the mounting plate 3. A cutting device 4 is disposed in the middle of the top of the mounting plate 3. The cutting device 4 includes a first lifting member 41, a fixing plate 42 and a cutting blade 43. The first lifting member 41 is fixedly installed in the middle of the top of the mounting plate 3. The fixing plate 42 is fixedly installed on the outer surface of the output shaft of the first lifting member 41. The cutting blade 43 is fixedly installed at the bottom end of the output shaft of the first lifting member 41. The limiting device 5 is slidably installed on both sides of the surface of the cutting device 4. The limiting device 5 includes a slide rod 51, a blocking block 52, an elastic element 53, a pressing block 54, and a first pressing pad 55. The slide rod 51 is slidably installed on both sides inside the fixing plate 42. The blocking block 52 is fixedly installed on the top of the slide rod 51. The elastic element 53 is sleeved on the bottom of the outer surface of the slide rod 51. The pressing block 54 is fixedly installed on the bottom of the slide rod 51. The first pressing pad 55 is disposed at the bottom of the pressing block 54.

[0020] A pressing device 6 is fixedly installed on one side of the top of the shelf 1. The pressing device 6 includes a support plate 61, a horizontal plate 62, a second lifting member 63, a pressing block 64, and a second pressing pad 65. The two support plates 61 are fixedly installed on the front and rear sides of the top side of the shelf 1, respectively. The horizontal plate 62 is fixedly installed on the top of the two support plates 61. The second lifting member 63 is fixedly installed in the middle of the top of the horizontal plate 62. The pressing block 64 is fixedly installed at the bottom end of the output shaft of the second lifting member 63. The second pressing pad 65 is disposed at the bottom of the pressing block 64.

[0021] The shelf 1 has a length value of 7 in the middle of its top.

[0022] The elastic element 53 adopts a spring structure. The top end of the elastic element 53 is fixedly connected to the bottom of the fixing plate 42, and the bottom end of the elastic element 53 is fixedly connected to the top of the pressing block 54.

[0023] Both the first pressing pad 55 and the second pressing pad 65 are made of rubber.

[0024] Both the first lifting component 41 and the second lifting component 63 adopt a hydraulic cylinder structure.

[0025] The first pressing pad 55 and the second pressing pad 65 are thicker, which makes it easier to squeeze wire harnesses of different diameters and restrict the wire harnesses. The limiting device 5 is installed on both sides of the cutting blade 43 to press the two ends of the wire harness being cut.

[0026] The restoring elastic force of the elastic element 53 pushes the pressing block 54 downward, and the bottom of the pressing block 54 is lower than the bottom of the cutting blade 43.

[0027] The working principle of the cutting device for power switch wire harness production provided by this utility model is as follows: When working, first place the power switch harness that needs to be cut in the middle of the top of the shelf 1. According to the required cutting length, locate it according to the length value 7 set in the middle of the top of the shelf 1 to ensure that the cutting position of the harness is accurate.

[0028] The second lifting member 63 in the pressing device 6 is activated. The output shaft of the second lifting member 63 drives the pressing block 64 and the second pressing pad 65 to move downward. The second pressing pad 65 presses and fixes the end of the wire harness, and the length is calculated from the end of the wire harness.

[0029] Pulling the other end of the wire harness straightens it, activating the first lifting member 41 in the cutting device 4. The output shaft of the first lifting member 41 drives the fixed plate 42 to move downwards. The fixed plate 42 drives the cutting blade 43 to move downwards. At the same time, when the fixed plate 42 moves downwards, it drives the slide rod 51 to move downwards. The slide rod 51 drives the pressing block 54 and the first pressing pad 55 to move downwards. When the first pressing pad 55 contacts the wire harness, because the bottom height of the first pressing pad 55 is lower than the bottom height of the cutting blade 43, as the fixed plate 42 continues to move downwards, the elastic member 53 is compressed, and the first pressing pad 55 exerts a certain pressure on the wire harness, restricting the movement and twisting of the wire harness during the cutting process.

[0030] Then the fixed plate 42 continues to move downward, so that the cutting blade 43 continues to cut the wire harness downward. After the cutting is completed, the first lifting member 41 moves upward through the output axis, pulling the cutting blade 43 and the limiting device 5 upward to retract, and the cut wire harness is removed, completing one wire harness cutting operation.

[0031] Compared with related technologies, the cutting device for power switch wire harness production provided by this utility model has the following advantages: This utility model provides a cutting device for power switch wire harness production. By installing limiting devices 5 on both sides of the cutting blade 43, when the cutting blade 43 descends to cut the wire harness, the pressing block 54 drives the first pressing pad 55 to press the cutting blade 43 against both sides of the cutting position of the wire harness to be cut. This allows the pressing blocks 54 on both sides to restrict the cutting end of the wire harness as the cutting blade 43 continues to cut downwards, preventing the wire harness from twisting and moving due to the cutting force, keeping the cut surface of the wire harness flat, improving the practicality of the device, preventing the wire harness from shifting or shaking during cutting, and thus ensuring the accuracy of the cutting.

[0035] The drive unit 81 adopts a servo motor structure.

[0036] The threaded block 10 is threaded to the outer surface of the threaded rod 82, and the threaded block 10 can only slide due to the restriction of the groove 9.

[0037] The working principle of the cutting device for power switch wire harness production provided by this utility model is as follows: During operation, the output shaft of the drive component 81 first rotates, causing the threaded rod 82 to rotate. The threaded rod 82 rotates and engages with the threaded block 10. The threaded block 10 slides inside the slide groove 9. The threaded block 10 drives the vertical plate 2 and the cutting device 4 to slide on the top of the shelf plate 1 through the connecting plate 11, adjusting the distance between the cutting device 4 and the pressing device 6.

[0038] Compared with related technologies, the cutting device for power switch wire harness production provided by this utility model has the following advantages: This utility model provides a cutting device for power switch wire harness production.
