[0033] Refer to Figure 1-7, which is an embodiment of the present invention, provides a fixed-length cutting device for the production and processing of electronic wire harnesses, including: a box body unit 100. The box body unit 100 includes a processing box 101. An inlet 102 is provided on the right side of the processing box 101, and the inlet 102 penetrates to the left side of the processing box 101.

A power component 204 with a power transmission function is provided on the outer side of the rotating shaft 202, and the rotating shaft 202 is connected to the adjusting component 203 through the power component 204. A stabilizing component 205 with a function of adjusting the placement position is provided on the inner side of the processing box 101, and the stabilizing component 205 is located between the storage box 103 and the adjusting component 203. A cutting component 206 with a cutting function is provided on the side of the stabilizing component 205 away from the inlet 102. An auxiliary component 207 with an auxiliary cutting function is provided between the stabilizing component 205 and the cutting component 206; Specifically, when using this device, the electronic wire harness needs to be fed into the inner side of the processing box 101 through the inlet 102. From the hole of the inlet 102 opened on the right side of the processing box 101, start this device. The motor 201 drives the operation of the power component 204 structure through the rotating shaft 202. The power component 204 structure drives the operation of the overall adjusting component 203 structure. When the electronic wire harness enters the adjusting component 203 structure, it will be automatically adjusted according to the outer diameter of the electronic wire harness, so that the adjusting component 203 structure cooperates with the electronic wire harness. Then the power component 204 structure drives the adjusting component 203 structure to operate to convey the electronic wire harness. The adjusting component 203 structure drives the stabilizing component 205 structure to adjust. The rotating shaft 202 structure drives the cutting component 206 structure to operate to cut the electronic wire harness after the cutting opening is adjusted to be parallel by the stabilizing component 205 structure. The electronic wire harness is fixed by the adjusted stabilizing component 205 structure to prevent the incision from tilting due to the deviation of the angle during the cutting process of the cutting component 206 structure, thereby ensuring the cutting quality of the device for the electronic wire harness. By setting the overall structure of the auxiliary component 207, the cutting frequency of the cutting component 206 structure can be automatically adjusted in time when the outer diameter of the electronic wire harness changes, so as to adapt to the length deviation caused by the thickness, and the cutting accuracy of this device is improved.

[0034] Refer to Figure 2-5As shown in the figure, the adjusting assembly 203 includes a plurality of lifting brackets 2031 arranged on the inner side surface of the processing box 101. Six first connecting rods 2035 are arranged on the inner side surface of the lifting brackets 2031, and the first connecting rods 2035 are rotatably connected to the lifting brackets 2031. A first pressing roller 2036 is arranged on the outer side surface of the first connecting rods 2035. A first connecting bracket 2032 is arranged on the side of the lifting bracket 2031 away from the feeding port 102, and the upper and lower first connecting brackets 2032 are arranged staggeredly. A first gear 20310 is arranged between the two first connecting brackets 2032. A first connecting shaft 2039 is arranged on the inner side surface of the first gear 20310, and the first connecting shaft 2039 is rotatably connected to the processing box 101. A first telescopic rod 2033 is arranged on the side of the lifting bracket 2031 away from the feeding port 102, and the first telescopic rod 2033 is located at the middle position on the side of the lifting bracket 2031 away from the feeding port 102. A first spring 2034 is sleeved on the outer wall of the first telescopic rod 2033; Specifically, when using this device, the electronic wire harness enters the range of the adjusting assembly 203 on the inner side of the processing box 101 through the feeding port 102 on the right side. The electronic wire harness will squeeze the structure of the adjusting assembly 203 arranged on the upper and lower sides through its own thickness, so that the structure of the adjusting assembly 203 drives the lifting bracket 2031 to move through the first connecting rod 2035. When the thickness of the electronic wire harness is relatively thick, the distance between the upper and lower lifting brackets 2031 is extended. The lifting bracket 2031 will squeeze the first spring 2034, causing the first telescopic rod 2033 and the first spring 2034 to contract. At the same time, due to the staggered arrangement of the first connecting brackets 2032 and the first gear 20310 between the two first connecting brackets 2032 remaining stable, both the upper and lower first connecting brackets 2032 apply pressure to the first gear 20310, so that the lifting bracket 2031 remains in a stable state after moving, and there will be no deviation in the front and rear sides of the lifting bracket 2031. Through the pressure applied to the first gear 20310 by the first connecting brackets 2032 on both sides at the same time, the stability of the structure during use is ensured.

A conveyor belt 2037 is arranged between the outer side surfaces of the six first pressing rollers 2036. A first tooth socket matching the first gear 20310 is opened on the outer side surface of the first connecting bracket 2032; Specifically, by setting the structure of the limiting groove 2038, the moving position of the electronic wire harness is limited to prevent the electronic wire harness from shifting during movement. At the same time, the combined use of the upper and lower limiting grooves 2038 will not hinder the movement of the electronic wire harness. In cooperation with the first spring 2034, it has the effect of straightening the electronic wire harness to prevent the electronic wire harness from bending and causing errors in cutting. By setting the second helical gear 2076 in cooperation with the limiting groove 2038, it prevents the groove of the limiting groove 2038 from causing indentations on the surface of the electronic wire harness, thereby maintaining the integrity of the surface of the electronic wire harness. By setting the limiting groove 2038 to drive the electronic wire harness for transportation, there will be no intermittent movement, maintaining the uniform movement of the electronic wire harness and ensuring the cutting accuracy.

The structure of the rotating shaft 202 drives the leftmost first connecting rod 2035 to rotate through the first belt 2041, and the first belt 2041 drives the upper first connecting rod 2035 to rotate. The upper first connecting rod 2035 drives the rightmost first pressing roller 2036 to rotate through the conveyor belt 2037. The first pressing roller 2036 drives the upper second gear 2042 to rotate through the first connecting rod 2035. The upper second gear 2042 drives the lower second gear 2042 to rotate through gear meshing, thereby driving part of the structure of the adjustment assembly 203 to operate and conveying the electronic wire harness. The structure of the adjustment assembly 203 and the structure of the power assembly 204 cooperate with each other to enhance the utilization of the structure.

At the same time, the rotating shaft 202 drives the operation of the overall cutting assembly 206 structure as a power transmission structure. The rotating shaft 202 drives the second connecting rod 2062 to rotate through the meshing between the first bevel gear 2061 and the second bevel gear 2063. The second connecting rod 2062 drives the reciprocating lead screw 2064 to rotate through the meshing between the third bevel gear 2065 and the fourth bevel gear 2066. The reciprocating lead screw 2064 drives the pressing plate 2067 to perform reciprocating movement through the reciprocating thread provided on the surface. During the up and down reciprocating movement of the pressing plate 2067, it squeezes the pressure-receiving plate 2068. The pressing plate 2067 squeezes the pressing plate 2056 through the second pressing roller 2069, so that the third bevel gears 2065 on the upper and lower sides fix the electronic wire harness, and then drive the cutting knife 20610 through the pressure-receiving plate 2068 to perform cutting processing on the electronic wire harness at a fixed distance. During the cutting process, the structure of the stabilizing assembly 205 is used to adjust the fixing position according to the thickness of the electronic wire harness. At the same time, after the electronic wire harness is fixed, through the cooperation of the limiting groove 2038 and the conveyor belt 2037, it is possible to ensure that the electronic wire harness is not damaged and its route is not offset without moving the electronic wire harness, thus ensuring the smooth operation of the cutting assembly 206 structure.

A first helical gear 2075 is disposed on the upper end surface of the fourth connecting rod 2073. Four rotating plates 2077 are disposed on one side between two adjacent pressure receiving plates 2068, and the two adjacent rotating plates 2077 are rotatably connected to the pressure receiving plate 2068 on the side away from the feed port 102 through a shaft. A sliding shaft 2078 is disposed on the side of the rotating plate 2077 close to the feed port 102, and the sliding shaft 2078 is slidably connected to the pressure receiving plate 2068. A plurality of balance rods 2079 are provided on the inner side surfaces of the four rotating plates 2077 through threads. Second helical gears 2076 are disposed at both the front and rear ends of the balance rod 2079, and the second helical gears 2076 mesh with the first helical gear 2075. The second helical gear 2076 is connected to the balance rod 2079 located at the middle position of the pressure receiving plate 2068; Specifically, the structure of this component uses the second connecting shaft 2052 as a power transmission structure to apply the power generated during the adjustment process of the adjustment component 203 structure to the structure of the auxiliary component 207 to adjust the overall structure of the auxiliary component 207. The second connecting shaft 2052 drives the third connecting rod 2071 to rotate. The third connecting rod 2071 drives the fourth connecting rod 2073 to rotate through the meshing between the fifth bevel gear 2072 and the sixth bevel gear 2074. The fourth connecting rod 2073 drives the balance rod 2079 at the middle position to rotate through the meshing between the first helical gear 2075 and the second helical gear 2076. During the rotation of the balance rod 2079, the sliding shaft 2078 is driven to move through the threads provided on the surface. The combination of the sliding shaft 2078 and the balance rod 2079 forms the structure of a ball screw, which will not affect the adjustment of the structure and makes the structure adjustment smooth. The balance rod 2079 drives the distance between the front and rear groups of rotating plates 2077 to decrease respectively through the different threads provided on the surface, thereby increasing the distance between the upper and lower pressure receiving plates 2068, and then adjusting the feed frequency of the cutting structure according to the thickness of the electronic wire harness, so as to ensure that the cutting length of the electronic wire harness by the cutting component 206 remains an accurate value, thereby improving the precision of the equipment for cutting the electronic wire harness.

[0040] Refer to Figure 5 And Figure 7 As shown in the figure, a strip pattern is provided between the pressure receiving plate 2068 and the sliding shaft 2078, and a chute matching the pressure receiving plate 2068 is opened on the inner side surface of the processing box 101; Specifically, by setting strip patterns to limit the movement trajectory of the sliding shaft 2078, it is ensured that the sliding shaft 2078 will not deviate during movement, thus ensuring the cutting accuracy of the cutting component 206 structure. By setting a chute, the regularity of the movement of the pressure-receiving plate 2068 is ensured, and the smooth movement of the cutting knife 20610 during use is maintained, thereby ensuring the improvement of the cutting state of the electronic wire harness by this device.

[0041] Working principle: When using this device, the electronic wire harness needs to be fed into the inside of the processing box 101 through the feeding port 102. From the opening of the feeding port 102 on the right side of the processing box 101, start this device. The motor 201 drives the operation of the power component 204 structure through the rotating shaft 202. The power component 204 structure drives the operation of the overall adjustment component 203 structure. When the electronic wire harness enters the adjustment component 203 structure, it will be automatically adjusted according to the outer diameter of the electronic wire harness, so that the adjustment component 203 structure cooperates with the electronic wire harness. Then, the power component 204 structure drives the adjustment component 203 structure to operate and convey the electronic wire harness. The adjustment component 203 structure drives the stable component 205 structure to adjust. The rotating shaft 202 structure drives the cutting component 206 structure to operate and cut the electronic wire harness after the cutting port is adjusted to be parallel by the stable component 205 structure. The electronic wire harness is fixed by the adjusted stable component 205 structure to prevent the cutting inclination caused by the angle deviation during the cutting process of the cutting component 206 structure, thereby ensuring the cutting quality of the device for the electronic wire harness. By setting the overall structure of the auxiliary component 207, when the outer diameter of the electronic wire harness changes, the cutting frequency of the cutting component 206 structure can be automatically adjusted in a timely manner, so as to adapt to the length deviation caused by thickness, and the cutting accuracy of this device is improved.
