Description

Technical Field

[0001] The utility model particularly relates to a cutting device for automobile wire harness production. Background Art

[0002] Existing devices for cutting automobile wire harnesses include an operating table, and a cutting knife is arranged on the operating table. In order to prevent the automobile wire harness from shifting during the cutting process, a limiting structure for limiting the wire harness is arranged on the operating table. The existing limiting structure includes an upper box body and a lower box body, and grooves are respectively formed between the upper box body and the lower box body. When the upper box body is installed on the lower box body, the two grooves enclose a channel for limiting the wire harness. At this time, one end of the wire harness passes through the channel and then is placed under the cutting knife for cutting; however, the following problems are found during the cutting process:

[0003] Since the number of wire harnesses cut at one time is random, and the channel formed by enclosing the two grooves is preset during the factory design, that is, when the number of wire harnesses is small, when the wire harness is unrolled from the winding roller and passes through the channel, the wire harness is prone to shift in the channel.

[0023] A cutting device for automobile wire harness production, referring to Figure 1 - Figure 2 , includes an operating table 1. A cutting knife assembly is arranged at one end of the operating table 1, and a tensioning mechanism is arranged at the other end. A number of limiting structures for the wire harness 2 to pass through are arranged on the operating table 1 between the cutting knife assembly and the tensioning mechanism. The tensioning mechanism includes symmetrically arranged vertical plates 31. A first auxiliary roller 32 and a second auxiliary roller 321 are arranged between the two vertical plates 31. A driving roller 33 is arranged between the first auxiliary roller 32 and the second auxiliary roller 321. Adjusting members are arranged at both ends of the driving roller 33, and the adjusting members are connected to the corresponding vertical plates 31.

[0024] Further, the adjusting member includes a movable groove 41 arranged on the vertical plate 31. A moving block 42 is slidably arranged in the movable groove 41. An elastic member 43 is arranged between the moving block 42 and the inner top wall of the movable groove 41. The end of the driving roller 33 is connected to the moving block 42.

[0025] Further, the elastic member 43 is a spring.

[0026] Further, the limiting structure includes a first box body 51 and a second box body 52. Grooves 53 are formed on both the first box body 51 and the second box body 52. When the first box body 51 is installed on the second box body 52, two corresponding grooves 53 enclose a channel for the wire harness 2 to pass through.

[0027] Further, the longitudinal section of the channel is rectangular.

[0028] Further, both ends of the first auxiliary roller 32 are rotatably arranged on the vertical plate 31.

[0029] Further, both ends of the second auxiliary roller 321 are rotatably arranged on the vertical plate 31.

[0030] The working principle of the present utility model is:

[0031] As Figure 1As shown, the wire harness 2 on the rewinding roller (not shown in the figure) is unwound and placed on the cutting device. In this application, the working scenario of synchronously cutting 9 wire harnesses 2 is taken as Example 1 to illustrate the design concept of this application. There are 2 limiting structures arranged on the operating table 1. Taking the cooperation of the upper box body and the lower box body as an example of the limiting structure, 3 grooves 53 are opened on the upper box body, and 3 grooves 53 are also opened on the lower box body. Then the limiting structure has 3 channels, and each channel only allows 3 wire harnesses 2 to pass through; one end of the wire harness 2 is located below the cutter, and the other end passes through the tensioning mechanism. The arrangement of the wire harness 2 is as Figure 1 shown. The wire harness 2 sequentially passes above the first auxiliary roller 32, below the driving roller 33, and above the second auxiliary roller 321. When the driving roller 33 moves downward, the wire harness 2 will be in a tensioned state. Since the tensioning mechanism has a tensioning force on the wire harness 2, and the driving roller 33 has a downward positioning force on the wire harness 2, even if the number of wire harnesses 2 is small, when the wire harness 2 passes through the channels on the limiting structure, it is not easy to shift under the action of external force, as Figure 1 shown. After the position of the wire harness 2 is adjusted, the cutter can be moved downward to cut the wire harness 2. The cutter can be arranged on the mounting frame 1-1, and the mounting frame 1-1 is driven by a rotating motor to rotate and swing, so as to drive the cutter to cut the wire harness 2; the cutter can also be installed on the mounting frame 1-1, and then a telescopic cylinder is connected to the mounting frame 1-1, and the cutter is driven to move up and down by the telescopic cylinder to cut the wire harness 2. Since how the cutter assembly cuts the wire harness 2 belongs to the conventional means in the technical field of the present application and is not the main design concept of this application, it will not be elaborated herein.

[0032] On the basis of the above technical solution, considering that the types of the wire harness 2 are different, the diameter of the wire harness 2 will also change; therefore, in this application, adjusting members are respectively connected to both ends of the driving roller 33. As Example 1, the structural cooperation of the adjusting member can be that a movable groove 41 is opened on the vertical plate 31, a moving block 42 is slidably arranged on the movable groove 41, and the end of the driving roller 33 can be selected to be inserted or fixed to the moving block 42 by bolts. An elastic member 43 is arranged between the moving block 42 and the inner top wall of the movable groove 41. When the diameter of the wire harness 2 changes, the wire harness 2 is placed below the driving roller 33, and the driving roller 33 is manually lifted. At this time, the elastic member 43 will deform. The driving roller 33 is released, and the driving roller 33 moves downward under its own gravity and stretches the elastic member 43. When the driving roller 33 presses on the wire harness 2, the driving roller 33 stops moving. It should be noted here that although the wire harness 2 will undergo slight deformation during the tensioning process of the driving roller 33 on the wire harness 2, it does not affect the use performance of the wire harness 2. The driving roller 33, the first auxiliary roller 32, and the second auxiliary roller 321 are preferably realized by rubber rollers. Such a design can reduce the damage to the wire harness 2. The above elastic member 43 can be realized by a spring.

[0033] Through the cooperation of structures such as a limiting structure and a tensioning mechanism in this application, when the wire harness is tensioned by the tensioning mechanism, even if there is a small amount of wire harness, it is not easy to shift on the limiting structure.

[0034] Although the present utility model has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the present utility model without departing from the principles and spirit scope defined by the claims. Therefore, the detailed description of the embodiments of this disclosure is only used to explain, rather than to limit the present utility model, and the scope of protection is defined by the content of the claims.
