Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness processing, and in particular relates to a wire harness processing wire feeding mechanism. Background Art

[0002] The wire harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. When processing the wire harness, it is necessary to transmit the wire harness to the designated processing area through the wire feeding mechanism for cutting and other operations.

[0003] In order to avoid the deviation or falling off of the wire harness, the current wire feeding mechanism will tightly fit the upper and lower transmission structures into the wire harness by lifting and lowering, such as the wire feeding mechanism recorded in the announcement number CN209635624U. This patent realizes the clamping and loosening of the wire feeding wheel assembly through the drive of the cylinder.

[0004] However, in the above patent, when the transmission structure is in the process of lifting, it will inevitably come into contact with the shell or the movable groove on the shell. In order to avoid excessive friction and affect the transmission effect during the long-term lifting process, lubricating oil needs to be added regularly. The operating space between the movable groove and the transmission structure is small, so it is relatively inconvenient in actual use. Therefore, there are great limitations in actual use and there is room for improvement. Utility Model Content

[0005] The utility model aims to provide a wire feeding mechanism for wire harness processing, so as to solve the problem that the existing wire feeding mechanism mentioned in the above background technology is inconvenient to operate during use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire harness processing and feeding mechanism, comprising a shell; a transmission component, which is provided with two groups and is arranged on the front surface of the shell in an upper and lower distributed manner; it also includes a placement groove, the cross-section of which is isosceles, the placement groove is opened on the front surface of the shell, and the transmission component covers the outside of the placement groove; a rolling component is arranged in the placement groove, and the rolling component consists of a ball and a removal piece; a plurality of balls are provided and placed in the placement groove in a stacked manner, and the balls are fitted with both sides and the inner end surface of the placement groove, so that part of the balls will be flush with the opening of the placement groove, can be in rolling contact with the transmission component, and can complete the limitation of the balls through the placement groove; a removal piece is arranged in the placement groove, and the removal piece supports the balls at the bottom of the placement groove, so as to facilitate the one-time removal of all the balls later.

[0007] Preferably, a spring is placed inside the placement groove, which counteracts the ball at the top position to reduce the number of balls and can hold the balls tightly. When the transmission component moves upward, it will not drive the balls to move upward synchronously, ensuring that normal lifting is not affected.

[0008] Preferably, the removal piece includes a pull rod symmetrically arranged at two corners inside the placement groove, and a support ring fixed at the bottom end of the pull rod, and the support ring supports the ball at the bottom position. Since all the balls are limited by the placement groove, all the balls can be removed by only pulling the pull rod and then driving the pull rod through the support ring.

[0009] Preferably, a top cover is also installed on the top of the shell, and the top end of the spring is against the top cover, and the spring is pressed tightly by the top cover, so that the spring is forced into a compressed state and can rebound to press the ball tightly.

[0010] Preferably, a cylinder is also installed on the top of the top cover, and the output end of the cylinder passes through the interior of the outer shell and is fixedly connected to the transmission component. The transmission component is driven to rise and fall by the output end of the cylinder. The transmission component includes multiple transmission wheels rotating around their own axes, and synchronous belts mounted on the multiple transmission wheels. The shafts of the multiple transmission wheels pass through the interior of the outer shell, and the ends of the multiple shafts also pass through a plate body, which is not drawn in the figure. The output end of the cylinder is connected to the plate body, and the lifting of the plate body drives the lifting of the entire transmission component, wherein the plate body is a conventional structure, and the same structure as the announcement number can also be set. Since the structural principle of this type is a prior art, it will not be further described here.

[0011] Preferably, a connecting column is fixed to the surface of the shell, and a cleaning roller is sleeved on the connecting column. The cleaning roller is in contact with the synchronous belt. After the wire feeding is completed, the cleaning roller can be used to clean the synchronous belt, wherein the cleaning roller is driven by the friction between the synchronous belt and the cleaning roller when the cleaning roller rotates, and the synchronous belt is driven by a transmission wheel, and the transmission wheel is driven by an external driving structure, wherein the driving structure is outside the shell, not shown in the figure, and is also irrelevant to the improvement of the utility model, so it will not be further described here.

[0012] Preferably, a hole is formed at the end of the connecting column, and a limit pin is inserted into the hole. The top of the limit pin is locked on the connecting column, and the limit pin abuts against the end face of the cleaning roller, thereby limiting the cleaning roller and preventing the cleaning roller from falling.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The rolling assembly in the utility model can achieve rolling fit with the transmission wheel, greatly reducing friction and ensuring that normal lifting and lowering are not affected. At the same time, the rolling assembly can be conveniently taken out from the inside of the shell and is easy to maintain. The overall structure of the rolling assembly is simple and practical.

The top of the limit pin 105 is locked on the connecting column 103, and the limit pin 105 is abutted against the end face of the cleaning roller 104, thereby limiting the cleaning roller 104 and preventing the cleaning roller 104 from falling.
