Description

TECHNICAL FIELD

[0001] The application relates to the technical field of corrugated pipe cutting, in particular to a corrugated pipe cutting counting device. BACKGROUND

[0002] In the process of automobile wire harness processing, a corrugated pipe is usually arranged on the wire harness, so that workers need to cut a large number of corrugated pipes in the processing factory. At present, the following problems exist in the process of cutting the corrugated pipe in the factory.

[0003] 1. The cutting process of the corrugated pipe lacks counting, and manual counting is needed, and problems such as missing counting and wrong counting exist;

[0004] 2. The cutting position of the corrugated pipe is random at the wave peak or the wave valley, when the wire harness is inserted into the corrugated pipe, the total cross-sectional area of the wire harness capable of being inserted into the corrugated pipe is determined by the wave valley, and the size of the gap between the wire harness and the corrugated pipe at the pipe opening position depends on whether the pipe opening is the wave peak or the wave valley. If the cutting position of the pipe opening is the wave valley, the gap between the wire harness and the corrugated pipe at the pipe opening position will be too small, which is easy to cause abrasion to the insulating skin of the wire harness. Therefore, the best cutting position of the corrugated pipe is the wave peak, and some car companies also require that the cutting position of the corrugated pipe must be at the wave peak position.

[0005] In summary, the problems of being unable to automatically count in the cutting process of the corrugated pipe and being unable to accurately cut at the wave peak position need to be solved. CONTENT OF THE INVENTION

[0038] Embodiments

[0039] Reference Figure 1As shown, the embodiment provides a corrugated pipe cutting counting device, which comprises a base plate 1, a cutter 2, a limiting piece 3, a positioning piece 4, a driving piece 5 and a sensor 6. The base plate 1 can be bolted on the workbench when working. The cutter 2 comprises a cutter seat 21, a cutter body 22 and a counting rod 23. The cutter seat 21 is movably mounted on the base plate 1, and specifically, a first track can be arranged on the base plate 1, so that the cutter seat 21 is in sliding fit with the first track. The counting rod 23 is mounted on the cutter seat 21 and located above the cutter body 22.

[0040] Referring to Figure 2 As shown, the limiting piece 3 comprises two oppositely arranged limiting plate bodies 31, which are fixedly mounted on the base plate 1 and can be connected by welding or bolting. A first gap 32 for accommodating the insertion of the cutter body 22 is formed between the two limiting plate bodies 31, and a limiting hole 33 for accommodating the passage of the corrugated pipe is arranged on the limiting plate. When cutting the corrugated pipe, the corrugated pipe passes through the limiting hole 33, and the cutter 2 is driven to move towards the limiting piece 3, so that the cutter body 22 is inserted into the first gap 32 to cut the corrugated pipe.

[0041] Specifically, referring to Figure 4 As shown, the positioning piece 4 comprises an operating rod 41 and two arc-shaped positioning plates 42. The operating rod 41 is connected with the two arc-shaped positioning plates 42 respectively, and the operating rod 41 is in sliding connection with the limiting plate body 31. Specifically, a second guide rail can be arranged on the limiting plate body 31, so that the operating rod 41 is in sliding fit with the second guide rail, and the worker moves the arc-shaped positioning plates 42 by moving the operating rod 41. A second gap 43 aligned with the center of the first gap 32 is formed between the two arc-shaped positioning plates 42, and the two arc-shaped positioning plates 42 are respectively clamped in the valleys on both sides of the wave crest of the corrugated pipe. It should be noted that the distance between the two arc-shaped positioning plates 42 is just equal to the distance between the two valleys, so that when the two arc-shaped positioning plates 42 are respectively clamped in the valleys on both sides of the wave crest of the corrugated pipe, the middle plane of the wave crest is located at the middle position of the second gap 43, so that the wave crest is aligned with the cutter body 22, and the cutter body 22 can accurately cut the position of the wave crest.

[0042] Specifically, the driving piece 5 is mounted on the base plate 1 and connected with the cutter seat 21, which is used to drive the cutter seat 21 to move towards the limiting piece 3 and control the cutting action of the cutter body 22. The sensor 6 is mounted above the limiting plate body 31 and used to sense the counting rod 23. The number of times the counting rod 23 passes through the sensor 6 can be accurately recorded. As for how to display the number of cutting, the time reporting or display screen display can be used, which are all prior art and will not be described in detail in this embodiment.

[0043] The corrugated pipe cutting counting device provided by the embodiment makes the counting rod 23 move with the cutter body 22, and the cutting counting can be performed by detecting the counting rod 23 through the sensor 6; the two arc-shaped positioning plates 42 position the corrugated pipe on both sides of the wave trough, so that the cutter body 22 always cuts the wave peak position when being inserted into the first gap 32 and the second gap 43, the accurate cutting of the wave peak position can be realized, the friction between the pipe and the wire harness is reduced, and the abrasion of the wire harness insulation sheet is reduced.

[0044] Specifically, still referring to Figure 4 The inner side of the arc-shaped positioning plate 42 is provided with an arc-shaped positioning groove 44; the diameter of the arc-shaped positioning groove 44 is smaller than the outer diameter of the wave peak of the corrugated pipe and greater than or equal to the outer diameter of the wave trough of the corrugated pipe. After the arc-shaped positioning groove 44 is clamped on the wave trough, the corrugated pipe can be positioned in the axial direction, and the worker can determine whether the arc-shaped positioning plate 42 is clamped on the wave trough by pulling the corrugated pipe. If the corrugated pipe cannot be pulled, it indicates that the arc-shaped positioning plate 42 is clamped on the wave trough, so that the cutter body 22 can accurately cut the wave peak position, and the cutting yield is improved.

[0045] Specifically, still referring to Figure 4 The two side surfaces of the arc-shaped positioning groove 44 are respectively provided with a guide inclined surface 45, so that the thickness of the arc-shaped positioning plate 42 gradually increases in the direction away from the inner wall of the arc-shaped positioning groove 44. The guide inclined surface 45 makes the arc-shaped positioning plate 42 more easily enter the wave trough position. In order to avoid the arc-shaped positioning plate 42 cutting the corrugated pipe, the inner wall of the arc-shaped positioning groove 44 is an arc surface 46, rather than an arc-shaped tip.

[0046] Specifically, still referring to Figure 2 The operating rod 41 extends outwardly from the limiting plate body 31, and the spring 47 is connected between the operating rod 41 and the limiting plate body 31, and the spring 47 has a spring force for moving the arc-shaped positioning plate 42 towards the direction of the center line of the limiting hole 33. Before the corrugated pipe passes through the limiting hole 33, the operating rod 41 is pulled outwardly; after the corrugated pipe passes through the limiting hole 33, the arc-shaped positioning plate 42 can be clamped into the wave trough by slowly releasing the operating rod 41. The spring 47 can keep the arc-shaped positioning plate stable after being clamped into the wave trough.

[0047] Specifically, referring to Figure 2 The first gap 32 includes a first part 34 and a second part 35, the first part 34 is used for accommodating the arc-shaped positioning plate 42; and the width of the second part 35 is smaller than the width of the second gap 43. The cutting position of the cutter body 22 is limited by the second part 35, and the width of the second part 35 is smaller than the width of the second gap 43, so that the width of the second part 35 is smaller than the distance between two wave troughs, and the cutter body 22 can cut the wave peak center as much as possible.

[0048] Specifically, continuing to refer to Figure 1 As shown in the figure, the driving member 5 includes a mounting plate 51 and a cylinder; the mounting plate 51 is mounted on the base plate 1, and the mounting plate 51 is provided with a through hole; the cylinder includes a cylinder body 52 and a piston rod 53; the cylinder body 52 is mounted on the mounting plate 51, and the piston rod 53 is movably connected with the cutter seat 21 through the through hole. The mounting plate 51 is also provided with a guide hole, and the cutter seat 21 is connected with a guide rod 54 movably passing through the guide hole. The action of the piston rod 53 is controlled by the cylinder body 52, so that the cutting action of the cutter body 22 on the corrugated pipe can be realized.

[0049] Specifically, the cylinder body 52 is connected with a foot valve 55, and the foot valve 55 controls the movement of the piston rod 53. The foot valve 55 is a mature product on the market, and the action of the piston rod 53 controlled by the foot valve 55 is also a mature prior art, so it is not described in detail in this embodiment. When the worker is performing the cutting operation, the worker can control the cutting operation of the cutter body 22 by stepping on the foot valve 55, which is more convenient to operate.

[0050] Use process: the worker pulls the operating rod 41 outward, passes the corrugated pipe through the limiting hole 33, and adjusts the position of the corrugated pipe according to the cutting length; then slowly releases the operating rod 41, so that the two arc-shaped positioning plates 42 are clamped into the valleys on both sides of the corrugated pipe; the worker can determine whether the arc-shaped positioning plate 42 is clamped into the valley correctly by pulling the corrugated pipe; finally, the cutter body 22 is driven to move towards the first gap 32 and the second gap 43 by stepping on the foot valve 55, and the cutting of the corrugated pipe is completed. When the cutter body 22 moves to the inside of the first gap 32 and the second gap 43, the sensor 6 senses the cutting of the counting rod 23.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.

[0052] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
