Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, in particular to a corrugated tube winding device. Background Art

[0002] Wires are the power medium for electrical equipment. The wire handle is a wire bundle consisting of several strands of wires. People often wrap a snake skin tube around the outer surface of the wire handle to fix the multiple strands of scattered wires included in the wire handle together, making it easier to assemble the wire handle with the equipment.

[0003] The snake skin tube is a rubber tube with a through hole in the center. It is cut into rubber strips of equal width by spiral ring cutting. It has a certain elasticity. The rubber strip will automatically return to its original tubular shape when no force is applied. When in use, it needs to be stretched by external force to flatten the snake skin tube that has returned to its original tubular shape. It can be wrapped around the outer surface of any cable handle that is larger than the diameter of the rubber tube to tighten the cable handle.

[0004] Since the thickness of the wire handle varies and it is composed of multiple strands of wire, it is relatively messy. The commonly used wire handles are relatively long (generally more than 3 meters). The two ends of the wire handle are often connected to specific components (the components are usually large in size or have been pre-fixed on specific equipment). Therefore, although the center of the snake skin tube is a through hole, it is not convenient for the wire handle to be directly inserted, so it can only be unfolded into strips and then the wire handle can be wound.

[0005] Currently, in order to wind the snake skin tube on the outer surface of the wire handle, the workers usually use the method of winding it by hand. Figure 1a 、 Figure 1b As shown, when the staff winds the snake skin tube with bare hands, the first person and the second person need to hold the wire respectively to pull the A and B ends (i.e. the left and right ends) of 100 in the same direction (such as Figure 1a The third and fourth persons stand on the C and D sides (i.e., the back and front sides) of the line handle 100 where the snake skin tube is wound. The fourth person holds the spiral snake skin tube 200 (i.e., a hollow spiral roll formed by winding the tube skin, with an overall cylindrical appearance) on the D side of the line handle 100. Figure 1b As shown, the third person is responsible for flattening the corrugated tube 200 for easy winding. On the C side of the handle 100, the third person is responsible for rotating the handle 100 with both hands, following the rotation of the handle 100 and controlling the tube 201 of the corrugated tube 200 to tightly wrap around the outside of the handle 100, thereby gradually wrapping the tube 201 of the corrugated tube 200 around the entire outside of the handle 100. In Figure 1, E1 is the starting point of the handle for coiling the corrugated tube, E2 is the section of the handle where the corrugated tube is wound, E3 is the unfolded section of the corrugated tube, and E4 is the unwound section of the corrugated tube.

[0006] The above manual operation method of winding the snake skin tube is not only time-consuming, labor-intensive, and inefficient, but also requires four people to work together, resulting in high labor costs, which significantly increases the overall winding cost of the snake skin tube on the wire handle.

[0094] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0095] See also Figures 1a to 18 The present invention provides a snake skin tube winding device, comprising a frame 1, a clamping block 2, a screw 3, a pressure rod 4 and a V-shaped stretching block 5;

[0096] The frame 1 includes a double-rod slideway 101 and a U-shaped cavity 102 distributed laterally;

[0097] The double-rod slideway 101 includes two single-rod slideways 9 spaced apart in front and back;

[0098] The left ends of the two single-rod slideways 90 are respectively connected to an annular clamping ring 6;

[0099] The two snap rings 6 are spaced apart from each other and are parallel to each other;

[0100] A snap ring gap 8 is provided between the two snap rings 6;

[0101] The wire handle 100 that needs to be wound around the tube skin 201 extending from the snake skin tube 200 is longitudinally passed through the clamping ring gap 8 and the central through holes of the two clamping rings 6;

[0102] A notch 7 is provided on the lower right side of each snap ring 6;

[0103] The front and rear ends of the block 2 are respectively set in a notch 7;

[0104] Two notches 7 for placing the wire handle 100 into the two clasps 6 so that the wire handle 100 longitudinally passes through the clasp gap 8 and the central through holes of the two clasps 6;

[0105] The clamping block 2 is used to fit into the two notches 7 after the wire handle 100 is placed into the two clamping rings 6;

[0106] The right ends of the two single-rod slideways 90 are connected to the lower left side of the U-shaped cavity 102;

[0107] The left and right sides of the U-shaped cavity 102 are respectively provided with a snake-like pipe outlet and a snake-like pipe inlet;

[0108] A V-shaped stretching block 5 is provided in the inner cavity of the U-shaped cavity 102;

[0109] A longitudinally penetrating pin hole 11 is provided at the upper portions of the front and rear sides of the left end of the U-shaped cavity 102;

[0110] The two pin holes 11 are symmetrically distributed front to back;

[0111] The front and rear ends of the longitudinally distributed pressure rod 4 are respectively fixed in a pin hole 11.

[0112] A finite surface 12 is provided at the bottom of the top plate of the U-shaped cavity 102;

[0113] A wedge-shaped groove 13 is provided on the front and rear sides of the lower portion of the U-shaped cavity 102;

[0114] The two wedge-shaped grooves 13 are symmetrically distributed front to back;

[0115] The right side of each wedge-shaped groove 13 is open, and the inner side of the wedge-shaped groove 13 is connected to the inner cavity of the U-shaped cavity 102;

[0116] The V-shaped stretching block 5 is used to fit a hollow, cylindrical coiled tube 200 and is fixedly placed in the inner cavity of the U-shaped cavity 102 after the fitting is completed;

[0117] It should be noted that if Figure 1b As shown, a snake skin tube 20 is formed by winding a tube skin and is a hollow spiral roll, and the overall appearance is cylindrical.

[0118] When the V-shaped stretching block 5 is fixedly arranged in the inner cavity of the U-shaped cavity 102, the pressure rod 4 is located directly above the left end of the V-shaped stretching block 5, and there is a preset gap between the pressure rod 4 and the top surface of the left end of the V-shaped stretching block 5, see Figure 3 As shown;

[0119] The slit is used to horizontally pass through the tube skin 201 stretched out from the snake skin tube 200 and flatten the tube skin 201 (because the pressure rod 4 and the left end top surface of the V-shaped stretching block 5 squeeze the tube skin 201).

[0120] In the present invention, the specific implementation is as follows: Figure 7 Each single-rod slideway 90 is provided with a longitudinally penetrating threaded through hole 10 at a position directly below each notch 7;

[0121] The two threaded through holes 10 are symmetrically distributed front to back;

[0122] See also Figure 2 、 Figure 9 , the middle part of the card block 2 has a downwardly protruding sliding key 151;

[0123] A circular slot 16 is provided on the front and rear sides of the slide key 15 at positions corresponding to the threaded through hole 10;

[0124] The single-rod slideway 90 is connected to the slide key 15 of the clamping block 2 through a screw 3. The screw 3 passes through the threaded through hole 10 and is in tight contact with the circular clamping groove 16 at the corresponding position.

[0125] In the present invention, the specific implementation is as follows: Figure 8 , a fan-shaped surface 14 is provided on the upper left side of the card block 2;

[0126] The sector surface 14 is used to form a circular (ie, full circle) inner surface together with the inner surface of the snap ring 6 .

[0127] In the present invention, in a specific implementation, the front and rear end surfaces of each sector arc surface 14 are respectively flush with the front and rear end surfaces of the adjacent clamping ring 6 (ie, located on the same vertical plane).

[0128] In the present invention, the specific implementation is as follows: Figure 8 The intersection of the upper end surface of the clamping block 2 and the right side surface of the clamping block 2 is provided with an arc-shaped supporting arc portion 26. Therefore, it can effectively prevent the tube skin of the corrugated tube 200 from being damaged by the sharp corners at the intersection of the upper end surface of the clamping block 2 and the right side surface of the clamping block 2, and reduce the movement resistance encountered by the tube skin of the corrugated tube 200 during rotation.

[0129] In the present invention, the specific implementation is as follows: Figure 9 , the bottom surface of the card block 2, a sliding table 17 is provided on the front and rear sides of the sliding key 15;

[0130] When the front and rear ends of the clamping block 2 are respectively arranged in a notch 7 , the sliding platform 17 is located at the top of the left end of a single-rod slide 90 .

[0131] It should be noted that, in the present invention, a slide key 15 is provided at the lower end of the block 2 , which is slightly smaller than the longitudinal dimension of the double-rod slideway 9 by 1 mm.

[0132] In the present invention, the specific implementation is as follows: Figure 12 , the rear end of the pressure rod 4 is provided with a flat 18;

[0133] The middle part of the pressure rod 4 is provided with a slide rod 1;

[0134] The front end of the pressure rod 4 is provided with a fastening thread 20;

[0135] The front and rear ends of the pressure rod 4 are respectively fixed in a pin hole 11, and the fastening thread 20 at the front end of the pressure rod 4 is threadedly fixedly connected with a nut; therefore, the pressure rod 4 is fastened by the nut.

[0136] In the present invention, the specific implementation is as follows: Figures 14 to 16 , the top of the V-shaped stretching block 5 (specifically the position of the upper end surface in the middle) is provided with a horizontally distributed stretching cylinder 21;

[0137] The outer surface of the stretch cylinder 21 is covered with a snake skin tube 200 from right to left (i.e. a coiled snake skin tube when the tube skin is not unfolded);

[0138] The V-shaped stretching block 5 is directly below the stretching cylinder 21 and is provided with a V-groove 22 in the same direction and parallel to the stretching cylinder 21;

[0139] The horizontal length of the extended cylinder 21 is smaller than the horizontal length of the V-groove 22;

[0140] At the left end of the V-shaped stretching block 5, a longitudinally distributed exhibition stand 25 is vertically arranged;

[0141] The left end of the extension cylinder 21 is connected to the right side of the booth 25;

[0142] See also Figures 16 to 18 As shown, when the V-shaped stretching block 5 is fixedly arranged in the inner cavity of the U-shaped cavity 102, the V-shaped surface 220 at the top of the V-groove 22 on the V-shaped stretching block 5 and the limiting surface 12 at the bottom of the top plate of the U-shaped cavity 102 together form a triangular space (cavity);

[0143] The stretching cylinder 21 on the V-shaped stretching block 5 is located at the center of the triangular space;

[0144] It should be noted that, in the present invention, the limiting surface 12 at the bottom of the top plate of the U-shaped cavity 102 and the V-shaped surface 220 at the top of the V-groove 22 together control the range of motion of the snake skin tube 200 at the inlet, so as to avoid large fluctuations (or changes) in the position of the snake skin tube above the V-groove 22 when the snake skin tube is pulled out to the left, thereby affecting the stretching smoothness of the tube skin and even affecting the inability to stretch the tube skin out of the snake skin tube normally.

[0145] When the V-shaped stretching block 5 is fixedly arranged in the inner cavity of the U-shaped cavity 102, the pressure rod 4 is located directly above the display stand 25 of the V-shaped stretching block 5, and a preset gap is formed between the pressure rod 4 and the top surface of the upper display stand 25 of the V-shaped stretching block 5. The vertical height of the gap is 1 mm greater than the thickness of the skin of the snake skin tube. On the one hand, the snake skin tube can be flattened when it is pulled, and on the other hand, the skin of the snake skin tube will not be broken due to excessive pressure from the pressure rod 4 and the upper display stand 25 on the skin of the snake skin tube due to the gap being too small.

[0146] The slit is used to horizontally pass the tube skin 201 stretched out from the snake skin tube 200 and flatten the tube skin 201 (because the pressure rod 4 and the top surface of the display stand 25 squeeze the tube skin 201).

[0147] In a specific implementation, the thickness of the tube skin 201 of the corrugated tube 200 is 1 mm.

[0148] In a specific implementation, the diameter of the inscribed circle of the triangular space is larger than the outer diameter of the bellows 200, specifically 2 mm larger.

[0149] Specifically, the axial diameter of the stretched cylinder 21 is smaller than the inner diameter of the coiled tube 200 (i.e., the coiled tube when the tube skin is not unfolded). Specifically, the axial diameter of the stretched cylinder 21 is 1 mm smaller than the inner diameter of the coiled tube 200.

[0150] In a specific implementation, the minimum spacing (i.e., the minimum spacing distance) between the V-groove 22 and the extended cylinder 21 is 0.5 mm greater than the wall thickness (i.e., the thickness of the tube skin) of the hollow snake skin tube 200;

[0151] In a specific implementation, the horizontal length of the stretching cylinder 21 is 3 mm shorter than the horizontal length of the V-groove 22;

[0152] In specific implementation, a longitudinally distributed wedge key 23 is provided at the middle position of the front and rear sides of the V-shaped stretching block 5;

[0153] Each wedge key 23 is provided with an inclined surface 24 at the top of the outer end away from the V-shaped stretching block 5;

[0154] See also Figure 2 , two wedge keys 23 are respectively embedded in the left ends of the two wedge-shaped grooves 13.

[0155] In specific implementation, the angle between the inclined surface 24 and the horizontal plane is the same as the angle between the top surface of the wedge-shaped groove 13 and the horizontal plane, that is, they are consistent. Therefore, the inclined surface 24 on the wedge key 23 and the top surface of the wedge-shaped groove 13 can reliably dock.

[0156] In order to more clearly understand the technical solution of the present invention, the specific operation process of the present invention is described below.

[0157] First, see Figure 7 , put the wire handle 100 to be wound around the snake skin tube into the two clamping rings 6 from the notch 7 of the two clamping rings 6 in the starting winding position from right to left;

[0158] It should be noted that the front and rear ends of the cable handle 100 are respectively connected to an electrical device, the size of which is significantly larger than that of the clamping ring 6 . Therefore, the corkscrew cannot be directly inserted into the front and rear ends of the cable handle 100 .

[0159] Then, see Figure 3 , install the clamping block 2 into the two notches 7 and tighten the screws 3 at the front and rear ends of the clamping block 2. In this way, the clamping block 2 is fixed in the clamping ring gap 8, which can prevent the wire handle 100 from falling out of the clamping ring 6 when rotating;

[0160] Then, the hollow, unexpanded cylindrical snake skin tube 200 is put on the outer surface of the stretch cylinder 21 from right to left, and the tube skin of the starting end of the snake skin tube 200 (i.e., the left stretching end) protrudes from the left end root of the stretch cylinder 21 (for example, protruding by 20mm) to facilitate the staff to hold it;

[0161] Then, the V-shaped stretching block 5 equipped with the snake skin tube is installed into the inner cavity of the U-shaped cavity 102 from right to left, and the wedge keys 23 on the front and rear sides of the V-shaped stretching block 5 are respectively inserted into the two wedge-shaped grooves 13 on the U-shaped cavity 102, so that the V-shaped stretching block 5 is firmly clamped. At this time, the V-shaped surface of the V-groove 22 on the V-shaped stretching block 5 and the limiting surface 12 at the bottom of the top plate of the U-shaped cavity 102 together form a triangular space. The stretching cylinder 21 is located at the center of the triangular space. The size of the inscribed circle of this triangular space is slightly larger than the outer diameter of the snake skin tube by 2mm, so that the snake skin tube 200 can be constrained in this triangular space and can only slide along the axial direction of the stretching cylinder 21. When the staff pulls the starting end tube skin of the snake skin tube 200 to the left, the tube skin pulled out of the snake skin tube 200 will be flattened by the stretching cylinder 21;

[0162] It should be noted that, for the present invention, the gap formed between the pressure rod 4 and the booth 25 can keep the stretched tube skin on the snake skin tube 200 flat, pull the starting end tube skin of the snake skin tube 200, so that the flattened snake skin tube skin passes over the supporting arc portion 26 on the upper right side of the block 2 from above, according to Figure 3 The initial end of the snake skin tube is wound in the direction H shown, and is wound around the wire handle 100 between the two clasps 6 for about two turns. The two turns of the snake skin tube skin will firmly wrap the wire handle, thereby generating sufficient friction, so that the snake skin tube skin will not be separated from the wire handle when it is pulled. At this time, only one staff member needs to hold the part of the wire handle 100 to be wound with one hand, and then use the other hand to rotate the device of the present invention with the axis of the wire handle 100 as the center according to the winding direction of the snake skin tube 200 (as shown in FIG. Figure 3 G arrow direction shown), such as Figure 3 As shown, the tube skin 201 of the unwound snake skin tube will be fixed at the starting end, and the unwound snake skin tube will be pulled out as the device of the present invention rotates around the wire handle 100, so that the tube skin of the snake skin tube is continuously pulled out. Through the continuous rotation of the device of the present invention, the work of winding the snake skin tube by one person can be completed;

[0163] It should be noted that, in a specific implementation, the maximum size of the device of the present invention is 70 mm × 30 mm × 30 mm, it is made of aluminum alloy material, the overall weight is less than 100 g, and it is light to use.

[0164] When the winding is completed and the device is dismantled, the two screws 3 are loosened and the clamping block 2 is removed, and the wire handle wound with the snake skin tube can be moved out from the two notches 7. Then, the V-shaped stretching block 5 is pushed to the right in the direction of the opening of the wedge-shaped groove 13, so that the V-shaped stretching block 5 is removed from the U-shaped cavity 102, and the next winding operation can be prepared.

[0165] Compared with the prior art, the snake skin tube winding device provided by the present invention has the following beneficial effects:

[0166] 1. In the present invention, a stretching cylinder with a shaft diameter slightly smaller than the inner diameter of the corrugated tube is inserted into the inner hole of the corrugated tube, so that the tube skin pulled out from the corrugated tube is flattened, thereby avoiding injuries to the hands of workers when stretching the corrugated tube with bare hands;

[0167] 2. In the present invention, the V-shaped surface on the V-groove 22 of the V-shaped stretching block and the limiting surface on the U-shaped cavity 102 together form a triangular space, effectively limiting the movement direction of the coiled tube;

[0168] 3. The present invention adopts a corresponding installation structure in which the wedge key of the V-shaped stretching block and the wedge groove of the frame body are convenient for disassembly and assembly of the V-shaped stretching block;

[0169] 4. In the present invention, the wires are bound together by a clamping ring and a clamping block, which facilitates winding of the corrugated tube.

[0170] To sum up, compared with the existing technology, the present invention provides a corrugated tube winding device with a scientific structural design, which can change the work of winding the corrugated tube on the wire handle from the original four people working together to a single person operating alone, significantly improving the work efficiency of winding the corrugated tube on the wire handle, and has great practical significance.

[0171] In addition, the coiled tube winding device provided by the present invention is easy and quick to operate, and can effectively avoid the problem of inconsistency in the coiled tube winding position and winding density when four people cooperate to wind the coiled tube, and avoid the different coiled tube winding quality due to the different work proficiency of different staff members, significantly improve the coiled tube winding consistency, and ensure the coiled tube winding quality.

[0172] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
