Description

Technical Field

[0001] This invention relates to the field of sleeve cutting technology, specifically to an automatic cutting and assembly equipment for multi-specification sleeves of CNC machine tools. Background Technology

[0002] The automatic cutting and assembly equipment for multi-specification sleeves of CNC machine tool wire harnesses is an integrated automated special equipment for CNC machine tool wire harness processing scenarios. It can automatically complete the entire process of cutting sleeves of different specifications to fixed lengths and accurately threading them into the wire harness, replacing traditional manual operation.

[0003] Conventional automatic sleeve cutting and assembly equipment has obvious limitations in adapting to different specifications of sleeves. Most of them can only complete the cutting of sleeves of a single size specification. If it is necessary to switch production specifications, it is necessary to manually replace the corresponding feeding rollers, positioning fixtures and cutting heads. Not only is the adjustment process time-consuming and affects the overall production efficiency of wire harness processing, but it also increases the probability of human error and makes it difficult to meet the needs of multi-variety, small-batch wire harness processing production. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic cutting and assembly equipment for multi-specification sleeves of CNC machine tool wire harnesses, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic cutting and assembly equipment for multi-specification sleeves of CNC machine tool wire harnesses, comprising an equipment frame and a feeding wheel. A cutting component is installed at one end of the equipment frame, and a positioning sleeve is horizontally mounted inside the equipment frame near the cutting component. A positioning component is vertically mounted on the top of the positioning sleeve. Two sets of feeding wheels are symmetrically installed in the middle of the equipment frame, and a guide tube frame is horizontally mounted inside the equipment frame away from the positioning sleeve. The feeding wheel includes an electric guide wheel, an electric telescopic pile, and a docking seat. Electric telescopic piles are connected and installed at both ends of the electric guide wheel, and a docking seat is provided on the top of the electric telescopic pile.

[0006] Furthermore, the equipment frame includes a main frame, a first connecting seat, a support column, a second connecting seat, and a third connecting seat. One end of the main frame is integrally provided with a first connecting seat for installing the cutting component, and the top of the main frame near the cutting component is symmetrically provided with a support column on the left and right sides. The upper end of the support column is horizontally provided with a second connecting seat, and the middle part of the main frame is symmetrically provided with two sets of third connecting seats for installing material conveying wheels.

[0007] Furthermore, the cutting component includes a fixed base, a four-axis robotic arm, and an electrothermal cutter. The fixed base is fixedly installed on the end face of the first connecting base, and the four-axis robotic arm is connected to the side of the fixed base away from the first connecting base. The electrothermal cutter is fixedly installed at the movable end of the four-axis robotic arm.

[0008] Furthermore, the positioning sleeve includes a first support sleeve, a fixed corner bracket, and a positioning through hole. The first support sleeve is horizontally mounted and fixed to the middle of the front end of the main frame through the fixed corner bracket, and the tube body of the first support sleeve has a positioning through hole in the vertical direction for inserting the output end of the positioning component.

[0009] Furthermore, the positioning component includes a support base, an electric telescopic rod, and an anti-slip pad. The electric telescopic rod is vertically fixed through the middle of the support base, and an arc-shaped anti-slip pad is glued and fixed to the bottom output end of the electric telescopic rod.

[0010] Furthermore, the left and right sides of the support base are fixedly installed on the side end face between the two sets of second connecting seats on the left and right sides. The anti-slip pad extends into the positioning through hole, and the bottom arc of the anti-slip pad fits the inner tube wall arc of the first support sleeve. After positioning, it can tightly fit and fix the outer wall of the sleeve with different outer diameters, ensuring that the sleeve will not shift during the cutting process.

[0011] Furthermore, the electric telescopic pile is installed at one end of the third connecting seat via a docking seat, and the electric telescopic pile can adjust the vertical displacement of the electric guide wheel by a built-in electric push cylinder.

[0012] Furthermore, the guide tube frame includes a second support sleeve, a connecting bracket, and a wear-resistant coating. The second support sleeve is horizontally mounted inside the end of the main frame, and the outer wall of the second support sleeve is fixedly connected to the inner wall of the main frame through multiple sets of connecting brackets. Moreover, the inner wall of the second support sleeve is uniformly coated with a wear-resistant coating to reduce the friction of the sleeve conveying. The second support sleeve and the first support sleeve are located on the same horizontal central axis.

[0013] This invention provides an automatic cutting and assembly equipment for multi-specification sleeves of CNC machine tool wire harnesses, which has the following beneficial effects: 1. This invention utilizes two sets of symmetrically mounted feeding wheels at the center of the equipment frame. Firstly, an electric telescopic pile allows adjustment of the distance between the two sets of electric guide wheels according to the outer diameter of the sleeve to be processed. This eliminates the need for manual replacement of different feeding wheel sets, enabling rapid adaptation to feeding insulating sleeves of varying diameters within a certain range. This significantly reduces changeover time and effectively improves the production efficiency of processing multiple sleeve specifications. Secondly, the symmetrically positioned electric guide wheels provide stable clamping and conveying of the sleeve, ensuring stable positioning during transport and preventing slippage or deviation, thus improving the accuracy of subsequent cutting and positioning.

[0014] 2. This invention, by setting a vertically lifting positioning component at the top of the positioning sleeve, allows the electric telescopic rod in the positioning component to push the arc-shaped anti-slip pad at the bottom into the positioning through hole after the sleeve is transported to the preset cutting length. This presses the sleeve firmly against the inner wall of the first supporting sleeve, completing the fixed-length cutting operation in conjunction with the cutting component. The arc-shaped, fitted pressing structure can adapt to the outer wall contour of sleeves with different outer diameters, maintaining a stable pressing force and avoiding the problem of sleeve displacement during the cutting process leading to substandard cutting accuracy, thus improving the pass rate of the cutting operation. Simultaneously, a four-axis robotic arm drives the end-effector to complete the cutting operation. Compared to traditional cold-cutting blades, the cut is smoother and burr-free, effectively preventing burrs from affecting subsequent sleeve insertion operations. Attached Figure Description

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1 to 8As shown, an automatic cutting and assembly device for multi-specification sleeves of CNC machine tool wire harnesses includes a frame 1 and a feeding wheel 5. A cutting component 2 is installed at one end of the frame 1, and a positioning sleeve 3 is horizontally mounted inside the frame 1 near the cutting component 2. A positioning component 4 is vertically mounted on the top of the positioning sleeve 3. Two sets of feeding wheels 5 are symmetrically installed at the top and bottom of the middle of the frame 1, and a guide tube frame 6 is horizontally mounted inside the frame 1 away from the positioning sleeve 3. The feeding wheel 5 includes an electric guide wheel 501 and an electric telescopic wheel 502. The electric telescopic pile 502 and the docking seat 503 are connected to both ends of the electric guide wheel 501. The top of the electric telescopic pile 502 is provided with the docking seat 503. The electric telescopic pile 502 is connected to one end of the third connecting seat 105 through the docking seat 503. The electric telescopic pile 502 can adjust the vertical displacement of the electric guide wheel 501 by pushing it with the built-in electric push cylinder. The equipment frame 1 includes a main frame 101, a first connecting seat 102, a support column 103, a second connecting seat 104 and a third connecting seat 105. The main frame 101 has a first connecting seat 102 integrally provided at one end for mounting the cutting component 2. Support columns 103 are integrally provided symmetrically on the top left and right sides of the end of the main frame 101 near the cutting component 2. A second connecting seat 104 is integrally provided horizontally at the upper end of the support column 103. Two sets of third connecting seats 105 are symmetrically provided vertically on the middle of the main frame 101 for mounting the material conveying wheels 5. The cutting component 2 includes a fixed base 201, a four-axis robotic arm 202, and an electrothermal cutter 203. A fixed base 201 is fixedly installed on the end face of the first connecting base 102, and a four-axis robotic arm 202 is connected to the side of the fixed base 201 away from the first connecting base 102. An electrothermal cutter 203 is fixedly installed at the movable end of the four-axis robotic arm 202. During use, the cutting position and angle of the electrothermal cutter 203 can be flexibly adjusted using the four-axis robotic arm 202. Compared to a fixed cutting structure, this can adapt to the cutting needs of different cutting lengths and specifications of sleeves, meeting diverse processing requirements without adjusting the overall equipment structure. Simultaneously, when the electrothermal cutter 203 completes the cutting, it can simultaneously heat-seal the cut of heat-shrinkable sleeves, preventing fraying and fuzzing at the sleeve ends, further improving the finished quality of the cut sleeves and reducing the workload of subsequent finishing processes. The electric guide wheel 501, utilizing the adaptive spacing adjustment of the electric telescopic pile 502, can automatically adapt to different specifications of sleeves within a certain range, enabling rapid production changeover without disassembly or replacement of parts.

[0019] like Figures 1 to 8As shown, the positioning sleeve 3 includes a first support sleeve 301, a fixing angle seat 302, and a positioning through hole 303. The first support sleeve 301 is horizontally fixed to the middle of the front end of the main frame 101 through the fixing angle seat 302. The tube body of the first support sleeve 301 has a positioning through hole 303 for the insertion of the output end of the positioning component 4 in the vertical direction. The positioning component 4 includes a support base 401, an electric telescopic rod 402, and an anti-slip pad 403. The electric telescopic rod 402 is vertically fixed through the middle of the support base 401, and the bottom output end of the electric telescopic rod 402 is glued and fixed with an arc-shaped anti-slip pad 403. The left and right sides of the support base 401 are fixedly installed on the side end faces between the left and right sets of second connecting seats 104. The anti-slip pad 403 extends into the positioning through hole 303, and the bottom curvature of the anti-slip pad 403 is consistent with that of the first support sleeve 301. The inner wall of the tube 1 is curved to fit the outer wall of the sleeve with different outer diameters after positioning, so that the sleeve will not shift during the cutting process. The guide tube frame 6 includes a second support sleeve 601, a connecting bracket 602 and a wear-resistant coating 603. The second support sleeve 601 is horizontally mounted inside the end of the main frame 101, and the outer wall of the second support sleeve 601 is fixedly connected to the inner wall of the main frame 101 through multiple sets of connecting brackets 602. The inner wall of the second support sleeve 601 is uniformly coated with a wear-resistant coating 603 to reduce the friction of the sleeve conveying. The second support sleeve 601 and the first support sleeve 301 are on the same horizontal central axis. When in use, the coaxial structure can ensure that the sleeve is always conveyed along the preset straight trajectory, avoiding deviation and torsion during the conveying process, and ensuring the positioning accuracy of the subsequent cutting operation. The wear-resistant coating 603 can significantly reduce the friction between the casing and the pipe wall during the conveying process. On the one hand, it can prevent the outer wall of the casing from being scratched by the pipe wall, ensuring that the insulation and protection performance of the casing is not affected by processing. On the other hand, it can also reduce the conveying resistance. Combined with the clamping and conveying of the conveying wheel 5, it can further improve the stability and smoothness of the casing conveying process.

[0020] In summary, as Figures 1 to 8As shown, this CNC machine tool wire harness multi-specification sleeve automatic cutting and assembly equipment first inserts the whole roll of sleeve to be cut through the second support sleeve 601 in the guide tube frame 6, and after being fed out between the upper and lower sets of electric guide wheels 501, it is then inserted into the first support sleeve 301 in the positioning sleeve 3, and the feeding stops after extending to the preset cutting length. After the sleeve to be processed is inserted, the equipment control system controls the electric telescopic piles 502 at the bottom of the upper and lower sets of electric guide wheels 501 to move synchronously according to the input sleeve outer diameter parameters. The electric telescopic piles 502 push the electric guide wheels 501 to move towards the sleeve until the upper and lower sets of electric guide wheels 501 are tightly clamped against the outer wall of the sleeve, completing the automatic adjustment of the feeding distance. The system is adapted to feed sleeves of corresponding specifications. When the sleeve needs to be cut to a fixed length, the electric telescopic rod 402 in the positioning component 4 extends downward and pushes the arc-shaped anti-slip pad 403 at the end to press against the outer wall of the sleeve through the positioning through hole 303, thus firmly fixing the sleeve inside the first support sleeve 301. After the positioning and pressing are completed, the four-axis robotic arm 202 drives the electric heating cutter 203 at the end to move to the preset cutting position. The electric heating cutter 203, after being heated by electricity, completes the cutting operation of the sleeve. At the same time, the heat shrink sleeve cut can be heat-sealed. After the cutting is completed, the electric telescopic rod 402 retracts, the anti-slip pad 403 releases the sleeve, and the electric guide wheel 501 continues to feed the sleeve for the next cutting operation. The entire process can be automated by cutting multiple specifications of sleeves within a certain range without the need for manual disassembly and replacement of feeding and positioning components 4. This significantly shortens changeover and adjustment time, reduces human error rate, and adapts to the needs of CNC machine tool wire harness processing for multiple varieties and small batches.
