Description

Technical Field

[0001] This utility model relates to the field of sunroof flexible shaft technology, and in particular to a sunroof flexible shaft fixed length processing equipment. Background Technology

[0002] A flexible shaft is a shaft with low rigidity, high elasticity, and the ability to bend freely for power transmission. It is used to connect two shafts that are not on the same axis, not in the same direction, or have relative motion to transmit rotational motion and torque. It can flexibly transmit rotational motion and torque to any position. In the production of car sunroofs, flexible shafts need to be installed inside the sunroof; these shafts require cutting during processing.

[0003] However, the sunroof flexible shaft fixed-length processing equipment in the relevant technology still has shortcomings. It is inconvenient to effectively position the sunroof flexible shaft, making it difficult to achieve the purpose of fixed-length cutting each time. It is also inconvenient to accurately adjust the positioning plate according to the cutting length, which reduces the practicality of the device. Furthermore, it is inconvenient to straighten the flexible shaft before cutting, which reduces the cutting accuracy. Therefore, we propose a sunroof flexible shaft fixed-length processing equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing a fixed-length processing device for sunroof flexible shafts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sunroof flexible shaft length-fixed processing device includes a base, a limiting seat and a gantry frame fixedly connected to the top of the base, multiple placement slots on the top of the limiting seat, and a flexible shaft body movably placed in the placement slots. A limiting fixing mechanism is provided on the gantry frame, a cylinder is fixedly connected to the top of the gantry frame, a cutting blade is fixedly connected to the output shaft of the cylinder, a straightening mechanism is provided on the base, a positioning plate is slidably provided on the top of the base, a precision adjustment mechanism is provided between the positioning plate and the base, a pressure sensor is fixedly connected to one side of the positioning plate, a controller is fixedly connected to the front side of the gantry frame, and a cutting groove is provided on the top of the limiting seat.

[0007] As a preferred embodiment of this utility model, the limiting and fixing mechanism includes a horizontal plate fixedly installed on the inner walls of the front and rear sides of the gantry frame, a cylinder two fixedly connected to the top of the horizontal plate, a pressure plate fixedly connected to the output shaft of the cylinder two, and four guide rollers rotatably connected to the inner walls of the front and rear sides of the gantry frame, with multiple flexible shaft bodies respectively moving and abutting against the bottom of the four guide rollers.

[0008] As a preferred embodiment of this utility model, the top of the base is fixedly connected to two support plates, and multiple support rollers are rotatably connected to the inner walls of the front and rear sides of the two support plates, with multiple flexible shaft bodies movably placed on top of the multiple support rollers.

[0009] As a preferred embodiment of this utility model, the precision adjustment mechanism includes two guide rails fixedly connected to the top of the base and two cavities opened in the positioning plate. A lower rack is fixedly connected to the top of the guide rails. Both the guide rails and the lower rack are slidably sleeved in the positioning plate. A compression spring is fixedly connected to the top inner wall of the cavity. An upper rack is fixedly connected to the lower end of the compression spring. A pull rod is fixedly connected to the top of the upper rack. A scale is fixedly connected to the top of the base.

[0010] As a preferred embodiment of this invention, the top ends of the two pull rods are fixedly connected to the same handle.

[0011] In a preferred embodiment of this invention, the two upper racks are slidably sleeved in the corresponding cavities, and the two compression springs are respectively sleeved on the outer side of the corresponding pull rods.

[0012] In a preferred embodiment of this invention, the straightening mechanism includes a drive motor fixedly connected to one side of the base and a groove formed on the top of the base. A threaded rod is fixedly connected to the output shaft of the drive motor, and a drive plate is threadedly fitted onto the outer side of the threaded rod. A clamping plate is fixedly connected to the top of the drive plate, and a fixing opening is formed on one side of the clamping plate. The flexible shaft body is movably placed in the fixing opening. A cylinder is fixedly connected to the top of the clamping plate, and a lifting plate is fixedly connected to the output shaft of the cylinder. Several connecting rods are fixedly connected to the bottom of the lifting plate, and an arc-shaped clamping plate is fixedly connected to the lower end of the multiple connecting rods. The arc-shaped clamping plate movably abuts against the top of the flexible shaft body.

[0013] In a preferred embodiment of this invention, the lifting plate is slidably sleeved within the clamping plate, and the driving plate is slidably sleeved within the groove.

[0014] In this utility model, a sunroof flexible shaft length-fixing processing device is described. To cut the flexible shaft body to the required length, the handle is pulled upwards. The handle causes two pull rods and the upper rack to move upwards without engaging with the lower rack, thus not limiting or fixing the positioning plate. Then, the positioning plate is adjusted laterally along the guide rail and the lower rack by pressing. The position of the positioning plate can be precisely adjusted using a scale. After adjustment, the handle is released. At this time, under the elastic force of two compression springs, the two upper racks move downwards to reset and firmly engage with the lower rack, thus locking the positioning plate.

[0015] In this utility model, a fixed-length processing device for sunroof flexible shafts involves placing multiple flexible shaft bodies on support rollers, passing them between placement grooves and guide rollers, and finally placing one end of each flexible shaft body into a fixed opening. Cylinder three is activated, causing the lifting plate, multiple connecting rods, and multiple arc-shaped clamping plates to move downwards, pressing and fixing the multiple flexible shaft bodies. The drive motor is then activated, causing the threaded rod to rotate. The threaded rod then causes the drive plate and clamping plate to move to the left. The clamping plate can pull the multiple flexible shaft bodies to the left, thus fixing the flexible shaft bodies... Straightening prevents bending and reduced cutting accuracy. When the clamping plate abuts against the pressure sensor on the positioning plate, the pressure sensor sends a signal to the controller. The controller shuts off the drive motor and then starts two cylinders. The two cylinders drive the two pressure plates to move down and press down to fix multiple flexible shaft bodies, preventing displacement and shaking during cutting that would affect the cutting quality. Finally, cylinder one is started, which drives the cutting blade to move down and cut multiple flexible shaft bodies. Multiple flexible shaft bodies can be cut to a fixed length at once, improving cutting efficiency.

[0016] This utility model has a reasonable structural design and can accurately adjust the position of the positioning plate to cut the flexible shaft body into a specified length. Through the positioning of the positioning plate, the length of each batch of flexible shaft bodies is cut to be consistent, thereby achieving the purpose of fixed-length cutting and avoiding the impact of inconsistent lengths on later use. In addition, the flexible shaft body can be straightened before cutting to avoid bending and affecting the cutting accuracy. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A sunroof flexible shaft length-fixed processing device includes a base 1, a limiting seat 6 and a gantry frame 2 fixedly connected to the top of the base 1, a plurality of placement slots 15 opened on the top of the limiting seat 6, a flexible shaft body 7 movably placed in the placement slots 15, a limiting fixing mechanism is provided on the gantry frame 2, a cylinder 12 is fixedly connected to the top of the gantry frame 2, a cutting blade 16 is fixedly connected to the output shaft of the cylinder 12, a straightening mechanism 8 is provided on the base 1, a positioning plate 10 is slidably arranged on the top of the base 1, a precision adjustment mechanism 9 is provided between the positioning plate 10 and the base 1, a pressure sensor 99 is fixedly connected to one side of the positioning plate 10, a controller 11 is fixedly connected to the front side of the gantry frame 2, and a cutting groove 14 is opened on the top of the limiting seat 6.

[0024] Furthermore, the limiting and fixing mechanism includes a horizontal plate 17 fixedly installed on the inner walls of the front and rear sides of the gantry frame 2. A cylinder 18 is fixedly connected to the top of the horizontal plate 17. A pressure plate 13 is fixedly connected to the output shaft of the cylinder 18. Four guide rollers 5 are rotatably connected to the inner walls of the front and rear sides of the gantry frame 2. Multiple flexible shaft bodies 7 are movably abutted against the bottom of the four guide rollers 5. Through the placement groove 15 and the guide rollers 5, the flexible shaft bodies 7 can be guided. The cylinder 18 drives the pressure plate 13 to move down and press down and fix the multiple flexible shaft bodies 7, so as to avoid displacement and shaking during cutting and affect the cutting quality.

[0025] Furthermore, two support plates 3 are fixedly connected to the top of the base 1, and multiple support rollers 4 are rotatably connected to the inner walls of the front and rear sides of the two support plates 3. Multiple flexible shaft bodies 7 are movably placed on the top of the multiple support rollers 4 to facilitate support for the multiple flexible shaft bodies 7.

[0026] Furthermore, refer to Figures 1-4 The precision adjustment mechanism 9 includes two guide rails 92 fixedly connected to the top of the base 1 and two cavities 97 opened in the positioning plate 10. A lower rack 93 is fixedly connected to the top of the guide rails 92. Both the guide rails 92 and the lower rack 93 are slidably sleeved in the positioning plate 10. A compression spring 95 is fixedly connected to the top inner wall of the cavity 97. An upper rack 94 is fixedly connected to the lower end of the compression spring 95. A pull rod 96 is fixedly connected to the top of the upper rack 94. A scale 91 is fixedly connected to the top of the base 1.

[0027] Using the above scheme: cut the flexible shaft body 7 to the required length, pull the handle 98 upwards. The handle 98 drives the two pull rods 96 and the upper rack 94 to move upwards without engaging with the lower rack 93, thus not limiting and fixing the positioning plate 10. Then, squeeze along the guide rail 92 and the lower rack 93 to adjust the positioning plate 10 laterally. The position of the positioning plate 10 can be precisely adjusted by the scale 91. After adjustment, release the handle 98. At this time, under the elastic force of the two compression springs 95, the two upper racks 94 move downwards to reset and firmly engage with the lower rack 93, thus locking the positioning plate 10.

[0028] Furthermore, the top ends of the two levers 96 are fixedly connected to the same handle 98, which facilitates the simultaneous pulling of the two levers 96.

[0029] As a preferred embodiment of this utility model, the two upper racks 94 are slidably sleeved in the corresponding cavities 97, and the two compression springs 95 are respectively sleeved on the outside of the corresponding pull rods 96, so as to facilitate the guidance of the upper racks 94 and the compression springs 95, making their lifting and lowering more stable.

[0030] Furthermore, refer to Figures 1-4 The straightening mechanism 8 includes a drive motor 81 fixedly connected to one side of the base 1 and a groove 82 opened on the top of the base 1. A threaded rod 84 is fixedly connected to the output shaft of the drive motor 81. A drive plate 85 is threadedly sleeved on the outer side of the threaded rod 84. A clamping plate 83 is fixedly connected to the top of the drive plate 85. A fixing opening 80 is opened on one side of the clamping plate 83. The flexible shaft body 7 is movably placed in the fixing opening 80. A cylinder 3 86 is fixedly connected to the top of the clamping plate 83. A lifting plate 87 is fixedly connected to the output shaft of the cylinder 3 86. Several connecting rods 88 are fixedly connected to the bottom of the lifting plate 87. An arc-shaped clamping plate 89 is fixedly connected to the lower end of the multiple connecting rods 88. The arc-shaped clamping plate 89 movably abuts against the top of the flexible shaft body 7.

[0031] Using the above scheme: multiple flexible shaft bodies 7 are placed on the support roller 4 and pass through the placement groove 15 and the guide roller 5. Finally, one end of the flexible shaft body 7 is placed in the fixing port 80. The cylinder 3 86 is started. The cylinder 3 86 drives the lifting plate 87, multiple connecting rods 88 and multiple arc-shaped clamping plates 89 to move down and press down to fix the multiple flexible shaft bodies 7. The drive motor 81 is started. The drive motor 81 drives the threaded rod 84 to rotate. The threaded rod 84 drives the drive plate 85 and the clamping plate 83 to move to the left. The clamping plate 83 can pull the multiple flexible shaft bodies 7 to the left, which can straighten the flexible shaft bodies 7 and avoid bending and reducing the cutting accuracy.

[0032] Furthermore, the lifting plate 87 is slidably sleeved in the clamping plate 83, and the drive plate 85 is slidably sleeved in the groove 82, which facilitates the guidance of the lifting plate 87 and the drive plate 85, making their movement more stable.

[0033] In this utility model, the length of the flexible shaft body 7 is cut according to need. Pulling the handle 98 upward causes the two pull rods 96 and the upper rack 94 to move upward without engaging with the lower rack 93, thus not limiting or fixing the positioning plate 10. Then, the positioning plate 10 is adjusted laterally by pressing along the guide rail 92 and the lower rack 93. The position of the positioning plate 10 can be precisely adjusted by using the scale 91. After adjustment, the handle 98 is released. At this time, under the elastic force of the two compression springs 95, the two upper racks 94 move downward to reset and engage firmly with the lower rack 93, thus locking the positioning plate 10.

[0034] Multiple flexible shaft bodies 7 are placed on the support roller 4 and passed between the placement groove 15 and the guide roller 5. Finally, one end of the flexible shaft body 7 is placed in the fixing port 80. The cylinder 3 86 is activated, which drives the lifting plate 87, multiple connecting rods 88, and multiple arc-shaped clamping plates 89 to move downward and press down to fix the multiple flexible shaft bodies 7. The drive motor 81 is activated, which drives the threaded rod 84 to rotate. The threaded rod 84 drives the drive plate 85 and the clamping plate 83 to move to the left. The clamping plate 83 can pull the multiple flexible shaft bodies 7 to the left, which can straighten the flexible shaft bodies 7 and avoid bending and reducing cutting accuracy. When the clamping plate 83 abuts against the pressure sensor 99 on the positioning plate 10, Pressure sensor 99 sends a signal to controller 11. Controller 11 shuts down drive motor 81 and then starts two cylinders 18. The two cylinders 18 drive the two pressure plates 13 to move downward and press down on and fix multiple flexible shaft bodies 7 to prevent displacement and shaking during cutting, which would affect the cutting quality. Finally, cylinder 12 is started. Cylinder 12 drives the cutting blade 16 to move downward and cut multiple flexible shaft bodies 7. Multiple flexible shaft bodies 7 can be cut to a fixed length at once, improving cutting efficiency. Following the above steps, the second batch can be cut. Because the distance between the positioning plate 10 and the cutting blade 16 is fixed, the length of the first batch and the second batch are the same, thus achieving the purpose of fixed-length cutting.
