Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile air spring cord laying machine. Background Art

[0002] Automobile air spring suspension shock absorber uses the compressibility of gas to achieve its elastic effect and adapt to the impact caused by different loads and road changes. The stiffness of the airbag directly affects the body stability and driving comfort of the car. The airbag skin, an important component of the airbag, plays a key role. The airbag skin is composed of rubber and an intermediate cord layer. The traditional cord is composed of horizontally and vertically interwoven cords. The important cord layer directly affects the lateral stiffness and vertical stiffness.

[0003] When weaving the airbag skin, an important component of the airbag, the cord needs to be laid. During the laying process, the cords may become entangled with each other, thus affecting the subsequent steps. Therefore, there are certain limitations.

[0004] To this end, we urgently need to provide automotive air spring cord laying machines. Utility Model Content

[0005] The purpose of the utility model is to provide an automobile air spring cord laying machine to solve the problem raised in the above-mentioned background technology that when weaving the airbag skin, an important component of the airbag, the cord needs to be laid, and the cords may be entangled with each other during the laying process, thereby affecting the subsequent links.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile air spring cord laying machine, comprising a base plate and a laying machine, wherein the laying machine is installed on the left side of the upper surface of the base plate, and a positioning device and a laying device are arranged on the right side of the laying machine.

[0007] The positioning device includes a connecting rod, a positioning cylinder, an electromagnetic ring, and a positioning assembly. The connecting rod is fixedly connected to the right side of the wire laying machine, the positioning cylinder is fixedly connected to the right end of the connecting rod, and the electromagnetic ring is installed on the inner wall of the positioning cylinder. The four groups of positioning assemblies are in a ring shape and are respectively installed on the inner walls of the electromagnetic rings.

[0008] A further improvement is that the positioning assembly includes a sleeve, a permanent magnet block, a sliding rod, and a roller, the sleeve being fixedly connected to the inner wall of the electromagnetic ring, the permanent magnet block being slidably connected to the inner wall of the sleeve, the sliding rod being fixedly connected to the center of the outer surface of the permanent magnet block, and the roller being fixedly connected to the outer end of the sliding rod.

[0009] A further improvement is that a through hole with the same diameter as the sliding rod is opened at the center of the outer surface of the sliding sleeve, and the sliding rod is slidably connected to the inside of the through hole. When the silk thread passes through the interior of the positioning cylinder, the electromagnetic ring is energized, thereby generating a repulsive force between the electromagnetic ring and the permanent magnet block, pushing the permanent magnet block to slide outward along the inner wall of the sliding sleeve, thereby pushing the sliding rod and the roller to slide outward, positioning the silk thread, avoiding the silk thread from being entangled with each other, and being able to adapt to silk threads of different diameters, thereby improving the applicability of the device.

[0010] A further improvement is that there are five groups of positioning devices, which are equidistantly installed on the right side of the wire laying machine, so that multiple wires can be laid simultaneously, and the number of positioning devices can be increased according to actual needs to further improve production efficiency.

[0011] A further improvement is that the wire placing device comprises a wire placing unit and two groups of symmetrically arranged tensioning adjustment units.

[0012] The wire laying unit includes a bearing frame, a rotating shaft, a rubber sleeve, and a limiting sleeve. The two bearing frames are respectively fixedly connected to the front and rear sides of the base plate. The rotating shaft is rotatably connected to the inside of the bearing frame. The rubber sleeve is sleeved on the outside of the rotating shaft. Five groups of limiting sleeves are equidistantly fixedly connected to the outer surface of the rubber sleeve. The cord passes through the inside of the limiting sleeve on the rubber sleeve. The friction between the cord and the rubber sleeve drives the rotating shaft to rotate inside the bearing frame, thereby completing orderly wire laying.

[0013] A further improvement is that the tensioning adjustment unit includes a guide sleeve, a connecting slide rod, and a flexible spring. The guide sleeve is fixedly connected to the front end of the right side of the upper surface of the base plate, the connecting slide rod is slidably connected to the inside of the guide sleeve, and the flexible spring is fixedly connected to the top of the guide sleeve and is located outside the connecting slide rod.

[0014] A further improvement is that a group of wire laying units is also fixedly connected to the top of the two groups of tensioning adjustment units, and the top of the connecting slide rod and the flexible spring are connected to the lower surface of the bearing frame. When the cord tension is too tight, it compresses the flexible spring, thereby pushing the connecting slide rod to slide inside the guide sleeve, driving the wire laying unit on the top of the flexible spring to move downward, thereby releasing the excessive tension, and when the cord tension is normal, the flexible spring drives the connecting slide rod to reset and continue normal wiring, thereby completing the adaptive adjustment of the cord tension.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The automotive air spring cord laying machine, when the silk thread passes through the interior of the positioning cylinder, energizes the electromagnetic ring, thereby generating a repulsive force between the electromagnetic ring and the permanent magnet block, pushing the permanent magnet block to slide outward along the inner wall of the sliding sleeve, thereby pushing the sliding rod and the roller to slide outward, positioning the silk thread, avoiding the silk thread from being entangled with each other, and can adapt to silk threads of different diameters, thereby improving the application range of the device.

[0017] 2. When the cord tension is too tight, the automotive air spring cord laying machine compresses the flexible spring, thereby pushing the connecting slide bar to slide inside the guide sleeve, driving the laying unit on the top of the flexible spring to move downward, thereby releasing the excessive tension. When the cord tension is normal, the flexible spring drives the connecting slide bar to reset and continue to lay the cord normally, thereby completing the adaptive adjustment of the cord tension.

The connecting rod 301 is fixedly connected to the right side of the wire laying machine 2, the positioning cylinder 302 is fixedly connected to the right end of the connecting rod 301, the electromagnetic ring 303 is installed on the inner wall of the positioning cylinder 302, and four groups of positioning assemblies 304 are respectively installed on the inner walls of the electromagnetic ring 303 in a ring shape.

[0028] The positioning assembly 304 includes a sleeve 3041, a permanent magnet block 3042, a slide rod 3043, and a roller 3044. The sleeve 3041 is fixedly connected to the inner wall of the electromagnetic ring 303, the permanent magnet block 3042 is slidably connected to the inner wall of the sleeve 3041, the slide rod 3043 is fixedly connected to the center of the outer surface of the permanent magnet block 3042, and the roller 3044 is fixedly connected to the outer end of the slide rod 3043.

[0029] A through hole with the same diameter as the sliding rod 3043 is opened in the center of the outer surface of the sliding sleeve 3041, and the sliding rod 3043 is slidably connected to the inside of the through hole. When the silk thread passes through the interior of the positioning cylinder 302, the electromagnetic ring 303 is energized, thereby generating a repulsive force between the electromagnetic ring 303 and the permanent magnet block 3042, pushing the permanent magnet block 3042 to slide outward along the inner wall of the sliding sleeve 3041, thereby pushing the sliding rod 3043 and the roller 3044 to slide outward, positioning the silk thread and avoiding the silk thread from being entangled with each other. The device can also adapt to silk threads of different diameters, thereby improving the applicability of the device.

[0030] There are five groups of positioning devices, which are equidistantly installed on the right side of the wire laying machine 2. Multiple wires can be laid simultaneously, and the number of positioning devices can be increased according to actual needs to further improve production efficiency.

[0031] The wire placing device comprises a wire placing unit.

[0032] The wire laying unit includes a bearing frame 401, a rotating shaft 402, a rubber sleeve 403, and a limiting sleeve 404. The two bearing frames 401 are respectively fixedly connected to the front and rear sides of the base plate 1, the rotating shaft 402 is rotatably connected to the inside of the bearing frame 401, the rubber sleeve 403 is sleeved on the outside of the rotating shaft 402, and five groups of limiting sleeves 404 are equidistantly fixedly connected to the outer surface of the rubber sleeve 403. The cord passes through the inside of the limiting sleeve 404 on the rubber sleeve 403. The friction between the cord and the rubber sleeve 403 drives the rotating shaft 402 to rotate inside the bearing frame 401, thereby completing orderly wire laying.

[0034] On the basis of Example 1, the wire laying device includes two groups of symmetrically arranged tensioning adjustment units, the tensioning adjustment units include a guide sleeve 405, a connecting slide rod 406, and a flexible spring 407. The guide sleeve 405 is fixedly connected to the front end of the right side of the upper surface of the base plate 1, the connecting slide rod 406 is slidably connected to the inside of the guide sleeve 405, and the flexible spring 407 is fixedly connected to the top of the guide sleeve 405 and is located outside the connecting slide rod 406.

[0035] A group of wire laying units is also fixedly connected to the top of the two groups of tensioning adjustment units. The top of the connecting slide rod 406 and the flexible spring 407 are connected to the lower surface of the bearing frame 401. When the cord tension is too tight, it compresses the flexible spring 407, thereby pushing the connecting slide rod 406 to slide inside the guide sleeve 405, driving the wire laying unit on the top of the flexible spring 407 to move downward, thereby releasing the excessive tension. When the cord tension is normal, the flexible spring 407 drives the connecting slide rod 406 to reset and continue normal routing, thereby completing the adaptive adjustment of the cord tension.
