Description

Technical Field

[0001] This utility model relates to the field of vehicle production technology, and in particular to a rubber strip guide tooling and its rubber strip guide production line. Background Technology

[0002] To ensure continuous operation of the process, the material belt on the tooling needs to be stably and continuously transported to the next process. The tooling, when fully loaded with the material belt, weighs approximately 1.5 tons, and the rubber components are highly susceptible to stretching and deformation. Stretching will cause changes in dimensions, directly affecting the quality of subsequent processes. Therefore, a highly stable guide structure must be used to ensure the continuity and stability of the conveying and avoid fluctuations. For example, patent CN111016240A discloses a zero-degree winding material storage system and method, whose steel wire crown guide device includes a mounting frame, a first lifting mechanism (driving the material I-beam wheel to lift), a first clamping mechanism (driving the material I-beam wheel to translate left and right), and a rotation drive mechanism (driving the material I-beam wheel to rotate and guide). However, this device requires the integration of three major drive mechanisms—lifting, translating, and rotating—resulting in a complex structure and large space occupation. Furthermore, the material I-beam wheel needs to move multiple times, leading to insufficient operational stability. Utility Model Content

[0026] This utility model also provides a rubber strip guide production line, including the rubber strip guide tooling as described above, and a strip conveying device connected to the rubber strip guide tooling. The strip conveying device is used to receive and convey the rubber strip guided by the rubber strip guide tooling.

[0027] In use, the I-shaped wheel with the rubber strip wound around it is pushed to the strip guide station frame. The liftable eccentric locking structures on both sides, driven by the transmission structure, lift the I-shaped wheel into the air until the first eccentric wheel, the second eccentric wheel, and the third eccentric wheel work together to lock the shaft end mating part of the I-shaped wheel. After locking, the operator manually operates the drive handle to insert the rotating shaft of the rotating guide mechanism into the shaft hole of the central shaft of the I-shaped wheel. Then, the rotating motor is turned on, causing the I-shaped wheel to rotate. Based on the rolling contact between the locking surface of the central shaft end mating part and the first eccentric wheel, the second eccentric wheel, and the third eccentric wheel, the continuous output of the strip is achieved, and the strip is conveyed to the next process through the strip conveyor device.

[0028] In this invention, when the output rod of the drive cylinder is pushed forward, it drives the first connecting rod and the second connecting rod group to rotate. The first connecting rod drives the U-shaped rotatable support frame to rotate upward, causing the connecting parts to rise. This locks the shaft end mating part of the I-shaped wheel between the second eccentric wheel and the third eccentric wheel, thereby continuously raising the I-shaped wheel until the top of the shaft end mating part contacts the first eccentric wheel, ultimately locking the I-shaped wheel between the first eccentric wheel, the second eccentric wheel, and the third eccentric wheel.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] (1) This utility model provides a rubber strip guide tool, including an I-shaped wheel for winding the rubber strip, a strip guide station frame for pre-limiting the I-shaped wheel, an eccentric locking mechanism for locking and lifting the I-shaped wheel, a rotary guide mechanism for driving the I-shaped wheel to rotate so that the strip on it is guided open, and a moving drive mechanism for moving the rotary guide mechanism horizontally. It has a simple structure, occupies little space, and has high operational stability.

[0031] (2) In this utility model, by setting the first, second and third limiting arms of the material belt guide station frame, the I-shaped wheel can be pre-limited in the material belt guide station frame, which facilitates the subsequent eccentric locking mechanism to lock the I-shaped wheel.

[0032] (3) In this utility model, the eccentric locking mechanism includes a first eccentric wheel group fixed on the guide frame of the material belt, and a second eccentric wheel group and a third eccentric wheel group set on the contouring connection part. Through the cooperation of the transmission rod assembly and the drive cylinder, the contouring connection part can be raised until the shaft end of the I-shaped wheel is locked between the first eccentric wheel group, the second eccentric wheel group and the third eccentric wheel group. That is, this utility model can simultaneously lift and lock the I-shaped wheel through the eccentric locking mechanism. The structure is simpler and occupies less space. Moreover, the coordinated locking of the three eccentric wheel groups can make the I-shaped wheel more stable when it is driven to rotate by the rotating guide mechanism, and its load-bearing capacity is stronger.

[0033] (4) In this utility model, a moving drive mechanism is provided below the rotary guide mechanism. The two can be slidably connected. When the I-shaped wheel is locked and lifted by the eccentric locking mechanism, the rotary guide mechanism can be moved closer to the material strip guide station frame by manually operating the drive handle, so that the rotating mandrel can be inserted into the shaft hole of the central shaft to realize the connection and power transmission. When the rotary motor is turned on, the rotating mandrel drives the I-shaped wheel to rotate, so that the rubber material strip on it is guided open.

[0034] (5) The central shaft end fitting part of the I-shaped wheel in this utility model is set as a locking surface in the circumferential direction. When the I-shaped wheel rotates under the drive of the rotary motor, the locking surface of the central shaft end fitting part rolls into contact with the three eccentric wheels, which can effectively reduce the friction between the eccentric wheel surface and the central shaft surface and reduce wear.

[0035] (6) In practical use, this utility model only requires manual pushing of the I-shaped wheel into the material belt guide station frame. There is no need to manually move the I-shaped wheel afterward. The operation is simple. The I-shaped wheel is lifted into the air for rotation and guide, which can reduce the friction between the bearing wheel surface of the I-shaped wheel and the ground and extend the service life of the I-shaped wheel.

The shaft end fitting part 14 includes a shaft hole that can be engaged and connected with the rotating spindle 42 of the rotating guide mechanism 4.

[0065] Example 2

[0066] A rubber strip guide tooling, based on Example 1,

[0067] In this embodiment, the structure of the material guide station 2 is as follows: Figure 2 As shown, it consists of an upright frame body 21. Both sides of the frame body 21 are provided with limiting arm groups: each group includes a horizontally extending first limiting arm 22 and a second limiting arm 23, which are located below and above the frame body 21 respectively, and are parallel in the same direction. A third limiting arm 24 is placed horizontally between the two first limiting arms 22. The first limiting arm 22 is longer than the second limiting arm 23, and its outer end is made into a wedge shape to guide the I-shaped wheel 1 to accurately enter the material belt guide station frame 2.

[0068] In this embodiment, the structure of the eccentric locking mechanism 3 is as follows: Figure 4As shown, it includes a fixed eccentric locking structure 31 and a liftable eccentric locking structure 32. Specifically, the fixed eccentric locking structure 31 consists of two fixed eccentric locking wheel sets 311 arranged opposite each other at the ends of the two second limiting arms 23; the liftable eccentric locking structure 32 includes: a U-shaped rotatable support frame 321 set on the frame body 21, two eccentric locking wheel sets 322 set at both ends of the U-shaped rotatable support frame 321 and arranged opposite each other, and a transmission structure 323, wherein the transmission structure 323 includes a transmission rod assembly 3231 and a drive cylinder 3232, used to drive the above-mentioned eccentric locking wheel sets 322 to rise and fall.

[0069] In this embodiment, as Figure 5 As shown, the rotary guide mechanism 4 includes a rotary motor 41 and a rotary spindle 42 disposed at its output end. The shape of the rotary spindle 42 matches the shaft hole of the shaft end fitting part 14 of the I-shaped wheel 1. After insertion, a transmission fit is formed, and the rotary motor 41 drives the I-shaped wheel 1 to rotate via the rotary spindle 42.

[0070] In this embodiment, the moving drive mechanism 5 consists of a base 51, a support 52, and a sliding guide assembly 53: the rotary guide mechanism 4 is fixed on the support 52, and the support 52 is slidably mounted on the base 51 via the sliding guide assembly 53.

[0072] In this embodiment, when the rotary guide mechanism 4 and the moving drive mechanism 5 are actually working, such as Figure 6-7 As shown, after the I-shaped wheel 1 is locked and lifted by the eccentric locking mechanism 3, the operator manually pushes the drive handle 54 forward. The drive handle 54 rotates forward around the pivot, which in turn drives the support seat 52 to slide forward, thereby driving the entire rotary guide mechanism 4 to move forward, so that the rotating spindle 42 can be accurately inserted into the shaft hole of the shaft end fitting part 14 and connected. After the rotary motor 41 is turned on, the rotation of the rotating spindle 42 drives the I-shaped wheel 1 to rotate, thereby guiding the rubber strip on it.

The drive cylinder 3232 is mounted on the frame body 21, and the end of its output rod is connected to the middle of the second rotating shaft 32312.

[0081] In this embodiment, the eccentric locking mechanism 3, when in actual operation, such as Figure 8 As shown, the drive cylinder 3232 is activated, causing the output rod of the drive cylinder 3232 to push forward, pushing the first connecting rod 32314 and the second connecting rod group 32315 to rotate synchronously. The first connecting rod 32314 then drives the U-shaped rotatable support frame 321 to rotate upward, causing the connecting piece 3221 to be lifted as a whole. During the continuous lifting process, the shaft end mating part 14 of the I-shaped wheel 1 is first clamped by the second and third eccentric wheels, and then its top is attached to the first eccentric wheel. Finally, it is locked under the three-point clamping of the first, second and third eccentric wheels, and the entire I-shaped wheel 1 is suspended in the air.
