Description

Technical Field

[0001] The utility model belongs to the technical field of tire gripping, and particularly relates to a novel jaw device for tire gripping. Background Art

[0002] In the process of tire manufacturing, the forming process of green tires is a key link. A green tire refers to a tire embryo that has not been vulcanized. Its forming process usually involves processing and compounding each processed semi-component through a forming drum on a forming machine to finally form a green tire. The formed green tire needs to pass inspection before entering the vulcanization process for further treatment.

[0003] Currently, the formed green tire needs to be clamped by a jaw device on a forming machine and then unloaded from the forming drum. However, the existing jaw devices on forming machines have some problems in actual applications. First, many jaw devices mainly use lifting cylinders to drive the lifting of the jaws. However, due to the limitation of the lifting height by the lifting cylinders, the clamping device can only clamp green tires of specific specifications and cannot meet the clamping requirements of green tires of multiple specifications. Second, some forming machines are equipped with a lifting mechanism to meet the clamping requirements of green tires of multiple specifications. This kind of lifting mechanism usually realizes the lifting of the jaw device through a hinge rod design, such as a tire unloading device in patent CN219007110U. However, this design may result in uneven clamping force during the lifting process, causing the green tire to be unevenly stressed during clamping. In addition, this kind of lifting mechanism has a complex structure, occupies a large space, has a small application range, and increases the maintenance and operation difficulty of the equipment.

[0004] In summary, the existing jaw devices on forming machines have various problems during the clamping of green tires, mainly including being able to only clamp green tires of specific specifications, uneven clamping force, complex structure, large occupied space, and small application range. These problems limit the wide application of the jaw device and affect the efficiency and quality of the green tire forming process. Therefore, an improved jaw device is needed to solve the problems existing in the prior art and improve the stability and applicability of clamping green tires. Summary of the Utility Model

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be described and explained below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0029] An embodiment of the present utility model provides a new type of tire-gripping jaw device, referring to Figures 1 to 6As shown, the device at least includes a jaw assembly 1, a lifting cylinder 3, and a height adjustment assembly 2. One end of the height adjustment assembly 2 is connected to the jaw assembly 1, and the other end of the height adjustment assembly 2 is connected to the lifting cylinder 3. The height adjustment assembly 2 includes a plurality of sliding rods 201 and sliding seats 202. The sliding rods 201 are connected to the middle jaws 101, and a plurality of pin holes 2011 are arranged at intervals along the vertical direction on the sliding rods 201; a plurality of sliding holes 2021 matching the sliding rods 201 are provided on the sliding seats 202, and a through hole 2022 is provided on one side of the sliding seat 202 close to the sliding holes 2021. The sliding rods 201 slide up and down along the sliding holes 2021 to align the plurality of pin holes 2011 with the through hole 2022 respectively, and the indexing pin 8 is inserted into the through hole 2022 and the pin hole 2011. By designing the height adjustment assembly 2, the height of the jaw assembly 1 can be quickly adjusted in the present utility model, so that green tires of different specifications can be clamped. When it is necessary to clamp green tires of different specifications, after the device is stopped, the indexing pin 8 is pulled out, the sliding rod 201 is slid up or down, and a suitable pin hole 2011 is selected to be aligned with the through hole 2022 on the sliding seat 202. After alignment, the indexing pin 8 is inserted again to achieve precise positioning of the height, thereby completing the setting of the height of the jaw assembly 1. At this time, the normal working state can be entered; the lifting cylinder 3 is provided for small-distance adjustment of the height of the jaw assembly 1 to achieve precise adjustment of the height of the jaw assembly 1. During the clamping process, the lifting cylinder 3 rises to achieve close fitting between the jaw assembly 1 and the green tire. When the green tire is unloaded from the forming drum, the lifting cylinder 3 descends to release the jaw assembly 1, completing one tire unloading operation. The present utility model has the characteristics of being able to clamp green tires of multiple specifications, maintaining a constant clamping force during lifting, having a compact structure, occupying a small space, and having a wide application range.

[0030] Furthermore, the new type of tire-gripping jaw device further includes a guide plate 4, and a plurality of sliders 5 are provided on the guide plate 4; a plurality of guide rails 6 matching the plurality of sliders 5, and the plurality of guide rails 6 are arranged on the sliding seat 202; a fixed seat 7, the fixed seat 7 is connected to the guide plate 4, the lifting cylinder 3 is fixed on the fixed seat 7, and the piston rod of the lifting cylinder 3 passes through the fixed seat 7 and is connected to the sliding seat 202. By setting the sliders 5 and the guide rails 6 in the present utility model, the lifting cylinder 3 drives the entire jaw device to lift more smoothly and precisely during the lifting process, so that the jaw assembly 1 is more stable and accurate when clamping the green tire. The piston rod of the lifting cylinder 3 is connected to the sliding seat 202, and the lifting and lowering of the sliding rod 201 are realized through the telescopic movement of the lifting cylinder 3, thereby driving the height adjustment of the jaw assembly 1.

[0031] Further, an adjustable aperture region 2023 is provided on one side of the sliding hole 2021. Threaded holes 2024 are provided on the left and right sides of the adjustable aperture region 2023. By passing the locking screw 9 through the threaded holes 2024 on the left and right sides of the adjustable aperture region 2023, the locking and loosening of the sliding rod 201 and the sliding seat 202 are achieved. By providing the adjustable aperture region 2023 on one side of the sliding hole 2021, the locking and loosening of the sliding rod 201 and the sliding seat 202 are realized by adjusting the tightness of the locking screw 9. Such a design enables the sliding rod 201 to be adjusted in position according to actual needs. When changing the specifications of the green tire, the locking screw 9 is loosened. At this time, the sliding rod 201 and the sliding seat 202 are loosened, so as to adjust the lifting of the sliding rod 201, making the sliding rod 201 more flexibly drive the jaw assembly 1 to adjust to the position of the green tire to be clamped. When normal operation is required, the locking screw 9 is tightened. At this time, the sliding rod 201 and the sliding seat 202 are locked, and the working state starts. Through the design of the adjustable aperture region 2023, the fixing and adjustment of the sliding rod 201 are more flexible and convenient. The operator can quickly adjust the position of the sliding rod 201 according to different specifications of the green tire, improving the convenience and efficiency of the operation.

[0032] Further, the jaw assembly 1 includes a middle jaw 101, a left swing jaw 102 and a right swing jaw 103 symmetrically arranged at both ends of the middle jaw 101. The left swing jaw 102 and the right swing jaw 103 swing symmetrically around the middle jaw 101. In the present utility model, due to the symmetrically arranged left swing jaw 102 and right swing jaw 103, the force on the swing jaws is uniform when clamping the green tire, avoiding deformation or damage of the green tire caused by unilateral force, resulting in the scrapping of the green tire, and greatly improving the qualified rate of the green tire.

[0033] Further, a plurality of adjustable spikes 104 are provided on the middle jaw 101, and a plurality of adjustable spikes 104 are respectively provided at the ends of the left swing jaw 102 and the right swing jaw 103 far from the middle jaw 101. By designing the adjustable spikes 104, the friction between the adjustable spikes 104 and the green tire can be increased, thereby increasing the clamping force to ensure that the middle jaw 101 can firmly clamp the green tire, preventing the green tire from slipping out during the clamping process, resulting in danger or scrapping of the green tire.

[0034] In some embodiments, the number and arrangement of the adjustable spikes 104 can also be adjusted according to specific requirements. In the present application, a row of adjustable spikes 104 is provided at each of the left and right ends of the middle jaw 101.

[0035] Further, one end of the adjustable spike 104 is provided with a thread. In this embodiment, one end of the adjustable spike 104 is provided with a thread. By rotating the adjustable spike 104, its protruding length can be adjusted to adapt to tires of different sizes. By providing a thread at one end of the adjustable spike 104, the adjustment of the adjustable spike 104 becomes more convenient and precise, enabling it to better adapt to tires of different sizes and improving the versatility and adaptability of this device.

[0036] Further, the jaw assembly 1 further includes a first telescopic cylinder 105 and a second telescopic cylinder 106.

The second telescopic cylinder 106 is provided at the end of the middle jaw 101 away from the first telescopic cylinder 105. The second piston rod 1061 on the second telescopic cylinder 106 is connected to the right swing jaw 103, and the end of the second telescopic cylinder 106 away from the second piston rod 1061 is connected to the left swing jaw 102. In the present utility model, the simultaneous movement of the first piston rod 1051 and the second piston rod 1061 symmetrically drives the swinging of the left swing jaw 102 and the right swing jaw 103 to realize the opening and closing movement of the swing jaws. And due to the symmetrical swinging, the clamping forces of the left swing jaw 102 and the right swing jaw 103 on the green tire are the same, further improving the clamping stability. By providing the first telescopic cylinder 105 and the second telescopic cylinder 106, the automatic opening and closing operation of the swing jaws is realized, improving the automation degree and operation efficiency of the device. And the actions of the left swing jaw 102 and the right swing jaw 103 are more stable and reliable through the cylinder driving method.

[0037] Further, the jaw assembly 1 further includes a first connecting rod 107 and a second connecting rod 108. The first connecting rod 107 is passed through the left swing jaw 102. One end of the first connecting rod 107 is connected to the first piston rod 1051, and the other end of the first connecting rod 107 is connected to the end of the second telescopic cylinder 106 away from the second piston rod 1061.

One end of the second connecting rod 108 is connected to the second piston rod 1061, and the other end of the second connecting rod 108 is connected to the end of the first telescopic cylinder 105 away from the first piston rod 1051. The first connecting rod 107 and the second connecting rod 108 are respectively passed through the left swing jaw 102 and the right swing jaw 103. Through the connection of the first connecting rod 107 and the second connecting rod 108, the linkage of the first telescopic cylinder 105 and the second telescopic cylinder 106 is realized, enabling the left swing jaw 102 and the right swing jaw 103 to swing synchronously, improving the synchronism and coordination of the left swing jaw 102 and the right swing jaw 103, and enabling the jaw assembly 1 to clamp and release the tire more smoothly.

[0038] Further, the left swing claw 102 and the middle claw 101 are rotationally connected through a first rotating shaft 109, and the right swing claw 103 and the middle claw 101 are rotationally connected through a second rotating shaft 110. In the present utility model, the left swing claw 102 and the right swing claw 103 are respectively rotationally connected to the middle claw 101 through the first rotating shaft 109 and the second rotating shaft 110, so that the left swing claw 102 and the right swing claw 103 can swing around the middle claw 101 to realize the opening and closing actions of the claw assembly 1. Through the arrangement of the first rotating shaft 109 and the second rotating shaft 110, the swinging of the left swing claw 102 and the right swing claw 103 is more flexible and stable, improving the clamping ability and operation stability of the claw assembly 1.

[0039] Further, the number of the sliding rods 201 is two. The two sliding rods 201 are symmetrically arranged and connected to the middle claw 101, and the lifting cylinder 3 is arranged between the two sliding rods 201. By the two symmetrically arranged sliding rods 201 and the lifting cylinder 3 at the middle position in the present utility model, the structural stability of the whole device and the accuracy of height adjustment are improved, so that the claw assembly 1 can operate stably during the lifting process and adapt to raw tires of different specifications.

[0040] The working process of the above-mentioned novel tire-gripping claw device is as follows:

[0041] When the specification of the raw tire changes, stop the operation of the novel tire-gripping claw device, pull out the indexing pin 8 and unscrew the locking screw 9, adjust the position of the sliding rod 201 so that the claw assembly 1 is lifted to a position approximately where the raw tire can be clamped. At this time, align the pin hole 2011 with the through hole 2022 and insert the indexing pin 8, and then lock the sliding rod 201 and the sliding seat 202 through the locking screw 9. Start the novel tire-gripping claw device, and through the rising of the piston rod of the lifting cylinder 3, realize the precise control of the height direction of the claw assembly 1, so that the middle claw 101 is closely attached to the bottom of the raw tire, and the adjustable spikes 104 on the middle claw 101 are inserted into the surface of the raw tire. At the same time, control the contraction of the first piston rod 1051 and the second piston rod 1061 so that the left swing claw 102 and the right swing claw 103 are closed simultaneously.

The piston rod of the lifting cylinder 3 descends to separate the middle claw 101 from the bottom of the raw tire. At this time, the raw tire unloaded from the forming drum can be taken off and enter the next process.
