Description

Technical Field

[0001] The present invention relates to the technical field of rubber crawler production, and particularly relates to a press-fitting device for rubber crawlers and a press-fitting equipment for rubber crawlers. Background Art

[0002] A rubber crawler is a crawler made of rubber and a skeleton plate body. Due to its light weight, low noise, corrosion resistance and other properties, it is widely used in machinery, agricultural equipment and military equipment. In the early production process, rubber blocks were directly vulcanized on the crawler, which required operation at high temperature and was very troublesome to replace. Later, it was changed to replaceable rubber blocks. When processing, the rubber blocks were press-fitted onto the matching plate body, resulting in problems such as low coincidence degree and warping of the rubber blocks, reducing the product qualification rate. In the current situation where production increasingly requires high efficiency, how to achieve rapid production and at the same time improve the product qualification rate is a technical problem to be solved by those skilled in the art. Summary of the Invention

[0003] According to an embodiment of the present invention, in order to solve the above deficiencies of the prior art, a press-fitting device for rubber crawlers is provided, which is used for press-fitting a plate body and a rubber block. The plate body is provided with positioning holes, and it includes a plate body positioning component, a first carrier table, a second carrier table, a track, a pushing and pressing component, and one or more rollers. The plate body positioning component transfers the plate body to be press-fitted to a preset position and fixes the plate body; the first carrier table is movably connected to the plate body positioning component, and the first carrier table supports the plate body to be press-fitted; the second carrier table supports the rubber block to be press-fitted; the track is arranged on one side of the second carrier table and extends along the direction from the first carrier table to the second carrier table; the pushing and pressing component is arranged on the track and can move along the track, and the pushing and pressing component pushes the rubber block to be press-fitted into the plate body; each roller is movably connected to the pushing and pressing component, the rotation axis of each roller is parallel to the surface of the rubber block to be press-fitted, and the side surface of each roller is tangent to the surface of the rubber block to be press-fitted. During the process of the pushing and pressing component moving along the track, each roller is driven to extrude the edge of the rubber block.

[0004] Preferably, a plurality of rollers are arranged in parallel, and the rotation axis of each roller is perpendicular to the track.

[0005] Preferably, each roller is connected to the pushing and pressing component through a pair of adjusting bolts, and the pair of adjusting bolts are respectively arranged at both ends of the rotation axis.

By installing rollers on the pressing component, the rubber block can be extruded while being pushed in. As the rubber block is pushed in, the rollers are driven to roll over all edges of the rubber block, without the need to additionally increase the power source.

[0022] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further elaborate on the present invention.

[0023] First, in conjunction with Figures 1 - 5 A pressing device for a rubber crawler according to an embodiment of the present invention will be described, which is used in the scenario of processing a rubber crawler. In this embodiment, taking the pressing of the plate body 1 and the rubber block 2 together as an example for illustration.

[0024] As Figures 1 - 3 shown, the pressing device for a rubber crawler according to an embodiment of the present invention includes a plate body positioning assembly 3, a first loading platform 4, a second loading platform 5, a track 6, a pushing and pressing assembly 7, and one or more rollers 8.

[0025] Specifically, as Figures 1 - 3As shown, the automated device transports the plate body 1 to the first loading platform 4 for the entire device. The plate body positioning component 3 transfers the plate body 1 to be press-fitted to a preset position and fixes the plate body 1. The first loading platform 4 is movably connected to the plate body positioning component 3. The first loading platform 4 supports the plate body 1 to be press-fitted. When changing the model of the plate body 1 to be processed, the size of the first loading platform 4 also changes accordingly to match the changed model. The second loading platform 5 receives the rubber block 2 transported by the automated device and supports the rubber block 2 to be press-fitted. At this time, the positions of the plate body 1 and the rubber block 2 are relatively determined, improving the coincidence degree of the plate body 1 and the rubber block 2. The track 6 is provided on one side of the second loading platform 5 and extends along the direction from the first loading platform 4 to the second loading platform 5, providing a walking path for the movement of the pushing component 7. The pushing component 7 is provided on the track 6 and can move along the track 6. The pushing component 7 pushes the rubber block 2 to be press-fitted into the plate body 1, realizing the approach of the plate body 1 and the rubber block 2 and gradually pushing the rubber block 2 into the plate body 1. Each roller 8 is movably connected to the pushing component 7. The rotating shaft 81 of each roller 8 is parallel to the surface of the rubber block 2 to be press-fitted, and the side surface of each roller 8 is tangent to the surface of the rubber block 2 to be press-fitted. During the movement of the pushing component 7 along the track 6, each roller 8 just passes over the surface of the rubber block 2. As the rubber block 2 is pushed in, it drives the roller 8 to roll over the rubber block 2 without the need to add an additional power source. As the pushing component 7 squeezes the plate body 1 and the rubber block 2 simultaneously, each roller 8 can cover and squeeze the edge of the rubber block 2, solving the problem of the rubber block 2 warping. The movable connection of the roller 8 can adjust the position at any time, adapt to different models of the rubber block 2, and can achieve press-fitting. Moreover, it can be finely adjusted according to the environment to ensure that the press-fitting does not warp. The structure of this device is simple, the maintenance cost is low, the energy consumption is small, and it does not extend the original processing time, improving the qualified rate of products while ensuring the production efficiency.

[0026] Preferably, as Figures 1 - 3 shown, multiple rollers 8 are arranged in parallel, and the rotating shaft 81 of each roller 8 is perpendicular to the track 6. The utilization rate of the roller 8 during the pushing process is higher than that of oblique pushing.

[0027] Preferably, as Figure 2 、 3 shown, each roller 8 is connected to the pushing component 7 through a pair of adjusting bolts 82. The adjusting bolts 82 have low cost and good adjusting effect. A pair of adjusting bolts 82 are respectively arranged at both ends of the rotating shaft 81, and the height of the roller 8 can be finely adjusted to achieve real-time adjustment.

[0028] Preferably, as Figure 3 shown, a spring 83 is sleeved outside the adjusting bolt 82. During the extrusion process, the surface of the rubber block 2 being extruded is not completely flat. The spring 83 plays a buffering role, extending the service life of the device.

[0029] Preferably, as Figures 1 - 5As shown in the figure, the plate positioning component 3 includes a first driver 31, a second driver, a lifting rod 32, and a positioning pin 33 that cooperates with the positioning hole 11; the positioning pin 33 is movably connected to the first driver 31, and the driver drives the positioning pin 33 to move along the extending direction of the track 6. During the movement, it docks with the positioning hole 11 on the plate body 1 to achieve precise positioning of the plate body 1. The sizes of the positioning holes 11 of different models of the plate body 1 are different, and the positioning pin 33 can be adjusted adaptively, enabling the entire device to process rubber tracks of multiple models; both ends of the lifting rod 32 are respectively connected to the second driver and the first loading platform 4, and the second driver drives the lifting rod 32 to move in a direction perpendicular to the track 6, capable of efficiently adjusting the position and stably receiving the plate body 1 conveyed to the first loading platform 4.

[0030] Preferably, a linear bearing is provided between the second driver and the first loading platform 4 to support the first loading platform 4. The axial direction of the linear bearing is parallel to the moving direction of the lifting rod 32 to ensure that the first loading platform 4 operates in the preset direction.

[0031] Preferably, as Figures 1 - 3 shown, the pressing component 7 includes a third driver, a bracket 71, and a pressing plate 72. The bracket 71 is arranged on the track 6, and the pressing plate 72 is arranged on the bracket 71. The height of the bracket 71 is adapted to the second loading platform 5 to support the pressing plate 72. The third driver drives the pressing plate 72 to move along the extending direction of the track 6, and the pressing plate 72 is perpendicular to the track 6, enabling the rubber block 2 to be evenly stressed along the direction of the track 6 and move forward stably. The first, second, and third drivers can be driving devices such as oil cylinders or linear motors.

[0032] Preferably, it further includes a sensor, which can be an optocoupler sensor. The sensor is used to detect whether the edge of the rubber block 2 is completely pressed into the plate body 1 or there is a certain upward warping. If it is detected that there is a certain warping, the extrusion is performed again to further improve the qualified rate.

[0033] During use, as Figures 1 - 5 shown, an external automation device places the plate body 1 on the first loading platform 4. The plate positioning component 3 transfers the plate body 1 to be press-fitted to a preset position and fixes the plate body 1. After positioning, the rubber block 2 is placed on the second loading platform 5. The pressing component 7 moves along the track 6, and at the same time, each roller 8 presses the surface and edge of the rubber block 2 to push the rubber block 2 to be press-fitted into the plate body 1. After the installation is completed, the pressing component 7 returns to the initial position, and an action process ends. Wait for the pressing of the next group of plate body 1 and rubber block 2, and repeat the above actions to achieve batch processing.

[0034] The above is for reference Figures 1 - 5A press-fitting device for a rubber crawler according to an embodiment of the present invention is described. By positioning the plate body 1, the coincidence degree of the plate body 1 and the rubber block 2 can be improved. By installing a roller 8 on the pushing component 7, the rubber block 2 can be extruded while being pushed in. As the rubber block 2 is pushed in, the roller 8 is driven to roll over all the edges of the rubber block 2 without the need to additionally increase a power source. As the pushing component 7 simultaneously extrudes the plate body 1 and the rubber block 2, the problem of the rubber block 2 warping is solved, the qualified rate of the product is improved, and the structure is simple, the maintenance cost is low, the energy consumption is small, and the originally required processing time is not extended, improving the qualified rate of the product while ensuring the production efficiency. At the same time, the positioning pin 33 and the first driver 31, and the first carrier 4 and the plate body positioning component 3 are all movably connected. According to different models of the plate body 1, the sizes and positions of the positioning holes 11 are different. Different positioning pins 33 and the first carrier 4 can be adaptively replaced to process rubber crawlers of multiple models. The roller 8 and the pushing component 7 are also movably connected. By adjusting the vertical distance between the roller 8 and the second carrier 5 through the adjusting bolt 82, various models of rubber blocks 2 can be adapted for extrusion press-fitting. In addition, when processing rubber crawlers of the same model, the fine adjustment of the roller 8 can also adjust the extrusion pressure during press-fitting. Due to different processing environments caused by different temperatures, humidities, etc., the hardness of the same rubber block 2 will be different, and making fine adaptive adjustments can further improve the qualified rate of product press-fitting.

[0035] Secondly, in combination with Figures 1 - 6 A press-fitting device for a rubber crawler according to an embodiment of the present invention is described, which is used in the scenario of processing rubber crawlers and is widely used especially in actual batch production.

[0036] As Figures 1 - 6 shown, the press-fitting device for a rubber crawler according to an embodiment of the present invention has a housing 9, and the housing 9 surrounds the press-fitting device of the rubber crawler, which can play a protective role.

[0037] Preferably, as Figure 2 、 6 shown, the housing 9 is provided with a window 91, a cylinder 92 and a controller. The controller controls the cylinder 92 to open or close the window 91, and the production situation or daily maintenance can be observed in real time through the window 91.

[0038] During use, operating the control switch can open and close the housing 9 and the window 91. In addition, there is a base, which is more convenient during the moving process and is fixed to the ground to keep the equipment stable.

[0039] The press-fitting device for a rubber crawler according to another embodiment of the present invention adds a housing 9 to protect the press-fitting device, reducing damage during processing and daily maintenance and extending the service life.
