Description

Technical Field

[0001] This utility model relates to the field of rubber product technology, and in particular to an adjustable rubber product clamping fixture. Background Technology

[0002] Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products produced from recycled waste rubber. The output of synthetic rubber has far exceeded that of natural rubber, with styrene-butadiene rubber (SBR) being the most produced.

[0003] The production and inspection of rubber sleeves requires the rubber sleeves to be fitted onto cylinders. However, in the existing technology, the rubber sleeves are usually manually stretched open and fitted onto the cylinders, which is not only inefficient and laborious, but also difficult to stretch open manually when the rubber sleeves are thick. Therefore, we propose a clamp with adjustable rubber product holding fixture. Utility Model Content

[0004] This utility model provides an adjustable rubber product clamping fixture, which solves the above-mentioned technical problems.

[0005] The present invention provides the following solution to the above-mentioned technical problems: an adjustable rubber product clamping fixture, comprising a base plate, a connecting plate mounted on the base plate via a lifting control mechanism, a cross-shaped through groove on the upper surface of the connecting plate, a plurality of equally spaced movable blocks slidably mounted on the inner wall of the through groove, a docking component fixedly mounted on the upper surface of the movable block, a first rack fixedly mounted on the upper surface of the movable block, a connecting rod vertically rotatably mounted on the connecting plate, a first gear fixedly mounted on the upper end of the connecting rod and meshing with the first rack, a second gear fixedly mounted on the lower end of the connecting rod, a gear ring rotatably mounted on the lower surface of the connecting plate and meshing with the second gear, one of the second gears being connected to a movement control mechanism.

[0006] Preferably, the lifting control mechanism includes a first electric push rod that is vertically fixedly installed on the upper surface of the base plate, and the free end of the first electric push rod is fixedly connected to the connecting plate.

[0007] Preferably, the movement control mechanism includes a second electric push rod that is laterally fixedly installed on the lower end face of the connecting plate, and a second rack that meshes with one of the second gears is laterally fixedly installed on the free end of the second electric push rod.

[0008] Preferably, the middle part of the through groove is circular, and a fixing rod is fixedly installed on the upper surface of the base plate below the through groove. The cross-sectional radius of the fixing rod is smaller than the cross-sectional radius of the middle part of the through groove.

[0009] Preferably, the ends of the docking component and the moving block are both right angles, and the upper end of the docking component is smoothly rounded.

[0010] The beneficial effects of this utility model are:

[0011] By setting multiple movable blocks with connecting parts at their ends, the multiple connecting parts are combined to form a small cylinder. The rubber shell is then fitted onto the multiple connecting parts. The second electric push rod is then controlled to indirectly drive the multiple connecting parts to move outward, using the connecting parts to expand the rubber shell. Then, the first electric push rod is used to control the connecting plate and the connecting parts on the connecting plate to move downward, so that the expanded rubber shell is fitted onto the fixed rod. This replaces manual operation, is more efficient, and can expand the rubber shell with higher installation strength. The transmission of components such as the first gear and the first rack is set up, and the movement of all connecting parts is indirectly driven by a second electric push rod, reducing the use of power equipment and lowering economic costs.

[0020] The following is in conjunction with the appendix Figure 1-4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] like Figure 1-4 As shown, this utility model discloses an adjustable rubber product clamping fixture, including a base plate 1. A connecting plate 2 is mounted on the base plate 1 via a lifting control mechanism. A cross-shaped through groove 3 is formed on the upper surface of the connecting plate 2. Multiple equally spaced movable blocks 4 are slidably mounted on the inner wall of the through groove 3. A connecting piece 5 is fixedly mounted on the upper surface of each movable block 4, with both ends of the connecting piece 5 and the movable block 4 at right angles. The upper end of the connecting piece 5 is rounded. A first rack 6 is fixedly mounted on the upper surface of each movable block 4. A connecting rod 7 is vertically rotatably mounted on the connecting plate 2, and a connecting rod 7 is fixedly mounted on its upper end. The first gear 8 meshes with the first rack 6, and the second gear 9 is fixedly installed at the lower end of the connecting rod 7. The gear ring 10 that meshes with the second gear 9 is rotatably installed on the lower end face of the connecting plate 2. One of the second gears 9 is connected to a movement control mechanism. This device sets up multiple movable docking parts 5 to form a small radius cylinder. The rubber shell is put on the docking parts 5, and the second electric push rod 12 indirectly drives the docking parts 5 to move and open the rubber shell. Then it is put on the fixed rod 14, which replaces manual operation, is convenient and quick, and can open the rubber shell with higher strength.

[0022] Specifically, the lifting control mechanism includes a first electric push rod 11 vertically fixedly installed on the upper surface of the base plate 1. The free end of the first electric push rod 11 is fixedly connected to the connecting plate 2. The first electric push rod 11 can drive the connecting plate 2 to move up and down, indirectly driving the spread rubber shell to move down, so that the spread rubber shell can be fitted onto the fixed rod 14. The middle part of the through groove 3 is circular. A fixed rod 14 is fixedly installed on the upper surface of the base plate 1 below the through groove 3. The cross-sectional radius of the fixed rod 14 is smaller than the cross-sectional radius of the middle part of the through groove 3. The specifications of the fixed rod 14 are designed to ensure that the docking parts 5 and the moving block 4 will not collide with the fixed rod 14, so that the rubber shell can be fitted onto the fixed rod 14.

[0023] More specifically, the movement control mechanism includes a second electric push rod 12 that is horizontally fixedly installed on the lower end face of the connecting plate 2. The free end of the second electric push rod 12 is horizontally fixedly installed with a second rack 13 that meshes with one of the second gears 9. The second electric push rod 12 indirectly drives all the docking parts 5 to move outward through the transmission of the second rack 13 and other components, which can open the rubber shell sleeve on the docking parts 5, replacing manual operation, which is convenient and quick.

[0024] Working principle:

[0025] The rubber sleeve is fitted onto the multiple mating parts 5. Then, the second electric push rod 12 is controlled to drive the second rack 13 to move. The second rack 13 drives the second gear 9 that meshes with it to rotate. The second gear 9 drives the other second gears 9 to rotate synchronously through the gear ring 10. The second gear 9 drives the corresponding first gear 8 to rotate through the connecting rod 7. The first rack 8 drives the corresponding first rack 6 to move. The first rack 6 drives the corresponding mating part 5 to move outward through the moving block 4, opening the rubber sleeve. Then, the first electric push rod 11 is controlled to shorten, driving the connecting plate 2 to move downward, so that the rubber sleeve abuts against the upper end of the fixed rod 14. As the connecting plate 2 continues to move downward, the mating part 5 is pulled out from the rubber sleeve, and the rubber sleeve is fitted onto the fixed rod 14.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
