[0001] The utility model relates to the technical field of sprocket processing, in particular to an installation and fixing device for a sprocket processed by wire cutting. Background Art

[0002] In the tire manufacturing industry, many process links require the use of transmission devices to achieve material transportation, component transfer and equipment operation. As an important component of the transmission device, the sprocket has the function of transmitting torque, changing speed and rotation direction. It can drive the operation of related equipment efficiently and stably to meet the needs of the tire manufacturing process.

[0003] With the continuous development of tire manufacturing technology, the requirements for the precision and performance of sprockets are getting higher and higher. If the cycle of purchasing a single sprocket is long, and non-standard sprockets are not easy to buy, it is necessary to use wire cutting technology to process the sprocket. In the process of wire cutting sprockets, it is usually necessary to fix the workpiece with a margin on the outer diameter on the workbench bracket, and then wire cut it. During the installation and fixation of the workpiece, it is very easy to have the problem of loose clamping of the workpiece, which will cause the workpiece to fall when the processing is more than halfway, and finally cause inaccurate tooth shape. This will not only affect the processing quality of the sprocket, but also fail to meet the normal use requirements of the sprocket, resulting in material waste, and workers are required to re-process it, which greatly reduces the efficiency of sprocket processing.

Detailed Embodiments

[0026] The following further illustrates the present invention in conjunction with the drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0027] Embodiment 1:

[0028] As Figures 1 to 4As shown in the figure, the utility model provides an installation and fixing device for a wire-cut processed sprocket, which includes a base 2 for fixing the sprocket 1. The base 2 is fixed on the wire-cut cross beam 16 through bolt three 15. A support rod 3 is fixedly installed on the base 2, and a fixing seat 4 is connected to the support rod 3. The fixing seat 4 is cylindrical, and a plurality of slots 5 are circumferentially formed on the fixing seat 4. The vertical cross-section of the slot 5 is rectangular. The support rod 3 is adaptively inserted into the corresponding slot 5 and fixedly connected through bolt two 14. The bolt 14 is inserted from the bottom of the fixing seat 4 and threadedly connected to the support rod 3. A positioning rod 6 is fixedly installed on the fixing seat 4, and a positioning sleeve 7 is sleeved on the positioning rod 6. In actual use, positioning sleeves 2 of different sizes can be made according to different specifications of the sprocket 1, meeting the installation and fixing requirements of sprockets of different specifications. The positioning rod 6 and the positioning sleeve 7 are in damped sliding connection. The sprocket 1 is installed on the positioning sleeve 7, and the center of the sprocket 1 is sleeved on the positioning sleeve 7 and is snap-connected to the positioning sleeve 7. A pressing device 8 for pressing the positioning sleeve 7 and the sprocket 1 is connected to the positioning rod 6.

[0029] Further, the pressing device 8 includes a first pressing plate 81, a first screw rod 82 and a first nut 83. The first screw rod 82 is threadedly connected to the positioning rod 6. The first pressing plate 81 is sleeved on the first screw rod 82 and is fixedly pressed through the first nut 83. During use, first thread the first screw rod 82 onto the positioning rod 6, then sleeve the first pressing plate 81 onto the first screw rod 82, and then tighten the first nut 83 downward, thereby fixing the positions of the positioning sleeve 7 and the sprocket 1. The operation method is simple, enhancing the stability during the wire-cut processing, preventing the sprocket 1 from dropping when the processing is half done, ensuring the accuracy and precision of the processed tooth profile, and meeting the actual use requirements.

[0030] Further, a limiting block 10 is fixedly installed on the side of the positioning sleeve 7. The limiting block 10 is of an L-shaped structure. The limiting block 10 is snap-connected to a limiting groove 11 formed on the sprocket 1. The limiting groove 11 is inserted into the limiting block 10. The limiting block 10 includes a horizontal block 101 and a vertical block 102. The horizontal block 101 and the vertical block 102 are perpendicularly fixedly connected. The horizontal block 101 can limit the up and down position of the sprocket 1. While the vertical block 102 limits the up and down position of the sprocket 1, it can also limit the circumferential rotation of the sprocket 1, thereby better fixing the sprocket 1 on the positioning sleeve 7.

[0031] Further, the cross-section of the slot 5 is cross-shaped, which can adjust the position of the fixing seat 4 at any time according to the needs of sprocket 1 processing. In this way, even if the sprocket 1 coincides with the support rod 3, the part that coincides with the support rod 3 can be processed by adjusting the position of the fixing seat 4, meeting the processing and use requirements of the sprocket and saving raw materials.

[0032] Further, an installation groove 12 is provided on the base 2, and the support rod 3 is installed in the installation groove 12 and fixed by a first bolt 13. Specifically, two first bolts 13 are screwed into the base 2 from one side and pressed against the support rod 3, thereby fixing the position of the support rod 3.

[0033] The working principle of this embodiment is as follows:

[0034] Fix the base 2 on the wire cutting cross beam 16 through a third bolt 15. Then, put one end of the support rod 3 into the installation groove 12 and fix it with a first bolt. Further, insert the other end of the support rod 3 into the corresponding slot 5 on the fixing seat 4 and fix it with a second bolt 14. Then, sleeved the sprocket 1 on the positioning sleeve 7, insert the limiting block 10 on the positioning sleeve 7 into the limiting groove 11 on the sprocket 1, and then insert the positioning sleeve 7 with the sprocket 1 installed on the positioning rod 6. Then, thread the first screw 82 with the positioning rod 6, insert the first pressing plate 81 into the first screw 82, and then use the second nut 85 to press and fix. After the fixing is completed, the wire cutting processing starting point automatically pauses when processing from the left side to the right side of the support rod 3. Then, remove the fixing seat 4 from the support rod 3, rotate it 90 degrees or 180 degrees and then sleeve it on the support rod 3 and lock it, and then process the remaining part that coincides with the support rod 3.

[0035] Embodiment 2:

[0036] As Figure 5 shown, on the basis of Embodiment 1, the present utility model provides a pressing device 8 for an installation and fixing device of a wire cutting processed sprocket, which includes a second pressing plate 84, a second screw 85, a second nut 86 and a fixing block 87. The second pressing plate 84 is sleeved on the second screw 85, the second screw 85 is threadedly connected with the second nut 86, the second nut 86 is located above the second pressing plate 84, and the top of the second screw 85 is fixedly installed with the fixing block 87. The lower part of the second screw 85 is inserted into the positioning rod 6 and threadedly connected with it. When in use, first thread the second nut 86 with the second screw 85, then place the second pressing plate 84 on the top of the positioning sleeve 7 and the sprocket 1, the second screw 85 passes through the second pressing plate 84, and then rotate the fixing block 87 to make the lower part of the second screw 85 threadedly connected with the positioning rod 6, and finally press the second pressing plate 84 against the positioning sleeve 7 and the sprocket 1.

[0037] Further, the second pressing plate 84 includes a first arc plate 841 and a second arc plate 842. The arc of the second arc plate 842 is semi-circular. The first arc plate 841 is integrally connected with the second arc plate 842. The diameter of the first arc plate 841 is the same as the outer diameter of the sprocket 1, and the diameter of the second arc plate 842 is smaller than the distance from the center of the sprocket 1 to its tooth groove 9. In this way, the sprocket 1 to be processed can be exposed outside, and while pressing and fixing the sprocket 1, it does not affect the normal processing of the sprocket 1.
