[0032] like Figure 1 As shown, an embodiment of the utility model provides a cylinder production line centering and positioning device, including a first driving device 1 and a second driving device 2 that are arranged relatively.

[0033] The first driving device 1 is provided with a first driving rod 11 that can extend toward the second driving device 2, a first baffle 12 is provided at the end of the first driving rod 11, and a plurality of first cushion blocks 13 are provided on the side of the first baffle 12 away from the first driving rod 11. Figure 2 , Figure 4 As shown, the first baffle plate 12 is provided with a first profiling groove 14 corresponding to the first cushion block 13, and the first cushion block 13 is fixedly arranged in the corresponding first profiling groove 14. The second driving device 2 is provided with a second driving rod 21 that can extend toward the first driving device 1, and a second baffle plate 22 is provided at the end of the second driving rod 21. The side of the second baffle plate 22 away from the second driving rod 21 is provided with a plurality of second cushion blocks 23. Figure 3 , Figure 5 As shown, the second baffle 22 is provided with a second contoured groove 24 corresponding to the second cushion block 23 , and the second cushion block 23 is fixedly disposed in the corresponding second contoured groove 24 .

[0034] The present invention provides a cylinder production line centering and positioning device manufacturing process as follows:

[0035] 1) Determine the size, position and angle of the first cushion block 13 and the second cushion block 23 according to the three-dimensional digital model and on-site measured data;

[0036] 2) After the positions of the first cushion block 13 and the second cushion block 23 are determined, the corresponding first profiling grooves 14 and the second profiling grooves 24 are processed on the first baffle plate 12 and the second baffle plate 22 to prevent the first cushion block 13 and the second cushion block 23 from repeatedly changing (such as the cushion block positions not corresponding, angle offset, etc.) after installation and adjustment;

[0037] 3) After the above 1) and 2) are determined, the first cushion block 13 and the second cushion block 23 can be customized and visualized to facilitate later maintenance and spare parts management.

[0038] like Figure 6As shown, during the actual installation, the first drive device 1 and the second drive device 2 are respectively installed on both sides of the conveyor roller 3 of the cylinder production line, and correspond to the lifting and jacking component 4. When the cylinder is transported from the previous station by the conveyor roller 3 to the top of the lifting and jacking component 4, the cylinder may not be in the center of the conveyor roller 3, and it is impossible to align with the positioning pin of the lifting and jacking component 4. At this time, the first drive device 1 extends the first drive rod 11, uses the first pad 13 on the first baffle 12 to match and connect with the concave portion on one side of the cylinder, and pushes the cylinder toward the second drive device 2; similarly, the second drive device 2 extends the second drive rod 21, uses the second pad 23 on the second baffle 22 to match and connect with the concave portion on the other side of the cylinder, and pushes the cylinder toward the first drive device 1. By setting the extension length of the first drive rod 11 and the second drive rod 21, the cylinder can be positioned to the middle of the conveyor roller 3 (the position corresponding to the lifting and jacking component 4) under the interaction of the first drive rod 11 and the second drive rod 21. Then, the lifting component 4 is lifted to lift the cylinder body. After lifting, the cylinder body cooperates with the upper rotating positioning component 5, so that the cylinder body is positioned and the process of this station is carried out.

[0039] The cylinder production line centering and positioning device provided in this embodiment has a first profiling groove 14 and a second profiling groove 24 respectively provided on the first baffle plate 12 and the second baffle plate 22, and the first pad 13 and the second pad 23 are fixed in the corresponding first profiling groove 14 and the second profiling groove 24, so that the first pad 13 and the second pad 23 can be prevented from loosening and displacement during the operation of the equipment, thereby improving the positioning accuracy of the centering and positioning device. In addition, when the first pad 13 and the second pad 23 need to be replaced, they can be quickly positioned to the correct position, thereby improving the replacement efficiency. Since the positioning accuracy of the centering and positioning device is improved, the stability and reliability of the positioning of the centering and positioning device are improved, and the seat detection alarm of the cylinder body and the lifting and jacking component 4 due to the misalignment of the pin and the pin hole is reduced, the average downtime is reduced by 120 minutes per week, the frequency of failures in production is reduced, the MTBF (mean time between repairs) is improved, and the production efficiency is improved.

[0040] In one embodiment of the present invention, Figure 4 , Figure 5As shown, bolt holes are provided in the first profiling groove 14 and the second profiling groove 24, and the first cushion block 13 is fixedly installed in the first profiling groove 14 by bolts, and the second cushion block 23 is fixedly installed in the second profiling groove 24 by bolts. Through the bolt connection, the first cushion block 13 and the second cushion block 23 can be fixedly connected to the first baffle plate 12 and the second baffle plate 22 in a quickly detachable manner, thereby improving the efficiency of replacing the first cushion block 13 and the second cushion block 23. Preferably, the depth of the first profiling groove 14 and the second profiling groove 24 is 2 mm, which can reduce the difficulty of processing, improve the processing accuracy, and ensure the limiting of the first cushion block 13 and the second cushion block 23.

[0041] In order to improve the stability of the first baffle 12 and the second baffle 22 during movement, and thus improve the positioning accuracy with the recessed portion of the cylinder body, as shown in FIG. Figure 1 As shown, the number of the first driving rod 11 and the second driving rod 21 is two, and they are fixedly connected to the corresponding first baffle 12 and second baffle 22. Further, the first driving device 1 and the second driving device 2 are double-rod cylinders, and the first driving rod 11 and the second driving rod 21 are piston rods of the double-rod cylinders.

[0042] In other embodiments of the present invention, the first driving device 1 and the second driving device 2 may also be electric push rods, and the first driving rod 11 and the second driving rod 21 are push rods of the electric push rods.

[0043] In one embodiment of the present invention, Figure 2 , Figure 3 As shown, the first baffle 12 and the second baffle 22 are rectangular.

[0044] In order to meet the market demand, the number of cylinder machine types has increased, resulting in poor compatibility of existing centering and positioning devices. When the production line is changed, the first pad and the second pad need to be repeatedly adjusted to be compatible with the production change, resulting in a lot of downtime. In order to improve the compatibility of the cylinder production line centering and positioning device of the utility model to adapt to different cylinder shapes, such as cylinders of two models, Figure 2 , Figure 3As shown, the first pad 13 includes a left pad 131 of the first machine model and a left pad 132 of the second machine model, which correspond to the left side recesses of the first machine model cylinder body and the second machine model cylinder body respectively; the second pad 23 includes a right pad 231 of the first machine model and a right pad 232 of the second machine model, which correspond to the right side recesses of the first machine model cylinder body and the second machine model cylinder body respectively. When the cylinder production line involves two cylinder bodies of the first machine model and the second machine model, since the first pad 13 and the second pad 23 have pads corresponding to the first machine model and the second machine model at the same time, it is not necessary to replace and adjust the first pad 13 and the second pad 23, avoiding repeated adjustments of the first pad 13 and the second pad 23 after the model change, reducing the model change time by 150 minutes / time, allowing the equipment to operate continuously without stopping, and improving production efficiency.

[0045] During the production and manufacturing of the cylinder production line centering and positioning device provided in the present embodiment, a three-dimensional model is first established according to the equipment and the workpiece, and the size, position and angle of the first cushion block 13 and the second cushion block 23 are designed. Then, the size, position and angle are corrected according to the on-site measured data, and at the same time, the first profiling groove 14 and the second profiling groove 24 with a depth of 2 mm are processed on the first baffle plate 12 and the second baffle plate 22. According to the size of the cylinder bodies of different models, the position, size and angle of the first cushion block 13 and the second cushion block 23 are matched, and then grouped: the left cushion block 131 of the first model and the right cushion block 231 of the first model are a group for the first model; the left cushion block 132 of the second model and the right cushion block 232 of the second model are a group for the second model.

[0046] In this embodiment, the position and installation angle of each first pad 13 and the second pad 23 are determined in advance, and the compatibility of workpieces of different models is taken into consideration. The compatibility is achieved by pads of different positions and sizes (the left pad 131 of the first model and the right pad 231 of the first model are used for the first model; the left pad 132 of the second model and the right pad 232 of the second model are used for the second model); at the same time, in order to prevent the first pad 13 and the second pad 23 from changing position and shifting angle during use, the first baffle plate 12 and the second baffle plate 22 are provided with contoured grooves corresponding to the position of each first pad 13 and the second pad 23.

[0047] In one embodiment of the utility model, in order to further realize the flexible contact between the first cushion block 13 and the second cushion block 23 and the cylinder body, so that the first cushion block 13 and the second cushion block 23 gradually increase the force applied to the cylinder body to prevent the surface of the cylinder body from being damaged, a first elastic pin is provided in the first profiling groove 14, the first elastic pin can be displaced in the direction of the first driving rod 11, and the first cushion block 13 is fixedly arranged at the end of the first elastic pin; a second elastic pin is provided in the second profiling groove 24, the second elastic pin can be displaced in the direction of the second driving rod 11, and the second cushion block 23 is fixedly arranged at the end of the second elastic pin. The structure of the first elastic pin and the second elastic pin can be: an elastic pin hole is provided in the first profiling groove 14 and the second profiling groove 24, and an elastic member (such as a spring) is provided between the first elastic pin, the second elastic pin and the elastic pin hole, so that the first elastic pin and the second elastic pin normally protrude from the bottom surface of the first profiling groove 14 and the second profiling groove 24, and can be completely retracted into the corresponding elastic pin hole after being subjected to force. In this way, taking the first driving device 1 as an example, when the first driving rod 11 drives the first baffle 12 to move toward the cylinder body, the first cushion block 13 retracts into the first contoured groove 14 with the first elastic pin after contacting the cylinder body. Due to the action of the elastic member, the cylinder body is subjected to the force of the first cushion block 13 from small to large, which plays a buffering role and can prevent the surface of the cylinder body from being damaged. The operation process of the second driving device 2 is similar to that of the first driving device 1 and will not be described in detail. Preferably, in order to maintain the movement direction of the first cushion block 13 and the second cushion block 23, the number of the first elastic pin and the second elastic pin are both two.

[0048] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
