[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-3 As shown, the embodiment of the utility model provides a cylinder sleeve rotation alignment device, comprising:

[0024] A cylinder liner positioning plate 1, wherein a plurality of positioning holes 2 are formed on the cylinder liner positioning plate 1;

[0025] A cylinder liner alignment assembly includes a frame 3, the frame 3 includes a support frame 4, a reduction motor 5 is fixed on the support frame 4, an alignment cylinder 6 is connected to the motor shaft 13 of the reduction motor 5, the outer diameter of the alignment cylinder 6 matches the inner diameter of the cylinder liner, a connecting plate 7 is also fixed on the support frame 4, a first distance sensor 8 is installed on the connecting plate 7, and the first distance sensor 8 and the groove 9 on the cylinder liner are in the same horizontal plane.

[0026] The process of the utility model when in use is as follows: first, the cylinder sleeve is grasped by the robot, and after the cylinder sleeve is grasped, it is placed on the alignment cylinder 6 connected to the reduction motor 5 of the frame 3. Since the inner diameter of the alignment cylinder 6 matches that of the cylinder sleeve, the cylinder sleeve can be correctly connected to the alignment cylinder 6. After the cylinder sleeve is connected, the reduction motor 5 is started, and the reduction motor 5 drives the alignment cylinder 6 to rotate. When the alignment cylinder 6 rotates, the cylinder sleeve is detected by the first distance sensor 8. When the cylinder sleeve rotates to the groove 9 thereon corresponding to the first distance sensor 8, the cylinder sleeve stops rotating. At this time, the robot grasps the cylinder sleeve again, puts it into the mold of the casting machine, and finally casts it by the casting machine.

[0027] Furthermore, a mounting plate 10 is fixed on the expenditure frame 4, and the motor shaft 13 of the reduction motor 5 passes through the mounting plate 10, and the connecting plate 7 is fixed on the mounting plate 10. Specifically, the utility model has a mounting plate 10 fixed on the expenditure frame 4 for fixed connection with the connecting plate 7, and there is a gap between the mounting plate 10 and the bottom surface of the alignment cylinder 6 to ensure that the alignment cylinder 6 can rotate smoothly.

[0028] Furthermore, the top of the alignment cylinder 6 has a guide cone 11. The setting of the guide cone 11 at the top of the alignment cylinder 6 enables the cylinder sleeve to be smoothly connected downward from the top of the alignment cylinder 6, plays a role in guiding the direction, and avoids the cylinder sleeve from being offset in the vertical direction.

[0029] Furthermore, a second distance sensor 12 is installed on the connecting plate 7, and the second distance sensor 12 is located directly above the first distance sensor 8. Specifically, the second distance sensor 12 on the connecting plate 7 of the utility model can detect whether the cylinder sleeve is connected to the alignment cylinder 6. After the cylinder sleeve is detected, the information is transmitted to the controller connected with its signal. At the same time, the controller is connected with the reduction motor 5 by signal. The controller sends a signal to the reducer to drive it to rotate. When the first distance sensor 8 detects the groove 9, the reducer stops rotating.

[0030] Furthermore, the alignment cylinder 6 is detachably connected to the motor shaft 13. Specifically, in order to enable the utility model to match more alignment cylinders 6, the alignment cylinder 6 is threadedly connected to the motor shaft 13, so that it can be quickly disassembled and replaced, and can adapt to the casting of cylinder sleeves of different models. Specifically, a threaded cylinder can be fixed inside the alignment cylinder 6, and the threaded cylinder 14 is threadedly connected to the motor shaft.

[0031] Furthermore, the positioning holes 2 are evenly arrayed on the cylinder liner positioning plate 1. Through the even positioning holes 2 on the cylinder liner positioning plate 1, the cylinder liner positioning plate 1 can be fixedly arranged or connected to the moving block of the linear guide rail, so that the cylinder liner can be placed in an orderly manner, which is convenient for the robot to grasp in sequence.

[0032] Further, the support frame 4 is a horizontal support, and the reduction motor 5 is fixed on the horizontal support. Specifically, the support frame of the utility model is a horizontal support, and the reduction motor 5 can be directly fixed below the horizontal support.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
