[0002] Internal grinding machine is a machine tool used to process the inner surface of workpieces. It usually includes components such as spindle, grinding head, workpiece clamping device and control system. Internal grinding machine is usually used to process workpieces such as bearing seats, cylinder liners, hydraulic cylinder liners, etc.

[0003] In the existing technology, when the equipment is processing an object, the object may have to wait for a long time in the preparation work due to the high processing speed, so that the object may not be able to keep up with the processing rhythm of the equipment in time. Then, when the object enters the processing equipment, the object cannot maintain a stable posture, which may cause deviations in the processing of parts. These errors may lead to problems such as reduced product quality and production line downtime, increasing production costs and risks, and thus an automatic loading and unloading device for internal cylindrical grinders is needed.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 - Figure 4As shown, the utility model provides a technical solution: an automatic loading and unloading device for an internal cylindrical grinder, comprising: a turning mechanism 1, an auxiliary mechanism 2 is arranged at the bottom of the turning mechanism 1, the turning mechanism 1 comprises a workbench 11, a processing device 12 is arranged on the top of the workbench 11, a cylinder 13 is arranged on the top of the workbench 11, a rack 14 is arranged at one end of the cylinder 13, a rotating rod 16 is arranged on the top of the rack 14, a bearing 18 is arranged on the outer side of one end of the rotating rod 16, a positioning plate 17 is arranged on the outer side of the bearing 18, a fixing plate 19 is arranged on one side of the rotating rod 16, a clamping plate 110 is arranged on one end of the fixing plate 19, a rubber pad 112 is arranged on one side of the clamping plate 110, a cylinder 2 111 is arranged on one side of the clamping plate 110, a guide rail 113 is arranged on the bottom of the processing table, and the working The top of the table 11 is slidably connected to the bottom end of the side plate 15, the top of the side plate 15 is fixedly connected to one side of the rack 14, one side of the rack 14 is fixedly connected to one end of the cylinder 13, the top of the rack 14 is meshedly connected to the outer side of one end of the rotating rod 16, the outer side of one end of the rotating rod 16 is fixedly connected to the inner ring of the bearing 18, the outer ring of the bearing 18 is fixedly connected to the inside of the positioning plate 17, the bottom end of the positioning plate 17 is fixedly connected to the top of the processing table, one side of the rotating rod 16 is fixedly connected to one end of the fixing plate 19, the inside of one end of the fixing plate 19 is fixedly connected to the outer side of the cylinder 2 111, one end of the cylinder 2 111 is fixedly connected to one side of the splint 110, the other side of the splint 110 is fixedly connected to one side of the rubber pad 112, and the bottom of the processing table is fixedly connected to the top of the guide rail 113.

[0026] In this embodiment, when the staff is in use, first, the end of the fixed plate 19 is placed at the edge of the workbench 11, and then the end of the object to be ground is placed between the two clamping plates 110. At this time, the two clamping plates 110 gradually contact the object and clamp the object through the extension of the cylinder 111. The preparation work is completed, and the cylinder 13 is started to retract, so that the rack 14 is moved. As the rack 14 moves, one end of the rotating rod 16 is meshed with it, and the rotating rod 16 is rotated 180 degrees. The rotating rod 16 and the fixing plate 19 are integrated, so they will naturally rotate and flip the object from the edge of the workbench 11 to between the two processing devices 12. Therefore, after the automatic loading, no adjustment is required and the processing can be carried out directly. Since the automatic loading method can ensure the accurate positioning and fixation of the object, the error that may be caused by manual operation is avoided, thereby improving the precision and stability of the processing, and it can be applied to objects of different shapes and sizes, with high adaptability. Similarly, when unloading is required, the unloading can be completed by operating in the opposite way;

[0027] Secondly, the rubber pad 112 designed on the clamp 110 can provide a buffering effect when clamping an object, reducing the impact and vibration between the object and the clamp 110, and the rubber pad 112 has a certain adhesion, which can increase the friction between the clamp 110 and the object, making the clamping more firm and stable, and preventing the object from relative sliding or offsetting during processing.

[0028] Example 2

[0029] like Figure 1 - Figure 4 As shown, the auxiliary mechanism 2 includes a material receiving box 21, one side of the inner wall of the material receiving box 21 is fixedly connected to one end of the spring sheet 23, the top of the spring sheet 23 is fixedly connected to the bottom of the triangular plate 22, one side of the triangular plate 22 is in contact with the inner wall of the material receiving box 21, and the bottom of the material receiving box 21 is slidably connected to the surface of the guide cabinet.

[0030] In this embodiment, the material receiving box 21 is designed to correspond vertically to the position of the fixed plate 19, so that when the fixed plate 19 unloads the material, the material receiving box 21 can collect it in the first time. During the collection process, the interior of the material receiving box 21 is designed with a triangular plate 22. The bevel design of the triangular plate 22 can reduce the stacking height of the material in the material receiving box 21, so that the material can be placed at a smaller angle, which can save space in the material receiving box 21 and facilitate subsequent processing and cleaning. At the same time, the floor of the triangular plate 22 is installed with a spring plate 23, which can reduce the friction between the material and the triangular plate 22, avoid the vibration and impact sound of the material, thereby improving the comfort of the working environment.

[0031] Working principle:

[0032] like Figure 1 - Figure 4 As shown, when the utility model is used, according to the needs of the user, the end of the object to be ground is placed between the two clamping plates 110. At this time, the two clamping plates 110 gradually contact the object and clamp the object through the extension of the cylinder 111. The preparation work is completed, and the cylinder 13 is started to retract, so that the rack 14 is moved. As the rack 14 moves, one end of the rotating rod 16 is meshed with it, and the rotating rod 16 is rotated 180 degrees. The rotating rod 16 and the fixed plate 19 are integrated, and naturally rotated, and the object is turned over from the edge of the workbench 11 to between the two processing equipment 12. After the automatic loading, no adjustment is required, and the processing can be carried out directly. Since the automatic loading method can ensure the accurate positioning and fixation of the object, the error that may be caused by manual operation is avoided;

[0033] The material receiving box 21 is designed to correspond vertically to the position of the fixed plate 19, so that when the fixed plate 19 unloads materials, the material receiving box 21 can collect them at the first time. During the collection process, a triangular plate 22 is designed inside the material receiving box 21. The oblique angle design of the triangular plate 22 can reduce the stacking height of the material in the material receiving box 21, so that the material can be placed at a smaller angle, which can save space in the material receiving box 21.
