DETAILED DESCRIPTION

[0022] 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.

[0023] Bearing pressing is a common processing technology in the manufacturing industry, which is used to press the bearing sleeve and the workpiece together. The traditional bearing pressing process usually requires operators to manually load the materials, which has problems such as high labor intensity, low production efficiency, and operation dependence on personnel experience. To solve these problems, automatic loading devices came into being. Automatic loading devices use mechanical, electrical and control technologies to realize automatic loading and unloading of workpieces, improve production efficiency, reduce labor intensity, and make the processing process more stable and reliable.

[0024] Based on the technical defects of the existing technology that the bearing pressing and loading processes are run separately, resulting in reduced production efficiency, please refer to Figure 1-Figure 5The utility model provides an automatic feeding device for bearing pressing processing, which enables bearing pressing and feeding to form a linkage, so as to realize automatic and continuous bearing installation and improve production efficiency. A feeding tray 3 is rotatably connected to the base 1 through the central axis 2. A supporting frame 11 is fixedly arranged on one side of the base 1, and a feeding pipe 4 and a fixing frame 5 are installed on the supporting frame 11. A pressing mechanism 6 for pressing the bearing into the hole of the workpiece is fixedly arranged on the fixing frame 5. A linkage mechanism 7 for driving the feeding tray 3 to rotate intermittently is arranged on one side of the pressing mechanism 6. A batch of bearings are placed in the material pipe, and the workpiece is placed at the bottom of the base 1, and then the pressing mechanism 6 is started to run. When the pressing mechanism 6 is pressed down, the bearing can be smoothly pressed onto the workpiece. When the pressing mechanism 6 is lifted, under the action of the linkage mechanism 7, the feeding tray 3 can be driven to rotate, so that the next bearing is moved to the position of the installation port. This cycle is repeated, and automatic feeding and installation of a batch of bearings can be realized.

[0025] To achieve the linkage operation of bearing pressing and feeding, please refer to Figure 3 The linkage mechanism 7 includes an intermittent component 71 connected to the pressing mechanism 6, a gear 72 is provided on one side of the intermittent component 71 and intermittently meshed with it, the gear 72 is fixedly connected to one end of the rotating shaft 1 73, and a driving wheel 74 is fixedly provided on the other end of the rotating shaft 1 73, and the driving wheel 74 is connected to the driven wheel 75 through a belt, and the driven wheel 75 is fixedly connected to the rotating shaft 2 76, and the rotating shaft 1 73 and the rotating shaft 2 76 are both rotatably connected to one side of the support frame 11 through a bearing frame 78, and a bevel gear 1 77 is fixedly provided at one end of the rotating shaft 2 76, and the bevel gear 1 77 meshes with the bevel gear 2 79, and the bevel gear 2 79 is fixedly connected to the feeding tray 3; when the lifting rod 64 moves downward , the toothed plate 713 in the intermittent component 71 does not mesh with the gear 72, and the feed tray 3 remains stationary at this time. When the lifting rod 64 moves upward, the toothed plate 713 in the intermittent component 71 meshes with the gear 72, and drives the driving wheel 74 to rotate through the rotating shaft 1 73, and the driving wheel 74 drives the driven wheel 75 to rotate through the belt, and the driven wheel 75 drives the bevel gear 1 77 to rotate through the rotating shaft 2 76, and the bevel gear 1 77 drives the bevel gear 2 79 to rotate, thereby rotating the feed tray 3. Since the bearing is in the material hole on the feed tray 3, the feed tray 3 can smoothly move the next bearing to the installation port of the base 1 after the rotation, so as to carry out subsequent installation operations.

[0026] In order to facilitate the distribution and movement of bearings, a plurality of material holes are opened on the feed tray 3, and an installation opening corresponding to the position of one of the material holes is opened on the base 1, and the installation opening is directly below the pressing mechanism 6; the depth of the material hole is set to be consistent with the thickness of the bearing, so that each time a bearing passes through the position of the discharge pipe 4, it can be brought out for subsequent installation.

[0027] To facilitate the installation of batches of bearings, a feed tube 4 is fixed on the support frame 11, and the bottom of the feed tube 4 corresponds to the position of one of the material holes; when the material hole on the feed tray 3 moves to the bottom of the material tube, the lowest bearing inside the material tube just falls into the material hole.

[0028] To facilitate the pressing of the bearing onto the workpiece, please refer to Figure 2 The pressing mechanism 6 includes a motor 61 installed on the top of the fixed frame 5, a turntable 62 is fixedly provided on the output shaft of the motor 61, the edge of the side wall of the turntable 62 is hinged to the top of the lifting rod 64 through a connecting rod 63, a pressure plate 65 is fixedly provided at the bottom end of the lifting rod 64, the lifting rod 64 is sleeved at one end of a guide plate 66, and the guide plate 66 is fixedly connected to the inner side of the fixed frame 5; the motor 61 is used to drive and rotate the turntable 62, the turntable 62 drives the lifting rod 64 to move through the connecting rod 63, the lifting rod 64 drives the pressure plate 65 to move, and the pressure plate 65 is pressed down to press the bearing onto the workpiece through the mounting port.

[0029] To avoid the problem that the feed plate 3 rotates when the bearing is pressed and the material hole and the installation port are misaligned, please refer to Figure 3 The intermittent assembly 71 includes two movable rods 711 that are laterally inserted into the lifting rod 64. A spring 712 is sleeved on the outer wall of the movable rod 711. A tooth plate 713 is fixedly provided at one end of the two movable rods 711. Both side walls of the tooth plate 713 are fixedly provided with a protrusion 714. The protrusion 714 is slidably arranged on a guide block 715. The guide block 715 is fixedly connected to one side of the support frame 11 through a fixed rod 716. When the lifting rod 64 drives the tooth plate 713 to move downward through the movable rod 711, the protrusion 714 and the guide block 715 are fixedly connected to one side of the support frame 11. Under the action of block 715, tooth plate 713 moves to the side away from gear 72, so that tooth plate 713 is out of mesh with gear 72, and thus will not drive feed tray 3 to rotate. When tooth plate 713 moves upward, under the action of protrusion 714 and guide block 715, tooth plate 713 moves to the side close to gear 72, so that tooth plate 713 is in meshing state with gear 72, which can drive feed tray 3 to rotate and complete loading. The setting of spring 712 can provide a reset force for the horizontal movement of tooth plate 713.

[0030] In order to control the switching of the meshing state between the tooth plate 713 and the gear 72, the guide block 715 is made into a quadrilateral structure, and a slope 1 7151 and a slope 2 7152 are provided on the guide block 715, and the inclination angle of the slope 1 7151 is greater than the inclination angle of the slope 2 7152; when the tooth plate 713 moves downward, the protrusion 714 contacts the slope 1 7151, and under the action of the slope 1 7151, the tooth plate 713 moves to the side away from the gear 72; when the tooth plate 713 moves upward, the protrusion 714 contacts the slope 2 7152, and under the action of the slope 2 7152, the tooth plate 713 moves to the side close to the gear 72.

[0031] Through the above embodiments, it can be known that: a batch of bearings are placed in the material tube, the workpiece is placed at the bottom of the base 1, and then the pressing mechanism 6 is started to operate, and the motor 61 is used to drive and rotate the turntable 62, and the turntable 62 drives the lifting rod 64 to move through the connecting rod 63, and the lifting rod 64 drives the pressure plate 65 to move. The pressure plate 65 is pressed down to press the bearing onto the workpiece through the installation port. After the bearing is pressed, the pressure plate 65 is lifted and reset. In this process, when the lifting rod 64 drives the tooth plate 713 to move downward through the movable rod 711, under the action of the protrusion 714 and the guide block 715, the tooth plate 713 moves to the side away from the gear 72, so that the tooth plate 713 is out of mesh with the gear 72, so that it will not drive the feeding tray 3 to rotate, and When tooth plate 713 moves upward, under the action of protrusion 714 and guide block 715, tooth plate 713 moves to the side close to gear 72, so that tooth plate 713 and gear 72 are in meshing state, and driving wheel 74 can be driven to rotate through rotating shaft 1 73, and driving wheel 74 drives driven wheel 75 to rotate through belt, and driven wheel 75 drives bevel gear 1 77 to rotate through rotating shaft 2 76, and bevel gear 1 77 drives bevel gear 2 79 to rotate, so that feed tray 3 rotates. Since the bearing is in the material hole on the feed tray 3, the feed tray 3 can smoothly move the next bearing to the installation port of the base 1 after rotation, so as to carry out subsequent installation operations, and this cycle can be repeated to realize automatic loading and installation of batches of bearings.
