DETAILED DESCRIPTION

[0025] 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.

[0026] like Figures 1 to 4 As shown, a feeding mechanism for a shaft sleeve of an automobile engine comprises a discharge hopper 1, a shaft sleeve 2 and a motor 3. A slideway 11 is arranged at the lower part of the discharge hopper 1, a guide groove 12 is arranged at the middle part of the upper side of the slideway 11, a V-shaped opening 13 is arranged at the connection between the slideway 11 and the guide groove 12, a mounting hole 14 is arranged on one side of the guide groove 12 at the front end penetrating through the discharge hopper 1, and mounting openings 15 are symmetrically arranged on both sides of the outer side of the tail of the guide groove 12; the shaft sleeve 2 comprises a shaft sleeve 1 21, a shaft sleeve 2 22, and a shaft sleeve 3 23 respectively, and the slideway 11 is used for screening shaft sleeves 2 of different specifications; a driving wheel 31 is fixedly connected to one end of the motor 3 close to the discharge hopper 1, and the driving wheel 31 is rotatably connected to the feeding mechanism 4, and a side of the feeding mechanism 4 away from the motor 3 is fixedly connected to the top of the slideway 11, and the feeding mechanism 4 is used for pushing each shaft sleeve 2 into the slideway 11, and a control switch 32 is fixedly connected to one side of the chassis of the motor 3.

[0027] It should be noted that a slide 11 is provided in the discharge hopper 1. When the sleeve 2 passes through the slide 11, it eventually enters a different slide 11 corresponding to it due to its different sizes, thereby realizing the screening of different sleeves 2. In the process of the sleeve 2 entering the slide 11, the motor 3 drives the feeding mechanism 4 installed on the discharge hopper 1 with the help of the belt 5. When the sleeve 2 cannot enter the slide 11 immediately during the falling process, it is fed into the corresponding channel by the feeding mechanism 4, thereby realizing the timely feeding of the sleeve 2 and avoiding the accumulation of the sleeve 2 during the screening process.

[0028] The slide 11 includes a slide 111, a slide 2 112 is arranged above the slide 111 inside the discharge hopper 1, a slide 3 113 is arranged above the slide 2 112, a return groove 114 is arranged between the slide 111 and the slide 2 112, and a return groove 2 115 is arranged between the slide 2 112 and the slide 3 113. The slides of the slide 11 belong to the same side of the V-shaped mouth 13 and are far away from the installation mouth 15, and the bottom of the V-shaped mouth 13 is passivated.

[0029] It should be noted that the channel for the sleeve 2 to enter the upper part of the slide 11 is located on the same side of the V-shaped mouth 13 to adapt to the complex situation of simultaneous production of multiple sleeves 2 when discharging the tempering furnace. The channels in the slide 11 are smooth and can allow each sleeve 2 to pass smoothly. The length of the notch of the return groove 114 is equal to the upper end of the slide 2 112. When the sleeve 1 21 and the sleeve 2 22 in the sleeve 2 enter through the slide 3 113, they can fall back into the slide 2 112 through the return groove 114. The length of the notch of the return groove 2 115 is equal to the upper end of the slide 111. When the sleeve 1 21 in the sleeve 2 enters through the slide 2 112, it can fall back into the slide 1 111 through the return groove 2 115. The return groove 114 and the return groove 2 115 are located at the overlapping part of the channels of the slide 11 at the initial part.

[0030] The sleeve 1 21, the sleeve 2 22 and the sleeve 3 23 correspond to the slideway 1 111, the slideway 2 112 and the slideway 3 113 respectively. The sleeve 2 is a cylindrical shaft-shaped structure. The height of the slideway 11 is higher than the corresponding diameter of the sleeve 2, and the length of the slideway 11 is longer than the corresponding length of the sleeve 2.

[0031] The feeding mechanism 4 includes a mounting shaft 41, a fan blade 42 is fixedly connected to the outer side of the middle part of the mounting shaft 41, and both ends of the fan blade 42 are evenly and symmetrically arranged with fixing blocks 43 along the circumferential direction. A driven wheel 44 is arranged at one end of the feeding mechanism 4, and the mounting shaft 41 is rotatably connected in the mounting hole 14. A return block 16 is arranged on the upper surface of the discharge hopper 1 at the upper front end of the guide groove 12, and a protrusion 17 is arranged on the upper lower surface of the return block 16.

[0032] It should be noted that a rotating base is provided at one end of the mounting hole 14 located inside the discharge hopper 1. The rotating base is used to connect the mounting shaft 41 and provide a rotating function, which is not shown in the figure. When the sleeve 2 is not brought back into the V-shaped mouth 13 of the feeding structure by the fan blade 42 through the slideway 11 once, the fall-back block 16 is used to prevent the outflow. The inner side of the protrusion 17 is higher than the rotating surface of the feeding mechanism 4, and the fall-back block 16 is used to further realize this function. The feeding mechanism 4 is driven by the motor 3 and cooperates with the slideway 11 to realize the timely delivery of each workpiece, which plays a role in preventing accumulation. A belt 5 is rotatably connected between the driving wheel 31 and the driven wheel 44, and the control switch 32 is used to control the opening and closing of the motor 3.

[0033] Both ends of the fan blade 42 are evenly and symmetrically provided with fixing blocks 43 along the circumferential direction. The fixing blocks 43 are fixedly connected to the mounting shaft 41 . A plurality of mounting screws 18 are fixedly connected between the mounting opening 15 and the tempering furnace.

[0034] It should be noted that the connection between the fan blade 42 and the mounting shaft 41 is a detachable connection. During installation, the mounting shaft 41 can be inserted into the guide groove 12 in the discharge hopper 1 through the mounting hole 14, and the fan blade 42 and the mounting shaft 41 are then connected by screws. The mounting screws 18 in the mounting port 15 are used to connect the discharge hopper 1 to the furnace mouth of the tempering furnace. After installation, the upper end of the guide groove 12 is connected to the furnace mouth outlet, and the lower end of the discharge hopper 1 is connected to the conveyor belt of the shaft sleeve 2. By designing the discharge hopper 1 as a detachable structure, it is convenient for the staff to disassemble and assemble the slide mechanism.

[0035] After the discharging hopper 1 is installed, the whole is in a downward tilted shape. The slide openings on the slide 11 are all located on the same side of the upward part of the V-shaped mouth 13. The slide 1 111 is located at the lower part of the V-shaped mouth 13 and is shorter than the slide 3 113. The slide 3 113 is located at the upper part of the V-shaped mouth 13 and is longer than the slide 1 111 and the slide 2 112. The lower outlets of the slide 11 are evenly distributed at the same vertical section.

[0036] It should be noted that the discharge hopper 1 is installed in a downward tilted shape to facilitate the sleeve 2 to roll down by itself due to gravity. When the sleeve 2 enters the V-shaped mouth 13, it enters the slide 11 due to inertia. Since the smaller sleeve 2 can structurally enter the slide 11 corresponding to the larger sleeve 2, such as sleeve one 21 can enter slide two 112 and slide three 113, the slides of the slide 11 are opened in an inverted pyramid structure, and the accurate screening of different sleeves 2 can be achieved by cooperating with the fall-back trough structure.

[0037] The top view of the discharge hopper 1 has a table-shaped structure, the rotation direction of the feeding mechanism 4 is the same as the discharge direction of the sleeve 2, the cross-section of the fan blade 42 is an arc-shaped structure, the maximum distance between the outer side of the feeding mechanism 4 and the V-shaped mouth 13 is wider than the longest diameter workpiece of the sleeve 2, and the minimum distance between the outer side of the feeding mechanism 4 and the V-shaped mouth 13 is smaller than the minimum diameter workpiece of the sleeve 2.

[0038] It should be noted that the table-shaped structure allows the sleeves 2 of the discharge hopper 1 to be separated and released onto the subsequent conveyor belt. The fan blades 42 are in a tangent state when in contact with the sleeves 2. The arc-shaped structure allows the sleeves 2 that fall irregularly to be in a state that is convenient for entry relative to the slide 11, which facilitates the adjustment and transmission of the sleeves 2. The distance setting of the feeding mechanism 4 allows the feeding mechanism 4 to rotate sleeves 2 of all sizes, thereby realizing the rotation of each sleeve 2 in the V-shaped mouth 13, and then each sleeve 2 can enter the slide 11 in time.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
