Description

Technical Field

[0001] The utility model relates to bearing processing, in particular to an upset cylindrical blank conveying mechanism. Background Art

[0002] The inner and outer rings of the bearing are generally processed from cylindrical blanks through heating, upsetting, punching, expanding and sizing. In the upsetting process, a cylindrical blank conveying mechanism is set between the conveyor belt module and the upsetting stamping equipment to convey the cylindrical blank to the vicinity of the stamping equipment, and then the robot completes the loading and unloading. The existing cylindrical blank conveying mechanism generally includes a material guide and a plate chain conveyor belt. The material guide is used to convert the cylindrical blank from a first state with a horizontal axis to a second state with a vertical axis. After the conveyor belt is connected to the cylindrical blank in the second state, it moves and stops after sending the cylindrical blank to the corresponding position. The existing cylindrical blank conveying mechanism still has problems: the cylindrical blank transmission is unstable, and when the conveyor belt stops, it is easy to cause the cylindrical blank to deviate or even tip over, affecting the subsequent material collection of the robot. Utility Model Content

[0003] The present application provides an upset cylindrical blank conveying mechanism, which can solve the problems raised in the background technology.

[0004] In the present application, a roughened cylindrical blank conveying mechanism is provided, comprising:

[0005] The mounting frame has a raised material discharge platform disposed on the top surface close to the first side;

[0006] A material guide portion, fixedly connected to the mounting frame, comprises an inclined section and a vertical section connected to the inclined lower end of the inclined section, and is used to transfer the cylindrical blank from a first state with a horizontal axis to a second state with a vertical axis;

[0007] The material receiving part is located below the material guiding part; it is slidably connected to the mounting frame, and the sliding track passes through the vertical section and the material unloading platform; it includes a slider, a material receiving platform, an elastic member and a clamping mechanism; the slider is used for sliding connection with the mounting frame; the material receiving platform is telescopically arranged on the side of the slider close to the material unloading platform; the elastic member is arranged between the slider and the material receiving platform to keep the material receiving platform in an extended state; the clamping mechanism is arranged on the slider, corresponding to the material receiving platform in an extended state, and can limit or completely release the cylindrical blank in the second state on the material receiving platform;

[0008] The driving mechanism acts on the slide block to drive the material receiving part to move, so that the material receiving platform can abut against the material placing platform and thus retract relative to the slide block.

[0009] Furthermore, the clamping mechanism includes two claws meshed with the shaft position gears and a first cylinder driving one of the claws to rotate.

[0010] Furthermore, an arc-shaped baffle with a swingable upper edge is provided on one side of the straight section close to the unloading platform.

[0011] Furthermore, the driving mechanism is a conveyor belt module or a conveyor chain module.

[0012] In summary, in the present application, a conveying mechanism for upsetting cylindrical blanks includes a mounting frame, a material guide portion, a material receiving portion and a driving mechanism. When the material receiving portion is in a position away from the material discharge platform, the material receiving platform is in an extended state and is directly below the vertical section. The cylindrical blank dropped from the vertical section falls on the material receiving platform, and the clamping mechanism is closed, and the two claws can limit the cylindrical blank. The cylindrical blank follows the material receiving portion to approach the material discharge platform. After the material receiving platform is against the material discharge platform, the slider continues to approach the material discharge platform, causing the material receiving platform to retract. The top surface of the material receiving platform is designed to be flush with or slightly higher than the material discharge platform, so that the cylindrical blank enters the material discharge platform as the material receiving platform retracts. The two claws of the clamping mechanism are completely released, and the material receiving portion is away from the material discharge platform and returns to its original position. The beneficial effects are: the cylindrical blank is more stably transferred to the material discharge platform, which is convenient for subsequent manipulators to pick up materials and improve efficiency.

[0026] See also Figure 1 and Figure 5 A conveying mechanism for upsetting cylindrical blanks comprises a mounting frame 1, a material guiding portion 2, a material receiving portion 3 and a driving mechanism 4.

[0027] A material placing platform 1 a is provided on the top surface of the mounting frame 1 at a position close to the first side thereof, and the material placing platform 1 a is convex relative to the top surface of the mounting frame 1 .

[0028] The material guide part 2 is fixedly connected to the mounting frame 1, and the mounting frame 1 is arranged between the conveyor belt module for conveying cylindrical blanks and the upsetting equipment. The material guide part 2 can be directly fixedly connected to the mounting frame 1, and can also be fixedly connected to the conveyor belt module for conveying cylindrical blanks or the upsetting equipment.

[0029] The material guide part 2 includes an inclined section 2a and a vertical section 2b connected to the inclined lower end of the inclined section 2a. The material guide part 2 is used to transfer the cylindrical blank from the first state with a horizontal axis to the second state with a vertical axis. That is, the cylindrical blank conveying mechanism is arranged between the conveyor belt module for conveying the cylindrical blank and the upsetting equipment. The cylindrical blank on the conveyor belt module is in the first state. The cylindrical blank is conveyed to the inclined upper end of the inclined section 2a of the material guide part 2 through the conveyor belt module. When the cylindrical blank finally falls from the vertical section 2b, it is transferred to the second state.

[0030] The receiving part 3 is located below the material guiding part 2, and is also slidably connected to the mounting frame 1, and the sliding track passes through the vertical section 2b and the material discharging platform 1a. That is, the receiving part 3 is used to receive the cylindrical blanks dropped from the material guiding part 2, and then transfer the cylindrical blanks to the material discharging platform 1a by moving.

[0031] See also Figure 1 and Figure 2 The material receiving part 3 includes a slider 3a, a material receiving platform 3b, an elastic member 3c and a clamping claw mechanism 3d.

[0032] The slider 3a is used for sliding connection with the mounting frame 1. Specifically, two optical axes 1b may be provided on the mounting frame 1, and the slider 3a is fixedly connected to the matching linear bearings on the two optical axes 1b.

[0033] The receiving platform 3b is telescopically arranged on a side of the slider 3a close to the unloading platform 1a. Specifically, a guide rod 3b1 is fixedly connected to the receiving platform 3b, and the guide rod 3b1 is slidably connected to the slider 3a.

[0034] The elastic member 3c is disposed between the slider 3a and the material receiving platform 3b to keep the material receiving platform 3b in an extended state. Specifically, the elastic member 3c can be a spring.

[0035] The clamp mechanism 3d is arranged on the slider 3a, corresponding to the material receiving platform 3b in the extended state. Specifically, the slider 3a is provided with a mounting plate 3a1 on the side close to the material discharging platform 1a, and the clamp mechanism 3d is arranged on the mounting plate 3a1. Accordingly, the material receiving platform 3b can be slidably connected to the mounting plate 3a1, so that the guide rod 3b1 on the material receiving platform 3b can be arranged as one.

[0036] The clamping mechanism 3d can also limit or completely release the cylindrical blank in the second state on the receiving platform 3b.

[0037] See also Figure 5 and Figure 6 Optionally, the clamp mechanism 3d includes two claws 3d1 and a first cylinder 3d2. The two claws 3d1 are rotatably connected to the mounting plate 3a1, and a meshing first gear is arranged at the position of the rotating shaft. The first cylinder 3d2 drives one of the claws 3d1 to rotate. Specifically, a swing arm 3d1a is fixedly connected to the rotating shaft of the claw 3d1, a piston rod of the first cylinder 3d2 is hinged to the swing arm 3d1a, and a cylinder body of the first cylinder 3d2 is hinged to the mounting plate 3a1.

[0038] In this way, when the receiving part 3 is in a position away from the unloading platform 1a, the receiving platform 3b is in an extended state and is directly below the vertical section 2b. The cylindrical blank falling from the vertical section 2b falls on the receiving platform 3b, and the clamping mechanism 3d is closed, and the two claws 3d1 can limit the cylindrical blank (that is, the claws 3d1 can be in contact with the cylindrical blank, or there can be a gap, so that the cylindrical blank can maintain the second state and follow the receiving part 3 to approach the unloading platform 1a). The cylindrical blank follows the receiving part 3 to approach the unloading platform 1a. After the receiving platform 3b abuts against the unloading platform 1a, the slider 3a continues to approach the unloading platform 1a, so that the receiving platform 3b retracts. The top surface of the receiving platform 3b is designed to be flush with or slightly higher than the unloading platform 1a, so that the cylindrical blank enters the unloading platform 1a as the receiving platform 3b retracts. The two claws 3d1 of the clamping mechanism 3d are completely released (ie, when the subsequent material receiving part 3 moves away from the material discharging platform 1a, there will be no interference between the two claws 3d1 and the cylindrical blank), and the material receiving part 3 moves away from the material discharging platform 1a and returns to the original position.

[0039] Optionally, after the cylindrical blank dropped from the vertical section 2b falls on the receiving platform 3b, the top of the cylindrical blank is completely separated from the vertical section 2b. In this way, when the subsequent cylindrical blank follows the receiving portion 3 and approaches the unloading platform 1a, the cylindrical blank will not interfere with the vertical section 2b, but the cylindrical blank will not be stable enough when the two claws 3d1 limit the cylindrical blank.

[0040] See also Figure 3 and Figure 4 Optionally, after the cylindrical stock dropped from the vertical section 2b falls on the receiving platform 3b, the top of the cylindrical stock is still in the vertical section 2b. In this way, when the two claws 3d1 limit the cylindrical stock, the cylindrical stock is initially positioned by the vertical section 2b, which is more stable. However, when the cylindrical stock follows the receiving part 3 to approach the unloading platform 1a, it is necessary to make the top of the cylindrical stock leave the vertical section 2b at the same time. Furthermore, an arc-shaped baffle 2b1 with a swingable upper edge is provided on one side of the vertical section 2b close to the unloading platform 1a. That is, when the cylindrical stock follows the receiving part 3 to approach the unloading platform 1a, under the limitation of the two claws 3d1, the top of the cylindrical stock can push open the arc-shaped baffle 2b1, thereby leaving the vertical section 2b.

[0041] The driving mechanism 4 acts on the slider 3a to drive the material receiving part 3 to move. The stroke of the driving mechanism 4 is set so that the material receiving platform 3b can abut against the material unloading platform 1a and thus retract relative to the slider 3a.

[0042] That is, the driving mechanism 4 can be selected from existing linear motion mechanisms. In view of cost, space and positioning requirements, the driving mechanism 4 is optionally a conveyor belt module or a conveyor chain module.
