[0031] like Figure 2 As shown, it should be noted that the grinding mechanism 3 includes a grinder, a limiting guide rail for limiting the grinder, and a linear push rod for driving the grinder to move; the linear push rod can push the grinder close to or away from the placement table 4, and then the universal joint on the top of the placement table 4 is grinded by the grinder. The grinder is driven by a motor and grinds through a grinding block. The equipment used by the grinding mechanism 3 are all existing publicly available equipment, so it is not elaborated in detail.

[0032] In this embodiment, the picking component 700 is used to automatically complete the structure of universal joint material picking, material discharge and material storage.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the picking component 700 includes a driving box 701 fixed to the inner side of the grinding box 1, two linear guide rails 702 fixedly installed on the front side of the driving box 701, a moving plate 703 slidably connected between the outer sides of the two linear guide rails 702, an extension plate 704 fixed to the left side of the moving plate 703, a first electric push rod 705 fixedly installed on the front side of the extension plate 704, a second electric push rod 706 fixedly installed on the front side of the moving plate 703, two pneumatic clamping mechanisms 707 respectively fixedly installed at the output ends of the first electric push rod 705 and the second electric push rod 706, two transmission rods 708 rotatably connected to the inner side of the driving box 701 through bearings, a synchronous wheel 709 fixed to the outer side of the transmission rod 708, and a synchronous belt 710 meshingly connected between the outer sides of the two synchronous wheels 709.

[0034] It should be noted that the linear guide 702 includes a linear plate 7021 fixed to the front of the driving box 701, a mounting plate 7022 fixed to the front of the linear plate 7021, and four arc grooves 7023 respectively opened on the top and bottom of the two mounting plates 7022. The left and right sides of the arc grooves 7023 are both open. The back of the movable plate 703 is provided with sliding grooves for the two mounting plates 7022 to be plugged in and slide respectively. The top and bottom of the sliding grooves are fixedly connected with arc blocks plugged into the inner sides of the corresponding arc grooves 7023, so that the movable plate 703 can slide between the outer sides of the two linear guides 702 under the limiting sliding action of the arc blocks.

[0035] In addition, the back of the movable plate 703 is fixedly connected to a connecting block fixedly connected to the front of the synchronous belt 710, and the front of the driving box 701 is provided with a connecting hole for the connecting block to slide, so that the synchronous belt 710 can drive the movable plate 703 to move through the connecting block during the transmission process.

[0036] At the same time, a driving mechanism is fixedly installed on the top of the driving box 701. The driving mechanism can be a servo motor. The output shaft of the driving mechanism passes through the top of the driving box 701 and is fixedly connected to the top of the right transmission rod 708, so that the driving mechanism can drive the right transmission rod 708 to rotate, thereby driving the connecting block to move under the meshing transmission action between the two synchronous wheels 709 and the synchronous belt 710, thereby achieving the effect of linear movement.

[0037] In addition, when the first electric push rod 705 is located at the top of the rightmost universal joint on the inner side of the conveying guide rail 603, the second electric push rod 706 is located directly above the placement table 4. When the first electric push rod 705 is located directly above the placement table 4, the second electric push rod 706 is located above the output guide rail 604, and the universal joint located at the bottom of the second electric push rod 706 can be placed inside the output guide rail 604.

[0038] It should also be noted that the pneumatic clamping mechanism 707 is a structure that uses air pressure to clamp and position the workpiece. It can be vacuum adsorption or air pressure to push the clamping jaws for clamping. Any device that can achieve the clamping and positioning effect can be used.

[0039] In this embodiment, the conveying assembly 600 is a structure for automatically conveying a universal joint.

[0040] like Figure 1 As shown, the conveying assembly 600 includes a linear feeding vibration plate 601 located on the left side of the grinding box 1, a connecting guide rail 602 fixedly installed on the right side of the linear feeding vibration plate 601, a conveying guide rail 603 fixedly installed on the top of the mounting seat 2 and connected to the right side of the connecting guide rail 602, an output guide rail 604 fixedly installed on the top of the mounting seat 2, and two small vibration mechanisms 605 fixedly installed at the bottom of the conveying guide rail 603 and the bottom of the output guide rail 604, respectively.

[0041] It should be noted that the connecting guide rail 602 is connected to the interior of the linear feeding vibration disk 601, and the interior of the connecting guide rail 602 is connected to the interior of the conveying guide rail 603. The inner bottom wall of the conveying guide rail 603 is inclined to the right, and the inner bottom wall of the output guide rail 604 is inclined to the right, and the right end of the output guide rail 604 extends to the top of the collection box 5. The conveying guide rail 603 and the output guide rail 604 are both rectangular boxes with an open top. The linear feeding vibration disk 601 is a device that uses the principle of electromagnetic vibration to realize material transportation. It is a device that uses vibration force to push parts from the vibration disk to the linear track for transportation, so that the linear feeding vibration disk 601 can transport the universal joint to the connecting guide rail 602, and then push it to the inner side of the conveying guide rail 603.

[0042] It should also be noted that the universal joint can be limited by the limiting action of the inner side wall of the conveying guide rail 603, and the universal joint can be blocked by the blocking action of the inner right side wall of the conveying guide rail 603, which is convenient for clamping and removing. Under the action of the output guide rail 604, the polished universal joint can be conveniently transported to the inside of the collection box 5 for storage. The small vibration mechanism 605 can be a small vibration motor, which can assist the universal joint to move on the inner side of the conveying guide rail 603 and the output guide rail 604.

[0043] The working principle of the above embodiment is:

[0044] When the universal joint is being polished, the universal joint workpiece is poured into the interior of the linear feeding vibration plate 601, and the linear feeding vibration plate 601 is started, so that the universal joint workpiece can be conveyed to the inner side of the connecting guide rail 602, and under the push of the rear universal joint, the universal joint workpiece can slide on the inner side of the connecting guide rail 602, so that it can be moved to the interior of the conveying guide rail 603, and under the offset and tilting action of the conveying guide rail 603 and the auxiliary vibration action of the small vibration mechanism 605, the universal joint workpiece can slide to the side close to the placement table 4, and at the same time, due to the restriction of the two inner side walls of the conveying guide rail 603, the universal joint workpiece enters the inner After the side space is limited, the first electric push rod 705 is started, so that the left pneumatic clamping mechanism 707 moves downward and clamps the universal joint workpiece at the bottom. After clamping, the first electric push rod 705 rises up and drives the moving plate 703 to move to the right through the synchronous belt 710, so that the universal joint workpiece moves to the top of the placement table 4, and the clamping limit of the universal joint workpiece is released. The synchronous belt 710 drives the moving plate 703 to move to the left again, so that the right pneumatic clamping mechanism 707 moves to the top of the placement table 4, and the second electric push rod 706 is started, so that the right pneumatic clamping mechanism 707 can move to the outside of the universal joint workpiece on the top of the placement table 4. The universal joint workpiece is clamped and limited, and the left pneumatic clamping mechanism 707 is driven to move downward according to the above principle to clamp another universal joint workpiece inside the conveying guide rail 603, and the grinding mechanism 3 is started, so that the grinding mechanism 3 is close to the placement table 4 and grinds the outer side of the universal joint workpiece placed on the top and clamped and limited. After the grinding is completed, the grinding mechanism 3 is away from the placement table 4, and the second electric push rod 706 drives the right pneumatic clamping mechanism 707 to move upward, and then drives the moving plate 703 to move to the right through the synchronous belt 710, so that the right pneumatic clamping mechanism 707 moves to the top of the output guide rail 604. At this time, the first electric push rod 70 5 will move to the top of the placement table 4, the second electric push rod 706 and the first electric push rod 705 are pushed downward, and the pneumatic clamping mechanism 707 is released, so that the universal joint workpiece clamped by the left pneumatic clamping mechanism 707 is placed on the top of the placement table 4, and the universal joint workpiece clamped by the right pneumatic clamping mechanism 707 is placed on the inner side of the output guide rail 604, and the universal joint workpiece on the inner side of the conveying guide rail 603 slides to the right side under the vibration of the right small vibration mechanism 605, so that it can fall into the inside of the collection box 5 and be stored. By repeating the above operations, the material picking, material placing, discharge and material collection operations of the universal joint workpiece can be automatically completed.

[0045] Compared with the prior art, the universal joint grinding device, through the coordinated use of the grinding mechanism 3 inside the grinding box 1, the picking component 700 and the outer conveying component 600, can perform integrated operations of grinding, taking, releasing and collecting materials on the universal joint, thereby greatly improving the efficiency of grinding, thereby greatly reducing the workload of the staff, and facilitating the efficient performance of the grinding work, making the grinding workflow of the universal joint easy to carry out, and solving the problem that the existing universal joint grinding device requires manual material discharge and material collection operations during the grinding process, resulting in a low overall degree of automation.

[0046] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
