DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1 to Figure 5 As shown, the present embodiment aims to provide a device capable of realizing automated grinding for the grinding process of the automobile chain seat 8, so as to reduce labor intensity, improve work efficiency and avoid the occurrence of occupational diseases. To this end, the polishing and grinding equipment for automobile parts production and processing provided in the present embodiment includes a polishing mechanism 22. The polishing mechanism 22 is a polishing motor and a polishing sand disc. Of course, if polishing is required, the polishing sand disc can be replaced with a polishing cloth.

[0025] Considering that the realization of automated grinding mainly requires the automated movement of the grinding mechanism 22 and the automated turning over of the automobile chain seat 8, for this purpose, in this embodiment, a workbench 1 and a frame 2 arranged at the rear end of the workbench 1 are also provided. The workbench 1 is a rectangular box-type structure as a whole, and the frame 2 is a door-type frame, which is fixedly connected to the workbench 1 to maintain stability. A three-axis drive mechanism 21 is arranged on the frame 2. The three-axis drive mechanism 21 mainly realizes movement in the X-axis, Y-axis and Z-axis directions. In this embodiment, its movement is realized by motor drive. The grinding mechanism 22 is arranged on the Z-axis. In this way, the grinding mechanism 22 is arranged above the workbench 1 through the three-axis drive mechanism 21 to realize flexible movement. In this way, the automated movement of the grinding mechanism 22 is completed.

[0026] In order to realize the automatic turning over of the automobile chain seat 8, an accessory placement seat 3 and a rotating lifting mechanism 5 arranged on one side of the accessory placement seat 3 are arranged on the workbench 1. The main purpose of the accessory placement seat 3 is to increase the placement height of the automobile chain seat 8 to facilitate the taking of the rotating lifting mechanism 5. The rotating lifting mechanism 5 includes a driving seat 51 and a ball spline screw 52 that is rotatably lifted and lowered in the driving seat 51. Two motors are arranged in the driving seat 51, which are respectively connected to the spline nut and the screw nut. In this way, the linear movement or rotational linear movement of the ball spline screw 52 can be realized by controlling different motors.

[0027] In order to clamp the car chain seat 8, a fixed seat 4 is connected to one end of the ball spline screw 52 facing the accessory placement seat 3. The fixed seat 4 can be inserted between the two reinforcing plates of the car chain seat 8, and the fixed seat 4 is hollow. An inflatable shaft 41 is arranged at the front end of the fixed seat 4. At the same time, an electromagnetic suction cup 42 is arranged on the side of the fixed seat 4. The electromagnetic suction cup 42 can achieve expansion and contraction relative to the fixed seat 4 by inflation and deflation. The expansion and contraction of the electromagnetic suction cup 42 is consistent with the principle of the inflatable shaft 41. Therefore, in this embodiment, no detailed description is given. In this way, the inflatable shaft 41 is inserted into the through hole of the car chain seat 8, and the electromagnetic suction cup 42 is used to achieve the adsorption of the other main end face of the car chain seat 8. The main purpose of this setting is to ensure the stability of the fixation of the car chain seat 8.

[0028] In this way, by setting up the rotating lifting mechanism 5, the adsorption surface of the electromagnetic suction cup 42 and the surfaces of the reinforcing plates on both sides can be exposed. Since the rotating lifting mechanism 5 can also move linearly during the rotation process, the three end faces can be polished by utilizing the automatically movable polishing mechanism 22.

[0029] In order to realize the grinding of the end face with holes, a turning motor 6 for turning the driving seat 51 is also arranged on the workbench 1. Specifically, rotating shafts are arranged on both sides of the driving seat 51, one of which is connected to the turning motor 6, and the other is connected to the bearing seat, so that the driving seat 51 can be turned over by the turning motor 6, so that the ball spline screw 52 is arranged vertically, so that the end face with holes can be arranged upward, thereby completing the grinding of the driving end face.

[0030] Through the above-mentioned setting, the automobile chain seat 8 to be polished is placed on the accessory placement seat 3 by using a truss manipulator or a multi-automatic manipulator in a manner that the non-hole end face faces downward and the opening direction faces the rotating jacking mechanism 5. Then, the rotating jacking mechanism 5 controls the ball spline screw 52 to rotate and retract, adjusts the angle of the fixed seat 4, and sets the electromagnetic suction cup 42 downward. Then, the ball spline screw 52 is controlled to retract linearly, and the air shaft 41 is inserted into the through hole of the automobile chain seat 8, inflated, and the air shaft 41 works. The magnetic suction cup 42 is extended, and then, the electromagnetic suction cup 42 is controlled to work to achieve double fixation of the automobile chain seat 8. Then, the ball spline screw rod 52 is controlled to extend and retract to move the automobile chain seat 8 out of the accessory placement seat 3. After reaching the specified position, it is rotated and extended to expose the side and end faces in turn to complete the grinding. Then, the flip motor 6 is used to achieve a 90-degree flip, and then the end face with holes is polished. After the grinding is completed, a truss manipulator or a multi-automatic manipulator can be set on this side to remove the automobile chain seat 8 to complete the stacking.

[0031] Considering that the truss manipulator or multi-automatic manipulator may be tilted at a certain angle when placing the automobile chain seat 8, in order to ensure that the fixed seat 4 clamps it, in this embodiment, the accessory placement seat 3 is set in a box shape, and a positioning mechanism 7 is set on the accessory placement seat 3. The positioning mechanism 7 includes a positioning motor 71 set on the accessory placement seat 3 and a positioning rack 73 set on both sides of the positioning motor 71. The power end of the positioning motor 71 is equipped with a gear 72, and the gear 72 is meshed with the positioning rack 73. A connecting plate 74 is set on the positioning rack 73, and the connecting plate 74 extends out of the top of the accessory placement seat 3. The top of the accessory placement seat 3 is provided with a walking slot for the connecting plate 74 to walk. One end of the connecting plate 74 extending out of the accessory placement seat 3 is connected to a clamping seat 75 for clamping the automobile chain seat 8. In this way, under the action of the positioning motor 71, the clamping seat 75 will move relative or toward each other. Since it is an angle fine adjustment, its movement will not cause the automobile chain seat 8 to disengage.

[0032] In order to achieve accurate positioning of the automobile chain seat 8, in this embodiment, the clamping seat 75 is L-shaped, wherein one side of the clamping seat 75 is parallel to the connecting plate 74 and is arranged on the top of the connecting plate 74, and the other side of the clamping seat 75 away from the connecting plate 74 is provided with a right-angle notch 751, and the clamping seat 75 clamps the two side surfaces of the automobile chain seat 8 body through the right-angle notch 751. It should be noted that the thickness of the clamping seat 75 is slightly less than or equal to the thickness of one side end surface of the automobile chain seat 8.

[0033] Considering that the rotating lifting mechanism 5 needs to take the automobile chain seat 8 away from the accessory placement seat 3, if it is taken away by flipping, an additional process is added. Therefore, in order to reduce the process, in this embodiment, the two clamping seats 75 are arranged diagonally. In this way, the clamping seats 75 are located at the diagonal of the automobile chain seat 8, and their movement towards each other will cause them to deviate from the moving line of the rotating lifting mechanism 5, thereby avoiding their influence on the movement of the rotating lifting mechanism 5.

[0034] In order to reduce costs, in this embodiment, the rotary lifting mechanism 5 is arranged on one side close to the workbench 1, and a notch 11 is arranged on one side of the workbench 1 for turning the driving seat 51. At the same time, a sliding plate 12 is arranged below the notch 11, and the sliding plate 12 is arranged tilted downward. In this way, the rotary lifting mechanism 5 is turned over by the turning motor 6, so that the car chain seat 8 is separated from the fixed seat 4 under the action of gravity and falls into the heat treatment basket below the sliding plate 12, and then, when the basket is full, heat treatment can be carried out.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
