Description

Technical Field

[0001] This utility model relates to the field of grinding disc replacement fixtures, and in particular to an automatic grinding disc replacement fixture for stainless steel grinding discs. Background Technology

[0002] In industry, grinding is a common processing method. It utilizes abrasive particles coated or embedded on grinding tools to process the surface of the workpiece by means of the relative movement between the grinding tools and the workpiece under certain pressure, thereby improving the surface finish or smoothness of the workpiece to meet the requirements of production and application.

[0003] In the current grinding and machining field, grinding discs gradually lose their processing efficiency due to continuous wear during use. When the wear reaches a critical threshold, new discs need to be replaced. However, existing technologies mainly rely on manual methods for replacing grinding discs. As production scale expands and grinding volume increases, the wear rate of grinding discs increases accordingly, leading to a sharp increase in replacement frequency. This increases the workload of operators and affects production efficiency and operational continuity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic tooling for changing stainless steel grinding discs.

[0005] An embodiment of this utility model provides an automatic stainless steel grinding disc replacement fixture, comprising:

[0006] A workbench, on which a robotic arm is mounted, and at the end of the robotic arm is a motor, the output end of which is connected to a grinding disc;

[0007] A connecting assembly includes a mounting cylinder, a positioning cylinder, and two locking pins. The mounting cylinder is fixedly mounted on the output end of the motor, and the positioning cylinder is fixedly mounted on the grinding disc. Both locking pins slide through the mounting cylinder. A limit plate is fixedly mounted on the inner side of each locking pin, and a spring is fixedly mounted on the limit plate. The other end of the spring is fixedly mounted on the inner wall of the mounting cylinder.

[0008] A release assembly for separating the mounting cylinder and the grinding disc.

[0009] Furthermore, the release assembly includes a pull rope and a movable column. The two ends of the pull rope are respectively fixedly mounted on two limiting plates. Two positioning rings are fixedly mounted on the inner bottom of the mounting cylinder. The movable column slides through the mounting cylinder, and a pull ring is fixedly mounted on the bottom of the movable column.

[0010] Furthermore, a receiving box is fixedly installed on the worktable, and the receiving box is used to store the grinding discs to be replaced.

[0011] Furthermore, an L-shaped fixing plate is fixedly installed on the workbench, and a collection box is installed on one side of the workbench.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-3 As shown in the figure, this utility model embodiment proposes an automatic stainless steel grinding disc replacement fixture, including:

[0024] A worktable 1 is equipped with a fixed receiving box 15 for storing grinding discs 4 to be replaced. A robotic arm 2 is mounted on the worktable 1. The robotic arm 2 utilizes existing mature technology and a high-precision servo control system to achieve precise positioning and trajectory planning of the end effector, enabling automated operation of complex machining processes. This robotic arm system has multi-axis linkage capabilities, allowing it to perform highly repetitive precision machining operations according to preset programs, ensuring the stability and consistency of the machining process. A motor 3 is mounted at the end of the robotic arm 2, and the output end of the motor 3 is connected to the grinding disc 4, driving the grinding disc 4 to rotate for grinding.

[0025] The connecting assembly includes a mounting cylinder 5, a positioning cylinder 11, and two locking pins 6. The mounting cylinder 5 is fixedly mounted on the output end of the motor 3, and the positioning cylinder 11 is fixedly mounted on the grinding disc 4. The positioning cylinder 11 is sleeved on the outer end of the mounting cylinder 5 and serves to position the grinding disc 4. Locking holes 12 are provided through both sides of the positioning cylinder 11.

[0026] Both locking posts 6 are slidably disposed through the mounting cylinder 5. The locking posts 6 can be engaged into the locking holes 12 of the same cylinder, thereby fixing the positioning cylinder 11 and the grinding disc 4. The bottom of the outer end of the locking post 6 is set with an incline, so that pressing the incline of the locking post 6 can push the locking post 6 inward. A limiting plate 7 is fixedly disposed on the inner side of the locking post 6, and a spring 8 is fixedly disposed on the limiting plate 7. The other end of the spring 8 is fixedly disposed on the inner wall of the mounting cylinder 5, so that the locking post 6 can be elastically connected to the mounting cylinder 5 through the spring 8.

[0027] The release assembly is used to separate the mounting cylinder 5 and the grinding disc 4. The release assembly includes a pull rope 9 and a movable column 13. The two ends of the pull rope 9 are respectively fixed on two limit plates 7. Two positioning rings 10 are fixedly installed at the inner bottom of the mounting cylinder 5. The positioning rings 10 guide the pull rope 9.

[0028] The movable column 13 slides through the mounting cylinder 5, and a pull ring 14 is fixedly installed at the bottom of the movable column 13. The pull ring 14 is located between two positioning rings 10, and the pull rope 9 passes through the positioning rings 10 and the pull ring 14, so that the movable column 13 can pull the pull rope 9 through the pull ring 14.

[0029] An L-shaped fixing plate 16 is fixedly installed on the workbench 1. The L-shaped fixing plate 16 is used to compress the movable column 13. A collection box 17 is provided on one side of the workbench 1. The collection box 17 is used to collect the scrapped grinding discs 4.

[0030] The detailed working process of this utility model is as follows:

[0031] 1. During installation, the mechanical arm 2 drives the installation cylinder 5 to be inserted into the positioning cylinder 11, so that the positioning cylinder 11 presses the inclined surface of the locking post 6, pushes it inward, and stretches the spring 8; when the locking post 6 moves to be aligned with the locking hole 12, the locking post 6 pops out and resets under the elastic action of the spring 8, and locks into the locking hole 12, thus fixing the grinding disc 4.

[0032] 2. During dismantling, the mechanical arm 2 moves the installation cylinder 5 to the L-shaped fixing plate 16, and the L-shaped fixing plate 16 presses one end of the movable column 13, pushing it to the other end. The movable column 13 pulls the pull rope 9 through the pull ring 14, thereby pulling the locking column 6 inward, separating it from the locking hole 12. At this time, the grinding disc 4 can automatically fall into the collection box 17.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
