Technical Field

[0001] The utility model relates to the field of automobile parts manufacturing, in particular to a clutch plate surface treatment device. Background Art

[0002] Automobile clutch plates, also known as friction plates or clutch facing plates, are the main working parts of the clutch. Automobile clutch plates use glass fiber, polymethyl methacrylate fiber, aramid fiber, copper wire and other fibers as skeleton materials, various resins, rubbers and other adhesives, and add appropriate amounts of metals and non-metals and their compounds as friction performance regulators and fillers. After high temperature and high pressure compounding to form blanks, they are polished, drilled and other surface processing procedures to obtain finished products. The polishing process is mainly to obtain a certain surface roughness.

[0003] The existing automobile clutch plate grinding device generally fixes the clutch plate relatively, sends it to the grinding place, rotates the grinding wheel, and grinds the clutch plate as an active part, and retracts the clutch plate after grinding, such as the scheme recorded in CN202192523U, a clutch surface plate grinding device. This scheme first places and fixes a clutch plate, waits for the processing to be completed, and then removes and places the next one, which is labor-intensive and inefficient. Utility Model Content

[0009] The guide rail assembly is fixed to the frame and supports the movable tray.

[0010] The unloading mechanism delivers the clutch plate to the bottom of the grinding wheel mechanism 3 for grinding, and then unloads it during the return process. The clutch plate falls from the drop hole on the frame and enters the next process.

[0011] According to a further improvement, the guide rail assembly comprises a guide rail and a lead screw mounted on a frame, wherein the lead screw is driven by a stepping motor.

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] This embodiment provides a clutch plate surface treatment device, the overall structure of which is as follows Figure 1 As shown, it includes a frame 1, on which a feeding and unloading mechanism 2 and a grinding wheel mechanism 3 are installed. The feeding and unloading mechanism 2 has a moving tray 2-2, and the moving tray 2-2 sends the clutch plate to the bottom of the grinding wheel mechanism 3 for grinding, and then unloads the material during the return process, and the clutch plate falls from the drop hole 1-1 on the frame to enter the next process.

[0051] The frame 1 can be a platform type or a frame type. The platform type is used as an example in the figure of this embodiment. The platform type frame needs to have a drop hole 1-1 for the polished clutch plate to fall therefrom.

[0052] The feeding and unloading mechanism 2 is the main improved part of this embodiment. Figure 2 As shown, the feeding and unloading mechanism 2 includes a material rack 2-1, a movable tray 2-2, and a guide rail assembly 2-3 supporting the movable tray 2-2.

[0053] The guide rail assembly 2-3 includes a guide rail 2-3-1 and a lead screw 2-3-2 mounted on a frame, and the lead screw 2-3-2 is driven by a stepper motor.

[0054] like Figure 2-3As shown, the mobile pallet 2-2 includes a support rod 2-2-1, and both ends of the support rod 2-2-1 cooperate with the guide rail 2-3-1 and are driven by the lead screw 2-3-2. An annular pallet 2-2-2 is arranged in the middle of the support rod 2-2-1, and the main body of the annular pallet 2-2-2 is an annular arm 2-2-6, along which four telescopic support structures are installed, and each telescopic support structure includes an electromagnetic push rod 2-2-3, which is installed on the annular arm through a mounting block 2-2-4. The output end of the electromagnetic push rod 2-2-3 is fixedly connected to the telescopic tongue 2-2-5 of the mobile pallet. The telescopic tongue 2-2-5 of the mobile pallet is installed in a wall hole opened in the annular arm. The electromagnetic push rod 2-2-3 is connected to direct current, and its movement is controlled by a control cabinet. The working principle of the electromagnetic push rod can be referred to CN213243787U- an electromagnetic push rod. When the output end of the electromagnetic push rod is in the extended state, it pushes the telescopic tongue 2-2-5 of the mobile tray to be exposed from the annular arm 2-2-6, which can play the role of supporting the clutch plate. When the output end of the electromagnetic push rod is in the retracted state, it pulls the telescopic tongue 2-2-5 of the mobile tray to retract from the outside of the annular arm 2-2-6, allowing the clutch plate to fall. Figure 4 shown.

[0055] The rack 2-1 includes a rack support rod 2-1-1, a rack body 2-1-2, and a clamping mechanism 2-1-3. The rack body 2-1-2 can be a cylindrical structure or a cage structure, with an open top to place the clutch plates in batches. The example diagram shows a cylindrical structure. The rack body 2-1-2 is fixed to the frame through the rack support rod 2-1-1.

[0056] The clamping mechanism 2-1-3 is installed at the bottom of the rack body, and its structure and working mode are basically the same as the telescopic support structure of the mobile tray 2-2. Figure 5 As shown. The difference is that the four retractable tongues 2-1-4 of the clamping mechanism become the clamping part, which can clamp the edge of more than one clutch plate to prevent the clutch plate from falling. The size design of the retractable tongue 2-1-4 of the clamping mechanism needs to meet certain requirements, that is, the distance between its lower edge and the upper surface of the retractable tongue 2-2-5 of the moving tray should be between one clutch plate thickness and two clutch plate thicknesses, preferably equal to one clutch plate thickness. In this way, when the moving tray moves the clutch plate at the bottom, the position of other clutch plates can be kept unchanged. The height of the retractable tongue 2-1-4 of the clamping mechanism can be the thickness of multiple clutch plates to improve the clamping stability, and the end surface of the retractable tongue of the clamping mechanism can be provided with rubber pads and other materials that increase friction and have a certain protective effect.

[0057] The grinding wheel mechanism 3 can adopt the existing grinding wheel mechanism, and its power and transmission parts are omitted in the figure.

[0058] The following describes the working process of this example:

[0059] Initial state: the clamping mechanism 2-1-3 of the material rack 2-1 is in a retracted state; the annular tray 2-2-2 of the mobile tray 2-2 is located below the material rack 2-1, and the telescopic support structure of the mobile tray 2-2 is in an extended state.

[0060] Step 1: manually place a group of clutch plates in the material rack body 2-1-2 of the material rack 2-1 (with the help of manual tools such as clamps), and the bottom layer of clutch plates falls into the annular tray 2-2-2. The supporting force of the group of clutch plates is provided by the telescopic tongue 2-2-5 of the mobile tray.

[0061] Step 2: The clamping mechanism 2-1-3 moves to the extended state, and the four clamping mechanism retractable tongues 2-1-4 clamp the second clutch plate or several clutch plates above from the bottom to the top. The stepper motor drives the moving tray 2-2 to move to the bottom of the grinding wheel mechanism 3 through the guide rail assembly to grind the clutch plate in the moving tray 2-2.

[0062] Step 3, after grinding is completed, the mobile tray 2-2 returns to the top of the blanking hole 1-1, the mobile tray telescopic tongue 2-2-5 is retracted, and the clutch plate after grinding falls from the blanking hole 1-1 to enter the next step.

[0063] Step 4, the mobile tray 2-2 continues to return to the bottom of the material rack 2-1, the mobile tray telescopic tongue 2-2-5 extends, the clamping mechanism telescopic tongue 2-1-4 retracts, and the lowest clutch plate falls into the annular tray 2-2-2, ready to be sent to the bottom of the grinding wheel mechanism 3.

[0064] Steps 2-4 are repeated in a cycle, and during this process, multiple clutch plates can be polished without manual intervention, thereby improving efficiency.

[0065] When the number of clutches in the rack 2-1 is small, a set of clutch plates can be added to the rack.

[0066] In this embodiment, the structural design of the mobile tray 2-2 is mainly to cooperate with the drop hole 1-1 for unloading, and at the same time to combine feeding and unloading, saving the setting of the unloading mechanism and reducing the cost.

[0067] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
