[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-8 The fully automatic grinding table includes a base 1, a support disk 2 on the top of the base 1, a pneumatic slip ring 3 mounted on the top of the base 1 via a bracket 17, and the pneumatic slip ring 3 connected to the input end of the divider 4 through the central opening of the support disk 2. The drive end of the divider 4 is connected to the support disk 2, and a clamping assembly is provided on the support disk 2. The divider 4 is a precision mechanism that can convert continuous operation into intermittent motion, also called a precision intermittent cam divider 4. The divider 4 is existing technology and will not be described in detail here. Here, the function of the divider 4 is to intermittently transport the workpiece to the designated position.

[0027] The clamping assembly includes four clamping seats 5 mounted on the top of the support disc 2, cylinders 6 mounted on both sides of the clamping seats 5, clamping plates 7 mounted on the drive end of the cylinders 6, a positioning plate 8 embedded on the top of the clamping seats 5, and a positioning pin 9 mounted on the top of the positioning plate 8. The four clamping seats 5 are arranged in a circular array on the support disc 2. The four clamping seats 5 are four workstations. The first workstation is a manual loading and unloading workstation, where the main work is to take out the brakes that have been polished and inspected, and to load and position the brakes that have not been polished and inspected. At the same time, a barcode reader can be installed on the clamping seat 5 of the second workstation to read the QR code information. This workstation serves as a data entry workstation. The barcode reader is an MV-ID2004M intelligent barcode reader, which can accurately enter the QR code information of the brakes into the system (not shown in the figure). The third workstation is a polishing and torque detection workstation, where automatic polishing and torque detection of the friction plates are mainly performed. The fourth workstation is a buffer workstation.

[0028] When in use, this device can position the brake using the positioning pin 9, and simultaneously clamp the brake with the clamping plates 7 on both sides. In this embodiment, there are three positioning pins 9, corresponding to the mounting bolt holes at the bottom of the brake. One positioning pin 9 is used for each type of brake, and can be replaced according to different types of brakes. During operation, the rotation of the support disc 2 is achieved through the pneumatic slip ring 3 and the divider 4 to supply the workpiece to be ground. This not only has high working efficiency, but also effectively solves the problem of poor grinding effect caused by low accuracy of brake installation position in the prior art.

[0029] In this embodiment, a number of chemical bolts 10 are installed at the bottom of the base 1, and the base 1 is leveled and fixed to the ground by means of the chemical bolts 10.

[0030] In this embodiment, the two clamping pieces 7 are symmetrically arranged, and the side of the clamping piece 7 near the positioning disk 8 is designed in a V shape to facilitate clamping and fixing the brake.

[0031] In this embodiment, a housing 11 is provided on the outside of the base 1, and the front of the housing 11 is open. The housing 11 is made of aluminum alloy and surrounds the equipment on five sides to prevent dust. The front opening facilitates manual operation.

[0032] In this embodiment, a lifting drive device is provided above the clamping assembly. The lifting drive device is installed at the rear of the base 1. A torque detection component is provided at the drive end of the lifting drive device. The lifting drive device includes a vertical electric slide 12 provided on one side of the base 1. A loading motor 13 is installed on the vertical electric slide 12. A mounting base is provided below the loading motor 13. A torque sensor 14 is installed on the mounting base and is connected to the motor shaft of the loading motor 13. An inner hole pin 15 is installed at the end of the motor shaft of the loading motor 13. After the brake reaches below the inner hole pin 15, the vertical electric slide 12 controls the loading motor 13 to move downward, so that the inner hole pin 15 is accurately inserted into the square hole of the brake friction plate. At the same time, the friction plate is polished according to a preset program (the polishing component is not shown in the figure; this device is a polishing table used in conjunction with the polishing device). The force received by the inner hole pin 15 is transmitted to the torque sensor 14 through the motor shaft to detect the torque received by the workpiece during polishing.

[0033] It also includes a manual correction structure, which includes a keyway on one side of the clamping seat 5 and a correction wrench that is movably embedded in the keyway.

[0034] In this embodiment, an exhaust device 16 is provided on the outer side of the outer shell 11 to extract the dust generated during grinding. The exhaust device 16 includes a pipe connecting the inside and outside of the outer shell 11 and an exhaust fan provided outside the pipe to extract the dust and debris generated during grinding.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
