Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a salt spray test piece grinding device. Background Technique

[0002] Salt spray test is an environmental test that mainly uses the artificial simulated salt spray environment created by salt spray test equipment to evaluate the corrosion resistance of products or metal materials. It is divided into two categories. One is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. Metal test pieces are required for the experiment. In order to ensure the accuracy of the experiment, the test pieces need to be ground, which requires the use of a grinding mechanism.

[0003] At present, in the market, most grinding mechanisms can only grind the outer surface of samples in the same device, but cannot grind the inner circle of the holes in the samples. If grinding is required, another device needs to be used, which is rather inconvenient in operation. Therefore, a salt spray test piece grinding device is proposed to solve the above problems.

[0009] The second fixing mechanism includes an electric slide rail, a mounting rod, a second fixing frame, a motor, a sleeve rod, an electric telescopic rod, a fixing groove and a fixing block. Electric slide rails are installed on both sides inside the mounting frame. An mounting rod is connected between the two electric slide rails. A second fixing frame is installed at the bottom of the mounting rod. A motor is installed on the side wall of the second fixing frame. A sleeve rod is rotatably connected to the side wall of the second fixing frame. An electric telescopic rod is rotatably connected to the side wall of the second fixing frame away from the motor.

[0011] Furthermore, a grinding head is installed on the rotating rod, and one end of the threaded rod close to the clamping plate is fixedly connected to the clamping plate.

[0012] In the grinding device of the present utility model, the grinding head can be used to grind both the inner ring and the outer ring of the specimen.

[0013] Furthermore, two first baffles are fixedly installed on the outer wall of the sleeve rod, and two second baffles are fixedly installed outside the fixing block.

[0014] In the grinding device of the present utility model, when the specimen is sleeved outside the sleeve rod, one side of the specimen abuts against the first baffle.

[0027] A cylinder 501 is fixedly installed on the side wall of the mounting bracket 1. A first fixing bracket 502 is fixedly installed at the free end of the cylinder 501. Two clamping plates 503 are slidably connected inside the first fixing bracket 502. Limiting grooves 504 are formed on the adjacent side walls of the two clamping plates 503. Two threaded rods 505 are threadedly connected to the first fixing bracket 502. When the inner ring of the specimen needs to be polished, the two sides of the specimen can be first placed in the limiting grooves 504, and the threaded rods 505 are rotated to drive the two clamping plates 503 to move to fix the two ends of the specimen. Then, the cylinder 501 is controlled to drive the specimen towards the grinding head 4. The size of the grinding head 4 needs to conform to the inner diameter of the specimen. Until the grinding head 4 contacts the inner ring of the specimen, and then the grinding motor 2 is controlled to drive the grinding head 4 to rotate for grinding.

[0028] Electric slide rails 601 are installed on both sides inside the mounting bracket 1. An installation rod 602 is connected between the two electric slide rails 601. A second fixing bracket 603 is installed at the bottom of the installation rod 602. A motor 604 is installed on the side wall of the second fixing bracket 603.
