In this way, the iron chips will be wrapped around the tool, causing the iron chips to scratch the processing surface and break the tool. The iron chips wrapped around the tool are easy to accumulate and get stuck in the claw clamp, which will cause the claw clamp accuracy to decrease. At the same time, when the iron chips accumulate, the machine needs to be stopped for removal, affecting production efficiency. The fixed unloading device affects the movement of the tool and is often set at a distance from the product. The product falls from the clamp onto the unloading device, which is easy to cause damage to the product and the unloading device.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0025] A bearing ring turning and clamping device according to the present invention, Figure 1-3 As shown, it includes a clamping jaw 1, a positioning support 2, a discharge ring 3, a driving device and a control device. The discharge ring 3 has a trumpet-shaped discharge channel inside, so that iron chips are discharged from the discharge channel in the discharge ring 3. The discharge ring 3 is arranged in the positioning support 2. The control device controls the clamping jaw 1 to clamp the product, and controls the driving device to drive the discharge ring 3, the clamping jaw 1 and the positioning support 2 to rotate. The product is attached to the end face of the positioning support 2. Those skilled in the art can change the chip discharge direction of the iron chips by changing the turning angle using the existing technology. The iron chips generated by turning are discharged from the discharge channel in the discharge ring 3. Since the iron chips are discharged in time and the chip discharge direction is opposite to the direction in which the blade 8 enters the product, the iron chips will not be entangled with the blade or accumulated, which avoids the iron chips from being stuck in the clamping jaw 1 due to accumulation, thereby reducing the accuracy of the clamping jaw 1.
[0026] In a specific embodiment, if Figure 2-3As shown, it also includes a reset device 4, the discharge ring 3 is slidably connected to the positioning support 2, the discharge ring 3 is arranged in the positioning support 2, the side of the discharge ring 3 with the product placed protrudes from the positioning support 2, the reset device 4 is arranged between the discharge ring 3 and the positioning support 2, the reset device 4 can be a spring, one end of the reset device is connected to the positioning support 2, and the other end is connected to the discharge ring 3, the side of the discharge ring 3 with the product placed protrudes from the positioning support 2, when a thrust is given to the discharge ring 3, the discharge ring 3 moves into the positioning support 2, when the thrust is lost, the discharge ring 3 is acted upon by the reset device 4, so that the discharge ring 3 returns to its original position; in addition, there is also a spring on the discharge ring 3 A retaining spring 5 is provided to limit the sliding range of the discharge ring 3 in the positioning support 2. When the discharge ring 3 is in the starting position, it is acted upon by the reset device 4 and the retaining spring 5, and the end face of the discharge ring 3 protrudes from the positioning support 2. When the discharge ring 3 is pushed, the discharge ring 3 is pushed to the left and moves into the positioning support 2. When the discharge ring 3 is released, it is acted upon by the reset device 4 and moves to the right. When it reaches the starting position, the retaining spring 5 is blocked and the discharge ring 3 cannot continue to move to the right. In addition, when the product processing is completed, the discharge ring 3 pushes out the iron filings around the discharge ring 3 when it is reset, thereby effectively preventing the residual iron filings from falling into the clamp 1 and affecting the accuracy of the clamp 1.
[0027] In a specific embodiment, when placing a product, the product may have defects, or the product may be placed at an angle, or the clamping jaws may not be firmly grasped during processing and rotation, etc., which may affect the processing of the product and even damage the equipment. Figure 1 and 4 As shown, a detection device 6 is also included. The detection device 6 is arranged on the positioning support 2 and is used to detect whether the product is placed in place. The detection device 6 includes a rotary joint 61, at least one air pipe 62 connected to the rotary joint 61 and a pressure sensor 63 for measuring the air pressure in the air pipe. Compressed air is continuously transported from the rotary joint 61 to the air pipe 62. When the product is placed in place, one end of the air pipe 62 is blocked, and the gas in the air pipe 62 cannot be discharged. The pressure value measured by the pressure sensor 63 increases, indicating that the installation is in place. The pressure sensor 63 transmits a signal to the control device, and the control device controls the clamp 1 to clamp the product. When the product is placed at an angle, the air pipe 62 is not completely blocked, and the air pressure in the air pipe 62 measured by the air pressure sensor 63 does not reach the standard, indicating that the product is not placed in place; preferably, three air pipes 62 are provided, and the number of air pipes 62 is increased to increase the detection points for product placement. The three air pipes 62 are arranged on the positioning support 2 at equal intervals, and the end faces of the three air pipes 62 are flush with the end face of the discharge ring 3 to ensure that the air pipe 62 does not affect the placement of the product.
[0028] In a specific embodiment, if Figure 5As shown, it also includes a feeding device 7, which is arranged on one side of the clamping jaw 1 and is used to classify and store the products in the clamping jaw 1.

After completion, the control device drives the first actuator 71 to move the first guide rail 73 to the product, the clamp 1 opens, the product is pushed by the discharge ring 3, the product is pushed out, and falls into the first guide rail 73. The product passes through the first guide rail 73 and the second guide rail 74, and finally falls into the good product slot. The first actuator 71 drives the first guide rail 73 to reset; when the product is not placed flat, the first actuator 71 moves the first guide rail 73 to the product, the control device drives the second actuator 72 to drive the second guide rail 74 to move, one end of the second guide rail 74 moves to the inspection slot, the clamp 1 opens, the product is pushed by the discharge ring 3, the product is pushed out, and falls into the first guide rail 73. The product passes through the first guide rail 73 and the second guide rail 74, and finally falls into the inspection slot.

The product passes through the first guide rail 73 and the second guide rail 74 and finally falls into the good product slot. The first actuator 71 drives the first guide rail 73 to reset. When the product is being processed, the product is displaced because the clamping jaw 1 is not clamped, the air pressure in the air pipe 62 decreases, and the signal is transmitted to the control device. The control device controls the driving device to stop, and the control device drives the first actuator 71 to move the first guide rail 73 When the product reaches the inspection slot, the control device drives the second actuator 72 to drive the second guide rail 74 to move.
