Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example: Figure 1-3As shown, the utility model provides a fixture for processing automobile radiators that is easy to operate, including a table top 1, a placement groove 4 is opened on the top surface of the table top 1, a ejection device 2 is fixedly connected to the inside of one side of the table top 1, and four clamping devices 3 are fixedly connected to the top surface of the table top 1. The clamping device 3 includes a support 31, one side of the support 31 is rotatably connected to a connecting frame 32, the upper outer surface of the connecting frame 32 is fixedly connected to a handle 33, the inner wall of the connecting frame 32 is rotatably connected to a connecting rod 34, and the outer surface of the connecting rod 34 is rotatably connected to the Connected to the connecting frame 35, hold the handle 33 and rotate the connecting frame 32 to rotate it toward the center of the placement slot 4. As the connecting frame 32 rotates, the connection relationship between the connecting rod 34 and the connecting frame 35 will drive the connecting frame 35 to move accordingly. The outer surface of the connecting frame 35 is clamped with a clamping sleeve 36, and the threads of the two clamping sleeves 36 are inserted with screws 37. The screws 37 are located inside the connecting frame 35. The outer surface of the screw 37 is threaded with two nuts 38, and the bottom end of the screw 37 is fixedly connected to a pressure block 39.
[0020] When the pressing block 39 contacts the surface of the radiator, continue to rotate the connecting frame 32, and two nuts 38 are threadedly sleeved on the outer surface of the screw 37. The pressure of the pressing block 39 on the radiator can be controlled by adjusting the position of the nut 38 on the screw 37, which can effectively clamp the car radiator firmly.
[0021] The ejection device 2 includes a fixed box 201, one side of the fixed box 201 is fixedly connected to the table 1, and a rotating shaft 202 is movably passed through both sides of one end of the table 1. One end of the rotating shaft 202 is rotatably connected to the inner wall of one side of the table 1, and the other end of the rotating shaft 202 is rotatably connected to the inner wall of one side of the fixed box 201. A sprocket 203 is fixedly sleeved on the outer surface of the rotating shaft 202, and the outer surfaces of the two sprockets 203 are meshed with a chain 204. A motor 205 is fixedly connected to one side of the fixed box 201, and the output end of the motor 205 extends into the fixed box 201 and is fixedly connected to one end of the rotating shaft 202. When the rotating shaft 202 rotates, the sprocket 203 fixedly sleeved on its outer surface will rotate accordingly, and the meshing connection of the chain 204 makes the other sprocket 203 also rotate synchronously, thereby To ensure the synchronous movement of the two cams 206, the outer surface of the rotating shaft 202 is fixedly sleeved with the cam 206, and the lower inner wall of the placement slot 4 is provided with four through slots 207 distributed in a rectangular array. The inner wall of the through slot 207 is fixedly connected to a fixed frame 208. The cross-section of the fixed frame 208 is U-shaped, and a push rod 209 is movably passed through the lower inner wall of the fixed frame 208. The bottom end of the push rod 209 is fixedly connected to a slide plate 210. The outer surface of the cam 206 fits the outer surface of the slide plate 210. The outer surface of the push rod 209 is sleeved with a spring 211. The upper and lower ends of the spring 211 are fixedly connected to the bottom surface of the fixed frame 208 and the outer surface of the slide plate 210 respectively.

[0022] As the rotating shaft 202 rotates, the outer surface shape of the cam 206 will push the slide plate 210 to move upward. When the slide plate 210 moves upward, it will compress the spring 211 and drive the push rod 209 to move upward. The top plate 212 at the top of the push rod 209 will move upward in the through groove 207 and gradually protrude into the placement groove 4, lifting the car radiator placed in the placement groove 4 from the bottom, making it convenient to take out the processed car radiator.
[0023] The nut 38 is threadedly sleeved on the outer surface of the screw 37 so that the pressure of the pressure block 39 on the radiator can be controlled by adjusting the position of the nut 38 on the screw 37 so that the pressure of the pressure block 39 on the radiator can be controlled.
[0024] When the processed radiator needs to be taken out from the placement groove 4, the motor 205 is started, and the output end of the motor 205 drives the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, the sprocket 203 fixed on its outer surface will rotate accordingly. Through the meshing connection of the chain 204, the other sprocket 203 also rotates synchronously, thereby ensuring the synchronous action of the two cams 206. As the rotating shaft 202 rotates, the outer surface shape of the cam 206 will push the slide plate 210 to move upward. When the slide plate 210 moves upward, it will compress the spring 211 and drive the push rod 209 to move upward. The top plate 212 at the top of the push rod 209 will move upward in the through groove 207 and gradually protrude into the placement groove 4, lifting the automobile radiator placed in the placement groove 4 from the bottom, thereby achieving the purpose of conveniently taking out the processed automobile radiator.
