Technical Field

[0001] The utility model relates to the technical field of ductile iron casting production, in particular to a clamping tool for ductile iron casting production. Background Art

[0002] With the rapid development of modern industry, ductile iron, as a material with excellent mechanical properties, has been widely used in many fields such as automobiles, machinery, and construction. In the production and processing of ductile iron castings, clamping tools play a vital role. They are responsible for stably clamping the castings during the processing to ensure their accurate positioning, thereby achieving high-precision processing requirements. The performance of the clamping tools directly affects the processing quality and production efficiency of the castings. The clamping tools on the market currently have a relatively simple structure and can only clamp block-shaped or cylindrical ductile iron castings, resulting in the inability to meet the clamping needs of various shapes. When clamping ductile iron castings of different shapes, different fixtures often need to be replaced. The replacement operation process is relatively complicated, which can easily delay the processing efficiency and bring more troubles to the processing operation of ductile iron castings. Therefore, it is necessary to design a clamping tool for the production of ductile iron castings. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model proposes a clamping tool for producing ductile iron castings, including a base 1, a clamp assembly 3 and a support frame 4. A support leg 104 is fixedly installed at the bottom of the base 1, and an anti-skid pad is adhered to the bottom of the support leg 104. The support leg 104 can be used to support the device conveniently, so that the device can be placed in a suitable position for use and operation. A sliding frame 2 is slidably installed on the top of the base 1. The base 1 and the sliding frame 2 are slidably installed through a slide groove 103, so that the sliding frame 2 can move horizontally left and right on the surface of the base 1. An installation groove 101 is opened on the inner side of the base 1. A bidirectional screw rod 102 is rotatably installed inside the installation groove 101, and a turntable 105 is fixedly installed at one end of the bidirectional screw rod 102. By using the turntable 105, the bidirectional screw rod 102 can be conveniently operated to rotate forward and reverse. A threaded sleeve 201 is fixedly installed at the bottom of the sliding frame 2. The bidirectional screw rod 102 passes through the threaded sleeve 201. The bidirectional screw rod 102 and the threaded sleeve 201 are threadedly engaged. Through the reverse thread on the bidirectional screw rod 102, the threaded sleeve 201 can be driven to move away from and towards each other, and the sliding frame 2 can be synchronously driven to move away from and towards each other.

[0022] The top of the sliding frame 2 is fixedly connected to the support frame 4 by bolts, and a movable groove 402 is provided on the inner side of the support frame 4, and a clamp assembly 3 is slidably installed on the inner side of the movable groove 402. The clamp assembly 3 includes a clamp seat 301, a track groove 302 and an anti-sliding block 303. The top and bottom of the clamp seat 301 are provided with a track groove 302, and the track groove 302 and the movable groove 402 are slidably connected by a sliding pile 401. The surface of the clamp seat 301 is equidistantly provided with anti-sliding blocks 303. The sliding frames 2 move closer to each other, and the clamp assembly 3 can be driven to close, so that the ductile iron casting can be clamped conveniently. The clamp seat 301 is semicircular in shape, and the sliding pile 401 can slide along the track groove 302 The movable groove 402 can make the curved surface end of the clamp seat 301 flip horizontally, and the flat surface end of the clamp seat 301 can clamp and fix the block-shaped ductile iron casting. At the same time, when clamping the cylindrical ductile iron casting, the curved surface end of the clamp seat 301 can be horizontally rotated in the movable groove 402, and the flat surface end of the clamp seat 301 can be horizontally flipped, so that the cylindrical ductile iron casting can be clamped. The clamp seat 301 can automatically switch the clamping without the need for replacement operation, which effectively improves the processing efficiency. The anti-sliding block 303 can increase the friction between the clamp seat 301 and the ductile iron casting to avoid slipping during clamping.

[0023] The clamp assembly 3 also includes an air outlet 304 and a cavity 305. The cavity 305 is opened inside the clamp seat 301, and the air outlet 304 is opened on the surface of the clamp seat 301 between the anti-sliding blocks 303, and the air outlet 304 is communicated with the cavity 305. A fan 5 is fixedly installed on one side of the support frame 4 by bolts, and an air supply hose 501 is fixedly installed between the fan 5 and the clamp seat 301, and the air supply hose 501 is communicated with the cavity 305, so that the airflow can be conveniently transported to the cavity 305 through the air supply hose 501 through the fan 5. Due to the flexibility of the air supply hose 501, the horizontal flipping operation of the clamp seat 301 can be maintained. The airflow in the cavity 305 can be discharged through the air outlet 304, so that the clamping position of the ductile iron casting can be blown, and impurities on the surface of the clamping position of the ductile iron casting can be blown off, effectively avoiding squeezing of impurities and causing concave damage to the surface of the ductile iron casting.

[0024] The working principle of the clamping tool for producing ductile iron castings based on the embodiment is: by placing the ductile iron casting on the base 1 between the clamp assemblies 3, and by using the turntable 105 to drive the bidirectional screw 102 to rotate, the threaded sleeve 201 can be used to drive the sliding frame 2 to move closer to each other, and the support frame 4 can be driven to move closer to each other synchronously, so that the clamp assembly 3 can clamp the ductile iron casting, and the sliding pile 401 can slide along the track groove 302, so that the clamp seat 301 can be horizontally flipped in the movable groove 402, and when clamping the block-shaped ductile iron casting, the clamp seat 301 can be horizontally flipped back to the original position, so that the block-shaped ductile iron casting can be clamped conveniently. When clamping the cylindrical ductile iron casting, the clamp seat 301 can be horizontally flipped in the movable groove 402, and the plane position of the clamp seat 301 can be horizontally tilted, so that the clamp seat 301 can clamp and fix the cylindrical ductile iron casting. In the process of clamping the ductile iron casting, the fan 5 is started to generate airflow, and the air supply hose 501 can be used to transport the airflow into the cavity 305 and blow it out through the air outlet 304, so as to blow air to the clamping position of the ductile iron casting, and impurities on the surface of the clamping position of the ductile iron casting can be blown off, so as to avoid squeezing the impurities between the workpiece and the clamping, thereby avoiding the situation where the surface of the ductile iron casting is concave and damaged.
