[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Due to the special requirements of some castings, the casting bodies formed therefrom have irregular shapes. In the prior art, when fixing casting accessories, they are mostly fixed by means of splints. However, since the surface curvature of the irregular casting body is too large, it is easy for the splints to be unable to stably fix it, causing the casting to easily shake during detection, thereby affecting the detection effect of the device on the casting. The following describes a workpiece detection device for castings provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] Combination Figure 1 , Figure 2 and Figure 3 As shown, a workpiece detection device for castings includes a shell mechanism 1 as the main body of the device, and the shell mechanism 1 is used to connect and fix various mechanisms. The shell mechanism 1 is provided with a detection mechanism 2, and the detection mechanism 2 is used to perform pressure detection on the casting. Two fixing mechanisms 3 are provided on the workbench 101, and the two fixing mechanisms 3 are used to fix irregular castings, thereby improving the applicability of the device to different castings.

[0025] The fixing mechanism 3 includes a threaded hole a provided on the side plate 103, an adjusting screw 301 is connected to the threaded hole a, two limit blocks 303 are fixedly connected to one side of the side plate 103, and limit holes 304 are provided on the two limit blocks 303, a fixing rod 302 is fixedly connected between the two limit blocks 303, and a threaded hole b is provided on the fixing rod 302, one end of the adjusting screw 301 is provided with a fixing assembly 305 for clamping the non-standard casting, and the other end of the adjusting screw 301 passes through the side plate 103 and is provided with a fixing assembly 305 for adjusting The locking assembly 306 for adjusting and locking the section screw 301 controls the adjustment screw 301 to rotate in the threaded hole a, and determines the position of the threaded hole b through the fixing rod 302, thereby ensuring the stable movement of the fixing assembly 305. The moving path of the fixing assembly 305 is limited by the two limit blocks 303 and the limit holes 304 opened therein, and the casting bodies of different specifications are fixed by the fixing assembly 305. The position of the fixing assembly 305 is locked and fixed by the locking assembly 306, thereby ensuring the stability during the fixing process.

[0026] The fixing assembly 305 includes a connecting plate 3051 rotatably connected to one end of the adjusting screw 301, two sliding rods 3052 are fixedly connected to one side of the connecting plate 3051, and the two sliding rods 3052 slide in the two limiting holes 304 respectively, and two concave blocks a3053 and two concave blocks b3054 are fixedly connected to one side of the connecting plate 3051, round rods a are fixedly connected to the two concave blocks a3053, and support rods a3057 are rotatably connected to the round rods a, and the two concave blocks b3054 are provided with sliding grooves 3055, and sliders are slidably connected in the two sliding grooves 3055, and concave blocks c3056 are fixedly connected to one side of the two sliders, round rods b are fixedly connected to the two concave blocks c3056, and support rods b3058 and c3059 are rotatably connected to the round rod b, and support rods a3057 and b3058 and support rods b3059 are rotatably connected. A clamping block 30510 is rotatably connected between 3058 and the end of the support rod c3059 away from the connecting plate 3051. By controlling the adjusting screw 301, the adjusting screw 301 is rotated in the threaded hole b on the fixed rod 302, so that the adjusting screw 301 drives the connecting plate 3051 to move, and the sliding rod 3052 slides in the limiting hole 304, so that the two concave blocks a3053 and the two concave blocks b3054 move synchronously with the connecting plate 3051. When the clamping block 30510 contacts the casting, the concave block c3056 slides in the slide groove 3055 in the concave block b3054, so that the support rods a3057, b3058 and c3059 can be adaptively adjusted according to the contour of the casting, so that the clamping block 30510 can also stably clamp irregular castings, thereby ensuring the detection effect of the device on different castings.

[0027] The shape of the clamp block 30510 is composed of a rectangular parallelepiped and two cylinders. The clamp block 30510 is rotatably connected to the support rods a3057, b3058 and c3059, thereby ensuring that the clamp block 30510 can fix both the curved surface and the flat surface of the casting.

[0028] Embodiment 2:

[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that the surface curvature of the casting is too large or the surface is uneven, which makes it easy for the splint to be unable to stably fix it and the applicability is low. However, after the adjustment of the adjusting screw 301 is completed, if it is not locked and fixed, the stability of the fixing component 305 on the casting is low, which is easy to affect the detection effect of the device.

[0030] Combination Figure 1 and Figure 4As shown, the locking assembly 306 includes an adjusting rod 3061 fixedly connected to one end of the adjusting screw 301, one end of the adjusting rod 3061 is fixedly connected to two triangular blocks 3062, one side of the side plate 103 is fixedly connected to a circular thin wall a3063, a circular thin wall b3064 is clamped in the circular thin wall a3063, the inner wall of the circular thin wall b3064 is fixedly connected to a gear ring, the gap between the two triangular blocks 3062 is clamped with the gear ring, and the adjusting screw 301 is rotated and adjusted by the adjusting rod 3061. When the fixing component 305 has completed fixing the casting, the circular thin wall b3064 is installed to the inner side of the circular thin wall a3063. At this time, the gap between the two triangular blocks 3062 at one end of the adjusting rod 3061 can fit with the toothed ring on the inner side of the circular thin wall b3064, thereby completing the locking and fixing of the adjusting rod 3061, which greatly improves the stability of the fixing component 305 on the casting. When the fixing component 305 needs to be adjusted, the circular thin wall a3063 can be separated from the circular thin wall b3064.

[0032] The detection mechanism 2 includes a cylinder 201 installed at the bottom of the fixed plate 104, the movable end of the cylinder 201 is fixedly connected to the pressure plate 202, and one side of the storage container 102 is rotatably connected to the protective door 203, and the protective door 203 is provided with an observation window 204 for observing the detection value. The casting is pressurized by the cylinder 201 and the pressure plate 202, the internal detector is protected by the protective door 203, and the pressure detection value of the casting is observed through the observation window 204.
