[0001] The utility model relates to foundry processing auxiliary frock technical field, concretely relates to a manual core setting clamp, can when the automatic equipment failure, assist the manual core setting operation of operating personnel, ensure the continuous operation of production line. BACKGROUND
[0002] In the casting production process, the accurate positioning and core setting operation of sand core are the key steps to ensure the quality of castings. With the popularization of automatic production line, many foundries have realized the automation of many production links. However, the automatic equipment may fail in some cases, such as air bag wear, insensitive electrical signal sensing and other problems, resulting in core setting failure. At this time, the production line has to be stopped for waiting, which seriously affects the production efficiency and economic benefits.
[0003] In order to solve this problem, the existing solution is usually to use manual core setting operation. However, due to the complex structure of sand core, the high accuracy requirement of core setting position and the heavy weight of sand core (usually more than 10KG), direct manual operation is not only difficult, but also has safety hazards. Therefore, a tool is needed to assist manual core setting, so that the production line can still keep continuous running when the automatic equipment fails. SUMMARY
[0004] The utility model aims at overcoming the defects in the prior art, providing a manual core setting clamp, which can assist the manual core setting operation of operating personnel when the automatic equipment fails, ensure the continuous operation of production line, and solve the problems of low accuracy, difficult operation and safety risk of existing manual core setting.

[0006] Further optimization, limiting rings are arranged at both ends of the sleeve on the horizontal rod of the movable part, and the limiting rings are fixedly welded on the horizontal rod, and the two ends of the wrench are fixedly connected to the two limiting rings respectively.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0020] like Figures 1 to 3 As shown, this utility model provides a manual core clamp, including a movable part 1, a fixed part 4, a limiting part 3, a wrench 2, a limiting rubber sleeve 5, and a connecting rod 6. The movable part 1 is a U-shaped structure with two vertical rods fixedly connected to both ends of a horizontal rod. The fixed part 4 is a U-shaped structure with two vertical rods fixedly connected to both ends of a horizontal rod. The connecting rod 6 is a straight rod, and one end of the straight rod is fixedly connected to a sleeve perpendicular to the straight rod. The horizontal rod of the movable part 1 passes through the sleeve. Limiting rings are provided at both ends of the sleeve on the horizontal rod of the movable part 1. The limiting rings are circular ring structures fixedly connected to the horizontal rod. The outer diameter of the circular ring is the same as the outer diameter of the sleeve. The end of the wrench 2 has a bent section in the same direction. The middle section of the wrench 2 is a long strip handle. The direction of the middle section of the wrench 2 is the same as the direction of the connecting rod 6, and the middle section of the wrench 2 is located below the connecting rod 6. One hand can hold the connecting rod 6 and the wrench 2 at the same time. The two ends of the wrench 2 are fixedly connected to the two limiting rings respectively. Figure 4 and Figure 5The wrench 2 is pulled so that the movable part 1 can rotate relative to the connecting rod 6 along the sleeve axis. The other end of the connecting rod 6 is welded to the center of the crossbar of the fixed part 4. The limiting part 3 is a cylinder with the diameter at both ends smaller than the diameter of the middle section. The limiting part 3 is welded parallel to the lower part of the outside of the sleeve. The length of the middle section of the limiting part 3 is the same as that of the sleeve so that the smaller diameter sections at both ends are aligned with the limiting ring, thereby limiting the wrench 2 fixed on the limiting ring. The movable part, the fixed part and the connecting rod form a frame structure with four vertical rods. When the two ends of the wrench 2 are respectively in contact with the smaller diameter sections at both ends of the limiting part, the four vertical rods are exactly parallel to each other. At this time, the axis of the four vertical rods is aligned with the center of the four holes of the casting core. The limiting rubber sleeve 5 is sleeved at the contact position between the four vertical rods and the casting core. The limiting rubber sleeve 5 is a frustum-shaped structure that is narrow at the bottom and wide at the top. The diameter of the lower end of the limiting rubber sleeve 5 is smaller than the hole diameter of the casting core. The limiting rubber sleeve is made of rubber.
[0021] In the process where manual core setting is required, such as Figure 2 As shown, firstly, the sand core is clamped by the fixture. The movable part 1 and its wrench 2 are limited by the limiting block 3 under their own weight, making the vertical rods vertical. At this time, the four vertical rods with limiting rubber sleeves 5 are aligned with the four holes of the sand core and inserted into them. The limiting rubber sleeves 5 are locked at the end face of the holes. Then, the connecting rod 6 and the wrench 2 are held simultaneously with one hand, as shown... Figure 5 As shown, rotating the wrench 2 toward the connecting rod 6 causes the vertical rod of the movable part 1 to rotate toward the inside of the clamp, while the vertical rod of the fixed part 4 on the other side remains stationary, thus clamping the sand core. After the sand core is extracted and placed in the designated position, the wrench 2 is released, and the wrench 2 returns to its original position under gravity, thus releasing the sand core.
[0022] The clamping position of this utility model utilizes the four holes on the top surface of the sand core instead of clamping the perimeter of the sand core, thus preventing interference with adjacent structures when placing the sand core.
[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
