Description

Technical Field

[0001] This utility model relates to a shot blasting machine, and more particularly to a limiting mechanism for a hook-type shot blasting machine used for casting processing. Background Technology

[0002] Hook-type shot blasting machines are widely used in the surface cleaning or strengthening processes of medium and small castings and forgings in industries such as casting, construction, chemical, motor, and machine tools. The workpiece is hoisted into the shot blasting chamber by a hook, and shot is thrown onto the surface of the workpiece by a shot blaster, so that the surface of the workpiece reaches a certain roughness, making the workpiece more aesthetically pleasing, or changing the compressive stress of the workpiece to improve its life.

[0003] When processing small and medium-sized workpieces, the operation process of a hook-type shot blasting machine involves first hanging the workpiece on a hanger, then suspending the entire hanger from the hook, and finally sending them into the shot blasting chamber for processing via the hook system. However, in actual operation, due to the variety of workpiece types and the inability of workers to precisely control the arrangement of the hangers, it is difficult to ensure that the overall weight of the hanger is evenly distributed after suspension, and large local weight deviations are very likely to occur. In addition, the hook and hanger are connected by an abutting hook, which cannot provide effective limiting force for the hanger. Therefore, the hanger is prone to misalignment after suspension. This not only causes collisions between the hanger and the shot blasting chamber, and between the hook and the chamber, but also seriously affects the stability of the hanger's rotation, thus creating a significant safety hazard. In view of the above problems, this improvement has emerged. Utility Model Content

[0004] The purpose of this invention is to provide a limiting mechanism for a hook-type shot blasting machine used for casting processing. This limiting mechanism can improve the rotational stability of the hanger, thereby avoiding potential safety hazards and ensuring safe and stable operation of the processing process.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a limiting mechanism for a hook-type shot blasting machine for casting processing, comprising a cleaning chamber and a hanging frame, wherein a docking groove is formed on the cleaning chamber to connect the opening of the cleaning chamber and allow the hanging frame to pass through, and a processing position is formed on the docking groove; when the hanging frame is in the processing position, a limiting component is provided in the cleaning chamber near the lower end of the hanging frame to cooperate with the hanging frame and to limit the horizontal movement of the hanging frame; the limiting component has a limiting rotation state and a non-limiting state; the movement of the hanging frame is used to control the limiting component to switch between the limiting rotation state and the non-limiting state.

[0006] By adopting the above technical solution, the hanger is suspended from the hook of the shot blasting machine's hook system, and the workpiece to be processed is then suspended from the hanger. The hook system guides the hanger into the cleaning chamber via a docking chute. When the hanger moves to the processing position within the docking chute, the hook system controls the hanger's movement to switch the set limiting components to a limiting rotation state, thereby limiting the horizontal rotation of the hanger. This design effectively limits the rotating hanger, preventing excessive rotation and deviation, thus improving the hanger's rotational stability, avoiding safety hazards, and ensuring safe and stable operation of the processing process.

[0007] The limiting component is further configured such that: the limiting member includes a limiting block fixedly mounted on the hanger and a limiting groove disposed in the cleaning chamber and having an upper opening for the limiting block to be inserted into, wherein the limiting block is inserted into the limiting groove to form a rotational fit.

[0008] By adopting the above technical solution, the hook system controls the hanger to move downward so that the limiting block is inserted into the limiting groove. In this way, the hanger is rotated and limited in the horizontal direction, thereby improving the rotational stability of the hanger.

[0009] The cleaning chamber is further configured such that one end of the cleaning chamber opening is connected to the bottom of the limiting groove, the other end of the guiding groove is connected to the bottom of the limiting groove, the guiding groove is located below the limiting groove, the limiting groove is provided with a notch that connects to the outside and the side wall of the limiting groove and allows the hanger to pass through, and the notch is located directly above the guiding groove.

[0010] By adopting the above technical solution, as the bracket enters the cleaning chamber through the docking chute, the lower end of the bracket slides along the guide chute, thereby guiding the limiting block to move more accurately to the top of the limiting groove, so that the limiting block can be inserted into the limiting groove more smoothly.

[0011] The limiting block is further configured such that the bottom of the limiting block has a guide protrusion that extends downward and gradually narrows.

[0012] By adopting the above technical solution, the setting of the guide protrusion can further guide the limit block inserted into the limit groove, thereby improving the smoothness of operation and the probability of success.

[0013] A further configuration is provided: the hanger is provided with a dust cover for covering the opening of the limiting groove at the position above the limiting block, and when the limiting block is inserted into the limiting groove, the edge height of the dust cover is lower than the opening height of the limiting groove.

[0014] By adopting the above technical solution, the dust cover is designed to reduce the probability of particles entering the limiting groove, thereby ensuring smooth insertion operations and improving the long-term reliability of the structure.

[0015] The cleaning chamber is further configured such that: a door is rotatably mounted on the cleaning chamber for opening and closing the cleaning chamber opening; a dustproof plate is slidably mounted on the cleaning chamber for covering the docking groove except for the processing position; a linkage component that works with the door is connected to the dustproof plate; when the door is in the open state, the linkage component controls the dustproof plate not to cover the docking groove; when the door is in the closed state, the linkage component controls the dustproof plate to cover the docking groove.

[0016] By adopting the above technical solution, the linkage between the door and the dustproof panel is achieved through the set linkage components. This eliminates the need for additional control structures to control the dustproof panel, thereby reducing the failure rate and cost. Furthermore, the dustproof panel effectively reduces dust generation during processing without interfering with the normal movement of the hanger, thus improving the workshop's processing environment.

[0017] The linkage assembly is further configured as follows: the linkage assembly includes a linkage arm with two ends and rotatably disposed in the cleaning chamber, a linkage waist-shaped hole disposed at one end of the linkage arm, a linkage column that moves with the dustproof plate and extends into the linkage waist-shaped hole, and a reset spring connected to the dustproof plate. The other end of the linkage arm relative to the linkage waist-shaped hole extends out of the cleaning chamber and intersects with the movement path of the door.

[0018] By adopting the above technical solution, when the door is in the open state, it does not abut against the linkage arm. The set return spring drives the dustproof plate away from the docking groove, so that it does not cover the docking groove. When the door closes the cleaning chamber opening, the door abuts against the linkage arm, and through the cooperation of the linkage waist-shaped hole and the linkage column, it drives the dustproof plate to move towards the docking groove side to cover the docking groove.

[0019] In summary, this utility model has the following beneficial effects: it can improve the rotational stability of the hanging bracket, thereby avoiding potential safety hazards and ensuring safe and stable operation of the processing process. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] refer to Figures 1 to 4 A limiting mechanism for a hook-type shot blasting machine for casting processing includes a cleaning chamber 1 and a hanger 2. The cleaning chamber 1 has a connecting groove 3 that connects to the opening of the cleaning chamber 1 and allows the hanger 2 to pass through. A processing position 4 is formed on the connecting groove 3. When the hanger 2 is in the processing position 4, a limiting member 5 is provided in the cleaning chamber 1 near the lower end of the hanger 2 to cooperate with the hanger 2 and restrict the horizontal movement of the hanger 2. The limiting member 5 has a limiting rotation state and a non-limiting state. The lifting movement of the hanger 2 controls the switching of the limiting member 5 between the limiting rotation state and the non-limiting state.

[0024] The limiting component 5 includes a limiting block 51 fixedly mounted on the hanger 2 and a limiting groove 52 opened in the cleaning chamber 1, having an upper opening for the limiting block 51 to be inserted into. The limiting block 51 is inserted into the limiting groove 52 to form a rotational fit. A guide groove 15 is opened in the cleaning chamber 1, with one end connected to the opening of the cleaning chamber 1 and the other end connected to the bottom of the limiting groove 52. The guide groove 15 is located below the limiting groove 52. The limiting groove 52 has a notch 6 that connects to the outside and the side wall of the limiting groove 52 and allows the hanger 2 to pass through. The notch 6 is located directly above the guide groove 15 and is opened in the cleaning chamber 1.

[0025] The bottom of the limiting block 51 is integrally formed with a guide protrusion 7 that extends downward and gradually narrows. The bracket 2 is fixedly provided with a dust cover 8 for covering the opening of the limiting groove 52 at a position above the limiting block 51. When the limiting block 51 is inserted into the limiting groove 52, the edge height of the dust cover 8 is lower than the opening height of the limiting groove 52.

[0026] The cleaning chamber 1 is equipped with a rotating door 9 for opening and closing the chamber 1. The door 9 has two panels. A dustproof plate 10 is slidably installed on the top of the inner wall of the cleaning chamber 1 to cover the docking groove 3 except for the processing position 4. The dustproof plate 10 is connected to a linkage component that works with the door 9. When the door 9 is open, the linkage component controls the dustproof plate 10 not to cover the docking groove 3. When the door 9 is closed, the linkage component controls the dustproof plate 10 to cover the docking groove 3.

[0027] The linkage assembly includes a linkage arm 11 with two ends, rotatably mounted on the inner wall of the cleaning chamber 1 near the top; a linkage slot 12 at one end of the linkage arm 11; a linkage post 13 fixedly mounted on the dustproof plate 10 and extending into the linkage slot 12; and a return spring 14 connected to the dustproof plate 10. The other end of the linkage arm 11, relative to the linkage slot 12, extends out of the cleaning chamber 1 and intersects the movement path of the door 9. That is, when the door 9 closes the opening of the cleaning chamber 1, the door 9 abuts against the linkage arm 11, causing the linkage arm 11 to rotate, which in turn controls the dustproof plate 10 to stretch the return spring 14 towards the docking groove 3. The two ends of the return spring 14 are fixedly connected to the dustproof plate 10 and the inner wall of the cleaning chamber 1, respectively. The return spring 14 is a tension spring.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
