Description

Technical Field

[0001] This utility model relates to the field of limiting tooling technology, and more specifically to a limiting tooling for the maintenance of a casting machine. Background Technology

[0002] A casting machine is an industrial device that uses technology to melt metal into a liquid that meets certain requirements, pour it into a mold, and after cooling, solidification, and cleaning, obtain a casting with a predetermined shape, size, and properties. The casting machine boom is an important component of casting machinery, used to assist in the movement and positioning of the mold and the handling of castings during the casting process. The casting machine boom plays a crucial role in automated casting production. It not only improves production efficiency and safety but also enhances the quality and precision of the castings.

[0003] However, when the casting machine malfunctions and needs repair, operators need to enter the casting machine to carry out inspection and maintenance; however, the bent arm poses a safety risk of being pinched and injured when it moves backward, which affects the safety of the workers when inspecting and maintaining the equipment. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a limiting fixture for the maintenance of a casting machine. With the support of the adjusting rods at both ends of the main frame and the clamping parts, it can prevent the curved arm from accidentally retreating and causing injury, thereby effectively ensuring the safety of the operator and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limiting fixture for the maintenance of a casting machine, including a limiting component for positioning and supporting the crank arm of the casting machine;

[0006] The limiting component includes a main frame, both ends of which are provided with adjusting screws, and a mounting groove is provided on the side of the main frame corresponding to the adjusting screws, with the end of the adjusting screws near the main frame extending into the mounting groove.

[0007] The adjusting thread has an adjusting rod inside, and the adjusting rod extends to the outside of the end of the adjusting thread away from the main frame. A clamping member is installed at the end of the adjusting rod away from the adjusting thread. A locking cap is threaded to the outside of the adjusting rod. The locking cap extends into the adjusting thread at the end away from the clamping member, and the locking cap is threaded to the adjusting thread.

[0008] In a preferred embodiment, a groove is provided on the side of the clamping member away from the adjusting rod. A contact and a pressure sensor are installed inside the groove. The contact is located on the side of the pressure sensor away from the groove. The pressure sensor detects the pressure when the clamping member contacts the crank arm and transmits the detection to the controller, so that the controller can compare the subsequent pressure value changes of the pressure sensor.

[0009] In a preferred embodiment, a controller is installed on the top of the main frame, and audible and visual alarms are provided on both sides of the controller. The audible and visual alarms are installed on the top of the main frame. When the controller determines that the pressure value has changed, it activates the audible and visual alarms to issue an early warning, so as to inform the staff to stay away in time or to carry out timely maintenance.

[0010] In a preferred embodiment, the top of the main frame is provided with a handle, and the bottom ends of both ends of the handle are fixed to the top of the main frame. By connecting the handle to the main frame, the operator can hold the handle to operate the main frame, thereby improving the convenience of the operator in operating the column frame.

[0011] In a preferred embodiment, two sets of spaced-apart fasteners are installed on the exterior of the main frame; each set of fasteners includes a front clamp and a rear clamp, which are respectively installed on the front and rear sides of the main frame, with the front clamp positioned in front of the rear clamp. The cooperation of the front and rear clamps facilitates the installation of the main frame onto the rods on the casting machine, thereby ensuring the stability of the main frame.

[0012] In a preferred embodiment, an anti-slip sleeve is provided on the outer side of the top of the handle. The connection between the anti-slip sleeve and the handle can enhance the friction between the worker's hand and the handle, thereby preventing loosening and ensuring the stability of the worker during operation.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] By separating the locking cap and the adjusting screw, the clamping part on the adjusting rod can be pulled outward to support the crank arm. Then, by connecting the locking cap and the adjusting screw, the stability of the adjusting rod and the clamping part after adjustment can be ensured. Furthermore, the support of the adjusting rod and the clamping part can prevent the crank arm from accidentally moving backward and causing injury, thus effectively ensuring the safety of the operator.

[0015] The pressure sensor detects the pressure when the clamping part contacts the crank arm, and the controller records the data. If the pressure value of the pressure sensor changes abnormally, the controller will activate an audible and visual alarm to warn the staff to repair or move away in time, thereby enhancing the safety of this utility model.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figure 1-5 This utility model provides a limiting tooling for the maintenance of a casting machine, including a limiting component for positioning and supporting the crank arm of the casting machine;

[0024] like Figure 1 , 2 As shown in Figures 3 and 5, the limiting component includes a main frame 1. Both ends of the main frame 1 are provided with adjusting threads 2, and a mounting groove 3 is opened on the side of the main frame 1 corresponding to the adjusting threads 2. The end of the adjusting threads 2 near the main frame 1 extends into the mounting groove 3. An adjusting rod 4 is provided inside the adjusting threads 2, and the adjusting rod 4 extends to the outside of the end of the adjusting threads 2 away from the main frame 1. A clamping member 5 is installed on the end of the adjusting rod 4 away from the adjusting threads 2. A locking cap 6 is threadedly connected to the outside of the adjusting rod 4. The end of the locking cap 6 away from the clamping member 5 extends into the adjusting threads 2, and the locking cap 6 is threadedly connected to the adjusting threads 2.

[0025] Specifically, the crank arm is supported by the outward movement of the adjusting rods 4 at both ends of the main frame 1, and the adjusting rods 4 are fixed by the threaded connection between the locking cap 6 and the adjusting screw 2, so as to prevent the crank arm from moving backward and injuring the staff, and to ensure the safety of the staff during operation.

[0026] like Figure 4 As shown, a groove 7 is provided on the side of the clamping member 5 away from the adjusting rod 4. A contact member 8 and a pressure sensor 9 are installed inside the groove 7. The contact member 8 is located on the side of the pressure sensor 9 away from the groove 7. The pressure sensor 9 detects the pressure when the clamping member 5 contacts the crank arm and transmits the detection to the controller 10, so that the controller 10 can compare the subsequent pressure value changes of the pressure sensor 9.

[0027] like Figure 1 and 2 As shown, a controller 10 is installed on the top of the main frame 1, and an audible and visual alarm 11 is provided on both sides of the controller 10. The audible and visual alarm 11 is installed on the top of the main frame 1. When the controller 10 determines that the pressure value has changed, it activates the audible and visual alarm 11 to issue a warning and inform the staff to stay away or carry out timely maintenance.

[0028] like Figure 1 , 2 As shown in Figure 5, the top of the main frame 1 is provided with a handle 12. The bottom ends of both ends of the handle 12 are fixed to the top of the main frame 1. The connection between the handle 12 and the main frame 1 allows the operator to hold the handle 12 to operate the main frame 1, thereby improving the convenience of the operator to operate the column frame. The top of the handle 12 is covered with an anti-slip sleeve 15. The connection between the anti-slip sleeve 15 and the handle 12 can enhance the friction between the operator's hand and the handle 12, thereby preventing loosening and ensuring the stability of the operator during operation.

[0029] like Figure 1 , 2 As shown in Figure 5, two sets of spaced-apart fasteners are installed on the outside of the main frame 1; each set of fasteners includes a front clamp 13 and a rear clamp 14. The front clamp 13 and the rear clamp 14 are respectively installed on the front and rear sides of the main frame 1. The front clamp 13 is located in front of the rear clamp 14. Through the cooperation of the front clamp 13 and the rear clamp 14, it is convenient for the workers to install the main frame 1 onto the rods on the casting machine, thereby ensuring the stability of the main frame 1.

[0030] First, the operator uses the front clip 13 and the rear clip 14 to place the main frame 1 on the rod on the casting machine. Then, the locking cap 6 is rotated to separate from the adjusting screw 2, which makes it easier for the operator to pull the adjusting rod 4 outward and make the clamping part 5 on the adjusting rod 4 contact the curved arm on the casting machine.

[0031] After contact, the staff will then connect the locking cap 6 with the adjusting screw 2, which will achieve the effect of limiting and fixing the adjusting rod 4. The clamping parts 5 at both ends of the main frame 1 can support and limit the curved arm, thus ensuring the safety of the staff during maintenance and preventing accidental backward movement and injury.

[0032] Meanwhile, the pressure sensor 9 detects the pressure when the clamping part 5 contacts the crank arm, and the controller 10 records it. If the pressure value of the pressure sensor 9 changes abnormally, the controller 10 activates the audible and visual alarm 11 to issue a warning, and promptly informs the staff to inspect and maintain the utility model or to move away from danger, thereby enhancing the safety of the utility model.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
