Description

Technical Field

[0001] This utility model relates to the field of shell machining technology, specifically a workpiece auxiliary fixing device for shell machining. Background Technology

[0002] Shell molding refers to the process of using a shell molding machine (core shooter) to manufacture casting shells (or sand cores), which are then used as molds for metal pouring to ultimately obtain castings of the desired shape. Its core is the automated operation of the shell molding machine, which solidifies resin sand (such as phenolic resin sand, coated sand, etc.) in a heated core box to form a high-precision shell or sand core for subsequent casting production.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221755787U) discloses a workpiece lifting and moving auxiliary device for a shot blasting machine. The device includes a housing with support rods at both ends. Multiple support columns are located on the left side wall of the housing. A motor is detachably mounted on one side of the inner bottom wall of the housing. A lead screw is mounted at the output end of the motor, and the other end of the lead screw is fixedly connected to the inner wall of the housing via a bearing. A connecting seat is threaded onto the outer wall of the lead screw. The right end of the connecting seat extends out of the housing and is equipped with a connecting plate. A rectangular plate is mounted on the right side wall of the connecting plate, and a hydraulic telescopic rod is detachably mounted on the rectangular plate. This utility model employs a workpiece lifting auxiliary balancing device installed at the front of the shot blasting machine. The workpiece is clamped at both ends by a clamping mechanism and moves synchronously with the lifting machine, ensuring greater stability during workpiece movement and increasing the speed of workpiece lifting and movement, thereby improving the efficiency of the shot blasting process.

[0004] Although the aforementioned patent improves the positioning accuracy and stability during processing by setting up components such as lead screws, connecting seats, and rectangular plates, and by cooperating with each component, and uses a clamping mechanism to clamp the workpiece, and moves synchronously with the hoist to improve the speed and efficiency of workpiece movement, the workpiece often requires a large clamping force to ensure its stability during processing. However, this clamping process often causes some damage to the clamping point of the workpiece, which is very detrimental to improving the processing quality of the workpiece.

[0005] Therefore, this utility model provides an auxiliary workpiece fixing device for shell-shaped machining to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides an auxiliary workpiece fixing device for shell-shaped machining, such as... Figures 1-4 As shown, the workpiece auxiliary fixing device for shell-shaped machining includes a worktable 1, a support column is fixedly connected to the bottom end of the worktable 1, and a fixing component is provided inside the worktable 1.

[0027] The fixing component includes an adsorption plate 2 that is snapped onto the top of the workbench 1. The top of the adsorption plate 2 has adsorption holes 3, and there are several adsorption holes 3. The bottom of the workbench 1 is fixedly connected to a mounting box 4. An air pump 5 is installed at the bottom of the mounting box 4. The output end of the air pump 5 is fixedly connected to a vacuum generator 7 through an air pipe 6. The negative pressure end of the vacuum generator 7 is fixedly connected to an air box 9 through a negative pressure pipe 8. The air box 9 is hollow and its top is fixedly connected to the bottom of the adsorption plate 2. A positioning component is provided at the top of the workbench 1.

[0028] The fixed assembly also includes a cylinder 10 mounted on the top of the workbench 1. A universal ball 11 is installed at the output end of the cylinder 10, and a telescopic rod 12 is rotatably sleeved on the outer wall of the universal ball 11.

[0029] Two cylinders 10 are fixedly connected by a connecting pipe 13. The outer wall of the connecting pipe 13 is fixedly connected to the output end of the vacuum generator 7 through an air intake hose 14. An adjusting valve 15 is installed on the outer wall of the air intake hose 14.

[0030] Specifically, the support column provides sufficient support for the workbench 1, ensuring the stability of the workpiece during processing. The fixed components enhance the stability of the workpiece during processing through the cooperation of various parts, while preventing damage to the outer wall of the workpiece caused by the gripper, further improving the quality of workpiece processing. By starting the air pump 5, compressed air enters the vacuum generator 7. The vacuum generator 7 then uses the negative pressure suction at its negative pressure end, along with the negative pressure pipe 8 and air box 9, to quickly adsorb the workpiece on the adsorption plate 2, ensuring the stability of the workpiece during processing. When the workpiece is large, the regulating valve 15 can be rotated to allow gas to enter the connecting pipe 13 from the air supply end of the vacuum generator 7, causing the two cylinders 10 to move the telescopic rod 12. Rotating the telescopic rod 12 allows its inner wall to contact the workpiece, ensuring the workpiece's stability. When not in use, the rotation of the universal ball 11 ensures that the telescopic rod 12 does not affect workpiece processing. The regulating valve 15 can adjust the airflow to ensure that the clamping force is not excessive.

[0031] The positioning assembly includes a rotary seat 16 fixedly connected to the top of the worktable 1. A bidirectional lead screw 17 is rotatably connected to the inner wall of the rotary seat 16. A positioning sleeve 18 is threaded onto the outer wall of the bidirectional lead screw 17. A laser emitter 19 is installed on the inner wall of the positioning sleeve 18.

[0032] An electric push rod 20 is installed at the top of the worktable 1. A processing plate 21 is installed at the output end of the electric push rod 20. A processing device is installed inside the processing plate 21.

[0033] The bottom of the mounting box 4 is fixedly connected to a slide 22, and the inner wall of the slide 22 is slidably connected to a railing 23, and there are several railings 23.

[0034] Specifically, the positioning component can quickly position the workpiece. By rotating the bidirectional lead screw 17, the two positioning sleeves 18 on its outer wall are displaced. Since the positioning sleeves 18 are connected to the laser emitter 19, the laser can be used to quickly determine the workpiece processing position. At the same time, the height of the laser emitter 19 can prevent the positioning sleeves 18 from rotating on the outer wall of the lead screw, thus limiting their movement. The electric push rod 20 can make the processing plate 21 move vertically to adjust the position of the processing device. Multiple railings 23 can protect the equipment inside the mounting box 4 when not processing by sliding the multiple railings 23.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
