Description

Technical Field

[0001] The utility model relates to the technical field of hangers for shot blasting machines, in particular to a built-in hanger for shot blasting machines. Background Art

[0002] Shot blasting machine, also known as sandblasting machine, sandblasting machine, is a casting equipment that uses high-speed projectiles thrown by the shot blaster to clean or strengthen the surface of castings. According to the structure of the casting carrier, it can be divided into drum type, chain plate type, hanging type shot blasting machine, etc. Its grinding methods include centrifugal grinding, water eddy current grinding, rotary grinding, etc. It is first used in the foundry industry to remove sand and oxide scale on the surface of cast steel and cast iron parts.

[0003] Some existing shot blasting machines use hoists to transport castings to the inside of the shot blasting machine and clean the surface of the castings. However, the hoists inside the shot blasting machine generally lift the castings by means of chains and hooks. This type of hoist has requirements for the type of castings. It is difficult to complete the lifting function when encountering irregular castings or round castings with smoother surfaces. Specific hoists need to be replaced for lifting. The replacement process is cumbersome and will waste a certain amount of time. Utility Model Content

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 5 As shown, the built-in hanger of the shot blasting machine in this embodiment includes a connecting rod assembly 1, the upper end of the connecting rod assembly 1 is connected to the internal conveying structure of the shot blasting machine, and the internal structure of the shot blasting machine is the prior art and will not be described in detail. A horizontal plate 2 is installed at the lower end of the connecting rod assembly 1, and the horizontal plate 2 has a certain length to be suitable for most casting lengths. Two movable connecting rods 3 are symmetrically installed on the left and right sides of the lower end of the horizontal plate 2. The two movable connecting rods 3 can move synchronously toward or oppositely at the lower end of the horizontal plate 2, and a second driving device 5 is installed at the lower end of the movable connecting rod 3. The second driving device 5 is a servo motor commonly found on the market. The output end below the second driving device 5 is connected to a triangular clamp 4 through a second rotating shaft 6, and the second rotating shaft 6 and the clamp 4 can be driven to rotate by the second driving device 5. The three surfaces of the clamp 4 are respectively set to an outer arc surface 7, an inner arc surface 8 and a straight surface 9, as shown Figure 3As shown, the three surfaces of the clamp 4 are respectively an outer arc surface 7 protruding outward, an inner arc surface 8 recessed inward, and a straight surface 9. The three surfaces of the two clamps 4 are used in conjunction with each other to be suitable for most types of castings of different sizes and surfaces, which to a certain extent avoids the need to replace the sling when clamping different types of castings.

[0024] Specifically, the connecting rod assembly 1 includes a telescopic rod 101, a first driving device 102 and a first rotating shaft 103. The first driving device 102 is installed at the lower end of the telescopic rod 101, and the first rotating shaft 103 is installed at the lower end of the first driving device 102. The lower end of the first rotating shaft 103 is connected to the center position of the upper end of the cross plate 2. The first driving device 102 can drive the first rotating shaft 103 and the cross plate 2 to rotate, and then the direction of the cross plate 2 can be adjusted according to the needs of the user, thereby enhancing the applicability of the device. The first driving device 102 is a servo motor commonly found on the market.

[0025] Furthermore, a groove 11 is opened at the lower end of the horizontal plate 2, and a forward and reverse threaded screw rod 10 is rotatably connected inside the groove 11. One end of the forward and reverse threaded screw rod 10 is connected to a driving device, which is a common servo motor on the market. The driving device drives the forward and reverse threaded screw rod 10 to rotate inside the groove 11, and the driving device is installed inside the horizontal plate 2.

[0026] Furthermore, the upper ends of the two movable connecting rods 3 are symmetrically installed on the left and right sides of the surface of the forward and reverse threaded screw 10, and the movable connecting rods 3 are threadedly connected to the forward and reverse threaded screw 10. When the forward and reverse threaded screw 10 rotates, the two movable connecting rods 3 will move synchronously toward or oppositely along the length direction of the forward and reverse threaded screw 10, and the specific movement method is determined according to the rotation direction of the forward and reverse threaded screw 10.

[0027] Furthermore, the size of the clamp 4 is larger than the size of the second rotating shaft 6. By setting the clamp 4 larger than the second rotating shaft 6, as shown in FIG. Figure 5 As shown, when encountering an irregular or regular casting with a through hole, two clamps 4 can be inserted through one through hole at the same time, and the two second rotating shafts 6 can be in contact with the inner wall of the through hole. At this time, the larger clamp 4 will support the casting from below. At this time, the casting will have good stability, thereby enhancing the applicability of the sling.

[0028] Furthermore, a chain 12 is installed at the lower end of the clamp 4, and a hook 13 is connected to the lower end of the chain 12. When encountering a long strip casting with a through hole, the two hooks 13 can be hung on the front and back sides of the casting respectively, and the lifting of the casting will be more convenient and quick.

[0029] The method of using this embodiment is as follows: a cross plate 2 is installed at the lower end of the connecting rod assembly 1, and a movable connecting rod 3 is symmetrically installed on the left and right sides of the lower end of the cross plate 2, and a clamp 4 is installed at the lower end of the movable connecting rod 3. The three surfaces of the clamp 4 are respectively an outer arc surface 7 protruding outward, an inner arc surface 8 recessed inward, and a straight surface 9. When clamping a cylindrical type casting, the two inner arc surfaces 8 can be clamped on both sides of the outer surface of the cylinder to apply pressure inward for clamping. When clamping a circular ring type casting, the two outer arc surfaces 7 can be clamped on both sides of the inner wall surface of the circular ring to apply pressure outward for clamping. When clamping an irregular type of casting, the three surfaces of the two clamps 4 can be used in coordination with each other to be suitable for most types of castings of different sizes and different surfaces, which to a certain extent avoids the need to replace the sling when clamping different types of castings.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
