Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically to a shot blasting machine blade that is easy to assemble and disassemble quickly. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. It can perform tasks such as sand removal, core removal, and cleaning of castings. The blades of the shot blasting machine, as one of its main components, are in constant contact with the high-speed shot. Currently, when installing blades, the dovetail mounting base at the lower end of the blade needs to be slidably engaged with the impeller, and the blades are arranged in a circumferential array within the impeller. A shot distribution wheel is fixed to the center of the impeller using hexagonal socket head cap screws, which helps to secure the blades.

[0003] For example, patent publication number CN223012889U discloses a shot blasting machine blade that is easy to assemble and disassemble. This blade solves the problems mentioned in the background technology, such as complex positioning structures, difficult maintenance in case of failure, and the waste of materials due to the blade being a single integrated structure, where sometimes even a small damage to the end requires replacing the entire blade. The blade body includes a blade main body with guide cavities on both sides. The blade main body includes several blade supports that are spliced ​​together internally and externally. The inner and outer end faces of the blade supports have a first splicing structure that cooperates with each other. The inner end of the blade main body is spliced ​​to the impeller fixing seat through a second splicing structure. The first splicing structure includes a locking block fixed to the inner end face of the blade support, and a first locking groove that cooperates with the locking block is embedded in the outer end face of the blade support. It is simple to operate, convenient to use, and suitable for various types of shot blasting machines.

[0004] While the existing equipment can facilitate the separation, disassembly, and replacement of blades, when a blade is damaged inside the impeller, the shot blasting machine needs to be disassembled one by one until the shot distribution wheel is removed. Then, the blade is pushed towards the center of the impeller to remove it. Therefore, the disassembly speed between the existing blade and the impeller is slow and the efficiency is low.

[0005] Therefore, we propose a shot blasting machine blade that is easy to assemble and disassemble quickly. Utility Model Content

[0006] One of the technical problems this application aims to solve is to improve the efficiency of blade disassembly.

[0007] To address the aforementioned technical problems, this application provides a shot blasting machine blade that is easy to assemble and disassemble quickly. The blade body comprises a plurality of blade support plates, the blade support plates being slidably engaged with each other, and further includes:

[0008] A connecting rod, used to connect multiple blade bodies;

[0009] The mounting base is fixedly installed at one end of the blade body. The mounting base has symmetrical sliding engagement limit blocks inside, and the mounting base is provided with a pusher for moving the limit blocks in opposite directions.

[0010] In some embodiments, a locking block is fixedly installed on the inner end face of the blade support plate, and a locking groove is formed on the outer end face of the blade support plate, wherein the locking block and the locking groove are slidably inserted into each other.

[0011] In some embodiments, the connecting rod extends through the blade support plate at one end of the blade body to the interior of the blade support plate at the other end of the blade body. One end of the connecting rod is provided with an external thread, and an internal threaded hole that engages with the external thread is provided in the blade support plate located on the mounting base.

[0012] In some embodiments, one end of the connecting rod is hexagonal.

[0013] In some embodiments, the pusher includes a T-shaped carriage, and the mounting base has a T-shaped groove inside, with the T-shaped carriage and the T-shaped groove slidingly engaging with each other.

[0014] In some embodiments, each of the limiting blocks is rotatably mounted with a pusher frame via a connecting column, and one end of the pusher frame is rotatably mounted on the T-shaped slide.

[0015] In some embodiments, a positioning rod is rotatably mounted on one end of the T-shaped carriage, a positioning screw sleeve is rotatably mounted on one end of the positioning rod, and a threaded sleeve with internal threads is fixedly mounted on the mounting base.

[0016] This utility model has at least the following beneficial effects: 1. When a certain part of the blade body is severely damaged, the device can replace a certain blade support plate by unscrewing the connecting rod, and the replacement speed is fast and the device is highly practical.

[0017] 2. After the mounting base is installed onto the impeller of the shot blasting machine, the limiting block can be retracted into the mounting base by the set pusher, so that the blade body can be directly pulled out from the sliding groove set in the impeller, reducing the tedious disassembly process of the shot blasting machine and improving disassembly efficiency.

[0026] 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.

[0027] Example 1: Please refer to Figure 1-7 This utility model provides a technical solution: a shot blasting machine blade that is easy to assemble and disassemble quickly, comprising a blade body 1 composed of multiple blade support plates 101, the blade support plates 101 being slidably engaged with each other, and further comprising:

[0028] Connecting rod 2, used to connect multiple blade bodies 1;

[0029] Mounting base 3 is fixedly installed at the bottom of one end of blade body 1. Limiting blocks 4 are symmetrically slidably engaged inside the mounting base 3. Pushing components 5 are provided inside the mounting base 3 to make the limiting blocks 4 move towards each other.

[0030] Example 2: A locking block 6 is fixedly installed on the inner end face of the blade support plate 101, and a locking groove 7 is opened on the outer end face of the blade support plate 101. The locking block 6 and the locking groove 7 are slidably inserted into each other. The connecting rod 2 extends through the blade support plate 101 at one end of the blade body 1 to the inside of the blade support plate 101 at the other end of the blade body 1. One end of the connecting rod 2 is provided with an external thread 8. The blade support plate 101 located on the mounting base 3 is provided with an internal thread hole that meshes with the external thread 8, so as to facilitate the sliding locking of multiple blade support plates 101. Thus, after a certain blade support plate 101 is worn, the blade support plate 101 can be replaced. Moreover, multiple blade support plates 101 can be connected through the connecting rod 2. One end of the connecting rod 2 is provided with an internal hexagonal groove, so that the operator can easily turn the connecting rod 2 with a hexagonal wrench.

[0031] Example 3: The pusher 5 includes a T-shaped slide 501. A T-shaped groove 502 is provided inside the mounting base 3. The T-shaped slide 501 and the T-shaped groove 502 are slidably engaged with each other. A pusher 504 is rotatably mounted on each of the limiting blocks 4 via a connecting column 503. One end of the pusher 504 is rotatably mounted on the T-shaped slide 501. A positioning rod 505 is rotatably mounted on one end of the T-shaped slide 501. A positioning screw sleeve 506 is rotatably mounted on one end of the positioning rod 505. A threaded sleeve 507 with internal threads is fixedly mounted on the mounting base 3. The positioning screw sleeve 506 is screwed into the threaded sleeve 507. It should be noted that the blade body 1 is installed inside the impeller (not shown in the figure). Because a slot is provided inside the impeller, in the normal state, the limiting block 4 is... Extending from both sides of the mounting base 3, the limiting block 4 engages with the slot inside the impeller. When the blade body 1 needs to be disassembled directly, the operator first needs to unscrew the positioning screw sleeve 506 out of the threaded sleeve 507, which is equivalent to releasing the positioning of the limiting block 4. Then, the operator needs to pull the positioning rod 505 (the positioning rod 505 must be a rigid material rod). At this time, the positioning rod 505 drives the T-shaped slide 501 to move in the T-shaped slide groove 502, and then drives the push frame 504 to move. At this time, the included angle between the two push frames 504 becomes smaller, and the limiting block 4 begins to gradually approach until it moves into the mounting base 3, which makes it easier for the operator to pull the blade body 1 out of the impeller as a whole, thus improving the replacement efficiency of the blade body 1.
