This method has a small number of shot blasting times and a long time depending on the size of the warehouse, which cannot meet the needs of current automated machinery production. Utility Model Content

[0003] The technical problem to be solved by the utility model is: how to design a shot blasting and rust removal device for a drive axle housing to reduce the number of repeated movements of the user's wrist or arm.

[0004] The technical solution of the utility model is specifically as follows:

[0005] A shot blasting and rust removal device for a drive axle housing comprises a frame, a circular transmission chain is provided on the frame, a sling is fixed on the transmission chain, a sealed shot blasting chamber and a shot blasting machine are provided below the frame, and the entrance of the shot blasting machine is located in the shot blasting chamber; the shot blasting chamber is provided with a front door and a rear door that automatically open and close in the entry and exit directions of workpieces; a crack is provided on the roof of the shot blasting chamber, the crack is used for the sling to pass through, an outer cover is provided above the crack, two rubber strips are provided in the outer cover, and the gap between the two rubber strips is used for the sling to pass through.

[0006] The transmission chain includes a front chain and a rear chain. The shot blasting cabin is located below the rear chain. A crane is installed on the frame at the front chain. The crane is a KBK crane. Below the crane is the loading and unloading station.

[0007] The utility model comprises a control box, which is connected with a power mechanism of a front door and a rear door, a power mechanism of a transmission chain, a crane and a shot blasting machine.

[0008] There are multiple fixed hangers on the transmission chain, two of which can enter the shot blasting chamber at the same time, and one hanger can lift five workpieces.

[0009] Compared with the existing technology, the technical effect of the utility model is that the bridge housing of the utility model is suspended on the transmission chain, and multiple pieces can be shot blasted at a time, which greatly reduces the labor intensity of workers and improves production efficiency. It is also simple to operate and has low maintenance costs, making it suitable for large-scale quantitative production operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the present utility model.

[0011] Figure 2 for Figure 1 Schematic diagram of the right side.

[0012] Figure 3 yes Figure 2 An enlarged view of the shot blasting chamber roof. DETAILED DESCRIPTION

[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments thereof.

[0014] like Figure 1-3 A shot blasting and rust removal device for a drive axle housing includes a frame 10, a ring-shaped transmission chain 20 is provided on the frame 10, a sling 12 is fixed on the transmission chain 20, and the sling 12 is used to lift the workpiece.

[0015] A sealed shot blasting chamber 30 and a shot blasting machine are provided below the frame 10 , and an entrance of the shot blasting machine is located in the shot blasting chamber 30 .

[0016] The shot blasting chamber 30 is provided with a front door and a rear door (not shown) that are automatically opened and closed in the direction of entry and exit of the workpieces, respectively, for entry and exit of the workpieces.

[0017] A crack 32 is provided on the roof 31 of the shot blasting chamber 30 for the sling 12 to pass through. An outer cover 33 is provided above the crack 32 . Two rubber strips 34 are provided inside the outer cover 33 . The gap between the two rubber strips 34 is for the sling 12 to pass through.

[0018] To facilitate loading and unloading, the drive chain 20 includes a front chain 21 and a rear chain 22. The shot blasting chamber 30 is located below the rear chain 22. A crane 23 is installed on the frame 10 at the front chain 21. Crane 23 is a KBK crane. KBK is the abbreviation of KombiniertKran in German, which can be understood as a self-supporting modular crane or a light modular suspension crane. Below the crane 23 is the loading and unloading station 11.

[0019] For convenient control, it includes a control box 50, which connects the power mechanism (such as a motor) of the front door and the rear door, the power mechanism of the transmission chain 20, the crane 23, and the shot blasting machine.

[0020] In order to improve efficiency, a plurality of fixed slings 12 are arranged on the transmission chain 20 , wherein two slings 12 can enter the shot blasting chamber 30 at the same time, and one sling 12 can lift five workpieces.

[0021] Its working principle is:

[0022] like Figure 1-3 , including the following steps:

[0023] S1. Install the patented product on the ground 90, and close the front door and rear door of the shot blasting chamber 30.

[0024] S2. Transport the drive axle housing (hereinafter referred to as workpiece) to the loading and unloading station 11 , and use the crane 23 to hang the five workpieces on the first hanger 12 .

[0025] S3 , the transmission chain 20 rotates one unit and stops, the second sling 12 moves to the loading and unloading station 11 , and the crane 23 is used to hang the five workpieces on the second sling 12 .

[0026] S4, the transmission chain 20 rotates again until the first sling 12 is close to the front door of the shot blasting chamber 30.

[0027] S5. The front door of the shot blasting chamber 30 is opened, and the transmission chain 20 continues to rotate until the second sling 12 passes through the front door of the shot blasting chamber 30, and the front door of the shot blasting chamber 30 is closed.

[0028] S6, the transmission chain 20 stops, and the shot blasting machine performs shot blasting operation.

[0029] S7. After the shot blasting operation is completed, the rear door of the shot blasting cabin 30 is opened, and the transmission chain 20 continues to rotate until the second sling 12 passes through the rear door of the shot blasting cabin 30, and the rear door of the shot blasting cabin 30 is closed.

[0030] S8. When the first hoist 12 reaches the loading and unloading station 11, the transmission chain 20 stops and the crane 23 is used to unload the five workpieces.

[0031] S9, the transmission chain 20 rotates again. When the second sling 12 runs to the loading and unloading station 11, the transmission chain 20 stops and the crane 23 is used to unload the five workpieces.

[0032] It should be noted that when the sling 12 has not entered the shot blasting chamber 30, the two rubber strips 34 are pressed against each other to maintain the sealing of the shot blasting chamber 30; when the sling 12 enters the shot blasting chamber 30, the sling 12 forcibly enters between the two rubber strips 34 and passes through. After passing through, the two rubber strips 34 return to the state of being pressed against each other, thus solving the contradiction between the automation of the assembly line and the need to seal the shot blasting chamber 30.

[0033] The bridge housing of the utility model is suspended on the transmission chain and can shot blast 10 pieces at a time, which greatly reduces the labor intensity of workers and improves production efficiency. It is also simple to operate and has low maintenance costs, and is suitable for large-scale quantitative production operations. For other contents, please refer to the prior art.

[0034] The above description is only the preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
