DETAILED DESCRIPTION

[0035] 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.

[0036] Example 1:

[0037] like Figures 1 to 6 As shown, Embodiment 1 of this utility model provides a shot blasting device for processing the surface of a brake disc. This device mainly includes a shot blasting machine body 1 and a shot blasting support. The shot blasting machine body 1 can be an existing shot blasting machine on the market. Existing shot blasting machine bodies 1 generally have a shot blasting chamber 2 inside. In this utility model, a positioning seat 3 is rotatably installed inside the shot blasting chamber 2 for supporting and rotating the shot blasting support. The shot blasting support can be locked onto the positioning seat 3. The positioning seat 3 achieves rotatable installation within the shot blasting chamber 2 through a rotary support. Figure 2 and Figure 3 As shown, the shot blasting support is designed to stably hold multiple brake discs. The shot blasting support consists of two parallel limiting frames, defined as the first limiting frame 4 and the second limiting frame 5. Each limiting frame has multiple parallel crossbars 23 fixed to it, perpendicular to the limiting frame. Each crossbar 23 has multiple parallel inserts 6 hinged to it. These inserts 6 can be precisely inserted into the slits on the upper and lower sides of the brake disc, achieving stable fixation of the brake disc during the shot blasting process.

[0038] To achieve flexible adjustment of the spacing between the upper and lower sets of insertion rods 6, thereby stably inserting the insertion rods 6 into the slit, this device is designed with a limit adjustment mechanism, including at least two parallel telescopic members 7. The two ends of these telescopic members 7 are respectively hinged to the first limit frame 4 and the second limit frame 5, thus forming a parallelogram structure with the two telescopic members 7 and the two limit frames. Figure 3 and Figure 4 As shown, a linkage plate 22 is hinged between the two telescopic components 7, and the linkage plate 22 is also hinged to the insertion rod 6. The linkage plate 22 is parallel to the limiting frame. Figure 4 When viewed from the reference point, as shown by the dashed lines, the linkage plate 22, the limiting frame, the telescopic component 7, and the insert rod 6 also form a parallelogram structure. Thus, when the angle between one of the telescopic components 7 and the limiting frame changes, the angle between the insert rod 6 and the limiting frame also changes synchronously, and the distance between the corresponding sets of insert rods 6 on the first limiting frame 4 and the second limiting frame 5 remains unchanged, thereby maintaining the limiting state of the brake disc when changing its tilt angle.

[0039] like Figures 4 to 6As shown in the figure, each telescopic piece 7 is composed of a guide sleeve 8 and a movable sleeve 9, one end of the guide sleeve 8 is hinged on the first limiting frame 4, and one end of the movable sleeve 9 is hinged on the second limiting frame 5, and the other end of the movable sleeve 9 is slidably inserted into the guide sleeve 8. In order to drive the movement of the movable sleeve 9 in the guide sleeve 8, so as to adjust the distance between the two limiting frames, so that the plug rod 6 can be pulled out of or inserted into the slit of the brake disc, the scheme designs a first lead screw 10, which is rotatably installed in the movable sleeve 9 and is in threaded cooperation with the guide sleeve 8. When the first lead screw 10 is driven to rotate, the movable sleeve 9 will move linearly along the guide sleeve 8, thereby adjusting the distance between the two limiting frames to adapt to brake discs of different sizes, while realizing the fixation of the brake disc.

[0040] In order to realize the fine adjustment of the inclination angle of the telescopic piece 7 and change the impact angle of the projectile on the brake disc, an adjusting structure is designed. As shown in the figure, Figure 3 The adjusting structure includes a limiting plate 19 fixed on the first limiting frame 4, and a plurality of positioning holes 20 are formed in the limiting plate 19 and arranged in a ring around the hinge shaft between the telescopic piece 7 and the first limiting frame 4. A limiting hole is formed in the telescopic piece 7, and by inserting a pin rod 21, the pin rod 21 passes through different positions of the limiting hole and the positioning hole 20, so that the inclination angle of the telescopic piece 7 can be adjusted, thereby further optimizing the position and posture of the brake disc during the shot blasting process.

[0041] Embodiment two:

[0042] On the basis of embodiment one, in order to simplify the adjustment process of the two telescopic pieces 7 and make it easier to adjust, the utility model designs a composite transmission system which can rotate the two first lead screws 10 at the same time. Specifically, the composite transmission system includes an adjusting rod 11 and two parallel transmission rods 12, and the adjusting rod 11 and the transmission rod 12 are both rotatably installed on the second limiting frame 5, and the two transmission rods 12 are located on both sides of the adjusting rod 11.

[0043] As shown in the figure, Figure 6 The adjusting rod 11 drives the transmission rod 12 to rotate through the first transmission mechanism, i.e. the meshing of the first bevel gear 13 and the second bevel gear 14, the first bevel gear 13 is fixed on the adjusting rod 11, and the second bevel gear 14 is fixed on the transmission rod 12, and rotating the adjusting rod 11 can simultaneously drive the two transmission rods 12 to rotate. As shown in the figure, Figure 5As shown, the transmission rod 12 then drives the first lead screw 10 to rotate through the second transmission mechanism, i.e. a third bevel gear 15 fixed on the hinged shaft of the second limiting frame 5 and the movable sleeve 9, a fourth bevel gear 16 fixed on the transmission rod 12 and a fifth bevel gear 17 fixed on the first lead screw 10. When the transmission rod 12 rotates, the fourth bevel gear 16 drives the third bevel gear 15 to rotate, and the third bevel gear 15 can drive the fifth bevel gear 17 to rotate, so that the transmission rod 12 can drive the first lead screw 10 to rotate. When the angle between the second limiting frame 5 and the movable sleeve 9 changes, the transmission relationship can still be maintained. This design allows the operator to quickly and accurately adjust the overall height of the two telescopic members 7 by simply rotating the adjusting rod 11.

[0044] Embodiment three:

[0045] In order to ensure the safety and stability of the transmission system, a protective cover 18 is installed on the second limiting frame 5, which can effectively cover the first transmission mechanism, the second transmission mechanism and the transmission rod 12, prevent the projectiles from entering, and prevent the bevel gears from being stuck.

[0046] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
