[0022] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0023] Reference Figure 1 - Figure 4 A reciprocating lifting sandblasting machine comprises a box body 1 and a box door 2 located at the front end of the box body 1, a support platform 3 is arranged inside the box body 1, a clamping and rotating mechanism 4 for clamping and rotating a workpiece is arranged on the support platform 3, a sliding frame 5 for driving the workpiece to slide is arranged inside the box body 1, an angle adjustment mechanism 6 for driving the clamping and rotating mechanism 4 to change the single-sided clamping angle is arranged between the sliding frame 5 and the support platform 3, and a locking mechanism 7 for locking the box door 2 and the sliding frame 5 on the box body 1 is arranged between the box body 1 and the box door 2 and the sliding frame 5.

[0024] Reference Figure 4 The angle adjustment mechanism 6 includes a rotating seat 61 fixed to the bottom of the support platform 3 and rotating inside the sliding frame 5, a gear 62 distributed on the outer ring of the rotating seat 61, and a tooth block 63 arranged inside the sliding frame 5 and engageable with the gear 62. A lever 64 is fixed to the upper end of the tooth block 63, and a spring 65 is arranged between one side of the tooth block 63 and the sliding frame 5. The tooth block 63 is engaged with the gear 62 through the spring 65. The lever 64 protrudes from the upper end of the sliding frame 5 and a movable groove for the lever 64 is opened in the sliding frame 5. The angle adjustment mechanism 6 can facilitate the stable clamping of workpieces with non-parallel ends, and has better adaptability and practicality.

[0025] Reference Figure 1 - Figure 4 The box body 1 and the sliding frame 5 are connected by means of a slide rail and a slider. The sliding frame 5 is provided with a limit block 51, and the box body 1 is provided with a limit groove that cooperates with the limit block 51. The clamping position is changed by sliding the sliding frame 5, thereby facilitating the clamping of the workpiece and improving the convenience of clamping and taking materials.

[0026] Reference Figure 5 The locking mechanism 7 includes a movable seat 71 fixed at the front end of the bottom of the box body 1 and a movable plate 72 vertically sliding in the movable seat 71, as well as a locking cylinder 73 fixed at the bottom of the movable seat 71 and a locking plate 74 fixed at the upper end of the movable plate 72. The locking mechanism 7 can synchronously lock the sliding frame 5 and the box door 2 with high reliability.

[0027] Reference Figure 4 - Figure 5 The front end of the sliding frame 5 and the front end of the bottom of the box door 2 are both provided with an extended strip plate, and a penetrating locking hole 75 is opened on the strip plate. The locking plate 74 is connected and disengaged with the locking hole 75 through the locking cylinder 73. The locking holes 75 provided on the box door 2 and the sliding frame 5 are matched with the locking plate 74 for better linkage.

[0028] Reference Figure 4 The clamping rotation mechanism 4 includes a rotating motor 41 fixed to the outside of the support platform 3, a clamping cylinder 42 fixed to the output end of the rotating motor 41, and a clamping plate 43 fixed to the output end of the clamping cylinder 42. The rotating motors 41 at both ends can facilitate the flipping of the workpiece while ensuring the flipping accuracy. The clamping cylinder 42 can clamp the workpiece conveniently and stably with high reliability. In order to increase friction and avoid wear on the workpiece, an anti-slip part can be set at the front end of the clamping plate 43.

[0029] Working principle: when clamping the workpiece, the sliding frame 5 is pulled outward along the slide rail, and the sliding range is limited under the action of the limit block 51. At this time, the clamping and rotating mechanism 4 is located at the front end of the box body 1, and is not affected by the entire frame of the box body 1 during clamping. The support table 3 and the clamping and rotating mechanism 4 are adjusted through the angle adjustment mechanism 6 according to the angle of the clamping surface of the workpiece. The clamping cylinder 42 extends out to clamp the workpiece through the two clamping plates 43, and the sliding frame 5 is slid back into the box body 1. The box door 2 is closed, and the locking cylinder 73 pushes the movable plate 72 and the locking plate 74 upward. The movable plate 72 moves upward inside the movable seat 71. At this time, the locking plate 74 is simultaneously engaged with the locking holes 75 on the sliding frame 5 and the box door 2, and sandblasting can be carried out. When one side is sandblasted and needs to be turned over, the rotating motor 41 is started to rotate to turn the workpiece;

[0030] The angle adjustment mechanism 6 is used as follows: the tooth block 63 is pulled outward by the lever 64, the spring 65 is compressed, the tooth block 63 is disengaged from the engagement with the rotating seat 61, and then the support platform 3 and the clamping rotating mechanism 4 are rotated, and the rotating seat 61 rotates in situ on the sliding frame 5 to ensure that the clamping plate 43 is parallel to the clamped surface. After the lever 64 is released, the spring 65 drives the tooth block 63 to engage with the corresponding position of the rotating seat 61, thereby realizing the adjustment and locking work.

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
