Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting jigs, in particular to a sandblasting jig for profiles. Background Art

[0002] A sandblasting jig is a tool specifically designed for sandblasting treatment. Sandblasting jigs are widely used in many fields such as aviation, automobiles, molds, handicrafts, etc., mainly for surface treatment of workpieces, such as removing oxide scales, rust, stains, etc., and improving the surface roughness and hardness of workpieces.

[0003] In the prior art, when using a sandblasting jig to sandblast a profile, since the profile is usually relatively long as a whole, when the profile is placed in the jig for sandblasting, the long profile will undergo a certain amount of sag deformation due to its own weight and gravity. For the sag deformation position of the profile, the sandblasting nozzle will not be able to accurately sandblast on the surface of the profile when passing by, affecting the sandblasting quality. Summary of the Utility Model

[0004] The utility model mainly provides a sandblasting jig for profiles that is convenient for calibrating the shape of the profile and ensuring accurate sandblasting.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A sandblasting jig for profiles, including a bottom plate and a profile body. A plurality of support rods are evenly and fixedly connected to the top of the bottom plate, and a top plate is fixedly connected between the upper end faces of the plurality of support rods; a support assembly, the support assembly is located outside the profile body, the support assembly includes a moving frame, both inner surfaces of the two sides of the moving frame are symmetrically and fixedly connected with connecting seats, a support shaft is rotatably connected to the inner surface of the connecting seat, a roller is fixedly connected to the outer surface of the support shaft, side blocks are fixedly connected to the outer surfaces of both sides of the moving frame, and jack holes are opened at the tops of the side blocks; a sandblasting assembly, the sandblasting assembly is fixedly connected to the bottom of the top plate, and the sandblasting assembly includes a top frame.

[0006] Compared with the prior art, the advantages and positive effects of the utility model are as follows.

[0007] 1. In the utility model, when sandblasting the profile body, while the moving plate moves to adjust the sandblasting position, since the moving plate and the moving frame at the bottom are in a splicing state, the moving plate will drive the moving frame to move accordingly. That is, while moving the sandblasting position, the moving frame is always outside the sandblasting position of the profile body. By using the moving frame, the shape of the profile body is calibrated, so that the sandblasting position of the profile body always maintains a stable shape, avoiding the influence of deformation due to sag on the accuracy of the sandblasting position when the profile body is clamped as a whole.

[0008] 2. In the present utility model, when sandblasting is performed after clamping and fixing the profile, the electric telescopic rod starts to extend and can be inserted into the jack, so that the moving frame and the moving plate are quickly in a spliced state, and the splicing operation of the moving plate and the moving frame is more convenient and fast.

[0014] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0015] Please refer to Figures 1-4 , the present utility model provides a technical solution: a sandblasting jig for profiles, including a bottom plate 1 and a profile body 4, a plurality of support rods 2 are uniformly and fixedly connected to the top of the bottom plate 1, and a top plate 3 is fixedly connected between the upper end surfaces of the plurality of support rods 2; a support assembly 5, the support assembly 5 is located outside the profile body 4, the support assembly 5 includes a moving frame 501, connecting seats 503 are symmetrically and fixedly connected to the inner surfaces of both sides of the moving frame 501, a support shaft 504 is rotatably connected to the inner surface of the connecting seat 503, a roller 505 is fixedly connected to the outer surface of the support shaft 504, side blocks 506 are fixedly connected to the outer surfaces of both sides of the moving frame 501, and a jack 507 is opened at the top of the side block 506; a sandblasting assembly 6, the sandblasting assembly 6 is fixedly connected to the bottom of the top plate 3, and the sandblasting assembly 6 includes a top frame 601.

[0016] As Figures 1-4 shown, the profile body 4 is located between two sets of rollers 505, and the outer surface of the rollers 505 is in contact with the outer surface of the profile body 4. When sandblasting the profile body 4, the moving frame 501 is sleeved on the outer side of the profile body 4. At this time, the middle profile body 4 is supported by the rollers 505 on both sides.

[0017] As Figures 1-4 shown, a motor 602 is fixedly connected to the outer surface of the top frame 601. The output end of the motor 602 penetrates through the top frame 601 and extends to the inside. The output end of the motor 602 is fixedly connected to a lead screw 603. The end face of the lead screw 603 is rotatably connected to the inner surface of the top frame 601. Starting the motor 602 drives the lead screw 603 to rotate. By the rotation of the lead screw 603, the sliding block 604 can be driven to move along the limiting rod 605.

[0018] As Figures 1-4 shown, a sliding block 604 is threadedly connected to the outer surface of the lead screw 603. A moving plate 606 is fixedly connected to the bottom of the sliding block 604. A sandblasting nozzle 608 is fixedly connected to the bottom of the moving plate 606. An avoidance groove 502 is formed at the top of the moving frame 501. The sandblasting nozzle 608 is matched with the position of the avoidance groove 502. By driving the moving plate 606 and the sandblasting nozzle 608 to move along with the sliding block 604, the covering sandblasting process of the profile body 4 is completed.

[0019] As Figures 1-4 shown, limiting rods 605 are symmetrically and fixedly connected to the inner surface of the top frame 601. The limiting rods 605 penetrate through the sliding block 604. The arrangement of the limiting rods 605 plays a role in supporting and limiting the movement of the sliding block 604.

[0020] As Figures 1-4 shown, electric telescopic rods 607 are symmetrically and fixedly connected to the bottom of the moving plate 606. The outer surface of the electric telescopic rods 607 is inserted and connected to the inner surface of the jacks 507. After the electric telescopic rods 607 are started and extended, they can be inserted into the jacks 507, so that the moving frame 501 and the moving plate 606 are quickly in a spliced state. The splicing operation of the moving frame 501 and the moving plate 606 is more convenient and fast.

[0021] As Figures 1-4 shown, brackets 7 are symmetrically and fixedly connected to the top of the bottom plate 1. A hydraulic rod 8 is fixedly connected to the outer surface of the brackets 7. The output end of the hydraulic rod 8 penetrates through the brackets 7 and extends to the other side. A clamping plate 9 is fixedly connected to the output end of the hydraulic rod 8. The profile body 4 is located between the two clamping plates 9. When sandblasting the profile body 4, the profile body 4 is placed above the bottom plate 1, and the two hydraulic rods 8 on both sides are started synchronously. The hydraulic rods 8 are started to drive the clamping plates 9 to move, and the profile body 4 can be clamped and fixed.

[0022] Usage method and working principle of this device: When sandblasting the profile body 4, place the profile body 4 above the bottom plate 1, and simultaneously start the hydraulic rods 8 on both sides. When the hydraulic rods 8 are started, they drive the clamping plates 9 to move, and then the profile body 4 can be clamped and fixed. After clamping, put the moving frame 501 on the outer side of the profile body 4. At this time, the middle profile body 4 is supported by the rollers 505 on both sides. At the same time, start the electric telescopic rod 607 to extend. After the electric telescopic rod 607 is started and extended, it can be inserted into the jack 507, so that the moving frame 501 and the moving plate 606 are quickly in a splicing state. Subsequently, use the sandblasting nozzle 608 to pass through the avoidance groove 502 to perform sandblasting on the bottom profile body 4. While sandblasting, start the motor 602 to drive the lead screw 603 to rotate. Through the rotation of the lead screw 603, the sliding block 604 can be driven to move along the limiting rod 605. The sliding block 604 drives the moving plate 606 and the sandblasting nozzle 608 to move accordingly, completing the covering sandblasting of the profile body 4. While the moving plate 606 moves to adjust the sandblasting position, since the moving plate 606 is in a splicing state with the bottom moving frame 501, the moving plate 606 will drive the moving frame 501 to move accordingly. That is, while moving the sandblasting position, the moving frame 501 is always outside the sandblasting position of the profile body 4. By using the moving frame 501, the shape of the profile body 4 is calibrated, so that the sandblasting position of the profile body 4 always maintains a stable shape, avoiding the deformation of the profile body 4 due to sag during overall clamping, which affects the accuracy of the sandblasting position.
