[0037] Reference Figures 1-3As shown, the utility model provides a technical solution: a sandblasting tool for assembling a foam insulation workpiece 10, the foam insulation workpiece 10 includes a connecting plate 11 and a shell 12 arranged perpendicularly to each other, the shell 12 is respectively provided with a first through hole 121, a second through hole 122 and a third through hole 123, the first through hole 121 and the second through hole 122 are configured in plurality, the sandblasting tool 20 includes a back plate 21 and a stepped seat 22 arranged perpendicularly to each other, the stepped seat 22 is arranged corresponding to the first through hole 121 The first positioning pin 221 and the second positioning pin 222 are set on the stepped seat 22 corresponding to the second through hole 122, and the third positioning pin 223 is set on the stepped seat 22 corresponding to the third through hole 123; when the foamed insulation workpiece 10 is assembled on the sandblasting tooling 20, the connecting plate 11 is fitted with the back plate 21, and the shell 12 is covered on the stepped seat 22, and the first positioning pin 221, the second positioning pin 222 and the third positioning pin 223 are inserted into the first through hole 121, the second through hole 122 and the third through hole 123 one by one.

[0038] According to this embodiment, after the foamed insulation workpiece 10 is assembled to the sandblasting tool 20, the foamed insulation workpiece 10 and the sandblasting tool 20 are integrated. Then, the first positioning pin 221, the second positioning pin 222, and the third positioning pin 223 are plugged and matched with the first through hole 121, the second through hole 122, and the third through hole 123 in a one-to-one correspondence. During sandblasting, the deformation of key components can be intervened and the dimensions can be accurately controlled to prevent excessive deformation of the foamed insulation workpiece 10.

[0039] Reference Figures 1-3 As shown, in some embodiments, a receiving groove 211 is provided on one side of the back plate 21 close to the stepped seat 22 ; when the foamed insulation workpiece 10 is assembled onto the sandblasting tool 20 , the connecting plate 11 is embedded in the receiving groove 211 .

[0040] According to this embodiment, by limiting the horizontal and vertical directions of the foamed thermal insulation workpiece 10, the foamed thermal insulation workpiece 10 can be prevented from moving during size measurement, thereby ensuring a more accurate measurement result.

[0041] Reference Figures 4-6 As shown, in some embodiments, at least two anti-slip components 30 are included, and at least two anti-slip components 30 are arranged on the side of the back plate 21 away from the stepped seat 22. The anti-slip component 30 includes a support block 31, a push rod 32 and a suction cup 33. The support block 31 has an installation channel 311, the push rod 32 is arranged in the installation channel 311, the first end of the push rod 32 extends outside the installation channel 311, the installation channel 311 has a first accommodating cavity 3111, the suction cup 33 is arranged in the first accommodating cavity 3111, and the suction cup 33 is connected to the second end of the push rod 32.

[0042] Exemplarily, the support block 31 is detachably connected to the back plate 21, and the axial direction of the mounting channel 311 is parallel to the width direction of the back plate 21. The suction cup 33 and the second end of the push rod 32 can be transition fit or interference fit, or can be a bearing connection.

[0043] According to this embodiment, after the sandblasting tool 20 is placed on the working plane, the suction cup 33 is pressed down by the push rod 32 so that the suction cup 33 generates suction force on the working plane, thereby preventing the sandblasting tool 20 from being accidentally moved.

[0044] Reference Figures 4-6 As shown, in some embodiments, the mounting channel 311 has a limiting cavity 3112 and a second accommodating cavity 3113, and the support block 31 is provided with a plurality of slide grooves 3114 arranged at intervals around the axis of the mounting channel 311, and each slide groove 3114 is connected to the mounting channel 311 and the limiting cavity 3112, and the push rod 32 is constructed in a cross shape, and the push rod 32 is provided with a limiting rod 321 corresponding to each slide groove 3114, and the suction cup 33 is rotatably connected to the second end of the push rod 32, and the anti-slip assembly 30 includes an elastic member 34, which is sleeved on the push rod 32, and one end of the elastic member 34 abuts against the flange 322 of the push rod 32, and the other end of the elastic member 34 abuts against the wall of the second accommodating cavity 3113 opposite to the flange 322.

[0045] For example, the suction cup 33 and the second end of the push rod 32 may be connected by a bearing, etc. The elastic member 34 may be a spring or an elastic rubber ring, etc.

[0046] According to this embodiment, when the push rod 32 presses down on the suction cup 33, the limiting rod 321 moves along the chute 3114, and the flange 322 of the push rod 32 squeezes the elastic member 34, causing deformation. After the suction cup 33 is adsorbed on the working surface, the limiting rod 321 enters the limiting cavity 3112. At the same time, the push rod 32 is rotated so that the limiting rod 321 no longer corresponds to the chute 3114. The top wall of the limiting cavity 3112 limits the limiting rod 321, preventing the elastic member 34 from pushing the push rod 32 back to its original position, thereby ensuring that the suction cup 33 remains adsorbed on the working surface. Similarly, when the push rod 32 is rotated so that the limiting rod 321 corresponds to the chute 3114, the elastic member 34 pushes the flange 322 of the push rod 32, causing the suction cup 33 to quickly detach from the working surface. This not only allows the suction cup 33 to be quickly repositioned, but also makes removal of the suction cup 33 more labor-saving.

[0047] Reference Figure 4 and 6 As shown, in some embodiments, the anti-slip assembly 30 includes a knob 35 , which is disposed at the first end of the push rod 32 .

[0048] According to this embodiment, it is convenient to apply force to the push rod 32, thereby making the operation more labor-saving.

[0049] Reference Figures 7 and 8 As shown, in some embodiments, a storage component 40 is included, and the number of the storage components 40 is associated with the number of the anti-slip components 30. The storage component 40 includes a mounting plate 41 and a rotating plate 42. The mounting plate 41 is connected to the back plate 21, and the rotating plate 42 is rotatably provided on the mounting plate 41. A receiving hole 421 is provided on the rotating plate 42, and the support block 31 is embedded in the receiving hole 421.

[0050] According to this embodiment, when transferring the sandblasting tool 20, the rotating plate 42 is flipped to keep it parallel to the mounting plate 41, which not only prevents gravity from being too concentrated below the back plate 21, but also avoids excessive space occupation, thereby facilitating transportation.

[0051] Reference Figure 1 As shown, in some embodiments, at least one handle 50 is included, and the at least one handle 50 is provided on a side of the back plate 21 away from the stepped seat 22 .

[0052] According to this embodiment, the handle 50 can facilitate the operator to carry it.

[0053] Optionally, the back plate 21 and / or the stepped seat 22 are made of aluminum alloy or carbon fiber.

[0054] According to this embodiment, the aluminum alloy or carbon fiber material can reduce the weight of the back plate 21 and / or the stepped seat 22, making it easier to carry and install.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
