Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a sand blasting clamp, which can solve the problem that sand blasting media can enter a gap in the sand blasting process of a clamp made of an integral steel material to influence the appearance of an outer conical surface of a product. Meanwhile, the problem that the existing integral polyurethane clamp is deformed after being used for a period of time, the gap between the positioning surface of the clamp and the outer conical surface of the product is enlarged, and the sand blasting medium enters the gap to cause poor appearance of the outer conical surface of the product after being locally blasted is solved.

As shown in fig. 1 and 2, the sandblasting jig comprises a jig base 3 and an elastic insert 4, wherein a groove is formed at the top end of the jig base 3, and the elastic insert 4 is embedded in the groove at the top end of the jig base 3. The elastic insert 4 is of an annular structure, the inner side surface of the elastic insert 4 and the bottom surface of the groove of the clamp base 3 are surrounded to form a containing cavity, and the containing cavity is used for containing a product 6 to be subjected to sand blasting.

After the product 6 to be subjected to sand blasting is clamped in the accommodating cavity, the outer surface of the product 6 to be subjected to sand blasting is abutted against the inner side surface of the elastic insert 4 without a gap, and then the product 6 to be subjected to sand blasting can be subjected to sand blasting. In order to further avoid influencing the outer surface of the product during sandblasting, when the product 6 to be sandblasted is placed in the accommodating cavity, the upper end surface of the product 6 to be sandblasted is slightly lower than the upper end surface of the elastic insert 4, that is, the elastic insert 4 is higher than the product 6 to be sandblasted, so that the outer surface of the product 6 to be sandblasted and the inner side surface of the elastic insert 4 are completely attached to the whole outer conical surface of the product 6 to be sandblasted and are completely wrapped by the elastic insert 4, and the outer conical surface of the product 6 to be sandblasted is prevented from being partially exposed out of the elastic insert 4, so that the outer conical surface of the product 6 to be sandblasted is prevented from being sandblasted, and the appearance quality problem of the product 6 to be sandblasted is finally caused.

Further, in order to avoid a large amount of blasting accumulated on the bottom surface of the groove at the top end of the jig base 3, the bottom of the groove is provided with a through hole communicating with the groove so that excess blasting can be discharged through the through hole. On the other hand, in order to be able to place the product 6 to be sandblasted, the diameter of the through hole is therefore smaller than the size of the bottom surface of the groove. The bottom surface of the groove and the inner side surface of the elastic insert 4 are surrounded to form a containing chamber for containing a product 6 to be sandblasted.

The elastic insert 4 can deform and wear after being used for a certain time, at the moment, the elastic insert 4 which is already scrapped can be removed, a new elastic insert 4 is embedded again, and the clamp base 3 can be reused.

This application adopts the sandblast anchor clamps of combination formula, designs integral anchor clamps for the components of a whole that can function independently, avoids using the anchor clamps sandblast in-process sandblast medium of integral steel material to enter into clearance department, influences the outward appearance of the outer conical surface of product. Meanwhile, the problem that the appearance of the product outer conical surface is poor after local sandblasting due to the fact that the gap between the positioning surface of the clamp and the product outer conical surface is enlarged and the sandblasting medium enters the gap is solved.

In addition, when the service life of the elastic insert 4 is over, the new elastic insert 4 can be repeatedly embedded, and compared with an integral steel material positioning body or an integral polyurethane material positioning body, the service life of the tool is greatly prolonged, and the manufacturing cost of the tool is reduced.

Preferably, in another embodiment of the present application, the inner side surface of the elastic insert 4 is a tapered surface, and the inner side surface of the elastic insert 4 extends along the direction from the top end of the fixture base 3 to the bottom of the groove and gradually approaches the central axis of the through hole, so as to facilitate the insertion and the removal of the product 6 to be sandblasted.

Preferably, in the other embodiment of the present application, the blasting jig further includes a mounting plate 1, and a plurality of support rods 2 connected between the jig base 3 and the mounting plate 1, the support rods 2 being detachably connected to the jig base 3 and the mounting plate 1, so that different sizes of job titles can be selected according to different assembly environments, thereby adjusting the height of the jig base 3.

Preferably, in another embodiment of the present application, the end surface of each support rod 2 is provided with a connection boss, the bottom end of the clamp base 3 is provided with a plurality of mounting grooves, and the plurality of connection bosses are embedded into the plurality of mounting grooves in a one-to-one correspondence.

Preferably, in the other embodiments of the present application, the plurality of support rods 2 are uniformly arranged on the periphery of the mounting plate 1 in a ring shape, so as to realize stable support for the clamp base 3, the elastic insert 4 and the product 6 to be sandblasted.

Preferably, in this application in other embodiments, the mounting panel 1 is provided with a mounting hole, and the mounting hole is used for being connected with the drive of external drive motor, and drive motor drive mounting panel 1 rotates, and mounting panel 1 passes through bracing piece 2 and drives anchor clamps base 3 and elasticity insert 4 rotatory, carries out the sandblast when waiting to sandblast product 6 to keep rotating promptly for the effect of sandblast is better even. Therefore, in order to prevent the support rod 2 from being removed, the support rod 2 and the mounting plate 1 may be fixedly connected by screws or bolts.

Preferably, in another embodiment of the present application, the elastic insert 4 is a polyurethane insert, which is made of a polyurethane material, and the thickness of the polyurethane material can be set according to different requirements, for example, the thickness of one side is about 5mm, and the exterior of the polyurethane material is supported by the fixture base 3, so that the polyurethane material is not easily deformed after long-term use. The polyurethane insert can deform and wear after being used for a certain time, at the moment, the scrapped polyurethane insert can be removed, a new polyurethane insert is inlaid again, and the clamp base 3 is reused. The outer conical surface of the product 6 to be sand-blasted is positioned with the inner side surface of the polyurethane insert, a certain interference is designed between the outer conical surface of the product 6 to be sand-blasted and the inner hole of the polyurethane insert, and the problem of appearance quality of the outer conical surface of the product caused by the entering of a medium in the sand blasting process is prevented.

Preferably, in another embodiment of the present application, the clamp base 3 is adhesively connected to the elastic insert 4, for example, the clamp base 3 and the elastic insert 4 are fixed by 502 glue.
