Drawings
Fig. 1 is a schematic structural view of a protective fixture for a spraying process of the present invention.
Description of reference numerals: the wheel rim protection device comprises a base 1, a fixing rod 2, a connecting rod 3, a spring 4, a protection block 5, a fixing block 6, a protection pipe 7 and a wheel rim workpiece 8.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to the drawings, a protective clamp for a spray coating process comprises: base 1, dead lever 2, connecting rod 3, spring 4, protection piece 5 and fixed block 6. The fixed rod 2 is arranged in the base 1, and the connecting rod 3 is inserted in the fixed rod 2. Spring 4 is located dead lever 2, and the one end of spring 4 is connected on dead lever 2, and the other end of spring 4 is connected on connecting rod 3, and connecting rod 3 passes through spring 4 with dead lever 2 and is connected. The fixing block 6 and the base 1 can be formed integrally or connected through threads.
One end of the base 1, which is in contact with the protection block 5, is stepped, and the diameter of the step below the base 1 is larger than that of the step above the base 1. The stepped arrangement enables the protective block 5 to be better connected to the base 1.
The protective block 5 is annular, the protective block 5 is sleeved on the base 1, and the protective block 5 is in contact with the rim workpiece 8. The flatness of the contact surface of the protective block 5 and the rim workpiece 8 is less than or equal to 0.1mm, so that the protective block 5 and the rim workpiece 8 can be better and tightly attached. The material of protection piece 5 sets up to aluminium, and the smooth melting point in surface is high, is difficult to the oxidation when using, can improve its life.
In order to increase the contact area between the protection block 5 and the rim workpiece 8, the protection block 5 comprises a supporting portion and a fastening portion, the fastening portion is arranged below the supporting portion, the fastening portion is sleeved on the base 1, the inner diameter of the supporting portion is smaller than that of the fastening portion, and the supporting portion is in contact with the rim workpiece 8. That is, the vertical section of the protection block 5 is an inverted L-shaped, and the part of the rim workpiece 8 which does not need to be sprayed can be effectively shielded through the supporting part, so that the protection effect can be better achieved.
The fixed block 6 is arranged at the free end of the connecting rod 3, and the fixed block 6 is positioned on the base 1. The fixed block 6 is set to be frustum-shaped, and the diameter of the fixed block 6 close to one end of the base 1 is larger than the diameter of the fixed block 6 far away from one end of the base 1. That is, the outer surface of the fixing block 6 is an inclined surface, which is convenient for the rim workpiece 8 to be sleeved on the fixing block 6 and also ensures that the rim workpiece 8 can be well fixed on the fixing block 6. The rim work piece 8 is in the same direction as smooth to base 1 under the effect of self gravity, because fixed block 6 diameter is big more down, rim work piece 8 and fixed block 6 interference fit this moment, rim work piece 8 card is on fixed block 6, realizes rim work piece 8 automatic positioning, and whole location process required time is only 2s ~ 3s, laborsaving during the festival.
The protection clamp further comprises a protection tube 7, and the protection tube 7 is sleeved at the lower end of the base 1. The protection tube 7 can be made of plastic materials, and the protection tube 7 can be fixedly connected with the base 1 through bolts. The setting through protection tube 7 can play certain guard action to base 1, can play the supporting role to base 1 again, is convenient for the connection of 1 other equipment of base.
In the actual use process, the rim workpiece 8 is sleeved from the fixing block 6, the fixing block 6 slides downwards under the action of self gravity, and the spring 4 is pressed by pressure to drive the connecting rod 3 and the fixing block 6 to descend until the rim workpiece 8 is contacted with the fixing block 6. Because the fixed block 6 is frustum-shaped, the rim workpiece 8 slides to the upper end of the base 1, automatic positioning is realized, and the required time is short. Meanwhile, the part of the rim workpiece 8 which does not need to be sprayed is in contact with the upper end face of the protective block 5, so that the protective effect is achieved. After the rim workpiece 8 is installed, the rim workpiece 8 sequentially and stably enters the spraying room, the rim workpiece 8 is assembled with the protection clamp tightly, and the rim cannot incline or even fall to the ground due to the large pressure of the nozzle. After painting is finished, the rim workpiece 8 can be gently taken down, and meanwhile, the clamp is cleaned to keep clean. And finally, the protection block 5 is taken down and placed at a standby position, and the protection block 5 can be recycled.
The above is only the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
