Description

Special fixture of whole case in carriage powder spray pin structure sideboard

Technical Field

The utility model relates to a carriage application technical field, concretely relates to whole case in carriage cant chisei structure sideboard special fixture.

Background

The conventional paint spraying process adopted by a truck compartment has the problems of high VOC (volatile organic compounds) emission, difficult solid waste treatment, high coating cost and the like. The whole carriage powder spraying process is a successful application of the electrostatic powder spraying process in truck coating, solves the problem of environmental protection, improves the automation level, reduces the coating cost and improves the coating quality.

Powder is also required to be sprayed on the superposed surface between the carriage side plate H and the upright post M so as to avoid corrosion failure.

The side plates of the label box and the bin gate can not be fixedly arranged with cables before the spraying process, but each side plate needs to be opened at a certain angle to complete powder spraying, and after the powder spraying is finished, the side plates can not be completely closed and must be controlled at a certain angle to prevent overlapped flour from being scraped and rubbed to expose bottoms. In actual production, iron wires or ropes are mostly adopted for fixation, but the problems of long disassembly and assembly time, large workload and low efficiency exist.

Disclosure of Invention

In order to solve the problem that the powder spraying efficiency is low because a certain angle needs to be opened for the side plate of the existing carriage lapping rod structure, the utility model provides a special fixture for the side plate of the whole carriage powder spraying bolt rod structure.

The invention conception is as follows: in view of the fact that the side plate H of the existing carriage butt strap structure is provided with a bolt hook L with a limiting groove, the side edge of which extends out, and the stand column M is provided with a bolt rod hole N corresponding to the opening of the limiting groove on the bolt hook. According to the position relation of the bolt rod hole and the bolt hook, the clamp is designed in consideration, one side of the clamp is clamped with the bolt rod hole, the bolt hook is hung at the other side of the clamp, a gap with a certain angle is reserved, the clamp is convenient to disassemble and assemble, and the technical requirement of powder spraying of the whole carriage is met.

Therefore, the technical scheme of the utility model is that: the utility model provides a special fixture of whole case of carriage powder spray pin structure sideboard which characterized in that: comprises a cross bar, hanging parts are symmetrically arranged at two ends of the cross bar,

the hanging part is a limiting pin which is vertical to the cross rod and extends upwards and downwards, the length of the vertical extension is asymmetric, the sum of the length of the short side and the diameter of the cross rod is smaller than the diameter of the bolt hole, and the length of the limiting pin is larger than the diameter of the bolt hole;

the bottom of the cross rod extends downwards to be connected with a U-shaped rod, the open end of the U-shaped rod is fixed at the bottom of the cross rod to form a closed middle cavity, and the middle cavity is used for being sleeved with a bolt hook and limiting and fixing the bolt hook;

the distance between the limiting pin and the U-shaped rod on the two sides is unequal, the limiting pin and the U-shaped rod can be matched with the U-shaped rod to form two clamps with different opening and closing angles, and when the limiting pin on one side is used, the other side can be used as a handheld part.

The technical scheme is further improved as follows: the fixture is made of round steel rim charge with the diameter of 6-8 mm. The manufacturing cost is low by utilizing waste materials; meanwhile, the round steel with the thickness of 6-8mm is adopted, so that the shielding surface is small while the strength is ensured, and the workload of subsequent paint repair is reduced.

The technical scheme is further improved in that: the fixture is made of round steel rim charge with the diameter of 6 mm. The shielding surface is reduced to the maximum extent while the strength is ensured, and the workload of subsequent paint repair is reduced.

Has the advantages that: compared with the prior art, the utility model has the characteristics of simple structure, loading and unloading are convenient, facilitate the use, repeatedly usable, alleviate work load by a wide margin, shorten process time, promote the beat, improve the operating efficiency. Meanwhile, the clamp forms two opening and closing angles by matching any limiting pin on two sides with the U-shaped rod, so that the clamp can be flexibly selected according to needs, and the problems of opening, closing and fixing of the overlapped surface of the side plate powder spraying front side plate and the upright post are solved.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings, but the embodiment should not be construed as limiting the present invention.

The utility model discloses as shown in fig. 1 to 5:

a special clamp P for a side plate of a powder spraying bolt rod structure of a carriage comprises a cross rod 1, hanging parts are symmetrically arranged at two ends of the cross rod,

the hanging part is a limiting pin 2 which is vertical to the cross rod and extends upwards and downwards, the length of the limiting pin positioned below the cross rod is greater than that of the limiting pin positioned above the cross rod, the length from the bottom of the cross rod to the upper end of the limiting pin is less than the diameter of the bolt rod hole N, and the length of the limiting pin is slightly greater than that of the bolt rod hole (ensuring that the bolt rod hole can be conveniently put into and taken out at a certain angle and meanwhile, the natural falling is avoided);

the bottom of the cross rod extends downwards to be connected with a U-shaped rod 3, the open end of the U-shaped rod is fixed at the bottom of the cross rod to form a closed middle cavity 4, and the middle cavity is used for sleeving a bolt hook and limiting and fixing the bolt hook;

the distance inequality of the limiting pin and the U-shaped rod on the two sides can be matched with the U-shaped rod to form two clamps with different opening and closing angles, and when the limiting pin on one side is used, the other side can be used as a handheld part and is convenient to operate.

The fixture is made of round steel rim charge with the diameter of 6 mm. The manufacturing cost is low by utilizing waste materials; meanwhile, 6mm round steel is adopted, so that the shielding surface is small while the strength is ensured, and the workload of subsequent paint repair is reduced.

The utility model discloses a use method:

open the sideboard earlier (avoid interfering), with fixture wherein one end spacer pin adjustment certain angle cartridge in the bolt hole on stand M, rotatory fixture to U type pole orientation keep away from sideboard one side (and upwards lift up the other end spacer pin, form when avoiding the sideboard to close and interfere), close the sideboard, place the U type pole in directly over the hitch, clockwise rotation horizontal pole, the hitch outer end passes from the middle cavity of U type pole, when the U type pole changes to vertical direction, just in time be located the spacing groove of hitch, at this moment open certain angle and U type pole looks butt with the sideboard, the one end of fixture articulates in the bolt hole this moment, thereby realize that the sideboard opens certain angle and articulates on fixture.

When the powder spraying process is completed and the clamp needs to be taken down, the side plates are closed, the clamp rotates anticlockwise (rotates around the bolt rod hole), the U-shaped rod is wound out of the bolt hook, the side plates are opened, and the clamp is adjusted to a certain angle and taken out.

Those skilled in the art will appreciate that the detailed description is not provided herein in detail.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
