Description

Technical Field

[0001] The invention relates to the technical field of welding positioning tooling, in particular to a detachable combined positioning welding tooling for a frame structure of fruit and vegetable waste processing equipment. Background Art

[0002] At present, the rapid development of the sanitation equipment industry has led to the continuous updating of the structure of fruit and vegetable waste treatment equipment, and at the same time, the quality requirements for equipment components have been continuously improved. Because the structure of the equipment frame components is complex and they are all welded, the relative position dimensions of the frame and the mounting parts are deviated, resulting in misalignment and misalignment of the sheet metal shell after assembly, which is difficult to correct. The prior art has always believed that the workpiece structure is complex and ordinary welding tooling is used for positioning. After welding is completed, the workpiece will be interfered by the tooling, and the two cannot be separated quickly. The current production status is that two technical workers cooperate to lay out according to the drawings, then spot weld and fix, and then weld to form. Affected by the large shape and mass of the workpiece and the large number of parts to be assembled, welding is time-consuming and labor-intensive, the work efficiency is extremely low, and the size and position errors are large. There is no reference reference when problems occur, and the difficulty of rework is increased, which is not conducive to mass production. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a detachable combined positioning welding tooling for the frame structure of a fruit and vegetable waste processing equipment, which has the advantages of simple structure, convenient operation, accurate positioning, time saving and labor saving, and greatly improves work efficiency.

[0004] The frame structure comprises a frame base, a front protection piece, a rear frame, a top connecting plate and a support piece.

[0005] The frame base comprises a front bottom beam and a rear bottom beam which are arranged in parallel front and back, and a plurality of bottom transverse supporting members are arranged between the front bottom beam and the rear bottom beam.

[0006] The front side guard comprises a plurality of first bent sections, second straight sections and third arc sections connected in sequence. The first section of bent channel steel connects the front bottom beam and the second section of straight channel steel. The second section extends vertically upward and is connected to the third section of arc. A plurality of front side lateral support members are arranged between adjacent front side guards.

[0007] The rear side frame comprises a plurality of vertical support members welded to the rear bottom beam, the vertical support members are welded to the top channel steel, and then connected to the third arc section of the front side protection member through the top connecting member.

[0008] To achieve the above-mentioned purpose, the present invention provides a detachable combined positioning welding tool, which consists of four parts: a tool base, a detachable limiting column, a detachable limiting top plate, and a fixing clamp.

[0009] The tool base is welded by two long I-beams and five short I-beams to form the tool bottom plane. Four rear fixed pillars are vertically welded on the rear side of the tool base. The tops of the four rear fixed pillars are welded to a channel steel to form the rear limit surface of the tool base. There are two limit supports on the right side of the tool base, which are the limit references for the right side of the tool bottom. The right sides of the four rear fixed pillars each have two limit blocks, which are fixed with screws.

[0010] The detachable limiting column is connected to the base with screws and positioned with taper pins.

[0011] One end of the detachable limiting top plate is connected to the detachable limiting column by screws, and the other end is connected to the fixed support column at the rear side of the tooling base by screws.

[0012] After the assembly is completed, the welding positioning tooling becomes a whole, and the positioning datums on the tooling are consistent with the drawing size datums of the frame structure. In actual use, the main sub-parts of the frame structure are positioned according to the positioning datums pre-set by the tooling, and clamped in the corresponding positions with fixing clamps. After spot welding, other adjacent parts are installed and welded.

[0013] After welding is completed, remove the removable limit top plate and the removable limit column, loosen the fixing bolts of the limit blocks on the rear side, separate the frame structure from the tooling, check each weld, complete the welds blocked by the tooling and the unwelded welds at the bottom of the frame structure, install and weld other support parts of the frame structure, and correct after all welding is completed.

[0014] Beneficial effects of the present invention: The present invention provides a detachable combined positioning welding tool for the frame structure of fruit and vegetable waste processing equipment, and its advantages include but are not limited to: the present invention provides a detachable combined positioning welding tool for the frame structure of fruit and vegetable waste processing equipment, and its advantages are: it helps to reduce working hours and improve production efficiency; the welding positioning is accurate and meets the drawing size and position accuracy; the combined structure is simple and feasible, easy to install and disassemble, easy to quickly separate the tooling and the workpiece, and has a wide range of applications; good interchangeability and convenient maintenance.
