Description

Technical Field

[0001] The invention relates to the technical field of aviation parts processing auxiliary devices, and in particular to a multi-type parts processing fixture. Background Art

[0002] There are a large number of small parts in aviation parts with various shapes, such as cylindrical, square, T-shaped, etc. The final processing characteristics need to be determined according to their use, such as pins, screws, connecting transition blocks, guide blocks, transmission blocks, etc. During the processing, it is necessary to determine the actual situation on the end face, side face, etc. of the part to perform drilling, milling, grinding, welding and other processing. Due to the large number of small parts, small size, and various shapes, the traditional machine tool is used to clamp and process them one by one. The same process requires frequent replacement of parts, and sometimes due to limited on-site conditions, operators repeatedly contact parts of different shapes when clamping, which not only has low processing efficiency, but also has the problem of uneven processing quality in the same process. In addition, since the chuck of the machine tool is not built for a certain shape of parts alone, when processing the side of the part, especially for curved and bent parts, there are often problems of difficult and unstable clamping, which not only increases the scrap rate, but also has poor safety. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a multi-type parts processing fixture.

[0004] The present invention is achieved through the following technical solutions.

[0005] The multi-type parts processing fixture provided by the present invention includes a first clamping plate, a second clamping plate, and a bolt. The first clamping plate and the second clamping plate overlap on the projection plane, and at least one edge of the opposite sides of the first clamping plate and the second clamping plate are processed with clamping grooves corresponding to each other; the first clamping plate is provided with threaded holes distributed in rows, and the second clamping plate is provided with through holes corresponding to the threaded holes. There are multiple bolts, and the bolts are distributed in rows in the same direction along the distribution direction of the clamping grooves. The bolts are screwed into the threaded holes after passing through the through holes.

[0006] A strip gasket is also provided between the first clamping plate and the second clamping plate. The strip gasket is arranged in the same direction along the distribution direction of the clamping groove. The strip gasket and the clamping groove are arranged on both sides of the bolt.

[0007] The strip gasket is an elastic metal sheet.

[0008] The clamping grooves on the first clamping plate are arranged on one edge or two opposite edges of the surface, and the clamping grooves on the second clamping plate are distributed corresponding to the first clamping plate.

[0010] The threaded holes are symmetrically arranged at the upper and lower parts of the first clamping plate, the through holes are symmetrically arranged at the upper and lower parts of the second clamping plate, and clamping areas are provided in the middle parts of the first clamping plate and the second clamping plate.

[0011] When clamping parts, the bolts are arranged on a row of threaded holes or through holes that are closest to the parts.

[0012] The clamping grooves include circular clamping grooves, T-shaped clamping grooves, and strip-shaped clamping grooves.

[0013] The beneficial effects of the present invention are:

[0014] The present invention can realize the simultaneous clamping and processing of a plurality of parts of the same or different shapes, thereby improving the processing efficiency, ensuring the uniform processing quality of the same process, and improving the processing success rate for bent and folded parts; the first clamping plate and the second clamping plate are connected by rows of bolts, which has a positioning effect when the parts are clamped, and has high accuracy; the shape of the clamping groove is adapted to the part, so that it is not affected by the complex shape of the part, the clamping process is simple, and the stability is good when clamping.

[0015] Figure 1 It is a structural schematic diagram of the present invention.

[0016] In the figure: 1-first clamping plate; 2-second clamping plate; 3-threaded hole; 4-through hole; 5-bolt; 6-clamping groove; 7-strip gasket; 8-clamping area. DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0018] like Figure 1 Shown is a schematic diagram of the structure of the present invention:

[0019] The present invention provides a multi-type parts processing fixture, including a first clamping plate 1, a second clamping plate 2, and a bolt 5. The first clamping plate 1 and the second clamping plate 2 overlap on the projection plane, and at least one edge of the opposite sides of the first clamping plate 1 and the second clamping plate 2 are processed with clamping grooves 6 corresponding to each other; the first clamping plate 1 is provided with threaded holes 3 distributed in rows, and the second clamping plate 2 is provided with through holes 4 corresponding to the threaded holes 3. There are multiple bolts 5, and the bolts 5 are distributed in rows in the same direction along the distribution direction of the clamping grooves 6. The bolts 5 pass through the through holes 4 and are screwed to the threaded holes 3.

[0020] Principle: The first clamping plate 1 and the second clamping plate 2 can be conveniently clamped on the machine tool by processing a plurality of clamping grooves 6 on one edge. The shape, size and number of clamping grooves 6 of various shapes correspond to the parts actually processed. After placing the parts in the clamping grooves 6, the first clamping plate 1 and the second clamping plate 2 are clamped by tightening the bolts 5, so that a plurality of parts of different shapes can be clamped at the same time. In the same process, a plurality of parts can be processed one by one by clamping at one time.

[0021] In summary, the present invention can realize simultaneous clamping and processing of multiple parts of the same or different shapes, thereby improving processing efficiency, ensuring uniform processing quality in the same process, and improving the processing success rate for bent and folded parts; the first clamping plate 1 and the second clamping plate 2 are connected by rows of bolts 5, which has a positioning effect when the parts are clamped with high accuracy; the shape of the clamping groove 6 is adapted to the part, so that it is not affected by the complex shape of the part, the clamping process is simple, and the stability is good when clamping.

[0022] A strip gasket 7 is further provided between the first clamping plate 1 and the second clamping plate 2. The strip gasket 7 is arranged in the same direction as the distribution direction of the clamping groove 6. The strip gasket 7 and the clamping groove 6 are arranged on both sides of the bolt 5. After the parts are clamped, a certain gap is reserved between the first clamping plate 1 and the second clamping plate 2. The strip gasket 7 is inserted to fill the gap, so that the first clamping plate 1 and the second clamping plate 2 are kept roughly parallel, the stability of the clamping is improved, and each bolt 5 is convenient to adjust the clamping force of the closest part, so as to avoid the phenomenon of the part jumping out during the processing.

[0023] The strip gasket 7 is an elastic metal sheet. Through this arrangement, one or more strip gaskets 7 can be placed, and the gap has a certain adjustable amount due to its own deformation, which ensures that the parts are clamped while avoiding excessive rigidity that causes parts to be clamped, thereby improving the processing quality.

[0024] The clamping groove 6 on the first clamping plate 1 is arranged on one edge or two opposite edges of the surface, and the clamping groove 6 on the second clamping plate 2 is arranged corresponding to the first clamping plate 1. During one clamping, only one side of the clamping groove 6 is used to clamp the parts. When the one side is damaged or the shape of the part is changed, the other side can be replaced for clamping, which ensures the stability of the part clamping and improves the production efficiency.

[0025] The threaded holes 3 and through holes 4 are arranged in multiple rows, and the bolts 5 are arranged in one row. When the part clamping groove 6 on one side fails (is damaged, or the part corresponding to its shape no longer needs to be processed), the clamping groove 6 on this side can be directly milled clean together with the row of threaded holes 3 and through holes 4, and then a new clamping groove 6 can be milled out, without re-manufacturing the fixture, which improves efficiency, and the fixture has strong variability and good durability.

[0026] The threaded holes 3 are symmetrically arranged at the upper and lower parts of the first clamping plate 1, and the through holes 4 are symmetrically arranged at the upper and lower parts of the second clamping plate 2. A clamping area 8 is provided in the middle of the first clamping plate 1 and the second clamping plate 2. When the threaded holes 3 and through holes 4 at the upper or lower part are milled, the clamping area 8 is used to clamp to the machine tool, and the threaded holes 3 and through holes 4 at the other side are used to arrange the bolts 5, thereby ensuring the usability.

[0027] When clamping parts, the bolts 5 are arranged on a row of threaded holes 3 and through holes 4 closest to the parts. The stability is good, and the combination of this arrangement and the strip gasket 7 can avoid the phenomenon of parts being tightened at the bottom and loosened at the top when clamping.

[0028] The clamping groove 6 includes a circular clamping groove 6, a T-shaped clamping groove 6, and a strip clamping groove 6. The clamping groove 6 has various shapes, which can be processed according to the shape of the parts, or can be processed into individual general shapes, and can be used to clamp parts of various shapes at the same time, which is convenient for the complete set processing of parts, or when the number of machine tools is small, different parts of the same process can be clamped uniformly to improve the processing efficiency.
