Description

Technical Field

[0001] The invention relates to the technical field of parts assembly, in particular to an assembly tool. Background Art

[0002] High-precision disc parts of engines mainly support the turbine shaft, which drives the blades to work. Disc parts require high precision of inner hole and outer circle. Such parts are widely used in aerospace and aviation engine fields.

[0003] Figure 1 It is an axial orthographic projection view of a rotating part; Figure 2 for Figure 1 Schematic diagram of the local section along the AA direction. Figure 1 , Figure 2 As shown in the figure, a plurality of assembly holes are arranged on the side wall of the inner hole of the part, and the assembly holes are arranged obliquely and at a 45° angle to the axis of the part. During assembly, a pin needs to be inserted into the assembly hole. Since the pin and the assembly hole are interference fit, the inner ring of the mold needs to be attached to the side wall of the part by the inner ring conical surface, and a guide hole is added at the assembly location to guide the pin for assembly.

[0004] However, the workpiece and the inner ring are prone to movement during the assembly process, and it is difficult for the pins and tools to be subjected to vertical force, which results in a low qualified rate of assembled parts and difficulty in rework. The parts require high skill levels of operators, and assembly problems are prone to cause parts to be scrapped, resulting in high manufacturing costs and difficulty in meeting customer delivery cycles. Therefore, there is an urgent need for an assembly tool that can improve the stability during assembly and make it easier for the pins to be subjected to vertical force during assembly, thereby improving assembly accuracy, reducing assembly difficulty, speeding up assembly speed, and reducing the chance of parts being scrapped. Summary of the invention

[0005] In view of the above problems in the prior art, the present application provides an assembly tool that can improve the stability during assembly and make it more convenient for the pins to be subjected to vertical force during assembly, thereby improving the assembly accuracy, reducing the difficulty of assembly, speeding up the assembly speed, and reducing the chance of parts being scrapped.

[0006] The present application provides an assembly tool, which is used to install a pin in an assembly hole of a part, wherein the assembly hole is arranged at an angle, and the pin is interference fit with the assembly hole; the tool comprises: a support mechanism, wherein the support mechanism has a support surface, wherein the support surface is used to place the part, wherein the support surface is arranged at an angle, and wherein the inclination angle of the support surface is set such that after the part is placed on the support surface, the opening of the assembly hole is arranged vertically upward; and a clamping mechanism, wherein the clamping mechanism is used to clamp and fix the part on the support surface.

[0007] By adopting the above structure, the opening of the assembly hole of the part placed on the support surface can be made to face vertically upward by means of the inclined support surface, so that when the pin with interference fit is inserted into the assembly hole, the pin can be subjected to force vertically downward. As a result, the probability of movement during assembly can be reduced, thereby improving assembly accuracy, reducing assembly difficulty, speeding up assembly speed, and reducing the probability of parts being scrapped. In addition, the part can be clamped and fixed on the support surface by means of a clamping mechanism, so that when the pin is inserted into the assembly hole, the part can be made more stable, thereby further reducing the probability of movement during assembly, thereby improving assembly accuracy, reducing assembly difficulty, speeding up assembly speed, and reducing the probability of parts being scrapped.

[0008] In some embodiments, the support mechanism further has a positioning member, which is disposed on the support surface. After the part is placed on the support surface, the positioning member abuts against the part to prevent the part from sliding downward along the support surface.

[0009] With the above structure, by arranging a positioning piece on the support surface to abut against the part, the part is prevented from sliding downward along the support surface, so that when the pin is installed in the assembly hole and the pin is subjected to vertical downward force, the part is prevented from sliding downward along the support surface. In this way, the stability of the part during assembly can be improved, thereby improving the assembly accuracy and reducing the probability of part scrapping.

[0011] By adopting the above structure, the positioning member is adapted to the shape of the part, so that the contact between the part and the positioning member can be made more stable, thereby improving the assembly accuracy and reducing the probability of part scrapping.

[0012] In some embodiments, the part is a disc-like part; and the positioning part is in an arc shape.

[0013] By adopting the above structure, the positioning member is set to an arc shape, so that the contact area between the positioning member and the disk-like parts can be increased, so that the abutment between the parts and the positioning member can be more stable, thereby improving the assembly accuracy and reducing the probability of parts being scrapped.

[0014] In some embodiments, the inclination angle of the support surface is 30°, 45° or 60°.

[0015] With the above structure, the supporting surface has an inclination angle of 30°, 45° or 60°, so that the assembly tool can be adapted to the assembly hole with an inclination angle of 30°, 45° or 60°.

[0016] In some embodiments, the clamping mechanism is provided in plurality.

[0017] By adopting the above structure, the parts on the support surface can be clamped and fixed by multiple clamping mechanisms, thereby improving the stability and firmness of the parts, and further improving the assembly accuracy of the parts and reducing the probability of scrapping the parts.

[0018] In some embodiments, the support surface is a square plane, the positioning member is located at a corresponding position in the middle of the lower edge of the support surface, and two clamping mechanisms are provided, which are respectively located at corresponding positions at both ends of the upper edge of the support surface.

[0019] By adopting the above structure, the two clamping mechanisms and the positioning parts can form a triangular layout, so that the parts clamped and fixed on the supporting surface can be more stable and firm, thereby improving the assembly accuracy of the parts and reducing the probability of parts being scrapped.

[0020] In some embodiments, the clamping mechanism includes: a pressing member, which is located above the supporting surface, spaced apart from the supporting surface, and can be close to or away from the supporting surface.

[0021] With the above structure, the parts on the supporting surface can be pressed or loosened by driving the pressing member to approach or move away from the supporting surface.

[0022] In some embodiments, the clamping mechanism further includes: a mounting seat, the mounting seat is fixedly mounted on the supporting surface, and the clamping member is disposed on the mounting seat and is threadedly connected to the mounting seat.

[0023] With the above structure, the distance between the pressing member and the supporting surface can be adjusted by rotating the pressing member, so that the parts on the supporting surface can be conveniently clamped and fixed.

[0024] In some embodiments, the pressing member is disposed perpendicularly to the supporting surface.

[0025] By adopting the above structure, the clamping member is arranged perpendicular to the supporting surface, so that when the clamping member presses and fixes the part on the supporting surface, the force applied by the clamping member to the part is perpendicular to the supporting surface, thereby improving the stability and firmness of the part, thereby improving the assembly accuracy of the part and reducing the chance of part scrapping.

[0032] Below, in conjunction with the accompanying drawings, a possible embodiment of the assembly tool 10 in the present application is exemplarily described.

[0033] like Figure 3-Figure 6 As shown, the present application provides an assembly tool 10, which is used to install a pin in an assembly hole 21 of a part 20, the assembly hole 21 is arranged obliquely, and the pin and the assembly hole 21 are interference fit. The assembly tool 10 includes a support mechanism 100 and a clamping mechanism 200, wherein the support mechanism 100 has a support surface 110, the support surface 110 is used to place the part 20, the support surface 110 is arranged obliquely, and the angle of inclination of the support surface 110 is set such that after the part 20 is placed on the support surface 110, the opening of the assembly hole 21 is arranged vertically upward, and the clamping mechanism 200 is used to clamp and fix the part 20 on the support surface 110. Thus, the opening of the assembly hole 21 of the part 20 placed on the support surface 110 can be made to face vertically upward through the obliquely arranged support surface 110, so that when the interference fit pin is installed in the assembly hole 21, the pin can be forced vertically downward. Thus, the probability of movement during assembly can be reduced, thereby improving assembly accuracy, reducing assembly difficulty, accelerating assembly speed, and reducing the probability of scrapping of the part 20. In addition, the part 20 can be clamped and fixed on the support surface 110 by the clamping mechanism 200, so that the part 20 can be more stable when the pin is installed in the assembly hole 21, which can further reduce the probability of movement during assembly, thereby improving the assembly accuracy, reducing the difficulty of assembly, speeding up the assembly speed, and reducing the probability of scrapping the part 20.

[0034] like Figure 3-Figure 6 As shown, in some embodiments, the support mechanism 100 further has a positioning member 130, which is arranged on the support surface 110. After the part 20 is placed on the support surface 110, the positioning member 130 abuts against the part 20 to prevent the part 20 from sliding downward along the support surface 110. Thus, by arranging the positioning member 130 on the support surface 110 to abut against the part 20, the part 20 is prevented from sliding downward along the support surface 110, so that when the pin is installed in the assembly hole 21 and the pin is subjected to vertical downward force, the part 20 is prevented from sliding downward along the support surface 110. Thus, the stability of the part 20 during assembly can be improved, thereby improving the assembly accuracy and reducing the probability of the part 20 being scrapped.

[0035] like Figure 3 , Figure 5 As shown, in some embodiments, the positioning member 130 is adapted to the shape of the part 20. Thus, by making the positioning member 130 and the shape of the part 20 adapted, the abutment between the part 20 and the positioning member 130 can be made more stable, thereby improving the assembly accuracy and reducing the probability of the part 20 being scrapped.

[0036] like Figure 3 , Figure 5 As shown, in some embodiments, the part 20 is a disc-like part 20; the positioning member 130 is in an arc shape. Therefore, by setting the positioning member 130 in an arc shape, the contact area between the positioning member 130 and the disc-like part 20 can be increased, so that the contact between the part 20 and the positioning member 130 can be more stable, thereby improving the assembly accuracy and reducing the probability of the part 20 being scrapped.

[0037] like Figure 3 , Figure 5 As shown, in some embodiments, the diameter of the positioning member 130 is the same as the diameter of the part 20. Thus, the positioning member 130 can fit the outer circumference of the part 20, thereby increasing the contact area between the positioning member 130 and the disc-like part 20, so that the contact between the part 20 and the positioning member 130 is more stable, thereby improving the assembly accuracy and reducing the probability of the part 20 being scrapped.

[0038] like Figure 3 , Figure 5 As shown, in some embodiments, the arc of the positioning member 130 is about 120°. Thus, the contact area between the positioning member 130 and the disc-like part 20 can be increased, so that the contact between the part 20 and the positioning member 130 is more stable, thereby improving the assembly accuracy and reducing the probability of the part 20 being scrapped.

[0039] In some embodiments, the inclination angle of the support surface 110 is 30°, 45° or 60°. Thus, the assembly tool 10 can be adapted to the assembly hole 21 with an inclination angle of 30°, 45° or 60° by the inclination angle of the support surface 110 being 30°, 45° or 60°.

[0040] In some embodiments, the inclination angle of the support surface 110 is adjustable. Specifically, the support mechanism 100 further includes a base 120, one side edge of the support surface 110 is hinged to the base 120, and a support column is provided on the base 120, and the support column is used to support the support surface 110. The length of the support column is adjustable, and by adjusting the length of the support column, the inclination angle of the support surface 110 can be adjusted. In this way, the support surface 110 can be adapted to the assembly holes 21 of different inclination angles, thereby improving the adaptation range of the assembly tool 10.

[0041] In some embodiments, a plurality of assembly holes 21 are provided on the part 20, and the plurality of assembly holes 21 are arranged in a circle around the axis of the part 20, and the angles between each assembly hole 21 and the axis of the part 20 are the same. The support mechanism 100 further includes a rotating structure, and the support surface 110 is provided on the rotating structure, so that the support surface 110 can rotate, and the axis of rotation is perpendicular to the support surface 110. Thus, after the pin in one assembly hole 21 is assembled, the opening of another assembly hole 21 on the part 20 can be made vertically upward by rotating the support surface 110, so as to assemble the other assembly hole 21. Thus, the number of times of disassembling and assembling the part 20 can be reduced, the operation steps and assembly time can be reduced, and the production efficiency can be improved.

[0042] In some embodiments, the support mechanism 100 further includes a fixing structure. After the support surface 110 rotates to a predetermined position, the support surface 110 can be fixed by the fixing structure so that the opening of the predetermined assembly hole 21 is vertically upward and can maintain a fixed position to prevent the support surface 110 from rotating when the pin is assembled. Specifically, the fixing structure can be, for example, a snap connection structure formed by a snap joint and a snap opening to snap the support surface 110 to prevent the rotating structure from rotating. The fixing structure can also be, for example, a fastening connection structure formed by a rotating bolt abutting against the support surface 110 to fix the support surface 110 to prevent the rotating structure from rotating.

[0043] like Figure 3 , Figure 5 As shown, in some embodiments, a plurality of clamping mechanisms 200 are provided. Specifically, the clamping mechanism 200 has a quick clamping structure, which can quickly clamp and fix the part 20 on the support surface 110. Thus, the part 20 on the support surface 110 can be clamped and fixed by a plurality of clamping mechanisms 200, thereby improving the stability and firmness of the part 20, thereby improving the assembly accuracy of the part 20, and reducing the probability of the part 20 being scrapped.

[0044] like Figure 3 , Figure 5 As shown, in some embodiments, the support surface 110 is a square plane, the positioning member 130 is located at a corresponding position in the middle of the lower edge of the support surface 110, and two clamping mechanisms 200 are provided, which are respectively located at corresponding positions at both ends of the upper edge of the support surface 110. Thus, the two clamping mechanisms 200 and the positioning member 130 can form a triangular layout, so that the part 20 clamped and fixed on the support surface 110 can be more stable and firm, thereby improving the assembly accuracy of the part 20 and reducing the probability of the part 20 being scrapped.

[0045] like Figure 3-Figure 6As shown, in some embodiments, the clamping mechanism 200 includes a pressing member 210, which is located above the support surface 110, spaced apart from the support surface 110, and can approach or move away from the support surface 110. Thus, the part 20 on the support surface 110 can be pressed or loosened by driving the pressing member 210 to approach or move away from the support surface 110.

[0046] like Figure 3-Figure 6 As shown, in some embodiments, the clamping mechanism 200 further includes a mounting seat 220, which is fixedly mounted on the support surface 110, and a pressing member 210 is disposed on the mounting seat 220 and is threadedly connected to the mounting seat 220. Thus, the distance between the pressing member 210 and the support surface 110 can be adjusted by rotating the pressing member 210, so that the part 20 on the support surface 110 can be conveniently clamped and fixed.

[0047] like Figure 4 , Figure 6 As shown, in some embodiments, the pressing member 210 is disposed perpendicularly to the support surface 110. Thus, by disposing the pressing member 210 perpendicularly to the support surface 110, when the pressing member 210 presses and fixes the part 20 on the support surface 110, the force applied by the clamping member to the part 20 is perpendicular to the support surface 110, thereby improving the stability and firmness of the part 20, thereby improving the assembly accuracy of the part 20 and reducing the probability of the part 20 being scrapped.

[0048] In some embodiments, the mounting seat 220 is slidably connected to the support surface 110 along the radial direction of the part 20 on the support surface 110. Therefore, the position of the mounting seat 220 can be adjusted according to the diameter of the part 20, so that the assembly tool 10 can be adapted to parts 20 of different diameters, thereby improving the adaptation range of the assembly tool 10. The above content is an exemplary description of possible embodiments of the assembly tool 10 in the present application. Below, in conjunction with the accompanying drawings, the specific structure of the assembly tool 10 in the present application is described in detail in a specific embodiment.

[0049] Figure 3 This is a schematic diagram of the front side orthographic projection structure of the assembly tool 10 after fixing the part 20 in this application; Figure 4 This is a schematic diagram of the left side orthographic projection structure of the assembly tool 10 after fixing the part 20 in this application; Figure 5 It is a schematic diagram of the front side orthographic projection structure of the assembly tool 10 in this application; Figure 6 Schematic diagram of the left side projection structure of the assembly tool 10 in this application. Figure 3-Figure 6As shown, the assembly tool 10 in the present application includes a support mechanism 100 and a clamping mechanism 200. The support mechanism 100 is used to support the part 20 so that the opening of the assembly hole 21 on the part 20 is vertically facing upward, so that the pin with interference fit can be inserted into the assembly hole 21, and the probability of movement during assembly can be reduced, thereby improving the assembly accuracy, reducing the assembly difficulty, speeding up the assembly speed, and reducing the probability of the part 20 being scrapped. The clamping mechanism 200 is used to clamp and fix the part 20 on the support mechanism 100, so as to improve the firmness and stability of the part 20 during assembly, thereby improving the assembly accuracy and assembly efficiency.

[0050] like Figure 3-Figure 6 As shown, the support mechanism 100 includes a support surface 110 and a base 120. The support surface 110 is a square plane. The base 120 is a triangular prism frame structure as a whole. When viewed from the side, the base 120 is an equilateral right triangle. That is, the surface corresponding to a right-angled side of the base 120 is used for horizontal placement, and the surface corresponding to the hypotenuse of the base 120 is used to install the support surface 110. The support surface 110 is fixedly mounted on the surface corresponding to the hypotenuse of the base 120 by a plurality of hexagon socket screws, so that the support surface 110 is tilted at an angle of 45°.

[0051] like Figure 3-Figure 6 As shown, the support mechanism 100 further includes a positioning member 130. The positioning member 130 is fixedly arranged on the support surface 110, and is located at a position corresponding to the lower edge of the support surface 110. The positioning member 130 is in an arc shape, which matches the shape of the part 20. The arc of the positioning member 130 is about 120°. After the part 20 is placed on the support surface 110, the positioning member 130 abuts against the part 20, and fits the downwardly inclined side of the part 20, preventing the part 20 from sliding downward along the support surface 110, while reducing the possibility of the part 20 shaking left and right.

[0052] like Figure 3 , Figure 5 As shown, two clamping mechanisms 200 are provided, which are respectively located at corresponding positions at both ends of the upper edge of the support surface 110. Thus, the two clamping mechanisms 200 and the positioning member 130 can form a triangular layout, so that the part 20 clamped and fixed on the support surface 110 can be more stable and firm, thereby improving the assembly accuracy of the part 20 and reducing the probability of the part 20 being scrapped.

[0053] like Figure 3-Figure 6As shown, the clamping mechanism 200 includes a clamping member 210 and a mounting seat 220. The mounting seat 220 is a C-shaped structure as a whole, and the end of the mounting seat 220 close to the supporting surface 110 is threadedly connected and fixed to the supporting surface 110 by a hexagon socket screw. The end of the mounting seat 220 away from the supporting surface 110 extends toward the axial position of the part 20 on the supporting surface 110, and is installed with a clamping member 210. The clamping member 210 is threadedly connected to the mounting seat 220, and the distance between the clamping member 210 and the supporting surface 110 can be adjusted by rotating the clamping member 210 to clamp and fix the part 20 on the supporting surface 110. The clamping member 210 is arranged perpendicular to the supporting surface 110, so that when the clamping member 210 presses and fixes the part 20 on the supporting surface 110, the force applied by the clamping member on the part 20 is perpendicular to the supporting surface 110, thereby improving the stability and firmness of the part 20, and further improving the assembly accuracy of the part 20 and reducing the probability of scrapping the part 20.

[0054] Note that the above are only preferred embodiments of the present application and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present application is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may also include more other equivalent embodiments without departing from the concept of the present invention, all of which belong to the protection scope of the present invention.
