Description

A press-fitting tool that can compensate for part tolerances Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, and in particular to a press-fitting tool that can compensate for part tolerances. Background Technology

[0002] With the rapid development of new energy electric drive, many irregularly shaped press-fit parts are designed for product assembly. However, traditional press-fit tools cannot compensate for the design and manufacturing dimensional tolerances of the parts themselves, which can cause the parts to become misaligned after press-fitting. This can lead to improper installation of the parts, damage to other components, and ultimately, defective assembly, resulting in the scrapping of both the parts and the components themselves. Summary of the Invention

[0003] The purpose of this invention is to provide a press-fitting tool that can compensate for part tolerances, so as to solve at least one of the above-mentioned technical problems existing in the prior art.

[0004] To solve the above-mentioned technical problems, the present invention provides a press-fitting tool that can compensate for part tolerances, used to insert irregularly shaped parts into the assembly components, comprising: a main body, a split press head assembly, and a floating support platform;

[0005] The split pressure head assembly includes several pressure heads arranged sequentially in the circumferential direction;

[0006] The plurality of pressure dividing heads are slidably disposed relative to each other in the axial direction, and at the same time, the pressure dividing heads are slidably disposed relative to the main body in the axial direction;

[0007] The floating support platform has a hinge structure on the side away from the irregular part, and the floating support platform can be swung relative to the main body through the hinge structure.

[0008] The floating support platform has a support surface on the side near the irregular part, and the inner end of the pressure dividing head abuts against the support surface.

[0009] In use, the outer end of the pressure dividing head abuts against the end face of the irregular part. The dimensional tolerance on the end face of the irregular part forces the pressure dividing heads to move relative to each other. The floating support platform then swings relative to the main body, thereby realizing the tolerance compensation of the irregular part by the pressure dividing heads.

[0010] In this application, several pressure heads can shift axially and within the tolerance range according to the dimensional tolerance changes on the end face of the irregular part. The floating support platform also rotates slightly accordingly until all pressure heads are completely and tightly against the end face of the irregular part, thereby compensating for the dimensional tolerance of the irregular part. This avoids the problem in the prior art where the presence of tolerances causes some areas of the pressure head to be suspended, resulting in the irregular part being pressed off-center or tilted during the pressing process.

[0011] Furthermore, several of the pressure dividing heads are evenly distributed in the circumferential direction.

[0012] In this application, the axial direction refers to the direction of pressure applied by the split pressure head assembly. Typically, the main body is cylindrical or cylindrical in shape, and the aforementioned axial direction is equivalent to the axis of the main body. The circumferential direction refers to the circumferential direction surrounding the aforementioned axial direction.

[0013] Furthermore, the floating support platform has a spherical or arc-shaped surface on the side away from the irregular part, and the floating support platform abuts against the main body through the spherical or arc-shaped surface, thereby realizing the swingability of the floating support platform.

[0014] Preferably, the main body has an arcuate groove adapted to the spherical surface on one side of the floating support platform.

[0015] Preferably, the main body has a flat surface on one side of the floating support platform, and the arc-shaped surface of the floating support platform abuts against the flat surface of the main body through line contact.

[0016] Alternatively, the spherical surface of the floating support platform abuts against the plane of the main body through point contact.

[0017] Furthermore, the hinge structure includes a steel ball disposed between the floating support platform and the main body, and the floating support platform and / or the main body are provided with an arc groove adapted to the steel ball.

[0018] Furthermore, the split pressure head assembly is cylindrical in shape and has a central hole in the middle;

[0019] The pressure distribution head is tile-shaped, and several pressure distribution heads are spliced ​​together to form a cylindrical body.

[0020] Furthermore, the lengths of the various pressure dividing heads are not the same in the axial direction.

[0021] Furthermore, the floating support platform is provided with a number of support arms, and each support arm is configured in a one-to-one correspondence with the pressure dividing head.

[0022] Preferably, in the circumferential direction, the support arm is positioned at the center of its corresponding pressure-dividing head. This achieves better force balance.

[0023] Furthermore, the number of the pressure dividing head and the support arm is 2, 3 or 4.

[0024] Preferably, the support arm is inclined toward the pressure dividing head, and the end face of the support arm that contacts the pressure dividing head is an outwardly convex arc surface.

[0025] Furthermore, the inner end faces of the support arm and the pressure dividing head are provided with mutually engaging limiting grooves and locking points to restrict the relative misalignment of the support arm and the pressure dividing head in the circumferential direction.

[0026] Furthermore, it also includes a bushing body, which includes a sleeve portion and a shaft portion arranged coaxially; the sleeve portion is disposed closer to the main body, and the shaft portion is disposed further away from the main body;

[0027] The floating support platform is movably disposed within the cavity of the sleeve portion;

[0028] The split pressure head assembly can be slidably mounted on the shaft body along the axial direction;

[0029] The connection between the sleeve and the shaft is provided with an opening that connects the inside and outside of the cavity of the sleeve; the support arm extends out from the opening and abuts against the inner end of the pressure dividing head.

[0030] Preferably, the sleeve portion is fixedly connected to the main body via a connecting flange.

[0031] Furthermore, it also includes an anvil block, which is slidably disposed axially within the cavity of the sleeve portion and between the floating support platform and the main body.

[0032] Furthermore, the main body is provided with a boss that extends into the cavity of the sleeve portion. The anvil is disposed between the boss and the floating support platform. During press fitting, the main body transmits pressure to the irregularly shaped parts through the boss, the anvil, the floating support platform (and its support arm), and the pressure dividing head.

[0033] Furthermore, it also includes an outer sleeve, which is fitted onto the outside of the shaft body and forms an annular limiting cavity between the outer sleeve and the shaft body. The pressure dividing head is slidably disposed in the annular limiting cavity along the axial direction. The annular limiting cavity is used to limit the radial displacement of the pressure dividing head in the shaft body.

[0034] Furthermore, the inner portion of the outer sleeve is fitted onto the sleeve portion, covering the opening and the support arm.

[0035] The fit between the inner circular surface of the inner side of the outer sleeve and the outer circular surface of the sleeve meets the positioning requirements, thereby achieving the radial positioning of the outer sleeve. This ensures the positioning accuracy, such as the coaxiality of the annular limiting cavity and the pressure dividing head.

[0036] Furthermore, it also includes a fastening bolt, and the outer sleeve and the shaft body are provided with through holes along the radial direction. After the fastening bolt passes through the through holes on the outer sleeve and the shaft body, it inherently connects the outer sleeve and the shaft body.

[0037] Furthermore, a portion of the pressure dividing head is provided with an elongated hole through which the fastening bolt passes. The pressure dividing head is slidable relative to the fastening bolt along the axial direction and within the range of the elongated hole.

[0038] Furthermore, the shaft body is a positioning shaft (i.e., the coaxiality and outer diameter tolerance of the shaft body meet the positioning design requirements), and the irregular part is provided with a positioning hole; during processing, the front end of the shaft body extends into the positioning hole, thereby ensuring the coaxiality of the split pressure head assembly and the irregular part.

[0039] Furthermore, it also includes a mounting base for connecting to the stamping head of the stamping equipment; the mounting base is provided with mounting holes, and the main body is detachably inserted into the mounting holes.

[0040] Preferably, after the main body is inserted into the mounting hole, it is locked and fixed by fastening screws.

[0041] By adopting the above technical solution, the present invention has the following beneficial effects:

[0042] The present invention provides a pressing tool that can compensate for part tolerances. It can automatically adjust the relative positions of each pressing head according to the dimensional tolerance of the pressed end face of the irregular part, thereby realizing automatic compensation for dimensional tolerances. As a result, during pressing, the irregular part is subjected to more uniform force in the circumferential direction, avoiding being pressed off-center or tilted, and ensuring assembly quality and accuracy.

[0057] The present invention will be further explained below with reference to specific embodiments.

[0058] As shown in Figures 1-8, this embodiment provides a press-fitting tool that can compensate for part tolerances, used to insert irregularly shaped parts 1 into the assembly components (not shown), which includes: a main body 10, a split press head assembly 20 and a floating support platform 30.

[0059] Referring to Figure 2, the split pressure head assembly 20 includes a plurality of pressure heads 21 arranged sequentially in the circumferential direction; the plurality of pressure heads 21 are slidably arranged relative to each other in the axial direction, and the pressure heads 21 are also slidably arranged relative to the main body 10 in the axial direction; as shown in Figures 4 and 7, the floating support platform 30 is provided with a hinge structure on the side away from the irregular part 1, and the floating support platform 30 is rotatable relative to the main body 10 through the hinge structure. The floating support platform 30 is provided with a support surface on the side close to the irregular part 1, and the inner end of the pressure head 21 abuts against the support surface.

[0060] In use, the outer end of the pressure dividing head 21 abuts against the end face of the irregular part 1. The dimensional tolerance on the end face of the irregular part 1 forces the relative misalignment of several pressure dividing heads 21. The floating support platform 30 then swings relative to the main body 10, thereby realizing the tolerance compensation of several pressure dividing heads 21 for the irregular part.

[0061] In this application, several pressure heads 21 can move axially and within the tolerance range according to the dimensional tolerance changes on the end face of the irregular part 1. The floating support platform 30 also rotates slightly accordingly until all pressure heads 21 are completely and tightly against the end face of the irregular part 1, thereby compensating for the dimensional tolerance of the irregular part 1. This avoids the situation in the prior art where the presence of tolerances causes some areas of the pressure head to be suspended, resulting in the irregular part 1 being pressed off-center or tilted during the pressing process.

[0062] Several pressure dividing heads 21 are evenly distributed in the circumferential direction. Alternatively, the several pressure dividing heads 21 are of different sizes and are arranged according to the shape of the irregular part 1.

[0063] In this application, the axial direction refers to the direction of pressure applied by the split pressure head assembly 20. Typically, the main body 10 is cylindrical or cylindrical in shape, and the aforementioned axial direction is equivalent to the axial center direction of the main body 10. The circumferential direction refers to the circumferential direction surrounding the aforementioned axial direction.

[0064] The floating support platform 30 has a spherical or arc-shaped surface on the side away from the irregular part 1. The floating support platform 30 abuts against the main body 10 through the spherical or arc-shaped surface, thereby realizing the swingability of the floating support platform 30.

[0065] Preferably, the main body 10 is provided with an arcuate groove adapted to the spherical surface on one side of the floating support platform 30.

[0066] Alternatively, the main body 10 may have a flat surface on one side of the floating support platform 30, and the arc-shaped surface of the floating support platform 30 may abut against the flat surface of the main body 10 through line contact; or, the spherical surface of the floating support platform 30 may abut against the flat surface of the main body 10 through point contact.

[0067] In another embodiment, the hinge structure includes a steel ball disposed between the floating support platform 30 and the main body 10, and the floating support platform 30 and / or the main body 10 are provided with an arc groove adapted to the steel ball.

[0068] Referring to Figure 3, the split pressure head assembly 20 is cylindrical in shape with a central hole; the pressure head 21 is tile-shaped, and several pressure heads 21 are spliced ​​together to form a cylindrical body. The lengths of the several pressure heads 21 in the axial direction are different to adapt to the shape and structure of the irregular part 1.

[0069] The floating support platform 30 is provided with a plurality of support arms 31, each of which corresponds to a pressure dividing head 21. Preferably, in the circumferential direction, the support arm 31 is positioned at the center of its corresponding pressure dividing head 21, thereby achieving better force balance.

[0070] Furthermore, the number of pressure dividing heads 21 and support arms 31 is two, three, or four. Preferably, the support arms 31 are inclined toward the pressure dividing head 21, and the end face of the support arm 31 that contacts the pressure dividing head 21 is a convex arc surface.

[0071] Furthermore, the inner end faces of the support arm 31 and the pressure dividing head 21 are provided with mutually engaging limiting grooves 32 and locking points, which are used to limit the relative misalignment of the support arm 31 and the pressure dividing head 21 in the circumferential direction.

[0072] This embodiment also includes a bushing body 40. As shown in Figure 5, the bushing body 40 includes a sleeve portion 41 and a shaft portion 42 arranged coaxially. The sleeve portion 41 is disposed on the side close to the main body 10, and the shaft portion 42 is disposed away from the main body 10.

[0073] The floating support platform 30 is movably disposed within the cavity of the sleeve portion 41; the split pressure head assembly 20 is slidably mounted on the shaft portion 42 along the axial direction; as shown in Figure 8, the connection between the sleeve portion 41 and the shaft portion 42 is provided with an opening 44 that communicates the inside and outside of the cavity of the sleeve portion 41; the support arm 31 extends out from the opening 44 and abuts against the inner end of the pressure head 21.

[0074] Preferably, the end of the sleeve portion 41 is provided with a connecting flange 43, which is fixedly connected to the main body 10.

[0075] Referring to Figures 2 and 7, this embodiment also includes an anvil block 12, which is slidably disposed axially within the cavity of the sleeve portion 41 and between the floating support platform 30 and the main body 10.

[0076] Furthermore, the main body 10 is provided with a boss 11 extending into the cavity of the sleeve portion 41. The anvil block 12 is disposed between the boss 11 and the floating support platform 30. During press fitting, the main body 10 transmits pressure to the irregular part 1 through the boss 11, the anvil block 12, the floating support platform 30 (and its support arm 31), and the pressure dividing head 21.

[0077] Referring to Figure 6, this embodiment also includes an outer sleeve 50, which is fitted onto the outside of the shaft portion 42, forming an annular limiting cavity between the outer sleeve 50 and the shaft portion 42. The pressure dividing head 21 is slidably disposed within the annular limiting cavity along the axial direction, and the annular limiting cavity is used to limit the radial displacement of the pressure dividing head 21 in the shaft portion 42. The inner portion of the outer sleeve 50 is fitted onto the sleeve portion 41, covering the opening 44 and the support arm 31.

[0078] The fit between the inner circular surface of the inner side of the outer sleeve 50 and the outer circular surface of the sleeve portion 41 meets the positioning requirements, thereby achieving the radial positioning of the outer sleeve 50. This ensures the positioning accuracy, such as the coaxiality of the annular limiting cavity and the pressure dividing head 21.

[0079] Furthermore, it also includes a fastening bolt 51, and the outer sleeve 50 and the shaft body 42 are provided with through holes in the radial direction. After the fastening bolt 51 passes through the through holes in the outer sleeve 50 and the shaft body 42, it inherently connects the outer sleeve 50 and the shaft body 40.

[0080] Furthermore, a portion of the pressure dividing head 21 is provided with an elongated hole 22 through which the fastening bolt 51 passes. The pressure dividing head 21 is slidable relative to the fastening bolt 51 along the axial direction and within the range of the elongated hole 22.

[0081] Furthermore, the shaft portion 42 is a positioning shaft, that is, the coaxiality and outer diameter tolerance of the shaft portion 42 meet the positioning design requirements, and the irregular part 1 is provided with a positioning hole 1a; during processing, the front end of the shaft portion 42 extends into the positioning hole 1a, thereby ensuring the coaxiality of the split pressure head assembly 20 and the irregular part.

[0082] Referring to Figures 1 and 2, the device also includes a mounting base 60 for connecting to the stamping head of the stamping equipment; the mounting base 60 is provided with mounting holes, and the main body 10 is detachably inserted into the mounting holes.

[0083] Preferably, after the main body 10 is inserted into the mounting hole, it is locked and fixed by fastening screws 61.

[0084] The present invention can automatically adjust the relative position of each pressure head 21 according to the dimensional tolerance of the pressed end face of the irregular part, thereby realizing automatic compensation for dimensional tolerance. As a result, during pressing, the irregular part is subjected to more uniform force in the circumferential direction, avoiding being pressed off-center or tilted, and ensuring assembly quality and accuracy.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
