[0033] Hereinafter, possible embodiments of the assembly tool 10 according to the present application will be described by way of example with reference to the accompanying drawings.

[0034] As Figure 1 , Figure 2The assembly tool 10 in the application is used for assembling the pin 30 into the mounting hole 41 on the conical surface of the inner cavity of the part 40 under the guidance of the guide sleeve 20. The assembly tool 10 comprises a punch body 100 and a depth identifier 200. The punch body 100 is provided with a punch end 121 at one end, and the punch end 121 is matched with the guide hole of the guide sleeve 20. The depth identifier 200 is in the form of a cylindrical sleeve and is sleeved on the punch body 100 and is in sliding connection with the punch body 100 along the extension direction of the punch body 100. The position of the depth identifier 200 on the punch body 100 is set such that when the punch end 121 is in abutment with the pin 30 after extending into the guide hole, the depth identifier 200 is in abutment with the guide sleeve 20. When the pin 30 is assembled to the predetermined assembly depth in the mounting hole 41, the guide sleeve 20 pushes the depth identifier 200 to slide to the predetermined position. Thus, by sleeving the depth identifier 200 which can slide on the punch body 100, the assembly depth of the pin 30 in the mounting hole 41 can be determined by the position of the depth identifier 200 pushed by the guide sleeve 20 when the pin 30 is assembled, and the pin 30 can be determined to have been assembled to the predetermined assembly depth in the mounting hole 41 when the depth identifier 200 is pushed by the guide sleeve 20 to slide to the predetermined position. Thus, the assembly efficiency can be improved and the assembly quality can be ensured.

[0035] In some embodiments, as shown in Figure 2 The punch body 100 comprises a handle 110 and a punch 120. The handle 110 is provided with a hand holding portion 111, the punch 120 is arranged at one end of the handle 110, and the punch end 121 is arranged at the end of the punch 120 away from the handle 110. Thus, the user can conveniently operate the assembly tool 10.

[0036] In some embodiments, as shown in Figure 2 The punch 120 is detachably connected with the handle 110. Thus, when the punch 120 is worn out or the model of the mounting hole 41 and the pin 30 is changed, the punch 120 can be replaced, so that the adaptation range of the assembly tool 10 can be improved.

[0037] In some embodiments, as shown in Figure 2 One end of the handle 110 is provided with a first connecting end 112, and the punch 120 is provided with a second connecting end 122 towards the end of the handle 110. The first connecting end 112 is threadedly connected with the second connecting end 122. Thus, by threadedly connecting the first connecting end 112 with the second connecting end 122, the connection structure of the punch 120 and the handle 110 can be simplified, and the punch 120 can be conveniently replaced.

[0038] In some embodiments, the first connecting end 112 and the second connecting end 122 are snap-fit connected.

[0039] In some embodiments, as shown in Figure 2As shown, the second connecting end 122 is provided with a ring-shaped flange 123 protruding from the outer circumferential surface of the first connecting end 112; the inner circumferential surface of the depth identifier 200 has a diameter greater than that of the ring-shaped flange 123, and the depth identifier 200 is provided with a first limiting portion 211 and a second limiting portion 221 at two ends thereof, the first limiting portion 211 is in abutment with the outer circumferential surface of the first connecting end 112, and the second limiting portion 221 is in abutment with the outer circumferential surface of the second connecting end 122, and the ring-shaped flange 123 is arranged between the first limiting portion 211 and the second limiting portion 221. Thus, by arranging the first limiting portion 211 and the second limiting portion 221 on the depth identifier 200, the ring-shaped flange 123 is arranged between the first limiting portion 211 and the second limiting portion 221, so that the sliding range of the depth identifier 200 can be limited by the abutment between the ring-shaped flange 123 and the first limiting portion 211 and the second limiting portion 221.

[0040] In some embodiments, as shown in Figure 2 As shown, the depth identifier 200 includes a cylindrical first component 210 and a second component 220, and the first component 210 and the second component 220 are threadedly connected at opposite ends. Thus, by arranging the depth identifier 200 as a first component and a second component that can be threadedly connected, the installation and disassembly of the depth identifier 200 can be facilitated.

[0041] In some embodiments, as shown in Figure 2 As shown, the assembly tool 10 further includes an elastic member 300 for driving the depth identifier 200 to slide towards the punch end 121. Thus, by driving the depth identifier 200 to slide towards the punch end 121 by the elastic member 300, it can be ensured that the depth identifier 200 always abuts against the guide sleeve 20 when the punch end 121 is driven to assemble the pin 30. Thus, the accuracy of indicating the assembly depth of the pin 30 by the depth identifier 200 can be improved.

[0042] In some embodiments, as shown in Figure 2 As shown, the elastic member 300 is a spring sleeved on the punch body 100. Thus, by selecting a spring sleeved on the punch body 100 as the elastic member 300, the structure of the elastic member 300 can be simplified, and the stability of the elastic member 300 can be improved.

[0043] In some embodiments, as shown in Figure 2 As shown, the elastic member 300 is arranged at a position corresponding to the inner circumferential surface of the depth identifier 200, one end of the elastic member 300 abuts against the depth identifier 200, and the other end abuts against the punch body 100. Thus, the elastic member 300 can be hidden in the depth identifier 200, and the appearance of the assembly tool 10 can be more concise.

[0044] In some embodiments, as shown in Figure 2As shown, the punch body 100 is provided with an abutment portion 113, which abuts against the depth marker 200 when it slides to a predetermined position. Therefore, by having the depth marker 200 abut against the abutment portion 113 when it slides to the predetermined position, the depth marker 200 can be limited when the pin 30 is inserted into the mounting hole 41 to a predetermined assembly depth. This limits the assembly tool 10, preventing the punch end 121 from continuing to drive the pin 30 into the mounting hole 41. This improves the installation accuracy of the pin 30 and reduces the operational difficulty of the assembly tool 10.

[0045] In some embodiments, a scale is provided on the outer peripheral surface of the punch body 100 at the position corresponding to the depth marker 200 along the extension direction of the punch body 100, and the scale corresponding to the end of the depth marker 200 away from the punch end 121 corresponds to the depth of the pin 30 in the mounting hole 41.

[0046] The above description provides an exemplary description of possible embodiments of the assembly tool 10. Below, with reference to the accompanying drawings, a detailed description of the specific structure of the assembly tool 10 in this application will be given in a particular embodiment.

[0047] Figure 1 This is a schematic diagram showing the usage state of the assembly tool 10 in this application. Figure 1 As shown, the assembly tool 10 in this application is used to insert the pin 30 into the part 40 with the assistance of the guide sleeve 20. Specifically, the part 40 is a rotating part, and the inner surface of the part 40 has a conical surface with a plurality of circular mounting holes 41. The guide sleeve 20 is cylindrical, and a guide hole is provided inside the guide sleeve 20. The size of the guide hole is adapted to the diameter of the mounting hole 41. The pin 30 is cylindrical, and the diameter of the pin 30 is adapted to the diameter of the mounting hole 41. Thus, the guide hole can be aligned with the mounting hole 41, so that after the pin 30 is placed in the guide hole, the assembly tool 10 can be used to drive the pin 30 to move into the mounting hole 41, so that the pin 30 can be inserted into the mounting hole 41 to a predetermined installation depth under the guidance of the guide hole.

[0048] Figure 2 for Figure 1 A partial cross-sectional view of the assembly tool 10. (See attached diagram.) Figure 2 As shown, the assembly tool 10 includes a punch body 100, a depth indicator 200, and an elastic element 300. One end of the punch body 100 has a punch end 121, which is adapted to the guide hole of the guide sleeve 20. The depth indicator 200 is cylindrically sleeved on the punch body 100 and slidably connected to the punch body 100 along its extension direction. When assembling the pin 30 using the assembly tool 10, the depth indicator 200 can indicate the assembly depth of the pin 30.

[0049] As shown in Figure 2 the punch body 100 is cylindrical as a whole, comprising a handle 110 and a punch 120. The handle 110 is provided with a hand-holding portion 111 for facilitating user holding. One end of the handle 110 is provided with a first connecting end 112, which has a smaller diameter than the handle 110, so that a stepped abutting portion 113 is formed at the connecting position of the first connecting end 112 and the handle 110. The punch 120 is provided with the punch end 121 at one end and a second connecting end 122 at the other end. The second connecting end 122 is threadedly connected with the first connecting end 112, so that the axis of the handle 110 coincides with that of the punch 120. The second connecting end 122 is provided with an annular flange 123 on the outer circumferential surface near the end, which has a larger diameter than the first connecting end 112. Thus, after the first connecting end 112 and the second connecting end 122 are threadedly connected, the annular flange 123 protrudes from the outer circumferences of the first connecting end 112 and the second connecting end 122, so as to limit the first limiting portion 211 and the second limiting portion 221 described below.

[0050] As shown in Figure 2 the depth identifier 200 is cylindrically sleeved on the punch body 100 and located at the position corresponding to the first connecting end 112 and the second connecting end 122. The inner diameter of the depth identifier 200 is larger than the diameter of the annular flange 123, so that the depth identifier 200 can slide at the position where the first connecting end 112 and the second connecting end 122 are connected. The depth identifier 200 is provided with the first limiting portion 211 at one end facing the handle 110 and the second limiting portion 221 at the other end facing the punch 120. The inner diameter of the first limiting portion 211 is smaller than the inner diameter of the depth identifier 200, so that the first limiting portion 211 is in close contact with the outer circumference of the first connecting end 112. The inner diameter of the second limiting portion 221 is smaller than the inner diameter of the depth identifier 200, so that the second limiting portion 221 is in close contact with the outer circumference of the second connecting end 122. The annular flange 123 is arranged between the first limiting portion 211 and the second limiting portion 221, so that the sliding range of the depth identifier 200 is limited by the abutment between the annular flange 123 and the first limiting portion 211 and the second limiting portion 221.

[0051] As shown in Figure 2 the elastic member 300 is a spring, which is sleeved on the punch 120 and located in the depth identifier 200. One end of the spring is in abutment with the annular flange 123, and the other end is in abutment with the second limiting portion 221, so as to push the depth identifier 200 to slide towards the punch end 121.

[0052] As shown in Figure 2As shown, the depth identifier 200 is divided into a first part 210 and a second part 220 in the axial direction, the first part 210 and the second part 220 are threadedly connected at opposite ends, a first limiting part 211 is arranged on the first part 210, and a second limiting part 221 is arranged on the second part 220. Thus, when installing, the first part 210 can be sleeved into the first connecting end 112 first, then the first connecting end 112 and the second connecting end 122 are threadedly connected, then the elastic member 300 is sleeved on the punch 120, and finally the second part is sleeved on the punch 120, so that the second part is threadedly connected with the first part, and the two ends of the elastic member 300 are respectively abutted with the annular flange 123 and the second limiting part 221.

[0053] From the above, when the pin 30 is assembled by using the assembly tool 10, the guide hole in the guide sleeve 20 can be first butted with the mounting hole 41 on the part 40, and then the pin 30 is placed in the guide hole. The punch end 121 is inserted into the guide hole by using the assembly tool 10, so that the depth identifier 200 abuts against the guide sleeve 20. The assembly tool 10 is operated to drive the pin 30 to be inserted into the mounting hole 41 under the guidance of the guide hole, and when the depth identifier 200 abuts against the abutting part 113, it is determined that the pin 30 reaches the predetermined assembly depth in the mounting hole 41. Thus, the installation of the pin 30 is completed.

[0054] It should be noted that the above is only the preferred embodiment of the present application and the technical principle applied. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the protection scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and more other equivalent embodiments can be included without departing from the concept of the present application, and all belong to the protection scope of the present application.
