[0002] In the process of mechanical installation, a first component and a second component are often encountered, the first component is provided with a plurality of first adapters, and the second component is provided with a plurality of second adapters arranged in a ring shape on the second component. When the second component is installed on the first component, an installation assembly is generally required to achieve this.

[0003] Specifically, the installation assembly comprises a connecting seat and a plurality of connecting pieces. The connecting seat is provided with a first connecting part and a plurality of connecting piece through holes arranged in a ring shape. The first connecting part is used to cooperate with the first adapter on the first component to fix the connecting seat on the first component. The connecting piece passes through the connecting piece through hole to cooperate with the second adapter on the second component to fix the second component on the connecting seat. In this way, the second component is installed on the first component through the installation assembly.

[0004] Because the distances between the plurality of second adapters of the second component produced by different manufacturers are not uniform. Therefore, one installation assembly is generally matched with one second component, that is, the application of the existing installation assembly is relatively limited and cannot adapt to the second components produced by different manufacturers.

[0005] Therefore, how to provide an installation assembly to adapt to second components produced by different manufacturers is still a technical problem that those skilled in the art need to solve urgently. CONTENT OF THE UTILITY MODEL

[0006] Therefore, in order to solve the above technical problems, the present application provides an installation assembly. The installation assembly comprises a connecting seat and a plurality of connecting pieces; the connecting seat is provided with a first connecting part and a ring-shaped clamping groove; the first connecting part is used to cooperate with the first adapter on the first component to fix the connecting seat on the first component; the connecting piece comprises a sliding block and a mounting part, the sliding block is slidingly clamped in the ring-shaped clamping groove to be able to slide along the ring-shaped clamping groove and not to be taken out of the ring-shaped clamping groove; the mounting part is arranged on the sliding block and is used to cooperate with the second adapter on the second component to install the second component.

[0007] Beneficial effects: Different from the prior art, in the present application, the first connecting part can fix the connecting seat on the first component. The sliding block can slide along the ring-shaped clamping groove to make the mounting part of the connecting piece move. Thus, according to the distance between the plurality of second adapters arranged in a ring shape on the second component, the mounting part can be correspondingly moved to align the mounting part with the second adapter on the second component, so as to install the second component on the mounting part. In this way, the installation assembly can adapt to second components produced by different manufacturers. BRIEF DESCRIPTION OF DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by the skilled in the art without making creative labor are within the scope of protection of the present application.

[0022] In combination Figures 1-2 , in reference Figures 3-7 , the mounting assembly 10 of the present application is used to mount the second component 30 to the first component 20.

[0023] The mounting assembly 10 comprises a connecting seat 100 and a plurality of connecting pieces 200. The connecting seat 100 is provided with a first connecting part 102 and an annular clamping groove 103. The first connecting part 102 is used to cooperate with a first adapter (not marked in the figure) on the first component 20, so as to fix the connecting seat 100 to the first component 20. The connecting piece 200 comprises a slider 210 and a mounting part 220, the slider 210 is slidingly clamped in the annular clamping groove 103, so as to be able to slide along the annular clamping groove 103. The mounting part 220 is arranged on the slider 210, and is used to cooperate with a second adapter (not shown in the figure) on the second component 30, so as to mount the second component 30.

[0024] In the above manner, the first connecting part 102 can be used to fix the connecting seat 100 to the first component 20. The slider 210 can slide along the annular clamping groove 103, so that the mounting part 220 of the connecting piece 200 moves along. Thus, according to the spacing between the plurality of second adapters arranged in an annular manner on the second component 30, the mounting part 220 can be correspondingly moved, so that the mounting part 220 is aligned with the second adapter on the second component 30, so as to mount the second component 30 to the mounting part 220. In this way, the mounting assembly 10 can adapt to the second components 30 produced by different manufacturers.

[0025] Optionally, as shown in FIG. 1, the first connecting part 102 comprises one or more of a first through hole 1021, a first clamping block (not shown in the figure) and a first clamping groove (not shown in the figure). Figures 1-11

A first threaded connecting part (not shown in the figure) is screwed through the first through hole 1021 and the first threaded hole to fix the connecting seat 100 to the first component 20.

[0027] In a second example, the first connecting part 102 comprises a plurality of first clamping blocks, and the first adapter on the first component 20 comprises a plurality of second clamping grooves (not shown in the figure) arranged corresponding to the plurality of first clamping blocks. The first clamping blocks are detachably clamped with the second clamping grooves to fix the connecting seat 100 to the first component 20.

[0028] In a third example, the first connecting part 102 comprises a plurality of first clamping grooves, and the first adapter on the first component 20 comprises a plurality of second clamping blocks (not shown in the figure) arranged corresponding to the plurality of first clamping grooves. The first clamping grooves are detachably clamped with the second clamping blocks to fix the connecting seat 100 to the first component 20.

[0029] For the convenience of description, in the following examples, the connecting structure of the first connecting part 102 and the first component 20 is taken as an example of the structure shown in the first example, but is not limited thereto.

[0030] Optionally, the mounting part 220 can comprise one or more of a screw rod, a third threaded hole, a third clamping block and a third clamping groove.

[0031] In a fourth example, the mounting part 220 is a screw rod, and the second adapter on the second component 30 is a fourth through hole (not shown in the figure). One end of the screw rod is connected with the sliding block 210, and the other end of the screw rod extends out of the annular clamping groove 103 from the opening end of the annular clamping groove 103 to pass through the fourth through hole. A compression nut is arranged on the screw rod and located at the end of the fourth through hole away from the sliding block 210 to compress the second component 30 and the connecting seat 100.

[0032] In a fifth example, the mounting part 220 is a third threaded hole, and the second adapter on the second component 30 is a fourth through hole (not shown in the figure). A third threaded connecting part is screwed through the fourth through hole and the third threaded hole to fix the second component 30 to the connecting seat 100.

[0033] In a sixth example, the mounting part 220 is a third clamping block, and the second adapter on the second component 30 is a fourth clamping groove (not shown in the figure). The third clamping block is detachably clamped with the fourth clamping groove to fix the second component 30 to the connecting seat 100.​

[0034] In the seventh example, the mounting portion 220 is a third clamping groove, and the second adapter portion on the second component 30 is a fourth clamping block (not shown in the figure). The third clamping groove and the fourth clamping block are detachably clamped to fix the second component 30 to the connecting seat 100.

[0035] For the convenience of description, in the following examples, the connection structure between the mounting portion 220 and the angle head shell 31 is taken as an example of the structure shown in the fourth example.

[0036] In an example, the first component is a bearing seat, and the second component is a shaft, but not limited thereto. In another example, the first component is a mechanical arm, and the second component is a base, but not limited thereto.

[0037] In the following, the first component 20 includes a spindle shell 21 and a driving spindle 22, and the second component 30 is an angle head.

[0038] Specifically, referring to Figures 1-2 , the driving spindle 22 is rotatably arranged in the spindle shell 21, and the first adapter portion is arranged on the spindle shell 21. The second component 30 can be an angle head, and the second component 30 includes an angle head shell 31 and a transmission spindle 32, and the second adapter portion is arranged on the angle head shell 31.

[0039] Among them, the mounting assembly 10 is used to mount the second component 30 to the spindle shell 21 on the machine tool, so that the angle head shell 31 is fixed to the spindle shell 21 and the transmission spindle 32 of the second component 30 is in driving connection with the driving spindle 22 in the spindle shell 21. The driving spindle 22 can protrude from the spindle shell 21 to be in driving connection with the transmission spindle 32. The connection mode of the driving spindle 22 and the transmission spindle 32 can refer to the prior art, which will not be described here.

[0040] In combination Figures 1-2 , referring to Figures 3-7 , specifically, the mounting assembly 10 includes a connecting seat 100 and a plurality of connecting pieces 200.

[0041] The connecting seat 100 is provided with a relief hole 101, a first connecting portion 102 and an annular clamping groove 103. The first connecting portion 102 is used to cooperate with the first adapter portion (not marked in the figure) on the first component 20 to fix the connecting seat 100 to the first component 20. The relief hole 101 is used for positioning, so that the transmission spindle 32 of the angle 30 can be in driving connection with the driving spindle 22. The annular clamping groove 103 is located outside the relief hole 101 and is arranged around the relief hole 101.

[0042] The connecting piece 200 comprises a sliding block 210 and a mounting portion 220. The sliding block 210 is slidingly connected in the annular clamping groove 103 and can slide along the annular clamping groove 103. The mounting portion 220 is arranged on the sliding block 210 and is used to cooperate with a second adapter (not shown in the figure) on the second component 30 to mount the second component 30.

[0043] In the above manner, the first connecting portion 102 can be used to fix the connecting seat 100 to the main shaft housing 21. The sliding block 210 can slide along the annular clamping groove 103 so that the mounting portion 220 of the connecting piece 200 moves accordingly. Thus, according to the distribution positions of the plurality of second adapters distributed around the transmission main shaft 32 on the angle head housing 31, the mounting portion 220 can be moved correspondingly so as to align the mounting portion 220 with the second adapter on the angle head housing 31, thereby mounting the second component 30 to the mounting portion 220. In this way, the mounting assembly 10 can be adapted to the second components 30 produced by different manufacturers.

[0044] Alternatively, as shown in Figures 1-11 The connecting seat 100 comprises a first connecting seat 110 and a second connecting seat 120 arranged in layers.

[0045] The avoiding hole 101 penetrates through the first connecting seat 110 and the second connecting seat 120 to form a first hole section 1011 in the first connecting seat 110 and a second hole section 1012 in the second connecting seat 120. The first connecting portion 102 is arranged on the first connecting seat 110, and the annular clamping groove 103 is located at an end of the second connecting seat 120 away from the first connecting seat 110.

[0046] The first connecting seat 110 is detachably connected with the second connecting seat 120. The end of the second connecting seat 120 close to the first connecting seat 110 is provided with a sliding block through hole 104. The sliding block through hole 104 is in communication with the bottom wall of the annular clamping groove 103. The sliding block through hole 104 is used for the sliding block 210 to pass through so that the sliding block 210 can enter and exit the annular clamping groove 103. The first connecting seat 110 covers the sliding block through hole 104 to prevent the sliding block 210 from entering and exiting the sliding block through hole 104.

[0047] In the above manner, at least the following two aspects have the following benefits.

[0048] Firstly, by detaching the second connecting seat 120 from the first connecting seat 110, the connecting piece 200 can be added or detached in the annular clamping groove 103 through the sliding block through hole 104, thereby increasing or decreasing the number of connecting pieces 200 on the second connecting seat 120. In this way, the number of connecting pieces 200 can be increased or decreased according to the number of second adapters in the second components 30 produced by different manufacturers, so that the number of connecting pieces 200 is consistent with the number of second adapters.

[0049] In the second aspect, the connecting piece 200 is dismounted, and the second component 30 is dismounted from the machine tool without dismounting the first connecting seat 110. Thus, the weight to be dismounted each time the second component 30 is replaced can be reduced, and the replacement of the second component 30 can be conveniently and quickly realized.

[0050] It should be noted that in other examples, the connecting piece 200 is dismounted, and the second component 30 is dismounted along with the connecting piece 200. At this time, the first connecting seat 110 does not need to be dismounted, and a tool holder (not shown in the figure) with a tool bit can be installed on the driving spindle 22. Thus, the second component 30 and the tool holder with the tool bit can be quickly replaced.

[0051] Optionally, as shown in Figures 1-11 The first connecting part 102 includes one or more of a first through hole 1021, a first clamping block (not shown in the figure), and a first clamping groove (not shown in the figure).

[0052] In the first example, the first connecting part 102 includes a plurality of first through holes 1021, and the first adapter part on the spindle housing 21 includes a plurality of first threaded holes (not shown in the figure) corresponding to the plurality of first through holes 1021. A first threaded connecting piece (not shown in the figure) is screwed through the first through hole 1021 and the first threaded hole to fix the first connecting seat 110 to the spindle housing 21.

[0053] In the second example, the first connecting part 102 includes a plurality of first clamping blocks, and the first adapter part on the spindle housing 21 includes a plurality of second clamping grooves (not shown in the figure) corresponding to the plurality of first clamping blocks. The first clamping block and the second clamping groove are detachably clamped and matched to fix the first connecting seat 110 to the spindle housing 21.

[0054] In the third example, the first connecting part 102 includes a plurality of first clamping grooves, and the first adapter part on the spindle housing 21 includes a plurality of second clamping blocks (not shown in the figure) corresponding to the plurality of first clamping grooves. The first clamping groove and the second clamping block are detachably clamped and matched to fix the first connecting seat 110 to the spindle housing 21.

[0055] For ease of illustration, in subsequent examples, the connection structure of the first connecting part 102 and the spindle housing 21 is taken as the structure shown in the first example.

[0056] Optionally, the mounting part 220 can include one or more of a screw rod, a third threaded hole, a third clamping block, and a third clamping groove.

[0057] In the fourth example, the mounting part 220 is a screw, and the second adapter on the angle head housing 31 is a fourth through hole (not shown in the figure). One end of the screw is connected to the slider 210, and the other end of the screw extends out of the annular groove 103 through the fourth through hole. A clamping nut is provided on the screw and located at the end of the fourth through hole away from the slider 210 to clamp the angle head housing 31 and the second connecting seat 120.

[0058] In the fifth example, the mounting part 220 is a third threaded hole, and the second adapter part on the angle head housing 31 is a fourth through hole (not shown in the figure). The third threaded connector passes through the fourth through hole and is threadedly connected to the third threaded hole to fix the angle head housing 31 to the second connecting seat 120.

[0059] In the sixth example, the mounting part 220 is a third locking block, and the second adapter part on the angle head housing 31 is a fourth locking slot (not shown). The third locking block and the fourth locking slot are detachably engaged to fix the angle head housing 31 to the second connecting seat 120.

[0060] In the seventh example, the mounting part 220 is a third slot, and the second adapter part on the angle head housing 31 is a fourth locking block (not shown). The third slot and the fourth locking block are detachably engaged to fix the angle head housing 31 to the second connecting seat 120.

[0061] For ease of explanation, in subsequent embodiments, the connection structure between the mounting part 220 and the angle head housing 31 is exemplified by the structure shown in the fourth illustration.

[0062] Optionally, such as Figures 1-11 As shown, since the transmission spindle 32 is commonly a tapered structure, the inner diameter of the second hole section 1012 can be smaller than the inner diameter of the first hole section 1011. This can reduce machining costs.

[0063] Optionally, such as Figures 1-11 As shown, the inner ring side of the annular slot 103 has a first annular sidewall 1031, and the outer ring side of the annular slot 103 has a second annular sidewall 1032.

[0064] An annular locking block 1033 is provided on the portion of the first annular sidewall 1031 and / or the second annular sidewall 1032 near the opening end of the annular groove 103. The annular locking block 1033 engages with the slider 210 to prevent the slider 210 from disengaging from the opening end of the annular groove 103.

[0065] Optionally, such as Figures 1-11 As shown, the slider 210 is provided with a first anti-torsion part 211 and a second anti-torsion part 212.

[0066] The first torsion-stopping portion 211 is guided by the first annular sidewall 1031, and the second torsion-stopping portion 212 is guided by the second annular sidewall 1032, so that the sliding block 210 can slide along the annular clamping groove 103. The first torsion-stopping portion 211 can be clamped by the first annular sidewall 1031 to prevent the mounting portion 220 arranged on the sliding block 210 from being twisted relative to the first annular sidewall 1031. The second torsion-stopping portion 212 can be clamped by the second annular sidewall 1032 to prevent the mounting portion 220 arranged on the sliding block 210 from being twisted relative to the second annular sidewall 1032.

[0067] In the above manner, since the sliding block 210 and the mounting portion 220 are not easy to be twisted relative to the first annular sidewall 1031 and the second annular sidewall 1032, the mounting portion 220 can be conveniently matched with the second adapter portion. For example, the nut can be conveniently screwed, but is not limited thereto.

[0068] The first torsion-stopping portion 211 can be in multi-point contact with the first annular sidewall 1031 to prevent the sliding block 210 from being twisted relative to the first annular sidewall 1031, and the second torsion-stopping portion 212 can be in multi-point contact with the second annular sidewall 1032 to prevent the sliding block 210 from being twisted relative to the second annular sidewall 1032. The multi-point contact is, for example, line contact, surface contact, or dispersed multiple point contact. It should be noted that in other examples, the first torsion-stopping portion 211 and the second torsion-stopping portion 212 can not be provided, and in this case, the sliding block 210 and the mounting portion 220 can be twisted relative to the first annular sidewall 1031 and the second annular sidewall 1032.

[0069] Optionally, as shown in Figures 1-11 The oil nozzle clamping groove 105 is connected to the inner sidewall of the first hole segment 1011, the outer sidewall of the first hole segment 1011, and the end surface of the first connecting seat 110 away from the second connecting seat 120. In this way, the oil nozzle (not labeled in the figure) on the driving spindle 22 can be clamped by using the oil nozzle clamping groove 105.

[0070] Optionally, as shown in Figures 1-11 The first connecting seat 110 is provided with a plurality of second threaded holes 106. The second connecting seat 120 is provided with a plurality of second through holes 107 corresponding to the plurality of second threaded holes 106. The first connecting seat 110 includes a plurality of second threaded connecting members (not shown), which are threadedly connected with the second threaded holes through the second through holes 107 to detachably fix the second connecting seat 120 to the first connecting seat 110. In this way, the second connecting seat 120 can be removed by removing the second threaded connecting members.

[0071] Optionally, as shown in Figures 1-11The first end of the second connecting seat 120 towards the first connecting seat 110 is sleeved and matched with the first end of the first connecting seat 110 towards the second connecting seat 120 through the first annular connecting part 130, so that the second hole segment 1012 is aligned with the first hole segment 1011. In this way, when the second connecting seat 120 is installed to the first connecting seat 110, the second hole segment 1012 can be quickly aligned with the first hole segment 1011.

[0072] Optionally, in an example, the first annular connecting part 130 is protrudingly arranged at the first end of the second connecting seat 120 towards the first connecting seat 110 and sleeved and matched with the first hole segment 1011.

[0073] Optionally, in another example, the first annular connecting part 130 is protrudingly arranged at the first end of the first connecting seat 110 towards the second connecting seat 120 and sleeved and matched with the second hole segment 1012.

[0074] Optionally, as shown in Figures 1-11 the second end of the second connecting seat 120 away from the first connecting seat 110 can be protrudingly arranged with a second annular connecting part 140, and the second annular connecting part 140 can be sleeved and matched with the angle head shell 31, so that the transmission main shaft 32 is aligned with the driving main shaft 22.

[0075] Optionally, as shown in Figures 1-11 the first connecting seat 110 is provided with a first pin hole 108, and the second connecting seat 120 is provided with a second pin hole 109. The first pin hole 108 and the second pin hole 109 are arranged staggered.

[0076] In the above manner, at least the following two aspects have beneficial effects.

[0077] Firstly, when the first connecting seat 110 is installed on the main shaft shell 21, the first pin can be used to nail the main shaft shell 21 through the first pin hole 108, so as to form a first nail mark on the main shaft shell 21. When the first connecting seat 110 is reinstalled after being removed later, the installation position of the first connecting seat 110 can be positioned by the formed first nail mark, so as to install the first connecting seat 110 more quickly.

[0078] Secondly, when the second connecting seat 120 is installed on the first connecting seat 110, the second pin can be used to nail the first connecting seat 110 through the second pin hole 109, so as to form a second nail mark on the first connecting seat 110. When the second connecting seat 120 is reinstalled after being removed later, the installation position of the second connecting seat 120 can be positioned by the formed second nail mark, so as to install the second connecting seat 120 more quickly.

[0079] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which is made by using the content of the present application specification and drawings, is also included in the patent protection scope of the present application.
