Description

Technical Field

[0001] The utility model relates to the technical field of component press-in equipment, in particular to a shaft sleeve centering press-in device. Background Art

[0002] During machining, it is often necessary to assemble the sleeve and the shaft. The operation is usually to fix the sleeve and insert the shaft into the hole of the sleeve. Manual assembly is troublesome, labor-intensive, and has low assembly efficiency. For this reason, automatic assembly is generally used. However, the automatic assembly method has high requirements on the accuracy of the automatic assembly device and the machining accuracy of the sleeve and the shaft. Otherwise, since both the shaft and the sleeve are rigid components, when there is a slight insertion deviation between the shaft and the sleeve hole wall, a rigid collision will occur, which will cause irreversible damage to the assembly of the sleeve and the shaft and the automatic assembly device. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a shaft sleeve centering press-in device in view of the current status of the prior art, so as to realize the precise assembly of the shaft sleeve and the shaft, and at the same time, reduce the assembly accuracy of the press-in device and the machining accuracy requirements of the shaft sleeve hole and the shaft.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a shaft sleeve centering press-in device, including a shaft seat and a positioning shaft installed on the shaft seat, characterized in that: the shaft seat moves up and down, and a shaft sleeve floating mechanism is arranged directly above the shaft seat, and the shaft sleeve floating mechanism includes a fixedly arranged reference block, a vertical sliding block located below the reference block, a transverse sliding block located below the vertical sliding block, and a clamping piece arranged on the lower side of the transverse sliding block for clamping the shaft sleeve, a vertically arranged vertical slide rail is formed on the vertical sliding block, a vertical slide groove adapted to the vertical slide rail is formed on the lower side wall of the reference block, the vertical sliding block is vertically slidably arranged on the lower side wall of the reference block, and the vertical sliding block is relatively arranged in the vertical direction There are two vertical fixed columns, and vertical positioning columns are respectively slidably arranged on the two vertical fixed columns, and the outer ends of the vertical positioning columns are abutted against the side walls of the reference block, and a vertical spring that abuts against the vertical positioning column is arranged in the vertical fixed column, and a horizontal sliding rail arranged horizontally is formed on the horizontal sliding block, and a horizontal sliding groove matched with the horizontal sliding rail is formed on the lower side wall of the vertical sliding block, and the horizontal sliding block is horizontally slidably arranged on the lower side wall of the vertical sliding block, and two horizontal fixed columns are relatively arranged in the horizontal direction of the horizontal sliding block, and horizontal positioning columns are respectively slidably arranged on the two horizontal fixed columns, and the outer ends of the horizontal positioning columns are abutted against the side walls of the vertical sliding block, and a horizontal spring that abuts against the horizontal positioning column is arranged in the horizontal fixed column.

[0005] As an improvement, the clamping member is a clamping cylinder, and a clamping head is arranged at the output end of the clamping cylinder.

[0006] As a further improvement, the outer ends of the transverse positioning column and the vertical positioning column are respectively hemispherical.

[0007] As a further improvement, the vertical sliding groove and the horizontal sliding groove are dovetail grooves respectively.

[0008] As a further improvement, a support platform for supporting the transverse sliding block is provided below the transverse sliding block.

[0009] Compared with the prior art, the advantages of the utility model are: during the process of assembling the shaft sleeve, the shaft is vertically installed on the shaft seat, and then the shaft sleeve is fixed by a clamp. After that, when the shaft seat moves upward, when the shaft and the shaft sleeve hole are in contact, the transverse sliding block will slide transversely along the longitudinal sliding block, and the longitudinal sliding block can slide longitudinally along the reference block to achieve a slight displacement change of the shaft sleeve, thereby facilitating the smooth insertion of the shaft into the shaft sleeve and completing the precise assembly of the shaft sleeve and the shaft. At the same time, since the shaft sleeve floating mechanism can float with the shaft sleeve laterally and longitudinally, the assembly accuracy of the pressing device is reduced, and the processing progress requirements for the shaft sleeve hole and the shaft wall are reduced.

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown, the shaft sleeve centering and pressing device in this embodiment includes a shaft seat 8 and a shaft sleeve floating mechanism.

[0015] The positioning shaft 7 is installed on the shaft seat 8, the shaft seat 8 moves up and down, and a shaft sleeve floating mechanism is arranged directly above the shaft seat 8.

[0016] The sleeve floating mechanism comprises a fixed reference block 1, a vertical sliding block 2 located below the reference block 1, a transverse sliding block 3 located below the vertical sliding block 2, and a clamping member 5 disposed on the lower side of the transverse sliding block 3 for clamping the sleeve 6. Preferably, the clamping member is a clamping cylinder, and a chuck is disposed at the output end of the clamping cylinder.

[0017] like Figure 2As shown, a vertically arranged vertical slide rail 21 is formed on the vertical sliding block 2, and a vertical slide groove matched with the vertical slide rail 21 is formed on the lower side wall of the reference block 1. The vertical sliding block 2 is vertically slidably arranged on the lower side wall of the reference block 1, and two vertical fixed columns 22 are relatively arranged in the vertical direction of the vertical sliding block 2. Vertical positioning columns 23 are respectively slidably arranged on the two vertical fixed columns 22, and the outer ends of the vertical positioning columns 23 are abutted against the side walls of the reference block 1. A vertical spring 24 abutting against the vertical positioning column 23 is arranged in the vertical fixed column 22.

[0018] Please refer to Figure 1 A transverse sliding rail 31 arranged transversely is formed on the transverse sliding block 3, and a transverse sliding groove matched with the transverse sliding rail 31 is formed on the lower side wall of the vertical sliding block 2. The transverse sliding block 3 is arranged on the lower side wall of the vertical sliding block 2 for transverse sliding. Two transverse fixing columns 32 are arranged opposite to each other in the transverse direction of the transverse sliding block 3. Transverse positioning columns 33 are respectively slidably arranged on the two transverse fixing columns 32. The outer ends of the transverse positioning columns 33 are abutted against the side walls of the vertical sliding block 2, and transverse springs abutting against the transverse positioning columns 33 are arranged in the transverse fixing columns 32.

[0019] Furthermore, in the embodiment of the utility model, the vertical sliding groove and the horizontal sliding groove are dovetail grooves respectively.

[0020] Furthermore, the outer ends of the transverse positioning column 33 and the vertical positioning column 23 are respectively hemispherical.

[0021] In addition, in the embodiment of the utility model, in order to achieve the supporting effect of the lateral sliding block 3 and improve the stability of the sleeve floating mechanism, a supporting platform 4 for supporting the lateral sliding block 3 may be provided below the lateral sliding block 3 .

[0022] In summary, during the assembly of the sleeve 6, the shaft 7 is vertically installed on the shaft seat 8, and then the sleeve 6 is fixed by the clamp 5. After that, the shaft seat 8 moves upward. When the shaft 7 and the sleeve 6 hole are in contact, the transverse sliding block 3 will slide transversely along the longitudinal sliding block 2, and the longitudinal sliding block 2 can slide longitudinally along the reference block 1 to achieve a slight displacement change of the sleeve 6, thereby facilitating the smooth insertion of the shaft 7 into the sleeve 6 and completing the precise assembly of the sleeve 6 and the shaft 7. At the same time, since the sleeve floating mechanism can float with the sleeve 6 transversely and longitudinally, the assembly accuracy of the pressing device is reduced, and the processing progress requirements for the sleeve hole and the shaft 7 wall are reduced.
