Description

Technical Field

[0001] The invention relates to the technical field of cable processing, and in particular to a cable terminal head hole enlarging and fixing device. Background Art

[0002] In the manufacturing and maintenance of cable terminals, hole enlargement is an important process used to increase the diameter of the through hole of the cable terminal so as to connect larger terminals or connectors. Traditional hole enlargement is usually performed on a benchtop drill press, and the cable terminal needs to be fixed on the drill press to ensure stability during the processing. However, existing benchtop drill presses have certain limitations when fixing cylindrical materials.

[0003] At present, the fixing process of benchtop drilling machines is mainly aimed at flat or regular-shaped workpieces, while there is a lack of dedicated fixing devices for cylindrical cable terminals. In this case, operators often need to use universal clamps or temporary fixing methods to fix the cable terminals. These methods are not only inefficient, but also lack stability, which can easily lead to the displacement of the cable terminals during processing, thus affecting the quality of hole expansion and the overall performance of the cable terminals.

[0004] In addition, the existing benchtop drilling machine fixing process is usually unable to adapt to the fixing requirements of cable terminals of different diameters. Due to the variety of cable terminal diameters, the universal clamps often cannot provide appropriate fixing force. Too much clamping force may damage the cable terminal, while too little clamping force cannot ensure the stability of the cable terminal during processing. Summary of the invention

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] The following describes a cable terminal head hole enlarging and fixing device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the cable terminal head hole enlarging and fixing device according to the embodiment of the present invention comprises: a base 1, a fixing frame 2, a clamping assembly and a driving assembly.

[0036] The base 1 is a basic platform of a bench-type drilling machine, and the fixing frame 2 is detachably connected to the base 1 so that different fixing frames 2 can be replaced, thereby being suitable for drilling different types of objects.

[0037] The clamping assembly is disposed on the fixing frame 2 . The clamping assembly has an assembly hole 401 . The assembly hole 401 is used to install and fix the cable 100 . The diameter of the assembly hole 401 is adjustable according to the diameter of the cable 100 .

[0038] Thus, the cable terminal head hole enlarging and fixing device of the embodiment of the present invention uses the assembly hole 401 of the clamping assembly to fix the cable 100, thereby achieving the overall fixation of the cable 100 and improving the stability of the terminal head of the cable 100 during the hole enlarging process. In addition, the diameter of the assembly hole 401 can be adjusted according to the diameter of the cable 100 to be suitable for fixing the terminal heads of cables 100 with different diameters, thereby improving the processing flexibility.

[0039] The driving assembly is arranged on the fixing frame 2, and the driving assembly is connected to the clamping assembly, and the driving assembly is used to adjust the diameter of the assembly hole 401 of the clamping assembly. It can be understood that the adjustment is performed through the driving assembly, thereby reducing the difficulty of operation, saving time and effort.

[0040] Furthermore, during the hole enlargement process of the cable 100 terminal head, a shim 21 is placed on the fixing frame 2 to place the terminal head on the shim 21 for hole enlargement, which not only plays a supporting role, but also protects the drilling machine (supporting structure on the table drilling machine such as the base 1 and the fixing frame 2). Figure 3 Shown is the location of the hole to be enlarged in the terminal head of the cable 100.

[0041] In some embodiments, Figure 1 and Figure 2 As shown, the clamping assembly includes a housing 3 and a plurality of telescopic members 4. The housing 3 is columnar, the telescopic members 4 are arranged in the housing 3, the plurality of telescopic members 4 are distributed around the axial direction of the housing 3 at intervals, the plurality of telescopic members 4 jointly define an assembly hole 401 located at the center thereof, and the telescopic members 4 are telescopic along the radial direction of the housing 3 to adjust the diameter of the assembly hole 401.

[0042] It is understandable that by adjusting the telescopic length of the telescopic member 4 , the diameter of the assembly hole 401 can be adjusted to meet the requirements of different cable 100 sizes.

[0043] Alternatively, if Figure 2As shown, the telescopic member 4 includes a spring 41 and a clamping block 42 . The spring 41 extends radially along the housing 3 . One end of the spring 41 is connected to the inner circumferential wall of the housing 3 , and the other end of the spring 41 is connected to the clamping block 42 .

[0044] It should be noted that when an external force is applied radially to the clamping block 42, the clamping block 42 moves toward the center and drives the spring 41 to stretch. When no external force is applied to the clamping block 42, the spring 41 contracts and drives the clamping block 42 to move outward.

[0045] In some embodiments, Figure 2 As shown, the inner end surface of the clamping block 42 is an arc-shaped concave surface, and an elastic pad (not shown in the figure) is attached to the inner end surface of the clamping block 42.

[0046] It is understandable that, since the cable 100 is a cylindrical object, the inner end surface of the clamping block 42 is designed as an arc-shaped concave surface, which helps to fit with the peripheral wall of the cable 100, thereby improving the clamping effect. In addition, the elastic pad on the inner end surface of the clamping block 42 can reduce the damage caused by the clamping block 42 to the skin of the cable 100.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the housing 3 includes an outer ring side plate 31 , a top plate 32 , a bottom plate 33 and connecting columns 34 .

[0048] The top plate 32 and the bottom plate 33 are spaced apart from each other, the top plate 32 is connected to the bottom plate 33 via a connecting column 34 , the end of the connecting column 34 is connected to the fixing frame 2 , and the outer ring side plate 31 is connected to the top plate 32 to form a supporting structure of the telescopic member 4 .

[0049] The top plate 32 and the bottom plate 33 are provided with corresponding through holes to facilitate the passage of the cable 100. The clamping block 42 is located between the top plate 32 and the bottom plate 33, the end surface of the clamping block 42 is in sliding contact with the top plate 32 and the bottom plate 33, and the end of the spring 41 is connected to the inner peripheral wall of the outer ring side plate 31, thereby improving the reliability of the movement of the clamping block 42.

[0050] In some embodiments, Figure 1 and Figure 2 As shown, the driving assembly includes an inner gear ring 5 and a plurality of transmission gears 6 meshing with the inner gear ring 5 .

[0051] The inner gear ring 5 is rotatably connected to the fixed frame 2, and the transmission gear 6 is rotatably connected to the fixed frame 2 through a rotating shaft, and a cam 7 is mounted on the rotating shaft of the transmission gear 6. There is a gap between the outer ring side plate 31 and the bottom plate 33, and the rotating shaft of the transmission gear 6 passes through the gap so that the cam 7 is located in the housing 3. The multiple cams 7 correspond to the multiple clamping blocks 42 one by one, and the outer end surface of the clamping block 42 is an arc-shaped convex surface, and the peripheral wall of the cam 7 is in sliding contact with the outer end surface of the clamping block 42.

[0052] Therefore, by rotating the inner gear ring 5, the inner gear ring 5 drives each transmission gear 6 to rotate, and the transmission gear 6 drives the cam 7 to rotate by rotating, thereby synchronously driving multiple clamping blocks 42 to move inward or outward to adjust the diameter of the assembly hole 401 (that is, to adjust the clamping degree of the cable 100).

[0053] Alternatively, if Figure 1 As shown, the driving assembly also includes a worm 8, a boss is provided on the fixed frame 2, and the worm 8 is matched on the boss through a bearing to achieve a rotatable connection between the worm 8 and the fixed frame 2. The outer peripheral wall of the inner gear ring 5 is provided with worm wheel teeth matched with the worm 8, so that the worm 8 rotates, and the worm 8 drives the inner gear ring 5 to rotate.

[0054] That is, the transmission mode of the worm gear 8 is used to drive the internal gear ring 5 to rotate, which has high precision and self-locking property. When the worm gear 8 is not rotated, the internal gear will not rotate, thereby improving the reliability of fixing the cable 100 during the expansion process of the cable 100.

[0055] Furthermore, if Figure 1 As shown, a handle 9 is provided at the end of the worm 8 , thereby improving the convenience for the operator to rotate the worm 8 .

[0056] In some embodiments, Figure 1 and Figure 2 As shown, the fixing frame 2 is composed of a plurality of connected support plates, and the support plates are provided with connecting holes for passing the cables 100. It can be understood that the fixing frame 2 adopts a frame structure, which is light in overall weight and low in cost.

[0057] In some embodiments, Figure 1 and Figure 2 As shown, an inverted T-shaped slot 101 is provided on the base 1, and a bolt 11 is provided between the base 1 and the fixing frame 2. The head of the bolt 11 is clamped in the slot 101, and the bolt 11 passes through the slot 101 and penetrates the support plate, and the nut mounted on the bolt 11 abuts against the support plate.

[0058] Thus, the base 1 and the fixing frame 2 are detachably connected by means of the bolts 11 . After tightening the nuts, the fixing frame 2 is fixed on the base 1 . After loosening the nuts, the fixing frame 2 can be removed from the base 1 .
