The copper plate is connected with the electric fittings, and the copper plate is connected with the copper plate through screw rods with assembly holes. In order to improve the insulation safety of the copper plate, a heat shrinkage pipe needs to be sleeved at the part outside the connecting part. The normal operation is that after the thermal shrinkage pipe is sleeved, the thermal shrinkage pipe at the assembly hole is cut to leak the assembly hole, the cutting position of the copper plate is positioned at two sides of the assembly hole formed in the thermal shrinkage pipe, after the thermal shrinkage pipe is sleeved on the copper plate, the thermal shrinkage pipe part covered outside the assembly hole is required to be cut, so that the assembly hole is displayed and used for connecting and assembling the copper plate.

At present, when the splitting operation of the heat shrink tube is carried out, the copper plate sleeved with the heat shrink tube is usually placed on a horizontal operation platform, then the side edge of the copper plate is attached to the splitting position outside the assembly hole by using a ruler manually (as shown in fig. 3), then an operator presses the ruler and the copper plate by one hand, and the splitting operation of the heat shrink tube is carried out along the side edge of the ruler by using a cutter by the other hand. The splitting operation of the heat shrink tube requires that both sides of the assembly hole are split along the circumferential direction (shown in fig. 4), so that the assembly hole can be displayed.

When the current manual operation is performed, the heat shrinkage tube covers the copper plate assembly holes, so that the placement position of the ruler is difficult to determine, the left and right deviation or cutting deviation (shown by a dotted line in fig. 5) of the cutting position and the assembly Kong Cunzai is caused, and the insulativity of the copper plate is influenced after the copper plate is connected. And because need cut along the circumference of copper plate (shown in fig. 7) when cutting, and copper plate then is sheet structure, can the ruler operate as the cutting benchmark when its lateral wall cuts, and when cutting of side, because its is later less, the ruler can not laminate, therefore at present will copper plate's lateral wall straight line cutting accomplish the back, tear the operation (shown by the arrow in fig. 6) with side department, and can cause when tearing and tear by the shrink tube part of cutting and lead to the shrink tube damage, also influence copper plate post-connection's insulating nature, at the same time above-mentioned manual work heat operation efficiency to the shrink tube is lower.

Detailed Description

In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 11, the splitting positions of the copper plates 10 are located at two sides (shown in fig. 5) of the assembly holes 10a formed in the copper plates, and the splitting operation of the heat shrink tube is performed manually at present, as shown in fig. 4, by using a ruler as a reference. In order to solve the problems that the existing manual fracturing operation is low in efficiency, the manual fracturing has the defects that the cutting size is not standard, the heat shrinkage tube at the thinner side edge of the copper plate is difficult to realize smooth fracturing and needs to be torn, the application designs a fracturing device to solve the problems.

Specifically, the splitting device comprises a clamping mechanism for detachably clamping the copper plate 10 along the circumferential direction, and a rotating mechanism which is connected with the clamping mechanism and drives the copper plate 10 to axially rotate. When carrying out the fracturing operation of copper plate pyrocondensation pipe, at first through clamping mechanism treats the position department of fracture with the copper plate centre gripping, then rethread slewing mechanism carries out circumference rotation to clamping mechanism and copper plate whole, and at this pivoted in-process, use clamping mechanism as the fracture benchmark, can carry out continuous fracturing operation to lateral wall (surface) and the side department of copper plate, solve present manual work and can not adopt the ruler and carry out the problem that the side fracturing operation led to the fact the pyrocondensation pipe to tear the damage, clamping mechanism also is difficult for causing the position skew of fracture benchmark and copper plate in the operation of present manual work subsides ruler simultaneously to and continuous fracturing can improve the operating efficiency of this operation under the rotation state.

Specifically, as shown in fig. 8, the clamping mechanism includes clamping plates 1 attached to each side wall of the copper plate 10 and having the same width as the cutting position, and two side walls of the clamping plates can be used as references for cutting the heat-shrinkable tube. The two ends of the clamping plate 1 on each side are respectively extended with a side end plate 11 for coating the side edge of the copper plate 10. The symmetrical clamping plates 1 can be attached to each side surface and side end of the copper plate by the side end plates 11 extending from the two ends of the clamping plates, so that the bidirectional clamping effect on the copper plate can be realized. In order to avoid contact interference of the two side clamping plates 1, as shown in fig. 8, the length of each side end plate 11 is less than half of the thickness of the side edge of the copper plate 10, so that after the two side clamping plates 1 clamp the two side walls of the copper plate in a fitting manner, the respective side end plates 11 are not contacted in a fitting and cladding state at the side ends of the copper plate, and clamping interference of the two side clamping plates 1 is avoided.

In order to achieve the positioning and clamping of the double-sided clamping plate 1 and the copper plate (specifically, the clamping plate 1 is clamped at the position where the heat shrinkage pipe needs to be cut, and then the cutting operation of the heat shrinkage pipe can be accurately performed by taking two side edges of the heat shrinkage pipe as the two side edges), positioning protrusions 12 which can be embedded into the assembly holes 10a are arranged on the inner wall of each side of the clamping plate 1. Because the heat shrinkage pipe is a thinner rubber pipe, after the heat shrinkage pipe is sleeved on the copper plate, the position of the assembly hole 10a can be obtained through finger touch, and then the positioning protrusion 12 on the clamping plate 1 is embedded into the assembly hole 10a to a certain depth (preferably 1-2 mm), so that the clamping and positioning of the clamping plate 1 and the copper plate are realized. After positioning, the clamping plate 1 is positioned at the position where the heat shrinkage pipe is cut, and then the cutting operation of the heat shrinkage pipe can be realized based on the side edge of the clamping plate 1.

Specifically, as shown in fig. 10, the rotating mechanism includes an arc plate 2 connected to the outer wall of the clamping plate 1 at each side, the outer side of the arc plate 2 is provided with a positioning ring 3 in a circumferential rotation manner, the arc plate 2 and the positioning ring 3 are preferably of an arc sliding rail matching structure, and the arc plates 2 at two sides drive the clamping plate 1 and the copper plate to rotate circumferentially in the positioning ring 3. In the rotating state, the continuous cutting operation of the copper plate circumference can be realized on the heat shrinkage tube by manually using the cutter along the clamping plate 1 and the side end plate 11 as a reference. In order to facilitate the assembly of the splitting device and the copper plate, as shown in fig. 8, the positioning ring 3 has a half-hinge structure, so that the assembly and the disassembly of the copper plate can be realized. For further improving the convenience of operation, as shown in fig. 8, the other end department that corresponds with the articulated end is provided with the magnetism and inhales the piece, and after laminating copper plate and grip block 1 assembly, can realize the closure of location ring 3 through the magnetism and inhale the piece, realize the centre gripping fastening of grip block 1 and copper plate, can rotate the copper plate to realize the circular cutting operation to the pyrocondensation pipe according to grip block 1 side. The fastening closure of the positioning ring 3 can also be achieved by providing a connecting screw (not shown in the figures).

In order to facilitate the integral fixation of the splitting device, the hinged end of the positioning circular ring 3 is preferably fixed on the side wall of the operating table 6, so that the assembly and splitting operation of the copper plate are realized.

The principle of the application is as follows: when the splitting operation of the copper plate heat shrinkage tube is carried out, firstly, the assembly hole of the copper plate is searched by fingers, the heat shrinkage tube is pressed into the assembly hole, the position of the assembly hole is displayed, then the copper plate is embedded into the positioning circular ring, in the process of closing the positioning circular ring, the positioning bulge 12 on the inner side of the clamping plate 1 is embedded into the assembly hole 10a to continuously close the positioning circular ring 3 and realize complete closing through the magnetic attraction block, the copper plate is driven to rotate after closing, and the cutter is used for realizing the continuous splitting operation of the heat shrinkage tube along the side edge annular direction of the clamping plate 1
