Description

Technical Field

[0001] The present invention belongs to the technical field of component hole opening, and particularly relates to a double-sided positioning punching mechanism. Background Art

[0002] At the present stage in the power industry, for opening holes in insulating sleeves on copper bars, a handheld punch is mainly used to open holes in the insulating sleeves. When opening holes, an operator holds the punch with one hand and a hammer with the other hand, and realizes hole opening by hitting the top of the punch. However, there are the following defects in using the punch for hole opening:

[0003] First, the safety is low. The operator is prone to accidentally injuring himself, and it is easy to hit his own hand by accident.

[0004] Second, for traditional punches, there are no positioning and alignment measures. After the insulating sleeve is punched, it is easy to be eccentric, and there is also a lack of a thimble limit function. The knocking force during punching cannot be controlled, which is easy to cause damage to the copper bar and leave deep scars on the copper bar.

[0005] Third, the economy is low. Traditional punches are integral. Once the cutting edge is damaged and it cannot cut the insulating sleeve, the whole punch can only be discarded and a new one needs to be purchased or processed, which cannot be recycled and causes waste.

[0006] Fourth, the versatility is poor. Traditional punches are integral, and matching punches need to be configured for various hole diameters.

[0007] Therefore, there is an urgent need for a positioning punching mechanism to improve the above technical defects. Summary of the Invention

[0008] In view of the problems existing in the prior art, the present invention provides a double-sided positioning punching mechanism. After using this positioning punching mechanism, the safety is high. The positioning punching mechanism has a special holding handle and is not on the part where the mechanism chips, so it will not cause damage to the operator. Moreover, the whole set of mechanism makes more use of labor-saving levers and is labor-saving; by using the positioning and alignment of the third threaded pin, the insulating sleeve will not be eccentric after punching. By using the thimble limit of the third threaded pin, the chip depth of the sleeve is guaranteed. After cutting the insulating sleeve, no scars will be left on the copper bar and no damage will be caused to the copper bar; the economy is high. The positioning punching mechanism adopts component assembly type, and each component can be replaced. Once damage occurs, it is not necessary to discard the whole set of mechanism, which greatly reduces the cost; the versatility is good. The sleeve in the punch assembly can be replaced separately according to different hole diameters, and the third threaded pin in the punch assembly can be replaced separately according to different chip depths. The chip depth is adjusted by the distance of the thimble limit.

[0048] In the embodiment, as Figure 11 and Figure 12As shown, the punch assembly 4 includes a threaded connector 4.1, a base 4.2, a threaded spring pin 4.3, a compression spring 4.4, a third threaded pin 4.5, a pressure relief plate 4.6, a sleeve 4.7, and a screw 4.8.

[0050] In the embodiment, further preferably, as Figure 1 shown, four handles 1.4 are provided, and every two of the handles 1.4 are symmetrically arranged on both sides of the fixing bracket 1.1.

[0051] In the embodiment, further preferably, two screws 4.8 are provided, and the two screws 4.8 are axially symmetrically arranged with respect to the sleeve 4.7.

[0052] In the embodiment, further preferably, as Figure 1 and Figure 2 shown, the two punch assemblies 4 are vertically arranged opposite to each other.

[0053] In the embodiment, further preferably, as Figure 2 shown, two tension springs 5 are provided, and the two tension springs 5 are respectively connected to both sides of the first linkage assembly 2 and the second linkage assembly 3.

[0054] In the embodiment, further preferably, both the second connecting plate 2.1 and the first crank arm 2.2 are double-layer plate structures.

[0055] The working process and working principle of the present invention are as follows:

[0056] Grip the two pairs of handles 1.4 on the double - hand - holding driving component 1, and use the power of making a fist to pull the handle 1.4 to drive the first connecting plate 1.2. The movement of the first connecting plate 1.2 pulls the two pairs of first crank arms 2.2. The first crank arms 2.2 drive the two pairs of second connecting plates 2.1 to make a rotational movement and overcome the pulling force of the tension spring 5. The second connecting plates 2.1 drive the punch assembly 4 to move up and down. There is a tip on the third threaded pin 4.5 for positioning and alignment. During the up - and - down movement of the punch assembly 4, the third threaded pin 4.5 first contacts the insulating sleeve on the surface of the copper busbar, and then the pressure - relief plate 4.6 and the sleeve 4.7 contact the insulating sleeve on the surface of the copper busbar. As the punch assembly 4 continues to move up and down, the sleeve 4.7 starts to cut the insulating sleeve. Due to the extrusion force, the pressure - relief plate 4.6 will be pushed in the opposite direction of the movement and compress the compression spring 4.4. The pressure - relief plate 4.6 is provided with a pressure - relief hole to reduce the pressure generated during the cutting of the sleeve 4.7. When the two third threaded pins 4.5 reach the top, the punch assembly 4 stops moving up and down and reversely stops the whole mechanism, completing the opening of the insulating sleeve on the surface of the copper busbar.

[0057] After the two hands are released, the tension spring 5 resets and pulls the two pairs of second connecting plates 2.1 to make a reverse rotational movement. The second connecting plates 2.1 pull the punch assembly 4. During the pulling of the punch assembly 4, the compression spring 4.4 resets and pushes the pressure - relief plate 4.6. The screw 4.8 stops after touching the bottom of the limit hole on the sleeve 4.7. The pressure - relief plate 4.6 resets and discharges the cut - off object; the second connecting plates 2.1 drive the two pairs of first crank arms 2.2, the first crank arms 2.2 drive the first connecting plate 1.2, and the first connecting plate 1.2 drives a pair of handles 1.4. After the first threaded pin 1.3 touches the bottom of the limit hole on the fixed bracket 1.1, the whole mechanism resets and is completed.

[0058] The above - mentioned are only the embodiments of the present invention. Therefore, it does not limit the patent scope of the present invention. Any equivalent structure made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is similarly included in the patent protection scope of the present invention.
