Description

Technical Field

[0001] This utility model relates to the field of copper busbar heat shrink tubing cutting technology, specifically to a copper busbar tubing cutting device. Background Technology

[0002] Because the heat shrink tubing for copper busbars is heat-shrinked before cutting, the traditional method involves workers using a measuring tape to draw lines and then cutting along those lines with a utility knife. This method of cutting the heat shrink tubing with a utility knife is not only inconvenient and prone to uneven cuts that affect the appearance, but it also carries the risk of workers cutting their fingers.

[0003] Furthermore, to improve the cutting smoothness of copper busbar heat shrink tubing and avoid the risk of workers' fingers being cut, some inventors have developed copper busbar tubing cutting devices. However, current copper busbar tubing cutting devices have complex structures and high manufacturing costs. For example, Chinese Patent Publication No. CN109500863A, entitled "A Heat Shrink Tubing Cutting Device," includes a base, a first support plate, a first threaded rod, a first copper busbar pressure plate, a first pressure plate knob, a second support plate, a second threaded rod, a second pressure plate knob, a first horizontal guide rail, a second horizontal guide rail, a first slider, a first hydraulic rod, a first blade support, a first blade, a second slider, a second hydraulic rod, a second blade support, a second blade, a third blade support, a fourth blade support, a third blade, a first sliding slider, a fourth blade, a second sliding slider, a moving rod, a third slider, a fourth slider, a third hydraulic rod, and a fourth hydraulic rod. Utility Model Content

[0004] The purpose of this invention is to provide a copper busbar sleeve cutting device that is not only easy to operate and ensures the flatness of the copper busbar heat shrink tubing during cutting, but also has a simple structure, is easy to manufacture, and can save manufacturing costs.

[0005] The technical solution of this utility model is: A copper busbar sleeve cutting device, comprising: Caliper, comprising two clamping arms; Two bases are fixed to the clamping arms in a one-to-one correspondence, and a copper busbar passage is formed between the two bases; Two cutting components, each corresponding to a base, include a movable part slidably mounted on the corresponding base, a sleeve cutter slidably mounted on the movable part, and a spring that drives the sleeve cutter to move toward the copper busbar outlet side; A push-pull component connects to the moving parts of the two cutting assemblies, pushing the moving parts to move. The specific use of a copper busbar sleeve cutting device according to this solution is as follows: Use a measuring tape to measure the cutting position of the heat shrink tubing; Pass the copper busbar (with the heat shrink tubing installed) through the copper busbar opening formed between the two bases and the clamping opening between the two clamping arms, align the tubing cutter with the cutting position, and adjust the width direction of the copper busbar to be roughly consistent with the movement direction of the moving part. The sleeve cutter of the two cutting components is moved to one side of the copper busbar by the push-pull mechanism (the sleeve cutter is separated from the copper busbar); the copper busbar is clamped by the two clamping arms of the caliper. Next, the sleeve cutters of the two cutting components are slowly pushed to the other side of the copper busbar by the push-pull mechanism. During this process, the springs of the two cutting components drive the sleeve cutters to press against the heat shrink tubing of the copper busbar, applying sufficient force to make the sleeve cutters cut into the heat shrink tubing and cut the heat shrink tubing. When the blades reach the two sides in the width direction of the copper busbar, there is downward pressure to cut off the heat shrink tubing at both ends in the width direction of the copper busbar, thus cutting the heat shrink tubing as a whole. This not only facilitates worker operation and ensures the flatness of the cut of the copper busbar heat shrink tubing, but also has a simple structure, is easy to manufacture, and can save manufacturing costs. Next, release the clamps, remove the equipment and place it in the designated position, then remove the cut-off excess sleeve by hand.

[0006] Preferably, the sleeve cutter includes a blade and a blade fixed to the end of the blade. A guide hole is provided on the moving part, and the blade is slidably disposed within the guide hole. A protrusion is provided on the end of the blade near the blade, and a spring is sleeved on the blade, resting against the moving part and the protrusion. This ensures smooth movement of the sleeve cutter and facilitates actual manufacturing.

[0007] Preferably, the cutter bar is equipped with a threaded adjusting nut, which is located on opposite sides of the moving part, and the adjusting nut is pressed against the moving part by the action of the spring. When dealing with copper busbars of different thicknesses, the position of the blade can be adjusted by tightening or loosening the adjusting nut to adapt to the cutting of heat shrink tubing of different thickness copper busbars.

[0008] Preferably, the base is provided with two parallel guide grooves, which are sequentially distributed along the axial direction of the tool holder. The moving component includes: Two rollers are set one-to-one in the two guide grooves of the corresponding base; The bearing is mounted on the roller and located within the corresponding guide groove; The guide holes are located on two rollers of the same moving component. This ensures smooth movement of the moving component and prevents jamming during movement.

[0009] Preferably, a bearing baffle is provided on one side of the guide groove, and a double-shaft connecting block is provided at one end of each of the two rollers of the same moving component. One end of each roller is connected to the double-shaft connecting block, and the bearing baffle and the double-shaft connecting block are located on opposite sides of the guide groove. The push-pull component is connected to the double-shaft connecting block. In this way, the two rollers can be connected as one unit by the double-shaft connecting block, and the bearing baffle restricts the position of the bearing, thereby ensuring the structural stability of the moving component and preventing the bearing from falling out of the guide groove.

[0010] Preferably, the blade is a round blade. A round blade is advantageous for cutting into the heat shrink tubing and severing it.

[0011] Preferably, the caliper includes a handle, and the push-pull member includes: The handlebar is located on the same side of the base as the stem, and a handle is also provided on the handlebar. Two pull rods correspond one-to-one with the moving parts. One end of the pull rod is hinged to the corresponding moving part, and the other end is hinged to the vertical handle. In actual operation, the worker holds the handle and moves the sleeve cutter of the two cutting components through the vertical handle and the two pull rods to facilitate operation; at the same time, it does not affect the clamping of the copper busbar by the caliper.

[0012] Preferably, a pull rod limiting seat is also provided on the side of the base near the handle, and the pull rod limiting seat has a limiting groove through which the pull rod passes. In this way, it can be ensured that the pull rod can move smoothly, thereby smoothly driving the sleeve cutter of the two cutting components to move.

[0013] Preferably, a predetermined distance is provided between the sleeve cutters of the two cutting components in the moving direction of the moving member. In this way, after the sleeve cutters of the two cutting components move to the outside of the copper busbar (for example, after cutting is completed), the collision between the two sleeve cutters can be effectively avoided.

[0014] Preferably, a blade limiting plate is provided on the side of the base near the copper busbar opening. The blade limiting plate includes a blade limiting surface, which is parallel to the moving direction of the moving component. The sleeve cutter is located near the blade limiting surface of the corresponding base. In this way, the blade can be limited by the blade limiting surface, effectively preventing blade rotation.

[0015] The beneficial effects of this utility model are as follows: During the movement of the sleeve cutter, the springs of the two cutting components drive the sleeve cutter to press against the heat shrink sleeve of the copper busbar, applying sufficient force to make the sleeve cutter cut into the heat shrink sleeve and cut the heat shrink sleeve; and when the blade reaches the two sides in the width direction of the copper busbar, there can be downward pressure to cut off the heat shrink sleeve at both ends in the width direction of the copper busbar, thereby cutting the heat shrink sleeve as a whole. It not only facilitates worker operation and ensures the flatness of the cut of the copper busbar heat shrink sleeve, but also has a simple structure, is easy to manufacture, and can save manufacturing costs.

Detailed Implementation

[0021] Specific Implementation Example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, a copper busbar sleeve cutting device includes a clamp 1, two bases 2, two cutting components 3, and a push-pull component 5.

[0022] The caliper 1 includes two clamping arms 1.1 and a clamping opening formed between the two clamping arms 1.1.

[0023] The base 2 corresponds one-to-one with the clamping arm 1.1. The base 2 is fixed to the corresponding clamping arm 1.1 by bolts, welding, or riveting. A copper busbar through-hole 4 is formed between the two bases 2.

[0024] The cutting assembly 3 corresponds one-to-one with the base 2. The cutting assembly 3 includes a movable part 3.1 slidably mounted on the corresponding base 2, a sleeve cutter 3.2 slidably mounted on the movable part 3.1, and a spring 3.3 that drives the sleeve cutter 3.2 to move toward the copper busbar outlet 4. The moving direction of the sleeve cutter 3.2 is perpendicular to the moving direction of the movable part 3.1.

[0025] The push-pull member 5 is connected to the moving parts 3.1 of the two cutting components 3, and the push-pull member 5 is used to push the moving parts 3.1 of the two cutting components 3 to move.

[0026] The specific use of the copper busbar sleeve cutting equipment in this embodiment is as follows. Use a measuring tape to measure the cutting position of the heat shrink tubing 7; Pass the copper busbar 6 (copper busbar with heat shrink tubing installed) through the copper busbar passage 4 formed between the two bases 2 and the clamping opening between the two clamping arms 1.1, so that the tubing cutter 3.2 is aligned with the cutting position, and adjust the width direction of the copper busbar to be roughly consistent with the movement direction of the moving part 3.1. The sleeve cutter 3.2 of the two cutting components 3 is moved to one side of the copper busbar by the push-pull component 5 (the sleeve cutter 3.2 is separated from the copper busbar); the copper busbar is clamped by the two clamping arms 1.1 of the clamp 1; Next, the sleeve cutters 3.2 of the two cutting components 3 are slowly pushed to the other side of the copper busbar by the push-pull component 5. During this process, the springs 3.3 of the two cutting components 3 drive the sleeve cutters 3.2 to press against the heat shrink tubing of the copper busbar, giving sufficient force to make the sleeve cutters 3.2 cut into the heat shrink tubing and cut the heat shrink tubing. When the blades 3.22 reach the two sides in the width direction of the copper busbar, there can be downward pressure to cut off the heat shrink tubing at both ends in the width direction of the copper busbar, thereby cutting off the heat shrink tubing as a whole. This not only facilitates worker operation and ensures the flatness of the cut of the copper busbar heat shrink tubing, but also has a simple structure, is easy to manufacture, and can save manufacturing costs. Next, release clamp 1, remove the device and place it in the designated position, then remove the cut excess sleeve by hand.

[0027] Specific embodiment two, such as Figure 1 , Figure 2 , Figure 3 As shown, a copper busbar sleeve cutting device includes a clamp 1, two bases 2, two cutting components 3, and a push-pull component 5.

[0028] The caliper 1 includes two clamping arms 1.1 and a clamping jaw formed between the two clamping arms 1.1. In this embodiment, the caliper 1 also includes a handle 1.2.

[0029] The base 2 corresponds one-to-one with the clamping arm 1.1. The base 2 is fixed to the corresponding clamping arm 1.1 by bolts, welding, or riveting. A copper busbar through-hole 4 is formed between the two bases 2.

[0030] The cutting assembly 3 corresponds one-to-one with the base 2. The cutting assembly 3 includes a movable part 3.1 slidably mounted on the corresponding base 2, a sleeve cutter 3.2 slidably mounted on the movable part 3.1, and a spring 3.3 that drives the sleeve cutter 3.2 to move toward the copper busbar outlet 4. The moving direction of the sleeve cutter 3.2 is perpendicular to the moving direction of the movable part 3.1.

[0031] The push-pull member 5 is connected to the moving parts 3.1 of the two cutting components 3, and the push-pull member 5 is used to push the moving parts 3.1 of the two cutting components 3 to move.

[0032] The specific use of the copper busbar sleeve cutting equipment in this embodiment is as follows. Use a measuring tape to measure the cutting position of the heat shrink tubing 7; Pass the copper busbar 6 (copper busbar with heat shrink tubing installed) through the copper busbar passage 4 formed between the two bases 2 and the clamping opening between the two clamping arms 1.1, so that the tubing cutter 3.2 is aligned with the cutting position, and adjust the width direction of the copper busbar to be roughly consistent with the movement direction of the moving part 3.1. The sleeve cutter 3.2 of the two cutting components 3 is moved to one side of the copper busbar by the push-pull component 5 (the sleeve cutter 3.2 is separated from the copper busbar); the copper busbar is clamped by the two clamping arms 1.1 of the clamp 1; Next, the sleeve cutters 3.2 of the two cutting components 3 are slowly pushed to the other side of the copper busbar by the push-pull component 5. During this process, the springs 3.3 of the two cutting components 3 drive the sleeve cutters 3.2 to press against the heat shrink tubing of the copper busbar, giving sufficient force to make the sleeve cutters 3.2 cut into the heat shrink tubing and cut the heat shrink tubing. When the blades 3.22 reach the two sides in the width direction of the copper busbar, there can be downward pressure to cut off the heat shrink tubing at both ends in the width direction of the copper busbar, thereby cutting off the heat shrink tubing as a whole. This not only facilitates worker operation and ensures the flatness of the cut of the copper busbar heat shrink tubing, but also has a simple structure, is easy to manufacture, and can save manufacturing costs. Next, release clamp 1, remove the device and place it in the designated position, then remove the cut excess sleeve by hand.

[0033] Furthermore, such as Figure 1 , Figure 2As shown, the sleeve cutter 3.2 includes a cutter bar 3.21 and a blade 3.22 fixed to the end of the cutter bar 3.21. A guide hole is provided on the moving member 3.1. The cutter bar 3.21 is slidably disposed within the guide hole. A protrusion 3.24 is provided on the end of the cutter bar 3.21 near the blade 3.22. A spring 3.3 is sleeved on the cutter bar 3.21, and the spring 3.3 abuts against the moving member 3.1 and the protrusion 3.24. This ensures that the sleeve cutter 3.2 can move smoothly and facilitates actual manufacturing. In this embodiment, the blade 3.22 is fixed to the protrusion 3.24; for example, the blade 3.22 is fixed to the protrusion 3.24 by bolts.

[0034] Furthermore, such as Figure 2 As shown, the cutter bar 3.21 is equipped with a threaded adjusting nut 3.23. The adjusting nut 3.23 and the spring 3.3 are located on opposite sides of the moving part 3.1. The adjusting nut 3.23 presses against the moving part 3.1 under the action of the spring 3.3. When dealing with copper busbars of different thicknesses, the position of the blade 3.22 can be adjusted by tightening or loosening the adjusting nut 3.23 to accommodate the cutting of heat shrink tubing of different thicknesses.

[0035] Furthermore, the tool holder 3.21 and the guide hole cannot rotate relative to each other. For example, the guide hole is a non-circular hole, and the cross-section of the tool holder 3.21 is adapted to the guide hole so that the tool holder 3.21 and the guide hole cannot rotate relative to each other; or the inner wall of the guide hole is provided with a keyway, and the outer surface of the tool holder 3.21 is provided with a strip-shaped protrusion that mates with the keyway, and the strip-shaped protrusion extends into the keyway so that the tool holder 3.21 and the guide hole cannot rotate relative to each other.

[0036] In one example, such as Figure 1 , Figure 2 , Figure 4 As shown, blade 3.22 is a circular blade 3.22. The circular blade 3.22 facilitates the cutting of the heat shrink tubing and cuts it off.

[0037] In another example, the blade 3.22 has a straight cutting edge, and the cutting edges of the blade 3.22 are distributed at an angle (not shown in the figure). Thus, the angled distribution of the cutting edges of the blade 3.22 also facilitates the blade 3.22 cutting into the heat shrink tubing and cutting the heat shrink tubing.

[0038] Furthermore, such as Figure 1 , Figure 2As shown, a blade limiting plate 2.3 is provided on the side of the base 2 near the copper busbar opening 4. The blade limiting plate 2.3 and the blade 3.22 are located on the same side of the base 2. The blade limiting plate 2.3 includes a blade limiting surface 2.4. The blade limiting surface 2.4 is parallel to the moving direction of the moving member 3.1. The blade limiting surface 2.4 extends along the moving direction of the moving member 3.1. The sleeve cutter 3.2 is close to the blade limiting surface 2.4 of the corresponding base 2. Specifically, the blade 3.22 is parallel to the blade limiting surface 2.4, and the blade 3.22 is close to the blade limiting surface 2.4 of the corresponding base 2. In this way, the blade 3.22 can be limited by the blade limiting surface 2.4, effectively preventing the blade 3.22 from rotating.

[0039] Furthermore, such as Figure 1 , Figure 4 As shown, a predetermined distance is provided between the sleeve cutters 3.2 of the two cutting components 3 in the moving direction of the moving member 3.1. Specifically, a predetermined distance is provided between the blades 3.22 of the two cutting components 3 in the moving direction of the moving member 3.1. In this way, after the sleeve cutters 3.2 of the two cutting components 3 move to the outside of the copper busbar (for example, after cutting is completed), the collision between the two sleeve cutters 3.2 can be effectively avoided.

[0040] A predetermined spacing is provided between the blades 3.22 of the two cutting components 3 in the moving direction of the moving component 3.1. The distance of this predetermined spacing is set according to actual needs. For example, when the blade 3.22 is a circular blade 3.22, the predetermined spacing is greater than 1 / 2 of the radius of the circular blade 3.22.

[0041] In one example, the spacing is set to be equal to 3.22 times the radius of the circular blade.

[0042] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, the push-pull component 5 includes a vertical handle 5.2 and two pull rods 5.3. The vertical handle 5.2 and the handle 1.2 are located on the same side of the base 2. The vertical handle 5.2 is also provided with a handle 5.1. The pull rods 5.3 correspond one-to-one with the moving parts 3.1. One end of the pull rod 5.3 is hinged to the corresponding moving part 3.1, and the other end of the pull rod 5.3 is hinged to the vertical handle 5.2. In actual operation, the worker holds the handle 5.1 and drives the sleeve cutter 3.2 of the two cutting components 3 to move through the vertical handle 5.2 and the two pull rods 5.3, which facilitates actual operation; at the same time, it will not affect the clamping of the copper busbar by the caliper 1.

[0043] Furthermore, such as Figure 3As shown, a pull rod limiting seat 8 is also provided on the side of the base 2 near the handle 5.2, and the pull rod limiting seat 8 corresponds one-to-one with the pull rod 5.3. The pull rod limiting seat 8 is provided with a limiting groove. The pull rod 5.3 passes through the limiting groove. In this way, it can be ensured that the pull rod 5.3 can move smoothly, thereby smoothly driving the sleeve cutter 3.2 of the two cutting components 3 to move.

[0044] Furthermore, the specific manner in which the movable component 3.1 is slidably disposed on the corresponding base 2 is as follows: In one implementation, such as Figure 1 , Figure 2 , Figure 3 As shown, the base 2 has two parallel guide grooves 2.1, which are sequentially distributed along the axial direction of the tool holder 3.21. The moving part 3.1 includes a bearing 3.12 and two rollers 3.11. The rollers 3.11 correspond one-to-one with the guide grooves 2.1. The rollers 3.11 are disposed within the corresponding guide grooves 2.1 of the base 2. The bearings 3.12 are disposed on the rollers 3.11 and are located within the corresponding guide grooves 2.1. In this embodiment, each roller 3.11 is provided with a bearing 3.12. Guide holes are provided on the two rollers 3.11 of the same moving part 3.1, that is, both rollers 3.11 of the same moving part 3.1 are provided with guide holes. The tool holder 3.21 passes sequentially through the guide holes on the two rollers 3.11 of the same moving part 3.1. The blade 3.22 is located on the same side of the two rollers 3.11 of the same moving part 3.1, and the protrusion 3.24 is also located on the same side of the two rollers 3.11 of the same moving part 3.1. The adjusting nut 3.23 is located on the same side of the two rollers 3.11 of the same moving part 3.1, and the two rollers 3.11 of the same moving part 3.1 are located between the protrusion 3.24 and the adjusting nut 3.23. One end of the spring 3.3 rests against the protrusion 3.24, and the other end of the spring 3.3 rests against the roller 3.11 adjacent to the protrusion 3.24. The adjusting nut 3.23 rests against the roller 3.11 under the action of the spring 3.3. In this way, the smooth movement of the moving part 3.1 can be ensured, and jamming during the movement of the moving part 3.1 can be avoided.

[0045] A bearing baffle 2.2 is provided on one side of the guide groove 2.1. A double-shaft connecting block 3.4 is provided at one end of the two rollers 3.11 of the same moving part 3.1. One end of the two rollers 3.11 is fixedly connected to the double-shaft connecting block 3.4. The bearing baffle 2.2 and the double-shaft connecting block 3.4 are located on opposite sides of the guide groove 2.1. The push-pull part 5 is connected to the double-shaft connecting block 3.4. Thus, the double-shaft connecting block 3.4 connects the two rollers 3.11 into one unit, and the bearing baffle 2.2 restricts the position of the bearing 3.12, thereby ensuring the structural stability of the moving part 3.1 and preventing the bearing 3.12 from dislodging from the guide groove 2.1.

[0046] In this embodiment, one end of the pull rod 5.3 is hinged to the dual-axis connecting block 3.4 of the corresponding moving part 3.1.

[0047] In one embodiment, a guide rail is provided on the base 2, and a sliding seat is provided on the guide rail. The moving part 3.1 is constituted by the sliding seat (not shown in the figure). A guide hole is provided on the sliding seat. One end of the spring 3.3 abuts against the protrusion 3.24, and the other end of the spring 3.3 abuts against the sliding seat. The adjusting nut 3.23 abuts against the sliding seat under the action of the spring 3.3. In this way, the smooth movement of the moving part 3.1 can be ensured, and jamming during the movement of the moving part 3.1 can be avoided. In this embodiment, one end of the pull rod 5.3 is hinged to the sliding seat of the corresponding moving part 3.1.

[0048] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
