Description

Technical Field

[0001] This utility model relates to the field of wire stripping machine technology, specifically a wire stripping machine with easily replaceable blades. Background Technology

[0002] In the field of wire processing, wire stripping machines are key equipment for stripping the insulation layer of wires. Current technologies for replacing the blades and blade holders in wire stripping machines generally suffer from problems such as cumbersome operation, insufficient positioning accuracy, and poor safety. Traditional equipment often uses screws to fix the blade holder and blade, requiring tools to unscrew them during replacement, taking 2-3 minutes per change, severely impacting production efficiency. Furthermore, the lack of an efficient guiding structure makes the blade holder prone to lateral displacement during installation, causing quality problems such as skewed stripping cuts and insulation damage. In addition, existing snap-fit ​​structures rely on only a single locking method, posing a safety hazard of accidental blade holder detachment under high-speed operation or vibration conditions, failing to meet the reliability requirements of automated production lines.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a wire stripper that facilitates the replacement of the blade 501. It includes a main body 101, a blade holder 401 mounted on the main body 101, and a blade 501 detachably mounted on the blade holder 401. It also includes a quick-change device 201 for quick replacement of the blade holder 401. The quick-change device 201 includes a snap-fit ​​structure 301 disposed on the main body 101 and a mating structure disposed on the blade holder 401. The snap-fit ​​structure 301 and the mating structure are detachably connected. The blade holder 401 can be quickly disassembled and installed by pressing.

[0025] In this embodiment, during installation, the tool holder 401 is aligned with the installation position on the main body 101, and pressure is applied along the guide structure 901 (slide rail and slide groove). At this time, the elastic latching arm 801 provided on the main body 101 undergoes elastic deformation due to the compression of the tool holder 401's mating structure, and the protrusion 1301 at its free end slides along the inclined surface of the groove of the mating structure. When the tool holder 401 moves to the preset position, the protrusion 1301 of the elastic latching arm 801 precisely engages in the groove of the mating structure, achieving mechanical locking. Simultaneously, the spring (elastic reset member 701) located between the main body 101 and the tool holder 401 is gradually compressed during the movement of the tool holder 401, forming an elastic preload towards the main body 101, ensuring that the tool holder 401 and the main body 101 remain tightly fitted.

[0026] The quick-change device 201 also includes an elastic reset member 701 disposed between the main body 101 and the tool holder 401. The elastic reset member 701 is in a compressed state when the tool holder 401 is installed in place, providing the tool holder 401 with an elastic force toward the main body 101.

[0027] In this embodiment, when disassembling the tool holder 401, only a pressing force in the same direction as the installation is applied to the tool holder 401, compressing the spring and causing the elastic latch arm 801 to elastically deform again, causing the protrusion 1301 to disengage from the slot. At this time, under the action of the spring's restoring force, the tool holder 401 quickly pops out along the guide structure 901, completing tool-free quick disassembly.

[0028] Furthermore, the buckle structure 301 includes at least one elastic buckle arm 801. The free end of the elastic buckle arm 801 is provided with a protrusion 1301. The mating structure is provided with a corresponding groove that mates with the protrusion 1301. The inner side of the elastic buckle arm 801 is also provided with a ball 1201 for reducing the frictional resistance of the tool holder 401 during installation. The ball 1201 makes rolling contact with the inner wall of the groove.

[0029] By using the push-button buckle structure 301 in conjunction with the elastic reset component 701, the tool holder 401 can be "pressed and installed, pressed and removed". Compared with the traditional screw fixing method, the replacement time is shortened and the equipment maintenance efficiency is improved.

[0030] Furthermore, the elastic reset component 701 includes a spring, one end of which is fixed in the mounting groove of the main body 101, and the other end abuts against the tool holder 401. The ball bearing 1201 on the inner side of the elastic latch arm 801 rolls in contact with the inner wall of the slot, converting traditional sliding friction into rolling friction, reducing frictional resistance, making the tool holder 401 move more smoothly, and avoiding installation problems caused by excessive frictional resistance.

[0031] Furthermore, a guide structure 901 is provided between the tool holder 401 and the main body 101. The guide structure 901 includes a slide rail provided on the main body 101 and a slide groove provided on the tool holder 401. The slide rail and the slide groove are slidably engaged, and the tool holder 401 can move along the extension direction of the slide rail.

[0032] The T-shaped slide rail and the limiting groove design control the lateral displacement error of the blade holder 401 to within 0.1mm, ensuring the positional accuracy of the stripping blade 501 when rotating at high speed and improving the cutting quality of wire stripping.

[0033] Furthermore, the slide rail has a T-shaped cross-section, and the slide groove has a cross-sectional shape that matches the slide rail. The slide rail is provided with a limiting protrusion 1301 at its end, and the inner wall of the slide groove is provided with a limiting groove that cooperates with the limiting protrusion 1301. The limiting groove is used to prevent the tool holder 401 from shifting laterally during movement.

[0034] The T-shaped slide rail on the main body 101 forms a sliding pair with the slide groove of the tool holder 401, allowing the tool holder 401 to move only in a straight line along the extension direction of the slide rail. The limiting protrusion 1301 at the end of the slide rail engages with the limiting groove on the inner wall of the slide groove, restricting the lateral displacement of the tool holder 401 during movement and preventing the tool holder 401 from shifting due to external force vibration. This structural design ensures that the tool holder 401 maintains a precise movement trajectory during installation and disassembly, preventing damage to the snap-fit ​​structure 301 due to lateral force.

[0035] Furthermore, the cutting tool 501 is detachably mounted on the tool holder 401 via a quick-release structure. The quick-release structure includes a mounting hole on the tool holder 401 and a locking portion on the cutting tool 501. The locking portion engages with the mounting hole and is locked by rotation. The locking portion is cylindrical, and its outer surface has an annular groove 1101. A resilient hook is provided on the inner wall of the mounting hole corresponding to the annular groove 1101. One end of the resilient hook has a guide slope, which slides in contact with the outer surface of the locking portion.

[0036] The cutting tool 501 is inserted into the mounting hole of the tool holder 401 through the cylindrical locking part. Rotating the cutting tool 501 aligns the annular groove 1101 on the outer surface of the locking part with the elastic hook on the inner wall of the mounting hole. The guide slope of the elastic hook slides in contact with the outer surface of the locking part. During rotation, the hook is deformed by pressure. When the annular groove 1101 reaches the predetermined position, the hook elastically resets and engages in the groove, thus locking the cutting tool 501. To disassemble, rotate the cutting tool 501 in the opposite direction, and the hook slides out of the groove along the guide slope, allowing the cutting tool 501 to be quickly removed.

[0037] Furthermore, the main body 101 is provided with a safety locking device 601 to prevent the tool holder 401 from accidentally falling off. The safety locking device 601 includes a locking bolt 1001 provided on the main body 101 and a locking hole provided on the tool holder 401. The locking bolt 1001 is inserted into the locking hole by a spring.

[0038] The locking bolt 1001 on the main body 101 maintains a tendency to move towards the tool holder 401 under the action of the spring. After the tool holder 401 is installed in place, the locking bolt 1001 is inserted into the locking hole of the tool holder 401 under the action of the spring force, forming a double locking structure. Even if the snap-fit ​​structure 301 undergoes slight deformation due to accidental force, the locking bolt 1001 can still prevent the tool holder 401 from falling off, ensuring the safety of the equipment in high-speed operation or vibration environments.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
