Description
Technical Field
[0001] This invention relates to the field of cable slicing and sampling technology, and specifically to a linkage-type cable slicing and sampling device. Background Technology
[0002] With the rapid development of my country's power construction and the continuous improvement of the power grid system, the demand for power cables has surged. While production capacity is expanding rapidly, ensuring product performance and quality has become paramount. Among the key aspects of this, rapid and accurate testing of cable samples is crucial for guaranteeing product quality. Efficient, convenient, and high-quality slicing and sampling of the cable's external insulation layer is a necessary prerequisite for conducting relevant tests. According to the relevant sample preparation requirements of GB / T 2951.11-2008, dumbbell-shaped specimens should be used whenever possible. Preparing dumbbell-shaped specimens requires cutting test strips from the cable insulation layer, with a thickness between 0.8 and 2.0 mm. If this is still insufficient, the minimum allowable thickness is 0.6 mm.
[0003] Traditional testing laboratories often rely on hand-held cutters to sample cables, resulting in poor uniformity and consistency of the obtained samples, low sample preparation efficiency, and difficulty in meeting the needs of current cable testing work. As for the cable slicing devices commonly used in the market, they usually occupy a large space, have high manufacturing costs, require an external power source, and have high requirements for the operating environment. Moreover, after each slicing, manual intervention is usually required to manually adjust the position of the cable sample before the next cutting and sampling can be carried out, which reduces the sample preparation efficiency and affects the stability of the finished product quality. Summary of the Invention
[0004] Therefore, in view of the above technical problems, the present invention provides a linkage-type cable slicing sampling device. Through the linkage and cooperation of each module, the cable sample can be clamped once and then continuously slicing and sampling can be completed. There is no need for manual intervention to adjust the sample position during the sample preparation process, which ensures the stability of the slice quality. In addition, the thickness of the obtained slices can be adjusted according to actual needs to meet the requirements of different tests.
[0005] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution: a linkage-type cable slicing and sampling device, comprising a frame, a drive module, a cutting module, a clamping module, a limit plate, a platform lifting slider, a platform lifting guide rail, a locking module, a feed module, and mounting feet. The frame, serving as the structural framework of the entire device, is fixedly connected to the mounting feet to secure and support other modules. The drive module runs through the entire device from top to bottom, providing necessary power to the cutting module, locking module, and feed module. The cutting module, located at the top of the frame, is used to cut the cable sample. The clamping module, located in front of the cutting module, is connected to the frame via a platform lifting slider and a platform lifting guide rail, allowing it to move vertically relative to the frame along the platform lifting guide rail. Limiting plates are installed at the front and rear of the clamping module to restrict the cable sample's position within the clamping module. The locking module, located in the middle layer of the frame below the cutting module, locks the clamping module's position in space, thus assisting the cutting module in completing the cutting operation. The feed module, located at the bottom of the frame, supports and pushes the clamping module upwards along the platform lifting guide rail. Through its coordinated operation with the locking and cutting modules, it performs continuous multiple slicing and sampling of the cable sample. Furthermore, the slice thickness can be adjusted according to actual needs to meet different testing requirements.

A cam is installed in the middle section of the camshaft, which can rotate synchronously with the camshaft, thereby driving the push rod to move horizontally back and forth. The push rod is a frame structure with guide strips installed at its top and bottom. The guide strips cooperate with the grooves on the middle beam of the frame. In addition, the push rod is also hinged to both the left and right connecting rods through a pin. The other end of the left connecting rod is hinged to the left fork arm, and similarly, the other end of the right connecting rod is also hinged to the right fork arm. The middle part of the left fork arm is hinged to both the right fork arm and the frame through a fork arm pivot. The left and right forks can rotate synchronously around the fork arm pivot. The left fork arm has a sliding groove at its front end, which cooperates with the middle section of the pressure block connecting shaft, allowing the pressure block connecting shaft to move along the sliding groove. The connection method of the right fork arm is similar. The pressure block connecting shaft is set into two groups, left and right. The upper and lower ends of each group of pressure block connecting shafts are hinged to the corresponding pressure blocks, which can synchronously drive the upper and lower groups of pressure blocks to move horizontally.

A small synchronous pulley is fixedly mounted on the middle section of the grooved wheel shaft, and both ends of the grooved wheel shaft are fixedly connected to the frame via grooved wheel shaft mounting seats. The small synchronous pulley is connected to a large synchronous pulley via a lower synchronous belt, and the large synchronous pulley is fixedly mounted on the middle section of the large synchronous pulley shaft. Feed teeth are also fixedly mounted on the middle section of the large synchronous pulley shaft. The feed gear meshes with the feed rack below. As the synchronous large pulley shaft rotates, the feed gear drives the feed rack to move horizontally forward. The feed rack engages with the feed rack guide rail through its own wedge structure, and its front end is fixedly connected to the feed table, which can push the feed table to move back and forth along the rack guide rail. Wedge block limit seats are fixedly installed on both sides of the feed table, and there are wedge block guide rods between the wedge block limit seats. Several sets of feed wedge blocks with different inclinations are set on the feed table. As the feed table moves forward as a whole, the feed wedge blocks support and push the rollers and the clamping table body and other components on them to move vertically upward.
[0016] The foremost heights of the several sets of feed wedges are all the same, and the height of their tail ends gradually increases with the slope. The several sets of wedges are fixed together by bolts. A wedge adjustment plate is fixedly installed on the side.

Several sets of feed wedge blocks 916 with different inclinations are provided on the feed table 915. While the feed wedge blocks 916 move forward with the feed table 915 as a whole, they support and push the roller 409 and the clamping table body 408 and other components to move vertically upward.
[0034] The foremost heights of the several sets of feed wedges 916 are all the same, and the height of their tail ends gradually increases with different inclinations. The several sets of wedges 916 are fixed together by bolts. A wedge adjustment plate 918 is fixedly installed on the side. After releasing the other parts from limiting the wedges 916, pulling the wedge adjustment plate 918 allows the feed wedges 916 to move laterally along the wedge guide rod 917. The rear of the feed table 915 is provided with multiple sets of mounting holes, each containing a positioning pin 920 and a positioning pin spring 922. The positioning pin 920 has a ball head at its front end and is fixedly connected to a connecting rod 921 at its tail end. The other end of the connecting rod 921 is connected to the mounting plate 921 of the feed table 915.

One end is connected to the corresponding lifting ring 926 installed on the bottom beam of the frame 1; one end of the synchronous large pulley shaft 911 is fixedly connected to the frame 1 through the synchronous large pulley shaft mounting seat 913, and the other end is fixedly connected to the frame 1 through the ratchet mounting seat 931; the ratchet 927 is fixedly installed on the synchronous large pulley shaft 911 and located inside the ratchet mounting seat 931, and a pawl 928 is provided below the ratchet 927 to cooperate with it; the pawl 928 has mounting shafts on both sides and is installed in the corresponding mounting holes on the ratchet mounting seat 931, and the pawl 928 can swing within a certain range; a pawl compression spring 929 is also provided inside the ratchet mounting seat 931, one end of which abuts against the ratchet mounting seat 931 and the other end abuts against the pawl. On 928, a pawl 928 is used to ensure that it always maintains contact with the ratchet 927; the pawl lever 930 is located on the outer side of the ratchet mounting base 931 and can rotate the pawl 928 to disengage it from the ratchet 927; multiple sets of wedge block guide pins 932 are fixedly installed at the bottom front end of the feed wedge block 916, and each feed wedge block 916 is equipped with one wedge block guide pin 932. When the feed wedge block 916 moves forward with the worktable, each wedge block guide pin 932 slides into the corresponding groove on the wedge block guide groove plate 933; the wedge block guide groove plate 933 is fixedly connected to the frame 1 and is located in front of the feed worktable 915, and its upper surface is provided with several sets of grooves;The feed table sliders 934 are configured in multiple sets, located below and fixedly connected to the feed table 915, to support the feed table 915 in horizontal back-and-forth movement along the feed table guide rail 935.
[0035] The working principle of this invention is: After cutting a section of cable sample, the operator can rotate the fixing knob 406 to drive the lead screw shaft 403 to rotate, increasing the distance between the right fixing block 401 and the left fixing block 402, placing the cable sample between the right fixing block 401 and the left fixing block 402, and then rotating the fixing knob 406 in the opposite direction to clamp it. According to the initial position of the cable sample clamping, the operator turns the adjustment knob 312 to adjust the working height of the tool mounting bracket 309 and the slicing tool 310 to adapt to the initial position of the cable sample. Then, by turning the handwheel 201, the power spindle 203 and the power spindle synchronous pulley 205, crank 301 and other components mounted on it can be driven to rotate, thereby driving the connecting rod 303 to make planar motion, driving the feed drive gear 304 at the end of the connecting rod 303 to roll forward relative to the fixed rack 306, thereby driving the feed rack 307 to move along the feed rack guide rail 317, and finally pushing the slicing tool 310 mounted at the front end of the feed rack 307 to move back and forth, realizing the cyclical motion of feed cutting and retraction reset of the cable sample.
[0036] Meanwhile, the power spindle synchronous pulley 205 transmits power to the locking module synchronous pulley 207 via the upper synchronous belt 206, thereby driving the camshaft 801 and the cam 802 mounted on the shaft to rotate together. When the feed module 3 is about to contact the cable sample and begin cutting, the cam 802 rotates to its near-end section and contacts the push rod 804, keeping the push rod 804 in its original position. The pressure block 812 presses against the clamping table body 408 under the action of the spring inside the pressure block guide sleeve 814, and the clamping module 4 is in a locked state to ensure its stability during the slicing process. When the feed module 3 completes the cutting and retracts to the point of disengagement from the cable sample, the cam 802 rotates to the push stroke section, which gradually pushes the push rod 804 forward, thereby driving the left connecting rod 806 and the right connecting rod. When 807 moves in a planar motion, it causes the left fork arm 808 and the right fork arm 809 to rotate synchronously around the fork arm pivot 810 in opposite directions, forcing the pressure blocks 812 on the left and right sides of the worktable body 408 to gradually disengage from the worktable body 408, and the clamping module 4 is unlocked. When the cam 802 continues to rotate to the far end, the push rod 804 remains stationary at the maximum push position, and the other components also remain stationary. The clamping module 4 remains unlocked until the cam 802 rotates to the return end. The push rod 804 and the connected components such as the left connecting rod 806, the right connecting rod 807, the left fork arm 808, the right fork arm 809, and the pressure block 812 gradually reset under the action of the spring inside the pressure block guide sleeve 814, returning to the initial position, and the clamping module 4 re-enters the locked state.
[0037] Similarly, the locking module synchronous pulley 207 also transmits power to the feed module synchronous pulley 209 via the intermediate synchronous belt 208, thereby driving the dial shaft 901 and the dial 902 mounted on the shaft to rotate together. When the cam 802 rotates to the far end and contacts the push rod 804, the fixing pin on the dial 902 enters the groove of the grooved wheel 904, thereby pushing the grooved wheel 904 to rotate a certain angle. The grooved wheel 904 drives the grooved wheel shaft 906 and the small synchronous pulley 905, which are coaxial with it, to rotate synchronously through the same angle through the overrunning clutch 907. At the same time, the small synchronous pulley 905 drives the large synchronous pulley 910 to rotate through a corresponding small angle through the lower synchronous belt 909. The large synchronous pulley shaft 911 and the feed gear 912, which are coaxial with the large synchronous pulley 910, also rotate through the same angle, thereby driving the feed rack 914 along the feed rack guide rail 93. 6. Move forward a fixed distance, eventually pushing the feed table 915 and the feed wedge block 916 mounted on it forward by the same distance. The feed wedge block 916 pushes the roller 409 and the clamping table body 408 and other components to move upward a fixed distance together. Thus, after the cutting of the feed module 3 is completed, the clamping module 4 is driven to complete one feed movement. When the feed table 915 moves forward to the limit position, simply move the pawl lever 930 to press the pawl 928 to rotate and disengage it from the ratchet 927. Then, under the action of the feed module return spring 925 installed at the bottom of the frame 1, the feed table 915 and the feed rack 914 and other related components are pulled to complete the reset. During this process, although the synchronous large pulley shaft 911 and the grooved wheel shaft 906 reverse, under the action of the overrunning clutch 907, the grooved wheel 904 continues to maintain its original state and is not affected by it.
[0038] When the thickness of the slice needs to be adjusted, with the feed table 915 in its initial position, the positioning pin lever 924 can be moved to move the positioning pin 920 and connecting rod 921 backward, compressing the positioning pin spring 922. The ball head at the front end of the positioning pin 920 will exit the blind hole on the feed wedge block 916 that matches it. Then, the wedge block adjusting lever 918 can be pulled, and multiple sets of wedge blocks 916 will slide laterally along the wedge block guide rod 917 until the wedge block 916 with the required slope contacts the roller 409. Then, the positioning pin lever 924 can be released, and the positioning pin 920 will pop out, and the wedge block 916 will... Guided by a tapered blind hole at the tail end, the wedge block 916 is inserted to lock its movement. In addition, the wedge block guide pin 932 installed at the bottom of the front end of the wedge block 916 gradually slides into the groove on the wedge block guide plate 933 as the feed table 915 begins to move forward. This also helps to position and lock the wedge block 916. Even if the positioning pin plate 924 is accidentally moved, the wedge block 916 will not fail to lock. This further ensures that the position of all wedge blocks 916 relative to the feed table 915 remains unchanged during the forward feeding process.
