Description

Technical Field

[0001] This utility model relates to the technical field of cable testing equipment, specifically to a slicing and sample preparation device, which is suitable for cable quality testing in industries such as power and communications. Background Technology

[0002] After cables are manufactured, they need to undergo a series of performance and dimensional tests, such as the thickness of the cable insulation layer, to meet national or industry standards and market demands.

[0003] Typically, cable insulation thickness testing requires first preparing a cross-section of the cable, then using a cable-specific projector to inspect the insulation thickness. Currently, cable cross-section preparation is done manually with a handheld blade, which has the following drawbacks:

[0004] There is a safety hazard: the operator's hands come into direct contact with the blade, which can easily lead to cuts;

[0005] Poor slice quality: Uneven manual force application leads to tilted slices and inconsistent thickness, affecting detection accuracy;

[0006] Low compatibility with irregularly shaped cables: It is inconvenient to fix cables with irregular cross-sections, and cutting is prone to deviation, which also affects the detection accuracy.

[0007] There are also hand-operated cutting and sample preparation machines on the market. By turning the handle, the gears are rotated, which causes the rack to move the blade vertically to cut the sample. Although the operator does not need to directly contact the blade, the vertical downward movement of the blade can cause excessive deformation of the cable insulation layer, and the detection accuracy is not improved. Utility Model Content

[0008] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a slicing sample preparation device. The pressure rod drives the knife holder and blade to slice downward along the slide rod. During the downward pressing of the blade, horizontal cutting is performed simultaneously, which reduces the resistance during the slicing process and also reduces the lateral deformation of the insulation during the pressing process, thereby reducing the slicing sample preparation error and improving the detection accuracy of the insulation layer.

[0009] The purpose of this utility model is achieved as follows:

[0010] A slicing and sample preparation device includes a base, on which a support column and a cutting table are provided. The support column is fixedly mounted on the base, and the cutting table is movably mounted on the base. The support column is connected to a sliding rod and a pressure rod. The sliding rod is inclined. The pressure rod is connected to the support column through a locking sleeve. The locking sleeve is hinged to one end of the pressure rod. A slider is sleeved on the pressure rod. The slider is hinged to a blade holder. The blade holder is sleeved on the sliding rod. The blade holder has a sliding hole corresponding to the sliding rod. A blade is installed at the bottom of the blade holder.

[0011] Preferably, the bottom of the cutting table is provided with a slider nut corresponding to the lead screw, the slider nut passes through the base and is sleeved on the lead screw, and the base is provided with a sliding groove corresponding to the slider nut.

[0012] Preferably, the cutting table is stepped and includes a limiting table and a slicing table. The limiting table is higher than the slicing table, and the limiting table is provided with multiple slots of different diameters.

[0013] Preferably, the cutting table is made of PE material, and the limiting table, slicing table and slider nut are integrally formed.

[0014] Preferably, the upper and lower ends of the slide rod are connected to the support column through sliding sleeve rods, and the horizontal length of the upper sliding sleeve rod is greater than the horizontal length of the lower sliding sleeve rod.

[0015] Preferably, the slide bar is at a 45° angle to the support column.

[0016] Preferably, the sliding sleeve rod and the locking sleeve are both sleeved on the support column and locked with bolts.

[0017] Preferably, the cutting table is driven to move left and right by a lead screw, both ends of the lead screw are fixed to the base by lead screw seats, and one end of the lead screw is fixedly connected to the lead screw handle.

[0018] Preferably, the base is shaped like a gate, and the lead screw and lead screw seat are fixed inside the gate-shaped base.

[0019] The beneficial effects of this utility model are:

[0020] The pressure bar drives the cutter holder and blade to slice downwards along the slide bar. Simultaneous horizontal cutting occurs during the downward pressure of the blade, reducing resistance during slicing and minimizing lateral deformation of the insulation during the downward pressure process. This reduces slicing and sample preparation errors, thereby improving the accuracy of subsequent insulation layer testing.

[0021] The blade remains perpendicular to ensure consistent slice thickness and reduce errors caused by manual operation. The blade holder is compatible with common carbon steel blades on the market, greatly reducing the cost of blade replacement.

[0022] The cutting table is equipped with slots of multiple sizes, which can fix the position of the cable to be cut during the slicing process, making it highly versatile. Attached Figure Description

Detailed Implementation

[0029] See Figure 1-5 This utility model relates to a slicing and sample preparation device, including a base 1, a support column 2, a cutting table 3, a blade holder 4, a slider 5, a pressure rod 6, a sliding rod 7, and a blade 8. The base 1 is provided with the support column 2 and the cutting table 3. The support column 2 is fixedly mounted on the base 1, and the cutting table 3 is movably mounted on the base 1. The support column 2 connects the sliding rod 7 and the pressure rod 6. The sliding rod 7 is inclined and forms a 45° angle with the support column 2. The upper and lower ends of the sliding rod 7 are respectively connected to the support column through sliding sleeve rods 9. 2. The horizontal length of the upper sliding sleeve rod 9 is greater than that of the lower sliding sleeve rod 9, causing the sliding rod to tilt. The pressure rod 6 is connected to the support column 2 through the locking sleeve 10. The sliding sleeve rod 9 and the locking sleeve 10 are both sleeved on the support column 2 and locked with bolts. The locking sleeve 10 is hinged to one end of the pressure rod. A slider 5 is sleeved on the pressure rod 6. The slider 5 is hinged to the tool holder 4. The tool holder 4 is sleeved on the sliding rod 7. The tool holder 4 has a sliding hole corresponding to the sliding rod 7. A blade 8 is installed at the bottom of the tool holder 4.

[0030] The cutting table 3 is driven to move left and right by a lead screw 11. Both ends of the lead screw 11 are fixed to the base 1 by lead screw seats 12. The base 1 is shaped like a gate. The lead screw 11 and lead screw seats 12 are fixed inside the gate-shaped base 1. One end of the lead screw 11 is fixedly connected to the lead screw handle 13. By shaking the lead screw handle 13, the cutting table 3 is driven to move left and right.

[0031] The bottom of the cutting table 3 is provided with a slider nut 3.1 corresponding to the lead screw 11. The slider nut 3.1 passes through the base 1 and is sleeved on the lead screw 11. The base 1 is provided with a sliding groove corresponding to the slider nut 3.1.

[0032] The cutting table 3 is stepped, including a limiting platform 3.2 and a slicing platform 3.3. The limiting platform 3.2 is higher than the slicing platform 3.3. The limiting platform 3.2 is provided with multiple slots 3.4 of different diameters, such as... Figure 3As shown, the limiting stage 3.2 has four slots 3.4 with different diameters, ranging from φ5mm, φ7mm, φ10mm, to φ15mm. To improve slicing accuracy, the lowest point of each slot 3.4 is flush with the slicing stage 3.3. Depending on the cable size, a suitable slot 3.4 is selected to limit and fix the cable. By adjusting the position of the cutting stage 3, the blade 8 is positioned above the slicing stage 3.3 behind the corresponding slot 3.4.

[0033] The cutting table 3 is made of PE material, and the limiting table 3.2, the slicing table 3.3 and the slider nut 3.1 are integrally formed.

[0034] Section preparation method:

[0035] The cable with the core pre-emptively removed is placed in the corresponding slot 3.4. The screw handle 13 is manually adjusted to adjust the position of the cutting table 3. The pressure rod 6 is pulled down, and the pressure rod 6 is pulled down with the hinge point on the locking sleeve 10 as the center. This pulls the slider 5 and the blade holder 4 on it to tilt downward along the slide rod 7. In this way, the blade 8 no longer cuts vertically straight up and down, but cuts horizontally simultaneously during the downward pressing of the blade, reducing the resistance during the cutting process and also reducing the lateral deformation of the cable during the pressing process.
