[0040] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0041] Refer to Figure 1-7 , the present invention discloses a grooving and cutting device for grooving and cutting a test block 100, which includes a machine table 1 and a cutting mechanism 2 and an adjustment mechanism installed on the machine table 1. The adjustment mechanism includes an adjustment table 3, an adjustment component and a limit component.

[0042] The adjustment table 3 is provided with a cutting hole 31, and the cutting tool 21 of the cutting mechanism 2 passes through the cutting hole 31 so that the cutting tool 31 protrudes from the upper surface of the adjustment table 3.

[0043] The adjustment component includes an adjustment rod 4 fixedly installed on the machine table 1. The adjustment table 3 is sleeved outside the adjustment rod 4 and can move along the adjustment rod 4 to adjust the inclination of the adjustment table 3 relative to the cutting tool 21; the limit component is arranged on the upper surface of the adjustment table 3 to limit the cutting position of the cutting tool 31 on the test block 100.

[0044] The grooving and cutting device of the present invention adopts the method of moving the adjusting table along the adjusting rod to adjust the height on one side of the adjusting table, so as to form a preset angle between the adjusting table and the cutting tool. The test block is placed on the upper surface of the adjusting table, and the cutting tool protrudes from the upper surface of the adjusting table through the cutting hole to cut the test block, thereby forming a groove with the required depth and angle on the test block. And under the limiting action of the limiting component, the position of the groove on the test block is accurately controlled. The structure of the present invention is simple and small in size, can accurately control the position of the groove on the test block and obtain grooves with different depths and angles, and has high cutting accuracy.

[0045] Specifically, as Figure 1-3 shown, the adjusting rod 4 is vertically connected to the machine table 1, and the cutting tool 21 and the machine table 1 are perpendicular to each other, ensuring the accuracy of the angle adjustment between the adjusting table and the cutting tool, thereby ensuring high cutting accuracy.

[0046] To ensure the stability of the adjusting table, preferably, the number of the adjusting rods 4 is four, which are evenly distributed around the machine table 1. The adjusting table 3 is respectively sleeved outside the four adjusting rods 4. By adjusting the position of the adjusting table on two of the adjusting rods, the inclination of the adjusting table relative to the cutting tool can be adjusted.

[0047] Preferably, as Figure 1-4 shown in FIGS. 6 and 7, the adjusting component further includes a locking member 5, the locking member 5 is movably connected to the adjusting rod 4, and the adjusting table 3 is placed on the locking member 5. Preferably, the locking member 5 is a nut, the adjusting rod 4 is provided with an external thread, and the locking member 5 is sleeved on the adjusting rod 4 and is threadedly connected to the adjusting rod 4. Rotating the locking member can adjust the position of the locking member on the adjusting rod. The adjusting table is sleeved outside the adjusting rod and is erected on the locking member. When the locking member moves, the adjusting table is driven. Adjusting the position of the locking member on the adjusting rod, that is, adjusting the position of the adjusting table on the adjusting rod. Specifically, the position of the locking member can be adjusted towards the top or bottom of the adjusting rod.

[0048] More preferably, at least two locking members 5 are provided on each adjusting rod 4, and the adjusting table 3 is arranged between the two locking members 5. After adjusting the position of the adjusting table on the adjusting rod, rotate the locking member above the adjusting table to make it move towards the adjusting table direction, so as to clamp the adjusting table between the two locking members, thereby fixing the adjusting table on the corresponding adjusting rod, and avoiding the displacement or jumping of the adjusting table during work, which affects the cutting accuracy.

[0049] It should be noted that, in order to facilitate the adjustment of the inclination of the adjustment table relative to the cutting tool and ensure the accuracy of the adjustment, the adjustment table 3 is square in shape, and the four adjustment rods 4 are respectively arranged at the four corners of the adjustment table 3. The plane where the cutting tool 21 is located is perpendicular to two opposite sides of the adjustment table 3, and the other two opposite sides of the adjustment table 3 are parallel to each other. When adjusting the included angle between the cutting tool and the adjustment table, it is only necessary to adjust the position of one side of the adjustment table parallel to the cutting tool and the two nearest adjustment rods, that is, to adjust the position of the locking members on the two adjustment rods.

[0050] Preferably, in order to synchronously adjust the position of the adjustment table on the two adjustment rods, a scale (not shown in the figure) is provided on the adjustment rod 4 to ensure that the distances between the adjustment table and the machine table on the two adjustment rods are the same, thereby ensuring the cutting accuracy.

[0051] Preferably, as Figure 1-4 shown in FIGS. 6 and 7, the limiting assembly includes a limiting member 6, and the limiting member 6 is movably connected to the adjustment table 3 to adjust the distance between the limiting member 6 and the cutting tool 21. Specifically, the limiting member 6 is arranged between one side of the adjustment table 3 parallel to the cutting tool 21 and the cutting tool 21. During operation, one end face of the test block abuts against the limiting member, and the test block is pushed towards the cutting tool. When pushing the test block, the test block always abuts against the limiting member, ensuring the accuracy of the grooving position and also ensuring the cutting quality of the grooving. The limiting member is movably connected to the adjustment table, that is, the position of the limiting member on the adjustment table can be adjusted, and the distance between the limiting member and the cutting tool can be adjusted to meet the requirements of different grooving positions.

[0052] More preferably, as Figure 4 shown in FIGS. 8 and 7 9, a plurality of positioning holes 32 are provided on the adjustment table 3; the limiting assembly further includes a positioning member 7, and the limiting member 6 is correspondingly arranged with different positioning holes 32 through the positioning member 7.

[0053] The positioning holes are arranged in a direction perpendicular to one side of the adjustment table parallel to the cutting tool. The setting of the positioning holes ensures that the limiting member is always parallel to this side of the adjustment table and can accurately position the limiting member. The positioning member can be a positioning rod, and the positioning member passes through the limiting member and the positioning hole to position the limiting member on the adjustment table. Specifically, the positioning member is a screw rod, and the limiting assembly includes a nut. The positioning member is threadedly connected to the nut to fix the positioning member on the adjustment table to prevent the limiting member from shifting during operation and affecting the cutting accuracy. It should be noted that in addition to the nut, other components can also be used to fix the positioning member, as long as the positioning member can be fixed on the positioning hole and the limiting member and does not come off.

[0054] Preferably, the positioning hole 32 is a threaded hole. The positioning member 7 is threadedly connected to the adjustment table 3 through the positioning hole 32. By rotating the positioning member, the limiting member can be fixed on the adjustment table. The structure is simple, the operation is convenient, and the cost is low.

[0055] Further, in order to accurately adjust the inclination of the adjustment table relative to the cutting tool, as Figure 3-7 shown, the present invention further includes a protractor mechanism. The protractor mechanism includes a protractor 8 and a protractor lifting and lowering assembly. The protractor 8 is mounted on the machine table 1 through the protractor lifting and lowering assembly. The protractor 8 is used to measure the inclination angle of the adjustment table 3.

[0056] By setting the protractor mechanism in the present invention, the inclination angle of the adjustment table can be obtained in real time, ensuring accurate adjustment angle and high cutting accuracy. The protractor lifting and lowering assembly can adjust the position of the protractor in real time, so that the protractor can move with the adjustment table to realize angle measurement.

[0057] Preferably, as Figure 1-5 shown in FIGS. 6 and 7, the protractor lifting and lowering assembly includes a support rod 9 and a lifting rod 10. The support rod 9 is erected on the adjustment rod 4. The protractor 8 is arranged on the lifting rod 10. The support rod 9 and the lifting rod 10 are movably connected so that the center point 81 of the protractor 8 coincides with the adjustment table 3. Specifically, the lifting rod 10 and the protractor 8 are mounted on the top of the adjustment rod 4 through the support rod 9. The structure is simple and space-saving. The lifting rod is inserted through the support rod. The protractor is arranged at the bottom end of the lifting rod. The lifting rod can move up and down, driving the protractor to move up and down, ensuring that the center point of the protractor coincides with the adjustment table to measure the inclination angle of the adjustment table.

[0058] More preferably, as Figure 3-4 shown in FIGS. 6 and 7, a notch 33 is provided on the adjustment table 3. The protractor 8 is inserted through the notch 33. The setting of the notch saves the installation space of the protractor, makes the device small in volume, small in occupied space, portable, and compact in structure, ensuring that the center point of the protractor coincides with the adjustment table and ensuring that the inclination angle of the adjustment table can be obtained in real time when adjusting the adjustment table.

[0059] It should be noted that the support rod needs to be arranged on two adjustment rods corresponding to the side of the adjustment table that needs to be adjusted in height, that is, it needs to be arranged on two adjacent adjustment rods. The position of the adjustment table on these two adjustment rods needs to be adjusted to obtain the required preset included angle between the adjustment table and the cutting tool.

[0060] Preferably, as Figure 1-3As shown in the figure, adjusting feet 11 for adjusting the stability of the machine table 1 are provided at the bottom of the machine table 1. The machine table 1 is square in shape, and the number of adjusting feet 11 is four, which are respectively arranged at the four corners of the bottom of the machine table 1. By adjusting the height of the adjusting feet, the height of the four corners of the machine table can be adjusted, so as to adapt to uneven ground, ensure the machine table is stable and does not shake, and ensure the normal and smooth operation of the device.

[0061] Preferably, the cutting mechanism 2 is fixedly installed on the machine table 1 through a fixing component, ensuring that the cutting knife is always perpendicular to the machine table during the whole working process, that is, ensuring that the cutting mechanism does not move during the whole working process, so as to ensure the cutting accuracy.

[0062] Preferably, as Figure 8 shown in the figure, the cutting device further includes a feeding component, which is detachably connected to the adjusting table 3, and the feeding component is used to automatically cut the test block 100 on the adjusting table 3.

When in use, the mounting plate 131 is clamped to the adjusting table 3, the height position of the feeding driving member 133 is adjusted through the lifting adjustment member 132, so that the pressing part of the pushing block 134 fits with the upper end face of the test block 100, and the pushing part of the pushing block 134 is away from one side of the feeding driving member 133 and fits with the side face of the test block 100, and then the test block 100 is pushed by the feeding driving member 133 for cutting. This feeding device is used for automatically feeding the test block 100 with regular shape. If the test block 100 is irregular in shape, the mounting plate 131 can be removed and the feeding can be carried out manually.

[0064] Preferably, a clamping block is provided on the mounting plate 131, and a clamping groove for clamping with the clamping block is provided on the adjusting table 3; a telescopic support rod 135 is hinged to the lower end of the mounting plate 131, and the support rod 135 is used for auxiliary support of the mounting plate 131.

The positioning frame 14 is used to project a cutting light ray on the adjustment table 3 that is flush with the cutting knife. When manually feeding materials, the staff can feed materials according to the cutting light ray to assist cutting.

[0071] More preferably, the distance measuring sensors 153 are laser sensors or ultrasonic sensors.

[0072] Accordingly, see Figure 11 The present invention also discloses a cutting method of the above-mentioned slotting cutting device, comprising the following steps:

According to the position of the slot required on the test block, the position of the limit assembly on the adjustment table is set, and it is achieved by limiting the distance between the limit assembly and the cutting knife. Specifically, the limit piece is placed on the corresponding positioning hole on the adjustment, and the positioning piece is inserted through the limit piece and the positioning hole to fix the limit piece on the adjustment table.

[0074] S102, adjusting the position of one side of the adjustment platform on the adjustment rod so that a preset angle is formed between the adjustment platform and the cutting knife. Specifically, the locking piece on the adjustment rod is rotated to adjust the position of one side of the adjustment platform on the adjustment rod so that a preset angle is formed between the adjustment platform and the cutting knife to obtain the angle of the slot on the test block. The one side of the adjustment platform is the side where the adjustment platform and the cutting knife are parallel to each other.

[0075] It should be noted that step S101 and step S102 may be performed simultaneously, or step S101 may be performed first and then step S102, or step S102 may be performed first and then step S101.

[0076] S103, place the test block on the adjustment table and place it on one side of the cutting knife, and at the same time, one end of the test block is in contact with the limit assembly. Before the working of the present invention, place the test block to be slotted on the upper surface of the adjustment table, and the cutting knife is perpendicular to the side of the test block, such as Figure 7 shown.

[0077] S104, turn on the power to rotate the cutting knife, push the test block along the limit assembly to the other side of the cutting knife, so that the cutting knife cuts on the test block to form a slot. The present invention can use a foot switch to facilitate the operation of the worker's control device. In the process of pushing the test block, the test block always abuts against the limit assembly, i.e., the limit piece, to ensure the cutting quality of the slot.
