[0002] Non-destructive testing (NDT) equipment is required when inspecting copper. To ensure the accuracy of the equipment, the sensitivity of radiographic testing to the thickness of the copper block needs to be tested using stepped copper test blocks. The stepped test blocks are formed with different thicknesses, and the sensitivity of the tests is compared.

[0003] Currently, copper contrast stepped test blocks are mainly made by hand cutting and polishing, which is slow and the stepped shape is difficult to cut. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a cutting device that facilitates the cutting of stepped copper comparison test blocks.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Please see Figures 1-3 This application discloses a cutting device for processing copper comparison test blocks, comprising a mounting base 1, a fixed frame 11 fixedly mounted on the mounting base 1, the fixed frame 11 including two parallel support rods, a cutting assembly 2 mounted on the mounting base 1, the cutting assembly 2 including a saw blade 21 and a drive motor, the saw blade 21 being rotatably mounted on the upper middle part of the fixed frame 11, the output end of the drive motor driving the saw blade 21, a lifting feed surface 31 being vertically mounted on the mounting base 1, the fixed frame 11 and the saw blade 21 passing through the lifting feed surface 31, and a transverse feed surface being slidably mounted on the lifting feed surface 31. A longitudinal feed surface 33 is slidably mounted on a transverse feed surface 32. A tooling surface 34 is rotatably mounted on a longitudinal feed surface 33. The upper end of the tooling surface 34 is flush with the upper end of the lifting feed surface 31. A right-angle clamping plate 41 is fixedly mounted on the upper end of the tooling surface 34. A positioning frame 42 is fixedly mounted on the tooling surface 34. A positioning drive rod 43 is fixedly mounted on the upper end of the positioning frame 42. The output end of the positioning drive rod 43 faces the upper surface of the tooling surface 34. The lifting feed surface 31, the transverse feed surface 32, the longitudinal feed surface 33, and the tooling surface 34 are all connected to a drive component 35 that drives their feed.

[0038] Specifically, the three-degree-of-freedom feeding part is formed by the lifting feed surface 31, the transverse feed surface 32 and the longitudinal feed surface 33, the right-angle clamping plate 41 and the tooling surface 34 form the positioning part, and the positioning frame 42 and the positioning drive rod 43 form the clamping part, so that the copper comparison test block is positioned and clamped at the upper end of the mounting base 1 and moves with the feeding part, and is cut by the cutting assembly 2.

[0039] In this way, the copper comparison test block is clamped on the tooling surface 34 by setting the right-angle clamping plate 41 and the drive rod 43, and the copper comparison test block is fed and moved by the lifting feed surface 31, the transverse feed surface 32 and the longitudinal feed surface 33, and the cutting component 2 is used to complete the cutting, thereby improving the automation level of the stepped test block cutting and improving the production efficiency of the stepped test block.

[0040] In some feasible ways, the mounting base 1 is a rectangular box shape, the drive motor is installed in the mounting base 1, the saw blade 21 is installed on the fixing frame 11, the drive motor is connected to the saw blade 21 through a chain or belt mechanism, the drive motor is set at the bottom, and the saw blade 21 is supported by the fixing frame 11, which reduces the inconvenience caused by the installation position of the drive motor to the copper block cutting.

[0041] The lifting feed surface 31 is Z-shaped, the saw blade 21 is installed on the higher side of the lifting feed surface 31, and the transverse feed surface 32 is installed on the lower side of the lifting feed surface 31 so that the upper end of the tooling surface 34 can be flush with the upper end of the lifting feed surface 31. Both the transverse feed surface 32 and the longitudinal feed surface 33 are rectangular plates. The driving component 35 can be a ball screw or a linear drive mechanism such as a cylinder or hydraulic cylinder. The tooling surface 34 is disc-shaped, and a gear ring is provided on the outer side of the tooling surface 34. The driving component 35 of the tooling surface 34 is a drive motor and a drive gear.

[0042] The right-angle clamping plate 41 is a right-angle structure formed by two rectangular plates, the positioning frame 42 is an L-shaped frame, and the positioning drive rod 43 is a cylinder. When the copper block is installed in the position of the right-angle clamping plate 41, the positioning drive rod 43 presses down to clamp the copper block.

[0043] The following section will provide further details based on specific usage scenarios.

[0044] In use, the corner of the copper block that does not need to be processed is installed in the right-angle clamping plate 41 and locked by pressing down the positioning drive rod 43. The transverse feed surface 32 and the longitudinal feed surface 33 cooperate to feed. After the transverse feed surface 32 is fed into place, the lifting feed surface 31 moves, so that the copper block moves up or down along the tangent of the saw blade 21 to form a straight cut. When it is necessary to cut the other side, the position is changed by rotating the tooling surface 34.

[0045] As one specific embodiment of the cutting device for processing copper comparison test blocks provided in the application, please refer to Figure 3 The two outer sides of the right-angle clamping plate 41 are threadedly connected with clamping rods 441, and clamping plates 442 are rotatably mounted on the end face of the clamping rods 441.

[0046] Overall, the copper block is clamped at both ends by clamping rod 441 and clamping plate 442, which further improves the stability of the copper block during processing.

[0047] In some feasible embodiments, the outer side of the right-angle clamping plate 41 is provided with a rectangular block with a threaded hole, the clamping rod 441 is a threaded rod that is threadedly connected to the rectangular block, the clamping plate 442 is a rectangular plate, and a rotating wheel for rotating the clamping rod 441 is provided at the end of the clamping rod 441 away from the clamping plate 442.

[0048] As another specific embodiment of the cutting device for processing copper comparison test blocks provided in the application, a positioning pin 341 is slidably installed in the longitudinal feed surface 33, and at least two positioning holes 342 are provided on the side of the tooling surface 34. The positioning pin 341 is connected to a positioning drive 343.

[0049] Depending on the specific application scenario, the copper block is fed linearly along the rotating plane of the saw blade 21 during processing. By setting the positioning pin 341, the tooling surface 34 is positioned, reducing the possibility of circumferential oscillation of the tooling surface 34 during processing.

[0050] Furthermore, a normally open switch 351 is provided at the end of the positioning pin 341 away from the positioning hole 342, and the normally open switch 351 is connected in series in the power supply circuit of the driving component 35 of the tooling surface 34.

[0051] It should be understood that by setting the normally open switch 351 to control the drive component 35 of the tooling surface 34, the situation where the drive component 35 of the tooling surface 34 is accidentally activated when the positioning pin 341 is in the inserted state or not fully withdrawn is reduced.

[0052] As one specific embodiment of the cutting device for processing copper comparison test blocks provided in the application, please refer to Figure 1 The driving components 35 for the lifting feed surface 31, the transverse feed surface 32, and the longitudinal feed surface 33 are ball screw mechanisms.

[0053] It should be understood that the feed accuracy is improved by setting up a ball screw mechanism.

[0054] In some feasible embodiments, triangular rails are provided on both sides of the ball screw mechanism to facilitate support for the transverse feed surface 32 and the longitudinal feed surface 33.

[0055] Furthermore, telescopic rods are installed at the top corners of the lifting feed surface 31.

[0056] It should be understood that by setting up a telescopic rod, the two sides of the telescopic rod are attached to each other, so that the telescopic rod remains in a vertical state, thereby keeping the upper lifting feed surface 31 in a horizontal state. This forms a support at the top corner of the lifting feed surface 31, reducing the possibility of the top corner of the lifting feed surface 31 bending downward.

[0057] Furthermore, a normally closed switch 352 is installed at the upper end of the lifting feed surface 31 near the fixed frame 11. The normally closed switch 352 is connected in series in the power supply circuit of the drive unit 35 of the transverse feed surface 32.

[0058] It should be understood that by setting the normally closed switch 352 to control the drive component 35 of the transverse feed surface 32, the possibility of the transverse feed surface 32 overfeeding and hitting the fixed frame 11 is reduced.

[0059] Further, please refer to Figure 2 The lead screw of the rolling lead screw mechanism is fixedly connected to a manual rotating wheel 353.

[0060] It should be understood that by setting the manual rotary wheel 353, it is convenient to control the manual retraction after the normal closed switch 352 stops the feed of the transverse feed surface 32, and it is also convenient to manually feed during machining.

[0061] In some feasible methods, for ease of operation, the manual rotating wheel 353 is set on the same side of the mounting base 1. The manual rotating wheel 353 is connected to the connecting rod, and the connecting rod is connected to the screw of the corresponding ball screw mechanism through a bevel gear set. When the drive motor of the ball screw mechanism is a motor with a self-locking function, a clutch should be set at the connection position between the drive motor and the screw.

[0062] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
