Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a laser-assisted micro-vibration cutting device. Background Technology

[0002] Laser-assisted micro-vibration cutting device is a processing equipment that combines laser heating and micro-vibration cutting technologies. It is mainly used to improve the cutting accuracy and efficiency of difficult-to-machine materials. Laser heating softens the material locally, reducing cutting forces, while micro-vibration cutting technology further reduces cutting forces and cutting temperatures, thereby improving machining quality and surface finish.

[0003] Existing cutting devices typically rely solely on the mechanical force of the cutting tool for cutting. For hard and brittle materials or difficult-to-machine materials such as high-temperature alloys, the cutting force is large and the cutting temperature is high, resulting in low cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a laser-assisted micro-vibration cutting device, which facilitates laser-assisted micro-vibration cutting of workpieces, thereby solving the problem that it is inconvenient to perform laser-assisted micro-vibration cutting of workpieces in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser-assisted micro-vibration cutting device includes a base, a laser head fixedly connected to the upper end of the base, a vertical rod fixedly connected to the upper end of the base, a horizontal rod rotatably connected to the side wall of the vertical rod, a plate fixedly connected to the end of the horizontal rod, a reflecting mirror fixedly connected to the side wall of the plate, a bevel tooth and a main bevel tooth rotatably connected inside the vertical rod, the bevel tooth and the main bevel tooth meshing, and the side wall of the bevel tooth fixedly connected to the end of the horizontal rod; a housing, the housing fixedly disposed on the upper end of the base, a rubber pad fixedly connected between the lower end of the housing and the upper end of the base, two movable plates slidably connected inside the housing, a piezoelectric rod fixedly connected between the inner walls of the two movable plates, an elastic element fixedly connected to the side wall of the movable plate, an impact plate fixedly connected between the side walls of the two elastic elements, and a mounting base fixedly connected to the side wall of the housing.

[0007] Preferably, the upper end of the vertical rod is rotatably connected to a rod body, the lower end of the rod body is fixedly connected to the upper end of the main bevel tooth, the upper end of the rod body is provided with a groove, and a protrusion is slidably connected inside the groove.

[0008] Preferably, a spring is fixedly connected to the lower end of the protrusion and the bottom of the groove, and a circular plate is fixedly connected to the upper end of the protrusion.

[0009] Preferably, two positioning rods are fixedly connected to the lower end of the circular plate, and multiple positioning grooves are provided at the upper end of the vertical rod, with the positioning rods slidably connected to the positioning grooves.

[0010] Preferably, two slots are provided at both the upper and lower ends of the housing, the movable plate is slidably connected to the slots, and a spring is fixedly connected between the side wall of the movable plate and the inner wall of the housing.

[0011] Preferably, piezoelectric actuators are fixedly connected to both sides of the housing, and the connecting end of the piezoelectric actuator is electrically connected to the connecting end of the piezoelectric rod.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. A piezoelectric actuator applies voltage to a piezoelectric rod, causing it to stretch and contract laterally. The deformed piezoelectric rod pushes two movable plates to slide. As the two movable plates slide, they pull two elastic elements, causing the impact plate to slide longitudinally and contact the top of the housing. This generates micro-vibration in the housing, which is transmitted to the mounting base, causing the tool to vibrate. This micro-vibration cuts the workpiece, and the laser irradiation further assists the tool in cutting the workpiece. The synergistic effect of laser heating and micro-vibration cutting helps reduce cutting heat and cutting force, preventing thermal and mechanical deformation of the workpiece, thereby improving machining accuracy and surface quality.

[0014] 2. By sliding the protrusion inside the groove and cooperating with the positioning rod and the positioning slot, the rod body is precisely positioned. This design ensures that the angle of the reflector remains stable after adjustment and will not be easily changed by external factors. At the same time, the illumination angle of the reflector can be flexibly adjusted according to actual processing needs to adapt to different workpieces and processing conditions.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6A laser-assisted micro-vibration cutting device includes a base 001, a laser head 102 fixedly connected to the upper end of the base 001, a vertical rod 103 fixedly connected to the upper end of the base 001, a horizontal rod 104 rotatably connected to the side wall of the vertical rod 103, a plate 105 fixedly connected to the end of the horizontal rod 104, a reflecting mirror 106 fixedly connected to the side wall of the plate 105, a bevel tooth 107 and a main bevel tooth 108 rotatably connected inside the vertical rod 103, the bevel tooth 107 and the main bevel tooth 108 meshing, and the side wall of the bevel tooth 107 fixedly connected to the end of the horizontal rod 104; and a housing 002 fixedly mounted on the base 001. At the upper end, a rubber pad 101 is fixedly connected between the lower end of the housing 002 and the upper end of the base 001. Two movable plates 203 are slidably connected inside the housing 002. A piezoelectric rod 204 is fixedly connected between the inner walls of the two movable plates 203. An elastic element 205 is fixedly connected to the side wall of the movable plate 203. An impact plate 206 is fixedly connected between the side walls of the two elastic elements 205. A mounting base 207 is fixedly connected to the side wall of the housing 002. The laser head 102 is electrically connected to the external laser main body equipment. The operator installs the turning tool inside the mounting base 207, and then the main bevel gear 108 rotates. Through the engagement between the main bevel tooth 108 and the bevel tooth 107, the bevel tooth 107 drives the crossbar 104 to rotate, and the crossbar 104 drives the plate 105 to rotate. After the reflector 106 is adjusted to a suitable irradiation angle, the main bevel tooth 108 stops rotating. Then, the tool, in conjunction with the external workpiece clamping device, cuts the workpiece. At the same time, the laser head 102 emits a laser beam, which passes through the adjusted reflector 106 and irradiates the workpiece to be cut, laser heating the workpiece. Simultaneously, a voltage is applied to the piezoelectric rod 204, causing the piezoelectric rod 204 to stretch and contract laterally. The deformed piezoelectric rod 204 pushes the two movable plates 203 to slide. When the two movable plates 203 slide, they pull the two elastic elements 205, causing the impact plate 206 to slide longitudinally and contact the top of the inner shell 002. The shell 002 generates micro-vibration, which is transmitted to the mounting base 207, causing the tool to vibrate slightly. This micro-vibration cuts the workpiece. The laser irradiation heats the workpiece and assists the tool in cutting it. When the shell 002 vibrates slightly, the rubber pad 101 between the base 001 and the shell 002 dampens the vibration, preventing the micro-vibration of the shell 002 from affecting the base 001.

[0024] The upper end of the vertical rod 103 is rotatably connected to the rod body 109. The lower end of the rod body 109 is fixedly connected to the upper end of the main bevel tooth 108. The upper end of the rod body 109 is provided with a groove 110. A protrusion 111 is slidably connected inside the groove 110. Both the protrusion 111 and the groove 110 are set as hexagonal rectangles. When the protrusion 111 rotates, it pushes the rod body 109 to rotate. At the same time, the rod body 109 drives the main bevel tooth 108 to rotate.

[0025] A spring 112 is fixedly connected to the lower end of the protrusion 111 and the bottom of the groove 110. A circular plate 113 is fixedly connected to the upper end of the protrusion 111. The operator manually pulls the circular plate 113 upward, so that the protrusion 111 slides upward inside the groove 110, and the spring 112 is stretched at the same time.

[0026] Two positioning rods 114 are fixedly connected to the lower end of the circular plate 113. Multiple positioning grooves 115 are provided at the upper end of the vertical rod 103. The positioning rods 114 are slidably connected to the positioning grooves 115. The circular plate 113 drives the positioning rods 114 to slide upward, so that the positioning rods 114 are disengaged from the positioning grooves 115, thereby releasing the restriction on the rod body 109.

[0027] The housing 002 has two slots 202 at both the top and bottom. The movable plate 203 is slidably connected to the slots 202. A spring 208 is fixedly connected between the side wall of the movable plate 203 and the inner wall of the housing 002. The movable plate 203 is guided and limited by the slots 202, and then the movable plate 203 is pushed to slide and reset by the elasticity of the spring 208.

[0028] Both sides of the housing 002 are fixedly connected to piezoelectric actuators 201. The connection end of the piezoelectric actuator 201 is electrically connected to the connection end of the piezoelectric rod 204.

[0029] In this invention, the operator installs the turning tool inside the mounting base 207. Then, the operator manually pulls the circular plate 113 upwards, causing the protrusion 111 to slide upwards within the groove 110. Simultaneously, the spring 112 is stretched, and the circular plate 113 drives the positioning rod 114 to slide upwards, disengaging the positioning rod 114 from the positioning groove 115 and releasing the restriction on the rod body 109. The operator then manually rotates the circular plate 113, causing the protrusion 111 to rotate and pushing the rod body 109 to rotate. Simultaneously, the rod body 109 drives the main... The bevel gear 108 rotates, and through the cooperation between the main bevel gear 108 and the bevel gear 107, the bevel gear 107 drives the crossbar 104 to rotate. At the same time, the crossbar 104 drives the plate 105 to rotate, adjusting the reflector 106 to a suitable illumination angle. Then, the operator manually releases the circular plate 113, and the spring 112 pulls the protrusion 111 to slide downward. At the same time, the protrusion 111 drives the positioning rod 114 to slide downward through the circular plate 113. The positioning rod 114 slides into the positioning groove 115, limiting the position of the rod 109.

[0030] After the reflector 106 is adjusted to a suitable irradiation angle, the external workpiece clamping device drives the workpiece to move, causing the tool to cut the workpiece. At the same time, the laser head 102 emits a laser beam, which irradiates the workpiece to be cut through the adjusted reflector 106, thus heating the workpiece with laser. Simultaneously, the piezoelectric driver 201 applies voltage to the piezoelectric rod 204, causing the piezoelectric rod 204 to stretch and contract laterally. The deformed piezoelectric rod 204 pushes the two movable plates 203 to slide. When the two movable plates 203 slide, they pull the two elastic elements 205, causing the impact plate 206 to slide longitudinally and contact the top of the inner shell 002. The shell 002 generates micro-vibration, which is transmitted to the mounting base 207, causing the tool to vibrate slightly, thus performing micro-vibration cutting on the workpiece. The laser irradiation heating further assists the tool in cutting the workpiece.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
