[0005] To address the shortcomings of existing technologies, this utility model provides a cutting device for processing large mechanical parts, which solves the problem that the fixing effect obtained by pressing and fixing parts from above may be poor, and some parts may be heavy, thus increasing the difficulty of moving the parts.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a cutting device for processing large mechanical parts, comprising two support platforms, a set of square grooves through the top of each of the two support platforms, a moving component at the bottom of each of the two support platforms, and a clamping component at the top of each of the two support platforms.

[0007] The movable component includes a mounting frame, on the inner wall of which a set of rotating rollers are rotatably mounted, the rotating rollers being positioned directly below the square groove;

[0008] The clamping assembly includes a pressure plate, with brackets fixedly installed on both sides of the outer wall of the pressure plate.

[0009] Preferably, two first vertical plates are rotatably mounted on the outer wall of the second rotating rod, and one end of the outer wall of each of the two first vertical plates is fixedly connected to the outer wall of the pressure plate. A worm gear is fixedly sleeved on the outer wall of the second rotating rod, and a worm is meshed on the outer wall of the worm gear. A second vertical plate is fixedly mounted on the top of the pressure plate, and one end of the outer wall of the worm is rotatably mounted on the outer wall of the second vertical plate.

[0010] Preferably, a first C-shaped frame is fixedly installed at the top of the support platform. A threaded rod is threaded through the top of the first C-shaped frame. The output end of the threaded rod is rotatably connected to the top of the pressure plate. Two limiting slide rods slide through the top of the first C-shaped frame.

[0014] Beneficial effects

[0015] This utility model provides a cutting device for processing large mechanical parts. Compared with the prior art, it has the following advantages:

[0016] 1. This cutting equipment for processing large mechanical parts, when it is necessary to clamp and fix the parts, first rotates the threaded rod, which drives the pressure plate to move downwards, clamping the parts below. Then, rotates the worm gear, which drives the worm wheel and the second rotating rod to rotate. The second bevel gears fixed at both ends of the outer wall of the second rotating rod will rotate together, so the rotation of the second bevel gear will drive the first bevel gear and the first rotating rod to rotate. The side plates fixedly sleeved on the outer wall of the first rotating rod will change angle with the rotation of the first rotating rod, clamping the parts from both sides towards the middle, realizing the lateral clamping function. The side plates on both sides and the pressure plate above apply force to the parts from different directions, thereby improving the clamping effect of the parts and reducing the probability of the parts shaking during the cutting process.

[0017] 2. When adjusting the position of a large mechanical part on the support platform using this cutting equipment, the part's weight makes it difficult to move. In this case, an electric push rod mounted on the inner wall of the support platform can be activated. The electric push rod moves the mounting frame upwards. A set of rotating rollers mounted on the inner wall of the mounting frame, positioned directly below a square slot, passes through the slot and contacts the bottom of the part placed at the top of the support platform as the mounting frame moves upwards. At this point, the rotating rollers lift the part, significantly reducing friction between the part and the support platform, thus simplifying the movement of the part. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides two technical solutions:

[0028] Figures 1-7 The first embodiment is shown: a cutting device for processing large mechanical parts, including two support platforms 1, a set of square grooves 2 are opened through the top of each of the two support platforms 1, a moving component 3 is provided at the bottom of each of the two support platforms 1, and a clamping component 4 is provided at the top of each of the two support platforms 1, which can clamp and fix the two sides of the cutting position of the part respectively to prevent the part from falling after cutting.

[0029] The movable component 3 includes a mounting frame 33, on the inner wall of which a set of rotating rollers 34 are rotatably mounted. The rotating rollers 34 are located directly below the square groove 2. The top height of the rotating rollers 34 is higher than the top height of the mounting frame 33, and they can pass through the square groove 2, so that the rotating rollers 34 are higher than the top of the support platform 1, thereby lifting the parts on the support platform 1. The rotating rollers 34 can rotate, thus reducing the friction of the parts on the support platform 1.

[0030] The clamping assembly 4 includes a pressure plate 44. Supports 45 are fixedly installed on both sides of the outer wall of the pressure plate 44. First rotating rods 47 are rotatably installed on the inner walls of both supports 45. Side plates 46 are fixedly sleeved on the outer walls of both first rotating rods 47. Rubber pads are provided on the outer walls of both the side plates 46 and the pressure plate 44. These rubber pads increase friction on the parts and also act as a buffer, absorbing and reducing the energy transmitted to the parts by vibrations, thus reducing the impact of vibrations on the parts and making the cutting process smoother. One end of the outer wall of each of the two first rotating rods 47 penetrates the outer wall of the support 45 and is fixedly installed with a first bevel gear 48. Second bevel gears 49 are meshed on the outer walls of both first bevel gears 48. A second rotating rod 411 is fixedly installed between the opposite sides of the two second bevel gears 49.

[0031] Two first vertical plates 410 are rotatably mounted on the outer wall of the second rotating rod 411. One end of the outer wall of each of the two first vertical plates 410 is fixedly connected to the outer wall of the pressure plate 44. A worm gear 413 is fixedly sleeved on the outer wall of the second rotating rod 411. A worm 414 is meshed on the outer wall of the worm gear 413. When the worm 414 rotates, it can drive the worm gear 413 to rotate. The worm gear 413 and the worm 414 have self-locking properties, which can prevent the worm gear 413 from rotating arbitrarily. A second vertical plate 415 is fixedly mounted on the top of the pressure plate 44. One end of the outer wall of the worm 414 is rotatably mounted on the outer wall of the second vertical plate 415. The worm 414 has a certain damping on the second vertical plate 415 to prevent the worm 414 from rotating arbitrarily on the second vertical plate 415.

[0032] A first C-shaped frame 41 is fixedly installed at the top of the support platform 1. A threaded rod 42 is threaded through the top of the first C-shaped frame 41. The output end of the threaded rod 42 is rotatably connected to the top of the pressure plate 44. Two limiting slide rods 43 slide through the top of the first C-shaped frame 41. The output ends of the two limiting slide rods 43 are fixedly connected to the pressure plate 44. When the threaded rod 42 rotates, it can drive the pressure plate 44 to rise and fall. The limiting slide rods 43 can limit the pressure plate 44, so that the pressure plate 44 can only move up and down.

[0033] Figures 1-7 The second embodiment is shown. The main difference from the first embodiment is that two mounting plates 31 are fixedly installed on the inner wall of the support platform 1. Electric push rods 32 are fixedly installed on the top of the two mounting plates 31. The output ends of the two electric push rods 32 are fixedly connected to the bottom end of the mounting frame 33. The electric push rods 32 are existing technology and can drive the mounting frame 33 to move up and down.

[0034] A second C-shaped frame 5 is fixedly installed on the top of one of the two support platforms 1. An electric slide rail 6 is fixedly installed on the inner wall of the second C-shaped frame 5. A cutting device 7 is fixedly installed on the output end of the electric slide rail 6. The electric slide rail 6 is existing technology and can drive the cutting device 7 to move.

[0035] There is a certain gap between the two support platforms 1 on opposite sides. The cutting device 7 is set in the gap. The cutting device 7 is the prior art. It is mainly driven by a motor to rotate the cutting blade, thereby cutting the parts. When cutting, the cutting device 7 moves in the gap between the two support platforms 1, which can prevent it from hitting other objects during cutting.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, when cutting parts, the parts are first placed on the two support platforms 1, so that the part to be cut is below the cutting device 7. When clamping and fixing the parts, the threaded rods 42 on both sides are rotated first. The threaded rods 42 drive the clamping plate 44 to move downward, clamping the parts below. Then, the worm gear 414 is rotated, which drives the worm wheel 413 and the second rotating rod 411 to rotate. The second bevel gear 49, which is fixed at both ends of the outer wall of the second rotating rod 411, will rotate together. Therefore, the rotation of the second bevel gear 49 will drive the first bevel gear 48 and the first rotating rod 47 to rotate. The side plates 46 fixedly sleeved on the outer wall of the first rotating rod 47 will change angle as the first rotating rod 47 rotates, clamping the parts from both sides to the middle, realizing the lateral clamping function. The side plates 46 on both sides and the pressure plate 44 above apply force to the parts from different directions, thereby improving the clamping effect of the parts and reducing the probability of the parts shaking during the cutting process. Then, the cutting device 7 and the electric slide rail 6 are turned on. The electric slide rail 6 drives the cutting device 7 to move, so that the parts can be cut. When it is necessary to adjust the position of large parts on the support platform 1, it is not easy to move them due to their large weight. At this time, the electric push rod 32 installed on the mounting plate 31 on the inner wall of the support platform 1 can be activated. The electric push rod 32 drives the mounting frame 33 to move upward. A set of rotating rollers 34 rotatably installed on the inner wall of the mounting frame 33 is located directly below the square groove 2. When the mounting frame 33 moves upward, the rotating rollers 34 will pass through the square groove 2 and contact the bottom of the parts placed at the top of the support platform 1. At this time, the rotating roller 34 can lift the parts, which greatly reduces the friction between the parts and the support platform 1, thereby reducing the difficulty of moving the parts. After the position of the parts is adjusted, the electric push rod 32 is turned on. The electric push rod 32 drives the rotating roller 34 to descend below the support platform 1, so that the parts contact the top of the support platform 1, thereby improving the stability of the parts.
