Description

Technical Field

[0001] This utility model relates to the field of machine cover processing, specifically a clamping device for machine cover processing. Background Technology

[0002] A machine cover is a shell structure installed on the outside of mechanical equipment to provide all-round protection for key components and operating mechanisms inside the equipment. It can effectively block external pollutants such as dust, debris, and liquids from entering the equipment, preventing these pollutants from corroding and wearing down the precision parts of the equipment, thereby extending the service life of the equipment and ensuring stable operation.

[0003] During the processing of the machine cover, securing it firmly and precisely is a key step in ensuring processing quality. Currently, the most common fixing method is mechanical clamping, which uses various shaped claws or clamping blocks to clamp the machine cover from the outside, preventing it from sliding during processing.

[0004] However, for some machine covers with softer surface materials, this clamping method can cause uneven stress on the outer surface of the cover when workers install some components, resulting in indentations and deformation, which seriously affects the appearance of the cover and the quality of the product. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a clamping device for machine cover processing, so as to solve the technical problem that when workers install some components on the outer wall surface of the machine cover, the machine cover is prone to indentation and deformation due to uneven force on the surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for machining machine covers, comprising a clamping apparatus, an operating table fixed to the bottom of the clamping apparatus, a first support plate and a second support plate installed on the outer wall of the clamping apparatus, a motor installed inside the clamping apparatus, a rotating rod connected to the end of the motor, a second bevel gear and a third bevel gear installed on the outer wall of the rotating rod, two sets of first moving frames and second moving frames respectively installed on both sides of the rotating rod, a first lead screw provided on one side of the first moving frame, the end of the first lead screw connected to the first bevel gear, a second lead screw provided on one side of the second moving frame, the end of the second lead screw connected to the fourth bevel gear, and a fixed plate connected to one side of the first moving frame and the second moving frame.

[0007] By adopting the above technical solution, the problem of indentations and deformation of the machine cover due to uneven surface stress when workers install some components on the outer wall surface of the machine cover is solved. The machine cover is placed on the outside of the clamping device, and the motor indirectly drives the first and second moving frames to move. The moving first and second moving frames push the first and second support plates to move to both sides. The first and second support plates support the inner wall of the machine cover, thereby limiting and fixing the machine cover with the clamping device. It also ensures that the outer wall of the machine cover will not be locally dented or deformed when workers install mechanical parts on the outer wall of the machine cover.

[0008] The present invention is further configured such that a set of first bevel gears and a fourth bevel gear are meshed and connected to both sides of the second bevel gear and the third bevel gear.

[0009] Preferably, the two sets of first bevel gears drive the two sets of first moving frames to move to the left through the first lead screws connected to the ends, and the two sets of first moving frames jointly push the second support plate to move to one side through the fixed plate connected to one side. At the same time, the two sets of fourth bevel gears drive the second moving frame to move to the right through the second lead screws connected to the ends.

[0010] The present invention is further configured such that the inner sides of the first support plate and the second support plate are provided with slots and blocks, and the slots and blocks are matched in size.

[0011] Preferably, when the clamping device is not clamping, the first support plate and the second support plate are interlocked by slots and strips, thereby reducing the area space occupied by the first support plate and the second support plate when the machine cover is not supported.

[0012] The present invention is further configured such that the length of the card block is greater than the moving length of the first support plate, so that the card block can always contact the top surface of the clamping device.

[0013] Preferably, when the first support plate and the second support plate move to the sides of the clamping device, the clamping device supports the first support plate and the second support plate to provide force support to the top of the inner wall of the machine cover by supporting the clamping block.

[0014] The present invention is further configured such that a plurality of springs are connected to one side of the second movable frame, and the ends of the springs are connected to the fixed plate.

[0015] Preferably, when the first support plate contacts the inner wall of the machine cover, the second moving frame continues to push the second moving frame to move outward a certain distance. During the movement of the second moving frame, the second moving frame compresses the spring, causing the spring to contract, and the spring applies a force to the fixed plate, causing the fixed plate to press the first support plate outward, thereby increasing the fixing force of the first support plate on the inner wall of the machine cover.

[0016] The present invention is further configured such that a limiting post is fixed on one side of the fixed plate, a limiting block is connected to the end of the limiting post, and a moving groove is provided inside the second moving frame.

[0017] Preferably, when the first support plate contacts the inner wall of the machine cover, the movement of the second moving frame causes the limiting block connected to the end of the fixed plate to slide in the moving groove, and the second moving frame limits the fixed plate through the limiting block and the limiting post.

[0018] The present invention is further configured such that the fixed disk is conical, and the side of the fixed disk with a larger surface area is connected to the interior of the first support plate.

[0019] Preferably, when the spring contracts, it applies a compressive force to the fixed plate, and the conical fixed plate transmits the compressive force evenly to the inner wall of the first support plate.

[0020] The present invention is further configured such that the first moving frame and the second moving frame have the same overall internal structure, and the first moving frame and the second moving frame move in opposite directions.

[0021] Preferably, the two sets of first moving frames and second moving frames are located on both sides inside the clamping device, and the two sets of first moving frames and second moving frames synchronously push the second support plate and the first support plate to move to both sides of the clamping device.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention, through a clamping device, a first support plate, a second support plate, a first moving frame, and a second moving frame, solves the problem that when workers install components on the outer wall of a machine cover, the cover is prone to indentation and deformation due to uneven surface stress. The machine cover is fitted over the clamping device, and a motor indirectly drives the first and second moving frames to move. The moving first and second moving frames push the first and second support plates to move to both sides, and the first and second support plates support the inner wall of the machine cover. This allows the clamping device to limit and fix the machine cover, and prevents localized indentation and deformation of the outer wall of the machine cover when workers install mechanical parts on it.

[0024] This utility model utilizes a spring, a fixed plate, a limiting block, a limiting post, and a moving groove. When the first support plate contacts the inner wall of the machine cover, the second moving frame continues to push the second moving frame to move outward a certain distance. During the movement of the second moving frame, the second moving frame compresses the spring, causing the spring to contract, and the spring applies a force to the fixed plate, causing the fixed plate to press the first support plate outward, thereby increasing the fixing force of the first support plate on the inner wall of the machine cover.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] First embodiment:

[0035] Please see Figure 1 — Figure 4The device includes a clamping device 1, with an operating platform 4 fixed to its bottom. A first support plate 2 and a second support plate 3 are mounted on the outer wall of the clamping device 1. A motor 5 is installed inside the clamping device 1, with a rotating rod 501 connected to its end. A second bevel gear 502 and a third bevel gear 503 are mounted on the outer wall of the rotating rod 501. Two sets of first moving frames 301 and second moving frames 6 are respectively mounted on both sides of the rotating rod 501. A first lead screw 302 is provided on one side of the first moving frame 301, with a first bevel gear 303 connected to its end. A second lead screw 601 is provided on one side of the first moving frame 6, with a fourth bevel gear 602 connected to its end. A fixed plate 604 is connected to one side of the first moving frame 301 and the second moving frame 6. This solves the problem that when workers install some components on the outer wall of the machine cover, the machine cover is prone to indentation and deformation due to uneven force on its surface. The machine cover is placed on the outside of the clamping device 1. The motor 5 indirectly drives the first moving frame 301 and the second moving frame 6 to move. The moving first moving frame 301 and the second moving frame 6 push the first support plate 2 and the second support plate 3 to move to both sides. The first support plate 2 and the second support plate 3 support the inner wall of the machine cover, thereby limiting and fixing the machine cover with the clamping device 1. It also ensures that when workers install mechanical parts on the outer wall of the machine cover, the outer wall of the machine cover will not be locally dented or deformed.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 Both sides of the second bevel gear 502 and the third bevel gear 503 are meshed with a set of first bevel gears 303 and a set of fourth bevel gears 602. The two sets of first bevel gears 303 drive the two sets of first moving frames 301 to move to the left through the first lead screw 302 connected to the end. The two sets of first moving frames 301 jointly push the second support plate 3 to move to one side through the fixed plate 604 connected to one side. At the same time, the two sets of fourth bevel gears 602 drive the second moving frame 6 to move to the right through the second lead screw 601 connected to the end.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The inner sides of the first support plate 2 and the second support plate 3 are provided with slots 304 and blocks 305, and the slots 304 and blocks 305 are matched in size. When the clamping device 1 is not clamping, the first support plate 2 and the second support plate 3 are interlocked by the slots 304 and blocks 305, thereby reducing the area space occupied by the first support plate 2 and the second support plate 3 when the machine cover is not supported.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3The length of the clamping block 305 is greater than the moving length of the first support plate 2, so that the clamping block 305 can always contact the top surface of the clamping device 1. When the first support plate 2 and the second support plate 3 move to the sides of the clamping device 1 respectively, the clamping device 1 supports the clamping block 305, so that the first support plate 2 and the second support plate 3 can provide force support to the top of the inner wall of the machine cover.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 Multiple sets of springs 603 are connected to one side of the second moving frame 6, and the ends of the springs 603 are connected to the fixed plate 604. When the first support plate 2 contacts the inner wall of the machine cover, the second moving frame 6 continues to push the second moving frame 6 to move outward a certain distance. During the movement of the second moving frame 6, the second moving frame 6 squeezes the spring 606, causing the spring 606 to contract, and the spring 606 applies a force to the fixed plate 604, causing the fixed plate 604 to squeeze the first support plate 2 outward, thereby increasing the fixing force of the first support plate 2 on the inner wall of the machine cover.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 A limiting post 606 is fixed on one side of the fixed plate 604, and a limiting block 605 is connected to the end of the limiting post 606. A moving groove 607 is provided inside the second moving frame 6. When the first support plate 2 contacts the inner wall of the machine cover, the movement of the second moving frame 6 causes the limiting block 605 connected to the end of the fixed plate 604 to slide in the moving groove 607. The second moving frame 6 limits and controls the fixed plate 604 through the limiting block 605 and the limiting post 606.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The fixed plate 604 is tapered, and the side with the larger surface area of ​​the fixed plate 604 is connected to the inside of the first support plate 2. When the spring 603 contracts, the spring 603 will apply a compressive force to the fixed plate 604. The tapered fixed plate 604 will evenly transmit the compressive force to the inner wall of the first support plate 2.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The first moving frame 301 and the second moving frame 6 have the same internal structure, and the first moving frame 301 and the second moving frame 6 move in opposite directions. The two sets of first moving frames 301 and second moving frames 6 are located on both sides inside the clamping device 1, and the two sets of first moving frames 301 and second moving frames 6 synchronously push the second support plate 3 and the first support plate 2 to move to both sides of the clamping device 1.

[0043] Second embodiment:

[0044] Please see Figure 5The second moving frame 6 has two sets of limiting rods 7 installed inside it, and the limiting rods 7 pass through the second moving frame 6. The limiting rods 7 limit the movement of the second moving frame 6. The two sets of limiting rods 7 are installed inside the second moving frame 6 in a diagonal arrangement. The diagonally arranged limiting rods 7 can not only limit the translation of the second moving frame 6, but also effectively resist the torque that causes the second moving frame 6 to flip during the movement. When the second moving frame 6 is subjected to an external force and attempts to flip, the diagonally arranged limiting rods 7 will generate reaction forces in two different directions, preventing the second moving frame 6 from changing angle around any point, making the second moving frame 6 more stable during the movement.

[0045] In practical operation, the present invention works as follows: First, the cover is placed over the clamping device 1. The motor 5 drives the second bevel gear 502 and the third bevel gear 503 to rotate via the drive rod 501. Both sides of the second bevel gear 502 and the third bevel gear 503 are connected to first bevel gears 303 and fourth bevel gears 602. The two sets of first bevel gears 303 drive the two sets of first moving frames 301 to the left via the first lead screw 302 connected to their ends. The two sets of first moving frames 301 jointly push the second support plate 3 to one side via the fixed plate 604 connected to one side. Simultaneously, the two sets of fourth bevel gears 602 drive the second moving frame 6 to the right via the second lead screw 601 connected to their ends. Furthermore, the second moving frame 6 pushes the first support plate 2 through the fixed plate 604 connected to its end, thereby causing the first support plate 2 and the second support plate 3 to move to both sides until the first support plate 2 and the second support plate 3 contact the inner wall surface of the machine cover. When the first support plate 2 contacts the inner wall of the machine cover, the second moving frame 6 continues to push the second moving frame 6 to move outward a certain distance. During the movement of the second moving frame 6, the second moving frame 6 compresses the spring 606, causing the spring 606 to contract, and the spring 606 applies a force to the fixed plate 604, causing the fixed plate 604 to press the first support plate 2 outward, thereby increasing the fixing force of the first support plate 2 on the inner wall of the machine cover.
