Description

Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to a multi-degree-of-freedom clamping device for parts processing. Background Technology

[0002] In the field of parts processing, with the rapid development of the manufacturing industry and the increasing variety of products, the shape, specifications and processing requirements of parts are also showing a diversified trend. Parts processing clamping refers to the use of specific devices or tools to firmly fix the parts to be processed on the machine tool worktable during the machining process to ensure the accuracy and safety of the processing.

[0003] Existing parts processing clamping typically involves using clamping equipment to hold and fix the parts before using processing equipment to process them. However, current clamping equipment can only clamp parts of specific sizes or one or two specifications, and cannot be flexibly adjusted according to the specific shape and specifications of the parts. This not only easily leads to low processing efficiency, but also requires frequent replacement of clamping equipment, increasing processing costs and making it very inconvenient to use.

[0004] Therefore, it is necessary to design a multi-degree-of-freedom clamping device for parts that can be fixed in different ways according to the specifications and shape of the parts, is easy to operate, adaptable to different parts clamping and processing, improves processing efficiency, reduces processing costs, and is flexible and convenient for parts processing. Utility Model Content

[0005] To overcome the shortcomings of current clamping devices, which can only clamp parts of specific sizes or one or two specifications and cannot be flexibly adjusted according to the specific shape and specifications of the parts, resulting in low processing efficiency and frequent replacement of clamping devices, thus increasing processing costs, this utility model provides a multi-degree-of-freedom clamping device for parts processing that can select different methods to fix parts according to their specifications and shapes. It is simple to operate, easy to adapt to different parts clamping and processing, improves processing efficiency, reduces processing costs, and is flexible and convenient for parts processing.

[0006] A multi-degree-of-freedom clamping device for machining parts includes a mounting base, a lifting platform, a first motor, a connecting sleeve, a square platform, a mounting block, a second motor, a frustum, a clamping assembly, and a fixing assembly. Lifting platforms are connected to the upper sides of both the left and right sides of the mounting base. Connecting sleeves are connected to the upper parts of the lifting platforms. The first motor is connected to the right side of the connecting sleeve on the right side. A square platform is rotatably connected between the connecting sleeves. The square platform is connected to the output shaft of the first motor. A mounting block is connected to the lower side of the square platform. A second motor is connected to the middle of the mounting block. A frustum is connected to the output shaft of the second motor. A clamping assembly for clamping larger parts is provided on the square platform, and a fixing assembly for fixing parts of different shapes and sizes is provided on the frustum.

[0007] To further explain, the clamping assembly includes clamping blocks and a bidirectional lead screw. The bidirectional lead screw is rotatably connected to both the left and right sides of the square platform, and clamping blocks are threadedly connected to both the front and rear sides of the bidirectional lead screw. The clamping blocks are slidably connected to the square platform.

[0008] To further explain, friction patterns are provided on all the clamping blocks.

[0009] To further explain, the fixing component includes studs, screws, pressure blocks, fixing nuts, and locking nuts. Multiple studs are snapped onto the circular platform, and each stud is connected to a screw via threads. A pressure block is fitted between two studs at the same lateral position. Each stud is connected to a fixing nut via threads on its upper part, and the fixing nuts are in contact with the adjacent pressure blocks. Each stud is connected to a locking nut via threads on its lower part, and the locking nuts are in contact with the circular platform.

[0010] To further clarify, both the fixing nut and the locking nut are hexagonal.

[0011] To further explain, it also includes a handle; the front of the double-acting lead screw on the left side is engaged with a handle.

[0012] Beneficial effects: 1. This utility model clamps larger parts by moving the clamping blocks, then installs the studs on the round table, and then rotates the screws to move them. Then, the pressure blocks are used to fix the parts in both directions according to the thickness of the parts. Thus, different methods can be selected to fix the parts according to their specifications and shapes. The operation is simple and easy to adapt to the clamping and processing of different parts, improving processing efficiency, reducing processing costs, and making it flexible and convenient to use.

[0013] 2. This utility model starts a first motor or a second motor, which drives the square platform and the round platform to rotate, or the second motor drives the round platform to rotate, thereby driving the parts to rotate for processing. This allows for adjustable angle processing, facilitating the processing of parts at different angles, reducing errors, and improving the accuracy and quality of processing.

Detailed Implementation

[0021] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0022] A multi-degree-of-freedom clamping device for part machining, such as Figures 1-6As shown, the assembly includes a mounting base 1, a lifting platform 2, a first motor 3, a connecting sleeve 4, a square platform 5, a handle 8, a mounting block 9, a second motor 10, a frustum 11, a clamping assembly, and a fixing assembly. The lifting platform 2 is connected to the upper sides of both the left and right sides of the mounting base 1. The connecting sleeve 4 is connected to the upper part of each lifting platform 2. The first motor 3 is connected to the right side of the right connecting sleeve 4. The square platform 5 is rotatably connected between the connecting sleeves 4. The square platform 5 is connected to the output shaft of the first motor 3. The mounting block 9 is connected to the lower side of the square platform 5. The second motor 10 is connected to the middle of the mounting block 9. The frustum 11 is connected to the output shaft of the second motor 10. The square platform 5 is equipped with a clamping assembly for clamping larger parts. The clamping assembly includes a clamping block 6 and a bidirectional lead screw 7. The bidirectional lead screw 7 is rotatably connected to both the left and right sides of the square platform 5. The clamping block 6 is threaded to both the front and rear ends of the bidirectional lead screw 7. All clamping blocks 6 are slidably connected to the square platform 5. Each clamping block 6 has friction textures to facilitate clamping parts. The front of the bidirectional lead screw 7 on the left is engaged with the handle 8, which facilitates the installation and rotation of the bidirectional lead screw 7. The circular platform 11 is provided with a fixing assembly for fixing parts of different shapes and specifications. The fixing assembly includes studs 12, screws 13, pressure blocks 14, fixing nuts 15, and locking nuts 16. Four studs 12 are engaged on the circular platform 11. Each stud 12 is threaded with a screw 13. A pressure block 14 is fitted between two studs 12 at the same lateral position. The upper part of each stud 12 is threaded with a fixing nut 15, which contacts the adjacent pressure block 14. The lower part of each stud 12 is threaded with a locking nut 16, which contacts the circular platform 11. Both the fixing nut 15 and the locking nut 16 are hexagonal.

[0023] When part processing requires clamping and rotation, this device can be used. The mounting base 1 contacts the table surface, and the clamping method is selected according to the part's specifications and shape. When the part is large, it is placed on the square platform 5, making it contact the frustum 11. Then, the handle 8 is engaged with the left-side bidirectional lead screw 7. Pulling the handle 8 rotates the left-side bidirectional lead screw 7, causing the left-side clamping block 6 to move simultaneously and contact the part for clamping. The handle 8 is then removed, and the handle 8 is engaged with the right-side bidirectional lead screw 7. Pulling the handle 8 rotates the right-side bidirectional lead screw 7, causing the right-side clamping block 6 to move simultaneously. The clamping block 6 contacts the part for clamping, thereby fixing larger parts. The friction texture on the clamping block 6 increases friction to prevent the part from falling off. When the part is small and thick, the part contacts the frustum 11, and then the stud 12 is engaged with the frustum 11. Next, the locking nut 16 contacts the stud 12, and then the locking nut 16 is rotated to move and contact the frustum 11 for fixing. Then, the screw 13 is rotated to move and contact the part for fixing. Next, the pressure block 14 is placed with its opening facing down and then put on the stud 12 so that the pressure block 14 contacts the part. Then, the fixing nut 15 contacts the stud 12, and then the fixing nut 15 is rotated to move and contact the pressure block 14 for fixing. The fixing nut 15 and the locking nut 16 are both hexagonal. When the part is small and thin, the part contacts the frustum 11, then the stud 12 is engaged with the frustum 11. Next, the locking nut 16 contacts the stud 12, and then the locking nut 16 is rotated to move and contact the frustum 11 for fixation. Then, the screw 13 is rotated to move and contact the part for fixation. Next, the pressure block 14 is placed with its opening facing upwards and then fitted onto the stud 12, so that the pressure block 14 contacts the part. Then, the fixing nut 15 contacts the stud 12, and then the fixing nut 15 is rotated to move and contact the pressure block 14 for fixation. This allows for the fixation of parts of different specifications and shapes. The system can select different methods to fix parts according to their specifications and shapes. It is simple to operate, adaptable to various parts for clamping and processing, improving processing efficiency, reducing processing costs, and offering flexible and convenient use. After fixing, the first motor 3 or the second motor 10 is started. The first motor 3 drives the square platform 5 and the round platform 11 to rotate, or the second motor 10 drives the round platform 11 to rotate, thereby rotating the part for processing. The adjustable angle allows for processing at different angles, reducing errors and improving processing accuracy and quality. After use, the first motor 3 and the second motor 10 are turned off, and then the bidirectional lead screw 7 is rotated in the reverse direction via the handle 8.The screw thread causes the clamping block 6 to move in the opposite direction and reset simultaneously. The part can then be removed, or the screw 13 can be rotated in the opposite direction to disengage it from the part. Next, the fixing nut 15 can be rotated to remove it, followed by the removal of the pressure block 14, and finally the removal of the part.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
