They are used to securely connect two or more components together. In various machine tool, construction machinery, automobile, and aircraft manufacturing industries, connecting screws are used to assemble numerous components such as engines, transmissions, and vehicle frames, ensuring a secure connection between the various components to maintain the normal operation of the mechanical equipment. As an important mechanical fastener, connecting screws play a crucial role in many fields.
[0003] However, existing technologies still have the following problems:
[0004] First, the connecting screw blanks are machined using milling and other mechanical processes, which generates impact forces. These impact forces increase the scrap rate of unstable or misaligned connecting screw blanks. Existing processing equipment on the market is not convenient for effectively clamping and fixing connecting screw blanks, which reduces production quality and makes it impossible to guarantee the quality of connecting screws.
[0005] Secondly, the outer surface of the connecting screw blank needs to be tapped during the processing. Inadequate tapping will result in substandard quality of the connecting screw blank. Existing processing equipment on the market is not convenient to effectively tap the connecting screw blank, and its practicality is low.
[0006] To address the aforementioned problems, the inventors have proposed a connecting screw processing device to solve these problems. Utility Model Content

[0019] 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.
[0020] Example: Figure 1-4As shown, this utility model provides a connecting screw processing device, including a table 1, a base 4 fixedly connected to the top surface of the table 1, a through groove 5 formed in the middle of the top surfaces of the table 1 and the base 4, wherein a die sleeve 6 is fixedly connected to the inner wall of the upper through groove 5, a clamping device 2 is provided above the table 1, the clamping device 2 includes a fixing frame 201, a first support plate 202 fixedly connected to the bottom surface of the fixing frame 201, a second support plate 203 fixedly connected to the top surface of the fixing frame 201, a lifting device 3 fixedly connected to the second support plate 203 and the top surface of the table 1, a first motor 204 fixedly connected to the upper inner wall of the second support plate 203, a threaded rod 205 fixedly connected to the output end of the first motor 204, a threaded block 206 threadedly sleeved on the outer surface of the threaded rod 205, and the outer surface of the threaded block 206... The surface is in contact with the inner wall of the first support plate 202. The thread block 206 will move downward along the threaded rod 205, ensuring the stability of the movement of the thread block 206 and making it only able to move in a straight line up and down. The bottom surface of the thread block 206 is fixedly connected to the third support plate 208. The bottom surface of the third support plate 208 is fixedly connected to three first fixed plates 209 arranged in a ring array. The bottom surface of the first support plate 202 is fixedly connected to multiple second fixed plates 211 arranged in a ring array. The lower part of the outer surface of the first fixed plate 209 is rotatably connected to two rotating plates 210. A clamping plate 212 is rotatably connected between every two adjacent first fixed plates 209. The lower part of the outer surface of the three clamping plates 212 has an arc-shaped cross section. The middle part of the outer surface of the clamping plate 212 is rotatably connected to the side of the two rotating plates 210 that is close to it.
[0021] When the screw block 206 moves upward, through the linkage of the above-mentioned series of connecting components, the clamping plate 212 will close inward under the action of the rotating plate 210, clamping and fixing the connecting screw.
[0022] The lifting device 3 includes four support rods 31. The bottom ends of the four support rods 31 are fixedly connected to the top surface of the platform 1. A top plate 32 is fixedly connected to the top surface of the four support rods 31. A connecting plate 33 is fixedly connected to the outer surface of the four support rods 31. A fourth support plate 34 is fixedly connected to the top surface of the top plate 32. A second motor 35 is fixedly connected to the lower inner wall of the fourth support plate 34. A lead screw 36 is fixedly connected to the output end of the second motor 35. A housing 37 is threaded onto the outer surface of the lead screw 36. A limit plate 39 is fixedly connected to the top of the housing 37. The outer surface of the housing 37 and the connecting plate 33 are movably connected through each other. When the lead screw 36 rotates, the housing 37 will move up and down along the lead screw 36. The housing 37 can maintain linear motion and will not deviate during the movement along the lead screw 36. A threaded groove 38 is opened on the inner wall of the housing 37 to cooperate with the housing 37. The bottom end of the housing 37 is fixedly connected to the top end of the second support plate 203.
[0023] When the housing 37 moves downward, it will cause the entire connecting screw blank to descend, which can effectively perform tapping operations on the connecting screw.
[0024] Working principle: When it is necessary to clamp the connecting screw, the first motor 204 is started. The output end of the first motor 204 drives the threaded rod 205 to rotate. Since the threaded block 206 is threaded onto the outer surface of the threaded rod 205, when the threaded rod 205 rotates, the threaded block 206 will move downward along the threaded rod 205, ensuring the stability of the movement of the threaded block 206 and making it only able to move in a straight line up and down. When the threaded block 206 moves downward, the third support plate 208 fixedly connected to its bottom surface also moves downward. The three first fixed plates 209 fixedly connected to the bottom surface of the third support plate 208 in a circular array also move downward. As the first fixed plates 209 move downward, through the rotation transmission of the rotating plate 210, the clamping plate 212 will open outward to make room for the connecting screw. When the threaded block 206 moves upward, through the linkage of the above series of connecting components, the clamping plate 212 will close inward under the action of the rotating plate 210, thereby achieving the purpose of clamping and fixing the connecting screw.
[0025] The through slot 5 provides space for subsequent machining of the connecting screw. The die sleeve 6, as above, plays an auxiliary positioning and guiding role in machining, ensuring that the machined thread meets the requirements and improving machining accuracy. The second motor 35 is started, and the output end of the second motor 35 drives the lead screw 36 to rotate. When the lead screw 36 rotates, the housing 37 will move up and down along the lead screw 36. The housing 37 can maintain linear motion and will not deviate during the movement along the lead screw 36. The top of the housing 37 is fixedly connected to the limit plate 39 to prevent the housing 37 from detaching from the lead screw 36 during the upward movement. When the housing 37 moves downward, it will drive the entire connecting screw blank to descend, thereby achieving the purpose of effectively tapping the connecting screw.
[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
