Description

Technical Field

[0001] This utility model belongs to the technical field of workpieces with end face teeth, specifically a new type of fixture for workpieces with end face teeth. Background Technology

[0002] In the field of modern mechanical manufacturing, workpieces with end-face teeth are widely used, covering many key industries such as automobile engine manufacturing, aerospace component processing, and precision instrument manufacturing. These workpieces, with their end-face tooth structure, can achieve precise positioning, efficient transmission, and reliable connection, playing a decisive role in the overall performance of equipment. Traditional fixtures can only clamp workpieces from a single direction or a limited angle. In actual processing, traditional fixtures cannot ensure that the workpiece can be firmly clamped in all directions, which can easily lead to displacement and shaking of the workpiece during processing, seriously affecting the processing accuracy, resulting in a higher product defect rate and increased production and time costs. Furthermore, workpieces with teeth on the end face come in various specifications and have significantly different diameters. Traditional fixtures are usually designed with fixed dimensions or only have limited adjustment functions. When dealing with workpieces with teeth on the end face of different diameters, it is necessary to frequently change the entire set of fixtures, which is cumbersome, time-consuming, and labor-intensive, greatly reducing production efficiency. At the same time, frequent fixture changes may also further affect the stability of machining accuracy due to factors such as installation errors.

[0003] Therefore, a novel fixture for workpieces with end face teeth is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a novel fixture for workpieces with end face teeth, which has the advantages of being able to clamp the end face teeth from all directions and being able to adapt and adjust to end face teeth of different diameters.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel fixture for workpieces with end face teeth, comprising an operating table, wherein a fixture assembly is mounted on the surface of the operating table; The fixture assembly includes a positioning plate, which is mounted on the surface of the operating table. Multiple connecting plates are evenly distributed on the surface of the positioning plate, with two connecting plates forming a group. A fixture plate is provided between each group of connecting plates. Adjusting blocks are symmetrically mounted on the surface of the fixture plate. Adjusting grooves that match the adjusting blocks are opened on the surface of the connecting plates. The fixture plate is slidably connected between the two connecting plates through the adjusting blocks and the adjusting grooves. An inclined block is mounted on the side of the fixture plate away from the center point of the positioning plate. A pushing block is slidably connected in a groove opened on the surface of the operating table. The inclined block and the pushing block are in contact. A drive assembly is mounted on the surface of the operating table.

[0006] Preferably, several rubber pads are evenly installed on the surface of the positioning disk.

[0007] Preferably, a soft pad is installed on the side surface of the clamping plate closest to the center point of the positioning disk.

[0008] Preferably, a guide rod is slidably connected in the through hole opened on the surface of the adjusting block, and both ends of the guide rod pass through the adjusting block and are installed in the adjusting groove opened on the surface of the connecting plate.

[0009] Preferably, the push block and the inclined block correspond one-to-one.

[0010] Preferably, the drive assembly includes a multi-plate, with one end of each of the multiple push blocks penetrating the operating table and extending to the bottom of the operating table, and all connected to the multi-plate located at the bottom of the operating table.

[0016] 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.

[0017] like Figures 1 to 4 As shown, this utility model provides a novel fixture for workpieces with end face teeth, including an operating table 1, on the surface of the operating table 1, a fixture assembly 2 is mounted; The clamp assembly 2 includes a positioning disk 21. The positioning disk 21 is mounted on the surface of the operating table 1. Multiple connecting plates 22 are evenly distributed on the surface of the positioning disk 21, with two connecting plates 22 forming a group. A clamping plate 23 is provided between each group of connecting plates 22. Adjusting blocks 24 are symmetrically mounted on the surface of the clamping plate 23. Adjusting grooves adapted to the adjusting blocks 24 are formed on the surface of the connecting plates 22. The clamping plate 23 is slidably connected between the two connecting plates 22 through the adjusting blocks 24 and the adjusting grooves. An inclined block 28 is mounted on the side of the clamping plate 23 away from the center point of the positioning disk 21. A push block 29 is slidably connected in a groove on the surface of the operating table 1. An inclined block 28 fits into the push block 29. A drive assembly 3 is installed on the surface of the operating table 1. Multiple evenly distributed clamping plates 23 can apply clamping force to the workpiece from different directions simultaneously, ensuring that the workpiece with end face teeth can be firmly fixed at all angles. This all-round clamping method can effectively avoid the workpiece displacement and shaking problems caused by traditional clamping in a single or limited direction, greatly improve the stability of the workpiece during processing, provide a strong guarantee for high-precision processing, and significantly reduce the product defect rate.

[0018] Specifically, several rubber pads 25 are evenly installed on the surface of the positioning disk 21, which can stabilize the position of the workpiece with end face teeth and increase its friction.

[0019] like Figures 1 to 4 As shown, a soft pad 26 is installed on the side surface of the clamping plate 23 near the center point of the positioning disk 21, which can protect the workpiece with end face teeth during clamping.

[0020] Furthermore, a guide rod 27 is slidably connected in the through hole opened on the surface of the adjusting block 24. Both ends of the guide rod 27 pass through the adjusting block 24 and are installed in the adjusting groove opened on the surface of the connecting plate 22, which can guide the movement of the adjusting block 24.

[0021] It is worth noting that push block 29 corresponds one-to-one with inclined block 28.

[0022] like Figures 1 to 4 As shown, the drive assembly 3 includes a multi-plate 31. One end of each of the multiple push blocks 29 passes through the operating table 1 and extends to the bottom of the operating table 1, and is connected to the multi-plate 31 located at the bottom of the operating table 1. A lead screw 32 is threaded into a threaded hole on the surface of the multi-plate 31. Both ends of the lead screw 32 pass through the multi-plate 31 and are rotatably connected to the surface of the operating table 1. A drive motor 33 is installed in a cavity inside the operating table 1. The output end of the drive motor 33 passes through the cavity inside the operating table 1 and is connected to one end of the lead screw 32, thereby controlling the clamping position and enabling clamping of workpieces with end face teeth of different diameters, and precisely controlling the adaptation and adjustment of workpieces of different diameters.

[0023] It is worth emphasizing that multiple limiting rods 34 are slidably connected to the surface of the multi-plate 31. Both ends of the limiting rods 34 penetrate the multi-plate 31 and are installed on the surface of the operating table 1. The limiting rods 34 correspond one-to-one with the push blocks 29, thereby guiding the movement of the multi-plate 31 and preventing the multi-plate 31 from shifting position during movement.

[0024] Working principle and process: The workpiece with end face teeth to be processed is placed on the positioning plate 21. The rubber pads 25 evenly installed on the surface of the positioning plate 21 can play a preliminary buffering and anti-slip role, which helps to stabilize the initial position of the workpiece. Then, the drive assembly 3 is activated. The drive motor 33 operates, and its output drives the lead screw 32 to rotate. Since the lead screw 32 is threadedly connected to the multi-connector plate 31, the multi-connector plate 31 moves along the surface of the limiting rod 34 under the drive of the lead screw 32. The limiting rod 34 can limit the movement position of the multi-connector plate 31. The multi-connector plate 31 is connected to multiple push blocks 29, which in turn push the push blocks 29 to slide in the grooves opened on the surface of the operating table 1. As the push blocks 29 move, they push the inclined block 28. Since the inclined block 28 is mounted on the clamping plate 23, the clamping plate 23 slides along the adjustment groove on the surface of the connecting plate 22 under the action of the inclined surface. Multiple clamping plates 23 simultaneously move towards the center of the positioning disk 21, thereby clamping the workpiece with end face teeth placed on the positioning disk 21 in all directions. During this process, the soft pad 26 installed on the surface of the clamping plate 23 near the center point of the positioning disk 21 can prevent the clamping plate 23 from directly contacting the workpiece and causing damage, while enhancing the stability of clamping. Under the guidance of the guide rod 27, the adjusting block 24 ensures the stability of the clamping plate 23 during the sliding process and avoids deviation. To clamp workpieces with teeth on the end face of different diameters, simply control the position of the multi-connecting plate 31 on the lead screw 32, thereby driving the clamping plate 23 to move in position, so that the position of the clamping plate 23 can be controlled to adapt to workpieces of different diameters and achieve diameter adaptation adjustment.
