Description
Technical Field
[0001] This utility model relates to the field of tooling technology for casting parts, and in particular to a tooling for irregularly shaped casting parts. Background Technology
[0002] In the production and processing of irregularly shaped castings, traditional tooling often faces numerous challenges in positioning and clamping due to their complex structure and irregular shape. Existing tooling positioning components often lack sufficient flexibility in position adjustment, making it difficult to adapt to irregularly shaped parts of different sizes and shapes. Furthermore, when in contact with the casting surface, excessive frictional resistance can lead to difficulties in fine-tuning the position, and even cause scratches on the casting surface, severely affecting pre-positioning accuracy and ease of operation. Simultaneously, traditional clamping mechanisms suffer from poor clamping stability for irregularly shaped parts; the position locking effect of clamping components such as V-clamps is unsatisfactory, and loosening is prone to occur. Moreover, when adjusting the machining angle of the casting is required, the adjustment process is cumbersome, the angle fixation reliability is insufficient, and poor guidance can easily lead to positioning deviation. These shortcomings fail to meet the requirements for precise positioning, stable clamping, and flexible angle adjustment during the processing of irregularly shaped castings, significantly restricting the improvement of production efficiency and casting processing quality. Therefore, we have introduced a new tooling for irregularly shaped castings. Utility Model Content
[0003] The main purpose of this utility model is to provide a tooling for irregularly shaped castings, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tooling for irregularly shaped castings includes a mounting base. The mounting base has four fixing holes at its upper corners, and threaded holes at the front and rear of its upper center. Clamping mechanisms are detachably installed inside each of the four threaded holes via screws and nuts. A positioning seat is located at the upper center of the mounting base. Movable grooves are located at the upper left and upper right of the positioning seat. Lead screws are installed inside each of the two movable grooves, extending through and to the left and right sides of the positioning seat, respectively. Positioning components are movably installed on the outer surfaces of both lead screws, and handles are provided on the opposite sides of both lead screws.
[0005] Preferably, the clamping mechanism includes a placement seat, a rotating seat rotatably mounted on the inner surface of the placement seat, a pull rod movably mounted at the front end of the rotating seat, a limit block at the rear end of the pull rod, a pull block at the front end of the pull rod, a spring movably sleeved on the outer surface of the pull rod, an installation block fixedly mounted on the upper end of the rotating seat via a support column, a limit post movably mounted on one end of the installation block via an installation hole, a V-shaped clamp at the end of the limit post away from the installation block, a threaded rod movably mounted on the upper end of the installation block, a rotating block at the upper end of the threaded rod, and a limit clamp movably mounted on the lower end of the threaded rod via a movable sleeve.
[0006] Preferably, the front part of the outer surface of the spring and the rear part of the outer surface are fixedly connected to the limiting block and the inner wall of the placement seat, respectively, and the limiting block is slidably connected to the inner wall of the placement seat through the guide block.
[0007] By adopting the above technical solution, the elastic force of the spring can push the limiting block to always keep it pressed against the workpiece, while the sliding cooperation between the guide block and the placement seat ensures that the limiting block moves stably only in the set direction and avoids deviation.
[0008] Preferably, the limiting block is in close contact with the outer surface of the rotating seat.
[0009] By adopting the above technical solution, the limiting block can effectively brake the rotating seat, preventing the rotating seat from rotating unexpectedly during workpiece processing or positioning.
[0010] Preferably, the inner surface of the limiting clamp is tightly fitted to the upper part of the outer surface of the limiting post.
[0011] By adopting the above technical solution, rigid connection and positioning of the two can be achieved through the tight fit between the limiting clamp and the limiting post.
[0012] Preferably, the positioning component includes a movable block, a support frame is provided at the upper end of the movable block, a fixed column is fixedly installed at one end of the support frame, a universal groove is provided at the right end of the fixed column, a universal ball is provided on the inner surface of the universal groove, a limit plate is fixedly installed on the outer surface of the universal ball away from the fixed column through a connecting column, and a ball bearing is provided at the end of the limit plate away from the universal ball.
[0013] By adopting the above technical solution: the cooperation between the universal ball and the universal groove allows the limiting plate to flexibly adjust its angle to adapt to the irregular surface of the irregular casting; the design of the ball reduces the frictional resistance between the limiting plate and the workpiece surface, making it easy to fine-tune the workpiece position during the positioning process, while avoiding scratching the workpiece surface, thus taking into account both positioning flexibility and surface protection function.
[0014] Preferably, the support frame is movably mounted on the outer surface of the lead screw via a movable block.
[0015] By adopting the above technical solution, rotating the lead screw can drive the movable block to move along the lead screw axis, thereby driving the support frame to move synchronously, realizing the precise adjustment of the position of the positioning component to adapt to irregularly shaped castings of different sizes.
[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The movable block is driven by a lead screw to move along the movable groove to achieve adjustable position. With the flexible rotation of the universal ball in the universal groove, the limiting plate can adaptively adjust the angle according to the irregular surface of the irregular casting. The ball design reduces the contact resistance with the casting surface by means of rolling friction, which not only facilitates the fine adjustment of the casting position in the pre-positioning stage, but also effectively avoids scratching the casting surface. The positioning component can accurately adapt to irregular structures of different sizes and shapes, greatly improving the accuracy of pre-positioning and the convenience of operation. 2. The V-shaped clamp can initially fit the shape of the casting to achieve auxiliary positioning. The rotating block drives the limit clamp to move down and fit tightly with the limit post through the threaded rod, which can lock the position of the limit post to ensure the stable clamping of the V-shaped clamp on the casting. At the same time, by pulling the pull block, the limit block is driven to overcome the spring force and disengage from the rotating seat, which can flexibly adjust the angle of the rotating seat. After releasing the pull block, the spring returns to its original position and pushes the limit block to fit back into the rotating seat to achieve angle fixation. The guide block can also ensure that the limit block moves smoothly and does not deviate. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] Please see Figure 1-4 This utility model provides a technical solution: A tooling for irregularly shaped castings includes a mounting base 1. Fixing holes 2 are provided at the four corners of the upper end of the mounting base 1. Threaded holes 3 are provided at the front and rear of the upper middle part of the mounting base 1. Clamping mechanisms 4 are detachably installed inside each of the four threaded holes 3 via screws and nuts. A positioning base 5 is provided at the upper middle part of the mounting base 1. Movable grooves 6 are provided at the upper left and upper right parts of the positioning base 5. Lead screws 7 are provided inside each of the two movable grooves 6. The two lead screws 7 pass through and extend to the left and right sides of the positioning base 5, respectively. Positioning components 8 are movably installed on the outer surfaces of the two lead screws 7. Handles 9 are provided on the opposite sides of the two lead screws 7.
[0023] In this embodiment, the clamping mechanism 4 includes a placement seat 40, a rotating seat 41 rotatably mounted on the inner surface of the placement seat 40, a pull rod 42 movably mounted at the front end of the rotating seat 41, a limit block 43 provided at the rear end of the pull rod 42, a pull block 44 provided at the front end of the pull rod 42, a spring 45 movably sleeved on the outer surface of the pull rod 42, an mounting block 46 fixedly mounted at the upper end of the rotating seat 41 via a support column, a limit post 47 movably mounted at one end of the mounting block 46 via a mounting hole, and a V-shaped clamp 48 provided at the end of the limit post 47 away from the mounting block 46. A threaded rod 49 is movably installed at the upper end of the mounting block 46. A rotating block 491 is provided at the upper end of the threaded rod 49. A limit clamp 492 is movably installed at the lower end of the threaded rod 49 through a movable sleeve. The front part of the outer surface of the spring 45 and the rear part of the outer surface are fixedly connected to the limit block 43 and the inner wall of the placement seat 40, respectively. The limit block 43 is slidably connected to the inner wall of the placement seat 40 through a guide block. The limit block 43 is tightly fitted to the outer surface of the rotating seat 41. The inner surface of the limit clamp 492 is tightly fitted to the upper part of the outer surface of the limit post 47.
[0024] Through the above scheme: In use, the V-clamp 48 can initially position the workpiece. Rotating the rotating block 491 drives the threaded rod 49 to rotate, causing the limiting clamp 492 to move down and fit tightly against the limiting post 47, thereby fixing the position of the limiting post 47 and ensuring the stable clamping state of the V-clamp 48 on the workpiece. When it is necessary to adjust the angle of the rotating seat 41, pulling the pull block 44 drives the pull rod 42 and the limiting block 43 to move forward, causing the limiting block 43 to separate from the rotating seat 41. At this time, the rotating seat 41 can be rotated to the required angle. After releasing the pull block 44, the elastic force of the spring 45 pushes the limiting block 43 to reset and fit tightly against the rotating seat 41 again, thus fixing the angle of the rotating seat 41. The guide block ensures that the limiting block 43 moves smoothly without deviation. The entire clamping mechanism 4, through the cooperation of multiple parts, can not only achieve reliable clamping of the workpiece, but also flexibly adjust the angle of the workpiece to adapt to different processing needs, improving the convenience of operation and positioning accuracy.
[0025] In this embodiment, the positioning component 8 includes a movable block 81, a support frame 82 is provided at the upper end of the movable block 81, a fixed column 83 is fixedly installed at one end of the support frame 82, a universal groove 84 is provided at the right end of the fixed column 83, a universal ball 85 is provided on the inner surface of the universal groove 84, and a limit plate 86 is fixedly installed on the side of the outer surface of the universal ball 85 away from the fixed column 83 through a connecting column, and a ball bearing 87 is provided at the end of the limit plate 86 away from the universal ball 85; the support frame 82 is movably installed on the outer surface of the lead screw 7 through the movable block 81.
[0026] Through the above scheme: In use, rotating the lead screw 7 can drive the movable block 81 to move along the axis of the lead screw 7, and then drive the fixed column 83, universal ball 85, limit plate 86 and other components to move synchronously through the support frame 82, so as to realize the adjustment of the overall position of the positioning assembly 8 to adapt to irregular castings of different sizes; the universal ball 85 can rotate flexibly in the universal groove 84, so that the limit plate 86 can adjust the angle according to the surface shape of the irregular casting, ensuring that the ball 87 is in full contact with the workpiece surface. The setting of the ball 87 reduces the friction between the limit plate 86 and the workpiece, which facilitates the fine adjustment of the workpiece position during the positioning process, while avoiding scratching the workpiece surface. The entire positioning assembly 8 can effectively adapt to the irregular structure of irregular castings through adjustable position and adaptive angle adjustment, realize precise positioning, and improve the versatility and use effect of the tooling.
[0027] It should be noted that this utility model is a tooling for irregularly shaped castings. In use, the tooling is first installed in the working area by using the fixing hole 2 of the mounting base 1 in conjunction with the screw and nut. If it is necessary to clamp irregularly shaped castings, the lever 9 is operated to rotate the lead screw 7. The lead screw 7 drives the movable block 81 to move axially along the lead screw 7 in the movable groove 6, which drives the positioning component 8 to move synchronously and adjust it to a position that matches the size of the casting. At this time, the universal ball 85 of the positioning component 8 rotates flexibly in the universal groove 84, so that the limiting plate 86 adaptively adjusts the angle according to the irregular surface of the casting. The ball 87 contacts the surface of the casting and reduces resistance by means of rolling friction. This not only facilitates fine adjustment of the casting position, but also avoids scratching the surface and achieves precise pre-positioning. Then, the casting is placed on the rotating seat 41 of the clamping mechanism 4. The V-clamp 48 initially fits the shape of the casting to assist in positioning. The rotating block 491 is rotated, and the threaded rod 49 rotates to drive the limiting clamp 492 to move down and fit tightly with the limiting post 47, locking the position of the limiting post 47 and allowing the V-clamp 48 to stably clamp the casting. To adjust the casting angle, pull block 44 is moved, and pull rod 42 drives limit block 43 to move forward against the elastic force of spring 45, disengaging from rotating seat 41. After rotating seat 41 is rotated to the target angle, pull block 44 is released, spring 45 resets, and pushes limit block 43 back to re-engage tightly with rotating seat 41, fixing the angle of rotating seat 41. Guide block ensures that limit block 43 moves smoothly without deviation. Throughout the process, clamping mechanism 4 and positioning component 8 work together. Clamping mechanism 4 achieves reliable clamping and flexible angle adjustment through the cooperation of multiple components. Positioning component 8 adapts to irregular structures with adjustable position and adaptive angle.
