Description

Technical Field

[0001] This utility model relates to the technical field of support seat tooling mechanism, and in particular to a spherical support seat tooling mechanism. Background Technology

[0002] Currently, the company faces significant clamping challenges in processing small and medium-sized cast iron and thin-walled steel parts. These parts are characterized by minute dimensional deviations, irregular geometric shapes, and thin walls that are prone to deformation. Traditional fixed clamping methods present substantial challenges in practical applications: on the one hand, rigid clamping easily induces workpiece deformation, especially when residual deformation from previous machining is superimposed on clamping stress, leading to a cumulative deformation effect during the finishing stage, severely impacting the quality of the finished product; on the other hand, frequent fixture changes are required when dealing with workpieces of diverse specifications, increasing production costs and reducing production line flexibility. More importantly, operators need to continuously adjust the clamping during processing, which is both time-consuming and restricts production efficiency.

[0003] In existing technologies, some tooling fixtures use a fixed-angle support structure, which cannot be adaptively adjusted according to the irregular surface of the workpiece. During clamping, excessive local stress is likely to occur, which will aggravate the deformation of the workpiece. Some fixtures can achieve a certain degree of clamping adjustment, but the adjustment structure is complex, the operation is cumbersome, and the adjustment range is limited, making it difficult to meet the clamping needs of workpieces of various specifications. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of easy deformation of workpieces during clamping and poor versatility of fixtures in the existing technology, and to propose a spherical support base tooling mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spherical support base tooling mechanism, comprising a tooling base plate, a bracket and a spherical support base frame, wherein a bracket is fixedly connected to one end of the top of the tooling base plate, a floating support device is fixedly connected to the other end of the bracket, an auxiliary support device is fixedly connected to the center of the top of the tooling base plate, and the support base is mounted on the top of the bracket.

[0006] The spherical support frame includes a tooling plate, a top cover plate, a movable upper sphere, and a fixed frame.

[0007] The tooling plate has a fixed lower ball cup inside, and a movable upper ball inside the fixed lower ball cup. The upper cover plate is fixedly connected to the tooling plate by a positioning pin. A sealing ring is provided on the outer surface of the movable upper ball, and a fixing frame is fixedly connected to the top of the movable upper ball.

[0008] Furthermore, the fixing frame includes a connecting plate, the top of the connecting plate is provided with a reserved groove, the interior of the reserved groove is provided with a connecting groove, the interior of the connecting groove is provided with a lead screw, the outer surface of the lead screw is threadedly connected with a clamping and fixing assembly, one end of the lead screw is rotatably connected to the connecting groove, and the other end of the lead screw is fixedly connected to a small motor through the connecting plate.

[0009] Furthermore, the clamping and fixing assembly includes a movable block threadedly connected to the outer surface of the lead screw, a ball fixedly connected to the top of the movable block, and a limit ring fixedly connected to the upper surface of the connecting plate.

[0010] Furthermore, there are two sets of the reserved slots on the top of the connecting plate, which are symmetrically distributed.

[0011] Furthermore, the floating support device includes a support frame fixedly connected to the upper surface of the tooling base plate, and a buffer device is fixedly connected to the top of the support frame.

[0012] Furthermore, the auxiliary support device includes a support column, a damping rod is fixedly connected to the top of the support column, a shock-absorbing spring is fixedly connected to the outer surface of the damping rod, and a placement plate is fixedly connected to the top of the damping rod.

[0013] Furthermore, the auxiliary support device consists of two sets, both of which are fixedly connected to the upper surface of the tooling base plate.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, the movable upper sphere of the spherical support frame, in conjunction with the fixed lower spherical cup, effectively compensates for workpiece dimensional deviations and shape errors, reduces clamping deformation, and improves machining accuracy. It is particularly suitable for high-precision machining requirements such as thin-walled parts and irregularly shaped parts. It can adaptively adjust the angle to fit the surface of workpieces of different shapes, avoid stress concentration caused by rigid contact, and effectively prevent clamping deformation of thin-walled workpieces. The clamping and fixing components are moved by the screw of the fixing frame, and the clamping position can be adjusted according to the workpiece size, significantly improving the versatility of the tooling mechanism.

Detailed Implementation

[0022] Please see Figure 1-5 This utility model provides a technical solution: a spherical support seat tooling mechanism, including a tooling base plate 1, a bracket 2 and a spherical support seat frame 3.

[0023] The specific setup and function of its spherical support frame 3 will be discussed below.

[0024] In this implementation plan: a bracket 2 is fixedly connected to one end of the top of the tooling base plate 1, a floating support device 4 is fixedly connected to the other end of the bracket 2, an auxiliary support device 5 is fixedly connected to the center of the top of the tooling base plate 1, and a support frame 3 is located on the top of the bracket 2.

[0025] The spherical support frame 3 includes a tooling plate 31, an upper cover plate 32, a movable upper sphere 33, and a fixed frame 34.

[0026] The tooling plate 31 has a fixed lower ball cup 311 inside, and a movable upper ball 33 inside the fixed lower ball cup 311. The upper cover plate 32 is fixedly connected to the tooling plate 31 by a positioning pin 313. A sealing ring 314 is provided on the outer surface of the movable upper ball 33, and a fixing bracket 34 is fixedly connected to the top of the movable upper ball 33.

[0027] The aforementioned components achieve the following effects: The base plate 1 serves as the fundamental load-bearing component of the entire tooling mechanism, providing stable support for other components. Its bottom can be fitted with anti-slip pads or mounting holes for easy connection to the worktable of the processing equipment. The bracket 2 acts as a connector and support, fixing the spherical support frame 3 and the floating support device 4 at appropriate heights and positions, ensuring the overall structural strength of the tooling mechanism. The tooling plate 31 and the upper cover plate 32 within the spherical support frame 3 form a space to accommodate the movable upper sphere 33. The positioning pin 313 ensures precise positioning and a secure connection between the upper cover plate 32 and the tooling plate 31. The sealing ring 314 prevents dust, cutting fluid, and other impurities from entering the contact area between the movable upper sphere 33 and the fixed lower ball cup 311, ensuring its rotational flexibility and service life.

[0028] Specifically, the fixing frame 34 includes a connecting plate 341, a reserved groove 342 is provided on the top of the connecting plate 341, a connecting groove 343 is provided inside the reserved groove 342, a lead screw 344 is provided inside the connecting groove 343, a clamping and fixing assembly 345 is threadedly connected to the outer surface of the lead screw 344, one end of the lead screw 344 is rotatably connected to the connecting groove 343, and the other end of the lead screw 344 is fixedly connected to a small motor 346 through the connecting plate 341.

[0029] The effect achieved by the above components is as follows: after the small motor 346 is powered on, it drives the lead screw 344 to rotate in the connecting groove 343. Since the lead screw 344 is threadedly connected to the clamping and fixing component 345, the rotating lead screw 344 drives the clamping and fixing component 345 to move along the reserved groove 342, thereby realizing the adjustment of the clamping position of workpieces of different sizes, meeting the clamping requirements of various specifications of workpieces, and significantly improving the versatility of the tooling mechanism.

[0030] Specifically, the clamping and fixing assembly 345 includes a movable block 3451 threadedly connected to the outer surface of the lead screw 344, a ball 3452 fixedly connected to the top of the movable block 3451, and a limit ring 3453 fixedly connected to the upper surface of the connecting plate 341.

[0031] The aforementioned components achieve the following effects: the movable block 3451 moves under the drive of the lead screw 344, and its top ball 3452 can form point contact with the workpiece surface. Compared with the traditional surface contact clamping method, this effectively avoids local stress concentration on thin-walled workpieces and reduces the risk of workpiece deformation. The limiting ring 3453 restricts the movement range of the movable block 3451, preventing it from deviating from the predetermined track and ensuring the stable operation of the clamping and fixing assembly 345.

[0032] Specifically, there are two sets of reserved slots 342 on the top of the connecting plate 341, which are symmetrically distributed.

[0033] The effect achieved by the above components is that the two sets of symmetrically distributed reserved slots 342 can simultaneously install two sets of clamping and fixing components 345, which can clamp the workpiece symmetrically from both sides, so that the workpiece is subjected to uniform force, further improving the clamping stability, and at the same time expanding the range of workpiece sizes that the tooling mechanism can adapt to.

[0034] Specifically, the floating support device 4 includes a support frame 41 fixedly connected to the upper surface of the tooling base plate 1, and a buffer device 42 fixedly connected to the top of the support frame 41.

[0035] The effect achieved by the above components is as follows: the support frame 41 fixes the buffer device 42 at a suitable height. The buffer device 42 adopts a spring damping buffer structure, which can effectively absorb the vibration energy generated by the machine tool during the workpiece processing, reduce the shaking of the tooling mechanism, reduce the impact of vibration on the workpiece processing accuracy, and ensure the stability of the processing process.

[0036] Specifically, the auxiliary support device 5 includes a support column 51, a damping rod 52 is fixedly connected to the top of the support column 51, a shock-absorbing spring 53 is fixedly connected to the outer surface of the damping rod 52, and a placement plate 54 is fixedly connected to the top of the damping rod 52.

[0037] The effects achieved by the above components are as follows: the support column 51 supports the entire auxiliary support device 5, the damping rod 52 and the shock-absorbing spring 53 form a shock-absorbing structure. When the workpiece is placed on the placement plate 54, the auxiliary support device 5 can share the weight of the workpiece borne by the spherical support frame 3, reduce local pressure, and effectively buffer the vibration during the processing, further improving the stability of workpiece clamping and processing accuracy.

[0038] Specifically, there are two sets of auxiliary support devices 5, both of which are fixedly connected to the upper surface of the tooling base plate 1.

[0039] The effect achieved by the above components is that the two sets of auxiliary support devices 5 are symmetrically distributed, which can provide more balanced auxiliary support for workpieces with different shapes and center of gravity distributions, enhance the adaptability of the tooling mechanism to diverse workpieces, and ensure that the workpiece remains stable during the processing.

[0040] Working principle: When using this spherical support fixture mechanism, firstly, according to the size and shape of the workpiece to be processed, start the small motor 346. The small motor 346 drives the lead screw 344 to rotate. The lead screw 344 drives the clamping and fixing assembly 345 to move along the reserved groove 342. Adjust the distance between the two sets of clamping and fixing assemblies 345 to adapt to the size of the workpiece. Place the workpiece on the spherical support frame 3. The movable upper ball 33 rotates adaptively in the fixed lower ball cup 311, so that the clamping and fixing assembly 345 on the fixed frame 34 can fit against the surface of the workpiece, and the workpiece is clamped by the ball 3452.

[0041] Simultaneously, the lower ball cup 311 is first fixed in place by the tooling plate 31. Through the spherical cooperation between the lower ball cup 311 and the movable upper ball 33, the lower ball cup 311 is in contact with the surface of the part. The contact surface moves with the actual direction of the part. This fixation can eliminate the influence of deformation on the surface of the part. The placement plates 54 of the two sets of auxiliary support devices 5 also contact the bottom of the workpiece to share the weight of the workpiece. During the processing, when the vibration generated by the machine tool is transmitted to the tooling mechanism, the buffer device 42 of the floating support device 4 and the damping rod 52 and shock-absorbing spring 53 of the auxiliary support device 5 work together to absorb the vibration energy, reduce the shaking of the tooling mechanism, and ensure that the workpiece is processed in a stable state.
