Description

Technical Field

[0001] This utility model relates to the field of carbon ring production and processing technology, and in particular to a clamping device for processing carbon rings. Background Technology

[0002] Carbon rings, as a type of component with excellent high temperature resistance, corrosion resistance, and high strength, are widely used in many important fields such as machinery manufacturing, chemical industry, and aerospace. As industrial production demands higher performance from carbon rings, the control over their processing quality is becoming increasingly stringent. In the processing of carbon rings, clamping is a crucial step, as it directly determines the stability of the processing and the precision of the final product.

[0003] In existing technologies, the clamping mechanisms of some devices have significant limitations in terms of size adjustment. Their adjustment range is relatively narrow, making it difficult to flexibly adapt to carbon ring workpieces of different diameters. This results in poor versatility and an inability to widely meet the processing needs of various workpiece sizes. Furthermore, the control of clamping force relies entirely on the operator's personal experience and feel, lacking precise quantitative standards. This subjective control method is prone to instability in clamping force. Specifically, excessive clamping force can apply too much pressure to the carbon ring workpiece, potentially causing it to break. Conversely, insufficient clamping force may cause the workpiece to slip during processing, affecting machining accuracy and product quality. Therefore, existing technologies have significant shortcomings in terms of size adjustment and force control of clamping mechanisms, urgently requiring improvement and optimization.

[0004] The purpose of this invention is to solve the problems of poor versatility and lack of pressure monitoring in the existing technology, and to propose a clamping device for processing carbon rings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device for processing carbon rings, comprising a mounting base plate, a fixing plate, and a fixing pad.

[0006] The top of the mounting base plate is fixedly connected to the bottom of the fixing plate. The top of the fixing plate is provided with a rectangular groove, and a bidirectional lead screw is provided inside the rectangular groove. A small geared motor is fixedly installed on the outer surface of the fixing plate. The output end of the small geared motor is fixedly connected to one end of the bidirectional lead screw. The fixing pad is fixedly installed on the top of the fixing plate by bolts. A clamping mechanism is threadedly connected to the outer surface of the bidirectional lead screw. A miniature pressure sensor is provided on the inner wall of the clamping mechanism.

[0007] The clamping mechanism includes a first semi-arc plate and a second semi-arc plate. Both the first and second semi-arc plates are threadedly connected to the outer surface of the bidirectional lead screw. An adjustment structure is provided inside both the first and second semi-arc plates, and a moving plate is threadedly connected to the outer surface of the adjustment structure.

[0008] Furthermore, the first and second semi-arc plates are symmetrically distributed on the outer surface of the bidirectional lead screw, and the adjustment structure has two sets and is symmetrically distributed inside the first semi-arc plate.

[0009] Furthermore, the adjustment structure includes a groove provided on the inner wall of the first semi-arc plate, a screw provided on the inner wall of the groove, and an adjustment disc fixedly connected to the top end of the screw.

[0010] Furthermore, the movable plate is threadedly connected to the outer surface of the screw, and the end of the screw away from the adjusting disc is rotatably connected to the inner wall of the groove.

[0011] Furthermore, a connecting ring is fixedly connected to the bottom end of both the first and second semi-arc plates, and the connecting ring is threaded to the outer surface of the bidirectional lead screw.

[0012] Furthermore, the inner walls of both the first and second semi-arc plates are provided with circular grooves, and the miniature pressure sensor is fixedly installed inside the circular grooves.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a clamping device for processing carbon rings, including a mounting base plate 1, a fixing plate 2 and a fixing pad 3.

[0020] The following section will explain the specific setup and function of the clamping mechanism 4 and the miniature pressure sensor 5.

[0021] In this implementation scheme: the top of the mounting base plate 1 is fixedly connected to the bottom of the fixing plate 2. The top of the fixing plate 2 is provided with a rectangular groove 21. A bidirectional lead screw 22 is provided inside the rectangular groove 21. A small geared motor 23 is fixedly installed on the outer surface of the fixing plate 2. The output end of the small geared motor 23 is fixedly connected to one end of the bidirectional lead screw 22. The fixing pad 3 is fixedly installed on the top of the fixing plate 2 by bolts. A clamping mechanism 4 is threadedly connected to the outer surface of the bidirectional lead screw 22. A miniature pressure sensor 5 is provided on the inner wall of the clamping mechanism 4.

[0022] The clamping mechanism 4 includes a first semi-arc plate 41 and a second semi-arc plate 42. Both the first semi-arc plate 41 and the second semi-arc plate 42 are threadedly connected to the outer surface of the bidirectional lead screw 22. An adjustment structure 43 is provided inside the first semi-arc plate 41 and the second semi-arc plate 42. A movable plate 44 is threadedly connected to the outer surface of the adjustment structure 43.

[0023] The effects achieved by the above components are as follows: the mounting base plate 1 provides a stable support foundation for the entire device, ensuring that the device will not easily shake during operation; the fixing plate 2 is used to support the various components, and the rectangular groove 21 provides installation space for the bidirectional lead screw 22; the small geared motor 23 provides power for the rotation of the bidirectional lead screw 22, driving the clamping mechanism 4 to clamp or release the carbon ring; the fixing pad 3 increases the friction between the fixing plate 2 and the mounting surface, further improving the stability of the device; the clamping mechanism 4 is the core component for clamping the carbon ring, and the miniature pressure sensor 5 can monitor the clamping force in real time to ensure the rationality of the clamping effect.

[0024] Specifically, the first semi-arc plate 41 and the second semi-arc plate 42 are symmetrically distributed on the outer surface of the bidirectional lead screw 22, and the adjustment structure 43 has two sets and is symmetrically distributed inside the first semi-arc plate 41.

[0025] The effects achieved by the above components are as follows: the symmetrical distribution of the first semi-arc plate 41 and the second semi-arc plate 42 enables the carbon ring to be evenly clamped from both sides under the drive of the bidirectional lead screw 22, ensuring the carbon ring is under force balance and improving the center positioning accuracy; the two sets of symmetrically distributed adjustment structures 43 enable the adjustment of the moving plate 44 to be more stable, ensuring better adaptation to carbon rings of different specifications.

[0026] Specifically, the adjustment structure 43 includes a groove 431 provided on the inner wall of the first semi-arc plate 41, a screw 432 provided on the inner wall of the groove 431, and an adjustment disc 433 fixedly connected to the top of the screw 432.

[0027] The effects achieved by the above components are as follows: guiding function, ensuring that the movable plate 44 can only move along the direction of the groove 431; the screw 432 rotates under the rotation of the adjusting plate 433, thereby driving the movable plate 44 to move; the adjusting plate 433 facilitates the operator to rotate the screw 432, providing a convenient operating component for adjusting the position of the movable plate 44.

[0028] Specifically, the movable plate 44 is threadedly connected to the outer surface of the screw 432, and the end of the screw 432 away from the adjusting plate 433 is rotatably connected to the inner wall of the groove 431.

[0029] The effects achieved by the above components are as follows: the threaded connection between the movable plate 44 and the screw 432 allows the rotational motion of the screw 432 to be converted into the linear motion of the movable plate 44, thereby realizing the adjustment of the position of the movable plate 44 to accommodate carbon rings of different diameters; the rotational connection between the screw 432 and the inner wall of the groove 431 ensures the stability of the screw 432 during rotation, avoids deviation, and ensures the adjustment accuracy of the movable plate 44.

[0030] Specifically, the bottom ends of the first semi-arc plate 41 and the second semi-arc plate 42 are both fixedly connected with connecting rings 411, and the connecting rings 411 are threaded to the outer surface of the bidirectional lead screw 22.

[0031] The effect achieved by the above components is as follows: the connecting ring 411 serves as an intermediate component connecting the first semi-arc plate 41 and the second semi-arc plate 42 with the bidirectional lead screw 22, realizing the threaded connection between the two. When the bidirectional lead screw 22 rotates, it can drive the first semi-arc plate 41 and the second semi-arc plate 42 to move synchronously in opposite directions, ensuring the synchronicity and stability of the clamping action.

[0032] Specifically, the inner walls of the first semi-arc plate 41 and the second semi-arc plate 42 are provided with circular grooves 412, and the miniature pressure sensor 5 is fixedly installed inside the circular grooves 412.

[0033] The effects achieved by the above components are as follows: the circular groove 412 provides an installation position for the miniature pressure sensor 5, enabling it to be securely installed on the inner wall of the clamping mechanism 4; the miniature pressure sensor 5 can detect the clamping pressure of the clamping mechanism 4 on the carbon ring in real time and transmit the pressure signal to the relevant control system, so that the operator can adjust the clamping force according to the pressure value, and prevent the carbon ring from being damaged due to excessive pressure or slipping due to insufficient pressure.

[0034] Specifically, the bottom ends of the inner walls of the first semi-circular plate 41 and the second semi-circular plate 42 are both fixedly connected to a bottom pad 413, and the top of the bottom pad 413 is provided with anti-slip texture.

[0035] The effects achieved by the above components are as follows: the base pad 413 supports the carbon ring, preventing the carbon ring from directly contacting the hard surfaces of the first semi-arc plate 41 and the second semi-arc plate 42 and causing damage; the anti-slip texture increases the friction between the base pad 413 and the carbon ring, effectively preventing the carbon ring from sliding during processing and ensuring the stability and accuracy of processing.

[0036] Specifically, a protrusion 441 is fixedly connected to the outer surface of the movable plate 44 near the groove 431, and the protrusion 441 is threadedly connected to the screw 432.

[0037] The effect achieved by the above components is that the protrusion 441 increases the contact area between the moving plate 44 and the screw 432, making the threaded connection between the two more secure. When the screw 432 rotates, it can drive the moving plate 44 to move more stably, thereby improving the reliability of the adjustment of the moving plate 44.

[0038] Working principle: When in use, place the carbon ring on the base pad 413 and start the small geared motor 23. The small geared motor 23 drives the bidirectional lead screw 22 to rotate. Since the first semi-arc plate 41 and the second semi-arc plate 42 are threadedly connected to the bidirectional lead screw 22 through the connecting ring 411 and the two are symmetrically distributed, the rotation of the bidirectional lead screw 22 will cause the first semi-arc plate 41 and the second semi-arc plate 42 to move towards the middle synchronously, initially clamping the carbon ring.

[0039] According to the diameter specifications of the carbon ring, the screw 432 is rotated by rotating the adjusting disc 433, causing the moving plate 44 to move along the groove 431, further adjusting the clamping diameter of the clamping mechanism 4 to ensure the clamping effect on the carbon ring. During the clamping process, the miniature pressure sensor 5 monitors the clamping pressure in real time, and the operator adjusts the clamping force according to the pressure data to avoid improper pressure affecting the carbon ring. The anti-slip texture on the base pad 413 prevents the carbon ring from slipping, ensuring the stability of the processing. After processing is completed, the small reduction motor 23 is started in reverse, causing the first semi-arc plate 41 and the second semi-arc plate 42 to move to both sides, releasing the carbon ring and completing the operation.
