Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing technology, and in particular to an angle-adjustable clamping device for flange processing. Background Technology
[0002] Traditional flange processing clamping devices typically only provide basic flange fixing, using simple mechanical structures to hold the flange on the worktable surface to prevent significant displacement during processing. Some devices can adjust the position in one direction, but the adjustment accuracy is low, relying heavily on manual experience for judgment and operation, which is insufficient for high-precision processing requirements. Most clamping devices can only process at fixed horizontal or vertical angles. If the processing angle needs to be adjusted, the flange often needs to be removed from the device and reinstalled, which is cumbersome and time-consuming. Therefore, this application provides an angle-adjustable clamping device for flange processing to meet the requirements. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an angle-adjustable clamping device for flange processing, which solves the problem that traditional flange processing clamping devices have limited functions, mostly use simple mechanical structures to achieve basic fixation, can only perform low-precision adjustment in one direction, and require disassembly and repositioning for angle adjustment, which is cumbersome and inefficient and cannot meet the technical problems of high-precision processing requirements.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An angle-adjustable clamping device for flange processing includes a worktable on which a clamping device is mounted for processing the flange. The clamping device includes slots, with several slots equidistantly spaced on the surface of the worktable. Insert rods are slidably arranged on the inner walls of several slots. A collar is fixedly arranged on the top of the insert rod, and a slide rod is slidably arranged on the inner wall of the collar. A support plate is fixedly arranged at one end of the slide rod. A rotating rod is rotatably arranged on the inner wall of the support plate. A bidirectional reciprocating threaded groove is formed on the outer wall of the rotating rod. A first sliding groove is formed on the inner wall of the support plate. Clamping plates are threadedly connected to both ends of the bidirectional reciprocating threaded groove through threaded holes. The side of the clamping plate closest to the first sliding groove slides against the inner wall of the first sliding groove. A knob is fixedly arranged at one end of the rotating rod through the support plate.
[0005] Preferably, a fixing block is slidably provided on the surface of the workbench, a second sliding groove is provided on the inner wall of the fixing block, a limit block is slidably provided on the inner wall of the second sliding groove, a plurality of limit grooves are provided on the outer wall of the slide rod, the limit block is inserted into one of the limit grooves, a rotating shaft is rotatably provided on the inner wall of the second sliding groove, a rotating plate is fixedly provided on the outer wall of the rotating shaft, a spring is fixedly provided on the inner wall of the second sliding groove, one end of the spring is fixed to the rotating plate, the rotating plate is fixed to the limit block, a third sliding groove is provided on the inner wall of the fixing block, a pressing block is slidably provided on the inner wall of the third sliding groove, and the pressing block is fixed to the rotating plate.
[0006] Preferably, the inner wall of the collar is provided with a threaded hole, and the outer wall of the slide rod is provided with a threaded groove, and the slide rod is threadedly connected to the threaded hole through the threaded groove.
[0007] Preferably, the surface of the workbench is provided with several small holes, and a limit rod is fixedly provided on the side of the fixing block near the small holes, and the limit rod is inserted into the small holes.
[0008] Preferably, the clamping surface of the clamping plate is provided with anti-slip texture.
[0009] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, the clamping device enables lateral position adjustment along the length of the worktable. Simultaneously, the threaded transmission between the collar and the slide rod allows for precise axial distance adjustment of the support plate and the clamped flange. Furthermore, the slide rod and support plate can be rotated using the insert rod as a fulcrum, thus allowing free adjustment of the flange machining angle to meet the needs of different machining positions and angles. The matrix of small holes on the worktable surface, in conjunction with the bottom limiting rod of the fixed block, allows for precise positioning and fixation of the fixed block. Combined with the insertion of the limiting block and the slide rod's limiting groove, axial displacement of the slide rod during machining is effectively prevented, ensuring clamping stability. The bidirectional reciprocating threaded groove on the outer wall of the rotating rod enables the two clamping plates to move symmetrically in opposite directions along the first slide groove of the support plate during rotation, achieving uniform adjustment of the clamping distance.

Detailed Implementation
[0015] The adjustable clamping device for flange processing provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0016] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides an angle-adjustable clamping device for flange processing, including a worktable 1. The worktable 1 serves as the basic support platform of the device and is made of high-strength alloy material. A clamping device is also installed on the worktable 1, which is used to process the flange during processing.
[0017] Specifically, the clamping device includes several equidistant slots 2, which are evenly distributed along the length of the workbench 1. These slots are used to cooperate with the insert rods 3 in the clamping device to adjust the lateral position of the clamping device on the surface of the workbench 1, meeting the clamping requirements of flanges of different lengths and specifications. Small holes 20 are distributed in a matrix on the surface of the workbench 1 and cooperate with the limiting rods 21 at the bottom of the fixing block 11 to accurately position and fix the position of the fixing block 11, further assisting the clamping device to work stably. The insert rod 3 has a cylindrical structure, and its bottom slides in cooperation with the inner wall of the slot 2 on the surface of the workbench 1. Its position can be adjusted along the length of the slot 2 according to the flange processing position requirements. The top of the insert rod 3 is fixedly connected to the collar 4 to provide stable support for the collar 4.
[0018] The collar 4 is a ring structure with a threaded hole on its inner wall, which is threaded to the threaded groove on the outer wall of the slide rod 5. By rotating the collar 4, the slide rod 5 can be moved axially along the collar 4, thereby adjusting the distance between the support plate 6 and the flange. At the same time, the collar 4 is fixed to the insertion rod 3 and can move along the slot 2 together with the insertion rod 3 to realize the overall position adjustment of the clamping mechanism.
[0019] The slide rod 5 is a cylindrical rod with a threaded groove machined on its outer side wall, which is adapted to the threaded hole on the inner wall of the collar 4. It achieves axial movement through threaded transmission. One end of the slide rod 5 is fixedly connected to the support plate 6, providing support and position adjustment for the support plate 6. Several equidistant limiting grooves 14 are also provided on its outer side wall, which are used to cooperate with the limiting block 13 in the fixing block 11 to fix the position of the slide rod 5 and prevent the slide rod 5 from shifting during the processing.
[0020] The support plate 6 is a rectangular plate structure with a first sliding groove 9 and a mounting hole for the rotating rod 7 inside. The first sliding groove 9 is set along the length of the support plate 6 and is used to slide with the clamping plate 201 to limit the movement direction of the clamping plate 201. The mounting hole for the rotating rod 7 passes through both sides of the support plate 6 to provide rotational support for the rotating rod 7.
[0021] The rotating rod 7 is a cylindrical rod with a bidirectional reciprocating threaded groove 8 on its outer side. Both ends of the rotating rod 7 are threadedly connected to the clamping plate 201 through threaded holes. One end of the rotating rod 7 passes through the support plate 6 and is fixedly connected to a knob 10. Rotating the knob 10 can drive the rotating rod 7 to rotate. Utilizing the transmission action of the bidirectional reciprocating threaded groove 8, the two clamping plates 201 can move in opposite directions or in the opposite direction along the first sliding groove 9 to adjust the clamping distance.
[0022] The clamping plate 201 has an L-shaped plate structure. One side is connected to the bidirectional reciprocating threaded groove 8 of the rotating rod 7 through a threaded hole, and the other side slides in fit with the inner wall of the first sliding groove 9 of the support plate 6. The clamping surface of the clamping plate 201 is provided with anti-slip texture, which can increase the friction with the flange surface, prevent the flange from sliding or rotating during processing, and improve clamping stability.
[0023] Next, the fixing block 11 is installed on the surface of the workbench 1 to fix the position of the slide rod 5 and prevent the slide rod 5 from shifting due to external force during processing. The second slide groove 12 is opened inside the fixing block 11 and is set along the height direction of the fixing block 11. The inner wall is slidably provided with a limit block 13 to provide movement space for the limit block 13.
[0024] The limiting block 13 is a rectangular block structure. One end can be inserted into the limiting groove 14 on the outer wall of the slide rod 5, and the other end is fixedly connected to the rotating piece 16. Through the cooperation of the limiting block 13 and the limiting groove 14, the axial movement of the slide rod 5 can be restricted, thereby fixing the position of the slide rod 5.
[0025] The rotating shaft 15 is horizontally installed on the inner wall of the second slide groove 12, and a rotating plate 16 is fixedly installed on the outer wall. The rotating shaft 15 provides a fulcrum for the rotating plate 16, so that the rotating plate 16 can rotate around the rotating shaft 15. The rotating plate 16 is a rectangular plate structure, with one end fixed to the limiting block 13, the other end fixed to the spring 17, and the middle fixed to the rotating shaft 15. The rotating plate 16 can rotate around the rotating shaft 15 under the elastic force of the spring 17, thereby driving the limiting block 13 to engage or disengage from the limiting groove 14 of the slide rod 5.
[0026] One end of the spring 17 is fixed to the inner wall of the second slide groove 12, and the other end is fixed to the rotating plate 16. In its natural state, the elastic force of the spring 17 can push the rotating plate 16 to rotate, so that the limiting block 13 is inserted into the limiting groove 14 of the slide rod 5, thereby realizing the automatic fixing of the slide rod 5. When the pressing block 19 is pressed, the spring 17 is compressed, the rotating plate 16 rotates in the opposite direction, and drives the limiting block 13 to disengage from the limiting groove 14, thereby releasing the fixing of the slide rod 5. The third slide groove 18 is opened on the top of the fixed block 11 and communicates with the second slide groove 12. The pressing block 19 is slidably arranged on the inner wall to provide moving space for the pressing block 19. The top extends out of the surface of the fixed block 11. By pressing the pressing block 19 downward, the rotating plate 16 can be pushed to rotate around the rotating shaft 15, thereby realizing the separation of the limiting block 13 from the limiting groove 14, which facilitates the adjustment of the position of the slide rod 5. The limiting rod 21 is fixed to the bottom of the fixed block 11 and is a cylindrical structure that can be inserted into the small hole 20 on the surface of the worktable 1. By adjusting the position of the fixing block 11 on the surface of the workbench 1, the limiting rod 21 can be inserted into different small holes 20, thereby fixing the position of the fixing block 11 and adapting it to different adjustment positions of the slide rod 5.
[0027] Working principle
[0028] According to the length specifications and processing requirements of the flange to be processed, first loosen the limiting rod 21 at the bottom of the fixing block 11 (if it has been inserted into the small hole 20), slide the insertion rod 3 along the slot 2 on the surface of the workbench 1 to a suitable position, so that the entire clamping device is directly below the flange clamping area. After the adjustment is completed, move the fixing block 11 so that the limiting rod 21 at the bottom of the fixing block 11 is inserted into the corresponding small hole 20 on the surface of the workbench 1, thereby fixing the position of the fixing block 11 and preparing for the subsequent fixing of the sliding rod 5.
[0029] Rotate the knob 10 in the clamping device. The knob 10 drives the rotating rod 7 to rotate in the mounting hole of the support plate 6. Since the outer wall of the rotating rod 7 has a bidirectional reciprocating threaded groove 8, and the two clamping plates 201 are respectively connected to the threaded grooves at both ends of the rotating rod 7 through threaded holes, when the rotating rod 7 rotates, it will drive the two clamping plates 201 to move in opposite directions (i.e., move away from each other) along the first sliding groove 9 of the support plate 6 through threaded transmission, and adjust the clamping distance to be greater than the outer diameter of the flange to be processed, so as to facilitate the flange to be put in.
[0030] Place the flange to be processed between the two clamping plates 201, and rotate the knob 10 in the opposite direction again to drive the rotating rod 7 to rotate, so that the two clamping plates 201 move towards each other along the first sliding groove 9 until the clamping surface of the clamping plate 201 is in contact with the flange surface. At this time, the anti-slip texture of the clamping surface of the clamping plate 201 is in close contact with the flange surface, generating a large friction force, thus achieving the initial clamping and fixing of the flange.
[0031] If it is necessary to adjust the machining position of the flange in the axial direction (axis direction of slide bar 5), the collar 4 can be rotated. Since the threaded hole on the inner wall of the collar 4 is threadedly connected to the threaded groove on the outer wall of the slide bar 5, when the collar 4 is rotated, it will drive the slide bar 5 to move along the axial direction of the collar 4 through the threaded transmission, thereby driving the support plate 6 and the clamped flange to move together until the axial position of the flange meets the machining requirements.
[0032] If a specific angle is required for flange processing, first press down on the pressing block 19 at the top of the fixing block 11. The pressing block 19 pushes the rotating plate 16 to rotate around the rotating shaft 15. The rotating plate 16 compresses the spring 17 and simultaneously drives the limiting block 13 to move upward along the second slide groove 12, causing the limiting block 13 to disengage from the limiting groove 14 on the outer wall of the slide rod 5, thus releasing the fixation on the slide rod 5. Then, using the insertion rod 3 as a fulcrum, gently rotate the slide rod 5 and the support plate 6 to adjust the clamping angle of the flange. After the angle is adjusted to the processing requirements, release the pressing block 19. At this time, the spring 17 returns to its original state under the action of elasticity, pushing the rotating plate 16 to rotate in the opposite direction, driving the limiting block 13 to move downward along the second slide groove 12 and insert into the corresponding limiting groove 14 on the outer wall of the slide rod 5, thereby fixing the angle and position of the slide rod 5 and ensuring the stability of the flange processing angle.
[0033] During flange processing, the anti-slip texture on the clamping surface of the clamping plate 201 effectively prevents the flange from sliding. The bidirectional reciprocating threaded groove 8 of the rotating rod 7 ensures stable clamping distance. The cooperation between the limiting block 13 in the fixing block 11 and the limiting groove 14 of the sliding rod 5 prevents the sliding rod 5 from shifting axially. The cooperation between the insert rod 3 and the slot 2, and between the fixing block 11 and the small hole 20, ensures the overall position stability of the clamping device. The coordinated action of all components provides a stable clamping environment for flange processing and ensures processing accuracy.
[0034] After the flange is processed, press down on the pressing block 19 to release the fixing block 11 from fixing the slide rod 5 (if the angle needs to be adjusted, the angle can be finely adjusted). Then rotate the knob 10 to make the two clamping plates 201 move away from each other, release the flange, and finally remove the processed flange from the clamping device to complete one processing cycle.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.
[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
