Description

Technical Field

[0001] This utility model relates to the field of non-shaped flange processing technology, and in particular to a clamping tooling mechanism for processing non-shaped flanges. Background Technology

[0002] Because of the irregular shape and high dimensional accuracy requirements of non-standard flanges, the clamping fixture mechanism uses specific positioning elements to accurately position the flange on the processing equipment, so that the positional deviation of each processing is controlled within a very small range, ensuring that the dimensions of the processed flange meet the design requirements.

[0003] When clamping irregularly shaped workpieces, an adaptive fixture is used. An adaptive fixture is a fixture that can automatically adjust the clamping method or positioning state according to the shape, size or other characteristics of the workpiece. When in use, multiple contacts on the fixture can automatically move backward when squeezed by the irregular flange surface. When all contacts form the shape of one side of the irregular flange, the contacts are limited to maintain the specified shape, thereby adapting to the irregular shape of the irregular flange and realizing adaptive clamping of irregular flanges with different shapes.

[0004] Considering that the contacts will wear out during long-term use, they need to be replaced. However, current replacement methods often require the use of various complex tools and the removal of a large number of related components. The entire process is not only time-consuming but also requires a high level of technical skill from the operators. Therefore, a clamping fixture mechanism for processing irregular flanges is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a clamping fixture mechanism for processing irregular flanges, which aims to solve the problems in the prior art where the contacts are prone to wear and need to be replaced after long-term use, and the existing replacement requires the removal of a large number of peripheral parts with a variety of complex tools, which is time-consuming and requires highly skilled operators.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamping fixture mechanism for processing irregular flanges, comprising a base, a clamping seat slidably connected to the inner surface of the base, a moving rod elastically connected to the top of the outer surface of the clamping seat via a tension spring, the outer surface of the moving rod slidably connected to the top of the outer surface of the clamping seat, a limit cover hinged to the outer surface of the moving rod, a contact inserted into the inner surface of the moving rod, a limit block fixedly connected to the inner surface of the limit cover, the outer surface of the limit block engaging with the inner surface of the contact, a flip cover hinged to the top of the outer surface of the clamping seat, the bottom end of the outer surface of the flip cover contacting the top end of the outer surface of the limit cover, and a moving component provided on the outer surface of the base;

[0007] The movable component includes a threaded rod, the outer surface of which is rotatably connected to the inner surface of the base, the outer surface of which is threaded through and threaded to the bottom of the inner surface of the clamping seat, and a placement plate is fixedly connected to the top of the outer surface of the base.

[0008] As a further description of the above technical solution:

[0009] The right side of the flip cover is fixedly connected to the top of the outer surface of the clamping seat by bolts. A guide post is slidably connected through the top of the outer surface of the clamping seat. A positioning plate is fixedly connected to the top of the outer surface of the guide post. The bottom of the outer surface of the positioning plate is in contact with the top of the outer surface of the moving rod. The outer surface of the positioning plate is fixedly connected to the top of the outer surface of the clamping seat by bolts.

[0010] As a further description of the above technical solution:

[0011] A rubber pad is fixedly connected to the front end of the outer surface of the contact, and the contact is provided with multiple sets.

[0022] This utility model has the following beneficial effects:

[0023] In this utility model, by designing a flip cover that can be unscrewed and a limit cover that can be lifted, operators can easily open the flip cover and lift the limit cover to conveniently take out the old contact and replace it with a new contact, which greatly simplifies the contact replacement process, improves maintenance efficiency, reduces equipment downtime caused by contact replacement, and improves overall work efficiency.

[0024] 2. In this utility model, during the contact replacement process, when a new contact is installed, the limiting block of the limiting cover engages with the rear of the contact. Under the mutual restriction of the two limiting blocks, even under the action of gravity, the contact will not detach from the moving rod, ensuring the accuracy and stability of the contact installation during the replacement process, avoiding secondary operations or equipment damage caused by accidental situations such as contact falling off, and improving the reliability of the replacement operation.

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a clamping fixture mechanism for processing irregular flanges, including a base 1. A clamping seat 3 is slidably connected to the inner surface of the base 1, allowing the clamping seat 3 to move laterally along the inner surface of the base 1. A moving rod 13 is elastically connected to the top of the outer surface of the clamping seat 3 via a tension spring 10, allowing the moving rod 13 to always move laterally forward without external force. The outer surface of the moving rod 13 is slidably connected to the top of the outer surface of the clamping seat 3, allowing the moving rod 13 to move laterally along a designated position at the top of the clamping seat 3. A limit cover 7 is hinged to the outer surface of the moving rod 13, allowing the limit cover 7 to flip upward along the outer surface of the moving rod 13. A contact 6 is inserted into the inner surface of the moving rod 13. Used for direct contact with irregular flanges, the mechanism adapts to the irregular surface of the flange by moving the rod 13, achieving effective clamping of the flange. The inner surface of the limiting cover 7 is fixedly connected to the limiting block 8, which cooperates with the contact 6. After the contact 6 is installed, the limiting block 8 engages with the contact 6 to prevent the contact 6 from coming out of the moving rod 13, ensuring its stability during operation. The outer surface of the limiting block 8 engages with the inner surface of the contact 6. The top of the outer surface of the clamping seat 3 is hinged with a flip cover 5, ensuring that the contact 6 can work in coordination with the moving rod 13 when subjected to external force. The bottom of the outer surface of the flip cover 5 is in contact with the top of the outer surface of the limiting cover 7. When the flip cover 5 is closed, it further limits the limiting cover 7, preventing the limiting cover 7 from opening accidentally and ensuring the stability of the entire mechanism.

[0033] Reference Figure 1 The outer surface of the base 1 is provided with a moving component 2. The moving component 2 is used to precisely control the movement position of the clamping seat 3 on the base 1 to better adapt to non-shaped flanges of different sizes. The moving component 2 includes a threaded rod 201. The outer surface of the threaded rod 201 is rotatably connected to the inner surface of the base 1, so that the threaded rod 201 can rotate at a specified position on the inner surface of the base 1. The outer surface of the threaded rod 201 passes through the bottom of the inner surface of the clamping seat 3 and is threadedly connected. By rotating the threaded rod 201, the clamping seat 3 can be precisely controlled to move along the axial direction of the threaded rod 201 using the thread transmission principle, so as to achieve precise adjustment of the position of the clamping seat 3. A placement plate 202 is fixedly connected to the top of the outer surface of the base 1. The placement plate 202 provides a placement platform for non-shaped flanges, ensuring the stability of non-shaped flanges during the clamping process, and also making it convenient for operators to place non-shaped flanges in a suitable position.

[0034] Reference Figures 2-4The right side of the flip cover 5 is fixedly connected to the top of the outer surface of the clamping seat 3 by bolts, so that when the flip cover 5 is closed, the bolts can keep the flip cover 5 in a closed state. The top of the outer surface of the clamping seat 3 is slidably connected to a guide post 11, which provides guidance for the movement of the positioning plate 4, ensuring the stability of the positioning plate 4 during up and down movement and preventing deviation. The top of the outer surface of the guide post 11 is fixedly connected to the positioning plate 4, which is used to limit and position the moving rod 13. By adjusting the position of the positioning plate 4, the movement range of the moving rod 13 can be controlled, thereby adjusting the position of the contact 6. The outer surface of the positioning plate 4... The bottom of the positioning plate 4 contacts the top of the outer surface of the moving rod 13. After the position of the positioning plate 4 is determined, it restricts the further movement of the moving rod 13 by contacting it, so that the contact 6 is kept in the set position. The outer surface of the positioning plate 4 is fixedly connected to the top of the outer surface of the clamping seat 3 by bolts, which ensures the stability of the positioning plate 4 after it is adjusted to a suitable position and prevents it from being displaced during operation. The bottom of the outer surface of the positioning plate 4 is provided with damping grooves 12. The damping grooves 12 increase the friction between the positioning plate 4 and the moving rod 13. When the moving rod 13 is squeezed by external force, the damping grooves 12 can better restrict the movement of the moving rod 13 and ensure the accuracy of the position of the contact 6.

[0035] Reference Figures 1-3 One end of the tension spring 10 is fixedly connected to the bottom of the outer surface of the clamping seat 3, and the other end of the tension spring 10 is fixedly connected to the rear of the outer surface of the moving rod 13. This allows the spring to apply an elastic tension to the moving rod 13, keeping it in its initial position when no external force is applied, while also allowing it to move flexibly when subjected to external force. The clamping seat 3 has four sets, which clamp the irregular flange from different directions, better adapting to the shape of the irregular flange and providing a more stable clamping force. A rubber pad 9 is fixedly connected to the front end of the outer surface of the contact 6. The rubber pad 9 increases the friction between the contact 6 and the surface of the irregular flange, preventing the irregular flange from sliding during clamping and protecting the surface of the irregular flange from scratches. Multiple sets of contacts 6 can more precisely conform to the irregular surface of the irregular flange, improving the stability and adaptability of the clamping. The bottom of the clamping seat 3 is T-shaped. The bottom of the clamping seat 3 fits into the inner surface of the base 1, which can ensure the smooth sliding of the clamping seat 3 on the base 1 and prevent the clamping seat 3 from detaching during movement. The outer surface of the threaded rod 201 is fixedly connected to a rotating handle, which allows the operator to manually rotate the threaded rod 201 and improves the convenience of operation.

[0036] Working principle: When using the device, first place the irregular flange on the placement plate 202, then rotate the four sets of threaded rods 201 in sequence, so that they drive the four sets of clamping seats 3 to move closer to the irregular flange. When the clamping seats 3 move closer to the irregular flange, the contacts 6 on the clamping seats 3 will move backward due to the pressure of the irregular flange surface. When all the contacts 6 on the clamping seats 3 form the shape of one side of the irregular flange, tighten the bolts on the positioning plate 4, so that the moving rod 13 at the rear end of the contact 6 is squeezed and limited by the damping groove on the positioning plate 4, so that the multiple sets of contacts 6 always maintain the specified shape, thereby adapting to the irregular shape of the irregular flange and fixing the irregular flange stably in the specified position.

[0037] When it is necessary to replace the contact 6, first unscrew the bolts fixing the flip cover 5, then lift the flip cover 5 to find the contact 6 that needs to be replaced, then lift the upper limit cover 7 of the moving rod 13 that fixes the contact 6, then remove the contact 6 that needs to be replaced, and then engage the rear part of the new contact 6 with the limiting block 8 inside the moving rod 13. Then flip the limiting cover 7 downward so that the limiting block 8 on the limiting cover 7 engages with the rear part of the contact 6. Under the mutual restriction of the two limiting blocks 8, the contact 6 can drive the moving rod 13 to move laterally when it comes into contact with the surface of the non-shaped flange. Then flip the flip cover 5 downward and fix it with bolts at the same time so that the flip cover 5 limits the limiting cover 7, and completely restricts and fixes the contact 6 inside the moving rod 13.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
