Description

Technical Field

[0001] This utility model relates to the field of rotary joint processing technology, specifically a rotary joint processing positioning fixture. Background Technology

[0002] A rotary joint is a connecting and sealing device that transports fluid media from a stationary pipeline to a rotating or reciprocating device, thereby providing a heating or cooling medium for the rotating mechanism. During the manufacturing process, rotary joints require positioning fixtures to clamp and position them to ensure machining accuracy.

[0003] According to Chinese Patent Publication No. CN216263925U, a positioning fixture for machining rotary joint components is disclosed. This fixture uses adjusting bolts to bring clamping blocks closer together to clamp the bent joint. After clamping, the axis of the threaded hole to be machined on the end face of the bent joint is coaxial with the axis of the connecting disc. Then, the lathe is turned on to drive the connecting disc to rotate at high speed, and the thread is machined by a tapping tool. After machining, the adjusting bolts are loosened, and the rotary joint component is removed. This positioning fixture enables rapid and precise positioning of the rotary joint component, effectively improving machining efficiency. However, this technical solution uses two separate adjusting bolts to adjust the positions of the clamping blocks on both sides of the rotary joint to achieve clamping. This can lead to inconsistent movement distances of the two clamping blocks during manual adjustment and rotation, causing a shift in the clamping and positioning position of the rotary joint, thus affecting the machining accuracy of the rotary joint. Therefore, we propose a positioning fixture for machining rotary joints. Utility Model Content

[0004] The purpose of this invention is to provide a rotary joint machining and positioning fixture, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary joint processing and positioning fixture, comprising a base plate, a screw rod II threadedly connected to a threaded hole in the base plate, a support plate rotatably connected to the top end of the screw rod II via a bearing seat, a knob II fixedly installed at the bottom end of the screw rod II, the support plate being limitedly connected to the base plate, a fixing frame fixedly installed at the top end of the base plate, fixing plates fixedly installed on both sides of the inner wall of the fixing frame, a cylinder fixedly installed at the top end of the fixing frame, a connecting frame fixedly installed at the output end of the cylinder, a clamping plate I and a clamping plate II slidably connected to the top ends of the two fixing plates respectively, a hinge seat I and a hinge seat II fixedly installed on one side of the clamping plate I and the clamping plate II respectively, a connecting rod I and a connecting rod II hinged to both ends of the connecting frame respectively, and the connecting frame being slidably connected to the inner wall of the fixing frame.

[0006] Preferably, a T-shaped sliding plate is fixedly installed at the bottom of both clamping plate one and clamping plate two, and a T-shaped sliding groove is opened at the top of both fixed plates. The T-shaped sliding plate and the T-shaped sliding groove are slidably connected. By setting the T-shaped sliding plate and the T-shaped sliding groove, clamping plate one and clamping plate two can be limited, so that clamping plate one and clamping plate two can be fixedly slid on the fixed plate.

[0007] Preferably, limiting slide plates are fixedly installed on both sides of the connecting frame, and limiting slide grooves are opened on both sides of the inner wall of the fixing frame. The limiting slide plates and limiting slide grooves are slidably connected. By setting the limiting slide plates and limiting slide grooves, the connecting frame can be limited, ensuring the stability of the connecting frame during use.

[0008] Preferably, an anti-slip pad is fixedly installed on the top of the support plate. By setting the anti-slip pad, the friction between the rotary joint and the support plate can be increased, and the sealing between the rotary joint and the support plate can be improved.

[0009] Preferably, the top of the support plate is connected to the anti-slip pad and has an adsorption groove. The inner wall of the adsorption groove has a piston cavity. A screw is threadedly connected to a threaded hole in the inner wall of the piston cavity and the outer wall of the support plate. A piston pad is fixedly installed at one end of the screw and the piston pad is slidably connected to the inner wall of the piston cavity. A knob is fixedly installed at the other end of the screw.

[0010] Preferably, a limiting rod is fixedly installed at the bottom of the support plate, and a rod hole is opened on the base plate. The limiting rod moves through the rod hole. By setting the limiting rod, the support plate can be limited to prevent it from rotating with the screw, thus ensuring the stability of the support plate during use.

[0011] This utility model provides a positioning fixture for machining rotary joints. This positioning fixture for machining rotary joints has the following advantages:

[0012] (1) The rotary joint machining positioning fixture can make clamping plate one and clamping plate two approach each other at the same time, which greatly improves the clamping positioning accuracy of the rotary joint, thereby ensuring the machining accuracy of the rotary joint. It solves the problem in the existing technical solution that the position of the clamping blocks on both sides of the rotary joint is adjusted by two separate adjusting bolts to achieve the clamping of the rotary joint. This results in the two clamping blocks moving different distances during the manual adjustment and rotation process, which causes the clamping positioning position of the rotary joint to shift, thus affecting the machining accuracy of the rotary joint.

[0013] (2) The rotary joint machining positioning fixture can generate negative pressure in the adsorption tank, so that the adsorption tank can firmly adsorb one end of the rotary joint onto the support plate, thereby greatly improving the stability of the rotary joint during fixed machining and further ensuring the machining accuracy of the rotary joint. It has a simple structure and strong practicality. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1:

[0025] A preferred embodiment of the rotary joint machining and positioning fixture provided by this utility model is, for example... Figures 1 to 6 As shown: A rotary joint processing and positioning fixture includes a base plate 1. A screw 23 is threadedly connected to a threaded hole in the base plate 1. A support plate 16 is rotatably connected to the top of the screw 23 via a bearing seat. A knob 26 is fixedly installed at the bottom of the screw 23. The support plate 16 is limitedly connected to the base plate 1. A fixing frame 2 is fixedly installed at the top of the base plate 1. Fixing plates 10 are fixedly installed on both sides of the inner wall of the fixing frame 2. A cylinder 4 is fixedly installed at the top of the fixing frame 2. A connecting frame 5 is fixedly installed at the output end of the cylinder 4. Clamping plates 6 and 7 are slidably connected to the top of the two fixing plates 10 respectively. Hinges 14 and 9 are fixedly installed on one side of clamping plates 6 and 7 respectively. Connecting rods 13 and 8 are hinged between hinges 14 and 9 and the two ends of the connecting frame 5 respectively. The connecting frame 5 is slidably connected to the inner wall of the fixing frame 2.

[0026] Specifically, in the above technical solution, when using the rotary joint machining and positioning fixture, the rotary joint is placed on the support plate 16, and then the knob 26 is rotated. The knob 26 drives the screw 23 to rotate, and the screw 23 drives the support plate 16 to move upward, thereby causing the support plate 16 to move the rotary joint upward. This allows the clamping height of the rotary joint to be adjusted according to its specifications. Then, the cylinder 4 can be activated, causing the cylinder 4 to drive the connecting frame 5 to move downward. The connecting frame 5 drives one end of the connecting rod 13 and one end of the connecting rod 8 to move downward, causing the connecting rod 13 and the connecting rod 8 to rotate simultaneously. The connecting rod 13 and the connecting rod 8 respectively drive the clamping plate 6 through the hinge seat 14 and the hinge seat 29. Simultaneously moving with clamping plate 7, clamping plate 6 and clamping plate 7 move closer to each other, ultimately clamping the rotary joint. This structure allows clamping plates 6 and 7 to move closer to each other simultaneously, significantly improving the clamping and positioning accuracy of the rotary joint. This ensures the precision of the rotary joint's machining and solves the problem in existing technologies where clamping is achieved by adjusting the positions of the clamping blocks on both sides of the rotary joint using two separate adjusting bolts. This results in inconsistent movement of the two clamping blocks during manual adjustment, causing a shift in the clamping and positioning position of the rotary joint and affecting its machining accuracy.

[0027] Furthermore, T-shaped sliding plates 15 are fixedly installed at the bottom of both clamping plate 1 6 and clamping plate 2 7, and T-shaped sliding grooves 3 are opened at the top of both fixing plates 10, and the T-shaped sliding plates 15 are slidably connected to the T-shaped sliding grooves 3.

[0028] By setting the T-shaped sliding plate 15 and the T-shaped sliding groove 3, the clamping plate 6 and the clamping plate 7 can be limited, so that the clamping plate 6 and the clamping plate 7 can be fixed and slid on the fixed plate 10.

[0029] Furthermore, limiting slide plates 11 are fixedly installed on both sides of the connecting frame 5, and limiting slide grooves 12 are opened on both sides of the inner wall of the fixing frame 2, and the limiting slide plates 11 and the limiting slide grooves 12 are slidably connected.

[0030] The limiting slide plate 11 and the limiting slide groove 12 can limit the connection frame 5 and ensure the stability of the connection frame 5 during use.

[0031] Furthermore, an anti-slip pad 17 is fixedly installed on the top of the support plate 16;

[0032] By setting anti-slip pads, the friction between the rotary joint and the support plate 16 can be increased, and the sealing between the rotary joint and the support plate 16 can be improved.

[0033] Furthermore, a limiting rod 24 is fixedly installed at the bottom of the support plate 16, and a rod hole 25 is opened on the base plate 1, through which the limiting rod 24 moves.

[0034] The limiting rod 24 can limit the support plate 16, preventing it from rotating with the screw 23 and ensuring its stability during use.

[0035] Example 2:

[0036] Based on Embodiment 1, a preferred embodiment of the rotary joint machining and positioning fixture provided by this utility model is, for example... Figures 1 to 6 As shown: The top of the support plate 16 is connected to the anti-slip pad 17 and has an adsorption groove 18. The inner wall of the adsorption groove 18 has a piston cavity 19. The inner wall of the piston cavity 19 is connected to the outer wall of the support plate 16 through a threaded hole. A screw 21 is threadedly connected to the inner wall of the piston cavity 19 and the outer wall of the support plate 16. A piston pad 20 is fixedly installed at one end of the screw 21. The piston pad 20 is slidably connected to the inner wall of the piston cavity 19. A knob 22 is fixedly installed at the other end of the screw 21.

[0037] Specifically, in the above technical solution, when the rotary joint is placed on the support plate 16, the knob 22 can be rotated. The knob 22 drives the screw 21 to rotate, and the screw 21 drives the piston pad 20 to contract into the piston cavity 19, thereby generating a negative pressure in the adsorption tank 18. This allows the adsorption tank 18 to firmly adsorb one end of the rotary joint onto the support plate 16, thereby greatly improving the stability of the rotary joint during fixed processing and further ensuring the processing accuracy of the rotary joint. The structure is simple and highly practical.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
