Description

Technical Field

[0001] This utility model relates to the field of post-processing technology of mechanical processing, and in particular to a positioning fixture for processing communication tube shell devices. Background Technology

[0002] Communication tube housings generally consist of a tube and a ring formed on the outer circumference of the tube. They are manufactured through machining. After machining, multiple machining grooves and burrs are commonly formed on the inner wall. These unavoidable machining defects can affect the use of such products. During use, these burrs can damage cables. Conventionally, after machining, defective products are manually inspected to pick out defective products. Products with burrs are post-processed using scrapers. In the post-processing process, such workpieces are usually placed on a tool with holes and inserted into the holes before processing. However, when using holes for positioning, the workpiece is prone to movement, which affects the processing effect on the inner wall of the product. Utility Model Content

[0003] This utility model provides a positioning fixture for processing communication tube shell devices, which overcomes the shortcomings of the prior art and solves the problem of inconvenient positioning of tube shell workpieces in post-processing, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A positioning fixture for processing communication tube housing devices includes a base with four support arms mounted on it. Mounting seats are bolted to the upper ends of the support arms. A concave seat is welded to the inner end of the mounting seat. A hinge shaft is rotatably mounted on the inner end of the concave seat. A constraint outer plate is mounted on the hinge shaft. A downward pressing protrusion is mounted on the upper end of the constraint outer plate. An outward pushing plate is formed at the lower end of the constraint outer plate. An inclined surface is formed on the inner wall of the outward pushing plate, with the lower end of the inclined surface extending inward. The rotatably mounted constraint outer plate, outward pushing plate, and downward pressing protrusion, when the outward pushing plate rotates outward around the hinge shaft, will cause the constraint outer plate and downward pressing protrusion at its upper end to rotate inward. The constraint outer plate will act on the outer circumference of the ring, while the lower wall of the downward pressing protrusion will act on the upper end of the ring, thereby achieving the purpose of fixing such tube housings.

[0006] In order to enable the multiple push plates mentioned above to rotate outwards simultaneously, thereby improving the product fixation effect, a limit seat is bolted to the support arm. A vertical rod is inserted through the limit seat, and a base is provided at the upper end of the vertical rod. The outer periphery of the base acts on the inclined plane, and a spring is sleeved on the vertical rod. The spring is located between the base and the limit seat. When the base moves downwards, it will cause the push member to rotate outwards, thereby achieving the purpose of fixing the product.

[0007] In order to ensure that the outer push plate is inward before clamping and the outer plate is constrained to be in an outward posture, a vertical hole is provided on the support arm. The lower end of the outer push plate is connected to a through rod by a thread. The through rod passes through the vertical hole and an outer pressure head is sleeved on the through rod. The outer end of the outer pressure head acts on the inner wall of the support arm. An inner top spring is sleeved on the through rod. The inner top spring is located between the outer pressure head and the outer push plate. The inner top spring can make the outer push plate inward when there is no force inside it. The through rod can prevent the inner top spring from deforming or escaping.

[0008] Furthermore, the inner wall of the outer constrained plate is formed with a concave arc groove to improve the positioning effect of the ring.

[0009] Furthermore, the inner wall of the push plate is formed with a concave arc surface, which matches the outer circumferential arc surface of the chassis, so that the push plate can rotate outward when the chassis moves downward.

[0010] Furthermore, to facilitate product disassembly, the lower wall of the pressure plate is designed as an inclined surface, with the inner end of the inclined surface extending upwards. A vertically positioned limiting screw is threaded onto the pressure plate. When releasing the clamp, the limiting screw is first loosened, thereby releasing the force exerted by the limiting screw on the upper end of the ring. During this process, the product will move upwards under the action of the spring. As it moves upwards, its force on the outer push plate gradually decreases, causing the outer push plate to rotate inwards under the action of the inner top spring, thus releasing the limiting force of the pressure plate on the upper end of the ring.

[0011] Furthermore, the outer periphery of the chassis is tapered, and the lower end of the outer periphery of the chassis is the smaller end. This structural design can improve the flexibility of the chassis when it moves.

[0012] Furthermore, the outer end of the external pressure head has a hemispherical structure to reduce the contact friction between the external pressure head and the inner wall of the support arm.

[0013] Furthermore, a pair of symmetrical support arms have oblong holes at their lower ends, through which guide screws are inserted. The outer end of the guide screw is connected to an outer plate via a thread, and the inner end of the guide screw is connected to a lower pressure plate via a thread. The lower pressure plate is installed on the lower end of the vertical rod via screws. A hinge screw is connected to the support arm via a thread, and a lower push plate is rotatably mounted on the hinge screw. The lower end of the lower push plate acts on the upper wall of the outer plate, and a holding rod is welded to the upper end of the lower push plate. Components such as the lower push plate are provided to ensure the stability of the product when it is fixed.

[0014] Furthermore, the lower end of the push plate has an arc-shaped structure to facilitate the rotation of the push plate.

[0015] The advantages of the above technical solution are:

[0016] This invention facilitates the positioning and fixing of communication tube shell-type workpieces and improves the stability after fixing, thus enabling post-processing operations on such products. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0018] Figure 1 A three-dimensional structural diagram of one embodiment is shown.

[0019] Figure 2 A magnified view of point A is shown.

[0020] Figure 3 A magnified view of point B is shown. Detailed Implementation

[0021] like Figures 1-3 As shown, a positioning fixture for processing communication tube housing devices includes a base 1, on which four support arms 2 are mounted. The upper end of each support arm 2 is bolted to a mounting seat 3. A concave seat 30 is welded to the inner end of the mounting seat 3. A hinge shaft 31 is rotatably provided on the inner end of the concave seat 30. A constraint outer plate 32 is provided on the hinge shaft 31. The inner wall of the constraint outer plate 32 is formed with an inward concave arc groove. A downward pressing protrusion 33 is provided at the upper end of the constraint outer plate 32. An outward push plate 34 is formed at the lower end of the constraint outer plate 32. The inner wall of the outward push plate 34 is formed with an inward concave arc surface and an inclined surface. The lower end of the inclined surface extends inward at an inward angle.

[0022] A limiting seat 4 is bolted onto the support arm 2. A vertical rod 40 is threaded through the limiting seat 4. A base 41 is provided at the upper end of the vertical rod 40. The outer periphery of the base 41 is conical, and the lower end of the outer periphery of the base 41 is the smaller end. The outer periphery of the base 41 acts on the inclined surface. A spring 42 is sleeved on the vertical rod 40. The spring 42 is located between the base 41 and the limiting seat 4.

[0023] The support arm 2 has a vertical hole 350. The lower end of the outer push plate 34 is connected to a through rod 35 by a thread. The through rod 35 passes through the vertical hole 350. An outer pressure head 37 is sleeved on the through rod 35. The outer end of the outer pressure head 37 has a hemispherical structure. The outer end of the outer pressure head 37 acts on the inner wall of the support arm 2. An inner top spring 36 is sleeved on the through rod 35. The inner top spring 36 is located between the outer pressure head 37 and the outer push plate 34.

[0024] Before operation, the outer constraint plate 32 is in an outward-opening state, the inner top spring 36 is in a naturally extended state, the spring 42 is also in a naturally extended state, and the chassis 41 is located at a high position.

[0025] During the fixing process, the operator places the product on the chassis 41 and presses down on the pipe fitting 9 so that the ring 90 on the pipe fitting 9 is below the lower pressing plate 33. As the pipe fitting 9 and the chassis 41 move downward, the spring 42 is compressed. During the movement, the outer periphery of the chassis 41 acts on the inner wall of the outer push plate 34, causing the outer push plate 34 to rotate outward. During this process, the inner spring 36 is compressed until the ring 90 is below the lower pressing plate 33. Then, the pressure on the pipe fitting 9 is released, and the pipe fitting 9 moves upward a short distance under the action of the spring 42, so that the upper end of the ring 90 rests against the lower wall of the lower pressing plate 33. At this time, the outer plate 32 is in a vertical state, and then the inner wall of the pipe fitting 9 is processed.

[0026] In some embodiments, the lower wall of the pressing protrusion 33 is an inclined surface, the inner end of the inclined surface extends upward at an incline, and a vertically arranged limiting screw is threaded onto the pressing protrusion 33.

[0027] In this embodiment, during clamping, after the tube 9 is pushed down, the limiting screw needs to be tightened so that the lower end of the limiting screw acts on the upper end of the ring 90, thereby fixing the tube 9. If the limiting screw is removed after processing, the tube 9 will move upward a certain distance under the action of the spring 42, and during the movement, the lower pressing protrusion 33 will rotate outward at a certain angle, after which the product can be removed.

[0028] In some embodiments, a pair of symmetrical support arms 2 have a waist-shaped hole 45 at their lower ends, a guide screw 44 passes through the waist-shaped hole 45, an outer plate 440 is threaded to the outer end of the guide screw 44, a pressure plate 43 is threaded to the inner end of the guide screw 44, the pressure plate 43 is screwed to the lower end of the vertical rod 40, a hinge screw 46 is threaded to the support arm 2, a push plate 47 is rotatably mounted on the hinge screw 46, the lower end of the push plate 47 has an arc-shaped structure, the lower end of the push plate 47 acts on the upper wall of the outer plate 440, and a gripping rod 48 is welded to the upper end of the push plate 47.

[0029] In this embodiment, when positioning the pipe fitting 9, when the lower pressing plate 33 limits the upper end of the ring 90, the operator rotates the lower pushing plate 47 to lock the height of the lower pressing plate 43 and the chassis 41 through the lower pushing plate 47, and then performs the pipe fitting processing operation.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
