Description

Technical Field

[0001] This utility model relates to the field of wire thread sleeve processing technology, and in particular to a positioning tool for metal thread sleeve processing. Background Technology

[0002] Wire thread inserts are a new type of internal thread fastener. They are spring-shaped, concentric bodies with internal and external threads, precisely machined from high-precision, high-strength, and smooth-surfaced cold-rolled diamond-shaped stainless steel wire.

[0003] Announcement No. CN220145651U discloses a positioning fixture for a grinding mandrel in the production of wire thread inserts. The fixture allows adjustment of the positioning component's position on the horizontal X-axis by moving a sliding block within a groove. A lifting sleeve allows adjustment of the positioning component's position on the vertical Y-axis. A rotating head allows rotation of the positioning component, enabling angular adjustment. This convenient positioning and adjustment meets the needs of different positions and angles during grinding, effectively reducing labor intensity. Simultaneously, clamping wheels fix the mandrel, and three-point positioning securely fixes the mandrel inside the housing. The clamping wheels are covered with a rubber layer for effective anti-slip, improving clamping stability and preventing damage to the mandrel. Adjusting the position of the adjusting screw on the housing allows for fixing mandrels of different sizes, demonstrating strong versatility.

[0004] However, during the use of this device, the wire thread insert is fixed by rotating three clamping wheels in sequence. Without simultaneously pushing the three clamping wheels, the wire thread insert is not positioned at the center of the device, leading to deviations during grinding and affecting its subsequent use. Therefore, a positioning fixture for metal thread insert processing is proposed to solve this problem. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a positioning tool for processing metal threaded sleeves, which can solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for processing metal threaded sleeves, comprising a fixed shell, a base plate fixedly connected to the surface of the fixed shell, a guide groove formed on the surface of the base plate, two sliding blocks provided on the surface of the base plate, one of the two sliding blocks being fixedly connected to the base plate, and the other sliding block being slidably connected to the inner wall of the guide groove, the two sliding blocks having the same surface structure, a lifting sleeve fixedly connected to the surface of the sliding block, a fixed sleeve fixedly connected to the surface of the lifting sleeve, a rotating tube rotatably connected inside the fixed sleeve, a sliding sleeve provided inside the rotating tube, a circumferentially arranged sliding rod slidably connected inside the sliding sleeve, a clamping wheel fixedly connected to one end of the sliding rod located inside the sliding sleeve, a threaded rod threadedly connected inside the rotating tube, the threaded rod penetrating into the interior of the rotating tube, and the surface of the threaded rod rotatably connected to the interior of the sliding sleeve.

[0007] Preferably, the interior of the rotating tube is tapered, and the sliding rod is in contact with the interior of the rotating tube.

[0008] Preferably, a fixing rod is fixedly connected to the outside of the rotating tube, and a rubber sleeve is provided on the surface of the fixing rod.

[0009] Preferably, the surface of the rotating tube is provided with a rubber pad, and the rubber pad is in contact with the fixed sleeve.

[0010] Preferably, an electric push rod is fixedly connected to one side of the base plate, the output end surface of the electric push rod is slidably connected to the inside of the base plate, and the output end of the electric push rod is fixedly connected to a sliding block.

[0011] Preferably, the inner wall of the guide groove is provided with a limiting groove, and the surface of the sliding block is fixedly connected with a limiting block, the surface of the limiting block sliding with respect to the inner wall of the limiting groove.

[0012] Preferably, the surface of the fixing shell is provided with a groove, the inner wall of the groove is inclined, and the surface of the base plate is also inclined.

[0013] Preferably, a return spring is movably sleeved on the surface of the sliding rod, and the two ends of the return spring are fixedly connected to the clamping wheel and the sliding sleeve, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The positioning fixture for machining the metal threaded sleeve rotates the threaded rod, causing the sliding sleeve to move the sliding rod. The sliding rod then contacts the inside of the rotating tube, and the sliding rod is forced to push the clamping wheel, thus clamping and fixing the wire threaded sleeve. This simultaneously drives the three clamping wheels to move, thus fixing the wire threaded sleeve. The wire threaded sleeve can be fixed in the center position of the three clamping wheels, avoiding the operation in the comparative case where the three clamping wheels were adjusted in turn and the wire threaded sleeve could not be fixed in the center position. This also avoids the situation where the wire threaded sleeve is not in the center position during the rotation machining of the wire threaded sleeve, which causes the grinding deviation. This improves the grinding effect of the device. Attached Figure Description

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a positioning fixture for processing metal threaded sleeves, including a fixed shell 1, a base plate 8 fixedly connected to the surface of the fixed shell 1, a guide groove 9 formed on the surface of the base plate 8, and two sliding blocks 11 disposed on the surface of the base plate 8. One sliding block 11 is fixedly connected to the base plate 8, and the other sliding block 11 is slidably connected to the inner wall of the guide groove 9. The two sliding blocks 11 have the same surface structure. A lifting sleeve 3 is fixedly connected to the surface of the sliding block 11, and a fixed sleeve 4 is fixedly connected to the surface of the lifting sleeve 3. A rotating tube 5 is rotatably connected inside the fixed sleeve 4. The interior of the rotating tube 5 is conical and has a sliding... The sliding sleeve 12 has a sliding rod 13 arranged in a circle inside. The sliding rod 13 is in contact with the inside of the rotating tube 5. A clamping wheel 15 is fixedly connected to one end of the sliding rod 13 inside the sliding sleeve 12. Due to the conical shape inside the rotating tube 5, when the sliding sleeve 12 moves, the sliding rod 13 will contact the inside of the rotating tube 5, so that the sliding rod 13 is subjected to force and slides into the sliding sleeve 12, thereby causing the clamping wheel 15 to move and complete the clamping of the wire thread sleeve. The rotating tube 5 has a threaded rod 6 inside, which penetrates into the inside of the rotating tube 5. The surface of the threaded rod 6 is rotatably connected to the inside of the sliding sleeve 12.

[0024] A fixing rod 7 is fixedly connected to the outside of the rotating tube 5. The surface of the fixing rod 7 is provided with a non-slip rubber sleeve, which makes it easy to rotate the rotating tube 5 to change the angle of clamping the item.

[0025] A rubber pad is provided on the surface of the rotating tube 5. The rubber pad is in contact with the fixed sleeve 4. By providing the rubber pad, the space between the fixed sleeve 4 and the rotating tube 5 is filled, which increases the friction between the fixed sleeve 4 and the rotating tube 5, thereby limiting the position where the rotating tube 5 stops.

[0026] An electric push rod 10 is fixedly connected to one side of the base plate 8. The output end surface of the electric push rod 10 is slidably connected to the inside of the base plate 8, and the output end of the electric push rod 10 is fixedly connected to the sliding block 11.

[0027] The inner wall of the guide groove 9 is provided with a limiting groove 16. The surface of the sliding block 11 is fixedly connected with a limiting block 17. The surface of the limiting block 17 slides against the inner wall of the limiting groove 16. The surface of the fixed shell 1 is provided with a groove 2. The inner wall of the groove 2 is inclined. The surface of the base plate 8 is also inclined. Due to the inclined surface of the base plate 8, the grinding debris falls through the inclined surface of the base plate 8 and enters the interior of the fixed shell 1 through the groove 2 for collection. Since the guide groove 9 is a through groove, some debris will directly pass through the guide groove 9 and enter the inner wall of the fixed shell 1.

[0028] A return spring 14 is movably sleeved on the surface of the sliding rod 13. The two ends of the return spring 14 are fixedly connected to the clamping wheel 15 and the sliding sleeve 12, respectively. When the sliding rod 13 moves into the sliding sleeve 12, the return spring 14 is in a stretched state.

[0029] Working principle: When it is necessary to clamp and fix the wire thread insert, the operator inserts the wire thread insert into the sliding sleeve 12, and then rotates the threaded rod 6. The threaded rod 6 moves into the rotating tube 5, and pushes the sliding sleeve 12. The movement of the sliding sleeve 12 causes the sliding rod 13 to contact the inner wall of the rotating tube 5. The sliding rod 13 is then forced to move into the sliding sleeve 12. The sliding rod 13 pushes the clamping wheel 15, causing the clamping wheel 15 to move and clamp and fix the wire thread insert.

[0030] After one side of the wire thread insert is fixed, the electric push rod 10 is activated. The output end of the electric push rod 10 pushes the sliding block 11 to slide. The sliding block 11 then moves the fixed wire thread insert toward the fixed sliding block 11, thereby rotating the threaded rod 6 on the fixed sliding block 11. This completes the fixing of the other end of the wire thread insert, thus avoiding the situation where only one end of the wire thread insert is fixed during rotation and grinding, resulting in the other end of the wire thread insert being suspended and vibrating during rotation. This further improves the grinding effect. At the same time, the guide groove 9 extends through to the inside of the fixed shell 1, preventing the debris generated during grinding from getting stuck inside the guide groove 9 and affecting the fixing of both ends of the wire thread insert, further reducing the usage limitations of the device.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
