Description

Technical Field

[0001] The utility model relates to a screw sleeve, in particular to a die base clamp based on an internal and external threaded sleeve, belonging to the technical field of die base clamps for internal and external threaded sleeves. Background Art

[0002] The threaded sleeve is a new type of internal thread fastener, suitable for threaded connection. It is screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread, and the bolt (or screw) is then screwed into it. It is also called a threaded sleeve, or simply a threaded sleeve. It is a spring-shaped internal and external threaded concentric body made of high-strength, high-precision, smooth-surfaced cold-rolled diamond stainless steel wire, and is mainly used to enhance and protect the internal threads of low-strength materials. The principle is to form an elastic connection between the screw and the internal thread of the base, eliminate thread manufacturing errors, and improve the connection strength. The wire thread sleeve is embedded in the threaded hole of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, fiberglass, and plastic, and can form high-precision internal threads that meet international standards. It has the functions of high connection strength, earthquake resistance, impact resistance, and wear resistance, and can disperse stress to protect the base thread, greatly extending the service life of the base, and is widely used in electronic applications;

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figure 1-4 As shown, an embodiment of the utility model provides a workbench 1, a mold base body 4 is arranged at the middle end of the top of the workbench 1, support rods 5 are fixedly installed on all sides of the bottom of the workbench 1, a mounting plate 6 is fixedly installed on the outer surface of the support rod 5, a cylinder 7 is fixedly installed on the bottom of the mounting plate 6, a circular plate 8 is fixedly installed on the top of the cylinder 7, a discharging mechanism 2 is arranged on the top of the circular plate 8, the discharging mechanism 2 includes a vertical rod 201, a clamping mechanism 3 is arranged on the top of the circular plate 8, and the clamping mechanism 3 includes a mounting rod 301.

[0027] By setting up the discharging mechanism 2, the threaded sleeve can be automatically discharged after processing, which saves the time of the operator to take out the threaded sleeve when a large number of threaded sleeves need to be processed, saves labor costs, and improves the efficiency of threaded sleeve processing. By setting up the clamping mechanism 3, the mold base body 4 can be fixed, avoiding the situation that when the threaded sleeve is processed by the mold base body 4, the mold base body 4 is offset, and then the processing position of the threaded sleeve is offset, the threaded sleeve cannot meet the basic requirements of production and processing, resulting in waste of materials.

[0028] Example 2

[0029] In one embodiment, the vertical rods 201 are fixedly installed on the left and right sides of the top of the circular plate 8, and a tooth plate 202 is fixedly installed on the top of the vertical rod 201. A box 203 is fixedly installed on the bottom of the workbench 1. The inner sides of the left and right sides of the box 203 are movably connected with gears 204. A connecting plate 205 is provided in the inner cavity of the box 203. A connecting rod 207 is fixedly installed on the top of the connecting plate 205. A push plate 208 is fixedly installed on the top of the connecting rod 207. A displacement groove 211 is provided at the bottom of the workbench 1, and the push plate 208 is movably connected to the inner cavity of the displacement groove 211. Tooth blocks 206 are fixedly installed on the left and right sides of the connecting plate 205, and the outer side of the tooth block 206 is meshed with the inner side of the gear 204.

[0030] By setting the displacement groove 211 and the push plate 208, the screw sleeve being processed in the die base body 4 can be automatically discharged, which saves the time for the operator to repeatedly take the screw sleeve out of the die base body 4, and improves work efficiency. By setting the tooth block 206, the connecting plate 205 can maintain left-right balance when moving up and down, avoiding the situation where the connecting plate 205 is offset when moving, and then the push plate 208 cannot automatically discharge the screw sleeve in the die base body 4. By setting the limit block 210 and the limit groove 209, the connecting plate 205 can be limited when moving up and down, avoiding the situation where it is offset when moving.

[0031] Example 3

[0032] In one embodiment, the mounting rod 301 is fixedly mounted around the top of the circular plate 8, a push block 302 is fixedly mounted on the top of the mounting rod 301, movable grooves 303 are opened on the left and right sides and the front and rear sides of the top of the workbench 1, a sliding rod 304 is fixedly connected in the inner cavity of the movable groove 303, a slider 305 is movably connected to the outer surface of the sliding rod 304, a hard spring 306 is fixedly mounted on the outer side of the slider 305, the outer side of the hard spring 306 is fixedly connected to the outer side of the inner cavity of the movable groove 303, a fixing rod 307 is fixedly mounted on the top of the slider 305, a splint 308 is fixedly mounted on the top of the fixing rod 307, a protective pad 311 is bonded to the inner side of the splint 308 by pp glue, a sliding groove 310 is opened on the outer side of the inner cavity of the movable groove 303, a sliding block 309 is fixedly mounted on the outer side of the slider 305, and the sliding block 309 is movably connected to the inner cavity of the sliding groove 310.

[0033] By setting the slider 305, the clamping plate 308 can be fitted to the outer side of the mold base body 4, and can clamp the mold base bodies 4 of different sizes. By setting the protective pad 311, due to its material, when the clamping plate 308 clamps the mold base body 4, it can protect the mold base body 4 and prevent the clamping plate 308 from causing scratches on the mold base body 4. By setting the sliding block 309 and the sliding groove 310, the slider 305 can be limited to prevent the slider 305 from deviating when driving the clamping plate 308 to move, thereby preventing the clamping plate 308 from being able to clamp the mold base body 4.

[0034] When the utility model is working: the cylinder 7 extends upward, and as the cylinder 7 extends, the circular plate 8 drives the mounting rod 301 and the push block 302 to move upward. Due to the movement of the push block 302, the slider 305 fitted therewith moves inward along the outer surface of the slide rod 304. The hard spring 306 is deformed due to the movement of the slider 305. The fixed rod 307 drives the clamping plate 308 and the protective pad 311 to clamp the die base body 4 through the movement of the slider 305. When the thread sleeve is processed, the cylinder 7 drives The movable circular plate 8 moves downward. Due to the disappearance of force, the hard spring 306 drives the slider 305 to move outward through its own tension. The slider 305 releases the clamping of the die base body 4. At this time, the vertical rod 201 drives the tooth plate 202 to move downward synchronously, and causes the gear 204 to rotate. When the gear 204 rotates, the connecting plate 205 pushes the connecting rod 207 and the push plate 208 upward to move. The push plate 208 pushes the processed screw sleeve out along the inner cavity of the displacement groove 211 to complete the automatic discharging work.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
