Description

Technical Field

[0002] Thread milling equipment is the core equipment for precision thread machining of metal products. It achieves high-precision, high-surface-quality, and flexible thread machining by cutting along a helical trajectory with a high-speed rotating thread milling cutter. Compared with traditional tapping and turning processes, it has significant advantages in machining difficult-to-machine materials, large-diameter threads, and thin-walled parts, and has become the mainstream choice for thread machining in the automotive, aerospace, and high-end equipment fields.

[0003] The irregular metal product is placed on the machine table, and the irregular metal product is clamped and fixed by the cooperation of various parts. The thread is then milled on the metal product by a milling cutter.

[0004] Existing thread milling devices for metal products are inadequate in their clamping function when dealing with irregular metal products, and cannot quickly clamp and fix the metal products. Changing the milling cutter requires cumbersome steps, which affects the efficiency of thread milling of metal parts. Therefore, a thread milling device for metal products is proposed.

The clamping mechanism includes a bidirectional lead screw installed inside the base through a bearing seat. A cross slider is symmetrically arranged on the outer surface of the bidirectional lead screw through a threaded sleeve. A long strip plate is installed on the top of the cross slider. Several slide rods are evenly distributed inside the long strip plate. A clamping plate is installed on the same side of every two slide rods. A locking mechanism is provided at the bottom of the multi-axis adjustment component. The locking mechanism includes a first locking plate. A second locking plate is movably mounted on one side of the first locking plate via a hinge seat. A thread-opening head is provided on the opposite side of the first locking plate and the second locking plate. Several pointed cone blocks adapted to the thread-opening head are installed on the inner surfaces of both the first locking plate and the second locking plate.

[0007] In a preferred embodiment of the thread milling device for metal products described in this utility model, the base has a T-shaped groove adapted to the cross slider, the cross slider is slidably connected inside the T-shaped groove, the elongated plate is slidably connected to the bottom of the inner cavity of the base, a telescopic plate is installed at the opening of the T-shaped groove, and a plurality of round holes adapted to the slide rod are evenly distributed on one side of the elongated plate, the slide rod is slidably connected inside the round holes.

[0008] In a preferred embodiment of the thread milling device for metal products described in this utility model, a plurality of U-shaped plates adapted to the slide rod are evenly distributed on one side of the long strip plate, a first spring is symmetrically installed on one side of the clamping plate, a first motor is installed at one end of the bidirectional lead screw extending to the outside of the base, and an auxiliary plate is provided at the center of the bidirectional lead screw.

[0009] In a preferred embodiment of the thread milling device for metal products described in this utility model, a limiting hole adapted to the slide rod is provided on one side of the U-shaped plate, the slide rod is slidably connected inside the limiting hole, the first spring is located outside the slide rod, and the auxiliary plate is installed at the center of the T-shaped slide groove.

[0012] (III) Beneficial Effects This utility model provides a thread milling device for metal products. It has the following advantages: 1. The clamping mechanism can clamp irregular metal products. When the bidirectional lead screw rotates, it drives two cross sliders to move towards each other. The cross sliders drive the corresponding long strip plates to move. With the assistance of several sliding rods, the long strip plates push the corresponding clamping plates towards each other, clamping the metal products placed on opposite sides of the two clamping plates. When the clamping plates touch the metal products, the clamping plates apply pressure to the first spring, causing it to deform. The first spring applies a reverse thrust to the clamping plates, making the clamping plates fit tightly against the surface of the metal products. Based on the extension and retraction length of the sliding rods in the U-shaped plate, irregular metal products are clamped, thus improving the adaptability of the device.

[0013] 2. Through the locking mechanism, different types of thread-cutting heads can be replaced according to different thread milling requirements. Press the pressure rod down to release the L-shaped clamping plate from the restraint of the limiting rod. Then, flip the second locking plate outward around the hinge to remove the thread-cutting head and replace it with a different thread-cutting head. Place the replaced thread-cutting head on the opposite side of the first and second locking plates. Under the action of several pointed conical blocks, the thread-cutting head is fixed. The L-shaped clamping plate is then clamped again on the outside of the limiting rod to complete the replacement of the thread-cutting head. This has the function of quickly replacing thread-cutting heads and improving the milling efficiency of metal products. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a thread milling device for metal products, comprising: Base 1, with a multi-axis adjustment component installed at the top of its inner cavity; The clamping mechanism 2 is located at the bottom of the inner cavity of the base 1. The clamping mechanism 2 includes a bidirectional lead screw 201 installed inside the base 1 through a bearing seat. A cross slider 204 is symmetrically arranged on the outer surface of the bidirectional lead screw 201 through a threaded sleeve. A long strip plate 206 is installed on the top of the cross slider 204. Several slide rods 207 are evenly distributed inside the long strip plate 206. A clamping plate 209 is installed on the same side of every two slide rods 207.

[0023] like Figure 3 As shown, in this embodiment, the base 1 has a T-shaped groove inside that is adapted to the cross slider 204. The cross slider 204 is slidably connected inside the T-shaped groove. The long strip 206 is slidably connected to the bottom of the inner cavity of the base 1. A telescopic plate is installed at the opening of the T-shaped groove. Several round holes adapted to the slide rods 207 are evenly distributed on one side of the long strip 206. The slide rods 207 are slidably connected inside the round holes. When the bidirectional lead screw 201 drives the cross slider 204 to move, when the clamping plate 209 contacts the metal product, the two slide rods 207 extend and retract in the round holes to adapt to metal products of different shapes and clamp and fix metal products of different shapes.

[0024] like Figure 2 and Figure 3As shown, in this embodiment, several U-shaped plates 205 adapted to slide bars 207 are evenly distributed on one side of the long strip plate 206. First springs 208 are symmetrically installed on one side of the clamping plate 209. One end of the bidirectional lead screw 201 extends to the outside of the base 1 and a first motor 203 is installed. An auxiliary plate 202 is provided at the center of the bidirectional lead screw 201. Under the action of the first spring 208, when the clamping plate 209 is subjected to force, the first spring 208 applies a reverse thrust to the clamping plate 209, so that the clamping plate 209 is tightly attached to the surface of the metal product. Under the action of several first springs 208, it can adapt to the clamping of irregular metal products.

[0025] like Figure 3 As shown, in this embodiment, a limiting hole adapted to the slide rod 207 is provided on one side of the U-shaped plate 205. The slide rod 207 is slidably connected inside the limiting hole. The first spring 208 is located outside the slide rod 207. The auxiliary plate 202 is installed at the center of the T-shaped slide groove. Under the action of the U-shaped plate 205, it can ensure that the slide rod 207 keeps moving horizontally when it moves. Under the action of the auxiliary plate 202, the bidirectional lead screw 201 will not bend when it is subjected to force.

[0026] Furthermore, the metal product is placed on one side of the two clamping plates 209, and the first motor 203 is controlled to run. The output end of the first motor 203 drives the bidirectional lead screw 201 to rotate. With the assistance of the auxiliary plate 202, the bidirectional lead screw 201 drives the two cross sliders 204 to move towards each other inside the base 1. The cross sliders 204 drive the corresponding long strips 206 to move. With the assistance of the slide rod 207, the long strips 206 drive the corresponding clamping plates 209 to move. After several clamping plates 209 have contacted the surface of the metal product, the clamping plates 209 on the opposite side are pushed towards each other again. At this time, the clamping plates 209 apply pressure to the first spring 208 and deform, and the first spring 208 also applies a reverse thrust to the clamping plates 209, so that the clamping plates 209 are tightly attached to the surface of the metal product. According to the different extension lengths of the slide rod 207 in the long strips 206, the irregular metal product can be clamped and fixed by the clamping plates 209.

[0027] Example 2 Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment. The locking mechanism 3 is located at the bottom of the multi-axis adjustment component. The locking mechanism 3 includes a first locking plate 302. A second locking plate 303 is movably mounted on one side of the first locking plate 302 via a hinge seat. A thread-opening head 305 is provided on the opposite side of the first locking plate 302 and the second locking plate 303. A plurality of pointed cone blocks 304 adapted to the thread-opening head 305 are installed on the inner surfaces of both the first locking plate 302 and the second locking plate 303.

[0028] like Figure 4 As shown, in this embodiment, the locking mechanism 3 further includes a second motor 301 installed at the output end of the multi-axis adjustment component, a first locking plate 302 installed at the output end of the second motor 301, a pressure rod 306 movably installed inside the first locking plate 302, and L-shaped clamping plates 307 evenly distributed on one side of the pressure rod 306. Limiting rods 308 adapted to the L-shaped clamping plates 307 are evenly distributed on the outer surface of the second locking plate 303. Under the action of the L-shaped clamping plates 307, a locking force is applied to the limiting rods 308, fixing the second locking plate 303 to one side of the first locking plate 302, fixing the threaded head 305, and also facilitating the replacement of different models of threaded heads 305.

[0029] like Figure 5 As shown, in this embodiment, the outer surface of the first locking plate 302 is provided with a square hole that is adapted to the L-shaped locking plate 307. The L-shaped locking plate 307 is slidably connected inside the square hole. A second spring 309 is installed at the bottom of the pressure rod 306. Under the action of the second spring 309, an upward pushing force is applied to the pressure rod 306, so that the L-shaped locking plate 307 is always locked on the outside of the limiting rod 308, thus fixing the second locking plate 303 to the first locking plate 302.

[0030] Furthermore, the multi-axis adjustment component operates in a conventional manner known to those skilled in the art, and its specific parameters can be selected according to actual needs. Manually pressing down the pressure rod 306 causes it to move the two L-shaped clamping plates 307, removing them from the outside of the corresponding limiting rods 308. Then, manually flipping the second locking plate 303 outwards around the hinge point, and removing the threaded end 305 from the opposite side of the second locking plate 303 and the first locking plate 302, and replacing it with a different model of threaded end... The threaded end 305 is placed on the opposite side of the first locking plate 302 and the second locking plate 303. The second locking plate 303 is attached to the first locking plate 302 around the hinge, so that several pointed cones 304 are attached to the outer surface of the threaded end 305. The thrust applied to the pressure rod 306 is removed. Under the action of the second spring 309, an upward thrust is applied to the pressure rod 306, so that the two L-shaped clamping plates 307 are clamped on the corresponding limiting rods 308, thus completing the replacement of the threaded end 305.

[0031] Working principle: The device is connected to an external power supply and controller using a wiring harness. Metal products are placed on opposite sides of two clamping plates 209. The first motor 203 is controlled to run, and its output drives the bidirectional lead screw 201 to rotate. With the assistance of the auxiliary plate 202, the bidirectional lead screw 201 drives two cross sliders 204 to move towards each other inside the base 1. The cross sliders 204 drive the corresponding elongated plates 206 to move. The elongated plates 206, with the assistance of the sliding rod 207, drive the corresponding clamping plates 209 to move. [The last sentence appears to be incomplete and possibly refers to a specific mechanism or operation.] After the holding plates 209 have all contacted the surface of the metal product, the opposite clamping plates 209 are pushed towards each other again. At this time, the clamping plates 209 apply pressure to the first spring 208 and deform, and the first spring 208 also applies a reverse thrust to the clamping plates 209, so that the clamping plates 209 are tightly attached to the surface of the metal product. According to the different extension and retraction lengths of the slide rod 207 in the long strip plate 206, the irregular metal product is clamped and fixed by the clamping plates 209. The operation of the multi-axis adjustment component is controlled, and then the operation of the second motor 301 is controlled, through the thread opening head. Rotating 305 allows for thread milling of metal products. When milling threads of different diameters, the thread cutter 305 needs to be replaced. To do this, manually press down the pressure rod 306. The pressure rod 306 moves the two L-shaped clamping plates 307, removing them from the outside of the corresponding limiting rod 308. Manually flip the second locking plate 303 outwards around the hinge, removing the thread cutter 305 from the opposite side of the second locking plate 303 and the first locking plate 302. Replace with a different model of thread cutter 305. Different types of thread cutters 305 are placed on the opposite side of the first locking plate 302 and the second locking plate 303. The second locking plate 303 is attached to the first locking plate 302 around the hinge, so that several pointed cones 304 are attached to the outer surface of the thread cutter 305. The thrust applied to the pressure rod 306 is removed. Under the action of the second spring 309, an upward thrust is applied to the pressure rod 306, so that the two L-shaped clamping plates 307 are clamped on the corresponding limiting rods 308, thus completing the replacement of the thread cutter 305. The principle is the same as above, and thread milling can be performed on metal products.
