Description

Technical Field

[0001] This utility model relates to the field of tap preparation, and in particular to an automatic wire drawing machine for tap preparation. Background Technology

[0002] A tap is a commonly used threading tool in the machining of parts on a lathe. A typical tap consists of a tool body and a tool holder. The tool body is composed of cutting teeth, chip grooves, and a core. In the process of machining taps, an automatic wire drawing machine is usually used to turn the tap material into threads. During machining, the tool holder is usually clamped, and then the tool body is machined.

[0003] In existing automatic wire drawing machines, the tool holder is usually fixed using a chuck. After processing one tap, it is manually removed from the chuck, and then the raw material to be processed is fixed in the chuck for processing. Although this method is simple, the production efficiency is low. Moreover, due to the friction between the tool and the tool body during wire drawing, the tool body gets very hot and needs to be cooled before it can be removed from the chuck, otherwise it is easy to burn. Therefore, a certain amount of time is required for the tap to cool down. To address this, this solution proposes an automatic wire drawing machine for tap preparation. Utility Model Content

[0004] The automatic wire drawing machine for tap preparation proposed in this utility model solves the problems of low production efficiency and the need for additional time to cool down the taps in the existing automatic wire drawing machines for tap preparation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic wire drawing machine for tap preparation includes a processing table, characterized in that the top surface of the processing table is provided with a fixed platform and a mounting base, a chuck is mounted on the mounting base, a plug rod is fixed on the front of the chuck, and a telescopic component for driving the mounting base to move is mounted on the top surface of the processing table.

[0007] The fixed platform is fixedly connected to the top surface of the processing table, and a mounting plate is rotatably connected to one side of the fixed platform. Multiple fixing mechanisms that cooperate with the chuck are installed on the mounting plate. The fixing mechanism includes a fixing ring rotatably connected to the mounting plate, multiple pressure rods installed in the inner ring of the fixing ring by elastic elements, and an adjusting ring rotatably sleeved on the outer ring of the fixing ring for adjusting the opening and closing of the multiple pressure rods. The side of the fixing ring near the chuck has an insertion hole that matches the insertion rod.

[0008] The top surface of the machining table is equipped with a cutting assembly that cooperates with the chuck.

[0009] The above technical solutions can not only effectively improve the efficiency of tapping, but also save the time of cooling the tap, reducing the difficulty and risk of processing.

[0010] As a further improvement to the above solution, the fixing platform has a hollow structure, and a drive motor for driving the installation plate to rotate is installed inside the fixing platform.

[0011] As a further improvement to the above solution, the outer periphery of the fixed ring is provided with a plurality of mounting holes for mounting elastic elements. The other end of the pressure rod passes through the mounting holes and extends to the outside of the fixed ring. The elastic element includes a spring movably sleeved on the outer periphery of the pressure rod and a fixing block fixed on the other end of the pressure rod. One end of the spring is fixedly connected to the fixing block, and the other end of the spring is fixedly connected to the inner wall of the bottom of the mounting hole.

[0012] The above technical solution utilizes the spring force to clamp the tap with the pressure rod, preventing it from falling off during the rotation of the mounting plate.

[0013] As a further improvement to the above solution, the end of the pressure rod located inside the fixing ring is a right-angled trapezoidal structure, and the inclined surface of the trapezoidal structure faces the side away from the chuck.

[0014] The above technical solution facilitates the insertion of tap material between multiple pressure bars.

[0015] As a further improvement to the above solution, the adjusting ring has multiple sliding grooves on the side near the fixed block. The sliding grooves are inclined, and a fixing post is fixed on the outer periphery of the fixed block. One end of the fixing post extends into the sliding groove and slides with it.

[0016] The above technical solution utilizes an inclined slide groove to move the fixed column outward from the fixed ring as the adjusting ring rotates.

[0017] As a further improvement to the above solution, the number of the insertion rods is set to multiple, and the number of insertion holes is the same as the number of insertion rods.

[0018] As a further improvement to the above solution, the cutting assembly includes a longitudinal moving stage disposed on the top surface of the machining table, a transverse moving stage disposed on the top surface of the longitudinal moving stage, and a tool holder mounted on the top surface of the transverse moving stage. A telescopic member one for driving the longitudinal moving stage to move is mounted on the top surface of the machining table, a telescopic member three for driving the transverse moving stage to move is mounted on the top surface of the longitudinal moving stage, and a tool is mounted on the tool holder.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. By coordinating the mounting plate, fixing mechanism, and chuck, multiple raw materials to be processed can be clamped in advance using the fixing mechanism. Then, when the raw material rotates to face the chuck, the chuck is driven forward. After one end of the raw material enters the chuck, the chuck is activated to clamp the raw material. The insert rod on the chuck, after being inserted into the clasp hole on the fixing ring, can drive the fixing ring to rotate synchronously while the chuck rotates. After the previous raw material is processed, the mounting plate is rotated to rotate the next raw material to be processed to the position facing the chuck, and then it is clamped and fixed, thereby improving production efficiency.

[0021] 2. The clamping mechanism allows both finished and unfinished taps to be fixed on the mounting plate and rotate with it. The multiple clamping mechanisms allow the finished taps to dissipate heat during the rotation of the mounting plate, preventing burns to workers when the taps are removed from the clamping mechanism.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1:

[0031] Please combine Figure 1 - Figure 5 The automatic wire drawing machine for tap preparation in this embodiment includes a processing table 1. The top surface of the processing table 1 is provided with a fixed platform 2 and a mounting base 9. A chuck 11 is installed on the mounting base 9. A plug rod 20 is fixed on the front of the chuck 11. A telescopic component 2 10 for driving the mounting base 9 to move is installed on the top surface of the processing table 1. The chuck 11 is an electric chuck. A transmission motor for driving the chuck 11 to rotate is installed inside the mounting base 9. The chuck clamps the shank of the tap to be processed and then drives the tap to rotate, so that the tool performs turning on the surface of the tap.

[0032] The fixed platform 2 is fixedly connected to the top surface of the processing table 1, and a mounting plate 3 is rotatably connected to one side of the fixed platform 2. The fixed platform 2 has a hollow structure, and a drive motor for driving the mounting plate 3 to rotate is installed inside the fixed platform 2. Multiple fixing mechanisms that cooperate with the chuck 11 are installed on the mounting plate 3. The fixing mechanism includes a fixing ring 4 rotatably connected to the mounting plate 3, multiple pressure rods 15 installed on the inner ring of the fixing ring 4 through elastic elements, and an adjusting ring 14 rotatably sleeved on the outer ring of the fixing ring 4 for adjusting the opening and closing of the multiple pressure rods 15. When drawing wire, the tap material to be processed is first placed inside the fixing ring 4 and clamped with the pressure rods 15. At the same time, the shank of the tap extends to the outside of the fixed ring 4 near the chuck 11. When a certain tap material needs to be processed, the mounting plate 3 is driven to rotate, thereby rotating the tap material to be processed to the position directly opposite the chuck 11. Then, extend the telescopic component 10 to bring the chuck 11 closer to the mounting plate 3. After the shank of the tap material enters the inside of the chuck 11, the chuck 11 clamps the tap material. Then, the tool can be used to turn the tap material. After processing, the tap is released and the telescopic component 10 retracts, and the processed tap is withdrawn outside the chuck. Then, the drive motor is started to drive the mounting plate 3 to rotate, thereby rotating the tap material clamped in the next fixing mechanism to the position directly opposite the chuck 11. Then, the telescopic component 10 is extended again, and the tap material is clamped again. Finally, it is cut. This operation is repeated to achieve efficient processing. Moreover, the processed tap can also dissipate heat and cool down during the rotation and rest of the mounting plate 3, so that it will not burn the workers when it is removed from the fixing mechanism.

[0033] The fixed ring 4 has a socket 13 on the side near the chuck 11 that matches the insertion rod 20. There are multiple insertion rods 20, and the number of sockets 13 is the same as the number of insertion rods 20. As the chuck 11 moves closer to the mounting plate 3, the insertion rods 20 are aligned with the sockets 13 until the insertion rods 20 are inserted into the sockets 13. This allows the fixed ring 4 to rotate synchronously during the rotation of the chuck 11, thus preventing friction between the tap material and the pressure plate.

[0034] The end of the pressure bar 15 located inside the fixed ring 4 is a right-angled trapezoidal structure, and the inclined surface of the trapezoidal structure faces away from the chuck 11. The trapezoidal structure allows the tap material to enter more smoothly between the multiple pressure bars 15 and be clamped by them during the process of inserting into the inner side of the fixed ring 4.

[0035] The top surface of the machining table 1 is equipped with a cutting assembly that cooperates with the chuck 11. The cutting assembly includes a longitudinal moving table 7 on the top surface of the machining table 1, a transverse moving table 6 on the top surface of the longitudinal moving table 7, and a tool holder 5 on the top surface of the transverse moving table 6. The top surface of the machining table 1 is equipped with a telescopic member 1 8 for driving the longitudinal moving table 7 to move, and the top surface of the longitudinal moving table 7 is equipped with a telescopic member 3 12 for driving the transverse moving table 6 to move. A tool is mounted on the tool holder 5. After the tool contacts the surface of the tap material, it can cut it. The extension and retraction of the telescopic member 1 8 can drive the tool to move longitudinally, and the extension and retraction of the telescopic member 3 12 can drive the tool to move laterally, thereby facilitating the adjustment of the tool's position.

[0036] In this embodiment, telescopic component 1 (8), telescopic component 2 (10), and telescopic component 3 (12) are all electric telescopic rods.

[0037] Example 2:

[0038] Combination Figure 3 and Figure 4 Based on Embodiment 1, this embodiment further improves upon the following: the outer periphery of the fixing ring 4 is provided with multiple mounting holes 18 for mounting elastic elements. The other end of the pressure rod 15 passes through the mounting holes 18 and extends to the outside of the fixing ring 4. The elastic element includes a spring movably sleeved on the outer periphery of the pressure rod 15 and a fixing block 16 fixed on the other end of the pressure rod 15. One end of the spring is fixedly connected to the fixing block 16, and the other end of the spring is fixedly connected to the bottom inner wall of the mounting hole 18. The spring arrangement causes the pressure rod 15 to have an automatic tendency to move towards the inside of the fixing ring 4 after being squeezed to the outside of the fixing ring 4. Thus, the tap material can be inserted between the multiple pressure rods 15 and clamped by the multiple pressure rods 15.

[0039] Multiple sliding grooves 19 are provided on the side of the adjusting ring 14 near the fixed block 16. The sliding grooves 19 are inclined. A fixed post 17 is fixed on the outer periphery of the fixed block 16. One end of the fixed post 17 extends into the sliding groove 19 and slides with it. When it is necessary to loosen the tap clamped by the pressure rod 15, the adjusting ring 14 can be rotated clockwise. The sliding groove 19 rotates synchronously with the adjusting ring 14. At this time, the fixed post 17 will move along the sliding groove 19 to the outside of the adjusting ring 14 under the rotation of the sliding groove 19, thereby driving the pressure rod 15 to move to the outside of the fixed ring 4. The spring is stretched, which can loosen the clamped tap, thereby achieving the purpose of conveniently driving multiple pressure rods 15 to move to the outside of the fixed ring 4. Conversely, after the adjusting ring 14 is loosened, the spring returns to its deformation, which can drive the pressure rod 15 to return to its original position.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
