Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically a tapping machine for machining shaft workpieces. Background Technology

[0002] In the field of mechanical manufacturing, shafts are indispensable key components in various mechanical equipment, and their machining accuracy and quality directly affect the performance, reliability, and service life of the entire equipment. Tapping, as one of the important processes in shaft machining, aims to produce internal threaded holes that meet the requirements for connection and assembly with other components.

[0003] Currently, most tapping machines on the market use a fixture to fix the shaft to the worktable when machining shaft workpieces. This traditional fixing method has revealed many limitations in practical applications, the most prominent of which is the limited range of machined end faces. Specifically, when using existing tapping machines to tap shaft workpieces, due to the limitations of the fixture's fixing position and method, the tapping tool can usually only machine one end face of the shaft. When tapping the other end face of the shaft is required, the operator has to remove the shaft from the fixture, readjust the shaft's clamping position, and then fix it again before machining the other end face. This repetitive clamping process is not only tedious and complex but also greatly increases processing time and labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a tapping machine for machining shaft workpieces. It uses a clamping block to fix the shaft to be machined, and rotates the rotating plate to flip the shaft to be machined so that the other end face of the shaft can be machined.

[0005] To address the problems of existing technologies, this utility model provides a tapping machine for machining shaft workpieces, characterized by comprising: a main body; a tapping assembly disposed on the back of the top of the main body for tapping the end face of the shaft to be machined; a support assembly disposed on the front of the top of the main body for supporting the shaft to be machined; and a clamping assembly disposed on the top of the main body and directly in front of the support assembly for fixing the shaft to be machined and for flipping the shaft to be machined; the clamping assembly includes a support plate fixed to the top of the main body, a rotatable rotating plate rotatably disposed on the support plate near the front of the shaft to be machined, and two synchronously movable clamping blocks disposed on the rotating plate for contacting the surface of the shaft to be machined and fixing the shaft; the clamping assembly further includes a drive mechanism disposed on the side of the support plate away from the rotating plate for driving the rotating plate to rotate.

[0006] Preferably, the front of the rotating plate is further provided with a slide rail, and the back of the clamping block is further provided with a slider that can slide and cooperate with the slide rail.

[0007] Preferably, the clamping assembly further includes a second telescopic drive member vertically fixed on the rotating plate for driving the clamping block closer to or away from the axis to be processed. The output end of the second telescopic drive member is hinged to a connecting rod via a shaft. The other end of the connecting rod is movably connected to the slider. The cross-section of the connecting rod is "L" shaped. The connecting rod is also movably connected to the rotating plate via a shaft. Furthermore, the back of the rotating plate is provided with a rotating shaft that rotatably cooperates with the support plate.

[0008] Preferably, the driving mechanism includes a worm gear sleeved on a rotating shaft on a rotating plate, and the driving mechanism also includes a worm meshing with the worm gear. The rotating plate also includes a third rotary driving member disposed on the back of the support plate and used to drive the worm to rotate, and the output end of the third rotary driving member is connected to the worm.

[0009] Preferably, the clamping part of the clamping block is "V" shaped.

[0010] Preferably, the support assembly includes a sleeve disposed on the top of the main body, and a lifting platform capable of moving up and down is disposed in the sleeve. The support assembly also includes a first telescopic drive component fixed to the bottom of the main body and used to drive the lifting platform to move up and down.

[0011] Preferably, the tapping assembly includes a vertical plate vertically arranged on the top of the main body, and a guide rod is vertically arranged at the front of the vertical plate. A lifting plate that can move up and down is slidably arranged on the guide rod. A first rotary drive is fixed at the top of the lifting plate, and a tool holder is rotatably arranged at the bottom of the lifting plate. A tap is held in the tool holder, and the output end of the first rotary drive is connected to the tool holder.

[0012] Preferably, the tapping assembly further includes a lead screw that is vertically rotatably disposed in the vertical plate, and the lead screw is connected to the lifting plate by a thread. The tapping assembly also includes a second rotary drive component that is fixed to the top of the vertical plate and is used to drive the lead screw to rotate.

[0013] The advantages of this utility model compared to the prior art are:

[0014] This application uses two sliders that move synchronously to fix the shaft to be processed. Specifically, the second telescopic drive activates, converting its telescopic motion at the output end into the rotation of a connecting rod. Under the transmission action of the connecting rod, the two sliders move closer together until they are in close contact with the shaft to be processed, thus reliably fixing the shaft and ensuring its positional stability during subsequent tapping. After the tapping machine completes the tapping operation on one end face of the shaft to be processed, the third rotary drive is activated. The third rotary drive outputs rotational power, driving the worm gear to rotate. Due to the meshing relationship between the worm gear and the worm wheel, the rotation of the worm gear drives the rotation of the worm wheel. The worm wheel is fixedly connected to the rotating plate, thereby driving the rotating plate to rotate. As the rotating plate rotates, the tapping machine can process the other end face of the shaft to be processed. This process eliminates the need to reclamp the shaft to be processed, effectively improving processing efficiency. Attached Figure Description

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6 As shown, this utility model provides a tapping machine for machining shaft workpieces, including: a main body 1; a tapping assembly 2, which is disposed on the back of the top of the main body 1 for tapping the end face of the shaft to be machined; a support assembly 3, which is disposed on the front of the top of the main body 1 for supporting the shaft to be machined; and a clamping assembly 4, which is disposed on the top of the main body 1 and located directly in front of the support assembly 3 to fix the shaft to be machined and to flip the shaft to be machined. The clamping assembly 4 includes a support plate 41 fixed to the top of the main body 1, and a rotatable rotating plate 47 is rotatably disposed on the support plate 41 near the front of the shaft to be machined. The rotating plate 47 is provided with two synchronously movable clamping blocks 43 that contact the surface of the shaft to be machined to fix the shaft. The clamping part of the clamping block 43 is "V" shaped. The clamping assembly 4 also includes a drive mechanism 46 disposed on the side of the support plate 41 away from the rotating plate 47 for driving the rotating plate 47 to rotate.

[0024] When the tapping machine for machining shaft workpieces is in operation, the shaft to be machined is first placed on the support assembly 3 and fixed by the clamping block 43 in the clamping assembly 4. The clamping block 43 can move synchronously, and its "V"-shaped clamping part can adapt to shafts of different diameters, ensuring that the shaft is stably clamped and preventing the shaft from moving during the tapping process. When it is necessary to tap one end face of the shaft, the tapping assembly 2 starts working to perform the tapping operation on the end face of the shaft to be machined. After tapping one end face is completed, the drive mechanism 46 starts, driving the rotating plate 47 to rotate. The rotating plate 47 drives the clamping block 43 and the clamped shaft to be machined to rotate together, so that the other end face of the shaft faces the tapping assembly 2. The tapping assembly 2 then works again to perform the tapping operation on the other end face of the shaft. In this way, tapping of different end faces of the shaft to be machined is achieved, improving machining efficiency.

[0025] The front of the rotating plate 47 is also provided with a slide rail 471, and the back of the clamping block 43 is also provided with a slider 42 that can slide and cooperate with the slide rail 471. The clamping assembly 4 also includes a second telescopic drive member 45 that is vertically fixed on the rotating plate 47 for driving the clamping block 43 to move closer to or away from the axis to be processed. The output end of the second telescopic drive member 45 is hinged to a connecting rod 44 through a shaft. The other end of the connecting rod 44 is movably connected to the slider 42. The cross section of the connecting rod 44 is "L" shaped. The connecting rod 44 is also movably connected to the rotating plate 47 through a shaft, and the back of the rotating plate 47 is also provided with a rotating shaft that rotates and cooperates with the support plate 41.

[0026] When the tapping machine for machining shaft workpieces is working, the shaft to be machined is placed near the rotating plate 47. The second telescopic drive 45 starts to work, and its output end telescopic movement drives the slider 42 to slide on the slide rail 471 through the transmission action of the connecting rod 44, thereby bringing the clamping block 43 close to the shaft to be machined, and the shaft is stably clamped by the "V" shaped clamping part.

[0027] The drive mechanism 46 includes a worm gear 461 mounted on a rotating shaft on a rotating plate 47. The drive mechanism 46 also includes a worm 462 meshing with the worm gear 461. The rotating plate 47 also includes a third rotary drive member 463 disposed on the back of the support plate 41 and used to drive the worm 462 to rotate. The output end of the third rotary drive member 463 is connected to the worm 462.

[0028] When tapping is required on one end face of a shaft, the tapping assembly 2 performs the tapping operation on that end face. After tapping one end face, the drive mechanism 46 starts working. The third rotary drive component 463 starts, and its output end drives the worm 462 to rotate. Since the worm 462 meshes with the worm wheel 461, the rotational motion of the worm 462 is transmitted to the worm wheel 461, causing the worm wheel 461 to rotate. The worm wheel 461 is sleeved on the rotating shaft, thereby driving the rotating shaft and the rotating plate 47 to rotate together, realizing the flipping of the shaft to be processed, so that the other end face of the shaft faces the tapping assembly 2. During the flipping process, the self-locking characteristics of the worm 462 and the worm wheel 461 ensure the stability of the rotating plate 47, preventing it from rotating accidentally due to external forces or other factors. After the flipping is completed, the tapping assembly 2 works again to perform the tapping operation on the other end face of the shaft.

[0029] The support assembly 3 includes a sleeve 31 disposed on the top of the main body 1, and a lifting platform 32 capable of moving up and down is disposed in the sleeve 31. The support assembly 3 also includes a first telescopic drive member 33 fixed to the bottom of the main body 1 and used to drive the lifting platform 32 to move up and down.

[0030] The first telescopic drive component 33 starts working, and its output end extends and retracts, pushing the lifting platform 32 to move up and down inside the sleeve 31, so that the lifting platform 32 contacts the bottom end of the shaft to be processed, providing support for the shaft to be processed.

[0031] The tapping assembly 2 includes a vertical plate 21 vertically mounted on the top of the main body 1, and a guide rod 22 vertically mounted on the front of the vertical plate 21. A lifting plate 23, which can move up and down, is slidably mounted on the guide rod 22. A first rotary drive member 24 is fixed to the top of the lifting plate 23, and a tool holder is rotatably mounted on the bottom of the lifting plate 23. A tap 25 is held in the tool holder, and the output end of the first rotary drive member 24 is connected to the tool holder. The tapping assembly 2 also includes a lead screw 27 vertically rotatably mounted in the vertical plate 21, and the lead screw 27 is threadedly connected to the lifting plate 23. The tapping assembly 2 also includes a second rotary drive member 26 fixed to the top of the vertical plate 21 and used to drive the lead screw 27 to rotate.

[0032] When tapping begins, the second rotary drive 26 is activated, driving the leadscrew 27 to rotate. The leadscrew 27, through its threaded engagement with the lifting plate 23, causes the lifting plate 23 to move downwards along the guide rod 22, gradually bringing the tap 25 closer to the end face of the shaft to be tapped. Simultaneously, the first rotary drive 24 is activated, driving the tool holder and tap 25 to rotate. The tap 25 feeds downwards as it rotates, performing the tapping operation on the end face of the shaft to be tapped.

[0033] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
