Description

Technical Field

[0001] This utility model relates to the field of shaft workpiece processing technology, and in particular to a shaft workpiece loading and unloading device and lathe. Background Technology

[0002] In the production process of shaft-type workpieces, a lathe is required to machine the outer wall of the shaft-type workpiece. Existing shaft-type workpieces, such as... Figure 1 As shown, a small hole 110 is provided on both end faces of the shaft workpiece 100. When machining shaft workpieces using existing lathes (such as the long shaft workpiece machining lathe disclosed in application number 202022480388.3), the shaft workpiece must first be clamped. During clamping, manual loading is required, and after machining, the shaft workpiece still needs to be manually removed. This makes continuous machining of shaft workpieces impossible, easily consuming a long time in loading and unloading, resulting in low machining efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a shaft workpiece loading and unloading device and lathe to solve the technical problem that manual loading and unloading in the prior art cannot achieve continuous cutting of shaft workpieces, and easily takes a long time for loading and unloading, resulting in low cutting efficiency of shaft workpieces.

[0004] To achieve the above-mentioned technical objectives, the present invention provides a shaft-type workpiece loading and unloading device, which is disposed on one side of the clamping mechanism of a lathe, comprising:

[0005] A hopper, which is used to stack multiple shaft-type workpieces;

[0006] The feeding mechanism includes a feeding seat, a first driving component and a second driving component. The first driving component is connected to the feeding seat and is used to drive the feeding seat to alternately reach the hopper or the clamping mechanism. The second driving component is used to push a single shaft-type workpiece in the hopper onto the feeding seat.

[0007] The unloading mechanism includes a receiving seat and a third drive assembly. The third drive assembly is connected to the receiving seat and is used to drive the receiving seat to alternately move to the underside or side of the clamping mechanism.

[0008] Furthermore, the hopper has a top-opening material cavity, in which multiple shaft-type workpieces are horizontally stacked from bottom to top. The shaft-type workpieces in the material cavity are horizontal to the shaft-type workpieces clamped by the clamping mechanism. A discharge port communicating with the material cavity is opened on one side wall of the hopper, and a slot communicating with the material cavity is opened on the other side wall of the hopper. The slot corresponds to the discharge port and is used for the output end of the second drive component to slide through.

[0009] Furthermore, the feeding seat includes a first seat body, a baffle, and an elastic element. The first seat body has a receiving channel that extends horizontally and is parallel to the shaft-like workpiece. Both ends of the receiving channel and one side wall near the clamping mechanism are open. The receiving channel is used to receive a single shaft-like workpiece. The baffle is disposed at the opening of the side wall of the receiving channel and is movably connected to the first seat body. The elastic element connects the first seat body and the baffle so that the baffle blocks the opening of the side wall of the receiving channel.

[0010] Furthermore, the bottom of the baffle is rotatably connected to the first seat via a pin, the elastic element is a torsion spring, the torsion spring is sleeved on the pin, and the two ends of the torsion spring are respectively fixedly connected to the first seat and the baffle.

[0012] Furthermore, the second driving component includes a push block and a second telescopic driving member. The push block is disposed at the slot, and the output end of the second telescopic driving member is fixedly connected to the push block. It is used to drive the push block to move horizontally and reciprocally along the length direction of the shaft workpiece so that the push block abuts against the bottommost shaft workpiece in the material cavity and pushes the bottommost shaft workpiece into the receiving channel.

[0013] Furthermore, the receiving seat includes a base plate and a second seat body. The base plate is horizontally arranged, and the second seat body is disposed on the base plate. One end of the second seat body is rotatably connected to the base plate via a pin, and the other end of the second seat body is suspended. A receiving channel is provided on the second seat body. The receiving channel extends horizontally and is parallel to the shaft workpiece. Both ends and the top of the receiving channel are open. The receiving channel is used to receive the processed shaft workpiece.

[0014] Furthermore, the third driving assembly includes a third telescopic driving member and a guide plate. The output end of the third telescopic driving member is fixedly connected to the base plate and is used to drive the base plate to move horizontally reciprocally along a length perpendicular to the shaft-like workpiece. The guide plate is vertically disposed at the other end of the second seat and is perpendicular to the shaft-like workpiece. The top of the guide plate has a plane and an inclined surface connected in sequence. The plane is close to the clamping mechanism, and the inclined surface is away from the clamping mechanism. The top of the guide plate slides against the other end of the second seat. During the horizontal reciprocating movement of the base plate along a length perpendicular to the shaft-like workpiece, the plane and the inclined surface alternately slide against the other end of the second seat. When the plane slides against the other end of the second seat, the receiving channel is in a horizontal state. When the inclined surface slides against the other end of the second seat, the receiving channel is in an inclined state.

One end of each guide rod is fixedly connected to the first seat body, and the other end of each guide rod is slidably connected to the bracket.

[0016] On the other hand, this utility model also provides a lathe, including a clamping mechanism, the aforementioned shaft workpiece loading and unloading device, and a cutting mechanism. The clamping mechanism includes a first chuck, a second chuck, a rotating assembly, and a moving assembly. Both the first chuck and the second chuck are columnar structures, horizontally arranged and opposite to each other. The adjacent ends of the first chuck and the second chuck are pointed structures. The rotating assembly is connected to the other end of the first chuck and is used to drive the first chuck to rotate around its central axis. The moving assembly is connected to the other end of the second chuck and is used to drive the second chuck to move horizontally and reciprocally along its axial direction, so that the adjacent ends of the first chuck and the second chuck are respectively inserted into two small holes of the shaft workpiece, or so that the adjacent ends of the first chuck and the second chuck are respectively removed from the two small holes of the shaft workpiece. The cutting mechanism is arranged on the other side of the clamping mechanism and is used to cut the shaft workpiece clamped by the clamping mechanism.

[0023] This utility model provides a device for loading and unloading shaft-type workpieces, which is disposed on one side of the clamping mechanism 200 of a lathe, and its structure is as follows. Figure 2 - Figure 3 As shown, the device includes a hopper 300, a feeding mechanism 400, and a discharging mechanism 500. The hopper 300 is used to stack multiple shaft-type workpieces 100. The feeding mechanism 400 includes a feeding seat 410, a first driving component 420, and a second driving component 430. The first driving component 420 is connected to the feeding seat 410 and is used to drive the feeding seat 410 to alternately reach the hopper 300 or the clamping mechanism 200.

The discharging mechanism 500 includes a receiving seat 510 and a third driving component 520. The third driving component 520 is connected to the receiving seat 510 and is used to drive the receiving seat 510 to alternately reach directly below or to the side of the clamping mechanism 200.

[0024] In use, all shaft-type workpieces 100 to be processed are stacked in the hopper 300. By operating the first drive component 420, the first drive component 420 can drive the feed seat 410 to the hopper 300. When the feed seat 410 reaches the hopper 300, by operating the second drive component 430, the second drive component 430 can push a single shaft-type workpiece 100 in the hopper 300 onto the feed seat 410. Then, by operating the first drive component 420, the first drive component 420 can drive the feed seat 410 to the clamping mechanism 200. When the feed seat 410 reaches the clamping mechanism 200, by operating the clamping mechanism 200, the clamping mechanism 200 can clamp and fix the shaft-type workpiece 100. The loading mechanism 400 can realize the self-loading process of the shaft-type workpiece 100. Then, by operating the... The first drive component 420 can drive the feed seat 410 to the hopper 300 again. After the shaft workpiece 100 is processed, by operating the third drive component 520, the third drive component 520 can drive the receiving seat 510 to the bottom of the clamping mechanism 200. At this time, the clamping mechanism 200 releases the shaft workpiece 100, and the shaft workpiece 100 falls on the receiving seat 510. Then, by operating the third drive component 520, the third drive component 520 can drive the receiving seat 510 to the side of the clamping mechanism 200. The unloading mechanism 500 can realize the self-unloading process of the shaft workpiece 100. This shaft workpiece loading and unloading device can perform self-loading and self-unloading of the shaft workpiece 100, realize continuous cutting of the shaft workpiece 100, reduce the time occupied in loading and unloading, and improve the cutting efficiency of the shaft workpiece 100.

[0025] As a preferred embodiment, please refer to Figure 2 and Figure 3The hopper 300 has a top-opening material cavity 310, in which multiple shaft-type workpieces 100 are horizontally stacked from bottom to top. The shaft-type workpieces 100 in the material cavity 310 are horizontally aligned with the shaft-type workpieces 100 clamped by the clamping mechanism 200. A discharge port 320 communicating with the material cavity 310 is provided on one side wall of the hopper 300. The diameter of the discharge port 320 is equal to the diameter of the shaft-type workpieces 100. A single shaft-type workpiece 100 in the material cavity 310... The material can be discharged through the discharge port 320. A slot 330 communicating with the material cavity 310 is provided on the other side wall of the hopper 300. The slot 330 corresponds to the discharge port 320. The slot 330 is used for the output end of the second drive component 430 to slide through, so that the output end of the second drive component 430 can pass through the slot 330 and extend into the material cavity 310, pushing out the bottommost single shaft workpiece 100 in the material cavity 310.

[0026] As a preferred embodiment, please refer to Figure 2 and Figure 3The feeding seat 410 includes a first seat body 411, a baffle 412, and an elastic element 413. The first seat body 411 has a receiving channel 4111 extending horizontally and parallel to the shaft-type workpiece 100. Both ends of the receiving channel 4111 and one side wall near the clamping mechanism 200 are open. The receiving channel 4111 is used to receive a single shaft-type workpiece 100. The baffle 412 is disposed at the opening of the side wall of the receiving channel 4111 and is movably connected to the first seat body 411. The elastic element 413 connects to... The first seat 411 and the baffle 412 are configured such that the baffle 412 blocks the opening on the side wall of the receiving channel 4111. When the first seat 411 reaches the hopper 300, the receiving channel 4111 communicates with the discharge port 320. By operating the second drive assembly 430, the second drive assembly 430 can push a single shaft-like workpiece 100 in the hopper 300 into the receiving channel 4111. Then, by operating the first drive assembly 420, the first drive assembly 420 can drive the first seat 411 to the clamping mechanism 20. At position 0, when the first seat 411 reaches the clamping mechanism 200, the receiving channel 4111 corresponds to the clamping mechanism 200. By operating the clamping mechanism 200, the clamping mechanism 200 can clamp and fix the shaft workpiece 100. Then, by operating the first drive component 420, the first drive component 420 can drive the first seat 411 to reach the hopper 300 again. When the first drive component 420 drives the first seat 411 back, the shaft workpiece 100 in the receiving channel 4111 is clamped by the clamping mechanism. The clamping and fixing at 200 causes the shaft workpiece 100 to be unable to return with the first seat 411. The first seat 411 and the shaft workpiece 100 generate relative movement. The shaft workpiece 100 will push the baffle 412 away from the opening of the side wall of the receiving channel 4111 until the shaft workpiece 100 passes the baffle 412. During this process, the elastic element 413 generates elastic deformation and accumulates elastic potential energy. When the shaft workpiece 100 passes the baffle 412, the elastic element 413 releases the elastic potential energy, causing the baffle 412 to block the opening of the side wall of the receiving channel 4111 again.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3The bottom of the baffle 412 is rotatably connected to the first seat 411 via a pin. The elastic element 413 is a torsion spring, which is sleeved on the pin, and both ends of the torsion spring are fixedly connected to the first seat 411 and the baffle 412, respectively. When the first drive assembly 420 drives the first seat 411 to return, the shaft workpiece 100 in the receiving channel 4111 is clamped and fixed by the clamping mechanism 200, causing the shaft workpiece 100 to not return with the first seat 411. 1. When relative motion occurs between the shaft workpiece 100 and the baffle 412, the shaft workpiece 100 will push the baffle 412 to rotate in the forward direction around its pin, moving away from the opening of the side wall of the receiving channel 4111 until the shaft workpiece 100 passes the baffle 412. During this process, the torsion spring will generate tensile elastic deformation and accumulate tensile elastic potential energy. When the shaft workpiece 100 passes the baffle 412, the torsion spring will release the tensile elastic potential energy, causing the baffle 412 to rotate in the reverse direction around its pin, and blocking the opening of the side wall of the receiving channel 4111 again.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3 The first drive assembly 420 includes a first telescopic drive member 421. The output end of the first telescopic drive member 421 is fixedly connected to the first seat body 411 and is used to drive the first seat body 411 to move horizontally reciprocally along the length perpendicular to the shaft workpiece 100. By operating the first telescopic drive member 421, the first telescopic drive member 421 can drive the first seat body 411 to move horizontally reciprocally along the length perpendicular to the shaft workpiece 100, so that the first seat body 411 alternately reaches the hopper 300 or the clamping mechanism 200.

The push block 431 is disposed at the slot 330. The output end of the second telescopic driving member 432 is fixedly connected to the push block 431 and is used to drive the push block 431 to move horizontally reciprocally along the length direction of the shaft workpiece 100, so that the push block 431 abuts against the bottommost shaft workpiece 100 in the material cavity 310 and pushes the bottommost shaft workpiece 100 into the receiving channel 4111. By operating the second telescopic driving member 432, the second telescopic driving member 432 can drive the push block 431 to move horizontally reciprocally along the length direction of the shaft workpiece 100, so that the push block 431 abuts against the bottommost shaft workpiece 100 in the material cavity 310 and pushes the bottommost shaft workpiece 100 into the receiving channel 4111.

[0031] In a preferred embodiment, the second telescopic drive member 432 can be directly connected to the push block 431 using a suitable type of second cylinder, or it can be indirectly connected to the push block 431 using a gear set or a sliding set.

A receiving channel 5121 is formed on the second seat body 512. The receiving channel 5121 extends horizontally and is parallel to the shaft workpiece 100. Both ends and the top of the receiving channel 5121 are open. The receiving channel 5121 is used to receive the processed shaft workpiece 100. After the shaft workpiece 100 is processed, by operating the third drive component 520, the third drive component 520 can drive the base plate 511 to the bottom of the clamping mechanism 200. At this time, the clamping mechanism 200 releases the shaft workpiece 100, and the shaft workpiece 100 falls into the receiving channel 5121. Then, by operating the third drive component 520, the third drive component 520 can drive the base plate 511 to the side of the clamping mechanism 200.

During the horizontal reciprocating movement of the base plate 511 along a length perpendicular to the shaft workpiece 100, the plane 5221 and the inclined surface 5222 alternately slide against the other end of the second base 512. When the plane 5221 slides against the other end of the second base 512, the receiving channel 5121 is in a horizontal state. When the inclined surface 5222 slides against the other end of the second base 512, the receiving channel 5121 is in a horizontal state. When the end slides and abuts, the receiving channel 5121 is in an inclined state. After the shaft workpiece 100 is processed, by operating the third telescopic drive member 521, the third telescopic drive member 521 can drive the base plate 511 to directly below the clamping mechanism 200. At this time, the clamping mechanism 200 releases the shaft workpiece 100, and the shaft workpiece 100 falls into the receiving channel 5121. Then, by operating the third telescopic drive member 521, the third telescopic drive member 521 can drive the base plate 511 to the clamping mechanism. On the side of 200, when the third telescopic drive member 521 drives the base plate 511 to return, the plane 5221 and the inclined surface 5222 will slide and abut against the other end of the second seat body 512 in sequence. When the inclined surface 5222 slides and abuts against the other end of the second seat body 512, the receiving channel 5121 is in an inclined state. At this time, the other end of the second seat body 512 is higher than one end of the second seat body 512, and the shaft workpiece 100 in the receiving channel 5121 slides down along the receiving channel 5121 to realize the unloading.

The cutting mechanism is disposed on the clamping mechanism. On the other side of the clamping mechanism 200, the first seat 411 is used to cut the shaft workpiece 100 clamped by the clamping mechanism 200.

Then, by manipulating the first telescopic drive 421, the first seat 411 can be driven to the clamping mechanism 200. When the first seat 411 reaches the clamping mechanism 200, it is positioned between the first chuck 210 and the second chuck 220, and the shaft workpiece 100 in the receiving channel 4111 is coaxial with the first chuck 210 and the second chuck 220. By manipulating the moving component 240, the moving component 240 can drive the second chuck 220 horizontally along its axial direction. The movement allows the adjacent ends of the first chuck 210 and the second chuck 220 to be inserted into the two small holes 110 of the shaft workpiece 100, thereby clamping and fixing the shaft workpiece 100. The feeding mechanism 400 enables the self-feeding process of the shaft workpiece 100. Then, by manipulating the first telescopic drive 421, the first seat 411 can be driven back to the hopper 300. When the first drive assembly 420 drives the first seat 411 back, the shaft workpiece 100 in the receiving channel 4111, being clamped and fixed by the clamping mechanism 200, cannot return with the first seat 411. The shaft 411 moves relative to the shaft workpiece 100, causing the shaft workpiece 100 to push the baffle 412 away from the opening in the side wall of the receiving channel 4111 until the shaft workpiece 100 passes the baffle 412. During this process, the elastic element 413 undergoes elastic deformation and accumulates elastic potential energy. After the shaft workpiece 100 passes the baffle 412, the elastic element 413 releases the elastic potential energy, causing the baffle 412 to block the opening in the side wall of the receiving channel 4111 again. By manipulating the rotating assembly 230, the rotating assembly 230 can drive the first chuck 210 to rotate around its central axis. During this process, the cutting mechanism performs cutting processing on the shaft workpiece 100. After the shaft workpiece 100 is processed...By manipulating the third telescopic drive member 521, the base plate 511 can be driven to directly below the clamping mechanism 200. At this time, the clamping mechanism 200 releases the shaft workpiece 100, and the shaft workpiece 100 falls into the receiving channel 5121. Then, by manipulating the third telescopic drive member 521, the base plate 511 can be driven to the side of the clamping mechanism 200. When the third telescopic drive member 521 drives the base plate 511 back, the plane 5221 and the inclined surface 5222 will sequentially slide and abut against the other end of the second seat 512. When the inclined surface 5222 slides against the other end of the second seat 512, the receiving channel 5121 is in an inclined state. At this time, the other end of the second seat 512 is higher than one end of the second seat 512. The shaft workpiece 100 in the receiving channel 5121 slides down along the receiving channel 5121, realizing the unloading. The unloading mechanism 500 can realize the self-unloading process of the shaft workpiece 100. This shaft workpiece loading and unloading device can perform self-loading and self-unloading of the shaft workpiece 100, realize continuous cutting of the shaft workpiece 100, reduce the time occupied in loading and unloading, and improve the cutting efficiency of the shaft workpiece 100.

[0042] The present invention provides a shaft-type workpiece loading and unloading device and a lathe, which have the following beneficial effects:

[0043] (1) When the first drive assembly 420 drives the first seat 411 to return, the shaft workpiece 100 in the accommodating channel 4111 is clamped and fixed by the clamping mechanism 200, causing the shaft workpiece 100 to not return with the first seat 411. The first seat 411 and the shaft workpiece 100 generate relative movement. The shaft workpiece 100 will push the baffle 412 to rotate in the forward direction around its pin and move away from the opening of the side wall of the accommodating channel 4111 until the shaft workpiece 100 passes the baffle 412. During this process, the torsion spring generates tensile elastic deformation and accumulates tensile elastic potential energy. When the shaft workpiece 100 passes the baffle 412, the torsion spring releases the tensile elastic potential energy, causing the baffle 412 to rotate in the reverse direction around its pin and block the opening of the side wall of the accommodating channel 4111 again.

[0044] (2) After the shaft workpiece 100 is processed, by operating the third telescopic drive member 521, the third telescopic drive member 521 can drive the base plate 511 to the side of the clamping mechanism 200. At this time, the clamping mechanism 200 releases the shaft workpiece 100, and the shaft workpiece 100 falls into the receiving channel 5121. Then, by operating the third telescopic drive member 521, the third telescopic drive member 521 can drive the base plate 511 to the side of the clamping mechanism 200. When the three telescopic drive members 521 drive the base plate 511 to return, the plane 5221 and the inclined surface 5222 will slide and abut against the other end of the second seat 512 in sequence. When the inclined surface 5222 slides and abuts against the other end of the second seat 512, the receiving channel 5121 is in an inclined state. At this time, the other end of the second seat 512 is higher than one end of the second seat 512, and the shaft workpiece 100 in the receiving channel 5121 slides down along the receiving channel 5121 to realize the unloading.

[0045] (3) This shaft workpiece loading and unloading device can load and unload shaft workpiece 100 by itself, realize continuous cutting of shaft workpiece 100, reduce the time occupied in loading and unloading, and improve the cutting efficiency of shaft workpiece 100.
