Description

Technical Field

[0001] This utility model relates to the field of Swiss-type lathe technology, and in particular to an automatic feeding device for Swiss-type lathes. Background Technology

[0002] When using a Swiss-type lathe, the feeding method is mostly manual, that is, the operator manually clamps the bar stock onto the spindle of the Swiss-type lathe. Similarly, the processing of bar stock is also done manually, which makes the processing efficiency of bar stock very low.

[0003] In view of this, Chinese utility model patent CN206123288U discloses an automatic feeding device for a Swiss-type headstock machine. The device includes a frame next to the headstock machine, with a feeding trough extending into the machine. Above the feeding trough, a storage trough for storing bar stock is located on the frame. The bar stock is placed parallel to the feeding trough in the storage trough. A shifting component at the bottom of the storage trough transfers the bar stock from the storage trough to the feeding trough. A drive component on the frame delivers the bar stock, now in the feeding trough, into the headstock machine. During feeding, the bar stock is first stored in the storage trough, parallel to the feeding trough. The shifting component pushes the bar stock from the storage trough into the feeding trough. Once the bar stock is in the feeding trough, the drive component drives it to slide within the trough. Since the feeding trough extends into the headstock machine, when the bar stock moves to the end of the feeding trough under the drive of the drive component, the main shaft clamps the bar stock, completing the feeding process. However, during the process of the bar stock sliding in the feed trough, there is a lot of friction between the bar stock and the feed trough. This friction will cause wear on the bar stock and the feed trough, affecting the surface quality of the bar stock.

[0004] Therefore, it is necessary to improve upon the shortcomings of the existing technologies mentioned above. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic feeding device for Swiss-type lathes, which addresses the shortcomings of the prior art and solves the problem of wear caused by friction between the bar stock and the feeding groove, thus affecting the surface quality of the bar stock.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a Swiss-type lathe, comprising a frame, a feeding trough block and a hopper located above the feeding trough block on the frame, a storage trough extending vertically through the hopper, the storage trough being located to the side of the feeding trough block, a transfer mechanism at the bottom of the storage trough block for transferring bar stock from the storage trough block to the feeding trough block, a discharge trough block on one side of the feeding trough block on the frame, a fixed base plate fixedly connected to the bottom of the feeding trough block, a drive mechanism between the fixed base plate and the frame for driving the fixed base plate to slide horizontally and linearly, the feeding trough block being divided into a first trough block and a second trough block, the first trough block... The device is fixedly installed on a fixed base plate. A fixed baffle is fixedly installed on the side of the fixed base plate near the second slot block. Guide rods are connected to both ends of the fixed baffle and the first slot block. The second slot block has through holes at both ends and is slidably connected to the guide rods through the through holes. A return spring is sleeved on the guide rod between the second slot block and the fixed baffle. The bottom of the second slot block has a strip-shaped groove. One end of the strip-shaped groove near the discharge slot block is open and located near the return spring, while the other end is located near the first slot block. A fixed block is provided on the frame on the side of the discharge slot block. A protruding post is provided at the top of the fixed block. The protruding post can slide into the strip-shaped groove when the second slot block approaches.

[0007] Using the above technical solution, the driving mechanism drives the fixed base plate and the feeding trough block to slide towards the discharging trough block, so that the strip groove at the bottom of the second trough block cooperates with the protrusion on the fixed block. This allows the second trough block to move away from the first trough block and squeeze the return spring, ultimately allowing the bar stock to fall into the discharging trough block. Then, as the driving mechanism drives the fixed base plate back, under the elastic force of the return spring, the second trough block moves closer to and fits against the first trough block again, thus completing one feeding process. This feeding method can avoid wear caused by the bar stock sliding in the trough, improve the surface quality of the bar stock, and reduce the defect rate. At the same time, the shifting mechanism can transfer the bar stock in the storage trough to the feeding trough block, completing automatic feeding.

[0008] A further provision of the above technical solution is that the upper ends of the first groove block and the second groove block are provided with triangular grooves on one side close to each other, and when the first groove block and the second groove block are fitted together, the two triangular grooves form a V-shaped groove that can support the bar material.

[0009] Using the above technical solution, the V-shaped groove can stably support the bar stock, ensuring that the bar stock is in a stable position within the feeding trough, avoiding bar stock deviation during the transfer process, and ensuring feeding accuracy.

[0010] A further provision of the above technical solution is that: the upper end of the feeding trough block is provided with a V-shaped groove, and the feeding trough block is provided with a U-shaped groove in the middle of the V-shaped groove to facilitate gripping by the main shaft of the Swiss-type machine.

[0011] Using the above technical solution, the V-shaped groove can position the falling bar stock, while the U-shaped groove provides space for the Swiss-type headstock spindle to grip the bar stock, making it easier for the spindle to grip the bar stock quickly and accurately, thus improving feeding efficiency.

[0012] A further provision of the above technical solution is that: both the fixed baffle and the second slot block are provided with recessed grooves on the side near the reset spring, and the two ends of the reset spring respectively abut against the bottom of the corresponding recessed groove.

[0013] By adopting the above technical solution, the sink can position the return spring, improve the stability of the return spring during the extension and contraction process, and save assembly space.

[0014] A further configuration of the above technical solution is as follows: the driving mechanism includes a linear guide rail and a first cylinder fixedly mounted on the frame, the slider of the linear guide rail is fixedly connected to a fixed baffle, and the movable end of the first cylinder is fixedly connected to the fixed baffle.

[0015] By adopting the above technical solution, the linear guide rail can ensure the stability and straightness of the sliding of the fixed base plate, and the first cylinder can provide a stable driving force to drive the feeding trough block to slide accurately, ensuring the matching accuracy of the protrusion and the strip groove, and improving the operating stability of the device.

[0016] A further configuration of the above technical solution is as follows: the shifting mechanism includes a shifting seat mounted on the frame, a second cylinder mounted on the shifting seat, and a shifting block that can slide perpendicularly to the feeding trough block on the shifting seat. The movable end of the second cylinder is fixedly connected to the shifting block. The hopper is fixedly mounted on the shifting seat. The shifting block is provided with a receiving groove that cooperates with the bar stock. The receiving groove has a first position communicating with the storage trough and a second position located directly above the feeding trough block.

[0017] Using the above technical solution, the second cylinder drives the shifting block to slide, so that the receiving trough receives the bar material falling from the storage trough at the first position, and then moves to the second position to send the bar material to the feeding trough block, thereby realizing the precise transfer of the bar material from the storage trough to the feeding trough block and ensuring the continuity of automatic feeding.

[0018] A further provision of the above technical solution is that: a protective cover is provided around the upper edge of the frame, an observation window is provided on the side plate of the protective cover facing the operator, and an avoidance opening is provided on the side of the material discharge trough block of the protective cover.

[0019] By adopting the above technical solution, the observation window allows operators to observe the feeding situation inside the device in real time, and promptly detect and handle abnormal problems; the clearance opening can prevent the protective cover from blocking the fixed base plate and feeding trough block, as well as from hindering the main shaft of the Swiss-type machine from grabbing the bar stock on the feeding trough block, ensuring the smooth progress of the feeding process.

[0020] The beneficial effects achieved by this utility model are: by splitting the feeding trough block into a first trough block and a second trough block, and with the help of the driving mechanism, the protrusion and the strip groove, the two trough blocks are separated, allowing the bar stock to fall directly into the discharge trough block, avoiding sliding friction between the bar stock and the feeding trough block, improving the surface quality of the bar stock and reducing the defect rate.

The two ends of the second trough block 22 are provided with through holes and are slidably connected to the guide rods 7 through the through holes. A return spring 8 is sleeved between the guide rod 7 and the second groove block 22 and the fixed baffle 6. The bottom of the second groove block 22 is provided with a strip groove 221. One end of the strip groove 221 near the material feeding trough block 4 is open and located near the return spring 8, while the other end is located near the first groove block 21. A fixing block 9 is provided on the frame 1 on one side of the material feeding trough block 4. The top of the fixing block 9 is provided with a protrusion 91. The protrusion 91 can slide into the strip groove 221 when the second groove block 22 approaches. like Figure 2-4 As shown, the upper ends of the first groove block 21 and the second groove block 22 are both provided with triangular grooves on one side close to each other. When the first groove block 21 and the second groove block 22 are fitted together, the two triangular grooves form a V-shaped groove that can support the bar stock. The upper end of the feeding groove block 4 is provided with a V-shaped groove 41, and the feeding groove block 4 is provided with a U-shaped groove 42 in the middle of the V-shaped groove 41 to facilitate the gripping of the Swiss-type headstock spindle. like Figure 2 , 4 As shown, both the fixed baffle 6 and the second slot block 22 have recesses 61 on their sides near the return spring 8, and the two ends of the return spring 8 abut against the bottom of the corresponding recesses 61. The drive mechanism 10 includes a linear guide rail 101 and a first cylinder 102 fixedly mounted on the frame 1. The slider of the linear guide rail 101 is fixedly connected to the fixed baffle 6, and the movable end of the first cylinder 102 is fixedly connected to the fixed baffle 6. like Figure 2 , 6As shown, the shifting mechanism 11 includes a shifting seat 111 mounted on the frame 1, a second cylinder 112 mounted on the shifting seat 111, and a shifting block 113 that can slide perpendicularly to the feeding trough block 2 on the shifting seat 111. The movable end of the second cylinder 112 is fixedly connected to the shifting block 113. The hopper 3 is fixedly mounted on the shifting seat 111. The shifting block 113 is provided with a receiving groove 1131 that cooperates with the bar stock.

The second cylinder 112 drives the shifting block 113 to slide to the second position, sending the bar stock into the V-shaped groove formed by the first groove block 21 and the second groove block 22. Then, the first cylinder 102 drives the fixed base plate 5 and the feeding groove block 2 to slide towards the unloading groove block 4. When the second groove block 21... When the bar stock approaches the fixed block 9, the protrusion 91 slides into the strip groove 221, forcing the second groove block 22 to move along the guide rod 7 towards the fixed baffle 6, separating from the first groove block 21, until the bar stock falls into the V-shaped recess 41 of the feeding groove block 4; the Swiss-type headstock spindle grabs the bar stock through the U-shaped groove 42, completing the feeding, the first cylinder 102 drives the fixed base plate 5 to reset, and the reset spring 8 pushes the second groove block 22 to reset, re-fitting with the first groove block 21, waiting for the next feeding. The whole process avoids sliding friction between the bar stock and the feeding groove block 2, improves the surface quality of the bar stock, and reduces the defect rate.
