Description

Technical Field

[0001] This application relates to the field of cam machine tool technology, and in particular to a cam machine tool loading rack. Background Technology

[0002] A cam-driven machine tool is a high-efficiency machining equipment with a cam mechanism as its core transmission device. With its precise motion control and stable machining performance, it is widely used in the field of mechanical manufacturing. It can complete the high-precision machining of complex parts and provide high-quality parts for various industries.

[0003] In the past, when machining parts on cam-type machine tools, it was often necessary to manually feed the strip-shaped workpiece. The operator had to hold the strip-shaped workpiece by hand and gradually feed it into the machine tool. Throughout the entire machining process, the operator had to pay close attention and operate manually to ensure that the workpiece could be smoothly fed into the machine tool and completed the machining.

[0004] When loading onto existing cam-type machine tools, manual limb movements are repeatedly used, which can easily lead to fatigue during long-term operation and reduce loading efficiency. Furthermore, when loading strip-shaped workpieces by hand, there is a lack of effective guiding devices. When the operator applies force with their hands, the workpiece is prone to positional deviation during the transfer process, affecting the loading accuracy. Utility Model Content

[0005] The purpose of this application is to address the problems mentioned in the background art, such as the reliance on repetitive manual limb movements for manual feeding, which can easily lead to fatigue during long-term operation, and the tendency for the workpiece to shift position during the conveying process when manually feeding strip-shaped workpieces, thus affecting the feeding accuracy. This application provides a cam-type machine tool feeder.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A cam-type machine tool feeder includes a support rod, a connecting block rotatably connected to the upper end of the support rod, a feed tube fixed to the upper end of the connecting block, a support frame provided at the end of the feed tube away from the connecting block, a sliding groove formed on the surface of the feed tube, a sliding block slidably disposed inside the sliding groove, a sliding seat fixed to the lower end of the sliding block, the sliding seat slidably disposed inside the feed tube, a connecting groove formed on the side of the sliding seat, a limit rod fixed on the feed tube, a pushing structure provided between the sliding block and the support frame, and a fixing structure provided between the feed tube and the support frame.

[0008] By adopting the above technical solution, when using the feeding rack, the strip-shaped workpiece is placed inside the feeding tube, and then the pushing structure pushes the strip-shaped workpiece into the cam machine tool. As the cam machine tool processes the strip-shaped workpiece, the strip-shaped workpiece is gradually fed into the cam machine tool, completing the feeding.

[0009] Furthermore, the sliding seat surface is rotatably connected with circumferentially distributed balls, and the surface of the balls is in contact with the inner wall of the feeding tube.

[0010] By adopting the above technical solution, when the sliding seat slides inside the feeding tube, the ball rotates, which can reduce the friction between the sliding seat and the feeding tube, thereby making the sliding seat slide more smoothly.

[0011] Furthermore, the pushing structure includes a hook disposed on the sliding block, the sliding block having a connecting hole, the hook being slidably inserted into the connecting hole, and a first connecting line being fixed to the end of the hook away from the sliding block.

[0012] By adopting the above technical solution, by pulling the first connecting line, the sliding block is pulled, causing the sliding block to slide inside the feeding tube, thereby driving the long strip-shaped workpiece into the cam machine tool to achieve feeding.

[0013] Furthermore, a first take-up roller is installed on the upper end of the support frame, and the end of the first connecting line away from the hook is fixedly connected to the first take-up roller.

[0014] By adopting the above technical solution, the first take-up wheel can wind up the first connecting line, and by winding up the first connecting line, the sliding block can be pulled.

[0015] Furthermore, a second take-up roller is rotatably connected to the upper end of the support frame away from the first take-up roller, and the second take-up roller passes through the support frame and is fixedly connected to the second take-up roller.

[0016] By adopting the above technical solution, the second take-up roller rotates, driving the first take-up roller, thereby providing power for the first take-up roller to wind up the first connecting wire.

[0017] Furthermore, a second connecting line is fixed on the first take-up roller, and a counterweight is fixed at the end of the second connecting line away from the second take-up roller.

[0018] By adopting the above technical solution, when the sliding block is pulled to put the strip-shaped workpiece into the upper feed tube, the first connecting line wound on the first take-up roller gradually separates from the first take-up roller, causing the first take-up roller to rotate. When the first take-up roller rotates, it drives the second take-up roller to rotate, so that the second take-up roller winds up the second connecting line. When the cam machine tool starts to process the workpiece, the workpiece gradually enters the cam machine tool. At this time, under the action of the weight of the counterweight, the second connecting line gradually separates from the second take-up roller. At this time, the second take-up roller rotates, driving the first take-up roller to rotate, thereby winding up the first connecting line and realizing the feeding of material into the cam machine tool.

[0019] Furthermore, the fixing structure includes a support base fixed to the side of the support frame, a first snap-fit ​​block fixed on the support base, a second snap-fit ​​block installed on the side of the first snap-fit ​​block, and the end of the feeding pipe extending between the second snap-fit ​​block and the second snap-fit ​​block.

[0020] By adopting the above technical solution, the first snap-fit ​​block, together with the second snap-fit ​​block, can fix the end of the feeding tube, enabling it to feed materials.

[0021] Furthermore, a fixing block is fixed to the side of the second snap-fit ​​block, an adjustment groove is provided on the support base, a fixing post is slidably provided on the second snap-fit ​​block, the fixing post slides through the second snap-fit ​​block and the adjustment groove, a fixing sleeve is threaded to the lower end of the fixing post, and the upper end of the fixing sleeve is in contact with the lower end of the support base.

[0022] By adopting the above technical solution, when placing the strip-shaped workpiece into the feed tube, the fixing sleeve is loosened so that it is no longer in contact with the support seat. Then the second connecting block can be slid to separate the second connecting block from the feed tube. Then the feed tube is rotated to make the feed tube misaligned with the cam machine tool. Then the strip-shaped workpiece can be placed into the feed tube.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, the feeding structure, during feeding, places the strip-shaped workpiece inside the feeding tube. Under the weight of the counterweight, it pulls the second connecting line, causing the second take-up roller to rotate. The rotation of the second take-up roller drives the first take-up roller to rotate, and the first take-up roller rotates to wind up the first connecting line. During the winding process, the first connecting line pulls the sliding block and sliding seat to move, thereby pushing the strip-shaped workpiece gradually into the cam machine tool, realizing feeding. When feeding, the feeding rack can achieve automatic feeding without the operator's manual support, greatly reducing the workload; it has a good guiding function, which can effectively reduce the deviation problem caused by holding the strip-shaped workpiece during feeding; and the feeding speed can be automatically adjusted according to the processing speed, which significantly improves the convenience of operation.

[0031] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0032] This application discloses a cam-type machine tool feeder.

[0033] Reference Figure 1 A cam-mounted machine tool feeder includes a support rod 1, with a connecting block 11 rotatably connected to the upper end of the support rod 1. A feed pipe 12 is fixed to the upper end of the connecting block 11. A support frame 13 is provided at the end of the feed pipe 12 away from the connecting block 11. Both the support rod 1 and the support frame 13 are height-adjustable, thus making the feeder suitable for cam-mounted machines of different heights. A sliding groove 14 is provided on the surface of the feed pipe 12. A sliding block 15 is slidably disposed inside the sliding groove 14. A sliding seat 16 is fixed to the lower end of the sliding block 15. The sliding seat 16 is slidably disposed inside the feed pipe 12. A connecting groove 17 is provided on the side of the sliding seat 16. A limit rod 4 is fixed on the feed pipe 12. When the sliding block 15 and the sliding seat 16 slide to the end close to the support frame 13, the limit rod 4 can restrict the sliding block 15 to prevent it from sliding onto the feed pipe 12. A pushing structure is provided between the sliding block 15 and the support frame 13, and a fixing structure is provided between the feed pipe 12 and the support frame 13.

[0034] When using the feeding rack, the feeding rack is aligned with the feed port of the cam machine tool. During feeding, the strip-shaped workpiece is placed into the feeding tube 12, and then the pushing structure pushes the strip-shaped workpiece into the cam machine tool. As the cam machine tool processes the strip-shaped workpiece, the strip-shaped workpiece is gradually fed into the cam machine tool.

[0035] Reference Figure 2 The sliding seat 16 is rotatably connected to a ball bearing 18 that is evenly distributed in the circumferential direction, and the surface of the ball bearing 18 is in contact with the inner wall of the feed tube 12.

[0036] During the feeding process, the sliding seat 16 slides inside the feeding tube 12. At this time, the ball bearing 18 rotates. The rotation of the ball bearing 18 reduces the friction between the sliding seat 16 and the feeding tube 12, making the sliding seat 16 slide more smoothly and thus facilitating the feeding of materials into the cam machine tool.

[0037] Reference Figure 1 , Figure 2 , Figure 4 The push structure includes a hook 2 set on the sliding block 15. The sliding block 15 has a connection hole 19. The hook 2 is slidably inserted into the connection hole 19. The end of the hook 2 away from the sliding block 15 is fixed with a first connecting line 21.

[0038] The support frame 13 has a first take-up roller 22 installed on its upper end, and the end of the first connecting line 21 away from the hook 2 is fixedly connected to the first take-up roller 22.

[0039] In addition, a second take-up roller 23 is rotatably connected to the upper end of the support frame 13 away from the first take-up roller 22. The second take-up roller 23 passes through the support frame 13 and is fixedly connected to the second take-up roller 23.

[0040] Furthermore, a second connecting line 24 is fixed on the first take-up roller 22, and a counterweight 25 is fixed at the end of the second connecting line 24 away from the second take-up roller 23.

[0041] After the strip-shaped workpiece is placed into the feed tube 12, the workpiece is pushed, causing the sliding seat 16 to move. As the sliding seat 16 moves, the sliding block 15 moves accordingly and pulls the first connecting wire 21, causing the first connecting wire 21 to no longer be wound on the first take-up roller 22. This pulls the first take-up roller 22, causing it to rotate. When the first take-up roller 22 rotates, it drives the second take-up roller 23 to rotate. When the second take-up roller 23 rotates, it winds up the second connecting wire 24 and pulls the counterweight 25 upward. Once the strip-shaped workpiece is completely inside the feed tube 12, it moves away from the sliding seat 1. One end of 6 is connected to the feed port of the cam machine tool, and then processing begins. During processing, the counterweight 25 pulls the second connecting line 24, causing the second take-up roller 23 to rotate. When the second take-up roller 23 rotates, it drives the first take-up roller 22 to rotate. The first take-up roller 22 rotates to wind up the first connecting line 21. During the winding process, the first connecting line 21 pulls the sliding block 15 and the sliding seat 16 to move, thereby pushing the strip-shaped workpiece into the cam machine tool to achieve feeding. Feeding can be achieved without the operator's manual support, and the feeding speed can adapt to the processing speed.

[0042] Reference Figure 1 and Figure 4The fixing structure includes a support base 3 fixed to the side of the support frame 13, a first snap-fit ​​block 31 fixed on the support base 3, a second snap-fit ​​block 32 installed on the side of the first snap-fit ​​block 31, and the end of the feeding pipe 12 extending into the space between the second snap-fit ​​block 32 and the second snap-fit ​​block 32.

[0043] The second snap-fit ​​block 32 has a fixing block 33 fixed on its side, and the support base 3 has an adjustment groove 35. A fixing post 34 is slidably arranged on the second snap-fit ​​block 32. The fixing post 34 slides through the second snap-fit ​​block 32 and the adjustment groove 35. A fixing sleeve 36 is threadedly connected to the lower end of the fixing post 34. The upper end of the fixing sleeve 36 is in contact with the lower end of the support base 3.

[0044] When it is necessary to put the strip-shaped workpiece to be processed into the feed tube 12, loosen the fixing sleeve 36 so that the fixing sleeve 36 no longer abuts against the support seat 3, then pull the second clamping block 32 so that it slides to the end of the support seat 3, so that the second clamping block 32 separates from the feed tube 12 and no longer restricts the feed tube 12. Then rotate the feed tube 12 so that its end no longer corresponds to the cam machine tool, and then it is convenient to feed the strip-shaped workpiece into the feed tube 12. After feeding, reset the feed tube 12 so that it contacts the first clamping block 31, and then push the second clamping block 32 so that the second clamping block 32 cooperates with the first clamping block 31 to clamp and restrict the feed tube 12. Then tighten the fixing sleeve 36 so that the fixing sleeve 36 abuts against the lower end of the support seat, thereby fixing the second clamping block 32 and completing the feeding of the strip-shaped workpiece into the feed tube 12.

[0045] Working principle: When in use, the feeding rack is aligned with the feed inlet of the cam machine tool. When feeding, the strip-shaped workpiece needs to be placed into the feeding tube 12. When placing it, loosen the fixing sleeve 36 so that the fixing sleeve 36 no longer abuts against the support seat 3. Then pull the second locking block 32 so that it slides to the end of the support seat 3, so that the second locking block 32 separates from the feeding tube 12 and no longer restricts the feeding tube 12. Then rotate the feeding tube 12 so that its end no longer corresponds to the cam machine tool. Then it is easy to send the strip-shaped workpiece into the feeding tube 12. After sending it in, reset the feeding tube 12 so that it contacts the first locking block 31. Then push the second locking block 32 so that the second locking block 32 cooperates with the first locking block 31 to clamp and restrict the feeding tube 12. Then tighten the fixing sleeve 36 so that the fixing sleeve 36 abuts against the lower end of the support seat, thereby fixing the second locking block 32 and completing the placement of the strip-shaped workpiece.

[0046] Then, the strip-shaped workpiece is pushed, causing the sliding seat 16 to move. As the sliding seat 16 moves, the sliding block 15 moves accordingly and pulls the first connecting wire 21, causing the first connecting wire 21 to no longer be wound on the first take-up roller 22. This pulls the first take-up roller 22, causing it to rotate. When the first take-up roller 22 rotates, it drives the second take-up roller 23 to rotate. When the second take-up roller 23 rotates, it winds up the second connecting wire 24 and pulls the counterweight 25 upward. When the strip-shaped workpiece is completely inside the feeding pipe 12, the strip-shaped workpiece... The end of the workpiece away from the sliding seat 16 is connected to the feed port of the cam machine tool, and then processing begins. During processing, the counterweight 25 pulls the second connecting line 24, causing the second take-up roller 23 to rotate. When the second take-up roller 23 rotates, it drives the first take-up roller 22 to rotate. The first take-up roller 22 rotates to wind up the first connecting line 21. During the winding process, the first connecting line 21 pulls the sliding block 15 and the sliding seat 16 to move, thereby pushing the strip-shaped workpiece gradually into the cam machine tool to achieve feeding.
