Description

Technical Field

[0001] The invention relates to the technical field of lathe unloading, and in particular to a material loosening device for lathe processing. Background Art

[0002] A spindle box is installed on the bed of the lathe, and a tooling for clamping the workpiece is installed on the spindle box. The spindle box can drive the tooling for clamping the workpiece to rotate. A slide plate for supporting the tool is also installed on the bed, and the slide plate can slide on the bed.

[0003] The workpiece and the tooling are assembled by threaded fitting. After cutting the workpiece, the staff needs to manually loosen the workpiece from the tooling to realize the loosening operation, and then the robot takes away the loosened workpiece to realize the unloading operation.

[0004] During the process of cutting the workpiece, the tool will constantly push against the workpiece, deepening the depth of the workpiece screwed into the tooling, making the thread tighter and tighter. It is difficult for the staff to loosen the workpiece, which increases the difficulty of loosening the material, thereby reducing the efficiency of loosening the material and then reducing the unloading efficiency. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a material loosening device for lathe processing, which can replace manual material loosening operations, reduce the difficulty of material loosening, and improve the material loosening efficiency and unloading efficiency.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A material loosening device for lathe processing comprises a mounting plate, an elastic buffer, a movable frame, a telescopic member, a push-pull block, a claw and an elastic member. An elastic buffer is arranged at one end of the mounting plate, a movable frame is arranged at an end of the mounting plate away from the elastic buffer, the movable frame is slidably connected with the mounting plate, the movable frame slides in a direction approaching the elastic buffer or away from the elastic buffer, the movable frame cooperates with the elastic buffer, a telescopic member is arranged at an end of the movable frame away from the elastic buffer, two push-pull blocks arranged side by side are arranged at the lower end of the telescopic member, two claws are arranged between the two push-pull blocks, the upper ends of the two claws are rotatably connected with the moving frame, the upper ends of the two claws are provided with elastic members for separating the two claws, the push-pull block is provided with a convex portion on a side close to the claw, and the convex portion cooperates with the claw.

[0008] Furthermore, the mounting plate is provided with a guide rail, the guide rail is provided with a slider, and the slider is connected to the movable frame.

[0009] Furthermore, the mounting plate is provided with a limit block, which is arranged between the elastic buffer and the moving frame. The elastic buffer is provided with a collision block at one end close to the moving frame, and the collision block cooperates with the limit block.

[0010] Furthermore, a pad is provided between the sliding block and the moving frame.

[0011] Furthermore, the movable frame is provided with a slide groove on a side away from the elastic buffer member, and the telescopic member, the two push-pull blocks, the two clamping claws and the elastic member are all arranged in the slide groove.

[0012] Furthermore, a connecting block is provided at the lower end of the telescopic member, a dovetail groove is provided at the lower end of the connecting block, and the dovetail groove cooperates with the upper end of the push-pull block.

[0013] Furthermore, the movable frame is provided with a pressure plate for shielding the middle part of the slide slot, and the two push-pull blocks, the two clamping claws, and the elastic member are all arranged between the pressure plate and the bottom of the slide slot.

[0014] Furthermore, the claw is provided with anti-slip grooves on a side away from the push-pull block.

[0015] The present invention has the beneficial effects:

[0016] 1. Compared with the background technology, the present invention can use machinery to replace manual loosening operations, which not only reduces the labor intensity of the staff, but also reduces the difficulty of loosening, improves the loosening efficiency, and then improves the unloading efficiency. In addition, the present invention is particularly suitable for loosening small shaft parts.

[0017] 2. The present invention provides guide rails and sliders, and the movable frame can be installed on the mounting plate by simply sliding the slider onto the guide rails, and the movable frame and the mounting plate can be disassembled by simply sliding the slider off the guide rails, making the disassembly and assembly operation of the movable frame to the mounting plate simple and quick, thereby improving the maintenance efficiency of the present invention.

[0018] 3. By arranging a collision block for colliding with the limit block on the elastic buffer, the present invention increases the collision area on the one hand, thereby improving the reliability of the collision, compared with the direct collision of the elastic buffer with the limit block, and on the other hand, avoids the elastic buffer from being directly damaged by the collision impact, thereby protecting the elastic buffer, reducing the cost of replacing the elastic buffer, saving the time spent on the replacement operation, and further improving the material loosening efficiency and unloading efficiency.

[0019] 4. The present invention can increase the distance between the movable frame and the mounting plate by arranging a pad between the slider and the movable frame, thereby providing sufficient space to accommodate limit blocks and collision blocks of different thicknesses, thereby improving the use flexibility of the present invention, so as to make the present invention more popular with users.

[0020] 5. The present invention sets a slide groove on the movable frame, and sets the telescopic member, two push-pull blocks, two claws, and elastic member in the slide groove. On the one hand, the present invention can make the structure compact and reduce the space on the lathe occupied by the present invention, so that the staff has more space to operate the lathe. On the other hand, when the telescopic member is extended and retracted to slide the push-pull block up and down, the side of the push-pull block away from the claw is blocked by the groove wall of the slide groove, so as to avoid the lower end of the push-pull block from tilting to the side away from the claw, thereby ensuring the stability of the push-pull block sliding in the vertical direction, thereby further improving the material loosening efficiency and unloading efficiency. Because once the lower end of the push-pull block tilts to the side away from the claw, the lower end of the push-pull block cannot clamp the claw, so that the claw cannot grasp the workpiece, and the workpiece cannot be screwed. At this time, the staff needs to loosen the material manually, which prolongs the time consumption of the loosening operation and reduces the material loosening efficiency and unloading efficiency.

[0021] 6. The present invention provides a dovetail groove for cooperating with the push-pull block on the connecting block at the lower end of the telescopic member. The push-pull block can be installed by simply inserting the upper end of the push-pull block into the dovetail groove, and the push-pull block can be disassembled by simply pulling the upper end of the push-pull block out of the dovetail groove, which makes the disassembly and assembly of the push-pull block simple and quick, and improves the efficiency of maintenance work.

[0022] 7. The present invention provides a pressure plate, which, on the one hand, can prevent the claws, push-pull blocks, and elastic parts from being completely exposed, thereby improving the aesthetics; on the other hand, it can limit the push-pull block and prevent it from falling out of the dovetail groove, thereby improving the reliability of the cooperation between the push-pull block and the dovetail groove and reducing the risk of the push-pull block falling out of the dovetail groove, thereby saving time and eliminating the need to stop the machine to reinsert the push-pull block that has fallen out of the dovetail groove into the dovetail groove, thereby further improving the material loosening efficiency and unloading efficiency.

[0023] 8. The present invention can increase the resistance between the clamping jaw and the workpiece by arranging anti-slip grooves on the clamping jaw, thereby improving the firmness and reliability of the clamping jaw in clamping the workpiece, reducing the probability of the workpiece being unable to be screwed and subsequently unable to be loosened due to the clamping jaw not being able to firmly grasp the workpiece, thereby ensuring the reliability of the loosening operation.

[0032] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0033] Example:

[0034] like Figure 1-6 As shown, a material loosening device for lathe processing includes a mounting plate 1, an elastic buffer, a movable frame 4, a telescopic member, a push-pull block 13, a clamping claw 14, and an elastic member.

[0035] In order to facilitate the material collection, the elastic buffer is used as a buffer. Figure 3 and Figure 6 As shown, a buffer bracket 2 is fixed to one end of the mounting plate 1 by bolts, and a buffer 3 is mounted on the buffer bracket 2 .

[0036] like Figure 3 and Figure 4 As shown, a movable frame 4 is provided at one end of the mounting plate 1 away from the buffer 3 , and the movable frame 4 is slidably connected to the mounting plate 1 , and the movable frame 4 can slide in a direction close to the buffer 3 or away from the buffer 3 .

[0037] Specifically, Figure 6As shown, the mounting plate 1 is fixed with two guide rails 5 arranged side by side by bolts, and a slider 6 is installed on the guide rail 5. Figure 5 As shown, the two sliders 6 are fixed with a backing plate 7 by screws. Figure 1 As shown, the backing plate 7 is fixed to the moving frame 4 by screws on the side away from the slider 6. When the moving frame 4 slides in the direction close to the buffer 3, the slider 6 can slide along the guide rail 5 in the direction close to the buffer 3; when the moving frame 4 slides in the direction away from the buffer 3, the slider 6 can slide along the guide rail 5 in the direction away from the buffer 3.

[0038] By setting the guide rail 5 and the slider 6, the movable frame 4 can be installed on the mounting plate 1 by simply sliding the slider 6 onto the guide rail 5, and the movable frame 4 and the mounting plate 1 can be disassembled by simply sliding the slider 6 off the guide rail 5, so that the disassembly and assembly operation of the movable frame 4 to the mounting plate 1 is simple and quick, thereby improving the maintenance efficiency.

[0039] like Figure 6 As shown, the mounting plate 1 is fixed with a limit block 8 by bolts, and the limit block 8 is not only arranged between the buffer 3 and the moving frame 4, but also arranged between the two guide rails 5. The buffer 3 is provided with a collision block 9 at one end close to the moving frame 4.

[0040] By setting the limit block 8 and the impact block 9, compared with the direct collision of the buffer 3 with the limit block 8, on the one hand, the collision area is increased, thereby improving the reliability of the collision. On the other hand, the buffer 3 is prevented from being damaged by direct collision impact, which plays a role in protecting the buffer 3. Not only the cost of replacing the buffer 3 is reduced, but also the time consumed in the replacement operation is saved.

[0041] By setting a pad 7 between the slider 6 and the movable frame 4, the distance between the movable frame 4 and the mounting plate 1 can be increased, thereby providing sufficient space to accommodate the limit blocks 8 and the impact blocks 9 of different thicknesses, thereby improving the flexibility of use and making it more popular with users.

[0042] like Figure 2 As shown, the moving frame 4 is provided with a slide groove 401 on a side away from the buffer 3. The telescopic member adopts a cylinder 10, and a cylinder mounting seat 11 is fixed to the upper end of the cylinder 10 by bolts. The cylinder mounting seat 11 is fixed in the slide groove 401 by bolts, and the cylinder 10 is also arranged in the slide groove 401.

[0043] By providing the slide groove 401, the structure can be made compact and the space occupied on the lathe can be reduced, thereby allowing the staff to have more space to operate the lathe.

[0044] like Figure 2As shown, the lower end of the piston rod of the cylinder 10 is fixed with a connecting block 12 by bolts, and the connecting block 12 is also arranged in the slide groove 401, and two dovetail grooves 1201 are arranged at the lower end of the connecting block 12. Two push-pull blocks 13 arranged side by side are arranged below the connecting block 12, and the upper ends of the push-pull blocks 13 are inserted in the dovetail grooves 1201, and the two push-pull blocks 13 are also arranged in the slide groove 401.

[0045] By setting a dovetail groove 1201 on the connecting block 12 for cooperating with the push-pull block 13, the installation of the push-pull block 13 can be completed by simply inserting the upper end of the push-pull block 13 into the dovetail groove 1201, and the disassembly of the push-pull block 13 can be completed by simply pulling the upper end of the push-pull block 13 out of the dovetail groove 1201, so that the disassembly and assembly operation of the push-pull block 13 is simple and quick, and the efficiency of maintenance work is improved.

[0046] like Figure 2 As shown, two claws 14 are arranged between the two push-pull blocks 13, and the two claws 14 are arranged in the slide slot 401. The upper ends of the two claws 14 are sleeved on the same axle pin 15, and the axle pin 15 is fixed on the mobile frame 4. This axle pin 15 is the rotation center of the two claws 14. An elastic member (not shown in the figure) is used to separate the two claws 14. The elastic member is arranged in the slide slot 401. The elastic member can be a spring sheet, a torsion spring, or a spring. When the elastic member is a spring, one end of the spring is welded and fixed to the upper end of one claw 14, and the other end of the spring is welded and fixed to the upper end of the other claw 14.

[0047] like Figure 2 As shown, the push-pull block 13 is provided with a convex portion 1301 on a side close to the clamping claw 14. The clamping claw 14 is provided with an anti-slip groove 1401 on a side away from the push-pull block 13. By providing the anti-slip groove 1401 on the clamping claw 14, the resistance between the clamping claw 14 and the workpiece can be increased, thereby improving the firmness and reliability of the clamping claw 14 clamping the workpiece, reducing the probability of the workpiece being unable to be screwed due to the clamping claw 14 not firmly grasping the workpiece, and then being unable to loosen the material, thereby ensuring the reliability of the loosening operation.

[0048] like Figure 1 As shown, the mobile frame 4 is provided with a pressing plate 16 for shielding the middle part of the slide slot 401, and the pressing plate 16 is fixed to the mobile frame 4 by bolts. Two push-pull blocks 13, two claws 14, and elastic members are all arranged between the pressing plate 16 and the bottom of the slide slot 401.

[0049] By setting the pressure plate 16, on the one hand, it is possible to prevent the claws 14, the push-pull block 13, and the elastic member from being completely exposed, thereby improving the aesthetics; on the other hand, it is possible to limit the push-pull block 13 and prevent the push-pull block 13 from escaping from the dovetail groove 1201, thereby improving the reliability of the cooperation between the push-pull block 13 and the dovetail groove 1201 and reducing the risk of the push-pull block 13 escaping from the dovetail groove 1201, thereby saving time and eliminating the need to stop the machine to reinsert the push-pull block 13 that has escaped from the dovetail groove 1201 into the dovetail groove 1201.

[0050] When using a material loosening device for lathe processing in this embodiment, it is necessary to install the mounting plate 1 on the slide on the lathe bed by screws, and let the side of the movable frame 4 away from the buffer 3 face the tooling for clamping the workpiece on the lathe bed, taking a rod with an external thread as an example of the workpiece.

[0051] The operation process of the material loosening device for lathe processing of the present embodiment is as follows: first, after the workpiece is processed, the slide board carries the material loosening device for lathe processing of the present embodiment and approaches the position of the tooling that clamps the workpiece, so as to facilitate the delivery of the material loosening device for lathe processing on the slide board to the clamping position of the workpiece, that is, the position where the workpiece is inserted between the two claws 14.

[0052] Then, the piston rod of the cylinder 10 is pushed downward, the piston rod of the cylinder 10 pushes the connecting block 12 downward, the connecting block 12 pushes the two push-pull blocks 13 downward, and the protrusions 1301 on the two push-pull blocks 13 also move downward. In the process of the protrusions 1301 moving downward, the protrusions 1301 on the two push-pull rods can gradually squeeze the two claws 14 located between the two push-pull blocks 13, so that the lower ends of the claws 14 are close to each other to clamp the workpiece.

[0053] Secondly, the spindle in the spindle box on the lathe used to drive the tooling to rotate is reversed, and the workpiece thread is gradually loosened. During the process of the workpiece thread being gradually loosened, since the workpiece is clamped by two claws 14, the workpiece gradually moves away from the spindle box during the reversal of the spindle in the spindle box, causing the movable frame 4 to also move away from the spindle box and continuously compress the buffer 3. After the workpiece thread is loosened, the spindle in the spindle box stops reversing, thereby completing the material loosening operation.

[0054] Then, the piston rod of the cylinder 10 retracts, and the piston rod of the cylinder 10 moves up with the connecting block 12, and the connecting block 12 moves up with the two push-pull blocks 13, and the protrusions 1301 on the two push-pull blocks 13 move up. In the process of the protrusion 1301 moving up, the protrusion 1301 no longer squeezes the claws 14. Under the elastic force of the elastic member, the two claws 14 resume their open state. Since the spindle in the spindle box no longer reverses, the workpiece is not subjected to the axial thrust of the thread. At this time, the buffer 3 starts to work, and the buffer 3 pushes the movable frame 4 in the direction close to the workpiece until the collision block 9 collides with the limit block 8. At this time, a material loosening device for lathe processing in this embodiment is restored to its initial state.

[0055] Finally, the robot can take away the workpiece that has completed the feeding operation.

[0056] Through the above process, it can be known that the material loosening device for lathe processing of the present embodiment can use machinery to replace manual material loosening operations, which not only reduces the labor intensity of the staff, but also reduces the difficulty of loosening materials, improves the loosening efficiency, and then improves the unloading efficiency. In addition, since the size of the workpiece that can be clamped by the two claws 14 is limited, the material loosening device for lathe processing of the present embodiment is particularly suitable for loosening small shaft parts.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
