Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a guide device for unloading grooves. Background Technology

[0002] When machining unloading grooves on workpieces using machine tools, the shift fork is used for positioning. However, it can only achieve positioning during the machining process, but cannot prevent errors in machining direction, and cannot improve the situation where the tool breaks due to the workpiece being placed in the wrong direction during machining.

[0003] Both the workpiece pin hole center and the workpiece center are eccentric. Based on this principle, we changed the way the machine tool tailstock is connected by a guide rod. During the workpiece clamping process, the guide rod prevents the workpiece from being placed in reverse. By modifying the tailstock of the equipment and adding a guide and error-proof device, we can overcome the problem of workpiece defects caused by reverse workpiece placement during processing, thus achieving the purpose of error prevention and increasing the tool life. Utility Model Content

[0004] This utility model discloses an unloading groove guiding device, which aims to solve the technical problem that the workpiece is easily placed backwards when processing the unloading groove.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A unloading groove guide device includes a base plate, a guide base slidably disposed on the front side of the base plate, a through movable hole opened on the side of the guide base, and an anti-reverse component inserted into the inner wall of the through movable hole. The anti-reverse component is used to detect the workpiece in reverse.

[0007] The anti-reverse component includes a guide sleeve, a guide rod is inserted and installed at the left end of the guide sleeve, the guide rod is used to insert into the workpiece pin hole, the surface of the guide rod is provided with a strip-shaped positioning hole, and a positioning component is fixedly provided on the surface of the guide base, the positioning component is used to limit and fix the guide rod;

[0008] The positioning component includes a fixed frame fixedly connected to the surface of the guide base. The surface of the fixed frame has a circular through hole, and a positioning rod is slidably disposed on the inner wall of the circular through hole. The surface of the guide base has a positioning through hole, the position of which corresponds to the positioning rod, and the size of the positioning through hole matches the positioning rod.

[0009] In a preferred embodiment, one end of the positioning rod is fixedly connected to a pull ring, and a limit ring is fixedly connected to the surface of the positioning rod. A return spring is sleeved on the surface of the positioning rod, one end of the return spring is fixedly connected to the surface of the limit ring, and the other end of the return spring is fixedly connected to the surface of the fixed frame.

[0010] In a preferred embodiment, the upper surface of the guide base is provided with a threaded adjustment hole, and an adjustment screw is threadedly connected to the inner wall of the threaded adjustment hole. An adjustment shell is fixedly connected to the upper surface of the base plate, and a worm gear is rotatably arranged between the left and right inner walls of the adjustment shell. The top end of the adjustment screw is rotatably connected to the inner top wall of the adjustment shell, and a worm wheel is fixedly connected to the surface of the adjustment screw.

[0011] In a preferred embodiment, the worm wheel is positioned corresponding to the worm, and the worm meshes with the worm wheel. One end of the worm extends to the outside of the adjusting housing and is fixedly connected to an adjusting knob.

[0012] In a preferred embodiment, two corresponding limiting blocks are fixedly embedded on the surface of the base plate, and two strip-shaped keyways are opened on the back of the guide base. The positions of the strip-shaped keyways correspond to the limiting blocks, and the size of the strip-shaped keyways matches the limiting blocks.

[0015] As can be seen from the above, the unloading groove guide device provided by this utility model has the following technical effects.

[0016] Firstly, by setting an anti-reverse component on the surface of the guide base, when processing the workpiece in the unloading groove, the guide sleeve can be moved by the cylinder first, so that the guide rod passes through the workpiece pin hole. If the workpiece is not placed incorrectly, the guide rod will pass directly through the pin hole, the pressure plate will press the workpiece, the guide rod will retract, and processing will begin. If the center of the pin hole is not coaxial with the center of the workpiece or the workpiece is placed in reverse, causing the center of the pin hole to be not coaxial with the center of the guide rod, the guide rod will not pass through the workpiece pin hole, and the equipment will not proceed to the next step, thus achieving the purpose of error prevention. This reduces the scrapping of workpieces due to employee operation errors or workpieces being placed in reverse, and avoids abnormal situations such as tool breakage.

[0017] Secondly, by setting a guide base that can move up and down on the surface of the base plate, the guide base can be moved on the surface of the base plate by rotating the adjusting screw, which is used to adjust the height between the base plate and the guide base, so that the center of the workpiece is coaxial with the machine tool guide rod, thus making it convenient for the operator to adjust the height of the guide rod according to the different sizes of the workpiece; by setting a positioning component, the positioning rod can be inserted into the strip positioning hole on the surface of the guide sleeve by using a return spring, thereby limiting the guide sleeve and preventing the guide sleeve from rotating during operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figures 1-6 A load-bearing groove guide device includes a base plate 1, a guide base 2 slidably disposed on the front of the base plate 1, a through movable hole 3 opened on the side of the guide base 2, and an anti-reverse component 4 inserted and installed on the inner wall of the through movable hole 3. The anti-reverse component 4 is used to perform anti-reverse detection on the workpiece.

[0030] In a preferred embodiment, two corresponding limiting blocks 12 are fixedly embedded on the surface of the base plate 1, and two strip-shaped keyways 13 are opened on the back of the guide base 2. The position of the strip-shaped keyways 13 corresponds to the limiting blocks 12, and the size of the strip-shaped keyways 13 matches the limiting blocks 12. The guide base 2 is slidably connected to the surface of the limiting blocks 12 through the strip-shaped keyways 13.

[0031] The above technical solutions can be used to guide and limit the guide base 2 by using the keyway 13 and the limiting block 12, thereby improving the stability of the guide base 2 during its up-and-down movement.

[0032] It should be noted that the anti-reverse component 4 includes a guide sleeve 401, a guide rod 402 is inserted and installed at the left end of the guide sleeve 401, the right end of the guide rod 402 has a conical structure, and a rubber anti-slip sleeve 404 is fixedly provided on the surface of the guide rod 402.

[0033] It should be noted that the guide rod 402 is used to insert into the workpiece pin hole. The surface of the guide rod 402 is provided with a strip-shaped positioning hole 403. The surface of the guide base 2 is fixedly provided with a positioning component 5, which is used to limit and fix the guide rod 402.

[0034] The left and right ends of the guide base 2 are respectively fixed with a front cover 14 and a rear cover 15 by bolts. The guide sleeve 401 is slidably connected to the inner wall of the through movable hole 3, and the right end of the guide sleeve 401 is provided with a bolt fixing hole for connecting the cylinder.

[0035] It is worth noting that by setting an anti-reverse component 4 on the surface of the guide base 2, when processing the workpiece in the unloading groove, the guide rod 402 can pass through the workpiece pin hole. If the workpiece is not placed incorrectly, the guide rod 402 will pass directly through the pin hole, and processing can begin. If the center of the pin hole is not coaxial with the center of the workpiece or the workpiece is placed incorrectly, causing the center of the pin hole to be not coaxial with the center of the guide rod 402, the guide rod 402 will not pass through the workpiece pin hole, and the equipment will not proceed to the next step, thus achieving the purpose of preventing errors.

[0036] In a preferred embodiment, the upper surface of the guide base 2 is provided with a threaded adjustment hole 6, and the inner wall of the threaded adjustment hole 6 is threadedly connected to an adjustment screw 7. The upper surface of the base plate 1 is fixedly connected to an adjustment shell 8, and a worm gear 9 is rotatably arranged between the left and right inner walls of the adjustment shell 8. The top end of the adjustment screw 7 is rotatably connected to the inner top wall of the adjustment shell 8, and a worm wheel 10 is fixedly connected to the surface of the adjustment screw 7. The position of the worm wheel 10 corresponds to that of the worm gear 9, and the worm gear 9 meshes with the worm wheel 10. One end of the worm gear 9 extends to the outside of the adjustment shell 8 and is fixedly connected to an adjustment knob 11.

[0037] It is worth noting that by setting a guide base 2 that can move up and down on the surface of the base plate 1, the worm 9 can be rotated by rotating the adjustment knob 11. The worm 9 drives the worm wheel 10 to rotate, which in turn drives the adjustment screw 7 to rotate. The adjustment screw 7 drives the guide base 2 to move on the surface of the base plate 1 through the threaded adjustment hole 6, which is used to adjust the height between the base plate 1 and the guide base 2, so that the center of the workpiece is coaxial with the machine tool guide rod 402, thus making it convenient for the operator to adjust the height of the guide rod 402 according to the different sizes of the workpiece.

[0038] It should be noted that the positioning component 5 includes a fixing frame 502 fixedly connected to the surface of the guide base 2. The surface of the fixing frame 502 has a circular through hole, and a positioning rod 503 is slidably disposed on the inner wall of the circular through hole. The surface of the guide base 2 has a positioning through hole 504, the position of which corresponds to the positioning rod 503, and the size of the positioning through hole 504 matches that of the positioning rod 503.

[0039] In a preferred embodiment, a pull ring 505 is fixedly connected to one end of the positioning rod 503, and a limit ring 506 is fixedly connected to the surface of the positioning rod 503. A reset spring 501 is sleeved on the surface of the positioning rod 503. One end of the reset spring 501 is fixedly connected to the surface of the limit ring 506, and the other end of the reset spring 501 is fixedly connected to the surface of the fixing frame 502.

[0040] It is worth noting that by setting the positioning component 5 on the surface of the guide base 2, when positioning the guide sleeve 401, the return spring 501 can drive the positioning rod 503 to be inserted into the strip positioning hole 403 on the surface of the guide sleeve 401, thereby limiting the guide sleeve 401 and preventing the guide sleeve 401 from rotating during operation.

[0041] Working principle: When processing the unloading groove workpiece, firstly, the guide base 2 is installed on the base plate 1. Then, the rear end cover 15 is fixedly connected to the tail of the guide base 2 with bolts. Next, the guide sleeve 401 is placed into the through movable hole 3 of the guide base 2. Then, the guide rod 402 is inserted into the guide sleeve 401 and locked. Finally, the front end cover 14 is locked on the left side of the guide base 2. The tail of the guide sleeve 401 has an M10 threaded hole for connecting a cylinder. Then, the operator places the workpiece on the surface of the processing table. The cylinder is used to push the guide sleeve 401 to move in the through movable hole 3 of the guide base 2, thereby driving the guide rod 402 to pass through the workpiece pin. If the workpiece is placed correctly, the guide rod 402 will pass directly through the pin hole, and then the pressure plate will press the workpiece. The guide rod 402 will then retract, and the unloading groove machining will begin. If the center of the pin hole is not coaxial with the center of the workpiece, or if the workpiece is placed in the wrong position, causing the center of the pin hole to be not coaxial with the center of the guide rod 402, the guide rod 402 will not be able to pass through the workpiece pin hole, and the equipment will not proceed to the next step. This achieves the purpose of error prevention, reduces the scrapping of workpieces due to employee operation errors or workpiece placement in the wrong position, and avoids abnormal situations such as tool breakage. After adopting this method, the quality of the unloading groove is greatly improved, and the quality abnormalities such as the unloading groove angle being crooked and the workpiece direction being reversed in the early stage are solved.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
