Description

Technical Field

[0001] The present invention relates to the technical field of milling machines, and particularly to a metal part processing tooling with an angle adjustment effect. Background Art

[0002] When milling a metal part using a milling machine, the workpiece needs to be fixed on the workbench of the milling machine. The workbench can be adjusted in three directions: the X-axis, the Y-axis, and the Z-axis. During the milling process of the milling machine, a large amount of chips will be generated. These chips fall on the guide rails of the milling machine, which will cause vibration or jamming when the workbench moves along the guide rails, affecting the machining accuracy and also the service life of the guide rails. Setting up a processing tooling on the guide rails is an important measure to block chips and protect the guide rails.

[0003] Since there is a spatial intersection between the Y-axis guide rail and the Z-axis guide rail of some milling machines, it is difficult to effectively protect them using conventional processing toolings. Because ordinary processing toolings are mainly telescopic structures designed for linear motion, there are the following defects for this multi-directional motion: Rigid processing toolings will cause mechanical interference in the intersection area, while flexible processing toolings will have problems such as extrusion stacking, twisting and bulging, or sagging, and cannot achieve reliable protection following the moving parts.

[0004] Taking the flexible bellows processing tooling as an example, its typical failure scenarios during the operation of the milling machine are as follows: When the workbench moves to the rightmost end of the Y-axis and the uppermost end of the Z-axis, the processing tooling synchronously contracts to the smallest size in the Y and Z directions, and the contracted part accumulates in the guide rail intersection area, forming extrusion stacking and twisting and bulging (as Figure 4 shown), which not only hinders the sliding of the workbench but may even cause the processing tooling to fold and fall off; When the workbench moves to the leftmost end of the Y-axis and the lowermost end of the Z-axis, the processing tooling synchronously stretches to the largest size in the biaxial direction. At this time, the processing tooling is straightened and suspended, unable to fit the complex contour of the guide rail, forming a protection gap and allowing foreign objects to invade (as Figure 3 shown).

[0005] Currently, the protection measure adopted by the milling machine is to use a flexible bellows processing tooling for the Y-axis guide rail in front of the workbench, while at the intersection of the Y-axis guide rail and the Z-axis guide rail behind the workbench, a chip guard rubber is installed for protection. The chip guard rubber also has the above-mentioned stacking and bulging problems (as Figure 3 , Figure 4 shown), and both ends of the chip guard rubber are fixed, with both sides in an open state, unable to form a closed protection for the guide rail.

[0006] Therefore, aiming at the structural characteristics of the multi-angle adjustment of the milling machine workbench, it is urgent to design a new type of tooling that can efficiently protect the intersection area of the Y-axis and Z-axis guide rails and can move synchronously following the multi-angle adjustment of the workbench to solve the interference, stacking, and chip leakage problems of the existing processing toolings during multi-axis linkage. Summary of the Invention

[0022] The inner wheel of the horizontal pulley is rollingly installed in the horizontal chute, and the inner wheel of the vertical pulley is rollingly installed in the vertical chute.

[0030] 2: It provides closed protection for the Y-axis guide rail and the Z-axis guide rail. No matter how the workbench moves in the Y-axis and Z-axis directions, it can effectively follow the movement of the workbench for telescopic adjustment while maintaining a closed state throughout the process.

[0031] 3: It has a self-cleaning effect. When the milling machine is working, a large amount of chips will fall on the front-end processing tooling and the rear-end processing tooling. The tops of the front-end processing tooling and the rear-end processing tooling of this application adopt an inclined diversion design and a flexible cover. During the telescopic adjustment process, the tremors generated by the telescopic adjustment of the cover will automatically shake off the chips and coolant on the top, eliminating the need for manual cleaning.

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] Refer to Figures 1 - 14 , a metal part processing tooling with multi-angle adjustment effect, including a milling machine 100, a lifting table 200, a front-end processing tooling 300, a rear-end processing tooling 400 and a collection tank 500. The milling machine 100 is perpendicular to the ground, and the milling machine 100 is fixedly installed with a Z-axis guide rail 110 along its own direction. The lifting table 200 is slidably installed on the Z-axis guide rail 110, and the lifting table 200 can move up and down as a whole along the Z-axis guide rail 110.

[0049] The upper end surface of the lifting table 200 is fixedly installed with a Y-axis guide rail 210. The saddle 220 is slidably installed on the Y-axis guide rail 210. The saddle 220 can move as a whole along the Y-axis guide rail 210. The workbench 230 is slidably installed on the saddle 220, and the workbench 230 can move along the X-axis direction on the saddle 220 (it should be noted that the workbench 230 is moved and adjusted by a bottom lead screw in the X-axis direction, so there is no need to set up processing tooling in the X-axis direction).

[0050] Since the end of the Y-axis guide rail 210 is perpendicular to the Z-axis guide rail 110, if a conventional flexible processing tooling is used, during the movement of the workbench 230, problems such as extrusion stacking, twisting bulge, and collapse will occur at the junction (such as Figure 3 and Figure 4As shown in the figure, it should be noted that by using a rigid processing tooling, the shape and protection range of the processing tooling can be always maintained, avoiding such problems. However, some milling machines are not suitable for using rigid processing tooling, and there are two reasons for this. First, when the processing tooling shrinks to the minimum amount simultaneously in the directions of the Y-axis guide rail and the Z-axis guide rail, there is a risk of interference at the junction. Second, the adjustable range of this type of milling machine is relatively narrow. When using a rigid processing tooling for protection, it will further lead to a reduction in the adjustable range, which to a certain extent limits the movement space of some components of the milling machine, making the originally limited adjustable range even smaller.

[0051] For the above reasons, this type of milling machine is more suitable for using a flexible processing tooling. However, when using a flexible processing tooling, problems such as extrusion stacking, twisting and bulging, and collapse mentioned above will occur. Combining with the usage situation of existing milling machines, we found that if the processing tooling can always maintain the initial design state at the junction of the Y-axis guide rail and the Z-axis guide rail of the milling machine (such as Figure 6 the state shown at b in the figure), then the problems such as extrusion stacking, twisting and bulging, and collapse of the processing tooling can be solved. Next, the structure of the rear-end processing tooling 400 will be used to illustrate how the present application achieves the above purpose.

[0052] The rear-end processing tooling 400 includes a rear-end flexible cover body 410, a main rear-end skeleton 420, a secondary rear-end skeleton 430, a main rear-end connecting plate 440, a secondary rear-end connecting plate 450, a traction rope 460, and a rope tightener 470. The left end of the rear-end flexible cover body 410 is fixed to the main rear-end connecting plate 440, and the right end is fixed to the secondary rear-end connecting plate 450. The main rear-end connecting plate 440 is fixedly installed on the saddle 220, and the secondary rear-end connecting plate 450 is fixedly installed on the top end surface of the Z-axis guide rail 110;

[0053] As can be seen from the above, the rear-end processing tooling 400 is overall in an L shape, covering half of the Y-axis guide rail 210 and half of the Z-axis guide rail 110. The part covering the Y-axis guide rail 210 is supported by the main rear-end skeleton 420. There are multiple main rear-end skeletons 420, which are evenly distributed along the Y-axis guide rail 210. The area of the rear-end processing tooling 400 from the main rear-end connecting plate 440 to the rightmost main rear-end skeleton 420 (that is, the part covering the Y-axis guide rail 210) is the horizontal telescopic part a, and the area of the rear-end processing tooling 400 from the secondary rear-end skeleton 430 to the secondary rear-end connecting plate 450 (that is, the part covering the Z-axis guide rail 110) is the vertical telescopic part c.

[0054] When the saddle 220 moves along the Y-axis guide rail 210, since the end of the lateral telescopic part a is fixed to the saddle 220, the lateral telescopic part a will expand and contract accordingly. During this process, since the bottom of the main rear-end framework 420 is slidably mounted in the lateral chute 421, the main rear-end framework 420 that supports the lateral telescopic part a will also slide accordingly. That is to say, when the workbench 230 moves along the Y-axis guide rail 210, the lateral telescopic part a of the rear-end processing tooling 400 will expand and contract accordingly.

[0055] When the workbench 230 moves along the Z-axis guide rail 110, that is, when the lifting platform 200 as a whole moves up and down along the Z-axis guide rail 110, at this time, the lateral telescopic part a will move up and down together, but will not change its telescopic state, while the vertical telescopic part c will change its telescopic state. This process is mainly achieved through the towing rope 460 and the rope tightener 470. Since the towing rope 460 is wound by the rope tightener 470 and is always in a taut state (the principle of the rope tightener 470 is similar to that of a tape measure), therefore, when the lifting platform 200 as a whole moves up and down along the Z-axis guide rail 110, the towing rope 460 will pull the secondary rear-end framework 430 up and down. Since the secondary rear-end framework 430 is slidably mounted on the vertical chute 431, and the vertical chute 431 is fixedly mounted on the milling machine 100 along the direction of the Z-axis guide rail 110, the secondary rear-end framework 430 will move up and down along the vertical chute 431, and at the same time, the rear-end flexible cover 410 located above the secondary rear-end framework 430 will expand and contract accordingly.

[0056] The area between the rightmost main rear-end framework 420 and the secondary rear-end framework 430 of the rear-end processing tooling 400 is the junction part b. The junction part b is supported by the rightmost main rear-end framework 420 and the secondary rear-end framework 430. Therefore, the state of the junction part b is determined by the position states of the rightmost main rear-end framework 420 and the secondary rear-end framework 430.

[0057] The saddle 220 is located on the left side of the rear-end processing tooling 400. Therefore, when the saddle 220 moves along the Y-axis guide rail 210, the main rear-end framework 420 on the left side moves accordingly first, while the displacement of the rightmost main rear-end framework 420 is very small; since the secondary rear-end framework 430 is fixed to the towing rope 460 (it can be fixed by bonding, binding, etc.), the secondary rear-end framework 430 is pulled up and down by the towing rope 460. It should be noted that only when the lifting platform 200 as a whole moves up and down along the Z-axis guide rail 110, the towing rope 460 will pull the rear-end framework 430 up and down, and when the lifting platform 200 moves up and down as a whole, it also means that the main rear-end framework 420 also moves up accordingly. Therefore, the relative positions of the rightmost main rear-end framework 420 and the secondary rear-end framework 430 are almost unchanged.

[0058] In addition, a traction rope 460 located at the joint b is sleeved with a spring 461. Two ends of the spring 461 respectively abut against the rightmost main rear-end skeleton 420 and the secondary rear-end skeleton 430. The spring 461 also plays a role in shaping the joint b.

[0059] As can be seen from the above, regardless of how the workbench 230 moves along the Y-axis guide rail 210 and the Z-axis guide rail 110, the rear-end processing tooling 400 accurately controls the telescopic amount in the horizontal telescopic part a and the vertical telescopic part c. The joint b between the main rear-end skeleton 420 and the secondary rear-end skeleton 430 always remains in the initial state.

[0060] Combined with Figure 10 and Figure 11 it can be known that the rope tightener 470 includes a first housing 471, a second housing 472, a central shaft 473, a coil spring 474 and a guide wheel 475. The first housing 471 and the second housing 472 are columnar housings and are fixedly connected to each other. The central shaft 473 is fixedly installed at the central position of the first housing 471. The guide wheel 475 is installed inside the first housing 471 and the second housing 472. The guide wheel 475 is sleeved outside the central shaft 473 and can rotate around the central shaft 473. The coil spring 474 is located inside the guide wheel 475. One end of the coil spring 474 is fixed to the central shaft 473, and the other end passes through the guide wheel 475 and is fixedly connected to the traction rope 460. The traction rope 460 is wound around the guide wheel 475. Notches 4711 are formed on the first housing 471 and the second housing 472. The traction rope 460 passes through the notches 4711 and exits the rope tightener 470. The end of the traction rope 460 is fixedly installed on the main rear-end connecting plate 440.

[0061] The structure of the rope tightener 470 is similar to that of a tape measure, which plays a role in winding up the traction rope 460 to keep the traction rope 460 always in a taut state. Therefore, when the workbench 230 moves upward along the Z-axis guide rail 110, the rope tightener 470 will automatically wind up a certain length of the traction rope 460. When the workbench 230 moves downward along the Z-axis guide rail 110, the rope tightener 470 will automatically release a certain length of the traction rope 460. When the traction rope 460 is wound up or released by a certain length, the effect is that it will pull the secondary rear-end skeleton 430 to move up and down.

[0062] Two traction ropes 460 and two rope tighteners 470 are provided and are installed on both sides of the rear-end processing tooling 400 with the central axis of the Y-axis guide rail 210 as the symmetry center. The two rope tighteners 470 are fixedly installed on the secondary rear-end connecting plate 450. The two traction ropes 460 are arranged on both sides of the rear-end flexible cover 410. The rope tightener 470 controls the telescopic movement of the vertical telescopic part c of the rear-end flexible cover 410 by pulling and relaxing the traction rope 460.

[0063] Combined with Figures 1 to 14It can be seen that the front-end processing tooling 300 is composed of a front-end flexible cover 310, a front-end skeleton 320, a main front-end connecting plate 330, and a secondary front-end connecting plate 340. The left end of the front-end flexible cover 310 is fixed to the secondary front-end connecting plate 340, and the right end is fixed to the main front-end connecting plate 330. The main front-end connecting plate 330 is fixedly installed on the saddle 220, and the secondary front-end connecting plate 340 is fixedly installed on the left end face of the Y-axis guide rail 210.

[0064] The front-end processing tooling 300 is used to protect the Y-axis guide rail 210 located in front of the workbench 230. A plurality of front-end skeletons 320 are provided and are evenly distributed along the Y-axis guide rail. These front-end skeletons 320 are all fixedly connected to the front-end flexible cover 310, and at the same time, the bottom of the front-end skeleton 320 is slidably installed on the transverse chute 421.

[0065] There are the following differences between the front-end skeleton 320, the main rear-end skeleton 420, and the secondary rear-end skeleton 430: A plurality of front-end skeletons 320 are provided, and no limit rings 423 are provided on both sides of the front-end skeleton 320; a plurality of main rear-end skeletons 420 are provided, and limit rings 423 are fixedly installed at both positions of the main rear-end skeleton 420, and the towing rope 460 passes through the limit rings 423; one secondary rear-end skeleton 430 is provided, no limit rings 423 are provided on both sides of the secondary rear-end skeleton 430, and the secondary rear-end skeleton 430 is fixedly connected to the towing rope 460.

[0066] Combined with Figures 1 to 14 It can be seen that a plurality of transverse pulleys 422 are slidably installed in the transverse chute 421, and a plurality of vertical pulleys 432 are slidably installed in the vertical chute 431; both the transverse pulley 422 and the vertical pulley 432 are composed of an outer wheel 4221 and an inner wheel 4222. The outer wheel 4221 and the inner wheel 4222 are connected by a shaft, and the inner wheel 4222 can rotate while the outer wheel 4221 is fixed. The outer wheel 4221 of the transverse pulley 422 is fixedly connected to the front-end skeleton 320 and the main rear-end skeleton 420 installed on the Y-axis guide rail, and the outer wheel 4221 of the vertical pulley 432 is fixedly connected to the secondary rear-end skeleton 430; the inner wheel 4222 of the transverse pulley 422 is rotatably installed in the transverse chute 421, and the inner wheel 4222 of the vertical pulley 432 is rotatably installed in the vertical chute 431.

[0067] The edges of the front-end flexible cover 310 and the rear-end flexible cover 410 cover the transverse chute 421 and the vertical chute 431. The outer wheels 4221 of the transverse pulley 422 and the vertical pulley 432 are both located outside the front-end flexible cover 310 and the rear-end flexible cover 410, and the inner wheels of the transverse pulley 422 and the vertical pulley 432 are both located inside the front-end flexible cover 310 and the rear-end flexible cover 410.

[0068] The structural design of the outer wheel 4221 and the inner wheel 4222 of the above-mentioned transverse pulley 422 and vertical pulley 432 is to allow the front end flexible cover body 310 and the rear end flexible cover body 410 to have a better sealing effect, so that the front end flexible cover body 310 and the rear end flexible cover body 410 always keep in contact with the transverse slide groove 421 and the vertical slide groove 431, effectively preventing the intrusion of impurities such as cutting debris and dust.

[0069] In addition, the main front end connecting plate 330 and the main rear end connecting plate 440 are door-shaped, matching the contour of the Y-axis guide rail 210, and the secondary front end connecting plate 340 and the secondary rear end connecting plate 450 are quadrilaterals, fixedly shielded on the end faces of the Y-axis guide rail 210 and the Z-axis guide rail 110. With this design, the front end processing tooling 300 and the rear end processing tooling 400 will form a closed protection with the Y-axis guide rail 210 and the Z-axis guide rail 110 during installation.

[0070] Combination Figures 1 to 14 It can be seen that the transverse slide groove 421 is fixedly installed in the collecting groove 500, and the collecting groove 500 is arranged along the Y-axis guide rail 210. The collecting groove 500 is fixedly installed on the side wall of the lifting platform 200. Since the front-end processing tooling 300 and the rear-end processing tooling 400 are tilted toward the collecting groove 500 as a whole, during the extension and retraction process of the front-end processing tooling 300 and the rear-end processing tooling 400, the front-end flexible cover body 310 and the rear-end flexible cover body 410 will shake slightly (shaking caused by their own extension and retraction deformation). In addition, the inclined design of the top can allow the front-end flexible cover body 310 and the rear-end flexible cover body 410 to guide the chips and coolant splashed on the top of themselves into the collecting groove 500 during the extension and retraction process. The front-end flexible cover body 310 and the rear-end flexible cover body 410 are made of elastic wear-resistant materials with a smooth surface to facilitate the sliding of chips.

[0071] A funnel-shaped waste chip trough 510 is arranged at the bottom of the collecting trough 500. The waste chip trough 510 and the collecting trough 500 are an integrated structure. The bottom surface of the collecting trough 500 is inclined toward the waste chip trough 510. Since the bottom surface of the collecting trough 500 is inclined, the chips and coolant entering the collecting trough 500 will automatically flow along the bottom surface to the waste chip trough 510. A filter net 511 is fixedly installed in the waste chip trough 510. The filter net 511 filters the chips and the coolant. After filtering, the chips will be retained in the waste chip trough 510 by the filter net 511, and the coolant will flow into the liquid collecting bottle 520 below, thereby realizing automatic separation of the chips and the coolant.

[0072] The chips will eventually accumulate in the waste chip trough 510, and the coolant will enter the liquid collecting bottle 520. People only need to regularly clean the chips in the waste chip trough 510 and pour out the coolant in the liquid collecting bottle 520, thereby reducing the workload required for cleaning.

[0073] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
