Abstract
Description
Technical Field
[0001] The utility model relates to the field of processing tooling, in particular to a fixing tooling for bed body processing. Background Technique
[0002] A casting bed body refers to the basic structure inside a CNC gantry milling machine or a CNC gantry machining center for placing important components and equipment. It is usually made of cast iron material and is the basic supporting part of the entire machine.
[0003] When milling and planing a large casting bed body, due to the complex structure of the bed body and the fact that large casting bed bodies are all single-piece and small-batch, the fixed fixture cannot adapt to the complex structure of the casting bed body. In the prior art, a large casting bed body is fixed by cooperating a pressing plate tooling with the workbench chute of the processing machine tool. The pressing plate tooling includes a pressing plate, a cushion block, and a pressing bolt. The lower part of the pressing bolt is arranged in the workbench chute, and the pressing plate is tightened downward. After the pressing plate is stressed, one end is tightly pressed on the bed body and the other end is tightly pressed on the cushion block.
[0004] Adopting the above technical solution, the height of the cushion block remains unchanged. Since the sizes and structures of different bed bodies are different, it cannot be guaranteed that the fixing tooling can be universal. To meet the fixing requirements of various bed bodies, when a smaller-sized bed body needs to be fixed, multiple pressing plates or gaskets are often stacked to adjust the height of the uppermost pressing plate. This fixing method cannot guarantee reliability and is prone to misalignment of multiple pressing plates or gaskets during the processing. In the light case, it affects the machining accuracy of the bed body, and in the serious case, it causes the bed body to fall and results in safety accidents. Content of the Utility Model
[0005] In order to solve the technical problem in the above-mentioned prior art that the fixing tooling has insufficient universality when the bed body is processed on a planer and cannot reliably fix bed bodies of various structures and sizes, the utility model provides a fixing tooling for bed body processing, which can meet the fixing use of bed bodies of various sizes and has a relatively high degree of generalization.
[0006] The technical solution adopted by the utility model to solve the above technical problem is: a fixing tooling for bed body processing, including a pressing plate, one end of the pressing plate can be tightly pressed on the bed body, and further includes: a cushion block, one end of the cushion block is provided with a supporting part, the supporting part is provided with a plurality of steps, and the other end of the pressing plate can be tightly pressed on the steps; a tension rod, the tension rod includes a threaded part at the upper part, the threaded part passes through the pressing plate and is provided with a locking nut, the lower part of the tension rod is provided with a limiting block, and the limiting block can move along the chute of the machine tool workbench. When the tension rod is tightened, the limiting block can abut against the chute.
[0007] The utility model can adjust the height of the pressing plate by arranging a plurality of steps on the cushion block to match bed bodies of different sizes, and has a relatively high level of generalization.
[0008] Further, a boss is provided on one side of the end of the pressing plate. The upper surface and the lower surface of the boss can both be tightly pressed on the step, and the lower surface of the boss is coplanar with the lower surface of the pressing plate.
[0009] By providing the boss, the present utility model can further adjust the height of the contact surface between the pressing plate and the bed body, further divide the dimension adjustment range on the basis of the step height, and further improve the generalization level.
[0010] Further, bosses are provided at both ends of the pressing plate, and the heights of the two bosses are different.
[0011] By providing bosses with two heights, the present utility model enables the dimension adjustment range to have two splitting methods, greatly improving the generalization level.
[0012] Further, the height of one of the bosses is one-third of the thickness of the pressing plate, and the height of the other boss is two-thirds of the thickness of the pressing plate. The thickness of the pressing plate is the same as the thickness of the step.
[0013] Further, the height of the step is 15 mm to 25 mm.
[0014] Further, a spirit level is provided on the pressing plate.
[0015] The present utility model ensures that the pressing plate is in a horizontal state after adjustment through the spirit level.
[0016] Further, a weight-reducing hole is provided on the cushion block.
[0017] Further, an anti-slip nut is also provided on the thread, and the anti-slip nut is arranged in an opposing manner above the locking nut.
[0018] Further, the limiting block has a convex-shaped structure.
[0019] Further, a thread is provided at the lower part of the tension rod, and the limiting block is threadedly connected to the tension rod.
[0020] By using a threaded connection to connect the limiting block, the present utility model can adjust the position of the limiting block, enabling the tension rod to match pressing plates of different heights.
[0021] From the above technical solutions, it can be seen that the present utility model has the following advantages:
[0022] The utility model provides a fixing tooling for bed body processing. By arranging a plurality of steps on the cushion block, the height of the pressing plate can be adjusted to match bed bodies of different sizes, eliminating the need to stack multiple pressing plates or gaskets, with a relatively high level of generalization and safety. By arranging a boss, the height of the contact surface between the pressing plate and the bed body can be further adjusted, further dividing the range of size adjustment on the basis of the step height, and further improving the level of generalization.

[0028] In order to make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.
[0029] As Figures 1 to 3As shown in the figure, this specific embodiment provides a fixing tooling for bed machining, including a pressing plate 5, a cushion block 11 and a tension rod 6. One end of the pressing plate 5 can be tightly pressed on the bed 4. One end of the cushion block 11 is provided with a supporting part, and the supporting part is provided with a plurality of steps. The other end of the pressing plate 5 can be tightly pressed on the steps. The cushion block 11 can be tightly pressed on the workbench 3 of the processing machine tool 1 under the action of the pressing plate 5. The tension rod 6 includes a threaded part at the upper part. A hole is provided at the corresponding position of the pressing plate 5. After the threaded part penetrates through the pressing plate 5, a locking nut 7 is provided. A limiting block 9 is provided at the lower part of the tension rod 5. The limiting block 9 can move along the sliding groove 2 of the machine tool workbench 3. When the tension rod 6 is tightened, the limiting block 9 can abut against the sliding groove 2.
[0030] In this specific embodiment, by providing a plurality of steps on the cushion block 11, the height of the pressing plate 5 can be flexibly adjusted according to the height of the bed 4, which can match bed bodies 4 of different sizes. There is no need to adjust the height by stacking gaskets or using multiple pressing plates 5, and the generalization level is relatively high, and the fastening is firm and safe.
[0031] As Figure 1 and Figure 3 shown, since the height of the pressing plate 5 increases by the height of one step each time a different step is used for support, the height of the step is the adjustment range. However, sometimes, the problem of excessive adjustment may occur. To avoid this technical problem, in this specific embodiment, a convex platform is provided on one side of the end of the pressing plate 5. The upper surface and the lower surface of the convex platform can both be tightly pressed on the steps. The lower surface of the convex platform is coplanar with the lower surface of the pressing plate 5. When in use, the pressing plate 5 can be used in the forward or reverse direction according to the height situation. By providing the convex platform, the height of the contact surface between the pressing plate 5 and the bed 4 can be further adjusted, and the adjustment range of the size is further divided on the basis of the step height, further improving the generalization level. Preferably, convex platforms are provided at both ends of the pressing plate 5, and the heights of the two convex platforms are different. By providing two convex platforms with different heights, there are two ways to divide the adjustment range of the size, greatly improving the generalization level. In this specific embodiment, the height of one convex platform is one-third of the thickness of the pressing plate 5, and the height of the other convex platform is two-thirds of the thickness of the pressing plate 5. The thickness of the pressing plate 5 is the same as the thickness of the step. The height of the step is 15 mm to 25 mm. In this specific embodiment, the step height is 21 mm.
[0032] As Figure 1 and Figure 3 shown, in order to ensure that the pressing plate 5 is adjusted to a horizontal state and provide sufficient friction for surface contact with both the cushion block 11 and the machine tool, a spirit level 10 is provided on the pressing plate 5 in this specific embodiment.
[0033] As Figure 1 and Figure 3 shown, in order to achieve lightweight design, a weight-reducing hole is provided on the cushion block 11 in this specific embodiment.
[0034] As Figure 1 and Figure 3 shown, in order to ensure that the lock nut 7 of the tension rod 6 becomes loose, in this specific embodiment, an anti-slip nut 8 is further provided on the thread, and the anti-slip nut 8 is arranged in an opposing manner above the lock nut 7.
[0035] As Figure 1 and Figure 3 shown, in this specific embodiment, the limiting block 9 has a convex structure and matches the cross-sectional shape of the sliding groove 2 of the machine tool workbench 3. When the tension rod 6 is tightened, the upper surface of the limiting block 9 abuts against the sliding groove 2 to achieve limiting; since the height of the pressing plate 5 can be adjusted, in order to ensure that the pressing plate 5 is at the highest position and there is still room for installing the lock nut 7 and the anti-slip nut 8 on the tension rod 6, in this specific embodiment, a thread is provided at the lower part of the tension rod 6, and the limiting block 9 is threadedly connected to the tension rod 6.
[0036] It can be seen from the above specific embodiments that the present utility model has the following beneficial effects:
[0037] 1. By providing a plurality of steps on the spacer block 11, the height of the pressing plate 5 can be adjusted to match bed bodies 4 of different sizes, eliminating the need to stack multiple pressing plates 5 or gaskets, resulting in a relatively high level of generalization and safety;
[0038] 2. By providing a convex platform, the height of the contact surface between the pressing plate 5 and the bed body 4 can be further adjusted, further dividing the range of size adjustment on the basis of the step height, and further improving the level of generalization;
[0039] 3. By providing convex platforms of two heights, there are two ways to divide the range of size adjustment, greatly improving the level of generalization;
[0040] 4. By using a threaded connection for the limiting block 9, the position of the limiting block 9 can be adjusted, enabling the tension rod 6 to match pressing plates 5 of different heights.
[0041] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
