Description

Technical Field

[0001] The utility model relates to the technical field of bearing cover processing, in particular to a device for enhancing the processing efficiency of bearing covers. Background Technique

[0002] As Figure 1 The finished bearing cover shown in it has a thickness of 8 mm, an outer diameter of 180 mm, a hole diameter of 129 mm, a step diameter of 140 mm, a step depth of 3 - 0.1 mm. Drilling is required at the step, and the outer shape needs to be milled; the bearing cover blank is only processed with the outer diameter, so only the outer diameter is not processed in the subsequent processes, and the rest need to be processed.

[0003] In the early stage, the step was generally processed by a lathe and then drilled with an ordinary drill press, and then the profile was milled with a milling machine. The processing cycle was long and a large number of personnel were required. Later, with the development of technology, technical personnel directly processed through a vertical milling machine or a vertical machining center after setting up a special fixture for the bearing end cover. For example, a bearing end cover processing die disclosed in the prior art; includes a bottom plate and a clamping device. The bottom plate has mounting holes. The clamping device includes a T-shaped plate, a hydraulic cylinder, a rack, a clamping block and an auxiliary component. The T-shaped plate is fixedly connected to the bottom plate. The hydraulic cylinder is fixedly connected to the T-shaped plate. The rack is fixedly connected to the output end of the hydraulic cylinder. The clamping block is fixedly connected to the rack. The auxiliary component is arranged on one side of the bottom plate. When in use, the hydraulic cylinder pushes out the rack, and the rack drives the clamping block to abut against the workpiece. At the same time, the auxiliary component performs clamping assistance, and the outer cylindrical side surface of the workpiece can be divided into three clamping points that are 120° to each other, so as to center and clamp the workpiece, and further realize that when processing the bearing end cover, the self-centering degree during workpiece positioning can be improved, and the machining accuracy of part dimensions can be improved;

[0004] However, the above disclosed technology can only clamp bearing covers with a longer journal or a larger thickness. When facing a bearing cover with a smaller thickness, it is difficult to ensure flatness during clamping, and the thickness of its clamping block significantly exceeds that of the bearing cover, resulting in the inability to process the step on the bearing cover. Therefore, it is necessary to improve and optimize the structure of the processing device for thin bearing covers to reduce the number of clamping times, improve clamping stability, and increase production efficiency.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1 to 4, an efficiency-enhancing device for bearing cover processing provided by the utility model: includes a machine tool table, a strong suction cup 1, a positioning plate 2, a squeezing pressing plate 3, a pressing pressing plate 4, a baffle 5, and a bearing cover finished product 7. There is a step 701 at the intersection of the upper wall and the circumferential outer wall of the bearing cover finished product 7, and the bearing cover finished product 7 is arranged on the upper wall of the strong suction cup 1;

[0027] As Figure 4 shown, in this embodiment, the bearing cover finished product 7 is processed from a bearing cover blank 6. It is necessary to process a step 701, a milling machine profile, and drill holes on the bearing cover blank 6. During processing and clamping, the bearing cover blank 6 is clamped. After processing, it is the bearing cover finished product 7. Actually, it is the same product. The bearing cover finished product 7 and the bearing cover blank 6 are names in different processing states. For the convenience of description in the following of this embodiment, all are described by taking the bearing cover as the name;

[0028] As Figure 1 and Figure 2 shown, in order to adsorb and fix the lower wall of the bearing cover finished product 7, the strong suction cup 1 is fixedly connected to the upper wall of the machine tool table. After the strong suction cup 1 is turned on, it can form a downward adsorption fixing force on the bearing cover through strong magnetism, avoiding the clamping failure caused by the upward movement of the bearing cover during processing;

[0029] As Figure 1 (should be Figure 1 instead of Figure 1 and Figure 2 in the original, assumed to be a typo) and Figure 2 shown, in order to position the left side of the bearing cover, the baffle 5 is fixedly connected to the left wall of the strong suction cup 1. The upper end of the baffle 5 protrudes from the upper wall of the strong suction cup 1 and there is a notch 501 at the upper end of the baffle 5. The lower wall inside the notch 501 is flush with the upper wall of the strong suction cup 1. The front wall and the rear wall inside the notch 501 are both arc-shaped and the radius of the arc is the same as the radius of the circumferential outer wall of the bearing cover finished product 7. The drop between the upper end of the baffle 5 and the upper wall of the strong suction cup 1 is less than the thickness of the step 701. The left wall of the bearing cover finished product 7 abuts against the inner wall of the notch 501, forming a positioning effect on the left wall of the bearing cover through the notch 501. The height of the baffle 5 protruding from the strong suction cup 1 is less than the thickness of the step 701 to prevent the baffle 5 from interfering with the processing tool when processing the step 701;

[0030] As Figure 1 , Figure 2As shown in the figure, in order to position the rear side of the bearing cover, the positioning plate 2 is fixedly connected to the upper wall of the powerful suction cup 1. The positioning plate 2 is fixedly connected to the upper wall of the powerful suction cup 1 through the pressing plate 4. The rear wall of the finished bearing cover 7 abuts against the positioning plate 2. On the side of the positioning plate 2 facing the finished bearing cover 7, there is a first arc groove 201. The radius of the first arc groove 201 is the same as the radius of the circumferential outer wall of the finished bearing cover 7. The rear wall of the finished bearing cover 7 abuts against the inner side wall of the first arc groove 201. The thickness of the positioning plate 2 is less than the thickness of the step 701. After the bearing cover abuts against the notch 501, the positioning plate 2 is placed on the rear side of the bearing cover and the first arc groove 201 is tightened against the rear wall of the bearing cover. Then, the positioning plate 2 is fixed by the pressing plate 4. The rear positioning of the bearing cover is formed by the first arc groove 201 of the positioning plate 2. The thickness of the positioning plate 2 being less than the thickness of the step 701 is to prevent the positioning plate 2 from interfering with the machining tool during the machining of the step 701;

[0031] As Figure 1 , Figure 2 and Figure 3 shown in the figure, in order to clamp the bearing cover, the finished bearing cover 7 is tightened between the positioning plate 2 and the notch 501 through the squeezing plate 3. The squeezing plate 3 is arranged on the right front side of the finished bearing cover 7. One end of the squeezing plate 3 facing the finished bearing cover 7 is provided with a squeezing head 302. The squeezing plate 3 and the pressing plate 4 are respectively detachably connected to the machine tool table through a set of screws. One end of the squeezing head 302 away from the squeezing plate 3 is provided with a second arc groove 303. The radius of the second arc groove 303 is the same as the radius of the circumferential outer wall of the finished bearing cover 7. The front wall of the finished bearing cover 7 abuts against the inner side wall of the second arc groove 303. The inner wall of the squeezing plate 3 is provided with an oblong groove 301 that runs through up and down. The length direction of the oblong groove 301 is parallel to the length direction of the squeezing plate 3, and the extension line of the center line between the left inner wall and the right inner wall of the oblong groove 301 intersects with the center of the finished bearing cover 7. The thickness of the squeezing head 302 is less than the thickness of the step 701. After the positioning plate 2 is fixed, the second arc groove 303 of the squeezing plate 3 abuts against the right front wall of the bearing cover. After the squeezing plate 3 is locked by screws, the positioning and fixing effect on the circumferential outer wall of the bearing cover is formed, and a firm fixing effect is formed in cooperation with the strong magnetism of the powerful suction cup 1. The screws used to fix the squeezing plate 3 are arranged inside the oblong groove 301. The setting of the oblong groove 301 enables the squeezing plate 3 to move back and forth. When the outer diameter of the bearing cover blank 6 changes within the tolerance range, the change in the outer diameter can be compensated by moving the squeezing plate 3.

[0032] Working principle: In this embodiment, the finished bearing cover 7 is processed from the bearing cover blank 6. It is necessary to machine a step 701, a milling machine profile, and drill holes on the bearing cover blank 6. During machining and clamping, the bearing cover blank 6 is clamped. After machining, it becomes the finished bearing cover 7. In fact, they are the same product. The finished bearing cover 7 and the bearing cover blank 6 are names in different processing states. For the convenience of description in the following of this embodiment, they will all be described under the name of the bearing cover. The left wall of the finished bearing cover 7 abuts against the inner wall of the notch 501, and the notch 501 forms a positioning effect on the left wall of the bearing cover. The height of the baffle 5 protruding from the strong magnetic chuck 1 is less than the thickness of the step 701 to prevent the baffle 5 from interfering with the machining tool when machining the step 701. After the bearing cover abuts against the notch 501, the positioning plate 2 is placed behind the bearing cover and the first arc groove 201 is tightened against the rear wall of the bearing cover. Then, the positioning plate 2 is fixed by pressing the pressing plate 4. The rear positioning of the bearing cover is formed by the first arc groove 201 of the positioning plate 2. The thickness of the positioning plate 2 is less than the thickness of the step 701 to prevent the positioning plate 2 from interfering with the machining tool when machining the step 701. After the positioning plate 2 is fixed, the second arc groove 303 of the clamping plate 3 abuts against the right front wall of the bearing cover. After tightening the clamping plate 3 with screws, a positioning and fixing effect on the circumferential outer wall of the bearing cover is formed. Cooperating with the strong magnetism of the strong magnetic chuck 1, a firm fixing effect is formed. The screws used to fix the clamping plate 3 are arranged inside the long circular groove 301. The setting of the long circular groove 301 enables the clamping plate 3 to move back and forth. When the outer diameter of the bearing cover blank 6 changes within the tolerance range, the change in the outer diameter can be compensated by moving the clamping plate 3. After the clamping plate 3 is fixed, the strong magnetic chuck 1 is turned on, and a downward adsorption fixing force can be formed on the bearing cover through strong magnetism, avoiding the clamping failure caused by the upward movement of the bearing cover during machining.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
