Description

Technical Field

[0001] This utility model relates to the field of crankcase machining technology, and in particular to a composite machine tool for crankcase machining. Background Technology

[0002] The lower part of the cylinder block, specifically designed to mount the crankshaft, is called the crankcase. The crankcase consists of two parts: the upper crankcase and the lower crankcase. Together, they support the crankshaft and are one of the key components of the engine. After production, the crankcase undergoes meticulous secondary machining, including boring and grinding, to ensure that its internal dimensions, shape, and positional accuracy meet design requirements, thus making it a qualified finished product. These machining processes typically require high-precision machine tools to ensure the crankcase's machining quality and production efficiency.

[0003] Existing machine tools generally employ clamping devices to fix workpieces during machining to ensure stability and accuracy. However, traditional clamping methods suffer from low clamping efficiency. Specifically, each time a machine tool runs, it can typically only clamp and process one workpiece. This single-workpiece clamping mode limits the machine tool's processing capacity, making it difficult to improve overall processing efficiency. Utility Model Content

After one workpiece is processed, the connecting frame is moved above the other workpiece for processing. During this process, the processed workpiece is removed and replaced with an unprocessed workpiece, which greatly reduces the time wasted when changing workpieces and improves the processing efficiency. Furthermore, the baffle plate of the second cylinder descends, blocking the movable opening and preventing debris generated during processing from splashing outside the connecting frame, which could injure the operator's hand when clamping the workpiece on the other side.

The left end of the ball screw 7 is fixedly fitted into the through hole. A motor 10 is fixedly connected to the left side of the left side plate 6 near the top. The shaft of the motor 10 is fixedly connected to the left end face of the ball screw 7. The front and rear sides of the connecting plate 9 are movably fitted with first guide rods 11. The left and right end faces of the first guide rods 11 are fixedly connected to the opposing faces of the two side plates 6 respectively.

[0023] In order to process the workpiece inside the connecting frame 2, the processing component 3 includes a first cylinder 31, which is fixedly connected to the middle of the top surface of the inner wall of the connecting frame 2. The lower end of the first cylinder 31 is fixedly connected to a mounting plate 32, and the bottom of the mounting plate 32 is bolted to a drilling machine 33.

[0024] In order to clamp and fix the workpiece, the clamping assembly 4 includes two placement platforms 41. The two placement platforms 41 are respectively fixedly connected to the left and right sides of the top surface of the base 1. The right placement platform 41 is located inside the connecting frame 2. The left and right sides of the top surface of each placement platform 41 are fixedly connected to a fixing plate 42. The middle of the fixing plate 42 is threaded with a screw 43. The end faces of the two opposing screws 43 on the left and right sides are threaded with clamping plates 44.

[0025] In order to prevent the clamping plate 44 from rotating with the screw 43, each clamping plate 44 has a second guide rod 45 fixedly connected to each of the four corners on the side near the fixed plate 42. One end of the second guide rod 45 is movably sleeved on the adjacent fixed plate 42.

[0026] In order to block the movable opening 5 and prevent the debris generated during processing from splashing onto the outside of the connecting frame 2, a second cylinder 12 is fixedly connected to the left and right sides of the top surface of the inner wall of the connecting frame 2. A connecting block 13 is fixedly connected to the lower end of each of the two second cylinders 12. A baffle 14 is fixedly connected to the opposite side of the bottom surface of each of the two connecting blocks 13. The opposite sides of the two baffles 14 are respectively in contact with the left and right sides of the inner wall of the connecting frame 2.

[0027] To facilitate access to the interior of the connecting frame 2 for inspection and replacement of components, a connecting door 15 is connected to the front hinge of the connecting frame 2. An observation window 16 is fixedly connected to the middle of the connecting door 15, and an observation glass 17 is fixedly nested inside the observation window 16.

[0028] To facilitate the operation of the electrical components on the control device, a control panel 18 is fixedly connected to the front side of the outer wall of the connecting frame 2. The control panel 18 is electrically connected to the motor 10, the first cylinder 31, and the second cylinder 12.

[0029] Working principle: When using this utility model, first open the connecting door 15, then place the workpiece on the right-side placement platform 41, and twist the screw 43 to move the two clamping plates 44 towards each other to clamp and fix the workpiece. Close the connecting door 15, then the first cylinder 31 pushes the mounting plate 32 down, and the mounting plate 32 pushes the drilling machine 33 down, so that the drilling machine 33 can process the workpiece. Since the drilling machine 33 and the mounting plate 32 are bolted together, they can be disassembled and reassembled. Depending on the actual situation, the drilling machine 33 can be replaced with a grinding machine. Alternatively, when grinding the workpiece on the right-side placement table 41 using other processing equipment, the operator can place the workpiece on the left-side placement table 41 and fix it in place. After the workpiece on the right-side placement table 41 is processed, the motor 10 drives the ball screw 7 to rotate. The rotation of the ball screw 7 causes the ball nut 8 to move to the left. The ball nut 8 drives the connecting plate 9 to move to the left, and the connecting plate 9 drives the connecting frame 2 to move to the left side of the top of the base 1. The workpiece on the left side is then placed on the outside, and the processing group... Part 3 then processes the workpiece on the left. During this time, the operator can remove the processed workpiece from the right-side placement table 41 and replace it with an unprocessed workpiece. In this way, two workpieces can be clamped and fixed at the same time. After one workpiece is processed, the connecting frame 2 is moved above the other workpiece. During this time, the processed workpiece is removed and replaced with an unprocessed workpiece, which greatly reduces the time wasted when changing workpieces and improves the processing efficiency of workpieces. When preparing to process the workpiece in the connecting frame 2, the second cylinder 12 is activated. The second cylinder 12 pushes the connecting block 13 down, and the connecting block 13 drives the baffle 14 down, so that the baffle 14 blocks the movable opening 5, preventing the debris generated during processing from splashing to the outside of the connecting frame 2, which could cause the operator's hand to be injured by the splashed debris when clamping the workpiece on the other side. When the connecting frame 2 needs to be moved, the second cylinder 12 pulls the baffle 14 up, exposing the movable opening 5, so that the connecting frame 2 will not be blocked by the placement table 41 when moving through the movable opening 5.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
