Description

Technical Field

[0001] The utility model relates to the technical field of non-standard equipment, in particular to a cylinder block finishing production unit. Background Art

[0002] The cylinder barrel is an important component in an engine and usually works together with a piston. It provides a sealed space where fuel and air are mixed and burned, pushing the piston to move up and down, and then driving the crankshaft to rotate, ultimately converting into mechanical energy. The cylinder barrel is usually made of high-strength, high-temperature resistant and corrosion-resistant materials such as cast iron or aluminum alloy. During the production process of the cylinder barrel, four processes of precision boring and rolling the inner hole, deburring, cleaning, and welding the cylinder head need to be continuously processed. Currently, the existing equipment for the cylinder barrel production process is messy, reducing production efficiency. An unreasonable layout will lead to unsmooth material flow, increasing the handling distance and time, and reducing the production rhythm of the production line. In addition, a messy equipment layout may cause problems such as blocked safety channels and unsmooth emergency exits, increasing the risks of accidents such as fires and mechanical injuries.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are only for the purpose of describing specific implementations and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0018] Such as Figures 1 - 2As shown in the figure, a production unit for fine machining of cylinder blocks includes a transport line 1, a hole-turning station 2, a burnishing machine 3, an in-cylinder-hole inspection station 4, an outer-periphery inspection station 5, a cleaning station 6 and a cylinder-head welding station 7. The hole-turning station 2, the in-cylinder-hole inspection station 4, the outer-periphery inspection station 5 and a group of the cylinder-head welding stations 7 are sequentially arranged on one side of the transport line 1, and the burnishing machine 3, the cleaning station 6 and another group of the cylinder-head welding stations 7 are sequentially arranged on the other side of the transport line 1. The workpiece is grabbed by the transport line 1 and sequentially passes through the hole-turning station 2, the burnishing machine 3, the cleaning station 6, the in-cylinder-hole inspection station 4, the outer-periphery inspection station 5 and the cylinder-head welding station 7. Specifically, in this embodiment, the transport line 1 is arranged in a linear layout, linearly grabs and transports the workpiece, and sequentially feeds the workpiece into the hole-turning station 2, the burnishing machine 3, the cleaning station 6, the in-cylinder-hole inspection station 4, the outer-periphery inspection station 5 and the cylinder-head welding station 7 for processing. The hole-turning station 2 is used to turn holes at both ends of the cylindrical workpiece and cut internal threads. Here, we select numerically controlled machine tools for turning, specifically Shenyang Machine Tool, Youjia CNC Lathe, Baoji Machine Tool, Doosan CNC Lathe, etc. The burnishing machine 3 is used to scrape and burnish the inner hole turned by the workpiece. The cleaning station 6 can remove iron chips, impurities, etc. adhering to the surface of the workpiece during processing. The in-cylinder-hole inspection station 4 and the outer-periphery inspection station 5 are respectively used to detect whether the inner diameter of the inner hole turned by the workpiece is within the tolerance range and whether there are defects on the outer periphery of the workpiece. If so, the workpiece needs to be removed from the transport line 1 to ensure that the processing quality of the workpiece meets the standards. The workpiece with good inspection results is then transported by the transport line 1 to the cylinder-head welding station 7. Since the welding station has a long operation time, we have arranged two cylinder-head welding stations 7 on both sides of the transport line 1 for double-station operation to improve the welding efficiency and match the production rhythm of the upstream stations. Our production line layout is linear, the workpiece processing and transfer are smooth, matching the production rhythm and improving the operation efficiency; and the transport line is set between the processing equipment, which is convenient for the transport line to transport the workpiece for double-sided processing and saves the floor area in the workshop.

[0019] As Figures 1 - 2 shown, the transport line 1 includes a track 11 and a grasping robotic arm 12. The track 11 is arranged in a straight line, and the grasping robotic arm 12 is movably arranged on the track 11. Specifically, the lower end of the robotic arm 12 is movably clamped to the track 11, so that the robotic arm 12 can make reciprocating linear displacement along the track 11 under the drive of external forces such as drive motors, lead screws, cylinders and other components to transport the workpiece. It can be understood that in order to make the robotic arm 12 grasp the workpiece firmly, a tooling matching the workpiece can be installed at the output end of the robotic arm 12. The robotic arm 12 adopts multi-axis linkage and is rotatable, which is convenient for placing the workpiece in other stations on both sides of the track 11 for processing operations.

[0020] As Figures 1 - 2As shown in the figure, it further includes a fence 100, and the fence 100 is arranged around the periphery of the transportation line 1, the vehicle hole station 2, the tumbling machine 3, the cylinder inner hole detection station 4, the cylinder outer periphery detection station 5, the cleaning station 6 and the cylinder head welding station 7. Specifically, the fence 100 is used to enclose each station, playing a protective role to prevent other workers in the workshop from straying in, reducing the probability of safety accidents and ensuring the safety of employees' production operations.

[0021] As Figure 3 shown in the figure, the cylinder inner hole detection station 4 includes a workbench 41, a lead screw assembly 42, a slide plate 43, a plurality of holding clamps 44, guide rails 45, a fixed baffle 46, a movable baffle 47 and a cylinder 48. The lead screw assembly 42 is installed in the workbench 41. The surface of the workbench 41 is provided with a groove 411. Two guide rails 45 are installed in the groove 411 side by side at intervals. The lower end of the slide plate 43 is movably connected to the guide rails 45. The lead screw assembly 42 drives the slide plate 43 to make a reciprocating linear motion along the guide rails 45. A second guide rail 431 is arranged on the slide plate 43 along its extending direction. A plurality of the holding clamps 44 are installed on the slide plate 43 side by side at intervals. The holding clamps 44 are arranged on both sides of the second guide rail 431. The fixed baffle 46 is detachably installed at the right end of the second guide rail 431. The movable baffle 47 is movably clamped at the left end of the second guide rail 431. The cylinder 48 is installed below the slide plate 43, and the output end of the cylinder 48 is connected to the movable baffle 47. Specifically, in this embodiment, the workbench 41 is hollow to facilitate the installation of electrical components inside. Its surface is provided with two grooves 411, and the guide rails 45 are installed inside the grooves 411. The lower end of the slide plate 43 is movably clamped to the guide rails 45, so that the lead screw assembly 42 can drive the slide plate 43 to reciprocate along the guide rails 45 to carry workpieces, facilitating their detection. It is far away from the original production line to ensure the safety of operators. A plurality of holding clamps 44 and a second guide rail 431 are integrated on the slide plate 43. The holding clamps 44 are arranged on both sides of the second guide rail 431 in a mirror-symmetrical manner. The workpiece is placed on the holding clamps 44 through the transportation line 1. A fixed baffle 46 and a movable baffle 47 are respectively arranged at both ends of the second guide rail 431. It can be understood that in the initial state, the distance between the fixed baffle 46 and the movable baffle 47 is greater than the length of the cylinder barrel, which is convenient for the manipulator to place the cylinder barrel on the holding clamps without bumping into the fixed baffle 46 and the movable baffle 47, avoiding damage. Further, when the cylinder 48 is connected to the movable baffle 47 and drives the movable baffle 47 to displace along the second guide rail 431, it can abut against one end of the workpiece and drive the workpiece to synchronously displace on the holding clamps 44 until the other end of the cylinder barrel abuts against the fixed baffle 46, positioning and clamping the cylinder barrel, and then the inner and outer diameters and length of the workpiece can be measured to ensure that the measurement accuracy meets the standard and improve the measurement efficiency.

[0022] As Figure 4As shown in the figure, the outer periphery inspection station 5 of the cylinder body includes a scanning head 51, a bottom support 52 and a sliding frame 53. The scanning head 51 is installed at the output end of the sliding frame 53, and the bottom support 52 is arranged directly below the scanning head 51. Specifically, the transport line 1 grabs the workpiece and places it into the bottom support 52. The scanning head 51 is displaced driven by the sliding frame 53 to take pictures of the surface of the workpiece. The background software conducts image comparison to confirm whether there are defects such as pits on the surface of the workpiece that do not meet the factory standards. If so, it is removed from the transport line 1 to ensure that the quality of the processed product meets the standards.

[0023] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
