Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical processing, in particular to a hydraulic oil passage block process equipment system and an automatic production line. BACKGROUND

[0002] The oil passage block is an important part in the hydraulic system, and its machining precision determines the stable operation of the hydraulic system. The oil passage block blank is a regular square part with simple machining process. At present, the production and processing of the oil passage block are mostly manual operation of the machine tool, using a simple positioning and clamping method, and multiple positioning and clamping are required in one machining process, which leads to poor machining precision of the oil passage block, and often results in low yield due to insufficient surface precision and large roundness error of the oil passage hole. Therefore, it is imperative to realize the automatic production and high-precision positioning machining of the oil passage block.

[0003] A kind of automobile hub process equipment system and intelligent clean and precision machining production line are disclosed in Chinese patent (publication number: CN113953542B), mainly used for flexible production of hub and other disc parts, and not applicable to square parts such as oil passage block. A kind of brick blank stacking device is disclosed in Chinese patent (publication number: CN103434848B), which uses a buffer device to buffer the impact force of the slider when the positioning device is impacted by the steam curing vehicle, effectively relieving the impact force on the cylinder and effectively prolonging the service life of the cylinder. However, the stacking device operates independently and requires additional feeding and discharging devices, increasing the cost of additional equipment. A hydraulic oil passage block positioning and fixing device is disclosed in Chinese patent application (publication number: CN110805586A), which can adjust the position of the oil passage block. However, it is only suitable for the installation environment of the hydraulic oil passage block and cannot be used as positioning and machining equipment during production and processing. A punching positioning mechanism for hydraulic oil passage block is disclosed in Chinese patent (publication number: CN213052838U), which realizes positioning and adjustment of the punching process of the oil passage block by setting a turntable, a locking mechanism, an auxiliary positioning mechanism, a first shaft and a special-shaped groove. However, it can only be applied to the punching field of the oil passage block and needs to be replaced with a clamp for milling operation on the surface of the oil passage block, which cannot meet the demand for multiple processing methods of the oil passage block in flexible processing. In summary, the existing oil passage block processing production has the technical bottleneck of low efficiency and insufficient positioning and machining precision, and the known technology cannot realize the automatic production of the oil passage block and cannot meet the demand for processing efficiency and precision of the oil passage block.

Specifically, the positioning device I-2-9 limits the degrees of freedom of the workpiece, the cylinder I-2-5 installed on the slider of the guide rail I-2-10 drives the chuck I-2-4 to press tightly on the upper surface of the workpiece. The motor I-2-6 installed on the slider carried by the guide rail I-2-10 drives the sprocket I-2-7 to move the slider along the guide rail I-2-10, thereby driving the cylinder I-2-5 and the chuck I-2-4 installed on the slider to move, and the brake block I-2-8 is used to realize mechanical braking and positioning of the slider.

[0055] As shown, Figure 11 The base I-2-1 has two layers in total, and part of the upper layer of the base I-2-1-1 is in a hollow structure, which is used to install the tensioning wheel I-2-2 and the chain I-2-3, and at the same time prevents the accumulation of cutting chips.

[0056] The support supports the bottom surface of the workpiece, and is arranged on the upper layer of the base and includes at least three first supporting pins, the top ends of all the first supporting pins are coplanar and serve as a common contact and bearing surface for bearing the workpiece. In this embodiment, the first supporting pins are three supporting pins I-2-1-2 installed at the center position of the upper layer of the base I-2-1-1, which are used for positioning the workpiece and mainly limit the movement of the workpiece along the Z-axis and the rotation of the workpiece along the X-axis and the Y-axis. The upper layer of the base I-2-1-1 is provided with through holes I-2-1-3 for installing the positioning device I-2-9, and the through holes I-2-1-3 are in two groups and are diagonally arranged, each group has three through holes I-2-1-3, and the positioning devices I-2-9 installed in the two through holes I-2-1-3 in the same group are used to contact one side surface of the workpiece, and the positioning device I-2-9 installed in the other through hole I-2-1-3 in the same group is used to contact the adjacent side surface.

[0057] As shown, Figure 12 ,Figure 13 As shown, the positioning device I-2-9 includes a cylinder I-2-9-1, a flange I-2-9-2, a guide rod I-2-9-3, a spring I-2-9-4 and a supporting pin I-2-9-5.

[0090] The robot carries the oil passage block I-1 to the unloading position II-4-2, the unloading and loading robot II-2 carries the rack II-1-11 from the rack placing table II-5 to the bearing table II-3-5, and carries the oil passage block I-1 from the unloading position II-4-2 to the rack II-1-11. The bearing table II-3-5 is driven by the air cylinder II-3-3 to the intermediate position of the stacking device II-1, the Z-axis ball screw II-1-1 drives the bearing support II-1-10 to move between the upper surface of the bearing table II-3-5 and the lower surface of the rack, the X-axis ball screw II-1-2 drives the outer frame on both sides to move in the center, the Z-axis sliding block II-1-7 limits the rack II-1-11, the Z-axis ball screw II-1-1 drives the bearing support II-1-10 to move upwards and contact the bottom surface of the lowermost rack II-1-11, the bearing support II-1-10 moves upwards, and the rack II-1-11 moves upwards along the Z-axis guide rail II-1-6. The system determines whether the preset stacking quantity is reached, if not, the above operation is executed in a loop, if the preset stacking quantity is reached, the bearing support II-1-10 lowers the rack II-1-11 to the stacking table II-1-12, the processed oil passage block I-1 and the rack II-1-11 are carried away, and the unloading is completed.

[0091] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
