Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing and processing, and in particular to a hydraulically mounted riveting inspection device. Background Technology

[0002] In the automobile manufacturing process, the manufacturing quality of hydraulic mounts has a significant impact on the vehicle's ride stability, comfort, and overall performance. After assembly, the riveting process at the ends of the hydraulic mount's outer shell is a crucial step in ensuring its sealing and structural strength, ultimately affecting the performance of the entire hydraulic mount.

[0003] With the continuous development of the automotive industry, the requirements for the quality and production efficiency of hydraulic suspension products are becoming increasingly higher. To meet this market demand, automated riveting equipment is now available, such as the Chinese patent application "A riveting assembly fixture for automotive hydraulic suspension parts and its usage method," application number: CN201210151787.2, which discloses a fixture base plate, a workpiece support frame, a clamping head, and a digital display electric torque gun. The workpiece support frame is installed in the middle of the upper surface of the fixture base plate. A cylinder mounting bracket is vertically installed on the left side of the workpiece support frame, and a guide clamping cylinder is horizontally mounted and fixed on the cylinder mounting bracket. The piston rod of the guide clamping cylinder extends to the right and connects to the clamping head. The clamping head has guide rods symmetrically arranged on both sides of its rear end, which pass through the through holes on both sides of the cylinder mounting bracket. On the tooling base plate on the right side of the workpiece support bracket, four guide rail brackets are evenly and symmetrically installed parallel to its long side. The two opposing guide rail brackets are equipped with ball linear guide rails. An electric torque gun moving frame is vertically installed on the two ball linear guide rails. Two digital display electric torque guns are horizontally and side by side installed in the middle of the electric torque gun moving frame. Two positioning rods are symmetrically and horizontally installed on the left side wall of the electric torque gun moving frame. An actuating cylinder is connected and installed at the lower right end of the electric torque gun moving frame.

[0004] The production process of hydraulic suspension typically involves multiple steps, including riveting and inspection. However, these steps are often scattered across different equipment, leading to low production efficiency and potential assembly errors and product damage during process transitions. Furthermore, existing inspection methods are mostly manual, resulting in low accuracy and difficulty in ensuring product quality stability. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a hydraulically suspended riveting inspection device, which effectively solves the problems of dispersed processes, low efficiency and large space occupation in the prior art by integrating multiple processes into the same frame and adopting an automated transfer mechanism.

[0006] The technical solution adopted in this application is: a hydraulically mounted riveting inspection device, which belongs to the field of automotive parts manufacturing and processing. It includes a frame, on which a first riveting station, a second riveting station, an outer diameter inspection station, a height inspection station, and an unloading station are sequentially arranged. A transfer mechanism is provided at the front end of the frame. The transfer mechanism includes a moving component and a base strip. The base strip is mounted on the moving component, and multiple clamping cylinders are provided on the base strip. Each clamping cylinder is connected to a gripper assembly. The operation of the clamping cylinders causes the gripper assembly to open or close. The operation of the moving component drives the gripper to move between two adjacent stations. One of the gripper assemblies connects to the feeding device and the first riveting station.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, it integrates multiple processes such as the first riveting station, the second riveting station, the outer diameter detection station, the height detection station, and the unloading station onto the same frame, changing the previous situation where the processes were scattered across different equipment. Hydraulic suspension eliminates the need for frequent transfers between different devices, avoiding time losses during transfers, making the entire production process more compact and continuous, and greatly improving production efficiency.

[0008] Secondly, the transplanting mechanism enables the automatic and continuous transfer of the hydraulic suspension between different workstations. Clamping cylinders drive the gripper assembly to precisely grasp and move the hydraulic suspension, while the moving assembly ensures that the gripper can move stably and quickly between adjacent workstations. This automated transfer method reduces manual operation, avoids the inefficiency and errors that can result from manual handling, and further improves the smoothness and efficiency of the production process.

[0009] Furthermore, because all processes are tightly integrated on the same equipment, hydraulic suspension avoids assembly errors caused by inter-equipment transfers during process transitions. There is no need to worry about the impact of shaking or collisions during transfers on riveting quality, thus ensuring the quality stability of the product at each critical stage and improving the overall product quality.

[0010] Finally, integrating multiple processes onto a single rack significantly saves workshop floor space compared to a scattered equipment layout. Within a limited production space, more production equipment or additional production steps can be arranged, improving workshop space utilization and helping companies optimize production layout and reduce production costs.

[0011] In some embodiments of this application, there is a predetermined distance between two adjacent clamping cylinders, and multiple gripper assemblies correspond one-to-one with the first riveting station, the second riveting station, the outer diameter detection station, the height detection station, and the unloading station.

[0012] This design ensures that the gripper assembly can accurately transfer materials between each workstation, avoiding material collisions or damage caused by inaccurate gripper positioning. At the same time, the one-to-one correspondence layout improves equipment operating efficiency, reduces the additional time lost due to gripper assembly position adjustments, and further enhances the smoothness and automation of the production process.

[0013] In some embodiments of this application, a base plate is installed at the bottom of the first riveting station, and a mounting base is provided on the base plate. The mounting base is detachably connected to the fixing fixture. The top surface of the mounting base is the mounting reference surface. The top of the fixing fixture matches the hydraulic suspension to be tested, and the bottom of the fixing fixture is inserted into the mounting base.

[0014] The base plate and mounting base provide stable support and a precise mounting reference for the fixed fixture, ensuring that the hydraulic mount maintains a stable position during riveting, thereby improving the accuracy and quality of riveting. The detachable connection design facilitates the replacement of different models of fixed fixtures, enhancing the versatility and flexibility of the equipment and enabling it to adapt to hydraulic mounts of different sizes and shapes.

[0015] In some embodiments of this application, a drive electric cylinder is provided at the top of the first riveting station, and a rotary motor is provided at the rear side of the first riveting station. A connecting base is movably connected to the output shaft of the drive electric cylinder, and the output shaft of the rotary motor is connected to the connecting base through a connector. A riveting head is detachably installed on the connecting base. When the drive electric cylinder works, it drives the rotary motor and the connecting base to move downwards. When the rotary motor works, it drives the connecting base to rotate around the axis.

[0016] The combination of a drive cylinder and a rotary motor enables precise up-and-down movement and rotation of the riveting head, allowing for accurate riveting operations tailored to the specific requirements of the hydraulic mount. This design enhances the automation and precision of riveting, reduces errors caused by manual operation, and ensures the stability and consistency of riveting quality.

[0017] In some embodiments of this application, the structure of the second riveting station is the same as that of the first riveting station. The second riveting station can perform riveting on the other end of the hydraulic suspension in the same manner as the first riveting station, ensuring the consistency and symmetry of the riveting process at both ends.

[0018] In some embodiments of this application, a rotary cylinder is provided on one side of the base strip, and the rotary cylinder and the clamping cylinder are respectively located on both sides of the base strip. The output shaft of the rotary cylinder passes through the base strip and is connected to the clamping cylinder corresponding to the second riveting station. The operation of the rotary cylinder drives the clamping cylinder and the gripper assembly connected to it to rotate.

[0019] The first riveting station performs riveting on one end of the hydraulic suspension. Then, the hydraulic suspension is clamped and rotated by the gripper assembly before being placed in the second riveting station, where the other end of the hydraulic suspension is riveted. The rotary cylinder design enables precise rotation of the gripping cylinder and gripper assembly, improving the flexibility and accuracy of material transfer and further enhancing the automation and production efficiency of the equipment.

[0020] In some embodiments of this application, the unloading station includes a conveyor belt, one end of which is located near the height detection station, and the other end of which extends out of the frame. The conveyor belt is connected to a drive device, and the drive device drives the conveyor belt to perform transmission.

[0021] The conveyor belt design enables automated unloading via hydraulic suspension, reducing manual operation and improving unloading efficiency and stability. The continuous drive of the conveyor belt ensures a smooth unloading process, avoiding problems such as delayed unloading or material accumulation caused by manual operation.

[0022] In some embodiments of this application, one of the gripper assemblies operates to move a hydraulically suspended device at a gripping height detection station onto a conveyor belt.

[0023] The automated operation of the gripper assembly ensures that the hydraulic suspension can be accurately transferred from the height detection station to the conveyor belt, reducing errors and time losses caused by manual operation. This design further improves the automation level and production efficiency of the equipment, ensuring the continuity of the entire production process.

[0024] In some embodiments of this application, the unloading station includes an unloading assembly and a defective product frame, wherein the unloading assembly is disposed above the conveyor belt and the defective product frame is disposed on one side of the conveyor belt.

[0025] The design of the unloading assembly and defective product bins facilitates the timely screening and collection of non-conforming products, improving the efficiency and accuracy of quality control. This design helps to quickly identify and handle defective products, ensuring the quality stability of the final product while simplifying management processes on the production floor.
