By introducing components such as transport slide, traction block, and positioning cylinder, the automated movement from the pressing position to the robot unloading position is realized, the unloading process is optimized, and the efficiency, accuracy and reliability of large steel spring assembly are improved. Moreover, the equipment has a simple structure and low maintenance cost and operation difficulty.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a high-speed train steel spring assembly press with automatic feeding function, including a frame and an assembly press, a transport slide, and a traction block mounted on the frame; the assembly press includes a base and a sliding trolley mounted on the base; the transport slide includes a rodless cylinder, a slide mounted on the rodless cylinder, and a positioning cylinder mounted below the slide.

[0007] The assembly press and the traction block are located on one side of the transport slide. The traction block is connected to the trolley and is located between the assembly press and the transport slide.

[0008] The trolley and traction block move along the base from the loading position to the pressing position. The positioning cylinder engages with the through hole on the traction block, and the rodless cylinder drives the slide to move the trolley and traction block to the robot unloading position.

[0009] In one embodiment, the assembly press further includes a top plate, a hydraulic cylinder, a bottom plate, and guide columns;

[0010] The guide column is located between the top plate and the bottom plate. The press-fitting position is located below the center of the top plate. The base is installed through the guide column, and the hydraulic cylinder is located below the base to push the base up and down.

[0011] In one embodiment, the assembly press further includes limiting strips disposed on both sides of the base; rollers disposed at the bottom of the trolley move along the limiting strips above the base.

[0012] In one embodiment, the transport slide further includes a limiting block; the limiting block is disposed on the side of the slide near the robot unloading position, and is used to limit the position of the positioning cylinder; the positioning cylinder is disposed on the side of the slide near the pressing position.

[0013] In one embodiment, the vertical distance between the straight line where the limiting block is located and the positioning cylinder is the vertical distance between the through hole opened on the traction block and the edge of the traction block 5 near the robot's unloading position.

[0014] In one embodiment, the transport slide further includes a slider, a guide rail, and a guide rail support;

[0015] The guide rail bracket is located inside the frame, and two sets of sliders are respectively located on both sides of the slide table and can move along the guide rail. The guide rail is mounted on the guide rail bracket.

[0016] In one embodiment, the transport slide also includes buffers, with two sets of buffers disposed inside the frame and located beside the head and tail ends of the rodless cylinder, respectively, for buffering the positioning cylinder.

[0017] In one embodiment, a locking mechanism is also included, which is disposed on the frame and located on one side of the traction block, for locking the traction block and the trolley.

[0018] In one embodiment, the locking mechanism includes a locking cylinder, a limiting device, a position sensor, and an L-shaped plate;

[0019] The position sensor and L-shaped plate are mounted on the frame, with the position sensor closer to the loading position. The position sensor is used to sense the position of the traction block. The locking cylinder is mounted on the L-shaped plate and is connected to the limit device. The locking cylinder drives the limit device to move forward to lock and move backward to unlock the traction block.

[0020] In one embodiment, the traction block has two through holes along its width, through which the trolley is connected.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention provides a high-speed train steel spring assembly press with automatic unloading function. The equipment has a simple structure. After the steel springs placed on the sliding trolley are assembled under the press, a rodless cylinder drives a slide table to automatically move the trolley to the robot unloading position, realizing an integrated pressing-unloading process and reducing process changeover time. Specifically, the rodless cylinder driving the slide table automatically moves the traction block connected to the positioning cylinder on the slide table and the trolley connected to the traction block from the pressing position to the robot unloading position, reducing manual intervention and improving production efficiency and automation. The fit between the positioning cylinder and the through hole on the traction block, as well as the precise movement of the trolley on the base, ensures the positioning accuracy between each station. The steel springs can be accurately placed in the designated position during assembly and unloading, reducing assembly errors and quality problems caused by inaccurate positioning.

[0023] Furthermore, the limit bar provides a clear movement path for the trolley, ensuring that the trolley moves along a predetermined trajectory above the base, thus improving the accuracy and reliability of the operation.

[0024] Furthermore, the vertical distance between the line where the limiting block is located and the positioning cylinder is the vertical distance between the through hole on the traction block and the edge near the unloading position of the robot. The limiting block ensures the accurate position of the positioning cylinder during the movement process, prevents the positioning cylinder from exceeding the predetermined range, and ensures the precise fit between the positioning cylinder on the slide and the through hole of the traction block.

[0025] Furthermore, the slider moves along the guide rail, ensuring smooth movement of the slide table, reducing resistance and friction during movement, and improving the operating efficiency of the equipment.

[0026] Furthermore, the buffer plays a buffering role in the driving process of the rodless cylinder, reducing the impact and vibration of the positioning cylinder during start-up and stop, and extending the service life of the equipment.

[0027] Furthermore, the locking mechanism locks the traction block and the sliding carriage after they have moved to the designated position, ensuring the accuracy of the pressing position during pressing, preventing movement or offset during the pressing process, and ensuring the stability of the pressing.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings:

[0046] Referring to Figures 1 and 3, this utility model provides a high-speed train steel spring assembly press with automatic feeding function, which mainly consists of a frame 1, an assembly press 2, a transport slide 3, a locking mechanism 4, and a traction block 5. Specifically, the EMU steel spring assembly press equipment with automatic unloading function mainly includes a frame 1 and an assembly press 2, a transport slide 3, and a traction block 5 mounted on the frame 1. The assembly press 2 includes a base 2-3 and a sliding carriage 2-2 mounted on the base 2-3. The transport slide 3 includes a rodless cylinder 3-1, a slide 3-2 mounted on the rodless cylinder 3-1, and a positioning cylinder 3-3 mounted below the slide 3-2. The assembly press 2 and the traction block 5 are located on one side of the transport slide 3. The traction block 5 is connected to the sliding carriage 2-2 and is located between the assembly press 2 and the transport slide 3. The sliding carriage 2-2 and the traction block 5 move along the base 2-3 from the loading position to the pressing position. The positioning cylinder 3-3 cooperates with the through hole opened on the traction block 5. The rodless cylinder 3-1 drives the slide 3-2 to move the sliding carriage 2-2 and the traction block 5 to the robot unloading position.

[0047] The assembly press 2 mainly consists of a top plate 2-1, a sliding trolley 2-2, a base 2-3, a hydraulic cylinder 2-4, a bottom plate 2-5, a limit bar 2-6, and a guide column 2-7. The transport slide 3 mainly consists of a rodless cylinder 3-1, a slide 3-2, and a positioning cylinder 3-3. This equipment not only has the function of combining and pressing inner and outer steel springs, but also has the functions of manual feeding and automatic robot unloading. It can be integrated into the steel spring maintenance production line and meet the functional requirements of the steel spring maintenance production line for the combined press. The frame 1 is integrally welded from square tubes, and the overall structure is cuboid.

[0048] One end of the frame 1 is a manual loading position, and the other end is a robot unloading position. Starting from the manual loading position and ending at the robot unloading position, the frame 1 is sequentially equipped with an assembly press 2, a traction block 5, and a transport slide 3. The assembly press 2 is connected to the traction block 5, which is located between the assembly press 2 and the transport slide 3. A locking mechanism 4 is located on one side of the assembly press 2 and the traction block 5. The assembly press 2 and the transport slide 3 are recessed and installed inside the frame 1.

[0049] Referring to Figures 2, 4, 5, and 12, the assembly press 2 includes a top plate 2-1, a sliding carriage 2-2, a base 2-3, a hydraulic cylinder 2-4, a bottom plate 2-5, a limit bar 2-6, and a guide column 2-7.

[0050] The pressing position is located below the center of the top plate 2-1. The guide column 2-7 is located between the top plate 2-1 and the bottom plate 2-5. The base 2-3 is installed through the guide column 2-7. The sliding trolley 2-2 has four pulleys and can slide on the base 2-3. The hydraulic cylinder 2-4 is located below the base 2-3 and can push the base 2-3 up and down. The assembly press 2 can combine and press the inner and outer springs of the steel spring. The sliding trolley 2-2 can be extended for manual hoisting of the steel spring to the assembly table, and then slide to the bottom of the assembly press 2 for assembly. The limiting strip 2-6 is located on both sides of the base 2-3. The rollers at the bottom of the sliding trolley 2-2 move along the limiting strip 2-6 above the base 2-3.

[0051] Referring to Figures 8 to 11, the transport slide 3 includes a rodless cylinder 3-1, a slide 3-2, a positioning cylinder 3-3, a limit block 3-4, a slider 3-5, a guide rail 3-6, and a buffer 3-7.

[0052] Positioning cylinder 3-3 is located below slide 3-2, which is mounted on rodless cylinder 3-1. The transport slide 3 allows the steel spring to switch between the pressing position and the robot unloading position. Before the transport slide 3 is pneumatically activated, positioning cylinder 3-3 extends from below slide 3-2 and engages with the through hole on traction block 5, driving the trolley 2-2 to move linearly. Two limiting blocks 3-4 are located on slide 3-2 and are on the same straight line. Limiting blocks 3-4, in conjunction with traction block 5, restrict the position of positioning cylinder 3-3. The vertical distance between the line containing limiting blocks 3-4 and positioning cylinder 3-3 is the vertical distance between the through hole on traction block 5 and the edge of traction block 5 closest to the robot unloading position. Positioning cylinder 3-3 is closer to the pressing position than limiting blocks 3-4.

[0053] The transport slide 3 is recessed and installed in the frame 1. The two guide rail supports in the transport slide 3 are respectively installed on the inner sides of the frame 1. The guide rail 3-6 is installed on the guide rail supports. There are two sets of sliders 3-5, a total of 4 sliders 3-5, which are respectively installed on both sides of the slide 3-2 and can move along the guide rail 3-6. A buffer 3-7 is installed at each of the front and rear ends of the frame 1. The two buffers 3-7 are used to buffer the positioning cylinder 3-3.

[0054] Referring to Figures 3, 4, 6, 7, 8, and 14, the locking mechanism 4 includes a locking cylinder 4-1, a limiting device 4-2, a position sensor 4-3, and an L-shaped plate 4-4. The limiting device 4-2 can be a pin.

[0055] The locking mechanism 4 is located near one end of the assembly press 2 and the traction block 5, on the frame 1 and on one side of the traction block 5, and is used to lock the traction block 5 and the sliding carriage 2-2.

[0056] Position sensor 4-3 is closer to the loading position than locking cylinder 4-1. Position sensor 4-3 and L-shaped plate 4-4 are set on frame 1. Position sensor 4-3 can sense the position of traction block 5. Locking cylinder 4-1 is set on L-shaped plate 4-4. Locking cylinder 4-1 is connected to limiting device 4-2. Limiting device 4-2 can be inserted into a hole on the side of traction block 5. Locking cylinder 4-1 can drive limiting device 4-2 forward to lock traction block 5 and backward to unlock traction block 5.

[0057] Referring to Figures 12 and 13, a through hole is provided through the traction block 5 along the height direction. This through hole is used to cooperate with the positioning cylinder 3-3 for traction. The vertical distance between the through hole on the traction block 5 and the edge of the traction block 5 near the robot's unloading position is equal to the vertical distance between the straight line where the limit block 3-4 is located and the positioning cylinder 3-3.

[0058] The traction block 5 has two through holes along its width, through which the sliding carriage 2-2 is connected. The side of the traction block 5 has two holes that cooperate with the locking mechanism 4.

[0059] Referring to Figure 1, the EMU steel spring assembly press equipment with automatic unloading function has a manual loading position on one side and a robot unloading position on the other. The assembly press 2 can combine and press the inner and outer springs of the steel spring. The sliding trolley 2-2 can be extended for manual lifting of the steel spring to the assembly table, and then slide to the pressing position directly below the assembly press 2 for assembly. The transport slide 3 can realize the switching of the steel spring from the pressing position to the robot unloading position. Before the transport slide 3 is pneumatically operated, the positioning cylinder 3-3 under the slide 3-2 extends to drive the sliding trolley 2-2 to move, realizing the linear movement of the sliding trolley 2-2.

[0060] The position sensor 4-3, locking cylinder 4-1, oil cylinder 2-4, rodless cylinder 3-1, positioning cylinder 3-3 and other components in the above-mentioned EMU steel spring assembly press equipment with automatic feeding function are connected to the control system and are controlled by the control system, which can be a PLC system.

[0061] The operation process of the above-mentioned EMU steel spring assembly press with automatic feeding function is as follows:

[0062] S1: The traction block 5 and the sliding carriage 2-2 slide on the base 2-3 to the loading position. The steel spring is manually hoisted onto the sliding carriage 2-2 and then slid to the center of the top plate 2-1. The position sensor 4-3 senses the position of the traction block 5 and transmits a signal to the control system. The control system controls the locking cylinder 4-1 to drive the limit device 4-2 forward to lock the traction block 5. The steel spring is pressed at the pressing position.

[0063] S2: After pressing is completed, the control system controls the locking cylinder 4-1 to drive the limit device 4-2 to move backward and unlock the traction block 5. At this time, the slide 3-2 is in a position close to the pressing position. Before the transport slide 3 is pneumatically propelled, the control system controls the positioning cylinder 3-3 under the slide 3-2 to extend and cooperate with the through hole on the traction block 5. The control system controls the rodless cylinder 3-1 to drive the traction block 5 and the sliding car 2-2 to move to the unloading position, and the robot automatically grabs and unloads the material.

[0064] Some existing assembly presses only have the function of assembling steel springs and cannot realize automatic robotic gripping and unloading. However, the existing assembly press, combined with the equipment of this utility model, features a sliding carriage 2-2 and a traction block 5 that move along the base 2-3, making the loading process smoother. Workers do not need to perform complex operations to adjust the position of the steel springs; they only need to place the steel springs in the designated positions, and the equipment can move to the pressing position for assembly, reducing the difficulty and labor intensity of manual loading. Unloading from the pressing position to the unloading position reduces the manual unloading step, greatly improving the unloading speed and thus improving the production efficiency of the entire maintenance production line. The rodless cylinder 3-1 drives the slide table 3-2, which moves the sliding carriage 2-2 on the slide table 3-2 to the pressing position. The sliding carriage 2-2 and the traction block 5 work together to move the steel spring to the robot unloading position, enabling the existing equipment to work collaboratively with the robot on the production line to achieve automatic unloading after steel spring assembly, meeting the requirements of the maintenance production line for automated production without excessive modification costs.

[0065] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
