Description

Technical Field

[0001] The utility model relates to the technical field of chain production, in particular to an automatic locking device of a chain processing punching machine. Background Art

[0002] In modern industrial production, chains are an important transmission and conveying component and are widely used in various fields. In the processing of chains, punch presses play a vital role. In order to ensure the stability and safety of punch presses when processing chains, automatic locking devices have emerged to help operators better process chains.

[0003] In traditional chain processing punch presses, manual locking operations are usually required. This method is not only inefficient, but also consumes a lot of manpower and may not completely lock the processing chain. When workers are performing the locking operation, the accuracy and reliability of manual locking are difficult to guarantee, which may cause the mold to loosen or the workpiece to shift, affecting the processing quality.

[0004] Therefore, it is urgent to provide an automatic locking device for a chain processing punch press to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned prior art and provide an automatic locking device for a chain processing punch press.

[0006] In order to solve the above technical problems, the present invention adopts a technical solution: to provide an automatic locking device for a chain processing punch press, comprising a processing bed, a mounting groove is opened at the center position of the top of the processing bed, a mounting plate is fixedly connected to the top of the processing bed near the mounting groove, and a slide rail is fixedly connected to the top of the mounting plate;

[0007] A mounting block is fixedly connected to the top of the processing bed near the slide rail, an active stretching mechanism is provided on the top of the mounting block, a passive stretching structure is provided on the other side of the top of the slide rail, a processing chain is installed on the top of the passive stretching structure, and a connecting rod is rotatably connected to the bottom of the passive stretching structure.

[0008] The utility model is further configured as follows: the active stretching mechanism includes a hydraulic cylinder installed on the top of the mounting block, the output end of the hydraulic cylinder is fixedly connected to a connecting head, the other end of the connecting head is rotatably connected to a Y-shaped rotating rod, one end of the Y-shaped rotating rod is rotatably connected to a first transmission rod, the other end of the first transmission rod is rotatably connected to a first slider, and the top of the first slider is fixedly connected to a first fixed block.

[0009] Through the above technical solution, in the initial state, the hydraulic rod in the hydraulic cylinder will extend to the maximum state, and the hydraulic rod will push the Y-shaped rotating rod to rotate around its installation point. During the rotation process, the Y-shaped rotating rod and the first transmission rod will be compressed, and the Y-shaped rotating rod will push the first slider to move through the first transmission rod. While the Y-shaped rotating rod rotates, the Y-shaped rotating rod will also drive the passive stretching structure to move synchronously through the connecting rod connected to its bottom until the two mechanisms reach a relatively close position. When the processing chain is placed behind the first fixed block and the passive stretching structure, the hydraulic cylinder is started to control the hydraulic rod to retract. During the retraction of the hydraulic rod, the hydraulic rod will pull back the Y-shaped rotating rod to rotate around its installation point, and the Y-shaped rotating rod will pull back the first transmission rod and the first slider, and the connecting rod at the bottom of the Y-shaped rotating rod will also drive the passive stretching structure to perform a synchronous pulling back movement. During the continuous pulling back process, the processing chains installed on the two mechanisms are straightened and locked, which is convenient for subsequent processing.

[0010] The present invention is further configured such that the inner wall of the first sliding block slides in contact with the outer wall of the slide rail.

[0011] Through the above technical solution, the first sliding block can only move along the direction specified by the slide rail and will not shake left and right or deviate from the track.

[0012] The utility model is further configured as follows: the passive stretching structure includes a second slider sliding on the outer wall of the slide rail, the top of the second slider is fixedly connected to a second fixed block, one side of the second slider is rotatably connected to a second transmission rod, and the other end of the second transmission rod is rotatably connected to a V-shaped rotating rod.

[0013] Through the above technical solution, when the active stretching mechanism is moving, the Y-shaped rotating rod inside the active stretching mechanism will drive the V-shaped rotating rod to move synchronously through the connecting rod. Because one end of the V-shaped rotating rod is connected to the connecting rod and the other end is connected to the second transmission rod, when the V-shaped rotating rod is stretched by the connecting rod and rotates, it will also drive the second transmission rod to move synchronously. Finally, the second transmission rod is used to realize the synchronous stretching movement of the second slider and the second fixed block, and the processing chain is straightened and locked.

[0014] The utility model is further configured as follows: the processing chain is installed between the first fixed block and the second fixed block.

[0015] Through the above technical solution, the processing chain is installed between the first fixed block and the second fixed block, which can provide stable support and guidance for the chain. The fixed block can limit the lateral movement of the chain so that it always runs along the predetermined path, avoiding the processing chain from deflecting, swinging or derailing.

[0016] The utility model is further configured as follows: the V-shaped rotating rod is rotatably connected to the inside of the slide rail.

[0017] Through the above technical solution, this connection method enables the V-shaped rotating rod to rotate flexibly in the slide rail, and fully utilizes the space, making the structure of the entire adjustment device more compact.

[0018] The utility model is further configured as follows: the connecting rod is installed between the Y-shaped rotating rod and the V-shaped rotating rod.

[0019] Through the above technical solution, the connecting rod plays a key connecting role between the Y-shaped rotating rod and the V-shaped rotating rod, and can effectively transmit power and motion. When the Y-shaped rotating rod rotates or moves, this motion can be transmitted to the V-shaped rotating rod through the connecting rod, thereby realizing the coordinated operation of the entire chain tension adjustment device.

[0020] The beneficial effects of the utility model are as follows:

[0021] 1. The utility model designs an active stretching mechanism and a matching passive stretching structure. After the processing chain to be processed is placed on the active stretching mechanism and the passive stretching structure, a hydraulic cylinder is used to provide pressure for the movement of the active stretching mechanism. During the pullback process of the active stretching mechanism, the active stretching mechanism will drive the passive stretching structure to perform synchronous pullback movement through the connecting rod until the processing chains on the active stretching mechanism and the passive stretching structure are fixed and straightened, which is convenient for subsequent work. The active stretching mechanism saves a lot of manpower and complicated processing steps, saves time and effort, and is simple to operate.

[0022] 2. The utility model installs a connecting rod between the active stretching mechanism and the passive stretching structure. When the active stretching mechanism pushes or pulls back, the passive stretching structure is driven by the connecting rod to move synchronously, so that both are in a synchronous movement state. In this way, the processing chains on the two will not be unevenly stressed during the tensioning process, resulting in breakage and safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0029] See also Figure 1 and Figure 2 An automatic locking device for a chain processing punch press comprises a processing bed 1, a mounting groove 2 is opened at the top center position of the processing bed 1, a mounting plate 3 is fixedly connected to the top of the processing bed 1 near the mounting groove 2, a slide rail 4 is fixedly connected to the top of the mounting plate 3, and a mounting block 5 is fixedly connected to the top of the processing bed 1 near the slide rail 4.

[0030] like Figure 3 As shown, an active stretching mechanism 6 is provided on the top of the mounting block 5, and the active stretching mechanism 6 includes a hydraulic cylinder 601 installed on the top of the mounting block 5, and the output end of the hydraulic cylinder 601 is fixedly connected to a connector 602, and the other end of the connector 602 is rotatably connected to a Y-shaped rotating rod 603, and one end of the Y-shaped rotating rod 603 is rotatably connected to a first transmission rod 604, and the other end of the first transmission rod 604 is rotatably connected to a first slider 605, and the inner wall of the first slider 605 slides in contact with the outer wall of the slide rail 4, and the first slider 605 can only move along the direction specified by the slide rail 4, and will not shake left and right or deviate from the track, and the top of the first slider 605 is fixedly connected to a first fixed block 606.

[0031] like Figure 3As shown, in the initial state, the hydraulic rod in the hydraulic cylinder 601 will be extended to the maximum state, and the hydraulic rod will push the Y-shaped rotating rod 603 to rotate around its installation point. During the rotation process, the Y-shaped rotating rod 603 and the first transmission rod 604 will be compressed, and the Y-shaped rotating rod 603 will push the first slider 605 to move through the first transmission rod 604. While the Y-shaped rotating rod 603 is rotating, the Y-shaped rotating rod 603 will also drive the passive tensile structure 7 to move synchronously through the connecting rod 9 connected to its bottom until the two mechanisms reach a relatively close position. The processing chain 8 is placed behind the first fixed block 606 and the passive tensile structure 7, and then the hydraulic cylinder 601 is started to control the hydraulic rod for recovery. During the retraction of the hydraulic rod, the hydraulic rod will pull back the Y-shaped rotating rod 603 to rotate around its installation point, and the Y-shaped rotating rod 603 will pull back the first transmission rod 604 and the first slider 605, and the connecting rod 9 at the bottom of the Y-shaped rotating rod 603 will also drive the passive tensile structure 7 to perform a synchronous pulling back movement. During the continuous pulling back process, the processing chain 8 installed on the two mechanisms is straightened and locked, which is convenient for subsequent processing.

[0032] like Figure 2 and Figure 4As shown, a passive tensile structure 7 is provided at the other side of the top of the slide rail 4. The passive tensile structure 7 includes a second slider 701 that slides on the outer wall of the slide rail 4. The top of the second slider 701 is fixedly connected to a second fixed block 702. The processing chain 8 is installed between the first fixed block 606 and the second fixed block 702. Installing the processing chain 8 between the first fixed block 606 and the second fixed block 702 can provide stable support and guidance for the chain. The fixed block can limit the lateral movement of the chain so that it always runs along a predetermined path, avoiding the processing chain 8 from deviating, swinging or derailing. One side of the second slider 701 is rotatably connected to a second transmission rod 703, and the other end of the second transmission rod 703 is rotatably connected to a V-shaped rotating rod 704. The V-shaped rotating rod 704 is rotatably connected to the inside of the slide rail 4. This connection method allows the V-shaped rotating rod 704 to rotate flexibly in the slide rail 4 and makes full use of the space, making the structure of the entire adjusting device more compact. The processing chain 8 is installed on the top of the passive tensile structure 7. The bottom is rotatably connected with a connecting rod 9, which is installed between the Y-shaped rotating rod 603 and the V-shaped rotating rod 704. The connecting rod 9 plays a key connecting role between the Y-shaped rotating rod 603 and the V-shaped rotating rod 704, and can effectively transmit power and motion. When the Y-shaped rotating rod 603 rotates or moves, this motion can be transmitted to the V-shaped rotating rod 704 through the connecting rod 9, thereby realizing the coordinated operation of the entire chain tension adjustment device. When the active stretching mechanism 6 is moving, the Y-shaped rotating rod 603 inside the active stretching mechanism 6 will drive the V-shaped rotating rod 704 to move synchronously through the connecting rod 9. Because one end of the V-shaped rotating rod 704 is connected to the connecting rod 9 and the other end is connected to the second transmission rod 703, when the V-shaped rotating rod 704 is stretched by the connecting rod 9 and rotates, it will also drive the second transmission rod 703 to move synchronously. Finally, the second transmission rod 703 realizes the synchronous stretching movement of the second slider 701 and the second fixed block 702, and the processing chain 8 is straightened and locked.

[0033] When the present invention is in use, in the initial state, the hydraulic rod in the hydraulic cylinder 601 will be extended to the maximum state, and the hydraulic rod will push the Y-shaped rotating rod 603 to rotate around its installation point. During the rotation, the Y-shaped rotating rod 603 and the first transmission rod 604 will be compressed, and the Y-shaped rotating rod 603 will push the first slider 605 to move through the first transmission rod 604 to reach the middle position of the slide rail 4. While the Y-shaped rotating rod 603 is rotating, it will also drive the V-shaped rotating rod 704 to move synchronously through the connecting rod 9. Because one end of the V-shaped rotating rod 704 is connected to the connecting rod 9 and the other end is connected to the second transmission rod 703, When the connecting rod 9 is stretched and rotated, it will also drive the second transmission rod 703 to move synchronously, and finally the second transmission rod 703 will push the second slider 701 and the second fixed block 702, so that the second slider 701 and the second fixed block 702 will also reach the middle position of the slide rail 4. When the processing chain 8 to be processed is placed on the top of the first slider 605 and the second slider 701, the hydraulic cylinder 601 is used to control the hydraulic rod to be recovered, and the first slider 605 and the second slider 701 are pulled back by the reverse movement of the above steps. In the continuous pulling back process, the processing chain 8 installed on the two mechanisms is straightened and locked, which is convenient for subsequent processing.
