Description

Technical Field

[0001] This utility model relates to the field of inclined wedge technology, specifically to a lifting hook and punch inclined wedge return limit device. Background Technology

[0002] A wedge mechanism is a mechanical mechanism that transforms vertical motion into horizontal or inclined motion through the cooperation of a wedge and a slider, converting the vertical force of a machine tool into an inclined force. A lifting wedge is a stamping process where the actuator is in the lower die, while the slider and guide device are in the upper die. A lifting hook-punch wedge is an application of the wedge mechanism, specifically used for punching holes on the inclined surfaces of parts. To ensure the wedge stops accurately at a predetermined position during its return stroke, a return limit device is typically used to limit the return stroke of the lifting hook-punch wedge. The return limit device restricts the return movement of the lifting wedge. In a wedge mechanism, the return limit device ensures that the lifting hook-punch wedge can safely and accurately return to its original position after punching or other processes, thereby preventing equipment damage and ensuring the normal operation of subsequent processes.

[0003] When using a hoisting hook-and-punch wedge, although the return limit device can limit the return of the wedge, it is prone to wear and tear during long-term use. In the existing technology, the return limit device is usually installed on the base with bolts, which makes it inconvenient to quickly maintain or replace it when it is worn out. As a result, the device cannot guarantee the limiting effect of the wedge. Therefore, in order to solve the above problems, a hoisting hook-and-punch wedge return limit device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting hook and wedge return limit device to solve the problem mentioned in the background art that the device is prone to wear and tear during long-term use. In the prior art, the return limit device is usually installed on the base with the help of bolts, which makes it inconvenient to quickly maintain or replace the return limit device when it is worn out, thus failing to ensure the device's limiting effect on the wedge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting hook and wedge return limit device, comprising a base, a sliding block movably connected to the surface of the base, a driving block fixedly connected to the surface of the sliding block, a limit block provided on the surface of the base, and the sliding block and the limit block movably connected.

[0006] The surface of the limiting block is provided with a replacement mechanism, the replacement mechanism includes a connecting block, the connecting block is fixedly connected to the inner surface of the limiting block, the inner side of the base is provided with an installation groove, the inner side of the limiting block is provided with a movable groove, the inner side of the movable groove is movably connected with a plug rod, the inner wall of the installation groove is provided with a slot, and the surface of the plug rod is fixedly connected with a first spring.

[0007] Preferably, the connecting blocks are arranged in two sets and correspondingly connected to the limiting blocks, and the mounting grooves are arranged in two sets on the inner side of the base.

[0008] Preferably, the movable slots are arranged in two groups on the inner side of the limiting block and the connecting block, the insert rods are arranged in four groups and connected to the movable slots, and the slots are arranged in two groups on the inner wall of the mounting slot.

[0009] Preferably, one end of the first spring is fixedly connected to the movable groove, and the other end of the first spring is fixedly connected to the insertion rod.

[0010] Preferably, the surface of the base is provided with an auxiliary mechanism, the auxiliary mechanism including a fixed rod, the fixed rod being fixedly connected to the inner surface of the base, a second spring being fixedly connected to the inner wall of the fixed rod, a movable rod being fixedly connected to the end of the second spring away from the fixed rod, and a third spring being fixedly connected to the inner surface of the base.

[0011] Preferably, the movable rod is movable inside the fixed rod, the end of the movable rod away from the second spring is fixedly connected to the sliding block, one end of the third spring is fixedly connected to the base, and the other end of the third spring is fixedly connected to the sliding block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By moving the insertion rod within the movable slot, in conjunction with the elasticity of the first spring, the insertion rod can engage and disengage with the slot during movement. This enables rapid fixing and disassembly of the limit block and the base. When the limit block is worn during use, it is easy to quickly disassemble and reassemble, facilitating maintenance or replacement. This ensures the limiting effect of the limit block on the sliding block and the drive block. Simultaneously, through the cooperation of the connecting block and the mounting slot, the installation of the limit block on the base can be positioned, making the installation of the limit block more convenient and accurate.

[0014] 2. Through the combined action of the second and third springs, the sliding block can be reset, facilitating the return motion of the sliding block and the drive block. This allows the drive block to be positioned at a predetermined location. Simultaneously, the fixed rod and the movable rod ensure that the movable rod can move within the fixed rod when the sliding block moves, thereby limiting the movement of the third spring. This helps ensure the stability of the third spring, preventing deformation and skewness, thus guaranteeing its usability and ensuring the return motion effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] A lifting hook and wedge return limit device includes a base 1, a sliding block 11 movably connected to the surface of the base 1, a driving block 12 fixedly connected to the surface of the sliding block 11, and a limit block 13 provided on the surface of the base 1. The sliding block 11 and the limit block 13 are movably connected. By setting the limit block 13, the sliding block 11 can move on the surface of the limit block 13 when it moves, thereby limiting the sliding block 11 by the limit block 13 and ensuring the stability of the movement and return of the sliding block 11 and the driving block 12.

[0023] The surface of the limiting block 13 is provided with a replacement mechanism, which includes a connecting block 2. The connecting block 2 is fixedly connected to the inner surface of the limiting block 13. The inner side of the base 1 is provided with an installation groove 21, and the inner side of the limiting block 13 is provided with a movable groove 22. The inner side of the movable groove 22 is movably connected with a plug rod 23. The inner wall of the installation groove 21 is provided with a slot 24. The surface of the plug rod 23 is fixedly connected with a first spring 25. Through the movement of the plug rod 23, in conjunction with the elasticity of the first spring 25, the plug rod 23 and the slot 24 can be easily inserted and separated, thereby facilitating the installation or removal and replacement of the limiting block 13, and ensuring the limiting effect of the limiting block 13 on the sliding block 11.

[0024] Furthermore, the connecting blocks 2 are connected in two sets to the corresponding limiting blocks 13, and the mounting slots 21 are opened in two sets on the inner side of the base 1. Through the setting of the connecting blocks 2 and the mounting slots 21, the limiting blocks 13 can be fixed and positioned on the base 1, which makes it easier to accurately install the limiting blocks 13 in the corresponding position, making the installation of the limiting blocks 13 more convenient.

[0025] Furthermore, two sets of movable slots 22 are provided on the inner side of the limiting block 13 and the connecting block 2, four sets of insert rods 23 are connected to the movable slots 22, and two sets of slots 24 are provided on the inner wall of the mounting slot 21. By providing slots 24, when the insert rods 23 are engaged and disengaged from the slots 24, the limiting block 13 and the base 1 can be fixed and disassembled, thereby facilitating the maintenance or replacement of the limiting block 13 as a whole.

[0026] Furthermore, one end of the first spring 25 is fixedly connected to the movable groove 22, and the other end of the first spring 25 is fixedly connected to the insertion rod 23. By setting the first spring 25, the insertion rod 23 can be reset, thereby enabling the insertion rod 23 and the slot 24 to be inserted, which facilitates the installation of the limiting block 13 on the base 1.

[0027] Furthermore, an auxiliary mechanism is provided on the surface of the base 1. The auxiliary mechanism includes a fixed rod 3, which is fixedly connected to the inner surface of the base 1. A second spring 31 is fixedly connected to the inner wall of the fixed rod 3. A movable rod 32 is fixedly connected to the end of the second spring 31 away from the fixed rod 3. A third spring 33 is fixedly connected to the inner surface of the base 1. By moving the movable rod 32 within the fixed rod 3, the setting of the third spring 33 can be limited, making the third spring 33 more stable during use and preventing deformation of the third spring 33, thereby better supporting the return stroke of the drive block 12.

[0028] Furthermore, the movable rod 32 is movable inside the fixed rod 3. The end of the movable rod 32 away from the second spring 31 is fixedly connected to the sliding block 11. One end of the third spring 33 is fixedly connected to the base 1, and the other end of the third spring 33 is fixedly connected to the sliding block 11. By connecting the base 1 and the sliding block 11 through the third spring 33, the sliding block 11 can be reset, which facilitates the return movement of the sliding block 11 and the drive block 12, ensuring that the drive block 12 can stay in the predetermined position.

[0029] Working principle: In use, by pulling the insertion rod 23, the insertion rod 23 can move inside the movable slot 22, which can separate the insertion rod 23 from the slot 24, thereby releasing the fixation of the limiting block 13 and the base 1. At this time, the first spring 25 is in a contracted state, and the limiting block 13 can be removed for maintenance or replacement. When it is necessary to install the limiting block 13, the connecting block 2 is inserted into the mounting slot 21, and the insertion rod 23 is released. The insertion rod 23 will return to its original position under the rebound action of the first spring 25, thereby realizing the insertion of the insertion rod 23 and the slot 24, thus realizing the installation of the limiting block 13.

[0030] When the sliding block 11 moves, the second spring 31 and the third spring 33 deform. Through the elastic properties of the second spring 31 and the third spring 33, the sliding block 11 can be reset, thus achieving the return stroke. At the same time, the movement of the sliding block 11 causes the movable rod 32 to move within the fixed rod 3. The cooperation between the fixed rod 3 and the movable rod 32 can effectively prevent the third spring 33 from deforming or tilting, thereby ensuring the effectiveness of the third spring 33.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
