Technical Field

[0001] The utility model relates to the technical field of pin installation pliers, in particular to an installation plier for a gear protection ring. Background Art

[0002] A gear protection sleeve is a device that is sleeved on a gear to prevent the teeth of the gear from colliding with each other and causing damage to the gear. During the installation process of the protection sleeve, the locking pin needs to be installed on the locking card plate first, and then the locking card plate is installed on the installation sleeve through the locking pin. Finally, the installation of the protection sleeve is locked through the locking card plate.

[0003] During the process of installing the locking pin onto the locking plate, generally, it is currently installed manually by hand. Since the head and tail of the locking pin are both larger than the diameter of the installation hole on the locking plate, the installation efficiency of the locking pin onto the locking card plate is low, which in turn affects the subsequent installation efficiency of the protection sleeve. Summary of the Utility Model

[0004] In view of the above problems, the present utility model is proposed to provide an installation plier for a gear protection ring that can overcome or at least partially solve the above problems, which can solve the problem of low installation efficiency of the existing protection sleeve pins and achieve the effect of improving the installation efficiency of the pins on the locking card plate.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0031] Figure 1 is a schematic structural diagram of an installation pliers for a gear protection ring, as Figure 1 shown, and with reference to Figures 2 to 5 , the embodiment of the present utility model provides an installation pliers for a gear protection ring. The installation pliers for the gear protection ring includes two plier rods 100, two plier heads 200, and two installation chucks 300. The two plier rods 100 are pivotally connected. Each plier rod 100 is fixedly connected to a plier head 200, so that the included angle between the two plier rods 100 and the included angle between the two plier heads 200 are positively correlated. An installation groove 310 is provided on the installation chuck 300. Each installation chuck 300 is connected to a plier head 200, and the two installation grooves 310 are coaxially arranged.

[0032] Specifically, the installation pliers are used to install the locking pin of the protection ring on the locking card plate. The two plier rods 100 are hinged by a hinge shaft 110. Further, the two plier heads 200 and the two plier rods 100 form a traditional clamp structure. When the angle between the two plier rods 100 increases as they separate from each other, the angle between the two plier heads 200 also becomes larger. Conversely, when the angle between the two plier rods 100 decreases, the angle between the two plier heads 200 also correspondingly decreases. Thus, a positive correlation is formed between the angle of the two plier rods 100 and the angle of the two plier heads 200. Further, the two installation grooves 310 can respectively hold the two ends of the locking pin. Further, one end of the locking pin is installed in one installation groove 310, and the two plier heads 200 approach each other so as to be able to press and install the locking pin into the installation hole of the locking card plate, thereby quickly achieving the effect of installing the pin and improving the installation efficiency of the gear package replacement.

[0033] Further, the provision of one installation groove 310 on each installation chuck 300 enables, when the installation of the locking pin is completed, the extruded end of the locking pin to pass through the locking card plate opening and enter into the other installation groove 310. That is to say, one installation groove 310 is used to fix one end of the locking pin, and the other installation groove 310 provides a retreat space for the other end of the locking pin to pass through the locking card plate, so that the other end of the locking pin can completely extend out of the locking card plate through its own elastic recovery.

[0034] During operation, first install one end of the locking pin into one installation groove 310, and then align the other end of the locking pin with the clamping hole of the locking card plate. Then apply a force to make the angle between the two plier rods 100 approach each other, so that the angle between the two plier rods 100 decreases, thereby driving the angle between the two plier heads 200 to decrease, and further causing the two installation chucks 300 to approach each other. The installation chuck 300 drives the locking pin to move towards the installation hole of the locking card plate. The locking pin is pressured and the other end passes through the installation hole of the locking card plate, thus completing the installation of the locking pin.

[0035] In some embodiments of the present utility model, such as Figures 3 to 5As shown, the mounting clamp of the gear protection ring also includes an adjustment clamp 400, which is installed on a mounting chuck 300. The adjustment clamp 400 includes an arc-shaped clamp plate 410, an adjustment rod 420 and an adjustment elastic member 430. The arc-shaped clamp plate 410 can be slidably arranged in the mounting groove 310 along the radial direction of the mounting groove 310, and the arc-shaped clamp plate 410 and the inner wall of the mounting groove 310 define a clamping claw; the adjustment rod 420 is inserted into the mounting chuck 300 along the radial direction of the mounting chuck 300, and one end is fixedly connected to the arc-shaped clamp plate 410. The adjustment elastic member 430 is installed on the adjustment rod 420, and the adjustment elastic member 430 is used to make the adjustment rod 420 located at the innermost end of the mounting chuck 300 in the initial state, so as to minimize the clamping claw.

[0036] Specifically, the mounting chuck 300 is columnar, and the mounting groove 310 is circular. Further, the axis of the arc-shaped clamping plate 410 is arranged parallel to the axis of the mounting groove 310, and the arc-shaped clamping plate 410 can be arranged to slide along the radial direction of the mounting groove 310, so that the size of the mounting clamping claw can be changed. Specifically, when the arc-shaped clamping plate 410 slides in the axial direction of the mounting groove 310, the clamping claw becomes smaller, so that the mounting chuck 300 can clamp the head of the locking pin with a smaller diameter. Conversely, the clamping claw becomes larger, so that the mounting chuck 300 can clamp the head of the pin with a larger diameter. In other words, the setting of the arc-shaped clamping plate 410 enables the mounting chuck 300 to install a variety of different types of locking pins, thereby increasing the scope of application of the mounting pliers.

[0037] Furthermore, the setting of the adjustment rod 420 can adjust the sliding distance of the arc-shaped clamping plate 410, thereby changing the size of the clamping claw. The setting of the adjustment rod 420 can reduce the difficulty of installing the locking pin into the mounting chuck 300. Furthermore, the initial state of the adjustment elastic member 430 is adjusted to make the clamping card turn to the minimum setting, that is, when the clamping claw needs to be enlarged, the adjustment rod 420 is pulled outward, and the arc-shaped clamping plate 410 is driven to a certain position, and the adjustment elastic member 430 is stretched and stored. When the head of the locking pin is installed in the mounting groove 310, the adjustment rod 420 is released, and the adjustment elastic member 430 drives the arc-shaped clamping plate 410 to reset, thereby clamping the head of the locking pin.

[0038] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the gear protection ring mounting pliers further include two connecting rods 500, which are arc-shaped rods. One end of each connecting rod 500 is connected to a clamp head 200, and the other end is fixedly connected to a mounting chuck 300. The two connecting rods 500 are symmetrically arranged, and the two arc-shaped openings are arranged opposite to each other. The other end of the connecting rod 500 is configured to maintain a preset distance between the two mounting chucks 300 when the angle between the two clamp heads 200 is the smallest.

[0039] Specifically, the setting of the connecting rod 500 can increase the distance between the mounting chuck 300 and the jaw 200, thereby increasing the operating distance of the mounting chuck 300 and enabling the installation of locking pins with relatively special mounting positions. Further, the connecting rod 500 is arranged in an arc-shaped rod shape, which can prevent other structures located between the two connecting rods 500 from preventing the angle between the two connecting rods 500 from decreasing when the two mounting chucks 300 approach each other. That is to say, a space is generated between the two connecting rods 500 to ensure the clamping force of the two mounting chucks 300 on the locking pin.

[0040] In some embodiments of the present invention, such as Figure 1 and Figure 2 shown, the two mounting chucks 300 are respectively a first chuck 320 and a second chuck 330. The inner diameter of the mounting groove 310 on the first chuck 320 is a first preset value; the inner diameter of the mounting groove 310 on the second chuck 330 is a second preset value. The first preset value is greater than the first preset value.

[0041] Specifically, since the diameters between the head and the tail of the locking pin are different, and the diameter of the head of the locking pin is greater than the diameter of its tail, the head of the locking pin is installed in the first chuck 320.

[0042] In some embodiments of the present invention, such as Figure 5 shown, the adjusting elastic member 430 includes an adjusting spring. The adjusting spring is sleeved on the adjusting pull rod 420. One end of the adjusting spring is fixedly connected to the adjusting pull rod 420, and the other end is fixedly connected to the mounting chuck 300. Specifically, one end of the adjusting spring is fixedly connected to the outer wall of the mounting chuck 300. When the adjusting pull rod 420 is pulled outwards, it drives the arc-shaped clamping plate to move synchronously, so that the adjusting spring stretches and stores energy.

[0043] In some embodiments of the present invention, such as Figure 1 shown, the installation pliers of the gear protection ring further include a return spring 600. The return spring 600 is arranged between the two plier rods 100, and the two ends are respectively connected to the two plier rods 100. The return spring 600 is used to contract and store energy when the angle between the two plier rods 100 decreases. Specifically, in the initial state, the two plier rods 100 are in an open state, so that the two mounting chucks 300 are in a fully open state. Further, when the angle between the two plier rods 100 becomes smaller, the angle between the two plier rods 100 becomes smaller, so that the return spring 600 stores energy. When the return spring 600 is released, it drives the two plier rods 100 to return to the initial state again. Further, the setting of the return spring 600 can prevent the two plier rods 100 from being manually reset, thereby increasing the convenience of operation.

[0044] At this point, those skilled in the art should recognize that although numerous exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and determined to cover all such other variations or modifications.
