Description

Technical Field

[0001] The utility model relates to the technical field of turbine jigs, in particular to a new type of rotary box turbine jig. Background Technique

[0002] The power of the rotary box is input by a motor to drive the turbine shaft to rotate. The meshed turbine rotates to achieve primary deceleration. At the same time, through frictional transmission, the upper friction cone rotates and drives the output shaft to rotate through its own key block to achieve secondary deceleration. Thus, it can be seen that the turbine plays a crucial role in the working process of the rotary reduction box. When the turbine is damaged, it needs to be repaired immediately. Due to the shape of the turbine, it is very difficult to fix it during the repair and processing. At worst, the tooth surface of the turbine will be damaged during the clamping process (because the material of the turbine is brass and its texture is relatively soft). At worst, the turbine will loosen during the processing, resulting in turbine damage. Moreover, when clamping the turbine, the fixture needs to be installed. The existing fixtures are all installed and fixed by pins or bolts. However, when fixing with bolts, if there are multiple groups of bolts to be rotated and fixed, how to ensure that the installation and fixing positions of the bolts are the same to prevent slight differences in the fixing positions of multiple groups of bolts from causing insufficient clamping and resulting in deviation of the processing results.

[0022] In this embodiment, specifically referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the rotating assembly 9 includes a fixed pin 901 and a sliding ball block 902.

Multiple groups of limiting cushion blocks 904 are arranged and are respectively located on the outer wall of the fixed pin 901. The limiting cushion block 904 is located on the outer wall of the fastening pressing plate 6. The other end of the fixed pin 901 is rotatably connected to a rotating block 905. A positioning gear 906 is installed on the outer wall of the rotating block 905. Multiple groups of positioning gears 906 are arranged and are respectively located on the outer wall of the rotating block 905. Multiple groups of rotating blocks 905 are arranged and are respectively located on the outer wall of the fixed pin 901. The limiting cushion block 904 and the rotating block 905 are respectively located on the opposite side walls of the fastening pressing plate 6. A limiting sleeve 907 is installed on the outer wall of the fixed pin 901 on one side of the positioning gear 906. A fastening thread groove 908 is opened on the inner wall of the limiting sleeve 907. The connection mode between the fastening thread groove 908 and the fixed threaded rod 3 is threaded connection. A limiting ring 909 is installed at one end of the limiting sleeve 907. The limiting ring 909 is located on the outer wall of the fixed threaded rod 3 and the connection mode is sliding connection. The sliding ball block 902 is slidably connected to the inner wall of the sliding groove 8. Multiple groups of sliding ball blocks 902 are arranged and are respectively located on the inner wall of the sliding groove 8.

Two groups of handles 913 are arranged and are respectively located on the outer wall of the fixed ring 911.

[0023] Among them, multiple groups of fixing holes 2 are provided and are respectively located on the outer wall of the clamping pressing plate 1. Multiple groups of fixing threaded rods 3 are provided and are respectively located on the inner wall of the fixing holes 2. The fastening pressing plate 6 is located directly below the clamping pressing plate 1. Multiple groups of fixing holes 2 are provided and are respectively located on the outer wall of the fastening pressing plate 6. The fixing ring 911 is located on one side of the fastening pressing plate 6. The clamping pressing plate 1 is a chamfered boss structure, so as to facilitate the fixation of the turbine body 5. The turbine body 5 is stable and has no abnormal movement during the process of being machined on the lathe after being clamped by the fixture, so that the turbine body 5 can be quickly and accurately machined to the required size, and the repair process can be completed better and faster, and then the rotating box is restored.

[0024] When the novel rotating box turbine fixture of this solution works, fixing holes 2 are provided on the outer wall of the clamping pressing plate 1, and fixing threaded rods 3 are inserted and connected on the inner wall of the fixing holes 2. Under the action of the fixing grooves 4 provided on the inner wall of the clamping pressing plate 1, the turbine body 5 is placed on the inner wall of the fixing grooves 4 for preliminary fixation. Under the action of the chamfered boss structure of the clamping pressing plate 1, it plays a role in radial positioning and prevents the turbine from moving during the machining process. Under the action of the threaded connection between the fastening thread groove 908 and the fixing threaded rod 3, the fixing threaded rod 3 is further fixed on the inner wall of the limiting sleeve 907 through the fastening thread groove 908 for fixation, so that the turbine body 5 is fixed between the fastening pressing plate 6 and the clamping pressing plate 1, and the fixing threaded rod 3 bolts and fixes it. After the turbine body 5 is fixed with the fixture, one end of the clamping pressing plate 1 is clamped on the lathe and then the turbine body 5 is machined, thus solving the problem that it is very difficult to fix the turbine during the repair and machining process due to its shape. In the light case, the tooth surface of the turbine is damaged during the clamping process (since the material of the turbine is brass and the texture is relatively soft), and in the serious case, the turbine loosens during the machining process, resulting in turbine damage.

[0025] A positioning gear 906 is installed on the outer wall of the rotating block 905. A limiting sleeve 907 is installed on one side of the fixed pin 901 and on the outer wall of the positioning gear 906. A fastening thread groove 908 is formed on the inner wall of the limiting sleeve 907. With a limiting ring 909 installed at one end of the limiting sleeve 907, it only needs to sleeved the limiting ring 909 on the outer wall of the fixed threaded rod 3, so that the fixed threaded rod 3 is connected to the fastening thread groove 908 on the inner wall of the limiting sleeve 907. At the same time, the sliding ball block 902 is slidably connected to the inner wall of the sliding groove 8. A connecting rod 910 is installed on the outer wall of the sliding ball block 902. One end of the connecting rod 910 is connected to a fixed ring 911. A tooth groove 912 is formed on the inner wall of the fixed ring 911. Under the action that one end of the tooth groove 912 is meshed with the positioning gear 906, it only needs to hold the handle 913 and rotate it, so that the handle 913 drives the fixed ring 911 to rotate, so that the fixed ring 911 drives the sliding ball block 902 to slide on the inner wall of the sliding groove 8 through the connecting rod 910. At the same time, the fixed ring 911 drives the positioning gear 906 to rotate through the tooth groove 912, so that the positioning gear 906 drives the rotating block 905 to rotate on the outer wall of the fixed pin 901. At the same time, the positioning gear 906 drives the limiting sleeve 907 to rotate, so that the fastening thread groove 908 on the inner wall of the limiting sleeve 907 is threadedly connected to the fixed threaded rod 3, so that the fixed threaded rod 3 moves to one side on the inner wall of the limiting sleeve 907, so that the fixed threaded rod 3 drives the clamping pressing plate 1 to move to one side, so that the clamping pressing plate 1 clamps the turbine body 5. Since the tooth groove 912 drives multiple groups of positioning gears 906 to rotate at the same time, the number of rotations of each group of positioning gears 906 is the same and the moving positions are also the same, so that multiple groups of fixed threaded rods 3 move at the same time, making the fixing effect of the device better. Thus, it solves the problem that when clamping a turbine, it is necessary to install a fixture. Existing fixtures are all installed and fixed by pins or bolts. However, when fixing with bolts, if multiple bolts are rotated and fixed, how to ensure that the installation and fixing positions of the bolts are the same to prevent slight differences in the fixing positions of multiple bolts from resulting in insufficient clamping and deviation in the processing results.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
