Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figures 1 - 4 , a positioning device for processing a crusher gear ring, including a base 1, and a plurality of through holes 23 arranged at intervals are opened along the edge of the base 1, so that the base 1 can be fixedly installed by bolts, that is, bolts are used to pass through the through holes 23 to install the positioning device on the crusher gear ring processing equipment.

[0026] As Figure 1 and Figure 4 shown, a hollow support column 2 is vertically installed on the top of the base 1, a hollow connecting seat 3 is connected to the top of the support column 2, and at least three strip blocks 4 arranged at intervals are provided along the side surface of the connecting seat 3, and the strip blocks 4 are arranged along the radial direction of the support column 2. Among them, a plurality of reinforcement brackets 24 are provided on the side surface of the base 1, one end of the reinforcement bracket 24 is fixed on the side surface of the base 1, and the other end of the reinforcement bracket 24 is fixed to the end of the strip block 4 away from the connecting seat 3, providing an additional supporting effect for the strip block 4 and strengthening the fixing effect of the strip block 4 on the connecting seat 3.

[0027] A cavity 5 is correspondingly opened inside the strip block 4, the end of the cavity 5 penetrates through the connecting seat 3 and communicates with its interior, and a lead screw 7 is arranged in the cavity 5. One end of the lead screw 7 is rotatably installed on the end of the cavity 5, and the other end of the lead screw 7 is placed inside the connecting seat 3 and connected to a driving mechanism that drives its rotation, providing power for the rotation of the lead screw 7;

[0028] A strip-shaped groove 6 corresponding to and communicating with the cavity 5 is provided on the side surface of the strip-shaped block 4. A support seat 16 is arranged above the strip-shaped block 4. A cylindrical clamping block 17 is vertically installed at one end of the support seat 16. The bottom of the support seat 16 is arranged on the support frame 15. The support frame 15 is connected with a moving seat 13 through a connecting frame 14 penetrating through the strip-shaped groove 6. The moving seat 13 is threadedly installed on the lead screw 7. The edge of the crusher gear ring will fall on the support seat 16. As the support seat 16 moves under the rotation of the lead screw 7, the side surface of the crusher gear ring can be acted on to clamp and fix it. Since the support seat 16 is supported and fixed by the support frame 15, a gap is left between the support seat 16 and the strip-shaped block 4, that is, only the bottom edge position and the side of the crusher gear ring are in contact with this positioning device, so that the waste chips generated during the processing of the crusher gear ring fall along the surface of the crusher gear ring and will not accumulate on the surface of the crusher gear ring, effectively preventing the deposition of waste chips from affecting the subsequent processing.

[0029] Among them, as Figure 3 and Figure 4 shown, the driving mechanism includes a connecting shaft 8. The connecting shaft 8 is coaxially installed at the end of the lead screw 7. The other end of the connecting shaft 8 is rotatably installed on the side surface of the rotating seat 10. The rotating seat 10 is rotatably installed on the driving shaft 11. The end of the driving shaft 11 is fixed to the inner wall of the connecting seat 3. The bottom of the driving shaft 11 penetrates through the bottom of the connecting seat 3 and is connected with a driving motor 18. The driving motor 18 is fixed in the support column 2. A second bevel gear 12 is coaxially installed on the driving shaft 11. A plurality of first bevel gears 9 are meshed on the side surface of the second bevel gear 12. The first bevel gears 9 are coaxially installed on the connecting shaft 8, so that the operation of one driving motor 18 can control the rotation of all the lead screws 7. In the actual use process, the specifications of all the lead screws 7 are the same. When the driving motor 18 operates, the support seats 16 all move above the strip-shaped block 4 at the same rate, so as to cooperate with the annular structure of the crusher gear ring, so that when the crusher gear ring is clamped and fixed, it can be centered and positioned with the axis of the support column 2 as the axis, providing convenience for subsequent processing.

[0030] Specifically, the support base 16 is rotatably installed on the top of the support frame 15. If the teeth of the crusher gear ring are located on the outer wall, the support base 16 can be first moved to a position corresponding to the inner diameter of the crusher gear ring, and then the support base 16 is rotated so that the clamping block 17 is located inside the crusher gear ring after the crusher gear ring is placed on the support base 16. Finally, only by controlling the support base 16 to move away from the connecting seat 3 can the crusher gear ring be propped up and fixed from the inside; if the teeth of the crusher gear ring are located on the inner wall, the support base 16 can be first moved to a position corresponding to the outer diameter of the crusher gear ring, and then the support base 16 is rotated so that the clamping block 17 is located outside the crusher gear ring after the crusher gear ring is placed on the support base 16. Finally, controlling the support base 16 to approach the connecting seat 3 can squeeze and fix the crusher gear ring; in summary, after the crusher gear ring is fixed according to the tooth position, the processing operation of the crusher gear ring can be carried out. The waste chips generated by the processing can also directly fall along the surface of the crusher gear ring due to the propping up and fixing of the crusher gear ring, without affecting the processing process.

[0031] Further, a slide rail 19 is provided on the side surface of the strip-shaped block 4. The slide rail 19 is arranged along the axis direction of the lead screw 7, and a slider 20 is slidably installed on the slide rail 19. The slider 20 is fixed to the support frame 15, guiding the movement of the support base 16 and also strengthening the support effect of the support frame 15 on the support base 16.

[0032] In order to provide the clamping effect after the clamping block 17 contacts the crusher gear ring, an anti-slip rubber sleeve is installed on the surface of the clamping block 17.

[0033] It should be noted that the strip-shaped groove 6 is provided on the bottom of the strip-shaped block 4, and the support frame 15 is an annular frame wound around the outside of the strip-shaped block 4, and the support frame 15 is in clearance fit with the strip-shaped block 4, which can prevent the waste chips generated by the processing from falling into the cavity 5 and adhering to the lead screw 7, thereby affecting the operation of the moving seat 13 on the lead screw 7.

[0034] It should be further noted that, in order to facilitate the maintenance of the drive motor 18, an opening 21 is provided on one side of the support column 2, and a sealing door 22 is hinged on one side of the opening 21. The other side of the sealing door 22 is fixed to the support column 2 through a lock, so as to open the support column 2 for maintaining the drive motor 18.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
