Description

Technical Field

[0001] The invention belongs to the technical field of drilling equipment, and in particular relates to a device for repairing inner holes of cones. Background Art

[0002] The roller drill bit is a tool for breaking rocks in the earth's crust. It is widely used in oil, gas drilling and other mineral resource drilling and development. The three-cone drill bit is widely used in oil, gas, salt and other mineral resource drilling and non-excavation projects. The roller drill bit is mainly composed of the roller and the palm. At present, after the roller is forged, due to the mold, a little tailing will remain at the position of the roller hole. This tailing needs to be removed in the subsequent turning process. Some tailings are relatively large and require a long time of turning to remove, which is a waste of time. If it is cut short with hydraulic shears, the roller needs to be fixed, and the workers also need to use a lot of force to operate the hydraulic shears, which is more physically demanding. Summary of the invention

[0003] The purpose of the present invention is to provide a device for repairing the inner hole of a gear to solve the construction and quality problems existing in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for repairing the inner hole of a gear, comprising a bottom plate, a base, a support column, a top plate, a clamping cylinder, a pressing film and a pneumatic scissors, wherein the base is fixed to the bottom plate, and the base is provided with a boss for placing the gear, one side of the boss is open, and the blade of the pneumatic scissors is located at the opening, the pneumatic scissors are mounted on the bottom plate through a bracket, the top plate is connected to the bottom plate through the support column, the clamping cylinder is fixed to the top plate, the piston rod of the clamping cylinder is connected to the connecting plate, the bottom of the connecting plate is fixed with the pressing film, and the internal shape of the pressing film matches the surface of the gear.

[0005] Preferably, four guide sleeves are fixed on the top plate, a guide column is slidably connected in each guide sleeve, and the lower end of the guide column is connected to the connecting plate.

[0006] Preferably, a position sensor is provided on the connecting plate.

[0007] Preferably, a collection box is provided in the base.

[0008] Preferably, a through hole for placing a gear is provided in the middle of the boss.

[0009] The beneficial effect of the present invention is that compared with the prior art, the device can quickly remove the tailings at the edge of the gear hole by positioning the gear and then using pneumatic shears to clean the tailings at the edge, thereby greatly improving the work efficiency.

[0013] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0014] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0015] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fixed connection" and "fixed connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0016] The specific implementation of the present invention is described in detail below with reference to the preferred embodiments of the accompanying drawings.

[0017] like Figure 1-3As shown, a device for repairing the inner hole of a gear comprises a bottom plate 1, a base 2, a support column 3, a top plate 4, a pressing cylinder 5, a pressing film 6 and a pneumatic scissors 7. The base is fixed on the bottom plate. A boss 8 for placing the gear is provided on the base. One side of the boss is opened 17. A through hole 15 for placing the gear is provided in the middle of the boss. The opening is connected to the through hole. The blade of the pneumatic scissors is located at the opening. The pneumatic scissors are mounted on the bottom plate through a bracket 16. The angle of the pneumatic scissors can be adjusted through the bracket so that the blade of the scissors is just located at the tailings position to be removed from the inner hole of the gear. When in use, the forged gear is buckled on the boss. Since the positions of all tailings in the inner hole of the gear are the same, it is only necessary to fix the gear in a fixed position and mark the boss. The gear is adjusted to a fixed angle each time and placed at the position marked on the boss. At this time, the tailings are just opposite to the blade position of the pneumatic scissors. In the initial state, the blade of the pneumatic scissors is in an open state.

[0018] The top plate is connected to the bottom plate through the support column, the pressing cylinder is fixed on the top plate, the piston rod of the pressing cylinder is connected to the connecting plate 9, the bottom of the connecting plate is fixed with the pressing film, and the internal shape of the pressing film matches the surface of the cone 10. The pressing film is driven downward by the pressing cylinder, and the pressing film presses the upper part of the cone to prevent the cone from moving during the working process. Finally, the pneumatic shears can cut off the excess tailings in the inner hole of the cone.

[0019] In order to make the pressing film move up and down more smoothly, four guide sleeves 11 are fixed on the top plate, and a guide column 12 is slidably connected in each guide sleeve, and the lower end of the guide column is connected to the connecting plate.

[0020] In order to determine the film pressing position and prevent the gear from being damaged by excessive pressure, a position sensor 13 is provided on the connecting plate.

[0021] In order to collect the tailings, a collection box 14 is provided in the base.

[0022] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
