Abstract
Description
Technical Field
[0001] This utility model relates to the field of gearbox processing technology, and in particular to a positioning drilling device for gearbox processing. Background Technology
[0002] Currently, drilling operations on gearbox housings mostly rely on general-purpose or special-purpose drilling machines. The typical processing flow is for the operator to fix one side of the housing on the machine tool workbench, use a fixture for initial positioning, and then use a drill bit to complete the hole machining on that side of the housing.
[0003] However, some traditional drilling equipment still has shortcomings: Since most of the mounting holes on the gearbox are diagonally or symmetrically arranged, traditional devices cannot effectively drill diagonal holes, resulting in poor diagonal positioning accuracy and difficulty in ensuring coaxiality. Especially for mass production, the ability to drill holes simultaneously at two diagonal or symmetrical positions of the gearbox is very important. This not only limits processing efficiency but also affects processing accuracy. Therefore, improvements are urgently needed. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning drilling device for gearbox machining.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A positioning drilling device for gearbox processing includes a machine body, a drive compartment is configured on one side of the machine body, a ring frame is mounted on the bottom of the drive compartment via a support shaft, a plurality of pneumatic drilling heads are mounted on the ring frame via mounting brackets, and two symmetrical mounting brackets are connected as a whole by a pair of crossbars. The two ends of the crossbar are fitted with snap-fit connectors, which are connected to the crossbar by springs. The snap-fit connectors are snapped into the limiting grooves opened on the side wall of the mounting frame. The upper part of the mounting bracket is screwed with a locking bolt. The bottom of the locking bolt is a smooth section that passes through the mounting bracket and engages with the limiting hole in the middle of the limiting convex rail on the upper part of the ring frame.
[0006] In addition, a preferred structure is that a clamping platform is provided at the lower part of the machine body, and a pneumatic drill head is provided above the clamping platform.
[0007] Furthermore, a preferred configuration is one in which a gap is left between adjacent crossbars and the crossbars pass through the outside of the support shaft.
[0008] Furthermore, in a preferred configuration, a ring frame is fixedly mounted at the bottom of the support shaft.
[0009] Furthermore, a preferred structure is that the mounting bracket has a slot in the middle to fit the ring frame.
[0010] In addition, a preferred structure is that the upper part of the ring frame is provided with a limiting convex rail, the cross section of the limiting convex rail is rectangular, and the upper wall of the limiting convex rail is provided with a groove, and multiple limiting holes are provided in the groove in an equal angle array, the limiting holes and the locking bolts are mutually engaging mechanisms.
[0011] In addition, a preferred structure is that multiple limiting grooves are symmetrically provided on one side of the mounting bracket.
[0012] The beneficial effects of this utility model are as follows: In this invention, the mounting bracket is fixed and released by tightening or loosening the locking bolts, and the two mounting brackets are adjusted diagonally synchronously by using a crossbar. Alternatively, the individual mounting bracket can be positioned independently by removing the crossbar. This allows for flexible adaptation to the diagonal positioning drilling requirements at different positions on the gearbox, thereby improving positioning and processing efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figure 1-4 A positioning drilling device for gearbox processing includes a body 1, a drive compartment 2 is arranged on one side of the body 1, a ring frame 4 is installed at the bottom of the drive compartment 2 via a support shaft 8, a plurality of pneumatic drilling heads 5 are installed on the ring frame 4 via mounting brackets 6, and two symmetrical mounting brackets 6 are connected as a whole by a pair of crossbars 7. The drive compartment 2 is used to drive the support shaft 8 downward to achieve the drilling function. The specific drive mechanism is a conventional configuration in drilling equipment and belongs to a common drive method in this field, so it will not be explained further.
[0017] The pneumatic drill bit 5 differs from the electric drill bit in that it uses compressed gas to drive drilling operations. The pneumatic drill bit 5 is connected to an external pneumatic feed system, and the specific connection method and driving principle are common knowledge to those skilled in the art.
[0018] The two ends of the crossbar 7 are fitted with snap-fit connectors 72. The snap-fit connectors 72 are connected to the crossbar 7 by springs 71. The snap-fit connectors 72 are snapped into the limiting grooves 62 opened on the side wall of the mounting bracket 6. The upper part of the mounting bracket 6 is screwed with a locking bolt 61. The bottom of the locking bolt 61 is a smooth section that passes through the mounting bracket 6 and engages with the limiting hole 42 opened in the middle of the limiting cam 41 on the upper part of the ring frame 4.
[0019] The lower part of the body 1 is provided with a fixture platform 3, and a pneumatic drill head 5 is provided above the fixture platform 3. The fixture platform 3 is used to install fixtures. The specific installation method and fixture model are existing technologies and will not be explained further.
[0020] A gap is left between adjacent crossbars 7 and they pass through the outside of the support shaft 8, so that the support shaft 8 will not be affected during the rotation of the crossbars 7.
[0021] A ring frame 4 is fixedly installed at the bottom of the support shaft 8.
[0022] The mounting bracket 6 has a slot in the middle to fit the annular frame 4, and the mounting bracket 6 can slide along the annular frame 4.
[0023] The upper part of the ring frame 4 is provided with a limiting convex rail 41. The limiting convex rail 41 has a rectangular cross section and a groove is provided on the upper wall of the limiting convex rail 41. Multiple limiting holes 42 are provided in the groove in an equal angle array. The limiting holes 42 and the locking bolt 61 are mutually engaging mechanisms.
[0024] Multiple limiting grooves 62 are symmetrically provided on one side of the mounting bracket 6.
[0025] In this embodiment, the locking bolts 61 on the two mounting brackets 6 are loosened so that they are disengaged from the limiting holes 42 on the upper part of the ring frame 4. At this time, the mounting brackets 6 can move freely on the ring frame. By rotating any mounting bracket 6 to move on the ring frame 4, the other mounting bracket 6 can be moved synchronously through the crossbar 7, so as to realize the linkage adjustment of the drilling position and the diagonal relationship.
[0026] When individual adjustments are required, the crossbar 7 can be pulled inward to disengage the locking connector 72 at its end from the limiting groove 62 on the outside of the mounting bracket 6, thereby releasing the connection between the two mounting brackets. At this time, each mounting bracket 6 can move independently to meet the opening requirements of asymmetrical positions.
[0027] The mounting bracket 6 is fixed and released by tightening or loosening the locking bolt 61. This supports both synchronous diagonal adjustment of the two mounting brackets and independent positioning of a single mounting bracket, and can flexibly adapt to the diagonal drilling requirements at different positions on the gearbox.
[0028] In practical application, the gearbox workpiece is fixed on the fixture table 3 of the machine body 1 by the fixture, and the ring frame 4, i.e. the pneumatic drill head 5, is driven by the drive chamber 2 to move down to the drilling position of the gearbox workpiece. At this time, the external air source feed system drives the pneumatic drill head 5 to run to realize the drilling operation. The more specific working principle and process are common knowledge to those skilled in the art and will not be explained further.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
