Description

Technical Field

[0001] This invention relates to the field of fixture technology, and specifically to a turning fixture for an automotive reducer flange. Background Technology

[0002] The speed reducer is one of the most important components in the automotive steering control system. Its stability and safety play a crucial role in vehicle operation. The speed reducer needs to be connected via a flange. The flange has a simple structure but requires high precision, so the machining process is complicated and requires multiple steps. These steps include machining bolt holes on the flange periphery to facilitate the connection. During machining, a fixture is needed to fix the flange for drilling.

[0003] In existing technologies, flanges are often fixed using the outer circle fixing method, which involves fixing the outer ring of the flange to achieve its positioning, such as using jaws to clamp the outer circle of the flange. However, this method affects and hinders the machining of the outer circle, preventing the cutting tools from operating freely. Furthermore, the machining process generates a large amount of dust, which floats onto the flange surface. After machining, the flange needs to be manually or automatically cleaned, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a machining fixture for automotive reducer flanges, solving the following technical problems:

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-2 As shown, the present invention is a turning fixture for an automotive reducer flange, including a positioning seat 100. The positioning seat 100 is frustum-shaped and has a hollow interior. The bottom of the positioning seat 100 can be mounted on a machine tool. The circular area of ​​the upper surface of the positioning seat 100 is slightly larger than the area of ​​the central circular hole of the flange 400, so that the center of the flange 400 can be placed on the upper surface of the positioning seat 100.

[0030] A clamping mechanism 200 is installed at the center of the upper surface of the positioning seat 100. The clamping mechanism 200 includes a rotating shaft 201, which is movably inserted through a bearing seat into the upper wall of the positioning seat 100. The upper end of the rotating shaft 201 stands upright above the center of the positioning seat 100, and the lower end extends into the interior of the positioning seat 100. A driving mechanism 202 is also installed inside the positioning seat 100. The driving mechanism 202 is connected to the lower end of the rotating shaft 201 and is used to drive the rotating shaft 201 to rotate. The specific structure of the driving mechanism 202 is not limited, as long as it meets the requirement of driving the rotating shaft 201 to rotate. For example, in this embodiment of the invention, the driving mechanism 202 is a motor. The motor is installed on the bottom surface inside the positioning seat 100 through a motor frame, and the output end of the motor is connected to the lower end of the rotating shaft 201. When the motor is started, it can drive the rotating shaft 201 to rotate.

[0031] The rotating shaft 201 has an external thread on its shaft wall above the positioning seat 100. A hinge seat 203 is fitted onto the shaft wall of the rotating shaft 201 where the external thread is located. The inner ring of the hinge seat 203 has an internal thread that matches the external thread on the rotating shaft 201, meaning that the hinge seat 203 is threadedly connected to the rotating shaft 201. Multiple movable rods 204 are hinged to the hinge seat 203. For example, in this embodiment of the invention, the number of movable rods 204 is eight. The eight movable rods 204 are evenly distributed circumferentially, and each movable rod... Each end of 204 away from the hinge seat 203 is hinged to a movable seat 205, and a slider 209 is connected to the lower side of the movable seat 205; eight slide rails 208 corresponding to the sliders 209 are installed on the upper surface of the positioning seat 100, and the sliders 209 are slidably embedded in the corresponding slide rails 208; a positioning block 206 is connected to the outside of the movable seat 205, and the outer surface of the positioning block 206 is arc-shaped, and its curvature is consistent with the inner ring curvature of the flange 400; an anti-slip pad is also installed on the outside of the positioning block 206, and the anti-slip pad is made of rubber.

[0032] Specifically, when positioning the flange 400, the flange 400 is first placed on the top surface of the positioning seat 100 through the clamping mechanism 200 via the central hole. Then, the drive mechanism 202 is activated to rotate the rotating shaft 201. Since the rotating shaft 201 is threadedly connected to the hinge seat 203, the rotating shaft 201 can drive the hinge seat 203 to move downward on the rotating shaft 201. The hinge seat 203 then drives the moving seat 205 to move towards the inner ring surface of the flange 400 via the movable rod 204. The moving seat 205 then drives the positioning block 206 to press tightly against the inner ring of the flange 400, thereby achieving the positioning of the flange 400.

[0033] Please see Figure 3-6 The upper part of the hinge seat 203 is equipped with a connecting cylinder 207, which is located outside the rotating shaft 201. The connecting cylinder 207 is detachably connected to a dust removal mechanism 300. The dust removal mechanism 300 includes an air cylinder 301. The lower end of the air cylinder 301 is internally threaded and sleeved on the connecting cylinder 207. Therefore, rotating the air cylinder 301 can detach the air cylinder 301 from the connecting cylinder 207. At the same time, the air cylinder 301 is provided with anti-slip texture on the outside to facilitate the user's rotation of the air cylinder 301. The lower end of the air cylinder 301 is equipped with a cover 304, which is shaped like a pot lid and is fixedly connected to the lower exterior of the air cylinder 301. An airbag ball 305 is provided on the outer surface of the cover 304. The lower end of the airbag ball 305 is fixedly connected to the bottom edge of the cover 304, and the upper end of the airbag ball 305 is fixedly connected to the outer wall of the air cylinder 301. Multiple air holes are provided on the cylinder wall of the air cylinder 301, and the airbag ball 305 communicates with the interior of the air cylinder 301 through these air holes. Multiple airbag leaves 306 are connected to the lower edge of the airbag ball 305. The multiple airbag leaves 306 are evenly distributed and communicate with the airbag ball 305.

[0034] An inflation mechanism is installed at the top of the air cylinder 301 to supply air into the air cylinder 301. When the inflation mechanism is activated, it can support the airbag bulb 305 and the airbag leaf 306. The inflation mechanism includes a piston plate 302 and a cylinder 303. The piston plate 302 is located inside the air cylinder 301, and the cylinder 303 is located at the top of the air cylinder 301. The top of the air cylinder 301 is also provided with a pressure relief hole. The extended end of the cylinder 303 is movably inserted through the top wall of the air cylinder 301 and connected to the piston plate 302 inside the air cylinder 301.

[0035] In detail, after the flange 400 is placed on the positioning seat 100 and positioned by the clamping mechanism 200, the dust removal mechanism 300 is taken out and connected to the outside of the connecting cylinder 207 by rotating the air cylinder 301, with the bottom of the air cylinder 301 pressing against the hinge seat 203. At this time, the bottom edge of the cover 304 abuts against the edge of the upper surface of the flange 400, and the inflation mechanism is in a state of suction into the air cylinder 301, so that the airbag ball 305 is tightly attached to the surface of the cover 304, and the airbag leaf 306 is tightly attached to the outside of the cover 304. At this time, the edge of the flange 400 can be drilled with screw holes. A large amount of dust will be generated during the drilling process. Some of this dust will fly onto the surface of the airbag ball 305, and some will fall on the edge of the drilled hole of the flange 400. After the drilling is completed, the cylinder 303 in the inflation mechanism is started, which drives the piston plate 302 to move up and down in the air cylinder 301. When the piston plate 302 moves downward, it will push into the cover 304. Inflation causes the cover 304 to inflate rapidly, and simultaneously, air enters and expands the airbag bulb 305. When the piston plate 302 moves upward, it resumes the intake state, causing the airbag bulb 305 and airbag leaf 306 to contract and press tightly together. During the reciprocating motion of the piston plate 302, the airbag bulb 305 and airbag leaf 306 repeatedly inflate and expand. In this process, the airbag bulb 305 ejects surface dust and debris along the cover 304, while the airbag leaf 305... During the support process, airflow is generated at the edge of the drilled hole of flange 400, thereby blowing away the dust and debris at the edge of the air hole of flange 400. At this time, the dust and debris on flange 400 can be cleaned. Under the protection of airbag ball 305, the surface of flange 400 will not be contaminated with dust and debris. The airflow at the edge of the drilled hole of flange 400 can remove dust and debris. No manual cleaning or transfer to the next cleaning procedure is required. It saves time and effort, is convenient and quick, and has a good cleaning effect.

[0036] Working principle of the invention:

[0037] When drilling threaded holes on the edge of flange 400, flange 400 is first placed on the top surface of positioning seat 100 through the clamping mechanism 200 via the central hole. Then, the drive mechanism 202 is activated to rotate shaft 201. Since shaft 201 is threadedly connected to hinge seat 203, shaft 201 can drive hinge seat 203 to move downwards on shaft 201. Hinge seat 203 then drives moving seat 205 towards the inner ring surface of flange 400 via movable rod 204. Moving seat 205 then drives positioning block 206 to press tightly against the inner ring of flange 400, thereby... Positioning of flange 400 is achieved; then, dust removal mechanism 300 is taken, and air cylinder 301 is connected to the outside of connecting cylinder 207 by rotating air cylinder 301, with the bottom of air cylinder 301 pressing against hinge seat 203. At this time, the bottom edge of cover shell 304 abuts against the edge of upper surface of flange 400, and the inflation mechanism is in a state of suction inside air cylinder 301, so that airbag ball 305 is tightly attached to the surface of cover shell 304, and airbag leaf 306 is tightly attached to the outside of cover shell 304; at this time, screw holes can be drilled on the edge of flange 400. A large amount of dust will be generated during the drilling process, some of which will fly to On the surface of the airbag ball 305, a portion rests at the edge of the drilled hole in the flange 400. After drilling is completed, the cylinder 303 in the inflation mechanism is activated, causing the piston plate 302 to move up and down in the air cylinder 301. When the piston plate 302 moves downward, it inflates the cover 304, causing the cover 304 to bulge rapidly. At the same time, the airbag ball 305 is also rapidly inflated. When the piston plate 302 moves upward, it returns to the intake state, causing the airbag ball 305 and the airbag leaf 306 to contract to a tight fit. During the reciprocating motion of the piston plate 302, the airbag ball 305 and the airbag leaf 306... The system repeatedly inflates and expands. During this process, the airbag ball 305 ejects dust and debris from the surface along the cover 304, while the airbag blade 306 generates airflow at the edge of the drilled hole in the flange 400 during expansion, thus blowing away the dust and debris at the edge of the air hole in the flange 400. At this time, the dust and debris on the flange 400 can be cleaned. Under the protection of the airbag ball 305, the surface of the flange 400 will not be contaminated with dust and debris. The airflow at the edge of the drilled hole in the flange 400 can remove dust and debris. No manual cleaning or transfer to the next cleaning procedure is required, which saves time and effort, is convenient and quick, and has a good cleaning effect.
