Description

Technical Field

[0001] The utility model relates to the technical field of shift fork production, in particular to a shift fork surface deburring device. Background Art

[0002] The shift fork is a major part of the automobile shift mechanism. During the production process of the shift fork, the surface of the shift fork needs to be processed to remove burrs and improve product quality. The existing grinding wheel grinding mechanisms for shift fork production on the market have the advantages of simple structure and convenient operation. However, most of the existing grinding wheel grinding mechanisms for shift fork production are fixed grinding and cannot grind multiple positions of the shift fork. If multiple positions of the shift fork need to be grinded, the product needs to be re-clamped, which is a waste of time and energy.

[0003] Chinese Patent: CN213164633U, which discloses a grinding wheel grinding mechanism for fork production. The grinding wheel grinding mechanism for fork production can conveniently clamp the fork by setting a first electric push rod, and can conveniently push the grinding head to move downward to grind the fork by setting a second electric push rod. By setting an electric slide rail, it can conveniently drive the grinding head to move back and forth, so as to perform transposition processing and grinding on the front and back sides of the fork. However, although the above-mentioned grinding mechanism can grind a large area of ​​a single side of the fork when in use, in actual use, burrs will exist on both sides and the side surfaces due to friction. After the above-mentioned grinding mechanism grinds a single side, the fork is manually removed, and the grinding surface of the fork is adjusted before the remaining sides of the fork can be deburred. Therefore, in actual use, the fork needs to be removed and re-fixed for many times to complete the deburring of multiple sides of the fork, which will waste a lot of time during use, thereby affecting the processing efficiency.

[0004] Based on this, a fork surface deburring device is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0028] The clamping assembly includes a bidirectional screw 19, which is arranged in a threaded hole on one side of two linkage plates 17, and the bidirectional screw 19 is rotatably arranged in a mounting hole on the inner side of the workbench 11.

[0029] The driving assembly includes a reciprocating screw 28, which is arranged in a thread hole at the upper end of the mounting frame 24.

[0030] The cleaning mechanism comprises a first brush roller 21 and a second brush roller 25, wherein the axes of the first brush roller 21 and the second brush roller 25 are arranged vertically, and the first brush roller 21 and the second brush roller 25 are rotatably arranged on the inner sides of the first fixed frame and the second fixed frame respectively, and a driven wheel on the rotating shaft at one end of the first brush roller 21 is connected to a driving wheel on the output shaft of the first motor 22 through a belt, and the first motor 22 is fixedly arranged on the upper end of the first fixed frame, and a rotating shaft at one end of the second brush roller 25 is fixedly connected to the output end of the second motor 26, and the second motor 26 is fixedly arranged on one side of the second fixed frame, and a first connecting rod and a second connecting rod are fixedly arranged on the first fixed frame and the second fixed frame respectively. The second connecting rod, the first connecting rod and the second connecting rod are respectively arranged in the two mounting holes on the inner side of the mounting frame 24. When in use, when it is necessary to remove burrs on the surface of the fork, start the first motor 22 and the second motor 26, and the first motor 22 and the second motor 26 respectively drive the first brush roller 21 and the second brush roller 25 to rotate, and then the reciprocating screw rod 28 drives the mounting frame 24 to move along the axial direction of the second guide slide bar 29, and the mounting frame 24 drives the first brush roller 21 and the second brush roller 25 to move, thereby cleaning the burrs on both sides of the fork. It is worth noting that the first brush roller 21 and the second brush roller 25 here can be replaced with other grinding parts according to actual conditions.

[0031] One end of the first connecting rod and the second connecting rod are fixedly connected to the output ends of the first electric push rod 23 and the second electric push rod 27 respectively. The first electric push rod 23 and the second electric push rod 27 are both fixedly arranged on the mounting frame 24. When in use, the first electric push rod 23 and the electric push rod 27 are electrically connected to the external control component, so that when the protrusion and the arc-shaped outer side of the shift fork are moved, the first electric push rod 23 and the second electric push rod 27 respectively drive the first brush roller 21 and the second brush roller 25 to move, so that the burrs on the outer side of the shift fork can be completely cleaned.

[0032] The conversion mechanism includes a worm wheel 36, two of the worm wheels 36 are respectively fixed on two sleeve shafts 16, a worm 37 is meshed on the worm wheel 36, and a third rotating plate is rotatably provided on the rotating shafts at both ends of the worm 37, and the third rotating plate is fixed on the upper end of the workbench 11, and a friction wheel 32 is rotatably provided on the rotating shaft at one end of the worm 37, and both sides of the friction wheel 32 are tightly provided with limit plates, and the two limit plates are fixed on the rotating columns at one end of the worm 37, and a plurality of ratchet teeth 33 are fixed on the inner side of the friction wheel 32, and the fixed shaft between the two limit plates is connected to the ratchet teeth 33. A pawl 34 is rotatably provided at the position corresponding to position 33, and a torsion spring 35 is provided inside the pawl 34, and one end of the torsion spring 35 is fixedly connected to the fixed shaft, and a stop plate is closely attached to one side of the pawl 34, and the stop plate is fixedly provided on the rotating shaft at one end of the worm 37. Friction plates 31 are frictionally provided on the friction wheels 32, and the two friction plates 31 are respectively fixedly provided on both sides of the mounting frame 24. When in use, when the first brush roller 21 and the second brush roller 25 finish cleaning one side of the fork and detach from the fork, the friction plate 31 moves with the mounting frame 24, so that one friction plate 31 rubs against one friction wheel 32. The friction wheel 32 rotates, and when the friction wheel 32 rotates, it drives several ratchets 33 to rotate, and the ratchets 33 move the pawl 34. Since a stop plate is tightly attached to one side of the pawl 34, the worm 37 rotates, and the worm 37 meshes with the worm wheel 36, so that the worm wheel 36 drives the sleeve shaft 16 to rotate. Since the two sliding shafts 15 clamp and fix the fork through the first fixed mold 13 and the second fixed mold 14 respectively, the sleeve shaft 16 drives the fork to rotate through the sliding shaft 15. When the mounting frame 24 moves to the end of the reciprocating screw rod 28, the fork rotates 180 degrees, and then the mounting frame 24 moves to the opposite direction. The pawl 34 rotates when the friction plate 31 and the friction wheel 32 rub against each other, causing the friction wheel 32 to rotate in the opposite direction. Since there is no stop plate on the other side of the pawl 34, the pawl 34 rotates. When the pawl 34 separates from one ratchet tooth 33, the pawl 34 rotates to the initial position under the action of the torsion spring 35, so that the worm 37 does not rotate, so that the mounting frame 24 drives the first brush roller 21 and the second brush roller 25 to clean the other two sides of the fork. When the mounting frame 24 drives the other friction plate 31 to fit closely with the other friction wheel 32, the sleeve shaft 16 rotates 180 degrees again in the same way, so that the fork rotates to the initial state.

[0033] Example 2

[0034] The difference from Example 1 is that a mounting hole is provided at the upper end of the workbench 11 corresponding to the position of the first fixed mold 13 and the second fixed mold 14, and a mesh plate 38 is fixed in the mounting hole. When in use, after the first brush roller 21 and the second brush roller 25 remove the burrs on the fork, the burr residue falls on the upper end of the mesh plate 38, and the mesh plate 38 allows the residue to fall through a plurality of mesh holes, thereby reducing the accumulation of residue on the upper end of the workbench 11.

[0035] A guide plate 39 is fixedly provided on the first guide slide bar 18 at a position corresponding to the position below the mesh plate 38, and the guide plate 39 is inclined. A collecting box 40 is provided at a position corresponding to one end of the guide plate 39 on one side of the workbench 11, and a support frame is symmetrically slidably provided on the bottom end of the collecting box 40, and the support frame is fixed on the inner side of the workbench 11. When in use, when burr residues pass through several mesh holes on the mesh plate 38 and fall to the upper end of the guide plate 39, the guide plate 39 is inclined so that the residues fall into the inside of the collecting box 40 for collection.

[0036] The above embodiment discloses a deburring device for the surface of a shift fork, wherein when the shift fork needs to be clamped and fixed, the transmission shaft 20 is rotated, and the transmission shaft 20 drives the bidirectional screw 19 to rotate through the active conical friction wheel. Under the action of the thread, the two linkage plates 17 drive the two sliding shafts 15 to move in opposite directions. The two sliding shafts 15 respectively drive the first fixed mold 13 and the second fixed mold 14 to move, thereby clamping and fixing the shift fork, starting the third motor 30, the first motor 22 and the second motor 26, and the output end of the third motor 30 drives the reciprocating screw 28 to rotate, and the reciprocating screw 28 and the mounting frame 24 The upper end thread hole cooperates so that the mounting frame 24 reciprocates along the axis direction of the second guide slide bar 29, and the first motor 22 and the second motor 26 respectively drive the first brush roller 21 and the second brush roller 25 to rotate, and then the reciprocating screw rod 28 drives the mounting frame 24 to move along the axis direction of the second guide slide bar 29, and the mounting frame 24 drives the first brush roller 21 and the second brush roller 25 to move, so as to clean the burrs on both sides of the fork. After the first brush roller 21 and the second brush roller 25 finish cleaning one side of the fork and separate from the fork, the friction plate 31 moves with the mounting frame 24, so that one friction plate 31 rubs against one friction wheel 32, so that the friction plate 31 is moved. The rubbing wheel 32 rotates, and when the friction wheel 32 rotates, it drives several ratchets 33 to rotate, and the ratchets 33 move the pawl 34. Since a stop plate is tightly attached to one side of the pawl 34, the worm 37 rotates, and the worm 37 meshes with the worm wheel 36, so that the worm wheel 36 drives the sleeve shaft 16 to rotate. Since the two sliding shafts 15 clamp and fix the fork through the first fixed mold 13 and the second fixed mold 14 respectively, the sleeve shaft 16 drives the fork to rotate through the sliding shaft 15. When the mounting frame 24 moves to the end of the reciprocating screw 28, the fork rotates 180 degrees, and then the mounting frame 24 moves in the opposite direction. At this time, the friction plate 31 and the friction plate 32 are engaged with each other. The friction of the wheel 32 causes the friction wheel 32 to rotate in the opposite direction. Since there is no stop plate on the other side of the pawl 34, the pawl 34 rotates. When the pawl 34 separates from one ratchet tooth 33, the pawl 34 rotates to the initial position under the action of the torsion spring 35, so that the worm 37 does not rotate, so that the mounting frame 24 drives the first brush roller 21 and the second brush roller 25 to clean the other two sides of the fork. When the mounting frame 24 drives the other friction plate 31 to fit tightly with the other friction wheel 32, the sleeve shaft 16 is rotated 180 degrees again in the same way, so that the fork rotates to the initial state, and then the staff reverses the transmission shaft 20 to remove the fork.

[0037] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
