Description

Technical Field

[0001] The present invention relates to the technical field of accessory processing, and in particular to a mechanical accessory processing device. Background Art

[0002] When machining a tooth-shaped groove of a mechanical accessory, a broaching device is usually used to machine the mechanical accessory into a required tooth shape.

[0003] In the field of machining tooth-shaped grooves of mechanical accessories, traditional machining methods mainly rely on broaching devices to achieve. The broaching device, with its unique tooth shape design, matches the tooth shape required by the workpiece to be machined. Through the up and down pulling action of the tool, the required tooth shape is cut on the workpiece.

[0004] When machining existing gear teeth, the coolant usually flows in a constant direction and is fixedly sprayed in a single direction. This makes it easy for the coolant to cool unevenly on the cutting part of the tool or the workpiece, and the single flow direction also easily causes the accumulation of chips, which is not conducive to the machining in the machining area. Therefore, the flow of the coolant in a single direction cannot meet the use of existing broaching devices. Summary of the Invention

Detailed implementation manners

[0029] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0032] Furthermore, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0033] Embodiment: Refer to Figures 1-8, which is the first embodiment of the present invention. This embodiment provides a mechanical fitting processing device, including a gear hobbing machine 1. The gear hobbing machine 1 is provided with a gear hobbing assembly 11. A workpiece fixing plate 12 is arranged at the tool fixing end of the gear hobbing assembly 11. A chip coolant guiding plate 13 is fixed to the bottom side of the workpiece fixing plate 12; A fixing ring 2 is connected to the top side of the tool fixing end of the gear hobbing assembly 11. One end of the outer wall of the fixing ring 2 is movably connected to a connecting rod 21 through a pin shaft. One end of the connecting rod 21 is connected to a support plate 23. One end of the support plate 23 is connected to a rotating platform 22. The rotating platform 22 is fixed to the outer wall of the gear hobbing machine 1. A guiding pipe 24 is installed on one side of the support plate 23. A storage tank 25 is installed on the outer wall of the gear hobbing machine 1. A hose 26 is installed at the bottom of the storage tank 25. When the driving rod moves up and down, the fixing ring 2 moves up and down accordingly, driving the connecting rod 21 to swing up and down, so that the support plate 23 rotates up and down at a certain angle on the rotating platform 22, and further makes the guiding pipe 24 connected to the support plate 23 swing left and right, so that the flowing coolant also swings left and right, like a dynamic "sweeper", which can better wash the chips away from the processing area and improve the cooling and lubrication effects at the same time.

[0034] Specifically, one end of the hose 26 is communicated with one end of the guiding pipe 24. A rubber bladder 3 is connected to the inner wall of the hose 26. An air inlet valve 31 is installed on the outer wall of the rubber bladder 3. An air extraction pipe 32 is installed on the outer wall of the rubber bladder 3. An air extraction valve 33 is installed on the top of the support plate 23, and one end of the air extraction pipe 32 extends into the interior of the air extraction valve 33. A piston rod 331 is installed on the top of the air extraction valve 33. A group of one-way air outlet valves 332 are installed on the outer wall of the air extraction valve 33. A group of pointing air inlet valves 333 are installed on the outer wall of the air extraction valve 33, and the pointing air inlet valve 333 is connected to the air extraction pipe 32. If the cutting speed becomes faster, the piston rod 331 is touched more frequently, so that the air inlet speed of the rubber bladder 3 is slightly lower than the air extraction speed, and the rubber bladder 3 is contracted, widening the flow path inside the hose 26, so that the flow rate of the coolant in the storage tank 25 flowing to the guiding pipe 24 becomes larger; on the contrary, if the processing speed becomes slower, the rubber bladder 3 returns to its original state by its own elasticity. This structure can adjust the coolant flow rate according to the processing speed requirements, avoid excessive waste of coolant, and the air extraction effect of the air extraction valve 33 is determined by the variable of the workpiece processing speed. When processing different materials, their processing speeds are quite different, and the speed difference is completely sufficient to cause the rubber bladder 3 to deform by the air extraction valve 33.

[0035] Further, an air injection member 4 is installed on the outer wall of the fixed ring 2. The pulling tooth assembly 11 includes a fixed platform 111 for supporting the rod body. An air cavity 41 is provided inside the fixed platform 111. A connecting channel 42 is provided on the inner bottom wall of the air cavity 41. A cover plate 43 is placed at the port of the connecting channel 42. A pressure injection column 44 is installed on the outer wall of the support plate 23. The diversion pipe 24 is communicated with the hose 26 through the pressure injection column 44. An air inlet pipe 45 is installed on the outer wall of the air injection member 4, and the other end of the air inlet pipe 45 is communicated with the air cavity 41. During the tooth groove cutting process, the cutting action will drive the air injection member 4 to store and inject pressure into the air cavity 41. Each cutting action will cause the connecting rod 21 to press the tooth plate 51 once. The tooth plate 51 moves upward to drive the gear 52 to rotate. The gear 52 rotates to drive the rotating wheel 53 to rotate. The rotating wheel 53 rotates to drive the elastic block 54 to move, so that the elastic block 54 drives the moving plate to move one unit toward the cover plate 43. When the pressure contact rod 57 connected to the moving plate presses the ejector rod 58, the ejector rod 58 opens the cover plate 43. The gas stored under pressure in the air cavity 41 is released through the connecting channel 42 and injected into the diversion pipe 24 through the pressure injection column 44, so that the coolant in the diversion pipe 24 is suddenly ejected. The pressurized coolant is sprayed on the tool, completely washing away the debris on the tool and preventing chip residue from affecting the subsequent processing accuracy.

[0036] Further, an external one-way valve 441 is installed on the outer wall of the pressure injection column 44, and the external one-way valve 441 is connected to one end of the connecting channel 42. An internal one-way valve 442 is installed at the end of the pressure injection column 44. The external one-way valve 441 and the internal one-way valve 442 ensure that the gas can only flow from the air cavity 41 to the diversion pipe 24, ensuring that when the gas is released, the pressurized coolant can be ejected smoothly.

[0037] Further, the external one-way valve 441, the internal one-way valve 442, the one-way air outlet valve 332, the pointing air inlet valve 333 and the air inlet pipe 45 have exactly the same structure and all achieve the unidirectional gas flow through the same structure.

[0038] Further, a counting assembly 5 is provided inside the fixed platform 111. The counting assembly 5 includes a tooth plate 51 installed inside the fixed platform 111. A gear 52 meshing with the tooth plate 51 is installed on one side of the tooth plate 51. A rotating wheel 53 is installed at the end of the gear 52 through a rod body. An elastic block 54 is installed on the outer wall of the rotating wheel 53. A moving rod 55 is installed at the top of the rotating wheel 53. A locking block 56 is installed at the top of the moving rod 55. A pressure contact rod 57 is installed at the end of the moving rod 55. A ejector rod 58 is installed on one side of the pressure contact rod 57, and the ejector rod 58 is located under the cover plate 43. When the ejector rod 58 lifts the cover plate 43, its locking block 56 is also lifted by the unlocking member of the mobile terminal, so that when the pressure is released and restored, the moving rod 55 can be reset smoothly, and thus can perform reciprocating work.

[0039] Further, a plurality of grooves for cooperating with the elastic block 54 are formed at the bottom of the moving rod 55, and a groove for cooperating with the locking block 56 is formed at the top of the moving rod 55.

[0040] Further, the tooth part of the toothed plate 51 is an inclined tooth, so that the upward movement of the toothed plate 51 can drive the gear 52 to rotate, and the downward movement of the toothed plate 51 will not drive the gear 52 to rotate. The locking block 56 is embedded in the top of the moving rod 55 through a spring to realize the one-way locking of the moving rod 55. The toothed plate 51 can only drive the gear 52 to rotate when moving upward, and the downward movement of the toothed plate 51 will not affect the gear 52, ensuring the accuracy of counting. At the same time, the locking block 56 is embedded in the top of the moving rod 55 through a spring to realize the one-way locking of the moving rod 55, preventing the moving rod 55 from moving in the non-trigger state and ensuring the stability and reliability of the counting component 5.

[0041] Operation process: During machining, the gear hobbing assembly 11 uses a corresponding tooth-shaped cutter to cut the workpiece on the workpiece fixing plate 12 up and down. During the cutting process, the transmission rod body of the gear hobbing assembly 11 moves up and down. At this time, the up and down movement of the transmission rod body drives the fixed ring 2 to move up and down. The up and down movement of the fixed ring 2 drives the connecting rod 21 to swing up and down. The swing of the connecting rod 21 drives the support plate 23 to rotate up and down at a certain angle on the rotating platform 22. As a result, the support plate 23 connected to the diversion pipe 24 swings left and right, causing the swinging diversion pipe 24 to swing the flowing coolant. At this time, the reciprocating coolant can act like a dynamic "sweeper" to better wash away the chips from the machining area. Moreover, the reciprocating coolant can better contact the cutting part of the tooth-shaped cutter, improving the cooling and lubrication effects. During the reciprocating cutting of the cutter, when the cutting speed increases, the up and down swing speed at the connecting rod 21 also increases accordingly. At this time, the piston rod 331 on the air extraction valve 33 on the top side of the connecting rod 21 is also pressed more frequently, causing the air intake speed of the rubber bladder 3 to be slightly lower than the air extraction speed. At this time, the internal air pressure of the rubber bladder 3 gradually decreases, and the rubber bladder 3 gradually flattens. The flattening direction is from the central area towards the inner wall of the pipe. At this time, the flow path inside the hose 26 gradually becomes larger, causing the coolant flow rate from the storage tank 25 to the diversion pipe 24 to also increase. When the machining speed slows down, the rubber bladder 3 can return to its original shape by relying on its own elasticity. This structure can adjust the coolant flow rate according to requirements, reducing excessive waste of cooling. When the workpiece fixing plate 12 rotates to change the cutting position of the workpiece, the cutter and the workpiece are in a separated state, which is the best cleaning state. During the cutting process of the previous tooth groove, the cutting action of the tooth groove drives the air injection part 4 to store and inject pressure into the internal air cavity 41. Each cutting action causes the connecting rod 21 to press the tooth plate 51 once. The upward movement of the tooth plate 51 drives the gear 52 to rotate. The rotation of the gear 52 drives the rotating wheel 53 to rotate. The rotation of the rotating wheel 53 drives the elastic block 54 to move, causing the elastic block 54 to drive the moving plate to move one unit towards the cover plate 43 side. When the specified number of times (the specified number of times is consistent with the number of times the tooth groove needs to be repeatedly cut) is reached, the pressure contact rod 57 connected to the moving plate presses the ejector rod 58, and the ejector rod 58 opens the cover plate 43, allowing the gas with continuous pressure in the air cavity 41 to be released through the connection channel 42. At this time, the gas is injected through the injection column 44, causing the coolant in the injection column 44 and the diversion pipe 24 to be suddenly ejected, spraying the pressurized coolant onto the cutter, completely washing away the debris on the cutter, and preventing the chip residue from affecting the subsequent machining accuracy when changing the cutting part.
