Description

Technical Field

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

[0002] When machining tooth grooves on mechanical parts, a tooth drawing device is usually used to machine the mechanical parts into the required tooth profile.

[0003] In the field of tooth groove processing of mechanical parts, the traditional processing method is mainly achieved with the help of tooth pulling devices. The tooth pulling device, with its unique tooth shape design, matches the tooth shape required by the workpiece to be processed. The required tooth shape is cut on the workpiece through the up and down pulling action of the tool.

[0004] When machining existing gear teeth, the coolant usually flows in a fixed direction and is sprayed in a single direction, which makes it easy for the coolant to cool the cutting part of the tool or workpiece unevenly. The single flow direction also easily causes the accumulation of chips, which is not conducive to the machining of the machining area. Therefore, the single-direction flow of coolant cannot meet the needs of the existing gear drawing device. Summary of the Invention

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0031] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0032] Example: Refer to Figures 1-8 , which is the first embodiment of the present invention, provides a mechanical parts processing equipment, including a gear broaching machine 1, the gear broaching machine 1 is provided with a gear broaching assembly 11, a tool fixing end of the gear broaching assembly 11 is provided with a workpiece fixing plate 12, and a chip liquid guide plate 13 is fixed to the bottom side of the workpiece fixing plate 12;

[0033] The top side of the tool fixed end of the tooth drawing assembly 11 is connected to a fixing ring 2, and 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, and one end of the support plate 23 is connected to a rotating platform 22. The rotating platform 22 is fixed on the outer wall of the tooth drawing machine 1, and a guide pipe 24 is installed on one side of the support plate 23. A storage box 25 is installed on the outer wall of the tooth drawing machine 1, and a hose 26 is installed at the bottom of the storage box 25. When the transmission rod body 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 then the guide pipe 24 connected to the support plate 23 swings left and right, so that the outflowing coolant also swings left and right, like a dynamic "sweeper", which can better flush the chips away from the processing area, while improving the cooling and lubrication effects.

[0034] Specifically, one end of the hose 26 is connected to one end of the guide tube 24, the inner wall of the hose 26 is connected to the rubber bladder 3, the outer wall of the rubber bladder 3 is installed with an air inlet valve 31, the outer wall of the rubber bladder 3 is installed with an air extraction pipe 32, the top of the support plate 23 is installed with an air extraction valve 33, and one end of the air extraction pipe 32 extends into the interior of the air extraction valve 33, the top of the air extraction valve 33 is installed with a piston rod 331, the outer wall of the air extraction valve 33 is installed with a group of one-way air outlet valves 332, the outer wall of the air extraction valve 33 is installed with a group of directional air inlet valves 333, and the directional air inlet valves 333 are connected to the air extraction pipe 32. If the cutting speed becomes faster, the piston rod The frequency of the pressure on 331 becomes faster, making the air intake speed of the rubber bladder 3 slightly lower than the air extraction speed. The rubber bladder 3 is contracted, widening the flow path inside the hose 26, thereby increasing the flow rate of the coolant in the storage box 25 to the guide tube 24; on the contrary, if the processing speed slows down, the rubber bladder 3 relies on its own elasticity to restore to its original shape. This structure can regulate the coolant flow rate according to the processing speed requirements to avoid excessive waste of coolant. The air extraction effect of the air extraction valve 33 is determined by the variable of the workpiece processing speed. When processing different materials, the processing speed is also very different. The speed difference is completely sufficient to cause the air extraction valve 33 to deform the rubber bladder 3.

[0035] Furthermore, an air injection part 4 is installed on the outer wall of the fixing ring 2, and the tooth pulling assembly 11 includes a fixed platform 111 for supporting the rod body. An air cavity 41 is provided inside the fixed platform 111, and 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. An injection column 44 is installed on the outer wall of the support plate 23, and the guide tube 24 is connected to the hose 26 through the injection column 44. An air inlet pipe 45 is installed on the outer wall of the air injection part 4, and the other end of the air inlet pipe 45 is connected to the air cavity 41. During the tooth groove cutting process, the cutting action will drive the air injection part 4 to store air and inject pressure into the air cavity 41, and each cutting action is The connecting rod 21 will touch the tooth plate 51 once, and the tooth plate 51 moves upward to drive 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 spring block 54 to move, so that the spring block 54 drives the moving plate to move one unit to the side of the cover plate 43. When the contact rod 57 connected to the moving plate squeezes the push rod 58, the push rod 58 opens the cover plate 43, and the pressurized gas in the air cavity 41 is released through the connecting channel 42 and injected into the guide tube 24 through the injection column 44, so that the coolant in the guide tube 24 is suddenly ejected, and the pressurized coolant is sprayed on the tool, completely washing away the debris on the tool, preventing the residual chips from affecting the subsequent processing accuracy.

[0036] Furthermore, an external one-way valve 441 is installed on the outer wall of the 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 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 direction of the guide tube 24, ensuring that the pressurized coolant can be smoothly sprayed out when the gas is released.

[0037] Furthermore, the outer one-way valve 441 and the inner one-way valve 442 have the same structure as the one-way outlet valve 332 , the directional air inlet valve 333 and the air inlet pipe 45 , and both achieve one-way gas flow through the same structure.

[0038] Furthermore, a counting assembly 5 is provided inside the fixed platform 111, and the counting assembly 5 includes a tooth plate 51 installed inside the fixed platform 111, and a gear 52 meshing with the tooth plate 51 is installed on one side of the tooth plate 51, and a rotating wheel 53 is installed on the end of the gear 52 through the rod body, and a spring block 54 is installed on the outer wall of the rotating wheel 53, and a moving rod 55 is installed on the top of the rotating wheel 53, and a locking block 56 is installed on the top of the moving rod 55, and a touch-pressure rod 57 is installed on the end of the moving rod 55, and a push rod 58 is installed on one side of the touch-pressure rod 57, and the push rod 58 is located on the bottom side of the cover plate 43, and when the push rod 58 lifts the cover plate 43, its locking block 56 is also lifted by the unlocking part of the mobile terminal, so that when the pressure relief is completed and restored, its moving rod 55 can be smoothly reset, so that reciprocating work can be performed.

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

[0040] Furthermore, the teeth of the tooth plate 51 are oblique teeth, so that the tooth plate 51 can drive the gear 52 to rotate upward, but will not drive the gear 52 to rotate downward. The locking block 56 is embedded in the top of the moving rod 55 through a spring to achieve one-way locking of the moving rod 55. The tooth plate 51 can only drive the gear 52 to rotate when it moves upward, and will not affect the gear 52 when the tooth plate 51 moves downward, thereby ensuring the accuracy of the counting. At the same time, the locking block 56 is embedded in the top of the moving rod 55 through a spring to achieve one-way locking of the moving rod 55, preventing the moving rod 55 from moving in a non-triggered state, thereby ensuring the stability and reliability of the counting component 5.

[0041] Operation process: During processing, the tooth-pulling assembly 11 uses the corresponding toothed tool to cut the workpiece on the workpiece fixing plate 12 up and down. During the cutting process, the transmission rod body of the tooth-pulling 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, and the up and down movement of the fixed ring 2 drives the connecting rod 21 to swing up and down. The swinging of the connecting rod 21 drives the support plate 23 to rotate up and down at a certain angle on the rotating platform 22, thereby causing the support plate 23 to connect the guide tube 24 to swing left and right, so that the swinging guide tube 24 will swing the outflowing coolant. At this time, the swinging coolant back and forth can act like a dynamic "sweeper", removing the chips from the workpiece. The processing area is better flushed away, and the coolant swinging back and forth can better contact the cutting part of the toothed tool, thereby improving the cooling and lubrication effect. In the reciprocating cutting of the tool, if the cutting speed becomes faster, the up and down swinging speed of the connecting rod 21 also becomes faster. At this time, the piston rod 331 on the exhaust valve 33 on the top side of the connecting rod 21 is pressed at a frequency that also becomes faster, so that the air intake speed of the rubber bladder 3 is slightly lower than the exhaust speed. At this time, the internal air pressure of the rubber bladder 3 gradually decreases, and the rubber bladder 3 will gradually flatten, and the flattening direction is from the center area to the inner wall of the pipe. At this time, the flow path inside the hose 26 gradually becomes larger, so that the coolant in the storage box 25 flows The coolant flow to the guide tube 24 also increases accordingly, and when the processing speed slows down, the rubber bladder 3 can rely on its own elasticity to restore its original shape. This structure can adjust the coolant flow according to demand, reducing excessive waste of cooling, and when the workpiece fixing plate 12 rotates to change the workpiece cutting position, the tool and the workpiece are separated at this time, which is the best cleaning state. In the previous tooth groove cutting process, the cutting action of the tooth groove will drive the gas injection part 4 to store gas and pressurize the inside of the air cavity 41, and each cutting action will cause the connecting rod 21 to touch the tooth plate 51 once, and the tooth plate 51 moves upward to drive the gear 52 to rotate, and the rotation of the gear 52 drives the rotating wheel 53 to rotate, and the rotation The rotation of the wheel 53 drives the spring block 54 to move, so that the spring block 54 drives the movable plate to move one unit to the side of the cover plate 43. When it moves to the specified number of times (the specified number is consistent with the number of times the tooth groove needs to be repeatedly cut), the contact pressure rod 57 connected to the movable plate squeezes the push rod 58, and the push rod 58 opens the cover plate 43, so that the gas under continuous pressure in the air cavity 41 can be released through the connecting channel 42. At this time, the gas is injected through the injection column 44, so that the coolant in the injection column 44 and the guide tube 24 is suddenly ejected, so that the pressurized coolant is sprayed on the tool, so that the debris on the tool is completely washed away, avoiding the residual chips affecting the subsequent processing accuracy when changing the cutting part.
