Description

Technical Field

[0002] During the processing of gear shafts, it is often necessary to adjust and clamp the gear shafts to accurately position them, thereby ensuring processing accuracy and operational safety. The existing clamping device is mainly composed of a bracket frame, a cylinder, a guide rod, a support center, etc. This clamping device can achieve the clamping of most castings, thereby allowing the gear shafts to be ground, drilled, processed, etc.

[0003] However, since the end of the clamping device is in direct contact with the gear shaft, when the gear shaft is applied with force or released, there will be relative sliding friction between the clamping part and the gear shaft, which are also made of metal. This can easily lead to defects such as scratches or even pits on the surface of the gear shaft, causing product rework, reducing product quality and production efficiency. At the same time, metal debris will be generated when drilling the gear shaft. If not handled in time, it will affect the working environment of the drilling operation. A large amount of metal debris and powder will be inhaled by the human body, causing health hazards. Summary of the Invention

The springs work together to elastically press and cushion the vibration generated by the drilling operation. At the same time, under the guidance of the downward movement of the pressure ring, the support rod and spring 2 on each telescopic rod are elastically tilted, thereby driving the contact plate on the support rod to press against the inner wall of the gear shaft near the top. Since the contact plate is also made of natural rubber, the inner wall of the gear shaft will not be damaged when it is limited and pressed. The multi-level limit pressing can avoid sliding friction between the gear shaft and the workpiece base and the pressure plate.

At the same time, the sucked debris powder will pass through the annular tube into the drawer in the collection box. Finally, the drawer and the collection box can be separated by pulling the pull handle, and the debris powder in the drawer can be processed to improve the working environment.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] like Figures 1 to 7 As shown, the present invention provides an automatic pressing tool based on gear shaft drilling, including a machine base 1, four workpiece bases 11 are fixedly connected to the machine base 1, a cylindrical groove is opened in the middle of the machine base 1, a T-shaped pole 12 is fixedly connected in the cylindrical groove, and pressure plates 13 are fixedly connected to the outer walls of the bottom ends of both sides of the T-shaped pole 12. A pressure groove 14 is opened on the outer walls of the bottom ends of both sides of each pressure plate 13, and a drill hole is opened at the top of each pressure groove 14, and further comprising:

[0031] The pressing part 2 is located in the pressing groove 14 of each workpiece base 11. The pressing part 2 includes three telescopic rods 21. A first elastic structure is provided in the inner wall of each telescopic rod 21, a positioning structure is provided on one end of each telescopic rod 21, and a limiting structure is provided on the other end of each telescopic rod 21. A second elastic structure is provided on the outer wall of each telescopic rod 21, and a pressing structure is provided on the bottom end of each second elastic structure. A protective structure is provided below each pressing structure.

[0032] The chip cleaning part 3 is located on the outer wall of the machine base 1. The chip cleaning part 3 includes a collecting box 31. A pulling structure is provided in the collecting box 31. A suction structure is also provided in the collecting box 31. A pipeline structure is provided on the suction structure.

[0033] The above scheme is adopted: by placing the gear shaft to be drilled into the workpiece base 11 in advance, contacting the rubber mold 230 and the rubber protrusion 231 installed in the workpiece base 11, thereby preventing the gear shaft from being damaged when being limited and pressed, and then the T-shaped electric pole 12 moves downward, driving the pressure plate 13 to move downward synchronously, and the top of the workpiece base 11 can be covered, thereby squeezing the pressure ring 23 in the pressure groove 14, and the downward pressure ring 23 will squeeze and contact the top of the gear shaft. At the same time, the squeezed pressure ring 23 will also be forced to squeeze the multiple connected telescopic rods 21, through the two semicircular support plates 25 and the cross bar 26, driving the arc plate 24 to rotate a certain amplitude when the telescopic rod 21 moves downward and squeezes, and the spring 1 22 in each telescopic rod 21 is squeezed through the downward process to deform it, and the spring 1 22 plays an elastic pressure role. In the process, the vibration generated by the drilling operation can be impact-buffered. At the same time, under the guidance of the downward movement of the pressure ring 23, the support rod 28 on each telescopic rod 21 and the spring 27 will be elastically tilted, thereby driving the support plate 29 on the support rod 28 to press against the inner wall of the gear shaft near the top. The multi-level limiting pressure can avoid sliding friction between the gear shaft and the workpiece base 11 and the pressure plate 13. When the drilling operation is performed at the center position of the pressure ring 23, the micro pump 34 in the collection box 31 needs to be started synchronously to pass through the suction cups 37 on multiple L-shaped tubes 36 to absorb and collect the debris powder generated by the drilling. The sucked debris powder will pass through the annular tube 35 into the drawer 32 in the collection box 31. Finally, the drawer 32 and the collection box 31 can be separated by pulling the pull handle 33, and the debris powder in the drawer 32 can be processed.

[0034] The first elastic structure is a spring 22, both ends of which are fixedly connected to the inner wall of the telescopic rod 21, and the positioning structure is a pressure ring 23, the outer wall of the pressure ring 23 is hinged to one end of the telescopic rod 21, and the pressure ring 23 is specifically made of natural rubber. The limiting structure is composed of an arc plate 24 and a semicircular support plate 25 that is fitted and connected to the outer walls of both ends of the arc plate 24. A cross bar 26 is fixedly connected between the two semicircular support plates 25, and one end of the arc plate 24 is fixedly connected to the outer wall of the other end of the telescopic rod 21. The outer wall of one end of each semicircular support plate 25 is fixedly connected to the inner wall of the pressing groove 14, and the cross bar 26 and the arc plate 24 are movably connected.

[0035] By adopting the above scheme, the pressure ring 23 will be squeezed to the multiple connected telescopic rods 21, and through the two semicircular support plates 25 and the cross bar 26, it drives the arc plate 24 to rotate to a certain extent when the telescopic rod 21 moves downward and is squeezed. During the downward movement process, the spring 1 22 in each telescopic rod 21 is squeezed to deform it. In the process of the spring 1 22 playing the role of elastic pressure, it can also cushion the impact of the vibration generated by the drilling operation.

[0036] The second elastic structure is spring 27, the top of spring 27 is fixedly connected to the outer wall of the telescopic rod 21, the pressing structure is composed of a support rod 28 and a support plate 29 fixedly connected to one end of the support rod 28, the bottom end of spring 27 is fixedly connected to the outer wall of the support rod 28, and the other end of the support rod 28 is hinged to the telescopic rod 21, and the protective structure is composed of a rubber mold 230 and a plurality of rubber protrusions 231 fixedly connected to the inner wall of the rubber mold 230, and the outer wall of the rubber mold 230 is fixedly connected to the inner wall of the workpiece base 11.

[0037] Adopting the above scheme: under the guidance of the downward movement of the pressure ring 23, the support rod 28 on each telescopic rod 21 and the spring 27 will be elastically tilted, thereby driving the resistance plate 29 on the support rod 28 to press against the inner wall of the gear shaft near the top. Since the resistance plate 29 is also made of natural rubber, the inner wall of the gear shaft will not be damaged when it is limited and pressed. The multi-level limit pressing can avoid sliding friction between the gear shaft and the workpiece base 11 and the pressure plate 13. The rubber mold 230 and the rubber protrusion 231 installed in the workpiece base 11 can prevent the surface of the gear shaft from being damaged when it is limited and pressed, and at the same time increase the friction between the inner wall of the rubber mold 230 and the gear shaft, thereby achieving an anti-slip effect.

[0038] The pulling and pulling structure consists of a drawer 32 and a pulling handle 33 fixedly connected to the outer wall of one end of the drawer 32. The drawer 32 passes through the inner and outer walls of one end of the collecting box 31, and is slidably engaged with the inner wall of the collecting box 31. The collecting box 31 is fixedly connected to the outer wall of one end of the base 1. The suction structure consists of a micro pump 34 and a plurality of suction cups 37. The top outer wall of the micro pump 34 is fixedly connected to the top inner wall of the collecting box 31. The pipeline structure consists of an annular tube 35 and four L-shaped tubes 36 that are fixedly connected to the top of the annular tube 35. The other end of each L-shaped tube 36 is fixedly connected to one end of the suction cup 37. One end of the annular tube 35 is fixedly connected to one end of the collecting box 31 and is fixedly connected to one end of the micro pump 34.

[0039] Adopting the above scheme: when drilling through the center position of the pressure ring 23, it is necessary to synchronously start the micro pump 34 in the collection box 31 so that it passes through the suction cups 37 on multiple L-shaped tubes 36 to suck and collect the debris powder generated by drilling, eliminating the trouble of manual cleaning, which is safe and reliable. At the same time, the sucked debris powder will pass through the annular tube 35 into the drawer 32 in the collection box 31. Finally, the drawer 32 and the collection box 31 can be separated by pulling the pull handle 33, and the debris powder in the drawer 32 can be processed to improve the working environment.

[0040] The working principle and use process of the present invention:

[0041] The gear shaft to be drilled is placed in the workpiece base 11 in advance, and contacts the rubber mold 230 and the rubber protrusion 231 installed in the workpiece base 11. This can prevent the gear shaft from being damaged when it is limited and pressed. At the same time, it has the effect of increasing the friction between the inner wall of the rubber mold 230 and the gear shaft, which has an anti-slip effect. Then, the T-shaped electric pole 12 moves downward, driving the pressure plate 13 to move downward synchronously, and the top of the workpiece base 11 can be covered, thereby squeezing the pressure ring 23 in the pressure groove 14. The downward pressure ring 23 will squeeze and contact the top of the gear shaft. At the same time, the squeezed pressure ring 23 will also be forced to squeeze the multiple connected telescopic rods 21. Through the two semicircular support plates 25 and the cross bar 26, the arc plate 24 is driven to rotate a certain amplitude when the telescopic rod 21 moves downward. The spring 1 22 in each telescopic rod 21 is squeezed and deformed during the downward movement. The spring 1 22 plays an elastic role in the pressure resistance and can also cushion the vibration generated by the drilling operation.

[0042] At the same time, under the guidance of the downward movement of the pressure ring 23, the support rod 28 on each telescopic rod 21 and the spring 27 are elastically tilted, thereby driving the support plate 29 on the support rod 28 to press against the inner wall of the gear shaft near the top. Since the plate 29 is also made of natural rubber, the inner wall of the gear shaft will not be damaged when it is limited and pressed. The multi-level limit pressing can avoid sliding friction between the gear shaft and the workpiece base 11 and the pressure plate 13.

[0043] Then, when drilling is performed through the center position of the pressure ring 23, the micro pump 34 in the collection box 31 needs to be started synchronously so that it passes through the suction cups 37 on multiple L-shaped tubes 36 to suck and collect the debris powder generated by drilling, eliminating the trouble of manual cleaning, which is safe and reliable. At the same time, the sucked debris powder will pass through the annular tube 35 into the drawer 32 in the collection box 31. Finally, the drawer 32 and the collection box 31 can be separated by pulling the pull handle 33, and the debris powder in the drawer 32 can be processed to improve the working environment.
