Description

Technical Field

[0001] This utility model mainly relates to the technical field of vent screw processing equipment, specifically to a high-efficiency drilling equipment for vent screws. Background Technology

[0002] The main function of the bleed screw used on brake calipers is to release air from the hydraulic lines of the brake system, preventing air in the hydraulic lines from affecting the normal operation of the brake system.

[0003] In the current drilling process for vent screws, a vibratory feeder is used in conjunction with a slide rail and a cylinder to feed and cut off the vent screws. The vent screws are then fed into a pneumatic fixture on the drilling equipment for drilling. When replacing the vent screw to be processed with the vent screw that has been drilled on the pneumatic fixture, due to the use of multiple pneumatic devices around the drilling equipment, an air blow pipe and an air valve are installed at the vent screw clamping point of the pneumatic fixture. This allows the vent screw that has been drilled on the pneumatic fixture to be blown out directly, making it convenient for the vent screw to be processed to be fed into the vent screw by the cylinder and push rod.

[0004] The air-blowing discharge setup blows out residual metal debris from the pneumatic clamp while simultaneously blowing the vent screw out of the clamp, preventing the debris from affecting the subsequent positioning and clamping of the vent screw within the clamp.

[0005] In air-blowing discharge, metal debris located in the processing area of ​​the vent screw is easily blown away to the feeding track of the vibratory feeder. The metal debris attached to the feeding track hinders the subsequent sliding feeding of the vent screw. Therefore, the inventors proposed an efficient drilling device for vent screws, which adds isolation measures in the drilling area of ​​the vent screw and the feeding track of the vibratory feeder to isolate the splashed metal debris.

[0019] See attached document Figure 1-8 This utility model provides a high-efficiency drilling device for vent screws, comprising the following structure: The first support 1 has a solenoid valve 11 fixedly installed on its rear side. The output end of the solenoid valve 11 is fixedly connected to an air blowing pipe 12 through a pipe. The bottom of the air blowing pipe 12 is fixedly connected to the top outer side of the first support 1. The upper mold 5 and the clamping cylinder 7 are fixedly installed at the top and bottom of the middle part of the first support 1, respectively. The bottom of the upper mold 5 is slidably connected to the lower mold 6. The bottom of the lower mold 6 is fixedly connected to the top output end of the clamping cylinder 7. Vibratory feeder 8, with a guide rail 81 detachably connected to the discharge side of the vibratory feeder 8, and mounting holes 83 and discharge grooves 82 respectively opened on the bottom front and rear sides of the guide rail 81. The second bracket 9 has a feeding cylinder 91 fixed on its outer side. The rear output end of the feeding cylinder 91 is connected to a push rod 92. The axial direction of the push rod 92 is kept in the same axial direction as the axial direction of the conversion hole. The push rod 92 cooperates with the discharge groove 82.

[0020] In this embodiment, a support column 2 is fixedly mounted on the top of the first support 1, a positioning seat 3 is fixedly mounted on the top of the support column 2, a drive motor 31 is fixedly mounted on the top left side of the positioning seat 3, a drilling lifting cylinder 32 is fixedly mounted on the bottom of the positioning seat 3, a slide block 4 is slidably connected to the middle of the support column 2, the top of the slide block 4 is fixedly connected to the bottom output end of the drilling lifting cylinder 32, a bushing 41 is snapped into the left end of the slide block 4, a telescopic shaft 42 is movably connected to the middle of the bushing 41, the top of the telescopic shaft 42 is fixedly connected to the bottom output end of the drive motor 31, a tool holder 43 is fixedly mounted at the bottom of the telescopic shaft 42, and a tool head 44 is snapped into the bottom of the tool holder 43.

[0021] The drilling lifting cylinder 32 changes the working height of the slide 4 below the positioning seat 3, completing the sliding treatment of the slide 4 outside the support column 2. The drive motor 31 drives the tool holder 43 to rotate through the telescopic shaft 42. The telescopic shaft 42 is assembled on the slide 4 through the bushing 41, so that the tool holder 43 and the tool head 44 can rotate in cooperation with the drive motor 31 and the telescopic shaft 42 during the lifting of the slide 4, which makes it convenient for the tool head 44 to drill the air release screw held between the upper mold 5 and the lower mold 6 through the working hole 51 of the upper mold 5.

[0022] In this embodiment, the upper mold 5 has a working hole 51 in the middle for matching the cutting head 44, and multiple guide rods 52 are fixed at the bottom of the upper mold 5. The outer side of the guide rods 52 is movably inserted into the outer side of the lower mold 6. The bottom of the upper mold 5 and the top of the lower mold 6 have clamping areas that match the shape of the venting screw. The clamping areas extend backward to match the air outlet of the air blowing pipe 12.

[0023] The design of the working hole 51 facilitates the drilling operation of the cutter head 44 on the air release screws clamped between the upper mold 5 and the lower mold 6. The guide rod 52 completes the lifting and lowering guidance of the lower mold 6 below the upper mold 5. The clamping area cooperates with the air blowing pipe 12. The clamping cylinder 7 drives the lower mold 6 to move downward. When the connection between the lower mold 6 and the upper mold 5 is released, the solenoid valve 11 and the air blowing pipe 12 cooperate to blow up the air release screws on the lower mold 6, blowing the air release screws on the lower mold 6 away, so as to avoid the air release screws staying and affecting the subsequent air release screw feeding.

[0024] In this embodiment, a stop cylinder 84 is fixedly provided at the bottom of the guide rail 81, and a clamping plate 85 is fixedly provided at the bottom output end of the stop cylinder 84. The bottom of the clamping plate 85 extends to the inner side of the bottom of the guide rail 81.

[0025] The vibratory feeder 8 feeds the venting screw that needs to be drilled into the guide rail 81. The stop cylinder 84 cooperates with the clamping plate 85 to block and release the venting screw on the guide rail 81.

[0026] In this embodiment, guide pulleys 86 are movably connected to the front and rear sides of the right end of the guide rail 81, and an isolation plate 87 is movably connected to the right end of the guide rail 81. The isolation plate 87 is disposed between the guide rail 81 and the upper mold 5. A traction rope 88 is fixedly provided on the front side of the isolation plate 87. The outer side of the traction rope 88 is movably connected to the top of the other two guide pulleys 86, and a counterweight 89 is fixedly provided at the bottom of the front end of the traction rope 88.

[0027] The design of the isolation plate 87 prevents the venting screws on the lower mold 6 from being blown onto the guide rail 81, which would affect the subsequent feeding of venting screws. The feeding cylinder 91 cooperates with the push rod 92 to push the venting screws to the bottom of the upper mold 5 through the assembly hole 83 and the discharge groove 82 of the guide rail 81, waiting for the lower mold 6 to be lifted and clamped by the clamping cylinder 7. During this process, the push rod 92 cooperates with the venting screw to push the isolation plate 87 to tilt, providing discharge guidance for the venting screws blown away on the lower mold 6.

[0028] When the feeding cylinder 91 drives the push rod 92 to reset and releases the engagement between the push rod 92 and the assembly hole 83, the counterweight 89 and the traction rope 88 work together to pull the isolation plate 87 back up through the guide pulley 86, thus completing the isolation of the part of the guide rail 81 near the upper mold 5 and the lower mold 6 from the drilling area of ​​the vent screw, and preventing splashing metal debris from affecting the normal sliding of the vent screw in the guide rail 81.

[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
