Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wheel hub production, and particularly relates to a boat plough wheel hub air valve hole processing equipment. BACKGROUND

[0002] The boat plough wheel hub is a key component of the transmission system of the boat plough, and the air valve hole is a key structure on the wheel hub and is used for mounting an air valve nozzle to realize the inflation and sealing functions of the tire. When the air valve hole is opened, two ways of manual drilling and drilling by a drilling machine are generally adopted. The manual drilling has low working efficiency, the drilled air valve hole is not standard, and defective products are prone to be produced. The drilling by the drilling machine improves the efficiency to a certain extent, but it is inconvenient to clamp the wheel hub, mass production cannot be realized, and the drilling precision is affected by the clamping stability.

[0003] A wheel hub air valve hole processing equipment is disclosed in a Chinese patent with the authorization announcement No. CN114654274B, which comprises a first support frame, the upper end of the first support frame is provided with a clamping mechanism, one side of the first support frame is fixedly connected with a first support plate, the upper end of the first support plate is vertically fixedly connected with a second support frame, the second support frame is slidably connected with a second sliding block, and the front side of the second sliding block is fixedly connected with a second support plate. The splashing of debris is avoided, and the drill bit can be cooled by increasing the air flow on the surface of the drill bit.

[0004] Since the wheel hub is circular, the air valve hole is generally inclined and opened on the cylindrical surface of the wheel hub. When the existing wheel hub air valve hole processing equipment is drilling, the drill bit contacts the wheel hub at a pre-set angle and drills a hole, but the drill bit may jump when it first contacts the wheel hub, which will cause scratches on the surface of the wheel hub and also cause deviation in the drilling, thereby making the wheel hub a defective product or a waste product. SUMMARY

[0005] The purpose of the present application is to provide a boat plough wheel hub air valve hole processing equipment, which aims to solve the following problems existing in the prior art air valve hole processing equipment: the drill bit may jump when it first contacts the wheel hub, which will not only cause scratches on the surface of the wheel hub, but also cause deviation in the drilling.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a boat plough wheel hub air valve hole processing equipment, comprising a base, a tool clamp is fixedly installed on the top of the base, and a stamping and punching mechanism is fixedly installed on the tool clamp. The stamping and punching mechanism comprises a box body, a transmission assembly is slidably installed at the top inside the box body, a striking assembly is slidably installed at the bottom inside the box body, a punching piece is installed at the bottom of the inner wall of one end of the box body, and a second driving assembly is installed at the top inside the box body, which is used to drive the transmission assembly to move away from the punching piece.

[0009] The beneficial effects of the present application are: by setting the transmission assembly, the second driving assembly and the impact assembly, the second driving assembly drives the transmission assembly and the impact assembly to move away from the direction of the punching member, and the driving elastic element is stretched. When the transmission assembly and the impact assembly move to the fixed block, the clamping block starts to descend along the axis direction of the limiting column under the action of its own inclined surface and the fixed block. At this time, the pushing block is no longer in contact with the clamping block, so that the impact block moves quickly to the punching member under the action of the driving elastic element, and the punching member is knocked out of the box body, and the air hole of the hub is impacted, so that a limiting guide hole is punched out of the air hole of the hub. Therefore, when drilling the air hole of the hub, the drill bit can be drilled under the action of the limiting guide hole, avoiding the drill bit from jumping when it first contacts the hub during drilling, which causes scratches on the surface of the hub and deviation during drilling.

[0013] The punching part comprises a punching column extending along the sliding direction of the transmission assembly. One end of the punching column is slidable along the axis direction of the punching column and extends out of the box body, and the other end is fixedly installed with an abutting block. A restoring member is fixedly connected between the abutting block and the inner wall of the box body, and the restoring member is sleeved on the outer wall of the punching column.

[0014] An automatic telescopic rod is fixedly installed on the inner wall of the end of the box body where the punching part is installed, and the telescopic direction of the automatic telescopic rod is consistent with the axis direction of the punching column. A travel switch is fixedly installed on the bottom of the side close to the punching part, and the travel switch is used to control the telescopic action of the telescopic end of the automatic telescopic rod.

[0015] The effect is that the automatic telescopic rod can push the impact assembly to move a distance away from the punching part after the device is completed, and the movement of the impact assembly towards the punching part is limited, so that the punching part and the transmission assembly are reset.

[0016] The tool clamp comprises a clamping table fixedly installed on the base, and a mounting plate fixedly installed at the top edge of the clamping table and perpendicular to the top surface of the clamping table. An installation groove is formed in the mounting plate, and the stamping and punching mechanism is fixedly installed in the installation groove. The movement direction of the transmission assembly is perpendicular to the mounting plate and horizontally points to the center of the clamping table. A bottom plate is installed on the top of the clamping table, and a hinge shaft is arranged on the side of the bottom plate away from the mounting plate. The axis of the hinge shaft is parallel to the mounting plate and extends in the horizontal direction. The bottom plate is hinged to the clamping table through the hinge shaft, and the clamping table is internally provided with a first driving assembly for driving the rotation of the bottom plate.

[0017] The first driving assembly comprises a support shaft, a transmission screw, a driving motor and a transmission block fixedly installed on one side of the outer wall of the clamping table. The axis directions of the support shaft and the transmission screw extend along the movement direction of the transmission assembly. The transmission block is sleeved on the outer walls of the support shaft and the transmission screw, wherein the transmission block is slidingly connected with the support shaft and threadedly connected with the transmission screw. A hinge seat is fixedly installed on the bottom of the bottom plate, and a connecting rod is connected between the transmission block and the hinge seat, and the two ends of the connecting rod are hinged to the transmission block and the hinge seat, respectively.

[0018] The effect is that the first driving assembly is arranged, the bottom plate, the fixed plate and the clamping assembly can be driven to rotate around the hinge shaft, the inclination angle of the hub can be adjusted, the position of the hub where the valve hole is drilled is on the axis of the punching column, the axis of the valve hole coincides with the axis of the punching column, the guide limiting hole can be punched in the valve hole of the hub in advance by the punching mechanism, the drill bit is limited and guided during drilling, the drill bit is prevented from jumping when it first contacts the hub during drilling, and the surface of the hub is prevented from being scratched and the drilling deviation is prevented.

[0023] Compared with the prior art, the beneficial effects of the present application are: By setting the transmission assembly, the second driving assembly and the impact assembly, the second driving assembly drives the transmission assembly and the impact assembly to move away from the punching member, and stretches the driving elastic member. When the transmission assembly and the impact assembly move to the fixed stopper, the clamping block starts to descend along the axis direction of the limiting column under the action of the self inclined surface and the fixed stopper. At this time, the pushing block is no longer in contact with the clamping block, so that the impact block moves quickly to the punching member under the action of the driving elastic member, and the punching member is knocked out of the box, and the valve hole of the wheel hub is impacted, so that the valve hole of the wheel hub is punched out of a limiting guide hole. Therefore, when drilling the valve hole of the wheel hub, the drill bit can be drilled under the action of the limiting guide hole, avoiding the jump of the drill bit when it first contacts the wheel hub, causing scratches on the surface of the wheel hub and deviation during drilling.

The transmission screw 272, through its threaded connection with the transmission slider 274, causes it to slide along the axis of the support shaft 271. At this time, as the transmission slider 274 moves, it drives the base plate 22, the fixing plate 23, the clamping assembly 24, and the hub to rotate around the hinge shaft 221 via the connecting rod 275, thereby changing the hub from a horizontal position to an inclined position.

[0038] refer to Figures 8-10 As shown, the punching and drilling mechanism 3 includes a housing 31, a partition 32, a transmission assembly 33, a second drive assembly 34, an impact assembly 35, a punching component 36, a reset component 37, an automatic telescopic rod 38, and a fixed stop block 39.

[0039] The housing 31 is fixedly installed in the mounting slot 26, with its length direction perpendicular to the mounting plate 25 and its horizontal direction pointing towards the center of the clamping table 21.

[0040] The partition 32 is fixedly installed inside the box 31 and is parallel to the bottom surface of the box 31. The partition 32 divides the inside of the box 31 into upper and lower parts. A connecting groove 321 extending along the length of the box 31 is opened at the middle of the top of the partition 32. Guide rails 322 extending along the length of the box 31 are fixedly installed at the top and bottom of the partition 32.

[0043] The impact assembly 35 includes a connecting plate 351, with an impact block 352 fixedly mounted on the bottom of the connecting plate 351 and a limiting post 355 fixedly mounted on the top of the connecting plate 351. A locking block 357 is slidably sleeved on the top of the limiting post 355. The top of the locking block 357 has an inclined surface that slopes away from the punched part 36. A reset elastic element 356 is fixedly connected between the bottom of the locking block 357 and the top of the connecting plate 351, and the reset elastic element 356 is sleeved on the outer wall of the limiting post 355. A driving elastic element 353 is fixedly connected between the inner wall of the end of the housing 31 where the punched part 36 is mounted and the connecting plate 351.

A lower track slider 354 is fixedly mounted on the end of the connecting plate 351 near the partition 32, and the lower track slider 354 is slidably sleeved on the guide rail 322 at the bottom of the partition 32.

[0044] The punched part 36 is installed inside the housing 31 near one end of the tooling fixture 2. It includes a punched post 361 whose axis extends along the sliding direction of the transmission assembly 33. One end of the punched post 361 near the tooling fixture 2 slides out of the housing 31 along its axis. The other end of the punched post 361 is fixedly installed with an abutment block 362.

[0046] The automatic telescopic rod 38 is fixedly installed on the inner wall of the end of the housing 31 where the punched part 36 is installed, and is located on the same horizontal plane as the punched part 36. There can be one or more automatic telescopic rods 38. The telescopic direction of the automatic telescopic rod 38 is the same as the axial direction of the punched column 361. A limit switch 381 is fixedly installed on the bottom side of the partition 32 near the punched part 36. The limit switch 381 is used to control the telescopic end of the automatic telescopic rod 38.

[0047] The fixed stop 39 is fixedly installed at the end of the connecting slide 321 away from the punched part 36 and flush with the inclined surface of the locking block 357.

[0048] The implementation principle of this invention is as follows: When drilling a wheel hub, it is placed on the clamping table 21 and clamped and fixed. Then, the first driving assembly 27 drives the base plate 22, the fixing plate 23, the clamping assembly 24 and the wheel hub to rotate around the hinge shaft 221, thereby changing the wheel hub from a horizontal position to an inclined position. This allows the tilt angle of the wheel hub to be adjusted so that the axis of the contour valve hole coincides with the axis of the punching post 361.

[0049] The punching motor 342 is started, causing the drive screw 343 to rotate. The drive screw 343, through a threaded connection with the transmission plate 331, drives the transmission plate 331 away from the punching part 36 along the axial direction of the drive screw 343. At this time, the transmission plate 331, through the cooperation of the push block 332 and the locking block 357, drives the connecting plate 351 and the impact block 352 to move synchronously away from the punching part 36, and stretches the drive elastic element 353. Simultaneously, the connecting plate 351 moves away from the limit switch 381, and the limit switch 381 cannot control the automatic telescopic rod 38 to retract its telescopic section after detecting the connecting plate 351. When the inclined surface of the locking block 357 moves to contact the fixed block 39, the locking block 357 moves downward along the axial direction of the limit post 355 under the action of the fixed block 39, and compresses the reset elastic element 356. At this time, the locking block 357 gradually disengages from the push block 332. Once the locking block 357 is no longer in contact with the pushing block 332, the connecting plate 351 and the impact block 352, under the elastic force of the driving elastic element 353, quickly move towards the punched part 36 and impact it. At this time, the punched post 361 is knocked out of the housing 31 and impacts the valve hole of the wheel hub, causing a guide limiting hole to be punched out on the wheel hub. Then, the wheel hub is adjusted from an inclined position to a vertical position, with the guide limiting hole facing vertically upwards. At this time, the drilling mechanism 5 drills along the guide limiting hole.

[0050] After the impact block 352 impacts the punched part 36, the locking block 357 resets under the action of the reset elastic element 356. The connecting plate 351 moves to the limit switch 381. At this time, after the limit switch 381 detects the connecting plate 351, it activates the automatic telescopic rod 38, causing its telescopic end to push out and push the connecting plate 351 and the impact block 352 to move a distance away from the punched part 36. At this time, the punching column 361 begins to retract into the housing 31 for reset under the action of the reset element 37. At the same time, the punching motor 342 is controlled to flip, causing it to drive the drive screw 343 to rotate in the opposite direction. At this time, the drive screw 343 drives the transmission plate 331 to move in the opposite direction, so that the transmission plate 331 and the push stop 332 gradually approach the connecting plate 351. When the push stop 332 contacts the locking block 357, the locking block 357 moves downward along the axis of the limit post 355 under the action of the push stop 332, so that the push stop 332 can pass over the locking block 357.

[0051] Although embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
