Description

Technical Field

[0001] The present invention relates to the technical field of drilling of automotive panel parts, and particularly to a fixed-aperture drilling device based on automotive panel parts. Background Art

[0002] Automotive panel parts refer to the surfaces or internal parts of spatial shapes made of metal sheets that cover the engine, chassis, and form the cab and body. They can be divided into three categories: external panel parts, internal panel parts, and skeleton panel parts according to functions and positions. They have different characteristics from general stamping parts in aspects such as process design, die processing, equipment selection, and quality control (dimensional tolerance, shape accuracy, part stiffness, surface quality).

[0003] When drilling automotive panel parts, a drill chuck is usually used to clamp the drill bit. Since the existing drill chuck only clamps a small section of the drill bit, and due to the relatively high surface hardness of the existing automotive panel parts, it is difficult for the existing drill chuck to clamp the drill bit tightly, and the drill bit is prone to sliding or shaking in the drill chuck.

[0004] When processing automotive panel parts, due to the shaking of the drill bit, the diameter of the drilled hole on the automotive panel part cannot be directly determined, resulting in deviations. Summary of the Invention

[0005] Aiming at the above problems existing in the prior art, the technical problem to be solved by the present invention is that when processing automotive panel parts, due to the shaking of the drill bit, the diameter of the drilled hole on the automotive panel part cannot be directly determined, resulting in deviations.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: A fixed-aperture drilling device based on automotive panel parts, comprising:

[0007] A drilling mechanism, including a clamping assembly and a power member; the clamping assembly includes a drill chuck sleeve, an upper clamping member, a lower clamping member, and a transmission member; the upper clamping member and the lower clamping member are respectively installed on the upper and lower sides of the drill chuck sleeve; the upper clamping member can clamp the tail end of the drill bit in the drill chuck sleeve, and the lower clamping member can clamp the middle part of the drill bit in the drill chuck sleeve; the transmission member can drive the upper clamping member and the lower clamping member to act; the power member can drive the drill chuck sleeve to rotate;

[0008] A feeding mechanism, driving the drilling mechanism to feed; and

[0009] A bracket, supporting the feeding mechanism.

[0010] In the present invention, the drill bit is placed in the drill chuck, and then the transmission member is controlled to act. The transmission member drives the upper clamping member and the lower clamping member to act, so that the tail end and the middle part of the drill bit are clamped. By clamping the drill bit at two places, the stability of the drill bit is increased, thereby effectively preventing the drill bit from shaking during the drilling operation, so that the diameter of the hole drilled in the automotive panel can be determined without deviation. Then, the bracket holds the drilling mechanism above the automotive panel, the power member is controlled to act, the power member drives the drill chuck to rotate, thereby driving the drill bit clamped in the drill chuck to rotate, and then the feeding mechanism is controlled to act, so that the drill bit drills the automotive panel.

[0011] Preferably, the upper clamping member and the lower clamping member have the same structure and are symmetrically arranged. A plurality of the upper clamping members are annularly arrayed with the axis of the drill chuck as the center. The upper clamping member includes a slider, a resisting rod and a gear. The slider is slidably mounted on the drill chuck. One end of the slider away from the drill bit is fixedly connected to one end of the resisting rod. The gear is rotatably mounted on the drill chuck. A spiral groove is provided on one side of the gear. The other end of the resisting rod extends into the spiral groove, and the other end of the resisting rod is slidably connected to the spiral groove. The transmission member drives the gear to rotate. The gear drives the resisting rod to slide through the spiral groove. The resisting rod drives the slider to slide, so that one end of the resisting rod close to the drill bit presses the drill bit tightly.

[0012] Preferably, the slider has a certain included angle towards the inside of the drill chuck. The slider on the upper clamping member slides obliquely downward, and the slider on the lower clamping member slides obliquely upward, so that the drill bit can be clamped from different directions.

[0013] Preferably, anti-slip lines are provided at one end of the slider close to the drill bit. Thereby, the relative sliding between the drill bit and the slider can be effectively prevented.

[0014] Preferably, a clamping groove matching with the tail end of the drill bit is provided in the drill chuck. By clamping the tail end of the drill bit into the clamping groove, the stability of the drill bit can be further improved.

[0015] Preferably, the transmission member includes a sliding sleeve, a rack and a driving unit. Sliding sleeves are respectively sleeved at both ends of the drill chuck. Both of the sliding sleeves are slidably connected to the drill chuck. A rack is installed in the long direction of the inner side of the sliding sleeve, and the rack corresponds to and meshes with the gear one by one. The driving unit drives the two sliding sleeves to slide relatively. The driving unit drives the two sliding sleeves to slide relatively, thereby driving the gears on the corresponding upper clamping member and lower clamping member to rotate, so that the upper clamping member and the lower clamping member clamp the drill bit.

[0016] Preferably, the driving unit includes a threaded sleeve and a limiting ring; the threaded sleeve is sleeved outside the two sliding sleeves, both ends of the threaded sleeve are threadedly connected to the sliding sleeves, and the thread directions on the two sliding sleeves are opposite; the limiting ring is fixedly sleeved on the drill chuck, a limiting groove is formed inside the threaded sleeve, the outer edge of the limiting ring extends into the limiting groove, and the threaded sleeve is rotatably connected to the limiting ring. Under the action of the limiting ring and the limiting groove, the threaded sleeve rotates around its axis, and the threaded sleeve drives the sliding sleeves threadedly connected thereto to move. The sliding sleeves slide linearly along the axial direction, thereby driving the upper clamping member and the lower clamping member to clamp the drill bit.

[0017] Preferably, the feeding mechanism includes a fixing member and a telescopic member. One end of the telescopic member is fixedly connected to the drilling mechanism, the other end of the telescopic member is fixedly installed on the fixing member, and the telescopic direction of the telescopic member is the same as the axial direction of the drill bit; the fixing member is fixedly installed on the bracket. The automotive panel is fixed on the bracket, the drilling mechanism is turned on, and the telescopic member is controlled to feed, so as to drive the drilling mechanism to drill the automotive panel.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] In the present invention, the drill bit is placed in the drill chuck, and then the transmission member is controlled to act. The transmission member drives the upper clamping member and the lower clamping member to act, so that the tail end and the middle part of the drill bit are clamped. By clamping the drill bit at two places, the stability of the drill bit is increased, thereby effectively preventing the drill bit from shaking during the drilling operation, so that the diameter of the hole drilled in the automotive panel can be determined without deviation.

[0028] See Figure 1 - Figure 2, the embodiments provided by the present invention: a fixed-aperture drilling device for automotive panel parts, comprising: a drilling mechanism 1, including a clamping assembly and a power member; the clamping assembly includes a drill chuck 11, an upper clamping member 12, a lower clamping member 13 and a transmission member 14; the upper clamping member 12 and the lower clamping member 13 are respectively installed on the upper and lower sides of the drill chuck 11; the upper clamping member 12 can clamp the tail end of the drill bit 4 in the drill chuck 11, and the lower clamping member 13 can clamp the middle part of the drill bit 4 in the drill chuck 11; the transmission member 14 can drive the upper clamping member 12 and the lower clamping member 13 to act; the power member can drive the drill chuck 11 to rotate, specifically, the power member can be a motor; a feeding mechanism 2, driving the drilling mechanism 1 to feed; and a bracket 3, supporting the feeding mechanism 2. Further, a clamping groove 111 matching with the tail end of the drill bit 4 is provided in the drill chuck 11. Inserting the tail end of the drill bit 4 into the clamping groove 111 can further improve the stability of the drill bit 4.

[0029] During specific implementation, place the drill bit 4 in the drill chuck 11, then control the transmission member 14 to act. The transmission member 14 drives the upper clamping member 12 and the lower clamping member 13 to act, so that the tail end and the middle part of the drill bit 4 are clamped. By clamping the drill bit 4 at two places, the stability of the drill bit 4 can be increased, thereby effectively preventing the drill bit 4 from shaking during the drilling operation, so that the diameter of the hole drilled on the automotive panel part can be determined without deviation; then the bracket 3 supports the drilling mechanism 1 above the automotive panel part, control the power member to act, the power member drives the drill chuck 11 to rotate, so as to drive the drill bit 4 clamped in the drill chuck 11 to rotate, and then control the feeding mechanism 2 to act, so that the drill bit 4 drills the automotive panel part.

[0030] See Figure 1 - Figure 3, in other embodiments, the upper clamping member 12 and the lower clamping member 13 have the same structure and are symmetrically arranged. A plurality of upper clamping members 12 are annularly arrayed with the axis of the drill chuck 11 as the center. The upper clamping member 12 includes a slider 121, a resisting rod 122, and a gear 123. The slider 121 is slidably mounted on the drill chuck 11. One end of the slider 121 away from the drill bit 4 is fixedly connected to one end of the resisting rod 122. The gear 123 is rotatably mounted on the drill chuck 11. A spiral groove 22 is provided on one side of the gear 123. The other end of the resisting rod 122 extends into the spiral groove 22, and the other end of the resisting rod 122 is slidably connected to the spiral groove 22. Further, an anti-slip pattern is provided at one end of the slider 121 close to the drill bit 4. Thereby, relative sliding between the drill bit 4 and the slider 121 can be effectively prevented. Further, the slider 121 has a certain angle towards the inside of the drill chuck 11. Specifically in implementation, the slider 121 on the upper clamping member 12 slides obliquely downward, and the slider 121 on the lower clamping member 13 slides obliquely upward, so that the drill bit 4 can be clamped from different orientations. Specifically in implementation, the transmission member 14 drives the gear 123 to rotate. The gear 123 drives the resisting rod 122 to slide through the spiral groove 22, and the resisting rod 122 drives the slider 121 to slide, so that one end of the resisting rod 122 close to the drill bit 4 presses against the drill bit 4 tightly.

[0031] See Figure 1 - Figure 3 , in other embodiments, the transmission member 14 includes a sliding sleeve 141, a rack 142, and a driving unit. The two ends of the drill chuck 11 are respectively sleeved with a sliding sleeve 141, and both sliding sleeves 141 are slidably connected to the drill chuck 11. A rack 142 is installed in the longitudinal direction inside the sliding sleeve 141, and the rack 142 corresponds to and meshes with the gear 123 one by one. The driving unit drives the two sliding sleeves 141 to slide relatively. Specifically in implementation, the driving unit acts, and the driving unit drives the two sliding sleeves 141 to slide relatively, so as to drive the gears 123 on the corresponding upper clamping member 12 and lower clamping member 13 to rotate, thereby clamping the drill bit 4 by the upper clamping member 12 and the lower clamping member 13.

[0032] See Figure 1 - Figure 3 , in other embodiments, the driving unit includes a threaded sleeve 143 and a limiting ring 144. The threaded sleeve 143 is sleeved outside the two sliding sleeves 141. The two ends of the threaded sleeve 143 are threadedly connected to the sliding sleeves 141, and the thread directions of the two sliding sleeves 141 are opposite. The limiting ring 144 is fixedly sleeved on the drill chuck 11. A limiting groove 145 is provided inside the threaded sleeve 143. The outer edge of the limiting ring 144 extends into the limiting groove 145, and the threaded sleeve 143 is rotatably connected to the limiting ring 144. Specifically in implementation, rotate the threaded sleeve 143. Under the action of the limiting ring 144 and the limiting groove 145, the threaded sleeve 143 rotates around its axis. The threaded sleeve 143 drives the sliding sleeve 141 connected to it by thread to act, and the sliding sleeve 141 linearly slides along the axis direction, thereby driving the upper clamping member 12 and the lower clamping member 13 to clamp the drill bit 4.

[0033] See Figure 1 Figure 1 , in another embodiment, the feeding mechanism 2 includes a fixing member 21 and a telescopic member 22. One end of the telescopic member 22 is fixedly connected to the drilling mechanism 1, and the other end of the telescopic member 22 is fixedly installed on the fixing member 21, and the telescopic direction of the telescopic member 22 is the same as the axis direction of the drill bit 4; the fixing member 21 is fixedly installed on the bracket 3. Specifically, the telescopic member 22 can be a hydraulic cylinder or other structures that drive the feeding of the drilling mechanism 1. Fix the automotive panel on the bracket 3, turn on the drilling mechanism 1, and control the telescopic member 22 to feed, so as to drive the drilling mechanism 1 to drill the automotive panel.
