Description

Technical Field

[0001] The invention relates to the technical field of automobile copper bushing production, in particular to a drilling device with a limiting mechanism for automobile copper bushing production. Background Art

[0002] Automotive copper bushings are essential components in the automobile production process. As supporting parts for sealing and wear protection, they are currently produced in the process of copper bushings. Holes need to be drilled in the bushings according to installation requirements. Since the sizes and external structures of copper bushings are different, it is not convenient to locate different copper bushings during drilling, resulting in large errors in the hole positions, affecting the installation and use of the finished copper bushings. Therefore, a drilling device with a limiting mechanism for the production of automotive copper bushings is designed to solve the above problems. Summary of the invention

[0003] The object of the present invention is to provide a drilling device with a limiting mechanism for producing automobile copper bushings to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drilling device with a limiting mechanism for the production of automobile copper bushings, comprising a supporting mechanism and a hole-opening mechanism, the supporting mechanism comprising a supporting seat, both sides of the upper end of the supporting seat are fixedly provided with a door-type frame, the hole-opening mechanism comprises a door-type sliding frame, the door-type sliding frame is slidably arranged between the top ends of the two door-type frames, and the door-type sliding frame slides to adjust the specific hole-opening position of the entire hole-opening mechanism.

[0005] A suspension rod is slidably inserted at the center position of the top of the gate-type sliding frame, a motor is fixedly provided at the bottom end of the suspension rod, and a drill bit is connected to the power shaft of the motor. The specific position of the gate-type sliding frame is adjusted according to the hole opening position, the suspension rod slides down the gate-type sliding frame, and the drill bit is driven by the downward pressed motor to perform the hole opening operation at the corresponding position.

[0006] Several support rods are hinged on the opposite side walls of the two portal frames, and torsion springs are provided at the hinges. Two support rods in the same vertical plane form a group. The dry group of support rods constitutes a copper bushing of different sizes and shapes to be opened. The load-bearing support rods are affected by the gravity of the copper bushing and rotate downward around the hinge position, while the position of the non-load-bearing support rods does not change, which plays a limiting role to avoid the copper bushing from sliding sideways during the opening process and avoid large errors in the opening position, which affect the installation and use of the finished copper bushing.

[0007] In a further embodiment, an inverted T-shaped slide groove is provided at the top of the portal frame, a support block is fixedly provided at the bottom end of the portal sliding frame, and the bottom end surface of the support block is provided with an inverted T-shaped clamping block that can slide and engage with the inside of the inverted T-shaped slide groove. The inverted T-shaped clamping block is used to slide horizontally along the inside of the inverted T-shaped slide groove of the portal frame to prevent the portal sliding frame from tipping over or detaching from the upper end of the portal frame during the process of sliding to adjust the position, thereby ensuring that the normal operation of the entire hole opening mechanism to adjust the hole opening position is not affected.

[0008] In a further embodiment, a push rod is hinged at the bottom of the end of each support rod, and a plurality of parallel inverted T-shaped adjustment slots are provided on the upper end surface of the support seat. The end of the push rod slides and extends into the inverted T-shaped adjustment slot and is hinged with a limit slider located inside the inverted T-shaped adjustment slot. Lifting slots connected to the inside of the inverted T-shaped adjustment slot are provided on both side walls of the support seat, and a limit rod that passes through the inside of the inverted T-shaped adjustment slot is slidably inserted between the two lifting slots. The axial ends of the limit rod pass through the lifting slots on both sides of the support seat, and the outer walls of the limit rod are fixedly sleeved with limit blocks. A coupling notch that is coupled to a limit block is provided at the bottom end of the slider. Since the copper bushings have different sizes and external structures, when placed on the upper ends of several support rods, in order to ensure that the copper bushings to be opened are stably distributed upward, each of the contacted support rods is flipped around the corresponding hinged position, and the limit slider synchronously slides and adjusts its position along the inverted T-shaped adjustment groove. At the same time, the limit block on the outer wall of the limit rod is engaged with the coupling notch on the bottom end face of the limit slider to prevent the limit slider from sliding arbitrarily to adjust its position, causing the copper bushing to break away from the stable support of the support rod and fall off.

[0009] In a further embodiment, two symmetrically distributed elliptical elastic steel rings are fixedly provided at the bottom end of the outer wall of the limit rod, and the elliptical elastic steel rings are fixedly arranged on the bottom end surface of the inverted T-shaped adjustment groove. The elastic force of the elliptical elastic steel rings is utilized to lift the limit rod upward along the inside of the two lifting grooves in real time, ensuring that the limit block can be stably engaged in the engaging notch at the bottom end of the limit slider, thereby preventing the limit slider from sliding randomly and affecting the stable support of the support rod.

[0010] In a further embodiment, the limit block is a truncated cone structure, and the limit blocks at both ends of the outer wall of the limit rod are symmetrically distributed. When the copper bushing is placed on the support rod, the limit slider can be moved over the limit blocks on the outer wall of the limit rod in sequence through the push rod. At the same time, the elliptical elastic steel ring at the bottom end of the limit rod is continuously compressed and lifted, thereby realizing the rapid adjustment of the support angle of each support rod.

[0011] In a further embodiment, a guide rod is fixed between the side walls on both sides of the inverted T-shaped adjustment groove, and two limit sliders in the same vertical plane are slidably connected to the outer walls of the guide rod. The guide rod can enhance the stability of the two limit sliders in the same vertical plane when sliding to adjust their positions.

[0012] In a further embodiment, the outer wall of the support seat is provided with an adjustment mechanism that can adjust the limit rod downward inside the two lifting grooves, the adjustment mechanism includes a threaded adjustment rod, the threaded adjustment rod is rotatably inserted into the front end surface of the support seat, the threaded adjustment rod is rotatably sleeved with a crossbeam through an external thread, and pull rods are fixed at both ends of the crossbeam, and a plurality of inverted L-shaped shift blocks are vertically provided on the upper end of the pull rod, and an end of the inverted L-shaped shift block away from the pull rod is provided with a sliding inclined surface that can slidably fit with the upper end of the side wall of the end of the limit rod. The adjustment mechanism is used to adjust the limit rod downward inside the two lifting grooves, so that the limit block on the outer wall of the limit rod is disengaged from the clamping notch on the bottom end surface of the limit slider, and the torsional potential energy of the torsion spring can automatically reset the support rod so that it can be used for support again.

[0013] In a further embodiment, guide seats are fixedly provided on both side walls of the support seat, and the guide seats are provided with plugging holes for slidingly plugging with the pull rod. When the pull rod slides, it can slide along the plugging holes of the guide seats, thereby enhancing the stability of the pull rod when sliding and pulling.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention discloses a drilling device with a limiting mechanism for producing copper bushings for automobiles. Copper bushings of different sizes and shapes are placed on a supporting structure composed of a plurality of supporting rods. The load-bearing supporting rods are affected by the gravity of the copper bushings and rotate downward around the hinged positions. According to the hole opening position, the specific position of the hole opening mechanism is adjusted by sliding along the upper ends of two door-shaped frames. Subsequently, a hanging rod is slid down along the door-shaped sliding frames, and a drill is driven by a downwardly pressed motor to perform a hole opening operation at the corresponding position. When opening a hole, the position of the non-load-bearing supporting rod does not change, which plays a role of limiting, thereby avoiding the side slip of the copper bushing during the hole opening process, and avoiding large errors in the hole opening position, which would affect the installation and use of the finished copper bushing.

[0023] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiment 1

[0025] See also Figure 1-2 The present embodiment provides a drilling device with a limiting mechanism for the production of automobile copper bushings, including a supporting mechanism 1 and a hole-opening mechanism 2. The supporting mechanism 1 includes a supporting seat 11. Both sides of the upper end of the supporting seat 11 are fixedly provided with a door-shaped frame 12. The two door-shaped frames 12 are hinged with a plurality of supporting rods 14 on the opposite side walls, and a torsion spring is provided at the hinge. Two supporting rods 14 in the same vertical plane form a group. A plurality of groups of supporting rods 14 constitute copper bushings of different sizes and shapes to be opened. The load-bearing supporting rods 14 are affected by the gravity of the copper bushings and rotate downward around the hinged position, while the position of the non-load-bearing supporting rods 14 does not change, which plays a role of limiting, avoiding the copper bushing from sliding sideways during the hole-opening process, and avoiding large errors in the hole-opening position, which affects the installation and use of the finished copper bushing.

[0026] The hole-opening mechanism 2 includes a door-type sliding frame 21, which is slidably arranged between the top ends of the two door-type frames 12. The door-type sliding frame 21 is supported by the two door-type frames 12 sliding in the air. The door-type sliding frame 21 slides to adjust the specific hole-opening position of the entire hole-opening mechanism 2 to meet the hole-opening requirements.

[0027] An inverted T-shaped slot 13 is provided at the top of the portal frame 12, and a support block 24 is fixedly provided at the bottom end of the portal sliding frame 21. The bottom end surface of the support block 24 is provided with an inverted T-shaped block 25 that can slide and engage with the inside of the inverted T-shaped slot 13. The portal sliding frame 21 slides horizontally along the top end surface of the portal frame 12 by means of the support block 24, thereby enhancing the sliding stability of the portal sliding frame 21. In addition, the inverted T-shaped block 25 is used to slide horizontally along the inside of the inverted T-shaped slot 13 of the portal frame 12, thereby preventing the portal sliding frame 21 from tipping over or detaching from the upper end of the portal frame 12 during the process of sliding and adjusting its position, thereby ensuring that the normal operation of adjusting the opening position of the entire opening mechanism 2 is not affected.

[0028] A suspension rod 22 is slidably inserted into the center position of the top end of the door-type sliding frame 21, and a motor 23 is fixedly installed at the bottom end of the suspension rod 22. The power shaft of the motor 23 is connected to a drill bit. The specific position of the door-type sliding frame 21 is adjusted according to the hole opening position, and the suspension rod 22 is slid down along the door-type sliding frame 21. The drill bit is driven by the downward pressed motor 23 to perform the hole opening operation at the corresponding position.

[0029] The entire hole-opening process does not require any additional positioning structure, and can achieve stable placement of copper bushings of different sizes and shapes. During the hole-opening process, there will be no positional offset or large swing, ensuring that the entire hole-opening process is carried out stably and efficiently.

[0030] Embodiment 2

[0031] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 , further improvements were made on the basis of Example 1:

[0032] A push rod 15 is hinged at the bottom of the end of each support rod 14, and a plurality of parallel inverted T-shaped adjustment grooves are provided on the upper end surface of the support seat 11. The end of the push rod 15 slides and extends into the inside of the inverted T-shaped adjustment groove and is hinged with a limit slider 16 located inside the inverted T-shaped adjustment groove. The load-bearing support rod 14 is pressed down by the copper bushing to rotate and swing downward, and the limit slider 16 can be slid and adjusted horizontally along the inside of the inverted T-shaped adjustment groove through the push rod 15 to compensate for the height difference when the support rod 14 flips around the hinge position.

[0033] If the support rod 14 is continuously pressed down by the weight of the copper bushing, the copper bushing will be separated from the support rod 14 and fall onto the support seat 11, and the purpose of stable support of the copper bushing will not be achieved. Therefore, lifting grooves connected to the inside of the inverted T-shaped adjustment groove are provided on both side walls of the support seat 11, and a limit rod 18 penetrating the inside of the inverted T-shaped adjustment groove is slidably inserted between the two lifting grooves. The axial ends of the limit rod 18 penetrate the lifting grooves on both sides of the support seat 11, and the two ends of the outer wall of the limit rod 18 are fixedly sleeved with limit blocks 110. The bottom end of the limit slider 16 is provided with a limit block 110 that is connected to the limit block 110. The snap-fitting notch, since the copper bushings have different sizes and external structures, when placed on the upper ends of several support rods 14, in order to ensure that the copper bushings to be opened are stably distributed upward, each of the contacted support rods 14 is flipped around the corresponding hinged position, and the limit slider 16 slides synchronously along the inverted T-shaped adjustment groove to adjust the position. At the same time, the limit block 110 on the outer wall of the limit rod 18 is snapped with the snap-fitting notch on the bottom end face of the limit slider 16 to prevent the limit slider 16 from sliding arbitrarily to adjust the position, causing the copper bushing to break away from the stable support of the support rod 14 and fall off.

[0034] By providing a plurality of independently rotatable support rods 14, each support rod 14 rotates around a hinge position, so as to provide stable support for the copper bushing and ensure that the copper bushing to be opened is stably distributed upward.

[0035] In order to ensure that the limit block 110 on the outer wall of the limit rod 18 can be engaged with the limit slider 16 in real time, two symmetrically distributed elliptical elastic steel rings 19 are fixedly provided at the bottom end of the outer wall of the limit rod 18. The elliptical elastic steel ring 19 is fixedly arranged on the bottom end surface of the inverted T-shaped adjustment groove. The elastic force of the elliptical elastic steel ring 19 is utilized to push the limit rod 18 upward along the inside of the two lifting grooves in real time, ensuring that the limit block 110 can be stably engaged in the engaging notch at the bottom end of the limit slider 16, preventing the limit slider 16 from sliding arbitrarily and affecting the stable support of the support rod 14.

[0036] By making the limit block 110 a truncated cone structure, the limit blocks 110 at both ends of the outer wall of the limit rod 18 are symmetrically distributed. After the copper bushing is placed on the support rod 14, the limit slider 16 can be moved over the limit blocks 110 on the outer wall of the limit rod 18 in sequence through the push rod 15. At the same time, the elliptical elastic steel ring 19 at the bottom end of the limit rod 18 is continuously compressed and lifted, thereby realizing the rapid adjustment operation of the support angle of each support rod 14.

[0037] A guide rod 17 is fixed between the side walls on both sides of the inverted T-shaped adjustment groove, and the two limit sliders 16 in the same vertical plane are slidably connected to the outer wall of the guide rod 17. The guide rod 17 can enhance the stability of the two limit sliders 16 in the same vertical plane when sliding to adjust their positions.

[0038] Embodiment 3

[0039] See also Figure 1 and Figure 5 , further improvements were made on the basis of Example 2:

[0040] After the copper bushing is drilled, the copper bushing is removed from the support rod 14, and all the rotating support rods 14 need to be reset. An adjustment mechanism 3 is provided on the outer wall of the support seat 11, which can adjust the limit rod 18 downward inside the two lifting grooves. The adjustment mechanism 3 is used to adjust the limit rod 18 downward inside the two lifting grooves, so that the limit block 110 on the outer wall of the limit rod 18 is disengaged from the clamping notch on the bottom end surface of the limit slider 16. The torsional potential energy of the torsion spring can automatically reset the support rod 14 so that it can be used for support again.

[0041] The adjustment mechanism 3 includes a threaded adjustment rod 31, which is rotatably inserted into the front end surface of the support seat 11. The threaded adjustment rod 31 is rotatably sleeved with a cross beam 32 through an external thread. Pull rods 33 are fixed at both ends of the cross beam 32. A plurality of inverted L-shaped shift blocks 35 are vertically provided at the upper end of the pull rod 33, and the end of the inverted L-shaped shift block 35 away from the pull rod 33 is provided with a sliding inclined surface that can slide and fit with the upper end of the side wall of the end of the limit rod 18. Rotating the threaded adjustment rod 31 by hand can drive the cross beam 32 to adjust its position along the axial direction of the threaded adjustment rod 31, and the inverted L-shaped shift blocks 35 on the pull rods 33 on both sides adjust their positions synchronously with the cross beam 32.

[0042] When the support rod 14 needs to be reset, the pull rod 33 is slid horizontally, driving the sliding inclined surface of the inverted L-shaped shift block 35 to slide along the end of the limit rod 18. As the inverted L-shaped shift block 35 is continuously adjusted horizontally, the sliding inclined surface can be used to press the limit rod 18 down along the inside of the lifting groove, so that the limit block 110 on the outer wall of the limit rod 18 is disengaged from the clamping notch on the bottom end surface of the limit slider 16. The torsional potential energy of the torsion spring can be used to automatically reset the support rod 14.

[0043] Guide seats 34 are fixedly provided on both side walls of the support seat 11. The guide seats 34 are provided with insertion holes for slidingly inserting with the pull rod 33. When the pull rod 33 slides, it can slide along the insertion holes of the guide seats 34, thereby enhancing the stability of the pull rod 33 when sliding and pulling.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
