Therefore, the function of a hinge on an automobile is to support the car door, firmly hang the car door on the vehicle body, and allow the car door to move.

[0003] In the prior art, a patent document with the publication number CN116422972B discloses an auxiliary device for processing hinge profiles of an automobile, including a bottom plate. In the middle of the upper end of the bottom plate, there is an L-shaped bracket one for support. A cutting groove one penetrating through its side wall is provided in the upper part of the L-shaped bracket one. A profile plate is placed on the upper part of the L-shaped bracket one.

An extrusion block one for horizontally extruding and fixing the profile plate is provided at the output end of the hydraulic cylinder. By setting structures such as a baffle and a water bag, the water bag and the clear water in it will push the separation mechanism and the conveying mechanism to move to the right when the extrusion block two moves upward, thereby dragging the profile plate to move the same distance each time, enabling the device to perform multiple operations within a unit time, improving the time utilization rate, and further improving the work efficiency. However, the above device has the following technical problems when in use: 1.

It is not convenient to reduce the sanding dead angles during the sanding of hinge fittings through a multi-directional synchronous sanding structure; Based on this, the present invention provides an auxiliary device for processing automotive hinge profiles to solve the problems raised in the above background art. Summary of the Invention

[0004] In view of the technical problems existing in the prior art, the present invention provides an auxiliary device for processing automotive hinge profiles to solve the problems that the existing device is not convenient to automatically complete the punching and forming of hinge profiles, the automatic blanking of hinge fittings after forming, the automatic suction of hinge fittings after blanking, and the multi-directional and all-round sanding and grinding operations of hinge fittings after suction in an automated assembly line manner, and is not convenient to reduce the sanding dead angles during the sanding of hinge fittings through a multi-directional synchronous sanding structure.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: An auxiliary device for processing automobile hinge profiles, comprising a frame, on which a double-axis drive module, a stamping component, a feeding rack and a sanding cylinder are respectively installed. A movable table capable of moving in two axes is drivingly installed on the double-axis drive module. A two-way vibration module is installed on the movable table. A vertical vibration frame capable of vibrating synchronously in two directions is connected to the two-way vibration module. A negative pressure shaft tube is rotatably installed on the vertical vibration frame. The bottom end of the negative pressure shaft tube is communicated with a positioning suction cup. A negative pressure generating module is arranged in the negative pressure shaft tube. A wire releasing mechanism is installed on the feeding rack. A hinge profile is unwound on the wire releasing mechanism. A reciprocating drive module is arranged on the feeding rack. Two stress frames capable of reciprocating movement are drivingly connected to the reciprocating drive module. A rotatable sanding roller and two symmetrically arranged clamping rollers are rotatably connected between the inner surfaces of each stress frame.

[0006] On the basis of the above technical solution, the present invention can be further improved as follows.

[0007] Further, the stamping component includes a lower die base arranged on one side of the feeding rack. The lower die base is fixedly connected to the frame. A linear drive module is installed on the frame. A stamping table is drivingly connected to the linear drive module. An upper die is arranged below the stamping table. A stamping push rod is installed between the stamping table and the upper die. A cutting knife is fixedly installed on the bottom surface of the upper die.

[0008] The beneficial effect of adopting the above further solution is that when the lower die base is attached to the upper die, a forming die cavity for forming the hinge profile is formed. After the forming die cavity is formed, on the one hand, the intercepted profile to be processed on the hinge profile is completed, and on the other hand, the stamping and forming operation of the intercepted profile on the hinge profile can be completed.

[0009] Further, the two-way vibration module includes a horizontal vibration frame. A group of first elastic limit members are installed between the horizontal vibration frame and the movable table. A motor is installed on the movable table. A transverse convex block is fixedly installed at the output shaft end of the motor. A first guide wheel is rotatably installed on the horizontal vibration frame. The first guide wheel is in contact with the transverse convex block. A fixed shaft is rotatably installed on the horizontal vibration frame. The output shaft end of the motor is drivingly connected to an elastic tension belt. The fixed shaft is drivingly connected to the elastic tension belt. A group of second elastic limit members are installed between the horizontal vibration frame and the vertical vibration frame. A straight shaft is rotatably installed on the horizontal vibration frame. The straight shaft is driven by the fixed shaft. A vertical convex block is installed on the straight shaft. A second guide wheel is rotatably installed on the vertical vibration frame. The second guide wheel is drivingly connected to the vertical convex block. The negative pressure shaft tube is driven by the fixed shaft.

[0010] The beneficial effects of adopting the above further solution are as follows: after the intercepted profile is punched and formed on the hinge profile, the formed hinge fitting remains on the lower die base. Subsequently, through the position setting of the stamping table by the linear drive module, the stamping table is moved out from directly above the lower die base. After the stamping table is moved out from directly above the lower die base, under the driving action of the dual-axis drive module, the negative pressure shaft tube and the positioning suction cup move to directly above the formed hinge fitting. When the dual-axis drive module drives the moving table to move, the motor remains stationary, thus facilitating the precise positioning of the negative pressure shaft tube and the positioning suction cup relative to the formed hinge fitting. After the negative pressure shaft tube is precisely positioned relative to the formed hinge fitting, the bottom surface of the positioning suction cup is closely attached to the formed hinge fitting, and negative pressure is generated inside the positioning suction cup, thereby realizing the negative pressure suction of the formed hinge fitting on the lower die base. After the formed hinge fitting is completely sucked by negative pressure, under the driving of the dual-axis drive module, the formed hinge fitting moves to a specified depth inside the sanding cylinder. Furthermore, a bevel gear is installed on both the straight shaft and the fixed shaft, and the two bevel gears are meshed with each other. An internally fixed connecting groove with an open bottom end is formed inside the fixed shaft. A sliding section is provided on the negative pressure shaft tube, and the sliding section is slidably connected to the connecting groove. The cross-sections of the sliding section and the connecting groove are both regular polygons.

[0011] The beneficial effects of adopting the above further solution are as follows: when the sanding cylinder is in use, a sufficient amount of polishing sand is stored inside the sanding cylinder, and the polishing sand maintains a set particle fineness. After the formed hinge fitting penetrates to a specified depth inside the sanding cylinder, the motor operates and outputs a rotational speed in a set state. After the motor outputs the rotational speed, on the one hand, it causes the formed hinge fitting to rotate at a set speed inside the sanding cylinder, and on the other hand, it causes the formed hinge fitting to vibrate in the axial and longitudinal directions synchronously during the rotation process. By the rotation and bidirectional vibration of the formed hinge fitting inside the sanding cylinder, the angle of the sand acting on the formed hinge fitting inside the sanding cylinder is changed reciprocally, thereby effectively improving the sanding efficiency and sanding effect of the formed hinge fitting after punching. Moreover, through the above sanding structure setting of the formed hinge fitting, the sanding dead angle of the formed hinge fitting can be effectively reduced. Both the first elastic limiting member and the second elastic limiting member include a T-shaped limiting rod, and a limiting spring is sleeved on the T-shaped limiting rod.

[0012] Furthermore, the negative pressure generating module includes a negative pressure pump installed on the moving table, flow channels opened in the fixed shaft and the negative pressure shaft tube. The negative pressure end of the negative pressure pump is connected to a negative pressure tube, and the other end of the negative pressure tube is connected to the positioning suction cup through the flow channel. A pressure sensor is provided at the connection between the negative pressure pump and the negative pressure tube. A single-chip microcomputer is installed on the feeding rack, and the data terminal of the pressure sensor is connected to the single-chip microcomputer in terms of data.

[0013] The beneficial effect of adopting the above further scheme is that when the negative pressure shaft tube performs negative pressure absorption on the formed hinge accessories, the negative pressure pump works and generates negative pressure in the positioning suction cup until the feedback value of the air pressure sensor reaches the set value. By setting the negative pressure state above the negative pressure shaft tube or the positioning suction cup, the positioning suction cup can then achieve stable absorption of the formed hinge accessories.

[0014] Furthermore, the wire releasing mechanism includes a winding roller rotatably connected to a feed rack, the hinge profile is wound on the winding roller, a first motor and a second motor are respectively installed on the sides of the feed rack, the output shaft end of the first motor is fixedly connected to the winding roller, two conveying rollers are rotatably installed on the feed rack and at positions adjacent to the lower die seat, a feeding gap that cooperates with the hinge profile is fixedly arranged between the two conveying rollers, a linkage gear is installed at the tail end of the two conveying rollers, the two linkage gears are meshed with each other, and the output shaft end of the second motor is fixedly connected to one of the conveying rollers.

[0015] The beneficial effect of adopting the above further scheme is that when the hinge profile is processed, the first motor and the second motor work synchronously at a set interval cycle. During the working cycle of the first motor and the second motor, the hinge profile is released to a specified length and processed between the upper mold and the lower mold base.

[0016] Furthermore, the reciprocating drive module includes a circular shaft rotatably connected to the side of the feed rack, a first belt is transmission-connected between the circular shaft and the roller, a half-tooth gear is installed on the circular shaft, a tooth plate is installed on the side of the two stress frames, the two tooth plates are adapted to the half-tooth gear transmission, the two tooth plates are respectively arranged on both sides of the half-tooth gear, and a group of third elastic limiters are installed between the two stress frames and the feed rack.

[0017] Furthermore, the reciprocating drive module also includes a pulley rotatably connected to the side of the feed rack, a second belt is installed on the pulley for transmission, the two sanding rollers, the pulley and the round shaft are all connected to the second belt for transmission, and a guide roller is rotatably installed on the feed rack, and the guide roller is in contact with the hinge profile.

[0018] The beneficial effect of adopting the above further scheme is that when the hinge profile is released, the round shaft rotates at a set speed. After the round shaft rotates, the two stress frames are reciprocated within the set stroke. When the two stress frames reciprocate, the layout angle and layout shape of the hinge profile are reciprocated, thereby performing multi-directional shaping on the hinge profile to reduce the stress and curvature of the hinge profile when it is released from the roller. By reducing the stress and curvature of the hinge profile, the accurate quantitative release of the hinge profile and the precise positioning processing of the hinge profile between the upper mold and the lower mold base are facilitated. When the hinge profile is released, the sanding rollers rotate at a set speed relative to the hinge profile. After the two sanding rollers rotate, two-way sanding of the inner and outer surfaces of the hinge profile is achieved. Through two-way pre-sanding, the secondary sanding time of the formed hinge fittings in the sanding cylinder is shortened. At the same time, by reciprocally changing the laying angle and laying shape of the hinge profile, the sanding angle or sanding intensity of the sanding rollers on the hinge profile can be reciprocally changed, thereby improving the sanding effect of the hinge profile.

[0019] Further, the biaxial drive module includes a radial drive module installed on the frame. A lifting frame is drivingly installed on the radial drive module. An axial drive module is installed on the lifting frame. The axial drive module is drivingly connected to the moving table.

[0020] The beneficial effects of the present invention are as follows: 1) When the present invention works, through the settings of the wire releasing mechanism, the reciprocating drive module, and the biaxial drive module, the device can automatically complete the punching and forming of the hinge profile, the automatic blanking of the formed hinge fittings, the automatic suction of the blanked hinge fittings, and the multi-directional and all-round sanding and grinding operations of the sucked hinge fittings in an automated production line manner. Subsequently, the automation degree and functionality of the device are effectively improved. Moreover, when the device sands and processes the hinge fittings, multi-directional synchronous rotary vibration sanding can be achieved, effectively improving the sanding efficiency and sanding effect of the device on the hinge fittings.

[0021] 2) In the present invention, when the sanding cylinder is in use, a sufficient amount of polishing sand is stored inside the sanding cylinder, and the polishing sand maintains a set particle fineness. When the formed hinge fittings penetrate to a specified depth inside the sanding cylinder, the motor works and outputs a rotational speed in a set state. After the motor outputs the rotational speed, on the one hand, the formed hinge fittings rotate at a set speed inside the sanding cylinder, and on the other hand, the formed hinge fittings vibrate synchronously in the axial and longitudinal directions during the rotation process. Through the rotation and two-way vibration of the formed hinge fittings inside the sanding cylinder, the angle at which the sand in the sanding cylinder acts on the formed hinge fittings is reciprocally changed, thereby effectively improving the sanding efficiency and sanding effect of the formed hinge fittings after punching. Moreover, through the above sanding structure setting of the formed hinge fittings, the sanding dead angle of the formed hinge fittings can be effectively reduced.

[0022] 3) In the present invention, when the hinge profile is released, the round shaft rotates at a set speed. After the round shaft rotates, the two stress frames reciprocate within a set stroke. After the two stress frames reciprocate, the laying angle and laying shape of the hinge profile are reciprocally changed, so as to perform multi-directional shaping on the hinge profile to reduce the stress and curvature when the hinge profile is released from the winding roller. By reducing the stress and curvature of the hinge profile, it is then convenient for the precise quantitative release of the hinge profile and the precise positioning processing between the upper die and the lower die base. Moreover, when the hinge profile is released, the sanding roller rotates relative to the hinge profile at a set speed. After the two sanding rollers rotate, the two-way sanding of the inner and outer surfaces of the hinge profile is realized. Through two-way pre-sanding, the secondary sanding time of the formed hinge fitting in the sanding cylinder is shortened. At the same time, through the reciprocal change of the laying angle and laying shape of the hinge profile, the sanding angle or sanding intensity of the sanding roller on the hinge profile can be reciprocally changed, thereby improving the sanding effect of the hinge profile.

[0027] When the lower die base 13 and the upper die 16 are fitted together, a forming cavity for forming the hinge profile 9 is formed. After the forming cavity is formed, on the one hand, the profile to be processed is cut on the hinge profile 9, and on the other hand, the stamping forming operation of the cut profile on the hinge profile 9 can be completed; The dual-axis driving module 2 includes a radial transmission module installed on the frame 1, a lifting frame is installed on the radial transmission module, an axial transmission module is installed on the lifting frame, and the axial transmission module is connected to the moving stage 5 in a transmission manner; A bidirectional vibration module is installed on the moving platform 5, and a vertical vibration frame 6 capable of bidirectional synchronous vibration is connected to the bidirectional vibration module. A negative pressure shaft tube 7 is rotatably installed on the vertical vibration frame 6, and a positioning suction cup 8 is connected to the bottom end of the negative pressure shaft tube 7. A negative pressure generating module is arranged inside the negative pressure shaft tube 7; The bidirectional vibration module includes a transverse vibration frame 19, a group of first elastic limiters 20 are installed between the transverse vibration frame 19 and the moving platform 5, a motor 21 is installed on the moving platform 5, a transverse protrusion 22 is fixedly installed on the output shaft end of the motor 21, and a first guide wheel 23 is rotatably installed on the transverse vibration frame 19, and the first guide wheel 23 is in contact with the transverse protrusion 22; A fixed shaft 24 is rotatably mounted on the transverse vibration frame 19, and an elastic tension belt 25 is transmission-connected to the output shaft end of the motor 21, and the fixed shaft 24 is transmission-connected to the elastic tension belt 25; A set of second elastic stoppers 26 is installed between the transverse vibration frame 19 and the vertical vibration frame 6. A straight shaft 27 is rotatably installed on the transverse vibration frame 19, and the straight shaft 27 is driven by the fixed shaft 24. A parachute linkage gear 37 is mounted on both the straight shaft 27 and the fixed shaft 24, and the two parachute linkage gears 37 are meshed with each other; A vertical protrusion 28 is installed on the straight shaft 27, and a second guide wheel 29 is rotatably installed on the vertical vibration frame 6. The second guide wheel 29 is transmission-connected with the vertical protrusion 28, and the negative pressure shaft tube 7 is driven by the fixed shaft 24; A coupling groove with an opening at the bottom is fixedly provided inside the fixed shaft 24, and a sliding section is provided on the negative pressure shaft tube 7. The sliding section is slidably connected with the coupling groove, and the cross sections of the sliding section and the coupling groove are both regular polygons.

[0028] After the cut profile is punched and formed on the hinge profile 9, the formed hinge accessory is kept on the lower die seat 13. Then, the linear transmission module 14 sets the position of the punching table 15 so that the punching table 15 moves out from just above the lower die seat 13. After the punching table 15 moves out from just above the lower die seat 13, under the driving action of the dual-axis driving module 2, the negative pressure shaft tube 7 and the positioning suction cup 8 move to just above the formed hinge accessory. When the dual-axis driving module 2 drives the moving table 5 to move, the motor 21 remains stationary, thereby facilitating the accurate positioning of the negative pressure shaft tube 7 and the positioning suction cup 8 relative to the formed hinge accessory. When the negative pressure shaft tube 7 is accurately positioned relative to the formed hinge part, the bottom surface of the positioning suction cup 8 is closely fitted with the formed hinge part, and negative pressure is generated in the positioning suction cup 8, thereby realizing negative pressure absorption of the formed hinge part on the lower die seat 13. After the formed hinge part is completely absorbed by the negative pressure, the formed hinge part is moved to a specified depth in the sanding cylinder 4 under the driving action of the dual-axis driving module 2; When the sanding cylinder 4 is in use, a sufficient amount of abrasive for polishing is stored inside the sanding cylinder 4, and the abrasive for polishing maintains a set particle fineness. After the formed hinge fitting penetrates into the sanding cylinder 4 to a specified depth, the motor 21 operates and outputs a rotational speed in a set state. After the motor 21 outputs the rotational speed, on the one hand, it causes the formed hinge fitting to rotate in the sanding cylinder 4 at a set speed, and on the other hand, it causes the formed hinge fitting to vibrate synchronously in the axial and longitudinal directions during the rotation process. By the rotation and bi-directional vibration of the formed hinge fitting in the sanding cylinder 4, the angle at which the abrasive in the sanding cylinder 4 acts on the formed hinge fitting is reciprocally changed, thereby effectively improving the sanding efficiency and sanding effect of the formed hinge fitting after punching. Moreover, through the above sanding structure setting of the formed hinge fitting, the sanding dead angle of the formed hinge fitting can be effectively reduced. Both the first elastic limiting member 20 and the second elastic limiting member 26 include a T-shaped limiting rod, and a limiting spring is sleeved on the T-shaped limiting rod; The negative pressure generating module includes a negative pressure pump 30 installed on the moving table 5 and flow channels opened in the fixed shaft 24 and the negative pressure shaft tube 7. The negative pressure end of the negative pressure pump 30 is connected to a negative pressure tube 31, and the other end of the negative pressure tube 31 is connected to the positioning suction cup 8 through the flow channel. An air pressure sensor is provided at the connection between the negative pressure pump 30 and the negative pressure tube 31. A single-chip microcomputer 32 is installed on the feeding frame 3, and the data end of the air pressure sensor is connected to the single-chip microcomputer 32 in terms of data.

[0029] When the negative pressure shaft tube 7 sucks the formed hinge fitting by negative pressure, the negative pressure pump 30 operates and causes negative pressure to be generated in the positioning suction cup 8 until the feedback value of the air pressure sensor reaches the set value. Through the negative pressure state setting above the negative pressure shaft tube 7 or the positioning suction cup 8, the stable suction of the formed hinge fitting by the positioning suction cup 8 is thus realized; A wire releasing mechanism is installed on the feeding frame 3, and a hinge profile 9 is unreeled on the wire releasing mechanism; A reciprocating driving module is provided on the feeding frame 3, and two reciprocatingly movable stress frames 10 are drivingly connected to the reciprocating driving module. A rotatable sanding roller 11 and two symmetrically arranged pinch rollers 12 are rotatably connected between the inner surfaces of each stress frame 10.

[0030] The wire releasing mechanism includes a winding roller 33 rotatably connected to the feeding frame 3, and the hinge profile 9 is wound around the winding roller 33. A first motor 34 and a second motor 35 are respectively installed on the side surface of the feeding frame 3. The output shaft end of the first motor 34 is fixedly connected to the winding roller 33. Two conveying rollers 36 are rotatably installed on the feeding frame 3 at a position adjacent to the lower die base 13. An inlet gap matching the hinge profile 9 is fixedly provided between the two conveying rollers 36. A linkage gear 37 is installed at the tail end of each of the two conveying rollers 36, and the two linkage gears 37 mesh with each other. The output shaft end of the second motor 35 is fixedly connected to one of the conveying rollers 36.

[0031] When the hinge profile 9 is processed, the first motor 34 and the second motor 35 work synchronously at a set interval period. During the working cycles of the first motor 34 and the second motor 35, the hinge profile 9 is released by a specified length and processed between the upper die 16 and the lower die base 13.

[0032] The reciprocating drive module includes a circular shaft 38 rotatably connected to the side of the feeding frame 3. There is a first belt in transmission connection between the circular shaft 38 and the winding roller 33. A semi-toothed gear 39 is installed on the circular shaft 38. Tooth plates 40 are installed on the sides of the two stress frames 10. Both tooth plates 40 are in transmission fit with the semi-toothed gear 39.

A set of third elastic limit members 41 are installed between the two stress frames 10 and the feeding frame 3. The reciprocating drive module further includes a pulley 42 rotatably connected to the side of the feeding frame 3. A second belt is installed in transmission on the pulley 42. The two sanding rollers 11, the pulley 42 and the circular shaft 38 are all in transmission connection with the second belt. A guide roller 43 is rotatably installed on the feeding frame 3, and the guide roller 43 is in contact with the hinge profile 9.

[0033] When the hinge profile 9 is released, the circular shaft 38 rotates at a set speed. After the circular shaft 38 rotates, the two stress frames 10 reciprocate within a set stroke. When the two stress frames 10 reciprocate, the layout angle and layout shape of the hinge profile 9 are reciprocally changed, so as to perform multi-directional shaping on the hinge profile 9 to reduce the stress and curvature of the hinge profile 9 when it is released from the winding roller 33. By reducing the stress and curvature of the hinge profile 9, it is then convenient for the precise quantitative release of the hinge profile 9 and the precise positioning processing of the hinge profile 9 between the upper die 16 and the lower die base 13. And when the hinge profile 9 is released, the sanding rollers 11 rotate relative to the hinge profile 9 at a set speed. After the two sanding rollers 11 rotate, the two-way sanding of the inner and outer surfaces of the hinge profile 9 is realized. Through two-way pre-sanding, the secondary sanding time of the formed hinge fitting in the sanding cylinder 4 is shortened. At the same time, through the reciprocal change of the layout angle and layout shape of the hinge profile 9, the sanding angle or sanding intensity of the sanding rollers 11 on the hinge profile 9 can be reciprocally changed, so as to improve the sanding effect of the hinge profile 9.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
