Description

Technical Field

[0001] The present invention relates to the technical field of welding fixtures, and particularly to a fixture tooling for the welding process of a bumper beam. <了 Background Art

[0002] A bumper beam is usually made of high-strength steel, with a complex shape and extremely high requirements for welding accuracy and quality. Therefore, when welding a bumper beam, a dedicated fixture tooling for welding is required to handle the above situation.

[0003] The clamping components and their attached structures on the existing fixture tooling cannot be separated from the combined body of the bumper beam and the energy absorber at a large angle or by a large margin after spot welding the bumper beam and the energy absorber, resulting in them blocking or surrounding the combined body, interfering with the welding of the welds between the combined bodies, and affecting the normal welding and welding efficiency of the bumper beam and the energy absorber. In addition, although some clamping components and their attached structures are set to be able to withdraw at a large angle or by a large margin as described above, the withdrawal operations of such multiple clamping components and their attached structures need to be performed step by step in sequence, and the operation is rather troublesome and inconvenient. Summary of the Invention

[0004] In view of this, the present invention provides a fixture tooling for the welding process of a bumper beam to solve the problem that the withdrawal operations of multiple clamping components and their attached structures need to be performed step by step in sequence, and the operation is rather troublesome and inconvenient.

[0005] The technical solution proposed by the present invention is: a fixture tooling for the welding process of a bumper beam, which is used to clamp and fix a bumper beam and an energy absorber together for welding the two. Specifically, it includes a vertical support. There are two symmetrically arranged vertical supports, and each vertical support is composed of a bottom plate and two vertical support rods symmetrically welded to the top of the bottom plate. A swing plate is rotatably installed at the top of the vertical support rod. A longitudinal clamping plate pushed by a spring is slidably arranged at the front end part of the swing plate, and an L-shaped force transmission rod is welded to the rear end part of the swing plate. A square sliding sleeve pushed by a spring for positioning is slidably installed at the top part of the vertical support rod. A connecting rod is rotatably connected between the square sliding sleeve and the L-shaped force transmission rod. A vertical support force transmission plate is welded to the bottom of the square sliding sleeve, and a square sliding sleeve slidably engaged with the vertical support rod is also welded to the bottom side part of the vertical support force transmission plate. A horizontal stepping shaft is welded between the bottoms of the two vertical support force transmission plates on the same side of the two vertical supports. A longitudinal connecting plate is welded between the two square sliding sleeves on the upper side of the vertical supports.

[0006] Further, a U-shaped card slot is formed around between the top parts of the two vertical support rods on the vertical support and the upper longitudinal reinforcing plate. The two ends of the bumper beam are respectively clamped in the two U-shaped card slots of the two vertical supports. The energy absorption box is placed between two longitudinal clamping plates on the vertical bracket, and is clamped and fixed in a state of being connected to the anti-collision beam and waiting to be welded by the two longitudinal clamping plates.

[0007] Furthermore, a hexagonal sliding shaft is welded to the back of the middle section of the longitudinal splint, and the hexagonal sliding shaft is slidably fitted with the top part of the vertical bracket. The spring compression sleeve that pushes the longitudinal splint is mounted on the part of the hexagonal sliding shaft located between the longitudinal splint and the vertical bracket.

[0008] Furthermore, an L-shaped mounting plate is welded to the top portion of the vertical support rod, and the tail end of the swing plate is rotatably connected to the top end of the L-shaped mounting plate; Two longitudinal reinforcing plates are welded at upper and lower intervals between the two vertical support rods on the vertical bracket, and a vertical positioning shaft is welded between the two longitudinal reinforcing plates. The longitudinal connecting plate is slidably matched with the vertical positioning shaft, and the spring for pushing and positioning the square sliding sleeve is installed on the vertical positioning shaft and compressed between the longitudinal connecting plate and the lower longitudinal reinforcing plate.

[0009] Furthermore, a U-shaped mounting frame is welded to the inner side of the bottom end portion of the two vertical support rods on the vertical bracket, and an I-shaped mounting frame is welded between the two U-shaped mounting frames; A transverse drive shaft is slidably installed on the two I-shaped mounting frames of the two vertical brackets, and two kick plates are symmetrically welded at both ends of the transverse drive shaft.

[0010] Furthermore, an insertion shaft which is positioned by spring pushing is slidably passed through the U-shaped mounting frame and the vertical support rod, and a pull rod is rotatably connected between the tail end of the insertion shaft and the horizontal driving shaft.

[0011] Furthermore, the vertical support force transmission plate is slidably fitted with the outer side of the vertical support rod, the bottom end portion of the vertical support force transmission plate is an L-shaped bending structure, and a positioning hole is opened through the vertical support force transmission plate near the L-shaped bending portion.

[0012] Furthermore, when the vertical support force transmission plate slides downward, its L-shaped bent portion comes into contact with the head end of the insertion shaft, and when the L-shaped bent portion passes through the insertion shaft, the head end of the insertion shaft is plugged into and fitted with the positioning hole.

[0013] The fixture for welding the anti-collision beam provided by the present invention has the following beneficial effects: 1. The two longitudinal splints and the two swing plates serve as components and auxiliary clamping mechanisms for clamping and positioning the energy absorption box. The overall installation adopts a swinging installation configuration. After completing the spot welding connection between the energy absorption box and the anti-collision beam, they can swing downward and away from the energy absorption box at a large angle, and largely separate from the energy absorption box, leaving a large amount of space on both sides of the energy absorption box for welding the welds between the energy absorption box and the anti-collision beam. This can prevent the two longitudinal splints and the two swing plates from being able to largely separate from the energy absorption box when the energy absorption box is loosened under the above circumstances, and they are still intercepted in the space on both sides of the anti-collision beam at a close distance, causing obstruction and interference in the welding of the above welds, which helps to ensure the normal welding and welding efficiency of the energy absorption box and the anti-collision beam.

[0014] 2. Through the power transmission of the four vertical support force transmission plates, the foot can drive any one of the two horizontal pedal shafts to drive the four square sliding sleeves on the two vertical brackets to move down synchronously. In this way, through the power transmission of the two vertical support force transmission plates and the synchronous transmission of the two longitudinal connecting plates, only the simple operation of stepping down the horizontal pedal shaft with the foot can drive the four square sliding sleeves to move down synchronously, control the four longitudinal splints and the four swing plates on the two vertical brackets to swing away from the energy absorption box, and complete the loosening of the two energy absorption boxes and the large-scale evacuation and disengagement of the four longitudinal splints and the four swing plates from the energy absorption box at one time. This can save the tedious steps of swinging the four swing plates step by step to perform the above operations, and the operation is convenient and efficient.

[0015] 3. Four pull rods, four plug shafts and a transverse drive shaft are connected together to form four sets of crank slider mechanisms. Through the four sets of crank slider mechanisms, the sliding transverse drive shaft can drive the four plug shafts to slide inward synchronously and be pulled out of the four positioning holes, thereby loosening the four square sleeves at one time. This saves the trouble of sliding the four plug shafts step by step to unlock and loosen the four square sleeves, and helps to simplify the operation and use steps of the fixture tooling.

[0029] The following is a detailed description of the specific details, implementation steps, functions and interrelationships of the above features, as well as their roles in implementing the present invention: During the welding process, after the energy absorbing box 5 and the anti-collision beam 4 are connected by spot welding, the two longitudinal clamping plates 105 and the two swing plates 104 need to be swung away from the energy absorbing box 5 to loosen the energy absorbing box 5.

[0030] The two longitudinal clamps 105 and the two swing plates 104 serve as components and auxiliary clamping mechanisms for clamping and positioning the energy absorption box 5, and the overall installation adopts a swinging installation configuration. After completing the spot welding connection between the energy absorption box 5 and the anti-collision beam 4, they can swing downward and away from the energy absorption box 5 at a large angle, and withdraw and disengage from the energy absorption box 5 to a large extent, leaving a large range of space on both sides of the energy absorption box 5 for welding the welds between the energy absorption box 5 and the anti-collision beam 4. This can avoid the two longitudinal clamps 105 and the two swing plates 104 from being able to withdraw and separate from the energy absorption box 5 to a large extent when the energy absorption box 5 is loosened under the above circumstances, and still being intercepted in the space on both sides of the anti-collision beam 4 at a close distance, causing obstruction and interference in the welding of the above welds, which helps to ensure the normal welding and welding efficiency of the energy absorption box 5 and the anti-collision beam 4.

[0031] The two longitudinal splints 105, the two swing plates 104, the two L-shaped force transmission rods 1041 and the two square sleeves 107 are connected together to form two sets of crank slider mechanisms. Through the two sets of crank slider mechanisms and the synchronous transmission of the longitudinal connecting plate 1072, sliding any square sleeve 107 up and down can drive the two square sleeves 107 to slide synchronously, drive the two longitudinal splints 105 and the two swing plates 104 to swing towards each other, and implement tension and loosening of the energy absorption box 5; the top thrust of the spring on the vertical positioning shaft 106 can push the longitudinal connecting plate 1072 and the two square sleeves 107 to maintain them in the upper sliding high position, and make the two swing plates 104 is positioned in an upward swing upright support state, thereby keeping the two longitudinal splints 105 in a state of pressing contact with both sides of the energy absorbing box 5, and clamping and positioning the energy absorbing box 5; when the two swing plates 104 swing upward and close to the energy absorbing box 5 and are placed in an upright state, the springs on the two hexagonal sliding shafts 1051 transmit the pressing force to the two longitudinal splints 105 through the two places, so that the two longitudinal splints 105 press on both sides of the energy absorbing box 5 to clamp the energy absorbing box 5, and when the two longitudinal splints 105 are pressed and clamped with the energy absorbing box 5, they compress the springs on the two hexagonal sliding shafts 1051 under the reverse push of the energy absorbing box 5 to slide away from the energy absorbing box 5.

[0032] By the power transmission of the four vertical support force transmission plates 108, the foot drives any one of the two horizontal treading shafts 109, which can drive the four square sliding sleeves 107 on the two vertical brackets 1 to move downward synchronously. In this way, through the power transmission of the two vertical support force transmission plates 108 and the synchronous transmission of the two longitudinal connecting plates 1072, it is only necessary to step on the horizontal treading shaft 109 to drive the four square sliding sleeves 107 to move downward synchronously, and control the four longitudinal splints 105 and the four swing plates 104 on the two vertical brackets 1 to swing away from the energy absorption box 5, so as to complete the loosening of the two energy absorption boxes 5 and the large-scale evacuation and disengagement operations of the four longitudinal splints 105 and the four swing plates 104 from the energy absorption box 5 at one time. This can save the tedious steps of swinging the four swing plates 104 step by step to perform the above operations, and the operation is convenient and efficient. In the above process, when the four square sliding sleeves 107 slide down, the two vertical connecting plates 1072 therebetween compress the springs on the two vertical positioning shafts 106 respectively. When the four vertical support force transmission plates 108 follow the horizontal pedal shaft 109 and are driven to slide down by the foot, the L-shaped bent parts on the bottom side correspond to the head ends of the four plug shafts 3. When the four L-shaped bent parts are in contact with the head ends of the four plug shafts 3, through their bending guiding effect, they can push the head ends of the four plug shafts 3 to slide inward and hide in the four vertical support force transmission plates 108, leaving a position for the vertical support force transmission plates 108 to continue to slide down along the four vertical support rods 102, and the four plug When the shaft 3 is driven to slide inward, the spring on it is compressed. Thereafter, as the four vertical support force transmission plates 108 continue to slide down, when its L-shaped bent portion passes through the four plug-in shafts 3, the four plug-in shafts 3 can be aligned with the four positioning holes 1081 and automatically plugged into and matched with the four positioning holes 1081 under the reverse push of the springs thereon. When the four plug-in shafts 3 are plugged into and matched with the four positioning holes 1081, the two vertical support force transmission plates 108 and the four square sliding sleeves 107 can be plugged and positioned in a low sliding position, and the two longitudinal splints 105 and the two swing plates 104 can be kept in a state of loosening the energy absorption box 5 by swinging down and in a state of being largely evacuated and separated from the energy absorption box 5.

[0033] When one welding operation is completed, the welded energy absorption box 5 and anti-collision beam 4 combination is removed, and when the new energy absorption box 5 and anti-collision beam 4 to be welded are replaced, the four plug shafts 3 are slid inward synchronously, and the four plug shafts 3 are controlled to be pulled out from the four positioning holes 1081, and the four square sliding sleeves 107 are loosened. When the four square sliding sleeves 107 are loosened, the springs on the two vertical positioning shafts 106 can automatically push the two longitudinal connecting plates 1072 and the four square sliding sleeves 107 to slide up and reset, drive the four longitudinal clamps 105 and the four swing plates 104 to swing upward and reset, control the four swing plates 104 to press and clamp the two newly replaced energy absorption boxes 5, and perform the second welding.

[0034] The four pull rods 301, the four plug shafts 3 and the transverse drive shaft 2 are connected together to form four sets of crank slider mechanisms. Through the four sets of crank slider mechanisms, the sliding transverse drive shaft 2 can drive the four plug shafts 3 to slide inward synchronously and be pulled out of the four positioning holes 1081, thereby loosening the four square sleeves 107 at one time. This saves the trouble of sliding the four plug shafts 3 step by step to unlock and loosen the four square sleeves 107, and helps to simplify the operation and use steps of the fixture tooling.

[0035] The transverse drive shaft 2 is driven by footsteps, and the transverse drive shaft 2 can be driven by kicking through any kick plate 201 .
