DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 9 , the present invention provides a technical solution:

[0032] A gantry robot welding station includes a head and tail frame positioner 100, a welding tool 200 installed on the head and tail frame positioner 100, a movable ground rail 300 set aside, and a welding robot 400 moving on the movable ground rail 300, wherein the welding robot 400 is connected to the welding system.

[0033] The welding tool 200 includes a tool frame 201, which is rectangular in shape as a whole. Several moving components 202 are slidably connected to the tool frame 201. Channel steel positioning components 203 for fixing channel steels and lifting components 204 for supporting channel steels are distributed on the top of the moving components 202. An end face limiting component 205 is vertically fixed to the top of one side of the tool frame 201. Head and tail frame turntables 207 connected to the head and tail frame positioner 100 are vertically fixed at both ends of the tool frame 201. A wire trough component 206 for collecting lines is provided on one side of the tool frame 201.

[0034] Specifically, if Figure 1-Figure 5 As shown, the moving component 202 includes an I-shaped frame 202a slidably connected to the tooling frame 201, the I-shaped frame 202a is mounted on the tooling frame 201, and both sides of the bottom end of the I-shaped frame 202a are fixed with slide rails 202b along the length direction of the tooling frame 201, and both sides of the bottom end of the tooling frame 201 are fixed with slide rails 202c adapted to the slide rails 202b.

[0035] A rack 202f is fixed to one side of the tooling frame 201, and a driving member 202d is installed at the bottom of the tooling frame 201. The driving member 202d is a servo motor, and a gear 202e meshing with the rack 202f is fixed to the output end of the driving member 202d.

[0036] Start the driving component 202d. The driving component 202d is a combination of the driving motor and the gearbox. The output shaft of the driving motor is transmitted to the gearbox, and the output end of the gearbox is transmitted to the gear 202e. The driving component 202d fixed on the I-frame 202a drives the gear 202e to engage and rotate on the rack 202f, thereby driving the I-frame 202a to move linearly on the tooling frame 201. During the movement, the slide rail 202b is slidably connected with the slideway 202c, so that the I-frame 202a moves stably on the tooling frame 201, thereby adjusting the specified position of the moving components 202 in different positions, thereby adapting to different gantry welding requirements.

[0037] Specifically, if Figure 1 、 Figure 6 As shown, the channel steel positioning assembly 203 includes a mounting base plate 203a fixed to one side of the top end of the I-frame 202a by bolts, and a screw rod structure 203c is provided on the mounting base plate 203a along its length direction.

[0038] The screw structure 203c is symmetrically connected to a sliding plate 203b, a clamping plate 203d with a clamping slot is vertically fixed to one side of the top of the sliding plate 203b, and a baffle 203f is vertically fixed to the other side of the top of the sliding plate 203b. A pushing block 203g is vertically movably connected to the baffle 203f for pushing the channel steel into contact with the baffle 203f. A third cylinder 203h is fixed to the other side of the baffle 203f. The output end of the third cylinder 203h passes through the baffle 203f and is fixed to the pushing block 203g. The clamping plate 203d has a built-in buckle 203e that can clamp the bottom edge of the channel steel downwards.

[0039] Place the two channel steels between the baffle 203f and the clamping plate 203d accordingly. The bottom of the channel steel is supported by the clip 203e, and the third cylinder 203h drives the pushing block 203g to push the channel steel to move in the direction of the clamping plate 203d, and then the pushing block 203g cooperates with the clamping plate 203d to clamp the channel steel between the two. The screw structure 203c includes a motor fixed to the I-frame 203a, and a bidirectional threaded rod is fixed to the output end of the motor. The bidirectional threaded rod is actually a kind of ball screw. The focus of the bidirectional threaded rod is centered on the midpoint between the two sliding plates. The threads on both sides are in opposite directions. The threaded rod passes through and is threadedly connected to the two sliding plates. Then, the motor of the screw structure 203c drives the bidirectional threaded rod to rotate. Under the action of the threaded connection between the sliding plate 203b and the bidirectional threaded rod, by controlling the forward and reverse rotation of the motor, the distance between the two sliding plates 203b is adjusted under the action of the threaded connection between the two sliding plates 203b and the bidirectional threaded rod, thereby adjusting the distance between the channel steel clamped and fixed between the baffle 203f and the clamping plate 203d.

[0040] Specifically, if Figure 1-Figure 5As shown, the lifting assembly 204 includes a support column 204a vertically connected to the other side of the top of the I-frame 202a. There are four support columns 204a on each I-frame 202a, two of which are used in a group and are symmetrically distributed on both sides of the top of the I-frame 202a. The tops of a group of support columns 204a are commonly connected to a support plate 204b.

[0041] The support columns 204a of different groups are vertically fixed with connecting blocks 204c, and the connecting blocks 204c are vertically slidably connected with guide rods 204d. The guide rods 204d are connected with mounting plates 204e. The middle of the other side of the top of the I-shaped frame 202a is vertically fixed with a first cylinder 204f that lifts up the mounting plate 204e.

[0042] The channel steel is placed on the support plate 204b. When the width between the channel steels cannot be placed on the support plate 204b, the first cylinder 204f drives the mounting plate 204e to move upwards, thereby making up the width required for installation.

[0043] And when the support plate 204b is not high enough, the first cylinder 204f can be used to drive the mounting plate 204e to move upward to lift the channel steel, thereby increasing practicality.

[0044] Specifically, if Figure 1 、 Figure 7-Figure 9 As shown, the end face limiting assembly 205 includes a fixing seat 205a fixed vertically on the top of one side of the tooling frame 201, and the fixing seat 205a is slidably connected to the end facing the tooling frame 201 with a connecting plate 205b, and a pressing plate 205c is vertically fixed in the middle of the connecting plate 205b.

[0045] A second cylinder 205d is provided in the middle of the fixed seat 205a for driving the connecting plate 205b to slide linearly. A limiting plate 205e is vertically fixed to one end of the fixed seat 205a facing the clamping plate 205c. Adjusting parts 205f are connected between the limiting plate 205e and the four corners of the fixed seat 205a. Limiting slides 205g that are slidably connected to the fixed seat 205a are vertically fixed at both ends of the connecting plate 205b.

[0046] During operation, the limit plate 205e and the clamping plate 205c are in a separated state, and the channel steel is located between the two. Then, by controlling the second cylinder 205d to retract, the connecting plate 205b connected to the output end of the second cylinder 205d is driven. Since the clamping plate 205c is fixed to the connecting plate 205b, the clamping plate 205c is driven to move, and then cooperate with the limit plate 205e to achieve clamping and fixing of the channel steel. In order to further ensure the linear movement of the clamping plate 205c, it is achieved under the sliding connection between the limit slide 205g and the fixed seat 205a. At the same time, since the limit plate 205e is fixed to 205a by an adjusting member 205f, the adjusting member 205f is a bolt. Therefore, when needed in the future, the position of the limit plate 205e on the fixed seat 205a can be adjusted by screwing the adjusting member 205f by a tool according to the size of the channel steel to meet production needs.

[0047] Working principle:

[0048] Start the driving member 202d. The driving member 202d is a driving motor that cooperates with the gearbox. The output shaft of the driving motor is driven by the gearbox, and the output end of the gearbox is driven by the gear 202e. The driving member 202d fixed on the I-shaped frame 202a drives the gear 202e to mesh and rotate on the rack 202f, thereby driving the I-shaped frame 202a to move linearly on the fixture frame 201. During the movement, the slide rail 202b is slidably connected with the slideway 202c, so that the I-shaped frame 202a can move stably on the fixture frame 201, thereby adjusting the designated position of the moving assembly 202 at different positions to meet different gantry welding requirements.

[0049] Place the two channel steels between the baffle 203f and the clamping plate 203d accordingly. The bottom of the channel steel is supported by the clip 203e, and the third cylinder 203h drives the pushing block 203g to push the channel steel to move in the direction of the clamping plate 203d, and then the pushing block 203g cooperates with the clamping plate 203d to clamp the channel steel between the two. The screw structure 203c includes a motor fixed to the I-frame 203a, and a bidirectional threaded rod is fixed to the output end of the motor. The bidirectional threaded rod is actually a kind of ball screw. The focus of the bidirectional threaded rod is centered on the midpoint between the two sliding plates. The threads on both sides are in opposite directions. The threaded rod passes through and is threadedly connected to the two sliding plates. Then, the motor of the screw structure 203c drives the bidirectional threaded rod to rotate. Under the action of the threaded connection between the sliding plate 203b and the bidirectional threaded rod, the distance between the two sliding plates 203b is adjusted under the action of the threaded connection between the two sliding plates 203b and the bidirectional threaded rod by controlling the forward and reverse rotation of the motor. The distance between the two sliding plates 203b is adjusted, thereby adjusting the distance between the channel steel between the baffle 203f and the clamping plate 203d by clamping the top of the two sliding plates 203b;

[0050] The channel steel is placed on the support plate 204b. When the width between the channel steels cannot be placed on the support plate 204b, the first cylinder 204f drives the mounting plate 204e to move upwards, thereby making up the width required for installation.

[0051] When the support plate 204b is not high enough, the first cylinder 204f can be used to drive the mounting plate 204e to move upward to lift the channel steel, thereby increasing practicality.

[0052] During operation, the limit plate 205e and the clamping plate 205c are in a separated state, and the channel steel is located between the two. Then, by controlling the second cylinder 205d to retract, the connecting plate 205b connected to the output end of the second cylinder 205d is driven. Since the clamping plate 205c is fixed to the connecting plate 205b, the clamping plate 205c is driven to move, and then cooperate with the limit plate 205e to achieve clamping and fixing of the channel steel. In order to further ensure the linear movement of the clamping plate 205c, it is achieved under the sliding connection between the limit slide 205g and the fixed seat 205a. At the same time, since the limit plate 205e is fixed to 205a by an adjusting member 205f, the adjusting member 205f is a bolt. Therefore, when needed in the future, the position of the limit plate 205e on the fixed seat 205a can be adjusted by screwing the adjusting member 205f by a tool according to the size of the channel steel to meet production needs.
