[0001] The invention relates to the technical field of welding equipment, in particular to a positioning welding device for processing a hand rod of a container door lock. Background Art

[0002] The container door lock handle is a component used to operate the container door lock. It is usually installed on one side of the container door. It is generally composed of a steel pipe, a handle, a retaining ring, and a lock head. The handle is usually located in the middle of the handle to facilitate the operator to hold and apply force. The retaining ring is used to limit the rotation range of the handle to ensure that it is operated at the correct angle. The lock head is installed at both ends of the handle and cooperates with the lock seat on the container door frame to achieve the locking and unlocking of the container door. In general, the processing technology of the container door lock handle mainly includes raw material preparation, forging, machining, surface treatment and other steps. Among them, the handle is provided with a curved section for the convenience of workers. In order to increase the pressure-bearing range of the curved section, a reinforcing plate is usually welded on the curved section for reinforcement;

[0003] When welding the reinforcing plate of the hand lever, when the fixing position of the hand lever is offset and tilted, when the worker fixes the reinforcing plate and makes the reinforcing plate fit the hand lever, the fitting position is wrong, which affects the normal use of the hand lever. Summary of the invention

[0007] A displacement mechanism, wherein the displacement mechanism is installed inside the frame, and a connecting plate is installed on the top of the displacement mechanism;

[0008] A pressing mechanism, the pressing mechanism is installed at the center of the top of the connecting plate;

[0009] A welding gun mechanism, the top of which is fixedly connected to the output end of the first cylinder;

[0010] The top of the locking cam is provided with a locking cam which is secured to the locking cam by a locking cam which is secured on the locking cam side.

This causes fluctuations in the welding position and the welding distance of the welding gun, resulting in cold welding when the welding distance is far, affecting the welding effect. The outer side of the side sliding column contacts the inner wall of the frame. The top of the slide plate is fixedly installed with a fourth cylinder, which is symmetrically installed along the center position of the axis of the slide plate, and the output end of the fourth cylinder is fixedly installed with a clamping plate, the bottom of the opposite surface of the clamping plate is fixedly connected to the two ends of the connecting plate, and the top of the slide plate is fixedly installed with a slide rail, which is symmetrically installed along the center position of the axis of the slide plate.

[0012] Preferably, the pressing mechanism includes a fixing frame, the bottom of the fixing frame is fixedly connected to the center position of the top of the connecting plate, and a top plate is slidably installed on the inner wall of the fixing frame, and elastic pads are fixedly installed on both sides of the bottom of the top plate, and a fifth cylinder is fixedly installed at the center position of the top of the fixing frame, the output end of the fifth cylinder passes through the fixing frame and extends into the interior thereof, and a fixing plate is fixedly installed on the output end of the fifth cylinder, and side clamps are symmetrically installed on both sides of the bottom of the fixing plate, and the inclined surfaces of the opposite surfaces of the side clamps are utilized to fix the reinforcing plate through the contact between the two sides of the top of the reinforcing plate and the inclined surfaces of the side clamps, while ensuring the fixing effect, the position of the reinforcing plate is adjusted under the contact pressure so that the reinforcing plate is in the center position of the bending part of the hand rod, so as to avoid the position deviation of the reinforcing plate, which leads to the wrong welding position, and the side clamps The relative surface of the side is an inclined surface inclined from top to bottom toward the outside, and a through groove is provided on the outside of the side clamping block, and a pressing plate is slidably installed at the through groove of the side clamping block, the pressing plate is located between the side clamping blocks, and an arc groove is provided at the center position of the bottom of the pressing plate, and an elastic ring is fixedly installed between the pressing plate and the fixed plate, and the pressing plate cooperates with the elastic ring. In the process of fixing the reinforcing plate, the pressing plate first contacts with the top of the reinforcing plate, and at the same time, in the process of continuing to move downward, the contact pressure compresses the elastic ring to deform it, so that the pressing plate slides upward in the through groove of the side clamping block, and the elastic force is generated by the elastic annular deformation. While pre-fixing the reinforcing plate, a fitting pressure is provided for the contact position between the reinforcing plate and the hand rod to ensure the fitting pressure and avoid gaps at the contact position, which leads to false welding after welding.

[0014] The present invention provides a positioning welding device for processing a container door lock handle. It has the following beneficial effects:

[0015] 1. The positioning welding device for processing the handle of the container door lock cooperates with the pressing block and the positioning block, and uses the inclined surface of the bottom of the pressing block to contact the two ends of the top of the handle. At the same time, with the characteristic that the width of the positioning groove gradually decreases from top to bottom, in the process of fixing the hand lever, the top of the hand lever is made vertically upward, and the center position of the axis of the hand lever corresponds to the center position of the positioning block, so as to avoid the center position of the hand lever being offset from the fixing center when the hand lever is fixed, resulting in the position misalignment of the reinforcing plate and the hand lever, which affects the locking of the container door when the hand lever is in use, and causes the hand lever to be unable to be used normally.

[0016] 2. The positioning welding device for the container door lock handle processing, through the contact between the side sliding column and the frame, cooperates with the slide rail to guide the displacement of the card plate, while reducing the resistance during the movement process, guiding the movement direction to avoid the deviation of the movement direction, resulting in fluctuations in the welding position and the welding distance of the welding gun, resulting in cold welding when the welding distance is far, affecting the welding effect.

[0017] 3. The positioning welding device for processing the handle of the container door lock uses the inclined surfaces of the opposite surfaces of the side clamping blocks. In the process of fixing the reinforcing plate, the top sides of the reinforcing plate are in contact with the inclined surfaces of the side clamping blocks. While ensuring the fixing effect, the position of the reinforcing plate is adjusted under the contact pressure so that the reinforcing plate is at the center of the bend of the hand rod, avoiding the position deviation of the reinforcing plate and causing the welding position error.

[0018] Fourth, the positioning welding device for processing the handle bar of the container door lock first contacts the top of the reinforcing plate through the pressing plate. At the same time, in the process of continuing to move downward, the contact pressure compresses the elastic ring to deform it, so that the pressing plate slides upward in the through groove of the side clamp block, and the elastic ring is deformed to generate elastic force. While pre-fixing the reinforcing plate, it provides fitting pressure for the contact position between the reinforcing plate and the hand bar to ensure the fitting pressure and avoid gaps at the contact position, which leads to cold welding after welding.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe 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.

[0030] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0031] A positioning welding device for processing a container door lock handle, comprising:

[0032] A frame 1, a first cylinder 3 is fixedly mounted on the top of the frame 1, and an output end of the first cylinder 3 penetrates the frame 1 and extends into the interior thereof;

[0033] A displacement mechanism 2, which is installed inside the frame 1, and a connecting plate 7 is installed on the top of the displacement mechanism 2;

[0035] A welding gun mechanism 4, the top of which is fixedly connected to the output end of the first cylinder 3;

[0036] Positioning blocks 6 are fixedly installed on both sides of the top of the connecting plate 7. A positioning groove is opened on the top of the positioning block 6, and the width of the positioning groove gradually decreases from top to bottom. The worker puts the hand rod into the equipment so that the two ends of the hand rod are placed in the positioning grooves of the positioning block 6, and then starts the second cylinder 8 to drive the pressing block 9 to press down, and cooperate with the pressing mechanism 5 to move the pressing block 9 downward to contact the two ends of the hand rod. The second cylinder 8 is fixedly installed on the top of the positioning block 6, and the output end of the second cylinder 8 passes through the positioning block 6 and extends into it, and The output end of the second cylinder 8 is fixedly installed with a pressure block 9. The inclined surface at the bottom of the pressure block 9 cooperates with the positioning groove of the positioning block 6. Through the characteristic that the width of the positioning groove gradually decreases from top to bottom, when the hand lever gradually increases the contact pressure with the positioning block 6, the position of the hand lever is adjusted through the adaptation of the pressure block 9 and the positioning groove, so that the top of the hand lever is vertically upward and the hand lever is at the center position of the positioning block 6. The bottom of the pressure block 9 is a raised inclined surface at the center position, and a slider 10 is fixedly installed at the center position of the bottom of the connecting plate 7.

[0037] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the displacement mechanism 2 includes a slide plate 21 and a third cylinder 22. The slide plate 21 is installed inside the frame 1, and bottom blocks 23 are fixedly installed on both sides of the bottom of the slide plate 21. The third cylinder 22 is fixedly installed inside the frame 1, and the output end of the third cylinder 22 is fixedly connected to the outer side of the bottom block 23. The third cylinder 22 cooperates with the fourth cylinder 25, and the third cylinder 22 drives the slide plate 21 to move longitudinally. The fourth cylinder 25 drives the connecting plate 7 through the clamping plate 26, so that the connecting plate 7 slides and fits with the slide groove of the slide plate 21 through the slider 10, so that the connecting plate 7 moves laterally, and the hand rod and the reinforcing plate move laterally and longitudinally synchronously, and cooperate with the welding gun mechanism 4 for welding processing. A slide groove is opened at the center position of the top of the slide plate 21, and the slide groove of the slide plate 21 slides and fits with the outer side of the slider 10. Side sliding columns 24 are rotatably installed on both sides of the slide plate 21, and the outer side of the side sliding column 24 contacts the inner wall of the frame 1.

[0038] A fourth cylinder 25 is fixedly installed on the top of the slide plate 21, and the fourth cylinder 25 is symmetrically installed along the center position of the axis of the slide plate 21, and a clamping plate 26 is fixedly installed on the output end of the fourth cylinder 25, and the bottom of the opposite surface of the clamping plate 26 is fixedly connected to the two ends of the connecting plate 7. During the longitudinal movement of the slide plate 21, the side sliding column 24 is in contact with the frame 1, and the friction resistance is reduced by rotating during movement. At the same time, the sliding adaptation of the clamping plate 26 slot and the slide rail 27 is utilized to cooperate with the sliding adaptation of the slider 10 and the slide plate 21 to ensure the accuracy during movement. A slide rail 27 is fixedly installed on the top of the slide plate 21, and the slide rail 27 is symmetrically installed along the center position of the axis of the slide plate 21. Slots are provided on both sides of the bottom of the clamping plate 26, and the slots of the clamping plate 26 are slidably adapted to the top of the slide rail 27.

[0039] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the pressing mechanism 5 includes a fixed frame 51, the bottom of the fixed frame 51 is fixedly connected to the center position of the top of the connecting plate 7, and a top plate 52 is slidably installed on the inner wall of the fixed frame 51, and elastic pads 53 are fixedly installed on both sides of the bottom of the top plate 52. A fifth cylinder 55 is fixedly installed at the center position of the top of the fixed frame 51, and the output end of the fifth cylinder 55 passes through the fixed frame 51 and extends to the inside thereof. When fixing the hand rod, the hand rod is placed on the top of the top plate 52, and the hand rod is supported by the top plate 52 under the support of the elastic pad 53. When fixing the hand rod, the elastic deformation of the elastic pad 53 is used to provide a buffer space for the hand rod to move downward, so as to assist in the positioning of the fixed hand rod. After the hand rod is fixed, the worker puts the reinforcing plate into the welding position at the bend of the hand rod, and then drives the fixed plate 54 to move downward through the fifth cylinder 55, so that the fixed plate 54 synchronously drives the side clamping block 56 to move downward, and the output end of the fifth cylinder 55 is fixedly installed with the fixed plate 54, and the side clamping blocks 56 are symmetrically installed on both sides of the bottom of the fixed plate 54. The opposite surface of the side clamp block 56 is an inclined surface inclined outward from top to bottom, and a through groove is opened on the outside of the side clamp block 56, and a press plate 57 is slidably installed at the through groove of the side clamp block 56. The press plate 57 is located between the side clamp blocks 56. During the downward movement, the side clamp blocks 56 cooperate to make the reinforcing plate between the side clamp blocks 56, and during the downward movement, the press plate 57 first contacts the top of the reinforcing plate, and contacts the top of the reinforcing plate through the card groove at the top of the reinforcing plate to perform pre-fixation. Then, the fixed plate 54 continues to move downward, and in the process of moving downward, the contact pressure compresses the elastic ring 58 to deform through the pressure plate 57, so that the pressure plate 57 slides upward in the groove of the side clamp block 56, and the position of the reinforcement plate is adjusted and positioned by utilizing the inclined surface of the opposite surface of the side clamp block 56 when contacting the reinforcement plate, and an arc groove is opened at the center position of the bottom of the pressure plate 57, an elastic ring 58 is fixedly installed between the pressure plate 57 and the fixed plate 54, and cross plates 59 are fixedly installed on both sides of the pressure plate 57.

[0040] The welding gun mechanism 4 includes a support plate 41, the top of the support plate 41 is fixedly connected to the output end of the first cylinder 3, and a support plate 42 is fixedly installed on the bottom of the support plate 41, and a motor 43 is fixedly installed on the top of the support plate 42. The support plate 41 is driven downward by the first cylinder 3 to move the welding gun mechanism 4 downward as a whole, so that the welding gun 44 reaches the same height as the welding position of the hand lever and the reinforcing plate, and cooperates with the displacement mechanism 2 to perform welding processing. The output end of the motor 43 passes through the support plate 42 and extends to its bottom. The bottom of the support plate 42 is fixedly installed with a cylinder 43. 5. A turntable 46 is rotatably mounted at the bottom of the cylinder 45. The center position of the top of the turntable 46 is fixedly connected to the output end of the motor 43. During welding, the motor 43 drives the turntable 46 to rotate under the restriction of the cylinder 45, and drives the welding gun 44 to rotate through the slot rod 47 to change the welding head angle of the welding gun 44. To change the welding angle, a slot rod 47 is fixedly mounted at the bottom of the turntable 46. A slot is provided at one end of the slot rod 47 away from the turntable 46, and a welding gun 44 is fixedly mounted at the slot of the slot rod 47.

[0041] During use, the worker inserts the door lock handle into the equipment so that the bending position of the handle is inside the pressing mechanism 5 and the two ends of the handle are in the positioning grooves of the positioning block 6. Then the worker puts the reinforcing plate to be welded at the bending position of the handle into the welding position and presses down the contact reinforcing plate through the pressing mechanism 5 so that the reinforcing plate fits tightly with the welding position of the handle. Then, the displacement mechanism 2 cooperates with the welding gun mechanism 4 to drive the hand handle and the reinforcing plate to move synchronously through the displacement mechanism 2, and the contact position with the welding gun mechanism 4 is changed to complete the welding process.

[0042] When fixing the hand lever, the worker puts the hand lever into the equipment so that the two ends of the hand lever are placed in the positioning grooves of the positioning block 6, and then starts the second cylinder 8, so that the second cylinder 8 drives the pressing block 9 to press down, and cooperates with the pressing mechanism 5 to move the pressing block 9 down to contact the two ends of the hand lever. At the same time, the inclined surface of the bottom of the pressing block 9 cooperates with the positioning groove of the positioning block 6. Through the characteristic that the width of the positioning groove gradually decreases from top to bottom, when the hand lever gradually increases the contact pressure with the positioning block 6, the position of the hand lever is adjusted through the adaptation of the pressing block 9 and the positioning groove, so that the top of the hand lever is vertically upward, and the hand lever is at the center position of the positioning block 6.

[0043] In the pressing mechanism 5, when fixing the hand bar, the hand bar is placed on the top of the top plate 52, and the top plate 52 supports the hand bar under the support of the elastic pad 53. When fixing the hand bar, the elastic deformation of the elastic pad 53 is used to provide a buffer space for the hand bar to move downward, and assist in positioning when fixing the hand bar. After the hand bar is fixed, the worker puts the reinforcing plate into the welding position of the hand bar bend, and drives the fixing plate 54 to move downward through the fifth cylinder 55, so that the fixing plate 54 drives the side clamping block 56 to move downward synchronously. In the process of moving downward, the side clamping block 56 is used to move downward. 6 cooperates between them so that the reinforcing plate is located between the side clamping blocks 56, and in the process of moving downward, the pressure plate 57 first contacts the top of the reinforcing plate, and contacts the top of the reinforcing plate through the slot at the top of the reinforcing plate to perform pre-fixation, and then the fixing plate 54 continues to move downward, and in the process of moving downward, the contact pressure compresses the elastic ring 58 to deform through the pressure plate 57, so that the pressure plate 57 slides upward in the groove of the side clamping block 56, and uses the inclined surface of the opposite surface of the side clamping block 56 to adjust and position the reinforcing plate when contacting the reinforcing plate.

[0044] In the welding gun mechanism 4, the support plate 41 is driven downward by the first cylinder 3, so that the welding gun mechanism 4 moves downward as a whole, so that the welding gun 44 reaches the same height of the welding position of the hand lever and the reinforcing plate, and cooperates with the displacement mechanism 2 to perform welding processing. At the same time, during the welding process, the turntable 46 is driven by the motor 43 to rotate under the restriction of the cylinder 45, and the welding gun 44 is driven to rotate by the slot rod 47, so that the angle of the welding head of the welding gun 44 is changed, thereby changing the welding angle.

[0045] In the displacement mechanism 2, the third cylinder 22 cooperates with the fourth cylinder 25, and the third cylinder 22 is used to drive the slide plate 21 to move longitudinally. The fourth cylinder 25 drives the connecting plate 7 through the clamping plate 26, so that the connecting plate 7 slides and adapts with the slide groove of the slide plate 21 through the slider 10, so that the connecting plate 7 moves laterally, and the hand rod and the reinforcing plate move laterally and longitudinally synchronously, and cooperate with the welding gun mechanism 4 to perform welding processing. At the same time, in the process of longitudinal movement of the slide plate 21, the side sliding column 24 is in contact with the frame 1, and the friction resistance is reduced during movement. At the same time, the sliding adaptation of the clamping plate 26 slot and the slide rail 27 is used, and the sliding adaptation of the slider 10 and the slide plate 21 is cooperated to ensure the accuracy during movement.
