Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, and in particular to an L-shaped multi-position welding displacement device. Background Technology

[0002] In the traditional bulk material handling equipment manufacturing industry, welding has always been an extremely important part, and different welding postures directly affect the quality of the weld. The industry-recognized best welding posture is flat welding. The balance beam of the ship unloader is one of the important components of the ship unloader's traveling mechanism. Patent publication numbers CN222099467U and CN222453859U both describe the balance beam of the ship unloader, so they will not be repeated here.

[0003] Traditionally, balance beam welding involves placing the beam directly on a jig or the ground and welding it manually. This requires workers to move around the beam to perform the welding operation, which is labor-intensive. Furthermore, because the fixed welding method of the balance beam cannot be adjusted, it is impossible to achieve the optimal welding posture, thus the welding quality cannot be fully guaranteed. Summary of the Invention

[0004] To address the problem of inflexible adjustment of the welding posture of balance beams, this invention provides an L-shaped multi-posture welding positioning device. By using a positioner in conjunction with a fixture, the balance beam is fixed on the positioner, enabling flexible adjustment of the balance beam's posture. Simultaneously, it works in conjunction with a welding robot to achieve effective welding of the balance beam.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An L-shaped multi-posture welding positioning device includes a positioner and a fixture controlled by the positioner. The positioner is equipped with the fixture to facilitate control of the fixture to change its posture. The fixture includes a tray, a clamping assembly one, a clamping assembly two, and support members. Multiple support members are evenly arranged in the middle of the tray to facilitate support of a balance beam. The clamping assembly one and the clamping assembly two are respectively arranged on both sides of the tray. The clamping assembly one, the support members, and the clamping assembly two are arranged in a left-center-right sequence. Both clamping components one and two are positive and negative lead screw module structures. Clamping component one has a frustum cylinder slidingly connected to both ends, and the movement of the frustum cylinder is controlled by clamping component one. Clamping component two has a pressure plate slidingly connected to both ends, and the movement of the pressure plate is controlled by clamping component two. The support component cooperates with the load-bearing balance beam. The frustum cylinder of clamping component one clamps one end of the balance beam, and the pressure plate of clamping component two clamps the other end of the balance beam, which facilitates reliable fixation of the balance beam.

[0006] Furthermore, the positioner includes a fixed base, a column, a first rotating component, an L-shaped crossbeam, and a second rotating component. The fixed base is horizontally arranged and fixed to the ground by anchor bolts. The column is installed at one end of the fixed base and is vertically arranged. The top of the column is connected to the L-shaped crossbeam through the first rotating component, which facilitates the rotation of the L-shaped crossbeam. The L-shaped crossbeam is bent into an L shape and is connected to the tray through the second rotating component, which facilitates the rotation of the tray.

[0007] Furthermore, the tray is a rectangular plate with four support members in the middle of the tray. The four support members are arranged in a rectangle. Each support member includes a support column and a rubber pad at the top of the support column to avoid hard contact with the balance beam.

[0008] Furthermore, the clamping assembly one and clamping assembly two are symmetrically arranged on the left and right sides of the support member. Both clamping assembly one and clamping assembly two include positive and negative lead screw modules. The positive and negative lead screw modules include a housing, positive and negative trapezoidal lead screws and nut seats. The outer shell is a rectangular shell, and the positive and negative trapezoidal lead screws are rotatably installed inside the shell. The spirals on both sides of the positive and negative trapezoidal lead screws rotate in opposite directions. The two ends of the positive and negative trapezoidal lead screws extend out of the shell respectively. The two ends of the positive and negative trapezoidal lead screws are four-sided prism structures, which can be easily turned with a wrench. Nut seats are engaged on both sides of the positive and negative trapezoidal lead screws. A sliding plate is provided on the nut seat, and the sliding plate slides along the length of the shell.

[0009] Furthermore, the sliding plate is bent into an "L" shape, and a reinforcing plate is provided at the bend of the sliding plate to improve the structural strength of the sliding plate. The two sliding plates are symmetrically arranged on the positive and negative lead screw modules.

[0010] Furthermore, the clamping assembly one also includes the frustum-shaped cylinder for matching the circular hole of the balance beam. The frustum-shaped cylinder is bolted to the sliding plate, and the two frustum-shaped cylinders are arranged opposite to each other, clamping the circular hole of the balance beam. Furthermore, the clamping assembly two also includes the pressure plate for matching the side of the balance beam. The pressure plate is bolted to the sliding plate, and the pressure plate has a "「" shaped cross-section. The two pressure plates are arranged opposite to each other, and at least two parallel pressure bolts are provided on the horizontal section of the pressure plate. The two pressure plates with pressure bolts cooperate to clamp and press the side of the balance beam.

[0011] The beneficial effects of this utility model through the above technical solution are: The positioner of this invention can drive the fixture to rotate, adjust the position and angle of the fixture, and use the fixture to fix the balance beam, thereby changing the posture of the balance beam. Thus, the positioner can drive the balance beam to adjust its position and angle.

[0012] The fixture of this utility model uses four support columns to support the balance beam, and then clamps it from both ends of the balance beam simultaneously through clamping component one and clamping component two, thereby firmly fixing it on the fixture.

[0013] The clamping assembly one of this utility model has a frustum-shaped clamp that can match the circular hole of the balance beam to achieve clamping of the balance beam's circular hole. The clamping assembly two has a pressure plate as its clamp. The pressure plate facilitates clamping the side of the balance beam, and the pressure bolts on the pressure plate facilitate pressing and fixing the side of the balance beam to prevent the balance beam from falling off.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-5 As shown, an L-shaped multi-posture welding positioning device includes a positioner 1 and a fixture 2 controlled by the positioner 1. The fixture 2 is mounted on the positioner 1, and the positioner 1 can drive the fixture 2 to move. The function of the fixture 2 is to fix the balance beam on the positioner 1, thereby enabling the positioner 1 to control the balance beam to change posture, and thus cooperate with the welding robot to perform welding operations.

[0021] The positioner 1 includes a fixed base 101, a column 102, a first rotating component 103, an L-shaped crossbeam 104, and a second rotating component 105. The fixed base 101 is horizontally arranged and is a straight ladder structure made of steel, fixed to the ground by anchor bolts. A column 102 is installed at one end of the fixed base 101, arranged vertically. The column 102 is connected to the L-shaped crossbeam 104 above the column 102 via the first rotating component 103, thereby causing the L-shaped crossbeam 104 to rotate vertically, bending it into an L-shape. The second rotating component 105 is installed on the horizontal section of the L-shaped crossbeam 104.

[0022] The first rotating component 103 and the second rotating component 105 have the same structure, both being rotary drive structures, which is existing technology. They consist of a slewing bearing and a motor. The inner ring of the slewing bearing is connected to the fixed structure, and the outer ring is connected to the rotating structure. The outer ring of the slewing bearing has teeth. The motor is mounted on the fixed structure, and the motor drives the outer ring of the slewing bearing, thereby rotating the outer ring of the slewing bearing and realizing the rotation of the rotating structure.

[0023] The fixture 2 includes a tray 3, a first clamping assembly 4, a second clamping assembly 5, and a support member 6. The tray 3 is a rectangular plate, and an L-shaped crossbeam 104 is connected to the tray 3 through a second rotating member 105.

Each support member 6 includes a support column 61 and a rubber pad 62 at the top of the support column 61, enabling flexible contact between the support column 61 and the balance beam. Four eye bolts 7 arranged in a rectangle are also provided in the middle of the pallet 3 to facilitate the lifting of the entire fixture 2. The rectangle formed by the eye bolts 7 is larger than the rectangle formed by the support members 6.

[0025] Clamping assembly 1 4 and clamping assembly 2 5 are respectively installed on both sides of the tray 3. Clamping assembly 1 4 and clamping assembly 2 5 are symmetrically arranged on the left and right sides of the support member 6, and clamping assembly 1 4, support member 6 and clamping assembly 2 5 are arranged in the order of left, center and right. Both clamping assembly 1 4 and clamping assembly 2 5 are positive and negative screw module structures, that is, both clamping assembly 1 4 and clamping assembly 2 5 include positive and negative screw modules.

[0026] In this embodiment, the positive and negative lead screw module includes a housing 8, positive and negative trapezoidal lead screws 9, and a nut seat. The housing 8 is a rectangular shell, and the positive and negative trapezoidal lead screws 9 are rotatably mounted inside the housing 8. The spirals on both sides of the positive and negative trapezoidal lead screws 9 have opposite directions of rotation and a self-locking function. The positive and negative trapezoidal lead screws 9 are manually operated. Specifically, both ends of the positive and negative trapezoidal lead screws 9 extend out of the housing 8. The ends of the positive and negative trapezoidal lead screws 9 are quadrangular prism structures. A wrench is used to clamp the ends of the positive and negative trapezoidal lead screws 9, allowing them to be rotated manually.

[0027] The positive and negative trapezoidal lead screw 9 has nut seats on both sides, and sliding plates 10 are set on the nut seats. The sliding plates 10 are bent into an "L" shape and are arranged vertically. Triangular reinforcing plates are set at the bends of the sliding plates 10. The two sliding plates 10 are symmetrically arranged on the positive and negative lead screw module. The height of the sliding plate 10 on clamping assembly 1 4 is greater than the height of the sliding plate 10 on clamping assembly 2 5. The sliding plates 10 slide linearly along the length of the outer shell 8 through the slide rail slider structure. The two sliding plates 10 move closer or further away from each other synchronously.

[0028] Clamping assembly 1 4 has slidably connected frustum cylinders 11 at both ends. The distance between the two frustum cylinders 11 can be synchronously adjusted using a forward and reverse screw module. Specifically, clamping assembly 1 4 also includes frustum cylinders 11 for matching the circular holes of the balance beam; the frustum cylinders 11 are bolted to the sliding plate 10, and the two frustum cylinders 11 are arranged opposite each other, clamping the circular holes of the balance beam.

At least two parallel pressure bolts 13 are provided on the horizontal section of the pressure plates 12, and the two pressure plates 12 with pressure bolts 13 cooperate to clamp and press the sides of the balance beam.

[0029] The principle of the fixture 2 is as follows: the support member 6 cooperates with the load-bearing balance beam, and then the two round frustum cylinders 11 of the clamping component one 4 clamp one end of the balance beam, and the two pressure plates 12 of the clamping component two 5 clamp the other end of the balance beam, thereby fixing the balance beam and locking the balance beam on the positioner 1.

[0030] In order to optimize the product structure, the pallet 3 is designed as a convex-shaped plate body. A protruding portion of the pallet 3 is provided with an auxiliary clamping member 14.
