Description

Technical Field

[0001] The utility model relates to the technical field of crawler beam welding, in particular to a crawler beam welding fixture. Background Art

[0002] The track beam is a commonly used component in mechanical equipment. Its main function is to bear weight and serve as a carrier of the power system and structure. The track beam is mainly made of high-strength steel materials such as steel plates and steel pipes.

[0003] The track beam is mainly welded from three parts: the motor seat at the front end, the U-shaped beam in the middle and the guide seat at the rear end. During the welding process, in order to position and clamp the workpiece and prevent the workpiece from being misplaced during welding, a clamp is usually used to clamp the track beam workpiece, and it can be flipped for welding.

[0004] Through long-term observation, the existing track beam clamps are usually stacked in two groups and fixed in the working area with bolts and other fixings. When clamping a smaller track beam workpiece, there is a certain distance between the two groups of clamps, which makes it difficult for the clamps in the fixed position to clamp and fix the shorter workpiece. Therefore, a track beam welding clamp is proposed to solve the above problem. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model provides a track beam welding fixture.

[0009] Preferably, a collecting plate is provided on the inner wall of the collecting box; the middle part of the collecting plate is recessed; two sets of sliding rods are fixedly connected to the ends of the collecting plate; the sliding rods are slidably arranged on the inner wall of the collecting box; and a pull plate is fixedly connected to the top of the sliding rod.

[0010] Preferably, a second spring is fixedly connected to the end of the rack; and a rubber piece is fixedly connected to the end of the second spring.

[0011] Preferably, a cutter is fixedly connected to the end of the scraper; and the middle portion of the cutter is in contact with the storage plate.

The crawler beam welding fixture described in the utility model can improve the cleanliness of the middle part of the storage plate by providing a contact scraper on the top of the storage plate, and reduce the problem that the high-temperature welding slag directly adheres to the middle part of the storage plate when falling downward, resulting in the need for subsequent staff to clean the surface of the storage plate with the help of a large working area. The welding slag can be collected by combining the inclined scraper and the hollow collection box, reducing the need for secondary cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , 2As shown in , 4 and 6, a crawler beam welding fixture comprises a base 1; two groups of slide grooves 16 are opened on the top of the base 1; two groups of fixture bodies 11 are installed on the top of the base 1; the fixture body 11 is slidingly arranged in the middle of the slide groove 16; a rack 12 is fixedly connected to the middle of the fixture body 11; a bracket 13 is fixedly connected to the top of the base 1; a double-axis motor 14 is installed on the top of the bracket 13; a tooth block 15 is fixedly connected to the bottom output end of the double-axis motor 14; the tooth block 15 and the two groups of racks 12 are meshed with each other; a storage plate 17 is fixedly connected to the top of the bracket 13; the middle part of the storage plate 17 is arc-shaped; when working, the staff needs to install the base 1 in the working area, so that when the fixture body 11 is clamping and fixing a shorter workpiece, the staff can turn on the switch of the double-axis motor 14 set on the top of the bracket 13, so that the double-axis motor 14 set at the bottom output end will drive the double-axis motor 14 to rotate after being energized Because the tooth block 15 and the two sets of racks 12 are meshed with each other, when the tooth block 15 rotates, the two sets of clamp bodies 11 will move closer synchronously under the pulling force of the rack 12, and the distance between the two sets of clamp bodies 11 will be shortened. Then the workpiece to be welded can be fixed on the clamp body 11. At this time, the workpiece in the middle of the clamp body 11 can be welded, and the arc-shaped storage plate 17 can be used to collect some of the residues produced after welding. This step, combined with the two sets of clamp bodies 11 set relatively slidingly, can improve the flexibility when clamping the workpiece, and reduce the problem that the original two sets of clamp bodies 11 are fixed on the top of the base 1, which makes it difficult to clamp and fix shorter workpieces. Combined with the arc-shaped storage plate 17, it can reduce the problem that during the welding process of the workpiece, some welding slag directly falls on the tooth block 15 or the inner groove of the rack 12, causing the two to jam when they are meshing.

[0026] like Figure 2 , 3As shown in Figure 6, the top output end of the dual-axis motor 14 is fixedly connected to a rotating shaft 2; the rotating shaft 2 is rotatably arranged in the middle of the storage plate 17; a connecting rod 21 is fixedly connected to the middle of the rotating shaft 2; a fixed plate 22 is fixedly connected to the end of the connecting rod 21; two groups of scrapers 23 are fixedly connected to the middle of the fixed plate 22; the middle of the scraper 23 is inclined; the end of the scraper 23 is fixedly connected to a collecting box 24; the collecting box 24 is hollow; when working, the rotating shaft 2 is arranged at the top output end of the dual-axis motor 14, so that when the dual-axis motor 14 resets the position of the two groups of clamp bodies 11, its output end will synchronously drive the rotating shaft 2 to rotate, because the rotating shaft 2 and the connecting rod 21 are fixedly connected, so that the two groups of inclined scrapers 23 will rotate at the inner wall of the storage plate 17 and transfer the welding slag accumulated on the inner wall of the storage plate 17 to the arc-shaped scraper 23. At the same time, the welding slag separated from the middle part of the storage plate 17 will roll downward in the middle of the scraper 23 and be collected in the hollow collection box 24. This step can improve the cleanliness of the middle part of the storage plate 17 by providing a contact scraper 23 on the top of the storage plate 17, and reduce the problem that the high-temperature welding slag directly adheres to the middle part of the storage plate 17 when falling downward, resulting in the need for subsequent staff to clean the surface of the storage plate 17 with the help of a large working area. The welding slag can be collected in conjunction with the inclined scraper 23 and the hollow collection box 24, reducing the need for secondary cleaning.

[0027] like Figure 6 As shown, the end of the fixing plate 22 is fixedly connected to a fixing piece 3; two groups of first springs 31 are fixedly connected to the middle of the fixing piece 3; a counterweight ball 32 is fixedly connected to the end of the first spring 31; a baffle rod 33 is fixedly connected to the inner wall of the receiving plate 17; during operation, by arranging a counterweight ball 32 at the end of the fixing plate 22, the fixing plate 22 rotates on the top of the receiving plate 17, and the middle of the baffle rod 33 will contact the two groups of counterweight balls 32 in sequence. Then, when the middle of the counterweight ball 32 is squeezed, the middle of the first spring 31 will be squeezed and deformed. At this time, the reaction force of the first spring 31 after resetting can be used to make the two groups of counterweight balls 32 collide with each other. This step cooperates with the force generated after the middle of the two groups of counterweight balls 32 collide, which can reduce the problem that part of the cleaned welding slag accumulates in the middle of the counterweight ball 32, making it difficult to clean the welding slag by relying on the inclined scraper 23, thereby improving the accuracy of the scraper 23 in cleaning the welding slag later.

[0028] like Figure 3 and 5As shown, the inner wall of the collection box 24 is provided with a collecting plate 4; the middle part of the collecting plate 4 is recessed; two sets of sliding rods 41 are fixedly connected to the end of the collecting plate 4; the sliding rods 41 are slidingly arranged on the inner wall of the collection box 24; a pulling plate 42 is fixedly connected to the top of the sliding rod 41; during operation, a sliding rod 41 that can be slidably arranged is arranged inside the collection box 24, so that part of the welding slag transferred to the inner wall of the collection box 24 is transferred to the middle part of the collecting plate 4, so that when the staff needs to clean the welding slag, the staff can pull the middle part of the pulling plate 42 and take out the collecting plate 4. This step, combined with the recessed collecting plate 4, can reduce the problem that it is difficult for the staff to clean the welding slag accumulated at the edge of the collection box 24, and reduce the problem that part of the welding slag accumulates in the connection gap of the collection box 24, which causes trouble for the subsequent staff to clean the middle part of the collection box 24.

[0029] like Figure 4 As shown, the end of the rack 12 is fixedly connected to a second spring 5; the end of the second spring 5 is fixedly connected to a rubber member 51; during operation, by arranging the second spring 5 at the end of the rack 12, when the two groups of clamp bodies 11 gradually approach each other, the middle of the rubber member 51 will contact the middle of the clamp body 11, and squeeze the middle of the second spring 5 during the contact process. This step, combined with the rubber member 51 made of soft material, can reduce the problem of large wear on the surfaces of the two after the end of the rack 12 directly contacts the middle of the clamp body 11. At the same time, combined with the second spring 5 with elastic force, the rubber member 51 can be reset when the clamp body 11 and the rack 12 move away from each other.

[0030] like Figure 6 As shown, a cutter 6 is fixedly connected to the end of the scraper 23; the middle part of the cutter 6 is arranged in contact with the receiving plate 17; during operation, by arranging the cutter 6 at the end of the scraper 23, when the scraper 23 moves on the top of the receiving plate 17, the cutter 6 will scrape off part of the welding slag that is relatively firm in the middle part of the receiving plate 17. This step is combined with some large pieces of welding slag that are relatively firm, resulting in the problem of edge collapse after the end of the scraper 23 directly contacts the welding slag.

[0031] like Figure 5 As shown, a plurality of friction grooves 7 are provided in the middle of the pull plate 42. During operation, by providing a concave friction groove 7 in the middle of the pull plate 42, when the staff member pulls the middle of the pull plate 42, his hand will directly contact the friction groove 7. This step, combined with the friction groove 7, can reduce the problem of slippage between the staff member's hand and the pull plate 42, and improve the friction force when the staff member's hand contacts the middle of the pull plate 42.

[0032] Working principle: by installing the base 1 in the working area, when the clamp body 11 clamps and fixes a shorter workpiece, the staff can turn on the switch of the double-axis motor 14 set on the top of the bracket 13, so that the double-axis motor 14 will drive the double-axis motor 14 set at the bottom output end to rotate after being energized. Because the gear block 15 and the two sets of racks 12 are meshed with each other, when the gear block 15 rotates, the two sets of clamp bodies 11 will move closer synchronously under the action of the pulling force of the racks 12, and the distance between the two sets of clamp bodies 11 will be shortened. Then, the workpiece to be welded can be fixed on the clamp body 11, and the clamp body 11 can be The arc-shaped receiving plate 17 can be used to collect the slag produced after some welding. The rotating shaft 2 is provided at the output end of the top of the double-axis motor 14, so that when the double-axis motor 14 resets the position of the two sets of clamp bodies 11, its output end will synchronously drive the rotating shaft 2 to rotate. Since the rotating shaft 2 and the connecting rod 21 are fixedly connected, the two sets of inclined scrapers 23 will rotate at the inner wall of the receiving plate 17, and transfer the welding slag accumulated on the inner wall of the receiving plate 17 to the arc-shaped scraper 23. At the same time, the welding slag separated from the middle part of the receiving plate 17 will roll downward in the middle of the scraper 23 and be collected in the hollow The collecting box 24 is provided with a counterweight ball 32 at the end of the fixing plate 22, so that when the fixing plate 22 rotates on the top of the receiving plate 17, the middle part of the blocking rod 33 will contact the two groups of counterweight balls 32 in sequence, and then when the middle part of the counterweight ball 32 is squeezed, the middle part of the first spring 31 will be squeezed and deformed. At this time, the reaction force after the first spring 31 is reset can be used to make the two groups of counterweight balls 32 collide with each other, and a slidable sliding rod 41 is provided inside the collecting box 24, so that part of the welding slag transferred to the inner wall of the collecting box 24 is transferred to the middle of the collecting plate 4, so that when the staff needs to clean the welding slag, the staff can pull Pull the middle of the plate 42 and take out the collecting plate 4. By providing a second spring 5 at the end of the rack 12, when the two groups of clamp bodies 11 gradually approach each other, the middle of the rubber member 51 will contact the middle of the clamp body 11 and squeeze the middle of the second spring 5 during the contact process. By providing a cutter 6 at the end of the scraper 23, when the scraper 23 moves on the top of the storage plate 17, the cutter 6 will scrape off part of the welding slag that is relatively firm welded to the middle of the storage plate 17. By providing a recessed friction pattern 7 in the middle of the pull plate 42, when the staff pulls the middle of the pull plate 42, their hands will directly contact the friction pattern 7.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
