Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of excavator component production, in particular to a quick positioning platform for excavator components. BACKGROUND

[0002] An excavator is a kind of earthmoving machinery that uses a bucket to excavate materials higher or lower than the surface of the machine and loads them into transport vehicles or unloads them to a stockpile site. During the production and processing of excavator components, it is often necessary to weld bucket teeth to the bucket. In order to ensure the stability of the bucket and the bucket teeth during welding, the bucket and the bucket teeth need to be positioned.

[0003] Patent No. CN223353366U discloses a positioning mechanism for excavator component production, belonging to the technical field of excavator component production equipment, comprising a bucket and a base, including a support block installed on the base to support the bucket, two mirror image adjustment support devices installed on both sides of the support block to support the two sides of the bucket, and a pressure positioning device installed on the base to press against the inside of the bucket. This patent supports the bucket through the support block, supports the two sides of the bucket through the two adjustment support devices, and presses the inside of the bucket through the pressure positioning device, thereby forming a multi-point positioning effect. The first extension rods of the two adjustment support devices can be extended or retracted to fine-tune the position of the bucket, thereby improving production efficiency and yield.

[0027] Specifically, in the prior art, when welding the bucket and the bucket tooth, the bucket is first fixed, and then the worker manually places the bucket tooth on the bucket for welding. However, under normal circumstances, in order to facilitate excavation, the bucket teeth are equally distributed on the bucket, and during the welding process, it is not easy for the worker to accurately control the distance between the adjacent two bucket teeth, and multiple bucket teeth may not be equally spaced, thereby affecting the subsequent excavation effect of the bucket.

Then, according to the needs, the positioning block 37 on one side is driven to slide on the adjusting rod 33 by the electric push rod 34, so that the multiple positioning blocks 37 are simultaneously moved under the transmission cooperation of the connecting rod 1 and the connecting rod 2, and then the multiple bucket teeth generate equidistant changes until the interval between the adjacent two bucket teeth meets the welding requirements.

[0029] In the embodiment, as shown in the figure, Figures 2-6 The positioning auxiliary assembly is arranged on the upper end face of the positioning table 1. The positioning auxiliary assembly comprises a support plate 6 fixedly connected to one side of the upper end face of the positioning table 1, a turnover plate 8 rotatably arranged on one side of the upper end of the support plate 6, a material shell 1 12 and a material shell 2 13 slidably connected on both sides of the turnover plate 8, the material shell 1 12 and the material shell 2 13 being insertedly and slidably connected, a cover plate 2 slidably connected to one side of the upper end of the turnover plate 8, two guide rods 1 10 slidably connected to one side of the cover plate 2, an installation plate 38 fixedly connected to the end of the guide rod 1 10, a supporting plate 11 rotatably arranged on one side of the lower end of the installation plate 38, a push block 40 slidably connected to the sliding groove of the supporting plate 11, two guide rods 2 16 slidably connected to one side of the bottom of the material shell 1 12 and the material shell 2 13, and a clamping plate 21 fixedly connected to one end of the guide rod 2 16.

[0031] The threaded rod one 20 is rotatably arranged at both ends of the turnover plate 8, the motor three 19 is fixedly connected to one side of the turnover plate 8, the output end of the motor three 19 is fixedly connected to one end of the threaded rod one 20, the air cylinder two 9 is fixedly connected to one side of the upper end face of the cover plate 2, the piston end of the air cylinder two 9 is fixedly connected to one side of the upper end of the mounting plate 38, the mounting plate 38 is fixedly connected to one side of the motor eight 39, the output end of the motor eight 39 is fixedly connected to one side of the supporting plate 11, the threaded rod four 42 is threadedly connected to one side of the push block 40, the threaded rod four 42 is rotatably arranged at both ends of the supporting plate 11, the motor nine 41 is fixedly connected to one end of the supporting plate 11, and the output end of the motor nine 41 is fixedly connected to one end of the threaded rod four 42.

[0032] The air cylinder three 15 is fixedly connected to one side of the bottom of the material shell one 12 and the material shell two 13, and the piston end of the air cylinder three 15 is fixedly connected to one side of the clamping plate 21.

[0034] Specifically, in the above embodiment, although the positioning block 37 can clamp multiple teeth simultaneously, before the positioning block 37 clamps the teeth, the multiple teeth need to be placed at the same angle between the two adjusting rods 33, and the teeth need to be aligned with the positioning block 37. The whole process is not easy to operate by a single person. Moreover, in some cases, the number of teeth to be welded and the number of buckets are large. If the worker frequently places the teeth between the positioning block 37 manually, the labor intensity is high, and the continuous welding efficiency is easily affected by the worker's fatigue. In addition, when a mechanical hand is used to replace the worker to clamp the teeth, if multiple teeth are stacked disorderly, the mechanical hand is also difficult to clamp the teeth one by one accurately, and the visual recognition is difficult. Not only is it easy to fail to clamp, but it is also difficult to accurately adjust the teeth to the appropriate angle, thereby affecting the normal operation of the subsequent welding work.

[0035] Therefore, in order to solve the above problems, the working principle of the embodiment is as follows: Firstly, the present scheme is applied to the same batch of the same specification bucket teeth. Since the bucket teeth are conical, the size of the bucket teeth can be adjusted by rotating the two-way threaded rod 17 driven by the motor 18, so that the shell 12 and the shell 13 slide relative to each other. Since the shell 12 and the shell 13 form a funnel structure by cooperating with each other, the width of the rectangular opening formed by the shell 12 and the shell 13 can be adjusted by moving the shell 12 and the shell 13, and the width of the rectangular opening is smaller than the thickness of the bucket teeth, and the width of the rectangular opening is smaller than the maximum width of the bucket teeth. Then a plurality of bucket teeth are added through the shell 12 and the shell 13, and the bucket teeth will slide to the bottom of the shell 12 and the shell 13 due to gravity. If the tooth base of the bucket teeth is downward, the bucket teeth will not pass through the rectangular opening. Only when the tooth tip of the bucket teeth is downward and the two side slopes of the bucket teeth fit the edge of the rectangular opening, the bucket teeth will pass through the rectangular opening. And when the bucket teeth passing through the rectangular opening drop to a certain height, the bucket teeth will be intercepted because the local width is greater than the width of the rectangular opening. Therefore, all the bucket teeth passing through the rectangular opening will maintain a uniform angle. Then the clamping plates 21 on both sides are driven by the air cylinders 15 to move, so that the clamping plates 21 on both sides fit the part of the bucket teeth passing through the rectangular opening and clamp the bucket teeth. Then the cover plate 2 is driven to descend by rotating the threaded rod 20 driven by the motor 19, and the shell 12 and the shell 13 are covered by the cover plate 2. Then the turnover plate 8 is rotated by 180 degrees by the motor 7, so that all the bucket teeth except the bucket teeth clamped by the clamping plates 21 will fall on the cover plate 2. At this time, the support plate 11 is driven by the air cylinder 9 to approach the clamped bucket teeth, so that the support plate 11 fits the tooth base of the bucket teeth. In order to avoid that part of the bucket teeth falls on the support plate 11 when the turnover plate 8 is turned over, the support plate 11 is rotated by the motor 8 to make the bucket teeth falling on the support plate 11 fall off when the support plate 11 fits the tooth base. When the support plate 11 fits the tooth base of the bucket teeth, the clamping plates 21 are driven away from the bucket teeth. Then the push block 40 is driven to move horizontally by rotating the threaded rod 42 driven by the motor 9, and the bucket teeth supported by the support plate 11 are pushed by the push block 40 until a plurality of bucket teeth fit each other. At this time, the distance between the adjacent two bucket teeth on the support plate 11 is the same. Then the positioning blocks 37 are driven to move again, so that the positioning blocks 37 are located on both sides of the bucket teeth, and the distance between the adjacent two positioning blocks 37 is adjusted so that every two positioning blocks 37 are aligned with a bucket tooth. Then the positioning operation in the above embodiment is repeated, the bucket teeth are clamped by the positioning blocks 37, and then the shell 12 and the shell 13 are driven away from each other, so that the positioning blocks 37 can smoothly take out the bucket teeth from between the shell 12 and the shell 13. Then the distance between the adjacent two bucket teeth is adjusted, and the bucket teeth are placed on the bucket. The number of the bucket teeth clamped by the positioning blocks 37 can be adjusted to meet the subsequent welding requirements. Then the shell 12 and the shell 13 are reset, and the above operation is repeated. The positioning blocks 37 only move along the fixed track each time, so that a plurality of arranged bucket teeth can be accurately clamped.This not only avoids the problem of not easy to operate when manually placing the bucket tooth, but also significantly reduces the labor intensity of workers. In addition, compared with the way of directly using a mechanical hand to grab the bucket tooth from the disordered pile of bucket teeth, the present scheme can uniformly orient and angle the disordered pile of bucket teeth to form an orderly feeding queue. On this basis, the positioning block 37 only needs to run according to a fixed trajectory, so as to stably and accurately complete the clamping, effectively avoiding the problems of clamping failure, identification difficulty and angle adjustment complexity caused by the disorder of the workpiece.

[0036] And since the bucket teeth may not pass through the rectangular opening when they slide to the bottom of the shell one 12 and the shell two 13, the shell one 12 and the shell two 13 can be repeatedly turned over when there is no bucket tooth passing through the rectangular opening, so that the bucket teeth in the inner cavities of the two can continue to roll until the bucket teeth can pass through the rectangular opening, thereby facilitating the smooth progress of the bucket tooth clamping work. And in some cases, the bucket teeth may be stuck at the bottom of the shell one 12 and the shell two 13, causing the bucket teeth to fail to pass through the rectangular opening smoothly, so the slider 22 can be made to slide in the groove of the push plate 14 by the continuous rotation of the crank 47 driven by the motor eleven 46 when the rectangular opening is downward, so that the push plates 14 on both sides reciprocate at the bottom of the shell one 12 and the shell two 13. If the bucket teeth are stuck at the bottom of the shell one 12 and the shell two 13, the push plate 14 will push them, so that they can slide down smoothly, thereby further improving the probability of the bucket teeth passing through the rectangular opening and facilitating subsequent clamping.

[0037] Working principle: first, the bucket is placed on the support table 24, through the two sides of the cylinder 5 drive positioning plate 23 and with the bucket, that is, the bucket can be fixed. Then put multiple bucket teeth between the two adjusting rods 33, and the tooth tip of the bucket tooth is upward, then through the motor ten 43 drive two-way threaded rod two 44 rotation mode, drive two adjusting rods 33 move and close to each other, every two positioning block 37 clamping a bucket tooth, then can clamp multiple bucket teeth. Then according to the need, using electric push rod 34 drive one side of the positioning block 37 on the adjusting rod 33 sliding, then under the transmission cooperation of connecting rod one 35 and connecting rod two 36, make multiple positioning block 37 move at the same time, then multiple bucket teeth produce equidistance change, until the interval of adjacent two bucket teeth meet the welding demand. Then through the motor four 25 drive screw rod two 26 rotation, motor five 27 drive screw rod three 28 rotation, motor six 30 drive gear 29 rotation mode, adjust the position of turnover block 45 in x, y, z axis direction, and use motor seven 32 drive turnover block 45 rotation, can adjust the angle of multiple bucket teeth, make the tooth seat part of multiple bucket teeth fit with the edge of one side of the bucket. At this time, you can use external welding equipment to weld the bucket tooth on the bucket, so as to realize the accurate control of the interval of adjacent two bucket teeth, ensure the subsequent digging effect of the bucket. Because the bucket tooth is tapered, according to the size of the bucket tooth, through the motor two 18 drive two-way threaded rod one 17 rotation, make the shell one 12 and the shell two 13 slide relatively, because the shell one 12 and the shell two 13 cooperate to form a funnel structure, so you can adjust the width of the rectangular opening formed by the shell one 12 and the shell two 13 by moving them, and make the width less than the thickness of the bucket tooth, and the rectangular opening width is less than the maximum width of the bucket tooth. Then put multiple bucket teeth through the shell one 12 and the shell two 13, then the bucket tooth will slide to the bottom of the shell one 12 and the shell two 13 due to gravity, and if the tooth seat part of the bucket tooth is downward, the bucket tooth will not pass through the rectangular opening, only when the tooth tip of the bucket tooth is downward, and the two sides of the bucket tooth are fitted with the edge of the rectangular opening, the bucket tooth will pass through the rectangular opening. And when the bucket tooth passing through the rectangular opening drops to a certain height, the bucket tooth will be intercepted because the local width is greater than the width of the rectangular opening, so all the bucket teeth passing through the rectangular opening will maintain the same angle.Then the two sides of the cylinder three 15 drive the clamping plate 21 to move, the two sides of the clamping plate 21 and the tooth pass through the rectangular opening part of the fit, and the tooth is clamped, then through the motor three 19 drive screw rod one 20 rotating mode drive cover plate 2 down, using cover plate 2 will shell one 12 and shell two 13 above cover, then through the motor one 7 drive turnover plate 8 rotate one hundred and eighty degrees, then in addition to the tooth clamped by the clamping plate 21, the rest of the tooth will fall on the cover plate 2, at this time, using cylinder two 9 drive the approach of the clamping plate 21, make the clamping plate 11 and tooth seat part of the fit, and, in order to avoid the turnover plate 8 turnover, part of the tooth falls on the clamping plate 11, can be in the clamping plate 11 and the tooth seat fit, through the motor eight 39 drive clamping plate 11 rotate, make the tooth fall on the clamping plate 11. When the clamping plate 11 and the tooth seat part of the fit, drive the clamping plate 21 away from the tooth, then through the motor nine 41 drive screw rod four 42 rotating mode drive push block 40 transverse, using push block 40 push the tooth clamped by the clamping plate 11, until the multiple tooth mutually fit, at this time, the interval of the two adjacent tooth on the clamping plate 11 is same. Then again through the drive turnover block 45 moves the way, make multiple positioning block 37 located on both sides of the tooth, and adjust the interval of the adjacent two positioning block 37, so that every two positioning block 37 is aligned with a tooth, then repeat the above positioning operation, using positioning block 37 clamp the tooth, then drive shell one 12 and shell two 13 away from each other, so that the positioning block 37 can smoothly take out the tooth from the shell one 12 and shell two 13, then adjust the interval of the two adjacent tooth, and place the tooth on the bucket, and, the number of tooth clamped by the positioning block 37 can be adjusted to meet the subsequent welding requirements. Then drive shell one 12 and shell two 13 reset, repeat the above operation, then the positioning block 37 only moves along the fixed track each time, can accurately clamp the multiple tooth arranged. This not only avoids the problem that manual placement of tooth is not easy to operate, but also significantly reduces the labor intensity of workers. In addition, compared with the way of directly using the mechanical hand to grab the tooth from the disordered pile of tooth, the present scheme can unify the direction and angle of the disordered pile of tooth, forming an orderly feeding queue. On this basis, the positioning block 37 only needs to run along the fixed track, which can stably and accurately complete the clamping, effectively avoiding the problems of clamping failure, identification difficulty and angle adjustment complexity caused by disordered workpieces of the mechanical hand. And because the tooth may not pass through the rectangular opening when it slides to the bottom of the shell one 12 and shell two 13, the shell one 12 and shell two 13 can be repeatedly turned over when there is no tooth passing through the rectangular opening, so that the tooth in the inner cavity of the shell one 12 and shell two 13 continues to tumble until the tooth can pass through the rectangular opening, thereby facilitating the smooth progress of the tooth clamping work.And in some cases, the tooth may be stuck in the shell 12 and shell 13 bottom, resulting in the tooth can not smoothly through the rectangular opening, so, by the motor eleven 46 driven crank 47 continuous rotation, the slider 22 in the push plate 14 groove sliding, the push plate 14 on both sides in the shell 12 and shell 13 bottom reciprocating sliding, if there is a tooth stuck in the shell 12 and shell 13 bottom, the push plate 14 will push it, make it slide down smoothly, thereby further improving the tooth through the rectangular opening probability, facilitate subsequent clamping.
