DETAILED DESCRIPTION
[0020] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:
[0021] like Figure 1-3 As shown, a positioning device for feeding a gear ring is arranged at the right end of a conveyor line 1 that transports from left to right, and is mainly composed of a positioning platform 2, a limit block 3, a clamping adjustment assembly, a support frame 4 and a tilt adjustment assembly. Among them, limit blocks 3 for limiting the position of the gear ring are relatively arranged in the front and back of the middle part of the positioning platform 2, and the two limit blocks 3 are both arranged on the clamping adjustment assembly, and the clamping adjustment assembly is arranged on the positioning platform 2, and the clamping adjustment assembly can adjust the distance between the two limit blocks 3, so that the limit blocks can clamp the gear ring and be suitable for gear rings of different specifications. The positioning platform 2 is arranged on the support frame 4 through the tilt adjustment assembly, and the tilt adjustment assembly is used to adjust the inclination of the positioning platform 2, so that the gear ring can slide from the left end of the positioning platform to between the two limit blocks under the action of gravity.
[0022] In order to adjust the distance between the two limit blocks, one can be kept stationary while the other moves, or the two limit blocks can move toward or in the opposite direction while the center remains unchanged. When the two move toward or in the opposite direction, the clamping adjustment assembly includes an adjustment motor 5 arranged below the positioning platform 2, and the adjustment motor 5 is provided with a rotating screw 7 extending forward and backward through a transmission assembly 6, and the two ends of the rotating screw 7 are rotatably arranged below the positioning platform 2 through a screw seat 8, and rotating nuts 9 are screwed at the front and rear ends of the rotating screw 7, and the moving directions of the two rotating nuts 9 are opposite, and each rotating nut 9 is connected to the limit block 3 through a corresponding connecting block 10. The transmission assembly is a gear box structure in the prior art.
[0023] To ensure the stability of the movement of the limit block, it is best to provide a guide rail on the bottom surface of the positioning platform, and the connecting block is configured to include a horizontal connecting block and two vertical connecting blocks spaced apart on the left and right, the horizontal connecting block is used to connect the two vertical connecting blocks, the two vertical connecting blocks extend up and down and are used to connect with the limit block, and a slider is provided between the horizontal connecting block and the guide rail.
[0024] The tilt adjustment assembly includes a tilt cylinder 12 whose lower end is hinged on a cylinder seat 11, and the output end of the tilt cylinder 12 is hinged on the lower left side of the positioning platform 2. Correspondingly, the left side of the positioning platform 2 is set on the support frame 4 through a telescopic column 13, and the right side of the positioning platform 2 is set on the support frame 4 through a hinge seat 14, that is, the right end of the positioning platform is hinged to the support frame.
[0025] To simplify the structure, the support frame 4 is configured as four support columns distributed in a rectangular shape.
[0026] In order to enable the two limit blocks to clamp the gear ring, the opposite surfaces of the two limit blocks 3 are set as limit surfaces for limiting the further movement of the gear ring, and the limit surfaces are set to be arc-shaped or V-shaped.
[0027] In order to facilitate confirmation that the gear ring has been clamped, a detection sensor 15 for detecting whether it is in contact with the gear ring is provided in the middle of at least one limit block 3 .
[0028] In order to prevent the gear ring from moving in transition, a buffer limit assembly for limiting the distance the gear ring moves to the right is provided at the right end of the positioning platform 2, and the buffer limit assembly includes two buffers 16 spaced apart in front and back and an auxiliary stop block 17 provided between the two buffers.
[0029] In order to facilitate the gear ring to smoothly enter the two limit blocks 3 on the conveyor line, a guide block 18 is provided on the two limit blocks 3 for guiding the gear ring when sliding in and extending to the upper right end of the conveyor belt. The inner sides of the two guide blocks 18 are provided with guide slopes, and the two guide slopes are arranged in an eight-shaped shape facing right. Preferably, the distance between the right ends of the two guide slopes is smaller than the distance between the two limit blocks, so that when the limit blocks are in the clamping process, the next gear ring cannot move between the two limit blocks, thereby ensuring that there is only one gear ring between the two limit blocks.
[0030] In order to further ensure that only one gear ring enters between the two limit blocks, a blocking component is also provided to ensure that only one gear ring enters. Figure 4As shown, the blocking assembly includes a trigger member extending left and right, and the middle part of the trigger member is hinged on the blocking seat, and a trigger groove for the right end of the trigger member to extend out is arranged on the left side of the positioning platform located at the limit block, and the front side of the right end of the trigger member is arranged as an inclined trigger surface. A blocking member is hinged on the left side of the trigger member, and the upper side of the blocking member can slide up and down on the positioning platform. When the left end of the positioning platform is lifted by the lifting assembly, the uppermost end of the blocking member is located in the sliding groove on the positioning platform for the blocking member to slide up and down. When the gear ring moves between the two limit blocks under the action of gravity, the gear ring will move the right end of the trigger member downward along the trigger surface, so that the blocking member located at the left end of the trigger member will move upward, thereby blocking the subsequent gear ring from moving to the right. Since the gear ring is a ring structure, in order to ensure that the front side of the same gear ring does not affect the movement of the rear side of the gear ring after being triggered, it is best that the distance between the blocking member and the right end of the trigger member is slightly greater than the thickness of the gear ring, so that only when the rear side of the previous gear ring is triggered can it be used to block the entry of the next gear ring.
[0031] Preferably, the conveyor line 1 adopts a roller conveyor line with the left end higher than the right end, so that the gear ring can move under the action of gravity, thereby reducing energy consumption. The inner side of the guide ramp is equipped with a buffer pad to prevent the gear ring from directly hitting.
[0032] In the initial state, the two limit blocks are separated, and the tilt cylinder lifts the left end of the positioning platform. Under the action of gravity, the gear ring moves along the guide slope from the conveyor line toward between the two limit blocks. When the gear ring has completely passed the guide slope, the two limit blocks start to move toward each other under the action of the adjusting motor until the detection sensor detects a signal and stops moving. At this time, the gear ring is just clamped, and then the tilt cylinder is retracted to return the positioning platform to a horizontal position.
