Description

TECHNICAL FIELD

[0001] The utility model relates to a fixing mechanism, more particularly to a batch hub fixing mechanism. BACKGROUND

[0002] Because the hub is a rigid structure with heavy weight, the use of a conveying belt for batch transportation is prone to damage the conveying belt, and therefore is not suitable for conveying on a belt conveyor. In the prior art, a drum conveyor is usually used to batch convey the hub, and the hub is laid down to be placed flat on the conveyor, at which time the axis of the hub is perpendicular to the axis of the roller of the conveyor. However, because the direction of the hub arrangement is generally parallel to the axis of the roller of the conveyor, at this time the roller and the bottom of the hub are in line contact, and when the conveyor stops conveying, the hub is prone to move in the conveying direction. SUMMARY

[0003] The utility model provides a batch hub fixing mechanism, which can fix the roller on the drum conveyor.

[0004] The above object is achieved by the following technical solutions.

[0005] A batch hub fixing mechanism comprises a roller mechanism and a lifting mechanism, the roller mechanism comprises a roller, an end of the roller along an axis is rotationally connected with a base, the roller mechanism is symmetrically provided with two, the lifting mechanism is used for controlling lifting of all the bases, the two rollers are synchronously close when being lifted, and the two rollers are synchronously away when being lowered.

[0006] The base comprises a bearing and a seat body, the end of the roller is fixed to an inner ring of the bearing, and an outer ring of the bearing is fixed in the seat body.

[0007] The axial location of the roller and the base is achieved by a snap spring.

[0008] One lifting mechanism is used for one roller mechanism, the lifting mechanism is fixed with the base, and the action track of the lifting mechanism is parallel to the action track of the roller.

[0009] The lifting mechanism is a hydraulic cylinder or an electric telescopic cylinder, and a telescopic end of the lifting mechanism is fixed with the base.

[0010] Each roller mechanism further comprises a limiting piece fixed with a lower part of the base, the limiting piece is obliquely and slidingly connected in the base, the limiting piece is a straight rod structure, the limiting piece on the left side is low on the left side and high on the right side, the limiting piece on the right side is high on the left side and low on the right side, and the number of the lifting mechanisms is one for driving lifting of all the limiting pieces.

[0011] Further comprising a bracket, the bottom of all the limiting pieces is in contact with the top of the bracket, and the lifting mechanism drives lifting of the bracket.

[0012] The lifting mechanism is a scissor lifting mechanism, a hydraulic cylinder or an electric telescopic cylinder, the top of the lifting mechanism is connected to the bottom of the bracket, and the lifting mechanism can keep the bracket horizontal.

[0013] The lifting mechanism is an electric telescopic cylinder, and the telescopic end of the lifting mechanism is fixedly connected to the lower end of the bracket.

[0014] The bottom of the limiting piece is rotationally connected with a wheel, and the wheel is in contact with the bracket to realize rolling friction.

[0015] The batch hub fixing mechanism has the advantages that:

[0016] The batch hub fixing mechanism can be used in cooperation with a roller conveyor, the initial spacing of the two rollers at the lowest position needs to be greater than the diameter of the hub, so that the two rollers can be raised and approached at the same time, the freedom of a row of hubs in the forward and reverse directions during transportation can be limited between the two rollers, the row of hubs can be placed on the rollers of the roller conveyor at this time, and the row of hubs is aligned and corrected, and the problem that the hub is not fixed when the traditional roller conveyor stops is overcome.

[0026] A batch wheel hub fixing mechanism, comprising a roller mechanism and a base frame 1 for supporting the roller mechanism. Wherein the roller mechanism comprises a roller 2, the front and rear ends of the roller 2 are respectively rotatably connected with a base 3, the base 3 can be a bearing with a seat, and the roller 2 is respectively fitted in the inner ring of the bearing of the two bearings with a seat. The lower part of each base 3 is fixedly connected with a limiting piece 4. If the limiting piece 4 on each base 3 is a cylinder, the number of the limiting piece 4 is at least two. The limiting piece 4 needs to be inclinedly arranged, so that the limiting piece 4 is inserted into the hole on the base frame 1, the axis of the limiting piece 4 coincides with the axis of the hole on the base frame 1, the limiting piece 4 is achieved to be inclinedly slid along the base frame 1, and the base frame 1 is fixed on the ground.

[0027] The roller mechanism needs to be arranged in a mirror image to be used. Specifically, the left low right high limiting piece 4 on the left side and the left high right low limiting piece 4 on the right side are arranged, so that the axes of the two limiting pieces 4 are located on a virtual inverted V shape, then a bracket 5 is arranged below the limiting piece 4, the bracket 5 is lifted by a lifting mechanism 6, thereby controlling the height of the bracket 5, the bracket 5 lifts the bottom of all the limiting pieces 4, thereby controlling the height of the roller 2 by changing the height of the limiting piece 4.

[0028] Reference Figures 7 to 9 The batch wheel hub fixing mechanism is used in combination with a roller conveyor when arranged. The initial spacing of the two rollers 2 at the lowest position needs to be greater than the diameter of the wheel hub, so that the two rollers 2 can be respectively located on the left and right sides of the wheel hub. The axes of the two rollers 2 are arranged in parallel with the axes of the rollers on the roller conveyor, and the top parts of the two rollers 2 are tangent to the top parts of the rollers on the other roller conveyors on the same plane when the top parts of the two rollers 2 are at the lowest position. There are at least two rollers between the two rollers 2 on the roller conveyor. In this way, when the wheel hub is located between the two rollers 2, the contact mode between the bottom of the wheel hub and the rollers on the roller conveyor is two-line contact, which can make the wheel hub flat.

[0029] Because the hole on the left base frame 1 is left low right high, and the hole on the right base frame 1 is left high right low, when the bracket 5 is raised, the left limiting piece 4 on the left side is pushed to be raised and at the same time is pushed to be closer to the right, and at the same time the right limiting piece 4 on the right side is pushed to be raised and at the same time is pushed to be closer to the left, so that the two rollers 2 gradually approach the wheel hub while contacting the left and right sides of the wheel hub, thereby limiting the freedom of the wheel hub in the forward and backward directions along the roller conveyor when the wheel hub is on the roller conveyor. Generally, the limitation of the freedom of the wheel hub is performed when the roller conveyor stops working. If the roller conveyor is in a transportation state, the raising of the two rollers 2 mainly plays a role in intercepting the transported articles on the roller conveyor, or lifting the articles on the two rollers 2, so that the articles stop transportation when the roller is running.

[0030] The angle between the inclined moving track line of the roller 2 and the mirror image plane of the two roller mechanisms is generally 10° to 60°, which depends on the distance between the two adjacent rollers on the roller conveyor. The smaller the distance between the two rollers, the smaller the angle, so that the transverse extension of the roller mechanism is reduced, and the roller 2 does not interfere with the roller after being raised, avoiding the collision between the roller 2 and the roller. The angle between the axis of the hole on the base 3 and the mirror image plane is denoted as ∠S1, and the angle between the inclined moving track line of the roller 2 and the mirror image plane is denoted as ∠S2, ∠S1 = ∠S2.

[0031] The lifting mechanism 6 is preferably a scissor lifting mechanism, a hydraulic cylinder or an electric telescopic cylinder. The electric telescopic cylinder is preferred, and the electric telescopic cylinder can be selected according to the height of the conveying roller of the roller conveyor. When the minimum height of the electric telescopic cylinder is reached, i.e. the stroke is reduced to the shortest, the total height of the batch hub fixing mechanism does not exceed the height of the roller of the roller conveyor. Then the stroke of the electric telescopic cylinder is adjusted, so that the initial position of the roller 2 is the same height as the roller. For example, the IMB series servo electric cylinder of Limtec, model IMB10, IMB20, …, IMB80, with a stroke of 500mm-2500mm, can be fixed to the bottom of the lifting mechanism 6 on the concrete, metal or wooden base, and the telescopic end of the top of the lifting mechanism 6 is fixed to the bottom of the bracket 5. The fixing method is not limited to the conventional bolt connection, structural adhesive connection and the connection method provided in the product specification of the specific telescopic cylinder. Preferably, the bottom of the limiting piece 4 can be in rolling friction with the bracket 5, for example, the wheel 7 is rotatably connected to the bottom of the limiting piece 4, and the wheel 7 is in contact with the bracket 5 to realize rolling friction.
