Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casters, in particular to a caster bracket positioning device. Background Art
[0002] Casters include movable casters and fixed casters. Movable casters, also known as universal wheels, have a structure that allows 360-degree rotation; fixed casters, also known as fixed casters, have no rotating structure and cannot turn. During the installation and processing of casters, the various accessories of the casters are generally installed and matched manually through tools. The manual installation method has low work efficiency and slow speed, which leads to increased manufacturing costs in the later stage and reduced production efficiency of casters.
[0003] At present, there are automatic assembly equipment for casters on the market, which can complete the manual assembly work by a robot. During automatic assembly, the caster bracket needs to be fixed on the positioning device to facilitate the operation of the robot. Caster brackets of different specifications and shapes need to be equipped with different positioning devices, which increases the cost of the positioning device and is not conducive to the promotion of automatic assembly equipment for casters. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a caster bracket positioning device which is easy to use and has strong versatility.
[0005] To this end, the technical solution of the utility model is: a caster bracket positioning device, including a base, a positioning mechanism and a limiting mechanism, the positioning mechanism includes a positioning chassis and a positioning top plate, the positioning chassis is provided with a mounting groove, the bottom of the positioning top plate is placed in the mounting groove, and the two are fixed by magnetic attraction; the positioning top plate is provided with a plurality of positioning pins, which match the assembly holes on the mounting surface of the caster bracket; the limiting mechanism includes a limiting cylinder and a limiting bracket, and the limiting cylinder drives the limiting bracket to move toward one side of the positioning mechanism.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: two limiting plates are provided on the limiting bracket, and the distance between the two limiting plates matches the caster bracket.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the limit cylinder is fixed on the base through a cylinder mounting plate, and the limit bracket is installed on the cylinder rod of the limit cylinder.
[0008] On the basis of the above solution and as a preferred solution of the above solution: at least one magnet piece is provided in the mounting groove of the positioning chassis.
[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a magnetic attraction piece matching the mounting groove is provided under the positioning top plate, and cooperates with the magnet sheet in the mounting groove.
[0010] The caster bracket includes a top mounting surface and a bottom mounting frame. The mounting surface is provided with assembly holes and can be mounted on the equipment through fasteners. The caster is mounted on the mounting frame through a rotating shaft. The mounting frame generally includes two side surfaces. The mounting frame of the fixed wheel is fixed to the top mounting surface, while the mounting frame of the universal wheel is rotated with the top mounting plate.
[0011] When in use, select the appropriate positioning top plate and limiting bracket according to the specifications of the caster bracket, fix the positioning top plate on the positioning chassis, and fix the two with magnetic attraction; install the limiting bracket on the cylinder rod of the limiting cylinder, and lock and fix the two. The selection basis of the positioning top plate is: the position of the positioning pin on the positioning top plate is opposite to the position of the assembly hole on the mounting surface of the caster bracket, so that the caster bracket can be inverted on the positioning top plate. The selection basis of the limiting bracket is: the spacing between the two limiting plates on the limiting bracket matches the width of the mounting bracket on the caster bracket, so that the limiting plates can be stuck on the outside of the two sides of the mounting bracket, so that the mounting bracket will not rotate, which can better limit the universal wheel.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. A split positioning mechanism is provided on the base. After the positioning chassis is fixed, the positioning top plate can be replaced according to the specifications of the caster bracket. Replacing only the positioning top plate can reduce costs and improve the overall versatility of the positioning mechanism;
[0014] 2. A limit mechanism is set on the base. The limit bracket can also be replaced according to the specifications of the caster bracket, so that the two limit plates on the limit bracket can be stuck on the mounting bracket of the caster bracket, which can effectively prevent the mounting bracket on the universal wheel from rotating and make the installation of the universal wheel more convenient.

[0023] See the accompanying drawings. The caster bracket positioning device described in this embodiment includes a base 1, a positioning mechanism 2 and a limiting mechanism 3. The positioning mechanism 1 includes a positioning chassis 21 and a positioning top plate 22. The positioning chassis 21 is provided with a mounting groove 23. At least one magnet sheet 24 is provided in the mounting groove 23 of the positioning chassis. A magnetic suction piece matching the mounting groove is provided below the positioning top plate 22 to cooperate with the magnet sheet 24 in the mounting groove. The positioning top plate 22 is provided with a plurality of positioning pins 25, which match the assembly holes 43 on the mounting surface of the caster bracket 4. The position of the positioning pins 25 on the positioning top plate 22 is opposite to the position of the assembly holes 43 on the mounting surface 41 of the caster bracket 4, so that the caster bracket 4 can be inverted on the positioning top plate 22.
[0024] The limiting mechanism 3 includes a limiting cylinder 31 and a limiting bracket 32. The limiting cylinder 31 is fixed to the base 1 through a cylinder mounting plate 33, and the limiting bracket 32 is mounted on the cylinder rod of the limiting cylinder 31. The limiting cylinder 31 can drive the limiting bracket 32 to move toward one side of the positioning mechanism 2. The limiting bracket 32 is provided with two limiting plates 34, and the spacing between the two limiting plates 34 matches the caster bracket 4. The spacing between the two limiting plates on the limiting bracket matches the width of the mounting bracket on the caster bracket, so that the limiting plates 34 can be stuck on the outer sides of the two sides of the mounting bracket 42, so that the mounting bracket will not rotate, and the universal wheel can be better limited.
[0025] The caster bracket 4 includes a top mounting surface 41 and a bottom mounting frame 42. The mounting surface 41 is provided with an assembly hole 43, which can be mounted on the equipment through a fastener. The caster is mounted on the mounting frame 42 through a rotating shaft. The mounting frame generally includes two side surfaces. The mounting frame 42 of the fixed wheel is fixed to the top mounting surface 41, while the mounting frame 42 of the universal wheel is rotatably matched with the top mounting surface 41.
[0026] When in use, select the appropriate positioning top plate 22 and limiting bracket 32 according to the specifications of the caster bracket 4, fix the positioning top plate 22 on the positioning chassis 21, and fix the two by magnetic attraction; install the limiting bracket 32 on the cylinder rod of the limiting cylinder 31, and lock and fix the two. Then, install the caster bracket 4 upside down on the positioning top plate 22, so that the positioning pin 24 on the positioning top plate 22 passes through the assembly hole 43 of the caster bracket 4. If it is a universal wheel, adjust the angle of the mounting frame 42, the limiting cylinder 31 starts to ventilate, and the cylinder rod pushes the limiting bracket 32 toward the caster bracket 4, so that the two limiting plates 34 on the limiting bracket 32 are clamped or stuck on the mounting frame 42 of the caster bracket 4, which can effectively prevent the mounting frame on the universal wheel from rotating, making the installation of the universal wheel more convenient.
[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
