Description

Technical Field

[0001] The present application relates to the technical field of transmission belt installation, and in particular to a lightweight transmission belt auxiliary tool and an assembly method. Background Art

[0002] Lightweight transmission belts are used as a transmission medium between the driving wheel and the driven wheel to achieve the function of power transmission. During use, lightweight transmission belts will wear and become abnormally damaged as the length of use increases, and need to be replaced frequently. Therefore, they are consumables. Therefore, in the production process, there is an urgent need for an auxiliary tool that can greatly improve the installation efficiency of lightweight transmission belts.

[0003] Existing patent literature: Patent name: Transmission belt installation tool, document publication number: CN216577658U, discloses a transmission belt installation tool, which includes a mounting body, a transmission part, a push part and a support part. The positioning part at one end of the mounting body can be installed on the rotating shaft of the transmission wheel, and the transmission part is abutted or connected with the transmission wheel hub to achieve synchronous rotation. The push part is responsible for pushing the transmission belt, and the support part is located downstream of the push part, and cooperates with the push part to complete the installation of the transmission belt. This solution simplifies the installation process and improves the installation efficiency. However, this technology has certain application limitations. It is only applicable to the installation of transmission belts for equipment such as small washing machines. In such scenarios, the installation space of the transmission belt is wide and the operation is flexible. However, for the installation of transmission belts for industrial machine tools, the installation space is closed and narrow due to the layout of the machine tools, and the above-mentioned installation tool is not applicable.

[0004] Furthermore, the specifications of machine tool drive belts vary significantly, and there is no unified standard for length, making the aforementioned patented technology difficult to universally adapt. Furthermore, large V-belts are widely used in machine tools, and during actual installation, most horizontal belts must be installed with the belts pointing upwards, which inevitably leads to the problem of belt sagging due to its own weight.

[0005] The traditional method is to install the belt on the drive pulley manually using a crowbar.

[0006] The disadvantages are also very obvious:

[0007] 1. When installing in a closed and narrow space, the gap between the drive pulley and the belt and its surroundings is limited, and the outer edge of the drive pulley is very sharp. It is extremely easy for maintenance personnel to scratch their fingers during the belt installation process, and even their fingers may be clamped by the belt in the gap between the belt and the drive pulley. Once the belt is pried with a crowbar to cause the drive pulley to rotate, the belt will drive the fingers to move, thereby increasing the risk of scratches.

[0008] 2. In a closed and narrow space, due to the lack of visibility, the belt installation process relies entirely on hand feeling and personal experience, which makes the installation process very inconvenient and inefficient. Summary of the Invention

[0009] The purpose of this application is to provide a lightweight transmission belt auxiliary tool and assembly method, which can be used to install lightweight transmission belts in closed and narrow spaces, avoid the problem of the transmission belt sagging due to its own gravity, improve the installation efficiency of the transmission belt, and avoid the installation risks of workers.

[0071] It should be noted in particular that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0072] First, in order to facilitate the embodiments provided by this application, the following description is made of the usage scenarios of this application. Existing machine tools, such as lathes and milling machines. When replacing the transmission belt, since the space for replacing the transmission belt in the machine tool equipment is narrow and closed, the traditional way is to remove the shielding cover plate outside the closed space, adjust the distance between the two transmission wheels by the tensioning device, and then manually turn one of the transmission wheels and install the transmission belt with the help of a crowbar; however, during the actual installation process, since the reserved opening of the closed space is very narrow, the line of sight is blocked. On-site operators usually put one end of the transmission belt on one of the transmission wheels first, and lift the other end of the transmission belt with the action of the crowbar. Then, turn the transmission wheel by hand, and use the crowbar to lift the transmission belt while forcibly embedding the other end of the transmission belt into the other transmission wheel. During this operation, due to limited installation space, the transmission belt is easily deformed under its own gravity and cannot be quickly aligned with the installation position of the transmission wheel, resulting in low installation efficiency. In some cases, manual adjustment of the transmission belt is required. Since the outer edge of the transmission wheel is extremely sharp, when manually adjusting the transmission belt, it is very easy for the transmission belt to be drawn into the gap between the transmission belt and the transmission wheel, thereby scratching the operator. Secondly, the crowbar is easy to scratch the surface of the transmission wheel during use, resulting in rework and increased maintenance costs.

[0073] Based on the above content, there is an urgent need for a lightweight transmission belt auxiliary tool to overcome the above technical problems.

[0074] like Figure 1 As shown, a lightweight transmission belt auxiliary tool includes: a belt support frame 1 and a belt clamping frame 2; the belt support frame 1 is composed of two L-shaped support rods with an opening at one end; wherein the open end of the belt support frame 1 is slidably connected with the corresponding end of the belt clamping frame 2;

[0075] The belt support frame 1 is provided with a hinge portion 3 at the center of one end away from the belt clamping frame 2;

[0076] Belt tightening columns 4 are symmetrically provided on both sides of the hinge portion 3 at the upper end of the belt support frame 1;

[0077] The belt support frame 1 is configured to adjust the size of the opening at one end thereof through the hinge portion 3 to adapt to the size of the transmission belt 9, and tighten one end of the transmission belt 9 through the symmetrically arranged belt tightening columns 4;

[0078] The belt clamping frame 2 has an opening at one end away from the belt supporting frame 1; wherein, the belt guiding columns 5 are symmetrically arranged on both sides of the front upper end of the belt clamping frame 2, and the belt stabilizing columns 6 are symmetrically arranged on both sides of the middle upper end;

[0079] The belt clamping frame 2 is configured to cooperate with the belt tightening column 4, and the transmission belt 9 is stably connected to the upper end of the belt clamping frame 2 through the belt stabilizing column 6 symmetrically arranged in the middle, and the front end of the transmission belt 9 is limited by sliding on the inner wall of the belt guide column 5 through the belt guide column 5 symmetrically arranged in the front and then guided to the outside of the opening of the belt clamping frame 2, so that the protruding part of the front end of the transmission belt 9 forms an arc structure and can be sleeved on the outer periphery of the transmission wheel.

[0080] Specifically, the present application adapts to transmission belts of different specifications by adjusting the overall length of the belt support frame 1 and the belt clamping frame 2, as well as the spacing between the openings at one end of the belt support frame 1 and the belt clamping frame 2. During the installation of the transmission belt, one end of the transmission belt is pre-tightened by the belt tightening column 4 on the belt support frame 1. Then, starting from this, the transmission belt is arranged in sequence along the upper contours of the belt support frame and the belt clamping frame 2. During the arrangement process, the transmission belt is stably supported by the belt stabilizing column 6 of the belt clamping frame 2. The transmission belt from the belt stabilizing column 6 is led out to the front end of the belt clamping frame 2 in a staggered manner through the belt guide column 5, and the front end of the transmission belt is formed into an arc shape so that it can be mounted on the outer periphery of the corresponding transmission wheel. The advantage of this design is that it can be used to install transmission belts in narrow and closed spaces, and the installation efficiency is significantly improved. At the same time, during the installation process, the hands of on-site operators will not be scratched.

[0081] Furthermore, the belt support frame 1 includes: a first L-shaped support rod 11 and a second L-shaped support rod 12 with the same structure; the front ends of the first L-shaped support rod 11 and the second L-shaped support rod 12 are respectively slidably connected to the corresponding ends of the belt clamping frame 2; the rear ends of the first L-shaped support rod 11 and the second L-shaped support rod 12 are rotatably connected through the hinge part 3.

[0082] Among them, the overall shape of the belt support frame 1 is a U-shaped structure with the opening facing one side; and the side wall of the belt support frame 1 away from the opening is arranged into an arc structure; at the same time, the opening spacing size on one side of the belt support frame 1 can be adjusted through the hinge part 3 to adapt to transmission belts of different specifications.

[0083] Furthermore, the hinge portion 3 includes:

[0084] An upper hinge plate 31 is fixedly connected to the rear end of the first L-shaped support rod 11, and a lower hinge plate 32 is fixedly connected to the rear end of the second L-shaped support rod 12; wherein, the upper hinge plate 31 and the lower hinge plate 32 have the same structure and are arranged parallel to each other; the free ends of the upper hinge plate 31 and the lower hinge plate 32 are both arc-shaped, and corresponding positions in the middle of the upper hinge plate 31 and the lower hinge plate 32 are provided with pin holes 34 for the pin shaft 33 to pass through; one end of the pin shaft 33 can be screwed into a locking nut to lock and fix the upper hinge plate 31 and the lower hinge plate 32.

[0085] During installation, the upper hinge plate 31 and the lower hinge plate 32 are fitted together and secured by the pin 33 and the lock nut, thereby securing the first L-shaped support rod 11 and the second L-shaped support rod 12. The advantage of designing the free ends of the upper hinge plate 31 and the lower hinge plate 32 as circular arcs is that they prevent rotational interference between the free ends of the upper hinge plate 31 and the lower hinge plate 32 when the first L-shaped support rod 11 and the second L-shaped support rod 12 rotate, thereby ensuring freedom of movement.

[0086] Furthermore, the fitting surface formed by the upper hinge plate 31 and the lower hinge plate 32 passes through the central axis of the straight sections of the first L-shaped support rod 11 and the second L-shaped support rod 12 .

[0087] It can be understood that during installation, the upper hinge plate 31 and the lower hinge plate 32 fit tightly together, and the positions of the fitting surfaces of the two completely coincide with the central axis of the straight sections of the first L-shaped support rod 11 and the second L-shaped support rod 12, so as to achieve precise connection and positioning, while ensuring that the support rods are evenly stressed and maintain structural stability during rotation.

[0088] Furthermore, the sliding sleeve portions on both sides of the belt support frame 1 and the belt clamping frame 2 are symmetrically provided with bracket locking structures 7;

[0089] The bracket locking structure 7 includes: a plurality of positioning slots 71 arranged at intervals on the upper ends of the front portions of the first L-shaped support rod 11 and the second L-shaped support rod 12, and a locking positioning portion 72 that cooperates with the positioning slots 71 to lock and fix;

[0090] The locking and positioning portion 72 includes: a locking bead 720 that cooperates with the positioning groove 71, a locking column 721 corresponding to the position of the positioning groove 71, a compression spring 722 accommodated in the locking column 721, and a closing cover 723 threadedly connected to the top of the locking column 721;

[0091] The locking column 721 is fixed to the upper rear end of the belt clamping frame 2; the bottom of the compression spring 722 contacts the locking bead 720 and the top contacts the closing cover 723;

[0092] The locking bead 720 is configured to be engaged in the positioning groove 71 under the action of the compression spring 722, so that the belt support frame 1 and the belt clamping frame 2 are fixed in position.

[0093] Specifically, the locking bead 720 is pushed into the positioning groove 71 by the compression spring 722 inside the locking column 721, so that the positions of the belt support frame 1 and the belt clamping frame 2 are fixed.

[0094] Furthermore, the line connecting the contact point between the locking column 721 and the belt clamping frame 2, and the contact point between the belt stabilizing column 6 and the belt clamping frame 2 is parallel to the axis of the straight section of the belt clamping frame 2; the advantages of this design are: the directions of the forces exerted on the belt by the locking column 721 and the belt stabilizing column 6 are consistent, and coordinated with the structural direction of the belt clamping frame 2, which helps to evenly disperse the clamping force on the belt, prevent the belt from being offset or twisted during the clamping process, improve the accuracy and stability of the belt installation and clamping, and solve the problem of position deviation that is prone to occur during the belt installation process.

[0095] The locking post 721 is designed as a belt auxiliary support, used to support the middle area of the transmission belt. The advantage of this design is that, while fully utilizing the locking function of the locking post 721, its design as a belt auxiliary support can effectively offset the sagging or slack in the middle area of the transmission belt caused by its own weight, thereby ensuring that the transmission belt always maintains the appropriate tension at the upper end of the belt clamping frame 2.

[0096] Furthermore, the belt clamping frame 2 includes two symmetrically arranged hollow clamping tubes 21; the rear end of each hollow clamping tube 21 is sleeved on the first L-shaped support rod 11 or the second L-shaped support rod 12, and the front end is bent toward the inside of the opening to form a stabilizing clamping tube 22. The advantages of this design are: it allows the belt to be more evenly stressed during the clamping process, reduces the risk of belt slippage or deviation, and improves the stability and reliability of the clamping.

[0097] The belt stabilizing column 6 is fixed to the middle upper end of the hollow clamping tube 21;

[0098] The belt guide post 5 is fixed to the front upper end of the stabilizing clamping tube 22, and the locking post 721 is fixed to the rear upper end of the stabilizing clamping tube 22. The advantage is that the belt guide post 5 is fixed to the front upper end of the stabilizing clamping tube 22, which can accurately guide the front end of the belt so that it can be smoothly inserted into the transmission wheel, reducing the difficulty of installation.

[0099] The included angle between the axis of the stable clamping tube 22 and the axis of the hollow clamping tube 21 is an obtuse angle, so that the belt is more evenly stressed during the clamping process, reducing the risk of the transmission belt slipping or deflecting, and improving the stability and reliability of the transmission belt clamping.

[0100] Furthermore, a width adjustment structure 8 is provided between the two hollow clamping tubes 21;

[0101] The width adjustment structure 8 is configured to adjust the width of the belt clamping frame 2 according to the diameter of the transmission wheel in cooperation with the belt support frame 1;

[0102] The width adjustment structure 8 includes a first adjustment rod 81 and a second adjustment rod 82 that can slide and contact each other up and down;

[0103] One end of the first adjustment rod 81 and the second adjustment rod 82 are fixed to the corresponding side wall of the hollow clamping tube 21 through a right-angle bracket, and the other ends are in sliding contact with each other;

[0104] A first strip groove 83 is provided in the middle of the length of the first adjustment rod 81; a second strip groove 84 is provided in the middle of the length of the second adjustment rod 82, corresponding to the position of the first strip groove 83; the first strip groove 83 and the second strip groove 84 cooperate to form an adjustable width adjustment path;

[0105] The first adjustment rod 81 is fitted with the inner side of the second adjustment rod 82; wherein the first adjustment rod 81 can be moved from a first position to a second position relative to the second adjustment rod 82 on the fitting surface according to the width adjustment path to complete locking;

[0106] It also includes: a locking rod 85 that can be sequentially inserted into the first strip groove 83 and the second strip groove 84; the first adjustment rod 81 and the second adjustment rod 82 can be locked and fixed by the locking rod 85 cooperating with the nut at its end.

[0107] Specifically, the present application can adjust the width of the belt clamping frame through the width adjustment structure 8, and lock and fix the first adjustment rod 81 and the second adjustment rod 82 in the adjusted position through the cooperation of the locking rod 85 and the nut.

[0108] It can be understood that the width adjustment structure 8 can adapt to the opening spacing of the belt bracket and make corresponding adjustments to adapt to transmission belts of different specifications. At the same time, the width adjustment structure 8 is designed at the rear of the first adjustment rod 81 and the second adjustment rod 82, thereby increasing the stability and firmness of the belt clamping frame as a whole.

[0109] On the other hand, the present application provides a lightweight transmission belt assembly method, which is applied to the lightweight transmission belt auxiliary tool; the method comprises the following steps:

[0110] Step S1: Based on a predetermined belt position and spacing parameter, a transmission belt is arranged on the upper end of the lightweight transmission belt auxiliary tool using a predetermined method; the predetermined belt position includes at least: a belt installation position corresponding to the first transmission wheel 100 and a belt installation position corresponding to the second transmission wheel 200; the spacing parameter includes: the center distance between the first transmission wheel 100 and the second transmission wheel 200;

[0111] Step S2: Moving the lightweight transmission belt auxiliary tool with the transmission belt installed to a preset position on the belt, and moving the lightweight transmission belt auxiliary tool as a whole so that the two ends of the transmission belt are respectively sleeved into the outer peripheral grooves of the first transmission wheel 100 and the second transmission wheel 200;

[0112] Step S3: Based on the tightness of the transmission belts outside the first transmission wheel 100 and the second transmission wheel 200, it is determined whether the lightweight transmission belt auxiliary tool is to be detached from the transmission belts.

[0113] It can be understood that the lightweight transmission belt assembly method provided by the present application is to clamp the transmission belt and arrange it on the upper contour of the lightweight transmission belt auxiliary tool. Then, by moving the lightweight transmission belt auxiliary tool, the transmission belt is placed on the transmission wheels at both ends, such as moving it upward, downward, or to the sides. Then, based on the tightness of the transmission belt, it is determined whether the lightweight transmission belt auxiliary tool should be disengaged from the transmission belt. Then, the lightweight transmission belt auxiliary tool is moved out of the narrow enclosed space as a whole. Compared with the existing technology, the transmission belt replacement efficiency of the present application has been significantly improved, and the operator is prevented from being scratched.

[0114] Furthermore, the method predetermined in step S1 includes:

[0115] Adjusting the external dimension information of the lightweight transmission belt auxiliary tool based on the preset belt position and spacing parameters; the external dimension information includes at least: external contour length information, width information, and the size of the opening at one end of the lightweight transmission belt auxiliary tool;

[0116] Based on the external dimension information, fit the rear end of the transmission belt against the outer side of the belt tightening post 4 on the belt support frame 1 so that the belt installation position corresponding to the first transmission pulley 100 corresponds to the rear end position of the transmission belt, thereby determining the initial position of the transmission belt;

[0117] Based on the initial position of the transmission belt, the rear end of the transmission belt is arranged in sequence from back to front along the upper contours of the belt support frame and the belt clamping frame until the front end of the transmission belt passes through the inner side of the belt guide column 5, so that the protruding position of the front end of the transmission belt corresponds to the belt installation position corresponding to the second transmission wheel.

[0118] Furthermore, the step S3 specifically includes:

[0119] If the transmission belt is in a slack state, the center distance between the first transmission wheel 100 and the second transmission wheel is increased by a tensioning device until the slack state is adjusted to a tensioned state, and the lightweight transmission belt auxiliary tool is separated from the transmission belt;

[0120] For example, static measurement method can be used to determine the slack state of the transmission belt. For example, if the center distance between the two transmission wheels is 500mm and the finger presses the middle of the belt and the amount of sinking exceeds 50mm, it can be determined that the belt is in a slack state.

[0121] If the transmission belt is too tight, the center distance between the first transmission wheel 100 and the second transmission wheel is reduced by a tensioning device until it reaches a normal tension state, and then the transmission belt is separated from the lightweight transmission belt auxiliary tool.

[0122] It can be understood that by pre-adjusting the size of auxiliary tools and standardizing the layout of the transmission belt, the time for repeated adjustments due to inappropriate size and chaotic layout during on-site installation is reduced. Compared with traditional manual operation, the transmission belt can be quickly arranged to the appropriate position, and the front and rear ends of the transmission belt can accurately correspond to the installation position of the transmission wheel, avoiding installation deviation and completing the installation of the transmission belt efficiently and quickly.
