Description

Technical Field

[0001] This utility model relates to the field of belt conveyor idler manufacturing, specifically to a belt conveyor idler assembly fixture. Background Technology

[0002] A belt conveyor is a continuous conveying device that uses cotton canvas, nylon, polyester canvas, or steel cord conveyor belts as traction components. Belt conveyors are mainly used for conveying various bulk materials and packaged goods, and are widely used in industries such as coal, metallurgy, mining, ports, chemicals, light industry, petroleum, and machinery. Belt conveyors feature large carrying capacity, high climbing ability, low operating costs, and convenient use and maintenance, facilitating automated control of transportation systems.

[0003] Idler rollers are a key component of belt conveyors, supporting the conveyor belt and materials, and serving as the primary load-bearing equipment. The conveyor belt accounts for over 25% of the total conveyor cost. During operation, idler rollers operate flexibly and reliably, effectively reducing friction between the conveyor belt and the rollers. Therefore, the quality of idler roller bearing installation directly affects the lifespan of the conveyor belt, and consequently, the conveyor's operating costs.

[0004] The bearings of the idler roller and the rotating shaft of the idler roller need to be properly fitted during assembly. However, during the small-batch trial production of the idler roller, due to the lack of special production tools, the bearings need to be manually hammered into the bearing housing. This often results in bearing deformation due to uneven assembly force, which affects the flexibility of the idler roller rotation. Utility Model Content

[0005] The purpose of this utility model is to provide a belt conveyor idler assembly fixture, which includes an annular top pressure device that can apply pressure to the end face of the bearing, thereby achieving uniform force on the bearing and avoiding the problem of bearing deformation during the idler production process.

[0006] To achieve the above objectives, this utility model provides a belt conveyor idler assembly fixture, which includes a fixture body, an idler bracket, a fixed base fixedly connected to the fixture body, and a pressure device disposed opposite to the fixed base. One end of the pressure device facing the fixed base is connected to a top presser, and the pressure device can drive the top presser to move toward the fixed base.

[0007] The working surface of the top press is set as an annular shape, the top press is coaxially arranged with the bearing, and the working surface of the top press mates with the end face of the bearing.

[0008] The idler roller is placed on the idler roller bracket, with the end of the idler roller away from the top press abutting against the working surface of the fixed base.

[0009] Preferably, one side of the fixed base facing the carrier roller is provided with an extension hole, and the shaft of the carrier roller extends into the extension hole.

[0010] Preferably, the carrier roller support is provided with an arc-shaped supporting surface which cooperates with the side surface of the carrier roller to support the carrier roller.

[0011] Preferably, the carrier roller support is slidably connected with the tool body.

[0012] Preferably, the pressure device is slidably connected with the tool body.

[0013] Preferably, the height of the arc-shaped supporting surface of the carrier roller support is adjustable.

[0014] Preferably, the belt conveyor carrier roller assembly tool further comprises a gasket which is arranged between the shaft and the bottom surface of the extension hole.

[0015] Preferably, the gasket is magnetic.

[0016] Preferably, the belt conveyor carrier roller assembly tool further comprises a calibration device which can identify the axis of the pressure device, and the calibration device is fixedly connected with the pressure device.

[0017] Preferably, the belt conveyor carrier roller assembly tool further comprises a center finder which can measure the center of the end surface of the shaft.

[0018] According to the above technical solution, when the carrier roller is placed on the carrier roller support and the pressure device is used to apply a pushing force to the pressing device, the pressing device will push the bearing end surface of the carrier roller, so that the bearing moves towards the bearing seat until the bearing is installed on the bearing seat.

[0019] After the carrier roller is placed on the carrier roller support, one end of the carrier roller abuts against the fixed base, and the other end is subjected to the pushing force of the pressure device, and the pushing force of the pressure device acts on the end surface of the bearing through the pressing device, so that the bearing moves towards the bearing seat under the pressure, thereby realizing the installation of the carrier roller bearing.

[0020] Since the working surface of the pressing device is annular, the annular working surface can cooperate with the end surface of the bearing, so that the pressing device can uniformly apply pressure to the entire end surface of the bearing, thereby achieving the purpose of reliably pushing the bearing into the bearing seat, effectively avoiding the problem of bearing deformation caused by uneven assembly force, and thereby ensuring the flexibility of the rotation of the carrier roller.

[0021] Other features and advantages of the present application will be described in detail in the following specific embodiment part. BRIEF DESCRIPTION OF DRAWINGS

[0037] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0038] In the present application, unless otherwise stated, the orientation words contained in the terms such as "face, one end, opposite, coaxial, bottom" only represent the orientation of the term in the normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0039] Reference should be made to Figures 1-2The belt conveyor roller assembly tool comprises a tool body 1, a roller support 2, a fixed base 3 fixedly connected with the tool body 1, a pressure device 4 arranged opposite to the fixed base 3, and a pressing device 5 connected to one end of the pressure device 4 facing the fixed base 3, wherein the pressure device 4 is capable of driving the pressing device 5 to move towards the fixed base 3.

[0040] The working surface of the pressing device 5 is annular, the pressing device 5 is coaxially arranged with the bearing 101, and the working surface of the pressing device 5 is matched with the end surface of the bearing 101.

[0041] The roller is placed on the roller support 2, and one end of the roller away from the pressing device 5 abuts against the working surface of the fixed base 3.

[0042] Through the implementation of the above technical scheme, the roller is placed on the roller support 2, and the pressure device 4 is used to apply a pushing force to the pressing device 5, so that the pressing device 5 pushes the end surface of the bearing 101 of the roller, and the bearing 101 moves towards the bearing seat until the bearing 101 is installed on the bearing seat.

[0043] After the roller is placed on the roller support 2, one end of the roller abuts against the fixed base 3, and the other end is subjected to the pushing force of the pressure device 4, the pushing force of the pressure device 4 acts on the end surface of the bearing 101 through the pressing device 5, so that the bearing 101 moves towards the bearing seat under the action of the pressure, thereby achieving the installation of the bearing 102 of the roller.

[0044] Since the working surface of the pressing device 5 is annular, the annular working surface can be matched with the end surface of the bearing 101, so that the pressing device 5 can uniformly apply pressure to the entire end surface of the bearing, thereby reliably pushing the bearing 101 into the bearing seat, effectively avoiding the problem of deformation of the bearing 101 caused by uneven assembly force, and thereby ensuring the flexibility of the rotation of the roller.

[0045] In this embodiment, preferably, the surface of the fixed base 3 facing the roller is provided with an insertion hole 31, and the shaft 102 of the roller extends into the insertion hole 31.

[0046] Since the two ends of the shaft 102 protrude from the end surface of the roller, the insertion hole 31 needs to be provided when the bearing 101 is installed, so that the fixed base 3 only applies a pushing force to the end surface of the roller when the pressure device 4 is working, and the relative position of the shaft 102 and the roller is not affected.

[0047] Preferably, the shaft 102 extends into the insertion hole 31 and abuts against the bottom of the insertion hole 31, so that the shaft 102 does not move with the bearing 101 when the pressing device 5 pushes the bearing 101, and the relative position of the shaft 102 and the roller can be reliably ensured to remain unchanged.

[0048] In this embodiment, preferably, the roller support 2 is provided with an arc-shaped supporting surface which cooperates with the side surface of the roller to support the roller.

[0049] The side surface of the roller is cylindrical, and the roller support 2 is provided with an arc-shaped supporting surface to reliably support the roller. Preferably, the arc-shaped supporting surface is appropriately extended in the height direction to limit the roller in the horizontal direction, avoiding the change of the relative position of the roller when the bearing 101 is installed.

[0050] Preferably, when the bearing 101 is installed, the roller needs to be coaxial with the pressure device 5, so that the bearing 101 can better cooperate with the shaft 102. Therefore, before installation, the position of the roller support 2 can be adjusted so that the axis of the shaft 101 coincides with the axis of the pressure device 5. After adjustment, the arc-shaped supporting surface can well limit the position of the roller, so that the effect of adjustment can be effectively maintained.

[0051] In this embodiment, preferably, the roller support 2 is slidably connected with the tool body 1.

[0052] Slidably connecting the roller support 2 with the tool body 1 can realize the universality of the roller support 2 for rollers of different lengths. When the shaft 102 is longer, the roller support 2 can be slid away from the fixed base 3 to reliably support the roller.

[0053] Preferably, the roller support 2 is provided with at least two, and the one close to the fixed base 3 is arranged at an appropriate position. When supporting a roller with a longer length, usually only the roller support 2 away from the fixed base 3 needs to be moved to effectively support the roller.

[0054] Preferably, a detachable supporting bracket is arranged on the top of the roller support 2, and the supporting bracket is provided with multiple types of arc, which can cooperate with the outer surface of rollers with different diameters to realize the compatibility of rollers with different diameters.

[0055] In this embodiment, preferably, the pressure device 4 is slidably connected with the tool body 1.

[0056] For rollers of different lengths, the distance between the pressure device 4 and the fixed base 3 will also change. In order to realize the compatibility of rollers of different lengths, the position of the pressure device 4 is arranged to be slidable, and when a longer or shorter roller needs to be constructed, only the distance between the pressure device 4 and the fixed base 3 needs to be adjusted to be larger or smaller.

[0057] Preferably, the height of the pressure device 4 is constant for different diameters of the carrier roller, and the axial position of the carrier roller can be adjusted by adjusting the height of the carrier roller support 2, so as to achieve the coaxial effect of the carrier roller and the pressure device 4.

[0058] In this embodiment, preferably, the height of the arc-shaped support surface of the carrier roller support 2 is adjustable.

[0059] The carrier roller support 2 can support carrier rollers with different diameters by adjusting the height of the arc-shaped support surface. By adjusting the height of the arc-shaped support surface of the carrier roller support 2, the axial line of the supported carrier roller can still be collinear with the axial line of the pressure device 4.

[0060] In one embodiment, an adjusting bolt can be provided to adjust the height of the arc-shaped support surface of the carrier roller support 2. A sliding groove 11 is fixedly arranged on the tool body 1, an adjusting nut passes through the sliding groove 11 and cooperates with the adjusting nut, and the length of the adjusting bolt protruding from the tool body 1 can be adjusted by rotating the adjusting bolt. A sleeve that cooperates with the adjusting bolt is fixedly arranged on the carrier roller support 2, and the sleeve is sleeved on the top of the adjusting bolt. By rotating the adjusting bolt to increase or decrease the length of the adjusting bolt protruding from the tool body 1, the height of the carrier roller support 2 can be adjusted to increase or decrease.

[0061] Preferably, by arranging adjusting nuts on the upper surface and the lower surface of the tool body 1, when it is necessary to adjust the height of the carrier roller support 2 or the distance between the carrier roller support 2 and the fixed base 3, the distance between the two adjusting nuts can be adjusted to be larger, so as to easily move the position of the adjusting bolt or rotate the adjusting bolt. When it is necessary to lock the position of the carrier roller support 2, the distance between the two adjusting nuts needs to be adjusted to be smaller, so that the two adjusting nuts can exert pressure on both sides of the sliding groove 11, and the position of the adjusting bolt is locked by the pressure, thereby locking the position of the carrier roller support 2.

[0062] In another embodiment, the adjusting bolt can slide in the sliding groove 11, and a mounting hole is arranged on the carrier roller support 2. The adjusting bolt passes through the mounting hole and cooperates with the locking nut to lock the position of the carrier roller support 2. Preferably, when it is necessary to adjust the height of the carrier roller support 2, adjusting shims can be arranged between the carrier roller support 2 and the tool body 1, and the height of the carrier roller support 2 can be adjusted by adjusting the thickness of the adjusting shims.

[0063] In this embodiment, preferably, the belt conveyor carrier roller assembly tool further comprises a shim 32 arranged between the shaft 102 and the bottom surface of the insertion hole 31.

[0064] When the different sizes of the carrier roller, the length of the shaft 102 extending out of the end surface of the carrier roller is also different, in order to have better versatility, the depth of the extending hole 31 can be set to be deeper, and when the shaft 102 of different sizes is constructed, the gasket 32 of different thicknesses can be selected to cooperate with the shaft 102.

[0065] The gasket 32 of appropriate thickness is placed between the shaft 102 and the bottom surface of the extending hole 31, so that the length of the shaft 102 extending out of the end surface of the carrier roller and the thickness of the gasket 32 are equal to the depth of the extending hole 31.

[0066] In this embodiment, preferably, the gasket 32 is provided to be magnetic.

[0067] Due to the limitation of the inner diameter and the depth of the extending hole 31, the installation and removal of the gasket 32 can be difficult. The gasket 32 is provided to be a magnetic gasket 32, so that the magnetic gasket 32 can be adsorbed on the end of the shaft 102 and enter the extending hole 31 together with the shaft 102, and when the shaft 102 is taken out, the magnetic gasket 32 can also be taken out at the same time, which is beneficial to the installation and removal of the gasket 32.

[0068] Preferably, the diameter of the magnetic gasket 32 is greater than the diameter of the shaft 102, which facilitates the installation of the magnetic gasket 32, and can also avoid the magnetic gasket 32 from sliding off the end surface of the shaft 102 when the pressure device 4 is pressed against the carrier roller.

[0069] In this embodiment, preferably, the belt conveyor carrier roller assembly tool further comprises a calibration device capable of identifying the axis of the pressure device 4, and the calibration device is fixedly connected with the pressure device 4.

[0070] When the carrier roller is placed on the carrier roller support 2, whether the center line of the carrier roller is collinear with the axis of the pressure device 4 needs to be calibrated by the calibration device, and if the calibration finds that the center line of the carrier roller is not collinear with the axis of the pressure device 4, then under the assistance of the calibration of the calibration device, the height of the carrier roller support 2 can be adjusted so that the carrier roller is coaxial with the pressure device 4.

[0071] In one embodiment, a laser lamp is provided at the center position of the calibration device, the laser lamp is coaxially arranged with the calibration device, and a switch is provided on the side surface of the calibration device. When the center line position of the carrier roller needs to be calibrated, the laser lamp can be turned on, and the path of the laser lamp can represent the center line of the pressure device 4.

[0072] Specifically, after the placement of the carrier roller is completed, the laser lamp of the calibration device is turned on, the light of the laser lamp is shot to the end surface of the shaft 102 of the carrier roller and forms a photoelectric, and whether the position of the light spot is located at the center of the end surface of the shaft 102 is observed. If yes, it indicates that the carrier roller is coaxial with the pressure device 4, and if not, the height of the carrier roller support 2 needs to be adjusted according to the position of the photoelectric, until the light spot of the laser lamp is located at the center of the end surface of the shaft 102.

[0073] In another embodiment, the front end of the calibration device is provided with a pointed cone, and the tip of the pointed cone is abutted against the end face of the shaft 102 by moving the pressure device 4, and it is observed whether the tip of the pointed cone is located in the center of the end face of the shaft 102, if yes, it indicates that the shaft 102 is coaxial with the pressure device 4, if not, the height of the roller support 2 needs to be adjusted according to the actual situation until the tip of the pointed cone is located in the center of the end face of the shaft 102.

[0074] In this embodiment, preferably, the belt roller assembly tool further comprises a center finder capable of measuring the center of the shaft 102.

[0075] The center of the end face of the shaft 102 can be quickly identified by using the center finder, which facilitates the cooperation with the calibration device to determine whether the shaft 102 is coaxial with the pressure device 4.

[0076] In one embodiment, the center finder comprises a center locator 64 located at the center and a plurality of locating rods 65 fixedly connected with the center locator 64, the plurality of locating rods 65 all point to the center position of the center locator 64, and the locating rods 65 are at least four, and the plurality of locating rods 65 are located on the same straight line in pairs. The center locator is provided in a ring shape, and the hollow position in the middle of the ring-shaped center locator 64 is used to identify the axial position of the shaft 102.

[0077] In use, the center finder is attached to the end face of the shaft 102, and the distance from the edge of the shaft 102 to the center locator 64 is adjusted to be equal, so that the center locator 64 can indicate the center position of the end face of the shaft 102 at this time.

[0078] Preferably, the locating rods 65 are provided with scales to facilitate the operator to observe the distance from the edge of the shaft 102 to the center locator 64. More preferably, length values can be marked corresponding to the scales, taking the center locator 64 as the starting position 0, or setting the center of the center locator 64 as the starting position 0, and marking length values in the direction away from the center locator 64, so that the worker can more conveniently observe the distance from the intersection position of the edge of the shaft 102 and each locating rod 65 to the center locator 64, and determine whether the distance values are equal.

[0079] Preferably, the locating rods 65 are further provided with a slide 62 and a locating claw 63 cooperating with the slide 62. Optionally, two adjacent locating rods 65 are adjusted to make the working surface of the locating claw 63 to the center position of the center locator 64 equal to the radius of the shaft 102, and then the two locating claws 63 are placed above the shaft 102, so that the center finder is attached to the end face of the shaft 102, and then the center locator 64 can indicate the axial position of the shaft 102.

[0080] Preferably, only the positioning claws 63 are arranged on the optional adjacent two positioning rods 65, and the rest of the positioning rods 65 do not need to be installed with the positioning claws 63.

[0081] The center finder is matched with the calibration device, so that it can be quickly judged whether the shaft 102 is coaxial with the pressure device 4, and if it is found that the shaft 102 is not coaxial with the pressure device 4, the height of the carrier roller support 2 can be conveniently adjusted to achieve the coaxiality of the shaft 102 and the pressure device 4.
