Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor roller manufacturing, specifically to a manual welding fixture for belt conveyor roller bearing housing. 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. To maximize conveying stability and minimize wear on the belt, the bearing housings and roller bodies of the idlers must be welded together to ensure coaxiality. This prevents eccentricity during idler rotation, reduces vibration and noise, and also minimizes friction between the idlers and the belt.
[0004] Currently, in the small-batch production of idler rollers, the lack of dedicated tooling for positioning makes it difficult to guarantee the relative position of the bearing housing and the roller body during small-batch trial production. Furthermore, because the welding surface between the roller body and the bearing housing is circular, to ensure the relative position remains constant during welding, the operator typically rotates the idler roller around once to weld the roller body and bearing housing. Therefore, the quality and efficiency of idler roller production are both very low during small-batch trial production. Utility Model Content
[0005] The purpose of this utility model is to provide a manual welding fixture for belt conveyor idler bearing housings. This fixture can ensure that the idler body and the bearing housing are in a coaxial relative position, and welding is very convenient when using this fixture.
[0006] To achieve the above objectives, this utility model provides a manual welding fixture for belt conveyor idler bearing housings. The manual welding fixture for belt conveyor idler bearing housings includes a rotating worktable, a fixture base disposed on the rotating worktable, a positioning block, and a positioning rod fixedly connected to the fixture base. The positioning rod is perpendicular to the working surface of the fixture base, and the axis of the positioning rod coincides with the rotation center of the rotating worktable.
[0007] The positioning block is configured as a cylinder that mates with the bearing seat of the idler roller, and the axis of the positioning block is coaxial with the positioning rod.
[0008] Preferably, the manual welding fixture for the belt conveyor roller bearing housing further includes a fastening nut, which cooperates with the positioning rod to fix the bearing housing.
[0009] Preferably, the tooling base is detachably connected to the rotary worktable.
[0010] Preferably, the rotary worktable is provided with a positioning shaft, and the axis of the positioning shaft coincides with the rotation center of the rotary worktable.
[0011] Preferably, the rotary worktable is further provided with a limit rod, and the tooling base is provided with a positioning hole that cooperates with the limit rod.
[0012] Preferably, the rotary table further includes a control switch, which controls the rotary table to start or stop.
[0013] Preferably, a boss is fixedly provided on the outer edge of the rotary worktable, the height of the boss is higher than the height of the rotary worktable, and the boss does not rotate with the rotary worktable.
[0014] According to the above technical solution, when using the manual welding fixture for the belt conveyor idler roller bearing housing of this utility model, the positioning block needs to be fitted onto the positioning rod first, and then the bearing housing and the idler roller body 1 are assembled. After the bearing housings at both ends are engaged with the idler roller body, one end of the idler roller body is fitted downward onto the positioning rod. By pressing the idler roller body downward, the bearing housing and the positioning block are engaged, that is, the positioning block is embedded in the bearing housing. By setting the positioning block and the positioning rod to be coaxial, it can be ensured that the bearing housing at the lower end of the idler roller body is coaxial with the positioning rod.
[0015] Then, a positioning block is placed inside the bearing housing at the upper end of the idler roller body. This positioning block is still required to be coaxial with the positioning rod, thereby ensuring that the bearing housings at both ends of the idler roller body are coaxial with the positioning rod, that is, achieving the coaxial setting between the bearing housing and the positioning rod.
[0016] The positioning rod is set perpendicular to the working surface of the tooling base, so that after the idler roller body is placed on the working surface of the tooling base, the positioning rod can be perpendicular to the cross-section of the idler roller body, thereby ensuring that the axis of the idler roller body is parallel to the axis of the positioning rod.
[0017] The positioning block is cylindrical, so the cooperation between the positioning block and the bearing seat can ensure that the roller body and the positioning rod are coaxial.
[0018] Therefore, using the manual welding fixture for the conveyor belt idler roller bearing housing can ensure the coaxiality of the idler roller body and the bearing housing.
[0019] After the bearing seats at both ends of the idler roller body are installed, the rotary table is started. The idler roller located on the tooling base will then rotate with the rotary table. Since the axis of the positioning rod coincides with the rotation center of the rotary table, the actual position of the idler roller remains unchanged during rotation. By adjusting the rotation speed of the rotary table, the idler roller can rotate at a suitable speed. The operator only needs to stand in place to weld the idler roller body to the bearing seat. Therefore, setting up a rotary table can greatly improve the welding efficiency of the idler roller.
[0020] Once one end of the idler roller is welded, flipping the idler roller body allows for welding to the other end of the idler roller body.
[0021] Preferably, the rotation speed of the rotary table is set to be adjustable to meet the operator's requirements for different welding speeds.
[0022] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0031] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0032] In this utility model, unless otherwise stated, directional words such as "vertical," "coincident," "coaxial," "outer edge," and "higher than" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.
[0033] See Figure 1 A manual welding fixture for belt conveyor idler bearing housing includes a rotary worktable 1, a fixture base 2 set on the rotary worktable 1, a positioning block 4, and a positioning rod 3 fixedly connected to the fixture base 2. The positioning rod 3 is perpendicular to the working surface of the fixture base 2, and the axis of the positioning rod 3 coincides with the rotation center of the rotary worktable 1.
[0034] The positioning block 4 is a cylinder that mates with the bearing seat 101 of the idler roller, and the positioning block 4 is coaxial with the positioning rod 3.
[0035] By implementing the above technical solution, when using the manual welding fixture for the bearing housing of the conveyor belt idler, the positioning block 4 needs to be fitted onto the positioning rod 3 first. Then, the bearing housing 101 and the idler body 102 are assembled. After the bearing housings 101 at both ends are engaged with the idler body 102, one end of the idler body 102 is fitted downward onto the positioning rod 3. By pressing the idler body 102 downward, the bearing housing 101 and the positioning block 4 are engaged. That is, the positioning block 4 is embedded in the bearing housing 101. By setting the positioning block 4 and the positioning rod 3 to be coaxial, it can be ensured that the bearing housing 101 at the lower end of the idler body 102 is coaxial with the positioning rod 3.
[0036] Then, a positioning block 4 is placed inside the bearing seat 101 at the upper end of the idler body 102. The positioning block 4 is still required to be coaxial with the positioning rod 3, thereby ensuring that the bearing seats 101 at both ends of the idler body 102 are coaxially set with the positioning rod 3, that is, the coaxial setting between the bearing seat 101 and the positioning rod 3 is achieved.
[0037] The positioning rod 3 is set perpendicular to the working surface of the tooling base 2, so that after the roller body 102 is placed on the working surface of the tooling base 2, the positioning rod 3 can be perpendicular to the cross section of the roller body 102, thereby ensuring that the axis of the roller body 102 is parallel to the axis of the positioning rod 3.
[0038] The positioning block 4 is cylindrical, so the cooperation between the positioning block 4 and the bearing seat 101 can ensure that the roller body 102 and the positioning rod 3 are coaxial.
[0039] Therefore, using the manual welding fixture for the conveyor belt idler roller bearing housing can ensure the coaxiality of the idler roller body 102 and the bearing housing 101.
[0040] After the bearing seats 101 at both ends of the idler roller body 102 are installed, the rotary table 1 is started. The idler roller located on the tooling base 2 will then rotate with the rotary table 1. Since the axis of the positioning rod 3 coincides with the rotation center of the rotary table 1, the actual position of the idler roller remains unchanged during rotation. By adjusting the rotation speed of the rotary table 1, the idler roller can rotate at a suitable speed. The operator only needs to stand in place to weld the idler roller body 102 and the bearing seat 101. Therefore, by setting up the rotary table 1, the welding efficiency of the idler roller can be greatly improved.
[0041] Once one end of the idler roller is welded, flipping the idler roller body 102 allows for welding of the other end of the idler roller body 102.
[0042] Preferably, the rotation speed of the rotary table 1 is set to be adjustable to meet the operator's requirements for different welding speeds.
[0043] In this embodiment, preferably, the manual welding fixture for the belt conveyor roller bearing housing also includes a fastening nut 5, which cooperates with the positioning rod 3 to fix the bearing housing 101.
[0044] To ensure that the relative positional relationship between the idler body 102 and the bearing seat 101 does not change during the welding process, and thus ensure that the coaxiality between the idler body 102 and the bearing seat 101 still meets the requirements after welding, a fastening nut 5 that cooperates with it can be provided on the positioning rod 3. After the relative position between the idler and the positioning rod 3 is fixed, the positioning block 4 applies a certain pressure to the bearing seat 101 by tightening the fastening nut 5. Under the action of this pressure, the bearing seat 101 and the idler body 102 can be relatively fixed.
[0045] During the welding process, the stable bearing seat 101 can also provide a certain support force for the welding torch, thereby further ensuring the stability of the relative position between the bearing seat 101 and the roller body 102 during the welding process.
[0046] In this embodiment, preferably, the tooling base 2 is detachably connected to the rotary table 1.
[0047] Since the length and diameter of the positioning rod 3 need to be compatible with the shaft of the idler roller, different idler rollers require different positioning rods 3 during production. In actual use, the adaptability of the rotary table 1 to trial production of different idler rollers can be achieved by changing the tooling base 2, thus making the rotary table more versatile.
[0048] In this embodiment, preferably, a positioning shaft is provided on the rotary table 1, and the axis of the positioning shaft coincides with the rotation center of the rotary table 1.
[0049] The axis of the positioning shaft is set to coincide with the rotation center of the rotary table 1. At the same time, a mounting hole that mates with the positioning shaft is provided on the side of the tooling base 2 that mates with the rotary table 1. This allows the tooling base 2 to be reliably restricted in position by mateturing the mounting hole with the positioning shaft when it is replaced, so that the axis of the positioning rod 3 can always coincide with the rotation center line of the rotary table 1.
[0050] In this embodiment, preferably, the rotary table 1 is also provided with a limit rod, and the tooling base 2 is provided with a positioning hole that cooperates with the limit rod shown.
[0051] The tooling base 2, through the cooperation of the positioning hole and the limiting rod, allows the tooling base 2 to rotate together with the rotary worktable 1 during its rotation.
[0052] Preferably, at least two limiting rods are provided. The two limiting rods can fix the relative position of the tooling base 2 and the rotary table 1, so as to avoid the positioning shaft being subjected to the reaction force of the tooling base 2 at the moment when the rotary table 1 starts or stops, thereby avoiding the deformation of the positioning shaft during use and ensuring the reliability of the relative positioning between the tooling base 2 and the rotary table 1.
[0053] In this embodiment, preferably, the rotary table 1 further includes a control switch, which controls the rotary table 1 to stop rotating.
[0054] When welding is required on the idler roller, the rotating worktable 1 can be started to rotate the idler roller. At this time, the welding gun is placed in the gap between the idler roller body 102 and the bearing seat 101, and welding on the idler roller can begin.
[0055] During the welding process, if it is necessary to stop the rotating worktable 1 in order to adjust the rollers located on the rotating worktable 1, the rotating worktable 1 can be stopped by controlling the switch. After the adjustment is completed, the rotating worktable 1 can be started again by controlling the switch.
[0056] In one embodiment, the control switch is configured as a push-button switch, which controls the drive mechanism of the rotary table 1 to start or stop. When the push-button switch is pressed, the drive mechanism switches between starting and stopping.
[0057] Preferably, the operator can control the button with their foot, and start or stop the rotary worktable 1 by stepping on the button, so that the rotary worktable 1 can be controlled without using both hands during the production process.
[0058] In this embodiment, preferably, a boss 6 is fixedly provided on the outer edge of the rotary worktable 1, the height of the boss 6 is higher than the height of the rotary worktable 1, and the boss 6 does not rotate with the worktable.
[0059] In another embodiment, the operator can also stop the rotary worktable 1 urgently by stepping on it. During welding, the operator's foot rests on the boss 6 but does not contact the rotary worktable 1. If an emergency stop is needed, the operator can lower their toes. The toes on the rotary worktable 1 apply pressure, which is detected by a sensor, which outputs a control signal to stop the rotary worktable 1 from rotating. When the rotary worktable 1 needs to continue rotating, the operator lifts their toes, releasing the pressure on the rotary worktable 1, eliminating the sensor's control signal, and allowing the rotary worktable 1 to resume rotating.
[0060] The protrusion 6 provides a preparatory position for the operator to control the rotating worktable 1. The operator can control the start or stop of the rotating worktable 1 simply by stepping on the protrusion 6 and raising or lowering their toes.
[0061] Preferably, an annular pressure sensor is installed near the center of the lower surface of the rotary table 1. This annular pressure sensor is positioned between the drive mechanism and the rotary table 1. During normal use, there is no relative movement between the annular pressure sensor and the rotary table 1; they both rotate together with the drive mechanism. When a worker presses down on the rotary table 1 with their foot, the rotary table 1 exerts pressure on the annular pressure sensor. Upon detecting this pressure, the annular pressure sensor outputs a control signal, which stops the drive mechanism from rotating. When the worker releases the rotary table 1, the pressure on the annular pressure sensor disappears, the annular pressure sensor stops outputting control signals, the drive mechanism restarts, and the rotary table 1 continues to rotate.
[0062] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
[0064] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
