Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, specifically a pressure-bearing transmission testing device. Background Technology

[0002] Injection molded parts are plastic parts or products manufactured through the injection molding process. Injection molding is a manufacturing technology widely used in industrial production, especially suitable for mass production of plastic products with complex shapes. Container products made from injection molded parts require pressurized gas testing to ensure their airtightness.

[0003] Chinese utility model patent CN219715079U, published on September 19, 2023, discloses a caster pressure testing device, including a base and a support frame. A rotating motor is fixedly connected inside the base, and a gear ring is driven through the power output end of the rotating motor. A turntable is fixedly connected above the gear ring, and a driving component is fixedly connected above the turntable. A conveyor belt is movably connected to one side of the driving component, and a support plate is fixedly connected above the driving component. One side of the support plate is slidably connected to the conveyor belt. A sliding groove is opened on one side of the support frame, and a fixed plate is slidably connected to one side of the sliding groove. A test wheel is fixedly connected below the fixed plate. A hydraulic rod is fixedly connected to one side of the support frame, and its lower end is fixedly connected to the fixed plate. A rotating plate is rotatably connected to one end of the support frame, and a nozzle is fixedly connected to one end of the rotating plate. A diagonal brace is fixedly connected to one side of the fixed plate, and a speed sensor is fixedly connected to one side of the test wheel. The device has the advantage of being able to test the load-bearing rotation and steering capacity of the test wheel by rotating the turntable.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing conveyor belts bear pressure by placing a pressure-bearing object under the conveyor belt, and the conveyor belt is located in the middle position. Therefore, under frequent high pressure, the conveyor belt is squeezed and deformed, resulting in damage and breakage, making it unsuitable for testing under high pressure. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that in the prior art, the conveyor belt is compressed and deformed under frequent high pressure because the conveyor belt is located in the middle and bears pressure by placing a pressure-bearing object under the conveyor belt. This results in the conveyor belt being unable to be used for high-pressure testing. The invention provides a pressure-bearing conveyor testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a pressure-bearing transmission testing device, comprising a fixed base plate; multiple support frames symmetrically fixed to the fixed base plate; multiple drive wheels and rolling wheels fixedly connected between the support frames; pressure plates located on the drive wheels and rolling wheels symmetrically fixed to the upper surface of the fixed base plate; movable plates tumblingly connected to the drive wheels and rolling wheels; multiple positioning shafts slidably inserted into the movable plates through openings; floating plates fixed to the upper ends of the positioning shafts; elastic elements sleeved on the positioning shafts; and a transmission plate fixed to the lower surface of the floating plates corresponding to the pressure plates.

[0008] Furthermore, multiple brackets are symmetrically fixed to the fixed base plate; limit covers are detachably fixed to the brackets; the limit covers are located on both sides of the movable plate.

[0009] Furthermore, multiple through-beam sensors are symmetrically fixed to the limiting cover; the through-beam sensors are located on both sides of the moving plate.

[0010] The pressure-bearing transmission testing device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model involves placing the object to be tested above a floating plate, and using a pressure device to compress the floating plate and the object to descend. The floating plate, along with the transfer plate, descends and comes into contact with the pressure plate, thus ensuring that the moving plate is not subjected to downward pressure during the up-and-down movement of the floating plate and the transfer plate, thereby protecting the drive wheel and the rolling wheel. After the test is completed, once the pressure on the object and the floating plate is released, the floating plate and the transfer plate rise due to the elastic reset of multiple elastic elements, preventing them from contacting the drive wheel and the rolling wheel and causing interference. This ensures that the pressure test does not affect the normal operation of the conveyor belt formed by the drive wheel and the rolling wheel, allowing it to withstand greater pressure and have a longer service life.

[0012] 2. This utility model uses two limiting covers to restrict the movement of the moving plate on the drive wheel and the rolling wheel before it reaches the limiting covers, thereby achieving precise positioning of the moving plate and aligning it with the pressure plate; multiple through-beam sensors are aligned with the moving plate, thereby enabling automatic detection of whether the moving plate has moved into place, thus achieving automated operation.

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0026] Please see Figure 1-8As shown, a pressure-bearing transmission testing device includes a fixed base plate 1 for fixing; multiple support frames 2 are symmetrically fixed to the fixed base plate 1; multiple drive wheels 3 and rolling wheels 4 are fixed between the support frames 2; pressure plates 5 located on the drive wheels 3 and rolling wheels 4 are symmetrically fixed to the upper surface of the fixed base plate 1; a movable plate 16 is rolledly connected to the drive wheels 3 and rolling wheels 4, forming a conveyor belt function, which can transport the movable plate 16 located above the drive wheels 3 and rolling wheels 4 to move left and right; multiple positioning shafts 7 are slidably inserted into the movable plate 16 through openings; a floating plate 9 is fixed to the upper end of the positioning shaft 7; an elastic element 8 is sleeved on the positioning shaft 7; a transfer plate 18 is fixed to the lower surface of the floating plate 9 corresponding to the pressure plate 5, and the transfer plate 18 is connected to the pressure plate 5 through the pressure plate 5. The object to be tested is placed above the floating plate 9. With the help of a pressure device, the floating plate 9 and the object are pressed down. The floating plate 9, along with the transfer plate 18, descends and comes into contact with the pressure plate 5, thus bearing the force. This ensures that the moving plate 16 is not subjected to downward pressure during the up-and-down movement of the floating plate 9 and the transfer plate 18, thereby protecting the drive wheel 3 and the rolling wheel 4. After the test is completed, the pressure on the object and the floating plate 9 disappears. Under the elastic reset of multiple elastic elements, the floating plate 9 and the transfer plate 18 rise, preventing them from contacting the drive wheel 3 and the rolling wheel 4 and causing interference. This ensures that the normal operation of the conveyor belt formed by the drive wheel 3 and the rolling wheel 4 is not affected during pressure testing, allowing it to withstand greater pressure and have a longer service life.

[0027] Multiple brackets 12 are symmetrically fixed to the fixed base plate 1; limit covers 13 are detachably fixed to the brackets 12; the limit covers 13 are located on both sides of the moving plate 16, and the moving plate 16 moving on the drive wheel 3 and the rolling wheel 4 is restricted by the two limit covers 13 before it moves to the limit covers 13, thereby achieving precise positioning of the moving plate 16 so as to align with the pressure plate 5.

[0028] Multiple through-beam sensors 14 are symmetrically fixed on the limiting cover 13. The through-beam sensors 14 are located on both sides of the moving plate 16. By aligning the multiple through-beam sensors 14 with the moving plate 16, it is possible to automatically detect whether the moving plate 16 has moved into place, thereby achieving automated operation.

[0029] A protective cover 19 is fixedly connected to the fixed base plate 1; a buffer limit block 15 is fixedly connected to the protective cover 19 corresponding to the moving plate 16. The final moving displacement of the moving plate 16 is accurately positioned by the buffer limit block 15, which facilitates the sealing pressure test.

[0030] The movable plate 16 has a relief groove 17 corresponding to the pressure plate 5. The relief groove 17 restricts the horizontal displacement of the transmission plate 18, making the vertical movement more precise.

[0031] By fixing a limiting fixture 10 to the floating plate 9, and placing the object to be tested 11 inside the limiting fixture 10, pneumatic and pressure devices can be used above the object to be tested 11, thus facilitating the selection of pneumatic and pressure devices.
