Description

Technical Field

[0001] This utility model relates to the field of resin grinding wheel technology, and in particular to a temperature-controlled curing fixture for improving the rigidity of resin grinding wheels. Background Technology

[0002] Resin-based rail grinding wheels are specialized grinding wheels made of resin. They are mainly used for grinding rails. They are made by mixing and pressing abrasives (such as corundum and silicon carbide), resin binders (such as phenolic resin) and fillers. The resin needs to be cross-linked and hardened by heating and curing in a fixture to form a stable three-dimensional network structure.

[0003] However, in existing equipment, resin grinding wheel is usually heated directly when clamping, which can easily lead to uneven heating of the resin grinding wheel and affect its rigidity. Therefore, a temperature-controlled curing fixture is proposed to improve the rigidity of resin grinding wheel. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a temperature-controlled curing fixture for improving the rigidity of resin grinding wheel rails.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a temperature-controlled curing fixture for improving the rigidity of resin grinding steel rail grinding wheels, comprising a worktable, a gantry frame fixedly connected to the upper surface of the worktable, a PLC control module fixedly installed on one side of the gantry frame, a hydraulic cylinder fixedly connected to the bottom of the gantry frame, heating boxes fixedly connected to the piston end of the hydraulic cylinder and the upper surface of the worktable, the bottom of the lower heating box communicating with the bottom of the worktable, a baffle frame fixedly connected to the bottom of the worktable, a baffle assembly provided on the baffle frame, and a quick-release assembly provided on the opposite side of each heating box;

[0006] The turbulence-disrupting component includes a rotating shaft rotatably connected to the bottom of the turbulence-disrupting frame. Multiple fan blades are fixedly connected to the rotating shaft. The rotating shaft drives the multiple fan blades to rotate, thereby disturbing the airflow inside the two heating boxes and making the temperature inside the two heating boxes evenly distributed.

[0007] As a further description of the above technical solution:

[0008] A rotating motor is fixedly connected to the bottom of the spoiler frame. The output shaft of the rotating motor is fixedly connected to one end of the rotating shaft. The rotating motor is electrically connected to the PLC control module. The PLC control module controls the rotating motor to drive the rotating shaft to rotate.

[0009] As a further description of the above technical solution:

[0010] The lower heating box has multiple heating tubes fixedly installed inside, and a rigid sealing gasket is fixedly connected to its upper surface. Each heating tube is electrically connected to a PLC control module. The upper heating box has a temperature sensor fixedly installed on its inner top. The temperature sensor is electrically connected to the PLC control module. The PLC control module controls the multiple heating tubes to heat. The temperature sensor transmits the temperature signals from the two heating boxes to the PLC control module, which then controls the multiple heating tubes to maintain a constant temperature.

[0011] As a further description of the above technical solution:

[0012] Each heating box has four sliding grooves on one side. A cross-shaped fixing frame is slidably connected in the four sliding grooves at the same level. Each cross-shaped fixing frame has a snap-fit ​​hole on the opposite side. An upper clamp is fixedly connected to the bottom of the upper cross-shaped fixing frame, and a lower clamp is fixedly connected to the upper surface of the lower cross-shaped fixing frame. The resin grinding steel rail grinding wheel blank is placed into the lower clamp, and then the piston end of the hydraulic cylinder drives the upper heating box to move downward, so that the two heating boxes close. At the same time, the resin grinding steel rail grinding wheel blank is clamped in the middle by the upper and lower clamps.

[0013] As a further description of the above technical solution:

[0014] The quick-release assembly includes a fixed frame fixedly connected to one side of the heating box. A sliding rod is slidably connected through one side of the fixed frame. A handle is rotatably connected to one end of the sliding rod. One side of the handle is engaged with the outer side of the fixed frame. Moving the handle causes the handle to move the sliding rod.

[0015] As a further description of the above technical solution:

[0016] The other end of the sliding rod is fixedly connected to a snap-fit ​​post. The snap-fit ​​post is slidably connected to one side of the corresponding heating box and is adapted to the corresponding snap-fit ​​hole. The sliding rod drives the snap-fit ​​post to move, so that the snap-fit ​​post disengages from the snap-fit ​​hole and compresses the return spring. Then the cross fixing bracket is taken out, which makes it convenient for the staff to replace the matching upper and lower clamps according to the model of the resin grinding wheel.

[0017] As a further description of the above technical solution:

[0018] A return spring is fitted on the sliding rod. One end of the return spring is fixedly connected to the inside side of the fixed frame, and the other end is fixedly connected to one side of the snap-fit ​​post. Through the elastic reset of the return spring, the snap-fit ​​post is pushed into the corresponding snap-fit ​​hole to quickly fix the cross-shaped fixing frame.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with the existing technology, the temperature-controlled curing fixture for improving the rigidity of resin grinding steel rail grinding wheels is equipped with a rotating motor, a rotating shaft, and fan blades. The rotating motor drives the rotating shaft to rotate, and the rotating shaft drives multiple fan blades to rotate. The multiple fan blades disturb the airflow inside the two heating chambers, so that the temperature inside the two heating chambers is evenly distributed. This ensures that the resin grinding steel rail grinding wheel blanks inside the upper and lower fixtures are heated evenly, thereby improving the rigidity of the resin grinding steel rail grinding wheels.

[0021] 2. Compared with existing technologies, this temperature-controlled curing fixture for improving the rigidity of resin grinding steel rail grinding wheels uses a fixed frame, sliding rod, locking pin, handle, and return spring. By moving the handle, the handle moves the sliding rod, which in turn moves the locking pin, causing the locking pin to disengage from the locking hole and compressing the return spring. Then, the cross-shaped fixing frame can be removed, making it convenient for workers to replace the upper and lower fixtures with matching ones according to the model of the resin grinding steel rail grinding wheels being produced.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 8This utility model provides a temperature-controlled curing fixture for improving the rigidity of resin grinding steel rail grinding wheels: It includes a worktable 1, a gantry frame 2 fixedly connected to the upper surface of the worktable 1, a PLC control module 8 fixedly installed on one side of the gantry frame 2, a hydraulic cylinder 3 fixedly connected to the bottom of the gantry frame 2, and heating boxes 4 fixedly connected to the piston end of the hydraulic cylinder 3 and the upper surface of the worktable 1. The bottom of the lower heating box 4 is connected to the bottom of the worktable 1. Multiple heating tubes 11 are fixedly installed inside the lower heating box 4, and a rigid sealing gasket 14 is fixedly connected to its upper surface. The rigid sealing gasket 14 improves the sealing performance at the connection between the two heating boxes 4. Each heating tube 11 is electrically connected to the PLC control module 8. A temperature sensor 12 is fixedly installed on the top inner surface of the upper heating box 4 and is electrically connected to the PLC control module 8. The PLC control module 8 controls the multiple heating tubes 11 to perform heating. Temperature sensor 12 transmits the temperature signal inside the two heating boxes 4 to PLC control module 8. PLC control module 8 controls multiple heating tubes 11 to keep the temperature constant. Each heating box 4 has four sliding grooves on one side. A cross fixing frame 5 is slidably connected in the four sliding grooves at the same level. Each cross fixing frame 5 has a snap-fit ​​hole on the side away from each other. The bottom of the upper cross fixing frame 5 is fixedly connected to the upper clamp 6, and the upper surface of the lower cross fixing frame 5 is fixedly connected to the lower clamp 7. The resin grinding steel rail grinding wheel blank is placed into the lower clamp 7. Then the piston end of the hydraulic cylinder 3 drives the upper heating box 4 to move downward, so that the two heating boxes 4 are closed. At the same time, the resin grinding steel rail grinding wheel blank is clamped in the middle by the upper clamp 6 and the lower clamp 7. The bottom of the worktable 1 is fixedly connected to the baffle frame 9. The baffle frame 9 is equipped with a baffle assembly 10. Each heating box 4 has a quick release assembly 13 on the side away from each other.

[0034] To achieve uniform temperature distribution, the turbulence assembly 10 includes a rotating shaft 102 rotatably connected to the bottom of the turbulence frame 9. Multiple fan blades 103 are fixedly connected to the rotating shaft 102. A rotating motor 101 is fixedly connected to the bottom of the turbulence frame 9. The output shaft of the rotating motor 101 is fixedly connected to one end of the rotating shaft 102. The rotating motor 101 is electrically connected to the PLC control module 8. The rotating motor 101 drives the rotating shaft 102 to rotate, and the rotating shaft 102 drives the multiple fan blades 103 to rotate. The multiple fan blades 103 turbulent the airflow inside the two heating boxes 4, so that the temperature inside the two heating boxes 4 is evenly distributed, ensuring that the resin grinding steel rail grinding wheel blanks inside the upper clamp 6 and lower clamp 7 are evenly heated, and improving the rigidity of the resin grinding steel rail grinding wheel.

[0035] To achieve quick assembly and disassembly, the quick-release assembly 13 includes a fixed frame 131 fixedly connected to one side of the heating box 4. A sliding rod 132 is slidably connected through one side of the fixed frame 131. A handle 134 is rotatably connected to one end of the sliding rod 132. One side of the handle 134 is engaged with the outer side of the fixed frame 131. A locking post 133 is fixedly connected to the other end of the sliding rod 132. A return spring 135 is sleeved on the sliding rod 132. One end of the return spring 135 is fixedly engaged with the inner side of the fixed frame 131. One end is fixedly connected to the other end, and the other end is fixedly connected to one side of the snap-fit ​​post 133. The snap-fit ​​post 133 is slidably connected to one side of the corresponding heating box 4 and is adapted to the corresponding snap-fit ​​hole. Move the handle 134, and the handle 134 drives the sliding rod 132 to move. The sliding rod 132 drives the snap-fit ​​post 133 to move, so that the snap-fit ​​post 133 is disengaged from the snap-fit ​​hole and the return spring 135 is compressed. Then, the cross fixing bracket 5 is taken out, so that the staff can replace the matching upper clamp 6 and lower clamp 7 according to the model of the resin grinding steel rail grinding wheel.

[0036] Working principle: The resin-bonded steel rail grinding wheel blank is placed into the lower clamp 7. Then, the piston end of the hydraulic cylinder 3 drives the upper heating box 4 to move downward, closing the two heating boxes 4. Simultaneously, the resin-bonded steel rail grinding wheel blank is clamped in the middle by the upper clamp 6 and the lower clamp 7. Then, the PLC control module 8 controls multiple heating tubes 11 to heat the wheel. The temperature sensor 12 transmits the temperature signal inside the two heating boxes 4 to the PLC control module 8. The PLC control module 8 controls the multiple heating tubes 11 to maintain a constant temperature. At the same time, the PLC control module 8 controls the rotary motor 101, which drives the rotating shaft 102 to rotate. Shaft 102 drives multiple fan blades 103 to rotate, which disturbs the airflow inside the two heating boxes 4, making the temperature inside the two heating boxes 4 evenly distributed. This ensures that the resin grinding steel rail grinding wheel blanks inside the upper clamp 6 and lower clamp 7 are heated evenly, improving the rigidity of the resin grinding steel rail grinding wheel. The handle 134 is turned, which drives the sliding rod 132 to move. The sliding rod 132 drives the locking post 133 to move, causing the locking post 133 to disengage from the locking hole and compress the return spring 135. Then, the cross fixing bracket 5 is taken out, which makes it convenient for the staff to replace the upper clamp 6 and lower clamp 7 with matching ones according to the model of the resin grinding steel rail grinding wheel being produced.
