Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller chain production technology, and in particular to a heating and turning frame for heat treatment of roller chain accessories. Background Technology
[0002] A roller chain is a type of chain used to transmit mechanical power. It is widely used in household, industrial, and agricultural machinery, such as conveyors, plotters, printing presses, automobiles, motorcycles, and bicycles. It consists of a series of short cylindrical rollers linked together and driven by a gear called a sprocket. It is a simple, reliable, and efficient power transmission device.
[0003] Roller chain plates require heat treatment. During heat treatment, workers usually lay the chain plates evenly and put them into a heating furnace for heating, and then cool them with oil. However, in some cases, due to the thickness of the laid chain plates, uneven heating and incomplete heating may occur, and some areas may not meet the heat treatment requirements. Therefore, a heating and turning frame is needed to limit the thickness of the laid chain plates and control the turning of the clamped chain plates during the heating process to ensure thorough and uniform heating. Utility Model Content
[0004] This utility model addresses the deficiencies in the prior art by providing a heating and turning frame for heat treatment of roller chain accessories.
[0005] This utility model is achieved through the following technical solution:
[0006] A heating and turning frame for heat treatment of roller chain accessories includes a heating furnace frame, a conveyor belt, a limiting plate, a toothed plate, and a turning and heating device. The conveyor belt is installed at both ends of the top of the heating furnace frame. The limiting plate is fixed to the surface of the conveyor belt. The toothed plate is fixedly set on the upper surface of the heating furnace frame. The turning and heating device is clamped on the top of the limiting plate. The turning and heating device includes a positioning seat, a connecting seat, a positioning rotating tube, a placement frame, a locking shaft, a gear, and a mesh cover. The positioning seat is clamped on the top of the limiting plate. The connecting seat is fixed to both ends of the top of the positioning seat. The positioning rotating tube is movably connected to the connecting seat. The locking shaft is fixedly set at both ends of the placement frame. The gear is fixed to the surface of the locking shaft. The mesh cover is installed on the top of the placement frame.
[0007] In a preferred embodiment of this utility model, the positioning card seat is a hollow structure, and a card groove that cooperates with the limiting card plate is fixedly provided at the bottom of the positioning card seat;
[0008] The positioning bracket is mainly used to install the placement frame for the chain plate and to lock it at the top limit plate of the conveyor belt, so that it can move into the furnace under the action of the conveyor belt.
[0009] In a preferred embodiment of the present invention, the outer side of the positioning rotary tube is provided with threads, the connecting seat is provided with a threaded hole that mates with it, and a limit ring is fixedly provided at one end of the positioning rotary tube and its surface.
[0010] In a preferred embodiment of this utility model, the inner side of the positioning rotating tube has an insertion hole that mates with the retaining shaft;
[0011] Rotate the positioning tube to move it forward, and set the inner insertion hole outside the card shaft to achieve the effect of positioning and connecting the placed grid frame.
[0012] In a preferred embodiment of this utility model, the mesh cover is fixedly connected to the top of the mesh frame, which effectively prevents the mesh cover from falling off or cracking, thus preventing the internal chain plate from falling off during rotation.
[0013] In a preferred embodiment of this utility model, the gear engages with the toothed plate, and when the gear moves to the top of the toothed plate, the gear meshes with the toothed plate.
[0014] The beneficial effects of this utility model are:
[0015] The heating and turning frame for heat treatment of roller chain accessories effectively limits the thickness of the chain plates, effectively limits the placement frame for the chain plates, and controls the rotation of the placement frame during its transfer in the heating furnace by meshing the gears on the shaft surface with the toothed plates on the heating furnace frame surface, thereby ensuring uniform heating of the internal chain plates and guaranteeing the heat treatment effect of the chain plates.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.
[0022] like Figure 1-4 The heating and turning frame for heat treatment of roller chain accessories shown includes a heating furnace frame 1, a conveyor belt 2, a limiting plate 3, a toothed plate 4, and a turning heating device 5. The conveyor belt 2 is installed at both ends of the top of the heating furnace frame 1. The limiting plate 3 is fixed to the surface of the conveyor belt 2. The toothed plate 4 is fixedly set on the upper surface of the heating furnace frame 1. The turning heating device 5 is clamped on the top of the limiting plate 3. The turning heating device 5 includes a positioning seat 51, a connecting seat 52, a positioning rotating tube 53, a placing frame 54, a clamping shaft 55, a gear 56, and a mesh cover 57. The positioning seat 51 is clamped on the top of the limiting plate 3. The connecting seat 52 is fixed to both ends of the top of the positioning seat 51. The positioning rotating tube 53 is movably connected to the connecting seat 52. The clamping shaft 55 is fixedly set at both ends of the placing frame 54. The gear 56 is fixed to the surface of the clamping shaft 55. The mesh cover 57 is installed on the top of the placing frame 54.
[0023] Specifically, the positioning card holder 51 has a hollow structure. The bottom of the positioning card holder 51 is fixedly provided with a card groove that cooperates with the limiting card plate 3. The outer side of the positioning rotating tube 53 is provided with threads. The connecting seat 52 is provided with a threaded hole that cooperates with it. One end of the positioning rotating tube 53 and its surface are fixedly provided with a limiting ring. The inner side of the positioning rotating tube 53 is provided with an insertion hole that cooperates with the card shaft 55. The mesh cover 57 is fixedly connected to the top of the placing mesh frame 54. The gear 56 cooperates with the toothed plate 4. When the gear 56 moves to the top of the toothed plate 4, the gear 56 meshes with the toothed plate 4.
[0024] In this embodiment, the chain plate is first laid inside the placement frame 54, and then the mesh cover 57 is installed on the top of the placement frame 54. The mesh cover 57 can be fixed to the placement frame 54 by means of screws or wire binding, mainly to prevent the chain plate placed inside from falling off during rotation. Then, the end of the placement frame 54 with the chain plate is inserted into the inner hole of the positioning rotating tube 53. Rotating the positioning rotating tube 53 can make it move inward, thereby limiting the outer side of one end of the clamping shaft 55, so that the placement frame 54 can rotate inside the positioning rotating tube 53 according to the clamping shaft 55. After installation, the positioning card seat 51 is inserted into the top of the conveyor belt 2, and the bottom slot of the positioning card seat 51 is inserted into the top of the limiting card plate 3.
[0025] Furthermore, as the conveyor belt 2 operates, under the action of the limiting plate 3, the positioning plate 51 moves into the heating furnace. When the gear 56 moves to the top of the toothed plate 4, the gear 56 meshes with the toothed plate 4, thereby causing the mesh frame 54 to rotate slowly in the heating furnace, thus achieving uniform and thorough heating and ensuring that the heating temperature of all areas of the chain plate reaches the heat treatment requirements.
