[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] The utility model provides an absolute value encoder, which is provided with a shell outside a heating furnace, a slide groove is provided on the side wall of the shell, and a limit assembly is provided on the side wall of the heating furnace, including a limit shell, a limit slide groove, a slide plate, a spring and a limit plate. The slide plate is pulled downward to squeeze the spring and drive the limit plate to be retracted into the limit slide groove, the absolute value encoder is placed in the slide groove, the slide plate is released, and the spring rebounds to push the slide plate and the limit plate to slide toward the shell, the limit plate blocks the slide groove opening, the absolute value encoder is limited and fixed in the slide groove, and the installation, disassembly and maintenance of the absolute value encoder are convenient.

[0029] Figure 1-5 The following is a schematic diagram of the structure of an absolute encoder implementation scheme of the utility model. Figure 1-Figure 5 An absolute value encoder in this embodiment includes a heating furnace 100 , a shell 200 , an absolute value encoder 300 and a limit assembly 400 .

[0030] A door panel 110 is hingedly connected to the side wall of the heating furnace 100 .

[0031] The housing 200 is mounted on the side wall of the heating furnace 100. The side wall of the housing 200 is provided with a slide groove 210. A spring 230 is mounted on the inner wall of the slide groove 210. A push plate 240 is mounted on the other end of the spring 230. When the absolute encoder 300 slides into the slide groove 210, the guide plate 310 is embedded in the guide groove 220 and slides in the guide groove 220 as the absolute encoder 300 slides, thereby guiding the absolute encoder 300 and controlling the left and right sides of the absolute encoder 300. The absolute value encoder 300 is limited in the up and down directions. When the side wall of the absolute value encoder 300 abuts against the side wall of the push plate 240, as the absolute value encoder 300 slides, the absolute value encoder 300 pushes the push plate 240 to squeeze the spring 230 until the absolute value encoder 300 is completely received into the slide groove 210. When the absolute value encoder 300 needs to be removed, the spring 230 rebounds and pushes the push plate 240 to pop the absolute value encoder 300 out of the opening of the slide groove 210, making it convenient to take the absolute value encoder 300.

[0032] The absolute encoder 300 is located inside the slide 210, and the symmetrical side walls of the slide 210 are provided with guide grooves 220. The symmetrical side walls of the absolute encoder 300 are provided with guide plates 310, and the guide plates 310 are located inside the guide grooves 220. The signal line of the absolute encoder 300 is directly connected to the input point of the PLC without passing through the cam controller, such as Figure 4 and Figure 5 As shown, the output signal of the absolute encoder 300 is usually in Gray code format. According to the point information obtained by the PLC, the binary signal group is decoded into Gray code to obtain the value V corresponding to the resolution of the absolute encoder 300. The user inputs the required control point into the PLC, and the PLC performs real-time comparison based on the user-set point and the encoder value V, and calculates the mechanical transmission control point inside the PLC. Compared with the traditional absolute encoder, the absolute encoder 300 in the present application can effectively prevent the damage of the cam setter from causing damage to the mechanical structure, and break through the control point limit.

[0033] The limiting assembly 400 includes a limiting shell 410 installed on the side wall of the heating furnace 100, a limiting slide groove 420 opened on the side wall of the limiting shell 410, a slide plate 430 located inside the limiting slide groove 420, a second spring 440 installed at the bottom of the slide plate 430, and a limiting plate 450 installed on the top of the slide plate 430. The symmetrical side walls of the limiting slide groove 420 are provided with second guide grooves 421, and the symmetrical side walls of the slide plate 430 are provided with second guide plates 431, and the second guide plates 431 are located inside the second guide grooves 421. The side wall of the limiting plate 450 is provided with a pull plate 451, and the outer wall of the pull plate 451 is wrapped with a rubber layer. By pulling the slide plate 4 30 makes the slide plate 430 slide inside the limiting slide groove 420 and squeeze the second spring 440, the second guide plate 431 slides inside the second guide groove 421, the sliding of the slide plate 430 drives the limiting plate 450 to be retracted into the limiting slide groove 420, at this time, the absolute value encoder 300 is pushed to make the absolute value encoder 300 completely retracted into the slide groove 210, release the slide plate 430, the second spring 440 rebounds and pushes the slide plate 430 and the limiting plate 450 to move upward, the limiting plate 450 moves to the opening of the slide groove 210, covers the opening of the slide groove 210, when the absolute value encoder 300 is limited and fixed inside the slide groove 210.

[0034] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
