Description

Technical Field

[0001] This utility model relates to the field of encoder installation technology, specifically an encoder length measuring machine. Background Technology

[0002] With the development of modern metallurgical technology, the sizing machine, with its advantages of high rigidity, good precision, light weight, simple operation, and convenient roller changing, is widely used in bar, wire, and profile workshops. The transmission structure of this sizing machine typically includes a drive motor, gearbox, coupling, gear shaft, and rack. The power output from the drive motor is transmitted to the gear shaft via the coupling after passing through the gearbox. The gear shaft and rack mesh to drive the sizing baffle forward and backward to achieve different length requirements. After reaching the specified sizing length, two sets of lifting cylinders drive the sizing baffle to rise and fall. When the sizing baffle falls to its lowest position, the steel impacts the baffle head, achieving the corresponding sizing length, and is then sawn into sections.

[0003] Currently, to calculate the distance the length-fixing baffle moves, a large sprocket on the gear shaft drives a small sprocket via a chain. The small sprocket is then connected to the encoder's output shaft via a flexible coupling for pulse counting. The encoder outputs a fixed number of pulses per revolution (e.g., 10,000 pulses / revolution). The PLC calculates the distance the length-fixing baffle moves based on the pulse count: L = N x C / R (N: cumulative pulse count; C: sprocket circumference; R: transmission ratio). The gear shaft, as the main moving mechanism of the length-fixing machine, primarily meshes with the rack to drive the entire length-fixing baffle carriage forward and backward. In this process, the torque transmission between the large and small sprockets via the chain is crucial, directly determining the length-fixing accuracy of the machine. However, in practical applications, the chain and sprockets are prone to wear, causing chain skipping. Chain skipping directly leads to inaccurate encoder counting, resulting in substandard customization accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide an encoder length-setting machine to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an encoder length-setting machine, comprising a gear shaft for driving a length-setting baffle forward or backward, the shaft end of the gear shaft extending to the length-setting machine carriage beam, the encoder length-setting machine further comprising an encoder, a fixed bracket, and a coupling; wherein, the fixed bracket comprises a bracket body, a top plate, and a connecting member, one end of the bracket body being fixedly connected to the top plate, and the other end being fixedly connected to the length-setting machine carriage beam via the connecting member; a shaft hole is formed on the top plate, the outer shell of the encoder is fixedly connected to the top plate, and the output shaft of the encoder can pass through the shaft hole and extend into the bracket body, and is connected to the gear shaft via the coupling.

[0006] Based on the above technical features, the encoder in this utility model is directly installed to the gear shaft through a fixed bracket and coupling, which is simple in structure, easy to install and disassemble, and has a long service life. At the same time, it eliminates a series of cumbersome mechanisms such as large and small sprockets and chains, and solves the technical problem that the chain is prone to wear and tear in actual application, which causes the chain to skip teeth and the encoder to count inaccurately.

[0007] Preferably, in this technical solution, a plurality of first mounting holes are formed on the top plate, and the encoder housing can be fixed to the top plate by first bolts and nuts extending into the first mounting holes.

[0008] Based on the above technical features, the encoder is mounted on the top plate of the fixed bracket by bolts and nuts. When the encoder is accidentally damaged, it can be directly pulled out for replacement.

[0009] In this technical solution, preferably, the shaft hole is located at the center of the top plate, and a plurality of the first mounting holes are arranged circumferentially on the top plate at equal angular intervals with the shaft hole as the center.

[0010] Based on the above technical features, it can ensure that the encoder's output shaft and gear shaft are precisely aligned, reducing measurement errors caused by eccentricity or angular deviation; at the same time, the equal angular intervals of the first mounting holes can disperse stress, effectively absorb vibration and shock, and improve measurement accuracy.

[0011] Preferably, in this technical solution, the support body is a cylindrical structure, and a frustum-shaped transition section is formed at the connection between the top plate and the support body.

[0012] Based on the above technical features, the top plate and the support body are smoothly transitioned through a frustum-shaped transition section, which can evenly transfer the vibration or impact load borne by the top plate to the support body and reduce interference to the encoder.

[0013] Preferably, in this technical solution, the connector is a circular ring structure, and a plurality of second mounting holes are formed on the circumference of the connector. The fixing bracket can be fixed to the trolley beam of the length-cutting machine by means of second bolts and nuts extending into the second mounting holes. More preferably, an adjusting shim is provided between the connector and the trolley beam of the length-cutting machine, and the fixing bracket can adjust the distance between the gear shaft and the output shaft of the encoder by means of the adjusting shim. The second bolts and nuts are square hexagonal bolts and nuts.

[0014] Based on the above technical features, by adding or removing adjusting shims or changing the thickness of the adjusting shims, the distance between the gear shaft and the encoder output shaft in the coupling can be adjusted, thereby increasing the stability of the fixed length.

[0015] In this technical solution, preferably, the connector and the bracket body cooperate to form an annular recess, and the fixed bracket can be quickly positioned axially on the end face of the gear shaft through the annular recess.

[0016] Based on the above technical features, the fixed bracket can achieve rapid axial positioning by forming a fit between the annular concave platform and the shoulder of the gear shaft.

[0017] In this technical solution, preferably, a number of openings are provided on the outer circumferential sidewall of the support body.

[0018] Based on the above technical features, the opening not only effectively reduces the weight of the fixed bracket, but also facilitates the adjustment of the coupling when the encoder's output shaft is connected to the gear shaft.

[0019] In this technical solution, the bracket body, the top plate, and the connector are preferably connected as a single unit. Attached Figure Description

[0029] like Figures 1 to 4 As shown, this utility model provides a technical solution: an encoder length-setting machine, including a gear shaft 1, a length-setting machine carriage beam 2, an encoder 3, a fixed bracket 4, and a coupling 5. The shaft end of the gear shaft 1, which drives the length-setting baffle forward or backward, extends to the length-setting machine carriage beam 2. The fixed bracket 4 includes a bracket body 41, a top plate 42, and a connecting piece 43. One end of the bracket body 41 is fixedly connected to the top plate 42, and the other end is fixedly connected to the length-setting machine carriage beam 2 through the connecting piece 43. A shaft hole 421 is formed on the top plate 42. The outer shell 31 of the encoder 3 is fixedly connected to the top plate 42. The output shaft 32 of the encoder 3 can pass through the shaft hole 421 and extend into the bracket body 41, and is connected to the gear shaft 1 through the coupling 5.

[0030] In this utility model, the encoder 3 is directly installed to the gear shaft 1 through the fixed bracket 4 and the coupling 5, eliminating a series of cumbersome mechanisms such as large and small sprockets and chains. This solves the technical problem that the encoder 3 is inaccurate in counting due to chain wear and skipping teeth caused by the chain during actual application.

[0031] like Figures 1 to 3As shown, a plurality of first mounting holes 422 are formed on the top plate 42. The housing 31 of the encoder 3 can be fixed to the top plate 42 by first bolts and nuts 6 extending into the first mounting holes 422. When the encoder 3 is accidentally damaged, it can be directly pulled out for replacement. Preferably, the shaft hole 421 is located at the center of the top plate 42, and the plurality of first mounting holes 422 are arranged circumferentially on the top plate 42 at equal angular intervals with the shaft hole 421 as the center. This ensures that the output shaft 32 of the encoder 3 is accurately aligned with the gear shaft 1, reducing measurement errors caused by eccentricity or angular deviation. At the same time, the equal angular intervals of the first mounting holes 422 can disperse stress, effectively absorb vibration and shock, and improve measurement accuracy.

[0032] Specifically, such as Figure 3 As shown, the support body 41 is a cylindrical structure, and a frustum-shaped transition section 412 is formed at the connection between the top plate 42 and the support body 41. The top plate 42 and the support body 41 transition smoothly through the frustum-shaped transition section 412, which can evenly transfer the vibration or impact load borne by the top plate 42 to the support body 41, reducing interference to the encoder 3.

[0033] like Figures 1 to 3 As shown, the connector 43 is a ring structure, and several second mounting holes 431 are formed on the circumferential surface of the connector 43. The fixed bracket 4 can be fixed to the trolley beam 2 of the length-keeping machine by means of the second bolts and nuts 7 that extend into the second mounting holes 431.

[0034] like Figure 4 As shown, an adjusting shim 8 is provided between the connecting piece 43 and the trolley beam 2 of the length-cutting machine. The fixed bracket 4 can adjust the distance between the gear shaft 1 and the output shaft 32 of the encoder 3 through the adjusting shim 8. Specifically, by increasing or decreasing the adjusting shim 8 or changing the thickness of the adjusting shim 8, the distance between the gear shaft 1 and the output shaft 32 of the encoder 3 in the coupling 5 is adjusted, thereby increasing the stability of the length-cutting.

[0035] like Figure 2 As shown, this is a specific embodiment of the present invention, wherein three first mounting holes 422 are provided at equal angular intervals, and eight second mounting holes 431 are provided at equal angular intervals. Furthermore, both the first bolt and nut 6 and the second bolt and nut 7 are square hexagonal bolts and nuts to facilitate the application of force using a wrench or socket, and to facilitate inspection and maintenance.

[0036] like Figures 1 to 4 As shown, the connector 43 and the bracket body 41 cooperate to form an annular recess 9, allowing the fixed bracket 4 to be quickly positioned axially on the end face of the gear shaft 1 via the annular recess 9. Specifically... Figure 4 As shown, the fixed bracket 4 is engaged with the shoulder of the gear shaft 1 through the annular recess 9, which enables the fixed bracket 4 to be quickly positioned axially.

[0037] Furthermore, a plurality of openings 411 are provided on the outer circumferential sidewall of the bracket body 41. The openings 411 not only effectively reduce the weight of the fixed bracket 4, but also facilitate the adjustment of the coupling 5 when the output shaft 32 of the encoder 3 is connected and installed with the gear shaft 1. Preferably, two openings 411 are provided on the outer circumferential sidewall of the bracket body 41, and the two openings 411 are arranged opposite to each other.

[0038] To improve the overall strength of the fixed bracket 4, the bracket body 41, the top plate 42 and the connector 43 are connected as a single unit.
