Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a straightening device for massage chair shaft parts. Background Technology

[0002] In the manufacturing process of massage chairs, shaft components are crucial parts, and their straightness directly affects the stability of the massage chair's operation and the massage effect. However, during the processing, transportation, or use of shaft components, bending and deformation can easily occur due to various factors.

[0003] Traditional methods for straightening shaft parts mostly involve manual straightening or simple mechanical straightening equipment. Manual straightening is inefficient, labor-intensive, and difficult to guarantee straightening accuracy. Simple mechanical straightening equipment has poor applicability and cannot meet the straightening needs of massage chair shaft parts of different specifications and curvatures. At the same time, it cannot precisely control the straightening process, resulting in unsatisfactory straightening effects and affecting the overall quality and performance of the massage chair. Therefore, a straightening device for massage chair shaft parts is proposed to address the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A straightening device for shaft parts of a massage chair includes a worktable mounted above a base, multiple identical position adjustment mechanisms installed inside the front and rear ends of the base, side pressing mechanisms mounted on the left and right sides of the worktable, and a pressing mechanism mounted above the worktable. A top plate is mounted on the top of the worktable, and a control module is located on the rear side of the worktable. The pressing mechanism includes a first hydraulic rod located in the middle of the top plate, with the telescopic end of the first hydraulic rod fixedly connected to the top of a positioning block. A mark is provided on the worktable directly below the positioning block. A second hydraulic rod is located corresponding to the front and rear of the first hydraulic rod, with the bottom of the telescopic end of the second hydraulic rod fixedly connected to the top of the pressing plate. A first pressure sensor is provided inside both the positioning block and the pressing plate.

[0006] Preferably, the bottom of the positioning block has a groove with a triangular front view section.

[0007] Preferably, the position adjustment mechanism includes limiting grooves disposed inside the front and rear ends of the base, and a threaded rod is installed inside the limiting groove, with one end of the threaded rod fixedly connected to the motor output end.

[0008] Preferably, the side extrusion mechanism includes movable support frames disposed on the left and right sides of the worktable. The bottom of the movable support frame is fixedly connected to the top of the slider. The inside of the slider is connected to the outside of the threaded rod by a thread. A translation plate is installed inside the movable support frame. The through hole inside the translation plate is slidably connected to the side of the positioning rod. The top left side of the translation plate is fixedly connected to the output end of the third hydraulic rod. A push plate is installed on the top right side of the translation plate. An extrusion block is provided on the right side of the push plate. A second pressure sensor is provided inside the extrusion block.

[0009] Preferably, the left sides of both ends of the extrusion block are fixedly connected to the right end of the limiting rod, and the side of the limiting rod is slidably connected to the through hole inside the left wall of the movable support frame.

[0010] Preferably, a partition plate is provided at the top of the middle of the base, and the partition plate is located in the middle of the movable support frame at both the front and rear ends of the base.

[0011] Preferably, the control module includes a frequency converter, a controller, and a hydraulic rod controller group. The frequency converter and the hydraulic rod controller group are connected to the controller through a control line. The controller is connected to the first pressure sensor and the second pressure sensor through a data line. The frequency converter is connected to the motor through a circuit. The hydraulic rod controller group is connected to the first hydraulic rod and the second hydraulic rod through lines respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The first hydraulic rod pushes the positioning block to move downward, and the triangular groove at the bottom of the positioning block is used to fix the middle position of the workpiece. The side extrusion mechanism and the pressing mechanism work together to fix and process the workpiece from multiple directions, which can quickly correct the workpiece with bent ends.

[0013] (2) The setting of the first pressure sensor and the second pressure sensor can monitor the pressure data in real time and feed the data back to the control module. The control module can accurately control each hydraulic rod and motor according to the feedback data to ensure the stability and consistency of the processing process and improve product quality.
