AI Technical Summary
Existing straightening equipment lacks precision in controlling the position of the pressure head, resulting in unstable finished product quality and an inability to adapt to different workpiece sizes and degrees of deformation.
The mounting bracket is driven by a drive source, which in turn drives the lead screw to rotate and move the sleeve on the guide rail. The position of the pressure head is precisely controlled by a slotted photoelectric sensor and a positioning arm. The structure is compact by using a synchronous belt drive.
It improves the control precision of the pressure head position, avoids excessive or insufficient travel distance, and ensures the stability and consistency of finished product quality.

[0031] Please refer to Figures 1-5 The orthopedic device provided by an embodiment of the present application comprises a mounting frame 10, a driving source 20 and an electric cylinder 30. The mounting frame 10 is fixed with a guide rail 121 for sliding cooperation with a sleeve 33 of the electric cylinder 30. The driving source 20 provides power as a power source and can drive the mounting frame 10 to slide linearly. The electric cylinder 30 comprises a motor 31, a screw rod 32 and the sleeve 33. The motor 31 is fixed with the mounting frame 10, the motor 31 can drive the screw rod 32 to rotate, the sleeve 33 is threadedly connected with the screw rod 32, and the sleeve 33 is slidingly connected with the guide rail 121. When the screw rod 32 rotates, the sleeve 33 can slide relative to the guide rail 121. One end of the sleeve 33 is provided with an opening for the screw rod 32 to extend into, and the other end of the sleeve 33 is provided with a pressure head 34. The pressure head 34 is used for contacting a workpiece and transmitting pressure during the orthopedic process, so as to realize orthopedic treatment of the workpiece.

[0033] The drive source 20 can be a pneumatic cylinder or a hydraulic cylinder. Preferably, the drive source 20 is a hydraulic cylinder, which provides more power output. Preferably, the motor 31 can be a servo motor or a stepper motor.
[0034] In one embodiment, the output shaft of the motor 31 and the lead screw 32 can be directly fixed together for transmission. For example, the output shaft of the motor 31 and the lead screw 32 have the same axis and can rotate synchronously.

When viewed along the first direction F1, a part of the positioning arm 50 extends into the sensing slot of the slotted photoelectric sensor.
[0038] In this embodiment, the sleeve 33 can slide along the first direction F1. When the sleeve 33 slides to the starting point, it will drive the positioning arm 50 to slide into the sensing groove of the slot-shaped photoelectric sensor, thereby feeding back the positioning information.
[0039] Further references can be made.

In a specific embodiment, the slot photoelectric sensor is fixedly installed on the second mounting plate 12 through the extension member 122. In this case, the extension member 122 extends out of the second mounting plate 12 along the first direction F1, so that the positioning arm 50 can directly extend upward to cooperate with the slot photoelectric sensor without the need to additionally form a structure such as a relief groove on the second mounting plate 12.
[0041] Specifically, the positioning arm 50 comprises a base 51 fixed on the sleeve 33, a positioning portion 53 extending into the slot photoelectric sensor, and a connecting portion 52 connecting the base 51 and the positioning portion 53. When viewed along the thickness direction of the second mounting plate 12, the positioning portion 53 does not overlap the second mounting plate 12.

[0044] It can be understood that in some embodiments, the orthopedic device can only be provided with the first mounting seat 60, i.e., one side of the device is pressed, and the other side provides a supporting function.
[0045] Of course, in some other embodiments, the orthopedic device can be further provided with a second mounting seat 80. The second mounting seat 80 is also provided with a cylinder 30 identical to that on the first mounting seat 60, so that the orthopedic device can accurately adjust the position of the pressure head 34 on both sides.
[0046] Specifically, referring to Figure 1The second mounting base 80 is provided with the mounting frame 10 and the electric cylinder 30, the electric cylinder 30 on the first mounting base 60 and the electric cylinder 30 on the second mounting base 80 are opposite to each other, and when the driving source 20 pushes the mounting frame 10 on the first mounting base 60, the distance between the two mounting frames 10 is reduced. In the embodiment, the orthopedic device is provided with the electric cylinder 30 on both sides, so that the position of the pressing head 34 can be accurately adjusted on both sides, and the orthopedic device can be applied to more possible deformation conditions of the workpiece.
[0047] Preferably, the second mounting base 80 can not be provided with the driving source 20.
[0048] Preferably, the mounting frame 10 is provided with a plurality of electric cylinders 30 in the second direction F2, and the second direction F2 is perpendicular to the axis direction of the screw rod 32. More preferably, the plurality of electric cylinders 30 are horizontally arranged on the mounting frame 10.

[0050] One arrangement is that one row of electric cylinders 30 on the left and one row of electric cylinders 30 on the right are one-to-one opposite to each other, and form a neat arrangement, and specifically, the pressing heads 34 of the two are opposite to each other; another way can refer to Figure 1 One row of electric cylinders 30 on the left and one row of electric cylinders 30 on the right are staggered, that is, the pressing head 34 on the first mounting base 60 is opposite to the space between the two pressing heads 34 on the second mounting base 80, and in this arrangement, it is more suitable for orthopedic treatment of some tubular or columnar workpieces.
[0051] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
